ABSTRACT:
A foot mat comprises a multiplicity of elongated rail members formed by coextrusion of a substantially rigid polymeric material and a compressible polymeric material. Each rail member has a rigid tread-supporting web portion, at least two rigid leg portions, which are adapted to support the tread-supporting web portion stably on a surface, a cushion portion of the compressible material on the bottom of each leg portion, and a pair of rigid bulbous coupling portions of the substantially rigid material, one on each side of the tread-supporting web portion. Each coupling portion is substantially longitudinally coextensive with the tread-supporting web portion and extends generally laterally outwardly from the tread-supporting web portion. A tread member is received on the top of the tread-supporting web portion of the rail member. Each adjacent pair of rail members is joined by an elongated coupling member formed by extrusion of a metal or a polymeric material, each coupling member having a web portion and a substantially longitudinally continuous socket portion on each side of the web portion, each socket portion defining an undercut groove that opens generally laterally outwardly with respect to the web portion and receives a coupling portion of an adjacent rail member such that adjacent rail members are coupled to each other by a coupling member for articulation, whereby the mat can be rolled up.
