US 6,601,849 B1 · Golf ball spherical puzzle

Abstract

A multiple piece puzzle comprises a solid sphere with the external appearance of a golf ball of modern construction. A series of curving cuts through the sphere separate the sphere into a plurality of separate pieces wherein the cuts form complementary pairs of surfaces among the separate pieces. Proper assembly of the pieces solves the puzzle and restores the golf ball appearance of the puzzle. The curving cuts form interlocks between the pairs of complementary surfaces whereby, once assembled, the sphere will be retained together in three dimensions in a similar manner as two-dimensional puzzle pieces are retained together. In the preferred embodiment, the puzzle comprises eight pieces that can slide together, however, the puzzle can be formed with more pieces for added complexity and more challenge.

Dependent claims

A puzzle comprising:

an even number of separable non-identical pieces each having only one exterior surface forming a portion of the surface of a sphere and other surfaces each complementary to a surface on another piece of the puzzle,
the complementary surfaces each including at least one curving surface cut resembling the curving undercut of a two-dimensional puzzle, and formed of straight line elements defining an interlock means for preventing lateral separation of two of the pieces when engaged together,
the straight line elements of each curving surface of the complementary surfaces being generally perpendicular to the straight line elements of each of the other complementary surfaces,
the plurality of separable pieces, upon engagement of all of the complementary surfaces, forming a sphere and interlocking so as to maintain engagement in the form of the sphere.
