  • Patent number: 7028434
    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.
