Claim 11:
12. A method for operating a lock device of an electronic locking system, the method comprising:
manually rotating an input member a first angular distance in a first direction about an input rotational axis while harvesting energy from the rotation by an energy harvesting arrangement;
moving a selective transfer device from a locking state, in which an output member cannot be rotated about an output rotational axis by means of rotation of the input member about the input rotational axis, to an unlocking state, in which the output member can be rotated about the output rotational axis by means of rotation of the input member about the input rotational axis, with energy from the energy harvesting arrangement; and
rotating the output member about the output rotational axis by manually rotating the input member a second angular distance, beyond the first angular distance, in the first direction about the input rotational axis;
wherein the energy harvesting arrangement comprises:
an electric generator;
a drive member displaceable, by rotation of the input member, from a starting position to a releasing position, the drive member arranged to drive the electric generator by at least displacement of the drive member from the starting position to the releasing position;
an elastic element arranged to store mechanical energy from the displacement of the drive member from the starting position to the releasing position; and
a release mechanism arranged to release mechanical energy stored in the elastic element to a returning displacement of the drive member when the drive member reaches the releasing position.
