Definitions

  • the present invention relates to front jaws for safety ski bindings according to the first part of the main claim.
  • Such front jaws are known for example from DE-A1-33 43 943. Compared to more known front jaws, these have the advantage of extremely low internal friction and thus a better resetting behavior than the more known front jaws.
  • the extensions of the side jaws are coupled together via two intermediate levers, the two-armed lever provided for securing the normal position of the side jaws and forming a locking part being operatively connected to the intermediate levers.
  • the two-armed lever In order to influence the two-armed lever, at least one special control part not assigned to the four-bar linkage is provided.
  • the purpose of the present invention is therefore to simplify the design of the generic front jaws by avoiding parts that were previously present and thus to make them even less sensitive to faults.
  • the end faces of the free ends of the lever adjoining the curve sections expediently form blocking surfaces for the extensions of the side jaws.
  • the adjoining edge part of the lever is concavely curved and serves as a restoring surface for the extension of the respective side jaw.
  • a base plate 1 which is to be mounted in a ski-tight manner in the usual way, has a four-bar linkage with levers 4 and 5 and a coupling 6 on two axes 2, 3 extending at right angles to the ski plane.
  • the coupling serves as a support member for two side jaws 7, 8, each on one the pivot pin 9, 10 of the coupling are mounted on the levers.
  • the side cheeks supporting the shoe sole laterally and forwards extend inward beyond their pivot pins 9, 10.
  • the free ends of the arms 11, 12 thus formed normally rest on a two-armed lever 13 mounted axially parallel to the side jaws on the support member, so that the side jaws 7, 8 are held immovably with respect to the support member.
  • the support member 6 has a locking recess 14 on the inside, in which a locking roller 15 is supported, which is under the influence of a helical compression spring 16, which in turn is supported on the base plate 1.
  • the locking roller normally holds the support member and thus the four-bar linkage in the position shown in FIG. 1.
  • the latching resistance can be varied in a known and therefore not further described manner by changing the pretension of the helical compression spring.
  • the locking roller is guided relative to the base plate in a manner which is also known and therefore not shown.
  • the arms of the lever 13 mounted centrally on the axis 17 on the support member 6 are of mirror-like design.
  • the end faces of the free ends of the lever each form a blocking surface 18 or 19 for an arm 11 or 12 of the associated side jaw.
  • the lever 13 has a concave curve on the inside of the jaw, which corresponds in its central region 20 to the locking recess 14 provided on the support member 6.
  • the sections 21, 22 adjoining this area on both sides jump forward relative to the end sections of the locking recess on the support member (see FIG. 1).
  • the locking surfaces 18, 19 of the lever 13 are curved about the axis 17 and end on the trigger side with sharp edges.
  • the adjoining end part 24 or 25 is concavely curved and serves as a restoring surface for the arm 11 or 12 of the respective side jaw 7 or 8.
  • the individual parts of the front jaw normally assume their position shown in FIG. 1. If, for example, a force is transmitted to the side jaw 8 that exceeds the pretension of the helical compression spring 16, the four-bar linkage is pivoted to the right in relation to the illustration. During this pivoting, the side jaws 7, 8 do not move relative to the coupling 6 serving as a support member, since the lever 13 prevents this. When the force decreases, the detent roller 15 which has run onto the flank of the detent trough 14 returns the four-bar link to the starting position.
  • the quadrangle With the release of the shoe and the relief of the side cheek, the quadrangle resets under the influence of the locking roller 15. Shortly before reaching its normal position, the detent roller 15 runs against the part of the lever 13 protruding with respect to the detent trough 14 and pivots it in a clockwise direction with respect to the illustration (see FIG. 4). The front part 25 of the lever causes the side jaw 8 to pivot back about its pivot pin 10 until the normal position according to FIG. 1 is finally reached again.
