This invention relates generally to window shades and embrace particularly a simple arrangement for securing; the upper edge; of the. shade-to the shade roller by the use of pressureresponsive adhesives,
The adhesive bonding structure is intended for replacement shades which aresold without rollers,- that the: purchaser can attach them. quicklyv and conveniently to the existing rollers athome... mode of attachmentv is: especially useful mounting shades. formed of synthetic plastic sheets. such as. vinylplastic and similar, materials. whichare. quite popular for window shade use.- However such materials. are: soft. inv texture and cannot,- be satisfactorily attached to the rollers. by tacks or staples as is customary with cloth paper, or; fibre shades. Theplastic isquite tough, but. ithas a tendency? whenv rolled tightly upon the; roller, to be indented or impressed permaenently with,v the protruding heads of the tacks, or staples. These. are visible irrr-ows across. the: shade whenitis lowered and. spoil. its-appearance.
Bonding the shade, to the roller by mean of a. continuous adhesive. strip. eliminates this. damage and, also, makes. the. job. considerably easier for the; housewife who. has difllculty in tacking the; edge- 0f: the shade. straight. and. smoothly to.- the ro1l'er., Also the; plastic, sheet. does. not possess, agree-t. deal. of resistancetc, tearing. when pierced; by.- tacks or staples, whereas, the adhesive strip. provides; a: continuous, strong. bond. between. the. shade. and; roller.
"One of the primary objects or the. invention has been to provide a, shade havingv a pressureresponsive adhesive strip mounted upon its, up? peig, edge andgpresenting a permanently tacky surfaceyior attaching. the shade. to, its roller. This allows theshade to be stretched and aligned with, the; roller; then bonded by. pressing. it in place in, straight smooth condition;
Another object has, been to provideapressureresponsive adhesive mounting, strip having sufficient, adhesivenessj to bondthe shade securely to the; r. .1l t;.. but which allows the. shade: to; be, str pped cleanly. fromgthe, roller, for replacement". with alIlQWfsh'adb when necessary.
A; further," object has been. to providev in. cone nection; with apres'sure-responsivestrip a facing, strip which. overlies the tacky surfaceof the adhesive, to preventv air-drying, the facing strip being adapted to; begpeeledlfromthe adhesive, strip mics tomounting the. shadein order to-provide a.c ,an= and freshadhesive surface which will bacdrcflilv; to. he s riaceor the; roll r-z The i=1at.tenable.-v nature of; the; exposed; adhesive; coat.-

FOr the same? reason, the" facing strip-can; be peeled easily from: the: adhesive strip, leaving all of the adhesive coating upon" theshade and exposing itin fresh tacky-condition.
Although the structure is intended particularly for plastic shades, itis" also contemplated to an plythe pressure-responsive stripitolshadsfbrmedl of cloth, paper and fibrous material's andtherepv; to facilitate the mounting and. dismounting; off themjin the same manner. Other features and advantages of the invention will be, more fully described inv the following specification; taken in: conjunction-with the drawings.
In the drawings: 4 V Figure 1. is; a generalview of: ashadd and rcllen combination. withthe. shadez-secureda to,- tharhllen 3 by means of the pressure sensitive strip of this invention.
Figure 2 is an enlarged fragmentary view simiar to Figure l, but showing a portion of the adhesively bonded end of the shade pulled away from the roller to illustrate the strip arrangement.
Figure 3 is asectional view taken on line 3-3, Figure 2, further detailing the adhesive bond between the edge of the shade and roller.
Figure 4 is a fragmentary view of the shade before attachment to the roller with a portion .of the facing strip peeled back from the adhesive strip preparatory to mounting it upon a roller. The adhesive strip is permanently bonded to the surface of the shade but in this view is shown peeled back to expose the adhesive coating which bonds it to the shade.
Figure is an enlarged exploded View taken on line 55, Figure 4, more clearly illustrating the relationship of the adhesive coatings of the adhesive strip illustrated in Figure 4.
Referring particularly to Figure 1 of the drawings, the shade is indicated generally at H) and its roller at H. The roller is conventional, being formed preferably of wood and having the usual spring winding mechanism and including end caps I2-l 2 and pins l3l 3 for mounting the roller in the shade brackets. The upper edge of the shade is secured to the roller by means of the pressure sensitive adhesive strip indicated generally at M, which is provided with a coating of pressure-responsive adhesive material on both sides. This strip is interposed between the edge of the shade and the roller, one adhesive coating securing the strip to the shade and the other securing the strip and shade to the roller.
adhesive is of the type which unites securely to the surface against which it is pressed. It is permanently tacky and permits removal of the shade when it becomes worn by grasping an edge and peeling it from the roller.
The, adhesive mounting strip is of particular advantage'in connection with the shades formed of plastic sheet material because such material has a tendency to split or tear if it is tacked to ig the shade in the usual manner of cloth shades. The soft pliable nature of sheet plastic allows the outline of the tacks or staples to be impressed into the convolutions of the shade when it is rolled up. Thus, the entire shade will have impartedto its surface at spaced intervals the impression of the tacks or staples and these markings naturally detract from the otherwise smooth and attractive appearance of the shade when it is pulled down.
In its preferred form, the replacement shade is supplied to the user with the double-sized adhesively coated strip mounted permanently upon the 'upper edge of the shade. In order to preserve the tackiness of the exposed adhesive surface IS, a facing strip it (Figure 4) is applied over the exposed coating. This facing strip may be formed of strong paper, Cellophane, or similar material and is slightly wider than the adhesive strip M to provide an overhanging loose edge as indicated at I! (Figure 5). This edge may be grasped by the user to strip the facing from the adhesive strip as indicated. The facing strip not only prevents air-drying of the otherwise exposed surface, but also prevents dust and dirt from becoming deposited upon it and thus keeps the coating in fresh tacky condition.
The adhesive strip I4 consists of a base strip is formed of paper or a plastic material such as Cellophane and has on both sides, a deposit or coating of the pressure-responsive adhesive material. The coating I9, which bonds the strip permanently to the shade, is adhesively stronger than the coating [5 which bonds the shade to the roller. The strip is applied to the edge of the shade by the manufacturer with the facing strip applied over it ready for use. It will be apparent therefore, that both adhesive coatings are protected from air-drying since one coating is permanently sealed between the shade and the adhesive strip while the second coating is temporarily sealed between the adhesive strip and the removable facing strip.
Although the structure is disclosed in connection with a plastic shade, it can be applied to cloth and paper shades with equal facility. In like manner it is not restricted to mounting shades on Wooden rollers, but is equall effective in applying shades to rollers formed of fibre and other materials. The pressure-responsive adhesive coatings are of a well known commercial grade which provide a high degree of tenacity once applied to a bonding surface but which, as noted above, are disparate in adhesiveness such that the facing strip can be peeled cleanly, and
likewise allowing the shade to be peeled from the roller Without the adherence of adhesive patches to the roller.
Having described my invention, I claim:
1. A replaceable window shade unit adapted coating deposited on both sides thereof, the said coatings being of disparate adhesiveness on opposite sides of the said strip, the strip being bonded permanently to the surface of the shade' along the upper edge thereof by the coating hav ing the greater adhesiveness, the upper edge of the adhesive strip being flush with the upper edge of the shade adapting the edge to be aligned with the axis of a shade roller for mounting the shade thereon, the other of said coatings being.
adhesively bendable to the roller upon pressing the upper edge of the shade against the roller. .2. A replaceable window shade unit adapted to be mounted adhesively upon a shade roller'f comprising, a shade formed of synthetic plastic material, a thin flexible paper strip having a tacky, pressure-responsive adhesive coating deposited on both sides thereof, the saidfcoatings being of disparate adhesiveness on opposite sides of the paper strip, the paper strip being bonded permanently upon the surface of the window shade along the upper edgethereof by the coating having the greater adhesiveness, the upper edge of the paper strip being flush with the upper edge of the shade adapting the edge to be aligned with the axis of a shade roller for mounting the shade thereon, the second of.
said coatings'being adapted to bond the upper edge of the shade to the shade roller upon pressing the same against the surface of the roller;
the said coating providing a detachable adhesive bond between the shade and roller which 131 0-9- '5 vides suflicient strength for normal usage, but which allows the shade to be stripped forcibly from the roller by peeling the same progressively across the roller.
3. A replaceable window shade unit adapted to be mounted adhesively upon the periphery of a shade roller comprising a shade formed of thin readily deformable plastic sheet material, an adhesive strip formed of thin pliable sheet material having a substantial width, the strip having a tacky pressure-responsive adhesive coating deposited upon both side thereof, the said coatings being of disparate adhesiveness on opposite side of the said strip, the upper edge of the adhesive strip being flush with the upper edge of the shade with the strip bonded to the upper margin of the shade by the coating having the greater adhesiveness, the coating of lesser adhesiveness thereby providing an ad- REFERENCES CITED The following references are of record in the file of this patent:
