ABSTRACT:
An inexpensive and easy to install and use door security apparatus which comprises a bar extending, in a first position, across the width of the inner side of the door and having end portions which extend beyond the door edges respectively. Brackets attached to the frame portions hold the end portions against the respective frame portions to counteract a force applied to the outer side of the door during an attempted forced entry. A handle is attached to the bar for pivoting it to another position clear of the door so that the door can be opened. The handle extends through the respective frame portion so that it may be operated from the outer side of a door and is lockingly secured to prevent unauthorized persons from operating the handle. In accordance with another aspect of the present invention, at least two locking assemblies are provided with at least one locking assembly provided along each vertical edge of the door. Each of the locking assemblies comprises a pair of members one of which is attached to the door adjacent the respective edge and the other of which is attached to the respective frame portion. The two members are positioned relative to each other so that their barrels removably receive respective legs of a U-shaped bolt to thusly lockingly attach the members together to prevent unauthorized entry.
