Abstract:

First and second elongated coaxial tubular members are slidably related for relative longitudinal movement. The first member carries a cylindrically shaped pivot block to which are pivoted a plurality of circumferentially spaced pivot pieces, for pivotal movement towards and away from the first member. A collapsible umbrella canopy supporting rib extends from each of such pieces. A cup shaped member is attached to the second member and operates simultaneously against the pieces to move them away from the first member and extend the ribs outwardly in canopy supporting position upon relative longitudinal movement of the members.
