Abstract:
An air-flow containment and distribution assembly comprising:a) an electric fan having an outer circumference and a fan speed control which selectively controls the air flow, wherein said electric fan further comprises a heating element that produces a heated air flow, b) a cover adapted to be placed over a substantially flat area having a front edge, a rear edge, a right edge and a left edge, c) at least one air duct opening located proximal to one of the edges of said cover, wherein said at least one air duct opening is substantially laterally centered and is comprised of a single air duct opening having a rectangular shape and located proximal to the rear edge of said bed sheet; and d) means for applying the air flow into said at least one air duct opening, wherein the air flows into said cover and vents out from at least one of the edges of said cover, wherein said means for applying the air flow from said fan into the single air duct opening comprises an air duct made from a cloth and consisting of an upper panel, a lower panel and two side panels, wherein when said panels are attached, by an attachment means, said air duct has a closed front section, an open rear end, and proximal to an edge of the closed front section and the lower panel is located a rectangular opening that is dimensioned to be attached, by an attachment means, over the single air duct opening on said bed sheet, wherein the open rear end forms a shroud that is attached, by an attachment means, around the circumference of said fan, wherein when air is flowing through said air duct the air impinges on the closed front section of said air duct to form a bulbous section having a curvature which aids in directing the air flow into the rectangular opening and the air duct opening on said bed sheet, wherein when the rectangular shape opening on said air duct is attached to the air duct opening on said bed sheet an inner extending tab is formed, wherein when the air flow impinges on the tab, the air is reflected in a direction which aids to maintain the curvature of the bulbous section.
