ABSTRACT:
Electrically-controlled and manually-actuatable lock devices are provided which can be attached in a simple manner to doors of all types. Given remodeling of existing doors, the cylinder lock present in the respective door can remain. The lock device converts a rotational motion introduced at the outside of the door by the turning of a knob, the rotational motion being conducted to the inside of the door below the lock, into a rotational motion of a cam of a cylinder lock and thus allows a traditional lock to be opened and locked. The rotational motion initiated from the outside is connected to the lock cylinder with the assistance of an electromagnetic coupling device that, in turn, actuates a mechanical coupling device. The electromagnetic coupling device is essentially designed without an air gap. This particular provision enables its operation with very low electrical energy. The lock device can therefore be supplied with electrical energy from very small batteries for years.
