Abstract

A free-standing overhead fan apparatus includes a stand and a fan mounted on the stand. The stand includes a base positioned on ground level and an elongated member extending upwardly from the base. The fan is mounted at the upper end of the elongated member, preferably about seven feet above ground level. The fan includes a housing containing an electric motor and a rotating shaft extending from the motor. The fan also includes fan blades radially extending from the motor shaft. The fan is mounted on the stand such that the motor shaft and fan blades are rotatable about a vertical axis to emulate a ceiling fan.

Claims

1. A free-standing overhead fan apparatus, comprising:

stand; and

fan mounted on said stand rotatable about a substantially vertical axis to emulate a ceiling fan, said fan comprising;

a motor;

a shaft extending from said motor rotatable about said vertical axis;

at least one vane extending radially from said shaft, said at least one vane being attached to said shaft via a hinge that allows vertical movement of said vane; and

a locking tab pivotably attached to said shaft, that in a first position allows said vane to rotate freely about said hinge, and in a second position holds said at least one vane in a horizontal position when said locking tab is locked in place.

2. The free-standing overhead fan apparatus of claim 1, wherein said motor is electrically powered.

3. The free-standing overhead fan apparatus of claim 1, further comprising a solar panel device for powering said motor.

4. The free-standing overhead fan apparatus of claim 1, further comprising a rechargeable battery for powering said motor.

5. The free-standing overhead fan apparatus of claim 1, wherein said at least one vane is collapsible for storage and to limit exposure to weather elements.

6. The free-standing overhead fan apparatus of claim 1, wherein said stand is positionable on a given level, and said fan is mounted on said stand a given distance above the given level.

7. The free-standing overhead fan apparatus of claim 1, wherein said stand comprises a base and an elongated member extending from said base, and wherein said fan is mounted on said elongated member.

8. The free-standing overhead fan apparatus of claim 7, wherein said elongated member is at least partly U-shaped.

9. The free-standing overhead fan apparatus of claim 1, wherein stand comprises an elongated member, and wherein said fan is mounted on one end of said member, and an opposite end of said member is removably mountable in a remote socket designed to receive said member.

10. The free-standing overhead fan apparatus of claim 9, wherein said elongated member and said socket include a locking mechanism to releasably lock said elongated member in said socket.

11. The free-standing overhead fan apparatus of claim 1, further comprising an umbrella mounted above said fan.

12. The free-standing overhead fan apparatus of claim 1, further comprising a light source mounted on said fan.

13. The free-standing overhead fan apparatus of claim 1, further comprising a tabletop affixed to said stand.

14. A fan device positionable on a given surface for emulating a ceiling fan, comprising:

an electric fan including an electric motor having a shaft and a plurality of fan blades extending radially from and rotatable by said motor about a substantially vertical axis, said fan blades being attached to said shaft via a hinge that allows vertical movement of said vane, each hinge including a locking tab pivotably attached to said shaft, that in a first position allows said vane to rotate freely about said hinge, and in a second position holds the respective one of said fan blades in a horizontal position when said locking tab is locked in place; and

a stand for supporting the electric fan a given distance above the given surface.

15. The fan device of claim 14, further comprising a solar panel device for powering said motor.

16. The fan device of claim 14, further comprising a rechargeable battery for powering said motor.

17. The fan device of claim 14, wherein said stand comprises a base and an elongated member extending from said base, and wherein said fan is mounted on said elongated member.

18. The fan device of claim 14, wherein stand comprises an elongated member, and wherein said fan is mounted on one end of said member, and an opposite end of said member is removably mountable in a remote socket designed to receive said member.
