Abstract

A ski-deck adapted to be easily knocked down for storage or transport is provided by having telescoping side frames that secure rollers on bearings for a looped carpet over a ski deck and adjustable fitting on vertical support rails secured to horizontal support rails in order to adjust the height and slope of the ski deck. Horizontal safety rails are secured to vertical support rails for a waist belt and ski-grips with a safety switch that will stop the motor drive for the looped carpet. A motor speed control potentiometer is provided on top of a vertical support rail for the ski student'"'"'s use in adjusting the simulated downhill skiing speed desired.

Claims

1. A simulated ski slope having an inclined ski deck and a continuous wide belt of material having a low coefficient of friction formed in a closed loop around rollers at the top and bottom of the inclined deck mounted on rotary axles that turn in bearings supported by a frame,

an assembly comprised of two rectangular side frames, each side frame having bearings at each end for said axles of said rollers, each side frame comprising a pair of telescoping box beams comprising the longer sides thereof, and means for securing said telescoping box beams in a position that holds said belt in a taut loop around said rollers having axles in said bearings, and

a support frame for said ski deck assembly comprising said side frames held in vertical planes with said rollers held in horizontal planes by said bearings supported by said side frames, said support frame further comprising a floor frame having two parallel longitudinal support rails and two transverse support rails, all in a horizontal plane;

four vertical support rails, two on each side of said ski deck assembly secured to said two parallel longitudinal support rails; and

two horizontal support rails, each passing between said pair of telescoping box beams of both side frames of said assembly, and each held at each end by a fitting on each of said vertical support rails, said fitting being positionable along the length of said vertical support rails in order to adjust the slope of said ski deck.

2. A simulated ski slope comprised of an assembly supported as defined in claim 1 by said four vertical support rails, further comprising a transverse rail extending between two of said vertical support rails opposite each other with respect to said ski deck, a slide tube fitted over said transverse rail and two ski-pole grips, one grip secured to each end of said slide tube.

3. A simulated ski slope comprised of an assembly supported as defined in claim 2 by said four vertical support rails, two slide tubes fitted over said transverse rail, and two ski-pole grips secured to each slide tube.

4. A simulated ski slope comprised of an assembly supported as defined in claim 1 including an electric motor means for driving one of said rollers to move said belt over said ski deck, further comprising a transverse rail extending between two of said vertical support rails opposite each other with respect to said ski deck, slide tube means fitted over said transverse rail, two ski-pole grips secured to said slide tube means, and at least one of said grips having a push-button safety switch protruding upwardly from said one of said grips, whereby said switch may be depressed by a skier'"'"'s thumb to cause said electric motor means to drive said belt and to cause said electric motor means to stop when said skier releases said push-button safety switch.

5. A simulated ski slope comprised of an assembly supported as defined in claim 1 including an electric motor means for driving one of said rollers to move said belt over said ski deck, further comprising ski poles, each ski pole having a grip at the upper end thereof, and at least one of said grips having a push-button safety switch protruding upwardly from said one of said grips, whereby said switch may be depressed by a skier'"'"'s thumb to cause said electric motor means to drive said belt and to cause said electric motor means to stop when said skier releases said push-button safety switch.

6. A simulated ski slope as defined in claim 1 including an electric motor means for driving one of said rollers to move said belt over said ski deck further comprising a speed-control potentiometer for said electric motor means, said speed-control potentiometer mounted at the top of one of said four vertical support rails.

7. A simulated ski slope as defined in claim 1 including at least one mogul comprised of a first section of carpet secured to said belt by non-elastic ties on the leading edge of said one section of carpet, and a plurality of sections of carpet under said one section, said plurality of sections of carpet being stacked and progressively smaller in the order stacked, each secured by non-elastic ties on the leading edge thereof to a preceding section of carpet, except the first which is secured by non-elastic ties on the leading edge thereof directly to said belt, said first section of carpet being large enough to overlay said stacked plurality of sections of carpet, and elastic ties securing the trailing edge of said first section of carpet to said belt.
