Definitions

  • the invention relates to a ski binding which is suitable for ski tourers and freeriders and which, while being lightweight, ensures reliable release in the event of a fall.
  • Tourers and freeriders want ski bindings with a low weight.
  • the ski boot is firmly clamped between a toe holder and a heel holder for skiing.
  • the connection to the ski is released in the heel area of the shoe, so that the shoe can pivot about a transverse axis located in the area of the toe holder while the connection to the toe holder is still in place.
  • Bindings are known, for example from the WO 2007/060219 A1 and the EP 2 329 864 A2 , in which the toe holder and the heel holder are connected to one another via a touring plate.
  • the touring plate is releasably connected to the ski in the area of the heel holder, so that in the released state the touring plate and the heel holder can pivot together about the said transverse axis.
  • bindings were developed that do not require a touring plate.
  • the heel holder With such plateless bindings, for example from the EP 0 199 098 B1 and the AT 402 020 B are known, the heel holder remains connected to the ski for walking, while the connection between the ski boot and heel holder is released.
  • the swivel joint required for walking is usually formed directly between the ski boot and the toe holder in that the toe holder engages in receptacles in the ski boot in the transverse direction.
  • the heel holder has freely projecting support pins which engage in corresponding recesses in the heel area of the ski boot and are movable against spring force from engagement with the ski boot in order to be released.
  • the support pins hold the ski boot firmly on the ski in the heel area, but in such a way that a clear distance remains between the bottom of the ski boot and the top of the ski in order to prevent snow clogging.
  • the ski boot is thus supported in the heel area in the vertical direction towards the ski on the support pins and is held in the opposite direction by the support pins. Loosening the connection, to unbuckle the ski or to walk, turns out to be tedious. Furthermore, reliable release in the event of a fall is not guaranteed with the desired level of safety.
  • the WO 2009/153615 A1 relates to a heel holder for a touring binding.
  • the heel holder comprises a support device for a rear part of the shoe sole, which is firmly connected to a base of the heel holder or the ski and cannot be moved relative to the heel holder.
  • the support device keeps the sole at a distance from the base or ski surface and thus enables the heel holder to be locked more easily if a layer of snow sticks under the sole when getting into the binding.
  • a ski binding with a climbing aid is known in which the base has a contact surface or support device for the in the heel holder held rear end of a ski boot forms. The base can be moved back and forth in the longitudinal direction of the ski relative to the base.
  • the EP 1 438 993 A1 relates to a touring ski binding with a toe holder for movably holding a front region of a ski boot and a heel holder.
  • the binding In the skiing direction in front of the heel holder, the binding has a rear sole support for the ski boot which fixes the ski boot in the state held in the binding above a base of the heel holder.
  • the WO 2012/024809 A1 relates to a touring heel binding with a dynamic glide area.
  • the invention relates to a ski binding according to claim 1. Further refinements of the invention are specified in the dependent claims.
  • the invention is based on a ski binding which has a toe holder for holding a front area of a shoe and a heel holder for holding a rear area of the shoe.
  • the heel holder comprises a base that is connected to a ski or can be connected to the ski by mounting.
  • the base is advantageously flat, for example in the form of a plate or rail.
  • the heel holder further comprises a bearing structure that protrudes from the base in a vertical direction of the binding, and a cantilevered support device on which the rear area of the boot can be supported in the vertical direction, so that when the base is connected to the ski, at least in the rear boot area in the supported state There is a clear gap between the boot and the ski.
  • the heel holder can be transferred from a released state to a closed state and from the closed state back to the released state.
  • the heel holder can be firmly connected to the ski, at least as far as the use of the ski is concerned, so it does not have to be detached from the ski when walking with the ski strapped on, as is the case with touring bindings with a swiveling touring plate.
  • a touring plate that is detachable and movably connected to the ski in the released state can be omitted.
  • the ski binding according to the invention can therefore advantageously be a touring-suitable, plateless ski binding.
  • the toe holder is designed in such a way that it keeps the shoe movable, preferably pivotable, preferably by forming a hinge, in the front shoe area for walking with the ski strapped on.
  • the toe holder can be used like a toe holder of known bindings, for example the touring binding of the EP 0 199 098 B1 be formed accordingly.
  • He can be a have movable, for example pivotable, engagement member for forming a joint, preferably a swivel joint, directly with the shoe.
  • it can also be pivotably connected to the ski itself.
  • the axis of rotation of the swivel joint is preferably a transverse axis of the binding, that is to say an axis which extends transversely to the vertical direction and transversely to a longitudinal direction of the binding pointing from the heel holder to the toe holder.
  • the left and right engagement members can be pivotally connected to the base of the toe holder. They are preferably pivotable about an axis pointing in the longitudinal direction.
  • the toe holder further comprises a spring device, against the resetting spring force of which the at least one engaging member or the preferably several engaging members of the toe holder can be moved from a closed position, in which they can hold the shoe in an articulated manner, into a release position.
  • the heel holder has, in addition to the support device, a hold-down device, which is movable to and fro relative to the bearing structure between a closed position corresponding to the closed state of the heel holder and a release position corresponding to the released state of the heel holder, preferably pivotable to the shoe in the closed position on the Hold down the support device and release it in the release position.
  • the heel holder comprises a spring device which has at least one hold-down spring, against the restoring force of which the hold-down can be moved from the closed position into the release position.
  • the hold-down device is preferably designed in such a way that in the closed position it presses from above onto a free upper side of the shoe in the rear shoe area, for example an upper side of a protruding shoe sole, and thereby presses the lower side of the shoe onto the support device.
  • the mode of operation and also the shape of the hold-down device according to the invention can correspond to the mode of operation of a sole holder of touring-suitable safety bindings for holding down the shoe, as for example from FIG EP 2 329 864 A2 are known.
  • a heel holder with a support device and a hold-down device has good tilting rigidity, especially when going downhill, since the heel holder due to the support device cannot or essentially cannot move transversely to a skiing direction and is additionally at the same time tensioned in the direction of the ski surface.
  • a distance between the support device and the hold-down device can be invariable, at least in the situation in which the support device and the hold-down device hold the ski boot in a driving position on the ski.
  • the distance corresponds to a distance between an engagement area for the hold-down device and an engagement area of the support device on the ski boot sole.
  • the support device and the hold-down device are essentially not elastically deformable, but rather are designed to be rigid.
  • a snow span of the heel holder can be approximately 6 mm, for example.
  • the snow span height is to be understood as a height of the snow plug which is formed, for example, between the base of the heel holder and the ski boot sole.
  • the heel holder or the hold-down device closes reliably up to the specified snow height of approx. 6 mm. In this position, the support device can already enter into a supporting connection with the ski boot, so that the ski boot is securely held in the heel holder. If the height of the snow plug decreases, the spring device of the heel holder or the hold-down spring can, so to speak, "push down" the hold-down device until the ski boot stands directly on the base at a height of the snow plug of 0 mm.
  • the invention succeeds in combining the essential advantage of plateless touring bindings, namely their low weight, with increased releasing reliability and, for driving down, advantageously stiff mounting of the shoe.
  • the invention separates the function of supporting at a clear distance from the ski and the base, if this extends under the support device, from the function of holding down by providing a support device serving for support and a hold-down device which ensures that the boot is pressed onto the support device when the binding is closed. Due to the interaction of the hold-down device and the support device, the shoe is held more rigidly in the closed state of the heel holder than in the known plateless touring bindings.
  • the support device and the hold-down device are preferably designed in such a way that the hold-down device presses directly onto the shoe and the latter directly onto the support device, preferably from above.
  • the support device is of its dual function, which it in the Must meet plateless touring bindings of the type mentioned, relieved. It preferably only has to fulfill its actual function, the support function.
  • the binding according to the invention is also more convenient to handle, since the laborious opening of the support device when switching from skiing to walking with the ski strapped on is no longer necessary and instead only a hold-down device free of the support function has to be moved from the closed position to the release position.
  • the support device basically protrudes upwards from the base in the form of a support structure that exposes the shoe and can protrude in this sense, for example in the shape of a pin
  • the support device protrudes from the bearing structure.
  • the support device protrudes from a closing unit which includes the hold-down device.
  • the support device can be moved to and fro relative to the base between an active position and an inactive position.
  • the heel holder can have a lever on an outside, for example, which is connected to the support device and can be pivoted together with the support device. If the support device assumes the active position, the rear area of the shoe can be supported on the support device. If the support device assumes the inactive position, the boot is free from the support device and can be pushed through to the top of the ski or the base while walking.
  • the mobility between the active position and the inactive position can in particular be pivoting mobility or translational mobility or include such mobility.
  • the support device can be movable back and forth between the two positions together with the hold-down device or the bearing structure.
  • the support device can also be arranged in such a way that it can be moved into different inactive positions.
  • the different inactive positions all have the common property that when the support device is in the respective inactive position, the shoe can be moved freely from the support device to the ski or the base or any other contact point located on the top of the ski.
  • the support device In the inactive position or in the different inactive positions, the support device cannot exercise a support function for the shoe, at least not in relation to the vertical direction.
  • the support device in which the support device protrudes from the bearing structure, can advantageously also be supported directly on the bearing structure in the vertical direction. It can be molded in one piece with the bearing structure, for example as an injection-molded part made of plastic. Instead, it can also be joined immovably to the bearing structure, for example by means of a screw connection or an adhesive connection or another suitable joining connection. In preferred embodiments, the support device can move transversely relative to the bearing structure, ie transversely to the longitudinal direction and vertical direction of the binding, for example orthogonal to the longitudinal direction and to the vertical direction.
  • the support device can comprise a first support pin protruding from the bearing structure and a second support pin protruding from the bearing structure, which can cooperate with correspondingly designed shoes in the rear area, in that the first and the second support pin each into a corresponding receptacle in the rear The area of such a shoe protrudes when the shoe is supported on the support device.
  • at least one of the support pins can be movable relative to the bearing structure and the other of the support pins can be moved in the transverse direction, and thereby a distance measured in the transverse direction between the support pins can be varied.
  • both the first and the second support pin can move transversely relative to the bearing structure.
  • the respective transversely movable support pin does not have to be movable against a restoring spring force, since the support device in the closed state of the heel holder is free or at least can be free from the function of holding down according to the invention.
  • the at least one or the preferably two support pins can thus be freely transversely movable in order to be able to interact with the known, corresponding shoes in fulfilling the support function.
  • the support device is preferably movable relative to the hold-down device and preferably independently of the hold-down device.
  • the hold-down device can be movable to and fro relative to the support device, preferably independently of the support device, between the closed position and the release position.
  • the support device in which the support device protrudes from a closing unit comprising the hold-down device, can be immovably connected to the hold-down device.
  • the hold-down device and the support device can, for example, be molded in one piece, for example from plastic by injection molding. They can also be immovably connected to one another by means of a joint connection, for example by means of an adhesive connection or a screw connection. Since the support device should not interfere with walking with the ski strapped on, it is advantageous in such designs if the support device and the hold-down device can be moved together from an active position, which they assume when the heel holder is closed, into an inactive position, in which the ski boot is free from the hold-down device and the support device.
  • the support device can be moved back and forth relative to the hold-down device, so that the support device can be moved from an active position to an inactive position when the hold-down device is in the release position.
  • the shoe connected to the ski via the toe holder is free from the heel holder in such developments if, on the one hand, the hold-down device is in the release position and, on the other hand, the support device is in the inactive position.
  • the support device acts as a tread spur to close the heel holder
  • the support device is movable, preferably pivotable, relative to the bearing structure from an upper position to a lower position, and is coupled to the hold-down device in such a way that a Movement of the support device from the upper to the lower position causes the hold-down device to move from the release position into the closed position.
  • the support device can be immovably connected to the hold-down device, for example formed in one piece or firmly joined.
  • a support device serving as a tread spur is movable relative to the hold-down device in such a way that it can be moved into the inactive position when the hold-down device is in the release position. It is preferably movably arranged on the closing unit comprising the hold-down device, preferably pivotably. In such embodiments, the support device can advantageously be moved into a stop contact with the closing unit, so that when the support device continues to move in the stop contact, the closing unit and thus the hold-down device together are moved from the release position into the closed position.
  • the hold-down device can fulfill the kicking function by the skier stepping on the support device with the shoe and pressing down, as known from safety bindings, against the spring force of the spring device of the heel holder, preferably the hold-down spring, moves the support device downwards and in the stop contact the hold-down device moves into the closed position. If, when the heel holder is opened, the hold-down device is moved into the release position and the shoe is lifted off the support device, the support device can be moved into the inactive position relative to the hold-down device. In this way, it is possible to switch from moving to walking without further changing the position of the hold-down device, just by moving the support device into the inactive position.
  • a support device acting as a tread does not advantageously require any special footwear with a receptacle for the protruding support device, since the shoe can rest with its free underside on the support device.
  • a support device which is formed to interact with one or more receptacles in the rear shoe area, can also be arranged to act as a tread spur by being coupled to the hold-down device in the manner explained.
  • the heel holder can advantageously also have a tread spur in addition to the support device in order to be able to close the heel holder by getting into the binding, so that no additional actuation of the heel holder is required for the closing.
  • the additional tread spur can be fixed, immovable, connected to the hold-down device, for example joined or formed in one piece, or correspondingly coupled to the hold-down device, as is basically known for pure downhill bindings.
  • Such a tread spur can in particular be part of a closing unit forming the hold-down device.
  • the additional tread spur is advantageously relieved from the shoe by the support device, preferably released, so that the weight of the driver is at least substantially absorbed by the support device when the ski is buckled on.
