Abstract (en)
[origin: WO2010043395A1] The invention relates to a three-dimensional, self-supporting jigsaw puzzle, having a plurality of puzzle pieces (10) resulting in a hollow body in the assembled state, each puzzle piece having an upper face (12) associated with the exterior of the hollow body, a lower face (14) associated with the interior of the hollow body, an edge (16) extending between the upper face and the lower face, and at least one connecting area (18) extending from the edge (16) in the form of a recess (20) or an extension (22). In order to improve the puzzle assemblability and overall quality, for every two adjoining puzzle pieces (10), the course of the mutually facing edges (16) of the adjoining puzzle pieces (10) is determined between the upper face (12) and the lower face (14) by the bisector (?) of a dihedral angle (?) that is formed between two straight lines (a, ß), which intersect on the bisector (?) and which extend from an upper end point of one of the related edges (16) of the two adjoining puzzle pieces (10) facing each other to an upper end point of an opposite edge of the same puzzle piece, or, in the case of a puzzle piece having a convexly curved surface, to a first maximum (32) in the direction of an opposite edge of the same puzzle piece, and in the connecting region (18) the circumference of the edge (36) of each extension (22) is slightly smaller than the circumference of an edge (38) of a recess (20) in an adjoining puzzle piece corresponding to a respective extension.
