Description

  The present invention relates to an assembly material that can be used as a toy material / furniture material, etc., which forms a framework structure by combining a plurality, an assembly material set, and a framework structure configured by the assembly material.

  DESCRIPTION OF RELATED ART Conventionally, the thing like patent document 1 or patent document 2 is known as an assembly material and assembly toy which can assemble the frame structure of various shapes.

  The assembly toy of Patent Document 1 is to assemble a toy having a three-dimensional structure by providing a projection and a connection hole for connection on the surface of a prismatic member and connecting them to other similar prismatic members.

  Moreover, the assembly material of patent document 2 uses the male member which has the protrusion for connection in the both ends of a plate-shaped member, and the female member which has the cutting for connection in both ends, and these are connected mutually. Thus, a three-dimensional structure is assembled.

  In addition, an assembly puzzle for assembling a cubic frame structure 6 as shown in FIG. 7A is known.

  The framework structure 6 shown in FIG. 7A is composed of 12 assembly materials 1, 2, 3, 4, 5,... Having substantially the same outer dimensions shown in FIG. ing.

  Moreover, the assembly materials 1, 2, 3, 4, and 5 are formed by cutting out two coupling shaft portions 8 slightly inward in the axial direction from both ends of a prismatic member having a substantially square cross section. .

  Further, the assembly materials 1, 2, 3, 4, and 5 are classified into five types depending on the difference in the shape of the coupling shaft portion 8.

  Then, two pieces of the assembly material 3 and the assembly material 4 corresponding to the pillar portions of the frame structure 6 are assembled, and the two assembly materials 1 and 1 are connected to each other. After constructing the base portion, the two assembly materials 5 and 5 are fitted into the upper part, and finally the two assembly materials 2 and 2 are fitted together, whereby the cubic frame structure 6 is completed.

  On the other hand, in order to assemble a cubic framework structure with the corners formed at right angles, it is desirable to provide the coupling shafts 8 at both ends of the assembly materials 1, 2, 3, 4, and 5. Since it is difficult to maintain the state, the coupling shaft portion 8 is disposed slightly inside from both ends of the assembly materials 1, 2, 3, 4, and 5.

As a result, both ends of the assembly materials 1, 2, 3, 4 and 5 have end portions 7 and 7 as the remaining portions. The end portions 7 and 7 are the main body of the cubic frame structure 6. It does not constitute.

  However, in the conventional assembly material as described in Patent Document 1, various types of frame structures are required unless a plurality of types of assembly materials having different sizes, shapes, connection protrusions and connection hole arrangements are used. I couldn't assemble my body.

  Further, since the connection is made by fitting from one direction, there is a problem in strength that the connection is easily released when a force is applied to the connection part from a direction other than the fitting direction.

  And since the projection for connection and the connection hole which are not used for connection are exposed, there was a problem that the aesthetics of the completed structure was impaired.

  Furthermore, the conventional assembly material as described in Patent Document 2 requires at least two types of assembly materials, a male member and a female member. In order to assemble various shapes of frame structures, Two types of assembly materials with different sizes were required.

  Further, since the connection is due to pinching, there is a problem in strength that when the force is applied to the connecting portion from a direction other than the pinching direction, the connection is displaced or the connection is easily released.

  Furthermore, this connection method can be used in the case of plate-shaped assembly materials, but it cannot be used as it is, for example, in an assembly material having a substantially square axial cross section.

  Further, in the conventional assembly materials 1, 2, 3, 4, and 5 as shown in FIG. 7B, a framework structure other than the cubic framework structure 6 cannot be assembled. There was no sex.

  Then, it is necessary to assemble five kinds of the assembly materials 1, 2, 3, 4, and 5 in the above order, and although there is a value as a puzzle, there is no freedom of assembly as an assembly material.

  Furthermore, as described above, the end portion 7 does not constitute a main body portion of the cubic framework structure 6 but has to be stopped on the structure of the connection, and is only a portion formed as a remaining portion. .

  Therefore, the present invention provides an assembly material capable of assembling a framework structure of various shapes by combining a plurality of basic assembly materials, with the portion corresponding to the end portion constituting the main body portion of the framework structure.

Can be used as an assembly material for any of the parts, and the assembly order is not limited.

  Furthermore, even if the assembly progresses, the entire assembly material can be rotated around the coupling shaft portion, so that two coupling portions can be assembled at the same time, and the degree of freedom in assembly is high.

  In addition, since a framework structure of various shapes can be assembled using a plurality of single assembly materials, the manufacturing cost can be reduced compared to the case where many types of assembly materials must be manufactured. it can.

  Further, according to the third aspect of the present invention, by using the end member that is half the length of the assembly material together with the assembly material, as compared with the case of assembling the structure using only the assembly material. Many shapes of frame structures can be assembled.

  According to a fourth aspect of the present invention, the end face of the main body end is brought into contact with each other by the axial total length of the central part of the main body of the assembly material being substantially twice the total length of the main body end. The two end portions of the main body that are continuous can form the main body portion of the framework structure in the same manner as the central portion of the main body.

  Therefore, frame structures of various shapes other than the cubic frame structure can be assembled using a structure in which the end surfaces of the main body end portions are in contact with each other and the main body end portions are continuous.
