The lock has an outer door (1) and an inner door (3) provided on both sides of a lock chamber (2). An electric motor (4) is connected with drive shafts (8, 9) of the doors by a clutch i.e. electromechanical clutch, over an angle transmission (6), a friction clutch and a tandem transmission. A set of hand-wheels (5) is connected with each other by one of the shafts and with the transmissions, the friction clutch, and drive shafts by another clutch. The former clutch is close to the electric motor during operation and the latter clutch is close to the hand-wheels during emergency. |
