A modular wing, adapted to be used on a flying device such as a toy airplane, drone, or other small fixed wing flying device, or form a part of a wind turbine or any other apparatus that requires a wing or blade, that is compatible with all block-based toy systems such as LEGO®, DECOOL® or KAZI®. The modular wing is comprised of a series of modular aerodynamic surfaces that may be suitable for manufacture by a low-cost method such as molding or additive manufacturing such as 3D printing, typically but not necessarily from plastic, to form wing sub elements which, when assembled together, form a wing or blade such as an airplane wing or turbine blade. The modular wing may comprise cambered or symmetric wing shapes. The modular wing may be used in a static display model fully flying aerodynamic aircraft, sailing hydrodynamic boat, or aerodynamic functioning turbine.

The invention relates to a toy building element for a modular building game. The toy building element comprises one or more hollow coupling studs for coupling the toy building element to another toy building element in a releasable manner. Each coupling stud extends along a respective longitudinal axis and defines internally an axial through cavity configured to receive, in a removable manner, a locking stud apt to lock the toy building element to another toy building element coupled thereto. Each coupling stud comprises a coupling part and a receiving part for receiving the coupling part of a coupling stud of another toy building element. The coupling part comprises at least a radially flexible portion for engaging/disengaging a receiving part of a coupling stud of another toy building element. The radially flexible portion is configured to cooperate with one said locking engaging the cavity so that its radial bending is limited by the locking stud so as to prevent the coupling part from disengaging from the receiving part of a coupling stud of another toy building element.

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.

Components may be used to build a three-dimensional (3-D) model. The components can include supports and connectors. A subset of components can be selected based on the 3-D model. The subset of components can be used to build the 3-D model.

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.
