  • Patent number: 6394553
    Abstract: An armrest assembly for a chair which can be adjusted in multiple aspects with the use of single actuating mechanism. The adjustment aspects of the preferred embodiment include a vertical adjustment with respect to the chair and a horizontal rotational adjustment. Such an armrest assembly can include an armrest base securable to a chair and having a tubular portion, a hollow armrest support slideably and rotationally disposed about the tubular portion and an armpad attached to the top of the hollow armrest support. A handle to disengage the actuating mechanism is provided.

  • Patent number: 6086034
    Abstract: A mouse pad support is mounted on a keyboard support that has a keyboard support arm attachable to a fixed structure such as the underside of a desk top, and a tiltable keyboard support platform thereon. A mouse pad support arm is coupled to the keyboard support arm via a rotational swivel fitting with a vertical axis for moving the mouse pad arm and mouse pad support table to any position around the keyboard in a circular arc in a horizontal plane. The height of the swivel fitting is adjustably fixed over a range. The mouse pad arm is kept in a horizontal plane because its rotational coupling to the keyboard support arm is made at an angularly fixed part on the keyboard support arm, such as on a parallelogram linkage associated with setting the elevation of the keyboard platform. The keyboard platform tilts relative to the angularly fixed part, whereby mouse position is independent of keyboard platform tilt.

  • Patent number: 6029587
    Abstract: An offset cantilevered support leg for a height adjustable desk which resists lateral forces is provided. Each support leg is connected to the underside of the desk top at the lateral ends thereof by an L-shaped bracket. A primary support arm provides the cantilevered support for the desk top while a secondary support arm, angularly offset from and generally oriented perpendicularly with respect to the primary support arm, provides support against lateral forces directed against the legs. By orienting each of the respective support arms of the L-shaped bracket with the rear corners of the work surface, the legs provide adequate support against vertical and horizontal loading while maximizing the available space underneath the desk, and thus eliminating the need for a horizontal stretcher between the cantilevered support leg.

  • Patent number: 5906420
    Abstract: An office furniture system of free standing furniture elements which can be linked to each other comprises a modular desk unit and a modular storage unit. The modular storage unit occupies the same floor footprint as a rectangular desk unit. The separate storage unit enhances the storage capacity of an office layout since the mounting of drawers and shelves are not limited by the desk unit configuration. The storage unit has compatible lay-in wiring trays, accepts compatible modular power components and accepts the same privacy partition panels and other accessories as are mounted to the desk units. When the desk unit and the storage unit are linked into an integrated office design, a continuous pathway is provided for the electrical, communication and data wiring required for the office system. Power cables are physically separated from the data and communication wires.

  • Patent number: 5881979
    Abstract: A telescoping leveler can include a housing having one end securable to a support column of an article of furniture and a threaded bore provided in an opposite end, a cylindrical intermediate member threaded on both an outside surface and an inside surface with the threaded outside surface threaded into the threaded bore of the housing, and a leveling glide having an upper threaded shaft portion that can be threaded into the threaded inside surface of the cylindrical intermediate member. The leveling glide can also have a lower foot portion. Additionally, a plurality of telescoping cylindrical intermediate members can be provided between the housing and the leveling glide. Furthermore, a stop means can be provided to prevent the threaded shaft and the intermediate members from being fully removed out of the threaded bore and threaded inside surfaces.
