Winter sports device having two parallel sliding runners

摘要

The standing plate (1) and the two sliding runners (3) of a winter sports device are mounted in a frame (2) so as to be swivellable in each case about a longitudinal axis. A train of gears connects the standing plate (1) to the sliding runners (3) in such a way that a swivel movement of the standing plate (1) is converted to a corresponding swivel movement of the two sliding runners (3). The sliding runners (3) have upwardly curved ends (3a, 3b) and a central region (3c) of the runners which is curved in the opposite direction. Each inside edge (4) of the runners has a straight guide edge. The outside edges (5) of the runners are curved in a concave manner with a curvature which increases towards the ends of the runners. <IMAGE>
