A self-latching lock 1 with a bolt 2, catch 3, auxiliary catch pin 4 and reciprocator 5, in which the bolt 2 can be operated via a latch nut 6 or a closing thruster and is cocked for locking action by an elastic element 7 when the door is in the open position, in which, when the door leaf is engaged in the door rabbet, said bolt is released into its extended locking position by the action of at least the auxiliary catch pin 4, and which is provided with a nut-locking or idling device 8, preferably permitting deactivation by electric remote control, for the temporary activation of the latch function. According to the invention, this remotely controllable nut-locking or idling device 8 permits in advantageous fashion the use of self-latching locks even in combination with centrally controlled closure systems.
Self-latching lock (1) encompassing a bolt (2), catch (3), auxiliary catch pin (4), and reciprocator (5), in which the bolt (2) that can be operated via a latch nut (6) or a closing thruster is cocked, when the door is open, by an elastic element (7) for locking action and, when the door leaf is engaged in the door rabbet, is released into its locking position by the action at least of the auxiliary catch pin (4), characterized by a nut-locking or idling device (8) that permits temporary activation of the latch function as well as deactivation preferably by remote electric actuation.
Self-latching lock (1) as in at least one of the preceding claims, characterized by an electrically operated, remotely controllable nut-locking device (8) for selectively preventing the operation of the latch at least on the outside of the door.
Self-latching lock (1) as in at least one of the preceding claims, characterized by a gear-segment lever (74) that is permanently coupled to the gudgeons (63, 64) for driving an electric generator mounted inside the lock (1).
Self-latching lock (1) as in at least one of the preceding claims, characterized in that at least one of the moving parts of the lock and especially the bolt (2) and/or the catch (3) and/or the auxiliary catch pin (4) is/are provided with one or several sensor(s) (10, 11) for the detection of its/their position at any given time.
Self-latching lock (1) as in at least one of the preceding claims, characterized in that the lock (1) incorporates at least one control unit (12) for controlling the electrically operated devices under interpretative utilization of the signals captured by the sensor(s) (10, 11) and in response to instructions sent to the control unit (12) from outside the lock.
Self-latching lock (1) as in at least one of the preceding claims, characterized in that the transceiver unit (13) is a radio transceiver.
Self-latching lock (1) as in at least one of the preceding claims, characterized in that the lock-out extension of the bolt (2) is additionally dependent on the entry of the catch (3) in the striker plate.
Self-latching lock (1) as in at least one of the preceding claims, characterized in that in the catch area at least one of the bolt-guiding elements is provided with an attenuating element for damping the clicking sound when the bolt snaps into its extended lock-out position.
Self-latching lock (1) as in at least one of the preceding claims, characterized in that the bolt guide element connected to the lock case is linked via a bridge element (17) to another lock segment that is connected to the lock case, or is linked to the lock case itself.
Dependencies are inferred from the claim text.
