DETAILED DESCRIPTION OF THE INVENTION
[0046]
Glove Regions
[0047] The glove 100 generally includes a main body region 102 and finger regions 104. The main body region 102 extends from a proximal end of the finger regions 104 to an opening defined by a cuff 106. Thus, the illustrated glove 100 includes the main body region 102, the finger regions 104 and the cuff 106. Other configurations are possible.
[0048] With reference to
[0049] In some configurations, and as shown in
[0050] The main body region 102 generally is formed by stitching or otherwise joining the palm panel 110 and the dorsal panel 112. The dorsal thumb panel 114 may be stitched or otherwise joined to a thumb portion of the palm panel 110 at a first join and to the side edge of the dorsal panel 112 at a second join. Thus, in the illustrated configuration, the cuff 106 is defined by the bottom edge of the dorsal panel 112, the bottom edge of the palm panel 110, and the bottom edge of the dorsal thumb panel 114. The cuff 106 may include edge binding or the like. The edge binding may reduce the likelihood of fraying or tearing while reinforcing the material in the region of the cuff 106.
Cuff Design
[0051] The glove may be provided with any suitable cuff construction. In some configurations, the glove includes an open-cuff configuration (see, e.g.,
Finger Guards
[0052] With reference to
[0053] In the configuration illustrated in
[0054] A distal end 124 of one or more of the finger guards 122 may be rounded, as shown in
[0055] The finger guards 124 may be provided with flexure zones 126. As shown in
[0056] The finger guards 124 may be formed of a thermoplastic rubber (TPR). In some configurations, the TPR may have a Shore hardness of between Shore A 10 and Shore A 60. In some configurations, the TPR may have a Shore hardness of Shore A 35 and to Shore A 45. Other materials are possible; however, using TPR with a suitably soft durometer has been found to provide advantageous properties. In particular, soft durometer Shore A materials are known to have a Shore A hardness of between 10 and 35 while medium soft durometer Shore A materials are known to have a Shore A hardness of between 35 and 60. Thus, the finger guards 124 may be soft or medium soft durometer materials.
[0057] With reference to
Knuckle Guards
[0058] With continued reference to
[0059] Each of the index finger portion 134 and the extended portion 136 may include a respective flexure zone 142, 144. Similar to the flexure zones 126 described above, one or both of the flexure zones 142, 144 may be defined by one or more gaps 146, 148, respectively, formed through at least a portion of the thickness of the two portions 134, 136. In some configurations, four gaps 146, 148 may be provided in one or both of the flexure zone 142, 144. As shown in
[0060] With reference still to
[0061] The knuckle guard 132 may be formed of a thermoplastic rubber (TPR) that is either a soft durometer or medium soft durometer material. In particular, soft durometer Shore A materials are known to have a Shore A hardness of between 10 and 35 while medium soft durometer Shore A materials are known to have a Shore A hardness of between 35 and 60. Thus, the finger guards 124 may be soft or medium soft durometer materials. Other materials are possible; however, using TPR with a suitably soft durometer (e.g., soft or medium soft durometer) has been found to provide advantageous properties. In some configurations, the knuckle guard 132 and at least one of the finger guards 122 are formed in an integrated, monolithic single piece construction. In some configurations, the knuckle guard 132 and at least one of the finger guards 122 are formed as completely separate components (see
[0062] To improve access to tight and confined spaces, the knuckle guard 132 tapers from a region of greatest thickness toward the fingers. A maximum height of the knuckle guard 132 may be between 7.5 mm and 5.5 mm. In some configurations, the maximum height of the knuckle guard 132 is 6.5 mm. In configurations where the knuckle guards 132 and the finger guards 122 are integrated into a single construction, the tapering extends from the knuckle guard 132 to the fingertips 124, where the maximum height is between 3 mm and 5 mm. In some configurations, the maximum height at the distal end 124 of the fingers is 4 mm.
Dorsal Layering for Attenuation
[0063] As discussed above, there is a desire to provide a glove configuration that results in a Level 1 PASS rating of impact attenuation under EN 13594: 2015 and/or meets the standards of ANSI/ISEA 138-2019. To provide adequate impact attenuation in a cost effective manner, the gloves 100 employ layering across an impact zone on the dorsal side (i.e., the back-of-the-hand side) of the gloves. The layering of the materials that define the protection region on the back of the hand may provide a low profile construction for the impact attenuating region. The layering further may provide a cost-effective construction for the impact attenuating region. The layering also may provide a simplified assembly process for the impact attenuating region. In some configurations, the layering may achieve all three of these goals. In some configurations, and as used herein unless understood differently from the context of its usage, the impact attenuating region is the region of the glove that correlates to the back of the wearer's hand in the first knuckle/distal portion of metacarpal region of the wearer's hand such that the impact attenuating region may protect the first knuckles and portions of the metacarpals that are adjacent to the first knuckles.
[0064] The knuckle guard 132 described directly above is on the outside of the glove 100. While a knuckle guard or other protective element may be thickened to achieve a satisfactory level of impact attenuation without layering of materials, a thickened knuckle guard or other protective element may reduce the ability of the wearer to use the glove in confined spaces; the use of layering as described herein achieves a similarly satisfactory level of impact attenuation with a lower profile and a lower cost of manufacture than simply providing a thicker knuckle guard or other protective element. In some configurations, the layering that will be described achieves a Level 1 PASS rating when the EN 13594: 2015 standard testing is employed, and also meets the standards set forth in ANSI/ISEA 138-2019.
[0065] With reference now to
[0066] The knuckle guard 132 and/or the finger guards 122, as discussed above, may include a low durometer thermoplastic rubber material. In some configurations, the knuckle guard 132 and the finger guards 122 are formed of a single piece construction such that manufacture of the glove 100 may be simplified. In such configurations, at least one of the finger guards 122 and the knuckle guard 132 may be integrated into a single piece to simplify manufacture of the glove 100. In some such configurations, three of the finger guards 122 and the knuckle guard 132 may be integrated into a single piece to simplify manufacture of the glove 100.
[0067] In some configurations, the knuckle guard 132 and/or the finger guards 122 include a flange 162 that surrounds a main body of the knuckle guard 132 and/or the finger guards 122. The flange 162 and the main body of the knuckle guard 132 and/or finger guards 122 may be formed in a monolithic, single piece construction (e.g., molded as a single piece). The knuckle guard 132 and/or finger guards 122 may be secured to the first outer layer 160 in any suitable manner. The flange 162 may be used to secure the knuckle guard 132 and/or finger guards 122 to the first outer layer 160. In some configurations, the flange 162 may be secured to the first outer layer 160 using high-frequency radio waves. The flange 162 has been found to increase the longevity of the connection between the knuckle guard 132 and/or finger guards 122 and the underlying materials of the glove 100. The illustrated flange 162 includes cut-outs 164 or less material in the regions that overlap the bend points of the glove 100 (e.g., the regions of the glove 100 that correspond to the knuckles of the wearer). The cut-outs 164 may improve flexure of the knuckle guard 132 and/or the finger guards 122.
[0068] A sponge layer 170 includes an open cell foam. The sponge layer 170 provides the outer material 160 with a bit of volume. In some configurations, the sponge layer 170 has a thickness of between 2 mm and 4 mm. In some configurations, the sponge layer 170 has a thickness of 3 mm. In some configurations, the sponge layer 170 extends beyond the outer perimeter of the knuckle guard 132 and/or finger guards 122. In some configurations, the sponge layer 170 is coextensive with the first outer layer 160.
[0069] The sponge layer 170 is disposed beneath the first outer layer 160. In some configurations, the first outer layer 160 and the sponge layer 170 may be combined to define at least a portion of a laminate. The laminate may define the outer material in such configurations. In some configurations, the sponge layer 170 is in direct contact the first outer layer 160, which first outer layer 160 is secured to the knuckle guard 132 and/or finger guards 122. In some configurations, the first outer layer 160 is positioned between the sponge layer 170 and the knuckle guard 132 and/or finger guards 122. In some configurations, the first outer layer 160 is made of a fabric or leather material and the fabric or leather material is positioned between an open cell foam sponge layer 170 and a soft or medium soft durometer thermoplastic rubber knuckle guard 132 and/or one or more soft or medium soft durometer thermoplastic rubber finger guards 122.
[0070] A second layer 172 may underlie the sponge layer 170. In some configurations, the second layer 172 is a second fabric layer. In some such configurations, the second fabric layer 172 is a tricot material. The sponge layer 170 may be positioned between the first fabric layer 160 and the second fabric layer 172. In some configurations, the first outer layer 160, the sponge layer 170, and the second layer 172 are combined to define a composite material, such as a laminate material. In some such configurations, the sponge layer 170 may be in direct contact with the first outer layer 160 and the second layer 172. In some configurations, the sponge layer 170 is positioned below the outer layer 160, which outer layer 160 is made of a mesh material, and above the second layer 172, which second layer 172 is made of tricot. In some other configurations, there is no second layer 172 and at least a portion of the sponge layer 170 is in direct contact with a foam layer 174.
[0071] The foam layer 174 may be disposed between hand of the user and the knuckle guard 132 and/or the finger guards 122. The foam layer 174 may be formed by any material having the desired impact attenuation properties. In some configurations, the foam layer 174 includes an EVA foam. In some configurations, the foam layer 174 is made of an EVA foam. The foam layer 174 may have any desired thickness. In some configurations, the foam layer 174 has a thickness between 2 mm and 4 mm. In some configurations, the foam layer 174 has a thickness of 3 mm. In some configurations, the foam layer 174 is between 2 mm and 4 mm and the foam layer 174 is made of an EVA foam material. In some such configurations, the foam layer 174 has a thickness of 3 mm and the foam layer 174 is made of an EVA foam material. In some configurations, the foam layer 174 is positioned below the second layer 172. In some such configurations, the foam layer 174 abuts the second layer 172. In some such configurations, the foam layer 174 is glued or otherwise adhered or cohered to the second layer 172. In some such configurations, the second layer 172 is made of tricot.
[0072] The foam layer 174 underlies the knuckle guard 132. In some configurations, the form layer 174 does not underlie the majority of the surface area of the finger guards 122. The foam layer 174 preferably extends only in the area underneath the knuckle guard 132. In some configurations, however, the foam layer extends 1-5 mm beyond the periphery of the knuckle guard 132. With reference to
[0073] An inner layer 180 may underlie the foam layer 174. The inner layer 180 may be a fabric layer. The inner layer 180 may be structured to abut the hand of the wearer. In some configurations, the inner layer 180 may be made of tricot or another suitable material. In some configurations, the inner layer 180 is a nylex fabric material. The inner layer 180 may be used in combination with one or more of the other layers to lock the foam layer 174 in position. For example, by adhering, cohering, or otherwise securing the inner layer 180 to the second layer 172, the foam pad may be locked in position along the layers 172, 180 and may be enveloped by the layers 172, 180.
[0074] Advantageously, the foam layer 174 and the knuckle guard 132 may be combined to create a compact layered impact attenuation construction that may be formed in a simple, cost-effective manner. The foam layer 174 and the knuckle guard 132 should have thicknesses such that the glove 100 featuring the foam layer 174 and the knuckle guard 132 aligned as described herein will meet the minimum level of impact attenuation required to allow the glove 100 to achieve a Level 1 PASS rating when the EN 13594: 2015 standard testing is employed, as well meet the standard set forth in ANSI/ISEA 138-2019.
