Abstract

French doors that include a passive door and an active door are kept closed by a plate on a trim over a French door jamb having a flange at one of the sides. Holes in the plate allow it to be screwed into the trim. The flange retains the passive French door in place, but the screw in the hole over the active door can be removed to allow the plate to pivot about the remaining screw so the plate can be bent upward to allow the passive door to open under the flange.

Claims

1. An apparatus for helping keep a pair of French doors that include a passive door and an active door closed comprising

a substantially rectangular plate of a width from side to side mounted on a trim at the top of a French door and a length between two ends of the substantially rectangular plate substantially longer than the width, the substantially rectangular plate having a perpendicular flange at one of the sides, the flange being unitary with the substantially rectangular plate and extending from the substantially rectangular plate at least ½

inch, the flange having a length in a direction parallel to the length of the substantially rectangular plate that is shorter than the substantially rectangular plate and positioned centered along the length of the substantially rectangular plate,

a hole in the substantially rectangular plate near each end of the substantially rectangular plate, the holes being further from the side having the flange than the other side,

the substantially rectangular plate being configured in a size and shape that enables the substantially rectangular plate to be affixed to the inside face of a trim in the gap above French doors at a location where the flange prevents opening the passive door but not the active door and each hole in the substantially rectangular plate is located above each one of the French doors by screws through the holes into the trim, keeping the substantially rectangular plate in place and its flange retaining the passive French door in place, but the screw in the hole above the active door can be removed to allow the substantially rectangular plate to pivot about the remaining screw in the hole above the passive door so the substantially rectangular plate can be bent upward above the top edge of the passive door to allow the passive door to open under the flange.

2. An apparatus as claimed in claim 1 wherein the substantially rectangular plate has rounded corners where the ends and the side that does not have the flange intersect, enabling the substantially rectangular plate to turn without striking a vertical trim piece depending from the trim to which the substantially rectangular plate is affixed when the substantially rectangular plate pivots.

3. An apparatus as claimed in claim 1 wherein the substantially rectangular plate has at least one slide lock bolt receiving aperture.

4. An apparatus as claimed in claim 1 wherein the substantially rectangular plate has at least two slide lock bolt receiving apertures.

5. An apparatus as claimed in claim 4 wherein the substantially rectangular plate is a foot long, the flange is positioned centered along the length of the substantially rectangular plate and each slide lock bolt receiving aperture is positioned so it has an edge 3½

inches from a substantially rectangular plate end.

6. An apparatus as claimed in claim 4 wherein the slide lock bolt receiving apertures include plugs held in place by connectors that are relatively easy to break.

7. An apparatus as claimed in claim 1 wherein the holes are countersunk so that screws holding the substantially rectangular plate against the trim do not impede closure of the doors.

8. An apparatus as claimed in claim 1 wherein the substantially rectangular plate is a foot long and the flange is about four inches long and is positioned centered along the length of the substantially rectangular plate.

9. An apparatus as claimed in claim 1 wherein the flange extends from the substantially rectangular plate ¾

inch.

10. An apparatus as claimed in claim 1, wherein the substantially rectangular plate and flange are metal.

18. An apparatus as claimed in claim 1 wherein the substantially rectangular plate has enough resilience to spring back toward its unbent position after it has been bent upward to allow the passive door to open under the flange.

11. A method of helping keep a pair of French doors that include a passive door and an active door closed comprising

fastening an end of a substantially rectangular plate on the inside face of a trim in the gap above each French door so that a flange on the substantially rectangular plate extends down from the trim by at least ½

inch at a location where the flange prevents opening the passive door but not the active door,

closing the passive door while bending the substantially rectangular plate upward so the closing passive door passes under the flange,

allowing the substantially rectangular plate to resiliently return toward its unbent position,

pivoting the substantially rectangular plate about the fastener of the substantially rectangular plate to the trim until the flange contacts the passive door and a hole in the substantially rectangular plate is adjacent the trim,

passing a screw through the hole into the trim,

whereby the active door can be opened and closed without interaction with the substantially rectangular plate and the screw over the active door can be removed to allow the substantially rectangular plate to pivot about the fastener in the hole above the passive door and bent upward above the top edge of the passive door to allow the passive door to open under the flange.

12. A method as claimed in claim 11 further comprising a preliminary step of removing an existing striker plate from the trim.

13. A method as claimed in claim 11 wherein fastening the substantially rectangular plate on a trim includes positioning the substantially rectangular plate so a hole in the substantially rectangular plate aligns with a hole in the trim to receive a slide lock bolt.

14. A method as claimed in claim 11 wherein fastening an end of the substantially rectangular plate on the trim includes passing a screw through a hole in the substantially rectangular plate and into the trim.

15. A method as claimed in claim 11 wherein fastening the substantially rectangular plate on a trim includes positioning the substantially rectangular plate so a slide lock bolt receiving aperture in the substantially rectangular plate is aligned with a slide lock receiving hole in the trim.

16. A method as claimed in claim 15 wherein the method includes removing a plug from the slide lock bolt receiving aperture in the substantially rectangular plate by breaking connectors holding the plug in the aperture.

17. A method as claimed in claim 11 wherein fastening an end of a substantially rectangular plate on a trim over a French door includes fastening a substantially rectangular plate that has a flange having a length in a direction parallel to the length of the substantially rectangular plate that is shorter than the substantially rectangular plate and positioned centered along the length of the substantially rectangular plate.

19. A method as claimed in claim 11 wherein allowing the substantially rectangular plate to resiliently return toward its unbent position includes allowing the plate to spring back toward its unbent position.
