JPH04138101A - Forward inclination power adjusting device for ski shoe - Google Patents

Abstract

PURPOSE:To make forward inclination power adjustment of a ski shoe by simple handling by moving an adjusting block left and right so as to bring it in contact with receiving walls of a shell body, which are different in height. CONSTITUTION:An outer shell 1 consists of a shell body 3 for covering the lower portion below an ankle and an upper shell 4 for covering the upper portion above an ankle. The shell body 3 and the upper shell 4 are connected together by a rotary shaft 5 near the inner and the outer hollow. A long hole 6 is made on the back face of the upper shell 4 in the right-left direction, and an adjusting block 7 protruding form the inner surface of the upper shell 4 is fitted in it to be able to move in the right and left directions. When the adjusting block 7 is moved to the middle of the long hole 6 so that the adjusting block 7 comes in contact with a receiving wall 13 of the shell body 3 at its uppermost position when the upper shell 4 is turned forward, the obtained forward inclination power is small. Then, when the adjusting block 7 is moved to the right side of the long hole 6 so that the adjusting block 7 comes in contact with the receiving wall 13 of the shell body 3 and when the upper shell 4 is turned forward, a large forward inclination power is obtained.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a device for adjusting the magnitude of the repulsive force that the front part above the ankle receives from a ski boot when leaning forward, that is, the magnitude of the forward leaning power. It is something.

[Conventional technology and its problems]

In recent years, most ski boots have an inner boot inserted into an outer shell made of synthetic resin.

In this type of ski shoe, the outer shell is composed of at least two members: a shell body that covers the area below the ankle, and an upper shell that covers the area above the ankle. They are connected to each other by a pivot shaft near the ankles, and when the upper shell is tilted forward, the upper shell bends forward relative to the shell body.

By the way, the amount of forward leaning power received from the ski boot when leaning forward varies depending on the amount of forward bending resistance of the upper shell, but forward leaning power is very important for ski operation, and skiers The amount of forward leaning power required differs depending on the skill of the skier.

For this reason, there is a need for ski boots that can adjust the amount of forward leaning power with simple movements.

Therefore, the present invention aims to make it possible to adjust the magnitude of forward leaning power in ski boots with a simple operation.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention provides an adjustment block movable in the left-right direction at the lower part of the inner back surface of the upper shell. A plurality of receiving walls that the adjustment block hits when rotated are provided at different heights in the left and right direction.

[Effect]

By tilting forward, the upper shell tries to rotate forward relative to the shell body around the rotation axis, but at this time, until the adjustment block of the upper shell hits the receiving wall of the shell body, the upper shell almost rotates forward. When the adjustment block rotates without bending resistance and hits the receiving wall of the shell body, the forward bending resistance increases and the forward tilting power obtained also increases.

Therefore, the forward tilting power can be adjusted by moving the adjustment blocks from side to side so that the adjustment blocks come into contact with the receiving walls of the shell body at different height positions.

〔Example〕

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

The ski boot consists of an outer shell 1 made of synthetic resin and an inner boot 2 inserted into the outer shell 1.

The outer shell 1 consists of a shell body 3 that covers the lower part from the ankle, and an upper shell 4 that covers the upper part from the ankle, and the shell body 3 and the upper shell 4 are connected to each other by a rotation shaft 5 near both the medial and lateral ankles. The upper shell 4 is bent forward with respect to the shell body 3.

A long hole 6 is formed in the back side of the upper shell 4 in the left-right direction. An adjustment block 7 is fitted into the elongated hole 6 so as to protrude toward the inner surface of the upper shell 4 so as to be movable in the left-right direction. The adjustment block 7 is provided with guide pieces 8 on the upper, lower, left and right sides, and guide grooves 9 are provided on the inner surface of the upper shell 4 on the upper, lower, left and right sides of the elongated hole 6.
A guide piece 8 is fitted so as to be movable in the left-right direction along the guide groove 9. Further, a knob 10 is formed in the adjustment block 7 so as to protrude from the elongated hole 6 toward the outer surface of the upper shell 4 .

On the other hand, a plate 11 is integrally attached to the back of the shell body 3, and this plate 11 is provided with a recess 12 into which the adjustment block 7 of the upper shell 4 is fitted. The receiving wall 13, which the adjustment block 7 hits when rotated to It is set up so that

In the ski boot having the above structure, the forward leaning power can be adjusted as follows.

For example, hold the knob 10 of the adjustment block 7, move the adjustment block 7 to the center of the elongated hole 6, and rotate the upper shell 4 forward, as shown in FIGS. 2 and 4. If the adjustment block 7 is brought into contact with the receiving wall 13 at the highest position of the shell body 3, no large bending stress is applied to the upper shell 4 until the adjustment block 7 comes into contact with the receiving wall 13. Since the upper shell 4 rotates forward, the obtained forward tilting power is small.

On the other hand, for example, hold the knob 1'0 of the adjustment block 7 and move the adjustment block 7 to the right side of the elongated hole 6,
If the adjustment block 7 immediately contacts the receiving wall 13 of the shell body 3 when the upper shell 4 is rotated forward, a large bending stress will be applied to the upper shell 4, making it difficult to obtain a large forward tilting power. can.

Therefore, by holding the knob 10 and moving the adjustment block 7 from side to side, the forward tilting power can be adjusted.

〔Effect of the invention〕

As described above, according to the present invention, the forward leaning power of ski boots can be adjusted with a simple operation.
