Abstract: The telescopic column is provided for a portable stage used in outdoor or indoor events produced in front of audiences or the like and comprising a haulable chassis for overland transportation between events. The column bears a roof movable vertically above the chassis and comprises a plurality of C-shaped beams operatively fitted into each other and concentric with a central beam. A plurality of pairs of upper rollers, each operatively connected to an upper end of a corresponding C-shaped beam, are provided for engagement with the surface of an adjacent interior beam and for rolling thereon upon raising or lowering of the roof. The use of rollers prevents jamming of the C-shaped beams when moving the roof vertically.
