Abstract

A sliding door panel and assembly is described, such that when in the door panel is in an open arrangement there is a functional cooperation or coupling between at least a first unit and a second unit of the assembly. The second unit is generally affixed to the sliding door and the first unit is fixedly mounted with a sliding door guide system or to a header/footer or frame. A third unit may be included with the assembly such that when the sliding door panel is positioned in the open arrangement, the third unit limits engagement between the first and second units. In addition, the third unit is positioned to limit linear movement of a slideable portion of the first unit thereby preventing damage.

First claim

What is claimed is:

1. An assembly for holding a sliding door panel in an open position, the assembly comprising:
a first base having a sliding component extendible and retractable relative to the first base, one end of the sliding component supporting a first pivoting element secured to the one end, and pivots about said one end, during the operation of the assembly the first base configured to securely fasten, and remain stationary relative to the sliding door during operation; and
a second base having a second pivoting element extending from the second base and pivoting with respect to the second base, the second base further configured to secure to the sliding door panel in a fixed position such that the second base is moveable with sliding action of the sliding door, the second pivoting element and the first pivoting element being aligned along a common axis to facilitate coupling of the first pivoting element of the first base to the second pivoting element of the second base when the sliding door panel is in a fully opened position,
the sliding component of the first base extending and retracting relative to the first based along the common axis in response to movement of the sliding door panel from a closed position to the fully opened position.

2. The system of claim 1 further comprising a stop positioned along the common trajectory to contact a leading end of the sliding door panel when the sliding door panel is in the fully opened position and prevent direct contact between the first base and the first pivoting element.

3. The system of claim 1 , further comprising a door stop positioned to prevent further movement of the leading end of the sliding door panel after coupling of the first and second pivoting elements.

4. The system of claim 1 , wherein the first and second pivoting elements are magnetically attracted to each other.

5. The system of claim 1 , wherein the first base comprises at least one opening to slideably receive a cylindrical piston movable therein, the first pivoting element disposed on an end of the cylindrical piston.

6. The system of claim 1 , wherein the first pivoting element is a ceramic disc magnet.

7. The system of claim 1 , wherein the second base comprises a slot to enable positional adjustment of the second pivoting element relative to the second base.

8. The system of claim 1 , wherein the sliding component is mounted in an opening on the first base and comprises a cylindrical cross section.

9. A system for holding a door panel when in an open position, the system comprising:
a first base disposed in a fixed position adjacent to the door panel along a common path of the door panel, and having a sliding component extendible and retractable relative to the first base for moving relative to the first base, the sliding component comprising a first coupling element disposed on one end that pivots about the one end during the operation of the assembly;
a second base having a second coupling element secured thereto, the second base fixed to the door panel, and moving with the door panel along the common path, the second coupling element extending from the second base and positioned to be releasably cooperative with the first coupling element of the first base when the door panel is in a fully opened position, the sliding component of the first base positioned along a common axis with the second coupling element of the second base with respect to the common path; and
a stop member positioned independent from the first base and the second base for contacting a leading edge of the door panel when the first and second coupling elements are secured together, such that the stop member prevents contact between the first base and the first coupling element.

10. The system of claim 9 , wherein the first and second coupling elements are pivoting plates to facilitate flush engagement therebetween.

11. The system of claim 9 , wherein the first base further comprises a bracket for supporting the sliding component for sliding movement.

12. The system of claim 9 , wherein the second coupling element is magnetic.

13. The system of claim 9 , wherein the first and second coupling elements are magnetically attracted to each other.

14. The system of claim 9 , wherein the second base comprises an adjustment slot to enable positional adjustment of the second coupling element relative to the second base.

15. The system of claim 9 , wherein the first coupling element comprises a ceramic disc magnet.

16. A method for holding a door panel, the method comprising:
providing a door panel having a leading edge and slideable along a common path;
positioning in a fixed location a first base adjacent the door panel and along the common path, the first base comprising a sliding component therein, the sliding component extendible and retractable relative to the first base, and in response to movement of the door panel, the sliding component further configured with a coupling element on one end that pivots about the one end during the operation of the assembly;
fixing a second base to the door panel in a position for movement with the door panel along the common path, the second base comprising a coupling element for releasable engagement with the first base coupling element when the door panel is in the open position; and
positioning a stop member independent from the first base and the second base for contacting a portion of the leading edge of the door panel when the first base and the second base are coupled along the common path, thereby preventing contact between the first base coupling element and the first base.

17. The method of claim 16 , wherein the first base is further configured with a bracket portion for supporting the sliding component.

18. The method of claim 16 , wherein the first unit and second unit coupling elements are magnetically attracted to each other.

19. The method of claim 16 , further comprising providing first base and second base pivoting plates as coupling elements to facilitate flush engagement therebetween.

20. The method of claim 16 , further comprising providing an adjustment slot on the second base to enable positional adjustment of the coupling element of the second-unit relative to the second base.

21. The assembly of claim 1 , wherein the sliding component further comprises a retaining ring at or near an end opposing the one end of the sliding component supporting the first pivoting element for preventing the sliding component from being released from the first base.

22. The assembly of claim 1 , wherein pivoting by one or more of the first pivoting element and second pivoting element is provided by a slip joint.

23. The assembly of claim 1 , wherein pivoting by one or more of the first pivoting element and second pivoting element is provided by a non-rigid securement of the one or more of the first and second pivoting element with respect to the first and second base, such that a gap remains around the one or more of the first and second pivoting element after the non-rigid securement.
