Definitions

  • ABSTRACT A safety ski binding embodying a release plate intended to be fixedly retained at the ski boot and which can be locked with the ski through the agency of locking pins.
  • at the region of at least one end of the release plate there are provided two locking pins disposed adjacent one another to both sides of the central lengthwise axis of the associated ski, these pins cooperating with recesses provided at the relevant end of the release plate in such a manner that during sideward release of the release plate only always one of both locking pins comes into operable play, yet upon loading the release plate towards the top and in the lengthwise direction of the ski both locking pins come into play.
  • the present invention relates to a new and improved safety ski binding incorporating a release plate intended to be fixed to the ski boot and which can be locked by means of locking pins at the associated ski.
  • Another and more specific object of the present invention relates to the provision of a novel safety ski binding ensuring for positive release of the foot of the skier from the binding when encountering circumstances where it is desired for such release action positively to occur.
  • Still a further significant object of the present invention relates to a novel safety ski binding which is relatively simple in construction, economical to manufacture, easy to adjust, requires a minimum of maintenance, and affords good safety release action between the foot of the user and the ski when encountering skiing circumstances which warrant release of the skiers foot from the ski.
  • the safety ski binding of this invention is provided at least at one end of the release plate with two locking pins which are arranged adjacent one another and to both sides of the central length-wise axis of the associated ski.
  • These locking pins cooperate with recesses or depressions provided at the relevant end of the release plate in such a manner that during sideward release of the release plate only one of both locking pins is effective, but upon loading the release plate towards the top and in the lengthwise direction of the ski both such locking pins are effective There can thus be obtained a more favorable behavior of the release forces.
  • both locking pins can be adjusted differently in respect of the loading thereof so as to have different effective actions, in order to accommodate such to different loads which are encountered when twisting in the one or the other direction or to the different loads encountered during skiing, for instance when skiing down a slope or when snow ploughing.
  • the lateral tilting release and combined release is improved and the release plate itself is pressed against the ski at a number of locations.
  • a release plate 2 is locked at the ski 1 through the agency of two similar locking mechanisms 3 and 4.
  • the respective housings 5 of each such locking mechanism 3 and 4 are attached by means of two respective screws 6 or other fastening expedients with the body of the ski 1.
  • Each such pressure spring 9 bears against an adjustment screw 10, by means of which it is possible to adjust individually, for each pin 7, the pressure exerted thereon by the associated pressure spring 9.
  • the semi-spherical shaped terminal portions 8 of the locking pins 7 engage with appropriate recesses 11 provided at an associated neighboring upright or upstanding marginal portion 12 at each end of the release plate 2. Between both these recesses 11 located at each marginal portion 12 there is provided a projection in the form of a run-on or contact surface 13 and beneath such a further projection in the form ofa bevelled or chamfered portion 14.
  • For engaging the release plate 12 it will be understood that one end is placed upon the ski 1 and pushed against the associated locking pins 7 until the end portions 8 thereof enter into the recesses 11 provided at the corresponding marginal edge 12.
  • a sole holder 15 At the front edge 2 of the release plate 2 there is secured a sole holder 15 by means of a screw 16 or equivalent attachment device.
  • the sole holder 15 is provided with two downwardly directed cams or dogs 17 which bear against the neighboring marginal edge 12 and positionally fix this sole holder or sole retaining element 15.
  • the ski boot 18 shown in phantom lines, is fixedly held at its front region against the release plate 2.
  • this clamping lever arrangement 19 At the rear end of the ski boot such is fixedly held against the release plate 2 through the agency of a clamping lever arrangement 19, this clamping lever arrangement 19, when in its tensioned state, acting upon the heel of the ski boot l8 and being pivotally connected in conventional fashion with the release plate 2 through the agency of connecting elements 20 and the tension springs 21.
  • the locking mechanism instead of being equipped with the axially displaceable locking pins, could also have locking pins which could be rocked or'pivoted to all sides and which then cooperate with appropriate recesses provided at the release plate, again similar to an arrangement disclosed in the aforementioned Swiss Pat. No. 443,089.
  • a safety ski binding for both lateral and vertical release actions comprising a release plate including means for fixing a ski boot thereto, means on the ski adjacent the front and rear ends of the plate for releasably locking the release plate to the ski, said release means including, said locking pin means comprising only two spring-loaded locking pin members arranged in the region of one end of said release plate adjacent one another and positionable on both sides of a central longitudinal axis of the associated ski, one of said two spring-loaded locking pin members solely participating in the lateral release action of the ski binding to one side and the other of said two spring-loaded locking pin 'members solely participating in the lateral release action of the ski binding to the opposite side, both of said two spring-loaded locking pin members participating in the vertical release action of the ski binding, said re lease plate including an end portion confronting said locking pin members for cooperating therewith to releasably lock the plate and the ski, said confronting end portion of said release plate including two projections, a first of said projections engaging beneath both of the locking pin members for
