Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to the structure of a ski that has excellent running stability.

<Prior Art> When looking at the cross section of skis, they are roughly rectangular in shape, and grooves called groups are carved into the bottom surface of the skis.

Therefore, once the vehicle starts skidding, no force acts to resist its movement.

For advanced riders, this gives the pleasure of meandering, but for beginners, once a sideways skid begins, the weight remains behind, and the force that pushes them sideways increases at an accelerated rate, making it easy for them to roll over. become.

OBJECT OF THE INVENTION The present invention has been made in order to improve the above-mentioned problems. The purpose of the present invention is to provide a structure, such as a ski, in which a part of a force in a direction can act as resistance.

Structure of the present invention〉〉Plate body In Fig. 1, numeral 1 is the plate of the ski, the outer periphery of the core is protected with a reinforcing material as in conventional skis, and the sliding surface is made of high-density polyethylene or the like. It is.

Depending on the purpose, groups may or may not be engraved on the bottom surface.

Kuguchi〉Pinding On the other hand, 2 is binding.

This binding 2 can also have the same structure as the conventional one.

The dough piece and heel piece of this binding 2 are both fixed on one footboard 3.

(kuha) When installing the binding, the binding 2 is not attached directly to the plate 1, but is attached via a short post 4 located between the footboard 3 and the plate 1.

The short pillar 4 is located at the center of the plate 1.

The cross-sectional area of the short pillar 4 is configured to be extremely small compared to the bottom area of the plate 1 or the bottom area of the footboard 3.

The cross-sectional shape of the short pillars 4 does not necessarily have to be square or circular, but a rectangular shape having a certain length parallel to the central axis of the plate 1 can also be used.

The attachment of the short column 4, the plate body 1, and the footplate 3 is configured so that the relative angle can be changed to some extent.

In other words, the board 1 and the tread plate 3 are not always located parallel to each other, but when a force is applied to a position away from the center of the tread board 3, the two boards 1.3 are not parallel to each other. become.

<2> Other Embodiments The case of skis has been described above, but the shoe hook 21 is placed on a wide board 1, called a surf ski, in a direction transverse to the central axis of the board 1. A similar structure can be adopted for a fixed gliding board (in the case of a ski, the binding is parallel to the gliding board). (Fig. 3.4) Other Embodiment 2 Although the above is described as a "short column" from the viewpoint of expression, it does not necessarily have to be short. For example, a groove is carved in the center of the plate 1, and the groove is Fix the lower end of the pillar material inside, and attach the upper end of the pillar material to the footboard 3.
It is also possible to use a vertically long board fixed to the bottom surface of the pillar, so to speak, and in that case the deflection of the pillar material will be even greater.

Other Example 3 The structure in which the pillars bend has been explained above, but the purpose is to place the feet on the sliding surface (as long as the relative position between the surface changes), the pillars do not bend. It is also possible to adopt a structure in which the tread is more flexible (of course, from a macroscopic perspective, it is slightly bent).

Effect of the present invention> The function of the ski of the present invention will be explained.

When the snow surface slopes to the left in FIG. 2, a force acting on the plate 1 causes it to slide from the right side to the left side, that is, from the mountain side to the valley side.

However, when the board 1 moves to the valley side, the runner's weight remains on the opposite side, and his weight is applied to the mountain side of the footboard 3.

This weight is transmitted to the plate 1 via the short columns 4, but the footboard 3, the short columns 4, and the plate 1 are not completely rigidly connected, and some deflection is allowed.

Therefore, the moment M1 that acts on the mountain side of the footboard 3 about the axis of the short pillar 4 is transmitted to the plate body 1 through the short pillar 4.
A moment M2 acts on the mountain edge 5 of the curve.

Effects of the present invention> In this way, the moment M2 acting on the edge 5 of the plate 1
serves to push the mountain side of the plate 1 into the snow.

Therefore, the edge 5 acts as a large resistance against sliding of the plate 1 toward the valley side.

Therefore, once the plate 1 starts skidding, the speed of the slide does not increase in an accelerated manner as in the conventional case, and does not increase more than a moderate amount, so only the body of the slider remains behind, and only the lower body of the slider remains sideways. There is no need to continue moving suddenly in the direction.

Moreover, it allows for a moderate amount of lateral movement, so even beginners can fully enjoy turning the ski.

Furthermore, since the mountain side of the plate 1 bites into hard surfaces such as ice burns, stable running is possible.

Moreover, since the position where the moment M1 acts is far away from the short column 4, this is different from the case where the plate body 1 and the footboard 1 are constructed as an integral structure (i.e., where the thickness of the plate body is simply increased). Therefore, a large force acts on the edge of the plate 1 on the mountain side.

The same holds true for the Swanisky shown in Figure 3.4.
