Definitions

  • the present invention relates to a touring binding comprising two arranged on different sides of a longitudinal axis bearing portions which are adapted to take in a walking position of the touring binding opposite lateral abutment portions of a shoe to the shoe about a transversely to the longitudinal axis extending transverse axis pivoting on the Keep touring binding.
  • Touring bindings of this type are particularly attached to touring skis and used together with an heel box, so that the touring can be adjusted in a walking position for ascent, in which the heel machine releases the heel of the shoe and the shoe can swing freely around the bearing sections, and at a Downhill the touring binding can be set in a downhill position, in which the heel counter holds the heel of the shoe securely on the ski.
  • the touring bindings discussed within the scope of this disclosure may equally be used with splitboards (longitudinally divisible snowboards, the halves of which may be used for ascent during touring) or even snowshoes.
  • An example of a known from the prior art touring binding of the type mentioned is in the EP 0 199 098 A2 discloses and includes two lateral, inwardly facing pins as bearing portions which engage in corresponding side holes of a front portion of a touring ski boot.
  • the pins are attached to distal ends of respective clamping brackets, the clamping brackets being pivotally supported on the touring binding for opening and closing the touring binding and being movable between the open position and the closed position by means of a binding actuation arrangement.
  • the ski boot When boarding in the well-known Touring binding, the ski boot must be positioned so that its lateral bearing holes are just opposite the bearing pins of the touring binding, so that when closing the binding, the bearing pins can snap into the bearing openings.
  • the correct positioning of the ski boot can often be difficult in practical use on the mountain, especially for inexperienced users.

  • the boarding aid With this boarding aid the entry into the touring binding can be significantly facilitated, however, the reliability of the correct positioning of the ski boot is limited by the boarding aid in that too much cantilevered design of the boarding aid on the ski shoe affects the usability of the ski boot when moving without skis. If, in particular, rocky subsections need to be overcome without skis, pronounced access aids to the lateral bearing openings can harbor the risk that the user will get stuck with the ski boot on a rock ledge.
  • Known touring bindings can be placed after boarding and closing the binding either in a walking position, in which a heel machine releases the heel of the shoe, so that the shoe is pivotable about the transverse axis, or can be set in a down position, in which the automatic heel Keep the heel of the shoe fixed, so that the shoe is kept fixed overall near the surface of the ski.

  • a locking device not only draws the disadvantage of additional design effort and increased weight, but can often not ensure reliable locking with sufficient security.
  • special operating effort for locking and unlocking is necessary.
  • WO 2009 12 11 87 A1 discloses a touring binding with longitudinal positioning portion which lowers in walking position down.
  • a touring binding which has improved functionality and operability to avoid the above-mentioned disadvantages of the prior art, and which in particular facilitates the correct positioning of the shoe at the entrance and / or unintentional release of the bond can avoid.

  • the coupling elements 166a, 166b are coupled to the locking section 156, which pivots forward during the transition from the first closed position to the second closed position, so that the stop elements 120a, 120b are also pulled forward.
  • the second closed position can be used as walking position of the touring binding 110, in which a heel portion of the ski boot 125 is released by a heel counter, so that the touring ski boot 125 can pivot about the axis of the bearing pin 132. This pivotal movement is no longer hindered by the folded away to the front stop elements 120a, 120b in the second closed position.
  • stop elements 120a, 120b in the second closed position can take no lateral support function more, an unwanted triggering of the touring binding 110 can be prevented in the second closed position in the manner already described with respect to the first embodiment, characterized in that between the pivot axis 148th and cam surface 158 pushed locking portion 156 blocks pivoting of the actuating lever 136 in the open position.
  • the rear abutment surfaces 62 and 162a, 162b have been formed on the same stopper member 20 and 120a, 120b, respectively, as adjacent surfaces.

  • each of the stop members 220a, 220b is disposed in a corresponding recess 217 of the associated clamping bracket 216.
  • the recess 216 may be a through opening in the clamping angle 216 through which the stop element 220a, 220b passes.
  • the stop elements 220a, 220b can thus be arranged almost in the same place as the pivotable clamping angle 216, without hindering the pivoting movement of the clamping bracket 216.
  • the stop members are formed as from the base plate 212 of integrally upwardly projecting columns or pins that pass through the through holes 217 in the clamping brackets 216.
  • a touring ski boot each facing contact surface 221 a of the left stop element 220a and a touring ski shoe facing abutment surface 221 b of the right stop element 220b do not follow exactly the contour of the corresponding sole portion of a arranged in the correct driving position Tourenskischuhs, but each have chamfers.
  • the chamfered contact surfaces 221 a, 221 b correspond approximately to the contour of a sole portion of a touring ski shoe, which is pivoted to the corresponding stop member 220a and 220b out so that the heel of the ski boot is triggered from the heel unit.
  • the tapered abutment surfaces 221 a, 221 b thus allow triggering of the heel portion of the shoe, but at the same time reliably prevent a triggering of the front portion of the shoe out of engagement with the bearing pin 232.
  • a triggering behavior and in particular a particularly high release threshold can be conveniently controlled by providing a corresponding heel counter and corresponding adjustment of the heel unit and the tripping behavior of the touring binding is not limited by the design limited triggering behavior of the terminal angle.
  • the aspect of the lateral support of the ski boot can be realized independently of the positioning of the ski boot in the X direction, this does not exclude that, for example, the stop elements 220a, 220b described in the further example can also take over a certain function of the positioning of the ski boot in the X direction.
  • the stop elements 220a, 220b described in the further example can also take over a certain function of the positioning of the ski boot in the X direction.
  • side support portions which come to rest in the vicinity of the bearing openings can simultaneously also act as stops for a forward shift of the ski boot in X- Serve direction and thus facilitate the correct positioning of the ski boot in ready to move position in the opening position of the touring binding.
