Three-Dimensional Jigsaw Puzzle

Abstract

A three-dimensional jigsaw puzzle consisting of one or more two-dimensional puzzle parts, each consisting of two or more jigsaw puzzle pieces. The puzzle parts can interconnect using leg and hole connectors to form the three-dimensional object. Each puzzle part is fixed using fixing sheets which are precut to match the format of its corresponding puzzle part. Each puzzle part can have puzzle pieces which can be bent to create corners. The bending is achieved by applying a reinforced tape along the bending line on the inner side, and by having a straight cut on the outer side of the corner penetrating the cut through the puzzle piece, but without cutting the tape. The puzzle pieces are laminated with paper that can bear an image on both sides. The puzzle parts can have a reinforcement bar glued on the non-visible side so that they retain the desired planar shape.

11 . A jigsaw puzzle game for assembly of a three-dimensional object comprising: one or more two-dimensional puzzle parts which connect to one another to form said three-dimensional object;
 each said two-dimensional puzzle part comprising two or more jigsaw puzzle pieces;   each said jigsaw puzzle piece comprising a core of cardboard and a laminated printed paper bearing an image applied to a visible side of the cardboard;   at least one of the jigsaw puzzle pieces comprising a bending line to permit bending to form a bending corner;   wherein the bending line is achieved by providing a fiber-reinforced adhesive tape applied directly to the cardboard core on an inner side of the bending corner and along the bending line and laminating the puzzle piece by gluing the printed paper over both the fiber-reinforced adhesive tape and the cardboard and making a straight line cut on an outer side of the bending corner, wherein the straight line cut penetrates through the cardboard but not through the said fiber-reinforced adhesive tape so that once the jigsaw puzzle piece is bent, the fiber-reinforced adhesive tape holds together the two sides of the bent jigsaw puzzle.   
     
     
         12 . The jigsaw puzzle game for assembly of  claim 11 , wherein at least one of the said jigsaw puzzle pieces having connecting shapes consisting of straight or L-shaped protrusions wherein the connecting shapes extend beyond the contour shape of the said two-dimensional puzzle parts of claim  1  to connect to a hole of another two-dimensional puzzle part to form the three-dimensional object; 
     
     
         13 . The jigsaw puzzle game for assembly of  claim 11 , wherein the said jigsaw puzzle pieces that form the said two-dimensional puzzle parts are fixed with flexible adhesive fixing sheets; each said flexible adhesive fixing sheet comprising a thin flexible sheet manufactured from paper or plastic materials and is coated with adhesive on one side and has a protective backing layer to cover the adhesive, and that said backing layer is removable, to allow the flexible adhesive fixing sheet to be fixedly placed on the said two-dimensional puzzle parts from claim  1  in order for the said jigsaw puzzle pieces of the said two-dimensional puzzle parts to remain assembled; 
     
     
         14 . The jigsaw puzzle game for assembly of  claim 11 , wherein the said two-dimensional puzzle parts of  claim 11  have at least one reinforcement bar to help the said two-dimensional puzzle parts to maintain a desired planar shape; each said reinforcement bar comprising a strip of rigid material such as plastic or cardboard with self-adhesive applied on one side so that the said bars can be fixed to the said two-dimensional puzzle parts.
