- 3 The arms 12 are substantially parallel from the sections 19 to the loops 13.

The drapery supporting member should be formed in such a manner that the arms 12 at the contiguous section 18 are tensioned toward one another to reduce the space between the two arms 12 in this contiguous Section to a distance apart less than the diameter of the wire forming the hook element 11, and preferably into touching relationship. The hook element 11 is formed with a leg 20, bight 21 and leg 22 continuous with one another. The leg 20, which may also be termed a shank, is formed with a crimp 23 at its lower portion with the crimp 23 preferably in the same plane as legs 20, 22 and bight 21.

The plane of the arms 12 in the drapery supporting member 10 and the plane of the hook element 11 are normal to one another. The hook element 11and drapery supporting member 10 are interengaged by the interlock of the crimp 23 with the pinch 15. The crimp 23 is positioned on one side of the pinch 15 with the lower portion of the leg 20 projecting throughthe opening 16 and extending downwardly of the supporting member 10 on the other side of the bight section 14 as indicated at 28, FIG. 2. The upper portion 26 of the leg 20 projects through the loop 17 and bears against the contiguous section 18 as indicated at 29. The upper portion 26 of the leg 20 may, if desired, be slightly inclined towards the drapery supporting member 10 and between the arms 12 above the contiguous section 18 to effect a more positive engagement between the upper portion 26 and the contiguous section 18. Preferably, the upper portion 26 bears directly against both legs 12 at the contiguous section 18.

The bight 21 is inclined upwardly from the leg 20. A crimp 30 is formed at the upper end of the bight 21 with this crimp 30 having sides 31 and 32. The rear side 32 extends downwardly and is contiguous with the leg 22. Crimp 30 is adapted to engage a slider of conventional shape and size. These sliders are supported on traverse rods and are adapted to be moved longitudinally of the rod for the purpose of carrying the drapes and drapery hooks.

The sides 31 and 32 engage the forward and rear portion of the slider respectively as indicated in my copending application Serial No. 788,699. It has been found that locating the crimp 30 at the rear end of the bight 21 and inclining the bight is substantially advantageous over the construction shown in my copending application. Such an arrangement causes the drapes to hang straighter and permits shading of the sliders without binding of the hooks against the traverse rod.

This embodiment may be assembled by first inserting the lower portion 25 of the leg 20 through the loop 16 so that hook element 11 assumes the position illustrated at 35 in dotted outline. The hook element 11 is then rotated counterclockwise relative to the dnapery supporting member 10 to the position of final assembly. Hook element 11 is maintained in locked position to the relative drapery supporting member 10 when the upper portion 26 of the shank or leg 20 is passed between the contiguous sections 18. As the hook element 11 is moved between the legs 12 it forces contiguous sections 18 apart. Once the hook element 11 is in the position indicated in solid line in FIG. 2 the contiguous sections 18 spring together again thereby locking the hook element 11 in place.

The simplicity of this assembly eliminates the necessity of welding and expensive machinery and equipment for assembling the hook element and drapery supporting member, as is necessary with other types of constructions. Moreover, it permits assembly by the ultimate consumer, and thereby eliminates expensive manufacturing costs. When a drape is inserted on the arms 12, the drapery pocket is forced between the contiguous section 18 and the upper portion 26 of the leg 20, which further assures a rigid interlocking arrangement between the member 10 and element 11. Since the leverage distance .4 between the bight 14 and the pinch 15 is short, a substantial torque on the hook element 11 relative to the drapery supporting member 10 is possible without the crimp passing between the arms at the pinch 15. It has been found that the wire of the hook element 11 will bend before the wire at the pinch 15 of the drapery supporting member 10 will spread.

In the embodiments illustrated in FIGS. 3 and 4, like numerals refer to the corresponding elements illustrated in the embodiment shown in FIGS. 1 and 2. The shank or leg 20 is longer and is provided with a pair of crimps 23 and 40. The crimp 40 may engage pinch 15 in a manner similar to the interengagement of the crimp 23 and pinch 15. When the crimp 40 is interengaged with the pinch 15, the crimp 23 is positioned between the arms 12 close to their upper end. In this position drapery material supported on the arms 12 will be reversely folded about crimp 23 and will thereby be more rigidly clamped.

When the crimp 23 is interengaged with the pinch 15, drapes will be supported higher than when crimp 40 is interengaged with the pinch 15. If desired, more than two crimps may be incorporated into the leg 20 so that more than two positions of adjustment are possible. The crimps should be spaced apart a distance greater than the distance between the pinch 15 and upper end of the contiguous section 18 so as not to interfere with the interlock of the two members.

The embodiment of the invention illustrated in FIGS. 5 and 6 is similar to the embodiment illustrated in FIGS. 3 and 4 where like numerals refer to similar parts. In this arrangement the hook element 50 is formed with a bight 51, rear leg portion 52 and shank 53. This hook element 50 is not provided with a crimp arrangement illustrated at 30 in FIGS. 1-4 although if desired, it could be. The shank 53 is formed with a pair of crimps 23 and 40 similar to those previously described in connection with the embodiment of FIGS. 3 and 4. The lower end of shank 53 is bent into a loop 54 having an opening 55 through which the bight portion 14 of the drapery supporting member 10 may be inserted. This loop 54 acts as a pivot in assembling the hook element 50 and drapery supporting member 10. The loop 54 permits the hook element 50 to be pivoted from a position illustrated in dotted outline at 56 to the position indicated in solid outline (FIG. 6). In the assembled arrangement the crimp 40 interengages the pinch 15 while an intermediate portion of the leg 20 indicated at 57 engages the contiguous section 18. The crimp 23 projects between the legs 12 just above the contiguous section 18 thereby forming a positive clamping arrangement for securing drapes therebetween. If desired, the crimp 23 may be interengaged with the pinch 15 in a manner as indicated previously so that the drapes may be supported in a relatively higher position. The rounded loop 54 prevents the lower end of the shank 53 from catching or tearing the drapery material.

In the arrangement illustrated in FIGS. 7 and 8 there is provided an adjustable hook utilizing three interengaging members. These include hook element 60, drapery supporting member 61 and an interlocking member 62. The drapery supporting member 61 is formed with parallel arms 63 terminating at their upper end at loops 64 similar to loop 13 in FIG. 1. The arms 63 are interconnected at their lower end in a bight section 65. The lower ends of the arms 63 immediately adjacent to the bight 65 are inclined toward one another into touching relation forming a pinch 66. An opening 67 is formed between the pinch 66 and bight 65. Immediately above the pinch 66 is a loop 68 formed by an enlargement of the arms 63. The arms 63 between the upper end of the loops 68 and the loops 64 are parallel to one another and are either closely spaced, or in touching relation along their length. As best illustrated in FIG. 8, the drapery supporting member 61 is slightly curved at its lower end from the pinch 66 to the bight 65. This curve angularly displaces n9 the opening 67 from the plane of the major portion of the drapery supporting member 61.

The hook element 6t) is formed with a bight section 79, rear leg 71 and elongated shank 72. The hook element may be formed with a crimp '73 such as is illustrated at 31) in FIG. 2 or may be formed as the bight section 59 as is illustrated in FIG. 6. In the drawing, the crimp 73 is intermediate the ends of the bight section 70, similar to the arrangement shown in my copending application Serial No. 788,669. The shank 72 is provided with a series of notches 75 spaced at selected distances apart from the lower end of the shank upwardly. The shank '72 projects through opening 67, with the plane of the hook element on normal to the plane of the arms 63 The book element 6b is rigidly interlocked with the drapery supporting member 61 by the interlocking member 62. This interlocking member 62 is formed of a resilient fiat piece of spring steel formed into the con figuration illustrated. The interlocking member is elon gated in form having a wider lower end as and narrower upper end all. The upper end 31 is formed with a closely fitting hole through which the shank 72 slideably projects. This upper end 81 projects through the loop as and tensions the shank '72 towards the arms 63. An intermediate portion 83 of the member 6?. continuous with the upper end 31 extends downwardly on the forward side of the loop 67 and is arcuately formed at 34 adjacent the lower end 8t). The arcuate portion 554 is formed with an elongated slot extending longitudinally and between substantially the points 35 and 86. The shank 72 projects through this slot. The lower end 3d of the interlocking member 62 is interengaged with the bight section 55. The shank '72 bears against the forward edge of the slot as indicated at 85. Thus the shank '72 is rigidly secured by the interlocking member 62, with the upper end of the interlocking member 62 tensioning the shank in a forward direction against the restraining action of the interengagement of the shank 72 at the pinch 6 5, and the interengagement of the shank 72 with the inner surface of the bight 65. This hook is adjustable by raising and lowering the hook element 659 relative to the supporting member 61. The grooves 75 are interengaged with the hole in the upper end 31 of the member 62.

To adjust the hook, the interlocking member 62 is disengaged at its lower end 8d from the bight 65 by pushing forwardly on the lower end. This frees the shank 72 for vertical movement. The shank is then reengaged by returning the interlocking member to its engaging position.

This particular arrangement lends itself to automatic machines for assembly purposes. In this arrangement the hook may be assembled into a locking engagement by laying the section 83 of the interlocking member 62 on a flat surface with the upper and lower ends 81 and 8h projecting upwardly. The drapery supporting member or is then laid over this interlocking member with the up per end 81 projecting through the loop 68 and the lower end adjacent the bight 65. The shank 72 is then threaded through the opening in the upper end 81, the loop 67 and the slot in the lower end 88. The shank is then pressed towards the fiat surface and the arms 63 causing the lower end 89 of the interlocking member 62 to snap into engagement with the bight are, thereby locking the three elements together.

In FIG. 9 there is shown a further modification of the present invention adapted for use with a pin-on hook. In this arrangement, a crimp 3% is formed in a bight 21 in the same manner as that illustrated in the modifications of FIGS. 1 and 2. In this arrangement the forward leg t corresponding with leg 2% of the modification of FIG. 2, is continuous with the bight section 91 and drapery engaging prong 92, which terminates at its upper end in 6 a piercing point 93. This embodiment may be used in a manner similar to conventional pin on hooks with the added advantage of the crimp arrangement illustrated at 30.
