  • Patent number: 5765797
    Abstract: An articulated support for a display including a base having a fore-to-aft slide assembly located proximate a rear portion of the base, a primary support for supporting the display, and having a pivot glide assembly depending from a rear portion of the primary support received within the fore-to-aft slide assembly for simultaneous translation and rotation therein, and a linkage assembly pivotally interconnecting the primary support to a forward portion of the base such that when the forward portion of the primary support is moved vertically, the primary support is simultaneously rotated and translated at a predetermined, synchronous rate with respect to the vertical translation of the forward portion of the primary support to automatically adjust the display as the user's viewing position changes vertically.

  • Patent number: 5636578
    Abstract: A table includes a tabletop and a pair of opposing folding leg assemblies. Each folding leg assembly includes a base plate secured to the tabletop. A folding leg is pivotally connected to the base plate by a linkage arrangement that includes a first link pivotally connecting the folding leg to the base to define first and second axes of rotation and a second link pivotally connecting the folding leg to the base to define third and fourth axes of rotation. The second link includes a transverse section, and a latch is secured to the base plate for releasably engaging the transverse section when the folding leg is in the extended position. The first link also includes a transverse section or recess for engaging the latch to hold the folding leg in the folded position.

  • Patent number: 5568775
    Abstract: An articulating table connection or arrangement includes an in-fill piece occupying a gap between spaced tables and remaining in abutment with the tables as the tables are relatively aligned at any angle around a center defined by a curved arc segment at an edge of at least one of the table tops. At least one of the tables when viewed as a whole in plan is non-circular and preferably C-shaped or kidney shaped, but has a portion of an edge that defines a circularly curved arc segment along a limited distance. The in-fill piece has a complementary shaped edge abutting the arc segment. The in-fill piece carries brackets which stabilize the in-fill piece and tables in such relative positions that the upper surfaces of the tables and in-fill piece occupy a common plane. The brackets further couple the tables and in-fill piece together for relative movement at least so that the complementary edge of the in-fill piece is pivotable relative to the arc segment of the table.

  • Patent number: 5562051
    Abstract: A table includes a tabletop and a pair of opposing folding leg assemblies. Each folding leg assembly includes a base plate secured to the tabletop. A folding leg is pivotally connected to the base plate by a linkage arrangement that includes first links pivotally connecting the folding leg to the base to define first and second axes of rotation and a U-shaped second link pivotally connecting the folding leg to the base to define third and fourth axes of rotation. The second link further includes a transverse section, and a latch is secured to the base plate for releasably engaging the transverse section when the folding leg is in the extended position. The first, second, third, and fourth axes are spaced from each other and located so that the folding legs fold flat against the tabletop when in the folded position, but so that the axes do not move "on center" or "over center" and cause the legs to lock up when in the folded position.

  • Patent number: 5289782
    Abstract: An adjustable height table having a top that can be vertically adjusted to various heights by a pair of telescoping legs and a counterbalance weight mechanism which includes a weight box and weights that can be easily added or removed by the user depending on the weight carried by the table top. A locking mechanism including a spring-urged threaded half nut and a stationary threaded rod enables the table top to be locked in place once a desired height is achieved.

  • Patent number: 5226705
    Abstract: A fully enclosed structural support stanchion for furniture is provided, having an internal cavity which may receive standard modular office furniture electrical service cabling, and which is provided with a demountable front accessory panel to which plural electrical or electronic accessories may be mounted such that a portion of the accessory extends into the stanchion and releasably connects to one end of the standard modular furniture electrical service cabling. The stanchion is constructed with rigid materials so that it can act as a support for an overhead bookshelf or other storage facility, and the stanchion is further provided with a large internal storage cavity into which small office supplies or other articles may be placed and stored behind a hinged, selectively closable door. The stanchion further includes an elongated bracket support which may receive standard shelf brackets, permitting the stanchion to act as a cantilever support for structures such as shelves secured to the shelf brackets.

  • Patent number: 5020752
    Abstract: An adjustable pedestal comprises a tubular base, a tubular collar telescopically, slidably engaging the exterior of the base, a guide tube interior to the base, an extension spring mechanism positioned within the guide tube for biasing the pedestal in an extended position, and a locking mechanism for locking the pedestal in the desired position. The base, collar, and guide tube are coaxial. The collar is movable between an extended and a retracted position with respect to the base, and the guide tube is movable with the collar between an extended and a retracted position with respect to the base. The extension spring mechanism comprises a pair of parallel, spaced-apart extension springs, the axes of which are parallel to the axes of the base, collar, and guide tube and normally biases the collar and the guide tube in their extended positions. The extension springs are in a retracted condition. Thus, when force is exerted on the top of the guide tube, the extension springs assume an extended condition.
