DEVELOPMENTAL CONSTRUCTOR Russian patent published in 2025 - IPC A63H33/08 

FIELD: games.

SUBSTANCE: invention relates to developmental toys-constructors, consisting of a system of structural elements, and is aimed at development of logic, fine motor skills, mathematical abilities, speech, spatial imagination, social and communication skills and perseverance in children. Developing constructor contains the main cubic elements having square-section projections with chamfers on some faces and slots corresponding to them on the other faces, made with the possibility of fixation of the main elements to each other by arrangement of protrusions of one main element in slots of the other main element. According to the invention, the main element of the cubic shape consists of the upper and lower segments of the outer cube, six spring-loaded locks, six spring-loaded retainers, and one inner cube, wherein fixation of two elements between each other is carried out arrangement of protrusions of one main element in the grooves of the other element, in which one of the protrusions of one main element actuates the retainer of the second main element, which provides the retainer displacement, release and movement of the spring-loaded lock until it is fixed by the spring. All faces of the main element with protrusions and slots represent a working surface for coupling and fixation of the main elements to each other. Main element has on each of its six faces two projections with chamfers and two grooves formed from walls of each projection and a collar passing along the whole perimeter of the working surface; at that, projections and grooves are arranged on each face of the main element in a staggered order. In one of two slots of each working surface of the main element there is a retainer. In one of two protrusions of each working surface of the main element there is a lock, and in the second protrusion of each working surface of the main element there is a blind conical hole. Upper and lower segments of the external cube on the protrusions of the working surface have convexities in the form of a flat cylinder, one on each protrusion, wherein bulge on one of two protrusions of working surface is intended for pressing on retainer of mating main element, while bulge on second protrusion of working surface is a decorative element. Upper and lower segments of the outer cube have six protrusions on the outer side, two protrusions on the upper face of the upper segment and the lower face of the lower segment, and one on each of the side faces of the segments. Upper and lower segments of the outer cube on the inner side of the three of the six projections have recesses with through holes, and on the outer side of the other three projections there are blind conical holes, the axes of which are shifted towards the centre of the main element, wherein holes are made on sides of ledges. In slots of upper and lower segments of external cube there are through holes providing passage of external protruding cylindrical part of retainer. Upper and lower segments of external cube on inner side have places for arrangement of springs and stops, wherein retainers of locks on blind faces of upper and lower segments coincide with location of springs of locks of lateral faces of segments. Upper and lower segments of the external cube have holes to provide passage of cylindrical protrusions of locks. Top and bottom segments of outer cube have recesses on inner side to allow passage of circular protrusions of locks. Upper and lower segments of the external cube on one of the four side ribs have a longitudinal slot to accommodate the projection of the internal cube. Lock has a cylindrical projection, a locking member in the form of a cone, placed on the flat part of the lock through a trapezoidal prism with a chamfer, and a groove for a spring. Lock on its upper and lower faces has one circular ledge with rounding, and on side faces it has equal chamfers. On the side of the cylindrical ledge, the lock has a section of reduced width. On one side the retainer has an external protruding cylindrical part with a chamfer, and on the other side there is a groove for installation of a spring. Inner cube on all six faces has places for arrangement of locks, in which there is a slot for a retainer with two recesses, wherein one recess is made in the form of a hole for installation of a spring, and the second recess is made longitudinally. There is a ledge on one of the ribs of the inner cube. On top and bottom faces of inner cube there are three projections, and on its side faces there are two longitudinal projections in form of belt, at that all projections are intended for correct positioning of inner cube in top and bottom segments of the main element.

EFFECT: invention widens the range of developmental constructors, provides reliable connection of basic elements and promotes development of cognitive abilities in children.
