Abstract

A lock for a door has a housing with an opening, a latch bolt and a further latch bolt both mounted to the housing for parallel displacement relative to the housing. A latch follower formed as part of a latch is connected to the latch bolt as is a changer, with the parallel displacement occurring due to the action of one of the latch follower via the latch and the changer via a key. A lock cylinder is situated in the housing opening. Two drive rods and associated control plates are provided along and a changer lever hinged to one of the control plates and connected to the lock cylinder. The lock cylinder can drive the changer via the changer lever and its hinged control plate. One side of the lock has, therefore, two drive rods.

Description

Die Erfindung betrifft ein Schloß, insbesondere ein Einsteckschloß für eine Außentür, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a lock, in particular a mortise lock for an outer door, according to the preamble of claim 1.

Derartige Schlösser finden bei Haustüren oder Wohnungseingangstüren Verwendung, wobei sie bei der gebräuchlichsten Ausbildung als Einsteckschloß in eine Schloßtasche des Türblatts eingeschoben und über einen stirnseitig angebrachten Stulp oder dergleichen im Türblatt gehalten werden. Nach dem Anbringen dieses Einsteckschlosses an der Tür werden noch der oder die Türdrücker und ein Schließzylinder montiert. Im Falle einer Außentür befindet sich ein Türdrücker normalerweise nur an der Innenseite, während gegenüberliegend an der Außenseite ein sogenannter Knauf, d.h. ein nicht betätigbarer Griff montiert ist. Mit Hilfe des drehbaren Türdrückers kann die Falle zurückgezogen werden. Wenn sich der Riegel in seiner zurückgeschlossenen Stellung befindet, kann man bei zurückgezogener Falle die Tür öffnen. Sofern außen kein Türdrücker angebracht ist, läßt sich die Tür von außen nur mit Hilfe eines Schlüssels öffnen, über welchen die Falle ebenfalls zurückziehbar ist. Desweiteren läßt sich mit Hilfe des Schlüssels der Riegel sowohl von außen als auch von innen sowohl vorschließen als auch zurückschließen.Locks of this type are used in front doors or apartment entrance doors, and in the most common configuration they are inserted as a mortise lock into a lock pocket in the door leaf and are held in the door leaf via a faceplate or the like attached to the front. After attaching this mortise lock the door handle (s) and a locking cylinder are also mounted on the door. In the case of an outer door, a lever handle is normally only on the inside, while a so-called knob, ie a handle that cannot be actuated, is mounted opposite on the outside. The latch can be pulled back with the help of the rotating door handle. When the bolt is in its closed position, the door can be opened when the latch is retracted. If there is no door handle attached to the outside, the door can only be opened from the outside using a key with which the latch can also be withdrawn. Furthermore, with the help of the key, the bolt can be both closed and closed both from the outside and from the inside.

Es sind auch Schlösser bekannt, welche nicht nur im Bereich des Schlosses oder Schloßkastens gegenüber dem festen Rahmen verriegelt werden, sondern mit Hilfe zusätzlicher Verriegelungseinrichtungen auch unterhalb und/oder oberhalb des eigentliches Schlosses bzw. des Schloßkastens. Diese in Zusatzriegelkästen vorgesehene Verriegelungseinrichtungen müssen gleichzeitig mit dem Riegel betätigbar sein, also in eine wirksame Stellung gebracht oder aus dieser in eine wirkungslose Stellung zurückgeführt werden können. Es sind desweiteren Schlösser bekannt, bei denen man den Riegel über den drehbaren Türdrücker in eine wirksame Stellung bzw. aus dieser in die Freigabestellung bringen kann, wobei der Drücker selbstverständlich auch hierbei zur Fallenbetätigung dient. Solche Schlösser gibt es sowohl mit als auch ohne zusätzliche Verriegelungseinrichtungen entlang zumindest der Schloßseite der Tür.Locks are also known which are not only locked in the area of the lock or lock case with respect to the fixed frame, but also with the aid of additional locking devices below and / or above the actual lock or lock case. These locking devices provided in additional locking boxes must be operable at the same time as the bolt, that is to say they can be brought into an effective position or be returned from this to an ineffective position. Locks are also known in which the bolt can be brought into an effective position or out of this into the release position via the rotatable door handle, the handle being Of course, this also serves to operate the latch. Such locks exist both with and without additional locking devices along at least the lock side of the door.

Aus der DE 35 03 466 A1 ist ein Zusatzriegelkasten bekannt geworden, welcher über eine Treibstange vom Hauptschloß antreibbar ist. Dieses Hauptschloß kann z.B. gemäß der EP 575 701 A1 ausgebildet sein. Bei einer derartigen Verriegelungseinrichtung wird der Riegel mittels des Schließzylinders ausgeschlossen und zurückgeschlossen. Als nachteilig hat sich jedoch herausgestellt, daß bei einem Öffnen der Tür z.B. durch Betätigen des Türdrückers nicht nur die Falle sondern auch der Riegel des Zusatzriegelkastens betätigt und in die Freigabestellung verlagert werden, so daß die Tür geöffnet werden kann. Es kann also kein vorschnelles Öffnen der Tür, beispielsweise durch Kleinkinder, vermieden werden, so daß ungebetene Personen unmittelbar Zutritt haben.From DE 35 03 466 A1 an additional bolt box has become known which can be driven from the main lock via a drive rod. This main lock can e.g. be designed according to EP 575 701 A1. In such a locking device, the bolt is excluded and closed by means of the locking cylinder. It has been found to be disadvantageous that when the door is opened e.g. by actuating the door handle not only the latch but also the bolt of the additional bolt box are actuated and moved to the release position so that the door can be opened. It is therefore not possible to avoid opening the door prematurely, for example by small children, so that uninvited persons have direct access.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Schließeinrichtung der eingangs genannten Art derart weiterzubilden, daß auch beim Öffnen der Tür mittels Betätigung des Hauptschloßkastens noch eine gewisse Sicherheit gegen vollständiges Öffnen gewährleistet ist.The invention is therefore based on the object of developing a locking device of the type mentioned in such a way that even when the door is opened, a certain security against complete opening is still ensured by actuating the main lock case.

Diese Aufgabe wird bei einem Schloß der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß zusätzlich zum Wechsel ein Wechselhebel vorgesehen ist, daß der Wechselhebel an einer zweiten Steuerplatte angelenkt ist und daß die Steuerplatte mit einer zweiten Treibstange z.B. für ein Sperrschwenkbügelschloß verbunden ist.This object is achieved according to the invention in a castle of the type mentioned in that in addition to a change Change lever is provided that the change lever is articulated on a second control plate and that the control plate is connected to a second drive rod, for example for a locking swivel lock.

Beim erfindungsgemäßen Schloß kann zusätzlich zu den Zusatzriegelkästen z.B. noch ein Sperrschwenkbügelschloß vorgesehen sein, welches über eine zweite Treibstange betätigt wird. Diese zweite Treibstange wird von einer zweiten Steuerplatte angesteuert, die im Hauptschloß vorgesehen ist. Diese zweite Steuerplatte wird ihrerseits von einem Wechselhebel betätigt, der mit dem Wechsel verbunden ist. Auf diese Weise werden die Zusatzriegelkästen und das Sperrschwenkbügelschloß unabhängig voneinander mittels zweier Treibstangen betätigt. Auf diese Weise können die Zusatzriegelkästen so angesteuert werden, daß diese zusammen mit dem Hauptschloß öffnen, wohingegen das Sperrschwenkbügelschloß nach wie vor seine Sperrlage beibehält, d.h. der Sperriegel in seiner vorgeschlossenen Lage verbleibt. Erst durch separate Ansteuerung der zweiten Treibstange oder des Sperriegels über dessen Drehknauf wird dieser Riegel zurückgeschlossen, so daß die Tür vollständig geöffnet werden kann.In the lock according to the invention, in addition to the additional bolt boxes, e.g. a locking swivel lock can be provided, which is actuated via a second drive rod. This second drive rod is controlled by a second control plate, which is provided in the main lock. This second control plate is in turn actuated by a change lever which is connected to the change. In this way, the additional bolt boxes and the locking swivel lock are operated independently of one another by means of two connecting rods. In this way, the additional bolt boxes can be controlled so that they open together with the main lock, whereas the locking swivel lock still maintains its locked position, i.e. the locking bolt remains in its pre-closed position. Only by separately controlling the second drive rod or the locking bolt via its rotary knob is this bolt closed so that the door can be opened completely.

Über den Steuernocken können sowohl der Wechsel als auch der Wechselhebel angesteuert werden.Both the change and the change lever can be controlled via the control cam.

Mit der erfindungsgemäßen Verriegelungseinrichtung kann die Tür zwar einen Spalt weit geöffnet werden, ein vollständiges Aufschwenken wird jedoch verhindert. Auf diese Weise wird auch ein versehentliches komplettes Öffnen bzw. Entriegeln der Tür verhindert.With the locking device according to the invention, the door can be opened slightly, but it is prevented from swinging open completely. This also prevents accidental complete opening or unlocking of the door.

Bei einer Weiterbildung ist vorgesehen, daß der Wechselhebel mit dem Wechsel verbunden, insbesondere über eine Zapfen-Langloch-Verbindung mit dem gekoppelt ist. Diese Zapfen-Langloch-Verbindung erlaubt Relativbewegungen zwischen dem Wechselhebel und dem Hebel, so daß die Betätigung des einen nicht unmittelbar eine Betätigung des anderen verursachen muß.In a further development it is provided that the change lever is connected to the change, in particular is coupled to it via a pin-elongated hole connection. This pin-elongated hole connection allows relative movements between the change lever and the lever, so that the actuation of one does not have to directly actuate the other.

Gemäß einem bevorzugten Ausführungsbeispiel ist der Wechselhebel mit einem Langloch versehen, in welches ein Zapfen des Wechsels eingreift. Dabei liegt in der Ruhelage des Schlosses der Zapfen am einen Ende des Langloches an. Wird also der Wechselhebel in die eine Richtung bewegt, dann wird über den anliegenden Zapfen der Wechsel mitgenommen. Wird jedoch der Wechsel in die gleiche Richtung bewegt, dann läuft der zapfen frei im Langloch, ohne daß der Wechselhebel betätigt wird.According to a preferred embodiment, the change lever is provided with an elongated hole in which a pin of the change engages. In the rest position of the lock, the pin rests on one end of the elongated hole. So if the change lever is moved in one direction, the change is taken along via the adjacent pin. However, if the change is moved in the same direction, the pin runs freely in the slot without the change lever being actuated.

Ein bevorzugtes Ausführungsbeispiel sieht vor, daß der Wechselhebel eine Steuerkante aufweist, an der ein Steuernocken eines mittels des Schließzylinders betätigbaren Getriebes, insbesondere eines Planetengetriebes angreift. Über dieses Planetengetriebe, welches durch Drehen eines Schlüssels betätigt wird, wird also der Wechselhebel im Schloß verlagert und dadurch die zweite Treibstange bewegt. Außerdem wird über den Wechselhebel der Wechsel betätigt, so daß über diesen die Falle eingezogen wird. Die Tür kann also von außen durch Betätigung eines Schlüssels geöffnet werden, wobei alle Schlösser in ihre Offenstellung bewegt werden.A preferred exemplary embodiment provides that the change lever has a control edge on which a control cam of a gear, which can be actuated by means of the locking cylinder, acts, in particular a planetary gear. over this planetary gear, which is actuated by turning a key, the shift lever is thus shifted in the lock and thereby moves the second drive rod. In addition, the change is actuated via the change lever, so that the trap is drawn in via this. The door can thus be opened from the outside by actuating a key, with all the locks being moved into their open position.

Die Zapfen-Langloch-Verbindung des Wechselhebels und des Wechsels ist so gewählt, daß beim Betätigen des Wechselhebels der Wechsel angetrieben wird, wohingegen beim Betätigen des Wechsels mittels der Drückernuß der Wechselhebel abgekoppelt ist. Ein Zurückschließen des Riegels des Sperrschwenkbügelschlosses ist also mittels des Drückers ausgeschlossen.The pin-slot connection of the change lever and the change is selected so that when the change lever is actuated the change is driven, whereas when the change is actuated by means of the follower the change lever is uncoupled. A closing of the bolt of the locking swivel bracket lock is therefore excluded by means of the handle.

In bekannter Art und Weise ist der Wechselhebel über eine Kulisse in einer ersten Steuerplatte geführt und ist aus dem Wirkbereich eines Planetengetriebes herauslenkbar. Auf diese Weise wird er erst beim Einziehen der Falle, jedoch nicht beim Zurückschließen des Riegels der Wechselhebel vom Planetengetriebe betätigt.In a known manner, the change lever is guided over a link in a first control plate and can be deflected out of the effective range of a planetary gear. In this way, it is only actuated by the planetary gear when the latch is pulled in, but not when the bolt is closed.

Als vorteilhaft wird angesehen, daß die zweite Steuerplatte in Richtung der zweiten Treibstange im Schloß verschiebbar gelagert ist. Die zweite Steuerplatte erstreckt sich parallel zur ersten Steuerplatte und besitzt lediglich die Funktion des Antriebs der zweiten Treibstange.It is considered advantageous that the second control plate is slidably mounted in the direction of the second drive rod in the lock. The second control plate extends in parallel to the first control plate and only has the function of driving the second drive rod.

Weitere Vorteile, Merkmale und Einzelheiten ergeben sich aus den Unteransprüchen sowie aus der nachfolgenden Beschreibung, in der unter Bezugnahme auf die Zeichnung ein besonders bevorzugtes Ausführungsbeispiel im einzelnen dargestellt ist. Dabei zeigen:

Further advantages, features and details emerge from the subclaims and from the following description, in which a particularly preferred exemplary embodiment is shown in detail with reference to the drawing. Show:
Figure 1
a plan view of a mortise lock according to the invention in the rest position and the cover removed;
Figure 2
a plan view of Figure 1 with the lock cylinder operated; and
Figure 3
a plan view of Figure 1 with actuated follower.

In der Figur 1 ist in Draufsicht ein insgesamt mit 1 bezeichnetes Haupt- oder Schloßgehäuse dargestellt, welches auf der dem Betrachter zugewandten Seite mittels eines abgenommenen und daher in der Zeichnung nicht dargestellten Deckels verschlossen ist. Im Gehäuseinneren sind eine Falle 2 und ein Riegel 3 im Sinne des Doppelpfeils 4 verschiebbar. Außerdem ist im Schloßgehäuse 1 eine Drückernuß 5 im Sinne des Doppelpfeils 6 drehbar gelagert. Sie besitzt einen Durchbruch 7, insbesondere einen Vierkantdurchbruch, zur Aufnahme eines Vierkantdorns eines Drückers oder anderen Betätigungselements für die Falle 2. Ein radial vorstehender Ansatz 8 der Drückernuß 5 liegt am oberen Ende eines verschiebbaren Zwischenstücks 10 an, dessen unteres Ende dem oberen Ende einer Rückstellfeder (nicht dargestellt) zugeordnet ist. Es handelt sich dabei um eine Schraubendruckfeder, die mit ihrem oberen Ende in einem Federgehäuse gehalten ist. Wenn man also die Drückernuß 5 im Sinne des Pfeiles 13 dreht, so bewirkt dies einerseits ein Zusammenpressen der Rückstellfeder und andererseits ein Zurückziehen der Falle 2 im Sinne des Pfeils 14. Man erreicht dies dadurch, daß ein weiterer radial vorstehender Ansatz 15 der Drücknuß 5 an einem zapfenartigen Vorsprung 16 einer Steuernußscheibe 17 anliegt oder anlegbar ist, welche an der Drückernuß 5 drehbar gelagert ist. Das beispielsweise in Figur 1 nach oben weisende Ende 18 der Steuernußscheibe 17 liegt an einer Schulter 19 des inneren Endes der Falle 2 bzw. des Fallenschwanzes 20 an.FIG. 1 shows a top view of a main or lock housing, generally designated 1, which is closed on the side facing the viewer by means of a removed cover and therefore not shown in the drawing. A trap 2 and a bolt 3 can be moved in the direction of the double arrow 4 inside the housing. In addition, a follower 5 is rotatably mounted in the sense of the double arrow 6 in the lock housing 1. It has an opening 7, in particular a square opening, for receiving one Square mandrel of a pusher or other actuating element for the latch 2. A radially projecting extension 8 of the pusher nut 5 lies against the upper end of a displaceable intermediate piece 10, the lower end of which is assigned to the upper end of a return spring (not shown). It is a helical compression spring that is held with its upper end in a spring housing. So if you turn the follower 5 in the direction of arrow 13, this causes, on the one hand, a compression of the return spring and, on the other hand, a retraction of the latch 2 in the direction of arrow 14. This is achieved by a further radially projecting extension 15 of the presser nut 5 a peg-like projection 16 of a control nut disk 17 bears or can be put on, which is rotatably mounted on the trigger nut 5. The upward-facing end 18 of the control nut disk 17, for example in FIG. 1, bears on a shoulder 19 of the inner end of the latch 2 or latch tail 20.

In einen Durchbruch 21 am Boden des Schloßgehäuses 1 sowie am nicht dargestellten Schloßdeckel ist ein Schließzylinder 22 bekannter Bauart, beispielsweise ein Profilzylinder eingesetzt. Dieser Schließzylinder 22 wird mit Hilfe eines in den Schließzylinder 22 eingesteckten Schlüssels 36 im Sinne des Doppelpfeils 24 um die geometrische Achse 45 gedreht und bewirkt über ein zwischengeschaltetes Getriebe, insbesondere ein Planetengetriebe 44 die Verdrehung eines Zahnrades 23 und dadurch ein Ausschieben bzw. Zurückziehen des Riegels 3. Der nicht dargestellte Schließbart des Schließzylinders 22 treibt bei dieser Ausführungsform in bekannter Weise einen geschlitzten Zahnkranz an. Dessen Drehbewegung wird über zwei Zwischenräder auf das Zahnrad 23 übertragen. Dieses treibt in bekannter Weise eine erste Steuerplatte 25 an, über welche erste Treibstangen 42 und 43 nach oben bzw. nach unten angetrieben werden.In a breakthrough 21 on the bottom of the lock housing 1 and on the lock cover, not shown, a lock cylinder 22 of a known type, for example a profile cylinder, is used. This lock cylinder 22 is rotated with the aid of a key 36 inserted into the lock cylinder 22 in the sense of the double arrow 24 about the geometric axis 45 and, via an intermediate gear, in particular a planetary gear 44, causes the rotation of a toothed wheel 23 and thereby an extension or retraction of the bolt 3. The In this embodiment, the lock bit of the lock cylinder 22, not shown, drives a slotted ring gear in a known manner. Its rotational movement is transmitted to the gear 23 via two intermediate gears. This drives a first control plate 25 in a known manner, via which first drive rods 42 and 43 are driven up and down.

Das Zahnrad 23 trägt auf seiner dem Betrachter zugewandten Stirnseite einen Steuernocken 26, der beim Verdrehen des Zahnrades 23 eine Steuerkante 27 eines Wechselhebels 28 antreibt. Dieser Wechselhebel 28 ist über einen Zapfen 29 in einer Kulisse 30, die in der ersten Steuerplatte 25 vorgesehen ist, geführt und mittels eines Zapfens 31 an einer zweiten Steuerplatte 32 gelenkig festgelegt. Diese zweite Steuerplatte 32 ist in Richtung des Doppelpfeils 9 verschieblich im Schloßgehäuse 1 gelagert.The gear 23 carries on its end facing the viewer a control cam 26 which drives a control edge 27 of a change lever 28 when the gear 23 is rotated. This change lever 28 is guided via a pin 29 in a link 30, which is provided in the first control plate 25, and articulated by means of a pin 31 on a second control plate 32. This second control plate 32 is slidably mounted in the lock housing 1 in the direction of the double arrow 9.

Am Wechselhebel 28 ist außerdem ein Langloch 33 vorgesehen, in welches ein Zapfen 34 eines Lenkers 35 eingreift, der mit der Steuernußscheibe 17 schwenkbar verbunden ist.On the change lever 28, an elongated hole 33 is also provided, in which a pin 34 of a link 35 engages, which is pivotally connected to the control nut 17.

Wird wie in Figur 2 dargestellt, mittels eines Schlüssels 36 der Schließzylinder 22 in Richtung des Pfeils 37 betätigt, dann greift der Steuernocken 26 an der Steuerkante 27 des Wechselhebels 28 an und verlagert diesen nach oben, wodurch die zweite Steuerplatte 32 in Richtung des Pfeils 38 nach oben verschoben wird. An dieser zweiten Steuerplatte 32 ist eine zweite Treibstange 39 befestigt, die von der zweiten Steuerplatte 32 angetrieben wird. Über diese zweite Treibstange 39 wird ein Sperrschwenkbügelschloß angetrieben, insbesondere entriegelt. Diese Entriegelung erfolgt also dann, wenn mittels eines Schlüssels 36 der Schließzylinder 22 betätigt wird.If, as shown in FIG. 2, the locking cylinder 22 is actuated in the direction of the arrow 37 by means of a key 36, the control cam 26 engages the control edge 27 of the change lever 28 and displaces it upward, as a result of which the second control plate 32 in the direction of the arrow 38 up is moved. A second drive rod 39 is fastened to this second control plate 32 and is driven by the second control plate 32. A locking swivel lock is driven, in particular unlocked, via this second drive rod 39. This unlocking takes place when the lock cylinder 22 is actuated by means of a key 36.

Die oben beschriebene Verlagerung des Wechselhebels 28 über den Steuernocken 26 des Zahnrads 23 bewirkt außerdem eine Verschiebung des Lenkers 35, dessen Zapfen 34 am Endes des Langlochs 33 anliegt. Die Verschiebung des Lenkers 35, der gelenkig an der Steuernußscheibe 17 befestigt ist, bewirkt eine Verdrehung der Steuernußscheibe 17 in Richtung des Pfeils 13, wodurch, wie ebenfalls weiter oben beschrieben, die Falle 2 über das Ende 18, welches am Fallenschwanz 20 anliegt, zurückgezogen wird. Die Tür kann dann geöffnet werden.The above-described displacement of the change lever 28 over the control cam 26 of the gear 23 also causes a displacement of the link 35, the pin 34 of which rests against the end of the elongated hole 33. The displacement of the handlebar 35, which is articulated to the control nut disk 17, causes a rotation of the control nut disk 17 in the direction of arrow 13, whereby, as also described above, the latch 2 is withdrawn via the end 18, which bears against the latch tail 20 becomes. The door can then be opened.

In der Figur 3 wird die Drückernuß 5 durch Betätigen eines nicht dargestellten Drückers in Richtung des Pfeils 40 um die geometrische Achse 41 gedreht. Dies bewirkt eine Verdrehung der Steuernußscheibe 17 in die gleiche Richtung, d.h. in Richtung des Uhrzeigersinns, wodurch über das Ende 18, welches am Fallenschwanz 20 anliegt, die Falle 2 in Richtung des Pfeils 14 zurückgezogen wird. Außerdem wird der Lenker 35 verschoben, da dieser gelenkig mit der Steuernußscheibe 17 verbunden ist. Dabei verlagert sich der Zapfen 34 im Langloch 33. Eine Mitnahme des Wechselhebels 28 vom Lenker 35 erfolgt nicht, da der Zapfen 34 vom Wechselhebel 28 über das Langloch 33 abgekoppelt ist. Der Wechselhebel 28 verharrt somit in seiner in Figur 1 und Figur 3 gezeigten Ruhelage.In FIG. 3, the follower 5 is rotated about the geometric axis 41 in the direction of arrow 40 by actuating a lever, not shown. This causes the control nut disk 17 to rotate in the same direction, ie in the clockwise direction, as a result of which the latch 2 is withdrawn in the direction of the arrow 14 via the end 18 which bears against the latch tail 20. In addition, the handlebar 35 is displaced because it is articulated to the control nut 17. The pin 34 moves in the slot 33. The change lever 28 is not carried along by the handlebar 35, since the pin 34 is uncoupled from the change lever 28 via the elongated hole 33. The change lever 28 thus remains in its rest position shown in FIG. 1 and FIG. 3.

Wird also das Schloß 1 über einen Drücker betätigt, dann wird lediglich die Falle 2 in Richtung des Pfeils 14 zurückgezogen, jedoch nicht der Wechselhebel 28 bzw. über diesen die zweite Treibstange 39 betätigt. Ein Sperrschwenkbügelschloß, welches mit der zweiten Treibstange 39 in Verbindung steht, wird also nicht betätigt, so daß die Tür nicht vollständig geöffnet werden kann, sondern lediglich so weit, wie dies das Sperrschwenkbügelschloß zuläßt.Thus, if the lock 1 is actuated by a pusher, then the latch 2 is only retracted in the direction of the arrow 14, but the change lever 28 or the second drive rod 39 is not actuated by this. A locking swivel bracket lock, which is connected to the second drive rod 39, is therefore not actuated, so that the door cannot be opened completely, but only as far as the locking swivel bracket lock permits.
