Description

[0001] The present invention relates to a heel unit for a ski-ski binding, in particular a touring binding, comprising a base for attachment to a ski-ski board, a binding body which is directly or indirectly connected to the base and which is suitable for holding a heel section of a boot in a downhill position of the heel unit and for releasing the heel section of the boot in a touring position of the heel unit so that the 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 a sole section of the boot by means of a first support section at a first predetermined height above a ski-ski board plane, 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 sole section of the shoe by means of a second support section at a second predetermined height above the sliding board plane, wherein the sole section is located closer to the sliding board plane at the first predetermined height than at the second predetermined height, and a braking arrangement comprising a pedal having a tread surface for the sole section of the shoe on its side facing away from the sliding board, and at least one braking arm mounted at the base and on the pedal, wherein the braking arrangement is adjustable between a braking position and a sliding position.

[0002] The heel units discussed in the present disclosure are, in particular, heel units for touring ski bindings, the binding body of which is to be attached to a touring ski. However, splitboards (snowboards that can be divided longitudinally, the halves of which can be used like touring skis) or similar devices are equally suitable as gliding boards to which a heel unit according to the invention is to be attached, so that the invention also relates to heel units for bindings of such gliding boards, although the following reference is made, without limiting the subject matter of the invention, mainly to touring ski bindings.

[0003] Such heel units are known in the prior art. For example, DE 10 2012 208 915 A1 and EP 2 638 937 A1 disclose such a heel unit with two climbing aids.

[0004] A climbing aid is used in ski mountaineering to compensate for changes in terrain gradient while walking. Steep terrain can be compensated for by engaging the climbing aid, thereby increasing the contact or support height for the heel section of a touring boot. Conventional touring bindings often feature one or two climbing aids, so that in addition to a so-called "zero position" (where no climbing aid is engaged and the heel section of the touring boot rests directly on a ski, a base, or the brake pedal of the heel unit), one or two further support heights can be set by the user switching the climbing aid from a passive to an active position.

[0005] Often, the climbing aid is pivotally mounted on the binding body of the heel unit and must be manually or with a ski pole pivoted from the passive to the active position by the user. Especially in adverse conditions, which are common in ski mountaineering due to cold, wind, ice, and snow, such an adjustment can be quite difficult, particularly since climbing aids are increasingly made of smaller and more difficult-to-grip components to save weight. If two climbing aids are provided, the second climbing aid is often also pivotally mounted on the binding body, preferably on the same axis as the first. The problems mentioned above therefore also occur when adjusting the second climbing aid from the passive to the active position.

[0006] In the case of DE 10 2012 208 915 A1, the braking arrangement is pre-tensioned into a braking position by a spring and can be locked in a sliding position by a first climbing aid. To release this lock, the first climbing aid must be manually moved from an active to a passive position to disengage the first climbing aid and a pedal of the braking arrangement. Due to the strong pre-tension of the spring, which is necessary for a sufficiently high braking effect of the braking arrangement, there is a considerable risk of injury when moving the first climbing aid from the active to the passive position, as the pedal of the braking arrangement springs upwards when the engagement between the climbing aid and the pedal is released and can strike the user's hand. Releasing the engagement with a ski pole, on the other hand, is more cumbersome and requires a certain amount of force.

[0007] Furthermore, heel units with other types of climbing aids are also known, but these are either difficult to use or have complex, relatively heavy and / or costly arrangements, for example pneumatically, hydraulically and / or electronically operating.

[0008] Against this background, an objective of the present invention was to provide a heel unit for a touring binding that enables simple and safe operation of one or, if applicable, several climbing aids with a reduced risk of injury. Furthermore, the heel unit should optionally prevent incorrect operation, be as simple in design as possible, be lightweight, and be comparatively inexpensive to manufacture.

[0009] According to a first aspect of the present invention, the problem formulated above is solved by a heel unit for a ski-mount binding, in particular a touring binding, comprising a base for attachment to a ski-mount, a binding body which is directly or indirectly connected to the base and which is suitable for holding a heel section of a boot in a downhill position of the heel unit and for releasing the heel section of the boot in a touring position of the heel unit so that the 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 a sole section of the boot by means of a first support section at a first predetermined height above a ski-mount plane, 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 sole section of the shoe by means of a second support section at a second predetermined height above the sliding board plane, wherein the sole section is located closer to the sliding board plane at the first predetermined height than at the second predetermined height, and a braking arrangement comprising a pedal which has a tread surface for the sole section of the shoe on its side facing away from the sliding board, and at least one braking arm which is mounted at the base and on the pedal, wherein the braking arrangement is adjustable between a braking position and a sliding position and wherein the braking arrangement is elastically pre-tensioned in the braking position, wherein the second climbing aid interacts with the braking arrangement in such a way thatthat an adjustment of the second climbing aid from the active position to the passive position causes an adjustment of the brake arrangement from the sliding position to the braking position and / or an adjustment of the second climbing aid from the passive position to the active position causes an adjustment of the brake arrangement from the braking position to the sliding position.

[0010] According to an important feature of the present invention, the second climbing aid thus serves as an actuating element for adjusting the brake assembly between the sliding position and the braking position. In other words, by actuating / operating the second climbing aid, the brake assembly can be moved from the sliding position to the braking position or vice versa. Since the second climbing aid typically protrudes significantly from the heel unit and is therefore easier to reach and grip, such a design of the heel unit ensures simple and safe operation and minimizes the risk of incorrect use or misuse.

[0011] In connection with the present invention, the "braking position" of the brake arrangement can particularly mean that the brake arm or arms project in a horizontal lateral direction (essentially parallel to the plane of the sliding board) of the sliding board and that an end or braking section of the brake arm or arms projects downwards in a vertical direction past the sliding board in order to engage with the surface, in particular snow or ice. The "gliding position" refers in particular to the fact that the brake arm or arms are raised in a vertical direction (essentially perpendicular to the plane of the sliding board) to a level above a sliding surface of the sliding board, so that the brake arm can no longer engage with the surface.Specifically, it is intended that two brake arms are provided, one on the right side and one on the left side of the heel unit, running lengthwise along the heel unit (which may also be referred to as the direction of travel). However, it is also possible that only one brake arm is provided. The "sliding board plane" is defined as a plane essentially parallel to a running surface of the sliding board, which essentially coincides with the sliding board surface on which the heel unit can be mounted.

[0012] In a preferred embodiment of the present invention, the binding body can be rotatable about an axis of rotation orthogonal to the ski board plane in order to adjust the heel unit between the downhill position and the touring position. This axis of rotation can also be referred to in the present disclosure as the vertical axis. By rotating the binding body about such an axis of rotation, the heel unit can be easily and particularly user-friendly adjusted between the downhill position and the touring position.

[0013] The heel unit can further comprise coupling pins that run essentially parallel to each other and extend from the binding body in a plane essentially parallel to the glide board plane. These pins are designed to engage recesses provided in the heel section of a boot when the heel unit is in the downhill position, thereby securing the heel section of the boot. Such coupling pins, which may also be made of a metal material, ensure a stable and reliable connection between the heel unit and the boot when the heel unit is in the downhill position. This connection is achieved by the coupling pins engaging in the recess provided in the boot, which may be reinforced, in particular, by a metallic insert.

[0014] In a further preferred embodiment of the present invention, the first climbing aid can be pivotally mounted about a pivot axis on the heel unit, in particular on the binding body. Alternatively, a pivotable mounting of the first climbing aid at the base of the heel unit is also conceivable. A pivotable mounting of the first climbing aid on any component whatsoever enables easy operation of the climbing aid by a simple rotational movement of the same about the pivot axis.

[0015] Similarly, the second climbing aid can be pivotally mounted on the heel unit, particularly on the binding body, around a pivot axis. Alternatively, a pivotable mounting of the first climbing aid at the base of the heel unit or on the first climbing aid itself is also conceivable. Again, a pivotable mounting of the second climbing aid in this case allows for easy operation of the climbing aid by simply rotating it around the pivot axis.

[0016] In particular, it is intended that the first and second climbing aids share a common pivot axis. By providing only one pivot axis for both climbing aids, ease of use is ensured, and the heel unit, with its simpler design and fewer components, becomes less expensive to manufacture and lighter overall. Both climbing aids can be pre-tensioned into their active and passive positions, respectively, via a dead-center mechanism, or pre-tensioned into one of the active and passive positions and releasably locked in the untensioned position.

[0017] Furthermore, the brake assembly can advantageously be configured such that, when the brake assembly is moved from the sliding position to the braking position, particularly by the elastic preload of the brake assembly, the at least one brake arm performs a movement with both a horizontal and a vertical component. Movement of the brake arm in both the horizontal and vertical directions means that the movement of the brake arm comprises a horizontal component and a vertical component. That is, it also implies a linear direction that is inclined relative to the sliding board. Such movement is performed, in particular, by a lower, exposed end of the brake arm, which is configured to engage with a surface beneath the sliding board in the braking position and which is hereinafter referred to as the braking section.

[0018] It has also proven particularly advantageous if the first climbing aid is coupled to the brake arrangement in such a way that an adjustment of the first climbing aid from the active position to the passive position causes an adjustment of the brake arrangement from the sliding position to the braking position, and / or an adjustment of the first climbing aid from the passive position to the active position causes an adjustment of the brake arrangement from the braking position to the sliding position, wherein the second climbing aid is configured to act on the first climbing aid when it is adjusted from the active position to the passive position, such that the first climbing aid is also adjusted from the active position to the passive position, thus adjusting the brake arrangement from the sliding position to the braking position, and / or wherein the second climbing aid is configured to act on the first climbing aid when it is adjusted from the passive position to the active position,that this is also moved from the passive position to the active position, thus moving the brake assembly from the braking position to the sliding position. Consequently, the second climbing aid interacts with the brake assembly in such a way that moving the second climbing aid from the active position to the passive position moves the brake assembly from the sliding position to the braking position, and / or moving the second climbing aid from the passive position to the active position moves the brake assembly from the braking position to the sliding position. However, this can preferably be achieved using or interposing the first climbing aid, which can be operationally positioned between the second climbing aid and the brake assembly. Thus, according to this embodiment, there is no direct interaction between the second climbing aid and the brake assembly, and unlocking the brake assembly is not possible.In other words, adjusting the brake arrangement from the sliding position to the braking position can be done without an increased risk of injury, since the brake arrangement is locked by the first climbing aid but can be unlocked by means of the second climbing aid.

[0019] For this purpose, the second climbing aid can include at least one drive lug configured to engage a first contact section and / or the first support section of the first climbing aid when the second climbing aid is moved from the passive position to the active position, thereby also moving the first climbing aid from the passive position to the active position, and / or to engage a second contact section of the first climbing aid when the second climbing aid is moved from the active position to the passive position, thereby also moving the first climbing aid from the active position to the passive position. In particular, the second climbing aid, and optionally also the first climbing aid, can include two arms that can extend to the left and right sides of the binding body, and at the end sections of which the climbing aid can be mounted on the binding body by means of the pivot axis.The drive lug can be located shortly before the end section on one or both of these arms. In this way, direct contact between the second drive lug, acting as an actuating element for adjusting the brake assembly, and the first drive lug, acting as a locking element for locking the brake assembly, enables simple and particularly reliable operation of the brake assembly by the drive lugs. In a preferred embodiment of the present invention, the drive lug of the second drive lug can create a dead center for the second drive lug.

[0020] In particular, the first contact section and the second contact section of the first climbing aid can be arranged on opposite sides with respect to the pivot axis of the first climbing aid. Accordingly, when the second climbing aid is rotated, e.g., clockwise from one side of the heel unit, and the second climbing aid is thereby moved from the passive to the active position, the drive lug of the second climbing aid can contact the first contact section of the first climbing aid and thus also move the first climbing aid from the passive to the active position. Conversely, when the second climbing aid is rotated, e.g.,Viewed counterclockwise from one side of the heel unit, the second climbing aid is moved from its active to its passive position. This causes the drive lug of the second climbing aid to contact the second contact section of the first climbing aid, thus also moving the first climbing aid from its active to its passive position. In this way, the braking mechanism can be adjusted between the braking position and the sliding position in a particularly simple manner using the second climbing aid.

[0021] In this embodiment, the first climbing aid can advantageously be configured to move the second climbing aid into a ready position when the first climbing aid is moved from the passive position to the active position. This ready position is located between the passive and active positions of the second climbing aid. If, when the first climbing aid is moved from the passive to the active position, the second climbing aid moves along with it for part of its path of movement—that is, if it moves the second climbing aid into a ready position that is a kind of intermediate position between the active and passive positions—then a shorter path needs to be traversed to move the second climbing aid into the active position. Furthermore, in the ready position, the second climbing aid can protrude from the heel unit or binding body, making it easier to grip.It is easy to 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 by moving it into the ready position when the first climbing aid is adjusted. If the second climbing aid, which is easier to operate in the ready position, is then moved from the ready position back to its passive position, the first climbing aid can be moved towards the passive position by means of the second climbing aid, and thus the braking mechanism can also be moved from the sliding position to the braking position by means of the second climbing aid via the first climbing aid.In other words, the brake arrangement can be adjusted by the second climbing aid, but not by a direct interaction between the second climbing aid and the brake arrangement, but by using the first climbing aid, which interacts with the brake arrangement and which can be adjusted by the second climbing aid.

[0022] Furthermore, the first climbing aid can be configured to block movement of the at least one brake arm in a direction substantially parallel to the sliding plane when in its active position, such that the brake arrangement is locked in the sliding position. This direction, substantially parallel to the sliding plane, is also referred to in the present disclosure as the horizontal direction. That is, the brake arrangement is locked in the sliding position when the first climbing aid is in the active position. The sliding position of the brake arrangement can then also be referred to as the walking position. Due to the design of the brake arrangement, blocking the movement of the brake arm in the horizontal direction also prevents movement of the brake arm in the vertical direction.Since a force component acting in a horizontal direction of the elastic preload of the brake arrangement is significantly smaller than a force component acting in a vertical direction of the elastic preload of the brake arrangement, locking the brake arrangement in the sliding position is also possible in a simpler way than if a movement of the brake arm in the vertical direction were blocked.

[0023] For this purpose, the first climbing aid can preferably have a contact surface which, when the brake assembly is in the sliding position, is designed to contact a section of the brake arm facing the contact surface of the first climbing aid when the first climbing aid is in its active position. In particular, a stop acting in a horizontal direction between the contact surface of the first climbing aid and the section of the brake arm facing this contact surface is envisaged. Direct contact between the first climbing aid and the brake arm can ensure better power transmission, fewer components, lower weight, and generally a less complex design of the heel unit.

[0024] In particular, the first climbing aid can comprise at least one retaining projection, which is arranged on a side of the first climbing aid facing the sliding board in the active position of the first climbing aid and provides the contact surface for the at least one brake arm. In particular, such a retaining projection can be provided on a side of the first climbing aid opposite the first support section of the climbing aid, which provides a tread surface for the heel sole section of the shoe for support at the first height. Furthermore, it is specifically envisaged that two such retaining projections are provided, each on the outside of the climbing aid in a lateral direction orthogonal to a longitudinal direction or direction of travel of the heel unit, in order to prevent outward movement of two brake arms.

[0025] According to a second aspect of the present invention, the problem formulated above is solved by a sliding board binding, in particular a touring binding, comprising the heel unit according to the first aspect of the present invention. In particular, a touring binding is intended in connection with the present invention. Such a sliding board or touring binding offers the same or similar advantages as the heel unit according to the first aspect of the present invention.

[0026] The invention is explained in more detail below with reference to a preferred embodiment and the accompanying drawings. Specifically, the drawings show: Fig. 1 a perspective view of a heel unit according to the preferred embodiment of the present invention in a touring position with a brake arrangement in a sliding position, Fig. 2 a side view of the heel unit Fig. 1, Fig. 3 an enlarged view of the in Fig. 2.

[0027] With reference to Fig. 1 is a heel unit according to the preferred embodiment of the present invention, generally characterized by reference numeral 10. Fig. Figure 1 shows a perspective view of the heel unit 10 in a touring position.

[0028] The heel unit 10 comprises a base 12 for attachment to a sliding board. A sliding board plane E is defined by an underside of the base 12. The base 12 can be attached by means of mounting holes 14. The heel unit 10 further comprises a binding body 20, which is connected directly or indirectly to the base 12. In the present embodiment, a carriage 16 can be guided on the base 12 so as to be slidable in the longitudinal direction of travel of the heel unit 10, and the binding body 20 can be coupled to the carriage 16 and thus indirectly connected to the base 12.

[0029] The binding body 20 is configured in a downhill position of the heel unit 10 to hold a heel section of a boot, and in a touring position of the heel unit 10 to release the heel section of the boot so that the boot can lift off the heel unit 10.

[0030] It should be noted that the heel unit 10 is shown in the touring position in all figures of this disclosure. In the present embodiment, the heel unit 10 can be adjusted between the downhill position and the touring position by rotating the binding body 20 about a rotation axis V orthogonal to the skid plate plane E, which is also referred to as the vertical axis or vertical axis V. The boot can be held in place by coupling pins 22 that are substantially parallel to each other, project from the binding body 20, and extend in a plane substantially parallel to the skid plate plane E.

[0031] Since all figures in this disclosure are shown in the touring position, the coupling pins 22 in the figures point rearward in one direction of travel. If, in the present embodiment, the binding body 20 is rotated 180° about the vertical axis V, the coupling pins 22 point forward in the direction of travel and can engage recesses provided in a heel section of a shoe to hold the heel section of the shoe in place, thereby realizing the descent position of the heel unit 10. With reference, for example, to Fig. 2. A spring element 24 can be provided which can cause a preload of the coupling pins 22 towards each other in order to provide a frontal release for the heel unit 10. In addition, a spring element (not shown) can be provided for a preload of the rotational movement of the binding body 20 about the axis of rotation V in order to provide a lateral release for the heel unit 10.

[0032] The heel unit 10 further comprises a first climbing aid 30, which is adjustable between an active position and a passive position, and a second climbing aid 40, which is also adjustable between an active position and a passive position. In the touring position of the heel unit 10, the first climbing aid 30, in its active position, supports a sole section of the shoe by means of a first support section 32 at a first predetermined height above a sliding board plane, and the second climbing aid 40, in its active position, supports the sole section of the shoe by means of a second support section 42 at a second predetermined height above the sliding board plane, wherein the sole section is located closer to the sliding board plane at the first predetermined height than at the second predetermined height.In the preferred embodiment, the first climbing aid 30 and the second climbing aid 40 can be pivotally mounted on the binding body 20 about a common pivot axis S. In the preferred embodiment of the invention, both the first climbing aid 30 and the second climbing aid 40 can each comprise two arms extending to the left and right sides of the binding body 20, and the climbing aids 30 and 40 can be mounted on the binding body 20 at their end sections by means of the pivot axis S. Both climbing aids 30 and 40 can, in particular, be pre-tensioned into their active and passive positions, respectively, by means of a dead-center pass, or be pre-tensioned into either the active or the passive position and releasably locked in the respective unpre-tensioned position.

[0033] Furthermore, the heel unit 10 includes a brake assembly 50, which is adjustable between a braking position and a sliding position, wherein the brake assembly 50 is elastically pre-tensioned in the braking position. In the Fig. Figures 1 to 5 show the brake assembly in the sliding position. In this context, the present disclosure may also refer to the brake assembly 50 being locked in the sliding position or unlocked in the braking position. The brake assembly 50 comprises a pedal 52, which has a tread surface 54 for the sole section of the shoe on its side facing away from the sliding board, and at least one, or in the present embodiment two, brake arms 60, which are mounted on the base 12 and on the pedal 52 and each have a brake section 62 at the end of the arm, which is configured to engage with a surface in the departure position of the heel unit 10 and in the braking position of the brake assembly 50, for example, when no shoe is coupled to the heel unit 10 to brake the sliding board due to a fall and the associated release.

[0034] The second climbing aid 40 interacts with the brake assembly 50 in such a way that an adjustment of the second climbing aid 40 from the active position to the passive position causes an adjustment of the brake assembly 50 from the sliding position to the braking position and / or an adjustment of the second climbing aid 40 from the passive position to the active position causes an adjustment of the brake assembly 50 from the braking position to the sliding position. This will be explained below with reference to the Fig. 2 to 5 explained in more detail.

[0035] Fig. Figure 2 shows a side view of the heel unit 10. Fig. 1 and Fig. Figure 3 shows an enlarged view of the in Fig. 2. Detail marked A, in which the interaction between the first climbing aid 30 and the second climbing aid 40 is more clearly recognizable. Fig. Figure 4 shows a top view of the heel unit 10. Fig. 1 and Fig. 5 shows a section view along line BB in Fig. 4.

[0036] With reference to the Fig. 1 and Fig. Figure 5 shows that in the preferred embodiment of the invention, the first climbing aid 30 can be coupled to the brake arrangement 50 in such a way that an adjustment of the first climbing aid 30 from the active position to the passive position causes an adjustment of the brake arrangement 50 from the sliding position to the braking position, and an adjustment of the first climbing aid 30 from the passive position to the active position causes an adjustment of the brake arrangement 50 from the braking position to the sliding position. Fig. Figure 5 shows that the first climbing aid 30 can be coupled to the brake assembly 50 by means of two projections or retaining projections 38 arranged on the outside of the first climbing aid 30 in a lateral direction of the heel unit 10, each having an inwardly facing contact surface 39, wherein the two contact surfaces 39 interact with contact sections 64 provided on the brake arms 60 to lock the brake assembly 60 in the sliding position. This interaction is described below with further reference to Fig. 5 explained in more detail.

[0037] Furthermore, in this case, the second climbing aid 50, when moved from the active position to the passive position, can in turn act on the first climbing aid 30 in such a way that the latter is also moved from the active position to the passive position, thus changing the brake assembly 50 from the sliding position to the braking position. Likewise, when moved from the passive position to the active position, the second climbing aid 50 can act on the first climbing aid 30 in such a way that the latter is also moved from the passive position to the active position, thus changing the brake assembly 50 from the braking position to the sliding position. This can be described in the present embodiment with reference to Fig. 3 by the fact that the second climbing aid 40 can include at least one drive lug 44 which, when the second climbing aid 40 is adjusted from the passive position to the active position, abuts a first contact section 34 of the first climbing aid 30 (see Fig. 13, in which the brake assembly 50 is shown in the braking position), in order to also move the first climbing aid 30 from the passive position to the active position. Alternatively or additionally, a section on a side opposite the second support section 42 of the second climbing aid 40 can also contact the first support section 32 of the first climbing aid 30 in order to move the first climbing aid 30 from the passive position to the active position. When moving the second climbing aid 40 from the active position to the passive position, the drive lug 44 can abut a second contact section 36 of the first climbing aid 30 (see Figure 13). Fig. 3, Fig. 8) to also adjust the first climbing aid 30 from the active position to the passive position. In particular, the second climbing aid 40 and the first climbing aid 30 can comprise two arms extending to the left and right of the binding body 20, and at the end sections of which the climbing aids 30, 40 can be mounted on the binding body 20 by means of the pivot axis S. The drive lug 44 can, as in Fig. As can be seen in Figure 3, the drive lug 44 is provided shortly before the end section on one or both of these arms. In the present embodiment, the drive lug 44 is provided on both arms of the second climbing aid 44. It can also be seen that the first contact section 34 of the first climbing aid 30 and the second contact section 36 of the first climbing aid 30 can be arranged on opposite sides with respect to the pivot axis S of the first climbing aid 30. Accordingly, when the second climbing aid 40 is rotated, e.g., in the Fig. 3, Fig. 8 and Fig. 13 clockwise, and an associated adjustment of the second climbing aid 40 from the passive position to the active position, the drive nose 44 of the second climbing aid contacts the first contact section 34 of the first climbing aid 30 (see Fig. 13) and thus also transfer the first climbing aid 30 from the passive position to the active position. Alternatively or additionally, the section on the side opposite the second support section 42 of the second climbing aid 40 can also contact the first support section 32 of the first climbing aid 30 to transfer the first climbing aid 30 from the passive position to the active position. Conversely, if the second climbing aid 40 is rotated, e.g., into the Fig. 3, Fig. 8 and Fig. 13 counterclockwise, and an associated adjustment of the second climbing aid 40 from the active position to the passive position, the drive lug 44 of the second climbing aid 40 contacts the second contact section 36 of the first climbing aid 30 (see Fig. 3, Fig. 8) and thus also transfer the first climbing aid 30 from the active position to the passive position. In the present embodiment, the drive lug 44 can also realize a dead-point passage for the second climbing aid 40 as already described above.

[0038] Returning to Fig. 2 In a preferred embodiment of the present invention, when the first climbing aid 30 is adjusted from the passive position to the active position, the second climbing aid 40 can be moved into a ready position, which is located between the passive position and the active position of the second climbing aid 40 and which is located in the Fig. 1 to 5 (best seen in Fig. 2) is shown.

[0039] Again, with reference to Fig. 5 can the first climbing aid 30 in its active position, which is in the Fig. As shown in Figures 1 to 5, the braking arrangement 50 blocks the movement of at least one brake arm 60, and in particular both brake arms 60, in a direction substantially parallel to the sliding plane E, such that the braking arrangement 50 is locked in the sliding position. Due to the design of the braking arrangement 50, blocking the movement of the brake arm 60 in the horizontal direction also prevents movement of the brake arm in the vertical direction. This locking function of the first climbing aid 30 can be realized, as already mentioned above, by a retaining projection 38 provided on at least one of the first climbing aid 30, which is arranged on a side of the first climbing aid 30 facing the sliding board in the active position of the first climbing aid 30 and provides the contact surface 39 for the at least one brake arm 60.In particular, such a retaining projection 38 can be provided on the side of the first climbing aid 30 opposite the first support section 32 of the climbing aid 30, which provides a tread surface for the heel sole section of the shoe for support at the first height. Furthermore, it is specifically envisaged that two such retaining projections 38 are provided, each on the outside of the climbing aid 30 in a lateral direction orthogonal to a longitudinal direction or direction of travel of the heel unit 10, in order to prevent movement of two brake arms 60 outwards or in a horizontal direction.The first climbing aid 30 can have a contact surface 39 on an inwardly facing side of the at least one retaining projection 38, which, when the brake arrangement 50 is in the sliding position, contacts the contact section 64 of the brake arm 60 facing the contact surface 39 of the first climbing aid 30 in the active position. As in . Fig. 5 and subsequently even better in Fig. As can be seen in Figure 10, the contact surface 39 or, in the preferred case of two retaining projections 38 in the present embodiment, the contact surfaces 39 can extend obliquely outwards in the direction of the sliding board plane E, so that the facing contact sections 64 of the brake arms 60 slide into recesses 18 provided in the carriage 16, which ensures an even more stable locking.

[0040] In the Fig. Figures 6 to 10 show the brake arrangement 50 in a transitional position between the sliding position and the braking position.

Detail marked A, Fig. 9 a top view of the heel unit 10 from Fig. 6 and Fig. 10 a sectional view along line BB in Fig. 9. In the Fig. Figures 11 to 15 show the brake arrangement 50 in the brake position.

[0041] This shows Fig. 11 a perspective view of the heel unit 10, Fig. 12 a side view of the heel unit 10 from Fig. 11, Fig. 8 an enlarged view of the in Fig. 12 details marked with A, Fig. 13 a top view of the heel unit 10 from Fig. 11 and Fig. 15 a sectional view along line BB in Fig. 14.

[0042] With reference to the Fig. 7, Fig. 8 and Fig. Section 10 below describes a user-operated unlocking process for the brake assembly 50, i.e., an adjustment of the same from the sliding position to the braking position. The starting position is, for example, the one shown in Fig. 1 shown sliding position of the brake arrangement 50, wherein, as in the Fig. 2 and Fig. As can be seen in Figure 3, the first climbing aid 30 is in the active position and the second climbing aid 40 is in the ready position. If the second climbing aid 40 is rotated counterclockwise around the pivot axis S towards its passive position (shown in the Fig. 12 and Fig. 13) rotated, so the drive lug 44 of the second climbing aid 40 contacts the second contact section 36 of the first climbing aid 30 (see Fig. 8) and thus also causes the first climbing aid 30 to rotate counterclockwise. This allows, as in Fig. As can be seen in Figure 10, the contact between the contact surface 39 of the retaining projection 38 and the contact section 64 of the brake arm 60 is released, thus unlocking the brake arrangement 50.

[0043] Referring to the Fig. 7, Fig. 8 and Fig. The unlocking process of the brake assembly 50, as described in section 10, can be continued by further rotating the first climbing aid 30 counterclockwise until it too reaches its passive position. This state is described in the Fig. 12 and Fig. 13 shown.

[0044] When adjusting the brake assembly 50 from the sliding position to the braking position, in particular through the elastic preload of the brake assembly 50, at least one brake arm 60, or in the present embodiment both brake arms 60, realize a movement with both a horizontal and a vertical movement component. A movement of the brake arm in both the horizontal and vertical directions means that the movement of the brake arm 60 comprises a movement component in the horizontal direction and a movement component in the vertical direction. That is, a straight-line direction, inclined with respect to the sliding board, is also implied. Such a movement is carried out in particular by the brake section 62, or in the present embodiment the two brake sections 62, in order to engage with a surface under the sliding board in the braking position. As in Fig.As can be seen from Figure 15, the brake section 62 is located furthest below the sliding board plane E in the braking position of the brake arrangement 50 in order to achieve the greatest possible braking effect.
