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.

Claims

1. An air cooled umbrella comprising a rod having opposite top and bottom ends, a handle with a hand grip on the bottom end of the rod, a runner mounted on the rod, a collapsible canopy mounted on the rod adjacent the top end thereof and incorporating a plurality of elongate flat ribs, a plurality of stretchers extending between the canopy and flat ribs, each of the flat ribs being formed along its length with a plurality of holes extending through the canopy for venting hot air from under the canopy, through the canopy, when opened.

2. An air cooled umbrella as recited in claim 1, further including an electric fan 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.

3. An air cooled umbrella as recited in claim 2, wherein said electric fan includes:

a) a motor with transmission assembly carried within a top end of the rod; and

b) a fan blade assembly connected to said transmission assembly and rotatable on the top end of the rod.

4. An air cooled umbrella as recited in claim 3, further including a solar cell panel mounted to the apex of the capopy and electrically connected to said motor, so as to supply power to said electric fan on hot sunny days.

5. An air cooled umbrella as recited in claim 4, further including:

a) an electric socket on a bottom end of said handle electrically connected to said motor; and

b) a rechargeable handle battery pack having an electric plug on one end to be inserted into said electric socket, so as to supply power to said electric fan on hot sunless days and nights.

6. An air cooled umbrella as recited in claim 5, further including:

a) means for alternatively permitting electric power for activating said electric fan to be selected from said solar cell panel or said rechargeable handle battery pack; and

b) means for alternatively permitting said rechargeable handle battery pack to be charged from either said solar cell panel or a separate charger assembly.

7. An air cooled umbrella comprising a rod having opposite top and bottom ends, a runner mounted on the rod, a collapsible canopy mounted on the rod adjacent the top end thereof, and a plurality of stretchers extending between the canopy and the runner, the canopy incorporating a plurality of flat ribs, each being formed with at least one hole extending through the canopy for venting hot air from under the canopy, through the canopy, when opened.
