Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a cant adjustment device for ski boots.

[Conventional technology and its problems]

When a human foot is viewed from the front, the part below the knee is normally tilted slightly outward, and this tilt is called cant.

Since this cant varies from person to person, it is necessary to adjust the cant of the ski boot in order to fit the ski boot to each skier's feet.

Therefore, an object of the present invention is to enable the cant of ski boots to be easily adjusted.

[Means for solving problems]

The measures taken by this invention are as follows.

That is, a pressing plate that presses the outer wall surface of the inner boot is inserted between the inner wall surface of the outer shell above the inner ankle and the outer wall surface of the inner boot, and a screw hole is drilled in the upper part of the inner ankle of the outer shell.
A screw shaft was screwed and inserted into this screw hole, and the end of this screw shaft was rotatably supported by the pressing plate.

[Effect]

When the screw shaft is rotated, the screw shaft engages with a screw hole formed in the outer shell and moves back and forth. This allows the pressing plate to move toward and away from the outer shell. Therefore, for people with a large cant, the pressure plate can be moved away from the outer shell, that is, by moving the pressure plate from the inside of the boot toward the outside, while for people with a small cant, By moving the pressure plate closer to the outer shell, that is, by moving the pressure plate from the outside to the inside of the ski boot, the foot above the ankle can be tightly fitted into the ski boot.

〔Example〕

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

The ski boot 1 consists of an outer shell 2 and an inner boot 3. The outer shell 2 is made of semi-hard or hard synthetic resin.
In addition, the inner boots 3 provide close contact and padding functions to the skier's feet, and have a built-in foam material and a surface finished with artificial leather or the like.

The outer shell 2 is composed of three members: a shell body 4 that covers the area below the ankle, a front cuff 5 that covers the area from the ankle to the calf, and a rear cuff 6 that covers the area from the heel to the calf. Both lower ends of the front cuff 5 and rear cuff 6 are rotatably attached to shafts provided at side points 7 below both the inner and outer ankles of the shell body 4, respectively. A stepped portion 8 is formed in the upper part of the front side of the ankle of the above shell body 4 from both sides to the upper surface, and when the front cuff 5 rotates forward about the side point 7, the lower front end of the front cuff 5 is formed. The edge abuts against the stepped portion 8 to prevent the front cuff 5 from rotating further forward. On the rear side of the front cuff 5,
Buckles 9 and 10 are provided above and below to integrally connect the front cuff 5 and the rear cuff 6.

A pressing plate 11 for pressing the outer wall surface of the inner boot 3 is inserted between the inner wall surface of the outer shell 2 and the outer wall surface of the inner boot 3 above the inner ankle of the ski boot 1. The pressing plate 11 has a substantially rectangular shape and is made of semi-hard or hard synthetic resin.

Through holes 12 and 13 are formed in the front cuff 5 corresponding to positions near both the upper and lower ends of the press plate 11, and female screw members 14 are fitted into the through holes 12 and 13, respectively. A female thread is formed at the lower part of the inner peripheral surface of this female thread member 14. A screw shaft 15 is threadedly inserted into this female threaded member 14 . A support plate 1 is attached to the end of this screw shaft 15.
6 is attached, and this support plate 16 is rotatably supported by a holder 17 provided on the surface of the press plate 11.

Next, the operation of this embodiment will be explained.

When the screw shaft 15 is rotated, the screw shaft 15 engages with the female thread member 14 and the female thread, and moves forward and backward. As a result, the press plate 11 rotatably supported at the end of the screw shaft 15 via the support plate 16 and the holder 17 moves toward and away from the inner wall surface of the front cuff 5.

Therefore, for people with a large cant, by moving the pressing plate 11 away from the side of the front cuff 5, that is, by moving the pressing plate 11 from the inside of the ski boot 1 toward the outside, the cant can be reduced. For small people, by moving the pressure plate 11 closer to the side of the front cuff 5, that is, by moving the pressure plate 11 from the outside of the ski boot toward the inside, the foot above the ankle can be fitted snugly into the ski boot. can be done. Further, since the press plate 11 is provided with screw shafts 15 at two locations, upper and lower, by changing the amount of advance and retreat of the screw shafts 15 at the upper and lower locations with respect to the female thread member 14, the inclination angle of the press plate 11 can be adjusted. It can be changed. This results in
The pressing plate 11 fits snugly against the side of the foot.

〔effect〕

As described above, the present invention can be easily achieved by moving the pressing plate inserted between the inner wall surface of the outer shell above the inner ankle of the ski boot and the outer wall surface of the inner boot using the screw shaft. This has the effect of being able to perform cant adjustment.

In addition, if the cant adjustment is made by tilting the front cuff and rear cuff with respect to the shell body, there is a drawback that the front cuff and rear cuff themselves rotate toward the inside of the top of the ski when leaning forward, and the front cuff Another disadvantage is that there is a gap in the overlapping portion of the rear cuff and the shell body. However, according to the present invention, the cant adjustment is performed using the pressure plate provided inside the ski boot without inclining the front cuff and rear cuff themselves, so the front cuff and rear cuff themselves are always at the top of the ski. It also has the effect that there is no gap between the overlapping portions of the front cuff and rear cuff and the shell body.
