Abstract: A compact door barricade apparatus for use on doors is described. The apparatus is equipped with a protective inner case, outer case, door mount, an upper barricade, a lower barricade, barricade pivot links, handles, and barricade latches. Screws or lag bolts are used to mount the barricade latches to the door frame. The door mount connects the apparatus to the door. The barricade pivot links effectively link the movement of the upper barricade to that of the lower barricade. The movement of the handle disposed on the apparatus facilitates the synchronous movement of the upper and lower barricades across the width of the door and door frame, effectively securing individuals within a room.

Abstract: An indoor security barricade designed to create a temporary blockade between a home's inhabitants and any intruders. The indoor security barricade can be deployed either by manual or mechanical means and then locked into position during periods of danger or increased vulnerability. It can also be used in offices, schools, or government buildings in order to isolate active shooters or other hostile intruders. The security barricade is envisioned as a hallway barricade, entrance barricade, and stairwell barricade, although other embodiments may also be possible.
