ABSTRACT:
A fan (10) is disclosed that includes a first leg (20) and an interconnected second leg (30), the legs (20,30) being movable relative to each other between a first, closed position and a second, open position. A blade (41) is secured to and disposed between the two legs (20,30) generally adjacent the top (13) of the fan (10). A torsion spring (50) having a coil (51) and two projecting arms (52), with each arm (52) abutting one leg (20,30) is adapted for biasing the legs (20,30) to the open position. A release mechanism (54) adapted for releasably locking the legs (20,30) in the closed position has a post (55) attached to and projecting from the second leg (30) and a barb (56,56a,56b) at the distal end thereof adapted for cooperating with an aperture (57) in the first leg (20) when the legs are in the closed position.
