Abstract
An impact resistant article includes a base portion with an impact pad attached to the base portion. The impact pad includes a padding material and a fabric laminated to the padding material. The padding material features fold lines generally corresponding to a wearer's natural bending locations when the impact pad is secured to the base portion.
Description
CA Application Bikes Ref: 10703100001
2 FIELD OF THE INVENTION
3 [0001] The present invention relates generally to protective gloves, sleeves and clothing and, in
4 particular, to a pad and an article resistant to impact forces.
BACKGROUND
6 [0002] In a number of industries, such as the oil and mining industry, hands are subjected to 7 heavy lifting and moving. As a result, hands are often in motion with heavy parts, tools and 8 equipment, which causes mechanical impact hazards for workers' hands.
Injuries in these 9 types of environments may be due to such mechanical impact hazards.
[0003] The glove of choice by many workers in industries such as the oil and mining industry 11 are ordinary "chore gloves," an example of which is the Super Green King (SGK) glove sold by 12 Jomac Canada of Quebec, Canada. The chore glove design provides warmth, mobility and grip 13 in oily environments. Padding has not previously been provided, however, on such chore 14 gloves to protect metacarpal bones from impact and pinch hazards. A need therefore exists for such padding that is effective on gloves, sleeves and other articles.

19 [0005] Figs. 2A and 2B are a perspective view and a top plan view, respectively, of the back of thumb impact pad in an embodiment of the invention;
21 [0006] Fig. 3 is a top plan view of the back of hand impact pad of Fig.
1 installed on the back of 22 hand side of a glove;
23 [0007] Fig. 4 is a top plan view of a back of hand pad installed on a glove in a second 24 embodiment of the invention;
[0008] Fig. 5 is a bottom plan view of a back of thumb pad installed on the glove of Fig. 4;

CA Application Blakes Ref: 10703/00001 I DETAILED DESCRIPTION OF EMBODIMENTS
2 [0010] While the present invention will be described below in terms of impact pads for/and 3 gloves, it is to be understood that the present invention may be employed in sleeves and other 4 articles.
[0011] A back of hand impact pad in a first embodiment of the present invention is indicated in 6 general at 10 in Fig. 1. A back of thumb impact pad of the first embodiment is indicated in 7 general at 12 in Figs. 2A and 2B. The impact pads 10 and 12 are preferably a lamination of a 8 padding material, such as cross-linked polyethylene foam, and fabric. As illustrated in Fig. 6, 9 the fabric layer 14 is positioned upon and laminated to the cross-linked polyethylene foam layer 16 so as to follow the contours molded into the padding material of Figs 1-28.
11 [0012] The cross-linked polyethylene foam (layer 16 of Fig. 6) preferably has a thickness 12 ranging from approximately 6 mm to 12 mm, prior to molding, and a weight ranging from 13 approximately 2 pcf to 4 pcf (pcf = pounds/ cubic foot). The impact pad (both back of hand and 14 back of thumb) may be constructed from standard or flame retardant cross-linked polyethylene foam. Alternative substances that may be used as the padding material include, but are not 16 limited to, ethyl vinyl alcohol, polyurethane and styrene based foams.
17 [0013] The fabric 14 (Fig. 6) selected can be knitted or woven. Ideally, the fabric is 18 approximately 4 osy to 8 osy weight (osy = ounces per square yard). The fabric 14 is selected 19 based on the environment in which the glove or sleeve is used. The fabric protects the impact foam from mechanical hazards such as abrasion and heat. Examples of suitable fabrics 21 include, but are not limited to, synthetic leathers, abrasion resistant knits and wovens 22 incorporating spandex fibers for stretch and conformity to the molding process.
23 [0014] Construction of the impact pads 10 and 12 of Figs. 1, 2A and 2B
preferably involves a 24 first step of laminating, via heat or adhesive, the impact foam in a flat form to the fabric. At this stage of the process, the laminated foam and fabric has a uniform thickness across the surface 26 of the composite prior to being subjected to heat and pressure inside a molded form. The flat 27 laminated materials are next placed in a single sided, concave mold where they are subjected to 28 heat and pressure, as is known in the art. Under heat and pressure the foam becomes fluid and 29 flows into the open mold cavities. As a result, impact pads having the shapes of Figs. 1 and 2 are created. Alternatively, with reference to Figs. 4 and 5, the back of hand impact pad 31 indicated at 17 and the back of thumb impact pad indicated at 19 may be created.
