METHOD AND APPARATUS FOR PROTECTING A HAND FROM REPEATED ABRASION
Method and apparatus for covering a hand in a manner that provides a high level of protection against abrasion as a side area of a palm is dragged across a physical component. This is accomplished by moving the seam used to attach a top and bottom component of a hand away from the side region of the palm toward the top of the hand. In this way, the seam remains undisturbed as the palm is dragged across a work product.
The art of manufacturing gloves is not overly sophisticated and most of what is known in the field has been known for decades, if not centuries. Gloves have been made and used since at least as early as the Egyptian dynasty of Tutankhamen. In fact, a pair of linen gloves was discovered in Egypt in the tomb of King Tutankhamen dating some 1,400 years BC. And, in all this time, the art of making gloves has advanced little.
The fact that it is so simple to make a glove has really retarded the development of new features. A glove is a glove and in such a narrow field of art, it is easy to appreciate that there are two major components to a glove and not much more. The first component includes a posterior portion, which is used to substantially cover the top portion of a hand. The second component, as one might easily guess, is the anterior portion that covers most of the bottom of the hand. Some portion, typically a region proximate to a boundary line where the anterior and posterior portions are sewn together.
Some of the newer features in glove making include concepts such as providing for additional material at areas where high wear is anticipated. One such example is found in a welder's glove. A welder, for example, will steady the hand on a corner surface proximate to a weld line. The welder most often does this by setting a portion of a side of the palm, opposite the thumb, on such a corner. As the weld is accomplished, the welder will slide his hand along the corner. As such, the glove will experience great abrasion on the side of the palm. In all known glove designs, a stitched seam, which is typically right at the middle of the side of the palm, will be subject to this abrasion. Once the stitching fails, the glove will typically fall apart. As a consequence, this type of wear results in a much shorter service life for the glove. This may be good for the glove manufacturer, but it certainly is annoying to discard an otherwise perfectly good glove just because of a failure of the interface stitching resulting from a typical usage scenario.
Some glove manufacturers have hoped to reduce this type of failure by adding additional material to the side of the palm of the glove. This is typically accomplished by placing a patch over the stitching so that abrasive wear can be restricted. However, once the patch is worm through, it makes for a fabulous guide that directs subsequent abrasion the stitching. Failure of the stitched interface between the top and bottom components of the glove is simply inevitable.
Several alternative embodiments will hereinafter be described in conjunction with the appended drawings and figures, wherein like numerals denote like elements, and in which:
For the purposes of this disclosure, another region of interest is the metacarpal region 110 of each digit. The metacarpal region is situated immediately outward from the wrist 115. There are bones included in the wrist that are also of interest as reference points including the triquetral bone 120. Also, the position of the fourth digit 125 and fifth digit 130 are also good references to note as the alternative methods and embodiments disclosed herein are fully described. Each digit includes a metacarpal region that is referred to by the digit, e.g. a second metacarpal region is the metacarpal region of the second digit.
According to this alternative example method, a second component is then used to cover a bottom portion of a hand, including substantially all of the palm (step 35). This second component is also used to cover a substantial portion of the side of the palm (step 40) and the top of the hand in a region that is defined as a substantial portion of the fifth metacarpal region (step 45).
In order to create a complete covering for the hand, the second component is attached to the first component beginning on top of the hand at a point that substantially overlays a triquetral bone 120 in the hand (step 50). In this example method, attachment of the first and second components continues along a path on top of the hand that traverses across the fifth metacarpal region (step 55) and then proceeds along a boundary region lying between the fifth and fourth metacarpal regions (step 60).
This alternative method further includes a step for cinching the material in the second component, which is used to cover a substantial portion of the bottom of the hand, at a point proximately overlaying the triquetral bone 120 and continuing around the wrist until it meets an interface between the first and second components (step 75). It should be appreciated that cinching the material, at least according to one alternative example methods comprises applying a gathering material and stitching the gathering material one of the components (i.e. at least one of the first component and the second component) while the gathering material is in an expanded state.
Hence, so long a stitching along the side of the palm is avoided, at least one of the first component and the second component include one or more elements (i.e. subcomponents). Accordingly, the claims appended hereto are not intended to be limited to embodiments that include only two contiguous components. As such, embodiments that include two components where one or more of these components includes subcomponents are to be considered within the scope of the claims hereto attached.
As depicted in
It is appropriate to notice the included seam line 180 on the top of the hand that is used to attach the first and second components along a path that begins at a point on the top of the hand that proximately overlays at least one of the triquetral bone 120 and the pisiform bone 122 and continues to traverse the fifth metacarpal region and continues along an interface between the fifth and fourth metacarpal regions. This path is but one example embodiment that allows the side of the palm to be substantially devoid of a seam line.
In yet another alternative example embodiment, the first gathering stich 152 begins on the top of the hand at a point that proximately overlays an interface between the hamate bone 121 and the fourth metacarpal bone. This first gathering stich 152 continues across the first component 150, substantially orthogonal to the radius bone 193, until it meets the second component 160. The second gathering stich 162 also begins on the top of the hand at a point proximately overlaying the triquetral bone 120 and continues around the wrist to the bottom of the hand and traverses the second component so as to be substantially orthogonal to the radius bone 193 and continues until it meets the first component 150.
While the present method and apparatus has been described in terms of several alternative and exemplary embodiments, it is contemplated that alternatives, modifications, permutations, and equivalents thereof will become apparent to those skilled in the art upon a reading of the specification and study of the drawings. It is therefore intended that the true spirit and scope of the claims appended hereto include all such alternatives, modifications, permutations, and equivalents.
