MODEL CONSTRUCTOR Russian patent published in 2019 - IPC A63H33/10 

FIELD: machine building.

SUBSTANCE: invention relates to the model of assembling demountable structures. Model constructor comprising blocks of square cross-section, having rectangular faces of different width with round identical holes made on them, inner longitudinal passage, adapted for connection in longitudinal and transverse direction; constructor includes auxiliary parts adapted for connection to each other, one of which is made in the form of a hollow part in the form of a cube with four faces, on each of which there are holes, the centres of which lie in one plane, wherein three holes have shape and size coinciding with shape and size of holes arranged on blocks, fourth hole has larger size, and other auxiliary part is made in form of fragment of block of specified length, which includes end part of unit, in which on two opposite faces there are cuts, and edges of two other opposite faces are rounded; interconnected auxiliary parts provide connection of blocks, in which position of one of conjugated units, capable of changing during its rotation relative to conjugation point, located on conjugated edge of another block, is determined by spherical coordinates at any point of the surface of the hemisphere, which is bounded by the plane in which the conjugated face is located, wherein the radius of the hemisphere is equal to the length of the block, the position of which can change as the object rotates relative to the conjugation point of the blocks.

EFFECT: technical result ensured by useful model is expansion of functional capabilities of model designer, allowing to collect various structures of high strength.
