Abstract

PROBLEM TO BE SOLVED: To properly hold an inner boot and a foot in a pressed state inside the arch of the foot by applying the constitution that a holding member with one end fixed to the sole center part and the other end extended so as to cover an area from the fixed part to the instep part, can be tightened and held by connecting the other end to a tightener. SOLUTION: Regarding a ski boot formed out of an outer shell and an inner boot 4 mounted inside the outer shell, a holding member 7 is provided for pressing and holding the outer side part of the inner boot 4 over an area from the outer side of the foot to the instep zone thereof. Furthermore, the buckle part 83b of a tightener 8 connected to one end 73 of the holding member 7 is turned to cause a locking fixture 83c to be engaged with an engagement piece 81. Thereafter, the buckle part 83b is turned, thereby pulling the engagement piece 81 via the locking fixture 83c and pulling the holding member 7 in an elongation direction. The inner boot 7 is thereby tightened and held internally. In this case, the adjustment of a tightening and holding force is made by selectively engaging the locking fixture 83c to other locking grooves of the engagement piece 81.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ski shoe in which inner boots are mounted in an outer shell, and to a ski shoe in which the play of a foot inserted in the inner boot is eliminated to improve ski operability. .

[0002]

2. Description of the Related Art Recent ski shoes have an outer shell formed of a rigid plastic material such as polyurethane.
It is composed of inner boots mounted inside the outer shell in order to keep the feet in close contact with each other without gaps.

In such a ski boot in which inner boots are provided in the outer shell, there is a ski boot in which the arch portion of the foot can be pressed and adjusted.
-106303. Further, Japanese Patent Laid-Open No. 47-7829 discloses a technique for fitting the inner boot and the foot by injecting a forming liquid into the inner boot and curing the same along the foot mold.

Usually, a small space is created in the region from the arch part to the instep part in the ski boot, and this space weakens the transmission of the force when the ski is turned and causes a slow reaction speed. There is. However, the above-mentioned JP-A-3-
With the configuration disclosed in No. 106303,
There is a drawback that the force escapes laterally. Also,
The structure disclosed in Japanese Patent Application Laid-Open No. 47-7829 has a drawback that once the foot shape is adjusted, the adjustment cannot be performed after the fact, and the shape cannot be changed according to the improvement of the technique.

In order to correct the above-mentioned drawbacks, the applicant of the present invention, as disclosed in Japanese Patent Application Laid-Open No. 7-108002, holds the inner side portion of the inner boot by pressing and holding it from the arch to the instep region. It was previously proposed that a holding member is attached and the holding force of the holding member can be adjusted from the outside.

[0006]

However, in the case of the structure disclosed in Japanese Patent Laid-Open No. 7-108002, the foot can be surely held in the inner boot without a gap, but the inner shell has the outer shell. Since there is still a space left between the inner boot and the inner boot, even if the rigidity of the inner side surface of the outer shell is increased, the holding member bends, so the rigidity at the turn is low, and further improvement in ski operability is required. Has structural limitations.

The present invention has been proposed in view of the above-mentioned problems of the prior art. In the inside, there is no gap between the outer shell and the inner boot so that the bending of the holding member occurs at the time of turning. Therefore, it is an object of the present invention to provide a ski shoe that can maintain a high sense of rigidity of the outer shell, increase a sense of stability, and improve ski operability.

[0008]

In order to achieve the above object, the present invention provides a ski boot having an inner boot in an outer shell, one end of which is fixed to a substantially central portion of the bottom in the front-rear direction and the other end of which is fixed. It is characterized in that it has a holding member extending so as to pass through the outside of the foot and covers the instep, and the other end of the holding member is connected to a tightening tool to hold the holding member in a tightened state.

FIG. 3 is a side perspective view, FIG. 3 is a plan perspective view, and FIG. 4 is a sectional view of a portion corresponding to the instep. In the following description, this ski boot for the right foot will be used for description.

As shown in FIGS. 1 to 4, a ski shoe 1 according to a first embodiment of the present invention is an outer shell 3 formed of a hard and tough synthetic resin, and a skier mounted in the outer shell 3. The inner boot 4 is made of a flexible foam rubber or the like that fits the foot.

The outer shell 3 mainly comprises a shell main body 30 which covers a lower part of the ankle, a trunk 31 which integrally covers the lower part of the ankle and the lower part of the calf to hold the ankle, and a shoe which constitutes a shoe sole. It is composed of the bottom portion 33. The lower end of the body portion 31 is attached to the shell body 30 by a connecting member 35 so as to be tiltable in the front-rear direction so that the body portion 31 can be tilted according to the forward tilting posture of the skier.

In the upper region of the shell body 30, as can be seen from FIG. 4, a split polymerization portion 36 is formed which is divided right and left from the upper opening of the shell body 30 and overlaps with each other. Buckles 5 for the upper part that straddle the divided overlapping portion 36 to clamp and hold the upper part are provided at two positions in the front and rear at predetermined intervals. Further, although not shown in the drawing, a similar divided overlapping portion is formed on the front side of the body portion 31. An ankle buckle 6 for tightening and holding the ankle portion so as to straddle the divided overlapping portion also on the body portion 31.
Are provided in two places, upper and lower.

As can be seen from FIG. 4, the inner space 30a of the shell body 30 of the outer shell 3 is integrally connected to the inner space 33a of the shoe sole 33 so as to be in communication with each other.
An insole foot vent 37 is accommodated in the inner space 33a of No. 3, and the upper surface of the foot vent 37 is flush with the inner wall surface defining the inner space 33a of the shell body 30. The inner boot 4 is placed and held on the foot vent 37.

In the present invention, in addition to the basic structure of the ski boot as described above, a holding member 7 for pressing and holding the outer side portion of the inner boot is provided from the outer surface side of the foot to the instep region. ing. One end 71 of the holding member 7 is fixedly attached to the outer upper surface portion of the foot vent 37 with a screw 77. Then, the other end 73 of the holding member 7
Is passed between the shell body 30 of the outer shell 3 and the inner boot 4 and is on the instep side (upper side) of the shell body 30.
It is led out to the outside of the shell body 30 from the opening 30a formed in the.

The other end 73 of the holding member 7 is connected to the tightening tool 8 for tightening the holding member. This tightening tool 8 has the same structure as that of the buckles 5 and 6, and has a holding member 7
An engaging element 81 having a locking groove fixedly attached to the other end side 73 of the above, and a tightening tool main body 83 fixedly attached to the outside of the shell main body 30. Fastener body 83
Is composed of a buckle portion 83b rotatably attached to the fixed portion 83a and a locking metal fitting 83c attached to the buckle portion 83b and engaged with the engaging groove of the engaging element 81.

That is, when the buckle portion 83b is rotated in the direction of arrow A to engage the locking metal fitting 83c with the engaging element 81, and then the buckle portion 83b is rotated in the direction of arrow B,
The locking metal piece 83c pulls the engaging element 81, and the holding member 7 is pulled in the extension direction to hold the inner boot 4 tightly inside. In addition, adjustment of this tightening retention force is
This is performed by selectively engaging the locking metal piece 83c with another locking groove of the engaging element 81. The tightening tool 8 is not limited to the illustrated one, and its specific structure, shape, etc. are not particularly limited as long as the tightening force can be adjusted.

The material of the above-mentioned holding member 7 may be synthetic resin, leather, cloth or the like, but it is required that it has a high strength against a tensile force. Further, although the case where the screw 77 is used as the method of fixing the one end side 71 of the holding member 7 has been described, the present embodiment is not limited to this, and is fixed by rivets, fixing with a reinforced adhesive, or sewing. It may be a fixing method. The specific shape of the holding member 7 is not limited to the illustrated one. Further, the fixing place of the one end side 71 of the holding member 7 is not limited to the one shown in the figure, and it may be fixed near the central portion or further inward, that is, near the arch.

In the first embodiment described above, the tightening tool 8 of the holding member 7 is provided independently, but in the second embodiment, as shown in FIG. The buckle 5 for tightening the upper part also serves as the tightening tool 8.

That is, of the two instep buckles 5,
The engagement fitting 55 connected to the buckle portion 53 of the buckle 5 on the toe side is engaged with the engagement groove of the engagement element 81 attached to the other end side of the holding member 7.

[0021]

As described above, according to the ski boot of the present invention, since the holding member is tightened, the inner boot and the foot contained therein are securely held in a pressed state on the inside of the arch side. As a result, the holding member does not bend at the time of turn, the original sense of rigidity of the ski boot is kept high, the sense of stability at the time of turn is increased, and the downhill operability is improved. Moreover, since the tightening force of the holding member in the present invention has a structure similar to that of the buckle, even if the swelling of the foot or the thickness of the sock is changed, the locking position is simply changed. The tightening force can be adjusted easily.
