Description

Die Erfindung betrifft eine Verriegelungseinrichtung für eine Tür, ein Fenster o.dgl., mit einem Hauptschließkasten, wenigstens einem Zusatzschließkasten und wenigstens einer den Zusatzschließkasten mit dem Hauptschließkasten verbindenden Treibstange, wobei der Zusatzschließkasten einen frei zurückschiebbaren Fallenriegel aufweist, durch eine Feder und/oder durch ein Getriebe über die normale Fallenstellung hinaus in seine Verriegelungsstellung schiebbar ist, und an seiner einer Auflaufschräge gegenüberliegenden Seite und im Bereich des Fallenschwanzes einen Vorsprung auf, an dem ein Fallenrückstellhebel angreift und der Fallenrückstellhebel einen ersten Mitnehmer aufweist, über welchen eine Treibstange in die eine Richtung mitgenommen wird.The invention relates to a locking device for a door, a window or the like, with a main lock box, at least one additional lock box and at least one the additional lock box with the main lock box connecting drive rod, the additional lock box has a freely retractable latch bolt, by a spring and / or through a gearbox over the normal Fall position out into its locking position is slidable, and at its one ramp opposite side and in the area of the trap tail a tab on which a latch reset lever attacks and the latch reset lever a first Has driver, via which a connecting rod in the a direction is taken.

Aus der DE 35 05 379 C1 ist ein Treibstangenschloß bekannt geworden, welches über eine Treibstange mit einem Mittelschloß verbunden ist. Diese Treibstange verbindet also die beiden Fallen der beiden Schlösser. Auf diese Weise kann eine Tür nicht nur in der Mitte, sondern auch im Bereich ihrer Ecken mit dem türrahmenseitigen Schließblech verbunden werden. Beim Schließen der Tür werden über das Schließblech die Fallen eingeschoben, so daß die Tür ihre Schließstellung einnehmen kann. Zum Öffnen der Tür wird die Falle des Mittelschlosses über einen Drücker oder einen Schließzylinder betätigt und zurückgezogen, wobei diese Bewegung über die Treibstange auf die Falle des Treibstangenschlosses übertragen wird, so daß auch diese Falle zurückgeschoben wird. Dabei ist nachteilig, daß bei der Einschubbewegung der Falle stets auch die Treibstange bewegt wird. Dies führt zu einer Schwergängigkeit der Falle und zu Funktionsstörungen.A drive rod lock is known from DE 35 05 379 C1 which has a connecting rod with a Middle lock is connected. This connecting rod connects so the two latches of the two locks. To this Way a door can not only in the middle, but also in the Area of their corners with the striking plate on the door frame side get connected. When you close the door, you will be over the Strike plate inserted the latches, so that the door their Can assume the closed position. To open the door, the Case of the middle lock via a handle or a Lock cylinder actuated and withdrawn, this Movement over the drive rod on the trap of the Espagnolette lock is transmitted so that this too Trap is pushed back. It is disadvantageous that at the slide-in movement of the trap always also the drive rod is moved. This leads to a stiff trap and malfunctions.

Mit der EP 431 369 A2 ist ein Einsteckschloß mit einem Fallenriegel bekannt geworden. Dieser Fallenriegel hat neben der Aufgabe eines herkömmlichen Riegels die Aufgabe, die Tür zusätzlich zu verriegeln, was dadurch bewirkt wird, daß der Fallenriegel nach dem Schließen der Tür von einer Fallenstellung selbsttätig in eine Verriegelungsstellung übergeht, in der er weiter aus dem Einsteckschloß ausgeschoben wird als in der Fallenstellung und dadurch weit in das türrahmenseitige Schließblech eingreift. Ein solcher Fallenriegel kann in der Regel nicht mehr durch Einschieben eines Werkzeugs in den Schlitz zwischen der Tür und dem Türrahmen zurückgeschoben werden. Eine Tür mit einem solchen Fallenriegel ist nach dem Schließen automatisch verriegelt.EP 431 369 A2 is a mortise lock with one Latchbolt became known. This latchbolt has in addition to the task of a conventional bar, the task to additionally lock the door, which is caused by that the latch has been closed by a Latch position automatically in a locking position passes, in which he continues from the mortise lock is pushed out as in the trap position and thereby engages far into the striking plate on the door frame side. A such latchbolts can usually no longer Insert a tool into the slot between the door and pushed back the door frame. A door with Such a latchbolt is after closing locked automatically.

Mir der DE 296 05 517 U1 ist eine Verriegelungseinrichtung der eingangs genannten Art bekannt geworden, bei der jedoch die Gefahr besteht, dass der federbeaufschlagte Fallenriegel des Zusatzschließkastens bei verzogenen Türen möglicherweise nicht vollständig in das Schließblech des Türblendrahmens eitritt, sondern am Schließblech klemmt.DE 296 05 517 U1 is a locking device of the type mentioned at the outset, however there is a risk that the spring-loaded Latch bolt of the additional lock box with warped doors may not be fully in the striking plate of the Door frame is free, but stuck to the striking plate.

Der Erfindung liegt die Aufgabe zugrunde, eine Verriegelungseinrichtung mit Zusatzschließkästen bereitzustellen, mit der die Tür einen besseren Widerstand gegen Einbruch bietet und darüber hinaus die Verriegelungsfunktion zuverlässig eintritt.The invention has for its object a Locking device with additional lock boxes provide the door with better resistance offers against burglary and also the Locking function reliably occurs.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß bei der Verriegelungseinrichtung der eingangs genannten Art der Fallenrückstellhebel einen zweiten Mitnehmer aufweist, über den er von der Treibstange in die andere Richtung mitgenommen wird.This object is achieved in that the locking device of the type mentioned The latch return lever has a second driver which he pushes in the other direction is taken away.

Mit der erfindungsgemäßen Verriegelungseinrichtung wird der Vorteil erzielt, daß die Tür außerhalb der Mitte, d.h. wenigstens im Bereich einer Ecke über den Fallenriegel gehalten und auch verriegelt werden kann. Fällt eine mit der erfindungsgemäßen Verriegelungseinrichtung ausgestattete Tür ins Schloß, dann wird zunächst der Fallenriegel über das türrahmenseitige Schließblech zurückgeschoben, wodurch ein Schließen der Tür ermöglicht wird. Befindet sich die Tür in der Schließlage, wird der Fallenriegel aus dem Zusatzschließkasten ausgeschoben und geht über seine Fallenstellung hinaus in eine Verriegelungsstellung. In dieser Lage kann der Fallenriegel z.B. durch Einschieben eines flachen Werkzeugs in den Spalt zwischen der Tür und dem Türrahmen nicht zurückgeschoben werden. Eine derart verriegelte Tür bietet einen hohen Widerstand gegen Einbruch. Durch den zweiten Mitnehmer wird gewährleistet, dass mit einer Abwärtsbewegung der Treibstange, was durch ein Abschließen des Hauptschlosses mittels Schlüssels bewirkt wird, der Fallenriegel zwangsweise ausgefahren wird. Sollte der Fallenriegel am Schließblech des Türblendrahmens klemmen, wird dies entweder beim Betätigen des Schlüssels bemerkt, so dass die Tür korrekt verschlossen werden kann, oder durch die Schließbewegung des Schlüssels wird die Klemmwirkung überwunden und der Fallenriegel vorgeschlossen.With the locking device according to the invention Achieved advantage that the door is off center, i.e. at least in the area of a corner above the latchbolt can be held and locked. If one falls with the locking device according to the invention equipped door to the castle, then the first Latch latches on the striking plate on the door frame side pushed back, allowing the door to be closed becomes. If the door is in the closed position, the The latch bolt is pushed out of the additional lock case and goes beyond its trap position in one Locking position. In this position the latchbolt can e.g. by inserting a flat tool into the gap not pushed back between the door and the door frame become. Such a locked door offers a high one Burglary resistance. By the second driver ensures that with a downward movement of the Connecting rod, what by locking the main lock by means of a key, the latch bolt is forced to extend. If the latch bolt on Clamp the striking plate of the door frame, this will either noticed when pressing the key so that the Door can be closed correctly, or through the Closing movement of the key becomes the clamping effect overcome and the latch bolt closed.

Bei einem Ausführungsbeispiel ist vorgesehen, dass der zweite Mitnehmer von einer Abkantung oder Abkröpfung des Fallenrückstellhebels gebildet wird. Ein derartiges Bauteil ist einfach und preiswert herstellbar. Außerdem sind existierende Fallenrückstellhebel problemlos gegen den erfindungsgemäßen Fallenrückstellhebel auswechselbar.In one embodiment, it is provided that the second driver of a bend or an offset of the Trap reset lever is formed. Such a component is easy and inexpensive to manufacture. Also are existing latch reset lever easily against the latch reset lever according to the invention exchangeable.

Ein anderes Ausführungsbeispiel sieht vor, dass der zweite Mitnehmer von einem Anschweißteil gebildet wird. Auf diese Weise sind die erfindungsgemäßen Fallenrückstellhebel ebenfalls preiswert und einfach herstellbar.Another embodiment provides that the second Driver is formed by a weld-on part. To this The latch reset levers according to the invention are suitable also inexpensive and easy to manufacture.

Der Ausschubhub des Fallenriegels wird bei einer Variante erfindungsgemäß dadurch bewirkt, dass der Hauptschlossriegel einen beim Vorschließen auf die Treibstange einwirkenden Fortsatz aufweist. Durch diesen Fortsatz wird die Treibstange verschoben, so dass über den Fallenrückstellhebel der Fallenriegel auch gegen eventuelle geringfügige Widerstände ausgeschoben wird.The extension stroke of the latch bolt is in one variant according to the invention in that the Master lock bolt one when closing on the Has drive rod acting extension. Through this The extension rod is shifted so that over the Latch reset lever of the latch bolt also against possible slight resistance is pushed out.

Die Steuernußscheibe 16 weist einen weiteren Arm 20 auf, der an einem Fallenfuß 21 der Falle 8 anliegt.In the view of the Main lock box 2, the box cover 5 is removed, see above that the closing mechanism is recognizable. For example, of the from the lock cylinder 7 actuated change 12, the a bolt 13 on a slide 14 of an arm 15 a Control nut 16 attacks, recognizable. The slide 14 acts on a sliding stop 17 on one Control plate 18 is attached. In this control plate 18 is the drive rod 11 hooked in at 19. The steering nut washer 16 has a further arm 20, which is on a trap foot 21 the case 8 is present.

Wird über den Schließzylinder 7 der Wechsel 12 und über diesen die Steuernußscheibe 16 in Richtung des Uhrzeigersinns betätigt, dann wird über den Arm 20 und den Fallenfuß 21 die Falle 8 in den Hauptschließkasten 2 eingezogen. Dies kann jedoch auch dadurch erfolgen, daß die Drückernuß 6 mittels eines nicht dargestellten Drückers in Richtung des Uhrzeigersinns betätigt wird, wobei die Drückernuß 6 die Steuernußscheibe 16 bei ihrer Drehbewegung mitnimmt. Außerdem wird beim Betätigen des Schließzylinders 7 bzw. der Drückernuß 6 der Schieber 14 und über diesen die Steuerplatte 18 verlagert, wodurch die Treibstange 11 betätigt wird.If the change cylinder 12 and over the lock cylinder 7 this the control nut 16 in the direction of Actuated clockwise, then the arm 20 and the Latch foot 21, latch 8 in the main lock case 2 moved in. However, this can also be done in that the Handle nut 6 by means of a handle, not shown, in Is operated in the clockwise direction, the Handle nut 6, the control nut disk 16 during its rotational movement takes along. In addition, when the lock cylinder is actuated 7 or the follower 6 of the slide 14 and the latter Control plate 18 displaced, whereby the drive rod 11th is operated.

Mit dieser Treibstange 11 ist der Zusatzschließkasten 3 gemäß Figur 3 verbunden. In diesem, ohne Kastendeckel dargestellten Zusatzschließkasten 3 ist der Fallenriegel 10 in Richtung der Schnittlinie verschiebbar gelagert. Dieser Fallenriegel 10 befindet sich in den Figuren 3 und 4 in der Verriegelungsstellung, in der der Fallenriegel 10 mit seiner Auflaufschräge 22 (Figur 4) die Schloßstulpe 4 überragt und in eine Fallenöffnung 32 des Schließbleches 33 eingreift.With this drive rod 11 is the additional lock box 3rd connected according to Figure 3. In this, without box lid Additional locking case 3 shown is the latch bolt 10 Slidably mounted in the direction of the cutting line. This Latch bolt 10 is located in Figures 3 and 4 in the Locked position in which the latch bolt 10 with its ramp slope 22 (FIG. 4) the lock cuff 4 protrudes and into a latch opening 32 of the striking plate 33 intervenes.

In Figur 4 ist außerdem erkennbar, daß der Fallenriegel 10 mit einer in dessen Längsrichtung verlaufenden, einseitig offenen Nut 23 versehen ist. In dieser Nut 23 befindet sich ein Sperrelement 24, welches um eine Spannhülse 25 schwenkbar in der Nut 23 und somit im Fallenriegel 10 gelagert ist. Dieses Sperrelement 24 ist mit einer Sperrnase 26 sowie einer Auslösernase 27 versehen.In Figure 4 it can also be seen that the latch bolt 10th with one running in its longitudinal direction, one-sided open groove 23 is provided. Located in this groove 23 a locking element 24 which is around an adapter sleeve 25 pivotable in the groove 23 and thus in the latch bolt 10 is stored. This locking element 24 is with a Locking nose 26 and a trigger nose 27 provided.

Die Federkraft für den Fallenriegel 10 wird von einer Fallenausschubfeder 28 (Figur 3) aufgebracht, die auf einen Federführungsstift 29 aufgeschoben ist und sich einerseits an der Innenwand des Gehäuses des Zusatzschließkastens 3, andererseits an einem Fallenausschubhebel 30 abstützt. Dieser Fallenausschubhebel 30 ist in einem Lager 31 schwenkbar gelagert. Das dem Lager 31 gegenüberliegende Ende des Fallenausschubhebels 30 greift an dem der Auslösernase 27 gegenüberliegenden Ende des Sperrelements 24 an und drängt dieses unter der Kraft der Fallenausschubfeder 28 in Ausschubrichtung. Da das Sperrelement 24 über die Spannhülse 25 mit dem Fallenriegel 10 verbunden ist, wird auch dieser in Ausschubrichtung gedrängt.The spring force for the latch bolt 10 is from a Trap extension spring 28 (Figure 3) applied to a Spring guide pin 29 is pushed on and one hand on the inner wall of the housing of the additional locking box 3, on the other hand supported on a latch extension lever 30. This latch extension lever 30 is in a bearing 31 pivoted. The one opposite the bearing 31 End of the latch extension lever 30 engages the Trigger nose 27 opposite end of the locking element 24 and pushes it under the power of Latch extension spring 28 in the extension direction. Since that Locking element 24 via the clamping sleeve 25 with the latch bolt 10 is connected, this is also in the extension direction crowded.

In Figur 4 ist erkennbar, daß der Fallenausschubhebel 30 zwar am Sperrelement 24 angreift, die Richtung der Kraft des Fallenausschubhebels 30 jedoch nicht durch die von der Spannhülse 25 gebildete Schwenklagerung des Sperrelements 24 geht, so daß der Fallenausschubhebel 30 ein Schwenkmoment entgegen des Uhrzeigersinns auf das Sperrelement 24 ausübt. Aufgrund dieses Schwenkmoments werden die Sperrnase 26 sowie die Auslösernase 27 aus der Nut 23 ausgehoben.It can be seen in FIG. 4 that the latch extension lever 30 attacks the locking element 24, the direction of the force the latch extension lever 30, however, not by the Adapter sleeve 25 formed pivot bearing of the locking element 24 goes so that the latch extension lever 30 Swing moment counterclockwise on the Locking element 24 exercises. Because of this swing moment the locking lug 26 and the trigger lug 27 from the Groove 23 excavated.

Beim Zuschlagen bzw. Zudrücken der Tür wird der Fallenriegel 10 über das Schließblech 33 (Figur 4) in den Zusatzschließkasten 3 eingeschoben.When the door slams or closes, the Latch bolt 10 via the striking plate 33 (FIG. 4) in the Additional lock box 3 inserted.

Befindet sich die Tür in ihrer Schließstellung und fluchtet der Fallenriegel 10 zur Fallenöffnung 32 im türrahmenseitigen Schließblech 33 (Figur 4), wird der vollständig eingeschobene Fallenriegel 10 über den Fallenausschubhebel 30 aus dem Zusatzschließkasten 3 ausgeschoben. Während dieser Ausschubbewegung wird gleichzeitig das Sperrelement 24 entgegen der Richtung des Uhrzeigersinns um die Spannhülse 25 verschwenkt. Dabei kommt die Auslösernase 27 mit dem ihr zugewandten Rand der Fallenöffnung 32 des Schließbleches 33 in Kontakt, wodurch das Sperrelement 24 entgegen dem Schwenkmoment in die Nut 23 so weit eingeschoben wird, daß die Sperrnase 26 an der Schloßstulpe 4 vorbeigleiten kann. Auf diese Weise wird eine Verriegelung des Fallenriegels 10 in der Fallenstellung gemäß Figur 1 verhindert, so daß der Fallenriegel 10 in die in den Figuren 3 und 4 dargestellte Verriegelungsstellung ausfahren kann. In dieser Verriegelungsstellung ist der Fallenriegel 10 etwa 10 mm bis 15 mm weiter aus dem Zusatzschließkasten 3 ausgefahren, als in der Fallenstellung gemäß Figur 1.The door is in its closed position and in alignment the latch bolt 10 to the latch opening 32 in Strike plate 33 on the door frame side (FIG. 4) fully inserted latchbolt 10 over the Latch extension lever 30 from the additional lock box 3 pushed out. During this extension movement at the same time the locking element 24 against the direction of Pivoted clockwise around the clamping sleeve 25. Here comes the trigger nose 27 with the edge facing it Trap opening 32 of the striking plate 33 in contact, whereby the locking element 24 against the pivoting moment in the groove 23 is inserted so far that the locking lug 26 on the Castle cuff 4 can slide past. That way a latch of the latch bolt 10 in the Trap position according to Figure 1 prevented, so that Latchbolt 10 in that shown in Figures 3 and 4 Can extend locking position. In this Locking position is the latch bolt 10 about 10 mm extended up to 15 mm further from the additional locking box 3, than in the trap position according to FIG. 1.

In einer weiteren Ausgestaltung kann der Fallenausschubhebel 30 nach dem Verschwenken des Sperrelements 24 direkt am Fallenriegel 10 anliegen und diesen in die Verriegelungsstellung ausfahren.In a further embodiment, the Trap extension lever 30 after pivoting the Locking element 24 bear directly on the latch bolt 10 and extend it into the locked position.

Wie aus Figur 3 ersichtlich, weist der Fallenschwanz 34 einen Vorsprung 35 auf. Ferner ist erkennbar, daß um einen Lagerbolzen 36 ein Fallensperrhebel 37 schwenkbar gelagert ist und über eine Sperrhebelfeder 38, die als Schenkelfeder ausgebildet ist, entgegen der Richtung des Uhrzeigersinns federbelastet ist. Befindet sich der Fallenriegel 10 in der vollständig ausgeschobenen Lage gemäß Figuren 3 und 4, d.h. in der Verriegelungsstellung, dann hintergreift eine Fallensperrkante 39 den Vorsprung 35. Es kann zwar zwischen dem Vorsprung 35 und der Fallensperrkante 39, wie in Figur 3 dargestellt, ein geringer Abstand bestehen, jedoch greift die Fallensperrkante 39 in den Verschiebeweg des Vorsprungs 35.As can be seen from FIG. 3, the trap tail 34 a projection 35. It can also be seen that around Bearing pin 36 a latch lock lever 37 pivotally mounted is and via a locking lever spring 38, which acts as a leg spring is formed, counterclockwise is spring loaded. The latch bolt 10 is in the fully extended position according to Figures 3 and 4, i.e. in the locked position, then engages behind Trap locking edge 39 the projection 35. It can be between the projection 35 and the trap locking edge 39, as in Figure 3 shown, there is a small distance, but is effective the trap locking edge 39 in the displacement path of the projection 35.

Wird nun der Fallenriegel 10 z.B. mittels eines Werkzeugs oder dergleichen in den Zusatzschließkasten 3 eingeschoben, kommt der Vorsprung 35 an der Fallensperrkante 39 zur Anlage und ein weiterer Einschub wird verhindert. Der Fallenriegel 10 ist also in seiner Verriegelungsstellung gegen ein Einschieben verriegelt.If the latch bolt 10 is now e.g. using a tool or the like inserted into the additional locking box 3, the projection 35 comes to the trap locking edge 39 System and a further insertion is prevented. Of the Latch bolt 10 is thus in its locked position locked against insertion.

Wird über die Treibstange 11 ein Fallenrückstellhebel 40, der mit seinem einen Arm 41 am freien Ende der Treibstange 11 und mit seinem anderen Arm 42 an einem weiteren Vorsprung 43 des Fallenschwanzes 34 anliegt, verschwenkt, greift eine Nase 44 des freien Endes des Arms 42 an einer Kulisse 45 des Fallensperrhebels 37 an (Figur 3) und hebt diesen aus seiner Verriegelungsstellung, in welcher die Fallensperrkante 39 den Vorsprung 35 hintergreift, so weit aus, daß die Fallensperrkante 39 aus dem Verschiebeweg des Vorsprungs 35 heraustritt. Außerdem liegt der Arm 42 am Vorsprung 43 an und zieht beim Verschwenken des Fallenrückstellhebels 40 den Fallenriegel 30 in den Zusatzschließkasten 3 ein. Ist der Fallenriegel 10 vollständig in den Kasten 3 eingezogen worden, kann die Tür geöffnet werden.If a trap reset lever 40, the one with his arm 41 at the free end of the drive rod 11 and with his other arm 42 on another Projection 43 of latch tail 34 abuts, pivoted, engages a nose 44 of the free end of the arm 42 on one Setting 45 of the latch lock lever 37 (Figure 3) and lifts this from its locking position, in which the Trap locking edge 39 engages behind the projection 35 so far from that the trap locking edge 39 from the displacement of the Projection 35 emerges. In addition, the arm 42 is on Projection 43 and pulls when pivoting the Latch return lever 40 the latch bolt 30 in the Additional lock box 3. Is the latch bolt 10 The door can be completely retracted into box 3 be opened.

Bei geöffneter Tür und in Ruhelage sich befindender Treibstange 11 wird der Fallenriegel 10 über den Fallenausschubhebel 30 so weit ausgeschoben, bis die Sperrnase 26 die Schloßstulpe 4 hintergreift und einen weiteren Ausschub verhindert.With the door open and in the rest position Drive rod 11, the latch bolt 10 on the Trap extension lever 30 extended until the Locking nose 26 engages behind the lock cuff 4 and one further extension prevented.

In Figur 3 ist deutlich erkennbar, dass der Fallenrückstellhebel 40 an seinem freien Arm 41 mit einem ersten Mitnehmer 46 versehen ist, über welchen der Fallenrückstellhebel 40 von der Treibstange 11 in die nicht dargestellte Fallenstellung bewegt wird. Ferner weist der Fallenrückstellhebel 40 an seinem freien Ende 41 einen zweiten Mitnehmer 47 auf, der von einem Anschweißteil 48 gebildet wird. Über dieses Anschweißteil 48 wird der Fallenrückstellhebel 40 beim Vorschließen des Hauptschlossriegels 9, wodurch die Treibstange 11 nach unten bewegt wird, in die Verriegelungsstellung verschwenkt. Da dies eine Zwangsbewegung ist, die lediglich durch die Kraft der Feder 28 unterstützt wird, wird der Fallenriegel 10 auf jeden Fall ausgeschoben.In Figure 3 it can be clearly seen that the Trap reset lever 40 on its free arm 41 with a is provided first driver 46, via which the Trap reset lever 40 from the drive rod 11 in the trap position shown is moved. Furthermore, the Trap reset lever 40 at its free end 41 a second driver 47, which is formed by a weld-on part 48 is formed. About this weld-on part 48 Latch reset lever 40 when closing the Main lock bolt 9, whereby the drive rod 11 after is moved down into the locking position panned. Since this is a compulsory movement, the only is supported by the force of the spring 28, the Latch bolt 10 definitely pushed out.

Beim Vorschließen des Hauptschlossriegels 9 greift ein Fortsatz 49 des Hauptschlossriegels 9, der an seiner der Treibstange 11 zugewandten Seite mit einer Abschrägung 50 versehen ist, an einer Schrägfläche 51 der Treibstange 11 an und treibt diese nach unten an.When locking the main lock bolt 9 intervenes Extension 49 of the main lock bolt 9, which at its the Driving rod 11 facing side with a bevel 50 is provided on an inclined surface 51 of the drive rod 11 and drives it down.
