Abstract
A front jaw having two laterally spaced toggle levers which can be swung out against the force of a release spring housed in a housing and through which housing extends a pull rod. In order to cause in this front jaw during a backward twisting fall an initial tension of the release spring and thus a reduction in the work of the swinging-out toggle lever, the invention provides that the two shorter lever arms of the toggle levers are loaded by a release spring acting through a pull rod onto an angular intermediate lever supported in the lower area of the housing on a first pivot axle.
Claims5
In a front jaw having two pivotally supported, laterally spaced, two arm toggle levers, each having a long lever arm and a short lever arm, said toggle levers each being adapted to be swung laterally outwardly against a force of a release spring housed in a housing fastened to a base plate, and a pull rod extending through the housing, the improvement wherein said two short lever arms of said toggle levers are each loaded by said release spring in said housing acting through said pull rod on an angular intermediate lever pivotally supported in a lower area of said housing on a first pivot axle, said intermediate lever being operable by a pedal arranged on the ski, and wherein said housing consists of first and second parts, of which said first part is fastened to an upper side of the ski, wherein said second part supports said first pivot axle for said intermediate lever, and wherein said two toggle levers are pivotally supported each on a second pivot axle inclined with respect to the upper side of the ski, said second part being pivotal about a third pivot axle extending spaced from the upper side of the ski.
