Abstract
Abstract This invention relates to protective cast devices for various parts of the body. The protective cast device of the present invention comprises a thin relatively rigid bendable lightweight closed cell member on which straps are fixed to form and hold the device about a body part. Once the device is bent and secured in one direction, it resists bending in any other direction. The member has a relatively more dense outer skin and a relatively less dense and more soft inner surface.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
123 words
A protective cast device adaptably to be worn around a part of a person's body, said device having a sheet-like planar contoured shape adapted to conform generally, substantially in the form of a cylinder, to the shape of the body part when said device is worn and secured around said body part, said device comprising a lightweight, thin, relatively stiff non-memory plastic foam material member which tends to resist bending, which tends to retain its bent shape after being bent and which, when curved in one direction, resists curving in any other direction and fastening means connected to the plastic foam member for maintaining the member curved in one direction around a body part whereby the member resists bending in any other direction.
Claim 2
Dependent Claim
123 words
A protective cast device adaptably to be worn around a part of a person's body, said device having a sheet-like planar contoured shape adapted to conform generally, substantially in the form of a cylinder, to the shape of the body part when said device is worn and secured around said body part, said device comprising a lightweight, thin, relatively stiff non-memory plastic foam material member which tends to resist bending, which tends to retain its bent shape after being bent and which, when curved in one direction, resists curving in any other direction and fastening means connected to the plastic foam member for maintaining the member curved in one direction around a body part whereby the member resists bending in any other direction.
Claim 3
Dependent Claim
18 words
The protective cast device of claim 1 wherein the plastic foam member comprises a closed cell foam member.
Claim 4
Dependent Claim
21 words
The protective cast device of claim 2 wherein the closed cell foam member comprises a low density closed cell foam member.
Claim 5
Dependent Claim
41 words
The protective cast device of claim 2 wherein the closed cell foam member has an outer relatively more dense self skin formed on the member on a side thereof away from a body part around which the protective cast is bent.
Claim 6
Dependent Claim
22 words
The protective cast device of claim 4 wherein the fastening means comprise strap means connected to the relatively more dense outer skin.
Claim 7
Dependent Claim
43 words
The protective cast device apparatus of claim 4 further comprising a relatively less dense closed cell plastic foam material connected inwardly of the closed cell foam member on a side thereof toward the body part around which the protective cast device is bent.
Claim 8
Dependent Claim
36 words
The apparatus of claim 2 further comprising a relatively less dense closed cell plastic foam material on a side of the closed cell foam member facing the body part around which the protective cast is bent.
