Patent ID: 8826593

Claim:
A louver module, comprising: a frame having horizontal frames and vertical frames assembled in a rectangular shape; an opening/closing mechanism assembled with any one of the vertical frames so as to provide torque; a louver unit made of a synthetic resin material and including a plurality of louvers each having a compartment forming an air layer for heat resistance therein, wherein symmetrically-shaped brackets are respectively coupled to both ends in the length direction of the respective louvers, a reinforcing beam extended in the length direction is assembled inside each louver of the louvers, at least one surface of outer surfaces of each louver of the louvers has a curved surface, and the plurality of louvers are rotatably mounted between the vertical frames constituting left and right sides of the frame while being horizontally spaced apart in vertical direction from one another; and a power transmission mechanism including a plurality of holders respectively disposed at positions corresponding to end portions of the louvers inside the vertical frames constituting the frame and a pair of shafts disposed inside each vertical frame of the vertical frames, wherein each holder of the holders has one surface on which a fixing projection is formed and the other surface on which a pair of link projections are formed, the fixing projection of the holder is coupled to the end portion in the length of the reinforcing beam by passing through the vertical frame and a bracket of the brackets, corresponding to the position of the fixing projection, the link projections of each holder of the holders are linked with the respective shafts, and the end portions of the pair of link projections of a specific holder corresponding to the mounting position of the opening/closing mechanism are mounted to the opening/closing mechanism by passing through the linked shafts, wherein the torque is transmitted to the specific holder from the opening/closing mechanism, the pair of shafts are driven in opposite directions to each other by rotation of the specific holder so that the torque is transmitted to other holders, as the holders inside the vertical frame forming one side of the frame are rotated, the torque is transmitted to the louver to be rotated, the holders inside the vertical frame forming the other side of the frame are rotated in connection with the rotation of the louvers coupled to the respective holders, and the pair of shafts inside the vertical frame forming the other side of the frame, which are linked with the holders, are driven in opposite directions to each other.
