Description

Die Erfindung betrifft eine Verriegelungseinrichtung für eine Tür oder ein Fenster mit einem Schließkasten und einem darin verschieblich angeordneten Fallenriegel, der eine Offenstellung, eine Schließstellung und eine Verriegelungsstellung einnehmen kann, wobei der Fallenriegel einen Fallenschaft aufweist und mit einem den Fallenriegel von der Schließstellung in die Verriegelungsstellung überführenden Sperrelement versehen ist, wobei die Verriegelungseinrichtung zudem eine Zusatzfalle aufweist, wobei im Schließkasten ein eine Verschiebung des Fallenriegels von der Schließstellung in die Verriegelungsstellung blockierendes Blockierelement vorgesehen ist, der Fallenriegel ein Arretierelement aufweist, an welchem das Blockierelement angreift und das Blockierelement mittels der Zusatzfalle aus dem Weg des Arretierelements herausgeführt wird.The invention relates to a locking device for a door or a window with a lock box and a latch bolt arranged displaceably therein, which can assume an open position, a closed position and a locking position, the latch bolt having a latch shaft and with a latch bolt from the closed position into the locking position transferring locking element is provided, wherein the locking device also has an additional latch, wherein a shifting of the latch bolt from the closed position into the locking position blocking element is provided in the lock box, the latch bolt has a locking element on which the blocking element engages and the blocking element off by means of the additional latch is led out the way of the locking element.

Eine solche Einrichtung ist z.B. aus US 5469723 bekannt, die dem Oberbegriff des Anspruchs 1 entspricht.Such a facility is, for example, off US 5469723 known, which corresponds to the preamble of claim 1.

Ein Einsteckschloss ist ebenfalls aus der EP 0 431 369 A2 bekannt. Dessen Fallenriegel ragt, wie bei herkömmlichen Fallen-Einsteckschlössern, in der Türoffenstellung lediglich mit seiner stirnseitigen Auflaufschräge aus der Schlossstulpe heraus, bietet aber letzteren gegenüber den Vorteil, dass der Fallenriegel in der Türschließstellung selbsttätig tiefer in das türrahmenseitig gelegene Schließblech einfährt, wodurch bereits durch diesen tiefen Schließeingriff eine größere Aufbruchsicherheit der Tür erzielt wird. Außerdem kann der Fallenriegel in seiner voll ausgefahrenen Verriegelungsposition, in der seine Auflaufschräge im Schließblech vollständig verschwindet, nicht durch unbefugtes Einbringen eines ausreichend festen Gegenstandes, wie z.B. eines flexiblen Blechs, Schraubenzieher oder einer Scheckkarte, in den zwischen Türschloss und Schließblech gelegenen Türspalt zurückbewegt werden, wie das bei einfachen Fallenschlössern leicht möglich ist.A mortise lock is also from the EP 0 431 369 A2 known. As with conventional latch mortise locks, its latch bolt only protrudes from the lock cuff with its frontal bevel in the door open position, but has the advantage over the latter that the latch bolt automatically moves deeper into the strike plate on the door frame side in the door closed position, which is already through this deep locking engagement, the door is more secure against being broken. In addition, the latch bolt in its fully extended locking position, in which its approach slope disappears completely in the strike plate, cannot be moved back into the door gap between the door lock and strike plate by unauthorized introduction of a sufficiently rigid object, such as a flexible sheet metal, screwdriver or a credit card. as is easily possible with simple latch locks.

Beim bekannten Fallenriegel-Einsteckschloss ist das den Fallenriegel in seiner teilweise ausgefahrenen Zwischenstellung arretierende Sperrelement als in einer nutförmigen Aussparung des Fallenriegels lose gelagerte, unter Federwirkung stehende Sperrklinke ausgebildet, während der Auslöser über die Fallenschräge vorsteht, so dass er beim Schließen der Tür betätigt wird und dadurch den Fallenriegel für seine volle Ausfahrbewegung freigibt. Die stirnseitig zugängliche Lage des Auslösers am Fallenriegel weist aber den Nachteil auf, dass er bei offener Tür leicht manuell zu betätigen und damit zu verstellen ist, wodurch der Fallenriegel ungewollt bereits vorzeitig in seine volle Ausfahrstellung herausfahren kann. Das kann beim unachtsamen Zuschlagen der Tür zu erheblichen Beschädigungen führen. Darüber hinaus könnte die vorbeschriebene Fehlfunktionsmöglichkeit dazu führen, dass ein solches Schloss in Brandschutztüren nicht verwendet werden darf.In the known latch bolt mortise lock, the locking element locking the latch bolt in its partially extended intermediate position is designed as a pawl loosely mounted under spring action in a groove-shaped recess of the latch bolt, while the trigger protrudes over the latch bevel so that it is actuated when the door is closed and this releases the latch bolt for its full extension movement. The front side accessible position of the trigger on the latch bolt has the disadvantage that it can easily be operated manually with the door open and thus adjusted, whereby the latch bolt can unintentionally move out prematurely into its fully extended position. If the door is carelessly slammed, this can lead to considerable damage. In addition, the possibility of malfunction described above could mean that such a lock may not be used in fire protection doors.

Die DE 44 07 244 C1 und die DE 197 01 761 C1 zeigen Schlösser mit einer Hilfsfalle, über welche eine Schieberplatte angesteuert wird, die den Riegel und/oder die Falle separat verriegelt. Eine Manipulation des Fallenriegels ist somit nicht ohne weiteres möglich.The DE 44 07 244 C1 and the DE 197 01 761 C1 show locks with an auxiliary latch via which a slide plate is actuated that locks the bolt and / or the latch separately. A manipulation of the latch bolt is therefore not easily possible.

Der Erfindung liegt die Aufgabe zugrund eine Verriegelungseinrichtung bereit zu stellen, welche eine noch höhere Sicherheit gegen Manipulation aufweist.The object of the invention is to provide a locking device which is even more secure against manipulation.

Diese Aufgabe wird bei der eingangs genannten Verriegelungseinrichtung erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.This object is achieved according to the invention in the locking device mentioned at the outset by the characterizing features of claim 1.

Bei der erfindungsgemäßen Verriegelungseinrichtung wird die Verschiebung des Fallenriegels blockiert oder verhindert, wenn diese nicht ordnungsgemäß betätigt wird. Zwar kann der im Fallenriegel untergebrachte Auslöser nach wie vor bei offener Tür betätigt werden, jedoch führt dies nicht dazu, dass der Fallenriegel aus seiner Schließstellung in die Verriegelungsstellung verlagert wird. Der Fallenriegel wird zwar in seiner Schließstellung entriegelt, kann jedoch nicht weiter ausfahren, da seine Verschiebung in Auswärtsrichtung blockiert wird. Die Tür kann aber problemlos geschlossen werden, da der Fallenriegel weiterhin eingeschoben werden kann, weil er lediglich mit seinem, die Fallenschräge aufweisenden Abschnitt über die Stulpe übersteht.In the locking device according to the invention, the displacement of the latch bolt is blocked or prevented if it is not properly actuated. Although the trigger accommodated in the latch bolt can still be actuated with the door open, this does not mean that the latch bolt is shifted from its closed position into the locking position. The latch bolt is unlocked in its closed position, but cannot extend any further because it is blocked from moving in the outward direction. However, the door can be closed without any problems, since the latch bolt can still be pushed in because it only protrudes over the cuff with its section having the latch bevel.

Bei einer Weiterbildung der Erfindung ist vorgesehen, dass das Arretierelement in Verschieberichtung des Fallenriegels verlagerbar ist. Dieses Arretierelement besitzt die Aufgabe, eine Verschiebung des Fallenriegels zu verhindern, wenn die Tür nicht vorschriftsmäßig geschlossen worden ist. Da sich das Arretierelement im Schließkasten befindet, ist es vor einer Manipulation geschützt.In a further development of the invention it is provided that the locking element can be displaced in the displacement direction of the latch bolt. This locking element has the task of preventing the latch bolt from shifting if the door has not been properly closed. Since the locking element is located in the lock box, it is protected from manipulation.

Die Erfindung sieht vor, dass das Arretierelement von einem quer zur Verschieberichtung des Fallenriegels quer zur Verschieberichtung des Blockierelements vorspringenden Zapfen gebildet wird. Dieser Zapfen ist entweder einstückig am Fallenriegel angeformt oder mit diesem verbolzt. Vorzugsweise befindet sich der Zapfen am Fallenschaft, so dass dessen Position innerhalb des Schließkastens stets gleich und unabhängig von der Kastenbreite und vom Dornmaß ist.The invention provides that the locking element is formed by a pin protruding transversely to the direction of displacement of the latch bolt and transversely to the direction of displacement of the blocking element. This pin is either integrally formed on the latch bolt or bolted to it. The pin is preferably located on the latch shaft so that its position within the lock box is always the same and independent of the box width and the backset.

Das Blockierelement ist quer zur Verschieberichtung des Fallenriegels und insbesondere in der Ebene des Schließkastens oder Einsteckschlosses verschieblich im Schließkasten gelagert. Hierdurch ist es auf einfache Weise einfach möglich, dass das Blockierelement eine Stellung einnehmen kann, in welcher es kollisionsfrei zum Fallenriegel liegt oder in dessen Verschiebeweg eingreift und diesen blockieren kann.The blocking element is slidably mounted in the lock box transversely to the direction of displacement of the latch bolt and in particular in the plane of the lock box or mortise lock. This makes it possible in a simple manner for the blocking element to be able to assume a position in which it lies without collision with the latch bolt or engages in its displacement path and can block it.

Um zu ermöglich, dass der Fallenriegel lediglich in Ausschubrichtung blockiert wird, weist das Blockierelement eine entgegen der Ausschieberichtung des Fallenriegels randoffene Ausnehmung auf. In dieser Ausnehmung wird vorteilhaft der Zapfen gefangen, so dass in der Blockierstellung des Blockierelements das Arretierelement in der Ausnehmung liegt. Der Fallenriegel kann weiterhin in den Schließkasten eingeschoben werden, da der Zapfen die Ausnehmung in Einschubrichtung des Fallenriegels verlassen, d.h. heraustreten kann.In order to enable the latch bolt to be blocked only in the push-out direction, the blocking element has a recess which is open at the edge against the pushing-out direction of the latch bolt. In this recess the pin is advantageously caught, so that in the blocking position of the blocking element, the locking element lies in the recess. The latch bolt can still be pushed into the lock box, since the pin can leave the recess in the direction of insertion of the latch bolt, ie it can step out.

Um die Bewegung der Zusatzfalle, insbesondere deren Einschubbewegung, einfach auf das Blockierelement übertragen zu können, ist die Zusatzfalle mit einem Antrieb für das Blockierelement gekoppelt. Dabei kann die Bewegungsrichtung und/oder die Streckenlänge des Einschubs der Zusatzfalle an die Erfordernisse des Blockierelements angepasst werden. Es besteht auch die Möglichkeit, dass die Verschiebebewegung der Zusatzfalle über den Antrieb vom Blockierelement abgekoppelt wird. Dies ist z.B. für den Fall erforderlich, dass die Zusatzfalle unzulässigerweise oder unbeabsichtigt manuell bei nicht geschlossener Tür betätigt wird.In order to be able to easily transfer the movement of the additional latch, in particular its insertion movement, to the blocking element, the additional latch is coupled to a drive for the blocking element. The direction of movement and / or the length of the path of the insertion of the additional latch can be adapted to the requirements of the blocking element. There is also the possibility that the displacement movement of the additional latch is decoupled from the blocking element via the drive. This is e.g. required in the event that the additional latch is inadmissibly or unintentionally actuated manually when the door is not closed.

Eine bevorzugte Ausführungsform der Erfindung sieht vor, dass der Antrieb ein Antriebsgehäuse und einen im Antriebsgehäuse verschieblich gelagerten Stempel aufweist. Dabei greift die Zusatzfalle an einer Stirnfläche des Stempels an, wobei der Stempel sich mit seiner gegenüberliegenden Stirnfläche gegen die Kraft einer ersten Feder am Antriebsgehäuse abstützt. Die Stellung der Zusatzfalle wird also direkt an den Stempel übertragen, wohingegen die Stellung des Stempels kraftabhängig auf das Antriebsgehäuse übertragen wird. Ist die Gegenkraft größer als die Kraft der ersten Feder, dann verbleibt das Antriebsgehäuse in seiner augenblicklichen Position und die erste Feder wird komprimiert. Bevorzugt ist das Antriebsgehäuse verschieblich im Schließkasten gelagert.A preferred embodiment of the invention provides that the drive has a drive housing and a plunger mounted displaceably in the drive housing. The additional latch acts on an end face of the ram, the ram being supported with its opposite face against the force of a first spring on the drive housing. The position of the additional latch is thus transmitted directly to the punch, whereas the position of the punch is transmitted to the drive housing as a function of the force. If the counterforce is greater than the force of the first spring, the drive housing remains in its current position and the first spring is compressed. The drive housing is preferably mounted displaceably in the lock box.

Bei einem bevorzugten Ausführungsbeispiel ist vorgesehen, dass das Antriebsgehäuse einen Schwenkhebel antreibt, der mit einem ersten Schwenkarm am Blockierelement angreift. Der Schwenkarm besitzt den Vorteil, dass über ihn die erforderlichen Hebelkräfte zum Verschieben oder Verschwenken des Blockierelements bedarfsgerecht eingestellt werden können. Außerdem ist die Lagerung des Schwenkarms relativ einfach, da es lediglich eines Lagerzapfens bedarf.In a preferred exemplary embodiment it is provided that the drive housing drives a pivot lever which engages the blocking element with a first pivot arm. The swivel arm has the advantage that it can be used to set the lever forces required to move or swivel the blocking element as required. In addition, the mounting of the swivel arm is relatively simple, since only one bearing pin is required.

Eine Weiterbildung der Erfindung sieht vor, dass der Schwenkhebel über eine zweite Feder in eine der Blockierlage für das Blockierelement entsprechende Ruhelage gedrängt wird. Diese zweite Feder erzeugt die Gegenkraft für die erste Feder und dient zur Rückstellung des Schwenkhebels und des Blockierelements in die Ausgangs- oder Blockierlage.A further development of the invention provides that the pivot lever is urged by a second spring into a rest position corresponding to the blocking position for the blocking element. This second spring generates the counterforce for the first spring and serves to return the pivot lever and the blocking element to the initial or blocking position.

Um zu verhindern, dass sich die zweite Feder als störend für den Verrieglungsablauf auswirkt ist vorgesehen, dass die Federkraft der ersten Feder auf den Stempel größer ist, als die Federkraft der zweiten Feder auf den Schwenkhebel. Die Federkraft der zweiten Feder wird also vom Antrieb überwunden, so dass der Schwenkhebel und das Blockierelement betätigt werden. Wird jedoch das Blockierelement festgehalten, wenn der Fallenriegel seine Schließstellung einnimmt und nicht in seine Offenstellung überführt worden ist, dann wird die erste Feder komprimiert, sobald der Stempel verlagert wird.To prevent the second spring from interfering with the locking process, it is provided that the spring force of the first spring on the plunger is greater than the spring force of the second spring on the pivot lever. The spring force of the second spring is thus overcome by the drive so that the pivot lever and the blocking element are actuated. However, if the blocking element is retained when the latch bolt is in its closed position and has not been moved into its open position, then the first spring is compressed as soon as the plunger is displaced.

Um die Schwenkbewegung des Schwenkhebels in eine lineare Bewegung für das Blockierelement umzusetzen, läuft das freie Ende des ersten Schwenkarmes in einer Kulisse des Blockierelements. Die Kulisse wird vorteilhaft von einer Zapfen-Nut-Verbindung realisiert.In order to convert the pivoting movement of the pivot lever into a linear movement for the blocking element, the free end of the first pivot arm runs in a link of the blocking element. The backdrop is advantageously realized by a pin-and-groove connection.

Eine bevorzugte Verbindung von Antriebsgehäuse und Schwenkhebel wird dadurch erzielt, dass der Schwenkhebel einen zweiten Schwenkarm aufweist und das freie Ende des zweiten Schwenkarmes in eine Ausnehmung am Antriebsgehäuse eingreift. Die Ausnehmung am Antriebsgehäuse arbeitet nach Art einer Zahnstange, wohingegen das freie Ende des zweiten Schwenkarmes als in die Zahnstange eingreifender Zahn fungiert.A preferred connection of the drive housing and pivot lever is achieved in that the pivot lever has a second pivot arm and the free end of the second pivot arm engages in a recess on the drive housing. The recess on the drive housing works like a rack, whereas the free end of the second swivel arm acts as a tooth that engages in the rack.

Um die Zusatzfalle, insbesondere deren Ausschub oder Überstand, an unterschiedliche Spaltbreiten zwischen Tür und Festrahmen anzupassen, ist die Lage der Zusatzfalle bezüglich des Stempels einstellbar positionierbar. Dies erfolgt dadurch, dass die Zusatzfalle mehr oder weniger weit in den Stempel einschiebbar und die der gewünschten Position arretierbar ist.In order to adapt the additional latch, in particular its extension or protrusion, to different gap widths between the door and the fixed frame, the position of the additional latch with respect to the ram can be positioned in an adjustable manner. This takes place in that the additional latch can be pushed more or less far into the punch and the one in the desired position can be locked.

Die Figur 1 zeigt einen Ausschnitt einer insgesamt mit 10 bezeichneten Verriegelungsvorrichtung mit einem Schließkasten 12, in welchem ein Fallenriegel 14 verschieblich geführt ist. Außerdem ist eine mit Kunststoff ummantelte und dadurch geräuschgedämmte Zusatzfalle 16 erkennbar, die bei diesem Ausführungsbeispiel ebenfalls im Schließkasten 12 angeordnet ist. Sie könnte aber auch in einem Zusatzkasten untergebracht sein, wobei der Zusatzkasten über geeignete Verbindungsmittel mit dem Schließkasten 12 mechanisch gekoppelt ist.The Figure 1 shows a section of a locking device denoted overall by 10 with a lock box 12 in which a latch bolt 14 is displaceably guided. In addition, an additional latch 16 encased in plastic and thereby noise-insulated can be seen, which in this embodiment is also arranged in the lock box 12. she but could also be accommodated in an additional box, the additional box being mechanically coupled to the lock box 12 via suitable connecting means.

Der Fallenriegel 14 nimmt in der Figur 1 seine Verriegelungsstellung ein und ist vollständig aus dem Schließkasten 12 ausgefahren, was über eine Fallenfeder 18 erfolgt, die sich am Schließkasten 12 abstützt und rückwärtig an einem Fallenschaft 20 des Fallenriegels 14 angreift. In der Figur 1 sind noch ein Blockierelement 22, welches in vertikaler Richtung verschieblich im Schließkasten 12 gelagert ist, und ein Schwenkhebel 24 erkennbar, welcher um einen Zapfen 26 schwenkbar gelagert ist und einen ersten Schwenkarm 28 und einen zweiten Schwenkarm 30 aufweist. Schließlich ist noch erkennbar, dass die Zusatzfalle 16 mit einem Antrieb 32 verbunden ist, was später noch im Detail beschrieben wird.The latch bolt 14 takes in the Figure 1 its locking position and is completely extended out of the lock box 12, which takes place via a latch spring 18 which is supported on the lock box 12 and engages a latch shaft 20 of the latch bolt 14 at the rear. In the Figure 1 A blocking element 22, which is mounted in the lock box 12 so as to be displaceable in the vertical direction, and a pivot lever 24 can also be seen, which is pivotably mounted about a pin 26 and has a first pivot arm 28 and a second pivot arm 30. Finally, it can also be seen that the additional latch 16 is connected to a drive 32, which will be described in detail later.

Die Figur 2 zeigt den Schließkasten 12 mit in Schließlage sich befindendem Fallenriegel 14, der lediglich mit seiner Fallenschräge eine Stulpe 34 überragt. Am Fallenschaft 20 befindet sich ein Arretierelement 36 in Form eines quer (orthogonal) zur Verschieberichtung abragenden Zapfens 40, der in eine randoffene Ausnehmung 42 am Ende des Blockierelements 22 eingreift. Die Ausnehmung 42 ist dabei entgegen der Verschieberichtung 38 offen und hält den Zapfen 40 formschlüssig fest. Das Blockierelement 22 erstreckt sich ebenfalls quer zur Verschieberichtung 38 und quer zum Arretierelement 36 und ist in Erstreckungsrichtung, also vertikal verschieblich gelagert. Am der Ausnehmung 42 gegenüberliegenden Ende weist das Blockierelement 22 ein gebogenes oder gekrümmtes Langloch 44 auf, welches Teil einer Kulisse 46 ist, zu welcher noch ein in das Langloch 44 eingreifender Zapfen 48 gehört, der vom Ende des ersten Schwenkarms 28 abragt. Das Ende des zweiten Schwenkarms 30 greift in eine Ausnehmung 50 des Antriebs 32.The Figure 2 shows the lock box 12 with the latch bolt 14 in the closed position, which only protrudes over a cuff 34 with its latch slope. On the latch shaft 20 there is a locking element 36 in the form of a pin 40 which protrudes transversely (orthogonally) to the direction of displacement and which engages in an open-edged recess 42 at the end of the blocking element 22. The recess 42 is open against the direction of displacement 38 and holds the pin 40 in a form-fitting manner. The blocking element 22 also extends transversely to the displacement direction 38 and transversely to the locking element 36 and is mounted so as to be vertically displaceable in the direction of extent. At the end opposite the recess 42, the blocking element 22 has a bent or curved elongated hole 44 which is part of a link 46 to which a pin 48 which engages in the elongated hole 44 and projects from the end of the first pivot arm 28 also belongs. The end of the second pivot arm 30 engages in a recess 50 of the drive 32.

Der Antrieb 32 weist einen Stempel 52 und ein den Stempel 52 aufnehmendes Antriebsgehäuse 54 auf, an welchem die Ausnehmung 50 vorgesehen ist. Im Stempel 52 ist die Zusatzfalle 16 gelagert und der Stempel 52 stützt sich mittels einer ersten Feder 56, einer Wendelfeder, am Grund des Antriebsgehäuses 54 ab. Außerdem ist eine zweite Feder 58, eine Schenkelfeder, erkennbar, die um den Zapfen 26 geschlungen ist und den Zapfen 48 entgegen der Richtung des Uhrzeigersinns drängt. Die Federkraft der zweiten Feder 58 ist kleiner als die Federkraft der ersten Feder 56.The drive 32 has a punch 52 and a drive housing 54 which receives the punch 52 and on which the recess 50 is provided. The additional latch 16 is mounted in the punch 52 and the punch 52 is supported on the base of the drive housing 54 by means of a first spring 56, a helical spring. In addition, a second spring 58, a leg spring, can be seen which is looped around the pin 26 and urges the pin 48 counter-clockwise. The spring force of the second spring 58 is smaller than the spring force of the first spring 56.

Wird beim Schließen einer (nicht dargestellten) Tür die Zusatzfalle 16, wie in der Figur 2 dargestellt, eingeschoben, dann wird auch der Stempel 52 verlagert. Da die Federkraft der ersten Feder 56 größer ist als die Federkraft der zweiten Feder 58, verlagert der Stempel 52 das Antriebsgehäuse 54 in Verschieberichtung der Zusatzfalle 16, wodurch der Schwenkhebel 24 über den zweiten Schwenkarm 30 im Uhrzeigersinn verschwenkt wird und dabei die zweite Feder 58 spannt. Der Zapfen 48 fährt an das andere Ende des Langlochs 44 , wodurch der das Blockierelement 22 nach unten verschoben wird. Dies erfolgt beim Schließen der Tür, bei der auch der Fallenriegel 14 in den Schließkasten 12 eingeschoben wird, wodurch der Zapfen 40 nach links, d.h. aus der Ausnehmung 42 des Blockierelements 22 ausgeschoben wird. Schnappt bei geschlossener Tür der Fallenriegel 14 in die Fallenaufnahme des Schließblechs am Festrahmen, dann fährt der Fallenriegel 14 von seiner Offenstellung über die Schließstellung gemäß Figur 3 in die Verrieglungsstellung gemäß Figur 1. Die Zusatzfalle 16 kann eingedrückt bleiben.When closing a door (not shown), the additional latch 16, as in Figure 2 shown, inserted, then the punch 52 is also displaced. Since the spring force of the first spring 56 is greater than the spring force of the second spring 58, the plunger 52 shifts the drive housing 54 in the direction of displacement of the additional latch 16, whereby the pivot lever 24 is pivoted clockwise via the second pivot arm 30, thereby tensioning the second spring 58 . The pin 48 moves to the other end of the elongated hole 44, whereby the blocking element 22 is moved downwards. This takes place when the door is closed, during which the latch bolt 14 is also pushed into the lock box 12, as a result of which the pin 40 is pushed out to the left, ie out of the recess 42 of the blocking element 22. When the latch bolt 14 snaps into the latch receptacle of the strike plate on the fixed frame when the door is closed, the latch bolt 14 moves from its open position to the closed position according to FIG Figure 3 into the locking position according to Figure 1 . The additional latch 16 can remain depressed.

Vorteilhaft fährt die Zusatzfalle 16 aber ebenfalls wieder aus dem Schließkasten 12 aus, so dass das Blockierelement 22 wieder seine Ausgangslage einnimmt, in welche es von der Kulisse 46, unterstützt von der zweiten Feder 48, gedrängt wird. Der Zapfen 40 befindet sich dann zwischen der Stulpe 34 und dem Blockierelement 22, welches an seinem Ende eine Nase 60 aufweist, die die Lage des Zapfens 40 sichert. Der Fallenriegel 14 kann mittels eines Werkzeugs nicht in den Schließkasten 12 eingedrückt werden.Advantageously, however, the additional latch 16 also moves out of the lock box 12 again, so that the blocking element 22 resumes its starting position, into which it is urged by the link 46, supported by the second spring 48. The pin 40 is then located between the cuff 34 and the blocking element 22, which has a nose 60 at its end, which secures the position of the pin 40. The latch bolt 14 cannot be pressed into the lock box 12 by means of a tool.

Die Figur 4 zeigt die gleiche Situation und Stellung der Bauteile, wie die Figur 2. Wird die Zusatzfalle 16, wie in Figur 4 dargestellt, zu Manipulationszwecken, z.B. manuell in den Schließkasten 12 eingedrückt, dann wird der Stempel 52 verschoben. Das Antriebsgehäuse 54 wird aber durch das über den Zapfen 40 gefangene Blockierelement 22 und den Schwenkhebel 24 blockiert, so das die erste Feder 56 komprimiert wird. Sobald die Zusatzfalle 16 losgelassen wird, wird sie über die erste Feder 56 wieder aus dem Schließkasten 12 ausgeschoben.The Figure 4 shows the same situation and position of the components as the Figure 2 . If the additional trap 16, as in Figure 4 shown, for manipulation purposes, for example manually pressed into the lock box 12, then the punch 52 is moved. The drive housing 54 is, however, blocked by the blocking element 22 caught by the pin 40 and the pivot lever 24, so that the first spring 56 is compressed. As soon as the additional latch 16 is released, it is pushed out of the lock box 12 again via the first spring 56.

Andererseits bewirkt eine Manipulation des Fallenriegels 14 keinen Ausschub desselben aus dem Schließkasten 12 und somit aus der Stulpe 34, da der Fallenriegel 14 vom Blockierelement 22, welches mit seiner Ausnehmung 42 den Zapfen 40 hintergreift, daran gehindert wird, von der Fallenfeder 18 ausgeschoben zu werden.On the other hand, manipulation of the latch bolt 14 does not cause it to be pushed out of the lock box 12 and thus out of the cuff 34, since the latch bolt 14 is prevented by the blocking element 22, which engages behind the pin 40 with its recess 42, from being pushed out by the latch spring 18 .

Die Figur 6 zeigt schließlich noch eine Einrichtung, mit welcher der Überstand der Zusatzfalle 16 über die Stulpe 34 eingestellt werden kann. Die Zusatzfalle 16 besitzt einen Fallenschaft 62, der im Stempel 52 gelagert ist. Am Fallenschaft 62 befinden sich nebeneinander nach Art einer Zahnstange mehrere Einkerbungen 64, in welche die Spitze einer Madenschraube 66 eingreift, welche in den Stempel 52 eingeschraubt ist. Soll der Überstand der Zusatzfalle 16 verstellt werden, dann wird die Madenschraube 66 gelöst, die Lage des Fallenschaftes 62 im Stempel 52 verändert und die Madenschraube 66 so fixiert, dass sie in eine andere Einkerbung 64 eingreift.The Figure 6 finally shows a device with which the protrusion of the additional latch 16 over the cuff 34 can be adjusted. The additional latch 16 has a latch shaft 62 which is mounted in the punch 52. On the latch shaft 62 there are several notches 64 next to one another in the manner of a toothed rack, in which the tip of a grub screw 66 engages, which is screwed into the punch 52. If the protrusion of the additional latch 16 is to be adjusted, the grub screw 66 is loosened, the position of the latch shaft 62 in the punch 52 is changed and the grub screw 66 is fixed in such a way that it engages in another notch 64.
