Definitions

  • the present invention relates to a binding system for a touring ski binding comprising a toe piece device and a rear piece device for receiving a ski boot.
  • Ski bindings for touring skis are primarily distinguished by the fact that they can be switched between an ascent mode and a downhill mode compared to conventional ski bindings.
  • Ascent mode only the front area of the ski boot is fixed on the ski, so that the rear area of the ski boot can be lifted off the ski and placed on it.
  • the front area of the ski boot rotates about a horizontal axis of a fastening web that is perpendicular to the longitudinal direction of the ski.
  • downhill mode both the front and the rear of the ski boot are firmly attached to the ski.
  • the downhill performance of a touring ski is usually limited by the need to provide an ascent function.
  • Known touring binding systems generally have a higher standing height than pure downhill binding systems.
  • the components that are required for the ascent position also require a comparatively higher amount of material, which can lead to a higher weight of the touring bindings.
  • Conventional touring binding systems can be roughly divided into the categories of bridge binding systems and pin systems.
  • the bar binding systems are characterized by the fact that the ski boot is clamped between the front and rear jaws both in the downhill position and in the ascent position.
  • the front and rear jaws are attached to a bar, with the front part of the bar being fixed to the ski both in the ascent and in the downhill position.
  • the front part of the web In the ascent position, the front part of the web can rotate about a horizontal axis running perpendicular to the longitudinal axis of the ski.
  • the rear end can be fixed on the ski in the downhill position and lifted off the ski in the uphill position.
  • the bindings can be divided into a front unit and a rear unit.
  • the ski boot In the ascent position, the ski boot is only supported by the front unit so that it can rotate about a horizontal pivot axis running perpendicular to the longitudinal axis of the ski.
  • the pin systems known from the prior art have the considerable disadvantage that a lateral release behavior, in which the ski boot can loosen laterally from the binding in downhill mode with an increased force, is impaired by the pins, which penetrate into the ski boot.
  • a binding system for a touring ski binding comprising a toe piece device and a heel piece device for accommodating a ski boot, the ski boot having a heel part and a forefoot part, at least one bar being arranged in or on the forefoot part, the bar axis of the bar being perpendicular to the longitudinal axis of the boot runs, with the longitudinal axis of the shoe extending from the heel part to the forefoot part, with the toe piece device comprising a holding device with a holder and a locking system, with the holder having a hook-shaped receptacle for receiving the bridge of the ski boot, which is aligned opposite to the longitudinal axis of the shoe, with the holder Bridge at least partially encompasses and thus accommodates the bridge of the ski boot, with the locking system being suitable for locking the bridge of the ski boot in the holder so that it can rotate about the bridge axis, with the rear jaw device having a lever mechanism which is suitable for fixing the heel part of the ski boot, wherein
  • the front jaw device in a downhill mode, is open and the rear jaw device is closed, so that the posture can accommodate the web of the ski boot and the lever mechanism of the rear jaw device can fix the heel part of the ski boot, with the rear jaw device using the lever mechanism exerting contact pressure on the heel part of the ski boot along the longitudinal axis of the shoe , so that the web is pressed into the holder of the front jaw device, and the ski boot is secured against translation against the longitudinal axis of the boot.
  • the touring ski binding can be mounted on a ski, for example by means of a screw connection.
  • the ski surface normal which runs orthogonally to the longitudinal axis of the boot and orthogonally to the web axis, is perpendicular to the ski surface.
  • the relative positions of the various parts of the touring ski binding are therefore described below using the aforementioned axes.
  • the ski boot has a heel portion and a forefoot portion.
  • the heel part and the forefoot part are located on the ski boot according to the anatomy of a human foot.
  • the heel part and the forefoot part mean the outermost areas of the ski boot. Accordingly, the longitudinal axis of the shoe runs from the heel to the forefoot area of a foot and thus corresponds to the typical walking direction of a person.
  • the ski boot can have an edge that can withstand particularly high mechanical loads, which is suitable for transmitting a force, in particular a longitudinal holding force, in the direction of the longitudinal axis of the boot to the ski boot.
  • the edge can also protrude from the heel part of the ski boot in the opposite direction to the longitudinal axis of the boot, in order to ensure both a large contact surface for the lever mechanism and to offer different contact surfaces for transverse holding forces, in particular transverse holding forces that act orthogonally to the longitudinal axis of the boot and parallel to the normal to the ski surface.
  • At least one bar is arranged in or on the forefoot part of the ski boot.
  • the web is a preferably cylindrical component whose cylinder axis runs perpendicular to the longitudinal axis of the shoe.
  • a cylindrical design of the web makes it possible, in particular, to rotate the ski boot in the toe piece device in a particularly simple manner. Such a simple rotation makes it possible to guide the ski under the foot or the boot particularly comfortably and in a way that is gentle on the joints during the natural course of movement when running. This leads to a stabilized gait off-road and thus also to increased safety.
  • the web it is also possible for the web to have a different geometric shape.
  • the web can have an elliptical cross section or have a cross section that is round in sections.
  • the rounding of the bar is always arranged in such a way that low-friction rotation of the bar in the toe piece device is possible and/or a particularly advantageous transmission of force from the bar to the ski, for example when lifting the ski and driving the ski, is made possible.
  • the ski boot does not have to be rotated completely about the web axis, but rather only a limited angular range has to have the advantageous properties due to the natural movement process when walking.
  • the web has a finite length, typically less than the width of the forefoot.
  • the bridge can be completely or partially embedded in the sole of the ski boot or lie completely outside the sole and be fastened to the ski boot with a stiffened bridge holding structure, for example.
  • a translation along the bridge axis is limited in the toe device either by the sole or by the bridge holding structure of the ski boot.
  • the ski boot accommodated in the front jaw device cannot be moved in a translatory manner, for example shifted, along the web axis.
  • the hook-shaped receptacle of the holder can be adapted to the rounding or the geometric shape of the web, so that a form-fitting contact between the web and the holder is made possible. This allows a particularly stable and rigid connection between the ski boot and the toe unit, so that the ski can be controlled particularly well.
  • the holder at least partially encompasses the web.
  • a hook that forms the hook-shaped receptacle is only suitable for providing a transverse holding force and a longitudinal holding force.
  • the holder can only protrude from the top of the bar to the front of the bar (viewed in the direction of the longitudinal axis of the shoe in the plane of the longitudinal axis of the shoe and the normal to the ski surface).
  • a transverse holding force can already be generated parallel to the normal to the ski surface and a longitudinal holding force can also be generated along the longitudinal axis of the boot.
  • a holding force along the negative ski surface normal is realized by the ski surface, so that the holder does not have to encompass the lower area of the web. Accordingly, the web is held by the holder when the translation of the ski boot along the positive normal to the ski surface and along the longitudinal axis of the boot is prevented.
  • the hook-shaped receptacle for receiving the bridge of the ski boot is aligned opposite to the longitudinal axis of the boot.
  • At least one translation of the ski boot in the direction of the longitudinal axis of the boot can be prevented, since the hook serves as a mechanical barrier for the bar. Furthermore, a translation of the ski boot counter to the direction of the normal to the ski surface can be prevented. This can be done either through the shape of the mount or through the locking system.
  • the holder with a hook-shaped receptacle can also be designed in the form of a hook system with an opening.
  • the locking system is arranged in the direction of the longitudinal axis of the boot in front of the mount on the ski.
  • a translation of the web against the longitudinal axis of the shoe can be prevented by the holder.
  • a translation of the ski boot perpendicular to the web axis can thus be prevented altogether.
  • a translation of the ski boot along the web axis is also prevented by the design.
  • the ski boot that is held and locked in the holder can be rotated about the web axis.
  • the heel device has a lever mechanism that is suitable for fixing the heel part of the ski boot.
  • the lever mechanism can exert a longitudinal holding force on the ski boot, for example pressing the ski boot along the longitudinal axis of the boot into the holder of the toe piece device.
  • a transverse holding force that presses the heel part of the ski boot in the direction of the ski surface is also useful.
  • a lever mechanism can mean that the lever mechanism comprises at least two components which are movably fastened to one another and can be moved in relation to one another in order in this way to bring about a holding force on the ski boot.
  • a movable attachment can mean that the components of the lever mechanism can be rotated and/or displaced.
  • the binding system for a touring ski binding has two modes, namely an ascent mode and a descent mode.
  • the ascent mode of the touring ski binding is suitable for this to ski or climb with the ski attached to the ski boot, in particular to climb a mountain or slope.
  • the downhill mode is suitable for attaching the ski to the ski boot, so that safe downhill skiing with a high degree of control of the ski is made possible.
  • the toe device In the ascent mode, the toe device is closed and the heel device is opened.
  • a closed toe device can mean that the toe device can rotatably lock the bridge, wherein the locking system can secure the bridge against translation against the longitudinal axis of the shoe, as already described above.
  • the heel device in ascent mode, the heel device is open. As a result, the heel device does not fix or hold the heel part of the ski boot, so that a rotation of the ski boot about the bridge axis is made possible in the first place.
  • the toe device In the descent mode, the toe device is open and the heel device is closed.
  • An open front jaw device can mean that only the holder can accommodate the bridge of the ski boot, but the locking system does not lock the bridge in a rotatable manner.
  • An open toe piece device therefore allows the bridge to be guided into the holder or the bridge to be removed from the holder. In particular in the event of a fall in downhill mode, this enables the shoe to be released from the binding, in particular from the toe piece device.
  • the lever mechanism of the heel device can fix the heel part of the ski boot.
  • the heel device with the lever mechanism exerts a contact pressure on the heel part of the ski boot along the longitudinal axis of the boot, as already described above.
  • the contact pressure presses the bar into the holder of the toe piece device.
  • the holder In downhill mode, the holder therefore secures the web against translation in the direction of the longitudinal axis of the boot and along the normal to the ski surface.
  • the web is secured against translation against the longitudinal axis of the boot, in that the lever mechanism presses the heel part of the ski boot in the direction of the longitudinal axis of the boot.
  • the ski boot In the downhill mode, the ski boot is therefore not rotatably mounted, but fixed in its position relative to the ski.
  • the binding system for a touring ski binding thus has the advantage that the mobility of the ski boot in an ascent mode is analogous to the mobility of a cross-country ski boot. At the same time, a high level of stability and safety can be guaranteed in a downhill mode, since the ski boot can be held firmly in the touring ski binding. At the same time, however, the holder can allow the ski boot to be detached from the open toe unit in downhill mode, so that injuries in the event of a fall can be avoided or reduced.
  • the locking system and the holder are displaced relative to each other when locking. Both the locking system and the bracket can be moved. Alternatively, only the locking system or the bracket can be moved. In particular, a relative displacement means that the locking system and the bracket are not rotated in relation to one another.
  • the locking system and the holder are displaced along the longitudinal axis of the boot relative to one another, in particular parallel to the plane of the ski surface.
  • the locking system is fixed in place on the ski and the holder is displaceable.
  • the holder can be moved in the aforementioned manner.
  • the holder can be moved towards or away from the locking system.
  • the holder in a closed mode of the toe device the holder is arranged adjacent to the locking system, while in an open mode it is arranged at a distance from the locking system.
  • the toe piece device further comprises a toe piece lever mechanism, the holder being displaceable by means of the toe piece lever mechanism.
  • a toe piece lever mechanism can act by rotating components of the mechanism about their attachment points to exert a force along or against the longitudinal axis of the shoe.
  • the (rotational) forces acting on the lever are deflected by the toe jaw lever mechanism to a transverse force, preferably a transverse holding force.
  • a toe piece lever mechanism can move the holder in the direction of the locking system by actuating a lever.
  • the lever of the toe jaw lever mechanism can have two positions, so that a closed and an open state of the toe jaw device can be realized.
  • the toe piece device further comprises a toe piece spring mechanism, the holder being displaceable by means of the toe piece spring mechanism.
  • the bracket can also be moved by a toe spring mechanism.
  • the toe piece device can be pretensioned by the toe piece spring mechanism.
  • a spring can be arranged between the locking system and the holder, with the spring being able to push the holder and the locking system away from one another.
  • the spring it is also possible for the spring to move the holder and the locking system relative to one another.
  • a lever position of the toe lever mechanism may place the toe assembly in a closed condition.
  • a toe piece lever mechanism can then be used, for example, as a safety release when the spring is biased by the closed state of the toe piece device.
  • the spring would push the locking system and bracket apart.
  • the retainer can be pushed away from the locking system by the toe spring mechanism, allowing the bridge and ski boot to disengage from the toe assembly.
  • a safety release can be implemented in ascent mode.
  • the spring can be arranged in such a way that the holder and the locking system are displaced in relation to one another.
  • the spring is in a tensioned state when the lever position of the toe-jaw lever mechanism is in a closed state.
  • the spring serves as a safety release both in downhill mode and ascent mode, if a force in the direction of the longitudinal axis of the shoe exceeds a predefined threshold value, such as in the event of a fall, the bracket is pushed away from the locking system and the bridge and ski boot can be released from the toe piece device.
  • the locking system has a stop, with the holder being pressed against the stop by means of the front jaw spring mechanism in the ascent mode.
  • the holder and the locking system can be placed at a predefined distance, so that the holder can lock the web in a rotatable manner.
  • the holder is U-shaped or L-shaped.
  • This has the advantage that the web of the ski boot is secured against translation along or against the normal to the ski surface due to the parallel sides of the U-shaped holder.
  • the rounding of the U-shaped holder allows a round bar to rotate when it is accommodated in the U-shaped holder.
  • the U-shaped design of the bracket is particularly advantageous when using a hook system.
  • the alternative embodiment with an L-shaped holder allows the bridge of the ski boot to rotate in the ascent mode, with the bridge still being secured against translational movement along or against the normal to the ski surface in the ascent mode and in the descent mode.
  • an L-shaped bracket is advantageous in terms of manufacture.
  • the locking system includes a locking plate that is configured to at least partially cover the hook-shaped receptacle of the mount.
  • a locking plate can be cuboid, so that the U-shaped bracket can be closed over its entire surface.
  • the locking plate can itself also have a pronounced rounding opposite to the longitudinal axis of the shoe, so that the web is positively received by the locking plate and the holder and locked in a rotatable manner.
  • An L-shaped locking plate is advantageous when using an L-shaped holder, since the web is held in a non-positive manner in the hook-shaped receptacle and locked in a rotatable manner. Such a form-fitting configuration enables better power transmission in ascent mode.
  • the bridge of the ski boot is offset along or counter to the longitudinal axis of the boot in the ascent mode compared to the descent mode. This can be achieved in particular in that the holder is located behind the locking system in the open position of the front jaw device in the direction of the longitudinal axis of the shoe.
  • the heel device has a safety release in downhill mode.
  • a safety release allows, for example, when a predefined force is exceeded, to release the rear-jaw device, ie to switch the rear-jaw device from a closed to an open state.
