Abstract

The invention relates to an espagnolette lock which is blocked against return, as a result of gear play, by means of a blocking member cooperating with an espagnolette connecting slide and with a rotatable gear element belonging to an espagnolette-actuating gear. In order to develop the lock advantageously in terms of production and use, an arrangement of the blocking member (10) between the paths of movement of a control cam (7', 1') assigned respectively to the connecting slide (7) and to the gear element (1) is provided. Preferably, the blocking member (10) is to be in sliding bearing contact with the control cam (7') of the connecting slide by means of a first blocking nose (18') and in sliding bearing contact by means of a second blocking nose (19') with a control cam (1') formed by a circumferential surface of the rotatable gear element (1). <IMAGE>

Description

Die Erfindung betrifft ein Treibstangenschloß gemäß Gattungsbegriff des Anspruchs 1.The invention relates to an espagnolette lock according to the preamble of claim 1.

Ein Treibstangenschloß der in Rede stehenden Art ist bekannt aus der FR-A-532 125, wobei zwei gegenläufig verlagerbare Treibstangen-Anschlußschieber über Zapfen/Schlitzsteuerung von einem drehbaren Getriebeelement verlagerbar sind. An seiner der Schloßgehäuserückwand zugekehrten Längsflanke besitzt der betreffende Treibstangen-Anschlußschieber eine Sperrausnehmung zum Zusammenwirken mit einem sperrklinkenartigen Sperrhebel. Dieser ist von einer Blattfeder in Richtung seines Eingriffes federbelastet. Sobald der Haken des Sperrhebels mit der Sperrausnehmung des Treibstangen-Anschlußschiebers aufgrund einer Verlagerung desselben fluchtet, kann federbeaufschlagt der Sperrhebel in die Eingriffsstellung treten. Aufgehoben wird diese Sperrstellung durch einen dem drehbaren Getriebeelement zugeordneten, vorstehenden Nocken, welcher aufgrund eines Getriebespiels den Sperrhebel aushebt und danach die Verlagerung der Treibstangen-Anschlußschieber zuläßt.An espagnolette lock of the type in question is known from FR-A-532 125, wherein two oppositely displaceable espagnolette connecting slides can be displaced from a rotatable gear element via pins / slot control. On its longitudinal flank facing the lock housing rear wall, the relevant connecting rod connecting slide has a locking recess for interacting with a pawl-type locking lever. This is spring-loaded by a leaf spring in the direction of its engagement. As soon as the hook of the locking lever is aligned with the locking recess of the connecting rod connecting slide due to a displacement thereof, the locking lever can spring-loaded into the engaged position. This locking position is canceled by a projecting cam assigned to the rotatable gear element, which lifts the locking lever due to a play in the gear mechanism and then permits the displacement of the connecting rod connecting slide.

Weiterhin ist ein Treibstangenschloß aus der deutschen Patentschrift 30 34 764 bekannt, bei welchem mittels des Schließgliedes eines Profilzylinders ein Antriebszahnkranz gedreht wird. Dessen Drehbewegung wird über Abtriebszahnräder auf eine längs der Stulpschiene des Schlosses linear verlagerbare Treibstange übertragen. Letztere erhält ihren Antrieb dabei von einem im Schloßkasten längsgeführten Treibstangen-Anschlußschieber, der mit einer Verzahnung mit dem Abtriebsrad des Treibstangen-Betätigungsgetriebes zusammenwirkt. Die Verzahnung ist bei diesem Schloß einer schwenkbar auf dem Treibstangen-Anschlußschieber angeordneten Zahnstange zugeordnet. Bei einem Lastwechsel in der Übertragung der Antriebsbewegung auf die Treibstange schwenkt die Zahnstange unter Ausbildung eines Getriebespiels in die eine oder andere Richtung aus und kann dabei mit einem Festanschlag des Gehäuses zusammenwirken.Furthermore, an espagnolette lock is known from German Patent 30 34 764, in which a drive sprocket is rotated by means of the locking member of a profile cylinder. Its rotational movement is transmitted via output gearwheels to a drive rod that can be linearly displaced along the faceplate of the lock. The latter receives its drive from a drive rod connecting slide which is longitudinally guided in the lock case and which interacts with a toothing with the driven wheel of the drive rod actuating gear. The gearing is assigned to a pivoted on the connecting rod connecting slide rack in this lock. In the event of a load change in the transmission of the drive movement to the drive rod, the toothed rack swivels out in one direction or the other, forming a play in the gear train, and can thereby interact with a fixed stop of the housing.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, auf eine Federbeaufschlagung des Sperrhebels zu verzichten bei verbesserter Verriegelung des Treibstangen-Anschlußschiebers.Based on this prior art, the invention has for its object to dispense with a spring action on the locking lever with improved locking of the connecting rod connecting slide.

Gelöst wird diese Aufgabe durch die im Patentanspruch 1 angegebene Erfindung.This object is achieved by the invention specified in claim 1.

Die Unteransprüche stellen vorteilhafte Weiterbildungen der Erfindung dar.The subclaims represent advantageous developments of the invention.

Zufolge derartiger Ausgestaltung ist ein gattungsgemäßes Treibstangenschloß von erhöhtem Sicherheitswert angegeben, und zwar im Hinblick auf die Verriegelung des Treibstangen-Anschlußschiebers in der Verriegelungsstellung. Die Anlenkung des Sperrhebels zwischen den Bewegungsbahnen der Steuerkurven in Verbindung mit den zwei Schenkeln des Sperrhebels erlaubt es, auf eine Federbeaufschlagung des Sperrhebels zu verzichten. Es liegt vielmehr eine Zwangssteuerung des Sperrhebels vor. Jeder Schenkel wirkt mit einer der beiden Steuerkurven zusammen, wobei die Steuerkurve des Treibstangen-Anschlußschiebers den Steuernocken ausbildet, der über den Sperrhebel bei Zylinderbetätigung des Getriebes zusammenwirkt mit der Freigabeaussparung des Getriebeelementes. Bei Getriebebetätigung bewegen sich die Steuerkurven relativ zueinander. Zufolge des Getriebespiels ist bei einem Wechsel der Antriebsrichtung ein Freigang des Getriebeelements gegeben, so daß mit dem Wechsel der Antriebsrichtung eine Verschiebung der Phasenlage zwischen den beiden Steuerkurven einhergeht. Jeder Schenkel des Sperrhebels besitzt je eine Sperrnase, welche Sperrnasen in gleitender Anlage zu den Steuerkurven liegen. Die Steuerkurven können dabei Nocken bzw. Aussparungen aufweisen, so daß der Sperrhebel bei Beaufschlagung durch den Nocken zu einer Ausweichbewegung tendiert. Die Phasenlage der beiden Steuerkurven zueinander ist bevorzugt so gewählt, daß bei einer schließzylinderbetätigten Getriebeverlagerung der Sperrhebel mit einer seiner Sperrnasen in eine Aussparung der anderen Steuerkurve eintaucht. Der Nocken wird bevorzugt der dem Treibstangen-Anschlußschieber zugeordneten Steuerkurve angeformt, während die Aussparung bevorzugt von der Umfangsfläche des drehbaren Getriebeelementes ausgebildet wird. Bei einer Getriebeverlagerung zufolge einer direkten Beaufschlagung des Treibstangen-Anschlußschiebers, also bei einem Lastwechsel, ist vorgesehen, daß die Verschwenkbarkeit des Sperrhebels bei der Nockenbeaufschlagung gesperrt ist. Dies wird bevorzugt dadurch realisiert, daß die eine Sperrnase des Sperrhebels mit einem umfangsgrößeren Bereich der Steuerkurve des drehbaren Getriebeelementes zusammenwirkt, so daß infolge der Nockenbeaufschlagung durch den Treibstangen-Anschlußschieber die Getriebeverlagerung gesperrt ist. Das Getriebe kann dadurch entsperrt werden, daß zufolge des Getriebespiels und einer Schließzylinderbetätigung des Treibstangengetriebes die dem drehbaren Getriebeelement zugeordnete Steuerkurve derart verlagert wird, daß der Sperrhebel mit einer seiner Sperrnasen in eine Aussparung eintauchen und somit unter Freigabe der Treibstangenverlagerung nockenbeaufschlagt ausweichen kann. Das Getriebeelement wird bevorzugt von einem Antriebszahnkranz ausgebildet, der eine radiale Aussparung aufweist, in die der Schließbart des Profilzylinders hineinragt.As a result of such a configuration, a generic espagnolette lock of increased security value is specified, specifically with regard to the locking of the espagnolette connecting slide in the locking position. The articulation of the locking lever between the movement paths of the control cams in connection with the two legs of the locking lever makes it possible to dispense with spring loading of the locking lever. Rather, there is a positive control of the locking lever. Each leg interacts with one of the two control cams, the control curve of the connecting rod connecting slide forming the control cam which interacts with the release recess of the transmission element via the locking lever when the transmission is actuated by a cylinder. When the transmission is actuated, the control cams move relative to one another. As a result of the gear play If the drive direction changes, there is free movement of the gear element, so that the change in the drive direction is accompanied by a shift in the phase position between the two control cams. Each leg of the locking lever has a locking lug, which locking lugs are in sliding contact with the control cams. The control cams can have cams or recesses so that the locking lever tends to evade when acted upon by the cam. The phase position of the two control cams with respect to one another is preferably selected such that, in the case of a gear shifting actuated by a lock cylinder, the locking lever with one of its locking lugs dips into a recess in the other control curve. The cam is preferably formed on the control cam assigned to the connecting rod connecting slide, while the recess is preferably formed by the peripheral surface of the rotatable gear element. In the case of a gear shift due to a direct action on the connecting rod connecting slide, that is to say during a load change, it is provided that the pivotability of the locking lever is blocked when the cam is acted on. This is preferably realized in that the one locking lug of the locking lever interacts with a larger area of the control curve of the rotatable gear element, so that the gear shifting is locked due to the action of the cam by the connecting rod connecting slide. The transmission can be unlocked in that, due to the play in the transmission and a lock cylinder actuation of the drive rod transmission, the control cam assigned to the rotatable transmission element is displaced in such a way that the locking lever can dip into one of the recesses with one of its locking lugs and thus avoid cam loading when the drive rod displacement is released. The gear element will preferably formed by a drive sprocket which has a radial recess into which the locking bit of the profile cylinder projects.

Bei Treibstangenschlössern besteht das Problem, daß, insbesondere dann, wenn der Schließbart eines Schließzylinders frei drehbar ist, das Schloß durch direkten Angriff an den Schloßelementen geöffnet werden kann. Beispielsweise lassen sich die meisten Schließzylinder bei eingestecktem Schlüssel frei drehen. Ein derartiges Schloß kann demnach dadurch entriegelt werden, daß die treibstangenbetätigbaren Verriegelungsglieder direkt verlagert werden. Die Verlagerung der Treibstange bewirkt dann eine Verlagerung des Treibstangenanschlußschiebers und zufolge der Getriebekopplung dann eine Rückverlagerung der übrigen Riegelglieder, was die Öffnung des Schlosses zur Folge hat. Dieser Mißstand wird durch eine Rücklaufsperre behoben. Erfindungsgemäß wird hierzu die Verlagerung der Treibstange gesperrt. Der Treibstangenanschlußschieber 7 weist hierzu einen Nocken 11 auf, der mit einem Sperrhebel 10 zusammenwirkt. Ist der Sperrhebel 10 an einer Ausweichbewegung gehindert, da er mit seiner zweiten Sperrnase 19' nicht in eine korrespondierende Aussparung 22 des Zahnkranzes 1 eingreifen kann, so sperrt die Sperrnase 18', welche von der Steuerkurve 21 des Nockens 11 beaufschlagt wird, eine weitere Verlagerung der Treibstange 7.The problem with espagnolette locks is that, particularly when the lock bit of a lock cylinder is freely rotatable, the lock can be opened by directly attacking the lock elements. For example, most locking cylinders can be turned freely when the key is inserted. Such a lock can therefore be unlocked in that the locking rod-actuated locking members are moved directly. The displacement of the drive rod then causes a displacement of the drive rod connecting slide and, as a result of the gear coupling, then a displacement of the other locking members, which results in the opening of the lock. This backlog is remedied by a backstop. According to the invention, the displacement of the drive rod is blocked for this. For this purpose, the connecting rod connecting slide 7 has a cam 11 which interacts with a locking lever 10. If the locking lever 10 is prevented from evading, since its second locking lug 19 'does not engage in a corresponding recess 22 in the ring gear 1 can, the locking lug 18 ', which is acted upon by the control cam 21 of the cam 11, blocks a further displacement of the drive rod 7.

Das Treibstangenschloß wird von einem nicht dargestellten Schließzylinder betätigt, welcher einen Schließbart ausbildet, der in eine Aussparung 16 des Antriebszahnkranzes 1 eintaucht. Das Schloß bildet zur Aufnahme des Schließzylinders eine Einstecköffnung 12 aus. Über Abtriebszahnräder 2,3,4 wird die Drehbewegung des Antriebszahnkranzes 1 auf parallel zur Stulpe 12 im Schoßgehäuse geführte Treibstangenanschlußschieber 5 und 7 übertragen. Die Verzahnung des Letztrades 4 kämmt dabei mit Zahnstangen 6 der Treibstangenanschlußschieber. An die Treibstangenanschlußschieber 5,7 sind unter Ausbildung eines Formschlusses Treibstangen 8 und 9 angekoppelt.The espagnolette lock is actuated by a lock cylinder, not shown, which forms a lock bit which plunges into a recess 16 in the drive ring gear 1. The lock forms an insertion opening 12 for receiving the lock cylinder. Via output gears 2, 3, 4, the rotary movement of the drive sprocket 1 is transmitted to drive rod connecting slides 5 and 7 which are guided parallel to the cuff 12 in the lap housing. The teeth of the last wheel 4 meshes with racks 6 of the connecting rod connecting slide. To the connecting rod connecting slide 5,7 connecting rods 8 and 9 are coupled to form a positive connection.

Das Schloß weist weiter einen getriebebetätigbaren Riegel 13 auf und eine nußbetätigbare bzw. wechselbetätigbare Falle 14, die im Ausführungsbeispiel als Rollenfalle ausgebildet ist. Das Getriebe eines derartigen Schlosses wird im Detail in der Offenlegungsschrift 40 14 046 beschrieben, auf welche an dieser Stelle verwiesen wird.The lock also has a gear-operated bolt 13 and a nut-actuated or interchangeable latch 14, which in the exemplary embodiment is designed as a roller latch. The transmission of such a lock is described in detail in the published patent application 40 14 046, to which reference is made here.

Der Sperrhebel 10 ist um eine ortsfest am Getriebegehäuse angeordnete Achse schwenkbar und weist zwei Schenkel 18,19 auf. Wie insbesondere den Figuren 2 bis 7 zu entnehmen ist, bildet der Schenkel 18 eine Sperrnase 18' aus, welche mit einer Steuerkurve 7' des Anschlußschiebers 7 zusammenwirkt. Der Schenkel 19 des Sperrhebels 10 weist eine Sperrnase 19' auf, die mit Umfangsfläche 1' des Antriebszahnkranzes 1 zusammenwirkt. Die Steuerkurve 7' weist einen Nocken 11 auf, welcher von auflaufschrägenartig ausgebildeten Steuerkurvenabschnitten 17 und 21 gebildet wird. Die Beaufschlagung der Sperrnase 18' durch den Nocken 11 bei einer Liniearverlagerung des Treibstangenanschlußschiebers kann eine Schwenkbewegung des Sperrhebels 10 bewirken, dann nämlich, wenn die Sperrnase 19', welche auf der Umfangssteuerfläche 1' des Antriebszahnkranzes gleitet, in eine der beiden Aussparungen 22,23 eintauchen kann. Liegt dagegen die Sperrnase 19' auf dem durchmessergrößeren Steuerkurvenabschnitt 24 auf, ist eine Schwenkbewegung des Nockens gesperrt und damit auch die Verlagerung der Treibstange 7. Der Steuerkurvenabschnitt (24) wird von einem Flächenabschnitt bzw. einem Umfangsabschnitt der Steuerkurve (1') gebildet.The locking lever 10 is pivotable about an axis arranged fixed on the transmission housing and has two legs 18, 19. As can be seen in particular from FIGS. 2 to 7, the leg 18 forms a locking lug 18 'which cooperates with a control curve 7' of the connecting slide 7. The leg 19 of the locking lever 10 has a locking lug 19 'which cooperates with the peripheral surface 1' of the drive sprocket 1. The control cam 7 'has a cam 11, which is formed by control cam sections 17 and 21 which are designed in the manner of run-up slopes. The action of the locking nose 18 ' by the cam 11 during a linear displacement of the connecting rod connecting slide can cause a pivoting movement of the locking lever 10, namely when the locking lug 19 ', which slides on the peripheral control surface 1' of the drive sprocket, can dip into one of the two cutouts 22, 23. If, on the other hand, the locking lug 19 'rests on the control cam section 24 of larger diameter, a pivoting movement of the cam is blocked and thus also the displacement of the drive rod 7. The control cam section (24) is formed by a surface section or a peripheral section of the control cam (1').

In der in Figur 2 dargestellten Getriebestellung wird der Zahnkranz 1 in Pfeilrichtung durch einen nicht dargestellten Schließzylinder angetrieben. Über die in den Figuren 2 bis 7 nicht dargestellten aber in Figur 1 dargestellten Abtriebszahnräder wird die Drehbewegung auf eine Liniearbewegung der Treibstange 7 übertragen. Die Drehung des Antriebszahnkranzes 1 in Pfeilrichtung bewirkt eine Verlagerung der Treibstange 7 nach oben. In der Getriebestellung in Figur 2 beaufschlagt die Steuerfläche 17 des Nocken 11 die Sperrnase 18' des Schenkels 18 des Sperrhebels 10, welcher um eine ortsfeste Achse 20 schwenkbar gelagert ist. Mit seinem zweiten Schenkel 19 und der von diesem ausgebildeten Sperrnase 19' gleitet der Sperrhebel 10 auf einem durchmessergrößeren Flächenabschnitt 24 der Steuerkurve 1' des Antriebszahnkranzes 1. Die Sperrnase 19' ist in dieser Position im Übergangsbereich zwischen der Steuerkurve 24 und der Aussparung 22, die von einem durchmessergeringeren Steuerkurvenabschnitt ausgebildet wird. Eine minimale weitere Drehung des Antriebszahnkranzes 1 bewirkt, daß die Aussparung 22 in Gegenüberlage tritt zur Sperrnase 19', so daß der Sperrhebel 10 schwenkbar ist.In the gear position shown in Figure 2, the ring gear 1 is driven in the arrow direction by a locking cylinder, not shown. The rotary movement is transferred to a linear movement of the drive rod 7 via the output gearwheels, not shown in FIGS. 2 to 7 but shown in FIG. The rotation of the drive sprocket 1 in the direction of the arrow causes the drive rod 7 to move upward. In the gear position in Figure 2, the control surface 17 of the cam 11 acts on the locking lug 18 'of the leg 18 of the locking lever 10 which is pivotally mounted about a fixed axis 20. With its second leg 19 and the locking lug 19 'formed by this, the locking lever 10 slides on a larger diameter portion 24 of the control cam 1' of the drive sprocket 1. The locking lug 19 'is in this position in the transition region between the control cam 24 and the recess 22, the is formed by a smaller diameter cam section. A minimal further rotation of the drive sprocket 1 causes the recess 22 to face the locking lug 19 ', so that the locking lever 10 is pivotable.

Eine weitere Drehung des Antriebszahnkranzes 1 im Uhrzeigersinn (Fig. 3) bewirkt eine weitere Treibstangenverlagerung nach oben, wobei dann zufolge der Nockenbeaufschlagung der Schwenkhebel 10 unter Durchführung der Verschwenkung ausweicht und mit seiner Sperrnase 19' in die Aussparung 22 eintaucht und somit den Weg zum Passieren des Nockens 11 vorbei an der Sperrnase 18' freigibt.A further rotation of the drive sprocket 1 clockwise (Fig. 3) causes a further shifting of the connecting rod upwards, then, according to the cam action, the pivot lever 10 dodges while performing the pivoting and dips with its locking lug 19 'into the recess 22 and thus clears the way for passing the cam 11 past the locking lug 18'.

In den Figuren 3 und 4 ist die verschwenkte Stellung des Schwenkhebels 10 bei der Passierung des Nockens 11 vorbei an der Sperrnase 18' dargestellt. Figur 4 ist eine Bewegungsfolgedarstellung nach einer weiteren Drehung des Antriebszahnkranzes in Uhrzeigerrichtung, ausgehend von einer Getriebestellung gemäß Figur 3. Die Länge der Aussparung 22,23 ist so gewählt, daß der Schwenkhebel, nachdem der Nocken 11 die Sperrnase 18' passiert hat, wieder in seine Ausgangslage zurückgeschwenkt wird. Hierbei wird die Nase 19' des Sperrhebels 10 von einem Übergangsbereich zwischen der Aussparung 23 und dem Steuerkurvenabschnitt 24 beaufschlagt.FIGS. 3 and 4 show the pivoted position of the pivot lever 10 as it passes the cam 11 past the locking lug 18 '. Figure 4 is a movement sequence representation after a further rotation of the drive sprocket in the clockwise direction, starting from a gear position according to Figure 3. The length of the recess 22,23 is selected so that the pivot lever after the cam 11 has passed the locking lug 18 'in again its starting position is pivoted back. Here, the nose 19 'of the locking lever 10 is acted upon by a transition region between the recess 23 and the control curve section 24.

In Figur 5 ist eine Getriebestellung dargestellt nach dem Passieren des Nockens 11 vorbei an der Sperrnase 18'. Der Sperrhebel 10 ist zufolge einer weiteren Drehung des Antriebszahnkranzes in Uhrzeigerrichtung wieder zurückverschwenkt und gleitet nun mit seiner Sperrnase 18' auf dem linearen Abschnitt der Steuerkurve 7' des Treibstangenanschlußschiebers 7 auf. Bei einer weiteren, nicht dargestellten Getriebeverlagerung, verursacht durch eine weitere Drehung des Antriebszahnkranzes im Uhrzeigersinn erfolgt eine weitere Verlagerung des Treibstangenanschlußschiebers nach oben, wobei der Sperrhebel 10 in der in Figur 5 dargestellten Schwenklage bleibt und mit der Sperrnase 18' auf der Steuerkurve 7' aufgleitet.5 shows a gear position after passing the cam 11 past the locking lug 18 '. The locking lever 10 is pivoted back again after a further rotation of the drive sprocket in the clockwise direction and now slides with its locking lug 18 'on the linear portion of the cam 7' of the connecting rod connecting slide 7. In a further gear shift, not shown, caused by a further rotation of the drive sprocket in a clockwise direction, the drive rod connecting slide is shifted further upwards, the locking lever 10 remaining in the pivoted position shown in FIG. 5 and sliding with the locking lug 18 'on the control cam 7' .

Erfolgt ausgehend aus einer derartigen, zuletzt beschriebenen Getriebestellung eine Beaufschlagung auf den Treibstangenanschlußschieber nach unten, und kann sich der Antriebszahnkranz frei drehen, so tritt zufolge des Lastwechsels eine Rückverlagerung des Treibstangengetriebes ein. Die Rückverlagerung bewirkt zunächst, daß die Treibstange sich nach unten bewegt, und der Zahnkranz 1 entsprechend im Gegenuhrzeigersinn gedreht wird. Zufolge des Getriebefreiganges zwischen dem Antriebszahnkranz und dem Treibstangenanschlußschiebers hat sich die Phasenlage der beiden Steuerkurven 1',7' verändert. Der Getriebefreigang wird dadurch bewirkt, daß die Vielzahl der Zahnräder des Treibstangenantriebsgetriebes mit Spiel ineinander greifen. Die zuvor beschriebene Abwärtsverlagerung des Treibstangenanschlußschiebers 7 erfolgt ungestört so lange, bis die Steuerfläche 21 des Nockens 11 die Sperrnase 18 des Sperrhebels 10 beaufschlagt (Figur 6). Zufolge des Freiganges und der durch den Lastwechsel einhergegangenen Phasenverschiebung zwischen den beiden Steuerkurven beaufschlagt der Schwenkhebel mit seiner Sperrnase 19' in dieser Getriebestellung den durchmessergrößeren Umfangsabschnitt 24 der Steuerkurve 1' und kann demzufolge keine Verschwenkung durchführen. Eine Weiterverlagerung des Treibstangenanschlußschiebers 7 nach unten ist somit blockiert.If, starting from such a gearbox position, as described last, the drive rod connecting slide is acted upon downwards and the drive sprocket can rotate freely, the drive rod gearbox is shifted back as a result of the load change. The backward displacement initially causes the drive rod to move downward, and the ring gear 1 is accordingly rotated counterclockwise. As a result of the transmission clearance between the drive sprocket and the connecting rod connecting slide, the phase position of the two control cams 1 ', 7' has changed. The transmission clearance is brought about by the fact that the plurality of gearwheels of the drive rod drive transmission mesh with one another with play. The above-described downward displacement of the connecting rod connecting slide 7 takes place undisturbed until the control surface 21 of the cam 11 acts on the locking lug 18 of the locking lever 10 (FIG. 6). As a result of the free passage and the phase shift between the two control cams caused by the load change, the pivoting lever with its locking lug 19 'acts on the larger-diameter peripheral section 24 of the control curve 1' in this gear position and, consequently, cannot carry out any pivoting. A further shifting of the connecting rod connecting slide 7 downward is thus blocked.

Eine aus dieser Getriebestellung heraus erfolgende schließzylinderbetätigte Getriebeverlagerung, wobei der Antriebszahnkranz in Pfeilrichtung in Figur 7, also gegen dem Uhrzeigersinn gedreht wird, ermöglicht zufolge des Freigangs eine minimale Verlagerung des Antriebszahnkranzes 1, ohne daß sich der Treibstangenanschlußschieber 7 weiter nach unten zu verlagern braucht. Durch diese minimale Verdrehung des Antriebszahnkranzes wird der Übergangsbereich zwischen der Steuerkurve 24 und der Aussparung 23 unter der Sperrnase 19' hinwegbewegt, so daß bei einer weiteren Verdrehung des Antriebszahnkranzes entgegen Uhrzeigersinn, einhergehend mit einer Abwärtsverlagerung des Treibstangenanschlußschiebers 7 die Sperrnase 19' in die Aussparung 23 eintauchen. Durch diese Schwenkbewegung des Sperrhebels 10 vollführt die Sperrnase 18' nockenbeaufschlagt eine Ausweichbewegung, so daß der Nocken 11 an der Sperrnase 18' vorbei sich nach unten verlagern kann. Die Sperrwirkung ist demzufolge durch eine Schließbetätigung des Treibstangenschlosses aufgehoben.A lock cylinder-actuated gear shift from this gear position, the drive sprocket being rotated in the direction of the arrow in FIG. 7, that is to say counterclockwise, enables the drive sprocket 1 to be displaced minimally without having to move the connecting rod connecting slide 7 further downward. Due to this minimal rotation of the drive sprocket, the transition area between the control cam 24 and the Recess 23 moves under the locking lug 19 ', so that when the drive sprocket is turned further counterclockwise, accompanied by a downward displacement of the connecting rod connecting slide 7, the locking lug 19' plunges into the recess 23. This pivoting movement of the locking lever 10 causes the locking lug 18 'to perform an evasive movement, so that the cam 11 can move downward past the locking lug 18'. The locking effect is therefore canceled by a closing operation of the espagnolette lock.

In Figur 8 ist dargestellt, daß die Steuerkurve 1' parallel zur Verzahnung 25 des Zahnkranzes 1 angeordnet ist. Die Beabstandung der beiden Steuerkurven zueinander ist so gewählt, daß die Sperrnase 18' gleitend auf der Steuerkurve 7' aufliegt und gleichzeitig die Sperrnase 19' gleitend auf der Steuerkurve 1' aufliegt. Die Hebelverhältnisse, d.h. die Länge der Schenkel 18 und 19 des Sperrhebels 10 sind so gewählt, daß ein Eintauchen der Sperrnase 19' in die Aussparung 22 bzw. 23 eine Verlagerung der Sperrnase 18' bewirkt, die der Höhe des Nocken 11 entspricht. Es ist vorgesehen, daß bei weiterer Drehung des Antriebszahnkranzes 1 ausgehend aus einer Getriebestellung gemäß Figur 4 im Uhrzeigersinn der Sperrhebel 10 keine weitere Verschwenkung mehr durchführt, so daß die Sperrnase 19' beim nochmaligen Passieren der Aussparung 22 oder 23 nicht in gleitender Auflage auf der Steuerkurve 1' aufliegt, sondern um den Betrag der Tiefe der Aussparung 22,23 von der Steuerkurve beabstandet ist.FIG. 8 shows that the control cam 1 'is arranged parallel to the toothing 25 of the ring gear 1. The spacing of the two control cams from one another is selected such that the locking lug 18 'slides on the control cam 7' and at the same time the locking lug 19 'slides on the control curve 1'. The leverage ratios, i.e. the length of the legs 18 and 19 of the locking lever 10 are chosen so that immersion of the locking lug 19 'in the recess 22 or 23 causes a displacement of the locking lug 18', which corresponds to the height of the cam 11. It is provided that when the drive sprocket 1 rotates further from the gear position according to FIG. 4 clockwise, the locking lever 10 no longer pivots, so that the locking lug 19 'does not slide on the control cam when it passes through the recess 22 or 23 again 1 'rests, but is spaced from the control curve by the amount of the depth of the cutout 22, 23.

Der Hebelarm 18 des Hebels 10 ist länger ausgebildet als der Hebelarm 19. Demzufolge hat der Nocken 11 eine größere Höhe, als die Tiefe der Aussparung 22,23 gegenüber dem Umfangsbereich 24. Der Gebtriebefreigang zwischen dem Antriebszahnkranz und dem Treibstangenanschlußschieber ist so gewählt, daß bei einer Nockenbeaufschlagung der Sperrnase 18' durch den Nocken 11 ein übergangsbereich zwischen der Aussparung 22 und dem erhabenen Umfangsbereich 24 des Antriebszahnkranzes 1 an der Sperrnase 19' durch Schließzylinderbetätigung vorbeigeführt werden kann, ohne daß sich die Treibstange 7 verlagert. Bei einer Getriebebeaufschlagung seitens des Treibstangenanschlußschiebers 7 ist vorgesehen, daß die Sperrnase 19' gegen den Endbereich der erhabenen Umfangsfläche 24 stößt (Fiqur 6). Die Rücklaufsperre des Treibstangenschlosses kann mittels des Freiganges des Getriebeelementes gegenüber dem Treibstangenanschlußschieber durch einen Wechsel der Antriebsrichtung des Getriebeelementes 1 bzw. eines Lastwechsels im Getriebe gesperrt werden. Durch den zufolge des Getriebespieles vorhandenen Freigang erfolgt eine Änderung der Phasenlase der beiden Steuerkurven 7',1' und damit eine Beeinflussung der Verlagerbarkeit des zwischen den Bewegungsbahnen von Anschlußschieber 7 und Getriebeelement 1 angeordneten Sperrgliedes 10.The lever arm 18 of the lever 10 is longer than the lever arm 19. Accordingly, the cam 11 has a greater height than the depth of the recess 22, 23 opposite the peripheral area 24. The gear clearance between the drive sprocket and the connecting rod connecting slide is selected so that when the locking lug 18 'is acted upon by the cam 11, a transition area between the recess 22 and the raised peripheral area 24 of the driving sprocket 1 leads past the locking lug 19' by actuating the lock cylinder can be moved without the drive rod 7. In the case of a transmission action on the part of the connecting rod connecting slide 7, it is provided that the locking lug 19 ′ abuts against the end region of the raised peripheral surface 24 (FIG. 6). The backstop of the espagnolette lock can be blocked by changing the drive direction of the gear element 1 or a load change in the gearbox by means of the free passage of the gear element relative to the power rod connecting slide. As a result of the clearance available as a result of the gear play, there is a change in the phase relief of the two control cams 7 ', 1' and thus an influence on the displaceability of the locking member 10 arranged between the movement paths of the connecting slide 7 and gear element 1.
