Device for adjusting the position of the bootleg with respect to the shell, particularly for ski boots

Abstract

A device for adjusting the position of the bootleg with respect to the shell, particularly for ski boots.The first end of a blade is associated internally and at the rear with respect to the bootleg, the blade interacting selectively, at the second end, with a tooth of a slider.The latter is arranged adjacent to the heel and movable axially with respect to the shell in contrast to an elastically deformable element.

Description

[0001]The present application relates to a device for adjusting the position of the bootleg with respect to the shell, particularly for ski boots.BACKGROUND OF THE INVENTION[0002]In conventional ski boots, the problem is widely felt of being able to obtain only a limited rearward oscillation of the bootleg during sport practice and at the same time a free oscillation of the same bootleg once the sport is finished in order to achieve an optimal gait for the user.[0003]Thus U.S. Pat. No. 4,519,150 is known in which a ski boot is disclosed that is comprised of a shell to which a bootleg is pivoted, to the rear of the bootleg a lever being associated the actuation of which enables the activation of a bar that has a threaded end which interacts with a counter-threaded bush which can be arranged on an adapted abutment coupled to the shell.[0004]Such solution makes it possible to vary the flexibility of the bootleg with respect to the shell, thus allowing for example the optimal positionin...

AI Technical Summary

Benefits of technology

[0016]The aim of the present invention is to eliminate the above-mentioned drawbacks, and thus solve the technical problems set out, by devising a device that enables the user to obtain the free oscillation of the bootleg in order to walk or a limitation of such oscillation in order to be able to ski, the assembly being provided with a structural shape that is simple and of contained size.

[0017]Within this aim, an object of the invention is to enable the skier to achieve such two different conditions for the oscillation of the bootleg with respect to the shell automatically and thus without having to operate directly on adapted devices applied at the boot itself and irrespectively of the possible presence of snow or ice on the boot.

[0018]Another object is to provide a device that in addition to the above-mentioned characteristics also is relatively low-cost and enables an abatement of the overall costs, including a reduction in the provision of molds and for the mounting of the device on the boot.

[0019]Another object is to provide a device the activation of which, for skiing, and the deactivation of which, for walking, can be obtained without any direct intervention of the skier on the boot.

Problems solved by technology

Such a solution however has drawbacks in that manual intervention is required from the user for its activation, but it is not possible to achieve an optimal walking motion since the bootleg is not able to oscillate freely with respect to the shell even with the device deactivated.

Such projections however constitute a further drawback, given that they impair the aesthetic form of the boot as well as making it heavier.

Moreover, activation of the conventional devices is not always easy, given that the skier is usually wearing gloves and thus finds it difficult to grip levers and other devices especially in conditions of low temperatures.

Such conventional devices are very often not activated because the skier forgets them or, not perceiving the correct operation thereof, utilizes them in an incorrect manner.

Although such a solution is undoubtedly valid, it has a drawback owing to the fact that the bootleg and the shell have, in the region in which the device is located, a protrusion that increases the size of the boot, impairing the overall shape thereof.

Moreover there is a construction-related complication, although limited, both regarding the provision of the female mold part and regarding the assembly of individual parts that require a certain care in assembly.

Finally in such a solution it is possible for snow to be deposited and ice to form between the first arm and the first seat in which the first spring is accommodated, which can render the activation of the device more difficult.

Also known is EP0664969 which, although allowing an activation when the boot is anchored to the ski binding, still has a considerable encumbrance at the rear of the bootleg, which moreover extends in a lower region almost to the sole, as well as a high structural complexity and an operation that requires high precision for achieving for example the optimal interaction between the tab and the seats, where it is possible for them to stick and thus thwart the operation.
