ABSTRACT OF THE DISCLOSURE A simple and easily used attachment for suspending curtains is described, characterized by having free-running rollers, versatile spring-loaded hook means for attachment to a curtain, a snap-opening cover housing for easy assembly and interchange of parts, and means to hold the sliders in spaced relationship along the track. In one embodiment the curtain slider mounting is adapted to suspend curtains at an angle between tracks at the top and bottom edges of the curtains which are not in the same vertical plane. In another embodiment means are provided to suspend the curtain from the slider in a pleated arrangement from tabs, hooks or button snaps and maintain the pleated arrangement of the curtain at all times. Pleatforming reinforcing means as also disclosed. Other embodiments are disclosed.

7 Claims BACKGROUND OF THE INVENTION Curtain sliders of many configurations are described and used in the art employing various means for attachment of the curtain to the slider, 'various ways of suspending the slider within a track and several forms of springactuated hooks. These devices employ dot-snap fasteners, hooks and slotted members to engage the curtains. In some devices although the hook for attachment to the curtain is spring-loaded, the angle of pull is canted and dependence is had on a button of nylon to engage a slotted track as the slide arrangement. In others, a roller in the form of a ball or double roller which rides in a track such as a split tube is used. Curtains are also hung to travel in a circuitous path. All of these devices are expensive to manufacture, ditficult to assemble and not always practical in use.

The prior art devices are singularly different from the instant device in that the parts of the prior art devices are riveted, the slides are not frictionless and tend to bend and catch, and these devices are not suitable for suspending a curtain at an angle and are not readily convertible so as to be used in this manner. These and other deficiencies in the prior art devices are overcome in accordance with this invention.

SUMMARY OF THE INVENTION This invention concerns a curtain slider having double rollers operating within a cubicle track with a universal housing into which can be assembled a variety of springactuated curtain suspending means and also including a variety of such suspending means. The curtain slider is provided with a snap-on cover on one side of the housing which holds the spring in place, encloses and forms a housing for the spring and provides a guide for the oscillation of the fastening means. A free-moving piston-guide is provided to prevent the suspending means or spring from binding in the housing. The device also includes means for attaching spacing tape, a frictionless guide bushing for the attaching means and sew-on pleat stiffeners for use therewith. A feature of the invention is the adaptability of the device for quick and easy assembly for interchanging parts and for suspending a curtain at an angle before a window or as a partition in a room.

THE PREFERRED EMBODIMENT Referring to the drawings, particularly FIGS. 1, 2, 3 and 12, there is shown a curtain carrier 10 having a housing 12 with side walls 14 and 16, the back wall 18 and the snap-in cover 20. The top wall 22 has the protuberance 24 having the circumferential flange 26 as an integral part thereof. The side walls 14 and 16 carry the axle members 28 upon which the wheels 30 are rotatably mounted. The axles have a radial boss 32 near the end which makes the effective diameter of the axle larger than the bore hole through the respective wheels whereby to retain the wheels on the axles. The housing 12 and its walls and sides with the axles and the protuberance 24 are molded as a single unit and the cover member and wheels are separate units. These parts are preferably molded from nylon or similar plastic having high strength, self-lubrication or anti-frictional properties.

In FIGS. 1 and 2, the carrier 10 is shown in place within the track 40 formed of extruded metal or plastic and provided with the opposing spaced side walls 42 and 44 each having an inwardly depending bottom track or flange 46 and 48 with an upturned inner flange or edges 50 and 52, respectively. The walls 42 and 44 are formed with a top flange or track 54 and 56 also having the inner downwardly depending flanges 58 and 60. U-shaped tracks or box type channels with inwardly turned inner flanges form parallel guides for the wheels 30 and are carried by the integral top wall 62 in spaced relationship by means of the depending flanges 64 and 66. The top wall 62 serves as a means for attaching the track to a structural member or ceiling and floor members where a curtain is to be suspended. The inner surfaces of the 3 flange pairs 46-54 and 48-56 are spaced apart from each other a distance slightly larger than the diameters of the roller wheels 30 and the track is fabricated so that the space 68 is provided to clear the protuberance 24.

Referring to FIGS. 2, 3, 4 and 6, it is seen that the bottom wall 70 of the housing 12 has the Oblong Opening 72 and that the opening 74 in the side 75 has the peripheral recess 76 therearound, extending also into the bottom 70 as indicated at 76. The cover has the flange 78 extending therearound defining a peripheral recessed channel 80 whereby the flange 78 matches with or nests within the recess 76 so that when the cover 20 is fitted against the opening 74, the surface 82 is flush with the side 76.

The cover 20 of the housing 12 has a bottom wall 84 which is flush with the elongated tabs 86 on the inside, but thicker than these tabs on the outside to form the locking seat 88 on the bottom. The back wall 18 of the housing 12 (FIG. 3) has a pair of spaced apertures 90 and 92 therethrough and spaced so as to receive the tip ends of the tabs 86 when the cover is snapped in place. In this position the tabs slide with their bottom surfaces 94 against the inner surfaces 96 (FIG. 4) of the bottom 70. The locking seat 88 is dimensioned so as to slidably fit within the opening 72 but is not as deep as the opening so that once in place the bottom opening is partially closed leaving the space or opening 98 therein.

The drawings illustrate the hook member 100' having the shaft 102 with the nylon washer 104 at the inner end and the spring 106 carried thereon. The end of the shaft 102 is peened at 108 to retain the Washer 104. The washer 104 is relatively thick to act as a guide and move or reciprocate within the housing 12 with the outer periphery engaging the inside flat surfaces of the housing walls. The washer being round does not fit into the corners of the housing. The shank 102 of the hook 100 extends through the opening 98 when the housing is closed (FIG. 8).

In FIG. 3 the cover 20 has been removed and the last flat loop 110 of the spring [106 extends across the opening 72 in the bottom 70* and temporarily retains the assembly with the hook 100 extending out through the bottom opening 72 and the guide washer 104 spaced from the inside of the top wall 22, although the end of the shaft 102 may be against the inside surface. This is the position of these parts as the cover is assembled during which the tabs 86 are forced in the direction of arrow 103 under the bottom loop 110 of the spring 106 guided by the surfaces 96 (FIG. 4) in the sequence shown in FIGS. 6, 7 and 8 to the final position of FIG. 12. In the closed position the wall 88 is flush at the bottom of the bottom wall 70 of the housing 12. The assembly is now unitized, the spring 106 is under slight compression, and, with the rollers suspended in a track, the hook 100' can be used to suspend a curtain 112 as shown in FIGS. 1 and 2 or as in FIG. 14.

A number of different means can be used to detachably aflix a curtain to the roller carrier 10. For instance in FIGS. 1 and 2, the curtain 112 is shown with a tab 114 having the aperture 116 therein to engage the hook 100. The curtain is resiliently mounted from the tab 114 and can be extended or retracted along the track with the rollers 30 traveling freely in the flanges 46, 48. The same type of suspension is used at spaced segments along the curtain and in the preferred embodiment the tracks 40 are attached to the top and bottom of a window opening, as shown in FIG. 14 with the curtain 112 resiliently mounted therebetween at an angle from the vertical from the roller carriers 10. In order to retain some uniformity in pleating arrangement in the curtain, the carriers 10 are oppositely spaced from each other on the curtain between the spaced tracks as illustrated.

Furthermore, the device of this invention can be readily fabricated to include a number of readily interchangeable hooks, i.e., such as the eye member 120 (FIG. 10) shown engaging the hook 122 aflixed to the hem 124 of the curtain 112. Also as shown in FIG. 11 the eye member can 4 carry the snap fastener 126 retained therein and the counterpart of the snap fastener 128 being affixed through the hem 124 of the curtain 112.

It is highly desirable in this art that provision be made to readily adjust the tension on the curtain, provide means to cause the curtain to pleat uniformly and also control the spacings of the points of suspension so that the pleats are retained and the decorative appearance of the curtain is retained in any position, folded or extended. These embodiments are shown in FIGS. 9, 9A, 11A, 12 and 13.

In FIGS. 9 and 9A, there is shown a plastic corner stay member 130 for a pleat having a pair of flat, stiffribbed members 132 and 134 joined at the integral hinge 136. A tab 144 with spaced apertures 146 is an integral part of the stay member, and attached to the hook 100. The hinge 136 can be of thinner material and without ribs. The stay member can also be fabricated without the tab member 144 for use at intermediate pleats between support points along the curtain. The stay 130 is adapted to be sewn upon the inner side of a curtain 112 so that the hinge 136 is at or in line with the fold of a pleat and the members 132 and 134 hold the top edge of each pleat in a planar configuration. The bottom of the curtain can be similarly held in corresponding pleats. The stay member 4130 has the longitudinal reinforcing ribs 138 and a center double rib 140 on each side. The flat areas 142 are thin enough to be sewn through, as at 143, with ordinary needle and thread or machine stitched. The members 132 and 134 are about as long as the pleating desired and a pair of tabs 144 can be the same or different lengths, can be used on each stay member to hold heavy curtains or plastic sheet dividers. Instead of the tab 144, these stay members can have the hooks 122 or the snaps 126-128 molded therein or similarly attached.

An alternative pleat holder is shown in FIG. 11A wherein the snap fastener 128 is molded centrally within the elongated plastic tab 152 which attaches on to the upper or lower edge or hem of the curtain 112. A series of the pleat holders 150 would be used with the snap fastener 126 (FIG. 11) at the top or top and bottom of the curtain in one embodiment. The pleat holders 150 can be stitched, as at 153, to the curtain.

In FIG. '13, there is shown the spacer tape 154 having a series of spaced slots 156 therealong for engagement with the protuberances 24 of the slide carriers 10. The flange 26 is wider than each of the slots 156 so that the protuberance cannot pull out. The slots can be spaced in any desired manner along the tape and are preferably equally spaced from each other to facilitate uniform folding of the curtain. The track 40 is not shown in FIG. 13 but it is apparent that as the carriers 10 are moved apart this spacing is fixed by the tape 154, thus maintaining the pleated configuration of the curtain in unfolded condition. Also, as the curtain is recessed, the tape 154, being flexible, can fold into the space 68 of the track or between the carriers 10. The tape can be fabricated of cloth or plastic as desired.

As seen from this description the invention provides a roller carrier for curtains and the like in combination with a track member which is readily installed, easily used and is adjusted to suspend a curtain at either one or opposite edges and at an oblique angle in the latter instance. Further provision is made for uniform pleating of the curtain and uniform spacing of the curtain in the extended position. The installation shown in FIG. 14 can be assembled with the tracks 40 aligned in an oblique plane if desired. There is sufficient resiliency in the mounting of the rollers and in the guide member 104 to fasten the top and bottom tracks on horizontal floor and ceiling members along lines that are not in the same plane and still retain the oblique relationship of the curtain while also retaining the ease of movement of the curtain. Normally, both tracks would be hidden in recesses or behind decorative cornices or valances as used in modern construction. The curtain 112 can be constructed of any material to form a curtain or wall divider and the assembly can be of any dimensions. The assembly can also be suspended from a non linear track arrangement, that is, the tracks 40 can curve as desired.
