Description

[Detailed description of the invention] (a) Technical field of the invention This invention relates to ski boots, and in particular to ski boots equipped with a cant adjustment mechanism that corrects the unbalanced load on skis due to X-legs and O-legs. be.

(b) Prior art and problems Human legs are not completely perpendicular to the horizontal plane, but are inclined outward or inward around the knees. That is, the skeleton of the legs is O-legged or X-legged, although this varies depending on individual differences. In this case, there is no problem with normal walking or exercise, but when it comes to skiing, the tilting of the O-legs or X-legs outward or inward causes the load on the skis to be unbalanced from side to side, making it difficult to perform accurate edge operations. As well as becoming unable to
This will increase leg fatigue.

Therefore, ski boots have been equipped with a cant mechanism that balances the left and right loads on the ski even if the leg is tilted laterally.
This type of technology is already known in Japanese Patent Application Laid-Open No. 14439/1983.

The above-mentioned conventional ski boots have a plurality of push-up devices on the sole facing the lower surface of the insole provided on the inside of the sole, and by individually operating the push-up devices up and down, the insole is pushed up against the sole surface of the shoe. The edging operation is made easier by tilting it at an arbitrary angle to correct the lateral inclination with respect to the O-leg or the X-leg.

However, there are problems as described below.

In other words, since the push-up device is composed of screws,
A tool is required for the operation, and in order to satisfy occasional adjustment requests on the slopes, the user must carry the tool with him, making it troublesome to carry and manage the tool. Additionally, when adjusting the insole's inclination, multiple push-up screws must be operated individually, which takes time. In addition, adjustments must be made while considering the balance of each push-up screw, which makes the adjustment process even more time consuming. It gets complicated. Furthermore, the push-up screw is exposed from the bottom surface of the shoe sole, and the threaded gap communicates with the inside of the shoe sole, so there is a risk that moisture may infiltrate into the shoe through this threaded gap, and dirt and moisture may adhere to the screw surface. There was a problem that the screws could become oxidized and the screws could no longer be operated.

(C) Purpose of the invention This invention was made in order to solve the above-mentioned conventional problems. To provide ski shoes which ensure waterproofness and eliminate malfunction.

(d) Structure of the invention In order to achieve the above object, the ski shoes of this invention include a shell main body, an inner boot inserted into the shell main body, and an inner boot that penetrates vertically through the center of the heel of the shell main body. A cant adjustment body that is rotatably and watertightly fitted into the formed cylindrical hole, has an end face cam on the upper end face protruding into the shell body for correcting the lateral inclination of the leg, and has a knob on the lower end. and,
a heel member rotatably holding the cant adjustment body within the cylindrical hole; a heel member disposed within the bottom of the shell main body and located on the lower surface of the inner boot;
and a support plate that is elastically deformed by the end cam of the cant adjustment body to change the heel installation surface in accordance with the lateral inclination of the leg.

(e) Examples of the invention Examples of the invention will be described below with reference to drawings.

Figures 1 to 6 show an example of a ski boot equipped with a cant adjustment mechanism according to this invention, in which 1 is a shell body molded from a rigid plastic material such as polyurethane;
The shoe consists of a sole 2, a lower shell 3 that covers the skier's foot, and an upper shell 4 that covers both left and right sides of the ankle. Further, the front and rear openings of the upper shell 4 are closed from the inside by a front cuff 5 and a rear cuff 6, as shown in FIG. The lower end of each is pivotally connected to the lower shell 3 as shown in FIG.

7 is an inner boot molded from a flexible material that is interposed between the shell body 1 and the skier's feet in order to fit the skier's feet within the shell body 1; This tightening device is capable of tightening the outer circumferences of the front cuff 5 and rear cuff 6, and at the same time setting the forward tilting angle and forward tilting pressure of the boot. The band main body 8a to be stopped and its tightening buckle 8b
It is composed of.

9 is a cant adjustment mechanism that equalizes the load on the skis on the left and right sides by correcting the degree of lateral inclination caused by the outward or inward inclination of the legs associated with O-legs and X-legs to almost zero. 7, a flexible support plate 10 having a size corresponding to the area from the arch of the foot to the lower surface of the heel, and a cant adjustment body 11 that deforms the heel corresponding portion of the support plate 10 according to the skeletal condition of the leg. It is configured.

The support body 10 has three pillars 12 protruding from the lower surface facing the arch of the inner boot 7.
(see FIG. 5), and the lower surface of each support column 12 is engaged with a U-shaped engagement portion 13 formed on the inner surface of the bottom portion 2, thereby holding the support plate 10 within the bottom portion 2. In addition, circular notches 14 are formed at opposing positions in the central part of the arch.

The cant adjustment body 11 has a cylindrical shape as shown in FIG. 6, and is provided with an end cam 15 at its upper end for correcting the inclination outward or inward with respect to the horizontal plane due to O-legs and X-legs, and has a knob at its lower end. 16 is formed, a flange 17 is formed on the outer circumferential surface on the lower side, and a plurality of convex portions 18 are formed on the outer circumferential surface on the lower end side.

As shown in FIG. 2, the cant adjustment body 11 thus constructed is fitted into a cylindrical hole 19 formed at the center of the heel portion of the lower shell 3 by penetrating it vertically, and is attached to the lower surface of the heel by a screw 20. By holding the flange 17 with the fixed heel member 21, the cant adjustment body 11 can be rotated relative to the cylindrical hole 19, and an O-ring 25 is inserted between the upper end surface of the flange 17 and the step portion 19a that engages with it. Further, the inner peripheral surface of the cylindrical portion 19 is formed with recesses 22 that each of the projections 18 engages with, and the projections 18 and the recesses 22 allow the cant adjustment body 11 to be moved freely. rotation is now regulated. Further, on the periphery of the hole 21a of the heel member 21 that exposes the knob 16 of the cant adjustment body 11, a cant adjustment scale 23 is engraved over a range of approximately 180 degrees as shown in FIG. An instruction mark 24 corresponding to 23 is formed on the knob 16.

Next, the cant adjustment operation of this embodiment configured as described above will be explained.

First, when there is almost no lateral inclination of the leg with respect to the horizontal plane and no cant adjustment is required, the indicator mark 24 of the knob 16 is positioned at the center of the cant adjustment scale 23 as shown in FIG. For this reason, the upward lead surface 1 of the end cam 15 of the cant adjustment body 11
5a engages with the rear edge 10a of the support plate 10, and the portion of the support plate 10 corresponding to the heel is symmetrical as shown in FIG.

On the other hand, if the cant adjustment body 11 is rotated such that the knob 16 is rotated in the direction of arrow A in FIG. The lead surface 15a engages with the inner edge 10b of the support plate 10, thereby elastically deforming the inner edge 10b of the support plate 10 upward as shown in FIG. Make the inside slope higher than the outside. As a result, the heel installation surface is adapted to a bow-legged skier who leans outward with respect to the horizontal plane. In other words, when a bow-legged skier covers ski boots that have been adjusted in cant in this manner, the load pressure applied to the skis will be balanced between the left and right sides.

On the other hand, when the cant adjustment body 11 is rotated such that the knob 16 is rotated in the direction of arrow B in FIG. Upward lead surface 15
a engages with the outer edge 10c of the support plate 10, thereby elastically deforming the outer edge 10c upward as shown in FIG. Make it slope. Therefore, the heel installation surface is suitable for skiers with X-legs who lean inward with respect to the horizontal plane. In other words, if a skier with X-legs wears ski boots with the cant adjusted in this way, the load pressure on the left and right sides of the skis will be balanced, allowing for accurate edge control, and reducing stress and fatigue on the feet. The degree of this can be reduced.

The degree of leg correction can be adjusted using the cant adjustment body 11.
This is done by changing the upward lead surface 15a of the end cam 15.

(F) Effect of the device As explained above, according to this device, a cylindrical hole is formed in the heel of the shell body, penetrating vertically, and inside this cylindrical hole, the outer or inner side of the O-leg and the X-leg are formed on the upper end surface. A cant adjusting body formed with an end cam for correcting the inclination in the lateral direction of the leg is rotatably and watertightly fitted, and the bottom of the shell body is elastically deformed by the end cam of the cant adjusting body. , and because it is equipped with a support plate that changes the heel installation surface according to the inclination of the leg outward and inward, it is possible to adjust the cant to suit the skeleton of the leg using only the cant adjustment body and manual rotation. Therefore, there is no need for a conventional adjustment tool, and since it is only necessary to rotate the cant adjustment body in a predetermined direction, the complexity and complexity of adjustment are eliminated, and the adjustment is easy and practical. In addition, the fitting part of the cant adjustment body with the cylindrical hole can be easily sealed with a sealing material such as an O-ring, making the sole of the shoe completely waterproof.
Since the cant adjustment body only rotates and does not move up and down, there are advantages such as no dirt entering or adhering to the fitting portion and no malfunction.
