  • Patent number: 5899025
    Abstract: An integrated prefabricated furniture system is provided for fitting-out a building room of the type having a generally open plan interior and having at least one utility source. The furniture system includes a plurality of horizontal beam segments interconnected in an end-to-end fashion to form a rigid overhead framework configured to be positioned above the floor surface. A plurality of overhead support columns each have an upper portion rigidly connected with the overhead framework, and a lower portion shaped to support the overhead framework on a floor in a freestanding fashion at a predetermined elevation above average user height. Each of the overhead support columns includes an interior support structure in a generally X-shaped plan-form defining vertical raceways between adjacent legs of the cross-section.

  • Patent number: 5826385
    Abstract: A partition construction for subdividing a building space includes a partition frame having an open interior and defining a front side, a first cover covering a section of the partition frame with apertures for providing utility access, and a second cover slidably supported on the partition frame proximate the first cover. The second cover is slidable parallel the front side between a closed position covering the open interior and an open position providing access to utilities in the open interior. The second cover is semi-flexible so that it can be simultaneously slid along the partition frame and flexed away from the partition frame to a disengaged/removed position, thus allowing it to be removed even when the second cover is "trapped" on the partition frame by a furniture component attached to or positioned in front of the partition frame.
