Abstract
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. The internal cavity and demountable front-accessory panel of the stanchion may receive electrical service wiring comprising a conventional cable and connector shell rigidly mounted on a support bracket having a spring clip, enabling an electrical receptacle to be quickly and releasably secured to the mounting bracket spring clip while simultaneously mating electrical contacts on the receptacle with electrical contacts provided in the cable connector shell.
