Abstract: A vertical blind panel including a plurality of substantially opaque louvers and a plurality of sheer transparent or translucent spacers. Each of the plurality of spacers is disposed between a respective pair of the plurality of louvers. At least one of the plurality of louvers includes a first vertically oriented louver portion connected to a second vertically oriented louver portion.

Abstract: A frangible connection for connecting parts of a knitted textile into a single panel is disclosed. The frangible connection is formed of a yarn having a lower tensile strength than that used to knit the parts of the panel so that the parts can be readily disconnected by tearing the frangible connection without damaging the structure of the parts themselves. Thus, a plurality of vertical blind louvers may be knitted into a single panel on a single knitting machine and separated later, preferably prior to installation. Knitted patterns which extend across multiple louvers may thus be practically manufactured without the difficulties in alignment which might be present if each louver were manufactured separately. The frangible connection also functions as a hinge for pivotably connecting the louvers of a combination blind together.

Abstract: The present invention is directed to window treatments such as vertical blinds manufactured from a knitted textile material. Each of a plurality of louvers is knitted into a single panel and attached together by a frangible hinge which permits the louvers to pivot relative to each other, or may be torn to separate the louvers from each other without damage to the louvers. In installations requiring multiple panels to be attached together, a terminus may be provided to permit attachment of one panel directly to the other. Alternately, a connection strip may be employed between two panels. In the event that the knitted textile louvers are not sufficiently opaque, auxiliary louvers may be provided and attached in alignment over the louvers.

Abstract: A vertical blind assembly including at least one vertical blind panel, the at least one vertical blind panel including a plurality of partially opaque louvers, and a plurality of sheer transparent or translucent spacers. Each of the plurality of spacers is disposed between a respective pair of the plurality of partially opaque louvers. A substantially opaque auxiliary louver is disposed behind each one of the plurality of partially opaque louvers. A frangible hinge is disposed between each partially opaque louver and an adjacent spacer. A louver hook is attached to a top edge portion of each partially opaque louver, wherein each louver hook hooks over a top edge of a corresponding auxiliary louver.
