ABSTRACT:
The swing unit, for mounting the swing arm assembly 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 the swing unit is received by the mounting seat of a support unit which mounts same for rotation about a predetermined axis of rotation. A threaded bolt like member is carried by the support unit so that an end of the threaded member can be moved from a position with its end projecting into the groove, to prevent unseating of the swing unit from the support, but not so as to prevent rotation thereon; to a position with its end removed from the groove so that the swing unit can be removed from the support. The swing unit receives an end of a tubular swing arm of the swing arm assembly along a line which is either perpendicular to said predetermined axis of rotation or co-axial therewith. The support for the swing unit is either plate like for mounting to a wall, or substantially tubular to facilitate mounting the swing arm to a base mounted support post for a table or floor lamp. The support mounts either a single swing unit for a single swing arm assembly; or a pair of co-axial swing units for a pair of co-planar swing arms of either straight or bowed configuration.
