Abstract

The invention relates to an aerodynamic toy (1, 2) that has two concave portions (15 and 25 or 35 and 45), enabling the aerodynamic toy (1, 2) to be launched in any orientations. The aerodynamic flying toy has a central portion that is circular in form and circumscribed at its peripheral edge by a first annular flange curving upwardly laterally towards the centre of the central portion to form a first concave portion and by a second annular curving downwardly laterally towards the centre of the central portion (10) to form a second concave portion. The curved surface on the concave side of the annular flange of the aerodynamic flying toy can be further provided with a plurality of spaced apart ribs or ridges.

Claims

1. An aerodynamic flying toy (1) comprising a central portion (10) that is circular in form circumscribes at the peripheral edge by a first and a second annular flanges (11, 21) wherein

the first annular flange (11) circumscribes the peripheral edge of the central portion (10) and curving upwardly laterally towards the centre of the central portion (10), terminating in a first rim (12), and with the inner surface of the first annular flange (11) and the central portion (10) forming a first concave portion (15) of the aerodynamic flying toy (1);

the second annular flange (21) circumscribes the peripheral edge of the central portion (10) and curving downwardly laterally towards the centre of the central portion (10), terminating in a second rim (22) and with the inner surface of the second annular flange (21) and the central portion (10) forming a second concave portion (25) of the aerodynamic flying toy (1); and

the central portion (10), the first and second annular flanges (11, 21) are a single unit of unitary construction manufactured integrally by injection moulding of plastic.

2. An aerodynamic flying toy (1) as in claim 1, wherein each annular flange (11, 21) merges with the central portion (10), at the peripheral edge of the central portion (10), in a curved and smooth transitional manner.

3. An aerodynamic flying toy (1) as in claim 2, wherein the area (13, 23) where the annular flanges (11, 21) merge with the central portion (10) is a filleted joint.

4. An aerodynamic flying toy (1) as in claim 1, wherein the annular flanges (11, 21) merge with one another at the external circumference, providing a cross sectional profile for the combined annular flanges (11, 21) that yields an external convex surface that has a suitable aerodynamic shape.

5. An aerodynamic flying toy (1) as in claim 4, wherein the shape of the cross sectional profile of annular flanges (11, 21), excluding the central portion (10), resembles a wedding ring but with a wider flange or a tyre but with a narrower flange.

6. An aerodynamic flying toy (1) as in claim 4, wherein the cross section profile of the combined annular flanges (11, 21) is the arc of the leading edge on the major axis of an ellipse.

7. An aerodynamic flying toy (1) as in claim 6, wherein the ellipse may have varying eccentricity.

8. An aerodynamic flying toy (1) as in claim 1, wherein the size of the annular flanges (11, 21) is selected such that the aerodynamic flying toy (1) may be conveniently gripped by placing the fingers on the convex side of the annular flanges (11, 12) or on the rims (12, 22).

9. An aerodynamic flying toy (1) as in claim 1, wherein the aerodynamic flying toy (1) is further provided with at least one spaced apart rib or ridge each (16, 26) between the rim (12) and the central portion (10) and between the rim (22) and the central portion (10) respectively, the rib or ridge (16, 26) run circumferentially around the aerodynamic flying toy (1) in planes parallel to the plane of the central portion (10).

10. An aerodynamic flying toy (1) as in claim 9, wherein the widths of the or each rib or ridge (36, 46) is such that the circles formed by the loci of the free end of the or each rib or ridge (36, 46) has the same or greater radius than the circle formed by the loci of the rim (12 or 22).

11. An aerodynamic flying toy (1) as in claim 1, wherein the convex side of the annular flanges (11, 21) are provided with ridges to facilitate better frictional grip by the user.

13. An aerodynamic flying toy (1) as claim 2, wherein the convex side of the annular flanges (11, 21) are provided with ridges to facilitate better frictional grip by the user.
