Abstract
Abstract This invention relates to a protective device adapted to protect the hand, palm and wrist of a person while one is engaging in a sporting activity, such as skateboarding or football, and can also be used to retain the hand, palm, and wrist substantially immobile after an injury. The device has a contoured, generally rectangular shape constructed of a resilient, energy-absorbent material, such as plastic foam, which is coated or covered on at least one side with a covering layer. A bendable stiffening member is interposed between the covering layer and resilient material forming a sandwich-like construction. The peripheral edges of the resilient material and the covering layer extend beyond the peripheral edges of the stiffening member. The novel construction provides a generally cylindrical protective means when the device is worn. Suitable fastening means are provided to retain the device on the wearer's hand, palm and wrist.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
103 words
A protective device for a person's hand, palm and wrist having a generally rectangular shape of a person's hand and a sandwich-like construction comprising an outer layer of a tough, pliable material, an inner layer of energy absorbing material, and a bendable stiffening member, which is bendable about a palm and wrist, interposed between said outer and inner layers, the peripheral edges of said outer and inner layers being held together and the peripheral edges of said stiffening member disposed near said peripheral edges of said inner and outer layers, said device including securing means for retaining the device on a wearer's hand.
Claim 2
Dependent Claim
103 words
A protective device for a person's hand, palm and wrist having a generally rectangular shape of a person's hand and a sandwich-like construction comprising an outer layer of a tough, pliable material, an inner layer of energy absorbing material, and a bendable stiffening member, which is bendable about a palm and wrist, interposed between said outer and inner layers, the peripheral edges of said outer and inner layers being held together and the peripheral edges of said stiffening member disposed near said peripheral edges of said inner and outer layers, said device including securing means for retaining the device on a wearer's hand.
Claim 3
Dependent Claim
24 words
The device of claim 1 wherein said device comprises an additional layer of an energy-absorbing material bound to said inner layer having ventilation properties.
Claim 4
Dependent Claim
13 words
The device of claim 1 wherein said outer layer is a plastic material.
Claim 5
Dependent Claim
15 words
The device of claim 1 wherein said inner layer is a closed-cell plastic foam material.
Claim 6
Dependent Claim
14 words
The device of claim 1 wherein said stiffening member is an impact-resistant plastic material.
Claim 7
Dependent Claim
23 words
The device of claim 1 wherein said securing means comprises strap means adapted to pass through loop means disposed in said outer layer.
Claim 8
Dependent Claim
16 words
The device of claim 1 wherein portions of the device are retained together by tying means.
Claim 9
Dependent Claim
12 words
The device of claim 1 wherein the stiffening member is a metal.
Claim 10
Dependent Claim
89 words
A sandwich-like construction adapted to be used in devices for protecting parts of a human body, comprising a first layer of a tough, pliable plastic material, a second layer of an energy absorbing plastic foam material, a bendable stiffening member interposed between said first and second layers, the stiffening member being bendable about a part of a body, the peripheral edges of said first and second layers being held together, and the peripheral edges of said stiffening member disposed near said peripheral edges of said first and second layers.
Claim 11
Dependent Claim
89 words
A sandwich-like construction adapted to be used in devices for protecting parts of a human body, comprising a first layer of a tough, pliable plastic material, a second layer of an energy absorbing plastic foam material, a bendable stiffening member interposed between said first and second layers, the stiffening member being bendable about a part of a body, the peripheral edges of said first and second layers being held together, and the peripheral edges of said stiffening member disposed near said peripheral edges of said first and second layers.
Claim 12
Dependent Claim
24 words
The sandwich-like construction of claim 9 wherein a third layer of energy-absorging plastic foam material having ventilation properties is secured to said second layer.
Claim 13
Dependent Claim
29 words
The sandwich-like construction of claim 9 wherein the peripheral edges of said stiffening member are disposed inwardly from said peripheral edges of said second layer of energy absorbing material.
Claim 14
Dependent Claim
28 words
The device of claim 1 wherein the peripheral edges of said stiffening member are disposed inwardly from said peripheral edges of said second layer of energy absorbing material.
Claim 15
Dependent Claim
36 words
The device of claim 1 wherein the securing means hold the sandwich-like construction in a generally cylindrical shape encircling a hand, palm and wrist, thereby forming a rigid cylindrical shape and surface of the stiffening member.
Claim 16
Dependent Claim
38 words
A sandwich-like construction of claim 9 wherein the securing means hold the sandwich-like construction in a generally cylindrical shape encircling a part of a human body, thereby forming a rigid cylindrical shape and surface of the stiffening member.
