DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a block-type building block 1 according to the present invention. The block-type building block 1 is composed of a block main body 2 having a square shape in a plan view, and a plurality of connecting portions 3 protruding from an outer periphery of the main body 2.

The block body 2 has a square through hole 4 penetrating in the thickness direction at the center. The through holes 4 are provided with connecting holes 5, 6, 7, 8 extending in four directions, up, down, left, and right (in the direction of each side of the block main body). The cross hole 9 has the same shape and the same size as the through hole and is formed in the center of the block main body 2 as a whole together with the through hole 4.

The connecting portions 3 are formed in the same shape and the same cubic shape. The block main body 2 is provided so as to project in a direction perpendicular to each of the side portions 10, 11, 12, and 13, and each of the upper side portion 10 and the lower side 11 has
And three on the left side 12 and the right side 13. Joint 3 of upper side 10 and lower side 11
a, 3b (hereinafter, referred to as a first coupling portion)
And the through hole 4 at the center of the lower side portion 11 in the left-right direction.
At intervals approximately equal to the width of

That is, when the block body 2 is divided into five equal parts in the left-right direction, the first and second positions from the left
Coupling portions 3a, 3b are provided, and the first, third, and fifth are three first concave portions 14, 14, 14, into which the coupling portions 3 of the other block-type blocks can be fitted. Also,
Joints 3c, 3d, 3 of the left side 12 and the right side 13
e (hereinafter, referred to as a second coupling portion) are provided at both ends and the center of the left side portion 12 and the right side portion 13 in the vertical direction, respectively. Between these second coupling portions 3c, 3d, 3e,
There are two second concave portions 15, 15 having an interval at which the joining portion 3 of the other block-type building blocks can be fitted.

That is, as shown in FIG. 2, when the block body 2 is divided into five equal parts in the vertical direction,
The second and third coupling portions 3c, 3d, and 3e are provided at the fifth and fifth positions, and the second and fourth coupling portions 3c, 3d, and 3e
5 is set. Therefore, the first connecting parts 3a, 3b are connected to the second connecting parts 3c, 3d, 3e of the other block type building blocks 1.
(The second recesses 15, 15), and when the block-type building blocks 1 are connected to each other as shown in FIG. 3A, the vertical positions of the block main bodies 2 match.

Therefore, as shown in FIG. 3B, a cube can be formed by connecting six block-type building blocks 1. The first connecting portions 3a, 3b can be fitted into the connecting holes 5, 6, 7, 8 of the cross hole 9. In this case, as shown in FIG. 4, the first coupling portions 3a, 3a, 3b is fitted. The distance between the opposed coupling holes, that is, the width of the through hole 4 at the center of the cross hole 9 is determined by the first coupling portions 3a and 3b.
(The width of the second recess 15), and
When the coupling portions 3a and 3b are fitted into the coupling holes, the positions of the first concave portions 14 and the through holes 4 coincide with each other.

Since the cross hole 9 has two pairs of opposed coupling holes, it can be fitted to the other pair of coupling holes.

[0012]

[Effects of the Invention] As described above, according to the present invention,
The connection with the other block-type building blocks is strengthened, and the connection portion of the two legs can be fitted into the cross hole of the block body from two directions.
