Abstract
A stick-propelled disk game is presented. Fundamentally, the invention includes an annular disk characterized by a central opening therein. The disk is caused to fly through the air and is retrieved therefrom by means of a stick which is insertable into the opening. The central opening and the outside circumference of the disk are circumscribed by circumferential edges of a greater thickness than the disk proper, such circumferential edges protruding equidistance above and below the surfaces of the disk portion therebetween. These circumferential edges, in combination with the disk surface, comprise a cup for aerodynamic stability, with such a cup existing on both sides of the disk.
Claims3
A stick-propelled disk game, comprising:
- an annular disk having an opening centrally located within said disk, said disk having an inner circumferential edge about said opening having rounded edges for maintaining laminar flow of air over said disk during flight;
- an outer circumferential edge about the outside circumference of said disk having rounded edges;
- said circumferential edges being of a thickness greater than the thickness of the portion of said disk therebetween, such difference in thicknesses defining an aerodynamic cup between said circumferential edges;
- said circumferential edges extending equidistance above and below the portion of said disk therebetween and thereby defining aerodynamic cups on upper and lower surfaces of said disk;
- wherein said inner circumferential edge is of a width approximately equal to fifteen percent of the overall width of said disk between said opening and said outer circumferential edge of said disk, and wherein said outer circumferential edge is of a width approximately equal to one-half of the width of said inner circumferential edge;
- and
- at least one stick for engagement with said opening for propelling and retrieving said disk.
