DESCRIPTION:

BRIEF SUMMARY
The invention concerns a ski safety binding.
Such a ski binding is essentially described in the Austrian Pat. No. 330,632. In the known solution, the locking member is designed in such a manner that the heel holder will be actuated in the presence of both excessive lateral forces and of those in the vertical plane. As a result, the toe piece can be made as a simple holding bail and therefore the ski shoe fastener can also become very simple in front of the sole plate. On the other hand, the known design suffers from the drawback that the sole plate is secured against lifting in the heel zone only by the cooperation between the spring-loaded compression part and the associated fastener fixed in the ski. Consequently, changes in the position of the sole plate, taking place during ski flexure over ground irregularities, will affect the release mechanism of the ski binding.
A further ski binding of this species is known from the German Offenlegungsschrift 33 42 155. In this known ski binding, these fasteners, fixed in the ski, partly overlap the sole plate both at its front and rear, thereby securing it against lifting off from the ski. As a result however, the sole plate may jam or stress in the fasteners during ski flexure. Also, the sole plate is made rigid for reasons of strength and thereby hampers ski flexure, which in turn adversely affects skiing properties.
The object of the present invention is to avoid the stated drawbacks and to prevent clamping the ski boot or the sole plate when the ski is moving over uneven terrain, for instance depressions.
This problem is solved by the features of the present invention.
By linking the sole plate to the guide plate, the sole plate is reliably guided in any of its positions and therefore clamping of the ski boot sole located on the sole plate is avoided. The support of the invention of the sole plate on the ski furthermore assures reliable fastening of the sole plate and freedom of motion between the sole plate and the ski when the latter bends. The continuous displaceability of the guide plate relative to the base plate fixed in the ski contributes further to that effect.
The step of mounting toe pieces of a safety binding to a sole plate is known, for instance from the Austrian Pat. No. 302,130. However, in this known design, the two toe pieces rest by their base plates directly on the sole plate, and one end of the sole plate is supported in longitudinally displaceably guided manner relative to a fastener fixed in the ski. The other end is rigidly joined to, or hinges on, the other fasterner fixed in the ski. This known embodiment incurs however the drawback that the plate must be continuously spaced from the ski top side between the two bearing places, entailing a greater construction height of the entire assembly. In another known design, disclosed in the German Offenlegungsschrift 34 21 499, the problem is to automatically pivot back, following lateral release, the sole plate both at the front and the rear, together with the toe piece and the heel holder, into the initial position, that is, into the travel position. As such solutions already had long been known from various designs of the state of the art and because the problem basic to the presently cited Offenlegungsschrift is remote from the goal of this invention, the disclosure of said Offenlegungsschrift is even farther afield from the object of this invention than the state of the art cited herein initially. Merely for the sake of completeness, reference is also made to the German Ofenlegungsschrift 34 21 499 and to the French Pat. Nos. 22 79 433; 21 98 762 and 23 05 208.
The present invention provides an especially simple but nevertheless effective design of the displaceable link between the sole and guide plates.
In a manner widely known, the toe piece might be supported directly on the guide plate in longitudinally displaceable manner along the guide rail. However it was found especially advantageous in this application to design the bearing of the toe piece according to another feature of the p
