A miniature track assembly having a plurality of central track supports, first track support spacers, and first and second flexible track runners is described. Each track support has a body portion and an extended portion attached to the body portion, the extended portion having a first connection node and a second connection node for detachable connection with the flexible track runners. The first track support spacer is configured to attach to at least one of either a central track support from the plurality of central track supports, or a second track support spacer. The first and second flexible track runners are configured to attach to the connection nodes of the extended portion of each of the plurality of central track supports. The components provide unique design and construction advantages due to the flexible track runner.

The application relates to a field of object connection and in particular, relates to a basic connecting block and a connecting block group. The basic connecting block includes a connecting block body, wherein at least one protrusion corner is provided on one side of the connecting block body and same number of inward recesses as the protrusion corner are provided on an opposite side of the connecting block body, and wherein a surface contour of the protrusion corner is consistent with that of the inward recess, the protrusion corners are connected with each other and the inward recesses are communicated with each other.

Connection systems for toy construction pieces, toy construction pieces, and toy construction kits. A connection system includes a male connection element and a female connection element. The male connection element includes a peg unit with a connector peg. The female connection element includes at least a portion of a connector core that defines a receiver cavity configured to receive at least a portion of the connector peg and at least a portion of a core shell. A toy construction kit for assembling a constructed assembly includes a plurality of toy construction pieces that collectively embody the connection system. A first construction piece includes the male connection element and a second construction piece includes the female connection element. The connection system is configured to selectively and repeatedly couple the first construction piece and the second construction piece to one another.

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.

The invention relates to a connecting system 1, comprising at least one hole carrier 2 with a row of side openings 4 made therein in a longitudinal direction, the openings being aligned in a first orientation and in a second orientation orthogonal thereto and being made transverse to the longitudinal direction, wherein the side openings 4 of the first and the second orientation are shifted by one half the distance between two side openings 4. According to the invention, the distance between two side openings 4 is smaller than the clear width of the side openings 4, the side opening 4 of the second orientation being made within this distance and the side openings 4 of the first and the second orientation partially penetrating one another. The invention further relates to a method for building an assembly from a connecting system 1 and to a use of a connecting system 1 having the associated securing and connection elements and the installation sequence.

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 building model connector is disclosed comprising a central body, an arm extending outwardly from the central body, the arm including a first arm portion, and a second arm portion, and first and second gripping teeth formed at the distal end of the first arm portion and the second arm portion, respectively, on the inner surface thereof. The first and second gripping teeth are configured to removably connect to a form such as a building panel. Corresponding systems and methods also are disclosed.

A toy, game, and/or puzzle building system may comprise variously shaped connectors that are operatively attachable to other connectors or rods. The connectors may include a receiving portion adapted to receive a rod and may connect two, three, four, five, etc. rods in various angles and orientations. The connectors may include a receiving portion adapted to receive another connector. Multiple rods may be connected in 2-D and 3-D configurations and orientations. Both the rods and connectors may be provided in a variety of lengths, shapes, colors, and sizes. Additionally, the connectors may be used with any existing items, such as a plastic or wooden toothpick, straw, stirrer, and the like, that may fit within the receiving portions of the connectors. The toy picks building system may be built into a particular shape, item, vehicle, animal, person, building, scene, or landscape.

A kit of structural parts connected by magnets is provided for the assembly of various architectural and structural models that simulate the behavior of cable structures, to understand different structural concepts. The kit includes an instruction manual, plates and other structural parts that facilitate the learning of the concepts through tactile and visual methods. Experimenting with various models allows a user to learn about the behavior of the structures. The structural parts include i) metal cables formed by multiple spherical and hollow elements connected to each other by rods with limiters; ii) cable clip elements with upper openings to receive the spherical elements; (iii) cable connecting parts having two linearly movable parts that enable extension or retraction of the cable connecting parts; (iv) bar stiffeners for high deformation bars to form rigid elements; (v) a cable cutter; and (vi) multiple cable clip parts for receiving multiple cables.
