A stand for mounting objects such as optical equipment, comprises an upright (10) with an object support arm (15) movable vertically and laterally relative to the upright (10). A guide part (13) surrounds the upright (10) and is movable along the latter, and the support arm (15) moves horizontally on the part (13) and comprises two parallel parts (42, 43) which enclose the guide part (13) and are flanged inwardly to run on rollers (33-36) on the guide part (13). The guide part (13) also runs on rollers (20-23) on the upright (10) and the guide part (13) is provided with clamps (28-30, 49-52) which are operable to prevent the vertical movement of the guide part (13) on the upright (10) and the lateral movement of the arm (15) on the guide part (13). The support arm (15) has a handle 45 at one end, object mounting means (45, 17-19) at the other end and resilient buffers at each end to limit the lateral movement. A rope (26) is attached to the support arm (15) passes over a pulley (27) on top of the upright (10) and supports a balance weight inside the hollow upright. <IMAGE> |
