Definitions

  • the invention relates to a lock with a spring-loaded bolt which can be moved into the open position by a motor, with a tumbler for locking the bolt in the end positions, with an auxiliary latch for piloting the lock and with an end position control of the bolt.
  • Such a lock is known from DE-OS 35 07 349.
  • the bolt is withdrawn via a cam wheel driven by the motor with a rotary cam which acts on a lever which engages with the bolt.
  • the bolt is locked in the retracted position via a catch controlled by the auxiliary latch as long as the auxiliary latch protrudes from the lock, ie as long as the relevant door is open.
  • the catch is released from the bolt, which is brought into the closed position under spring load in this position.
  • the disadvantage here is that the lock can get into a state in which an automatic locking of the bolt can no longer take place.
  • This condition occurs when the auxiliary latch is briefly pushed back, for example unintentionally, when the door is open, so that the catch is released and the bolt is pressed out of the lock.
  • the door closing operation which, in itself, must be carried out to actuate the auxiliary latch to be pushed back and the catch to be made ready.
  • the catch will be locked ineffectively.
  • the invention has for its object to provide a lock of the type mentioned, the functional reliability is improved.
  • a basic idea of the invention is to couple the function of the auxiliary latch and the bolt tumbler to one another in such a way that a perfect actuation of the bolt is ensured in every bolt and auxiliary latch position.
  • a particular advantage of the invention can be seen in the fact that both opening and closing of the bolt can be done briefly by spring support.
  • the invention is based on the fact that the bolt is actuated directly via the springs, which are biased by the motor in the required manner.
  • the bolt movement is therefore independent of the actuating speed of the motor and depends solely on the spring force.
  • the latch can be opened manually in the event of a motor failure or defect, so that the door can be opened easily in the event of danger.
  • the bolt is locked in both end positions safely and exclusively by means of a tumbler, which is released when the bolt is opened either by a key-operated locking cylinder, a door handle or the motor. Furthermore, this tumbler is controlled by the auxiliary latch in such a way that it releases the locking of the bolt when the door is closed, so that it is pressed out of the lock under spring force.
  • FIG. 2 denotes a housing and 3 a striking plate of a lock, which is provided overall with the reference number 1.
  • the cover of the housing 2 is removed, so that the components arranged inside the housing 2 are shown in a side view.
  • the figure shows the state of the lock 1, in which a locking bolt 4 protrudes from the striking plate, ie the locking bolt 4 is located itself in its closed position. In an open position, not shown, the locking bolt 4 is retracted into the housing 2 and is flush with the striking plate 3.
  • an auxiliary latch 5 is shown in the figure, which also protrudes from the striking plate 3, as would be the case if a door (not shown) belonging to the lock 1 is opened. When the door is closed, the auxiliary latch 5 is pushed back from the door frame into the housing 2.
  • the lock 1 can be operated in three different ways: Via a nut 6 which is connected to a door handle (not shown), via a lock cylinder 7 which can be actuated with a key (not shown) or via an electric motor 8 which is controlled and supplied from outside via supply lines 9.
  • the locking bolt 4 is locked in its two end positions by a tumbler 10, which is vertically displaceable transversely to the direction of movement of the locking bolt 4.
  • the bolt path is released by lifting the tumbler 10. This state, in which the tumbler 10 has the greatest upward deflection, is illustrated in the figure.
  • the locking bolt 4 is loaded in the direction of movement by a locking spring 11, which in the example shown is a leg spring with a housing-fixed leg and one with the locking bolt 4 via two pins 13, 14 connected free leg 15 is provided. It is mounted on a bolt 16 fixed to the housing. In the present position, the locking spring 11 biases the locking bolt 4 via the pin 13 in such a way that the locking bolt 4 is retracted into the housing 2 in a flash by spring force when the locking device 10 is unlocked.
  • a locking spring 11 which in the example shown is a leg spring with a housing-fixed leg and one with the locking bolt 4 via two pins 13, 14 connected free leg 15 is provided. It is mounted on a bolt 16 fixed to the housing. In the present position, the locking spring 11 biases the locking bolt 4 via the pin 13 in such a way that the locking bolt 4 is retracted into the housing 2 in a flash by spring force when the locking device 10 is unlocked.
  • the locking bolt 4 is in the open position, ie it is pushed back into the housing 2, the locking spring 11 is brought into engagement with the pin 14 by means of the electric motor 8 and is biased in such a way that the locking bolt 4 is unlocked by the tumbler 10 is pushed into the shown closed position in a flash.
  • the tensioning of the closing spring 11 takes place via a tensioning slide plate 17 which is slidably mounted parallel to the locking bolt 4 via elongated holes 18. It acts on the free leg of the locking spring 11 via a driver running perpendicular to the plane of the drawing, which is not shown in the figure, in order to keep the representation clear.
  • the clamping slide plate 17 is connected via a two-armed clamping lever 19 mounted in a bolt 20 to a driver bracket 21 which is moved via a threaded spindle 22.
  • the threaded spindle 22 is connected to the drive shaft of the electric motor 8 via a gear transmission 23.
  • the two end positions of the driver block 21 are monitored via an end position control 24.
  • this consists of a left-hand side and a right-hand light barrier 25 or 26, which are triggered by a switching flag 27 connected to the carrier block 21.
  • the position of the tensioning slide plate 17 or the biasing direction of the locking spring 11 is determined via the end position control 24 in order to control the electric motor 8 in the required manner, as will be described in the following.
  • the logic evaluation of the output signals of the light barriers 25, 26 takes place in an electronic evaluation unit 43. These are also the output signals from the end position sensor 28, consisting of two microswitches 44, 45 for the locking bolt 4 and a door contact (not shown) which is connected to the auxiliary latch 5 ) fed.
  • the position of the auxiliary latch 5 determines whether the door in question is closed or open via the door contact. The door contact is open when the auxiliary latch 5 is pushed out over the striking plate 3. It is actuated when the auxiliary trap 5 is pushed into the housing 2.
  • the function of the lock 1 is described below using typical examples. The starting position is assumed that the door is closed, ie the door contact is actuated.
  • the locking bolt 4 is in the closed position shown and is locked by the tumbler 10.
  • the locking spring 11 is tensioned by the tension slide plate 17 from the electric motor 8 in the manner shown.
  • the auxiliary trap 5 is pressed into the lock. In this position, the left light barrier 25 and the microswitch 29 are actuated.
  • the electric motor 8 triggers the tumbler 10 when starting via the tension slide plate 17, so that the Lock bolt 4 is released.
  • the locking bolt 4 shoots into the lock by spring force and is locked there again by the tumbler 10.
  • the microswitch 45 is activated.
  • the electric motor 8 continues to run and tensions the locking spring 11 via the tensioning slide plate 17, which thereby acts on the pin 14. This situation is identified by activating the right light barrier 26.
  • the lock 1 is ready to close again.
  • the tumbler 10 is triggered via a trigger lever 29 which can be displaced parallel to the tensioning slide plate 17 and engages on the tumbler 10 via control bevels 30 on a pin 31 arranged perpendicular to the plane of the drawing.
  • the tumbler 10 is deflected via the control bevels 30 when the trigger lever 29 is moved. They run in a V-shape so that they act during a forward and backward movement.
  • the trigger lever 29 is connected to the cocking slide plate 17 via a trigger slide 32.
  • the trigger slide 32 is carried by the tension slide plate 17 during this movement and at the same time carries out a stroke transverse to the direction of movement of the tension slide plate 17 and the release lever 29, so that according to a predetermined Ver a nose 33 is pushed out of engagement with a corresponding latching recess 34 or 35 in the release lever 29.
  • the release lever is only moved at the beginning of the tension slide plate 17, so that the release lever 29 is decoupled from the release slide 32 when the locking spring 11 is tensioned.
  • the trigger slide 32 acts on either the left locking recess 34 or the right locking recess 35.
  • the cylinder bit (not shown) lifts the tumbler 10 via the extension 36 and takes the locking bolt back into the lock via a transport lever 37, this movement being supported by the closing spring 11. After the locking bolt 4 has been pushed back completely, the door can be opened.
  • the electric motor 8 is actuated in such a way that the closing spring 11 is tensioned in the manner described above in order to make the lock ready for closing again.
  • the microswitches 44, 45 are triggered by a switching lever 46.
  • the opening lever 39 is also articulated to the locking bolt 4, so that the locking bolt 4 can be pushed back, for example, when the closing spring 11 fails, via the opening lever 39. In the example shown, this is done by rotating the two-armed opener lever 39 counterclockwise about a bolt 40. To trigger the tumbler 10, the opening lever 39 presses on a two-armed catch 42, the catch of which acts on a driver 47 connected to the tumbler 10.
  • auxiliary latch 5 As soon as the door is opened, the auxiliary latch 5 is released and the door contact is interrupted.
  • the auxiliary trap 5 is biased for this purpose, which is not shown in detail for the sake of a clear presentation.
  • the locking bolt 4 remains locked in the housing 2 by the tumbler 10.
  • the auxiliary latch 5 After closing the door, the auxiliary latch 5 is pushed back and the door contact is actuated. Furthermore, the catch 42 is triggered via an auxiliary latch slide 41 connected to the auxiliary latch 5, which acts on the tumbler 10 in such a way that the locking of the locking bolt 4 is released. Therefore, the locking bolt 4 shoots due to the bias by the locking spring 11 out of the striking plate 3 in the closed position, which is indicated by the microswitch 44. Since it is indicated in this position of the locking bolt 4 via the end position control 24 that the locking spring 11 is in the relaxed state, the electric motor 8 is controlled via the evaluation unit 43 in such a way that the driver block 21 moves into its other end position and the closing spring 11 is excited. The In this way, the lock is returned to the starting position and ready for opening.
  • the locking bolt 4 If the locking bolt 4 is already in the open position and the door is still closed, the situation could arise under certain circumstances that the locking spring 11 is no longer tensioned due to a power failure or a defect. In this state, the locking bolt 4 can be brought into the closed position with the aid of the locking cylinder 7, the locking spring 11 being tensioned at the same time. The lock is thus back in the starting position. It can therefore be opened again via the nut 6 or the locking cylinder 7 - and as soon as the malfunction of the electromechanical components has been remedied, also by actuating the motor.
  • the state of the end position control 24, the end position sensors 28 and the door contact controls the electric motor 8 in such a way that it assumes the end position required for the operational readiness of the lock.
  • auxiliary latch 5 If the auxiliary latch 5 is actuated when the door is open, then a closing of the door is simulated and the tumbler 10 is correspondingly triggered via the catch 42, which leads to the locking bolt 4 being extended and locked in this position.
  • the locking spring 11 is then tensioned as usual. This state, in which the locking bolt 4 is in the closed position when the door is open, is corrected under the control of the evaluation unit 43 after a predetermined time as soon as the auxiliary latch 5 is released again and protrudes from the locking plate 3 what is signaled by the door contact.
  • the electric motor 8 is actuated and the tumbler 10 is triggered by this movement.
  • the locking bolt 4 is then pushed back into the housing 2 by the action of the locking spring 11. This process is carried out after each actuation of the auxiliary latch 5 with the door open.
