16 Claims. (Cl. 160-344) The present invention relates to a drapery tixture. More particularly, the present invention relates to a master slide construction for draperies which is adapted to prevent the draperies from parting after they have been drawn to the closed position.
In drapery assemblies which include the conventional master carrier construction, wherein the operating cords are secured directly to the master carrier, it is frequently diicult to bring the drapery meeting ends together by operation of the operating cords since stresses set up in the operating cords tend to separate the meeting ends when the tension in the cords is relieved. Generally, the heretofore known master carriers are formed with overlappings extensions which are designed to bring the draperies to the closed position in overlapping relation. However, when the operating cords are stretched during the closing operation, relieving the tension therein will tend to slightly part the draperies, which parting is both unsightly and annoying and usually requires an additional manual movement to close.
It is therefore an object of the present invention to provide a master carrier construction for draperies wherein undesirable parting is prevented when the draperies are moved to a closed position.
Another object of the present invention is to provide a master carrier construction for draperies wherein tension in the operating cords is automatically relieved when the draperies are moved to the closed position.
Still another object of the present invention is to provide a master carrier construction for draperies which includes a primary slide and a secondary slide, the secondary slide being adapted to move relatively to the primary slide to relieve tension in the operating cord.
Still another object of the present invention is to provide a drapery xture wherein a lost motion device associated with the master carriers is adapted to prevent drapery parting in the closed position.
Still another object of the present invention is to provide a drapery xture wherein the drapery operating cord is secured to a secondary slide, the secondary slide being adapted to move relatively to a primary slide, thereby relieving tension in the operating cord when the draperies are moved to a drawn position.
Other objects and the nature and advantages of the instant invention will be apparent from the following description taken in conjunction with the accompanying drawings, wherein:
Fig. l is a rear view in perspective of one form of the drapery fixture embodied herein, showing the master carriers in the closed position;
Fig. 2 is an enlarged vertical sectional view of the drapery xture illustrated in Fig. l as seen from the front;
Fig. 3 is a perspective view of the master carrier construction shoWn in Figs. l and 2;
Fig. 4 is a sectional view taken along the line 4 4 in Fig. 2;
Fig. 5 is a perspective view of a modified form of thi master carrier construction; and
Fig. 6 is a perspective view of a further modified torn of the master carrier construction.
Referring now to the drawings, and particularly Figs l-4, one form of the present invention is illustrated an( includes a traverse rod 10 formed in a generally C con figuration, one wall of the traverse rod defining a track way for slidably receiving a plurality of drapery slide` 12 and master carriers' generally indicated at 14 and 16 Secured to the extreme4 ends of the traverse rod 10 whicl may be of the telescoping type are end brackets 18 an( 20, the end brackets 18 and 20 being fastened to a x ture above the window or door to be draped in an] convenient manner. Rotatably mounted in the end brack ets 18, 20 are pulleys 22, 24 (Fig. 2) which are adapte: to receive an operating cord 26 thereon, the free end; 28, 30 of the operating cord 26 depending from oni set of pulleys as shown in Figs. l and 2. It is understoo( that if it is desired, the operating cord 26 may be s( arranged that the free ends 28, 30 thereof depend fron the opposite end bracket as that illustrated. The draperj slides 12 and the master carriers 14, 16 are adapted t( receive drapery hooks in the conventional manner, thi drapery hooks being attached to the upper end portion` of drapery sections indicated at 32 and 34 in the con ventional manner, The operating cord 26 is secured t the master carriers 14 and 16 as will be described here inbelow, and it is seen, therefore, that upon pulling o either end 2S or 30 of the operating cord 26, the maste carriers 14 and 16 will be caused to move along thi traverse rod 10, thereby moving the slides 12 and th associated draperies 32, 34 therewith.
Referring now to Fig. 3, the master carriers 14 an( 16 are more clearly illustrated and as shown are forme( in substantially the same manner. Master carrier 1 includes a primary slide generally indicated at 36 tha comprises a longitudinally extending bar 37 that ha` an offset portion 38 formed integral therewith, the olf set portion 38 providing for overlapping with a simila b ar formed on the master carrier 16. As described here inabove, the bar 37 has convenient openings 40 (Fig 2) formed therein for receiving the drapery hooks at tached to the drapery sections 32, 34. Formed integra with the bar 37 are vertical plates 42 and 44, the plat 42 having a stop 46 formed thereon and the plate 4 having a similar stop 48 formed thereon. Secured tt the plates 42 and 44, respectively, are guides 5l) an( 52, the Uuides 50, 52 being formed in a T configuratiol and being received in the trackway defined by the opel side of the traverse rod 10, thereby mounting the primari slide 36 for free movement on the traverse rod 10. A illustrated and described, the primary slide 36 is not se cured to the operating cord 26 in any manner and i` free to move relative thereto within a limited space, a` will be described hereinafter. Slidably mounted on thi traverse rod 19 is a secondary slide 54 which comprise a block secured to a guide 56, the guide 56 being mounte( for slidable movement in the traverse rod trackway One length of the operating cord 26 extends through z projection 57 (Fig. 2) formed on the guide 56 and i` secured therein, thereby securing the secondary slide 5f for movement with the operating cord 26. As show! in Fig. 3, the secondary slide 54 is positioned in abutting relation against the stop 48 of the primary slide 36 an( thus will move the primary slide in an inwardly direc tion in response to movement of the operating cord. Simi larly, the secondary slide S4 is adapted to be moved int( abutting relation with the stop 46 of the primary slidi '36 and continued movement of the secondary slide 54 i1 an outwardly direction will force the primary slide 31 therewith.
The master carrier 16 includes a similar assembly of lements as described above in connection with master arrier 14 and comprises a primary slide generally indiated at 58 and a secondary slide 60. The primary slide 8 includes a longitudinally extending bar 62 having ook openings 63 (Fig. 2) formed therein and spaced ertical plates 64, 66 having stop 68, 70, respectively, Jrmed integral therewith. The primary slide 58 is idably mounted on the traverse rod l by means of uides 72, 74 secured to the plates 64, 66, respectively. he secondary slide 60 is slidably mounted on the traverse :ad 10 by a guide 76 secured thereto, the'operating cord 6 extending through a projection 78 (Fig. 2) formed n the guide 76 and secured therein, the secondary slide 0 thereby being responsive to movement of the operatlg cord. As described above in connection with master ,ide 14, the secondary slide 60 is freely movable within 1e space defined by the stops 68, 70 and is adapted to ontact the stops 68, 70 for moving the primary slide 8 in a desired direction.
In operation, when it is desired to draw the draperies 2, 34 to a closed position, the operating end 28 of the pel-ating cord 26 is pulled. The secondary slides 54 nd 60 secured to the operating cord 26 are moved into ontact with the stops 48 and 70, respectively, and the rimary slides 36 and 58 are thus drawn to the closed osition carrying the associated draperies 32 and 34 lerewith. When the primary slides 36 and 58 reach 1e closed position, the weight of the draperies has caused 1e cord 26 to be stretched in tension and a sudden re- :ase of the cord would normally cause the master carers to part. However, since only the secondary slides 4 and 60 are secured to the operating cord, there is a ist motion effect and the secondary slides are permitted )move relatively to the primary slides 36 and 58 Within 1e space defined by the stops 46, 48 and 68, 70. Thus, 1e primary slides remain stationary upon relaxation of 1e operating cord 26 and their associated draperies will e prevented from parting. If it is desired to part the raperies, the operating end 30 of the cord 26 is pulled nd the secondary slides will then be moved into contact 'ith the stops 46 and 68, respectively. Continued movelent of the secondary slides 54 and 60 in an outwardly rection will pull the primary slides 36 and 58 and the ssociated draperies 32 and 34 to the open position.
Referring now to Fig. 5, a modified form of the inention is illustrated and includes master carriers genfally indicated at 80 and 82. The master carrier 80 Jmprises a primary slide 84 which includes a vertical late 86 formed with an oset horizontal bar 88, the tfset horizontal bar 88 being formed with appropriate penings for receiving draper hooks. Secured to the late 86 of the primary slide 84 are guides 90, 92 which re slidably mounted in a trackway of a traverse rod not shown), thereby mounting the primary slide 84 )r free movement on the traverse rod. Formed in the ertical plate 86 is a horizontally extending slot 94 which :ceives a pin 96 for slidable movement therein. The ln 96 is secured to a secondary slide which in this modi- :ation comprises a guide 98, the guide 98 being in turn :cured to one length of an operating cord 100. It is :en that movement of the secondary slide or guide 98 ill, in turn, move the primary slide 84. The master lrrier 82 is constructed similarly to the master carrier l and includes a primary slide 102 comprising a plate )4 to which a bar 106 is integrally joined, the bar 106 :ing formed with appropriate openings for receiving apery hooks therein. Secured to the plate 104 are lides 108 and 110 for slidably mounting the primary ide 102 on the traverse rod (not shown) and a slot l2 is formed in the plate 104, the slot 112 being adapted slidably receive a pin 114. The pin 114 is secured to secondary slide or guide 116 which is in turn secured a length of the operating cord 100.
In operation, the draperies associated with the master carriers and 82 are drawn to a closed position by pulling the appropriate end of the operating cord. The secondary slides 98 and' 116 secured to the operating cord are caused to move therewith, thereby moving the pins 96 and 114 to the inner end of the slots 94 and 112, respectively. Continued pulling of the operating cord then moves the primary slides to the drawn position. When the cord 100, which has been under tension during the drapery drawing operation, is released, the secondary slides 98 and 116 tend to move outwardly with the cord and a lost motion effect results as the secondary slides 98, 116 move relatively to the primary slides 84, 102. Since the secondary slides 98, 116 and the associated pins 96 and 114 move in the slots 94 and 112, the primary slides 84 and 102 will remain stationary and the ends of the drawn draperies will therefore be prevented from parting.
Referring to Fig. 6, a further modified form of the master carriers is illustrated and includes master carriers generally indicated at 118 and 120. The master carrier 118 includes a plate-like secondary slide 122 which has openings 124 formed adjacent the lower end thereof for receiving drapery hooks therein. Secured to the secondary slide 122 are guides 126, 128 which are slidably mounted in a trackway of a traverse rod (not shown), thereby mounting the secondary slide 122 for free movement on the traverse rod. In this modification, an operating cord is adapted to be secured to the secondary slide 118 and, for this purpose, the secondary slide 118 is formed with slots 132, 134 in the body thereof. A projection 136 is also struck out from the secondary slide body and as shown the cord 130 extends into the slots 132, 134 and through the opening defined by the projection 136, the cord 130 thereby being securely fixed to the secondary slide 122. Secured to the secondary slide 122 adjacent the inner end thereof is a pin 138 which is adapted to be received in a slot 140 formed in a primary slide 142. The primary slide 142 is secured to a guide 144 which is slidably mounted in the trackway of the traverse rod (not shown), thereby mounting the secondary slide for movement on the traverse rod. The primary slide 142 v is formed in an inverted L configuration,` the lower extension thereof being formed with an opening. 146 for receiving a drapery hook. It is seen that movement of the secondary slide 122 Will, in turn, move the primary slide 142 by means of the pin and slot construction, thereby moving the associated drapery to the. desired position. In the modified master carrier detail illustrated in Fig. 6, the drapery hook located at the innermost end of the associated drapery is adapted to be inserted into the opening 146 formed in the primary slide 142 and since the primary slide is not connected to the operating cord 130, it is seen that the drapery end will remain stationary when the secondary slide 122 moves relatively to the primary slide 142 and Within the limits defined by the slot 140.
The master carrier 120 is constructed similarly to the master carrier 118 and includes a plate-like secondary slide 148 in which openings 150 are formed for receiving drapery hooks. Secured to the secondary slide 148 are guides 152, 154 which are slidably mounted in the trackway of the traverse rod (not shown) and formed in the secondary slide along the upper edges thereof are slots 156, 158 which receive the operating cord 130 therein. A projection 160 is struck outwardly from the body of the secondary slide 148 between the slots 156, 158 and defines an opening for receiving the operating cord 130 therein, the secondary slide 148 thereby being locked to the operating cord and responsive to the movement thereof. Operatively secured to the secondary slide 148 is a primary slide 162 which is formed With a slot 164, the slot 164 receiving a pin 166 secured to the secondary slide 148. The primary slide 162 is formed With an offset extension 168 that is adapted to overlap with the extension formed on the primary slide 142 the extension 168 having an opening 170 formed therein for receiving the innermost hook of the associated drapery. Secured to the primary slide 162 is a guide 172 that slidably mounts the primary slide on the traverse rod.
In operation, the appropriate end of the operating cord 130 is pulled to draw the secondary slides 122, 148 toward the center of the traverse rod, thereby drawing the associated draperies together. of the draperies is reached and the operating cord is released, thereby relieving the tension therein, the secondary carriers 122, 148 tend to move outwardly. However, due to the pin and slot construction, a lost-motion is effected between the primary and secondary slides, the primary slides 142, 162 remaining stationary. Since the innermost end of the draperies is attached to the stationary primary slides, the drapery ends will then be prevented from parting.
It is seen that in all forms of the present invention, there is movement of the secondary slide relative to the primary slide when the operating cord is relaxed after the draperies have been drawn to a closed position. The master carrier construction described herein may be applied with any existing traverse rod fixture and is generally applicable with all types of drapery fixtures. The master carrier structure is simple, easy to manufacture, and economical in operation, requiring little or no maintenance.
It will be obvious to those skilled in the art that various 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.
