Abstract
Abstract THERE IS DISCLOSED HEREIN A TOY ARRANGEMENT UTILIZING PRINCIPALS OF AERODYNAMICS TO PROVIDE AN AERODYNAMICALLY ACTUATED TOY OR DISPLAY DEVICE. A MULTIBLADED AERODYNAMIC MEMBER IS COUPLED TO A GENERALLY TUBULAR MEANS FOR ROTATION THEREWITH UNDER THE INFLUENCE OF AIR FLOW OVER THE MULTIBLADED AERODYNAMIC MEMBER. WHEN SUCH AIR FLOW OCCURS, THE AERODYNAMIC MEMBER ROTATES AND, IN SO ROTATING GENERATES A LIFTING FORCE. THE TUBE MEANS IS MOUNTED FOR ROTATIONAL MOVEMENT ON A ROD MEMBER AND AS THE BLADE MEMBER ROTATES, THE BLADE AND TUBE MOVE ALONG THE ROD MEMBER DUE TO AERODYNAMIC LIFE GENERATED BY SUCH ROTATION.
