BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a front jaw which prevents dirt from penetrating into a housing from above.
BACKGROUND OF THE INVENTION
Such a front jaw is, for example, described in EP-A2 0 408 855.
The goal of the invention is to further improve this front jaw and, in particular, to keep dirt from penetrating into the open areas necessary for the movement of the holding plate.
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 61 861 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.
The invention has therefore the goal to avoid these disadvantages and to protect a front jaw of the abovementioned type in a simple manner against the penetration of dirt from above. The designer should have at the same time greater freedom regarding material selection.
SUMMARY OF THE INVENTION
This purpose is attained according to present the invention. Due to the fact that following the rear crosswall of the housing there is arranged an insert plate extending vertically and essentially resting on the crosswall, on which plate rests in certain areas the front support surface of a support part, with the approximately horizontally rearwardly extending section following the plate at its upper section in an area adjacent to the longitudinal axis of the ski, the designer can select a suitable material for the plate independent from the housing. Due to the fact that upper side parts of the plate each have a section of a thin material thickness and a following section of a thicker material thickness, the open spaces needed for the movement of the support parts are closed off in an upward direction, with the first sections of a lesser material thickness being so flexible that the movement of the support parts is not influenced. The development enables a reliable bearing of the second section of the upper side parts of the plate on the support part even under unfavorable conditions.
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 the drawings, in which:
FIG. 1 is a longitudinal central cross-sectional view of the front jaw,
FIG. 2 is a fragmentary elevational top view thereof,
FIGS. 3 and 4 are an elevational view and a cross-sectional view respectively taken along the line IV--IV of the insert plate, and
FIGS. 5 and 6 show a detail in an enlarged scale taken along the line V--V in FIG. 3.
DETAILED DESCRIPTION
FIGS. 1 and 2 show the front jaw 1 of the invention in a position ready for stepping thereinto. FIG. 2 illustrates thereby for better clarity the parts not important to the invention only by dash-dotted lines. The front jaw 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 release spring 40 is supported with its rear end on a vertically extending rear crosswall 3 of the housing 2. A pull rod 10 extends in axial direction through the rear crosswall 3. The rear end 12 of the pull rod 10 is connected to an essentially vertically extending release plate 13.
The vertically extending rear crosswall 3 of the housing 2 is followed at the top by a horizontally and rearwardly extending section 6. An insert plate 100 rests on the rear crosswall 3 of the housing. The insert plate 100 can be better recognized in FIGS. 3 and 4. It extends essentially vertically. A curved section 102 follows its upper section 101 in the area adj
