ABSTRACT:
This invention relates to a louver shutter with movable louver boards in which a set of adjustable louver boards capable of opening and closing are aligned in one side, the upper part, or lower part of the panel of a louver shutter or door, thereby to permit good ventilation, lighting and shielding of the room, to serve security purpose, and to prevent entry of rain water and harmful insects into the room. This invention provides a very practical and inexpensive louver shutter of simple mechanism which is sturdy in construction, easy to operate, and can be mass-produced, without any disadvantages encountered in conventional ones as disclosed in U.S. Pat. No. 3,991,518.
