Abstract
A flooring system includes multiple polymeric panels that are interlocked into a floor system and then covered with a material such as carpet and artificial turf. A top surface of the polymeric panels includes barbs to hold the material from moving laterally during use.
Claims14
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.

An interlocked floor comprising:
- multiple polymeric panels molded as an integral body having a planar top surface and at least one interlocking side surfaces;
- each of the at least one interlocking side surfaces having upwardly and downwardly facing steps, at least one of the downwardly facing steps having a means to interlock on a bottom surface, at least one of the upwardly facing steps having a mating means to interlock on an upper surface;
- an over hang ledge extending from the planar top surface and 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 such that the downward facing step of a first panel of the multiple polymeric panels fits within the cavity of a second panel of the multiple polymeric panels;
- and
- a means for maintaining a layer of planar material in place on the top planar surface of the multiple polymeric panels, thereby reducing lateral movement of the planar material with respect to the planar top surface of the multiple polymeric panels;
- whereas the steps of the side surfaces of the first panel interlock with complementary steps of the second panel.
