Abstract
A toy helicopter having a hollow body member configured to simulate a helicopter with a main body portion and a tail section, the main body portion supporting a helicopter rotor on a shaft member extending through the roof thereof, the shaft being rotatably supported by a pair of bearings, with a reel portion configured in the shaft intermediate the bearings. The reel portion has encircled thereabout a flat constant torque coil spring acting as a spring clutch, the free end of the coil spring being secured to one end of a trigger member, which is pivotally secured within the housing. The main body portion is provided with a pair of aligned openings through which an operator can manipulate the trigger whereupon repeated pivoting of the trigger causes the shaft to continuously rotate in a given direction. The helicopter is also provided with a hand-operated winch and a water-squirting apparatus actuated by a second trigger.
