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.

主权项

1. A snowboard comprising a board for mounting two bindings on the board's surface at a distance apart corresponding to approximately ⅓ of the board's length, where the board is provided with inwardly curved edge portions, the board having greater width at both ends at the transition (E, V) to the tips than at the middle (I), wherein the tip includes a skate plat, which during normal running on snow functions as a part of the tip, but which when performing certain tricks functions as a part of a central sliding surface, where the skate plate is located a few cm in front of the ordinary sliding surface in an area (C) between a skate plate (D) and an area (B), and between the beginning of the skate plate (D) and the end of the ordinary sliding surface (E) there is a shorter area where the sole surface is curved upwards, where the skate plate (C) relative to the ordinary sole surface has an approximately straight form so that the skate plate's angle to the surface has essentially a constant rising over the skate plate, where the area (B) in front of the skate plate is curved further upwards in a front tip, with the result that the sole in the front tip creates an increasing angle with the surface again, viewed in the snowboard's longitudinal direction.
