US Patent 9677565 Hand crank-powered fan

A powered fan is provided having a fan housing, a plurality of fan blades, a motor, and an electrical generation system. The fan blades are mechanically coupled to the motor, both being contained within the fan housing. Rotatably affixed to an exterior portion of the fan housing, and mechanically coupled to the electrical generator, is a hand crank. Electrically coupled to the motor and affixed to some portion of the fan housing is a rechargeable battery. Manipulation of the hand crank generates electricity for powering the motor and/or charging the rechargeable battery. A control pad located on the fan housing allows a user to selectively control the functioning of the fan.
