ABSTRACT:
The present device is a roller ski that closely simulates the sliding, edging, turning and weighting characteristics of a snow ski. The roller ski is comprised of an exterior frame with pivotally mounted skate rollers that are inclinationally biased in the longitudinal direction to the ski and an interior platform which has a skateboard truck or similar rollers and which is pivotably hinged to the exterior frame along the longitudinal center line of the ski. The pivoting rollers on the exterior frame are attached to a caster mounted to a horizontal plate that is springily hinged to permit forced rotation about a horizontal transverse axis on the bottom side of the exterior frame to which the caster is attached. Consequently, weighting of the ski depresses the pivoting rollers, which are continuously in contact with the ski surface; whereas the rollers on either side of the skateboard truck make contact with the ski surface if the interior platform is tilted about the longitudinal center line of the ski. This particular combination of roller, hinge, platform and pivoting elements provide an effective simulation of conventional downhill snow skiing on a hard smooth surface such as cement pavement or blacktop.
