Rotor launching toy
Abstract
Abstract D R A W I N G A TOY WHICH FACILITATES THE LAUNCHING OF A LARGE ROTOR, COMPRISING AN ELONGATED FRAME WITH A LAUNCHING END HAVING A DRIVE DOG FOR RECEIVING THE ROTOR AND AN OPERATING END WHERE A HANDLE IS LOCATED THAT CAN BE PULLED BY A CHILD TO ROTATE THE DRIVE DOG AND LAUNCH THE ROTOR. THE AXIS OF THE DRIVE DOG IS ANGLED AWAY FROM THE VERTICAL SO THAT THE ROTOR WILL NOT HIT A CHILD AT THE OPERATING END. THE LAUNCHING MECHANISM INCLUDES A CABLE HAVING ONE END NORMALLY WOUND AROUND A SPOOL FIXED TO THE DRIVE DOG, AND AN OPPOSITE END EXTENDING THROUGH THE FRAME TO THE OPERATING END, WHERE IT IS ATTACHED TO A HANDLE. A CHILD LAUNCHES A ROTOR BY PLACING HIS FEET ON A PAIR OF FOOT RESTS AT THE OPERATING END OF THE FRAME, AND PULLING UP ON THE HANDLE WHICH IS ATTACHED TO THE CABLE.
