ABSTRACT:
A collapsible umbrella with a three primary rib section type rib linkage system. A first feature of the rib linkage is that a stretcher rib, a control link, a center rib, and a control strut cooperate to define a rib linkage with a profile opening of generally quadrilateral configuration above the stretcher rib when the umbrella is held upright and the rib linkage is between full opened and full closed positions. A second feature is that the stretcher rib is comprised of an inner section, an outer section, and an offset section connecting the inner and outer sections. The offset section is sized and configured so that the inner section provides partial support for the umbrella's cover when the umbrella is opened. A third feature of the system is that a seat is defined in the underside of the control link, and a bend section is provided at the outer end of the stretcher rib, that bend section permitting the outer end of the stretcher rib and the inner end of the center rib to be at least partially received within the control link seat when the umbrella is opened to enhance structural stability of the open rib linkage system.
