  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  This assembly block is composed of a flexible block plate 1 made of a strip-shaped plastic thin plate as shown in FIGS. 1 and 2, and a joint 21 which is a plastic rigid body as shown in FIG. The The joint 21 is the same as that used in the existing assembly block shown in FIG.

  The block plate 1 shown in FIG. 1 has a rectangular shape and a straight end type in which the short side is perpendicular to the long side, and the block plate 1 shown in FIG. 2 has inclined sides on both ends with respect to the longitudinal direction. It is of the bevel end format. These block plates 1 are provided with semicircular receptacles 2 facing each side in order to connect the joint 21.

  A protrusion 3 extending in a direction intersecting the insertion direction of the joint 21 is formed at a portion of each block plate 1 facing the insertion end of the receiving port 2. An abutting wall 4 swelled in a semi-annular shape is provided at the inner edge of the receiving port 2.

  On each side around the block plate 1 shown in FIGS. 1A, 1B and 1C, two existing square block plates 11 are provided via a basic joint 21 shown in FIG. Corresponding to the dimensions when three, four are connected in a row, the receptacles 2 are respectively arranged.

  On each side around the block plate 1 shown in FIG. 1 (d), dimensions are obtained when three existing square block plates 11 are connected in a row through a wide-spaced joint 21 shown in FIG. 3 (e). Corresponding to each, the receiving port 2 is arranged.

  An existing equilateral triangular block plate 11 is attached to each side around the block plate 1 shown in FIGS. 2A, 2B, and 2C via a basic joint 21 shown in FIG. Corresponding to the dimensions when connected in a row, three, six, the receiving ports 2 are respectively arranged.

  Each joint 21 shown in FIG. 3 has a structure in which a groove 23 is provided on the inner surface of a bifurcated plug 22 and a prismatic side extending portion 24 extends from the base of the plug 22 to both sides.

  The joint 21 shown in FIG. 3A is a basic type in which the plug 22 protrudes in two directions within the same plane, and the joint 21 shown in FIGS. 3B, 3C, and 3D is respectively The plug 22 protrudes in two directions, three directions, and four directions orthogonal to each other.

  Further, the joint 21 shown in FIG. 3 (e) has a base 22 with a wider gap between the base ends than the basic type, and connects the existing regular triangular block plates 11 with their directions reversed alternately. This corresponds to the connection in a wide gap portion that occurs when the block plate 1 shown in FIG. 1 (d) or FIGS. 2 (b) and 2 (c) is used.

  In this assembly block, since the block plate 1 itself can be curved as described later, it is necessary to use one in which the plug 22 protrudes in two directions at an angle of 120 ° as in the existing assembly block. There is no.
