Application December 9, 1957, Serial; No. 701,605

3 Claims. (Cl. 160-348) This invention relates to a pleat pin used to make french pleats and also to make box pleats for draperies.

It is an object of this invention to provide a pleat pm of inexpensive construction which in use produces an exceptionally beautiful pinched effect to a french pleat.

It is another object to provide a pleat pin having no moving parts.

These and other objects of this invention will become apparent upon reading the following description of the invention taken in connection with the accompanying drawing in which,

Fig. 1 is a perspective view of the six pronged pin,

Fig. 2 is a top view of the pin of Fig. 1,

Fig. 3 is a side view of the pin,

Fig. 4 is a bottom view of the pin,

Fig. 5 is a schematic view showing the manner of consecutively placing the prong elements to form a box pleat into a conventional drapery pleat pin tape sewn to a drape, showing the intertwisting of the two curved front prongs to form a single element inserted in a single tape pocket,

Fig. 6 is a schematic view showing the manner of inserting the pin prongs, with the exception of the two front prongs, into the tape pockets to produce a french pleat and Fig. 7 is a bottom view of a modified pin showing the manner of integrally combining the pin hanger hook with one of the curved front prongs.

Turning to the drawing, the pin of this invention consists of six prongs. The six prongs may be accomplished by means of three substantially U-shaped elements (Figs. 1-4).

The rear U-shaped element 10 is made from rear prongs 11 and 12 and integral bridge portion 13. The middle U-shaped element 14 consists of

prongs

15 and 16 and integral bridge portion 17.

As shown in Figs. 1 and 3, the base of both the

pins

15 and 16 are bent in the same direction to form a sloped portion 18. The bridge portion 17 of element 14 is welded to bridge portion 13 of element 10 in a common horizontal plane.

A front curved substantially U-shaped element 19 is provided with a front prong 20 and a front prong 21. Prong 20 is provided with a rearwardly and outwardly directed top portion 22. Prong 21 is provided with a frontwardly and outwardly directed top portion 23.

The prongs 20 and 21 flare inwardly toward one another so that

top portions

22 and 23 are farthest removed from one another.

The

prongs

20 and 21 diverge from one another upwardly both in a side to side relationship (Fig. 1) and also in front to back relationship (Fig. 3).

As shown in Figs. 1 and 3,

prongs

20 and 21 are each provided with outwardly sloped knee portions 24. The bottoms below the knee portions 24 are turned horizontally inwardly to form horizontal portions 25 located relatively close to one another. Portions 25 of the ele- 2,898,990 Patented Aug. 1 1, 1959 meat 19 are connected to one another by an integral bridge portion 26 (Fig. 4).

A conventional hanger hook 27 is welded to. the bridge portion 26 of element 19 andas shown in Fig. 3 bridge portions 13 and 17 are disposed upon the horizontal por- :tions 25 of element 19.

Turning to Fig. 5, there'is shown a box pleat made by 'use of the pleat pin of Fig. 1. In making this'pleat a conventional pleat pin receiving tape 28 made from two thicknesses of textile sheet material and having a series of consecutive stitched-in spaced-apart prong receiving pockets is sewn by

threads

29 and 30 to the top back of the drape 31.

To prepare the box pleat of Fig. 5, the

front prongs

21 and 20 are interlocked by twisting

portions

23 and 22 into locking relationship to form in effect a single operational prong disposed in a single prong receiving pocket of said tape 28. As shown in Fig. 5 the

prongs

11, 15, 20--21, 16 and 12 are disposed in the consecutive prong receiving pockets of tape 28 and form a beautiful box pleat.

To form a french pleat (Fig. 6), the front prongs 20-21 are not interlocked and they are not disposed in prong receiving pockets of tape 28. As shown in Fig. 6, prongs 11 and 15 are disposed in consecutive prong receiving pockets of tape 28, but front prong 22 is not disposed in a tape pocket but instead is disposed behind the tape 28 intermediate prongs 11 and 15.

Similarly prongs 16 and 12 are placed in consecutive prong receiving pockets of tape 28 in consecutive series relationship after prongs 15 and 11 (Fig. 6) with front prong 23 disposed behind tape 28 and

intermediate prongs

16 and 12.

A modified manner of preparing the pin of this invention is shown in Fig. 7, in this modification the bridge portion of element 19 is eliminated and pin prong 21X is a separate rod welded at its end to bridge portion 13. Also prong 20X is made integral with hook 27X and welded to bridge portion 13 where it crosses said portion 13.

This invention has been shown by means of illustrative examples, but it is not to be limited in its scope to these examples.

Thus only one

front prong

20 or 21 need be provided with a

bent portion

22 or 23 since interlocking of front prong 20 with front prong 21 can be accomplished by a single twisted top portion of but a single front prong.

Preferably the front prongs are provided at their top ends with round knobs to prevent the interlocked front prongs from disengaging.

As shown in Fig. 1, the base 13 of the back element 10 is equal to the base 17 of element 14, but the prongs 11 and 12 are each provided with a flaring section so that the tops of the rear prongs 11 and 12 are farther apart than the distance between the tops of

middle prongs

15 and 16.

I claim:

1. A six prong pleat pin for making selectively box and french pleats in drapery having prong receiving tape sewn thereto comprising a rear U-snaped element having relatively widely flared spaced-apart upright prongs; an intermediate U-shaped element having closely spaced prongs of substantially the same height as said rear element and welded at its base to the base of the rear U- shaped element; a pair of substantially upright front spaced-apart prongs having divergent top portions and of substantially the same height as said intermediate and said rear prongs, welded to said pair of rear and intermediate elements at their base and hook means welded to the base of said rear U-shaped element.
