Description

[Detailed Description of the Invention] The present invention relates to an improvement of a ski for volleyball skiing used in freestyle ski competitions. As a recent trend in ski competitions, freestyle competitions are becoming more common, and within this, an event called volleyball skiing is becoming particularly popular.
Short skis are used in this event of valley skiing, but in the past there were not many skis specifically designed for this event on the market, so
Currently, competitors use short skis or junior skis that suit them. Furthermore, some skis that are commercially available as skis exclusively for the valley skiing event have only wider side cut shapes than conventional skis, and have not been specially improved for the valley skiing event. Therefore, as shown in Fig. 3, in a performance often performed in the valley ski event, a competitor 5 pushes a stock 6 onto the snow surface 7 and lifts his body, and in doing so, the tip part 8 of the ski Press the tip part 8 of the ski against the snow surface.
In conventional skiing, maneuvers such as ``standing on tiptoe,'' which involves doing a handstand using the fulcrum as a fulcrum, and ``turning on tiptoe'', in which the body rotates once while in this position, are used in conventional skiing. As shown, the running surface 4 from the ski tip 2 to the front snow contact point 3
Because it is smooth, it is difficult to catch the snow surface.
Furthermore, because the frictional resistance with the snow surface is small, the tip of the ski easily slips, making it difficult to perform these ``standing on tiptoe'' and ``turning on tiptoe.'' Therefore, there was a demand for skis that would allow skiers to perform these maneuvers more freely and more dynamically. In view of these conventional shortcomings, the present invention aims to provide skis for ballet skiing that make it easier to perform ``standing on tiptoe'' and ``turning on tiptoe'' in ballet skiing events, as well as allowing for more dynamic performance. It is. To explain this invention based on the drawings, as shown in FIGS. 4 to 9, it is characterized in that a protector 12 having concentric projections 11 is attached to the sliding surface of the ski tip 10. This is ski 9 for valley skiing. In the valley ski ski 9 of this invention, the concentric protrusion 11 is attached to the tip protector 1.
2, so when performing "tiptoe stand" or "tiptoe turn" performed in the ballet ski event, unlike conventional ones, the concentric protrusions 11 will surely dig into the snow surface and will not touch the snow surface. This increases the frictional resistance of the wheels, making it easier to stand on tiptoe and turn on tiptoe. To explain each embodiment of the present invention, as shown in FIGS. 6 and 8, concentric circular protrusions 1
For ballet ski skis equipped with a protector that has at least two or three concentric circles (especially when the protector is made of flexible material such as rubber), the athlete However, when the tip of the ski is pressed against the snow surface in order to simultaneously press the stock and brake the speed of the ski, the concentric projections 11 dig into the snow surface and deform at the same time. This creates a cushioning effect, which simultaneously dampens the impact while braking the ski, making skiing smoother. Furthermore, as shown in FIG. 7, by forming a notch 13 in the concentric protrusion 11, when performing a rotation performance such as a "toe turn", the snow within the concentric protrusion 11 can be removed during rotation. Since it can be discharged from this notch 13, it becomes possible to perform performances such as "turn on tiptoe" extremely easily. In addition, as shown in FIG. 9, by forming the inner protrusion of the concentric circular protrusion 11 to be taller than the external protrusion, a spike effect can be produced when controlling the speed of the ski. The effect of digging into the snow surface has been significantly improved, and the "toe turn" can be performed extremely easily, so the next performance following the "toe turn" performance can be performed more dynamically and at a high level. effective. Note that the material of the protector used in the present invention is arbitrary, such as rubber, synthetic resin, and metal.
