  • the invention relates to a locking device with at least one bolt or the like. And with a lock for this bolt, which can be opened and closed by means of an assistant, preferably by means of an electromagnet.
  • a known locking device of this type is, for example, a time lock according to DE-PS 26 34 107.
  • the auxiliary force is applied by mechanical clockworks which open a lock after a set time by moving a recess into the area of the rod-shaped lock , so that the lock engages in this recess and thereby releases the bolt.
  • the bolt can then fall out of the area of a locking bar, so that the locking bar can be inserted into the time lock.
  • a weaker auxiliary force such as that which an electromagnet can apply, would not be sufficient to overcome the friction when moving the push rod with the recess in the area of the lock.
  • an electromagnet would not be able to move this push rod back into the locking position because the lock engages in the recess in its open position and prevents displacement.
  • locking devices are known from practice, for example on front doors, which are opened electromagnetically in that the closure part holding the door latch in the closed position is electromagnetically released. There is a risk that the locking part to be released electromagnetically can be jammed if the door is already loaded in the opening direction before the current pulse is applied to the electromagnet.
  • the solution to this problem consists essentially in the fact that the bolt has a bearing that allows two different bolt movements, one bolt movement when the lock is open to an open position of the bolt and the other bolt movement when the lock is closed and at - compared to the force required for the opening movement - greater load leads to a locking position of the bolt, and that a support for the bolt is provided in its blocking position, which support absorbs forces occurring in the event of an unwanted or unauthorized attempt to open the bolt, so that these forces are prevented from the lock. This ensures that such unwanted or unauthorized forces are not transferred to the lock, so that it can be easily moved back to its open position even when pressure is applied to the latch, so that a small auxiliary force is sufficient for this movement despite such loads.
  • the bolt can be moved on the one hand and pivoted on the other hand. In this way, the desired different bolt movements can be easily implemented.
  • the bolt can be in the pivoted position in the open position and in the shifted position in the blocking position and can act on the support. This is particularly useful in those applications in which a bolt or the like should be pivotable for the opening, as is known, for example, in time locks for releasing a push rod channel.
  • the lock can be arranged in the pivot path of the bolt in the region of a part that can be moved by pivoting the bolt, and laterally this part can be provided to support the bolt for its blocking position. If the bolt is prevented from moving in the open position by the lock, it is easily moved against the support when loaded and thus reaches its blocking position.
  • a particularly expedient and advantageous embodiment of the invention can consist in that a link or the like is arranged in the pivot path of the bolt, which converts the pivoting movement of the bolt into its open position into a linear movement against the lock. This enables a particularly simple and expedient design of the lock, since it is only ever acted upon from a defined direction.
  • a particularly useful embodiment of the lock can consist in the fact that the lock is designed as a toggle lever which buckles when the lock is released and is extended in the closed position.

  • the actuating lever can advantageously be actuated by this low auxiliary force even when the bolt is in the blocking position, because the loads then emanating from the bolt are absorbed by its support and are not passed on to the lock. It is thus possible for the actuating lever, which can be pivoted relative to the lock, to be pivoted back into the position corresponding to the closed position by means of the auxiliary force acting on it, even when the toggle lever is bent.

Description

Die Erfindung betrifft eine Verriegelungsvorrichtung mit wenigstens einem Riegel od. dgl. und mit einer Sperre für diesen Riegel, die mittels einer Hilfskraft, vorzugsweise mittels Elektromagnet, öffen- und schließbar ist.The invention relates to a locking device with at least one bolt or the like. And with a lock for this bolt, which can be opened and closed by means of an assistant, preferably by means of an electromagnet.

Derartige Verriegelungsvorrichtungen sind in unterschiedlichen Anwendungsfällen und Ausführungsformen bekannt.Such locking devices are known in different applications and embodiments.

Eine bekannte derartige Verriegelungsvorrichtung ist beispielsweise ein Zeitschloß gemäß DE-PS 26 34 107. In diesem Fall wird die Hilfskraft von mechanischen Uhrwerken aufgebracht, die nach Ablauf einer eingestellten Zeit eine Sperre dadurch öffnen, daß eine Ausnehmung in den Bereich der stangenförmig ausgebildeten Sperre verschoben wird, so daß die Sperre in diese Ausnehmung einfällt und dadurch den Riegel freigibt. Der Riegel kann dann aus dem Bereich einer Sperrstange herunterfallen, so daß die Sperrstange in das Zeitschloß eingeschoben werden kann. Eine schwächere Hilfskraft, wie sie ein Elektromagnet aufzubringen vermag, wäre dabei nicht ausreichend, die Reibung beim Verschieben der Schubstange mit der Ausnehmung im Bereich der Sperre zu überwinden. Außerdem wäre ein Elektromagnet auch nicht in der Lage, diese Schubstange wieder in Sperrstellung zurückzuverschieben, weil die Sperre in ihrer Offenstellung in die Ausnehmung eingreift und eine Verschiebung verhindert.A known locking device of this type is, for example, a time lock according to DE-PS 26 34 107. In this case, the auxiliary force is applied by mechanical clockworks which open a lock after a set time by moving a recess into the area of the rod-shaped lock , so that the lock engages in this recess and thereby releases the bolt. The bolt can then fall out of the area of a locking bar, so that the locking bar can be inserted into the time lock. A weaker auxiliary force, such as that which an electromagnet can apply, would not be sufficient to overcome the friction when moving the push rod with the recess in the area of the lock. In addition, an electromagnet would not be able to move this push rod back into the locking position because the lock engages in the recess in its open position and prevents displacement.

Ferner sind aus der Praxis Verriegelungsvorrichtungen beispielsweise an Haustüren bekannt, die elektromagnetisch dadurch geöffnet werden, daß das die Türfalle in Schließstellung haltende Verschlußteil elektromagnetisch gelöst wird. Dabei besteht die Gefahr, daß das elektromagnetisch zu lösende Verschlußteil verklemmt werden kann, wenn die Türe vor Aufbringen des Stromimpulses auf den Elektromagneten schon in Öffnungsrichtung belastet wird.Furthermore, locking devices are known from practice, for example on front doors, which are opened electromagnetically in that the closure part holding the door latch in the closed position is electromagnetically released. There is a risk that the locking part to be released electromagnetically can be jammed if the door is already loaded in the opening direction before the current pulse is applied to the electromagnet.

Es besteht deshalb die Aufgabe, eine Verriegelungsvorrichtung der eingangs erwähnten Art zu schaffen, bei welcher die Sperre bei jeder Belastungsart und Stellung des Riegels mit einer geringen Hilfskraft geöffnet oder auch geschlossen werden kann.It is therefore an object of the invention to provide a locking device of the type mentioned in the introduction, in which the lock can be opened or closed with a small auxiliary force for every type of load and position of the bolt.

Die Lösung dieser Aufgabe besteht im wesentlichen darin, daß der Riegel eine zwei unterschiedliche Riegelbewegungen zulassende Lagerung aufweist, wobei die eine Riegelbewegung bei geöffneter Sperre zu einer Offenstellung des Riegels und die andere Riegelbewegung bei geschlossener Sperre und bei - gegenüber der für die Öffnungsbewegung erforderlichen Kraft - größerer Belastung in eine Blockierstellung des Riegels führt, und daß eine Abstützung für den Riegel in seiner Blockierstellung vorgesehen ist, welche Abstützung bei einem ungewollten oder unbefugten Öffnungsversuch am Riegel auftretende Kräfte aufnimmt, so daß diese Kräfte von der Sperre abgehalten sind. Dadurch wird erreicht, daß solche ungewollt oder unbefugt erfolgten Kräfte nicht auf die Sperre übertragen werden, so daß diese selbst bei Druck auf den Riegel leicht in ihre Öffnungsposition zurückbewegt werden kann, so daß für diese Bewegung trotz solcher Belastungen eine geringe Hilfskraft genügt.The solution to this problem consists essentially in the fact that the bolt has a bearing that allows two different bolt movements, one bolt movement when the lock is open to an open position of the bolt and the other bolt movement when the lock is closed and at - compared to the force required for the opening movement - greater load leads to a locking position of the bolt, and that a support for the bolt is provided in its blocking position, which support absorbs forces occurring in the event of an unwanted or unauthorized attempt to open the bolt, so that these forces are prevented from the lock. This ensures that such unwanted or unauthorized forces are not transferred to the lock, so that it can be easily moved back to its open position even when pressure is applied to the latch, so that a small auxiliary force is sufficient for this movement despite such loads.

Zweckmäßig ist es, wenn der Riegel einerseits verschiebbar und andererseits verschwenkbar ist. Auf diese Weise sind die gewünschten unterschiedlichen Riegelbewegungen einfach realisierbar. Dabei kann der Riegel in verschwenkter Position in Offenstellung und in verschobener Position in Blockierstellung sein und die Abstützung beaufschlagen. Dies ist vor allem bei solchen Anwendungsfällen zweckmäßig, in denen ein Riegel od. dgl. für die Öffnung verschwenkbar sein soll, wie es beispielsweise in Zeitschlössern zur Freigabe eines Schubstangenkanales bekannt ist.It is expedient if the bolt can be moved on the one hand and pivoted on the other hand. In this way, the desired different bolt movements can be easily implemented. The bolt can be in the pivoted position in the open position and in the shifted position in the blocking position and can act on the support. This is particularly useful in those applications in which a bolt or the like should be pivotable for the opening, as is known, for example, in time locks for releasing a push rod channel.

Die Sperre kann im Schwenkweg des Riegels im Bereich eines durch die Schwenkung des Riegels bewegbaren Teiles angeordnet sein und seitlich dieses Teiles kann die Abstützung des Riegels für seine Blockierstellung vorgesehen sein. Ist der Riegel durch die Sperre an seiner Bewegung in Offenstellung gehindert, wird er bei Belastung auf einfache Weise gegen die Abstützung verschoben und gelangt so in seine Blockierstellung.The lock can be arranged in the pivot path of the bolt in the region of a part that can be moved by pivoting the bolt, and laterally this part can be provided to support the bolt for its blocking position. If the bolt is prevented from moving in the open position by the lock, it is easily moved against the support when loaded and thus reaches its blocking position.

Eine besonders zweckmäßige und vorteilhafte Ausführungsform der Erfindung kann darin bestehen, daß im Schwenkweg des Riegels eine Kulisse od. dgl. Schieber angeordnet ist, die die Schwenkbewegung des Riegels in seine Offenstellung in eine lineare Bewegung gegen die Sperre umwandelt. Dadurch ist eine besonders einfache und zweckmäßige Ausgestaltung der Sperre möglich, da diese immer nur aus einer definierten Richtung her beaufschlagt wird.A particularly expedient and advantageous embodiment of the invention can consist in that a link or the like is arranged in the pivot path of the bolt, which converts the pivoting movement of the bolt into its open position into a linear movement against the lock. This enables a particularly simple and expedient design of the lock, since it is only ever acted upon from a defined direction.

Eine besonders zweckmäßige Ausgestaltung der Sperre kann dadurch darin bestehen, daß die Sperre als Kniehebel ausgebildet ist, der beim Lösen der Sperre einknickt und in Schließstellung gestreckt ist. Dabei ist in vorteilhafter Weise ferner möglich, daß das dem Knicklager des Kniehebels abgewandte Lager des einen Armes des Kniehebels an der durch die Schwenkbewegung des Riegels verschiebbaren Kulisse angeordnet ist. Somit erhält einerseits der Kniehebel eine gute Lagerung und andererseits ergibt sich eine sichere und definierte Einleitung der jeweils zu übertragenden Kräfte, insbesondere der Sperrkräfte oder aber auch der beim Ausknicken des Kniehebels aufzubringenden Kräfte. Außerdem liegt durch die Führung der Kulisse auch die Bahn des daran vorgesehenen Kniehebellagers fest.A particularly useful embodiment of the lock can consist in the fact that the lock is designed as a toggle lever which buckles when the lock is released and is extended in the closed position. It is also possible in an advantageous manner that the bearing of one arm of the toggle lever facing away from the articulated bearing of the toggle lever is arranged on the link that can be displaced by the pivoting movement of the latch. Thus, on the one hand the toggle lever is well supported and on the other hand there is a safe and defined introduction of the forces to be transmitted in each case, in particular the blocking forces or also the forces to be exerted when the toggle lever is bent. In addition, the path of the toggle lever bearing provided is fixed by the guidance of the backdrop.

Eine Ausgestaltung der Erfindung von ganz erheblicher Bedeutung und großem Vorteil kann darin bestehen daß an dem Kniehebel ein durch die Hilfskraft schwenkbarer Betätigungshebel angreift, dessen Schwenklager in Ruhestellung des Kniehebels - in Sperrstellung - mit dem Knicklager vorzugsweise übereinstimmt und an dessen zweitem Ende der dem Riegel bzw. der Kulisse abgewandte Kniehebelarm der Sperre schwenkbar gelagert ist. Dadurch ist eine Weiterbildung möglich, bei welcher der Betätigungshebel zum Vorknicken des Kniehebels dient, so daß der vorgeknickte Kniehebel der Verschwenkung des Riegels in dessen Öffnungsstellung nachgibt. Dies erleichtert es, mit einer geringen Hilfskraft die Sperre zu betätigen. Dabei kann der Betätigungshebel von dieser geringen Hilfskraft in vorteilhafter Weise auch dann betätigt werden, wenn der Riegel sich in Blockierstellung befindet, weil die dann von dem Riegel ausgehenden Belastungen von seiner Abstützung aufgefangen und nicht auf die Sperre weitergeleitet werden. Somit ist es möglich, daß der relativ zu der Sperre schwenkbare Betätigungshebel mittels der an ihm angreifenden Hilfskraft in die der Schließstellung entsprechende Position auch bei geknicktem Kniehebel zurückschwenkbar ist. Somit kann das Einnehmen der Schließstellung der Sperre schon bei geöffnetem Riegel vorbereitet werden.An embodiment of the invention of very considerable importance and great advantage can be that an operating lever pivotable by the auxiliary force acts on the toggle lever, the pivot bearing of which is in the rest position The toggle lever - in the locked position - preferably corresponds to the articulated bearing and at its second end the toggle lever arm of the lock facing away from the bolt or the link is pivotably mounted. This enables a further development in which the actuating lever serves to bend the toggle lever forward, so that the pre-bent toggle lever yields to the pivoting of the bolt in its open position. This makes it easier to operate the lock with a small assistant. In this case, the actuating lever can advantageously be actuated by this low auxiliary force even when the bolt is in the blocking position, because the loads then emanating from the bolt are absorbed by its support and are not passed on to the lock. It is thus possible for the actuating lever, which can be pivoted relative to the lock, to be pivoted back into the position corresponding to the closed position by means of the auxiliary force acting on it, even when the toggle lever is bent. Thus, the closing position of the lock can be prepared even when the bolt is open.

Zweckmäßig ist es, wenn das Ausknicken des Kniehebels durch das Öffnen des Riegels entgegen einer den Kniehebel in Sperrstellung zurückführenden Rückstellkraft, insbesondere der durch die an dem Kniehebelarm angelenkte Kulisse od. dgl. wirkende Schwerkraft oder eine Feder und/oder eine zwischen dem Betätigungshebel und dem Kniehebel wirkende Feder erfolgt. Wird der Riegel aus seiner Öffnungsposition in seine Schließstellung zurückgeführt, kann also die Sperre selbsttätig in ihre Sperrposition gelangen insbesondere dann, wenn zuvor der Betätigungshebel schon zurückgeschwenkt wurde.It is expedient if the kinking of the toggle lever by opening the latch counter to a restoring force returning the toggle lever into the blocking position, in particular the force of gravity or a spring acting through the link articulated on the toggle lever arm or the like, or a spring and / or a between the actuating lever and the Spring toggle acting. If the bolt is returned from its open position to its closed position, the lock can automatically move into its locked position, particularly if the actuating lever has already been pivoted back.

Dabei ist es vorteilhaft, wenn die Rückstellfeder an dem Kniehebel als Schenkelfeder ausgebildet ist, die am Betätigungshebel einerseits und mit Abstand dazu nahe dem Knicklager an dem Kniehebelarm andererseits angreift und in geknickter Position des Kniehebels gespannt ist. Die vorherige Rückverschwenkung des Betätigungshebels sorgt für eine entsprechende Spannung an dieser Schenkelfeder, so daß beim Schließen des Riegels die Streckung des Kniehebels unterstützt wird.It is advantageous if the return spring on the toggle lever is designed as a leg spring which, on the one hand, engages the actuating lever and at a distance from it, close to the articulated bearing on the toggle lever arm, and is tensioned in the bent position of the toggle lever. The previous pivoting back of the actuating lever ensures a corresponding tension on this leg spring, so that the extension of the toggle lever is supported when the latch is closed.

Der Kniehebel kann in gestreckter Position entgegen der Ausknickrichtung einen vorzugsweise einstellbaren Anschlag aufweisen, um ein Ausknicken in falscher Richtung zu verhindern.The toggle lever can have a preferably adjustable stop in the extended position against the buckling direction in order to prevent buckling in the wrong direction.

Für die Seitwärtsbewegung des Riegels in seine Blockierstellung bei Belastung des Riegels bei geschlossener Sperre kann an dem Riegel ein Langloch vorgesehen sein, in welches in Ausgangsstellung ein auch als Schwenklager dienender Lagerstift angreift. Der Lagerstift kann im Langloch gleichzeitig den Anschlag für eine Rückstellkraft entgegen der Verschiebebewegung des Riegels, vorzugsweise eine Feder bilden. Dabei kann die Feder an ihrem dem Lagerstift zugewandten Ende ein den Lagerstift beaufschlagendes Lagerteil, vorzugsweise eine Lagerschale tragen, damit die Schwenkbewegung des Riegels in seine Offenstellung ungehindert und mit möglichst geringem Kraftaufwand erfolgen kann.For the sideways movement of the bolt into its blocking position when the bolt is loaded when the lock is closed, an elongated hole can be provided on the bolt, in which a bearing pin, which also serves as a pivot bearing, engages in the starting position. The bearing pin can simultaneously form the stop for a restoring force against the sliding movement of the bolt, preferably a spring, in the slot. The spring at its end facing the bearing pin can carry a bearing part which acts on the bearing pin, preferably a bearing shell, so that the pivoting movement of the bolt into its open position can take place unimpeded and with as little effort as possible.

Zur Vergrößerung der Stabilität der gesamten Verriegelungsvorrichtung und zur Verbesserung der Überleitung insbesondere der Blockierkräfte ist es zweckmäßig, wenn am der Kulisse abgewandten Ende des Riegels mit geringem Abstand zu diesem eine kreisbogenförmige Begrenzung vorgesehen ist, gegen welche das freie Ende des schwenkbaren Riegels in Blockierstellung der Sperre bei der Verschiebung des Riegels anläuft und sich zusätzlich abstützt und wenn zwischen dieser Begrenzung und dem Riegel bei seiner Schwenkbewegung ein Spalt freibleibt. Je geringer dabei die Weite dieses Spaltes gewählt wird, umso schneller stützt sich der Riegel bei Verschiebung in Blockierstellung auch an der kreisbogenförmigen Begrenzung ab. Somit ergibt sich eine Abstützung des Riegels nicht nur an der für seine Blockierstellung vorgesehenen Abstützung, sondern zusätzlich auch an dieser Begrenzung, so daß beispielsweise Reaktionskräfte auf den Lagerstift praktisch ausgeschlossen werden können.To increase the stability of the entire locking device and to improve the transfer, in particular the blocking forces, it is expedient if a circular arc-shaped boundary is provided on the end of the bolt facing away from the link, against which the free end of the pivotable bolt in the blocking position of the lock starts when the bolt moves and is additionally supported and if a gap remains free between this limitation and the bolt during its pivoting movement. The smaller the width of this gap is selected, the faster the bolt is also supported on the circular arc-shaped boundary when it is moved in the blocking position. This results in the bolt not only being supported on the support provided for its blocking position, but also also on this limitation, so that, for example, reaction forces on the bearing pin can be practically excluded.

Es sei noch erwähnt, daß zur Betätigung der Sperre mittels eines die Hilfskraft erzeugenden Elektromagneten ein elektronisches Uhrwerk vorgesehen sein kann. Dies ist vor allem bei Anwendung der Verriegelungsvorrichtung in einem Zeitschloß von Vorteil. Dabei ist es dann auch möglich, daß an dem freien verschwenkbaren Ende des Riegels eine stirnseitig insbesondere schräge Ausnehmung vorgesehen ist, die bei verschwenkter Position des Riegels in dessen Offenstellung in Fortsetzung des Eintrittskanales für die Sperrstange einer Tresortüre od. dgl. liegt.It should also be mentioned that an electronic clockwork can be provided for actuating the lock by means of an electromagnet generating the auxiliary power. This is particularly advantageous when the locking device is used in a time lock. It is then also possible that at the free pivotable end of the bolt an end face, in particular an oblique recess is provided, which lies in the pivoted position of the bolt in its open position in continuation of the entry channel for the locking rod of a safe door or the like.

Für die Funktion des Schlosses kann es vorteilhaft sein, wenn die Längserstreckung der Kniehebel-Sperre vertikal angeordnet und die Kulisse oberhalb des schwenkbaren Riegels auf- und abbewegbar geführt sind, so daß die Schwerkraft zum Strecken des Kniehebels dient oder beiträgt. Dadurch wird man zumindest teilweise unabhängig von Rückstellfedern od. dgl., deren Kräfte bei der Betätigung überwunden werden müssen und die gegebenenfalls eine Störquelle darstellen könnten.For the function of the lock, it can be advantageous if the longitudinal extension of the toggle lock is arranged vertically and the link above the pivotable latch can be moved up and down so that gravity serves or contributes to extending the toggle lever. This makes one at least partially independent of return springs or the like, the forces of which have to be overcome during actuation and which could possibly be a source of interference.

Eine besonders günstige Ausgestaltung der Erfindung insbesondere zur Verwendung an einem Zeitschloß, bei welchem der Riegel in Sperrstellung den Eintritt einer Sperrstange verhindert und bei gelöster Sperre der Sperrstange ausweicht, kann darin bestehen, daß der Stift im Langloch des Riegels mittig angeordnet ist und beidseitig gegen Druckfedern abgestützt ist und daß der Riegel aus einer mittleren Sperrstellung nach beiden Seiten in Offenstellungen schwenkbar oder beidseitig in Blockierstellungen verschiebbar ist und beidseitig einer mittleren verschiebbaren Kulisse od. dgl. Schieber Abstützungen für die Blockierstellung hat. Somit kann ein derartiges Zeitschloß sowohl für links als auch für rechts angeschlagene Türen Verwendung finden. Dabei genügt nach wie vor eine einzige Sperre, da die verschiebbare Kulisse sowohl beim Verschwenken des Riegels nach der einen als auch nach der anderen Seite in linearer Richtung gegen die Sperre hin verschoben wird. Auch in anderen Fällen, in denen einander entgegengesetzte Riegelbewegungen je nach Montage der Vorrichtung erforderlich sein können, kann die vorbeschriebene Ausgestaltung der Erfindung angewendet werden. Es ergibt sich dann für solche jeweils einander entgegengesetzte Montagestellungen eine rationellere Fertigung und Lagerhaltung.A particularly advantageous embodiment of the invention, in particular for use in a time lock, in which the bolt prevents the entry of a locking rod in the locked position and dodges the locking rod when the lock is released, can consist in that the pin is arranged centrally in the slot of the bolt and on both sides against compression springs is supported and that the bolt can be swiveled from both sides into an open position or displaced on both sides in blocking positions from a central locking position and on both sides of a central sliding link or the like. Slider supports for the blocking position. Thus, such a time lock can be used for both left and right hinged doors. In this case, a single lock is still sufficient, since the displaceable backdrop both when pivoting the bolt towards one and the other to the other side in a linear direction towards the lock. The above-described embodiment of the invention can also be used in other cases in which opposing locking movements may be required depending on the assembly of the device. This then results in more rational production and warehousing for such mutually opposite assembly positions.

Insgesamt ergibt sich vor allem bei Kombination einzelner oder mehrerer der vorbeschriebenen Merkmale und Maßnahmen eine Verriegelungsvorrichtung, bei welcher eine geringe Hilfskraft ausreicht, um die Sperre für den Riegel zu öffnen oder auch zu schließen, selbst wenn der Riegel selbst ungewollt oder unbefugt belastet wird. Dadurch läßt sich verhindern, daß die Sperre unter ungünstigen Bedingungen nicht in ihre Sperrstellung gelangt, weil auf den Riegel wirkende Belastungen sich nicht bis auf die Sperre fortsetzen, obwohl die Sperre ihrerseits den Riegel beaufschlagt. Dieser scheinbare Widerspruch wird durch die erfindungsgemäße zusätzliche Bewegungsmöglichkeit des Riegels in eine Blockierstellung beseitigt.Overall, especially when combining one or more of the features and measures described above, there is a locking device in which a low auxiliary force is sufficient to open or close the lock for the bolt, even if the bolt itself is loaded unintentionally or without authorization. This can prevent the lock from not reaching its locking position under unfavorable conditions, because loads acting on the bolt do not continue to the lock, although the lock in turn acts on the bolt. This apparent contradiction is eliminated by the additional movement possibility of the bolt into a blocking position according to the invention.

Nachstehend ist die Erfindung mit ihren ihr als wesentlich zugehörenden Einzelheiten, anhand der Zeichnung in einem Ausführungsbeispiel noch näher beschrieben. Es zeigt in teilweise schematisierter Darstellung :

  • Fig. 1 eine beispielsweise an einem Zeitschloß vorgesehene Verriegelungsvorrichtung in Grundstellung, in welcher der Riegel sich in Schließstellung befindet, nicht belastet ist und die Kniehebelsperre gestreckt ist,
  • Fig. 2 eine der Fig. 1 entsprechende Ansicht der Verriegelungsvorrichtung bei geöffnetem d. h. seitlich verschwenktem Riegel und ausgeknicktem Kniehebel sowie
  • Fig. 3 eine der Fig. 1 entsprechende Darstellung, bei welcher auf den geschlossenen Riegel bei gestreckter, d. h. wirksamer Kniehebelsperre eine Belastung eigentlich zum Öffnen des Riegels ausgeübt wird, der der Riegel in seine Blockierstellung ausweist.
The invention is described in more detail below with its details that are essential to it, with reference to the drawing in an exemplary embodiment. It shows in a partially schematic representation:
  • 1 is a locking device provided, for example, on a time lock in the basic position, in which the bolt is in the closed position, is not loaded and the toggle lock is extended,
  • Fig. 2 is a view corresponding to FIG. 1 of the locking device when the latch is open, ie laterally pivoted, and the knee lever is bent out
  • Fig. 3 is a representation corresponding to FIG. 1, in which a load is actually exerted on the closed bolt when the toggle lever lock is extended, ie effective, to open the bolt which the bolt identifies in its blocking position.

Eine im ganzen mit 1 bezeichnete Verriegelungsvorrichtung ist im Gehäuse 2 beispielsweise eines Zeitschlosses oder auch eines anderen Schloßmechanismus untergebracht. Sie weist einen Riegel 3 und eine insgesamt mit 4 bezeichnete, im folgenden noch näher zu erläuternde Sperre für diesen Riegel 3 auf, die mittels einer Hilfskraft, im Ausführungsbeispiel mittels eines in zwei Richtungen wirkenden Elektromagneten 5 öffen- und schließbar ist. In geschlossener Position kann die Sperre 4 also das Öffnen des Riegels 3 verhindern, während sie in ihrer Öffnungsposition, die anhand der Fig. 2 noch näher beschrieben wird, das Öffnen des Riegels 3 zuläßt.A locking device designated as a whole by 1 is accommodated in the housing 2, for example of a time lock or another lock mechanism. It has a latch 3 and a lock for this latch 3, which is denoted overall by 4 and will be explained in more detail below, and which can be opened and closed by means of an auxiliary force, in the exemplary embodiment using an electromagnet 5 acting in two directions. In the closed position, the lock 4 can thus prevent the bolt 3 from being opened, while in its open position, which is described in more detail with reference to FIG. 2, it permits the bolt 3 to be opened.

Beim Vergleich der Fig. 2 einerseits und der Fig. 3 andererseits einmal miteinander und vor allem mit Fig. 1 erkennt man, daß der Riegel 3 eine zwei unterschiedliche Riegelbewegungen zulassende Lagerung 6 aufweist, wobei die eine Riegelbewegung gemäß Fig. 2 bei geöffneter Sperre 4 zu einer Offenstellung des Riegels 3 und die andere Riegelbewegung gemäß Fig. 3 bei geschlossener Sperre 4 und bei - gegenüber der für die Öffnungsbewegung erforderlichen Kraft - größeren Belastung oder Kraft auf den Riegel 3 in eine Blockierstellung des Riegels führt.When comparing FIG. 2 on the one hand and FIG. 3 on the other hand once and especially with FIG. 1, one can see that the bolt 3 has a bearing 6 which allows two different bolt movements, the one bolt movement according to FIG. 2 with the lock 4 open leads to an open position of the bolt 3 and the other bolt movement according to FIG. 3 with the lock 4 closed and - in relation to the force required for the opening movement - greater load or force on the bolt 3 in a blocking position of the bolt.

Dabei erkennt man eine Abstützung 7 für den Riegel 3 in seiner Blockierstellung, weiche bei einem ungewollten oder unbefugten Öffnungsversuch am Riegel 3 auftretende Kräfte aufnimmt, so daß diese Kräfte von der Sperre 4 abgehalten werden. Der Riegel 3 ist dabei gemäß Fig. 3 verschiebbar und gemäß Fig. 2 verschwenkbar. Im Ausführungsbeispiel ist dabei vorgesehen, daß der Riegel 3 in verschwenkter Position in Offenstellung und gemäß Fig. 3 in verschobener Position in Blockierstellung ist und dann in dieser Blockierstellung die Abstützung 7 beaufschlagt.One can see a support 7 for the bolt 3 in its blocking position, which absorbs forces occurring on the bolt 3 in the event of an unwanted or unauthorized attempt to open, so that these forces are prevented from the lock 4. The latch 3 is displaceable according to FIG. 3 and pivotable according to FIG. 2. In the exemplary embodiment it is provided that the bolt 3 is in the pivoted position in the open position and in FIG. 3 in the shifted position in the blocking position and then acts on the support 7 in this blocking position.

Es ist also möglich, bei normaler Betätigung den Riegel 3 in seine Offenstellung zu verschwenken, sowie die Sperre 4 mit Hilfe des Elektromagneten 5 gelöst ist. Ist die Sperre 4 nicht gelöst und werden dennoch Kräfte auf den Riegel 3 ausgeübt, um ihn in seine Öffnungsposition zu verschwenken, wobei diese Kräfte dann die normalen Öffnungskräfte übersteigen, wird der Riegel gemäß Fig. 3 verschoben, da die Verschwenkung durch die Sperre 4 verhindert ist. Er gelangt dann in eine gegenüber seiner Grundstellung etwas versetzte Position, in der der Schwenkbewegung dann nicht mehr die Sperre, sondern die Abstützung 7 entgegenwirkt, so daß diese Kräfte nicht auf die Sperre 4 einwirken. Die Sperre 4 wird dadurch gewissermaßen von solchen auf den geschlossenen Riegel ausgeübten Kräften freigehalten, so daß die Kraft für die Betätigung der Sperre 4 unbeeinflußt bleibt. Es ist also auch in der Blockierstellung der Fig. 3, in der der Riegel zusätzlichen Kräften ausgesetzt ist, mit der gleichen geringen Hilfskraft des Elektromagneten 5 möglich, die Sperre analog Fig. 2 zu lösen, was verhindert wäre, wenn die zusätzliche Belastung des geschlossenen Riegels 3 unmittelbar auf die Sperre 4 wirken würde.It is therefore possible to pivot the latch 3 into its open position during normal actuation, and the lock 4 is released with the aid of the electromagnet 5. If the lock 4 is not released and forces are nevertheless exerted on the bolt 3 in order to pivot it into its opening position, these forces then exceeding the normal opening forces, the bolt is shifted according to FIG. 3, since the pivoting is prevented by the lock 4 is. He then arrives in a position slightly offset from his basic position, in which the pivoting movement then no longer counteracts the lock, but the support 7, so that these forces do not act on the lock 4. The lock 4 is thereby kept to a certain extent free from such forces exerted on the closed bolt, so that the force for actuating the lock 4 remains unaffected. It is also possible in the blocking position of FIG. 3, in which the bolt is subjected to additional forces, with the same low auxiliary force of the electromagnet 5 to release the lock analogously to FIG. 2, which would be prevented if the additional load on the closed one Bar 3 would act directly on the lock 4.

Vor allem anhand der Fig. 2 wird deutlich, daß die Sperre 4 im Schwenkweg des Riegels 3 im Bereich eines durch die Schwenkung dieses Riegels 3 bewegbaren Teiles angeordnet ist und seitlich dieses Teiles die Abstützung 7 des Riegels 3 für seine Blockierstellung vorgesehen ist. Im Ausführungsbeispiel ist dabei im Schwenkweg des Riegels 3 als bewegbares Teil eine Kulisse 8 od. dgl. Schieber vorgesehen, die die Schwenkbewegung des Riegels 3 in seine Offenstellung in eine lineare Bewegung gegen die Sperre 4 umwandelt. Dies wird beim Vergleich der Position der Kulisse 8 in Fig. 1 und 2 deutlich. Die Kulisse 8 wird von einer Riegelkante 9 beim Verschwenken des Riegels 3 innerhalb ihrer Führung 10 nach oben verschoben und in noch zu beschreibender Weise bei Rückschwenkung des Riegels 3 in seine Sperrstellung gemäß Fig. 1 auch wieder zurückverstellt.2 that the lock 4 is arranged in the pivot path of the bolt 3 in the region of a part which can be moved by the pivoting of this bolt 3 and that the part 7 is provided with the support 7 of the bolt 3 for its blocking position. In the exemplary embodiment, a link 8 or the like is provided in the pivoting path of the bolt 3 as a movable part, which converts the pivoting movement of the bolt 3 into its open position into a linear movement against the lock 4. This becomes clear when comparing the position of the backdrop 8 in FIGS. 1 and 2. The setting 8 is displaced upwards by a locking edge 9 when the locking bar 3 is pivoted within its guide 10 and, in a manner to be described, is also adjusted back when the locking bar 3 is pivoted back into its locking position according to FIG. 1.

Die Sperre 4 ist im Ausführungsbeispiel als Kniehebel ausgebildet, der beim Lösen der Sperre 4 gemäß Fig. 2 einknickt und in Schließstellung gemäß Fig. 1 und 3 gestreckt ist. Dies stellt eine konstruktiv einfache und wirkungsvolle Sperre dar, die auf engem Raum wirksam werden kann, weil sie praktisch in sich selbst ihre Länge ändern kann.The lock 4 is in the embodiment as Knee lever formed, which bends when the lock 4 is released according to FIG. 2 and is stretched in the closed position according to FIGS. 1 and 3. This is a structurally simple and effective barrier that can be effective in a small space because it can practically change its length in itself.

Das dem Knicklager 11 des Kniehebels der Sperre 4 abgewandte Lager 12 des einen Armes 13 des Kniehebels ist dabei im Ausführungsbeispiel an der verschiebbaren Kulisse 8 angeordnet, so daß deren Verschiebung bei gelöster Sperre 4 auch zu der entsprechenden Verschiebung des Lagers 12 und somit zum Einknicken des Kniehebels führt.The angled bearing 11 of the toggle lever of the lock 4 bearing 12 of the arm 13 of the toggle lever is arranged in the exemplary embodiment on the movable link 8, so that its displacement when the lock 4 is released also to the corresponding displacement of the bearing 12 and thus to the buckling of the Toggle lever leads.

Insbesondere in Fig. 2 erkennt man ferner, daß an dem Kniehebel ein durch die Hilfskraft schwenkbarer Betätigungshebel 14 angreift, dessen Schwenklager 15 in der Ruhestellung des Kniehebels, also in der Sperrstellung gemäß Fig. 1 oder 3, mit dem Knicklager 11 übereinstimmt und an dessen zweitem Ende 16 der dem Riegel 3 bzw. der Kulisse 8 abgewandte Kniehebelarm 17 der Sperre 4 schwenkbar gelagert ist. Vor allem beim Vergleich zwischen Fig. 1 und 2 erkennt man deutlich, daß der Betätigungshebel 14 in Schließ- oder Sperrposition der Sperre 4 parallel zu dem gestreckten Kniehebel angeordnet ist,. während er gemäß Fig. 2 um sein Lager 15 mit seinem Ende 16 seitlich ausschwenkt, wenn der Kniehebel geknickt ist. Dabei verändert dann das mittlere Knicklager 11 seine Position gegenüber dem Schwenklager 15 des Betätigungshebels und man erkennt deutlich die mögliche Relativbewegung zwischen dem in dieser Darstellung oberen Kniehebelarm 17 und dem Betätigungshebel 14. Dabei dient der Betätigungshebel 14 zum Vorknicken des Kniehebels, so daß der vorgeknickte Kniehebel der Verschwenkung des Riegels 3 in dessen Öffnungsstellung gemäß Fig. 2 nachgeben kann. Wird also der Betätigungshebel 14 durch den Elektromagneten 5 aus seiner in Fig. 1 dargestellten Position um sein Schwenklager 15 verschwenkt, führt dies zu einer in der Zeichnung nicht näher dargestellten Vorknickung als Vorstufe zu der Position des Kniehebels, die in Fig. 2 durch die dann mögliche Verschwenkung des Riegels 3 in seine Offenstellung hergestellt wird.In particular in Fig. 2 it can also be seen that an actuating lever 14 which can be pivoted by the auxiliary force acts on the toggle lever, the pivot bearing 15 of which corresponds to the articulated bearing 11 in the rest position of the toggle lever, that is to say in the locked position according to FIG. 1 or 3, and on the latter second end 16 of the toggle arm 17 of the lock 4 facing away from the bolt 3 or the link 8 is pivotally mounted. Especially when comparing FIGS. 1 and 2, it can be clearly seen that the actuating lever 14 is arranged parallel to the extended toggle lever in the closed or locked position of the lock 4. while it swings out laterally with its end 16 around its bearing 15 when the toggle is bent. The middle pivot bearing 11 then changes its position with respect to the pivot bearing 15 of the actuating lever and one can clearly see the possible relative movement between the upper toggle lever arm 17 and the actuating lever 14 in this illustration. The actuating lever 14 serves to bend the toggle lever forward, so that the pre-bent toggle lever the pivoting of the bolt 3 in the open position according to FIG. 2 can yield. So if the actuating lever 14 is pivoted by the electromagnet 5 from its position shown in FIG. 1 about its pivot bearing 15, this leads to a pre-bend, not shown in the drawing, as a preliminary step to the position of the toggle lever, which is shown in FIG. 2 by the then possible pivoting of the bolt 3 is made in its open position.

Der relativ zu der Sperre 4 schwenkbare Betätigungshebel 14 kann umgekehrt wirder mittels der an ihm angreifenden Hilfskraft also mittels des Elektromagneten 5 oder auch eines an der entgegengesetzten Seite zusätzlich angreifenden, im dargestellten Ausführungsbeispiel allerdings nicht vorgesehenen Elektromagneten in die der Schließstellung entsprechende Position auch bei geknicktem Kniehebel zurückgeschwenkt werden, so daß er schon wieder in seine Position gebracht werden kann, aus der er nach einer Rückverschwenkung des Riegels in dessen Schließposition und der damit verbundenen Rückstellung der Sperre 4 in ihre Sperrposition für seine Funktion bereit sein.The actuating lever 14, which can be pivoted relative to the lock 4, can be reversed by means of the auxiliary force acting on it, that is to say by means of the electromagnet 5 or also an electromagnet additionally acting on the opposite side, but not provided in the exemplary embodiment shown, into the position corresponding to the closed position even when the toggle lever is bent be pivoted back so that it can already be brought back into its position from which it will be ready for its function after pivoting the bolt back into its closed position and the associated resetting of the lock 4 into its locked position.

Das in Fig. 2 dargestellte Ausknicken des Kniehebels durch das Öffnen des Riegels 3 erfolgt gegen eine den Kniehebel in Sperrstellung zurückführende Rückstellkraft, die auf unterschiedliche Weise erzeugt sein kann. Beispielsweise könnte an der Kulisse 8 eine Feder oder wie im Ausführungsbeispiel die Schwerkraft angreifen. Zusätzlich ist zwischen dem Betätigungshebel 14 und dem Kniehebel eine beim Ausknicken gespannte Feder 18 vorgesehen. Dadurch wird sichergestellt, daß beim Zurückführen des Riegels in seine Schließposition gemäß Fig. 1 die Sperre 4 selbsttätig in ihre Sperrstellung kommt. Die Feder 18 an dem Kniehebel ist dabei als Schenkelfeder ausgebildet, die am Betätigungshebel 14 einerseits und mit Abstand dazu nahe dem Knicklager 11 an dem Kniehebelarm 17 andererseits angreift und in geknickter Position des Kniehebels gemäß Fig. 2 gespannt ist. Diese Feder 18 kann auch in Sperrstellung der Sperre 4 bei gestrecktem Kniehebel gemäß Fig. 1 und 3 eine gewisse Haltekraft auf die Sperre 4 ausüben. Demgemäß ist es zweckmäßig, daß der Kniehebel in gestreckter Position entgegen der Ausknickrichtung einen vorzugsweise einstellbaren Anschlag 19 aufweist, der als verstellbare und mit einer Mutter 20 sicherbare Schraube ausgebildet ist.The buckling of the toggle lever shown in FIG. 2 by opening the latch 3 takes place against a restoring force which returns the toggle lever into the locked position and which can be generated in different ways. For example, a spring or, as in the exemplary embodiment, gravity could act on the backdrop 8. In addition, between the actuating lever 14 and the toggle lever, a spring 18 tensioned when it is bent out is provided. This ensures that when the bolt is returned to its closed position according to FIG. 1, the lock 4 automatically comes into its locked position. The spring 18 on the toggle lever is designed as a leg spring which, on the one hand, engages the actuating lever 14 and at a distance from it, close to the articulated bearing 11 on the toggle lever arm 17, and is tensioned in the bent position of the toggle lever according to FIG. 2. This spring 18 can also exert a certain holding force on the lock 4 in the locked position of the lock 4 with the toggle lever extended according to FIGS. 1 and 3. Accordingly, it is expedient that the toggle lever has a preferably adjustable stop 19 in the extended position against the buckling direction, which stop is designed as an adjustable screw which can be secured with a nut 20.

Zwar könnte die Verriegelungsvorrichtung 1 eine beliebige Orientierung des Riegels 3 und der Sperre 4 vorsehen, jedoch zeigt das Ausführungsbeispiel eine besonders vorteilhafte Lösung, bei welcher die Längserstreckung der Kniehebelsperre 4 vertikal angeordnet und die Kulisse 8 oberhalb des schwenkbaren Riegels 3 auf- und abbewegbar geführt sind, so daß die Schwerkraft zum Strecken des Kniehebels dient oder dazu beiträgt.Although the locking device 1 could provide any orientation of the bolt 3 and the lock 4, the exemplary embodiment shows a particularly advantageous solution in which the longitudinal extension of the toggle lever lock 4 is arranged vertically and the link 8 above the pivotable bolt 3 can be moved up and down , so that gravity serves to extend the knee lever or to contribute to it.

Für die Seitwärtsbewegung des Riegels 3 in seine Blockierstellung bei Belastung des Riegels 3 bei geschlossener Sperre 4 ist an dem Riegel 3 ein Langloch 21 vorgesehen, in welches ein auch als Schwenklager dienender Lagerstift 22 eingreift. Der Lagerstift 22 bildet im Langloch 21 gleichzeitig den Anschlag für eine Rückstellkraft entgegen der Verschiebebewegung des Riegels 3, im Ausführungsbeispiel eine Feder 23, was man besonders in Fig. 3 erkennt, wo der Riegel 3 mit seinem Langloch 21 relativ zu dem Lagerstift 22 in Blockierstellung verschoben ist und dadurch die Feder 23 zusammengedrückt wurde. Dabei hat die Feder 23 an ihrem dem Lagerstift 22 zugewandten Ende ein den Lagerstift beaufschlagendes Lagerteil, nämlich eine Lagerschale 24. Somit ergibt sich eine gute Abstützung für die Feder 23, ohne aber die Schwenkbarkeit des Riegels 3 um den Lagerstift 22 zu beeinträchtigen. Somit ergibt sich die schon vorstehend erwähnte Lagerung 6 für zwei unterschiedliche Bewegungen durch das Zusammenwirken vor allem des Lagerstiftes 22, des Langloches 21 und der Feder 23 mit den Lagerschalen 24.For the sideways movement of the bolt 3 in its blocking position when the bolt 3 is loaded with the lock 4 closed, an elongated hole 21 is provided in the bolt 3, into which a bearing pin 22 which also serves as a pivot bearing engages. The bearing pin 22 forms in the slot 21 at the same time the stop for a restoring force against the displacement movement of the bolt 3, in the exemplary embodiment a spring 23, which can be seen particularly in FIG. 3, where the bolt 3 with its slot 21 relative to the bearing pin 22 in the blocking position is shifted and thereby the spring 23 has been compressed. The spring 23 has at its end facing the bearing pin 22 a bearing part which acts on the bearing pin, namely a bearing shell 24. This results in good support for the spring 23 without, however, impairing the pivotability of the bolt 3 around the bearing pin 22. This results in the above-mentioned bearing 6 for two different movements due to the interaction, in particular, of the bearing pin 22, the elongated hole 21 and the spring 23 with the bearing shells 24.

Im Ausführungsbeispiel ist nämlich die Verriegelungsvorrichtung 1 vor allem zur Verwendung an einem Zeitschloß dargestellt, bei welchem der Riegel 3 in Sperrstellung gemäß Fig.,1 und 3 den Eintritt einer Sperrstange 25 in einen entsprechenden Eintrittskanal 26 verhindert bzw. teilweise verhindert. Der Stift 22 ist dabei im Langloch 21 des Riegels 3 in Ausgangsstellung mittig angeordnet und beidseitig gegen Druckfedern 23 und Lagerschalen 24 abgestützt. Der Riegel 3 ist in diesem Falle aus einer mittleren Sperrstellung nach beiden Seiten in Offenstellungen schwenkbar oder beidseitig in Blockierstellungen verschiebbar und hat beidseitig der mittleren, quer zur Riegelbewegung verschiebbaren Kulisse 8 Abstützungen 7 für die Blockierstellungen. Da beide Verschwenkbewegungen des Riegels 3 jeweils eine Kante 9 mit der Kulisse 8 in entsprechende Wirkverbindung bringen, genügt aber eine einzige Sperre 4 mit der schon früher beschriebenen Funktionsweise, so daß eine derartig ausgebildete Verriegelungsvorrichtung wahlweise für links oder rechts angeschlagene Tresortüren od. dgl. verwendet werden kann, bei denen die Sperrstange 25 entweder von der einen oder der anderen Seite in das Gehäuse 2 eintreten kann. Entsprechend universell ist eine derart ausgestaltete beidseitig beaufschlagbare Verriegelungsvorrichtung einsetzbar.In the exemplary embodiment, the locking device 1 is shown above all for use at a time lock, in which the bolt 3 in the locked position according to FIGS. 1 and 3 prevents or partially prevents the entry of a locking rod 25 into a corresponding entry channel 26. The pin 22 is in the slot 21 of the bolt 3 in the starting position arranged in the center and supported on both sides against compression springs 23 and bearing shells 24. In this case, the bolt 3 can be pivoted from both sides into an open position from a central locking position or can be moved into blocking positions on both sides and has 8 supports 7 for the blocking positions on both sides of the central link that can be moved transversely to the bolt movement. Since both pivoting movements of the bolt 3 each bring an edge 9 with the link 8 into a corresponding operative connection, a single lock 4 with the function already described is sufficient, so that a locking device of this type can be used for left or right hinged safe doors or the like can be in which the locking rod 25 can enter the housing 2 either from one or the other side. A locking device configured in this way, which can be acted on from both sides, can be used correspondingly universally.

An dem der Kulisse 8 abgewandten Ende des Riegels 3 erkennt man mit geringem Abstand zu diesem Riegelende eine kreisbogenförmige Begrenzung 27, gegen welche das freie Ende des schwenkbaren Riegels 3 in Blockierstellung der Sperre 4 bei der Verschiebung des Riegels 3 gemäß Fig. 3 anläuft und sich zusätzlich abstützt, so daß die ungewollten oder unbefugten seitlichen Belastungen des Riegels 3 sowohl auf die Abstützung 7 als auch diese Begrenzung 27 geleitet werden können. Bei der Schwenkbewegung des Riegels 3 bleibt hingegen zwischen dieser Begrenzung 27 und dem Riegel 3 ein Spalt 28 frei. Je nach Größe dieses Spaltes und je nach Balligkeit des Riegels 3 an seinem freien Ende wird dabei die Abstützung gegen die Begrenzung 27 bei seitlicher Verschiebung des Riegels 3 früher oder später eintreten.At the end of the bar 3 facing away from the backdrop 8, a circular arc-shaped boundary 27 can be seen at a short distance from this bar end, against which the free end of the pivotable bar 3 runs in the blocking position of the lock 4 when the bar 3 is moved according to FIG additionally supports, so that the unwanted or unauthorized lateral loads on the bolt 3 can be directed both to the support 7 and this limit 27. In contrast, during the pivoting movement of the bolt 3, a gap 28 remains free between this limitation 27 and the bolt 3. Depending on the size of this gap and depending on the crowning of the bolt 3 at its free end, the support against the boundary 27 will occur sooner or later when the bolt 3 is laterally displaced.

An dem freien verschwenkbaren Ende des Riegels 3 ist eine insbesondere schräge Ausnehmung 28 - im Ausführungsbeispiel mit der beidseitigen Verschwenkbarkeit des Riegels ineinander übergehende Ausnehmungen 28 - vorgesehen, welche Ausnehmungen 28 bei verschwenkter Position des Riegels 3 in seine Offenstellung gemäß Fig. 2 in Fortsetzung des Eintrittskanales 26 für die Sperrstange 25 einer Tresortüre od. dgl. liegt. Man erkennt deutlich in Fig. 2, wie die Sperrstange 25 entlang der oberen Begrenzung der Ausnehmung 28 an dem schräg stehenden Riegel durch die Ausnehmung 28 hindurch bis in den gegenüberliegenden Teil des Eintrittskanales 26 verlaufen kann.At the free pivotable end of the latch 3, a particularly oblique recess 28 - in the exemplary embodiment with the bilateral pivotability of the bolt merging recesses 28 - is provided, which recesses 28 with the pivoted position of the bolt 3 in its open position according to FIG. 2 in continuation of the entry channel 26 for the locking rod 25 of a safe door or the like. It can be clearly seen in FIG. 2 how the locking rod 25 can run along the upper boundary of the recess 28 on the obliquely locking bolt through the recess 28 as far as into the opposite part of the inlet channel 26.

Vor allem bei Verwendung der vorbeschriebenen Verriegelungsvorrichtung 1 in einem Zeitschloß kann zur Betätigung der Sperre 4 mittels eines die Hilfskraft erzeugenden Elektromagneten 5 ein elektronisches Uhrwerk vorgesehen sein, das je nach eingestellter Zeit den Elektromagneten 5 im Sinne einer Öffnung der Sperre 4 betätigen kann. Dabei kann dafür Sorge getragen sein, daß der Elektromagnet 5 dann den Betätigungshebel 14 schon wieder in Schließstellung bewegt, selbst wenn der Riegel 3 noch offen ist, wenn das Zeitschloß für eine neue Sperrzeit eingestellt wird.Especially when using the above-described locking device 1 in a time lock, an electronic clockwork can be provided for actuating the lock 4 by means of an electromagnet 5 which generates the auxiliary force and which, depending on the set time, can actuate the electromagnet 5 in the sense of opening the lock 4. It can be ensured that the electromagnet 5 then moves the actuating lever 14 again into the closed position, even if the bolt 3 is still open when the time lock is set for a new blocking time.
