Description

[Detailed explanation of the idea] This invention relates to the improvement of jigsaw puzzles.

A jigsaw puzzle is a puzzle that consists of many pieces of the same shape except for the corners and edges, and when these pieces are fitted together in an orderly manner, a uniform pattern is formed on the surface of each piece. The criterion for correctness or failure is the relationship with the pattern on the surface of each piece, so the more unclear and mutually confusing patterns there are, the more difficult it becomes to find the relationship between the pieces.

In general, the larger the number of pieces, the more similar and confusing patterns there will be.As a result, the accuracy of fitting will be lower, and it will take more time to complete. people tend to avoid jigsaw puzzles.

The purpose of this invention is to enable intermediate, non-final, mutual positioning of each piece with respect to the overall unified design, even for large jigsaw puzzles with a large number of pieces. To create and provide a jigsaw puzzle that allows even younger people to complete the fitting of large jigsaw puzzles based on positioning.

In order to achieve the above-mentioned purpose, the jigsaw puzzle according to this invention has a large number of pieces, each of which has a different pattern written on its surface that is related to all of the pieces in a unified manner, and each of the pieces has a number of pieces. On the back side, there is a common mark (mark) for each division that can be roughly divided into multiple parts of the entire puzzle surface.
Consists of those listed.

The configuration of this invention will be explained in detail below using figures.

Each of the embodiments shown in FIGS. 1 and 2 shows the back side of the entire jigsaw puzzle in which the pieces 5, 5, 5, . . . have been correctly arranged.

In Figure 1, each piece of the jigsaw puzzle is divided into 8 sections of equal area, i.e.
It is equally divided into A2, A3, A4, B1, B2, B3, and B4, and the boundary 8 between the sections A and B is the upper and lower edge lines 9 and 10 of the jigsaw puzzle. parallel boundaries 11, 1 between said sections 1, 2, 3, 4;
2 and 13 are provided parallel to the left and right edge lines 14 and 15 of the jigsaw puzzle, and the uppercase letter A of the alphabet is printed on the back side of all the pieces in section A1, and similarly, B is printed on section A1. ,
C is printed on section A2, D on section B2, E on section A3, F on section B3, G on section A4, and H on section B4.

Therefore, when starting to fit together a jigsaw puzzle, first, each piece is roughly sorted based on the printing letters A to H, and the pieces are fitted in each section to complete the arrangement within each section. Finally, by connecting each section, even large jigsaw puzzles can be completed relatively easily.

However, the positioning of each piece within the same division is not determined by the above-mentioned character division, but is determined based on the pattern (not shown) on the surface of each piece as before.

In the embodiment shown in FIG. 2, all the pieces can be roughly sorted based on four divisions C, D, E and F divided by two diagonal lines 6 and 7, and the back side of each piece in the division C is A ○ mark is printed on all of them, and similarly, a △ mark is printed in section D, a □ mark is printed in section E, and an x mark is printed in section H.

However, since the pieces on the two diagonals 6 and 7 specifically exist across two areas, it can be inferred that they are located somewhere on the diagonal, making it easier to arrange each piece. become.

The marks that serve as the basis for roughly sorting each piece can be characters, symbols, figures, or a mixture of them.

In this way, in this invention, even if the scale of the jigsaw puzzle is large, the back side is divided by marks (marks), so it can be roughly sorted based on the classification, so in reality, each It is sufficient to consider the arrangement by dividing it into sections, and after completing the arrangement within each section, by connecting the sections together, it is possible to finally complete a large jigsaw puzzle. Therefore, even if the product of this invention is large-scale, it is now possible for enthusiasts of a relatively young age to try and complete the arrangement, so it is beneficial for both manufacturers and users. It is.
