Mat with Puzzle Function

Abstract

A mat with puzzle function is a four-sided pad. Each side has a toothed border with a succession of teeth. At least two cutting lines divide the mat into four blocks, in such a way that each block has an assembling edge with the complementary shape to connect with other blocks. The block of each mat can engage with another block of the same mat to form a puzzle mat set.

What is claimed is: 
     
         1 - 5 . (canceled) 
     
     
         6 . A floor mat comprising:
 a plurality of blocks, each block having a perimeter defined by a toothed border and two assembling edges,   wherein the plurality of blocks assemble jointly through the assembling edges and form the floor mat with a plurality of sides formed by the toothed border of each block, and   the assembling edges are defined by two cutting lines, each cutting line extending from a first side of the floor mat to a third side of the floor mat.   
     
     
         7 . The floor mat of  claim 6 , where in each cutting line extends from one corner of the floor mat to an opposing corner of the floor mat. 
     
     
         8 . The floor mat of  claim 6 , wherein the two cutting lines has an identical shape. 
     
     
         9 . The floor mat of  claim 6 , wherein the two cutting lines cross each other at a center of the floor mat. 
     
     
         10 . The floor mat of  claim 6 , wherein the two cutting lines are curved. 
     
     
         11 . The floor mat of  claim 6 , wherein the plurality of blocks have an identical shape. 
     
     
         12 . The floor mat of  claim 6 , wherein the two assembling edges of each block are a first assembling edge and a second assembling edge, the first assembling edge of one block engages the second assembling edge of an adjacent block. 
     
     
         13 . A puzzle piece comprising:
 a plurality of blocks, each block having a perimeter defined by a toothed border and two assembling edges,   wherein the plurality of blocks assemble jointly through the toothed border of each block and form the puzzle piece with an external border defined by the assembling edge of each block.   
     
     
         14 . The puzzle piece of  claim 13 , wherein the plurality of blocks assemble jointly through the assembling edges and form a floor mat with a plurality of sides formed by the toothed border of each block. 
     
     
         15 . The puzzle piece of  claim 13 , wherein the two assembling edges of each block have an identical shape. 
     
     
         16 . The puzzle piece of  claim 13 , wherein the assembling edges are curved.
