专利汇可以提供Horizontal hinged-flap windmill专利检索，专利查询，专利分析的服务。并且A windmill which rotates in a horizontal plane about a vertical axis includes a plurality of aligned and usually overlapping flaps which move upwardly and downwardly about horizontal hinges to operating and feathered positions as the windmill rotates, with the flaps being held in operating or closed position, at which the force of the wind tends to rotate the mill, by the pressure of the wind against the flaps, which are prevented from feathering by restraining wires or net means, and moving to feathered position as they rotate and their positions are changed relative to the wind.，下面是Horizontal hinged-flap windmill专利的具体信息内容。

权利要求

1. A horizontal windmill which comprises a plurality of flaps or blades which move between feathered positions and operating positions, said flaps each being hinged at a side thereof and so located that when in operating position the flaps or blades overlap, with a side of one flap being pressed against the hinged portion of an adjacent flap, wire mounting means for the flaps on which the hinges are mounted and wire stop means for limiting the motion of the flaps when in feathered position, against which stop means the sides of such flaps bear, which sides are opposite to the sides bearing against the hinge portions of the adjacent flaps in operating position.

2. A windmill according to claim 1 in which the flaps or blades move between substantially horizontal feathered positions and substantially vertical operating positions at which the force of the wind rotates the mill, which has a vertical axis and in which said flaps are hinged horizontally and rotate about such axis in a horizontal plane.

3. A windmill according to claim 2 wherein the flaps are situated in a plurality of banks so that they overlap in operating position, in which they are substantially vertical, so as to inhibit the passage of wind between them, and which includes axial guiding and/or supporting means, a plurality of hubs about said guiding means, a plurality of arms or spokes radiating from said plurality of hubs and thin wire, thread or filament means connecting such arms on one hub with other such arms on another hub to hold the flaps closed in operating position and to allow air to pass readily through those sections in the feathered position, with horizontal wires serving as stops for the flaps or blades to prevent overfeathering thereof.

4. A windmill according to claim 3 wherein the spokes are of rigid material, upper and lower spokes are held together by vertical wires in tension, which wires support horizontal wires on which the flap hinges are mountd and which spokes include additional vertical wires in tension offset from said first set of vertical wires, which second set of wires supports horizontal feathering-stopping wires, which horizontal feathering-stopping wires are free of contacting vertical wires for the widths of the flaps or blades.

5. A windmill according to claim 1 which includes separate sets of wires, one of which sets is for mounting said hinged flaps and another of which sets is for preventing overfeathering of such flaps, which sets of wires are mounted between a pair of parallel horizontal spokes.

6. A windmill according to claim 1 wherein the flaps or blades are made of material selected from the group consisting of polyethylene, polypropylene, aluminum and fiber reinforced polyester.
