Description
Chempact Glove and Method of Manufacturing Same FIELD OF THE INVENTION
This invention relates to protective hand devices. More specifically, but without limitation, this invention relates to gloves that protect hands from exposure to hazardous substances and crushing impacts.
Gloves are generally a fitted covering for the hand, usually made of leather, wool, cloth, or rubber. Gloves have a separate sheath for each finger and the thumb.
As those of ordinary skill in the art will recognize, hand injuries from exposure to hazardous substances and crushing impacts occurring in work and recreational environments can be painful and debilitating.
Prior art gloves include various cover arrangements that act to protect the hand from injury. U.S. Pat. No. 5,459,880 issued to Sakaki et al. discloses a glove that has a laminated part in which a plurality of different types of rubbers are successively laminated, and where the lowermost layer is a natural rubber layer, and the top surface layer is an oil-resistant rubber layer.
U.S. Pat. No. 5,499,400 issued to Masuda et al. discloses a knitted work glove having coated with vinyl chloride resin paste or natural rubber. The glove has improved flexibility because of the restriction of the degree of infiltration of the coating, so as to produce a thin coating when the outer surface of a knit glove is covered with the coating.
U.S. Pat. No. 6,566,435 issued to Teoh et al. discloses an elastomeric carboxylated nitrile rubber glove made from prevulcanized carboxylated nitrile rubber latex with 2 to 6% by weight methacrylic acid equivalent.
U.S. Pat. No. 6,673,404 issued to Yeh et al. discloses a glove having an inner coating of a nitrile rubber with an intermediate layer of a rubber blend comprised of natural or synthetic rubber and nitrile rubber interposed between the nitrile coating and the base glove.
U.S. Pat. No. 6,874,165 issued to Lee discloses a glove formed by a formulation of nitrile butadiene rubber latex material, with a thickening agent of carboxymethyl cellulose in latex material for making a NBR glove.
U.S. Pat. No. 6,993,793 issued to Li discloses a grasping-enhanced industrial glove comprising an inner cotton layer having a finger portion; a sheet of net layer being seamed to the finger portion; the net layer being adhered with thick rubber material by placing the inner cotton layer in a hand mold and soaking in a rubber material; the rubber material of the net layer having a width of about 20% to 30% of the net layer; and an outer rubber layer having a texture portion.
U.S. Pat. No. 7,100,212 issued to Jaeger discloses a fitted glove structure that incorporates a molded rubber palm piece that has a portion which extends over certain of the glove fingertips to the back piece in a manner to increase wearer comfort and protection and to enhance the object pick up capabilities of the glove.
U.S. Pat. No. 7,310,826 issued to Kishihara discloses a work glove having a base material made of fiber and a foam layer composed of a thermoplastic resin or a rubber provided thereon, the foam layer having irregularities formed by heat press on the surface is provided, where the foam layer has both film strength and abrasion resistance without deterioration in the non-slip properties usually possessed by the foam layer.
As discussed above, numerous prior art gloves have been developed. However, all of the prior art gloves suffer from the inability to adequately protect the user from hand injury arising from exposure to hazardous substances and crushing impacts.
Hence, an object of the present invention is to provide a protective hand device, and a method for manufacturing same, for protecting the hand from exposure to hazardous substances and crushing impacts.
SUMMARY OF THE INVENTION
One embodiment of the present invention is a glove that is manufactured by dipping a knitted glove up to the wrist band in coating material and attaching impact pads to the back side of each of the four finger compartments and the thumb compartment.
Another embodiment of the present invention is a glove that is manufactured by dipping a knitted glove up to the wrist band in a first coating material, attaching impact pads to the back side of each of the four finger compartments and the thumb compartment, and flat-dipping the palm-side of the glove into a second coating material.
Another embodiment of the present invention is a glove that is manufactured by attaching impact pads to the back side of each of the four finger compartments and the thumb compartment of a knitted glove and flat-dipping the palm-side of the glove into a coating material.
In all three embodiments, the impact pads attached to the back side of each of the four finger compartments and the thumb compartment extend from the end of the finger and thumb compartments to the back side of the palm area. The impact pads include a first density section joined to a second density section, and include a plurality of lateral slices configured to allow flexion and extension of the hand.
DESCRIPTION OF THE INVENTION
While the present invention will be described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the present invention not be limited to the particular embodiments disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments (and legal equivalents thereof) falling within the scope of the appended claims.
As shown in FIGS. 1 through 7, the present invention is a protective glove 10, having a hand enclosure 11 with separate compartments 12 for all four fingers, another separate compartment 13 for the thumb, and a wrist band 14 for keeping foreign material from entering the interior of protective glove 10. Protective glove 10 of the present invention is preferably, but not necessarily, manufactured from a stretch knit fabric, such as is commercially available from Top Value Fabric Inc. under the name Cotton/Lycra Knit.
In one embodiment of the present invention, protective glove 10 is coated with a first coating material 15 to provide protection to the hand inside protective glove 10 from exposure to hazardous substances and conditions. One method of applying first coating material 15 includes dipping protective glove 10 into first coating material 15 to cover every part of protective glove 10 except wrist band 14. First coating material preferably has good flexibility, even in extreme temperatures, high abrasion resistance in severe conditions, good high-temperature, oil, and chemical resistance, and good mechanical properties, including strength, elongation, and tear resistance.
Once protective glove 10 is coated with first coating material 15, impact pads can be attached to the back side of hand enclosure 11, finger compartments 12, and thumb compartment 13. Impact pads 16 can be attached to the back side of hand enclosure 11, finger compartments 12, and thumb compartment 13 by any means known to those skilled in the art, but the preferred method of attachment is using a glue product known as Henkel Loctite 308.
Impact pads 16 preferably have dual layers, i.e., a first (top) density layer 17 and a second (bottom) density layer 18. In addition, impact pads 16 preferably have slices 19 formed therein, where slices 19 preferably extend through first (top) density layer 17 and into second (bottom) density layer 18. Slices 19 are preferably configured to allow full flexion and extension of the hand, fingers, and thumb inside protective glove 10.
Second (bottom) density layer 18 is closet to the hand inside protective glove and, therefore, is preferably thicker and softer than first (top) density layer 17 for comfort purposes. First (top) density layer 17 is preferably thinner and harder than second (bottom) density layer 18 as it functions to disperse the energy of a crushing impact across a larger square inch area of the underlying second (bottom) density layer 18.
The use of a double-density impact pad is more efficient and makes protection of the hand inside protective glove 10 possible, while not sacrificing dexterity.
In the preferred embodiment, impact pads 16 are constructed of ethylene vinyl acetate (EVA). In the preferred embodiment, first (top) density layer 17 on finger impact pads 16 has a thickness of approximately 0.156 inches and a hardness durometer value in the general range of 75-80. Second (bottom) density layer 18 of finger impact pads 16 preferably has a thickness of approximately 0.500 inches and a hardness durometer value in the general range of 50-55. First (top) density layer 17 for thumb impact pad 16 preferably has a thickness of approximately 0.12 inches and a hardness durometer value in the general range of 75-80. Second (bottom) density layer 18 for thumb impact pad 16 preferably has a thickness of approximately 0.36 inches and a hardness durometer value in the general range of 50-55.
In a second embodiment, protective glove 10 of the present invention is coated with a first coating material 15 (as discussed above), after which impact pads 16 are attached to the back side of finger compartments 12 and thumb compartment 13 (as discussed above), but then protective glove 10 is dipped in a second coating material 20 by flat dipping protective glove 10 (palm side down) in second coating material 20 so as to cover the palm area and the palm sides of finger compartments 12 and thumb compartment 13. Like first coating material 15, second coating material 20 preferably has good flexibility, even in extreme temperatures, high abrasion resistance in severe conditions, good high-temperature, oil, and chemical resistance, and good mechanical properties, including strength, elongation, and tear resistance.
In a third embodiment of the present invention, protective glove 10 is equipped with an inner liner (not shown) having a fleece-type layer facing the back of the hand and a vinyl-type layer attached to protective glove 10. The fleece-type layer provides comfort to the hand inside protective glove 10, while the vinyl-type layer provides a surface upon which impact pads 16 can be attached, preferably by gluing. Similar to the embodiments discussed above, in the third embodiment, impact pads 16 are attached to the back side of finger compartments 12 and thumb compartment 13. Then protective glove 10 is dipped in a second coating material 20 by flat dipping protective glove 10 (palm side down) in second coating material 20 so as to cover the palm area and the palm sides of finger compartments 12 and thumb compartment 13. Like the coating materials discussed above, the coating material used in the third embodiment of the present invention preferably has good flexibility, even in extreme temperatures, high abrasion resistance in severe conditions, good high-temperature, oil, and chemical resistance, and good mechanical properties, including strength, elongation, and tear resistance.
Although the present invention has been described in terms of certain preferred embodiments, it will become apparent that modifications and improvements can be made to the inventive concepts herein without departing from the scope of the invention. The embodiments shown herein are merely illustrative of the inventive concepts and should not be interpreted as limiting the scope of the invention.
