The present invention relates to a tripod with adjustable support surface for supporting various objects, wherein the stand comprises a central support provided with pivot pins for telescopic legs adapted to pivot in radial planes. According to the invention, a selection ring is mounted to rotate about the vertical axis of the support, immobilised in axial translation and limited in amplitude of rotation in order to be able to occupy at least two angular positions and this ring bears at least two sets of three stop members cooperating with end stops of the legs, these sets being offset angularly in register with the positions of the ring and defining respectively at least two different inclinations of these legs. This tripod may be used for supporting photographic, cinematographic, or video shot taking apparatus, projection apparatus, geodesic measuring instruments, antennas for emitting or receiving radioelectric waves or the like. |
