Description

  The present invention relates to a pull-up type curtain that is used to form a pull-up type curtain that can be pulled up in a state where fold-like folded portions are stacked, and a pull-up type that is configured by using the pull-up type curtain. More particularly, the present invention relates to a pull-up curtain device configured using the pull-up curtain.

  In recent years, a pull-up curtain device that can be pulled up in a state where fold-like folded portions are stacked has gained popularity. As a general one of this kind of curtain device, for example, as shown in FIGS. 46 to 47, a sheet-like fastener b is formed on the indoor side surface portion of the support bar a provided along the upper edge of the window opening. The upper edge portion e of the curtain d is fixed via c, the curtain d is suspended, and a lock tool f is fixed to one end of the support bar a. Then, cord guide portions g are provided at a required interval from the fixed side of the lock tool f to the opposite side of the support bar, and a bundle j of lifting cords h corresponding to the number of the cord guide portions g is locked. A cord insertion portion k that passes through the tool f and hangs up and down the hose cord h that constitutes the bundle j for each cord guide portion g, and is provided at a required interval in the vertical direction on the rear surface of the curtain d. The lower end of the lifting / lowering cord h is fixed to the lower end side m of the curtain.

  Then, by pulling downward the bundle j of the lifting / lowering cords h inserted through the locking device f, the curtain d can be pulled up to a state where the fold-like folded portions n are stacked as shown in FIGS. In the required lifted state, the lifting / lowering cord h is locked by the locking action of the locking device f, and the curtain d is held in the lifted state.

  Further, in order to give weight to the lower end portion p of the curtain d, a weight bar q is accommodated over the entire width in the accommodating portion p provided at the lower end portion, and the weight bar q is used as a weight under the curtain. In addition, the lower part of the curtain is stretched in the horizontal direction by the weight bar q. However, since the curtain portion located above the weight bar q is not provided with any means for stretching the curtain in the width direction, as shown in FIGS. When pulled up in a stacked state, slack s and wrinkles t occur in the curtain portion u between the cord insertion portions k and k adjacent in the curtain width direction, and the cord insertion portions k are caused by these slack and wrinkles. There is a problem that the linearity of the fold-like folded portion n cannot be ensured, such as the curtain portion u between k and k.

  In view of this, a pull-up curtain device disclosed in Japanese Patent Laid-Open No. 9-154711 has been proposed as ensuring the linearity of the fold-back portion in the curtain pull-up state. As shown in FIG. 49, the pull-up type curtain device v has a bag-like body x containing a rod-like body w extending in the curtain width direction and sewn and fixed in the width direction of the curtain d in a multi-stage parallel state. It was being held in a stretched state. And the cord insertion part k was formed in the surface part of this bag-like body x, and the raising / lowering cord h was penetrated by this code insertion part k.

  However, according to the conventional pull-up type curtain device v, when the bag-like body x is sewn to the curtain, the stitch row y extending in the width direction of the curtain is generated in a multi-stage parallel state. There was a problem that impaired the appearance of the curtain. Further, when the bag-like body x is sewn to the curtain in a slightly inclined state, the cord insertion portions k arranged at a required interval in the length direction of the bag-like body x are arranged obliquely. As a result, when the curtain is pulled up, the shape of the fold-like folded portion becomes distorted, and there is a problem that the appearance of the curtain is impaired. In addition, since the position of the bag-like body x once sewn to the curtain d is fixed, even if it is attempted to change the curtain design in the pulled-up state by changing the vertical position of the bag-like body x, such a request is satisfied. There was a problem that could not be met. In addition, in the conventional pull-up type curtain device v in which the rod-like body can be arranged only in such a predetermined arrangement, wrinkles are generated in, for example, an intermediate portion of the fold-like folded portion when the curtain is pulled up. However, there was no means to eliminate the wrinkles.

  Further, as another means for making the curtain d stretched in the width direction, a pull-up curtain device disclosed in JP-A-2005-334 has been proposed. As shown in FIG. 50, this pull-up type curtain device a1 has a plurality of fitting members b1 attached in the curtain width direction, and a rod-like object c1 is detachably attached via the fitting member b1, and the fitting is performed. A configuration is adopted in which a stopper member d1 that prevents the member b1 from sliding in the center of the curtain is attached to the rod-like object c1 so as to engage with the fitting members b11 and b11 at both outer ends. As a result, tension is applied in the left-right direction between the fitting members b11, b11 at both outer ends as viewed in the curtain width direction, and the curtain is stretched in the width direction at this portion e1, and the fold-like folded portion is formed. It prevents the occurrence of slack and wrinkles and ensures the linearity of the fold-back portion.

  However, when the pull-up curtain device a1 is used, since the fitting members b11 and b11 at both ends in the curtain width direction are set to be inward of the curtain outer edges f1 and f1, the fitting of the outer end is performed. The curtain portion g1 existing outside the combined members b11 and b11 is not in a state of being stretched by the rod-like object c1. Therefore, when the curtain d is pulled up, for example, a slack h1 and a wrinkle j1 as shown in FIG. 51 are generated in the curtain portions g1 and g1 existing outside the fitting members b11 and b11 at both ends, and the curtain width direction is thus increased. The linearity of the fold-back portion k1 is not ensured over the whole, and there is a problem that impairs the appearance of the curtain in the raised state. In the case of such a pull-up curtain, the curtain raising / lowering operation is repeated, so that the stopper member d1 may move in the center of the curtain as shown by an arrow in FIG. In this case, since the tensioned state between the fitting members b11 and b11 at both ends is released, there is a problem that slack and wrinkles are generated in the fold-like folded portion k1 formed by raising the curtain. .

  Further, even when the pull-up type curtain device a1 is used, since the fitting member attached to the curtain cannot be changed in the vertical direction, the vertical design of the fitting member b1 is changed to change the raised curtain design. Even when trying to do so, there was a problem that the request could not be met. In addition, in the conventional pull-up type curtain device in which the rod-like body can be arranged only in such a predetermined arrangement, when the curtain is lifted, wrinkles are generated, for example, in the middle portion of the fold-like folded portion. But there was no way to eliminate the wrinkles.

In addition, when at least the entrance portion of the insertion portion of the intermediate holding tape is enlarged and formed in a tunnel shape or the like, the elastic bar can be easily inserted into the insertion portion.

(5) When the end holding tape is provided with an attachment portion protruding toward the inside of the curtain, and the end holding tape is attached to the curtain body only by sewing or the like only at the attachment portion, The storage bag portion can be released from the curtain body. Therefore, even if the tape base material constituting the storage bag portion swells to the back side, the swelled portion makes the front surface of the curtain body stand out. There is no bulge and deformation, so the front of the curtain body has a more natural appearance.

  Further, when the attachment portion accommodates the side end portion of the elastic bar in the accommodation bag portion, the attachment portion functions as a guide for the tip of the elastic bar, and accordingly, the elastic bar is caught in the accommodation bag portion. Easy to accommodate.

(6) When the intermediate holding tape is formed with insertion portions on both sides of the tape base material, and the space between the insertion portions is an attachment portion with respect to the curtain body, the elastic bar is stably held by the right and left insertion portions. Can hold. In addition, since the insertion part is separated from the curtain body, even if the tape base material constituting the insertion part swells to the back side, the swelled part makes the front surface of the curtain body stand out. There is no bulge and deformation, so the front of the curtain body has a more natural appearance.

  In addition, when both end portions of the tape base material constituting the intermediate holding tape are guide piece portions, the guide piece portion and the attachment portion are elastically inserted when the elastic bar is inserted into the left and right insertion portions. It functions as a guide for the tip of the bar, and therefore it is easy to insert the elastic bar without being caught by the left and right insertion parts.

(7) When the pull-up curtain device according to the present invention is configured by arranging the elastic bar in a horizontal state directly below the cord insertion portion, the elastic bar acts on the elastic bar at the lower portion of the cord insertion portion. As a result, the curtain body is stretched in the width direction, so that a fold-like fold having a linear shape can be formed more beautifully.

The lateral width L11 is 7 mm, the maximum height L12 of the storage bag portion 55 is 2 mm, the width between the adjacent storage bag portions 55 and 55 (the width of the partition edge 51) L13 is 1 mm, and the attachment portion 46 The width L14 is set to 6 mm. Therefore, in the holding tape 20 at the end portion thus dimensioned, the distance L15 between the central axes 59 and 59 of the bag bottom portions 55 and 55 adjacent to each other is 8 mm.

  When attaching the intermediate holding tape 19 having the above configuration to the rear surface 11 of the curtain body 10, as shown in FIGS. 5 and 8A, the back surface 60 of the tape base material 47 is placed on the curtain body 10. The tape base material 47 is brought into a contact state in the vertical direction on both side portions 12a, 12a and the central portion 12b of the rear surface 11, and the attachment portion 41 is placed on the curtain body 10 along its longitudinal center line. Sewing 58 is performed. As a result, as shown in FIG. 8B, the intermediate holding tape 19 is attached to the rear surface 11 of the curtain body 10 only by forming one stitch row 62 on the front surface 61 of the curtain body 10. . By this attachment, the insertion portions 35 are arranged in parallel in the vertical direction at intervals of 8 mm.

  Further, when attaching the holding tape 20 at the end of the above configuration to the rear surface 11 of the curtain body 10, as shown in FIGS. 5 and 9, the back surface 63 of the tape base material 47 is attached to the rear surface of the curtain body. In the left and right outer edge portions 15 and 15, the tape base material 47 is brought into a contact state in the vertical direction. At this time, the outer edge 65 of the bag forming portion 45 may be aligned with the curtain outer edge 43. However, in this embodiment, the outer edge 65 of the bag forming portion 45 is about 5 mm longer than the curtain outer edge 43. Retracted inward (center of curtain). In this state, the attachment portion 46 is sewn 58 to the curtain body 10 along the longitudinal center line thereof, so that the attachment portion 46 is attached to the rear surface 11 of the curtain body 10. By this attachment, the storage bag portions 55 are juxtaposed in the vertical direction at intervals of 8 mm. A portion (a portion having a width of 5 mm) protruding from the outer edge 65 of the bag forming portion 45 becomes a cover portion 66. The width L16 of the cover portion 66 may be set smaller as long as it can cover a later-described bulging and deformed portion 79 (FIG. 14).

  In this way, by attaching the intermediate holding tapes 19, 19, 19 and the holding tapes 20, 20 at the ends to the curtain body 10, the pull-up type curtain 6 is configured. In order to configure the pull-up curtain 1 using the pull-up curtain 6, as shown in FIGS. 10 to 11, the three intermediate holding tapes 19, 19, 19 attached as described above are attached. The ring-shaped member 67 hooks the hook 69 on the insertion portion 35 at the same height position of the portion near the lower end (for example, the portion located about 12 cm above the lower end 64 of the curtain body 10). It is attached. Further, each of the three intermediate holding tapes 19, 19, 19 has a plurality of stages (for example, with a ring-shaped member 67, 67, 67 attached in this way upward at a required interval with the base end as an example. The ring-shaped member 67 having the same structure as described above hooks the hook 69 on the insertion portion 35 at approximately the same height position at intervals of about 15 to 40 cm (in this embodiment, three steps at intervals of about 24 cm). Installed by wearing. The upper three-stage ring-shaped members 67, 67, 67 constitute a cord insertion part 70 for inserting the lifting / lowering cord 3.

  Then, as shown in FIG. 11, the elastic bars (for example, about 3 mm in diameter) are inserted into the insertion portions 35a, 35a, 35a, 35a, 35a, 35a located immediately below the lowermost ring-shaped members 67a, 67a, 67a. ) 9 is inserted in a cramped state. This insertion can be easily performed because each insertion portion 35a is enlarged in a tunnel shape as described above (the inlet portion 71 (FIG. 6D) is enlarged). Further, in this embodiment, since both end portions of the tape base material 31 constituting the intermediate holding tape 19 are guide piece portions 39 and 39 (FIG. 6B), the elastic bar 9 is moved to the left and right. The guide piece portion 39 and the attachment portion 41 function as a guide for the tip of the elastic bar 9 when being inserted through the insertion portions 35, 35. Therefore, it is easy to insert the elastic bar 9 without being caught by the left and right insertion portions 35, 35. With the elastic bar 9 inserted through the insertion portion 35 in this way, the insertion portion 35 is enlarged as shown in FIG. 12, and in this enlarged state, the tape base material 31 is indicated by reference numeral 73 in FIG. So that it swells on its back side.

  The elastic bar 9 inserted in this manner is in a horizontal state, and as shown in FIGS. 11 and 14, the left and right side end portions 16 and 16 are cramped by the left and right accommodation bag portions 55 and 55. Be contained. The left and right accommodation bag portions 55a, 55a selected at this time are on substantially the extension line of the elastic bar 9 exhibiting the horizontal state. The side end portion 16 is accommodated in the accommodation bag portion 55a because the accommodation bag portion 55 is enlarged by the arcuate bulge of the holding tape portion 49 (the opening end 75 (FIG. 7) is enlarged). ) Can be done relatively easily. In this embodiment, the attachment portion 46 protrudes from the bag forming portion 45 toward the inside of the curtain. Therefore, when the side end portion 16 of the elastic bar is accommodated in the accommodation bag portion 55, the attachment portion 46 is removed. The wearing portion 46 functions as a guide for the tip 72 of the elastic bar 9. Therefore, the side end portion 16 can be easily accommodated without being caught in the accommodation bag portion 55. In a state where the elastic bar 9 is accommodated in the accommodation bag portion 55a, the accommodation bag portion 55a expands as shown in FIG. 13, and in this enlarged state, the tape base material 47 is denoted by reference numeral 76 in FIG. So that it swells on its back side.

  In the present embodiment, the insertion portion 35 and the storage bag portion 55 are juxtaposed in the vertical direction at a small interval of 8 mm as described above, so that the elastic bar 9 is connected to each insertion portion 35a, 35a, 35a, The elastic bar 9 is in a horizontal state with the left and right side end portions 16 and 16 being accommodated in the left and right accommodation bag portions 55a and 55a (FIGS. 11 and 13). It can be presented.

  Here, the overall length of the elastic bar 9 is set to be much longer (in the present embodiment, about 5 mm longer) than the length between the bag bottom portions 53, 53 of the left and right accommodation bag portions 55a, 55a. In a state where the left and right side end portions 16 and 16 of the bar 9 are accommodated in the left and right accommodation bag portions 55a and 55a, the outer ends 77 and 77 of the left and right side end portions 16 and 16 are as shown in FIG. The left and right bag bottom portions 53 and 53 are elastically pressed outward, and the bag bottom portions 53 and 53 are bulged outward and deformed.

  Thereby, as shown in FIG. 14, the curtain main body 10 is in a state of being stretched in a horizontal direction (a state in which tension is applied) by the elastic tensioning action of the elastic bar 9. In such a stretched state, the bag bottoms 53 and 53 are bulged and deformed outward as described above, but the bulged and deformed portions 79 and 79 are as small as about 2.5 mm. This is in a state of being covered with the cover portions 66 and 66. Therefore, the bulging and deformed portions 79 and 79 cannot be seen from the front surface 61 side of the curtain body 10.

  In the present embodiment, as described above, the holding tape 20 at the end is sewn to the curtain body 10 at the attachment portion 46 where the storage bag portion 55 is not provided. As shown in FIG. 15, the storage bag portion 55 is separated from the curtain body 10. Therefore, even if the tape base material 47 constituting the containing bag portion 55 swells to the back side as shown in FIG. 13, the swelled portion 76 swells to make the front surface 61 of the curtain body 10 conspicuous. The front surface 61 of the curtain body 10 has a natural appearance without being deformed.

  As shown in FIG. 16, if the holding tape 20 at the end is sewn 58 to the curtain body 10 also at the outer edge 81 of the bag forming portion 45 (the present invention does not include such an embodiment). The bulging portion 76 locally presses the curtain main body 10 to produce a clear bulging deformation 82 on the front surface 61 of the curtain main body 10 as shown in FIG. This is not preferable because the appearance of the glass is impaired. When the bag forming portion 45 is also sewn to the curtain body 10 at the outer edge 81, the outer end 77 of the side end portion 16 of the elastic bar 9 elastically presses the bag bottom 53 outward. In addition, the bag bottom 53 is not simply expanded and deformed as described above, but the curtain outer edge portion 44 is forcibly deformed outward as indicated by reference numeral 83 in FIG. In addition to the problem of natural deformation, it is not preferable that the curtain body 10 is thin because the curtain body 10 may be damaged.

  In this embodiment, as described above, when the intermediate holding tape 19 is attached to the curtain body 10, the curtain body 10 is sewn at the attachment portion 41 between the left and right insertion portions 35, 35. Since the structure to wear is employ | adopted, this insertion part 35 and 35 is released | separated from the curtain main body 10. FIG. Therefore, even if the tape base material 31 constituting the insertion portion 35 swells to the back surface side as shown in FIG. 12, the swelled portions 73 and 73 stand out from the front surface 61 of the curtain body 10. The front surface 61 of the curtain body 10 has a natural appearance without being bulged and deformed.

  As shown in FIGS. 10 and 18, the insertion portions 35 b, 35 b, 35 b, 35 b, 35 b, and 35 b that are located directly below the second-stage ring-shaped members 67 b, 67 b, 67 b from the bottom are also shown in FIGS. In the same manner as described above, the elastic bar 9 is inserted horizontally, and the left and right side end portions 16 and 16 of the elastic bar 9 are accommodated in the left and right accommodation bag portions 55b and 55b.

  Similarly, the elastic bars are also inserted in the insertion portions 35, 35, 35, 35, 35, 35 located immediately below the third-stage and fourth-stage ring members 67, 67, 67 from the bottom in the same manner as described above. 9 is inserted in a horizontal state, and the left and right side end portions 16 and 16 of the elastic bar 9 are accommodated in the accommodation bag portions 55 and 55 facing left and right.

  Further, as shown in FIGS. 10 and 19, the insertion portions 35c, 35c, 35c, 35c, 35c, and 35c having substantially the same height at the center portion between the upper and lower ring-shaped members 67 and 67 are also the same as described above. Thus, the elastic bar 9 is inserted in a horizontal state, and the left and right side end portions 16 and 16 of the elastic bar 9 are received in the left and right receiving bag portions 55c and 55c in the same manner as described above. In addition, as shown in FIGS. 10 and 20, the elastic bar 9 is inserted horizontally into the insertion portions 35 d, 35 d, 35 d, 35 d, 35 d, and 35 d having substantially the same height located near the upper end of the curtain body 10. The left and right side end portions 16 and 16 of the elastic bar 9 are accommodated in the accommodation bag portions 55d and 55d which are opposed to the left and right.

  In order to configure the pull-up curtain device 2 using the pull-up curtain 1 configured by attaching the ring-shaped member 67 and the elastic bar 9 to the pull-up curtain 6, for example, as shown in FIGS. Further, for example, a planar fastener 86 is provided on a room-side surface portion of a box-shaped support bar 85 provided along the upper edge of the window opening, and a lock 87 is fixed to one end of the support bar 85, and the lock Cord guide portions 89 are provided at a required interval from the fixed side of the tool 87 toward the opposite side of the support bar 85. In the present embodiment, the cord guiding portion 89 is arranged on both end sides of the support bar 85 according to the arrangement of the three intermediate holding tapes 19, 19, 19 attached to the curtain body 10 in the vertical direction. It is provided at three places in the central part. The pull-up curtain 1 is supported by the hook-and-loop curtain 1 provided on the upper end edge of the pull-up curtain 1 by engaging the flat fastener 86 provided on the support bar 85. The bar 85 is suspended. Further, a bundle 90 of three lifting / lowering cords 3, 3 and 3 corresponding to the number of the three cord guiding portions 89, 89 and 89 is passed through the locking device 87, and as shown in FIG. The cords 3, 3, 3 are hung for each of the code guide portions 89, 89, 89. By sequentially inserting the cord insertion portions 70, 70, 70, and connecting the lower end 91 of the lifting / lowering cord 3 to the attachment piece 92 hooked to the ring-shaped member 67a at the lowermost end, as shown in FIG. The lower end 91 is fixed to the lower end side of the curtain body 10. Thereby, the pull-up type curtain apparatus 2 using the said pull-up type curtain 1 is comprised.

  In the pulling-up type curtain device 2 having such a configuration, the pulling-up type curtain 1 is moved to the direction shown in FIGS. As shown, the fold-like folded portion 5 can be pulled up in a stacked state, and the liftable curtain 1 is pulled up by locking the elevating cord 3 by the locking action of the locking device 87 in the required lifted state. Can be held in a state.

  Thus, in the state where the curtain is pulled up, the elastic bar 9 arranged as described above contributes to ensure the linearity of the fold-like folded portion 5. More specifically, the curtain body 10 is stretched in the horizontal direction by the elastic tensioning action of the elastic bar 9 at the portion where each of the elastic bars 9 is disposed. However, in the state in which the curtain body 10 is pulled up, as shown in FIGS. 2 to 3 and FIG. 22, the elastic bar 9 located immediately below the cord insertion portion 70 has the fold-like folded portion formed by lifting. 5, the upper edge portion 93 is stretched in the horizontal direction by the elastic tensioning action of the elastic bar 9. Therefore, in the portion between the cord insertion portions 70 and 70 adjacent in the curtain width direction, the slack s and wrinkles t as shown in FIGS. 47 to 48 described in relation to the conventional pull-up curtain, as shown in FIG. Thus, the slackness h1 and the wrinkle j1 are not generated, and the linearity of the upper edge portion 93 can be secured. In this embodiment, the elastic bar 9 is also provided at the central portion between the upper and lower adjacent cord insertion portions 70, so that the elastic bar 9 is the weight of the lower end portion 95 of the fold-like folded portion 5. It becomes. However, since the elastic bar 9 is in a state where the lower end portion 95 is stretched in the horizontal direction, the lower end portion 95 of the fold-like folded portion 5 is not loosened or wrinkled, as shown in FIG. The linearity of the lower end portion 95 is also ensured. For this reason, the fold-like folded portion 5 is curved with a natural curve that looks good and hangs down. In this embodiment, it hangs down about 12 cm.

  As described above, since the bag bottom portion 53 bulging and deforming outward does not protrude from the curtain outer edges 43 and 43, the entire elastic bar 9 is covered with the curtain body 10 from the front side of the curtain body 10. (Fig. 14), and the appearance of the pull-up curtain 1 from the front side is not damaged by the elastic bar 9. However, in this embodiment, the storage bag portion 55 provided on the holding tape 20 at the end is made free from the curtain body 10 and the insertion provided on both sides of the intermediate holding tape 19 is used. The portions 35 and 35 are also free from the curtain body 10. Therefore, in a state where the side end portion 16 of the elastic bar 9 is accommodated in the accommodation bag portion 55, the accommodation bag portion 55 is inflated as shown in FIG. 13, and the elastic bar 9 is inserted into the insertion portion 35. Even when the insertion part 35 is in a swelled state as shown in FIG. 12, these do not swell and deform the curtain body 10 in a conspicuous state, so that the storage bag part 55 and the insertion part 35 in the swelled state There is no fear of damaging the appearance of the pull-up curtain 1 from the front side.

  In the pull-up curtain 1 having such a configuration, the elastic bar 9 is detachable. Therefore, when the curtain is washed, the elastic bar 9 can be removed.

  In the present embodiment, as shown in FIGS. 1, 10, 11, and 18, since the elastic bar 9 is inserted into the insertion portions 35 and 35 that are located directly below the ring-shaped members 67, There is an advantage that the pleated folded portion 5 having a shape can be formed more beautifully. For example, as shown in FIG. 23, when the elastic bar 9 is inserted through the insertion portions 35, 35 positioned immediately above each ring-shaped member 67, when the ring-shaped member 67 is lifted by lifting the lifting / lowering cord 3, There is a case where the elastic tensioning action of the elastic bar 9 does not reach the lower portion of the ring-shaped member 67 so much that the both-side curtain portions 96, 96 on the lower side of the raised ring-shaped member 67 are loosened by their own weight. In some cases, the wrinkle 97 is generated in the shape of an eight. In particular, when the curtain body 10 is a thin ground with low rigidity, such wrinkles are likely to occur. On the other hand, as shown in FIGS. 2 and 10, when the elastic bar 9 is inserted through the insertion portions 35, 35 located immediately below each ring-shaped member 67, the elastic bar 9 is elastically stretched, The curtain body 10 is stretched in the width direction at the lower portion 94 (FIG. 2) of the ring-shaped member 67. Accordingly, no wrinkles are generated in the shape of an eight character as described above, and the curtain body 10 is beautifully bent into an inverted U shape 98 at the mounting height position of the ring-shaped member 67. Is formed more beautifully.

  The present invention is by no means limited to those shown in the above-described embodiments, and it goes without saying that various design changes can be made within the scope of the claims. One example is as follows.

(1) In the pull-up curtain 1, the portion where the elastic bar 9 is disposed is from the viewpoint of favorably ensuring the linearity of the fold-back portion 5 formed when the pull-up curtain 1 is pulled up. In addition to being set at the same height as the cord insertion portion 70 or directly above or directly below it, it is preferable to set it at the center portion between the upper and lower cord insertion portions, but the formed fold-like folded portion 5 In the case where the linearity is not so hindered, the elastic bar may not be provided at the central portion.

  As for the curtain design in the raised state of the pull-up curtain 1, it is desired to ensure the linearity of the fold-like folded portion only in the lower part, only the middle part or only the upper part of the curtain body 10, but other parts. Then you may want to cause slack and wrinkles. In such a case, the elastic bar 9 may be provided only in a portion where it is desired to ensure the linearity of the fold-like folded portion, and the elastic bar 9 may not be provided in other portions.

  In these cases, the weight bar 25 may not be provided at the lower end portion of the curtain body 10.

  Further, for example, when a perforated decorative portion 99 or a specific patterned decorative portion 99 is provided in a part of the curtain body 10, it is not desired that these decorative portions 99 be loosened or wrinkled even when the curtain main body 10 is pulled up. There is a case. In such a case, for example, as shown in FIG. 24, by arranging the elastic bars 9, 9 above and below the decorative portion 99, the upper and lower elastic bars 9, 9 can be stretched. It becomes possible to keep the shape of the decoration part 99 and the form of the handle clear.

  In short, the elastic bar 9 is disposed as required by selecting a portion where it is not desired to generate slack or wrinkles on the front surface of the curtain body 10. And the end holding | maintenance part 17 and the intermediate | middle holding | maintenance part 13 are provided in the said curtain main body 10 according to such a purpose.

(2) The end holding portion 17 provided on the left and right outer edge portions 15, 15 of the curtain body 10 can essentially hold the side end portion 16 of the elastic bar 9 in a detachable manner, and in the curtain width direction.
