Definitions

  • the present invention relates to a heel unit for a ski binding, in particular a touring binding, the heel unit being adjustable between an engagement position, in which it engages a heel section of a ski boot to be coupled to the heel unit, and a release position, in which it engages the heel section of the ski boot releases, and wherein the heel unit has a base which has a fastening arrangement for fastening to a ski surface, a binding body which has engagement means for engaging the heel portion of the ski boot, the binding body for adjustment between the engagement position and the release position of the heel unit by one a ski plane defined by the ski surface, essentially orthogonal, vertical axis of rotation, is rotatably mounted on the base, and comprises an elastic element which is essentially parallel to the ski plane and orthogonal to the vertical axis of rotation se is arranged and biases the binding body into the engaged position of the heel unit.
  • Such conventional heel units for ski bindings usually have an axle body, in particular fixed to the base, in the form of a post or peg which is arranged in particular orthogonally with respect to a ski level and which provides a vertical axis of rotation and around which a binding body of the heel unit rotates about this vertical axis of rotation.
  • An elastic element which is usually in the form of a spring, in particular a compression spring, is mostly supported on one side on this axle body and on the other side on a section on the binding body.
  • a safety release can be provided by a rotation of the binding body around the axle body against the spring force of the elastic element.
  • the elastic element it is also possible for the elastic element to be accommodated in the axle body itself and, for example, to protrude through it.
  • a heel unit for a ski binding in particular a touring binding
  • the heel unit being adjustable between an engagement position in which it engages a heel section of a ski boot to be coupled to the heel unit, and a release position , in which it releases the heel portion of the ski boot
  • the heel unit has a base which has an attachment arrangement for attachment to a ski surface, a binding body which has engagement means for engaging the heel portion of the ski boot, the binding body for adjustment between the engagement position and the release position of the heel unit is mounted on the base so as to be rotatable about a vertical axis of rotation that is essentially orthogonal to a ski plane defined by the ski surface, and comprises an elastic element which is essentially parallel to the r ski plane and is arranged orthogonally to the vertical axis of rotation and biases the binding body into the engaged position of the heel unit, wherein the elastic element rotates together with the binding body about the vertical axis of rotation during the adjustment between the engaged position
  • the vertical axis of rotation is not in the form of a peg or post, but in the form of a virtual axis of rotation over which the elastic element extends.
  • weight can be saved as a result of the lack of an upright peg or post.
  • the superimposed arrangement of the vertical axis of rotation and the elastic element offers a particularly compact design, in particular in the direction of action of the elastic element, since the installation space is almost exclusively limited to the length of the elastic element.
  • top, bottom, front, “rear”, “side”, “height direction”, “width direction”, “length direction” and the like are used Simplification of the illustration refer to the view of a skier who has stepped with a ski boot into the heel unit of a ski binding, in particular touring binding, mounted on a ski, the ski being arranged in a horizontal plane.
  • ski and the terms containing this term such as “ski boot”, “ski binding”, “touring ski binding”, “ski level”, “ski longitudinal axis”, “central ski axis”, “ski width direction”, “ski longitudinal direction” and the like should not only refer to skis in the narrower sense, but also include splitboards (snowboards that can be divided into at least two parts in the longitudinal direction, the individual parts of which can be used in the manner of normal skis), snowshoes or similar boards for walking or gliding on snow and ice. All these objects or parts thereof are regarded as skis or parts of skis for the purposes of this invention.
  • the elastic element can preferably be at least one spring.
  • the use of a spring as an elastic element can advantageously lead to a compact design of the heel unit and can also offer a good ratio between small installation space and high stability of the arrangement.
  • the elastic element can preferably be a spring, in particular a compression spring, the spring axis of which intersects the vertical axis of rotation, in particular at a right angle. If the spring axis of a spring, in particular a compression spring, intersects the vertical axis of rotation, in particular halfway along the length of the spring, an extremely compact design of the heel unit can be achieved since the entire arrangement is almost exclusively limited to the length of the spring. The absence of a tenon or post results in less weight.
  • a compression spring is a particularly compact and stable type of spring that is also resistant to component failure.
  • the binding body can comprise at least two housing parts which form a receptacle for the elastic element, at least one housing part being displaceable in relation to the other housing part, in particular in a central position of the binding body in the engaged position in a longitudinal direction of the ski and a first end of the elastic element is supported directly or indirectly on a first of the two housing parts, while a second end of the elastic element opposite the first end is supported directly or indirectly on the other of the two housing parts.
  • Such an arrangement can advantageously ensure a compression of the elastic element, which is necessary for providing triggering forces.
  • Indirect support is to be understood here as meaning that the spring ends can also be supported on components that are stationary in relation to one of the two housing parts.
  • the binding body comprises at least two housing parts
  • one of the two housing parts can be guided along a link guide assigned to the base in such a way that when the binding body rotates about the vertical axis of rotation, the distance between the end of the elastic, which is supported directly or indirectly on this housing part Element for the vertical axis of rotation in a central position of the binding body in the engaged position of the heel unit is larger than in a release position of the binding body, which is a transition position between the engaged position and the released position of the heel unit.
  • Providing a link guide assigned to one of the two housing parts allows the release curve to be set, that is to say the profile curve of the forces acting when the heel unit is released or the adjustment between the engagement position and the release position. By changing the geometry of such a link guide, in particular through different steep angles of the link surface, such a release curve can be adapted as desired.
  • the heel unit can preferably further comprise a stop element which is set up to prevent the housing parts that are displaceable relative to one another from becoming detached.
  • a stop element which can be in the form of a locking pin, for example, after the heel unit has been triggered and / or the engagement between the heel unit and the heel section of the ski boot is released or the Binding body around the vertical axis of rotation beyond the release position, the mutually movable housing parts and other components of the heel unit are held together.
  • the heel unit can further comprise a centering device which is designed to pretension the binding body in the engaged position into a central position until a force acting on the engaging means of the binding body exceeds a predetermined threshold value.
  • a centering which can be provided, for example, as a projection or recess provided on the base or fixed to the base, can ensure a particularly user-friendly arrangement.
  • Such a projection or such a recess can cooperate with a complementary recess or a complementary projection in order to pretension the binding body in the engaged position in a central position or to keep it centered.
  • the binding body can be kept centered in the middle position without any great force being exerted on the engagement means of the binding body or the binding body itself, which, for example, makes it easier to get into the heel unit.
  • a pretensioning of the elastic element can preferably be adjustable by adjusting means.
  • adjusting means for example, different triggering forces can be set for users of different weights or users with differently sporty driving styles, in that the elastic element is pretensioned more strongly for higher triggering forces and less strongly for lower triggering forces.
  • Such adjustment means can be provided, for example, in the form of a simple threaded screw on which one end of the elastic element can be supported directly or indirectly.
