  • Front jaws of the type known from prior art which are particularly appropriate for children are of such constructive design that the entire housing can rotate with the sole holder about a vertical axis and as a result of this rotation releases the ski boot if a danger occurs. Due to the total rotation of housing and sole holder. higher spring forces are required. as is well known. said forces being substantially higher. since the lever effect between the pivoting point in the housing and the point of contact of the ski boot can be compensated only by stronger and thus more expensive springs. particularly if a longitudinal stroke (good absorption of energy) is to be accomplished.
  • front jaws are known having a stationary housing. wherein the sole holder coacts directly with the bolting which consists of a spring-loaded plane surface or a serration. This is both expensive and operationally unsafe.
  • the object of the present invention is to provide a jaw of the initially mentioned kind. which in spite of its simple structure releases in any event the ski boot if it is subjected to a lateral pivoting in a troubleproof manner. which is not functionally short-stroked and which after accomplished release automatically resets into the starting position. which is a prerequisite for a good absorption of energy.
  • this object is achieved in that the part of the sole holder located in the housing is connected with an engagement bearing positioned in the housing. pivotable about the continuous vertical shaft. said bearing coacting with a bolting provided with a spring-loaded ball positioned in the housing.
  • the sole holder is to be adjustable in relation to the engagement bearing. in vertical direction. That way different heights of soles of ski boots can be taken into account in a perfect manner.
  • the vertical shaft is designed as a threaded spindle on which the part of the sole holder provided with an internal thread is positioned in a vertically adjustable manner.
  • the spring impingement of the ball is adjustable, so that the release tension can be varied. depending on the requirements prevalent in practical operations.
  • the spring may impinge on the ball on the one hand. and on an adjustment member operable from the outside and positioned in the housing. on the other hand.
  • the adjustment member is provided with a flange impinged by the spring which is designed multi-stepped on the opposite side coacting with the inside wall of the housing. wherein the flange is followed by an externally operable pin.
  • the adjustment member to be is an externally operating adjustment screw. so that again a variation of the tension of release results in a simple manner.
  • FIG. 1 shows a side view of a front jaw according to the invention. in section:
  • HO. 2 shows a plan view upon the front jaw according to FIG. 1. partially in section.
  • the front jaw comprises a housing 1 which is fixedly screwed to the ski via a bottom plate 15 and two screw apertures 16.
  • An engagement ball 5 is placed within the housing and positioned in a partition 17 thereof. The engagement ball 5 is impinged by a spring 7.
  • an engagement bearing 4 provided with a recess 9 is arranged inside the housing.
  • the ball 5 partially engages the recess 9 which may have a truncated-cone-configuration.
  • the engagement hearing 4 is designed semi-circular on the one hand and positioned with this semi-circular form within the stationary housing 1.
  • the engagement bearing 4 is provided in addition with a U-shaped recess.
  • a part 8 of the sole holder 2 engages said recess. Said part 8 of the sole holder 2 is thus positioned within the housing I.
  • the sole holder 2 is pivotable about a vertical shaft 3.
  • the same pivoting shaft also is included with the engagement bearing 4. because the center of the semicylinder of the engagement bearing 4 and the pivotal point of the sole holder 2 are placed concentrically.
  • the vertical shaft 3 is advantageously designed as a threaded spindle 10.
  • This threaded spindle 10 is positioned fixedly within the housing 1.
  • the sole holder 2 extends with its part 8 into the U- shaped recess of the engagement bearing 4. This provides for a possible vertical adjustment.
  • the threaded spindle 10 is rotated. for example by means of a screw driver or a coin. the result is a vertical adjustability of the sole holder 2 provided with an internal threading. which is positioned on the threaded spindle 10.
  • the sole holder. pivots according to FIG. 2 either to the left or to the right. whereby at the same time the engagement bearing 4 likewise pivots about the vertical shaft 3. and the sphere 5 is urged out of the recess 9.
  • This adjustment may be so designed. for example. that the spring impinges the ball 5 on the one hand and a flange ll of an adjustment member 6 on the other hand.
  • This adjustment member 6 shows on the opposite side 12 of the flange 11 two steps for example. according to FIG. 2. Both steps may coact with the inside wall 13 of the housing. which also is of a two-step design. If now the pin 14 of the adjustment member projecting out of the housing I is urged in the direction of the arrow 1 and rotated by 180. another step of the multi-step opposite side 12 abuts to the multi-step inner housing wall 13. which results in a modification of the compressed spring 7. This modification of the compressed spring 7 is transferred to the engagement ball 5 as a modified release tension.
  • the present invention offers a frontjaw for safety bindings of simple design and of very high In that case. the sole holder pivotable about a vertical shaft grips the heel of the ski boot (not represented in detail).
  • a jaw for a safety ski binding comprising a housing including:
  • locking means comprising a spring-loaded ball in cluding means for adjusting the load thereof.
  • an engagement bearing and a portion of the hous- 7 justment member including an adjustment pin inner wall of the housing. a portion of the pin projccti ng out of the housing and being operable from the outside.
