Coupling member for floor covering sections

Abstract

A floor covering, as for indoor public walking areas, being made up of sections, each section being substantially rectangular in plan, having a fairly narrow width and being disposed in closely spaced parallel relationship. Coupling members not unlike double hinges connect adjacent sides of the sections, the coupling members being particularly arranged to permit a compact rollup of the sections for cleaning purposes.

What is claimed is: 
     
       1. A floor covering consisting of coupled sections, having in combination a floor covering section substantially rectangular in plan,   a flange formed at each side edge portion of said section,   each flange having a longitudinal bore therethrough, said bores respectively having oppositely facing slots,   a coupling member comprising   a pair of closely spaced rods,   a web connecting said rods, said web having a thickness less than the height of said slots,   said rods respectively being disposed through adjacent pairs of said slots connecting a pair of said sections.[., and.].   .Iadd.said rods having rotary movement in said slots, and   a tread surface carried by said sections.   
     
     
       2. The structure of claim 1, including means securing said rods within said bores preventing relative longitudinal movement thereof. 
     
     
       3. The structure of claim 1, wherein said web has cut out spaces therein. 
     
     
       4. The structure of claim 1, wherein said flanges having a recessed area therebetween, and a tread including said tread surface disposed into said recessed area.
