Abstract: A multi-strand chain forms a chain drive including at least two chains so that the chain drive may communicate a force when the chain is pushed or pulled. The chains maybe separated or disengage so as to be stored compactly. The chains may be engaged to form the chain drive so that the chain drive is substantially rigid and in a linear orientation, and pivotally connected chain links may not substantially rotate relative to each other and may not be deflected substantially from the linear orientation. The chains may be engaged and disengaged by rotating around sprockets which deliver the force to the chain drive. The chain drive may be utilized as a garage door system for raising or moving laterally a garage door or movable barrier with the chain drive in compression.
