Abstract

PURPOSE:To make possible to adjust the strength of forward inclining power with a simple operation by rotatably providing the axis body on the upper fringe of a shell body, making the axis body projected into a through hole on the lower fringe of the top portion shell, and fastening an adjusting block eccentrically to the axis body. CONSTITUTION:When a top shell 4 is forward rotated around the rotation axis 5 of the shell body 3, an elastic member 14 on the periphery is only deformed until an adjustment block 13 in a through hole 12 of the top shell body 4 is accepted by the inner wall so that bending stress is not much applied to the top shell 4, and the forward incling power obtained therein is small. However, when the adjustment block 13 is accepted by the inner wall of the through hole 12, a large bending stress is applied and forward inclining power obtained becomes gradually larger. Then the rotation of the adjustment block 13 centering on the axis body 11 allows the change of distance between the adjustment block 13 and the inner wall of the through hole 12 to enable the adjustment of the forward inclining power.

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 near the section, so that when 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 a simple operation.

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

[Means to solve the problem]

As a first means for solving the above problems, the present invention provides a rotatable shaft at the lower edge of the upper shell that overlaps the upper edge of the shell body, and extends the shaft through the upper shell. An adjustment block is fixed at the end in a state eccentric to the shaft body, and the adjustment block is received by the outer surface of the shell body when the upper shell is rotated forward around the rotation axis of the shell body. It formed a receiving wall.

In addition, as a second means to solve the above problems,
In this invention, a shaft is rotatably provided on the upper end edge of the shell body where the lower end edge of the upper shell overlaps, the shaft is made to protrude into a through hole formed in the upper shell, and the shaft inside the through hole has a The adjustment block was fixed eccentrically with respect to the shaft.

[Effect]

By employing the first means above, when the upper shell is rotated forward around the rotation axis of the shell body by forward tilting, the upper shell is subjected to bending stress until the adjustment block is received by the receiving wall. However, when the adjustment block is received by the receiving wall, a large bending stress is applied to the upper shell, and the resulting forward tilting power increases.

When the shaft body is rotated and the adjustment block is rotated, the distance between the adjustment block and the receiving wall changes because the adjustment block is fixed eccentrically with respect to the shaft body.

Therefore, by rotating the adjustment block, the forward tilting power can be adjusted.

In addition, by adopting the second means described above, when the upper shell is rotated forward around the rotation axis of the shell body by forward tilting, the adjustment block in the through hole of the upper shell will touch the inner wall of the through hole. Until the adjustment block is received, the upper shell is not subjected to much bending stress and the obtained forward tilting power is small. However, when the adjustment block is received by the inner wall of the through hole, a large bending stress is applied to the upper shell and the obtained forward tilting power is small. The tilting power also increases.

Then, when the shaft body is rotated to rotate the adjustment block, the distance between the adjustment block and the inner wall of the through hole changes because the adjustment block is fixed eccentrically with respect to the shaft body.

Therefore, by rotating the adjustment block, the forward tilting power can be adjusted.

[Example] Hereinafter, an example of the present invention will be described based on the accompanying drawings.

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

The outer shell 1 is composed of a shell body 3 that covers the area below the ankle, and an upper shell 4 that covers the area above the ankle. The upper shell 4 is connected to the shell body 3 so that it can be bent forward.

A first embodiment of the invention is shown in FIGS. 1-6.

In this first embodiment, a shaft body 6 is rotatably provided on the lower edge of the back surface of the upper shell 4, which overlaps the upper edge of the shell body 3. This shaft body 6 passes through the upper shell 4, a knob 7 is fixed to the outer end of the upper shell 4, and an adjustment block 8 is fixed to the inner end of the upper shell 4. .

The adjustment block 8 is made of hard synthetic resin and has a rectangular shape, and is eccentrically fixed to the shaft body 6. Furthermore, a soft elastic member 9 made of rubber or the like is integrally attached to one example of the adjustment block 8.

A receiving wall 10 is formed on the outer surface of the rear surface of the shell body 3 to receive the adjustment block 8 when the upper shell 4 is rotated forward about the rotation axis 5 of the shell body 3.

In the first embodiment described above, when the shaft body 6 is rotated by holding the knob 7 so that the distance between an example of the adjustment block 8 and the receiving wall 10 becomes the closest as shown in FIG. When the upper shell 4 is rotated around the rotation axis 5 of the shell body 3 by tilting forward, the adjustment block 8 immediately comes into contact with the receiving wall 10 and a large bending stress is applied to the upper shell 4, causing the greatest forward tilt. Gain power.

Next, when the shaft body 6 is rotated by holding the knob 7 so that the elastic member 9 is fitted between the adjustment block 8 and the receiving wall 10 as shown in FIG. 5, the upper part is tilted forward. When the shell 4 is rotated around the rotation axis 5 of the shell body 3, the adjustment block 8 is received by the receiving wall 10 after the elastic member 9 is deformed, so that only the deformed bone of the elastic member 9 is attached to the upper shell 4. Such bending stress is reduced, and the resulting forward tilting power is smaller than in the case of FIG. 4.

Further, when the shaft body 6 is rotated by holding the knob 7 so that the distance between one side of the adjustment block 8 and the receiving wall 10 is the greatest as shown in FIG. 6, the upper shell is tilted forward. When the upper shell 4 is rotated around the rotation axis 5 of the shell body 3, almost no bending stress is applied to the upper shell 4 until the adjustment block comes into contact with the receiving wall 10, so the resulting forward tilting power is as shown in Figure 5. is even smaller than in the case of .

Therefore, in the first embodiment, the forward tilting power can be adjusted by holding the knob 7 and rotating the adjustment block 8, and the magnitude of the forward tilting power is indicated on the outer surface of the knob 7. The display is drawn.

Next, FIGS. 7 to 9 show a second embodiment of the present invention.

In this second embodiment, a shaft body 11 is rotatably provided on the back surface and the front side of the upper edge of the shell body 3, where the lower edge of the upper shell 4 overlaps.

The upper shell 4 also has a circular through hole 1 that is considerably larger than the shaft 11 so that the shaft 11 is located in the center.
2 is formed, and the shaft body 11 projects into the through hole 12.

The shaft body 11 in the through hole 12 has an adjustment prong 13.
is fixed. The adjustment block 13 is made of hard synthetic resin and has a triangular shape, and is eccentrically fixed to the shaft body 11. Around this adjustment block 13,
A soft elastic member 14 made of rubber or the like is integrally attached to fill the space between the through hole 12 and the inner wall.

In the second embodiment, when the upper shell 4 is rotated forward about the rotation axis 5 of the shell body 3 by forward tilting, the adjustment block 1 in the through hole 12 of the upper shell 4
Until the adjustment block 3 is received by the inner wall of the through hole 12, only the surrounding elastic member 14 is deformed, and the upper shell 4 is not subjected to much bending stress, and the obtained forward tilting power is small. When received by the inner wall of the through hole 12, a large bending stress is applied to the upper shell 4, and the resulting forward tilting power also increases.

Then, when holding the adjustment block 13 and rotating the adjustment block 13 around the shaft body 11, the adjustment block 13
is fixed in an eccentric state with respect to the shaft body 11, so the distance between the adjustment block 13 and the inner wall of the through hole 12 changes.

Therefore, by rotating the adjustment block 13, the forward tilting power can be adjusted.

[Effects of the Invention] As described above, according to the present invention, the forward tilting power of the ski boot can be adjusted with a simple operation.
