Binding device for securing a boot suited to walking to a gliding board

Abstract

Front binding device for securing a boot to a gliding board comprising a jaw connected to a device comprising a release mechanism, wherein the jaw comprises a securing bar having a bearing surface sloping upward and a base kept in contact with the device by a connection allowing the jaw to rotate laterally and vertically with respect to the device. Sports boot able to be fixed to a gliding board comprising a sole, comprising a rear kerb to be fixed by the jaw of a heel piece, wherein the sole comprises a hollowed-out region, a binding element having the shape of a V pointing toward the front of the boot, the hollow of the V-shape being approximately centered on the width of the boot, positioned toward the front of the boot and placed above the hollowed-out region.

Description

BACKGROUND OF THE INVENTION [0001] The invention relates to a releasable binding device for a gliding board, which we shall also term more simply a “binding”, for securing a boot to a gliding board while at the same time allowing it to be released when it experiences loadings above a certain threshold, for safety reasons. More specifically, the invention relates to an end stop for such a binding, to a boot compatible with this end stop, and to a boot / binding system. It also relates to a set of boot / binding systems in which the boots represent the set of existing shoe sizes. It is particularly suited to ski bindings. DESCRIPTION OF THE PRIOR ART [0002] A conventional ski binding is made up of a heel piece and of a front end stop, which are positioned on a ski, comprising jaws that collaborate with rear and front kerbs provided on the soles of the ski boots. These jaws are connected to complex mechanisms for implementing the release functions to release the boot. Ski boots have of nec...

AI Technical Summary

Benefits of technology

[0010] A second object of the present invention is to propose a binding device for securing a boot to a gliding board that is not too bulky.

[0012] A fourth object of the present invention is to propose a binding device for securing a boot to a gliding board that is simpler.

[0023] The sole may also comprise a front region that is curved to make walking easier.

Problems solved by technology

A first disadvantage with these boots stems from the fact that they are ill-suited to walking, because of these soles, and this makes moving around when not wearing the skis somewhat difficult.

A second disadvantage of these bindings stems from the fact that they are dependent on the shoe size of the boot because their separation has to correspond to the length of the boot, so as to collaborate with its front and rear kerbs, which makes them complicated devices.

A third disadvantage with these bindings stems from the fact that they lead to a significant bulk on a gliding board because one device is positioned at the front and one at the rear of the boot, something which is not very attractive and is an impediment in the case of gliding boards the length of which may be short.

the entire binding operation is performed using elements positioned under the sole and the skier has no visual frame of reference for correctly positioning his foot, making the solution somewhat un-user-friendly and potentially leading to incorrectly secured bindings;

The benefit of many years of development of these highly sensitive release mechanisms is lost and there is a risk that this solution will present problems of reliability and of safety;

such a binding does not answer the problem presented by the commonplace presence of snow stuck to the underside of the boot, known as a wedge of snow.
