Definitions

  • the invention relates to a door lock in a vehicle for the transportation of people with the features of the preamble of claim 1.
  • a door lock with these features is known (DE 27 43 598 A1).
  • the intrusion of unauthorized persons is prevented in that the door is locked from the outside with a conventional security lock of a type not described in detail, which has no influence on the door drive.
  • the invention has the task of making a generic door lock easy to use.
  • the driver of the vehicle can now perform two measures, unlocking and opening the door, with one hand.
  • the switch which is operatively connected to the locking cylinder, can be used for this, analogous to the usual driver button, that for opening the door is provided by the driver from the inside, or functionally parallel to this, at the same time with or slightly delayed compared to the unlocking key actuation of the locking cylinder to initiate the opening process of the associated door supported by external force (with air pressure or electrically).
  • the electrical switch is actuated only in one direction of rotation of the locking cylinder, namely in the unlocking direction of rotation, while the opposite direction of rotation serves to mechanically lock the door lock when the door is closed.
  • the switch signal of the switch which is preferably designed as a single-pole microswitch
  • the working direction of the controlled door drive is reversed compared to the last expired or still running operating cycle, i.e. after the switch signal to open, the next switch signal will result in the door being closed and vice versa .
  • a certain delay can be observed if necessary, which, for. B. allows removal of the key before inserting the door movement.
  • the switching signal of the electrical switch can also be fed to a central locking system for activating it in the unlocking direction; Repeating the signal when the door is open - which is necessary to close it - has no effect because the unlocked state is already regularly present when the door is open.
  • a second control switch is then expediently assigned to the locking cylinder, which is switched when turning in the locking direction and then supplies the central locking system with a switching signal for its activation in the locking direction.
  • a lock cylinder 1 is shown in FIG. 1 with a key 2 inserted in a neutral key withdrawal position.
  • a nut 4 rotatably mounted in a door plate is coupled, via which a door lock can be mechanically locked in a known manner via levers which are not visible here.
  • a door lock can be mechanically locked in a known manner via levers which are not visible here.
  • Preferably can e.g. B. a door pull handle from the lock or from the lifting mechanism for a lock latch pawl when the nut 4 was rotated into the locking position.
  • a freewheel between the nut 4 and the lock cylinder 1 is usually provided ("key backlash").
  • the lock cylinder 1 can be returned to the key withdrawal position with a torsion spring.
  • the nut 4 carries a cam 5 on its outer upper circumference.
  • the cam 5 represents an operative connection between the locking cylinder 1 and an electrical (micro) switch 6 with supply line 6L, the rocker switch 7 of which is actuated by the cam 5 when the locking cylinder rotates clockwise (starting from the key withdrawal position) is pressed down and actuates a switching plunger 8, which closes a switching contact in the switch 6.
  • a lever 9 is indicated on the nut 4, to which the locking linkage mentioned can be articulated. The lever 9 lies in a different plane than the rocker switch 7 and cannot act on it.
  • the switch 6 is single-pole and has a fixed contact on the ground side. His switching contact is connected via a timer 10 to a switching device 11, which - shown in a highly simplified manner - is used to control a conventional door drive element 12 which, for. B. can be designed as a reciprocating traveling nut drive.
  • a conventional door drive element 12 which, for. B. can be designed as a reciprocating traveling nut drive.
  • the valves, pressure generators etc. normally used in these systems are not shown here for the sake of clarity. Deviating from the figurative representation, a reversible hydraulic or electric door drive can of course also be used.
  • further control inputs of the switching device 11 are at least indicated, to which, for. B. a driver button arranged at the driver's station can be connected.
  • the switching device 11 can have an input for a feedback signal of the door state (open / closed) and an input for a jamming safety signal (drive reversing).
  • the timing element 10 has a signal-delaying effect, ie the switching device 11 can only activate the door drive with a time delay compared to the actual generation of a switching signal at the switch 5. It goes without saying that the timing element per se can also be integrated into the switching device 11. This arrangement has the advantage that the mechanical door unlocking is carried out before the door drive is pressurized, so that neither a jamming of the lock mechanism caused by its opening pressure nor a sudden impact of the door leaf after mechanical release can occur. If the (pneumatic) door drive responds relatively sluggish anyway, the timer can also be omitted.
  • the nut 4 lies here in alignment with the locking cylinder 1, which is therefore not visible, and which is represented only by hinting at its keyhole 1L, dashed lines in the key withdrawal position and dash-dotted lines in a position rotated by 90 °.
  • the nut now carries a further cam 13 on its lower circumference, which, however, lies in a plane axially offset from the plane of the cam 5 and forms an operative connection of the locking cylinder 1 with a further electrical switch 14.
  • the latter can therefore only be switched by turning the lock cylinder in the locking direction, which Rotation, as mentioned, is associated with a mechanical locking of the door lock.
  • the switch contact of the single-pole switch 14, which is also connected to ground on one side and the switch 6, is connected to a central locking system 15, more precisely to its control unit 15S, which in turn is assigned control elements 15E for the simultaneous unlocking or locking of a plurality of locks, so that at Locking the lock assigned to the lock cylinder 1 - which is usually arranged on the passenger entry side at the front - the other locks can be secured in the same way via the actuating elements 15E.
  • Another control point for the central locking system can be located on the driver's side in a lock cylinder assigned to the driver's door.
  • the switch contact of the switch 6 is now also connected to another input of the control device 15S.
  • the two control switches 6 and 14 can be used to control electrical solenoid valves, via which the reversible control elements can be connected to air pressure.
  • these switches can of course also be used in a manner known per se for controlling an alarm system or other burglar alarm systems.
  • an ongoing opening or closing process of the door drive can also be reversed if necessary by means of the switching signals of the switch 6.
