Foam mat with differently colored border

Abstract

A foam mat with a differently colored border includes an upper layer and a lower layer overlaid with the upper layer. The upper and lower layers are made of foaming materials of different colors, and each peripheral side of the foam mat is processed into an inclined edge where the lower layer extends further outward than the upper layer. The inclined edges show differently colored layers which are both easily identifiable and esthetically pleasing. The inclined edge at each peripheral side of the foam mat also provides a slope which reduces the chance of a user's feet hitting the foam mat by accident when the user is stepping on the foam mat.

1 . A foam mat with a differently colored border, comprising an upper layer and a lower layer overlaid with the upper layer, wherein the upper layer and the lower layer are made of foaming materials of different colors, and each peripheral side of the foam mat is processed to form an inclined edge in which the lower layer extends further outward than the upper layer. 
     
     
         2 . The foam mat of  claim 1 , wherein each said peripheral side of the foam mat is processed by cutting or grinding. 
     
     
         3 . The foam mat of  claim 1 , wherein the lower layer undergoes a foaming and forming process in which raw foaming materials of various colors are randomly arranged in a forming mold such that, after the foaming and forming process, the lower layer of the foam mat is formed with an irregular pattern. 
     
     
         4 . The foam mat of  claim 1 , wherein the inclined edge at each said peripheral side of the foam mat shows differently colored layers attributable to the different colors of the upper layer and the lower layer. 
     
     
         5 . A foam mat with a differently colored border, comprising an upper layer, at least one intermediate layer overlaid with the upper layer, and a lower layer overlaid with the intermediate layer, wherein each two adjacent said layers are made of foaming materials of different colors, and each peripheral side of the foam mat is processed to form an inclined edge in which the intermediate layer extends further outward than the upper layer and the lower layer extends further outward than the intermediate layer. 
     
     
         6 . The foam mat of  claim 5 , wherein each said peripheral side of the foam mat is processed by cutting or grinding. 
     
     
         7 . The foam mat of  claim 5 , wherein the inclined edge at each said peripheral side of the foam mat shows differently colored layers attributable to the different colors of each two adjacent said layers. 
     
     
         8 . The foam mat of  claim 5 , wherein at least one of the upper layer, the intermediate layer, and the lower layer of the foam mat undergoes a foaming and forming process in which raw foaming materials of various colors are randomly arranged in a forming mold such that, after the foaming and forming process, the at least one layer of the foam mat is formed with an irregular pattern.
