  • a spring operated roller in the spring containing housing engages the inner face of a V-shaped guiding surface provided on the rear end of the swivel jaw.
  • the roller is normally disposed in the curved face formedat the apex between the leg portions of the V-shaped guiding surface for holding the jaw in its normal centered position with respect to the baseplate.
  • the spring containing housing is pivotally mounted with its rear end on a vertical pin projecting from the baseplate.
  • the object of the present invention is a front jaw for safety provided with a sole holder overlapping
  • Known front jaws have partially the disadvantage that they loosen too easily, in that a shock is sufficient to release a spring-loaded ball or the like and opens the binding.
  • the new front jaw of the present invention attempts to attain an opening of the binding only after a previously increased resistance has been overcome, and only then the release takes place at once.
  • the new front jaw according to the invention is characterized in this, that a swivel jaw carrying the sole holder is pivotally connected at its front end with a spring housing and atits rear end with two downwardly projecting continuations is guided laterally slidably over a limited path on a baseplate fixedly secured to the ski, whereby the spring housing contains a spring-loaded roller, which cooperates with a guide face of the swivel jaw facing it and aims at holding the same in its center position, whereby this guide face is formed by two surface portions disposed at an angle to one another, and that the spring housing on its part is pivotally at its rear end about a pin fixedly secured to the baseplate.

  • Above the baseplate 4 is disposed -on the rear-in the drawing on the left-hand side of the spring housing 8a recess 9, whose vertical wall 9' (FIG. 3) is curved according to an arc of a circle. The center point of this are lies in the axis of a vertical bolt 17 secured to the swivel jaw 14 still to be described, which bolt enters with its lower end into a corresponding bore in the upper side ofthe housing 8.
  • a sleeve 19 In a horizontal central bore 18 of the spring containing housing 8 is slidably guided a sleeve 19, on one end of which by means of a vertical pin 20 a roller 21 is rotatably mounted.
  • a pressure spring 22 extending into the sleeve 19 aims at pressing the sleeve 19 and therewith the roller 21 backwards, that is, to the left in the-drawing.
  • This spring 22 engages, on the one hand, a transverse wall in the sleeve 22 and, on the other hand, a disc 24 outside the sleeve.
  • the disc 24 is seated on the threaded spindle 25 and carries a radially projecting pin 24', which is slidable in a slotlike window 26 of the spring housing 8.
  • the disc 24 By means of rotating the threaded spindle 25 which has a slotted head and which is accessible from the outside, the disc 24 may be axially adjusted and therewith'the effective pressure of the spring 22 be changed.
  • the pin 24' projecting into the window 26 serves at-the same time for indication of the spring tension.
  • the head of the threaded spindle 25 rests on a cap 27 threaded into the front end of the central bore 18.
  • the spring containing housing 8 is covered by a swivel jaw 14.
  • the swivel jaw 14 enters with its bolt 17 mentioned above into the bore in the upper side of the spring housing 8.
  • the swivel jaw 14 comprises an upper cover plate 15 to.which the mentioned bolt 17 isriveted, and a curved jaw 16 disposed rearwardly (to the left in the drawing), which is provided on its rear side with a series of vertical horizontally extending teeth 32 (FIG. 7).
  • a sole holder 30 is provided on its side facing the jaw 16 with corresponding teeth 31 (FIG. 2) which engage the teeth 32 and may be fastened by means of the screws 35 at different positions as to height.
  • the front ends of the screws 35 enter thereby into vertically disposed cylindrical holders 34, which are slidably disposed in vertical bores 33 of the jaw I6. Slots 36 in the jaw 16 make the passage of the screws 35 possible and insure a vertical adjustability of the sole holder 30 on the
  • the swivel jaw 14 has below the cove plate 15 approximately vertically extending guide faces 23 (FIG. 2) for engagement with the roller 21, arranged set back in relation to the bolt 17.
  • This guide face 23 is V-shaped and comprises two surface parts extending at least approximately at a right angle to one another, which meet in the longitudinal axis of the swivel jaw 14 over a curve, in which latter in the rest position of the front jaw shown in FIG. 2, the roller 21 is disposed.
  • the swivel jaw 14 has behind its part having the guide face 23, downwardly projecting lateral continuations 40. The latter lie with their front faces 39 (FIG. 5) against the rear edge 38 of the baseplate 1.
  • a holddown plate 10 is fixedly connected by means of screws 13 with the swivel jaw 14.
  • This holddown plate 10 is arc-shaped on its front side and, indeed, the arc of the same corresponds to the above-mentioned vertical wall 9 of the recess 9.
  • the holddown plate 10 enters into this latter recess and prevents thereby an undesired raising of the swivel jaw 14.
