EP3323476B1 - Touring binding for mounting to a glide board - Google Patents

Description

The present invention relates to a front unit of a touring binding for mounting on a gliding board, wherein a release path of the front unit can be blocked by a blocking section in order to prevent a touring shoe from leaving a bearing element.
The publication DE 10 2009 059 968 A1 discloses such a front unit, the front unit being essentially U-shaped and the release path running along upwardly open U-shaped or V-shaped grooves. This release path can be closed by lugs held on swivel levers or linearly guided pins. However, if such a front unit freezes over, ice can form in the swivel area of the swivel levers or in the path of movement of the pins, which makes it difficult or even impossible to get in and out of the front unit, since the mechanics used are susceptible to environmental influences.
The WO 2011/015234 A1 , the CH 47443 A and the WO 2015/159163 A1 also disclose front units for ski bindings according to the preamble of claim 1.
The object of the present invention is to provide a front unit of a touring binding with improved functionality in the presence of negative environmental influences.
This object is achieved according to the invention by a front unit of a touring binding according to claim 1. It is preferred that the transverse axis about which the touring shoe is pivoted and the axis of rotation of the blocking section run transversely to a longitudinal axis of the sliding board and parallel to a sliding board plane / surface. Since the axis of rotation of the touring shoe has the same direction as the axis of rotation of the blocking section, the blocking section can move around the bearing element or together with the bearing element. As a result, the bearing element does not hinder a rotational movement of the Blocking section, so that a bearing surface of the blocking section can be covered completely, whereby a dirt-insensitive bearing can be provided for the blocking section. The bearing element can be designed as a bush or bearing bush for rotation in the bearing arrangement. The bearing element can be designed to hold a counter bearing section of the touring shoe in an opening which extends along the axis of rotation of the blocking section. The bearing element can be mounted in an insert or an insertion bush in the bearing arrangement. A spatial structure which can define the release path and / or an entry path is preferably provided in the insert or the insertion bushing.

In the front unit of the touring binding, the blocking section on the bearing element can be integrally formed and the bearing element can be in the transition from the neutral state to the

Blocked state to perform a rotational movement around an axis of rotation of the bearing element running transverse to a longitudinal axis of the sliding board. If the blocking section on the bearing element is designed for common rotation, the bearing of the bearing element, which is stable because it is designed for wearing the shoe, is also the bearing of the blocking section, as a result of which the bearing has a double function and, due to the stability of the bearing, there is a transition between the blocked state and the neutral state is particularly susceptible to interference.

It is also possible that the blocking section extends essentially in one direction along the axis of rotation of the bearing element, and / or wherein the front unit further comprises an entry contour and / or a release contour and / or an exit contour, which is formed at least in sections on the bearing element , and wherein preferably the entry contour and / or the release contour and / or the exit contour is formed as a recess essentially in one direction along the axis of rotation of the bearing element. If an entry contour and / or a release contour and / or an exit contour is provided on the bearing element, the bearing element has a multiplicity of functions and can thus reduce the complexity of the entire front unit, since additional individual parts provided for implementing these functions are avoided. If the blocking section essentially extends in one direction along the axis of rotation of the bearing element and if the entry contour and / or the release contour and / or the exit contour is designed as a recess essentially along this direction, these elements can become caught during rotation of the bearing element can be prevented during rotation. In particular, the exit contour is set up to allow the touring shoe to come loose from the front unit, for example during a rotational movement or swivel movement.

It is preferred that the front unit is set up to assume an entry state and / or a departure state and / or an exit state; the bearing element executing a rotational movement about a rotation axis of the bearing element running transversely to a longitudinal axis of the sliding board, in the event of a transition between the blocked state and at least one of the neutral state, the entry state, the departure state and the exit state and / or the transition between the departure state and the exit state. As a result, the transition between the individual states of the front unit is made possible by a single type of movement of the bearing element, so that complex and fault-prone mechanics can be dispensed with. In particular, the front unit can comprise an entry contour and / or a release contour and / or an exit contour, which is formed at least in sections on the bearing element.

In a particularly preferred embodiment, the release path runs essentially parallel to the longitudinal axis of the gliding board. In addition, the release path can run essentially parallel to a sliding board plane. In this case, it is possible to achieve a particularly secure gliding board binding with the front unit, since the front unit supports a rotary release of the touring shoe about an axis that is essentially perpendicular to the gliding board level (Z release).

Furthermore, it can be considered that the bearing element is set up to receive a counter bearing section of the touring shoe, preferably protruding from a front section of the touring shoe. Snow and ice preferentially accumulate on the touring shoe before using the gliding board, but can be removed from the anvil section with a protruding counter bearing section particularly easily compared to a depression provided on the touring shoe as a counter bearing section, which improves the functionality and Front unit security improved. The counter bearing sections of the touring shoe can be left and right pins which protrude laterally on the front of the shoe in opposite directions. It is also possible that an entry path is defined on the bearing arrangement and is set up to guide the counter-bearing section of the touring shoe into the bearing element, the entry path essentially running perpendicular to the plane of the sliding board when the front unit is in the entry position exerted perpendicular to the gliding board level on the gliding board so that the sliding board does not slip when entering the front unit.

In a further preferred embodiment of the invention, the front unit has a holding configuration and an exit configuration, the bearing arrangement and / or the bearing element executing a movement in the forward direction when the front unit changes from a holding configuration to an exit configuration. This allows the front unit to interact with a heel unit of a touring binding such that the heel unit does not have to have a stable opening position (see heel unit off DE 10 2010 043 880 A1 ), because during the transition of the front unit between a holding configuration and an exit configuration due to the offset of the bearing arrangement and / or the bearing element, a touring shoe can be pulled out of the heel unit (during the transition to the exit configuration) or pushed into the heel unit. In particular, the front unit of the Tour binding can be set up to hold the touring shoe on the front unit during the transition of the front unit from the holding configuration to the exit configuration, in which the bearing arrangement and / or the bearing element executes the movement in the forward direction. As a result, during the movement of the bearing element in the forward direction, the touring shoe is pulled out of the heel unit which is usually present, and the touring shoe can subsequently be released from the front unit without hindrance by the heel unit, and thus particularly conveniently and safely, for example by a lateral rotation.

It is preferred that the bearing arrangement executes a pivoting movement, preferably about a pivoting axis running transversely to the longitudinal axis of the gliding board, when the front unit changes between the holding configuration and the exit configuration. Swivel arrangements can be particularly simple and insensitive to dirt, e.g. B. be formed by using particularly dirt-resistant rotary bearings.

In a particularly preferred embodiment, the front unit further comprises a locking arrangement which is set up to prevent a transition from the holding configuration to the exit configuration in a locking state and to permit a transition from the holding configuration to the exit configuration in a locking position. This increases the safety and functionality of the front unit by preventing an unwanted transition from the holding configuration to the exit configuration.

In particular, it is contemplated that the locking arrangement comprises: a slide guide, preferably with a slide stop, a slide, a first support element, a second support element, a first pivot axis, a second pivot axis, a third pivot axis, a Lever with a first stop element and a second stop element; wherein preferably the first, second and third pivot axes each run parallel to one another, the first pivot axis being arranged stationary with respect to the slide guide and the third pivot axis being arranged stationary with respect to the carriage, the first carrier element connecting the first and second pivot axes to one another and in each case pivotably supporting them and the second carrier element connects the second and third pivot axes to one another and each is pivotally mounted, the lever being pivotably mounted on the second pivot axis, the first stop element on the second carrier element being pivoted from a rest position in a first direction by a first angular amount attacks, wherein when the lever is pivoted in the first direction from the rest position by a second angular amount, which is greater than the first angular amount, the second stop element engages the first carrier element. Such an arrangement is in the locked state in a stable state, so that the transition from the holding configuration to the exit configuration can be prevented particularly reliably.

In a further preferred embodiment of the invention, the bearing element is set up to hold a touring shoe on a counter bearing section of the touring shoe pivotably on the front unit about a transverse axis running transversely to a longitudinal axis of the gliding board, with a transition of the front unit between a holding configuration and an exit configuration of the front unit or a transition of the front unit between a neutral state and a blocked state of the front unit is effected by a transmission of tensile force via at least one flexible element, preferably a rope, a chain, a flexible band or a flexible rod. In particular, a transition from Front unit between two states of a release state, an entry state and an exit state of the front unit can be effected by a transmission of traction via the flexible element. A transmission of tensile force via at least one flexible element has essentially no restrictions in the presence of snow and / or ice on the front unit, since the contact surface of the contaminants on a flexible element is predominantly small, and these contaminants can then simply be stripped off during a transmission of tensile force or flake off.

In a particularly preferred embodiment, the front unit further comprises: a pivotable lever, a first engagement section designed to rotate together with the lever, a second engagement section designed to rotate together with the bearing element, the first engagement section being shared with the second engagement section via the flexible element Rotation is connected, and wherein the flexible element implements a pivoting of the lever in the rotational movement of the bearing element by the tensile force transmission. With such an arrangement, the combination of the transmission of tensile force via the flexible element with the provision of rotation bearings that are insensitive to dirt permits a further increase in the dirt resistance of the front unit.

In a further aspect, the invention provides a system comprising a front unit for a touring binding and a touring shoe, the touring shoe having two counter bearing sections, particularly preferably protrusions or pins, laterally protruding laterally from a front section of a sole of the touring shoe, at least of which protrusions or pins one is designed to be held on the bearing element of the front unit so as to be pivotable on the front unit about the transverse axis running transversely to the longitudinal axis of the gliding board, with one position of the projections being relative is immovable to each other and relative to the sole of the touring shoe. The advantages of the front unit described above are also transferred to such a system, with outstanding counter-bearing sections being particularly easy to remove from ice and snow. The fixed arrangement of the counter bearing sections makes it possible to dispense with a movable bearing mechanism for the counter bearing sections, which in turn increases the dirt resistance of the system. The counter bearing sections can protrude in particular in opposite directions.

With regard to the advantages of rotary bearings / swivel bearings compared to, for example, linear bearings, it should be noted that in a linear bearing a slide can never cover the entire linear bearing, but there must be a certain free path for the movement of the slide, so that it is difficult to to secure this clear path against the ingress of dirt. In the case of rotary bearings / swivel bearings, however, it is possible for the inner bearing surface of the bearing to be completely surrounded by an outer bearing surface of the bearing, so that the penetration of dirt is particularly well prevented. The seal along the axis of rotation of the bearing can be provided solely by a good fit of the rotary elements, but also special sealing elements, such as panels on the front ends of the bearing or sealing rings can also be provided.

The following definitions can be used in the application: In a blocked state of the front unit, a counter bearing section of the touring shoe, in particular along a release path, is prevented from leaving the front unit, while in a neutral state it can leave the front unit. The blocking state and / or neutral state can be dependent on an angular position of the bearing element in the bearing arrangement or on its change. In a holding configuration, the front unit is in a configuration that is suitable holding the shoe on the front unit and in an exit configuration, the front unit is in a configuration in which an exit from the front unit is made possible and / or favored. Taking up the holding configuration and / or the exit configuration may depend on an angular position of the bearing arrangement with respect to a base element of the front unit, or on its change. In a release state, the front unit is set up to release a counter bearing section of the touring shoe from the front unit, in particular from the bearing element, for example in the event of a safety release. In an entry-level state, the front unit is set up to receive a counter bearing section of the touring shoe in the front unit, in particular in the bearing element. In an exit state, the front unit is set up to allow and / or to favor exiting the front unit. Adopting the release state, the entry state and / or the exit state can depend on an angular position of the bearing element in the bearing arrangement or on its change.

Further preferred embodiments of the invention are specified in subclaims 3 to 9.

The embodiments of the front units described below are essentially symmetrical with respect to a central plane of the front unit, in the left / right direction, so that the following description, unless stated otherwise, focuses on the description of one of the sides and the embodiments indicate this corresponding left or right element not described or the structure not described. Furthermore, it can be seen from the figures that parts of the front unit are only present in spite of the essentially symmetrical structure, e.g. B. Lever.

Insofar as reference is made in this application with regard to directions, levels and the like, an operationally mounted front unit of a touring binding is to be assumed here, so that the directions (front, rear, left, right) or levels of the sliding board in the amount state change transfer the front unit of the touring binding. Furthermore, axes and pivot axes can be designed as shafts in the context of this application.

First embodiment

The Figure 1 shows the front unit 2 of a touring binding according to a first embodiment, with a bearing arrangement 4 with a first, left bearing element 6 with a left opening 8 and a second right bearing element 10 and a right opening 12. Each of the bearing elements is via the openings 8 and 12, respectively 6 and 10 are configured to receive a counter bearing section of a touring shoe, which preferably protrudes from a front section of the touring shoe, and thus to hold the touring shoe on the front unit 2 pivotably about a transverse axis Q running transversely to a longitudinal axis of the gliding board. The transverse axis Q can run transversely to the longitudinal axis of the sliding board and parallel to a sliding board plane / sliding board surface.

The bearing arrangement 4 is preferably U-shaped and can comprise particularly light material, such as aluminum, titanium or a carbon fiber composite. In order to increase the rigidity of the bearing arrangement 4, it can have a stiffening web 14, which can connect legs 4l, 4r of the U-shaped bearing arrangement 4, preferably spaced apart from a base 16 of the U-shaped bearing arrangement. The bottom 16 can have openings 18 for mounting the front unit of the touring binding. Integral with or separately from the bearing arrangement 4, the front unit 2 can have a lever bracket 20 with a lever 22.

The front unit 2 is particularly suitable for a touring shoe as in the document DE 10 2009 059 968 A1 with outstanding / outstanding counter bearing sections, in particular bearing pins, to hold the front unit pivotably. In order to enable the touring shoe to be released from the front unit 2 by a safety release (Z-release) in the presence of excessive lateral forces which attempt to turn the touring shoe out of the front unit 2, it is preferred that the counter-bearing sections against a spring force or Similar things can be moved into the touring shoe. A corresponding arrangement is e.g. B. in the European patent application EP 2 946 818 A1 described.

In order to allow such a Z-release to take place in a defined manner, a release path 24 is defined on the bearing arrangement 4, preferably on each of the U-shaped legs 4l, 4r. The release path 24 can be defined by a spatial structure in the bearing arrangement 4, for example this can be an interruption 26 of a collar 28 or a recess 30 which enables and / or guides a movement of the counter bearing sections of the touring shoe. The release path 24 preferably runs essentially parallel to a sliding board plane. Furthermore, an entry path 32 can be defined on the bearing arrangement 4, which is preferably defined via a recess 34, along which a counter bearing section of the touring shoe can get into the front unit 2 of the touring binding, for example it can slide, in order to be held on the front unit 2. The recess 34 or its bottom section 34a can run essentially perpendicular to the axis Q. The entry path 32 preferably runs perpendicular to the plane of the gliding board. The release path 24 and the entry path 32 are preferably defined in an insert 36 of the bearing arrangement 4 and preferably formed over a respective recess 34 or 30, as a result of which the material of the insert 36, for example stainless steel or a particularly hard aluminum alloy, can be adapted to the load caused by the counter bearing sections of the touring shoe. The insert 36 can have a protrusion 48 which protrudes in the circumferential direction, which in an assembled state engages in a corresponding recess 45 in a leg 4l, 4r of the U-shaped bearing arrangement 4 and thus the angular position and the depth of penetration in one direction of the insert 36 in the Bearing arrangement defined. The recess 34 is preferably formed in the projection 48. The insert 36 can be pressed into an opening 47 in one of the legs 4l, 4r of the U-shaped bearing arrangement 4.

The insert 36 is preferably supported in a direction along the axis Q with respect to one of the legs 4l, 4r by a step 50 of the insert 36 which strikes the material of the leg 4l or 4r. The collar 28 is preferably formed on the insert 36. The collar 28 can prevent movement of the counter bearing section out of the bearing element in a direction essentially downwards and / or a direction essentially forward.

Each of the bearing elements 6 and 10 can be designed to be rotatable about the axis of rotation Q running transversely to a longitudinal axis of the sliding board, about which a touring shoe can be pivotably held on the front unit. Such a bearing element is preferably designed as a bush or bearing bush 38, which in turn can be rotatably mounted in the insert 36 via a bearing 40. The bearing 40, which is preferably designed as a sliding bearing, can be protected against environmental influences such as moisture or dust by seals (not shown). Bearing 40 can also be designed as a ball bearing (not shown).

In the first embodiment, the front unit 2 comprises a blocking section 42, which can preferably be formed on the bearing element 6 or 10, in particular integrally. In the first embodiment, the blocking section 42 is integrally formed on the bush 38 and preferably comprises an inner surface 44 which extends essentially around the axis Q, wherein in the area of the blocking section 42 a roof 46 can be formed on the outer circumference of the bush 38, which, like will be described later, can prevent entry into the front unit 2. In particular, the angular range (with respect to a rotation about the axis Q) that the roof 46 covers can be smaller than the angular range (with respect to a rotation about the axis Q) that the inner surface 44 covers. The blocking section 42 can be regarded as a projection or collar which has at least one interruption in the circumferential direction and preferably extends along the axis of rotation Q of the bearing element. The opening 8 or 12 is preferably formed essentially along the axis of rotation of the bearing element, here the bush 38, and is designed to receive a counter bearing section of the touring shoe, so that the pivot axis of the touring shoe in the front unit 2 can coincide with the axis of rotation of the bearing element. The bearing element, here the bush 38, is set up to rotate about the pivot axis of the touring shoe in the front unit 302.

An entry contour 52 and / or a release contour 54 and / or exit contour 74 can be formed on the socket 38, each of the contours 52, 54 and 74 as a recess, essentially along a direction predetermined by the axis Q, with respect to a plane L, which can define one end of the bush 38, can be formed. The entry contour 52 is preferably formed in the circumferential direction of the bush 38 adjacent to the trigger contour 54.

A groove 56 can be formed on the bushing 38 as an engagement section for receiving a flexible element 58, for example a rope or a flexible band or a chain. It is also possible to provide a toothed wheel at this point for receiving a chain or to provide only two partial grooves, at the ends of which a flexible rod can be fastened for transmitting tensile force. On the lever 22, a further engagement section is provided as a corresponding counterpart, depending on the design of the flexible element 58, in the case of a rope, for. B. a roller element 60 with a groove, wherein the roller element 60 can be designed to rotate together with the lever 22. The flexible element 58 preferably connects the groove 56 to the groove of the roller element 60, whereby a rotation of the roller element 60, and thus of the lever 22, is preferably coupled to a rotation of the bush 38. Two roller elements 60 with grooves can be provided for use with two flexible elements. The Figures 2a to 2c show partial sections, the section plane passing through the roller element 60 arranged on the right and being parallel to a middle plane of the sliding board.

The lever 22 and the lever carrier 20 are preferably part of an indexing device 62 of the front unit, which can latch the lever 22 in a plurality of positions. Preferably, three recesses 64-68 are formed on the roller element 60, which can interact with a flexible or spring-mounted projection 70 of the lever support 20. Alternatively, a depression can be formed in the lever carrier 20 and three protrusions, preferably flexibly or resiliently mounted, can be formed on the roller element 60.

The entry contour 52 is preferably designed such that when the recess 66 interacts with the projection 70, it is aligned with the entry path 32, in particular the recess 34. The front unit is then in an entry-level state. The entry contour 52 can be used as an entry slope (A surface which is preferably inclined with respect to the axis Q and preferably points outwards with respect to the axis Q), via which, in the entry state, a counter bearing section of the touring shoe guided through the entry path 32 can slide into the opening 8 or 12, here the counter bearing section of the touring shoe penetrate into the touring shoe, preferably against a restoring force. An entry contour, here the entry contour 52, can also be designed as a rounding, a notch, a guide rail or the like instead of as an entry slope.

If the recess 66 interacts with the projection 70, the release contour 54 is aligned with the release path 24, so that the front unit 2 is in a departure state, which can preferably coincide with the entry state. In the departure state, the counter bearing portion of the touring shoe can slide out of the bearing element, preferably against a restoring force provided by the touring shoe, out of the front unit along the release contour 54 when a lateral force occurs. The trigger contour 54 is preferably designed as a trigger slope (a surface which is preferably inclined with respect to the axis Q and preferably faces inwards with respect to the axis Q). If another intermediate angle is provided between the trigger contour 54 and the entry contour 52, the indexing device can be supplemented by a corresponding further recess on the roller element 60, so that the bush 38 can assume a separate angular position for the departure state.

If the lever 22 is pivoted about an axis 72 of the lever 22 such that the recess 68 interacts with the projection 70, the bush 38 is rotated such that the exit contour 74 is essentially flush with the entry path 32, in particular the recess 34, whereby the front unit 2 is in an exit state. Preferably the exit contour 74 is provided with a bottom section 82 which extends essentially perpendicular to the axis Q and has a position along the axis Q such that when the counter bearing section moves out of the opening 8 or 12, the counter bearing section preferably does not have any resistance due to the exit contour 74 is brought towards.

If the lever 22 is now pivoted about the axis 72 in such a way that the recess 64 interacts with the projection 70, the inner surface 44 of the blocking section 42 is blocked, in particular the partial surface 44a, the release path 24 and the front unit 2 is in a blocked state. In the blocked state, the front unit 2 is set up so that the touring shoe can pivot about the axis Q and is held on the front unit 2, preferably in a non-detachable manner, as is customary when climbing in touring with a pin binding. In the blocked state, the roof 46, which preferably has an outer surface parallel to the axis Q (externally with respect to the axis Q), is aligned essentially flush with the entry path 32 or the recess 34, so that a touring shoe enters the front unit in the blocked state is blocked.

In the boarding state and the departure state, the blocking section 42 does not block the release path 24 and permits movement of the counter bearing section along the release path 24, so that the front unit 2 is in a neutral state.

The bearing 40 preferably has a first guide groove 76 formed on the bush 38 and a second guide groove 78 formed in the insert 36 in the radial direction. The bearing 40 can then be assembled by inserting the bush 38 into the insert 36, which is then inserted into the opening 47, with a rod / rod 80 through an opening 84 in the leg 4l or 4r in both guide grooves 76 and 78 is inserted. As a result, both a position of the insert 36 and the socket 38 along the axis Q can be defined.

Alternatively, the indexing device 62 can be dispensed with and a separate indexing device with a manual rotating device of the respective bearing element can be provided on each of the bearing elements. The manual rotating device can be designed as a radially projecting section on the bush 38 (for an example of this, see the design of the anti-slip device 368 of the fourth embodiment). In order to provide an indexing device on a bearing element, a plurality of recesses can be formed, for example, on the bush 38, in particular instead of or next to the groove 56, and on the legs 4l, 4r of the U-shaped bearing arrangement 4, in which the respective bush 38 a projection can be formed flexibly or resiliently, which can engage in the recesses on the bushing 38 in analogy to the interaction of the projection 70 with the recesses 64 to 68 of the indexing device 62 in order to hold the bushing 38 in a desired position . In this case, in order to turn the bush 38 into a further desired position, a torque can be overcome so that the projection is pressed out of the recess on the bush 38 and, when the next desired position is reached, engage again in another recess on the bush 38 can. Just as with the indexing device 62, the recesses on the bush 38 can be selected such that the flexible or resilient projection on the respective leg 4l, 4r only engages in the next recess on the bush 38 when a desired condition or a desired one Front unit configuration is reached.

Second embodiment

Only the differences from the first embodiment are described below. Elements which correspond essentially to those in the first embodiment are provided with 100 increased reference numerals compared to elements of the first embodiment, apart from reference numerals for axes.

A front unit of a touring binding of the second embodiment differs from the front unit 2 of the first embodiment in the design of the bushing and the insert. The bushing 138 of the second embodiment has in particular a blocking section 142 with an inner surface 144 and a roof 146, a triggering contour 154 and / or an entry contour 152, the triggering contour 154 preferably essentially on a side of the bushing 138 opposite a center of the blocking section 142 is trained. The trigger contour 154 is also the exit contour of the bush 138, so that an indexing device of the front unit of the second embodiment is adapted to corresponding angular positions. Two entry contours 152 can be provided so that bushing 138 can be used on the right and left sides of the front unit.

The insert 136 of the second embodiment has a recess 134, the bottom 134a of which is arranged at an acute angle with respect to the axis Q and points outwards with respect to the axis Q.

It can be seen in Figure 9 that the bushing 138 of the second embodiment has a blocking section 142 which is formed by a circumferential section of the bushing 138 projecting in the axial direction on the shoe side. The release contour 154, on the other hand, forms a release section assigned to the release path, which is a circumferential section of the bush 138 that is axially recessed relative to the block section 142. In particular, the release section (the release contour 154) is provided by a section which runs obliquely to the axis of rotation, in particular in formed at an angle between approximately 30 ° and approximately 60 ° to the axis of rotation of the release inclined surface, which faces the axis of rotation. During the release process, the pin provided on the shoe can slide on the inclined surface of the release contour 154 and thus leave the socket, so that the shoe is released.

Furthermore, the bush 138 of the second embodiment has the entry contour 152, which is formed by an entry inclined surface, the entry inclined surface being inclined to the axis of rotation, here in particular at an angle between approximately 30 ° and approximately 60 ° to the axis of rotation, and facing away from the axis of rotation . Accordingly, when entering the binding, a pin provided on the shoe can slide along the sloping entry surface of the entry contour 152 and enter the socket 138.

The inclined surfaces of the release contour 154 and the entry contour 152 interact particularly advantageously with pins which are axially movable on the shoe and held in a prestressed manner by a spring. Alternatively or additionally, the bushing or the bearing arrangement of the binding can be movable in the axial direction.

ausführen, wobei 20° ≤ β ≤ 70° und n ≥ 0 eine natürliche Zahl ist.In Figure 9 it can also be seen that in the second embodiment the blocking section 142, the release contour 154 and the entry contour 152 on the bush 138 are formed on three circumferential sections of the bush 138 which are offset in the circumferential direction. The socket 138 can thus be adjusted in at least three different rotational positions in order to implement the different functions, entry, walking position and departure position. The bushing 138 can each make a rotational movement through an angle during a transition between the functions $$\alpha =\beta +n\ast 90°$$

execute, where 20 ° ≤ β ≤ 70 ° and n ≥ 0 is a natural number.

Third embodiment

Only the differences from the first embodiment are described below. Elements which correspond essentially to those in the first embodiment are provided with 200 increased reference numerals compared to elements of the first embodiment, apart from reference numerals for axes. The front unit of the third embodiment for a touring binding is particularly suitable for holding a touring shoe with two counter-bearing sections laterally protruding laterally from a front section of a sole of the touring shoe, particularly preferably with projections or pins, in order to pivotally hold a transverse axis Q running transversely to the longitudinal axis of the gliding board on the front unit , wherein a position of the projections relative to each other and relative to the sole of the touring shoe is fixed immovably. Such touring shoes are from the prior art, for example the publication DE 10 2009 059 968 A1 , known.

A front unit of a touring binding of the third embodiment differs from the front unit 2 of the first embodiment in the design of the bushing and the insert.

A bush 238 of the third embodiment has in particular a blocking section 242 with an inner surface 244 and a roof 246 and an exit contour 274. The exit contour 274 also has the function of a release contour and an entry contour, with the entry and exit states coinciding in contrast to the first embodiment. An indexing device of the front unit of the third embodiment is adapted to corresponding angular positions of the contours.

In the departure state, the touring shoe on the front unit of the third embodiment is achieved by an interaction of the front unit with a heel unit, not shown, in that the heel unit prevents the touring shoe from slipping out along a release path. In particular, the heel unit can press the counter bearing sections of the touring shoe against the inner surfaces 244 by means of a pretensioning device. If the touring shoe is triggered safely on a heel unit, in particular a Z-release, the counter-bearing sections of the touring shoe can leave the front unit essentially without resistance along the release path. Thus, in the third embodiment, the mechanism responsible for the safety release is transferred to the heel unit, while the front unit is set up not to impede a safety release caused by the heel unit.

An insert 236 of the third embodiment has a recess 230, the bottom 230a of which extends substantially perpendicular to the axis Q and has a depth, so that essentially no resistance to a counter movement of a touring shoe is brought into being by the recess 230 during a release movement.

Fourth embodiment

The base element 308 is preferably formed integrally with at least one of the second partial legs 314l, 314r, the first partial legs 312l, 312r and the inner axis bearings 314li, 314ri.

The base element 308 also preferably has a plurality of mounting openings 318, with the aid of which the front unit 302 can be attached to a sliding board by means of screws or similar fastening means.

Of the Bottom portion 306 connects pivot axes 310 and 324 as a first support member. Furthermore, a second support element 326 is preferably arranged pivotably on the bottom section 306 on the second pivot axis 324. The carrier element 326 preferably carries a third pivot axis 328 designed as a shaft. It is contemplated that a slide 330 can be pivotably attached to the second carrier element 326 via the shaft forming the third pivot axis 328, so that the third pivot axis 328 can be designed to be stationary with respect to the carrier 330 . The carriage 330 is preferably slidably guided on a carriage guide 332 of the base element 308. The slide guide 332 preferably comprises a guide rod 334 which is held by a front carrier 336 and a rear carrier 338. In a preferred embodiment, the slide 330 is biased by a spring 340 in the direction of the stop projection 337, the spring 340 preferably being arranged between the slide 330 and the rear carrier 338. The carriers 336 and 338 are preferably arranged stationary with respect to the base element 308, so that the slide guide 332 is arranged stationary with respect to the first pivot axis 310. The bottom section 306, the second carrier element and the slide 330 can, with the corresponding axes 310, 324 and 328, the slide guide 332 and the stop projection 337, form at least part of a locking arrangement of the front unit 302.

The first, second and third pivot axes 310, 324 and 328 are preferably aligned parallel to one another.

A first stop element 342 is preferably arranged on the lever 322 and, when pivoted in the direction W from the in FIG Figures 15 and 16 shown rest position of the lever 322 acts on the second carrier element 326 by a first angular amount a1 (for simplification this angular position of the lever 322 is also referred to, preferably with reference to the bottom section 306, a1). More preferred is on The lever 322 is arranged a second stop element 344 which, when pivoted in the direction W from the in Figures 15 and 16 shown rest position of the lever 322 by a second angular amount a2 on the bottom portion 306 (for simplification, this angular position of the lever 322, preferably referred to the bottom portion 306, called a2), the following applies to the angular amounts: a2> a1. It should be noted that the angles a1 and a2 are shown schematically in the figures and the difference between a1 and a2 corresponds to the angle through which the lever 322 in Figure 20 must be rotated so that the second stop element 344 strikes the bottom portion 306.

On the lever 322, preferably on the left or (and / or) right side, at least one, preferably two points of attack 346 for a flexible element 348 (possibly a respective left and right flexible element 348) are arranged, in which the flexible element Element 348, here in particular designed as a rope, is preferably arranged in a stationary manner on lever 322. In a preferred embodiment, the points of attack 346 are arranged on respective lever arms 350o, 350u. It should be noted that the course of the flexible element 348 in the figures, in particular Figure 15 , for the sake of clarity is only partially indicated schematically.

Alternatively, sufficient tension can be exerted on the contact surfaces of the lever arms 350o, 350u by tensioning the flexible element 348, so that the flexible element 348 is essentially fixed in relation to the lever arms 350o, 350u due to the friction. In a particularly preferred embodiment, an upper lever arm 350o has a contact surface 352 in the form of a groove 354 and a lower lever arm 350u can have a contact surface 356 in the form of an inner surface of an opening 358.

Via the respective points of attack 346 or the corresponding contact surfaces (generally sections of the attack), a first, here Upper section 348o or a second, here lower section 348u of the flexible element 348 a tensile load or a tensile force depending on a direction of rotation of the lever 322 are transmitted. The upper section 348o and the lower section 348u of the flexible element 348 are preferably guided via a deflection 360 to a bearing element 362, only the left bearing element being shown, the right bearing element being shown in FIG Figure 12 covered. The deflection 360 is preferably designed as a groove or as a plurality of grooves which each guide the upper section 348o and the lower section 348u of the flexible element 348 in a single groove. It is preferred that the deflection 360 is formed on the second partial leg 314l, 314r. The bearing element 362 preferably rotates about the cross-slide axis Q.

The left or right bearing element 362 is preferably designed as a bush 364. A first engagement point 366o (engagement section) for fixing a first section, preferably one end of the flexible element 348, and a second engagement point 366u (engagement section) for fixing a second section, preferably another end of the flexible element 348, are provided on the bushing 364 . In a preferred embodiment, an anti-slip device 368 in the form of a plate is provided on the bush 364, which holds and / or guides the flexible element 348 in a region between the anti-slip device 368 and a leg 304l, 304r. The anti-slip device 368 can also be used to turn the bush 364 in an emergency situation. The anti-slip device 368 can be formed on the bushing 364 via a pressing process, an adhesive process or via connecting elements, such as screws or rivets, or another suitable means. A rotation of the lever 322 is preferably coupled to a rotation of the bush 364 via the engagement points 366o, 366u and 346 or the corresponding contact surfaces.

The bushing 364 preferably has a through opening 370, which is formed along a bushing axis Q ′, which preferably coincides with a transverse axis Q of the gliding board in the assembled state. Furthermore, the bushing 364 preferably has a through opening 372, which is formed essentially transversely to the bushing axis Q ′ and preferably penetrates opposite wall sections of the bushing 364. The passage opening 370 is preferably formed essentially along the axis of rotation of the bearing element 362, here the bush 364, and is designed to receive a counter bearing section of the touring shoe, so that the pivot axis of the touring shoe in the front unit 302 can coincide with the axis of rotation of the bearing element 362. The bearing element, here the bushing 364, is set up to rotate about the pivot axis Q of the touring shoe in the front unit 302. The transverse axis Q can run transversely to the longitudinal axis of the sliding board and parallel to a sliding board plane / sliding board surface.

At one end 374, which in the ready-to-use state faces a counter bearing of a touring shoe, the bush 364 has a blocking section 376, which preferably has a roof 378 and / or an inner surface 380, the inner surface in a particularly preferred embodiment being a curved section 382 and at least one, in particular two, substantially flat sections 384. If two planar sections 384 are provided, they can be formed essentially parallel to one another. Likewise, a release contour 386 can be provided on the bush 364, which can be designed as a recess that runs essentially along the axis Q ′, in particular with respect to the axis Q ′ as a release slope. Furthermore, the bushing 364 can have at least one, preferably two entry contours 388. If two entry contours 388 are used, the same bushing 364 can be used for a left and a right side of the front unit 302.

One, particularly preferably both, of the entry contours 388 is preferably designed as a recess along the axis Q ′, in particular with respect to the axis Q ′ as an entry slope.

In a preferred embodiment, the bush 364 is mounted in an insert 390, which can in particular be mounted in a leg 304l, 304r. The insert 390 preferably has an opening 392 which is formed along an insert axis Q "of the insert 390, the insert axis Q" preferably essentially coinciding with the socket axis Q ′ and / or the axis Q in the assembled state of the insert 390. The insert 390 preferably has a projection 394 which extends essentially in the radial direction with respect to the insert axis Q ″, so that when the insert 390 is inserted, the projection 394 engages in a corresponding recess in a corresponding one of the legs 304l, 304r and thus the angular position of the insert 390 the insert axis Q "in this corresponding leg 304l, 304r. The opening 392 is preferably essentially a cylinder opening whose cylinder axis can coincide with the insert axis Q ″.

Optionally, the insert has at least one, preferably two section grooves 412, which are preferably not connected to one another and / or are preferably not designed to be completely circumferential and / or preferably penetrate the wall material of the insert 390. The insert 390 can also have a groove 398, via which the position of the insert 390 relative to the corresponding leg 304l, 304r in one direction along the insert axis Q, preferably by means of a C-ring (locking ring or groove ring in C-shape) "The position of the insert 390 relative to the corresponding leg 304l, 304r in a different direction along the insert axis Q" can be via the projection 394 or via an edge 396 of a collar which protrudes / protrudes, preferably in the radial direction with respect to the insert axis Q " 402. The collar 402 can move the Prevent thrust bearing section out of the bearing element in a direction essentially downwards and / or a direction essentially forward. The position of the insert 390 relative to the corresponding leg 304l, 304r can be achieved by engaging at least one pin 408, preferably two pins 408, in one of the section grooves 412, preferably in an end section of the respective section groove 412, and in at least one opening (not explicitly shown ) in the corresponding leg 304l, 304r. The position of the bushing 364 along the axis Q ′ or Q ″ or Q with respect to the insert 390 can be secured by a pin 410 engaging in the through opening 372 and in the two of the section grooves 412.

In order to allow Z-triggering to take place in a defined manner, a release path 400 is defined on the bearing arrangement 304, preferably on each of the U-shaped legs 304l, 304r. The release path 400 can be defined by a spatial structure in the bearing arrangement 304, for example an interruption 414 of the collar 402, which can enable and / or guide a movement of the counter bearing sections of the touring shoe. The release path 400 preferably runs essentially parallel to a sliding board plane.

Furthermore, an entry path 404 can be defined on the bearing arrangement 304, which is preferably defined via a recess 406, along which a counter bearing section of the touring shoe can get into the front unit 302 of the touring binding, for example it can slide, in order to be held on the front unit 302. The recess 406 is preferably formed in the insert 390, in particular in the projection 394. The boarding path 404 preferably runs perpendicular to the plane of the sliding board in a boarding state of the front unit 302.

The function of the fourth embodiment is described in detail below. In an entry state, one of the entry contours is 388 aligned with the recess 406, so that a counter bearing section of a touring shoe is guided through the recess 406 to the entry contour 388, as a result of which it reaches the bearing element 362, preferably the through opening 370, along the entry path 404.

The recess 406 is preferably oriented vertically in the boarding state, so that the boarding path 404 runs essentially perpendicular to the plane of the sliding board in the departure state. Likewise, in an entry-level state, which preferably coincides with the departure state, the trigger contour 386 is aligned with the release path 400, so that Z-triggering can take place particularly easily. In the departure state, the front unit is set up to hold a touring shoe and is thus in a holding configuration.

In the departure state and boarding state, one leg 304l or 304r bears against a first partial leg 312l or 312r, whereby rotation of the bearing arrangement 304 in a direction R is prevented. At the same time, the carriage 330 abuts a stop projection 337 of the base element 308, the second carrier element 326 being deflected in the direction of the front carrier 336 or the stop projection 337 from an orientation perpendicular to a displacement path of the carriage 330. Furthermore, the axis 328 can form the contact element of the carriage 330 on the stop projection 337. Due to this deflection, a pivoting of the bearing arrangement 304 about the pivot axis 310 in the R opposite direction would lead to a movement of the carriage 330 in the forward direction, but this is prevented by the carriage 330 striking the stop projection 337, so that in the departure state and boarding state also one Swiveling of the bearing arrangement 304 in the opposite direction R is prevented. With this position of the carrier and the carriage, the front unit is in a locked state, since a transition from the Holding configuration to a still to be described exit configuration is prevented.

The lever 322 is now based on the departure state and boarding state of the Figure 20 pivoted opposite to the direction W, the opening of the release contour 386 is aligned in the direction of the collar 402 by means of the flexible element 348, so that a counter bearing section of a touring shoe cannot leave the bearing element, this state can be regarded as part of the holding configuration. In particular, the release path in this position of the bush 364 is blocked by the blocking section 376 in such a way that the counter bearing section cannot leave the bearing element and the front unit 302 is in a blocked state. Furthermore, in the blocked state, the roof 378 not only prevents the counter bearing section from moving out of the bearing element along the entry path, but in particular prevents the counter bearing section from entering the bearing element since it blocks the entry path. In the blocked state, the touring shoe can be pivoted on the front unit 302 during the ascent about a transverse axis Q running transverse to the longitudinal axis of the gliding board. In the blocked state, the arrangement of the axes 310, 324 and 328 is essentially the same as their arrangement in the departure state and boarding state.

If the lever 322 is pivoted out of the blocked state of the front unit 302 in the direction W, the front unit 302 changes again to the departure state and the boarding state.

If the lever 322 is pivoted from the rest position in the direction W up to the angle a1, the first stop element 342 engages the second carrier element 326 and when the lever 322 is rotated further, the second carrier element 326 is pivoted against the force of the spring 340. This pivoting is made possible by the flexibility of the guide rod 334 and / or allows sufficient play of the slide 330 on the guide rod 334. If, starting from the rest position of the lever 322, it is pivoted up to the angle a2, then the second carrier element 326 is rotated / pivoted beyond an orientation that is perpendicular with respect to a displacement path of the slide 330, so that the second carrier element 326 in the direction of the rear Carrier 338 deviates from this vertical orientation, a dead center position of the arrangement of the second carrier element 326, the bottom section 306 and the guided carriage 330. From the point in time at which the vertical orientation of the second support element 326 deviates in the direction of the rear support, the base section 306 can pivot in the opposite direction R, which allows a transition from the holding configuration to an exit configuration which is yet to be described Dear locking state of the front unit.

Since the second stop element 344 engages the bottom section 306 when the angle a2 is reached by the lever 322, the bottom section 306 is pivoted counter to the direction R when the force is exerted in the K direction, so that the bearing arrangement 304 and with it the bearing element 362 are in one Longitudinal sliding board direction, particularly forward, moves whereby a touring shoe is pulled out of a heel unit, if any, and the front unit is in an exit configuration because the touring shoe is not prevented from being pulled out of the front unit 302 by a heel unit. When the angle a2 is reached by the lever 322, preferably both the first stop element 342 engage the second support element 326 and the second stop element 344 the bottom section 306. When the lever 322 changes from the angle a1 to the angle a2, the bushing 364 can rotate somewhat further in the direction S, but the angle through which the bushing 364 thereby swings is preferably relatively small and has accordingly not been shown in the figures . In a preferred embodiment, another Rotating the book 364 at a transition of the lever 322 from the angle a1 to the angle a2 by striking the pin 410 at one end of one of the section grooves 412, preferably by striking the pin 410 with respect to the circumferential direction of the opening 392 one, with respect to a circumferential direction of the opening 392, end of a first section groove 412 and at one, with respect to a circumferential direction of the opening 392, end of a second section groove 412, prevented. In this case in particular, it is contemplated that the flexible element 348 is set up to expand so far that even when the pin 410 stops at one end of the groove 412 as described above, and thus a blockage of a further rotation of the bush 364 , The lever 322 can pivot further about the axis 324 until the angle a2 is reached and the second stop element 344 can strike the bottom section 306.

The lever 322 can be rotated further until the axis 324 strikes the guide rod 334. When this stop is reached, the bush 364 is not or only slightly rotated further towards S when the stop 322 is moved by the movement of the lever 322 relative to its position in the departure state and entry state, so that no element blocks the release contour and the user slips through the touring shoe can release a slight lateral pivoting from the front unit 302, the front unit is in an exit state, which can be regarded as part of the exit configuration. If the lever 322 is no longer acted upon by a force, the spring 340 drives the carriage 330 forward, whereby due to the abutment of the first stop element 342 on the second support element 326 and the second stop element 344 on the bottom section 306 (over respective angular ranges, compare above) the front unit 302 transitions to the entry and exit states, with the movement of the lever 322 being coupled to the movement of the bush 364.

In the exit state, the departure state and the entry state, the front unit 302 is in a neutral state, since the release path is not blocked and a movement of a counter bearing section is permitted.

In principle, it is possible to provide points of attack on a socket of one of the first three embodiments and to use these instead of the socket 364, the insert from the corresponding first, second or third embodiment preferably being used instead of the insert 390.

Fifth embodiment

With reference to the Figures 23 to 26 A fifth embodiment of the invention is described below, which is also a modification of the first embodiment, so that only the differences from the first embodiment are described in more detail below and reference is expressly made to the description of the first embodiment.

A rotatable bush 438 of the fifth embodiment is rotatably mounted about an axis of rotation R and has on its front side facing the shoe a blocking section 442 which is formed by a circumferential section projecting in the axial direction R on the shoe side. The protruding circumferential section can extend in the circumferential direction of the bushing over more than 90 °, preferably over more than 180 °.

A release section is formed on a circumferential section of the bush 438 diametrically opposite the blocking section 442 and forms a release contour 454. The trigger contour 454 has an inclined surface (release inclined surface) which faces the axis of rotation R and to the axis of rotation at an angle between approximately 30 ° and runs approximately 60 °. This release bevel surface is therefore designed to reject a pin recessed in the socket 438 when the binding is released and to lead it out of the socket 438.

The bearing arrangement of the front unit of the fifth embodiment also has an entry inclined surface 434 which leads to the bush 438 and which forms an entry contour. The entry inclined surface 434 extends at an angle between approximately 30 ° and approximately 60 ° to the axis of rotation R and faces away from the axis of rotation. When entering the binding, a pin provided on the shoe can be guided into the interior of the socket 438 along the entry inclined surface 434.

In order to get into the binding, the front unit of the fifth embodiment can be inserted into the Figure 24 shown position can be set by the bush 438 is brought into such a rotational position that the release contour 454 is aligned in the horizontal direction, in particular towards the rear. To get in, the ski boot is brought up from above, so that the pins of the ski boot slide off the entry inclined surface 434 and enter the socket 438. For this purpose, the pins are advantageously mounted on the shoe in an axially movable manner and are biased outwards by means of a spring. The front unit is then directly in a downhill position in which the pin of the ski boot is normally held in the socket 438, but can exceed the predetermined release force by leaving the socket 438 via the release contour 454 in the horizontal direction. Sliding out of the pin from the socket 438 in the vertical direction, or forward in the exemplary embodiment, on the other hand, is reliably prevented. When released, the pin in turn slides on the inclined surface of the release contour 454. A trigger value is thus influenced by the pretension of the pins on the one hand and by the inclination of the inclined surface of the trigger contour 454 on the other hand.

To adjust the front unit to the walking position, the bush 438 can be rotated through 90 ° until the blocking section 442 points upwards and the trigger contour 454 points downwards. A collar 403 of the bearing element adjacent in this position to the release contour 454 prevents the pin from sliding out in the vertical downward direction in this walking position of the front unit. Sliding out upwards or in the horizontal direction, on the other hand, is prevented by the blocking section 442, which extends by more than 180 ° in the circumferential direction. In this position, the front unit is completely blocked and does not allow the pin to exit the socket 438.

A further rotation of the bush 448 by 180 ° from the walking position or by 90 ° from the entry and exit position ( Fig. 24 ) puts the front unit in an exit position, which in Figure 25 is shown. In the exit position, the release contour 454 points vertically upwards. The pin can now leave the socket 438 via the inclined surface of the release contour 454 in order to free the shoe from the binding for exiting. In the fifth embodiment, the release contour 454 thus has a double function to enable a safety release on the one hand and to exit the binding on the other.

Drehungen um Winkel von ca. 90°, ca 180° etc. sind für Nutzer besonders intuitiv und leicht erlernbar.Instead of rotating the bush 448 by 90 °, in a variant of the fifth embodiment an adjustment of the front unit between entry and departure position, walking position and exit position can also be done by rotating the bush 448 through an angle $$\alpha =\beta +n\ast 90°$$

take place, where 80 ° ≤ β ≤ 100 °, preferably β = 90 °, and n ≥ 0 is a natural number. Rotations through angles of approx. 90 °, approx. 180 ° etc. are particularly intuitive and easy to learn for users.
