Abstract
A chain drive mechanism, especially for a construction toy system, is assembled with individual U-shaped chain link elements. The chain link elements are notched at their open ends and provided with bearing portions at their closed ends. The notched open ends are arranged for snap-fit attachment over the bearing portions of adjacent links, enabling a flexible chain of any length to be easily assembled. Drive pins, preferably coaxial with the bearing portions, project outwardly from each side of the chain links and are engagable with grooves of spaced-apart drive wheels, collectively forming a sprocket assembly. The drive wheels can be individual gear elements otherwise used in a toy construction system for gear drive mechanisms. The base portions of the U-shaped link elements are grooved transversely for the snap-fit attachment of construction toy connector parts, allowing the chain elements to carry other components.
