ABSTRACT:
An air cooled umbrella is provided having a rod, a handle with a handgrip, a top spring, a runner, a plurality of stretchers, and a collapsible canopy. A plurality of flat ribs are under the canopy. Each flat rib has a plurality of holes therethrough for venting hot air from under the canopy when opened. An electric fan is built into the rod directly under the canopy, so as to speed up the venting of the hot air and to supply cool air to a person under the canopy. The fan may be supplied power from a solar cell panel mounted on the canopy of the umbrella or alternatively from a separate rechargeable handle battery pack. The separate rechargeable handle battery pack may be charged by either the solar cell panel or a separate house current wall socket charger assembly.
