Abstract: A thin flexible floor mat system is configured to resist penetration by high heeled shoes and be capable of being easily rolled up in long segments. The floor mat is constituted by a series of small square sections and are connected together with connectors that permit easy deployment and removal of the mat system by detaching segments of the mat from each other. The mat is flexible but resists penetration from high heels and other forms of traffic by virtue maintaining of a predetermined amount of flexibility through the use of auxiliary supports. Further stability is provided by one-piece ramp corners.

Abstract: A rubber or plastic floor mat has a series of parallel upper ribs (130) on its upper surface which define slots (110) in which respective strips (10) or carpeting or the like are removably held. The strips are retained along their lengths by retaining means which run continually or continuously along the slots. The strip retainers include hook-and-loop fastening (e.g., VELCRO), and/or overhanging edges above the strip edges, preferably formed in one-piece fashion along the side of the upper ribs adjacent the slots. The overhangs may be interrupted, e.g., crenelated as seen from above, and may include bevels.
