A building block, comprises a plurality of basic units and a plurality of connectors. Each connector is used to connect each two basic units. The basic unit is a hexahedron. Each face is set with a plurality of connecting holes and a slot. The connector inserts into one connecting hole on one face of the basic unit, and comes out from another connecting hole on the opposing face through the slot to connect with another basic unit. The connecting design not only increases the ways of connecting each two basic units, but also ensures that one basic unit has at least one connecting hole for connecting with another basic unit. The present invention is help to cultivate children's ability of multiple perspectives thinking and ability of 3D space thinking.

A construction system uses a comb connector element in combination with flat or generally planar polygonal shapes of various types. The comb connector elements connect to the edges of the planar polygonal shapes. Each comb connector has at least one pair of connector members. Each connector member has a proximal end connected to the polygonal member, and a distal end. Each connector member having a face portion that includes a recess extending from a central region of the face portion. The recess extends to the distal end of the face member.

An electronic building toy component having a main body having opposing top and bottom surfaces and a thickness and having wiring between the top and bottom surfaces and having a connecting feature at a peripheral edge of the main body. The connecting feature, such as a plug or receptacle that is compatible with other electronic building toy components, allows the electronic building toy component to be electrically coupled with other electronic building toy components, such as batteries, Bluetooth enabled hubs, lights, buzzers, motors, sensors, and other electrical connecting building components. Some components also include slots and taps for engagement with compatible features on other building toy components for mechanical coupling. A Bluetooth enabled hub also allows remote control of electronic building toy components using Bluetooth enabled devices, including smartphones and tablets.

An apparatus and method provide a tower house assembly that may be reconfigured to provide essentially an infinite number of configurations. Floors may be reshaped. Interior and exterior walls may be added or removed, including sections with doors and windows. Multiple-story assemblies may be constructed with each additional story supported by the one below. Complex roofs may be constructed and placed atop each story. Such roofs and stories are easily removable to view the interior scene. However, when removed, the roofs and underlying stories retain their shape due to roofs and floors being joined together by biscuits. Floor sections may be further connected by edge connectors about the perimeter of a floor section.

An interlocking building block system is disclosed. The system may include a first building block, a second building block and an elongated connector. The first building block and the second building block may include a first recess and a second recess, respectively. The elongated connector may be configured to connect the first building block and the second building block. The elongated connector may include a first portion and a second portion connected to each other. The first portion may be configured to be inserted in the first recess and the second portion may be configured to be inserted in the second recess. Each of the first portion and the second portion may include an elongated wall and side walls. The elongated wall may include an elongated ridge at an elongated wall center portion disposed along an elongated wall length.

An interlocking building block system is disclosed. The system may include a building block and an elongated connector. The building block may include a recess on a building block face. The elongated connector may be configured to connect with the building block. The elongated connector may include a first portion and a second portion connected to each other at an intersection line or a throat portion. The first portion or the second portion may be inserted in the recess. Each of the first portion and the second portion may include an elongated wall and side walls. The elongated wall may be slanted towards the throat portion such that a center point of the elongated wall is closer to the throat portion than side edges of the elongated wall.

A 3D fort building kit is a device that can create a variety of structures and shapes. In other words, the device has improved materials and designs with better qualities, that enables kids to build complex 3D structures. To accomplish this, the device includes panels, connectors and utility features that help kids to construct and assemble a structure of their choice in many designs. Further, structures may be constructed in many creative designs by allowing the panels to be connected vertically, horizontally, and at any angle. Furthermore, the constructed structures can be disassembled and constructed again to build other designs safely by kids. Additionally, the device is simple, durable, and light weight enough for young kids to build stable and versatile structures of their choice.
