Cushion having enhanced friction

Abstract

A cushion includes a main body, wherein the lowermost or outermost layer of the main body has a protruding meshed surface by provision of the mesh layer so as to enhance the surface friction coefficient of the cushion, thereby providing an anti-skid effect. In addition, the main body of the cushion has a protruding meshed surface so as to increase the strength of the cushion, thereby enhancing the lifetime of the cushion.

1 . A cushion, comprising a main body including: 
 a sponge layer;    a first TPU (thermoplastic polyurethane) layer mounted on an upper portion of the sponge layer;    a cloth layer mounted on the first TPU layer;    a second TPU layer mounted on a lower portion of the sponge layer;    a mesh layer mounted on the second TPU layer; and    a third TPU layer mounted on the mesh layer.    
   
   
       2 . The cushion in accordance with  claim 1 , wherein the mesh layer has a surface formed with a plurality of meshes.  
   
   
       3 . The cushion in accordance with  claim 2 , wherein each of the meshes of the mesh layer has a circular, square, diamond or rectangular shape.  
   
   
       4 . The cushion in accordance with  claim 1 , wherein the mesh layer is made of a polyester.  
   
   
       5 . The cushion in accordance with  claim 1 , wherein the mesh layer is made of a nylon.  
   
   
       6 . The cushion in accordance with  claim 1 , wherein the first TPU layer, the cloth layer, the second TPU layer, the mesh layer and the third TPU layer are sealed at a periphery thereof.  
   
   
       7 . The cushion in accordance with  claim 1 , wherein the mesh layer and the third TPU layer are fused and mixed with each other, so that the third TPU layer is integrally formed with the mesh layer to have a protruding meshed shape by provision of the mesh layer.  
   
   
       8 . The cushion in accordance with  claim 1 , wherein the mesh layer has a peripheral length smaller than that of the second TPU layer and the third TPU layer, so that the periphery of the mesh layer does not reach the sealed periphery of the second TPU layer and the third TPU layer.  
   
   
       9 . The cushion in accordance with  claim 1 , wherein the mesh layer has a peripheral length equal to that of the second TPU layer and the third TPU layer, so that the periphery of the mesh layer reaches the sealed periphery of the second TPU layer and the third TPU layer.  
   
   
       10 . The cushion in accordance with  claim 9 , wherein the second TPU layer, the mesh layer and the third TPU layer are sealed at the periphery thereof.  
   
   
       11 . A cushion, comprising a main body including: 
 a sponge layer;    a first TPU (thermoplastic polyurethane) layer mounted on a peripheral portion of the sponge layer;    a mesh layer mounted on a peripheral portion of the first TPU layer; and    a second TPU layer mounted on a peripheral portion of the mesh layer.    
   
   
       12 . The cushion in accordance with  claim 11 , wherein the mesh layer is made of a polyester or nylon.  
   
   
       13 . The cushion in accordance with  claim 11 , wherein the first TPU layer, the mesh layer and the second TPU layer are sealed at a periphery thereof.  
   
   
       14 . The cushion in accordance with  claim 11 , wherein the mesh layer and the second TPU layer are mixed with each other, so that the second TPU layer is integrally formed with the mesh layer to have a protruding meshed shape by provision of the mesh layer.
