Abstract: A toy system comprising a plurality of toy construction elements, having detachably interconnecting coupling members for creating coherent spatial structures. The plurality of toy construction elements include: an energy source device comprising a housing and an energy transfer circuit therein; and energy distribution devices to provide respective external conductive loops extending outside the housing and defining a respective external energy transfer zone in a proximity of the respective external conductive loops. The energy source device is configured to be brought into operational connection with the energy distribution devices. The energy transfer circuit is configured to receive electrical energy from an energy source and, when the energy source device is in operational connection with a first energy distribution device, to energize the external conductive loops creating a time-varying electromagnetic field in an external energy transfer zone defined by the first energy distribution device in a proximity of the external conductive loops.

Abstract: A transformable modular toy element is provided. The transformable modular toy element is for use in a toy construction system comprising a plurality of modular toy elements. The transformable modular toy element comprises a body portion and a head portion. The body portion comprises one or more coupling members, the one or more coupling members being adapted for releasably coupling the body portion with modular toy elements of the toy construction system. The head portion is attached to the body portion. The head portion comprises a cavity for receiving the body portion therein. The body portion is moveable with respect to the head portion between a retracted position where the body portion is retracted into the cavity, whereby the transformable modular toy element has a first shape, and a deployed position where the body portion is in the axial direction deployed from the cavity, whereby the transformable modular toy element has a second shape. The transformable modular toy element further comprises first locking means adapted to lock the body portion in the deployed position.
