Abstract

A ventilation fan that functions as a wheel for movements. The generally cylindrical fan housing is pivotally coupled to a triangular handle. The handle may be manually grasped to roll the fan towards an operative position. The handle may be positioned in a temporary storage position, and an inverted, operative position where the drum is elevated for stable use. The drum-shaped fan rolls on its own, and the fan radius becomes the rolling radius. The preferred handle is attached to suitable bearings secured to the guards at the center of each side of the fan. When the destination is reached, the handle is deployed upside-down to function as a support stand, and the fan remains in a stable orientation without moving or shifting its position during operation.

Claims

1. A fan comprising:

a rigid, rotatable drum-shaped housing having an interior and external circumference;

rotatable propeller means disposed within said housing interior for forcing air therethrough;

motor means within said housing interior for actuating said propeller means; and

,

rigid handle means coupled to said drum for rolling the fan.

2. The fan as defined in claim 1 further comprising bearing means for rotatably coupling said handle means to said fan.

3. The fan as defined in claim 1 wherein the handle means can be rotated to an inverted position whereby it functions as a support stand during fan operation.

4. The fan as defined in claim 1 wherein the handle means has a V-shaped configuration with an apex to which the drum is mounted for rotation.

5. The fan as defined in claim 1 further comprising a recessed electrical plug to which electricity may be selectively applied after the fan is set up to operate the motor means.

6. The fan as defined in claim 5 wherein the handle means has a V-shaped configuration with an apex to which the drum is mounted for rotation that enables the handle to be inverted to function as a support stand during fan operation.

7. The fan as defined in claim 1 wherein the motor means is located near the fan bottom to stabilize and balance the fan.

8. The fan as defined in claim 1 wherein tires are formed about the external circumference of said housing.
