Throwing toy with improved adjustable and time flight measurement

摘要

Apparatus and method of adjusting the angle of attack to the longitudinal axis of a plurality of aerodynamic surfaces on a high performance throwing toy which affect the performance of such toy and to also provide a means of measuring such performance by recording the time the toy is airborne during flight.

主权项

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 rotatable adjustment ring rotatably connected to said main body by a ratchet mechanism such that said rotatable adjustment ring is rotatable with respect to said main body; a fin mounting portion integrally connected to said trailing end of said main body and having an exterior surface, said fin mounting portion extending rearwardly of said main body, 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, said leading edges of said fins being connected to said rotatable adjustment ring, and said trailing edges of each of said plurality of fins being connected to the fin mounting portion for rotation of the leading edges of said fins relative to the fin mounting portion and trailing edges of said fins, said leading edges of said plurality of fins being configured to be rotated simultaneously together relative to the fin mounting portion and trailing edges of said plurality of fins to present a plurality of aerodynamic surfaces oriented with the same aerodynamic angle of attack.
