Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to skis, and more particularly to skis, and more particularly to skis, in which the bend can be adjusted by tensioning a string between the middle part and the head part on the top side of the ski. This invention relates to a ski that rapidly damps vibrations in the top part of the ski to enable stable skiing.

Each ski has a bend that raises the middle part above the horizontal position to help distribute the load when riding on the ski.

This bend is provided as a standard according to the length of one ski and cannot be adjusted freely, so it is inconvenient that it does not correspond to the user's weight, snow quality, slope conditions, etc.

Also, depending on the bend condition, vibrations can easily occur in the top part when skiing on hard ice, and these vibrations are difficult to dampen, resulting in a loss of skiing stability.

The present invention has been made to solve the above-mentioned problems, and its purpose is to reduce the vibration of the top part by adjusting the bend in response to external considerations such as the user's weight, snow quality, slope condition, etc. When the vehicle is rapidly attenuated and slides smoothly, it is placed between the middle part and the head part on the top side of the machine, and the elongation is controlled to a fixed length or within a certain elongation tolerance range. Another object of the present invention is to provide a ski on which a vent auxiliary material is stretched that is not regulated against shrinkage.

Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a single ski, and is formed into a normal shape.

In addition, the bend of each car is set to be large.

Reference numeral 2 denotes a support, which is fixed with screws 3 so as to stand up on the upper surface of the ski unit 1, which is slightly closer to the top than the attachment position of the binding (not shown) of the ski unit 1.

Note that this fixing means may be of any kind.

Further, a screw hole 4 is provided on the support 2.

Reference numeral 5 denotes a mounting bracket screwed onto the upper surface of the head portion 6 of the skid unit 1.

A screw rod 10 is screwed into the screw hole 4 and fixed with a nut 8, and a thread terminal 9 is screwed into the screw rod 10. 7 is a wire, one end of which is fixed to the mounting bracket 5, and the other end of which is connected to a thread terminal 9.
, and is stretched between the support 2 and the mounting bracket 5 with a certain tension.

By rotating the thread terminal 9 and moving it on the threaded rod 10, the head section 6 can be raised and lowered via the wire 7, and the top bend, especially, of the skid 1 can be freely adjusted. Get skis.

In other words, when the thread terminal 9 is moved back toward the tail of the support 2, the tension of the wire 7 becomes stronger, and the head part 6 is bent in the lifting direction, reducing the top bend and reducing the amount of snow in fresh snow or deep snow. It becomes ski suitable for. Conversely, when the thread terminal 9 is moved forward, the tension of the wire 7 becomes weaker, and the head part 6 falls down, which increases the top bend, effectively presses the top against the snow surface, absorbs vibrations from the top, and provides stability. It is possible to glide. The vibrations at the top of this ski mainly occur at high speeds, but in addition to being absorbed by the top press mentioned above, when the ski lifts off the snow surface due to a gap, etc., the bend is restored. Then, tensilan is applied to the wire 7, which suppresses the vibration.
Moreover, the effect of being attenuated is also poisonous.

Furthermore, although the wire 7 has a fixed length with respect to elongation, part or all of the wire 7 is connected to a coil spring (not shown) in order to restrict elongation within a certain allowable range.
It may be composed of

Furthermore, a rod (not shown) may be used instead of the wire. In this case, a stopper (not shown) is attached to the left end of the rod, which is slidably inserted into the support 2, so that the rear end of the rod is slidably inserted into the support 2, and the backward movement is freely restricted to the support 2, while the forward movement is restricted to a fixed position. Please provide one.

As described above, according to the ski according to the present invention, the bend can be adjusted according to the external conditions such as the weight of the skier, snow quality, slope condition, etc., and the ski can be used in an optimal condition, and the ski tip can vibrate especially at high speeds. It is possible to prevent or rapidly attenuate this, allowing stable high-speed gliding.
It has the remarkable effect of being particularly suitable as a ski for advanced skiers and for competitions.

Although the present invention has been variously explained above with reference to preferred embodiments, the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. That's true.
