Definitions

  • the present invention relates to a heel unit for a gliding board binding, in particular for a touring binding, comprising a base with a fastening arrangement for attachment to a gliding board, a binding body which is rotatable relative to the base about a release axis of rotation running orthogonally to a gliding board plane, coupling means arranged on the binding body, which are designed to be in engagement with a heel section of a gliding board shoe in a downhill position of the gliding board binding in order to hold the gliding board shoe on the gliding board binding, the coupling means protruding from the binding body in the downhill position in a longitudinal direction of the gliding board, in particular in a forward direction of travel, and an Mz release mechanism, which is set up to bias the coupling means into the departure position in such a way that they release themselves from engagement with the gliding board shoe in the departure position upon the action of a force exceeding a predetermined release force and are released
  • heel units discussed in the present disclosure are in particular heel units for touring bindings that are to be mounted on skis or touring skis.
  • split boards are equally suitable as sliding boards to which a heel unit according to the present invention is to be attached (snowboards that can be divided in the longitudinal direction, the halves of which can be used like touring skis) or similar, so that the invention also relates to heel units for bindings of such sliding boards, although reference will be made below mainly to touring bindings without limiting the subject matter of the invention.
  • Heel units of this type are, for example, from the DE 10 2011 079 210 A1 or even that one EP 0 199 098 A3 known and usually have a base-fixed axle body in the form of a post or pin arranged essentially orthogonally with respect to the sliding board plane, around which the binding body can rotate.
  • a spring means is provided in the form of a compression spring, which is supported on one spring end section on a link surface provided on this axle body and on the other spring end section on a section on the binding body in order to bias the heel unit into the departure position.
  • This configuration provides an Mz safety release in the event of a fall by a user of the heel unit when forces occur on the coupling means that exceed a predetermined threshold value by rotating the binding body around the axle body against the spring force of the compression spring.
  • Mz and My are release torques of sliding board bindings.
  • My is the torque for a trip when a torque is applied about a sliding board transverse axis (Y-axis) if this torque exceeds a My trip torque.
  • Mz is the torque for release upon rotation of the gliding board shoe in the gliding board binding and My is the torque upon a forward tilt, for example a forward fall. Accordingly, an Mz safety release ensures that the sliding board shoe is released from the sliding board binding upon the action of a torque about a Z-axis if this torque exceeds an Mz release torque.
  • the Z-axis runs parallel to the release rotation axis which is orthogonal to the gliding board plane.
  • the Mz trigger mechanism is for this intended to provide such an Mz safety release in the most defined manner possible.
  • a heel unit for a gliding board binding in particular for a touring binding, comprising a base with a fastening arrangement for attachment to a gliding board, a binding body which is relative to the base about a release axis of rotation running orthogonally to a gliding board plane is rotatable, coupling means arranged on the binding body, which are designed to be in engagement with a heel section of a gliding board shoe in a departure position of the gliding board binding in order to hold the gliding board shoe on the gliding board binding, the coupling means in the departure position in a longitudinal direction of the gliding board, in particular in a direction of travel forward, protruding from the binding body, and an Mz release mechanism, which is set up to bias the coupling means into the departure position in such a way that they release themselves from engagement with the sliding board shoe in the departure position upon the action of a force exceeding
  • An important aspect of this solution according to the invention is therefore to bias the coupling means into the down position by exerting a tensile force on the cam body.
  • the spring arrangement can have a cable element which is designed to transmit the tensile force to the cam body.
  • a cable element can be deflected at almost all positions of the heel unit, which makes a variety of arrangement options possible for the elements of the spring arrangement.
  • the spring means can be arranged almost anywhere and the spring force of the spring means can be transmitted in a favorable manner through the appropriately guided or deflected cable element and exerted at the required location. This configuration allows many different design options and with a clever structural arrangement of the spring means and the cable element, a considerable amount of installation space can be saved.
  • the heel unit can be designed to be particularly compact, particularly in the longitudinal direction of the gliding board.
  • a first end section of the cable element can preferably be attached to the spring means. This can preferably be done via a loop formed at the end of the rope or in a similar manner.
  • a direct connection is preferably provided in order to be able to achieve direct force transmission without major friction losses.
  • the first end section of the cable element can also be attached to the spring means via an intermediate connecting element.
  • a second end section of the rope element can be fixed to the binding body.
  • a fixation of the rope element on the binding body takes place via a seal or the like arranged on the end section of the rope element, with the rope element initially being guided through a through hole or another recess in the binding body.
  • any other thickening can also be provided on the end section of the cable element.
  • a connection via a loop formed at the end of the rope, which is hooked to a projection on the binding body, or another suitable connection - directly or via an intermediate connecting element - is also conceivable.
  • the cable element can transmit the spring force of the spring means to the cam body in order to provide the triggering force for the Mz triggering mechanism, which in turn enables a variety of design options for the spring arrangement, a compact design of the heel unit achieved and still a relatively large triggering force can be provided.
  • the binding body can have at least one guide section for the rope element.
  • the rope element can be guided and deflected around the binding body, for example, by guide sections on the binding body. If the binding body itself acts as a deflection element, the rope element remains close to it and a compact design can again be achieved.
  • the position of the rope element can be determined relatively precisely by the at least one guide section for the rope element on the binding body and can be steered in such a way that the rope element does not come into a range of movement of other movable elements of the heel unit with which the rope element is not intended to interact and whose movement affects the rope element should not affect. So possible Malfunctions of the heel unit can be prevented in a particularly simple manner by the at least one guide section for the rope element provided on the binding body.
  • the spring means can be a torsion spring.
  • Torsion springs are used to create torque or accumulate rotational energy in a structure.
  • other terms such as torsion spring or torsion spring are applicable for the type of spring “torsion spring”. These terms can equally be used in place of "torsion spring”.
  • An advantage of using a torsion spring as a spring means for the spring arrangement is, for example, that torsion springs can be designed to be relatively compact in the direction of a central axis of their windings and the spring arrangement therefore requires less installation space, particularly in the longitudinal direction of the sliding board, whereby the entire arrangement of the heel unit can be made more compact.
  • a first spring leg of the torsion spring can be supported on a section of the binding body and/or a second spring leg of the torsion spring can be supported on a section of the cable element, in particular on a first end section of the cable element be.
  • Supporting the spring legs of the torsion spring on the binding body or on the cable element allows direct force transmission between the spring arrangement and the binding body on which the coupling means are arranged. This force transmission can take place in an advantageous and space-saving manner through the flexible cable element, which can be deflected at suitable points in order to obtain a particularly compact overall arrangement.
  • the spring means can be a tension spring.
  • a tension spring is less compact along the central axis of its spring coils than, for example, a torsion spring.
  • a first spring end of the tension spring can be assigned to the binding body and/or a second spring end of the tension spring can be assigned to the cam body.
  • “Assigned” in this context means that the first spring end of the tension spring can be arranged or attached to the binding body either directly or via an intermediate element and the second spring end of the tension spring can be arranged or attached to the cam body either directly or via an intermediate element. Fastening the spring ends of the tension spring to the binding body or to the cam body allows direct force transmission between the spring arrangement and the binding body on which the coupling means are arranged.
  • spring end sections at the spring ends of the tension spring can be designed as hook sections or the like and hooked onto a section of the binding body or the cam body in order to transmit the triggering force to the coupling means arranged on the binding body.

  • the triggering force for the Mz triggering mechanism is provided by a torsion spring.
  • An advantage of using a torsion spring as a spring means for the spring arrangement is, for example, that torsion springs can be designed to be relatively compact in the direction of a central axis of their windings and the spring arrangement therefore requires less installation space, particularly in the longitudinal direction of the sliding board, whereby the entire arrangement of the heel unit can be made more compact.
  • the torsion spring can also be arranged with the central axis of the spring coils in the longitudinal direction of the sliding board, in the transverse direction of the sliding board or in a direction perpendicular to the plane of the sliding board, which results in a great deal of design freedom. In the present invention, it is particularly intended to arrange the torsion spring with its central axis perpendicular to the plane of the gliding board in order to keep the heel unit compact in the longitudinal direction of the gliding board.
  • Torsion springs are used to create torque or accumulate rotational energy in a structure.
  • type of spring such as torsion spring or torsion spring applies. These terms can equally be used in place of "torsion spring”.
  • a first spring leg of the torsion spring can advantageously be supported on a section of the binding body and/or a second spring leg of the torsion spring can be supported on a section of the Mz trigger mechanism, in particular on a section of the cam body. Supporting the spring legs of the torsion spring on the binding body or on the cam body allows direct force transmission between the spring arrangement and the binding body on which the coupling means are arranged.
  • the first spring leg of the torsion spring presses directly against a section on the binding body and / or the second spring leg of the torsion spring presses directly against a section on the cam body or an element assigned to the cam body in order to provide the triggering force for the Mz triggering mechanism and to be transferred to the coupling means via the torsion spring.
  • the cam body is arranged pivotably on the binding body, in particular about a pivot axis parallel to the sliding board plane and orthogonal to the release axis of rotation or about a pivot axis parallel to the release axis of rotation on the binding body.
  • a pivotable mounting of the cam body enables a defined movement of the same. As a result, a probability of jamming or the like of the cam body on the binding body can be reduced.
  • the overall system is therefore less susceptible to defects and easier to maintain.
  • a displaceable mounting of the cam body is also conceivable, i.e. the invention is not limited to a pivotable mounting of the cam body.
  • a spring preload of the spring means can be adjustable, in particular adjustable by means of an adjusting screw.
  • An adjusting screw can be operated easily using a standard screwdriver. This means that easy handling can be ensured with regard to an adjustment option for a spring preload of the spring means of the spring arrangement of the Mz trigger arrangement of the heel unit.
  • the coupling means can in particular be two coupling pins arranged essentially next to one another, which are designed to engage in recesses in the heel section of the gliding board shoe in order to hold the gliding board shoe on the gliding board binding, with at least one of the coupling pins being movable relative to the other coupling pin, in particular in one can be movable in a plane essentially parallel to the sliding board plane.
  • both coupling pins can be moved away from each other against an elastic clamping force in the plane essentially parallel to the sliding board plane.
  • a frontal or My release can also be provided in order to obtain a fully-fledged safety binding with Mz and My release.
  • My is the torque during a forward tilt, for example a forward fall.
  • the sliding board shoe is released when a torque around the sliding board transverse direction (y-direction) is applied, if this torque exceeds a My release torque.
  • a spring preload of a spring means of a My release mechanism can also be adjustable in order to be able to adapt the My release torque to various user parameters such as body weight, riding ability, age, sliding board shoe length, etc.
