Definitions

  • the invention relates to a motorized actuating element for a central locking system, which has a lock rod provided for actuating a door lock, coupled with a button rod and movable between two end positions by means of a motor, and a locking device for theft protection.
  • a motorized actuating element for a central locking system which has a lock rod provided for actuating a door lock, coupled with a button rod and movable between two end positions by means of a motor, and a locking device for theft protection.
  • Such actuators are installed in central locking systems of today's motor vehicles and are generally known.
  • the button bar is firmly connected to the lock bar.
  • the lock bar In the anti-theft position, the lock bar is immovably blocked so that a burglar cannot pull the lock bar up by pulling the end of the associated button bar after a window has been opened violently, thus unlocking the lock and then opening the door.
  • the anti-theft device can only be removed with the key by actuating an electrical contact in the lock and thereby releasing the lock by a motor.
  • a disadvantage of the known central locking systems is that the anti-theft device can no longer be unlocked if the vehicle electrical system fails. For this reason, the driver's door is not equipped with such an anti-theft device and instead there is a mechanical anti-theft device that can be operated using the key. As a result, at least the driver's door can still be opened in the event of a failure of the vehicle electrical system.
  • a disadvantage of such a central locking system is, of course, that the anti-theft protection of all doors can only be carried out by means of the key on the driver's door.
  • the invention has for its object to design a motorized actuator of the type mentioned in such a way that even without energy supply via the vehicle electrical system, all door locks can be opened if their anti-theft device is switched on and which can be actuated by all doors having a lock cylinder in the presence of on-board voltage .
  • the anti-theft device is formed by a motor-driven bolt which limits the displaceability of the lock rod and is held in the unlocking position by spring force, and for the actuation of the motor of the bolt in the locking direction there is provided a limit switch which rests against the lock rod and that in the closed position of the lock rod below the limit switch, a control area is provided in the lock rod for switching the limit switch.
  • Such an anti-theft device is an anti-theft device.
  • the lock bar is only temporarily locked when it is pulled and the limit switch is thereby actuated. Since the motor moves the bolt in the locking direction and in the event of a failure of the vehicle electrical system, the bolt is pretensioned in the unlocking position by spring force, if the vehicle electrical system fails, it cannot happen that an anti-theft door cannot be opened with the key.
  • the actuating element according to the invention thus creates a theft protection requirement, which only secures the lock bar if it is pulled up slightly by means of the security button rigidly connected to it while the anti-theft device is switched on, without the open position being reached. Multi-door actuation is possible with the actuating element according to the invention. It is no longer necessary to provide the driver's door with an anti-theft device that can be mechanically operated by the key.
  • the limit switch can be actuated particularly easily by slightly shifting the lock rod if the control area is formed by a control groove in the lock rod.
  • the motor for moving the bolt is particularly simple and therefore inexpensive if it is a solenoid.
  • the electrical connection of the actuating element is also very simple if, according to another embodiment of the invention, the bolt is pretensioned in the unlocked position by a spring and the limit switch is designed to close a supply circuit of the magnetic coil.
  • a very particularly advantageous embodiment of the invention consists in that for latching the bolt with the lock rod on the lock rod, a folding hook is provided which is pivotable by means of a spring in a central position and which is pivotable about an axis provided on its lower side within a region which permits latching with the bolt is.
  • a folding hook is in the anti-theft state when pulling up the lock rod with pretension against the bolt.
  • the control element is very well suited for pneumatic central locking systems.
  • the lock rod is advantageously connected directly to a membrane of a pneumatic servomotor.
  • the actuating element according to the invention can also work by an electric motor, in that the lock rod is driven by means of a spindle nut of a threaded spindle which can be driven by an electric motor.
  • the actuator shown in Figure 1 has a lock rod 1 in a housing, not shown, which is connected directly to a membrane 2 of a pneumatic motor 3, partially shown.
  • a folding hook 4 is pivotally arranged about an axis 5 extending transversely to the lock rod 1, the axis 5 supporting the folding hook 4 on its lower side.
  • Two stops 6, 7, between which a leaf-shaped spring 8 is arranged, are schematically indicated on the folding hook 4. If you swivel the folding hook 4, depending on the pivoting direction, the stops 6 or 7 move against the spring 8 and deform them so that the folding hook 4 is reset by the spring 8 when it is released. In the spreading direction, the pivotability of the folding hook 6 is limited by a stop 9 on the lock rod 1.
  • a limit switch 13 is used to switch on the solenoid coil 11, which bears against the lock rod 1 with a button 14 and is in the position shown in the open position. Also indicated in FIG. 1 is a lock cylinder 15, which can be actuated with a key, with a switch 16, and the switching of the solenoid 11 with the limit switch 13.
  • a control area in the form of a control groove 17 is provided on the lock rod 1, into which the button 14 is able to reach when the lock rod 1 moves correspondingly upwards. If the button 14 reaches the control groove 17, the limit switch 13 closes.
  • Figure 2 shows the actuator in the closed position.
  • the folding hook 4 is located immediately below the bolt 10 and the control groove 17 immediately below the button 14 of the limit switch 13.
  • the solenoid 11 is not energized, however, so that the bolt 10 is retracted exactly as in FIG.
  • FIGS. 4 and 5 show that the principle according to the invention can also be used with an electromotive adjusting element.
  • the lock rod 1 in this embodiment has a coupling piece 18 which can be raised or lowered together with the lock rod 1 by means of a spindle nut 19.
  • the lock nut 19 is screwed onto a threaded spindle 20, which in turn can be driven via a gear 21 and an electric motor 22.
