Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to ski boots that can increase the forward leaning power when skiing and release the forward leaning power when walking.

[Conventional technology and problems]

Conventionally, ski shoes have consisted of an outer shell made of synthetic resin and an inner boot inserted into the outer shell. and a front cuff that covers the area from the heel to the calf.
There is a shell body constructed of three members, a rear cuff that covers the shell body, and the lower ends of both sides of the front cuff and rear cuff are rotatably attached to side points below both the inner and outer ankles of the shell body.

When this type of ski shoe leans forward, the bending stress of the front cuff generates a repulsive force, in other words, forward leaning power. This forward leaning power is a very important point in skiing operation, and is suitable for advanced skiers. This requires great forward leaning power.

However, if the power at the front of the ski boots is high, the front cuff will be difficult to bend forward, making it difficult to walk.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a ski boot that can increase the forward leaning power when skiing and release the forward leaning power when walking by a simple operation.

[Means for solving problems]

In order to solve the above problems, the present invention provides ski boots as described above, in which a protrusion is formed on the surface of the shell body from the side point toward the instep, and the above-mentioned protrusion is formed above the side point on the front cuff surface. A protrusion is formed opposite to the rear surface of the protrusion, and a fixing block that can be freely fitted into and removed from the gap formed between the protrusion and the protrusion is movable along the protrusion of the shell body. (Operation) With the fixing block fitted into the gap formed between the protrusion of the shell body and the protrusion of the front cuff, rotate the front cuff and rear cuff forward about the side points. In this case, the protrusion of the front cuff presses the fixed block against the rear surface of the protrusion of the shell body, and the fixed block acts as a resistance to the forward tilting movement of the front cuff, generating a large forward tilting power on the front cuff.

On the other hand, when the fixed block is removed from the gap formed between the protrusion of the shell body and the protrusion of the front cuff, the fixed block does not provide resistance to the forward tilting movement of the front cuff.

Therefore, when sliding, the forward tilting power can be easily increased by fitting the fixed block into the gap formed between the protrusion of the shell body and the protrusion of the front cuff. If it is removed from the gap, the large forward leaning power during sliding can be released, making it easier to walk.

〔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 made of synthetic resin and an inner boot 3 inserted into the outer shell 2.

The outer shell 2 includes a shell body 4 that covers the lower part from the ankle, a front cuff 5 that covers the ankle and the ankle,
It is composed of three members: a rear cuff 6 that covers the heel to the shin portion. The lower ends of both sides 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 heels of the elbow body 4, respectively. A stepped portion 8 is formed on the instep of the front of the ankle of the shell body 4 from both sides to the upper surface, and when the front cuff 5 rotates forward about the side point 7, the front part of the front cuff 5 The lower edge comes into contact with the stepped portion 8, and the front cuff 5 is prevented from rotating forward any further. Step portion 8 of the shell body 4
A protrusion 9 is formed at the rear ankle portion of the shell body 4 from both sides of the shell body 4 to the upper surface of the upper surface of the front surface of the ankle so as to be substantially opposite to the stepped portion 8 . Further, a locking step 10 is formed on the back surface of the front cuff 5 along the front lower edge of the front cuff 5, and this locking step 10 is used when the front cuff 5 is placed on the shell body 4. When the front cuff 5 is located on both front sides of the protrusion 9 of the body 4 and rotates backward around the side point 7, it comes into contact with the front surface of the protrusion 9 of the shell body 4 and moves to the rear side of the front cuff 5. It is designed to prevent the rotation of the Buckles 11 and 12 for integrally connecting the front cuff 5 and the rear cuff 6 are provided on the rear side surface of the front cuff 5 at the top and bottom.

On the back surface of the front cuff 5, protrusions 13 and 13' are provided diagonally upward from both side points 7 and parallel to the protrusion S, respectively, facing the rear surface of the protrusion 9 above the shell body. A gap 14.14' is formed between the front surface of 13.13' and the rear surface of the protrusion S. This gap 14
．． A fixing member 15, 15', which can be freely inserted into and removed from 14', is fitted between the front surface of the shell body 4 and the back surface of the front cuff 5 so as to be movable along the protrusion 9.

The fixed blocks 15.15' are provided on both the inner and outer sides of the front cuff 5, and when the outer fixed block 15 is moved, the inner fixed block 15 ' is also moved at the same time, so that the fixed blocks 15.15' on both the inner and outer sides are fitted into and removed from the gap 14.14' at the same time. This fixed block on both the inside and outside 15.15

Examples include those shown in the figure.

In both the embodiments shown in FIGS. 3 and 5, a long hole 16 is formed in the front cuff 5 extending from a position diagonally above the side point 7 on the outside of the front cuff 5 to the center position of the gap 14. has been done.

A shaft 17 that slides in the elongated hole 16 is protruded from the upper surface of the outer fixed block 15, and an operating block 18 that slides on the surface of the front cuff 5 is attached to the upper end of this shaft 17. There is. This operation block 18 is connected to the shaft 17 through the elongated hole 1.
When the fixed block 15 is moved upward to the position where it contacts the upper end of the operating block 1, the fixed block 15 fits into the gap 14, and conversely, the operating block
8 is moved downward to a position where the shaft 17 abuts the lower end of the elongated hole 16, the outer fixing block 15 is removed from the gap 14.

In the embodiment shown in FIG. 3, both the inner and outer blocks 15 are connected by a band 19 made of metal or the like formed along the outer surface of the shell body 4.

This allows the outer fixed block 15 to be moved to the operating block 1.
