OER/Au A TTORNEY United States Patent 3,411,561 THREE-PIECE DRAPERY STRUCTURE Donald E. Mock, Covina, Calif assignor to Anjac Plastics, Inc., El Monte, Calif. Filed Dec. 29, 1966, Ser. No. 605,789 5 Claims. (Cl. 160-231) ABSTRACT OF THE DISCLOSURE This invention is directed to a three-piece drapery structure, and particularly to a three-piece drapery structure in which three different parts are attached together in such a way as to provide drapery panels which fold on vertical lines. The drapery structure of this invention comprises a drapery panel with appropriate members thereon for the attachment of a soft polymer composition material hinge and a retainer. The retainer is arranged to retain the hinge with respect to the drapery panel and preferably includes a retaining finger which is adapted to retain a decorative panel with respect to the drapery panel. Each of the three parts is preferably of uniform cross section so that they can be inexpensively manufactured by extrusion. Each of the parts is interrelated in such a manner that when attached together, all parts are retained in appropriate relationship. The drapery panel has a channel therein and a bulbous edge of the soft hinge is positioned in the channel. The retainer snaps over the edge of the channel to partially close the open side thereof and retains the bulbous rib on the hinge. The retainer includes a snap edge which snaps onto the drapery panel to be retained thereon and thus retain the hinge in position. The hinge is necessarily relatively flexible. The retainer is necessarily resilient while the drapery panel is preferably more rigid. These parts may be made of the same, suitable material, with wall thickness determining resiliency, or may be made of different materials of different resiliency.
Background Vertically oriented drapery panels and other blind.
panels are known. Some of them are in the form of structures like venetian blinds where each of the panels is separated from the other. Other drapery panels include complex and expensive structures which are attached to each other by various hand applied individual hinge means. These latter types usually have rather wide panels, on account of the cost and labor involved in the hinge means. Several decorative advantages are obtained from this three-piece drapery structure. These decorative advantages include continuous hinges, smooth rounded surfaces and coherent compatible appearance. This is obtained by proper interrelationship of the parts, and is absent from the prior art structures which do not rely upon continuous extrusions as parts. Thus, in addition to the functional advantages of the structure of this invention as compared to the prior art, it also has appearance advantages. Furthermore, the three-piece drapery'structure incorporates the provision of insertion of separate decorative panels. This incorporating structure also provides versatility which is absent from known prior structures. Another decorative panel installation structure is shown in Tsuhako Patent No. 3,277,952, granted Oct. 11, 1966.
Brief summary I Accordingly, it is an object of this invention to provide a three-piece drapery structure which is easily manufactured, readily installed and is of versatile use so as to provide drapery structure having wide use and economical life. It is a further object of this invention to provide a three-piece drapery structure which comprises a drapery "ice panel, a flexible hinge and a retainer related to the drapery panel, a flexible hinge and a retainer related to the drapery panel and the flexible hinge. It is still another object of this invention to provide a three-piece drapery structure which is of such nature that it can be readily assembled from inexpensive components and yet provide a highly ornamental, useful and decorative drapery structure. It is another object of this invention to provide a three-piece drapery structure which is fully opaque, without any light interstices when pulled to the extended position, yet folds into a relativelysmall space to leave a large opening, when so desired. It is a further object to provide a drapery panel which can be translucent or opaque or translucent with punched out patterns backed up by a decorative panel. It is another object of this invention to provide a drapery structure which folds upon uniform vertical lines and which is stressed to readily fold in the correct accordian pleated direction so that the drapery is readily closed and yet is easily extended. Other objects and advantages of this invention will become apparent from a study of the following portion of this specification, the claims and the attached drawing.

FIG. 2 is an enlarged section taken generally along the line 22 of FIG. 1 showing the drapery in the extended position.
FIG. 3 is an enlarged transverse sectional View of the hinge joint structure shown to the right side of FIG. 2, shown in the folded position.
FIG. 4 is an enlarged transverse sectional view of the hinge joint structure at the leftside of FIG. 2, shown in the folded position.
Detailed description Referring to the drawings, the three-piece drapery structure of this invention is generally indicated at 1.0. The drapery structure comprises drapery panels 12, 14, and 16 respectively joined by hinges 18 and 20. The hinges are retained in panels 12, 14, and 16 by means of retainers 22, 24, 26, and 28.
Considering the drapery panels in detail, each of the panels is identical and therefore for convenience, only panel 14 will be described in detail. As is seen in FIGS. 1 and 2, the panel comprises a relatively wide flat central panel 30 which is of such width as to define the overall width of the drapery panel 14. The upper side of central panel 30, as is seen in FIG. 2 which is the rear side in FIG. 1, can be a plain and undecorated surface of the extruded polymer composition material of drapery panel 14. For further decorative effect, it can be embossed, slotted, punched, or otherwise patterned. The central panel can be opaque, striated or translucent. When punched, it is preferably backed up by a decorative panel. The widthwise dimension of the central panel 30 is established as desired for the overall width of individual drapery panels. Each edge of the central panel has securing means thereon. These securing means comprise an H shaped structure in which the central panel forms one of the legs, or the flanges on one side of the H. Thus, central panel 30 extends into flanges 32 and 34, the edges of which define the termination of the central panel and the drapery panel 14. Webs 36 and 38 extend at right angles to central panel 30 and flanges 32 and 34. Flanges 40 and 42 are integrally formed with web 36 and extend parallel to central panel 30 and flange 32. Flange 40 extends substantially the same distance away from web 36 as does flange 32 to define channel 44. Channel 44 is open edgewise of drapery panel 14. Flange 42 extends a short distance inward beyond web 36 to create a securing edge.
Similarly, web 38 extends away from central panel 30 a short distance and has flanges 46 and 48 thereon. Again, flange 46 extends the same widthwise amount of the panel as flange 34 to define an outwardly opening channel 50. Flange 48 extends slightly inward from web 38 to define an inwardly directed securing or holding edge.
Hinges 18 and are also identical. They are simply arranged in opposite orientations with respect to drapery panel 14 in order to cause accordian folding of the panels when folding of the panels is desired. Referring to FIG. 3, the hinges are all illustrated by hinge 20 which has body 52, flanges 54 and 56 which are integrally formed with the body and flanges 54 and 56 which are integrally formed with the body and are thinner than the thickness of the body. Flanges 54 and 56 respectively terminate in ribs 58 and 60. The ribs 58 and 60 are of such thickness as to fit within channels 48 and 58, and rib 58 is shown as being positioned within channel 50. The channels are of suflicient depth that the ribs are fully inserted within the channels and a short length of the hinge flanges is within the channels. This reduced thickness of the flanges provides space for engagement by the respective retainers for retaining the ribs within their channels. The hinges are preferably extruded so that they have a naturally curved configuration. Thus, even while in the ex tended position, shown in FIG. 2, the bodies of the hinges are curved. The flanges are normally substantially parallel in an unstressed position, part way between the showings in FIGS. 3 and 4.
Retainers 22 through 28 are also each of identical construction. For convenience, retainer 22 will be described, as is shown in FIG. 4. Retainer 22 has a body 62 which terminates in retainer hook 64. Retainer hook 64 engages over the edge of the flange and extends into the channel in which a rib of one of the hinges is located. The retainer hook is of sufiicient thickness that it, together with the thickness of the hinge flange, substantially fills the open side of the channel. Thus, the retainer retains the hinge rib within the channel. Furthermore, body 62 has a latch hook 66 thereon. The body and the latch hook are of sufficient resiliency to permit the retainer hook 64 to be hooked into place in retaining position and permit the latch hook 66 to be snapped over flange 42 to retain the body in position. The flange 42 is rounded on the outside corners to aid in the snapping into place.
The described drapery structure is of uniform cross sections so that eachof the three parts thereof can be manufactured by extrusion of synthetic polymer composition material. However, each of the three parts have somewhat different requirements so that the materials are preferably of slightly physical characteristics. The drapery panels 12, 14 and 16 are preferably extruded from unplasticized polyvinyl chloride, unplasticized polyvinyl acetate or copolymers thereof. Such a structure is quite rigid and thus furnishes a relatively rigid form for each of the drapery panels. Hinges 18 and 20, however, must be highly flexible. Highly plasticized polyvinyl chloride, highly plasticized polyvinyl acetate and highly plasticized copolymers of these materials are suitable for this service. Furthermore, some of the polyolefins are also highly suitable. Within the polyolefin group, polyethylene and polypropylene are suitable. The hinges should have approximately the same flexibility as soft leather. Therefore, they are preferably quite limp.
With respect to retainers 22, 24, 26 and 28, they must both be sufiiciently flexible and resilient to snap into position and sufficiently strong so that they are not limp. Furthermore, the clamp finger on the retainers must have the necessary flexibility, and yet have a resilient retaining force for the decorative panels. Therefore, the same materials as are suitable for the hinge are suitable for this service, except that the vinyl compositions are not so highly plasticized to provide more strength to the materials. Other conventional material may be suitable for use in these various applications.
In the drapery structure 10 it is desirable that at least one side be able to be decorated in any desirable way to suit the decor of the room in which the drapery structure is to be hung. Thus, decorative panels can be placed upon one side of each of the central panels 30 For example, decorative panels 68, 70 and 72 are adapted to be placed against the central panel 30 of each of the drapery panels 12, 14 and 16, respectively. As is shown with respect to drapery panel 14, its decorative panel 70 is relatively thin and lies against one side of central panel 30. The width of decorative panel 70 is substantially equal to the distance between flanges 42 and 48 so that the panel 70 may be easily slipped into place. Referring to FIG. 4, retainer 24 is integrally formed thereon resilient clamp finger 74 which engages panel 70. A similar clamp finger is provided on each of the retainers to retain the decorative panels in place. Furthermore, the length of the clamp fingers is such, together with the resiliency and undeflected shape, that even in the absence of the decorative panel the clamp fingers are stressed toward the curved position to engage central panel 30. Thus, even in the absence of a decorative panel there is no gap at the edge of the clamp fingers. In view of the fact that the clamp fingers hold the decorative panels in place, it is clear that any reasonably thin decorative panel may be secured in place, and the decorative panels can be changed should the decor of the establishment be changed to require such a change. Of course, the three piece drapery structure 10 is hung in such a way that the decorative panel side is on the side on which it is most effective.
The manner in which the three-piece drapery structure 10 is hung is dependent upon the particular installation. As is indicated, track 76 is provided. Guides 78, 80' and 82 are respectively secured upon hangers 84, 86 and 88. These hangers are respectively secured to drapery panels 12, 14 and 16. As is illustrated, the hangers may be hinged together or may rely upon the hinges between the drapery panel to maintain them in position. The illustrated hanging structure is the preferred hanging structure and is disclosed in more detail in co-pending patent application Ser. No. 609,422, filed Jan. 16, 1967. The entire disclosure of that application is incorporated herein by this reference. The manner in which the drapery .panels fold in accordian pleats is determined by the orientation of the hinges 18 and 20 with respect to their adjacent panels. Alternate orientation of the hinges is shown. This alternate orientation, together with the internal stresses of them in the extended position cause the various drapery panels to fold into correct accordian pleated arrangement when the drapery structure is folded. If desired, as is disclosed in the above identified disclosure, hinges between the attachment members 84, 86 and 8S, and the other attachment members can limit the accordian folding to the desired direction.
