Eggball
First Claim
1. A ball for amusement exercise and athletic competition comprising in operative combination:
- a) a solid body of generally egg shaped exterior configuration having a first major axis and a second minor axis;
b) the ratio of said major axis to said minor axis lying within the range of about 1.3 to about 1.6;
c) said ball has a first small end generally parabolic in cross section, a second, opposed, larger end of generally hemispherical configuration, and an intermediate zone having a smooth generally flattened curve so that said opposed end smoothly fair into said intermediate zone;
d) said ball is composed of an elastomer having a durometer in the range of from about 30 to about 40;
e) said ball has a length in the range of about 21/2 to about 31/2" along its major axis;
f) said ball has a mass in the range of from about 60 to 120 grams; and
g) said ball is of a size to fit comfortably in the human hand between the index and little fingers and which is controllable to impart spin along selective ones of said axes to control the rebound thereof.

Abstract
An egg-shaped elastomeric ball having a unique combination of texture, size, weight and composition features such that it can be thrown and bounced in a controllable manner, after the user develops a certain level of skill. Methods of manufacture and use in exercise, entertainment and sports are also described. The eggball has a major to minor axis ration on the order of 1.3 to 1.6, and more preferably in the range of 1.4 to 1.5, a major axis dimension in the range of about 23/4 to 31/4", a mass on the order of from 60 to 120 grams, and preferably in the range of from 80 to 100 grams, and an exterior surface that while smooth, is textured and can be characterized as sanded or frosted. The durometer is between 30 and 40 and preferably from about 33 to 37. In the preferred embodiment, the surface texture is sanded, so that the exterior of a transparent composition has a translucent frosted look. For a novelty item the surface may be left smooth, shiny and generally transparent, and may have objects embedded therein. In an important embodiment, a light and battery can be embedded in the center of the eggball so that when the ball strikes a surface, or rotates end-over-end, the light goes on to permit play at night. Similarly a sound device, such as a whistle can be associated with the ball.
