Abstract
An adjustable arm structure capable of being used to support comparatively heavy lamps, books and the like can be constructed so as to use two adjustable arm assemblies. Each of these assemblies uses two parallel links, one of which is attached to a sector plate. The sector plates are clamped together in the structure in a connecting joint at a location remote from where the links are pivotally connected to or in the connecting joint.
