ABSTRACT:
A rotating umbrella includes a canopy which serves a fan. The umbrella canopy is formed by a plurality of segmented petals extending radially outwardly in a fan-like fashion, and connected to a hub mounted on a shaft. The shaft includes a drive shaft member coupled to a second shaft member which connected to the hub at its upper end, wherein the drive shaft member is powered by a motor such that it rotates and operatively engages the second shaft member to rotate the hub and the petals of the canopy. The motor and the drive shaft both mounted on a base plate on the ground to stabilize the umbrella. A cooling breeze is produced when the petals are rotated to deter flying insects and to shield a person setting beneath the umbrella from the elements.
