Patent number: 7461484Abstract: 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.Type: GrantFiled: February 14, 2003Date of Patent: December 9, 2008Assignee: Steelcase Inc.Inventors: David J.

Publication number: 20020029529Abstract: 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.Type: ApplicationFiled: April 5, 2001Publication date: March 14, 2002Inventors: Michael L.
