  • Patent number: 5728970
    Abstract: The invention is directed to a modular electrical system attachable to a modular office partition, including an electrical distribution assembly with at least two projections extending from one side thereof. At least two projection receiving members are associated with the partition, and engageable with a respective projection. At least one resilient retainer device is biased to a retaining position for securably and releasably maintaining at least one of the projections in engagement with a respective receiving member. The resilient retainer device is also movable to a disengaging position allowing the at least one projection to be disengaged from the respective receiving member.

  • Patent number: 5713757
    Abstract: An assembly for supplying power to a system of modular wall panels may include a housing, a lid, and a sleeve positionable on a conduit and disposed between the lid and housing. The sleeve is configured to have a predetermined shape that cooperates with structure on either the lid, the housing, or both to fix the conduit in a plurality of different orientations or positions with respect to the housing and lid. The sleeve may include positioning means, such as a key, and the housing may be configured to include an opening in which the positioning means is selectively positionable in a first orientation whereby the conduit assumes a first position with respect to the housing and a second orientation whereby the conduit assumes a second position with respect to the housing that is different than the first position. The housing may include a second opening in which the positioning means is disposed when the conduit assumes the second position.

  • Patent number: 5584714
    Abstract: The invention is directed to a modular electrical receptacle including a housing and a faceplate. The faceplate is integral with or attached to the housing, and has at least two parallel blade openings and at least two T-slot blade openings. The parallel blade openings are disposed along a common longitudinal axis, and each T-slot blade opening is associated with a respective parallel blade opening. At least one plug-in electrical connector is attached to the housing and/or the faceplate. A conductor member defines at least two T-slot blade sockets, with each T-slot blade socket associated with a respective one of the T-slot blade openings. The conductor member interconnects at least one connector with each T-slot blade socket. The conductor member can be of monolithic or two-piece construction.
