Description

[0001] The invention relates to a heel holder for a combined downhill and touring binding for a ski. The heel holder comprises a base plate that can be connected to the upper surface of the ski, a connecting structure, a clamping device for securely holding a ski boot in the heel holder with at least one sole holder, a locking mechanism that selectively locks at least a portion of the heel holder in a downhill position or in a touring position, and a sliding mechanism with which the heel holder can be moved from a skiing position to a touring position. The heel holder can further include a pressure device that pre-tensions at least portions of the heel holder into the downhill position. The invention further relates to a ski with a ski binding having a heel holder according to the invention.

[0002] It is an object of the invention to provide a heel holder for a combined downhill and touring binding that enables simple, quick and reliable adjustment of the binding on the ski from the downhill position to the touring position and to provide a ski with the downhill and touring binding.

[0003] From DE 10 2010 006 218 A1, a ski binding with a toe unit and a heel unit is known, wherein the ski binding can be used for both ski touring and downhill skiing. To switch from downhill mode, in which the heel unit holds the rear end of a ski boot against the ski, to touring mode, in which the rear end of the ski boot is free of the heel unit, the heel unit can be moved longitudinally along the ski. To secure the heel unit in the respective position, the heel unit includes a locking lever with engagement elements that engage in recesses of a safety counter-structure to secure the heel unit in the respective position. To lock and unlock the heel unit, the locking lever is pivoted about its longitudinal axis.In the position where the locking lever secures the heel unit, a component is held in place behind the end of the locking lever (in the direction of skiing) by an engagement structure of the mounting structure, preventing the locking lever from unintentionally moving. WO 2012 / 024809 A1 applies to a touring heel binding with a dynamic glide zone.

[0004] These tasks are fulfilled according to the invention by the subject matter of claim 1 and claim 11.

[0005] The invention relates to a heel holder for a combined downhill and touring binding for a ski, comprising a base plate that can be attached to the top of the ski, a connecting structure and a tensioning device with a sole holder for securely holding a ski boot in the heel holder.

[0006] Furthermore, the binding includes a locking mechanism that optionally locks at least parts of the heel holder in a downhill position or in a touring position, and a sliding mechanism with which parts of the heel holder can be moved automatically or manually from the skiing position to the walking position.

[0007] In the following, the parts of the heel holder that can be moved from a downhill or riding position to a touring or walking position will also be referred to simply as the heel holder, for ease of reading the application. However, it is clear that the heel holder as a whole may comprise more parts, such as the base plate, which are not among the parts of the heel holder movable by the sliding mechanism in claim 1.

[0008] According to the invention, the locking mechanism comprises a locking lever that selectively locks the connecting structure in either the driving position or the walking position.

[0009] The tensioning device is a known type with at least one sole holder, which clamps the heel holder into a holding position in which the ski boot is securely connected to the ski. To get in and out of the ski, the tensioning device can be released, allowing the heel holder to detach the ski boot.

[0010] The parts of the heel holder that the locking mechanism locks in either the downhill or touring position may include, for example, the connecting structure and the tensioning device.

[0011] The sliding mechanism incorporates a spring element that is supported by a strut on the pressure body and by an inner wall of the connecting structure. When the heel holder is in the downhill position, the spring element is tensioned. In this position, the heel holder can then be locked with the locking lever. When the lock is released, the spring element relaxes, automatically moving the heel holder away from the binding's toe holder and into the walk position, where it is again locked by the locking mechanism.

[0012] The locking mechanism includes a locking lever that selectively locks the heel holder in either the downhill or touring position. The locking lever is connected to the linkage structure via a pivot joint with a pivot axis running parallel and perpendicular to the ski surface. The locking lever can be a single piece or consist of two or more separate lever sections. It can be made of plastic, reinforced plastic, or metal, or a combination of these materials.

[0013] To lock the heel holder, the pressure body has an engagement element, e.g., a toothed section, and the locking lever preferably has a counter-engagement element, e.g., a counter-toothed section, at a forward end region in the skiing direction. To lock the heel holder, the counter-engagement element on the locking lever engages with the engagement element on the pressure body. Besides a toothed engagement, the locking mechanism can also be formed, for example, by a pin that can engage in various recesses, or by other locking mechanisms known to those skilled in the art and suitable for the purpose.

[0014] The engagement element, or for example the toothing, can be directly molded onto the pressure body; that is, the engagement element can be formed in one piece with the pressure device, depending on the material, for example by injection molding, by deformation of a metal plate in a press, by a sintering process, or other suitable methods known to those skilled in the art.

[0015] Alternatively, the engagement element can be permanently connected to the pressure body, e.g. by gluing, soldering, welding or screwing, via rivets or by positive and / or force-fit connection.

[0016] The pressure body has at least two engagement positions: a first engagement position in which the counter-engagement element on the locking lever engages in the engagement element to lock the heel holder or parts of the heel holder in the skiing position, and a second engagement position in which the counter-engagement element on the locking lever engages behind the engagement element in the skiing direction to lock the heel holder or parts of the heel holder in the walking position.

[0017] The locking lever can be pre-tensioned in an engagement direction with the engagement element on the pressure body by a spring element that is supported on the locking lever and on an underside, e.g., of the connecting structure. This means that the spring element, or rather the spring force of the spring element, presses the counter-engagement element into the engagement element or into a space behind the engagement element, thus locking the counter-engagement element to the engagement element in both the driving and walking positions. This prevents the lock from unintentionally disengaging during driving, walking, or transport. The spring element can be a coil spring, a leaf spring, or a solid elastic body.

[0018] The spring element is preferably supported at the end of the locking lever that adjoins the area with the counter-locking element at the front in the direction of skiing. For this purpose, the locking lever may have a guide for the spring element, preventing it from slipping off the locking lever. At the other end, the locking lever may have an engagement recess into which a ski pole tip can engage. Using the ski pole, the locking lever is then pressed against the ski surface, compressing the spring element and thereby releasing the counter-locking element from the locking mechanism.

[0019] The pressure element is connected to the base plate in such a way that the pressure element and locking mechanism cannot move relative to the base plate during driving, walking, or transport. The pressure element and locking mechanism can be positioned between the base plate and the connecting structure.

[0020] To ensure that the heel holder can be moved in a controlled and repeatable manner between the downhill and touring positions, the pressure element can be pressed against a stop, preventing the heel holder from moving beyond the downhill position in the direction of skiing. This stop can, for example, be the back of the pressure element.

[0021] To press the pressure body against the stop, the heel holder can have a cylindrical retaining element with an attached or molded-in external thread, whereby the external thread can engage in grooves formed in the base plate. The external thread or the hollow cylinder can be screwed into the grooves into a desired position. A spring element, supported at the front end of the retaining element (in the direction of skiing) and against an inner wall of the pressure body, then presses the connecting structure against the rear end of the pressure body (in the direction of skiing).

[0022] The spring element additionally presses the retaining element against the direction of skiing, so that the flanks of the thread are pressed against the flanks of the grooves, thus preventing the retaining element from moving out of its set position on its own, e.g. due to vibration of the ski during downhill skiing.

[0023] The spring element also acts as a pressure spring for the heel holder, against whose resistance the connecting structure can be shifted a few millimeters against the ski's direction of travel when the ski boot is inserted into the heel holder. Even if the ski bends lengthwise, for example during a descent, the spring compensates for the shortening distance between the toe holder and the heel holder caused by the bending.

[0024] The locking lever can be connected to the linkage structure via a pivot joint. It can form a first and a second lever arm, with the first lever arm extending from the pivot joint to the spring element that biases the locking lever into the locked position, and the second lever arm extending from the pivot joint to the ski pole engagement point. The second lever arm is preferably longer than the first, which increases the unlocking force acting on the spring element. As previously mentioned, the locking lever can be formed in one piece or consist of several separate lever sections.

[0025] The locking lever can be operated by the ski pole and project rearward from the heel holder; less preferably, the locking lever can project laterally from the heel holder and / or fold flat against it. The locking lever, which preferably folds flat with the ski pole, can be spring-loaded into the folded-down position against the heel holder. To protect against excessive dirt and damage, the locking lever, or the portion of the first lever arm projecting from the connecting structure, can be protected by a bracket, which can be connected to the second connecting structure part.

[0026] The locking mechanism may include a locking lever connected to a spindle plate or carbon plate. The spindle plate is connected to the heel holder and, by means of the locking lever, can move the heel holder from the driving position to the walking position and lock it in the respective position.

[0027] The locking lever is connected to the ski in the direction of travel, in front of the heel catch and preferably also in front of a ski brake. For this purpose, a bracket is mounted on the ski surface in which the locking lever is mounted in a pivot joint, which, for clarity, will also be referred to as the lever pivot joint. The bracket can simultaneously form a guide for the spindle plate to prevent it from bending upwards. The bracket or guide extends to the base plate of the heel catch and is connected to the base plate in such a way that the two parts cannot move relative to each other on the ski surface, either in or against the direction of travel.

[0028] The spindle plate is connected to the locking lever in a further pivot joint, the spindle plate pivot joint, whereby the lever pivot joint is not identical to the spindle plate pivot joint, but is located at a finite distance from it. This forms a kind of toggle lever that can be pivoted beyond the dead center, where the axes of the lever pivot joint and the spindle plate joint lie on a horizontal line, in a forward position and in a rear position, resulting in the locking of the locking lever in the respective past-dead-center position.

[0029] When the locking lever is moved manually around the pivot axis of the lever's swivel joint, the spindle plate within the spindle plate's swivel joint is simultaneously moved, resulting in a linear movement of the spindle plate. This means that when the locking lever is in its forwardmost position on the ski, the heel holder is in the skiing position and locked in that position. If the locking lever is now moved backward manually within the lever's swivel joint, the spindle plate is simultaneously moved in the opposite direction of skiing, thereby shifting the heel holder from its skiing position to the walking position.

[0030] The spindle plate is connected at its front end (in the direction of skiing) to the locking lever via the spindle plate pivot joint. At its rear end (in the direction of skiing), the spindle plate is designed to connect to the linkage structure. Between the front and rear ends, the spindle plate may have a receptacle for a ski brake lock, which, in the skiing position of the heel holder, is positioned in front of the ski brake, allowing the ski brake to be activated if the ski detaches from the ski boot. In the walking position of the heel holder, the ski brake lock secures the ski brake to the ski.

[0031] To be connected to the heel support, the spindle plate extends over or into the base plate of the heel support and has a central rear section that can be designed to connect to a retaining element. This retaining element can be a cylindrical retaining element with an attached or integrally formed external thread. The external thread, or the helically extending webs of the external thread, can engage in grooves formed in the central rear section of the spindle plate.

[0032] The retaining element interacts in a known manner with a retaining element that includes a spring element. This spring element presses the heel holder into the skiing position and can be compressed when the skier steps into the heel holder or when the ski bends longitudinally, in order to vary the distance between a toe holder and the heel holder depending on the situation. Details of the retaining element and the other functional parts of the heel holder have already been described above in connection with the first embodiment of the invention; therefore, reference is made here to those descriptions for further details.

[0033] The central rear section of the spindle plate can be a separate part that is connected or connectable to the spindle plate. Alternatively, the central rear section can be formed integrally with the spindle plate.

[0034] The central rear section of the spindle plate can protrude downwards from the spindle plate. This section can engage in an opening in the base plate. The opening can, with its front end (in the direction of skiing), form a stop for the spindle plate or the rear central section in the skiing position, and with its rear end (in the direction of skiing), form a stop for the spindle plate or the rear central section in the walking position.

[0035] If the spindle plate has the described central rear area, the spindle plate moves all parts of the heel holder, except for the base plate, from the driving position to the walking position.

[0036] The connecting structure can be formed from several connecting structure parts in all versions. The first connecting structure part can be connected to the clamping device via a pivot joint, allowing the clamping device to be pivoted for entering and exiting the heel holder. The pivot axis of the pivot joint runs essentially parallel to the ski surface and perpendicular to the skiing direction.

[0037] A second connecting structure component can be guided linearly parallel to the ski surface in and against the skiing direction within the base plate and connected to the first connecting structure component in a further pivot joint, with this pivot axis being essentially perpendicular to the ski surface. The first connecting structure component can pivot relative to the second connecting structure component in this further pivot joint, thus ensuring lateral release of the heel holder upon application of sufficient force.

[0038] The release force for the lateral release can be adjusted by means of a release device, wherein the release device has a spring-loaded roller that can be moved in a cam transverse to the skiing direction. The cam can be connected to the second connecting structure part or formed as a single piece. The shape of the cam and the spring force of the spring element determine the magnitude of the lateral release force for triggering the lateral release of the heel holder.

[0039] The clamping device includes a sole holder. The sole holder can be formed from two separate partial sole holders, each comprising a sole holder element in the form of a roller that rests directly on the ski boot sole and rolls along the ski boot sole upon lateral release. This reduces the frictional force between the sole holder and the ski boot sole, so that the theoretical release force of the release device essentially corresponds to the actual release force and is not additionally increased by a frictional force of unknown magnitude between the sole holder and the ski boot sole.

[0040] The heel holder can have at least one climbing aid that can be pivoted from a secured position in the downhill position to a touring position. The climbing aid can be held in the secured position during downhill skiing and / or in the touring position by a spring element.

[0041] Preferably, the heel holder has at least two climbing aids, the first climbing aid supporting the ski boot at a first climbing angle and the second climbing aid supporting the ski boot at a second climbing angle different from the first. The climbing aid(s) can be secured in the locked position during skiing by a spring element or a common spring element. The same applies to securing the climbing aid in the folded-down walking position. Preferably, the two or more climbing aids can be pivoted into the walking position sequentially, starting with the climbing aid with the lowest climbing angle.

[0042] The invention further relates to a ski with a ski binding having the heel holder described above.

[0043] An exemplary embodiment of a heel support is shown below with reference to the figures. All essential features of the invention shown in the figures are part of the scope of the invention and can, individually or in the combinations shown, advantageously further develop the invention.

[0044] The figures show, in detail: Fig. 1 Exploded view of a first embodiment of the heel holder according to the invention Fig. 2 Side view of the assembled heel holder of the Fig. 1 Fig. 3 Longitudinal section through the heel holder of the Fig. 1 in the driving position at the height of the locking lever Fig. 4 Longitudinal section through the heel holder of the Fig. 1 in the walking position at the height of the locking lever Fig. 5 Longitudinal section through the heel holder of the Fig. 1 at the height of the stop Fig. 6 Longitudinal section through the heel holder of the Fig. 1 at the height of the release spring in the driving position Fig. 7 Longitudinal section through the heel holder of the Fig. 1 at the height of the release spring in the walking position Fig. 8 Cross-section through the heel holder of the Fig. 1 at the height of the release device for the lateral release Fig. 9 Exploded view of a second embodiment of the heel holder according to the invention Fig. 10 Longitudinal section through the heel holder of the Fig. 9 in driving position Fig. 11 Longitudinal section through the heel holder of the Fig. 9 in walking position

[0045] The Fig. Figure 1 shows an exploded view of a first embodiment of a heel retainer 1 for a ski binding. The heel retainer 1 comprises a base plate 2, a first connecting structure part 3a, and a second connecting structure part 3b, which together form a connecting structure 3. The second connecting structure part 3b has a cylindrical pivot axis 9 projecting vertically upwards, onto which the first connecting structure part 3a can be attached, so that the first connecting structure part 3a can be pivoted relative to the second connecting structure part 3b along the pivot axis 9, e.g., during a lateral release of the heel retainer.

[0046] The connecting structure part 3b has an extension 25 in the skiing direction with a hook-shaped front end 25a. The extension 25 forms a retaining device for a ski brake (not shown), which secures the ski brake against activation in the walking position.

[0047] Furthermore, the heel holder 1 has a clamping device 4 with a skeletal clamping device body 4a, which has a sole holder 5 consisting of a first partial sole holder 5a and a second partial sole holder 5b. In the exemplary embodiment, both partial sole holders 5a, 5b are identically constructed and each has a roller 6 and a rotary bearing 6a, wherein the roller 6 bears directly against a ski boot sole and minimizes frictional resistance between the ski boot sole and the sole holder 5, e.g., during a lateral release of the heel holder 1.

[0048] The clamping device 4 is connected to the first connecting structure part 3a in a pivot joint by means of a hollow cylindrical pivot axis 9, so that the clamping device 4 can be pivoted towards and away from a ski surface in the pivot axis 9.

[0049] Two climbing aids 7, 8 can be held in a secured position in the driving position of the heel holder 1 by means of a spring element not shown, and can be folded into a climbing position in the walking position of the heel holder 1.

[0050] The first connecting structure part 3a also forms a housing for a release device 11 for the lateral release of the heel holder 1 with a roller 11a guided in a cam 12. The cam 12, shown as a separate part in the exploded view, can be rigidly connected to the second connecting structure part 3b or formed in one piece.

[0051] Between the base plate 2 and the second connecting structure part 3b a pressure body 13 is arranged, which in the exemplary embodiment shows a toothing 14 molded on it.

[0052] A locking lever 15 has a mating tooth 23 whose teeth can engage with the toothing 14 to lock the heel holder 1 selectively in either the skiing or walking position. The locking lever 15 can be connected to the second connecting structure part 3b in a pivot joint 16 and has a first lever arm 15a and a second lever arm 15b. The mating tooth 23 is formed on the first lever arm 15a, and in the skiing direction, in front of the mating tooth 23, there is a cylindrical receptacle for a spring element 17. The spring element 17 can bear against the locking lever 15 and against a lower surface of the second connecting structure part 3b, thereby pressing the mating tooth 23 into the toothing 14.The second lever arm 15b has an engagement recess 18 at its end pointing away from the pivot joint 16, into which the skier can engage a ski pole tip to press the locking lever 15 onto the ski surface, thereby compressing the spring element 17 and moving the counter-tooth 23 out of the toothing 14.

[0053] The pressure body 13 has a semi-cylindrical receptacle 13a for a retaining element 19, which receives the pressure body 13. The retaining element 19 has a cylindrical retaining element body which has an external thread 20 at an end facing forward in the skiing direction, which can engage screw-type in grooves or slots 2a of the base plate 2, so that the retaining element 19 cannot move on its own in or against the skiing direction relative to the base plate 2.

[0054] A spring element 21, which is supported, for example, on an inner wall of the pressure body 13 and the retaining element 19 in an opening in the area of ​​the external thread 20, presses the heel holder 1 into the driving position and simultaneously the flanks of the external thread 20 against the sides of the groove or slots 2a, thereby creating an additional force transmission between the pressure body 13 and the base plate 2.

[0055] Another spring element 22 is supported by a crossbar 24, which is integrally formed on the receptacle 13a of the pressure body 13, and by an inner wall of the connecting structure part 3b. The spring element 22 is compressed when the heel holder 1 is in the downhill position and locked in this position by the locking lever 15. If the locking lever 15 is now actuated with the ski pole, so that the counter-tooth 16 disengages from the toothing 14, the spring element 22 or the release spring 22 moves the heel holder 1 against the direction of skiing relative to the base plate 2. That is, the heel holder 1 is moved linearly backward on the ski, so that the sole holder 5 no longer presses the ski boot sole against the ski and the ski boot heel can be lifted freely from the ski surface for walking.

[0056] The Fig. Figure 2 shows a side view of the assembled heel holder 1 of the Fig. 1. The locking lever 15 or the lever arm 15b extends beyond the end of the heel holder 1, so that the lever arm 15 is easily accessible to a ski pole tip and can be pressed onto the ski surface in the direction of the arrow using the ski pole tip. The locking lever 15 is connected to the connecting structure part 3b in a pivot joint 16.

[0057] The Fig. Figure 3 shows a longitudinal section through the heel holder 1 in the skiing position. The connecting structure 3a, 3b is in its foremost position, in which the ski can be used for skiing or downhill skiing. In this position, the sole holder 5 presses the ski boot onto the ski. The locking lever 15, or rather the counter-tooth 23, engages with the toothing 14 and thereby locks the heel holder 1 in the skiing position. The spring 17, which is supported on an inner wall of the connecting structure part 3b and on the lever arm 15a in an area in the skiing direction in front of the toothing 14, presses the lever arm 15, or rather the counter-tooth 23, into the toothing 14 and locks the lever 15 in this position. In the exemplary embodiment, the pressure body 13 projects rearward from the connecting structure part 3b in the driving position of the heel holder 1, and the lever 15 is arranged next to the pressure body 13.

[0058] The Fig. Figure 4 shows the heel holder 1 of the Fig. 3 in the walking position. To move from the skiing position to the walking position, the heel holder 1 on the ski was moved linearly against the direction of skiing. To do this, the skier had to insert the tip of a ski pole into the engagement recess 18 on the lever arm 15b and press the lever 15 onto the ski surface. This moves the heel holder 1 on the ski. Fig. The locking mechanism shown in Figure 3 between the toothing 14 and the counter-toothing 23 is released, and the heel holder 1 or the connecting structure 3, the tensioning device 4, and the locking lever 15 can be moved backwards on the ski against the direction of travel by the spring element 22, which is not shown because it is located behind the pressure body 13 in the illustration.

[0059] In the Fig. 4 is the heel holder 1 in the locked walking position, in which the counter toothing 23 on the lever arm 15a is pressed by the spring element 17 into a space in front of the toothing 14 connected to the pressure body 13 in order to lock the heel holder 1 in the walking position.

[0060] The Fig. Figure 5 shows a longitudinal midsection through the heel holder 1 of the Fig. 2. The retaining element 19 with the external thread 20 and the spring element 21, which is supported against the retaining element 19 and an inner wall of the pressure body 13, is shown. The external thread 22a engages in grooves 2a in the base plate 2 and thus determines the position of the retaining element 20 relative to the base plate 2. The spring element 21 presses the flanks of the external thread 22a against the rear walls of the grooves 2a (in the direction of skiing) and simultaneously pushes the pressure body 13 into a forward stop position on the base plate 2, in which the heel holder 1 can be locked in the skiing position.

[0061] The Fig. Figure 5 further shows the pivot axis 10 about which the connecting structure part 3b can be pivoted about the connecting structure part 3a, the release device 11 with the roller 11a and the cam 12.

[0062] The Fig. 6 and Fig. Figures 7 each show a longitudinal section through the heel holder 1 of the Fig. 2 at the level of the release spring 22. The release spring 22 is supported at one end on the crossbar 24, which is connected to the pressure body 13, and on an inner wall of the connecting structure part 3b. The Fig. Figure 6 shows the heel holder 1 in the driving position, in which the release spring 22 is tensioned. Fig. Figure 7 shows the heel holder 1 in the walking position, in which the release spring 22 has relaxed and thereby moved the heel holder 1 backwards on the ski into the walking position.

[0063] The Fig. Figure 8 is a cross-section through the heel holder 1 of the Fig. 2 at the height of a central axis of the release device 11 for the lateral release of the heel holder 1. The clamping device body 4a and the release device 11 with the roller 11a, both of which are received in the connecting structure part 3a, and the cam 12, which is arranged on the surface of the connecting structure part 3b, are visible. The connecting structure part 3b is guided in the base plate 2 so that the connecting structure part 3b can move relative to the base plate 2 in and against the skiing direction.

[0064] The pressure body 13 is arranged on the base plate 2, featuring the molded-on toothing 14 and the crossbar 24 against which the release spring 22 (not shown) is supported. Below the pressure body 13 is the retaining element 19, which has an external thread 20 that can engage in grooves 2a of the base plate 2. The lever 15 with the mating toothing 23 is shown in engagement with the toothing 14.

[0065] The Fig. Figure 9 shows a second embodiment of a heel holder 31 according to the invention, which, like the heel holder 1 of the first embodiment, is moved from the walking position to the running position and vice versa by a linear displacement on the ski surface in and against the direction of skiing.

[0066] The parts most important for the function of the heel holder 31 are shown, namely the connecting structure 3 and the tensioning device 4 with the sole holder 5, which is connected to the connecting structure 3 in a horizontal pivot axis 9, the base plate 52 and the sliding mechanism.

[0067] The base plate is designed to accommodate the connection structure 3, allowing the connection structure 3 to be moved linearly on the base plate 52 in and against the direction of skiing. The base plate 52 also features, among other things, two recesses 52a and 52b and a cutout 52c, the significance of which will be explained later.

[0068] The sliding mechanism comprises a fastening device 32 with a guide section 33, a spindle plate 34, and a locking lever 35. The locking lever 35 has a handle 36 that can be gripped by the user and two lateral arms 37, 38, each with two bores 37a, 37b and 38a, 38b, respectively. The two arms 37, 38 are connected at the level of the bores 37b, 38b by a web 39.

[0069] The fastening device 32 has a bracket 32a at its front end (in the direction of skiing) and two engagement elements 33a, 33b at its rear end (in the direction of skiing) of the guide section 33, which can engage in the recesses 52a, 52b of the base plate to connect the fastening device 32 to the base 52. The guide section 33 further has two lateral limits that form a guide for the spindle plate 34 and webs connecting the two limits that form a support for the spindle plate 34.

[0070] The bores 37a and 38a serve to connect the lever 35 to the mounting device 32 in a lever pivot joint. The bores 37b and 38b serve to connect the lever 35 to the spindle plate 34 in a spindle plate pivot joint. The web 39 forms a stop for the spindle plate 34 in the travel position of the heel holder 31.

[0071] The spindle plate 34 has a front end in the direction of skiing, which is configured to be connected to an axle body 46 with the lever 35 in the bores 37b, 38b. Furthermore, it has a receiving area 47, which is configured to be connected to a locking element 45 for a ski brake 40, and an end area 48 with a connection area 49 with grooves 49a for connecting the spindle plate 34 to the base plate 52 in the recess 52c and to the connection structure 3 by means of a retaining element 19 (not shown).

[0072] In the Fig. Figure 9 shows the ski brake 40, with a base body 41 that can be firmly connected to the ski and two pedal-actuated brake elements 42, 43. The ski brake 40 also has an opening 44 through which the spindle plate 34 is guided. The locking element 45 is also shown, which can be connected to the spindle plate 34 in such a way that it follows all movements of the spindle plate 34.

[0073] The Fig. 10 shows the heel holder 31 of the Fig. Figure 9 shows a sectional view in the skiing position. The lever 35 is in its forwardmost position in the skiing direction, a so-called over-center position, in which the lever 35 locks the heel holder 31 in the skiing position. In this position, the bridge 39 can additionally press against the spindle plate 34, thereby pulling the heel holder 31 or the spindle plate 34 into the skiing position with additional force. The ski brake 40 is not locked; the locking element 45 is in a position in which the skier can move the ski brake 40 or the brake elements 42, 43 into the locked position next to the ski by applying pressure to the pedal, and from which the ski brake 40 automatically releases when the pedal is released.

[0074] Furthermore, the Fig. 10 the retaining element 19 with the external thread 20, wherein the webs of the external thread 20 engage in the grooves 49a of the connection area 49 of the spindle plate 34 and thereby enable a linear displacement of the heel holder 31 in the recess 52c of the base plate 52.

[0075] To remove the heel holder 31 from the one in the Fig. To move the ski from the driving position shown in Figure 10 to the walking position, the user must grasp the handle 36 on the lever 35 and pivot the lever 35 approximately 180 degrees in the lever swivel joint. Simultaneously, the user must push the ski brake 40 into the driving position so that the locking element 45 can lock the ski brake 40 in the driving position.

[0076] In the Fig.Figure 11 shows the heel holder 31 in the walking position. The handle 36 of the lever 35 now points towards the ski tail, and the ski brake 40 is locked in the walking position by the locking element 45. The rear end of the spindle plate 34, or the receiving area 47, rests against the rear edge of the recess 52c of the base plate 52. At least one of the climbing aids 7, 8 can now be folded down from the clamping device 4 to enable walking.
