The invention relates to a modular education and toy block having at least one piece 10 having a body (11), a jointer (20) working with comb fitting principle (finger joint), having recesses and/or protrusions that each of them is in triangular on at least one surface of the joinder (20) which is appropriate to form new pieces (10) by combining the piece (10) with another piece (10).

The invention describes a new constructor module with the additive aspects of sound and dynamic construction. A base block is provided with varying mating elements for adjustably connecting structural blocks and plates together with sounding elements. A plurality of base blocks may be constructed based on desired output in various shapes and structures. The base blocks are coupled together with connecting elements and fixing pins, which also assist in coupling the sounding elements. Additional plates are also utilized for creating dynamic sounds and structures, including D-shaped plates and U-shaped plates. Constructor set modules may utilize all such elements in a plurality of structures, or at minimum, only base blocks, connecting elements, a sounding element, and fixing pins.

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.

A coupling for assembling at least two beverage cans together, comprising at least a pair of collar portions, each to slidably receive a corresponding end region of one of the beverage cans, the collar portions being configured to engage the beverage cans for associated games and/or other amusement activities.

Assembly of two construction elements (1) which each comprise a number of side faces and are provided with a connecting means (2) for connecting the construction elements (1) to one another. The construction elements each comprise a side face with a recess (3), the recess (3) having been produced by cutting away a part (4) from the construction element (1). The slidable parts (4) are slidable in the recesses (3) and form the connections (2). A method of connecting such construction elements (1) to one another is also provided.

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.

According to one embodiment, a modular toy assembly system featuring one or more bases and a plurality of posts. Coupled to recessed connectors of the base, the plurality of posts includes a first end connector and a second end connector for coupling to different bases to provide depth of the toy. The posts include a first elongated body element and a second elongated body element interposed and extending between the first end connector and the second end connector. The first elongated body element and the second elongated body element are oriented to produce (i) a first slot between a first side of first elongated body element and a first side of the second elongated body element and (ii) a second slot between a second side of first elongated body element and a second side of the second elongated body element.

A system comprising a plurality of blocks is disclosed. Each block has a cuboid body and a connecting member extending away from each corner of the cuboid body, such that for each connecting member there is a first opposed connecting member, a second opposed connecting member and a third opposed connecting member, and a connector engagement arrangement is defined between a connecting member and each of the first, second and third opposed connecting members. The system also comprises a plurality of connectors, each connector having a body with a first connection end for engagement with a connector engagement arrangement of a first block and a second connection end for engagement with a connection engagement arrangement of a second block so as to connect the first block to the second block.

The application relates to a field of object connection and in particular, relates to a basic connecting block and a connecting block group. The basic connecting block includes a connecting block body, wherein at least one protrusion corner is provided on one side of the connecting block body and same number of inward recesses as the protrusion corner are provided on an opposite side of the connecting block body, and wherein a surface contour of the protrusion corner is consistent with that of the inward recess, the protrusion corners are connected with each other and the inward recesses are communicated with each other.
