BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a front jaw.
BACKGROUND OF THE INVENTION
Such a front jaw is described, for example, in EP-A2 0 408 855. In this known solution, both the relief of the toggle levers during upwardly acting forces and also the release movement of the jaw during a backward twisting fall is accomplished by a tilting of a bearing part relative to the jaw housing. The sole down-holding means is adapted to the respective shoe sole thickness by moving the bearing part along the rear crosswall of the jaw housing, with additional sloped surfaces being provided for this purpose on the housing and bearing part.
This solution is by all means practical, however, friction occurs inevitably at the contact surfaces during movement of these structural parts.
A slightly different front jaw is known from DE-OS 37 34 492, in which the sole holder is adjusted and relieved also by a movement, namely along a sloped surface of the housing. The already abovementioned disadvantage is thereby created.
An object of the invention is to bring help mere and to provide, in a front jaw of the abovementioned type, a mechanism for facilitating an automatic adaptation of the front jaw to the respective shoe sole thickness so that as little as possible friction will occur.
SUMMARY OF THE INVENTION
Due to the fact that with an essentially vertically extending rear crosswall on the housing, the frontwardly facing bearing surface of the bearing part has two adjacent sections in elevational direction, namely, a lower section and an upper section which define an obtuse angle with one another whereat a pivot edge is created and about which the bearing part can be pivoted to facilitate adaptation to the shoe sole.
The development enables, after utilizing the pivoting movement made possible by the pivot edge, a further pivoting of the bearing part for effecting a binding release.
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 partially sectioned elevational top view of the front jaw,
FIG. 2 is a longitudinal cross-sectional view of the front jaw in a position of the ski binding which is ready to be stepped into by an indicated ski shoe,
FIG. 3 is an illustration similar to FIG. 2, with an inserted ski shoe, with a thick sole,
FIG. 4 is the same view with a slightly more swiveled sole holder,
FIG. 5 shows the binding with the sole holder being pivoted to its maximum extent, and
FIGS. 6 and 7 are partially sectioned rear views, with the binding in FIG. 6 being shown in an at-rest position and in FIG. 7 laterally upwardly swiveled.
DETAILED DESCRIPTION
FIGS. 1 and 2 illustrate a front jaw 1 embodying the invention in a position in which it is ready to be stepped into. It has a housing 2 which is fastened to a ski 50 by means of screws 51, which are 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 support sleeve 42, a vertically extending rear crosswall 3 of the housing. A pull rod 10 extends in axial direction through the release spring 40, one end 11 thereof cooperating with the adjusting device 43 and an other end 12 being connected to an essentially vertically extending release plate 13. The release plate 13 has at its lower end 14 a control surface 15 facing toward the tip of the ski and a stop 16 pointing in direction of the shoe 60.
A first curved surface 5 is provided at the juncture of the top of the vertically extending rear crosswall 3 of the housing 2 and a horizontally rearwardly extending section 6. A bearing part 20 having a support wall 22 rests on the backside 4 of the rear crosswall 3 of the housing 2 in a position of the front jaw 1 ready to be stepped into. The bearing part 20 has, viewed from the
