An umbrella assembly (10) comprises a canopy frame (14) and a support structure therefore that includes means for suspending said canopy frame (14), that comprises a curved pole (38) having an upper end coupled with the canopy frame (14). The support structure also includes a second pole supporting said curved pole and having a lower end, an upper end, and a longitudinal axis, and a junction adjacent said upper end of said second pole that defines a passageway through which the curved pole can be moved generally transversely to the longitudinal axis of the second pole. The umbrella also includes an extension mechanism (22) and a canopy deployment mechanism (26). The extension mechanism (22) is coupled with the support structure and is configured to be driven by a crank to move the curved pole through the passageway to extend or retract the curved pole. The canopy deployment mechanism (26) is coupled with the support structure and is configured to be driven by a crank of the extension mechanism (22), to open and close the canopy frame (14). The means has a lower end which can be retracted to a position where said lower end of said extends below and beyond the passageway.
