PURPOSE: To evenly tighten ski shoes even with one piece of buckle and to enable fine adjustment as well by providing a recessed part formed in an upper cover with a slit, fitting the ladder of the buckle into this recessed part, successively passing a wire fitted at an upper shell into the curving part of a wire and a wire retainer and connecting this wire to the pin in the lower part of the ladder. CONSTITUTION: The recessed part 51 of the upper cover 5 is internally provided with the slit 52 and the ladder 31 constituting the buckle 3 is slidably fitted into this recessed part. The wire 33 for tightening and loosening extending from a tightening and loosening means 32 mounted onto the upper shell 12 is hooked to the projecting part of the ladder 31 and the tightening and loosening means 32 is tightened finely adjustably. The wire 7 is successively passed through the curved part 71 of the wire, the wire retainer 72 and the curved part 73 of the wire and is connected to the pin 311 in the lower part of the ladder 31. Consequently, the two points are tightened by means of the buckle 3 with equal force. The wire 33 for tightening and loosening disengages from the projecting part of the ladder 31 when the tightening and loosening means 32 is kicked up at the time of inserting and removing the foot.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ski boot tightening device.

[0002]

2. Description of the Related Art A front buckle type ski boot is shown in FIG.
As shown in, the instep and the rising part of the outer shoe excluding the toe part of the outer shoe are incised in the longitudinal direction, and wing pieces B are formed on the left and right sides of the incision.
2 is provided so that the wing pieces B2 are overlapped with each other, and further, the buckle B1 is attached to the left and right wing pieces B2, and the overlapping degree (tightening degree) of the wing pieces B2 is adjusted by loosening the buckle B1. It was intended to correspond to the foot shapes of different wearers. The number of buckles B1 for adjusting the overlapping condition (tightening condition) of the wing pieces B2 is generally four in total, two in the instep part and two in the rising part.

However, it is quite possible to tighten and loosen four buckles with one foot and a total of eight buckles with both feet while adjusting the tightening condition to correspond to the shape of the wearer's foot in a cold ski area. It was a tedious task. Also, since the buckle is exposed to the outside, the buckle was an air resistance in the competition for speed such as downhill and large rotation.

Therefore, as one of the countermeasures, efforts have been made to reduce the number of buckles, but if the number of buckles is reduced, the degree of overlap (tightness) of the left and right wings of ski shoes can be finely adjusted. Instead, the ski shoes would not fit well. Figure 7 shows the wire C3
It is a ski shoe in which the number of buckles is reduced to three by using. To describe the structure in detail, the wire C3 axially attached to one end of the instep C5 changes its direction by 180 degrees at the wire bending portion C4 provided at the other end across the center line of the shoe, and again the center line of the shoe. Is connected to the buckle C1. The rising portion of the ski shoe is a buckle C2 similar to the conventional one.

In the tightening / loosening device used for the upper part of the ski boot shown in FIG. 7, the upper part is tightened with a buckle C1. When the buckle C1 is moved in the tightening direction, the wire C3 that traverses the instep twice is one continuous wire, so that the two parts of the instep can be tightened with the same force. Therefore, unlike the case where two buckles are provided on the instep as shown in FIG. 6, one buckle can tighten two insteps with the same force according to the preference of the wearer. is there.

On the other hand, one wire C3 passing through two insteps is used.
From the place where you tighten with the buckle C1, buckle C
The movement range of 1 becomes large. Therefore, when the buckle C1 is fully tightened (pulled), the buckle C1 comes extremely close to the snow surface, and in the worst case, the buckle C1 may come into contact with the snow surface at the time of turning, which may hinder skiing. Further, when inserting / removing the foot into / from the ski boot, unless the wire C3 is removed from the wire bending portion C4, the instep shell does not spread and the foot is hard to insert / remove. There was also the drawback that it had to be removed from C4.

[0007]

Therefore, according to the present invention, the instep can be tightened and loosened with one buckle, and the instep can be tightened with an even force even with one buckle, and the tightening can be finely adjusted. Is also trying to be able to.
In addition, the buckle is less likely to become air resistance, and when tightening the buckle, the buckle does not come into contact with the snow surface and interferes with ski skiing. It is intended to provide a device.

[0008]

To this end, the present invention provides a buckle 3 including a wire 7 pivotally attached to one end of an instep shell 12, a ladder 31, a fastening wire 33, and a fastening tool 32. The upper cover 5 has one end pivotally attached to the upper shell 12 62. The upper cover 5 is provided with a recess 51, and the recess 51 is provided with a slit 52. The ladder 31 forming the buckle 3 is provided with the recess 51. The wire 7 slidably fitted inside, and the pin 311 at the lower part of the ladder 31 is projected from the slit 52 of the recess 51, and the shaft 7 is axially attached 61 to one end of the instep shell 12, the instep center line A The upper portion tightening device of the ski shoe is formed by passing through the wire bending portion 71, the wire retainer 72, and the wire bending portion 73, which are provided on the other end in this order, and connecting to the pin 311 below the ladder 31.

Further, a wire threading part 53 is attached to the instep cover 5, and the wire threading part 53 and the ladder 3 are attached.
A spring 74 is interposed between the lower pin 1 and the pin 311 to allow the wire 7 to pass through the wire 53 through the through hole 531.
It may be connected to the pin 311 at the bottom of the ladder 31 through the center of the spring 74.

[0010]

When the instep tightening device of the present invention is used, the degree of tightening of the instep can be adjusted by simply tightening / unfastening the tightening / loosening tool 32 of one buckle 3. That is, the upper part of the ski boot is the wire 7
However, the instep part is crossed over from the place where the shaft attachment 61 is crossed over the instep part centerline A to the wire bent part 71 at the other end, and between the wire bent part 73 and the ladder 31 forming the buckle 3 at the instep part. It will be tightened. Moreover, since the wire 7 for fastening the two places is connected to the buckle 3 by one, the two places can be fastened by the buckle 3 with equal force.

The components such as the wire 7, the wire bent portion 71, the wire retainer 72, and the wire bent portion 73 are hidden under the upper cover 5, and the ladder 31 forming the buckle 3 is also the recess 51 of the upper cover. The air resistance is extremely low because it is fitted to. The tightening degree of the instep can be finely adjusted by the position when the tightening / releasing wire 33 extending from the tightening / loosening tool 32 is hung on the convex portion of the ladder 31. And the fastener 32 is fixed on the upper shell 12,
Only the ladder 31 moves even when the wire 7 is tightened (pulled), and the tightening / loosening device 32 does not move in the snow surface direction, so that the ski surface may come into contact with and hinder skiing. There is no such thing.

When the fastening / loosening tool 32 is flipped up at the time of inserting / removing the foot, the fastening / loosening wire 33 comes off from the convex portion of the ladder 31,
The ladder 31 is provided with a fastener 32 in the recess 51 on the upper cover 5.
Slide in the opposite direction. As a result, the wire 7 connected to the ladder 31 is loosened, so that it is easy to insert and remove the foot. Moreover, since the wire 7 is pressed by the wire presser 72, even if the wire 7 is loosened, the wire bent portions 71, 7
It does not deviate from 3. Furthermore, if the spring 74 is interposed between the wire threading part 53 and the pin 311 below the ladder 31, and the wire 7 is passed through the center of the spring 74, the ladder 31 will always use the force of the spring 74 to maintain the upper cover 5. Since the upper concave portion 51 is pushed toward the fastening tool 32 side, the fastening wire 33 is easily hooked on the convex portion of the ladder 31.

Further, since the instep cover 5 is connected to the wire 7 through the wire threading part 53, it does not move in the vertical direction. Therefore, the upper cover 5 does not float above the upper shell 12, and the rate of snow intrusion through the gap between the upper cover 5 and the upper shell 12 is reduced.
Further, when inserting / removing the foot, if the tightening / releasing wire 33 is removed from the convex portion of the ladder 31, the instep cover 5 moves up and down to some extent, so that the insertion / removal of the foot is not hindered. .

[0014]

FIG. 1 is an example of a ski shoe embodying the present invention. In this ski shoe, an instep portion and an upstanding portion of the outer shoe excluding the toe portion are incised in the longitudinal direction, and the incision is made at this incision portion. Tongue 4
Is provided. The present invention uses not only the ski boot of this embodiment, but also a tongue 4 in which the upper part of the outer shoe excluding the upper toe part and the rising part are incised in the longitudinal direction, and wing pieces are provided on the left and right sides thereof. It is also possible to implement it on a ski boot like that of FIG.

In FIG. 1, the upper cover 5 is pivotally mounted 62 on the upper shell 12 of the ski boot, and the recess 51 of the upper cover 5 is provided.
A ladder 31 is slidably fitted inside. A fastening wire 32 extending from a fastening tool 32 mounted on the upper shell 12 is hooked on the convex portion of the ladder 31 to tighten the fastening tool 32. When inserting / removing the foot, when the fastening / loosening tool 32 is flipped up, the fastening / loosening wire 33 is disengaged from the convex portion of the ladder 31, and the ladder 31 slides in the concave portion 51 to the side opposite to the fastening / fastening tool 32. Move. Since the wire 7 is connected to the ladder 31, the wire 7 loosens as the ladder 31 slides. Therefore, it is possible to insert and remove the foot. The buckle 3 attached to the cuff 2 may be the same as a conventionally known buckle.

FIG. 2 is a plan view of the upper portion of the ski boot of FIG. 1 as seen from directly above. The upper portion cover 5 is removed and its position is shown by a dotted line. The wire 7 is pivotally attached 61 to one end of the upper shell 12. Wire 7 is the center line A of the instep
The wire bending portion 71, the wire retainer 72, and the wire bending portion 73 provided on the other end of the ladder 31 are sequentially passed and connected to the pin 311 below the ladder 31.

In the present embodiment, the wire bending portions 71, 73
Has a shape in which the upper shell 12 is provided with a convex portion. The wire 7 is caught on this convex portion, and the direction of the wire 7 is changed by 90 degrees. Wire presser 72
Prevents the wire 7 from coming off the wire bent portions 71 and 73 when the wire 7 is loosened.
The structure of the wire bending portion is not limited to this embodiment, and although not shown, for example, the instep shell 12 is not provided with any convex portion, a longer wire retainer 72 is attached, and the end of the wire retainer 72 is attached. Alternatively, the wire bent portions 71 and 73 may be used.

FIG. 3 is a plan view of the instep cover 5. The dotted line in the figure shows the positional relationship when the instep cover 5 is attached to the instep shell 12. A recess 51 is provided in the instep cover 5, and a slit 52 is formed in the recess 51. Further, the upper cover 5 is pivotally attached 62 to the upper shell 12, but is slightly movable in the vertical direction so that the upper shell 12 can easily spread when the foot is inserted or removed.

FIG. 4 shows an upper shell 1 of a ski shoe according to the present invention.
2 is a cross-sectional view taken along the line including the recess 51 of the instep cover 5 in FIG. In the recess 51 of the instep shell 5, the ladder 31
Are slidably fitted together. In this embodiment, the ladder 3
A pin 311 is projected from the lower part of No. 1, and a pullout prevention tool wider than the width of the slit 52 is attached and fitted to the tip of this pin 311. Also, at the tip of this pin 311,
The wire 7 is connected. A plurality of protrusions are provided on the upper surface of the ladder 31 so that the fastening wire 33 can be hooked. The ladder 31 is slidable in the recess 51, and the ladder 31 slides to generate the ladder 3.
The wire 7 connected to 1 is tightened or loosened.

A wire threading part 53 having a hole 531 through which the wire 7 passes as shown in FIG.
Is attached. And wire passing parts 5
3, a spring 74 is interposed between the pin 311 at the bottom of the ladder 31 and the wire 7 through which the wire 7 passes.
After passing through the through hole 531, the center of the spring 74 is passed and is connected to the pin 311 at the lower portion of the ladder 31. By doing so, the ladder 31 is always pushed by the spring 74 and slides the concave portion 51 toward the tightening / loosening tool 32 side (right side in the drawing). Therefore, the tightening / releasing wire 33 is hooked on the convex portion of the ladder 31. It will be easier. Further, when the foot is inserted and removed, the spring 74 contracts and the ladder 31 slides in the recess 51 to the side opposite to the fastener 32 (left side in the drawing). You can insert and remove your feet without any problems.

Further, a wire threading part 53 is connected to the instep cover 5, and the through hole 5 of the wire threading part 53 is connected.
Since the wire 7 is passed through the wire 31, and the wire 7 is fixed by the wire retainer 72 and the wire bending portion 73 so as not to move in the vertical direction, the upper cover 5 eventually moves in the vertical direction. There is no. Therefore, as shown in FIG. 3, it is possible to prevent the upper cover 5 from floating above the upper shell 12 simply by axially attaching 62 the front side of the upper cover 5 onto the upper shell 12; The rate at which snow enters through the gap between the upper shell 12 and the upper shell 12 decreases. Further, when inserting / removing the foot, by removing the tightening / releasing wire 33 from the convex portion of the ladder 31, the instep cover 5 moves up and down to some extent, which may prevent the insertion / removal of the foot. Absent.

[0022]

When the instep tightening device of the present invention is used, it is possible to tighten the two insteps with an equal force by simply tightening / loosening the single fastener 32. Further, since the components other than the fastening / loosening tool 32 and the fastening / loosening wire 33 are hidden under the instep cover 5 or only slightly project from the instep cover, the air resistance becomes extremely small. The degree of tightening of the instep can be finely adjusted by the position when the fastening / loosening wire 33 is hung on the convex portion of the ladder 31.
Since it is fixed on the wire 2, the tightening device 32 does not move in the snow surface direction even if the wire 7 is tightened, and there is no possibility that it will come into contact with the snow surface and hinder skiing.

When inserting / removing the foot, the wire 7 is a ladder 3
Since 1 is loosened by sliding in the recess 51, it is easy to insert and remove. Moreover, the wire 7 is pressed by the wire presser 72 and does not come off from the wire bent portions 71 and 73. The spring 74 between the wire threading part 53 and the pin 311 below the ladder 31 pushes the ladder 31 toward the tightening / loosening tool 32 side, so that the tightening / releasing wire 33 is easily hooked on the convex portion of the ladder 31. Since the wire passing parts 53 are connected to the wires 7, the upper cover 5 does not float above the upper shell 12, so that the rate of snow entering through the gap is also reduced.
