CONSTRUCTOR BLOCKS Russian patent published in 2019 - IPC A63H33/16 

FIELD: constructors.

SUBSTANCE: structural units can be used for creation of flat building structures from flat workpieces. Carton-shaped units have single (1) square cross-section, double (2) rectangular section and connecting element (3) are made of cardboard workpieces. Side walls of the blocks are made double with formation of inner volumes on the lower side to accommodate a connecting element. Thickness of the walls is formed by folding lines (12) and projections (13) bending inwards made on the ends of inner walls (14, 15, 16, 17) and lateral sides of inner walls (14, 16). In double unit inner walls (15, 17) consist of two parts (23, 24), between which valve (25) is made, and unit itself contains transverse partition (26), dividing its inner volume into two equal parts. Partition is made in the form of box open on ends of rectangular shape. Valves (32) are made on partition walls (28, 29) opposite to each other. When assembling the unit in their slots, valves (33) made at the ends of reinforcement walls (10) are fixed, and in the slot between them and side wall (31) of the partition wall, valve (25) is fixed. Connector element is box-shaped in square cross-section. At the ends of side walls (36, 37, 38, 39) there are connection projections (42) with slots (43) forming a bridge. Bridge is fixed in recesses (44) of slots (45) of upper walls (5) of blocks.

EFFECT: increased rigidity of blocks, increased service life and improved convenience of assembly.
