A mount for a shade structure, in particular a collapsible pavilion. The mount has a base and a cover. The base has a space formed therein configured to receive a ground support of a shade structure. The cover has a top surface and a bottom surface to be secured to the base. A groove is formed in the mount and is configured to pivotably receive a rib. The groove is disposed between opposed walls of the mount. A pin retention recess is disposed on each side of the opposed walls in one of the cover and the base. A plurality of projections are provided that each have a first end fixed to one of the cover and the base in which the pin retention recess is not formed and a second end disposed away from the fixed end. One of the projections is configured to enclose a portion of the retention recess when the cover and the base are secured together.

The umbrella having an expandable canopy is an umbrella with a canopy of adjustable size. The umbrella having an expandable canopy is an umbrella that is further modified with a plurality of additional runners and stretchers which, when opened, are used to extend the effective diameter of the canopy to increase the protected area underneath the umbrella. The umbrella having an expandable canopy comprises a modified umbrella, a secondary canopy, a plurality of secondary stretchers, a plurality of modified ribs, a secondary runner, and a secondary top tip spring.

An umbrella includes an anti-inversion mechanism that is configured to apply to each rib assembly a force that counters an inversion force that is applied to the umbrella. The anti-inversion mechanism includes a first rib joint that is coupled to first and second ribs, a first elongated member that is coupled to the first rib joint and a second elongated member that is coupled to the first elongated member and to the distal rib. The first rib joint includes an inner slot and the first elongated member comprises a wire having a bent clip portion at a first end of the wire, the bent clip portion being received within the inner slot and being biased against a floor of the inner slot resulting in the wire being attached to the first rib joint.

Provided is a sunshade umbrella, including an umbrella pole, an umbrella frame, and a base, wherein the umbrella pole is disposed on the base, and the umbrella frame is connected to the umbrella pole. The umbrella pole is provided with a hand-crank portion, a pull rope is wound around the hand-crank portion, and the hand-crank portion drives the umbrella frame to deploy or retract by retracting or releasing the pull rope.

An umbrella has a column, an upper nest, a movable lower nest, a plurality of long rods, a plurality of short rods. The upper nest has a plurality of first slots spaced apart on a periphery of the upper nest, a plurality of first pins is disposed on the upper nest respectively; each long rod has a first rod-hanging hook on the top end thereof, each first rod-hanging hook hooks on the corresponding first pin; the lower nest has a plurality of second slots spaced apart on a periphery of the lower nest, a plurality of second pins are disposed on the lower nest respectively; each short rod has a second rod-hanging hook on the bottom end thereof, each second rod-hanging hook hooks on the corresponding second pin. The structure of the present invention is simple and reasonable, the machining is convenient and the cost is low.
