Abstract
A window covering including a plurality of panels vertically suspended from a vertical securement member is provided. The plurality of panels is secured with the securement member about an upper longitudinal portion of the panels at spaced intervals along the securement member. The panels are freely suspended or dangle from the securement member such that a lower longitudinal portion of the panels is not connected with the securement member or the opening member. A weighted edge member may be included about the lower longitudinal portion of the panels. The window covering is opened by adjusting the opening member to rearwardly and vertically stack the plurality of panels.
Description
- The present invention relates to the field of window coverings, and more particularly to window coverings including a plurality of panels.
- Decorative window coverings are popular items for providing privacy and blocking light. These window coverings take on various forms, such as Roman shades, Venetian blinds, vertical blinds, honeycomb shades, and the like. Several of these window coverings include a panel or plurality of panels that cover an opening, which are connected to an adjustment mechanism with one or more control members.
- For example, one popular type of window covering is known as a Roman shade. This type of shade consists of a fabric material attached along its top edge to a head rail and is gathered at spaced intervals to provide a series of soft folds across the face of the fabric. Consequently, the typical Roman shade has a cascaded or softly pleated appearance. Such Roman shades are constructed so that when they are raised, they gather from the bottom in generally horizontal folds or pleats until the entire shade resides near the top of the window covering. In some versions, the top of the window covering may also be lowered. The shades are operated by pulling on control members, which are attached to the shade. The control members are usually secured to a bottom portion of the panel with adhesive, ultrasonic welding, sewing, tying or the like.
- An alternative to the conventional Roman shade is disclosed in co-pending application Ser. No. 10/427,829 filed on May 1, 2003, which is incorporated herein by reference. Unlike the standard Roman shade, the Roman style shade disclosed in co-pending application Ser. No. 10/427,829 enables the opening of the individual rows to create gaps in the face of the shade without requiring the entire shade to be raised.
- Another common type of window covering is a Venetian blind. Venetian blinds are typically constructed of a plurality of slats that are supported by a pair of ladders, which are controlled by an adjustment mechanism in a head rail. The ladder typically includes a pair of parallel cords suspended from the head rail and connected to a bottom rail. A number of rungs span across the parallel cords and support the slats. An alternative to the conventional Venetian blind is disclosed in co-pending application Ser. No. 10/413,200, which was issued as U.S. Pat. No. 6,792,996 and is incorporated herein by reference, which utilizes non-ladder control members and has a configuration that allows the slats to conceal the control members and holes for the control cords when the slats are closed.
- While Roman shades and Venetian blinds are aesthetically pleasing, a window covering with a linear or generally flat appearance that maintains its general appearance whether opened, closed or partially opened may be desired in some instances. The present invention provides a suitable window covering.
- The present invention provides a novel and improved window covering. The window covering includes a head rail that has a control mechanism, such as a cord lock, adapted to control raising and lowering of an opening member suspended from the head rail. A securement member, such as a cord, is also suspended from the head rail. A plurality of panels is secured with the securement member about an upper longitudinal portion of the panels. Each of the panels is secured with the securement member at substantially evenly spaced intervals. The panels are freely suspended such that a lower longitudinal portion of the panels is not connected with the securement member or the opening member so the panels hang vertically from the securement member. A weighted edge member may be included about the lower longitudinal portion of the panels.
- Preferably, the plurality of panels are in an overlapping relationship with one another. In particular, the lower longitudinal portion of a panel overlaps with the upper longitudinal portion of the lower adjacent panel. As such, when the window covering is closed, there are no gaps between panels that would permit light to enter a room. Similarly, the opening and securement members are concealed by the overlapping panels when the window covering is in the closed position.
- The lowermost panel of the plurality of panels is also secured with the opening member about an upper longitudinal portion. The other panels position between the headrail and the lowermost panel are unconnected to the opening member. In other words, adjustment of the opening member only directly moves the lowermost panel. In some embodiments, additional opening members may be included and secured to a different panel. One example of such a configuration is discussed in further detail below.
- To open the window covering, a user pulls or retracts the opening member, which draws upwards the lowermost panel while the remaining panels remain in a resting position. The lowermost panel slides upwards substantially parallel to and behind an upper adjacent panel. By continuing to retract the opening member, the upper longitudinal portion of the lowermost panel contacts the upper longitudinal portion of the upper adjacent panel. The lowermost panel is therefore no longer able to move in an upwards direction independent of the upper adjacent panel. As such, the lowermost panel and the upper adjacent panel are moved together behind the next upper adjacent panel. Each of the panels are rearwardly stacked in this manner as the opening member is retracted.
- By rearwardly stacking the panels in this manner, the vertical and straight profile of individual panels is maintained as the window covering is opened. Accordingly, the aesthetic appearance of the window covering is largely kept constant whether the window covering is in a fully closed, partially opened or fully opened position.
- An alternative embodiment of the present invention affords the capability of lowering the various panels as a different manner of opening the window covering. The window covering, as in the previous embodiment, includes rows of panels. A valance panel is secured directly to the head rail. A plurality of additional panels are suspended by control members from the head rail. The upper longitudinal portion of an uppermost panel is secured with a first opening member such that the uppermost panel is operatively connected to the head rail. A securement member is also secured with the upper longitudinal portion of the uppermost panel, and is also secured with the upper longitudinal portion of the other panels, except the valance panel. The securement member is not connected with the head rail.
- A lowermost panel of the plurality of panels is also secured with a second opening member about an upper longitudinal portion thereof. The second opening member is suspended from the head rail and is controllably adjusted with a control mechanism. The other panels are not secured with the second opening member.
- To open the window covering, a user may pull or retract the second opening member, which draws upwards the lowermost panel while the remaining panels remain in a resting position in the manner previously described. The window covering may also be opened by lowering the uppermost panel by lowering the first opening member. In either event, the position lowermost panel relative to the upper adjacent panels is adjusted such that the lowermost panel is positioned behind and substantially parallel with the upper adjacent panel.
- For example, when raising the second opening member, the lowermost panel slides upwards substantially parallel to and behind an upper adjacent panel. By continuing to retract the opening member, the upper longitudinal portion of the lowermost panel contacts the upper longitudinal portion of the upper adjacent panel. The lowermost panel is therefore no longer able to move upwardly independent of the upper adjacent panel. As such, the lowermost panel and the upper adjacent panel are moved together behind the next upper adjacent panel. The panels are rearwardly stacked in this manner as the opening member is retracted. By contrast, as the first opening member is lowered, the plurality of panels above the lowermost panel slide down such that the upper adjacent panel to the lowermost panel slides in front of and substantially parallel to the lowermost panel. Because the panels overlap, subsequent panels are stacked in front of previously stacked panels. The first and second opening members may operated in any combination. For example, if the second opening member lowers all the panels into a stack, the first opening member can raise the entire stack.
- One preferred feature of the window covering of the present invention includes the manner in which the panels are secured with the securement member and opening member. Each of the panels may be secured with the securement member and opening member with fastener modules. In one embodiment, the fastener module includes a clip member securable to the upper longitudinal portion of a panel and a buckle member comprising a housing and an engagement member, the buckle member suitable for detachable and selectable securement to the securement member. In a preferred embodiment, the securement member is a cord that includes a plurality of spaced loops, whereby the upper longitudinal portion of each panel is operatively secured with a loop. A particularly suitable fastener module is described in co-pending application Ser.

Shown in the drawings and described hereinbelow in detail are preferred embodiments of the invention. It is understood, however, that the present disclosure is an exemplification of the principles of the invention and does not limit the invention to the illustrated embodiments. For ease of description, the window covering embodying the present invention is described in its usual assembled position as shown in the accompanying drawings, and terms such as upper, lower, horizontal, longitudinal, etc., may be used herein with reference to this usual position.
- A window covering according to one embodiment of the present invention is described with reference to
FIGS. 1-3 . Window covering 10 includes ahead rail 12 including a control mechanism, such ascord lock 14, adapted to control raising and lowering of an opening member, such asopening cord 16, which is suspended from thehead rail 12. A securement member, such assecurement cord 18, is also suspended from thehead rail 12. Thesecurement cord 18 and theopening cord 16 pass down the back of the window covering 10.Securement cord 18 preferably includes a plurality of spacedloops 20. A plurality of intermediate panels 22 a-e and alowermost panel 22 f are secured with thesecurement cord 18 about an upper longitudinal portion 24 of the panels 22 such as at some of the spacedloops 20. The panels may be made of a woven or nonwoven fabric, paper, laminate, film, or the like. The panels are freely suspended from thesecurement member 18 such that a lower longitudinal portion 26 a-f of the panels 22 a-f are not connected with thesecurement member 18 or the openingmember 16. Thelowermost panel 22 f of the plurality of panels is secured with the openingmember 16 about an upperlongitudinal portion 30 of thelowermost panel 22 f. Abottom rail 28 may also be secured withlowermost panel 22 f. The intermediate panels 22 a-e are not secured with the opening member. Avalance panel 44 is also provided. Thisvalance panel 44, which has the same basic construction as panels 22 and includes astiffening strip 45, is clipped directly to thehead rail 12, and is not otherwise connected with the panels 22 a-f. - The panels 22 a-f overlap one another such that no light is able to pass through the window covering 10 when in the closed position. Also, the overlapped panels 22 a-f conceal the opening
member 16 and thesecurement member 18 extending behind the panels when viewed from the face of the window covering 10. - Each of the intermediate panels 22 a-e also preferably includes a weighted edge member, such as stiffening
strips 32 a-e, positioned about the lower longitudinal portion 26 a-e.Bottom rail 28 acts as the weighted edge member for thelowermost panel 22 f. The stiffening strips 32 a-e andbottom rail 28 are suitable for exerting gravitational force on the panels 22 a-f such that any bias in the material, such as from weaving or coatings, is overcome and the panels 22 a-f hang straight down. This weighted edge members may also take the form of a rod, rolled material, clips, or the like. - To open the window covering 10, a user pulls or retracts the opening
member 16, which draws upwards thelowermost panel 28 while the remaining panels remain in a resting position. Referring toFIG. 4 , thelowermost panel 22 f slides upwards substantially parallel to and behind an upperadjacent panel 22 e. By continuing to retract the openingmember 16, the upperlongitudinal portion 30 of thelowermost panel 22 f contacts the upperlongitudinal portion 38 of the upperadjacent panel 22 e. Thelowermost panel 22 f is therefore no longer able to move upwardly relative to the upperadjacent panel 22 e. As the openingmember 16 is retracted further, thelowermost panel 22 f and the upperadjacent panel 22 e are moved together behind the next upperadjacent panel 22 d. The panels 22 a-f are rearwardly stacked in this manner as the openingmember 16 is retracted until the panels 22 a-f are rearwardly stacked as shown inFIG. 5 . - As is shown, the rearward stacking of the panels provides a window covering 10 wherein the vertical and straight profile of the panels 22 a-f is maintained as the window covering 10 is opened. Accordingly, the aesthetic appearance of the window covering 10 is largely kept consistent whether the window covering is in a fully closed (
FIG. 1 ), partially opened (FIG. 4 ) or fully opened position (FIG. 5 ). - Referring to
FIGS. 6 and 7 , as the panels 22 are stacked, thesecurement cord 18 is folded or gathered behind the face 42 of the window covering 10. The openingmember 16 holds the panels 22 a-f in position by locking the control mechanism, such ascord lock 14. Since the overlapping relationship of the panels 22 a-f is maintained in the closed, partially opened, and fully opened positions, thesecurement cord 18 is not seen from the front of the window covering. - Panels 22 a-f are preferably detachably secured with the
securement cord 18 withfastener modules 46. An exemplar of asuitable fastener module 46 is shown inFIG. 8 .Fastener module 46 includes abuckle 48 and aclip 50, and is preferably made of a resilient material, such as a thermoplastic resin, lightweight metal, or the like. Theclip 50 is securable to an anchor member, such asdowel 52 associated with the panel (FIG. 6 ) by way of frictional engagement or by a mechanical force applied by theclip 50, such as exerted by the resilient properties of the material making up theclip 50.Buckle 48 includes ahousing 54 and an engagement member, such astransverse rod 56.Transverse rod 56 includes a first end, which is secured to or integral with thehousing 54, and asecond end 62, which is engageable withtab member 64 by urgingsecond end 62 throughhole 66. Where detachable fastener modules are used, it is also possible to have one or more panels entirely detachable. - The
securement cord 18 is engaged withfastener module 46 by way oftransverse rod 56, which is passed through a loop in the panel, such a loop 20 (FIG. 2 ) defined bysecurement cord 18. Openingcord 16 is passed throughhousing 54 offastener module 46, but is not secured thereto. As such, as openingcord 16 is retracted or extended, is passes throughhousing 54 and moves freely relative thereto such that thefastener module 46 acts as a cord guide for openingcord 16. - An alternative embodiment of the present invention is described with reference to
FIGS. 9-14 . Window covering 110 includes ahead rail 112, avalance panel 144, and plurality of panels 122 a-f. Thevalance panel 144 and the other panels 122 a-f overlap one another such that a gap free face is provided. The appearance of the alternative embodiment of the window covering 110 in the closed position as shown inFIG. 9 is substantially the same as the previous embodiment. However, the operation of window covering 110 is somewhat different in that rather than only opening the window covering 110 by raising panels, the window covering 110 may be opened by lowering panels as well. - Referring to
FIGS. 9-11 , additional features of window covering 110 are shown. The plurality of panels 122 a-f are suspended by control members from thehead rail 112. Theuppermost panel 122 a, which defines anuppermost portion 130 a is secured with a first opening member, such asfirst opening cord 117, which is adjustably controlled by cord lock 119 (FIG. 10 ). A securement member, such as securement cord 118 secures theuppermost portion 130 a of theuppermost panel 122 a with the uppermost portions 130 b-f of theother panels 122 b-f. - A lowermost panel 122 f of the plurality of panels is also secured with a second opening member, such as
second opening cord 116, about an upper longitudinal portion thereof 130 f. Thesecond opening cord 116 is suspended from thehead rail 112 and is controllably adjusted with a control mechanism, such as acord lock 114. The other panels 122 a-e are not secured with thesecond opening cord 116. - Opening window covering 110 may be accomplished in a number of different manners. One way is to pull on
second opening cord 116 to raise lowermost panel 122 f, such as described in the embodiment ofFIGS. 1-7 . Alternatively, window covering 110 may also be opened by lowering theuppermost panel 122 a by lowering thefirst opening cord 117. Referring toFIG. 12 , as thefirst opening cord 117 is lowered, intermediate panels 122 a-e are lowered relative to the lowermost panel 122 f such that the panels, such aspanels first opening cord 117 is fully lowered, the panels 122 a-f are stacked at the bottom of window covering 110 such as shown inFIG. 13 . - The
first opening cord 117 and thesecond opening cord 116 may also be operated in conjunction with one another. For example, as is shown inFIG. 14 , thefirst opening cord 117 has been partially lowered such thatpanel 122 e is stacked with the lowermost panel 122 f.Second opening cord 116 has also been raised such that lowermost panel 122 f andpanel 122 e are stacked withpanels - Yet another embodiment of the present invention is shown with reference to
FIGS. 15-18 . Similar to the previous embodiment, as shown inFIG. 15 , the window covering 210 includes ahead rail 212, an openingmember 216, avalance panel 244 and a plurality ofpanels 222 a-f. However, referring toFIGS. 16 and 17 , the panels are grouped into two sets. In particular,panels panels 222 b, 222 d, and 222 f are the other set. This variation provided the optional feature of sliding a first set of panels, such aspanels 222 b, 222 d, and 222 f relative to a second set, such aspanels first opening cord 216 is secured to the upper longitudinal portions ofpanels Panels 222 b, 222 d, and 222 f are secured to securement cord 218. Panel 222 f is also secured to asecond opening cord 217. - By pulling on
first opening cord 216,panels valance panel 244 andpanels 222 b and 222 d, respectively. Retractingsecond opening cord 217 causes lowermost panel 222 f to raise and open the entire window covering 210 such as discussed above. - Yet another variation of the present invention is shown in
FIG. 19 . In this embodiment, thepanels 322 a-e of window covering 310 are grouped into two groups. A first group consists of panels 322 a and 322 b and the second group consists of panels 322 c-e. The upper longitudinal portion ofpanels 322 e and 322 b are secured with afirst opening cord 316.Panels 322 a, 322 c and 322 d are secured with a securement cord 318. Lowermost panel 322 f is secured to asecond opening cord 317. In this embodiment, asfirst opening cord 316 is raised,panels 322 e and 322 b are raised and slid behindpanels 322 d and 322 a, respectively. As thefirst opening cord 316 is further raised, panels 322 a and 322 b are stacked behindvalance panel 344, andpanels panels 322 a-f may be raised by raising thesecond opening cord 317. - Alternatively, the upper longitudinal portion of the panel 322 b can be connected to a first opening cord while the upper longitudinal portion of the
panel 322 e is connected to a second opening cord, and the upper longitudinal portion of the lowermost panel 322 f is connected to a third opening cord. The panel 322 b can be thereby opened independently from thepanels - In the embodiments described, the panels are described as being uniform in size. However, it is also possible that the panels are of incrementally narrower widths such that the panels when stacked complete conceal the stacked panels.
- The foregoing description and the accompanying drawings are illustrative of the present invention. Still other variations and arrangements of parts are possible without departing from the spirit and scope of this invention.
