A floor mat is composed of a multiplicity of rigid elongated rails (10) arranged parallel to each other, each rail (10) having a body portion (12) adapted to receive a tread member (13) and a coupling portion (14) by which it is joined to an adjacent rail. The body and coupling portions (12, 14) are found by extrusion of a rigid high-impact strength thermoplastic polymeric material and are joined by a living hinge (38) in the form of a thin strand of a highly flexible thermoplastic elastomer formed by coextrusion with the body and coupling portions (12, 14) and constituting a distinct bending line between the body portion (12) and the coupling portion (14). Each rail (10) includes at least two ribs (34) along its underside laterally spaced apart from each other and adapted to support the rail (10) on a surface, each rib (34) being formed by coextrusion with the body and coupling portions (12, 14) and the living hinge (38) of a soft, compressible thermoplastic polymeric material and serving as a cushion and an anti- slip element of the mat. |
