Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a joint piece that can be assembled into a three-dimensional shape such as a regular polyhedron.

(Background Art) There have been a variety of conventional joint pieces, ranging from relatively simple pieces like building blocks for children to pieces having a large number of pieces like a jigsaw puzzle.

Blocks like +iiT's could be assembled three-dimensionally, but they were no more than building blocks and lacked difficulty.

The latter type of jigsaw puzzle was difficult to assemble with many pieces, but it lacked a three-dimensional feel and there was no variation in the finished product.

On the other hand, when used as a prize for a product in addition to being used as an educational toy, each piece is not bulky and
We must also provide the joy of collecting items that gradually increase in number.

The purpose of the present invention is to solve the above-mentioned problems, and to create an image that is difficult to create in a standing position, gives a three-dimensional effect to the finished product, can be used in small numbers or in large numbers, and is suitable as a prize. The purpose is to capture and provide inner peace.

[Disclosure of the invention]

In order to achieve the above object, the joint piece according to the present invention includes a plate-shaped polygonal body, slopes formed at a constant angle on both sides of each side of the body, and a ridge line of the slope formed as a slope. A fitting recess formed on one side and a fitting protrusion formed on the other side and having a shape capable of fitting into the fitting recess are provided on each side of the main body alternately or continuously when viewed from one side. It is composed of a fitting part arranged as shown in FIG.

This joint piece is made of plastic and metal.

It can be manufactured using wood or the like, and the size is not particularly limited.

The main body may be plate-shaped, as long as it has a polygonal planar shape, such as a regular triangle, a regular quadrangle, or a regular pentagon.

Regular hexagons, etc. can be used. Moreover, when using this joint piece, if the lengths of the sides of the main body are the same, it is also possible to mix and assemble them.

If the shape of the main body is a regular triangle, a regular tetrahedron can be created, if the main body is a regular triangle, a regular hexahedron can be created, and if the main body is a regular pentagon, a regular dodecahedron can be created. Furthermore, by mixing regular triangles and regular quadrilaterals, a triangular prism can be created, and by combining regular pentagons and regular hexagons, a polyhedron such as a soccer pole can be created. Furthermore, some of the faces of the completed polyhedron may be missing, or it may be assembled so that it protrudes from the outer surface.

Moreover, each body does not have to be the same color, and by preparing bodies of various colors, three-dimensional bodies with different patterns can be created. Furthermore, if you print it out so that it looks like a picture in its entirety, you can use it like a three-dimensional jigsaw puzzle.

The shape of the fitting concave portion and the fitting convex portion serving as the fitting portions may be any shape as long as they are provided on each side of the main body and can fit with another joint piece at a certain angle. Basically, the concave portions and the convex portions are provided integrally on the front and back surfaces, and when viewed from one surface, they are provided alternately on each side. If the main body is an odd-numbered square, there will be continuous sides, which may also make assembly difficult.

The angle of the slope will vary depending on the number of sides of the main body, but it should be the angle formed by each piece when the polyhedron is assembled as a whole, approximately 55 degrees for a regular triangle and approximately 55 degrees for a regular quadrilateral. is 45 degrees, and in the case of a regular pentagon, it is 60 degrees. When pieces with different numbers of sides are mixed, the angle of the slope may be adjusted to a value corresponding to a piece with a smaller angle, or the angle of the slope may be set to two or more stages.

As another configuration, the main body may be provided with a fitting protrusion on one surface and a fitting recess on the other surface.

The fitting concave portion and the fitting convex portion are provided on the front and back surfaces of the main body, and each shape is not limited, but basically a cylindrical shape can be used. In this case, the number of fitting recesses and fitting protrusions is not limited, but they may be provided in correspondence with the number of sides of the main body. In this case, each joint piece can be stacked vertically by using all the fitting recesses and fitting projections, but it is also possible to stack the joint pieces vertically using a part of the fitting recess and fitting projection. can also be combined.

In yet another configuration, the main body may have a through hole in the center or recesses on both sides, so that another piece corresponding to the shape can be inserted.

In this case, the shape of the through hole may match the shape of the main body, or may be circular or star-shaped. If it is circular, it can also be used as a holder for displaying and storing coins. Each join corresponds to the G+n neck of the coin!・If you do the color division of the pieces, etc., furthermore,
The SJI combination of bonds will expand.

These joint pieces can be used as educational toys in sets of many pieces, or distributed and collected one by one as prizes.
