Patent ID: 8266857

Claim:
An interlocked floor system comprising: multiple polymeric panels molded as an integral body having a planar top surface and a grid structure supporting the top surface and multiple interlocking side surfaces; each interlocking side surface having upwardly and downwardly facing steps, at least one of the downwardly facing steps have a convex projection on a bottom surface, at least one of the upwardly facing steps have a concave mating dimple on an upper surface; an over hang ledge formed as an extension of the planar top surface, thereby forming a cavity between the over hang ledge and the upper surface of each of the upwardly facing steps; an under hang ledge formed in a top surface of each of the downwardly facing steps allowing the downward facing steps of a first panel of the multiple polymeric panels to fit within the cavities of a second panel of the multiple polymeric panels; and a plurality of barbs, the barbs pointing upwardly along the planar top surface and the barbs interfacing with a layer of planar material placed on top of the top planar surface of the multiple polymeric panels, thereby maintaining a position of the planar material upon the planar top surface; whereas the steps of the side surfaces of the first of the multiple polymeric panels interlock to complementary steps of the second panel of the multiple polymeric panels.
