Definitions

  • ABSTRACT OF THE DISCLOSURE a spring holds the detents or pawls in position. When an excessive lateral thrust is experienced, the detents or pawls are caused to release from the cutouts, and one of the jaw members can slide out to the side, releasing the ski boot.
  • each lateral jaw remain tied to the ski after the release by a short wire cable.
  • the latching devices can consist of detents, effective between the ski or the component attached to the ski on one side and the receiving plate on the other, which are released as soon as a predtermined lateral force has been exceeded. In that case the release of the lateral jaws is solely forcecontrolled.
  • the receiving plates may also be insertable in guiding devices on a foot plate pivoted on a center in the vicinity of the ski boot heel and rotatable to a limited extent against a spring force.
  • the limited motion of such a foot plate against the opposing spring force permits the absorption of minor lateral forces which are not so strong that they might cause a leg injury and which, therefore, do not have to bring about a release of the safety binding.
  • Latching devices built to function together with the receiving plates can be provided on the foot plate in order to be released as soon as the foot plate swivels by a certain angle. As soon as that swivel range of the foot plate is exceeded which corresponds to safe lateral forces, the release, in this case deflection-controlled, of the corresponding lateral jaw takes place, causing it to slip out of the guide and freeing the foot.
  • FIG. 1 is a top plan view, with the cover plate omitted, of a lateral-jaw safety binding according to this invention, on which the release is controlled by force.
  • FIG. 2 is a sectional view of the embodiment in FIG. 1, taken along line 22 of FIG. 1.
  • FIG. 3 is a top plan view of an embodiment in which the release is controlled by the amount of deflection, one half of the binding being shown without cover plate.
  • FIG. 4 is the same embodiment as in FIG. 3 with the lateral jaw which is shown on the right in the drawing having been released and the cover plate for the whole binding omitted.
  • FIG. 5 is a sectional view along line 55 of FIG. 3.
  • the lateral jaw parts 4 and 4' consist of the receiving plates 5 and 5 with raised serrations 6 and 6'. These serrations 6 and 6' are of circular shape and the lateral angles 7 and 7 are adjustably fitted to them.
  • the screws 8 and 8 guided in the slots 9 and 9', are holding the lateral angles '7 and 7'.
  • the shape of the lateral angles 7 and 7' and their angular and lateral adjustability permit adaptation to a boot of any shape.
  • slots 11 may be provided for a toe thong not shown on the drawing.
  • Detent notches 12 and 12' are provided in the receiving plates 5 and 5 of the lateral jaws 4 and 4'.
  • the detents 13 and 13' are engaging in the detent notches 12 and 12',
  • the spring 14 is exerting pressure on the detents 13 and 13 which are pivoted on the fixed bolts 15 and 15'.
  • the spring 14 rests against the cam 16 with which the spring pressure and thereby the release force is adjusted.
  • the cam 16 has an operating lever 17 and can be rotated on the rivet 18. If in case of a sidewise fall the force acting laterally in the direction of arrow 19 becomes greater than the detent resistance, the detent 13 due to its slanted sliding surface is forced out of the detent notch 12 whereby the lateral jaw 4 and the boot, respectively, are released.
  • a stop 25 is installed which limits the travel of the detents 13 and 13'.
  • the foot plate 26 is pivoting on a center 27 in the vicinity of the heel on the ski 28.
  • the whole lateral jaws 4 and 4' are built exactly like in the embodiment of the FIGS. 1 and 2. They too are inserted like drawers in the rectangular openings formed by the foot plate 26, its raised sections 2 and the cover plate 29.
  • the detent notches 30 and 30' in the lateral jaws 4- and 4 are preferably arranged on the sides toward the end of the ski.
  • the detents 31 and 31 are engaging in these detent notches and are in this case preferably sliding parallel to the center line 32 of the foot plate 26.
  • FIG. 4 shows, a swivel motion of the foot plate 26 compresses one of the helical springs 39 or 39, respectively, which are placed around the guide rod 47. If the deflection angle 38 is not reached, the compression springs 39 or 39', respectively, will return the foot plate 26 to its center position. In this manner the compression springs 39 and 39 can absorb minor lateral shocks and allow a determinable swivel range. The force required for the release is adjusted on the knurled screws 41 and 41, respectively.
  • the boot After the release of one of the lateral jaws 4 and 4' the boot is automatically disengaged and the released lateral jaw 4 or 4' remains attached to the steel cable 21 or 21.
  • the lateral jaw For insertion of the lateral jaw into the rectangular opening of the foot plate 26 the latter is turned outward and returned to the center position with the lateral jaws 4 and 4 inserted.
  • the detents 31 and 31 will now again slide along the cam 36 until they are engaged in the detent notches 30 and 30'. At and around the cam 36 there is an opening in the foot plate so that its motions will not be impeded by the cam.
  • the detents 31 and 31 are guided by the slide 42 in slots 43 of the cover plate 29.
  • the torsion spring 33 is placed around the bolt 44.
  • a safety ski binding having lateral jaws for engaging the forward portion of a ski boot in which an excessive lateral force on said binding will cause the lateral jaw to release the boot in the direction of the force
  • said ski binding comprising two lateral jaws each connected to a horizontal receiving plate and extending approximately to the longitudinal center line of the ski, a guiding device arranged essentially crosswise to the longitudinal direction of the ski into which each said receiving plate is slidably inserted, latching means in said guiding device, said latching means detachably securing said plates in said guiding device in the inserted position, said plates being completely withdrawable after the latching means has been tripped by application of an excessive lateral force.
  • a safety ski binding according to claim 1 in which a short wire cable is provided to connect each lateral jaw to the ski after release of said binding.
  • a safety ski binding according to claim 1 in which said latching device comprises detents in said receiving plates, adjustable detent engaging means in said guiding device, said detent engaging means being set to release when a predetermined lateral force is exceeded.
  • a safety ski binding according to claim 1 in which said receiving plates are insertable in guiding device portions of a foot plate, said foot plate being rotatably mounted to a limited extent against a spring force preferably about a pivot axis in the vicinity of the heel of the ski boot.
  • a safety device in which said latching device releases when said foot plate rotates to a certain angle.
  • a safety ski binding according to claim 1 wherein said guiding device is rotatably mounted on the ski about a pivot axis in the vicinity of the ski boot heel, additional guide means are mounted on said ski crosswise to the longitudinal direction of said ski, said guide means includ- 6 ing a front extension which slidably moves along said FOREIGN PATENTS additional guide means, and spring bias means being 145 539 5/1936 Austria mounted on said guide means to bias said front extension 1 126948 8/1956 France" to a neutral position and to be deflected by said front 191259 8/1937 Switzerland extension during a swivel movement of said guide means. 5 2o7087 12/1939 Switzerland:
