A magnet holder insert comprising a magnet and magnet holder housing designed with internal wall features capable of keeping the magnet properly positioned in the holder device, and external wall features capable of keeping the magnet holder device securely mounted in the finished part. The internal and external fastening elements of the magnet holder housing are designed in such a way as to promote rapid and secure assembly of both the magnet device and the finished part. The exposed surface of the magnet holder device can be configured with flat or dome shaped exposed contact surfaces, depending on how secure or flexible the magnetic joining feature is intended, capable of attaching to another magnet device or a material susceptible to magnetic attraction.

Dual geometry puzzles are formed of a continuous loop of polyhedrons connected by hinges. The polyhedrons include first type polyhedrons having a first geometry and second type polyhedrons having a different second geometry. Each of the polyhedrons includes at least one magnet disposed proximal to at least one face thereof. Eight of the twelve polyhedrons are the first type polyhedron, and four of the twelve polyhedrons are the second type polyhedron. The puzzles may be configurable between a first inverted configuration and a second inverted configuration. A first face of each of the first type polyhedrons may be congruent with a first face and a second face of each of the second type polyhedron.

The Letter Cubes are block to make buildings that do not just make a statement with their rooms, walls and the like, but also make verbal statements with the blocks themselves. It has a series of three-dimensional fonts made with metal, plastic, ceramic, glass, recycled materials and other materials that magnetically, with knobs, hooks, snaps and tubes (and combinations of these and other interfaces) assemble into walls, buildings and other structures that communicate messages. These alphabets also have a series of related pieces that include numbers, punctuation and additional knobs, beams and panels that enable construction of a wide range of buildings, toys, structures and objects that are artistic, toys, games and that are otherwise useful as boxes, chairs, tables, etc. The invention comes in its own box that is assembled further to the same logic as the alphabets so it does not have packaging waste.

A magnetic attraction connection structure includes a main body. The main body has a peripheral edge on which at least one connection surface is defined. The main body is provided with at least one movement space in an interior of the peripheral edge at one side of the connection surface. The movement space is provided with a magnet arranged in an interior thereof. The movement space is of a size that is sufficient to allow the magnet to move in a direction toward the connection surface or to rotate by an angle. In use, the connection surface of the main body is placed in direct contact with another main body at the location corresponding to the magnets, such that the magnets arranged in the two movement spaces automatically move or rotate due to magnetic attraction of opposite magnetic polarities, so as to securely fix the main bodies together.

The present disclosure provides a magnetic building block for connecting with other magnetic building block. The magnetic building block includes a base, a cover, at least one horizontal magnet and at least one vertical magnet. The base includes at least two vertical accommodating grooves and at least one horizontal accommodating groove. The cover is configured to connect with the base and cover the at least two vertical accommodating grooves and the at least one horizontal accommodate groove. The at least one horizontal magnet is located at the at least one horizontal accommodating groove. The at least two vertical magnets are located at the at least two vertical accommodating grooves respectively. Magnetic pole directions of two adjacent vertical magnets of the at least two vertical magnets are opposite to each other.

Circuit blocks are provided. A circuit block may include a substrate and at least one electrical component mounted on the substrate. The circuit block may also include a non-conductive frame coupled to the substrate, and at least one post coupled to the substrate and extending from the substrate and through at least a portion of the frame in a first direction substantially perpendicular to the major surface of the substrate. Moreover, the circuit block may include a contact coupled to a second, opposite surface of the substrate and including a corner section projecting outwardly from the frame and extending in at least two directions substantially perpendicular to a longitudinal axis of the at least one post. The block may also include at least one magnet positioned proximate the flexible corner section of the contact and configured to magnetically attract at least one other circuit block.

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.

A modular building block toy kit or system having a plurality of building blocks and a plurality of accessory pieces. Each of the building blocks and the accessory pieces have embedded magnets for coupling to other building blocks or accessory pieces.

Disclosed is a magnetic building block, including: a bearing body, magnetic bodies, and a retaining body, the bearing body including a sealing member and a bearing member which forms first cavities with the retaining body, the magnetic bodies being located in the first cavities and attracting adjacent external products, to form different shapes; the retaining body is in contact with the magnetic bodies to secure the same. The bearing body, the magnetic bodies, and the retaining body match for use, and the magnetic bodies are relatively fixed in an accommodation cavity through the retaining body and can be magnetically connected to the external products, such that when stacking multiple magnetic building block, different magnetic building blocks can be spliced in different surfaces and further be spliced in a suspension manner, thereby reducing a process of stacking multiple building blocks, providing convenience, and further realizing diversified splicing and meeting users' requirements.
