The tripod stand (1) supports a tool or device (4) as required on the end of a sprung arm (3) which may be moved about a vertical axis. The arm pivots (6) about an overhead (7) support, in turn held in place by an approximately vertical rod (9) with hooked upper end. The rod is supported either on a castor-mounted base plate, a wall or ceiling fixture. |
