Description

[0001] The invention relates to a heel unit for a mountaineering ski binding, wherein the heel unit can be moved into an entry position, a middle position and a climbing position, and wherein the heel unit comprises the following:

[0002] - a ski brake which can be brought into an activated and inactivated position,

[0003] a heel clip having a rotatable holding body for holding a ski boot, wherein the holding body has a vertical axis of rotation, and

[0004] - Ski brake locking device,

[0005] wherein, in the activated position of the ski brake, the heel unit can be brought into an entry position and into an intermediate position by pivoting the holding body,

[0006] wherein, in the intermediate position of the heel unit, by actuation of the ski brake, the ski brake is brought from the activated position into the inactivated position, so that the heel unit is brought from the intermediate position into the climbing position, and

[0007] In this case, in the climbing position of the heel unit, the ski brake is moved from the inactive position into the active position by a rotation of the holding body, so that the heel unit is moved into the entry position.

[0008] Such a heel unit is known, for example, from AT 515 190 B1. The heel unit comprises a heel clip with a rotatable holding body ("binding body"), a ski brake ("braking device") and a ski brake locking device. The ski brake can be brought into an inactive position ("braking position") and an active position ("travel position"), wherein the ski brake is preloaded into the active position, in particular by means of a conventional torsion spring. The ski brake locking device consists of a first control part located at the holding body and a second control part positioned at the ski brake. In the active position of the ski brake, the heel unit can be brought into an entry position ("downhill position") and an intermediate position by rotating the holding body. In the intermediate position, the first control part points towards the front end of the ski and its end part is located above the second control part. Basically, there are two possibilities for operating the ski brake locking device. The first possibility is to actuate the ski brake when the heel unit is in the entry position, so that the second control part is rotated about a rotation axis extending in the transverse direction and approaches the plane of the ski, and when the ski brake is actuated, the holding body is rotated, whereby the first control part is displaced behind the second control part and blocks the second control part (ski brake in the inactive position, heel unit in the climbing position). In this method, the intermediate position is "bypassed". The second possibility, although not described in the publication, is quite common among users, namely to rotate the holding body starting from the entry position of the heel unit (heel unit in the intermediate position) and then actuate the ski brake, whereby the second control part performs the above-mentioned rotational movement and touches the second control part from above, whereby, under the application of appropriate force, the second control part is pushed away together with the entire holding body, so that the first control part is displaced behind the second control part and blocks the second control part (ski brake in the inactive position, heel unit in the climbing position). In the climbing position of the heel unit, the heel unit is moved back to the entry position by rotating the holding body.

[0009] In the case of the first possibility described above, actuation of the ski brake locking device according to AT 515 190 B1 is uncomfortable. In the case of the second possibility described above, greater mechanical loads occur, which is disadvantageous for the durability of the heel clip. In addition, there is the risk that the components of the ski brake locking device will freeze, so that the ski brake locking device can no longer be actuated or can only be actuated in a significantly more difficult manner.

[0010] Another heel unit of the above-mentioned type is known from AT 514 518 B1. This heel unit comprises a ski brake, a heel clip with a rotatable retaining body and a ski brake locking device with a hook. The heel clip has a protruding cam with a curved sliding surface on the outside of its housing ("upper part 26"), wherein the housing is preloaded toward the brake housing ("frame 28") of the ski brake by means of a compression spring aligned in the longitudinal direction of the ski. When the heel unit transitions from the entry position to the intermediate position, the heel clip rotates while being displaced rearwards (i.e. away from the brake housing) against the force of the compression spring, wherein the curved sliding surface on the cam comes into contact with a protrusion on the brake housing. At the same time, due to the rearward displacement of the heel clip, the hook of the ski brake locking device operatively connected to the heel clip is released ("activated"). When the ski brake is subsequently actuated, the hook pivots about an axis extending in the transverse direction, snaps into a component of the ski brake, so that the ski brake remains in the inactive position and the compression spring acting on the hook is preloaded more strongly. When the heel clip is rotated back, the hook pivots back by the compression spring acting on it, so that the ski brake is pressed into the active position by the torsion spring and the heel unit is in the entry position again.

[0011] Another heel unit of the above-mentioned type is known from EP 3 345 659 B1. This heel unit comprises a ski brake having a plate-shaped brake bearing, a brake holder and a preloaded brake holder pivotably mounted on the brake bearing. The heel unit can be moved into an entry position ("holding configuration"), a climbing position ("walking configuration") and an intermediate position. The brake bearing can be mounted displaceably in the longitudinal direction of the ski in the heel holder and is preloaded backwards in the activated position of the ski brake, so that the brake bearing and the brake holder are moved backwards. By rotating the heel clamp through 180°, the heel unit is moved from the entry position into the intermediate position. Here, a projection on the heel clamp presses the brake bearing forwards against the preload of the brake holder, whereby the brake holder is located within the range of action of the brake holder (intermediate position of the heel unit). If the ski brake is now actuated, the brake holder engages with the brake holder (ski brake in the inactive position, heel unit in the climbing position). When the heel unit transitions from the climbing position back to the entry position, the brake bracket is released by the brake retainer so that the snowboard brake is in the activated position.

[0012] Thus, a heel unit for a mountaineering ski binding is known in which a pivoting movement of the holding body interacts functionally with a ski brake locking device, which is desirable with regard to an operability of the ski brake locking device that is as simple and intuitive as possible.

[0013] In the case of ski brake locking devices known to date, there is a risk that the functionality of the ski brake locking device may be impaired by external influences which may, for example, lead to icing of components of the ski brake locking device.

[0014] The object of the invention is therefore to ensure reliable and faultless operation of a ski brake locking device in the case of a heel unit of the type mentioned above, in particular also in extreme weather conditions.

[0015] According to the present invention, the proposed object is achieved by the following means:

[0016] The ski brake locking device comprises a linearly displaceable, spring-loaded actuating lever connected to the ski brake and a slide guide in the heel clip.

[0017] The slide guide comprises a locking element which is aligned along the vertical rotation axis of the holding body, rotates together with the holding body and is displaced along the rotation axis, and is spring-loaded toward the plane of the ski.

[0018] wherein, in the retracted position of the heel unit, the locking element is in a released position, in which the ski brake remains in the activated position during actuation, and

[0019] wherein, in an intermediate position of the heel unit, the locking element is in a locking position, in which, when the ski brake is actuated, the actuation lever engages with the locking element against its spring loading and against the spring loading of the locking element, so that the ski brake remains in the inactive position and the heel unit is in the climbing position,

[0020] Therein, when the heel unit transitions from the climbing position to the entry position, the locking element is in the released position, whereby the actuating lever and the locking element are disengaged and the actuating lever is pushed back or retracted by its spring loading, so that the ski brake is in the activated position.

[0021] In the heel unit according to the invention, the two engageable and disengageable components of the ski brake locking device, namely the spring-loaded, specially mounted locking element and the spring-loaded actuating lever, form a "locking mechanism" located inside or in the region of the heel clip, which is particularly well protected from external influences, such as mechanical loads or external influences that cause ice formation. Thus, a reliable and faultless operation of the ski brake locking device is ensured.

[0022] According to a preferred embodiment, the actuation lever is spring-loaded in the longitudinal direction of the ski and towards the front end of the ski, thereby supporting a functionally reliable, compact structure.

[0023] Yet another advantageous embodiment in this respect is characterized in that the actuating lever is a push rod which is spring-loaded by means of a prestressed compression spring or a pull rod which is spring-loaded by means of a torsion spring.

[0024] In this implementation, it is also advantageous in the following cases:

[0025] a) the push rod and compression spring are part of the preload device that preloads the snowboard brake into the activated position, or

[0026] b) The torsion spring constitutes a pretensioning means which pretensions the ski brake into the activated position.

[0027] In variant a), the push rod and the compression spring therefore perform a dual function, thereby saving components and thus reducing weight.

[0028] Furthermore, in the last-mentioned embodiment, it is advantageous if the actuating lever is a push rod which has a supporting projection, in particular an annular supporting projection, on its interior, on which the compression spring is supported.

[0029] Another preferred embodiment provides that the locking element and the actuating lever each have an inclined sliding surface which is aligned parallel to one another when the locking element is in the locking position and which contacts one another when the heel unit transitions from the intermediate position into the climbing position. This measure protects the ski brake locking device particularly reliably against ice buildup.

[0030] The last-mentioned and preferably implemented further developments described below provide additional support for a functionally reliable and compact design of the ski brake locking device.

[0031] One of the improved solutions is that the actuating rod has a locking projection, the cross section of which is particularly triangular, the sliding surface is formed on the locking projection, and the actuating rod can engage with the locking element through the locking projection.

[0032] Another improvement is that the sliding surface of the locking element is formed on one end of the locking element.

[0033] Another preferred embodiment is characterized in that the guide rail has a guide rail which is annular in a top view and has two diametrically opposite lowest points and two diametrically opposite highest points, and the locking element has two diametrically opposite control projections which are guided on the guide rail. This ensures particularly reliable guidance of the locking element.

[0034] Another preferred embodiment provides that the holding body can be rotated about the vertical rotation axis by means of a combined axial radial bearing formed in the heel clip, the combined axial radial bearing comprising a clamping device, wherein the holding body can be brought into a first position and a second position by rotating the holding body, wherein the clamping device holds the holding body in the respective position, and wherein the locking element is located in a through-hole formed in the region of the axial radial bearing and extending along the vertical rotation axis, wherein the locking element is in the locked position when the holding body is in the first position and in the released position when the holding body is in the second position, and wherein a part of the slide guide, in particular the slide track, is located in the through-hole. This ensures that the locking element is particularly well protected from external influences.

[0035] In the last-mentioned preferred embodiment, it is preferred that the axial radial bearing and the clamping device include a common, linearly displaceable, spring-loaded slider, and the axial radial bearing also includes a tower-shaped bearing component, wherein the slider and the tower-shaped bearing component act together so that the retaining body is rotatably mounted on the tower-shaped bearing component.

[0036] Another preferred embodiment is characterized in that the heel clip comprises a guide plate having a plate-shaped base part having a groove formed on the underside and extending in the longitudinal direction of the snowboard, in which groove the actuating lever is guided, wherein the actuating lever preferably has two lateral bridge-shaped guide projections extending parallel to the plane of the snowboard, which are guided on bridge-shaped support projections extending parallel to each other, which support projections protrude into the groove formed on the underside of the base part. As a result, the push rod is particularly well protected from external influences, in particular from ice formation.

[0037] In the two last-mentioned preferred embodiments, an advantageous variant is that the tower-shaped bearing part is a component of the guide plate and is located on the base part of the guide plate, wherein the through-hole in which the locking element is located passes through the tower-shaped bearing part and the plate-shaped base part.

[0038] Another preferred embodiment is characterized in that the actuating lever has a cross-shaped receptacle in which the brake support bolt of the brake support of the ski brake is mounted so as to be pivotable about the brake support bolt. This ensures that the ski brake can be mounted particularly advantageously on one component of the ski brake locking device (the actuating lever).

[0039] Another advantageous embodiment provides that the holding body has a housing with a receptacle which is designed in particular as a blind hole and preferably in the form of an elongated hole, in which the locking element is received in a rotationally fixed manner, wherein the locking element in particular has a locking element end section corresponding to the receptacle which is flattened on two opposite sides parallel to each other. This embodiment also contributes to particularly good protection of the ski brake locking device against ice accumulation.

[0062] The invention relates to a heel unit for a mountaineering ski binding which, in addition to the heel unit, also comprises a front unit, for example a front clip designed in a manner known per se.

[0063] In the description and claims, reference is made to a heel unit mounted on a snowboard. For the sake of clarity, illustrations of the snowboard are omitted. Some terms used subsequently are defined below.

[0064] "Ski flat" is the flat part of the upper side of the ski to which the mountaineering ski bindings are attached.

[0065] The term “longitudinal direction of the snowboard” means the longitudinal direction of the snowboard as it appears in a plan view onto the plane of the snowboard.

[0066] The “center plane of the longitudinal cross-section of the snowboard” is the plane which is perpendicular to the plane of the snowboard and extends through the snowboard centrally in the longitudinal direction of the snowboard.

[0067] The "transverse direction" is a direction which is at a constant distance from the plane of the snowboard and which, in a top view of the plane of the snowboard, extends perpendicularly to the longitudinal direction of the snowboard. Thus, the transverse direction is perpendicular to the center plane of the longitudinal cross section of the snowboard.

[0068] Descriptions of directions and positions or expressions relating thereto, such as the "upper side" or "lower side", "vertical", "above", "from above", "back side" etc. of a component, refer to the direction of the relevant component relative to the ski or the plane of the ski, the longitudinal direction of the ski, the transverse direction of the ski or the front or rear end of the ski.

[0069] First, the arrangement and design of the components of the heel unit are discussed, followed by a discussion of the function of the heel unit.

[0070] like Figure 1 Combination Figure 2a As shown, the heel unit includes a guide track 1, a heel clip 2 ( Figure 2a ) and a ski brake 3 connected to the heel clip 2.

[0071] The guide rail 1 can be mounted on a snowboard in a known manner and is provided on its upper side with a surface recess 1a ( Figure 1 ), in which a central thread-like engagement structure 1b ( Figure 1 ), the joint structure 1b is composed of alternating and continuous concave and convex parts. Figure 2a ) can be linearly displaced on the guide rail 1 together with the ski brake 3 and can be fixed in a variable position on the guide rail 1 and released again.

[0072] The ski brake 3 is designed to be substantially symmetrical with respect to the center plane of the longitudinal cross section of the ski, and comprises a brake housing 4, a brake pedal 5, two brake levers 6 and a brake support 7 ( Figure 1 ).

[0073] according to Figure 1 The brake housing 4 has: two lateral through holes 4a on the side facing the front end of the ski, the two lateral through holes 4a extend in the transverse direction and aligned with each other; a groove 4c ( Figure 5 ), the structure of the groove will be further discussed; located between the through hole 4a and the groove 4c ( Figure 5 ) in the area between them, extending in the lateral direction; and a slit-shaped recess 4d located in the center plane of the longitudinal cross-section of the ski and opening toward the front end of the ski.

[0074] The brake pedal 5 has two through holes 5a ( Figure 2b : a through hole 5a can be seen, the two through holes 5a extend in the transverse direction toward the front end of the ski and are aligned with each other; and two U-shaped receiving portions 5b (one of which is visible), the two U-shaped receiving portions 5b are constructed at the edge of the brake pedal 5 and are aligned with the through hole 5a ( Figure 2b ) aligned, toward the corresponding edge and lower side opening of the brake pedal 5; and through hole 5c ( Figure 2b , note: the through hole 5c is blocked), which faces the end of the ski, extends in the transverse direction and passes through the central plane of the longitudinal section of the ski, and the through hole 5c is interrupted in sections by a slit-shaped recess 5d that passes through the brake pedal 5 perpendicular to the plane of the ski.

[0075] The brake support 7 is located substantially in the center plane of the longitudinal cross section of the ski, and has: a through hole 7a at its end region facing the front end of the ski; a through hole 7b at its end region facing the rear end of the ski; and a cam-shaped protrusion 7d located below the through hole 7b and closer to the plane of the ski relative to the through hole 7b; and a brake support bolt 7c, which is constructed on the protrusion, protrudes on both sides and particularly penetrates the brake support 7. The through holes 7a, 7b and the brake support bolt 7c are oriented in the transverse direction, respectively.

[0076] The brake support 7 reaches into the recess 5d of the brake pedal 5 in the region of its through hole 7a and is secured by a brake pedal bolt 8 ( Figure 2b , through hole 5c is blocked) is connected to the brake pedal 5 in a manner that it can be pivotally mounted around the brake pedal bolt 8. In addition, the brake support 7 reaches into the slit-shaped recess 4d of the brake housing 4 in the region of its through hole 7b and is engaged by the brake bolt 9 (see Figure 2b , Figure 2c , through hole 7b is blocked) is connected to brake housing 4 in a pivotable manner. In addition, brake support 7 is connected to the ski brake locking device via brake support bolt 7c, which will be described in detail later.

[0077] The brake lever 6 is designed in a manner known per se, extends through the through hole 4a of the brake housing 4 and is received in the receiving portion 5b and the through hole 5a on the lower side of the brake pedal 5 (see Figure 2a , Figure 2b ).

[0078] like Figure 1 Combination Figure 2a As shown, the heel clip 2 ( Figure 2a ) includes a guide plate 10 and a retaining body 11 located on the guide plate ( Figure 2a ) and other components ( Figure 1 ), which component will be discussed in more detail below.

[0079] according to Figure 1 The guide plate 10 is composed of a plate-shaped base component 12 and a substantially cylindrical, tower-shaped bearing component 13 which is located on the base component 12 and is integrally formed with the base component 12 .

[0080] The base member 12 is designed to be symmetrical with respect to the center plane of the longitudinal cross section of the snowboard (see Figure 7 ), having a flat upper side 12a extending parallel to the plane of the ski and an engagement protrusion 12b pointing to the front end of the ski, the engagement protrusion 12b being designed to engage with a groove 4c ( Figure 5 ) and engages in a releasable manner in a shape-fitting manner into the groove 4c. Figure 6 As shown, the base part 12 is provided with an elongated groove 12c extending in the longitudinal direction of the ski and extending through the entire base part 12 on its lower side, and the groove 12c is designed as a sleeve 12c' at the end facing the front end of the ski (see Figure 2c ) and has a covering surface 12c". facing away from the plane of the ski. Starting from the covering surface 12c", there is a groove 12d which extends deeper into the base part 12 than the groove 12c and is rectangular in a top view. At the end of the groove 12c facing the front end of the ski, two bridge-shaped supporting protrusions 12e opposite to each other are formed, which protrude into the groove 12c and extend parallel to each other. In a top view, they partially extend on the sides of the groove 12d and protrude beyond the groove 12d on both sides of the longitudinal extension.

[0081] according to Figure 1 The bearing part 13 is located on the upper side 12a of the base part 12, wherein the bearing part is centrally configured on the upper side 12a with respect to the transverse direction and is configured to be offset toward the front end of the snowboard with respect to the longitudinal direction of the snowboard. The bearing part 13 consists of a lower bearing part 13a and a disc-shaped upper bearing part 13b centrally located on the lower bearing part, and the entire outer circumference of the upper bearing part 13b protrudes beyond the lower bearing part 13a.

[0082] The lower bearing portion 13a has a rear support surface 13a' (13a') extending perpendicularly to the plane of the snowboard and perpendicularly to the center plane of the longitudinal cross-section of the snowboard and facing the end of the snowboard. Figure 7 , Figure 8 ,exist Figure 7 The lower middle bearing portion 13a is not labeled) and the lateral support surface 13a extending perpendicularly to the plane of the ski board and perpendicularly to the rear support surface 13a' (see Figure 7 , Fig. 9 ).

[0083] according to Figures 7 to 9 , the bearing member 13 (ie, the lower bearing portion 13a ( Figure 8 , Fig. 9 ) and the upper bearing portion 13b ( Figure 8 , Fig. 9 )) and the base part 12 are penetrated by a through hole 14 of circular cross section, which extends perpendicularly to the plane of the snowboard and centrally through the bearing part 13 and appears at the bottom side of the base part 12 at the groove 12d ( Figure 6 , Figure 8 ).

[0084] In the lower bearing portion 13a ( Figure 8 , Fig. 9 ), the guide protrusion 15 ( Figure 7 , Figure 8 ) is constructed at the lower end portion of the through hole 14 facing the plane of the snowboard and adjacent to the groove 12d ( Figure 8 ) in the region, the guide protrusion 15 is in a plan view ( Figure 7 ) surrounds the lower bearing portion 13a in an annular shape ( Figure 8 , Fig. 9 ), relative to the central plane of the longitudinal cross-section of the snowboard and relative to the transverse plane E1 extending perpendicularly to the central plane of the longitudinal cross-section of the snowboard in a top view ( Figure 7 , the transverse plane E1 coincides with the line IX-IX), and the guide protrusion 15 causes the through hole 14 to have a hole end portion 14a narrower than the rest of the through hole 14. On the upper side of the guide protrusion 15 ( Figure 7 , Figure 8 ) forms a circularly surrounding slideway track 15a ( Figure 7 , Figure 8 ), the slide track 15a (according to the symmetry of the guide protrusion 15) is constructed relative to the central plane of the longitudinal section of the snowboard and the transverse plane E1 ( Figure 7 The slideway track 15a has two lowest points 15a' (15a') opposite to each other in the diameter direction and closest to the plane of the ski board. Figure 7 , Figure 8 ), the central plane of the longitudinal cross-section of the ski passes through these two lowest points 15a'; and two highest points 15a" (diametrically opposite to each other and farthest apart from the plane of the ski) Figure 7 , Fig. 9 ), transverse plane E1( Figure 7 ) passes through these two highest points 15a". The slide track 15a is continuously (without jump points) and uninterruptedly inclined from the highest point 15a" to the lowest point 15a'.

[0085] like Figure 1 Combination Figure 2cAs shown, a groove 12c ( Figure 2c ), from the front end of the ski to the rear end of the ski, there are: a push rod 16 that can be displaced in the longitudinal direction of the ski and is spring-loaded toward the front end of the ski; a mechanically preloaded compression spring 17 supported at the longitudinal end of the push rod 16; and a screw-shaped adjustment element 18, which is connected to the engagement structure 1b (see Figure 1 ) is engaged, and its relative position with the engaging structure 1b is adjustable, and the heel clip 2 ( Figure 2c ) and the ski brake 3 on the guide rail 1 ( Figure 1 ) position. The push rod 16, the compression spring 17 and the adjusting element 18 form a preload device 35 ( Figure 1 ), which will be described in more detail below.

[0086] according to Fig.10 The push rod 16 is composed of a rod-shaped push rod portion 16a facing the front end of the ski and a push rod portion 16b facing the front end of the ski. The cross section of the push rod portion 16b is perpendicular to the central plane of the longitudinal cross section of the ski, and is designed to be arc-shaped and open toward the plane of the ski (based on Figure 2b , Figure 2c The push rod portion 16a is provided with a cross-shaped receiving portion 16c opened toward the upper side, and the receiving portion 16c is composed of a receiving groove 16c' extending in the transverse direction and penetrating the push rod portion 16a neither in the transverse direction nor perpendicular to the plane of the ski board, and a receiving slit 16c" intersecting the receiving groove 16c', extending in the longitudinal direction of the ski board and opening upward and toward the front end of the push rod portion 16a. The push rod portion 16b has a locking protrusion 16d formed on the upper side of the push rod portion, two lateral bridge-shaped guide protrusions 16e extending parallel to the plane of the ski board, and a supporting protrusion 16f located inside the push rod portion, which is annular in the embodiment ( Figure 2b , Figure 2c , the annular shape is not visible). The locking projection 16d is or is substantially in the shape of a right triangle when viewed in the longitudinal section of the ski and has, when viewed in the cross section, a flat, inclined sliding surface 16d' forming the base of the triangle and inclined towards the ski plane towards the end of the ski (see Figure 2b , Figure 2c ). Therefore, the sliding surface 16d' is inclined relative to the plane of the snowboard.

[0087] like Figure 2c Combination Fig.10 As shown, the push rod 16 is positioned in the groove 12c of the base member 12 ( Figure 2c ) and passes through the sleeve 12c'( Figure 2c ), so that the cross-shaped receiving portion 16c ( Fig.10 ) protrudes from the base member 12 (more precisely, from the sleeve 12c') toward the front end of the snowboard. Figure 2c )), locking protrusion 16d( Fig.10 ) in the groove 12d of the base member 12 ( Figure 2c ) is guided, the guide protrusion 16e ( Fig.10 ) is placed flat on the base member 12 ( Figure 6 ) on the support protrusion 12e, and compress the spring 17 ( Figure 2c ) of the spring bearing surface on the support protrusion 16f ( Figure 2c ) and regulating element 18 ( Figure 2c ) is formed on the surface so that the compression spring 17 ( Figure 2c ) Push rod 16( Figure 2c ) is pressed toward the front end of the ski board. Brake support bolt 7c ( Figure 2c ) is inserted from above into the cross-shaped receiving portion 16c ( Fig.10 ), wherein the brake support member 7 ( Figure 2c ) to be able to go around the brake support bolt 7c ( Figure 2c ) is pivotally mounted in the cross-shaped receiving portion 16c ( Fig.10 ) and accommodating slit 16c" ( Fig.10 ) ensures that when the brake pedal is depressed 5 ( Figure 2c ), the brake support member 7 ( Figure 2c ) and the required relative movement between the push rod 16.

[0088] As mentioned above, the compression spring 17 ( Figure 2c ) is mechanically preloaded and loads the push rod 16. As long as the ski brake 3 ( Figure 2c ) has not yet been installed, the push rod portion 16b ( Fig.10 ) can ensure that the push rod 16 cannot move forward from the base member 12 ( Figure 2c ) out. When the ski brake 3 and the guide plate 10 ( Figure 1 ) connection (wherein, as described above, the connection is made by engaging the protrusion 12b ( Figure 1 ) and groove 4c( Figure 5 ) is realized), brake support bolt 7c ( Figure 1 ) is introduced into the cross-shaped receiving portion 16c ( Fig.10 ), so that the push rod 16 ( Figure 1 , Figure 2c , Fig.10 ) in compression spring 17( Figure 1 , Figure 2c ) is moved backward when the preload is generated. Therefore, once the ski brake 3 is in contact with the guide plate 10 ( Figure 1) connection, the push rod 16 and the brake support 7 through the push rod 16, and then the ski brake 3 is spring loaded ( Figure 2c Thus, the push rod 16, the compression spring 17 and the adjusting element 18 constitute the already mentioned preload device 35 ( Figure 1 ).

[0089] like Figure 1 As shown, the retaining body 11 ( Figure 2a ) has a housing 19, which consists of an elongated rectangular housing lower part 20 and a housing upper part 21 pushed onto the housing lower part, wherein the housing upper part 21 is connected to the housing lower part 20 by a bolt connection, and the bolt connection includes two bolts 22 extending in the transverse direction.

[0090] according to Fig.11 The elongated hole-shaped opening 20a extending perpendicularly to the plane of the ski and aligned in the longitudinal extension direction of the shell lower part 20 penetrates the shell lower part 20, so that the shell lower part 20 is designed in a frame shape. Figure 1 ) is constructed with: a guide protrusion 20b, which, in a top view (viewing direction perpendicular to the plane of the ski), is U-shaped and surrounds one longitudinal end of the opening 20a; and two guide protrusions 20c, which are located at the other longitudinal end of the extension direction of the U-shaped legs of the guide protrusion 20b, are opposite to each other, and extend straightly when viewed from a top view, wherein the guide protrusions 20b and 20c terminate at the same height level inside the shell lower part 20 perpendicular to the plane of the ski (see Figure 1 The guide protrusions 20b and 20c make the opening 20a have a U-shaped opening portion 20a' and a circular opening portion 20a" on the outer periphery. In the housing lower part 20, a threaded hole 20d is formed on the side facing the circular opening portion 20a" (at Fig.11 Not visible in , see Figure 2b , Figure 2c ), the threaded hole 20d is opposite to the U-shaped opening portion 20a' in the diameter direction and penetrates the lower part of the housing 20. In order to assemble the holding body 11 ( Figure 2a ), the housing lower part 20 can be pushed from above onto the bearing component 13 ( Figure 1 )superior.

[0091] like Figure 1 Combination Figure 2b and Figure 2c As shown, in the lower part 20 of the housing (only Figure 1 In the area marked in Figure 1 ), compression spring 23 and adjustment mechanism 25, which together constitute a device for holding body 11 ( Figure 2a) of the clamping device 36 ( Figure 1 The slider 24 is spring-loaded by the compression spring 23, wherein the slider 24 and the compression spring 23 are arranged in the housing lower part 20 ( Figure 1 Combination Figure 2b , Figure 2c The lower part 20 of the housing and the slider 24 are only Figure 1 ), and the adjustment mechanism 25 is screwed into the threaded hole 20d ( Figure 2b , Figure 2c ).according to Figure 1 The slider 24 has a stepped protrusion 24a and a blind hole 24b (24b) extending at a constant distance from the plane of the ski board on its opposite sides. Figure 2b ), and further, on the other side opposite to each other, there are bridge-shaped guide protrusions 24c extending straight and parallel to each other and maintaining a constant and consistent spacing with the plane of the ski. The compression spring 23 is supported in the blind hole 24b ( Figure 2b )Internal and regulatory mechanisms 25( Figure 2b , Figure 2c ) so that one spring bearing surface is formed by the blind hole 24b and the other spring bearing surface is formed by the adjustment mechanism 25. The slider 24 is guided by its guide protrusion 24c ( Figure 1 ) and guide protrusions 20b, 20c ( Fig.11 ) is guided in a linearly displaceable manner in the longitudinal extension direction of the housing lower part 20, wherein the slide 24 is pressed toward the bearing component 13 by the compression spring 23 so that the stepped protrusion 24a engages below the upper bearing part 13b ( Figure 2b , Figure 2c ).

[0092] Holding body 11( Figure 2a ) through the lower part of the housing 20 ( Figure 1 ) in the bearing component 13( Figure 1 ) can be mounted around the bearing component 13 and thus around the through hole 14 ( Figure 1 )'s vertical rotation axis a1( Figure 2b The vertical rotation axis a1 is perpendicular to the plane of the snowboard.

[0093] Bearing component 13( Figure 1 ) and the clamping device 36( Figure 1 ) together form a combined axial radial bearing, which allows the retaining body 11 ( Figure 2a ) relative to the guide plate 10 ( Figure 1 , Figure 2a ) pivoting movement.

[0094] according to Figure 1 and Figure 2aThe housing upper part 21 has a retaining element 21a on its upper side located at the edge of the end region, and two intermediate retaining elements 21b (in the middle) that are spaced in the same manner and opposite to each other. Figure 2a Only one can be seen in the figure) and an arc-shaped, edge-side retaining element 21c. A retaining bracket 26 designed as a U-shaped bracket surrounds the retaining elements 21a, 21b, 21c on the outside, which is in contact with the retaining elements 21a, 21b, 21c and presses on the retaining elements 21a, 21b, 21c due to its design, and has two free ends for accommodating a correspondingly designed ski boot and rests on the arc-shaped, edge-side retaining element 21c in the area of ​​its curved section, wherein the retaining elements 21a, 21b protrude beyond the retaining bracket 26 in the manner of a clip ( Figure 2a ) on the upper side. By means of the fixing element 27, the retaining bracket 26 is fixed to prevent being pushed down from the housing upper part 21. Figure 1 As shown, a climbing aid spring 28 which surrounds the middle retaining element 21b in a U-shape is located between the middle retaining elements 21b. Above the climbing aid spring 28, a bolt 29 is arranged, which is guided between the middle retaining elements 21b and attached to the edge-side retaining elements 21a, 21c, and two climbing aids 30, 31 are pivotably mounted on the bolt 29. During the pivoting movement, the climbing aids 30, 31 cooperate with the climbing aid spring 28, so that the climbing aid spring 28 is pressed downwards, thereby keeping the climbing aids 30, 31 in place.

[0095] according to Figure 2b , Figure 2c , Figure 2d The housing upper part 21 has a receiving portion 32 extending from its underside and perpendicular to the plane of the ski (see Figure 4c ), the receiving portion 32 is located in the through hole 14 ( Figure 1 ) is designed as a blind hole, and the cross-section parallel to the plane of the ski is rectangular or oblong.

[0096] according to Figure 1 , Figure 2b , Figure 2c and Figure 2d The pin-shaped, elongated locking element 33, which is spring-loaded toward the plane of the ski, is located on the housing 19 ( Figure 1 ) is positioned in the through hole 14 that penetrates the bearing component 13 and the base component 12. Therefore, the locking element 33 is aligned along the vertical rotation axis a1 ( Figure 2b ), located at the heel clip 2( Figure 2b , Figure 2c ) and the distance from the plane of the ski board is greater than that of the push rod 16 ( Figure 1 , Figure 2b , Figure 2c ) further. Fig.12 The locking element 33 has an upper locking element end portion 33a, which is flattened on two opposite sides parallel to each other and is accommodated in the accommodating portion 32 (under the housing upper portion 21) in a rotation-proof manner. Figure 2b , Figure 2c , Figure 2d two diametrically opposed control projections 33b (one can be seen), the locking element 33 is placed on the guide groove track 15a of the guide projection 15 of the through hole 14 inside the control projection 33b ( Figure 2d ); and the lower locking element end portion 33c located in the hole end portion 14a (see Figure 2d ). The upper locking element end portion 33a (due to its flattening) has two flat surfaces 33a' aligned parallel to each other. The free end of the lower locking element end portion 33c is chamfered below a control protrusion 33b, so that the lower locking element end portion 33c has a flat inclined sliding surface 33c' at its free end. The sliding surface 33c' is therefore inclined relative to the plane of the snowboard. Fig.12 Combination Figure 1 As shown, the locking element 33 is positioned in the through hole 14 ( Figure 1 ) (ie in the entered position of the heel unit, as will be further described), the sliding surface 33c' ( Fig.12 ) points to the lower bearing portion 13a ( Figure 1 )'s lateral support surface 13a" ( Figure 1 )(See also Figure 2d ).like Fig.12 As shown, the compression spring 34 is pushed onto the locking element 33 from above, wherein one of the spring bearing surfaces is formed by the control projection 33b (see Figure 2d ), and another spring bearing surface is formed at the outlet of the receiving portion 32 (see Figure 2b to Figure 2d The compression spring 34 presses the locking element 33 toward the plane of the ski board. The locking element 33 loaded by the spring is in contact with the slide track 15a ( Figure 7 ) together form the slide rail guide portion.

[0097] The functions of the follower unit are described below.

[0098] The heel unit can be in an entry position, a descent position, an intermediate position and a climbing position.

[0099] The ski brake 3 can be in an activated position and in an inactivated position.

[0100] The locking element 33 can be in a released position and a locked position.

[0101] The retaining body 11 and the slider 24 can be in a first position corresponding to each other and a second position corresponding to each other.

[0102] The heel unit includes the ski brake lock and the side release function group.

[0103] Heel unit in entry position

[0104] Figure 2a to Figure 2d The heel unit is shown in the entry position for entering a mountaineering ski binding and subsequently securing a ski boot. Figure 2a In the entry position, the holding body 11 is aligned relative to the guide plate 10 so that a ski boot inserted into the front unit with a corresponding receptacle for the holding bracket 26 can engage with the holding bracket 26 (first position of the holding body 11). Figure 2b and Figure 2c As shown, the compression spring 17 presses the push rod 16 toward the front end of the ski, whereby the brake pedal 5 is pressed upwards via the brake support 7 and the free end of the brake lever 6 is pressed downwards, so that the ski brake 3 is in the above-mentioned activated position, i.e., by means of the preload device 35 ( Figure 1 ) is preloaded in this activated position. If the ski brake 3 is in the activated position, the brake lever extends out of the plane of the ski in a known manner and engages the ground. The compression spring 23 pushes the slider 24 ( Figure 1 ) is pressed toward the bearing component 13, wherein the stepped protrusion 24a ( Figure 1 ) is pressed against the rear support surface 13a' of the lower bearing part 13a, thereby fixing the heel clip 2 to prevent unintentional rotation (first position of the slider 24). By rotating the adjustment mechanism 25, the preload force of the compression spring 23 and thus the release force to be overcome for the lateral release of the heel clip 2 are adjusted (see the heel unit in the downhill position). The locking element 33 and its control projection 33b ( Fig.12 ) is located at the upper part 15a of the chute track ( Figure 7 , Fig. 9 )'s highest point 15a" ( Figure 7 , Fig. 9 ) so that the lower locking element end portion 33c is located outside (above) the groove 12d of the base member 12 ( Figure 2c ), wherein, as previously described, the locking element 33 is inserted with the sliding surface 33c' facing the lateral support surface 13a" of the lower bearing portion 13a ( Figure 2d ). The locking element 33 is in a release position which defines a first position of the locking element 33 relative to the plane of the snowboard.

[0105] The heel unit is in the downhill position (not shown)

[0106] When entering the heel unit, the ski boot engages in a known manner with the holding bracket 26 of the holding body 11, wherein the brake lever 6 is moved by the brake pedal 5 essentially into the plane of the ski, i.e. rests to the side of the ski, so that the ski brake 3 is in the inactive position. Thus, if the ski brake is in the inactive position, the brake lever is located to the side of the ski and therefore does not engage the ground. Figure 1 It can be seen that during the entry process, the push rod 16, which is articulated to the brake pedal 5 via the brake support bolt 7c of the brake support 7, is pressed towards the end of the ski against the force of the compression spring 17. After the entry, the heel unit is in the downhill position, the ski brake 3 is in the inactive position, the locking element 33 remains in the released position, and the slide 24 and the retaining body 11 remain in their first position.

[0107] If the force acting in the lateral direction exceeds the release force (see heel unit in the inserted position), the holding body 11 is released by pivoting about the bearing part 13 (more precisely about the vertical rotation axis a1 ( Figure 2b ) is deflected, so that the holding bracket 26 is disengaged from the ski boot and the push rod 16 is pressed towards the front end of the ski by the mechanically preloaded compression spring 17 at the same time, and the ski brake 3 is thus in the activated position via the brake support 7. The lateral release functional group is thus formed by the pressing device 36 (slider 24, compression spring 23, adjustment mechanism 25) and the rotatably mounted holding body 11.

[0108] Heel unit in the middle

[0109] Figure 3a to Figure 3c The heel unit is shown in an intermediate position. Figure 2a and Figure 3a As shown in the comparison, in order to make the heel unit enter the middle position from the entry position, the holding body 11 is relative to the guide plate 10 around the bearing component 13 ( Figure 3b )(i.e. around the vertical rotation axis a1( Figure 2b )) and resists compression spring 23 ( Figure 1 ) force, rotated 90° relative to the entry position, so that the compression spring 23 ( Figure 1 ) The stepped protrusion 24a ( Figure 1 ) is pressed against the lateral support surface 13a" ( Figure 1 Combination Figure 3a ), and the heel clip 2 is fixed to prevent accidental rotation (the second position of the slider 24, the second position of the retaining body 11). If the heel clip 2 moves from the entry position to the intermediate position, such as Figure 2c and Figure 3bAs shown in the comparison of FIG. 1 and FIG. 2 , the locking element 33 rotates in the same manner as the heel clip 2 because, as described above, the upper locking element end portion 33a is received in the slot-shaped receiving portion 32 on the lower side of the housing upper part 21 in a manner that prevents rotation. At the same time, due to the control protrusion 33b ( Figure 3b ) along the slide track 15a ( Figure 7 ) from the highest point 15a" ( Figure 7 , Fig. 9 ) is pushed to the lowest point 15a'( Figure 7 , Figure 8 ), so the height position of the locking element 33 relative to the other heel clip 2 changes, whereby the locking element 33 is rotated along the rotation axis a1 ( Figure 2 ) is pushed and in doing so is lowered relative to the heel clip 2 towards the plane of the ski, so that (as Figure 3b and Figure 3c The lower locking element end portion 33c protrudes into the groove 12d of the base part 12, and the sliding surface 33'c ( Figure 3c ) is aligned toward the front end of the snowboard and is parallel to and opposite to the sliding surface 16d' of the locking projection 16d. The locking element 33 is now in a locked position, which defines a second position of the locking element 33 relative to the plane of the snowboard. Figure 3a , Figure 3b ) remains in the active position.

[0110] The heel unit can be moved from the neutral position into the climbing position (see "Heel unit in the climbing position").

[0111] Furthermore, by appropriately rotating the holding body 11 , the heel unit can be re-entered from the intermediate position to the entry position.

[0112] Heel unit in climbing position

[0113] Figures 4a to 4c The heel unit is shown in a climbing position in which the ski boot is released in the heel area and the climbing aids 30, 31 ( Figure 4a , Figure 4b ) can be used in the expected manner. Figure 3a and Figure 4a As shown in the comparison, in order to make the heel unit from the middle position ( Figure 3a )Enter the climbing position( Figure 4a ), the ski brake 3 must be brought from the activated position into the inactivated position. This is achieved in particular by applying a suitable pressure on the brake pedal 5, preferably by the skier stepping on the brake pedal 5. Figure 3b and Figure 4bThe push rod 16 is pushed toward the end of the ski by the brake support 7 against the force of the compression spring 17, so that (as shown in the comparison of Figure 3c and Figure 4c As shown in the comparison of FIG. 1 and FIG. 2 ), the sliding surface 16d′ of the locking projection 16d hits the sliding surface 33c′ of the lower locking element end portion 33c, and the locking element 33 in the locked position is briefly lifted to the groove 12d against the force of the compression spring 34 and moves out of the groove 12d (thereby, the locking element 33 is briefly away from the plane of the snowboard). Once the locking projection 16d passes through the locking element 33 (as shown in FIG. 1 ), the locking element 33 is locked. Figure 4c As shown in the figure, the locking element 33 in the locking position is pressed downward by the compression spring 34, whereby the locking element end portion 33c reaches the groove 12d again, the locking protrusion 16d engages behind the lower locking element end portion 33c, and the ski brake 3 is thereby held in the inactive position.

[0114] The ski brake locking device already mentioned is thus formed by the mentioned slide guide, which is formed by a spring-loaded locking element 33 ( Figure 1 ) and the chute track 15a ( Figure 7 , Figure 8 ) and also by a spring-loaded push rod 16 ( Figure 1 ) is formed. Here, the spring-loaded push rod 16 is also the above-mentioned preload device 35 ( Figure 1 ) part.

[0115] To move the heel unit from the climbing position ( Figure 4a )Enter the entry position( Figure 2a ), the holding body 11 must be pivoted or pivoted back accordingly. Here, the slider 24 ( Figure 1 ) enters the first position from the second position, and the locking element 33 ( Figure 4c ) of the control protrusion 33b ( Figure 4c ) along the slide track 15a ( Figure 7 , Figure 8 ) from the lowest point 15a'( Figure 7 , Figure 8 ) is pushed to the highest point 15a" ( Figure 7 , Fig. 9 ), whereby the locking element 33 is lifted so that the lower locking element end portion 33c is removed from the groove 12d of the base member 12 ( Figure 2b , Figure 2c), so that the lower locking element end portion 33c no longer engages behind the blocking projection 16b. As a result, the locking element 33 is brought from its locking position into the release position. Once the locking element 33 is in the release position, the push rod 16 is moved toward the front end of the ski by the preloaded compression spring 17, so that the ski brake 3 is brought into the activated position ( Figure 2b , Figure 2c ).

[0116] Therefore, when the heel unit is in the climbing position, the ski brake locking device consisting of the slide guide (spring-loaded locking element 33 and slide track 15a) and the spring-loaded push rod 16 keeps the ski brake 3 in the inactive position, ensuring that the ski brake 3 enters the active position from the inactive position when the heel unit transitions from the climbing position to the entry position.

[0117] The invention is not restricted to the described exemplary embodiments.

[0118] The locking element 33 may have only a single control projection.

[0119] The pretensioning device 35 for the ski brake 3 can be formed by a torsion spring installed in the region of the ski brake 3, which pretensions the ski brake 3 into the activated position. Here, a pull rod is provided instead of the push rod 16, which is pulled toward the front end of the ski by the torsion spring via the brake support 7. Thus, a compression spring 17 is not required. When the ski brake 3 is actuated, the pull rod is pushed toward the end of the ski against the force of the torsion spring.

[0120] The compression spring 17 or torsion spring forms a brake adjustment spring which preloads the ski brake 3 into the activated position.

[0121] In summary, the push rod 16 or the pull rod represents an actuating lever belonging to the ski brake locking device, which is connected in an articulated manner to a part of the ski brake 3 and is also spring-loaded in the longitudinal direction of the ski and towards the front end of the ski.
