The top wall 22 has a hole 28 therethrough. The peripheral wall 26 has an opening 30 therein. The bottom wall 24 has a plurality of rods 32 securely coupled thereto and extending into the ground surface 8 .

Each of a pair of bracket members 34 is securely coupled to an upper surface of the bottom wall 24 and spaced from each other.

A first axle 36 is elongate and has a first end 38 rotatably coupled to a bottom surface of the covering 16 . The first axle 36 extends through the hole 28 in the top wall 22 of the gear housing 20 such that a second end 40 of the first axle 36 is positioned generally between the brackets 34 . The first axle 36 has an upper portion 42 positioned outside of the gear housing 20 and a lower portion 44 positioned inside of the housing 20 . The upper portion 42 has a diameter greater than a diameter of the hole 28 .

A second axle 46 is elongate and has first end 48 and a second end 50 . The first end 48 of the second axle 46 extends through a first of the brackets and into a second of the brackets. The second axle 46 is rotatably coupled to the brackets 34 . The second end 50 of the second axle 46 extends through the opening 30 in the peripheral wall 26 .

The second axle 46 extends through and is integrally coupled to a first gear 52 . The first gear 52 is generally positioned between the brackets 34 .

A second gear 54 is integrally coupled to the second end 40 of the first axle and is positioned to engage the first gear 52 . Rotating the first axle 36 causes the second axle 46 to rotate.

Each of a plurality of vanes 60 comprises a top arm 61 , a bottom arm 62 and an end portion 63 . Each of the arms 61 , 62 has a first end securely attached to the upper portion 42 of the first axle 36 and a second end securely attached to an opposite end of the end portion 63 such that a frame is defined.

Each of a plurality of panels 64 is substantially rigid and has a front side 65 , a back side 66 , a top edge 67 , a bottom edge 68 , a first side edge 69 and a second side edge 70 . Each of the top edges 67 is hingedly coupled to one of the top arms 61 and each of the bottom edges 68 is hingedly coupled to one of the bottom arms 62 on the same vane 60 by a plurality of hinging means 71 . Each of the hinging means 71 extends the length of a respective panel and is positioned adjacent to a respective first side edge 69 . Each of the panels 64 is spaced such that a front side 65 of a panel 64 may abut a back side 66 of a next adjacent panel. The panels 64 may selectively move between an open position and a closed position. Each of the vanes 60 has a plurality of panels 64 hingedly coupled thereto.

A second embodiment is shown in FIGS. 6 and 7 and includes a base member 72 . The base member 72 has a top side 73 has a generally arcuate depression 74 therein in the shape of a half-cylinder.

A drainage hole 75 extends through a bottom most portion of the arcuate depression. A drainage pipe 76 is fluidly coupled to the drainage hole 75 and outwardly away from the base member to carry away any water that may accumulate in the depression.

Each of a pair of bracket members 77 is securely coupled to the top side 73 and positioned on either side of the depression 74 .

An axle 78 is elongate and has first end and a second end. The axle 78 extends through and is rotatably coupled to each of the brackets 77 . The vanes 60 and their associated panels 64 are coupled to the axle 78 as in the first embodiment shown in FIGS. 1 through 5 . The first embodiment is vertically positioned and the second is horizontally. The second device is more useful on the western coast of the United States where the wind is generally directed in a first direction.

In use, the device is used as a conventional windmill, however it is capable of drawing more power from the wind because as the panels close, the vane becomes, in essence a solid wall with the ability to catch more air. As the first axle rotates, the wind causes the panels to open so that it may generally pass unimpeded through the vane. The axle may be mechanically coupled to generator, pump, or anything needed by the user.

As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
