Abstract

Three discs carrying magnets may be used, and each disc has a lost into which a tongue on a locking bar can fit. The magnet on each disc may be fastened in a different angular position relative to the slot. The placing of the magnets on the key is such that when the key is fully inserted the slots are aligned with the tongues on the locking bar, which can then slide so that a fourth tongue slides clear of a groove in the end of the padlock shackle. The shackle is spring loaded. The locking bar has a projection engaging a camming groove in the othr end of the shackle, so that the locking bar is pushed into its locking position when the shackle is pushed down to its fullest extent.
