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 holes the panels in both a closed position and an open position. The control mechanism also limits the movement of the panels toward closed position and transmits an opening force from preceding panels to succeeding panels when being moved in opening direction of movement with the control mechanism including a unique combination of control base, control lever, control plate, control cam, control cam follower and control cam string to obtain the desired multiple functions. |
