Abstract: A shutter-blind system for windows is provided. The system includes a plurality of rotatable parallel louvers. Each louver is rotatable about an axis offset from its center of gravity. The system further includes a resisting member coupled to a louver located at a lower end of the plurality of louvers, the center of gravity of the louvers with the offset axis pulling against the resisting member to maintain tension in the collapsible linkages. All of the louvers of the plurality of louvers are rotated in a substantially matched rotation in response to rotation of the lower louver. All of the louvers are held in position in response to the force of gravity on the offset louvers acting against the resisting member.

Abstract: A shutter-blind system for windows is provided. The system includes a frame and a plurality of rotatable parallel louvers coupled within the frame. Each louver of the plurality of louvers is operatively coupled to adjacent louvers with a collapsible linkage. The system may further comprise a biasing member coupled to a first louver located at a first end of the plurality of louvers and a resisting member coupled to a second louver located at a second end of the plurality of louvers. The biasing member pulls against the resisting member to maintain tension in the collapsible linkage. According to certain embodiments, the frame elements are coupled within a window opening and trim elements are coupled to cover gaps between the frame elements and the window opening.

Abstract: In a window treatment having vertical blind elements individually suspended from associated hanger elements, each of the vertical blind elements being connected by a connecting panel, an improved hanger is disclosed. The improved hanger includes a hanger body and a bonding portion located near a lower portion of the hanger body. The bonding portion is configured to receive the vertical blind element. Also included is an aperture for hanging the window treatment, the aperture being located near an upper portion of the hanger body, the aperture being spaced at a position substantially at a center of gravity of the vertical blind element with the connecting panel.
