  • Patent number: 7837282
    Abstract: A cabinet includes side panels, a back panel, and a top panel that frictionally-attach together with non-intrusive integrally-formed connectors. The illustrated base is screw-attached, and includes openings for routing wiring within the cabinet. Brackets are adapted to support shelves in the cabinet in either a flush or inset condition, and at different heights based on which cabinet slots they engage and based on their orientation in those slots. A light-transmitting top panel and top shelf can be used to provide improved light within the cabinet. Hinge brackets on the cabinet support either a thick door with internal storage space, a proud door or an inset door. Drawers supported in the cabinet include a lock within the drawer's header for operating a vertical cabinet lock rod.

  • Patent number: 6076474
    Abstract: A freestanding support for supporting a worksurface and an overhead storage unit and the like in an open office environment includes at least three legs where each leg has a bottom portion adapted for resting on a floor, a top horizontal support adapted for receiving and supporting a worksurface on the support, and a vertical support which maintains the bottom portion and the top horizontal support in a fixed vertically spaced relationship. A stretcher extends between and is attached to an upper rear portion of the end legs thereby maintaining the two end legs in a parallel horizontally disposed relationship. The freestanding support also has at least two support posts. One support post has an intermediate portion attached to the stretcher and is positioned substantially in alignment with one of the end legs and further has a bottom portion attached to the vertical support of the end leg.

  • 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: 4960307
    Abstract: A vertical storage unit is provided for modular furniture of the type having a worksurface with an open knee space below the worksurface. The storage unit includes an open framework drawer, which is slidably mounted in a hollow cabinet for horizontal movement between a closed position in which the sides of the drawer are disposed in the cabinet, and an open position in which the sides of the drawer are disposed outside of the cabinet, and extend perpendicular beyond the worksurface. A plurality of removable, drop-in storage trays are suspended from the drawer framework in a vertically spaced apart relationship. The sides of the drawer are open to access each storage tray, such that when the drawer is in the open position, objects may be placed into and removed from the vertically arranged storage trays with a generally vertical hand motion.

  • Patent number: 4595237
    Abstract: A pedestal-type chair having a height-adjusting air spring connected between the base and seat assemblies, and a manually activated control for releasing the air spring. The control includes a small manually engageable activating lever pivotally supported interiorly of the seat assembly adjacent one side thereof and positioned so as to project slightly downwardly a small extent through the lower seat shell. This lever is connected to one end of an elongated flexible cable which extends interiorly of the seat assembly and has its other end connected to a force transfer lever positioned within the central interior of the seat assembly. This latter lever activates the valve-release member associated with the air spring.
