Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to ski boots, and particularly to ski boots for skiers.
'! The present invention relates to a ski boot having an upper waistband connected to a front waistband to dampen the impact between the bone and the waistband of the boot.

(Prior art and its problems) As is well known, in ski boots, the waist leather can swing around a water axis that extends perpendicularly to the longitudinal direction of the bottom of the shell. connected to the shell.

Ski boots generally have very limited flexibility;
It has a point that defines the limit of rocking, and this causes the waistband to be unable to continue rotating, causing skiers to
There may be a collision between the leg and the waist leather of the boot.

The impact between the skier's legs and the boot's waistband can be a nuisance to the boot wearer, especially after long periods of use.

Applicant's earlier U.S. Pat. No. 4,811,415 includes:
A device for adjusting the flexibility of ski boots is described, in which the waist leather not only allows adjustment of the flexibility of the waist leather within the range consisting of the leg and waist leather. It is connected to the shell via an elastic washer that also acts to dampen collisions with the shell.

However, with this device the damping effect is only secondary to the structure of the boot and is therefore not optimal.

French patent application No. 81.10671 describes a ski boot with a notch in the upper edge of the front waistband, in which the notch covers the notch and in its central part the waistband A distribution plate or curved plate is arranged which is pivoted around an axis extending transversely to the longitudinal direction and supported by the waistband itself.

This plate is located in the area on which the tibia of the leg rests, always keeping the angular orientation of the skier's leg constant and creating a distributed support area that is not concentrated at the edge line.

At least most of the sides of this plate exist inside the waist leather and exert a rubbing action on the waist leather itself, and therefore,
011 Leather has a unique elasticity that depends on the material, so
This causes an elastic biasing action, which is approximately dependent on the degree of movement due to the bending, and which tends to move the plate towards its initial rest position.

Therefore, since the elasticity is determined only by the rubbing action between the plate and the waist leather and the material of the waist leather, it has been found that the above configuration is not very practical because it is significantly influenced by external factors such as temperature. Ta.

It is therefore an object of the present invention to achieve the above-mentioned ski boots by providing a ski boot that is capable of elastically damping the collision between the leg and the waist leather without affecting the selectable flexibility of the r* leather. It's about solving problems.

Among the above objects, one object of the present invention is to provide a ski boot that is extremely comfortable for the skier and is capable of elastically absorbing collisions between the skier's legs and the waistband of the boot.

Another object of the invention is to provide a ski boot that does not require complex construction of the ski boot itself in order to provide shock absorption or damping properties.

A further object of the invention is to provide a ski boot which is easy to manufacture and which is advantageous from a purely economic point of view.

(Means for Solving the Problems) The problems, goals, and objectives mentioned in E and other objects that will become clear below are solved by providing a shell in which a front waist strap and a rear waist strap are connected, according to the present invention. A ski boot comprising: an upper waist strap pivotally attached to the front waist strap and located at least partially in an area below the front upper edge of the front waist strap; This is achieved in a ski boot characterized in that it is provided with means for connecting the leather to the rear waist leather.

Other features and advantages of the invention will become apparent from the following description of preferred, but not exclusive, embodiments, which are illustrated in a non-limiting manner in the accompanying drawings, in which: FIG.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the accompanying drawings, in particular with reference to FIG. 1, a ski boot according to the invention comprises a shell 1 in which a front waistband 2 and a rear waistband 3 are connected in a manner known per se. ing.

The peculiarity of the invention lies in the provision of an upper waistband 10 located approximately in the lower region 11 of the front upper edge of the front waistband 2.

The upper waist strap 10 is swingable with respect to the front waist strap 2, and is hinged by a bin 12 or the like located at the front of the waist strap or by a side hinge connection provided at the lower part of the upper waist strap 10. be able to.

The E section waist strap 10 is also connected to the front waist strap 2 by a peg 15, which is suitably fixed to a lateral position of the front waist strap 2 and correspondingly defined on the upper waist strap. is engaged with the elongated slot 1B.

In this configuration, the peg 15 is slidably held in the slot 16, and since the peg is fixed in a lateral position on the front waistband 2, the slot has a sliding movement relative to the peg.

The upper waistband lO cooperates by articulation means consisting of a cable 20 with an operating lever 21 which is fixed to the front waistband and can be operated to apply the desired tension to the cable.

This cable, which actually acts as a tensile upper member, can be connected to any point on the upper waist, and the upper waist can be located on the inside or outside of the front waist. can be done. If the upper waist strap is located on the outside, the cable will pass through the outside of the front waist strap.

During bending, the upper waistband rotates forward, but the limit is determined by the length of the slot 16. At zero rotation, the upper waistband is connected in advance, so the rear waistband, which is connected by the cable 20, rotates forward. The leather also moves forward.

In this case, the shock-absorbing or shock-damping effect is actually obtained by utilizing the forward bending of the rear waistband, which is pulled by the cable.

The elastic return of the upper waist leather released from the weight of the bent wearer's legs is achieved by the elastic return of the rear waist leather to its original resting position.

With this configuration, when bending forward, a load is applied elastically to the rear waistband, so that the leg is evenly surrounded when bending forward.

In another embodiment of the invention shown in FIGS. 2 to 5, the upper waistband lO cooperates with the front waistband 2 in its upper part by a boss or pin 25, which pin are secured to the sides of the front waistband and engage holes or openings 26 defined in the thickness of the top waistband IO. Second
Corresponding parts are provided with the same reference numerals in the figures.

This opening 26 is provided with elastic shock absorbing means advantageously constituted by a sector 31 of elastic material, such as rubber, acting between the front waistband and the top waistband, which sector is connected to the opening 2B. It is accommodated in the upper waist strap 10 and remains within the thick part of the upper waist strap 10 to engage with the boss 25.

The relationship between the elastic fan-shaped members 31 is as follows.

That is, when the leg bends forward and presses the upper waist strap, the upper waist strap 10 rotates around the bin 12 with respect to the front waist strap 2, and as a result, the fan-shaped member 31 is compressed on the boss 25. shock is elastically absorbed.

As soon as the impact ceases, the upper waistband elastically returns to its initial position due to the elastic expansion of the sector 31 which biases the upper waistband to its initial position.

The sector 31 forms a semi-circular portion and is advantageously arranged to engage the portion of the boss 25 facing the rear waistband.

From the foregoing description, it can be seen that the present invention fully achieves its foregoing goals and objectives. In particular, two aspects of the present invention include the above al.
l [between the tibia and the front waistband by utilizing elastic means, which can be constructed by the inherent elasticity of the front waistband connected to the leather or by an elastic fan-shaped member housed in the hole 26; This gives the possibility of attenuating the impact caused by forward bending.

The present invention is susceptible to various modifications and changes within the inventive concept.

Note that all members can be replaced with other technically equivalent members.

Practically speaking, any size and shape of the material may be employed as required.
