Abstract

Abstract A modular floor covering system comprising a plurality of base mats removably connected together by means of a plurality of alternately and successively arranged indentations and projections formed along the outer peripheral edge of each mat and correspondingly configured such that the projection of one mat is removable mounted within the indentations of an adjacently positioned and connected mat. Surfacing, either in the form of substantially flexible or resilient tufts or substantially rigid tile members are secured to the upper planar surface of the mat by means of a plurality of fingers extending upwardly from the planar surface of the mats so as to engage a socket located in the surfacing, wherein either the tugs or the rigid tiles are spaced in predetermined relation to one another so as to substantially cover the upper planar surface of the base mats.
