Description

Die Erfindung bezieht sich auf eine Scharf-/Unscharf-Schaltvorrichtung für eine Einbruchmeldeanlage mit einer elektromechanisch betätigbaren Sperre und einem Riegelkontakt hinter einem Schließblech einer Türzarge und mit einem Riegel eines Riegelschlosses in einer zugehörigen Türe.The invention relates to an arming / disarming switching device for an intruder alarm system with an electromechanically actuated lock and a bolt contact behind a striking plate of a door frame and with a bolt of a bolt lock in an associated door.

Eine derartige Schaltvorrichtung ist beispielsweise in der Europäischen Patentanmeldung EP-A-0 222 194 beschrieben und wird im allgemeinen als Blockschloß bezeichnet. Bei der Scharf-/Unscharfschaltung einer Einbruchmeldeanlage wird für die mechanische Blockierung eines Riegelschlosses eine Sperr-Vorrichtung benötigt, damit bei einer unscharf geschalteten Anlage das Abschließen, d.h. das Verriegeln der Tür, nicht möglich ist. Es darf jedoch bei einer scharfgeschalteten Einbruchmeldeanlage das Riegelschloß nicht aufgeschlossen werden können, um keinen ungewollten Alarm auszulösen. Eine solche elektromechanisch gesteuerte Sperrvorrichtung soll bei Verwendung eines handelsüblichen Riegelschlosses in der Türzarge eingebaut werden können. Dabei können sehr große und veränderbare Eingriffstoleranzen zwischen dem Schließblech und dem Schloßriegel auftreten. In Einbruchmeldeanlagen ist für derartige Blockschlösser auch bei robusten Betriebsverhältnissen eine hohe Funktionssicherheit erforderlich.Such a switching device is described for example in European patent application EP-A-0 222 194 and is generally referred to as a block lock. When arming / disarming an intrusion alarm system, a locking device is required for the mechanical blocking of a deadbolt lock, so that the locking, i.e. locking the door is not possible. However, it must not be possible to unlock the bolt lock in an armed intrusion alarm system in order not to trigger an unwanted alarm. Such an electromechanically controlled locking device should be able to be installed in the door frame when using a commercially available bolt lock. Very large and changeable engagement tolerances can occur between the striking plate and the lock bolt. In burglar alarm systems, a high level of functional reliability is required for block locks of this type, even under robust operating conditions.

Bei der bekannten Schaltvorrichtung wurde als Sperre ein Hubmagnet vorgesehen, der im geöffneten Zustand (Ruheposition) einen Dauerstrom zieht und in der Sperrposition bei geöffneter Tür durch Zurückdrücken des Stöpsels leicht manipulierbar ist.In the known switching device, a lifting magnet was provided as a lock, which draws a continuous current in the open state (rest position) and is easy to manipulate in the locked position when the door is open by pushing back the plug.

Außerdem ist der Platzbedarf bei einem erforderlichen Hub von beispielsweise mehr als 10 mm für den Einbau in einem Schließblech verhältnismäßig groß.In addition, the space required for a required stroke of more than 10 mm for installation in a striking plate is relatively large.

Aufgabe der Erfindung ist es, eine Scharf-/Unscharf-Schaltvorrichtung der eingangs genannten Art mit einer Sperre zum mechanischen Blockieren eines vorhandenen Sperrschlosses derart weiterzubilden, daß ein geringer Platzbedarf und eine hohe Zuverlässigkeit erzielt werden kann.The object of the invention is to develop an arming / disarming switching device of the type mentioned at the outset with a lock for mechanically blocking an existing locking lock such that a small space requirement and high reliability can be achieved.

Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved with the features of claim 1.

Die Schaltvorrichtung weist eine als Schieber ausgebildete Sperrvorrichtung auf, die mittels eines Antriebsmechanismus Von einem Elektromotor aus einer Ruhestellung in eine Verriegelungsstellung oder eine Sperrstellung gebracht werden kann. Ist die Einbruchmeldeanlage in Betrieb aber unscharf geschaltet, so nimmt der Schieber die Sperrposition ein, so daß ein Abschließen der Türe, d.h. das Einfahren des Riegels in das Schließblech, verhindert wird. Ist die Anlage ordnungsgemäß scharfgeschaltet, so nimmt der Schieber die Verriegelungsposition ein und verhindert damit das Aufschließen des Riegels, weil der Schieber einen Ansatz und der Riegel eine Anformung aufweisen, die in der Verriegelungsposition miteinander in Eingriff stehen. Der Schieber wird in der Sperrposition mit einem Anschlag begrenzt. Das Ausfahren des Schiebers in die Verriegelungsposition wird vom eingefahrenen Riegel begrenzt. Dies hat den Vorteil, daß Toleranzen, die zwischen Türzarge und Riegel des Riegelschlosses und der Riegelöffnung im Schließblech der Zarge bestehen, mit dem Hin- und Herfahren des Schiebers ausgeglichen werden können.The switching device has a blocking device designed as a slide, which can be brought from a rest position into a locking position or a blocking position by an electric motor by means of a drive mechanism. If the burglar alarm system is in operation but disarmed, the slide assumes the locked position so that the door can be locked, i.e. retraction of the bolt into the striking plate is prevented. If the system is properly armed, the slider assumes the locking position and thus prevents the bolt from being unlocked because the slider has a projection and the bolt has a projection which are in engagement with one another in the locking position. The slide is limited in the locked position with a stop. Extending the slide into the locking position is limited by the retracted bolt. This has the advantage that tolerances that exist between the door frame and bolt of the bolt lock and the bolt opening in the striking plate of the frame can be compensated for by moving the slide back and forth.

Zweckmäßigerweise ist der Elektromotor von einem Gleichstrommotor gebildet, der elektrisch umpolbar ist und damit ein Verschieben des Schiebers in beide Richtungen ermöglicht. Hierzu ist in vorteilhafter Weise der Antriebsmechanismus von einem Schraubentrieb gebildet.The electric motor is expediently formed by a direct current motor which can be electrically reversed and thus a Allows moving the slider in both directions. For this purpose, the drive mechanism is advantageously formed by a screw drive.

Eine derartig ausgestaltete Scharf-/Unscharf-Schaltvorrichtung erlaubt einen Einbau unmittelbar im Schließblech, z.B. unterhalb der Riegelöffnung.Such an arming / disarming switching device allows installation directly in the striking plate, e.g. below the bolt opening.

Ferner ist es zweckmäßig, bei Erreichen einer der vorgesehenen Positionen des Schiebers die Stromaufnahme abzuschalten oder zumindest durch geeignete Schaltmaßnahmen zu begrenzen.Furthermore, it is expedient to switch off the current consumption when one of the intended positions of the slide is reached, or at least to limit it by means of suitable switching measures.

Die Erfindung wird an einem Ausführungsbeispiel anhand der Zeichnung erläutert. Dabei zeigen
Fig. 1 bis 3 das Ausführungsbeispiel in verschiedenen Ansichten.The invention is explained using an exemplary embodiment with reference to the drawing. Show
1 to 3 the embodiment in different views.

Die erfindungsgemäße Scharf-/Unscharf-Schaltvorrichtung weist eine Sperrvorrichtung mit einem Stellglied auf. Als Stellglied wird ein elektrisch umpolbarer Gleichstrommotor 1 verwendet, der über den Schraubentrieb 2 den Schieber 3 in beide Richtungen bewegen kann. Ist die Einbruchmeldeanlage nicht in Betrieb, so ist der Schieber 3 in die Ruheposition zurückgefahren. Im eingeschalteten, jedoch unscharf geschalteten Zustand der Einbruchmeldeanlage ist der Schieber 3 bis zum Anschlag 4 ausgefahren und verdeckt somit einen Teil der Riegelöffnung 5a am Schließblech 5, so daß der Riegel 6 des Riegelschlosses der Türe nicht geschlossen werden kann. Ist die Anlage im scharfgeschalteten Zustand, so wird der Motor 1 kurzzeitig von der Meldezentrale aus angesteuert und der Schieber 3 gibt die Riegelöffnung 5a für das Verschließen frei. Wird nun beim Verschließen der letzten Türe der Riegel 6 in das Schließblech 5 eingefahren, so wird der Riegelkontakt 7 betätigt, wodurch von der Zentrale gesteuert der Motor 1 den Schieber 3 wieder ausfährt, bis der Riegel 6 den Hub begrenzt, d.h. der Schieberansatz 3a an der Unterseite des Riegels anstößt (Verriegelungsposition VP). Das hat den Vorteil, daß unabhängig von der momentanen Einbauanlage des Riegels der eingefahrene Riegel 6 zuverlässig und sicher gesperrt ist, weil der Schieberansatz 3a mit der Anformung 8, die bei-spielsweise von eine Spannstift gebildet sein kann, ein Entriegeln verhindert. Ist der Schieber 3 mit seinem Anschlag 3a am Riegel 6 angeschlagen, so ist der Motor 1 blockiert, der zweckmäßigerweise über entsprechende Einrichtungen abgeschaltet wird oder zumindest in seiner Stromaufnahme erheblich begrenzt wird.The arming / disarming switching device according to the invention has a locking device with an actuator. An electrically reversible DC motor 1 is used as the actuator, which can move the slide 3 in both directions via the screw drive 2. If the intrusion alarm system is not in operation, the slide 3 has moved back to the rest position. When the burglar alarm system is switched on but not activated, the slide 3 is extended as far as the stop 4 and thus covers part of the bolt opening 5a on the striking plate 5, so that the bolt 6 of the bolt lock of the door cannot be closed. If the system is in the armed state, the motor 1 is briefly activated from the signaling center and the slide 3 releases the bolt opening 5a for locking. If the bolt 6 is now retracted into the striking plate 5 when the last door is closed, the bolt contact 7 is actuated, as a result of which the motor 1 controls the slide 3 again until the bolt 6 limits the stroke, controlled by the control center. ie the slide extension 3a abuts the underside of the bolt (locking position VP). This has the advantage that regardless of the current installation system of the bolt, the retracted bolt 6 is reliably and securely locked because the slide attachment 3a with the projection 8, which can be formed, for example, by a dowel pin, prevents unlocking. If the slide 3 strikes the bolt 6 with its stop 3a, the motor 1 is blocked, which is expediently switched off by means of appropriate devices or at least considerably limited in its current consumption.

Der am Riegel 6 anliegende Schieber 3 verhindert ein Aufschließen, weil der Spannstift 8 am Riegel ein Entriegeln am Schieberansatz 3a verhindert. Erst nach der Freigabe über einen geistigen Verschluß oder eine ähnliche Einrichtung, d.h. bei einem berechtigten Unscharfschalten, fährt der Schieber 3 in die Ausgangsstellung (Ruheposition RP) zurück. Das Riegelschloß kann dann aufgeschlossen werden. Dabei wird der Riegelkontakt 7 geöffnet und die Einbruchmeldeanlage endgültig unscharf geschaltet. Um ein versehentliches Verriegeln der Tür zu verhindern wird dann der Schieber 3 in die Sperrposition SP bis zum Anschlag 4 ausgefahren, so daß ein Teil der Riegelöffnung 5a verschlossen ist.The slide 3 resting on the bolt 6 prevents unlocking because the spring pin 8 on the bolt prevents unlocking on the slide extension 3a. Only after release via a mental lock or similar device, i.e. in the event of an authorized disarming, the slide 3 moves back to the starting position (rest position RP). The bolt lock can then be unlocked. The bolt contact 7 is opened and the intrusion alarm system is finally disarmed. In order to prevent accidental locking of the door, the slide 3 is then extended into the blocking position SP up to the stop 4, so that part of the bolt opening 5a is closed.
