Reinforced striker assembly for door locks

Claim 2

Means to resist forceable entry through a bolted door which is swingable with relation to a fixed surrounding door frame having a bolt receiving socket and an adjacent striker plate recess, said means comprising a reinforcement plate disposed in the bottom of said recess and having a pair of opposed anchor tabs projecting into said socket and engaging the forward and rear walls thereof, prongs on said reinforcement plate rearward of said tabs and being driven into a door jamb rearward of said socket to further anchor the reinforcement plate, and a conventional striker plate mounted on the outer face of said reinforcement plate and each having a bolt receiving opening in registry with the bolt socket, the conventional striker plate covering and substantially concealing the reinforcement plate from view, and anchor screw means common to the reinforcement plate and said conventional striker plate penetrating into an adjacent door jamb portion, and further penetrating the adjacent wall stud.

Claim 3

The structure of claim 1, and said prongs comprising a pair of spaced apart bendable generally L-shaped prongs on a rearward edge portion of the reinforcement plate which are initially elevated from the plane of the reinforcement plate and adapted to be driven down to lie in said plane with pointed portions of the prongs penetrating the jamb substantially at right angles to the reinforcement plate.

Claim 4

The structure of claim 1, and a rearward offset extension on the reinforcement plate between said prongs including an inturned flange adapted to engage the adjacent jamb portion for further anchorage of the reinforcement plate.

Claim 5

The structure of claim 3, and a weather strip element overlapping said prongs and rearward extension and concealing them from view immediately rearwardly of the conventional striker plate, the latter being flush with said jamb.

Claim 6

The structure of claim 1, and said anchor screw means comprising a pair of apertures in said reinforcement plate and conventional striker plate above and below said bolt socket and being in registry, and a pair of screws extending through said apertures and penetrating into said door jamb above and below said bolt socket.

Claim 7

The structure of claim 5, and a third longer anchor screw for the reinforcement plate and rearwardly of the conventional striker plate and bolt socket and offset from said pair of screws, said third anchor screw penetrating through said jamb and into an adjacent wall stud.

Claim 8

The structure of claim 6, and a weather strip element on said jamb vertically and overlying and concealing said third anchor screw and adjacent parts of said reinforcement plate.

Claim 9

A reinforcement plate for application at one side of a door jamb ahead of a stop rail and in underlying relation to the conventional striker plate and adjacent a door bolt socket said jamb, said reinforcement plate comprising a rectangular plate body having a substantially central rectangular bolt receiving opening and a pair of anchor screw apertures above and below said opening, a pair of right angular locating and anchoring tabs on said plate body projecting beyond one side thereof at the sides of said bolt receiving opening which are vertical during use, integral substantially L-shaped pointed prongs on the two rearward corners of the plate body and being elevated from the plane of the plate body prior to being driven downwardly into use positions, a rearward tongue extension on the plate body between said prongs having an anchor screw aperture offset rearwardly from said screw apertures and spaced rearwardly, of said bolt receiving opening and said tabs, and a short generally right angular flange on the rearward end of said tongue extension facing in the direction of said prongs.

Claim 10

A reinforcement plate for application at one side of a door jamb ahead of a stop rail and in underlying relation to the conventional striker plate and adjacent a door bolt socket said jamb, said reinforcement plate comprising a rectangular plate body having a substantially central rectangular bolt receiving opening and a pair of anchor screw apertures above and below said opening, a pair of right angular locating and anchoring tabs on said plate body projecting beyond one side thereof at the sides of said bolt receiving opening which are vertical during use, integral substantially L-shaped pointed prongs on the two rearward corners of the plate body and being elevated from the plane of the plate body prior to being driven downwardly into use positions, a rearward tongue extension on the plate body between said prongs having an anchor screw aperture offset rearwardly from said screw apertures and spaced rearwardly, of said bolt receiving opening and said tabs, and a short generally right angular flange on the rearward end of said tongue extension facing in the direction of said prongs.
