Description

Three-dimensional puzzle and its foldable piece structure

Technical field

The invention relates to a jigsaw puzzle, in particular to a three-dimensional puzzle for assembling a body product.

The invention also relates to a foldable panel that can be assembled into a three-dimensional product of different shapes. Background technique

Jigsaw is a very popular toy. At first, people used mostly flat puzzles. It is a relatively large flat pattern composed of several small flat patterns, that is, the pattern is printed on cardboard or printed in a flat format. On the plate of other materials, the plate body is cut into a plurality of small pieces, and when the puzzle is used, the small pieces whose edges can be matched with each other are assembled according to the characteristics of the pattern to form a complete pattern.

As people's demands for the fun and diversity of jigsaw puzzles have increased, there have been three-dimensional puzzles that can be assembled to form body objects. A three-dimensional puzzle, as disclosed in U.S. Patent No. US005860650A, which is formed by a plurality of foldable tiles and planar tiles into a three-dimensional puzzle. The foldable piece of this structure, such as its side piece, is folded in half by a V-shaped groove. The disadvantage of this type of construction is that the angle of folding is single and can only be determined by the angle of the V-groove. If there are multiple angles of folding, a variety of mold supports are required, and the processing difficulty and cost increase. Another point is that the structural strength of the tiles after folding is small, and the two folded bases are only connected by a small piece of tabs at the bottom of the V-shaped groove, which is easy to break during the assembly process.

Summary of the invention

The object of the present invention is to overcome the disadvantages of the prior art and provide a structural strength,

Confirmation And it is easy to process into a variety of folding angles of the three-dimensional puzzle and its foldable piece structure.

In order to achieve the above object, the technical solution of the present invention is as follows:

A three-dimensional puzzle comprising a planar panel and a foldable panel, a connecting portion being provided between adjacent folding bases on the foldable panel, the connecting portion being constituted by a peak-shaped folded sheet distributed along the folding line.

Wherein the connecting portion comprises 2 to 8 peak-shaped folded sheets distributed in parallel.

The foldable panel comprises at least two folded bases, the joint being disposed between adjacent two folded bases.

Collapsible tiles generally include two types of edge tiles and corner tiles. The edge panel is comprised of two fold bases and a joint for joining the two fold bases; the corner panel includes at least three fold bases and at least two joints for joining adjacent fold bases.

On the basis of the above three-dimensional puzzle, the present invention also designs a foldable panel structure, wherein the foldable pieces are provided with connecting portions between the adjacent folded bases, and the connecting portions are folded by peaks distributed along the folding line. Piece composition.

The connecting portion includes 2 to 8 peak-shaped folded sheets distributed in parallel.

The peak angle of the peak-shaped folded sheet and the angle of the valley between adjacent peak-shaped folded sheets are greater than zero degrees and less than 45 degrees. The optimum angle is 25 degrees, and the distance from the valley angle to the surface of the folded base is less than 0.3 mm.

The foldable panel includes at least two folded bases, the connecting portion being disposed between adjacent two folded bases.

The foldable panel comprises a side panel and a corner panel; the edge panel is composed of two folding bases and a connecting portion for connecting the two folding bases; the corner panel comprises at least three folding bases And at least two connections for connecting adjacent folded bases.

As can be seen from the above technical solution, the peak angle of the peak-shaped folded piece, the valley angle between the adjacent peak-shaped folded pieces, and the number of the peak-shaped folded pieces can be selected in accordance with the angle of bending of the foldable pieces. During the folding process, the angle of the peak angle is unchanged, the angle of the valley angle is reduced to zero, and the peak shape of the folded sheet and the angle are different, and different bending angles are realized. Since the shape of the peak-shaped folded sheets is the same, the processing difficulty is low, and the peak-shaped folded sheets serve as a support after folding, which improves the structural stability after folding of the folded pieces, and enables multiple folding. Another point is that the outer edge of the folded piece after folding is a circular arc surface, which is not easy to cause harm to people, especially for children.
