Title: AN AERODYNAMIC FLYING TOY
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. In one embodiment, the aerodynamic flying toy has a central portion that is circular in form and substantially flat 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. In another embodiment, the aerodynamic flying toy has a central portion that is circular in form and substantially flat surrounded at its peripheral edge by a first circumferential flange that projects upwardly laterally away from the centre of the central portion to form a first concave portion and by a second circumferential flange that projects downwardly laterally away from the centre of the central portion to form a second concave portion of the aerodynamic flying toy. The ends of the circumferential flanges external to the concave portions are provided with a plurality of spaced apart ribs or ridges.
