BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a front jaw.
BACKGROUND OF THE INVENTION
Such a front jaw has, for example, been described in EP-A2 0 408 855.
The technical solution disclosed in this reference has proven to be successful, however, the desire exists to further improve this front jaw since the penetration of snow and dirt on the side facing the ski shoe is supposed to be prevented as much as possible.
It has already been suggested to build a ski binding with a housing closed on all sides (see DE-OS 19 38 567). However, this solution has the disadvantage that the structural possibilities with respect to the directions of movement are very limited. Such a solution is, therefore, out of the question for a front jaw with toggle levers of this type.
It is furthermore known from DE-OS 21 61 881 to close off the open spaces between movable ski binding parts and the ski binding housing with a bellows. This solution was not successful in reality since such bellows could not withstand the rough operating conditions of a ski binding. Furthermore, such bellows are only suited for simple designs.
SUMMARY OF THE INVENTION
The goal of the invention is to avoid these disadvantages and to protect a front jaw of the above-mentioned type in a simple manner against the penetration of dirt and snow.
This purpose is attained according to the invention by the characterizing characteristics of claim 1. Due to the fact that an approximately vertically upwardly projecting cover plate is connected to a path-defining means for the release plate, which path-defining means is arranged on the housing of the ski binding, the upper end section of which cover plate is bent forwardly at least in certain areas, the ski binding is protected against the penetration of dirt and snow on the side facing a ski shoe to be inserted.
An elastic insert by itself is known from DE-OS 37 42 483. However, this known solution has the disadvantage that, on the one hand, the elastic insert has a complicated shape and that it, on the other hand, can be easily damaged by outside mechanical influences (ice, stones, steel edges).
It has proven to be particularly advantageous when the insert consists of a foam material, preferably of a closed-cell polyethylene foam material.
BRIEF DESCRIPTION OF THE DRAWINGS
Further advantages, characteristics and details of the front jaw of the invention will now be described in greater detail in connection with the drawings, in which:
FIG. 1 is a top view of parts of the front jaw of the invention,
FIG. 2 is a longitudinal central cross-sectional view of the front jaw in the position of the ski binding, in which it is ready to be stepped thereinto, and
FIG. 3 is the same view with an upwardly pivoted sole holder.
DETAILED DESCRIPTION OF THE INVENTION
FIGS. 1 and 2 show the front jaw 1 of the invention in the position in which it is ready to be stepped thereinto. Individual parts, which are without any importance for the present invention, have thereby only been schematically indicated or were left out for the purpose of a better clarity. The front jaw 1 has a housing 2 which is fastened on a ski 50 by means of screws 51 (only schematically indicated). A release spring 40 is housed in the housing 2, the initial tension of which release spring can be adjusted in a conventional manner by an adjusting device 43. The release spring 40 is arranged between a spring plate 41 and, with the interpositioning of a bearing sleeve 42, a vertically extending rear crosswall 3 of the housing 2. A pull rod 10 extends in axial direction through the release spring 40, the one end 11 of which pull rod cooperates with the adjusting device 43 and the other end 12 of which pull rod is connected to an essentially vertically extending release plate 13. The release plate 13 has at its lower end 14 a control surface 15 directed toward the tip of the ski and a stop 16 pointing rearwardly in direction of a ski shoe to be inserted.
The vertically extending rear crosswall 3 of the housing 2 is followed at the top by a first curved
