Description

Die Erfindung betrifft ein Zündschloß für ein Kraftfahrzeug, mit einem Schloßzylinder, der durch einen Schlüssel betätigbar ist und eine Aussparung aufweist, die sich in Ruhestellung des Schlosses in Flucht mit einem Tauchkern eines Elektromagneten befindet.The invention relates to an ignition lock for a motor vehicle, with a lock cylinder which can be actuated by a key and has a recess which is in alignment with the plunger of an electromagnet when the lock is in the rest position.

Eine der häufigsten Ursachen des Diebstahls von Kraftfahrzeugen ist die verhältnismäßige Leichtigkeit, mit der ein Zündschlüssel in Besitz gebracht oder nachgefertigt werden kann. Es kommt nur allzu oft vor, daß der Fahrer eines. Fahrzeugs den Zündschlüssel im Zündschloß stecken läßt. Andererseits ist es für einen Dieb verhältnismäßig leicht, mit Hilfe eines Abdrucks oder durch einfaches Ablesen der auf dem Schlüssel eingeprägten Codenummer eine Nachfertigung eines Schlüssels zu erhalten.One of the most common causes of vehicle theft is the relative ease with which an ignition key can be owned or remanufactured. It happens too often that the driver does one. Leaves the ignition key in the ignition lock. On the other hand, it is relatively easy for a thief to obtain a copy of a key with the help of an imprint or simply by reading the code number stamped on the key.

Es sind bereits verschiedene Maßnahmen zur Verringerung dieses Risikos vorgeschlagen worden, beispielsweise ein akustisches Warnsignal, das ertönt, wenn das Abziehen des Schlüssels vergessen wird ; das Unterlassen des Einprägens der Codenummer auf dem Schlüssel usw. Durch diese Maßnahmen konnte das Diebstahlsrisiko jedoch nicht völlig beseitigt werden.Various measures to reduce this risk have already been proposed, for example an acoustic warning signal which sounds when the key is forgotten; refraining from embossing the code number on the key, etc. However, these measures did not completely eliminate the risk of theft.

Aus der FR-A2428130 ist es bekannt, am Zylinderkern eines Zündschlosses eine Scheibe mit einer Aussparung zu befestigen, in die zum Sperren der verlängerte Tauchkern eines Elektromagneten eingreift. Der Elektromagnet wird durch einen Stromkreis betätigt, der eine zusätzliche 'Sicherheitseinrichtung, insbesondere ein zusätzliches Schloß zu seiner Steuerung erfordert.From FR-A2428130 it is known to fasten a disk with a recess on the cylinder core of an ignition lock, into which the elongated plunger core of an electromagnet engages to lock. The electromagnet is actuated by a circuit which requires an additional security device, in particular an additional lock for its control.

Aufgabe der Erfindung ist es, ein Zündschloß der eingangs genannten Art derart zu verbessern, daß bei hoher Diebstahl- und Betriebsssicherheit" die Steuerung des Elektromagneten auf möglichst einfache Weise erfolgt. Die Erfindung strebt insbesondere die Erhöhung der Sicherheit von Zündschlössern dadurch an, daß infolge einer elektrischen Blockierung des Zündschlosses nur der Besitzer des originalen Zündschlüssels das Fahrzeug in Betrieb setzen kann.The object of the invention is to improve an ignition lock of the type mentioned at the outset in such a way that with high theft and operational security "the control of the electromagnet takes place in the simplest possible way. The invention particularly aims to increase the security of ignition locks in that as a result of electrical blocking of the ignition lock only the owner of the original ignition key can put the vehicle into operation.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Elektromagnet in einem die Anwesenheit des Schlüssels im Schloßzylinder abfühlenden Stromkreises liegt und dieser Stromkreis mit Hilfe eines Steuerstromkreises mit codierter Schaltung schaltbar ist.This object is achieved in that the electromagnet is in a circuit sensing the presence of the key in the lock cylinder and this circuit is switchable with the aid of a control circuit with coded circuit.

Hierdurch erzeugt der Elektromagnet ein Sperren des Schlosses so lange, bis ein Schlüssel eingeführt ist, so daß der Schlüssel zusätzlich zu seiner üblichen mechanischen Schließsicherheit eine weitere Sicherheitsfunktion besitzt. Darüber hinaus wird ein Sperren des Schlosses nur nach Abziehen des Schlüssels bewirkt, so daß eine zusätzliche Tätigkeit eines Kontrollstromkreises nicht erforderlich ist.As a result, the electromagnet locks the lock until a key is inserted, so that the key has a further security function in addition to its usual mechanical locking security. In addition, the lock is only locked after removal of the key, so that an additional activity of a control circuit is not required.

Der Steuerstromkreis mit codierter Steuerung besteht vorzugsweise aus einem Nebenstromkreis einer elektronischen Fernsteuerung für die Ver- und Entriegelung der Fahrzeugtüren.The control circuit with coded control preferably consists of a secondary circuit of an electronic remote control for locking and unlocking the vehicle doors.

Bei einer bevorzugten Ausführungsform ist in dem den Elektromagneten speisenden Stromkreis ein Schalter angeordnet, der sich öffnet, wenn der Motor in Betrieb gesetzt wird. Dadurch wird eine fortgesetzte Speisung des Elektromagneten bei laufendem Motor vermieden.In a preferred embodiment, a switch is arranged in the circuit feeding the electromagnet, which switch opens when the motor is started. This avoids continued feeding of the electromagnet while the engine is running.

Weitere Merkmale des Erfindung sind gegenstand der Ansprüche 3 und 5.Further features of the invention are the subject of claims 3 and 5.

Anhand der Zeichnung, deren einzige Figur eine schematische Darstellung des Zündschlosses gemäß der Erfindung wiedergibt. wird die Erfindung näher erläutert.Using the drawing, the only figure of which shows a schematic representation of the ignition lock according to the invention. the invention is explained in more detail.

Das Zündschloß besteht aus einem Schloßzylinder 1, das mit Hilfe eines Schlüssels 2 betätigt werden kann. Bei einer Drehung des Schloßzylinders 1 aus seiner Ruhestellung wird das Fahrzeug mechanisch entriegelt, und es werden verschiedene (nicht dargestellte) Stromkreise, wie der allgemeine Stromkreis des Fahrzeugs, der Anlasserstromkreis usw., geschlossen.The ignition lock consists of a lock cylinder 1, which can be operated using a key 2. Upon rotation of the lock cylinder 1 from its rest position, the vehicle is mechanically unlocked and various circuits (not shown), such as the general circuit of the vehicle, the starter circuit, etc., are closed.

Der Schloßzylinder 1 weist am Umfang eine Aussparung 3 auf, die sich in der in der Zeichnung dargestellten Ruhestellung in Flucht mit einem Tauchkern 4 eines Elektromagneten 5 befindet. Wenn der Elektromagnet 5 nicht von Strom durchflossen wird, wird der Tauchkem 4 von einer Feder gegen den Schtoßzyiinder 1 gedrückt. Der Elektromagnet 5 jst durch einen Öldruckschalter 6 derart mit Masse verbunden, daß der Elektromagnet 5 nicht von Strom durchflossen wird, wenn der Motor des Fahrzeugs in Betrieb ist; der Druckschalter 6 ist dann offen.The lock cylinder 1 has a recess 3 on the circumference, which in the rest position shown in the drawing is in alignment with a plunger 4 of an electromagnet 5. If current is not flowing through the electromagnet 5, the plunger core 4 is pressed against the firing cylinder 1 by a spring. The electromagnet 5 is connected to earth by an oil pressure switch 6 such that the electromagnet 5 is not flowed through by current when the engine of the vehicle is in operation; the pressure switch 6 is then open.

Zu dem Schloß gehört ferner ein die Anwesenheit des Schlüssels 2 in dem Schloßzylinder 1 abfühlender Stromkreis, der eine Leuchtdiode 7 und einen Fototransistor 8 umfaßt. Ein Signalgeber 9 einer Fernsteuerungseinrichtung für die Ver- und Entriegelung der Fahrzeugtüren wirkt auf einen Empfänger 10 ein, der mit dem Fahrzeug verbunden ist. Die von dem Empfänger 10 ausgehenden Signale werden einer elektronischen Steuerschaltung 11 zugeleitet. Diese Steuerschaltung 11 ist mit der Leuchtdiode 7 derart verbunden, daß diese mit Strom gespeist wird, wenn der Empfänger 10 ein Signal zum Entriegeln der Türen (Leitung D) aufnimmt, und daß die Stromzufuhr unterbrochen wird, wenn der Empfänger 10 ein Signal zum Verriegeln der Türen (Leitung V) erhält. Der Fototransistor 8 ist mit der Steuerschaltung 11 verbunden, die den Elektromagneten 5 speist, wenn das von dem Fototransistor 8 zugeführte Signal durch Einführen des Schlüssels 2 in das Schloß unterbrochen wird.The lock also includes a circuit which senses the presence of the key 2 in the lock cylinder 1 and which comprises a light-emitting diode 7 and a photo transistor 8. A signal transmitter 9 of a remote control device for locking and unlocking the vehicle doors acts on a receiver 10 which is connected to the vehicle. The signals coming from the receiver 10 are fed to an electronic control circuit 11. This control circuit 11 is connected to the light emitting diode 7 in such a way that it is supplied with current when the receiver 10 receives a signal for unlocking the doors (line D), and that the power supply is interrupted when the receiver 10 receives a signal for locking the Doors (line V) receives. The phototransistor 8 is connected to the control circuit 11 which feeds the electromagnet 5 when the signal supplied by the phototransistor 8 is interrupted by inserting the key 2 into the lock.

Die Vorrichtung arbeitet wie folgt. Das Fahrzeug stehe still, der Motor sei abgestellt, das Zündschloß befinde sich in Ruhestellung, und die Türen seien verriegelt. Der Druckschalter 6 ist dann (bei angestelltem Motor) geschlossen, aber die Leuchtdiode 7 erhält (bei geschlossenen Türen) keinen Strom. Die elektronische Steuerschaltung führt dem Elektromagneten 5 keinen Strom zu, so daß der Tauchkern 4 in der Aussparung 3 des Schloßzylinders 1 eingerückt ist. Das Zündschloß ist blockiert und bleibt dies auch, selbst wenn die Türen aufgebrochen werden und ein Schlüssel 2 in den Schloßzylinder 1 eingeführt wird.The device works as follows. The vehicle is at a standstill, the engine is switched off, the ignition lock is in the rest position and the doors are locked. The pressure switch 6 is then closed (with the engine turned on), however the light emitting diode 7 receives no current (when the doors are closed). The electronic control circuit does not supply the electromagnet 5 with current, so that the plunger 4 is engaged in the recess 3 in the lock cylinder 1. The ignition lock is blocked and remains so even if the doors are opened and a key 2 is inserted into the lock cylinder 1.

Die Betätigung des Signalgebers 9 erzeugt eine Folge von Impulsen, die von dem Empfänger 10 aufgenommen wird. Nach dem Lesen und Vergleicher sendet dieser ein kontinuierliches Signal durch die Entriegelungsleitung D. Das auch der elektronischen Steuerschaltung 11 zugeführte kontinuierliche Signal bewirkt, daß der Leuchtdiode 7 Strom zugeführt wird, die nun Licht auf den Fototransistor 8 wirft. Die Steuerschaltung 11, die von dem Fototransistor 8 ein Signal erhält, führt dem Elektromagneten 5 keinen Strom zu.The actuation of the signal generator 9 generates a sequence of pulses which is received by the receiver 10. After reading and comparing, the latter sends a continuous signal through the unlocking line D. The continuous signal also supplied to the electronic control circuit 11 causes the light-emitting diode 7 to be supplied with current, which now throws light onto the phototransistor 8. The control circuit 11, which receives a signal from the phototransistor 8, does not supply any current to the electromagnet 5.

Wenn der Schlüssel 2 in das Zündschloß eingeführt wird, so wird der auf den Fototransistor 8 fallende Lichtstrahl unterbrochen. Die Steuerschaltung 11, die das Entriegelungssignal erhalten hat und nun kein Signal von dem Fototransistor 8 mehr erhählt, schließt den Stromkreis des Elektromagneten 5. Da der Druckschalter 6 geschlossen ist, wird der Elektromagnet 5 erregt und zieht den Tauchkern 4 an, wodurch der Schloßzylinder 1 freigegeben wird und durch Drehen des Schlüssels 2 der Anlasser betätigt werden kann.When the key 2 is inserted into the ignition lock, the light beam falling on the phototransistor 8 is interrupted. The control circuit 11, which has received the unlocking signal and now no longer receives a signal from the phototransistor 8, closes the circuit of the electromagnet 5. Since the pressure switch 6 is closed, the electromagnet 5 is energized and attracts the plunger 4, causing the lock cylinder 1 is released and the starter can be operated by turning the key 2.

Sobald der Fahrzeugmotor läuft, öffnet sich der Druckschalter 6, wodurch die Stromzufuhr zu dem Elektromagneten 5 unterbrochen wird, so daß der Tauchkern 4 nicht mehr gehalten und gegen den Umfang des Schloßzylinders 1 außerhalb der Aussparung 3 gedrückt wird, die sich nach dem Drehen des Schloßzylinders 1 nicht mehr in Flucht mit dem Tauchkern 4 befindet. Während des Fahrzeugbetriebes bleibt der Druckschalter 6 offen, und der Fototransistor 8 wird wegen der Anwesenheit des Schlüssels nicht beleuchtet.As soon as the vehicle engine is running, the pressure switch 6 opens, as a result of which the current supply to the electromagnet 5 is interrupted, so that the plunger 4 is no longer held and is pressed against the circumference of the lock cylinder 1 outside the recess 3, which after turning the lock cylinder 1 is no longer in alignment with the diving core 4. During vehicle operation, the pressure switch 6 remains open and the photo transistor 8 is not illuminated due to the presence of the key.

Beim Stillsetzen des Fahrzeuges und Drehen des Schlüssels 2 in umgekehrter Richtung wird der Motor abgestellt so daß der Druckschalter 6 sich schließt, wodurch der Elektromagnet 5 erneut mit Strom gespeist, während die Steuerschaltung 11 weiterhin ihre Funktion ausübt. Der Tauchkern 4 wird angezogen und dringt nicht in die Aussparung 3 ein, während der Schloßzylinder 1 in die Ruhestellung gebracht wird. Beim Herausziehen des Schlüssels 2 wird die Stromzufuhr zu dem Elektromagneten 5 unterbrochen, und der Tauchkern 4 dringt nun in die Aussparung 3 des Schloßzylinders 1 ein, der dadurch verriegelt wird. Beim Betätigen des Signalgebers 9 werden die Türen verriegelt ; das durch die Leitung V gesendete kontinuierliche Signal wird auch der Steuerschaltung 11 zugeführt, die daraufhin die Stromzufuhr zur Leuchtdiode 7 unterbricht. Die Vorrichtung befindet sich nun wieder in dem gleichen Zustand wie vor der Abfahrt.When the vehicle is stopped and the key 2 is turned in the opposite direction, the engine is switched off so that the pressure switch 6 closes, as a result of which the electromagnet 5 is supplied with current again, while the control circuit 11 continues to function. The plunger core 4 is attracted and does not penetrate into the recess 3, while the lock cylinder 1 is brought into the rest position. When the key 2 is removed, the power supply to the electromagnet 5 is interrupted, and the plunger 4 now penetrates into the recess 3 in the lock cylinder 1, which is thereby locked. When the signal transmitter 9 is actuated, the doors are locked; the continuous signal sent by the line V is also fed to the control circuit 11, which then interrupts the current supply to the light-emitting diode 7. The device is now in the same state as before the departure.
