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 automatically 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 disposed at opposite surfaces of the partition to enable accordion folding movement of the panels with the capability of the partition to be extended to a length greater than the length thereof when in fully closed position being used to "break" the panels from their flat, straight line position to a shallow accordion fold position with the hinge axes in a straight line at which point the movement of the endmost panel is reversed and inertia forces causing movement of the panels so the hinge axes cross over their straight line position. When moving the panels to closed position, the outermost panel is moved to a position with the hinge axes in alignment in which position the over-all length of the partition is greater than when the panels are in their flat straight line closed position with the outermost panel then being reversed so that inertia carries the hinge axes across their straight line position. |
