Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a foot stabilizing device, and particularly to a foot stabilizing device used in ski boots having a hard body, a rear waist strap, and a front waist strap. Regarding.

BACKGROUND OF THE INVENTION Modern ski boots, especially in the inner heel area of the rigid body, are equipped with devices to properly stabilize the skier's foot and to ensure optimal transmission of forces from the foot to the ski. , is extremely important.

Several types of devices are known that have been devised for this purpose, some of which are rotatably attached to the back of the rear waistband of the shoe and have a screw-shaped handle located inside the waistband. At the end of the shoe, the shoe is characterized by an arrangement including a tab with a presser that interacts with a flap projecting from the shoe body.

In this conventional device, actuation of the knob creates a pressure point concentrated in a very small area of the flap, so the device is not compatible with the varying heel geometry and does not allow the shoe to be worn for long periods of time. If used, it may cause heel pain.

As a partial solution to these problems, the applicant has:
Italian Patent Application No. 2 filed on July 23, 585
2578 B/85, an elongated element extending across the longitudinal extension of the rear waist of a shoe, located inside the rear waist at approximately the location of the user's heel and opposite the rear waist. A ski boot is disclosed having features including an elongated element connecting the side longitudinal edges.

However, even this apparently effective device suffers from problems due to the fact that it deforms the hem of the rear waistband when subjected to stress, especially during those flexing steps where reliable foot stability is most needed. This resulted in a decrease in the degree of stability.

It also consists of a threaded rod that can be operated by the skier, and the pawls are rotatably connected.
Some devices are known in which the pawl has a sloped surface that interacts with a complementary sloped surface of a presser or flap arranged behind the heel.

For example, Italian Patent Application No. 22789 B/81 filed on August 31, 1981 by the present applicant;
French Patent Application Publication No. 25 filed on August 10, 2013
No. 47208 discloses a ski boot equipped with a device of this type.

However, although these conventional devices provide reliable stabilization of the heel area, they suffer from the problem that they do not optimally stabilize the foot within the shoe.

OBJECTS OF THE INVENTION It is therefore an object of the present invention to provide a device that achieves optimal stability of the foot in the heel area and inside the shoe, thus solving the above-mentioned problems of the prior art. It is in.

One of the important objects within the scope of the above-mentioned objects is to provide a device in which optimum stability of the heel of the foot is achieved by a rotational actuation.

Another important objective is to provide a device that is simple in construction, yet reliable and safe in use.

A further object, in addition to the above-mentioned features, is to provide a stabilizing device which allows the foot to be removed from the shoe in such a way that the degree of stability achieved when the shoe is put on again is unchanged.

(Means for solving the problem) The goals mentioned above and the objectives clarified below are:
1. A stabilizing device for a ski boot having a rigid body, a front waist strap and a rear waist strap, the device comprising: a threaded rod; a threaded pawl engaged with the rod; a presser, the pawl having an inclined surface adapted to engage an inclined surface on the first presser, the rod having a longitudinal axis, and the pawl having a longitudinal axis upon rotation of the rod. an apparatus movable along the longitudinal axis for moving the first breather in a direction substantially perpendicular to the longitudinal axis, the apparatus including at least one tensioning element connected at one end to the pawl; This is achieved by means of a foot stabilizer which surrounds the instep of the foot.

Preferably, said prefusor is constituted by a rear flap that connects to the stiff part of the shoe or to the inner shoe.

(Operation) In the present invention, when the eccentric lever 10 is actuated, the movement is transmitted to the pawl 14, and this causes the interaction between the tension of the cable 18 and the inclined surface 15 of the pawl 14 and the inclined surface 16 of the flap 17. A clamp-like tightening of the skier is obtained by causing a heel-directed movement of the flap 17 by the heel, and the combination of the tension of the cable 18 and the flap movement results in an optimal stabilization of the foot inside the shoe. In addition, it is possible to open the waist leather part, especially the rear waist leather 3, which is locked by the cable under tension at the sheath 20 between the guide 19 connected to the rear waist leather 2 and the guide 21 connected to the main body 3, and further To release the foot, the lever is simply reversed into the open position shown in solid line in FIG. The device "remembers" the selected tightening strength and simply flips the lever 10 back to the tightened position to obtain the previously selected degree of tightening.

Further features and advantages of the invention will become apparent from the detailed description of non-limiting embodiments illustrated in the accompanying drawings.

(Example) In each figure, the reference numeral 1 indicates a front waist strap of a ski boot that is connected to a rear waist strap 2 and a rigid main body 3.

The device includes a threaded rod 4 adjoining the rear waistband 2 and disposed there transversely just before the back surface 5.

The threaded rod 4 is rotatably connected at its first end 6 with a matching seat 7 provided on a lug 8 projecting inside the rear waistband 2.

A second end 9 of the threaded rod 4 projects laterally outward from the rear waistband 2, and an eccentric lever 10 that can be operated by a skier is rotatably connected to the second end 9.

Upon actuation of the eccentric lever, the threaded rod 4 is thus able to move along its axis, with its first end 6 rearwardly disposed in the seat 7, preferably coaxially, with the second end 9. It is biased by a spring 11 arranged between the inner surface 12 of the waistband 2 and an annular flange 13 provided on the threaded rod 4 near the second end 9.

The eccentric lever 10 specifies two positions. In the open state shown in FIG. 1, the end 6 of the rod 4 is fully inserted into the seat 7, and the dotted line In the stable position shown in the figure, the rod 4 is to the right in the figure,
It has moved by a distance corresponding to a degree of eccentricity of 0.

A threaded lug 14 is connected to the threaded rod 4,
On its side facing the foot, it has an inclined plane 15.

The pawl 14 cannot rotate and only rotates along the axis of the rod 4 when the rod 4 rotates.

The inclined f plane 15 has a main body or inner v11 at the heel of the foot.
, 3 is engaged with the inclined surface IB provided on the rear presser or flap 17.

#i On the opposite side of the oblique surface 5, the end of at least one tensioning element is connected with a pawl 14, said tensioning element extending on the side opposite the eccentric lever 10 and connecting with the inner surface 12 of the rear waistband 2. The sheath 20 is guided by the first guide 18 that is connected to the chamber and reaches the second guide 21 that is connected to the main body 3.
It is partially enclosed by a cable 18.

After passing through the second guide, the four cables 18 pass through a first hole 22 provided in the lateral direction of the body 3 and have a portion 23 that surrounds the preflexor 26 in the area of the instep of the foot, and extends in the lateral direction of the body 3. It exits the body through a second hole 25 provided in the main body and is fixed by a rivet 24 provided in a matching manner.

The use of this device is as follows. Eccentric lever 10
When actuated, a movement is transmitted to the pawl 14, which causes a movement of the flap 17 towards the heel due to the tension on the cable 18 and the interaction between the inclined plane 15 of the pawl 14 and the inclined plane I6 of the flap 17. cause both.

Clamp-type tightening of the skier's foot is thus obtained, and in order to achieve the best possible stability, the eccentric lever 1
It can be adjusted by rotating 0.

A sheath 20 between a guide I9 connected to the rear waist leather 2 and a guide 21 connected to the main body 3 can open the waist leather part, especially the rear waist leather 3, which is locked by the tensioned cable.

In FIG. 1, the tightened state of the lever 10 is shown in dotted lines, and in order to release the foot, the lever 10 can be opened without rotating the rod 4 in order to move the pawl 14 relative to the rod 4.・Just flip the bar to the open position shown by the solid line in the figure. In this way, the device memorizes the selected tightening strength. In fact, in order to obtain the previously selected degree 1) of the tightening condition, the lever 10 need only be tightened 17) by simply inverting it back to the position indicated by the dotted line thW'lc.

It is therefore believed that the present invention achieves the intended goals and objectives of Mo. 11 by providing a device for optimally stabilizing the foot inside the shoe by a combination of tension and flap action of the cable clamping the .

The device is also easy and quick to adapt to the specific needs of each skier and is extremely simple in construction.

Furthermore, the configuration of the device is such that the rear waistband is moved rearward, thereby allowing for easy foot removal and heel release, and the device "remembers" the selected degree of tightness; The degree of tightening is 311 each time! This allows the waistband to be opened and closed without the need for li.
