Abstract
An electromagnetic door lock which uses an electromagnet in addition to a latch to maintain the door in the locked position. The lock has hinged handles that unlock the latch when they pivot. When the latch moves to an unlocked position it operates a reed switch which turns off the electromagnet. The latch can also be unlocked by a remotely controlled solenoid. Key operated locks allow only persons with a key to be able to move the pivoting handles.
Claims19
An electromagnetic door locking system for use with a door engageable with a door frame, the door being movable between a closed position in which the door is in mating engagement with the door frame and an open position in which the door is out of mating engagement with the door frame, said electromagnetic door locking system comprising:
- a latch movable between a locked position and an unlocked position, said latch engagable with a cavity of the door frame when said latch is in said locked position;
- a first ferromagnetic core adapted to be fixed to the door, said first ferromagnetic core overlying a first portion of the door frame when the door is closed;
- a first electromagnet adapted to be fixed to the door frame, said first electromagnet being in registry with said first ferromagnetic core when the door is closed, said first electromagnet exerting a force on said first ferromagnetic core to maintain the door in the closed position when said first electromagnet is energized;
- and
- a solenoid operably linked to a pusher plate adapted to be disposed within the cavity, whereby said latch is pushed out of the cavity by said pusher plate when said solenoid is energized.
