Description

[Detailed Description of the Invention] The present invention relates to an improvement to valet skis used in freestyle skiing.

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.
Although short skis are used in this event of valley skiing, until now there have not been many skis specifically for this event on the market, so competitors have had to choose short skis or junior skis that suit them. This is what is currently being used. In addition, some commercially available skis exclusively for the valley ski event only have side cut widths wider than conventional skis, and no new improvements have been made specifically for the valley ski 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 it against the snow surface, using the tip 8 of the ski as a fulcrum,
Strategies such as ``toe stand,'' where you do a handstand, and ``toe turn,'' where you rotate your body once in this state, have been incorporated, but in conventional skiing, the tip of the ski is Since the sliding surface 4 from part 2 to front snow contact point 3 is smooth,
It was difficult to catch the snow surface, and the frictional resistance against the snow surface was small, causing the tip of the ski to easily slip, making it difficult to perform ``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 drawbacks, 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 something.

The present invention will be explained based on the drawings. As shown in FIGS. 4 to 6, the present invention is characterized in that an arbitrary uneven shape 13 is formed on the sliding surface 12 from the ski tip 10 to the front snow contact point 11. This is ski 9 for valley skiing.

As described above, in the valley skiing ski 9 of the present invention, the arbitrary uneven shape 13 is formed on the sliding surface 12 from the ski tip 10 to the front snow contact point 11, so that the "toe standing" performed in the valley ski event is performed.
When performing a "turn on tiptoe" or "turn on tiptoe", unlike conventional ones, this uneven part digs into the snow surface and increases the frictional resistance with the snow surface, so "standing on tiptoe" or "turn on tiptoe" becomes very difficult. Since it is easy to perform, it is possible to use these performances as a springboard to perform even more dynamic performances. In addition, in the valley ski ski of the present invention, the running surface from the tip of the ski to the point of snow contact has an arbitrary uneven shape, so the uneven shape absorbs the vibrations generated at the tip of the ski. Therefore, a volleyball ski with good vibration damping properties can be provided.

In the drawings showing the embodiment of the present invention, the tip of the ski is cut off, but other than this shape, a conventional ski with a protruding tip can be used with the same effect.

In other embodiments of the present invention, shallow intersecting grooves or small protrusions or protrusions may be formed on the sliding surface.
