  • Patent number: 6209266
    Abstract: A workspace display comprises a sidewall partition defining a workspace with a portal opening and a door partition to selectively close the portal. A first display screen is disposed on the interior side of the door partition for individual viewing from inside the workspace. A second display screen is disposed exterior of the sidewall partition and positioned a spaced apart distance in general alignment therewith, without substantial interference with user ingress and egress through the portal opening. A video device is positioned overhead in optical communication with the first display screen when the door partition is in its fully closed position to support individual activities. The video device is in optical communication through the portal opening with the second display screen when the door partition is in its fully open position to support group activities. An image on the second display screen can be viewed on either the interior or exterior screen surfaces.

  • Patent number: 6189270
    Abstract: A partition wall system provides for lay-in of cables. The system includes a plurality of interconnected panel sections and a plurality of covering skins. Each panel section has a base surface and a protrusion extending from the base surface. At least one of the covering skins is attached to each of the panel sections, forming a passage between the covering skin and the base surface of the panel section allowing the cables to travel between interconnected panel sections and through each panel section, in both horizontal and vertical directions. Interconnected panel sections may include first and second sheets of material, each sheet of material providing a base surface with a plurality of protrusions extending therefrom, wherein the first sheet of material is attached to the second sheet of material so that the base surface of the first sheet of material is substantially parallel to the base surface of the second sheet of material.

  • Patent number: 6179384
    Abstract: A chair includes a back frame and a flexible back support operably supported on the back frame. The flexible back support includes a flexible lumbar region and a flanged bracket pivotally connected to the back frame at a back support pivot. A force adjusting device is attached to the back frame at the back support pivot for adjusting a torsional spring-generated biasing force on the flanged bracket relative to the back frame. The force adjusting device includes a housing, a base attached to the housing, a spring operably mounted in the housing, and a gear arrangement operably connected to a cup-shaped handle to biasingly adjust a position of the spring with mechanical advantage to adjust a tension of the spring. A clutch is operably attached between the gear arrangement and the handle.

  • Patent number: 6176550
    Abstract: An armrest construction for chairs includes an armrest support having a lower end constructed for attachment to a chair, an upper end, and a mounting block attached to the upper end. A pivot block is pivoted to the mounting block at a main pivot, the pivot block having an upwardly-extending follower. First and second gears are each pivoted to the pivot block, the gears having intermeshing teeth at an inner end such that rotation of the first gear causes the second gear to simultaneously rotate in an opposite direction, the first and second gears further having outer ends. A support plate having pivot/slide members engages the outer ends of the first and second gears, and further has a guide operably engaging the follower to guide lateral movement of the support plate along a predetermined path.

  • Patent number: 6173545
    Abstract: A partition system includes a first partition having a face and a horizontal row of slots accessible through the face, and a second partition having an abutting end adapted to be positioned adjacent the face. The first partition includes a frame and covers on the frame that define a horizontally extending gap for accessing the slots. A connector for interconnecting the abutting end to the face includes a one-piece U-shaped clip having a pair of legs forming a first end with opposing hooks configured to securely horizontally engage the slots in the face, and having an intermediate section forming a second end configured to securely engage the abutting end. The intermediate section is resilient such that the legs can be flexed together to an install position for insertion into a selected slot and can be flexed apart to a retaining position where the hooks are positioned to securely engage the selected slot in the first partition.
