Abstract

A base for a modular multi-part construction toy is disclosed which has a surface which permits the assembly of a number of toy modules thereon to form an erected toy. The base further includes a number of mechanically movable elements which are used in association with various drive shaft pieces to rotate or otherwise move part or all of the erected toy. The drive shaft pieces are engaged by the movable elements which in turn are driven in movement by gearing mechanically coupled to a motor which is housed internally within the base. The base further includes a number of electrical receptacles for supplying electric power to electric light emitting toy modules, and an audio output mechanism for producing sounds associated with the erected toy. The surface of the base may further be provided with a desired contour or profile and have indicia which simulates a particular geographic location, vehicle, vessel, or other structure.
