Abstract
An air-flow containment and distribution assembly (10) consisting of a bed sheet (24) or an agricultural parcel cover (22), an air duct (38) and an electric fan (14) that preferably includes a speed control (18) and a heating element (20). The cover (22,24) includes at least one air-duct opening (36) located near an edge of the cover (22,24), and the air duct (38) includes a closed front section (48) and an open rear end (50). The duct's front section (48) has a bulbous shape (58) and a rectangular opening (52) dimensioned to be attached to the air-duct opening (36) and the rear end (50) forms a shroud (56) that attaches to the fan (14). When the bed sheet (24) is placed over a bed mattress (100), the air (12) from the fan (14) flows through the air duct (38) and under the sheet (24) to maintain a person or persons under the bed sheet at a selectable air flow and temperature. Likewise, the air flowing under the agricultural parcel cover (22) safeguards the produce from damaging adverse weather.
