Abstract

A self-locking lock with a bolt, a lock swing catch and an auxiliary swing catch, in which the bolt and lock swing catch move out in a locking position in spring-loaded manner with the door closed and move out in a locking position are lockable by a slide plate, while the auxiliary swing catch pressed on a locking plate and in which the bolt, with the door open, is held back in the lock housing and is arrestable by the auxiliary swing catch by means of the slide plate. In order to provide a lock secure against manipulation and reliable in operation, where an uncontrollable extension of the bolt is particularly effectively prevented even in intermediate states of the opening and closing process, on opening the bolt leads compared with the lock swing catch and is arrestable completely retracted in the lock and the lock swing catch is provided with a widening, e.g., with a pivotable, springloaded swing catch part. As a result the lock swing catch engages longer on the locking plate and lags behind the auxiliary swing catch, so that the slide plate and bolt are arrested until the auxiliary swing catch arrests the slide plate and bolt. The lock swing catch widening has no effect on closing.

Description

Die Erfindung betrifft ein selbstverriegelndes Schloß gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a self-locking lock according to the preamble of claim 1.

Aus der DE 44 07 244 C1 ist ein selbstverriegelndes Schloß mit einem Wechsel, einem durch eine Feder in die Schließstellung bewegbaren Riegel, einer Falle und einer Hilfsfalle bekannt, bei dem der über eine geteilte Drückernuß oder einen Schließzylinder betätigbare Riegel über eine Raste, welche über die Hilfsfalle auslösbar ist, in der Offenstellung arretierbar ist. Ein selbsttätiges Ausfahren des Riegels bei offnem Türflügel wird dadurch verhindert, daß ein von der Falle gesteuerter, zweiter Schwenkhebel zur Blokkierung der Hilfsfalle vorgesehen und die Hilfsfalle in der ausgefahrenen Lage durch den Schwenkhebel blockiert ist, wenn die Falle ebenfalls ausgefahren ist.DE 44 07 244 C1 is a self-locking lock with a change, one by a spring in the closed position movable latch, a latch and an auxiliary latch known in which the over a split follower or a lock cylinder operated latch via a catch, which can be triggered via the auxiliary trap in the open position can be locked. An automatic extension of the latch when the door leaf is open, this prevents a from the trap controlled, second swivel lever for blocking the auxiliary trap provided and the auxiliary trap in the extended position is blocked by the swivel lever, if the trap is also extended.

Obwohl sich dieses Schloß in der Praxis voll bewährt hat, kann es im ungünstigsten Fall geschehen, daß bei Zwischenzuständen der Riegel ausfährt, jedoch nicht in die Öffnung des Schießblechs gelangt. Dies kann z.B. bei einem unkontrollierten Schließen und zu starken Türdichtungen durch ein Zurückfedern der Tür geschehen. Nicht vollständig auszuschließen sind auch Störungen, wenn bei einer berechtigten Türöffnung von außen der Türdrücker nicht bis zur vollständigen Öffnung der Tür niedergedrückt bleibt und der Riegel wieder vorschließt ohne in das Schließblech einrasten zu können. Although this lock has proven itself in practice, in the worst case it can happen that in intermediate states the latch extends, but not into the opening of the shooting plate. This can e.g. with an uncontrolled Close and strong door seals the door spring back. Not completely excluded are also disruptions when at a legitimate Doors open from the outside of the lever handles not completely Opening of the door remains depressed and the Bolt pre-closes again without snapping into the striking plate to be able to.

Bei einem in der EP 0 668 425 A1 beschriebenen selbstverriegelnden Türschloß ist ein Riegel in einer Führungskulisse einer Schubstange geführt, wobei die Schubstange linear gegen die Kraft einer Vorspannfeder verschiebbar ist und dabei der Riegel in das Schloß eingezogen wird. Ein Gesperre, welches z.B. einen an der Schubstange angeordneten Sperrstab und eine kippbar gelagerte Sperrplatte aufweist, greift derart an der Schubstange an, daß der Riegel in jeder Rückzugposition arretierbar ist. Mit Hilfe eines aus dem Türschloß ragenden Positionsfühlers ist das Gesperre lösbar, wobei der Riegel unter Einwirkung der Vorspannfeder, welche auf die Schubstange wirkt, ausschließen kann.In the case of a self-locking device described in EP 0 668 425 A1 Door lock is a bolt in a guide setting guided a push rod, the push rod linear is displaceable against the force of a biasing spring and the bolt is drawn into the lock. A lock, which e.g. one arranged on the push rod Has a locking rod and a tiltable locking plate, attacks the push rod in such a way that the bolt in each Retreat position can be locked. With the help of one the locking device protruding from the door lock is the locking mechanism releasable, the bolt under the action of the bias spring, which acts on the push rod can exclude.

Dieses bekannte Schloß ist insbesondere für einbruchhemmende Schlösser mit mehreren gesperrten Riegeln vorgesehen.
Die lineare Schubstangenbewegung wird als besonders einfache Übertragung für die Nebenschlösser benutzt. Als nachteilig wird bei diesem Schloß angesehen, daß der Riegel im Endabschnitt seiner Rückzugsbewegung in jeder Rückzugsposition arretierbar ist, so daß der Riegel nicht vollständig in den Schloßkasten zurückgezogen ist und eine Tür nur bei einem entsprechend breitem Luftspalt zwischen Rahmen und Tür geöffnet werden kann.This known lock is intended in particular for burglar-resistant locks with several locked bolts.
The linear push rod movement is used as a particularly simple transmission for the secondary locks. It is considered a disadvantage of this lock that the bolt can be locked in the end section of its retraction movement in any retracted position, so that the bolt is not fully retracted into the lock case and a door can only be opened with a correspondingly wide air gap between frame and door.

Der Erfindung liegt die Aufgabe zugrunde, ein manipulations- und betriebssicheres selbstverriegelndes Schloß zu schaffen, bei welchem ein unkontrolliertes Ausfahren des Riegels in jeder Phase des Öffnungs- und Schließvorgangs besonders wirksam und in einer konstruktiv außerordentlich effizienten Weise verhindert wird.The invention has for its object to provide a tamper and reliable self-locking lock, in which an uncontrolled extension of the bolt is particularly effective and prevented in a structurally extremely efficient manner in each phase of the opening and closing process.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruchs 1 gelöst. Zweckmäßig und vorteilhafte Ausbildungen sind in den Unteransprüchen und in der Figurenbeschreibung enthalten. According to the invention the object is achieved by the features of the claim 1 solved. Practical and advantageous training are in the dependent claims and in the description of the figures contain.

Ein Grundgedanke der Erfindung besteht darin, die Mechanik eines Schlosses zum Zusammenwirken von Riegel, Schloßfalle und Hilfs- bzw. Steuerfalle derart auszubilden, daß der Riegel beim Öffnen gegenüber der Schloßfalle "voreilend" verstellbar ist. Der Riegel wird immer ganz in das Schloß zurückgezogen und im vollständig zurückgezogenen Zustand arretiert. Eine Schieberplatte, welche federnd vorgespannt ist und den Riegel und die Schloßfalle in ausgeschlossener Stellung gegen ein Zurückdrücken in das Schloß verriegelt und bei geöffneter Tür den Riegel über die Hilfsfalle, welche einen Sperrhebel blockiert, im Schloß zurückhält und so ein unbeabsichtigtes Auslösen des Riegels verhindert, ist linear, vorzugsweise in vertikaler Richtung verstellbar angeordnet und weist eine Kulissenführung zur beispielsweise 90° umgelenkten Verstellung eines Riegelbolzens auf.A basic idea of the invention is the mechanics a lock for the interaction of bolts, lock latch and training auxiliary or control trap such that the Bolt "leading" towards the lock latch when opened is adjustable. The bolt is always fully in the lock withdrawn and in the fully withdrawn state locked. A slide plate, which is spring biased is and the bolt and the lock latch in excluded Locked position against pushing back into the lock and with the door open, the bolt on the auxiliary latch, which blocked a locking lever, holds it back in the lock and such prevents the latch from being triggered unintentionally linear, preferably adjustable in the vertical direction and has a backdrop for example 90 ° deflected adjustment of a locking bolt.

Außerdem ist die Schieberplatte derart ausgebildet, daß diese von einer an der Schloßfalle angeordneten Fallenbuchse oder -rolle gehalten wird, wenn die Schloßfalle beim Öffnen der Tür in einem sogenannten Zwischenzustand auf der Vorderseite des Gegenstücks bzw. Schließblechs gleitet. Indem die Schieberplatte von der Rolle der Schloßfalle gehalten wird, wird der Riegel in seiner zurückgezogenen Stellung sicher und störungsfrei gehalten.In addition, the slide plate is designed such that this from a latch bushing arranged on the lock latch or roller is held when the lock latch when Opening the door in a so-called intermediate state on the Front of the counterpart or striking plate slides. By doing the slide plate held by the role of the lock latch the latch will be retracted in its Position kept safe and trouble-free.

Erfindungsgemäß wird eine Arretierung der Schieberplatte durch die Rolle der Schloßfalle in einem Zwischenzustand beim öffnen der Tür und eine manipulationsund betriebssichere Rückhaltung des Riegels in diesem Zwischenzustand durch eine definierte Ausbildung der Schloßfalle und Anordnung in Relation zu der Hilfs- bzw. Steuerfalle erreicht.According to the invention, the slide plate is locked by the role of the lock latch in an intermediate state when opening the door and a tamperproof and reliable Retention of the bolt in this intermediate state through a defined design of the lock latch and arrangement achieved in relation to the auxiliary or tax trap.

Gemäß der Erfindung wird eine Schloßfalle eingesetzt, welche in einem vorgebbaren Zwischenzustand eine Verbreiterung aufweist. Die Verbreiterung kann z.B. durch eine mehrteilige, insbesondere eine zweiteilige Ausbildung, erreicht werden. Vorzugsweise weist die Schloßfalle wenigstens ein Fallenteil auf, welches verstellbar und derart gegenbelastet an der Schloßfalle angeordnet ist, daß diese im unbelasteten Zustand und bei Ansicht vom Schloßstulp her, breiter ist, beim öffnen in einer die Schloßfalle verbreiternden Stellung gehalten ist und dadurch länger an dem Schließblech anliegt.According to the invention, a lock latch is used, which a widening in a predeterminable intermediate state having. The broadening can e.g. through a multi-part, in particular a two-part training become. The lock latch preferably has at least one Case part, which is adjustable and counteracted in this way is arranged on the lock latch that this in the unloaded Condition and when viewed from the face plate, wider is when opening in a widening the lock latch Position is held and therefore longer on the Strike plate is present.

Beim öffnen der Tür, beispielsweise durch Betätigung eines Drückers von der Innenseite der Tür, bei berechtigtem Zugang durch Drückerbetätigung von der Außenseite her oder beim berechtigten Zugang mit einem Schlüssel durch Betätigung eines Profilzylinders, kann durch die erfindungsgemäße Ausbildung der Schloßfalle, falls die Tür nur etwas geöffnet und der Türdrücker wieder losgelassen wird, die Schloßfalle aufgrund ihrer Breite nur bis auf die Oberfläche des Gegenstückes bzw. Schließbleches ausschließen. Dadurch wird die Schieberplatte von der an der Schloßfalle in einer vorgebbaren Position angeordneten Rolle gehalten, wodurch der Riegel im Schloß zurückgehalten wird. Ein unkontrolliertes Ausschließen des Riegels ist durch die in dieser Stellung arretierte Schieberplatte nicht möglich.When opening the door, for example by pressing a Handle from the inside of the door, with authorized access by pressing the button from the outside or with authorized access with a key by actuation a profile cylinder, can by the invention Formation of the lock latch if the door is only slightly opened and the lever handle is released, the lock latch due to their width only up to the surface of the Exclude counterpart or striking plate. This will the slide plate of the on the lock latch in a predetermined Positioned roller held, whereby the Bolt is held back in the castle. An uncontrolled Exclude the bolt is by in this position locked slide plate not possible.

Wenn die Tür weiter geöffnet wird, gelangt die Hilfsfalle bis an das Gegenstück, wodurch eine an der Schieberplatte im Bereich der Hilfsfalle vorgesehene Nase in Eingriff mit der Hilfsfalle gelangt, so daß die gesamte Schieberplatte an einer Verstellung nach vertikal unten weiter gehindert wird. Der Riegel bleibt auf diese Weise in der im Schloß zurückgezogenen Stellung. Beim weiteren öffnen der Tür wird dann auch die Schloßfalle ausgefahren. Da die Hilfsfalle, z.B. durch einen Sperrhebel, weiter blockiert ist, kann der Riegel in keiner Weise unbeabsichtigt ausgelöst werden. If the door is opened further, the auxiliary latch arrives up to the counterpart, creating one on the slide plate provided in the area of the auxiliary trap in engagement with the auxiliary trap arrives, so that the entire slide plate further prevented from moving vertically downwards becomes. In this way, the bolt stays in the lock withdrawn position. When the door is opened further then the lock latch also extended. Since the auxiliary trap, e.g. is blocked by a locking lever, the Latches are in no way triggered unintentionally.

Beim Schließen der Tür gelangt zunächst die Schloßfalle mit dem schwenkbaren Fallenteil an eine Kante des Schließblechs. Das Fallenteil ist derart gegenbelastet, z.B. durch eine Schenkelfeder, daß es in die Schloßfalle zurückgedrückt bzw. geschwenkt wird. Danach gelangt die Hilfsfalle, welche zweckmäßigerweise die gleiche Abschrägung oder keilförmige Ausbildung aufweist wie die Schloßfalle und das Fallenteil, in Eingriff mit der Kante des Schließblechs und löst über einen Sperrhebel die Schieberplatte aus der Raststellung. Über eine Steuerkurve an der Schieberplatte gelangt diese jedoch in Eingriff mit der Rolle der Schloßfalle und wird dadurch an einer vertikalen Rückverstellung gehindert, bis die Schloßfalle in die entsprechende Öffnung des Schließblechs vorschließen kann. Erst dann kann die Schieberplatte verstellt werden und der Riegel über die Kulissenführung und einen darin geführten Riegelstift vorschließen, so daß die Grundstellung bei geschlossener Tür mit ausgeschlossenem Riegel und ausgeschlossener Schloßfalle sowie am Schließblech angedrückter Hilfs- bzw. Steuerfalle erreicht ist.When the door is closed, the lock latch comes first the pivoting latch part to an edge of the striking plate. The trap part is counter-loaded in this way, e.g. by a leg spring that it is pushed back into the lock latch or is pivoted. Then the Auxiliary trap, which expediently the same bevel or has a wedge-shaped design like the lock latch and the trap member, engaging the edge of the Striking plate and releases the slide plate via a locking lever from the rest position. Via a control curve on the But slide plate comes into engagement with the Role of the lock latch and is thereby on a vertical Readjustment prevented until the lock latch fits into the corresponding Can pre-open the striking plate. Only then can the slide plate be adjusted and the Latch over the scenery guide and a guided in it Lock the locking pin so that the home position is closed Door with bolt and bolt excluded Lock latch as well as pressed on the striking plate Aid or tax trap is reached.

Eine besonders vorteilhaft ausgebildete und mit der Hilfsfalle und der Schieberplatte zusammenwirkende Schloßfalle mit Verbreiterung wird in der Figurenbeschreibung weiter erläutert.A particularly advantageous trained and with the auxiliary trap and the latch plate cooperating with the slide plate with widening is further in the description of the figures explained.

Die Schieberplatte ist zumindest bereichsweise an einer Innenfläche des Schloßstulps geführt. Im Bereich der Hilfsfalle weist die Schieberplatte eine Langlochführung auf, in welcher ein gehäuseseitig angeordneter Bolzen für den Sperrhebel der Hilfsfalle angeordnet ist. Die Schieberplatte ist in einer Ausnehmung der Hilfsfalle geführt und über eine Rastnase an dieser arretierbar. Im Bereich der Schloßfalle und der auf der Schloßfalle angeordneten Fallenbuchse bzw. Rolle ist die Schieberplatte mit einer vorzugsweise bogenförmigen Ausnehmung versehen, in welcher die Rolle aufgenommen ist, wenn Riegel und Schloßfalle zur Türöffnung zurückgezogen, d.h. in dem Schloßgehäuse aufgenommen sind.The slide plate is at least in regions on an inner surface of the castle cuff. In the area of the auxiliary trap the slide plate has an elongated hole guide, in which is a housing-side bolt for the locking lever the auxiliary trap is arranged. The slide plate is guided in a recess of the auxiliary trap and over a Locking nose lockable on this. In the area of the lock latch and the latch bushing arranged on the lock latch or roller is the slide plate with a preferably arcuate recess in which the role is included when bolt and lock latch for opening the door withdrawn, i.e. are accommodated in the lock housing.

Die Verstellung der Schloßfalle kann über einen Fallenhebel und ein an sich bekanntes Hebelgestänge, welches direkt oder indirekt auch mit der Schieberplatte in Wirkverbindung steht und diese in vertikaler Richtung gegen die Kraft einer Zugfeder verstellt, erfolgen.The lock latch can be adjusted using a latch lever and a lever linkage known per se, which directly or indirectly also in operative connection with the slide plate stands and this in the vertical direction against the force of one Tension spring adjusted, done.

Das selbstverriegelnde Schloß ist außerdem über einen Schlüssel und einen Zylinderblock und einen Wechsel zu öffnen. Der Zylinderbart gelangt z.B. mit einer Ausformung der Schieberplatte zur Betätigung des Riegels und mit einem Wechsel in Eingriff, welcher die Falle in das Schloßgehäuse zurückzieht.The self-locking lock is also over one Keys and a cylinder block and a change to to open. The cylinder beard comes e.g. with a shape the slide plate for actuating the bolt and with a Change in engagement, which the latch in the lock housing withdraws.

Wesentliche Vorteile des erfindungsgemäßen Schloßes sind eine außerordentlich hohe Sicherheit gegen Manipulationen und Störungen in kritischen Zwischenstellungen bzw. Handhabungen und gleichzeitig eine besonders effiziente und raumsparende Mechanik bei Gewährleistung eines versicherungsrechtlich relevanten Riegelausschlußes für selbstverriegelnde Schlösser.The main advantages of the lock according to the invention are extremely high security against manipulation and malfunctions in critical intermediate positions or handling and at the same time a particularly efficient and space-saving Mechanics when ensuring an insurance law relevant bolt exclusion for self-locking Castles.

Der Bolzen 19 bildet die Schwenkachse für einen Sperrhebel 20, welcher nahezu rechtwinklig ausgebildet ist und mit einem oberen Hebelarm 21 zur Arretierung der Hilfsfalle 6 und mit einem unteren Hebelarm 22 in Wirkverbindung mit der Schloßfalle 5 bringbar ist. Die Schieberplatte 12 weist im Bereich der Schloßfalle 5 eine Ausnehmung 38 auf, welche über eine Abschrägung 23 in eine nahezu senkrechte Steuerkante 24 übergeht, welche z.B. in der Grundstellung gemäß Fig. 1 an einer Rolle oder einer Fallenbuchse 25 der Schloßfalle 5 anliegt und die Schloßfalle im ausgeschlossenen Zustand verriegelt. Die Sperrung des Riegels 4 wird über die Kulissenführung 15, die etwa in einem Winkel von 45° zur Vertikalen verläuft, vorgenommen. Der Riegelbolzen 10 ist dann in einer Endlage gehalten. The slide plate 12 is in the area of the auxiliary trap 6 a vertical slot opening 18 and is in a recess 37 of the auxiliary trap 6, wherein in the Slot opening 18 a bolt 19 is mounted. The bolt 19 forms the pivot axis for a locking lever 20, which is formed almost at right angles and with an upper Lever arm 21 for locking the auxiliary latch 6 and with a lower lever arm 22 in operative connection with the lock latch 5 is feasible. The slide plate 12 has in the area of Lock latch 5 has a recess 38 which has a Bevel 23 in an almost vertical control edge 24 passes, which e.g. in the basic position according to FIG. 1 on a roller or a case bush 25 of the lock case 5 is present and the lock latch in the locked state locked. The locking of bolt 4 is on the backdrop guide 15, which is approximately at an angle of 45 ° Vertical runs, made. The locking bolt 10 is then held in an end position.

Bei Betätigung des Türschlosses über die Drückernuß 7 wird ein Transporthebel 29 über eine an sich bekannte, nicht dargestellte Mechanik verschwenkt. Der Transporthebel 29 ist mit der Schieberplatte 12 verbunden und verstellt diese in vertikaler Richtung. Sowohl die Schloßfalle 5 als auch die Hilfsfalle 6 sind in Richtung der ausgeschlossenen Stellung federvorgespannt. Die Schloßfalle 5 wird über einen Fallenhebel 30, welcher um einen gehäuseseitigen Bolzen 35 schwenkbar gelagert ist (siehe Fig. 2 und 5), bei Betätigung der Drückernuß 7 über die Mechanik (nicht dargestellt) verstellt.When the door lock is operated using the follower 7 is a transport lever 29 via a known, Mechanism not shown pivoted. The transport lever 29 is connected to the slide plate 12 and adjusted this in the vertical direction. Both the lock latch 5 and the auxiliary trap 6 are in the direction of the excluded Spring-loaded position. The lock latch 5 is via a latch lever 30 which is around a housing side Bolt 35 is pivotally mounted (see Fig. 2nd and 5), when actuating the follower 7 via the mechanics (not shown) adjusted.

In Figur 2 ist das Schloß bei Betätigung von der Innenseite, d.h in Panikfunktion, gezeigt. Identische Merkmale sind mit identischen Bezugszeichen versehen. Bauteile, welche zum Verständnis der Erfindung nichts beitragen, wurden weggelassen. Dies trifft auch für die anderen Figuren zu.In Figure 2, the lock is actuated from the inside, i.e. shown in a panic function. Identical characteristics are provided with identical reference symbols. Components which contribute nothing to the understanding of the invention omitted. This also applies to the other figures.

Bei Betätigung der Drückernuß 7 durch einen Türdrücker innen und Drehung um etwa 35° werden der Riegel 4 und die Schloßfalle 5 zurückgezogen, wobei der Riegel 4 der Schloßfalle 5 voreilt. Die Verstellung von Riegel 4 und Schloßfalle 5 erfolgt über die nicht gezeigte Mechanik und den Transporthebel 29 und die Schieberplatte 12 bzw. den Fallenhebel 30. Die Tür kann dann geöffnet werden. Wenn die Tür nicht geöffnet und der Türdrücker losgelassen wird, so schließen Riegel 4 und Schloßfalle 5 wieder vor und verschließen die Tür (siehe Fig. 1).When the follower 7 is actuated by a lever handle inside and rotation by about 35 °, the bolt 4 and the Lock latch 5 withdrawn, the bolt 4 of the lock latch 5 advanced. The adjustment of bolt 4 and lock latch 5 takes place via the mechanics not shown and the Transport lever 29 and the slide plate 12 and the Latch lever 30. The door can then be opened. If the Door is not opened and the lever handle is released, so close bolt 4 and lock latch 5 again and close the door (see Fig. 1).

Figur 3 zeigt das Schloß bei geöffneter Tür, bei welcher die Hilfsfalle 6 und die Schloßfalle 5 aus dem Schloßstulp 2 vorstehen und der Riegel 4 im Schloß zurückgehalten und gegen unbeabsichtigtes Auslösen gesichert ist. Diese Sicherung erfolgt durch die Hilfsfalle 6, welche durch den oberen Hebelarm 21 des Sperrhebels 20 blockiert ist und über eine Rastnase 31 die Schieberplatte arretiert. Durch eine Relativbewegung der Schloßfalle 5 und der Hilfsfalle 6 wird die Hilfsfalle 6 über den Sperrhebel 20 entriegelt und der Riegel 4 kann aufgrund der nach unten verstellten Schieberplatte 12 beim Zumachen der Tür federbelastet und selbstverriegelnd verschließen.Figure 3 shows the lock with the door open, in which the auxiliary trap 6 and the lock trap 5 from the lock faceplate 2 protrude and the bolt 4 held in the lock and is secured against unintentional triggering. This backup takes place through the auxiliary trap 6, which through the upper Lever arm 21 of the locking lever 20 is blocked and over a latch 31 locks the slide plate. By a Relative movement of the lock latch 5 and the auxiliary latch 6 is the auxiliary latch 6 unlocked via the locking lever 20 and the Bolt 4 can due to the slider plate adjusted downwards 12 spring-loaded and self-locking when closing the door close.

Figur 4 zeigt eine Betätigung von der Außenseite bei geschlossener Tür. Da ein berechtigter Zugang nicht vorliegt, befindet sich der Türdrücker bzw. die Drückernuß außen 7 in Freilauffunktion. Der Türdrücker außen kann dann bis ca. 35° niedergedrückt werden und leerlaufen. Der Riegel 4 und die Schloßfalle 5 werden bei der Freilauffunktion nicht bewegt und das Schloß bleibt somit verriegelt.Figure 4 shows an actuation from the outside when closed Door. Since there is no authorized access, is the door handle or the follower outside 7 in Freewheel function. The lever handle on the outside can then Be depressed 35 ° and run empty. The latch 4 and the lock latch 5 are not in the freewheel function moves and the lock remains locked.

Figur 5 zeigt das Schloß bei Betätigung von der Außenseite bei berechtigtem Zugang, beispielsweise mit einem Zutrittkontrollsystem. In diesem Fall kann beispielsweise der Türdrücker bzw. die Drückernuß 7 elektrisch durch einen Hubmagneten mit dem Türdrücker innen gekuppelt werden (nicht dargestellt). Durch die Kupplung werden der Riegel 4 und die Schloßfalle 5 über die Panikseite durch Drehen des Türdrückers außen in das Schloß zurückgenommen (siehe Fig. 2). Die Tür kann geöffnet werden.Figure 5 shows the lock when actuated from the outside with authorized access, for example with an access control system. In this case, for example Door handle or the handle follower 7 electrically by a Solenoids can be coupled with the door handle on the inside (not shown). Through the coupling, the bolt 4 and the lock latch 5 on the panic side by turning the Door handle withdrawn into the outside of the lock (see Fig. 2). The door can be opened.

In Figur 6 ist eine Betätigung des Schlosses mit einem schlüsselbetätigbaren Schließsystem 8 gezeigt. Durch Drehen des Schließsystems 8 mit Schließnase 9 wird der Riegel 4 über die Schieberplatte 12 sowie die Schloßfalle 5 über einen Wechsel 36 in das Schloßgehäuse zurückgezogen. Die Tür kann dann geöffnet werden. In Figure 6 is an actuation of the lock with a key-operated locking system 8 shown. Go berserk the locking system 8 with the locking lug 9 becomes the bolt 4 via the slide plate 12 and the lock latch 5 via a Change 36 withdrawn into the lock housing. The door can then be opened.

Figur 7 zeigt einen Zwischenstand des Schlosses nach Fig. 1 bis 6 beim öffnen und Schliessen einer Tür, wobei dieser Zwischenzustand über die in den Figuren 8 bis 11 gezeigte Schloßfalle 5 mit Verbreiterung 40 und mit einer Rolle 25 und der definierten Anordnung der Schloßfalle 5 relativ zur Hilfsfalle 6 und zur Schieberplatte 12 erreicht wird. Die Schloßfalle 5 gleitet auf der Vorderseite des Schließblechs 16. Die Schieberplatte 12 wird dabei von der Rolle 25 der Schloßfalle 5 gehalten und hält gleichzeitig den Riegel 4 in der zurückgezogenen Stellung. Ein unbeabsichtigtes Vorschießen des Riegels 4 ist nicht möglich.FIG. 7 shows an intermediate status of the lock according to FIG. 1 to 6 when opening and closing a door, this one Intermediate state over that shown in Figures 8 to 11 Lock latch 5 with widening 40 and with a roller 25 and the defined arrangement of the lock latch 5 relative to Auxiliary trap 6 and the slide plate 12 is reached. The Lock latch 5 slides on the front of the striking plate 16. The slide plate 12 is from the roller 25 Lock latch 5 held and at the same time holds the bolt 4 in the retracted position. An accidental advance the bolt 4 is not possible.

Die Figuren 8.1 bis 8.3 zeigen in einer Draufsicht auf ein Schloß gemäß Fig. 7 einen Vorgang beim Öffnen einer Tür im Bereich der Schloßfalle 5 mit Verbreiterung 40 und einer Hilfsfalle 6. Ein Pfeil A gibt die Öffnungsrichtung einer Tür an. Riegel 4 und Schloßfalle 5 werden, wie im Zusammenhang mit den Figuren 2, 5 oder 6 beschrieben, zurückgezogen. Wird die Tür etwas geöffnet und der Türdrücker wieder losgelassen, so kann die Schloßfalle 5 aufgrund der Verbreiterung 40 nur bis auf die Oberfläche des Schließblechs 16 ausschließen (Fig. 8.1). Dabei wird die Schieberplatte 12 an der Abschrägung 23 von der Rolle 25 der Schloßfalle 5 gehalten und der Riegel 4 bleibt in der zurückgezogenen Stellung im Schloß zurück (Fig. 7). Wird die Tür weiter geöffnet (Fig. 8.2), so fährt die Hilfsfalle 6 zuerst vor und fängt die Schieberplatte 12 und dadurch auch den Riegel 4 (siehe Fig. 3). Danach fährt auch die Schloßfalle 5 vor (Fig. 8.3) und der Zustand wie in Figur 3 ist gegeben. Der Vorlauf der Hilfsfalle 6 vor der Schloßfalle 5 bzw. deren Nachlauf gegenüber der Hilfsfalle 6 wird durch die definierte Ausbildung der Schloßfalle 5 mit einem federbelasteten Fallenteil 40 als Verbreiterung (siehe auch Figur 10 und 11) bewirkt. Figures 8.1 to 8.3 show a plan view of a 7 closed a process when opening a door in Area of the lock latch 5 with widening 40 and one Auxiliary trap 6. An arrow A indicates the opening direction Door on. Bolt 4 and lock latch 5 are as related described with Figures 2, 5 or 6, withdrawn. The door is opened a little and the lever handle is opened again released, the lock latch 5 due to the widening 40 only down to the surface of the striking plate Exclude 16 (Fig.8.1). The slide plate 12 on the bevel 23 from the roller 25 of the lock latch 5 held and the bolt 4 remains in the retracted Position in the lock back (Fig. 7). The door continues opened (Fig. 8.2), the auxiliary trap 6 moves first and catches the slide plate 12 and thereby also the bolt 4 (see Fig. 3). Then the lock latch 5 also moves forward (Fig. 8.3) and the state as in Figure 3 is given. The Advance of the auxiliary trap 6 in front of the lock trap 5 or its Caster over the auxiliary trap 6 is defined by the Training the lock latch 5 with a spring-loaded Trap part 40 as a widening (see also Figure 10 and 11).

Beim Schließvorgang einer Tür (siehe Fig. 9.1 bis 9.3 mit Schließrichtung gemäß Pfeil B) wird die Schloßfalle 5 mit Verbreiterung 40 zunächst durch eine Kante eines Schließblechs 16 zurückgedrückt, wobei dies vom Türspalt, welcher ca. 4 bis 1 mm betragen kann, abhängig ist (Fig. 9.1). Fig. 9.1 und 9.2 verdeutlichen, daß die Verbreiterung 40 dabei nicht wirksam wird, da sie verschwenkt und von der Schloßfalle 5 aufgenommen wird. Danach löst die Hilfsfalle 6, welche ebenfalls an der Kante des Schließblechs 16 anliegt (Fig. 9.2), die Schieberplatte 12 aus. Die Schieberplatte 12 wird jedoch noch von der Rolle 25 solange zurückgehalten (Fig. 7), bis die Schloßfalle 5 im Schließblech 16 vorschließen kann (siehe Fig. 9.3). Danach kann auch der Riegel 5 vorschließen. Es ist dann der Schließzustand gemäß Figur 1 erreicht.When closing a door (see Fig. 9.1 to 9.3 with Lock direction according to arrow B), the lock latch 5 with Widening 40 initially by an edge of a striking plate 16 pushed back, this from the door gap, which approx. 4 to 1 mm, depending on (Fig.9.1). 9.1 and 9.2 illustrate that the widening 40 is not effective since it is pivoted and by the Castle latch 5 is added. Then the auxiliary trap releases 6, which also abuts the edge of the striking plate 16 (Fig. 9.2), the slide plate 12. The slide plate However, 12 is still held back by the roller 25 (Fig. 7) until the lock latch 5 in the striking plate 16 can close (see Fig. 9.3). Then the Close latch 5. It is then according to the closed state Figure 1 reached.

Die Schloßfalle 5 gemäß den Figuren 8 und 9 ist in den Figuren 10 und 11 vergrößert und ohne Hilfsfalle dargestellt. Die Schloßfalle 5 besteht aus einem Grundkörper 39 und weist zur Verbreiterung ein schwenkbares Fallenteil 40 auf, welches derart gegenbelastet ist, daß es beim Schließen und Andrücken an ein Schließblech 16 (s. Fig. 9.1) verschwenkt und vom Grundkörper 39 aufgenommen wird. Beim Öffnen verbleibt das federbelastete Fallenteil 40 in der den Grundkörper 39 verbreiternden Stellung (s. Fig. 8.1 bis 8.3) und gewährleistet das längere Anliegen an dem Schließblech 16 und das Zusammenwirken der Rolle 25 mit der Schieberplatte 12 (s. Fig. 7).The lock latch 5 according to Figures 8 and 9 is in the figures 10 and 11 enlarged and shown without an auxiliary trap. The lock latch 5 consists of a base body 39 and has a pivotable latch part 40 for widening, which is counter-loaded so that when closing and Press on a striking plate 16 (see Fig. 9.1) pivoted and is received by the base body 39. Remains when opening the spring-loaded latch part 40 in the base body 39 widening position (see Fig. 8.1 to 8.3) and ensures longer contact with the striking plate 16 and the interaction of the roller 25 with the slide plate 12 (see Fig. 7).

Das Fallenteil 40 ist im vorliegenden Ausführungsbeispiel um eine vertikale Achse 41 schwenkbar angeordnet und verbreitert mit einem überstehenden Bereich 42, welcher über eine Keilfläche 43 des Grundkörpers 39 übersteht, die Schloßfalle 5 stulpseitig. Die Schloßfalle 5 weist im Übergang zwischen einem ausschließbaren Fallenbereich 44 und einem im Schloßgehäuse 3 geführten Fallenbereich 45, welcher mit einer Federaufnahme 46 für eine Druckfeder 48 (siehe z.B. Fig. 1) versehen ist, die Rolle bzw. Fallenbuchse 25 auf. An dieser Rolle 25 wird die Schieberplatte 12 mit ihrer Steuerkante 24 (Fig. 1) oder Abschrägung 23 (Fig. 7) gehalten, um eine vertikale Verstellung der Schieberplatte 12 und ein unerwünschtes Vorschließen des Riegels 4 in jedem Fall zu verhindern und Störungen sowie Beschädigungen am Schloß zu vermeiden.The case part 40 is in the present embodiment arranged and widened pivotably about a vertical axis 41 with a protruding area 42 which over a wedge surface 43 of the base body 39 protrudes Lock latch 5 faceplate. The lock latch 5 points in Transition between an exclusive trap area 44 and a latch area 45 guided in the lock housing 3, which with a spring receptacle 46 for a compression spring 48 (see e.g. Fig. 1) is provided, the roller or trap bush 25 on. On this roller 25, the slide plate 12 with its control edge 24 (FIG. 1) or bevel 23 (Fig. 7) held for vertical adjustment of the slide plate 12 and unwanted locking of the latch 4 to prevent in any case and malfunctions and damage to avoid at the castle.

Das verschwenkbare Fallenteil 40 ist im Querschnitt als ein gleichschenkliges Dreieck mit abgerundeten Ecken ausgebildet und durch eine am Zylinderstift 41 gelagerte Schenkelfeder 49 beaufschlagt. Das Fallenteil 40 steht im unbelasteten Zustand und bei einer auf eine Grundfläche 47 wirkenden Belastung aufgrund der Wirkung der Schenkelfeder 49 über die Keilfläche 43 vor und verbreitert die Schloßfalle 5, um deren Vorlauf vor der Hilfsfalle 6 beim Schließen zu erreichen (Fig. 9.1 bis 9.3). Beim Öffnen wird ein Vorlauf der Hilfsfalle 6 vor der Schloßfalle 5 derart, daß die verbreiterte Schloßfalle 5 länger als die Hilfsfalle 6 an dem Schließblech 16 anliegt, erreicht, indem das Fallenteil 40 durch die Schenkelfeder 49 vorstehend und unverschwenkbar gehalten wird.The pivotable latch part 40 is in cross section as one isosceles triangle with rounded corners and by a leg spring mounted on the cylinder pin 41 49 acted upon.
