Definitions
- the invention relates to a heel unit for a touring ski binding, wherein the heel unit can be brought into an entry position, an intermediate position and a climbing position and wherein the heel unit comprises the following: a ski brake which can be brought into an active position and an inactive position, a heel jaw with a rotatable holding body for holding a ski boot, wherein the holding body has a vertical axis of rotation, and a ski brake lock, wherein the heel unit can be brought into the entry position and the intermediate position by pivoting the holding body in the active position of the ski brake, wherein in the intermediate position of the heel unit the ski brake is moved from the active position to the inactive position by actuating the ski brake and thus the heel unit is moved from the intermediate position to the climbing position, and wherein in the climbing position of the heel unit the ski brake is moved from the inactive position to the active position and thus the heel unit is moved into the entry position by rotating the holding body.
- Such a heel unit is known, for example, from AT 515 190 Bl.
- the heel unit comprises a heel jaw with a rotatable holding body (“binding body”), a ski brake (“brake arrangement”) and a ski brake lock.
- the ski brake can be brought into an inactive position (“braking position”) and an active position (“driving position”), with the ski brake being pre-tensioned into the active position, in particular by means of a conventional torsion spring.
- the ski brake lock is formed by a first control section located on the holding body and a second control section positioned on the ski brake.
- the heel unit can be moved into the active position of the ski brake by rotating the holding body into a Entry position (“downhill position”) and an intermediate position.
- the first control section points towards the tip of the ski and is located with one end section above the second control section.
- the first option is to operate the ski brake in the entry position of the heel unit so that the second control section is rotated about a transverse axis of rotation and approaches the plane of the ski, and to rotate the holding body when the ski brake is activated, whereby the first control section slides behind the second control section and blocks it (ski brake in the inactive position, heel unit in the ascent position).
- the intermediate position is “bypassed” with this procedure.
- a second possibility which is not described in the publication but is quite common among users, is to rotate the holding body starting from the heel unit in the entry position (heel unit in the intermediate position) and then actuate the ski brake, whereby the second control section carries out the described rotary movement and hits the second control section from above, whereby - with the appropriate amount of force - the second control section is pushed away together with the entire holding body in such a way that the first control section slides behind the second control section and blocks it (ski brake in the inactive position, heel unit in the ascent position). In the ascent position of the heel unit, the heel unit is brought back into the entry position by rotating the holding body.
- the heel unit comprises a ski brake, a heel jaw with a rotatable holding body and a ski brake lock with a hook.
- the heel jaw has a projecting cam with a curved running surface on the outside of its housing (“upper section 26”), the housing being supported by a aligned compression spring is pre-tensioned against a brake housing (“frame 28”) of the ski brake.
- the heel unit moves from the entry position to an intermediate position, the heel jaw is rotated against the force of the compression spring while being displaced backwards (i.e. away from the brake housing), with the curve running surface on the cam touching a projection on the brake housing.
- a hook of the ski brake lock that is operatively connected to the heel jaw is released (“activated”).
- the hook pivots about an axis running in a transverse direction, snaps into part of the ski brake so that it is held in the inactive position, while at the same time a compression spring acting on the hook is increasingly pre-tensioned.
- the heel piece is turned back, the hook is swung back by the compression spring acting on it, so that the ski brake is pressed into the active position via a torsion spring and the heel unit returns to the entry position.
- the heel unit comprises a ski brake with a plate-like brake bearing, a brake holder and a pre-tensioned brake bracket pivotably mounted on the brake bearing.
- the heel unit can be brought into an entry position (“holding configuration”), a climbing position (“walking configuration”) and an intermediate position.
- the brake bearing is mounted in a heel support so that it can be moved in the longitudinal direction of the ski and is pre-tensioned backwards in the active position of the ski brake, so that the brake bearing and the brake bracket are moved backwards.
- the heel jaw By turning the heel jaw by 180°, the heel unit is brought from the entry position to the intermediate position.
- the brake bar engages with the brake holder (ski brake in the inactive position, heel unit in the climbing position).
- heel unit moves from the climbing position back to the entry position, the brake bar is released from the brake holder so that the ski brake assumes the active position. Therefore, heel units for touring ski bindings are known in which the pivoting movement of the holding body is in functional interaction with the ski brake lock, which is preferable with regard to the simplest and most intuitive operation of the ski brake lock.
- the invention is therefore based on the object of ensuring a reliable and flawless functioning of the ski brake locking mechanism in a heel unit of the type mentioned at the beginning, in particular even under extreme weather conditions.
- the ski brake lock comprises a linearly displaceable, spring-loaded actuating rod connected to the ski brake and a guide rail located in the heel jaw, wherein the guide rail comprises a locking element aligned along the vertical axis of rotation of the holding body, rotating with the holding body and thereby displacing along the axis of rotation, spring-loaded in the direction of the ski plane, wherein the locking element assumes a release position in the entry position of the heel unit, in which the ski brake remains in the active position when actuated, and wherein the locking element assumes a locking position in the intermediate position of the heel unit, in which, when the ski brake is actuated, the actuating rod is brought into engagement 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, wherein when the heel unit moves from the climbing position to the entry position, the Locking element assumes the release position, whereby the actuating rod and the
- two components of the ski brake lock that can be engaged and disengaged namely the spring-loaded, specially mounted locking element and the spring-loaded actuating rod, form a "locking mechanism" located inside or in the area of the heel jaw, which is particularly well protected from external influences, such as mechanical stress or external influences that lead to icing. A reliable and flawless functioning of the ski brake lock is thus ensured.
- the actuating rod is spring-loaded in the longitudinal direction of the ski and in the direction of the ski tip, which supports a functionally reliable, compact design.
- a further embodiment which is advantageous in this respect is characterized in that the actuating rod is a push rod which is spring-loaded by means of a pre-tensioned compression spring or a pull rod which is spring-loaded by means of a torsion spring.
- the push rod and the compression spring belong to a pre-tensioning device that pre-tensions the ski brake into the active position or b) the torsion spring forms a pre-tensioning device that pre-tensions the ski brake into the active position.
- the push rod and the compression spring therefore perform a dual function, so that components and thus weight are saved.
- the actuating rod is a push rod which has a support projection located in its interior, in particular an annular one, on which the compression spring is supported.
- a further preferred embodiment consists in that the locking element and the actuating rod each have an inclined sliding surface which are aligned parallel to one another when the locking element is in the locking position and which meet when the heel unit moves from the intermediate position to the ascent position. This measure protects the ski brake lock particularly reliably against icing.
- actuating rod has a locking projection which is particularly triangular in cross-section, on which the sliding surface is formed and via which the actuating rod can be brought into engagement with the locking element.
- a further preferred embodiment is characterized in that the guide rail has a circular guide track in plan view with two diametrically opposed lowest points and two diametrically opposed highest points, and the locking element has two diametrically opposed control projections guided on the guide track. This ensures particularly reliable guidance of the locking element.
- a further preferred embodiment provides that the holding body is rotatable about the vertical axis of rotation via a combined axial-radial bearing formed in the heel jaw, which comprises a pressing device, whereby by rotating the holding body, it can be brought into a first position and into a second position, whereby the pressing device holds the holding body in the respective position and whereby the locking element is arranged in a groove formed in the area of the axial-radial bearing, along the vertical axis of rotation, whereby when the holding body is in the first position the locking element is in the locking position and when the holding body is in the second position the locking element is in the release position and whereby a part of the guide rail, in particular the guide rail, is in the through hole.
- a combined axial-radial bearing formed in the heel jaw which comprises a pressing device, whereby by rotating the holding body, it can be brought into a first position and into a second position, whereby the pressing device holds the holding body in the respective position and whereby the locking element is arranged in a groove formed in the area
- the axial-radial bearing and the pressing device comprise a common, linearly displaceable, spring-loaded slider and the axial-radial bearing further comprises a tower-shaped bearing part, wherein the slider and the tower-shaped bearing part interact in such a way that the holding body is rotatably mounted on the tower-shaped bearing part.
- a further preferred embodiment is characterized in that the heel piece comprises a guide plate which has a plate-shaped base part with a recess formed on the underside, running in the longitudinal direction of the ski, in which the actuating rod is guided, wherein the actuating rod preferably has two lateral, web-shaped guide projections running parallel to the plane of the ski, which are guided on web-shaped supports running parallel to one another, which protrude into the recess formed on the underside of the base part.
- the push rod is thus particularly well protected from external influences, in particular from icing.
- an advantageous variant consists in 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.
- a further preferred embodiment is characterized in that the actuating rod has a cross-shaped receptacle in which a brake support bolt of a brake support of the ski brake is mounted on the Brake support bolt is pivotably mounted. This ensures particularly advantageous mounting of the ski brake on a part of the ski brake lock (the operating rod).
- a further advantageous embodiment is one in which the holding body has a housing with a receptacle, in particular designed as a blind hole, preferably in the shape of an elongated hole, in which the locking element is accommodated in a manner secured against twisting, wherein the locking element in particular has a locking element end section corresponding to the receptacle and flattened on opposite sides parallel to one another.
- This embodiment also contributes to particularly good protection of the ski brake lock against icing.

- a slot-shaped opening 20a running perpendicular to the ski plane and aligned in the longitudinal extension of the housing lower part 20, so that the housing lower part 20 is designed like a frame.
- the guide projections 20b, 20c give the opening 20a a U-shaped opening section 20a' related to the outer circumference and a circular opening section 20a" when viewed from above.
- a threaded bore 20d (not visible in Fig. 11, see Fig. 2b, Fig. 2c) is formed which passes through the housing lower part 20 and is diametrically opposite the U-shaped opening section 20a'.
- the housing lower part 20 can be pushed from above onto the bearing part 13 (Fig. 1) over the circular opening section 20a" in order to assemble the holding body 11 (Fig. 2a).
- Fig. 1 in combination with Fig. 2b and Fig. 2c shows, in the area of the housing lower part 20 (numbered only in Fig. 1) there is a cuboid and block-like slide 24 (numbered only in Fig. 1), a compression spring 23 and an actuator 25, which together form a pressing device 36 (Fig. 1) for the holding body 11 (Fig. 2a).
- the slide 24 is spring-loaded by the compression spring 23, the slide 24 and the compression spring 23 being arranged in the housing lower part 20 (Fig. 1 in conjunction with Fig. 2b, Fig. 2c, housing lower part 20 and slide 24 only numbered in Fig. 1) and the actuator 25 is screwed into the threaded hole 20d (Fig. 2b, Fig. 2c).
- the slide 24 has on its opposite sides a stepped projection 24a and a blind hole 24b running at a constant distance from the ski plane (Fig. 2b) as well as on its other opposite sides straight and parallel web-shaped guide projections 24c running at a constant and consistent distance from the ski plane.
- the compression spring 23 is supported inside the blind hole 24b (Fig. 2b) and inside the actuator 25 (Fig. 2b, Fig. 2c), so that one spring abutment is formed by the blind hole 24b and the other spring abutment by the actuator 25.
- the slide 24 is via its guide projections 24c (Fig. 1) and the guide projections 20b, 20c (Fig.
- the holding body 11 (Fig. 2a) is rotatable about the bearing part 13 and therefore about a vertical axis of rotation ai (Fig. 2b) running in particular centrally through the through hole 14 (Fig. 1) due to the described mounting of the housing lower part 20 (Fig. 1) on the bearing part 13 (Fig. 1).
- the vertical axis of rotation ai is perpendicular to the ski plane.
- the bearing part 13 forms together with the pressing device 36 (Fig. 1) a combined axial-radial bearing, which allows the pivoting movement of the holding body 11 (Fig. 2a) relative to the guide plate 10 (Fig. 1, Fig. 2a).
- the upper housing part 21 has on its upper side an edge-side holding element 21a located at one end region, two central holding elements 21b that are spaced at the same distance from this and lie opposite one another (only one can be seen in Fig. 2a) and a circular segment-like, edge-side holding element 21c.
- a holding bracket 26 in the form of a U-bracket is guided around the holding elements 21a, 21b, 21c, which contacts these and is pressed against them due to its design, which has two free ends for receiving a correspondingly designed ski boot and is placed in the region of its curved section against the circular segment-like, edge-side holding element 21c, the holding elements 21a, 21b projecting over the holding bracket 26 on its upper side like a clamp (Fig. 2a).
- the retaining bracket 26 is secured against being pushed down from the upper housing part 21 by means of a securing element 27.
- a climbing aid spring 28 is located between the middle retaining elements 21b, which surrounds one middle retaining element 21b in a U-shape.
- a bolt 29 is arranged, which is guided between the middle retaining elements 21b and attached to the edge retaining elements 21a, 21c, and on which two climbing aids 30, 31 are pivotably mounted.
- the climbing aids 30, 31 act with the climbing aid spring 28 during pivoting movement in such a way that that the climbing aid spring 28 is pressed downwards and thus the climbing aids 30, 31 are held in position.
- the upper housing part 21 has a receptacle 32 (see Fig. 4c) extending from its underside, running perpendicular to the ski plane, located in a straight extension of the through hole 14 (Fig. 1), designed as a blind hole, with a rectangular or elongated hole-shaped cross section parallel to the ski plane.
- a pin-shaped, elongated locking element 33 which is spring-loaded in the direction of the ski plane, is positioned inside the housing 19 (Fig. 1) in the through hole 14 passing through the bearing part 13 and the base part 12.
- the locking element 33 is therefore aligned along the vertical axis of rotation ai (Fig. 2b), is located in the heel jaw 2 (Fig. 2b, Fig. 2c) and is further away from the ski plane than the push rod 16 (Fig. 1, Fig. 2b, Fig. 2c).
- the locking element 33 has an upper locking element end section 33a which is flattened parallel to one another on opposite sides and which is received by the receptacle 32 (Fig. 2b, Fig. 2c, Fig. 2d) on the underside of the upper housing part 21 in a manner secured against twisting, two diametrically opposed control projections 33b (one can be seen), via which the locking element 33 rests on the guide track 15a of the guide projection 15 inside the through hole 14 (Fig. 2d), and a lower locking element end section 33c located in the hole end section 14a (cf. Fig. 2d).
- the upper locking element end section 33a has - due to its flattening - two flat surfaces 33a' aligned parallel to one another.
- a compression spring 34 is pushed onto the locking element 33 from above, with one spring abutment being supported by the control projections 33b (cf. Fig. 2d) and the other spring abutment is formed at the outlet of the receptacle 32 (see Fig. 2b to Fig. 2d).
- the compression spring 34 presses the locking element 33 in the direction of the ski plane.
- the spring-loaded locking element 33 forms a sliding guide together with the sliding track 15a (Fig. 7).
- the heel unit can assume an entry position, a downhill position, an intermediate position and an ascent position.
- the ski brake 3 can assume an active position and an inactive position.
- the holding body 11 and the slider 24 can assume mutually corresponding first positions and mutually corresponding second positions.
- the heel unit includes a ski brake lock and a side release function group.
- the compression spring 17 presses the push rod 16 in the direction of the ski tip, whereby the brake pedal 5 is pressed upwards via the brake support 7 and the free ends of the brake levers 6 are pressed downwards, so that the ski brake 3 is in the active position mentioned, i.e. is pre-tensioned into this by means of the pre-tensioning device 35 (Fig. 1). If the ski brake 3 is in the active position, the brake levers 6 protrude from the ski plane in the known manner and grip the ground The compression spring 23 presses the slider 24 (Fig. 1) in the direction of the bearing part 13, whereby the offset projection 24a of the slider 24 (Fig.
- the ski boot When stepping into the heel unit, the ski boot is brought into engagement with the retaining bracket 26 of the holding body 11 in a known manner, with the brake levers 6 being moved essentially into the plane of the ski via the brake pedal 5, i.e. coming to rest to the side of the ski, so that the ski brake 3 is in the inactive position. If the ski brake 3 is in the inactive position, the brake levers 6 are therefore to the side of the ski and thus do not engage the ground.
- the push rod 16 which is linked to the brake pedal 5 via the brake support bolt 7c of the brake support 7, is pressed against the force of the compression spring 17 towards the end of the ski.
- the heel unit After stepping in, the heel unit is in the downhill position, the ski brake 3 is in the inactive position, the locking element 33 remains in the release position and the slider 24 and the holding body 11 remain in their first positions.
- the holding body 11 is deflected by pivoting about the bearing part 13, more precisely about the vertical axis of rotation ai (Fig. 2b), so that the holding bracket 26 is disengaged from the ski boot and essentially At the same time, the push rod 16 is pressed in the direction of the ski tip by the mechanically pre-tensioned compression spring 17 and the ski brake 3 thereby assumes the active position via the brake support 7.
- the side release functional group is thus formed by the pressing device 36 (slider 24, compression spring 23, actuator 25) and the rotatably mounted holding body 11.
- Fig. 3a to Fig. 3c show the heel unit in the intermediate position.
- the holding body 11 in order to move the heel unit from the entry position to the intermediate position, the holding body 11 is to be rotated relative to the entry position relative to the guide plate 10 by 90° about the bearing part 13 (Fig. 3b), i.e. about the vertical axis of rotation ai (Fig. 2b), and against the force of the compression spring 23 (Fig. 1) in such a way that the compression spring 23 (Fig. 1) presses the offset projection 24a of the slider 24 (Fig. 1) against the lateral support surface 13a" (Fig. 1 in conjunction with Fig.
- the heel jaw 2 is secured against unintentional twisting (second position of the slider 24, second position of the holding body 11).
- the locking element 33 is rotated in a consistent manner to the heel piece 2 - as a comparison of Fig. 2c with Fig. 3b shows - since, as already explained - the upper locking element end section 33a is received by the slot-shaped receptacle 32 on the underside of the upper housing part 21 in a manner secured against twisting.
- the locking element 33 is changed in its height position relative to the rest of the heel piece 2, since the control projections 33b (Fig. 3b) are pushed along the guide track 15a (Fig.
- the locking element 33 in the locking position is pressed downwards by the compression spring 34, whereby the locking element end section 33c returns to the groove 12d, the locking projection 16d engages behind the lower locking element end section 33c and the ski brake 3 is thereby held in the inactive position.
- the ski brake locking mechanism already mentioned is therefore formed by the aforementioned guide rail consisting of the spring-loaded locking element 33 (Fig. 1) and guide rail 15a (Fig. 7, Fig. 8) as well as the spring-loaded push rod 16 (Fig. 1).
- the spring-loaded push rod 16 is simultaneously part of the aforementioned pre-tensioning device 35 (Fig. 1).
- the holding body 11 In order to move the heel unit from the ascent position (Fig. 4a) to the entry position (Fig. 2a), the holding body 11 must be pivoted or pivoted back accordingly.
- the slider 24 (Fig. 1) is moved from the second position to the first position and the control projections 33b (Fig. 4c) of the locking element 33 (Fig. 4c) are pushed along the guide track 15a (Fig. 7, Fig.
- the ski brake locking mechanism from the guide rail (from the spring-loaded locking element 33 and the guide rail 15a) and the spring-loaded push rod 16 thus holds the ski brake 3 in the inactive position when the heel unit is in the climbing position and ensures that the ski brake 3 is moved from the inactive position to the active position when the heel unit moves from the climbing position to the entry position.
- the locking element 33 can have only a single control projection.
- the pre-tensioning device 35 for the ski brake 3 can be formed by a torsion spring installed in the area of the ski brake 3, which pre-tensions the ski brake 3 into the active position.
- a pull rod is provided, which is pulled by the torsion spring via the brake support 7 in the direction of the ski tip.
- the compression spring 17 is thus dispensed with.
- the pull rod is pushed against the force of the torsion spring in the direction of the ski end.
- the compression spring 17 or the torsion spring form a brake setting spring that preloads the ski brake 3 into the active position.
- the push rod 16 or the pull rod each represent, in a generalized form, an actuating rod belonging to the ski brake locking mechanism, which is connected in an articulated manner to a part of the ski brake 3 and which is also spring-loaded in the longitudinal direction of the ski and in the direction of the ski tip.
