Abstract: A vertically adjustable post for a tripod (1) for a film or television camera wherein a pneumatic piston-cylinder assembly (4) is used as a vertically adjustable element. In order to obtain uniform camera support over the whole range of adjustment of the pneumatic assembly (4), the piston rod (12) of the pneumatic assembly (4) is frusto conical. The piston rod (12) is sealed against the cylinder (14) of the pneumatic assembly (4) by means of a radially resilient seal (15) which adapts to the varying diameter of the piston rod (12).

Abstract: A motion picture or television camera stand is disposed on a running support consisting of a central body with three arms. The arms are provided each on their free ends with a set of wheels, the wheels being steerable through a central steering system which has a steering wheel disposed around the central column of the stand and fastened thereon, an upper central cogwheel mounted on the central column, a steering shaft rotatably mounted on the central column and extending parallel to the latter, with a pinion on its upper end cooperating with the upper central cogwheel and a pinion on its lower end cooperating with the lower pinion of the steering shaft in the central body of the support and one cogbelt drive from the lower central cogwheel to each cogwheel on the shafts bearing the running wheel sets. The stand is made to be removable from the support. Two of the arms of the support are foldable against the third arm.
