  • Interlocking protective door shield
    Patent number: 4673204
    Abstract: A generally U-shaped protective door shield that engages the swingable edge of a door defines a bolt opening that is to be aligned with a bolt aperture of an underlying face plate of a bolt or lock mechanism. Common anchoring screws are driven through the shield and the face plate into the door, forming a single integral structure of increased strength and insuring proper alignment. Preferably the face plate has recessed screw holes that receive lips on the shield. These lips may be deformed into the recesses by the anchoring screws.
