CHILDREN CONSTRUCTION KIT FOR CREATIVE ARBITRARY CONSTRUCTION Russian patent published in 2020 - IPC A63H33/04 A63H33/10 

FIELD: children's construction sets.

SUBSTANCE: construction set for construction objects comprises three-dimensional shaped elements, mainly differing in shape and size, articulated with each other by means of collapsible joints formed as a result of presence in said three-dimensional elements of process holes size, which is made sufficient for connection with preferably rod-shaped fasteners participating in formation of stable composite objects capable of containing an unlimited number of three-dimensional elements, appearance of which, as a rule, in a combination with said rod means imitates a visual image of the structure designed by the builder. Location of process holes in relation to facets of shaped elements is preferably set at the rate of one hole on one face, two holes on one face and four holes on one face, wherein the axis of one hole along one face is conditionally located in the center at the intersection of the diagonals, the axes of the two holes on one face are conventionally arranged along the diagonal in the middle of the sections from the vertices to the intersection of the diagonals, and axes of four holes on one face are conventionally located on diagonals at preferably equidistant distance from each other in the middle of sections from vertices of diagonals to point of their intersection. In each of the three-dimensional figured elements part, made in the form of a cubic, mainly one of the process holes on four faces and four process holes on two faces, provided that at least one of the above holes is through, and the other is made at an indirect angle with respect to the plane of its face, providing formation of an inclined and a movable connection of shaped elements having an extended orientation in three-dimensional space. Said collapsible joints formed as a result of docking of process holes with rod fasteners comply with the condition, which means that depth of blind hole and length of fastener are calculated from ratio I=L/2+(0.9–1.1 mm), where I is the depth of the blind hole, and L is the fastener length.

EFFECT: higher speed and ergonomics of construction, as well as high degree of reliability of simulation of obtained objects.
