The owners have no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure as it appears in the Patent and Trademark Office patent files or records but otherwise reserves all rights whatsoever.

[0003] The present invention, in general, relates to personal grooming devices and, more particularly, to toenail or fingernail clippers.

[0004] As used herein, “nail clipper” includes either or both a toenail clipper and/or a fingernail clipper. Prior art versions of nail clippers are generally well known. The term “nail”, as used hereinafter, refers to either a′ fingernail or to a toenail or to both a fingernail and a toenail.

[0005] The current invention covers two generic types of nail cutting devices (i.e., nail clippers). The first type includes two (i.e., dual) parallel opposing blades where cutting edges of each of the blades face each other and are disposed parallel to each other at all times. This type of device cuts the nail across a portion of the width of the nail simultaneously on both the top and bottom of the nail, with the two simultaneous cuts intersecting (or nearly intersecting) proximate a middle of the nail. The current invention includes improvement to dual parallel opposing blade nail clippers.

[0006] The second type includes only one cutting blade that includes a cutting edge that abuts an opposing planar surface along the length of the cutting edge when the nail clipper is disposed in a closed position. The cutting edge of the cutting blade is parallel to the planar surface at all times. This type of device cuts the nail on one side of the nail simultaneously across a portion of the width of the nail, with the cut beginning at the top of the nail and extending downward until the nail is severed. The current invention improves single blade nail clippers of the type that include a cutting edge which abuts a planar surface in the closed position.

[0007] Both the first and second type of nail clipper are of a parallel cut class (or type) of nail clipper because for either class (or type) a parallel cut is occurring simultaneously across a portion of a width of the nail. This is different than a scissor-cut, as described below, where a cut is occurring at a point and not across a line of cut. The line of cut for the first and second type of nail clipper includes that portion of the width of the nail that is being severed. Accordingly, the current invention improves parallel cut types of nail clippers.

[0008] Reference is often made in this document to “dual parallel opposing blade types of nail clippers” or to “prior art dual parallel opposing blade types of nail clippers.” Dual parallel opposing blade types of nail clippers, in general, provide certain benefits that are not available with other types of nail clippers, such as scissor-cut types of nail clippers. The current invention also provides several new and very important benefits that are not available with any of the prior art dual parallel opposing blade types of nail clippers. These important benefits are described herein.

[0009] As used herein, dual parallel opposing blade types of nail clippers include an upper cutting blade attached to an upper frame member and a lower cutting blade attached to a lower frame member. The upper blade includes an upper cutting edge and the lower blade includes a lower cutting edge.

[0010] Dual parallel opposing blade types of nail clippers include an open position in which the upper and lower cutting edges are disposed apart from each other and are parallel with respect to each other. Dual parallel opposing blade types of nail clippers also include a closed position in which the upper and lower cutting edges are also parallel with respect to each other. In the closed position, the upper and lower cutting edges are disposed closer to each other in the closed position than in the open position. It is preferable for the upper and lower cutting edges to abut each other in the closed position, however, they may be slightly offset and thereby disposed adjacent to each other in the closed position. The drawings and descriptions provided, herein, show the cutting edges for the dual parallel opposing blade embodiments of the invention as abutting one-another, however, they may be modified to include a slight offset, if desired.

[0011] Certain newer prior art dual parallel opposing blade types of nail clipper presently include plastic coverings that extend over portions of the prior art steel frame nail clippers. While this approach may provide a novel color or a different feel it also increases weight because the added plastic can only increase the weight of the already heavy prior art nail clipper. It is not generally desirable to increase the weight of any nail clipper as this makes transportation of the nail clipper more difficult to accomplish. It is desirable to decrease the weight of a nail clipper and to do so at reasonable cost. For example other metals, such as titanium, could conceivably be used to modify prior art steel frame nail clippers and make them lighter; however, doing so would also incur a severe cost increase.

[0012] Therefore, there is a need for a lighter and preferably less-expensive similar type of nail clipper. Applying a plastic coating to existing steel frame nail clippers fails to satisfy this objective.

[0013] Additionally, prior art dual parallel opposing blade types of nail clippers also include a considerable amount of metal (i.e., steel) that has been machined, or stamped or otherwise formed and assembled together. This is considerably more expensive than plastic, as far as raw material costs are concerned and also as far as fabrication cost is concerned. However, little change has occurred because the mechanical stresses arising during use have precluded the practical durable use of a plastic body in any type of nail clipper that includes cutting of at least a portion of the width of the nail using a blade that is substantially parallel with respect to the plane of the nail. Simultaneously cutting across the width or portion of the width of the nail requires considerable force to accomplish, as the nail is hard and resists cutting considerably more than would occur if using a scissor-type of nail clipper.

[0014] Prior art dual parallel opposing blade types of nail clippers apply the cutting force to the upper and lower steel frame members, which must transfer that force through the steel frame members to the blades at the front of each of the steel frame members. A resistance to cutting the nail results in the application of a resistive force being applied (by the nail) to each of the blades. The resistive force is in an opposite direction as compared to the direction of cutting force that is applied to each of the steel frame members. Opposing direction forces applied to the same member result in shear, or shear force, being experienced by the member. Therefore, each of the steel frame members experience shear during cutting of the nail. If the frame members of prior art dual opposing parallel blade types of nail clippers were not made of steel but were instead made of a softer material they would eventually either break or bend. The reason prior art dual parallel opposing blade types of nail clippers have maintained the use of sufficiently high-grade steel for the fabrication of their frame members is because steel is strong enough to withstand the shear force and to resist bending in response to these forces.

[0015] It is impossible to avoid the occurrence of these forces during use with dual parallel opposing blade types of nail clippers. However, there remains a long-standing need to improve the design of dual parallel opposing blade types of nail clippers so that materials other than steel can be used to form the upper and lower frame members. In particular, there remains a long-standing need to improve the design of dual parallel opposing blade types of nail clippers so that the upper and lower frame members can be formed of a polymer (plastic) or other non-metallic material.

[0016] Similar opposing forces are also experienced by the single blade nail clipper of the type that includes a cutting edge which abuts a planar surface. Therefore, the frame members of the single blade nail clipper also experience shear. Accordingly, similar needs, as described herein for dual parallel opposing blade types of nail clippers, also apply to the single blade nail clipper of the type that includes a cutting edge which abuts a planar surface. Therefore, the benefits provided by the current invention apply to dual parallel opposing blade types of nail clippers and also to the single blade nail clippers of the type that include a cutting edge which abuts a planar surface along the length of the cutting edge.

[0017] A parallel cutting blade or pair of parallel opposing cutting blades is substantially different than a scissor-type of cutting action that cuts the nail at a point (as opposed to along a line across a width of the nail.) During use when cutting with a scissor-type of cut, a point of cutting moves across the width of the nail as the scissor-cut progresses. Because the scissor-type of nail clipper is always severing the nail at a point and not along a line, it experiences lower operating forces during cutting and only the smallest fraction of mechanical stress or shear force as compared to what is experienced by a nail clipper that uses a cutting blade that is parallel to the plane of the nail and which simultaneously severs a portion of the width of the nail. Considerably less stress is experienced with the scissor-cut than occurs with a cutting blade that is generally parallel with respect to the plane of the nail. Accordingly, a scissor-cut type of nail clipper that includes a steel blade and plastic body is known. See U.S. Pat. No. 4,819,673 to McMullen, Jr.

[0018] However, the scissor-cut has certain substantial disadvantages that occur when attempting to cut a nail as compared to a parallel type of cutting action. When cutting a nail with a scissor-cut type of nail clipper it is necessary to supply a significant force constantly urging the nail toward the scissor blades and urging the scissor blades toward the nail. This is because the closing of the angled scissor blades during cutting also always applies a force against the nail that tends to urge the nail away from the blades at the point of cutting. The user must compensate for this force with an opposing force urging the nail and the scissor blades toward each other until the cut is completed.

[0019] If, during a cutting of the nail with a scissors-type of nail clipper, the user slips there is risk that the fleshy part of the finger or toe can be urged into contact with the scissor blades, cutting the finger or toe. Also, because cutting is occurring at a point (and not along a line) there is danger of removing more of the nail than desired. When a parallel type of cutting of the nail occurs the user is able to better judge the depth of cut, although prior art types of nail clippers also have some risk of removing more or less of the nail than desired.

[0020] Additionally, the user of a scissor-type of nail clipper must constantly change the position of the nail clipper relative to the nail during cutting to follow the contour of the nail in order to obtain the desired curvature. Alternately, numerous smaller cuts can be made. Either approach increases the time required to cut each nail. Also, the overall cut may not provide the desired contour of the finished nail.

[0021] By way of contrast, after initial placement no additional force is required by the user to maintain a nail in position with respect to the cutting blades of the dual parallel opposing blade type of nail clipper or with respect to the single blade nail clipper of the type that includes a cutting edge which abuts a planar surface. As the cut begins, the parallel opposing cutting blades or the single blade immediately begins to cut into, and thereby, clamp and secure the nail in position relative to the opposing blade or relative to the planar surface.

[0022] There is also much less risk of injury with a parallel cutting blade type of nail clipper. It is also faster. Additionally, the parallel cutting blade or blades can include a curvature, if desired, that approximates a desired finished contour of the nail, thereby eliminating the need for numerous additional small cuts. The use of a curved dual parallel opposing blade type of nail clipper can lessen or even eliminate the need for filing of the nail after cutting. It is also easier to control the depth of cut (i.e., how much nail material is removed) with certain examples of a dual parallel opposing blade type of nail clipper using novel depth-limiting improvements, as described, herein. These depth-limiting improvements also apply to certain single parallel cutting blade versions of the invention.

[0023] The prior art parallel cut type of nail clippers include a pair of parallel opposing steel blades that are integrally formed with opposing steel upper and lower frame members. The steel blades may be detachable with respect to the frame members. See FIG. 3 of U.S. Pat. No. 6,941,657, to Choi et al, that issued on Sep. 13, 2005. A ridge that is provided in a steel center post (rod) engages with a steel pivoting lever and, together, are used to supply a force sufficient to urge the opposing frame members (and the dual parallel opposing blades) toward one-another sufficient to sever the nail along a width of the nail that is disposed between the opposing blades.

[0024] For the above described structural reasons, the body, opposing blades, lever, and post of the prior art dual parallel opposing blade devices are all made from metal, such as steel. The prior art dual parallel opposing blade nail clippers include an upper and lower half of the body, with each half of the body including one blade portion that includes a cutting edge and with each blade portion disposed generally on a plane that is at an angle with respect to a remainder of the body. Each of the upper and lower halves of the body is generally disposed on a more horizontal plane and each of the blade portions is generally disposed on a more vertical plane. The two halves of the body are joined together during manufacture, taking care to ensure that the cutting edges of the blades are in alignment with respect to each other.

[0025] The machining of the opposing two halves of the body, bending the opposing halves to form the blades at nearly a right angle with respect to a remainder of the upper and lower frame members, and ensuring that the opposing blades align with one another and that the blades will abut against one another when the prior art nail clipper is disposed in a closed position (after finishing a cut) is difficult and, therefore, adds to the cost of manufacture. Also, fastening together the opposing sides (i.e., the upper and lower frame members) of the body, as well as the cost of the steel and the large amount of steel that is used, together, further contribute to increasing the relatively high cost of these prior art types of dual parallel opposing blade types of nail clippers.

[0026] The second type of device that includes a single blade with a cutting edge that abuts an opposing planar surface along the length of the cutting edge when the nail clipper is disposed in a closed position is believed to be novel.

[0027] Accordingly, there is a need for an embedded member single blade or an embedded member dual blade nail clipper that makes a parallel cut which is inexpensive to manufacture. There is a need for an embedded member single blade or an embedded member dual blade nail clipper that makes a parallel cut which includes at least one embedded member that is in vertical alignment with a cutting force that is applied to a front portion of an upper frame member and/or a front portion of a lower frame member, wherein the embedded member is disposed in the front portion of the frame member, and wherein the embedded member is able to sufficiently stiffen a front portion of the upper frame member and/or a front portion of the lower frame member of the nail clipper sufficient to withstand a cutting force that is applied to either of the frame members. There is a need for an embedded member single blade or an embedded member dual blade nail clipper that lessens the adverse effects of shear sufficient to permit the use of plastic or other non-metallic materials in the frame members. There is a need for an embedded member single blade or an embedded member dual blade nail clipper that is able to decrease a magnitude of shear force experienced by an upper frame member or by a lower frame member or by both the upper frame member and the lower frame member during cutting of the nail. There is also a need for a disposable parallel cutting blade class (i.e., either an embedded member single blade or an embedded member dual blade type) of nail clipper that is inexpensive to manufacture.

[0028] If sufficiently inexpensive, such a nail clipper could be given away or offered to guests at finer hotels or it could be sold at a lower cost than currently available prior art parallel cut types of nail clippers. There is need for a nail clipper that can meet any of these needs and which also has at least one parallel cutting blade that is able to sever a nail across at least a portion of the width of the nail that is disposed under the cutting blade and above the planar surface or between the cutting blades during use.

[0029] There is also a need to include, as desired, advertising on a nail clipper. There is also a need to provide a lighter-weight type of nail clipper.

[0030] A need with prior art types of dual parallel opposing blade types of nail clippers is to ensure that the cutting edges of the blades abut (or very nearly abut) against each other when the nail clipper is urged into the fully closed position. An offset between the prior art blades could make cutting difficult to accomplish. An offset between the cutting edges could also result in an uneven cut and a resulting ragged edge of the cut nail. Accordingly, there is a need to more inexpensively or easily align opposing cutting blades of a dual parallel opposing blade type of nail clipper. Similarly, there is also a need to provide a parallel cutting blade type of nail clipper that allows for alignment between a pair of opposing cutting edges of opposing blades during manufacture at low cost.

[0031] It is also desirable to provide as many of these benefits as possible while forming the blades out of steel or any other desired suitable material, such as a ceramic or composite material, and forming the body out of a plastic, polymer, nylon, synthetic or other non-metallic type of a material that is different than the material used to form the blade, in which the structural part of the body that experiences the cutting forces and which holds the blades in position relative to each-other, is not formed of a steel or of a metal. While steel is a desirable material to use in the manufacture of the blades for many versions of the current invention, it is desirable and an object of the invention, to form the greater portion of the upper and the lower frame members of a dissimilar material as compared to the blades.

[0032] It is also desirable and an object that plastic (or any preferred polymer, nylon, or other synthetic material) be employed as the dissimilar material that is used to form the upper and lower members of the current nail clipper, and that the dissimilar material also be used to secure each of the blades thereto with cutting edges of the blades facing one another.

[0033] It is further desirable and an object that a horizontal portion of the blades are embedded in the plastic (i.e., in the dissimilar and non-metallic) material that is used to form the upper and lower members of the nail clipper. As used herein, the term “embedded” includes partial embedding as well as “surround, full or complete” embedding. Partial embedding, as used herein, refers to where only a portion of the horizontal portion of the blade is surrounded by the plastic (dissimilar) material in which the plastic (dissimilar) material does not extend fully around any portion of the blade. Surround, full or complete embedding, as used herein, refers to where at least a portion of the horizontal portion of the blade is encased, surrounded, or covered with the plastic (dissimilar) material.

[0034] It is an even further desirable and important object that the horizontal portion of the blades that is embedded in the plastic (dissimilar material) is extended sufficiently far into the plastic (dissimilar material) to effectively reinforce the plastic in the area where the greatest stress and strain is experienced during use and to also transfer cutting forces to the cutting edges of the blades while helping to prevent damage from occurring to the plastic (i.e., dissimilar) material that is used to form the upper and lower members of the nail clipper.

[0035] It is preferred that the blade(s) include as an improvement the horizontal portion, and that each horizontal portion extend sufficiently far into the upper and lower frame members so as to ensure that the horizontal portion of the blade (for single blade versions) or the horizontal portion of the blades (for dual blade versions) is/are in vertical alignment with the forces that are applied to the upper and lower frame members during cutting. As described herein, this (i.e., the embedded horizontal portions) increase stiffness and strength of the upper and lower frame members in this critical area. The embedded horizontal portions help to ensure that the upper and lower frame members, which can now be fabricated from low cost plastic, are able to withstand a greater magnitude of shear force (than without the embedded horizontal portions) and this improvement also helps to lessen the magnitude of shear force that is experienced by the upper and lower frame members by converting a portion of the shear force into a compressive force that is experienced by the upper and lower frame members, thereby decreasing the magnitude of shear force experienced by the upper and lower frame members.

[0036] After having had benefit of the teachings, herein, it is possible to include a discreet embedded member within the upper and lower frame members where the discreet embedded member extends sufficiently far into the frame members to ensure that a portion of the discreet embedded member(s) is/are in vertical alignment with the forces applied to the frame members during use (i.e., cutting). Use of the discreet embedded member(s) can be used instead of the embedded horizontal portions providing that the blade (for single blade versions) or the blades (for dual opposing blade versions) is otherwise secured to the plastic (non-metallic) frame members. While use of the horizontal portion of the improved blade(s) is/are preferred as the inventive embedded member, the use of the discreet embedded member(s), as disclosed and described herein, is also possible and anticipated.

[0037] Past, current and future advances in 3D printing, injection and other molding technologies are anticipated to be used to form the plastic (dissimilar material) body of the current invention (i.e., the upper and lower frame members). The body could be molded as an integral one-piece component with the dual opposing blades attached thereto during a desired step of manufacturing. This, if accomplished, would eliminate the need for precisely controlling tolerances as have historically been necessary during the manufacture of prior art steel frame types of dual opposing blade nail clippers.

[0038] It is desirable to use plastic (i.e., polymer or other non-metallic material) to form the upper and lower frame members of the body of the current nail clipper and include the cutting blades in the body during molding or manufacture of the nail clipper.

[0039] Although a one-piece polymer structure is disclosed as one possible preferred embodiment, if desired, identical (or nearly so) discreet polymer upper and lower frame members could be provided that are inverted with respect to each other and then later joined (secured) together by any preferred means. By controlling position during joining or by trimming a distal end to control the overall length of the polymer upper and lower frame members to match one-another prior to joining the upper and lower frame members together, positioning of the opposing cutting edges of the blades to ensure that they abut one-another in the closed position can be precisely, easily and inexpensively controlled during manufacture.

[0040] Other advances in molding technology are anticipated to be used, as desired, for manufacture of the current invention or to modify it, as may later be desired. For example, it may be desirable to form the body out of two or more different types of polymer (or other non-metallic) material. This approach could be optimally applied to provide the necessary structural rigidity and also a particular desired texture or feel to the nail clipper during use. For example, a sufficiently strong and rigid type of plastic could be used to form the structural portion of the body that experiences the stress and strain (i.e., forces) during cutting while a more elastic material could also be used (for example, injected) at a distal end of the nail clipper (i.e., maximally away from the cutting blades) proximate where an upper portion of the body and a lower portion of the body connect together or are fastened together. The more elastic material could also function as an elastomeric wedge, as disclosed in currently pending application Ser. No. 13/385,701, entitled, “Nail Clipper with Opposing Parallel Blades,” that was filed on Mar. 1, 2012, to supply a greater force that helps urge the upper portion away from the lower portion, thereby providing space for inserting a portion of a nail, there-between.

[0041] As mentioned previously, this connection could be accomplished by molding the upper and lower portions as an integral one-piece assembly. Alternately as mentioned above, the upper and lower portions could be molded as individual component parts and later joined together, such as by fusion welding, sonic welding, adhesive, banding, clamping or by any other preferred means such as the use of a desired type of fastener. One preferred means of securing discreet upper and lower frame members together is described, herein.

[0042] If the body (where “body” and “frame” are used interchangeably herein) were formed out of two or more different types of material, differences between the color of the materials could be advantageously used to provide a desired aesthetic appearance, accent, or injected to provide a surface with a different texture (i.e., coefficient of friction) or a different contour (either a raised or recessed surface), or to provide desired markings, such as letters, numbers, symbols, a logo, etc. These enhancements, though not described in detail, are anticipated by the present disclosure.

[0043] When compared to all-steel prior art dual parallel opposing blade types of nail clippers the current design enhancements provide many significant benefits not previously available. These benefits encompass structural, aesthetic, cost of manufacture, ease of manufacture, safety, storage, lower weight, decreased use of steel, use of plastic or other non-metallic material to form the upper and lower frame members, functionality improvements, and enhanced ease of use advantages.

[0044] It is desirable also to include, as preferred for certain versions of the invention, a structure for containing nail fragments that break off during cutting. If the body is molded it then also becomes possible to include sidewalls that are molded to the frame members and which help create a structure that is able to contain cut nail fragments.

[0045] It is also desirable to include, as preferred for certain versions of the invention, an inventive safety bumper that helps ensure that only a desired amount of the nail is removed and which further lessens the possibility of personal injury during use.

[0046] Also, because prior art nail clippers include so much metal, they are often detected during airport security screening which can then result in the searching of personal sundries that would not otherwise be so scrutinized. They may even be confiscated as a potentially dangerous weapon, which of course is a debatable assessment, but if confiscated it leaves the person without a nail clipper when they reach their destination. It is desirable to include sufficiently little metal with a nail clipper so that it does not generally register as a potential threat during airport security screening procedures. Minimizing the amount of metal (i.e., steel) that is included in an embedded member single blade or in an embedded member dual blade parallel cut type of nail clipper is an object of the present invention.

[0047] The machining of a cutting edge into the opposing blades of a prior art type of dual parallel opposing blade type of nail clipper is relatively expensive to accomplish. Additionally, the aligning of the cutting edges so they abut against each other or are otherwise sufficiently close to each other in the closed position increases the difficulty and cost of manufacture of prior art nail clippers. It is an object of the invention to provide an improved blade that can be embedded in a plastic (or other non-metallic) upper frame member of an embedded member single blade parallel cut nail clipper or additionally embedded in a plastic (or other non-metallic) lower frame member of an embedded member dual blade parallel cut nail clipper. It is an object that the improved blades lower the cost of manufacture. For the embedded member dual parallel opposing blade nail clipper it is also a further object to provide a desired degree of alignment between the cutting edges of the opposing blades at lower cost.

[0048] There are two additional long-standing problems common with all prior art dual parallel opposing blade types of nail clippers that occurs as a type of a lever that cooperates with a center rod is depressed. The lever can always rotate around a center longitudinal axis of the center rod that passes through the frame of the nail clipper. This rotation is useful under certain conditions because it allows the nail clipper to be intentionally urged into a more compact rest (i.e., a storage or transit) position. However, when actually cutting a nail, considerable force is applied to the lever. If as increasing force is applied, the lever unintentionally rotates around the center longitudinal axis of the center rod, the direction of force that is being applied to the nail clipper can suddenly change. This can cause the nail clipper to become dislodged from its position of cooperation with the nail. The cutting edge(s) of the blade(s) can accidently be urged, with sudden and considerable force, against a fleshy part of the finger, possibly cutting the finger. Therefore, there is a need to prevent inadvertent rotation of the lever of the nail clipper around the longitudinal axis of the center rod during cutting of the nail. This is true for embedded member single blade parallel cut versions and embedded member dual blade parallel cut versions of the nail clipper. There is a similar need to be able to prevent the lever from similarly rotating when the nail clipper is disposed in the rest or transit position. Inadvertent rotation around the longitudinal axis of the center rod can urge the nail clipper out of the rest or transit position increasing its bulk, which is undesirable. No effective prior solution exists for either of these long-standing problems.

[0049] Therefore, a parallel cutting type of nail clipper that provides any of the benefits discussed herein, is especially desirable.

[0050] Accordingly, there exists today a need for an embedded member nail clipper that helps to ameliorate the above-mentioned problems and difficulties as well as ameliorate those additional problems and difficulties as may be recited in the “OBJECTS AND SUMMARY OF THE INVENTION” or discussed elsewhere in the specification or which may otherwise exist or occur and that are not specifically mentioned herein.

[0051] As various embodiments of the instant invention help provide a more elegant solution to the various problems and difficulties as mentioned herein, or which may otherwise exist or occur and are not specifically mentioned herein, and by a showing that a similar benefit is not available by mere reliance upon the teachings of relevant prior art, the instant invention attests to its novelty. Therefore, by helping to provide a more elegant solution to various needs, some of which may be long-standing in nature, the instant invention further attests that the elements thereof, in combination as claimed, cannot be obvious in light of the teachings of the prior art to a person of ordinary skill and creativity.

[0052] Clearly, such an apparatus would be most useful and is especially desirable.

[0053] Nail clippers are, in general, known. For example, the following patent documents describe various types of these devices, some of which may have some degree of relevance to the invention. Other patent documents listed below may not have any significant relevance to the invention. The inclusion of these patent documents is not an admission that their teachings anticipate any aspect of the invention. Rather, their inclusion is intended to present a broad and diversified understanding regarding the current state of the art appertaining to either the field of the invention or possibly to other related or even distal fields of invention.

[0166] Briefly, an embedded member nail clipper that is constructed in accordance with the principles of the present invention has a main body or frame consisting of a plastic or other non-metallic material, such as any desired polymer, nylon or formed of any preferred non-metallic material or combination of non-metallic materials. The nail clipper includes at least one blade that makes a parallel cut simultaneously across a portion of a top of a nail. A single blade version of the invention includes an upper blade attached to an upper frame member that makes a parallel cut simultaneously across a portion of the top of the nail. For the single blade version (only) the lower frame member includes a planar surface attached, thereto. An upper blade cutting edge of the upper blade makes contact with (i.e., abuts) the planar surface along the longitudinal length of the upper blade cutting edge when the single blade version is disposed in the closed position. For certain single blade versions the planar surface is formed of the same material used for the lower frame member. For certain other single blade versions an optional hardened planar insert is attached to the lower frame member and disposed under the upper blade cutting edge. When included, the hardened planar insert provides the planar surface that the upper blade cutting edge contacts when the single blade nail clipper is disposed in the closed position. For the single blade version of the invention the upper blade cutting edge is always parallel with respect to a plane of the planar surface regardless of the position of the single blade version of the invention. The upper blade includes a horizontal portion having any preferred cross-sectional shape or overall length that is formed integrally with a remaining portion of the upper blade. An optional lower blade, for use with a dual parallel opposing blade version of the invention, as further described below and in the detailed description, is similarly or identically constructed as compared to the upper blade. The lower blade can also include any modification(s) described herein for the upper blade or vice-versa. As much as possible of the horizontal portion is embedded in a front portion of the frame member. A planar shape is generally preferred for the horizontal portion. Cylindrical and other cross-sectional shapes for the horizontal portion of the upper blade and the lower blade are also possible and are described, herein. The horizontal portion of the upper blade extends into the upper frame member sufficiently far to ensure that a cutting force that is applied to the upper frame member during cutting of the nail is disposed in vertical alignment with at least a portion of the horizontal portion of the upper blade. The horizontal portion of the upper blade and the horizontal portion of the lower blade are disposed on a horizontal plane. The horizontal plane is parallel with respect to the front portion of the upper frame member for the upper blade, and is parallel with respect to a front portion of the lower frame member for the lower blade. The remaining portion of the upper blade includes the upper blade cutting edge and is generally disposed along a first vertical plane that is disposed at an angle with respect to the horizontal plane of the horizontal portion of the upper blade. The remaining portion of the upper blade is vertical or nearly vertical. A remaining portion of the lower blade that includes a lower blade cutting edge is generally disposed along a second vertical plane which is disposed at an angle with respect to the horizontal plane of the horizontal portion of the lower blade. The remaining portion of the lower blade is vertical or nearly vertical. The first vertical plane and the second vertical plane are the same only when the first and second vertical planes are both vertical. Otherwise, a slight desired angular offset occurs between the first vertical plane and the second vertical plane, however both the first and second vertical planes are generally disposed in a more vertical orientation than is the horizontal plane of the horizontal portion of the first blade or the horizontal portion of the second blade. According to a first general modification that is applied to the upper blade of the single blade version or to the upper blade of a dual parallel opposing blade version, a shortened modified upper blade (i.e., that includes a shortened horizontal portion) or which includes a wrap-around upper blade can be included that does not necessarily extend sufficiently far into the upper frame member to ensure that a portion of the shortened modified upper blade or a portion of a wrap-around portion of the wrap-around upper blade is disposed in vertical alignment with respect to the downward cutting force that is applied to the upper frame member, providing that an upper horizontal discreet member having any preferred cross-sectional shape or overall length is embedded in the front portion of the upper frame member and providing that the upper horizontal discreet member extends sufficiently far into the upper frame member to ensure that the cutting force that is applied to the upper frame member is disposed in vertical alignment with at least a portion of the upper horizontal discreet member. The lower blade may include a similar horizontal portion. The horizontal portion of the lower blade includes any preferred cross-sectional shape or overall length and is formed integrally with the remaining portion of the lower blade. The dual parallel opposing blade version of the invention includes the lower blade. For the dual parallel opposing blade version, as much as possible of the horizontal portion of the lower blade is also embedded in the front portion of the lower frame member. The horizontal portion of the lower blade is formed integrally with respect to the remaining portion of the lower blade. With the dual parallel opposing blade version the lower frame member does not include the planar surface. The lower blade cutting edge is opposed to the upper blade cutting edge of the upper blade. Therefore, the lower blade is inverted (i.e., rotated 180 degrees about a center longitudinal axis of its horizontal portion) with respect to the upper blade. When the dual parallel opposing blade version is disposed in the closed position the upper blade cutting edge preferably contacts (i.e., abuts) the lower blade cutting edge along a longitudinal length of the cutting edges. The upper blade cutting edge and the lower blade cutting edge are always parallel with respect to each other regardless of which position that the dual parallel opposing blade version of the nail clipper is disposed in. Alternately, the upper blade cutting edge and the lower blade cutting edge may include a slight overlap with respect to each other when the dual parallel opposing blade version is disposed in the closed position. The dual parallel opposing blade version makes a parallel cut simultaneously across the top and across a bottom of a portion of the nail. The horizontal portion of the lower blade may optionally extend into the lower frame member sufficiently far to ensure that an opposing cutting force that is applied to the lower frame member during cutting of the nail is disposed in vertical alignment with at least a portion of the horizontal portion of the lower blade. According to a second general modification that is applied to the lower blade of the dual parallel opposing blade version, a shortened modified lower blade (i.e., that includes a shortened horizontal portion) or which includes a wrap-around lower blade can be included that does not necessarily extend sufficiently far into the lower frame member to ensure that a portion of the shortened horizontal portion of the shortened modified lower blade or a portion of a wrap-around portion of the wrap-around lower blade is disposed in vertical alignment with respect to the opposing cutting force, providing that a lower horizontal discreet member having any preferred cross-sectional shape or overall length is embedded in the front portion of the lower frame member or providing that one or more vertically extending sidewalls are attached to the lower frame member or providing that reinforcing strands or fibers are embedded in the polymer of the lower frame member. According to one general form of the invention, the frame, when viewed from the side, somewhat resembles an elongated “U-shape” in appearance. Alternately for another general form of the invention when similarly viewed from the side, the frame may include a generally “V-shape”. Other preferred shapes are also possible. For certain preferred embodiments the frame is formed (typically molded) as a one-piece assembly. For other preferred embodiments, the upper frame member and the lower frame member of the frame are formed as separate component parts and, during manufacture, are secured together by any preferred means. For the single blade version of the invention the nail clipper includes an open position in which the nail can be inserted under the upper blade cutting edge of the upper blade and above the planar surface. For the dual parallel opposing blade version of the invention the nail can be inserted under the upper blade cutting edge of the upper blade and above the lower blade cutting edge of the lower blade when the nail clipper is disposed in the open position. An included lever is depressed which causes the upper blade cutting edge of the single blade version or the opposing upper blade and lower blade cutting edges of the dual parallel opposing blade version to sever the nail and dispose either version of the nail clipper into the closed position. The nail clipper also preferably includes a rest position in which a longitudinal axis of the lever of the nail clipper is disposed in parallel longitudinal alignment with respect to a longitudinal axis of the nail clipper and where a longitudinal length of the lever is disposed substantially adjacent to a top or bottom surface of the nail clipper. Means are optionally provided for preventing the lever from pivoting around a center longitudinal axis of a center rod that the lever is operatively connected to during a cutting of the nail. The lever includes a fulcrum or edge which, during use, bears down upon an upper surface of the upper frame member to apply the first downward force to the upper frame member. During a cutting of the nail, according to a preferred embodiment that includes a pair of elevated vertical sidewalls attached to the lower frame member, the fulcrum of the lever urges the upper surface of the upper frame member below an upper edge of the two opposing vertical sidewalls of the lower frame member. When, during the cutting of the nail, the upper surface of the upper frame member is urged below the upper edge of the vertical sidewalls, a portion of the lever is also then disposed below the upper edge of the vertical sidewalls. This maintains the longitudinal axis of the lever in parallel alignment with respect to a longitudinal axis of the nail clipper for the duration of the cutting of the nail, which helps prevent injury to the user. The two opposing vertical sidewalls stiffen the lower frame member, to which they are preferably attached as molded extensions of the lower frame member. The vertical sidewalls, in combination with a remainder of the nail clipper, form a container for capturing nail clippings that are severed from the user's nail. The container, in this manner provides three simultaneous benefits; first by a capturing of nail clippings, second by maintaining the longitudinal axis of the lever in parallel alignment with the longitudinal axis of the frame (i.e., main body) of the nail clipper and third by reinforcing the lower frame member an amount sufficient to increase its ability to withstand the stress and shear force during cutting. The lever is preferably made from a sufficiently strong and rigid plastic, although any desired material may be used to form the pivoting lever. The lever may include any preferred size, shape or ornamental design. As desired, a reinforcing member is disclosed that can be molded or embedded into the lever to increase its strength. If desired, the invention can be adapted for use with a prior-art type of lever. During use, the fulcrum applies the first downward force in a downward direction to the upper surface of the upper frame member which urges the upper frame member in a downward direction. During use, a portion of the fulcrum becomes disposed below the upper edges of the two opposing vertical sidewalls of the lower frame member. The fulcrum, and therefore the entire lever, is prevented from side to side movement as would occur if the lever were able to continue rotation around the center longitudinal axis of the center rod. At the same time as the fulcrum is urged in a downward direction, a U-shaped recessed area of the lever is proportionally raised above the upper surface of the upper frame member which, in turn, applies the second opposing force in an opposite second or upward direction as compared to the first force. A pin passes through openings provided in the U-shaped recessed area of the lever that is located at a lower, front end of the lever. The pin also passes through an opening provided in an upper end of the center rod. When the lever is depressed the pin applies the second opposing upward force to the center rod. The second opposing force, in turn, is attempting to urge the center rod in an upward direction at the same time the fulcrum is urging the upper frame member in a downward direction. A lower or bottom end of the center rod preferably includes an enlarged head that applies at least a portion of the second upward force to a bottom surface of the lower frame member. If desired, the lower end of the center rod can be attached to the lower frame member to transfer the second opposing upward force to the lover frame member by any preferred means, including the use of a lower pin connecting the lower end of the center rod to the lower frame member or by molding the center rod as an integral upward extension of the lower frame member. The second upward force prevents the lower frame member from being urged further downward and away from the upper frame member during cutting of the nail. If the vertical sidewalls are attached to the lower frame member, the lower frame member will not be as flexible as the upper frame member. Therefore, the upper frame member will experience the greater degree of flexing during cutting of the nail. For certain embodiments, the upper frame member and the lower frame member are similarly flexible. If they are similarly flexible both the upper frame member and the lower frame member will experience a similar amount of flexing during use. Gradually urging the distal end of the lever downward progressively urges the upper frame member and the lower frame member toward each other until the nail clipper is disposed in the closed position, at which time the portion of the nail that was disposed under the upper blade cutting edge (and, if included above the lower blade cutting edge) has been severed to provide the nail clipping that has been captured in the container, if the container is included. Because the vertical sidewalls are optional, the container can be omitted for certain versions of the invention (either single or dual blade versions) by omitting the vertical sidewalls. The embedded horizontal portion of the upper blade provides structural reinforcement to the front end of the upper frame member of the frame. During application of the first downward force the horizontal portion of the upper blade helps to transfer a portion of the first downward force to the upper blade by compression rather than by shear force. This reduces a magnitude of shear that is experienced by the front portion of the upper frame member and allows for cutting of the nail without causing damage to the plastic (or non-metallic material) of the upper frame member. This, in turn, allows the use of less durable and less expensive polymers for construction of the upper frame member. If included, the upper horizontal discreet member similarly provides structural reinforcement and increased ability to withstand shear to the front end of the upper frame member of the frame and the upper horizontal discreet member similarly helps to transfer a portion of the first downward force to the upper blade by compression rather than by shear. Similarly, the bottom end of the center rod that applies the second force to the lower frame member preferably contacts the bottom surface of the lower frame member at a location below a portion of the horizontal portion of the lower blade that is embedded into the front end of the lower frame member. The horizontal portion of the lower blade provides structural reinforcement and increased ability to withstand shear to the front end of the lower portion of the frame. During application of the second upward force (for dual parallel opposing blade versions of the invention) the horizontal portion of the lower blade helps to transfer a portion of the second force by compression to the lower blade rather than by shear force. This reduces shear that is experienced by the front portion of the lower frame member and allows for cutting of the nail without causing damage to the plastic (or non-metallic material) of the lower frame member. This, in turn, allows the use of less durable and less expensive polymers for construction of the lower frame member. If included, the lower horizontal discreet member similarly provides structural reinforcement to the front end of the lower frame member of the frame and the lower horizontal discreet member similarly helps to transfer a portion of the second upward force to the lower blade by compression rather than by shear. The embedded reinforcing strands or fibers provide similar benefit. Therefore, the embedded horizontal portions of the upper and lower blades or the upper and lower horizontal discreet members or the reinforcing strands or fibers allow the frame (i.e., the upper frame member and the lower frame member) of the nail clipper to be made mostly from plastic or other desired non-metallic material and to withstand the considerable forces that are experienced by the upper and lower frame members when a parallel cut of the nail occurs across a length of the cutting edge (or cutting edges) of the blade (or blades). Accordingly, the disclosed structures provide a stronger, more durable and also a less expensive nail clipper. Additionally, the use of various or multiple colored or textured polymers allow for greater variation in visual appearance as well as considerable design options for enhancing aesthetic appeal, safety, and ease of use of the nail clipper. Numerous modifications, safety improvements to the blade, an ability to file a nail as it is being cut and other optional novel component parts are described, herein along with the benefits provided. The nail clipping, at the moment of it being severed from a remaining portion of the nail, is rapidly urged away from the nail. The nail clipping is preferably captured between the vertical sidewalls and by a remainder structure of the nail clipper that together form the container. This is preferred as the nail clipping is not ejected from the nail clipper and scattered in the vicinity of the user. When the user wishes to remove the accumulated nail clippings from the container, the user inverts the nail clipper over a waste basket with the nail clipper disposed in the open position and the blade(s) facing downward. The user then vertically shakes the nail clipper until the nail clippings have been ejected through the space between the cutting edges and downward into the waste basket. If desired, an additional amount of a plastic, a spring or other elastomeric material may be included where desired to provide additional force to help urge the nail clipper from the closed position into the open position or to provide a different feel or appearance. The cutting edges of the blades can be straight or they can include a curvature, as desired. Any preferred cross-sectional profile can be included for the cutting edges. Other possible variations for the nail clipper are described including a method for customization. As desired and briefly mentioned above, the frame of the nail clipper can be molded to include a one-piece construction for the upper and lower frame members. Alternately, the frame can be molded to include two pieces, with a first piece forming the upper frame member and a second piece forming the lower frame member. If the nail clipper includes a two-piece frame, a distal end of the first piece is secured to a distal end of the second piece by any preferred means, including the use of a fastener or a retaining clip, or by any other preferred means, such as by fusing or welding or by the use of an adhesive or combination, thereof. Certain versions of the invention that include an axially pivoting lever that can be used in place of the type of lever that cooperates with the center rod are shown and described.

If the customized nail clippers are manufactured specifically for the user, it is possible to use a frame of the modified dual parallel opposing blade embedded member nail clipper 10a (or any other preferred embodiment whether a single blade or a dual blade version) for insertion therein of whichever one (for single blade versions) of the safety blades 2300, 2300a, 2300b (or any other desired blade 12, 14, 52, 54) that includes a radius of cut which best approximates the desired radius 3008, 3012 or for insertion of two (for dual blade versions) of the same radius safety blades 2300, 2300a, 2300b (or two of any other desired blade 12, 14, 52, 54) that both include a radius of cut which best approximates the desired radius 3008, 3012.

[0255] The nail clipper 10, is shown specifically in FIGS. 1-17, 29 and 36. FIGS. 29, 33 and 36 disclose closely related modifications of the nail clipper 10. Please refer forward and back to review all of the FIGURES and their associated detailed descriptions when considering each embodiment disclosed, herein, as the teachings of each can be selectively modified for use, as desired, with other disclosed forms (i.e., other embodiments) of the invention.

[0256] The nail clipper 10 includes a one-piece frame, identified in general by the reference numeral 16. The frame 16 minimally includes the upper frame member 20 and the lower frame member 18 that are either joined together at a respective distal end 20a, 18a of the upper and lower frame members 20, 18 by molding, fusion, welding or by any preferred method to form a one-piece version of the frame 16. The distal ends 20a, 18a of the upper and lower frame members 20, 18 can be attached to each other or, as shown, they can each be attached to a common rear member. As shown for the nail clipper 10, the distal ends 20a, 18a of the upper and lower frame members 20, 18 are attached to a generally vertical rear wall 19. Alternately, the upper frame member 20 and the lower frame member 18 are manufactured as separate component parts that are fastened and secured together at their respective distal ends 20a, 18a by any preferred method, such as by use of an adhesive or fastener, as is described in greater detail, hereinafter. The frame 16 (whether of one-piece or two-piece construction) may optionally include the vertical rear wall 19 or any desired modification, thereof. If included, the vertical rear wall 19 may be used to elevate the distal end 20a of the upper frame member 20 with respect to the distal end 18a of the lower frame member 18 and/or the vertical rear wall 19 may be used as part of a perimeter of an optional preferred container structure, as is described in greater detail, hereinafter. The vertical rear wall 19 includes an exterior surface visible from the outside of the nail clipper 10 and it also includes an interior rear wall surface 19a, as shown in FIGS. 2 and 3. As used herein, reference to the “rear wall 19” or “vertical rear wall 19” includes any portion, thereof including, as appropriate, the visible exterior surface and/or the interior rear wall surface 19a including possible modifications, made thereto.

[0257] The frame 16 is formed substantially (i.e., more than 50%) of a desired grade of plastic or other polymer, nylon, synthetic, thermoplastic, thermoplastic rubber, or composite material, or of any other preferred non-metallic material or combination of materials. Ideally, all of the frame 16 is formed of a plastic or other non-metallic material with the exception of the horizontal portion 30 of the blades 12, 14 (52, 54) or with the exception of any embedded discreet members, or with the exception of an embedded horizontal portion of a modified embedded member blade, as are described in greater detail, hereinafter. For example, the frame 16 could be formed of a plastic or composite material and any desired portion of the frame 16 could be covered with another material, for example, with a rubber or other elastomeric material. Alternately, the frame 16 could be formed of nylon and any desired portion of the frame 16 could be covered with another material, for example, with a rubber or other elastomeric material. As described below, the frame 16 is fabricated using a minimum amount of metal, however, the frame 16 is always fabricated so that a majority of the frame includes a non-metallic material. As used herein, the general terms plastic and polymer are used interchangeably and are intended to encompass any desired chemically related material.

[0258] The use of selected metal components is, however, anticipated to augment function and durability of the nail clipper 10. An important aspect of the invention includes a novel design for the blades 12, 14, 52, 54 which are preferably formed of a metal such as hardened steel that is also used to increase stiffness and strength of the frame 16 at a critical location. This is described in greater detail, below.

[0259] The upper and lower blades 12, 14 are preferably formed of a metal, such as steel or other alloy. However, the blades 12, 14 (or any variation of the blades 12, 14 as disclosed, herein) can be formed of any suitable material, such as being formed of a ceramic material or formed of any other sufficiently hard material that is also sufficiently strong and durable.

[0260] The horizontal blade portion, identified by bracket 30, and hereinafter referred to as “the horizontal portion 30” or “the horizontal portions 30”, as shown in FIG. 2 and FIG. 11, of the upper and lower blade 12, 14 is embedded in the upper and lower frame members 20, 18, respectively. It is a design variable, within certain limits discussed herein, as to how much of the upper and lower blades 12, 14 are to be utilized as the horizontal portions 30. In other words, either more or less of horizontal portion 30 of the blades 12, 14 can be embedded in the upper and lower frame members 20, 18. Generally, as much of the horizontal portion 30 is embedded into the upper and lower frame members 20, 18 as is possible. This maintains the upper cutting edge 12a of the upper blade 12 and the lower cutting edge 14a of the lower blade 14 as close as possible to the respective upper and lower frame members 20, 18 which decreases stress experienced by the upper and lower frame members 20, 18 during cutting by decreasing a length of a moment arm that extends forward, out from the upper and lower frame members 20, 18 to the cutting edges 12a, 14a.

[0261] The horizontal portions 30 are embedded sufficiently far into at least one of the upper and lower frame members 20, 18 to ensure that the forces experienced when cutting the nail 8 (FIGS. 3 and 4) are applied over or under the horizontal portions 30, or the use of one or more embedded discreet members or use of the modified embedded member blade or the use of sidewalls is required to provide sufficient stiffening for the frame member. These alternative solutions are further described, below.

[0262] In summary thus far, the horizontal portion 30 of each of the blades 12, 14 includes a horizontal plane that is disposed at an angle with respect to a more vertical plane, as shown by bracket 12g, 14g (See FIGS. 11, 11A and 15) that passes through the cutting edges 12a, 14a of the blades 12, 14, and wherein as much as possible of the horizontal portion 30 of each of the blades 12, 14 is embedded in the frame 16 of the nail clipper 10, and wherein the frame 16 is formed substantially of a plastic or other non-metallic material or combination of mostly non-metallic materials, and wherein the horizontal portion 30 includes a length that is sufficient to ensure that a portion of the horizontal portion 30 of each blade 12, 14 that is embedded in the frame 16 is disposed under or over (i.e., in vertical alignment with) any force that is applied to the frame 16 of the nail clipper 10 during cutting of the nail 8 for at least one of the frame members 20, 18, and preferably for both of the frame members 20, 18. This combination of novel elements, arranged as described herein, provides benefits and advantages that are not available with prior art dual parallel opposing blade types of nail clippers (not shown).

[0263] As previously mentioned, it is generally preferred to embed as much of the blades 12, 14 in the upper and lower frame members 20, 18 as possible to improve durability and to have as little of the blades 12, 14 protruding forward and out of the front end 20b of the upper frame member 20 and/or out of the front end 18b of the lower frame member 18, as possible. If an excessive amount of the blades 12, 14 were permitted to protrude forward and out of the front end 20b of the upper frame member 20 and/or out of the front end 18b of the lower frame member 18 then, during use, the protruding portions would act as a lever arm (i.e., the moment arm) that would increase a magnitude of force, by way of mechanical advantage, that is experienced by the plastic of the upper and lower frame members 20, 18 at the area where the blades 12, 14 protrude out of the front end 20b of the upper frame member 20 and/or out of the front end 18b of the lower frame member 18.

[0264] The greater the length of protrusion of the blades 12, 14 out of the front ends 20b, 18b of the upper and lower frame members 20, 18, the greater the length of the moment arm which would, in turn, proportionally increase the magnitude of force experienced by the plastic of the upper and lower frame members 20, 18 proximate the front end 20b of the upper frame member 20 or proximate the front end 18b of the lower frame member 18. As the force experienced increases, there is increasing risk that, during cutting of the nail 8 (See FIG. 3), the blades 12, 14 could fracture the plastic above the front end 20b of the upper frame member 20 or below the front end 18b of the lower frame member 18. Therefore in order to minimize such risk, it is desirable to embed as much of each of the blades 12, 14, as possible, in the upper and lower frame members 20, 18 which minimizes the overall length of the inherent moment arm that occurs which, in turn, minimizes the magnitude of force experienced by the plastic and the risk of damage occurring to the plastic proximate the front end 20b of the upper frame member 20 or proximate the front end 18b of the lower frame member 18.

[0265] As mentioned above and as described in greater detail hereinafter, the upper and lower blades 12, 14 are embedded in the upper and lower frame members 20, 18 of the frame 16 during manufacture of the frame 16 or, if preferred, they can each be inserted (i.e., urged) into a respective upper opening 13a and a lower opening 13b (See FIG. 33) that are provided at the front ends 20b, 18b of each of the upper and lower frame members 20, 18 after the frame 16 has been formed by injection molding or by any other molding technique.

[0266] With further regard to a consideration of the horizontal portion 30, refer momentarily also to FIG. 15 in which the horizontal portion 30 is shown as also being included with the pair of modified blades 52, 54. The modified blades 52, 54 each include a curved contour and a corresponding curved modified cutting edge 52a, 54a. The modified blades 52, 54 are described in greater detail, hereinafter.

[0267] The horizontal portion 30 of the modified blades 52, 54, in a manner identical to that of the horizontal portion 30 of the blades 12, 14, are embedded into the upper and lower frame members 20, 18 by molding or by otherwise forming or manufacturing an integral assembly that includes the horizontal portion 30 of the blades 12, 14 or the horizontal portion 30 of the modified blades 52, 54 in the upper and lower frame members 20, 18 or by later insertion.

[0268] As briefly mentioned above, the horizontal portion 30 of each of the blades 12, 14 or the horizontal portion 30 of each of the modified blades 52, 54 can alternately be embedded into the upper and lower frame members 20, 18 by urging the horizontal portion 30 into the upper opening 13a (FIG. 33) that is provided at the front end 20b of the upper frame member 20 or by urging the horizontal portion 30 into the lower opening 13b that is provided at the front end 18b of the lower frame member 18. If the upper and lower openings 13a, 13b are properly sized, by using sufficient force, the horizontal portion 30 of each blade 12, 14 (or each modified blade 52, 54) are embedded in the upper and lower openings 13a, 13b and are held in place by friction.

[0269] When the horizontal portion 30 of the blades 12, 14 (or the modified blades 52, 54) are fully inserted in the upper and lower openings 13a, 13b, the cutting edges 12a, 14a (or the modified cutting edges 52a, 54a) of the nail clipper 10 oppose each other and are parallel with respect to one-another and the cutting edges 12a, 14a (or the modified cutting edges 52a, 54a) are preferably disposed in a vertical alignment with respect to one-another.

[0270] Whether the blades 12, 14 or the modified blades 52, 54 are utilized, they are always used in corresponding pairs. Preferably to lower cost, the upper blade 12 and the lower blade 14 as well as the upper modified blade 52 and the lower modified blade 54 are identical in construction. During manufacture, the lower blade 14 (or the lower modified blade 54) is inverted in its position with respect to the upper blade 12 (or with respect to the upper modified blade 52).

[0271] As a point of understanding, a blade portion of all prior art steel-framed dual parallel opposing blade types of nail clippers include the cutting edge and a remainder of the blade that is disposed on the same general vertical plane or nearly vertical plane as the prior art cutting edge is disposed. The blade portion of an upper blade of the prior art steel-framed dual parallel opposing blade type of nail clipper descends downward from a front end of the upper steel frame member. The blade portion of a lower blade of the prior art steel-framed dual parallel opposing blade type of nail clipper descends upward from a front end of a lower steel frame member. Therefore, a fulcrum of a lever of a prior art steel-framed dual parallel opposing blade type of nail clipper applies a force during use to a portion of the steel frame of the prior art nail clipper. Accordingly, the horizontal portion 30, as disclosed herein, is a new element not previously known for a blade of a prior art dual parallel opposing blade type of nail clipper. The horizontal portion 30 is an improvement to the blade 12, 14 or to the modified blade 52, 54 that, when embedded in the respective frame members 20, 18 provide significant advantages and benefits not previously available by the prior art devices.

[0272] If preferred, differences in structure may exist between the upper and lower blades 12, 14 or between the upper and lower modified blades 52, 54 whereby they would not be identical, however, they would still be similar-enough to cooperate sufficiently with one-another to function. What is crucial is that the cutting edges 12a, 14a of the blades 12, 14 or the modified cutting edges 52a, 54a of the modified blades 52, 54 correspond sufficiently in size and contour with one-another for any version of the nail clipper 10 to permit the nail clipper 10 to function properly. In general, the cutting edges 12a, 14a and the modified cutting edges 52a, 54a of each pair of upper and lower blades 12, 14 or each pair of modified upper and lower blades 52, 54 cooperate with one-another during use. The upper cutting edge 12a of the upper blade 12 is parallel with respect to the lower cutting edge 14a of the lower blade 14. Similarly, the upper modified cutting edge 52a of the modified upper blade 52 is parallel with respect to the lower modified cutting edge 54a of the lower modified blade 54. Alignment of the cutting edges 12a, 14a, or alignment of the modified cutting edges 52a, 54a, is described in greater detail, hereinafter.

[0273] Continuing with reference on occasion to FIG. 1 while also continuing reference to FIGS. 2-20, 29, and 36, the vertical rear wall 19 is attached to and connects the lower frame member 18 to the upper frame member 20 at the lower distal end 18a of the lower frame member 18 and at the upper distal end 20a of the upper frame member 20.

[0274] When the frame 16 is molded, attachment of the lower distal end 18a of the lower frame member 18 to a bottom of the vertical rear wall 19 and attachment of the upper distal end 20a of the upper frame member 20 to top of the vertical rear wall 19 preferably occurs during manufacture by any preferred molding process in which the upper frame member 20, the lower frame member 18 and the vertical rear wall 19 are integrally formed of a single piece of plastic (or other preferred non-metallic material) and the blades 12, 14 (or the modified blades 52, 54) are attached, thereto, during the molding process. If desired, the distal ends 18a, 20a of the lower and upper frame members 18, 20 could be attached later to the vertical rear wall 19 by any preferred method or attached in a manner that eliminates the vertical rear wall 19. This is described in greater detail hereinafter during discussion of a two-piece version of the invention. See also FIG. 27, 27A and FIG. 28, 28A.

[0275] The advantages of attaching the blades 12, 14 (or the modified blades 52, 54) to upper frame member 20 and the lower frame member 18 by molding are additionally described, hereinafter.

[0276] The blades 12, 14 can also be inserted into the openings 13a, 13b (FIG. 33) that are provided in the upper frame member 20 and/or in the lower frame member 18 after molding (manufacture) of the upper frame member 20 and/or the lower frame member 18 has been accomplished, either when utilizing a one-piece construction or a two-piece construction for the frame 16 of the invention. This is described in greater detail, hereinafter.

[0277] Resuming discussion of the nail clipper 10, as shown in FIGS. 1-10 and 29, when the nail clipper 10 is viewed along a cross-sectional side view (not shown) taken along a vertical plane passing through a longitudinal center axis 11 (shown in dashed line, FIG. 1) of the nail clipper 10, the upper frame member 20, the vertical rear wall 19 and the lower frame member 18 of the frame 16, taken together, somewhat resemble an elongated “U-shape” in appearance.

[0278] The general or overall U-shape appearance of the lower and upper frame members 18, 20 and vertical rear wall 19 is not as apparent when viewed from an external side view (i.e., from the outside) of the nail clipper 10 because the preferred embodiment, as shown, includes an optional pair of opposing first and second container sidewalls 18e, 18f that are preferably molded as integral vertically extending component parts of the lower frame member 18. The opposing first and second container sidewalls 18e, 18f obscure (i.e., cover) from view an opposing pair of vertical planar surfaces 20g, 20h of the upper frame member 20. The first and second container sidewalls 18e, 18f also obscure from view the basic shape of the lower frame member 18 when viewed along the vertical plane passing through the center longitudinal axis 11 of the nail clipper 10.

[0279] According to a less-expensive, more basic version of the nail clipper 10 (not shown) that may be produced as desired, the first and second container sidewalls 18e and 18f are eliminated. Doing so would prevent capture of a nail clipping 8a (See FIG. 4) in the nail clipper 10. A failure to capture the nail clipping 8a may be acceptable for certain users if the cost of the more basic version of the nail clipper 10 is sufficiently low. Capture of the nail clipping 8a in the nail clipper 10 is discussed in greater detail, hereinafter. However, if the first and second container sidewalls 18e, 18f were eliminated in the more basic version, the overall U-shape of the upper frame member 20, the vertical rear wall 19 and the lower frame member 18 of the frame 16 would be readily apparent. It is, of course, possible to modify the overall shape of the nail clipper 10. For example, more of an overall V-shape is also possible as are other overall shapes.

[0280] It is, of course, to be understood that many variations in shape are possible for the frame 16 or for any other aspect of the nail clipper 10 that embody the cardinal teachings, herein.

[0281] Additionally, it is possible and anticipated that certain embodiments of the invention will form the upper frame member 20 and the lower frame member 18 out of two pieces that are subsequently fastened together at the distal ends 20a, 18a by any preferred means during manufacture. The distal ends 20a, 18a may be joined together by ultrasonic, thermal, or chemical welding, by use of an adhesive, or by use of a desired type of mechanical fastener(s) (not shown) such as one or more machine screws, rivets, or secured together by one or more retaining clips, or by any other preferred means. See FIG. 27 and FIG. 28 and a description included hereinafter for an example of the modified spring clip nail clipper-700, that includes a preferred two-piece frame 16 design for certain embodiments of the invention (when a two-piece frame 16 design is desired).

[0282] If a two-piece frame 16 embodiment of the invention is utilized, then the vertical rear wall 19 can be modified to include one-half of the vertical rear wall 19 attached to each of the distal ends 20a, 18a of each upper and lower frame member 20, 18 so that, when joined together, the vertical rear wall 19 is provided. Alternately, the vertical rear wall 19 could be included in its entirety on either the upper frame member 20 or, alternately, in its entirety on the lower frame member 18. Another possible variation is to omit the vertical rear wall 19 and modify the distal end 20a of the upper frame member 20 and/or the distal end 18a of the lower frame member 18 so that, when the upper frame member 20 and the lower frame member 18 are joined (fastened) together, a desired spaced-apart (when not cutting the nail 8) positioning of the front end 20b of the upper frame member 20 with respect to the front end 18b of the lower frame member 18 occurs when the further modified invention is disposed in an open position. As such, use of the vertical rear wall 19 is not necessary for all embodiments of the invention. What is essential is to provide the necessary spaced-apart positioning of the cutting edges 12a, 14a (or modified cutting edges 52a, 54a) when the nail clipper 10 (or any embodiment, thereof) is disposed in the open position. The desired spaced-apart positioning of the nail clipper 10 in the open position is shown in FIGS. 1, 3, and 6. An example of forming a modified type of an upper frame member and a modified type of a lower frame member out of two pieces that are secured (i.e., fastened) together at a distal end, thereof, is shown in FIGS. 27 and 28 and is further discussed, hereinafter. If sidewalls 18e, 18f are included, as discussed below, it is preferable but not necessary to include the vertical rear wall 19 and attach a distal end of each of the sidewalls 18e, 18f to the rear wall 19.

[0283] If desired, a modified embodiment that includes a one-piece modified frame (not shown) could also eliminate the rear wall 19 of the nail clipper 10, as preferred. The desired spaced-apart positioning of the front end 20b of the upper frame member 20 with respect to the front end 18b of the lower frame member 18 could be provided by the overall shape of the molded one-piece modified frame. For example, see FIG. 1 of currently co-pending patent application Ser. No. 13/385,701, entitled, “Nail Clipper with Opposing Parallel Blades,” that was filed on Mar. 1, 2012 as being illustrative of an example of a one-piece modified frame design that includes a curved continuous structure at a distal end, thereof, and which could be further modified to include the essential structural attributes and cardinal teachings of the current invention. The continuously curving structure would eliminate the need to include the vertical rear wall 19 of the nail clipper 10 at the distal ends 18a, 20a.

[0284] The preceding examples and all variations mentioned or described herein or included herein by way of reference illustrate alternate ways of bringing forth the current invention (i.e., different shapes and/or different options for construction of the frame 16 including frames that include either one and/or two-piece variations, thereof), and are intended to further illustrate that while a few possible preferred embodiments are shown and described herein, that other modifications and/or changes are possible. The use of plastic to form the greater part of the frame 16 (or any variation/or modification of the frame 16) is what provides a virtually unlimited range of new, previously unavailable design possibilities.

[0285] The cardinal teachings disclosed herein permit the structural use of plastic for the frame members 20, 18 (as opposed to the requirement to use steel for the prior art frame (not shown) of prior art devices). The structural use of plastic, as disclosed herein, to form the frame members 20, 18 in turn allows for many of the other benefits and advantages of the nail clipper 10 (or other embodiments, thereof) that are not available with the prior art devices. Accordingly, the invention is not limited to the examples shown herein but is defined by the scope of the claims, as later appended, hereto.

[0286] Preferably, the frame 16, including the upper frame member 20, the vertical rear wall 19 and the lower frame member 18 are formed by molding these component parts substantially (i.e., over 50% of the frame 16) from a plastic (i.e., any desired polymer) or from any other preferred non-metallic material. This is preferred whether the frame 16 is formed as a one-piece assembly or if the upper frame member 20 and the lower frame member 18 are modified and formed as two separate pieces that are then fastened together. As mentioned before, as much of the frame 16, as possible, are formed of the plastic (or other non-metallic material).

[0287] Any molding technique is available for use with any embodiment of the invention to manufacture any of the component parts that are substantially formed of plastic or of another non-metallic material or combination of materials. If desired, any of the plastic or non-metallic component parts can alternately be formed by cutting, grinding, or otherwise removing unwanted material from a larger block of material or by any other desired manufacturing technique or method of fabrication, including, for example, but in no way limited to the use of layering or other techniques or methods of polymer fabrication that are generally referred to as “3-D printing” technologies.

[0288] For additional examples of possible two-piece modified frames that could be further modified for use with the current invention, please see related presently co-pending patent application Ser. No. 13/385,701 noted above, wherein the entire content of the above-identified co-pending patent application is included herein by way of reference. In particular, please refer to FIGS. 4 and 8 of the above-referenced co-pending patent application.

[0289] Returning to FIG. 1 of the current invention, the frame 16 can be molded using any desired type of plastic or polymer or it can be formed primarily from any other desired non-metallic material including any preferred type of composite non-metallic material. It is to be understood that while the frame 16 is molded or otherwise formed substantially (more than 50%) of a non-metallic material, the frame 16, or any other component part of the nail clipper 10, can include the use of metal for reinforcing or attaching purposes. However, the frame 16 of the nail clipper 10 is not formed primarily of a metal.

[0290] For example, the frame 16, while formed primarily of a non-metallic material, may include one or more metallic members embedded or molded therein. Typically such a member or members, if included, are used to stiffen or otherwise reinforce or strengthen some portion of the frame 16 of the nail clipper 10. Such use of a very small amount of metal (in a predominantly plastic frame 16 is different than what is known, taught or suggested by the relevant prior art that appertains to the prior art dual parallel opposing blade types of nail clippers.

[0291] The horizontal portion 30 of the blades 12, 14 is an example of a metallic element that is embedded into the frame 16. The horizontal portion 30 provides numerous advantages. The horizontal portion 30 stiffens, reinforces and/or strengthens this portion of the frame 16 (i.e., a forward area proximate the front end 20b of the upper frame member 20 and proximate the front end 18b of the lower frame member 18 that includes the horizontal portion 30 embedded, therein.) The horizontal portion 30 also significantly changes the way in which a pair of opposing cutting forces are applied to the frame 16 (as compared to all prior art dual parallel opposing blade types of nail clippers with dual parallel opposing cutting blades) and, additionally, the horizontal portion 30 significantly changes the manner by which the cutting forces are transferred through the frame 16 to the blades 12, 14 and, finally, to the upper and lower cutting edges 12a, 14a.

[0292] Current placement of the horizontal portion 30 of the blades 12, 14 in the front end 20b of the upper frame member 20 and in the front end 18b of the lower frame member 18 reduces the amount of shear force that is applied to, and experienced by the frame 16 by replacing shear force with a compressive force. This is a substantial improvement in design that permits the inexpensive use of plastic, rather than steel, in construction of the frame 16 of the nail clipper 10, resulting in a durable and an aesthetically improved device appearance.

[0293] To better understand the improvement provided by the horizontal portions 30, a contrasting example is now provided that includes making a proposed modification to a prior art type of relevant device. By way of contrast with the prior art, excessive shear force would occur if a modification of a prior art type of a steel-frame dual parallel opposing blade type of nail clipper (not shown) with dual parallel opposing cutting blades that included a steel frame structure and steel parallel opposing blades included only replacing the steel frame of the prior art all-steel dual parallel opposing blade nail clipper with a plastic frame to provide a modified plastic frame for the steel-frame prior art device. It is understood that the prior art device could, of course, also include non-metallic coverings or accessories, as desired, understanding that the all-steel frame is used for the transfer of cutting forces during use. The substitution of a plastic frame for the steel frame would not anticipate the current invention or the benefits provided by the nail clipper 10. The use (i.e., cutting) of the proposed modified plastic frame nail clipper would require depressing a lever included with the prior art nail clipper, the lever being identically disposed on the modified plastic frame as compared to where the lever was disposed when the frame (of the prior art device) was made of steel. Therefore, the lever of the proposed modified plastic frame would apply the force along a longitudinal length of the frame during cutting. Force would not be applied specifically or directly over or directly under or directly to any portion of the blade. The cutting force would be applied to the frame along the length of the unreinforced modified plastic frame, at the same locations along the frame as where the force is applied to the prior art steel-framed device.

[0294] Before concluding consideration of the efficacy of the proposed modified plastic frame, let us momentarily review how operation occurs with the prior steel frame device during use. The force produced by the lever is experienced by the steel frame as a downward force applied on top of the steel frame that is caused by downward pressure applied to the top of the steel frame by the lever and as an opposing upward force applied to bottom of the steel frame by a steel center rod that is simultaneously urging a bottom of the steel frame upward which prevents the bottom of the steel frame from being urged further downward. All of the force during cutting is applied to the steel frame of the prior-art device. The steel frame must then transfer the cutting force to the integrally formed (or detachable) parallel steel blades and ultimately to the cutting edges of the blades. Resistance of the nail (not shown with a prior art device) applies a resistive force that is opposite in direction to the direction of movement of the cutting edges during cutting of the nail. The resistive force is also opposite to the direction of the applied cutting forces. The difference between the direction of the resistive force and the direction of the cutting force produces an area of shear along a portion of the steel frame between where the blade begins and where the cutting force is applied. Because steel is sufficiently strong, the amount of shear experienced does not cause damage to the steel frame. Sufficient cutting force is applied through the area of shear and to the blades to sever the nail.

[0295] Returning to the consideration of the efficacy of the proposed modified plastic frame, plastic cannot withstand this level of shear. Therefore, if the previously noted cutting forces are applied to the proposed modified plastic frame (of this example which proposes substitution of the steel prior art frame with a plastic frame), excessive shear (also referred to as shear force) would occur between the beginning of the (steel) blades and where the cutting force is applied to the plastic frame of the proposed modified prior art device. The excessive level of shear would distort the frame, bending and/or damaging it. Therefore, inherent structural limitations preclude substitution of plastic for the steel frame of the prior-art all-steel dual parallel opposing blade nail clipper. In summary, this is because the forces that would be applied to the modified plastic frame would then have to be transferred through the plastic frame to the blades of the modified prior art nail clipper. This transfer of cutting forces would result in an excessive amount of shear occurring at an area of intersection between the plastic frame and a beginning of the blades. This, in turn would render the resultant device inoperative.

[0296] It is noted that the use of plastic for the structural members that include opposing blades of a dual parallel blade nail clipper is not previously known outside (i.e., before) the earliest priority date of the parental patent lineage (i.e., ancestry) of the current invention (beginning with currently pending application Ser. No. 11/305,561 that was filed on Dec. 15, 2005).

[0297] As discussed herein, the nail clipper's 10 use of the embedded horizontal portion 30 in plastic provides several important and unexpected benefits that allow the nail clipper 10 to function reliably and which permit manufacture at exceptionally low cost while also increasing eye-appeal (i.e., aesthetic attractiveness), durability, ergonomics, texture, utility and improving the way the nail clipper 10 feels during use.

[0298] The application of cutting forces, as applied to the nail clipper 10, when cutting the nail 8 (FIG. 3) is described in greater detail, hereinafter.

[0299] As a further example of the use of metal during manufacture of the nail clipper 10, any component part of the nail clipper 10 other than the frame 16 as described above (i.e., excluding the upper frame member 20, the vertical rear wall 19 (if included) and the lower frame member 18) can be formed partially, substantially, or entirely of metal or, alternately, partially, substantially, or entirely of plastic (or any other non-metallic material), as desired. Such specific use of metal with the nail clipper 10 (or any version thereof) is possible while keeping in mind that it is also a general object of the invention to reduce the use of metal in an parallel opposing dual blade type of nail clipper whenever possible and, if possible, to eliminate the use of metal entirely from certain of the component parts. However, this general objective does not prevent or preclude the manufacture of certain component parts of the nail clipper 10 largely or entirely from metal (other than the upper frame member 20, vertical rear wall 19 and the lower frame member 18 (i.e., the frame 16), which is/are substantially comprised (formed) of a non-metallic material). In general, metal is used in the nail clipper 10 when the use of a metal provides a benefit or advantage in terms of cost, manufacture, aesthetics, utility, durability, consumer preference and/or a structural advantage.

[0300] For example if desired, the lever 32 (FIG. 1) can be formed entirely or substantially of any preferred metal or alloy. However, it is generally preferred, as noted above, to form the lever 32 substantially or even entirely from a plastic, or from a composite material or from another non-metallic material, whenever possible.

[0301] Accordingly, the use of the reinforcing embedded member 32b that is embedded in the plastic (non-metallic) lever 32 is clearly anticipated by this disclosure, as shown in FIG. 22 and FIG. 25 (where the embedded reinforcing elongated member 32j is shown) to stiffen, reinforce and/or strengthen the lever 32, as desired. Similarly, the pin 34 (As shown in FIGS. 1, 3-10, 12, 13, 18-21, 26-28, 30, 32; 32A, 34, 36, 50-53, and 58A-58B) can be formed of a metal or formed of an alloy. Any preferred sufficiently strong non-metallic material can also be used to form the pin 34. Similarly, the lever 32 or the center rod 24 (FIG. 12) or the modified two-piece center rod 124 (FIG. 13), as preferred, can be formed of a metal or formed of an alloy or, alternately, formed of any preferred non-metallic material providing the material used to form the pin 34 and/or the lever 32 and/or the center rod 24 or the modified two-piece center rod 124 is sufficiently strong and durable. See also FIGS. 22, 24 and 25 and a later description regarding these drawings for additional possible modifications to the lever 32.

[0302] Additionally as mentioned herein, a metal fastener (for example, a machine screw and nut (not shown)) or clip can be included to secure the upper and lower members 20, 18 of a two-piece embodiment of the invention together. The screw, nut or clip can be formed of plastic, nylon or a preferred metal. As an example, refer momentarily to FIGS. 27 and 28 where the modified spring clip nail clipper 700 is shown that includes a spring clip 702. The spring clip 702 is formed of any preferred material. The use of a metal to form the spring clip 702 may be preferred to minimize the cost of manufacture and to increase a force that is applied to a modified spring clip frame, identified in general by the reference numeral 716, of the modified spring clip nail clipper 700. The force supplied by the spring clip 702 is described in greater detail, hereinafter.

[0303] Similarly, the modified spring clip frame 716 or the frame 16 can be molded using any desired color or type of plastic. For example, a pink color of the modified spring clip frame 716 or the frame 16 may appeal to girls and women whereas another color, such as blue or green, may be more likely to appeal to boys and men. Multiple colorings are possible for inclusion with any version of the nail clipper 10, as well as the inclusion of logos, lettering and numerous other possible aesthetic modifications. If included with the nail clipper 10, the logos, lettering and other aesthetic modifications can include raised and/or recessed lettering or symbols. It is also possible to fabricate multiple portions of the modified spring clip frame 716 of the modified spring clip nail clipper 700 or the frame 16 of the nail clipper 10 utilizing two or more different polymers, or two or more different non-metallic materials if an aesthetic or structural advantage or a desired “feel” is derived from doing so. Please refer to co-pending patent application Ser. No. 13/385,701 for additional discussion regarding the advantages and versatility derived from the use of one or more polymers for the frame of a dual parallel opposing blade type of nail clipper.

[0304] What is especially important to appreciate is that the design of the nail clipper 10 (including any embodiment, thereof), unlike prior art dual parallel opposing blade types of nail clippers (not shown), relies very little on the inherent mechanical strength and stiffness of the frame 16 to transfer force during use (i.e., during cutting of the nail 8) to the pair of opposing blades 12, 14 because the design of the nail clipper 10 significantly reduces shear in the frame 16. Please refer, in particular, to FIGS. 1-5, 9-11, 15, and 18-33, 36 and the following discussions that appertain to these FIGURE drawings. This is of significant importance because the novel transfer of force provided by the nail clipper 10 and any embodiment, thereof, allows the frame 16 (or any modification made to the frame 16, thereof) to be substantially (i.e., greater than 50%) formed of plastic (i.e., polymer) or from another non-metallic material and, in certain embodiments the frame 16 (or any modification made to the frame 16, thereof) the design of the nail clipper 10 allows the frame 16 to be fabricated/formed of a lesser grade of plastic or possibly utilizing another non-metallic material than would otherwise be suitable for use.

[0305] An appreciation of the forces and stress involved is useful in understanding the advantages and benefits of the nail clipper 10. The nail clipper 10 is being used to illustrate the stresses and forces that occur when cutting the nail 8 using the nail clipper 10 or which similarly occur when using any steel-framed prior art type of dual parallel opposing blade type of nail clipper.

[0306] When using any prior art dual parallel opposing blade type of nail clipper or when using the nail clipper 10 or any embodiment, thereof, it is important to appreciate that significant force and stress is applied to and experienced by the nail clipper 10 during actual cutting of a portion of the nail 8. This is because the cut through the nail 8 is occurring simultaneously across an entire length of the nail 8 that is disposed between the cutting edges 12a, 14a (or the modified cutting edges 52a, 54a) and because it is occurring simultaneously on both sides of the nail 8. Please refer momentarily to FIG. 14 where a cross-sectional view illustrates six of many possible profiles that are available for the cutting edges 12a, 14a. Please refer also to FIG. 3.

[0307] As each cutting edge 12a, 14a is progressively urged deeper into the nail 8 during cutting of the nail 8, a progressive increase in a thickness of the blade 12, 14 proximate the cutting edge 12a, 14a is also occurring. Increasing thickness of the blade 12, 14 increases resistance to the cut as the cut progresses through the nail 8. As noted above, the resistance is experienced as an opposing resistive force experienced by the blades 12, 14 that occurs in a direction opposite to the direction that the blades 12, 14 are each, respectively, being urged.

[0308] This is because a portion of the force applied to the nail 8 by the blades 12, 14 is experienced by the nail 8 as a horizontal force vector applied to the nail 8 and offset approximately ninety degrees from a primary force, or vertical vector applied to the nail 8 occurring along the vertical plane of cut (i.e., urging the cutting edges 12a, 14a toward one-another). The cross-section profile of the cutting edges 12a, 14a (See also FIG. 14) significantly influences the magnitude of the horizontal force vector applied to the nail 8. The horizontal force vector applied to the nail 8 is attempting to urge the nail clipping 8a away from a remaining portion of the nail 8, which the nail 8 continues to resist until the cut through the nail 8 is nearly complete or has been completed. The magnitude of the horizontal force vector applied to the nail 8 increases as the depth of cut into the nail 8 increases in response to the progressive increase in the thickness of the blades 12, 14. Again, this is simultaneously occurring on both sides of the nail 8.

[0309] As the width of the blades 12, 14 entering into the nail 8 and the horizontal force vector applied to the nail 8 are both simultaneously increasing, these forces are experienced by the nail clipper 10 as a progressive increasing in resistance (i.e., a resistive force opposing the direction of cut) consistent with Newton's third law of motion, “for every action there is an equal and opposite reaction.” The increasing resistance results in an opposing force vector that represents the resistive force. The opposing force vector includes an upper and a lower opposing force vector that are each experienced by the blades 12, 14 in a direction that is opposite that of the primary force vectors that are applied to a top planar surface 20d of the upper frame member 20 and simultaneously to a bottom planar surface 18c of the lower frame member 18, and which are then transferred to the blades 12, 14 and to the cutting edges 12a, 14a of the blades 12, 14. Increasing resistive force demands that an even greater cutting force is applied to the frame 16 of the nail clipper 10 by increasing a downward force that is applied to the lever 32 of the nail clipper 10. This urges the blades 12, 14 deeper into the nail 8 which further increases the magnitude of the resistive force.

[0310] Therefore, the primary force vectors during cutting are experienced by the frame 16 of the nail clipper 10 substantially as a first compressive force attempting to urge the plastic on top of the horizontal portion 30 of the upper frame member 20 in a downward direction toward the horizontal portion 30 of the upper blade 12, and as a second compressive force attempting to urge the plastic below the horizontal portion 30 of the lower frame member 18 in an upward direction toward the horizontal portion 30 of the lower blade 14. By design, these first and second compressive forces occur along the length of the upper and lower frame members 20, 18 that also include the horizontal portions 30 embedded, therein. A small amount of shear may occur along the longitudinal length of the horizontal portions 30; however shear experienced by any portion of the upper and/or lower frame members 20, 18 is minimal and the greater portion of the minimal shear that is experienced is confined to the portion of the upper and lower frame members 20, 18 that also include the horizontal portions 30 embedded, therein, and which are thereby easily able to accommodate the small amount of shear that is experienced. The amount of shear experienced is a small fraction of the magnitude of shear that would be experienced by the frame 16 if the cutting forces were instead applied to the upper and lower frame members 20, 18 at a location that did not include the embedded horizontal portions 30.

[0311] The opposing resistive forces continue to increase until the cut is finished (or very nearly finished), at which point the nail clipping 8a is forcibly ejected from a remaining portion of the nail 8 in the direction of arrow 43 (FIG. 4). The stress that occurs in the prior art dual parallel opposing blade type of nail clipper during cutting of the nail 8 results in progressively increasing shear force occurring within the frame of the prior art nail clipper, as earlier described. The preceding additional discussion further illustrates, consistent with earlier discussions, why the mere substitution of the proposed modified plastic frame for the steel frame of the prior art dual parallel opposing blade type of nail clipper will result in excessive stress occurring within the proposed modified plastic frame.

[0312] As briefly discussed above, because of the horizontal portion 30 embedded in the nail clipper 10, the force applied is primarily experienced by the nail clipper 10 as the first compressive force that is applied in a downward first direction by the fulcrum 33 (See FIGS. 1 and 4) of the lever 32 to the top planar surface 20d of the upper frame member 20 proximate the front end 20b of the upper frame member 20 and simultaneously as the second compressive force that is applied in an opposite upward second direction (as compared to the first force) to the bottom planar surface 18c of the lower frame member 18 proximate the front end 18b of the lower frame member 18.

[0313] Certain embodiments described herein apply the first compressive force and the second compressive force to a different portion (location) as described, herein, however all embodiments include the embedded (or a partially embedded) horizontal portion 30 and the resulting application of both the first and second compressive forces to occur in vertical alignment with (i.e., over or under) each of the respective horizontal portions 30 of the blades 12, 14.

[0314] This novel arrangement in structure is satisfied specifically, by including an approximate ninety degree bend in the blades 12, 14, and by extending the horizontal portion 30 of the blades 12, 14 a sufficient amount, and by embedding the horizontal portions 30 a sufficient amount into the front ends 20b, 18b of the upper and lower frame members 20, 18, and by ensuring that the application of cutting forces applied to the frame members 18, 20 occurs over the horizontal portions 30.

[0315] This novel arrangement in structure is accompanied by a significant reduction in the magnitude of shear force that is experienced by the frame 16 and it also provides the frame 16 with a significantly greater ability to withstand shear as well as compressive force in the areas where the primary cutting forces are applied to the upper and lower members 18, 20 of the frame 16, specifically over or under the horizontal portions 30. This arrangement in structure applies to the nail clipper 10 and any modification, thereto.

[0316] The horizontal portion 30 (Please refer also to FIGS. 2, 11 and 15) of the blades 12, 14, as discussed above, are embedded in the upper and lower frame members 20, 18 in any of a variety of possible described ways. Some of the variation possible is discussed later. The horizontal portion 30 of the blades 12, 14 receives and responds to the first and second compressive forces which are applied in opposite directions to the upper and lower frame members 18, 20 by urging the front end 20b of the upper frame member 20 and the front end 18b of the lower frame member 18 toward each other.

[0317] Plastic is able to withstand substantial compressive force if adequately supported on an opposite side. The horizontal portions 30 provide the support necessary for the plastic to withstand the applied compressive forces as well as any shear that is experienced in this general area (i.e., over or under the horizontal portions 30).

[0318] As the front end 20b of the upper frame member 20 and the front end 18b of the lower frame member 18 are urged toward each other, a remaining portion of the upper and lower frame members 20, 18 (from the end of each of the horizontal portions 30 to the respective distal ends 20a, 18a of the upper and lower frame members 20, 18) are also urged toward each other a proportionate amount until the nail clipper 10 is disposed in the closed position.

[0319] The novel transfer of forces that occur, during cutting, within the nail clipper 10 can perhaps be further understood by considering that as the horizontal portions 30 are each urged toward one-another they, in turn, urge the remaining portion of the upper and lower frame members 20, 18 a necessary amount toward each other. In this manner, a minimal magnitude force is experienced by the remaining portions of the upper and lower frame members 20, 18, and, most importantly, the remaining portion of the upper and lower frame members 20, 18 of the nail clipper 10 (by way of comparative illustration) do not initially receive the cutting forces and then have to transfer the cutting forces through the unreinforced plastic remaining portion of the upper and lower frame members 20, 18 and apply the forces to the blades 12, 14, as occurs with all prior art similar devices that, of necessity, include steel frames. To the contrary, the overwhelming majority of cutting forces are applied directly above and/or below the horizontal portions 30 of the blades 12, 14 of the nail clipper 10.

[0320] Therefore, the blades 12, 14 experience the overwhelming majority of cutting forces. The cutting forces (i.e., the first and second compressive forces) urge the blades 12, 14 toward one-another. As the blades 12, 14 are urged toward each other the blades 12, 14, in turn, urge the remaining portions of the upper and lower frame members 20, 18 toward each other a minimal, yet sufficient amount, until the nail clipper 10 has been urged into the closed position.

[0321] This is the diametric opposite of the prior art approach of applying force directly to the prior art frame members sufficient to urge the prior art frame members toward each other and then relying on the prior art frame members to, in turn, urge the prior art cutting edges of the prior art blades toward each other. The prior art blades include the prior art cutting edges and are on a different plane than the plane of the prior art frame members. The prior art frame members are disposed on a generally horizontal plane while the prior art blades are disposed on a generally vertical plane that is disposed at approximately a ninety-degree angle with respect to the prior art frame members.

[0322] With the nail clipper 10, an increased reliance on compressive force is used to help urge the blades 12, 14 toward one-another. The blades 12, 14 each respectively help urge the frame members 18, 20 toward each other. As the upper and lower frame members 20, 18 are urged toward each other and into the closed position a slight amount of shear is experienced by the remaining portions of the upper and lower frame members 20, 18 (i.e., the remaining portions include that portion of the upper and lower frame members 20, 18 that does not include the horizontal portions 30). However, the amount of shear experienced by the remaining portions of the upper and lower frame members 20, 18 is minimal and can be easily accommodated by the upper and lower frame members 20, 18 without causing damage to the plastic or to any other non-metallic material that may be used to form the majority of the frame 16 structure.

[0323] It is preferred that, except for the horizontal portions 30 that are embedded in the upper and lower frame members 20, 18 and, possibly excluding the center rod 24 and, if included, possibly excluding the spring clip 702 (see FIGS. 27 and 28), that the remainder of the frame 16 is formed of one or more types of polymers and/or one or more types of other non-metallic materials.

[0324] Please refer momentarily now to FIG. 8, which shows the nail clipper 10 disposed in a rest or transit position that provides a thin contour (i.e., minimum volume) for storage or transportation.

[0325] The upper frame member 20 includes an upper segment, identified by bracket 20k of the upper frame member 20 where the upper segment 20k is disposed above the horizontal portion 30 of the upper blade 12, and a lower segment identified by bracket 20m of the upper frame member 20, where the lower segment 20m is disposed under the horizontal portion 30 of the upper blade 12. The overall thickness of the upper frame member 20 at the horizontal portion 30 is the sum of the thickness of the upper segment 20k plus the thickness of the lower segment 20m plus a blade thickness 45 (See bracket 45, FIG. 11) of the horizontal portion 30 of the upper blade 12.

[0326] The lower frame member 18 includes an upper segment of the lower frame member 18, identified by bracket 18k, where the upper segment 18k is disposed above the horizontal portion 30 of the lower blade 14, and a lower segment, identified by bracket 18m, of the upper frame member 20, where the lower segment 18m is disposed under the horizontal portion 30 of the lower blade 14. The overall thickness of the lower frame member 18 at the horizontal portion 30 is the sum of the thickness of the upper segment 18k plus the thickness of the lower segment 18m plus the blade thickness 45 of the horizontal portion 30 of the lower blade 14.

[0327] The downward first compressive force is applied by the fulcrum 33 to the top of the upper segment 20k of the upper frame member 20, transferred downward through the upper segment 20k to the horizontal portion 30 of the upper blade 12. A bottom of the upper segment 20k is above and, thereby, supported by the top blade surface 12f (FIG. 11) of the horizontal portion 30 of the upper blade 12. Therefore, the plastic (or other non-metallic material) used to form the upper segment 20k or any other portion of the upper frame member 20 is not damaged by the downward first compressive force because the downward first compressive force is smoothly transferred through the upper segment 20k and to the upper blade 12.

[0328] The upward second compressive force is applied by an enlarged head 24a of the center rod 24 to the bottom of the lower segment 18m of the lower frame member 18, transferred upward through the lower segment 18m to the horizontal portion 30 of the lower blade 14. A top of the lower segment 18m is supported by a bottom blade surface 14b of the horizontal portion 30 of the lower blade 14. Therefore, the plastic (or other non-metallic material used to form the lower segment 18m) is not damaged by the upward second compressive force because the upward second compressive force is smoothly transferred through the lower segment 18m and to the lower blade 14.

[0329] In this manner the downward first compressive force and the upward second compressive force urge the upper blade 12 and the lower blade 14 toward each other when the lever 32 is depressed with sufficient force. See also FIG. 36. The upward second compressive force can also be seen as sufficient to keep the lower frame member 18 from being urged (i.e., displaced) away from the upper frame member 20 during use. In other words, the lower frame member 18 does not have to be urged upward during use. The upper frame member 20 can do all the movement relative to the lower frame member 18 by flexing downward and upward. Or both the upper frame member 20 and the lower frame member 18 can both flex an equal amount or an unequal amount. As long as either blade (12 or 14) or both blades 12, 14 can be sufficiently urged toward each other from the open position into the closed position and back into the open position, then the nail clipper 10 can function properly.

[0330] As shown in FIG. 1 and FIGS. 6-8, the lower frame member 18 includes the first and second container sidewalls 18e, 18f attached thereto along a longitudinal length of the bottom of the sidewalls 18e, 18f. As the first and second container sidewalls 18e, 18f are also attached to the vertical rear wall 19, this provides considerable stiffness to the lower frame member 18. Therefore, the upper frame member 20 experiences a significantly greater degree of flexing during cutting.

[0331] Therefore, with the nail clipper 10, the upward second compressive force is used primarily to prevent the lower frame member 18 from being urged downward and away from the upper frame member 20 when the lever 32 is depressed during cutting. The stiffening provided to the lower frame member 18 by the optional first and second container sidewalls 18e, 18f significantly increases the resistance of the lower frame member 18 to vertical flexing during use. This results in less reliance upon the horizontal portion 30 in the lower frame member 18 to stiffen and convert a portion of the force applied, thereto, into a compressive force. Accordingly, use of the first and second container sidewalls 18e, 18f may be used in certain embodiments of the invention to eliminate the need for a portion of the horizontal portion 30 of the lower blade 14 to be disposed in vertical alignment with the (upward) force that is applied to the lower frame member 18 during cutting of the nail 8. However, even if the first and second container sidewalls 18e, 18f are included it is generally preferred that the horizontal portion 30 of the lower blade 14 is disposed in vertical alignment with the applied (upward) force.

[0332] Other changes are possible that would allow equal or near equal flexing of both a modified upper frame member and a modified lower frame member with respect to each other, as shown in FIGS. 34 and 35. These embodiments are described in greater detail, hereinafter.

[0333] If it was desired to increase flexing of either the upper or lower frame member 20, 18 an optional flex area 71 (See dashed lines, FIG. 5) could be included across the upper frame member 20 (as shown) proximate the vertical rear wall 19 or elsewhere, as desired. The optional flex area 71 is molded to include less material under the dashed line showing the optional flex area 71 and it, therefore, weakens the upper frame member 20 at this area. If included, the flex area 71 acts as a hinge to aid in flexing the upper frame member 20 about the flex area 71.

[0334] If desired, the flex area 71 could extend only partway across the upper frame member 20 to provide a more resistive (to flexing) hinge. Similarly, the flex area 71 could include different depths across the width of the upper frame member 20. If desired, the above teachings regarding the flex area 71 could alternately be optionally included across the entire or partial width of the lower frame member 18 or across both the lower and upper frame members 18, 20. As shown, the flex area 71 is curved to minimize stress and fatigue; however any preferred shape or variation in shape is possible for the flex area 71, which is optional for various embodiments of the invention.

[0335] Referring also to FIGS. 1, 3, 6, 8, 9, 11 and 12 the placement of the center rod 24 can be understood, as follows. From an upper end 24b of the center rod 24 proceeding downward, the upper end 24b of the center rod 24 is disposed in a U-shaped recessed area 32c of the lever 32. A remainder of the center rod 24 extends downward, through the nail clipper 10. The pin 34, as mentioned above, passes through a pair of aligned pin openings 32d, 32e of the U-shaped recessed area 32c of the lever 32 and through a pin aperture 24c (FIG. 12) of the center rod 24, thereby securing the U-shaped recessed area 32c of the lever 32 to the center rod 24.

[0336] The center rod 24 then passes downward through an upper center rod hole 20n (FIG. 8) that is provided through the upper segment 20k of the upper frame member 20. The center rod 24 continues downward through a center hole 22 (FIG. 11) of the upper blade 12 and through a lower center rod hole 20p (FIG. 8) that is provided through the lower segment 20m of the upper frame member 20. The center rod 24 continues downward through a gap between the upper frame member 20 and the lower frame member 18. The center rod 24 then passes through an upper center rod hole 18n that is provided through the upper segment 18k of the lower frame member 18. The center rod 24 continues downward through the center hole 22 of the lower blade 14 and through a lower center rod hole 18p that is provided through the lower segment 18m of the lower frame member 18. A bottom of the center rod 24 is attached to, and thereby includes, the enlarged head 24a. The upper surface of the enlarged head 24a bears against the bottom planar surface 18c of the lower segment 18m of the lower frame member 18. The center hole 22 is disposed in the horizontal portion 30 of both the upper blade 12 and the lower blade 14.

[0337] The center rod 24 passing through the upper center rod hole 20n, the center hole 22 of the upper blade 12, and the lower center rod hole 20p ensures that the upper frame member 20 maintains alignment with the center longitudinal axis 13 (FIGS. 1 and 12) of the center rod 24 as the upper frame member 20 is urged vertically downward toward the lower frame member 18 or upward and away from the lower frame member 18.

[0338] Similarly, the center rod 24 passing through the upper center rod hole 18n, the center hole 22 of the lower blade 14, and the lower center rod hole 18p ensures that the lower frame member 18 maintains concentric alignment with the center longitudinal axis 13 of the center rod 24 as the lower frame member 18 is urged closer to the upper frame member 20 or further away from the upper frame member 20, regardless of which frame member (20 or 18) is flexing most.

[0339] In this manner, the center rod 24 also helps to maintain vertical alignment between the upper and lower frame members 20, 18 as they move toward or away from each other. This arrangement helps ensure that a significant amount of the cutting force applied to the frame 16 by the fulcrum 33 of the lever 32 (as the downward first compressive force is applied to the upper frame member 20) and by the enlarged head 24a of the center rod 24 (as the upward second compressive force is applied to the lower frame member 18), which occur simultaneously whenever the lever 32 is urged downward in the direction of arrow 50b (FIG. 4) remain as compressive forces. It is desirable to maximize compressive force and minimize shear force that is experienced by the frame 16. By maintaining vertical alignment between the upper and lower members 20, 18 during use, less of the cutting force applied to the nail clipper 10 is experienced as shear force by the frame 16 and a greater proportion of the cutting force is experienced by the frame 16 as the first and second compressive forces.

[0340] As the upper and lower frame members 20, 18 move relative to each-other, the upper surface of the enlarged head 24a maintains contact with the bottom planar surface 18c of the lower segment 18m of the lower frame member 18.

[0341] Also, because the lever 32 is attached to the center rod 24 by the pin 34, upward motion of the upper frame member 20 is limited. FIGS. 1, 3, 6 and 9 are illustrative of the nail clipper 10 disposed in the fully open position. The upper frame member 20 is maximally away from the lower frame member 18 when the (fully assembled) nail clipper 10 is disposed in the open position. This is true after the nail clipper 10 has been fully assembled. Providing increased separation between the upper and lower frame members 20, 18 than is required when the nail clipper 10 is disposed in the open position is described in greater detail, below.

[0342] Conversely, when the cutting edge 12a of the upper blade 12 contacts the cutting edge 14a of the lower blade 14, the nail clipper 10 is disposed in the fully closed position. The upper frame member 20 and the lower frame member 18 are disposed maximally close to each other when the nail clipper 10 is disposed in the closed position. FIGS. 4, 7 and 10 are illustrative of the nail clipper 10 disposed in the closed position.

[0343] The downward first compressive force applied to the nail clipper 10 attempts to compress in a downward direction the plastic of the top planar surface 20d of the upper frame member 20 directly under the fulcrum 33. The downward first compressive force is applied by the fulcrum 33 of the lever 32 to the top planar surface 20d of the upper segment 20k as an upper portion, identified by bracket 32a, (FIG. 1) of the lever 32 is depressed (urged in the downward direction of arrow 50b.)

[0344] Concurrently, as the lever 32 is depressed, the opposite second compressive force is applied in an opposite, or upward direction, to the center rod 24 by the upward motion of a U-shaped area 32c of the lever 32 that is disposed forward of the fulcrum 33. The pin 34 passes through the pair of aligned pin openings 32d, 32e that are provided in opposite sides of the U-shaped area 32c. Between the aligned pin openings 32d, 32e, the pin 34 passes through the pin aperture 24c that is provided in the upper end 24b of the center rod 24. A bottom of the U-shaped area 32c is identified in FIG. 5 by bracket 32m.

[0345] As the lever 32 is further depressed the U-shaped area 32c is progressively raised and the increasing second compressive force prevents downward movement of the lower frame member 18. For certain embodiments of the invention, the second compressive force may flex and urge in an upward direction a modified version of the lower frame member 18. The enlarged head 24a of the center rod 24 applies the upward force to the bottom planar surface 18c of the lower frame segment 18m of the lower frame member 18. An underside of the enlarged head 24a attempts to upwardly compress the plastic of the bottom planar surface 18c of the lower frame member 18 that is disposed above the enlarged head 24a.

[0346] The downward first compressive force applied to the top planar surface 20d of the upper frame member 20 urges the upper frame member 20 in a downward direction, toward the lower frame member 18 as the downward first compressive force is transferred through the plastic below the fulcrum 33 and to the horizontal portion 30 of the upper blade 12. Simultaneously, the upward second compressive force that is applied to the bottom planar surface 18c of the lower frame member 18 prevents downward deflection (i.e., movement) by the lower frame member 18. The upward second compressive force is transferred through the plastic above the enlarged head 24a and to the horizontal portion 30 of the lower blade 14.

[0347] By this arrangement, excessive shear forces are not experienced by the upper frame member 20 or by the lower frame member 18 during a cutting of the nail 8. After transfer of forces by compression through the upper segment 20k and the lower segment 18m to the horizontal portion 30, the horizontal portions 30 of the blades 12, 14 provide stiffening and increased resistance to whatever shear force may be experienced in this area.

[0348] It is important to note that the downward and upward first and second compressive forces experienced by the plastic material of the upper frame member 20 and by the lower frame member 18 occur, respectively, over the horizontal portion 30 of the upper blade 12 and under the horizontal portion 30 of the lower blade 14. These first and second compressive forces are experienced as compressive forces because they occur over the horizontal portion 30 of the upper blade 12 (i.e., through the upper segment 20k of the upper frame member 20) and under the horizontal portion 30 of the lower blade 14 (i.e., through the lower segment 18m of the lower frame member 18). During cutting, force is not applied to any portion of the upper frame member 20 or to any portion of the lower frame member 18 of the nail clipper 10 that does not also include at least a portion of a respective one of the horizontal portions 30, therein.

[0349] If, by way of contrast as compared to the nail clipper 10, such force during cutting is applied to an imagined upper frame member or applied to an imagined lower frame member at a location that does not include a respective one the horizontal portions 30 of the blades 12, 14, therein (Note: this application of force does not occur with the nail clipper 10 as the horizontal portions 30 are present in the nail clipper 10), then the mechanism of transferring these cutting forces through the imagined upper and lower frame members to imagined blades that do not include the horizontal portion 30 would result in a substantial shear force occurring between the imagined upper and lower frame members and the beginning of the imagined blades. The necessary transfer of such a force, during use, from the unreinforced imagined upper and lower frame members (i.e., where the force is applied according to this example, which is included as an illustrative example in contrast to that of the current invention, and wherein the contrasting example includes a teaching that is in opposition to the structure and intent of the nail clipper 10) to each of the imagined blades would, in turn, result in a significant shear force being applied to the unreinforced plastic imagined upper and lower frame members. As a result, the unreinforced plastic imagined upper and lower frame members would likely fracture or bend in response to the excessive shear forces that would be experienced. This problem cannot occur with the disclosed nail clipper 10 because compression, rather than shear, is used to transfer force to the horizontal portion 30 of the blades 12, 14.

[0350] It is by design of the blades 12, 14 to include the horizontal portions 30, embedding the horizontal portions 30 in the front end 20b of the upper frame member 20 and in the front end 18b of the lower frame member 18, including sufficient length in the horizontal portions 30 to ensure that at least a portion of the horizontal portion 30 of the upper blade 12 is disposed under the fulcrum 33 and that at least a portion of the horizontal portion 30 of the lower blade 14 is disposed over the enlarged head 24a of the center rod 24, so that when these elements are included in combination together, the structure of the nail clipper 10 is able to provide the substantial and largely unexpected benefits disclosed herein.

[0351] By relying on the first and second compressive forces that are applied to the upper and lower frame members 20, 18 and by including the horizontal portions 30, the current arrangement avoids areas that could cause the nail clipper 10 to experience an excessive degree of shear force. Instead, the nail clipper 10 uses opposing compressive forces that occur in vertical alignment over a respective portion of each of the horizontal portions 30 of each of the blades 12, 14 to move the horizontal portions 30, which, in turn, then move the upper and lower frame members 20, 18, and the blades 12, 14, and their cutting edges 12a, 14a toward each other during cutting of the nail 8. Therefore, the nail clipper 10 is easily able to withstand the significant compressive forces (and minimal shear forces) that are experienced during use and to transfer the compressive forces to the blades 12, 14 for cutting of the nail 8.

[0352] During actual cutting of the nail 8, the first and second compressive forces are able to urge the opposing pair of cutting edges 12a, 14a of the blades 12, 14 of the nail clipper 10 through the nail 8 without causing damage to the frame 16. The plastic frame 16 experiences little stress during use and is used primarily to maintain the blades 12, 14 in parallel alignment with respect to one-another.

[0353] As mentioned herein, application of the first and second compressive forces applied over the horizontal portion 30 of the blades 12, 14 allows for the nail clipper 10 to be fabricated using a much wider array of polymers and non-metallic materials, thereby further decreasing cost. In particular, less expensive or a greater variety of elastomeric polymers can be used than would otherwise be possible. Not only does this result in a more durable device (i.e., the nail clipper 10) but it also allows the use of polymers and other non-metallic materials that, being more elastic, provide a more aesthetically pleasing feel to the nail clipper 10 during use. Further, less plastic (or other non-metallic material) is required because less strength and rigidity is required of any part of the frame 16 (i.e., any part of the upper and lower frame members 20, 18).

[0354] These and other significant benefits arising from the structure of the nail clipper 10, are described in greater detail, hereinafter, and are not available with prior art nail clippers and, in particular, with an all steel type of prior art device.

[0355] By way of comparison, prior art dual parallel opposing blade types of nail clippers that have frame members (not shown) that are exclusively made of steel and the blades (and their respective cutting edges) are also exclusively made of steel. Furthermore, the prior art steel blades are either integrally formed with the upper or lower frame members of the prior-art nail clippers or the steel blades are attachable to a steel frame in order to provide sufficient strength to withstand the stress caused primarily by shear force that occurs during cutting of a nail with a parallel type of blade cutting action. As a result, such types of prior art nail clippers include a significant amount of steel and require considerable machining which substantially increases their cost and weight. Additionally, a cutting edge of the described prior art upper steel blade must precisely align with a cutting edge of the prior art lower steel blade of the prior art nail clipper which further increases manufacturing cost when compared to the simplicity and low cost of manufacture and of aligning the cutting edges 12a, 14a of the upper and lower blades 12, 14 of the nail clipper 10.

[0356] The nail clipper 10 includes an optional pair of spaced-apart ledges 36a, 36b (FIGS. 6 and 9) disposed on each of the sidewalls 18e, 18f. The ledges 36a, 36b are optionally included to help protect the frame 16 of the nail clipper 10, the blades 12, 14, and the cutting edges 12a, 14a from damage in the event a user (not shown) continues to apply force to the lever 32, in the direction of arrow 50b, after the nail clipper 10 has reached the closed position. In particular, if the user applies excessive force to the lever 32 after the nail clipper 10 has reached the closed position, the ledges 36a, 36b support a bottom surface 20c of the upper frame member 20 at opposite sides of the upper frame member 20. The ledges 36a, 36b can extend as little or as much as desired along any portion of the container sidewalls 18e, 18f. The ledges 36a, 36b preclude further downward movement of the upper frame member 20 after the nail clipper 10 has been urged downward into the fully closed position. Preferably, the ledges 36a, 36b are located under at least a portion of horizontal portion 30, and preferably the ledges 36a, 36b extend the full depth of the horizontal portion 30. In this manner, the ledges 36a, 36b prevent damage from occurring, when excessive force is applied to the lever 32, to any portion of the upper frame member 20 or to the lower frame member 18. The ledges 36a, 36b can easily be included as part of the mold used to form the nail clipper 10 and the ledges 36a, 36b provide a significant structural benefit, when included.

[0357] FIGS. 7 and 10 show the left and right sides of the bottom surface 20c of the upper frame member 20 lightly making contact with (or disposed slightly above) the ledges 36a, 36b when the nail clipper 10 is disposed in the closed position. Additional downward pressure applied to the lever 32 in the direction of arrow 50b will firmly seat the left and right sides of the bottom surface 20c of the upper frame member 20 on the ledges 36a, 36b, thereby preventing additional downward movement by the upper frame member 20 from occurring if an even greater downward force is applied to the lever 32. Preventing additional downward movement will protect the nail clipper 10 from possible damage occurring to the frame 16 or to the cutting edges 12a, 14a.

[0358] Alternately, an upward support protrusion (not shown) that extends upward from a more central area of a top planar surface 18d of the lower frame member 18 could be used to preclude further downward movement by the upper frame member 20. If the upward support protrusion is included it is preferable for the reasons noted above that the upward support protrusion be disposed under as much of the depth of the horizontal portion 30, as possible.

[0359] By this structural arrangement, the upper and lower frame members 20, 18 experience minimal stress and minimal strain even if subjected to limited abuse. Therefore, the upper and lower frame members 20, 18 can be formed primarily (more than 50%) of any desired polymer, (plastic), or other non-metallic material, for example nylon, including using less material and/or a lesser grade (i.e., strength) of material for the frame 16 than would otherwise be possible without the horizontal portions 30 of the blades 12, 14 being embedded in the upper and lower frame members 20, 18.

[0360] The function of the frame 16 with the nail clipper 10 is primarily to maintain parallel alignment of the cutting edges 12a, 14a with respect to one-another. The forces experienced during cutting of prior-art steel-framed dual parallel opposing blade types of nail clippers are applied to the frame and then transferred through the frame of the prior art nail clipper to the blades of the prior art nail clipper predominantly as a shear force that occurs between the body where force is applied and the blades. The steel frame of the prior art nail clipper is able to withstand this level of shear.

[0361] Furthermore, the nail clipper 10 does not require critical mechanical tolerances during manufacture, is undetectable by most airport security screening technologies, and is exceptionally easy and inexpensive to manufacture. It is also considerably lighter in weight than prior art steel blade devices, and it provides other important advantages and benefits not available with the prior art devices, some of which are described, herein.

[0362] Referring now to FIG. 11 is a view in perspective that applies equally to either of the blades 12, 14. FIG. 16 is a bottom view of FIG. 11, taken along the line 16-16 of FIG. 11.

[0363] In order for the nail clipper 10 to operate reliably and withstand the forces experienced during cutting, the blades 12, 14 include a novel structure. The blades 12, 14, as mentioned above, include the horizontal portions 30 which prior art blades of prior art dual parallel opposing blade types of nail clippers do not include. The width and length of the horizontal portions 30 is a design variable. Therefore, any desired change regarding the width or the length or both the width and the length of the horizontal portions 30 is possible. For example if desired, the length of the horizontal portions 30 may be increased (or decreased) while decreasing (or increasing) the width of the horizontal portions 30.

[0364] As shown, the upper and lower cutting edges 12a, 14a are disposed along a straight line. The straight line design for the upper and lower cutting edges 12a, 14a is also reflected in FIGS. 1, 2, 3, 4, 5, 6, 7, 8, 19, 20, and 21. A modification that can be made to the upper and lower cutting edges 12a, 14a for possible use with all possible versions of the nail clipper 10 is discussed in greater detail, hereinafter, and is shown in FIGS. 15 and 17. Other possible blade modifications are also discussed, hereinafter.

[0365] Referring now momentarily to FIG. 14 and, in particular to view 14f1 of FIG. 14, a cross-sectional view of the upper cutting edge 12a is shown. If view 14f1 were turned upside down then it would be representative of the lower cutting edge 14a.

[0366] When the nail clipper 10 is disposed in the open position, the upper and lower cutting edges 12a, 14a (or 52a, 54a, see also FIG. 15) are parallel with respect to each other along both a horizontal axis and a vertical axis. In the open position the upper and lower cutting edges 12a, 14a (or 52a, 54a) are disposed away from each other a sufficient predetermined distance for insertion of the nail 8 (See FIG. 3). When the nail clipper 10 is disposed in the closed position, the upper and lower cutting edges 12a, 14a (or 52a, 54a) remain parallel with respect to each other along both the horizontal axis and the vertical axis. In the closed position, the upper and lower cutting edges 12a, 14a (or 52a, 54a) are disposed closer to each other than they are when the nail clipper 10 is disposed in the open position. It is generally preferred that the cutting edges 12a, 14a (or 52a, 54a) of the nail clipper 10 abut (i.e., touch) each other along most or all of their longitudinal length when the nail clipper 10 is disposed in the closed position. This helps to provide a cleaner cut for the nail 8. However if preferred, the cutting edges 12a, 14a (or 52a, 54a) of the nail clipper 10 may also include a slight overlap (not shown) when the nail clipper 10 is disposed in the closed position.

[0367] Referring momentarily to FIG. 7, where an enlarged front view of the nail clipper 10 is shown disposed in the closed position. The upper and lower cutting edges 12a, 14a abut one another along the entire longitudinal length of the cutting edges 12a, 14a. This is preferred as it provides the cleanest possible cut of the nail 8. However if desired, it is possible to include an offset (not shown) between the cutting edges 12a, 14a and/or to include a slight overlap of the offset between the cutting edges 12a, 14a when the nail clipper 10 is disposed in the closed position. However, the plane of each of the cutting edges 12a, 14a are always parallel with respect to each other.

[0368] FIG. 14 illustrates several other possible cross-sectional views (views 14a1 through 14e1) that illustrate possible variations which can be made to the cutting edges 12a, 14a, as desired. It is, of course possible, to further modify the cross-section of any of the blades 12, 14 as desired to include cross-sections other than as shown, or to combine portions of any of these cross-sectional views (such as a cross-section that includes one-half of view 14a1 and one-half of view 14d1) to create any desired cross-section, in this example, a curved line on one side and a straight line on the remaining side.

[0369] Experimentation with the cross-sectional shape of the cutting edges 12a, 14a is expected to result in further refinement of the shape or contour of the cutting edges 12a, 14a to produce the nail clipping 8a (See FIG. 4) that includes a sharper, cleaner cut (i.e., severed) edge, with a minimally ragged and/or torn appearance or texture. This is because it is desired that the nail 8, after cutting, include as clean and as sharp a cut edge as is possible. This would lessen an amount, and possibly even eliminate, the need for filing. A further objective to decrease the amount of filing required is satisfied by an improvement described hereinafter (see FIG. 11A).

[0370] The more gradual the taper from the cutting edge 12a, 14a to the full thickness 45 of the blade 12, 14 is made, the less is a magnitude of the horizontal force vector that is applied to the nail 8, during cutting of the nail 8 and therefore, also, attempting to urge the nail clipping 8a away from a remainder of the nail 8. As mentioned above, when the cutting edges 12a, 14a are urged deeper into the nail 8 during cutting of the nail 8, the increasing thickness 45 of the blades 12, 14 supplies an increasing magnitude to the horizontal force vector. Therefore, before the nail 8 is finally severed by the cutting edges 12a, 14a, it is actually torn apart from the remainder of the nail 8 and expelled away from the nail 8 at significant velocity.

[0371] It is desirable and another object of the invention to lessen the magnitude of the horizontal force vector to permit a maximum amount of cutting by the cutting edges 12a, 14a to occur while, at the same time, minimizing the tearing that occurs near a center of the nail 8 along the length of cut. Minimizing the horizontal force vector minimizes tearing which, in turn, results in a cleaner edge for the cut nail 8. When a cut nail (not shown) that has not been filed smooth accidentally brushes against the skin of another person, the other person is likely to feel discomfort from the sharp or ragged edge of the torn exterior of the cut nail.

[0372] Optimum design of the cross-sectional shape (i.e., cross-sectional contour) of the cutting edge 12a, 14a can minimize the tearing that occurs. This, in turn, can lessen and may even in certain instances eliminate the need to file the nail 8 after it has been cut using the nail clipper 10.

[0373] For example, an exaggerated-length taper of any of the cross-sectional views of FIG. 14, or of any other conceivable cross-sectional profile, may be preferred for the cutting edges 12a, 14a to minimize tearing of the nail clipping 8a apart from the nail 8 during cutting.

[0374] Referring now momentarily to FIG. 15 and FIG. 17 is shown an enlarged view in perspective of the modified upper blade 52 and the modified lower blade 54, for possible use in the nail clipper 10, as desired. The modified upper blade 52 and the modified lower blade 54 each include the curved modified cutting edge 52a, 54a. The modified upper blade 52 and the modified lower blade 54, like the upper and lower blades 12, 14, are used in pairs (for dual-blade versions of the invention) and either version (straight or curved) can be used with the nail clipper 10 or with any possible embodiment of the invention. It is a matter of design prerogative as to whether the upper and lower blades 12, 14 or the modified upper and lower blades 52, 54 are used or other blade improvements, as described hereinafter.

[0375] The modified cutting edges 52a, 54a are preferred for many versions of the nail clipper 10 because the curvature of the modified cutting edges 52a, 54a approximates a desired finished curvature for the nail 8 after the nail 8 has been cut.

[0376] If desired, the curvature of the modified cutting edges 52a, 54a can be varied to provide a range of finished curvatures for the nail 8, after cutting is completed. The modified cutting edges 52a, 54a provide the desired finished curvature for the nail 8 with a minimum number of cuttings for each nail 8. If the modified cutting edges 52a, 54a are a perfect match for the desired curvature and if a width of the modified cutting edges 52a, 54a equals or exceeds a width of the nail 8 prior to cutting, then it may be possible to obtain the desired curvature of the nail 8, after cutting, with only one cut being required for the nail 8 by the nail clipper 10. See FIGS. 65, 65A, 66, 66A, 66B, and 67 and also FIG. 11A for additional disclosure providing the desired finished curvature.

[0377] The modified cutting edges 52a, 54a, like the upper and lower cutting edges 12a, 14a, can include any desired cross-sectional shape as shown in FIG. 14 or any desired modification, thereto. FIG. 15 and FIG. 17 illustrate the modified blades 52, 54 as including the cross-sectional shape of illustration 14d1 of FIG. 14, although any desired cross-sectional shape is possible.

[0378] The upper blades 12, 52 and the lower blades 14, 54 are formed of a metal, such as steel, or any preferred sufficiently hard and rigid material, such as a ceramic or a sufficiently hard composite material capable of holding an edge for a sufficient period of time to provide a desired service life for the nail clipper 10. Additionally, whatever material is used to form the blades 12, 14, 52, 54 must be capable of providing the necessary mechanical (i.e., structural) support to the upper frame member 20 and to the lower frame member 18 from their respective horizontal portions 30. Whenever discussion herein makes reference to the blades 12, 14, it is understood that the modified blades 52, 54 could be used instead of the blades 12, 14, as desired. Similarly, whenever discussion herein makes reference to the modified blades 52, 54, it is understood that the blades 12, 14 could be used in place of the modified blades 52, 54. Other metals, alloys, composite materials, or non-metallic materials may also be used to form the blades 12, 14, 52, 54, however, the blades 12, 14, 52, 54 are formed of a dissimilar material as compared to a remainder (i.e., the frame 16) of the nail clipper 10.

[0379] It is important to note that the cardinal improvement to the blades 12, 14 and to the modified blades 52, 54 includes the inclusion of the horizontal portion 30 as an integral part of the blades 12, 14, 52, 54. Additionally, the cutting edge 12a, 14a, 52a, 54a is disposed on a first plane and the horizontal portion 30 is disposed on a second plane, where the second plane is disposed at an angle with respect to the first plane. The first plane is identified in FIGS. 11, 11A, and 15 by the vertical plane (bracket 12g, 14g). The second plane extends through a center of the horizontal portion 30. In particular, an angle exists between the first and second planes of the blades 12, 14, 52, 54 which permits as much as possible of the horizontal portions 30 to be embedded in the upper and lower frame members 20, 18 and therefore on the same or similar generally horizontal plane as the front ends 20b, 18b of the upper and lower frame members 20, 18, and wherein the first plane of the cutting edges 12a, 14a, 52a, 54a is more vertically disposed than is the second plane of the horizontal portion 30.

[0380] However as mentioned above, the majority of the frame 16, as compared to either the upper blade 12 or the lower blade 14, is formed of a different (i.e., a dissimilar) material than that used for either of the blades 12, 14 for all versions of the nail clipper 10.

[0381] It is also possible, and for certain versions of the nail clipper 10 may be desirable, to include any desired embedded metallic or non-metallic member to stiffen or reinforce any part of the nail clipper 10. For example, refer to FIGS. 22 and 25 to see various embedded members 32b, 32j (that are each embedded inside of a respective modified type of plastic lever, as shown and described, later).

[0382] The upper blade 12 and the lower blade 14 are preferably identical to minimize parts inventory and thereby help to lower cost of manufacture. If after benefit of these teachings for some reason it was desired to change either the upper blade 12 or the lower blade 14 so that they were not identical this is also, of course, possible though, as mentioned above, it is generally not preferred.

[0383] As the upper blade 12 and the lower blade 14 are preferably identical, all discussion and usage of the straight upper and lower blades 12, 14 apply equally to the modified blades 52, 54. In other words, for all possible embodiments of the current invention it is a design prerogative as to whether the blades 12, 14 are included or whether the modified blades 52, 54 (or any further modification or improvement to any of the blades 12, 14, 52, 54 are utilized).

[0384] It is to be understood that for any embodiment of the nail clipper 10 (or any modification made thereto) which refers specifically to the blades 12, 14 or to the modified blades 52, 54 that either may be used. Therefore, such omission of discussion in the detailed description does not preclude the use of any of the blades 12, 14, 52, 54.

[0385] As shown, the blades 12, 14, 52, 54 each include the center hole 22 through which the center rod 24 (See detail of center rod 24 in FIG. 12) passes. Referring also to FIG. 12, the center rod 24 includes the enlarged head 24a, attached at a bottom, thereof. A cylindrical body extends upward from the enlarged head 24a. The upper end 24b includes the pin aperture 24c, into which the pin 34 is inserted during manufacture along dashed line 34c. Additional assembly of the nail clipper 10 is described in greater detail, hereinafter. Certain alternate embodiments of the invention do not include the center rod 24 and, therefore, the center hole 22 can be eliminated from the blades 12, 14, 52, 54 for these embodiments.

[0386] The blades 12, 14, 52, 54 preferably include one or more means for securing the lower blade 14 (or 54) in position at or proximate the front end 18b (FIG. 1) of the lower frame member 18 and for securing the upper blade 12 (or 52) at or proximate the front end 20b (FIG. 1) of the upper frame member 20. Friction alone or friction in combination with other means or solely other means may also be used.

[0387] As shown in FIGS. 11 and 15, one or more optional securing holes 26 are preferably included, but not mandatory, that pass through each of the horizontal portions 30 of the blades 12, 14, 52, 54. Also shown are a pair of optional side indentations 28 in the horizontal portions 30 that may be included for securing the blades 12, 14, 52, 54 to the respective upper and lower frame members 20, 18. Protrusions (not shown) or indentations (not shown) may similarly be included in the horizontal portions 30 to help secure the blades 12, 14 (52, 54) in position or in the upper and lower frame members 20, 18.

[0388] During manufacture and molding, preferably at least some of the material comprising the upper and lower frame members 20, 18 (i.e., plastic or other non-metallic material) flows through any or all of the securing holes 26 that are included and/or through and around any or all of the side indentations 28 that are included, thereby securing the blades 12, 14, 52, 54 in position with respect to the front ends 18b, 20b of the upper and lower frame members 20, 18.

[0389] The center rod 24 that passes through the center hole 22 of each of the blades 12, 14, 52, 54 also helps to secure the blades 12, 14, 52, 54 in position in the upper and lower frame members 20, 18. If desired, the center hole 22, in combination with the center rod 24, may be used to secure the blades 12, 14, 52, 54 in a desired position in the upper and lower frame members 20, 18 without additional means. The desired position is as shown in all of the drawing FIGURES and occurs when the cutting edges 12a, 14a, 52a, 54a abut each other along their length (i.e., when they are in parallel alignment with respect to each other and the upper and lower cutting edges 12a, 14a, 52a, 54a are in contact with each other) when the nail clipper 10 is disposed in a closed position, as shown in FIGS. 4 and 7 for example.

[0390] An alternate and generally less-desired position occurs when the cutting edges 12a, 14a, 52a, 54a include a slight overlap with respect to each other along their length (i.e., when they are in parallel alignment with respect to each other and when the upper and lower cutting edges 12a, 14a, 52a, 54a include a slight horizontal and/or a slight vertical offset with respect to each other—not shown). The nail clipper 10 (or any embodiment, thereof) would still function, however, it could result in a more ragged (i.e., torn) cut for the finished nail 8, as previously mentioned.

[0391] The upper blade 12 (or 52) is embedded into the front end 20b of the upper frame member 20 and the lower blade 14 (or 54) is similarly embedded into the front end 18b of the lower frame member 18. Where either the blades 12, 14 or the modified blades 52, 54 are described herein it is understood that either may be used, as desired. Preferably during manufacture, the upper and lower frame members 20, 18 are molded over at least a part of the horizontal portion 30 of each of the blades 12, 14, 52, 54. After fabrication by any means, plastic or another non-metallic material adjoins (i.e., covers) the horizontal portions 30 proximate at least a portion of the top blade surface 12f, 14f and/or at least a portion of a bottom blade surface 12b, 14b, and/or at least a portion of either or both of a pair of opposing sidewalls 12c, 12d, 14c, 14d, and/or at least a portion of a rear sidewall 12e, 14e.

[0392] Preferably, the plastic covers and surrounds the horizontal portion 30 over the top blade surface 12f, 14f, and over the bottom blade surface 12b, 14b, and over the pair of opposing sidewalls 12c, 12d, 14c, 14d, and over the rear sidewall 12e, 14e, as shown in FIGS. 2, 3, 4, 6, 7, 9 and 10. This full or complete embedding of the blades 12, 14 (or the modified blades 52, 54) is generally preferred for various reasons. One reason is that none of the horizontal portion 30 is visible with full or complete embedding, and this results in an appearance that is especially aesthetically pleasing. Also, full or complete embedding of the horizontal portion 30 of the blade 12, 14 may result in greater strength for the upper and lower frame members 20, 18 than would occur with a partial embedding. However, any desired degree of latitude in variation in the amount and location of plastic (or other non-metallic material) that extends over any length of the horizontal portion 30 is possible for assembly of the nail clipper 10, as desired as long as the blades 12, 14 (52, 54) are sufficiently secured to the upper and lower frame members 20, 18.

[0393] Refer now momentarily to FIG. 18 where an enlarged cross-sectional view of the first modified dual parallel opposing blade embedded member nail clipper 100, hereinafter referred to as the “first modified nail clipper 100,” is shown. FIG. 18 is taken through the center rod 24, looking toward the rear, similar to view of the nail clipper 10 shown in FIG. 9. The first modified nail clipper 100 is similar to the nail clipper 10, however, the first modified nail clipper 100 includes a modified embedded position for the blades 12, 52, 14, 54. As shown in FIG. 18 the plastic extends over the top blade surface 12f, 14f of the horizontal portion 30 of both of the blades 12, 14, while not entirely extending (i.e., not covering) all of the bottom blade surface 12b, 14b. With this type of partial embedding the bottom blade surface 14b (of the lower blade 14) is either flush with or protruding slightly above the top planar surface 18d of the lower frame member 18. Similarly, the bottom blade surface 12b (of the upper blade 12) is either flush with or protruding slightly below the bottom planar surface 20c of the upper frame member 20.

[0394] To better secure the blades 12, 14 of the first modified nail clipper 100 in position, during fabrication (i.e., molding) plastic is preferably allowed to flow through the securing holes 26. By allowing extra space in a mold (not shown) additional plastic could be included to form an enlarged cap (i.e., a crown) 26a proximate each of the securing holes 26. As shown, the enlarged cap 26a includes a shaped that resembles a cap of a mushroom (not shown) or a rivet head (not shown). As many securing holes 26 as desired can be included in the blades 12, 14.

[0395] If desired, fasteners (such as screws) could be used in lieu of the enlarged caps 26a. If included, the fasteners (i.e., small screws) could pass through the securing holes 26 and into screw openings (not shown) that are provided in the upper and lower frame members 20, 18 under the securing holes 26. Screw threads of the screws would engage with the screw openings to embed, and thereby secure, the blades 12, 14 against the upper and lower frame members 20, 18. Alternately or in conjunction with other means, an adhesive could be used on the top blade surface 12f, 14f and/or on the opposing sidewalls 12d, 14d to secure the blades 12, 14 in position. Either alone or in conjunction with other means, friction between the opposing sidewalls 12d, 14d of the blades 12, 14 and the adjoining portions of the upper and lower frame members 20, 18 may be used as a further alternative means for securing the blades 12, 14 of the first modified nail clipper 100 in position. Also, including a protrusion in the upper and/or lower frame members 20, 18 that engages with the side indentations 28 may be used to increase friction or to better secure the blades 12, 14 in position.

[0396] Numerous alternative positions and means of attachment (i.e., means for securing) of the blades 12, 14 consistent with the cardinal teaching herein, are possible for the first modified nail clipper 100. Additionally, any means for securing the blades 12, 14 to the upper and lower frame members 20, 18 disclosed herein or which would be obvious to those having ordinary skill in the art after benefit of this disclosure that is consistent with the teachings herein is available for use with the nail clipper 10 or the first modified nail clipper 100 as desired, or with any possible alternative embodiment of the invention.

[0397] The cardinal teaching for all embodiments of the nail clipper 10 or the first modified nail clipper 100 or any other possible variation/embodiment thereof, whether specifically disclosed herein or not, requires that the horizontal portion 30 of the upper blade 12, (and preferably for the lower blade 14) extend sufficiently far into the upper and lower frame members 20, 18 so that a portion of the horizontal portion 30 of at least one of the blades 12 (the upper blade 12) is disposed in the upper frame member 20 and is in vertical alignment with the downward first compressive force applied by the fulcrum 33 of the lever 32, and preferably so that a portion of the horizontal portion 30 of a remaining one of the blades 14 (the lower blade 14) is disposed in the lower frame member 18 and is in vertical alignment with the upward second compressive force applied by the enlarged head 24a of the center rod 24.

[0398] If this cardinal teaching is satisfied (i.e., the horizontal portion 30 of at least the upper blade 12 (or 52) extends beyond the location of a downward force that is applied to the upper frame member 20), an amount of shear stress that is experienced by the upper frame member 20 (and if constructed as shown for any of the embodiments, also for the lower frame member 18) during cutting of the nail 8 is sufficiently decreased to then permit fabrication of the upper and lower frame members 20, 18 primarily (over 50%) from plastic or from another preferred non-metallic material. This, in turn, provides numerous benefits and advantages, many of which are unexpected, and it provides an ability to expand both utility and aesthetics of the nail clipper 10 or the first modified nail clipper 100 in ways not previously available. Fabrication of the nail clipper 10 or the first modified nail clipper 100 (or any other embodiment, thereof) in a manner consistent with this cardinal teaching overcomes a long-standing need that has not been adequately satisfied before the current invention.

[0399] It is important to note that a further modification to the nail clipper 10 (or to any modified dual parallel opposing blade embodiment, thereof) is possible that would allow for shortening or possibly for the elimination of one of the horizontal portions 30, specifically for the lower blade 14 or for the lower modified blade 54. This is because the (vertical) container sidewalls 18e, 18f that are attached to the lower frame member 18 provide significant stiffening for the lower frame member 18. The stiffening provided by the container sidewalls 18e, 18f resists flexing by the lower frame member 18 during use. Accordingly, during use it is primarily the upper frame member 20 of the nail clipper 10 that flexes.

[0400] The stiffening provided to the lower frame member 18 by the container sidewalls 18e, 18f also significantly increases the lower frame member's 18 ability to resist the application of shear force to the lower frame member 18. Therefore, inclusion of the embedded horizontal portion 30 of the lower blade 14 (or 54) past the center rod 24 can be eliminated, if desired. In other words, it is possible to include a modified horizontal portion (not shown) that is shorter in length than the horizontal portion 30 for the lower blade 14 (or for the lower modified blade 54) and for the modified lower frame member (not shown) that includes the container sidewalls 18e, 18f and the shorter horizontal portion 30 to provide sufficient strength and structural integrity to function properly. The stiffening provided by the container sidewalls 18e, 18f can, instead, be used to stiffen and provide increased resistance to shear for the modified lower frame member.

[0401] It is also possible to include the (shortened horizontal portion 30 length) modified blade and provide sufficient stiffening to the lower frame member 18 by means other than the use of the container sidewalls 18e, 18f or in addition to the use of the container sidewalls 18e, 18f. For example, the lower frame member 18 could be modified so that it was considerably thicker, or to include a different or a modified embedded member other than the horizontal portion 30 that is embedded therein, or by the use of a stiffer material added to or blended in with the non-metallic material. In particular, refer momentarily to FIGS. 58A, 58B, 59, 59A, 59B, and 61 that illustrate various alternative embedded discreet members and other possible modifications to the horizontal portion 30 of the blades 12, 14, 52, 54. These and other means may be used to form the resulting modified lower frame member that eliminates the need for a longer horizontal portion 30 of the lower blade 14 (or 54).

[0402] It is also possible to invert the nail clipper 10 along with the preceding teachings. See FIGS. 30 and 31 and an accompanying description, hereinafter. In this example, an inverted lower frame member 818 must be able to flex between the open and closed positions. Therefore, the inverted lower frame member 818 must include the lower blade 14 (or the modified lower blade 54) that also must include the horizontal portion 30 that extends beyond a vertical line where a force that causes the inverted lower frame member 818 to flex is applied. Although it is preferred that an inverted upper frame member 820 include the upper blade 12 (or the modified upper blade 52) that also includes the horizontal portion 30 it is possible to use a shorter horizontal portion 30 and rely on a pair of inverted sidewalls 820e and 820f to provide increased strength and resistance to shear for the inverted upper frame member 820.

[0403] What is essential for operation of the nail clipper 10 (or any embodiment of the invention) is that either the upper frame member 20 or the lower frame member 18 is able to flex enough for the nail clipper 10 to be repeatedly urged from the open position to the closed position and back again. It is also possible that both may flex equally. See FIGS. 32, 32A and 32B. When only one of the frame members (20 for the nail clipper 10, 820 for the eighth modified nail clipper 800) experiences the bulk of the flexing that occurs, then that frame member (20, 820) must include the horizontal portion 30. Although preferred, the horizontal portion 30 may be eliminated from inclusion in the opposite frame member (18, 818) and the shorter horizontal portion may instead be utilized if the opposite frame member (18, 818) is sufficiently stiff.

[0404] The use of friction as an alternative means for securing the blades 12, 14 in the upper and lower frame members 20, 18 is additionally described, hereinafter, along with a description of the embodiment of FIG. 33.

[0405] Continuing to refer on occasion to FIGS. 1, 6 and 9 and especially to FIG. 3, each of which is illustrative of the nail clipper 10 disposed in the open position. Hysteresis of the plastic or other material used to fabricate the frame 16 and disposed at the distal end 18a of the lower frame member 18 and at the distal end 20a of the upper frame member 20 (i.e., at the vertical rear wall 19) supplies a force that is normally urging the upper frame member 20 upward and away from the lower frame member 18. If desired, a wedge (not shown) and/or a spring (not shown) may be included between the upper and lower frame members 20, 18 to supply an even greater separating force. Refer also to co-pending patent application Ser. No. 13/385,701, which is included herein by way of reference, for additional information regarding the use of the spring and/or wedge. Different polymers exhibit different properties, including different elastomeric characteristics and/or different amounts of hysteresis. The polymer (plastic) or other non-metallic material that is chosen for the frame 16 is selected, as desired, to include whatever properties are deemed to be most important. It is also possible to include a plurality of non-metallic materials to fabricate the frame 16 or other component parts of the nail clipper 10, or other embodiment. For example, the frame 16 could be fabricated (molded) from any desired polymer or plurality of polymers that also includes a fiberglass or other webbing or filament embedded where desired, for added stiffening and increased hysteresis. See FIGS. 62 and 63 for additional disclosure regarding the use of reinforcing strands. Alternately, the upper frame member 20 could be formed from a first type of polymer, the lower frame member could be formed from a second type of polymer, and the rear wall 19 could be formed from a third type of polymer or other variation. If desired, a non-metallic material other than a polymer could be used in lieu of the first, second or third type of polymer to form the greater portion (i.e., more than 50%) of these component parts of the nail clipper 10.

[0406] The maximum amount of separation between the upper and lower frame members 20, 18, as mentioned above, is limited after assembly by the length of the center rod 24, and by its positional attachment to the lever 32.

[0407] Prior to a completion of manufacture, before inclusion of the center rod 24, the upper frame member 20 must be minimally capable of being urged upward (away from the lower frame member 18) into the fully open position, as shown in FIGS. 1, 3, 6, and 9. The magnitude of available hysteresis can also be increased by including an even greater separation than is required when the nail clipper 10 is disposed in the open position between the front end 20b of the upper frame member 20 and the front end 18b of the lower frame member 18 during molding of the frame 16. Inclusion of a greater separation during formation of the frame 16 increases the inherent magnitude of hysteresis that urges the upper and lower frame members 20, 18 apart. After assembly, when the nail clipper 10 is disposed in the open position, the upper frame member 20 is preferably disposed closer to the lower frame member 18 than they are disposed prior to assembly of the nail clipper 10 (in particular, prior to inclusion of the center rod 24 and attachment of the lever 32, thereto). In other words, after formation of the upper frame member 20 and the lower frame member 18 hysteresis is tending to urge the upper frame member 20 and the lower frame member 18 further apart than they are disposed after attachment of the lever 32 to the center rod 24 has occurred (i.e., than when the nail clipper 10 is disposed in the open position). Therefore, when the nail clipper 10 is disposed in the open position, hysteresis is attempting to urge the upper frame member 20 and the lower frame member 18 further away from each other, but this is prevented by cooperation of the center rod 24 and the lever 32 acting on the lower frame member 18 and the upper frame member 20. This added separation force ensures that sufficient tension is present at a bottom of the U-shaped recessed area 32c of the lever 32 to maintain the lever 32 as shown when the nail clipper 10 is disposed in the open position.

[0408] The plastic (or other non-metallic) material used to form the upper and lower frame members 20, 18 is, to a certain degree, innately flexible. The flexibility of the upper and/or lower frame members 20, 18 correspond with an inherent elasticity of the material(s) used to form the upper and lower frame members 20, 18 and, additionally, to the manner in which the upper and lower frame members 20, 18 are attached to a remainder of the nail clipper 10. Innovative options for varying flexibility of the upper frame member 20 and/or the lower frame member 18 by various means are disclosed, herein. Hysteresis, as used herein, refers to an inherent tendency of the material that is used to form the upper and lower frame members 20, 18, to return to the respective original positions that they first had after molding (i.e., after the frame 16 has initially been formed and/or assembled). Therefore, as used herein, the term “hysteresis” refers to the inherent flexibility or elasticity of the plastic or other non-metallic material used to form the upper frame member 20 and/or the lower frame member 18 as supplying a force that is always attempting to urge the upper and lower frame members 20, 18 apart from each other and into their original positions.

[0409] Additionally, it may be desirable to form portions of the frame 16 of the nail clipper 10 out of two or more different non-metallic materials that are layered. For example, the inclusion of an overlay 80 (shown in dashed lines in FIG. 19) of a more elastomeric non-metallic material can be applied over, under, or in-between any desired portion of the nail clipper 10. The overlay 80 may be applied to an exterior of the frame 16 and used to provide a softer, more compliant feel to the nail clipper 10 or an enhanced appearance. The size of the optional overlay 80, as shown in FIG. 19, can be increased or decreased, as desired. The overlay 80 may be strategically applied, where desired, to the nail clipper 10. Alternately, the overlay 80 may include an interior overlay portion 80a as shown in angled lines that is disposed between the upper and lower frame members 20, 18 proximate their distal ends 20a, 18a to provide additional force for urging the upper and lower frame members 20, 18 apart and the nail clipper 10 into the open position. The interior overlay portion 80a acts as a wedge (as previously described) to help urge the upper and lower frame members 20, 18 apart. The interior overlay portion 80a may be connected to the exterior overlay 80 or not, as desired.

[0410] Therefore, either sufficient hysteresis and/or additional means, such as the overlay portion 80, the interior overlay portion 80a, the spring and/or the wedge or other means are included, as desired, to supply whatever force is necessary to urge the upper frame member 20 apart from the lower frame member 18 an amount sufficient to place the nail clipper 10 in the open position, when desired. Alternately as desired, the amount of plastic (or other material) included at or proximate the vertical rear wall 19 during molding can also be increased to provide an increased amount of hysteresis (force) as desired to urge the upper frame member 20 upward and away from the lower frame member 18 a sufficient amount.

[0411] It is also possible to increase the amount of attachment of the upper frame member 20 proximate the vertical rear wall 19 if increased stiffness and increased hysteresis for the upper frame member 20 is desired. Referring to FIG. 1 a pair of gaps, identified in general by the reference numeral 81, exists between each of the vertical planar surfaces 20g, 20h of the upper frame member 20 and the vertical interior surfaces of the first and second container sidewalls 18f, 18e, respectively. A first distal end 81a of each of the two gaps 81 is preferably disposed the same distance from the plane of the rear wall 19 to prevent possible rotation of the upper frame member 20 with respect to the lower frame member 18 as the upper frame member 20 is urged toward the lower frame member 18 (i.e., when the nail clipper 10 is urged into the closed position).

[0412] A possible alternate location for a modified pair of second distal ends of the gaps 81 is shown by dashed line 81b. If the longitudinal length of the gaps 81 were shortened to instead end at the second distal end (i.e., at dashed line 81b) instead of at the first distal end 81a, a greater amount of the upper frame member 20 would be attached to the first and second container sidewalls 18e, 18f (during molding of the frame 16) and therefore the upper frame member 20 would include a shorter longitudinal length (along the gaps 81) that was available for flexing. The upper frame member 20 is intended to flex primarily along the length of the gaps 81. However, the upper frame member 20 strongly resists any flexing along the length of the horizontal portion 30 which stiffens the upper frame member 20. Therefore, the bulk of flexing occurs between a rear of the horizontal portion 30 and the first distal end 81a (or at dashed line 81b if the gap 81 length is shortened). All other variables not changing, the possible location for the pair of second distal ends (i.e., along dashed line 81b) can be used to increase stiffness and hysteresis of the upper frame member 20 as compared to if the two gaps 81 were extended and disposed at the first distal ends 81a. Accordingly, shortening the length of the gaps 81 can be used to increase hysteresis force as well as stiffness and thereby to decrease flexibility while a lengthening of the gaps 81 can be used to decrease hysteresis force as well as stiffness and increase flexibility of the upper frame member 20.

[0413] If, prior to completion of manufacture (i.e., prior to inclusion of the center rod 24 and the lever 32) a sufficient force urging the upper frame member 20 in an upward direction away from the lower frame member 18 is available (by hysteresis, the spring, or the wedge or by any preferred means or combination, thereof), the upper frame member 20 may rise above the fully open position. That is, in fact, likely to occur. It may, therefore, be necessary during assembly (i.e., manufacture) of the nail clipper 10 to first slightly urge the upper frame member 20 downward, toward the lower frame member 18, in order to then properly insert the center rod 24 and attach the lever 32 to the center rod 24 by inserting the pin 34 through the pair of aligned pin openings 32d, 32e. However, after inclusion of the center rod 24 and attachment of the lever 32 to the center rod 24 has occurred during manufacture of the nail clipper 10, the maximum upward movement of the upper frame member 20 will be limited to that as defined by the fully open position.

[0414] FIG. 3 shows the nail 8 disposed slightly away from the blades 12, 14. Prior to cutting of the nail 8, the user will urge the nail 8 in the direction of arrow 37 until either the nail 8 has been urged a desired distance in the direction of arrow 37 or until a fleshy portion 9a of a finger 9 of the user contacts an optional safety bumper, identified in general by the reference numeral 39. The safety bumper 39 extends below and forward of the cutting edge 14a of the lower blade 14, and is used to limit the depth of cut of the nail 8 that is possible. Different contours and projections of the safety bumper 39 are, of course, possible to provide a different overall length of the nail 8 after it has been cut. Refer again to co-pending patent application Ser. No. 13/385,701 for additional information regarding the safety bumper 39.

[0415] The first and second container sidewalls 18e, 18f each optionally include, at a forward end, thereof, between the front end 18b of the lower frame member 18 and the front end 20b of the upper frame member 20, a first nail recess 41a disposed in the first container sidewall 18e and a corresponding second nail recess 41b (See FIGS. 3 and 7) disposed in the second container sidewall 18f. The first and second nail recesses 41a, 41b, being part of the first and second container sidewalls 18e, 18f, are disposed in a spaced-apart orientation with respect to each other. The first and second nail recesses 41a, 41b allow the nail 8 to be inserted a greater distance in the direction of arrow 37, as desired, providing that sufficient contact of the fleshy portion 9a of the finger 9 with the safety bumper 39 does not occur before the nail 8 has been maximally inserted between the cutting edges 12a, 14a.

[0416] The first and second nail recesses 41a, 41b thereby permit more of the nail 8 to be removed during each cutting (i.e., a larger nail clipping 8a), thereby possibly lessening a time required to cut the nail 8.

[0417] FIG. 6 is front view of the nail clipper 10 of FIG. 3 disposed in the open position and FIG. 6 shows additional detail of its construction. Select aspects of the nail clipper 10 are shown in dashed lines throughout this disclosure to better reveal its construction. For example in FIG. 6, the top blade surface 12f of the horizontal portion 30 of the upper blade 12 is shown in a solid line and the bottom blade surface 12b of the upper blade 12 is shown in a dashed line. Similarly, the top blade surface 14f of the bottom blade 14 is shown in a solid line and the bottom blade surface 14b of the bottom blade 14 is shown in a dashed line. The top blade surfaces 12f, 14f and the bottom blade surfaces 12b 14b extend along the entire width and length of the horizontal portions 30 of the blades 12, 14.

[0418] The bottom surface 20c of the upper frame member 20 is shown in a dashed line (under the vertical portion or vertical plane 12g of the upper blade 12) and in solid lines on opposite sides of the blade 12. The top planar surface 18d of the lower frame member 18 is shown in a dashed line (under the vertical portion or vertical plane 14g of the lower blade 14). The bottom planar surface 18c of the lower frame member 18 is shown in a solid line. The area provided by the first and second nail recesses 41a, 41b is shown in solid lines.

[0419] During manufacture of the blades 12, 14, a bend of approximately ninety degrees, plus or minus any desired amount, is provided between the (first) vertical plane 12g, 14g that the cutting edges 12a, 14a are disposed on and the second horizontal plane of the horizontal portions 30. Inclusion of the horizontal portion 30 and a change in angle between the vertical plane 12g, 14g of the cutting edges 12a, 14a and the second horizontal plane of the inventive horizontal portion 30 is an improvement in design over prior art nail clipper opposing parallel blade design.

[0420] Additionally, a portion of the pin 34 that is not visible in FIG. 3 is also shown in dashed lines in FIG. 6. Also, portions of the center rod 24 not visible in certain of the FIGURE drawings are shown in dashed lines in FIG. 6.

[0421] The optional pair of ledges 36a, 36b, are included as molded inward extensions of the first and second container sidewalls 18e, 18f and are visible below the bottom surface 20c of the upper frame member 20. Therefore, the ledges 36a, 36b are disposed away from and, accordingly, do not contact the bottom surface 20c of the upper frame member 20 when the nail clipper 10 is disposed in the open position.

[0422] FIG. 9 is a cross-sectional view of the nail clipper 10 in the open position taken vertically through the center rod 24. The horizontal portions 30 of the upper and lower blades 12, 14 are shown embedded in the upper and lower frame members 20, 18, respectively and extending further into the body of the upper and lower frame members 20, 18. See also FIGS. 3, 4, and 5. Therefore, a portion of the horizontal portion 30 of the lower blade 14 is disposed in vertical longitudinal alignment with respect to the center rod 24. This, in turn, ensures that a lesser magnitude of shear force is experienced by the lower frame member 18 than would occur if the horizontal portion 30 did not extend beyond the position of the center rod 24. FIGS. 3, 4, and 5 show that the horizontal portions 30 of the upper blade 12 of the nail clipper 10 extend beyond (i.e., further to the rear) of a vertical dashed fulcrum line 33b (FIG. 4) that passes through the fulcrum 33 of the lever 32. This, in turn, ensures that a lesser magnitude of shear force is experienced by the upper frame member 20 than would occur if the horizontal portion 30 did not extend beyond the position of the fulcrum 33. See also FIGS. 19, 20 and 21 for alternate embodiments of the invention that also include horizontal portions 30 that extend rearward of each of the center rods 24 and rearward of each of the fulcrums 33.

[0423] Also, clearly shown in FIG. 9 are the optional pair of ledges 36a, 36b that are included, respectively in the first container sidewall 18e and the second container sidewall 18f. As shown, the ledges 36a, 36b include a contour that corresponds with a bottom contour of the upper frame member 20 disposed above each of the ledges 36a, 36b. If included, the ledges 36a, 36b are preferably disposed between the horizontal portions 30 of the blades 12, 14 where maximum strength of the upper and lower frame members 20, 18 occurs. The ledges 36a, 36b help to prevent unwanted tilting or bending of the upper and lower frame members 20, 18 at this important area when excessive force is applied to the lever 32 after the nail clipper 10 has reached the closed position.

[0424] Referring again also to FIG. 3, the ledge 36a that is included in the first container sidewall 18e is shown as a dashed line. It is important to note that the ledges 36a, 36b can easily be included in the nail clipper 10 by molding the ledges 36a, 36b as integral component parts of the sidewalls 18e, 18f of the lower frame member 18. This is true whether the frame 16 is of a one-piece design, as shown for the nail clipper 10, or if it is a two-piece design. Inclusion of the ledges 36a, 36b or providing any other supplemental means (in addition to contact of prior art cutting edges with one-another) that limit approach of the upper and lower frame members 20, 18 toward each other or which prevent damage from excessive pressure being applied, are not previously known for dual parallel opposing blade types of nail clippers.

[0425] It is also important to note that the inclusion of the sidewalls 18e, 18f, whether as separate component parts or as integral component parts of the lower frame member 18, is also not previously known for this type of device. However, it is a relatively simple matter to include the sidewalls 18e, 18f in the basic mold that provides the lower frame member 18, whether the frame 16 is of one-piece construction, as is the case with the nail clipper 10 or if the frame 16 is of a two-piece construction (See FIGS. 27 and 28 for an example of two-piece construction).

[0426] Inclusion of the sidewalls 18e, 18f and disposing the upper frame member 20 between the sidewalls 18e, 18f promotes proper operation of the upper frame member 20 to be urged downward during cutting, toward the lower frame member 18 until the nail clipper 10 is disposed in the closed position, and then upward again to the open position by permitting vertical movement of the upper frame member 20 to occur between the two opposing sidewalls 18e, 18f.

[0427] This structure also provides a container area disposed in an interior of the nail clipper 10 when the nail clipper 10 is disposed in the open and in the closed position (and anywhere in-between). When the nail clipper 10 is disposed in the closed position the cutting edges 12a, 14a abut each other and thereby provide a closure at the front end of the container area. The interior surfaces of the opposing sidewalls 18e, 18f provide closure along the sides of the container area. The bottom surface 20c of the upper frame member 20 provides closure along the top of the container area. The top planar surface 18d of the lower frame member 18 provides closure along the bottom of the container area. The rear vertical wall 19, if included, provides closure of the container area at the rear of the nail clipper 10. If the rear wall 19 is omitted on a modified version of the invention, the area where the upper frame member 20 is attached to the lower frame member 18 at the distal ends 20a, 18a, respectively, provides alternate means for closure of the container area at the rear. Accordingly, the container area of the nail clipper 10 is able to capture the nail clipping 8a, therein.

[0428] Additionally, at the moment the nail clipping 8a is severed apart from the nail 8, the nail clipping 8a is ejected into the container area where it is captured. After continued use numerous nail clippings 8a will accumulate in the interior (i.e., container area) of the nail clipper 10. To remove the nail clippings 8a from the container area, the nail clipper 10 is disposed in the open position and held over a waste-basket (not shown) with the blades 12, 14 facing downward. The nail clipper 10 is then shaken up and down until all or a sufficient number of the nail clippings 8a have fallen out of the nail clipper 10 from between the cutting edges 12a, 14a and into the waste-basket.

[0429] In order for the container area (that is created by the container sidewalls 18e, 18f, the upper frame member 20, the lower frame member 18, the vertical rear wall 19, and at the front blades 12, 14) to effectively capture the nail clipping 8a, the container sidewalls 18e, 18f must extend upward from the lower frame member 18 toward the upper frame member 20 an amount sufficient for the upper edges 18e1, 18f1 of the container sidewalls 18e, 18f to at least reach, and preferably overlap, the bottom surface 20c (or sides) of the upper frame member 20 when the nail clipper 10 is disposed in the closed position. This helps to ensure that the nail clipping 8a, at the moment of its being severed from a remaining portion of the nail 8, will be captured in the container area. To better retain the nail clipping 8a in the container area it is preferable to extend the container sidewalls 18e, 18f higher so that the upper edges 18e1, 18f1 of the container sidewalls 18e, 18f at least reach the bottom surface 20c of the upper frame member 20 when the nail clipper 10 is disposed in the open position. This helps retain the nail clipping 8a in the container area until deliberate discharge of the nail clipping 8a from the container area is desired.

[0430] However, other important benefits are provided by extending the container sidewalls 18e, 18f further upward so that at least a portion of the upper edges 18e1, 18f1 correspond in elevation with the top planar surface 20d of the upper frame member 20. This helps prevent undesired movement by the lever 32 during cutting of the nail 8. Further benefits are obtained by further elevating the upper edges 18e1, 18f1 of the container sidewalls 18e, 18f above the top planar surface 20d as shown in FIGS. 62 and 63 and later described.

[0431] To understand the purpose of the ledges 36a, 36b, additionally refer to FIGS. 4, 7, and 10 which show the nail clipper 10 disposed in the closed position. The nail 8 is not shown in FIG. 4, however the nail clipping 8a is shown disposed in the container area (i.e., in an interior portion) of the nail clipper 10. This is consistent with normal usage because after insertion of the nail 8, as previously described, between the cutting edges 12a, 14a and after having fully depressed the lever 32 in the direction of arrow 50b (FIG. 4), the nail clipper 10 will be disposed in the closed position and the nail clipping 8a will be captured in the container area (interior) of the nail clipper 10. Capture of the nail clipping 8a is generally preferred because it provides an environment that is free of a scattering of the nail clippings 8a. After the nail clipping 8a has been produced, it is assumed that cutting of the nail 8 is now complete. The finger 9 and nail 8 will then be pulled back and away from the nail clipper 10. If additional nails 8 (not shown) are to be cut or if the nail 8 is to be further cut, the previously described and illustrated process is repeated as often as needed.

[0432] When the nail clipper 10 is disposed in the closed position, the bottom surface 20c of the upper frame member 20 is disposed even with or it is disposed slightly above the top of the ledges 36a, 36b. Referring momentarily now to FIGS. 3 and 4, the ledge 36b is disposed within the container area (interior) of the nail clipper 10 and is, therefore, hidden from view. The opposite ledge 36a that is included as an integral part of the first container sidewall 18e is shown by use of dashed lines.

[0433] If desired, the ledges 36a, 36b can include a slight rise as they progress toward the rear of the first and second container sidewalls 18e, 18f, as shown in FIGS. 3 and 4 (and other FIGURES), to better correspond with an angle of the bottom surface 20c of the upper frame member 20 when the nail clipper 10 is disposed in the closed position. The slight rise of the ledges 36a, 36b ensures that most, if not all of the bottom surface 20c of the portion of the upper frame member 20 that is disposed above the ledges 36a, 36b is in parallel alignment with the ledges 36a, 36b when the nail clipper 10 is disposed in the closed position.

[0434] If the user continues to apply force to the lever 32 in the direction of arrow 50b after the nail 8 has been cut, additional friction between the cutting edges 12a, 14a can occur, which is generally undesirable, as it may lead to premature dulling of the cutting edges 12a, 14a or even cause damage to the cutting edges 12a, 14a or possibly elsewhere. Additionally, there is also increasing risk that continuation of an application of excessive force to the lever 32 in the direction of arrow 50b after the nail clipper 10 is disposed in the closed position can cause damage to the enlarged head 24a, elsewhere to the center rod 24, to the front end 18b of the lower frame member 18 or to the front end 20b of the upper frame member 20 or elsewhere along the length of the upper and lower frame members 20, 18.

[0435] However, contact by the bottom surface 20c of the upper frame member 20 with the ledges 36a, 36b limits movement of the upper frame member 20 and the lower frame member 18 toward each other. This significantly lessens the likelihood of damage occurring to any of the component parts of the nail clipper 10, thereby extending the useful life of the nail clipper 10.

[0436] In particular, other benefits also arise. For example, the ledges 36a, 36b allow the frame 16 of the nail clipper 10 to be formed primarily of plastic or of another non-metallic material and be even more resistant to damage from abuse than would otherwise be possible.

[0437] The ledges 36a, 36b provide further unexpected benefits and advantages. Additionally, the ledges 36a, 36b provide a firm and positive stop that limits downward motion of the upper frame member 20 with respect to the lower frame member 18. This creates a firm “stop” that provides tactile feedback to the user. The tactile feedback, over the course of time, helps to “condition” the user to stop applying force to the lever 32 once the final click indicating that the nail clipping 8a has been severed is heard and from the tactile feedback that occurs when the closed position is reached and the ledges 36a, 36b provide a firm and positive cessation of movement by the upper frame member 20 and, therefore, by the lever 32 as well.

[0438] The firm stop provided by the ledges 36a, 36b also includes a small amount of elasticity due to the slightly elastic (i.e., elastomeric) nature of plastic. This, in turn, provides an aesthetically pleasing feel for the nail clipper 10 during use that, it is believed, many users will find far more satisfying than the cold hard feel that accompanies use of a prior art steel-frame dual parallel opposing blade type of nail clipper. Prior art dual parallel opposing blade types of nail clippers fail completely to address these issues and long-standing needs and, accordingly, provide no solution to these needs.

[0439] Alternately, a lower support protrusion (not shown) that extends upward from a central area of a top of a modified lower frame member could be included (i.e., molded) as part of the modified lower frame member and similarly used to preclude further movement of the upper frame member 20 and the modified lower frame member toward each other, either with or without inclusion of the ledges 36a, 36b. Alternately, the lower support protrusion could be omitted and an upper support protrusion that extends downward from a central area of a bottom of a modified upper frame member could, instead, be included (i.e., molded) as part of the modified upper frame member. Or, if desired, a modified lower support protrusion that is not as high as the lower support protrusion could be included (i.e., molded) as part of the modified lower frame member along with inclusion of a modified upper support protrusion that is not as high as the upper support protrusion could, instead, be included wherein the combined height of the modified upper support protrusion plus the height of the modified lower support protrusion is equal to the height of either the upper support protrusion or the height of the lower upper protrusion. If any support protrusion(s) is/are included it is preferable for the reasons noted above that they are disposed in vertical alignment with as much of the horizontal portion 30, as possible for the same reasons as appertaining to the preferred location for the ledges 36a, 36b. However, the support protrusions, if included, can provide an obstacle that could hinder capture of the nail clipping 8a. Therefore, the ledges 36a, 36b are preferred.

[0440] By this structural arrangement, the upper and lower frame members 20, 18 experience minimal shear and, accordingly, minimal structural stress. Therefore, the upper and lower frame members 20, 18 can be formed primarily (more than 50%) of any desired polymer, (plastic), or other non-metallic material, for example nylon, including using less material and/or a lesser grade (i.e., strength) of material for the frame 16 than would otherwise be possible without at least one of the horizontal portions 30 of the blades 12, 14 being embedded in at least one of the upper or lower members 20, 18.

[0441] When the nail clipper 10 is disposed in the open position (as shown in FIGS. 1, 3, 6, and 9) the top planar surface 20d of the upper frame member 20 is disposed at approximately the same height as an upper edge 18e1, 18f1 (See FIGS. 6-9) of the first and second container sidewalls 18e, 18f, respectively. Therefore, the bottom 32m of the U-shaped area 32c is disposed at, or slightly above, the height of the upper edges 18e1, 18f1. This allows rotation of the lever 32 to occur around the center longitudinal axis 13 of the center rod 24. See arrow 50 of FIG. 1 and also refer to a discussion regarding a rest position for the nail clipper 10 that follows regarding rotation of the lever 32 around the center longitudinal axis 13.

[0442] When the nail clipper 10 is initially disposed in the open position and an end 32n of the lever 32 is depressed downward (toward the frame 16) in the direction of arrow 50b (FIG. 4), the top planar surface 20d of the upper frame member 20 is progressively urged by the fulcrum 33 below the upper edges 18e1, 18f1 of the first and second container sidewalls 18e, 18f, respectively, until the lever 32 has been maximally urged downward and the nail clipper 10 is disposed in the closed position. When the lever 32 is urged downward, force can be applied anywhere along the upper portion 32a of the lever 32, however, a greater mechanical advantage is attained when applying force as close to the end 32n of the lever 32, as practical. In the closed position, the fulcrum 33 is disposed between the container sidewalls 18e, 18f at its lowest position during normal usage. FIGS. 7 and 10 show the fulcrum 33 disposed between the first and second container sidewalls 18e, 18f and well-below the upper edges 18e1, 18f1. The preceding discussion explains the elevated position of the fulcrum 33 at or slightly above the upper edges 18e1, 18f1 when the nail clipper 10 is disposed in the open position and the maximally lowered position of the fulcrum 33 when the nail clipper 10 is disposed in the closed position.

[0443] It is important to note that when the nail clipper 10 is disposed in the open position, as soon as the user begins to depress the lever 32 downward in the direction of arrow 50b, the fulcrum 33 is immediately urged slightly below the upper edges 18e1, 18f1. The fulcrum 33 remains below the upper edges 18e1, 18f1 during cutting of the nail 8 (i.e., during the entire transition of the nail clipper 10 from the open position to the closed position).

[0444] This provides an important and unexpected benefit, not previously available with any prior art dual parallel opposing blade type of nail clipper. A prior art lever (not shown) of prior art dual parallel opposing blade types of nail clippers is able to rotate around a center longitudinal axis of the prior art center rod (not shown) during actual use (i.e., during cutting). It is important to note that, when cutting, considerable force must be applied to the prior art lever. Because of the possibility of rotation, the prior art lever can inadvertently rotate around the center longitudinal axis of the prior art center rod. This is proportionately more likely to occur as increasingly greater force is applied to the prior art lever by the user. This can cause the prior art nail clipper to inadvertently become dislodged, possibly resulting in the prior art cutting edges striking the user and possibly cutting or causing other injury to the user.

[0445] By way of contrast the nail clipper 10 prevents this type of rotation from occurring during use. As soon as the lever 32 of the nail clipper 10 is even slightly depressed, at the beginning of the transition from the open position to the closed position, the fulcrum 33 is immediately urged below the upper edges 18e1, 18f1 and, thereby, between the opposing first and second container sidewalls 18e, 18f. This occurs because it is preferable that the design of the nail clipper 10 dispose the plane of the top planar surface 20d of the upper frame member 20 proximate the center rod 24 at or near the top of the upper edges 18e1, 18e2 of the opposing container sidewalls 18e, 18f. Therefore, any depression of the lever 32 when the nail clipper 10 is disposed in the open position lowers the fulcrum 33 below the upper edges 18e1, 18e2 which secures the fulcrum 33 of the lever 32 between the upper edges 18e1, 18f1, thereby preventing rotation of the lever 32 around the center longitudinal axis 13 of the center rod 24 from occurring.

[0446] The position of the lever 32, after the fulcrum 33 is urged below the upper edges 18e1, 18f1, maintains a center longitudinal axis of the lever 32 (not shown) in parallel alignment with respect to the longitudinal center axis 11 (FIGS. 1 and 2) of the nail clipper 10. It is never desired that the lever 32 of the nail clipper 10 be able to rotate around the center longitudinal axis 13 of the center rod 24 during transition from the open position to the closed position. Urging the fulcrum 33 of the lever 32 below the upper edges 18e1, 18f1, and between the opposing first and second container sidewalls 18e, 18f, helps to prevent rotation of the lever 32 from occurring during any portion of the transition from the open position to the closed position and, oppositely, from the closed position to the open position. This helps prevent unintended rotation of the lever 32 around the center longitudinal axis 13 of the center rod 24 and it significantly reduces the potential for accidental movement of the nail clipper 10 from occurring during use. Accordingly, the nail clipper 10 helps prevent injury from occurring to the user.

[0447] It is also important to note that as the depth of cut into the nail 8 progresses, the downward force that must be applied to the lever 32 is also proportionally increasing until the nail clipper 10 has been urged into the fully closed position, at which time the downward force is subsequently relaxed. As the applied force upon the lever 32 during use progressively increases, the risk of unwanted rotation by the lever 32 around the center longitudinal axis 13 of the center rod 24 also increases. It should also be noted that only the slightest force is initially required to urge the end 32n of the lever 32 downward. This is because there is no significant resistance provided by the nail 8 to downward movement of the lever 32 until after the lever 32 has been urged in the direction of arrow 50b sufficiently far to bring both of the cutting edges 12a, 14a into contact with opposite sides (i.e., the top and bottom surfaces) of the nail 8. Further downward movement by the lever 32 commences actual cutting of the nail 8 (i.e., penetration of the cutting edges 12a, 14a into the nail 8) which significantly increases resistance to further downward motion by the lever 32.

[0448] Therefore, a significant increase in a magnitude of force that is applied to the lever 32 by the user does not occur until actual cutting of the nail 8 commences. This means that it is easy for the user to initially urge the end 32n of the lever 32 downward enough to lower the fulcrum 33 sufficiently far below the upper edges 18e1, 18f1 to adequately retain the fulcrum 33 between the opposing first and second container sidewalls 18e, 18f before the user must substantially increase the force that is being applied to the lever 32.

[0449] Therefore, after the actual cut of the nail 8 has begun and as the depth of cut into the nail 8 is progressing, the fulcrum 33 is also descending progressively further below the upper edges 18e1, 18f1 and progressively deeper between the opposing first and second container sidewalls 18e, 18f.

[0450] Therefore, as increasing force is progressively being applied to the lever 32 urging it further downward, an increasing ability to retain the center longitudinal axis of the lever 32 in parallel alignment with respect to the longitudinal center axis 11 of the nail clipper 10 is also occurring due to a progressive lowering of the fulcrum 33 between the first and second container sidewalls 18e, 18f. The increasing strength provided by the lower portions of the first and second container sidewalls 18e, 18f (as the fulcrum 33 descends lower) is better able to resist any rotational movement (around the center longitudinal axis 13) that may inadvertently be applied to the end 32n of the lever 32 by the user.

[0451] Therefore, the nail clipper 10 provides proportionately increasing capability and resistance to help prevent unwanted rotation of the lever 32 around the center longitudinal axis 13 of the center rod 24 in proportion to increasing force that is applied to the lever 32 by the user as the depth of cut is progressing. This, in turn, provides a progressively increasing margin of safety when it is needed most during use, which is when the greatest force is being applied to the lever 32.

[0452] Therefore, the nail clipper 10 provides a maximum margin of safety for the user when the potential for injury is at its greatest, and free and easy rotation around the center longitudinal axis 13 of the center rod 24 by the lever 32 when the potential for injury is at its lowest. This rotation is necessary at times when it is desired to urge the nail clipper 10 into the storage position (See FIGS. 5 and 8 and related description, below.) or from the storage position into the open position. Accordingly, the nail clipper 10 provides an optimum engineering design satisfying ease of use and enhanced safety during use not previously available with any prior art dual parallel opposing blade type of nail clipper.

[0453] The disclosed means for preventing rotation of the lever 32 around the center longitudinal axis 13 of the center rod 24 is new for dual parallel opposing blade types of nail clippers, and it provides an important new safety improvement for the nail clipper 10.

[0454] Another benefit provided by the nail clipper 10 is that less force is required to urge lever 32 in the direction of arrow 50b because the lever 32 is prevented from rotating around the center longitudinal axis 13 of the center rod 24. As such only a downward force vector occurs eliminating the wasted force that an additional horizontal force vector would incur. An offset in the lever 32 would create the horizontal force vector. This is a new benefit, not available with any relevant prior art device.

[0455] Referring now primarily to FIGS. 5 and 8 the nail clipper 10 is disposed in the rest position with FIG. 5 showing a right-side view and FIG. 8 showing a front elevational view. The rest position is used for storage or transportation of the nail clipper 10. The nail clipper 10 is especially compact when it is disposed in the rest position and, therefore, occupies minimum space. This is particularly useful when storing the nail clipper 10 in a drawer, placing it on a countertop, a shelf, in a medicine cabinet, or inside a travel bag, container or suitcase.

[0456] To urge the nail clipper 10 from the open position, as shown in FIG. 1, into to the rest position, as shown in FIGS. 5 and 8, the end 32n of the lever 32 is grasped and is rotated 180 degrees around the center longitudinal axis 13 of the center rod 24, as shown by the arc of arrow 50 in FIG. 1. After rotation, a front surface 32k of the U-shaped recessed area 32c is disposed maximally close to the rear wall 19. The end 32n of the lever 32 is then lifted and rotated around a center longitudinal axis of the pin 34 as shown by the arc of arrow 50a (FIG. 1), urging the end 32n toward the distal end 20a of the upper frame member 20, until the end 32n of the lever 32 comes to rest on the top planar surface 20d proximate the distal end 20a the upper frame member 20, as shown in FIG. 5.

[0457] When the lever 32 is disposed as shown in FIG. 5, the nail clipper 10 is disposed in the rest position. In the rest position, the lever 32 is disposed upside down, as compared to its general position in FIG. 1. In the rest position, the center longitudinal axis of the lever 32 also aligns with the center longitudinal axis 11 of the nail clipper 10.

[0458] The U-shaped recessed area 32c includes a pair of upper corners 32p (FIG. 1) that are in alignment with one-another. When the nail clipper 10 is disposed in the rest position, the upper corners 32p are inverted. After the lever 32 has been pivoted along the arc of arrow 50, the lever 32 then pivots along the arc of arrow 50a around the center longitudinal axis of the pin 34 which urges the nail clipper 10 into the rest position. As the lever 32 is urged along the arc of arrow 50a the upper corners 32p urge the upper frame member 20 downward and then relax the downward pressure which allows some upward motion by the upper frame member 20 to occur again.

[0459] As the lever 32 is urged along the arc of arrow 50a, the upper frame member 20 reaches its lowest position approximately when the front surface 32k of the U-shaped recessed area 32c is disposed closest to the lower frame member 18. The distance from the center longitudinal axis of the pin 34 to the front surface 32k of the U-shaped recessed area 32c is limited to ensure that when the lever 32 is urged along the arc of arrow 50a, the upper frame member 20 is not urged lower than the position the upper frame member 20 attains when the nail clipper 10 is disposed in the closed position. In general, distance from the center longitudinal axis of the pin 34 to the front surface 32k of the U-shaped recessed area 32c is sufficiently minimized which, in turn, minimizes the amount the upper frame member 20 is lowered when the lever 32 is urged along the arc of arrow 50a.

[0460] In the rest position, as shown in FIGS. 5 and 8, the upper corners 32p are disposed on the top planar surface 20d of the upper frame member 20. In the rest position the upper frame member 20 is maintained by the upper corners 32p at an elevation that is slightly below the upper edges 18e1, 18f1 of the first and second container sidewalls 18e, 18f. In other words, the upper frame member 20 is somewhat lower when the nail clipper 10 is disposed in the rest position than when the nail clipper 10 is disposed in the open position. Accordingly, when the nail clipper 10 is disposed in the rest position, the upper frame member 20 is applying a slight, but still sufficient upward force to the upper corners 32p. This slight upward force, in turn, causes the lever 32 to pivot around the center longitudinal axis of the pin 34 which, in turn, causes the end 32n of the lever 32 to apply a slight downward force upon the top planar surface 20d proximate the distal end 20a of the upper frame member 20. This downward force exerted by the end 32n of the lever 32 onto the upper planar surface 20d helps maintain the center longitudinal axis of the lever 32 in parallel alignment with respect to the longitudinal center axis 11 of the nail clipper 10 when the nail clipper 10 is disposed in the rest position.

[0461] Additionally, it is important to note that when the nail clipper 10 is disposed in the rest position, as mentioned above, the upper corners 32p are both disposed slightly below the upper edges 18e1, 18f1. The upper corners 32p, being disposed below the upper edges 18e1, 18f1, help to prevent side-to-side motion of the U-shaped recessed area 32c from occurring whenever the nail clipper 10 is disposed in the rest position. Preventing side-to-side motion of the U-shaped recessed area 32c from occurring maintains the center longitudinal axis of the lever 32 in parallel alignment with respect to the longitudinal center axis 11 of the nail clipper 10 whenever the nail clipper 10 is disposed in the rest position. Therefore, once urged into the rest position, the nail clipper 10 remains in the rest position, as shown in FIG. 5, until the end 32n of the lever 32 is again grasped and urged fully in a direction opposite that of arrow 50a. To release the nail clipper 10 from the rest position, the end 32n of the lever 32 is grasped, lifted and urged fully in the opposite direction of arrow 50a. The lever 32 is then rotated 180 degrees around the center longitudinal axis 13 of the center rod 24 in an opposite direction as shown by the arc of arrow 50 until the nail clipper 10 is again disposed in the open position, as shown in FIGS. 1, 3 and 6.

[0462] The nail clipper's 10 ability to remain in the rest position provides an advantage over prior art dual parallel opposing blade types of nail clippers because, by way of contrast, the prior art lever is free to rotate around the prior art center rod when the prior art device is disposed in the prior art rest position. Unintentional rotation of the prior art lever occurs easily which expands the overall size of the prior art nail clipper. This is undesirable for transit or storage. However, the lever 32, and therefore the nail clipper 10, will remain in the rest position after being urged into the rest position unless deliberately urged out of the rest position.

[0463] It is also important to note that parallel alignment of the center longitudinal axis of the lever 32 with respect to the center longitudinal axis 11 of the nail clipper 10 is maintained throughout the duration of movement by the lever 32 along the arc of arrow 50a as well as when movement by the lever 32 is occurring in the opposite direction of arrow 50a. Therefore, whenever the center longitudinal axis of the lever 32 aligns with the center longitudinal axis 11 of the nail clipper 10, as soon as the end 32n of the lever 32 is either raised or lowered, the center longitudinal axis of the lever 32 is maintained in parallel alignment with the center longitudinal axis 11 of the nail clipper 10. During normal use, the end 32n of the lever 32 is not urged upward or downward unless the center longitudinal axis of the lever 32 is in parallel alignment with the center longitudinal axis 11 of the nail clipper 10. Urging the end 32n of the lever 32 upward or downward only occurs, during normal use, when either placing the nail clipper 10 into the rest position, removing the nail clipper 10 from the rest position or when actual cutting of the nail 8 (i.e., transition of the nail clipper 10 from the open to the closed position) is occurring. Therefore, as soon as a force is applied to the end 32n of the lever 32 of the nail clipper 10 during normal use, initial upward or downward displacement by the end 32n of the lever 32 secures and maintains the lever 32 in parallel alignment with respect to the center longitudinal axis 11 of the nail clipper 10.

[0464] Therefore, the nail clipper 10 provides an improvement in safety previously unavailable with all prior art dual parallel opposing blade types of nail clippers. In particular, during normal use (i.e., when the longitudinal axis of the lever 32 is disposed in parallel alignment with the center longitudinal axis 11 of the nail clipper 10), any displacement of the end 32n of the lever 32 away from its normal or quiescent state as occurs when the nail clipper 10 is disposed in the open position or after the lever 32 has been rotated 180 degrees in the direction of arc arrow 50 either upward or downward secures and maintains the lever 32 in parallel alignment with the center longitudinal axis 11 of the nail clipper 10. Therefore, the lever 32 cannot rotate around the center longitudinal axis 13 of the center rod 24 whenever force is applied to the end 32n of the lever 32 in either an upward or downward direction sufficient to vertically displace the end 32n of the lever 32. The lever 32 is maintained in alignment even if a slight horizontal force is applied to the end 32n of the lever 32 after initial vertical (up or down) displacement of the end 32n of the lever 32 has occurred.

[0465] This significantly reduces the likelihood of unintentional displacement of the nail clipper 10 during use which might otherwise accidentally impact and cause injury to the user. It also ensures that whenever force is normally applied to the end 32n of the lever 32 in either an upward or downward direction that the direction of force aligns vertically with respect to the center longitudinal axis 11 of the nail clipper 10. If, by way of contrast during the application of force by the user to the end 32n of the lever 32, the lever 32 were to rotate away from an initial position of parallel alignment with respect to the center longitudinal axis 11 of the nail clipper 10 (Note, This is a condition that cannot occur with the nail clipper 10 but which is discussed only to provide contrast between the improvements provided by the nail clipper 10 and operation of prior art dual parallel opposing blade types of nail clippers that fail to include such improvements), then the force subsequently applied to the end 32n of the lever 32 would include a vertical component (i.e., a vertical force vector) and also a horizontal component (i.e., a horizontal force vector). The horizontal force vector (i.e., a portion of the total force that is applied to the lever 32) increases in magnitude proportionate to the amount of displacement experienced by the end 32n of the lever 32 away from the center longitudinal axis 11 of the nail clipper 10.

[0466] The horizontal component of the force applied (i.e., the horizontal force vector) is not used to displace the end 32n of the lever 32 vertically, either upward or downward, as desired. Rather, the horizontal force vector is, in effect, wasted additional force that is applied to the lever 32 by the user. In other words, the user must apply more force to the end 32n of the lever 32 whenever it is displaced away from the center longitudinal axis 11 in order to create the same magnitude of vertical force (i.e., the same vertical force vector) than is required whenever the center longitudinal axis of the lever 32 is in alignment with the center longitudinal axis 11 of the nail clipper 10 and all of the force applied to the end 32n of the lever 32 is utilized as the vertical force vector (i.e., when there is no horizontal force vector produced). Ensuring that the center longitudinal axis of the lever 32 is maintained in alignment with the center longitudinal axis 11 of the nail clipper 10 during the application of force by the user to the end 32n of the lever 32 prevents displacement of the lever 32, which prevents creation of the horizontal force vector, which minimizes the force that must be applied to the end 32n of the lever 32 to urge the nail clipper 10 from the open position into the closed position (i.e., especially when cutting the nail 8) or to urge the nail clipper 10 into or out of the rest position.

[0467] Therefore, the nail clipper 10 provides an important safety improvement by preventing accidental sudden rotation by the lever 32 around the center longitudinal axis 13 of the center rod 24 and possible displacement of the nail clipper 10 with an increasing risk of causing injury to the user. Additionally, the nail clipper 10 also provides an important improvement in utility by decreasing (i.e., minimizing) the amount of force that has to be applied to the nail clipper 10. Minimizing the magnitude of force applied also lessens the likelihood of slippage by the user, which further promotes safe usage of the nail clipper 10. Both of these important, and surprising, improvements are the result of maintaining the longitudinal axis of the lever 32 in alignment with the center longitudinal axis 11 of the nail clipper 10 whenever the end 32n of the lever 32 is raised or lowered during normal usage.

[0468] It is also especially important to note that the opposing first and second container sidewalls 18e, 18f not only contain the nail clipping 8a, as important as that is, they are also used to prevent rotation of the lever 32 during normal use around the center longitudinal axis 13 of the center rod 24 and, accordingly, to provide the additional improvement in safety and the further additional improvement in minimizing the magnitude of force that is required.

[0469] Although generally not preferred, the nail clipper 10 can be modified in ways not shown to further decrease cost. For example, the opposing first and second container sidewalls 18e, 18f could be eliminated. Doing so would also eliminate the benefits that arise from ensuring that the longitudinal axis of the lever 32 remains in parallel alignment with respect to the center longitudinal axis 11 of the nail clipper 10. Vertical movement of the lever 32 disposes the fulcrum 33 or some portion of the U-shaped recessed area 32c below the upper edges 18e1, 18f1, which maintains alignment. Therefore, elimination of the first and second container sidewalls 18e, 18f would eliminate these improvements, as well. However, numerous other advantages and benefits not currently available with any prior art dual parallel opposing blade type of nail clipper would still be provided by the less expensive version of the nail clipper 10.

[0470] It is, of course, understood by those possessing skill in the mechanical arts, that changing the position of the fulcrum 33 relative to the length of the upper portion 32a of the lever 32 will result in a corresponding change in a mechanical advantage provided by the lever 32. Also as desired, numerous changes in the construction of the lever 32 are possible and are discussed in greater detail, hereinafter. However, it is important to briefly mention now, that by modifying a position and or a shape of the fulcrum 33 to provide the modified fulcrum 33a (See FIGS. 13A, 22, 24, 25 and 60) and/or changes in mechanical advantage can be included to provide a modified version of the nail clipper 10 that requires less force to operate (i.e., a greater mechanical advantage providing a softer feeling version) or, if desired, to require a greater force to operate (i.e., a lesser mechanical advantage providing a firmer feeling version).

[0471] Similarly, the contour of the modified fulcrum 33a can be further modified to include a progressive curvature rather than a single line of contact, as provided by the fulcrum 33 and by the modified fulcrum 33a. The progressive curvature would cause contact between the further modified fulcrum and the top planar surface 20d to progressively move along the top planar surface 20d as the lever 32 that includes the further modified fulcrum is progressively depressed. Accordingly, the further modified fulcrum would act as a variable mechanical advantage type of cam surface that provides a variable mechanical advantage during use. The variable mechanical advantage could include any desired progressive increase or decrease in mechanical advantage as the lever 32 (that includes the further modified fulcrum) is progressively depressed. Preferably, the further modified fulcrum that includes the variable cam would be designed to provide less downward movement and thereby increasingly greater mechanical advantage for the lever 32 as the nail clipper 10 is progressively urged closer toward the closed position. Rounding of the fulcrum 33 may also be used to modify the “feel” of the nail clipper 10 during use.

[0472] This may be useful and used to provide a progressively greater (or lesser, if desired for some reason) mechanical advantage as the depth of cut into the nail 8 progresses, thereby helping to overcome increasing resistance to the cut as the nail clipper 10 is progressively urged from the open position closer toward the closed position. Accordingly, the nail clipper 10 can, by inclusion of the further modified fulcrum, provide an especially smooth cut from start to finish without the need for significantly increasing the magnitude of force that must be applied by the user to complete the cut through the nail 8.

[0473] While many users may prefer a softer feel or a cam-type of further modified fulcrum, decreasing the amount of force that must be applied to the end 32n of the lever 32 may also be especially desirable for cutting especially thick or unusually hard nails 8, which certain people have. For example, toenail fungus can significantly thicken nails. As desired, the distance between the cutting edges 12a, 14a or 52a, 54a is a variable that can be changed for different versions of the nail clipper 10. After complete benefit from reading the instant disclosure and preceding description and review of the drawing figures other desired modifications to the fulcrum 33 or to the modified fulcrum 33a or to the further modified fulcrum will become possible to those having ordinary skill in the art.

[0474] If the nail clipper 10 is disposed in the rest position and it is desired to return the nail clipper 10 to the fully open position for use, the end 32n of the lever 32 is grasped and raised in the direction opposite to arrow 50a. After it has been fully rotated around the center longitudinal axis of the pin 34, the end 32n of the lever 32 is then rotated horizontally around the center longitudinal axis 13 of the center rod 24 in a direction opposite that of arrow 50 until the lever 32 is again disposed as shown in FIG. 1, with the longitudinal axis of the lever 32 in parallel alignment with respect to the center longitudinal axis 11 of the nail clipper 10, at which time the nail clipper 10 is again disposed in the open position and again ready for use.

[0475] FIG. 13 is an enlarged exploded view in perspective of the modified two-piece center rod 124, for replacement use of the center rod 24, as desired, of the nail clipper of FIG. 1. The modified two-piece center rod 124 includes a lower rod portion, identified in general by the reference numeral 128, that, during manufacture of the nail clipper 10, is cooperatively urged together into a bottom of the modified two-piece center rod 124 and, when fully urged together, the lower rod portion 128 preferably locks (i.e., latches) with the modified two-piece center rod 124 in the fully inserted position, which prevents inadvertent separation and removal of the modified two-piece center rod 124 and the accompanying lower rod portion 128 from the nail clipper 10.

[0476] An upper rod portion 126 of the modified two-piece center rod 124 includes a generally U-shaped loop portion 126a at an upper end, thereof. A main body portion, as identified by bracket 126b, extends downward from the U-shaped loop portion 126a so that the overall length of the modified two-piece center rod 124 is approximately the same as the overall length of the center rod 24. The main body portion 126b includes two spaced-apart longitudinal members 126c, 126d that extend downward from opposite ends of the U-shaped loop portion 126a. A pair of enlarged solid cylindrical segments 126e, 126f are each respectively attached to a bottom end of one of the two spaced-apart longitudinal members 126c, 126d. Each of the two spaced-apart longitudinal members 126c, 126d includes an interior wall 126g, 126h that extend the length of the main body portion 126b. A gap exists between the longitudinal members 126c, 126d along the length of the interior walls 126g, 126h. A pair of curved protrusions 126j, 126k extend inward from the interior walls 126g, 126h. The interior walls 126g, 126h also extend over the surface to the curved protrusions 126j, 126k. The shortest distance between the interior walls 126g, 126h (i.e., between the gap) occurs between opposing peaks of the curved protrusions 126j, 126k.

[0477] The lower rod portion 128 includes an enlarged base, identified in general by the reference numeral 128a. The enlarged base 128a includes a pair of enlarged solid extensions 128b, 128c that protrude from opposite sides of the enlarged base 128a. An opposite upper end of the lower rod portion 128 includes a nose section, identified by bracket 128d. A top of the nose section 128d preferably includes an upper concave curvature 128e that, after assembly, is disposed under a center portion of the pin 34. If desired, the upper concave curvature 128e corresponds, generally, with the curvature of the pin 34. However, after assembly, the pin 34 may or may not make physical contact with the upper concave curvature 128e of the nose section 128d. This is because the position of the modified two-piece center rod 124 does not change relative to the bottom frame member 18 after assembly as the upper frame member 20 supplies an upward force to the lever 32 which, in turn, maintains upward pressure on the modified center rod 124 (or on the center rod 24).

[0478] Proceeding downward, the nose section 128d progressively tapers outward to an opposing pair of edges 128j, 128k. The edges 128j, 128k are preferably at the greatest width of the lower rod portion 128. The taper of the nose section 128d allows for easy initial insertion of the lower rod portion 128 into the gap at the bottom of the modified two-piece center rod 124 between the cylindrical segments 126e, 126f during assembly of the nail clipper 10.

[0479] A pair of inward concave curvatures 128f, 128g extend downward from the edges 128j, 128k to a pair of lower edges 128m, 128n. A mid portion, identified by bracket 128h, extends downward from the lower edges 128m, 128n to a top of the enlarged base 128a.

[0480] Preferably the center rod 24 and/or the modified two-piece center rod 124 and/or the lower rod portion 128 are formed of a polymer or other non-metallic material. If desired, the center rod 24 and/or the modified two-piece center rod 124 and/or the lower rod portion 128 can be formed of a metal or any desired sufficiently durable material.

[0481] To assemble the nail clipper 10, the blades 12, 14 are preferably molded into the upper and lower frame members 20, 18 of the nail clipper 10 or are later inserted into the modified dual parallel opposing blade embedded member nail clipper 10a as later discussed (See FIG. 33). If modified discreet upper and lower frame members are used (i.e., if a two-piece modified frame is utilized), the distal ends of the discreet upper and lower frame members are joined together using any preferred method, such as using the clip 702 (FIGS. 27, 27A, 28 and 28A), or by adhesive, double-stick tape, welding, fasteners or any other preferred means. If discreet upper and lower frame members are used to form the modified frame, it is possible to mold the blades 12, 14 in the discreet frame members or to urge the blades 12, 14 into openings 13a, 13b (See FIG. 33 and accompanying description) provided in the frame 16. After the blades 12, 14 are installed or molded (with discreet frame members) in position the cutting edges 12a, 14a are then aligned, the upper blade cutting edge 12a over the lower blade cutting edge 14a. Once aligned, the distal ends of the discreet upper and lower frame members are secured by adhesive, welding the clip 702 or other fastener or by any preferred means. By providing low cost blades 12, 14, lever 32, center rod 24 (or modified center rod 124) and especially low cost discreet frame members that can be quickly and inexpensively secured together while ensuring that the cutting edges 12a, 14a are nearly perfectly aligned, an especially low cost embodiment of the invention is provided. If the blades 12, 14 are inserted into the openings 13a, 13b (i.e., if they are not molded in position), the blades 12, 14 are inserted into the openings 13a, 13b that are provided in the upper and lower frame members 20, 18 at any desired point during assembly. This is possible whether the frame 16 is of one-piece construction or if two-piece discreet frame members based on a variation of the modified dual parallel opposing blade embedded member nail clipper 10a are utilized.

[0482] Referring now to FIG. 12, during manufacture of the nail clipper 10 if the center rod 24 is utilized, the upper end 24b of the center rod 24 is inserted through the lower center rod hole 18p (FIG. 5) provided in the lower segment 18m (FIG. 8) of the lower frame member 18, then through the center hole 22 of the lower blade 14, then through the upper center rod hole 18n provided in the upper segment 18k of the lower frame member 18. The upper end 24b is urged across an air gap between the lower frame member 18 and the upper frame member 20 and through the lower center rod hole 20p provided in the lower segment 20m of the upper frame member 20, through the center hole 22 of the upper blade 12, and through the upper center rod hole 20n provided in the upper segment 20k of the upper frame member 20.

[0483] During assembly, the upper frame member 20 is urged downward an amount sufficient for the upper end 24b to extend above the top planar surface 20d of the upper frame member 20 a desired amount. The U-shaped area 32c of the lever 32 is placed on the top planar surface 20d with the upper end 24b disposed in the U-shaped area 32c. The pin 34 is inserted through one of the aligned pin openings 32d or 32e, through the pin aperture 24c of the center rod 24, and into a remaining one of the aligned pin openings 32d, 32e. Pressure is relaxed which allows the upper frame member 20 to move upward and tension the lever 32 and the center rod 24. The center rod 24 and the lever 32 are now secured in position to a remainder of the nail clipper 10. Friction between the pin 34 and the aligned pin openings 32d, 32e secures the pin 34 in proper position.

[0484] Referring now again to FIG. 13, during manufacture of the nail clipper 10 if the modified two-piece center rod 124 is utilized, the upper rod portion 126 of the modified center rod 124 is inserted through the lower center rod hole 18p, then through the center hole 22 of the lower blade 14, then through the upper center rod hole 18n. The upper rod portion 126 is urged across the air gap between the lower frame member 18 and the upper frame member 20 and through the lower center rod hole 20p, through the center hole 22 of the upper blade 12, and through the upper center rod hole 20n. The upper frame member 20 is urged downward an amount sufficient for the U-shaped loop portion 126a to extend above the top planar surface 20d of the upper frame member 20. The U-shaped area 32c of the lever 32 is placed on the top planar surface 20d with the U-shaped loop portion 126a disposed in the U-shaped area 32c. The pin 34 is inserted through one of the aligned pin openings 32d or 32e, through the gap under the U-shaped loop portion 126a, and into a remaining one of the aligned pin openings 32d, 32e. Pressure is relaxed which allows the upper frame member 20 to move upward and tension the lever 32 and the modified two-piece center rod 124. The modified center rod 124 is temporarily secured in position. The pin 34 is secured in position by friction.

[0485] To complete assembly of the nail clipper 10 utilizing the modified two-piece center rod 124, the nose section 128d is placed in the gap between the cylindrical segments 126e, 126f and urged upward until the concave curvatures 128g, 128f are disposed over the curved protrusions 126k and the 126j, respectively. Additional force is required to overcome increasing resistance in order to urge the lower rod portion 128 fully upward into the modified center rod 124 until the curved protrusions 126k, 126j are disposed in the concave curvatures 128g, 128f. This latches, or locks the lower rod portion 128 to the modified two-piece center rod 124 which prevents disassembly of the nail clipper 10. The enlarged base 128a fills the gap between the cylindrical segments 126e, 126f to provide a smooth modified enlarged head of the fully assembled modified two-piece center rod 124. The modified enlarged head consists of the cylindrical segments 126e, 126f of the modified two-piece center rod 124, the enlarged solid extensions 128b, 128c and a remaining portion of the enlarged base 128a of the lower rod portion 128 that is disposed between the enlarged solid extensions 128b, 128c.

[0486] Continuing to refer to FIG. 13 and referring now also to FIG. 13A, is shown the embedded pin lever 32a1. The embedded pin lever 32a1 is identical to the lever 32 previously described, except the embedded pin lever 32a1 includes the embedded pin 34a1. Additionally, the embedded pin lever 32a1 preferably does not include the aligned pin openings 32d, 32e. The embedded pin 34a1 is preferably molded into opposing sides of the U-shaped recessed area 32c during manufacture of the embedded pin lever 32a1, which would eliminate the need for the aligned pin openings 32d, 32e.

[0487] Therefore, the aligned pin openings 32d, 32e are not necessary as the embedded pin 34a1 becomes an integral part of an assembly that includes the embedded pin lever 32a1 and the embedded pin 34a1. Elimination of the aligned pin openings 32d, 32e provides a cleaner appearance as the exterior surface of the U-shaped recessed area 32c of the embedded pin lever 32a1 is smooth and because the openings for the aligned pin openings 32d, 32e have preferably been eliminated and therefore, are not visible.

[0488] If desired, the embedded pin lever 32a1 can also include the embedded member 32b of the lever 32 (See FIG. 22), or any variation, thereof, to provide increased structural strength for the embedded pin lever 32a1.

[0489] Use of the embedded pin lever 32a1 requires use of the modified two-piece center rod 124 or a variation, thereof. When the embedded pin lever 32a1 is used, the cylindrical segments 126e, 126f of the modified two-piece center rod 124 are sized to ensure that when the cylindrical segments 126e, 126f are urged toward each other and the interior walls 126g, 126h of the cylindrical segments 126e, 126f make contact with each other, that a maximum outside diameter across any portion of the touching cylindrical segments 126e, 126f is less than the inside diameter of the center hole 22 of the blades 12, 14 or any other opening of the nail clipper 10 (or any version) through which the modified two-piece center rod 124 must pass. When the embedded pin lever 32a1 is used, the cylindrical segments 126e, 126f may be made somewhat smaller than when the lever 32 is used. This is because when the embedded pin lever 32a1 is used the cylindrical segments 126e, 126f, must be pinched together during manufacture and pass through the center hole 22 of both blades 12, 14 (and through other openings). However, when the (regular) lever 32 is used, the cylindrical segments 126e, 126f do not have to pass through the center holes 22 or other openings as the smaller diameter upper rod portion 126 and the smaller diameter main body portion 126b can instead be inserted from the bottom of the nail clipper 10 upwards, as described earlier, during assembly.

[0490] Therefore, during assembly of the nail clipper 10 when utilizing the modified two-piece center rod 124 and the embedded pin lever 32a1, the modified two-piece center rod 124, absent the lower rod portion 128, is placed over the embedded pin 34a1 and urged downward as far as it will go until an underside of the U-shaped loop portion 126a is resting on top of the embedded pin 34a1. The cylindrical segments 126e, 126f are then grasped and pinched together. The embedded pin lever 32a1 is placed atop the upper frame member 20 with the pinched-together cylindrical segments 126e, 126f of the upper rod portion 126 disposed above and in alignment with the center hole 22 of the upper blade 12.

[0491] The embedded pin lever 32a1 along with the upper rod portion 126 are urged downward until the cylindrical segments 126e, 126f emerge below the bottom surface 20c of the upper frame member 20. The cylindrical segments 126e, 126f are again pinched together and the embedded pin lever 32a1 along with the upper rod portion 126 are urged downward until the cylindrical segments 126e, 126f pass through and emerge below the bottom planar surface 18c of the lower frame member 18. The position of the upper rod portion 126 is maintained while the nose section 128d of the lower rod portion 128 is placed between the cylindrical segments 126e, 126f and urged upward until the enlarged base 128a of the lower rod portion 128 is flush with and disposed between the cylindrical segments 126e, 126f.

[0492] The pair of concave curvatures 128f, 128g of the lower rod portion 128 each engage with one of the pair of curved protrusions 126j, 126k sufficient to secure the lower rod portion 128 in a position of cooperative engagement with the upper rod portion 126 and thereby complete assembly of the modified two-piece center rod 124. This helps to prevent disassembly of the nail clipper 10 after assembly has been completed.

[0493] The lower rod portion 128 also urges the cylindrical segments 126e, 126f sufficiently far apart to maintain position of the cylindrical segments 126e, 126f under the bottom planar surface 18c of the lower frame member 18 and, accordingly, prevent further upward motion of the modified two-piece center rod 124 with respect to the lower frame member 18 during use. The enlarged base 128a disposed between the cylindrical segments 126e, 126f also creates an attractive finished appearance for a bottom of the modified two-piece center rod 124 assembly that includes the upper rod portion 126 and the lower rod portion 128 properly inserted, as described above.

[0494] Referring now to FIG. 33, is shown an enlarged front view of the modified dual parallel opposing blade embedded member nail clipper 10a, hereinafter referred to as “the modified opening nail clipper 10a”. The modified opening nail clipper 10a is shown with the blades 12, 14, the lever 32, the center rod 24, and the pin 34 removed to better reveal the difference between the modified opening nail clipper 10a and the nail clipper 10.

[0495] With the modified opening nail clipper 10a, the blades 12, 14 are not molded into the upper and lower frame members 20, 18. During molding of the upper and lower frame members 20, 18, a mold member (not shown) extends into the upper and lower frame members 20, 18 where the horizontal portions 30 of the blades 12, 14 are to be later inserted. After forming the upper and lower frame members 20, 18, the mold member is removed providing the upper opening 13a beginning at the front end 20b and extending into the upper frame member 20 and providing the lower opening 13b beginning at the front end 18b and extending into the lower frame member 18.

[0496] At any desired point during manufacture, the horizontal portions 30 of the blades 12, 14 (or the modified blades 52, 54) are urged into the upper and lower openings 13a, 13b, respectively. The upper and lower openings 13a, 13b are preferably sized to create friction between the interior of the upper and lower openings 13a, 13b and the exterior of horizontal portions 30 of the blades 12, 14 as the horizontal portions 30 are urged into the upper and lower openings 13a, 13b. The friction secures the blades 12, 14 in position. After insertion, some of the polymer (or other non-metallic material used to form the upper and lower frame members 20, 18) may flow into the securing holes 26 and/or into the side indentations 28 to additionally help secure the blades 12, 14 in position. Heat produced by the friction during insertion of the blades 12, 14 into the upper and lower openings 13a, 13b may temporarily increase the rate of flow of the surrounding polymer into the securing holes 26 and/or the side indentations 28, thereby further helping to secure the blades 12, 14 in position.

[0497] Accordingly, the upper and lower openings 13a, 13b are illustrative of an alternate method for embedding the blades 12, 14 (or the modified blades 52, 54) into the modified opening nail clipper 10a during manufacture.

[0498] Referring now to FIG. 19 is shown the second modified dual parallel opposing blade embedded member nail clipper 200, hereinafter referred to as “the second modified nail clipper 200.” The second modified nail clipper 200 is substantially identical to the nail clipper 10, except for modifications involving the shorter center rod 224 that is provided with the second modified nail clipper 200. The shorter center rod 224 includes the modified enlarged head 224a that bears directly upon the top blade surface 14f of the inverted lower blade 14. If desired (as shown), polymer surrounds the modified enlarged head 224a. It may be possible to include the shorter center rod 224 as an extension (i.e., as a vertical elongated protrusion) of the second modified lower frame member 218 during molding of the second modified nail clipper 200. The shorter center rod 224 would then be formed (i.e., molded) as an integral part of the second modified lower frame member 218. If molded as an integral part of the second modified lower frame member 218, the modified enlarged head 224a would be eliminated the upward second compressive force would be conveyed through the vertical elongated protrusion or extension to the second modified lower frame member 218 and thereby to the bottom blade surface 14b. If desired, and if the shorter center rod 224 is used, it can be formed of a metal or other sufficiently durable material and molded in place passing through the center hole 22 of the lower blade 14 during molding of the second modified lower frame member 218.

[0499] Referring now to FIG. 20 is shown the third modified dual parallel opposing blade embedded member nail clipper 300, hereinafter referred to as “the third modified nail clipper 300.” The third modified nail clipper 300 is substantially identical to the second modified nail clipper 200, except for the lower frame opening 302 that is provided in a bottom of the third modified lower frame member 318. This allows insertion of the shorter center rod 224 into the lower frame opening 302 and upward into the third modified nail clipper 300 which may improve ease of manufacturing and lower assembly cost.

[0500] Referring now to FIG. 21 is shown the fourth modified dual parallel opposing blade embedded member nail clipper 400, hereinafter referred to as “the fourth modified nail clipper 400.” The fourth modified nail clipper 400 is similar to the nail clipper 10 except for changes affecting the fourth modified upper frame member 420. The shorter center rod 224 of the second modified nail clipper 200 or of the third modified nail clipper 300 may be used with the fourth modified nail clipper 400. A portion of the fourth modified upper frame member 420 disposed above the top blade surface 12f of the horizontal portion 30 of the upper blade 12 has been removed in the area 420a, leaving the top blade surface 12f exposed. As a result, the fulcrum 33 of the lever 32 bears down directly upon the top blade surface 12f of the upper blade 12. The first compressive force, supplied by the fulcrum 33 of the lever 32 during use, urges the upper blade 12 downward. As the upper blade 12 is urged downward, the upper blade 12 urges a remainder of the fourth modified upper frame member 420 downward.

[0501] The modifications shown in FIGS. 19-21 also greatly reduce the amount of shear experienced by the frame 16 and, thereby, provide many of the benefits previously and subsequently described, herein.

[0502] Referring now to FIG. 22 is shown the optional reinforcing embedded member 32b in dashed lines. The reinforcing embedded member 32b, if included, is preferably molded into the lever 32, and, thereby, embedded in the lever 32. A forward portion 32b1 of the reinforcing embedded member 32b is disposed under a pair of first and second aligned pin openings 32d, 32e to increase strength and prevent damage to the U-shaped recessed area 32c when the lever 32 is urged downward during cutting of the nail 8. The U-shaped recessed area 32c extends forward of the upper portion 32a of the lever 32, as shown in FIG. 22 by bracket 32c. The reinforcing embedded member 32b includes any preferred size or shape as long as it is generally contained within an interior of the lever 32 for optimum appearance. Use of the optional embedded member 32b contained (i.e., molded) within a polymer exterior of the lever 32 allows for greater variety in sculpting the overall shape, appearance and functioning (by including the rounded or cam fulcrum 33 previously discussed) of the lever 32 while providing nearly the same strength as would occur if the lever 32 were, instead, formed entirely of a metal. The reinforcing embedded member 32b can extend as far up the upper portion 32a of the lever 32, as desired. The reinforcing embedded member 32b is formed of any desired material, including any metal or alloy or desired non-metallic material. It is preferred, but not mandatory, that as much of the lever 32 is formed of a polymer or other non-metallic material, as possible. If desired, the lever 32 could be formed entirely of a metal.

[0503] Referring now also to FIG. 24 is shown in perspective the first modified lever 32f with the modified fulcrum 33a that may be used instead of the lever 32 with the nail clipper 10 or any similar embodiment of the invention, as desired. The first modified lever 32f is shown with an optional carrying hole 32g for attachment to a key chain (not shown) or hanging where desired. The carrying hole 32g can also be included with the lever 32, if desired. The first modified lever 32f, as shown in FIG. 24, is preferably formed entirely of plastic. The first modified lever 32f includes an additional thickness of plastic proximate the modified fulcrum 33a to provide additional strength and rigidity in this area. The first modified lever 32f also includes a second additional thickness of plastic proximate a mid-portion 32h to provide additional strength and rigidity in this area. Additional optional components that significantly help improve the process and end-result of cutting the nail 8 are also included in the first modified lever 32f and are later described in greater detail.

[0504] Referring now to FIG. 25, the second modified lever 32f1 is shown that includes the optional metallic (or formed of any desired material) embedded reinforcing elongated member 32j embedded therein. The elongated member 32j is shown in dashed lines. A lower portion of the elongated member 32j is disposed below the first and second aligned pin openings 32d, 32e for increased support and strength during use. The elongated member 32j is included in the second modified lever 32f1, as necessary, to provide additional strength, rigidity and durability to the second modified lever 32f1. It is also possible to include a further modified embedded member (not shown) in a variation made to the axially pivoting lever 1132. The axially pivoting lever 1132 is described later.

[0505] Referring now momentarily to FIGS. 14, 15, 17 and 23 additional detail of the modified blades 52, 54 is shown. FIG. 17 shows a partial view taken along line 17-17 of FIG. 15 showing the curvature of the modified cutting edges 52a, 54a. Additionally, the cutting edges 52a, 54a are shown disposed along a center of the thickness of the modified blades 52, 54, illustrating the cross-sectional profile of image 14d1 of FIG. 14. Any of the cutting edges 12a, 14a, 52a, 54a can include any desired cross-sectional shape.

[0506] FIG. 23 is an enlarged top view of the fifth modified dual parallel opposing blade embedded member nail clipper 500, hereinafter referred to as “the fifth modified nail clipper 500.” The lever 32 and the center rod 24 (or the modified two-piece center rod 124) have been removed for improved clarity of construction. The fifth modified nail clipper 500 is identical to the nail clipper 10 (and view shown in FIG. 2) except the fifth modified nail clipper 500 also includes the curved modified blades 52, 54 of FIGS. 15 and 17 instead of the blades 12, 14, and the fifth modified nail clipper 500 includes the curved modified safety bumper 39a that better corresponds with the curvature of the modified blades 52, 54 but which is otherwise similar to the safety bumper 39 described before. The lower modified blade 54 is not visible in FIG. 23 because it is inverted and disposed directly below the upper modified blade 52. The curved modified blades 52, 54 are expected to be preferred for many embodiments of the invention due to the benefits provided by the curvature of the modified cutting edges 52a, 54a, as previously described. However, the blades 12, 14 may be easier or less expensive to manufacture than the modified blades 52, 54 and may also be used in any similar alternate embodiment of the invention, as desired.

[0507] Referring now to FIG. 26 is shown the sixth modified dual parallel opposing blade embedded member nail clipper 600, hereinafter referred to as “the sixth modified nail clipper 600.” The sixth modified nail clipper 600 is similar to the nail clipper 10 and the cross-sectional view shown in FIG. 9. However, the sixth modified nail clipper 600 includes the modified U-shaped upper member 620 that includes a generally inverted cross-sectional U-shape and an opposing pair of vertical members 602, 604 that are integrally formed with the modified U-shaped upper member 620 during molding (or by any other preferred manufacturing method).

[0508] The vertical members 602, 604 extend the overall or maximum vertical height (i.e., thickness) of the modified U-shaped upper member 620 as compared to the upper frame member 20. If desired, the position of a modified top planar surface 620d of the modified U-shaped upper member 620 can be disposed at a greater elevation above a modified lower frame member 618 than with the nail clipper 10 because at least a lower portion of the vertical members 602, 604 would be disposed between an opposing pair of modified container sidewalls 618e, 618f, which would help to ensure that the modified U-shaped upper member 620 remains properly aligned with respect to the modified lower frame member 618 (i.e., between the modified container sidewalls 618e, 618f) as the modified U-shaped upper member 620 is urged up and down during use. This can be used to increase the distance between the cutting edges 12a, 14a (not shown) of the blades 12, 14 when the sixth modified nail clipper 600 is disposed in the open position. This would allow for insertion of a thicker example of the nail 8 for cutting, such as would occur if toenail fungus significantly increased the thickness of the nail 8.

[0509] Modified ledges 636a, 636b are optionally included in the modified lower frame member 618. A pair of lower ends 602a, 604a of the vertical members 602, 604 preferably begin to contact the top surfaces of the modified ledges 636a, 636b when the sixth modified nail clipper 600 is disposed in the closed position, thereby providing the benefits previously described for the ledges 36a, 36b.

[0510] Referring now to FIG. 27, 27A and FIG. 28, 28A the modified spring clip nail clipper 700, is shown. The modified spring clip nail clipper 700 is a seventh type of a modified nail clipper that is constructed in a manner consistent with the cardinal teachings of the invention.

[0511] To illustrate an especially simple and low cost embodiment of the invention, the modified spring clip nail clipper 700 does not include sidewalls. Therefore, the modified spring clip nail clipper 700 would not be able to capture any nail clippings 8a, therein. If capture of the nail clippings 8a is desired it is, of course, possible to include further modified sidewalls (not shown) attached to either a lower clip frame member 718 or attached to an upper clip frame member 720 or partially attached to both the lower clip frame member 718 and the upper clip frame member 720 (i.e., to include half [or a portion] of the further modified sidewalls extending upward from the lower clip frame member 718 and a remaining half [or a remaining portion] of the further modified sidewalls extending downward from the upper clip frame member 720 so that the upper and lower clip frame members 720, 718 overlap each other or make contact in the closed position). Similar modification to the upper and lower clip frame members 720, 718 to include the further modified sidewalls is possible for various embodiments of the invention including certain embodiments identified by reference numerals 10, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 2000 and other variations, thereof. To further simplify design and possibly further lower cost, the modified spring clip nail clipper 700 does not include any version of a safety bumper. If desired, the modified spring clip nail clipper 700 could, of course, also include the safety bumper (See FIG. 2, safety bumper 39 and FIG. 23, curved modified safety bumper 39a).

[0512] The front portion of the modified spring clip nail clipper 700 is either identical or similar to any embodiment of the current invention as previously described. As preferred, the front portion can include any variation described herein or any possible variation of the current invention. The rear portion of the modified spring clip nail clipper 700 can also be further modified, as desired.

[0513] The modified spring clip nail clipper 700 includes the spring clip 702, as briefly mentioned earlier. The spring clip 702 provides an important first benefit and an unexpected important second benefit, as described below.

[0514] As shown, the lower clip frame member 718 includes a top planar surface 718d. To minimize cost, the lower clip frame member 718 does not include a further modified container sidewall (not shown); however, inclusion of any preferred type of the further modified container sidewall is possible for use with the modified spring clip nail clipper 700, as discussed above.

[0515] A generally spherical protrusion 706 extends upward from an upper planar upper surface 704 of the lower clip frame member 718. The upper clip frame member 720 includes a modified bottom surface 720c and a lower planar surface 708 (See FIGS. 27A and 28A). The lower planar surface 708 includes a spherical recess 710 into which the protrusion 706 is disposed when the lower planar surface 708 of the upper clip frame member 718 is placed atop the upper planar upper surface 704 of the lower clip frame member 718 (See FIGS. 27A and 28A).

[0516] The lower clip frame member 718 and the upper clip frame member 720, together, form the modified spring clip frame 716 of the modified spring clip nail clipper 700. After assembly, the modified spring clip frame 716 of the modified spring clip nail clipper 700 includes a U-shape when viewed from the side. If desired, the shape of the upper and lower clip frame members 720, 718 could be modified to include a V-shape or other desired shape when viewed from the side.

[0517] An upper arcuate recess 712 is provided in the upper clip frame member 720. A lower arcuate recess 714 is provided in the lower clip frame member 718. The width of the upper and lower arcuate recesses 712, 714 is variable and can be as wide as the upper and lower clip frame members 720, 718 or, if desired, the upper and lower arcuate recesses 712, 714 may include a lesser width that does not extend fully across the width of the upper and lower clip frame members 720, 718. Not having the upper and lower arcuate recesses 712, 714 visible when viewing the modified spring clip nail clipper 700 from the side may be deemed aesthetically preferable. The width of the upper and lower arcuate recesses 712, 714 are sized to accept the spring clip 702, therein.

[0518] During manufacture, the upper clip frame member 720 and the lower clip frame member 718 are manufactured as two separate component parts (pieces), preferably by molding. The upper clip frame member 720, when complete, is an assembly that also includes the upper blade 12 or the upper clip frame member 720 as an assembly could instead include the upper modified blade 52 (not shown in FIG. 27 or FIG. 28). The lower clip frame member 718, when complete, is an assembly that similarly includes the lower blade 14 or the lower clip frame member 718, as an assembly could instead include the lower modified blade 54 (not shown in FIG. 27 or FIG. 28) to match the upper modified blade 52, if the upper modified blade 52 is included in the upper clip frame member 720 as an assembly.

[0519] The upper clip frame member 720 is placed atop the lower clip frame member 718 while ensuring that the protrusion 706 is disposed inside the spherical recess 710, and while also ensuring that the plane of the lower planar surface 708 is disposed on top of the plane of the upper planar upper surface 704, as shown in FIG. 27. The spring clip 702 is then urged in the direction of arrow 715 (FIG. 27) so that an upper end 702a of the spring clip 702 and a lower end 702b of the spring clip 702 simultaneously enter and are urged fully into the upper arcuate recess 712 and into the lower arcuate recess 714, as shown in FIG. 27.

[0520] The first benefit provided by the spring clip 702 is that it quickly and inexpensively can be inserted, as described above, to secure the upper clip frame member 720 and the lower clip frame member 718 together. This decreases both the time and the cost of manufacture for the modified spring clip nail clipper 700. The second benefit simultaneously provided by the spring clip 702 is that it supplies a force, as described below, that helps urge the modified spring clip nail clipper 700 into the open position. This is useful in that it allows the use of different and possibly less flexible (i.e., having less hysteresis or less elastomeric properties) or less expensive grades of plastic (or other non-metallic material) for construction of the upper clip frame member 720 and the lower clip frame member 718 because hysteresis (i.e., inherent elasticity) of these components is not being significantly relied-upon to urge the modified spring clip nail clipper 700 into the open position. Therefore, a stiffer plastic, for example, could be utilized and may even be preferred, while still ensuring that the modified spring clip nail clipper 700 will be urged into the open position after pressure is released from the lever 32 by force supplied from the spring clip 702. This is described in greater detail, below.

[0521] Once inserted, the spring clip 702 supplies a compressive force urging a rear of the upper clip frame member 720 in the direction of arrow 722 and urging a rear of the lower clip frame member 718 in the direction of arrow 724. The center rod 24, the pin 34 and the lever 32 are then added to complete assembly of the modified spring clip nail clipper 700.

[0522] The compressive force supplied by the spring clip 702 urges and maintains the modified spring clip nail clipper 700 in the open position unless the lever 32 is depressed or unless the modified spring clip nail clipper 700 is disposed in the rest position (not shown). The spring clip 702 also maintains the upper and lower clip frame members 720, 718 together in a position of cooperation as shown in FIG. 27 and FIG. 28. The modified spring clip nail clipper 700 is disposed into the rest position in a manner similar to that as previously described for the nail clipper 10. When the modified spring clip nail clipper 700 is disposed as shown in FIG. 27, the modified spring clip nail clipper 700 is disposed in the open position.

[0523] During use, the lever 32 is depressed until the modified spring clip nail clipper 700 is disposed in the fully closed position (i.e., after having cut the nail 8), as shown in FIG. 28. As the lever 32 is being depressed in the direction of arrow 750, the upper clip frame member 720 and the lower clip frame member 718 pivot with respect to each other around the spherical recess 710 and around the spherical protrusion 706. Depressing the lever 32 progressively urges the upper end 702a of the spring clip 702 and the lower end 702b of the spring clip 702 further apart than when the modified spring clip nail clipper 700 is disposed in the open position. Therefore, during cutting the spring clip 702 supplies a progressively greater force in the direction of arrows 722 and 724 which, upon release of the lever 32, helps urge the modified spring clip nail clipper 700 back into the open position.

[0524] It is generally preferred to include a second spherical protrusion (not shown) beside the spherical protrusion 706 or to include the second spherical protrusion on the opposite assembly (i.e., to include the second spherical protrusion on the upper clip frame member 720), and to also include a second recess (not shown) beside the recess 710 or to include the second recess on the opposite assembly (i.e., to include the second recess on the lower clip frame member 718). This creates a pivot axis that extends between a center of the two spherical protrusions 706 which helps to ensure that a forward portion of the upper clip frame member 720 is disposed in a parallel spaced-apart relationship with respect to a forward portion of the lower clip frame member 718 when the two clip frame members 718, 720 are disposed as shown in FIG. 27. By including the (one) spherical protrusion 706 and the (one) recess 710 side-by-side on both the upper clip frame member 720 and also on the lower clip frame member 718 it is possible for the lower clip frame member 718 and the upper clip frame member 720 to be manufactured as identical component parts, which would significantly decrease manufacturing cost.

[0525] Also shown in dashed lines is an optional rear extension 726 that is attached to a rear of the lower clip frame member 718 and which extends upward. If desired, the optional rear extension 726 could be modified so that it was attached to a rear of the upper clip frame member 720 and oriented so it instead extended downward. As best seen by a comparison of FIG. 27 and FIG. 28, with emphasis on FIG. 28, the rear extension 726, if included, provides a covering that extends over the space between the upper planar surface 704 and the lower planar surface 708. This prevents inadvertent insertion of any skin or flesh between the upper planar surface 704 and the lower planar surface 708 when the modified spring clip nail clipper 700 is disposed in the closed position which could later result in pinching of the skin or flesh when the modified spring clip nail clipper 700 is returned to the open position.

[0526] Referring now also to FIG. 30 is shown an enlarged cross-sectional view taken through the center rod 24 and looking toward the rear of the eighth modified dual parallel opposing blade embedded member nail clipper 800, hereinafter referred to as “the eighth modified nail clipper 800.” The eighth modified nail clipper 800 is disposed in the open position.

[0527] The eighth modified nail clipper 800 is similar to the nail clipper 10 except that certain of the component parts of the eighth modified nail clipper 800 are inverted in their positioning with respect to the nail clipper 10. See also FIG. 31 which includes an enlarged full (i.e., complete) bottom view of the eighth modified nail clipper 800.

[0528] The eighth modified nail clipper 800 includes the inverted upper frame member 820 that includes the pair of first and second spaced-apart inverted sidewalls 820e, 820f that are an integral part of the inverted upper frame member 820. Preferably, the eighth modified nail clipper 800 is molded from a desired polymer and the inverted sidewalls 820e, 820f are molded to become integral with respect to the inverted upper frame member 820. Therefore, the inverted sidewalls 820e, 820f extend downward from the inverted upper frame member 820 and provide a substantial increase in strength and stiffness of the inverted upper frame member 820. The upper blade 12 is included in the inverted upper frame member 820 and the lower blade 14 is included in the inverted lower frame member 818. Only the horizontal portions 30 of the blades 12, 14 are visible in FIG. 30.

[0529] During depression of the lever 32, the fulcrum 33 (not shown in FIG. 30 or FIG. 31) of the lever 32 bears down upon a modified top planar surface 820d of the inverted upper frame member 820. The downward force applied to the modified top planar surface 820d applies a downward compressive force to the plastic of the inverted upper frame member 820 above the horizontal portion 30 of the upper blade 12 that is transferred through the plastic to the horizontal portion 30 of the upper blade 12. The downward compressive force prevents the upper blade 12 and the inverted upper frame member 820 from being urged away (i.e., upward) from the inverted lower frame member 818.

[0530] As the lever 32 is depressed, the pin 34 urges (displaces) the center rod 24 upward as the U-shaped recessed area 32c of the lever 32 is raised. This is different than operation of the nail clipper 10 where the center rod 24 of the nail clipper 10 does not move upward during use (i.e., cutting of the nail 8). The enlarged head 24a of the center rod 24 applies an upward compressive force to a modified bottom planar surface 818c of the inverted lower frame member 818, which applies an upward compressive force to the plastic under the horizontal portion 30 of the lower blade 14 and transfers the upward compressive force to the lower blade 14. The inverted lower frame member 818 is urged upward in response to the upward compressive force until the eighth modified nail clipper 800 is disposed in the closed position. When the eighth modified nail clipper 800 is disposed in the closed position the cutting edges 12a, 14a abut (i.e., contact) one-another and/or a modified top planar surface 818d of the inverted lower frame member 818 makes contact with one or a pair of inverted ledges 836a, 836b that are optionally included in the inverted sidewalls 820e, 820f of the inverted upper frame member 820. If a smoother bottom surface is desired, the enlarged head 24a can be embedded into the inverted lower frame member 818 consistent with the teachings of FIG. 19 or 20 to provide the smoother bottom surface.

[0531] FIG. 31 shows how the inverted lower frame member 818 is attached (i.e., molded) to an inverted rear wall 819 at the rear of the eighth modified nail clipper 800. A remaining portion of the inverted rear wall 819 is molded (i.e., formed) integrally with the inverted upper frame member 820. A rear (or distal end) of the inverted sidewalls 820e, 820f are also molded to the inverted rear wall 819. The inverted sidewalls 820e, 820f increase the stiffness of the inverted upper frame member 820. Therefore, during use the inverted upper frame member 820 experiences very little flexing. As a result, and opposite to that of the nail clipper 10, the inverted lower frame member 818 experiences most of the flexing as the lower blade 14 of the inverted lower frame member 818 is urged upward until the eighth modified nail clipper 800 is disposed in the closed position. Because of the added stiffness provided by the inverted sidewalls 820e, 820f, it may be possible to shorten the horizontal portion 30 of the upper blade 12 as much as desired.

[0532] By way of comparison, during use of the nail clipper 10 the upper frame member 20 experiences almost all of the flexing that occurs as the upper frame member 20 is urged downward toward the lower frame member 18. As the upper frame member 20 is urged downward it descends deeper between the first and second container sidewalls 18e, 18f. By way of contrast, during use of the eighth modified nail clipper 800, the inverted lower frame member 818 experiences the greater portion of flexing and is urged upward toward the inverted upper frame member 820. As the inverted lower frame member 818 is urged upward it progressively rises deeper between the spaced-apart inverted sidewalls 820e, 820f of the inverted upper frame member 820.

[0533] The eighth modified nail clipper 800 illustrates how certain embodiments can be inverted and still adhere to the cardinal teachings of all embodiments of the current invention that include the embedded horizontal portions 30 of at least one of the opposing blades 12, 14 in vertical alignment with at least one of the opposing forces that are simultaneously applied to the upper and lower frame members 20, 18. Therefore, every embodiment of the instant invention significantly reduces the amount of shear that is experienced by the upper and lower frame members 20, 18 which, in turn, allows for the use of polymer or other non-metallic material for construction of the frame 16 (i.e., the greater portion of the upper and lower frame members 20, 18). Alternative methods for embedding other members to provide a similar benefit as the horizontal portion 30 are also described later.

[0534] Referring now to FIGS. 32, 32A and 32B is shown in FIG. 32 an enlarged cross-sectional view taken through the center rod 24 and looking toward the rear of the ninth modified dual parallel opposing blade embedded member nail clipper 900, hereinafter referred to as “the ninth modified nail clipper 900.” The ninth modified nail clipper 900 includes the floating upper frame member 920 and the floating lower frame member 918 that are each attached at their respective distal ends to a top and a bottom, respectively, of the modified vertical floating rear wall 919. FIG. 32 is a view taken in cross-section through the center rod 24 and looking rearward. FIG. 32A is an enlarged top view of the ninth modified nail clipper 900 of FIG. 32 in an open position after its assembly is complete. FIG. 32B is a smaller scale bottom view of the ninth modified nail clipper 900 of FIG. 32.

[0535] The ninth modified nail clipper 900 includes the pair of first and second spaced-apart floating container sidewalls 919e, 919f that are an integral part of the floating rear wall 919 (i.e., the floating container sidewalls 919e, 919f are attached at their distal ends to the floating rear wall 919). The floating container sidewalls 919e, 919f extend forward from the floating rear wall 919. The floating upper frame member 920 and the floating lower frame member 918 are preferably disposed (at least partially) between the floating container sidewalls 919e, 919f when the ninth modified nail clipper 900 is disposed in the open position, as shown in FIGS. 32, 32A and 32B.

[0536] Referring momentarily to FIG. 32A, a pair of first gaps 902a, 902b extend along the longitudinal length of the floating upper frame member 920 on each side, thereof. The first gaps 902a, 902b begin proximate a top of the floating rear wall 919 where the floating upper frame member 920 is attached to the floating rear wall 919. The first gaps 902a, 902b extend forward up to the front of the of the floating upper frame member 920.

[0537] Referring momentarily to FIG. 32B, a pair of second gaps 904a, 904b extend along the longitudinal length of the floating lower frame member 918 on each side thereof. The second gaps 904a, 904b begin proximate a bottom of the floating rear wall 919 where the floating lower frame member 918 is attached to the floating rear wall 919. The second gaps 904a, 904b extend forward up to the front of the of the floating lower frame member 918 and up to the front of the floating container sidewalls 919e, 919f.

[0538] The floating upper and lower frame members 920, 918 and the floating sidewalls 919e, 919f are, therefore, each attached at their respective distal ends to the floating rear wall 919. The floating upper frame member 920 is urged downward in the direction of arrow 902 (FIG. 32) when the lever 32 is depressed and upward in the direction of arrow 904 (FIG. 32) when the lever 32 is released. The floating lower frame member 918 is urged upward in the direction of arrow 904 when the lever 32 is depressed and downward in the direction of arrow 902 when the lever is released. Therefore, the floating upper and lower frame members 920, 918 flex up or down relative to the floating sidewalls 919e, 919f during use.

[0539] During use, the fulcrum 33 (not shown) of the lever 32 applies a downward compressive force to a floating top planar surface 920d the floating upper frame member 920 which is urged downward in response to that force. Upward movement by the U-shaped recessed area 32c of the lever 32 and by the pin 34 also urges the center rod 24 upward as the floating upper frame member 920 is being urged downward. As the center rod 24 is urged upward, a compressive force is applied by the enlarged head 24a of the center rod 24 to a bottom planar surface 918c of the floating lower frame member 918 which urges the floating lower frame member 918 upward until the ninth modified nail clipper 900 is disposed in the closed position.

[0540] The floating container sidewalls 919e, 919f do not flex relative to the floating rear wall 919 as the floating upper and lower frame members 920, 918 are urged toward each other (or away from each other) because no vertical compressive force is applied to the floating sidewalls 919e, 919f during use.

[0541] It is possible to create a frame assembly of the ninth modified nail clipper 900, in which the frame assembly includes the floating rear wall 919, the floating upper and lower frame members 920, 918 (with or without the blades 12, 14) and including the optional floating container sidewalls 919e, 919f as an integral one-piece molded component. The blades 12, 14 may be attached later or included during molding of the floating upper and lower frame members 920, 918 and the floating rear wall 919, as desired. Similarly, the frame 16 of the nail clipper 10 or most embodiments, thereof, that include a version of the one-piece frame 16, can be similarly molded as a one-piece component.
