1. Release mechanism for an energy harvesting arrangement for an electronic locking system, the release mechanism comprising:
a drive device for driving an electromagnetic generator, the drive device comprising a substantially planar drive device surface;
a harvesting elastic element arranged to force the drive device towards a starting position, and arranged to store mechanical energy from displacement of the drive device from the starting position along a harvesting path;
at least one magnet;
an input device, the input device being movable along the harvesting path, and comprising a substantially planar input device surface arranged to mate with the drive device surface to establish a mating interface; and
an engaging profile arranged offset with respect to the mating interface;
wherein the input device is arranged to engage the drive device by means of a magnetic force, generated by the magnet and acting between the drive device surface and the input device surface, such that the drive device can be displaced from the starting position by movement of the input device a long the harvesting path; and
wherein the engaging profile is arranged to engage the drive device at an engaging position of the drive device, such that further movement of the input device along the harvesting path causes a relative inclination between the drive device surface and the input device surface.
