Strip foam floor mat

Abstract

A strip foam floor mat includes a rectangular main body with two long sides and two short sides, and each side has plural complementarily shaped first convex teeth and first notches disposed apart from one another, a pair of complementarily shaped second convex tooth and second notch disposed at each corner at both ends of each side, and a pair of complementarily shaped third convex tooth and third notch disposed adjacent to each other and at positions of the multiple length of the short side along each long side, and the third convex tooth is in the same protruding shape of the second convex tooth when the two main bodies are spliced, and the third notch is the same concave shape of the adjacent second notch when the two main bodies are spliced.

What is claimed is: 
     
         1 . A strip foam floor mat, comprising:
 a rectangular main body, including two long sides and two short sides, and the long side having a length equal to a multiple of the length of the short side, and the multiple being at least three;   a plurality of first convex teeth and first notches, disposed with an interval apart from one another on each of the long sides and short sides, and their concave and convex shapes being complementary to one another;   a second convex tooth and a second notch, disposed at four corners of the main body and at both ends of each of the long sides and short sides, and the second convex tooth of each long side is disposed immediately next to the second notch of the adjacent short side, and the second convex tooth of each long side is disposed away from the second convex tooth of the adjacent short side, and the concave and convex shapes of each second convex tooth and each second notch being complementary to each other; and   a third convex tooth and a third notch, disposed at positions of the multiple length of the short side along each long side and immediately next to each other, and the concave and convex shapes of each third convex tooth and each third notch being complementary to each other, and the third convex tooth being in the same shape as that of the protruding second convex tooth when splicing the second convex teeth of the two main bodies, and the third notch being in the same shape as that of the concave adjacent second notch when splicing the second convex teeth of the two main bodies.   
     
     
         2 . The strip foam floor mat of  claim 1 , wherein each of the first convex teeth has a bevel expanded outwardly from a root portion on both sides of each first convex tooth respectively, and ends of the two bevels are cut and aligned precisely with each other to form a plane. 
     
     
         3 . The strip foam floor mat of  claim 1 , wherein one side of each second convex tooth has a first bevel expanded outwardly from a root portion, and the other side of said each second convex has a relatively shorter second bevel expanded outwardly from a root portion, and a third bevel retracted at an acute angle from the second bevel, and ends of the first bevel and the third bevel are cut and aligned precisely with each other to form a plane. 
     
     
         4 . The strip foam floor mat of  claim 1 , wherein one side of each third convex tooth has a first bevel expanded outwardly from a root portion, and the other side of said each third convex tooth has a third bevel retracted from a root portion, and ends of the first bevel and the second bevel are cut and aligned precisely to form a plane.
