The building toy includes at least one basic element and at least one connecting pin. The basic element has a body where in the wall there is at least one connecting opening led perpendicularly onto the wall. The connecting opening runs through the body of the basic element as a transitory cavity and the connecting opening is designed for an insertion of the connecting pin. All connecting openings in the body are mutually spatially skew. The pairs of connecting openings from each wall run through the body to lie in mutually perpendicular and rotated planes and the distance of the connecting openings if each pair is identical and it is at least the length of a diameter of the connecting openings. The pairs in the central zone of the body avoid each other without the cavities of the connecting openings colliding mutually.

Disclosed is an asymmetric toy module, which comprises a sheet-shaped square module body. The front surface of the module body is provided with a first combining element. At least one side surface of the module body is provided with a second combining element combined with the first combining element. The second combining elements on at least two opposite side surfaces are arranged asymmetrically. A combined toy set comprises a plurality of the asymmetric toy modules and a plurality of connecting modules, wherein the second combining element of one of the asymmetric toy modules is combined with the first combining element of the other asymmetric toy module, and the two asymmetric toy modules can also be connected together through the connecting modules. The asymmetric toy module achieves presentation levels and can form various exquisite assembled structures through a simple and rapid combination of the modules, thereby having high flexibility.

A door hinge assembly includes: a door frame defining a frame opening and a jamb at one side of the frame opening, the jamb including two frame corners protruding into the frame opening and a jamb brace connecting the two frame corners across the frame opening, the jamb brace defining two spaced-apart hinge holes therethrough; a door movable to selectively provide access through the frame opening, and an elastic cord connecting the door to the door frame, the cord extending sequentially through a first of the two hinge passages, through a first of two passage openings at the jamb edge, through a first of the two hinge holes, across the jamb brace, through a second of the two hinge holes, through a second of the two passage openings at the jamb edge, and through the second of the two hinge passages.

The invention relates to producing kits for games and souvenirs. The invention consists in a node for connecting moving elements thereof in order to perform a connecting action using two groups of components. A first group of components and a second group of components are connected by means of inserting protrusions, which are positioned along opposing edges of at least two individual components of the second group, in at least two rectangular connecting apertures of one of the individual components of the first group, and which are disposed symmetrically relative to a central aperture on each of the individual components of the first group. The second group of components contains at least two individual components which are made in the form of symmetrical pairs. The result consists in the fastest and most-reliable assembly of the node.

Interlocking panels are assembled to form modules, and the modules are assembled to form a modular display case, for displaying, transporting and storing objects such as models, display items or valuable collectibles. The interlocking panels include interlocking side edge ball key tab including a resilient, compressible ball key, and ports for removably receiving the ball key tab and ball key.

The invention is a construction toy consisting of standard connector elements, e.g., rings, and strut elements, e.g., that may be joined in various angular configurations and with various types of articulation such as fixed, sliding, swinging, spinning, etc. Rings may be provided that have pairs of perimeter orifices that are offset by different amounts wherein the different offsets provide different functionality to ring and strut assembles. Other elements may be included such as pipes, slips, caps, base components and collar components. The elements may be combined to create various forms including a figure with human traits comprised of interconnecting strips and rings of various dimensions, a decoration, a vehicle, a bird, or many other forms in accordance with a user's imagination.

A construction set for erecting structures that can be assembled and disassembled. The technical result consists in expanding the functional capabilities of a construction set, which makes it possible to assemble a high-strength structure.

A modular construction kit includes modular construction blocks, each includes at least one interface face. The interface face includes a recess, a plurality of connection apertures disposed proximate to the edge of the recess, and a circular interface receptacle disposed in the center of the recess. The kit also includes modular construction connectors, each includes two opposite sides, wherein each side including a body, a plurality of connection studs extending outwardly from the body, and a protrusion extending outwardly from the body. Some modular construction blocks include predetermined functions. A modular system block includes at least a processor, storage, and wireless communication.
