ABSTRACT:
A portable electric fan including a housing having a front wall defining a front opening for transmitting air, a rear wall defining a rear opening for transmitting air, a top surface, and a bottom surface; a fan blade rotatably mounted in the housing and adapted to move air in a given direction through the front and rear openings; and retainer means projecting upwardly from the top surface and adapted to engage one side of the sash of a vertically movable window. Also included are first and second elongated legs movably mounted in spaced apart positions on the bottom surface and adapted for movement between floor and window positions, each of the legs projecting in the given direction beyond the front and rear walls when in its floor position and extending in longitudinally aligned directions substantially perpendicular to the direction when in its window position. The retainer means and elongated legs facilitate alternative use of the fan for either internal or window applications.
