Bumping preventing arrangement for lock device, lock device and method

Abstract

A bumping preventing arrangement (10) for a lock device (38, 52, 68), the bumping preventing arrangement (10) comprising transfer member (12, 46, 64, 74) having a magnet (14), the transfer member (12, 46, 64, 74) being movable along an actuation axis (18) between a locked position (16) and an unlocked position (36); a plurality of electric conductors (20), each electric conductor (20) enclosing the actuation axis (18); and a plurality of switches (22), each switch (22) being associated with a respective electric conductor (20), and being arranged to selectively close an electric circuit comprising the associated electric conductor (20) such that eddy currents are induced in the electric conductors (20) when the magnet (14) moves along the actuation axis (18) from the locked position (16) towards the unlocked position (36). A lock device (38, 52, 68) and a method of controlling a lock device (38, 52, 68) are also provided.
