  • Patent number: 8113607
    Abstract: A storage assembly comprises a storage unit having a plurality of walls that cooperate to form an interior space and an opening in communication with the interior space, a first track having a first width and a second width along the length thereof, and a second track having a first width and a second width along the length thereof, wherein the second widths are different than the first widths, respectively. The storage assembly comprises a first door assembly slidably disposed along the first and second tracks via first guide members each having width less than the first width of the first and second tracks, and a second door assembly slidably disposed along the first and second tracks, and having a pair of second guide members each having a width that is greater than the first width of the first and second tracks and less than the second width of the first and second tracks.

  • Patent number: 7461484
    Abstract: A partition system includes an internally-open partition frame having permanent and removable frame members forming multiple vertical and horizontal wireways, with both lay-in and feed-through wire routing. Utility support brackets are attachable for good wire management. The partition frame supports a wide variety of customizable and functional surface components, including a markerboard wall surface, a slatwall, a colored/covered wall surface, a wall surface including utility outlets, a transparent window. The partition frame includes continuous horizontal and vertical rows of slots that flexibly and adjustably support furniture accessories, such as a worksurface, at selected heights and locations along the partition system. Covers are provided that maintain a very high-quality appearance with uniform lines and gaps. Some covers include adjustable edge-mounted light seals for eliminating light leaks and unsightly areas.

  • Publication number: 20020029529
    Abstract: A partition includes at least two vertical posts with upper and lower beams having opposite ends thereof interconnecting the vertical posts to define when in an assembled condition, a rigid panel frame having a substantially open interior. The panel frame defines a vertical dimension. At least one cover panel is configured to enclose at least a portion of the open interior of the panel frame, and is removably mounted on the panel frame to readily access the open interior thereof. The cover panel defines an interior surface and a center portion spaced-apart from the posts. A cover panel brace is connected with the upper beam, and has an outer surface abutting the interior surface of the cover panel to support the cover panel adjacent the center portion to prevent flexing of the cover panel. The cover panel brace is longitudinally extensible to accommodate variations of the vertical dimension between the upper and lower beams.
