The present invention relates to window coverings, and more specifically to vertical window shades that do not utilize louvers and/or vanes to control light transmission.
There are many different types of window coverings and treatments for use in all types of settings. The particular aim of these different window coverings may vary depending upon the setting or the desires of the individual persons dressing their windows. For example, commercial settings that include rather larger windows may require an easy to use window covering for shading light during the more sun intensive periods of the day. Typically, large Venetian blinds or large vertical blinds are utilized in this situation. However, other settings, such as residential homes, having ornate decoration schemes, may require coverings suited to the particular decor of the home. Window coverings including soft and supple fabrics are often employed in this latter situation.
One type of window covering often used in more decorative settings is a curtain assembly. Generally, these types of window coverings include at least two curtain panels constructed of either a translucent or a substantially opaque fabric material coupled to a curtain rod. When closed, the panels may substantially cover the window opening, and when open, the panels are typically disposed on either side of the window. The open position typically allows for both full visibility through the window and full entry of light from the outside. Thus, there is typically no light filtering stage whereby the curtains may be situated to allow at least some light to enter through the covering, while at least partially blocking out visibility. Such an intermediate stage has typically hereto for only been provided by less aesthetically pleasing window coverings. Further, the installation of such curtain assemblies generally requires the mounting of a suitable curtain rod and the fixing of curtain panels thereto, and, the opening and closing of such a design often requires that each curtain panel be moved individually. Thus, there are significant drawbacks related to such designs.
Due to the above drawbacks, less aesthetically pleasing window coverings, such as standard Venetian blind assemblies, are widely utilized to provide total covering or uncovering of windows, as well as the above discussed intermediate stages of covering. For example, certain Venetian blind assemblies, as well as similar vertical blind assemblies, are known that include the use of sheer material in addition to the standard rigid vanes typically present in such coverings. Typically, this sheer material is attached to at least two rigid vanes or slats. This type of design allows for the coverings to completely cover and completely uncover a window, as well as provide a light filtering position that substantially reduces visibility through the window while allowing for light to enter. However, as of yet, the prior art designs have only been limited to designs that include rigid vanes or the like, thereby decreasing the overall aesthetic design of the window covering.
Therefore, there exists a need for a window covering assembly that allows for the versatility in the selective covering of windows, and provides a highly aesthetically pleasing design.
SUMMARY OF THE INVENTIONA first aspect of the present invention is a window covering for selectively covering and uncovering a window. The window covering preferably includes a headrail and a unitary sheet of material suspended vertically from the headrail. The unitary sheet preferably is configured so as to define at least two soft vane sections and at least one portion therebetween. The soft vane sections are preferably rotatable between a first position substantially parallel to the window, and a second position substantially perpendicular to the window. The portion is preferably substantially curved when the soft vane sections are in the second position.
Another embodiment of the present invention is another window covering. The window covering according to this embodiment includes a headrail and a unitary sheet of material suspended vertically from the headrail. The unitary sheet is preferably configured to define at least two soft vane sections and at least one non-rigid portion therebetween. The soft vane sections are preferably capable of traversing or translational movement between a closed position where the window is substantially covered by the unitary sheet and an open position where the window is substantially uncovered by the unitary sheet. The soft vane sections are also preferably capable of rotational movement between a first position where the covering at least partially blocks both visibility and light conducted through the window and a second position where the covering at least partially blocks visibility through the window and at least partially allows for light to be conducted therethrough. The window covering, according to this embodiment, preferably does not include a rigid vane.
Another embodiment of the present invention is yet another window covering. The window covering according to this embodiment of the present invention includes a headrail and a plurality of unitary sheets of material suspended vertically from the headrail. Each of the unitary sheets are preferably configured to define at least two soft vane sections and a portion therebetween. The soft vane sections are preferably rotatable between a first position substantially parallel to the window, and a second position substantially perpendicular to the window. The portions are preferably substantially curved when the soft vane sections are in the second position.
BRIEF DESCRIPTION OF THE DRAWINGSA more complete appreciation of the subject matter of the present invention and the various advantages thereof can be realized by reference to the following detailed description in which reference is made to the accompanying drawings in which:
In describing the preferred embodiments of the subject matter illustrated and to be described with respect to the drawings, specific terminology will be used for the sake of clarity. However, the invention is not intended to be limited to any specific terms used herein, and it is to be understood that each specific term includes all technical equivalents which operate in a similar manner to accomplish a similar purpose.
Referring to the drawings, wherein like reference numerals refer to like elements, there is shown in
Headrail portion 12 may be any headrail known in the art that is capable of providing for both traversing and rotational motion to portions of sheet material portion 14 of the vertical shade. Prior art headrails are well known for achieving such operation. For example, suitable headrails are disclosed in U.S. Pat. Nos. 4,214,622, 4,316,493, 5,894,877, 6,755,230 and 6,786,269, the disclosures of which are hereby incorporated by reference herein. Nevertheless, a simplified preferred headrail 12 is shown in
Sheet material portion 14, in accordance with a first preferred embodiment, is more particularly shown in
It is contemplated that the construction of sheet of material 30 may include, among other designs, providing a continuous sheet of opaque material and thereafter removing stitches or the like to provide sheer sections. Thus, the sheer sections would preferably have a lower thread count than the opaque sections. Alternatively, it is also contemplated to provide individual opaque and sheer sections that are bonded together to form a continuous sheet 30. Yet another mode of manufacturing a suitable sheet of material 30 includes weaving a fabric with alternating shear and opaque sections. In this method, sections of the continuous sheet may be weaved to include a higher thread count and thus be more opaque, while sections in between may be weaved to include a lower thread count and thus be more sheer.
A fully constructed sheet portion 14 is shown in
In a similar fashion, weight 50 is retained in the bottom pocket 46. In a preferred embodiment, like that of hem bar 48, weight 50 is preferably of a rectangular shape and is preferably constructed of a relatively dense or heavy material, so as to cause each opaque section 32 to extend in a straight fashion from headrail 12. This provides a uniform length across portion 14, which is aesthetically pleasing and desirable. It is noted that depending upon the type of material utilized in portion 14, heavier or lighter weights 50 may be usable. Further, it is also contemplated that the present invention may utilize specific configurations that do not require such weights. For example, it is contemplated to provide a sheet material portion 14 constructed of a material that would not require a weight or the like to be placed in a bottom pocket 46, in order to force such a straight extension. Additionally, it is also contemplated to insert a substantially rigid vane between pockets 44 and 46 created in opaque section 32. In this type of design, a first end of a rigid vane would be inserted into pocket 44 and a second opposite end would be inserted into pocket 46. The rigid vane would extend along the length of opaque section 32, and may provide further light blocking capabilities, as well as provide further rigidity to sheet 30.
As mentioned above, window covering 10 is useful in selectively covering and uncovering a window.
Finally,
In addition to the above, other embodiments of the present invention are envisioned. For example, instead of providing a sheet material portion 14 (as shown in
Yet another embodiment of the present invention is shown in
In certain embodiments, adjacent opaque sections 132 may be ultrasonically welded or the like, as described above in the first embodiment. For example, similar L-shaped welds may be provided between adjacent opaque sections to create a top pocket and a bottom pocket, like that described above. Such pockets may similarly be utilized to capture a hem bar, weight or the like. Nonetheless, each sheet 130 would preferably remain unconnected along a substantial portion of its length. It is also envisioned to only ultrasonically weld either a top or bottom portion of adjacent opaque sections 132. Similarly, it is clearly envisioned to allow each sheet 130 to remain unconnected to an adjacent sheet. Further, it is also contemplated that in this embodiment, a full length rigid vane (not shown) may be introduced between adjacent opaque sections 132, such that a first end of the vane extends into the top pocket and a second end of the vane extends into the bottom pocket. These vanes may provide further light or visibility blocking capabilities. In addition, as discussed above, it is similarly contemplated to provide sheets 130 that are comprised of a single material, without individual opaque and sheer sections.
All of the above discussed embodiments of the present invention offer the consumer a highly aesthetically pleasing design with the ease and variation of operation of a standard window covering assembly. Essentially, the present invention provides the user with the benefits of both curtain assemblies and blind assemblies. One such benefit not discussed heretofore is the fact that, in addition to the aforementioned blind assembly-like operation of covering 10, it is also possible to utilize the covering in association with standard drapery hardware hold-backs. These hold-backs are well known in the art, and are typically utilized to pull and hold opposing panels of a curtain assembly or the like to opposing sides of a window frame. In accordance with the present invention, the supple nature of sheet material portion 14 allows for such to be pulled to the side of a window frame and held by a hold-back or the like. In situations where individual sheets 130 are utilized, it is possible to pull certain of the U-shaped sheets to one side while other of the sheets is pulled to the other side. Clearly, this adds versatility to the already versatile design.
The aforementioned quick connection assembly is useful in allowing the easy and fast removability of portion 14 from headrail 12. Among other benefits, the quick connection assembly may allow for the easy cleaning of portion 14, as the portion may be removed and cleaned in a washing machine or the like. Similarly, the removability of portion 14 from headrail 12 may allow for different types of portions 14 to be utilized. For example, different colored portions 14 may be employed depending upon different times of the year or moods of the user. Additionally, different patterns or combinations of sheer and opaque sheets may be changed. Yet still, different embodiment portions 14 may be interchanged, for example, a user may switch between the portion shown in
Although the invention herein has been described with reference to particular embodiments, it is to be understood that these embodiments are merely illustrative of the principles and applications of the present invention. It is therefore to be understood that numerous modifications may be made to the illustrative embodiments and that other arrangements may be devised without departing from the spirit and scope of the present invention as defined by the appended claims.
