Abstract: A folding partition having two rows of spaced, pivotally associated rigid panels supported by a trackway or the like with a control mechanism providing movement of the panels from a flat aligned condition when the partition is in closed position to an open position in which the panels are oriented in opposed surface-to-surface stacked relation generally in perpendicular relation to the position of the panels when in closed position. More specifically, a control mechanism interconnects the panels and biases the panels toward both a closed and open position for assisting in the opening and closing movement of the flat folding partition and holds the panels in both a closed position and an open position.
