  • Patent number: 5267735
    Abstract: The javelin is a hand-thrown toy having a tubular fuselage. Mounted on the forward end of the fuselage are four canard planes, and mounted adjacent the rear of the fuselage are four tail planes. The forward surfaces and rear surfaces are each at a right angle and straight with respect to the fuselage to prevent spinning. The forward and rear surfaces are positioned at 45 degrees with respect to each other. The surfaces are sized as compared to fuselage length and weight so that the javelin flies level without spinning. A soft nose ring attached to the forward end of the fuselage prevents damaging impact.
