Abstract
Abstract A three-dimensional puzzle comprised of matchable pieces each having a flat base to form a tabular surface when said pieces are matched. The pieces have varying and similar heights and contoured surfaces to generate a sculptured or three-dimensional subject. The puzzle may be in the form of a subject formed from a single aggregation of pieces or may be in the form of connected but independent aggregations of pieces as in the case of connected hemispheres forming a geographic globe structure in relief. The puzzle is further provided with detachable securing means for the locking of the pieces of the solved puzzle and is further provided with additional detachable securing means for connecting aggregations of locked pieces as in a pair of hemispheres as stated.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
181 words
A single-ply puzzle of a desired sculptural subject comprising a plurality of matchable interior and border pieces each including integrally formed three-dimensional face areas to form an overall three-dimensional subject when all of said pieces are assembled, each of said interior and border pieces having a bottom wall for independent support on a tabular surface during assemblage thereon, each of said border pieces having a free border edge wall alignable with the free border edge walls of adjacent border pieces to form several sides of the puzzle when assembled, a securing strip for and to abut the aligned and adjacent free border edge walls of each of the sides of the puzzle as assembled to form an exterior peripheral framework therewith, and slideable interlocking means formed between each of said securing strips and the abutting border edge walls of corresponding sides of the puzzle for locking said assembled puzzle with and inside of said framework and for permitting slideable introduction of each of said strips to said corresponding sides along said tabular surface and without disturbing the assembled puzzle pieces thereon.
