SKI

摘要

The invention relates to sports equipment and means mainly for moving on snow. A ski (or snow-board) has at least one bent end, an upper surface with a bearing stand for feet and a sliding surface embodied in the form of a single or several longitudinal cylindrical vaulted. The adjacent vaulted elements are separated by a comb with sharp bottom edge placed under the bearing stand. The comb gradually tapers at least one bent end of the ski. The comb gradually diminishes also to the rear end of the ski if it is bent like the head. In the preferred embodiment the sliding surface of the ski is formed with three longitudinal cylindrical vaulted elements. In this case, on the ski cross-section top points of two bordering vaulted elements coincide with bordering edges. The proportion between the height of the cylindrical vaulted elements and the distance between the bottom edges of the adjacent combs is not less than 1:2.5. The sliding surface can be formed with two longitudinal cylindrical vaulted elements. In this case, the sharp bottom edge of the comb is situated on the axis of symmetry of the ski.
