[451' July 22, 1975 [57] ABSTRACT A master slide for supporting drapery on a slotted rod which includes an upright slide body having a depending skirt. A bracket having a base portion and supporting arm is seated on the front of the skirt. The mounting surface on the bracket and the face of the depending skirt are formed in a series of mating scallops permitting register of the bracket in a selected one of a plurality of horizontal positions and with the bracket pointing either to right or left. The mounting surface of the bracket is rockered" in a horizontal plane with respect to the face of the skirt so as to permit the arm on the bracket to be adjusted in angle inwardly and outwardly with respect to the slide body to change the degree of overlap clearance between adjacent leading edges of the drapery, and with a screw clamping the parts in their adjusted relation. The arm is channeled out symmetrically on both sides so that it is of H cross section having spaced parallel uprights which support between them a horizontal web having holes therein for supporting the rear leg of a drapery hook in both directions of extension of the arm.

8 Claims, 9 Drawing Figures It is an object of the present invention to provide a master slide for supporting the leading edge of a section of drapery in which the drapery-supporting arm thereon may be secured to the slide body in a selected one of a plurality of horizontal positions and with the arm bearing a selected angle with respect to the slide body thereby to adjust the degree of horizontal extension of the bracket, and the drapery which is supported thereon, as well as to vary the overlap clearance between adjacent leading edges of the drapery.

It is another object of the present invention to provide a master slide having a slide body and a bracket in which the bracket, in addition to adjustment of register and angling, may be reversed end for end with respect to the slide body. This permits the master slide to be used in the conventional way as a right-hand slide cooperating with a left-hand slide or to be used as a lefthand slide for abutting relation with a right-hand wall.

It is a general object of the present invention to provide a master slide for supporting drapery which is formed of two pieces molded in plastic and secured together by a single clamping screw to provide a highly versatile assembly enabling horizontal adjustment of the leading edge of the drapery to control amount of overlap, enabling adjustment of overlap clearance, and permitting both right-hand and left-hand modes of use, all in a structure which can be economically manufactured and easily and permanently adjusted by the drapery installer for carefree operation over long periods of time.

Other objects and advantages of the invention will become apparent upon reading the attached detailed description and upon reference to the drawings in which:

FIG. 1 is a plan view of a master slide construction in accordance with the present invention.

FIG. 2 is a front view of the master slide of FIG. 1 but with the slides separated from one another.

FIG. 3 is a left-hand end view of FIG. 2.

FIG. 4 is a right-hand end view of FIG. 2 with the rod shown in cross section.

FIG. 5 is a back view looking along line 5-5 in FIG. 1.

FIG. 6 is a plan view in partial section looking along the line 6-6 in FIG. 4 but with the parts separated from one another.

FIG. 7 is a view similar to FIG. 6 but showing the parts assembled and the range of horizontal and angular adjustment permitted by the present invention.

FIG. 8 is another view similar to FIG. 6 but showing the arm of the bracket in its reversed position.

FIG. 9 is a fragmentary cross section looking along the line 99 in FIG. 6.

Turning now to the drawings there is shown, in FIGS. 1 and 2, a master slide assembly including a right-hand master slide 11 and a left-hand master slide 12. It will be understood that the master slides are intended to cooperate with one another carrying, cantilever fashion, the leading edges of a set of draperies with the leading edges being closable in overlapping condition. The right and left-hand slides are supported upon a slotted rod 13 which is shown in cross section in FIG. 4, with the horizontal slot at the rear of the rod being indicated at 14. i

Turning attention to the right-hand master slide 11, it includes a slide body having runners 15,15a along its upper edge which cooperate with lands on each side of the slot 14 so as to support the body in upright position. Along the lower edge of the slide body is a depending, horizontally extending skirt 16 which hangs below rod level and which has a face 17.

Mounted upon the skirt l6 and extending forwardly below rod level is a bracket 20 having a base portion 21 and a horizontally extending arm 22 which supports the right-hand leading edge of the drapery cantilever fashion. The base portion of the bracket has a mounting surface 23, as in FIG. 6. In accordance with the present invention the mounting surface on the bracket and the face of the depending skirt are formed as a series of mating scallops dimensioned to permit register of the bracket in a selected one ofa plurality of horizontal positions thereby to control the degree of horizontal extension of the bracket, and drapery thereon, with respect to the slide body which, in turn, controls the degree of overlap at the leading edges of the drapery. Specifically, the face 17 of the slide body isformed with concave scallops 31, 32, 33. The bracket has registering

convex scallops

34, 35, the scallop 34 being conveniently referred to as the main scallop on the bracket.

To provide additional support and alinement between the slide body and the bracket, with the bracket facing either to the left or to the right, the skirt on the slide body has a horizontal groove 40 therein (FIG. 4) defined by an upper wall 41 and a lower wall 42. The groove 40 is of constant width. and the thickness dimension of the bracket is such as to snugly fit into the groove to resist the twisting force upon the bracket resulting from the cantilevered support of the drapery.

For the purpose of clamping the parts together regardless of the direction of the bracket and in any selected horizontal position, a clamping screw 45 is provided which engages a tapped hole 46 formed in the main scallop 34 of the bracket, the screw having a set of clearance openings in the form of

horizontal slots

47, 48, 49 formed in the concave scallops 31, 32, 33, respectively.

It will be apparent, then, that the bracket has three positions of horizontal adjustment upon the slide body, that is, the scallop 34 can be selectively mated with the scallops 31, 32 or 33 on the body.

In accordance with one of the features of the present invention the concave and convex scallops are relatively rockered with respect to one another so that, in addition to the horizontal positioning, the bracket may be rocked angularly for inward and outward swing of the arm 22 thereby to adjust the degree of overlap clearance of the right-hand edge of the drapery with respect to the left-hand edge. In the present construction the concave scallops are located along a straight locus 51 shown in FIG. 6 while the locus of the scallops on the bracket is curved or rockered as indicated at 52. Thus regardless of the registered position of the bracket upon the slide body, the bracket may nevertheless be rocked through a limited angle inwardly and outwardly as indicated by the various dot-dash positions shown in FIG. 7. It will be understood that while it is convenient to make the bracket the rockered element, the relationship could be reversed, that is, the locus of the scallops on the bracket could be straight while the locus of the scallops on the slide body could be convexly curved. In either event, the curvature (for example of the locus 52) is quite limited so as to intentionally limit the degree of rocking movement so that in all of the angular positions of the bracket the bracket is still fully registered with the slot 40 which receives it and thus fully supported horizontally, from end to the other, to resist the vertical twisting force imposed by the weight of the drapery.

While, in the present construction, the slide body and base portion of the bracket both are provided with plural scallops, it will be understood that it is not necessary to haveplural scallops on both of these elements and that selective positioning can be achieved by, say, providing a series of concave scallops on theslide body and only a single convex scallop, for example that indicated at 34, on the bracket.

in accordance with one of the aspects of the invention the bracket is channeled out symmetrically on both sides so that it is of H cross section having spaced paralleluprights which support between them a horizontal web having holes spaced therealong for supporting the rear leg of a drapery hook in upright position in both directions of extension of the arm. Thus referring to FIG. 9, the arm 22 has a channel 61 on the top and a symmetrically formed channel 62 on the bottom defined by uprights 63, 64. The uprights support a central web 65 having a series of holes 66. The holes serve to receive the rear leg 71 of a drapery hook 70. With the arm on the bracket oriented to the left as shown in FIG. 6the H-shaped cross section will be seen to apply to the I hook a force couple consisting of an upper horizontal force F1 and a lower horizontal force F2 exerted by the I the upper edge of the upright member 63 and the lower edge of the upright member 64. This insures that the hook 70 is supported in the upright position shown regardless of the amount of weight exerted by the drapery. When the bracket is switched around to face in the opposite direction illustrated in FIG. 8, the same support in upright position is assured but the functions of the uprights 63, 64 in the arm cross section are reversed. ln addition to holding the hook 70 upright in both the right and left-hand modes, the H cross section has the further advantage of high inherent strength because of its l beam" construction.

It is preferred to mold the two parts of the master slide of plastic, with the runners and depending skirt of the slide body being molded integrally and with the base portion and arm of the bracket also being integral with one another. The type of plastic is, of course, a matter of designers choice depending upon the anticipated weight of the drapery and the type of service for which the master slide is intended. It will be apparent to one skilled in the art, however, that even with the master slide formed of-an inexpensive type of plastic and in relatively light section the tongue and groove connection between the two pieces and the channeled cross section forms a structure which is inherently strong. The clamping screw 45 is stressed primarily by the clamping forces and holds the parts intimately together without, however, having to bear the full weight of the drapery which is, instead, primarily borne by th interfitting surfaces of body and bracket.

While the above discussion has been primarily concentrated upon the right-hand master slide 11, the lefthand master slide 12 with which it cooperates is of relatively simple construction, and corresponding parts have been indicated, where applicable, with corre- -22a of the bracket is of the same inherently strong H cross section and that similar means are provided for maintaining the, left-hand slide in its upright position with respect to the supporting rod.

While the invention has been shown and described in connection with rocking action between a pair of members having smoothly continuous convex and concave mated surfaces, and while this constitutes the preferred embodiment, it will be understood that both surfaces need not be smoothly continuous. It will be apparent to one skilled in the art that one of such surfaces may be discontinuous as long as the desired rocking action is achieved and that the term mating scallops includes this possibility. Moreover, at least one of the mating surfaces, instead of being perfectly smooth, may be formed with shallow teeth to provide small steps of angular adjustment without departing from the present invention.
