In addition, a coupling groove for rotatably engaging the coupling protrusion of the other frame is formed on the side of the one protrusion, characterized in that the coupling protrusion is rotatably coupled to the coupling groove of the other frame on the other protrusion side. do.

First, the assembled toy of the present invention enables the assembly of the desired polyhedron by connecting the side portions 31 of the respective frames 30 to each other, in particular, the fitting block 40 on each frame 30 of the assembled polyhedron. By assembling), it is possible to clarify the shape of the polyhedron to improve the understanding of the spatial figure.

Second, by forming the access grooves 36 in each frame, when assembling the frames 30 with various shapes of polyhedrons, the assembling angle is reduced to enable assembling into more polyhedrons.

Third, by forming the clearance groove 44 in the corner portion of the fitting block 40, by the clearance groove 44 to avoid interference with the corner portion of the frame 30 to facilitate the assembly and separation.

Fourth, by forming a gripping hole 45 in the fitting block 40, it can be stored by threading through a gripping hole 45, etc. during storage to prevent loss and to facilitate storage.

The assembly toy of the embodiment of the present invention by interconnecting the various types of frames to form a polyhedron of various shapes, so that it is possible to learn the spatial figure and further improve the understanding by clarifying the shape of the assembled spatial figure.

The assembly toy of the embodiment of the present invention is provided with a plurality of unit frames on the unit polygon to be connected to each other rotatably to assemble a polyhedron of various shapes.

3A and 4, the unit frame 30 employed in the assembly toy of the embodiment has a structure in which a space 35 is formed in the center by the side portions 31 forming a polygon.

In the exemplary embodiment, the frame 30 is described by taking a triangular polygon as an example, but may be implemented as a polygon having various shapes such as a rectangle and a pentagon, as shown in FIGS. 9 and 10.

The frame 30 has three side portions 31 positioned on three sides of a triangular shape, and a hinge structure is formed at the outer edge of each side portion 31 so that other frames 30 can be rotatably coupled thereto. It is.

As the hinge structure, at least one pair of protrusions 32 and 33 are formed at the outer edge of each side portion 31, and a groove 34 is formed between the protrusions 32 and 33.

As shown in FIG. 6, protrusions 32 and 33 of one frame of the frames 30 that are coupled to each other are door-locked to the groove 34 of the other frame, and each frame 30 is Removably and rotatably coupled to each other.

That is, one side of the protrusion 32 is formed with a coupling groove 32a to which the coupling protrusion of the other frame is rotatably formed, and the other side of the protrusion 33 is rotatably coupled to the coupling groove of the other frame. It has a structure in which a coupling protrusion 33a to be coupled is formed.

On the other hand, as a characteristic configuration of the present invention, the fitting block 40 is coupled to the space 35, the shape of the tetrahedron when the plurality of frames 30 are coupled to each other to form a tetrahedron as shown in FIG. Make sure you can observe clearly.

The fitting block 40 is formed in a shape corresponding to the space 35 of the frame 30 and is coupled to and detachably coupled to the inner edges of the respective side portions 31 forming the space 35. The fitting groove 43 is formed at the edge.
