Definitions

  • the present invention relates to a braking arrangement for a touring binding, the braking arrangement being adjustable between a braking position and a sliding position, comprising a base with an attachment arrangement for attachment to a ski and/or to the touring binding, a pedal which is on its side facing away from the ski has a tread for a shoe, in particular for a heel section of a ski boot, at least one brake arm which is mounted on the base and on the pedal, at least a first elastic element which is designed to prestress the brake arrangement in the braking position, a locking element and a blocking element.
  • the present invention relates to a heel unit comprising such a braking arrangement.
  • a braking arrangement for touring bindings is intended to brake the ski in the event that a ski boot and a touring binding become uncoupled, for example if a user falls, also called release, or otherwise loses a ski on sloping terrain, in order on the one hand to prevent a complete loss of the ski and on the other hand a To prevent endangerment of other winter sports enthusiasts as a result of a ski loss.
  • a brake arrangement for touring bindings represents an important safety aspect.
  • a sole section of the ski boot conventionally presses a pedal down against the force of an elastic element and at least one brake arm connected to the pedal, in particular two brake arms, is Raised in relation to a ski plane in the vertical direction to a level above a ski running surface, so that the brake assembly is in a sliding position and the brake arm or arms for climbing up or down with the skis can no longer engage with the ground and brake the skis.
  • a touring binding in addition to skiing downhill, you can also climb up by attaching so-called climbing skins to the ski surface.
  • a touring binding conventionally includes a heel unit that is coupleable to a heel portion of a ski boot and a front unit that is coupleable to a toe portion of a ski boot.
  • both the heel section is coupled to the heel unit and the toe section is coupled to the front unit.
  • both the toe section is pivotally coupled to the front unit, so that a ski boot heel can be lifted off the heel unit, or the heel unit and the front unit are coupled together, both remain on the ski boot and comprise a hinge on the front unit, which allows lifting of the Ski boot allowed by the ski together with the heel unit. In the latter case, the heel unit and front unit assembly can be locked onto the ski for skiing.
  • touring bindings can also be used for ascent, it is necessary to lock or block the brake assembly in the sliding position, in which the brake arm or arms are raised to a level above the ski surface even without the ski boot exerting force on the pedal, since when ascending a Ski boot heel is raised and the sole portion of the ski boot no longer presses the pedal down.
  • the heel of the ski boot can be raised from the brake assembly for climbing, without the or the Brake arms can engage with the ground and brake the ski.
  • low weight and a slightly complex structure play an important role in touring bindings and also brake arrangements for touring bindings.
  • a simple structure is an advantage, since the binding systems should work absolutely reliably even under the influence of ice and snow.
  • a brake arrangement is an important safety aspect for touring bindings.
  • the blocking element can be unlocked without having to first release the pedal by hand must be pressed down, can first be placed in the blocking position and then by lowering the ski boot and depressing the pedal with the ski boot, the brake assembly can be brought into the sliding position and locked there.
  • Another safety aspect is to prevent incorrect operation of the brake assembly through the structure and design of the touring binding and/or the brake assembly.
  • the following process is referred to as incorrect operation: It can happen that a user adjusts the brake arrangement into the sliding position and locks it in the sliding position by means of the blocking element. If he now couples the toe section and the heel section of his ski boot with a touring binding for downhill skiing, the touring binding is in a downhill configuration, but the brake arrangement is not in the braking position necessary for the downhill configuration.
  • a brake assembly or a heel unit which includes a brake assembly, with easier operability and thus better user comfort, which in particular has improved brake locking function and / or which provides a function that prevents incorrect operation.

  • Important features of the invention are thus the adjustability of the blocking element between the blocking position and the release position and, in particular, the prestressing of the locking element into the engaged position.
  • This bias makes it possible that, when the blocking element is placed in the blocking position, the locking element remains securely in the engaged position and the brake assembly is reliably locked in the sliding position and also automatically into the engaged position after it has been moved returns.
  • This arrangement advantageously enables a step-in function. If the blocking element is placed in the release position, the locking element does not engage with the blocking element at all and the brake assembly remains unlocked and biased into the braking position, so that it can brake the ski safely in the event of a fall or the like.

All of these objects or parts thereof are regarded as skis or parts of skis within the meaning of this invention.
  • the blocking element can be set up to block the brake assembly in the sliding position in its blocking position. This can be done in particular by an interaction of the blocking element in the blocking position and the locking element in the engaged position, whereby a particularly reliable brake lock can be provided in a simple manner.
  • the blocking element can be mounted on the brake assembly, in particular on the base, such that it can rotate about an axis of rotation that is essentially perpendicular to a plane of the ski, such that when it is adjusted between the blocking position and the release position, it moves in a plane that is essentially parallel to a plane of the ski.

If the locking element is provided on a pedal underside, it does not protrude from the brake assembly. In this way, on the one hand, a compact, space-saving arrangement can be achieved and, on the other hand, the locking element can be prevented from being displaced by external influences or being released from the engaged position, which can happen with conventional brake arrangements, for example, if the user's ski boots and so that parts of a left and a right touring binding may collide.
  • the locking element can be provided in the form of a hook, the hook being adapted to engage a contour of the blocking element in the engaged position of the locking element when the blocking element is in the blocking position is.

  • This common stop can prevent the blocking element 70 from being displaced into the blocking position when the heel unit 100 is placed in the driving position and the lip 132 and the contact section 138 of the binding body 130 point forwards in the direction of travel. Conversely, when the heel unit 100 is in the walking position, the abutment portion 78 on the extension 78 of the blocking element 70 is spaced from the binding body 130 because the portion where the lip 132 is provided is rotated away, and the blocking element 70 can be moved to the blocking position will.
