Abstract

Abstract A flexible closure panel adapted, for example, to close a rectangular opening in a wall, and capable of being rolled upon an elongated cylinder supported adjacent to and parallel with the upper edge of the rectangular opening. Drive means are attached to the cylinder for effecting rotation of said cylinder in either rotational direction and weight means is attached to the lower edge of said panel. Plural rollers are disposed below said cylinder and are capable of supporting same adjacent said upper edge of said opening. Plural, coaxial and spaced idler rolls are supported upon said wall adjacent to, spaced from and directly above said cylinder. Plural flexible bands, each one being connected at its opposite ends to and between said weight means and said cylinder, extend up and over said rolls and, being under tension, operatively support the panel and weight means.
