DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for adjusting the position of a leg relative to a shell of a sports shoe.

[0002]

2. Description of the Related Art A conventional ski boot has a shell, and at least one leg (quarter) is articulated near an ankle region of the shell. Therefore, the leg can be rocked back and forth during the sports exercise. One of the problems encountered when using ski boots is to control the swinging of the legs in response to the sports exercise being performed, and to be able to walk once the boots have been removed from the skis and bindings. The object of the present invention is to control the swing of the leg in response to a request from the user to do so.

[0003] The ski boot disclosed in DE 1,932,776 has one leg, behind which an elongated oval strip projects towards the shell. The strip has an axially formed seat having three distinct areas. Then, the stem of the screw can be selectively positioned in three regions. The screw is rotatably associated with a plate rigidly connected to the rear of the shell.

[0004] Thus, this solution allows the legs to be forcibly inclined relative to the shell. However, the selection position is fixed. Also, since the screws are in specific positions, special tools must be used and the ski boot must be taken off for position selection. For this reason, the stem of the screw cannot be easily positioned so that the leg can swing. Also, since the stem is rotatable, undesired jamming of the stem may occur, causing the strip to deform. In this case, ski boots cannot be used.

[0005] In each case, the skier must directly bias the screw. The skier must rotate the stem until the screw re-engages with the desired seat after disengagement. The ski boot disclosed in U.S. Pat. No. 3,543,421 has a shell with legs articulated on the sides of the shell. The leg has a bar in the rear region, which is pivotally pivoted transversely to the leg.

[0006] The stem of the positioning portion is rotatably associated with one end of the bar and is in contact with the plate.
The plate is longitudinally associated near the lower shell. This solution can change the inclination of the legs. However, if the leg rests on the leg and strong friction occurs between the positioning portion and the plate, it is difficult to release the engagement between the positioning portion and the plate to change the inclination.

[0007] The ski boot disclosed in French Patent No. 2,020,726 comprises a shell, to which the legs are associated. In the rear region, a flexible flap is associated with the leg. The flap has teeth facing the opposite shell side. The teeth are selectively positionable in one of a longitudinally formed seat or one of a plurality of separate seats with respect to a plate rigidly connected to the rear of the shell.

However, even this solution has drawbacks. First, as with the previously described solution, it is not always easy to accurately position the teeth in the desired seat with the ski boots on, so that the user can operate the biasing operation. It is not easy. Further, if there is snow or ice on the seat, it becomes very difficult to pull the pivot out of the seat or insert the pivot into the seat. Furthermore, since the skier often buckles and rotates the legs backward to grip the flap, it becomes more difficult to operate the flap while wearing ski boots. As a result, strong pressure is applied to the teeth, making it more difficult to pull out the teeth.

[0009] DE 28 07 371 discloses a device for adjusting the legs with respect to the shell of a ski boot. The device comprises an eccentric element rotatably associated with the leg. This eccentric element interacts with a conformable support projecting to the rear of the shell in a region below the lower edge of the leg. Even this solution has some of the disadvantages described above, as it is not easy for the user to bias the eccentric element with the knob. This is because the biasing of the eccentric element by the knob is performed in a state where the leg is placed on the shell. And since friction is generated with this, it is very difficult, if not impossible, to rotate the eccentric element and change its function.

In each case, this solution makes it possible to change the rearward rotation and the forward inclination of the legs by changing the position of the eccentric element relative to the support. The ski boot disclosed in U.S. Pat. No. 4,499,676 includes a device for locking the legs to the shell. The locking device comprises a lever transversely associated with the leg. One end of the lever is adapted to engage a mating abutment element that projects into the rear of the shell.

The biasing operation of the lever is performed, for example, to enable walking when the lever is interacting with the contact element and the lever is pressed against the contact element by the lever operating position of the skier. . For this reason, even this solution has some of the disadvantages mentioned above. The ski boot disclosed in U.S. Pat. No. 4,934,075 is provided with a device for controlling the angular position of the legs relative to the shell. The device is mainly constituted by a knob rotatably associated with the rear of the leg. The knob has an eccentric plate at one end of the stem facing the shell. The eccentric plate is selectively positionable by a lever provided with an eccentric element in a suitable seat formed in the shell.

[0012] The urging operation is difficult because the knob must be urged while the load is being applied to the plate by the legs. For this reason, even this solution has some of the disadvantages mentioned above. In addition, accurate biasing requires reduced knob tolerances with respect to the seat formed in the shell. Also, during sports exercises, considerable stress is applied to the seat, resulting in deformation or damage to the seat that hinders the adjustment operation.

The ski boot disclosed in EP 0 522 282 A1 is provided with a knob-shaped device rotatably associated with the rear of the leg. This device has a stem inside the leg. One end of the stem is shaped to form an inclined plane and interacts with a pawl pivoted transversely to the leg. The pawl swings against a spring formed in the shell and pressing the pawl against the abutment element.

Even this solution has some of the disadvantages described above, since the biasing of the knob is performed with the skier resting the legs of the boot on the rear of the shell.
With the legs resting on the rear of the shell, the ends of the claws are blocked by the abutment elements formed on the shell. Since the knob stem has an inclined plane shape, it is difficult to change this state.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the accompanying drawings, reference numeral 1 is used to adjust the position of a leg (quota) 2 with respect to a shell 3 of a sports shoe 4, such as a ski boot, a skate boot, a snow boot or a trekking boot. Is shown.
The first seat 5 is formed at the rear of the leg 2 in the longitudinal direction. A suitable storage housing 6 for the adjustment device 1 is preferably associated with the first seat 5.

Alternatively, the adjusting device 1 may be directly associated with the rear of the leg 2. The use of the housing 6 allows the housing 6 to be associated with the legs 2 after the adjustment device 1 has been pre-assembled in the housing 6, and is therefore suitable for industrial production. The adjusting device 1 comprises first means for preselecting the desired interaction between the leg 2 and the shell 3. The first means is constituted by a knob 7 pivoted transversely to the side 8 of the housing 6. Alternatively, the knob 7 may be pivoted directly to the side of the leg 2.

The knob 7 is connected to a plate 9 disposed inside the side surface 8 of the housing 6 or the side surface of the leg 2. Preferably, the knob 7 has a circular flat part and an eccentric element 10 projecting inside the leg 2. Knob 7
It rotates firmly with the plate 9. Also, the adjusting device 1
Has a second temporary engaging means associated with the shell 3. The abutment or positioning portion 11 formed directly on the rear of the shell near the edge 12 of the shell 3 by reducing its thickness constitutes a second temporary engagement means.
Alternatively, a second temporary engagement means is obtained by associating a shell with a conformable plate having a suitably shaped surface.

The adjusting device 1 is provided with first preselection means 7.
And third means for interacting the second engagement means 11 with the second engagement means 11. The third means can be biased by the movement applied to the leg 2. The third means is constituted by a swivel element (swivel element) 13 preferably formed in a parallelepiped shape. This turning element 13
Is pivoted at a first upper end 14 in a transverse direction of the leg 2 or the shell 3 by a conformable pivot 15.

The pivot element 13 is therefore accommodated in a conformable second seat 16 formed in the shell 3 or the leg 2. Flexible elements such as springs 17 are arranged coaxially with the pivot 15. Both ends of the spring 17 are associated with the pivot element 13 and the eccentric element 10. The swivel element 13 has a partially hollow interior and the eccentric element 10
And a plate 9 provided with a spring 17.

In the first operating position shown in FIG. 1, the turning element 13 is
A set load is applied to the spring 17 in advance so that the spring 3 is adjacent to the facing surface of the shell 3. The pivoting element 13 also has a third seat 18 formed adjacent to a back surface 20 thereof. In the second operating position, the knob 7
When the knob 7 is rotated to apply a load in the opposite direction to forcibly move the pivoting element 13 in a direction away from the shell 3, the pivoting element 13 receives the plate 9, the eccentric element 10, and the spring 17. It is supposed to.

The engagement between the one end of the spring 17 and the eccentric element 10 causes the first means 7 and the third means 13 to interact. The pivot element 13 has a second lower end 19. In the ski exercise condition shown in FIG. 1, the second lower end 19 is attached to the contact portion or the positioning portion 11 formed on the shell 3.
Is placed to cause the second means 11 and the third means 13 to interact.

The operation of the adjusting device 1 is as follows.
In the ski exercise condition shown in FIG.
Forces the pivoting element 13 adjacent the shell 3, so that the second lower end 19 of the pivoting element 13 interacts with the abutment or positioning part 11 provided on the shell 3. The same rotation applied to the knob 7 is applied to the plate 9 and the eccentric element 10. Eccentric element 1 shown in FIG.
The rotation of 0 by about 180 degrees places a set load on the spring 17 in the opposite direction to the previous one, and thus the spring 17 tends to act to move the pivoting element 13 away from the shell 3.

In this situation, the first pre-selection means 7 is energized to shift from the ski exercise condition shown in FIG. 1 to the walking condition shown in FIG. In this condition, the third interaction means 13 is re-energized and the second lower end 19 of the pivot element 13 is brought into contact with the abutment provided on the shell 3 by friction or a set load which prevents the pivot element 13 from disengaging. Alternatively, it interacts with the positioning unit 11.

If no frictional force is generated, or if the frictional force disappears immediately due to, for example, a slight forward swing of the leg 2, the pivoting element 13 is pressed outward by the spring 17 and separated from the shell 3. Is forcibly moved in the direction of
Under these conditions, as shown in FIG. 4, the second lower end 19 is detached from the contact portion or the positioning portion 11, and the leg portion 2 can be vertically arranged.

Thus, it is clear that the present invention achieves the intended purpose, and that a user can very quickly and easily preselect two distinct operating positions for the leg 2. It is clear that will be provided. In the tilt operating position, free forward swing is possible, and in the vertical operating position, free forward and backward swing is enabled. Since the user only has to overcome the force due to the set load of the spring 17, the urging operation of the adjusting device 1 is very easy.
Once the skier or user stands up after the knob 7 has been suitably rotated, the desired and preselected function is achieved.

Further, according to the adjusting device 1, since the user does not need to directly watch the operation to be performed on the knob 7, it is easy to bias the adjusting device 1. The device 1 is very simple and inexpensive. FIGS. 5 to 8 show the legs 102 with respect to the shell 103 of the sports shoe.

The first means for presetting the desired interaction with the device 3 is constituted by the knob 107. This knob 107
Is pivotally transversely pivoted to the side surface 108 of the housing 106 or directly to the side surface of the leg 102.

Also in this embodiment, the knob 107 is rotatably and firmly connected to a plate 109 disposed inside the housing 106. The eccentric element 110 projects from the plate 109 inside the housing 106.
Further, the adjusting device 101 includes second means for temporarily engaging the shell 103. The second means is
Near the rim 112, it is constituted by an abutment or positioning part 111 formed directly on the rear of the shell 103, or by a suitable, suitably shaped plate associated with the shell 103.

The adjusting device 101 includes third means for causing the first preselecting means 107 and the second engaging means 111 to interact with each other. The third means can be biased by a movement applied to the leg 102. The third means is the turning element 1
13 The turning element 113 is provided with the first upper end 11.
At 4, a rotatable pivot 115 is pivotally mounted to the leg 102 or the housing 106 in a transverse direction by a conformable pivot 115.

A flexible element such as a spring 117 is disposed coaxially with the pivot 115, and both ends thereof are pivotally connected to the pivot element 11.
3 associated. Unlike the solution described above, a tab 121 is interposed between the two ends of the spring 117 and is integral with the pivot element 113. When the tab 121 is interposed between both ends of the spring 117, the spring 117
Is set in advance.

Accordingly, when the eccentric element 110 is rotated by rotating the knob 107, an acting force is applied to one of the two ends of the spring 117, and the set load of the spring 117 increases, thereby obtaining the effects described in the previous embodiment. The same effect is achieved. Further, play between various components can be eliminated by first applying a set load to the spring 117 in advance.

This solution also achieves the object contemplated by the present invention and makes it possible to eliminate play between the various parts. FIG.
