Components may be used to build a three-dimensional (3-D) model. The components can include supports and connectors. A subset of components can be selected based on the 3-D model. The subset of components can be used to build the 3-D model.

A construction set for erecting structures that can be assembled and disassembled. Functional capabilities of a construction set are expanded, which makes it possible to assemble a high-strength structure. Blocks with a square cross-section having faces of different widths and lengths, identical circular apertures, and an internal longitudinal passage are provided, for connection in a longitudinal and a transverse direction to form angles that are rigidly and movably connected. The blocks are made of square tubing of compatible standard sizes. Auxiliary parts are produced by cutting away an end face of a block, making it possible to use the blocks as pivotable levers and to use a unified fastening connective element as a pivot pin, where the position of one of the blocks changes along spherical coordinates relative to the conjugation point.

A modular playing block system is provided. The block system comprises at least one storage container. The at least one storage container is has a hole. The block system also comprises a plurality of connectors, wherein each of the plurality of connectors is inserted in a hole of the plurality of holes to form different arrangements, and each of the plurality of connectors act as a support for the arrangements.

A bracket for modular luminaire includes a polyhedral module and a connector connected to the polyhedral module. The polyhedral module is a polyhedron provided with a cavity therein, and each surface of the polyhedron is provided with a stepped through-hole connected to the cavity, thereby forming a first annular protrusion at a junction of the stepped through-hole and the cavity. The connector includes a connector body having a cylindrical shape. On an outer periphery of the connector body, a second annular protrusion, a third annular protrusion, a fourth annular protrusion, and a fifth annular protrusion protrude outwards in a radial direction and are spaced apart from each other, and formed successively from a left end portion to a right end portion of the connector body. A left end of the connector is inserted into the stepped through-hole of the polyhedral module.

A construction toy and game comprises a base, a core, and a first balance rod to operatively balance the core on the base. The construction toy and game further comprises a first weight component and a second balance rod to operatively connect the core to the first weight component.

A base member configured for use with a windowed magnetic tile, the base member including a tile portion having three or more outer edges configured with respective protrusions for fitting engagement with respective notches on corresponding three or more inner edges of the windowed magnetic tile; a first projection extending outwardly from a first surface of the tile portion formed by the three or more outer edges; and a first opening disposed on the first projection.

The invention relates to a coupling element comprising a body with an axial axis arrangeable in an opening of an object, which body is provided along its outer periphery with at least one outward extending locking cam, wherein the body is provided with at least one resiliently movable tongue extending therefrom, to which tongue the locking cam is connected, wherein the at least one tongue is movable inward by a force being exerted thereon.

A structure for providing accessibility to knowledge skills of load bearing includes several cubes. Each cube includes bores formed through each facet of the cube that are suitable for receiving pegs or link members, and each cube includes markings in order to assist in identification of the and/or an internal cube at a center of the cube.

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.
