ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a plate-like support element for coupling elements, in particular for a ski binding, which is arranged between the coupling elements and the surface of the ski and is designed to comprise several parts along the longitudinal extension of the ski.
2. The Prior Art
A support element is known from DE 41 24 965 A1, which is arranged between the coupling elements and the surface of a ski and is formed by two mounting sections spaced apart from one another along the longitudinal extension of the ski for damping elements forming the coupling elements. The damping elements comprise spacing elements provided with bores running perpendicular to a surface of the ski, which are penetrated by securing elements, by which the coupling elements are connected movably to the ski. A disadvantage of this design is the introduction into the ski of clamping forces acting between a ski shoe and the coupling elements as a result of which its bending characteristics are changed and its damping behaviour is also worsened by the support of the coupling elements on the ski surface by the spacing elements.
A further plate arranged on a surface of a ski for mounting a ski binding is known from AT 396 749 B, which comprises a continuous plate-like damping elements common to both coupling elements, by means of which and by means of spacers are arranged for mounting the ski binding elements that are spaced apart from the surface of the ski and spaced apart from one another along the longitudinal extension of the ski. The plates have depressions for mounting the heads of securing elements which penetrate the plates and the damping element, whereby between the plate and the heads of the fastening screws connecting the plates to the ski, damping rings are arranged, in order to permit relative movements caused by the bending and vibration of the ski. A disadvantage is the reduced lateral sensitivity, which makes precise ski guiding more difficult with high lateral forces.
SUMMARY OF THE INVENTION
The objective of the present invention is to create a plate-like support element which does not restrict the deformation movements of the ski and prevents the transfer of the thus produced vibrations and oscillations to the coupling elements. This objective is achieved in that the support element is formed by a support profile supporting the heel piece and the toe piece spaced apart from the surface of the ski by means of plate-like damping inserts, which are secured spaced apart on the surface of the ski along the longitudinal extension of the ski by a spacing element connected between the support profiles and to the latter by means of elastically designed hinge arrangements. The surprising advantage of this design is that the division of the support element into the support profiles for the coupling elements and the articulated connection of the latter with a spacing element spacing apart the latter, the damping effect of the support elements is retained regardless of the deflection caused by bending and vibration of the ski to an extent that can be predetermined by the material properties of the damping insert and to an almost constant order of magnitude and in this way a reliable and fatigue-free skiing on skis equipped in this way is achieved because of the absence of fluctuating influences on the user.
Further designs are advantageous, where means of which a vibration uncoupling between the ski and coupling element is achieved by fastening the support profiles by means of the fastening arrangement adjacent to the assembly point designed as a fixed bearing and the fastening arrangement for the support element spaced apart therefrom designed as a movable bearing and the vibration uncoupling is provided in that the coupling elements are fastened on the support profiles spaced apart from the ski surface by the interconnection of damping inserts, and thus the force flow occurs between the coupling elements and the ski via the vibration damping insert. In order to achieve the necessary retaining forces for the fastening elements of the coupling elements an insert made from high-strength material is provided, which is arranged as an otherwise loose flat stamped or cut out blank element between the support profile. In this case it is advantageous to characterise the region over which the insert extends, e.g. by means of a contour projecting on the surface of the support profile to facilitate the assembly procedure and the secure attachment of the fastening elements. The design of the support profile as a plastic injection moulding permits economical manufacture whilst maintaining constant quality of the parts. By means of the suitable selection of material for the damping insert and its dimensions, in particular the thickness, the support element can be adjusted to different conditions that are dependent on skiing ability and the intended use.
The design of the spacing element with an U-shaped cross section and side webs, which support the spacing element on the surface of the ski, is advantageous, as in this way a damping effect is also achieved in the region of the spacing element to reduce oscillations and vibrations, and in addition the penetration of snow, ice, dirt etc. and thereby a reduction in the function of the support element is effectively avoided. By means of providing slots in the side webs flexibility against bending and torsion is effectively maintained.
