A cantilever umbrella characterized by a folding canopy which is mounted in cantilever fashion on a support post rotatably mounted in a base and can be positioned at a selected location in the orbit of the canopy around the support post for shelter against rain or sunlight. In a preferred embodiment a support arm extends in angular relationship from the support post. A canopy support sleeve is mounted on a descending segment of the support arm, and multiple canopy support ribs which support the canopy are pivotally mounted on the canopy support sleeve in radially-extending relationship therefrom. Multiple spreader struts are pivotally attached at one end of each to the corresponding canopy support rib, and the other end of each spreader strut is pivotally mounted on a common strut support sleeve. A winch is mounted on the support post and a cable attached to the winch engages a pulley provided on the strut support sleeve. The canopy of the umbrella is deployed in the open configuration by winding the cable on the winch and thus causing the cable to lift the pulley and attached strut support sleeve as the spreader struts pivot outwardly on the strut support sleeve and respective canopy support ribs and the canopy support ribs pivot outwardly on the canopy support sleeve. A specially-designed lock mechanism is provided on the support post for selectively engaging the base and preventing inadvertent rotation of the support post in the base.

1. A cantilever umbrella comprising a base; a support post carried by said base; a canopy support element supported in cantilever configuration on said support post, said canopy support element disposed in substantially fixed, non-tiltable relationship with respect to said support post; a plurality of canopy support ribs pivotally engaging said canopy support element and extending from said canopy support element in substantially radially-extending relationship; a canopy mounted on said canopy support ribs; a plurality of spreader struts pivotally engaging said plurality of canopy support ribs, respectively; a strut support element pivotally carried by said plurality of spreader struts; a pulley provided on said strut support element; a winch mounted on said support post; and a cable engaging said winch and said pulley, whereby said cable lifts said strut support element, said spreader struts pivot in concert on said strut support element and said support ribs, respectively, and said support ribs pivot in concert on said canopy support element to open said canopy responsive to operation of said winch.
