Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ski shoe having an outer shell and an inner boot inserted into the outer shell.
In particular, the present invention relates to a ski boot having a foot tightening mechanism that tightens and releases the front part of the ankle from the outer surface of the inner boot in conjunction with opening and closing of the rear cuff of the outer shell.

[Conventional technology]

As a ski boot consisting of an outer shell and an inner boot having a tightening mechanism for fixing the skier's feet, there is known a ski shoe disclosed in Japanese Patent Application Laid-open No. 118360/1983.

In the above-mentioned known ski boots, one end of the cable is connected to a presser member arranged so as to be distributed over a desired area on the front side of the ankle of the inner boot inserted into the outer shell, and the cable is guided toward the other end of the cable and the heel of the outer shell. At the same time, the other end is connected to a leg tightening device provided on the rear cuff of the outer shell, and when the rear cuff is tightened and fixed to the front cuff of the outer shell by the tightening device, the presser member tightens the ankle in conjunction with this, It is designed to securely secure the ski boot to the skier's foot.

Therefore, by putting the skier's foot inside the inner boot and tightening the rear cuff with the tightening device provided on the front cuff, the presser member can tighten the front part of the ankle from above the inner boot.
It is easy and convenient to tighten as it does not require any manual operation, but on the other hand, when the legs tilt forward when gliding, etc., the front and rear cuffs of the outer shell also tilt forward. As a result, a tensile force is generated in the cable, which causes the presser member to tighten the ankle portion more strongly than necessary. This causes problems such as pain in the skiers' feet and an inability to withstand long periods of skiing.

Therefore, conventionally, as disclosed in JP-A-59-137001 and JP-A-60-225502, a through-hole that curves in the radial direction of the rear cuff is provided in the pivot shaft of the rear cuff. A cable connected to the pressure part on the ankle is inserted into this through hole, and as the skier's leg leans forward during skiing, the rear cuff of the outer shell tilts forward around the pivot axis. This prevents any tensile force from being generated in the cable even when the cable is pressed, and prevents an increase in the pressing force applied to the ankle by the pressing pad.

[Problem that the invention attempts to solve]

In the conventional ski boots with a foot tightening mechanism as described above, the cable for tightening the pressing part is inserted and guided through a radial through hole formed in the rear cuff pivot shaft. Even if the cable is rotated backward using the cable as a fulcrum and released, the tensile force applied to the cable by the tension lever does not deform in any way.
The pressure pad still presses the front part of the ankle, making it difficult to smoothly insert and remove the foot from the inner boot, which causes undue force to be applied to the foot, causing pain, and causing damage to the inner boot. It becomes difficult to insert the legs. Therefore, when removing your foot from the inner boot of ski boots or wrapping your foot in the inner boot, rotate the tension lever in the direction to release it to release the pressing force from the pressure part, and then rotate the rear cuff backward. need to be moved. This not only makes the operation relatively complicated and troublesome, but also causes the problem of forgetting to tighten the tension lever.

[Purpose of invention]

The present invention was developed to solve the above-mentioned conventional problems, and by releasing the rear cuff without releasing the tension lever, it is possible to release the pressure of the presser member against the front of the ankle. The purpose of the present invention is to provide ski shoes that are designed to be simple.

[Means for solving problems]

The ski boots according to the present invention include an outer shell having a front cuff attached to the shell body by a pivot pin and a rear cuff attached to the shell body so as to be rotatable in the front and back direction by a pivot pin, and the ski boot is inserted into the outer shell. In the ski boots equipped with an inner boot, a cable is placed on the front part of the ankle of the inner boot, and the cable is pulled out of the rear cuff along the inner wall of the heel cover of the shell body, and the foot strap is attached to the rear cuff. A guide portion for guiding the cable midway is provided on the inner wall of the heel covering portion of the shell body, which is connected to the attaching device and further located at the front lower part of the toe portion side of the pivot pin of the rear cuff.

[Effect of invention]

In this invention, the cable connecting the foot clamp and the foot tightening device provided on the rear cuff is guided by the guide section at the front lower part of the toe side of the rear cuff pivot pin, so that the rear cuff can be tilted to the open state. When this happens, the cable can be loosened without releasing the foot tightening device, and the pressing force of the cable on the front of the ankle can be released simply by tilting the rear cuff backwards. .

[Example of idea]

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 is an overall side view of a ski boot shown with a part cut away, and the ski boot indicated by the overall reference numeral 1 is roughly divided into an outer shell 2 molded from a hard and tough synthetic resin material, and an outer shell 2 formed from a hard and tough synthetic resin material. It consists of an inner boot 3 inserted inside.

The outer shell 2 is composed of a shell main body 4 that mainly covers the area below the ankle, a front cuff 5 that covers the front part of the ankle to the lower part of the shin, and a rear cuff 6 that covers the area from the upper heel to the lower part of the calf. The lower ends of the front cuff 5 and the rear cuff 6 are pivotally attached to the inner and outer ankle portions of the shell main body 4 by pins 7a and 7b so as to be rotatable in the front-rear direction. Further, the back surface portion 3a of the inner boot 3 that overlaps with the rear cuff 6 can be opened and closed integrally with the rear cuff 6. A tightening buckle 8 is fixed to one side of the upper part of the front cuff 5.
One end of the tightening band 9 that engages with the buckle 8
The front cuff 5 is fixed to the opposite side of the front cuff, and its free end is wrapped around the outer periphery of the rear cuff 6, and its end is connected to the buckle 8.
and the rear cuff 6 are tightened together.

Further, in FIG. 1, reference numeral 10 denotes a presser pad for pressing the foot against the shell main body 4, and this presser pad 10 is attached to the outer surface of the inner boot 3 located at the boundary between the top of the foot and the ankle. A cable 12 connected to a foot tightening device 11 is connected to the left and right edges of the presser pad 10.

The foot tightening device 11 is installed so as to be housed in a recess 6a formed on the lower back surface of the rear cuff 6, and its lower end is attached to the recess 6a by a pin 13 so as to be rotatable in the front-rear direction. Tightening lever 1
4, an adjusting screw rod 15 that passes through the tightening lever 14 in the longitudinal direction and has both ends rotatably pivoted to the tightening lever 14, and is threadedly engaged with the screw rod 15 and cannot rotate around the axis of the screw rod 15. Tightening lever 1
4 and is slidable in the longitudinal direction of the tightening lever 14 by a screw lead of the screw rod 15, and an adjustment knob 17 fixed to the upper end of the screw rod 15,
The cable 12 is attached to the nut member 16.
are connected.

Cable 12 connected to the nut member 16
have a pair of through holes 18a and 18b having the same length, and the other end is formed at both corners of the lower end of the recess 6a of the rear cuff 6 (see FIG. 2).
The elongated holes 19a, 1 are drawn into the inside of the rear cuff 6 through the holes 19a, 1 formed in the heel cover portion 4a of the shell body 4 near both pivot pins 7a, 7b of the rear cuff 6.
9b (see FIGS. 1 and 2), and is inserted into the inside of the shell body 4, and further passed between the shell body 4 and the inner boot 3, and is connected to the left and right edges of the presser pad 10 via a connector 20. Also,
The heel bottom 4 of the shell main body 4 is biased below the middle of the pivot pins 7a and 7b on both left and right sides of the front cuff 5 and rear cuff 6, preferably toward the pivot pin 7b side.
On the b-side inner wall, there are cable guide sections 21a and 21a, respectively.
21b is provided protrudingly, and this cable guide portion 2
By hooking the left and right cables 12, 12 to 1a, 21b, a force is generated that presses the foot toward the heel of the shell body 4 on the presser foot pad 10, and the lid 6 is simply tilted to the open state. The cable 12 is now loosened.

In the ski boots constructed as described above, when the ski boots are attached to the skier's feet, the tightening band 9 is released from the buckle 8 and the rear cuff 6 and the back part 3a of the inner boot 3 are attached as shown in FIG. Tilt it to the position shown by the dotted chain line. At this time, the foot tightening device 11 is stored in the recess 6a of the rear cuff 6,
Although it is set in a state where a tightening force is applied to the presser pad 10, when the rear cuff 6 is tilted to the position shown by the two-dot chain line in FIG. , 18b is inserted into the elongated hole 19.
a, 19b to the lower end and the rear cuff 6 is tilted to the position indicated by the two-dot chain line.
The length L' between b is 1 minute shorter than the length L in the state shown by the solid line in FIG. As a result, the cable 12 is slackened by 1 minute, and the presser pad 10 is in the state shown by the first two-dot chain line. Also,
At this time, the through holes 18a and 18b of the rear cuff 6 are
The cables 12, 12 move on the track 6b in FIG. 1 with the pin 7b as the rotation axis, and the cables 12, 12 move on the track 12a in FIG. 1 with the cable guides 21a, 21b as the rotation axis. And two orbits 6b,
In the region X where the cable 12a separates, the cable 12
The length of the cable 12 becomes longer, and the cable 12 becomes slack. In other words, the pressing force of the inner boot 3 on the front part of the ankle is released,
There is no need to tilt the tightening lever 14 in the direction of releasing the tightening force.

In this state, if the skier's foot is inserted into the inner boot 3 through the open mouth of the rear cuff 6, it can be inserted smoothly without being restrained by the presser pad 10 and without causing any pain to the foot.

Next, after the skier's foot is completely inserted into the inner boot 3, the jacket 6 is closed and the band 9 is passed through the buckle 8 and tightened, and the front cuff 5 and rear cuff 6 of the outer shell 2 are fixed to the leg. At the same time, a tensile force is generated in the cable 12, and the presser pad 10 presses the front part of the ankle from the upper surface of the inner boot 3, thereby reliably fixing the entire foot to the shell body 4.

On the other hand, when a skier's leg leans forward while skiing, the front cuff 5
And the rear cuff 6 also has respective pivot pins 7a, 7b.
Although the guide part 2 of the cable 12 is tilted forward using the fulcrum,
1a and 21b are located forward of the pivot pin 7b of the rear cuff 6, that is, on the toe portion 4c side of the shell body 4, as shown in FIG. does not occur. In addition, the through holes 18a and 18b of the rear cuff 6
Looking at the track 6b and the track 12a of the cable 12, in the region Y where both tracks 6b and 12a are separated, the length of the cable 12 becomes longer and the cable 1
2. It has a relaxing effect. Therefore, pressure exceeding the set value is not applied to the front part of the ankle, and the user can enjoy skiing for a long time without injuring his or her feet.

In addition, when taking off the ski boots, all that is required is to remove the band 9 from the buckle 8 and then tilt the rear cuff 6 to the position shown by the two-dot chain line in Figure 1.
There is no need to tilt the 4. Therefore, the operation of putting on the ski boots is simplified, and the problem of forgetting to tighten the tightening lever 14, which is conventional, can be eliminated.

In addition, when adjusting the tightening force of the presser pad 10 on the front part of the ankle, use the knob 17 to tighten the screw rod 1.
5 to move the position of the nut member 16 in the vertical direction.

In the present invention, the presser pad 10 is used, but the cable 12 may be used to press the front part of the ankle of the inner boot 3. Alternatively, the ski boots may be put on and taken off with the tightening lever 14 tilted rearward.

[Effect of idea]

As described above, according to the present invention, by providing the cable guide section at the bottom of the shell body at the front lower part on the toe side of the rear cuff from the pivot pin, the cable guide section is provided at the bottom of the shell body at the front lower part of the rear cuff on the toe side. Due to the difference in the trajectory of the guide part and the fulcrum (pivot pin) of the rear cuff that has the leg tightening device to which the cable is connected, the length of the cable from the cable guide to the leg tightening device of the rear cuff is longer than that of the rear cuff. Since slack will occur when leaning backwards or forwards, the tightening force on the cable can be released by simply tilting the rear cuff backwards without releasing the foot tightening device, and the tightening force on the cable can be released. In addition to making it easier to put on and take off, even if the rear cuff is tilted forward by tilting the legs forward when gliding, etc., this will not cause tension on the cable and create a tightening force on the cable. The effect is that you can enjoy skiing for a long time without causing any pain to your feet.
