The joint 21 shown in FIG. 7(a) is a square planar shape (see Patent Document 2), the planar shape shown in FIG. 7(b) is an equilateral triangle (see Patent Document 3), and the joint 21 is shown in FIG. 7(c). A shape (see Patent Document 4) is being considered.

A socket 12 with depressions on the front and back sides is formed on each side around the block plate 11, and the socket 12 is provided with an arcuate recess 13a and a circular recess 13b with a depression on the back side.

The joint 21 has a plug 22 with opposing tongues protruding in at least two directions, and the inner surface of the plug 22 is provided with an arcuate convex portion 23a and a circular convex portion 23b with raised end sides. Moreover, a prismatic side extension 24 extends from the base of the plug 22 toward both sides, and a deep square hole 25 that is open at the end surface is formed in the side extension 24 .

When connecting such block plates 11, when the plug 22 of the joint 21 is fitted into the socket 12 of the block plate 11, the outer edge of the plug 22 comes into contact with the step on the back side of the socket 12, and the arc edge recess 13a At the same time, the circular concave portion 13b and the circular convex portion 23b engage with each other, and the side extension portion 24 comes into contact with the outer circumferential surface of the block plate 11, thereby stabilizing the connected state.

There are several types of joints 21 depending on the connection mode, and the basic type is one in which the plugs 22 protrude in two directions on the same plane as shown in the figure, as well as two types in which the plugs 22 are orthogonal to each other. Some types of plugs are available, such as those that protrude in one direction, those that protrude in three orthogonal directions, those that protrude in two directions at an angle of 120 degrees, and those that have a large distance between the proximal ends of the plug 22.

In addition, as shown in FIG. 8, special parts of the assembly block include a joint 21 from which a shaft 26 extends, and a wheel member 31 that is inserted into and attached to the shaft 26. By combining these, it is also possible to assemble an automobile in which the shafts 26 protrude from the four corners of the vehicle body having an inclined surface in front of the cube-shaped connecting body, and the wheel members 31 are attached to each shaft 26.
