DRAPERY GLIDE In (/9)? far o/vvey United States Patent 3,378,879 DRAPERY GLIDE Orville T. Stall, Whittier, Calif. American lieauti Pleat, Inc., 13545 Excelsior Drive, Norwallr, Calif. 90650) Filed May 17, 1966, Ser. No. 550,790 14 Claims. (Cl. 16-814) ABSTRACT OF THE DISCLOSURE A drapery glide adapted to engage with a pair of laterally spaced, parallel rails of a transverse rod and with the upper hem portion of a drapery arranged below the transverse rod including, a unitary block-like body having a substantially rectangular head portion greater in lateral extent than the free gap in the rod established by the rails and having a flat bottom surface to slidably engage the tops of the rails, said head portion being normally arranged with its major longitudinal axis parallel with the rails, a central neck portion depending from the head portion and projecting freely through and between the rails and a lower carrier portion depending from the neck portion and greater in longitudinal and lateral extent than the free gap, a first slot parallel with the longitudinal axis of the structure entering the upper end of the body and terminating adjacent the lower end of the body to divide the upper portion of the body into two laterally spaced, flexible columns whereby the lateral extent of the head portion can be reduced to allow for engagement of the head portion through the free gap by lateral inward flexing of the column towards each other, a second slot on a plane normal to the plane of the first slot entering the lower end of the carrier portion and in which the hem portion of the drapery is arranged, intersecting the first slot and terminating adjacent the upper end of the said carrier portion to divide the lower portion of the carrier portion and define a pair of longitudinally spaced, depending legs to engage the opposite side of the upper hem portion of the drapery, and a unitary wire hanger pivotally carried by the body and having an elongate, longitudinally extending end portion normally arranged in the first slot and engaged on the bottom of the first slot to bridge the second slot and project through the hem portion of the drapery arranged in said second slot.

This invention has to do with a glide and is more particularly concerned with a novel pop-in glide for use in connection with traverse rod drapery installations employing resillient, sinuate pleaters.

In the drapery art, it is common practice to provide an elongate, horizontally disposed traverse rod to support draperies. Traverse rods are simple, elongate, rollformed sheet metal members, C-shaped in cross-section to define a longitudinally extending slot or free gap and defining a pair of straight, flat, longitudinally extending, parallel, laterally spaced rails or rail portions. Such rods are suitably mounted to extend longitudinally above and across a vertical planar area in which it is desired to suspend a drapery. The rods can be arranged with the free gaps disposed laterally or downwardly as circumstances require.

The glide of the present invention is adapted to be related with traverse rods which are arranged with their free gaps disposed downwardly.

The draperies are ordinarily vertical, rectangular fabric panels and are provided with supporting hems along their upper edges to occur adjacent the rod. The upper hems are ordinarily gathered or pleated, or are provided with pleater means.

The upper hem portions of the draperies are secured to the rods by means of a plurality of longitudinally spaced glides, which glides having lower drapery carrier portions; upper head portions which occur within the rods to bridge the free gap and slidably ride on the rails; and neck portions between the carrier and head portions and which project freely through the free gaps of the rods.

With the above general set up, it will be apparent that the drapery panels are suitably supported and are supported in such a manner that they can be shifted laterally, or horizontally, relative to the rods, as circumstances require.

Resilient, sinuate, pleaters established of flat ribbon spring stock engageable in the upper hems of drapery panels are in wide use in the drapery industry. These pleaters are provided with fastener-receiving openings in those portions of the pleaters which extend across or occur on the means longitudinal axis of the pleaters and through which suitable fastening pins, hooks, and the like are engaged to secure the glides to the draperies.

The above-noted drapery construction presents a nurnher of special and unique problems not overcome with standard or conventional hardware and has resulted in the establishment of numerous special and unique glides and means for securing the glides to the drapery and pleater assemblies.

An object of my invention is to provide a novel glide construction for draperies with sinuate spring pleaters having novel drapery and pleater engaging means.

In the drapery art where sinuate spring pleaters are employed, it is or would be desirable and advantageous to initially apply the glides to the drapery and then or subsequently, with the draperies related thereto, engage the glides with their related rods. Unfortunately, the ordinary glides are such that they must be assembled with the rods, by sliding the glides into engagement with the rods at an open end of the rod. Such assembly must ordinarily be performed before the rods are mounted. This requirement prevents or makes impractical. relating the glides to the draperies first and to the rods second.

An object of this invention is to provide a glide of the character referred to which is such that it can be shifted laterally into engagement in and through the free gap of a drapery rod and need not be engaged with the rod from an open or free end thereof; whereby the glides can be advantageously applied to the draperies before being assembled or related to the rods.

The above and other objects and features of my invention will be fully understood from the following detailed description of a typical preferred form and application of my invention, throughout which description reference is made to the accompanying drawings, in which:

FIG. 1 is an isometric view of a portion of a drapery installation employing my new glides;

FIG. 2 is an enlarged side view of my new glides, taken as indicated by line 22 on FIG. 1;

FIG. 3 is an end view taken as indicated by line 3--3 on FIG. 2, with certain parts removed;

FIG. 4 is a top View taken as indicated by line 4-4 on FIG. 3;

FIG. 5 is a view similar to FIG. 3 showing the other end of my glide;

FIG. 6 is a bottom view taken as indicated by line 6--6 on FIG. 5; and

FIG. 7 is a view showing the glide partially engaged with a traverse rod.

The glide construtcion A that I provide is a two-piece assembly involving a body B and a hanger H. The body B is a plastic part established of delron or nylon and is such, that it can be advantageously injection molded. The

hanger H is a metal wire part which is such that it can be easily and conveniently formed by a suitable bending operation and which is such that it can be advantageously related to the body.

The body B of my glide A includes an upper head portion C, a lower drapery carrier portion D and a central or intermediate neck portion E.

The upper head portion C of the body B is a substantially flat, horizontal, rectangular portion having straight, parallel sides 10, rounded ends 11, upwardly disposed top surface 12, and a flat, downwardly disposed bottom or bearing surface 13. The straight, parallel sides and the ends 11 of the head portion C are radiused and/or inclined to extend laterally inwardly and upwardly.

The head portion C is greater in longitudinal and in lateral extent than the free gap G of the traverse rod R with which the glide is to be related and is such that when the glide is engaged with the rod R, the head portion occurs within the rod and the bottom or bearing surface 13 thereof slidably engages the upper or top bearing surfaces of the parallel rail portions R of the rod which portions establish the free gap G.

The lower drapery carrier portion D of the body B of my new glide A is a rectangular block-like portion corresponding in lateral extent with the head portion C, but slightly less in longitudinal extent than the head portion C. The carrier portion D is of substantial vertical extent having a flat, top surface 14 spaced below and opposing the bearing surface 13 of the head portion C and a substantially flat, bottom end 15. The top surface 14 of the carrier portion D is adapted to occur below and to oppose the lower sides of the rail portions R of the traverse rod R and to prevent upward shifting and displacement of the glide A in or relative to the rod.

The carrier portion D is shown as having a flat, vertical ends 16 and vertical sides 17. In practice, to reduce the amount of material to establish the body of my glide and to impart desired resiliency to the body, as will hereinafter be described, the lower portions of the sides 17 of the carrier portion D are relieved as indicated at 17.

The lower portion of the glide body A is bifurcated or slotted as at 18. The slot 18 enters the lower end of the portion D and occurs on a plane extending transverse the longitudinal axis of the glide, that is, from one side to the other side of the glide. The slot 18 serves to define a pair of substantially flat, transversely extending, longitudinally spaced, depending legs at the lower portion of the body and between which the upper hem portion F of a drapery panel I, with a sinuate spring pleater J arranged therein,

can be arranged, as clearly illustrated in FIGS. 1 and 2 r of the drawings.

In the upper portion of the carrier portion D, above the slot 18, I provide a transversely extending bearing opening 21 to receive a portion of the hanger H, as will hereinafter be described.

The slot 18 is of suflicient vertical extent and is of suflicient longitudinal extent to freely accommodate the pleater I with the fabric of the drapery panel I engaged about said pleater.

The neck portion E of the body B is a vertically extending cylindrical portion formed integrally with and extending between the bottom surface 13 of the head portion C and the top surface 14 of the carrier portion D.

The neck portion E is slightly less in diametric extent than the lateral extent of the free gap G of the rod R and is slightly greater in vertical extent than the gauge or thickness of the stock from which the rod G is established- In practice, the neck portion E, depending from the lower bearing surface 13 of the head portion C, extends freely through the free gap G of the rod -R and permits for free rotation of the glide, relative to the rod, on its vertical axis.

In addition to the foregoing, the head portion C, neck portion E and the lower hanger portion H of the glide body B is bifurcated or is provided with a vertical slot 4 30, which slot enters the top end 12 of the body and terminates in the lower portion of the carrier portion D, a short distance above the bottom end 15 of the body.

The slot 30 occurs at right angles to the slot 18 in the carrier portion D and on the normal longitudinal axis of the body. The slot 30 is of substantially vertical extent and intersects the slot 18, as clearly illustrated in the drawings.

The slot 30 in the body B serves to divide the body into what may be termed as longitudinally spaced, vertically, upwardly projecting columns, the lower ends of which are bifurcated by the slot 18 entering the bottom of the lower portion D.

The slot 30 terminates in the lower portion of the carrier portion D at a flat bottom 32. It will be apparent that the bottom 32 is separated into two longitudinally spaced portions by the slot 18 entering the lower end of the body.

The slot 30 is such that it permits for lateral inward flexing and shifting of the columns of the body towards each other. In practice, such flexing and shifting can be such that the lateral extent of the head portion C of the glide body is substantially equal to the lateral extent of the free gap G in the traverse rod, when the columns are flexed laterally inwardly towards each other and so that the upper end of the slot 30 is closed.

With such a relationship, it will be apparent that the head portion of the glide can be engaged through the free gap G of the rod R by simply urging and pushing the head portion, with the plane of the slot 30 extending parallel with the free gap, upwardly through said free gap.

It will be apparent that when the head portion C is arranged adjacent the free gap G in the rod R, with the slot 30 parallel with the free gap and with the upper portions of the upwardly and inwardly inclined sides 10 of the head portion engaging the opposing edges of the rail portions R of the rod R, upon upward urging of the glide relative to the rod R, the inclined sides 10, acting as inclined planes, or cams, flex the columns and the divided sections of the head portion C laterally inwardly towards each other and so that the head portion 10 is reduced sufliciently in lateral extent to pass through the free gap. As soon as the head portion passes through the free gap, the slot 30 opens and the side edge portions of the head portion shift outwardly and so that the bottom surface 13 of the head portion, as noted above, establish sliding bearing engagement on the top surfaces of the rail portions R of the rod.

In practice, the vertical extent of the head portion C can be sufliciently thin so that when the glide is urged upwardly into engagement with a rod R, in the manner set forth above, the side portions of the head portion will or can flex downwardly a limited extent.

By providing for such limited downward flexing of the side portions of the head portion C, the head portion can be made slightly greater in lateral extent than the free gap and the glide, when urged into engagement with the rod, must be snapped or popped into engagement with the rod.

Still further, and in order to provide the head portion C with maximum possible lateral extent and to maintain the slot 30 of minimum lateral extent so as to leave the body with as much stock and strength as is possible, the slot 30 can be made substantially equal in lateral extent with the distance that one side portion of the head portion projects laterally outwardly from the neck portion E.

With such a relationship, when it is desired to engage the glide with a related traverse rod, the glide is arranged below the free gap G in the rod R with the slot 30 thereof parallel with the free gap. The glide is then tipped laterally so that one side edge of the head portion C of the glide projects through the free gap and establishes hooked engagement over its related rail portion R of the rod, as clearly illustrated in FIG. 7 of the drawings. The glide is then manually urged towards said related rail portion of the rod so as to flex the columns of the glide body towards each other and is simultaneously pivoted back towards the other or opposite rail portion of the rod, which pressure and pivoting causes the other side portion of the head portion C to shift upwardly through the free gap and by its related rail portion of the rod.

In this case, as in the previous case, the side edge portions of the head portion C can be slightly over gauged, laterally, so that the last edge portion to be engaged with the rod, when it is urged through the free gap G of the rod, must flex slightly.

In practice, and as illustrated in the drawings, the side walls of the groove 30 can be radiused at their upper e i S, Where they join top 12 of the head portion C, to relieve the body in such a manner that the columns 31 can be flexed a greater distance than would be possible if the sides of the groove were straight and uninterrupted throughout their longitudinal extent. Such radiusing of the sides of the groove 30 and relieving of the construction does not weaken or adversely aifect the structure.

It will be apparent that when my glide is engaged with the traverse rod R, it can be pivoted about its vertical axis and relative to the rod to any desired position without dropping or shifting out of engagement with the rod, and is such that it will and can support considerable weight.

The hanger H that I provide is a simple, unitary bent wire part having an upper U-shaped portion X and a lower hook portion Y. The upper U-shaped portion X has a horizontal primary leg 40 pivotally engaged in the bearing opening 21 in the carrier portion D of the body and bridging the slot 30 therein. A downwardly and laterally projecting base 41 at one end of the primary leg 40 and a laterally inwardly turned, horizontal secondary leg 42, parallel with the primary leg portion 40, projecting laterally inwardly at one end of the body and terminating at the central longitudinal, vertical plane of the body.

The hook portion Y of the hanger H is a longitudinally extending portion and includes a substantially straight downwardly and laterally inwardly projecting primaly arm portion 43 extending from the inner end of the leg 42 of the laterally extending U-shaped portion of the hanger which arm portion 43 projects laterally inwardly and downwardly through the slot 30 in the body and terminates within the slot 18 in the body, below the bottom 32 of the slot 30. The hook portion Y further includes a second-ary arm portion 44 extending or continuing from the lower inner end of the arm portion 43 and projecting laterally outwardly and upwardly from within the slot 18 and into the slot 30. The outer free end of the arm portion 44 is sharpened as at 45 to facilitate the hook portion piercing the fabric of a drapery.

It will be apparent that the lower portion of the slot 30 is divided longitudinally into two end portions by the slot 18 entering the lower end of the body and the primary arm portion 43 of the hanger H extends through one lower end portion of the slot 39 and that the secondary arm portion of the hanger H projects into the other lower end portion of the slot 30.

The lower inner end portions of the primary and secondary arm portions 4-3 and 44 of the hook portion Y of the hanger H bear against and are supported by the corners established by the walls of the slot 18 and the adjacent portions of the bottom 32 of the slot 30.

With the above relationship of parts, it will be apparent that the central upwardly opening bend d6 of the hook portion Y of the hanger H, established by the primary and secondary arm portions 43 and t4 normally occurs within the slot 18 and below the bottom 32 of the slot 30. Accordingly, in order to shift the hook portion Y, about the axis of the upper primary leg 41] of the upper portion X, and to shift the secondary arm 44 of the hook portion Y out of engagement in the spot 1-8, the hanger H must be sprung slightly so as to cause the central upwardly opening bend 46 to ride upwardly and over the ad jacent portion of the bottom 32 of the slot 30.

With the above relationship of parts it will be apparent that the hanger H is, in effect, spring loaded and is yieldingly maintained in its normal position, as illustrated in full lines throughout the drawings, and is such that it can be snapped out of said normal position to an open position, such as is illustrated in phantom lines in FIG. 2 of the drawings.

In operation or practice and when it is desired to connect the glide with the drapery I and pleater J, the hanger is shifted to its open position. The glide is then shifted into engagement with the assembled drapery and pleater so that the hem F and pleater J are arranged within the slot 18 and so that a pin receiving opening 50- in the pleater occurs adjacent the bottom 32 of the slot 30. When the glide is thus arranged with the drapery and pleater assembly, the hanger is pivoted so that the secondary arm portion 44 of the hook portion Y swings laterally inwardly, piercing the fabric and projecting through the opening 50 in the pleater. When the hanger is thus shifted and returned to its normal position, it will be apparent that the drapery and pleater assembly is positively hooked by the hanger and is supported against vertical displacement from within the groove 18 thereby.

It will be further apparent that the weight of the drapery and pleater assembly carried 'by the hook portion Y of the hanger is not transmitted to and through the upper portion of the hanger, but rather, is transmitted directly onto the longitudinally spaced columns at the bottoms 32 of the slot 30.

In practice, when it is desired to shift the hanger from its normal to its actuated position, the operator of the construction can so shift the hanger by engaging the base portion 41 and/or the secondary leg portion 42 of the upper portion X of the hanger with his fingers.

It is to be noted that the hanger H can be easily and conveniently assembled by arranging the upper leg portion 40 in axial alignment with the bearing opening 21, at one side of the body, turn the hanger to an extreme open position and then shifting the leg portion 40 axially into engagement in said bearing opening and to a position when the plane of the hook portion Y occurs in the plane of the slot 30; whereupon the hanger can be rotated to its normal position.

It will be apparent that the hanger, being yieldingly engaged in or with the body, is not subject to being accidentally disengaged therefrom and lost. Accordingly, my new construction is such that it can be advantageously assembled and subsequently stored, shipped, handled and otherwise manipulated without the possibility of the body and hanger becoming disassembled.

Having described only a typical preferred form and application of my invention, I do not wish to be limited or restricted to the specific details herein set forth, but wish to reserve to myself any modifications or variations that may appear to those skilled in the art and which fall within the scope of the following claims.
