DUAL ALPINE SKI

摘要

The inventive double mountain ski relates to sport equipment, more specifically to mountain skiing equipment and can be used as an alpine ski and a snowboard. The inventive useful model is characterised in that the dual alpine ski consists of two movable parts (sliding surfaces) mechanically connected to each other and to a flexible central beam which is provided with a boot binding mounted thereon by means of movable elements (trapezes) having a special structure. Said movable elements make it possible to dispose the sliding surfaces in a parallel position to each other and with respect to the outsole of the boot in a straight position and in the ski edges. The inventive design structure makes it possible to reduce the length of ski without reducing the length of a working edge. As a snowboard, the dual ski provides high stability since the mass of a skier is distributed on two parallel edges.
