ABSTRACT:
A louver assembly is provided which includes a frame having vertical side jambs, a head, a sill, and a central opening. A plurality of vertically-spaced, substantially-straight horizontal louver members extend across the opening between the side jambs, with each of the louver members including a closing section and an actuating section. Actuating means are attached to the actuating section of each of the louver members for actuating them between open and closed positions. In addition, sealing fins extend from the jambs, head, and sill to cover the peripheral portion of the central opening. Each of the louver members is pivotally mounted on the side jambs, so that when the louver members are in their closed positions, the louver members overlap the peripheral sealing fins, and the closing section of adjacent louver members overlap each other to tightly seal the louver assembly against inclement weather. Further, each of the actuating sections of the louver members form troughs directed to the exterior for drawing away any water which may penetrate the seals. In addition, the side jambs and the sealing fins cooperate with the louver members in their closed positions to form vertically-extending drainage channels connecting the troughs to provide additional drainage of water to the exterior. Finally, the louver members are pivotally mounted off center, with the closing section being larger than the actuating section. The closing section only is exposed to the exterior, such that exterior wind conditions tend to close the louver members more tightly.
