Description

[Detailed explanation of the invention] (a) Technical field of the invention This invention relates to ski boots, and more specifically, the forward inclination angle 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 ski and improve the operability of the ski when skiing, the upper part of the shell corresponding to the ankle is tightened with a tightening device, or the instep of the foot is held in place. It is designed to provide a more secure ankle fit.

In addition, a technique is known in which the tightening mechanism that tightens the upper part of the shell has a function of adjusting the forward tilt angle of the boots to maintain an ideal forward tilted posture that does not fatigue the leg muscles. etc. is known.

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 positioned and fixed and wrapped around the rear support of the upper part of the ski boot, by a buckle engaged with the corresponding fixed end of the collar, the angle of forward inclination of the upper part of the ski boot with respect to the bottom surface is adjusted. It's starting to change.

However, the conventional tightening mechanism described above, when positioning and fixing the collar to the upper part of the ski boot,
Since a stopper is used that is separate from the upper part and the collar, it is complicated to change the position of the locking hole in the collar, 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 with changing the collar stop position cannot do so without taking their feet out of their 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 also 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 position of the tightening band in the circumferential direction with respect to the upper shell of the boot with a single touch when adjusting the forward tilt angle. 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 and inner upper shells, and positioning parts formed on the outer surfaces of the outer and inner upper shells, respectively. an engaging part, a band body wrapped around the outer periphery of the upper shell and both cuffs, a locking part formed on an inner surface of one end of the band body and engaging with a positioning engaging part of the outer upper shell, and the band. a plurality of forward tilt angle setting locking portions formed along the longitudinal direction of the inner surface of the intermediate portion of the body and engaging with the positioning engaging portions of the inner upper shell, and attached to one end of the band body; It consists of a tightening buckle that locks the free end of the band member.

(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 that can adjust the forward tilt angle 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 covering the foot part, and outer and inner upper shells 4a and 4b covering 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. 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. ciel 3
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 for setting the forward inclination angle of the leg.

As shown in FIG. 4, the tightening mechanism 8 has a band-like 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. A protrusion 10 is formed on the band body 9, and an engagement protrusion 11 for connecting to the outer upper shell 4a is integrally formed at the other end of the band member 9, and protrudes inwardly. A buckle 12 for tightening the upper shell portion is integrally attached, and this buckle 12 is attached to a frame 12a rotatably attached to one end of the band main body 9, and a frame 12a rotatably attached to the frame 12a. A claw member 12b is attached to the band member 9 and is engaged with the concavity and convexity 10 of the band body 9. A convex locking portion 13 is formed on the inner surface of the other end of the band body 9 for positioning the band body 9 with respect to the outer upper shell 4a, and a convex locking portion 13 is formed on the inner surface of the intermediate portion of the band body 9. are convex locking portions 14a, 14 that set the forward inclination angle of the legs with respect to the bottom portion 2 of the shell body 1;
b, 14c are formed in a plurality of rows, ie, 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.

As shown in FIG. 6, the outer upper shell 4a is formed with a concave positioning engagement part 15 that engages the engagement part 13 of the band body 9. An elongated hole 16 is formed in which the engagement protrusion 11 of the band body 9 engages to prevent it from coming off. Further, as shown in FIGS. 5 and 7, a concave positioning engagement portion 17 is formed on the outer surface of the inner upper shell 4b so as to face the engagement portion 15 of the outer upper shell 4a. The joining part 17 has a locking part 14a for setting the forward tilt angle of the band body 9.
14c is adapted to be engaged.

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

When the ski boots are attached to the skier's legs in a tight state, first, the engagement 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.
, one end of the locking portion 13 is engaged with the positioning engagement portion 15, and one of the locking portions 14a to 14b on the other side, for example, the locking portion 14c as shown in FIG. The positioning engagement portion 17 is engaged. In this state, attach the free end of the band body 9 to the buckle 1.
2, and after locking the claw member 12b to the concavo-convex portion 10, the buckle frame body 12a is tilted in the tightening direction. Then, the entire upper shells 4a, 4b including the cuffs 5, 6 are tightened by the tightening force of the band body 9. 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 7 and the band body 9 is tightened, the forward leaning posture including the legs becomes as shown by the dashed line in FIG.
The forward tilt angle can be adjusted to a greater degree than in the case of the two-dot chain line.

In the above embodiment, the engagement protrusion 1 of the band body 9
1 is inserted and engaged into the elongated hole 16 of the outer upper shell 4a, and the one end side locking part 13 of the band body 9 is engaged with the positioning engagement part 15. may be fixed to the outer upper shell 4a.

(f) Effect of the device As explained above, according to this device, positioning engagement portions are formed on the outer surface of the outer shell body and the outer surface of the inner upper shell, and the outer upper shell is formed at one end of the upper shell tightening band body. A locking portion that engages with the positioning engagement portion of the shell is provided, and a plurality of locking portions that engage with the positioning engagement portion of the inner upper shell are provided in the middle portion of the band body along the longitudinal direction of the band body. , after wrapping the band body around the outer circumference of the upper shell and setting one of the forward tilt angle setting locking parts to the corresponding positioning engagement part, attach the free end of the band body to one end of the band body. Because all you have to do is lock and tighten the attached buckle, operations for tightening the upper part of the ski boot and adjusting the forward tilt angle can be performed with a single touch, and even skiers who are unfamiliar with these operations can use it easily and with confidence. can.
