  • Patent number: 6655091
    Abstract: A shutter assembly replaces one or more of the conventional fixed rails with one or more attaching louvers that fixedly attach the attaching louver to the left and right stiles, completing the framing function of the replaced rail(s). A hanger bolt is attached to the attaching louver end and extends through a spacing washer and stile holes for a locknut and washer to complete the attachment. The non-attaching louvers have louver pin assemblies with a nail for driving into the louver, a spacer flange, and an expandable bushing post with a central recess. A finned bushing encompasses the bushing post and a tensioning nail is driven into the bushing post recess to expand the bushing post causing the bushing to bear on the sides of a stile recess sized to receive the bushing. This frictional relationship maintains the position of the louvers when rotated by the tilt rod.
