Abstract
Abstract The invention relates to a toy building block set comprising several plane blocks of various kinds. The building block set includes a cuboid panel block (1) having height h, width b and thickness d, an elongated beam block (2) with a square cross-section and length h and thickness d, and a trapezoid block (3) with thickness d, width of the tip nearly d, width of the base nearly b and length of a sloping side nearly h, the proportion of d:b:h being 1:3:4. The blocks, which are preferably made of synthetic material or wood, may be connected with each other by a peg and hole connection (4,5). The blocks may be used to construct very true-to-life and esthetically appealing structures.
