Description

[Detailed explanation of the invention] (a) Technical field of the invention This invention relates to ski boots, and more specifically, the forward tilt pressure can be adjusted using a band and a fastener that tighten the upper shell part corresponding to the ankle. It concerns the improvement of ski shoes.

(b) Prior Art and Problems Modern ski boots consist of a shell molded from a rigid plastic material and an inner boot that keeps the foot in close contact with the shell without any gaps. In order to hold the foot comfortably and stably inside the shoe and improve the operability of the ski when skiing, the upper part of the shell corresponding to the ankle is tightened with a tightening mechanism, or the instep of the foot is held. It is designed to provide a more secure ankle fit.

In addition, there is a known technology in which the tightening mechanism that tightens the upper part of the shell is equipped with a forward tilting pressure adjustment mechanism that allows the user to adjust how soft or hard the leg can be tilted forward in order to maintain an ideal forward leaning posture that does not fatigue the leg muscles. Yes, it is known in Japanese Patent Application Laid-Open No. 138246/1983.

The above-mentioned conventional ski boot tightening mechanism has a plurality of locking holes circumferentially formed on both the left and right sides of the upper flap of the ski boot, and the tightening collar is fastened at two locations in one of the locking holes with a stopper. By tightening the free end of the collar, which is fixed in position and wrapped around the rear support of the upper part of the ski boot, by means of a buckle connected to the corresponding fixed end of the collar, a predetermined stiffness (forward tilt) is achieved on the upper part of the ski boot. pressure).

However, when positioning and fixing the collar to the upper part of the ski boot, the conventional tightening mechanism as described above
Since a stopper is used that is separate from the upper part and the collar, changing the position of the locking hole in the collar is complicated, especially when trying to adjust the forward tilt angle and forward tilt pressure just before skiing. In addition to being extremely troublesome and time-consuming to change the collar stop position, skiers who are inexperienced in changing the collar stop position cannot do so without removing their feet from the ski boots. Moreover, since the fasteners are separated from the ski boots, there is a risk of them being lost, and the handling and management of the fasteners is troublesome.

(c) Purpose of the invention This invention was made in order to solve the conventional problems as described above, and it makes it possible to set the vertical position of the tightening band with respect to the upper shell of the boot with a single touch when adjusting the anteversion pressure. The purpose of the present invention is to provide ski shoes that can be easily adjusted and used even by inexperienced skiers with peace of mind.

(d) Structure of the invention In order to achieve the above object, the ski boot of this invention comprises a shell main body having a lower shell, an outer upper shell and an inner upper shell that are integrally provided on the left and right upper sides of this lower shell, and this shell. An inner boot inserted into the main body, a tiltable front cuff and a rear cuff that cover the front and rear openings between the outer upper shell and the inner upper shell, and a tiltable front cuff and rear cuff that extend along the outer surface of the outer upper shell in the vertical direction. a plurality of positioning engagement parts for setting the forward inclination pressure; a band body wound around the outer periphery of the upper shell and both cuffs; and a band body formed on the inner surface of one end of the band body for setting the forward inclination pressure of the outer upper shell. It consists of a fastening buckle which is attached to one of the positioning engagement parts and which locks with the free end of the band body.

(E) Example of the invention An example of the invention will be described below with reference to the drawings.

Figures 1 to 7 show an example of a ski boot equipped with a tightening mechanism having a forward tilting pressure adjustment function according to this invention. 1 is a shell body made of a rigid plastic material such as polyurethane; ,
This shell main body 1 consists of a bottom part 2, a lower shell 3 that covers the foot part, and outer and inner upper shells 4a and 4b that cover both left and right sides of the ankle part. The upper shells 4a and 4b are shaped to cover both left and right sides of the ankle portion, so that the front and rear portions thereof are open and tilted forward, and each opening at the front and rear portions is opened at the front and rear portions. The upper shells 4a and 4b are closed from the inside by the cuff 5 and the rear cuff 6, and the lower ends of the front cuff 5 and the rear cuff 6 have a lower part as shown in FIG. 2 so that they can be tilted back and forth. The cuffs 5 and 6 are pivoted to the shell 3, and when the foot is inserted into the ski boot, the cuffs 5 and 6 are tilted outward as shown by the two-dot chain line in FIG.

7 is an inner boot molded from a flexible material that is interposed between the shell body and the skier's feet in order to fit the skier's feet into the shell body 1; 8 is an inner boot formed from a flexible material;
a, 4b, a tightening mechanism for tightening the outer periphery of the front cuff 5 and rear cuff 6, and setting the forward tilt angle of the leg and the forward tilt pressure on the leg.

As shown in FIG. 4, the tightening mechanism 8 has a band-shaped band member 9 made of plastic material, and the outer surface of one end of the band member 9 is provided with serrations over a desired length range. In addition to forming an unevenness 10, an engaging protrusion 11 connected to the outer upper shell 4a is integrally formed at the other end and projects inward, and further grips the unevenness 10 side of the band body 9. A buckle 12 for winding and tightening the upper shell portion is integrally attached, and this buckle 12 includes a frame 12a rotatably attached to one end of the band body 9, and a frame 12a rotatably attached to the frame 12a. A claw member 12 that is attached to the unevenness 10 of the band body 9
It is composed of b. In addition, the band body 9
A convex locking portion 13 for positioning the band body 9 with respect to the outer upper shell 4a is formed on the inner surface of the other end, and a convex locking portion 13 is formed on the inner surface of the intermediate portion of the band body 9. Convex locking parts 14a, 14b, 1 that set the forward inclination angle of the legs with respect to the bottom part 2
4c are formed in a plurality of rows, that is, three rows, in the longitudinal direction of the band body 9, and these locking portions 14a to 14c are engaged with the inner upper shell 4b.

In the outer upper shell 4a, FIGS. 1 and 6 are shown.
As shown in the figure, a large number of concave forward tilt pressure setting positioning locking portions 15 that lock the locking portions 13 of the band body 9 are formed at regular intervals along the longitudinal direction of the upper shell 4a. The elongated hole 16 located in the middle of the locking part 15 in the width direction is the outer upper shell 4a.
This elongated hole 16 is formed over the entire length of the recess array.
An engaging protrusion 11 of the band body 9 is slidably engaged inside. In addition, the inner upper shell 4
As shown in FIGS. 5 and 7, on the outer surface of b, a concave forward tilt pressure setting positioning engagement part 17 is provided opposite to the engagement part 15 of the outer upper shell 4a in the longitudinal direction of the shell 4b. A large number of locking portions 17 are formed at regular intervals along the band body 9, and one of the locking portions 14a to 14c for setting the forward tilt angle of the band body 9 is engaged with the locking portions 17.

Next, the operation of this embodiment configured as described above will be explained.

When the ski boots are attached to the skier's feet in a tight state, first, the engaging protrusion 11 of the band body 9 is inserted into the elongated hole 16 of the outer upper shell 4a, and the foot is inserted into the inner boot 7. After that, the band body 9 is attached to the shells 4a, 4b and the cuffs 5, 6.
Wrap it around the outer periphery of the locking section 13, engage the locking section 13 at one end with a desired portion of the positioning engagement section 15 in the vertical direction, and further one of the locking sections 14a to 14b on the other side.
For example, as shown in FIG.
7. In this state, the free end of the band body 9 is inserted into the buckle 12, and after the claw member 12b is engaged with the uneven portion 10, the buckle frame body 12a is tilted in the tightening direction. Then, due to the tightening force of the band body 9, the upper shells 4a, 4b including each cuff 5, 6 are
The whole thing is tightened. At this time, since the band portion 9a located on the front surface of the upper shell between the locking portions 13 and 14c is restrained by the engaging portions 15 and 17, a tightening force is applied to the band body 9 on this band portion. However, since a tightening displacement occurs in the direction of the arrow in FIG. 3 in the band portion on the free end side that is locked to the buckle 12, this tightening displacement causes almost no displacement in the direction of the arrow in FIG. Therefore, the rear cuff 6 side is narrowed down, thereby pushing the entire inner boot 7 including the rear cuff 6 toward the front cuff 5 side with the upper shells 4a and 4b as a reference. Therefore, the legs are forced to tilt forward with respect to the bottom 2 of the shell body 1. The forward tilting pressure at this time is set by the tightening force of the band body 9.

On the other hand, if it is desired to make the forward inclination angle of the inner boot 7 including the legs, the front cuff 5, and the rear cuff 6 larger than the state shown by the solid line in FIG. If the body 9 is tightened, the front cuff 5, rear cuff 6, and inner boots 7, including the legs, will be tilted forward as shown by the two-dot chain line in FIG. 1, and the forward tilt angle of the legs can be increased. Moreover, if the locking part 14a is engaged with the positioning engagement part 17 and the band body 9 is tightened, the forward leaning posture including the legs becomes as shown by the dashed line in FIG. It can be adjusted even more than in the case of the dotted chain line.

Next, the case of adjusting the anteversion pressure will be described.

In this case, first loosen the band body 9 and disengage the locking part 14c from the engaging part 17, and then attach the end of the band body 9 having the buckle 12 to its engaging protrusion 11 as shown in FIG. is rotated in the direction of arrow A using the locking part 13 as a fulcrum, and with the locking part 13 disengaged from the engaging part 15, it is slid up and down along the elongated hole 16 in the direction of arrow B. As a result, both locking portions 13 of the band body 9
And the engaging position of the positioning engaging parts 15 and 17 of the locking parts 14c (or the locking parts 14a, 14b) is changed up and down. For example, if the tightening position of the band body 9 with respect to the upper shells 4a and 4b is moved as shown in the two-dot chain line or the one-dot chain line in FIG. The distance between the two becomes shorter, and the amount of opening of the upper part of the shell relative to the heel increases, creating a feeling of pressure when leaning forward. It becomes soft.
That is, the forward tilting pressure can be adjusted by vertically changing the tightening position relative to the upper shell.

(F) Effect of the invention As explained above, according to this invention, a plurality of positioning engagement parts for setting forward tilting pressure are formed in the vertical direction on the outer surface of the outer upper shell. , and the upper shell tightening band body is provided with a locking part that engages with the positioning engagement part, and the band body is wrapped around the outer circumference of the upper shell to set the locking part at a desired position of the positioning engagement part. After that, all you have to do is lock the free end of the band body to the buckle attached to one end of the band body and tighten it, so operations for tightening the upper part of the ski boot and adjusting the forward tilt pressure can be done with one touch. , even skiers who are inexperienced with these operations can use them easily and with peace of mind.
