ABSTRACT:
A propeller launching toy includes a pistol-shaped housing having a movable trigger and a rotatable winding collar. A main shaft is rotatably supported within the housing and is operatively coupled to the winding collar. A main spring is coupled to the main shaft to provide stored energy for rotating the main shaft. A propeller toy having a plurality of propeller blades is releasibly secured to the forward end of the main shaft. A ratchet mechanism is coupled to the winding mechanism to provide single direction motion of the winding collar and main shaft. The trigger is coupled to a pivotable lever which responds to trigger movement to release the engagement of the main shaft and allow rapid spinning of the main shaft which in turn spins the propeller toy. As the propeller toy is rapidly spun, the propeller blades provide aerodynamic lift launching the propeller toy.
