Description

[Detailed Description of the Invention] A. Purpose of the Invention A. Field of Industrial Application The present application seeks to provide a ski suitable for propeller-propelled power ski equipment or sleds, front skis of snowmobiles, and the like.

B. Conventional technology and its problems Simply attaching a board to a conventional ski, such as the above-mentioned power ski, has little effect on preventing falls when turning in fresh snow (deep snow). Particularly in high-speed sharp turns, the car leans significantly outwards, which leaves me feeling uneasy.

Skis do not flex when driving through gears. Also, a large amount of force is concentrated at the contact point between the plate and the ski, making this area prone to damage.

When the skis are stationary and change direction, the skis get stuck in the snow because there is no sled in the rear part.
Requiring more force than necessary, and applying excessive force, will result in damage to the ski and ski mounting hardware.

Even if a ski is simply equipped with a horizontal plate, the horizontal plate always acts as a resistance to slipping into the snow even when going straight.

B. Structure of the invention A. Means for solving the problem The present application attempts to solve the above-mentioned problem with the following structure. That is, the auxiliary plate 3 is connected to the connecting protrusion 2A provided on the outside of the ski body 2 in the longitudinal direction of the ski body, and the sliding surface 2 of the ski body 2 is
The connecting portion between B and the sliding surface 3A of the auxiliary plate 3 is configured to have a rounded shape, and the top 2C of the ski body 2 has a shape that, when the ski body is viewed from the front,
This ski is constructed so that the auxiliary plate 3 is hidden.

1 is the proposed ski. Therefore, the structure is such that an auxiliary plate 3 is connected to the connecting protrusion 2A provided on the ski body 2 on the outside of the ski body 2 in the longitudinal direction of the ski body, and the auxiliary plate 3 is connected to the sliding surface 2B of the ski body 2. The connecting portion of the auxiliary plate 3 with the sliding surface 3A is configured to be rounded, and the auxiliary plate 3 is configured to fit within the width of the top 2C of the ski body 2, leaving the outer upper side of the auxiliary plate 3. ing. In addition, the outer ridgeline portion 2 connected to the sliding surface 2B of the ski body 2
B' is configured to be R. Inner ridgeline portion 3 connected to the sliding surface 3A of the auxiliary plate 3
A' is configured to be a radius R' that matches the radius R above. Reference numerals 4 and 5 indicate notches formed between the ski main body 2 and the auxiliary plate 3 in the front and rear directions around the connecting protrusion 2A between the two. The rear sliding surface 2D of the ski body is curved upward.

C. How to use the skis of this application can be attached to skis for propeller-propelled power skis, or attached to runners for deep snow sleds.

C. Effects of the Idea By making the outside edge of the ski (excluding the top part) and the outside plate rounded from the running surface, it is possible to more effectively prevent the ski from leaning outward during sharp turns at high speeds. Therefore, since the distance between both skis can be made narrower, it becomes possible to travel through forests. This also eliminates the fear of falling while driving.

By providing a cut between the ski and the plate, the elasticity of the ski is not impaired, and the plate can be prevented from being damaged or peeled off when running in the gears.

By deflecting the tail of the huski, it is easier to reverse direction or change direction when stationary, and prevent damage to the ski attachment parts.

Performance is further improved by making the Niski top section large enough to prevent the outer plate from sinking into the snow and creating resistance when driving in a straight line.
