Definitions

  • the invention relates to a lock with an electro-mechanically, for example, by an electromagnet or by an electric motor, and / or by a key-operated mechanical locking mechanism latch.
  • DE 39 38 655 A1 shows a security lock with a bolt and a special latch, which can be moved out of its locked position together electromechanically and individually by means of a handle or key.
  • a lock is also known from DE 27 27 882 A1, which has both a latch and a bolt connected to it and provided with a ramp.
  • a spring-loaded locking device is pretensioned via the bevels of the latch and the bolt, which can be unlocked via an electromagnet when a programmable coding device is actuated, and which retracts both the latch and the bolt.
  • the invention has for its object to develop a lock of the type described in such a way that a door provided with such a lock can be closed by simply pressing it even when the bolt is pushed out, without impairing security or allowing tampering.
  • the solution to this problem by the invention is characterized in that the bolt of the lock as a latch bolt with a ramp trained and at least in the extended locking position is blocked by a locking slide, which in turn can be actuated by a control wedge movably guided parallel to the bolt, which is also provided with a ramp which, when the door closes, timed before the bolt's ramp on to the door frame arranged striking plate strikes.
  • the locking slide is movable transversely to the direction of movement of the bolt and control wedge, i.e. slidably or pivotably mounted on the lock housing and provided with a locking pin which interacts with a stop surface on the bolt and with a control lug which interacts with at least one control cam formed on the control wedge.
  • the blocking position of the blocking slide can be monitored by a limit switch.
  • the lock according to the invention is equipped with an electro-mechanical actuation of the rain which can be retracted by a lever against the force of a locking spring by means of an electromagnet
  • the invention proposes to movably mount a release element on the locking shaft which is moved forward by the retracting lever and which Retraction movement of the locking block locking slide transferred from its locking position to a release position. In this way, the security of the lock according to the invention is increased with simple means.
  • the release element is guided in a longitudinally movable manner on the locking shaft and with a stop pin for the retraction lever and with a control surface for one on the locking slide arranged driving pin. In this way, an inevitable interaction of these components is brought about by simple means.
  • the retraction movement of the bolt is effected via the release element located in its rear end position.
  • the invention proposes to also monitor the end positions of the bolt by means of a limit switch.
  • 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 of 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 adjustable 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 release element 12 is provided, which in turn is slidably mounted on the driving mandrel 2c via elongated holes on the one hand and on the other hand on a bearing pin 2e of the rain 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 detected by the retraction lever 10, so that when the bolt 2 is retracted electromechanically, the locking slide 11 is first raised, and thus the locking between the locking pin 11a and the projection 2d is released, before the driving pin 2c a retraction force is exerted on the bolt 2.
  • 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 displaced relative to the latch 2 via the stop mandrel 12b, so that the control surface 12a lifts the locking slide 11, whereby its locking mandrel 11a releases the projection 2d of the latch 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, due to the locking spring 9 loading it, it moves from the position shown in FIG. 3 to the position shown in FIG. 4, in which the locking head 2a of the bolt 2 in the extended Position is.
  • 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 locking 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 the coupling projections 6b exactly in front of the coupling recesses 7a of the locking tumblers 7 fixed on the bearing pin 1g.
  • the key S1 can be removed in the position shown in FIG. 6 and replaced by another key, so that when the lock is closed, the locking tumblers 7 are placed on the retaining pin 1d with a new lock. 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.
  • the locking tumblers 6 With the key S2, the locking tumblers 6 are properly raised, so that when the key S2 is turned further, the locking tumblers 6 interact with the locking tumblers 7 and the tumbler shaft 8 via its tumbler lock 8a with the aid of the key S2 into that shown in FIG. 5 Position can be withdrawn, in which the switch 17 energizes the Solenoid 5 triggers.
  • 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 key S1.
  • the construction described enables a separation between the drive mandrel 8b belonging to the mechanical tumbler and the retraction lever 10 in the case of electro-mechanical actuation and, on the other hand, creates an indirect connection between the mechanical tumbler and the retraction lever 10 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 with a driving mandrel 18a via an angle piece 18, which protrudes through a recess 1k in the lock plate 1 and just 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.
