Abstract

The door lock and jamb strike plates may be stamped or otherwise formed of metal plate of conventional thickness, but include screw passages and receptacles for the screw heads having axes defining oblique angles between the planes of the plates and the screw axes. In the case of the door lock or deadbolt mortise plates, the screw head receptacles and passages are angled away from one another, with their axes oriented away from the knob and latch mechanism therebetween. In the case of the jamb strike plate or jamb deadbolt plate, the screw head receptacles and passages are oriented to pass into the center of the wood structure behind the plate to provide additional strength. The plates may be provided individually or as a kit, with or without screws.

Claims

1. A door lock installation kit, comprising:

a vertically elongated door lock plate defining a plane and a vertical axis, the door lock plate having a back surface, top and bottom edges, and first and second side edges, the plate adapted to be installed vertically on a door frame with the back surface engaging the door frame, a latch passage disposed generally centrally therethrough, the door lock plate consisting of an upper screw passage and screw head receptacle disposed centrally therein and aligned with the vertical axis, a lower screw passage and screw head receptacle disposed centrally therein and aligned with the vertical axis, each screw passage and screw head receptacle having an axis defining an oblique angle with the plane of the door lock plate, the axis of the upper screw passage and screw head receptacle being oriented upwardly and the axis of the lower screw passage and screw head receptacle being oriented downwardly when the plane of the door lock plate is installed vertically, wherein the axes of the screw passages are vertically aligned in the same plane;

a jamb strike plate defining a plane, the jamb strike plate having a back surface, a closure edge, a latch passage disposed generally centrally therethrough, an upper screw passage and screw head receptacle disposed centrally therein and aligned with a vertical axis of the latch passage, and a lower screw passage and screw head receptacle disposed centrally therein and aligned with the vertical axis of the latch passage, each screw passage and screw head receptacle having an axis defining an oblique angle with the plane of the jamb strike plate, wherein the axes of the screw passages are vertically aligned in the same plane, the axis of each screw passage and screw head receptacle extending away from the closure edge of the jamb strike plate and reside within a horizontal plane, wherein the horizontal planes are parallel;

elongate first and second door lock plate attachment screws; and

elongate first and second jamb strike plate attachment screws.

2. The door lock plate installation kit according to claim 1, wherein:

each screw head receptacle defines a protrusion extending from the back surface of the door lock plate; and

each screw head receptacle defines a protrusion extending from the back surface of the jamb strike plate.

3. The door lock installation kit according to claim 1, wherein the jamb strike plate has a curved strike edge portion.

4. The door lock installation kit according to claim 1, further including a door lock set.

5. The door lock plate and jamb strike plate installation kit according to claim 1, wherein the door lock plate and the jamb strike plate each have a thickness between one and three millimeters.

6. A method of manufacturing the door lock installation kit of claim 1, comprising the steps of:

(a) forming the door lock plate by stamping; and

(b) forming the jamb strike plate by stamping.

7. A door lock apparatus, comprising:

a vertically elongated door lock plate, the door lock plate defining a plane and a vertical axis, the door lock plate having a back surface, top and bottom edges, and first and second side edges, the plate adapted to be installed vertically on a door frame with the back surface engaging the door frame, a latch passage disposed generally centrally therethrough, the door lock plate consisting of an upper screw passage and screw head receptacle disposed centrally therein and aligned with the vertical axis, a lower screw passage and screw head receptacle disposed centrally therein and aligned with the vertical axis, each screw passage and screw head receptacle having an axis defining an oblique angle with the plane of the door lock plate, the axis of the upper screw passage and screw head receptacle being oriented upwardly and the axis of the lower screw passage and screw head receptacle being oriented downwardly when the plane of the door lock plate is installed vertically, wherein the axes of the screw passages are vertically aligned in the same plane, each screw head receptacle defining a protrusion extending from the back surface of the door plate.
