Description

The present invention relates to a heel unit for a touring binding, comprising a binding body which is suitable for holding a heel section of a touring boot in a downhill position of the heel unit and for releasing the heel section of the touring boot in a touring position of the heel unit so that the touring boot can lift off the heel unit, and a climbing aid which is adjustable between an active position and a passive position, wherein in the touring position of the heel unit the climbing aid supports the heel section of the touring shoe in its active position at a predetermined height above a gliding board level. Furthermore, the present invention relates to a heel unit for a touring binding, comprising a binding body which is suitable for holding a heel section of a touring boot in a downhill position of the heel unit and for releasing the heel section of the touring boot in a touring position of the heel unit so that the touring boot can lift off the heel unit , a first climbing aid, which is adjustable between an active position and a passive position, wherein in the touring position of the heel unit, the first climbing aid in its active position supports the heel section of the touring boot at a predetermined height above a gliding board level, and a second climbing aid, which between an active position and a passive position is adjustable, wherein in the touring position of the heel unit, the second climbing aid in its active position from the heel section of the touring shoe at a predetermined height above a gliding board level based, which is higher than the predetermined height of the first climbing aid. Such heel units are known. A climbing aid is used in ski mountaineering to compensate for changes in the slope of the terrain while walking. Steep terrain can be compensated for by switching on the climbing aid and thus increasing the support height for a heel section of a touring boot. In conventional touring bindings, one or two climbing aids are often provided, so that in addition to a so-called zero position in which no climbing aid is switched on and a heel section of the touring boot rests directly on a ski, a base or a brake pedal of the heel unit of the touring binding, one or two further support heights can be adjusted in that the climbing aid is adjusted by the user from a passive position to an active position.

The climbing aid is often pivotably mounted on the binding body of the heel unit and, in order to be adjusted from the passive position to the active position, has to be swiveled into the active position by the user by hand or with a ski pole. Here the user has to guide the climbing aid, in particular by pulling with a ski pole, the entire movement path or a large part of the movement path from the passive position to the active position. In particular in adverse conditions, which often prevail when ski mountaineering in the form of ice and snow, this adjustment can be quite difficult, also because climbing aids are made up of increasingly smaller and more difficult-to-grip components due to weight savings.

If, for example, two climbing aids are provided, the second climbing aid is often also pivotably mounted on the binding body, preferably on the same axis as the first climbing aid. The above-mentioned problems also arise when adjusting the second climbing aid from the passive position to the active position. In the case of two climbing aids, a further disadvantage can be that if the user inadvertently moves the first climbing aid from the passive position to the active position the second climbing aid is also grasped and adjusted so that the correct support height for the touring shoe heel section cannot be found at once.

Heel units with other types of climbing aids are also known, all of which, however, are either difficult to operate or have complex, relatively heavy and / or expensive to manufacture, for example pneumatically, hydraulically and / or electronically operating arrangements.

Against this background, it is an object of the present invention to provide a heel unit for a touring binding which enables a simplified operation of one or, if necessary, several climbing aids, which is comparatively simple in construction and is lightweight.

According to a first aspect of the present invention, the object on which the invention is based is achieved by a heel unit for a touring binding, comprising a binding body which is suitable for holding a heel section of a touring shoe in a downhill position of the heel unit and the heel section of the touring shoe in a touring position of the heel unit to release so that the touring shoe can lift off the heel unit, and a climbing aid which is adjustable between an active position and a passive position, wherein in the touring position of the heel unit, the climbing aid in its active position the heel section of the touring boot at a predetermined height above a The sliding board plane is supported, the climbing aid being biased into the active position by means of an elastic element over its entire path of movement and being lockable in the passive position.

If the climbing aid is pre-tensioned in the active position over the entire movement path and can also be locked in the passive position, it is sufficient To adjust the climbing aid from the locked, passive position to the active position, release this lock in order to achieve an adjustment. The climbing aid no longer has to be guided over its entire path of movement or part of the path of movement, but it is sufficient to release a locking mechanism, which can be present as a latching or hook mechanism, for example. All locking options are conceivable here. In particular, the lock can be released by pressing on the climbing aid with a ski pole, for example. By pretensioning the climbing aid into the active position, the climbing aid moves automatically into the active position after the lock is released. The adjustment of the climbing aid takes place semi-automatically, so to speak, and operation of the climbing aid is advantageously simplified.

In a preferred embodiment of the first aspect of the invention, the climbing aid can be pivotably mounted on the heel unit, in particular on the binding body. A pivotable design of the climbing aid can bring the advantages of simple operability and the possibility of a space-saving arrangement. The preload in the active position can be achieved in an advantageous manner by a leg spring as an elastic element, which requires less installation space compared to other springs, such as compression or tension springs.

Alternatively, however, the climbing aid can also be arranged so as to be linearly displaceable on the heel unit, in particular on the binding body. In particular, a climbing aid that is longitudinally displaceable in the ski direction is intended, which, after the lock has been released, can be pushed forward in a simple manner in order to be brought into the active position. The operation of a longitudinally adjustable climbing aid is also very easy.

In particular, the climbing aid can be a first climbing aid and the heel unit can furthermore comprise a second climbing aid, which is adjustable between an active position and a passive position, wherein in the touring position of the heel unit the second climbing aid in its active position puts the heel section of the touring boot at a predetermined height supported on a gliding board level, which is higher than the predetermined height of the first climbing aid.

In this case, the second climbing aid can be mounted on the first climbing aid. Such an arrangement can in turn advantageously simplify the operation of the climbing aids. In addition, if the second climbing aid is mounted on an axis relatively far away from the ski, it can be designed to be smaller and therefore lighter, since less additional height has to be reached from the high point on the first climbing aid for the support surface of the second climbing aid.

In addition, if two climbing aids are provided, the first climbing aid can be locked in the passive position by means of the second climbing aid. In this way, both climbing aids can advantageously be locked in the passive position by only one locking mechanism.

In a particularly advantageous embodiment of the first aspect of the present invention, the first climbing aid and / or the elastic element can be configured to transfer the second climbing aid into a standby position when the first climbing aid is adjusted from the passive position to the active position is located between the passive position and the active position of the second climbing aid. If, when the first climbing aid is adjusted from the passive position to the active position, the first climbing aid takes the second climbing aid along part of the path of movement, i.e. transfers the second climbing aid to a stand-by position, then a shortened one is required for an adjustment of the second climbing aid to the active position Way to overcome. In addition, the second climbing aid in the standby position protrude from the heel unit or from the binding body and thus be easier to grip or operate, while in the passive position it can advantageously lie close to the binding body. In this way, operation of the second climbing aid can be simplified in that it is transferred to the standby position when the first climbing aid is adjusted.

If two climbing aids are provided, the elastic element can preferably provide a spring force both for the first climbing aid and for the second climbing aid. So only one spring is required for both climbing aids and costs and weight can be saved. In particular, the elastic element can transmit the spring force for the first climbing aid directly by being arranged on the first climbing aid, and indirectly transmitting the spring force for the second climbing aid by being arranged on the first climbing aid and the spring force being applied to the first climbing aid second climbing aid transfers. The second climbing aid can, for example, be pretensioned into the active position by the elastic element. In addition, the second climbing aid can assume a stable position in the standby position, in particular due to the interaction of a mating surface of the second climbing aid with a mating surface of the binding body or the like and the elastic element. The exact position of the ready position can be set by means of an angle of the mating surface of the binding body.

According to a second aspect of the present invention, the object on which the invention is based is achieved by a heel unit for a touring binding, comprising a binding body which is suitable for holding a heel section of a touring shoe in a downhill position of the heel unit and the heel section of the touring shoe in a touring position of the heel unit to release, so that the touring shoe can lift off the heel unit, a first climbing aid, which between an active position and a passive position is adjustable, wherein in the touring position of the heel unit the first climbing aid in its active position supports the heel section of the touring boot at a predetermined height above a gliding board level, and a second climbing aid which is adjustable between an active position and a passive position, wherein in the touring position of the heel unit, the second climbing aid in its active position supports the heel section of the touring shoe at a predetermined height above a gliding board level which is higher than the predetermined height of the first climbing aid, the first climbing aid being set up when the first climbing aid is adjusted by from the passive position to the active position to transfer the second climbing aid into a standby position, which is located between the passive position and the active position of the second climbing aid.

If, when the first climbing aid is adjusted from the passive position to the active position, the first climbing aid takes the second climbing aid along part of the path of movement, i.e. transfers the second climbing aid to a stand-by position, then a shortened one is required for an adjustment of the second climbing aid to the active position Way to overcome. In addition, the second climbing aid can protrude from the heel unit or from the binding body in the standby position and thus be easier to grip or operate, while in the passive position it can advantageously lie close to the binding body. In this way, operation of the second climbing aid is simplified in that it is transferred to the standby position when the first climbing aid is adjusted.

In one embodiment of the second aspect of the present invention, the first climbing aid can be pivotably mounted on the heel unit, in particular on the binding body. A pivotable design of the climbing aid can bring the advantages of simple operability and the possibility of a space-saving arrangement. The preload in the active position can be carried out in an advantageous manner by a leg spring elastic element can be achieved, which compared to other springs, such as compression or tension springs, requires less installation space.

In an alternative embodiment of the second aspect of the present invention, the first climbing aid can be mounted in a linearly displaceable manner on the heel unit, in particular on the binding body. In particular, a climbing aid that is longitudinally displaceable in the ski direction is intended, which, after the lock has been released, can be pushed forward in a simple manner in order to be brought into the active position. The operation of a longitudinally adjustable climbing aid is also very easy.

The second climbing aid can particularly preferably be mounted on the first climbing aid. Such an arrangement can in turn advantageously simplify the operation of the climbing aids. In addition, if the second climbing aid is mounted on an axis relatively far away from the ski, it can be designed to be smaller and therefore lighter, since less additional height has to be reached from the high point on the first climbing aid for the support surface of the second climbing aid.

In a particularly advantageous embodiment of the second aspect of the present invention, the first climbing aid can be biased into the active position by means of an elastic element over its entire path of movement and can be locked in the passive position. If the first climbing aid is biased into the active position over its entire trajectory and can also be locked in the passive position, it is sufficient to move the climbing aid from the locked, passive position to the active position by releasing this lock in order to achieve an adjustment. The first climbing aid no longer has to be guided over its entire movement path or part of this movement path, but it can be sufficient to release a locking mechanism, which can be present as a latching or hook mechanism, for example. All locking options are conceivable here. In particular, the Lock can be released, for example, by pressing on the climbing aid with a ski pole. By pretensioning the first climbing aid into the active position, the first climbing aid can move automatically into the active position after the lock has been released. The adjustment of the first climbing aid can be done semi-automatically, so to speak, and operation of the climbing aid can be further simplified.

The elastic element can provide a spring force both for the first climbing aid and for the second climbing aid. In particular, the elastic element can transmit the spring force for the first climbing aid directly by being arranged on the first climbing aid, and indirectly transmitting the spring force for the second climbing aid by being arranged on the first climbing aid and the spring force being applied to the first climbing aid second climbing aid transfers. The second climbing aid can, for example, be pretensioned into the active position by the elastic element. In addition, the second climbing aid can assume a stable position in the standby position, in particular due to the interaction of a surface of the second climbing aid with a surface of the binding body or the like and the elastic element. The exact position of the ready position can be set by means of an angle of the surface of the binding body.

Furthermore, the first climbing aid can be locked in the passive position by means of the second climbing aid. In this way, both climbing aids can advantageously be locked in the passive position by only one locking mechanism.

In a further embodiment, the first climbing aid can be pretensioned by means of an elastic element and can be designed to pass a dead center when the first climbing aid is adjusted from the passive position to the active position. Such an arrangement with a dead center passage of the pretensioned first climbing aid is special easy to handle. The first climbing aid is pretensioned by means of the elastic element, either in its passive position or in its active position. If, when moving between the passive position and the active position, the first climbing aid exceeds the dead point at which the elastic element is most strongly compressed, it "snaps" into the active position. Conversely, if the first climbing aid exceeds dead center when moving between the active position and the passive position, it "snaps" into the passive position. With this embodiment, user convenience can be further improved by this extremely intuitive operation.

First embodiment

The Figures 1 to 6 show a heel unit 10 according to a first embodiment of the present invention. The heel unit 10 comprises a binding body 12 and a climbing aid 20 which, in particular, can be pivotably mounted on the binding body 12 on an axis 22. The binding body 12 is suitable for holding a heel section of a touring shoe (not shown) in a downhill position of the heel unit 10 and for releasing the heel section of the touring shoe in a touring position of the heel unit 10 so that the touring shoe can lift off the heel unit 10. The climbing aid 20 is between an active position, which in the Figures 4 to 6 is shown, and a passive position adjustable, which in the Figures 1 and 2 is shown. In the touring position of the heel unit 10, the climbing aid 20 supports the heel section of the touring shoe in its active position at a predetermined height above a gliding board level. The climbing aid 20 is biased into the active position over its entire path of movement by means of an elastic element (not shown). The elastic element can be implemented, for example, by a leg spring which is arranged on the axle 22 and transmits a spring force to the binding body 12 and to the climbing aid 20. However, other types of springs or other types of elastic elements are also conceivable in order to pretension the climbing aid 20 into the active position. In addition, the climbing aid 20 can be locked in the passive position, for example by means of locking projections or the like.

In the embodiment shown, the climbing aid 20 can be a first climbing aid 20 and a second climbing aid 30 can also be provided, which is also adjustable between an active position and a passive position, with the second climbing aid 30 in its touring position of the heel unit 10 active position supports the heel section of the touring shoe at a predetermined height which is higher than the predetermined height of the first climbing aid 20. The second climbing aid 30 can be pivotably mounted on an axis 32 on the first climbing aid 20.

In the individual figures, a transition of the climbing aid 20 from the passive position to the active position is shown.

In the Figures 1 and 2 are a perspective view and a side view of the heel unit 10 according to the first embodiment with the first climbing aid 20 in the passive position and the second climbing aid 30 in the passive position. The first climbing aid 20 can be locked in the passive position by means of the second climbing aid 30. A locking can take place, for example, by a locking projection 14 provided on the binding body 12 and a projection 36 provided on the second climbing aid 30, which engages with the locking projection 14. Alternatively, it is possible that a projection provided on the first climbing aid 20 engages in a latching projection provided on the binding body 12 in order to lock the first climbing aid 20 in the passive position. In addition, several locking projections and projections formed complementarily thereto may be provided in order to lock the first climbing aid 20 and / or the second climbing aid 30 in the passive position. In the first embodiment, the locking, which takes place via the second climbing aid 30 mounted on the first climbing aid 20, can be released by pressing either on the unlocking extension 38 on the second climbing aid 30 or on the unlocking surface 40 on the second climbing aid 30. This can be done by hand or with a ski pole, for example. In both possibilities, the engagement between the projection 36 and the locking projection 14 and thus the locking of the first climbing aid 20 and the second climbing aid 30 can be released.

In Figure 3 a position of the climbing aids 20, 30 shortly after a release of the engagement between the projection 36 and the locking projection 14 is shown. Since the first climbing aid 20 is pretensioned into the active position over its entire path of movement, it moves into the active position after the lock has been released. This is in Figure 4 shown. In the touring position of the heel unit 10 in the active position of the first climbing aid 20, the heel section of the touring shoe can be supported on a support surface 24 of the first climbing aid 20 at the predetermined height above the plane of the gliding board.

The elastic element can advantageously provide a spring force both for the first climbing aid 20 and for the second climbing aid 30. In the embodiment described, this takes place in that the second climbing aid 30 is mounted on the first climbing aid 20, on which the elastic element in turn acts in the form of the leg spring (not shown). As in Figure 4 As can be seen, a fitting surface 42 of the second climbing aid 30 is pressed by this spring force against an opposing fitting surface 16 of the binding body 12 and the second climbing aid 30 is held spring-loaded in a ready position in which it protrudes upward from the binding body 12. As a result, an operator of the second climbing aid 30 or an adjustment of the second climbing aid 30 in its active position can be made much easier. The exact position of the ready position of the second climbing aid can be adjusted by means of an angle of the mating surface 16 of the binding body 12.

In order to adjust the second climbing aid 30 into the active position, it only has to be moved from the standby position into the active position again, for example by hand or a ski pole. As soon as an edge between the mating surface 40 and the unlocking surface 42, which can slide over the mating surface 16 of the binding body 12 during this adjustment, exceeds a certain point, the second climbing aid 30 can also be biased into the active position by the spring force of the elastic element. This position is in Figure 5 as a side view of the heel unit 10 and in Figure 6 shown as a sectional view of the heel unit 10. The unlocking surface 40 of the second climbing aid 30 can be pressed against the fitting surface 16 of the binding body 12 in order to keep the second climbing aid 30 in the active position by the spring force of the elastic element. In the touring position of the heel unit 10 in the active position of the second climbing aid 30, the heel section of the touring shoe can be supported on a support surface 34 of the second climbing aid 30 at the predetermined height above the gliding board level, which is higher than the predetermined height of the first climbing aid 20.

Second embodiment

The Figures 7 to 10 show a heel unit 110 according to a second embodiment of the present invention. The heel unit 110 comprises a binding body 112, a first climbing aid 120 and optionally a second climbing aid 130. The binding body 112 is suitable for holding a heel section of a touring boot (not shown) in a downhill position of the heel unit 110 and the heel section of the touring boot in a touring position of the heel unit 110 to release so that the touring shoe can lift off the heel unit 110. The first climbing aid 120 is between an active position, which in the Figures 9 and 10 is shown, and a passive position adjustable, which in the Figures 7 and 8 is shown. In the touring position of the heel unit 110, the first climbing aid 120 supports the heel section of the touring shoe in its active position at a predetermined height above a gliding board level. The second climbing aid 130 is between an active position, which is shown in FIG Figure 10 is shown, and a passive position adjustable, which in the Figures 7 and 8 is shown. In the touring position of the heel unit 110, the second climbing aid 130 in its active position supports the heel section of the touring boot at a predetermined height above a gliding board level which is higher than the predetermined height of the first climbing aid 120.

The first climbing aid 120 is biased into the active position over its entire path of movement by means of an elastic element (not shown). The elastic element can be implemented, for example, by a leg spring, a compression spring or a tension spring. In addition, the first climbing aid 120 can be locked in the passive position, for example by means of locking projections or the like. A locking can take place, for example, by a locking projection 114 provided on the binding body 112 and a driver projection 126 provided on the first climbing aid 120, which engages with the locking projection 114. A plurality of latching projections and projections designed to be complementary thereto can also be provided in order to lock the first climbing aid 120 and / or the second climbing aid 130 in the passive position.

The first climbing aid 120 can also be configured to transfer the second climbing aid 130 into a standby position when the first climbing aid 120 is adjusted from the passive position to the active position, which is located between the passive position and the active position of the second climbing aid 130 . In the standby position of the second climbing aid 130, which is shown in Figure 9 is shown, the second climbing aid 130 advantageously protrude upwards from the binding body 112 and is thus easier to grip or operate, while in the passive position it can advantageously lie close to the binding body 112. In this way, operation of the second climbing aid 130 is simplified. In addition, a shortened path has to be overcome for an adjustment of the second climbing aid 130 into the active position. Especially in the Figures 8 and 9 it can be seen that the first climbing aid 120 via the driver projection 126, which rests on a surface of the second climbing aid 130, can take it with it when the first climbing aid 120 is adjusted from the passive position into the active position into the standby position.

The first climbing aid 120 can be composed of a first part 120a and a second part 120b. The first part 120a of the first climbing aid 120 can be mounted on the heel unit 110, in particular on the binding body 112, so that it can slide linearly in longitudinal grooves 116 formed in the binding body 112. The second part 120b of the first climbing aid 120 can be pivotably mounted on an axis 122 formed on the first part 120a of the first climbing aid 120. Thus, the first climbing aid 120 can be adjusted from the passive position to the active position by releasing the locking of the first climbing aid 120, the first part 120a of the first climbing aid 120 sliding forward in the longitudinal direction of the ski and the second part 120b of the first climbing aid 120 pivots forward about the axis 122 and can take the second climbing aid 130 with it into the standby position. This position is in Figure 9 shown.

An axis 132 of the second climbing aid 130 can be mounted in grooves 118 formed on both sides of the binding body 112 so as to be longitudinally displaceable in the longitudinal direction of the ski and can also be connected to the first climbing aid 120 via straps 150 formed on both sides.

Fourth embodiment

The Figures 15 to 18 show a heel unit 310 according to a fourth embodiment of the present invention. The heel unit 310 comprises a binding body 312, a first climbing aid 320 and a second climbing aid 330. The binding body 312 is suitable for holding a heel section of a touring boot (not shown) in a downhill position of the heel unit 310 and for releasing the heel section of the touring boot when the heel unit 310 is in a touring position so that the touring shoe can lift off the heel unit 310. The first climbing aid 320 is between a passive position, which in the Figures 15 and 16 is shown, and an active position adjustable, which in Figure 18 is shown. In the touring position of the heel unit 310, the first climbing aid 320 in its active position supports the heel section of the touring shoe on a support surface 324 at a predetermined height above a gliding board level. The second climbing aid 330 is between a passive one Position, which in the Figures 15 and 16 is shown, and adjustable to an active position, not shown. In the touring position of the heel unit 310, the second climbing aid 330 supports the heel section of the touring boot in its active position on a support surface 334 at a predetermined height above a gliding board level which is higher than the predetermined height of the first climbing aid 320.

In the embodiment shown, as in the first embodiment, the first climbing aid 320 can be pivotably mounted on the binding body 312 about an axis 322 and the second climbing aid 30 can be pivotably mounted on an axis 332 on the first climbing aid 320.

The first climbing aid 320 is also designed to transfer the second climbing aid 330 into a standby position when the first climbing aid 320 is adjusted from the passive position to the active position, which is located between the passive position and the active position of the second climbing aid 330.

In the standby position of the second climbing aid 330, which is shown in Figure 18 As shown, the second climbing aid 330 can advantageously protrude upwards from the binding body 312 and is thus easier to grip or operate, while in the passive position it can advantageously lie close to the binding body 312. In this way, operation of the second climbing aid 330 is simplified. In addition, a shortened path has to be overcome for an adjustment of the second climbing aid 330 into the active position.

Furthermore, in the fourth embodiment of the present invention, the first climbing aid 320 is pretensioned by means of an elastic element (not shown) such as a spring or the like. In particular, it is within a certain section of a movement pad of the first climbing aid 320 between the active position and the passive position biased active position and, after passing dead center, it is biased into the passive position in the remaining portion of the motion pad.

In the Figures 16 to 18 shows a transition of the first climbing aid 320 from the passive position over the dead center into the active position and a transition of the second climbing aid 230 from the passive position to the standby position.

In Figure 16 Both the first climbing aid 320 and the second climbing aid 330 are shown in the passive position. The first climbing aid 320 is biased into the passive position. By pressing on the first climbing aid 320, for example on the support surface 324, the first climbing aid 320 can be moved about the axis 322 against the pretensioning force in the direction of the active position.

In Figure 17 the dead center passage of the first climbing aid 320 is shown. In the position shown, the elastic element which acts on the first climbing aid 320 with a spring force is most strongly compressed and gradually relaxes again when the first climbing aid 320 moves further about the axis 322 in the direction of the active position beyond this point. The first climbing aid 320 is thus initially pretensioned into the passive position, preloaded into the active position after the dead center has been exceeded and, due to the pretensioning force, automatically moves further into the in Figure 18 active position shown. At the same time, the second climbing aid 330 is transferred to the standby position, as in FIG Figures 17 and 18 is shown.

In the in Figure 18 In the active position shown, a surface 325 of the first climbing aid 320, which is provided on a leg of the first climbing aid 320 facing the axis 322, comes into contact with a mating surface 315 provided on the binding body 312.
