Abstract

The support for a load, particularly a lamp, includes a standard spring-loaded arm (3) which is pivotable about a vertical axis and vertically adjustable for holding and positioning the load (4). The spring-loaded arm (3) is connected with other parts (9,8) of the support by engagement of an upwardly directed pin-shaped connector element (5) in a downwardly directed connector pipe or socket section (6), so that the spring-loaded arm (3) is suspended from the other parts. The spring-loaded arm (3) with the upwardly directed pin-shaped connector element (5) has universal applicability in a variety of supports including ceiling or wall supports, which have a cantilever arm (8) from which the connector pipe section (6) extends downwardly, and floor or table supports, which have a stand (14,22) and a support tube (9) extending upward from the stand and having a curved section (10) to which the connector pipe section (6) is attached.
