Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ski shoe having an outer shell and an inner boot inserted into the outer shell.
In particular, the present invention relates to ski boots that can reliably prevent the front cuff from tilting backwards.

[Conventional technology]

Modern ski boots are mainly constructed with a synthetic resin outer shell and an inner boot that is inserted into the outer shell. A pressure adjustment mechanism has been added, and the rear cuff, which covers the area from the heel to the calf, can be opened and closed in the front and rear directions.

The forward tilt pressure of the forward tilt pressure adjustment mechanism increases as the forward tilt angle of the front cuff with respect to the vertical line of the ski boot increases. In other words, when a skier receives an external force by leaning forward or bending the knees,
The forward inclination angle of the ankle part of the shoe, including the front cuff, changes, which improves the maneuverability of the ski without putting undue strain on the skier's legs, and improves stability during skiing, shock absorption, and ease of edging. I'm trying to get it.

Conventionally, as ski boots equipped with the above-mentioned forward tilt pressure adjustment mechanism, those shown in Japanese Patent Application Laid-Open No. 59-225001 and Japanese Patent Application Laid-Open No. 61-8682 are known.

[Problem that the invention attempts to solve]

As mentioned above, conventional ski boots focus on improving the comfort and safety of the skier's shoes and the operability of the skis by changing the forward tilt pressure according to the increase or decrease of external force applied to the front cuff. Although various improvements have been made in this regard, at present little consideration has been given to reliably preventing the ankle portion of the ski boot from tilting backwards.

For example, as disclosed in Japanese Unexamined Patent Publication No. 59-225001, the lower end of the front cuff is fixed to the shell body at two places on the front and back with rivets, or the lower end of the front cuff is fixed to the shell body with a single rivet. It is attached so that it can be tilted forward, and a stepped portion that engages with each other is provided at the front part of the ankle where the shell body and the front cuff overlap, and this stepped portion is used to prevent the front cuff from tilting backward. However, in the former method in which the two lower ends of the front cuff are fixed with rivets, the part extending to one of the rivets is made of an elastically deformable material that deforms as the front cuff tilts forward.
It does not function very well in preventing the ankle part of the ski boot from tilting backwards.

In addition, the step shown in the latter method is mainly intended to prevent snow and water from entering the shell, and for this reason, when performing various ski operations such as bending and stretching the knee, the stepped portion of the shoe ankle When a backward tilting force is applied to the shell, the overlapping portion between the front cuff and the shell main body will be greatly deformed, and the backward tilting will become large, and the prevention function cannot be expected. This caused the problem of unstable ski operation.

[Purpose of invention]

The present invention has been made to solve the above-mentioned problems, and its purpose is to provide a ski boot that reliably prevents the ankle from tilting backwards and allows stable skiing operations.

[Means for solving problems]

The ski boots according to the present invention consist of an outer shell and an inner boot inserted into the outer shell, and the outer shell is attached to a shell body, a front cuff attached to the shell body so as to be tiltable forward, and a front cuff attached to the shell body so as to be tiltable backwards. In the ski boot, a stopper for preventing backward tilting is provided on the side surface of the shell main body, with which the rear edge of the front cuff abuts.

[Effect of invention]

In this invention, when the front cuff receives a backward tilting force, its rear edge immediately collides with the stopper, so that the ankle part of the shoe can surely tilt backwards without deforming the front cuff etc. It becomes possible to prevent it.

[Example of idea]

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 show an example of a ski boot according to the present invention.

In FIG. 1, a ski boot indicated by the general reference numeral 1 is roughly divided into an outer shell 2 molded from a hard and tough synthetic resin material, and an inner boot 3 inserted into the outer shell 2. There is.

The outer shell 2 consists of a shell body 4 that mainly covers the area below the ankle, a front cuff 5 that covers the area from the ankle to the shin, and a rear cuff 6 that covers the area from the upper heel to the calf of the foot. The lower end of the shell body 4 is the medial and medial ankle portion 4
The lower end of the rear cuff 6 is pivotally connected to the heel cover portion 4b of the shell body 4 by a pivot pin 8 so that it can be tilted forward. . Further, on the inner and outer heel portions 4a of the shell main body 4, as shown in FIG. 1 and FIG. The stopper 9 is formed in a stepped shape and prevents the ankle portion of the ski boot including the front cuff 5, that is, the rear cuff 6, from tilting rearward. Further, 10 is a tightening device that tightens and connects the front cuff 5 and the rear cuff 6 together, and 11
is an anterior tilting pressure adjusting device for the front cuff 5.

In the ski boots of this embodiment configured as described above, when the front cuff 5 and the rear cuff 6 receive a backward tilting force according to the movement of the skier's legs during skiing operations such as when skiing, the solid line in FIG. The lower end edge 5a of the front cuff 5 immediately abuts against the stopper 9, thereby preventing the front cuff from tilting backward. The maximum tilting angle at this time is α shown in FIG. 1, and the tilting angle is never greater than this tilting angle α. Therefore, the rearward tilting of the shoe neck part is reliably prevented, the front cuff 5 and the shell body 4 are not deformed as in the conventional case, and the insertion of the foot into the ski boot is stabilized. , stable ski operation becomes possible and ski operation becomes easier.

FIG. 3 is a side view of the main parts of another embodiment of the ski shoe according to the present invention. In the same figure, the first
The difference from the drawing is that a stopper 9A for preventing tilting is formed of a separate member such as metal from the shell body 4, and this stopper 9A is integrally fixed to the ankle portion 4a of the shell body 4 with a rivet 12 or the like.

In this embodiment as well, the same effects as in the above embodiment can be obtained.

It is preferable that the stoppers for preventing rearward tilting be provided on both the inner and outer sides of the shell main body 4, but they may be provided on one side. Alternatively, it may be formed by inserting metal, ceramic, or the like into the shell body 4.

[Effect of idea]

As described above, according to the present invention, a stopper that prevents the front cuff from tilting backward is provided on the side of the shell body, and by abutting the front cuff against this stopper, the front cuff is prevented from tilting backward. Therefore, it is possible to reliably prevent the ankle part of the shoe from tilting backwards without deforming the front cuff or shell body, and this makes it possible to stably insert the ski boot onto the foot, making it easy and stable to ski. Operation becomes possible.
