Abstract

Knee and elbow braces arranged to fit all sizes of persons, Each brace is formed of a generally planar elastomeric, e.g., fabric-covered-neoprene, base member and a generally planar elastomeric, e.g., fabric-covered-neoprene, spider member attached to the base member. The base member includes two upper mounting straps, and two lower mounting straps to mount the brace on the person'"'"'s joint. Each of the upper mounting straps is arranged to be wrapped in opposite directions around the limb above the joint to be protected. The lower mounting straps are arranged to be wrapped in opposite directions around the limb below the joint. The mounting straps include VELCRO® fasteners to hold the straps in place. When so wrapped the straps define cut away areas to prevent bunching of the material making up the brace when the joint is flexed. The spider member includes two upper and two lower tension straps which are arranged to be releasably secured by VELCRO® fasteners to respective ones of the mounting straps to effect the customized adjustment of tension provided by the brace to the joint. The spider member also provides cushioning and thermal insulation to the joint.

2. The brace of claim 1 wherein said brace comprises a knee brace, with the joint being the knee, and wherein said central portion of said base member and said middle portion of said spider member are padded and each includes an opening therein, with said openings being aligned with each other to accommodate the patella of the knee of the person therein.

3. The brace of claim 1 wherein said elastomeric material comprises neoprene.

4. The brace of claim 1 wherein said neoprene is covered by a fabric.

5. The brace of claim 1 wherein said releasable securement means comprise VELCRO®

means.

6. The brace of claim 1 wherein said first upper securement means comprises a patch of a multi-hook component secured to said first upper mounting strap and a fabric portion on said second upper mounting strap to which said multi-hook component may be releasably secured, and wherein said first lower securement means comprises a patch of a multi-hook component secured to said second lower mounting strap and a fabric portion on said first lower mounting strap to which said multi-hook component may be releasably secured.

7. The brace of claim 6 wherein said base member comprises an outer surface and wherein said entire outer surface forms said fabric portion.

8. The brace of claim 1 wherein said base member comprises a fabric outer surface, wherein said spider member comprises a inner surface, and wherein said second upper releasable securement means comprises a patch of a multi-hook component secured to the inner surface each of said tension straps for releasable securement to the fabric outer surface of said base member.

9. The brace of claim 6 wherein said base member comprises a fabric outer surface, wherein said spider member comprises a inner surface, and wherein said second upper releasable securement means comprises a patch of a multi-hook component secured to the inner surface each of said tension straps for releasable securement to the fabric outer surface of said base member.

10. The brace of claim 1 wherein said brace comprises an elbow brace, with the joint being the elbow, and wherein said central portion of said base member and said middle portion of said spider member are padded.

21. The brace of claim 1 wherein said releasable securement of said mounting straps together is by use of multi-hook and multi-loop fastening means.

14. A brace for a limb of a person, the limb having an upper portion, a lower portion, and a flexible joint therebetween, said brace comprising:
