  • Patent number: 3959542
    Abstract: An artificial ski matting wherein a plurality of ski mats may be interlocked to form an artificial skiing surface. Each mat includes a base ski support surface and an plurality of spaced pegs having flexible "fluff" fingers on each peg. A second plurality of spaced pegs are interposed on the mat and having flexible "turn" fingers on each peg. The "fluff" fingers form a generally horizontal ski surface permitting skis to sink into the fluff fingers and track on the mat as a ski would do in natural snow. The "turn" fingers form a generally horizontal ski surface lower than the first-mentioned horizontal ski surface permitting skis to dig into the mat and "turn" thereon. Finally, the base ski support surface supports the skis when they dig down into the mat, such as when sufficient centrifugal force is created either in a dip or turn while skiing. In this manner, the effect of compaction of natural snow is created.BACKGROUND OF THE INVENTION1.
