Abstract
The no-sew window drapery system comprises tucking fabric into a rod. The rod has a profile that creates an opening across the entire length and sufficient space in the interior to accept the fabric. The rod may additionally incorporate a locking system to secure the fabric ends inside the rod. The fabric employed is fed into the opening created by the profile, arranged into the style desired and secured into place. Because of the characteristics of the plastic, and the close-fit force exerted on the fabric, the result is to provide a rod which holds the fabric in place. Yet it is easy to install the fabric without the need for any sewing and still give the fabric a customized look.
Description




FIELD OF THE INVENTION




This invention relates to styles for decorating or covering windows and, more particularly, to window treatment styles for creating valance and “topper” arrangements simply and inexpensively.




BACKGROUND OF THE INVENTION




As it is well known and understood, window treatment stylings are typically manufactured by skilled professionals who either have “ready-made” styles mass produced in which case the cost is low and the selection is limited, or have “custom” styles attained through a designer on an individual basis, in which case the selection is unlimited but the costs are extremely high. Also these window treatments are fairly permanent due to the sewing process involved. It would be advantageous, therefore, if a new and unique manufacture were available to make these applications more cost effective, and to provide a “custom look” easily and inexpensively with the additional advantage of being able to change the fabric or styling with little effort. In my U.S. Pat. Nos. 5,152,331 and 5,383,635, I have disclosed various techniques for providing window treatment, fabric wrapped tables and the like wherein the fabric is secured around a semi-soft foam in a no-sew wrap and tuck process. It would be advantageous through this invention to create drapery pole styles where gathered as well as flat fabric styles can be easily created.




SUMMARY OF THE INVENTION




As will become clear in the description that follows, the drapery system of the present invention accepts the same types of coverings as now available in the industry, and allows for a multiplicity of designs, by inserting fabrics in different stylings and by combining different shapes of decorative hardware. As will also be seen, the window treatment will be easy to create without any sewing and just as easy to install, using a simple screw-in device. As will also become clear from the description below, the window treatment of the invention is reusable, allowing an easy change of fabrics and or stylings, all in an easy, fast and inexpensive manner.




More particularly, and as will be seen from the description below, the window treatment of the invention follows from the use of a plastic rod or length whose profile allows for the insertion of fabric. The rod utilized will be seen to be designed as a particular profile which creates an opening across the length of the rod. The fabric employed will be seen to have its ends fitted through the opening of the profile so that they are stored inside the rod. Because of the characteristics of the rigid plastic, having the ability to stretch open enough to insert the fabric, yet exerting enough pressure against the fabric after it is installed to be secured into place, the end result is to provide a rod which holds the fabric in place. Additionally, the profile may provide for a method of locking or closure of the ends to further secure the fabric in place. And because of these characteristics, the window treatment can thus be completed without the need for any “sewing” whatsoever, so as to provide a customized look easily and inexpensively.




As will also be seen, by using such a drapery system of the invention, it then becomes possible, and as will be more fully described below, to design and arrange the treatment in different stylings as well as to combine different lengths and decorative hardware to create modern, traditional, or other arrangements or stylings according to one's preference.

DETAILED DESCRIPTION




Referring now more particularly to FIGS.


1


-


3


, system


10


includes a plastic profile


12


of pre-determined shape and dimension, cut to any length desired, either by the purchaser of the rod, or by the manufacturer of prearranged treatments. The rod profile shown in use (

FIG. 1

) is of hollow tubular form into which fabric


14


is tucked through the opening


16


so that the fabric may be stored in the interior cavity


18


of the profile. The fabric may be doubled over, with the raw ends inserting into slit


16


as to give a finished look. See

FIGS. 1 and 1A

.




Fabric


14


or the like may be styled flat and smooth or gathered and ruffled into place while the profile is in the open position (

FIG. 2

) and then fixed into place when put into the closed position (FIG.


3


). While the insertion and arrangement of fabric can be done by hand, the use of a straight edge, such as a ruler may also be utilized. But by employing a rigid plastic of polyvinylchloride, for example, the fabric


14


will be held in place, especially when profile


12


with opening


16


and cavity


18


is of a particular shape to exert pressure on fabric


14


and close in a locked position to keep the fabric in place. Such polyvinylchloride plastic may have a wall thickness between 0.020 and 0.070. Other rigid materials and thicknesses may be used for rod or profile


12


. Preferably the material should be sufficiently rigid to be shape retaining but capable of being distorted out of its shape and then have enough resiliency to return toward its undistorted shape.





FIG. 1A

shows the interlocking relationship between the fabric


14


and the tubular profile or rod


12


. As shown therein, and as also shown in various other figures, the slit


16


is defined by a pair of generally parallel spaced edges. One of the edges has a guide surface


13


and then bends up and around to terminate in an offset portion


15


which is generally parallel to the guide surface


13


. This forms the U-shaped edge best shown in FIG.


2


and into which the fabric


14


would be inserted. The other edge which forms slit


16


is the locking edge


17


which likewise is generally parallel to a guide surface


13


and offset portion


15


. When the fabric has been insected into the slit


16


by being pushed into the U-shaped edge formed by guide surface


13


and offset portion


15


, the hollow rod is squeezed so that the locking portion


17


may be moved outwardly beyond surface


13


and squeezed sufficiently downwardly to be located directly in line with the U-shaped edge. Upon release of pressure the locking edge then enters the U-shaped edge and presses into the fabric


14


as illustrated in FIG.


1


A. Accordingly, the fabric


14


is forced to assume a tortuous path wherein the fabric is locked between guide surface


13


and locking portion


17


and then is located around locking portion


17


between locking portion


17


and offset portion


15


. Finally, fabric


14


extends over and around offset portion


15


and into cavity


18


.




The invention may also be practiced by covering the rod


12


with a fabric.

FIG. 1B

, for example, shows how a fabric


14


A may be wrapped around rod


12


prior to the application of fabric


14


. As shown therein fabric


14


A, after being wrapped around rod


12


is held in place in slit


16


by wrapping around the slit edges


13


,


15


and


17


.

FIG. 1C

shows an alternative where fabric


14


is wrapped rod


12


and locked in slit


16


while hanging downwardly to form the drape.




When it is desired to remove the fabric, the reverse procedures are used wherein the rod


12


is squeezed to move locking portion


17


outwardly from being within the U-shaped edge. The rod is released when locking portion


17


is again above offset portion


15


as shown in FIG.


2


. This permits the fabric to be removed and a new fabric to be inserted.




As will be appreciated, such rod


12


of the invention requires no saving to hold fabric


14


in place, can be cut to measure and can be easily disassembled to change fabric stylings as desired at later times.




As is apparent from the above description and from

FIGS. 1

,


1


A,


2


and


3


the slit


16


includes a U shaped edge which forms an open channel between guide surface


13


and offset portion


15


. The open channel is exposed to the exterior to permit a fabric


14


to be placed in the open channel and extend around offset portion


15


. Offset portion


15


is thus spaced from the inner surface of the rod


12


a sufficient distance to accommodate the fabric


14


. As best shown in

FIG. 1A

, offset portion


15


is substantially shorter in length than the length of guide surface


13


to permit the creation of the open channel, and yet provide the sufficient clearance which is needed. The above figures also clearly illustrate that the U shaped edge is oriented transverse to a tangent to the generally closed periphery of rod


12


over the remainder of the rod.

FIG. 1A

for example, shows the fabric


14


to be in a tangential relationship with the periphery, while the U shaped edge formed by guide surface


13


and offset portion


15


and the straight locking edge


17


are generally transverse to that tangential direction. As also illustrated in

FIG. 1A

, slit


16


extends radially from the center of the rod


12


. As further shown, locking edge


17


is of sufficient length relative to offset portion


15


so that the locking edge extends beyond the spacing between the inner surface of rod


12


and offset portion


15


, and the locking edge


17


extends sufficiently into the open channel. These relative lengths permit the locking edge


17


to be easily withdrawn from the channel upon a squeezing of the rod


12


, as previously described.




The invention may broadly be practiced where the slit


16


omits the offset portion


15


. In such practice, the slit could be distorted by moving locking portion


17


away from guide surface


13


to enlarge the size of slit


16


. After the fabric has been inserted over guide surface


13


, locking portion


17


is released and presses against the fabric to hold the fabric in slit


16


.




While rod


12


is shown as circular in cross section, other shapes such as oval, square, rectangular, etc. may also be used.




As will be apparent, some window treatment designs, according to the size needed, might require the rod lengths to be joined as shown in FIG.


4


and because of the flexibility or resiliency of the rigid plastic rod


12


, this can be accomplished by inserting one rod inside the other so the profile shapes interlock with one another and create system


10


A.




In

FIGS. 5A and 5B

, show two methods for installing the window treatment of the invention. There, fastening members, such as screws


20


or


20


A are installed into the wall or other support structure either above or on the window molding, with the bent end, as shown, either hooking into the opening


16


at any place across the rod as shown in

FIG. 5A

, or by cradling the rod


12


to support it from the bottom as shown in FIG.


5


B.




FIGS.


6


A-


6


C illustrate different treatments to finish off one or preferably both ends of a rod. The end piece is preferably made of the same or like material which has been cast, molded or extruded into a particular shape. Such shapes may be employed at the rods ends by fitting the treatments either over the edges of the rod profile


12


as end cap


22


shown in

FIG. 6A

or by inserting a projection into the cavity


18


, as finials


24


shown in

FIG. 6B

or by inserting the elbow


26


, which is made from the same profile shape, into or over the rod


12


, the same way one would connect rod lengths, as shown in FIG.


6


C.





FIG. 6D

shows an alternative where the finial


24


A has a cavity instead of a projection. A fabric


14


A is wrapped around finial


24


A and then tucked into the finial cavity. The fabric wrapped finial is then telescoped over rod


12


and thereby mounted to rod


12


. End pieces


22


and


26


may also be modified to be wrapped by a fabric, such as by having a cavity into which the fabric would be tucked with the end piece telescoped over the rod. The wrapping of the fabric and the securing of the end piece to the rod may be accomplished in other manners in accordance with the invention.




While there have been described what are considered to be the preferred embodiments of the present invention, it will be readily appreciated that modifications can be made by those skilled in the art without departing from the scope of the teachings herein. Thus, while a profile


12


with opening


16


and cavity


18


has been described for accepting the fabric


14


, any shaped profile with sufficient opening and interior space can be employed as long as there is exertion on the fabric


14


enough to hold it in place. In similar fashion, while the opening


16


preferably extends the entire length of the rod


12


, it will be seen that in an actual construction, all that is necessary is that the ends of rod


12


have a sufficient opening enough to accept the insertion of fabric


14


.




In the preferred practice of this invention the profile rod


12


is of completely hollow tubular form. This permits a rigid material to be used while still having sufficient springiness or resiliency to permit a squeezing and locking action to take place for inserting and holding the fabric in place. The invention in its broad sense, however, may also be practiced where some or all of the interior is solid and a tortuous path is created between a guide surface, a locking portion and an offset portion having the physical relationship shown in FIG.


1


A and in FIG.


3


. In such practice it would be necessary to force the fabric into the slit and around the guide surface and then around the offset portion. The illustrated embodiment, however, is the preferred practice since it permits the fabric to be readily inserted into the open U-shaped edge and then locked in place by the springiness of the looking edge. Additionally, the completely open or hollow tubular form for the rod


12


provides the cavity for readily receiving the end portion of the fabric.




In the preferred practice of the invention the edges which form slit


16


are of continuous unbroken construction. The invention, however, may be practiced where the edges themselves are slit to form a plurality of spring fingers wherein one spring finger would be of U-shaped form to provide the guide surface


13


and offset portion


15


and the other spring fingers would be of generally planar form to provide the locking portion


17


.




Other variations of the invention will be apparent to one reading the specification herein.
