BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention refers to a ski binding support, comprising a support plate on which a ski binding is attachable, and means which are mounted on the ski in order to removably secure said support plate.
RELATED ART
A ski binding support of the general type is known from CH-A-637,299, where the support plate is held by three mouth-shaped grooves and is provided with a spring which mainly serves as a formfitting and force-transmitting attachment to the ski.
Due to the increasing popularity of skiing, on one hand, the growing prosperity and especially the technical improvements and refinements, on the other hand, there is a growing number of people who own more than one pair of skis in order to be able, according to the particular conditions, to use the appropriate ski. Moreover, ski resorts have a considerable number of shops where skis can be rented, providing an opportunity for customers to try different skis. These circumstances lead to an increasing need to reduce costs, of which ski bindings represent a major factor. Purely theoretically, the abovementioned ski binding support might provide an answer. Recent developments have shown, however, that a formfitting attachment of the ski binding to the ski is undesirable in many cases as it impairs the resilience of the ski. Thus, there are now ski bindings where the heel portion of the binding is connected by means of a flexible ribbon in order to avoid any stiffening of the ski. In such a case, however, the binding is directly mounted to the ski. This system is described in AT-B-371,730.
SUMMARY OF THE INVENTION
With the foregoing as a background, it is a first object of the present invention to provide a ski binding support which is not only easily exchangeable in order to be mounted on various skis but also allows the flexibility of the skis to be fully conserved. This object is attained by a ski binding support as illustrated in the accompanying drawings and the following description of same. A preferred embodiment provides a solution to the task of absorbing shocks which are imparted to the ski boots and thus to the skier. This problem is solved in that said support plate comprises a rubber-elastic shock absorber. The use of shock absorbers is know, as shown in EP-B-104,185, where a shock absorber is fixedly cemented above its entire surface between the ski and a non-exchangeable ski binding.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention is explained in more detail hereinafter with reference to the accompanying drawings in which:
FIG. 1 shows a schematical side view of a ski binding support according to the invention with a ski binding mounted thereon;
FIG. 2 shows the ski binding support of the invention from above;
FIG. 3 shows a longitudinal cross-section of the ski binding support according to FIG. 2;
FIG. 4 shows a transverse cross-section through line IV--IV in FIG. 2;
FIG. 5 shows a transverse cross-section through line V--V in FIG. 2; and
FIG. 6 shows a longitudinal cross-section for an alternative embodiment of the ski binding support of the invention for a touring binding.
FIG. 1 shows ski 1, ski binding support 2 of the invention, as well as toe portion 3 and stopper 4, 5 of binding 6, which is mounted to the support plate 7 in exactly the same manner as when attached directly to a ski.
DETAILED DESCRIPTION OF THE DRAWINGS
The first embodiment of the ski binding support of the invention illustrated in FIGS. 1 to 5, is composed essentially of three parts: support plate 7, securing piece 8 at the front, and the guiding piece 9 at the back. As opposed to the previously mentioned binding having a heel portion which is flexibly connected to the ski, reference is here made to a support plate 7, and it is therefore possible as well to provide the securing piece at the back, near the heel, and the guiding piece at the front, since it is only essential that a relative displacement of the support plate 7 with respect to the ski 1 is possible.
Securing piece 8, see also FIG. 4, comprises a U-shaped securin
