Abstract: 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.
