PCT No. PCT/CH95/00009 Sec. 371 Date Aug. 19, 1996 Sec. 102(e) Date Aug. 19, 1996 PCT Filed Jan. 13, 1995 PCT Pub. No. WO95/23532 PCT Pub. Date Sep. 8, 1995A standing umbrella has a mast on which the inner end of an outwardly and inwardly movable carrier beam is guided with the outer end of the beam carrying an umbrella stick of a collapsible umbrella and with the carrier beam being held by a connecting strut linkedly arranged between the upper end of the mast the carrier beam. A drive mechanism shifts the inner end of the carrier beam along the length of the mast and the mast has two guide tracks spaced from one another and so profiled that guide elements running there along and carried by the inner end of the mast are held by the shape of the tracks against movement transversely to the direction in which the inner end of the carrier beam is shifted; and the drive mechanism for shifting the inner end of the carrier beam and a drive mechanism for opening and closing the umbrella are so combined with one another that they operate simultaneously in common.
