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.

An adhesive strip includes an array of apertures that provides additional retention of interlocking bricks. The adhesive strip can include a carrier material. The carrier material can include a plurality of evenly spaced and evenly sized apertures in an array of at least two columns by two rows. The carrier material can include a first carrier material side. The carrier material can include a second carrier material side on an opposite side of the carrier material from the first carrier material side. The adhesive strip can include a pressure-sensitive adhesive coating arranged on the first carrier material side.

A pairing block set has a right-hand toy block and a left-hand toy block, each of mutual, mirror symmetry and optionally incorporating a system of eight abutment points to each engaged studs on its mating block upon assembling. By providing two different layouts—one for the odd number, and one for the even number tier toy block groups respectively, using a combination of the pairing block set and other commonly seen basic type of blocks for each tier groups, and after stacking up tiers of block groups by different layouts alternatingly, in a tier-to-tier mutual interlocking manner, a structurally sound assembly of an oblique sided structure can be built with smoothly lined sides or walls. A plurality of latches is left at both ends of the assembly, to be further interlocked with its neighboring, mating toy blocks of the intended final structure.

A play mat system to which various objects may be removably mounted over a display. The play mat system generally includes a housing having a transparent upper surface or upper cover. A display is either integrated with the housing or provided by an electronic device such as a tablet computer which may be removably connected to the lower surface of the housing via one or more receiver brackets. The housing may include a plurality of projections extending from its upper surface or upper cover to which various objects such as toys or building blocks may be removably mounted. Multiple housings may be interconnected via links such that they function as a singular display unit.

A game system comprising a data processing system and an identification toy element that includes information associated with the identification toy element; wherein the identification toy element is a toy construction element comprising one or more connectors configured for mechanically connecting one or more other toy construction elements to the identification toy element so as to allow a user to construct a toy construction model; and wherein the data processing system is configured to: detect a presence of the identification toy element in a detection area; create an association between a virtual object in a virtual environment and the detected identification toy element; access, when the identification toy element is again placed within a detection area, the information associated with the identification toy element; obtain, based on the accessed information, information about the virtual object associated with the identification toy element; present a representation of the associated virtual object; and to perform a play pattern procedure including controlling the representation of the virtual object.

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.

Aerophone toy building blocks to make a plurality of combination of sounds comprising of a plurality of building blocks, each the block having four walls, a top lid and a bottom cap to make a body having an inner space; at least two of the walls, the lid and the cap having releasable couplers; each the block having aerophone musical instruments to produce sounds; each the block having a plurality of airway channels inside the inner space, the airway channels are connected to the adjacent airway channels; the blocks having the same or different sizes, whereby larger blocks create lower pitched sounds, while smaller blocks create higher pitched sounds; the blocks having the same or different materials to let the instrument produce different sounds; the musical instrument being mounted either onto or inside of the body of the building block, or being permanently encased within the material of a block; and an air source to be attached to the plurality of building blocks to provide an air flow to each aerophone instrument.

Embodiments provide a toy construction element having an outer shell and moving members that can extend from and retract into openings in a face of the outer shell. The toy construction element may have a plurality of pegs for attaching to other engagement elements (e.g., blocks or figurines) and the openings may each be centered with respect to a 2×2 arrangement of pegs on the face. The moving members may be in contact with an actuating member, e.g., opposing arms of a rocking member. As one moving member is pushed down the rocking member may lift the other moving member. Upon attaching an engagement element to the toy construction element, one moving member can be pushed down to force up the other moving member so that the engagement element is released. Other actuating members may be used, such as push-rods or camshafts.

A circuit building device and method for use. The circuit building device is configured to resemble a construction-style brick including various knobs and receptacles for cooperating engagement. The shape and features of various specialized bricks and hubs allows for improved circuit construction and learning.

The present invention relates to a fitting system, and more specifically to an interlocking connection system that comprises at least two elements or two parts that can be joined together and separated from one another easily (interlocked and unlocked), in which all of the parts of said system must have at least one unit comprising a male connector and a female connector simultaneously in the same part, and must ideally have similar additional fasteners that are positioned inversely when connected (mirrored) and are also proposed in this application in order to improve the fastening and stability of the interlocking. This fitting system can be coupled to various products such as storage recipients or packages in various areas (cosmetics, foodstuffs, pharmaceuticals, etc.).
