Most children's construction sets fail when to comes to providing children with a fast and easy way to build large structures, such as houses and forts. They fail because the methods they use to connect the pieces of the set are not feasible, don't enable the children to build large structure, or quickly damage the pieces themselves. This application represents years of refinement to produce a novel turn-key design that makes it very easy for children to build such structuresor any other large objects they can imagine. The novelty of this approach includes a slotted Connecting Element that users can slip between cutout made in the edges of Planar Elements. The user inserts the Connecting Element, lines up the slots on the element with the edges of two adjacent Planar Elements, and then rotates the Connecting Element approximately 90 degrees to connect said Planar Elements using friction and compression.

A hollow rigidly deformable geometric toy with a flat side and a mating joint construction. The toy has a plurality of faces which form a geometric cage and a plurality of apertures, and can contain an interior toy. The geometric toy is stably constructed such that it is safe for babies and children and suitable for teething and play.

A construction set includes one or more hubs and a plurality of tubular struts. Some of the hubs include a central aperture to receive a length of a tubular strut. Some of the hubs include one or more strut coupler prongs arranged radially about the central aperture. Some of the hubs include a central slot adapted to receive a portion of another hub such that the connected hubs are secured at right angles relative to one another.

The present invention relates to assembly blocks which can freely be coupled into various text arrays and creative shapes by means of insert-coupling or slide-coupling of a first block and a second block which can be manufactured from a lightweight material.

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.

An interlocking rotatable assembly includes multiple interlocking pieces. Each of the interlocking pieces has a disk, a center hole formed through a center of the disk, a mounting slit radially formed in a peripheral edge of the disk, two arms, and two engaging protrusions. The arms parallelly protrude from the peripheral edge of the disk and are oppositely disposed beside the mounting slit. The engaging protrusions protrude from the arms respectively. No undercut is formed on each of the interlocking pieces. Therefore, only a female die and a male die are needed when manufacturing the interlocking pieces by injection molding process. Molds and manufacturing process for manufacturing the interlocking piece are simplified. Accordingly, mold cost and manufacturing cost of the interlocking piece are reduced, and defect-free rate of the interlocking piece can be increased.

A ring combination toy includes plural assembling bodies which are ring structures, each having plural first connecting portions; and plural assembling pieces, each having two connecting structures and a bent portion, and the connecting structures are connected by the bent portion to form the assembling piece, and each of the connecting structures has a second connecting portion corresponding to the respective first connecting portion. When the second connecting portions of any one of the assembling pieces is engaged to the first connecting portions of any two of the assembling bodies respectively, the assembling bodies are combined with the assembling pieces. Through the design of different shapes, the young children will not be injured easily while playing the game, and the parents can be assured to let their young children play the game and have fun freely.

Provided is a toy block that can be freely connected and rotated, and can be fixed to maintain a certain angle at a specific position, thereby maintaining a specific posture or shape.

An interlocking toy building block has a block body, projector assembly and film. The block is formed within interconnecting building elements thereon for connection with other toy blocks, and a projector opening is defined in a side of the block body. The projector assembly includes a lens arranged in the projector opening, a light source arranged in the block body to direct light outside the block body through the lens and projector opening, and a power assembly supplying electrical power to the light source. The film having an image thereon, the film arranged in the block body between the light source and the lens, such that the image on the film is projected externally from the projector opening by the light from the light source passing through the film and the lens. The film can be in a removable cartridge and the lens can be included in a focusable assembly.
