Abstract: A shutter is manufactured by laminating top and bottom surfaces of a substrate material. The substrate material is then cut in bulk, forming strips that are shaped, sanded, edge-laminated and cut to length so as to create prefinished shutter components. These components are then assembled into a completed shutter. The laminates provide a high gloss, piano finish that is more scratch resistant and easier to clean, dust and maintain than spray-painted coatings used on conventional shutters. Tongue and groove joint construction reduces component chipping and cracking and provides significantly more surface glue space than conventional doweled joints. Also, louver tension control anchors prevent warping and bowing of the shutter frame and will not strip out of the louvers as would conventional tension controllers using “screw into wood” construction.

Abstract: Several embodiments of the shutters employ a variety of synergistic features which may be used individually or in combination to produce a shutter capable of more completely shutting out light. One aspect is the use of a two-step overlapping end to provide a complementary fit in order to shut out light. Another aspect is the use of an angled engagement pin which engages the louver not at its edge, but into its main expanse and nearer the center of pivot of each louver. Another aspect is the use of an accommodation space to accommodate the “U” shaped attachment member of the simultaneous actuation handle, which accommodation space can vary in size and depth to accommodate structures extending from the simultaneous actuation handle. Regardless of relative size, the louvers, engagement pins, and simultaneous actuation handle can be disciplined to form a neater appearance on the shutter assembly.

Each end recess has a plurality of indentations formed at a predetermined location in a curved clamping inner face thereof for receiving the rib of a respective connector rod captive therein by clamping pressure of the connecting arms about the connector rod to angulate the louvers at a desired angle.
