Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a regular hexagonal folding puzzle whose surface design/pattern can be sequentially and repeatedly changed into three types by repeating a predetermined operation.

The product of the present invention can be manufactured as follows. That is, as shown in Figure 1, 10 equilateral triangles with one side of A are connected alternately with their hypotenuses, and an equilateral triangle with one side of A is connected to the base of the equilateral triangle on the right end of the strip. Prepare a folding puzzle sheet in which the bases of equilateral triangles with side A are connected, and divide each equilateral triangle of this folding puzzle sheet into 1, 2, 3, ..., 11, 12 from the left end.
shall be. Here, the procedure for manufacturing a regular hexagonal folding puzzle according to the present invention from a folding puzzle sheet having 12 regular triangles as shown in FIG. 1 will be explained using explanatory diagrams.

The broken lines at the boundaries of equilateral triangle 1 and equilateral triangle 2, equilateral triangle 2 and equilateral triangle 3, ..., equilateral triangle 10 and equilateral triangle 11, and equilateral triangle 11 and equilateral triangle 12 are respectively a, b, ..., j, k. Sometimes, this folding puzzle sheet is folded 180 degrees along the fold line e so that the surfaces of the equilateral triangles 5 and 6 meet [the state shown in Figure 2 a], and then folded along the fold line h to form the equilateral triangle 8. Fold it 180 degrees so that the back sides of equilateral triangle 9 meet each other [as shown in Figure 2 b], then fold it at fold line b so that the back sides of equilateral triangle 2 and equilateral triangle 3 meet each other.
Fold 180° [state shown in Figure 2 c], then go through the state shown in Figure 2 d to the side where the back sides of equilateral triangles 10 and 11 meet at the fold line j, and then go to the state shown in Figure 2 e.
Fold back 180°, then create an equilateral triangle 1 at the fold line k.
So that the surfaces of 1 and equilateral triangle 12 meet each other.
It is then folded back 180 degrees and the back side of equilateral triangle 12 and the back side of equilateral triangle 1 are glued together to complete the state shown in Figure 2 f. The regular hexagonal folding puzzle according to the present invention has now been completed.Next, a method for playing with it will be explained with reference to FIG. In the drawings, , . . . represent the back surfaces of equilateral triangle 1, equilateral triangle 2, .

When playing the regular hexagonal folding puzzle according to the present invention, from the state shown in FIG. 10, make the boundaries of equilateral triangles 3 and 4, equilateral triangles and equilateral triangles, and equilateral triangles 9 and 10, make valley folds, and align the valley-folded boundaries at the center. Fig. 3c], in this state, the upper end of the valley-folded boundary is opened radially with the lower end still attached [Fig. 3d], and the protruding equilateral triangle or the equilateral triangle between and 12 becomes the surface. Fold it like this [3rd
Figure e]. Through this operation, the surface of the regular hexagonal folding puzzle according to the present invention becomes regular triangles 3, 4,
, 9, 10 changes to a regular hexagon consisting of regular triangles 5, 6, , , . By repeating the same operation, a regular hexagon consisting of regular triangles 2, , 7, 8, and 11 can also be obtained. In this way, if a uniform design or pattern is drawn on the surface of each regular triangle of the regular hexagon that appears on the surface, the surface will change sequentially with the simple operation described above, making it interesting. During the above operation,
In the case of Figure 3e, if a design/pattern similar to the design/pattern drawn on the equilateral triangle and/or faces is drawn as a dummy on the faces of the equilateral triangle and/or and 12, then it is considered to be an equilateral triangle. Since there is a protruding equilateral triangle 12 that can be folded to either side in between, there is a high possibility of folding in the wrong direction, and as a result, it is difficult to make the design/pattern appear repeatedly with simple operations, making it difficult to understand. It increases.

As described in detail above, the regular hexagonal folding puzzle according to the present invention is a regular hexagonal folding puzzle consisting of six equilateral triangles. By valley-folding and mountain-folding every other boundary, the designs and patterns on the surface can be sequentially changed.
In the process of the appearance of three types of designs/patterns, a protruding equilateral triangle that is always folded once in any direction is generated, which has the advantage of eliminating monotony and creating confusion, making it interesting, and also having the advantage of being enjoyed both from the front and the back. Furthermore, it has the advantage that it can be easily manufactured from inexpensively available cardboard, etc., and its commercial value is extremely high.
