A building blocks that can be easily assembled or disassembled, comprising a building block main body. Each side of the building block main body is configured with a connecting structure. A plurality of building block main bodies is joined together through the connecting structures. The connecting structure comprises a connecting seat and a connecting rod. The connecting seat has an open connecting slot. The inner walls on the two sides of the open connecting slot are both formed with positioning bumps. The two sides of the connecting rod are respectively configured with a first and a second positioning slot. The two sides of the connecting rod are further configured with a first and a second guide slot that are respectively communicated to the first and the second positioning slot.

A stack and nest toy is provided. The toy includes a plurality tube sections that each comprise a scaled variant of a matching shape such that a first of the plurality of tube sections is scaled to nest around a second of the plurality of tube sections. The second of the plurality of tube sections is scaled such that a respective outer surface of a bottom portion thereof is configured to interlock with a respective inner surface of a top portion of the first of the plurality of tube sections and, when the first of the plurality of tube sections is interlocked with the second one of the plurality of tube sections, an orientation of the first of the plurality of tube sections is rotationally different from an orientation of the second of the plurality of tube sections.

A toy comprising a frame and an inverting toy. In some embodiments, the inverting toy includes an invertible shell having a first surface and a second surface, the invertible shell configured to protrude outward in a first direction with respect to the frame until a depressing force on the first surface or the second surface in a second direction causes the shell to invert and protrude in the second direction with respect to the frame, wherein the first direction and the second direction are substantially opposite, an edge member formed at an edge of the invertible shell and configured to secure the invertible shell to the frame, and a pulling member formed on and protruding outward from the first surface of the invertible shell.

In a system having multiple coupling elements configured for single-handed coupling and single-handed de-coupling, each coupling element includes a body portion defining an opening and having a base configured to be free-standing. The body portion has an outer limb defining a hook member and at least one slot formed therein, the respective slot of a second initially free-standing coupling element being accessible to the respective hook member of a first suspended coupling element or vice versa. The coupling elements being configured so that mutual points of contact between the first and second coupling elements are maintained during both lifting and lowering the second coupling element thereby facilitating a one-handed intercoupling or decoupling operation with respect to a free standing coupling element disposed upright on a horizontal support surface.

Implementations described and claimed herein provide systems and methods for delivering a customizable feedback stimulus. In one implementation, a custom feedback device comprises a shell housing having a first shell and a second shell. The shell housing opening extends between an outer surface of the first shell and an outer surface of the second shell. A plurality of protrusions extends between the first shell and the second shell, and at least one receiving area is defined by the plurality of protrusions between the first shell and the second shell. The receiving area is adapted to house a customized portion.

A construction system having construction elements is provided, which allows for unlimited designs of producible structures to be created. If the construction system is provided as a toy, then the construction elements can be played with without suffering fatigue. Furthermore, the producible structures are sufficiently resilient and can thus be used as a ball, for example. The construction elements can be manufactured in a simple and low-cost manner.

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.
