Abstract

A sliding door with reversible hand configurations can include a plurality of mounting locations along a top and a bottom edge thereof. The plurality of mounting locations can be configured to allow the sliding door to selectively hang and operate according to multiple orientations in order to satisfy site-specific handedness requirements. In one implementation, the sliding door includes a door frame and mounting hardware for selectively mounting the sliding door to a roller track affixed near the upper portion of a doorway.

Claims (33)

1. In an architectural design environment that includes one or more modular wall systems with one or more doorways, at least one of the doorways having an upper track affixed thereto, a sliding door that can be readily reconfigured after installation in a doorway so that the sliding door can be changed from a left-handed to a right-handed opening and vice versa, the sliding door comprising:

a door frame having first and second vertical members joined at the top by a first horizontal member and joined at the bottom by a second horizontal member, the first and second vertical members and the first horizontal member together defining a top edge of the door frame which includes a plurality of mounting locations on said top edge;

a door pull connected to one of said first or second vertical members so as to define either a left-handed or right-handed door when installed in said doorway;

mounting hardware attached to said mounting locations on said top edge of the door frame in a manner that leaves the front and back sides of the door unencumbered by the mounting hardware, and said mounting hardware being removably attached to said top edge of the door frame so that if a left-handed door results when secured in the doorway, the mounting hardware can thereafter be detached from said top edge and then re-attached to said top edge of the door frame after the door frame is horizontally rotated one hundred eighty degrees, thus reconfiguring the door as a right-handed door but doing so without having to reconfigure the door pull's location on the sliding door; and

said mounting hardware comprising an assembly for slidably attaching the door frame to the upper track.

2. The sliding door recited in claim 1 , wherein the assembly for slidably attaching the door frame to the upper track comprises a roller assembly.

3. The sliding door recited in claim 2 , wherein the roller assembly comprises a bracket and one or more rollers.

4. The system as recited in claim 3 , wherein the mounting hardware further comprises one or more slow down blocks for regulating speed at which the door slides.

5. The sliding door recited in claim 1 , wherein the mounting hardware further comprises one or more slow down blocks for regulating speed at which the door slides.

6. The sliding door recited in claim 1 , wherein the mounting locations include a plurality of mounting holes for receiving the mounting hardware.

7. In an architectural design environment that includes one or more modular wall systems with one or more doorways, at least one of the doorways having an upper roller track affixed thereto, a sliding door that can be readily reconfigured after installation in a doorway so that the sliding door can be changed from a left-handed to a right-handed opening and vice versa, the sliding door comprising:

a door frame having first and second vertical members joined at the top by a first horizontal member and joined at the bottom by a second horizontal member, the first and second vertical members and the first horizontal member together defining a top edge of the door frame which includes a plurality of mounting locations on said top edge;

a door pull connected to one of said first or second vertical members so as to define either a left-handed or right-handed door when installed in said doorway;

mounting hardware comprised of at least two roller assemblies attached to said mounting locations on said top edge of the door frame in a manner that leaves the front and back sides of the door unencumbered by the roller assembly, and said roller assemblies being removably attached to said top edge of the door frame so that if a left-handed door results when secured in the doorway, the roller assemblies can thereafter be detached from said top edge and then re-attached to said top edge of the door frame after the door frame is vertically rotated one hundred eighty degrees so that the first and second vertical members and the second horizontal member together define a top edge of the door frame that includes a plurality of mounting locations on said top edge, thus reconfiguring the door as a right-handed door but doing so without having to reconfigure the door pull's location on the sliding door; and

said roller assemblies each including one or more rollers for slidably attaching the door frame to the upper roller track.

8. The sliding door recited in claim 7 , wherein each roller assembly comprises a bracket and one or more rollers.

9. The sliding door recited in claim 8 , wherein the mounting hardware further comprises one or more slow down blocks for regulating speed at which the door slides.

10. The sliding door recited in claim 9 , wherein the mounting locations include a plurality of mounting holes for receiving the mounting hardware.

11. The system as recited in claim 7 , wherein the mounting hardware further comprises one or more slow down blocks for regulating speed at which the door slides.

12. In an architectural design environment that includes one or more modular wall systems with one or more doorways, a sliding door system that can be readily reconfigured after installation in a doorway so that the sliding door can be changed from a left-handed to a right-handed opening and vice versa, the sliding door system comprising:

an upper roller track attached at a header of a doorway in a manner so that a first portion of the roller track is positioned directly over the doorway, and the remaining portion of the roller track is positioned to the left or right of the doorway depending on whether the door is to be a left-handed or right-handed door, the attachment of said roller track being removable so that if a left-handed door results when secured in the doorway, the roller track can thereafter be detached and then re-attached to the header thus reconfiguring the roller track for a right-handed door if desired;

a door comprising a door frame having first and second vertical members joined at the top by a first horizontal member and joined at the bottom by a second horizontal member, the first and second vertical members and the first horizontal member together defining a top edge of the door frame which includes a plurality of mounting locations on said top edge;

a door pull connected to one of said first or second vertical members so as to define either a left-handed or right-handed door when installed in said doorway;

mounting hardware attached to said mounting locations on said top edge of the door frame in a manner that leaves the front and back sides of the door unencumbered by the mounting hardware, and said mounting hardware being removably attached to said top edge of the door frame so that if a left-handed door results when secured in the doorway, the mounting hardware can thereafter be detached from said top edge and then re-attached to top edge of the door frame after either (1) the door frame is horizontally rotated one hundred eighty degrees, or (2) the door frame is vertically rotated one hundred eighty degrees so that the first and second vertical members and the second horizontal member together define a top edge of the door frame that includes a plurality of mounting locations on said top edge, thus reconfiguring the door in either case as a right-handed door but doing so without having to reconfigure the door pull's location on the sliding door; and

said mounting hardware comprising a roller assembly for slidably attaching the door frame to the upper roller track.

13. The sliding door system recited in claim 12 , wherein the roller track is part of a roller track assembly further comprising a trim cap and one or more brackets for affixing the roller track assembly to the header of the doorway.

14. The sliding door system recited in claim 13 , wherein the brackets of the roller track assembly are adjustable or removable.

15. The sliding door system recited in claim 12 , wherein the assembly for slidably attaching the door frame to the upper track comprises a roller assembly.

16. The sliding door recited in claim 15 , wherein the roller assembly comprises a bracket and one or more rollers.

17. The sliding door system recited in claim 16 , wherein the brackets of the roller assembly assembly are adjustable or removable.

18. The sliding door recited in claim 17 , wherein the mounting hardware further comprises one or more slow down blocks for regulating speed at which the door slides.

19. The sliding door recited in claim 12 , wherein the mounting locations include a plurality of mounting holes for receiving the mounting hardware.
