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.

The disclosure concerns a freely spliced buckle strap, at least two buckle units and a buckle connection structure; the buckle connection structure includes a clamping protrusion and a clamping groove, and a first transverse convex strip is provided on or closed to the clamping protrusion; the clamping groove is provided with a second transverse convex strip that can be matched, clamped and locked with the first transverse convex strip; two adjacent buckle units are placed in the clamping groove of the other buckle unit, and are reliably connected to form a whole through the match, clamping and locking by the first and second transverse convex strips.

A toy, game, and/or puzzle building system may comprise variously shaped connectors that are operatively attachable to other connectors or rods. The connectors may include a receiving portion adapted to receive a rod and may connect two, three, four, five, etc. rods in various angles and orientations. The connectors may include a receiving portion adapted to receive another connector. Multiple rods may be connected in 2-D and 3-D configurations and orientations. Both the rods and connectors may be provided in a variety of lengths, shapes, colors, and sizes. Additionally, the connectors may be used with any existing items, such as a plastic or wooden toothpick, straw, stirrer, and the like, that may fit within the receiving portions of the connectors. The toy picks building system may be built into a particular shape, item, vehicle, animal, person, building, scene, or landscape.

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.

An interlocking toy set comprising a plurality of interlocking pieces is disclosed herein. The interlocking pieces include a planar body having a top side, a bottom side opposite the top side, and a plurality of lateral edges that extend between and interconnect the top and bottom sides. The interlocking pieces also include a plurality of interlocking flanges that extend away from each lateral edge and configured to interlock with corresponding interlocking flanges formed on a lateral edge of an adjacent interlocking piece.

The disclosure concerns a freely spliced buckle strap, at least two buckle units and a buckle connection structure; the buckle connection structure comprises a clamping protrusion and a clamping groove, and a first transverse convex strip is provided on or closed to the clamping protrusion; the clamping groove is provided with a second transverse convex strip that can be matched, clamped and locked with the first transverse convex strip; two adjacent buckle units are placed in the clamping groove of the other buckle unit, and are reliably connected to form a whole through the match, clamping and locking by the first and second transverse convex strips.

A toy building block is comprised of a slotted interlocking brick that contains a slot for receiving planar material. The slotted toy building block may be provided in a kit with the planar material to be received within the slot. The slotted toy building block and planar material may also be provided in a kit that is contained within a package that includes one or more planar surfaces, with the planar material being removed from the one or more planar surfaces. The building block kit may also include one or more other toy building blocks that comprise interlocking bricks that are configured for attachment to a waste item.

A cost effective, structural building set, suitable as a toy, uses post connectors (10) comprised of a post (12) with attached disks (14), or similar devices that insert into cutouts (31) in geometric shaped component parts (30, 80, 180). More than one component part can be connected to the same post connector, and such component parts can rotate relative to the post axis. The connector design allows construction of stable structures of many sizes, shapes, and types, and readily facilitates hinging between different sections of such assembled structures.

A modular block toy and kit that includes a male cubic unit piece having a plurality of faces with a male node extending from each respective face of the plurality of faces, and a female piece having a plurality of faces and corners formed by three intersecting faces, the female piece having a female component formed on a respective face of each of the plurality of faces that is sized and shaped to receive a respective male node enabling connection using any side of the female piece and any side of the male piece, and in which all sides of the female pieces and the male cubic unit pieces with a snapping and interlock design are identical, enabling the pieces to be snapped together using any side of the female or male piece to achieve build out indefinitely in any direction.
