Definitions

  • the invention relates to a ski binding for a cross-country or touring ski, with a holding shell resting on the sole edge of the shoe at the top and bottom, which is spring-loaded in the open position in the sense of pivoting upward about a transverse horizontal axis lying in front of the shoe runs diagonally upwards and can be brought down into a closed position by means of pivoting of the shoe, in which at least one locking pin penetrates an opening in the shoe from below and a pawl arranged on the same, optionally pivotable, part of the binding as the locking pin on the holding shell is engaged.
  • Such a device has become known, for example from AT-PS 386 127, which has already proven itself in practice. Nevertheless, the invention has set itself the goal of improving the known device. This improvement is intended to prevent the pawl which is used to lock the shoe in the binding from projecting relatively far upward beyond the general profile of the binding and thereby being at increased risk of wear.
  • This task is also based on the device according to DE-OS 34 05 861. In this case, however, a hold-down corresponding to the holding shell and a holding part corresponding to the pawl, which cooperate in the manner of a locking mechanism, lie one behind the other in the longitudinal direction of the ski, as a result of which the binding as a whole is relatively long. According to the invention, however, a compact construction of the binding in the longitudinal and vertical directions is to be achieved.
  • the object is achieved in that the axis, about which the pawl is pivotable, lies behind the axis of the holding shell, and that the pawl passes through the holding shell from below when the binding is closed and rests on the upper side thereof.
  • the pawl only protrudes upwards beyond the holding shell even when the binding is closed, so that the binding can be opened by inserting a ski pole into the pawl.
  • both the pawl and the locking pin are on a ski-fixed bearing body, namely on the base plate of the binding.
  • the inventive laying of the pawl axis down has the particular advantage that no additional pivot axis has to be introduced if you want to make the locking pin pivotable independently of the pawl.
  • Such swiveling is extremely welcome, as it allows the shoe to be easily threaded in and out when the locking pin is inclined and to secure the shoe inserted into the binding by twisting the locking pin.
  • the pivoting of the locking pin into the closed position can be positively controlled by arranging the locking pin on a double lever, the end of which is opposite the locking pin and is guided through the inside of the holding shell when the binding is closed.
  • the pivoting of the Locking pin when opening the binding is carried out by a leg spring arranged on the pivot axis of the locking pin.
  • the described pivoting of the locking pin would also be possible and sensible with an arrangement of the pawl according to AT-PS 386 127.
  • the disadvantage was occasionally observed that icing is sometimes present in the very last part of the closing path of the holding shell, so that it is only possible to push the ski boot completely onto the locking pin after removing the obstacle or with considerable effort .
  • the functionality of the binding is ensured irrespective of whether the holding shell can really be pressed down completely. This is achieved in that the contact point of the pawl on a transverse web of the holding shell is designed as a double catch, which allows the fixing of two angular positions of the holding shell relative to the part of the binding which carries the pawl and the locking pin (s).
  • FIG. 1 is a section through a first exemplary embodiment along a vertical longitudinal axis
  • FIG. 2 is a partially sectioned top view
  • FIG. 3 is a section along line III-III in FIG. 2
  • FIG. 4 is a representation of the individual components of the device according to FIG 1 to 3
  • FIG. 5 the side view of the front part of a shoe
  • FIGS. 6 to 9 show a second embodiment in a representation analogous to FIGS. 1 to 4
  • FIG. 10 shows a third embodiment.
  • the binding shown comprises a bearing body 1 which is fixedly connected to a ski 14.
  • a holding shell 2 is pivotally mounted about an axis 5.
  • a leg spring 17 tries to pivot the holding shell 2 relative to a swivel part 15 consisting of two interconnected arms. This is only possible if the pawl 4, which is pivotably mounted on the pivoting part 15 about an axis 6, is removed from the double catch 4b by pivoting counterclockwise.
  • the position of the binding shown in FIG. 1, on the other hand corresponds to the closed position, in which a locking pin 3 penetrates the opening between a transverse web 12 and the end face 13 of the shoe shown in FIG. 5. In this position, a movement of the holding shell 2 and of the locking pin 3 mounted on the swivel part 15 is only possible together against the action of a compression spring 16 made of rubber or plastic.
  • the swivel part 15 In the ready position of the binding, not shown in FIG. 1, the swivel part 15 is in its deepest position, the holding shell 2 in its highest position.
  • the locking pin 3 is removed from the holding shell 2 and points obliquely to the shoe. After inserting the shoe into the holding shell and pressing it down, the locking pin 3 is pivoted counterclockwise, pulling the shoe fully into the binding. This pivoting takes place through the interaction of the control surfaces 9 with the guide surfaces 7 on the holding part 2.
  • the transverse web 2a of the holding shell 2 simultaneously slides over the curved upper side of the pawl 4 and pivots the pawl 4 counterclockwise until it slides past the front of the transverse web 2a .
  • the pawl 4 engages for the first time in the double catch 4b.
  • the binding can already be used, especially since experience has shown that it only takes a short time for the double latch shown to move from the provisional position, which is only shown in connection with the second exemplary embodiment in FIG. 6, to the final position according to FIG. 1 .
  • the device according to FIGS. 6 to 9 differs from that according to FIGS. 1 to 5 in that here the joint pivoting of the holding shell 2 and the locking pin 3 against the action of a compression spring is dispensed with. Both the pawl 4 and the pivotably mounted locking pin 2 are therefore attached to the bearing body 1 here, so that the closed binding cannot be moved relative to this bearing body 1. It would be conceivable for the axis 6 or the like in a slot arranged in the vertical direction by means of a rubber buffer or the like. elastic to store and thereby allow a limited height movement of the part of the shoe clamped in the binding. Such a height movement can be particularly desirable in skating technology.
  • the binding according to FIGS. 6 to 9 in the illustration according to FIG. 6 is in the state in which the double catch 4b already fixes the holding shell 2, but the locking pin 3 is not yet completely in the opening between the crosspiece 12 and end face 13 has penetrated the shoe 10.
  • the pawl 4 moves into a position as shown in FIG. 1 in connection with the first exemplary embodiment.
  • the pawl 4 shows the possibility of providing the pivotable arrangement of the locking pin 3 even when the pawl 4 is mounted above the holding shell 2 in a manner known per se.
  • the need to provide a separate axis 20 for the pawl 4 means that the lower pawl bearing according to the two preceding exemplary embodiments is generally preferred if the locking pin 3 is to be arranged pivotably.
