Abstract

Abstract An improved door lock protector assembly is provided. The assembly consists of a protective device to be mounted on the open-end of a hinged door and a shaped shield to be mounted around the door jamb and stop rail. The door mounted device contains escutcheon plates to provide protective strength to the door panelling in the vicinity of the lock and on the outside of the door a flange to prevent the insertion of a flexible tool between the door and the jamb for the purpose of forcing the lock bolt away from engagement in the jamb. The jamb shield serves to protect the jamb and stop rail in the vicinity of the lock to prevent the breaking of the jamb by a force against the door or the prying loose of the stop rail.
