Patent number: 11761235Abstract: A locking device having a guard lock for safety doors includes a mechanical actuator which can be fastened on a movable door part and a housing which interacts with the actuator and can be fastened to a door counterpart. The housing includes a receptor to which the actuator can be inserted, and the housing comprises a locking element which is displaceable between an unlocked position, in which the actuator can be released, and a locked position, in which the actuator can be fixed relative to the receptor. The actuator comprises an engagement tongue having an engagement recess for mechanical operative engagement with a head end of a locking element in form of an engagement plunger, the engagement plunger being guided in the housing so as to be longitudinally displaceable in a spring-biased manner in the in a plunger longitudinal direction relative to an inner fixed bearing.Type: GrantFiled: April 29, 2022Date of Patent: September 19, 2023Assignee: K.A. Schmersal Holding GmbH & Co. KGInventors: Christian Uhlenbrock, Thomas Buchwald, Yasar Cevic, Tobias Gerbracht

Patent number: 8413765Abstract: An electronic safety system for an elevator with a controller, which is coupled to a motor for driving an elevator car, a safety controller and a bus by means of which the controller can communicate with bus nodes which receive data from at least one sensor. The controller can communicate with a safety circuit which can be put into an open state by the safety controller, as a result of which the motor is shut off, and the safety circuit has a means which notifies the controller of shut-off of the motor, or shut-off of the motor can be detected by the controller on the basis of the data transmitted from the bus nodes to the controller.Type: GrantFiled: August 13, 2010Date of Patent: April 9, 2013Assignee: K.A. Schmersal Holding GmbH & Co. KGInventor: Christoph Stratmann
