This invention relates generally to a protective garment. More particularly, the present invention is directed to a protective garment worn by a person who requires protection from injury by cutting or slashing by broken glass or with other sharp edged articles such as blades, knives, and the like.
Glass handlers, in particular, are often exposed to potential injury and must wear suitable protective clothing. In the past, sweaters were typically knit with two panels, i.e., a front panel and a back panel. These two panels were joined together with an attached sleeve. This type of design leaves an upper shoulder and neck seam. Seams are the weakest part of a cut resistant product.
Numerous patent documents have been directed to cut resistant garments and have been various features thereof. For example, U.S. Pat. No. 7,043,766 (Foreman et al.) is directed to a garment that has indentations forming air channels next to the body of the wearer. One of the yarns is formed from a material such as Kevlar to provide cut resistance.
U.S. Pat. No. 6,044,498 (Schumann et al.) is directed to a slash and cut-resistant garment for protecting a person from injury by slashing or cutting with a blade, knife or other sharp edged device. The garment comprises a neck protector attached to a shoulder portion. The neck protector portion uses double knit fabrics or multi-layer fabrics. Foam layers or other materials are disclosed which are used to provide stiffening to keep protection in place on the neck.
U.S. Pat. No. 5,210,877 (Newman) is directed to abrasion and cut-resistant protective clothing for bicycling. The outerwear is constructed with protective fabric panels containing abrasion and cut resistant high performance fibers. The protective panels are structural components and are sewn or otherwise attached to panels or sections of conventional textiles to complete the garment.
U.S. Pat. No. 5,023,953 (Bettcher) is directed to a garment and protective sleeve. A sleeveless sweater has a detachable cut-resistant full length protective sleeve. Shoulder seams are shown in
International Patent Publication No. WO 2005/1116316, by Wells Lamont Industry Group, is directed to a protective, cut-resistant sleeve and a method of making the sleeve. The sleeve is a tubular sleeve of flexible-cut resistant material made from cut-resistant fiber using a rib type knitting stitch. The rib knit stitch allows greater flexibility in knitting.
European Patent No. EP 1 728 442, by Eckhard Hotz of Gen any, is directed to a cut protection garment for preventing injuries when using a chainsaw or saw and includes a first layer of a cut-resistant material and a second layer arranged on the first layer.

The closure includes a hook and loop fastener providing stiffness relative to the collar to support the collar.
A method for manufacturing a cut resistant garment is also provided, where the cut resistant garment includes a sweater portion having a chest portion, a first sleeve having a cuff, a second sleeve having a cuff, and a collar. The method includes the steps of providing a cut resistant yarn and knitting the cut resistant yarn into a sweater without any exposed shoulder seams. The knitting is accomplished in the order of (a) the cuff of the first sleeve, (b) the first sleeve, (c) the body, (d) the second sleeve, and (e) the cuff of the second sleeve. The order may include knitting the collar at the same time as knitting the body. Alternatively, a separately manufactured collar may be attached to the sweater after the knitting step. Preferably, the knitting steps are performed using a flatbed knitting machine.
The invention will be described in conjunction with the following drawings in which like reference numerals designate like elements and wherein:
The invention will be illustrated in more detail with reference to the following embodiments, but it should be understood that the present invention is not deemed to be limited thereto.
Referring now to the drawings, wherein like reference numbers refer to like elements throughout the several views, there is shown in
The sweater portion 12 includes a chest portion 16, a pair of sleeves 18, 20, a collar 22 and a closure 24. The collar 22 has a top edge 26 and a bottom edge 28. The bottom edge 28 of the collar 22 is integral to the top of the chest portion 16.
The closure 24 extends from the top edge 26 of the collar 22 through at least part of the chest portion 16. The closure 24 includes an opening 30 extending from the top edge 26 of the collar 22 through at least part of the chest portion 16. A hook and loop fastener 32, such as a Velcro® brand fastener, has a first part 34 and a second part 36, one of which includes hooks 38 and one of which includes loops 40, as are well known. The first part 34 is removably and reusably attachable to the second part 36.
A strip 42, preferably made from a fabric 44, has a first part 34 of the hook and loop fastener 32, for example, the hook portion, thereon. This first part 34 is not required to be a single piece of hook or loop fabric. For example, as shown in
This arrangement, advantageously, provides for a closure 24 which is ambidextrous. That is, the strip 42 can be pulled from either one of the strips adjacent to each of the first side 46 of the opening 30 and the second side 48 of the opening, while remaining secured to the other. The strip 42 can be pulled from the left side or the right side of the sweater portion 12. Preferably, the closure 24 (including the opening 30 and the hook and loop fastener 32) are stiff relative to the collar 22 to support the collar.
The cut resistant garment 10 may further include an apron 14 made from a cut resistant material 56. The apron 14 is attachable to a lower part 50 of the sweater portion 12 via a hook and loop fastener 58. Preferably, only the hook portion is present on the apron 14. The material of the apron 14 serves to function as the hook portion of the fastener. Additionally, a strip 52 of a hook type fastener fabric 54 of a hook and loop type fastener may be used that assists in attaching the apron 14 to a user. The strip 52 is attached to an upper corner 60 of the apron 14, goes around the waist of the user, and attaches back to the apron to loop material 62 on the apron 14. Loop type fastener fabric may be present on the back side of the apron to secure the strip 52 to the apron for laundering.
Preferably, the apron 14 is a knit fabric. This allows the fabric of the apron 14 to stretch ahead of a cutting edge to increase cut resistance. Previous aprons in the prior art used Kevlar brand twill or leather.
Preferably, all hook and loop fasteners discussed above utilize the loop portion of the fastener on the sweater portion 12 and the apron 14 such that the sweater portion 12 and the apron 14 can be laundered without the hook and loop fastener portions randomly attaching to one another.
Preferably yarn deniers are between about 400 and 2000. The yarn may be, but is not limited to, any combination of high pressure polyethylene (HPPE), fiberglass, polyester, polypropylene and steel, nylon, high tenacity nylon, and the like. Preferably, the knitting machine is a flatbed knitting machine.
Preferably, the apron 14 is made from a knit fabric that is cut resistant. Previous panel designs have been woven fabrics. Knit fabrics stretch in order to add cut resistance and allow individual fibers to twist and roll in the knit fabric for additional cut resistance. Woven fabrics do not offer these benefits.
Importantly, the sweater portion 12 of the cut resistant garment 10 is preferably knit by providing a cut resistant yarn and knitting the yarn into a sweater without any exposed shoulder seams. This is accomplished by knitting in the following unique order. First, the cuff of the first sleeve is knit. Second, the first sleeve is knit. Third, the body is knit. Fourth, the second sleeve is knit. Finally, the cuff of the second sleeve is knit. A step of knitting the collar may occur during the step of knitting the body. Alternatively, a step of attaching the collar, subsequent to the step of knitting the cut resistant yarn into a sweater, may be included. Knit in this manner, the sweater provides safety and strength in the shoulder area because no exposed shoulder seams are present. Moreover, unlike cut resistant garments in the past which utilized two panel construction (front and back), joined with an attached sleeve, the present cut resistant garment drapes properly due to its ability to utilize a tapered design in the armpit area and the unique construction process described here.
The present invention, as shown in the figures, utilizes a closure 24 located on the back side of the sweater portion 12. Use of such a rear closure 24 provides full frontal protection from cuts.
While the invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope thereof.
