Abstract
A window fan which can easily installed in a window opening without requiring the use of extraneous tools or mounting hardware. In one embodiment, the window fan comprises a housing, the housing is generally box-like in shape and is dimensioned for use with virtually any double-hung window. Disposed within the housing is a fan unit comprising a motor and a propeller-like blade rotatably mounted on the motor. The top portion of the housing is shaped to include a lip and, in addition, is shaped to include an elongated, recessed tray which extends transversely below the lip. A C-shaped clip, having a tab adapted to engage the opposite side of a closed window, is movably mounted along the longitudinal axis of the tray and includes a pair of outwardly-extending, spring arms which arc adapted to matingly engage alternative, spaced-apart sets of grooves formed on opposing side walls of the tray for use in locking the clip at specific locations within the tray.
