Abstract

A flush-mounted multi-service floor outlet, to provide electrical power and multiple voice/data access jack outlets has a unitary, longitudinally compartmented cylindrical metal housing for location in penetrating relation through a cement floor. The power, voice and data connections are normally routed through the ceiling space of the underlying room and are sealed within conduits that are threaded into a base portion of the metal housing. The outlet housing is dimensioned to achieve a nominal fit within a standard sized hole drilled through the concrete floor, and to provide a minimal diametrical clearance with the drilled hole as to render the installation effectively fireproof. A threaded retaining nut may be used to secure the outlet housing in place. Internal compartment partitions isolate the respective ones of power, voice and data conductors and terminations, the partitions being withdrawable so as to provide effective access and facilitate installation and servicing of the respective services. The slim, substantially planar top face of the outlet fits effectively flush with the usual carpet floor covering.

Claims7

Dependent claims

A fire-resistant multi-service outlet for mounting in a bore of predetermined standard size drilled through an existing concrete floor, to minimize structural damage to the floor, comprising a totally enclosed cylindrical housing having a shallow cover portion in substantial closing relation with the top of the cylindrical housing;

said cylindrical housing having an outer diametrical dimension nominally less than said predetermined standard drilled bore;
locating means including an upper, radially projecting flange, and a rotatable nut threadedly attached to a lower end portion of said housing, and rotatable thereabouts, to engage an adjacent portion of said concrete floor in sandwiched relation between said upper flange and said nut, to secure said housing in substantially sealed relation with said floor;
at least two accesses in the lower portion of the cylindrical housing, to receive an electrical conduit and a further service conduit in attached relation thereto;
an electrical outlet and at least one further service outlet secured in substantially flush-mounted relation with said cover portion, said housing fitting in secured, substantially sealing relation within said bore to maintain a fire separation and maintaining said outlets substantially level with said floor.
