Abstract
Abstract A knock-down floor lamp that is shipped prewired and unassembled in a package, and then can be readily assembled by the ultimate consumer with simple tools and without twisting of the electrical prewiring. First and second elongated tubular turnings are provided, the first turning having a socket formed at a first end thereof, and the second turning being releasably connectable to a lamp base at a first end thereof. A tray is disposed between the turnings, and they are connected together, sandwiching the tray therebetween, with structure that does not require rotational movement of one turning with respect to the other. Preferably a first plate having three screw threaded rods extending therefrom is attached to the first turning and passes through bores in the tray and in a second plate attached to the second turning, nuts being disposed on the end of the threaded rods to hold the turnings in place. An electrical cord having a length significantly longer than the sum of the lengths of the turnings and a cord passageway in the base, is connected to the socket at a first end thereof and has a plug at the second end thereof, and extends through the turnings, tray and base. In the unassembled position, a layering is provided within a carton, the layering including the turnings, a cardboard sheet, the tray, another cardboard sheet, and the base, with thin film plastic holding all of the components together. A shade may be packaged in the same carton.
