Description

The present invention relates to a touring binding for a touring gliding board, comprising a bearing assembly adapted to pivotally hold a gliding board shoe about a transverse sliding board transverse axis transverse to a gliding board longitudinal axis, a triggering mechanism having at least one movable control section which upon application of a force exceeding a predetermined tripping force executes a release movement on the touring binding, wherein the tour binding is adjusted in the direction of an open position, so that the sliding board shoe is released from the touring binding, a locking mechanism which is adjustable between an unlocked position in which the triggering movement of the actuating portion is possible, and a locking position in which the locking mechanism holds the adjusting portion in a locking position and blocks the triggering movement.

Touring bindings of this type are mounted on touring skis, particularly touring skis, splitboards, snowshoes or the like, to pivotally hold a shoe to the gliding board so that a heel portion of the shoe can lift off the shoe at each step of the skier. An example of a touring binding of the generic type is from the EP 0 199 098 A2 known.

Well-known tour bindings, such as those from the EP 0 199 098 A2 known touring ski binding, can be placed in a downhill position, in which the shoe is fixed not only in its front portion, but also in his heel section relative to the sliding board. In order to reduce the driver's risk of injury in the event of a fall during downhill, the triggering mechanism will open on impact predetermined rash release force exceeding force the touring binding to decouple the shoe from the sliding board.

On the other hand acts during a walking tour binding, in which the touring binding releases the heel portion of the shoe, the entire force exerted by the skier on the touring binding force only on the front portion of the touring binding, especially on the pivotal mounting of the shoe, making it especially difficult Ascending or, in accordance with sporty walking, can lead to an undesirable triggering of the release mechanism of the front portion of the touring binding. Unwanted triggering often involves time and loss of power for the tour operator, and can even be dangerous in some situations. With the locking mechanism, the well-known touring binding therefore blocks the function of the release mechanism in the walking position, so that an undesired triggering can be prevented. It is in the EP 0 199 098 in the locking position, the pivotal movement of an actuating lever, by means of which the bearing assembly is moved between the closed and the open position, blocked by a locking element in which the locking element between one end of the actuating lever and the ski is inserted.

In continuous use of the known touring binding has been shown that the reliability of the locking of the trigger mechanism depending on the intensity and duration of use can significantly decrease. In addition, it has been found that the reliability of the lock is subject to variations due to manufacturing tolerances of the touring binding, but above all due to design deviations between different shoe types. The resilience of the lock can therefore depend heavily on wear of the components or the shoe model used. However, especially in the field of athletic touring, so for example in touring racing, a reliable function of the locking mechanism is essential because unwanted triggering when climbing the mountain, especially in high-stress situations should be avoided at all costs.

The WO2007010392A2 discloses such a touring binding with vertical pivot axes.

Against this background, it is an object of the present invention to provide a touring binding of the type mentioned, which even after prolonged use and despite design or manufacturing-related variations in the dimensions of the touring binding and / or used Gleitbrettschuhs reliable locking of the trigger mechanism allows unwanted triggering to prevent.

The object is achieved according to the invention by a touring binding according to claim 1. By adjusting the locking position of the adjusting section using the position adjusting device according to the invention, an adjustment of the engagement between the triggering mechanism and the locking mechanism is made possible, with which wear-related, design-related or production-related deviations can be compensated.

This can be attributed to the fact that in the case of a trigger movement of the shoe is transmitted directly or indirectly via the trigger mechanism in the release movement of the actuating section. Occurs at one of the power transmission points within this chain of motion wear or a design or manufacturing-related deviation, for example, wear at a contact point between shoe and touring binding or when changing the shoe type, this will result in a slight change in the position of the adjusting section in the locked Position off. By means of the position adjusting device according to the invention, this slight displacement can be compensated for and it can be ensured that in the locking position the adjusting section is securely blocked by the locking mechanism at this locking position. Thus, the reliability of the locking mechanism can be improved and an undesirable triggering of the touring binding safely avoided even at high loads.

When in the present disclosure of a locking or a locking position of the touring ski binding is mentioned, in which an undesirable triggering of the bond is prevented, this may mean on the one hand that a release occurs only when a release force occurs, which is significantly greater than the triggering force necessary for triggering the touring binding in unlocked condition (eg during departure in the downhill position of the touring binding). On the other hand, it is conceivable that a release in the locked state without damaging the touring binding or the shoe is not possible at all. In other words, the position adjusting device according to the invention thus allows an adjustment or readjustment of the force (locking release force), which opposes the touring binding in the locked state of a forced release, including the case that the release in the locked state only under damage to the binding or Shoe is possible.

In one preferred embodiment of the invention, the position adjusting means comprises a rotatably supported position adjusting member, wherein the locking position of the adjusting portion changes in accordance with a rotational angle of the position adjusting member. A rotatable position adjustment allows easy and accurate adjustment of the locking position by corresponding rotation of the position adjustment. The rotatable position adjusting element may have a section which is eccentric to the axis of rotation, so that upon rotation of the position adjusting element the eccentric section effects a displacement of the locking position of the adjusting section. The Positionseinstellelement can thus be made as a particularly simple and lightweight component in particular from one piece.

A rotatable position adjusting element with a section eccentric to the axis of rotation can furthermore have a center axis which is centered on the axis of rotation Section, wherein the adjusting portion on one of the two portions, the eccentric portion or the central portion, supported, and wherein the locking mechanism is supported on the other portion. With such an embodiment, the rotatable position adjusting member may be in contact with the adjusting portion on the one hand and with the locking mechanism on the other hand to easily adjust the relative position of the adjusting portion with respect to the locking mechanism.

The locking mechanism may include a locking member engageable with at least one predetermined locking position to lock the touring binding, the position adjustment mechanism configured to adjust the locking position of the adjustment portion that the adjustment portion occupies when the locking member is in the at least one predetermined locking position , Thus, even if a locking element of the locking mechanism is adjustable in several different locking positions in order to set different locking levels (different locking triggering forces), the position adjustment device according to the invention allows the setting of the locking position of the adjusting section for at least one of these locking steps, so that in this locking step the adjusting section can assume different locking positions.

In a further embodiment of the invention it is provided that the locking mechanism comprises a locking element which is pivotally supported by the position adjustment on the adjusting portion or on the touring binding, wherein the locking member is placed in the unlocked position of the locking mechanism in a first pivot position in which it Tripping movement of the actuating portion permits, and is placed in the locking position of the locking mechanism in a second pivot position, in which it holds the adjusting portion in its locking position and the release movement blocked. This embodiment offers the constructional advantage that the position adjustment can have a first function for pivotally mounting the locking element for adjusting the locking element between the unlocking position and the locking position and a second function for setting the locking position of the actuating portion according to the invention. This dual function allows component savings and weight savings.

Alternatively or additionally, the rotatable position setting element can have a double function as a pivot axis of the adjusting section as well as a means for adjusting the locking position of the adjusting section. The pivot axis of the adjusting portion, which is formed in this embodiment by the position adjusting, it may be a pivot axis about which the actuating portion in triggering the triggering mechanism performs the tripping movement, but may also be a pivot axis, on which a locking element of the locking mechanism pivotally mounted on the Positioning section is mounted so that the locking element is pivotable on the adjusting section between unlocked position and locking position.

A particularly stable mounting of the rotatable position setting element can be achieved in an embodiment variant of the invention in which an eccentric section is arranged between two central sections on the position adjustment element and / or a centric section is arranged between two eccentric sections. The eccentrically held component, such as the adjusting portion, and the centrally held component, such as the locking mechanism can then be stably coupled to each other at the Positionseinstellelement, for example, by one of the two components is mounted on two axially spaced portions of Positionsseinstellelements, and another of the two components is mounted on a portion of the position adjusting element arranged between the bearing sections of the one component.

In the above-described variants, when eccentric and central portions are axially arranged on the position adjusting member, preferably, the outer diameter of the portions increases from a first longitudinal end of the position adjusting member toward an opposite, second longitudinal end of the position adjusting member from one section to the other and at the position adjusting member mounted components each have bearing openings which are adapted to the diameter of the associated eccentric or central sections. The Positionseinstellelement can then be inserted with the first longitudinal end ahead, in the bearing openings of the components until all the bearing openings of the components fit their centric or eccentric sections enclose. In this way, a particularly simple installation can be made possible.

To set the locking position of the adjustment, the position adjustment can be adjusted by hand or by means of a tool. If a rotatable position adjustment element is used, it preferably has a tool engagement section for rotational actuation of the position adjustment element by means of a suitable tool. The user can then make the desired adjustment by means of a tool.

Preferably, the touring binding further comprises a locking device which is adjustable between a release position in which an adjustment movement of the position adjusting is possible, and a locking position in which the adjusting movement of the position adjustment is blocked. It can thereby be achieved that the locking position of the adjusting section set by the position setting device is not inadvertently adjusted during the use of the touring binding by possible vibrations or the like, so that a precise adjustment of the triggering mechanism or the locking mechanism is permanently ensured.

The locking device may be in the locking position form-locking with a position setting of the position adjustment, in particular with the above-mentioned, rotatable Positionseinstellelement, engage to block movement of the Positionseinstellelements. On the one hand, the positive locking is particularly reliable and on the other hand offers the possibility of a discrete adjustment of the position adjustment device, which makes it possible to adjust the locking position of the adjusting section in a finite number of defined setting stages that is easy to handle for the user. The stepwise adjustment of the position adjuster may also be advantageously used to adjust the position adjuster, e.g. When changing the shoe type to quickly adjust between defined setting positions, so that an advantageous setting of the position adjustment can be easily recovered.

With particular advantage, a touring binding of the present invention is applicable in connection with a bearing arrangement comprising two bearing sections arranged on different sides of the sliding board longitudinal axis, which are adapted to engage in a closed position of the touring binding opposite lateral abutment portions of a Gleitbrettschuhs to the Shoe around the Gleitbrettquerachse pivotally to keep the touring binding, wherein the bearing portions are each formed at a bearing angle, which are held for adjusting the touring binding between the closed position and the open position pivotally connected to the touring binding. In this, known per se type of bearing assembly wear of the bearing sections or the abutment portions of the sliding board shoe or a replacement of the Gleitbrettschuhs come to slight changes in the distance between the two bearing sections. In this type of binding, because the bearing angles form part of the triggering mechanism by pivoting the bearing angles outwardly when a force exceeding a predetermined release force is exerted to release the sliding board shoe therebetween, it is for reliable locking of the trigger mechanism requires that the latch mechanism securely lock the bearing angles in the closed position regardless of any slight positional deviations of the bearing angles due to the wear or change of the ski boot. The position adjustment device according to the invention makes it possible to adapt the locking mechanism or the triggering mechanism to such positional fluctuations.

In the above application of the tour binding according to the invention on the known type of bearing arrangement with pivotable bearing angles, the adjusting portion, the locking position is adjustable by the position adjusting device according to the invention, preferably arranged on an actuating element of an actuating arrangement which controls the movement of the actuating element in a pivoting movement of the bearing angle converts and converts a pivoting movement of the bearing angle in a movement of the actuating element. Thus, in this variant of the invention, the adjusting portion is not provided directly on the bearing angles, but on a motion-coupled with the bearing angles actuator, which may be in particular an actuator for manual adjustment of the bearing angle between the closed position and the open position. Thus, the advantage is achieved that the locking of the touring binding with only one locking element is possible, which cooperates with the actuating element, and thus the position adjustment according to the invention must be made only on the adjusting portion of the actuating element and not separately for each bearing angle.

In the FIGS. 1 to 8 is shown a front unit 10 of a touring ski binding, with which a front portion of a touring ski boot, not shown, can be held. In general, the touring ski binding further includes a heel unit, also not shown, which can engage a heel portion of the touring ski boot.

A base portion 12 of the toe binding front assembly 10 has attachment means for securing the front unit 10 to the surface of a ski, not shown. The fastening means may be formed by a plurality of holes 14 through which screws 16 to be screwed into the ski can be guided. The fastening means define a mounting position of the front unit 10 on a touring ski and thus define an X-direction along a longitudinal axis L, the a sliding board longitudinal axis, a Y-direction which is parallel to the Skiebene and orthogonal to the X-direction, and a Z-direction, which is orthogonal to the X-direction and the Y-direction, fixed.

At the base portion 12, a left bearing angle 18l and a right bearing angle 18r are pivotally mounted on different sides of a vertical center plane containing the longitudinal axis L and extending parallel to the Z direction by pivot axes 20l, 20r extending in the X direction, respectively. At their upper free ends, the bearing angles 18l, 18r bearing portions 22l, 22r, which together define a transverse to the X-direction pivot axis Q for a ski boot, not shown, and which are adapted to engage with corresponding abutment elements of the ski boot, in order to hold the ski boot pivotably about the common pivot axis Q on the front unit 10. In the exemplary embodiment, the bearing elements 22l, 22r are formed by inwardly projecting journals which are adapted to engage in corresponding bearing recesses in front lateral portions of the ski boot.

Actuating arms 24l, 24r of the bearing angles 18l, 18r which are remote from the bearing sections 22l, 22r essentially run towards one another and are in contact with one another at end caps 26l, 26r of the actuating limbs 24l, 24r. The length of the actuating legs 24l, 24r from their respective pivot axis 20l, 20r to the end caps 26l, 26r is variable by a movable mounting of the end caps 26l, 26r with respect to the bearing angles 18l, 18r. Tension springs 28l, 28r respectively act between the end caps 26l, 26r and the bearing angles 18l, 18r to bias the end caps 26l, 26r into contact with each other. The tension springs 28l, 18r hold the bearing angles 18l, 18r in this way in two stable states, namely a first state in which the point of contact between the end caps 26l, 26r is located below a connecting line between the pivot axes 20l, 20r, so that the bearing portions 22l, 22r by the tension springs 28l, 28r in the direction of a mutual Approach biased and are clamped in engagement with the abutment elements of the ski boot, and a second state in which the contact point between the end caps 261, 26r above a connecting line between the pivot axes 20l, 20r is arranged so that the bearing angle 18l, 18r in the be stretched opposite direction, so that the two bearing portions 22l, 22r pressed away from each other and release the ski boot. The first state forms a closed position of the front unit 10, while the second state corresponds to an open position of the front unit 10.

In a manner known per se, the pivotal movement of the bearing angles 181, 18r between the closed position and the open position can be coupled to a pivotal movement of an actuating lever 30, by a first end 32 of the actuating lever 30 with the two end caps 26l, 26r is coupled in motion, and the actuating lever 30 is pivotally mounted on the base portion 12 on a bearing axis 34 extending transversely to the X direction, so that a pivoting movement of the lever 30 about the bearing axis 34 into a substantially vertical movement of the two end caps 26l, 26r and thus a pivoting movement of the bearing angle 18l, 18r about the pivot axes 20l, 20r is implemented. On the other hand, the coupling between the operating lever 30 and the end caps 26l, 26r causes pivotal movement of the bearing angles 18l, 18r to be translated into pivotal movement of the lever 30.

At a second end 36 of the actuating lever 30, a locking lever 40 is pivotally mounted about a transversely to the X direction, in particular substantially in the Y direction extending pivot axis 38, so that this between a in FIG. 8 shown unlocking position and a in FIG. 7 shown locking position is pivotable. At an operating portion 42, the locking lever 40 can be manually operated by the skier's hand or the tip of a ski pole to move the locking lever 40 between the unlocking position and the locking position. Furthermore, the locking lever a locking portion 44 which blocks in the locking position of the locking lever 40 in a manner to be described in more detail later pivotal movement of the actuating lever 30 and in the unlocked position, the pivoting movement of the actuating lever 30 allows.

In the FIGS. 7 and 8 is the front unit 10 respectively shown in the closed position, in which when using the touring binding a not shown ski boot with the bearing portions 22l, 22r is in Einirff. Is the locking lever 40 according to FIG. 8 pivoted in the unlocked position, so the locking lever 40 abuts against a stop on the actuating lever 30. Further actuation of the locking lever 40 in the unlocking position direction is thus implemented in a pivoting operation of the actuating lever 30 about the bearing axis 34, so that the first end 32 of the actuating lever 30, the end caps 26l, 26r moved upward and the bearing bracket 18l, 18r are pivoted outwardly to move the front unit 10 to the open position.

Conversely, in the unlocked closed position according to FIG. 8 a trigger mechanism of the front unit 10 are effective, which is formed by the bearing bracket 18l, 18r with the tension springs 28l, 28r, the actuating lever 30 and the locking lever 40. Upon exertion of a predetermined release force exceeding force from the ski boot on the bearing portions 22l, 22r, the bearing bracket 18l, 18r against the tension of the tension springs 28l, 28r displaced to the outside. This movement can be assisted by the fact that the bearing elements 22l, 22r are designed as projecting pins with conically tapering ends and interact with corresponding at least partially conical bearing openings of the ski boot. The forced movement of the bearing angles 18l, 18r at the triggering leads to a forced pivotal movement of the actuating lever 30, which provides a movable positioning portion in the sense of the present invention.

As in FIGS. 7 and 8 can be seen, when a triggering force is exerted on the front unit 10, a release movement of the actuating lever 30 (here a downward movement of the second end 36 of the actuating lever 30 towards the ski) is possible because the locking portion 44 of the locking lever 40 does not block this pivotal movement. If, however, the locking lever 40 is pivoted into the locking position ( FIG. 7 ), the locking portion 44 is inserted into the pivot angle of the actuating lever 30, so that the actuating lever 30 is blocked and is held in a locking position. Even with the action of a force exceeding a predetermined release force, ie in particular when a force is exerted on the front unit 10, which in the case of a descent in the unlocked position would trigger the touring binding, the actuating lever 30 can no longer pivot into the open position , so that the bearing portions 22l, 22r can no longer disengage from the abutment elements of the ski boot. A release can then take place when a significantly higher locking release force is exceeded, for example due to elastic deformation of the clamping bracket 18L, 18R or the actuating lever 30, or a triggering can not be possible at all without damaging the binding or the shoe.

In the locking position, the locking portion 44 on a binding or skifesten section, here a projection 48 of the base portion 12, supported. In order to allow different locking levels in which the lock is differently stable (different lock release forces) and the bearing elements 22L, 22R are pressed against the counter-bearing elements of the shoe with different force, a plurality of locking positions may be provided for the locking lever 40, in particular one Plural of depressions on the locking portion 44 and / or be arranged on the projection 48, which engage with a detent. In the embodiment are at the Bottom 49 of the locking portion 44 a plurality of not visible in the figures, provided in the Y-direction notches. This allows, for example, the setting of the locking lever 40 in a first locking position (eg according to FIG. 4 ) with a lower locking strength for safety-oriented walking, in which an emergency release with correspondingly heavy load is still possible, or in a second locking position (eg according to FIG. 7 ) with higher locking strength, in which for racing-oriented walking triggering is hardly or no longer possible.

The movement of the actuating element 30 in the direction of the open position is blocked by the locking portion 44 of the locking lever 40, which is supported on the one hand via the pivot axis 38 on the actuating lever 30 and on the other hand on the bond-resistant or skifesten section, here the projection 48 of the base portion 12 is supported. The movement of the actuating lever 30 in the direction of the closed position, on the other hand, is transmitted via the bearing angles 181, 18r and the bearing sections 22l, 22r into the abutment portions of the ski boot and thus blocked only by the shoe. If it comes along this motion transmission chain to wear, or to manufacturing or design-related fluctuations, eg wear of the bearing elements 22l, 22r or the abutment elements of the ski boot or an exchange of the model of the ski boot, the position of the stopper changes, at which the actuating lever 30 is blocked in a movement in the closed position. In this way, a game arises on the actuating lever 30 in the locking position. This game allows a corresponding game in the pivotal movement of the bearing bracket 18l, 18r and thus a game in engagement between the bearing elements 22l, 22r and the abutment elements of the ski boot. Thus, the reliability of the lock is reduced and there is a risk that the ski boot is disengaged from the bearing members 22l, 22r, although the front unit 10 is in the lock position. According to the invention, the embodiment has a position adjustment device 50, by means of which the locking position of the actuating lever 30 is adjustable so that the above-mentioned game is reduced and in particular completely canceled. The position adjustment device 50 of the embodiment comprises a rotatable position adjustment element in the form of an eccentric axis 52, which forms the pivot axis 38 for the pivotable connection between the locking lever 40 and the actuating lever 30. As will be described in more detail below, by the eccentric axis 52 on the one hand by their rotation, the position of one of the two levers of locking lever 40 and actuating lever 30 with respect to the pivot axis 38 change and on the other hand, the eccentric axis 52, the technical means for a pivot bearing between the locking lever 40 and actuating lever 30 provide.

In the FIG. 3 in perspective and in FIGS. 5 and 6 Position adjustment device shown in section comprises as Exposing axis adjustment position 52 which is rotatable about the pivot axis 38 and at axially different sections at least one centric to the pivot axis 38 peripheral portion and at least one eccentric to the rotation axis 38 peripheral portion. In the exemplary embodiment, in the axial direction from a first longitudinal end 54 to a second longitudinal end 56: A first centric section 58, an eccentric section 60 whose outer circumference surrounds the outer circumference of the first central section 58 in a radial section of the eccentric axis 52, a second centric section 62, whose outer periphery in a radial section of the eccentric axis 52 surrounds the outer periphery of the eccentric portion 60, and a head portion 64th

To enable the position adjustment, the at least one central portion may be supported on one of the two levers of the locking lever 40 and the operating lever 30, while the at least one eccentric portion is supported on the other of the two levers 30, 40 can be. In the exemplary embodiment, the second end 36 of the actuating lever 30 is arranged in a recess 66 of the locking lever 40, so that on both sides of the recess 66 arranged bearing portions 68, 70 of the locking lever 40 store the first central portion 58 and the second central portion 62 of the eccentric axis 52, while the eccentric portion 60 of the eccentric axis 52 between the bearing portions 68, 70 of the locking lever 40 is mounted on a bearing portion 72 of the actuating lever 30.

The head portion 64 of the eccentric axis 52 may be configured for manual operation. Thus, it may have a tool engaging portion 73 in the form of a slot for actuation by means of a screwdriver or other design, e.g. for the operation by means of a Phillips screwdriver, a Allen key or the like. The head portion may surround the outer circumference of the second eccentric portion 62 in a radial sectional plane so that the outer circumference or diameter of the eccentric axis 52 gradually increases from the first longitudinal end 54 to the head portion 64 at each of the portions 58, 60, 62, 64. As a result, a simple assembly of the eccentric axis 52 is made possible, which can then be used with the first longitudinal end 54 ahead of the bearing portion 70 with the largest diameter in all three bearing sections 68, 70, 72.

Upon rotation of the eccentric axis 52 by rotation of the head portion 64, the central portions 58, 62 and preferably also the centrally disposed head portion 64 rotate concentrically with the pivot axis 38 so that the position of the locking lever 40 with respect to the pivot axis 38 remains unchanged. At the same time, however, shifts the mounted on the eccentric portion 60 second end 32 of the actuating lever 30 relative to the bearing axis 38 and thus also relative to the locking lever 40. Since the locking lever 40 limits the pivoting movement of the actuating lever 30 in the locking position, by the rotation of the eccentric axis 52 also the locking position the actuating lever 30 is adjusted, ie the position in which the actuating lever 30 is held in the locking position of the locking lever 40 of the locking lever 40.

Preferably, the front unit 10 further comprises a locking device 74, which can be brought into positive engagement with the eccentric axis 52 in order to prevent an unwanted adjustment of the eccentric axis 52. In the illustrated embodiment, the locking device 74 is formed by a bolt which can engage in a matching notch 78 on the eccentric axis 52.

Preferably, the bolt is designed as a screw 76 which can be screwed into a threaded bore 80, which runs parallel to the pivot axis 38 and is arranged at a distance from the pivot axis 38. The screw 76 has at its head portion a tool engaging portion 79, here a Phillips for actuation by means of a Phillips screwdriver on.

The head portion 64 of the eccentric axis 52 has distributed in the circumferential direction a plurality of the above-mentioned notches 78, in the exemplary embodiment, five notches 78 whose contour corresponds to the outer contour of the screw 76. If the screw 76 is a countersunk head head screw such that the head can be received in a corresponding conical valley 82 of the threaded bore 80 and does not protrude beyond the outer surface of the lock lever 40, the notches 78 preferably also have a matching tapered section shape that a tapered portion of the head of the screw 76 can fit snugly in one of the notches 78 and both the head of the screw 76 and the head portion 64 of the eccentric axis 52 are received in the lock lever 40 so that they do not project beyond the surface thereof.

Hereinafter, the operation and the function of the front unit 10 of the touring binding will be explained. To get into the touring binding of the Operating lever 30 is pivoted by pressure on the operating portion 42 so that the second end 36 and the locking lever 40 are moved towards the ski, so that the bearing angle 181, 18r open and allow the positioning of the ski boot between the bearing elements 22l, 22r (open position) ,

After inserting the ski boot bearing angles are 18l, 18r from the open position in the in FIG. 8 pivoted closed position shown by a sole portion of the ski boot presses on the first end 32 of the actuating lever 30 and thus the end caps 26l, 26r presses under the connecting line between the pivot axes 20l, 20r, so that the tension springs 28l, 28r the bearing angle 181, 18r in clamp the closed position and the bearing portions 22l, 22r are pressed into contact with the abutment elements of the ski boot. At the same time pivots the actuating lever 30 so that the second end 36 and the locking lever 40 mounted thereon stand out from the ski. In this unlocked, closed position, the front unit 10 is set up for a downhill run, in which additionally a heel unit of the touring binding should keep a heel portion of the ski boot fixed. Upon the occurrence of a predetermined release force exceeding force on the bearing portions 20l, 20r, eg during a fall, the bearing bracket 18l, 18r displaced to the outside, wherein the corresponding pivotal movement of the actuating lever 30 is not blocked by the locking lever 40.

For a walking binding arrangement, in which a heel unit preferably releases the heel portion of the ski boot, so that the ski boot can pivot about the transverse axis Q, the front unit 10 can fit into the in FIG. 7 shown locking position by the locking lever 40 is pivoted so that the locking portion 44 aufschiebt the projection 48. The second end 36 of the actuating lever 30 can then no longer approach the ski, ie no longer move into the open position, so that a trigger the front unit 10 is prevented. If a plurality of locking stages are provided, then the locking lever 40 can be pivoted in the walking position into a desired locking position for setting the desired locking level.

In the case of the wear, design or manufacturing-related changes already mentioned, however, it may happen that the locking position of the actuating lever 30 predetermined by the locking section 44 deviates from that position of the actuating lever 30 in which the tension springs 28l, 28r bias the actuating lever 30. For example, if the distance between the abutment elements of the shoe for the reasons mentioned above is too small, so the operating lever 30 a game between the stop on the abutment elements of the ski boot on the one hand and the stop of the locking portion 44, so that the bearing portions 22l, 22r within This game are mobile and an unwanted triggering can take place. With the position adjusting device according to the invention, this play can be compensated by the eccentric axis 52 is rotated so that the actuating lever 30 is moved relative to the locking lever 40 in the closed position.

On the other hand, if the distance between the abutment elements of the shoe is too large, the second end 36 of the actuating lever 30 in the closed position is approached too far to the ski, so that the locking portion 44 is no longer completely pushed between the second end 36 and the projection 48 can be and a complete adjustment of the locking lever 40 in the locked position is no longer readily possible. By rotation of the eccentric axis 52, the relative position between the second end 32 of the actuating lever 30 and the locking lever 40 can then be adapted again so that the locking lever 40 can be put back into the locking position.

If the locking lever 40 is adjustable for setting different locking levels (locking strengths or locking triggering forces) into different locking positions, it can be achieved by rotating the eccentric axis 52 in one direction so that the locking force is increased in all locking levels or in all locking levels is reduced.

To rotate the eccentric axis 52 for the position adjustment according to the invention, which can be done either in the locked position or in the unlocked position of the locking lever 40, in the exemplary embodiment, first the screw 76 to be solved so far that the head of the screw 76 from the positive engagement with the corresponding notch 78 is lifted out. If substantially only the conical head of the screw 76 is engaged with the notch 78, this has the advantage that the screw 76 need not be completely unscrewed from the threaded hole 80, but only so far until the head of the screw 76 from Head portion 64 of the eccentric axis 52 lifts. The eccentric axis 52 can then be rotated by the desired amount until the next notch 78, whereupon the screw 76 can be tightened again. According to the number of notches 78, an adjustment of the locking position of the operating lever 30 in a predetermined number of discrete stages is possible in this way. Thus, a quick adjustment of the front unit 10 to predetermined types of ski boots can be made because the adjustment positions can be conveniently located.

The invention is not limited to the embodiment described above. Thus, in the exemplary embodiment, a setting section of the triggering mechanism of the actuating lever 30, in particular a second end 36 of the actuating lever 30, was used. However, the positioning portion may be any movable element of the front unit that is forcibly moved upon release of the binding, for example, the bearing angle. Also at these sections, the inventive Position setting make the position adjustment of the locking position. Furthermore, the triggering of the front unit in further variants of the invention can not take place directly on the bearing arrangement, which supports the ski boot pivotably about the transverse axis, but on another binding part, for example on a coupling section between the ski boot and a pivotally mounted frame of a frame binding.

In a further embodiment of the invention, the actuating lever, which the bearing assembly (in particular the bearing bracket 18 L, 18 R) and the locking mechanism (in particular the locking lever 40) coupled to transmit motion, formed from at least two mutually movably held sections, the Positionseinstelleinrichtung the invention between the Subsections of the actuating lever acts. Between the sections, a further, separate from the tension springs 28L, 28R, elastic arrangement may be arranged, so that a movement of the two sections relative to each other acts against the resistance of this elastic means. The position adjusting means may in this case change a biasing force of the elastic means, so that the force with which the touring binding is biased into the locking position can be changed. Alternatively or additionally, the position adjusting device may have a one-sided stop, which limits the distance between the sections on one side.
