Abstract

A folding jigsaw puzzle sheet includes two hard plastic sheet elements (1, 2) connected by a flexible plastic slice (3) with a certain width. The flexible plastic slice (3) is positioned between the two sheet elements (1, 2). The width of the flexible plastic slice (3) is less than the side length of each sheet element (1, 2), so the shape of the folding jigsaw puzzle sheet is 'H'. The folding jigsaw puzzle sheet has a good folded angle.

Description

Bendable piece

一种可弯折的拼片Bendable piece

技术领域 Technical field

The present invention relates to the field of toy puzzles, and more particularly to a bendable tile.

背景技术 Background technique

The three-dimensional puzzle piece in the prior art has a bendable piece for use as a corner of a three-dimensional puzzle, but these currently available bent pieces are formed by forming a groove-like structure on the inner side. However, the current groove structure is a triangular groove type, and the disadvantage of these structures is that the precision of the processing is high, so that the bent piece is exactly the desired angle. especially The 180-degree folded structure makes the pieces easy to deform and rise, resulting in serious deformation of the corner of the three-dimensional puzzle, not the required angle, and it is impossible to splicing the beautiful three-dimensional effect.

发明内容 Summary of the invention

The technical problem to be solved by the present invention is to design a new bent piece structure which can overcome the defects of the prior art bending piece and provide a piece which has a good bending angle and is convenient for bending.

This patent achieves the above object by the following technical solutions.

This patent designs a bendable piece comprising two pieces of hard plastic unit pieces joined together, the improvement being that the unit pieces are joined to the middle by a soft plastic sheet having a certain width, the sheet The width is smaller than the length of the side of the piece, so that the entire bendable piece is ' H 'Shaped structure. The above structure connects two unit pieces by a sheet having a certain width, and the sheet is disposed between the two unit pieces to function as a connecting belt, so that the manufacturing precision does not need to be extremely precise. Due to the presence of the flakes, the jigsaw puzzles are not deformed due to internal stress, especially in the adaptation. Folded structure with a 180 degree corner.

The above structure can also be improved as follows:

One side of the two unit piece connecting sheets forms an inclined surface up and down.

The sheet is attached to the middle of the thickness direction of the unit tile.

After the bendable pieces are folded in half, the width of the sheets between the unit tiles is equal to the distance between the sheets and the joint points of the unit tiles.

The thickness of the sheet is from 0.05 to 0.2 the thickness of the patch.

The sheet extends into the interior of the unit tile.

The sheet extends to a portion inside the unit tile having a through hole through which the unit tile passes.

The unit tile has four sides, except for one side of the connection, the other three sides are straight sides or grooves or bumps having an Ω shape.

The above structure can well overcome the defects of high precision required by the existing jigsaw craft, and make it possible to produce large-scale and beautiful three-dimensional puzzles, and further reduce the cost, and can be applied in various three-dimensional puzzles, and has wide market application. Sex.

具体实施方式 detailed description

The patent is further described below in conjunction with the drawings.

A bendable piece as shown in Figure 1, consisting of two pieces of hard

plastic unit pieces

1 and 2 joined together The unit piece is connected to the middle by a soft plastic sheet 3 having a width, and the width of the sheet 3 is only about one-half of the length of the side of the piece, and the thickness is only 0.2. The thickness of the piece is such that the entire bendable piece has an 'H' shape.

Unit tiles

1 and 2 have four sides, except one side of the connection, the other side is a straight edge, and the other two sides have Ω Grooves or bumps for connecting to other tiles.

As can be seen in detail in conjunction with Fig. 3, one side of the two

unit tiles

1 and 2 connecting the sheets 3 forms a trapezoidal groove 32, and the sheet 3 Connected to the middle of the

unit tiles

1 and 2 in the thickness direction.

It can be seen from Fig. 2 and Fig. 4 that after the bendable pieces are folded in half, the width of the sheet 3 between the

unit pieces

1 and 2 is equal to the sheet 3 The distance from the junction point of

unit tiles

1 and 2. Substantially the sheet 3 extends into the interior of the

unit tiles

1 and 2. In conjunction with Figures 3, 4, 5, and 6, the sheet 3 The extension extending to the inner part of the

unit tiles

1 and 2 has a through hole 31, and one side of the

unit piece

1 or 2 is provided with a groove 12 for mounting an extension of the sheet 3, and a groove 12 is provided with a connecting post 11 Pass through the through hole 31 of the sheet 3. The extension of the

unit block

1 or 2 and the extension of the sheet 3 are detachable.

The above structure can be applied to links between large-scale puzzles, as shown in Figure 7. A screen puzzle composed of a plurality of unit puzzles is shown, and the two screen surfaces are connected by four structures of the present invention, and the detailed structure can be further referred to FIG. . This connection structure allows the two screen faces to be folded relatively, and the folded structure is shown in Fig. 9.

The structure of the present patent is not limited to the above embodiment, and specifically, different connection grooves and bumps, and sheets 3 may be designed according to the type of the tiles. The width.
