Definitions
- the invention relates to a ski binding that is suitable for touring skiers and freeriders and ensures safe release at low weight in the event of a fall.
- ski bindings For touring enthusiasts and freeriders there is a desire for ski bindings with low weight. To ski down the ski boot is firmly clamped as between other ski bindings between a toe holder and a heel holder. For walking or climbing the connection with the ski in the heel area of the shoe is released, so that the shoe can still pivot around a lying in the area of the toe holder transverse axis when still existing connection with the toe. Bindings are known, for example from the WO 2007/060219 A1 and the EP 2 329 864 A2 in which the toe holder and the heel holder are connected to one another via a touring plate.
- the touring plate is detachably connected to the ski in the region of the heel holder, so that in the released state the toe plate and the heel holder can pivot together about the said transverse axis.
- bindings were developed that do without a touring plate.
- the heel holder also remains connected to go with the ski, while the connection of the ski boot and heel holder is released.
- the pivot required for walking is usually formed directly between the ski boot and the toe holder by the toe holder engages transversely in recordings of the ski boot.
- the heel holder has freely projecting support pins, which engage in corresponding recesses in the heel area of the ski boot and are movable for releasing against spring force from engagement with the ski boot.
- the support pins firmly hold the ski boot in the heel area on the ski, but such that there remains a clearance between the underside of the ski boot and the top of the ski to prevent plugging by snow.
- the ski boot is thus supported in the heel area in the vertical direction towards the ski on the support pins and is supported by the support pins in the opposite direction held.
- the release of the connection to unbuckle the ski or to go, designed with difficulty. Furthermore, a safe release in the event of a fall is not guaranteed with the desirable security.
- the invention is based on a ski binding which has a toe holder for holding a front region of a shoe and a heel holder for holding a rear region of the shoe.
- the heel holder comprises a base which is connected to a ski or can be connected by mounting with the ski.
- the base is advantageously flat, such as plate or rail.
- the heel holder further comprises a bearing structure, which projects in a vertical direction of the binding from the base, and a projecting support means, on which the rear portion of the shoe is supported in the vertical direction, so that when connected to the ski base at least in the rear shoe area in the supported state a clear distance remains between shoe and ski. When the shoe is supported over the base, this includes leaving a clearance between the shoe and the base.
- a plug through snow is counteracted and facilitates the change from walking to skiing on downhill.
- the clear distance is preferably at least one millimeter.
- the heel holder is for closing and opening the binding from a release state into a closed state and from the closed state again in the release state can be transferred.
- the heel holder can at least as far as the use of the ski, be firmly connected to the ski, so it must not be solved for walking with buckled ski from the ski, as is the case with touring bindings with swivel touring plate.
- a detachable and in the dissolved state movably connected to the ski tour plate can be omitted.
- the ski binding according to the invention can therefore advantageously be a tour-suitable, diskless ski binding.
- the toe holder is designed so that it holds the shoe in the front shoe area for walking with strapped ski movable, preferably pivotally, preferably by forming a joint.
- the toe holder can like a toe holder known bindings, such as the touring binding of EP 0 199 098 B1 be formed accordingly.
- He can movable, for example, pivotable engagement member for forming a joint, preferably rotary joint, directly with the shoe. It can also be pivotably connected to the ski for the pivoting mobility of the shoe itself.
- it has a movable left engaging member and a movable right engaging member which form with the shoe laterally shaped or joined engagement counterparts a hinge.
- the axis of rotation of the rotary joint is preferably a transverse axis of the binding, that is to say an axis which extends transversely to the vertical direction and transversely to a longitudinal direction of the binding pointing from the heel holder to the toe holder.
- the left and right engagement members may be pivotally connected to the base of the toe holder. Preferably, they are pivotable about an axis pointing in the longitudinal direction.
- the toe holder further comprises, in preferred embodiments, a spring device against the restoring spring force of which the at least one engagement member or preferably a plurality of engagement members of the toe holder is or are movable from a closed position in which they can hold the shoe in a release position.
- the heel holder in addition to the support means on a hold-down, which is relative to the bearing structure between a closing state of the heel holder corresponding closing position and the release state of the heel holder corresponding release position reciprocally movable, preferably pivotally, the shoe in the closed position on the Hold down support device resting and release it in the release position.
- the heel holder comprises a spring device which has at least one hold-down spring, against the restoring force of which the hold-down device is movable from the closed position into the release position.
- the hold-down device is preferably designed such that it presses in the closed position from above onto an upper side of the shoe which is free in the rear shoe area, for example an upper side of a projecting shoe sole, and thereby the underside of the shoe onto the support device.
- the mode of operation and also the shape of the hold-down device according to the invention can correspond to the holding down of the shoe to the functioning of a sole holder of tour-suitable safety bindings, as described, for example, in US Pat EP 2 329 864 A2 are known.
- An advantage of a heel holder with a support device and a hold-down device is that the heel holder has a good tilting rigidity, in particular on a descent, since the heel holder by the support means is not or substantially not transverse to a skiing direction can move and is additionally stretched simultaneously towards the ski surface.
- a distance between the support means and the hold-down may be fixed, at least in the situation where the support means and the hold-down hold the ski boot in a riding position on the ski.
- the distance corresponds to a distance between an engagement region for the hold-down device and an engagement region of the support device on the ski boot sole.
- the support device and the hold-down device are essentially not elastically deformable, but are designed so that they are resistant to bending.
- a snow span height of the heel holder may be, for example, about 6 mm.
- the snow span height is to be understood as meaning a height of the snow plug which is formed, for example, between the base of the heel holder and the ski boot sole.
- the heel holder or downholder reliably closes up to the mentioned snow span height of approx. 6 mm.
- the support device can already enter into a supporting connection with the ski boot, so that the ski boot is held securely in the heel holder. Decreases the height of the snow plug, the spring means of the heel holder and the hold-down spring, so to speak, "hold down" the hold-down until at a height of the snow plug of 0 mm, the ski boot stands directly on the base.
- the invention makes it possible to combine the significant advantage of diskless touring bindings, namely their low weight, with increased triggering safety and, for the downhill ride, advantageously rigid mounting of the boot.
- the invention separates the function of supporting lightly spaced from the ski and the base, if it extends under the support means of the function of holding down by providing a supporting support means and a hold down holddown, which ensures that the shoe is pressed on the support means with the binding closed.
- the shoe is held stiffer than in the known plateless touring bindings due to the interaction of hold-down and support means in the closed state of the heel holder.
- the support means and the hold-down device are preferably designed so that the hold-down presses directly on the shoe and this directly on the support means, preferably presses from above.
- the support device is relieved of its double function, which it must meet in the diskless touring bindings of the type mentioned. Preferably, it only has to fulfill its actual function, the support function.
- the binding according to the invention is also easier to handle, since the tedious opening of the support device when changing from shutdown to walking with buckled ski eliminated and instead only one of the support function free hold down from the closed position must be moved to the release position.
- the support means may project upwardly from the base in the form of a support structure exposing the shoe, such as a pin, embodiments are preferred in which the support means above the ski or above the base, if the base itself extends longitudinally on the toe holder beyond the bearing structure, and in such embodiments with a clearance to the base, projecting towards the toe holder.
- the support device protrudes from the bearing structure.
- the support device projects from a closing unit which comprises the hold-down device.
- the support means is movable relative to the base between an active position and an inactive position back and forth.
- the heel holder for example, on an outer side having a lever which is connected to the support means and can be pivoted together with the support means.
- the support device assumes the active position, the shoe can be supported with its rear region on the support device.
- the support device assumes the inactive position, the shoe is free of the support device and can be pushed down to the top of the ski or the base when walking.
- the mobility between the active position and the inactive position may in particular be a pivoting mobility or a translatory mobility or comprise such a mobility.
- the support means can be reciprocated between the two positions, together with the hold-down or the bearing structure.
- the word “or” is always understood by the invention in the usual logical sense of an “inclusive or”, thus encompassing both the meaning of "either ... or” and the meaning of "and” as far as from the respective concrete context can not exclusively give only one of these two meanings.
- the bearing structure between the active position and the inactive position can be moved back and forth.
- the support means may also be arranged to be movable to different inactive positions.
- the different inactive positions all have the common characteristic that, when the support device is in the respective inactive position, the shoe can be moved freely from the support device to the ski or the base or any other contact point located at the top of the ski. In the inactive position or the different inactive positions, the support device can at least not exercise a support function for the shoe with respect to the vertical direction.
- the support means can advantageously also be supported directly on the bearing structure in the vertical direction. It can be molded in one piece with the bearing structure, for example as an injection-molded part made of plastic. However, it may instead be immovably joined to the bearing structure, for example by means of a screw connection or adhesive connection or another suitable joint connection.
- the support means is transversely movable relative to the bearing structure, ie transversely to the longitudinal direction and vertical direction of the bond, for example orthogonal to the longitudinal direction and the vertical direction.
- the support means may include as said plateless touring bindings projecting from the bearing structure first support pin and projecting from the bearing structure second support pin which can cooperate with correspondingly formed in the rear shoes, by the first and the second support pin in each case in a corresponding receptacle in the rear Protected portion of such a shoe when the shoe is supported on the support means.
- at least one of the support pins may be movable transversely relative to the bearing structure and the other of the support pins, thereby varying a distance measured transversely between the support pins.
- both the first and the second support pin are transversely movable relative to the bearing structure.
- the respective transversely movable support pin must not be movable against a restoring spring force, since the support device according to the invention in the closed state of the heel holder is free of the function of holding down or at least can be free.
- the at least one or the preferred two support pins can thus be freely transversely movable in order to cooperate with the known, corresponding shoes in fulfillment of the support function.
- the support means is preferably movable relative to the hold-down and preferably independently of the hold-down.
- the hold-down device can be movable relative to the support device, preferably independently of the support device, between the closed position and the release position.
- the support device in which the support device protrudes from a closing unit comprising the hold-down device, the support device can be immovably connected to the hold-down device.
- Hold-down device and support device can be formed, for example, in one piece, for example made of plastic by injection molding. They may also be immovably connected to each other by means of a joint connection, for example by means of an adhesive connection or a screw connection. Since the support device should not interfere with the buckled ski when walking, it is advantageous in such embodiments, when the support device and the hold-down can be moved together from an active position they take in the closed state of the heel holder in an inactive position in which the ski boot from the hold-down and the support device is free.
- the support device is movable relative to the hold-down device, so that the support device is movable from an active position to an inactive position when the hold-down device is in the release position.
- the shoe connected to the ski via the toe holder is free of the heel holder in such developments when, on the one hand, the hold-down device occupies the release position and, on the other hand, the support device assumes the inactive position.
- the support means acts as a tread spur for closing the heel holder
- the support means is movable relative to the bearing structure from an upper position to a lower position, preferably pivotable, and coupled to the hold-down such that a Movement of the support means from the upper to the lower position causes a movement of the blank holder from the release position to the closed position.
- the support device can be immovably connected to the hold-down device, for example molded in one piece or firmly joined.
- a support means serving as a tread spur is more preferably movable relative to the hold-down device, as described in the further developments, in that it can be moved into the inactive position when the hold-down device is in the release position.
- it is movably arranged on the closing unit comprising the hold-down device, preferably pivotably.
- the support means can advantageously be moved into a stop contact with the closing unit, so that upon further movement of the support means in the stop contact, the closing unit and thus jointly the hold-down from the release position is moved to the closed position.
- the hold-down device assumes the release position and the support device is in contact with the closing unit, it can fulfill the kick spur function by the skier climbing onto the support device with the shoe and by pushing down, as known from safety bindings, against the spring force of the spring device of the heel holder, preferably the hold-down spring, the support device moves down and in stop contact the hold-down in the closed position. If, during opening of the heel holder, the hold-down device is moved into the release position and the shoe is lifted off the support device, the support device can be moved into the inactive position relative to the hold-down device. In this way, it is possible to change from shutdown to walking without further change in the position of the hold-down device, only by moving the support device into the inactive position.
- An acting as a tread support means advantageously requires no special footwear with a receptacle for the cantilevered support means, since the shoe can rest with its free underside on the support means.
- a support device which is formed for cooperation with one or more receptacles in the rear shoe area, be arranged acting as a tread spur by being coupled to the hold-down in the manner explained.
- the heel holder may advantageously also have a tread pore in addition to the support means in order to close the heel holder by getting into the binding, so that no additional operation of the heel holder is required for the closing.
- the additional tread spur can be fixedly, immovably, connected, for example, joined or formed in one piece with the hold-down device, or coupled accordingly with the hold-down device, as is basically known for pure departure ties.
- Such a tread spur may in particular be part of a closing unit forming the hold-down device.
- the additional tread spur is relieved in the closed state of the heel holder advantageously by the support means of the shoe, preferably free, so that when the ski is buckled the weight of the driver is at least substantially absorbed by the support means.
- the hold-down can be movable relative to the base for a vertical release in a first degree of freedom of movement and for a side release in another, second degree of freedom of movement against a restoring force of the spring device.
- the hold-down is in this respect in the first degree of freedom relative to the bearing structure and in the second degree of freedom together with the bearing structure relative to the base movable.
- the hold-down is supported in preferred embodiments on the bearing structure movable, either directly or via one or more intermediate member (s).
- the hold-down is part of a closing unit.
- the closing unit may be shaped in the manner of a housing and arranged at least partially surrounding the bearing structure.

Description
Die Erfindung betrifft eine Skibindung, die für Tourengeher und Freerider geeignet ist und bei geringem Gewicht im Falle eines Sturzes eine sichere Auslösung gewährleistet.The invention relates to a ski binding that is suitable for touring skiers and freeriders and ensures safe release at low weight in the event of a fall.
Bei Tourengehern und Freeridern besteht der Wunsch nach Skibindungen mit geringem Gewicht. Zum Abfahren wird der Skischuh wie bei anderen Skibindungen auch zwischen einem Zehenhalter und einem Fersenhalter fest eingespannt. Zum Gehen bzw. Steigen wird die Verbindung mit dem Ski im Fersenbereich des Schuhs gelöst, so dass der Schuh bei nach wie vor bestehender Verbindung mit dem Zehenhalter um eine im Bereich des Zehenhalters gelegene Querachse schwenken kann. Bekannt sind Bindungen, beispielsweise aus der
Es ist eine Aufgabe der Erfindung, eine zum Gehen und Steigen mit angeschnalltem Ski und somit für Tourengeher oder Freerider geeignete Skibindung zu schaffen, die trotz geringen Gewichts im Falle eines Sturzes die Auslösung mit höherer Sicherheit gewährleistet.It is an object of the invention to provide a suitable for walking and climbing with strapped ski and thus for tourers or freeriders ski binding, which ensures despite high weight in the event of a fall, the triggering with higher security.
Die Erfindung geht von einer Skibindung aus, die einen Zehenhalter zum Halten eines vorderen Bereichs eines Schuhs und einen Fersenhalter zum Halten eines hinteren Bereichs des Schuhs aufweist. Der Fersenhalter umfasst eine Basis, die mit einem Ski verbunden ist oder durch Montage mit dem Ski verbunden werden kann. Die Basis ist vorteilhafterweise flach, beispielsweise platten- oder schienenförmig. Der Fersenhalter umfasst ferner eine Lagerstruktur, die in eine Vertikalrichtung der Bindung von der Basis aufragt, und eine auskragende Stützeinrichtung, an der der hintere Bereich des Schuhs in Vertikalrichtung abstützbar ist, so dass bei mit dem Ski verbundener Basis zumindest im hinteren Schuhbereich im abgestützten Zustand zwischen Schuh und Ski ein lichter Abstand verbleibt. Befindet sich der Schuh im abgestützten Zustand über der Basis, so schließt dies ein, dass zwischen Schuh und Basis ein lichter Abstand verbleibt. Einem Stopfen durch Schnee wird entgegengewirkt und der Wechsel von Gehen mit Ski auf Abfahren erleichtert. Der lichte Abstand beträgt vorzugsweise wenigstens einen Millimeter. Der Fersenhalter ist zum Schließen und Öffnen der Bindung aus einem Freigabezustand in einen Schließzustand und aus dem Schließzustand wieder in den Freigabezustand überführbar. Der Fersenhalter kann zumindest was den Gebrauch des Ski anbetrifft, fest mit dem Ski verbunden sein, muss also zum Gehen mit angeschnalltem Ski nicht vom Ski gelöst werden, wie dies bei Tourenbindungen mit schwenkbarer Tourenplatte der Fall ist. Eine lösbar und im gelösten Zustand beweglich mit dem Ski verbundene Tourenplatte kann entfallen. Die erfindungsgemäße Skibindung kann daher vorteilhafterweise eine tourengeeignete plattenlose Skibindung sein.The invention is based on a ski binding which has a toe holder for holding a front region of a shoe and a heel holder for holding a rear region of the shoe. The heel holder comprises a base which is connected to a ski or can be connected by mounting with the ski. The base is advantageously flat, such as plate or rail. The heel holder further comprises a bearing structure, which projects in a vertical direction of the binding from the base, and a projecting support means, on which the rear portion of the shoe is supported in the vertical direction, so that when connected to the ski base at least in the rear shoe area in the supported state a clear distance remains between shoe and ski. When the shoe is supported over the base, this includes leaving a clearance between the shoe and the base. A plug through snow is counteracted and facilitates the change from walking to skiing on downhill. The clear distance is preferably at least one millimeter. The heel holder is for closing and opening the binding from a release state into a closed state and from the closed state again in the release state can be transferred. The heel holder can at least as far as the use of the ski, be firmly connected to the ski, so it must not be solved for walking with buckled ski from the ski, as is the case with touring bindings with swivel touring plate. A detachable and in the dissolved state movably connected to the ski tour plate can be omitted. The ski binding according to the invention can therefore advantageously be a tour-suitable, diskless ski binding.
Der Zehenhalter ist so ausgebildet, dass er den Schuh im vorderen Schuhbereich zum Gehen mit angeschnalltem Ski beweglich, vorzugsweise schwenkbar hält, bevorzugt durch Bildung eines Gelenks lagert. Der Zehenhalter kann wie ein Zehenhalter bekannter Bindungen, beispielsweise der Tourenbindung der
Nach der Erfindung weist der Fersenhalter zusätzlich zur Stützeinrichtung einen Niederhalter auf, der relativ zur Lagerstruktur zwischen einer dem Schließzustand des Fersenhalters entsprechenden Schließposition und einer dem Freigabezustand des Fersenhalters entsprechenden Freigabeposition hin und her beweglich ist, vorzugsweise schwenkbeweglich, um den Schuh in der Schließposition auf der Stützeinrichtung ruhend niederzuhalten und in der Freigabeposition freizugeben. Ferner umfasst der Fersenhalter eine Federeinrichtung, die zumindest eine Niederhaltefeder aufweist, gegen deren Rückstellkraft der Niederhalter aus der Schließposition in die Freigabeposition beweglich ist. Der Niederhalter ist vorzugsweise so ausgebildet, dass er in der Schließposition von oben auf eine im hinteren Schuhbereich freie Oberseite des Schuhs, beispielsweise eine Oberseite einer überstehenden Schuhsohle, und dadurch die Unterseite des Schuhs auf die Stützeinrichtung drückt. Die Funktionsweise und auch die Form des erfindungsgemäßen Niederhalters kann zum Niederhalten des Schuhs der Funktionsweise eines Sohlenhalters von tourengeeigneten Sicherheitsbindungen entsprechen, wie sie beispielsweise aus der
Ein Vorteil eines Fersenhalters mit einer Stützeinrichtung und einem Niederhalter ist, dass der Fersenhalter insbesondere bei einer Abfahrt eine gute Kippsteifigkeit aufweist, da der Fersenhalter durch die Stützeinrichtung sich nicht oder im Wesentlichen nicht quer zu einer Skilaufrichtung bewegen kann und zusätzlich gleichzeitig in Richtung auf die Skioberfläche gespannt ist.An advantage of a heel holder with a support device and a hold-down device is that the heel holder has a good tilting rigidity, in particular on a descent, since the heel holder by the support means is not or substantially not transverse to a skiing direction can move and is additionally stretched simultaneously towards the ski surface.
Ein Abstand zwischen der Stützeinrichtung und dem Niederhalter kann zumindest in der Situation, in der die Stützeinrichtung und der Niederhalter den Skischuh in einer Fahrtposition auf dem Ski halten, unveränderlich sein. Der Abstand entspricht einem Abstand zwischen einem Eingriffsbereich für den Niederhalter und einem Eingriffsbereich der Stützeinrichtung an der Skischuhsohle.A distance between the support means and the hold-down may be fixed, at least in the situation where the support means and the hold-down hold the ski boot in a riding position on the ski. The distance corresponds to a distance between an engagement region for the hold-down device and an engagement region of the support device on the ski boot sole.
Damit der Abstand konstant gehalten wird, auch zum Beispiel bei einem Stopfen aus Schnee unter der Skischuhsohle, sind die Stützeinrichtung und der Niederhalter im Wesentlichen nicht elastisch verformbar sondern verbiegungssteif ausgebildet.In order for the distance to be kept constant, for example in the case of a plug of snow under the ski boot sole, the support device and the hold-down device are essentially not elastically deformable, but are designed so that they are resistant to bending.
Eine Schneespannhöhe des Fersenhalters kann zum Beispiel ca. 6 mm betragen. Dabei ist unter der Schneespannhöhe eine Höhe des Schneestopfens zu verstehen, der zum Beispiel zwischen der Basis des Fersenhalters und der Skischuhsohle gebildet ist. Im Regelfall schließt der Fersenhalter respektive der Niederhalter zuverlässig bis zu der genannten Schneespannhöhe von ca. 6 mm. In dieser Position kann auch die Stützeinrichtung bereits eine stützende Verbindung mit dem Skischuh eingehen, sodass der Skischuh sicher in dem Fersenhalter gehalten wird. Verringert sich die Höhe des Schneestopfens, kann die Federeinrichtung des Fersenhalters respektive die Niederhaltefeder den Niederhalter sozusagen "nachdrücken", bis bei einer Höhe des Schneestopfens von 0 mm der Skischuh direkt auf der Basis aufsteht.A snow span height of the heel holder may be, for example, about 6 mm. In this case, the snow span height is to be understood as meaning a height of the snow plug which is formed, for example, between the base of the heel holder and the ski boot sole. As a rule, the heel holder or downholder reliably closes up to the mentioned snow span height of approx. 6 mm. In this position, the support device can already enter into a supporting connection with the ski boot, so that the ski boot is held securely in the heel holder. Decreases the height of the snow plug, the spring means of the heel holder and the hold-down spring, so to speak, "hold down" the hold-down until at a height of the snow plug of 0 mm, the ski boot stands directly on the base.
Der Erfindung gelingt es, den wesentlichen Vorteil plattenloser Tourenbindungen, nämlich deren geringes Gewicht, mit erhöhter Auslösesicherheit und für das Abfahren vorteilhaft steifer Halterung des Schuhs zu vereinen. Die Erfindung trennt die Funktion des Stützens mit lichtem Abstand vom Ski und der Basis, falls diese sich unter der Stützeinrichtung erstreckt, von der Funktion des Niederhaltens durch Bereitstellung einer dem Abstützen dienenden Stützeinrichtung und eines dem Niederhalten dienenden Niederhalters, der dafür sorgt, dass der Schuh bei geschlossener Bindung auf die Stützeinrichtung gepresst wird. Der Schuh wird aufgrund des Zusammenwirkens von Niederhalter und Stützeinrichtung im Schließzustand des Fersenhalters steifer als bei den bekannten plattenlosen Tourenbindungen gehalten. Die Stützeinrichtung und der Niederhalter sind vorzugsweise so ausgebildet, dass der Niederhalter unmittelbar auf den Schuh und diesen unmittelbar auf die Stützeinrichtung presst, vorzugsweise von oben drückt. Die Stützeinrichtung wird von ihrer Doppelfunktion, die sie bei den plattenlosen Tourenbindungen der genannten Art erfüllen muss, entlastet. Vorzugsweise muss sie nur noch ihre eigentliche Funktion, die Stützfünktion, erfüllen. Die erfindungsgemäße Bindung ist auch bequemer handhabbar, da das mühsame Öffnen der Stützeinrichtung beim Wechsel von Abfahren auf Gehen mit angeschnalltem Ski entfällt und stattdessen nur noch ein von der Stützfunktion freier Niederhalter aus der Schließposition in die Freigabeposition bewegt werden muss.The invention makes it possible to combine the significant advantage of diskless touring bindings, namely their low weight, with increased triggering safety and, for the downhill ride, advantageously rigid mounting of the boot. The invention separates the function of supporting lightly spaced from the ski and the base, if it extends under the support means of the function of holding down by providing a supporting support means and a hold down holddown, which ensures that the shoe is pressed on the support means with the binding closed. The shoe is held stiffer than in the known plateless touring bindings due to the interaction of hold-down and support means in the closed state of the heel holder. The support means and the hold-down device are preferably designed so that the hold-down presses directly on the shoe and this directly on the support means, preferably presses from above. The support device is relieved of its double function, which it must meet in the diskless touring bindings of the type mentioned. Preferably, it only has to fulfill its actual function, the support function. The binding according to the invention is also easier to handle, since the tedious opening of the support device when changing from shutdown to walking with buckled ski eliminated and instead only one of the support function free hold down from the closed position must be moved to the release position.
Obgleich die Stützeinrichtung grundsätzlich von der Basis in Form einer den Schuh frei stellenden Stützstruktur nach oben aufragen und in diesem Sinne auskragen kann, beispielsweise stiftförmig, wird Ausführungen der Vorzug gegeben, in denen die Stützeinrichtung oberhalb des Skis oder oberhalb der Basis, falls die Basis sich in Längsrichtung auf den Zehenhalter zu über die Lagerstruktur hinaus erstreckt, und in derartigen Ausführungen mit einem lichten Abstand zur Basis, in Richtung auf den Zehenhalter auskragt.Although the support means may project upwardly from the base in the form of a support structure exposing the shoe, such as a pin, embodiments are preferred in which the support means above the ski or above the base, if the base itself extends longitudinally on the toe holder beyond the bearing structure, and in such embodiments with a clearance to the base, projecting towards the toe holder.
In ersten Ausführungen ragt die Stützeinrichtung von der Lagerstruktur ab. In zweiten Ausführungen kragt die Stützeinrichtung von einer Schließeinheit aus, die den Niederhalter umfasst.In first embodiments, the support device protrudes from the bearing structure. In second embodiments, the support device projects from a closing unit which comprises the hold-down device.
Für das Gehen mit angeschnalltem Ski ist es von Vorteil, wenn die Stützeinrichtung relativ zur Basis zwischen einer Aktivposition und einer Inaktivposition hin und her beweglich ist. Dabei kann der Fersenhalter zum Beispiel an einer Außenseite einen Hebel aufweisen, der mit der Stützeinrichtung verbunden ist und zusammen mit der Stützeinrichtung verschwenkt werden kann. Nimmt die Stützeinrichtung die Aktivposition ein, kann sich der Schuh mit seinem hinteren Bereich auf der Stützeinrichtung abstützen. Nimmt die Stützeinrichtung die Inaktivposition ein, ist der Schuh von der Stützeinrichtung frei und kann beim Gehen bis auf die Oberseite des Ski oder der Basis durchgedrückt werden. Die Beweglichkeit zwischen der Aktivposition und der Inaktivposition kann insbesondere eine Schwenkbeweglichkeit oder eine translatorische Beweglichkeit sein oder solch eine Beweglichkeit umfassen. Die Stützeinrichtung kann zwischen den beiden Positionen gemeinsam mit dem Niederhalter oder der Lagerstruktur hin und her beweglich sein. Das Wort "oder" wird hier wie auch sonst von der Erfindung stets im üblichen logischen Sinne eines "inklusiv oder" verstanden, umfasst also sowohl die Bedeutung von "entweder ... oder" als auch die Bedeutung von "und", soweit sich aus dem jeweils konkreten Zusammenhang nicht ausschließlich nur eine dieser beiden Bedeutungen ergeben kann. Bezogen auf den Niederhalter und die Lagerstruktur bedeutet dies beispielsweise, dass in ersten Varianten die Stützeinrichtung gemeinsam mit dem Niederhalter, aber relativ zur Lagerstruktur, in zweiten Varianten gemeinsam mit der Lagerstruktur, aber relativ zum Niederhalter, und in dritten Varianten gemeinsam sowohl mit dem Niederhalter als auch der Lagerstruktur zwischen der Aktivposition und der Inaktivposition hin und her beweglich sein kann. Die Stützeinrichtung kann auch so angeordnet sein, dass sie in unterschiedliche Inaktivpositionen beweglich ist. Die unterschiedlichen Inaktivpositionen haben jedoch alle die gemeinsame Eigenschaft, dass bei in der jeweiligen Inaktivposition befindlicher Stützeinrichtung der Schuh frei von der Stützeinrichtung bis auf den Ski oder die Basis oder eine gegebenenfalls andere an der Oberseite des Ski befindliche Kontaktstelle bewegt werden kann. Die Stützeinrichtung kann in der Inaktivposition oder den unterschiedlichen Inaktivpositionen zumindest nicht in Bezug auf die Vertikalrichtung eine Stützfunktion für den Schuh ausüben.For walking with strapped ski, it is advantageous if the support means is movable relative to the base between an active position and an inactive position back and forth. In this case, the heel holder, for example, on an outer side having a lever which is connected to the support means and can be pivoted together with the support means. If the support device assumes the active position, the shoe can be supported with its rear region on the support device. If the support device assumes the inactive position, the shoe is free of the support device and can be pushed down to the top of the ski or the base when walking. The mobility between the active position and the inactive position may in particular be a pivoting mobility or a translatory mobility or comprise such a mobility. The support means can be reciprocated between the two positions, together with the hold-down or the bearing structure. Here and elsewhere, the word "or" is always understood by the invention in the usual logical sense of an "inclusive or", thus encompassing both the meaning of "either ... or" and the meaning of "and" as far as from the respective concrete context can not exclusively give only one of these two meanings. Relative to the hold-down and the bearing structure, this means, for example, that in first variants, the support means together with the hold-down, but relative to the bearing structure, in second variants together with the bearing structure, but relative to the hold-down, and in third variants together with both the holddown Also, the bearing structure between the active position and the inactive position can be moved back and forth. The support means may also be arranged to be movable to different inactive positions. However, the different inactive positions all have the common characteristic that, when the support device is in the respective inactive position, the shoe can be moved freely from the support device to the ski or the base or any other contact point located at the top of the ski. In the inactive position or the different inactive positions, the support device can at least not exercise a support function for the shoe with respect to the vertical direction.
In den ersten Ausführungen, in denen die Stützeinrichtung von der Lagerstruktur auskragt, kann die Stützeinrichtung vorteilhafterweise auch unmittelbar an der Lagerstruktur in Vertikalrichtung abgestützt sein. Sie kann mit der Lagerstruktur in einem Stück geformt sein, beispielsweise als ein Spritzgussteil aus Kunststoff. Sie kann stattdessen mit der Lagerstruktur aber auch unbeweglich gefügt sein, beispielsweise mittels Schraubverbindung oder Klebeverbindung oder einer anderen geeigneten Fügeverbindung. In bevorzugten Ausführungen ist die Stützeinrichtung relativ zur Lagerstruktur querbeweglich, d. h. quer zur Längsrichtung und Vertikalrichtung der Bindung, beispielsweise orthogonal zur Längsrichtung und zur Vertikalrichtung. Die Stützeinrichtung kann wie die genannten plattenlosen Tourenbindungen einen von der Lagerstruktur abragenden ersten Stützstift und einen von der Lagerstruktur abragenden zweiten Stützstift umfassen, die mit im hinteren Bereich korrespondierend ausgebildeten Schuhen zusammenwirken können, indem der erste und der zweite Stützstift jeweils in eine korrespondierende Aufnahme im hinteren Bereich solch eines Schuhs hineinragt, wenn sich der Schuh an der Stützeinrichtung abstützt. Wie bei den bekannten Stützeinrichtungen auch kann wenigstens einer der Stützstifte relativ zur Lagerstruktur und dem anderen der Stützstifte in Querrichtung beweglich und dadurch ein in Querrichtung zwischen den Stützstiften gemessener Abstand veränderlich sein. Zweckmäßigerweise sind sowohl der erste als auch der zweite Stützstift relativ zur Lagerstruktur querbeweglich. Anders als bei den bekannten Tourenbindungen muss der jeweilige querbewegliche Stützstift nicht gegen eine rückstellende Federkraft beweglich sein, da die Stützeinrichtung im Schließzustand des Fersenhalters erfindungsgemäß von der Funktion des Niederhaltens frei ist oder zumindest frei sein kann. Der wenigstens eine oder die bevorzugt beiden Stützstifte können somit frei querbeweglich sein, um mit den bekannten, korrespondierenden Schuhen in Erfüllung der Stützfunktion zusammenwirken zu können. Andererseits kann es von Vorteil sein, wenn der bewegliche Stützstift oder die beweglichen Stützstifte gegen eine vergleichsweise geringe Federkraft querbeweglich sind, um den Stiften eine Position vorzugeben und dadurch das Einfädeln in die Aufnahmen des Schuhs beim Einsteigen in die Bindung zu erleichtern.In the first embodiments, in which the support device protrudes from the bearing structure, the support means can advantageously also be supported directly on the bearing structure in the vertical direction. It can be molded in one piece with the bearing structure, for example as an injection-molded part made of plastic. However, it may instead be immovably joined to the bearing structure, for example by means of a screw connection or adhesive connection or another suitable joint connection. In preferred embodiments, the support means is transversely movable relative to the bearing structure, ie transversely to the longitudinal direction and vertical direction of the bond, for example orthogonal to the longitudinal direction and the vertical direction. The support means may include as said plateless touring bindings projecting from the bearing structure first support pin and projecting from the bearing structure second support pin which can cooperate with correspondingly formed in the rear shoes, by the first and the second support pin in each case in a corresponding receptacle in the rear Protected portion of such a shoe when the shoe is supported on the support means. As with the known support means, at least one of the support pins may be movable transversely relative to the bearing structure and the other of the support pins, thereby varying a distance measured transversely between the support pins. Conveniently, both the first and the second support pin are transversely movable relative to the bearing structure. Unlike the well-known touring bindings the respective transversely movable support pin must not be movable against a restoring spring force, since the support device according to the invention in the closed state of the heel holder is free of the function of holding down or at least can be free. The at least one or the preferred two support pins can thus be freely transversely movable in order to cooperate with the known, corresponding shoes in fulfillment of the support function. On the other hand, it may be advantageous if the movable support pin or the movable support pins are transversely movable against a comparatively small spring force to give the pins a position and thereby facilitate the threading into the shots of the shoe when entering the binding.
In den ersten Ausführungen ist die Stützeinrichtung vorzugsweise relativ zum Niederhalter und vorzugsweise unabhängig vom Niederhalter beweglich. In den ersten Ausführungen kann insbesondere der Niederhalter relativ zur Stützeinrichtung, vorzugsweise unabhängig von der Stützeinrichtung, zwischen der Schließposition und der Freigabeposition hin und her beweglich sein.In the first embodiments, the support means is preferably movable relative to the hold-down and preferably independently of the hold-down. In the first embodiments, in particular the hold-down device can be movable relative to the support device, preferably independently of the support device, between the closed position and the release position.
In den zweiten Ausführungen, in denen die Stützeinrichtung von einer den Niederhalter umfassenden Schließeinheit auskragt, kann die Stützeinrichtung mit dem Niederhalter unbeweglich verbunden sein. Niederhalter und Stützeinrichtung können beispielsweise in einem Stück geformt sein, etwa aus Kunststoff im Spritzguss. Sie können miteinander auch mittels einer Fügeverbindung unbeweglich verbunden sein, beispielsweise mittels einer Klebeverbindung oder einer Schraubverbindung. Da die Stützeinrichtung beim Gehen mit angeschnalltem Ski nicht stören sollte, ist es in derartigen Ausführungen von Vorteil, wenn die Stützeinrichtung und der Niederhalter gemeinsam aus einer Aktivposition, die sie im Schließzustand des Fersenhalters einnehmen, in eine Inaktivposition bewegt werden können, in denen der Skischuh von dem Niederhalter und der Stützeinrichtung frei ist.In the second embodiments, in which the support device protrudes from a closing unit comprising the hold-down device, the support device can be immovably connected to the hold-down device. Hold-down device and support device can be formed, for example, in one piece, for example made of plastic by injection molding. They may also be immovably connected to each other by means of a joint connection, for example by means of an adhesive connection or a screw connection. Since the support device should not interfere with the buckled ski when walking, it is advantageous in such embodiments, when the support device and the hold-down can be moved together from an active position they take in the closed state of the heel holder in an inactive position in which the ski boot from the hold-down and the support device is free.
In Weiterbildungen der zweiten Ausführungen ist die Stützeinrichtung relativ zum Niederhalter hin und her beweglich, so dass die Stützeinrichtung bei in der Freigabeposition befindlichem Niederhalter aus einer Aktivposition in eine Inaktivposition beweglich ist. Der über den Zehenhalter mit dem Ski verbundene Schuh ist in derartigen Weiterbildungen vom Fersenhalter frei, wenn zum einen der Niederhalter die Freigabeposition und zum anderen die Stützeinrichtung die Inaktivposition einnehmen.In further developments of the second embodiments, the support device is movable relative to the hold-down device, so that the support device is movable from an active position to an inactive position when the hold-down device is in the release position. The shoe connected to the ski via the toe holder is free of the heel holder in such developments when, on the one hand, the hold-down device occupies the release position and, on the other hand, the support device assumes the inactive position.
In Ausführungen, in denen die Stützeinrichtung als Trittsporn zum Schließen des Fersenhalters wirkt, wie vorzugsweise in den zweiten Ausführungen, ist die Stützeinrichtung relativ zur Lagerstruktur aus einer oberen Position in eine untere Position beweglich, vorzugsweise schwenkbeweglich, und mit dem Niederhalter so gekoppelt, dass eine Bewegung der Stützeinrichtung aus der oberen in die untere Position eine Bewegung des Niederhalters aus der Freigabeposition in die Schließposition bewirkt. Die Stützeinrichtung kann in Ausführungen, in denen sie als Trittsporn wirkt, mit dem Niederhalter unbeweglich verbunden, beispielsweise in einem Stück geformt oder fest gefügt sein. Bevorzugter ist eine als Trittsporn dienende Stützeinrichtung jedoch, wie zu den Weiterbildungen geschildert, relativ zum Niederhalter derart beweglich, dass sie bei in der Freigabeposition befindlichem Niederhalter in die Inaktivposition bewegt werden kann. Vorzugsweise ist sie beweglich an der den Niederhalter umfassenden Schließeinheit angeordnet, vorzugsweise schwenkbeweglich. In derartigen Ausführungen kann die Stützeinrichtung vorteilhafterweise in einen Anschlagkontakt mit der Schließeinheit bewegt werden, so dass bei weiterer Bewegung der Stützeinrichtung im Anschlagkontakt die Schließeinheit und damit gemeinsam der Niederhalter aus der Freigabeposition in die Schließposition bewegt wird. Nimmt der Niederhalter die Freigabeposition ein und befindet sich die Stützeinrichtung in dem Anschlagkontakt mit der Schließeinheit, kann sie die Trittspornfunktion erfüllen, indem der Skifahrer mit dem Schuh auf die Stützeinrichtung steigt und durch Druck nach unten, wie von Sicherheitsbindungen bekannt, gegen die Federkraft der Federeinrichtung des Fersenhalters, vorzugsweise der Niederhaltefeder, die Stützeinrichtung nach unten und im Anschlagkontakt den Niederhalter in die Schließposition bewegt. Wenn beim Öffnen des Fersenhalters der Niederhalter in die Freigabeposition bewegt und der Schuh von der Stützeinrichtung abgehoben wird, kann die Stützeinrichtung relativ zum Niederhalter in die Inaktivposition bewegt werden. Auf diese Weise kann ohne weitere Positionsveränderung des Niederhalters, nur durch Bewegung der Stützeinrichtung in die Inaktivposition, von Abfahren auf Gehen gewechselt werden. Eine als Trittsporn wirkende Stützeinrichtung bedarf vorteilhafterweise keines speziellen Schuhwerks mit einer Aufnahme für die auskragende Stützeinrichtung, da der Schuh mit seiner freien Unterseite auf der Stützeinrichtung aufliegen kann. Andererseits kann aber auch eine Stützeinrichtung, die für das Zusammenwirken mit einer oder mehrerer Aufnahmen im hinteren Schuhbereich gebildet ist, als Trittsporn wirkend angeordnet sein, indem sie mit dem Niederhalter in der erläuterten Weise gekoppelt ist.In embodiments in which the support means acts as a tread spur for closing the heel holder, as preferably in the second embodiments, the support means is movable relative to the bearing structure from an upper position to a lower position, preferably pivotable, and coupled to the hold-down such that a Movement of the support means from the upper to the lower position causes a movement of the blank holder from the release position to the closed position. In embodiments in which it acts as a tread spur, the support device can be immovably connected to the hold-down device, for example molded in one piece or firmly joined. However, a support means serving as a tread spur is more preferably movable relative to the hold-down device, as described in the further developments, in that it can be moved into the inactive position when the hold-down device is in the release position. Preferably, it is movably arranged on the closing unit comprising the hold-down device, preferably pivotably. In such embodiments, the support means can advantageously be moved into a stop contact with the closing unit, so that upon further movement of the support means in the stop contact, the closing unit and thus jointly the hold-down from the release position is moved to the closed position. If the hold-down device assumes the release position and the support device is in contact with the closing unit, it can fulfill the kick spur function by the skier climbing onto the support device with the shoe and by pushing down, as known from safety bindings, against the spring force of the spring device of the heel holder, preferably the hold-down spring, the support device moves down and in stop contact the hold-down in the closed position. If, during opening of the heel holder, the hold-down device is moved into the release position and the shoe is lifted off the support device, the support device can be moved into the inactive position relative to the hold-down device. In this way, it is possible to change from shutdown to walking without further change in the position of the hold-down device, only by moving the support device into the inactive position. An acting as a tread support means advantageously requires no special footwear with a receptacle for the cantilevered support means, since the shoe can rest with its free underside on the support means. On the other hand, however, a support device, which is formed for cooperation with one or more receptacles in the rear shoe area, be arranged acting as a tread spur by being coupled to the hold-down in the manner explained.
Der Fersenhalter kann einen Trittsporn vorteilhafterweise auch zusätzlich zur Stützeinrichtung aufweisen, um den Fersenhalter durch Einsteigen in die Bindung schließen zu können, so dass für das Schließen keine zusätzliche Betätigung des Fersenhalters erforderlich ist. Der zusätzliche Trittsporn kann mit dem Niederhalter fest, unbeweglich, verbunden, beispielsweise gefügt oder in einem Stück geformt, oder entsprechend mit dem Niederhalter gekoppelt sein, wie es für reine Abfahrbindungen grundsätzlich bekannt ist. Solch ein Trittsporn kann insbesondere Bestandteil einer den Niederhalter bildenden Schließeinheit sein. Der zusätzliche Trittsporn wird im Schließzustand des Fersenhalters vorteilhafterweise durch die Stützeinrichtung vom Schuh entlastet, vorzugsweise freigestellt, so dass bei angeschnalltem Ski das Gewicht des Fahrers zumindest im Wesentlichen von der Stützeinrichtung aufgenommen wird.The heel holder may advantageously also have a tread pore in addition to the support means in order to close the heel holder by getting into the binding, so that no additional operation of the heel holder is required for the closing. The additional tread spur can be fixedly, immovably, connected, for example, joined or formed in one piece with the hold-down device, or coupled accordingly with the hold-down device, as is basically known for pure departure ties. Such a tread spur may in particular be part of a closing unit forming the hold-down device. The additional tread spur is relieved in the closed state of the heel holder advantageously by the support means of the shoe, preferably free, so that when the ski is buckled the weight of the driver is at least substantially absorbed by the support means.
Um den Charakter der Skibindung als Sicherheitsbindung noch zu verstärken, kann der Niederhalter relativ zur Basis für eine Vertikalauslösung in einem ersten Freiheitsgrad der Bewegung und für eine Seitenauslösung in einem anderen, zweiten Freiheitsgrad der Bewegung jeweils gegen eine Rückstellkraft der Federeinrichtung beweglich sein. In bevorzugten Ausführungen ist der Niederhalter unter diesem Gesichtspunkt im ersten Freiheitsgrad relativ zur Lagerstruktur und im zweiten Freiheitsgrad gemeinsam mit der Lagerstruktur relativ zur Basis beweglich. Grundsätzlich ist aber auch denkbar, den Niederhalter relativ zur Lagerstruktur im ersten und auch im zweiten Freiheitsgrad beweglich anzuordnen.In order to reinforce the character of the ski binding as a safety binding, the hold-down can be movable relative to the base for a vertical release in a first degree of freedom of movement and for a side release in another, second degree of freedom of movement against a restoring force of the spring device. In preferred embodiments, the hold-down is in this respect in the first degree of freedom relative to the bearing structure and in the second degree of freedom together with the bearing structure relative to the base movable. In principle, however, it is also conceivable to arrange the hold-down device relative to the bearing structure in the first and also in the second degree of freedom.
Der Niederhalter ist in bevorzugten Ausführungen an der Lagerstruktur beweglich abgestützt, entweder direkt oder über ein oder mehrere Zwischenglied(er). In zweckmäßigen Ausführungen ist der Niederhalter Bestandteil einer Schließeinheit. Die Schließeinheit kann in der Art eines Gehäuses geformt und die Lagerstruktur zumindest teilweise umgebend angeordnet sein.The hold-down is supported in preferred embodiments on the bearing structure movable, either directly or via one or more intermediate member (s). In appropriate embodiments, the hold-down is part of a closing unit. The closing unit may be shaped in the manner of a housing and arranged at least partially surrounding the bearing structure.

Der Fersenhalter 10 umfasst eine Basis 2 für eine feste Verbindung mit dem Ski 1. Die Basis 2 umfasst wie bevorzugt, aber nur beispielhaft ein fest mit dem Ski 1 verbundenes erstes Basisteil und ein zweites Basisteil, das mit dem ersten Basisteil in Längsrichtung X beweglich, ansonsten jedoch unbeweglich verbunden ist. Von der Basis 2, im Beispiel vom zweiten Basisteil, ragt eine Lagerstruktur 3 auf, von der eine Stützeinrichtung 4 in Form eines linken Stützstifts 4 und eines rechten Stützstifts 4 in Längsrichtung X, d. h. in Richtung auf den Zehenhalter, auskragt. Die Stützeinrichtung 4 dient der Abstützung des Skischuhs in Vertikalrichtung Z. Im abgestützten Zustand greift die Stützeinrichtung 4 in korrespondierende Ausnehmungen, die der Schuh im hinteren Schuhbereich aufweist, wobei die Stützeinrichtung 4 so angeordnet ist, dass der sich auf der Stützeinrichtung 4 in Richtung auf den Ski 1 abstützende Schuh an seiner Unterseite einen lichten Abstand von der Oberseite des Ski aufweist. Sollte sich die Basis in Längsrichtung X bis unter die Stützeinrichtung 4 erstrecken, weist die Unterseite des Schuhs im abgestützten Zustand einen lichten Abstand von der Oberseite der Basis 2 auf. Durch die Abstützung des Schuhs auf der Stützeinrichtung 4 wird daher verhindert, dass bei einem Gehen mit dem Ski 1 im Bereich des Fersenhalters 10 angesammelter Schnee beim Wiedereinsteigen in die Bindung ein Schließen des Fersenhalters 10 behindert.The
Anders als bei bekannten plattenlosen Tourenbindungen muss die Stützeinrichtung 4 den Schuh jedoch zum Abfahren nicht relativ zum Ski 1 fest niederhalten. Zur Erfüllung dieser Funktion umfasst der Fersenhalter 10 zusätzlich zur Stützeinrichtung 4 einen Niederhalter 6, der im Schließzustand des Fersenhalters 10 den Schuh auf die Stützeinrichtung 4 drückt. Der Schuh wird im Schließzustand des Fersenhalters 10 zwischen der Stützeinrichtung 4 und dem Niederhalter 6 vorteilhafterweise geklemmt. Der Niederhalter 6 ist so ausgebildet, dass er eine überstehende Sohle des Schuhs im hinteren Schuhbereich links und rechts übergreift und den Schuh dadurch wie grundsätzlich von reinen Abfahrbindungen bekannt niederhält, allerdings wegen der Stützeinrichtung 4 in besagtem lichten Abstand zum Ski.Unlike known plateless touring bindings, however, the support means 4 does not have to firmly hold the shoe down relative to the
Der Niederhalter 6 ist Bestandteil einer Schließeinheit 5, zu der ferner auch ein Trittsporn 7 gehört. Niederhalter 6 und Trittsporn 7 sind relativ zueinander unbeweglich. Im Ausführungsbeispiel ist die Schließeinheit 5 mit Niederhalter 6 und Trittsporn 7 in einem Stück geformt. Der Niederhalter 6 und der Trittsporn 7 sowie optional weitere Teile der Schließeinheit 5 können aber auch separat voneinander geformt und fest miteinander gefügt sein, um die Schließeinheit 5 zu bilden. Grundsätzlich können der Niederhalter 6 und der Trittsporn 7 auch relativ zueinander beweglich, aber in derartigen Ausführungen miteinander so gekoppelt sein, dass beim Einsteigen in die Bindung durch Druck auf den Trittsporn 7 der Niederhalter 6 aus der in
Die Schließeinheit 5 ist gehäuseartig geformt. Die Lagerstruktur 3 ragt von unten, d. h. von der Basis 2 aus in die Schließeinheit 5.The
Der Fersenhalter 10 umfasst ferner einen Betätigungshebel 19, durch dessen Betätigung der Niederhalter 6, im Ausführungsbeispiel die gesamte Schließeinheit 5, aus der Schließposition in die Freigabeposition bewegt werden kann, um den Schuh zum Gehen oder Steigen oder zum Abschnallen des Ski 1 im Fersenbereich freizugeben. Der Betätigungshebel 19 ist mit der Schließeinheit 5 um eine zur Querrichtung Y parallele Schwenkachse schwenkbeweglich. Die schwenkbewegliche Verbindung wird mittels eines Gelenkelements 8 geschaffen, das als relativ zur Schließeinheit 5 unbewegliches Achselement gebildet ist. Das Gelenkelement 8 kann mit der Schließeinheit 5 in einem Stück geformt oder mit dieser fest gefügt sein. Der Betätigungshebel 10 ist relativ zur Schließeinheit 5 um dieses Gelenkelement 8 schwenkbeweglich. Das Gelenkelement 8 kann alternativ aber auch fest mit dem Betätigungshebel 19 verbunden oder an diesem in einem Stück geformt sein und mit der Schließeinheit 5 drehbeweglich verbunden sein. In noch einer Alternative kann das Gelenkelement 8 relativ jeweils zu der Schließeinheit 5 und dem Betätigungshebel 19 um die Schwenkachse des Betätigungshebels 19 drehbar sein.The
Der Betätigungshebel 19 ist zum Öffnen der Bindung mit der Basis 2 in einem Kurvengelenk gekoppelt. Die Basis 2 bildet eine Führungskurve 2a des Kurvengelenks, wie bevorzugt, aber nur beispielhaft an einer dem Ski 1 abgewandten Oberseite, und der Betätigungshebel 19 weist an einer der Führungskurve 2a zugewandten Seite Eingriffselemente 19a und 19b auf, die im Eingriff mit der Führungskurve 2a als Eingriffsnocken des Betätigungshebels 19 wirken. Die Führungskurve 2a und die Eingriffselemente 19a und 19b sind so geformt und relativ zur Schwenkachse des Betätigungshebels 19 angeordnet, dass bei einem Niederdrücken des Betätigungshebels 19 in einer ersten Phase des Niederdrückens das Eingriffselement 19a im Eingriff mit der Führungskurve 2 ist und die Schwenkachse bei 8 und damit gemeinsam die Schließeinheit 5 mit Niederhalter 6 durch das Niederdrücken über einen zwischen dem Eingriffselement 19a und der Schwenkachse vorhandenen Hebel vom Ski 1 weg aufwärts bewegt wird. Während dieser Aufwärtsbewegung gleitet das Eingriffselement 19a über die Führungskurve 2a. Beim weiteren Niederdrücken gelangt das Eingriffselement 19b in den Eingriff mit der Führungskurve 2a. Im Eingriff der Führungskurve 2a und des Eingriffselements 19b wird beim weiteren Niederdrücken des Betätigungshebels 19 die Schließeinheit 5 mit dem Niederhalter 6 vom Schuh weg nach hinten gekippt und der Schuh im hinteren Schuhbereich dadurch freigegeben. Die gleiche Bewegung führt die Schließeinheit 5 mit dem Niederhalter 6 auch dann aus, wenn beim Abfahren entsprechend hohe Vertikalkräfte auf den Schuh wirken, wie sie insbesondere im Falle eines Sturzes auftreten können. Der Fersenhalter 10 löst in solch einem Fall wie grundsätzlich von reinen Abfahrbindungen bekannt aus. Er bietet somit zum einen die von reinen Abfahrbindungen bekannte Stabilität und Steifigkeit im Schließzustand, ferner die Auslösesicherheit derartiger Bindungen und auch deren bequeme und sichere Betätigung zum Öffnen.The operating

Der Niederhalter 6 wird mit Federkraft, die eine Niederhaltefeder 9 einer Federeinrichtung erzeugt, in der Schließposition gehalten und kann nur gegen diese Federkraft in die Freigabeposition bewegt werden. Die Federeinrichtung umfasst ferner eine Spanner, der in Richtung der Federkraft und gegen die Federkraft hin und her relativ zur Lagerstruktur 3 beweglich ist.The hold-down device 6 is held in the closed position by spring force, which generates a hold-down
Der Spanner umfasst Spannelemente 13 und 14 und ein Verbindungselement 12. Die Niederhaltefeder 9 stützt sich mit einem Federende am Spannelement 13 und mit ihrem anderen Federende an der Lagerstruktur 3 ab. Das andere Spannelement 14 befindet sich vom Spannelement 13 aus gesehen in Richtung der Federkraft hinter dem die Niederhaltefeder 9 abstützenden Bereich der Lagerstruktur 3. Das Verbindungselement 12 verbindet die Spannelemente 13 und 14 in Richtung der Federkraft miteinander. Das Verbindungselement 12 ist mit dem Spannelement 13 gefügt, im Beispiel mittels Schraubverbindung, und bildet für das Spannelement 14 einen Anschlag, gegen den das Spannelement 14 aufgrund der Federkraft gedrückt wird. Die feste Fügeverbindung mit dem Spannelement 13 könnte durch einen in die Gegenrichtung wirkenden Anschlag ersetzt werden, ebenso könnte anstelle der losen Anschlagverbindung auch das Spannelement 14 mit dem Verbindungselement 12 fest gefügt sein, der Spanner 12-14 muss nur die Federkraft der Niederhaltefeder 9 aufnehmen können, so dass diese zwischen den Spannelementen 13 und 14 gespannt werden kann.The tensioner comprises tensioning
Die Lagerstruktur 3 ragt wie bereits erwähnt von der Basis 2 auf und in die Schließeinheit 5 hinein. Die Niederhaltefeder 9 ist in der hohlen Lagerstruktur 3 angeordnet. Das Verbindungselement 12 ragt durch einen Federstützbereich der Lagerstruktur 3, an dem die Niederhaltefeder 9 abgestützt ist, und ragt weiter nach auch durch die Schließeinheit 5. Das Spannelement 14 liegt auf einer von der Lagerstruktur 3 abgewandten Seite der Schließeinheit 5 auf. Zwischen dem Spannelement 14 und dem vom Verbindungselement 12 durchragten Bereich der Lagerstruktur 3 verbleibt ein Spalt, in dem sich ein oberer Bereich der Schließeinheit 5 erstreckt. Die Schließeinheit 5 ist in diesem Bereich, den das Verbindungselement 12 ebenfalls durchragt, mit einer sich in Richtung auf den Niederhalter 6 erstreckenden Ausnehmung versehen, so dass die für die Funktion des Niederhalters 6 erforderliche Beweglichkeit erhalten wird.As already mentioned, the bearing structure 3 protrudes from the

Um beim Gehen mit dem Ski 1 den Schuh über die Stützeinrichtung 4, im ersten Ausführungsbeispiel auch über den Trittsporn 7 hinaus weiter in Richtung auf den Ski 1 bewegen zu können, können die Stützeinrichtung 4 und die Schließeinheit 5 aus dem Interaktionsbereich mit dem Schuh bewegt werden. Zu diesem Zweck ist die Lagerstruktur 3 relativ zur Basis 2 aus der in den
Um die Stützeinrichtung 4 und die Schließeinheit 5 in die Inaktivposition bewegen zu können, ist die Lagerstruktur 3 mit der Basis 2 um eine zur Hochachse Z zumindest im Wesentlichen parallele Achse drehbeweglich verbunden. Die Aktivposition und die Inaktivposition sind im Rahmen der Drehbeweglichkeit vorgegebene Rastpositionen. Der hierbei zwischen der Lagerstruktur 3 und der Basis 2 wirksame Rastmechanismus umfasst, wie in den

Der Betätigungshebel 19 erfüllt eine Doppelfunktion. Zum einen dient er wie beschrieben dem Öffnen des Fersenhalters 10, nämlich dazu, den Niederhalter 6 aus der Schließposition in die Freigabeposition zu bewegen. Zum anderen dient der Betätigungshebel 19 auch als Steighilfe beim Gehen mit dem Ski. Hierfür ist er auch in der Inaktivposition der Lagerstruktur 3 im Rahmen seiner schwenkbeweglichen Lagerung mittels des Gelenkelements 8 in unterschiedliche Positionen schwenkbar. In einer ersten dieser Schwenkpositionen, die der Betätigungshebel 19 in
Zur Erfüllung der Funktion als Steighilfe sind im Bereich des freien Endes in unterschiedliche Richtungen abragende Steighilfeelemente 19c und 19d geformt. Die Steighilfeelemente 19c und 19d ragen am freien Ende des Betätigungshebels 19 voneinander weg, beispielhaft V-förmig. Der Betätigungshebel 19 kann aus seiner in

Die Schließeinheit 25 ist als ein zweiarmiger Hebel gebildet, der um eine mittels eines Gelenkelements 28 gebildete Dreh- bzw. Schwenkachse schwenkbar ist. Einer der beiden Hebelarme der Schließeinheit 25 bildet den Niederhalter 26, und der andere Hebelarm bildet den Betätigungshebel 27.

Die Stützeinrichtung 44 ist im Unterschied zu den anderen Ausführungsbeispielen an der Schließeinheit 45 zwischen einer Aktiv- und einer Inaktivposition hin und her beweglich gelagert. Im Ausführungsbeispiel ist sie wie bevorzugt schwenkbeweglich gelagert. Dazu weist der 40 Fersenhalter einen Hebel 47 auf, der mit der in der
Die Stützeinrichtung 44 bildet auch einen Trittsporn des Fersenhalters 40. Zur Erfüllung der Stütz- und auch der Trittspornfunktion ist sie relativ zur Schließeinheit 45 aus der Inaktivposition bis gegen einen Anschlag der Schließeinheit 45 in die Aktivposition beweglich. Nimmt der Niederhalter 46 die Freigabeposition ein, kann der Skifahrer zum Schließen der Bindung auf die in der Aktivposition befindliche Stützeinrichtung 44 steigen und durch Druck nach unten, in Richtung auf den Ski, über die Stützeinrichtung 44 auf die Schließeinheit 45 wirken und diese und damit gemeinsam den Niederhalter 46 in die Schließposition bewegen.The support means 44 also forms a tread spur of the
Die Niederhaltefeder 49 ist in der Lagerstruktur 43 angeordnet. Die Federeinrichtung weist über die Niederhaltefeder 49 hinaus eine weitere Feder 50 auf, gegen deren rückstellende Federkraft der Fersenhalter 40 bei entsprechend großer, in Querrichtung Y wirkender Seitenkraft auslöst. Der Fersenhalter 40 ermöglicht somit gegen die rückstellende Kraft der Niederhaltefeder 49 eine Vertikalauslösung und gegen die rückstellende Kraft der Feder 50 eine Seitenauslösung.The hold-
