Boot for a binding

Abstract

The invention relates to a boot for a binding, which is suited for alpine skiing, ski touring, cross-country skiing, telemark skiing and also for other snow sliding sports, the boot having greater comfort in wearing and moving. Moreover multifunctional components make it possible for the overall equipment with which the snow sportsman is burdened to have low weight. The boot comprises an outer shell for holding the foot and a coupling part for fastening the boot in the binding, the boot being held in the boot tip region and in the heel region of the binding on the coupling part. The outer shell is movably connected to the coupling part, the connection of the outer shell to the coupling part being made such that in the state of the boot fastened in the binding the foot held in the outer shell together with the outer shell can be lifted in the heel region and lowered again in a walking motion. Furthermore the outer shell can be locked relative to the coupling part and there can be a climbing aid and a damping device for damping of the walking motion on the boot.

Description

TECHNICAL DOMAIN [0001] The invention relates to a boot for a binding, especially a ski boot, with an outer shell for accommodating and holding the foot and with a coupling part attached to the outer shell for fastening the boot in a binding so that the boot in the boot tip area and in the boot heel area can be held by the binding on the coupling part and the coupling part has a connection to the outer shell such that the outer shell can be lifted off the coupling part in the heel area in executing a walking motion and can be lowered again onto it, while the coupling part is fastened in the binding, and the outer shell can be pivoted around a geometrical axis transversely to the lengthwise direction of the boot. PRIOR ART [0002] Ski boots when skiing down are supposed to have high stiffness not only against lateral bending, but also against forward bending of the top part of the upper of the ski boot, and on the other hand during a natural walking motion without the skis or during a...

Benefits of technology

[0012] The object of the invention is to devise a boot for a binding which belongs to the initially named technical domain, which comprises a versatile and light alternative to existing boots for bindings, and which has high walking comfort.

Problems solved by technology

In previous years, with ski boots produced mainly of leather, due to the relatively low stiffness of the boot leather only limited support of the foot / lower leg could be achieved.

Since the advent of plastic ski boots however touring skiers are no long prepared to abandon the much greater hold and thus improved ski guidance in skiing down.

These touring ski boots however have the disadvantage that they make natural movements as occur in a natural walking motion or climbing when ski touring difficult or even impossible by the essentially stiff execution of the various boot components.

These improvements each for themselves do enable the ski boot to be made more comfortable in different ways, but do not solve the basic problems of natural movements which are to be executed in a stiff boot.

In particular in ski touring the problem of coordinated movement when climbing arises.

This causes a major cost burden for a skier who on the one hand pursues ski touring and on the other also skis on slopes.

In executing a natural walking motion without skis on a base the plate which is connected to the ski boot however prevents ergonomic movement, by which the aforementioned basic problems in natural movements remain.

Moreover the pivoting capacity which is achieved by the peripheral arrangement of the pivoting axis on the tip of the ski boot is recognized not to be very comfortable for the skier since the pivot is unfavorably arranged in ergonomic terms.

The versatility however arises only by using the entire set, i.e. in order to enjoy all the advantages of the set, the skier would have to carry different soles and different inner boots; this is undesirable in ski touring due to the additional weight.

In addition to a complicated and thus mechanically susceptible construction of the ski boot, both versions have the disadvantage that the joint of ball of the foot must be completely pivoted.

On the one hand, this yields a pivoting region limited by the joint of the ball of the foot, and high loading of that joint when climbing; in longer ski touring this can lead to considerable pain and moreover to injuries such as blisters.

Furthermore, in addition to poor comfort of the known boots and bindings in ski touring, the problem of the relatively great weight of the touring ski equipment which the skier must carry along also arises.

Likewise there are redundant elements, the redundancy arising generally from the combination of different system components such as ski boots and the ski binding.

Compared to the lightest touring ski bindings however even such a touring ski binding is heavy and causes an unnecessary weight burden on the skier.
