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.

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.

Embodiments may relate to a foldable play structure which may be easily assembled and which may be form of four or more panels each connected to another to provide an accordion fold structure; corner hinges comprising a first hinge portion attached to one panel of the at least four panels; a second hinge portion attached to another panel of the at least four panels; and a fastener configured to be retained within either the first portion or the second portion; and mid-wall hinge(s) attached to two of the panels and located between the corner hinges. Typically, in a first configuration, the panels of the accordion fold structure are folded to be stacked in substantially parallel planes, and in a second configuration, the panels are unfolded forming a play structure. The retained fastener may be used to secure the corner panels together.

A structural element is formed of at least one foldable blank. The structural element has side walls, at least one partition that extends between at least two of the side walls and at least one pair of flaps, each of the flaps in the pair of flaps being formed by an edge part of the foldable blank bent inwards the structural element. The flaps in each pair are adjacent to each other and coupled with the partition by notches. The partition is located in a plane which is not parallel to planes of the sidewalls.

A stackable track assembly and method for stacking a booster and/or track frame is disclosed. The stackable track assembly includes a base, a track portion disposed in the base, and a frame extending out of the base and laterally across the top of the base. The stackable track assembly further includes a tab and slot for laterally coupling two track assemblies. The stackable track assembly further includes a receiving member and engagement member for vertically and/or laterally coupling two track assemblies. In some implementations, the track assembly may include a booster for accelerating a toy vehicle.
