ABSTRACT:
A fan having a rectangular frame including a bottom wall, two side walls, and a top wall, and a motor-driven impeller supported within the frame for causing air to move through the frame in an axial direction. The frame has at least one, and preferably two, stabilizing feet moveable between an extended position, in which each foot projects axially beyond the contour of the fan frame, and a retracted position, in which the foot does not project axially beyond the contour of the fan frame. Resilient elements, such as springs, constantly urge the stabilizing feet toward their extended positions. The stabilizing feet may be pivotally mounted on the fan frame, and stops are provided against which each foot abuts when the foot is in its extended position. A packing box snugly accommodates the fan during storage and shipment of the fan, and the stabilizing feet engage the interior surface of the box so that the box retains the feet in their retracted positions against the force of the resilient members, the resilient members serving to automatically spring the feet into their extended positions upon removal of the fan from the box.
