  • Publication number: 20010013209
    Abstract: A knock-down portable partition includes a rigid panel frame having a central portion. The partition includes at least one cover panel covering at least a portion of the central portion of the rigid panel frame. Connectors detachably mount the cover panel on the panel frame to facilitate assembly and removal of the cover panel on the panel frame. The rigid panel frame includes at least two vertical posts having an upper end, a lower end, and opposite side faces. The opposite faces have at least two beam connection ports thereon positioned adjacent the upper and lower ends of the associated one of the posts. The panel frame also includes upper and lower beams extending generally horizontally between the vertical posts adjacent the upper and lower ends thereof, and interconnecting the vertical posts adjacent the connection ports. The panel frame includes quick-disconnect connectors such as movable lock members positioned on one of the posts and the beams adjacent the connection ports.

  • Patent number: 6272803
    Abstract: A partition system includes adjacent partitions that have aligned top frame members with abutting and horizontally aligned cantilevered end sections. An in-line connector system includes a flat top connector and a U-shaped bottom connector that mateably span between the cantilevered end sections and that engage top and bottom surfaces, respectively, on the top frame members. Specifically, the top connector fits into a cavity in a top of the top frame member. The bottom connector includes a bottom wall and opposing sidewalls that matingly receive and engage bottom and side surfaces of the cantilevered end sections. The connectors combine with a beam-like strength that holds the cantilevered end sections in a particularly stable in-line condition.

  • Patent number: 6009675
    Abstract: A knock-down portable partition system has cover panels supported on a post and beam framework designed for quick and easy on-site manual assembly without tools. The framework includes at least two vertical posts with at least two beam connection ports on opposite side faces adjacent upper and lower portions of the posts. Each beam connection port has a window through the side face of the post, and first and second horizontally aligned fastener apertures in front and rear faces of the post adjacent opposite sides of the window. At least two structural beams rigidly, yet detachably interconnect the vertical posts at the upper and lower portions thereof. Each end of each of the structural beams is shaped for close reception in an associated post window, and includes a vertically oriented, transverse notch through a lower portion of the beam in which a lower edge of the post window is closely received to longitudinally lock each beam in its associated post.

  • Patent number: 5252086
    Abstract: A power distribution system for office furniture includes a powerway having a power block with power block conductors therein. A outlet block is supported on the powerway and includes outlets for the office furniture. The outlets are connected to different conductors in the powerway by a jumper. The powerway may include at least three first connectors on one end and at least one second connector on the other end. The first and second connectors interconnect thereby facilitating connection with other identical powerways. According to one aspect, one component includes a projection and another component includes a recess which facilitate connection of these components using a substantially flat implement.

  • Patent number: 5220871
    Abstract: A freestanding modular furniture arrangement is provided to create workstations in open office plans, and other similar applications. Each furniture unit includes a worksurface with capped cutouts in the rear corners to mount overhead cabinets, privacy screens, and other furniture accessories. A mounting rail extends continuously along the rearward edge of each worksurface, and is capable of removably supporting therein a plurality of different amenities, such as bookshelves, CRT stands, fans, task lamps, etc., so as to permit a worker to personalize his or her own workstation. A removable stanchion permits certain convertible amenities to be supported either freestanding on the worksurface, or along the rear of the worksurface on the mounting rail. An L-shaped intermediate leg is available to support the worksurface in a cantilevered fashion to facilitate unfettered task chair movement along the forward edge of the worksurface.

  • Patent number: 4514106
    Abstract: There is disclosed a table upright connector member or T-joint useful for joining tubular members comprising a tubular cross-member and a tubular stem member and to a process for effecting the same. The T-joint comprises a tubular segment complementary with the tubular cross-member and rigidly secured to the end of the tubular stem member and having a diameter slightly less than that of the tubular cross-member. The tubular segment is drawn up tight against the tubular cross-member by draw bolts to give a rigid structure.
