Abstract:
1. A wirelessly controlled electric lock, comprising a lock body ( 2 a ), a key cylinder ( 2 b ), a turn spindle ( 3 ) rotatable by a handle element ( 3 a ) internal of the door, the turning of which enables opening of the lock, an opening spindle ( 4 ) rotatable by an opening element ( 5 ) external of the door, a drive link mechanism ( 41 , 20 , 21 , 22 ) enabling the turn spindle ( 3 ) and the opening spindle ( 4 ) to be coupled with each other for a drive link engagement, such that turning of the opening spindle translates also into a turning motion of the turn spindle, and electrically controlled coupling elements ( 10 , 21 , 22 , 24 , 25 , 26 ), wherein the electrically controlled coupling elements include an actuator ( 10 ) which, in a mode activated by an electrical control ( 12 , 31 , 33 ) transmitted ( 32 ) wirelessly to the electric lock, is adapted to fixedly lock a bolt or plunger ( 10 a ) which, in its fixedly locked condition, enables or activates said drive link mechanism to effect the coupling of the drive link engagement in response to rotation of the opening spindle ( 4 ) by handforce, thereby enabling opening of the lock by continued rotation of the opening spindle ( 4 ), and, without electrical control of the actuator ( 10 ), said bolt or plunger ( 10 a ), upon yielding to the weak returning force of a spring or some other force device, is adapted to disable or not to activate the coupling of the drive link engagement as the opening spindle ( 4 ) is rotated.
