Abstract
Nail clipper of the leaf spring type in which the leaf spring elements of the clipper are superimposed and have facing inturned cutting edges at their proximate ends and are riveted together at their distal ends. A post extending through the leaf spring elements close to the proximate ends thereof forms a reaction member for a lever moving the leaf spring elements together to effect a clipping operation. Extending partially about the post and facing the cutting edges of the leaf spring elements is a nail clipping decelerator and accumulator formed to prevent the flying of nail clippings beyond opposite edges of the clipper and to accumulate the clippings for disposal by opening the clipper and shaking it in a sideways direction. The clippings decelerator and accumulator has arcuate faces extending from opposite sides of the post and cooperating with a recessed arcuate face of the post and also has closed sides extending from the arcuate faces toward the clipping edges of the clipper and has a ledge extending along the tops of the arcuate faces as well as a similar ledge engaging the bottom of the lowermost leaf spring element, to decelerate and accumulate the clippings for the entire width of the lowermost leaf spring element until necessary to dispose of the clippings by opening the clipper blades and shaking the clipper from side to side, with the decelerator and accumulator facing in a downward direction.

Description
Background of the Invention
Nail-clipping devices in which the clippings are intended to be retained to the device and held from scattering during clipping of the fingernails or toenails, and collected for disposal, have heretofore been known. Such nail clippers of the type fitting in the pocket or purse usually utilize two superimposed spring steel elements riveted together at their distal ends and having inturned sharpened cutting edges at their opposite ends in which the steel elements are biased apart when riveted together, with the top element extending from the rivet angularly away from the bottom element, to bias the cutting edges of the elements away from each other at the proximate ends of the spring steel elements, to enable the fingernail or toenail to be placed along the lower sharpened cutting edge and be trimmed as said cutting edges are brought together. Such clippers have also had retaining means for the clipped nails which extend along the top and lower spring steel elements toward a point where the spring steel elements come together. While such clippings retainers and collectors may prevent scattering of the nail fragments, they materially add to the cost and bulk of the clipper and are objectionable in that the clippings frequently fly out the sides of the clipper and when this does not happen the user of the clipper frequently lets the clippings accumulate in the clipper rendering it difficult to clip the nails when the retainer is filled with clippings.
While the efficiency of clipping can be increased upon emptying the clippings from the retainer, it is usually difficult to thoroughly clean the retainer of nail clippings, particularly when the nail clippings are not clean and the oil of the dirty nails causes the clippings to adhere to the retainer and clipper, and thereby adds to the build-up of nail clippings in a next succeeding clipping operation.
Summary, Advantages and Objects of the Invention
The present invention overcomes the disadvantages heretofore present in nail clippers which are constructed to retain the clippings to the clipper during a nail clipping operation by utilizing two superimposed flat flexible spring steel elements riveted together at their distal ends, and having cooperating facing cutting edges at their proximate ends, biased apart to accommodate insertion of the nails therebetween for clipping, in which a post extends through said leaf spring elements close to the proximate ends of the spring elements and a lever reacts against the post and is fulcrumed to bring the cutting edges of the leaf spring elements together and effect a nail trimming and clippings collecting operation.
The collecting element for the nail trimmings also extends laterally of the post to opposite sides of the leaf spring elements and has deflecting faces cooperating with an arcuate recessed face of the post and relatively close to the cutting edges of the clipper to cause a continuous agitation of the clippings between the deflecting faces and post and retain the clippings in a relatively loose state even though the nails should be dirty, and to accommodate ready disposal of the clippings upon opening of the clipper with the cutting edges facing a waste basket or the like and shaking the clipper toward the cutting edges of the leaf spring elements. The post extends through the leaf spring elements and is notched at its inner end portion to form a reaction member for an actuating lever. Decelerating faces cooperate with the post to confine the clippings to the region of the cutting edges of the clipper, and cause a circulation between the deflecting faces and cutting edges of the clipper. This also alerts the user to the accumulation of clippings, for disposal.
An advantage of the present invention is in the simplicity and efficiency of the cuttings decelerating and collecting element and the low cost of manufacture thereof.
A further advantage of the present invention is that the clippings are confined and circulated in a region close to the cutting edges of the clipper so a person clipping the nails may readily be aware of the clippings accumulated and dispose of the clippings prior to an excess accumulation thereof, and thereby increase the sanitary features of the nail clipper and prevent accidental discharge of the clippings to the floor.
Another advantage of the invention is in the simplicity of the clippings collector cooperating with the reaction post of the clipper and assuring the absence of scattering of the clippings beyond the sides of the clipper and thereby increasing the sanitary features of the clipper and efficiency in operation thereof.
A principal object of the invention, therefore, is to provide a simple improvement in nail clippers which confine the clippings to the region between the cutting elements and reaction post of the clipper for ready disposal, by separating the cutting edges of the clipper and shaking to one side or the other and toward the separated cutting edges of the clipper with the cutting edges facing downwardly.
A further object of the invention is to provide a simplified and improved form of clipper for the nails of the fingers or toes having deflecting and circulating faces cooperating with a recessed face on the post and forming a continuous face across the clipper and preventing an excess accumulation of clippings by alerting the person performing the clipping operation to any excess of clippings in the nail clipper.
The foregoing objects and advantages are obtained because the clippings are concentrated at the front of the clipper and the reaction post cooperates with the transversely extending deflecting and circulating faces to form a continuous channel at the front portion of said post and to thereby allow the clippings to be freely shaked out of the clipper.
These and other objects and advantages of the invention will appear from time to time as the following specification proceeds and with reference to the accompanying drawings wherein:

Description of the Preferred Embodiment of the Invention
In the embodiment of the invention illustrated in FIGS. 1 and 2 of the drawings, I have shown a nail clipper 11 of a conventional form having a lower spring steel element 12 and an upper spring steel element 13 extending along the lower spring steel element 12. The spring steel elements 12 and 13 overlie one another and have distal ends riveted together by a rivet 15 extending through both of said elements, adjacent the distal ends thereof. The rivet 15 may form a mounting for a nail file 16 extending along the upper spring steel element, for use in filing the nails after a clipping operation thereof. The rivet 15 extends through the nail file and mounts the nail file to be pivotally moved about the axis of the rivet to extend to one side of the clipper, or along the upper spring steel element 13, and is retained thereto as by a washer 17 extending about the rivet 15 and suitably secured to said rivet in a manner known to the art so not herein shown or described further.
The spring steel elements 12 and 13 are normally biased away from each other at their proximate ends and may be held in their open position by the pressure of the washer 17 thereon. The lower spring steel element 12 has an upturned cutting edge 18 extending across said spring steel element 12 in an arcuate path and conforming to the correct contour of the clipped nail of the finger or toe.
The upper leaf spring element 13 has a corresponding cutting edge 19 conforming to and extending towards the cutting edge 18 and mating therewith during a nail trimming operation.
The leaf spring elements 12 and 13 are flexed to move together and effect a nail clipping operation by operation of an actuating lever 24 having a bifurcated end 25 extending within a downwardly facing notch 26 in a reaction pin 27. The reaction pin 27 has a head 28 engaging beneath the leaf spring element 12, and extends above the leaf spring element 13 through a slot 29 therein.
The actuating lever 24 has a heel 30 engaging the top surface of the leaf spring element 13, and reacts against the downwardly facing concave recessed portion of the reaction pin 27, and moves the two leaf spring elements 12 and 13 together to effect a clipping operation upon movement of the lever 24 in a direction, which in FIG. 1 is shown as being a clockwise direction.
Thus far the construction described is of a conventional form, similar to that shown in U.S. Pat. No. 4,380,120, so not described in further detail.
The actuating lever 24, like the actuating lever of the Hannon U.S. Pat. No. 4,380,120 can be placed in a stored condition along the top of the leaf spring element 12, between lugs 31 extending upwardly of opposite sides of the washer 17, by turning said actuating lever 24 and reaction pin 27 180.degree. from the position shown in FIG. 1 over the nail file 16, and between the retainer lugs 31, as is conventional.
Referring now in particular to the decelerating and retaining means for the nail clippings shown in FIGS. 1, 2 and 3, a clippings decelerator and accumulator 33 extends transversely of the reaction pin 27, between the leaf spring elements 12 and 13, but beneath the bottom of the leaf spring element 13 a distance sufficient to allow said leaf spring element to effect a clipping operation in cooperation with the leaf spring element 12. The decelerator and accumulator 33 is shown in FIGS. 1, 2 and 3 as a solid member which may be molded from metal or plastic and has a depending key 35 fitting in a slot 36 in the leaf spring element 12. Said decelerator and accumulator also has decelerating faces 37 extending laterally from opposite sides of a recessed face 39 of the pin 27, and with said recessed face forms a channel like deceleration face extending across and between the leaf spring elements 12 and 13, and retaining the nail clippings to circulate and decelerate between the mating cutting edges 18 and 19 while confining the nail trimmings or clippings to the faces 37 of said decelerator and accumulator and the recessed face 39 of the pin 27 and to provide a free channel extending across the cutting decelerator and accumulator to enable the clippings to readily be shaked out of the clipper as desired.
The decelerator and accumulator 33 also has bottom ledges 40 extending along the top of the leaf spring element 12 toward the cutting edges 18 and 19 and has stepped side walls 41, extending in advance of the bottom ledges 40 which merge into the undersides of top ledges 42. The top ledges 42 extend over the decelerating faces 37 for a short distance and terminate into the stepped side wall 41 extending along opposite sides of the decelerator and accumulator to a position adjacent the cutting edge 18, to entirely close the space between the fulcrum pin 27 in cooperation with the arcuate face thereof to form a decelerator and accumulator channel for the nail clippings against which the clippings impinge for the width of the leaf spring element 12, and are collected for disposal by opening the two leaf spring elements 12 and 13 and shaking the clippings to pass out of the clipper to waste between the cutting edges 18 and 19.
In the form of the invention illustrated in FIGS. 4, 5 and 6, the clippings decelerator and accumulator is like that shown in FIGS. 1, 2 and 3, but is formed from a flat plate 50 formed to extend about the side portions and rear portion of the reaction pin 27, and has a central open portion 55 extending partially about and towards the proximal ends of the flat spring steel elements 12 and 13. A tab 53a is bent from the longitudinal central portion of said plate to extend within the keying slot 36 of the spring steel element 12.
Decelerating faces 51 of the decelerator and accumulator may be bent upwardly from the plate 50 and may be of the same conformation as the faces 37 of the form of the invention illustrated in FIGS. 1 through 3. The faces 51 terminate at their outer sides and may be bent into side walls 52 extending along bottom plates formed from the plate 50 and therebeyond close to the cutting edges of the spring steel elements 12 and 13. The faces 51 form continuations of the recessed face 39 of the pin 27 and cooperate therewith to form a continuous channel extending across the spring steel elements 12 and 13 and project the clippings toward the cutting edges 18 and 19, and in effect cause a deceleration and circulation of clippings between the decelerating and accumulating faces 51 and the cutting edges 18 and 19 of the respective spring steel elements 12 and 13. The side walls 52 extend along opposite sides of the spring steel element 12, beneath upper ledges 53 and cooperate with the faces 51 and top ledges 53 extending from the tops of said side walls for a portion of the length thereof, and form channels on opposite sides of the reactor pin 27 to provide a continuous channel extending across the clippings decelerator and completed intermediate its ends by the arcuate face 39 of the reaction pin 27.
As shown in FIGS. 4 and 5, the plate 50 has a slot 55 punched from the center thereof to receive a pin or lug serving as a key to retain the decelerator and accumulator in the same general position as the decelerator and accumulator 33 shown in FIGS. 1 and 2.
The foregoing describes a simple decelerator and accumulator which may be stamped or otherwise formed from a single piece of sheet metal with a minimum of bending operations and may be welded or otherwise secured to the top face of the spring steel element 12 and which may accumulate the clippings in the region of the cutting edges 18 and 19 of the leaf spring elements 12 and 13 of the clipper.
It may be seen from the foregoing that I have devised a simplified form of decelerator and accumulator for the nail clippings of a nail clipper cooperating with a decelerating face 39 of the fulcrum pin 27 and preventing the flying of the clippings into the face or to the ground outside of the clipper in a simpler and more effective manner than the present-day nail clippers now on the market, and simplifying the construction of the decelerator and accumulator to the extent that it may be manufactured as an integral part of a nail clipper with a minimum amount of operations and at a lower cost than the nail clippers now on the market and having provisions for preventing the scattering of the nail clippings.
It further may be seen that a channel opening towards the cutting edges extends across the flexible steel elements 12 and 13 and is completed by the recessed face of the pin 27 to prevent flying of the clippings to one side or the other of the clipper, and retain the clippings between the cutting edges of the clipper and said channel, and prevent accidental discharge thereof to one side or the other of the clipper.
While I have herein shown and described one form in which my invention may be embodied, it should be understood that there may be numerous variations and modifications thereof without departing from the spirit and scope of the novel concepts of the invention.
