Definitions

  • the invention relates to heel machines for a ski binding, in particular a touring ski binding, with a base element for mounting the heel unit on the top of a ski and a carriage mounted on the base element, on which a heel holder with at least one holding means for holding a ski boot in a heel region of the ski boot is arranged ,
  • These automatic heel units have a downhill position in which the at least one holding means can interact with the heel region of the ski boot held in the ski binding in such a way that the ski boot is locked in a lowered position.
  • these automatic heel units have at least one climbing position, in which the heel area of the ski boot held in the ski binding is released.
  • ski bindings are subdivided into piste bindings, which are used only for downhill skiing and downhill skiing, and touring bindings, which are also used for walking on skis, in particular for ascending with the help of climbing skins attached to the skis. While the former only have to ensure a reliable fixation of the ski boot on the ski in a so-called downhill position, the latter must be brought to ascend additionally from the downhill to a climbing position in which the ski boot is pivotable about an axis in Skiquerides pivotally in the heel area of the ski to allow for joint movement between the ski boot and the ski to go.
  • Touring ski bindings can be divided into two types.
  • One type comprises a ski boot carrier which can be pivoted relative to the ski and to which the ski boot is held by binding jaws.
  • a representative member of this type of touring ski bindings is described, for example, in EP 0 754 079 B1 (Fritschi AG).
  • the second type relies on ski boots with stiff soles.
  • the ski boot is pivotally mounted in his toe area in a skim-mounted front automat.
  • the automatic heel unit is also fixed in a distance from the front automat on the ski adapted to a ski boot sole length and locks the ski boot in the heel area in the downhill position.
  • ski boots In the ascent position, the heel of the ski boot is released from the heel unit, so that the ski boot can be lifted off the ski and swiveled around the storage on the front automat.
  • this type of binding suitable ski boots this typically have in the toe area two lateral recesses for pivotal mounting in the front vending machine. Next, they have in the heel area to the rear open recesses into which holding means of the heel unit can intervene.
  • the distance in which the heel counter must be mounted on the ski from the front automatic is dictated by the length of the sole of the ski boot to be held within the scope of adjustability of the heel piece.
  • the mentioned ascent position, in which the heel of the Ski boot is released thus always refers to the downhill position, in which the heel of the ski boot can be locked at the same mounting position of the heel unit.
  • ski longitudinal direction means along the orientation of the longitudinal axis of the ski.
  • skiparallel means aligned for an elongated object along the longitudinal axis of the ski.
  • ski-parallel means parallel to the sliding surface of the ski.
  • ski direction means a direction transverse to the ski longitudinal direction, which, however, need not be oriented exactly at right angles to the longitudinal axis of the ski. Their orientation may also be slightly different from a right angle.
  • ski center means a center of the ski in the ski direction
  • ski manifest does not mean that it can move in relation to the ski.
  • terms that do not contain the word “ski” also refer to the reference system of the (fictional) ski, for example, the terms “front”, “rear”, “top”, “bottom” and Similarly, terms such as “horizontal” and “vertical” refer to the ski, with “horizontal” in a ski-parallel Plane lying and “vertical” aligned perpendicular to this plane means.
  • a touring ski binding of the second type introduced above is described in EP 0 199 098 A2 (Barthel) and sold under the name Dynafit.
  • An automatic front-end system of this system has two tensioning parts, each with a journal oriented in the direction of the ski, which engage in recesses in the toe area of the ski boot when entering the touring ski binding from the sides.
  • the pins form a pivot bearing of the ski boot on which the ski boot can be pivoted relative to the ski.
  • a self-powered heel machine of this system has two pins located on a heel cup. In the downhill position these two pins are aligned towards the front of the machine, making them in recesses in the Engage the heel of the ski boot and thereby lock the ski boot in a lowered position towards the ski.
  • the ski boot is first stored in the front vending machine. Then the heel of the ski boot is lowered from above onto the pins of the heel holder. Since the recesses in the heel of the ski boot downwards are largely open, thereby the recesses are guided over the pins, whereupon the pins engage in locking recesses in the recesses for locking.
  • both pins can be pressed apart against a spring force, allowing them to slide out of the detent recesses and the recesses and release the heel of the ski boot upwards.
  • both pins are each arranged on a lever, which is mounted in a horizontal plane pivotally mounted on the heel holder. Both levers are biased by a spring force, so that the two pins are pressed towards each other.
  • the spring force By adjusting the spring force, the force can be specified, which is required to allow a trigger in the forward direction. This allows a safety release in the forward direction.
  • the toe area of the ski boot is first detached from the front automat for the intended binding exit. Then the heel of the ski boot is pulled forwards from the pins of the heel counter.
  • An automatic heel unit according to EP 0 1 9 098 A2 can be brought into a climbing position by the heel holder is rotated by the skier about a vertical axis until the two pins are pivoted to the side of the trajectory of the heel of the ski boot.
  • the heel holder has a plurality of rotational positions in which the pins are pivoted out of the path of movement of the heel. These individual rotational positions are each predetermined by a spring catch for locking the heel holder. When the heel holder is in one of these rotational positions, the trajectory of the heel of the ski boot is free and the ski boot can be lowered down to the ski.
  • the heel holder when the heel holder is in one of the other rotational positions, one is located at the heel holder Pad pivoted at a certain distance to the ski in the trajectory of the heel of the ski boot. Any such support prevents the ski boot from descending to the ski at a different distance from the ski. Accordingly, different climbing aids can be adjusted by positioning the heel holder in the different rotational positions.
  • the heel unit can not be brought directly from the downhill position in one of the ascent positions.
  • the required rotation of the heel holder about the vertical axis can only be operated when the ski boot was previously completely released from the binding. Especially in loose deep snow and on steep terrain, this can lead to tricky situations, as a ski boot, in contrast to the large surface of a ski offers the skier only little grip.
  • the automatic heel unit comprises a ski base plate and a carriage with a heel holder, wherein the carriage is displaceable by a lever relative to the base plate in the ski longitudinal direction.
  • the carriage is comprised of a multi-part housing, from which the heel holder protrudes upward through a slot adapted to the displaceability.
  • the carriage In the down position, the carriage is moved to a front position, whereby the pins can engage in the recesses in the heel of the ski boot.
  • the carriage In the ascent position, however, the carriage is moved to a rear position, whereby the pins can not engage in the recesses in the heel of the ski boot and the heel of the ski boot is released accordingly.
  • the heel piece according to WO 2009/121 187 A1 (G3 Genuine Guide Gear Inc.) comprises a plurality of support levers, which can be pivoted sequentially from back to front into the trajectory of the ski boot.
  • the automatic heel unit according to WO 2009/121 187 A1 (G3 Genuine Guide Gear Inc.) comprises a ski brake. This ski brake has two arms, which can be swung out over the ski for activation downwards. Furthermore, the ski brake has a tread spur.
  • the arms of the ski brake can be pivoted against a spring force in a substantially skiparallel alignment, whereby the ski brake is in a rest position. If in the downhill position a ski boot is locked in the heel area in the heel counter, the tread spur is pushed down through the sole of the ski boot and the ski brake is in the rest position. In the case of a skier falling, which triggers a safety release, the ski brake is automatically activated by the spring force, since the tread spur is no longer pressed downwards by the sole of the ski boot. When the heel piece is transferred to the ascent position, the heel piece is moved backward in the heel piece according to WO 2009/121 187 A1 (G3 Genuine Guide Gear Inc.).
  • a hook is released in a front region of the housing, which can hook in the tread spur and hold it in a lower position. Accordingly, the ski brake in the ascent position can be held by this hook in the rest position, without the sole of the ski boot pushes the tread spur down.
  • the heel piece according to WO 2009/121 187 A1 (G3 Genuine Guide Gear Inc.) has an improved handling compared to the heel piece according to EP 0 199 098 A2 (Barthel).

  • the ski brake 209 is thus designed as an independent part, which can be attached to the base plate 3 via the base part 250.
  • the base part 250 has guide grooves 250.1 and 250.2 (guide groove 250.2 in the sectional view of FIG. 18 is not visible), which analogously to the carriage 5, the guide rails 102.1, 102.2 of the base plate 3 include.
  • the ski brake 209 can thus be guided displaceably guided on the base plate 3 with the base part 250 in the longitudinal direction.
  • retaining cam 254.1 and 254.2 are formed (retaining cam 254.2 is not visible in the sectional view of FIG. 18), with which the base member 250 in corresponding recesses of the intermediate piece 4 (not shown) from below can be hung here. This takes place, if a ski brake 250 is even desired, before the carriage 3 and the intermediate piece 4 are pushed onto the guide rails 102.1 and 102.2 of the base plate 3 during assembly of the automatic heel unit 1. This ensures that the base part 250 of the ski brake 209 fixed with respect to a longitudinal displacement (but by Removing the carriage 3 and the intermediate piece of the base plate 3 detachably) is coupled to the intermediate piece 4.
  • the ski brake 209 is thus displaced with an adjustment of the longitudinal position with respect to the base plate 3 via the spindle drive 124 of the intermediate piece 4 described above and is thus in each longitudinal position of the intermediate piece 4 at the same desired distance to the intermediate piece 4 and thus also to the carriage 3 coupled thereto on which the sole holder 8 is mounted.
  • the foot plate 251 at a rear end face on a projection 255 which is chamfered at an underside in the rearward direction upwards.
  • the projection 255 is arranged such that the nose of the bolt 210 can be brought into engagement with the projection 255 when the bolt 210 is in the activated position and the foot plate 251 is lowered.
  • the latch 210 When the projection 255 passes under the latch 210, the latch 210 snaps forward due to the spring force, so that it overlaps with the projection 255. In the activated position, the latch 210 thus provides a snap-lock for the foot plate 151 of the ski brake 209. The activated latch 210 thus prevents the foot plate 251 from being raised again when the foot plate 251 is lowered - the ski brake 209 is thus locked in a rest position.
  • This embodiment of the latch 210 thus ensures that the foot plate 251 of the ski brake 209 can be locked without the risk of damaging the actuator, even if the latch 210 is already in the activated position when the foot plate 251 is lowered, for example, by a binding entry.
  • the invention is not limited to the first heel machine 1 shown here and the second heel machine 1 shown here. There are a variety of variations possible. As shown in FIGS. 19a and 19b, for example, an heel automat 550 according to the invention can also be brought from the downhill position into the at least one rise position such that the heel holder 552 is rotated about a substantially vertical axis, so that the holding means 553.1, 553.2 no longer engage with the Heel of the ski boot can interact.
  • the heel unit 550 can be designed, for example, as described in EP 0 199 098 A2 (Barthel).
  • the substantially vertical axis should be arranged either on the carriage or on the base element (551), so that the carriage is movable in the downhill position along the dynamic range.
  • an automatic heel is provided which increases the safety for a skier.

Abstract

L'invention concerne une talonnière (11) d'une fixation de ski, en particulier d'une fixation de ski de randonnée, comportant un élément de base (12) pour le montage de la talonnière (11) sur la face supérieure d'un ski (501) et un chariot (13) monté sur l'élément de base (12) et sur lequel est agencé un support de talon (14) comportant au moins un moyen de retenue (17.1, 17.2) qui maintient une chaussure de ski dans la partie talon de la chaussure de ski. Ladite talonnière (11) présente une position de descente dans laquelle le ou les moyens de retenue (17.1, 17.2) peuvent coopérer avec la partie talon de la chaussure de ski maintenue dans la fixation de ski, de telle manière que la chaussure de ski soit bloquée dans une position abaissée. Ladite talonnière (11) présente par ailleurs une position de montée dans laquelle la partie talon de la chaussure de ski maintenue dans la fixation de ski est dégagée. Selon l'invention, le chariot (11) peut, dans la position de descente, être déplacé avec le support de talon (14) par rapport à l'élément de base (12) le long d'une zone dynamique dans le sens de la longueur du ski.
