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).
