Claims
- 1. An aerial toy that is adapted to be launched into the air using an elastomeric band, said toy including:
- (a) a nose portion that is generally in the shape of an elongate ellipsoid, said nose portion having a front end and a rear end;
- (b) an elongate rib depending from the rear end of the nose portion in a direction generally along the long axis of said nose portion, said rib having a first end adjacent to the nose portion, and a second end;
- (c) a first generally planar wing portion that:
- (i) depends from the rear end of the nose portion;
- (ii) depends from the rib;
- (iii) has a tapered outer edge; and
- (d) a second generally planar wing portion that:
- (i) depends from the rib; and
- (ii) has a surface area approximately 20-80% as large as the surface area of the first wing portion;
- wherein the plane of the first wing portion is generally parallel to and spaced apart from the plane of the second wing portion.
- 2. The aerial toy of claim 1, wherein the second wing portion has a surface area approximately 20-50% as large as the surface area of the first wing portion.
- 3. The aerial toy of claim 1, wherein the second wing portion depends from the rear end of the nose portion.
- 4. The aerial toy of claim 1, wherein the nose portion has a first side and a second side, a notch across the short axis of the first side near the front end, and an appendage adjacent to said notch, and wherein the notch and the appendage are adapted for receiving the elastomeric band of a launcher.
- 5. The aerial toy of claim 1, wherein the first wing portion is of increasing width from a first point adjacent to the nose portion to a second point near the second end of the rib.
- 6. The aerial toy of claim 1, which is adapted to rotate about an axis passing through its center of mass and generally through the center of mass of the Earth as it descends from its maximum altitude.
- 7. The aerial toy of claim 1, which is made from a material selected from the group consisting of polyethylene, polypropylene, urethane foam and styrene foam.
- 8. The aerial toy of claim 1, wherein the outer edge of the first wing portion is tapered along at least about 20% of its length.
- 9. The aerial toy of claim 8, wherein the outer edge of the first wing portion is tapered from a point where it joins the second end of the rib along the periphery thereof in a direction towards the nose portion.
- 10. The aerial toy of claim 1, wherein the rib provides a pair of angled substantially planar transitions from the first wing portion to the second wing portion.
- 11. The aerial toy of claim 10, wherein the transitions are parallel and are disposed at an angle within the range of about 30.degree. to about 60.degree. between the plane of the first wing portion and the plane of the second wing portion.
- 12. The aerial toy of claim 1, wherein at least about 30% of the total mass thereof is in the nose portion.
- 13. The aerial toy of claim 12, the center of mass of which is located near the junction of the rib and the nose portion.
