Abstract

PURPOSE: To provide a feeling integrated with a foot regardless of the type thereof by dividing an instep zone into right and left sections from the notch of a shell body for forming a divisional superposed section, and fixing a plate for covering the notch to one side of the shell body in such a state as striding across the notch. CONSTITUTION: An outer shell 27 has a shell body 31 to cover a section lower than an ankle, and the body 31 is provided with an approximately U-shaped notch 45 over a range from the upper opening of the body 31 to a bent section 43 adjacent to an instep zone. Also, a section ranging from the notch 45 to the instep zone is divided into right and left sections, thereby forming a divisional superposed section 41. The notch 45 is covered with a plate 51 and only one side thereof is fixed to the inner side of the body 31 with two screws in such a state as striding across the notch 45. According to this construction, a foot can be inserted and pulled out pertinently, and a ski boot 25 as a whole provides a rigid feeling. In addition, a feeling integrated with a foot can be provided, regardless of a foot type.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front entry type ski boot.

[0002]

2. Description of the Related Art Recent ski boots are composed of an outer shell formed of a hard and tough synthetic resin such as polyurethane, and an inner boot mounted inside the outer shell to keep the foot in close contact with each other. There is. Then, in order to hold the foot and improve ski operability, conventionally,
In front-entry ski boots, the bending part and the upper part region are divided into left and right parts from the front part of the body forming the outer shell and the upper opening of the shell body to form a divided overlapping part (lap part), and each divided part The tightening device attached to the overlapping part is tightened to create a sense of unity between the foot and the ski boot. Then, the tightening device is released, and the split overlapping portion of the body and the shell body is opened to the left and right so that the foot can be taken in and out.

However, as described above, the outer shell is made of a hard synthetic resin for the purpose of preventing the escape of force due to the lateral strain at the time of leaning forward. It was pointed out that it was difficult. Therefore, in order to improve the putting in and out of the feet, Japanese Patent Laid-Open No. 4-907
In the publication No. 01, as shown in FIGS. 7 and 8, the upper portion of the divided overlapping portion 3 of the shell body 1 divided left and right from the upper opening to the instep region is cut out from the bent portion 5, and this cut is made. A ski shoe 11 in which an overlap belt 9 covering the cutout portion 7 is provided separately from the shell body 1 is disclosed.

As shown in FIG. 8, the overlap belt 9 is formed into a shape that wraps around the instep region of the shell body 1, and its edge portions 9a and 9b are vertically overlapped with each other to form the overlap belt. The second buckle 13 attached to 9 is used for tightening. And
Both end portions of the overlap belt 9 are extended to the ankle portion and are axially supported together with the shell body 1 and the body portion 15.
The upper portion of the overlap belt 9 is covered with the body portion 15,
The ankle portion of the inner boot 22 is tightened together with the body portion 15 by operating the third and fourth buckles 19 and 21 attached to the division overlapping portion 17 of the body portion 15.

Thus, according to such a ski shoe 11, the buckle 13, 19 of the overlap belt 9 and the trunk portion 15 together with the first buckle 23 mounted on the shell body 1 are provided.
When 21 is released and the overlap belt 9 and the trunk portion 15 are opened, the bending portion 5 of the shell main body 1 is greatly cut out, so that it is easy to put the foot into the shell main body 1.

[0006]

However, in the ski shoe 11 described above, when the second buckle 13 is tightened,
When the entire overlap belt 9 is deformed and the ankle portion of the inner boot 22 is tightened, and when the third buckle 19 on the body portion 15 side is tightened, the entire overlap belt 9 is similarly deformed and the upper part of the shell body 1 is similarly deformed. It has been pointed out that it has the drawback of tightening the area.

Therefore, for example, when a person with a high instep and a thin ankle operates the third buckle 19 to properly tighten the ankle, the overlap belt 9 is deformed and the instep of the foot becomes tight. The second buckle 13
Even if the upper part of the foot is properly tightened by operating, the tightening of the ankle part is insufficient, so if the third buckle 19 is operated to tighten the ankle part, the overlap belt 9 is deformed and the upper part of the foot is deformed. The part is tightened further and becomes tight.

Similarly, when a person with a thick ankle and a low instep operates the second buckle 13 to properly tighten the instep, the overlap belt 9 is deformed and the ankle becomes tight. Even if the third buckle 19 is operated to properly tighten the ankle, the second belt 13 is operated to tighten the upper part because the upper part of the foot is not sufficiently tightened. The ankle will be tightened further and it will be tight.

Further, in the above-mentioned conventional example, it is pointed out that slippage occurs between the shell body 1 and the overlap belt 9 at the time of leaning forward, so that the ski boot 11 lacks in rigidity. . The present invention has been devised in view of such circumstances, and provides a ski shoe in which the feet can be put in and out satisfactorily and the overall feeling of rigidity can be achieved, and yet a feeling of unity with the feet can be achieved in response to any foot type. The purpose is to do.

[0010]

In order to achieve such an object, the invention according to claim 1 provides a tightening device at a front portion of an outer shell which is composed of a shell body and a body portion tiltably attached to the shell body. In the mounted front entry type ski boot, the shell body is provided with a cutout portion extending from the upper opening to the bent portion with the instep region, and the instep region is divided into left and right parts from the cutout portion. Then, a plate is formed so as to form a divided overlapping portion, and a plate covering the cutout portion is fixed to one side of the shell main body with the cutout portion interposed therebetween.

[0011]

According to the ski boot according to the first aspect, when the tightening of each tightening device is released to open the divided overlapping portion of the body, the notch provided in the upper opening of the shell body opens largely. Becomes Since the plate is fixed to one side of the shell body only on one side, it does not hinder the putting in and out of the foot.

Further, in order to insert the foot into the inner boot and tighten the inner boot, after covering the cutout portion with the plate, the dividing overlapping portion of the body portion and the dividing overlapping portion of the shell body are respectively attached by the respective tightening devices. Just tighten it. And, even if the tightening device of the shell body is tightened, the plate is not affected by that and does not tighten the ankle part of the inner boot.
Further, when the tightening device on the body side is tightened, the plate does not tighten even the divided overlapping part of the shell body even if the ankle part of the inner boot is tightened.

Further, the plate prevents the entry of snow or water from the cutout portion.

[0014]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 shows an embodiment of a ski shoe according to claim 1. The ski shoe 25 includes an outer shell 27 formed of a hard and tough synthetic resin such as polyurethane, and an outer shell 27 mounted in the outer shell 27. The inner boot 29 is formed of a flexible foam rubber or the like that fits the foot.

Then, as in the conventional case, the outer shell 27
Is a shell body 31 that mainly covers the lower part from the ankle,
It consists of a trunk 33 that integrally covers the lower shin and lower calf of the ankle, and the lower end of the trunk 33 is pinned to the ankle portion of the shell body 31 so that it can be tilted forward depending on the forward tilting posture of the skier. It is attached at 35. Further, the front surface portion of the body portion 33 is divided into left and right portions and overlapped with each other, and the divided overlapping portion 3 is formed.
5 is formed, and the body portion 33 can be tightened by operating the third buckle 37 and the fourth buckle 39 provided at two positions above and below the division overlapping portion 35.

Similarly, in the upper region of the shell body 31,
A split overlapping portion 41 is formed which is divided into left and right portions and overlaps with each other, but the shell body 31 has a substantially U-shaped shape extending from its upper opening to a bent portion 43 in the instep region as shown in FIG. The cutout portion 45 is provided, and the cutout portion 45 is provided.
The instep region is divided into left and right parts to form the above-mentioned divided overlapping part 41.

Then, the shell body 3 is operated by operating the first buckle 47 and the second buckle 49 attached to the dividing and overlapping section 41.
The upper region of No. 1 is tightened, but as a result of providing the notch portion 45 from the upper opening of the shell body 31 to the bent portion 43 in this way, even if the second buckle 39 is tightened, the shell The upper portion of the main body 31 does not strongly tighten the ankle portion of the inner boot 29.

Further, in FIG. 2, reference numeral 51 denotes a plate which covers the cutout portion 45 to prevent snow and water from entering, and is formed of a synthetic resin softer than the shell body 31. Thus, the plate 51 is fixed to the inner side of the shell body 31 with two screws 53 only on one side 51a side with the notch portion 45 interposed therebetween, and the lower side 51b is fixed to the second buckle 49. It is molded to a size that does not cost.

Therefore, even if the second buckle 49 is tightened in the direction of the arrow A in FIG. 3, the plate 51 does not tighten the ankle portion of the inner boot 29 due to the influence thereof, and the third buckle 37 is used. 4 is tightened in the direction of arrow B as shown in FIG. 4, the sliding direction of the plate 51 and the tightening direction of the third buckle 37 coincide, so that the plate 51 tightens the ankle portion of the inner boot 29, but the plate 51 does not Even the divided overlapping portion 41 of 31 is not tightened.

Since the ski shoe 25 according to the present embodiment is constructed in this way, the buckles 37, 39, 47, 4
When the tightening by 9 is released and the divided overlapping portion 35 of the body portion 33 is opened, the notch portion 45 provided in the upper opening of the shell body 31 is opened greatly. Further, as described above, the plate 51 is fixed to the shell main body 31 only on one side 51a side thereof, so that there is no problem in putting in and out of the foot.

Further, in order to insert the foot into the inner boot 29 and tighten it, after covering the notch portion 51 with the plate 51, the division overlapping portion 35 of the body portion 33 and the division overlapping portion 41 of the shell body 31 are attached. , Buckles 37, 39, 4 respectively
Tighten with 7,49. Even if the second buckle 49 is tightened in the direction of arrow A as shown in FIG. 3 as described above, the plate 51 does not tighten the ankle portion of the inner boot 29 under the influence of the tightening operation, and the third buckle. When 37 is tightened in the direction of arrow B as shown in FIG. 4, the plate 51 does not tighten the split overlapping portion 41 of the shell body 31 even if the ankle portion of the inner boot 29 is tightened.

Therefore, for example, a person with a high instep and a thin ankle operates the first and second buckles 47 and 49 to appropriately tighten the divided overlapping portion 41 of the shell body 31, and
Even if the third and fourth buckles 37 and 39 are operated to appropriately tighten the split overlapping portion 35 of the body portion 33, the split overlapping portion 41 of the shell body 31 is not further tightened by the plate 51.

Further, the plate 51 prevents snow and water from entering through the cutout portion 45. Therefore, according to the present embodiment, the foot can be put in and taken out well, and the second buckle 49 and the third buckle
Since the range of tightening with the buckle 37 is divided, it is possible to achieve a sense of unity with the foot corresponding to any type of foot, and furthermore,
The buckles 37, 39, 47, 49 are fixed to the body 33 and the shell body 31, and there is no slippage unlike the shell body 1 and the overlap belt 9 of FIG. There is no lack of overall rigidity.

In addition, according to this embodiment, the plate 51
It is also possible to adjust the strength of the forward lean by changing the material. Although the one side 51a of the plate 51 is fixed to the inside of the shell main body 31 with the screw 53 in the above-described embodiment, the tightening effect of the plate 51 is reduced. Only the shell body 31
May be fixed to the outside of the shell with a screw 53. Alternatively, instead of fixing with the screw 53, one side 51a of the plate 51 is attached to the inside of the shell body 31 with an adhesive 55 as shown in FIG. May be.

Furthermore, as shown in FIG. 6, the plate 5
It is also possible to provide a tongue piece 57 in the direction of the second buckle 49 on the one side 51a 'side of 1'and fix the tongue piece 57 with a rivet for fixing the second buckle 49. Thus, according to each of these embodiments, the intended purpose can be achieved as in the case of the above embodiment.

[0026]

As described above, according to the ski shoe of the first aspect, the legs can be put in and out well, and the entire ski shoe has a sense of rigidity. It has an advantage that a sense of unity can be achieved. Further, according to the present invention, the forward inclination strength can be adjusted by changing the material of the plate.
