BACKGROUND OF THE INVENTION The present invention relates to a hanger for supporting pleated drapery on a conventional support structure, such as a drapery rod.
Drapery is in widespread use for covering or, at times uncovering windows, thereby adding to the decor of a room, and to the comfort of the occupants. Frequently, the drapery is sewn so that it has a series of pleats or gathers near its top, and drapery hangers have been provided in many forms, which drapery hangers engage and support a drapery, and are in turn supported on a drapery rod or similar support device.
A number of specific constructions of such drapery hangers have been heretofore proposed. Among the most noteworthy examples are the following. Kirsch U.S. Pat. No. 1,876,061 discloses a generally S-shaped hanger having an upwardly pointed leg for penetrating into the fabric, and a downwardly facing hook for support by a drapery rod. Yeidel U.S. Pat. No. 1,820,997 is generally similar, but is somewhat more elaborate in that a clamping action is effected between a pair of integral bight-connected legs, and a series of three additional legs provide a hook and a connecting leg between the hook and one of the noted pair of clamping legs. Solomon U.S. Pat. No. 2,524,403 discloses a drapery hanger in which a leg has an upwardly directed hooking pin at its lower end, and is joined to a twolegged supporting hook by an intermediate leg between the leg with the hooking pin and the adjacent leg of the supporting hook for engaging the drapery rod.
All of the above-discussed prior art devices were made of a continuous piece of wire, bent to the desired shape.
In addition to the above known drapery hangers, Gass U.S. No. 3,633,251 discloses a drapery hanger which is characterized by a relatively long middle leg having on one side of it an end leg which is of lesser length than the middle leg, this end leg having a barb at its lower end extending toward the middle leg, the middle leg having at its lower end a bight portion to which an upwardly extending leg is connected on the opposite to the first mentioned leg, this second end leg supporting a downwardly opening hook, for engaging a drapery rod or element thereof.
Experience with the lastmentioned prior art drapery hanger shows that while it was a substantial improvement over its predecessors, in certain instances it was found to grip the drapery fabric less securely than was desirable, this occurring when the drapery pleating had been sewn on certain types of machines which provided single rather than double stitching. In addition, in practice the last mentioned drapery hanger had been formed of a continuous piece of wire, making it somewhat difficult to manipulate in order to remove the hanger from the drapery, due to the stiffness of the wire and the small diameter thereof which led to hurting of the fingers of a person manipulating such drapery hanger. In addition, the continuous wire drapery hangers of the prior art are somewhat expensive to manufacture, requiring a number of manipulative and processing steps between the handling of the raw material, wire coiled on a spool, and the delivery of the finished product, a pointed, shaped and plated wire hanger. Further, the known wire drapery hangers have suffered the deficiency of being comparatively expensive to ship due to their weight, costly due to the fact that comparatively expensive metal is required, and, in use, of the deficiency of tending to rustafter a period of time, particularly in climates where moisture and salt air are present.
In addition to the above, while the noted drapery hanger disclosed in Gass. No. 3,633,251 was suitable for hanging almost the entire width of the draperies. it was found in practice that the drapery hangers therein disclosed could not readily be used in connection with th e hernmededges of the drapery panels.
SUMMARY OF THE INVENTION The present invention provides a drapery hanger which is molded of suitable plastic material by conventional injection molding techniques, the drapery hanger including a central longitudinally extending stem which is provided at its upper end with a bight portion, there being a clamping leg depending from the bight portion and extending generally parallel to the stem, but being shorter than the stem. The clamping leg is preferably arcuate in the longitudinal direction, so that its end portions are relatively closer to the stem, and its intermediate portion is removed from the stem: this configuration enables the drapery hanger to be readily distorted so as to provide a relatively easy release of the drapery from the present invention drapery hanger. The clamping leg is provided with a series of teeth that are adjacent the stem, and extend from the clamping leg toward the stem. More particularly, the teeth are inclined upwardly, and comprise two sets, the teeth of one set having their bases on one side of a central plane passing through the clamping leg and the stem, and the teeth of the other set having their bases on the opposite side of the central plane. The points of the teeth of both sets lie substantially on the central plane. The lower or free end of the clamping leg is directed downwardly, and is pointed, to enable the clamping leg to penetrate between hemmed layers of fabric, to enable the present invention drapery hanger to engage with the hemmed margin of a drapery panel. In an alternate embodiment, an additional series of teeth are provided on the stem, extending generally toward the clamping leg. Whether one or two series of teeth are provided, the latter being useful for heavier drapery, the multiple teeth provide greater assurance of engagement of the fabric, no matter what stitching equipment is used for sewing the pleats, and the release of the drapery hanger is facilitated by the comparatively greater flexibility of the plastic material and the greater dimensions thereof, avoiding the hurting of fingers of the operators.
The present drapery hanger, while providing multiple teeth, is less apt than previous drapery hangers to tear delicate fabrics, due to the fact that the resiliency of the plastic material permits a greater separation of the clamping leg from the adjacent leg, with greater ease than heretofore.
The hook for engaging the drapery rod or drapery rod element is provided by an outwardly and downwardly directed leg extending from the stem at about the middle portion thereof, the hook leg being made to extend directly from the stem and being integral therewith.
In alternate embodiments, the clamping leg is the same length as the stem, and may have a blunt end to avoid tearing fabric. The hook leg extends horizontally, or nearly so, from the stem, and has either no fillets, or very small fillets. The teeth extend either the full length of the clamping leg, or only along the upper portion. Further, a reenforcing element may be provided in the molded plastic drapery hanger.
Among the objects of the present invention are to provide an improved drapery hanger which will provide secure engagement with pleated drapery made on differing types of stitching machines, and a further object of the present invention is the provision of a drapery hanger having a central stem with a hook-leg integral therewith and extending directly therefrom. Yet another object of the present invention is to provide a drapery hanger which, while providing security of attachment to the drapery, may be readily and conveniently dis-engaged from the drapery. A further object of the present invention is the provision of a drapery hanger which can be used either for intermediate support of a drapery, at the pleats thereof, or at the hemmed edge of a drapery panel. A still further object of the present invention is to provide a drapery hanger which is more economical than previous similar drapery hangers, being made of less expensive material by less expensive manufacturing processes. A still further object of the present invention is to provide a drapery hanger which is less likely to tear delicate fabrics, which is rust-proof, and which is of light weight to provide for lower shipping costs.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to the drawings, wherein like or corresponding parts are designated by like or corresponding reference numerals throughout the several, views, there is shown in FIG. 1 a drapery hanger generally designated 20, made of a single integral plastic piece which has been injected molded by conventional methods. The hanger 20 comprises a longitudinally extending stem 21 having at its upper end a bight 22, and having a free lower end 23. A generally arcuate clamping leg 25 has its upper end integral with the bight 22, and a downwardly directed point 26 at its free or lower end. Clamping leg 25 is adjacent and in spaced relation to thestem 21, and in the space thereby provided there is a series of teeth 27 which extend outwardly of the leg 25, and toward the stem 21. One end tooth of the series 27 is adjacent the free end of the clamping leg 25, and in the preferred form as shown, the teeth are relatively closely spaced, the series of teeth extending upwardly along the clamping leg 25, stopping short of the interior of bight 22.
Referring now to FIG. 2, there is shown a view of the clamping leg 25, looking toward the above-noted series of teeth 27. A central plane P is indicated, which is parallel to the plane of view of FIG. 1, and passes centrally through the leg 25 and stem 21. The central plane P is also indicated on FIG. 3. One set of teeth 27A has the bases of the teeth lying on one side of the central plane P, and another set of teeth 27B have their bases lying on the other side of central plane P. The ends of all of the teeth lie substantially on the central plane P.
The above described relationship is also clearly visible in FIG. 3, which may also be seen to show the somewhat triangular shape of the teeth, and the generally elliptical cross sectional shape of the drapery hanger 20 at the location of the line 3 3 of FIG. 1.
Referring again to FIG. 1, a leg 30 extends generally downwardly and outwardly from the stem 21, extending from the opposite side of stem 21 as does the clamping leg 25: it will be understood that the central plane P passes through the central part of leg 25, stem 21 and hook leg 30. Hook leg 30 is, as will be understood, integral with the stem 21 and extends directly from the middle portion of the stem 21, in the preferred form, but in any event, extends from the stem 21 above the lower end 23 thereof. The hook leg 30 has a lower end 31 which is inserted through a suitable support element of a support rod or the like, the support element ultimately supporting the hanger 20 by engagement with the bight 32 formed between a lower fillet 24 and the inner portion of the leg 31. There is also provided a strengthening fillet 28 in the region of the connection of the leg 30 to the stem 21, which provides strength against lateral distortion and breakage through bending of the leg 30.
Referring now to FIG. 4, the molded plastic drapery hanger 20 is shown in distorted position, to which it may be moved in order to conveniently release the drapery. The arcuate clamping arm 25, which in the normal position shown in FIG. 1 has its upper and lower ends relatively closer to stem 21 and its intermediate portion relatively further therefrom, is thereby strengthened so that it will not bend along its length when the stem 21 is grasped, as adjacent fillet 28 in one hand, and the clamping leg 25 is grasped in the other hand, and is both swung away from the stem 21, and twisted so that the lower end 26 no longer lies in the above noted central plane. This release positioning of the drapery hanger is permitted by the resiliency of the material and the configuration as above noted, where the bending forces are directly applied to the bight 22, which is the most flexible portion of the drapery hanger 20. This permits the teeth 27 to be relatively widely separated from the stem 21, thereby achieving ready release of the drapery. As will be understood, the clamping leg has been moved generally as shown by the arrow A.
In shops and plants which fabricate drapery from suitable textile material, pleats are sewn by folding a portion of the material against another portion of material, and the stitching made on an appropriate sewing or stitching machine at the proper place. FIG. 5 illustrates a drapery D which has been folded in an initial stage to form a loop L, and there having been applied a double stitch S. The double stitch S results where a conventional stitching or sewing machine of the Gelman type is used. Where drapery is manufactured as shown in FIG. 5, the stitching S, shown in FIG. 6, is relatively close together, and as a consequence there are provided a number of places where a single barb of a drapery hanger can become engaged in order to support the drapery. With such drapery D, prior art drapery hangers were satisfactory. On the other hand, there is shown in FIG. 7 and 8 a drapery D having a similar loop L formed therein with a single stitching S, formed by another well known drapery sewing machine, known as the Friedman machine. Referring to FIG. 8, the stitching S will be seen to be much more widely spaced than was accomplished on the Gelman machine as shown in FIG. 6, and in such drapery D, the engagement of a single barb drapery hanger of the prior art was much less certain. As will be understood, due to the series 27 of teeth provided by the drapery hanger 20, the engagement will be positive and safe on either the drapery D or drapery D.
Referring now to FIG. 9, there may be seen the rear of a drapery panel 40, with the portion shown being of the hemmed edge 41 thereof. There are thus provided two layers of fabric which are in tight engagement with each other due to the stitching 42. While known drapery hangers could not be used for the hemmed end of the drapery panel, the drapery hanger 20 of the present invention, having on the clamping leg 25 a downwardly directed point 26 is able to penetrate between the tightly engaged fabric layers. This is shown in FIG. 10, where the point 26 of the clamping leg 25 has been inserted between the fabric layers, and thereby will be able to be forced between these layers, with the result that the drapery hanger 20 is useful not only at intermediate points of support for the drapery panel, but also at the hemmed end thereof.
Referring to FIG. 11, a drapery hanger 50 is shown in elevation, drapery hanger 50 being different from drapery hanger 20 in that on the portion of the stem 51 thereof which is opposite the clamping leg 55, thereof, there are a series of teeth 58 which extend toward the clamping leg 55, and are generally upwardly inclined. Clamping leg 55 is provided with teeth 57, generally similar to clamping leg 25 of the drapery hanger 20. The drapery hanger 50 has all of the features and therefore advantages of the drapery hanger 20, and in addition is capable of supporting heavier drapery, due to the fact that it is provided with both the series 57 of teeth and series 58 of teeth.
The drapery hangers 20 and 50 are of greater thickness than heretofore known drapery hangers made of metal wire. Typically, such wire drapery hangers had a diameter of approximately one sixteenth inch, while the thickness of the present invention molded plastic drapery hanger is substantially twice that, thereby permitting the present invention drapery hangers to be distorted, particularly as shown in FIG. 4, without significant discomfort to the operator, due both to thethickness of the hangers 20 and 50 and to the lesser resistance to bending and torsion thereof, in comparison to the known metal wire drapery hangers.
Referring now to FIG. 12, there is shown a drapery hanger 60 which is of molded plastic, and which com prises a generally straight stem 61 having at its upper end a bight 62, integral with which is a clamping leg 65, having substantially the same length as the stem 61. Clamping leg 65 is preferably straight, and at its lower or free end 66 is blunt. As in the previous embodiments, the clamping leg is adjacent and in spaced relation to the stem, and in the space thereby provided is a series of teeth 67 which extend outwardly of the leg 65, toward the stem 61. The series of teeth 67 extend substantially the entire length of the clamping leg 65. A downwardly opening hook leg 63 which extends on the opposite side of the stem from the clamping leg 65, hook leg 63 having a first, generally horizontal portion extending substantially at right angles, or at only a slight incline from a right angle, this first substantially horizontal portion being designated 64. The portion 64 is of substantially the same transverse dimension as is the stem 61, and preferably the entire hook leg 63, the stem 61 and the clamping leg 65 are all of substantially the same transverse dimension. Adjacent the substantially horizontal portion 64 of hook leg 63 is an arcuate portion 68 which leads to a generally downwardly extending portion 69, which preferably has a somewhat reflex curve, as shown. It is to be noted that the hook 63 is connected directly to the stem 61, and is not provided with fillets at its connection thereto. The end portion 69 is inclined away from the stem 61, and extends downwardly for a length such that it is approximately even with the stem 61.
The drapery hanger 60 as shown in FIG. 15 is preferably constructed without fillets where the portion 64 joins the stem 61, but in practice very small fillets may be utilized. The construction as shown in FIG. 12 permits the ready insertion of the hook leg 63 into an opening in a supporting structure, such as the slider of a draw drapery rod. It has been found that these openings are usually of limited size, and intended primarily for the reception of wire drapery hangers, so that to enable the utilization of existing drapery hardware, the embodiment of the drapery hanger shown in FIG. 12 has been provided. Further, where draperies are supported by drapery hangers, which in turn are supported on a rod, the drapery extends as high as the upper level of the supporting rod, so as to cover it or conceal it from view, for aesthetic purposes. Consequently, at their top margins, such draperies tilt forward slightly, due to the inter-relationship of the support of the drapery hook, from the slider of the drapery rod. In practice, the degree of tilt is approximately five degrees from the vertical, this being necessary in order that the upper portion of the drapery is not in an interferring position in relationship to the drapery rod. The present construction, shown in FIG. 12, preserves this relationship, enabling the upper portion of the drapery to be inclined to the extent necessary to avoid interference between the upper portion of the'drapery and the drapery rod. Where in some instances, a pointed end on the clamping leg would engage the drapery fabric, when twisted in the manner illustrated in FIG. 4, to avoid this difficulty, theblunt end 66 has been provided on the clamping leg on the embodiment shown in FIG. 12. Thus, for insertion into portions of the drapery other than the closed end panels, the blunt end of the clamping leg, as illustrated in FIG. 12, is preferred, while maintaining the pointed end in connection with such closed ends of the drapery panels.
Referring to FIG. 13, there is shown a drapery hanger 70 which is generally similar to the drapery hanger 60 of FIG. 12, having a stem 71, bight 72 and clamping leg 75. However, the series of teeth 77 of the drapery hanger 70 extend only approximately one-half of the length of the clamping leg 75, beginning near the bight 72. Hence, the teeth 77 extend only in the upper portion of the clamping leg 75. The lower end 76 of the clamping leg 75 is shown pointed, although it will be understood, a substantially identical hanger could be provided with the free end 76 blunt, as is the free end 66. The hook leg 73 is of substantially the same shape as the hook leg 63, as is apparent. This embodiment of the invention provides security of holding of the drapery, while the lesser extent of the series of teeth permits more ready disengagement of the drapery hanger 70 from the drapery fabric.
Referring now to FIG. 14, there is disclosed a drapery hanger 80, which is shown to be substantially of the same construction as the drapery hanger 70, by way of example, and including the stem 81, bight 82, clamping leg 85 and series of teeth 87 extending along the upper portion of the clamping leg 85. The hook leg 83 is substantially identical to the hook leg 72. The drapery hanger 80 is characterized, however, by a reenforcing member 88 which. extends with the molded plastic drapery hanger 80. Preferably, the reenforcing element 88 is of metal, there being shown in FIG. the cross sectional shape of the reenforcing element 88, which is a generally flat, rectangular cross section. The reenforcing element 88 is preferably of metal, and extends substantially in the full length of the stem 81, through bight 82 and throughout the full length of the clamping leg 85, although the reenforcing element 88 may have a lesser extent, being provided only in the regions of major stress, such as throughout the bight 82 and into the stem 81 and clamping leg 85 for a lesser distance than the full lengths thereof. Further, in the hook leg 83, there may be provided a further reenforcing element 89. The reenforcing element(s) are of a suitable material stronger than the plastic, such as steel wire, or a steel band.
In FIG. 16 there is shown a drapery hanger 90 including the stem 91, bight 92, and clamping leg 95 of lesser length than stem 91, with teeth 97, thus being similar to the embodiment of FIG. 1. The hook leg 93 is substantially identical to hook leg 63.
There has been provided a drapery hanger which is made of molded plastic, and which is capable of greater security of attachment to draperies, no matter on which known drapery stitching machine the drapery has been 5 made. Further the molded plastic drapery hanger of the present invention provides for great economy of construction due both to the constructional feature of direct attachment of a hook leg to a stem, and to the utilization of more economical plastic raw material, in comparison to metal wire raw material, and further due to more economical plastic molding processes, in comparison to expensive and multi-step wire forming and plating processes. The present invention molded plastic drapery hanger may be utilized on both intermediate and end portions of a drapery panel, may be generally distorted to release position, and is less prone to tearing delicate fabric. Further, the present invention molded plastic drapery hanger is less subject to deterioration in moist and salt atmospheres, and is thereby more durable, while being less expensive.
It is further to be noted that the drapery hanger provided herein permits secure holding of drapery, while providing ease of insertion into standard drapery hardware, and also permits the upper portion of the drapery to assume a position relative to the supporting drapery rod which does not interfere therewith. The present invention drapery hanger herein provided will avoid tearing of drapery material when twisted so as to be disengaged therefrom, and is of sufficient strength so as to avoid breakage during manipulation.
It will be obvious to those skilled in the art that vari ous changes may be made without departing from the spirit of the invention and therefore the invention is not limited to what is shown in the drawings and described in the specification but only as indicated in the appended claims.
