Description

Die vorliegende Erfindung betrifft eine Tourenskibindung, umfassend eine Lageranordnung, welche dafür eingerichtet ist, einen Skischuh um eine quer zu einer Skilängsachse verlaufende Querachse verschwenkbar zu halten, so dass der Skischuh bewegbar ist zwischen einer ersten Schwenkstellung, in der ein Fersenabschnitt des Skischuhs an den Ski angenähert ist, und einer zweiten Schwenkstellung, in der der Fersenabschnitt des Skischuhs von dem Ski entfernt ist.The present invention relates to a touring ski binding, comprising a bearing arrangement, which is adapted to pivotally hold a ski boot about a transverse axis transverse to a ski longitudinal axis, so that the ski boot is movable between a first pivot position, in which a heel portion of the ski boot to the ski and a second pivotal position in which the heel portion of the ski boot is removed from the ski.

Mit einer derartigen Tourenskibindung kann in bekannter Weise in einem Aufstiegsmodus der Bindung ein Skischuh schwenkbar an einem Tourenski gehalten werden, so dass der Skischuh beim Gehen die für jeden Schritt notwendige Bewegungsfreiheit hat. In der ersten Schwenkstellung kann der Fersenabschnitt des Skischuhs direkt auf der Oberfläche des Skis aufsetzen oder kann an einem als Steighilfe dienenden Abschnitt eines hinteren Teiles der Tourenskibindung, insbesondere eines Fersenautomatens, in einer bestimmten Höhe über der Skioberfläche abgestützt sein, so dass der Skischuh in der ersten Schwenkstellung in einem Winkel zur Ebene des Skis angeordnet ist. In der zweiten Schwenkstelung ist der Skischuh nach vorne verschwenkt. Vorteilhaft erlaubt eine Tourenskibindung, dass der Skischuh in der zweiten Schwenkstellung in einem Winkel von bis zu ungefähr 90° in Bezug auf die Skiebene nach vorne verschwenkt ist, da dann eine überhöhte Betastung der Kniegelenke des Benutzers bei einem Sturz nach vorn verhindert werden kann. Solche Tourenskibindungen erfüllen demnach besonders hohe Sicherheitsanforderungen.With such a touring ski binding, a ski boot can be pivotally held on a touring ski in a known manner in a climbing mode of the binding, so that the ski boot has the necessary freedom of movement for each step while walking. In the first pivot position, the heel portion of the ski boot can sit directly on the surface of the ski or can be supported at a serving as a climbing portion of a rear portion of the touring ski binding, in particular a heel counter, at a certain height above the ski surface, so that the ski boot in the first pivot position is arranged at an angle to the plane of the ski. In the second pivoting the ski boot is pivoted forward. Advantageously, a touring ski binding allows the ski boot to be pivoted forward in the second pivotal position at an angle of up to about 90 ° with respect to the skiebene, since then excessive tilting of the user's knee joints in a forward fall can be prevented. Such touring ski bindings therefore meet particularly high safety requirements.

Ferner sind herkömmliche Tourenskibindungen in einen Abfahrtmodus verstellbar, in welchem der Fersenautomat den Fersenabschnitt des Skischuhs am Ski oder dicht oberhalb des Skis festhält.Further, conventional touring ski bindings are adjustable in a downhill mode in which the heel strap holds the heel portion of the ski boot to the ski or just above the ski.

Herkömmliche Tourenskibindungen weisen in der Regel einen Auslösemechanismus auf, welcher bei Einwirkung einer eine vorbestimmte Auslösekraft überschreitenden Kraft auslöst, um den Skischuh von der Lageranordnung freizugeben, so dass sich die Skier im Fall eines Sturzes von den Skischuhen lösen. Dabei verfügen zumeist sowohl der Vorderbacken als auch der Fersenautomat jeweils über einen separaten Auslösemechanismus. Die vorbestimmte Auslösekraft (gemessen als Auslösedrehmoment bei Drehung des Schuhs um eine orthogonal zur Skiebene verlaufende Achse) ist für eine Tourenskibindung entweder fest vorgegeben oder kann durch einen geeigneten Verstellmechanismus in einem Bereich von z.B. ungefähr 30 Nm (Z3) bis maximal ungefähr 100 Nm (Z10) manuell eingestellt werden.Conventional touring ski bindings typically include a triggering mechanism which, upon application of a force exceeding a predetermined release force, releases the ski boot from the bearing assembly so that the skis release from the ski boots in the event of a fall. In most cases, both the toe piece and the heel unit each have a separate release mechanism. The predetermined release force (measured as the triggering torque when the shoe is rotated about an axis orthogonal to the plane of the ski) is either fixed for touring ski binding or may be adjusted by a suitable adjustment mechanism in a range of e.g. about 30 Nm (Z3) to a maximum of about 100 Nm (Z10) can be adjusted manually.

Für sportlich ambitionierte Skitourengeher oder Wettkämpfer, die an einem Skitourenrennen teilnehmen, ist ein Auslösen der Tourenskibindung generell unerwünscht. Während des Aufstiegs, im Tourenskimodus, in welchem ein Fersenautomat die Ferse des Skischuhs freigibt, so dass der Skischuh am Vorderbacken der Tourenskibindung verschwenkbar ist, ist häufig eine Skibremse des Skis deaktiviert, so dass beim Verlust des Skis die Gefahr besteht, dass der Ski am Hang davon rutscht. Zudem bedeutet ein unbeabsichtigtes Auslösen der Tourenskibindung beim Aufstieg sowie bei der Abfahrt unnötigen Zeitverlust. Es ist daher bekannt, die Tourenskibindung mit einem Verriegelungsmechanismus auszustatten, mit welchem die Lageranordnung so verriegelbar ist, dass ein Verschwenken des Skischuhs möglich ist, ein Lösen des Skischuhs von der Lageranordnung (d.h. ein Auslösen der Tourenskibindung) jedoch auch bei Einwirkung einer eine Sturzauslösekraft überschreitenden Kraft verhindert ist. Bei aktiviertem Verriegelungsmechanismus kann der Skischuh quasi nicht mehr beschädigungsfrei von der Tourenskibindung getrennt werden.For athletic ambitious ski tourers or competitors who participate in a ski touring race, triggering the touring ski binding is generally undesirable. During the ascent, in touring ski mode, in which an heel machine releases the heel of the ski boot, so that the ski boot is pivotable on the toe of the touring ski binding, a ski's ski brake is often deactivated so that if the ski is lost there is a risk that the ski will collide Slope of it slips. In addition, an unintentional triggering of the touring ski binding during ascent as well as on departure means unnecessary loss of time. It is therefore known to equip the touring ski binding with a locking mechanism, with which the bearing assembly is lockable so that a pivoting of the ski boot is possible, a release of the ski boot from the bearing assembly (ie triggering the touring ski binding) but also under the action of a fall triggering force bordering Power is prevented. When the locking mechanism is activated, the ski boot can virtually no longer be separated from the touring ski binding without being damaged.

Der herkömmliche Verriegelungsmechanismus erfordert eine zusätzliche Betätigungsbewegung zur Herstellung des Verriegelungszustands. Einige . Tourenskibindungen können allein durch vom Skischuh ausgeübte Druckkraft von der Öffnungsstellung automatisch in die Schließstellung schalten, so dass anschließend allein für die Betätigung des Verriegelungsmechanismus eine Handbedienung durch den Benutzer notwendig ist. Zudem erfordert ein zuverlässiges und gegen unbeabsichtigtes Auslösen gesichertes Verriegeln des Verriegelungsmechanismus häufig einen relativ hohen Kraftaufwand.The conventional locking mechanism requires additional actuating movement to establish the locking condition. Some . Touring ski bindings can automatically switch from the open position to the closed position solely by the pressure exerted by the ski boot, so that subsequently a manual operation by the user is necessary solely for the actuation of the locking mechanism. In addition, a reliable and secured against unintentional release locking the locking mechanism often requires a relatively high force.

Außerdem weist diese Tourenskibindung eine schwenkbare Haube auf, die durch einen Hebel betätigt werden kann.document WO 2009/121187 A1 discloses a touring ski binding with a bearing assembly and a locking mechanism incorporating all features of the preamble of claim 1. In addition, this touring ski binding on a hinged hood, which can be actuated by a lever.

Zur weiteren Illustration des Stands der Technik wird auf die WO 2007/010392 A2 hingewiesen, welche ebenfalls eine Tourenskibindung mit einer Lageranordnung zur schwenkbaren Lagerung eines Skischuhs an gegenüberliegenden Lagerzapfen offenbart.To further illustrate the state of the art, reference is made to FIGS WO 2007/010392 A2 noted, which also discloses a touring ski binding with a bearing assembly for pivotally mounting a ski boot on opposite journals.

Ferner ist aus der nachveröffentlichten Druckschrift EP 2 308 568 A1 eine Tourenskibindung mit einem Verriegelungsmechanismus bekannt, der einen zwischen einer Verriegelungsstellungs und einer Entriegelungsstellung verschwenkbaren Verriegelungshebel aufweist.Furthermore, from the post-published publication EP 2 308 568 A1 a touring ski binding with a locking mechanism is known, which has a pivotable between a locking position and an unlocking locking lever.

Vor diesem Hintergrund ist es Aufgabe der vorliegenden Erfindung, eine Tourenskibindung bereitzustellen, welche einen schneller und einfacher zu bedienenden Verriegelungsmechanismus aufweist, der ein unbeabsichtigtes Auslösen der Tourenskibindung verhindern kann.Against this background, it is an object of the present invention to provide a touring ski binding, which has a faster and easier-to-use locking mechanism that can prevent unintentional triggering of touring ski binding.

Zur Lösung dieser Aufgabe schlägt die Erfindung eine Tourenskibindung vor, umfassend eine Lageranordnung, welche dafür eingerichtet ist, einen Skischuh um eine quer zu einer Skilängsachse verlaufende Skiquerachse verschwenkbar zu halten, so dass der Skischuh bewegbar ist zwischen einer ersten Schwenkstellung, in der ein Fersenabschnitt des Skischuhs an den Ski angenähert ist, und einer zweiten Schwenkstellung, in der der Fersenabschnitt des Skischuhs von dem Ski entfernt ist, wobei die Tourenskibindung einen Verriegelungsmechanismus aufweist, mit welchem die Lageranordnung so verriegelbar ist, dass ein Verschwenken des Skischuhs möglich ist, ein Lösen des Skischuhs von der Lageranordnung jedoch auch bei Ausübung einer eine Sturzauslösekraft überschreitenden Kraft verhindert ist, und wobei der Verriegelungsmechanismus ein Verriegelungsbetätigungselement aufweist, welches von dem Skischuh bei einer Schwenkbewegung des Skischuhs in die zweite Schwenkstellung betätigt wird, so dass der Verriegelungsmechanismus die Lageranordnung verriegelt.To solve this problem, the invention proposes a ski binding, comprising a bearing assembly which is adapted to pivotally hold a ski boot about a transverse to a ski longitudinal axis Skiquerachse, so that the ski boot is movable between a first pivot position, in which a heel portion of Skischuhs is approximated to the ski, and a second pivot position, in which the heel portion of the ski boot is removed from the ski, wherein the touring ski binding has a locking mechanism with which the bearing assembly is lockable so that a pivoting of the ski boot is possible, a release of the However, ski boot is prevented from the bearing assembly even when exercising a force acting on a crash trigger force, and wherein the locking mechanism comprises a locking actuator, which is actuated by the ski boot in a pivotal movement of the ski boot in the second pivot position, so that the locking mechanism locks the bearing assembly.

Unter einer Verriegelung oder einem verriegelten Zustand des Verriegelungsmechanismus wird im Sinne der vorliegenden Erfindung ein Zustand verstanden, in welchem die Lageranordnung ein Lösen des Skischuhs von der Lageranordnung auch bei Einwirkung einer eine Sturzauslösekraft überschreitenden Kraft verhindert. Dies entspricht einer Auslösekraft, die deutlich über dem oben genannten, für Skibindungen üblicherweise verwendeten Bereich von Auslösekräften liegt. Mit anderen Worten, ist der Skischuh in dem verriegelten Zustand im Wesentlichen nicht beschädigungsfrei von der Lageranordnung trennbar, während natürlich ein Verschwenken des Skischuhs weiterhin möglich ist.Under a lock or a locked state of the locking mechanism is understood in the context of the present invention, a state in which the bearing assembly, a release of the ski boot of the bearing assembly also prevents the action of a force exceeding a fall trigger force. This corresponds to a release force which is significantly above the above-mentioned range of release forces commonly used for ski bindings. In other words, the ski boot in the locked state is essentially not free of damage separable from the bearing assembly, while of course a pivoting of the ski boot is still possible.

Nach einem wichtigen Merkmal der Erfindung ist ein Verriegelungsbetätigungselement des Verriegelungsmechanismus derart vorgesehen und angeordnet, dass es betätigt wird, wenn der Skischuh in die zweite Schwenkstellung verschwenkt. Zum Verriegeln der Tourenskibindung reicht es demnach, den Skischuh in die zweite Schwenkstellung zu bewegen, d.h. den in die Bindung eingesetzten Skischuh ganz nach vorne zu kippen. Dies kann beispielsweise dadurch erfolgen, dass der Benutzer ein Knie oder beide Knie zur Skispitze hin bewegt und insbesondere vor der Bindung auf dem Ski aufsetzt, ohne dass eine zusätzliche Handbewegung oder Handbetätigung der Tourenskibindung notwendig ist.According to an important feature of the invention, a locking actuator of the locking mechanism is provided and arranged to be actuated when the ski boot pivots to the second pivot position. To lock the touring ski binding, it is therefore sufficient to move the ski boot to the second pivot position, i. tilt the ski boot used in the binding all the way to the front. This can be done, for example, by the user moving one knee or both knees towards the tip of the ski and, in particular, putting it on the ski before binding without any additional hand movement or manual operation of the touring ski binding being necessary.

Ein besonderer Vorteil der erfindungsgemäßen Tourenskibindung ergibt sich im Bereich des Wettkampfsports, in welchem das Verschwenken des Skischuhs in die zweite Schwenkstellung in ohnehin üblicherweise von Wettkampfsportlern beim Wechsel des Nutzungsmodus der Tourenskibindung vorführte Körperbewegungen integriert werden kann bzw. automatisch während solcher Bewegungen ausgeführt werden kann. So hat es sich als zeit- und kraftsparend herausgestellt, beim Lösen der Steigfelle von den Laufflächen der Ski zur Vorbereitung einer Talabfahrt niederzuknien und die Laufflächen der Skier seitlich nach außen anzuheben, so dass die Steigfelle abgezogen werden können, ohne aus der Tourenskibindung auszusteigen. Während dieser Bewegung verschwenken die Skischuhe zwangsläufig bis in die vorderste Position, also die zweite Schwenkstellung, und verriegeln den Verriegelungsmechanismus bzw. stellen eine sichere Verriegelung des Verriegelungsmechanismus sicher oder erhöhen die Verriegelungskraft des Verriegelungsmechanismus, ohne dass dafür eine zusätzliche Betätigung oder Bewegung durch den Benutzer oder ein zusätzlicher Zeitaufwand notwendig wäre.A particular advantage of the touring ski binding according to the invention results in the field of competition sports, in which the pivoting of the ski boot in the second pivot position in any case usually performed by competitive athletes when changing the mode of use of touring ski binding body movements can be integrated or can be performed automatically during such movements. So it has been found to save time and effort, kneel when loosening the skins of the treads of skis to prepare for a downhill and lift the running surfaces of the skis laterally outwards, so that the climbing skins can be deducted, without getting out of the touring ski binding. During this movement, the ski boots inevitably pivot to the foremost position, ie the second pivot position, and lock the locking mechanism or ensure a secure locking of the locking mechanism or increase the Locking force of the locking mechanism, without requiring an additional operation or movement by the user or an additional time required.

Grundsätzlich kann der Verriegelungsmechanismus so eingerichtet sein, dass eine kurze Berührung des Verriegelungsbetätigungselements zur Auslösung einer Verriegelungsbewegung führt (beispielsweise über einen Schnappmechanismus oder ein elektromechanisches Stellglied). Ein besonders einfacher Verriegelungsmechanismus kann jedoch vorteilhaft so gestaltet sein, dass das Verriegelungsbetätigungselement in einem Schwenkweg des Skischuhs zwischen der ersten Schwenkstellung und der zweiten Schwenkstellung angeordnet ist, so dass der Skischuh unter betätigender Verdrängung des Verriegelungsbetätigungselements die zweite Schwenkstellung erreicht. Die Bewegung des Skischuhs in die zweite Schwenkstellung bewirkt dann eine Bewegung des Verriegelungsbetätigungselements, wobei diese Bewegung in eine Verstellung des Verriegelungsmechanismus in die Verriegelungsstellung umgesetzt wird. So könnte die Bewegung des Skischuhs beispielsweise in einfacher Weise einen Verriegelungskörper in eine Verriegelungsposition verschieben, in der der Verriegelungskörper eine Öffnungsbewegung der Lageranordnung blockiert.In principle, the locking mechanism may be arranged such that a brief contact of the locking actuating element results in the triggering of a locking movement (for example via a snap mechanism or an electromechanical actuator). However, a particularly simple locking mechanism may advantageously be designed such that the locking actuating element is arranged in a pivoting path of the ski boot between the first pivoting position and the second pivoting position, so that the ski boot reaches the second pivoting position under actuated displacement of the locking actuating element. The movement of the ski boot into the second pivoting position then causes a movement of the locking actuating element, wherein this movement is converted into an adjustment of the locking mechanism in the locking position. For example, the movement of the ski boot could easily displace a locking body into a locking position in which the locking body blocks an opening movement of the bearing assembly.

Die Betätigung des Verriegelungsbetätigungselements erfolgt vorzugsweise nicht während des gesamten Schwenkwegs des Skischuhs sondern nur in einem Teilabschnitt des Schwenkwegs kurz vor Erreichen der zweiten Schwenkstellung des Skischuhs (z.B. im letzten Fünftel, vorzugsweise im letzten Zehntel, des Schwenkwegs vor Erreichen der zweiten Schwenkstellung), d.h. in dem Bereich, in welchem der Skischuh bereits sehr weit bis maximal nach vorne verschwenkt ist. Die normale Schwenkbewegung des Skischuhs beim normalen Gehen wird dann nicht beeinträchtigt.The actuation of the lock actuator is preferably not during the entire swing path of the ski boot but only in a portion of the swing path just prior to reaching the second pivot position of the ski boot (e.g., in the last fifth, preferably the last tenth, of the swing path before reaching the second pivot position), i. in the area in which the ski boot is already pivoted very far to maximum forward. The normal swinging motion of the ski boot during normal walking will not be affected.

In einer bevorzugten Ausführungsform der Erfindung wird bei einer Schwenkbewegung in die zweite Schwenkstellung eine fortschreitende Bewegung des Verriegelungsbetätigungselements in eine fortschreitende Erhöhung einer Spannkraft umgesetzt, mit welcher der Skischuh an der Lageranordnung gehalten wird. In einer solchen Tourenskibindung erfolgt die Verriegelung durch Erhöhung der Auslösekraft die zum Öffnen der Lageranordnung und zur Freigabe des Skischuhs notwendig ist, wobei die Auslösekraft auf einen Wert erhöht wird, der deutlich über dem üblicherweise für Skibindungen verwendeten Wertebereich liegt, so dass eine Auslösung der Tourenskibindung praktisch blockiert ist. Da für eine solche Erhöhung der Auslösekraft bzw. Erhöhung der Spannkraft der - Lageranordnung relativ hoher Kraftaufwand notwendig ist, erzielt die Bewegung des Verriegelungsbetätigungselements durch Verschwenken des Skischuhs den zusätzlichen vorteilhaften Effekt, dass dieser hohe Kraftaufwand durch die Hebelbewegung des Skischuhs vom Benutzer relativ einfach durch das Vorwärtsschwenken des Beins bzw. durch Niederknien aufgebracht werden kann.In a preferred embodiment of the invention is a progressive in a pivoting movement into the second pivot position Movement of the Verriegelungsbetätigungselements implemented in a progressive increase in a clamping force with which the ski boot is held on the bearing assembly. In such a touring ski binding, the locking is done by increasing the release force necessary to open the bearing assembly and the release of the ski boot, the release force is increased to a value that is well above the value range commonly used for ski bindings, so that triggering the touring ski binding is practically blocked. As for such an increase in the release force or increasing the clamping force of the - bearing assembly relatively high effort is necessary, the movement of the locking actuator achieved by pivoting the ski boot the additional advantageous effect that this high force by the lever movement of the ski boot by the user relatively easy by the Forward pivoting of the leg or by kneeling down can be applied.

In einer weiteren vorteilhaften Ausführungsform der Erfindung ist vorgesehen, dass der Skischuh in der zweiten Schwenkstellung um einen Winkel von ungefähr 70° bis ungefähr 110° nach vorne geschwenkt ist. In diesem Winkelbereich ist das Knie des Benutzers auf dem Ski bzw. auf dem Erdboden neben dem Ski abgesetzt, so dass die Verriegelung einfach und intuitiv erfolgen kann. Als besonders vorteilhaft hat sich ein Winkel von ungefähr 90° herausgestellt, welcher zudem einer für Tourenskibindungen geltenden Sicherheitsvorgabe entspricht. Zudem wird ein Schwenkwinkel von mehr als ungefähr 70° beim normalen Tourenskigehen während des Anstiegs nicht verwendet, so dass ein Aufstieg ohne Verriegelung der Lageranordnung, d.h. mit Sturzauslösung, möglich ist und eine Verriegelung erst im Bedarfsfall oder kurz vor einer Abfahrt durch Verschwenken des Skischuhs um einen Winkel von mehr als ungefähr 70° bzw. um einen Winkel von ungefähr 90° erfolgen kann.In a further advantageous embodiment of the invention it is provided that the ski boot is pivoted in the second pivot position by an angle of about 70 ° to about 110 ° to the front. In this angular range, the knee of the user is placed on the ski or on the ground next to the ski, so that the locking can be done easily and intuitively. Particularly advantageous is an angle of about 90 ° has been found, which also corresponds to a valid for touring ski bindings safety target. In addition, a swing angle greater than about 70 ° is not used during normal touring during the climb, so as to provide for a rise without locking the bearing assembly, i. With crash triggering, is possible and locking only when needed or just before departure by pivoting the ski boot by an angle of more than about 70 ° or at an angle of about 90 ° can take place.

Eine geringe Baugröße der erfindungsgemäßen Tourenskibindung kann erreicht werden, wenn das Verriegelungsbetätigungselement derart angeordnet ist, dass es bei der Schwenkbewegung des Skischuhs zur zweiten Schwenkstellung hin von einem vorderen Schuhkuppenabschnitt des Skischuhs kontaktiert und betätigt wird. Der vordere Schuhkuppenabschnitt des Skischuhs bewegt sich beim Verschwenken des Skischuhs zur zweiten Schwenkstellung hin nach vorne oder/und nach unten, wobei seine Bewegungskurve in der Nähe der Tourenskibindung und damit des Verriegelungsmechanismus bleibt und dadurch der Schuhkuppenabschnitt aufgrund des kurzen Hebelwegs relativ hohe Kraft auf das Verriegelungsbetätigungselement ausüben kann.A small size of the touring ski binding according to the invention can be achieved if the locking actuator such is arranged that it is contacted and operated during the pivoting movement of the ski boot to the second pivoting position of a front Schuhkuppenabschnitt the ski boot. The boot tip portion of the ski boot moves forward and / or downward as the ski boot pivots toward the second pivot position, leaving its movement cam near the toe binding and thus the locking mechanism and thereby the toe portion due to the short lever travel relatively high force on the lock actuator can exercise.

In einer weiteren bevorzugten Ausführungsform der Erfindung kann der Verriegelungsmechanismus ferner ein Verriegelungsbedienelement aufweisen, welches manuell durch einen Benutzer bedienbar ist, so dass der Verriegelungsmechanismus die Lageranordnung verriegelt, wobei das Verriegefungsbedienelement und das Verriegelungsbetätigungselement miteinander verbunden oder miteinander bewegungsgekoppelt sind. Auf diese Weise ist einerseits eine alternative oder zusätzliche Betätigung des Verriegelungsmechanismus durch Handbetätigung möglich und andererseits kann durch Verbindung oder Kopplung des Verriegelungsbetätigungselements mit dem Verriegelungsbedienelement eine herkömmliche Tourenskibindung, die über einen herkömmlichen Verriegelungsmechanismus mit Verriegelungsbedienelement verfügt, durch Bereitstellung des erfindungsgemäßen Verriegelungsbetätigungselements nachgerüstet werden, um eine erfindungsgemäße Tourenskibindung zu schaffen.In a further preferred embodiment of the invention, the locking mechanism may further comprise a locking operator manually operable by a user such that the locking mechanism locks the bearing assembly, wherein the locking actuator and the locking actuator are interconnected or motion coupled together. In this way, on the one hand, an alternative or additional operation of the locking mechanism by manual operation is possible and on the other hand can be retrofitted by providing the locking actuator according to the invention by connecting or coupling the Verriegelungsbetätigungselements with the locking control a conventional touring ski binding, which has a conventional locking mechanism with locking control element To create touring ski binding according to the invention.

Vorzugsweise umfasst die Tourenskibindung der Erfindung ferner einen Auslösemechanismus, welcher bei Einwirkung einer eine vorbestimmte Auslösekraft überschreitenden Kraft auslöst, um den Skischuh von der Lageranordnung freizugeben, wobei der Verriegelungsmechanismus den Auslösemechanismus blockiert. Ein solcher Auslösemechanismus weist in an sich bekannter Weise häufig federnd gelagerte, bewegliche Teile auf, welche durch den erfindungsgemäßen Verriegelungsmechanismus einfach und wirkungsvoll in ihrer Bewegung blockiert werden können.Preferably, the toe binding of the invention further comprises a triggering mechanism which, upon application of a force exceeding a predetermined release force, releases the ski boot from the bearing assembly, the locking mechanism blocking the triggering mechanism. Such a trigger mechanism often has, in a manner known per se, spring-mounted, movable parts which can be easily and effectively blocked in their movement by the locking mechanism according to the invention.

In einer weiteren bevorzugten Ausführungsform ist vorgesehen, dass die Lageranordnung zwei seitliche Lagerelemente umfasst, welche auf der Skiquerachse angeordnet sind und welche dafür eingerichtet sind, seitliche Gegenlagerelemente des Skischuhs in Eingriff zu nehmen, um den Skischuh um die Skiquerachse verschwenkbar zu halten, wobei die Lagerelemente bewegbar sind zwischen einer Schließstellung, in welcher die Lagerelemente voneinander einen Abstand aufweisen, der für einen Eingriff mit den Gegenlagerelementen ausgelegt ist, und einer Öffnungsstellung, in welcher die Lagerelemente einen Abstand aufweisen, der größer ist als in der Schließstellung, so dass der Skischuh zwischen den Lagerelementen eingeführt oder von der Tourenskibindung entfernt werden kann. Eine Lageranordnung mit derart zwischen Schließstellung und Öffnungsstellung bewegbaren Lagerelementen ist an sich im Stand der Technik bekannt und hat sich im Tourenskisport als Standard etabliert. Standardisierte Abmessungen weisen dementsprechend auch die für solche Lageranordnungen passenden Skischuhe auf, so dass auch die Bewegungsbahn des Skischuhs vordefiniert ist und das erfindungsgemäße Verriegelungsbetätigungselement in vorbestimmter Art angeordnet und eingerichtet werden kann. Der Verriegelungsmechanismus bewirkt dann eine Verriegelung der Bewegung der Lagerelemente zwischen Schließstellung und Öffnungsstellung, so dass die Lagerelemente sicher in der Schließstellung gehalten werden und sich nicht soweit auseinander bewegen können, dass der Skischuh zwischen den Lagerelementen herausgleiten kann.In a further preferred embodiment, it is provided that the bearing arrangement comprises two lateral bearing elements, which are arranged on the Skiquerachse and which are adapted to take lateral abutment elements of the ski boot to hold the ski boot pivotable about the Skiquerachse, wherein the bearing elements are movable between a closed position in which the bearing elements have a distance from each other, which is designed for engagement with the abutment elements, and an open position in which the bearing elements have a distance which is greater than in the closed position, so that the ski boot between introduced the bearing elements or can be removed from the touring ski binding. A bearing assembly with such movable between closed position and open position bearing elements is known per se in the art and has become established in touring skis as a standard. Accordingly, standardized dimensions also have the ski boots which are suitable for such bearing arrangements, so that the movement path of the ski boot is also predefined and the locking actuating element according to the invention can be arranged and set up in a predetermined manner. The locking mechanism then causes a locking of the movement of the bearing elements between the closed position and open position, so that the bearing elements are securely held in the closed position and can not move apart so far that the ski boot can slide out between the bearing elements.

In einer Tourenskibindung mit seitlichen bewegbaren Lagerelementen ist es ferner an sich bekannt, ein Bindungsbetätigungselement zur Betätigung der Tourenskibindung bereitzustellen, wobei das Bindungsbetätigungselement und die Lagerelemente miteinander bewegungsgekoppelt sind. In einer Ausführungsform der Erfindung kann der erfindungsgemäße Verriegelungsmechanismus eine Bewegung des Bindungsbetätigungsabschnitts von der Schließstellung in die Öffnungsstellung blockieren. Somit muss der Verriegelungsmechanismus nicht unmittelbar auf die Lagerelemente einwirken sondern kann an kinematisch und in Hinblick auf den Bauraum vorteilhafter Position am Bindungsbetätigungselement wirken.In a touring ski binding with laterally movable bearing elements, it is also known per se to provide a binding actuating element for actuating the touring ski binding, wherein the binding actuating element and the bearing elements are motion-coupled with each other. In one embodiment of the invention, the locking mechanism according to the invention may block movement of the binding operation portion from the closed position to the open position. Thus, the locking mechanism does not have to act directly on the bearing elements but can act on kinematic and in terms of space advantageous position on the binding actuator.

Die vorstehend genannte Ausführungsform einer erfindungsgemäßen Tourenskibindung mit seitlichen Lagerelementen und Bindungsbetätigungselement kann in einer bevorzugten Weiterbildung ferner zwei Klemmwinkel umfassen, welche jeweils um eine zur Skimittelachse parallele Achse verschwenkbar gehalten sind, wobei jeder der Klemmwinkel einen ersten Schenkel aufweist, an dessen distalen Ende eines der Lagerelemente angeordnet ist, und einen zweiten Schenkel aufweist, dessen distales Ende zu dem jeweils anderen Klemmwinkel hin weist, wobei das Bindungsbetätigungselement ein um eine zu einer Skiebene im Wesentlichen parallele Achse verschwenkbar gelagerter, zweiarmiger Bindungsbetätigungshebel ist, dessen erster Arm auf die beiden distalen Enden der zweiten Schenkel der Klemmwinkel wirkt und an dessen zweiten Arm ein Betätigungsabschnitt zur manuellen Betätigung angeordnet ist. Das Bindungsbetätigungselement in Form eines Bindungsbetätigungshebels erlaubt die Bewegung beider Klemmwinkel, d.h. beider Lagerelemente, zwischen Öffnungs- und Schließstellung. Der Betätigungsabschnitt kann entweder per Hand oder mit der Spitze eines Skistocks betätigt werden, insbesondere um die Tourenskibindung zu öffnen. Ein Blockieren der Bewegung dieses Bindungsbetätigungshebels stellt eine konstruktiv einfache und wirkungsvolle Möglichkeit zur Verriegelung der Tourenskibindung dar.The above-mentioned embodiment of a touring ski binding according to the invention with lateral bearing elements and binding actuation element may further comprise two clamping angles, which are each held pivotable about an axis parallel to the ski center axis, each of the clamping angle having a first leg, at the distal end of one of the bearing elements is arranged, and has a second leg, the distal end of which points to the other clamping angle, wherein the binding actuator is a pivotally mounted about a substantially parallel to a Skiebene axis, two-armed binding lever, the first arm on the two distal ends of the second Leg of the clamping angle acts and on the second arm an actuating portion is arranged for manual operation. The binding actuator in the form of a binding actuating lever allows the movement of both clamping angles, i. both bearing elements, between open and closed position. The actuating portion can be operated either by hand or with the tip of a ski pole, in particular to open the touring ski binding. Blocking the movement of this binding actuating lever provides a structurally simple and effective way to lock the touring ski binding.

So ist eine Möglichkeit zur Verriegelung eines solchen Bindungsbetätigungshebels die Bereitstellung eines Verriegelungskörpers des Verriegelungsmechanismus, welcher schwenkbar an dem zweiten Arm des Bindungsbetätigungshebels angebracht ist, wobei dann das Verriegelungsbetätigungselement so mit dem Verriegelungskörper gekoppelt oder verbunden ist, dass eine Bewegung des Verriegelungsbetätigungselements beim Verschwenken des Skischuhs in die zweite Schwenkstellung den Verriegelungskörper in eine Verriegelungsstellung verschwenkt, in welcher der Verriegelungskörper zwischen dem zweiten Arm des Bindungsbetätigungshebels und dem Ski angeordnet ist, so dass eine Schwenkbewegung des Bindungsbetätigungshebels von der Schließstellung in die Öffnungsstellung blockiert ist. Auf diese Weise kann die Schwenkbewegung des Skischuhs vor dem Erreichen der zweiten Schwenkstellung in einfacher Weise in eine Schwenkbewegung des Verriegelungsbetätigungselements und schließlich in eine Schwenkbewegung des Verriegelungskörpers in eine Verriegelungsstellung umgesetzt werden. Wenn Verriegelungsbetätigungselement und Verriegelungskörper drehfest miteinander verbunden oder sogar integral miteinander ausgebildet sind, so kann der Verriegelungsmechanismus mit nur einer Schwenkachse, an welcher Verriegelungskörper und Verriegelungsbetätigungselement schwenkbar sind, konstruktiv einfach realisiert werden.Thus, one way to lock such a binding actuating lever is to provide a locking body of the locking mechanism pivotally attached to the second arm of the binding actuating lever, in which case the locking actuating element is coupled or connected to the locking body such that movement of the locking actuating element during pivoting of the ski boot into the second pivoting position pivots the locking body into a locking position, in which the locking body between the second arm of the binding actuating lever and the ski is arranged so that a pivoting movement of the binding actuating lever is blocked from the closed position to the open position. In this way, the pivotal movement of the ski boot can be implemented in a simple manner in a pivoting movement of the locking actuating element and finally in a pivotal movement of the locking body in a locking position before reaching the second pivot position. If locking actuator and locking body rotatably connected to each other or even integrally formed with each other, so the locking mechanism can be realized structurally simple with only one pivot axis, on which locking body and locking actuator are pivotable.

In einer weiteren bevorzugten Weiterbildung einer erfindungsgemäßen Tourenskibindung mit dem genannten Verriegelungskörper wird ferner ein Nockenmechanismus vorgeschlagen, welcher eine fortschreitende Schwenkbewegung des Verriegelungskörpers zur Verriegelungsstellung hin umsetzt in eine fortschreitende Schwenkbewegung des Bindungsbetätigungshebels in Schließrichtung zur fortschreitenden Erhöhung einer zwischen den Lagerelementen wirkende Spannkraft, mit welcher der Skischuh an der Lageranordnung gehalten wird. Somit wird die Tourenskibindung bei fortschreitender Schwenkbewegung des Skischuhs zur zweiten Schwenkstellung hin fortschreitend gespannt, wobei aufgrund der Hebelwirkung über den Skischuh eine hohe Kraft zum zuverlässigen Spannen und Verriegeln des Verriegelungsmechanismus ausgeübt werden kann.In a further preferred embodiment of a touring ski binding according to the invention with the said locking body, a cam mechanism is further proposed, which converts a progressive pivoting movement of the locking body to the locking position in a progressive pivotal movement of the binding actuating lever in the closing direction to progressively increase a force acting between the bearing elements clamping force with which the ski boot is held on the bearing assembly. Thus, the ski binding is progressively stretched towards the second pivotal position as the pivotal movement of the ski boot progresses, whereby due to the leverage effect over the ski boot, a high force can be exerted for reliable tightening and locking of the locking mechanism.

An der Basisplatte 12 sind zwei Klemmwinkel 18a, 18b über jeweils eine parallel zu einer Skimittelachse M verlaufende Schwenkachse 20a, 20b gehalten, sodass die Klemmwinkel 18a, 18b um die Schwenkachsen 20a, 20b verschwenkbar sind. Jeder Klemmwinkel 18a bzw. 18b umfasst einen ersten Schenkel 22a, 22b, welcher bezüglich einer durch den Ski 16 definierten Skiebene E (die zur Lauffläche 24 des Skis 16 parallele Ebene E, in der die Oberfläche 25 des Skis 16 liegt) nach oben aufragt, d.h. sich ungefähr in einer orthogonal zur Skiebene E verlaufenden Höhenrichtung erstreckt. Ferner umfasst jeder Klemmwinkel 18a, 18b einen zweiten Schenkel 26a, 26b, der sich vom ersten Schenkel 22a, 22b aus zur Skimittelachse M des Skis 16 hin erstreckt und ungefähr parallel zur Skiebene E orientiert ist.Two clamping angles 18a, 18b are held on the base plate 12 via a respective pivot axis 20a, 20b running parallel to a ski center axis M, so that the clamping angles 18a, 18b are pivotable about the pivot axes 20a, 20b. Each clamping angle 18a or 18b comprises a first leg 22a, 22b which projects upwards with respect to a ski plane E defined by the ski 16 (the plane E parallel to the running surface 24 of the ski 16 in which the surface 25 of the ski 16 lies), ie extends approximately in an orthogonal to the skiebene E extending height direction. Furthermore, each clamping angle 18a, 18b comprises a second leg 26a, 26b, which extends from the first leg 22a, 22b out to the ski center axis M of the ski 16 and is oriented approximately parallel to the plane E of the ski.

Distale Enden 28a, 28b (von den Schwenkachsen 20a, 20b entfernte Enden) der zweiten Schenkel 26a, 26b der Klemmwinkel 18a, 18b sind durch jeweils zwei an den zweiten Schenkeln 26a, 26b befestigte Stifte (nicht dargestellt) in Richtung zur Skimittelachse M hin verlängert. Die Stifte sind mit ihren zur Skimittelachse M hin weisenden Enden verschiebbar in Löcher von Endkappen 32a, 32b eingeführt, wobei die beiden Stifte des einen Klemmwinkel 18a in jeweils zwei Löcher einer gemeinsamen ersten Endkappe 32a eingeschoben sind und die beiden Stifte des anderen Klemmwinkels 18b in zwei Löcher einer gemeinsamen zweiten Endkappe 32b eingeführt sind. Um jeden der vier Stifte sind jeweils Spiralfedern 34 gewunden, wobei sich jede der Spiralfedern 34 jeweils einerseits am distalen Ende 28a, 28b des Klemmwinkels 18a, 18b und andererseits an der Endkappe 32a, 32b abstützt, um die Endkappen 32a, 32b in einer von den Klemmwinkeln 18a, 18b wegführenden Richtung, d.h. in Richtung einer Annäherung der beiden Endkappen 32a, 32b aneinander, vorzuspannen, sodass die Endkappen 32a, 32b aneinander anliegen und gegeneinander gedrückt werden.Distal ends 28a, 28b (ends remote from the pivot axes 20a, 20b) of the second legs 26a, 26b are the clamping angles 18a, 18b, respectively two pins (not shown) attached to the second legs 26a, 26b extend in the direction of the ski center axis M. The pins are slidably inserted with their ends pointing towards the ski center axis M in holes of end caps 32a, 32b, wherein the two pins of a clamping bracket 18a are inserted into two holes of a common first end cap 32a and the two pins of the other clamping bracket 18b in two Holes of a common second end cap 32b are inserted. Spiral springs 34 are wound around each of the four pins, each of the coil springs 34 being supported on the one hand at the distal end 28a, 28b of the clamping bracket 18a, 18b and on the other end on the end cap 32a, 32b, in one of the end caps 32a, 32b Clamping angles 18a, 18b wegführenden direction, ie in the direction of an approach of the two end caps 32a, 32b to each other, bias, so that the end caps 32a, 32b abut each other and are pressed against each other.

Distale Enden der ersten Schenkel 22a, 22b weisen jeweils einen Lagerzapfen 35a, 35b auf, welche von dem ersten Schenkel 22a, 22b aus jeweils nach innen, d.h. zur Skimittelachse M hin, vorstehen und an ihren vorstehenden Enden konusförmig spitz zulaufen. Die Spitzen der Lagerzapfen 35a, 35b weisen somit in etwa aufeinander zu.Distal ends of the first legs 22a, 22b each have a journal 35a, 35b which extends inwardly from the first leg 22a, 22b, respectively. towards the ski center axis M, projecting and tapering conically at their projecting ends. The tips of the bearing journals 35a, 35b thus point approximately toward one another.

An der Basisplatte 12 ist ferner ein zweiarmiger Betätigungshebel 37 um eine im Wesentlichen orthogonal zur Skimittelachse M und im Wesentlichen parallel zur Skiebene E verlaufende Betätigungshebel-Schwenkachse 36 schwenkbar gehalten. Ein erster Arm 38 des Betätigungshebels 37 erstreckt sich von der Betätigungshebel-Schwenkachse 36 aus zu den Endkappen 32a, 32b der Klemmwinkel 18a, 18b hin und ergreift die Endkappen 32a, 32b mit einem gabelartigen Endabschnitt 40. Dazu weist der gabelartige Endabschnitt 40 einen ersten Plattenabschnitt 42 auf, der sich von dem ersten Arm 38 aus ein Stück weit über die Endkappen 32a, 32b hinweg erstreckt, und weist einen zweiten Plattenabschnitt 44 auf, welcher sich von dem ersten Arm 38 aus ein Stück weit unterhalb beider Endkappen 32a, 32b erstreckt. Die Endkappen 32a, 32b sind somit zwischen den Plattenabschnitten 42, 44 des Betätigungshebels 37 aufgenommen und eine Schwenkbewegung des Betätigungshebels 37 um die Betätigungshebel-Schwenkachse 36 ist bewegungsgekoppelt mit einer Schwenkbewegung der Klemmwinkel 18a, 18b um die Schwenkachsen 20a, 20b.On the base plate 12, a two-armed actuating lever 37 is further pivotally held about an actuating lever pivot axis 36 extending substantially orthogonal to the ski center axis M and substantially parallel to the skiebene E. A first arm 38 of the operating lever 37 extends from the operating lever pivot axis 36 toward the end caps 32a, 32b of the clamping brackets 18a, 18b and engages the end caps 32a, 32b with a forked end portion 40. For this, the forked end portion 40 has a first plate portion 42 extending from the first arm 38 a distance beyond the end caps 32a, 32b, and has a second plate portion 44 extending from the first arm 38 a distance below both end caps 32a, 32b. The end caps 32a, 32b are thus between the plate sections 42, 44 the actuating lever 37 is received and a pivoting movement of the actuating lever 37 about the actuating lever pivot axis 36 is coupled for movement with a pivoting movement of the clamping angle 18a, 18b about the pivot axes 20a, 20b.

Ein zweiter Arm 46 des Betätigungshebels 37 erstreckt sich von der Betätigungshebel-Schwenkachse 36 aus im Wesentlichen in entgegengesetzter Richtung zum ersten Arm 38 und ist an seinem distalen Ende mit einem Verriegelungshebel 48 verbunden. Der Verriegelungshebel 48 ist am distalen Ende des zweiten Arms 46 an einer zur Skimittelachse M im Wesentlichen orthogonalen und zur Skiebene E im Wesentlichen parallelen Verriegelungshebel-Schwenkachse 50 schwenkbar gelagert, und weist einen Verriegelungsbedienabschnitt 52 sowie einen Blockierabschnitt 54 auf, welche im Ausführungsbeispiel einstückig miteinander ausgebildet sind und sich von der Verriegelungshebel-Schwenkachse 50 aus in unterschiedlichen, insbesondere im Wesentlichen entgegengesetzten, Richtungen erstrecken.A second arm 46 of the actuating lever 37 extends from the operating lever pivot axis 36 in substantially the opposite direction to the first arm 38 and is connected at its distal end to a locking lever 48. The locking lever 48 is pivotally mounted at the distal end of the second arm 46 at a substantially perpendicular to the ski center axis M and substantially parallel to Skiebene E locking arm pivot axis 50, and has a Verriegelungsbedienabschnitt 52 and a blocking portion 54 which formed integrally with each other in the embodiment are and extend from the locking lever pivot axis 50 in different, in particular substantially opposite, directions.

Der Verriegelungshebel 48 ist durch eine um die Verriegelungshebel-Schwenkachse 50 gewundene Spiralfeder, welche sich mit einem Ende am Verriegelungshebel 48 abstützt und mit ihrem anderen Ende am Betätigungshebel 37 anliegt, in Richtung einer Verriegelungsstellung des Verriegelungshebels 48 vorgespannt (in Figuren 3 bis 5 im Uhrzeigersinn).The locking lever 48 is biased by a coiled about the locking lever pivot axis 50 spiral spring, which is supported at one end on the locking lever 48 and abuts with its other end on the actuating lever 37 in the direction of a locking position of the locking lever 48 (in FIGS. 3 to 5 clockwise).

An dem Verriegelungshebel 48 ist ferner ein bügelartiges Verriegelungsbetätigungselement 58 drehfest angebracht, so dass eine Schwenkbewegung des Verriegelungsbetätigungselements 58 den Verriegelungshebel 48 um die Verriegelungshebel-Schwenkachse 50 dreht. Das Verriegelungsbetätigungselement 58 könnte alternativ einstückig mit dem Verriegelungshebel 48 verbunden sein.On the locking lever 48, a bow-like locking actuator 58 is further rotatably mounted, so that a pivoting movement of the locking actuator 58 rotates the locking lever 48 about the locking lever pivot axis 50. The latch actuator 58 could alternatively be integrally connected to the latch lever 48.

Wie in Figuren 3 bis 5 zu erkennen ist, erstreckt sich das Verriegelungsbetätigungselement 58 von dem Verriegelungshebel 48 aus (z.B. in etwa von der Verriegelungshebel-Schwenkachse 50 aus) zu einer Position hin, welche im Schwenkweg eines Skischuhs 60, insbesondere eines vorderen Kuppenabschnitts 62 eines Skischuhs 60, liegt, wenn der Skischuh 60 an seitlichen Lagerlöchern 64 von den Lagerzapfen 35a, 35b in Eingriff genommen wird und um die Achse der Lagerzapfen 35a, 35b, d.h. um die Querachse Q, verschwenkt. Der vordere Kuppenabschnitt 62 kann somit, wie später noch ausführlicher erläutert wird, bei seiner Schwenkbewegung nach vorne das Verriegelungsbetätigungselement 58 kontaktieren und verschwenken.As in FIGS. 3 to 5 1, the lock actuator 58 extends from the lock lever 48 (eg, approximately from the lock lever pivot axis 50) to a position which in the pivoting path of a ski boot 60, in particular a front tip portion 62 of a ski boot 60, when the ski boot 60 is engaged on lateral bearing holes 64 of the bearing pins 35a, 35b and about the axis of the bearing pins 35a, 35b, ie about the transverse axis Q , pivoted. The front tip portion 62 can thus, as will be explained in more detail later, in its pivotal movement forward contact the locking actuator 58 and pivot.

Die Funktionsweise der Tourenskibindung 10 des Ausführungsbeispiels der Erfindung wird nachfolgend unter Bezugnahme vor allem auf Figuren 3 bis 5 näher erläutert. Ein Benutzer kann mit einem Skischuh 60 in die Tourenskibindung 10 einsteigen, wenn sich die Klemmwinkel 18a, 18b in der in Figur 3 gezeigten Öffnungsstellung befinden, in welcher die Endkappen 32a, 32b mit dem gabelartigen Endabschnitt 40 des Betätigungshebels 37 in die obere Stellung bewegt sind und die Lagerzapfen 35a, 35b dementsprechend nach außen weg geschwenkt sind. Die Lagerzapfen 35a, 35b sind dann soweit voneinander entfernt, dass ein Sohlenabschnitt 63 des Skischuhs 60 zwischen diesen eingeschobenen werden kann. Der Verriegelungshebel 48 ist in der Öffnungsstellung so angeordnet, dass der Verriegelungsbedienabschnitt 52 im Wesentlichen parallel zur Skiebene E nach vorne verläuft und der Blockerbabschnitt 54 durch die Kraft der Feder 56 gegen die Basisplatte 12 gedrückt wird (Figur 3).The operation of the touring ski binding 10 of the embodiment of the invention will be described below with reference in particular FIGS. 3 to 5 explained in more detail. A user may enter the touring ski binding 10 with a ski boot 60 when the clamping angles 18a, 18b in the touring ski binding 10 are in place FIG. 3 shown in which the end caps 32a, 32b are moved to the fork-like end portion 40 of the actuating lever 37 in the upper position and the bearing pins 35a, 35b are pivoted accordingly outwardly. The bearing journals 35a, 35b are then so far away from each other that a sole portion 63 of the ski boot 60 can be inserted between them. The locking lever 48 is arranged in the open position so that the locking operation portion 52 extends forward substantially parallel to the skid E and the blocker portion 54 is pressed by the force of the spring 56 against the base plate 12 ( FIG. 3 ).

Zum Einsetzen eines Skischuhs und Schließen der Tourenskibindung 10 wird ein Skischuh 60 mit einer Lauffläche 66 seines Sohlenabschnitts 63 von oben auf dem ersten Plattenabschnitt 42 des gabelartigen Endabschnitts 40 des Betätigungshebels 37 abgesetzt. Anschließend wird der gabelartige Endabschnitt 40 durch Ausübung einer zum Ski 16 hin gerichteten Kraft durch den Skischuh 60 oder/und durch manuelle Schwenkbetätigung des Betätigungshebel 37 zum Ski 16 hin bewegt. Der gabelartige Endabschnitt 40 nimmt dabei die Endkappen 32a, 32b mit und verschwenkt die Klemmwinkel 18a, 18b um die Schwenkachsen 20a, 20b. Dementsprechend nähern sich die Lagerzapfen 35a, 35b einander an und bewegen sich in Richtung des Skischuhs 60. Diese Bewegung erfolgt gegen den Widerstand der Spiralfedern 34, da ein Kontaktbereichs 70 zwischen den Endkappen 32a, 32b in der Öffnungsstellung oberhalb einer Verbindungslinie v zwischen den Schwenkachsen 20a, 20b liegt und somit eine Annäherung des Kontaktbereichs 70 an die Verbindungslinie v eine Verkleinerung der jeweiligen Abstände zwischen den Endkappen 32a, 32b und den Klemmwinkeln 18a, 18b und damit eine Komprimierung der Spiralfedern 34 bedeutet.To insert a ski boot and close the touring ski binding 10, a ski boot 60 with a running surface 66 of its sole portion 63 is placed from above on the first plate portion 42 of the fork-like end portion 40 of the operating lever 37. Subsequently, the fork-like end portion 40 is moved by exercising a ski 16 towards the directed force through the ski boot 60 and / or by manual pivoting operation of the operating lever 37 to the ski 16 out. The fork-like end portion 40 takes with the end caps 32a, 32b and pivots the clamping bracket 18a, 18b about the pivot axes 20a, 20b. Accordingly The bearing pins 35a, 35b approach each other and move in the direction of the ski boot 60. This movement takes place against the resistance of the coil springs 34, since a contact region 70 between the end caps 32a, 32b in the open position above a connecting line v between the pivot axes 20a, 20b and thus an approximation of the contact region 70 to the connecting line v means a reduction of the respective distances between the end caps 32a, 32b and the clamping angles 18a, 18b and thus a compression of the coil springs 34 means.

Wenn sich die Endkappen 32a, 32b in etwa auf Höhe der Verbindungslinie v befinden, so erreicht die Bewegungseinrichtung einen Totpunkt, in welchem der Widerstand der Spiralfedern 34 gegen die Annäherung der Endkappen 32a, 32b an die Verbindungslinie v umspringt in eine durch die Kraft der Federn 34 hervorgerufene Beschleunigung der Endkappen 32a, 32b in Richtung einer weiteren Annäherung an den Ski 16. Die Kraft der Spiralfedern 34, die also die Endkappen 35a, 35b stets von der Verbindungslinie v wegrückt, lässt somit die Bewegungseinrichtung am Totpunkt umspringen und drückt die Klemmwinkel selbsttätig in Richtung einer Schließstellung, in welcher die Lagerzapfen 35a, 35b in Richtung gegenseitiger Annäherung vorgespannt sind.When the end caps 32a, 32b are approximately at the level of the connecting line v, the moving means reaches a dead center in which the resistance of the coil springs 34 against the approach of the end caps 32a, 32b to the connecting line v jumps to one by the force of the springs 34 induced acceleration of the end caps 32a, 32b in the direction of a further approach to the ski 16. The force of the coil springs 34, so the end caps 35a, 35b always moves away from the connecting line v, thus allows the moving device at the dead center and presses the clamping angle automatically in the direction of a closed position, in which the bearing pins 35a, 35b are biased in the direction of mutual approach.

Spätestens beim Durchlaufen des Totpunkt weist der erste Plattenabschnitt 42 eine Höhe über dem Ski 16 auf, die den darauf abgestützten Skischuh 60 in einer korrekten Höhe in Bezug auf die Lagerzapfen 35a, 35b positioniert, so dass sich die Lagerlöcher 68 des Skischuhs 64 in etwa auf gleicher Höhe befinden wie die Lagerzapfen 35a, 35b, so dass bei der weiteren Bewegung der Bewegungseinrichtung in die Schließstellung die Lagerzapfen 35a, 35b sicher in die Lagerlöcher 68 eingreifen können.At the latest when passing through the dead center, the first plate portion 42 has a height above the ski 16, which positions the ski boot 60 supported thereon at a correct height with respect to the bearing journals 35a, 35b, so that the bearing holes 68 of the ski boot 64 approximately the same height as the bearing pins 35a, 35b, so that in the further movement of the movement means in the closed position, the bearing pins 35a, 35b can securely engage in the bearing holes 68.

In der durch das Umspringen der Klemmwinkel 18a, 18b selbsttätig eingestellten Schließstellung ist der zweite Arm 46 des_Betätigungshebels 37 so weit nach oben verschwenkt, dass die Feder 56 den Verriegelungshebel 48 weiter im Uhrzeigersinn verschwenken konnte, bis der Blockierabschnitt 54 fast in einer Position unterhalb der Verriegelungshebel-Schwenkachse 50 angeordnet ist. In diesem Zustand kann die Tourenskibindung bei entsprechender Kraftausübung auf den Skischuh noch immer auslösen, indem die Klemmwinkel 18a, 18b gegen die Kraft der Spiralfedern 34 nach außen verschwenkt werden und indem auch der Betätigungshebel 37 den Verriegelungshebel 48 gegen die Kraft der Feder 56 wieder in Richtung Öffnungsstellung (entgegen dem Uhrzeigersinn in Figur 4) verschwenkt.In the automatically closed by the jumping of the clamping bracket 18a, 18b closed position, the second arm 46 of the actuating lever 37 is pivoted so far upwards that the spring 56, the locking lever 48th could continue to pivot in a clockwise direction until the blocking portion 54 is disposed almost in a position below the locking lever pivot axis 50. In this state, the touring ski binding can still trigger with appropriate exertion of force on the ski boot by the clamping bracket 18a, 18b pivoted against the force of the coil springs 34 to the outside and by also the operating lever 37, the locking lever 48 against the force of the spring 56 back in the direction Open position (counterclockwise in FIG. 4 ) pivots.

Zur erfindungsgemäßen sicheren Verriegelung der Tourenskibindung 10 wird der Skischuh 60 nach vorne verschwenkt (Pfeil A), bis er nahezu orthogonal, zum Beispiel in einem Winkel W von ungefähr 80°, zur Skiebene E angeordnet ist. Während dieser Schwenkbewegung trifft der vordere Schuhkuppenabschnitt 62 auf das Verriegelungsbetätigungselement 58 und drückt dieses nach unten (Pfeil B). Der mit dem Verriegelungsbetätigungselement 58 verbundene Verriegelungshebel 48 wird dabei weiter in Richtung der Spannkraft der Feder 56 so verdreht, dass sich der Blockierabschnitt 54 weiter in eine Verriegelungsstellung zwischen die Verriegelungshebel-Schwenkachse 50 und den Ski 16 schiebt und dabei auf einen Nocken 72 auffährt (Pfeil C).For the inventive secure locking of touring ski binding 10 of the ski boot 60 is pivoted forwardly (arrow A) until it is almost orthogonal, for example, at an angle W of approximately 80 °, arranged for Skiebene E. During this pivotal movement, the front shoe tip portion 62 strikes the lock actuator 58 and pushes it downwards (arrow B). The connected to the locking actuator 58 locking lever 48 is further rotated in the direction of the clamping force of the spring 56 so that the blocking portion 54 further pushes into a locking position between the locking lever pivot axis 50 and the ski 16 while on a cam 72 auffahren (arrow C).

Die Formen des Nockens 72 und des Blockierabschnitts 54 sind so aufeinander abgestimmt, dass bei fortschreitender Verschwenkung des Verriegelungshebels 48 in Folge fortschreitender Abwärts-Verschwenkung des Verriegelungsbetätigungselements 58 der zweite Arm 46 des Betätigungshebels 37 fortschreitend angehoben wird. Dementsprechend werden der erste Arm 38 des Betätigungshebels 37 und mit diesem die Endkappen 32a, 32b der Klemmwinkel 18a, 18b fortschreitend weiter nach unten gespannt und die Lagerzapfen 35a, 35b werden in fortschreitend festeren Eingriff in die Lagerlöcher 68 gedrückt. Auf diese Weise wird die zum Lösen des Skischuhs 60 aus der Tourenskibindung notwendige Auslösekraft während des Verschwenkens des Verriegelungsbetätigungselements 58 sehr schnell auf Werte gesteigert, die einer quasi vollständigen Verriegelung der Tourenskibindung entsprechen, so dass der Skischuh 60 praktisch nicht beschädigungsfrei aus der Tourenskibindung 10 gelöst werden kann. Der verriegelte Zustand entspricht im Ausführungsbeispiel einem Auslösedrehmoment um die Skinormale von mehr als ungefähr Z12, insbesondere mehr als ungefähr Z16.The shapes of the cam 72 and the blocking portion 54 are coordinated so that as the locking lever 48 progressively pivots as a result of progressive downward pivoting of the locking actuator 58, the second arm 46 of the operating lever 37 is progressively raised. Accordingly, the first arm 38 of the operating lever 37 and, with this, the end caps 32a, 32b of the clamping brackets 18a, 18b are progressively further biased downwardly and the journal pins 35a, 35b are pressed into the bearing holes 68 in progressively stronger engagement. In this way, the release force necessary for releasing the ski boot 60 from the touring ski binding during the pivoting of the locking actuating element 58 is increased very quickly to values which are virtually complete locking correspond to the touring ski binding, so that the ski boot 60 can not be solved without damage from the touring ski binding 10 virtually. In the exemplary embodiment, the locked state corresponds to a triggering torque around the skin normal of more than approximately Z12, in particular more than approximately Z16.

Wenn der Skischuh 60 die maximale vordere Schwenkstellung (zweite Schwenkstellung) erreicht, in welcher er im Wesentlichen orthogonal zur Skiebene E verläuft, so dass ein Fersenabschnitt des Skischuhs 60 orthogonal vom Ski nach oben weist, so ist der Blockierabschnitt 54 vollständig auf den Nocken 72 aufgefahren und der Betätigungshebel 37 hat die Klemmhebel 18a, 18b mit maximaler Spannkraft in der Schließstellung verriegelt. Ein unbeabsichtigtes Öffnen oder Auslösen der Tourenskibindung ist nun nicht mehr möglich, da zur Verschwenkung der Klemmwinkel18a, 18b in Öffnungsrichtung der Betätigungshebel 37 verschwenkt werden müsste, diese Schwenkbewegung jedoch durch den Blockierabschnitt 54 blockiert ist, der in dem Schwenkweg zwischen dem zweiten Arm 46 des Betätigungshebels 37 und der Basisplatte 12 positioniert ist.When the ski boot 60 reaches the maximum forward pivot position (second pivot position) in which it is substantially orthogonal to the skid E, so that a heel portion of the ski boot 60 is orthogonal to the ski, the blocking portion 54 has fully extended onto the cam 72 and the operating lever 37 has locked the clamping levers 18a, 18b with maximum clamping force in the closed position. Unintentional opening or release of the touring ski binding is now no longer possible, since for pivoting the Klemmwinkel18a, 18b in the opening direction of the actuating lever 37 should be pivoted, this pivoting movement is blocked by the blocking portion 54 in the pivoting path between the second arm 46 of the actuating lever 37 and the base plate 12 is positioned.

Zum Öffnen der Tourenskibindung 10 wird zunächst der Verriegelungshebel 48 von der Verriegelungsstellung zurück verschwenkt, so dass der Blockierabschnitt 54 von dem Nocken 72 gelöst ist. Anschließend wird der Verriegelungshebel 48 am Verriegelungsbedienabschnitt 52 ergriffen und zum Ski 16 hinbewegt, so dass der Betätigungshebel 37 verschwenkt und der gabelartige Endabschnitt 40 sich nach oben bewegt. Dabei setzt die Bewegungseinrichtung dieser Öffnungsbewegung solange den Widerstand der Spiralfedern 34 entgegen, bis die Endkappen 32a, 32b wiederum den Totpunkt in Höhe der Verbindungslinie v zwischen den Schwenkachsen 20a, 20b durchlaufen. Danach drücken die Federn 34 die Endkappen 32a, 32b selbsttätig weiter nach oben in Richtung der Öffnungsstellung und halten die Klemmwinkel 18a, 18b schließlich in der Öffnungsstellung. Die Lagerzapfen 35a, 35b lösen sich dabei aus dem Eingriff mit den Lagerlöchern 68 und der Skischuh 60 kann schließlich aus der Tourenskibindung herausgezogen werden.To open the touring ski binding 10, the locking lever 48 is first pivoted back from the locking position, so that the blocking portion 54 is released from the cam 72. Subsequently, the lock lever 48 is gripped on the lock operation portion 52 and moved toward the ski 16, so that the operation lever 37 pivots and the fork-like end portion 40 moves upward. In this case, the movement means of this opening movement as long as the resistance of the coil springs 34 counter until the end caps 32a, 32b in turn pass through the dead center in the amount of the connecting line v between the pivot axes 20a, 20b. Thereafter, the springs 34 press the end caps 32a, 32b automatically further upward in the direction of the open position and hold the clamping bracket 18a, 18b finally in the open position. The bearing pins 35a, 35b detach from the engagement with the bearing holes 68 and the ski boot 60 can finally be pulled out of the ski binding become.

  4. Touring ski binding (10) according to any of the preceding claims, characterised in that in the second pivot position, the ski boot (60) is pivoted forwards about an angle (W) of from approximately 70° to approximately 110°, preferably from approximately 90°, relative to a ski plane (E).
  5. Touring ski binding (10) according to any of the preceding claims, characterised in that the locking actuation element (58) is arranged so as to be contacted and actuated by a front boot-tip portion (62) of the ski boot (60) upon the pivoting movement of the ski boot (60) towards the second pivot position.
  6. Touring ski binding (10) according to any of the preceding claims, characterised in that the locking mechanism (48, 58) further comprises a locking operation element (52) which can be manually operated by a user so the locking mechanism (48, 58) locks the bearing arrangement (18a, 18b, 35a, 35b), the locking operation element (52) and the locking actuation element (58) being either interconnected or coupled so as to move together.
  7. Touring ski binding (10) according to any of the preceding claims, characterised in that the bearing arrangement (18a, 18b, 35a, 35b) comprises a release mechanism (18a, 18b, 34) which, upon action of a force which exceeds a predetermined release force, is triggered in order to release the ski boot (60) from the bearing arrangement (18a, 18b, 35a, 35b), the locking mechanism (48, 58) blocking the release mechanism (18a, 18b, 34).
  8. Touring ski binding (10) according to any of the preceding claims, characterised in that the bearing arrangement comprises two lateral bearing elements (35a, 35b) which are arranged on the ski transverse axis (Q) and equipped to engage with lateral counter bearing elements (68) of the ski boot (60) in order to hold the ski boot (60) so as to be pivotable about the ski transverse axis (Q), the bearing elements (35a, 35b) being movable between a closed position, in which the bearing elements (35a, 35b) are at a spacing which is designed for engagement with the counter bearing elements (68), and an open position, in which the bearing elements (35a, 35b) are at a spacing which is greater than in the closed position, so that the ski boot (60) can be introduced between the bearing elements (35a, 35b) or removed from the touring ski binding (10).
  9. Touring ski binding (10) according to claim 8, characterised in that the touring ski binding (10) further comprises a binding actuation element (37) for actuating the touring ski binding (10), the binding actuation element (37) and the bearing elements (35a, 35b) being coupled so as to move together, and in that the locking mechanism (48, 58) blocks movement of the binding actuation portion (37) from the closed position into the open position.
  10. Touring ski binding (10) according to claim 8 and claim 9, further characterised by two clamping angles (18a, 18b), each of which is held so as to be pivotable about an axis (20a, 20b) parallel to the ski central axis (M), each clamping angle (18a, 18b) comprising a first branch (22a, 22b), on the distal end of which one of the bearing elements (35a, 35b) is arranged, and a second branch (26a, 26b), the distal end of which point towards the respective other clamping angle (18a, 18b), the binding actuation element (37) being a two-armed binding actuation lever which is mounted pivotally about an axis (36) which is substantially parallel to a ski plane (E), the first arm (38) of which lever acts upon the two distal ends of the second branch (26a, 26b) of the clamping angle (18a, 18b), and on the second arm (48) of which lever, an actuation portion (48) for manual actuation is arranged.
  11. Touring ski binding (10) according to claim 10, characterised in that the locking mechanism (48, 58) comprises a locking member (54) which is installed pivotally on the second arm (46) of the binding actuation lever (37), and in that the locking actuation element (58) is coupled with or connected to the locking member (54) in such a way that a movement of the locking actuation element (58), when pivoting the ski boot (60) into the second pivot position, pivots the locking member (54) into a locking position, in which the locking member (54) is arranged between the second arm (46) of the binding actuation lever (37) and the ski (16) so that a pivoting movement of the binding actuation lever (37) from the closed position into the open position is blocked.
  12. Touring ski binding (10) according to claim 11, further characterised by a cam mechanism (72, 54), which converts a progressive pivoting movement of the locking member (54) towards a locking position into a progressive pivoting movement of the binding actuation lever (37) in order to progressively increase a tensile force acting between the bearing elements (35a, 35b), with which tensile force the ski boot (60) is held on the bearing arrangement (18a, 18b, 35a, 35b).
