A connector joint device for connecting rods or arms at a joint or intersection. The connector joint includes more than one hexagon shape faces, more than one octagon shape faces, more than one 4-sided polygon shape faces. A first face among the more than one octagon shape faces has a hole extending in a direction at an angle with respect to a perpendicular line to the first face.

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 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.

Embodiments generally relate to an interlocking brick design suitable for manufacturing with a 3D printer or other type of additive manufacturing. In one embodiment, a top cone having a slightly increasing diameter is formed on a top surface of an interlocking brick or other part. Another embodiment uses a bottom cylinder with notches formed on a bottom surface. The notches define flexible tabs which can have a thinner wall thickness than the cylinder. A design may use either or both of the top cone and bottom cylinder designs.

A building block of six female sides wherein each side of the block is adapted to accept a male side of a second different block. The first block is made up of a cross form comprised of tubular projections, a skeleton block form, and connection components connecting the cross form to the skeleton block form. The second different blocks are made up of at least four generally cylindrical projections extending normally outward from the base plate of the block that may be inserted into any of the six sides of the first block and interconnect by frictional engagement. These blocks can be interconnected and assembled into a block structure that has both a finished outward appearance in which each outermost side of every block is customizable and provides internal passageways for adding structural elements, wiring, lighting or anything else needed to run through the blocks and block structure.

A building block set having a series of blocks and screws for connecting blocks. The blocks are provided with screw holes to receive screws. The screws insert into a block and extend into a neighboring block. Some of the screws are provided with screw heads having threaded channels that are configured to receive terminal ends of other screws.

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.

A vehicle configured to move through a network of interconnected tubes includes a body, a motor, a motorized wheel, a biasing assembly, and a first element. The motorized wheel directly engages an inner surface of the tubes. The biasing assembly causes the motorized wheel to maintain continuous contact with the inner surface of the tubes during operation. A waist of the vehicle is constrained by an inner diameter (D) of the curved tube, a radius of curvature (R) of the curved tube, and a length (L) of the wheelbase of the vehicle. The waist of the body is sized such that the vehicle can freely move within any of the tubes without getting stuck therein.

A toy construction element includes a first face recessed from a second face by a recess height, a first peg extending from the second face, and an engaging member disposed on the first face. The first peg has a first peg height relative to the second face. The engaging member may include a column portion and a peg portion, wherein the column portion extends from a first end portion at the first face to a second end portion at which the peg portion is disposed. The column portion may have a column height substantially equal to the recess height, and the peg portion may have a peg portion height substantially equal to the first peg height. A toy construction element may be part of a toy construction assembly, in which an engaging member of the toy construction element connects to a hole defined by a flexible member.

The disclosed technology relates to a construction playset made of expanded plastic foam extrusions. These extrusions are assembled with or without fasteners into a wide variety of configurations and optionally the extrusions are cut safely to a desired size and in desired shapes.
