In mindestens einer Tür befindet sich ein Schließzylinder, über den mittels eines Schlüssels sowohl Steuerschalter als auch jeder Schließvorrichtung zugeordnete Unterdruckelemente beeinflußbar sind, um die zentrale Ver- bzw. Entriegelung hervorzurufen. Jeder Schloßhebel ist mit einer Kurvenbahn versehen, in der ein von dem jeweiligen Unterdruckelement betätigbares Schaltgestänge gleitet. Im unteren Teil der Kurvenbahn stützt sich das Schaltgestänge an einem in der Tür ortsfest angeordneten, bei Betätigung des Verrlegelungs- . knopfs unüberwindbaren Anschlag ab. Bei Betätigung des Schließzylinders wird das Schaltgestänge durch Unterdruckbeaufschlagung selbsttätig aus der entriegelungssperrenden Kurvenbahn befreit (DE-AS-26 47 791A central locking system for doors is also known which has a lock lever with a locking button articulated longitudinally displaceably on the inside of the door. In at least one door there is a locking cylinder, by means of which a key can be used to influence both the control switch and the vacuum elements assigned to each locking device in order to cause the central locking and unlocking. Each lock lever is provided with a cam track in which a shift linkage that can be actuated by the respective vacuum element slides. In the lower part of the cam track, the shift linkage is supported on a stationary arrangement in the door when the locking mechanism is actuated. button insurmountable stop. When the locking cylinder is actuated, the shift linkage is automatically freed from the unlocking cam track by applying negative pressure (DE-AS-26 47 791

Bekannt ist ferner eine Zentralverriegelungsanlage mit mehreren elektromagnetisch betätigbaren Türen von denen zwei durch je ein mit einem abziehbaren Schlüssel betätigbaren Schloß ver-und entriegelbar sind. Die Schlösser sind mit je einem Schalter zum Steuern der Elektromagnete aller Türen gekoppelt. Beim Verriegeln der Tür mittels des Schlosses wird der dieser Tür zugeordnete Elektromagnet von der Stromquelle abgeschaltet, bevor die Elektromagnete der übrigen Türen an Spannung gelegt werden (DE-C-11 30 728).Also known is a central locking system with a plurality of electromagnetically actuated doors, two of which can be locked and unlocked by a lock which can be actuated with a removable key. The locks are each coupled to a switch for controlling the electromagnets of all doors. When the door is locked by means of the lock, the electromagnet assigned to this door is switched off by the power source before the electromagnets of the other doors are energized (DE-C-11 30 728).

Bei einer anderen bekannten Zentralverriegelungsanlage von Seitentüren eines Fahrzeugs ist eine Zentralsteuerung vorgesehen, über die alle Türen verriegelbar sind. Die Vordertüren weisen je ein Schloß auf, das über ein Betätigungsorgan von Hand mittels eines Schlüssels ver- und entriegelbar ist. Im Schloß ist ein Schalter vorhanden, der bei der Verriegelungsbewegung des Betätigungsorgans ein Signal an die Zentralsteuerung abgibt, die auf dieses Signal hin die übrigen Seitentüren verriegelt (DE-A-28 21 901).In another known central locking system for side doors of a vehicle, a central control is provided via which all doors can be locked. The front doors each have a lock, which can be locked and unlocked by hand using an actuator using a key. In the lock there is a switch which, when the actuator is locked, emits a signal to the central control, which locks the other side doors in response to this signal (DE-A-28 21 901).

Schließlich ist eine Zentralverriegelungsanlage für Türen bzw. Hauben, Deckel und/oder Fenster von Fahrzeugen bekannt, die mindestens einen manuell betätigbaren Zentralschalter enthält, der mit einer Zentralsteuereinheit verbunden ist. Über die Zentraisteuereinheit sind mehrere Verriegelungselemente betätigbar, die je einen Geber aufweisen, der einerseits mit dem Schließzylinder oder Verriegelungsknopf des jeweiligen Schlosses der Fahrzeugöffnung mechanisch und andererseits mit Anschlußleitungen an die Zentralsteuereinheit angeschlossen ist (DE-A-29 23 505),Finally, a central locking system for doors or hoods, lids and / or windows of vehicles is known which contains at least one manually operated central switch which is connected to a central control unit. Several locking elements can be actuated via the central control unit, each of which has an encoder which is connected mechanically to the central control unit with the lock cylinder or locking button of the respective lock of the vehicle opening and on the other hand with connecting lines (DE-A-29 23 505),

Der Erfindung liegt die Aufgabe zugrunde, ein System der eingangs beschriebenen Gattung dahingehend weiterzuentwickeln, daß an einem beliebig ausgewählten Schloß eine manuelle Verriegelung oder Entriegelung mit einem Schlüssel dann vorgenommen werden kann, wenn zuvor die anderen Schlösser des Systems, veranlaßt durch die Betätigung des Schlüssels, die mit dem Schlüssel einzustellende Betriebsposition eingenommen haben.The invention has for its object to further develop a system of the type described above in such a way that manual locking or unlocking with a key can be carried out on an arbitrarily selected lock if the other locks of the system, previously caused by the actuation of the key, have taken the operating position to be set with the key.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß für jedes Schloß eine mit einem Schlüssel betätigbare Einrichtung für die Verschiebung des Riegels in die Öffnungs- und Schließstellung vorgesehen ist, daß aus der Drehung des in ein Schloß eingeführten Schlüssels vor der Verschiebung des zugehörigen Riegels ein Steuersignal für die Ansteuerung der Antriebe aller anderen Schlösser zu deren Ver- oder Entriegelung abgeleitet ist und daß aus der Einnahme der Ver- oder Entriegelungsstellung aller anderen Schlösser ein Freigabesignal für das durch den Schlüssel betätigte Schloß abgeleitet ist.The object is achieved in that a lockable device for moving the bolt into the open and closed position is provided for each lock, that a control signal for the rotation of the key inserted into a lock before the displacement of the associated bolt the control of the drives of all other locks for their locking or unlocking is derived and that a release signal for the lock actuated by the key is derived from the taking of the locking or unlocking position of all other locks.

Als Antrieb kann zweckmäßigerweise ein pneumatisches oder hydraulisches Stellglied vorgesehen sein. Bei einer bevorzugten Ausführungsform ist als Antrieb ein Elektromotor vorgesehen, der über ein Zahnrad in einen zahnstangenartigen Abschnitt des Schlosses eingreift.A pneumatic or hydraulic actuator can be expediently provided as the drive. In a preferred embodiment, an electric motor is provided as the drive, which engages via a gearwheel in a rack-like section of the lock.

Eine günstige Ausführungsform besteht darin, daß in den Schlössern jeweils bei der Bewegung des drehbaren Teils des Schließzylinders die Energieversorgung für den Antrieb unterbrechbar ist. Das Schloß wird dabei auf einfache Weise für die mechanische Betätigung des Riegels freigegeben. Vorzugsweise wird durch eine mit dem drehbaren Teil des Schließzylinders verbundene Nase ein Endschalter betätigt, der in der Energieversorgungsleitung des Elektromotors angeordnet ist. Bei Drehung des Schlüssels öffnet der Endschalter den Stromkreis, in dem der Elektromotor liegt.A favorable embodiment is that the energy supply for the drive can be interrupted in the locks each time the rotatable part of the lock cylinder moves. The lock is released in a simple manner for the mechanical actuation of the bolt. A limit switch, which is arranged in the power supply line of the electric motor, is preferably actuated by a nose connected to the rotatable part of the locking cylinder. When the key is turned, the limit switch opens the circuit in which the electric motor is located.

Vorzugsweise sind in den Schlössern Geber vorhanden, mit denen die Schließlage des jeweiligen Riegels feststellbar ist. Aus der Stellung dieser Geber läßt sich auch erkennen, ob der Riegel nicht in seiner Endlage ist. Diese Geber müssen angesprochen haben, bevor das Öffnen oder Schließen eines der Schlösser von Hand zu Ende geführt werden kann.Preferably there are sensors in the locks with which the closed position of the respective bolt can be determined. From the position of these donors can also be seen whether the Bolt is not in its end position. These transmitters must have responded before one of the locks can be opened or closed by hand.

Zweckmäßigerweise werden die Endlagen der Riegel in Öffnungsstellung durch Geber überwacht. Es ist also sowohl die Verriegelungsstellung als auch die Öffnungsstellung der Riegel feststellbar. Wenn sich ein jeweiliger Riegel weder in Öffnungs- noch in Schließstellung befindet, ohne daß eine Betätigung eines oder mehrerer Schlösser stattfindet, kann dies als Störung des Schlosses oder der Endschalter ausgewertet werden.The end positions of the bolts in the open position are expediently monitored by sensors. So both the locking position and the open position of the bolt can be determined. If a respective bolt is neither in the open nor in the closed position without one or more locks being actuated, this can be evaluated as a fault in the lock or the limit switches.

Bei einer bevorzugten Ausführungsform ist im Wege der Nase des drehbaren Teils des Schließzylinders ein Geber vorgesehen, der vor dem Abziehen des Schlüssels betätigt wird. Dieser Schalter dient sowohl beim manuellen Abschließen als auch beim Öffnen des Schlosses zur Meldung. Eine zweckmäßige Ausführungsform besteht darin, daß die Bewegung des Riegels mittels eines Antriebs sperrbar ist, der bei manueller Betätigung eines Schlosses den Riegel nach der Verriegelung oder Entriegelung der anderen Schlösser freigibt. Der Antrieb ist vorzugsweise als Elektromagnet mit Drehanker ausgebildet, wobei unter Spannung die Bewegung des Riegels blockiert wird. Auf diese Weise wird sichergestellt, daß bei Spannungsausfall die Schlösser auch von Hand betätigt werden können. Es ist günstig, wenn alle Geber mit einer zentralen Steuerstelle verbunden sind, die Meldeelemente für die jeweiligen Stellungen der Riegel aufweist. Aus den die Schließstellung aller Riegel anzeigenden Meldungen kann vorteilhafterweise eine Sammelmeldung zur Scharfeinstellung einer Alarmanlage erzeugt werden.In a preferred embodiment, a transmitter is provided in the way of the nose of the rotatable part of the locking cylinder, which is actuated before the key is removed. This switch is used both for manual locking and for opening the lock. An expedient embodiment consists in that the movement of the bolt can be blocked by means of a drive which, when a lock is operated manually, releases the bolt after the other locks have been locked or unlocked. The drive is preferably designed as an electromagnet with a rotating armature, the movement of the bolt being blocked under tension. This ensures that the locks can also be operated by hand in the event of a power failure. It is advantageous if all transmitters are connected to a central control point which has signaling elements for the respective positions of the bolts. From the messages indicating the closed position of all bolts, a collective message for focusing an alarm system can advantageously be generated.

Die Erfindung wird im folgenden an Hand eines in einer Zeichnung dargestellten Ausführungsbeispiels näher erläutert, aus dem sich weitere Merkmale sowie Vorteile ergeben.The invention is explained in more detail below with reference to an embodiment shown in a drawing, from which further features and advantages result.

Wird der Schlüssel im Uhrzeigersinn gedreht, dann greift die Nase 6 in die Einkerbung 5 ein und bewegt den Riegel 4 in seine Öffnungsstellung.When the movable part of the locking cylinder 7 is turned counterclockwise by means of a key, the nose 6 lies against the end 12 of the bolt 4 and pushes it into the closed position. If the key is turned clockwise, the nose 6 engages in the notch 5 and moves the bolt 4 into its open position.

Im Gehäuse 2 ist ferner ein elektromechanischer Antrieb 13 für den Riegel 4 vorgesehen. Der Antrieb 13 besteht aus einem Elektromotor 14, auf dessen Rotorwelle 16 ein Ritzel 15 angeordnet ist, das in eine Zahnstange 17 eingreift, die am Riegel 4 befestigt ist.

The encoder 19 has an angle of rotation of approximately 45 ° relative to the open position of the nose 6. A work contact 20 is arranged in the transmitter 19 and is arranged in the energy supply line of the electric motor 14. A swivel jack 21 is also arranged with one end 22 in the rotational path of the nose 6. The end 22 has an opposite position on the locking cylinder 7 with respect to the flag of the transmitter 19. Via the other end of the pivoting lever 21, a further transmitter 23, designed as a limit switch, can be actuated, which has an operating contact 24.

In Schließstellung des Riegels 4 ist ein zusätzlicher als Endschalter ausgebildeter Geber 25 vorgesehen, der ebenfalls einen Arbeitskontakt 26 enthält. Der Geber ist mit einer Fahne 27 versehen, die in der Schließstellung des Riegels 4 nach unten gedrückt wird.In the closed position of the bolt 4, an additional transmitter 25 designed as a limit switch is provided, which also contains a normally open contact 26. The encoder is provided with a flag 27 which is pressed down in the closed position of the bolt 4.

Ein weiterer Geber 28, bei dem es sich um einen Endschalter handelt, ist in Öffnungsstellung des Riegels 4 über einen Stößel 29 betätigbar. Der Geber 28 hat einen Arbeitskontakt 30.Another transmitter 28, which is a limit switch, can be actuated by a plunger 29 in the open position of the bolt 4. The encoder 28 has a normally open contact 30.

Im Gehäuse 2 sind noch zwei weitere Geber 31, 32 vorhanden, die al9 Endschalter ausgebildet sind. Der Geber 31 liegt mit seiner Fahne 33 an der Schraube 11 an und wird von dieser betätigt. Der Arbeitskontakt 34 des Gebers 31 ist daher geschlossen, wenn die Schraube 11 im Gehäuse 2 befestigt ist. Der Geber 32 liegt mit einer nicht näher dargestellten Fahne am Deckblech des Schlosses 1 an. Daher ist ein Arbeitskontakt 35 des Gebers 32 betätigt, wenn das Deckblech auf dem Schloß 1 aufgeschraubt ist. Die beiden Kontakte 34, 35 sind in Reihe geschaltet.In the housing 2 there are two further sensors 31, 32 which are designed as limit switches. The encoder 31 abuts the screw 11 with its flag 33 and is actuated by the latter. The normally open contact 34 of the encoder 31 is therefore closed when the screw 11 is fastened in the housing 2. The encoder 32 rests on the cover plate of the lock 1 with a flag, not shown in detail. Therefore, a normally open contact 35 of the transmitter 32 is actuated when the cover plate is screwed onto the lock 1. The two contacts 34, 35 are connected in series.

Im Gehäuse 2 ist weiterhin ein Elektromagnet 36 angeordnet, dessen Joch 37 und Kern 38 auf einen Drehanker 39 einwirkt, der einen Hebelarm 40 aufweist, der gegen einen Anschlag 41 der Plattform 18 andrückbar ist. Der Elektromagnet 36 hat eine Wicklung 42.In the housing 2 there is also an electromagnet 36, the yoke 37 and core 38 of which act on a rotating armature 39 which has a lever arm 40 which can be pressed against a stop 41 of the platform 18. The electromagnet 36 has a winding 42.

Der Motor 14, die Arbeitskontakte 20, 24, 26, 30, 34 und 35 und die Wicklung 42 sind über ein Kabel 43 mit einer zentralen Steuereinheit 44 verbunden. Im Ruhezustand des Schlosses 1 haben die Geber im Schloß 1 folgende Stellungen, wobei der Riegel 4 in das Schloß eingefahren ist :

  • Geber 25 : nicht betätigt
  • Geber 28 : über den Riegel 4 und den Stößel 29 betätigt
  • Geber 19 : durch die 90°-Schließnase des Zylinders betätigt
  • Geber 23 : nicht betätigt
  • Geber 31 : durch die Befestigungsschraube des Schließzylinders aktiviert
  • Geber 32: durch Aufschrauben des Deckbleches betätigt
The motor 14, the working contacts 20, 24, 26, 30, 34 and 35 and the winding 42 are connected to a central control unit 44 via a cable 43. When the lock 1 is in the idle state, the sensors in the lock 1 have the following positions, the bolt 4 being moved into the lock:
  • Encoder 25: not activated
  • Encoder 28: actuated via the bolt 4 and the plunger 29
  • Encoder 19: actuated by the cylinder's 90 ° locking lug
  • Encoder 23: not activated
  • Encoder 31: activated by the locking screw of the locking cylinder
  • Encoder 32: actuated by screwing on the cover plate

Dieser Grundzustand trifft auf alle am System befindlichen Schlösser 1 zu.This basic state applies to all locks 1 on the system.

Erfolgt von einer beliebigen Schloßstelle ein Schließwunsch, so wird dieser der Steuerzentrale über den Geber 19 gemeldet. Gleichzeitig wird an diesem Schloß 1 die Zuleitung zum Motor 14 unterbrochen. Die Zentrale prüft nun die restlichen Schlösser 1 auf ihren ordnungsgemäßen Zustand und erwartet gegebenenfalls weitere In. formationen eines übergeordneten Systems. Sind alle Parameter in Ordnung, so werden die Magnetspulen 42, außer am betätigten Schloß, aktiviert und heben hierdurch den Drehanker 39 an. Eine spezielle Ausgabeeinheit legt nun in der richtigen Polarität eine Spannung an die Motore, welche die Riegel 4 über die Ritzel 15 und Zahnstange 17 bis an den äußeren Anschlag fährt. Parallel werden die Arbeitskontakt 30 und 24 zur Rückmeldung ausgenutzt. Geber 28 meldet « Riegel ausgefahren und Geber 23 « Riegel in Türrahmen eingefahren.If a lock request is made from any lock location, this is reported to the control center via the transmitter 19. At the same time, the lead to the motor 14 is interrupted at this lock 1. The control center now checks the remaining locks 1 for their proper condition and expects further In if necessary. formations of a higher-level system. If all parameters are in order, the magnetic coils 42 are activated, except for the actuated lock, and thereby raise the rotating armature 39. A special output unit now applies the correct polarity to the motors, which drives the bolt 4 via the pinion 15 and rack 17 to the outer stop. In parallel, work contacts 30 and 24 are used for feedback. Encoder 28 reports «Bolt extended and Encoder 23« Bolt retracted into the door frame.

Erfaßt die Zentrale 44 eine Störung, so unterbleibt die Spannungszufuhr an Spule 42 des mechanisch betätigten Schlosses 1 und der Riegel 4 wird über den Hebel 40 am Herausschieben gehindert. Ist alles in Ordnung, so wird die Spule 42 aktiviert und der Riegel 4 läßt sich über die Schließnase 6 des Schließzylinders nach außen bewegen. Hier wird ebenfalls das ordnungsgemäße Schalten der Geber 23 und 28 überprüft. Um den Schlüssel abzuziehen, muß der Schließbart mit der Nase 6 in die 90°-Stetiung weitergedreht werden. Hier wird der Kontakt 24 über den Hebel 21 kurz getastet. Die Ruhestellung ist nach Betätigen des Gebers 23 erreicht. Sämtliche am System liegenden Verschlußeinrichtungen sind nun verriegelt und die Information « Türen gesperrt steht zur Weiterverarbeitung zur Verfügung (z. B. Scharfsignal für Alarmanlagen).If the control center 44 detects a fault, the voltage supply to the coil 42 of the mechanically operated lock 1 does not occur and the bolt 4 is prevented from being pushed out by the lever 40. If everything is OK, the coil 42 is activated and the bolt 4 can be moved outwards via the locking lug 6 of the locking cylinder. The correct switching of the transmitters 23 and 28 is also checked here. In order to remove the key, the lock bit with the nose 6 must be turned further into the 90 ° position. Here the contact 24 is briefly keyed via the lever 21. The rest position is reached after actuating the encoder 23. All locking devices on the system are now locked and the information «Doors locked is available for further processing (e.g. arming signal for alarm systems).

Tritt während dem gesperrten Zustand eine nicht sinnvolle Schalterzustandsänderung ein, so wird diese als Sabotagemeldung an eine geeignete Stelle abgesetzt (z. B. Riegel wird gewaltsam zurückgedrückt).If a non-sensible change in the switch status occurs during the locked state, it is sent to a suitable location as a sabotage message (e.g. bolt is pressed back by force).

Erfolgt von einer beliebigen Schlußstelle ein Aufsperrwunsch, so wird dies durch Verlassen der Schalterstellungen der Geber 19 und 23 angezeigt. Liegt von Seiten des übergeordneten Systems keine Aufschließsperre (Kriterium) vor, so werden bei allen nicht betätigten Schlössern die Riegel mit Hilfe der Spulenfreigabe und dem Motor 14 bewegt. Gleichzeitig erscheint mit der Spulenfreigabe am manuell betätigten Schloß eine Meldung, die an eine geeignete, übergeordnete Stelle abgesetzt wird (z. B. Unscharfsignal für eine Alarmanlage). Das Abziehen des Schlüssels ist wiederum nur in der 90°-Stellung erlaubt. Alle am System hängenden Schlösser sind nun entriegelt.If an unlock request is made from any end point, this is indicated by leaving the switch positions of the transmitters 19 and 23. If there is no unlocking lock (criterion) on the part of the higher-level system, the bolts are moved with the aid of the coil release and the motor 14 in all locks which are not actuated. At the same time, when the spool is released, a message appears on the manually operated lock, which is sent to a suitable, higher-level location (e.g. unset signal for an alarm system). Removing the key is only permitted in the 90 ° position. All locks attached to the system are now unlocked.

Ein Sabotageversuch, z. B. durch Herausdrehen der Zylinderschraube, wird durch den Geber 31 und der fehlende Gehäusedeckel durch den Geber 32 erkannt. Für höhere Risiken ist eine Aufbohrsicherung vorgesehen, die über einen Piezokristall auf dem Gehäuse die Bohrfrequenzen auswerten und sie als Sabotagemeldung an das übergeordnete System weiterleitet.An attempt at sabotage, e.g. B. by unscrewing the cheese head screw, is recognized by the encoder 31 and the missing housing cover by the encoder 32. For higher risks, a drill protection is provided, which evaluates the drilling frequencies via a piezo crystal on the housing and forwards them to the higher-level system as a sabotage message.
