Abstract
A three dimensional puzzle or toy, of the type sold under the registered trademark RUBIK'S CUBE, in which eight outer bodies or blocks are rotated four at a time about any one of three axes, so that different shapes may be presented in different combinations of said outer bodies. The outer bodies present a desired shape, such as an egg, sphere, clown's head or other desired shape only when the outer bodies are in proper combination. The outer bodies revolve about a spherical core, and are releasably maintained assembled about said core by magnetic means on the adjoining surfaces of the outer bodies.
Claims1
A three dimensional combination puzzle comprising
- a spherical core,
- eight outer bodies each having a spherical inner surface movable over said core, three adjoining surfaces and an outer surface,
- said adjoining surfaces mutually perpendicular to each other and defining planes of rotation intersecting at the center of said speherical core,
- means associated with said adjoining surfaces releasably maintaining said outer bodies assembled about said core, and enabling said outer bodies to be rotated in sets of four about said core,
- said outer surfaces forming a cube when said outer bodies are in proper combination and a plurality of said adjoining surfaces are not parallel to the faces of said cube.
