Abstract
A modular assembly for an indoor shutter includes fully functional louvers and is assembled from extruded and/or injection molded plastic components designed to provide complete symmetry to the assembly, both side-to-side and botom-to-top. Two identical bottom (or top) half frame members are secured together with a pair of connector members. A pair of side rail channels are slid down over the ends of the bottom frame members and enclose the connector members therein. A pivotal louver and a pair of louver supports are alternately slid into the side rail channels with the louver pivots captured between cylindrical notches on the upper and lower faces of vertically adjacent louver supports. The top frame member is connected and closed off in the same manner as the bottom frame, utilizing identical components.
