Abstract

The touring binding has two bearing portions arranged on different sides of a longitudinal axis. A longitudinal positioning portion separated from the bearing portions is provided, at which the shoe is so supported in a stepping position that the counter bearing portions are positioned in a position ready to engage to the bearing elements with respect to their position along the longitudinal axis. The longitudinal positioning portion in the open position is set in an upright position for supporting the shoe in the stepping position. The bearing portions are adapted to retain opposite lateral counter bearing portions of a shoe in engagement in a walking position of the touring binding to hold the shoe about a transverse axis pivotable at the touring binding. The longitudinal positioning portion is set in another position folded forward in the walking position, in which it allows a pivoting of the shoe about the transverse axis for walking.

Description

The present invention relates to a touring binding comprising two arranged on different sides of a longitudinal axis bearing portions which are adapted to take in a walking position of the touring binding opposite lateral abutment portions of a shoe to the shoe about a transversely to the longitudinal axis extending transverse axis pivoting on the Keep touring binding.

Touring bindings of this type are particularly attached to touring skis and used together with an heel box, so that the touring can be adjusted in a walking position for ascent, in which the heel machine releases the heel of the shoe and the shoe can swing freely around the bearing sections, and at a Downhill the touring binding can be set in a downhill position, in which the heel counter holds the heel of the shoe securely on the ski. However, the touring bindings discussed within the scope of this disclosure may equally be used with splitboards (longitudinally divisible snowboards, the halves of which may be used for ascent during touring) or even snowshoes.

An example of a known from the prior art touring binding of the type mentioned is in the EP 0 199 098 A2 discloses and includes two lateral, inwardly facing pins as bearing portions which engage in corresponding side holes of a front portion of a touring ski boot. The pins are attached to distal ends of respective clamping brackets, the clamping brackets being pivotally supported on the touring binding for opening and closing the touring binding and being movable between the open position and the closed position by means of a binding actuation arrangement. When boarding in the well-known Touring binding, the ski boot must be positioned so that its lateral bearing holes are just opposite the bearing pins of the touring binding, so that when closing the binding, the bearing pins can snap into the bearing openings. The correct positioning of the ski boot can often be difficult in practical use on the mountain, especially for inexperienced users.

To facilitate finding the correct entry position for the ski boot, the EP 1 559 457 A1 a trained on the ski boot in the field of bearing openings access aid, which leads to the insertion of the ski boot in the forward direction, the pins to the correct position in juxtaposition to the bearing openings. With this boarding aid the entry into the touring binding can be significantly facilitated, however, the reliability of the correct positioning of the ski boot is limited by the boarding aid in that too much cantilevered design of the boarding aid on the ski shoe affects the usability of the ski boot when moving without skis. If, in particular, rocky subsections need to be overcome without skis, pronounced access aids to the lateral bearing openings can harbor the risk that the user will get caught on a rock ledge with the ski boot.

Known touring bindings can be placed after boarding and closing the binding either in a walking position in which a heel machine releases the heel of the shoe, so that the shoe is pivotable about the transverse axis, or can be set in a down position, in which the automatic heel Keep the heel of the shoe fixed, so that the shoe is kept fixed overall near the surface of the ski. In order to be able to ensure a safety release of the binding in the event of a fall, ie releasing the shoe from the binding when a predetermined release force is exceeded, are, for example, according to the EP 0 199 098 A2 the clamping pins holding the clamping pins by means of springs in the engaged position with the bearing holes biased. When a force in the lateral direction (transverse to the ski axis, or a torque about a vertical axis of rotation to the ski) acts on the shoe, the clamping angles are pivoted against the force of the springs and the bearing pins are pressed laterally out of the bearing openings, so that the ski can be detached from the shoe.

This safety release is particularly undesirable in sportier use of touring skis, such as the touring ski competition sport. The partially high forces on the binding in the lateral direction during the ascent can then sometimes exceed the triggering force, so that the tour binding triggers and the user loses the ski. To prevent this, have known touring bindings, such as in the EP 0 199 098 A2 , an additional locking mechanism that locks in the walking position the clamping bracket and unlocked in the down position to allow a safety release. However, such a locking device not only draws the disadvantage of additional design effort and increased weight, but can often not ensure reliable locking with sufficient security. In addition, special operating effort for locking and unlocking is necessary.

Against this background, it is an object of the present invention to provide a touring binding, which has improved functionality and operability to avoid the above-mentioned disadvantages of the prior art, and which in particular facilitates the correct positioning of the shoe at the entrance and / or unintentional release of the bond can avoid.

According to a first aspect of the invention, said invention object is achieved by a touring binding, comprising two bearing sections arranged on different sides of a longitudinal axis, which are adapted to engage opposite side abutment portions of a shoe in a walking position of the touring binding, around the shoe transverse to the longitudinal axis Pivoting transverse axis to the touring binding, characterized by a separate from the bearing sections Längspositionierabschnitt on which the shoe is supported in an entry position so that the abutment portions are positioned with respect to their position along the longitudinal axis in engageable position to the bearing elements.

According to the first aspect of the invention, there is thus provided a longitudinal positioning portion on the touring binding on which the shoe can be supported in the correct entry position. When entering the binding, the user must thus support the shoe only on the longitudinal positioning and thus can easily find the correct position for closing the binding. Even inexperienced users can thus easily and intuitively operate the binding and getting into the binding succeeds even under difficult conditions.

The positioning of the shoe by the longitudinal positioning takes place in view of the position of the shoe along the longitudinal axis of the touring binding. The longitudinal axis of the touring binding is defined by the direction of travel of the ready-mounted touring binding, which is defined by attachment means, such as mounting holes of the touring binding. In particular, the user can guide the ski boot by forward movement along the longitudinal axis to the longitudinal positioning section and support it there, until the counter bearing sections are positioned in a ready-to-engage position. The positioning in the vertical direction (vertical to the board plane of the ski or snowboard etc.) can be carried out advantageously by another support portion of the touring binding.

Particularly preferably, the longitudinal positioning section comprises a stop against which a front section of the shoe strikes in the entry position. The longitudinal positioning can then constructively simple structure in the form of particular a stop surface, a stop line or a stop point. As a front section of the shoe For example, all sections of the shoe pointing in the forward direction or obliquely in the forward direction are possible, in particular surface sections whose surface normals enclose an angle between 0 and 90 ° with the forward direction. Particularly preferably, the longitudinal positioning portion will be a front stop which engages with a front portion of the shoe located in front of the abutment portions of the shoe in the sole region.

In a preferred embodiment of the invention it is provided that the touring binding is adjustable between an open position in which the bearing portions and the abutment portions are disengaged, and the walking position in which the bearing portions and the abutment portions are engaged with each other, wherein the Längsositionierabschnitt in the Opening position is placed in a first position for supporting the shoe in the entry position and placed in the walking position in a second position or adjustable, in which it allows pivoting of the shoe about the transverse axis to walk. In such an embodiment, the shape and size of the Längsositionierabschnitts is not limited by the guaranteed freedom of movement of the ski boot. Thus, for example, a relatively large, easy to find when boarding stop can be provided, which is then folded away in the walking position, for example, to allow pivoting of the shoe. The mentioned embodiment thus increases the design freedom for the longitudinal positioning section.

The adjustment of the longitudinal positioning portion from the first position to the second position mentioned in the embodiment described above can be done by a manual operation by the user, so that a simple structure for the longitudinal positioning portion can be selected. Particularly comfortable, however, can be provided that is adjusted in an adjustment of the touring binding of the open position in the walking position of the longitudinal positioning from the first position to the second position. Thus, the Längsositionierabschnitt in the open position For example, provide the desired stop in the form of a stop member, wherein the already taking place for the closing of the binding and the transition to walking position movement or adjustment of the touring binding is used simultaneously for the movement or adjustment of the stop element in the second position in which the stop element the swinging motion of the shoe is not hindered.

An adjustment of the Längsositionierabschnitts from the first to the second position may also be effected by a pivotal movement of the shoe about the axis of the bearing portions, so that the Längsositionierabschnitt is displaced in the walking position in the first step of the user from the first position to the second position.

According to a functional principle known per se, the touring binding can be adjusted by means of a binding actuation arrangement by a user from the open position to the walking position, wherein the bearing sections are moved towards each other and then come into engagement with the abutment portions of the shoe. According to a further embodiment of the invention, in a touring binding with such a binding actuation arrangement, a coupling is provided which provides a transmission of an adjustment movement of the binding actuation arrangement on the longitudinal positioning section. Thus, an operation of the binding operation assembly can be coupled with a displacement movement of the longitudinal positioning portion, so that the movement of the longitudinal positioning between the first and second position can be carried out without increased operating effort by the user.

A longitudinal positioning section which can be adjusted between a first and a second position can furthermore preferably be biased in the direction of the second position and be lockable in the first position. In order to adjust the longitudinal positioning section to the second position, it may be sufficient if the locking of the first position is released, such that the actual movement of the longitudinal positioning section towards the second position and the retention of the longitudinal positioning section in the second position can be achieved by the force of an elastic means. In this way, technical effort for guiding the movement of the Längspositionierabschnitts over the adjustment can be saved away.

In a further preferred embodiment of the invention, it is provided that the coupling comprises a control lever which is coupled to the binding actuating arrangement, wherein the control lever has a support section, on which the longitudinal positioning section is supported in the first position, to a movement of the Längsositionierabschnitts to the second position to block, and wherein the control lever is arranged in a closed state of the touring binding so that the support portion allows movement to the second position. By such a control lever, a structurally simple coupling between the binding operation arrangement and Längspositionierabschnitt can be realized. The mentioned closed position of the touring binding can be an already mentioned walking position or a downhill position of the touring binding, in which a heel portion of the shoe is fixed to the ski. If the support portion of the control lever in the closed position allows movement of the Längsositionierabschnitts to the second position, this does not necessarily mean that this movement actually takes place. For example, in a downhill position (also a closed position), instead of the support section of the control lever, another locking element of the touring binding could assume the supporting of the longitudinal positioning section in its first position.

According to a second aspect of the invention, the above-mentioned object of the invention is achieved by a touring binding comprising two bearing sections arranged on different sides of a longitudinal axis which are adapted to engage opposite lateral abutment sections of a shoe in a closed position of the touring binding around the shoe one transverse to the longitudinal axis extending transverse axis pivotally attached to the binding assembly, and a separate from the bearing sections side support assembly on which a front portion of the shoe in the closed position of the touring binding for blocking a movement of the shoe is transverse to the longitudinal direction supportable.

An important feature of the second aspect of the invention is the provision of a side support assembly for blocking a lateral movement of the shoe in the closed position of the touring binding, whereby a force of the shoe acting laterally during the use of the touring binding is not achieved, or not at most only partially introduced into the bearing sections, but instead can be completely or at least partially absorbed by the side support assembly instead. The fact that the side support assembly is provided separately from the bearing sections, especially in touring bindings, in which the bearing portions are movable in the lateral direction between open and closed positions, a skifestes side support member can be used, which is firmly connected to a ski to be fastened base body of the touring binding so that the forces acting on the touring binding from the shoe in the lateral direction can be stably absorbed by the touring binding. A lateral release of the touring binding can then be done only by triggering the heel counter, so that the desired tripping characteristics, in particular the Mz tripping torque can be reliably controlled by appropriate settings of the heel unit.

A structurally simple embodiment, which at the same time allows a very stable absorption of the forces exerted laterally by the shoe on the binding, uses a side support arrangement attached to a ski body of the touring binding or for attachment to the ski (or on board, snowshoe, etc .) is set up. When the side support assembly includes a left side support portion for supporting a left outer front side portion of a shoe and a right side support portion for supporting a right outer front side portion of a shoe, the side support assembly can reliably cooperate with all the shoes for the mount portions of the touring binding and a support in the left and right direction.

A reliable and material-saving support is made possible if the side support assembly has at least one at least partially adapted to an outer contour of a shoe stop surface. The forces acting in the lateral direction can then be introduced over a relatively large area in the side support assembly, so that the wear of the touring binding and the shoe used can be reduced.

In a further embodiment of the invention, it is proposed that the side support arrangement is arranged adjacent to the bearing sections of the touring binding. In this way, a compact design of touring binding can be achieved and the introduction of lateral forces in the bearing sections can be reduced as much as possible.

In order to realize a particularly compact design, it can be thought that at least one of the bearing sections is arranged on a pivotable clamping angle, wherein the at least one clamping angle has a recess and wherein the side support arrangement is at least partially disposed in the recess. The at least one clamping angle can then move relative to the side support assembly for opening and closing the touring binding, wherein at the same time both components can be arranged very close to each other and substantially even without increasing the installation space.

Particularly preferably, a touring binding of the invention realizes the Features of the first aspect of the invention and the features of the second aspect of the invention, in particular in each case according to their aforementioned developments. The combination of the two aspects in a touring binding results in addition to the advantages listed above each of the further effect that gives the user by the side support assembly and the Längspositionieranordnung the impression of comprehensive, all-round positioning and leadership of the shoe on the touring binding for the purpose of boarding becomes. Thus, when entering the user, the user can position the shoe in the longitudinal direction through the longitudinal positioning arrangement and, at the same time, orientate himself using the side support arrangement in order to find the correct position in the lateral direction.

A particularly advantageous saving of installation space and design effort can be achieved if the longitudinal positioning arrangement comprises a stop on which abuts a front portion of the shoe in the entry position, the side support assembly comprises at least one side support portion for supporting an outer front side portion of the shoe, wherein the Longitudinal positioning and the side support assembly are formed by the same stop assembly, and wherein the front stop of the longitudinal positioning and the side support portion adjacent to a common stop member formed or formed as the same stop on a combination stop member. In such variants of the invention, both aspects, namely longitudinal positioning and side support, can be realized by a common stop element or combination stop element, so that construction effort and weight of the touring binding can be reduced.

In the present disclosure, directional and location indications such as "top," "bottom," "left," "right," "front," "rear," "vertical," "horizontal," or the like refer to an operationally mounted condition of the FIG Touring bindings in which they are attached, for example, to a touring ski and the observer understanding these terms stands on a horizontal surface and looking forward in the direction of the ski touring. An axis running in the X-direction then runs parallel to the viewing direction and parallel to the longitudinal axis of the touring ski, a Y-direction is orthogonal to the X-direction and parallel to the horizontal background and a Z-direction is orthogonal to the X-direction and the Y-direction in a vertical direction to the horizontal ground.

With reference to FIGS. 1a to 3g a first embodiment of the invention will be described below.

The touring binding 10 of the first embodiment comprises a base plate 12 for attaching the touring binding 10 to a ski (indicated by reference numeral 14 in FIG Figures 1a, 1b and 1c ), Clamping bracket 16 for holding and pivotally supporting a touring ski boot, a binding operation mechanism 18 for operating the touring binding 10, in particular the clamping angle 16, and a stop element 20 as a positioning aid for the ski boot when getting into the touring binding 10th

For attachment to the ski 14, the base plate 12 may include a plurality of mounting holes 22 into which mounting screws to be screwed into the ski 14 may be inserted. Integrally formed on or attached to the base plate 12 are left and right bearing portions 24 which each hold the clamping brackets 16 about a pivot axis 26 extending in the X direction.

Each clamping bracket 16 has a first arm 28 extending substantially upwardly from the pivot axis 26 and a second arm 30 extending substantially from the pivot axis 26 toward the center of the ski. At an upper distal end of the first arm 28, there is respectively disposed a journal 32 whose tip is substantially inwardly, i. towards the ski center, shows. The bearing pin 32 is arranged in a conventional manner for intervening in a lateral bearing opening of a ski boot to keep the ski boot in a walking position of the touring binding 10 about an axis extending in the Y direction transverse axis Q pivotally mounted on the touring binding 10.

The ski center facing distal ends of the second arms 30 of the clamping bracket 16 are jointly grasped by a fork-like end portion 34 of an actuating lever 36 of the binding actuating mechanism 18 which is pivotally mounted about a pivot axis 38 extending in the Y direction on a bearing portion of the base plate 12. Specifically engages the fork-like end portion 34 in the embodiment each have an end cap 40 of each clamping bracket 16, which is slidably slidable on each of the second arm 30 of each clamping bracket 16 projecting pins 42 so that each of the end caps 40 along the pins 42 can move in the Y direction , By means of compression springs 44 wound around the pins 42, the end caps 40 are biased towards the center of the ski and thus toward one another and are pressed into contact with one another. In an known manner, a pivoting movement of the actuating lever 36 about the pivot axis 38 to a vertical movement of the two end caps 40 and thus to a pivotal movement of the clamping bracket 16 about the pivot axes 26th

At a distal end of the fork-like end portion 34 facing away from the second arm 46 of the actuating lever 36, a control lever 50 is pivotally supported on a pivot axis 48 extending in the Y direction. The operating lever 50 has an operating portion 52 which is manually or by means of a Skisstocks (for example, via a ski pole receiving trough 54) operable to move the binding between open position and closed position. Further, the operating lever 50 comprises a locking portion 56 facing away from the operating portion 52, which is adapted to come in contact with a cam surface 58 on the top of the base plate 12 or the ski 14 during pivotal movement of the operating lever 50 to an upward or downward movement the second arm 46 of the operating lever 36 to force according to the surface contour of the cam surface 58 and thus to control the pivotal movement of the actuating lever 36 and thus also the pivotal movement of the clamping bracket 16.

The operating lever 50 is connected to the actuating lever 36 not only via the pivot axis 48 in connection, but also via a slotted guide from a running in the Y direction free pin 57, which is guided in a link 59 in the operating lever 36 so that it is substantially in the X direction along the operating lever 36 can move. Between the pin 57 and the pivot axis 48, a tension spring not shown in the drawings is tensioned, so that the pin 57 is biased in the direction of the pivot axis 48. The pin 57 abuts a cam surface 61 of the operating lever 50 and is pressed by the tensioned between the pivot axis 48 and pin 57 tension spring into abutment against the cam surface 61. The cam surface 61 is formed (for example, with a vertex) so that the operating lever 50 with respect to a Pivoting movement relative to the operating lever 36 has two stable states, namely the in FIGS. 1a to 1g shown state in the open position in which the operating lever 50 is folded down, and the in FIGS. 3a to 3g shown state of the second closed position in which the operating lever 50 is folded upwards.

Furthermore, the operating lever 50 comprises a support portion 60 for the stop element 20, on which the stop element 20 can be supported in a first closing position to be described later.

The stop member 20 has a rear abutment surface 62 adapted to be in abutting contact with a front sole portion of a mating touring ski boot. The stop element 20 is pivotally mounted on a bearing portion of the base plate 12 about a pivot axis 64 extending in the Y direction. By means of a folding mechanism to be described below, it can be achieved that the contact surface 62 is arranged in the open position in such a position that a touring ski shoe adjoining it with its front sole portion is positioned ready for entry, i. in particular such that with regard to a displacement of the touring ski boot in the X direction, the lateral bearing openings of the touring ski boot are arranged at the position of the bearing pins 32.

The pivoting movement of the stop element 20 is controlled by a folding mechanism, which comprises a control lever 66, which is held on a bearing portion of the base plate 12 about a pivot axis 68 extending in the Y direction. A first arm 70 of the control lever 66 has at its distal end a support portion 72 which is adapted to come into abutting engagement with a mating support portion 74 of the stop member 20 for pivotal movement of the stop member 20 forward (counterclockwise in FIG Figures 1b . 1e and 1f ) to limit.

A second arm 76 of the control lever 66 is coupled with the operating lever 50 for transmitting movement and transmitting force. In the exemplary embodiment, a distal end of the second arm 76 has a link 78, in which the pivot axis 48 of the operating lever 50 engages, so that the pivot axis 48 is guided in the link 78.

As in the FIGS. 1a to 1g of the first embodiment, in addition to the rear abutment surface 62, the abutment element 20 may each have a lateral abutment surface 82 and / or an upper abutment surface 84. The lateral abutment surfaces 82 are adapted to have lateral forward portions of a sole portion of a mating portion Touring ski boot in abutment, while the upper abutment surface 84 may be adapted to overlap a front of a suitable touring ski boot in a conventional manner tongue-like forward front sole portion from above.

In the first embodiment, the rear abutment surface 62, the lateral abutment surfaces 82 and the upper abutment surface 84 are formed as integral portions of the same stop element 20 and merge into one another. By the stop element 20 thus the entire front sole portion of the touring ski boot can be positively locked in both the X direction and in the Y direction and in the Z direction and allows intuitive positioning of the ski boot when boarding, as well as a secure grip in the ready to move position. Cost-effective, the stop element 20 can be made of a single casting, in particular plastic injection molded part.

Hereinafter, the operation of the touring binding 10 of the first embodiment will be described with reference to FIGS FIGS. 1a to 3g explained in more detail.

FIGS. 1a to 1g show the touring binding 10 in the open position in which the clamping angles are pivoted apart so that a Ski boot between the journals 32 can be used, or can be withdrawn from the procedure. In the open position, the end caps 40 are above a horizontal connecting line between the pivot axes 26 of the clamping angle 16, so that the compression springs 44 transmit a force in the opening direction on the clamping angle 16 (torque about the pivot axes 26 in the sense of increasing the distance between the bearing pin 32). , The second arm 46 of the operating lever 36 is approximated to the maximum ski 14 and the operating lever 50 is stretched to the top of the ski 14 or on the cam surface 58 at.

The pivoted in the opening direction downward second arm 46 of the actuating lever 36 holds on the pivot axis 48 and the second arm 76 of the control lever 66 in a lower position, so that the opposite first arm 70 of the control lever 66 and thus the support portion 72 of the control lever 66 upwards is pivoted and rests against the mating support portion 74 of the stop member 20. The stop element 20 can thus not fold away in the open position to the front. Preferably, the stop element 20, for example via a spiral spring wound around the pivot axis 64 of the stop element 20, extends forward (ie in FIG Figures 1b . 1e and 1f counterclockwise) biased against the support portion 72 of the control lever 66.

In the open position, a suitable touring ski boot can be inserted from behind into the stop member 20 until a front sole portion of the shoe abuts against the rearward facing surface 62, front lateral sole portions of the shoe engage the lateral abutment surfaces 82 and the upper abutment surface 84 engages the forward facing Sole section of the shoe overlaps. The touring ski boot is then supported in an entry position, with the rear abutment surface 62 acting as a longitudinal positioning section. In the entry position, the bearing openings of the ski boot lie with respect to their position along the X-direction (longitudinal axis of the touring binding) in the position ready for engagement to the bearing pin 32 is positioned. This means here that the bearing journals 32 just opposite the bearing openings of the ski boot, so that in a subsequent closing of the touring binding 10, the bearing pins 32 easily slide into the bearing openings of the ski boot and can engage there. Thus, the rear abutment surface 62 forms a front stop against which a front portion of the shoe abuts in the boarding position to position the shoe in an engageable manner.

A vertical position of the ski boot is defined in the entry position not only by the upper abutment surface 84 of the stop member 20, but also by a lower middle sole portion of the ski boot resting on an upper surface of the fork-like end portion 34 of the operating lever 36 and end caps 40, respectively. For adjusting the touring binding 10 from the open position to an in FIGS. 2a to 2g The first closed position shown by the user by applying a pressure in the Z direction down to the fork-like end portion 34 and the end caps 40, the actuating lever 36 in Figures 1b . 1e and 1f Swivel clockwise until the operating lever 36, the in FIGS. 2a to 2g reached shown position.

How very clear in FIG. 2a it can be seen, the end caps 40 are in the first closed position below a horizontal connecting line between the pivot axes 26 of the clamping bracket 16, so that the force of the compression springs 44, the end caps 40 further pushes towards the ski. Thus, the clamping angle 16 and the binding actuating mechanism 18 go through during their movement from the open position to the first closed position a dead center, so that the pressure force from the user on the fork-like end portion 34 and the end caps 40 must be applied only to the dead center and the touring binding 10 then automatically in the first closed position snaps.

With the lowering of the fork-like end portion 34, the second lifts Arm 46 of the actuating lever 36 and thus also the control lever 50 mounted thereon. The pivot axis 48 of the operating lever 50 slides in the link 78 to an upper end of the gate and then raises the second arm 76 of the control lever 66 also. As a result, the control lever pivots 66, so that the first arm 70 of the control lever 66 in the in FIGS. 2a to 2g shown position is lowered. With the lowering of the first arm 70 of the control lever 66 down the support portion 72 of the control lever 66 lifts from the mating support portion 74 of the stop member 20 and immersed in a recess 86 of the stop member 20, so that the pivotal movement of the stop member 20 in the forward direction (counterclockwise in the figures) is no longer limited by the support portion 72 of the control lever 66.

The first closed position may be a downhill position, in which the touring binding 10 is set up for a downhill run and, for example, an automatic heel unit (not shown) holds a heel portion of the boot fixed to the ski. In a downhill position, a front stop for positioning the shoe in the X-direction per se is not necessarily required, so that in one embodiment, the stop element 20 could already fold away in the first closed position to the front. In the embodiment shown in the figures, however, in the first closed position, the support portion 60 of the operating lever 50 comes into contact with the stop element 20, here with a second mating support portion 88 on a front side of the stop element 20. Thus, in the first closed position, a forward pivoting movement of Stop element 20 is no longer limited by the support portion 72 of the control lever 66, since this is immersed in the recess 86 on the stop element 20, but through the support portion 60 of the operating lever 50th

If the stop member 20 continues to abut the front sole portion of the shoe in the first closed position, this may provide the additional advantage that the lateral abutment surfaces 82 serve as a side support assembly can be used, on which a front portion of the shoe for blocking movement of the shoe in the Y direction (transverse to the longitudinal direction) can be supported. If the first closed position is a downhill position of the touring binding 10, an unwanted triggering of the touring binding 10 in the region of the toe can be prevented during a downhill run. This does not have to mean that a safety release of the touring binding, in particular an Mz release (release of the bond when a torque is exerted about a Z-axis), is no longer guaranteed. Rather, in such a touring binding 10, the triggering of Mz via a triggering mechanism of the heel unit (not shown) can take place in a manner known per se, so that the triggering characteristics and triggering thresholds can be conveniently set only on one component, namely on the heel counter. In particular, sporty drivers prefer high triggering thresholds, which sometimes can not be realized with justifiable design effort by the triggering mechanism of the clamping bracket 16, ie the compression springs 44. By the side abutment surfaces 82 as a variant of a side support assembly according to the invention reliably prevent lateral triggering of the toe in the downhill position, very high release forces can be adjusted by appropriate heel machines (which usually can include much larger and stronger compression springs).

By holding the stop member 20 in its voltage applied to the front sole portion of the ski boot according to position FIGS. 2a to 2g In the first closed position, the advantage can also be achieved that the user can optically recognize that the touring binding 10 is not yet set in the second closed position to be described, in which the touring binding 10 is locked to prevent false triggering during the ascent. In this way, as well as further for the reason that in the first closed position, a pivoting of the ski boot for walking due to the blocked stop member 20 not at all is possible, the user is reliably reminded to transfer the touring binding 10 to the second closed position by a locking operation, which will be described below with reference to FIG FIGS. 3a to 3g is explained.

To adjust the touring binding 10 from the first closed position to the second closed position, the operating lever 50 is raised at its operating section 52 and in FIGS. 2b . 2e and 2f pivoted clockwise until it is in the position according to FIGS. 3a to 3g reached. In this case, the locking portion 56 of the operating lever 50 slides on the cam surface 58 until the locking portion 56 is disposed approximately between the pivot axis 48 of the operating lever 50 and a substantially vertically underlying portion of the cam surface 58. Thus, in the second closed position, a pivoting movement of the actuating lever 36 is blocked back into the open position. A during the pivotal movement of the operating lever 50 due to the cam surface 58 optionally still acting in the Z direction upward force on the pivot axis 48 can pivot the actuating lever 36 even further towards the closed position, whereby the end caps 40 pressed a bit further down be and the bearing pins 32 are pressed into particularly tight engagement with the bearing openings of the ski boot. In the second closed position of the ski boot is thus firmly locked to the touring binding 10 and unintentional triggering of the bond can be avoided.

In the second closed position, the positioning function or support function of the stop member 20 is no longer required and the stop member 20 can be folded forward to allow pivoting of the ski boot forward when walking. The second closed position is then a walking position of the touring binding 10.

In the first embodiment, the stop element 20 can automatically fold away in the second closed position to the front, as in the pivoting movement of the operating lever 50 from the first closed position to the second closed position and the support portion 60 of the operating lever 50 is pivoted away from the second mating support portion 88 of the stop member 20 and thus no longer blocks the pivotal movement of the stop member 20 forward, and there also also the support portion 72 of the control lever 66 immersed in the recess 86 of the stop member 20. The folding away of the stop member 20 forward may due to manual actuation by the hand or the floor of the user, due to a displacement movement by the forward pivoting ski boot at the first walking step or due to a previously explained, not shown in the drawings spring, which the stop element 20th biased forward, done. In the latter case, the folding away can be done automatically and thus for the user without additional operating effort.

In the in FIGS. 3a to 3g shown second user position, the user can use the touring binding 10 in a walking position, ie, for example, not shown in the figures heel machine can be placed in a walking position in which he releases a heel portion of the ski boot, so that the ski boot about the transverse axis Q forward and forward can pivot back without the stop member 20 would hinder this movement.

When adjusting the touring binding 10 from the second closed position back to the first closed position or the open position, the aforementioned operations and operations of the tour binding can be reversed. In particular, the support portion 60 of the operating lever 50 pushes when pivoting the operating lever 50 from the second closed position to the first closed position again against the second mating support portion 88 of the stop member 20 and lifts the stop member 20 from its folded forward position again until it returns to the upright position of the first closed position passes, in which it at the front portion of the ski boot strikes or at least in the immediate vicinity of the same is arranged. If the touring binding 10 is then adjusted to the open position by exerting a compressive force on the operating section 52 towards the ski, then the operating lever 50 also presses the second arm 46 of the actuating lever 36 toward the ski via the pivot axis 48. As a result, the pivot axis 48 slides in the slot 78 of the control lever 66 to its opposite (lower) stop and then begins to pivot the control lever 46 counterclockwise again. In this case, the support portion 72 of the control lever 66 pushes against the counter support portion 74 of the stop member 20 and takes over the limitation of the pivotal movement of the stop member 20, while the support portion 60 of the operating lever 50 lifts from the second counter support portion 88 of the stop member 20. At the same time, the end caps 40 preloaded by the compression springs 44 snap over the dead center and the clamping angles 16 pivot outwards, so that the bearing journals 32 release the ski boot.

With reference to FIGS. 4a to 6b Hereinafter, a second embodiment of the present invention will be explained.

A touring binding 110 of the second exemplary embodiment comprises a base plate 112, on which two clamping angles 116 are mounted with bearing journals 132 for pivotally holding a ski boot 125, wherein the clamping angles 116 can be adjusted by an actuating lever 136 between an open position, a first closed position and a second closed position. Furthermore, an operating lever 150 is also provided in the second embodiment, which is operable by the user for adjusting the touring binding 110. With regard to construction and function of the clamping bracket 116, the operating lever 136 and the operating lever 150, including its locking portion 156, the second embodiment corresponds to the first embodiment, so that these details are not repeated again and this explicitly to the description of the first

Reference is made.

In the second embodiment, the base plate 112 is not directly attached to a surface of a ski, but longitudinally displaceably guided in rails of an intermediate plate to be attached to the ski 113 and detectable for the operation of the touring binding 110 in a certain displacement position.

The touring binding 110 of the second embodiment has a left stop element 120a and a right stop element 120b. An abutment portion 121 a of the left stopper member 120 a is adapted to come into contact with a front left sole portion 123 of a touring ski boot 125, while a abutting portion 121 b of the right stopper member 120 b is adapted to contact a front right sole portion of the touring ski boot reach.

The abutment sections 121a, 121b can be formed such that each storage section has a rear abutment surface 162a or 162b and a lateral abutment surface 182a or 182b. The front sole portion of the ski boot can then be supported in a relatively large area both in its position in the X direction and in its position in the Y direction. The abutment surfaces 162a, 182a of the left stop element 120a and the abutment surfaces 162b, 182b of the right stop element 120b can merge into each other as a continuous surface, for example as part of a curved surface adapted to the outer contour of the ski boot.

The stop elements 120a, 120b are each pivotally supported on a bearing portion of the base plate 112, so that they are pivotable about a common axis 165 extending in the Y direction. In particular, they are between an upright position suitable for contact with a correctly positioned ski boot and one forward folded position pivoted. A left coupling element 166a is on the one hand pivotally connected to the left stop element 120a and on the other hand pivotally connected to the operating lever 150, in particular the locking portion 156 of the operating lever 150, pivotally connected. A right coupling element 166b is pivotally connected on the one hand to the right stop element 120b and on the other hand pivotally connected to the operating lever 150, in particular to the locking portion 156 of the operating lever 150, pivotally connected. Preferably, the pivot points of the coupling elements 166a, 166b are arranged with the stop elements 120a, 120b on a common axis Y7 extending in the Y direction and the pivot points of the coupling elements 166a, 166b with the operating lever 150 are also on a common, running in the Y direction Axis 169 arranged.

Hereinafter, the function of the touring binding 110 of the second embodiment will be explained in more detail. In addition, reference is expressly made to the above description of the first embodiment.

In the in FIGS. 4a and 4b shown opening position, the clamping bracket 116 are open and the actuating lever 136 is pivoted so that the operating lever 150 is at most approximated to the ski. The stop members 120a, 120b are in their upright position and provide a positioning aid for the touring ski boot 125. When entering the touring binding 110, the user can easily find the correct position by attaching a front or side sole portion 123 of the shoe 125 to the toe Stop elements 120a, 120b supported. The lateral bearing openings 127 of the ski boot 125 are then positioned ready for engagement with respect to the bearing journals 132, so that when the touring binding 110 is closed, the bearing journals 132 can easily engage in the bearing openings 127 of the ski boot 125.

After closing the clamping bracket 116, the touring binding 110 may be in the in FIGS. 5a and 5b shown first closed position. The first closed position may be a downhill position of the touring binding 110, ie an automatic heel unit, not shown in the drawings, can hold a heel portion of the touring ski boot 125, so that the shoe as a whole is firmly fixed to the ski. Since, however, the actuating lever 136 is pivoted during the transition from the open position to the first closed position, the operating lever 150 is substantially not pivoted, the stop elements 120a, 120b remain in contact in the upright position or at least in the immediate vicinity of the front or side sole sections 123 of the shoe 125 and block lateral displacement (in the Y direction) of the front portion of the ski boot 125. Thus, since the toe is substantially incapable of being released from the touring binding 110, a triggering behavior can be accomplished entirely by appropriate adjustment of a heel counter (not shown) so that the tripping behavior can be better defined and, in particular, higher tripping values can be achieved.

From the first closed position, the touring binding 110 in the in Figures 6a and 6b shown second closing position can be adjusted by the operating lever 150 is placed until the locking portion 156 is pushed approximately between the pivot axis 148 of the operating lever 150 and a substantially vertically below the pivot axis 148 arranged portion of a cam surface 158 of the base plate 112. Due to the pivotal movement of the operating lever 150 with respect to the actuating lever 136 and the coupling elements 166a, 166b are moved, in particular pulled forward so that the stop members 120a, 120b fold away to the front. In the exemplary embodiment, the coupling elements 166a, 166b are coupled to the locking section 156, which pivots forward during the transition from the first closed position to the second closed position, so that the stop elements 120a, 120b are also pulled forward.

Since the stop elements 120a, 120b in the second closed position after folded forward, the second closed position can be used as walking position of the touring binding 110, in which a heel portion of the ski boot 125 is released by a heel counter, so that the touring ski boot 125 can pivot about the axis of the bearing pin 132. This pivotal movement is no longer hindered by the folded away to the front stop elements 120a, 120b in the second closed position. Although the stop elements 120a, 120b in the second closed position can take no lateral support function more, an unwanted triggering of the touring binding 110 can be prevented in the second closed position in the manner already described with respect to the first embodiment, characterized in that between the pivot axis 148th and cam surface 158 pushed locking portion 156 blocks pivoting of the actuating lever 136 in the open position.

In the first and second embodiments, the rear abutment surfaces 62 and 162a, 162b have been formed on the same stopper member 20 and 120a, 120b, respectively, as adjacent surfaces. In a particularly simple variant, combination stop elements could in each case be used in both exemplary embodiments, which each have an abutment section which takes over both a longitudinal positioning of the ski boot and a lateral support of the ski boot. In particular, the stop elements could be formed as simple pins or projections. Due to the forward tapered contour of the ski boot basically any arranged in this section stopper element could allow both longitudinal positioning and lateral support.

With reference to the FIGS. 7a to 7d a third embodiment of the invention will be described below. The touring binding 210 of the third embodiment includes a base plate 212 for attachment to a ski, two brackets 216 for pivotally supporting a suitable touring ski boot, and a binding actuator assembly 218 with an actuating lever 236 and an operating lever 250 to move the clamping angle 216 between the open position and the first and second closed position and to additionally lock the touring binding 210 in a second closed position. With regard to the construction and function of the mechanisms for opening, closing and locking the clamping brackets 216 by means of the binding actuator assembly 218, reference is expressly made to the above description of the construction and function of the first embodiment, which is identical or correspondingly designed in this respect.

In the third embodiment, the invention aspect of the lateral support of the touring ski boot is realized in a particularly simple construction. A left stopper member 220a and a right stopper member 220b are fixedly connected to the base plate 212 and arranged to be in contact with a left side sole portion and a right side sole portion of a matching touring ski boot, respectively. The stop members 220a, 220b may be integrally formed with the base plate 212, or may be attached thereto in a suitable manner.

In contrast to the first and second embodiments, the stopper members 220a, 220b of the third embodiment have substantially no function for positioning the ski boot in the X direction, but serve to support the touring ski boot in the Y direction, that is, to prevent accidental side release of a front portion of touring ski boot. Accordingly, the stop elements 220a, 220b may be arranged in the region of the clamping brackets 216, as in FIGS FIGS. 7a to 7d is illustrated. In particular, the stop members 220a, 220b are disposed adjacent the journal 232, but are formed as separate elements to allow movement of the clamping brackets 216 to open and close the touring binding 210.

In the illustrated embodiment, each of the stop members 220a, 220b is disposed in a corresponding recess 217 of the associated clamping bracket 216. The recess 216 may be a through opening in the clamping angle 216 through which the stop element 220a, 220b passes. The stop elements 220a, 220b can thus be arranged almost in the same place as the pivotable clamping angle 216, without hindering the pivoting movement of the clamping bracket 216. In the FIGS. 7a to 7d It can be seen that in the exemplary embodiment, the stop elements are formed as from the base plate 212 of integrally upwardly projecting columns or pins, which pass through the through holes 217 in the clamping brackets 216.

A touring ski boot each facing contact surface 221 a of the left stop element 220a and a touring ski shoe facing contact surface 221 b of the right stop element 220b do not follow exactly the contour of the corresponding sole portion of a arranged in the correct driving position Toureskkischuhs, but each have chamfers. The beveled abutment surfaces 221 a, 221 b correspond approximately to the contour of a sole portion of a touring ski boot, which is pivoted to the corresponding stop element 220a or 220b out so that the heel of the ski boot is triggered by the heel counter. The tapered abutment surfaces 221 a, 221 b thus allow triggering of the heel portion of the shoe, but at the same time reliably prevent a triggering of the front portion of the shoe out of engagement with the bearing pin 232.

Thus, even in the touring binding 210 of the third embodiment, a triggering behavior and in particular a particularly high release threshold can be conveniently controlled by providing a corresponding heel and corresponding adjustment of the heel unit and the tripping behavior of the touring binding is not limited by the design limited triggering behavior of the terminal angle.

Although it has been clarified with reference to the third embodiment that the aspect of the lateral support of the ski boot can be realized independently of the positioning of the ski boot in the X direction, it is not excluded that, for example, the stop elements 220a, 220b described in the third embodiment can also take over a certain function of the positioning of the ski boot in the X direction. In particular, when the bearing openings of the ski boot are located in a front portion of the ski boot, in which the ski boot is already tapered, side support portions which come to rest in the vicinity of the bearing openings can simultaneously also act as stops for a forward shift of the ski boot in X- Serve direction and thus facilitate the correct positioning of the ski boot in ready to move position in the opening position of the touring binding.
