Magnetic Door Latch Blocker
US Patent:

Filed:
Apr 12, 2012
Appl. No.:
13/445028
Inventors:

International Classification:
B32B 3/06
US Classification:
428 99
Abstract:
A magnetic latch blocker comprises an oblong flexible strip, one side of which is magnetized so that the strip will magnetically adhere to a metallic door jamb and cover the strike plate of a door. The magnetic strip has a sufficient width to cover the strike plate but not protrude much beyond the door jamb when the door is closed. In practice, the magnetic latch blocker strip would ordinarily remain fastened over the strike plate of the door, which would be left in the locked configuration. When the room was in use, the door would be closed with the locking latch blocked by the magnetic strip. Upon a “lock down” order being issued, someone within the room would partially open the door and pull out the magnetic strip, thereby releasing the latch and locking the door by pulling it fully closed.
