Description

[Detailed Description of the Invention] (a) Technical Field of the Invention This invention relates to ski boots, and more specifically to an improvement in the fitting mechanism that can hold the entire instep, including the upper part of the instep closer to the ankle.

(B) Prior art and problems Ski boots in recent years consist of a shell molded from hard plastic material and an inner boot that holds the foot in close contact with the shell without any gaps. In order to hold the foot well inside and improve the operability of the ski when skiing, the upper part of the shell corresponding to the ankle is tightened with a tightening mechanism, or the top of the foot is held and the ankle is tightened. This provides a more secure fit.

Conventional techniques for holding the instep of the foot to improve the ankle fit, which is important for foot-tapping, are disclosed in Japanese Patent Laid-Open No. 52-118359 and Japanese Patent Laid-Open No. 52-118360, etc. ing.

Such conventional fitting, ie, foot holding mechanism, holds the boundary between the instep and the ankle, or the middle part of the instep, from the outer surface of the inner boot using a band member.

Although this method can provide a feeling of holding the foot, since the foot-holding pressure on the foot acts intensively on a part of the instep or boundary area, the local pressure increases and may cause pain in the foot. In addition, there was a problem in that it was not possible to eliminate the play of the entire foot inside the shoe.

(c) Purpose of the invention This invention was made to solve the conventional problems as mentioned above, and it eliminates the local pressure on the foot, provides a soft holding feeling, and eliminates the play of the entire foot. It is an object of the present invention to provide a ski shoe which has a good fitting feeling and has a simplified tightening mechanism.

(d) Structure of the invention In order to achieve the above object, the ski shoes of this invention include a shell body, an inner boot inserted into the shell body, and a part formed on the shell body corresponding to the instep part. a cover member that covers the cutout opening; a presser member that is located inside the cover member and holds the boundary between the instep and the ankle from the upper surface of the inner boot; and a presser member that is connected to one end of the presser member. a band portion that is pulled out of the shell main body; a cable that is connected to the other end of the holding member and that extends over the cover member in the left-right direction and that holds the instep portion from above the cover member; It consists of a tightening buckle that is attached to the outer side of the shell main body and engages with the band portion.

(E) Example of the invention Hereinafter, an example of the invention will be described based on the drawings.

Figures 1 to 5 show an example of a ski shoe equipped with a fitting mechanism according to this invention.
is a shell body molded from a hard plastic material such as polyurethane, and this shell body 1 consists of a bottom part 2, a lower shell 3 that covers the foot part, and an upper shell 4 that covers the ankle part, and the upper shell 4 can be expanded. Its front and rear surfaces are open, and these openings are closed from the inside by a front cuff 5 and a rear cuff 6, respectively, and the lower ends of the front cuff 5 and rear cuff 6 extend in the front-rear direction. It is pivoted so that it can be tilted. Further, the portion of the lower shell 3 facing the instep of the foot has a large notch extending to the ankle, and this notch opening 7 is covered from the outside by an elastic cover member 8, and
The outer peripheral edge of the cover member 8 is engaged with the edge of the notch opening 7 in an overlapping state, and the upper edge is connected to the lower end of the front cuff 5 by a projection 9. Reference numeral 10 designates 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;
Reference numeral 1 denotes a tightening device that tightens the outer circumferences of the upper shell 4, front cuff 5, and rear cuff 6. This tightening device 11 includes a belt 11a and a belt 1
It is composed of a buckle 11b for tightly wrapping 1a. Furthermore, the forward tilt angle and forward pressure of the tightening device 11 can be adjusted by moving the tightening position relative to the upper shell 4 up and down.

Reference numeral 12 denotes a fitting mechanism for fitting the foot into the shell body 1 by holding the instep of the foot and the boundary between this and the ankle, and corresponds to the cover member 8 as shown in FIGS. 4 and 5. A pressing member 13 that is superimposed on the outer surface of the inner boot 10, and this pressing member 1.
An uneven portion 14 connected to one end of 3 and continuous to the surface.
It is composed of a belt part 14 having a shape of 1.a, a cable 15 connected to the other end of the pressing member 13, and a tightening buckle 16 fixed in a recess 3a formed on the outside of the lower shell 3 of the shell main body 1. There is. The holding member 13 holds the boundary between the instep and the ankle from the upper surface of the inner boot 10, and the belt portion 1 connected to one end thereof holds the boundary between the instep and the ankle.
4 is pulled out of the cover member 8 through the overlapping portion of the cover member 8 and the lower shell 3, is extended toward the heel portion 1a of the shell body 1, and is locked by the tightening buckle 16. At the same time, the cable 15 is inserted from the outside to the inside through a hole 17 bored at the edge of the notch opening 7 on the opposite side of the tightening buckle 16, and is further inserted through the hole 17 or the toe portion of the shell body 1. 1b and pull it outward through a hole 18 bored in the lower shell 3 in a portion close to the edge of the cover member 8, and then pull it out along the left-right groove 19 formed on the outer surface of the cover member 8. Then it was turned to Batsukuru side,
Its ends are fixed to the inner wall of the lower shell 3 by rivets 20.

In the ski boot fitting mechanism configured as described above, the belt portion 14 is attached to the buckle 16.
the ratchet claw 16a of the belt part 1.
4, and tilt the buckle 16 in the tightening direction, the pressing member 13 and the cable 15
Tension is generated in the area, and as a result, the holding member 13 and the cable 15 tighten the boundary between the instep and the ankle and the cover member 8, respectively. It is displaced from the state shown by the chain line to the state shown by the solid line, thereby holding the instep part of the foot and the boundary part connected thereto at the same time. In other words, since the instep of the foot and the boundary area connected to it are tightened as a whole, it is possible to give the foot a soft holding feeling, and there is no risk of localized pressure on the foot causing tingling, unlike in the past. This eliminates this problem, improves the fitting performance for ski boots, and eliminates play in the entire foot. Also, 1
Because the two buckles 16 can simultaneously hold the instep and the boundary part connected to the top of the foot, the fitting mechanism becomes simpler and more compact, and the protruding parts such as buckles in ski boots are reduced, making them easier to carry and ski. The risk of injury is reduced, and the ski boots themselves can be made simpler.

Furthermore, since the instep part and the boundary part connected thereto are held in its entirety, a stable feeling of fit can be obtained without increasing the tightening force as in the conventional case.

(f) Effects of the device As explained above, this device includes a holding member that holds the boundary between the instep and the ankle from the upper surface of the inner boot, and a belt portion that is connected to one end of the holding member and is secured to the buckle. and a cable that is connected to the other end of the holding member and holds the instep of the foot from above the cover member that covers this, applying fitting pressure, eliminating local fitting pressure to the foot and providing a soft hold. In addition to giving a comfortable feel, it also eliminates foot play inside the shoe. Furthermore, since one buckle can simultaneously hold the instep of the foot and the boundary between the instep and the ankle, the fitting mechanism can be simplified and made more compact.
