[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a three-dimensional forming member for assembling and forming three-dimensional objects such as various polyhedrons, spheres, and cylinders.

"Conventional technology" Conventionally, the three-dimensional object to be formed is set in advance,
The necessary forming elements and the joints of each element are processed and formed on the three-dimensional object, and the desired three-dimensional object is obtained by combining these elements.

``Problems to be solved by the invention'' However, in the case of the above-mentioned conventional means, the three-dimensional forming elements and joints have different shapes and sizes, and there are many types of parts, making it difficult to assemble, and the cost is high. There was also the problem that only one type of limited three-dimensional object could be formed using these parts.

``Means for Solving the Problems'' However, the present invention includes a joint that connects a plurality of bone bodies and face pieces in a three-dimensional shape, and the joint has a plurality of connecting arms having a spherical portion at the tip on a flat outer periphery. It has engagement grooves and engagement holes on the outer periphery and the center that protrude and allow the joints to interlock with each other in a cross-shaped manner, and the two ends of the bone body and each apex of the face piece are press-fitted into the spherical part. Each arm groove is provided to allow the

"Function" Therefore, according to the present invention, three-dimensional objects of various shapes can be formed by the bones and face pieces, which are the smallest units, and the assembly and disassembly operations can be easily performed.
In addition, it has excellent propagation ability and can obtain a unique three-dimensional shape.
It can be applied to all relatively small three-dimensional objects, and when stored after disassembly, it can be stored compactly in a minimum space without taking up much space, making it convenient to handle when not in use. .

"Embodiment" An embodiment of the present invention will be described below in detail based on the drawings.

As shown in FIGS. 1 and 2, numeral 1 in the figures is a three-dimensional forming joint in which six connecting arms 2 are integrally formed at equal intervals on the outer periphery, and a pair of engagement grooves 3, 3 are formed facing each other, and an engagement hole 4 into which the joint 1 of the 3 part is fitted is formed approximately in the center of the joint 1, and as shown in FIG. ,1
The joints 1a are joined together in a cross shape to form an angle-adjustable combined joint 1a. Also, the joint 1
is made of an elastic material that allows the angles of its main body and each arm 2 to change to some extent and has a rigidity above a certain level.

In other words, the joint 1 is made of an elastic material such as synthetic resin having a rigidity above a certain level, and as shown in FIG. The other joint 1 is bent and inserted into the center engagement hole 4 of
The two joints 1, 1 are fitted in such a manner that the bottoms of the engagement grooves 3, 3 are in contact with each other, and the two joints 1, 1 are integrally connected thereto in a cross shape to form a combined joint 1a.

As shown in FIGS. 3 and 4, a rod-shaped bone body 5, which is a three-dimensional forming element, is provided, and the arm 2 and a spherical portion 2a formed at its tip are inserted through notches 6 at both ends of the bone body 5. Forming an arm groove 7 to be press-fitted,
A plurality of bone bodies 5 are connected through joints 1 in various configurations. Further, a joint groove 8 is formed in the center of the bone body 5 so that the two bone bodies 5 can intersect in a cross shape on the same plane, and slanted grooves are formed at a constant interval on both sides of the joint groove 8. 9,9
The left and right inclined grooves 9, 9 are arranged in a V-shape on both opposing sides, so that five or six bones 5 can intersect in a star shape on the same plane. Note that a plurality of notches 10 for preventing the arm 2 from being pulled out are formed in the arm groove 7 in a protruding manner. Further, the material for forming the bone body 5 contains a fluorescent dye.

As shown in FIGS. 5 and 6, a triangular face piece 11 which is a three-dimensional forming element is provided, and a fitting side edge 12 shaped to engage approximately half of the bone body 5 is formed on the outer periphery of the face piece 11. , an arm groove 13 into which the connecting arm 2 and the spherical part 2a are press-fitted is formed in each vertex 12a of the fitting side edge, and the plurality of face pieces 11 are connected through the joint 1 in various forms. There is.

Three-dimensional objects of various shapes are formed by connecting the single joint 1 or the combined joint 1a formed as described above to various combinations of the three-dimensional forming elements, the skeleton 5 and the face piece 11.

For example, when forming a regular tetrahedron 14 as shown in FIG.
By connecting them in a triangular shape via a, a regular tetrahedron 14 having a skeletal structure is formed. In addition, each vertex 1 connects four face pieces 11 via four single joints 1 or four sets of combined joints 1a.
By connecting 2a, a regular tetrahedron 14 that can be divided into planes is formed. Furthermore, it is also possible to combine the face piece 11 with the regular tetrahedron 14 having the skeletal structure.

In other words, as shown in FIG.
When forming the facepiece 14, the arm grooves 7 of the three ribs 5 are press-fitted into the spherical portions 2a of the three equally spaced arms 2 among the six radially protruding arms 2 of the joint 1. Then, this regular tetrahedron 1
A regular tetrahedron 14 is formed by forming one apex of a joint 1 and connecting the other end side of this bone body 5 to each arm 2 of a joint 1 forming the other apex.

In this way, cubes of various shapes are formed by using the single joint 1 as one joint, or by using the combined joint 1a, which is a combination of two single joints 1, as one joint, and by deforming these joints. Also, the above positive 4
Similar to the face 14, regular n-hedrons, n-hedrons, and n-prisms can be formed, and by connecting these same polyhedra or connecting separate polyhedra to each other, regular and irregular polyhedra can be formed. It can multiply indefinitely.

For example, in the case of a regular icosahedron, it is possible to connect the bones 5 with only a single joint 1, so there is no need to connect the two joints 1, 1, and the engagement grooves 3, 3 and the connection hole 4. You may also use a joint without.

Application examples of this embodiment include, for example, it is possible to easily form propagation toys, teaching materials, mobiles, interior decoration items, shelves, tent frames, etc., as well as the packaging of flowers, glass products, etc., and the frame of horticultural greenhouses. Very frequently used.

Also, on the shelves and tables mentioned above, the 8th
As shown in the figure, the frame body 5 can be omitted by providing a face piece 15 that is similar to the face piece 11 and connecting a plurality of triangular faces together. Further, FIG. 9 shows a modification of the face piece 15, in which a square face piece 16 is provided.

Although each of the face pieces 11, 15, and 16 is shown as a flat plate, it is also possible to form a cylinder or a sphere by forming these into curved or spherical surfaces.

"Effects of the invention" As is clear from the above embodiments, this embodiment includes a joint 1 that connects a plurality of bone bodies 5 and face pieces 11 in a three-dimensional shape, and a spherical part 2a on the flat outer periphery of the joint 1. A plurality of connecting arms 2 are formed protruding from the tip, and engagement grooves 3 and engagement holes 4 for intersecting the joints 1 are formed on the outer periphery and the center, and both ends of the bone body 5 and Face piece 1
1 are provided with arm grooves 7 and 13 that are press-fitted into the spherical part 29, respectively. In addition to being able to form three-dimensional objects, it is also easy to assemble and disassemble, and has excellent propagation ability to obtain unique three-dimensional shapes. can be applied to all products,
Moreover, when stored after disassembly, it can be stored compactly in a minimum space without being bulky, and it has practical effects such as being convenient to handle when not in use.
