Abstract
Embodiments of the present invention include door-securing latches that allow an occupant of a room or other space accessed through a door to secure the door, from inside the room or other space, in order to prevent entry or access by others. Embodiments of the present invention provide a mechanically strong and secure latch that cannot be easily broken or compromised by application of force to the door or by insertion of a tool or device between the door and an adjacent door frame to disable the latch, but that can be disabled by a knowledgeable individual, such as an apartment manger seeking to rescue a disabled apartment occupant in an emergency situation.
Claims4
A security latch comprising
- a latch-pin track;
- a door-frame mount having
- a generally flat sheet, with dimpled apertures through which screws mount the door-frame mount to a door frame,
- a flange that is secured against the door frame, preventing the door-frame mount from being pushed outward as well as positioning the door-frame mount so that the latch is flush with the latch-pin track, and
- a tenon arm;
- an articulated latch arm that includes
- a first articulated-latch-arm segment having a first permanent magnet,
- a second articulated-latch-arm segment having a second permanent magnet, and
- a latch-pin that is slideably retained by the latch-pin track when the latch is deployed;
- wherein once the latch-pin is inserted into the latch-pin track, the attraction between the first and second permanent magnets causes the first and second articulated-latch-arm segments to fold together.
