Abstract
Abstract An alpine ski simulator for reproducing the basic corporal movements involved in downhill skiing, comprising a frame which may be set at different angles relative to the horizontal plane, and a handrail for equilibrium purposes. A rotatable platform, horizontally mounted on the frame through a central shaft has roller means set between the platform and the frame to ease the rotation. A fixed band encircling the platform, guided between two pairs of posts, and connected to the frame, is provided for braking purposes. Adjustable means are attached between the band and the frame to increase or reduce the tension of the band against the platform and thus, vary the rotational speed of the platform.

Independent Claim
174 words
An alpine ski simulator comprising: a frame including adjustment means to adjust the inclination of the frame relative to a horizontal plane; a central shaft connected in a perpendicular, fixed relationship to the frame; a generally circular platform horizontally mounted on the frame, through the shaft, for rotation and including a ring shaped member mounted underneath said platform; roller means positioned between said platform and said frame to facilitate rotation; a fixed band encircling the ring shaped member and attached to the frame for braking purposes, to regulate the rotational speed of said platform; an inner pair and outer pair of guiding posts vertically attached on the frame, near of the perimeter of the platform, said inner pair of said posts the band against the ring shaped member of the platform the outer pair of said posts provide tensioning to said band; and, adjustable spring means connected between the band and the frame, to adjust the tension of the band against the ring shaped member, and thus, increase or reduce the speed of rotation.
