Description

[Detailed explanation of the invention] This invention is achieved by appropriately reversing the small blocks.
It is about toys that allow you to enjoy changing shapes and colors.

The basic principle of the present invention will be explained with reference to Figs. 1 to 15. First, as shown in Figs. 1 and 2, small cubes 1a to 1h with the same side length are
It is well known that one large cube 1 is formed by combining the pieces. In other words, if one large cube is divided, eight small cubes will be obtained.

Therefore, if we look at the relationship between the faces of large cube 1 and small cubes 1a to 1h, we can see that in each of the eight small cubes, which are regular hexahedrons, three half of the six faces are visible from the outside, and the remaining three faces are visible from the outside. is inside and cannot be seen from the outside. This means that the large cube 1
This means that the same number of faces as the 3 faces of each of the 8 regular hexahedrons that form the 6 faces of 24 faces are hidden inside.

Next, these eight small cubes 1a to 1h are connected by the known connection method shown in FIG. 3 (Japanese Patent Publication No. 45-2546, Utility Model Application No. 53-3696). That is, each small cube 1
Of the 12 sides a to 1h, only two sides that are not adjacent but orthogonal are bendably connected to the other sides of the cube. As a result, when each of the small cubes 1a to 1h is inverted in accordance with the procedure shown in FIGS. 4 to 8, the surfaces hidden on the inside will be exposed on the outside.

By the way, let us examine the movement of such small cubes 1a to 1h by focusing only on the edges (edges) of each cube. Then, each small cube 1a~1
It can be seen that h does not necessarily have to be a regular hexahedron, but may be a cube having the relationship of sides as shown in FIG. 9 (hatched area in the figure). Figure 10 shows an example of the most extreme three-dimensional structure. Eight of these three-dimensional bodies are connected in the same relationship as shown in Figure 3, and operated as shown in Figures 11 to 15. You can understand that the front and back sides are completely interchangeable.

The present invention utilizes the principle of flipping the eight cubes connected in the above-described manner, and extracts the minimum required structure of each cube by focusing only on the movement of the sides (indicated by the shaded area in Figure 9). In addition to creating a solid with a specific structure, that is, a solid that can become a star-like rhombic dodecahedron when inverted after connection, eight of these solids were connected as described above, and colors, patterns, and shapes were created based on the This is a toy designed to allow you to enjoy changes.

FIG. 16 is an embodiment of the present invention, and shows an example of a solid having the side relationship shown in FIG. 9 above. That is, this solid 10 is made of solid soft plastic, and has three diagonal lines 12a, 12b, 1 passing from the six vertices of the cube to the midpoint 11.
2c. The solid obtained by this has square surfaces 14a, 14b, 14c that are orthogonal to each other, and 6 that has an uneven shape.
three triangular surfaces 13a, 13b, 13c, 13d,
13e and 13f.

In the present invention, eight such solid bodies 10 are prepared, and two non-adjacent but orthogonal sides of each solid body 10 are sequentially connected to other solid bodies in the manner shown in FIG. For this connection, for example, adhesive tape or the like may be used.

17 to 20 show changes in the shape of one block constituted by the solid body 10 described above. That is, each solid body 10 becomes a large cube as shown in FIG. 17 by orthogonal square surfaces 14a, 14b, and 14c facing outward. From this state, if each solid is reversed in the direction of the arrows in Figures 18 and 19, the shape changes as shown in the figures, and in the end, the faces that were hidden inside when it was a large cube are turned outside. This results in a star-shaped rhombic dodecahedron as shown in Figure 20. In this case, each triangular surface 13a...13d
By color-coding them in an orderly manner, you can enjoy the changes in color patterns.

On the other hand, as another embodiment of the present invention, by preparing two sets of blocks constituted by the solid body 10, even more various changes can be obtained. That is, the two blocks have similar shapes to each other, and when one set of solids 10 is taken and fitted together,
They are in a cubic relationship. Therefore, when the solid bodies 10 of the two blocks are fitted together,
This results in eight small cubes as shown in Figure 3. Therefore, the orthogonal square surfaces 14a, 14b, 1 of each solid body 10
4c, for example, the square faces 14a, 14b, 14c of each solid that constitute one block are white,
Square surface 14 of each solid that constitutes the other block
Let a, 14b, and 14c be red. and the fourth
By inverting a small cube made up of a set of solids 10 according to the procedure shown in FIGS. 8 to 8, it is possible to change the color appearing on the outer surface of the large cube from red to white or vice versa.

In addition, in the present invention, in order to color code each side, for example, color adhesive tape or the like may be used.

According to the present invention explained above, by inverting the three-dimensional objects that make up the block, you can enjoy changes in shape, color, and pattern, and since it is made of soft plastic, the corners are not sharp. However, there is no need to worry about injury. Furthermore, the present invention has the advantage that it can be mass-produced easily and at low cost because it only involves manufacturing a large number of solid bodies of the same shape.
