Description

The present invention relates to a three-dimensional puzzle in which a plurality of three-dimensional pieces (blocks) having different shapes are combined to form a three-dimensional shape such as a cube.

Conventional educational toys such as building blocks, block toys, and three-dimensional puzzles are mainly those that combine multiple solids of various shapes and stack them to form an unlimited shape, a fixed shape, or a convex part. There are those that can connect multiple solids of one or more types of shapes by providing recesses, those that can be combined or assembled by the structure of the shape itself, and those that can be joined by magnetic force.

In addition, conventional building blocks toys are generally those that combine and join in a specific space due to various different shapes and changes in the length of the union side, and those that combine different forms of building blocks or jigsaw puzzles for the user. There are things that derive creativity and spatial cognitive ability.

However, these general building blocks or three-dimensional puzzles can be assembled only in a predetermined combination form, and in many cases, the user has no choice but to make use of his ingenuity to create a unique shape. In addition, these general building blocks or three-dimensional puzzles are not in a shape sufficient to consider the three-dimensional assembly structure in depth, and it is not possible to pursue the so-called difficulty and fun as an adult. In addition, it was not a so-called maniac three-dimensional puzzle that pursued the fun and difficulty peculiar to puzzles or the depth of three-dimensional modeling. Therefore, in order to pursue higher difficulty and fun in educational toys such as building blocks, block toys, and three-dimensional puzzles, various proposals have been made based on the selection documents listed below.

For example, in Patent Document 1 (Japanese Unexamined Patent Publication No. 2018-198912), the block toy is played by combining a plurality of blocks having the same shape, and the entire state in which six cubes are continuous on the same plane is described. It has a substantially U-shape, and one of the two parallel sides of the substantially U-shape has three consecutive cubes, and the other has two consecutive cubes, so that one of the cubes is connected to the other. It is a technical disclosure of a block toy block characterized by having a longer shape.

However, in Patent Document 1, all the blocks have the same shape, and even if these blocks are overlapped and joined together, a cube cannot be formed. Moreover, since all the block shapes are the same, there is a big drawback that the puzzle is not interesting and is just a building block.

Patent Document 2 (Japanese Unexamined Patent Publication No. 2016-87452) includes a connecting portion and a neck portion and a tail portion connected to the connecting portion, respectively, and the neck portion is combined with the neck portion of another building unit to form a neck union structure. Used to form or combine with the tail of another single building to form a successful union structure, the tail being combined with the tail of another single building to form a tail union structure or the neck of another single building. It is used to form the successful union structure in combination with, and to form an annular half-body structure or a columnar semi-body structure with a plurality of other building blocks in the three union forms, and the annular half-body structure and the columnar semi-half The body structure is combined with the tail union structure, the successful union structure and the tail union structure of another annular semifield structure or another columnar semifield structure corresponding to the head union structure, the successful union structure or the tail union structure, respectively. , There is a technical disclosure about an annular pillar or a single building that forms a pillar.

However, the content of Patent Document 2 is merely a so-called building block that creates a three-dimensional object by stacking and joining simple building blocks of the same shape, and is not interesting to form a certain cube, for example. It's also a very simple puzzle. In addition, the shape of each block forming the three-dimensional puzzle is simple and the number is large.

As described above, most of the conventional assembly puzzles are completed by assembling each block and then assembling the next block on the molded body. And even in puzzles that make shapes such as cubes, each block is just pushed in, so if you turn it upside down, it will fall out. In addition, the shape of each block was easy for the puzzle maker to understand, and the finished cube was easy to imagine, so it was a very simple and simple puzzle.

That is, in the above-mentioned Patent Document 1 and Patent Document 2 and the conventional assembly puzzle, the cube is divided into several kinds of constant shapes, the blocks are three-dimensionally superposed, and the following blocks are superposed. Therefore, there was no one that offered the difficulty of temporarily canceling the superposition of the previous blocks and then superimposing them again. Even if the same cube was finally formed, there was no difficult puzzle that pursued extreme difficulty in assembling the puzzle and could not easily associate the final completed form with the shape of each block. Similarly, the difficulty of disassembling the completed cube into individual blocks has the major drawback of lacking in difficulty and fun.

In addition, the above-mentioned Patent Document 1 and Patent Document 2 and the conventional assembling puzzle are simple puzzles or stacks for children whose target age is extremely young to operate and enjoy the puzzles, and can be enjoyed by adults. It can be said that the difficulty level is too low for an advanced puzzle.

JP-A-2018-198912 Japanese Unexamined Patent Publication No. 2016-87452

The present invention is intended to solve such problems in the prior art, and an object of the present invention is to develop and provide an esoteric three-dimensional puzzle that is difficult for adults to assemble, repeats trial and error, and can be enjoyed for a long time. And.

In the present invention, a cube is divided into several types of constant shapes, and the blocks (hereinafter, the blocks are also referred to as "three-dimensional individual pieces") are three-dimensionally superposed, and the following blocks are superposed. Therefore, the purpose is to develop and provide a difficult three-dimensional puzzle that pursues the difficulty as a puzzle, such as temporarily releasing the superposition of the front blocks, superimposing them again, and finally forming a cube. Similarly, even when the completed assembly is disassembled into individual blocks, it is an issue to pursue difficulty and fun and to provide a so-called three-dimensional puzzle that adults can enjoy.

For example, it is a three-dimensional puzzle that is difficult to disassemble, open, assemble, and seal, such as the traditional craft "Karakuri Box" from the Edo period, and each block provides a three-dimensional puzzle with a complicated structure that does not fall out in the middle of the process. Want to. In addition, assembling or disassembling each block such as "Karakuri Box" cannot be done by each block alone, and assembling or disassembling is repeated while moving other blocks to finally assemble or disassemble the cube. The purpose and task is to develop and provide advanced three-dimensional puzzles.

In order to solve such a problem, the three-dimensional puzzle according to the present invention is a three-dimensional puzzle in which a large cube or a large cube is assembled from a plurality of three-dimensional pieces in which a plurality of small cubes are surface-connected in a three-dimensional direction, and the large cube or the above-mentioned large cube or The large cube is a large cube or a large cube formed by the number of the small cubes in the three-dimensional direction of four or more in the vertical direction, four or more in the horizontal direction, and four or more in the height direction. by the formed of a plurality of solid pieces are inside the large cube or the large cuboid a structure having one or a number of the small cubes of the same volume of space, the large cube or a combination of the three-dimensional pieces When forming the large square, since the shapes of one or more three-dimensional pieces are shaped to be locked and combined with each other inside the large cube or the large square , each of the three-dimensional pieces is combined and formed. If so, move the three-dimensional piece of the previous combination upward and / or downward and / or left and / or right and / or forward and / or backward beyond one side length of the small cube. It is characterized in that the shape is such that the next combination of the three-dimensional pieces cannot be inserted unless an insertion space is created inside the large cube or the large square.

Further, in the three-dimensional puzzle according to the present invention, when all the shapes of the three-dimensional pieces are combined to form the large cube or the large rectangular parallelepiped, each other inside the large cube or the large rectangular parallelepiped. Since the shape is locked and combined in a key shape, it is possible to take a mode in which each of the three-dimensional pieces cannot be simply pulled out in one direction from the large cube or the large rectangular parallelepiped.

The three-dimensional puzzle according to the present invention has a structure in which the large cube or the inside of the large rectangular parallelepiped formed from the plurality of three-dimensional pieces has one or more spaces having the same volume as the small cube. When disassembling the large cube or the large rectangular parallelepiped, the shape of one or more of the three-dimensional pieces is a shape in which the large cube or the large rectangular parallelepiped is locked and combined with each other in a key shape inside the large cube or the large rectangular parallelepiped. Since each of the three-dimensional pieces cannot be simply pulled out from the rectangular parallelepiped in one direction, when each of the three-dimensional pieces is disassembled and pulled out, the other three-dimensional pieces are raised above one side length of the small cube. Each solid piece unless a drawing space is created inside the large cube or rectangular parallelepiped by moving it in the direction and / or downward and / or left and / or right and / or forward and / or backward. It is also characterized by its shape that cannot be disassembled and pulled out.

When each of the three-dimensional pieces of the three-dimensional puzzle according to the present invention is combined so as to form a large cube or a large rectangular parallelepiped, the three-dimensional pieces are combined by hooking each other inside the large cube or the large rectangular parallelepiped. Has a shape that can be used.

That is, the shape forming the inside of the large cube of each three-dimensional piece of the three-dimensional puzzle according to the present invention has a shape in which the three-dimensional pieces are locked and combined with each other in a key shape. Therefore, for example, the large cube. Even in the middle of combining, each three-dimensional piece is fixed, and each three-dimensional piece does not fall off naturally even if it is held upside down or slanted. Hereinafter, since the three-dimensional puzzle that forms a large rectangular parallelepiped is the same as the puzzle that forms a large cube, it will be described as a three-dimensional puzzle that forms a large cube.

The shape in which the three-dimensional pieces of the three-dimensional puzzle according to the present invention are locked and combined in a key shape is the same volume as the small cube inside the large cube when combined so as to form the large cube. It is formed by having a structure in which one or more spaces of the above are formed.

That is, the shape forming the inside of the large cube of each three-dimensional piece of the three-dimensional puzzle according to the present invention has a shape in which the three-dimensional pieces are locked and combined with each other in a key shape. In assembling, when assembling and inserting one three-dimensional piece, it cannot be easily inserted. One or more three-dimensional pieces of the combination before assembling and inserting the three-dimensional pieces are placed upward and / or downward and / or leftward and / or rightward and / or forward and / or rearward over one side length of the small cube. The shape is such that the next three-dimensional piece cannot be combined and inserted unless it is moved and an insertion space is created inside.

Similarly, the shape forming the inside of the large cube of each three-dimensional piece of the three-dimensional puzzle according to the present invention has a shape in which the three-dimensional pieces are locked and combined with each other in a key shape. Even in the disassembly into each three-dimensional piece, when one three-dimensional piece is taken out, it cannot be easily taken out. Move one or more three-dimensional pieces of other three-dimensional pieces upward and / or downward and / or leftward and / or rightward and / or forward and / or rearward over one side length of a small cube, and extract them inside. It is a shape that cannot be extracted for dismantling unless a space is created for it.

As described above, the three-dimensional puzzle according to the present invention has each three-dimensional individual piece alone in assembling or disassembling each three-dimensional individual piece (may be expressed as a block) like the "karakuri box" which is a traditional Japanese technique. It is an advanced and difficult three-dimensional puzzle that cannot be inserted or pulled out, and the large cube is finally assembled or disassembled by repeating assembling or disassembling and extracting while moving other three-dimensional pieces by a certain dimension.

Next, in order to explain the above concept of the three-dimensional puzzle according to the present invention, individual examples of the three-dimensional puzzle according to the present invention will be described while showing a specific shape.

First, as the simplest individual case, the number of small cubes formed from two-dimensional pieces in the three-dimensional direction is four in the vertical direction, four in the horizontal direction, and four in the height direction (hereinafter, three-dimensional). A three-dimensional puzzle according to the present invention of a large cube in which the number in the direction is four in the vertical direction, four in the horizontal direction, and four in the height direction are described as "4 * 4 * 4"). Will be described. Further, this individual case will be referred to as "Case 1 (4 * 4 * 4, 2 solid piece)" hereafter.

In the case 1 (4 * 4 * 4, two-dimensional piece) of the three-dimensional puzzle according to the present invention, specifically, the number of the large cube in the three-dimensional direction of the small cube is 4 * 4 * 4. It is a large cube formed of pieces and shown in FIGS. 57 and 58. In the large cube, the three-dimensional individual pieces are the X pieces shown in FIGS. 59, 60 and 61, and the three-dimensional individual pieces are shown in FIGS. 59 and 59. It is also possible to take an embodiment consisting of the Y pieces shown in 62 and FIG. 63.

Describe the description method of all drawings. In all drawings, the front surface on the left side is defined as the front surface (front surface), and the perspective view is described as a perspective view viewed from the upper right direction. The six views in all the drawings have the front view in the center, the plan view (top view) above it, the rear view above the plan view, the bottom view below the front view, and the right side of the front view. The left side view is shown on the left side of the right side view and the front view. In addition, in all drawings, the portion where the solid is hollow is shown in black.

As described above, in Case 1 (4 * 4 * 4, 2 three-dimensional pieces) of the three-dimensional puzzle according to the present invention, as described above, the shapes of the X and Y three-dimensional pieces are different from each other. Since it has a shape that can be hooked and combined like a key, each solid piece is fixed even while the large cube is being combined or disassembled, and even if it is held upside down, it is diagonal. Even so, each three-dimensional piece does not fall off naturally.

Next, as an individual example, a large cube in which the number of small cubes formed from two-dimensional pieces in the three-dimensional direction is four in the vertical direction, four in the horizontal direction, and four in the height direction. A three-dimensional puzzle according to the present invention having a space equivalent to one small cube inside will be described.

The three-dimensional pieces are the W pieces shown in FIGS. 66 and 67, and the three-dimensional pieces are shown in FIGS. 68 and 68. It can take an embodiment consisting of the Z pieces shown in 69.

As described above, in the case 9 (4 * 4 * 4, 2 three-dimensional piece, space 1) of the three-dimensional puzzle according to the present invention, as described above, in the assembled shape, the shapes of the W and Z three-dimensional pieces are formed. However, since each three-dimensional piece has a shape in which each three-dimensional piece is locked and combined in a key shape, each three-dimensional piece is fixed, and each three-dimensional piece is naturally held upside down or at an angle. Will not fall out.

In addition, Case 9 (4 * 4 * 4, 2 solid pieces, space 1) of the three-dimensional puzzle according to the present invention has the same volume as a small cube inside in a shape assembled by W and Z solid pieces. It is a structure in which one space is formed. By having the space for one small cube, it is possible to form a shape in which each three-dimensional piece is locked and combined in a key shape, and each three-dimensional piece is fixed and can be slanted even if it is held upside down. However, each three-dimensional piece does not fall off naturally. That is, Case 9 is the case of the simplest shape of the present invention as in Case 1 (4 * 4 * 4, 2 solid pieces). However, the difference from Case 1 is that it has a space for only one small cube inside. So to speak, this is a case that proves claim 1.
