Abstract

A combination of a door, a door-jamb and a magneto-mechanical-latching-assembly is provided. The door is mounted to close an opening adjacent to the door-jamb. The latching-assembly operates to secure the door in a closed position. The latching-assembly includes a latch-component and an actuator-component. The latch-component is associated with one of the door and door-jamb. The latch-component includes a latch that includes a latch-magnet having a latch-magnet-polar-axis. The latch is mounted relative to the latch-component to reciprocate along a substantially horizontal and linear latching-path between an extended-latching-position and a retracted-non-latching-position. The actuator-component is associated with the other of the door and door-jamb. The actuator-component includes an actuator that includes an actuator-magnet having an actuator-magnet-polar-axis. The actuator-magnet is mounted relative to the actuator-component to reciprocate along a substantially vertical actuator-path between a latch-magnet-attracting-position and a latch-magnet-repelling-position.

Claims

1. In combination with a door and a door-jamb, wherein the door is mounted to close an opening adjacent to the door-jamb, a magneto-mechanical-latching-assembly which operates to secure the door in a closed position, the magneto-mechanical-latching-assembly comprising:

a latch-component associated with one of the door and door-jamb, the latch-component comprising a latch, the latch comprising a latch-magnet having a latch-magnet-polar-axis, the latch being mounted relative to the latch-component to reciprocate along a substantially horizontal and linear latching-path between an extended-latching-position and a retracted-non-latching-position;

an actuator-component associated with the other of the door and door-jamb, the actuator-component comprising an actuator, the actuator comprising an actuator-magnet having an actuator-magnet-polar-axis, the actuator-magnet being mounted relative to the actuator-component to reciprocate along a substantially vertical actuator-path between a latch-magnet-attracting-position and a latch-magnet-repelling-position.

2. A combination as claimed in claim 1, wherein, when the latch is in the retracted-non-latching-position, the latch is substantially flush with the door or door-jamb.

3. A combination as claimed in claim 1, wherein the latch-magnet-polar-axis is substantially horizontal and substantially parallel to the latching-path, and the actuator-magnet-polar-axis is substantially vertical and substantially parallel to the actuator-path.

4. A combination as claimed in claim 1, wherein the latch-component is associated with the door-jamb and the actuator-component is associated with the door.

5. A combination as claimed in claim 4, wherein the substantially horizontal and linear latching-path is substantially parallel to the plane of the opening.

6. A combination as claimed in claim 5, wherein the substantially horizontal and linear latching path lies in the plane of the opening such that the latch projects into the plane of the opening when the latch is in the extended-latching-position.

7. A combination as claimed in claim 4, wherein the actuator-path is arcuate.

8. A combination as claimed in claim 7, wherein the actuator comprises a handle, and the handle is mounted for limited rotational travel relative to the actuator.

9. A combination as claimed in claim 1, wherein the latch-component is associated with the door and the actuator-component is associated with the door-jamb.

10. A combination as claimed in claim 9, wherein the actuator-path is linear.

11. A combination as claimed in claim 9, wherein the substantially horizontal and linear latching-path is substantially parallel to the plane of the door.

12. A combination as claimed in claim 9, wherein the actuator-magnet is mounted for limited vertical travel relative to the actuator in order to accommodate vertical misalignment of the door relative to the door-jamb.

13. A combination as claimed in claim 12, wherein biasing means bias the actuator-magnet towards one end of said limited vertical travel.

14. A combination as claimed in claim 1, wherein the latch-magnet has a vertical dimension (A) in a direction substantially transverse to the latching-path, and wherein the actuator-magnet has a vertical dimension (B) in a direction substantially parallel to the actuator-path, and wherein the actuator-magnet travels a vertical distance of approximately A+B along the actuator-path between the latch-magnet-attracting-position and the latch-magnet-repelling-position.

15. A combination as claimed in claim 1, wherein the latch-magnet is cylindrical with the axis of the cylinder substantially aligned with the latch-magnet-pole-axis and latching-path, and wherein the actuator-magnet is cylindrical with the axis of the cylinder substantially aligned with the actuator-magnet-pole-axis and actuator-path, and wherein the cylindrical-latch-magnet and cylindrical-actuator-magnet are substantially in opposed edge-to-edge juxtapositions when in each of the latch-magnet-attracting-position and the latch-magnet-repelling-position.

16. A combination as claimed in claim 1, wherein, when the actuator-magnet is in the latch-magnet-attracting-position, the actuator-magnet is substantially located vertically to one side of the latching-magnet and, when the actuator-magnet is in the latch-magnet-repelling-position, the actuator-magnet is substantially located vertically to the other side of the latching-magnet.
