Definitions

  • ABSTRACT A safety ski binding embodying a release plate intended to be releasably secured to a ski boot.
  • the release plate possesses at one end a supporting surface engaging beneath an associated holding surface of a holder element secured to the ski and the other end of which cooperates with a locking pin subjected to the pressure of an adjustment spring, so that there is possi' ble both lateral release of the release plate as well as also upward release thereof away from the ski.
  • a circular-shaped bearing disc is secured to the ski and engages with a lengthwise extending slot of the release plate, so that the release plate can pivot about the bearing disc, can displace in the lengthwise direction 'with respect to the bearing disc and can be raised therefrom.
  • the supporting surface of the release plate and the holding surface of the holder element form a lateral guide with regard to the axis of the bearing disc.
  • the present invention relates to a new and improved construction of safety or release ski binding embodying a release plate serving for releasable attachment to a ski boot, the release plate having at its one end a supporting surface which engages beneath an associated holding surface of a holder element secured to the ski and the other end of which cooperates with a locking pin which is subjected to the pressure of an adjustment spring, so that there is possible both lateral release of the release plate as well as upward release thereof.
  • Another and more specific object of the present invention relates to an improved construction of releasable ski binding which overcomes, in an effective manner, the previously discussed drawbacks, and wherein the construction of such binding is relatively simple, renders same economical to manufacture, and the binding is extremely reliable in operation.
  • Yet a further significant object of the present invention aims at the provision of an improved construction of safety ski binding which generally is only responsive to the type of forces exerted upon the skiers legs which would require release of the binding, so as to prevent premature release thereof under skiing conditions not warranting initiation of the binding release action.
  • the safety ski binding of this development also referred to as a releasable ski binding, of the aforementioned type, is manifested by the features that a substantially circularshaped bearing disc which is secured to the ski engages with a longitudinal or lengthwise extending slot of the release plate, so that the release plate can pivot about this bearing disc, can displace in the lengthwise direction relative thereto and can be raised therefrom.
  • the supporting surface of the release plate and the holding surface of the holder element form a lateral guide with regard to the axis of the bearing disc.
  • the action of the release forces can be chosen to be more favorable for the different release directions of the binding, and the bearing disc directly contributes to the beneficial result that non-dangerous short-lived impact forces exerted laterally can be absorbed.
  • FIG. 1 is a top plan view of a preferred constructinal embodiment of safety ski binding designed according to the teachings of this invention and shown mounted upon a ski, only a portion of which has been depicted to preserve clarity inillustration and;
  • FIG. 2 is a side view of the safety ski binding arrangement depicted in FIG. 1.
  • a substantially circular ring-shaped shoulder 9 ofthe locking element 5a engages behind a substantially circular ringshaped inner flange 3a at the end of the sleeve 3.
  • a pressure or compression spring 12 is arranged within the sleeve 3 between the piston 8 and an adjustment screw 11 threaded into the sleeve 3. Between the sleeve 3 and the adjustment screw 11 there is inserted a plurality of thin rings 13 by means of which the screw 11 can be fixed in different adjustment positions.
  • the locking pin 5 of the locking element 5a cooperates with a recess 14a provided at a shoulder or projection 14 appearing at the front or's tanding edge 15 of a release plate 16.
  • a sole holder or holddown mechanism 17 At the inside of the upstanding edge 15 there is secured for elevational adjustability, by means of a screw 18 or the like, a sole holder or holddown mechanism 17.
  • threaded bores or holes 19 At the rear end of the release plate 16 opposite the sole holder or holddown mechanism 17, there are provided threaded bores or holes 19 for selectively receiving threaded bolts 20 which are flexed or bent in a manner to form two legs arranged substantially at right angles to one another.
  • Each of the bolts 20 is connected at one respective end, through the agency of a respective threaded sleeve 21, with a respective tension spring 22.
  • Each tension spring 22 is connected through the agency of a respective angled bolt 23 with a sleeve 24 at which there is seated a clamping lever 25.
  • the one arm 25a of the clamping lever 25 is intended to engage over the heel portion of a ski boot 26, as indicated in phantom lines in FIG. 2, and the other arm 25b of which serves as an actuation arm.
  • a substantially circular-shaped bearing disc 28 which engages with a longitudinal or lengthwise extending slot 29 of the release plate 16.
  • the release plate 16 is pivotable about the central axis of the bearing disc 28 and at the same time is displaceable over a limited distance in thelengthwise direction of the ski.
  • the release plate 16 can be raised upwards away from the bearing disc 28.
  • the rear end of the release plate 16 possesses a bevelled or inclined supporting surface 30 extending in a substantially circular arc-shaped fashion with regard to the upstanding central axis of the bearing disc 28.
  • the support or sup porting surface 30 bears against a correspondingly configured substantially circular arc-shaped bevelled holding surface 31 of a holder or holding element 32 secured to the ski 1. Both of the surfaces 30 and 31 extend upwardly and forwardly fromthe bottom towards the top thereof and in the direction of the bearing disc 28, as shown. During lateral release, the release plate 16 is rocked about the bearing disc 28, whereas during a fall towards the front by the skier the release plate is shifted towards the front against the pressure of the spring 12 until the supporting surface 30 no longer contacts or engages with the holding surface 31.
  • the locking pin 5 could be arranged at the rear end of the release plate 16 and the bevelled surface 30 at the front end of such release plate.
  • the release plate 16 can be supported at the bearing disc 28 through the agency of the corresponding end of .the lengthwise extending slot 29 While there is shown and described present preferred embodiments of the invention, it is to be distinctly understood that the invention is not limited thereto, but may be otherwise variously embodied and practiced within the scope of the following claims. Accordingly, what is claimed is:
