FIELD: locks.
SUBSTANCE: group of inventions relates to a fitting closing device and fitting actuating assembly. Closing device comprising an output shaft and an input shaft which is connected to the output shaft and drives the output shaft in normal operation and an emergency drive mechanism. Output shaft is further configured to be moved from the operating position to the end position by means of the emergency drive mechanism. Emergency drive mechanism is designed as a single motor with a roller spring. One motor with a roller spring has one spring element in the form of tape, and the one spring element in the form of tape is wound in a state of reduced tension in the form of a spiral and for tensioning one motor with a roller spring is configured for winding an additional roller from winding in the form of a spiral in a state of reduced tension. Emergency drive mechanism is connected to the output shaft by superposition transmission, and the input shaft and the output shaft are connected by superposition transmission.
EFFECT: reduced requirements for the selection of dimensions for the fitting actuating assembly.
