DRAPERY TRAVERSE ROD AND PULLEY HOUSING THEREFOR Filed Sept. 22, 1965 [N VEN TOR. PHILIP l KENNEY ATTORNEYS United States Patent 3,337,903 DRAPERY TRAVERSE ROD AND PULLEY HOUSING THEREFOR Philip L. Kenney, Cheshire, Conn., assignor to The Stanley Works, New Britain, Conn., a corporation of Connecticut Filed Sept. 22, 1965, Ser. No. 489,291 12 Claims. (Cl. 1687.4)

This invention relates to drapery traverse rods, and more particularly concerns the pulley housings located at the ends of such rods.

One of the objects of the present invention is to provide an improved pulley housing for drapery traverse rods comprising low cost sheet metal parts formed to provide superior strength and ease of assembly.

Another object of the present invention is to provide a drapery rod pulley housing arranged to retain the usual drapery glide members on the rod and also to facilitate their removal from the rod when this proves to be necessary.

Other objects will be in part obvious and in part pointed out more in detail hereinafter.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereafter set forth, and the scope of the application of which will be indicated in the appended claims.

In the drawing:

FIG. 1 is a perspective view of a drapery traverse rod embodying the present invention;

FIG. 2 is a cross-sectional view taken along the line 2-2 in FIG. 1;

FIG. 3 is an enlarged cross-sectional view taken along the line 3-3 in FIG. 2;

FIG. 4 is a fragmentary view similar to FIG. 3 but showing the parts as they appear when a drapery glide member is being removed;

FIG. 5 is an enlarged exploded perspective view of the structure shown in FIG. 2; and

FIG. 6 is a fragmentary end view of the drapery traverse rod.

As illustrated in FIG. 1, the drapery traverse rod 19 comprises a pair of telescoping track sections 12, 14 at the ends of which are mounted a pair of substantially identical pulley housings 16, 18. The traverse rod is supported in spaced relation from a window 20 by means of a pair of end mounting brackets 22, 24 which extend into the end portions of the pulley housings 16, 18 respectively in supporting engagement therewith. The end mounting brackets 22, 24 may be secured to the adjacent wall surface surrounding the window frame 20 or to the window frame 20 by suitable fasteners as shown. A pair of drapery carriers 26, 28 and a suitable number of drapery glide members 30 are mounted for sliding movement along the traverse rod 10 and a pull cord 32 is inter-connected with the drapery carriers 26, 28 so as to cause draperies supported in the usual manner on the carriers 26, 28 and the glide members 30 to be opened and closed as desired.

The pulley housing 16 comprises a front wall 34, a top wall 36 and an end wall 38 all integrally formed from a single metal stamping shaped and folded into the configuration best shown in FIGS. 5 and 6. As shown therein, the lower portion 37 of the end wall 38 is formed integrally with the front wall 34 and is bent rearwardly at right angles to the front wall 34 and upper portion 39 of the end wall 38 is formed integrally with top wall 36 and is bent downwardly at right angles to the top wall 36, the two portions being secured together without the use of conventional fasteners by an interlocking tongue arrangement comprising the tongue 40 on the upper portion 39 and the tongue 41 on lower portion 37.

The pulley housing 16 is provided with a channel section 46 which is shaped so as to receive the end of the track section 12 in telescoping relationship with the end of the track abutting a depressed tab 45 formed in the channel section 46, and the resilient detent tongue 47 disposed in the aperture 13 to latch the track section 12 to pulley housing 16.

In order to secure the pulley housing 16 to the end mounting bracket 22, the housing includes a flange 48 extending downwardly from the top wall 36 adjacent the end wall 38 and flange 50 extending upwardly from the lower edge portion of the end wall 38 so as to define a channel in which the free end of the mounting bracket 22 may be secured. For this purpose, a spring arm 52 secured to the top wall 36 and extending downwardly along the end wall 38 so that its lower end portion engages a notch 23 in the lower edge of the mounting bracket 22. As illustrated, the end of arm 52 projects through an aperture 53 in the bottom of the channel formed by the flange 50. This arrangement, together with the engaging surfaces between 40 and 41, reinforce the pulley housing against horizontal loading resulting, for example, from a force exerted on pull cord 32 in manipulating the draperies; it being understood that a forward horizontal force on the bottom of front wall 34 will cause the edges of notch 23 of mounting bracket 22 to engage the arm 52 which will in turn engage the edge of aperture 53 of flange 50 to aid in maintaining the upper and lower portions 39, 37 of wall 38 in interlocked relationship. (See FIG. 6.)

A pair of pulley shafts 54, 56 are rigidly secured to the front wall 34 of the pulley housing 16 and are arranged to provide support for a main pulley 58 and a guide pulley 60. The pulleys 58, 60 are retained within the pulley housing 16 by a cover plate 62 having a pair of apertures 64, 66 through which the end of the pulley shafts 54, 56 extend and a tab 68 positioned in a slot 70 which straddles a dimple 71 on the top wall 36. Preferably the portion of the dimple 71 adjacent the front wall 34 is depressed below the top wall 36 a slightly greater amount than the portion of the dimple 71 on the opposite side of slot 70. The cover plate 62 is secured in place with the edges of the apertures 64, 66 bottomed on shoulders 55, 57 of shafts 54, 56 by a spring clip .72 formed to engage circumferential grooves 73, 75 adjacent the free end portions of the pulley s'hafts 54, 56. In this manner the cover plate 62 functions to retain the pulleys 58, 60 within the pulley housing 16 and also provide support for the free ends of the pulley shafts 54, 56.

Because the traverse rod 10 may be adjusted in length to fit windows of various widths, the number of glide members 30 required to support a particular drapery panel varies in accordance with the width of the panel. Accordingly, it is sometimes desirable to remove one or more of the glide members 30 from the traverse rod 10, and for this purpose the cover plate 62 is formed with an integral flexible glide stop member 74 which extends into close proximity to the end of the track section 12 secured to the pulley housing 16. The glide stop member 74 is formed with an enlarged end portion 76 which normally obstructs the end of the track section 12 and thus prevents the glide members 30 from being shifted out of the track section 12 during use. However, when it is necessary to remove one or more of the glide members 30, the glide stop member 74 may be easily depressed from its normal position shown in FIG. 3 to the position shown in FIG. 4 in which it is deflected sufficiently to permit removal of as many of the glide members 30 as may be desired. In order to prevent the glide stop member 74 from being depressed so far that it might take a permanent set and be incapable of performing its stop function, its root portion 78 is bent sufiiciently away from the plane of the cover plate 62 to shorten the glide stop member so that the enlarged end portion 76 overlies the edge of the cover plate 62 and thus the glide stop member 74 can only be depressed the limited amount illustrated in FIG. 4.

From the foregoing description it will be seen that this invention provides an improved drapery traverse rod pulley housing which is low in cost, and high in strength, and which is easily assembled and disassembled, being formed principally of thin stamped sheet metal parts which may be rapidly assembled to form a structure capable of performing all of its required functions. In addition, there is provided a simple and substantially foolproof arrangement for retaining drapery glide members in place along their track while at the same time permitting such glide members to be easily and quickly removed when desired.

As will be apparent to persons skilled in the art, various modifications and adaptations of the structure above described will become readily apparent without departure from the spirit and scope of the invention, the scope of which is defined in the appended claims.
