This invention relates to replacement window shade structures and the like.
An object of the invention is to provide for a high degree of facility in attaching window shades to shade rollers of the spring wound type, either in the replacement or the initial application of the shade web to a roller.
Another object of the invention is to provide means for proper and accurate application of a shade web to a roller, Without the need for complicated and expensive factory operations, and with a substantial saving of time, expense, and skilled labor costs; the same means being of advantage in the replacement of window shade webs to existing rollers in the home.
Other objects of the invention are: to provide for reversal of a shade web upon a roller, to conceal soiled portions thereof; to provide a novel and useful replacement shade package wherein the shade is protected against injury during handling and shipment; to provide means whereby a replacement shade may be applied to any proper available roller without having to unroll the shade prior to hanging thereof; and to bviate all possibility of an unsatisfactory home application of replacement shades to used rollers.
These and other objects are attained by the means described herein and disclosed in the accompanying drawing, in which:

The history of the art to which this invention relates indicates that some satisfactory method of rendering window shades replaceable upon shade rollers, has long been sought. It has been proposed, for example, to apply tubes or cylinders of cardboard, metal and the like, to the upper end of a replacement shade for fa- LLI cilitating application thereof to existing rollers. There has been no evidence, however, of any noticeable commercial success in connection with those proposals, the failure of which is believed to be attributable to excessive costs and to the difficulty of maintaining a fixed relationship of the shade web to the roller. Some of the prior methods also failed due to the fact that the practice thereof required a degree of skill not ordinarily possessed by the purchasing public, in the matter of applying the replacement shade. One of the primary objects of the present invention is to avoid all necessity for extraordinary skill or care in the application of replacement shades to existing rollers, and to so simplify the structure that the cost thereof will be within reach of the public generally,
With reference to the accompanying drawing, and especially to Fig, 2, the replacement shade of the invention is seen to comprise a single thickness of shade material I2, which may be of paper, fabric, or other suitable material properly coated or otherwise treated to impart thereto the necessary characteristics expected in a window shade or the like. At its upper end, the web I 2 is turned upon itself to form a hem or cylindrical loop l3 of the proper size for reception of standard shade rollers. Since standard shade rollers vary to some extent in diameter, the hem or loop is made sufliciently large to accommodate the largest of the ordinary size of standard rollers. Where the free upper edge M of the web is fastened upon itself, resort may be had to stitching I5 or any other acceptable means of fastening, such as an adhesive or clips or clamps of one kind or another.
In the embodiment illustrated by Fig. 2, a portion of the inner face I5 of the hem may carry a narrow longitudinal adhesive coating or strip H, which by preference extends from one side edge of the shade web to the other. The adhesive coating preferably is one which is soluble in water or other liquid. To insert a roller into the hem or tubular portion l3, and to produce the necessary connection or fastening of the web to the roller, it is necessary only to moisten the roller prior to inserting it into the hem, thereby rendering the adhesive tacky and causing a bond with the surface of the roller. As will be understood, the setting of the adhesive will result in a substantial fixation of the roller within the hem or tubular portion l3 of the replacement shade.
At the lower end of web l2, the free edge I8 is turned upwardly and fastened by means of a line of stitching H! or its equivalent, to furnish a second loop or hem 23 adapted for reception of the customary reinforcing bar 2|. The hem or loop 20 may be dimensioned to snugly receive the reinforcing bar, if desired, but in the form of the invention disclosed said hem is made sufficiently large to accommodate a standard shade roller in a manner similar to the hem or loop l3 at the upper end of the shade. The purpose of this is to enable the user to reverse the shade, that is, to suspend it from either one of its ends, so as to conceal as much as possible any soiled areas of the shade material.
The illustration of Fig. 1 shows how the replacement shade of Fig. 2 may be spirally rolled into package formation for protecting the shade during handling and shipment, at little expense and with the advantage of great convenience. It will be noted that in the package form, the shade is Wound with the hem or loop l3 disposed exteriorly, and with the reinforcing bar 2| transferred to the web or loop that would customarily receive the roller. Thus, the hem or loop 20 is disposed interiorly of the package, and does not, in the package formation of the shade, support the reinforcing bar. Accordingly, the application of the Fig. l shade to a roller requires merely the shifting of the reinforcing bar 2| to the interior hem or loop 20, and the insertion of a moistened shade roller into the exterior hem or 100p IS without unwinding the package prior to suspending the ends of the shade roller from the window brackets. The package of Fig. 1 may easily be wrapped with paper to protect the shade from soil, while the exteriorly disposed reinforcing bar effectively prevents injurious bending or cracking of the shade material during handling and shipment. It is of great advantage to be able to apply the shade to a roller Without having to unroll the shade before suspending it from the window brackets.
In the modification of Fig. 3, the shade web I 2 has its upper looped end 22 furnished with an adhesive coating 23 extending from the free edge 24 of the web to a location 25 at one side of the hem, so that the adhesive coating may serve initially as a means of maintaining the loop formation, while at the same time functioning in the manner of the coating ll of Fig. 2. In this case, the stitching may be dispensed with, if desired.
In the modification, Fig. 4, the line of stitching 26 maintains the loop formation; one or more tacks or other fasteners 21 are driven into the roller 28 for fixing the loop or hem to the roller, thereby dispensing with the use of an adhesive entirely. In this view, the character 25 indicates a pintle on one end of the shade roller, reinforced by an end flange 36), in accordance with customary practice. The pintle end flange are shown also on Figs. 5, 6, and '7.
In a shade structure such as illustrated by Fig. 4, wherein the web carries no adhesive coating, it may be desirable to employ a shade roller such as is disclosed in Fig. '7, wherein a narrow longitudinal strip 3! of adhesive is furnished upon the roller itself. As will readily be evident, the roller of Fig. 7 may be inserted into a shade hem or loop of the Fig. 4 type, after first moistening the soluble adhesive area 31 of the roller, thereby rendering it unnecessary to use tacks or other fasteners 2'! for establishing a fixed relationship of the roller to the shade hem or loop.
With reference now to Fig. 5, the web l2 has its upper end turned upon itself, and secured by means of a line of stitching or the like 32 to provide a hem or loop 33, in substantially the same manner as heretofore explained. Along the length of the hem or loop, a series of perforations 34 are formed, so that a portion of the roller will be exposed after the roller has been inserted into the hem or loop. After insertion of the roller, an adhesive patch 35 is applied to the web. over and about each of the apertures 3 1, so that the patch will stick to the surface of the roller Where it is exposed, while at the same time fastening itself to the shade material along the margins of each aperture. Application of the patch as explained, will effectively anchor the shade material to the roller, so that relative movement between the roller and the hem will not occur. In the preferred form of this modification, the apertures 34 will be formed in the hem with the major axes thereof disposed circumferentially about the roller, thereby to furnish the greatest possible anchorage for the roller. At the extreme right of Fig. 5, the aperture is disposed with its major axis extended lengthwise of the roller, so that this arrangement is possible also. When the shade of Fig. 5 is constructed of strong sheet material, the adhesive patch may be of the kind wherein the adhesive element thereof is non-drying, and in that case it will be possible to repeatedly apply and remove the adhesive patches whenever it becomes necessary to launder the shade material. However, when the shade material is of inexpensive paper, it may be preferable to apply less expensive adhesive patches formed from gummed paper or the like. In either event, the structure shown in Fig. 5 furnishes an ac curate, convenient and inexpensive way of applying replacement shades to existing rollers.
The structure of Fig. 6 is a variation of that disclosed in Fig. 5, but it includes the punching of apertures 36 in the material forming the hem, although in this variation a flap 31 is permitted to remain along one longitudinal edge 38 of the aperture. The flap, after insertion of the roller into the hem, may be adhesively fixed to the area 39 of the roller where exposed through the hem aperture. The drawing figure indicates at 60 a suitable adhesive on the flap, to be pressed against the roller area 39 subsequently to positioning the roller within the web. The adhesive coating may be applied to the web by the purchaser, or it may be applied at the shade factory in the form of a soluble gum or the like, to be moistened by the purchaser at the time of placing the shade upon the roller.
In each of Figs. 5 and 6, the various apertures may be formed of any desired contour, including circular and ovate shapes as well as angular shapes of various designs. In Fig. 6, as well as in Fig. 5, the adhesive flap may be repeatedly applied to or removed from the roller provided that the shade material is of such qua].- ity and character as to withstand the repeated manipulations. As in all other forms of the invention, the rows of stitching indicated at 32 in Figs. 5 and 6 may be replaced by suitable clips or clamps, or an adhesive connection.
It is important to note that the shade structures of Figs. 2, 3, and 6 may be constructed of a material which is water pervious, especially at the hem or loop, so that fixation of the shade to a roller may be achieved by first inserting the roller into the hem or loop, and thereafter applying Water or other solvent to the outer surface of the hem or loop material, the water or solvent thereby acting to penetrate the shade material for rendering the interiorly disposed adhesive sufliciently tacky to effect a bond with the roller. This is an improvement which greatly facilitates and simplifies the application of a replacement shade to a shade roller.
In Fig. 7, the strip of adhesive indicated at 3| may be a paper ribbon initially carrying adhesive on both of its faces, and applied to the roll so as to expose one of the adhesive faces to the inside of the hem or loop portion of a shade.
What is claimed is:
1. A window shade structure comprising a shade roller, a single thickness web of shade material having a pre-hemmed end in which the roller is inserted by moving it longitudinally through the hem, and fastening means cooperating with the roller and the hem portion of the shade for precluding rotation of the roller therein, said fastening means comprising an adhesive rendered effective for so precluding rotation, only after insertion of the roller into the hem.
2. A replacement window shade, comprising a single thickness web of shade material having an end for association with a shade roller, said end being hemmed initially and dimensioned to receive a shade roller therein, and a normally dry adhesive means associated with the hem permitting free insertion of the roller therein, said adhesive being rendered tacky by moistening through the web subsequently to insertion of the roller into the hem.
3. A replacement window shade, comprising a single thickness web of shade material having opposite ends each turned upon the body of the web to provide opposed hems each dimensioned to receive alternatively a shade roller therein, whereby the shade may be hung from either end depending upon a soiled condition of portions of the shade, and a soluble adhesive within the confines of at least one of the hems, to be rendered tacky by exterior application of a solvent through the material of the web subsequently to insertion of a roller therein.
4. In a device of the class described, the combination of a window shade roller, a shade web having a perforated end turned upon itself and fastened to provide a hem in which the roller is disposed, and an adhesive patch applied exteriorly upon the hem and over the aperture thereof to contact and fix the roller relative to the hem and the patch.
