Definitions

  • the invention relates to a ski binding with a toe holder, which preferably defines a pivot axis for a ski boot held by the toe holder in a plan view of the ski binding transversely to a longitudinal direction of the ski binding, and a heel holder with a heel holder housing and a first holding element and a second holding element for a holding engagement with a ski boot heel.
  • the first holding element and the second holding element can be pivoted out of the holding engagement about a respective pivot axis, the position of which can be adjusted relative to the corresponding holding elements.
  • the position of the pivot axes relative to the holding elements determines a release force required to release the holding engagement.
  • the invention relates to a ski binding with a toe holder, which, in a plan view of the ski binding, defines a pivot axis for a ski boot held by the toe holder transversely to a longitudinal direction of the ski binding, and a heel holder.
  • the ski binding is preferably a ski binding that can be used by the user for touring.
  • the touring binding can be adjusted so that an ascent with the binding is possible, so that the ski boot is released from the heel holder, and a descent is possible with the binding, during which the ski boot is held in the heel holder.
  • the heel holder can be connected to the ski body or to a plate that can be moved relative to the ski body.
  • the toe holder is a toe holder known in the prior art, e.g. a toe holder for a touring ski binding with two so-called pins, which can engage laterally in the ski boot sole in corresponding receptacles in order to hold the ski boot in the toe holder when climbing, so that the ski boot rotates around an axis , which runs through the pins and the receptacles of the ski boot sole, can be pivoted.
  • the weight of the touring ski binding is playing an increasingly important role, especially for touring skiers, as every gram of weight saved makes touring easier.
  • you still don't want to compromise on security which is why it is essential to be able to adjust the trigger value (so-called “Z value”) when binding.
  • Z value the trigger value
  • Many models on the market only allow the Z value for horizontal release to be adjusted, whereas the Z value for vertical release is more or less fixed.
  • the ability to adjust the vertical trigger value is increasingly required. It is therefore an object of the invention to provide a heel holder for a touring ski binding which has a low weight and at the same time enables the horizontal and vertical release value to be adjusted.
  • the heel holder comprises a base, a heel holder housing projecting from the base, a first holding element and a second holding element, each of which has an engagement section for a holding engagement with a ski boot heel, a bearing section and a coupling section in the longitudinal direction between the engagement section and the bearing section.
  • the first holding element and the second holding element can be two separate components that are not formed or connected to one another.

  • the adjusting structure can be adjusted into different adjusting positions relative to the heel holder housing and the holding elements and can be fixed in each of the adjusting positions.

  • the combination of holding elements 4, 5, support devices 6, 7 with pretensioning device 10, and adjusting structure 8 can be referred to as mechanics 20 , with which a position of the pivot axes B 4 , B 5 is determined and thereby the force with which the holding elements 4 , 5 hold a ski boot heel in the holding grip can be adjusted.
  • FIG. 7 is described in detail, which is to Figure 7 What has been said applies accordingly to the Figure 8 .
  • the base 2 is shown, parts of the second heel holder housing part 33, the trigger device for a transverse release of the heel holder with the spring element 16 for adjusting the release force, and the rail S, which can be connected to a ski by means of screws.
  • the holding element 4 is also shown, which is anchored in the bearing section 43 in the support device 6, so that it cannot be moved in the longitudinal direction relative to the support device 6, but can optionally be rotated about its axis of rotation relative to the support device 6.
  • the holding element 4 is a rod, preferably made of a solid material, for example made of a light metal such as hardened aluminum or steel.
  • the holding element 4 can be a round rod, with a round, preferably circular diameter.
  • the support device 6 shown has a through opening 61 through which the bearing section 43 of the holding element 4 passes.
  • the holding element 4 in the engagement section 41 and coupling section 42 has a first diameter
  • the bearing section 43 has a second diameter which essentially corresponds to the inner diameter of the through opening 61, the second diameter being smaller than the first diameter.
  • the transition from the first diameter to the second diameter is stepped, preferably with a single step.
  • the free end of the bearing section 43 is connected to a cap 18, the diameter of which is larger than the diameter of the bearing section 43.
  • the cap 18 can be screwed onto the holding element 4 or screwed into the holding element 4 and thereby move the support device 6 in the direction of the coupling section 42 tension so that it rests firmly on the step in which the second diameter merges into the first diameter. If, as shown, the bearing section 43 passes through the support device 6 and protrudes from the support device 6 at the end facing away from the engagement section 41, the securing can also take place, for example, by a snap ring, which is preferably shaped so that it holds the support device 6 in the direction of the Coupling section 42 tensions. A relative movement of the support device 6 to the holding element 4 should be prevented by the cap 18 or the snap ring.
  • an inner peripheral wall of the through-opening 61 and/or the outer surface of the bearing portion 43 may be machined, for example finely ground or coated.
  • the support device 6 can be an abutment element 12 (see Figure 6 ), which defines a pivot axis B 4 for the holding element 4.
  • connection between the support device 6 and the holding element 4 includes a pivot bearing 19, in the exemplary embodiment a ball or barrel bearing, in order to keep frictional resistance low when the holding element 4 rotates about its rotation in the through opening 61.
  • the support device 6 of Figure 8 does not include an abutment element 12.
  • the pivot axis B 4 is formed by the edge of the end of the support device 6 facing the engagement section 41 of the holding element 4. This means that the support device 6 must be formed from a material with a material hardness that at least corresponds to the material hardness of the material from which the holding element 4 is formed.
  • FIG. 9 a further embodiment of the mechanism 20' is shown, with which the force of the holding grip of the holding elements 4', 5' of the heel holder 1 can be adjusted.
  • the exploded sketch shows that the mechanism 20' differs significantly from the mechanism 20 of the previously described version.
  • the first holding element 4' and the second holding element 5' are hook-shaped, the pretensioning device 10 transmits the pretensioning force F via a force transmission element 10a' to the support devices 6', 7' and the adjusting device 8' includes a guide 81' for the first holding element 4'. and a guide 82' for the second holding element 5'.
  • the pretensioning force F of the pretensioning device 10 acts in the Y direction.
  • the holding elements 4', 5' can be inserted and snapped into openings of the support devices 6', 7' with the hook-shaped ends 17', so that the support devices 6', 7' are no longer linear relative to the holding elements 4', 5' can move in the longitudinal direction X.
  • a rotation or pivoting of the holding elements 4 ', 5' in pivot axes formed by the rotation axes of the ends 17' is preferably possible.
  • the actuating structure 8' consists of several parts that can be coupled to one another.
  • One part is a traverse which spans the two holding elements 4', 5' in the Z direction and at the respective end comprises an arm which projects vertically in the Y direction and which laterally covers the holding elements 4', 5'.
  • Guide elements 81', 82' can be coupled to the arms, which have a through opening in the longitudinal direction X, which serve as guides for the holding elements 4', 5'.
  • the arms preferably cover the guide elements 81', 82' in the X and Y directions.
  • the guide elements 81 ', 82' have protrusions on one upper side in the Y direction Connecting elements that interact with corresponding counter-connecting elements on the traverse to establish the coupling.
  • the connecting elements are cylindrical in shape
  • the counter-connecting elements are openings in the crossbar that accommodate the connecting elements.
  • the connecting elements and thus the guide elements 81 ', 82' can preferably be pivoted in the openings about a pivot axis aligned in the Y direction.
  • the guide elements 81', 82' can have a spherical surface facing the respective arm.
  • the pretensioning device 10 is installed in the heel holder 1 in such a way that the pretensioning force F acts perpendicular to the longitudinal axis in the Y direction.
  • the prestressing device 10 acts on a force transmission element 10a', which transmits the prestressing force F to the support devices 6', 7'.
  • the force transmission element 10a' is partially truncated pyramid-shaped with two support surfaces for the support devices 6', 7'. The ends of the support devices 6', 7' facing the force transmission element 10a' have at least one oblique side or are triangular.
  • the sloping side or a leg of the triangle facing the force transmission element 10a' are designed so that they fully rest on contact surfaces of the force transmission element 10a' when the pretensioning device 10 tensions the transmission element 10a' against the support devices 6', 7'.
  • the mechanism 20' also includes the adjusting element 9, which in the example is formed from a screw 9a and a nut 9b which can be connected to the adjusting structure 8'.
  • the Figure 9 further shows the mechanics 20' after assembly.
  • the Figure 10 shows four sketches of views of and sections through the assembled mechanism 20' of the Figure 9 .
  • the first sketch a) shows a side view of the mechanism 20 'in the longitudinal direction.
  • the holding element 5' extends through the adjusting device 8' and is mounted with its hook-shaped end 17' in the support device 7'.
  • the hook-shaped end 17' of the holding element 5' extends to an opening in an upper side of the support device 7' and is essentially flat with the upper side.
  • the pretensioning device 10 presses the force transmission element 10a 'in the Y direction against the support devices 6', 7' with the pretensioning force F.
  • the second sketch b) shows a horizontal section in the longitudinal direction of the mechanism 20' at the level of the central or rotation axes of the holding elements 4', 5'.
  • This view clearly shows the spherical surfaces of the guide elements 81', 82' for the holding elements 4', 5' facing the arms of the adjusting structure 8'.
  • the spherical surfaces define the position of the pivot axes B 4 , B 5 for the holding elements 4'5'. If the ends of the holding elements 4', 5' facing away from the support devices 6', 7' are moved in the direction of the arrow, the holding elements 4', 5' pivot in the pivot axes B 4 , B 5 . As a result, the support devices 6 ', 7' are moved towards each other in the direction of the arrow and against the pretensioning force F of the pretensioning device 10 along the force transmission element 10a' in the Y direction.
  • the third sketch c) shows a vertical sectional view of the mechanism 20', in which the support devices 6', 7' are cut in the middle in the longitudinal direction X.
  • the pretensioning device 10 tensions the force transmission element 10a' in the partially pyramid-shaped area against the support devices 6', 7', which in the exemplary embodiment has a triangularly shaped end facing the force transmission element 10a'.
  • the hook-shaped ends 17' of the holding elements 4', 5' lie in a vertical bore of the support devices 6', 7' and thereby prevent the holding elements 4', 5' from moving linearly in or against the longitudinal direction relative to the support devices 6', 7' X can move.
  • the support devices 6 ', 7' are in turn installed in the heel holder housing 3, not shown, so that they cannot move linearly in or against the longitudinal direction X relative to the heel holder housing 3.
  • the fourth sketch d) shows a vertical section through the middle of the adjusting structure 8' with the guide elements 81', 82'.
  • the guide elements 81 ', 82' are with the Traverse of the adjusting structure 8 'coupled or connected as shown, the guide elements 81', 82' lie in the area of a respective apex or a respective apex line of the spherical tops on the inner walls of the arms of the adjusting structure 8' facing the guide elements 81', 82'.
