Abstract

An improved aerodynamic disc comprised of a disc shaped center, a circumferential rim portion, and a protrusion extending from one surface of the disc shaped center. The protrusion extends beyond the circumferential rim portion to provide a resting support surface. This resting support surface when combined with the resting support surface of the circumferential rim portion in contact with the landing surface provides an opposing elevated rim portion which is designed to aid a pet or a person to retrieve the aerodynamic disc from the landing surface. The protrusion may be permanently affixed or removable and attachment members such as including a whistle element or a light element may be attached to the center shaped disc in addition to the protrusion.

Claims

1. An aerodynamic disc, comprising:

a disc having a convex top, concave bottom and a depending peripheral rim extending downward a particular height, the concave bottom having a threaded mounting boss, the boss extending downward less than the height of the rim;

a flexible protrusion threadedly attachable to the boss so that when tightened, the protrusion is fixed to the boss in a non-rotatable configuration;

the protrusion extending significantly below the height of the rim so that when the disc comes to rest on the ground, it rests at an angle and is supported by the protrusion and a portion of the rim;

the protrusion being substantially flexible so that if the device is stepped upon by a user, the protrusion bends significantly under such force and will return to its original configuration upon the release of such force.
