Definitions

  • ABSTRACT F THE DISCLOSURE A safety ski binding in which a swivelling arm carrying a clamping jaw adapted to engage wit-h the sole of a ski boot is pivotally supported on a raised surface portion of the base plate, which is provided with a longitudinally extending guide slot in the raised surface portion through which extends a guide and pivoting screw or bolt engaging in the swivelling arm; the raised surface portion is provided forwardly of the guide slot with a latching aperture into which engages a similarly-shaped latching member extending from the swivelling arm; the latching member is spring-loaded by means of an adjustable pressure spring, contained within a hollow threaded element.
  • the latching aperture is of almost semi-circular configuration with the straight surface portion facing forwardly while the latching member is provided with a forwardly facing straight portion and rounded-off portions opposite the straight stop surface portion.
  • the invention relates to a safety ski Ibinding with a clamping jaw at the end of a swivel arm carried laterally slewable and longitudinally movable, engaging the front edge of the sole.
  • a safety ski binding of this nature has a swivel arm which is connected by guides with the base plate fixed on the ski in such manner that when a higher torque occurs, it is lifted off from its seat and pushed forward.
  • a safety ski binding has already been known with two closed coulisses outside of the longitudinal middle whereby the swivelling disc supporting the clamping jaw is provided with two spaced fingers catching the said coulisses.
  • the two lingers catching in the said coulisses constitute at times when the clamping jaw is swivelled the rotation axis of the one or other side whereby t-he centers of rotation lie outside of the longitudinal middle of the ski binding.
  • Such a ski binding allows a lateral swing of the clamping jaw, but not the moving in the longitudinal direction.
  • the novelty of the safety ski binding as per the present invention which is provided with a clamping jaw engaging the front edge of the ski boot and being at the end of a laterally slewable and longitudinally movable swivelling arm, consists in that the base plate supporting the swivelling ar-m is provided in its longitudinal middle with a raised surface plate having a guiding slot for the swivelling arm and extending in the longitudinal direction.
  • the surface plate is equipped with a latch opening or aperture for the corresponding latch tongue provided in front of the swivelling arm.
  • This construction achieves that after a relatively slight lateral swing the swivelling arm is free to swing out to the right or left, gliding forward at the same time.
  • the surface plate for the swivelling arm is embossed from the base plate.
  • the surface plate for the swivelling arm has most suitably an oval form, with a latch at its front end.
  • the drawing shows an example of embodiment of the invented object, i.e.:
  • FIG. 1 a top plan view 0f the safety ski binding in the normal position of use
  • FIG. 2 a top plan view of the safety ski binding with the clamping jaw swivelled out
  • FIG. 3 a section along the line I-I of FIG. 1, and
  • FIG. 4 a view of the safety ski binding from below.
  • the safety ski binding illustrated in the drawing designates by reference numeral 1 the base plate which is fixed with screws 2 unto the ski not shown on the drawing.
  • the base plate 1 has at its longitudinal middle an embossed surface plate 3 directed upwards, and which is provided with a longitudinal slot 4, where the bolt of the screw 5 (FIGS. 3 and 4) finds its guide.
  • the embossing of the surface plate 3 is chosen at such a depth that the head of the screw 5 can move without hindrance.
  • the said ernbossing forms on the base plate 1 a surface plate for the swivelling arm 6, which latter is connected through the screw 5 in a rotating and longitudinal moveably manner with the base plate 1.
  • At the front end of the swivelling arm 6 is fastened the clamping jaw 8 by means of the screw 7.
  • the surface plate 3 has on its opposite end to the clamping jaw 8 a tapered extension 9, as shown in FIG. 4, which is provided in the shown example with an almost semicircular opening 10, destined to receive the correspondingly formed pin-like latching member 11 (FIG. 3) which on one of its longitudinal sides is provided with a stop face 11 and on its opposite lower end with a rounded-olf 11".
  • the pin-like latching member 11 is under the influence of the pressure spring 12 (FIG. 3) which is embedded within the hollow adjusting screw 13, as shown in FIG. 3.
  • the described safety binding according to the present invention possesses the advantage of being of an extraordinary simple and sturdy construction and being capable of being manufactured at a favorable price.
  • a safety ski binding having a clamping jaw at the end of a swivelling arm which is laterally slewable and longitudinally movable and adapted to engage the edge of the sole of a ski boot
  • the improvement comprises a base plate, pivot means pivotally supporting the swivelling arm on said base plate, said pivot means including a single pivot pin, a plate portion, and a single longitudinally extending guide slot for the pivot pin, and a single latch means for latching the swivelling arm in normal skiing position relative to the base plate, the swivelling arm being free of engagement with any restraining surface other than said single latch means and the pivot pin in normal skiing position and in the slewed position being rotatable about the pivot pin in any direction without requiring longitudinal motion of the swivelling arm
  • said latch means essentially consisting only of an aperture provided in the front end area of the plate portion and of a reciprocally movable latching member for latching the swivelling arm to the base plate, said aperture being semi
  • a safety ski binding according to claim 2 further comprising an adjustable pressure spring acting on said latching member.
  • a safety ski binding according to claim 6 wherein said plate portion is provided at its end opposite the clamping jaw with a tapered extension accommodating the latch aperture.
