Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • the lock is only locked after removal of the key, so that an additional activity of a control circuit is not required.
  • the control circuit with coded control preferably consists of a secondary circuit of an electronic remote control for locking and unlocking the vehicle doors.
  • 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.
  • the ignition lock consists of a lock cylinder 1, which can be operated using a key 2.
  • a lock cylinder 1 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the pressure switch 6 remains open and the photo transistor 8 is not illuminated due to the presence of the key.
  • 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.
  • 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.
  • 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.
