ABSTRACT OF THE DISCLOSURE An electrically operated folding partition including a plurality of pivotally interconnected panels movable from a straight line, flat, closed and locked position to an accordion folded stacked open position in which the control system will auto- matically move the partition panels from their closed position to their open position or from their open position to their closed position upon actuation of a suitable control switch or the like. The panels are pivotally interconnected by hinge structures with the hinge axes being alternately disposed at or near opposite sur- faces of the partition to enable accordion folding movement of the panels. When moving the panels from their closed to their open posi- tion, the capability of the partition to be extended to a length greater than the length thereof when in fully closed flat position is used to "break" the panels form their closed flat position to a shallow accordion fold position with the hinge axes falling along a straight line at which point the movement of the endmost panel is reversed and inertial forces cause movement of the panels so the hinge axes cross over their straight line position. When moving the panels from open position to closed position, the endmost panel is moved to a position with the hinge axes in alignment in which posi- tion the over-all length of the partition is greater than when the panels are in their flat straight line closed position with the endmost panel then being reversed so that inertia carries the hinge axes across their straight line position.
