Abstract
A curtain for horizontal venetian blinds comprising a conventional and known type of a horizontal venetian blind, to which is removably attached a curtain. The curtain can be made of translucent material.
Description
Title: Curtain for horizontal Venetian blinds.
Background of the in~rention Field of the invention.
This invention relates to venetian blinds and especially to a curtain for venetian blinds.
Horizontal venetian blinds are well known in the art. They are used to be drawn up or let down to cover an opening, such as a window or a door.
Typically, a horizontal venetian blind includes a headrail, a bottomrail and a plurality of parallel slats. The latter are attached by at 1 Q least two sets of flexible support ladder tapes to the head and bottom-rails. A system is used for changing the position of the plurality of parallel slats and for raising and lowering the blind.
Attempts have been made to enhance the enjoyment of using venetian blinds.
Several United States patents have addressed this issue. Far example, United States Patent No. 2,646,114, dated July 21, 1953 and granted to Kearny for a "Venetian Shade" discloses an arrangement, wherein the window shade assembley constitutes the upper portion of the arrangement, while the venetian blind assembley, i the lower portion thereof. The upper portion consists of a sheet of pliable material which is wound upon a conventional fiorm ofi spring roller. The lower portion of the window shade is provided with cylindrical elements which depend therefrom and constitute bearings for supporting the headrail of the venetian blind assembley. Curing the use of the venetian shade, the following relative positions of operation can occur ;; the window opening covered by the window shade at the top half and the venetian blind assembly at the bottom half thereof; the window shade portion of the device is rolled up so that the venetian blind assembly covers the upper half of the window opening, and the venetian blind assembly is in its fully collapsed position and the window shade rolled down to fully cover the window opening.
The arrangement of the venetian blind assembley and the window shade assembly may be reversed, with the venetian blind assembly disposed at the upper part of the device, and the window shade assembly disposed at the bottom thereof.
The window shade assembly described above has two shortcomings. First, by combining in continuation a window shade of the spring roller type with a venetian blind , a complicated structure occurs. This structure requires special parts, such as cylindrical

United States Patent No. 5,1 ~1,~53, dated June 16,1992 and granted to Niisson for a "Window covering apparatus" discloses a venetian blind having a headrai! for attachment at the window opening, a plurality of slats and a bottomrail. A flexible lift cord extends from the headrail for raising and lowering the plurality of slats and a first lift cord has a cord extending therethrough for locking the slats. A pleated shade is supported at the top on the venetian blind bottomra!!. A second lift cord is attached from the venetian blind headrail, through the venetian blind slats, and through each of the folds of the foldable pleated shade to the pleated shade bottomrail. A pleated shade lift cord lock is located in the venetian blind headrail and has a cord coupled therethrough so that the second lift cord extends through the venetian blind slats and through each foldable pleat of the pleated shade. Thus, the pleated shade can be raised or lowered on the venetian blind bottomrail by the lift cord from the venetian blind headrail, independently of the venetian blind. The pleated shade has a plurality of elongated folds, each fold or slat having one elongated edge attached ~0 to the next adjacent elongated fold to form a foldable pleated shade.

3 This ~indo~v covering is considered to have tyro disadvantages.
First, use is rr~ade of a su~ip9imentary lifting cord. ~ecor-~d, tP-re struutui~e of the pleated shade is quite complex.
~lnited Mates Patent (~o. 5,~~~,88~, dated August ~3, ~ ~J~. and granted to ~udkins discloses a "i~'enetian type ~indoa~ covering"
discloses a honeycomb v~indow covering structure that operates as a venetian. The structure has two sheets of material. The sheets are spaced apart and orientated so as to be generally parallel to each other. A series of slats connects the first and second sheets of traterial.
14 For connecting each slat to the first and second sheets of material, first and second connecting portions are used. The connecting portions may be tabs formed on pleats of the first and second material, tabs formed on the slats themselves, extending portions extending out to one side only of each sheet of material, a separate structure affixed to 1 ~ the sheets of material, or a flexible adhesive betuveen the slats and the first and second sheets of material.
The first sheet of material and the second sheet of material are made of a material that does not act as a barrier to heat or light. The slats prevent heat and fight fr om passing to and from the front and rear 2t? structure. The disclosed structure departs from the knotnrn venetian blind structure by providing a complicated design without clear benefits.
United States Patent No. 5,419,385, dated May ~0, i 995 and granted to Voge! et al. for a "double sheet light control window covering with unique vanes" describes a window covering of the ty~ wherein a pair of fabric sheets are suspended vertically in a parallel orientation and interconnected at spaced intervals by parade! vanes. The sheets of material are transparent or translucent, while the vanes have some degree of opacity. When the window covering is in a open position, the vanes extend substantially perpendicularly to the sheets of material, such that light is allowed to pass through the window covering, but in a closed position, 'the sheets are shifted such that vanes extend substantially parallel to the sheets to block the passage of light therethrough.
The main disadvantage of the above described window covering resides in the fiact that each vane must be connected to the adjacent sheets.
From the foregoing, it can be appreciated that there is a need to provide an assembly, which achive the advantages of both a curtain and a horizontal venetian blind.
Therefore, it is a principal object of the invention to enhance the use of a typical horiiontal venetian blind, known for its simplicity, reliability, and availability, by a simple combination with a curtain.
It is a further object of the invention to provide a curtain attachable to new or already in use horizontal venetian blinds.
It is a still further object of the invention to use a curtain which can eliminate or diffuse the lighfi and view depending on the type of material used.
It is a still further object of the invention to provide a curtain which is easily removed for cleaning or replacing.

Brief description of the drawings.
The use and advantages of the present invention will become more readily apparent upon reading and following disclosure and reffering to the attached drawings, wherein:
Fig. 1 is a front elevational view of a sheer curtain in combination with a horizontal venetian blind;
Fig. 2 is a sectional view taken along line AA-AA in Fig.1; and Fig. 3 is a sectional view taken along line BB-BB in Fig. 1.
Detailed description of the preferred embodiment Referring now to the drawings, a sheer curtain for horizontal venetian blind 10 is described.
A horizontal venetian blind 12 comprises a headrail 14 and a bottomrail 16. A plurality of parallel slats 18 are suspended from headrail 14, by three sets of flexible support ladder tapes 20, 22, 24.
At least two sets of flexible support ladders are always used. The lower ends of each set of flexible support ladders 20 or 22 or 24 are attached to the bottomrail 16, which provides weight for raising and lowering plurality of parallel slats 18. Each set of flexible support ladders 20 or 22 or 24 includes, at one side of plurality of parallel slats 18, a front cord 26 (towards the room), at the other side of plurality of parallel slats 18- a back cord 28 (towards the window), and a lift cord 30 which passes through an elongated aperture 32, provided in each slat of plurality of parallel slats 18.
A connection between each front cord 26 and each back cord 28 is made, under each slat of plurality of slats 18, by a transverse support cord 34.
Typically, venetian blind 12 is provided with a tilt control arm (not shown) and a lifting cord (not shown). The lifting cord lifts bottom rail 16 lifting each slat of plurality of slats 18 thereagainst, as venetian blind 12 is raised, or spreads plurality of slats 18 apart, as bottomrail 16 is lowered.
A sheer curtain 36 made of transluscent material is used in combination with horizontal venetian blind 12.The width and height of sheer curtain 36 are substantially the same as those of venetian blind 12, when bottomrail 16 is completely lowered. In the present example, the material used for sheer curtain 36 is made of 100 per cent polyester and sold by Aftex under the trade name Canavoile Sheer 118 inches.
Sheer curtain 36 is attached to horizontal venetian blind as follows:
- to headrail 14 and bottomrail 16, use is made of Velcro (trademark) straps 38 which are applied on the whole length of head and bottomrails 14 and 16;
-additionally, proximate to headrail 14 and parallel to it, use is made of an elongated semirigid strap 40 (thin metal or plastic), which by an adhesive, is removably secured to sheer curtain 36, except the portions wherein front cords 26 are contiguous to sheer curtain 36; there, elongated semirigid strap 40 passes behind front cords 26, by overlapping them; the use of elongated semirigid strap 40, eliminates formation of slack in sheer curtain 36, regardless of plurality of slats 18 tilted position;
-groups of attaching tabs 42 between sheer curtain 36 and front cords 26 are provided; each group of attaching tabs 42 is situated on a line, parallel to headrail 14; each attaching tab 42 is constituted by a Velcro (trademark) fastener, having one part attached to sheer curtain 36, while the other part is affixed to it after overlapping front cord 26.
-Tapes 46 extending on the whole length of sheer curtain 36, are located to correspond to the sets of flexible support ladders 20, 22, and 24, respectively, in order to cover the light zones due to elongated apertures 32, which let the light pass even the horizontal venetian blind 12 is lowered and slats of plurality of parallel slat 18 are tilted to complete closing. Furthermore, tapes 46 provide additional rigidity to sheer curtain 36, especially during folding of sheer curtain 36, when horizontal venetian blind 12 is being raised. Tapes 46 are secured on their whole length by a flexible adhesive. In the present embodiment, tapes 46 are made of a material consisting of 70 per cent polyester and 30 per cent cotton, with a foam back for blackout. The material is sold under the name Textralon S (trademark) Blackout.
While the above description constitutes a preferred embodiment of the invention, it is to be understood that the disclosure is merely exemplary of the invention, which may be embodied in various forms.
Therefore, specific structural and functional details herein are not to be interpreted as limiting, but merely as a basis for the claims and as representative basis for teaching one skilled in the art to variously employ' the present invention in virtually any appropriately detailed structure.
