Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ski that is easy to rotate and improves rotation speed, and its structure will be described in detail as follows with reference to the accompanying drawings.

A predetermined inner width of the ground-contact bottom surface of the ski 1 is formed as a horizontal surface, and the remaining outer width is formed as an inclined surface whose outer edge is separated from the extension line of the horizontal surface. The slope gradually becomes gentler toward the rear end.

Furthermore, a sliding groove 2 is formed in the central longitudinal direction of the inner horizontal surface.

To explain the things in the drawing, C is where you put your feet on.
- The C line sectional view part has an inclination that is 3 mm away from the ground line, the B-B sectional view area in front of this position has an inclination that has a separation length of 2 mm from the ground line, and the A-A line The cross-sectional view part has an inclination that is 1 mm away from the ground line, and the D-D cross-sectional view part behind the C-C line cross-sectional view is 2.5 mm from the ground line.
The inclination is such that the distance is 2 mm from the ground line.

A sliding groove 2 is formed in the central longitudinal direction of the inner horizontal surface to improve straight sliding.

An intermediate edge 3 is provided at the boundary between the horizontal surface and the inclined surface.

If this intermediate edge 3 is provided, there will be three edges 3 when the left and right ends are combined, so that good braking can be achieved.

The inventor noticed that in slalom races, the records of racers who raise snow clouds were worse than those of racers who did not raise snow clouds, and thought that a ski that could minimize the resistance during rotation would be a ski suitable for slalom races. Thus, the present invention was completed.

In other words, he realized that when turning, only the edge resistance was needed on the inside of the ski, which is the trough, and anything else would just give unnecessary resistance, so he formed the inside width of the ski to a horizontal plane of a normal ski. ,
The remaining outer width is formed into an inclined surface to minimize the ground contact area to about 1/2 compared to conventional skis.
By setting it to around 2, unnecessary resistance will not be applied to the bottom of the ski.

Moreover, since this wide slope is formed over the entire length of the ski, it becomes a ski with even less resistance.

At this time, it is better not to hit the outside edge of the mountain foot, and if the edge of the mountain foot hits, you will often fall.

Especially for children, the load remains on the mountain ski instead of applying it to the valley ski, and if the outside edge of the mountain ski hits, it can cause the child to stumble and fall.

In such a case, according to the present invention, the outer side of the mountain ski is an inclined surface, and the outer edge will not get caught, so there will be no unnecessary resistance and there will be no fall.

Therefore, the ski becomes easy to turn and exhibits excellent performance as a ski for racers in slalom competitions.

In addition, this ski for children can be advertised as a ski that does not fall over when turning, and the slope is also formed gradually from the front end to the rear end, based on the position where the ski feet are placed. There are almost no steps formed at the boundary between the horizontal part of the bottom of the ski and the sloped surface, resulting in a ski that makes stable contact with the ground and has an excellent appearance.Also, since this sloped surface is straight, it is easy to process. In addition, it has excellent features such as being able to ground stably even when touching an inclined surface.
