Description

[Detailed Description of the Invention] Field of Application This invention relates to a device for fixing skis with the bottom side facing up in order to care for the surface of the ski that comes into contact with the snow (hereinafter referred to as the bottom side).

Prior Art In ski competitions, it is necessary to always apply wax to the bottom of the ski and carefully finish it. For this reason, the skis are fixed to the stand with their bottoms facing up, but conventionally the skis have been held by holding the skis in a vise style on both ends of the skis. However, in recent years skis have become thinner and thinner, making it no longer possible to hold them in place using this method.

Also, in recent years, trapizoid skis have been created in which both sides of the ski are sloped in a trapezoidal manner, but this type of ski cannot be held with conventional vice-type clamps. Therefore, it is considered that the top surface can be used to attract and fix the product.
If you tried to fix it using an elastic suction cup, it would be unstable and the ski would come off if you applied a strong force to it. Therefore, suction has been attempted using a vacuum pump, but the disadvantage is that the device is large, heavy, expensive, and difficult to handle.

Solution of the Present Invention In order to overcome the drawbacks of the prior art, the present invention uses a simple mechanism to surround the suction cup with a ring whose position is adjustable, thereby stably supporting the ski.

Embodiment In FIG. 1, the lower part is a clamp 1 for attaching this device to a fixed base, and a screw shaft 2 is fixed to this. A suction cup 5 made of elastic plastic is fixed upwardly on the top of the screw shaft 2. Further, the shaft 2 is provided with a nut 3 which is inserted into the shaft 2, and a cup 4 is provided on the nut 3 which is guided by the shaft 2 and can freely move up and down. The upper outer circumference of the cup 4 constitutes a support ring 6 that rests against the surface of the ski 7 when the cup is raised.

Function When the clamp 1 is fixed to the stand and the nut 3 is lowered (the state shown in Fig. 1), the cup 4 is lowered. Then, turn the bottom of the ski 7 up and press it firmly onto the suction cup 5. Next, rotate the nut 3 by hand to push up the cup 4 to the state shown in FIG. At this time, the entire circumference of the suction cup 5 is in close contact with the ski, and the ski is attached to the support ring 6 on the upper surface of the cup 4.
held on top. Two units of this device are attached to a stand, on which skis are stably fixed.

As shown in FIG. 3, a convex suction cup holding protrusion 8 is provided on the upper inner surface of the cup 4, and as the cup rises, the support ring 6 comes into contact with the ski 7, and the holding protrusion 8 can also be used to ensure suction by pressing the ``heel'' part of the suction cup against the ski.

In addition, since cleaning the skis involves sharpening the ski edges, it is convenient to install a vice for holding the skis vertically in parallel with this device. FIG. 4 shows this, and 9 is its vice.

Effects In this invention, the suction cup provides the force that attracts the ski, and the support ring 6 on the top of the cup maintains the ski in a stable position, so even if a strong external force is applied, the support ring will not absorb it. Skis can be securely fixed. Also, since the ski does not tilt or get twisted relative to the suction cup, the suction cup does not come off.
