Jigsaw puzzle

Abstract

A jigsaw puzzle includes a plurality of first pieces, each having a coupling part, and a plurality of second pieces, each having a second coupling part. Each of the first pieces and second pieces is coupled with the corresponding first piece or second piece via the first coupling part and the second coupling part to form a predetermined shape, and each of the second pieces is coupled with the corresponding second piece via the second coupling part to form a 3D structure.

What is claimed is: 
     
         1 . A jigsaw puzzle, comprising:
 a plurality of first pieces, each having a first coupling part; and   a plurality of second pieces, each having a second coupling part,   wherein each of the first pieces and second pieces is coupled with the corresponding first piece or second piece via the first coupling part and the second coupling part, to form a predetermined shape,   wherein each of the second pieces is coupled with the corresponding second piece via the second coupling part, to form a 3D structure.   
     
     
         2 . The jigsaw puzzle of  claim 1 , wherein a sub-image is formed on one face of each of the first pieces and the second pieces, and when each of the first pieces is coupled with each of the second pieces to form the predetermined shape, the sub-images formed on one surface of each of the first pieces and the second pieces is assembled together to form a complete picture. 
     
     
         3 . The jigsaw puzzle of  claim 1 , wherein a part of the second pieces are coupled with the corresponding second piece via the coupling part in a vertical direction. 
     
     
         4 . The jigsaw puzzle of  claim 1 , wherein each of the first pieces and the second pieces is in a geometrical shape, human shape, animal shape or plant shape. 
     
     
         5 . The jigsaw puzzle of  claim 1 , wherein the predetermined shape is in a geometrical shape, human shape, animal shape or plant shape.
