Patent ID: 7487620

Claim:
A wind directional exhaust vent and skylight combination comprising: a rotatable hood having a mounting means for rotatably securing the rotatable hood to a stationary building structure, the rotatable hood, having a throat terminating in a mouth, in communication with a cavity in the structure to be exhausted; a wind directional means on or forming part of the hood effective to rotate the hood such that in response to wind the mouth tends to face the leeward wind direction to reduce rain penetration through the mouth into the throat and increase exhaust suction; and a vertically extending, stationary drag inducer mounted on or forming part of the hood immediately above the mouth; wherein the rotatable hood includes at least one wall made from light transmitting material permitting the passage of ambient light and sunlight therethrough and into the cavity; and wherein a wind induced flow of air over the drag inducer creates a pocket of air having negative pressure immediately adjacent the mouth for further inducing an exhaust flow of air outward from the cavity.
