The drive apparatus has a driveshaft for transmitting rotation to the locking cylinder, a turning handle for manual rotation of the driveshaft and a gear motor disposed in the turning handle for motor rotation of the driveshaft. A driving toothed wheel is disposed on the driveshaft so as to rotate in unison, being connected with the turning handle so as to transmit torque. The gear motor is adapted to be coupled with the escutcheon so as to rotate in unison and with the driving toothed wheel by a coupling when current is supplied.</p> |
