First, the cube assembly block according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 3.
FIG. 1 is an example of an assembly block having a pair of uneven joint portions on the side surface, and FIGS. 1 (a) and 1 (b) show a perspective view from the upper surface direction and a perspective view from the lower surface direction, respectively. .. The upper surface 12 of the cube 1 has a convex portion A, and the lower surface 13 has a concave portion B that is aligned with the convex portion A of the upper surface 12. The

side surfaces

14, 15, 16 and 17 surrounding the upper surface 12 and the lower surface 13 have a convex portion C (with a symbol only for the representative portion) and a concave portion D (with a symbol only for the representative portion) adjacent to each surface. All the uneven portions on the side surface are formed perpendicular to the upper surface 12 and the lower surface 13, and one end coincides with the upper surface or the lower surface. The uneven portions D and C of the side surface 14 are aligned with the uneven portions C and D of the opposing side surface 16. The uneven portions D and C of the side surface 15 are aligned with the uneven portions C and D of the opposite side surface 17.

By having the concave portion D and the convex portion C on the side surfaces 14 to 17 at the same time, it is possible to prevent the combined portion from shifting in the vertical direction after the combined portion, and the connection between the assembly blocks is stable.

A structure in which the uneven wall of the side surfaces 14 to 17 is perpendicular to the upper surface 12 and the lower surface 13, the uneven wall is adjacent to each other, and the wall facing the adjacent wall is in contact with the upper surface 12 or the lower surface 13 is used when the assembly block is manufactured. In addition, an assembly block can be easily manufactured by using a formwork that is divided at the surface where the uneven wall is in contact.

The side walls of the concavo-convex portions D and C formed on the upper surface 12, the lower surface 13, and the side surfaces 14 to 17 have an inclination that spreads outward with respect to the base as shown in the cross-sectional shape of the concavo-convex combined portion in FIG. , It is prevented that the combined portion after the combination is vertically displaced from the base surface, and the combination is stable. The assembly block is made of a rigid and elastic material such as ABS resin, but the stability of the assembly can be maintained by distorting the assembly block material to the extent that it does not exceed the elastic limit of the assembly block material. If this amount of strain is too large, the durability when the merging is repeated is lowered.

This distortion can be mechanically considered with the "cantilever" model. When a load is applied to the tip of a horizontal cantilever with a fixed base end, the cantilever tilts and stress is concentrated on the fixed portion. When the stress of the fixed portion exceeds the elastic limit, plastic deformation occurs. Experience shows that the limit inclination angle at which plastic deformation does not occur is 5 degrees or less. Furthermore, from experience in handling elastic bodies, it was found from experience that the durability against repeated strains decreases when the strain angle is 3 degrees or more. Therefore, the (spreading) inclination angle 2 with respect to the base surface of the uneven portions D and C wall surfaces needs to be 5 degrees or less, and in order to further improve the durability of repetition, the inclination angle 2 is preferably 3 degrees or less. Further, in order to facilitate the alignment, it is desirable that the side wall tip portion 3 has an obtuse angle.

FIG. 3 shows an octagonal model 4 assembled with the assembly block in this embodiment. Unlike the conventional one-way integrated block and the block that requires connecting parts (Patent Document 2), only one type of block is used in three directions (horizontal direction, height direction and depth direction, more specifically, 3). In the space of the Cartesian coordinate system of the dimensional space, the connection is widened to three number straight lines X-axis, Y-axis, and Z-axis directions that are orthogonal to each other), and it is possible to easily create a complicated and three-dimensional shape. can.

The assembly block of the present embodiment has the block shown in FIG. 1 as a unit, but a block having a shape in which a plurality of blocks are combined in advance can be produced in order to easily assemble a complicated shape as shown in FIG.
