Description

[Detailed explanation of the invention] (a) Technical field of the invention This invention relates to ski boots, and more specifically, this invention uses a band and a fastener to tighten the upper shell part corresponding to the ankle to improve the forward tilt angle and the forward tilt angle. This invention relates to the improvement of ski boots that can adjust the pressure.

(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, in addition to the tightening mechanism that tightens the upper part of the shell, there is also a forward tilting angle adjustment mechanism for the boots to maintain an ideal forward leaning posture that does not fatigue the leg muscles, and a forward tilting pressure that determines how soft or hard the boots can be tilted forward. The technology for providing each adjustment function is well known and was developed in Japanese Patent Application Publication No.
This method is known from Japanese Patent No. 52-138246.

The conventional ski boot tightening mechanism described above has a plurality of locking holes circumferentially formed on both the left and right sides of the upper flap of the ski boot, and two locations of the tightening collar are positioned in one of the locking holes using a stopper. fixed,
By tightening the free end of the collar that is inserted into the rear support of the upper part of the ski boot with a buckle connected to the fixed end of the corresponding collar, a predetermined stiffness (forward tilting pressure) is given to the upper part of the ski boot, In addition, the forward inclination angle of the upper part of the ski boot relative to the bottom surface is changed.

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, 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. Furthermore, there were other problems such as the inability to finely adjust the angle of forward inclination with respect to the bottom surface of the upper part of the ski boot, and the forward inclination angle to suit the legs of each skier cannot be adjusted unless the collar is changed.

(C) Purpose of the invention This invention was made to solve the conventional problems as mentioned above. The purpose of the present invention is to provide ski shoes that enable the setting of an optimal forward inclination angle to suit the user's needs, and that even inexperienced skiers can use them with confidence.

(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 the lower shell, and An inner boot inserted into the shell 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 wrapped around the outer periphery of the outer and inner upper shells and both cuffs. a pair of band bodies that can be engaged and separated; an engaging part provided at each end of the pair of band bodies; and a pair of engaged band bodies provided on one of the band bodies. a clamp lever formed on the outer and inner upper shells to restrain movement in the circumferential direction of the pair of band bodies, and a clamping force that connects both ends of the pair of coupled band bodies. It is composed of a buckle that gives a

(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 shoe equipped with a tightening mechanism that can adjust the forward tilt angle and forward tilt pressure according to this invention. This shell body 1 is composed 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. Upper shell 4a, 4b by cuff 5 and rear cuff 6
The lower ends of the front cuff 5 and the rear cuff 6 are pivotally connected to the lower shell 3 so as to be tiltable in the front-rear direction.
When inserting the foot into the ski boot, both the cuffs 5,
6 can be tilted outward and expanded 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 1 and the skier's feet in order to fit the skier's feet within the shell body 1; 8 is the upper shell 4a, 4b; , a band body that tightens the upper outer circumferences of the front cuff 5 and the rear cuff 6, and 9 a buckle that applies a tightening force to the band body 8. This buckle 9 includes a frame body 9a rotatably attached to one end of the band body 8, and a serrated frame body rotatably pivoted within the frame body 9a and formed on the outer surface of the other end of the band body 8. It is composed of a claw member 9b that engages with the uneven portion 10. In addition, the band body 8 can be adjusted by adjusting the band length on the front cuff 5 side, where movement in the circumferential direction is restricted by the outer and inner upper shells 4a and 4b. and a forward tilting pressure adjustment mechanism 12 that adjusts the forward tilting pressure of the legs by adjusting the vertical tightening position of the upper part of the shell body 1 by the band body 8. We are prepared.

The forward tilt angle adjustment mechanism 11 has separable overlapping parts 8a and 8b for adjusting the band length on the front cuff 5 side of the band body 8, and the mutual joint surfaces of the overlapping parts 8a and 8b are As shown in FIGS. 5 and 6, a large number of joining spline grooves 13 and 14 that engage with each other are formed in the length direction, and a pair of connecting protrusions 15a are formed on the surface on the spline groove 14 side. , 15b are formed, and a pair of elongated holes 1 into which the connecting protrusions 15a, 15b fit are formed in the overlapping portion 8b.
6a, 16b are formed in the longitudinal direction, and a base portion of a clamp lever 18 is rotatably attached to the connecting protrusions 15a, 15b by a shaft pin 17. The pivoting base of the clamp lever 18 has an overlapping portion 8b and an overlapping portion 8a.
A cam 18a is formed that presses against and connects the two.

The forward tilting pressure adjustment mechanism 12 also includes a frame member 20 inserted into a vertically long recess 19 formed on the outer surface of the inner upper shell 4a of the shell main body 1, as shown in FIGS. 3 and 7. , a screw member 21 with a reuse 21a rotatably supported within the frame member 20, and a screw member 21 with a reuse 21a, which is threadedly engaged with the screw member 21 and is vertically movably engaged within the frame member 20, and the band The movable member 22 is integrally fixed to the inner surface of the body 8 on the buckle 9 side.

23 is an overlapping portion 8b of the band body 8
This locking portion 23 is formed on the inner surface of the side.
It is slidable up and down in a vertically elongated recess 24 formed on the outer surface of the outer upper shell 4b of the shell main body 1, and is engaged in a circumferential direction with a rotation stopper.

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

When attaching ski boots to a skier's feet in a fitted state, first tilt the front cuff 5 and rear cuff 6 to the position shown by the two-dot chain line in Fig. 4, insert the foot into the inner boot 7, and then The cuff 5 and rear cuff 6 are set approximately as shown by the solid lines in FIG. After that, the band length on the front cuff 5 side is set by adjusting the overlapping amount of the overlap portions 8a and 8b according to the thickness of the skier's ankles and the desired forward tilt angle, and the clamp lever 1
8 is set as shown by the solid line in FIG. 5, and the overlapping portions 8a and 8b are connected to each other.
is wound around the outer circumferences of the upper shells 4a, 4b and the cuffs 5, 6, and the locking portion 32 thereof is engaged in the recess 24 of the upper shell 4b. In this state, the end of the band body 8 on the side of the concavo-convex portion 10 is inserted into the buckle 9, and after the claw member 9b is engaged with the concave-convex portion 10, the buckle frame body 9a is tilted in the tightening direction. Then, due to the tightening force of the band body 8, the upper shell 4a, including the cuffs 5 and 6,
The entire part 4b is tightened in the direction of contraction. At this time, the overlap side band portion facing the front cuff 5 side between the locking portion 23 and the forward tilting pressure adjustment mechanism 12 is formed by the locking portion 23 and the frame member 20 that engage in the respective recesses 24 and 19. Since the band portion is restrained by the buckle 9, even if a tightening force is applied to the band body 8 by the buckle 9, almost no displacement occurs in the direction of the arrow in FIG.
A tightening displacement occurs in the band portion on the 0 side in the direction of the arrow in FIG. For this reason, the rear cuff 6 side is narrowed inward due to the tightening displacement, which causes the entire inner boot 7 including the rear cuff 6 to be squeezed into the upper shell 4.
Push it toward the front cuff 5 side using a and 4b as reference points. 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 vertical position of the band body 8 by the forward tilting pressure adjustment mechanism 12.

On the other hand, if you want 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. Operate the lever 18 from the state shown by the solid line in FIG. 5 to the state shown by the two-dot chain line to release the clamping force on the overlapped parts 8a and 8b, and move the overlapped part 8a or 8b in the direction of arrow B or C in FIG. In this manner, the amount of overlap between the two overlapping portions 8a and 8b is adjusted. That is, if the amount of overlap between the two overlapping portions 8a and 8b is increased, the band length between the locking portion 23 on the front cuff 5 side and the frame member 20 (or the screw member 21) becomes shorter, and the overlapping portions 8a and 8b become shorter.
If the amount of overlap between and 8b is reduced, the band length becomes longer.

Therefore, if the upper outer periphery of the shell main body 1 is tightened with the band body 8 in which the overlapping amount L between the two overlapping parts 8a and 8b is smaller than that in the case shown in FIG. 5, the front cuff 5 including the legs, the rear cuff 6, and the inner boot The forward leaning posture of No. 7 is the state shown in the dashed line in FIG. 1, and the forward leaning angle of the legs can be increased. Also,
If the upper part of the shell body 1 is tightened with the band body 8 in which the overlapping amount L between the overlapping portions 8a and 8b is smaller than in the above case, the forward leaning posture including the legs will be as shown by the two-dot chain line in FIG. Therefore, the forward inclination angle can be adjusted to a greater degree than in the case of the dashed line.

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

In this case, with the buckle 9 open, the screw member 21 of the forward tilting pressure adjustment mechanism 12 is rotated by its use 21a to slide the movable member 22 in the direction of arrow A in FIG. If the band body 8 is tightened by moving to the position shown by the one-dot chain line or the two-dot chain line in Figure 1, the distance from the ankle, which is the branch point when leaning forward, to the ankle, which is the point of action, will be shortened, and the upper part of the shell relative to the ankle will be shortened. The amount of release increases, and the feeling of pressure when leaning forward becomes softer. That is, the forward tilting pressure can be adjusted by vertically changing the tightening position of the band body 8 relative to the upper shell.

Note that the forward tilt angle adjustment mechanism 11 in the present invention
is not limited to the structure shown in the above example,
In short, the outer and inner upper shell 4 of the shell main body 1
Any type can be used as long as the length of the band on the front cuff 5 side that is restrained by a and 4b can be adjusted. Also,
The connecting protrusions 15a and 15b may be formed integrally with the overlapping portion of the band body 8, or may be formed separately by inserting a concave metal fitting.

(f) Effect of the device As explained above, according to this device, the band body with a buckle tightens the upper outer periphery corresponding to the ankle portion of the shell body, and the movement in the circumferential direction is restrained by the outer and inner upper shells of the shell body. Since it is equipped with a forward tilt angle adjustment mechanism that adjusts the forward tilt angle with respect to the leg by adjusting the front side band length, the forward tilt angle can be adjusted over a wide range and can also be finely adjusted. In addition to being able to adjust the forward lean angle to suit each individual, even skiers who are inexperienced with these operations can use it easily and with confidence.
