Title: COMBINATION WINDOW OR DOOR COVERING
FIELD OF THE INVENTION
[0001] This invention relates to window and door coverings. In particular, the invention relates to combination of a venetian blind and a flexible shade.
BACKGROUND OF THE INVENTION
Title: COMBINATION WINDOW OR DOOR COVERING
FIELD OF THE INVENTION
[0001] This invention relates to window and door coverings. In particular, the invention relates to combination of a venetian blind and a flexible shade.
BACKGROUND OF THE INVENTION
[0002] Venetian blinds are well known. Such blinds consist of a plurality of horizontal parallel slats supported on cord or tape ladders which are suspended from a header rail mounted to the top of the window or door.
A bottom rail is connected to the bottom ends of the ladders. A tilt control mechanism is typically provided in the header rail to tilt the slats to control the amount of light entering the room. Lift cords typically run from the bottom slat to a cord lock located in the header rail. The lift control mechanism permits the lifting or lowering of the bottom rail to control the portion of the window covered by the blind.
A bottom rail is connected to the bottom ends of the ladders. A tilt control mechanism is typically provided in the header rail to tilt the slats to control the amount of light entering the room. Lift cords typically run from the bottom slat to a cord lock located in the header rail. The lift control mechanism permits the lifting or lowering of the bottom rail to control the portion of the window covered by the blind.
[0003] One of the disadvantages encountered with prior art venetian blinds is that, when a user tilts the slats to permit light to enter the room, privacy is compromised. Specifically, when the slats are in a position where light is permitted to enter the room, a person standing outside the window or door may be able to see into the room through the openings between the slats.
[0004] To address this disadvantage, a number of combination window coverings have been developed. These combination window coverings add a translucent flexible sheet or shade to the venetian blind. The translucent shade permits light to pass into the room when the slats are open, but obscures visibility of the room interior.
[0005] The prior art combination window coverings have a number of disadvantages. One of the disadvantages of some of the prior art combination window coverings is that separate controls are required to control the venetian blind and the shade, making such combination window coverings more difficult and time-consuming to operate. Other prior art combination window coverings provide a single control for raising the venetian blind and the shade, but have other disadvantages. Specifically, the single controls are complex and expensive, requiring significant modifications to the venetian blind. In addition, when the shade is raised along with the venetian blind, it does not fold up in an esthetically pleasing manner. Esthetic qualities of window coverings are an extremely important feature for consumers.
[0006] Accordingly, there is a need for an improved combination window covering which is esthetically pleasing, is simple to operate, is less expensive, and can be manufactured from existing commercially available materials used for conventional venetian blinds.
SUMMARY OF THE INVENTION
SUMMARY OF THE INVENTION
[0007] The embodiments of the invention described herein provide a window or door covering which is a combination of a venetian blind and a shade. In accordance with a preferred embodiment, the window or door covering is a combination of a venetian blind and a roman blind, where both the venetian blind and roman blind can be raised or lowered together using a single control, such as a lift cord or cords.
[0008] According to a first aspect of the invention, a combination window or door covering is provided. The window or door covering comprises:
a) a header rail;
b) at least one flexible ladder suspended from the header rail, the at least one ladder comprising a plurality of rungs;

[0011] Figures 1 and 2 show a combination window or door covering 10 according to a preferred embodiment of the present invention. The combination window or door covering 10 comprises a venetian blind portion 12 connected to a flexible planar shade 14, as described in detail below.
1 .1 1 4 - .wYb .. .dd.a+ix... ..i.....
Preferably, the shade 14 is composed of a translucent material to permit light to pass through, but to obstruct visibility. The shade 14 is preferably positioned adjacent the interior face of the venetian blind portion 12.
However, it will be understood by those skilled in the art, the shade 14 may be positioned on the exterior face of the venetian blind portion 12.
Alternatively, two shades 14 (not shown) may be provided adjacent to each face of the blind portion 12. A used herein, "exterior" refers the face of the blind which faces the window or door, and "interior" refers to tfie face which faces the room interior.
[0012] The venetian blind portion 12 and shade 14 are suspended from a header rail 16. Preferably, the venetian blind portion 12 is suspended from exterior header rail portion 16a and the shade 14 is suspended from interior header rail portion 16b.
1 .1 1 4 - .wYb .. .dd.a+ix... ..i.....
Preferably, the shade 14 is composed of a translucent material to permit light to pass through, but to obstruct visibility. The shade 14 is preferably positioned adjacent the interior face of the venetian blind portion 12.
However, it will be understood by those skilled in the art, the shade 14 may be positioned on the exterior face of the venetian blind portion 12.
Alternatively, two shades 14 (not shown) may be provided adjacent to each face of the blind portion 12. A used herein, "exterior" refers the face of the blind which faces the window or door, and "interior" refers to tfie face which faces the room interior.
[0012] The venetian blind portion 12 and shade 14 are suspended from a header rail 16. Preferably, the venetian blind portion 12 is suspended from exterior header rail portion 16a and the shade 14 is suspended from interior header rail portion 16b.
[0013] Referring now to Figures 1, 2, 4A, and 4B, interior header rail portion 16b is secured to exterior portion 16a by any suitable means, such as by fastener 18. A conventional tilt mechanism 20 is mounted in the exterior header rail portion 16a. The tilt mechanism 20 includes two cam members 22a, 22b mounted on a tilt rod 24 received longitudinally in the exterior header rail portion 16a. A tilt control cord 26 is connected to the tilt mechanism 20 by conventional means. It will be understood by those skilled in the art that a wand (not shown) may be used instead of the tilt control cord 26.
[0014] Referring again to Figure 1, a first ladder 30a and a second ladder 30b are suspended from cam members 22a and 22b, respectively. It will be understood by those skilled in the art that any suitable numbers of ladders and cam members may be provided depending on the size of the blind required. A plurality of slats 32 are supported by the ladders 30a, 30b.
The slats may be any suitable width (such as 1" or 2" slats), shape (such as rectangular cross-section or "airplane wing" cross-section), or material (such as plastic, wood, aluminum, or the like).
The slats may be any suitable width (such as 1" or 2" slats), shape (such as rectangular cross-section or "airplane wing" cross-section), or material (such as plastic, wood, aluminum, or the like).
[0015] Referring now to Figures 3 and 4A, the slats 32 rest on corresponding rungs 34 of each ladder 30a, 30b.
. 116 a.IdH 04~ . . 1, 1 1 [0016] Referring again to Figure 1, each slat 34 may include a pair of slots 36a, 36b. Each slat 32 may also include two pairs of opposed notches (not shown) to engage the vertical cords of the ladders 30a, 30b.
. 116 a.IdH 04~ . . 1, 1 1 [0016] Referring again to Figure 1, each slat 34 may include a pair of slots 36a, 36b. Each slat 32 may also include two pairs of opposed notches (not shown) to engage the vertical cords of the ladders 30a, 30b.
[0017] First and second lift cords 38a, 38b may be secured to a heavier bottom slat 40 and run through the slots 36a, 36b of each slat 34. The lift cords pass into the interior header rail portion 16b through openings (not shown). The lift cords 38a, 38b pass through a conventional cord lock 44 and exit the header rail portion through a second opening (not shown), where they are preferably connected together at lift control 42.
[0018] It will.be understood by those skilled in the art that any suitable number of lift cords may be provided depending on the size of the combination window or door covering 10. In addition, those skilled in the art will understand that slots 36a, 36b are not essential. If the slots are not present, the lift cords may run vertically proximate to either the front or rear vertical cord of the ladders 30a, 30b. In such case the lift cords may be secured by loops in the vertical cord of the ladders.
[0019] Referring now to Figures 1, 3, and 5 the shade 14 includes five substantially horizontal fold lines, although those skilled in the art will understand the that the shade 14 may have any number of fold lines depending on the side of the window or door to which it is fitted. In one embodiment, the fold lines are conventional plastic splines 60a-e which are secured to the exterior face 61 of the shade 14 by threading a portion of the shade where a fold line is desired onto each spline. Each spline 60a-e includes a rail 62 along its longitudinal edge. Preferably, two plastic clips (only one is shown in Fig. 5) are secured to each spline 60a-e by sliding each clip 64 onto the rail 62 and positioning each clip 64 proximate to the ladders (only connection to ladder 30a is shown in Fig. 5). End caps 66 (only one is shown in Fig. 5) are then fitted over the spline to secure the shade 14 and clips 64. Each clip includes a ring 68. An S-shaped connector 70 engages the ring 68 at one end, and preferably a vertical cord 72 on an adjacent . .......,n...,4 ,.s.W1. . ..,y.y,y.yil..,..w.ek..... .. .

ladder 30a at the other end in order to secure each spline 60a-e of the shade 14 to the ladders 30a, 30b of the blind portion 12.
[0020] The operation of the first embodiment will now be described with reference to Figures 1, 4B, and 5. The tilting of the slats 32 in the venetian blind portion 12 is controlled in a conventional manner by tilt cord 26 and will not be further described. When the slats 32 are in an open position (shown in Fig. 1), the combination window or door covering 10 permits light to enter the room, while affording privacy by virtue of the shade 14 obscuring visibility.
[0021] The vertical movement of the combination window or door covering 10 is controlled by pulling and releasing the lift cords 38a,b with control 42. For example, in order to lift the combination window or door covering 10 from the fully extended position shown in Figure 1 into the raised position shown in Figure 4B, the user pulls on the lift cords 38a,b. The pulling action causes the cord lock 44 to release and the venetian blind portion 12 to be raised. Initially, the vertical cord 72 simply slides through the S-shaped connector 70. As soon as the S-shaped connector 70 of each spline 60a-e abuts against adjacent rung 34x, the shade 14 is raised together with venetian blind portion 12.
[0022] As best shown in Figure 4B, the connection of the shade 14 to venetian blind portion 12 only at splines 60a-e causes pleats 80a-c to form in the shade 14. Each pleat is located partially behind the immediately adjacent higher pleat to give the shade 14 an aesthetically pleasing appearance when raised.
[0023] The combination window or door covering 10 is lowered by moving the lift cords 38a,b so that the cord lock 44 is released and the blind portion 12 may be lowered using the force of gravity.
[0024] The combination window or door covering according to the present invention provides the advantage of manufacturing an improved product using inexpensive standard off-the-shelf parts (i.e. standard cord ladders, and plastic or cord connectors) used for conventional venetian and roman blinds, thereby reducing the cost and simplifying the manufacture of the combination window or door covering.
[0025] Figure 6 shows a second embodiment of a window or door covering 100 where like parts have been assigned like reference numbers and will not be further described.
[0026] Referring to Figure 6, the fold lines of shade 14 are formed by an envelope 102 in the interior face of the shade 14. A rod 104 made of wood, plastic, or the like is located in the envelope 102. A ring connector is preferably sewn to a seam 108 in the shade 14. The vertical cord 72 of adjacent ladder 30a passes through the ring connector 106 in order to secure the shade 14 to the ladder 30a. This embodiment operates in the same manner as described for the first embodiment above.
[0027] While the present invention as herein shown and described in detail is fully capable of attaining the above-described objects of the invention, it is to be understood that it is the presently preferred embodiment of the present invention and thus, is representative of the subject matter which is broadly contemplated by the present invention, that the scope of the present invention fully encompasses other embodiments which may become obvious to those skilled in the art, and that the scope of the present invention is accordingly to be limited by nothing other than the appended claims, in which reference to an element in the singular is not intended to mean "one and only one" unless explicitly so stated, but rather "one or more." All structural and functional equivalents to the elements of the above-described preferred embodiment that are known or later come to be known to those of ordinary skill in the art are expressly incorporated herein by reference and are intended to be encompassed by the present claims. Moreover, it is not necessary for a device or method to address each and every problem sought to be solved by the present invention, for it to be encompassed by the present claims.
