Electromechanical locking device for door leaf, has sliding block that is combined together with device that is position-changeable in guiding rail, and overload safety device that is continuously adjusted by screw nut on spindle

摘要

The device has a door closer including a closer shaft that is rotatably connected with an end of rotatable arms. The other end of the arms is slidably engaged by a sliding block (2) in a guiding rail (3). The block operates together with the device that is position-changeable in the guiding rail. A switch-on and switch off electromagnet (10) includes an armature that causes a direct or indirect actuation of a retaining device. A terminal block has a terminal for a voltage supply of the electromagnet. An overload safety device (14) is continuously adjusted by a screw nut (9) on a spindle (7).
