Abstract

The ski binding has front and back holding systems for holding a ski boot. Each holding system acts together with a releasing system. The releasing systems (101, 102) have release springs (113, 114), decoupled from the associated holding system and arranged in or at the ski or a unit connectable with the ski. The releasing systems are coupled with the holding systems during positioning of the holding systems.

Description

The invention relates to a ski binding which can be arranged on a ski and has a front and a rear holding system for holding a ski boot inserted into the binding, wherein each holding system interacts with a release system which has at least one release spring and if necessary causes release of the ski boot.

In the case of the usual ski bindings, the holding systems for the ski boot and the triggering systems interacting with these, which usually have a release spring and a blocking element or the like cooperating with the retaining systems, are a structural unit. In particular, the accommodation of the release springs claimed relatively much space, so that these ski binding parts have a certain size and longitudinal extent of the ski. The ski-mounted ski binding parts stiffen the ski over a certain length, which can hardly be undershot due to the design. In order to influence the properties of the ski or the respective Skikistruktion as little as possible, it would be advantageous to build the ski binding compact.

The invention is therefore based on the object to perform a ski binding of the type mentioned above, that it is constructed much more compact than conventional ski bindings, in particular, the required extent of the binding parts in the longitudinal direction of the ski should be significantly lower than in conventional bindings.

The object is achieved according to the invention in that at least one of the trigger systems of the associated holding system decoupled in or on skis or a connectable with the ski element is arranged, and that the coupling takes place in the positioning of the holding system on the triggering system.

In a ski binding system according to the invention, therefore, at least one of the trigger systems does not form a structural unit with the holding system. Only with the positioning of the holding system on the ski, the coupling is made with the trigger system. This makes it possible to make the holding systems and the trigger systems compact and easier and to accommodate the trigger systems to save space.

It is particularly advantageous if the triggering system is located below the holding system with the holding system positioned on the ski. This measure makes it possible to carry out the components of the ski binding positioned on or in the ski with a short extent in the ski longitudinal direction.

For easy handling of the arrangement of the holding systems on the ski, the release systems are provided with elements for positioning and releasably securing the holding systems.

In a particularly space- and weight-saving design of the ski binding according to the invention, the release system in the ski, at least largely below the ski upper side, housed.

In an alternative embodiment, the trigger system is slidably mounted on a rail-like guides, attached to the ski element in the ski longitudinal direction.

A compact and lightweight design of the ski binding, which can also be comfortably positioned on the ski, has a front and a rear holding system and a front and a rear release system, wherein the two trigger systems are releasably connected to a connecting band, which at the ski, also detachable, can be fastened.

For ease of assembly, it is advantageous if the connecting band is mounted centrally between the two trigger systems on the ski.

For variable adjustment of the mutual distance of the two holding systems is provided to connect the connecting band with the two trigger systems in different longitudinal positions.

The respective trigger system should be simple, functional and functional. A particularly advantageous variant of the embodiment of the triggering system therefore provides that this has at least one, adjustable in its bias release spring, which acts on at least one coupling element, which is operatively connected to at least one coupling element of the holding system, in particular by direct contact.

Is that or are the trigger system (s) housed in the ski, a direct coupling of the holding system with the trigger system without the use of a connecting band for a compact design of the ski binding advantage. Also in this case, it should be ensured that the mutual distance of the two holding systems can be adapted to different ski boot sizes. For this purpose, it is provided, for example, to provide each triggering system with at least three coupling elements spaced apart in the longitudinal direction of the ski.

The operative connection of the coupling elements of the holding systems with the respective sole holders, angle levers or the like should be functionally reliable and still simple. The coupling elements of the holding systems are therefore indirectly or directly connected to the one or the ski boot holding components. The coupling element of the rear retaining system may for example be part of a pivotable blocking element, which acts on the sole holder.

If a front holding system is used which has two angle levers, then each angle lever can be provided with a coupling element.

The fixation of the respective holding system on the trigger system can be done in a simple manner by means of locking elements, which are arranged on the holding system and can be used in the housing of the triggering system and at least partially fixed.

In a ski binding system, with accommodated in the ski release systems is advantageously provided to be able to fix the respective holding system in several longitudinal positions on his trigger system can. The number and the mutual distance of the positions corresponds to the number and the distance of the coupling elements of the triggering system.

The housing, which receives the triggering system and which is used in the ski, is preferably carried out in the manner of a flat, elongated and largely closed box. In a particularly preferred embodiment of the invention, this box is already connected in the production of the ski with this.
