TITLE OF THE INVENTION: Umbrella ABSTRACT OF THE DISCLOSURE: The inner ends of cover-supporting ribs of an umbrella are pivotally connected to a rib carrier which is longitudinally slidable in a hollow shaft by means of a projection extending out through a longitudinal slot in the shaft. The rib carrier is slidable between a closed position in which the rib carrier is near the lower end of the shaft and the rib members together with the cover are in the shaft and an open position in which the rib carrier is at the upper end of the shaft and the rib members radiate out from the rib carrier so as to support the cover. Each of the ribs comprises inner and outer tubular sections which are telescopically slidable one in the other. When the umbrella is in open position, the telescopic ribs are extended so as to support a larger cover. When the umbrella is in closed position the telescopic ribs are contracted so as to be received in a shorter shaft. The ribs are biased to extended [position by an internal spring and latch means is provided for releasably holding the ribs in contracted condition. A handle portion which is telescopically received in the lower end portion of the shaft releases the retaining latches of the ribs so that the ribs are extended when the handle portion is pulled out of the shaft to a single piece of two-way stretch material having inwardly opening pockets at its periphery to receive outer ends of the ribs. The cover is stretched when the ribs are in extended open position and contracts with the ribs when the ribs are contracted.
