Description

Die Erfindung bezieht sich auf eine Sicherheitsskibindung mit einem bei Überschreiten einer bestimmten, auf die Bindung einwirkenden Kraft auslösbaren Fersenbacken, der einen im wesentlichen skifesten Teil und einem mit diesem schwenkbar verbundenen Sohlenniederhalter aufweist, wobei der Sohlenniederhalter in seiner den Schuh haltenden Stellung mit dem skifesten Teil mittels einer Raste-Rastbahnanordnung verriegelbar ist, die durch eine im wesentlichen in Skilängsrichtung wirkende Feder belastet ist, wobei ein Teil der Raste-Rastbahnanordnung am Sohleniederhalter und deren anderer Teil am skifesten Teil angeordnet sind, und die Rastbahn in der verriegelten Stellung des Sohlenniederhalters schräg gegen die Skioberfläche geneigt verläuft und die beiden Teile der Raste-Rastbahnanordnung einander übergreifen, und die schwenkbare Verbindung des Sohlenniederhalters mit dem skifesten Teil über eine Lasche erfolgt, die von zwei parallel zur Skioberseite und senkrecht zur Skilängsachse angeordneten Achsen durchsetzt ist, von denen die eine Achse im skifesten Teil und die andere Achse im Sohlenniederhalter gehalten ist.The invention relates to a safety ski binding with a heel shoe which can be triggered when a certain force acting on the binding is exceeded, which has an essentially ski-fixed part and a sole hold-down device pivotally connected to the latter, the sole hold-down device in its position holding the shoe with the ski-fixed part can be locked by means of a detent-latching track arrangement which is loaded by a spring which acts essentially in the longitudinal direction of the ski, part of the latching-latching track arrangement being arranged on the sole retainer and the other part of which is arranged on the ski-fixed part, and the latching track obliquely in the locked position of the sole retainer the ski surface runs at an incline and the two parts of the detent-locking track arrangement overlap one another, and the pivotable connection of the sole hold-down device to the ski-fixed part takes place via a strap which is parallel to the top of the ski and perpendicular to the longitudinal axis of the ski arranged axes is penetrated, of which one axis is held in the ski-fixed part and the other axis in the sole hold-down.

Durch die DE-A-17 03 638 wurde ein solcher Fersenbacken vorgeschlagen. Bei diesem laufen die Laschen im wesentlichen parallel zur Skioberfläche und überdies besteht neben der Verbindung des Sohlenniederhalters mit dem im wesentlichen skifesten Teil des Backens über die Laschen noch eine weitere formschlüssige Verbindung zwischen diesen Teilen über eine in einem Schlitz des skifesten Teiles geführte Achse, die mit dem Sohlenniederhalter fest verbunden ist.Such a heel shoe has been proposed by DE-A-17 03 638. In this case, the tabs run essentially parallel to the ski surface and, in addition to the connection of the sole hold-down device to the essentially ski-fixed part of the jaw via the tabs, there is also another form-fitting connection between these parts via an axis guided in a slot in the ski-fixed part, which with the sole hold-down is firmly connected.

Bei dieser bekannten Lösung ist daher eine Verschiebung des Sohlenniederhalters in Längsrichtung des Skis unmöglich. Dadurch ändern sich aber auch die Auslösewerte der Bindung bei jeder Schneeauflage an der Sohle des von dieser gehaltenen Skischuhs oder bei einer Längenänderung dessen Sohle, wodurch sich ein entsprechendes Sicherheitsproblem ergibt.In this known solution, it is therefore impossible to move the sole retainer in the longitudinal direction of the ski. As a result, however, the release values of the binding also change with each snow covering on the sole of the ski boot held by the latter, or in the event of a change in the length of the sole thereof, thereby there is a corresponding security problem.

Weiters wurde durch die EP-A1-0072 904 ein Fersenbacken bekannt, bei der ein Sohlenniederhalter an dem Auslösehebel anliegt, wobei die beiden aneinander anliegenden Flächen dieser Teile konkave bzw. konvexe Ausformungen aufweisen, die einander entsprechen. Dabei ist der Auslösehebel um eine im Backengehäuse gehaltene skifeste Achse schwenkbar und mittels einer Raste-Rastbahnanordnung in seiner Abfahrtsstellung verrastbar. Die Verbindung des Sohlenniederhalters mit dem Auslösehebel erfolgt mittels einer Laschenanordnung, die von zwei in je einem dieser Teile angeordneten, zueinander parallel verlaufenden Achsen durchsetzt ist. Dabei durchsetzt die gleichzeitig als Schwenkachse für den Auslösehebel dienende Achse ein Langloch der Laschenanordnung, die in der Abfahrtsstellung des Backens stirbnseitig von einer in einer Bohrung des Auslösehebels gehaltenen Feder belastet ist, die in Längsrichtung des Langloches der Laschenanordnung im Sinne einer Trennung des Sohlenniederhalters von der Anlagefläche an dem Auslösehebel belastet.Furthermore, a heel shoe was known from EP-A1-0072 904, in which a sole hold-down abuts the release lever, the two abutting surfaces of these parts having concave or convex shapes which correspond to one another. The release lever can be pivoted about a ski-fixed axis held in the jaw housing and can be locked in its downward position by means of a detent-locking track arrangement. The sole hold-down device is connected to the release lever by means of a tab arrangement which is penetrated by two axes which are arranged in one of these parts and run parallel to one another. The axis that also serves as a pivot axis for the release lever penetrates an elongated hole in the tab arrangement which, in the downward position of the jaw, is loaded on the end face by a spring held in a bore in the release lever, which in the longitudinal direction of the elongated hole in the tab arrangement in the sense of separating the sole hold-down device from the Contact surface on the release lever loaded.

Der Nachteil diser Lösung liegt in der komplizierten Form der Anlageflächen des Auslösehebels und des Sohlenniederhalters. Außerdem kommt es bei dieser Lösung bereits bei geringen Schneeauflagen auf dem zu haltenden Skischuh oder Teilen des Backens zu beträchtlichen Verspannungen, die auch zu Änderungen der Auslösewerte des Backens führen können, da eben die Längskräfte über den Auslösehebel, bzw. die diesen mit dem skifesten Teil des Backens verbindende Achse in diesen eingeleitet werden und daher kein Längenausgleich vorhanden ist.The disadvantage of this solution lies in the complicated shape of the contact surfaces of the release lever and the sole hold-down. In addition, with this solution, there is considerable tension even on the snow shoe to be held or parts of the cheek, which can also lead to changes in the release values of the cheek, since the longitudinal forces are exerted by the release lever or by the part attached to the ski of the jaw connecting axis are introduced into this and therefore there is no length compensation.

Diese Nachteile treten auch bei dem aus der DE-A-24 32 646 bekannten Backen auf, bei dem der Sohlenniederhalter über eine Achse mit einem skifesten Teil des Backens und über eine Lasche mit einem Schubglied verbunden ist, das seinerseits über zwei Laschen mit dem skifesten Teil des Backens verbunden und von einer Feder belastet ist. Bei dieser Lösung ist zwar eine geringe Verschiebbarkeit des Sohlenniederhalters in Skilängsrichtung gegeben, da der Sohlenniederhalter ein Langloch aufweist, das von der diesen mit dem skifesten Teil des Backens verbindenden Achse durchsetzt ist, doch ist dies nur entgegen der Kraft der Auslösefeder möglich, wodurch sich aber eine entsprechend direkte Beeinflussung der Auslösewerte des Backens ergibt.These disadvantages also occur with the jaws known from DE-A-24 32 646, in which the sole hold-down device is connected via an axis to a part of the jaw which is fixed to the ski and via a plate with a pushing element which in turn is connected to the fixed part via two plates Part of the jaw is connected and loaded by a spring. With this solution, there is little displacement of the sole hold-down in the longitudinal direction of the ski given that the sole hold-down has an elongated hole which is penetrated by the axis connecting it to the ski-fixed part of the jaw, but this is only possible against the force of the release spring, but this has a correspondingly direct influence on the release values of the jaw.

Weiters wurde durch die DE-A-31 07 230 eine Sicherheitsskibindung mit einem Sohlenniederhalter bekannt, der einerseits über eine Schwenkachse mit einem skifesten Teil direkt und außerdem über ein Kniehebelsystem verbunden ist. Dabei ist die Verbindungsachse der beiden, das Kniehebelsystem bildenden Hebel mittels eines an dem skifesten Teil schwenkbar gehaltenen Sperrhebel in einer der verriegelten Stellung des Sohlenniederhalters entsprechenden Lage haltbar.Furthermore, from DE-A-31 07 230 a safety ski binding with a sole hold-down device was known, which is connected on the one hand directly to a ski-fixed part via a pivot axis and also via a toggle lever system. The connecting axis of the two levers forming the toggle lever system can be held in a position corresponding to the locked position of the sole hold-down device by means of a locking lever pivotally held on the ski-fixed part.

Auch bei dieser Lösung ergibt sich der Nachteil, daß es bei einer Längenänderung der Sohle des zu haltenden Skischuhs zu einer erheblichen Beeinflussung der Auslösekraft kommt und sich daher die bereits erwähnten sicherheitstechnischen Problem ergeben.This solution also has the disadvantage that a change in the length of the sole of the ski boot to be held has a considerable influence on the triggering force and therefore the safety-related problems already mentioned arise.

Durch die WO 88/01191 Veröffentlichungsdatum : 25.02.88 wurde eine Sicherheitsskibindung mit einem Fersenbacken bekannt, bei dem der Sohlenniederhalter mit einem skifesten Teil über eine Schwenkachse miteinander verbunden sind. Dabei weist der Sohlenniederhalter eine Rastbahn auf, die von einer an dem skifesten Teil schwenkbar gehaltenen Raste übergreifbar ist, die mittels einer an einem auslösbaren Widerlager abgestützten Feder gegen die den Sohlenniederhalter übergreifenden Lage vorgespannt ist.From WO 88/01191 publication date: February 25, 2008, a safety ski binding with a heel shoe was known, in which the sole hold-down device is connected to one another with a ski-fixed part via a pivot axis. The sole hold-down device has a latching path which can be overlapped by a detent pivotally held on the ski-fixed part, which is biased by means of a spring supported on a releasable abutment against the position overlapping the sole hold-down device.

Auch bei dieser bekannten Lösung ist eine Längenänderung der Sohle des zu haltenden Skischuhs mit einer erheblichen Änderung der Auslösewerte der Bindung verbunden.In this known solution, too, a change in the length of the sole of the ski boot to be held is associated with a considerable change in the release values of the binding.

Weiters wurde durch die WO 84/03050 eine Sicherheitskibindung mit einem Fersenbacken bekannt, bei dem ein Sohlenniederhalter mit einem skifesten Teil über einen Kniehebel verbunden ist. Dabei ist noch eine weitere Verbindung dieser Teile über einen an dem skifesten Teil schwenkbar gelagerten Hebel vorgesehen, der an dem Sohlenniederhalter angelenkt ist und sich mit seinem zweiten Hebelarm an dem skifesten Teil abstützt. Die Verriegelung des Sohlenniederhalters in dessen Arbeitsstellung erfolgt dabei mittels eines federbelasteten Sperrhebels, der die Bewegung der Verbindungsachse der beiden Teile des Kniehebels bei auf die Bindung einwirkenden Kräften verhindert, solange diese nur eine ungefährliche Größe aufweisen.Furthermore, a safety ski binding with a heel shoe was known from WO 84/03050, in which a sole hold-down device is connected to a ski-fixed part via a toggle lever. There is a further connection of these parts via one on the ski-fixed part pivotally mounted lever is provided, which is articulated on the sole hold-down and is supported with its second lever arm on the ski-fixed part. The sole hold-down device is locked in its working position by means of a spring-loaded locking lever, which prevents the movement of the connecting axis of the two parts of the toggle lever under forces acting on the binding, as long as these are only of a safe size.

Allerdings ergibt sich auch bei dieser Bindung der Nachteil, daß eine Längenänderung der Sohle des zu haltenden Skischuhs einen sehr erheblichen Einfluß auf die Auslösekraft der Bindung ausübt.However, this binding also has the disadvantage that a change in the length of the sole of the ski boot to be held exerts a very considerable influence on the release force of the binding.

Ziel der Erfindung ist es, diese Nachteile zu vermeiden und einen Fersenbacken der eingangs erwähnten Art vorzuschlagen, der sich durch einen einfachen Aufbau auszeichnet und bei dem ein Längenausgleich sowie ein Ausgleich für eine Schneeauflage an der Sohle ohne wesentliche Änderung der Auslösewerte möglich ist.The aim of the invention is to avoid these disadvantages and to propose a heel shoe of the type mentioned at the outset, which is distinguished by a simple structure and in which length compensation and compensation for a snow covering on the sole is possible without a significant change in the trigger values.

Erfindungsgemäß wird dies dadurch erreicht, daß die Lasche in der verriegelten Stellung des Sohlenniederhalters im wesentlichen senkrecht zur Skioberseite verläuft, und der Sohlenniederhalter gegen die Kraft der die Raste-Rastbahnanordnung belastenden Feder unter Verschwenkung der Lasche um die am skifesten Teil gehaltene Achse in Skilängsrichtung verschiebbar am skifesten Teil des Backens gehalten ist.According to the invention this is achieved in that the tab extends substantially perpendicular to the top of the ski in the locked position of the sole hold-down device, and the sole hold-down device can be displaced in the longitudinal direction of the ski in the longitudinal direction of the ski against the force of the spring loading the latching latching track arrangement by pivoting the tab part of the jaw fixed to the ski.

Durch diese Maßnahmen ist sichergestellt, daß der Sohlenniederhalter entgegen der Kraft der Feder in Skilängsrichtung verschoben werden kann, wodurch ein entsprechender Ausgleich bei Längenänderungen der Skischuhsohle möglich ist und sich daher, wenn überhaupt, nur geringste Änderungen der Auslösewerte der Bindung ergeben. Dabei wird dieser Weg von der Laschenanordnung aufgenommen. Da lediglich eine gelenkige Verbindung des Sohlenniederhalters mit dem skifesten Teil, und zwar jene über die eine Achse der Laschenanordnung, vorgesehen ist, ergibt sich bei einer Verschiebung des Sohlenniederhalters in Längsrichtung gegenüber dem skifesten Teil praktisch keine Änderung der Anpressung des Schuhs an den Ski. Die eingestellten Auslösewerte bleiben daher trotz der dabei entstehenden Komprimierung der Spannfeder weitgehend konstant.These measures ensure that the sole hold-down device can be displaced in the longitudinal direction of the ski against the force of the spring, so that a corresponding compensation for changes in the length of the ski shoe sole is possible and therefore, if at all, there are only slight changes in the release values of the binding. This way is taken up by the tab arrangement. Since there is only an articulated connection of the sole hold-down device to the ski-fixed part, specifically that via one axis of the strap arrangement, this results with a shift of the sole hold-down device in the longitudinal direction with respect to the ski-fixed part there is practically no change in the contact pressure of the boot on the ski. The set trigger values therefore remain largely constant despite the compression of the tension spring.

Aus Gründen einer besonders einfachen Konstruktion ist es vorteilhaft, wenn die Laschenanordnung an dem vom zweiten Backen abgekehrten Ende des Sohlenniederhalters angeordnet ist. Durch die in der Betriebsstellung des Backens im wesentlichen senkrecht zum Ski verlaufenden Stellung der Laschen ergibt sich ein ausreichend großer Weg für einen Längenausgleich der Sohle, auch wenn die Länge der Laschen klein gehalten ist. Dieser Längenausgleich ist insbesondere bei Sohlen aus einem hygroskopischen Material von Bedeutung.For reasons of a particularly simple construction, it is advantageous if the tab arrangement is arranged on the end of the sole holding-down device facing away from the second jaw. The position of the straps, which is essentially perpendicular to the ski in the operating position of the jaw, results in a sufficiently large path for a length compensation of the sole, even if the length of the straps is kept small. This length compensation is particularly important for soles made from a hygroscopic material.

Bei einem erfindungsgemäßen Fersenbacken, bei dem die Rastbahn an einem schwenkbar an dem, im wesentlichen skifesten Teil schwenkbar gehaltenen Arm angeordnet ist und die Raste durch einen an dem Sohleniederhalter gehaltenen Ansatz gebildet ist, wobei der Arm durch die Feder abgestützt ist, die ihrerseits an einem Widerlager abgestützt ist, kann nach einem weiteren Merkmal der Erfindung vorgesehen sein, daß der Ansatz eine im Querschnitt kreisrunde Rolle drehbar hält und zwischen den im wesentlichen skifesten Teil des Backens und dem Ski ein Kraftaufnehmer vorgesehen ist, der über eine elektronische Auswerteschaltung mit einer Steuervorrichtung für das Widerlager verbunden ist.In a heel shoe according to the invention, in which the latching path is arranged on an arm pivotably held on the substantially ski-fixed part and the latch is formed by an attachment held on the sole holding-down device, the arm being supported by the spring, which in turn is supported on one Abutment is supported, can be provided according to a further feature of the invention that the approach rotatably holds a roller with a circular cross-section and a force transducer is provided between the substantially ski-fixed part of the jaw and the ski, which has an electronic evaluation circuit with a control device for the abutment is connected.

Dadurch ergibt sich eine sehr einfache Konstruktion, bei der sich auch sehr kurze Verbindungsleitungen vom Kraftaufnehmer zur Auswerteschaltung ergeben, wobei diese sehr leicht gut gegen Beschädigungen geschützt geführt werden können. Weiters wird auch erreicht, daß auch bei einem nach einer Auslösung hochgeschwenkten Sohlenniederhalter die dadurch entstehende Öffnung des Backens durch den die Rastbahn aufweisenden Arm weitgehend abgedeckt wird, so daß im Falle eines Sturzes kaum Schnee in das Innere des Backens eindringen kann, wodurch Störungen in der Funktion des Backens weitgehend vermieden werden.This results in a very simple construction, in which there are also very short connecting lines from the force transducer to the evaluation circuit, these being very easy to protect against damage. Furthermore, it is also achieved that, even when the sole hold-down is pivoted up after a release, the opening of the jaw resulting therefrom is largely covered by the arm having the latching track, so that in the event of a fall hardly any snow can penetrate into the interior of the jaw, thereby causing malfunctions largely avoided in the function of baking.

Weiters kann vorgesehen sein, daß zwischen dem die Rastbahn tragenden Hebel und einem an dem im wesentlichen skifesten Teil des Backens schwenkbar gehaltenen Stützarm eine die Feder führende, aus zwei teleskopartig ineinanderschiebbaren Teilen gebildete Koppelstange vorgesehen ist, die mit ihren beiden freien Enden gelenkig mit diesen Armen verbunden ist, wobei der Stützarm Teil des die Feder abstützenden Widerlagers ist und im betriebsbereiten Zustand des Backens von einem, den zweiten Teil des Widerlagers bildenden, von der Steuervorrichtung betätigbaren und von dieser schwenkbar gehaltenen Rastarm abgestützt ist, wobei die Achse der Koppelstange zwischen den Drehachsen dieser beiden Arme, jedoch knapp neben der Drehachse des Stützarmes verläuft und die beiden Arme im betriebsbereiten Zustand des Backens einen Winkel einschließen, dessen Scheitel dem die Rastbahn tragenden Arm zugekehrt ist.Furthermore, it can be provided that between the lever carrying the latching path and a support arm which is pivotally held on the essentially ski-fixed part of the jaw, a spring-guiding coupling rod formed from two telescopically telescoping parts is provided, which with its two free ends is articulated with these arms is connected, wherein the support arm is part of the spring-supporting abutment and is supported in the operational state of the baking by a, the second part of the abutment forming, operated by the control device and pivotally held by this locking arm, the axis of the coupling rod between the axes of rotation of these two arms, but runs just next to the axis of rotation of the support arm and the two arms enclose an angle in the ready-to-use state of the jaw, the apex of which is turned towards the arm carrying the latching path.

Durch diese Maßnahmen ergibt sich der Vorteil, daß der Rasthebel bereits mit relativ kleinen Kräften aus seiner den Stützarm abstützenden Lage ausgelenkt werden kann, wodurch dieser und damit auch die Spannfeder seine bzw. ihre Abstützung verliert und damit die Verrastung des Sohlenniederhalters mit dem im wesentlichen skifesten Teil gelöst wird. Dabei ist auch die Abstützung der Spannfeder mittels der Koppelstange wesentlich, wodurch eine Biegebeanspruchung der Feder, welche zu einer ungleichmäßigen Belastung der Feder und damit zu deren vorzeitiger Ermüdung führt, sicher vermieden wird.These measures have the advantage that the locking lever can be deflected from its position supporting the support arm with relatively small forces, whereby this and thus the tension spring loses its support and thus the locking of the sole hold-down with the essentially ski-fixed Part is solved. The support of the tension spring by means of the coupling rod is also essential, whereby a bending stress on the spring, which leads to an uneven loading of the spring and thus to its premature fatigue, is reliably avoided.

Der erfindungsgemäße Fersenbacken eignet sich grundsätzlich sowohl für eine Anwendung in Verbindung mit einem auslösbaren Vorderbacken, wie auch in Verbindung mit einem nicht auslösbaren Vorderbacken, wie er häufig für Tourenbindungen verwendet wird. Aus Gründen einer hohen Auslösesicherheit ist es jedoch bei einem Einsatz eines erfindungsgemäßen Fersenbackens in Verbindung mit einem nicht auslösbaren Vorderbacken zweckmäßig, den ersteren in Verbindung mit einer Bindungsplatte einzusetzen.The heel jaw according to the invention is fundamentally suitable both for an application in connection with a releasable front jaw, as well as in connection with a non-releasable front jaw, as is often used for touring bindings. For reasons of high release security, however, when using a heel shoe according to the invention in connection with a non-releasable front shoe, it is expedient to use the former in conjunction with a binding plate.

Erfindungsgemäß kann weiters vorgesehen sein, daß der im betriebsbereiten Zustand des Fersenbackens skifest gehaltene Teil des Backens eine Sohllenplatte ist, bzw. an einer solchen angeordnet ist, die um einen im Bereich des Durchstoßpunktes der Tibia mit der Skioberseite angeordneten Zapfen, sowie um eine im vorderen Bereich der Sohlenplatte angeordnete, quer zur Skilängsachse und im wesentlichen parallel zur Skioberfläche verlaufende Achse drehbar angeordnet und über einen von dem vertikalen Zapfen beabstandeten, in ein skifestes Widerlager eingreifenden Zapfen, der vorzugsweise über den Kraftaufnehmer mit der Sohlenplatte oder mit dem skifesten gehaltenen Teil des Backens verbunden ist, gegen eine Verdrehung gesichert gehalten ist.According to the invention, it can further be provided that the part of the cheek held ski-tight in the operational state of the heel cheek is a sole plate, or is arranged on such a plate, which is arranged around a pin arranged in the region of the penetration point of the tibia with the ski top, as well as around one in the front Area of the sole plate arranged, rotatable transversely to the longitudinal axis of the ski and essentially parallel to the ski surface, and arranged via a pin spaced apart from the vertical pin and engaging in a ski-like abutment, preferably via the force transducer with the sole plate or with the ski-fixed part of the cheek is connected, is held secured against rotation.

Diese Ausführungsform eignet sich besonders für Fersenbacken mit einem elektronisch gesteuerten Auslöseglied, da damit die auf die Bindung einwirkenden Kräfte auf sehr kleinen Wegen erfaßt werden können, wobei die geringe, aufgrund der Elastizität der einzelnen Bauteile, aber auch deren Befestigung auf dem Ski gegebene Verschiebbarkeit der Platte gegenüber dem Ski ausreicht, um die einwirkenden Kräfte erfassen zu können.This embodiment is particularly suitable for heel cheeks with an electronically controlled release member, since it allows the forces acting on the binding to be detected in very small ways, the small, due to the elasticity of the individual components, but also their attachment to the ski given the displaceability The plate opposite the ski is sufficient to be able to record the acting forces.

In diesem Zusammenhang kann weiters vorgesehen sein, daß der Kraftaufnehmer in einem dicht geschlossenen Gehäuse angeordnet ist, in dem eine die Ausgangssignale des Kraftaufnehmers verarbeitete elektronische Auswerteschaltung samt einem Stellglied der Steuervorrichtung, das den Rastarm steuert, eingeschlossen sind, wodurch die sich sehr kurze Leitungswege zur Übertragung der Ausgangssignale des Meßwertwandlers und eine geschützte Anordnung der sehr empfindlichen elektronischen Bauteile ergeben.In this context, it can further be provided that the force transducer is arranged in a tightly closed housing, in which an electronic evaluation circuit, processed the output signals of the force transducer, together with an actuator of the control device that controls the latching arm, are included, as a result of which the very short conduction paths Transmission of the output signals of the transducer and a protected arrangement of the very sensitive electronic components result.

Die in Fig. 1 dargestellte Bindung ist als eine auf der Oberseite 10a eines Ski 10 angeordnete Plattenbindung ausgebildet, wobei die Bindungsplatte 1 um einen ballig ausgeführten Zapfen 40 drehbar ist, der auf dem Ski 10 im Bereich des Durchstoßpunktes der Achse der Tibia des Skiläufers mit der Skiebene befestigt ist und eine Drehung der Bindungsplatte 1 in der Ebene des Skis 10 ermöglicht. Im vorderen Bereich der Bindungsplatte 1 weist diese eine Achse 41 auf, die einen in Skilängsrichtung verlaufenden Schlitz 42 einer skifest angeordneten Halterung 45 durchsetzt, die in eine, an der Unterseite der Bindungsplatte 1 ausgebildete Ausnehmung 1' mit allseitig großem Spiel hineinragt, wodurch eine beschränkte Verdrehung der Bindungsplatte 1 um den Zapfen 40 und ein Hochschwenken derselben um die Achse 41 möglich ist.The binding shown in FIG. 1 is designed as a plate binding arranged on the upper side 10a of a ski 10, the binding plate 1 being rotatable about a spherical pin 40 which is on the ski 10 in the region of the point of intersection of the axis of the skier's tibia the ski plane is fastened and enables the binding plate 1 to rotate in the plane of the ski 10. In the front area of the binding plate 1, this has an axis 41, which passes through a slot 42 of a ski-mounted holder 45 which runs in the longitudinal direction of the ski and which protrudes into a recess 1 'formed on the underside of the binding plate 1 with great play on all sides, as a result of which limited Rotation of the binding plate 1 about the pin 40 and pivoting the same about the axis 41 is possible.

Weiters ist im vorderen Bereich der Bindungsplatte 1 ein starrer, nicht auslösbarer Zehenbacken 43 in Längsrichtung der Bindungsplatte einstell- und feststellbar gehalten.Furthermore, in the front area of the binding plate 1, a rigid, non-releasable toe jaw 43 is held in the longitudinal direction of the binding plate so that it can be adjusted and locked.

Der im hinteren Bereich der Bindungsplatte angeordnete auslösbare Fersenbacken 5 ist mit der Bindungsplatte 1 verbunden, wobei dessen Sohlenniederhalter 17 um die Achse 9 hochschwenkbar ist. Weiters ist die Bindungsplatte 1 in ihrem hinteren Bereich mit einem Schaltbaustein 44 fest verbunden, der über Kraftaufnehmer 4 und ein Meßelement 3, das ein kugelkopfförmiges Ende aufweist, in einem skifesten Widerlager 2 abgestützt ist.The releasable heel shoe 5 arranged in the rear region of the binding plate is connected to the binding plate 1, the sole hold-down device 17 of which can be swiveled up about the axis 9. Furthermore, the binding plate 1 is firmly connected in its rear area to a switching module 44 which is supported in a ski-mounted abutment 2 via force transducers 4 and a measuring element 3 which has a spherical head-shaped end.

Dadurch ist die Bindungsplatte 1 in ihrer Lage im wesentlichen fixiert, wobei aber eine Bewegung der Bindungsplatte 1 im Ausmaß der Meßwege der Kraftaufnehmer 4 möglich ist, die aufgrund der festen Drehpunkte der Bindungsplatte 1 um den Zapfen 40 und die Achse 41 die Erfassung der auf die Bindungsplatte 1 einwirkenden Momente ±Mz und ±My ermöglichen.As a result, the binding plate 1 is essentially in its position fixed, but a movement of the binding plate 1 in the extent of the measuring paths of the force transducers 4 is possible, which, due to the fixed pivot points of the binding plate 1 around the pin 40 and the axis 41, enables the detection of the moments ± Mz and ± My acting on the binding plate 1 .

Beim Fersenbacken 5 ist für dessen Sohlenniederhalter 17 eine übliche Öffnungsfeder 23 vorgesehen, die an der Bindungsplatte 1 und dem Sohlenniederhalter 17 abgestützt ist und diesen in Richtung seiner in der Fig. 5 dargestellten, hochgeschwenkten Endstellung vorspannt.In the heel shoe 5, a conventional opening spring 23 is provided for the sole hold-down device 17, which is supported on the binding plate 1 and the sole hold-down device 17 and prestresses it in the direction of its swiveled-up end position shown in FIG. 5.

Der im wesentlichen haubenförmige Sohlenniederhalter 17 weist eine gegen sein Inneres vorstehende Nase 17a, auf der eine Rastrolle 16 drehbar gehalten ist, auf, die in der verriegelten Stellung der Bindung von einem eine Rastbahn 31 aufweisenden Arm 18 übergriffen ist. Dieser Arm 18 ist an einer Drehachse 28 schwenkbar gehalten, die ihrerseits am bindungsplattenfesten Teil des Fersenbackens 5 fixiert ist. An dem Arm 18 ist eine teleskopartig zusammenschiebbare Koppelstange 20 angelenkt, die den Arm 18 mit einem weiteren, um eine mit der Bindungsplatte 1 starr verbundene Drehachse 29 schwenkbar gehaltenen Stützhebel 21 verbindet, wobei die Koppelstange 20 in an diesen beiden Teilen angelenkten Abstützungen 46 einer Spannfeder 19 mit einem größeren Spiel und in ihrer Längsrichtung verschiebbar gehalten ist.The substantially hood-shaped sole hold-down device 17 has a nose 17a projecting against its interior, on which a locking roller 16 is rotatably held, which in the locked position of the binding is overlapped by an arm 18 having a locking path 31. This arm 18 is pivotally held on an axis of rotation 28, which in turn is fixed to the part of the heel 5 fixed to the binding plate. On the arm 18 is a telescopically collapsible coupling rod 20 is articulated, which connects the arm 18 with a further, about a rotationally rigidly connected to the binding plate 1 axis of rotation 29 support lever 21, the coupling rod 20 in hinged to these two parts supports 46 of a tension spring 19 is held with a larger game and displaceable in its longitudinal direction.

Zwischen den über die Koppelstange 20 miteinander verbundenen Teilen wirkt die Spannfeder 19, die die beiden Teile auseinander drängt. Damit wird der Arm 18 bei abgestütztem Stützhebel 21 gegen die Rastrolle 16 gepreßt, wodurch der Sohlenniederhalter 17 an einem Hochschwenken gehindert ist. Der Arm 18 mit der Rastbahn 31 und die an der Nase 17a des Sohlenniederhalters 17 gelagerte Rastrolle 16 bilden Bauteile einer Raste-Rastbahnanordnung 16, 17a; 18, 31.The tension spring 19, which urges the two parts apart, acts between the parts connected to one another via the coupling rod 20. Thus, the arm 18 is pressed against the locking roller 16 with the support lever 21 supported, whereby the sole hold-down device 17 is prevented from swinging up. The arm 18 with the latching track 31 and the latching roller 16 mounted on the nose 17a of the sole holding-down device 17 form components of a latching latching track arrangement 16, 17a; 18, 31.

In dem Fersenbacken 5 ist ein Handauslösekopf 15 über eine Achse 30 schwenkbar gelagert, wobei dieser Kopf 15 mittels einer Feder 30' gegen seine inaktive Lage vorgespannt ist. Beim Drücken des Auslösekopfes 15 schwenkt dieser im Uhrzeigersinn bzw. entgegen der Kraft der Feder 30' und drückt auf einen Auslösestift 14, der in einer Durchführung des Gehäuses 6 des Schaltbausteines 44, der einen Auslösemechanismus umschließt, gehalten und mittels einer nicht sichtbaren Feder gegen seine, in den Figuren dargestellte, inaktive Lage vorgespannt ist. Dieser Auslösestift 14 ist z.B. mittels eines O-Ringes gegen das Gehäuse 6 abgedichtet, doch ist es auch möglich, den Auslösestift mittels einer Membrane abzudichten, die über das freie Ende des Auslösestiftes gespannt, oder als Teil des Gehäuses ausgeführt ist und an der der Auslösekopf 15 zur Anlage bringbar ist.In the heel shoe 5, a hand release head 15 is pivotally mounted about an axis 30, this head 15 by means of a spring 30 'is biased against its inactive position. When the trigger head 15 is pressed, it pivots clockwise or counter to the force of the spring 30 'and presses on a trigger pin 14 which is held in a passage of the housing 6 of the switching component 44, which encloses a trigger mechanism, and against it by means of a non-visible spring , inactive position shown in the figures is biased. This trigger pin 14 is sealed, for example, by means of an O-ring against the housing 6, but it is also possible to seal the trigger pin by means of a membrane which is stretched over the free end of the trigger pin, or is designed as part of the housing and on which the trigger head 15 can be brought to the plant.

Das Meßelement 3 ist im skifesten Widerlager 2 über seinen kugelgelenkförmigen Kopf abgestützt. Dieses Meßelement 3 weist Kraftaufnehmer 4 auf, die die auf die Bindungsplatte 1 um deren Drehachsen auftretenden Momente ±My und ±Mz erfassen und in elektrische Signale umwandeln. Diese Kraftaufnehmer 4, die beliebig z.B. als piezoelektrische Wandler oder als Dehnungsmeßstreifen ausgebildet sein können, sind mit dem Gehäuse 6 des Schaltbausteines 44 verbunden, in dem eine Batterie, eine Auswerteschaltung, sowie ein elektromechanisches Auslöseelement, z.B. ein Elektromagnet, und Teile eines mechanischen Verriegelungssystems der Bindung untergebracht sind. Bezüglich des Auslöseelementes ist zu bemerken, daß dieses auch durch andere Bauteile, wie z.B. einem piezoelektrischen Wandler, gebildet sein kann. Der Schaltbaustein 44 selbst ist nicht Gegenstand dieser Erfindung und kann z.B. gemäß der Anmeldung 87905444.3 - PCT/EP 8700443 (nachveröffentlicht als WO 88/01191) ausgebildet sein.The measuring element 3 is supported in the ski-fixed abutment 2 via its ball-shaped head. This measuring element 3 has force transducers 4, which detect the moments ± My and ± Mz occurring on the binding plate 1 about their axes of rotation and convert them into electrical signals. These force transducers 4, which e.g. can be designed as piezoelectric transducers or as strain gauges, are connected to the housing 6 of the switching component 44, in which a battery, an evaluation circuit and an electromechanical trigger element, e.g. an electromagnet, and parts of a mechanical locking system of the binding are housed. Regarding the trigger element, it should be noted that this can also be caused by other components, e.g. a piezoelectric transducer can be formed. The switching module 44 itself is not the subject of this invention and can e.g. according to the application 87905444.3 - PCT / EP 8700443 (republished as WO 88/01191).

Der Auslösemechanismus im Schaltbaustein 44 ist über eine dicht durch dessen Gehäuse 6 hindurchgeführte Welle 7 mit einem äußeren Rastarm 22, der aus Gründen eines reibungsarmen Aufbaues mit einer Rolle 22a ausgestattet ist, drehfest verbunden. Dieser äußere Rastarm 22 stützt im betriebsbereiten Zustand der Bindung den, um eine mit der Bindungsplatte 1 starr verbundene Drehachse 29 schwenkbaren, äußeren Stützhebel 21 ab, der als Widerlager für das eine Ende der Spannfeder 19 dient, die den die Rastbahn 31 tragenden Arm 18, wie bereits erläutert wurde, gegen die Rastrolle 16 des Sohlenniederhalters 17 des Fersenbackens 5 preßt.The trigger mechanism in the switching module 44 is connected in a rotationally fixed manner via a shaft 7 which is tightly passed through its housing 6 to an outer latch arm 22 which is equipped with a roller 22a for reasons of low friction. This outer latching arm 22 supports the outer support lever 21, which can be pivoted about an axis of rotation 29 rigidly connected to the binding plate 1, in the operational state of the binding, which acts as a Abutment for one end of the tension spring 19 is used, which, as already explained, presses the arm 18 carrying the latching track 31 against the latching roller 16 of the sole retainer 17 of the heel shoe 5.

Wie aus den Fig. 2a bis c ersichtlich ist, erfolgt die Abstützung des äußeren Stützhebels 21 an dem äußeren Rastarm 22 derart, daß der äußere Stützhebel 21 mit dem äußeren Rastarm 22 einen 90° geringfügig übersteigenden Winkel einschließt, um ein Drehmoment auf den äußeren Rastarm 22 auszuüben, das diesen gegen dessen Entriegelungsstellung vorspannt. Abgefangen wird dieses Drehmoment vom Auslösemechanismus, der dadurch gegen seine entriegelte Stellung vorgespannt wird. Dabei unterstützt das auf den Rastarm 22 einwirkende Moment eine allfällige Auslösung, so daß eine solche auch durch einen Eisansatz kaum nennenswert behindert wird und mit geringen, durch den Auslösemechanismus aufgebrachten Kräften eine Auslösung möglich ist.As can be seen from FIGS. 2a to c, the outer support lever 21 is supported on the outer locking arm 22 in such a way that the outer support lever 21 encloses a slightly larger angle with the outer locking arm 22 in order to apply a torque to the outer locking arm 22 exercise that biases this against its unlocked position. This torque is intercepted by the release mechanism, which is thereby biased against its unlocked position. The moment acting on the locking arm 22 supports a possible triggering, so that such an impact is hardly noticeably hampered even by ice build-up and a triggering is possible with low forces applied by the triggering mechanism.

Beim Hochschwenken des Sohlenniederhalters 17 nach einer erfolgten willkürlichen oder unwillkürlichen Auslösung kommt ein Ansatz 27 desselben an einem Fortsatz 27' des Rastarmes 22 zur Anlage und dreht diesen in seine Arbeitsstellung zurück. Dieses Rückdrehen des äußeren Rastarmes 22 bewirkt über die Welle 7 auch ein Rückstellen des Auslösemechanismus.When the sole hold-down device 17 is pivoted up after an arbitrary or involuntary triggering, an attachment 27 of the same comes to rest on an extension 27 'of the latching arm 22 and rotates it back into its working position. This turning back of the outer latch arm 22 also causes the trigger mechanism to be reset via the shaft 7.

Dieses Zurückdrehen erfordert nur wenig Kraft, da dabei die Spannfeder 19 nur auf die mittels der Koppelstange 20 verbundenen Teile, nämlich auf den Arm 18, und den Stützhebel 21 einwirkt und mit diesen ein in sich geschlossenes System bildet. Beim nachfolgenden Niederdrücken des Sohlenniederhalters 17 überdrückt dessen Rastrolle 16 den die Rastbahn 31 aufweisenden Arm 18, wobei die Spannfeder 19 zusammengedrückt wird. Der Sohlenniederhalter 17 ist damit wieder verriegelt.This turning back requires little force, since the tension spring 19 only acts on the parts connected by means of the coupling rod 20, namely on the arm 18, and the support lever 21 and forms a self-contained system with them. When the sole hold-down device 17 is subsequently pressed down, its locking roller 16 presses over the arm 18 having the locking track 31, the tension spring 19 being compressed. The sole hold-down device 17 is locked again.

Wie aus den Fig. 2 bis 5 zu ersehen ist, erfolgt die Anlenkung des Sohlenniederhalters 17 an der im wesentlichen skifest gehaltenen Bindungsplatte 1 über eine, z.B. durch ein Paar von Laschen 11 gebildete Laschenanordnung, die an zwei in der Arbeitsstellung des Fersenbackens 5 quer zum Ski 10 und parallel zu dessen Oberfläche 10a verlaufenden Achsen, u.zw. die bereits erwähnte Achse 9, an der der haubenförmige Sohlenniederhalter 17 angelenkt ist, und die Achse 12, die in der Bindungsplatte 1 bzw. einer von dieser aufragenden Rippe gehalten ist, gelagert sind. Damit ist der Sohlenniederhalter 17 mit der im wesentlichen skifesten Bindungsplatte 1 lediglich über die Laschen 11 verbunden, wobei die Verrastung des Sohlenniederhalters 17 mit der skifesten Bindungsplatte 1 über den die Rastbahn 31 tragenden Arm 18, der schwenkbar an der Bindungsplatte 1 gehalten ist, und die an dem Sohlenniederhalter 17 drehbar gehaltenen Rastrolle 16 erfolgt, die in der Arbeitsstellung des Sohlenniederhalters 17 von der Rastbahn 31 übergriffen ist.As can be seen from FIGS. 2 to 5, the articulation of the sole hold-down device 17 takes place on the binding plate 1, which is held essentially in the form of a ski, via a bracket arrangement formed, for example, by a pair of straps 11, which is attached to two in the working position of the heel jaw 5 transverse to the ski 10 and axes running parallel to its surface 10a, etc. the already mentioned axis 9, on which the hood-shaped sole hold-down device 17 is articulated, and the axis 12, which is held in the binding plate 1 or a rib projecting from it, are mounted. Thus, the sole hold-down device 17 is connected to the essentially ski-fixed binding plate 1 only via the tabs 11, the latching of the sole hold-down device 17 to the ski-fixed binding plate 1 via the arm 18 carrying the latching track 31, which is pivotably held on the binding plate 1, and the on the sole retainer 17 rotatably held locking roller 16 which is overlapped in the working position of the sole retainer 17 by the locking track 31.

Wie aus der Fig. 2a, in der die Verhältnisse dargestellt sind, wie sie sich bei einer optimalen Einstellung der Bindung ergeben, ersichtlich ist, drückt die Spannfeder 19 den Arm 18 in Richtung zu einem nur angedeuteten Schuh 50 hin, wobei der Arm 18 an der mit der Bindungsplatte 1 bzw. deren Rippe verbundenen Achse 28 angelenkt ist und gegen die Rastrolle 16 drückt, wobei sich auch eine in Skilängsrichtung wirkende Kraftkomponente ergibt. Diese Kraftkomponente bewirkt ein Vorschieben des Sohlenniederhalters 17 in Richtung zum Schuh 50 hin, wodurch es aufgrund der Anlenkung des Sohlenniederhalters 17 an der tieferliegenden Achse 9 zu einer gegenüber einer vertikalen Stellung der Laschen 11 geneigten Lage derselben kommt.As can be seen from FIG. 2 a, in which the relationships are shown as they result from an optimal setting of the binding, the tension spring 19 presses the arm 18 in the direction of an only indicated shoe 50, the arm 18 being on the axis 28 connected to the binding plate 1 or its rib is articulated and presses against the locking roller 16, which also results in a force component acting in the longitudinal direction of the ski. This force component causes the sole hold-down device 17 to be advanced in the direction of the shoe 50, which, due to the articulation of the sole hold-down device 17 on the lower axis 9, leads to an inclined position thereof relative to a vertical position of the tabs 11.

Ist nun eine geringfügige Abweichung von der idealen Einstellung des Fersenbackens 5 gegeben, was z.B. bei Schuhsohlen aus einem etwas hygroskopischen Material oder durch eine Schneeauflage nicht zu vermeiden ist, so kann diese Abweichung durch die Anlenkung des Sohlenniederhalters 17 über die Laschen 11 durch die letzteren aufgenommen werden, wie dies aus der Fig.2b zu ersehen ist. Dabei kommt es zu einer vertikalen bzw. zu einer leicht nach hinten geneigten Stellung der Lasche 11. Die Spannfeder 19 wird dadurch zwar etwas stärker komprimiert, doch ändert sich dadurch auch der Angriffspunkt der Spannfeder 19 an dem Arm 18, da dieser vertikaler steht und daher der Angriffspunkt der Spannfeder 19 nach unten wandert, aber deren Abstützpunkt gleich bleibt. Bei entsprechender Dimensionierung des Armes 18, des Stützhebels 21 und des äußeren Rastarmes 22 sowie deren Anlenkpunkte ist es möglich, eine von solchen Längenänderungen weitgehend unbeeinflußte Auslösecharakteristik zu erhalten.If there is now a slight deviation from the ideal setting of the heel cheek 5, which cannot be avoided, for example in the case of shoe soles made of a somewhat hygroscopic material or due to a snow covering, this deviation can be absorbed by the latter through the articulation of the sole hold-down device 17 via the tabs 11 be, as can be seen from Fig.2b. This results in a vertical or a slightly backward inclined position of the tab 11. The tension spring 19 is compressed somewhat more by this, but this also changes the point of application of the tension spring 19 on the arm 18, since it is more vertical and therefore the point of application of the tension spring 19 moves downward, but its support point stays the same. With appropriate dimensioning of the arm 18, the support lever 21 and the outer locking arm 22 and their articulation points, it is possible to obtain a release characteristic largely unaffected by such changes in length.

Ähnliches gilt auch in Bezug auf eine Schneeauflage unterhalb der Schuhsohle, wie dies in der Fig. 2c dargestellt ist. Dabei kommt es aufgrund der erhöhten Lage des Fersenbereiches der Sohle des Schuhs 50 zu einem Komprimieren der Spannfeder 19, und - aufgrund der Neigung der Rastbahn 31 - zu einer Veränderung der Hebelverhältnisse, wobei der an der Rastrolle 16 abgestützte Hebelarm des Armes 18 verkürzt wird. Die ein Auslösen bewirkenden Drehmomente werden somit auch bei unterschiedlichen Höhenlagen des Sohlenniederhalters 17 innerhalb enger und völlig unkritischer, im voraus bestimmbarer Grenzen gehalten. Durch entsprechende Dimensionierung kann daher erreicht werden, daß die Auslösebedingungen nicht oder nur unwesentlich verändert werden.The same applies in relation to a snow covering below the sole of the shoe, as shown in FIG. 2c. This results in a compression of the tension spring 19 due to the elevated position of the heel region of the sole of the shoe 50, and - due to the inclination of the latching track 31 - a change in the lever ratios, the lever arm of the arm 18 supported on the latching roller 16 being shortened. The torques causing tripping are thus kept within narrow and completely uncritical, predeterminable limits even at different heights of the sole hold-down device 17. Appropriate dimensioning can therefore ensure that the triggering conditions are not changed or are changed only insignificantly.

Fig. 3 zeigt den erfindungsgemäßen Fersenbacken 5 nach dem Auslösen des Schaltbausteines 44. Dabei hat der Rastarm 22 seine den Stützhebel 21 abstützende Stellung bereits verlassen und seine Freigabestellung erreicht. Dies ist durch die Entriegelung der den Rastarm 22 tragenden Welle 7 im Inneren des Schaltbausteines 44 und durch das vom Stützhebel 21 auf den Rastarm 22 in Richtung auf dessen Freigabestellung zu wirkende Moment bedingt. Dadurch hat aber auch die Spannfeder 19 ihr durch den Stützhebel 21 und den Rastarm 22 gebildetes Widerlager verloren, wodurch die Spannfeder 19 mit dem Arm 18 und dem Stützhebel 22 nur mehr ein geschlossenes System bildet, das keine Kräfte mehr nach außen ausübt. Dadurch kann, auch bei kleinen, vom Schuh 50 auf den Sohlenniederhalter 17 ausgeübten Kräften der Sohlenniederhalter 17 nach hinten verschoben werden, wie dies aus Fig. 4a und 4b zu ersehen ist, wobei es zu einer Auslenkung der Laschen 11 kommt. Weiters kann aber der Sohlenniederhalter 17 auch ohne nennenswerten Kraftaufwand nach oben verschwenkt werden, wobei letzteres noch durch die Öffnungsfeder 23 unterstützt wird.3 shows the heel jaw 5 according to the invention after the switching module 44 has been triggered. The latch arm 22 has already left its position supporting the support lever 21 and has reached its release position. This is due to the unlocking of the shaft 7 carrying the locking arm 22 in the interior of the switching module 44 and by the moment to be exerted by the support lever 21 on the locking arm 22 in the direction of its release position. As a result, the tension spring 19 has also lost its abutment formed by the support lever 21 and the locking arm 22, as a result of which the tension spring 19 with the arm 18 and the support lever 22 only forms a closed system which no longer exerts any forces on the outside. As a result, even with small forces exerted by the shoe 50 on the sole hold-down device 17, the sole hold-down device 17 can be displaced to the rear, as can be seen from FIGS. 4a and 4b, with the tabs 11 being deflected. Furthermore, the sole hold-down device 17 can also be pivoted upwards without any appreciable expenditure of force, the latter still using the opening spring 23 is supported.

Fig. 5 zeigt den erfindungsgemäßen Fersenbacken mit nach einer Auslösung hochgeschwenktem Sohlenniederhalter 17, wobei, wie bereits erwähnt, durch das Hochschwenken des Sohlenniederhalters 17 der Rastarm 22 und damit der Auslösemechanismus im Schaltbaustein 44 zurückgestellt wurden. Letzteres erfolgt mit Hilfe des an dem Sohlenniederhalter 17 angeordneten Ansatzes 27, der an dem Fortsatz 27' des Rastarmes 22 zur Anlage kommt und diesen mitnimmt.5 shows the heel jaw according to the invention with the sole hold-down device 17 pivoted up after a release, wherein, as already mentioned, the latching arm 22 and thus the release mechanism in the switching module 44 have been reset by pivoting the sole hold-down device 17 up. The latter takes place with the aid of the attachment 27 arranged on the sole hold-down device 17, which comes to rest on the extension 27 'of the latching arm 22 and takes it along.
