Reinforcing system for door and door jamb
First Claim
1. A mechanism to be applied to a door jamb that is opposed by a co-operating door edge to strengthen the door jamb to survive forced entry efforts comprisinga first elongated plate sized for mounting on a door jamb surface that is opposed by a co-operating door edge, the first plate having a protruding ramp configured to serve as a strike plate for a latch bolt mounted in a co-operating door and a bolt hole in the first plate proximate the ramp to receive the latch bolt when the co-operating door is closed,a second elongated plate having an inner overlay and an outer flange perpendicular to the inner overlay forming an L-shaped cross-section, a bolt hole in the inner overlay to receive the latch bolt when the co-operating door is closed, a slot in the outer flange proximate the bolt hole in the inner overlay sized to receive and surround the ramp of the first plate when the first plate is nested with the second plate and the bolt hole in the first plate and bolt hole in the inner overlay are aligned,both the first and second plates having holes that are sized to receive screws to hold the plates mounted to the door jamb and that are positioned in the first and second plates to align when the bolt holes in the first and second plates are aligned.

Abstract
A mechanism to be applied to a door jamb that is opposed by a door edge to strengthen the door jamb to survive forced entry efforts includes two elongated, narrow plates sized for mounting on a door jamb surface. One plate has a protruding ramp configured to serve as a strike plate for a latch bolt mounted in the door and a bolt hole near the ramp. The second plate has an inner overlay and a perpendicular outer flange, forming an L-shaped cross-section. The inner overlay has a bolt hole, and a slot in the outer flange near the overlay'"'"'s bolt hole receives the ramp when the plates are nested. The bolt holes in the plates align, as do additional holes in the plates to receive screws to hold the plates mounted to the door jamb.

1. A mechanism to be applied to a door jamb that is opposed by a co-operating door edge to strengthen the door jamb to survive forced entry efforts comprising
a first elongated plate sized for mounting on a door jamb surface that is opposed by a co-operating door edge, the first plate having a protruding ramp configured to serve as a strike plate for a latch bolt mounted in a co-operating door and a bolt hole in the first plate proximate the ramp to receive the latch bolt when the co-operating door is closed, a second elongated plate having an inner overlay and an outer flange perpendicular to the inner overlay forming an L-shaped cross-section, a bolt hole in the inner overlay to receive the latch bolt when the co-operating door is closed, a slot in the outer flange proximate the bolt hole in the inner overlay sized to receive and surround the ramp of the first plate when the first plate is nested with the second plate and the bolt hole in the first plate and bolt hole in the inner overlay are aligned, both the first and second plates having holes that are sized to receive screws to hold the plates mounted to the door jamb and that are positioned in the first and second plates to align when the bolt holes in the first and second plates are aligned.

5. A kit for protecting against a breakage of a door jamb and cooperating door that has an installed door knob lock assembly including a latch bolt adjacent a door edge comprising
a first elongated plate sized for mounting on a door jamb surface that is opposed by a co-operating door edge, the first plate having a protruding ramp configured to serve as a strike plate for the latch bolt mounted in the co-operating door and a bolt hole in the first plate proximate the ramp to receive the latch bolt when the co-operating door is closed, and a second elongated plate having an inner overlay and an outer flange perpendicular to the inner overlay forming an L-shaped cross-section, a bolt hole in the inner overlay to receive the latch bolt when the co-operating door is closed, a slot in the outer flange proximate the hole in the inner overlay sized to receive and surround the ramp of the first plate when the first plate is nested with the second plate and the bolt hole in the first plate and bolt hole in the inner overlay are aligned, both the first and second plates having holes that are sized to receive screws to hold the plates mounted to the door jamb and that are aligned when the bolt holes in the first and second plates are aligned, both the first and second plates having a width narrow enough for mounting on a door jamb surface that is opposed by a co-operating door edge; - and
first and second metal plates for mounting on the cooperating door having one length dimension long enough to span the door knob lock assembly to define upper and lower ends and having a width narrow enough to fit between a door knob and the door edge, the metal plates having a connection means to enable the first and second metal plates to be fastened to each other through holes in the cooperating door, thereby reinforcing the door around the door knob lock assembly to reduce the likelihood of door breakage during an attempted forced entry. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)

14. A kit for protecting against a breakage of a door jamb and a co-operating door that has an installed door knob lock assembly including a latch bolt adjacent a door edge comprising
an elongated, first plate having a protruding ramp configured to serve as a strike plate for the latch bolt mounted in the co-operating door and a bolt hole in the first plate proximate the ramp to receive the latch bolt when the co-operating door is closed, and an elongated, second plate having an inner overlay and an outer flange perpendicular to the inner overlay forming an L-shaped cross-section, a bolt hole in the inner overlay to receive the latch bold when the co-operating door is closed, a slot in the outer flange proximate the hole in the inner overlay sized to receive and surround the ramp of the first plate when the first plate is nested with the second plate and the bolt hole in the first plate and bolt hole in the inner overlay are aligned, both the first and second plates having holes that are sized to receive screws to hold the plates mounted to the door jamb and that are aligned when the bolt holes in the first and second plates are aligned, both the first and second plates having a width narrow enough for mounting on a door jamb surface that is opposed by the co-operating door edge and a length that extends at least two feet; - and
third and fourth shorter plates for mounting on the cooperating door having a length long enough to span the door knob lock assembly to define upper and lower ends, a connection means to enable the third and fourth plates to be fastened to each other through holes in the co-operating door, thereby reinforcing the door around the door knob lock assembly to reduce a likelihood of door breakage during an attempted forced entry, and a width narrow enough to fit between a door knob and the door edge and narrow enough so that when mounted to the co-operating door, the third and fourth plates do not extend past the edge of the door where they could collide with the installed second plate on the door jamb.
