  • Patent number: 6336414
    Abstract: A table construction includes a base having a pair of legs secured together by a transverse beam, and a tabletop pivoted to a top of the legs for movement between a horizontal use position and a vertical storage position. A pair of support arms are pivoted to the top of the legs for selectively holding the tabletop in the horizontal use position. The support arms are spring-biased and pivoted at an angle so that they counterbalance a weight of the tabletop during its pivotal movement. Ganging connectors on opposite ends of the tabletop automatically interconnect adjacent tables upon pushing adjacent tables together. The legs each include first and second castings that bolt together and that are arranged to matably nest when tables are moved together for storage. A utility raceway structure attached to the base includes a frame that defines upper and lower chambers and further includes upper and lower lockable doors providing separate access to the upper and lower chambers, respectively.

  • Patent number: 6305816
    Abstract: A linear ambient lighting system is adapted for on-site fabrication in open building plans and the like. The lighting system includes a plurality of elongated lighting elements having electrical power sockets at the opposite ends thereof to physically support the lighting elements and electrically connect the same with electrical connectors to supply electrical power to the lighting elements. Suspended fixture supports are connected with and support the electrical power sockets and are configured to be spaced longitudinally along the length of the associated lighting fixture. Hangers are provided with first ends connected with an overhead support portion of an associated building, and second ends connected with and supporting the fixture supports. An elongated housing having an uninterrupted one-piece construction is formed on-site from strip stock to a selected length that extends continuously along the entire length of the associated lighting fixture.
