Definitions

  • the invention relates to a security lock with an electromechanical lock that can be actuated, for example, by an electromagnet or electric motor, which can also be actuated mechanically by a key in the event of malfunctions, in particular a power failure, via a tumbler.
  • Security locks of the type described above are known in particular for prisons. They are operated electromechanically by an operator in a control center. The operation on site can only be carried out mechanically with the help of a suitable key.
  • the invention is therefore based on the object of developing the known security lock in such a way that it can be actuated electro-mechanically while maintaining the necessary security on site, ie independently of the control center.
  • the solution to this problem by the invention is characterized in that the electromechanical actuation of the bolt can additionally be triggered by a switch which can be actuated by a part of the tumbler mechanism that can only be moved by a key with a suitable lock.
  • the security lock As a result of the further development of the security lock according to the invention, it can thus be actuated electro-mechanically by an authorized person directly at the door, independently of the control center, without the need for a full mechanical opening of the lock, although the authorized person does not have the option of to carry out such a change in the case of a security lock with switchable tumblers. By switching off the current, if necessary, it can be ensured that an electro-mechanical actuation on site is not required.
  • the tumbler comprises locking tumblers operated directly by the key and locking tumblers arranged on a tumbler shaft, which can be coupled to the tumbler shaft when the locking tumblers are properly arranged and can be coupled relative to the tumbler shaft with the tumbler shaft, which in turn actuates the switch.
  • the closure of the tumbler mechanism can preferably be changed in a manner known per se by differently setting each locking tumbler on a retaining pin.
  • the angle of rotation of the key which triggers the electro-mechanical actuation of the bolt is limited. In a preferred embodiment of the invention this is achieved in that in the lock housing, i.e. a stop protruding into the range of movement of the key is arranged on the lock plate or on the lock cover.
  • the invention finally proposes to provide a key provided for the mechanical actuation of the lock with a recess corresponding to the stop .
  • the lock shown in the view without a lock cover comprises a lock plate 1, which is provided with a faceplate 1a and with a total of four threaded bushings 1b for fastening the lock cover, not shown.
  • a bolt 2 is slidably mounted, which is guided with its bolt head 2a in a recess in the face plate 1a and by means of an elongated hole on a bearing pin 1c, which is arranged on the lock plate 1. Due to a ramp 2b on the bolt head 2a, the bolt 2 is designed as a latch bolt. In the closed position, the bolt head 2a of the bolt 2 engages in a recess in a strike plate 3, which is attached to a door frame 4 according to FIGS. 9 and 10.
  • the latch 2 can be actuated either electro-mechanically or by a key-operated mechanical locking mechanism.
  • a solenoid 5 is provided for electro-mechanical actuation.
  • the mechanical locking mechanism comprises a set of height-adjustable locking tumblers 6 arranged on the lock plate 1 and an associated set of convertible locking tumblers 7, which are also height-adjustable on a tumbler shaft 8 and interact with a retaining pin 1d arranged on the lock plate 1.
  • the armature 5a of the lifting magnet 5 interacts with a retraction lever 10, which is pivotably mounted as a two-armed lever on a bearing pin 1e of the lock plate 1.
  • the upper part of the retraction lever 10 comes into contact with a driving mandrel 2c of the bolt 2, so that it can be moved from its extended locking position into a release position with the aid of the solenoid, as it is for example, is shown in FIGS. 2 and 3.
  • a locking slide 11 is provided, which is displaceably mounted transversely to the direction of movement of the bolt 2 by means of elongated holes on bearing pins 1f of the lock plate 1.
  • This locking slide 11 carries on its underside a locking pin 11a, which cooperates with a projection 2d of the bolt 2.
  • a trigger element 12 is provided, which in turn is slidably mounted on the catch pin 2c on the one hand via elongated holes and on the other hand on a bearing pin 2e of the bolt 2 in the longitudinal direction thereof.
  • the trigger element 12 is provided with a control surface 12a for a driving pin 11b arranged on the locking slide 11, so that a movement of the locking slide 11, which moves the locking pin 11a out of the range of motion of the projection 2d, takes place by a relative movement of the trigger element 12 to the bolt 2 that the bolt 2 can be moved between its end positions.
  • a stop mandrel 12b is arranged on the trigger element 12, which, when the retraction lever 10 is pivoted clockwise, in front of the driving mandrel 2c of the bolt 2 is gripped by the retraction lever 10, so that during an electro-mechanical retraction movement of the bolt 2, the locking slide 11 is first raised and thus the locking between the locking mandrel 11a and the projection 2d is released before a retraction force is exerted on the bolt 2 via the driving mandrel 2c.
  • a limit switch 13 is provided in the exemplary embodiment. The respective position of the locking slide 11 is also monitored by a further limit switch 14.
  • the lifting magnet 5 In order to withdraw the bolt 2 with the aid of the lifting magnet 5 in an electromechanical manner with the door closed from the locked position shown in FIG. 1 into its release position according to FIG. 2, the lifting magnet 5 is energized. As a result, its armature 5a is pulled back into the housing, as a result of which the pull-back lever 10 is pivoted clockwise.
  • the trigger element 12 is first relative to the bolt via the stop pin 12b 2 moved so that the control surface 12a lifts the locking slide 11, whereby its locking pin 11a releases the projection 2d of the bolt 2. Due to the further pivoting movement of the retraction lever 10, the latch 2 can thus be retracted into its release position according to FIG. 2 via the driving mandrel 2c. Due to the force of the spring 11c, the locking slide 11 returns to its locking position, as shown in FIG. 2.
  • a control wedge 15 comes into operation, which is arranged parallel to the bolt 2 and, like this, with its head 15a in a recess in the face plate 1a and by means of an elongated hole on a bearing pin 1g of the lock plate 1 is stored.
  • the control wedge 15 is also formed with a run-up slope 15b and is loaded in the extension direction by a compression spring 16.
  • control wedge 15 While the control wedge 15 rests with its end face on the striking plate 3 of the door frame when the door is closed according to FIG. 2, it is moved forward when the door is opened due to the compression spring 16, as shown in the illustration in FIG. 3.
  • the control wedge 15 lifts the locking slide 11 against the force of the spring 11c by means of an elevation 15d formed between two recesses 15c, as shown in FIG. 3.
  • its locking pin 11a releases the projection 2d of the bolt 2, so that it arrives due to the locking spring 9 loading it from the position shown in FIG. 3 to the position shown in FIG. 4, in which the locking head 2a of the latch 2 is in the extended position.
  • the solenoid 5 Since the solenoid 5 is no longer energized, the retraction lever 10 also returns to its starting position according to FIG. 1 by a pivoting movement directed counterclockwise, as is also shown in FIG. 4.
  • the bolt 2 arrives in the recess in the striking plate 3 provided for the bolt head 2a due to the force of the locking spring 9 loading it, so that the bolt 2 again assumes the locking position shown in FIG. 1.
  • the control wedge 15 rests with its end face according to FIG. 1 on the striking plate 3. Since the nose 11d of the locking slide 11 lies in the front recess 15c of the control wedge 15, the locking pin 11a prevents the bolt 2 from being pressed back unauthorizedly with the aid of the projection 2d.
  • the lock is again in the locking position shown in FIG. 1, from which it can be transferred to the release position either by an electro-mechanical actuation using the lifting magnet 5 or by means of a purely mechanical actuation using a key.
  • FIG. 6 shows a key S1 inserted into a key guide hole 1h in the lock plate 1 (see FIG. 1), which - with correct locking, ie design of the key bit - via the tumbler channels 6a, the locking tumblers 6 during a rotation of the kind shown in FIG. 1 Starting position has raised that their coupling projections 6b were exactly in front of the coupling recesses 7a of the locking tumblers 7 fixed on the bearing pin 1g.
  • the lock is equipped with an adjustable tumbler
  • the key S1 in the position shown in FIG. 6 can be removed and replaced by another key, so that when the lock is locked, the locking tumblers 7 with a new lock on the retaining pin 1d be filed. The lock can then only be opened with a key that has the new lock.
  • a switch 17 is provided in the lock, which can be actuated by a part of the tumbler that can only be moved by a key S2 with a suitable lock.
  • this switch 17 is actuated according to FIG. 5 when the tumbler shaft 8 is withdrawn. While the circuit of the switch 17 is open in the locked position of the lock according to FIG. 1, even a slight retraction of the tumbler shaft 8 according to FIG. 5 causes the circuit to be closed, so that the solenoid 5 can be energized via the switch 17 to the to achieve the above-described electro-magnetic transfer of the lock from its locked position to the release position.
  • a key S2 according to FIG. 11 is used.
  • This key S2 has the same lock, ie the same double-sided key bit as the key S1 according to FIG. 12, which was used in the purely mechanical actuation of the lock explained above.
  • a further retraction of the tumbler shaft 8 by the key S2 is prevented by the fact that a pin-shaped stopper 1i is provided on the lock plate 1 in the region of the tumbler channels 6a, which prevents further turning of the key S2.
  • the key S2 can thus only be used for an electro-mechanical actuation of the lock; A purely mechanical retraction of the latch 2 is not possible using the key S2.
  • this key S1 is provided with a recess a corresponding to the stop 1i according to FIG.
  • the switch 17 actuated with the aid of the key S2 by the tumbler shaft 8 thus enables an electro-mechanical actuation of the lock via the solenoid 5 without the opening by a remote control center or by a full mechanical actuation of the tumbler mechanism.
  • the above-described design of the bolt 2 as a latch bolt with a ramp 2b enables the door to be closed by simply pressing it shut. Since the electromechanical actuation of the lock with the aid of the key S2 presupposes that this key S2 has the correct locking, the electromechanical actuation of the lock takes place on site while maintaining the same security as the purely mechanical actuation with the aid of the key S1.
  • the construction described allows a separation between the drive mandrel 8b belonging to the mechanical tumbler and the retraction lever 10 when electromechanically actuated and on the other hand creates an indirect connection via the retraction lever 10 between the mechanical tumbler and the bolt 2 with purely mechanical actuation of the lock using the key S1.
  • the tumbler shaft 8 'according to Fig. 8 is provided via an angle piece 18 with a driving mandrel 18a, which protrudes through a recess 1k in the lock plate 1 and, like the driving mandrel 8b, cooperates with the retraction lever 10.
  • the door can thus be opened either electro-mechanically or purely mechanically by one of the two locks, the two locks being able to have the same or a different lock; in both cases the keys S1 and S2 can be designed with asymmetrical key bits.
