Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
239 words
A lock strike plate assembly comprising a keeper plate for attachment to the facing of a door jamb, an opening defined in a central portion of said keeper plate, a lock bolt housing rigidly mounted on said keeper plate for insertion into a recess in the facing of a door jamb, said lock bolt housing including a pair of opposed parallel side walls each connected at one edge to said keeper plate on opposite sides of the opening in said keeper plate, and a pair of opposed top and bottom walls each connected at one edge of said keeper plate on opposite sides of the opening in said keeper plate, and a rear wall opposite said keeper plate opening and connected at all four of its edges to said walls, a rectilinear support rod rigidly mounted at one of its ends directly to said rear wall and extending in a direction apoproximately perpendicular to the plane of said keeper plate for insertion into a bore extending through a door facing and into wall studs and the like adjacent the door facing, whereby the support rod derives support from the wall studs to hold the lock bolt housing in position in the door facing and the lock bolt housing derives support from the recess in the facing of the door and from the wall studs to hold the lock strike assembly in its proper position at the door jamb facing.
Claim 2
Dependent Claim

Claim 4
Dependent Claim
198 words
A lock strike plate assembly comprising a keeper plate for attachment to the facing of a door jamb, an opening defined in a central portion of said keeper plate, and a lock bolt housing rigidly mounted on said keeper plate, said lock bolt housing being a rigid three dimensional frame defining a hollow cavity for insertion into a recess in the facing of a door jamb, said lock bolt housing being mounted to said keeper plate in such a manner that the opening of said cavity surrounds and includes said keeper plate opening, a rectilinear brace member rigidily mounted at one of its end directly to said lock bolt housing at a point opposite said keeper plate, said brace member extending in a direction approximately perpendicular to the plane of said keeper plate and being of sufficient length to reach into wall studs or the like adjacent to the door facing whereby the lock bolt housing is inserted into a recess in the facing of a door jamb and the brace member is inserted into the wall studs behind the facing of the door jamb and hold the lock strike plate assembly in position in a door facing.
