ABSTRACT:
An interlocking door guard securely covers and is attached to the outside of doors that open inward. It uses a full length pendulum torsion rod assembly on the hinge side of the door as well as guides in connection therewith and matching receptacles in and/or on both vertical casing members to accommodate mating sections of door guard. The forward section has an open area adequate to access door locks. This area is further protected by adjustable guard bars. Hinge lever assemblies attached to the door and guard in the forward area cause it to shift and interlock and disengage both vertical casing members when encountering stop plates on forward casing receptacles.
