[57] ABSTRACT
A swivel arm featuring a cantilever capable of swiveling about a vertical pillar. Said pillar can be fixed at a desk by means of a locating plate and a clamping arm. A board with straight guides holding a carrying frame, the latter being designed as a cage and being vertically movable, is mounted at the free end of the cantilever and can be pivoted about a vertical pin. Said carrying frame serves to accommodate the appliance to be held by the swivel arm. The cantilever consists of a rectangular hollow section and of a supporting plate capable of being extended from it in a telescope-type manner. Guiding of the supporting plate in the rectangular hollow section is effected via upper rails, extension rails and further upper rails, similarly to a drawer.
