Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention relates to a puzzle, and more specifically, it is a very difficult level from a relatively simple level. It's about cheap and very interesting puzzles that you can create up to a bell freely.

[0002]

[Prior art]

  Conventionally, a picture is drawn on thick paper, etc. As a toy, puzzles that arrange the pieces one by one and restore the original picture are widely used as toys. There is.

[0003]

[Problems that the device is trying to solve]

  The above-mentioned conventional puzzle is for children, it is interesting at first, but the arrangement order is remembered There is a problem that it becomes uninteresting and I get tired of it, and it is not for children other than It is not the target of mari play.   Therefore, the purpose of the present invention is to solve puzzles from a relatively easy level to an extremely difficult level. Is to provide a technology that can be easily provided.

[0004]

[Means for solving problems]

  The above object is achieved by the present invention described below. That is, the present invention has a length of one side If it is a square plate-like body that is X and its vertices are A, B, C and D, then AB A point at a distance from the A point on the side represented by the following formula is defined as a point, and an intermediate point on the BC side is b point. And the point at the distance from the C point on the CD side expressed by the following formula as the c point The point between points is d point, and the point where a straight line orthogonal to the midpoint of the line ad intersects the line bc is called point e. Then, the square plate shape is cut into bc line, ae line and de line and divided into four parts. It is a featured puzzle.

[Formula 2]

[0005]

[Action]

  The square shown in FIG. 2a is cut by a line (broken line) connecting the specific points as described above. this 2b can be disassembled as shown in Fig. 2b and then rearranged into the original squares as shown in Fig. 2c. I can. Further, as shown in FIG. 3a, the four pieces are separated as in FIG. It can be rearranged into a regular triangle. In this example, both adults and children spend some time Complete by hanging, but at least one of the four pieces, eg four, as shown in Figure 4a. After cutting each with an arbitrary line, separate them and rearrange them into squares or equilateral triangles in the same way. However, it is difficult to rearrange them into squares and equilateral triangles. Absent.   Therefore, one of the four pieces, two pieces, three pieces, four pieces, and at least one or more of the four pieces. Cut the top with an arbitrary line and divide it into two, and as the number of cut pieces increases, it becomes easier It can be a difficult puzzle that is difficult to complete, even if it takes several hours. Of course Arranged by dividing one or more of the four pieces into three, four, ... The difficulty of replacement increases geometrically according to the number of divisions.

【Example】

  The present invention will be described in more detail with reference to the preferred embodiments shown in the drawings.   FIG. 1 is a diagram for explaining an example of a method for creating a puzzle of the present invention. Used here The material to be used is paper, cardboard, metal plate, plus Any material such as a tick sheet may be used.   First, a square plate-shaped body, one piece of which is X in length, is prepared. The side length X is arbitrary However, it is usually about 3 cm to 50 cm. In the example of Fig. 1, the length of one piece is 100m. m is an example. Points a to e are created on each side of the plate. Is point a apex A? Is the point expressed by the following formula, point b is the midpoint of side BC, and point c is the peak. The distance from the point C is represented by the following formula, the point d is the midpoint of the side DA, and e The point is the midpoint of the line ad at which a straight line intersecting with the line bc intersects.

[Formula 3] In the above equation, when X is 100 mm, the distance between Aa and Cc is about 57.2 mm, the distance between Bb and Dd is 50 mm, and the length of the line ce is And the length of the line eb is represented by the following formula.

[Formula 4] Note that the method of calculating the above equation is extremely complicated and difficult to understand, so its explanation is omitted in this specification.

[0007]   Next, the square-shaped body is cut along the lines bc, ae, and de in any order and the pattern of the present invention is cut. The basic form of cheating is completed. The four pieces cut as described above are as shown in FIGS. 2 and 3. Can be rearranged into either the original square or an equilateral triangle of the same area as the square. I can.   In the example of FIG. 4, each of the four pieces cut in FIG. 1 is cut by an arbitrary line and divided into two. This is an example of how to disassemble these 8 pieces into the original squares and regular triangles. Is quite difficult, and depending on the person, it takes several to tens of hours to complete Will   Although the above examples have been described based on the square plate-shaped body, the original plate-shaped body is an equilateral triangle. Even if it is, if it is cut according to the same principle as in the case of a square, it will be divided into four pieces of the same shape. What you can do is self-evident.   On the front and / or back of each square plate or cut piece used in the above, When the same or different coloring and / or the same or different patterns are printed respectively Is more preferable as a toy, and the color, pattern, and printing differ between square and equilateral triangles. When the pieces are divided into squares and rearranged into equilateral triangles. If the printed pattern changes in some way when It can be a white puzzle.

[0008]

[Effect of device]

  According to the present invention as described above, the power level from a relatively easy level to an extremely difficult level is The cheats can be created easily and freely.
