Removable vane cover fastened to a conventional vertical blind system

Abstract

A vertical blind system includes a conventional vertical blind mechanism, a plurality of Elongated vertical blind vanes preferably of opaque or semi opaque rigid material such as Plastic, aluminum or stiff fabric, pivotally mounted to the vertical blind mechanism; a continuous blind vane cover sheet selected from the group consisting of translucent, or transparent material such as sheer or lace fabric. The cover sheet forms a U-shaped folds that extends between the adjacent blind vanes and removably are secured to the blind vanes at a predetermined spaced intervals by material fasteners. The materials fasteners are constructed and arranged to allow the cover sheet to be detached and reattached to the blind vanes for washing and cleaning, or changing by new. The cover sheet could be secured to a plurality of rigid slats oriented horizontally, thus requiring the use of a different operating system such as a conventional horizontal blind slat mechanism.
