SNOWBOARD

摘要

The present invention is based on the combination of a snowboard with a 3- dimensional sole which wholly or partly has a tripartite sliding surface in the portion between the transition to the tip(s) and the binding fastening(s), in addition to which the board is equipped with an additional special 3 -dimensional geometry in the tip(s), in order to continue the existing uplift in the lateral sliding surface (5), thereby ensuring better uplift and thus better glide and greater speed in loose snow, a combination which provides quite unique riding characteristics. The tip of the snowboard is designed in such a manner that it presses the snow under the board more efficiently, lifting it further up from the snow than an ordinary tip. When riding straight ahead, this is best accomplished by using what is called here a skate plate, with an almost straight portion in the tip, providing an extended tip at a moderate angle to the surface and thereby extremely careful treatment of the snow while keeping the tip above the snow. When turning, an improved uplift in the tip is achieved by successively increasing the angle between the central sole surface (2) and the lateral sole surface (6) in the tip from the end of the sliding surface a few cm forwards in the tip, with the result that during edging the lateral sole surface lies substantially flatter against the snow further forward in the tip than at the transition to the tip, thereby more efficiently pressing the snow under the snowboard and not to the side, thus causing the board to also glide better during turning. Skate plate (3) is only used where the board is to be used principally on rails and boxes in parks, and good riding characteristics also require to be retained during normal riding on the ground. Thus the solution is to integrate a plateau (3) between the ordinary sliding surface (1) and a somewhat more modest front tip (4) on the board, the point being that when riding on snow this plateau (3) should function as a part of the nose, while during active use of the plateau on rails and boxes it has a separate function as contact surface against the surface when on other snowboards the trick in question normally involves the use of the front part of the sliding surface (1). This concept can best be employed with a certain degree of regular camber between E-E and V-V. However, it may also be envisaged used in combination with boards without camber, or even reverse camber in this area. The characteristics will be further improved by exploiting the concept of a tripartite sliding surface, with the result that the steel edges are already raised on the inside of the tip(s), thereby ensuring a gentler rate of increase in the lateral sole surfaces (6) in the tip(s) and enabling the tip to glide with less resistance, particularly during turning.
