A modular tile for interlocking with other similar tiles to form a floor covering which provides enhanced traction at its playing surface and improved tolerance to sudden lateral movement. The tile comprises a plastic support grid having rectangular configuration bounded by a perimeter wall and including a repeating pattern of intersecting cross members with interstitial openings formed inbetween. A plurality of support legs are coupled to a base side of the cross junctions in general perpendicular orientation. Interlock structure is coupled to and extends outward from the perimeter wall to enable removable attachment with other modular tiles of similar design. The interlock structure provides a continuous, uniform displacement gap between adjacent perimeter walls which establishes a separation distance between the range of 0.5 to 2 millimeters, and also provides a yielding response to absorb lateral forces. A continuous sheet of plastic provides a flat surface cap to the tile, which enables its use as part of a continuous flat athletic floor covering.

An array of interlocked modular tiles forming a floor covering which provides enhanced traction at its playing surface and improved tolerance to sudden lateral movement, each of said interlocked tiles comprising: a plastic support grid having a rectangular configuration bounded by a perimeter wall on four sides and including a repeating pattern of intersecting cross members of common corresponding dimensions integrally formed and extending inward from the perimeter wall and joined at cross junctions along a common plane with interstitial openings formed therebetween; a plurality of support legs of common length integrally coupled to a base side of the cross junctions in general perpendicular orientation with respect to the support grid; interlock means coupled to and extending outward from the perimeter wall to enable removable attachment of additional modular tiles of similar design at corresponding edges thereof; said interlock means being coupled to interlock means of each adjacent tile in the array and providing a continuous, uniform displacement gap between adjacent perimeter walls, said gap providing a static separation distance within the range of 0.5 to 2.0 mm, said separation distance being established by a biased position on the interlocking means which yields in response to lateral forces imposed at the tile along a perpendicular orientation with respect to the attached perimeter wall to collapse or extend the gap and thereby absorb the lateral forces, said interlock means providing a restoration force to return to the biased position and desired gap range; and a continuous sheet of plastic integrally formed in uniform thickness with a top edge of the support grid to provide a flat surface cap bounded at its edges by the perimeter walls of the tile.
