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 handle extending out through a longitudinal slot in the shaft. The rib carrier is slidable by means of the handle 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. Locking means provided on the rib carrier engage inner ends of the ribs so as to hold them approximately perpendicular to the shaft when in open position. The rib carrier is retained in open and closed positions by a bullet-type spring latch. The cover is provided with pockets to receive outer ends of the ribs and is preferably formed of two-way stretch material.
An umbrella comprising an elongate tubular shaft having upper and lower ends and having a longitudinally extending slot between said ends, rib carrier means longitudinally movable in said shaft, a plurality of elongate rib members having inner and outer ends, means pivotally connecting said rib members near their inner ends to said rib carrier means, means fixed to said rib carrier means and projecting out through said slot in said shaft for moving said rib carrier means longitudinally in said shaft between a closed position in which said rib carrier means is near the lower end of said shaft and said rib members are in said shaft and an open condition in which said rib carrier means is at the upper end of said shaft and said rib members radiate from said rib carrier means, latch means for releasably securing said rib carrier means in said open and closed positions, locking means on said rib carrier means for retaining said rib members approximately normal to said shaft when in open position, a flexible fabric cover secured at its center to said rib carrier means and at its periphery to outer ends of said rib members, said cover overlying and being supported by said rib members when in open position and being drawn down into said shaft with said rib members when said rib carrier means is moved to closed position.
