Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ski tool suitable for correcting the position of the sliding surface of the ski, that is, the edge position when the ski is mounted.

[0002]

2. Description of the Related Art When mounting a ski, a binding (fastener or ski fitting) is used to fix the ski boot to the ski. Generally, the binding is basically composed of a heel binding for fixing the heel side of a ski shoe and a toe binding for fixing the toe side. Heel bindings and toe bindings come in various forms, such as those that are separately fixed to the skis at predetermined intervals according to the size of the ski shoe, or those that are integrally connected by a connecting member. It has been commercialized. As for the method of attaching the binding to the ski, when attaching the binding directly to the ski,
In some cases, a mount having a constant thickness may be interposed between the ski and the binding.

By the way, in order to freely slide on a snow surface, it is necessary to freely change the sliding direction of the ski. This change of direction is called a turn, but this turn can only be made by operating the edge of the ski. The edge that contributes to the turn is basically the inner edge (the arch side of the foot), and skiing skill depends on whether the operation to raise the left and right inner edges against the snow surface can be switched quickly and smoothly. The bad guys are decided. This edge switching is associated with a weight shifting operation for the left and right skis.

Regarding how to apply weight to the ski,
Although there are various modes depending on individual differences in the skeletal structure of the human body, generally, it is often the case that the so-called X-leg structure makes it difficult to master edge operations.

That is, in the case of X-legs, although the weight in a natural walking posture or a standing posture depends on the inner side of the foot (the arch side of the foot), it is appropriately adjusted by the joints of the ankles, so it does not cause much problem. I won't.

However, when a skier puts on a ski through ski shoes and a binding, and takes a gliding posture with his knee and ankle attached to each other,
The weight is applied to the outside of the foot, and the inner edges of the left and right skis are floated by about 2 to 10 mm relative to the outer edges. In other words, the bottom surface of the left and right skis when viewed in a cross section in the transverse direction of the ski has a V shape, and the outer edge is depressed (or digs) into the snow surface by that amount, which is substantially The outer edge will work.

[0007]

As described above, in order to smoothly and swiftly turn, the left and right inner edges must be quickly switched.

However, if the conventional ski shoes, bindings, and skis are left as they are, the skeleton structure of the human body is created by forcibly fixing the ankles by the ski shoes and maintaining the parallelism between the back surface of the foot and the skiing surface. The resulting angle relationship between the back of the foot and the lower limbs is directly reflected on the skiing surface of the ski, and when the skiing posture is taken with the knee and ankle attached to each other, the inner edges of the left and right skis as described above. Will be in the shape of a V that floats about 2 to 10 mm relative to the outer edge.

In this state, it takes a lot of time to move the weight applied to the outer edge to the inner edge side located in the opposite direction, and moreover, the sliding surface of the ski slips during the switching of the edges. A condition occurs that is parallel to the snow surface, which is equivalent to the condition that there is no working edge required for the turn, and therefore the skis flow laterally at this time, which results in weight transfer to the inner edge. Something that cannot be done smoothly happens. This tendency is especially common among beginners.
Further, this causes a time loss due to the lateral slippage of the ski even for a competitor competing for the running time.

Therefore, an object of the present invention is to provide a ski device which can easily and surely perform edge switching regardless of individual differences in the skeletal structure of the human body.

[0011]

According to a first aspect of the present invention, the ski is arranged so that the position on the back surface of the foot corresponding to the inner edge side of the ski is relatively higher than the position corresponding to the outer edge side. A straightening device for fixing the shoe to the ski is provided.

A second aspect of the present invention is characterized in that, in the first aspect, the straightening device is capable of adjusting a relative height.

According to a third aspect of the present invention, in the first aspect, the correction device is provided on a ski or a ski boot.

According to the invention, the straightening device is such that the position on the underside of the foot corresponding to the inner edge side of the ski is relatively higher than the position corresponding to the outer edge side, in other words the transverse direction of the ski. Since the inner edge side of the ski shoe is formed thicker than the outer edge side as seen in the cross section, even if the bottom surface of the ski shoe has an inclination that sinks to the outer edge side, it does not work as an inner edge on the skiing surface. The outer edges can be kept parallel. Keeping the inner edge parallel to the outer edge is a new operation for turning the edge.
The neutral position is maintained, and this neutral position is nothing but the position that keeps the ski surface close to the inner edge. Therefore, according to the ski equipment of the present invention, it is possible to switch to the inner edge quickly and smoothly, and it is possible to overcome the individual differences in the skeleton of the human body, promote the acquisition of ski skills for beginners, and suppress the time loss of athletes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings.

(I) First Embodiment In FIG. 1, reference numeral 5 indicates a ski for the left foot,
The tip of the ski 5 is in the direction of the arrow.
A correction device 1 is provided on the ski 5. The straightening device 1 has an adjusting plate 3 and a binding mounting plate 7, and the adjusting plate 3 and the binding mounting plate 7 are fixed to the ski 5 by screws 9. This fixed position is
It is a predetermined position that is preset on the ski 5,
It is located near the center of the length of the ski 5.

The upper surface of the adjusting plate 3 is inclined so that the position on the inner edge 5a side of the ski boot is relatively higher than the position on the outer edge 5b side. The inclination angle of the adjusting plate 3 can be adjusted by exchanging it with an adjusting plate having an inclination angle different from that of the adjusting plate 3. In order to replace the adjusting plate 3, it is only necessary to remove the screw 9 and replace it with another adjusting plate 3. A binding (not shown) is attached to the binding attachment plate 7, and a ski shoe (not shown) is attached to this binding.

Next, the operation of the first embodiment will be described. When a skier normally stands on a snow surface with ski shoes, bindings, and skis, the skeleton of the human body
The weight is applied to the outside to some extent, the outer edge 5b is pushed downward, the inner edge 5a floats, and the outer edge sinks. On the other hand, when the skier turns on the slope during downhill, the inner edge 5a is usually used for skiing while keeping the knees and ankles close to each other or sticking them to each other. The weight on 5b is moved to the inner edge 5a side. Regarding this point, in the conventional one, when the weight shifts from the outer edge 5b to the inner edge 5a, the ski 5 becomes almost parallel to the running surface instantaneously, so the ski 5 slips and flows at that moment. In some cases, the weight cannot be properly moved to the inner edge 5a side, and the player cannot turn well.

However, if the straightening device 1 is provided and the inner edge 5a side of the ski boot is raised as in the present embodiment, the skier attaches the ski boot, the binding, and the ski to the skiing posture on the snow surface. When taken, the ski 5 can be maintained parallel to the snow surface regardless of the inclination of the ski shoe, so that the weight of the skier can be moved to the inner edge 5a side in a short time, and therefore the ski 5 when turning is turned. It is possible to prevent the lateral displacement of In addition, the left and right balance is easily maintained and the ski operation is easy, so even beginners can easily turn.

The inclination angle of the adjusting plate 3 of the straightening device 1 can be adjusted according to the skier's technical stage. The larger the angle of inclination, the greater the contact of the inner edge 5a with the snow surface at the time of turn, resulting in a sharp turn with no lateral deviation. For example, a beginner may select an adjusting plate having an inclination angle such that both skis are parallel to the snow surface or the weight is applied slightly inward when the skis stand up. Then, after that, the tilt angle may be increased according to the improvement of the technique, or an adjusting plate having the tilt angle suitable for the purpose may be appropriately selected.

Thus, the adjusting plate 3 selected according to the skier's technical stage and purpose is placed at the above-mentioned predetermined position on the ski 5, and the upper screw 9 on which the binding mounting plate 7 is superposed as described above. Mounted by.
