Abstract
Abstract Apparatus for simulating skiing down a slope including a sloping platform mounted by the user in front of which is projected a picture of a ski slope accompanied by instruction as to how to traverse the slope. Means are connected to the platform for simulating the various movements a skier would execute in skiing down the slope. These movements are executed in accordance with the instruction accompanying the projection.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
208 words
Snow ski simulation apparatus comprising: a sloping platform for supporting a skier, means for projecting an image of a ski slope in front of said platform, and means connected to said platform for simulating the traverse of the ski slope image projected in front of said platform, said simulation means including means for reciprocably mounting the boots of a skier supported on said platform, said reciprocal mounting means including a harness for a pair of boots, a base plate on said platform below each of said harnesses, each of said harnesses including stop means for limiting the reciprocal movement of said harnesses relative to said base plate, a plurality of ball bearings mounted on each of said base plates, and means on said boot harnesses reciprocally receiving said ball bearings, means for rotatably mounting each of said base plates, said base plate rotation mounting means including a ball and socket universal joint, the ball of said joint being connected to said base plate, and the socket being on said platform, said socket being formed in the top of a cylinder, said cylinder including a chamber filled with hydraulic fluid and a fixed piston therein, said cylinder being reciprocal relative to said piston against the force of said fluid.
