  • Patent number: 6253826
    Abstract: The folding door for an office cubicle provides an inexpensive, universally applicable mechanism for selectively opening and closing the entryway of an office cubicle. The folding door comprises an accordion-style folding door panel (1) fabricated from a sheet of lightweight, semi-rigid material with a plurality of specifically aligned magnetic fasteners (30) attached to both surfaces. The folding door panel (1) is pivotally attached to a partition jamb (14) adjacent the entryway by a vertical hinge (8) attached along one panel edge (6). The opposite panel edge (13) includes a dual latching handle member (18) which is used to selectively secure the door when unfolded in the closed entryway position and to retain the door out of the entryway when folded in the open entryway position.
