Description

  The present invention relates to a stacked 3D (three-dimensional) jigsaw puzzle, and more particularly, to a stacked three-dimensional jigsaw puzzle including a plurality of pieces that are superposed to form a three-dimensional structure.

  A conventional planar jigsaw puzzle is composed of a plurality of small pieces each having a plurality of protrusions and cutouts. Two adjacent small pieces are connected to each other with the protrusion and the notch. Therefore, a complete picture is formed little by little. The difficulty of a jigsaw puzzle depends on the number of pieces it contains. This kind of jigsaw puzzle is a little limited in charm, but it gives fun to the player. In order to increase the fun of jigsaw puzzles, 3D jigsaw puzzles have been introduced to the market, challenging the patience and skill of the players.

  The three-dimensional jigsaw puzzle includes a plurality of pieces and may include an air bag. When the three-dimensional jigsaw puzzle includes an air bag, the player can place each piece on the outer periphery of the air bag and connect all two adjacent pieces according to the spherical outline of the air bag. If there is no air bag in the 3D jigsaw puzzle, the player will have to rely on his own skills to gradually form the 3D pattern.

  Whatever kind of jig jigsaw is used, the pieces are connected to each other by a plane or a curved surface. In other words, the space uses are limited and fixed, so there is little challenge for the patience and skill of the player. To overcome this disadvantage, the present invention provides a stacked three-dimensional jigsaw puzzle that alleviates the above problems.

  The main object of the present invention is to provide a stacked 3D jigsaw puzzle that provides an unlimited space shape so that different heights and shapes are shown after the 3D jigsaw puzzle is completed.

  Another object of the present invention is that each piece is stacked on top of another piece and a stacked three-dimensional jigsaw puzzle is created by stacking the pieces.

  Still another object of the present invention is to provide each piece with a boss formed on the top surface and a recess formed on the bottom surface, so that the recess and the boss are maintained so that the strength and durability of the piece are maintained. It is not aligned.

  Other objects, advantages and novel features of the present invention will become more apparent from the following description with reference to the accompanying drawings.

  Referring to FIGS. 1 and 2, a stacked three-dimensional jigsaw puzzle 1 according to the present invention includes a plurality of small pieces 11. Each small piece includes a plurality of bosses 110 formed on the top surface and a plurality of recesses 111 formed on the bottom surface. Is provided.

  Referring to FIGS. 3 and 4, each piece 11 is hollow, and the boss 110 corresponds to the recess 111 of the adjacent piece 11 so as to be received in the recess 111 of the adjacent piece 11. Since the two adjacent pieces are different in size, a three-dimensional pattern, ie a castle, is formed after the boss 110 is received in the corresponding recess 111. Further, the boss 110 is not aligned with the recess 111 of the same small piece 11 in order not to weaken the rigidity of the small piece 11.

  Referring to FIGS. 5 and 6, another three-dimensional jigsaw puzzle 2, i.e. a snowman, is shown and has a plurality of pieces 21. Each small piece 21 has a plurality of bosses 210 formed on the top surface thereof and a recess 211 not aligned with the bosses 210 formed on the bottom surface thereof. The boss 210 corresponds to the recess 211 of the adjacent small piece 21 so that the boss 210 is received in the recess 211 of the adjacent small piece 21. Depending on the size of the small pieces 21, a three-dimensional pattern is formed after the small pieces 21 are assembled.

  Although numerous features and advantages of the present invention have been described in conjunction with details of construction and function, these are merely exemplary, and in detail, particularly within the scope of the principles of the invention, such as shape, size, placement of parts, etc. Changes may be made within the broad general meaning of the terms in which the claims are expressed.

The perspective view of the jigsaw puzzle of this invention comprised as a castle. The perspective view which decomposes | disassembles and shows a part of jigsaw puzzle of this invention. The expansion perspective view of two small pieces in the jigsaw puzzle of FIG. Schematic which shows the mutual relationship between small pieces. A front view of a three-dimensional jigsaw puzzle configured as a snowman. The figure which decomposes | disassembles and shows a part of Example of FIG.

Claims (3)

  A stacked three-dimensional jigsaw puzzle that includes a plurality of pieces that are superposed to be combinable with each other, each piece having a different size from the other pieces.   Each piece has a plurality of bosses formed on the upper surface thereof and a plurality of recesses formed on the bottom surface thereof, the recesses corresponding to the bosses of adjacent pieces, and the bosses are adjacent to each other. The stacked three-dimensional jigsaw puzzle according to claim 1, which is received in the recess of the small piece to form a three-dimensional pattern.   The stacked three-dimensional jigsaw puzzle according to claim 2, wherein the boss and the recess of the same piece are not aligned with each other.
