    Publication number: 20010037604
    Abstract: A louver assembly comprises a plurality of parallel horizontally extending louvers pivotally secured at their opposite ends to a supporting frame and a control bar which determines angled positioning of the louvers. The control bar has a modular construction in that it is formed by a plurality of bar segments, that interlock, vertically aligned with one another. Each bar segment pivotally connects to an associated louver such that all of the louvers move in unison through a single movement of the control bar.
