Abstract: An umbrella has a canopy, a main shaft and a plurality of ribs pivotally attached to the main shaft, each rib being of adjustable length and including a pair of outer rib elements, wherein the outer rib elements are flexible and normally adopt a straight configuration aligned with the main shaft in a closed position of the umbrella, and in an open position of the umbrella, flex so that outer ends of the outer rib elements extend generally circumferentially with respect to the canopy. The umbrella can have ribs that would normally be of one piece, in which case accommodation is made for an effective change in the radius of the ribs as the outer rib elements flex. The umbrella may be a folding umbrella with two part ribs. The outer ribs can have a non-uniform cross-section and may taper.

Abstract: A tip element, for mounting on to a rib of an umbrella frame, comprises a pair of wings, and optionally a mounting portion for mounting onto the umbrella rib. The wings at least defining an outer edge for a canopy mounted on the umbrella frame, wherein one wing may be mounted for pivotal movement relative to the umbrella rib. The wings, or at least one of the wings, can be pivotally mounted to the mounting portion by living or other hinges. Alternatively, the wings can be pivot directly about the umbrella rib.
