Abstract

Claims10
A decorative window curtain assembly featuring angularly adjustable louver slats of drapable material for the achievement of a variety of different decorative and translucency effects, the curtain assembly comprising in combination:
- a series of parallel regularly spaced slats of substantially opaque quality arranged to serve as louvers;
- means for rotatably mounting said opaque slats ao as to admit light therebetween when they are oriented perpendicularly to the general plane of the curtain assembly and to progressively shut out the light, as they are re-oriented at a decreasing angle to said plane;
- and
- a series of linking slats of substantially translucent quality occupying the spaces between said opaque slats, without substantially affecting the light-controlling action of the latter;
- the translucent slats being longitudinally connected to the opaque slats, so as to form a continuous assembly of alternatingly opaque and translucent slats in the direction transverse to the extent of the slats;
- and wherein
- said continuous assembly of alternatingly opaque and translucent slats is constituted by a continuous web of said drapable material extending in said transverse direction, whereby single-layer web sections alternate with double-layer, tubular web sections of at least equal web length, the former serving as said translucent linking slats, while the latter, transversely flattened so as to leave a minimum interval in the web direction between successive single-layer sections, serve as said opaque slats;
- and
- the opaque slats further include slat shaping means holding their constituent double-layer web sections in the aforementioned transversely flattened shape and giving them the character and appearance of louver slats, by stiffening at least their edge portions, thereby creating an H-shaped cross-sectional curtain configuration, two adjacent opaque slats forming the two legs of the H-shape, and the intermediate linking translucent slat forming its cross bar.
