Description

[Detailed description of the invention] This invention relates to a folding magic puzzle in which an arbitrary right-angled isosceles triangle is held by an opponent, and while the person is blindfolded, the pattern that appears on the surface is changed using fold lines. It is something.

To manufacture the product of this invention, proceed as follows.

In other words, points expressed in X-Y rectangular coordinates with the horizontal axis as the X axis and the vertical axis as the Y axis, point AO20, point BO91, and point C1.
,1, point D2,2, point E3,2, point F4゜1, point G5,
1, point H5,0, point ■4,0, point J3.1, point 2,1
, L1,0, and point AO20 are successively connected to cut the cardboard into a shape of 10 consecutive right-angled isosceles triangles as shown in FIG.

Next, use C-L line A, D- as the opening, E-J line C, F-I line 2, respectively, as folding lines, A-C line I, C- as the line, and D- as the fold line.
The -J line is the J-F line, and the F-H line is the virtual line for explanation, and the resulting right-angled isosceles triangle is △A.
BC is △1, △ACL is △2, △CKL is △3, △CD
K is △4, △DJK is △5, △DEJ is △6, △EFJ
is △7, △JFI is △8, △FHI is △9, and △FGH is △10, and the corresponding back sides are △■, foam ■, and △■, respectively.

Bubbles 1. △■, △■, △, △■, △■, △■.

Therefore, FIG. 2 is a state in which FIG. 1 is turned over to the left and right.

Next, △7 at the fold line C. △8. △9. Fold the △10 side to the back side as shown in Figure 3.

Next, △□□□ is placed above △3 as shown in Fig. 4.

Next, fold △1 and △2 overlapping the upper surfaces of △■ and △G as shown in FIG. △2 and △[phase]
, 41 are joined with adhesive.

This is how it was completed, and the back side at this time is as shown in Figure 6.

When playing with the device of this invention, have the other person hold a triangle of your choice and either blindfold or close their eyes.

In this case, the holding position is assumed to be the position marked by △ in △9.

That is, since the situation is as shown in FIG. 7, the player moves from the position of the folding line opening and folding line 2 to △■, △7. △8 to the back side 18
Fold back 0 degrees.

Then, △6 becomes visible, as shown in Figure 8.

Next △6. When the foam book and foam ■ are expanded along fold lines C and A, as shown in Figure 9, the slope is reversed compared to the original shape, and the triangles appearing on the surface are also △9, =n, =1 All other parts have been replaced with separate ones, and the combination of triangles that make up the surface has changed.

At this time, ask them to open their eyes and see if anything has changed, then either blindfold them again or close their eyes, and perform the operation in exactly the opposite way.

In other words, bubbles α are formed on the front side at fold line C and fold line A.
, l, and △3 are folded back and stacked on top of △■ and △10, as shown in Figure 8.Furthermore, hold the △6 part and turn it to the back side at the fold line entrance and the fold line 2 part. When it is rotated and unfolded, the state shown in Fig. 7 is restored.

Then, ask the other party to open their eyes and confirm.

△7 in the puzzle of this invention. △8. Put a pattern in △■, △■, and then add bubbles ■, the lower left half of △■, △■, △3.
Put another pattern of a different color in △10 and 1. a(S)
It is more interesting to not put any symbols in the upper right half of , l and △9 because the changes can be recognized more vividly.

Also, △■, the lower left half of △■, △■, △3. △10 and △
4. △5. If you put a pattern only in △■, bubble 1 and leave the others blank, what was completely white in Figure 7 will change to one in which the main character is the pattern in Figure 9.

The case where the back side is used is shown in FIGS. 10 to 12.

Although the present invention has been explained with reference to the case where two people play with a partner, it is also possible to have fun on your own by constantly looking at the puzzle and coming up with various ideas.

This invention is interesting as a magic puzzle because, as mentioned above, a remarkable change can be obtained with just two operations.
