<p>According to the invention a door (1) presents a drive device (3) embodied as a plate fitting for the manual and motor-driven actuation of a locking cylinder (3). The drive device comprises a drive shaft (11) for transmitting a rotation to a locking cylinder (2), a turning handle (15) for manually turning the drive shaft (11) and a drive motor (18, 19) arranged in said turning handle (15) for the motor-driven rotation of the drive shaft (11). A driving toothed wheel (12) is mounted on the drive shaft (11) in a non-rotating manner and is connected with the turning handle (15) such that it transmits a torque. The drive motor (18, 19) can be coupled to the plate fitting in a non-rotating manner and to the driving toothed wheel (12) by means of a coupling (21) if a current is applied.</p> |
