Abstract
A supporting arm for a projection apparatus has first and second arm sections and an articulation apparatus therebetween for interconnecting the arm sections. The projection apparatus can be fastened on a free end of the second arm section. The articulation apparatus permits the second arm section to rotate relative to the first arm section between a first position, in which the longitudinal axes of the arm sections run substantially mutually parallel, and a second position, in which the longitudinal axes of the arm sections run substantially mutually at right angles. A spring apparatus is coupled to the arm sections and has a spring force selected to compensate for a weight force of the second arm section and of the projection apparatus fastened thereon over substantially an entire rotational excursion of the second arm section relative to the first arm section. A presentation apparatus having the supporting arm is also provided.
