A safety ski binding comprises a swingable plate 6 the forward portion of which is provided with lateral jaws 13, the swingable plate being pivotally mounted to swing about an axis located in the region of the heel and extending perpendicular to the upper side of the ski, the forward end of the swingable plate being adapted to be held in its central position by a detent device 5 adapted to be released upon the application of a torque exceeding a predetermined value, wherein the lateral jaws are provided on a jaw plate 15 which is pivotally mounted on the forward portion of the swing- able plate and which is held against rotation when the swingable plate is in its central position, the positive engagement of the locking members being interrupted upon a swinging movement being imparted to the swingable plate. The plate 6 has an elongated aperture 8 in which engages a bearing disc 9, on the ski, a flange on the disc engaging a shouldered edge of the aperture. The plate 6 is pivotally connected to a retaining member 3 pivoting on an axis 4 on a base plate 2 and locked in central position by a spring bolt detent device 5. The pivoting jaw plate 15 is locked in central position by a lug 15a on the jaw engaging a recess 3a in the retaining member 3. The retaining member has a toe hold down element 14 and the jaws may be mounted for adjustable spacing. Modifications comprise a flat retaining member 3 with a downwardly acting detent device 5 or a lever upwardly bent at the forward edge and retained in central position by a horizontally acting detent device, the lug 15a engaging in a recess in the retaining member pivotally mounted on the lever which pivots on a base plate secured to the ski, the retaining member having two studs which engage in elongated slots in the plate 6. The plate may have a pin which engages in an arcuate slot in the retaining plate fixed to the ski and retained in central position by a detent device or the detent ball may engage in an arcuate slot in the plate. The hold down elements 14 may be vertically adjustable. A toe hold down member may be adjustably mounted on a screw or supporting angle plate, the base may have a thread which adjustably engages a complementary thread on the plate 6. The jaw plate may be mounted on the plate 6 and retained with one rectilinear edge engaging an edge of a plate fixedly secured to the ski over the plate 6, the jaw plate being released to rotate when the plate 6 moves longitudinally or a hook on the ski may engage a recess in the rear edge of the jaw plate or a rod pivoted on the pivot of the plate 6 may engage a cut out at the rear edge of the jaw plate. |
