Claim 1
Independent Claim
291 words
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.

Claim 3
Dependent Claim
28 words
A curtain assembly as defined in claim 1, wherein the slat shaping means includes a flat rectangular frame inserted between the two web layers of each opaque slat.
Claim 4
Dependent Claim
16 words
A curtain assembly as defined in claim 2, wherein said frame is a rectangular wire frame.
Claim 5
Dependent Claim
30 words
A curtain assembly as defined in claim 1, wherein the slat shaping means is a stiffening component which is permanently united with the two web layers of each opaque slat.
Claim 6
Dependent Claim
32 words
A curtain assembly as defined in claim 1, wherein the slat shaping means is a thin strip or batten of plastic material inserted between the two web layers of each opaque slat.
Claim 7
Dependent Claim
62 words
A curtain assembly as defined in claim 1, wherein the slats extend vertically; and said means for rotatably mounting the opaque slats includes: a stationary curtain rail extending above the curtain and having a downwardly facing longitudinal slot, and a sliding head at the upper extremity of each opaque slat riding in said curtain rail in a vertically guided, rotatable engagement therewith.
Claim 8
Dependent Claim
16 words
A curtain assembly as defined in claim 1, wherein said drapable material is a woven fabric.
Claim 9
Dependent Claim
28 words

Claim 10
Dependent Claim
21 words
