Abstract
A door for use in a building, which includes a door frame defining an opening, and a louver arranged in the opening of the door frame. The louver includes a plurality of slats aligned parallel to each other. Each of the slats is connected at its opposite ends to the door frame so that the slat is pivoted about an axis generally coincidental with its centerline. The door also includes an adjusting assembly for pivoting the slats, and a connecting member for connecting all the slats. The adjusting assembly includes a rotatable lug member connected to one of the slats so that the slat is pivoted when the lug member is rotated. Due to the connecting member, the slats are simultaneously pivoted in the same direction when one of the slats is pivoted.
