ABSTRACT:
Each one of a pair of swing units, for mounting the swing arm assemblies of a swing arm lamp, is formed as a relatively short substantially tubular member having a tubular mounting end of reduced outside diameter and that is provided with a circumferential groove. The reduced end of each swing unit is received by a respective mounting seat of a vertical swing bracket which mounts both swing units for rotation about a pair of predetermined axis of rotation that are spaced and parallel one to the other. A pair of threaded bolt like members are carried by the swing bracket so that an end of each threaded member can be moved from a position wherein the end projects into its respective groove, to prevent unseating of the swing unit from the bracket, but not so as to prevent rotation thereon; to a position wherein said ends are removed from the respective grooves so that the swing units can be removed from the bracket. The swing units each receive an end of a tubular swing arm of a swing arm assembly along lines which are either perpendicular to said predetermined axis of rotation, or co-axial therewith.
