A toy building set is disclosed that describes a building piece having a rectangular base, a closed end piece and an open multi-cylindrical end piece such that the building pieces are used to create structures for play by children, such as doll houses. The open multi-cylindrical end piece includes a set of hollow cylinders having a narrow opening that run the length of the cylinder for attachment with a closed end piece of a second building piece. The open cylinders are attached to a building block base at varying angles to create desired play structures.

A joint for modular furniture includes a first panel joined to a second panel with a slot and a tab. The slot and tab are formed with complementary faces which are angled to prevent delamination of anisotropic materials such as plywood.

An insert-and-twist building block structure includes a connection bar and a connection terminal unit. The connection bar has an end from which a combination projection section extends and has a conic shape. The combination projection section has an external circumferential surface formed with a bead ring including multiple raised beads intermittently arranged in a ring configuration. The connection terminal unit includes a connection terminal having an end inward recessed to form a combination cavity in a conic shape. The combination cavity has an internal circumferential surface formed with a groove ring including multiple recessed grooves intermittently arranged in a ring configuration. The recessed grooves each a middle portion forming a deep trough section and two ends each forming a shallow trough section, and a depth is decreased from the deep trough section toward the shallow trough sections.

A tile game system is provided that includes a plurality of two-dimensional and three-dimensional components. The two-dimensional components can include a plurality of modular tiles provided in various sizes and configurations that can be joined together to form a grid-based gameplay area. The three-dimensional components can include external boundaries for the gameplay area, internal boundaries, terrain elements such as columns and staircases, and game figures. According to aspects of the present disclosure, the external and internal boundaries can be provided with recessed sections that allow a game figure to be contained within a single grid square and prevent the grid of the gameplay area from becoming warped. According to some aspects of the present disclosure the internal and external boundaries can be illuminated and provided with removable and interchangeable light-permeable skins that allow a user to switch between various illuminated designs.

The disclosed technology relates to cutting foam logs in a construction toy to a desired angle with a toy saw and a variable angled miter. The logs are then able to bend from their initial straight shape to the same angle as the angle of the wedge removed from the log. The cutting of these angles with the angled miter makes the angle of the wedges to be cut predictable and repeatable.

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.

Provided herein is a set of card-like structure and connector toys for building; the set comprising one or more card-like structures and one or more end cap connectors, wherein the one or more end cap connectors comprise one or more slots for inserting the card-like structures. Also provided herein is a connector toy or a kit of connector toys; comprising one or more slots for inserting card-like structures for building.

Embodiments include a construction toy kit having component parts capable of being assembled in a configuration chosen by the user. The kit may contain a connector extending from a first end to a second end, having a securement comprising a first retainer feature, a second retainer feature and a third retainer feature. The connector may further have a first grip extending from the first end toward the securement, where the first grip is sized to receive a feature of a building panel. The kit may also contain a multiple building panels of various configurations, a mat used as a base for erecting a structure and multiple sensor components. These components among others may be assembled to create structure such as a race course for robotic toys. The sensor elements may be implemented by the user to sense various actions of the robotic toy, and respond as chosen by the user.

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.
