Definitions

  • the invention relates to a safety ski binding, in particular heel holder, according to the preamble of patent claim 1, 2 or 7.
  • Such a heel holder is described in DE-A1-32 04 468 in FIGS. 6 and 7.
  • the two-armed lever with the locking member engages in the recesses of the swivel and base plate, which are located one above the other, and locks them.
  • the lever In the down position, the lever is pivoted through the side wall of the housing against the action of a spring via an extension of the lever that protrudes laterally, thereby lifting the locking member of the lever out of the recesses, so that the swivel plate can rotate about the vertical vertical axis again .
  • the open heel holder is locked between the spring housing, which also acts as the release lever in this binding, and a locking body on the base plate, which also serves for diagonal control, the control curve for the diagonal release being located on the sole holder located.
  • the coordination between diagonal release and diagonal locking is somewhat unfavorable with this version, since the only locking body on the base plate is responsible for both functions. Furthermore, this type of diagonal release and locking is linked to the use of this particular type of binding.
  • AT-A2-376.374 describes a heel holder that can be moved on a ski-fixed guide rail against the force of a thrust spring during boarding by means of a ski shoe, the thrust spring being supported at one end on the base plate and at the other end on an adjustment catch which is used for longitudinal adjustment of the Binding can be locked with the ski-fixed guide rail.
  • the adjustment catch carries a locking element which, in each binding position in which the thrust spring has a lower tension than in the driving position, locks the bearing block and thus the sole holder against lateral rotation, in this position of the heel holder a locking element between two extensions of the bearing block or sole holder intervenes.
  • the bearing block Since the locking element of the adjustment catch is located in the rear area of the heel holder, where the vertically standing pivot axis of the bearing block is located, the bearing block is locked in the vicinity of the pivot point, which, as has already been stated, is unfavorable.
  • a heel holder is described in the exemplary embodiment according to FIGS. 1 to 6, in which the locking of the open heel holder between an effective heel member Locking arm and the base plate.
  • the locking rocker also takes on the function of a locking lever, since when the binding is open, the spring housing is pivoted back into the starting position with the release spring due to a centering spring, the locking rocker also being pressed into its starting position with locking on the control curve of the base plate.
  • the heel holder is open, it cannot be pivoted in the horizontal plane.
  • this double function of the locking arm is a prerequisite for integrating the function of the locking lever in the locking arm.
  • the object of the invention is to create a heel holder of the type mentioned at the outset which enables the ski boot to be centered without difficulty even when climbing into the binding, without having the disadvantages of the solutions mentioned above.
  • the measures according to the invention ensure that the bearing block is in its central position and cannot swing out about its vertical axis. Since the lock is not effective when the heel holder is closed and the ski boot is inserted in the binding, diagonal release in this state is possible at any time.
  • the fact that the locking takes place in a region distant from the pivot point of the swivel plate results in favorable force ratios. Due to the operative connection of the locking lever with the sole holder, the locking member engages in such a way that when the Heel holder, the swivel plate is only locked after the sole holder has been released by the locking rocker, ie after the trigger point has been exceeded.
  • a structurally simple construction of the diagonal lock is obtained according to claim 1 in that the locking member is an extension of the release lever designed as a locking lever.
  • the symmetrical structure is also used favorably with respect to the diagonal lock.
  • the spring that acts on the locking lever is, according to claim 6, a spiral compression spring that is easy to install and easily replaceable if necessary.
  • the features in claim 8 determine the shape of the control cam, which consists of various arcuate sections that correspond to the elastic range of the heel holder, the unobstructed opening and the diagonal pivoting of the heel holder.
  • intersection of the control curve between the sections which correspond on the one hand to the elastic range and on the other hand to the unimpeded opening of the heel holder, is determined according to claim 9 by the trigger point of the heel holder.
  • leg spring By using a leg spring according to claim 10, its legs can be supported in a simple manner on the arm of the locking lever provided with the control cam or on the swivel plate.
  • a heel holder designated in its entirety with 1 can be seen.
  • the heel holder 1 has a guide rail 3 fastened on the top of a ski 2 by means of (not shown) screws, on which a base plate 4 of the heel holder 1 is slidably guided in the longitudinal direction of the ski 2 and in a manner known per se for adapting the binding to different long ski boots can be locked in the desired position.
  • the heel holder 1 is displaceably guided against the force of at least one (not shown) thrust spring on the guide rail 3, the thrust spring being ski-like on one side and supported on the other side on the base plate 4 of the heel holder 1 in a manner known per se.
  • a rivet designed as a pivot 5 riveted, about which a pivot plate 7 is pivotally mounted in the horizontal plane, preferably against the force of a return spring 6.
