Double-sided jigsaw puzzle

Abstract

The double-sided jigsaw comprises a plurality of plastic splicing pieces which can be spliced with one another, concave-convex butt joint structures which are clamped with one another are arranged between the splicing pieces, chamfers are arranged on the edges of the upper side and the lower side of each plastic splicing piece, the height of the chamfers on the upper side and the lower side accounts for 3%-30% of the overall height of the plastic splicing pieces, and the chamfers on the upper side and the lower side of each plastic splicing piece are the same or different. And the chamfers on the upper side and the lower side of the plastic splicing piece are not arc chamfers at the same time. The chamfers are arranged on the upper side and the lower side of the plastic splicing piece, and the chamfers on the two sides are not arc chamfers at the same time, so that the splicing piece is convenient to pick up, and the upper side and the lower side of the splicing piece are convenient to distinguish. When the chamfers on the upper side and the lower side of the plastic splicing piece are not arc chamfers at the same time, the chamfers of the same type are different in height and can be easily distinguished, for example, beveled chamfers, inwards-concave chamfers and stepped chamfers can be easily distinguished through an observation method when the heights are different.

Description

Technical Field

[0001] This invention belongs to the field of intellectual development toys and children's toys, and specifically relates to a double-sided puzzle. Background Technology

[0002] Jigsaw puzzles are a very popular toy, consisting of multiple interlocking pieces that fit together to form a flat surface. Existing jigsaw puzzles are typically paper-based, printed on one side of cardboard and then machine-cut into pieces. Due to the nature of the material, the pieces are relatively thin, resulting in loose connections between them, requiring a flat frame for support. Furthermore, the puzzle easily falls apart after completion. To address this issue, new types of jigsaw puzzles have been developed using plastic as the raw material. For example, existing technology discloses a flat jigsaw puzzle made of plastic with chamfered edges on the top surfaces of the pieces, balancing ease of use with stability between pieces. Another existing technology discloses a flat jigsaw puzzle, also made of plastic, with rounded chamfers on both the top and bottom sides of the pieces, making them more aesthetically pleasing and smooth. Comparison document 1 features a rounded chamfer on the top of the plastic puzzle piece. However, when the bottom of the piece is placed on the ground, it is difficult to pick it up due to its high flatness. Comparison document 2 features rounded chamfers on both the top and bottom of the plastic puzzle piece. Although this design makes it easier to pick up the puzzle from the table or the ground, the rounded chamfers on both sides still make it difficult to distinguish the true back of the puzzle piece even with a height difference. This is very inconvenient when the puzzle is double-sided. Summary of the Invention

[0003] To address the problem of large gaps in the prior art, this utility model provides a double-sided jigsaw puzzle, comprising multiple interlocking plastic pieces. The pieces are connected by interlocking concave-convex joint structures. The key feature is that the top and bottom edges of the plastic pieces are chamfered, with the height of the chamfers accounting for 3%-30% of the overall height of the piece. The chamfers on the top and bottom edges may be the same or different, and not both sides are simultaneously rounded chamfers. Compared to the single-sided rounded chamfer of document 1 and the large double-sided rounded chamfer of document 2, this invention provides chamfers on both the top and bottom edges of the plastic pieces, and the chamfers on both sides are not simultaneously rounded chamfers, which facilitates both picking up the pieces and distinguishing the top and bottom edges of the pieces.

[0004] As a preferred embodiment of this invention, the plastic puzzle pieces have different patterns on their top and bottom sides. This allows for two ways to play with one puzzle piece, increasing its playability.

[0005] As a preferred embodiment of this utility model, when the chamfer types on the upper and lower sides of the plastic patch are different, their chamfer heights may be the same or different; when the chamfer types on the upper and lower sides of the plastic patch are the same, their chamfer heights may be different. When the chamfers on the upper and lower sides of the plastic patch are different and are rounded chamfers, it is easy to distinguish when the chamfer heights of the same type are different. For example, beveled chamfers, concave chamfers, and stepped chamfers can be easily distinguished by observation when their heights are different.

[0006] As a preferred embodiment of this utility model, the chamfer height of the lower side of the plastic patch is 15%-70% of the chamfer height of the upper side of the plastic patch.

[0007] As a preferred embodiment of this utility model, the chamfers on the upper and lower sides of the plastic patch are selected from: arc chamfers, bevel chamfers, concave chamfers, and stepped chamfers.

[0008] As a preferred embodiment of this invention, the upper and lower surfaces of the plastic patch employ two different surface treatment processes. For example: smooth surface, frosted surface, striped surface, and raised dot surface.

[0009] As a preferred embodiment of this utility model, it also includes a puzzle frame corresponding to the entire plastic puzzle piece.

[0010] As a preferred embodiment of this utility model, the plastic puzzle pieces are produced by injection molding, and the injection holes are located on the side of the puzzle piece or on one of the upper and lower sides of the puzzle.

[0011] As a preferred embodiment of this utility model, each piece is produced using a different injection mold.

[0012] Compared with the prior art, this utility model provides a double-sided jigsaw puzzle, which has the following beneficial effects:

[0013] This invention features chamfered edges on both the top and bottom sides of the plastic puzzle pieces, with the chamfers on both sides not being simultaneously rounded. This facilitates both picking up the puzzle pieces and distinguishing between the top and bottom sides. When the chamfers on the top and bottom sides of the plastic puzzle pieces are not simultaneously rounded, it is easy to distinguish between chamfers of the same type with different heights. For example, beveled chamfers, concave chamfers, and stepped chamfers can be easily differentiated by observation when their heights differ. This design makes it easier for users to pick up the plastic puzzle pieces and distinguish between the front and back sides, significantly improving the user experience, especially when designed as a double-sided puzzle.
