ABSTRACT:
A power-driven shutter door includes a curtain supported in a pair of tracks for bi-directional sliding movement open and closed positions, and a power drive assembly for driving movement of the curtain. The power drive assembly includes a pair of sprockets that engage shoes of the curtain, a motor for driving bi-directional rotation of the sprockets, and a control circuit including a switch movable between "open" and "close" positions for supplying power to the motor to move the shutter curtain between positions. A power-driven lock is also provided, and includes a rod supported on the curtain for movement between extended and retracted positions, a manually-operated actuator for shifting the rod between the extended and retracted positions, and a power-driven lock supported on one of the tracks and presenting a locking arm shiftable between an extended position in which the arm protrudes into the track and a relatively retracted position. An actuator is connected to the arm for shifting the arm between positions, and a circuit is connected to the actuator and includes a switch that allows control of the actuator. The curtain is locked against sliding movement from the closed position when both the rod and locking arm are extended, but is unlocked for sliding movement the rod or locking arm is retracted.
