Abstract

The present invention is related to an improved fan design. According to an exemplary preferred embodiment, the improved fan design of the present invention preferably includes a fan main body having fan blades, a front grill, a flexible guide cone, an air inlet, and supporting legs movable from a first position to a second position. According to preferred embodiments, the flexible guide cone is preferably also movable from a first position to a second position. In the first position, the flexible guide cone preferably forms a first shape which conforms to the surface of the air inlet. In a second position, the flexible guide cone preferably extends away from the air inlet.

First claim

What is claimed is:

1. An air circulation system, wherein the air circulation system comprises:
a fan main body, wherein the fan main body encloses a plurality of fan blades;
a front grill;
a front supporting leg, wherein the front supporting leg comprises a front lower leg portion; wherein the front supporting leg is movable from a first position to a second position; wherein the front lower leg portion is located beneath the fan main body when the front supporting leg is in the first position; further wherein the front lower leg portion is positioned above the fan main body when in the front supporting leg is in second position;
a rear supporting leg, wherein the rear supporting leg comprises a rear lower leg portion; wherein the rear supporting leg is movable from a third position to a fourth position; wherein the rear lower leg portion is located beneath the fan main body when the rear supporting leg is in the third position; wherein the rear lower leg portion is positioned above the fan main body when the rear supporting leg is in the fourth position;
an air inlet grill, wherein the air inlet grill is configured to allow air to flow into the fan main body; and
a flexible guide cone; wherein the flexible guide cone is attached to the fan main body; wherein the flexible guide cone is configured to form a first shape and a second shape; wherein the guide cone is configured to conform to the surface of the air inlet when in the first shape; further wherein the guide cone is configured to extend away from the air inlet when in the second shape.

2. The system of claim 1 , wherein the fan main body comprises an enclosing outer surface; wherein the enclosing outer surface comprises PP Copolymer.

3. The system of claim 2 , wherein the fan main body comprises a front bezel.

4. The system of claim 3 , wherein the fan main body comprises a rear bezel.

5. The system of claim 4 , wherein the fan main body comprises a central armature.

6. The system of claim 1 , wherein the front and rear supporting legs form a supporting platform for the fan main body when the front supporting leg is in the first position and the rear supporting leg is in the second position.

7. The system of claim 6 , wherein the front lower leg portion and the rear lower leg portion are proximal to each other when the front lower leg portion is in the third position and the rear lower leg portion is in the fourth position.

8. The system of claim 4 , wherein the front bezel is attached to a front portion of the armature; further wherein the rear bezel is attached to a rear portion of the armature.

9. The system of claim 8 , wherein the front bezel comprises three rigid silicon sections; wherein the front bezel comprises a first front section and a second rear section; wherein the first front section and the second rear section form a first hinge; wherein the first hinge is configured to allow the front bezel to collapse to a reduced depth.

10. The system of claim 9 , wherein the rear bezel comprises three rigid silicon sections; wherein the rear bezel comprises a third front section and a fourth rear section; wherein the third front section and the fourth rear section form a second hinge; wherein the second hinge is configured to allow the rear bezel to collapse to a reduced depth.
