Abstract: An assembling block includes block plates having square and equilateral triangular plan shapes, respectively, and a joint for connecting the block plates together. Each of the block plates includes seat portions provided along the respective sides of the block plate, and retaining pieces extending from the center of the block plate to the outer edge thereof and spaced from the seat portions in the thickness direction. The joint comprises a plate member made of a flexible and bendable material, whereby when the joint is inserted between two of the seat portions and one of the retaining pieces of each block plate, the joint engages the seat portions with engaging protrusions formed on the seat portions fitted in engaging holes formed in the joint, thereby coupling the block plates together.

Abstract: An assembling block is provided which includes block plates 1 having square and equilateral triangular plan shapes, respectively, and a joint 2 for connecting the block plates 1 together, wherein each of the block plates 1 includes seat portions 3 provided along the respective sides of the block plate, and retaining pieces 4 extending from the center of the block plate to the outer edge thereof and spaced from the seat portions 3 in the thickness direction, and wherein the joint comprises a plate member made of a flexible and bendable material, whereby when the joint 2 is inserted between two of the seat portions 3 and one of the retaining pieces 4 of each block plate 1, the joint 2 engages the seat portions 3 with engaging protrusions 5 formed on the seat portions 3 fitted in engaging holes 6 formed in the joint 2, thereby coupling the block plates 1 together. With this arrangement, it is possible to easily construct a large variety of objects using minimum kinds of joints.

Abstract: A block which can be easily assembled into a large variety of shapes and sizes using a smaller number of kinds of joints at a low cost. The assembled block includes equilateral triangular block plates, square block plates, and joints through which the block plates are coupled together. Each of the joints is formed of a single, flexible and bendable plate having wing portions on both sides thereof. The block plates are made of a flexible material and have edges and receptacles each provided along one of the edges for accepting one of the wing portions of the joints. The receptacles are each formed with a guide pocket. Any two the block plates can be coupled together through any of the joints by inserting the respective wing portions of the joint into one of the receptacles of one of the two block plates through the corresponding guide pocket and into one of the receptacles of the other of the two block plates through the corresponding guide pocket.
