Abstract

The amusement device of the present invention comprises a body member formed from a sphere and having six planar surfaces formed on its outer surface. Each of the planar surface is formed at the bottom of a pie-plate shaped indentation in the body member, the indentation having an annular rim around the outer margin thereof, the rim comprising a substantially flat surface. Each of the planar surfaces has raised indicia formed thereon, the raised indicia having a height which is below the annular rims so that the rims prevent the indicia from interfering with rolling of the body member on a flat surface. The surface portions of the body member between the annular rims are spherical in configuration.

Claims

1. An amusement device comprising:

a body member having a substantially spherical shape with six equally-sized indentations formed thereon;

each of said indentations comprising an annular rim, tapered side walls extending inwardly from said annular rim and a flat circular surface positioned radially inwardly from said annular rim,

said body member having a spherical surface between said annular rims;

a plurality of raised indicia being on said flat circular surfaces, said raised indicia having a height less than the distance between said rims and said flat circular surfaces whereby said rims prevent said indicia from interfering with rolling of said body member on a flat surface;

a dimple formed in said spherical surface, said dimple being concave and being substantially smaller than said indentations so that the statistical chances of said body coming to rest on said dimple are smaller than the chances of coming to rest on one of said indentations.

2. An amusement device according to claim 1 wherein said body member is constructed of a resilient plastic material.

3. An amusement device according to claim 2 wherein said body member is solid in construction.

4. An amusement device according to claim 2 wherein said body member is hollow, the interior thereof being filled with a gaseous fluid.

5. An amusement device according to claim 1 wherein an indicia is engraved in said spherical surface of said body member at a point diametrically opposite said dimple whereby said indicia will be upwardly exposed whenever said body member comes to rest on said dimple.

6. An amusement device according to claim 5 wherein the volume of said dimple is equal to the volume of said engraved indicia so as to balance symmetrically the weight of said body member about the center thereof.
