摘要

The awning for a building door or window has a cloth support defining parallel rectilinear alternating opaque and translucent or transparent strips. The latter can be obscured by opaque strips (C) fixed on a support attached to rods (4,5). he rods allow winding and unreeling of the awning to allow selective exposure of the transparent sections.
