  • Patent number: 4084600
    Abstract: 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.
