ABSTRACT:
A door secured system includes a door reinforcing rigid metal member (20) across the width of a presently installed door or imbedded within the construction of a new door (20a) to prevent the breaking in of the center of th edoor (panel, rails, etc.) having an L-shaped end at the strike area (24) to strength the lock and strike area. On a presently installed door, fingers (26, 26a & 26b) at the hinge side of the reinforcing rigid metal member (20) with a special hinge (28 and 30) and pin (27) combination five added strength to the hinge system. This also allows easy removal on special occasions. The reinforcing rigid metal member (20a) within the construction of a new door has an L-shaped end (62) for securely attaching a hinge plate (not shown), giving added strength to the hinge side of the door. The rigid metal member (20+20a) has an opening (22) to encompass a cylindrical door lock assembly (46) or dead bolt lock assembly (44). These systems give the same security when in or away from the dwelling. A strike plate (48, 48a or 48b) and hinge plate (30) are to extend a distance so as to permit screws (34) to penetrate not only into the jambs, which generally is the case, but also into the wall studs (38 & 38a). A door-peep strike plate (48b) permits the door to open far enough to see, hear, and talk to someone on the other side and pass articles through without unlocking the dead bolt lock (44). assuring safety. A reinforcing rod (40) penetrates through the edge of the door (42), both hinge plates (28 and 30), door jamb (36) and into the stud (38), preventing the removal of the door, while locked, if the hinge pins are removed. This also gives additional resistance and support strength in the hinge arear (28 & 30).
