Pinkham Assistant Examiner-Harry G. Strappello [57] ABSTRACT A clear plastic housing contains a plurality of like spherical balls. The housing takes the form of a plurality of concentric spherical shells that are connected together by a plurality of radially extending partitions. The partitions divide the volume between any two neighboring shells into a plurality of arcuate volumes with like radii of curvature and like radial thickness. Each shell that is surrounded by a larger shell bears a plurality of like circular holes in its surface, to connect neighboring volumes in sequence to the spherical volume inside the smallest shell. The diameter of each ball is smaller than the diameter of any holes.

2 Claims, 2 Drawing Figures PUZZLE TOY SUMMARY OF THE INVENTION BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows the invention in use. FIG. 2 shows a cross-section of the invention.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS A plurality of hollow spherical shells are concentrically disposed at regular radial intervals between the smallest inner shell and the largest outer shell-30. The shells are held together by radially extending partitions 40 that extend between shells 20 and and divide the volume between any two neighboring shells into a plurality of arcuate volumes 50 that have the same thickness and radius of curvature. Like circular holes 60 in the surfaces of the shells 10 connect neigh- 2 boring annular volumes together in a sequence that eventually communicates with the central circular volume inside shell 20. The shells and partitions are made of clear plastic and form a housing.

Inside the housing is disposed a plurality of like spherical balls that are smaller in diameter than the holes. The various volumes inside the housing thus form a maze through which the balls may be rolled along preselected routes by manipulating the housing.

While the invention has been described with detailed reference to the drawings, the protection sought is to be limited only by the terms of the claims which follow.

I claim:

1. A toy, comprising:

a housing taking the form of a plurality of hollow spherical shells concentrically disposed and connected together by a plurality of radially extending partitions that block off the volume between any two neighboring shells into a plurality of arcuate volumesof like radii of curvature and like radial thickness with each shell that is surrounded by a larger shell bearing a plurality of like circular holes of clear plastic.
