DRAPERY SUPPORT BACKGROUND OF THE INVENTION As seen in my U.S. Pat. No. 3,296,651, entitled Drapery Support, an improved fixture for hanging draperies comprises a plurality of drapery folding plates hinged together end to end, suspended from an elongated, rigid supporting rod or track, and carrying a drapery in such a way that the drapery, which hangs from the plates, can shift longitudinally on the plates. The drapery is provided with means by which it may be slidably attached to the folding plates and easily removed therefrom. With such a fixture, as the hinged folding plates are opened and closed, the drapery panels follow the contour of the folding plates and slide to a proper position to form the desired folds, without the use-of hooks or pleats. The folding plates are attached to carrier or slider members which traverse along the elongated track.
The present invention relates to a track and associated apparatus utilizing such folding plates, including improved carrier members, support brackets for the track structure, valance hangers, drapery attaching means, and other related features which will be apparent hereinafter.
SUMMARY OF THE INVENTION The present invention relates to drapery fixtures, and more particularly to apparatus for shifting draperies, or the like, along a traverse rod or track structure.
An object of this invention is to provide an improved traverse rod or track structure and cooperating slider or carrier members which support drapery folding plates of the character described.
Another object of this invention is to provide an improved traverse rod or track structure and cooperating support brackets. In one embodiment of the invention, the brackets have a snap engagement with the track structure, without additional holding or clamping means.
A further object of this invention is to provide an improved traverse rod or track structure and cooperating brackets for supporting a drapery valance or the like. In one embodiment of the invention the drapery valance brackets are snap fit onto the track structure, without additional means.
Yet another object of the invention is to provide means to insure that the drapery folding plates fold and unfold uniformly to prevent gathering of the drapery.
Still a further object of the invention is to provide new and improved means attachable to the drapery to snap fit the drapery onto the folding plates. In one embodiment, accommodation is made for relatively heavy draperies such as velvet or the like. In another embodiment, a friction drag is provided to limit the sliding movement of the drapery along the folding plates.
Another object of the invention is to provide a new and improved means for shifting the drapery along the traverse rod or track structure, including end fittings with interchangeable replaceable pulleys over which an operating cord passes for shifting the drapery, particularly a continuous or closed loop type cord. The pulleys include a control pulley at one end of the track structure and a return pulley at the other end of the track structure, said pulleys being selectively positionable at either end of the track structure so as to change the end of the track at which the free or operating end of the cord loop is located, without removing the cord or disassembling the track.
Other objects, features and advantages of the invention will become apparent from the following detailed description taken in connection with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION Generally, as shown in my US. Pat. No. 3,296,651, the traverse drapery support or fixture to which this invention relates includes a plurality of drapery hanging members or folding plates, generally designated 10, hinged together in end to end relation. The folding plates slide longitudinally along a rod or track structure, generally designated 12, to move a drapery between open and closed positions. The drapery is provided with sliders, to be described in greater detail hereinafter, which facilitates easy installation and removal of the drapery panels by simply snapping into longitudinal slots 14 provided in the folding plates. The draperies are self-positioned as a result of their sliding relation to the plates.
Referring to the drawings in greater detail, FIG. 1 shows a plurality of hinged drapery folding plates 10 slidably carried by the track structure 12. The plates are made of molded plastic or any other suitable material, and may vary in size or shape depending on the nature of the drapery installation. The embodiment of the invention shown in FIGS. 1 and 2 has folding plates with two spaced parallel faces in generally vertical planes forming an elongated straight center section 16, with complementary hinge sections 18 and 19 offset laterally at the ends of the plates and engageable to interconnect a plurality of plates end to end in an accordian fashion. When the folding plates are interconnected end to end, successive plates simply are inverted to enable the complementary end hinge sections to be joined. The hinge sections are provided with stop surfaces which limit the degree of opening of the plates.
The hinged drapery folding plates are suspended from the track structure 12 by an appropriate means which will permit the plates to move longitudinally along the track and to rotate with respect to the track. In the embodiment of the invention illustrated herein, track 12 has a longitudinal channel defined partially by flanges 22 (FIG. 3) in which a plurality of carrier members, generally designated 24 (FIG. 2), are received. Each carrier 24 has an internal recess 24a (FIGS. 2, 4 and 38) and a downwardly opening slot 24b. Selected ones of the plates 10 have a supporting pin 26 forming a neck portion extending generally vertically upwardly from the top of each of the folding plates and terminating in an enlarged head portion 28 which is received in the recess 24a of a carrier 24 (as best seen in FIGS. 4 and 38), with the head portion 28 resting at the bottom of the recess and overlying the sides of the slot 24b. The head portion 28 is free to rotate within the recess of the carrier member allowing the plates to pivot with respect to the track I2 asthe drapery is drawn back and forth along the track. The downwardly opening slots are elongated slightly, as best seen in FIG. 38, to permit limited fore and aft movement of the pins 26 (and thus the plates 10) relative to the carrier members 24 in a direction generally perpendicular to the track 12, for purposes to be described hereinafter. The supporting pins 26 preferably are provided on every other folding plate to prevent possible binding of adjacent plates and thereby provide free movement of the folding plates in folding and unfolding the draperies. At least one outer end or master carrier member, generally designated 30 (FIGS. 2 and 6) and to be described in greater detail hereinafter, is provided for connection to an appropriate operating cord for moving one end of a drapery panel to thereby fold and unfold the drapery.
As seen in FIG. 1, the track 12 is mounted on a wall or the like by latch type brackets, generally designated 32, to be described in greater detail hereinafter.
Once the track structure 12 and drapery folding plates 10 are installed, the invention is remarkably easy to use. The drapery panel nonnally is merely a rectangular panel of material which is suspended from the drapery folding plates by sliders which are snap fit into the dovetail slots 14. As the hinged folding plates are opened and closed, the drapery panels follow the contour of the folding plates and slide to a proper position to form the desired pleats or folds.
As seen in FIG. I, the support brackets 32 are generally L-shaped with a vertical portion 320 for attachment to a wall or the like and a horizontal portion 32b extending outwardly from the wall over the track 21 for attachment thereto by means of a latch member, generally designated 34. As best seen in FIGS. 3, l0 and 11, the track has a pair of longitudinally extending lugs or ribs 36a, 36b protruding upwardly from the upper surface of the track along the marginal edges thereof, and inwardly extending flanges 38a, 38b at the top of the lugs defining inwardly opening grooves 40a, 40b. The horizontal portion 32b of each bracket member 32 terminates in a shoulder 32c and a downwardly offset projection 32d (FIG. 11) extending into the front groove 40a to engage the flange 38a.
Referring to FIGS. 1, l0 and 1 I, the latch member 34 is pivotally mounted, as by a rivet 42, on the underside of the horizontal portion 32b of each bracket member 32 above the top surface of the track 12. The latch member 34 is generally flat and U-shaped with a bight portion 34a and a pair of leg portions 34b and 340. The latch member is pivoted to the bracket member generally at the juncture of the bight portion 34a and the leg portion 34b. As best seen in FIG. 1, the leg portion 340 of the latch member terminates in a downwardly extending stop tongue 34d. To mount the track 12 onto the brackets 32, the offset projection 32d on the end of the horizontal portion 32b of each bracket 32 first is positioned within the groove 40a at the front of the track beneath the flange 38a, with the latch member 34 pivoted to the position shown in FIG. 10 so that the leg portion 34d bypasses the flange 38b to a position between the flanges 38a, 38b in line with the groove 40b. The latch member 34 then is pivoted to the position shown in FIG. 11 whereby the leg portion 34b seats within the groove 40b on the underside of the flange 38b to lock the track 12 to the bracket 32 as the stop tongue 34d abuts against the backside of the track.
FIG. 4 shows a section through a carrier member 24 (FIG. 2) with the enlarged head portion 28 on top of the neck portion 26 of a folding plate 10 seated within the recess 24a of the carrier member. As seen best in FIG. 2, the carrier members 24 are generally U-shaped and have horizontal slots 44 which receive the flanges 22 (FIG. 3) to mount the carrier members on the track 12 whereby the carrier members ride along the flanges 22 as the drapery is folded and unfolded. An upstanding flange 46 is formed on opposite sides of the elongated slots 24b at the mouth 48 leading to the recess 24a. As best seen in FIG. 4, the top of the flanges 46 have surfaces 50 inclined upwardly and inwardly toward the recess 24a to guide the head portion 28 of a folding plate 10 into the recess. The flanges 46 prevent the head portions 28 from jumping out of the recesses accidentally as the folding plates and carrier members are moved along the track. By inclining the top of the flanges 46, sufficient space is provided to pennit the head portions to clear the front lower edge of the track 12 and enter the recess. The head is inserted into the recess by tilting plate 10 so that the head portion is generally parallel to the inclined surface.
Referring to FIGS. 2, 5 and 6, the master carrier members 30 are somewhat similarly mounted on the underside of the track 12 for movement therealong to carry an end folding plate 10a, as best seen in FIGS. 1 and 2. Referring to FIG. 6, the master carrier members 30 have an interior recess 52 for receiving the head portion 28 on the top of a neck portion 26 extending upwardly from the top of the end folding plate 100. As with the carrier members 24, the master carrier members have a flange 54 extending upwardly into the mouth 48 of the recess 52 on opposite sides of a'downwardly opening slot 56 to prevent the head portion 28 from jumping out of the recess 52. The flanges 54 also have inclined upper surfaces 54a for purposes described above with relation to the carrier members 24. The master carrier members have a slot 58 for receiving one of the flanges 22 of the track 12 for movement therealong. The rear of the master carrier members has an inwardly offset, upwardly extending plate portion 60 which seats behind a downwardly extending flange 62 of the track 12, with the lower end of the plates 60 terminating in a shoulder 64 which seats on top of an inwardly extending flange 66 of the track to guide the master carrier members along the track structure. As best seen in FIGS. 2 and 5, the upwardly extending plate portion 60 .of the master carrier members 30 has keyhole type apertures 68 for receiving an operating cord 70 in a conventional manner so that the master carrier members are pulled back and forth along the track 12 when an operator pulls on one or the other runs of the operating cord in a conventional manner. As best seen in FIGS. 5 and 6, a rib 69 is formed on the master carrier members 30 integral with the plate portion 60. This rib performs two functions. First, it rigidities the plate portion 60 to prevent shrinkage or deformation of the plate portion. Second, it spaces the cord 70 outwardly from the plate portion, as best seen in FIG. 6, for easy gripping to loosen the cord, for instance for adjustment purposes. For purposes to be described in greater detail hereinafter, and referring particularly to FIG. 6, the downwardly opening slot 56 for receiving the neck portion 26 on the top of the innermost (relative to the track) end folding plate a is elongated to permit the neck portion 26 and thus the end folding plate 100 to move relative to the master carrier members 30, perpendicular to the track 12 during movement of the master carrier members along the track to fold and unfold the drapery.
End pieces 76, to be described in greater detail hereinafter, are provided at the ends of the track l2, and each end piece has a portion, generally designated 76a in FIG. 3, depending from the underside thereof and shaped similar to the underside of the master carrier members. More particularly, as with the carrier members 24 and master carrier members 30, each end piece portion 76a has an interior recess 76b for receiving the head portion 28 on top of the neck portion 26 extending upwardly from an end folding plate 10b (FIG. 1). Flanges 76c extend upwardly into the mouth of the recess on opposite sides of a downwardly opening slot 76d to prevent the head portion of the end folding plate 10b from jumping out of the recess 76b. As with the master carrier members 30, the slots 76d are elongated to permit the outermost end folding plates 10b to move relative to the end pieces 76 when the drapery is folded and unfolded, for purposes described hereinafter.
Before going into the function of the elongated slots 56 and 76d in the end carrier members and end pieces, reference first should be made to FIGS. 7-9 which show the structure and arrangement for moving the master carrier members by means of the operating cord 70. Referring first to FIG. 3, it can be seen that the operating cord 70 has a pair of oppositely movable runs, as is conventional, with the cords hanging freely over a control pulley, generally designated 72, shown at the right-hand end of the track 12 in FIG. 3. At the opposite end of the track, the cord passes around a return pulley 74. The cord extends generally from end to end of the elongated track 12 and is disposed within a hollow channel 75 of the track. The cord may be of the continuous loop type. In the embodiment of the invention shown in FIG. 3, the pulleys 72 and 74 are mounted on the end pieces 76 which fit into the end of the track 12. The end pieces 76 have channel shaped portions 76a which are inserted into the track 12 in a hollow space defined by the top of the track and a pair of flanges 78 on which the channel-shaped portions 76a of the end pieces seat. The end pieces 76 are held in position within the end of the track 12 by means of tapping screws 80 screwed into threaded bosses 82 on the inside of the channel shaped portions 76a of the end pieces 76. Washers 84 are positioned between the heads of the tapping screws and the flanges 78. Once the end pieces 76 are positioned at the ends of the track 12, both the control pulley 72 and the return pulley 74 are concealed within the hollow space of the channel 76 of the track 12 through which the runs of the cord extend.
The various views of the control pulley 72 in FIGS. 7-9 show that the control pulley has a generally horizontal shaft 81 extending generally perpendicular to the track 12. Vertical slot means 82 (FIGS. 3 and 8) are provided for receiving the ends of the shaft 81. The slots 82 are slightly smaller than the diameter of the shaft 81 at the entrance of the slots, with the base 82a of the slots being enlarged, so that the control pulley can be snapped into the slots and seated in the base portion 82a thereof for free rotation, and with the shaft 81 prevented from jumping out of the slots during movement of the operating cord 7, as best seen in FIG. 8. The control pulley 72 comprises a pair of pulley members 72a which are joumaled on the shaft for rotation relative thereto. The pulley shaft 81 is positioned axially relative to its respective end piece 16 by an annular, triangularly shaped rib 81a (FIGS. 7 and 9) which is received in a complementarily shaped groove 83 formed in an upstanding rib 83a of the end piece between the pulley members 72a. As seen in FIG. 9, the pulley shaft 81 has shoulders 81b for axially positioning the pulley members 72a and preventing the pulley members from rubbing against the rib 83a of the end piece.
As stated above, the downwardly opening slots 56 of the end carrier members are elongated in a direction perpendicular to the track 12 to permit the end folding plates 10a to move fore and aft during folding and unfolding of the drapery. This is important to prevent binding of the end plates as they are pulled by the operating cord 70, primarily during the initial unfolding of the drapery and at the extreme unfolded position of the drapery. FIGS. 13 through 16 show positions of an innermost (relative to the ends of the track) end folding plate 10a and intennediate folding plates 10 during various sequential positions of unfolding of a drapery. FIG. 13 shows the end and intermediate folding plates in their respective positions when the drapery is completely folded. As the drapery initially is unfolded, the master carrier member 30, through the cord 70, pulls the end folding plate 10a (see FIG. 14) away from the intermediate folding plates 10 toward the opposite end of the track. When this is done, the innermost end folding plate 10a has a tendency to pivot in the direction of arrow A (FIG. 14) which, without limited fore and aft movement of said end plate, would tend to cause binding of the master carrier member because of the tendency to twist relative to the elongated track 12. By providing the elongated slot 56 in the master carrier member, the innermost end folding plate 10a is permitted to move slightly away from the center line 83 of the remaining folding plates, as shown in FIG. 14. As the unfolding of the plates continues, and the succeeding intermediate folding plates 10 are unfolded, as shown in FIG. 15, the innermost end folding plate a moves back in line with the remaining folding plates 10 until the folding plate 10a reaches its limit of travel and all of the folding plates are in their fully extended unfolded position. When the plates are completely unfolded, as shown in FIG. 16, the end plate 10a which is being pulled by the cord 70 again has the tendency to move perpendicular to the track 12 to the opposite side of the center line 83 of the remaining folding plates 10, again with a tendency to bind. By providing the elongated slot 56 in the master carriers 30, the end folding plate 10a is permitted to move slightly in a fore and aft direction to the position shown in FIG. 16 wherein all of the folding plates are in their fully extended position. FIGS. 17 and 18 show that the outennost end folding plate 10b (to the right in FIGS. 17 and 18) also has a tendency to move perpendicular to the track as the plates approach and reach their fully unfolded position. Arrow C in FIG. 17 illustrates that as the folding plate 10 immediately adjacent the outermost end plate 10b begins to pull on said end plate, it tends to pull the end plate 10b to one side of the center line 83. As the folding plates reach their completely unfolded position, the forces are such that said adjacent end folding plate 10 (as best seen in FIG. 18) tends to kick the outermost end plate 1012 back toward the opposite side of the center line 83 in a pivoting direction indicated by arrow D. Thus, as with the innermost end plate 10a which is pulled by the master carrier member 30, the outermost end plate 10b has limited movement in a direction perpendicular to the track 12 as is provided by the elongated slots 76d in the end pieces 76. Furthermore, as pointed out above, the slots 24b of the carrier members 24 also are slightly elongated, as best seen in FIG. 38, to permit limited fore and aft movement of the intermediate folding plates 10 in a direction perpendicular to the track 12. As with the master carrier members 30 and the end pieces 76, this prevents possible binding of the intermediate folding plates 10 as they move back and forth during opening and closing of the drapery.
As best seen in FIGS. 19 and 20, the stop surfaces 20 may be formed at different angles to provide different angles of fold for the folding plates 10 and thus provide for different shaped pleats in the supported drapery. The angle of fold is dependent upon the angle formed between the stop surfaces 20 and the elongated center section 16 of the folding plates. The greater the angle between the stop surfaces and the center section 16 of the folding plates, the greater is the angle of fold. The angle between the stop surfaces 20 in FIG. 20 and the center section 16 of the folding plates is less than the corresponding angles in the folding plates illustrated in FIG. 19 and, thus, lesser angles of fold are provided. Since the ends of the folding plates have complementary hinge structures, as described above, folding plates such as those shown in FIGS. 19 and 20 may be mixed so as to provide varied angles of folds along the track 12 and therefore variedshaped pleats along a single drapery panel supported by the track.
As stated above, the folding plates shown in FIGS. 1 and 2 are provided with slots 14 on both vertical faces of the plates. This is provided to make it possible for draperies to be attached on both sides of the plates to form an area divider, for example, or to suspend a drapery lining from the slots on one side of the folding plates, with the drapery panel being suspended from the opposite side of the plates. FIG. 21 shows a vertical cross sectional view through a modified form of folding plate wherein a pair of dovetail slots 84a, 84b are formed on the same side of a folding plate 10 to accommodate a drapery and a drapery liner, for instance, on the same side of the plate. The slots 84a, 8411 are vertically spaced, with the lower slot 84b being offset inwardly of the slot 84a so that two panels may be hung on the same side of the plate, the outside panel being attached to the plate in slot 840 and the inside panel (e.g., a drapery liner) attached to the plate in the slot 84b In US. Pat. No. 3,296,651, the drapery attaching means or sliders are shown in the form of a fabric strip sewn to the top of a drapery panel, with a plurality of male portions of a standard snap fastener providing the means for snapping the drapery panel into the dovetail slots of the folding plates. The male portions of the snap fastener strip simply are snapped into the slots of the folding plates and slidable therealong to a proper position to form the desired pleats which follow the contour of the folds of the folding plates. FIGS. 22, 23 and 34 herein show an attaching means which comprises a flexible extruded, preferably plastic, strip having a generally flat base portion 86 for attachment to a drapery panel and a bead-like, elongate upstanding male portion 88 for snapping into the slots 14 on the drapery folding plates 10. The flat base portion 86 is sufficiently thin so as to permit the strip to be sewn directly to the drapery panel. The form of the strip shown in FIG. 23 includes a slot 90 extending lengthwise of the elongate upstanding portion 88 to enhance the resiliency thereof for snapping into the slots 14 of the folding plates. FIG. 34 shows a cross sectional view through the center section 16 of a folding plate 10 with the attaching strip of FIG. 22 snapped within one of the slots 14 of the folding plate.
FIG. 35 shows a modified form of attaching strip or slider similar to that shown in FIGS. 22 and 34, but designed to support a relatively heavy drapery panel, such as one made of velvet or the like. In this embodiment, the bead-like male portion of the attaching strip has a generally straight surface portion 92 mating generally with the upper flat side 94 of the dovetail slot 14 to strengthen the connection between the slot and the slider. The opposite side of the bead-like male portion is rounded as at 96 whereby the straight surface portion 92 may be prepositioned within the slot and the rounded side 96 then may be forced into the slot to snap the slider into the slot. Although a substantial portion of the weight of the drapery panel generally will be in the direction of arrow E in FIG. 35, there is a tendency for the slider type attaching means to pivot in the direction of arrow F. By providing the straight surface portion 92 on the slider, there is a lesser tendency with heavy drapery panels for the slider to pop out of the slot 14 in the folding plates than with the embodiment shown in FIG. 34.
FIG. 36 shows another form of the attaching means or slider wherein means is included to provide a frictional drag between the sliders and the folding plates to limit longitudinal movement of the sliders within the tom of the slot 14 to provide a frictional drag for the slider.
As shown in my US Pat. No. 3,296,651 and in FIGS. 1 and 2 herein, the complementary offset end sections 18 and 19 form a generally cylindrically shaped hinge and, when hinged together end to end, at least one offset hinge section (i.e., 18) has an outer rounded portion 100 (FIG. 2) which forms the outer extremity of the hinge. In certain instances, it may be desirous to permit the flexible elongated sliders, such as those shown in FIGS. 22, 23 and 34-36, to pass about the outer periphery of the hinges. FIG. 24 shows a modified form of hinge wherein a cutaway portion 102 is provided so as to permit the elongated sliders to be positioned about and to move about the hinge connections between adjacent folding plates.
FIG. 37 shows a further modification of the folding plates wherein a raised, inclined rib or ramp 103 is formed at the ends of the slots 14 which receive the sliders attached to the drapery panel. These ribs or ramps prevent the sliders from accidentally pulling out of the ends of the slots 14 during movement of the drapery panel. In the preferred embodiment, the ribs or ramps 103 do not block the ends of the slots completely so that the sliders may be forced out of the ends of the slots to remove the drapery panel from the folding plates. The ribs are inclined to provide a cam surface to facilitate forcing the sliders thereover.
FIGS. 25 and 26 show a spring means to establish uniform folds between the folding plates along the entire length of the track 12 so as to form uniform pleats in the drapery panel. In the embodiment shown in FIGS. 25 and 26, the spring means comprises a generally flat resilient strip 104 fabricated of plastic or like material which is bent and nested into the hinged joints of adjacent folding plates as best seen in FIG. 25. A male slider portion 104a is disposed at each end of the flat, strip for snapping into the slots 14 of the folding plates. The strip 104 is sufficiently thin to permit the strips to be sewn directly onto a drapery panel, not only to provide the spring for the hinge joints but also to comprise the means to attach the drapery to the folding plates. Stops 106 (FIG. 25) are formed on the folding plates within the slots 14 to prevent the spring strips 104 from sliding away from the hinge joints of the folding plates. FIG. 27 shows another form of such means wherein a resilient wire-like member 108 is sandwiched between the drapery panel D and the attaching strip 110 of a standard snap fastener strip which is sewn directly to the drapery panel. FIG. 28 shows a further modified form of the invention wherein a resilient wirelike member 112 is embedded within the bead-like male portion of the extruded fastener strip shown in FIG. 22 to add resiliency to the strip, particularly when the strip is nested within the hinges of the folding plates.
FIGS. 29 and 30 show modified end pieces 76' for the track in which the pulleys are interchangeable, enabling selection of the end at which the operating portion of the cord is located without disassembly of the track. The structure shown in said figures is similar to that shown in FIG. 3 in that the end pieces 76 are provided for insertion into the end of the track 12 and held therein by tapping screws 80. Like numerals will be applied where applicable and elements which are modified are given like numerals with a prime mark. As with the structure shown in FIG. 3, a control pulley 72' and a return pulley 74' are provided, with one end of the loop of the cord passed around the return pulley mounted on one of the end pieces 76' at one end of the track and the other end of the loop of the cord hanging freely from the other end of the track after passing over the control pulley 72, for access to operate the cord to move the drapery. Each end piece 76' has a saddle formed by slots or notches 116 and a groove 83, to be described in greater detail hereinafter, for receiving the control pulley 72' with a control pulley shaft 81' received in the notches 116 generally on a horizontal axis. As with the structure shown in FIGS. 7 and 9, the control pulley 72 comprises a pair of pulley members 72a which are journaled on shaft 81 for rotation relative thereto. The pulley shaft 81' is positioned axially relative to the end pieces 76' by an annular, triangularly shaped rib 81a which is received in a complementarily shaped groove 83' formed on an upstanding rib 83a of the end pieces between the pulley members 72a. As seen in FIG. 30, the pulley shaft 81' has shoulders 81b for axially positioning the pulley members and preventing the pulley members from rubbing against the rib 83a of the end pieces. In front of or inwardly of the rib 83a is a shaft stub 118 extending up wardly from a flat base portion 119 of the end piece 76 and over which is received the return pulley 74'. An aperture 120 is formed in the flat base portion 119 substantially around rib 83a and beneath the saddle formed by the notches 116 and groove 83 through which the free operating end of the loop of the cord may extend for access to operate the cord to move the master carrier 30 to fold and unfold the drapery folding plates. A reinforcing rib 121 is provided spanning the outside notch 116 to provide support for the flat base portion 119. In order to interchange the end of the track from which the accessible looped portion of the cord extends, the screws first are loosened so that the end pieces 76 may be moved out of the end of the track 12 to expose the pulleys. The cord 70' then is loosened and the control pulley 72 is lifted out of the saddle formed by the notches 116 and groove 83'. The control pulley then is moved to the opposite end of the track and positioned in the saddle formed in the opposite end piece 76'. Similarly, the return pulley 74 is lifted off of the shaft stub 118 on the left-hand end piece, as viewed in FIG. 29, and is positioned on the shaft stub 118 on the opposite or right-hand end piece 76 at the opposite end of the track. The closed loop of the cord (at the left-hand end in FIG. 29) then is pulled through the aperture 120 in the left end piece until the opposite end loop of the cord is pulled upwardly and wrapped around the return pulley now positioned on the right end piece 76, as viewed in FIG. 29. Now, the looped cord hangs freely from the left end piece at the opposite end of the track from its orientation shown in FIG. 29.
Not only does the structure shown in FIGS. 29 and 30 permit selection of the end of the track at which the operating portion of the cord is located without disassembly of the track, but, with further reference to FIG. 47, the structure described above permits the utilization of a plurality of operating cords 70 for independently shifting drapery panels along the track. More particularly, as schematically shown in FIG. 47, a control pulley, generally designated 72' and a return pulley 74 both may be disposed in operating position within each end of the track, one each on each of the end
