Abstract: A window insert suitable for insertion into a conventional window insert receptacle includes a frame and a blind assembly mounted to the frame. The frame defines an opening, and is adapted for insertion into the window insert receptacle. The blind assembly can include a plurality of slats which cover the opening.

Abstract: A shutter adapted to be attached in hinged relation to a frame defining an opening, whereby at least part of the opening may be covered by the shutter, includes a shutter body. The shutter body has opposed top and bottom and opposed side body members, the body members defining a shutter opening. A plurality of movable slats extend horizontally across the shutter opening. The slats are individually suspended and vertically spaced from each other by at least two flexible ladder suspension harnesses. Each harness has two parallel vertical strands with each slat held in fixed relation to a selected location on each of the vertical strands. Lateral movement of the slats is limited by the vertical strands and longitudinal movement of the slats is limited by the side body members. Means are provided to selectively lower and raise at least one of the vertical strands of each harness to rotate the slats about their longitudinal axes.

Abstract: A supplemental window and blind unit (10) adapted to be installed in a conventional window (13, 15) having a conventional frame (11) and an original window pane (26). A supplemental frame (28) is attached to the conventional frame (11), and a sash (36) is attached to the supplemental frame (28) in hinged relation. A supplemental window pane (34) is mounted in the sash (36) to close the framed window opening (29) defined by the supplemental frame (28). A window blind (46) is attached to a selected part of the sash (36) so that the window blind (46) is between the supplemental window pane (34) and the original window pane (26) when the sash (36) is in its closed position, whereby the conventional window (13, 15) may be modified to be a window having multiple panes with a window blind enclosed between two of the panes.
