Electric lock for building, has cylinder linked to gear motor through clutch that has displacement unit positioning planetary gear in different positions around axis of drive wheel, where wheel intercepts trajectory of gear

摘要

The lock has a cylinder linked to a gear motor through a clutch that has a drive wheel (11) linked to the motor. The clutch has a planetary gear (12) for the drive wheel and a displacement unit that positions the planetary gear in different positions around the axis of the drive wheel. The drive wheel intercepts the trajectory of the planetary gear.
