  • Patent number: 6435101
    Abstract: A strong, flexible and vandalism-resistant panel is provided. The panel has a flexible interwoven skeleton structure that is embedded in a layer of polymer material. The skeleton structure is formed from a generally parallel arrangement of linear cross-members interconnecting adjacent links. The links are in the form of a triangular wave pattern and include a plurality of link elements interconnected at their opposed ends or peaks by alternately spaced transverse curves or folds. The linear cross-members are nested in the transverse curves of adjacent links to join the adjacent links. The panel of the present invention is particularly useful as a panel used to cover the space between two adjacent railroad car sections. The formed panels are flexible, cannot be dented, are substantially cut-proof, and are highly vandalism-resistant.

  • Patent number: 6067911
    Abstract: A strong, flexible and vandalism-resistant panel is provided. The panel includes a flexible wire skeleton structure such as a chain link structure embedded in a layer of polymer material such as rubber, synthetic rubber or another suitable polymer material. The chain link structure is made from parallel flat helical link sections connected by curved cross-sections. The panel of the present invention is particularly useful as a curtain for a roll-up door or for panels used to cover the space disposed between two adjacent railroad car sections. The formed panels are flexible, cannot be dented, are substantially cut-proof and are highly vandalism-resistant.
