ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a mounting plate for a runner, having a mounting surface for a coupling mechanism, in particular a ski binding, for removably retaining a boot and having fixing mechanisms spaced at a distance apart from one another in the longitudinal direction of the mounting plate, and a runner, in particular a ski.
2. The Prior Art
A bearing element is known from DE 41 24 965 A1, which is arranged between the coupling components and the top face of a ski. It forms two receiving regions for the coupling components, spaced apart from one another in the longitudinal direction of the ski, and fulfils a damping function. Spacer elements are provided in bores running perpendicular to the top face of the ski, through which fixing elements extend and to which the coupling components on the ski are attached. The disadvantage of this design is that the clamping forces acting on the coupling elements are transmitted to the ski via the fixing elements, altering the bending characteristics thereof and adversely effecting damping behaviour due to the fact that the coupling components are supported on the top face of the ski by means of the spacer elements.
Also known from AT 396 749 B is a plate arranged on a top face of a ski for receiving a ski binding, which has another continuous plate-shaped damping element on which two plates are mounted, spaced at a distance apart, to receive the ski binding components. The bores for flxing, elements are surrounded by bevels for receiving the heads of the fixing elements, supported on the plates by means of ring-shaped damping elements in order to permit relative displacements. This design takes up relatively large surface regions which means that the fixing arrangement for the coupling components with the bearing plate has to be accurately matched, restricting the freedom of choice as to which coupling components may be used.
SUMMARY OF THE INVENTION
The underlying objective of the present invention is to provide a mounting plate, whereby the mounting surface is not adversely affected by recesses and fixing elements when attached to a runner, to which the coupling components or ski bindings can be directly attached and without fixing elements engaging in the runner, the final mounting of the coupling devices being simplified.
This objective is achieved in that the mounting surface extends across an entire mounting region for the coupling mechanism and inset recesses are provided in the region of the fixing mechanisms in the mounting surface, extending from longitudinal side faces of the mounting, plate in the direction of a longitudinal central axis. The surprising advantage of this arrangement is that it produces a standard-compliant mounting surface in terms of size and shape for attaching ski binding components or binding units, irrespective of the design of the top face of a runner. This allows a large amount of leeway in terms of the structural design of runners so that they can be adapted to a wide variety of and more specialised conditions of use and, this being the case, affording a free choice from the large rang e of coupling components ivailable. Mounting work is significantly simplified as a result because it is also possible to fit the runners with mounting plates of this type at the production stage, i.e. prior to delivery, so that the desired, selected ski binding can be mounted in a standard fitting process before handing over to the user. This rules out the possibility of errors inherent in faulty fixings and constituting a high safety risk.
It is also advantageous that the fixing systems used to attach the mounting plate to the runner are designed to provide longitudinal compensation for bending as a result of an arrangement incorporating fixed bearings and loose bearings, so that the clamping forces acting on the runner when the mounting plate is fitted do not affect its properties, as a result of which the inherent, structural properties predetermined for particular types or use, such as vibration behaviour and damping behaviour, etc., also remain unaffected.
The angled design of insert elements, which in certain cases serve as a means of anchoring fixing screws of the bindings, also have the effect of centring the insert elements relative to the centre point when bending forces are directed to the opposing ends of the runner due to flexing. This also increases friction surfaces between the inserts and the mounting plate, thereby preventing any unintended slipping, and any displacements of this nature are checked by the angled arrangement providing a secure seat for the insert elements in the mounting plate and hence the coupling components relative to the runner in all applications and situations.
Also of advantage is the matching design of the surface contour, e.g. the top face of the runner and the underside of the mounting plate, since this produces a positive mounting enabling high lateral forces to be transmitted without giving rise to increased shearing stress on the fixing elements.
It is also of advantage to use an intermediate section, enabling the standing height above a gliding surface of the runner to be varied without having to make mounting plates of varying thicknesses and mount them on bearings.
Another advantage is that the intermediate sections can be made from different materials in order to obtain different specific properties, e.g. damping action, to suit particular applications during use.
Also of advantage and falling within the scope of the invention is a runner, in particular a ski, where a mounting plate is attached to a top face of the runner in a mounting region for a coupling mechanism, e.g. for a ski binding, and the mounting plate is attached to the top face of the runner by means of an intermediate section, because they permit rapid, on the spot fitting and can be adapted to meet requirements within a large range of variability in terms of the combination of runner device and coupling device, avoiding faults during fitting.
