    摘要： An artificial ski surface construction includes a support surface having an energy absorbing base of elastomer thereon. A flexible sheath covers the energy absorbing base and includes a continuous surface having a fabric underside to contact the sheath with fibers extending upwardly therefrom to provide an artificial ski surface. A structure positions the support surface to form a slope and the continuous surface forms an endless belt which is mounted on rollers with motor means to rotate the rollers and move the continuous surface relative to the sheath and elastomer base.

    摘要： The specification describes a plastic ski track composed of interlocking track elements roughly rectangular in shape. Each track element contains a plurality of parallel rows of upright support members inclined from the vertical at an angle in the direction of the ski course. The elements may be fabricated by injection molding of a plastic composition, such as polyethylenebased compound.
