The invention relates to a method for assembling an arrangement. The invention also relates to a corresponding assemblable arrangement. For the arrangement according to the invention, there are at least two groups of individual elements and each group comprises at least two individual elements. For each group of at least two elements within one group of elements, the at least two elements can be fitted together. Further, the at least two elements of one group can be fitted together with at least two elements of another group. Each group of elements forms a layer of the arrangement. The arrangement, when assembled, forms a three dimensional object.

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).

A building toy and a method of building with it. The toy is designed to be constructed of a rigid and generally non-deformable material such as, but not limited to, wood and particularly hardwood, and is constructed in the fashion of a log-style building toy. The toy utilizes interconnecting notches in its construction, but provides for a variety of specialized pieces which allow for interconnection of parts where there is one notch but not another, as well as the ability to build roofs, floors, and specialty structures such as fireplaces through the use of specialized components. Further, the use of more strongly connecting components allows for stronger structures to be built.

A flexible building segment includes a first outer-section, a second outer-section, a central-section, a first ribs-section and a second ribs-section. The first outer-section includes a first magnet embedded therein. The second outer-section includes a second magnet embedded therein. The central-section includes a central magnet embedded therein and at least two central attachment slots at opposite sides thereof. The first ribs-section includes a first flexible portion and respective ribs. The first flexible portion couples the central-section with the first outer-section. The ribs, respective of the first ribs-section, are attached to the first flexible portion and parallel to each other. The second ribs-section includes a second flexible portion and respective ribs. The first flexible portion couples the central-section with the second outer-section. The ribs, respective of the second ribs-section, are attached to the second flexible portion and parallel to each other.

The present invention relates to a construction toy with interlocking tile-shaped pieces. Each tile-shaped piece has at least two interlocking elements on each side. One element is a male mating portion and the other is a female mating portion, so that each side of any tile-shaped piece is hermaphroditic in relation to any side of another piece, and the pieces can be locked to each other to form a two-dimensional and three-dimensional construction. The tile-shaped pieces must be oriented in the same plane for the interlocking elements to lock. Each interlocking element has a sphere-shaped configuration on a cylindrical stem that is connected to the side of the tile-shaped piece. The male mating portion has a convex configuration as a function of the interlocking element's spherical shape, and the female mating portion is a concavity in the interlocking element that mates with the male portion to lock interlocking elements together.

Disclosed herein are toy building units of a toy building set. The building units comprise a sheet of a material that defines a net of a polyhedron, the sheet having a plurality of sections, each section being connected to another section with a hinge. The building units are configured to fold at the hinges from a flat configuration into a polyhedron with a hollow interior. The building units also comprise a plurality of joins on outer edges of the building unit, each join comprising one or more teeth configured to interleave with teeth of another join and releasably connect the sections of the building unit to form edges of the polyhedron. The sections, hinges and joins are all provided on one piece of the same material.

A magnetically connected toy block comprises a toy block body (10), a magnet fixing sleeve (20), and a magnet. The toy block body (10) is provided with a sleeve pipe (11) with an opening at the upper end, and the magnet fixing sleeve (20) is fixed in the sleeve pipe (11). The upper side and the lower side of the magnet fixing sleeve (20) are respectively provided with a slot (21) and a socket (22), the slot (21) is located on the outer side of the sleeve pipe (11), and the socket (22) is located on the inner side of the sleeve pipe (11). The upper end of the slot (21) is closed, and an opening is formed on the lateral face of the slot (21). The magnet comprises a first magnet (31) and a second magnet (32), the first magnet (31) is disposed in the slot (21), the second magnet (32) is disposed in the socket (22), and the polarity directions of the first magnet (31) and the second magnet (32) are the same. Mounting of a magnet enables a toy block to be firmer, and the toy block can he used more safely.

The present invention discloses a variety combining block which comprises: a first block unit and a second block unit; wherein the second block unit joints to a through hole of a center of the first block unit; the peripheries of the first block unit and the second block unit are respectively provided with grooves, and the first block unit cannot only joint to each other, the first block unit or the second block unit can also joint to each other by grooves on peripheries thereof.

In one embodiment, an article of manufacture includes a plurality of nestable, identically sized building blocks, each block having at least one inward-slanting side wall connected to a top surface of the block at an edge of the block, wherein a first block defines a hollow interior space adapted to receive a second block in a nested configuration. One or more of the blocks have one or more recesses on the top surface that are each designed to receive a portion of the bottom edge of another block, thereby providing increased stability for non-nested configurations. A recess may have a curved shape that can receive a curved portion of another block at different angular orientations of the blocks. The recesses may engage another block's bottom edge in a non-interlocking manner or in an interlocking manner.
