Abstract

An electric fan assembly for household use convertible between use in a window and use on a desk or floor has a substantially rectangular, one-piece, molded polypropylene support member formed from a first support panel, a second support panel, and a pair of living hinges connecting the first and second panels to one another along a pivot axis perpendicular to the top and bottom edges of the support member. The first support panel is constructed to provide a mounting for an electric fan motor, a venturi ring assembly including an intake grill, and an exhaust grill. In use, the two support panels may lie flat for use in a window or may be pivoted about the axis of the living hinges for use on a deck or floor. Extenders are provided for extending the effective width of said fan assembly for use in relatively wide windows and includes secondary extender plates connected to the extenders by lost motion for increasing the length of extension obtainable. The exhaust grill is optionally mounted for rotation.
