Abrégé

In order to easily and accurately join substrates, and reliably connect block plates via a joint, a construction block is formed by combining block plates (1) having a square planar shape and an equilateral-triangle-shaped planar shape, and a joint (2) which connects the block plates (1). Therein, among two substrates (3, 4) which lie on top of one-another in each block plate (1), cut-out erectable pieces (5) which extend from the corner side to the central side are formed on one of the substrates (3) by means of incisions corresponding with each side, and slits (8) are provided in the other substrate (4), so as to correspond with the cut-out erectable pieces (5) and extending from the corner side to the central side; when the cut-out erectable pieces (5) are erected and inserted into the slits (8), an engagement section (7) in the cut-out erectable pieces (5) engages with the end edge of the slits (8), and the substrates (3, 4) are fixed; when an insertion piece (10) in the joint (2) is inserted into a receiving opening (13) in each of the block plates (1), narrow sections (11) in the insertion piece (10) engage with the cut-out erectable pieces (5), and thus the connection state of the block plates (1) is retained.

Abrégé

Construction blocks which can be assembled into various three-dimensional objects by changing the angle of connection between block plates by a joint.  The construction blocks comprise a combination of block plates (1) and a joint (2).  The block plates (1) have, in a plan view, a regular triangle shape and a square shape, and the joint (2) has plugs (10) projecting in at least two directions.  The plugs (10) of the joint (2) are engaged with the block plates (1) to connect the block plates (1) to each other.  The block plates (1) each have bar-like sections (4) extending along sides of the outer periphery of the block plate and connected between corner sections (3), and also each have a space section (5) facing the inner side of the bar-like sections (4).  When the plugs (10) of the joint (2) are fitted to bar-like sections (4) of the block plates (1), the space sections (5) prevent interference between the plugs (10) and the block plates (1).  A joint section (11) for interconnecting base ends of the plugs (10) also does not interfere with the outer periphery of the block plates (1), and as a result, the block plates (1) and the joint (2) can rotate about the bar-like sections (4) relative to each other.

Abrégé

A knockdown block capable of being assembled into various forms by using reduced kinds of joints, produced easily, and provided at low cost. The knockdown block is formed by a combination of block plates (1) having square and regular triangular shapes in a plan view and of joints(2) for connecting the block plates (1) to each other. Pedestals (3) and holding sections (4) are formed on each block plate (1). Each pedestal faces sides of the outer periphery of each block plate, and the holding sections (4) extend from the center to the outer peripheral side of the block plate with a spacing from the pedestal parts (3) in the thickness direction. The joints (2) are formed from a flexible bendable plate material. When the joints (2) are inserted between the pedestal parts (3) and the holding sections (4) of the block plates (1), locking projections (5) formed on the pedestals (3) are fitted into the locking holes (6) of the joints (2), the pedestals (3) are engaged with the joints (2), and the block plates (1) are connected to each other.
