摘要： An overhead lighting fixture is hung from an overhead structure (11) using a combination including a hanger (12) secured to the overhead structure, a chain (31) having a plurality of links with the top link (32) connected to the hanger, and a lighting device (17) connected to at least one of the links, usually the bottom link (33) of the chain. An electrical supply cord is made inconspicuous or hidden. This is done as it extends down from the hanger (12) through the center of the chain (31) throughout the length of the chain and entirely within an unobstructed space within the chain to supply the lighting device (17) connected to the bottom link of the chain. Another approach is a sleeve (57) encompassing the chain (51, 52, 53, 54) and cord (56) combination. The chain is such that, when hanging from the hanger, it is flexible in primarily two vertical planes perpendicular to each other but at least moderately flexible in all vertical planes.

摘要： A system for hanging a lamp at any of a plurality of locations includes an electrical box positioned at a fixed location in a ceiling. A mounting plate has an exterior periphery with a circular central aperture there through and with holes adapted to the periphery and screws extending there through. A slip plate has a large exterior diameter greater than the diameter of the mounting plate. The slip plate is formed with a slot along the majority of one diametric extent. A small washer located between the slip plate and the mounting plate has a central aperture there through essentially equal to the diameter of the central aperture of the mounting plate and the width of the slot. A flanged cylinder has a cylindrical central extent, a central bore, a flanged interior upper end located above and in contact with the mounting plate, and a flanged exterior end in contact with the slip plate. A medallion cover has an exterior diameter greater than that of the slip plate and is positionable in contact with the ceiling.
