Patent Images
1. A throwing toy having a leading end, and trailing end and a longitudinal throwing axis extending along a length of the throwing toy, comprising:
- a main body having an elongated, ellipsoidal shape, a leading end and a trailing end;
a fin mounting portion integrally connected to said trailing end of said main body and having an exterior surface, said fin mounting portion including a plurality of fins mounted on the exterior surface of said fin mounting portion of the throwing toy, each of said plurality of fins having a leading edge, a trailing edge, and a common aerodynamic angle of attack relative to the longitudinal axis, each of said plurality of fins being connected to the fin mounting portion for rotation of at least one of the leading edge and trailing edge relative to the other of the leading edge and trailing edge, and said plurality of fins being configured to be rotated simultaneously together to present a plurality of aerodynamic surfaces oriented with the same aerodynamic angle of attack, to cause the toy to rotate about the longitudinal throwing axis when the throwing toy is thrown.
