A tooth-meshing rolling toy set includes at least one curved carrier member and at least one rolling member. The at least one curved carrier member has a first surface and an opposite second surface; and the first and the second surface all are provided with a toothed structure having a plurality of teeth. The at least one rolling member includes a rolling body having a peripheral surface extending around the rolling body to define a closed geometric loop having a curved surface. The peripheral surface is also provided with a toothed structure having a plurality of teeth that mesh with the teeth of the toothed structure on the curved carrier member, such that the at least one rolling member can roll on the first surface or the second surface of the at least one curved carrier member through meshing with the at least one curved carrier member.

A structure for coupling assembly blocks of a polyhedral shape formed of a plurality of side plates, a top plate, and a bottom plate, includes a first coupling member formed on a portion of at least one of the plurality of side plates, the top plate, and the bottom plate and a second coupling member formed on a portion of at least one of the plurality of side plates, the top plate, and the bottom plate other than one on which the first coupling member is formed. The first coupling member of one assembly block is configured to couple with the second coupling member of other assembly block in a sliding manner, in a fitting manner, or in a rotating manner.

The present invention relates to a cubic element for construction toys, including three, straight, open-ended channels each formed on an adjacent different face of the cube between two opposite faces of the cube and extending in orthogonal opposite directions to each other (X,Y,Z). Each channel includes a bottom wall and two upwardly extending parallel sidewalls, wherein the width of the bottom wall and the distance between the face which is distal to the channel that is extending orthogonally from the same cube face, and the sidewall adjacent the distal face, are substantially equal.

A construction toy is disclosed. The construction toy comprises at least one prismatic or cylindrical housing with a closed end and an open end, with two or more connection means located on an external surface between the open end and closed end. The construction toy may further comprise an ornamental component, stickers, a motion activated illumination arrangement resulting in numerous modes of play of the construction toy. Multiple housings of the construction toy act as building blocks. The construction toy acts as a means to collect, display and store numerous ornamental components. The construction toy can be customised with stickers which can be revealed and hidden using a motion activated illumination arrangement comprising an infrared sensor and UV light.

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 block may comprise a base comprising a first block side comprising a first side plane and a connective protrusion coupled to the base and extending distally outwardly and substantially perpendicularly from the first side plane. The connective protrusion may comprise a center pillar coupled to the base extending distally outward from the first side plane, a base portion coupled to the center pillar and the base and extending axially and substantially perpendicularly from the center pillar in a first direction, and an overhang portion coupled to the center pillar extending axially and substantially perpendicularly from the center pillar in a second direction opposite the first direction such that there is an overhang space between the first side plane and the overhang portion. The block may further comprise additional connective protrusions, and the connective protrusions of multiple blocks may enable the coupling of such blocks.

A construction toy set comprising a plurality of construction pieces is disclosed herein. Each construction piece of the plurality of construction pieces includes a planar body having a top surface and a bottom surface opposite the top surface and spaced apart relative to the top surface.
