Abstract
Abstract A three dimensional jigsaw comprised of a plurality of single-layered and multi-layered interlocking puzzle pieces which combine to form, when the puzzle is assembled, a plurality of superimposed, concentric planer layers of differing surface area is disclosed. When the puzzle is properly assembled, a continuous homogenous pictoral illustration is displayed on the surface of each visable planar layer of the puzzle.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
194 words
A self-supporting, three dimensional jigsaw puzzle, comprising: a plurality of first puzzle pieces having a first layer thickness; a plurality of second puzzle pieces having a two layer thickness substantially twice the thickness of said first layer thickness; a plurality of third puzzle pieces having a three layer thickness substantially three times the thickness of said first puzzle pieces; said puzzle pieces being shaped to have interlocking portions, such that each of said pieces interlocks with at least one selected other of said pieces; said second and third pieces each having separate and distinct ones of said interlocking portions disposed at two and three vertically disposed planar layers, respectively, such that said second and third pieces interlock with adjacent pieces at two and three layers of the puzzle, respectively, thereby rigidly coupling the adjacent layers and supporting the entire puzzle; said first, second and third pieces being coupled to one another in a predetermined combination in order to provide a plurality of planar and concentric layers having differing surface areas; whereby a self-supporting three dimensional puzzle having multiple layers is provided by combining and interlocking said single and multi-layered pieces in a predetermined configuration.
Claim 2
Dependent Claim
194 words
A self-supporting, three dimensional jigsaw puzzle, comprising: a plurality of first puzzle pieces having a first layer thickness; a plurality of second puzzle pieces having a two layer thickness substantially twice the thickness of said first layer thickness; a plurality of third puzzle pieces having a three layer thickness substantially three times the thickness of said first puzzle pieces; said puzzle pieces being shaped to have interlocking portions, such that each of said pieces interlocks with at least one selected other of said pieces; said second and third pieces each having separate and distinct ones of said interlocking portions disposed at two and three vertically disposed planar layers, respectively, such that said second and third pieces interlock with adjacent pieces at two and three layers of the puzzle, respectively, thereby rigidly coupling the adjacent layers and supporting the entire puzzle; said first, second and third pieces being coupled to one another in a predetermined combination in order to provide a plurality of planar and concentric layers having differing surface areas; whereby a self-supporting three dimensional puzzle having multiple layers is provided by combining and interlocking said single and multi-layered pieces in a predetermined configuration.
Claim 3
Dependent Claim
26 words
The puzzle as defined by claim 1, wherein said plurality of planar layers displays a continuous and homogeneous pictorial illustration when said puzzle is properly assembled.
Claim 4
Dependent Claim
37 words
The puzzle as defined by claim 2, wherein the bottom-most planar layer is of the greatest surface area, and each succeeding planar layer is concentrically superimposed upon said bottom-most layer and is of increasingly smaller surface area.
