  • Patent number: 4497854
    Abstract: An artificial surface for simulated cross-country skiing comprising an elongate flat flexible base and a multiplicity of extruded strips of synthetic resin material forming relatively stiff smooth-surfaced blade-like members secured to and substantially covering one face of the base. The blade-like members project generally perpendicularly from the base except in two generally parallel spaced-apart zones extending longitudinally of the base where the blade-like members are bent over in one direction extending generally lengthwise of the base to provide a pair of generally parallel ski tracks along the base. The base is adapted to be placed on the ground with the blade-like members facing upwardly and the bent-over blade-like members pointing in a direction opposite the direction of ski movement along said tracks.A method of making the artificial surface, and a method of using it are also disclosed.
