Claims

[Scope of utility model registration request]

A balance mechanism for changing the angle of the sprocket and louver is provided at both ends of the drive shaft located in the upper housing, and a conveyor chain suspended from the sprocket and the ends of the swinging arms lined up above and below are installed in the side housing on both sides. are sequentially connected with toggle joints, and both ends of the uppermost swinging arm are housed with an extensible body suspended from the balance mechanism directly above, and the central pin of each swinging arm is a slit provided in the longitudinal direction of the side housing. Attach a louver between the opposing center pins of the telescopic body located on both sides.
In an exterior shutter blind in which one end of the conveyor chain is connected to the center pin of the lowest swinging arm, and the louver is moved up and down by rotation of a drive shaft by a motor, the louver is lowered by the rotation of the drive shaft. A clutch is equipped with a spring that is tightened and accumulates pulling rotational force, and is installed in the middle of the rotation transmission path between the drive shaft and the motor to connect and disconnect the rotation transmission, and a reversing clutch located between the clutch and the motor. 1. An exterior shutter blind that can be opened in an emergency, characterized in that a brake mechanism for prevention is incorporated therein, and a release operation member is connected to the clutch.
