  • Patent number: 6219970
    Abstract: A frame member having a centrally disposed opening, a plurality of louvers pivotally disposed within the opening of the frame member, a relief notch on the lateral edge of the louver, and a louver adjusting member attached to the plurality of louvers. The louver adjusting member is completely disposed within the relief notch of the louvers, thereby maintaining at least a flush profile on either the inner surface or outer surface of the window shutter when the louvers are in the closed position. The window shutter apparatus further comprises a hanging strip that includes pivotally attaching the frame member thereto, a compliance strip for attachment to the hanging strip, and a T-strip attached to either the hanging strip or frame member. The compliance strip adjusts for dimensional variations in the side surfaces of the window opening that leave a gap when the hanging strip is placed adjacent thereto.

  • Patent number: 6206074
    Abstract: An adjustable finial mounting bracket apparatus generally comprising a first bracket, a firs t flange, a second bracket, a second flange, a knob, and a screw. The first flange and second flange extend outwardly from the first bracket and the second bracket, respectively, and are adapted to engage the lips of a headrail for a curtain or drapery. The first bracket and the second bracket abut each other and are attached together by a screw. Each bracket is adapted to longitudinally move with respect to the other, thereby providing the adjustment capability for attachment onto headrails of varying sizes. The surfaces of both the first bracket and the second bracket are corrugated so that detent movement is provided when sliding first bracket relative to second bracket, and greater holding strength of the apparatus on the headrail is achieved when the screw is tightened.
