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 they are fitted together in an orderly manner, a unified pattern is formed. Because of the relationship between the pieces, the more unclear and confusing the pieces are, the more difficult it becomes to understand 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 provide a jigsaw puzzle that allows even younger people to fit together large jigsaw puzzles using positioning as a foothold.

The structure of this invention is that the back of the jigsaw puzzle is divided by color, and each piece is roughly sorted into several types of areas based on the division.

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

In both Figures 1 and 2, each piece 5, 5,
5 shows the back side of the entire jigsaw puzzle in which the correct arrangement of the parts has been completed.

In Figure 1, each piece of the jigsaw puzzle has eight sections of equal area and different colors, namely A1, A2, A3, A4, B1,
They are divided equally into B2, B3, and B4, and therefore pieces in the same area can be clearly distinguished from pieces in other areas, so all pieces are roughly divided into 8 categories based on that division. can do.

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

In the embodiment shown in FIG. 2, the pieces are color-coded into four sections C, D, E, and F, which are sorted by two diagonal lines 6 and 7, and all the pieces can be roughly sorted into four sections based on the color-coding. The positioning of the pieces within each area is conventionally determined based on a pattern (not shown) on the surface of each piece.

However, since the pieces on the two diagonals 6 and 7 specifically exist across two color-coded areas, it can be inferred that they are located somewhere on the diagonal, so the arrangement of each piece is further improved. becomes easier.

In this way, in this invention, the back side of the jigsaw puzzle is divided by color, so it can be roughly sorted based on that division. After arranging the sections, the sections can be connected to each other, and a large jigsaw puzzle can finally be completed. Therefore, even if the product of this invention is large-scale, it has become possible for enthusiasts of relatively young age to try and complete the arrangement, so it is of great benefit to both manufacturers and users. Beneficial.
