DESCRIPTION:
BRIEF SUMMARY
The invention relates to a cross-country or touring ski binding including a hinged liner including a holding element which reaches over complementary engaging elements of the sole.
A binding of this type is known from the DE-U-93 20 530. This binding distinguishes itself by robustness, good guidance properties as well as operationally safe operation; however, it is relatively elaborate in it design and thus of relatively heavy structure. However, these features play only a subordinate part for an adult binding. The emphasis of the conventional binding consequently lies in creating a particularly robust and operationally safe binding for extreme applications.
It is, therefore, an object of the present invention to offer a binding which is clearly simpler with regard to structural needs and which manages with a minimum of components and which is of respective lightweight design, so that it is suitable particularly for children.
SUMMARY OF THE INVENTION
This object is achieved according to the invention by the binding including the hinged holding element constructed with the locked position of the holding element defined by detent elements configured on the operating lever and the binding, in such a manner that detention is carried out on its own, i.e. independently from the load of a flexor or other spring-elastic locking elements, by positive co-operation of the detent elements structural details and further developments of the basic scope of the present invention are described in the subclaims. This applies in particular to a particular design, which is independently from the binding design, and wherein the holding element in the shut or closed position reaches over the hinge axis and includes a recess or cutout extends parallel to the hinge axis. As a result, during an upward parallel pivotal movement of the shoe heel against the load of the flexor no force component, or only an insignificant one, is applied in the opening direction of the holding element.
Thus, the basis of the present invention lies in that the locking and release position of the holding element are defined by respective detent positions of the handle or the operating lever to which the holding element is coupled. This way, locking springs and beyond dead-centre structures can be dispensed with. This allows a considerable reduction in structural needs. When making the operating lever of plastic, then a particularly lightweight structure is possible which offers itself in particular for children. The detent positions provided according to the invention clearly show a child that the binding is either in the release or locking position. When operating the operating lever, the child can feel which position the holding element is in. The entire binding includes only a few parts, i.e. a flexor, the operating lever including pivotal axis, the holding element and the binding housing or the base on which the aforementioned elements are mounted. This base is preferably composed of a sheet metal element, wherein the base includes two laterally upward bent jaws and in its mounted state at the rear an upward bent edge web which serves as a front stop for the hinge axis configured at the front sole of the shoe. A structural which is suitably shaped for fixing the operating lever, flexor and holding element, in particular in accordance with Claim 4. Fixing the flexor on the aforementioned base element is also carried out by the aforementioned parts, i.e. the operating lever or its pivotal axis on the one hand and the holding element on the other hand. Separate fixing means are then not required which particularly simplifies the overall design. The holding element in one embodiment is formed by a U-shaped bent wire lever. This form of embodiment also contributes to a reduction in overall weight.
Furthermore, the wire lever prevents, in contrast to plateshaped locking elements, inclusion of snow or ice within the binding which ensures lasting operational efficiency. This form of embodiment is also claimed as an independent structural variant.
