  • Patent number: 6158179
    Abstract: A wall structure for dividing building space includes several different freestanding base panels such as an internally open partition panel, a sound-deadening partition panel, a glass-supporting partition panel, and a doorway-supporting partition panel, and further includes an overhead system comprising a structural expressway construction, a transom subframe, covers for the subframe, and a glass module attachable to the subframe. The structural expressway construction has a torque box bracket for moving support from an inboard location spaced from the vertical side edge of the base panels to the vertical side edge. The transom subframe mounts atop the different base panels, and telescopingly extends into mating engagement with a ceiling channel.

  • Patent number: 6141925
    Abstract: A movable transparent panel for reconfigurable office partitions and the like is adapted for floor-to-ceiling applications which include a floor track shaped to be supported on a floor surface, and a ceiling track shaped to be supported on a ceiling surface. A panel frame is supported in a normally vertical orientation between the floor track and the ceiling track. The panel frame has vertically spaced-apart upper and lower horizontal members with a pair of vertical side members interconnecting the upper and lower horizontal members and extending therebetween to define a generally quadrilateral opening. The upper horizontal member is operably connected to the ceiling track, and the lower horizontal member is operably connected with the floor track. A substantially transparent sheet is removably connected to the frame and extends across at least the portion of the opening.

  • 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.
