Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a ski boot with closure and adjustment device.

PRIOR ART AND ITS PROBLEMS The closing or latching devices that are often attached to ski boots generally consist of several hooks, the configuration of which may vary, but in practice they act on the principle of leverage. is well known.

This type of closure device, although generally accepted, is often difficult to operate, especially under unfavorable environmental conditions for operating its hooks or latches, and the locking device to be applied is The attachment does not allow the force to be adjusted quickly, easily and precisely.

In order to solve such problems, the so-called Maltese
Maltese crossmechanism
Other devices have been proposed, such as chanism). However, it has been found experimentally that the mechanism is virtually impossible to fine-tune, and that the mechanism is susceptible to accidental release due to vibration or other accidental factors.

The device known from German Patent Publication No. 365,414 consists of a box-like body connected to one of the flaps of the ski boot to be tightened and provided with a knob for actuating a spool to which the other flap to be tightened is connected. The cable can be wrapped around the flap. A ratchet gear is provided which can be operated by said knob and which locks the spool in a desired position when the knob is turned in one direction and releases the spool when the knob is turned in the opposite direction. do. This device can be released with a push button mechanism. However, this configuration requires the user to perform various voluntary movements to operate the device.

European Patent Application Publication No. 0056953 discloses a method for fixing and releasing the spool by converting the rotational movement of the knob into an axial movement in one direction, and into an axial movement in the opposite direction when the rotational M movement is reversed. teaches a partial answer to the above problem by incorporating a transmission mechanism that performs.

However, such conventional devices also have some inconveniences. One of them is the inability to quickly close and optimally tighten the ski boots when operating the device, especially under the adverse environmental conditions often encountered while skiing.

Another disadvantage of the prior art devices is that their complex construction and multi-component components increase assembly time during manufacturing, which adversely affects the cost of the final product.

Another drawback of known types of closure and adjustment devices for ski boots is that they cannot be used effectively and quickly when the user is wearing gloves.

Another drawback found in using the known device is that it cannot be released quickly and easily to release the waistband of the ski boot.

Further disadvantages of the known closure and 31-section devices are that, because of their complex construction, they are often unreliable and that their manufacture necessarily requires the use of special plant or equipment. be.

The main goal of the invention is therefore a ski boot with a closure and 7JJTi device and an adjustment for the ski boot which solves all the problems found in the production and use of ski boots with a closure device of the known type. and equipment.

Among the above objectives, the object of the present invention is to propose a ski boot with a closure and adjustment device that makes it possible to quickly close the waistband and then tighten it quickly and optimally.

Within the scope of the above goals, another important objective is to create a closure that combines the above features with the features of simple construction and the ability to be used quickly and effectively, even when the user is wearing gloves. It is an object of the present invention to provide ski boots equipped with a dual-adjustment device.

Another object is to provide a ski boot with a closure and adjustment device that allows quick opening of the waistband.

A further object is to provide a closure and regulating device which has optimal characteristics with respect to reliability and safety in use and which can be manufactured using conventional plant and equipment and is advantageous from a purely economic point of view. It is to provide ski boots that have.

The above aims and objects, and other objects which will become apparent below, provide a ski boot with a closure and adjustment device consisting of a shell joined to at least two waist straps, the ski boot having a closure and adjustment device; a base connectable to one of said at least two drums rotatably supporting a drum, said drum having at least one pulley and at least one toothed spool; an end of a cable carrying another one of the waist straps is coupled to said pulley, said toothed spool cooperating with a first releasable engagement means;
This is achieved by a ski boot characterized in that a lever is connected to said drum, which interacts with said at least one spool by means of second releasable engagement means.

Advantageously, elastic biasing means are provided between the drum and the lever, which are adapted to be loaded when the waistband is released.

Other features and advantages of the invention will become apparent from the following detailed description of two exemplary embodiments, illustrated non-limitingly in the accompanying drawings.

(Examples and effects) The present invention will be described in more detail below in conjunction with the accompanying drawings.

Reference numeral 1 indicates a closure that can be used in particular to fasten the rear waistband 2 and the front waistband 3 of a ski boot 4;
! The i-adjustment device is shown.

The device 1 comprises a base 5 with a plane 6 which can be connected to the rear waistband 2, and from the side of said plane 6 a pair of substantially parallel shoulders 7a.

It is adjacent to the outside of 8b.

The lever 14 is pivotally mounted on the drum 9 and has two side tabs 1
5a and 15b, and a second cam 16 at each end thereof.
a and 16b are provided.

The second cams 16a, 16b each have an axial bore with a diameter that approximately corresponds to the diameter of the drum 9, are pivotally connected to this drum and are arranged between the toothed spool and the pulley.

An end of the spring 17 is connected to the drum 9 and is arranged coaxially with this drum, and the other end of the spring 17 is connected to the base 5.
is connected to surface 6 of the

The rectangular sea) 18 is the shoulder part 7a of the base 5.

7b, the seat is arranged relative to the longitudinal axis of said shoulder so as to extend substantially radially relative to the bore 40 formed axially in the cams 8a, 8b. It's leaning.

Said seat accommodates first releasable engagement means consisting of a first plate 19 which occupies the entire space between the shoulders 7a, 7b and slides freely within the seat 18. End portion 19a.

I have 19b.

At the periphery of the plate 19 there is provided a shaft 20, which is formed correspondingly to a surface defined by a flat bar 22 joining said shoulders 7a, 7b and the lower end of the surface 6. can freely slide inside the seat 21. Said end is advantageously directed towards the heel region of the boot 4.

A first cylindrical helical compression spring 23, coaxial with the shaft 20, acts between the flat a22 and said plate 19.

By rotating the /<-14 in the clockwise direction, as shown by the arrow 100 in FIG. 1, the user imparts rotational motion to the drum 9 and the toothed spools 13a, 13b. The teeth of this spool are configured to releasably snap onto the end of plate 19. plate 19
was guided to move within 1B,
It is biased by a spring 23 to cooperate with the spool. Thus, the plate 19 allows unidirectional rotation of the drum 9, but its ends are connected to the cams 16a, 16b of the lever 14.
protrudes outside the sheet 18 by a sufficient length to interact with the sheet 18.

The cams 16a, 16b, starting from a diametrical axis coinciding with the longitudinal axis of the tabs 15a, 15b, are larger than the diameter of the arrangement of the teeth ends of said spools, if the lever 14 is in the plane of the arrangement of the base 5. On the other hand, it has an outer diameter such that when rotated at an obtuse angle, the play 19 and the spools 13a, 13b are separated.

The lever 14 is connected to the toothed spool 13a.

A longitudinal seat 24 is formed on the side tabs 15a, 15b of the lever 14 for a second means of releasably engaging the lever 13b. Said second releasable engagement means is a second releasable engagement means whose end is guided and slid into said seat 24.
25, said second plate having a tongue 26 projecting from approximately the center of its periphery, said shaft being connected to the lever 14 on the side opposite the cams 16a, 16b. slides freely in a suitable seat 27 provided on a rod 28 which laterally connects the tabs 15a, 15b of.

A second cylindrical helical compression spring 29 is provided coaxially with the tongue 26 and interposed between the rod 28 and the second plate 25.

The spring causes the second plate 25 to cooperate with the spools 13a, 13b. This second plate therefore provides means for imparting a rotational movement to said spool and to the drum 9 to which it is rigidly connected when a clockwise rotation in the direction shown in FIG. 1 is applied to the lever 14. be.

The detachment of the plate 25 from the toothed spools 13a, 13b occurs due to the presence of cams 8a, 8b. The cams 8a, 8b have an outer diameter that is larger than the diameter of the end arrangement of the teeth of said spool at the location of the diametrical axis which substantially coincides with the longitudinal axis of the sheath 18.

The second plate 25 is provided with a pair of fins 30 at the connection point of the tongue z6, which protrude substantially perpendicularly to the plane on which the second plate 25 is located, in a direction that allows the user to easily operate the second plate 25.

The operation of the closure and adjustment device described above is as follows. Assume that the waistband is tightened and the lever 14 is in the position shown in Figure 1.3.4.

In this state, the cable 12 naturally connects to the pulleys LOa and l.
Assume that it is wound around the ob.

To release the waistband, the skier manually moves the plate 25 onto the toothed spool 13a,! 3b, this operation can be done by applying force to the fins 30.

In this way, the skier can use cams 8a, 8b with a larger outer diameter than that of the tooth arrangement of said toothed spool.
The lever 14 can be rotated until it is located in the area.

In this state shown in FIG. 6, the cam 16a.

16b connects the rod 19 to a toothed spool 13a.

13b at the same time, allowing the drum 19 to rotate freely.

The skier then attaches the cable to the pulley lOa by applying a slight force to the waistband to allow it to release.

They must be unwound from 10b at the same time.

As a result, the drum 9 rotates and applies a load to the spring 17. If the waist straps separate, the skier must move the plate 1 in order to maintain a stable release state.
9. Lever 1 until 25 engages said toothed spool.
4 must be rotated slightly.

To close the waistband, the lever 14 is pressed against the plate 19,
It is necessary to rotate the same lever again until 25 is removed from the toothed spool. Since the drum is still free, when the skier manually pulls the waistband together, the spring 17 releases and provides a rotation that allows the cable 12 to unwind. To finally adjust the tension of the cable, the toothed spools can be rotated by alternately rotating the blades 14 so that the teeth 19 engage the teeth one after another. In this case, the cams 8a, 8b act as pivots for the swinging of the lever and prevent it from accidentally assuming the disengaged position. When the optimum fixed positional relationship is achieved, Shihachi-14 comes into contact with the waistband 2,
Its free end faces the heel region of the boot 4.

7 to 9 show another embodiment of the invention of the present application, in which it is possible to simultaneously close the waistband and fix the foot. The device indicated generically in FIG. 8 by the reference numeral 100 is device 1 (FIGS. 1-6), except for changes in the minus part.
It is made of substantially the same materials as. In particular, two pairs of boos 9 are connected to the ends of the drum 9, a first pair of pulleys 10a, 10b and a second pair of pulleys 10c, 10d. Similar to the previously described device l, the pulley lOa.

10b engages the end of the first cable 12 carrying the second waistband. The pulleys lOc, lOd are provided with radial grooves 11a that engage with the ends of the second cable 12a and the third cable 12b, respectively. Cables 12a, 12
b unravels along a symmetrical path inside the shell of the boot and transversely carries a suppressor 101 acting on the instep.

Advantageously, the free ends of the cables 12a, 12b are connected to means for adjusting the effective length of the cables, which are fastened to externally operable parts of the waistband.

The adjustment means 102 is, for example, of the type shown in FIG. It is provided with a shaft portion 105 that protrudes to the outside of the leather. A lever 106 is coupled to the free end of the shaft 105 to facilitate rotation of the shaft 105 by a user.

The first block 106a and the second block 106b are each a threaded portion 104a.

104b, and when the shaft portion 103 is rotated, the blocks 106a and 106b are translated in opposite directions. The cables 12a and 12b each have a ring 107a,
It is connected to blocks 106a and 106b by 107b. By rotating the shaft portion 103 using the lever 106, the effective lengths of the cables 12a, 12b are adjusted.

The cables 12a and 12b have their ends connected to pulleys 10c and 1
0b and an effective length adjustment means of known type provided in an intermediate position, which can also be provided - weight or comprehensively.

Naturally, the path of the cables 12a, 12b can be changed as required and in consideration of the configuration of the foot press. - For example, the type of suppressor ζ that acts on the heel.

The device 100 is different from the device 100 except that in the device 100, the closing of the waistband and the fixation of the foot by the pressing body 101 are performed at the same time.
The operation of is exactly the same as that described with respect to device I (shown in FIGS. 1-6).

Conveniently, the adjustment means 102 are adapted to allow adjustment of the effective length of the cables 12a, 12b and adjustment of the pressure acting on the feet separately. Note that the result of this adjustment is stored or modified by the adjustment means 102, so
There is no need to adjust the boots each time the boots are put on; in fact, after putting on the ski boots, the skier operates the υ bar 14 to close the waistband, and then uses the adjustment means 102 to close the waistband.
The pressure applied to the foot by the pressing body 101 is adjusted. To remove the boots, operate the lever 14 as described above to release the waist leather, and at the same time free the foot from the action of the pressing body 101.When putting on the boots again, the adjustments made earlier should be made. Adjustment means 1, except when changing the result of
Since there is no need to operate 02 again, it is only necessary to operate lever 14.

As can be seen from the foregoing, the present invention achieves the above aims and objects and provides a device that allows the closure and adjustment of the waistband of a ski boot and, ultimately, the simultaneous fixation of the foot. .

This operation can be performed even when the skier is wearing gloves, and allows the optimum desired pulling action to be applied to the cable quickly and easily.

Naturally, the number of teeth provided on each toothed spool may be determined appropriately depending on the degree of adjustment desired.

Naturally, the materials and dimensions of the individual parts may be determined as necessary.
