Abstract

The present invention is in a swivel shutter that incorporates louvers that are pivotally mounted in a rectangular frame that is formed by joining, at their ends, top and bottom rails with left and right stiles. The louver pivotal mounting includes fixed and retracting conical shaped pivots that are individually fitted as aligned pairs or are arranged as bars of joined pivot sections into appropriate holes or slots in the left and right stiles. The individual pivots are for fitting into conical shaped holes that are formed in louver ends, the pivot of each retracting pivot to retract against a spring biasing into and below the level of the stile side, allowing a louver end hole to be aligned therewith. The invention further includes a tilt rod for mounting across aligned louver ends to simultaneously pivot the louvers between open and closed attitudes and a system for applying, to each louver faces, a section or sections of a flexible material as a veneer.
