Easily installed and non-defacing security latch

摘要

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.
