A LOCKING, CHECKING AND ACTUATING DEVICE OPERATED BY MAGNETIC MEANS, AND IN PARTICULAR A FERROMAGNETIC LOCK OF THE BARREL TYPE.

摘要

THE INVENTION CONCERNS A DEVICE HAVING A MAGNETIC KEY AND MAGNETIC BARREL IN WHICH THE MAGNETS 8 OF THE KEY 1 COOPERATE BY REPULSION WITH MAGNETS 25-225 EMBEDDED IN TUMBLERS 21-221 WHICH ARE MOVABLE BETWEEN A POSITION IN WHICH THEY LOCK THE LOCK AND A POSITION IN WHICH THE TUMBLERS CLEAR THE INTERFACE BETWEEN THE ROTOR AND THE STATOR AND ALLOW ROTATION OF THE ROTOR. THE STEM 7 OF THE KEY 1 IS IN THE FORM OF A TUBE IN THE WALL OF WHICH THE MAGNETS 8 ARE EMBEDDED AND THE ROTOR IS IN THE FORM OF A SLEEVE 14 IN THE WALL OF WHICH THE TUMBLERS 21 AND 221 ARE DISPOSED. THE SLEEVE 14 HAS IN ITS CENTRE A CYLINDRICAL FERROUS CORE 17 WHICH PERMANENTLY ATTRACTS THE MAGNETS 25 AND 225. THE STATOR 3 WHICH SURROUNDS THE ROTOR 2 IS PROVIDED WITH OPENINGS 26 AND 226 IN WHICH ARE INSERTED THE ENDS OF THE TUMBLERS 21 AND 221 WHICH ARE DEVOID OF A MAGNET. APPLICABLE TO ANY LOCKING AND ACTUATING LOCK. (FIG. 2)
