    摘要: A KEY AND PADLOCK COMBINATION COMPRISED OF A HOUSING, BOW, LOCKING MECHANISM AND MAGNETIZED KEY. THE LOCKING MECHANISM INCLUDES A CYLINDER RECEIVED WITHIN THE HOUSING AND A BOLT CARRIED BY THE CYLINDER FOR MOVEMENT INTO AND OUT OF LOCKING ENGAGEMENT WITH NOTCHES IN THE BOW. A PLURALITY OF ROTATABLE MAGNETIC TUMBLERS ARE CARRIED WITHIN THE CYLINDER TO NORMALLY HOLD THE BOLT IN THE LOCKED CONDITION.

    WHEN THE KEY IS INSERTED INTO A KEYWAY IN THE CYLINDER, THE TUMBLERS ARE ROTATIONALLY ALIGNED BY THE MAGNETIC FIELD OF THE KEY IN SUCH A WAY AS TO PERMIT DISENGAGEMENT OF THE BOLT FROM THE BOW, THEREBY UNLOCKING THE PADLOCK.
