Description

The present invention relates to a holding member for a flat curtain, and also to a flat curtain device that uses the same.

Patent Documents 1 and 2 disclose examples of flat curtains that are formed with waves of alternating peaks and valleys.

The flat curtain disclosed in Patent Document 1 has multiple hanging devices attached at a specified interval along the upper edge of the curtain fabric in order to form a natural-looking wave when hung, and has alternating connected sections where adjacent hanging devices are connected with connectors and non-connected sections where adjacent hanging devices are not connected. One form of flat curtain disclosed in Patent Document 2 employs a configuration in which the fixed rod of the curtain hook is inserted into the insertion hole protruding portion of the fabric width adjustment band in order to freely set the size of the waves formed in the curtain fabric and the width of the curtain fabric itself.
However, the flat curtains disclosed in Patent Documents 1 and 2 have the following problems:

(1) In the flat curtain disclosed in Patent Document 1, adjacent hanging tools are connected with connectors, so that between connected sections where adjacent hanging tools are connected with connectors, there are non-connected sections where adjacent hanging tools are not connected, and in these non-connected sections, the curve of the upper edge of the curtain fabric becomes stretched out, which may result in the failure to form the "natural-looking wave" that Patent Document 1 aims to achieve.

(2) Furthermore, with the flat curtain disclosed in Patent Document 1, adjacent hanging devices are connected with a connector, which may impede the running of the runner. Regarding this point, paragraph 0017 of the specification of Patent Document 1 presupposes that "the body of the hanging device rotates when pulled by the connector," and states that "with the flat curtain of the present invention, by making the body of the hanging device rotatable relative to the hook body, even if the body of the hanging device rotates when pulled by the connector, or even if the body of the hanging device rotates to match the upper edge of the curved curtain fabric, no rotational force acts on the runner, and the running of the runner is not impeded."

(3) As a means for determining the shape of the wave, in the flat curtain disclosed in Patent Document 1, adjacent hanging devices are connected with a connector, and in the flat curtain disclosed in Patent Document 2, the fixed rod of the curtain hook is inserted into the protruding portion for the insertion hole of the fabric width adjustment band. Therefore, in Patent Documents 1 and 2, there is a problem that the shape of the curtain wave is restricted by the attachment position of the curtain hook, and there are restrictions on the shape of the wave that can be formed on the curtain.

(4) In the flat curtains disclosed in Patent Documents 1 and 2, the connector (Patent Document 1) and fabric width adjustment band (Patent Document 2) were attached to the hanging hook in order to form waves in the flat curtain. Therefore, when the hanging hook was removed from the flat curtain when washing the curtain, the shape of the waves was also lost. This caused a problem in that after washing, the pitch had to be set as required and the waves had to be re-formed, which was a tedious task.

FIG.

In Figures 1 and 2, the flat curtain retaining member (hereinafter also referred to as the retaining member) 1 according to the present invention is used to form a flat curtain 6 in which waves 5 are formed with alternating peaks 2 and valleys 3. A flexible linear member 10 is arranged in the extension direction of the rear surface 9 of the upper end portion 7 of the flat curtain 6, and fastening portions 12 are provided at required intervals on the rear surface portion 11 of the valleys 3 (part of the rear surface 9).

Figures 1 and 3 show a flat curtain device 18 constructed by hanging the flat curtain 6 via a curtain hook 13 attached to the rear portion 9 on a hanging ring 17 of a runner 16 that slides along the length of a curtain rail 15.

In this embodiment, as shown in Figures 1-2 and 4, the linear member 10 is a fixed-length linear member 10a set to a required length, and the fastening portion 12 is provided at both end portions 19, 19 as viewed in the extension direction F1 of the fixed-length linear member 10a. The fastening portion 12 is configured with a first engaging portion 21 that engages with a second engaging portion 20 provided on the rear surface portion 9 and is fastened to the rear surface portion 9. This will be described in detail below.

The flat curtain 6 is constructed by abutting a fastening tape 26, for example as shown in FIG. 5 or FIG. 6, against the main body rear surface 25 of the upper edge portion 23 of the curtain main body 22 as shown in FIG. 1 and FIG. 3, and sewing the upper and lower edges of the fastening tape 26 to the upper edge portion 23. The fastening tape 26 sewn in this way constitutes the upper end portion 7 of the flat curtain 6, and also contributes to improving the rigidity of the upper end portion 7 and further improving the shape stability of the wave 5.

As shown in Figures 1, 3, 5 and 6, the fastening tape 26 is formed as a woven or knitted tape of equal width on the upper and lower edge sides 32, 33 of the surface 31 of a tape substrate 30. The upper and lower hook end insertion sections 37, 39 for inserting the upper and lower hook end sections 35, 36 of the curtain hook 13 are arranged in a vertically opposed state on the upper and lower edge sides 32, 33 of the surface 31 of the tape substrate 30. The upper and lower hook end insertion sections 37, 39 have the same configuration.

An example of the method for forming the upper and lower hook end portion inserts 37, 39 is described with reference to Figures 5 and 6. On the surface 31 of the tape base material 30, a hook end portion insert forming tape 40 is placed, extending in the length direction of the tape base material 30, and the insert forming tape 40 is integrated with the tape base material 30 at intervals of 10 to 20 mm in the length direction by weaving, knitting, welding, sewing, etc., for example by weaving, to form upper and lower opposing partition edges 41, 41. In this way, the upper and lower hook end portion inserts 37, 39 can be formed between the adjacent partition edges 41, 41, the tape base material 30, and the insert forming tape 40.

The tape base material 30 is sewn to the rear surface portion 25 of the curtain body 22 with its back surface 42 in contact with the rear surface portion 25, thereby forming the rear surface portion 9 (Figs. 1 and 3). As shown in Figs. 1 and 3, the upper and lower hook end portions 35, 36 of the curtain hook 13, which is hung on the hanging ring 17 of the runner 16 slidably suspended from the curtain rail 15, are inserted into the required set of the upper and lower hook end portion insertion portions 37, 39, thereby attaching the curtain hook 13 to the rear surface portion 9 of the flat curtain 6 at the required intervals.

Figure 5 shows the left-right insertion portion 44 as the second engagement portion 20, with the left and right ends open. The left-right insertion portion 44 is arranged in parallel at a required interval in the extension direction of the tape substrate 30 in the longitudinal center portion 38 of the surface 31 of the tape substrate 30. Figure 5 (B) shows an example of the configuration of the left-right insertion portion 44, which is composed of multiple floating threads 46, for example 2 to 10, whose both ends 45, 45 are attached to the tape substrate 30 and which are in a floating state on the surface 31 of the tape substrate 30. The length in the vertical direction is set as required depending on the width of the linear member 10, for example 10 to 20 mm, and in this embodiment it is set to 18 mm.

Figure 6 shows the vertical insertion portions 43, 43 as the second engagement portion 20, with the upper and lower ends open. The vertical insertion portions 43, 43 are arranged side by side at a required interval in the extension direction of the tape base material 30, facing each other vertically, at the upper and lower parts of the central portion 38 that extends in the length direction of the surface 31 of the tape base material 30. In this embodiment, they are arranged side by side at a required interval in the extension direction F1 between the upper and lower hook end portion insertion portions 37, 39.

Figure 6 shows an example of how the set of vertical insertion sections 43, 43 is formed. The insertion section forming tapes 48, 48 are arranged extending in the extension direction F1 at the upper and lower parts of the central portion 38 of the surface 31 of the tape base material 30, respectively. They are integrated with the tape base material 30 by weaving at intervals of 5 to 10 mm in the length direction to form partition edges 47, and the vertical insertion sections 43 are formed between adjacent partition edges 47, 47, the tape base material 30, and the insertion section forming tapes 48.

In this embodiment, the linear member 10 (Fig. 4) is configured as the fixed-length linear member 10a, which is configured as a woven or knitted tape having a width of 5 to 30 mm, a length of 60 to 300 mm (preferably 80 to 150 mm, and 120 mm in this embodiment), and a thickness of 0.5 to 1.5 mm. The fastening portion 12 as the first engaging portion 21 provided at both end portions 19, 19 as viewed in the extension direction F1 is configured as a synthetic resin shaft body 51 (the first engaging portion 21) having a protruding shaft portion 50 that protrudes in a direction perpendicular to the extension direction of the fixed-length linear member 10a at the opposing upper and lower side edges 49a, 49b of the fixed-length linear member 10a, as shown in Fig. 4. The shaft 51 has an elliptical cross section with a major axis of 3.3 mm and a minor axis of 2.5 mm, and is set to a total length of 25 mm. Each of the end portions 19, 19 of the fixed-length linear member 10a is embedded in the shaft 51 during injection molding. In FIG. 4, the end portion 19 is disposed in the minor axis direction of the shaft 51.

When the second engagement portion 20 is configured with the left-right insertion portion 44 (FIG. 5(A)), the shaft body 51 is inserted into the left-right insertion portion 44 provided on the rear surface portion 9, and as shown by the dashed line in FIG. 5(B), the protruding shaft portions 50, 50 engage in abutting contact with the outer edges (upper and lower edges) 54, 54 of the left-right insertion portion 44 when viewed in the left-right direction, preventing the shaft body 51 from moving inward in the left-right direction F2, whereby the fastening portion (first engagement portion 21) 12 as the shaft body 51 is fastened to the second engagement portion 20 as the left-right insertion portion 44.

In addition, when the second engagement portion 20 is configured with the vertical insertion portions 43, 43, as shown in FIG. 6, the upper and lower protruding shaft portions (the first engagement portions) 50, 50 of the shaft body 51 are inserted or inserted into the vertical insertion portions 43, 43 (the second engagement portions 20, 20) provided on the rear surface portion 9, so that the upper and lower protruding shaft portions (parts of the fastening portions 12, 12) 50, 50 are fastened to the rear surface portion 9.

In part A shown in FIG. 6, the linear member 10 is arranged on the rear surface 9 so as to extend in the extension direction of the rear surface 9, and the two protruding shaft portions 50, 50 of the shaft body 51 are inserted into the vertical insertion portions 43, 43, thereby fastening the fastening portion 12 to the rear surface 9. Also, in part B shown in FIG. 6, the linear member 10 is arranged in a similar manner, and the protruding shaft portions 50, 50 of the shaft body 51 are inserted into the vertical insertion portions 43, 43, thereby fastening the fastening portion 12 to the rear surface 9. In order to achieve such an inserted state, the vertical length of the vertical insertion portions 43, 43 is set short, or the length of the upper and lower protruding shaft portions 50, 50 is set long.

The insertion state or the insertion state should be a tight fit state in which the both end protruding shaft portions 50, 50 do not easily slip out of the vertical insertion portions 43, 43. For this reason, the gap between the adjacent partition edges 47, 47 of the vertical insertion portions 43, 43 is made small so that the both end protruding shaft portions 50, 50 are inserted or passed through the vertical insertion portions 43, 43 in a cramped manner.

Figures 7 to 8 show another embodiment of the flat curtain retaining member 1, which is used to form the flat curtain 6 having waves 5 formed by alternating peaks 2 and valleys 3. A flexible linear member 10 is disposed in the extension direction of the rear surface 9 of the upper end portion 7 of the flat curtain 6, and a fastening portion 12 is provided which is fastened to the rear surface portion 11 (Figure 1) of the valleys 3. The linear member 10 may be tape-shaped or string-shaped. In Figures 7 to 8, it is string-shaped. The fastening portion 12 is composed of a fastening member 53 which protrudes in the downward direction F3 perpendicular to the extension direction F1 of the linear member 10 and is inserted downward through the vertical insertion portion 43 (Figures 6 and 7 (B)). The fastening member 53 is provided with a slip-out prevention engagement portion 56 that, when viewed in the inserted state, engages with the leading edge portion (the adjacent partition edges 41, 41) 55, 55 of the vertical insertion portion 43 as viewed in the insertion direction to prevent the fastening member 53 from moving in the slip-out direction (the direction opposite to the insertion direction).

In FIG. 9, the fastening portion 12 protrudes in an upward direction F4 perpendicular to the extension direction F1 of the linear member 10. Such upward protrusion can be obtained by turning the linear member 10 upside down. In this case, the fastening member 53 is inserted into the vertical insertion portion 43 in an upward direction perpendicular to the extension direction F1. This provides the same effect as when the fastening member 53 is inserted downward, and prevents the fastening member 53 from moving in the removal direction (the opposite direction to the insertion direction).

The structure of the fastening member 53 as the first engaging portion 21 provided at both ends of the string-like linear member 10 will be described in more detail with reference to Figures 7-8. The fastening member 53 has an arrow-shaped plate shape formed by protruding a triangular plate portion 59 from the tip of a rectangular plate portion 57 that can be inserted into the vertical insertion portion 43, and is integrated with the end portion 19 of the linear member 10 by injection molding. The base end side side portions 60, 60 of the triangular plate portion 59 constitute the slip-out prevention engaging portions 56, 56, and protrude from both sides of the tip of the rectangular plate portion 57. In addition, a split groove 58 is provided between the triangular plate portion 59 and the rectangular plate portion 57, opening at the center of the tip of the triangular plate portion 59.

When the fastening member 53 is inserted into the vertical insertion portion 43 from its tip side, the fastening member 53 elastically reduces the groove width of the split groove 58 as necessary, and the triangular plate-shaped portion 57 pushes the vertical insertion portion 43 wide and protrudes from its tip, and the engagement step portions 61, 61 on both sides 60, 60 of the triangular plate-shaped portion 59 engage with both end edges (the adjacent partition edges) 41, 41 on the tip side of the vertical insertion portion 43. This prevents the fastening member 53 from moving in the removal direction (the opposite direction to the insertion direction), and the fastening member 53 is fastened to the rear side portion 11 of the valley portion 3.

Figures 10 (A) and (B) show other aspects of the flat curtain retaining member 1, which is used to form the flat curtain 6 in which waves 5 are formed by alternating peaks 2 and valleys 3. The retaining member 1 is a linear member 10 as a fixed-length linear member 10a having flexibility arranged in the extension direction of the rear surface portion 9 of the upper end portion 7 of the flat curtain 6, and is provided with a fastening portion 12 consisting of a loop-shaped engaging piece 63 (the first engaging portion 21) that is fastened to the rear surface portion 11 (Figure 1) of the valley portion 3. Figure 10 (B) shows a state in which the fastening portion 12 is fastened to, for example, the vertical insertion portion 43 using a hook member 64, for example an S-shaped ring 64a, which is hooked to the vertical insertion portion 43. Figure 10 (C) shows another embodiment of the loop-shaped engagement piece 63, which is configured with floating pieces 66 provided on the surface of a tape-like material 65 at required intervals in the length direction of the tape-like material 65, with both ends connected to the tape-like material so that the middle portion is floating from the tape-like material 65, and the loop-shaped engagement piece 63 is configured by the tape-like material 65 and the floating pieces 66. In this case, as in the above, the fastening portion 12 as the loop-shaped engagement piece 63 can be fastened to the vertical insertion portion 43 using, for example, the S-shaped ring.

In Figures 4(A), 7(A), 8, and 10(A), the flat curtain retaining member 1 shown extended by dashed lines has a long linear member 10. The linear member 10 has a large number of fastening parts 12 at required intervals that are fastened to the rear side part 11 of the valley part 3.

The fastening portion 12 provided on the linear member 10 is fastened to the second engagement portion 20 set at the rear side portion 11 of a specific valley portion 3 selected according to the shape of the wave 5 desired by the user, and is not necessarily fastened to the rear side portion 11 of all valley portions.

When such a long flat curtain holding member 1 is used, there is an effect that the number of operations required to fasten the upper end portion 7 of the flat curtain 6 to the rear surface portion 9 can be reduced compared to when the linear member 10 is of fixed size as described above.

Figures 11 to 13 show other aspects of the flat curtain retaining member 1 according to the present invention, which is used to attach the upper end portion 7 of the flat curtain 6 to the rail body 69 of a rod-shaped curtain rail 67. The curtain retaining member 1 has a flexible linear member 10 arranged vertically at the rear surface portion 9 of the upper end portion 7 of the flat curtain 6, and fastening parts 12 are provided at both ends 70, 71 of the rear surface portion 9 of the flat curtain 6, which are fastened to the rear surface portion 9. With the fastening parts 12, 12 fastened to the rear surface portion 9, the rail body 69 can be held in an inserted state in the insertion holding part 72 (Figures 11 and 12) formed between the rear surface portion 9 and the linear member 10, or in the loop-shaped part 73 (Figure 13) formed by the linear member 10. By holding it in the inserted state, the flat curtain 6 is attached to the rod-shaped curtain rail 67 in a suspended state.

In this embodiment, the linear member 10 is set to a width of 5 to 30 mm and a thickness of 0.5 to 1.5 mm, as described above, and its length is set as required (for example, 120 mm) according to the diameter of the rod-shaped curtain rail 67.

Figures 11 to 13 show an example of the fastening portion 12. The fastening portion 12 is configured in the same manner as in the case of forming the wave 5, for example, and is configured with a shaft body 77 of the same configuration as described above, which has protruding shaft portions 76, 76 that protrude in a direction perpendicular to the extension direction of the linear member 10 at the opposing left and right side edges 75, 75 at the upper and lower ends 70, 71 of the linear member 10. The holding member 1 of this embodiment is used with the linear member 10 of the holding member 1 for forming the flat curtain in the up-down direction instead of the left-right direction as described above.

In the fastening state of the fastening portion 12 shown in Figure 11, the upper and lower shaft bodies 77, 77 are inserted, for example, into the upper and lower hook end portion insertion portions 37, 39 from the inside toward the outside, and the protruding shaft portions 76, 76 are engaged with the leading edge portions (the adjacent partition edges 41, 41) 55, 55 of the hook end portion insertion portions 37, 39 when viewed in the insertion direction. In the fastening state of the fastening portion 12 shown in FIG. 12, the upper and lower shafts 77, 77 (functioning in the same way as the shafts 51, 51) are inserted into the upper and lower hook end portion insertion portions 37, 39 from the outside toward the inside, and the two protruding shafts 76, 76 are engaged with the leading edge portions (the adjacent partition edges 41, 41) 55, 55 of the hook end portion insertion portions 37, 39 when viewed in the insertion direction.

In the fastening state of the fastening portion 12 shown in FIG. 13, the two protruding shaft portions 76, 76 of the upper and lower shaft bodies 77, 77 are both inserted, for example, from the inside to the outside of the upper hook end portion insertion portion 37, and the two protruding shaft portions 76, 76 are engaged with the leading edge portions (the adjacent partition edges 41, 41) 55, 55 of the hook end portion insertion portion 37 as viewed in the insertion direction.

Figures 1 and 2 show an example of a flat curtain device 18 using a flat curtain 6 formed with a wave 5 in which the peaks 2 and valleys 3 are alternately connected, and the wave 5 is constructed using a required number of the holding members 1 shown in the example. Both of these holding members 1 are used to form a flat curtain 6 formed with a wave 5 in which the peaks 2 and valleys 3 are alternately connected, and the adjacent fastening parts 12, 12 of the holding member 1 are fastened to the rear side parts 11, 11 of the adjacent valleys 3, 3 (in Figure 1, the parts near the bottom end parts 3a of the valleys 3). As a result, the base end width (pitch) of the peaks 2, 2 is regulated by the length between the fastening parts 12, 12 of the linear member 10.

Here, the main wave configuration elements that determine the configuration of the wave 5 will be described with reference to FIG. 2 and FIGS.
(1) The rear surface portions 11, 11 of the adjacent valley portions 3, 3 are all or partly connected to each other by the holding member 1 (see Figs. 2 and 15).
(2) The wave shape is determined by the width (pitch P) of the peaks 2 of the wave 5 and the peak height H (see FIGS. 14A and 14B).
(3) By setting the position of the second engagement portion 20 on the rear surface portion 9 as required, the height H of the peak portion 2 can be changed while keeping the pitch P constant (see FIG. 14A). For example, the height of the peak portion 2 can be changed to H1 or H2 while keeping the pitch constant.
(4) By setting the position of the second engagement portion 20 on the rear surface portion 9 as required, the pitch P can be changed while keeping the height H of the peaks 2 constant (see FIG. 14B). For example, the pitch P can be changed to a pitch P1 or a pitch P2 while keeping the height of the peaks 2 constant.
(5) The fastening portion 12 provided on the holding member 1 is fastened to the portion 11 on the rear side of the valley portion 3. The fastening portion 12 is not limited to being fastened to the bottom end portion 3a of the valley portion 3, and may be fastened to a portion slightly distant from the bottom end portion 3a as viewed in the horizontal direction, as shown in Figures 15(D), (E), and (F). Also, the fastening portion 12 may be fastened to the position of a connection portion 79 described later or to a portion close to the connection portion 79.

In accordance with the present invention, by combining these wave form elements as required, it is possible to form a variety of wave forms 5 that are not restricted by the attachment position of the curtain hook relative to the rear surface 9 of the upper end portion 7 of the flat curtain 6, which is not possible with Patent Documents 1 and 2.

Figure 15 shows an example of the shape of the wave 5 of a flat curtain 6 that can be obtained by combining the required wave form elements.

In addition, in the present invention, the flat curtain holding member 1 is not attached to the curtain hook 13, so a flat curtain device 18 (Fig. 1) can be constructed with a desired shape of wave 5 that does not impede the running of the runner 16. When using the flat curtain device 18, the holding member 1 is arranged on the rear surface portion 9, so the holding member 1 is not visible. In particular, when the connection portion (white circle portion shown in the figure) 79 (Fig. 15) between the peak portion 2 and the valley portion 3 that constitute the wave 5 is suspended from the runner 16 via the curtain hook 13 to construct the flat curtain device 18, it is possible to construct a flat curtain device 18 with a good appearance in which the peak portion 2 and the valley portion 3 are formed on both the front and rear sides of the row of the curtain hooks 13.

In addition, when using the flat curtain device 18, the linear member 10 is not attached to the curtain hook 13, so even if the curtain hook 13 is removed from the flat curtain 6 when the curtain is washed, the shape of the wave 5 is not lost. In contrast, in the patent documents 1 and 2, the connector (Patent Document 1) and the fabric width adjustment band (Patent Document 2) are attached to the curtain hook as a means for forming the wave 5 in the flat curtain 6, so when the curtain hook is removed from the flat curtain 6 when the curtain is washed, the shape of the wave is lost at the same time. Therefore, in this case, the troublesome work of setting the pitch as required again and forming the wave is required after washing is required. With the present invention, such problems can be solved.

Another aspect of the flat curtain device 18 according to the present invention is to attach the upper end portion 7 of the flat curtain 6 to the rail body 69 of the rod-shaped curtain rail 67 using the flat curtain holding member 1 according to Figures 11, 12, and 13, for example. In this way, the flat curtain holding member 1 according to the present invention can also be used to easily attach the flat curtain 6 to the rod-shaped curtain rail 67. As a result, the flat curtain device 18 in which the flat curtain 6 is attached to the curtain rail 15 via the curtain hook 13 can be easily changed to a flat curtain device 18 in which the flat curtain 6 is attached to the rod-shaped curtain rail 67, and vice versa. This allows you to enjoy rearranging the flat curtain.

The present invention is by no means limited to the above examples, and it goes without saying that various design modifications are possible within the scope of the claims. One example is as follows.

(1) The flexible linear member 10 may be any flexible linear member having a tape, string, chain, or other shape that does not interfere with forming the wave 5 or constructing a flat curtain device using the rod-shaped curtain rail 67.

(2) The second engagement portion 20 is provided on the rear surface 9 of the upper end portion 7 of the flat curtain 6, but the rear surface 9 may be formed directly without using the fastening tape 26 described above.

(3) The first engaging portion 21 and the second engaging portion 20 can be configured by combining the shaft body 51 with the vertical insertion portion 43 or the horizontal insertion portion 45, or by combining first and second button members (the first and second engaging portions 20, 21) of various configurations, such as a button and a buttonhole that can engage with each other. Also, as shown in FIG. 16, various configurations can be made, such as a combination of a fishhook-shaped member (a type of protruding shaft portion that protrudes from one of the opposing ends of the linear member 10) as the first engaging portion 21 and various hook portions (the second engaging portion 20) that can be hooked onto it.

(4) The first engagement portion 21 and the second engagement portion 20 may be in a detachable engagement state, or may be in a non-detachable engagement state.

(5) The fastening portion 12 may be attached to the rear portion 11 of the valley portion 3 by sewing a required portion of the linear member 10 to the rear portion 9.

(6) Figure 4 (B) shows a case where the fastening portion 12 is configured by a shaft body 51 having two protruding shaft portions 50, 50 that protrude in a direction perpendicular to the extension direction of the linear member 10 from the upper and lower side edges 49a, 49b facing each other of the linear member 10, and the length of one protruding shaft portion 50a is formed longer than the length of the other protruding shaft portion 50b and is formed longer than the vertical length of the vertical insertion portion 43. In this case, for example, the long protruding shaft portion 50a is passed first from the inside of the vertical insertion portion 43 provided on the rear surface portion 9, and the part protruding at the tip side is grasped with fingers and pulled, which makes it easier to insert the entire shaft body 51 into the vertical insertion portion 43.

(7) Figure 17 shows another embodiment of the flat curtain retaining member 1 in a long configuration, in which the shaft body 51 is configured as a double shaft body 81 in which the two shaft bodies 51, 51 are connected at their sides via a vertical groove 80, instead of the single shaft body shown in the figure. The shaft body 51 as the double shaft body 81 can also be inserted or inserted into the vertical insertion portion 43. When the shaft body is configured as the double shaft body 81, the double shaft body 81 can be cut at the vertical groove 80 to divide it into two, thereby forming a flat curtain retaining member 1 in which the fastening portion 12 made of the shaft body 51 is provided at both ends of the fixed-length linear member 10a.

(8) The bottom end 3a (Figure 15 (E)) of the valley portion 3 or the side close to the bottom end 3a of the valley portion 3 may be slidably hung on the runner 16 of the curtain rail 15 via the curtain hook 13.

(9) The flat curtain device 18 of the present invention can also be used in combination with other curtains, such as roller blinds, to create a double curtain with front and back layers.

(10) The curtain hook 13 may be, for example, hooked only onto the upper hook end portion insertion portion 37 shown in FIG. 5.

(11) The left-right insertion portion 44 can also be configured as a sheet piece, for example a piece of woven fabric.

(12) Figure 18 shows a case where the upper and lower hook end portion insertion portions 37, 39, the upper and lower vertical insertion portions 43, 43, and the horizontal insertion portion 44 are provided integrally with the tape base material 30, and two sets of the upper and lower vertical insertion portions 43, 43 are arranged on the left and right between the upper and lower hook end portion insertion portions 37, 39. In addition, the horizontal insertion portions 44, 44 are provided so as to sandwich the two sets of vertical insertion portions 43, 43 from both sides (left and right sides).
Furthermore, the upper and lower opposing partition edges 41, 41 of the upper and lower insertion portion forming tapes 40, the upper and lower opposing partition edges 47, 47 of the upper and lower insertion portion forming tapes 48, 48, and the left-right insertion portion 44 are arranged in a line perpendicular to the extension direction, and with respect to the upper and lower insertion portion forming tapes 48, 48, the upper and lower partition edges 47, 47 located between adjacent partition edges 41, 41 in the extension direction are arranged on the perpendicular line.
With this configuration, when the base tape 30 is made of a woven fabric, the weft yarns forming the base tape 30 can be used to form the upper and lower partition edges 41, 41, the upper and lower partition edges 47, 47, and the left and right insertion portion 44. This allows for rationalization of the weaving of the base tape 30.

(13) The shaft body 51 may be configured in a columnar shape, such as a cylindrical or rectangular column shape.

(14) When the fastening portion 12 is configured as the loop-shaped engaging piece 63, the receiving portion for hanging the hanging member 64 can be configured as required, such as the vertical insertion portion 43 described above, or a loop, ring, or hook shape to which the hanging member 64 can be hung.

(15) If the flat curtain holding member 1 used to attach the flat curtain 6 to the rod-shaped curtain rail 67 has the shaft body 77, when the shaft body 77 is inserted into the vertical insertion portion, it may be configured as a dedicated portion for that purpose rather than using the upper and lower hook end portion insertion portions 37, 39.

(16) If an extendable tension bar is used as the rod-shaped curtain rail 67, a flat curtain device using the rod-shaped curtain rail 67 can be used to form a room partition.
