Description
Technical Field
This invention relates to a covers for handles and more particularly to slip resistant, elastomeric covers constructed to be applied by the user and readily removable for cleaning or replacement, especially suitable for use on meat-cutting knives.
Background Art
It is often desirable to apply a cushion-like covering to an otherwise rigid handle of an implement for improved comfort and grip. However, constructions and materials used in existing grips, especially those that can be applied and replaced by the user, are not satisfactory for many applications. In the food industry, in particular, a satisfactory slip-resistant replaceable handle cushion is needed.
Health standards in the food industry, especially the meat butchering and cutting industry, dictate a high degree of cleanliness and cleanability for equipment, including knives and other cutting tools, both hand operated and power driven. As a result, the materials used to fabricate the tools are typically non-porous, such as stainless steel, aluminum, or plastic, to minimize the foci where soil can accumulate. Power-driven hand knives, for example, typically have smooth metal or plastic handles with, perhaps, a small knurled portion to facilitate gripping by the user. The fluids and fats which result from cutting meat or other comestibles lead to slipperiness between the meat-cutter's hand or glove and the cutting tool handle.
Power tools compound the problem of slippage by contributing motor vibrations, sudden torque, and mechanical shock which can jar the tool from the operator's hand. The vibration also causes fatigue and discomfort that makes gripping the tool more difficult. Typically an operator tends to grip a slippery or vibrating tool more firmly by applying more hand pressure which leads, in the short run, to operator fatigue and, in the longer run, to occupational disabilities of the hand and forearm.
Disclosure of the Invention
The invention is a cutting tool handle cover that improves an operator's grip on the tool, provides cushioning on the handle against shock, and is washable on the handle; yet also is inexpensive and easy to install and remove so it facilitates replacement when worn or permanently soiled. More particularly, the invention provides for an elastomeric covering for a handle constructed to be applied by the user and readily removable for cleaning and replacement. The covering is characterized by a non-slip surface to facilitate hand gripping under moist or oleaginous conditions; resilience sufficient to provide cushion against mechanical shock being transmitted from the handle to the hand during use; reversible adherence to the handle to provide for non-twisting of the cover during use of the handle and further to provide for removal or replacement of the cover after use; elasticity sufficient to provide for dimensional modification of the cover so that it contacts substantially the entire surface of the handle; non-permeability to prevent fluid substances from passing through the cover to the handle; and low thermal conductivity to provide insulation against heat being conducted from the hand to the handle during use.
In one embodiment, the covering is in the form of a thin ribbed sheath; the sheath is applied to the handle by the user by unrolling a rolled-up sheath onto the handle; a fixture to aid in rolling, unrolling and exactly positioning the sheath on the handle is provided. The sheath may be cylindrical, conical or hourglass shaped, depending upon the elasticity and the configuration of the handle to which it is applied.
As used in the specification and the claims, "non-absorbing" means substantially resisting the absorbance of physiological fluids, such as blood and sera, as well as oils and fats; "washable" means amenable to the removal of physiological fluids, oils and fats, and imbedded fleshy or fatty particulates, which may be flushed out and carried away by the application of high pressure water, with or without detergent. "Closed-cell foam" refers to a cellular plastic having non-interconnecting cells open only on end surfaces. "Random and open-cell foam" refers to a cellular plastic having interconnecting cells randomly arranged.
The thin, ribbed sheath is formed by dipping a grooved sheath-form-matrix into liquidified elastomeric material, such as latex. Once the elastomeric material has set, it is stripped off the matrix and turned inside out to form the ribbed sheath. The ribs are, preferably, longitudinally arranged on the cylindrical sheath, have sharp edges to provide for good gripping, and are tapered at the ends so that there are no blunt corners to facilitate cleaning. In a preferred embodiment of the sheath, the ribs are rectilinear in cross-section and have a height of about 1/16 to about 3/16 of an inch. The height of the ribs determines, to an extent, the grip size, so that the larger ribs would be used by an operator with a large hand and the smaller ribs by an operator with a smaller hand. The contoured-wall, ribbed sheath is formed by being cast from a mold having longitudinal ribs. These ribs, like those on the thin, ribbed sheath, preferably have sharp edges to provide for good gripping and are tapered at the ends to facilitate cleaning. The ribs have a height of about 1/16 to 1/8 of an inch. The thickness of the contoured wall can be varied to change the grip size so that thicker walled sheaths would be used by an operator with a larger hand and thinner walled sheaths by an operator with a small hand. The thickness of the wall is preferably no less than about 1/8 of an inch at its thinnest portions to impart sufficient rigidity. The thickness of the wall is greater at the top and bottom of the sheath and greatest in the middle to define an hour-glass shape. Thus at the top and bottom, the wall should have a minimum thickness of about 1/4 of an inch and at the middle a thickness of about 3/8 of an inch or more to provide for good gripping depending on the operator's hand size.
In order for the thin, ribbed sheath to be applied to a handle, especially a metallic handle, it is necessary that the sheath be rolled up into a toroid shape and then accurately unrolled onto the handle This is so because the elastomeric nature of the sheath prevents it from being slidable over the handle. It is undesirable to fabricate the thin sheath so that it could be slipped over the handle or to lubricate the thin sheath for application because in either case, the covering would twist during use and present a safety hazard. Thus, once the sheath is on the handle, it adheres and cannot be positionally adjusted. Hence a fixture is provided to aid in application of the sheath so that the sheath is placed in the exactly desired position where it is unrolled onto the handle.
The fixture is proportioned so as to ensure exact placement of the sheath on a handle. The fixture comprises a tubular mandrel and base separable from the mandrel; the mandrel is dimensioned so that a sheath may be fairly easily slipped over it with or without lubrication; the mandrel may also have graduations at the top to aide in positioning of sheaths of different length or different thickness, e.g., a sheath thicker due to higher ribs will have a larger diameter when rolled than a thinner covering of the same length. The base is proportioned so as to accommodate an end of the handle within its circumference. In use, a sheath is slid over the tubular mandrel into a predetermined position on the mandrel, depending on the length or thickness of the sheath; the sheath is rolled from the top down into a toroid or donut shape; the toroid is then rolled onto the base. Once the rolled sheath is positioned on the base, the mandrel is removed; the handle to be covered is placed on the base; and the sheath unrolled onto the handle. Accordingly, there is provided a method of applying a thin, tubular, open-ended elastomeric handle covering of a predetermined length and/or thickness to a preselected area of a handle, the covering having a top-end and a bottom-end, the method being characterized by the steps of rolling the covering into a toroidal shape; placing the toroidally shaped covering in a first predetermined position; placing the handle in a second predetermined position; and unrolling the covering onto the handle; said first and second predetermined positions being located and arranged so that the covering is unrolled onto the preselected area of the handle. Preferably, the toroidally shaped covering is stretched radially prior to being unrolled.
The above and other features and advantages of the invention will become more apparent from the detailed description that follows.

Best Mode for Carrying Out the Invention
Referring to the drawings, the thin, ribbed sheath of the invention is shown generally at 20 in FIG. 1. The sheath is formed by dipping a grooved sheath-form-matrix into liquified elastomeric material such as Surtex Natural Rubber Latex, which is natural rubber latex, U.S.D.A. approved, and stripping the set latex sheath off the matrix inside out to yield the sheath 20. The grooves on the sheath-form-matrix are longitudinal so as to form longitudinal ribs 21 on the outside of the sheath. The grooves are rectilinear so as to yield sharp edges 21a on the ribs 21 to enhance gripping. The ends of the grooves are tapered to yield tapered rib ends as at 21b to facilitate cleaning of the sheath. The sheath has a top cuff 23 and a bottom cuff 24 to define the gripping area of the sheath.
FIG. 3 illustrates a fixture 30 used to roll the sheath of FIG. 1 in preparation for application to a handle. The fixture 30 comprises a mandrel 31 and a base 32. The mandrel is circular in cross section and has a first portion 31a that tapers slightly and uniformly, increasing its diameter, from a flat end 33 toward a second portion 31b. Portion 31b tapers and increases its diameter a greater rate toward a third portion 31c, which is cylindrical. The mandrel terminates at a wide end 34, in which a recess 35 is formed. The base 32 has a bottom flange 36 with holes 37 so that the base can be affixed to a work surface by screws or bolts. Atop the bottom flange of the base 32 there is a first columnar portion 32a and on top of it a reduced diameter second columnar portion 32b. The juncture therebetween defines a rolled-sheath-stopping shoulder 32c which prevents the sheath from rolling beyond a predetermined number of turns, as is more fully explained below. A boss 38 extends from the reduced diameter columnar portion 32b, dimensioned to be closely received in the recess 35 of the mandrel 31. The juncture between boss 38 and reduced diameter columnar portion 32b forms a shoulder 32d to engage the annular end 34 of the mandrel 31.
FIG. 6 illustrates a sheath 20 that conforms in size and shape to, and which is slipped over the portion 31a of the mandrel 31. As illustrated, the top cuff 23 of the sheath 20 is aligned flush with the end 33. Should a thicker or shorter sheath than as illustrated in FIG. 6 be used, the top cuff 23 may be aligned with, e.g., a mark 40 or a mark 42, circumferentially enscribed or otherwise applied on mandrel 31. The distance between the rolled sheath stopping shoulder 32c and the tip end 33 or, e.g., mark 40 or mark 42, is predetermined according to the length and thickness of the sheath 20 so that when a particularly sized sheath 20 is rolled down the mandrel 31 until stopped by the rolled sheath stopping shoulder 32c, the sheath 20 will have rolled a predetermined number of turns so that it is positioned accurately for unrolling onto a handle.
As illustrated diagrammatically in FIG. 7, the top cuff 23 of the sheath 20 is rolled down the fixture 30. Rolling is commenced as illustrated in position A; as rolling continues through position B, the top cuff 23 is enclosed within the rolled-up portion of the sheath; at position C, the sheath 20 is completely toroidal, with the bottom cuff 24 still against the surface of the mandrel. At that point the mandrel gradually expands in diameter. Further rolling of the sheath 20 down the mandrel 31 toward and onto the column portion 32b and against the shoulder 32c stretches the rolled sheath radially and is carried out so as to position the toroidal sheath with the bottom cuff 24 located as illustrated in position D, exactly at the top of portion 32b of the base. The radial stretching is necessary because the sheath must be in a radially stretched condition when applied to the handle to prevent subsequent slippage. When the rolled-up sheath is in position D on the base, the mandrel 31 is removed from the base and replaced by a handle, e.g., a knife handle 50, as illustrated in FIG. 8. The column portion 32b is essentially the same diameter and shape as the outside diameter of the base of the handle, and the boss 38 is constructed to fit closely within the base of the knife handle. A bottom end 51 of the knife handle rests on the shoulder 32d of the base. The bottom cuff 24, not visible in FIG. 8, is located essentially flush with the bottom 51 of the handle 50. The rolled sheath 20 is then unrolled upward so as to be placed in the exactly desired position between the bottom 51 and the top 52 of the handle 50. As previously mentioned, this arrangement is necessary because the sheath cannot be positionally adjusted once it is rolled onto the handle.
As illustrated in FIG. 8, the knife handle 50 is placed on the base 32 of the Fixture 30 so that the sheath 20 will be unrolled toward the blade end 53. This arrangement is used when the knife is of the electric motor driven type having a hollow handle 50 adapted to removably receive a drive cable. Knives of this type are shown, e.g., in U.S. Pat. No. 4,439,924. With an air motor driven knife the drive is not conveniently removable, but the blade end 53 can be made removable from the handle 50; and in that case the base 32 can be dimensioned to receive the top 52 of the handle 50. The sheath 20 is then rolled onto the handle in the direction starting at the top 52 rather than the bottom 51, as described above.
Although the sheath 20 and fixture 30 are illustrated in FIG. 8 as adapted for a somewhat tapered handle, or an hourglass shaped handle as in FIG. 8, the sheath 20 and fixture 30 can be constructed and arranged for other shapes, such as cylindrical. Where the handle is placed on the mandrel in an inverted position, the shape of the mandrel and/or the sheath may require modification, but within reasonable limits, the sheath will stretch and contract to accommodate variations.
With an appropriate hollow handle of the article to which the sheath is to be applied, the mandrel 31 need not be separable from the base 32; e.g., if the knife or other tool construction is hollow and thin walled over the length to which this cover is to be applied. In that case, the mandrel can be shaped so that when the sheath 20 is rolled to a position against the shoulder 32c, the hollow handle can be simply slipped over the mandrel 31 and stopped by a handle stopping portion on the mandrel, formed by, e.g., a increased diameter portion on the mandrel beyond which the handle will not pass, but past which the sheath can be rolled.
From the foregoing description of the preferred embodiments of the invention it will be apparent that the advantages of the invention heretofore enumerated and others have been accomplished and that there has been provided a slip-resistant, cushioning covering for a handle. While preferred embodiments of the invention have been described in considerable detail, various modifications or alterations may be made therein without departing from the spirit or scope of the invention set forth in the appended claims.
