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.
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 skis that are commercially available as skis exclusively for the valley ski event have only a wider side cut shape than before, 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 The techniques include a ``tiptoe stand,'' in which the skier presses the ski against the snow surface and uses the tip 8 of the ski as a fulcrum to perform a handstand, and a ``toestand turn,'' in which the rider turns the body once while in this state. There are, but
In conventional skis, as shown in Fig. 2, the sliding surface 4 from the ski tip 2 to the front snow contact point 3 is smooth, making it difficult to catch the snow surface and causing frictional resistance with the snow surface. They were small and the tips of the skis could easily slip, making it difficult to perform ``stand on tiptoe'' or ``turn 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.

To explain this invention based on the drawings, as shown in FIGS. 4 to 9, a flat part 11 and a stepped part 12 are formed on the sliding surface of the ski tip 10 in a stepped, fish scale, etc. This ski 9 for valley skiing is characterized by being provided with a snow surface resistance portion 13 having an arbitrary shape.

The snow surface resistance portion 13 may be molded separately and then bonded to the surface of the sliding surface, or may be molded integrally with the sliding surface plate.

As described above, this device is provided with a snow surface resistance section 13 that forms a flat section 11 and a stepped section 12 on the sliding surface of the ski tip section 10, so it is suitable for "tiptoe" and "tiptoe" movements in valley skiing events. When performing a "turn" maneuver, the snow surface resistance section 13 digs into the snow surface, and the stepped portion 12 increases the frictional resistance with the snow surface, making it easy to perform a "stand on tiptoe" maneuver. Furthermore, when performing a "turn on tiptoe", the snow that has bitten into the snow surface resistance section 13 is pushed out along the flat section 11 and step section 12 in the direction opposite to the rotational direction, making it easier to perform a "turn on tiptoe". . “Standing on tiptoe” like this
If it becomes easier to perform the "turn on tiptoe," the transition from this performance to the next, and even more dynamic performance, will become smoother. Further, the material of the snow surface resistance section 13 is arbitrary, but since the snow surface resistance section is formed with a flat section 11 and a step section 12, it suppresses vibrations at the tip of the ski and has a vibration damping effect. , which improves the glide and maneuverability of skis.
