Abstract

PURPOSE: To regulate the pushing pressure exerted on the front part of a foot and a forward inclination function of the upper shell by installing a clasp as a binding fixture means of a ski boot on an upper shell and by having such a structure that an upper shell is linked to an outer boot shell by a hinge and that on both sides of the upper shell a pair of branch segments extending the toe are formed. CONSTITUTION: An upper shell 2 is linked to an outer boot shell 4 by a hinge 15, forming a pair of branch segments 3 extending toward the toe on both sides of the upper shell 2, and is equipped with clasps of binding fixture means 7, 8 & 9. A forward inclination is performed by the upper shell 2 and the hinge 15 acts as a rotational point. The two tip portion of two of branches segments 3 incline toward the sole. When a tongue section 6 of a ski boot is completely fastened to the upper shell 2, the movement of two branches segments 3 is utilized to apply pushing pressure not only to the tongue section 6 but also to the instep.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The invention relates to a shell-type ski boot, in particular an outer boot shell with an integrated sole, a tiltable upper shell, a tongue and a tightening A ski boot with fastening means and an inner boot.

[Conventional technology]

During so-called alpine skiing, especially during competitions,
In order to guide the ski in the positive direction, it is necessary to press the ski boot snugly against the foot. When such a pressing force is applied for a certain amount of time,
This pressure can be uncomfortable and cause foot pain. As a result, ski competitors, particularly slalom competitors, typically tighten their boots before a competition and then loosen them again immediately after the competition to reduce the pressing force.

It has been found that a large pressing force of 2 is required only in the pressing phase of rotation.

OBJECTS OF THE INVENTION The object of the invention is to provide a ski boot that adjusts the pressing force on the front part of the foot and the forward tilting function of the upper shell.

[Means to solve the problem]

To this end, in a shell-type ski-boo according to the invention of the type mentioned at the outset, the upper shell is connected by a hinge to the outer boot shell, extending on both sides of the upper shell towards the toe of the boot and forming a forked branch. The fastening of the tightening means of the ski boot is arranged substantially on the upper shell, so that the pressing force exerted by the tongue on the instep of the foot is dependent on the tilting moment of the upper shell.

[Operation and effects of the invention]

In the shell-type ski boot according to the invention, the upper shell extends forward from the lateral elbows on each side of the boot and forms forks, as described above. Forward tilting is performed by the upper shell. A hinge near the ankle acts as a pivot point. The two tips of the fork perform a tilting motion towards the sole. When the tongue of the ski boot is completely fixed to the upper shell, the movement of the forks is used to apply a pressing force to the tongue and thus to the top of the foot. This provides optimal support within the boot when the skier requires pressing force.

This allows a very positive guidance of the ski whenever required.

In such ski boots, the stop location on the rear side of the tilting upper shell can likewise be made variable.

In the toe position, the upper shell is typically tilted slightly forward with respect to the vertical. If the stop is adjusted in such a way that a rearward tilting of the upper shell is possible beyond the vertical line, the skier can walk more comfortably, since there is no pressing force on the foot. Such a position is a walking setting. Converting gait setting to ski setting is possible even while skiing if necessary.
It can be done very simply. This backwardly sloping position reduces the pressing force on the front part of the foot. Therefore, skiing can be done with less fatigue.

This is because the pressing force is applied to the foot only when the ski condition requires it.

The pressing force applied to the instep of the foot can be varied by selecting the distance from the hinge to the point of action of the fork.

If this point of action is in the front, the force applied to the front part of the foot due to lever action will be greater.

Various tongue devices can be used in the ski boots of the present invention. For example, it is possible to use an outer tongue that is pressed against the foot by means of a common buckling device. However, unlike traditional ski boots, this buckle device is completely fixed to the upper shell. The outer boot tongue is not necessary if the inner boot tongue is sufficiently stable. This tongue can be suitably placed on the foot, for example, by means of an arcuate member forming part of the clamping means.

〔Example〕

Preferred embodiments of the invention will now be described in detail with reference to the accompanying drawings.

In FIG. 1, the ski boot 1 is shown with the elements of the inner boot omitted. Boots 1 have a forward tilt position of 2a.
and a tiltable upper shell 2 whose rearward tilted position is indicated by 2b, and the front end 3 of the forked arm of this upper shell 2.
(designated 3a and 3b, respectively), an outer boot shell 4, an integrated sole 5, and an inner boot shell 1.
8 or a tongue 6 which can be provided in conjunction with the outer boot shell 4.

The connection of the tongue arch 7 to the tongue 6 takes place by means of an attachment band 8 . By adjusting this attachment band, an appropriate pressing force can be applied. The central buckle 9 includes a hook inserted into a notch 10 in the arcuate member 7 and a pivot pin 1l. This pivot pin also serves to attach the buckle 9 to the upper shield 2. Element 12.1
3 forms a device allowing adjustment of the upper shell 2 for walking or skiing setting.

In case of ski setting, only a movement of the upper shell 2 into position 2a is possible, the lever 14 being snapped between elements 12 and 13. If the lever 14 is rotated outward, the upper shell 2 will tilt back to position '77'lb. This allows the skier to walk comfortably while at the same time reducing the pressure on the legs. In the tilted state, the upper shell 2 rotates about the hinge l5. The tongue arch 7 can be fixed to the outer boot shell 4 by means of a mounting hole 16. Instead, the arcuate member 7
Alternatively, the entire tongue 6 may be fixed to the lateral hinge joint of the upper shell.

FIG. 2 is a perspective view of the ski boot according to the invention, seen from the side opposite the buckle. In FIG. 2, the outer boule shell 4, the upper shell 2 and the tongue arch 7 are shown, with the tongue eye being omitted. Reference numbers correspond to those in FIG. The arcuate member 7 is inserted into and held by the hook 17. By opening the buckle 9 (not visible in FIG. 2), the arcuate member 7 can be easily removed from the hook 17.

The above-described embodiments of tongues with tongue arches are only preferred embodiments; other fastening means and tongues can be used without departing from the basic idea of the invention.
