Tongue and Groove Interlocking Pavers

Abstract

Multilayered pavers comprise adjoining outer sections of male components that are adjacent to each other with opposite and adjacent outer sections that define female voids that comport to male sections of the pavers. The multiple layer or three layer approach allows for multiple points of contact and retention of the pavers. Slanted top and bottom sections of protrusions allow for ease of insertion of one paver into the other. A cambered perimeter edge of a top layer of the paver allows for ease of attachment to machinery sometimes used to transport each paver to a desired spot and for insertion into an adjacent paver.

What is claimed is: 
     
         1 . A multilayered paver comprising:
 a) a first layer comprising a top surface having cambered edges;   b) two adjacent sides having male protrusions and two opposite and adjacent sides defining female voids;   c) the two sides having male protrusions comprising:
 i) the first layer protruding past a second layer 
 ii) a third layer protruding past the second layer 
   d) the two sides having female voids, the first void defined by the top surface protruding past the second layer and the second void defined by the second layer protruding past a lower third layer.   
     
     
         2 . The multilayered paver of  claim 1  wherein the top and bottom surface of the third layer are slanted. 
     
     
         3 . The multilayered paver of  claim 2  wherein the surfaces defining the second void and slanted to comport with the top and bottom surface of the third layer. 
     
     
         4 . The multilayered paver of  claim 3  in the shape of a square. 
     
     
         5 . The multilayered paver of  claim 3  in the shape of a rectangle.
