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.
Claims18
An umbrella apparatus comprising first and second members, said second member having upper and lower ends, said members being movable relative to each other;
- a plurality of canopy supporting assemblies, each of said rib assemblies being secured at one end to said first member and pivotable toward and away from said first member, said rib assemblies being swung inwardly toward said first member when said rib assemblies are pivoted to a first position, said ribs being swung outwardly away from said first member when said rib assemblies are pivoted to a second position;
- a cup having a central lower opening defined by an opening perimeter and a central upper opening defined by a cup opening rim, said cup having a sidewall extending between said perimeter and said rim, said cup being secured to the upper end of said second member at said opening perimeter, said side wall of said cup being flared outwardly from said second member to said cup rim, said rim being engagable substantially simultaneously with said rib assemblies as said second member moves relative to said first member to pivot said ribs toward and away from said first member.
