Abstract

A door strike construction and installation method is provided for aid in locating and installing a door strike in a door frame. The door strike of the present invention comprises a strike plate for coupling to a door frame, an opening in the strike plate adapted for receiving a door latch bolt, a dust box coupled to the strike plate at a boundary or perimeter of the opening and adapted to receive the door latch bolt, and one or more center point apertures formed on a generally flat, innermost portion of the dust box and positioned to provide center points for marking one or more positions for drilling into the door frame to provide a space for receiving the dust box and installing the dust box in the door frame.

Claims

1. A door strike comprising:

a strike plate for coupling to a door frame;

an opening in the strike plate adapted for receiving a door latch bolt;

a dust box coupled to the strike plate at a boundary of the opening and adapted to receive the door latch bolt; and

one or more center point apertures formed on a generally flat, innermost portion of the dust box and positioned to provide one or more center points for marking one or more locations for drilling into the door frame to provide a space in the door frame for receiving the dust box.

2. The door strike of claim 1, wherein two or more center point apertures are provided on the generally flat, innermost portion of the dust box and are positioned in alignment with each other.

3. The door strike of claim 2, wherein the center point apertures are positioned on a centerline of the opening in the strike plate of the door strike.

4. The door strike of claim 3, wherein the center point apertures are positioned equidistant from an outer curved perimeter of the opening in the strike plate.

5. The door strike of claim 4, wherein one or more attachment member apertures are provided on the generally flat, innermost portion of the dust box, the attachment member aperture being provided to accommodate one or more door strike attachment members to attach the dust box to the door frame.

6. The door strike of claim 5, wherein one or more strike plate attachment member apertures are provided in the strike plate for the purpose of accommodating one or more strike plate attachment members to attach the strike plate to the door frame.

7. The door strike of claim 1, wherein the generally flat, innermost portion of the dust box is provided with outwardly projecting bumps centered on the one or more center point apertures of the dust box such that the bumps can be utilized to mark positions for drilling.

8. The door strike of claim 5, wherein the one or more attachment member apertures are centered on bumps formed on an outer side of the generally flat, innermost portion of the dust box such that the bumps can be utilized to mark positions for drilling.

9. A door strike comprising:

a strike plate for coupling to a door frame;

an opening in the strike plate adapted for receiving a door latch bolt;

a dust box coupled to the strike plate at the boundary of the opening and adapted to receive the door latch bolt; and

one or more center point bumps formed on a generally flat, innermost portion of the dust box and positioned to provide center points for marking one or more positions for drilling into the door frame to provide a space for receiving the dust box.

10. A door strike comprising:

a door strike place for coupling to a door frame;

an opening in the door strike plate adapted for receiving a door latch bolt;

a dust box coupled to the door strike plate at the boundary of the opening and adapted to receive the door latch bolt; and

a plurality of center point apertures formed on a generally flat, innermost portion of the dust box and positioned in alignment with each other along a center line of the opening in the strike plate of the door strike for the purpose of marking one or more locations for drilling into the door frame to provide a space in the door frame for receiving the dust box.

11. The door strike of claim 10 wherein the center point apertures are positioned equidistant from each other and equidistant from an outer curved perimeter opening in the strike plate.

12. The strike plate of claim 10 wherein one or more attachment member apertures are additionally provided on the generally flat, innermost portion of the dust box, the attachment member apertures being provided to accommodate one or more door strike attachment members to attach the dust box to the door frame.

13. The door strike of claim 11 wherein one or more strike plate attachment member apertures are provided on the strike plate, the strike plate attachment member apertures being provided to accommodate one or more door strike plate attachment members to attach the door strike to the door frame.

14. A door strike comprising:

a door strike plate for coupling to a door frame;

an opening in the strike plate adapted for receiving a door latch bolt;

a dust box coupled to the door strike plate at a boundary of the opening and adapted to receive the door latch bolt;

one or more center point apertures formed on a generally flat, innermost portion of the dust box and positioned in alignment with each other on a center line of the opening of the strike plate of the door strike to provide one or more center points for marking one or more locations for drilling into the door frame to provide a space in the door frame for receiving the dust box, wherein the center point apertures are positioned equidistant from each other and equidistant from an outer curved perimeter of the opening in the strike plate;

one or more attachment member apertures are additionally provided on the generally flat, innermost portion of the dust box, the attachment member apertures being provided to accommodate one or more door strike attachment members to attach the dust box to the door frame; and

one or more strike plate attachment member apertures are provided in the strike plate for the purpose of accommodating one or more strike plate attachment members to attach the strike plate to the door frame.

15. A method of installing a door strike to a door frame comprising:

providing a strike plate for the door strike, the door strike having a flat portion for coupling to a door frame;

providing an opening in the strike plate adapted for receiving a door latch bolt;

providing a dust box coupled to the strike plate at a boundary of the opening and adapted to receive the door latch bolt;

providing one or more center point apertures formed on a generally flat, innermost portion of the dust box and positioned to provide one or more center points of the opening in the strike plate;

locating the generally flat, innermost portion of the dust box on the door frame at a position that is appropriate for receiving the door latch bolt;

marking the locations of the center point apertures on the door frame to provide locations for drilling into the door frame to provide a space in the door frame for receiving the dust box; and

utilizing the marked center points for the purpose of forming the opening in the door frame to receive the dust box.
