Joint support device

Abstract

A joint support device is provided. The joint support device may include a first tubular layer and a second tubular layer both made of crisscrossing fibers. The crisscrossing fibers of the first tubular layer may be oriented in a spiral in a first direction and the crisscrossing fibers of the second tubular layer may be oriented in a spiral in an opposite direction of the first direction. The first and second tubular layers may be layered together and may be attached to an existing elastic knee brace.

What is claimed is: 
     
         1 . A joint support device comprising:
 a first tubular layer having a top and a bottom, wherein the first tubular layer comprises a plurality of first crisscrossing fibers, wherein the first crisscrossing fibers spiral from the bottom to the top;   a second tubular layer having a top and a bottom, wherein the second tubular layer comprises a plurality of second crisscrossing fibers, wherein the second crisscrossing fibers spirals from the bottom to the top in an opposite direction of the first crisscrossing fibers,   wherein the first tubular layer and the second tubular layer overlap one another.   
     
     
         2 . The joint support device of  claim 1 , wherein the crisscrossing fibers of the first and second tubular layers comprise elastic fibers and inelastic fibers. 
     
     
         3 . The joint support device of  claim 2 , wherein the elastic fibers are substantially parallel to each other and the inelastic fibers are substantially parallel to each other. 
     
     
         4 . The joint support device of  claim 1 , further comprising a knee brace, wherein the knee brace is within and attached to the joint support device. 
     
     
         5 . The joint support device of  claim 4 , wherein the knee brace comprises a body portion forming an opening near a center of the body portion. 
     
     
         6 . The joint support device of  claim 5 , wherein the top and bottom of the first and second tubular layers are sewn to the knee brace. 
     
     
         7 . The joint support device of  claim 1 , further comprising a plurality of layered first and second tubular layers.
