Description

[Detailed Description of the Invention] The present invention provides a ski with good rotational performance and high safety, and its structure will be described in detail with reference to the accompanying drawings as follows.

Corner parts 2 near the top and near the tail of a steel edge 1 attached to both edges of the lower surface of a ski board A are chamfered to form an edge slope part 3.

The length of this edge slope part 3 is adapted to ski techniques for beginners, intermediates, and advanced skiers, and the edge slope part 3 is extended over the snow-contacting part 7 to be longer for beginners. In the figure, reference numeral 4 indicates skis for beginners, 5 indicates skis for intermediate users, and 6 indicates skis for advanced users.

Originally, the edge of a ski plays the role of preventing the ski from skidding by applying an edge to the snowy slope.

When rotating, the user moves his/her weight onto the snowy slope to release the edge, and then the opposite edge is applied again to complete the rotation.

In other words, rotation is performed smoothly by switching the edges, but since beginners are less skilled at switching edges, conversely, if the edges get tight, the rotation cannot be performed smoothly and the machine may fall. It turns out.

The present invention solves this drawback by forming an edge surface part 3 by chamfering the top and tail corner parts 2 of the steel edge 1 attached to both edges of the lower surface of the ski A, so that the edge part 3 is chamfered. The length of the ski becomes shorter, resulting in a ski A that has less snag.

Of course, the angles at the corners are not rounded like in old wooden skis without steel edges, but even if the corners are chamfered, the steel edges themselves are present on both edges of the bottom of the ski. The edge action of biting into the snow surface is achieved, and skidding on a normal snowy slope can be prevented.

Furthermore, since the corner portions 2 are chamfered, the ski A does not have as many edges as beginners do, but it also prevents it from catching in bad conditions, making the ski A easier to rotate.

Therefore, by increasing the length of the chamfer over the snow-contacting portion 7 for beginners, the ski A becomes easier to rotate.

In addition, by chamfering the steel edges 1 near the top and tail, the steel edges on the top and tail of skis, which were common in conventional skis, can cut the opponent you collide with or cut yourself. This is an extremely safe ski that can prevent injuries.

Note that FIG. 1 shows a ski for beginners 4 in which the edge slope portion 3 is formed over almost the entire length, and FIG.
In this ski, edge slope portions 3 are formed near the top and near the tail, and in Fig. 3, edge slope portions 3 are formed near the top and tail while leaving the snow-contacting portion 7 for a ski 6 for advanced skiers. The purchaser selects one according to his/her own skiing skills, and the ski shown in Fig. 1 is most suitable for female beginners in particular, and has a corresponding commercial value.

Claims (1)

[Scope of Claim for Utility Model Registration] 1. An edge slope section is formed by chamfering the top and tail corners of the steel edges attached to both edges of the lower surface of the ski, and the length of this edge slope section is determined to be suitable for beginners. , a ski board characterized by having a slope part extended over the snow contact area for beginners to suit the skiing techniques of intermediate and advanced skiers. 2. The ski according to Claim 1 of the Utility Model Registration Claim, in which an edge slope portion is formed over substantially the entire length of the steel edge. 3. The ski according to Claim 1 of the Utility Model Registration, in which edge slopes are formed near the top and near the tail over the snow-contacting part of the steel edge. 4. The ski according to Claim 1 of the Utility Model Registration, in which the steel edge snow-contacting part is left and edge slope parts are formed near the top and the tail.
