Abstract

A skiing simulator which includes a platform formed by an annular peripheral frame defining an opening in which there is suspended a disc. The disc is suspended by tension springs extending between the edge of the disc and the peripheral frame. A pair of openings having parallel longitudinal axes are defined in the disc, and sole plates are adapted to rotate about the longitudinal axes in respective openings. A parallelogram linkage extends between the sole plates to control the parallel rotational movement therof, and a damper is connected between the disc and the linkage in order to provide resistance to the rotational movement of the sole plates. Ski boot bindings are fixed to each of the sole plates for receiving ski boots. A skier utilizing the skiing simulator can simulate forward and rearward tilting as well as translational lateral body movements of skiing.

Claims

1. A skiing simulator comprising a platform, the platform including a peripheral frame and defining an opening, a sub-platform provided within the opening and suspension means mounting the sub-platform to the peripheral frame for relative universal directional tilting movement therewith, the suspension means including tension means extending between the peripheral frame and the sub-platform and normally maintaining the sub-platform in the plane of the platform, the simulator being characterized in that the sub-platform defines a pair of openings having parallel longitudinal axes and a pair of boot receiving harnesses, one in each opening, means for mounting a ski boot in alignment with the longitudinal axis of each respective opening and rotatably about the respective longitudinal axis, such that a person standing on the subplatform with a foot in each respective boot harness can simulate the body movement of a skier during downhill skiing.

2. A skiing simulator as defined in claim 1, wherein the boot receiving harnesses each include a sole plate, and the sole plate is mounted in its respective opening in the sub-frame for rotational movement about a longitudinal axis.

3. A skiing simulator as defined in claim 2, wherein each sole plate is mounted on a shaft which in turn extends in the longitudinal axis of the opening and is journalled at each end in bearing means mounted on the sub-platform.

4. A skiing simulator as defined in claim 2, wherein ski boot bindings are provided on each sole plate for engaging said ski boots.

5. A skiing simulator as defined in claim 1, wherein the sub-platform is in the form of a circular disc mounted within the opening defined by the frame, and tension coil springs extend from the peripheral frame to the edge of the disc to suspend the disc.

6. A skiing simulator as defined in claim 2, wherein a parallelogram linkage is provided between the sole plates, and damping means are provided between the sub-platform and the parallelogram linkage in order to provide resistance to the rotational movements of the respective sole plates.

7. A skiing simulator as defined in claim 1, wherein the platform is mounted to a portable base, including a plurality of legs connected to the peripheral frame, and detachable outrigger struts extend from the peripheral frame outwardly and downwardly therefrom to support, with the base, the platform in a position spaced above a support surface.
