Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a forward tilt power adjustment device for a ski boot.

[Conventional technology and its problems]

Conventionally, ski shoes consist of an outer shell made of synthetic resin and an inner boot that is inserted into the outer shell. It is composed of three parts: a front cuff that covers the area from the heel to the calf, and a rear cuff that covers the area from the heel to the calf. There is one that is rotatably attached to the side point.

In this type of ski boot, when force is applied to the front when leaning forward, the front cuff and rear cuff rotate forward around the side points. This rotational movement occurs with almost no resistance until the lower front edge of the front cuff comes into contact with the upper surface of the shell of the shell body, but after the lower front edge of the front cuff comes into contact with the upper surface of the shell of the shell body, bending stress occurs in the front cuff made of

The repulsive force generated by the bending stress of the front cuff, that is, the forward leaning power, is a very important point in skiing operation, and the optimal forward leaning power for these ski boots varies depending on the skill of the skier. It's different.

However, the problem with conventional ski boots is that it is extremely difficult to adjust the forward leaning power.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a forward tilting power adjusting device that can extremely easily adjust the forward tilting power of a ski boot.

[Means for solving problems]

In order to solve the above problems, this invention
In the ski boots as described above, a protrusion is formed on the surface of the shell body from the side point toward the instep, a protrusion opposite to the rear surface of the protrusion is formed on the back surface of the front cuff, and the protrusion on the ciel body is formed on the back surface of the front cuff. A sliding block is fitted into the gap formed between the front cuff and the protrusion of the front cuff so as to be movable in the vertical direction.

[Effect]

By the way, when the front cuff and rear cuff are rotated forward about the side points, the sliding block is pressed against the rear surface of the projection of the shell body by the protrusion of the front cuff, and the sliding block prevents the front cuff from tilting forward. It becomes a resistance to exercise.

For this reason, a repulsive force, that is, forward tilting power, is generated in the front cuff, but the resistance force against the forward tilting movement of the front cuff by the sliding block becomes maximum as the position of the sliding block moves upward from the side point. Therefore, it increases. Conversely, the closer the position of the sliding block is to the side point, the smaller the resistance to the forward tilting movement of the front cuff.

Therefore, by moving the position of the sliding block in the vertical direction, the resistance force against the forward tilting movement of the front cuff changes, so that the forward tilting power of the ski boot can be adjusted.

〔Example〕

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

The ski shoes 1 have outer shells 2 made of synthetic resin.
and an inner boot 3 inserted into the outer shell 2.

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. 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 ankles of the shell body 4, respectively. A stepped portion 8 is formed on the instep of the front side of the ankle of the above-mentioned 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. At the rear ankle portion of the stepped portion 8 of the shell body 4, a protrusion 9 is formed extending 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 substantially oppose the stepped portion 8. In addition, a locking step 10 is formed on the back surface of the front cuff 5 along the lower front edge thereof, and this locking step 10 is used when the front cuff 5 is placed on the shell body 4. When the front cuff 5 rotates rearward around the side point 7, it comes into contact with the front side of the protrusion 9 of the shell body 4 and prevents the front cuff 5 from rotating rearward. I'm starting to do that. 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 outer front cuff 5 of both the inner and outer sides of the front cuff 5, a protrusion 13 is provided diagonally upward from the side point 7 and parallel to the protrusion 9, facing the rear surface of the protrusion 9 of the shell body 4. A gap 14 is formed between the front surface of the protrusion 13 and the rear surface of the protrusion 9. In this gap 14,
A sliding block 15 is fitted so as to be vertically movable. A long hole 16 is formed diagonally above the side point 7 of the outer front cuff 5 in the vertical direction corresponding to the gap 14. A bolt shaft 18 of a bolt 17 is inserted into the elongated hole 16 from the outside to the inside of the front cuff 5, and the bolt shaft 18 is screwed into a bolt hole 19 formed in the sliding block 15. Therefore, by tightening this bolt 17, the sliding block 15 is pressed against the back surface of the front cuff 5, thereby fixing the sliding block 15 to the front cuff 5.

When the sliding block 15 is fixed upwardly away from the side point 7 in this way,
When the front cuff 5 is rotated forward about the side point 7, the resistance force against the forward tilting movement of the front cuff 5 increases as the sliding block 15 moves away from the side point 7, so that it is generated in the front cuff 5. The repulsive force, that is, the forward leaning power increases.

On the other hand, when the sliding block 15 is fixed at a lower position, the resistance force against the forward tilting movement of the front cuff 5 is reduced, and the forward tilting power is thereby also reduced.

Therefore, by moving the sliding block 15 in the vertical direction, the forward tilting power is changed.

The forward tilt power adjustment device having the above structure can be provided not only on the outer surface of the ski boot but also on the inner surface.

In this way, when the forward leaning power adjustment device is provided on both the inner and outer sides of the ski boot, it is possible to create a difference in the forward leaning power on the inner and outer sides of the ski boot, so the direction in which the skier puts his/her knees in can be adjusted. Adjustment is also possible.

However, when the forward tilt power adjustment device of the above structure is installed on the inside surface of the ski boot, the head 20 of the bolt 17 protrudes from the inside surface of the ski boot, so the edge of the ski touches the head 20 of the bolt 17. There is a risk of getting caught, causing problems in ski operation.

For this reason, the sliding block 1 on the inside surface of the ski boot
5', as shown in FIGS. 2 to 5, 6, or 7 to 10, so as to move together with the sliding block 15 on the outer surface of the ski boot,
The bolts for fixing the sliding block 15' on the inner surface may be omitted.

In the embodiment shown in FIGS. 2 to 5, bands 21 and 21' of metal or the like formed along the outer surface of the shell body 4 are attached to both the inner and outer sliding blocks 15 and 15', respectively. A pinion 22 is attached to the shell body 4 between the opposing band members 21 and 21', and a rack gear 23 that is threaded onto the pinion 22 is attached to the shell body 4 between the band members 15 and 15'. It is formed on the surface. Therefore, the outer sliding block 1
If you move 5 upward, the inner sliding block 1
5' also moves upward.

In the embodiment shown in FIG. 6, both the inner and outer sliding blocks 15, 15' are connected by a band 24 made of metal or the like formed along the outer surface of the shell body 4. Therefore, if the outer sliding block 15 is moved upward, the inner sliding block 15' will be moved downward, so that the gap 1 into which the inner sliding block 15 is fitted will be moved downward.
4' is formed so that it gradually becomes wider toward the upper side, so that as the sliding block 15' moves downward, the resistance force against the forward tilting movement of the front cuff 5 increases. There is.

In addition, in the embodiment shown in FIGS. 7 to 10, pulleys 25 are provided at both the inner and outer side points 7.
25' is attached rotatably, and this pulley 25,
A wire 26 is wrapped around the wire 25' in an endless manner, and both the inner and outer sliding blocks 15, 15' are connected to the wire 26.
is installed. The above sliding blocks 15, 15'
Two through-holes 27 and 28 are formed in parallel, and the inner diameter of one of the through-holes 28 is larger than the outer diameter of the wire 26, so that when the wire 26 is inserted into the through-hole 28, the wire 26 Through hole 2
8 so that it can slide. Further, the inner diameter of one of the through holes 27 is formed to be almost the same as the diameter of the wire 26, and when the wire 26 is inserted into the through hole 27, the sliding blocks 15, 15' are immovably fixed to the wire 26. It is becoming more and more common. The positions of the through holes 27, 28 formed in both the inner and outer sliding blocks 15, 15' are reversed in both the inner and outer sliding blocks 15, 15'. That is, in the outer sliding block 15',
A wire 26 is fixed to a sliding block 15' having a through hole 27 formed on the front side, and a through hole 28 is formed on the rear side, through which the wire 26 is slidably inserted. On the other hand, the inner sliding block 1
5, a through hole 27 is formed on the rear side to fix the sliding block 15 and the wire 26, and a through hole 28 is formed on the front side to allow the wire 26 to be slidably inserted therethrough. As a result, when the outer sliding block 15 is moved upward, the inner sliding block 15' is moved upward.

〔effect〕

As described above, according to the present invention, the forward tilting power of the ski boot can be arbitrarily and easily adjusted.
