Abstract
An aerodynamic toy adapted to be thrown through the air having a dish shaped body which is substantially hemispherical in shape and which has a rim integral with the body that provides balance and stability when the toy is thrown. The rim has upper and lower parallel surfaces that are substantially perpendicular to the axis of the body and a frusto-conical outer surface. The toy is sized to be grasped with the index finger and thumb extending about the body adjacent the rim in opposite directions and with the middle finger lying against the bottom of the rim.
Claims4
An aerodynamic toy adapted to be thrown through the air comprising:
- a substantially hemispherically shaped body formed of a strong and resilient material and having a substantially hemispherically shaped cavity disposed therein, said body having an axis extending normally from a plane defined by a base of said body, said cavity progressively increasing in cross sectional area toward said base;
- and
- a solid rim disposed around the outer surface of said body closely adjacent said base and projecting outwardly away from the outer surface of said body, said rim having an upper surface spaced from said base and extending generally normally to said axis of said body and an outer frusto-conically shaped wall extending from said upper surface inwardly and downwardly toward said base, said rim reinforcing said body adjacent said base and providing aerodynamic balance to said toy during flight.
