ABSTRACT:
A floor mat is composed of a multiplicity of rigid elongated rails arranged parallel to each other, each rail having a body portion adapted to receive a tread member and a coupling portion by which it is joined to an adjacent rail. The body and coupling portions are found by extrusion of a rigid high-impact strength thermoplastic polymeric material and are joined by a living hinge of a highly flexible thermoplastic elastomer formed by coextrusion with the body and coupling portions. Each rail includes at least two ribs along its underside laterally spaced apart from each other and adapted to support the rail on a surface, each rib being formed by coextrusion with the body and coupling portions and the living hinge of a soft, compressible thermoplastic polymeric material and serving as a cushion and an anti-slip element of the mat.
