Abstract

An apparatus for reinforcing a door jamb of the type having an inner bolt receiving face and a perpendicular outer face normally covered by a decorative molding. The apparatus comprises a first flat elongate metal plate adapted to be mounted flush with a portion of the inner bolt receiving face of a door jamb and including a hole defining a bolt receiving opening and a plurality of spaced apart openings adapted to receive mounting screws. A second elongate metal plate having an L-shaped cross-section and including a first side adapted to overlie the first metal plate and a second side including a second bolt receiving opening and a second plurality of spaced apart holes defining second mounting screw openings adapted to receive mounting screws. The second elongate metal plate is slidably inserted beneath a portion of the decorative molding and to lie in contacting abutting relation with a portion of the outer face of the door jamb. The openings in the first and second metal plates correspond so that they can be attached to a door frame in overlying contacting abutting relation with each other and with the door jamb with mounting screws to strengthen the door jamb.

Claims

1. An apparatus for reinforcing a door jamb of the type having an inner bolt receiving face and a perpendicular outer face normally covered by a decorative molding and comprising:

a first flat elongate metal plate adapted to overlie a portion of the inner bolt receiving face of a door jamb and including a hole defining a bolt receiving opening and a plurality of spaced apart openings adapted to receive mounting screws;

a second thin elongate metal plate having an L-shaped cross-section and including a first side adapted to overlie the first metal plate and a second side, said first side including a second bolt receiving opening and a second plurality of spaced apart holes defining second mounting screw openings adapted to receive mounting screws, said second side of the second elongate metal plate being adapted to be slidably inserted beneath a portion of the decorative molding and adapted to lie in contacting abutting relation with a portion of the outer face of the door jamb, and wherein said second bolt receiving opening and said second mounting screw openings corresponding to the respective openings in said first plate;

whereby said first plate and said second plate can be connected to a door jamb in overlying contacting abutting relation with each other and with the door jamb to strengthen the door jamb.

2. An apparatus for reinforcing a door jamb according to claim 1 wherein said first and second metal plates are between about 24 and about 80 inches in length.

3. An apparatus according to claim 2 wherein openings in the second plate that are adapted to receive mounting screws are countersunk to increase the structural interconnection between the first and second plates when they are screwed to the door jamb.

4. An apparatus according to claim 1 wherein said first and second mounting plates are fabricated from 18 gauge metal.

5. An apparatus according to claim 1 wherein said second side of said second metal plate is less than one-half inch in length.

6. The apparatus according to claim 1 wherein said second side of said second metal plate has a thickness that enables it to be mounted beneath the door frame molding without requiring the removal thereof.
