Abstract

PCT No. PCT/EP87/00443 Sec. 371 Date May 2, 1988 Sec. 102(e) Date May 2, 1988 PCT Filed Aug. 12, 1987 PCT Pub. No. WO88/01191 PCT Pub. Date Feb. 25, 1988.The present invention concerns a ski safety binding including an electronic analyzer connected to force pickups that emit electrical signals. An electric power supply such as a battery is provided. An electromechanical release element controls a locking mechanism for acting on a heel holder or piece. The electromechanical release element has at least one stop member. To assure high reliability even in the severe weather conditions, the present invention mounts the electromechanical release member inside a well sealed housing. A drive control member is positioned in sealed manner through the wall of the housing. The drive control member includes a shaft and controls the locking mechanism that acts on the heel piece.

Description

Die Erfindung bezieht sich auf eine Sicherheitsschibindung mit einer elektronischen Auswerteschaltung, die mit elektrische Signale abgebenden Kraftaufnehmern, einer elektrischen Stromversorgung, z.B. einer Batterie und einem elektromechanischen Auslöseglied verbunden ist, wobei das mindestens eine Rastenanordnung aufweisende Auslöseglied ein Steuerglied antreibt, das einen an einem Fersenbacken angreifenden Verriegelungsmechanismus steuert.The invention relates to a safety ski binding with an electronic evaluation circuit, the force transducers emitting electrical signals, an electrical power supply, e.g. is connected to a battery and an electromechanical trigger member, the trigger member having at least one catch arrangement driving a control member which controls a locking mechanism acting on a heel shoe.

Es sind eine Reihe von Vorschlägen für solche Schibindungen bekannt. Allen diesen Vorschlägen gemeinsam ist eine offene Anordnung des elektromechanischen Auslösegliedes in einem Backen, das heißt, daß das Auslöseglied den Witterungseinflüssen nur wenig geschützt ausgesetzt ist. Dabei kann es leicht zu Vereisungen oder Verschmutzungen kommen, wodurch die Funktion einer solchen Bindung nicht mehr einwandfrei sichergestellt werden kann, da im Hinblick auf einen geringen Leistungsverbrauch nur mit relativ kleinen Auslösekräften gearbeitet werden kann. Mit diesen ist es aber z.B. nicht möglich, einen, wenn auch geringen Eisansatz abzusprengen, oder eine durch Verschmutzung erhöhte Haftreibung des Verriegelungsmechanismus zu überwinden.A number of proposals for such ski bindings are known. Common to all of these proposals is an open arrangement of the electromechanical trigger element in a jaw, that is to say that the trigger element is exposed to the weather influences with little protection. This can easily lead to icing or soiling, which means that the function of such a binding can no longer be properly ensured, since in view of a low power consumption, only relatively small triggering forces can be used. With these it is e.g. not possible to blow off a small amount of ice, or to overcome an increased static friction of the locking mechanism due to dirt.

So wurde z.B. durch die FR-PS 2 375 880 eine Sicherheitsschibindung bekannt, bei der die Rastenanordnung durch eine Klinke gebildet ist, die mittels einer von einem Elektromagneten antreibbaren, axial verschiebbaren Stange gesteuert ist. Bei dieser Schibindung ist der Elektromagnet in einem an seiner Unterseite eine öffnung aufweisenden Backen angeordnet und daher dem allenfalls eindringenden Schnee praktisoh schutzlos ausgesetzt. Damit besteht aber bei dieser Lösung eine sehr große Gefahr des Vereisens der Rastenanordnung und des Elektromagneten, sodaß die bekannte Schibindung kaum den Sicherheitsanfordenungen unter den Bedingungen eines normalen Einsatzes genügen kann.For example, through FR-PS 2 375 880 a safety ski binding is known in which the catch arrangement is formed by a pawl which is controlled by means of an axially displaceable rod which can be driven by an electromagnet. In this ski binding, the electromagnet is arranged in a jaw having an opening on its underside and is therefore practically exposed to the snow that may penetrate. With this solution, however, there is a very great risk of the latch arrangement and the electromagnet icing up, so that the known ski binding can hardly meet the safety requirements under the conditions of normal use.

Weiters wurde durch die AT-PS 307 943 eine Schibindung vorgeschlagen, bei der die Rastenanordnung ebenfalls von einem Elektromagneten gesteuert ist. Bei dieser Lösung ist zwar ein geschlossener Backen vorgesehen, in dem der Elektromagnet angeordnet ist, doch ist dieser Backen von einer Reihe von Betätigungsorganen mit erheblichem Spiel durchsetzt, wodurch Wasser eindringen kann, was letztlich zur Vereisung und damit Blockierung der Auslöseeinrichtung führen kann.Furthermore, AT-PS 307 943 proposed a ski binding in which the catch arrangement is also controlled by an electromagnet. In this solution, a closed jaw is provided, in which the electromagnet is arranged, but this jaw is penetrated by a series of actuators with considerable play, whereby water can penetrate, which can ultimately lead to icing and thus blocking of the triggering device.

Im bekannten Falle wird der Schischuh mittels einer Drehraste gehalten, wobei die Welle für den Antrieb dieser Raste in Kugellager gelagert ist, die jedoch keineswegs abgedichtet sind. Dabei ist auch noch zu berücksichtigen, daß es in weitgehend geschlossenen Räumen durch Temperatur-und Luftdruckschwankungen zu einer Ansammlung von Wasser kommen kann, da die Luftfeuchtigkeit, die durch Temperaturschwankungen, die entsprechende Druckschwankungen im Inneren des Backens bedingen, in das Innere über kleinste Spalte eindringt, kondensiert und dieses Kondensat nur sehr schwer wieder abläuft, wodurch ebenfalls die Gefahr der Vereisung steigt.In the known case, the ski boot is held by means of a rotary catch, the shaft for driving this catch being mounted in ball bearings, which, however, are in no way sealed. It must also be taken into account that water can accumulate in largely closed rooms due to fluctuations in temperature and air pressure, since the air humidity, which is caused by temperature fluctuations and the corresponding pressure fluctuations inside the jaw, penetrates into the interior through the smallest gaps , condenses and this condensate is very difficult to drain again, which also increases the risk of icing.

Ziel der Erfindung ist es, diese Nachteile zu vermeiden, und eine Schibindung der eingangs erwähnten Art vorzuschlagen, die auch unter den, beim Wintersport herrschenden, schwierigen Bedingungen zuverlässig arbeitet.The aim of the invention is to avoid these disadvantages and to propose a ski binding of the type mentioned at the outset which operates reliably even under the difficult conditions prevailing in winter sports.

Erfindungsgemäß wird dies dadurch erreicht, daß das elektromechanische Auslöseglied in einem rundum dicht geschlossenen Gehäuse angeordnet ist und das Steuerglied als eine durch die Wand des Gehäuses dicht hindurchgeführte Welle ausgeführt ist. Dadurch ist der empfindlichste Teil der Bindung gegen Witterungseinflüsse, insbesondere gegen einen Eisansatz und Verschmutzung voll geschützt, wobei, falls die Welle eine Drehraste steuert, oder selbst als eine solche ausgebildet ist, nur geringe Steuerkräfte zur Bewegung der Welle von der Verriegelungsstellung in die Entriegelungsstellung notwendig sind.According to the invention, this is achieved in that the electromechanical triggering member is arranged in an all-round sealed housing and the control member is designed as a shaft which is tightly guided through the wall of the housing. As a result, the most sensitive part of the binding is fully protected against the effects of the weather, in particular against ice build-up and contamination, and if the shaft controls a rotary catch, or is itself designed as such, only slight control forces are required to move the shaft from the locked position to the unlocked position are.

Nach einem weiteren Merkmal der Erfindung kann vorgesehen sein, daß das Gehäuss mit einem trockenen Schutzgas oder einer bis zumindest -30°C flüssig bleibenden, vorzugsweise elektrisch isolierenden Flüssigkeit, wie z.B. synthetisches öl, gefüllt ist, wodurch ein besonderes hohes Maß an Schutz erreicht wird. Außerdem lassen sich bei einer Füllung mit einem öl oder dergleichen allfällig auftretend Leckagen, die zu einer Beeinträchtigung der Funktionssicherheit führen könnten, sicher erkennen.According to a further feature of the invention it can be provided that the housing with a dry protective gas or a preferably electrically insulating liquid, such as e.g. synthetic oil, filled, which provides a particularly high level of protection. In addition, any leaks that could lead to an impairment of the functional reliability can be reliably identified when filled with an oil or the like.

Bei einer erfindungsgemäßen Sicherheitsschibindung bei der das elektromechanische Auslöseglied durch einen Elektromagneten gebildet ist, kann nach einem weiteren Merkmal der Erfindung vorgesehen sein, daß der Elektromagnet einen Klappanker mit einer Rastfläche aufweist, an der in der Arbeitslage des Fersenbackens ein gegen seine entriegelte Stellung vorgespannter, im Inneren des Gehäuses angeordneter innerer Hebel gegen eine Bewegung in Richtung seiner entriegelter Stellung abgestutzt ist. Dadurch kann die Bindung mit sehr kleinen Kräften, die von dem Elektromagneten ohne weiters aufgebracht werden können, ausgelöst werden. Dies ist dadurch bedingt, daß der Elektromagnet lediglich die, durch die auf diese innere Raste einwirkenden Kräfte bedingte, Reibungskraft überwinden muß. Auf diese Weise gelingt es, die für die Auslösung der Bindung notwendige Kraft besonders klein zu halten, wobei aber gleichzeitig hohe Haltekräfte auf den Fersenbacken ausgeübt werden können.In a safety ski binding according to the invention, in which the electromechanical release member is formed by an electromagnet, it can be provided according to a further feature of the invention that the electromagnet has a hinged armature with a latching surface, on which, in the working position of the heel shoe, a biased against its unlocked position, in Inside the housing arranged inner lever is supported against movement in the direction of its unlocked position. As a result, the binding can be triggered with very small forces that can be easily applied by the electromagnet. This is due to the fact that the electromagnet only has to overcome the frictional force caused by the forces acting on this inner detent. In this way it is possible to keep the force required to release the binding particularly small, but at the same time high holding forces can be exerted on the heel cheeks.

Dabei kann weiters vorgesehen sein, daß der an der Rastfläche des Klappankers zur Anlage kommende innere Hebel drehfest mit der als Steuerglied dienenden und das Gehäuse durchsetzenden Welle verbunden ist, die außerhalb des Gehauses eine Raste steuert oder selbst, z.B. durch eine Abflachung, als Raste ausgebildet ist, wobei der innere Hebel mit einer Feder gegen seine Entriegelungsstellung vorgespannt ist, deren Kraft ein Drehmoment auf die Welle ausübt, das das durch die Belastung der außerhalb des Gehäuses befindlichen äußeren Raste auf die Welle einwirkenden Kräfte bedingten Reibungskräfte verursachte Moment übersteigt. Praktisch ergibt sich dabei ein aktiver Schaltbaustein, der bei einer Auslösung durch den Elektromagneten durch die in seiner Feder gespeicherte Energie eine Drehung der Welle auch bei Fehlen von außeren, auf die Welle einwirkenden Kräften erzwingt.It can further be provided that the inner lever coming to rest on the locking surface of the hinged anchor is connected in a rotationally fixed manner to the shaft which serves as a control member and penetrates the housing and which controls a detent outside the housing or is designed as a detent itself, for example by flattening is, the inner lever is biased by a spring against its unlocked position, the force of which exerts a torque on the shaft practices that the frictional forces caused by the load of the external detent located outside the housing acting on the shaft forces exceeds. In practice, this results in an active switching module which, when triggered by the electromagnet, forces the shaft to rotate due to the energy stored in its spring, even in the absence of external forces acting on the shaft.

Um bei einer solchen Bindung mit sehr kleinen Steuerkräften das Auslangen zu finden, kann weiters vorgesehen sein, daß an der von der das Gehäuse durchsetzenden Welle gesteuerten, oder durch diese gebildeten Raste, außerhalb des Gehäuses ein gegen seine Entriegelungsstellung vorgespannter äußerer Kurvenhebel zur Anlage bringbar ist, an dem sich ein als Widerlager für eine Spannfeder dienender äußerer Rastarm abstützt, und die Spannfeder einen eine Nase des Fersenbackens in dessen Arbeitslage übergreifenden äußeren Rasthebel gegen dessen Verriegelungsstellung vorspannt.In order to find sufficiency in such a bond with very small control forces, it can further be provided that an external cam lever biased against its unlocked position can be brought into contact with the catch controlled by the shaft passing through the housing, or formed by it, outside the housing , on which an outer latch arm serving as an abutment for a tension spring is supported, and the tension spring prestresses an outer latch lever overlapping a nose of the heel shoe in its working position against its locking position.

Dabei kann es zwar bei der außerhalb des Gehäuses liegenden Raste zu einem Eisansatz oder einer Verschmutzung kommen, doch stört dies nicht besonders, da bei dieser entsprechend hohe Kräfte auftreten, so daß eine Vergrößerung der Haltekräfte aufgrund einer Verschmutzung keine wesentliche Verminderung der Auslösesicherheit mit sich bringt, da die erforderliche Auslösekraft durch eine entsprechende Dimensionierung der an dem mit der Raste zusammenwirkenden Kurvenhebel angreifenden Feder sichergestellt werden kann.This can lead to ice build-up or contamination in the catch located outside the housing, but this is not particularly disturbing, since correspondingly high forces occur in this case, so that an increase in the holding forces due to contamination does not result in a significant reduction in the triggering safety , since the required release force can be ensured by appropriate dimensioning of the spring acting on the cam lever interacting with the detent.

Eine weitere sehr vorteilhafte Ausführungsform einer erfindungsgemäßen Schibindung zeichnet sich dadurch aus, daß der an der Rastfläche des Klappankers zur Anlage kommende innere Hebel eine Ausnehmung aufweist, in die ein, vorzugsweise an seinem freien Ende abgewinkelter, oder bügelformig ausgebildeter, mit der das Gehäuse durchsetzenden Welle drehfest verbundener, im Inneren des Gehäuses angeordneter innerer Rastarm eingreift, wobei außerhalb des Gehauses ein äußerer Rastarm mit der Welle drehfest verbunden ist, an dem sich im verriegelten Zustand ein außerhalb des Gehäuses angeordneter äußerer Stützhebel abstützt, der als Widerlagerfur eine Spannfeder dient, die einen den Fersenbacken in seiner verriegelten Arbeitslage haltenden äußeren Rasthebel gegen dessen Verriegelungsstellung vorspannt, wobei dieser äußere Rastarm in der betriebsbereiten Stellung der Bindung einen geringfügig größeren Winkel als 90° mit dem äußeren Stützhebel einschließt, um ein geringes, gegen die Entriegelungsstellung des äußeren Rastarmes gerichtetes Drehmoment auf diesen und damit auf die Welle auszuüben. Damit wird die Auslösung durch den Schaltbaustein aktiv durch die von außen auf diesen einwirkenden Kräfte unterstutzt.Another very advantageous embodiment of a ski binding according to the invention is characterized in that the inner lever which comes into contact with the latching surface of the hinged anchor has a recess into which a shaft, preferably angled at its free end, or formed in a bow shape, with the shaft penetrating the housing rotatably connected, arranged inside the housing locking arm engages, outside of the housing an outer locking arm is rotatably connected to the shaft, on which, in the locked state, an outer support lever arranged outside the housing is supported, which serves as an abutment for a tension spring that one the heel jaw in its locked working position holding the outer locking lever against its locking position, this outer locking arm in the ready position of the binding includes a slightly larger angle than 90 ° with the outer support lever to a geri Nges, against the unlocking position of the outer locking arm torque on this and thus to exert on the shaft. Thus the triggering by the switching module is actively supported by the forces acting on it from the outside.

Bei dieser Lösung ergibt sich der Vorteil, daß die Federkräfte im Inneren des Gehäuses des Schaltbausteines sehr klein gehalten werden können, wobei Federn verwendet werden können, die praktisch nur eine Festlegung einer bestimmten Lage der einzelnen Teile und zwar des Klappankers und des die Ausnehmung aufweisenden inneren Hebels ermöglichen. Dadurch sind nach einer Auslösung der Bindung nur sehr geringe Kräfte zur Rückstellung der einzelnen Teile in eine die Verriegelung der Bindung ermöglichende, betriebsbereite Lage notwendig. Dabei genügt es den außerhalb des Gehäuses des Schaltbausteines mit der Welle verbundenen äußeren Rastarm zu verdrehen, da dieser die Welle und damit, den in die Ausnehmung des inneren Hebels eingreifenden inneren Rastarm mitdreht, wodurch auch der innere Hebel in seine Arbeitslage zurückgedreht wird. Ist dies geschehen, so kann der Klappanker aufgrund der auf diesen einwirkenden schwachen Feder den inneren Hebel wieder an seiner Rastfläche abstützen. Die Rückstellung des äußeren Rastarmes kann dabei bei einem im ausgelösten Zustand der Bindung mittels einer Feder, hochschwenkbaren Fersenbacken mittels eines an diesem angebrachten Vorsprunges erfolgen, der den äußeren Rastarm beim Hochschwenken mitnimmt und diesen in dessen Arbeitsstellung bringt.This solution has the advantage that the spring forces inside the housing of the switching module can be kept very small, whereby springs can be used which practically only define a certain position of the individual parts, namely the hinged armature and the interior having the recess Allow lever. As a result, only very small forces are required to reset the individual parts into a ready-to-operate position which enables the locking of the binding after the binding has been released. It is sufficient to twist the outer locking arm connected to the shaft outside the housing of the switching module, since this rotates the shaft and thus the inner locking arm engaging in the recess of the inner lever, as a result of which the inner lever is also turned back into its working position. Once this has been done, the hinged anchor can support the inner lever on its locking surface again due to the weak spring acting on it. The resetting of the outer locking arm can take place in a released state of the binding by means of a spring, heel jaws which can be swiveled up by means of a projection which is attached to it and which takes the outer locking arm with it when swiveled up and brings it into its working position.

Um die erfindungsgemäße Bindung willkürlich auslösen zu können, kann vorgesehen sein, daß in dem Gehäuse ein federbelasteter Auslösestift gehalten ist, der von der Außenseite des Gehäuses her, vorzugsweise über eine Membrane betätigbar ist und auf das Auslöseglied einwirkt. Auf diese Weise wird ein unnötiger Verbrauch der Batterie beim Normalausstieg aus der Bindung vermieden.In order to be able to trigger the binding according to the invention at will, it can be provided that a spring-loaded trigger pin is held in the housing, which can be actuated from the outside of the housing, preferably via a membrane, and acts on the trigger member. In this way, unnecessary consumption of the battery when the binding is normally released is avoided.

Zur Erzielung eines kompakten Aufbaues und zur Vermeidung längerer und nur schwer schützbarer elektrischer Leitungen, kann nach einem weiteren Merkmal der Erfindung vorgesehen sein, daß an das Gehäuse eine Kammer angebaut ist, in der die Auswerteschaltung und gegebenenfalls auch die Batterie untergebracht sind. Dadurch können die elektrischen Leitungen gegen Umwelteinflüsse, insbesondere Verschmutzung vollkommen geschützt, geführt werden, da praktisch nur Durchführungen für diese Leitungen erforderlich sind.To achieve a compact structure and to avoid longer and difficult to protect electrical lines, it can be provided according to a further feature of the invention that a chamber is attached to the housing, in which the evaluation circuit and possibly also the battery are housed. As a result, the electrical lines can be completely protected against environmental influences, in particular contamination, since practically only bushings for these lines are required.

In diesem Zusammenhang ist es besonders vorteilhaf wenn das Gehäuse mit Kraftaufnehmern und der Bindungsplatte verbunden und über ein Meßelement mit kugelförmigem Ende an einem schifesten Widerlager abgestützt ist. Dies ermöglicht es auch die zu den Kraftaufnehmern führenden Leitungen durch das Gehäuse zu führen, so daß diese gegen eine mechanische Beschädigung geschützt geführt sind, wodurch sie bei Betätigung des Fersenbackens nicht bewegt werden und daher nicht brechen können.In this context, it is particularly advantageous if the housing is connected to force transducers and the binding plate and is supported on a thrust abutment by a measuring element with a spherical end. This also makes it possible to lead the lines leading to the force transducers through the housing, so that they are guided so as to be protected against mechanical damage, as a result of which they cannot be moved when the heel jaw is actuated and therefore cannot break.

Die Erfindung wird nun an Hand der Zeichnung näher erläutert. Dabei zeigt Fig. 1 schematisch den Aufbau einer Bindung; Fig. 2 schematisch eine erste Ausführungsform eines auslösbaren Backens nach der Erfindung im verriegelten Zustand; Fig. 3 den Backen gemäß Fig. 2 im ausgelösten Zustand; Fig. 4 den Backen gemäß Fig. 2 und 3 im entriegelten, einstiegsbereiten Zustand; Fig. 5 schematisch eine weitere Ausführungsform eines auslösbaren Backens nach der Erfindung im verriegelten Zustand; Fig. 6 den Backen gemäß Fig. 5 im ausgelösten Zustand und Fig. 72 den Backen gemäß Fig. 5 und 6 im entriegelten, einstiegsbereiten Zustand. Fig. 2a und 5a sind Teildraufsichten zu Fig. 2 bzw. 5 und Fig. 2b ein Detail hiezu.The invention will now be explained in more detail with reference to the drawing. 1 schematically shows the structure of a binding; Fig. 2 shows schematically a first embodiment of a releasable jaw according to the invention in the locked state; 3 shows the jaws according to FIG. 2 in the triggered state; Fig. 4 the jaws of FIG. 2 and 3 in the unlocked, ready-to-go state; 5 schematically shows a further embodiment of a releasable jaw according to the invention in the locked state; 6 shows the jaws according to FIG. 5 in the released state and FIG. 72 shows the jaws according to FIGS. 5 and 6 in the unlocked, ready-for-use state. 2a and 5a are partial top views of Fig. 2 and 5 and Fig. 2b a detail of this.

Die in Fig. 1 dargestellte Bindung ist als Plattenbindung ausgebildet, wobei die Bindungsplatte 1 um einen ballig ausgeführten Zapfen 40 drehbar ist, der im Bereich des Durchstoßpunktes der Achse der Tibia des Schiläufers mit der Schiebene angeordnet ist und eine Drehung der Bindungsplatte in der Ebene des Schis ermöglicht. Im vorderen Bereich der Bindungsplatte 1 weist diese eine Achse 41 auf, die einen in Schilängsrichtung verlaufenden Schlitz 42 einer schifest angeordneten Halterung 45 durchsetzt, die in eine, an der Unterseite der Bindungsplatte 1 angeordnets Ausnehmung mit allseitig großem Spiel hineinragt, wodurch eine beschränkte Verdrehung der Bindungsplatte um den Zapfen 40 und ein Hochschwenken der Bindungsplatte 1 um die Achse 41 möglich ist.The binding shown in Fig. 1 is designed as a plate binding, the binding plate 1 is rotatable about a spherical pin 40, which is arranged in the region of the point of intersection of the axis of the tibia of the skier with the sliding plane and a rotation of the binding plate in the plane of Ski enabled. In the front region of the binding plate 1, this has an axis 41 which passes through a slot 42 of a formally arranged holder 45 which extends in the longitudinal direction of the ski and which projects into a recess arranged on the underside of the binding plate 1 with great play on all sides, as a result of which a limited rotation of the Binding plate around the pin 40 and pivoting the binding plate 1 around 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 faststellbar gehalten.Furthermore, in the front area of the binding plate 1, a rigid, non-releasable toe cheek 43 is held in the longitudinal direction of the binding plate so that it can be adjusted and fastened.

Der im hinteren Bereich der Bindungsplatte angeordnete auslösbare Fersenbacken 17 ist mit der Bindungsplatte 1 verbunden und um die Achse 9 hochschwenkbar, die in einer aufragenden Rippe der Bindungsplatte 1 gehalten 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 schifesten Widerlager 2 abgestützt ist.The releasable heel shoe 17 arranged in the rear region of the binding plate is connected to the binding plate 1 and can be swiveled up about the axis 9, which is held in an upstanding rib of the binding plate 1. Furthermore, the binding plate 1 is firmly connected in its rear area to a switching module 44, which is supported in a shifter 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 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 fixed in its position, 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 around the pin 40 and the axis 41, the detection of the on the binding plate 1 allow acting moments ± Mz and ± My.

Es werden vorerst jene Merkmale beschrieben, die für beide Ausführungsformen der auslösbaren Fersenbacken 17 gemeinsam sind. Dabei werden die zum Verriegelungsmechanismus des Backens gehörenden, innerhalb des Gehäuses 6 des Schaltbausteines 44 angeordneten Teile stets als "innere" Teile und die außerhalb dieses Gehäuses 6 angeordneten Teile des Verriegelungsmechanismus als "äußere" Teile bezeichnet.For the time being, those features are described that are common to both embodiments of the releasable heel jaws 17. The parts belonging to the locking mechanism of the jaw and arranged inside the housing 6 of the switching component 44 are always referred to as "inner" parts and the parts of the locking mechanism arranged outside this housing 6 are referred to as "outer" parts.

In beiden Ausführungsformen der Erfindung ist das Gehäuse 6 des Schaltbausteines 44 rundum dicht geschlossen. Dabei sind in den einzelnen Fig. 2 bis 4 bzw. 5 bis 7 jeweils drei Schrauben 6c erkennbar, mittelsderen am Gehäuse 6 eine seitliche Abdeckwand 6b befestigt ist. Die Abdeckwand 6b sitzt dabei, unter Zwischenschaltung eines Dichtungsringes, in bekannter und näher weder beschriebener noch dargestellter Weise mit einer Nut an einer Dichtungsrippe des Gehäuses 6 an.In both embodiments of the invention, the housing 6 of the switching component 44 is tightly sealed all around. Three screws 6c can be seen in the individual FIGS. 2 to 4 and 5 to 7, by means of which screws a side cover wall 6b is fastened to the housing 6. The cover wall 6b sits, with the interposition of a sealing ring, with a groove on a sealing rib of the housing 6 in a known and not described or illustrated manner.

Zufolge der seitlichen Anordnung der Abdeckwand 6b am Gehäuse 6 wird dessen Inneres für Montagezwecke leicht zugänglich, wobei auch Lagerstellen ausgebildet werden können, ohne daß die Seitenwand 6a und/oder die Abdeckwand 6b des Gehäuses 6 durchgebohrt und zusätzlich abgedichtet werden müßte bzw. müßten. Auf Einzelheiten notwendiger Abdichtungen wird später noch eingegangen werden.As a result of the lateral arrangement of the cover wall 6b on the housing 6, the interior thereof is easily accessible for assembly purposes, bearing locations also being able to be formed without the side wall 6a and / or the cover wall 6b of the housing 6 having to be drilled through and additionally sealed. Details of the necessary seals will be discussed later.

Das Gehäuse 6 kann aus einem für Abdichtungen geeigneten Kunststoffmaterial, z.B. aus Polyamid oder Polyacetal, gefertigt werden. Es ist aber vorteilhaft, das Gehäuse 6 aus einem Leichtmetall-Material, z.B. aus einer Allminium- oder Magnesium-Legierung herzustellen, um auch die Bildung von Kondenswasser zu vermeiden. Allfällig entstehendes Kondenswasser könnte u.U. zu unerwünschten Eisbildungen im Inneren des Gehäuses 6 führen, wodurch eine einwandfreie Funktion des Verriegelungsmechanismus beeinträchtigt werden könnte.The housing 6 can be made of a plastic material suitable for seals, e.g. made of polyamide or polyacetal. However, it is advantageous to make the housing 6 from a light metal material, e.g. To be made from an Allminium or Magnesium alloy to avoid the formation of condensation. Any condensation water that forms could lead to undesirable ice formation inside the housing 6, which could impair the proper functioning of the locking mechanism.

Bei beiden Ausführungsformen ist beim Fersenbacken 17 eine übliche Aufschwenkfeder 23 vorgesehen, die an der Bindungsplatte 1 und dem Fersenbacken 17 abgestützt ist und diesen in Richtung seiner in den Fig. 3 und 6 strichliert angedeuteten und in den Fig. 4 und 7 dargestellten, hochgeschwenkten Endstellung vorspannt.In both embodiments, a conventional swing-open spring 23 is provided in the heel shoe 17, which is supported on the binding plate 1 and the heel shoe 17 and this in the direction of its upward pivoted end position indicated in dashed lines in FIGS. 3 and 6 and shown in FIGS. 4 and 7 preloaded.

Der Fersenbacken 17 weist eine gegen sein Inneres vorstehende Rastnase 16 auf, die in der verriegelten Stellung der Bindung von einer Rolle 18a eines äußeren Rasthebels 18 übergriffen ist. Dieser äußere Rasthebei 18 ist an einer Drehachse 28 schwenkbar gehalten, die ihrerseits am bindungsplattenfesten Teil des Fersenbackens 17 fixiert ist. Am äußeren Rasthebel 18 ist eine Koppelstange 20 angelenkt, die den äußeren Rasthebel 18 mit einem um eine mit der Bindungsplatte 1 starr verbundene weitere Drehachse 29 schwenkbaren, noch näher zu beschreibenden.The heel jaw 17 has a locking lug 16 projecting against its interior, which is overlapped by a roller 18a of an outer locking lever 18 in the locked position of the binding. This outer latch 18 is pivotally held on an axis of rotation 28, which in turn is fixed to the part of the heel shoe 17 fixed to the binding plate. A coupling rod 20 is articulated on the outer latching lever 18, which links the outer latching lever 18 with an axis of rotation 29, which is rigidly connected to the binding plate 1 and can be described in more detail.

Stützglied verbindet, wobei die Koppelstange 20 in an diesen beiden Teilen angelenktan Abstützungen 46 einer Spannfeder 19 mit einem größeren Spiel und in ihrer Längrichtung verschiebbar gehalten ist. Die Stützglieder 21 bzw. 22 sind bei den dargestellten Ausführungsbeispielen unterschiedlich ausgebildet, erfüllen aber in beiden Fällen die gleiche Funktion und werden bei der Beschreibung der einzelnen Ausführungsformen noch gesondert erläutert.Support member connects, wherein the coupling rod 20 is articulated to these two parts on supports 46 of a tension spring 19 with a larger game and slidably in its longitudinal direction. The support members 21 and 22 are designed differently in the illustrated embodiments, but perform the same function in both cases and are explained separately in the description of the individual embodiments.

Zwischen den über die Koppelstange 20 miteinander verbundenen Teilen wirkt die Spannfeder 19, die die beiden Teile auseinander drängt. Damit wird der äußere Rasthebel 18 bei abgestütztem Stützglied gegen die Rastnase 16 gepreßt, wodurch der Fersenbacken 17 an einem Hochschwenken gehindert ist.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 outer locking lever 18 is pressed against the locking lug 16 with the support member supported, as a result of which the heel shoe 17 is prevented from swinging up.

In dem Fersenbacken 17 ist ein Handauslöseknopf 15 über eine Achse 30 schwenkbar gelagert, wobei dieser Knopf 15 mittels einer Feder 31 gegen seine inaktive Lage vorgespannt ist. Beim Drücken des Auslöseknopfes 15 schwenkt dieser im Gegenuhrzeigersinn bzw. entgegen der Kraft der Feder 31 und drückt auf den Auslösestift 14, der in einer Durchführung des Gehäuses 6 gehalten und mittels einer Feder 14a gegen seine in den Figuren dargestellte inaktive Lage vorgespannt ist. Dieser Auslösestift 14 ist den dargestellten Ausführungsbeispielen mittels eines O-Ringes 14b 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 Auslöseknopf 15 zur Anlage bringbar ist.In the heel shoe 17, a hand release button 15 is pivotally mounted about an axis 30, this button 15 being biased against its inactive position by means of a spring 31. At the Pressing the release button 15 pivots it counterclockwise or against the force of the spring 31 and presses the release pin 14, which is held in a passage of the housing 6 and is biased by a spring 14a against its inactive position shown in the figures. This trigger pin 14 is sealed to the illustrated embodiments by means of an O-ring 14b 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 release button 15 can be brought into contact.

Auf dem schifesten Widerlager 2 ist das Meßelement 3 uber seine kugelgelenkformige Aufnahme abgestützt. Dieses Meßelement 3 weist Kraftaufnehmer 4 auf, die die auf die Bindungsplatte 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 Dehungsmeßstreifen ausgebildet sein können, sind mit dem Gehäuse 6 des Schaltbausteines 44 verbunden, in dem die Batterie, die Auswerteschaltung 5, sowie ein elektromechanisches Auslöseelement, z.B. wie bei den dargestellten Ausführungsbeispielen, ein Elektromagnet und Teile des mechanischen Verriegelungssystems der Bindung untergebracht sind. Bezüglich des Auslösaelementes ist zu bemerken, daß dieses auch durch andere Bauteile, wie z.B. einem piezoelektrischen Wandler gebildet sein kann.The measuring element 3 is supported on the shifter-like abutment 2 via its ball-joint-shaped receptacle. This measuring element 3 has force transducers 4, which detect the moments ± My and ± Mz occurring on the binding plate about their axes of rotation and convert them into electrical signals. These force transducers 4, which e.g. can be designed as a piezoelectric transducer or as a strain gauge are connected to the housing 6 of the switching module 44, in which the battery, the evaluation circuit 5, and an electromechanical trigger element, e.g. as in the illustrated embodiments, an electromagnet and parts of the 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, such as a piezoelectric transducer can be formed.

Die die Batterie aufnehmende nicht dargestellte Kammer, sowie die die elektronische Auswerteschaltung 5 aufnehmende Kammer 32, die vor der die Batterie aufnehmenden Kammer liegt, sind an das Gehäuse 6 des Schaltbausteines 44 angebaut bzw. sind durch Teile desselben gebildet. Bei beiden dargestellten Ausführungsformen einer erfindungsgemäßen Bindung sind die elektromechanischen Auslöseelemente durch einen, einen Klappanker 11 aufweisenden Elektromagneten 13 gebildet, der über nicht dargestellte Leitungen mit der Auswerteschaltung 5 bzw. der Batterie verbunden ist. Der Klappanker 11 ist bei beiden Rusführungsformen mittels einer schwachen Rückstellfeder 12 gegen seine vom Kern abgefallene Stellung vorgespannt und weist eine Rastfläche 33 auf, an der ein Teil des Verriegelungsmechanismus des Fersenbackens 17 zur Anlage bringbar ist.The chamber, not shown, which holds the battery, and the chamber 32, which houses the electronic evaluation circuit 5 and which lies in front of the chamber which houses the battery, are attached to the housing 6 of the switching component 44 or are formed by parts of the same. In both of the illustrated embodiments of a binding according to the invention, the electromechanical triggering elements are formed by an electromagnet 13 having a hinged armature 11, which is connected to the evaluation circuit 5 or the battery via lines (not shown). The hinged armature 11 is biased against its position dropped from the core by means of a weak return spring 12 and has a locking surface 33 against which part of the locking mechanism of the heel shoe 17 can be brought into contact.

Bei der Ausführungsform gemäß Fig. 2 bis 4 liegt im betriebsbereiten Zustand der Bindung ein klinkenartiger innerer Hebel 10 an dem abgefallenen Klappanker 11 an. Dieser innere Hebel 10 ist um eine im Gehäuse 6 gehaltene Achse 34 schwenkbar gehalten und mittels einer schwachen Feder 35 gegen seine Entriegelungsstellung vorgespannt. Dieser innere Hebel 10 weist eine randoffene Ausnehmung 36 auf. In diese Ausnehmung greift ein innerer Rastarm 8 mit seinem abgewinkelten Ende ein. Dieser innere Rastarm 8, der auch als Bügel ausgefuhrt sein kann, ist mit einer durch das Gehäuse 6 dicht hindurchgeführten Welle 7 drehfest verbunden.In the embodiment according to FIGS. 2 to 4, when the binding is ready for operation, a pawl-like inner lever 10 rests on the fallen hinged anchor 11. This inner lever 10 is held pivotably about an axis 34 held in the housing 6 and is biased against its unlocked position by means of a weak spring 35. This inner lever 10 has an open edge 36. An inner locking arm 8 engages in this recess with its angled end. This inner locking arm 8, which can also be designed as a bracket, is rotatably connected to a shaft 7 which is tightly guided through the housing 6.

An dieser Welle 7 ist außerhalb des Gehäuses 6 ein äußerer Rastarm 22, der aus Gründen eines reibungsarmen Aufbaues als Rollenhebel ausgebildet ist, drehfest gehalten. Dieser äußere Rastarm 22 stützt im betriebsbereiten Zustand der Bindung einen, um die mit der Bindungsplatte 1 starr verbundene weitere Drehachse 29 schwenkbaren, als Stützglied gestalteten äußeren Stützhebel 21 ab, der als Widerlager für die Spannfeder 19 dient, die den äußeren Rasthebel 18, wie bereits erläutert wurde, gegen die Rastnase 16 des Fersenbackens 17 preßt.On this shaft 7, outside the housing 6, an outer latch arm 22, which is designed as a roller lever for reasons of low friction, is held in a rotationally fixed manner. This outer latch arm 22 supports one in the operational state of the binding, which can be pivoted about the further rotational axis 29 rigidly connected to the binding plate 1 and is designed as a support member, which serves as an abutment for the tension spring 19 which holds the outer latch lever 18, as already was explained, presses against the locking lug 16 of the heel shoe 17.

Wie in Fig. 2 strichpunktiert angedeutet 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 über den inneren Rastarm 8, der in die Ausnehmung 36 des inneren Hebels 10 eingreift und den inneren Hebel 10, der seinerseits an der Rastfläche 33 des Klappankers 11 abgestützt ist.As indicated by dash-dotted lines in FIG. 2, 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 exert a torque on the outer locking arm 22 , which biases this against its unlocked position. This torque is intercepted via the inner locking arm 8, which engages in the recess 36 of the inner lever 10 and the inner lever 10, which in turn is supported on the locking surface 33 of the hinged armature 11.

Wird der Auslösestift 14 durch Betätigung des Auslöseknopfes 15 gegen den Klappanker 11 gedrückt, oder zieht der Elektromagnet 13 den Klappanker 11 an, wozu aufgrund der schwachen Rückstellfeder 12 und der aufgrund der Habelverhältnisse, sowie der Abstützung mittels Raste auftretenden, nur geringen Reibungskräften, nur kleine Kräfte erforderlich sind, so verliert der innere Hebel 10 seine Abstützung und das auf den äußeren Rastarm 22 einwirkende Drehmoment dreht den inneren Rastarm 8 aus der Ausnehmung 36 hinaus, wodurch der Rastarm 8 seine Stütze verliert. Damit kann sich aber auch der äußere Stützhebel 21 in die in Fig. 3 gezeigte Lage drehen, wodurch die Rolle 18a des äußeren Rasthebls 18 ihre Anpressung gegen die Rastnase 16 des Fersenbackens 17 verliert und dieser nach der Freigabe der Sohle aufgrund der auf diese einwirkenden äußeren Kräfte hochschwenken kann.If the trigger pin 14 is pressed against the hinged armature 11 by actuation of the actuating button 15, or the electromagnet 13 pulls the hinged armature 11, which is due to the weak return spring 12 and the only slight frictional forces that occur due to the habel conditions and the support by means of detent, only small Forces are required, the inner lever 10 loses its support and the torque acting on the outer locking arm 22 rotates the inner locking arm 8 out of the recess 36, whereby the locking arm 8 loses its support. However, this also allows the outer support lever 21 to rotate into the position shown in FIG. 3, as a result of which the roller 18a of the outer latching lever 18 loses its pressure against the latching lug 16 of the heel shoe 17 and this after the release of the sole due to the outer acting on it Can swing up forces.

Beim Hochschwenken des Fersenbackens 17 kommt ein nicht dargestellter Ansatz desselben an einem aus Gründen einer besseren übersichtlichkeit ebenfalls nicht dargestellten Ansatz des äußeren Rastarmes 22 zur Anlage und dreht diesen in seine in Fig. 2 und 4 dargestellte Arbeitsstellung, wobei der Ansatz des äußeren Rastarmes 22 von diesem nach rechts absteht. Dieses Rückdrehen des äußeren Rastarmes 22 bewirkt über die Welle 7 auch ein Rückdrehen des inneren Rastarmes 8, wodurch dieser an der Nase 37 des inneren Hebels 10 zur Anlage kommt und diesen ebenfalls zurückdreht. Dadurch kommt dieser wieder an der Rastfläche 33 des Klappankers 11 zur Anlage, nachdem dieser, nach seinem Abfallen vom Elektromagneten 13 kurz aus seiner Ruhelage abgelenkt wurde, wobei der innere Hebel 10 eine Auflauffläche des Klappankers 11 überstreicht. Damit befindet sich der Backen wieder in seinem einstiegsbereiten Zustand.When swiveling the heel jaw 17, an approach (not shown) of the same comes to rest on an approach of the outer latch arm 22, which is also not shown for reasons of better clarity, and rotates it into its working position shown in FIGS. 2 and 4, the approach of the outer latch arm 22 from protrudes to the right. This turning back of the outer locking arm 22 also causes a turning back of the inner locking arm 8 via the shaft 7, as a result of which this comes to rest on the nose 37 of the inner lever 10 and also rotates it back. As a result, it comes to rest against the latching surface 33 of the hinged anchor 11 after it has been briefly deflected from its rest position by the electromagnet 13 after it has dropped, the inner lever 10 being a run-up surface of the hinged anchor 11 sweeps over. The jaw is now in its ready-to-go condition.

Dieses Zurückdrehen erfordert nur wenig Kraft, da dabei die Spannfeder 19 nur auf die mittels der Koppelstange 20 verbundenen Teile 18, 21 einwirkt und mit diesen ein in sich geschlossenes System bildet. Beim nachfolgenden Niederdrücken des Fersenbackens 17 überdrückt dessen Rastnase 16 den Rasthebel 18, wobei die Spannfeder 19 zusammengedrückt wird. Der Fersenbacken 17 ist damit wieder verriegelt.This turning back requires only little force, since the tension spring 19 only acts on the parts 18, 21 connected by means of the coupling rod 20 and forms a self-contained system with them. When the heel jaw 17 is subsequently pressed down, its catch 16 presses over the catch lever 18, the tension spring 19 being compressed. The heel jaw 17 is locked again.

Die Ausführungsform gemäß Fig. 5 bis 7 unterscheidet sich von jener gemäß Fig. 2 bis 4 im wesentlichen dadurch, daß im Inneren des Gehäuses 6 des Schaltbausteines 44 genügend starke Federn angeordnet sind, um - im Falle einer Entriegelung durch das Anziehen des Elektromagneten 13 oder durch Betätigung des Auslösestiftes 14 mittels das Auslöseknopfes 15 - durch diese Federn eine Drehung der als Steuerglied dienenden Welle 7, auch bei fshlender äußerer Belastung herbeizuführen.The embodiment according to FIGS. 5 to 7 differs from that according to FIGS. 2 to 4 essentially in that sufficiently strong springs are arranged in the interior of the housing 6 of the switching module 44 in order to - in the event of an unlocking by the tightening of the electromagnet 13 or by actuating the trigger pin 14 by means of the trigger button 15 - by means of these springs to bring about a rotation of the shaft 7 serving as a control element, even when the external load is released.

Bei der Ausführungsform gemäß der Fig. 5 bis 7 weist der Klappanker 11 ebenfalls eine Rastfläche 33 auf, an der sich im betriebsbereiten Zustand des Fersenbackens 17 ein innerer Hebel 10 abstützt, der mit der Weile 7 drehfest verbunden ist. An diesem inneren Hebel 10 greift eine innere Auslösefeder 24 an, die ausreichend stark ist, um eine Drehung des inneren Hebels 10 auch unter den außerhalb des Gehäuses 6 angreifenden und eine Drehung hemmenden Kräften sicherzustellen.In the embodiment according to FIGS. 5 to 7, the hinged anchor 11 also has a latching surface 33, on which an inner lever 10, which is connected to the shaft 7 in a rotationally fixed manner, is supported in the operational state of the heel shoe 17. This inner lever 10 is engaged by an inner release spring 24 which is sufficiently strong to ensure rotation of the inner lever 10 even under the forces which act outside the housing 6 and prevent rotation.

Die Welle 7 ist, wie bei der Ausführungsform gemäß Fig. 2 bis 4 erläutert, dicht durch das Gehäuse 6 hindurchgeführt, weist aber bei der Ausführungsform gemäß Fig. 5 bis 7 in dem außerhalb des Gehäuses 6 befindlichen Bereich eine Abflachung 38 auf, die als Drehraste dient.As explained in the embodiment according to FIGS. 2 to 4, the shaft 7 is guided tightly through the housing 6, but in the embodiment according to FIGS. 5 to 7 it has a flattened area 38 in the area outside the housing 6, which as Rotary detent serves.

Diese Rasts der Welle 7 wirkt mit einem äußeren Kurvenhebel 26 zusammen, an dem eine äußere Auslösefeder 25 angreift. An diesem äußeren Kurvenhebel 26, der um die im bindungsfesten Teil des Backens gehaltene, starr mit der Bindungsplatte 1 verbundene Achse 39 schwenkbar gehalten ist, stützt sich mit seiner Rolle 22'a ein als Stützglied ausgebildeter äußerer Rastarm 22' im betriebsbereiten Zustand des Backens ab. Dieser äußere Rastarm 22' ist um die weitere Drehächse 29 schwenkbar gehalten und ist über die Koppelstange 20 mit dem äußeren Rasthebel 18 verbunden. Der außere Rastarm 22 stellt dabei, ebenso wie der äußere Stützhebel 21 gemäß den Fig. 2 bis 4, das bei der Beschreibung der gemeinsamen Merkmale der beiden Ausführungsformen erwähnte Stützglied dar, das mit dem äußeren Rasthebel 18 über die Koppelstange 20 verbunden ist.This detents of the shaft 7 cooperate with an outer cam lever 26, on which an outer release spring 25 engages. On this outer cam lever 26, which is held pivotably about the axis 39 held in the binding-fixed part of the jaw, rigidly connected to the binding plate 1, an outer locking arm 22 'designed as a support member is supported with its roller 22'a in the operational state of the jaw . This outer latch arm 22 'is pivotally held about the further rotary axis 29 and is connected to the outer latch lever 18 via the coupling rod 20. The outer latch arm 22, like the outer support lever 21 according to FIGS. 2 to 4, represents the support member mentioned in the description of the common features of the two embodiments, which is connected to the outer latch lever 18 via the coupling rod 20.

Wird der Klappanker 11 durch eine kurzzeitige Erregung des Elektromagneten 13 oder durch Betätigung des Auslöseknopfes 15 bzw. des Auslösestiftes 14 in Richtung auf den Elektromagneten 13 zu bewegt, so wird der innere Hebel 10 freigegeben und dreht sich aufgrund der Vorspannung durch die innere Auslösefeder 24. Dadurch wird auch die Welle 7 verdreht. Dies führt dazu, daß der an der Welle 7, die mit ihrer Abflachung 38 als. Raste wirkt, abgestützte äußere Kurvenhebel 26 seine Stütze verliert und unter dem Einfluß der äußeren Auslösefeder 25 verdreht wird. Dadurch verliert auch der äußere Rastarm 22' eine Stütze und wird ebenfalls verdreht. Dies führt dazu, daß der mit dem äußeren Rasthebel 18 über die Koppelstange 20 verbunden äußere Rastarm 22', der mit der Spannfeder 19 ein geschlossenes System bildet und dem daher die Halterung durch den äußeren Rastarm 18 fehlt, nach rechts ausweichen kann, so daß der Fersenbacken 17 hochschwenken kann. Dabei nehmen die einzelnen Teile des Verriegelungsmechanismus, insbesondere der innere Hebel 10, der äußere Kurvenhebel 26 der äußere Rastarm 22' und der äußere Rasthebel 18, ihre in Fig. 6 gezeigten Stellungen ein.If the hinged armature 11 is moved towards the electromagnet 13 by a brief excitation of the electromagnet 13 or by actuation of the release button 15 or the release pin 14, the inner lever 10 is released and rotates due to the pretensioning by the inner release spring 24. This also rotates the shaft 7. This leads to the fact that on the shaft 7, with its flat 38 as. Detent acts, supported outer cam lever 26 loses its support and is rotated under the influence of the outer release spring 25. As a result, the outer latch arm 22 'also loses support and is also rotated. This leads to the fact that the outer latch arm 22 'connected to the outer latch lever 18 via the coupling rod 20, which forms a closed system with the tension spring 19 and which therefore lacks the holder by the outer latch arm 18, can dodge to the right, so that the Heel jaws 17 can swing up. The individual parts of the locking mechanism, in particular the inner lever 10, the outer cam lever 26, the outer latch arm 22 'and the outer latch lever 18, assume their positions shown in FIG. 6.

Die Rückstellung der Bindung in den einstiegsbereiten Zustand erfolgt ebenfalls während des Hochschwenkens des Fersenbackens 17, der mit entsprechenden Vorsprungen (die aus Gründen einer besseren übersichtlichkeit nicht dargestellt sind) versehen ist, die mit entsprechenden, ebenfalls nicht dargestellten Ansätzen der Welle 7, des äußeren Kurvenhebels 26 und des äußeren Rastarmes 22' oder des äußeren Rasthebels 18 zusammenwirken und diese Teile beim Hochschwenken mitnehmen.The return of the binding to the ready-to-go condition also takes place during the swiveling of the heel shoe 17, which is provided with corresponding projections (which are not shown for reasons of clarity), with corresponding, also not shown approaches of the shaft 7, the outer cam lever 26 and the outer locking arm 22 'or the outer locking lever 18 cooperate and take these parts with you when swinging up.

Beim nachfolgenden Niederdrücken des Fersenbackens 17 kommt es, wis bei der Ausführungsform gemäß Fig. 2 bis 4, zu einem uberdrücken des äußeren Rasthebels 18 entgegen der Kraft der Spannfeder 19.When the heel jaw 17 is subsequently pressed down, as in the embodiment according to FIGS. 2 to 4, the outer locking lever 18 is overpressed against the force of the tension spring 19.

Aus den Fig. 2a und 5a ist weiters die Anordnung der einzelnen Teile des Verriegelungsmechanismus in Draufsicht erkennbar. Aus diesem Grund wurde in diesen Figuren der Fersenhalter weggelassen. Dabei ist bei der Fig. 2b, die ein Detail des Fig. 2a bzw. 5a in vergrößertem Maßstab darstellt, die Art des dichten Hindurchführens der Welle 7 durch die einzelnen Wände 6a, 6b des Gehäuses 6 besonders gut erkennbar. Es ist eine doppelte Abdichtung vorgesehen, nämlich eine Gummidichtung mit Lippen 6d und ein O-Ring 6e, Die Ausbildung derartiger Abdichtungselemente und deren Anordnung ist für den Fachmann auch ohne weitere Erörterung hinlänglich bekannt.The arrangement of the individual parts of the locking mechanism can also be seen in plan view from FIGS. 2a and 5a. For this reason, the heel holder has been omitted from these figures. 2b, which shows a detail of FIGS. 2a and 5a on an enlarged scale, the type of tight passage of the shaft 7 through the individual walls 6a, 6b of the housing 6 can be seen particularly well. A double seal is provided, namely a rubber seal with lips 6d and an O-ring 6e. The design of such sealing elements and their arrangement is well known to those skilled in the art without further discussion.
