Abstract:
1. An interlockable, modular tile having a central body of substantially resilient composition with a substantially planar top surface and peripherally disposed interlocks joined to the body for making adhesive-free interlocking connections with other, substantially identical, tiles, the tile comprising: first and second pairs of elongated peripheral edge portions, integral with the central body, of substantially rectangular cross-sectional shape disposed on different peripheral tile edges, the first pair of edge portions having intersecting longitudinal axes and joining to form one tile corner and the second pair of edge portions having intersecting longitudinal axes and joining to form an opposite tile corner, first and second interlock projections depending from respective underlying ones of said edge portions in alternating, longitudinally spaced-apart relationship, with said projections on said first pair of said edge portions extending in one direction and said projections on said second pair of said edge portions extending in an opposite direction, each of said projections comprised of a first sidewall section disposed substantially parallel to the longitudinal axes of its underlying edge portion and a pair of mutually opposed and inclined second and third sidewall sections extending at acute angles from said first sidewall section and joining together at a common apex, whereby the projections have substantially triangular shapes, and, wherein certain ones of said first projections are disposed on their underlying edge portion between adjacent pairs of said second projections with their sidewall sections in an inverted relationship relative thereto, whereby an open, arcuate channel of substantially U-shaped cross section is formed by their opposing sidewall sections for mating with inverted, second projections of another, substantially identical tile and thereby providing one set of female interlocks therefor.
