Description

Technical Field

[0001] The present invention relates to a holding member for a flat curtain, and also to a flat curtain device using the same.

Background Art

[0002] As an example of a flat curtain in which waves formed by alternately connecting mountain portions and valley portions are formed, those disclosed in Patent Document 1 and Patent Document 2 are provided.

[0003] The flat curtain disclosed in Patent Document 1, in a suspended state, in order not to form an unnatural wave visually, a plurality of hanging tools are attached at a predetermined attachment interval along the upper edge portion of the curtain fabric, and an adjacent hanging tool and a hanging tool are connected by a connecting tool. A connecting section and a non-connecting section where adjacent hanging tools are not connected are alternately provided. Another aspect of the flat curtain disclosed in Patent Document 2 adopts a configuration in which a fixing rod of a curtain hook is inserted into a bent portion for an insertion hole of a fabric width adjusting band so that the size of the waveform formed on the curtain fabric and the width of the curtain fabric itself can be freely set. However, the flat curtains according to Patent Documents 1 and 2 have the following problems. That is,

[0004] (1) In the flat curtain disclosed in Patent Document 1, since adjacent hanging tools are connected by a connecting tool, a non-connecting section where adjacent hanging tools are not connected is generated between the connecting sections where adjacent hanging tools are connected by the connecting tool, and in this non-connecting section, the curved state of the upper edge portion of the curtain fabric becomes a state of being stretched, and there is a case where the "visually natural wave" aimed at by Patent Document 1 cannot be formed.

[0005] (2) According to the flat curtain disclosed in Patent Document 1, since adjacent hanging tools are connected by a connecting tool, there is a risk that the connecting tool may inhibit the running performance of the runner. In this regard, in paragraph 0017 of the specification of Patent Document 1, on the premise that "the main body of the hanging tool rotates when pulled by the connecting tool", it is stated that "according to the flat curtain of the present invention, by providing the main body of the hanging tool so as to be relatively rotatable with respect to the hook body, even if the main body of the hanging tool rotates when pulled by the connecting tool, or even if the main body of the hanging tool rotates so as to conform to the upper edge of the curved curtain fabric, no rotational force acts on the runner, and the running performance of the runner is not inhibited."

[0006] (3) As means for determining the form of the wave, in the flat curtain disclosed in Patent Document 1, adjacent hanging tools are connected by a connecting tool, and in the flat curtain disclosed in Patent Document 2, the fixing rod of the curtain hook is inserted into the bent portion for the insertion hole of the fabric width adjusting band. Therefore, in Patent Document 1 and Patent Document 2, there is a problem that the form of the wave of the curtain is restricted by the attachment position of the curtain hook, and there is a restriction on the form of the wave that can be formed on the curtain.

[0007] (4) In the flat curtain disclosed in Patent Documents 1 and 2, in order to form a wave in the flat curtain, the connecting tool (Patent Document 1) or the fabric width adjusting band (Patent Document 2) was attached to the hanging hook. Therefore, when the hanging hook was removed from the flat curtain during washing of the curtain, at the same time, the form of the wave collapsed. Therefore, after washing, there was a problem that a troublesome operation of re-setting the pitch as required and reforming the wave was required.

Mode for Carrying Out the Invention

Examples

[0033] In FIGS. 1 to 2, a holding member for a flat curtain (hereinafter also referred to as a holding member) 1 according to the present invention is used to form a flat curtain 6 in which waves 5 in which ridges 2 and valleys 3 are alternately connected are formed. An anchoring portion 12 is provided at required intervals on a flexible linear member 10 disposed in the extending direction on the rear surface portion 9 of an upper end side portion 7 of the flat curtain 6 and anchored to a rear surface side portion (a part of the rear surface portion 9) 11 of the valley 3.

[0034] FIGS. 1 and 3 show a flat curtain device 18 configured by hanging the flat curtain 6 on a suspension ring 17 of a runner 16 that slides in the longitudinal direction of a curtain rail 15 via a curtain hook 13 attached to the rear surface portion 9.

[0035] 1-2 and 4, the linear member 10 in this embodiment 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 which 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.

[0036] The flat curtain 6 is constructed by abutting a fastening tape 26, for example, as shown in Fig. 5 or 6, on 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 manner constitutes the upper end portion 7 of the flat curtain 6, and contributes to improving the rigidity of the upper end portion 7 and further improving the shape stability of the wave 5.

[0037] 1, 3, 5-6, the fastening tape 26 has a pair of upper and lower hook end portion inserting portions 37, 39 for inserting upper and lower hook end portions 35, 36 of the curtain hook 13, which are provided vertically facing each other on upper and lower edge sides 32, 33 of a surface 31 of a tape base material 30 formed as a woven or knitted tape of equal width, and which are arranged side by side in the extension direction of the tape base material 30. The upper and lower hook end portion inserting portions 37, 39 have the same configuration.

[0038] 5 and 6, an example of a method for forming the upper and lower hook end portion insert portions 37, 39 is as follows: on the surface 31 of the tape base 30, a hook end portion insert portion forming tape 40 extending in the length direction of the tape base 30 is disposed, and the insert portion forming tape 40 is integrated with the tape base 30 at intervals of 10 to 20 mm in the length direction by weaving, knitting, welding, sewing, or the like, for example by weaving, to form upper and lower opposing partition edges 41, 41. In this way, the upper and lower hook end portion insert portions 37, 39 can be formed between the adjacent partition edges 41, 41, the tape base 30, and the insert portion forming tape 40.

[0039] The tape base material 30 is sewn to the rear body part 25 of the curtain main body 22 with its back surface 42 in contact with the rear body part 25, thereby forming the rear part 9 (FIGS. 1 and 3). Then, as shown in FIGS. 1 and 3, the upper and lower hook end portions 35, 36 of the curtain hook 13 hung slidably on the curtain rail 15 and hooked on the hanging ring 17 of the runner 16 are inserted into a required set of the upper and lower hook end portion insertion parts 37, 39, whereby the curtain hook 13 is attached to the rear part 9 of the flat curtain 6 at a required interval.

[0040] FIG. 5 shows a left-right direction insertion part 44 as the second engaging part 20 with both left and right ends open. The left-right direction insertion part 44 is arranged in parallel at required intervals in the extension direction of the tape base material 30 at the central part 38 in the length direction of the surface 31 of the tape base material 30. FIG. 5(B) shows an example of the configuration of the left-right direction insertion part 44, which is composed of a plurality of, for example, 2 to 10 floating threads 46 whose both end parts 45, 45 are fixed to the tape base material 30 and are floating on the surface 31 of the tape base material 30. Its length in the vertical direction is set as required according to the width of the linear member 10, for example, 10 to 20 mm, and is set to 18 mm in this embodiment.

[0041] FIG. 6 shows up-down direction insertion parts 43, 43 as the second engaging part 20 with both upper and lower ends open. The up-down direction insertion parts 43, 43 are arranged in parallel at required intervals in the extension direction of the tape base material 30 in a vertically opposed state at the upper and lower parts of the central part 38 extending in the length direction of the surface 31 of the tape base material 30. In this embodiment, they are arranged in parallel at required intervals in the extension direction F1 between the upper and lower hook end portion insertion parts 37, 39.

[0042] FIG. 6 shows an example of how the pair of vertical insertion parts 43, 43 are formed. At the upper and lower parts of the central part 38 on the surface 31 of the tape base material 30, insertion part forming tapes 48, 48 arranged to extend in the extension direction F1 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 parts 43 are formed between adjacent partition edges 47, 47, the tape base material 30, and the insertion part forming tapes 48.

[0043] In this embodiment, the linear member 10 (FIG. 4) is configured as the dimensioned linear member 10a which is, for example, a woven tape or a knitted tape with 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 parts 12 as the first engaging parts 21 provided at both end parts 19, 19 seen in the extension direction F1 are, as shown in FIG. 4, formed by shaft bodies 51 (the first engaging parts 21) made of synthetic resin having protruding shaft parts 50 protruding in a direction perpendicular to the extension direction of the dimensioned linear member 10a at the opposing upper and lower side edges 49a, 49b of the dimensioned linear member 10a. The shaft body 51 has, for example, an elliptical cross-section with a major axis of 3.3 mm and a minor axis of 2.5 mm, and a total length set to 25 mm. Each of the both end parts 19, 19 of the dimensioned linear member 10a is embedded in the shaft body 51 during its injection molding. In FIG. 4, the end part 19 is arranged in the minor axis direction of the shaft body 51.

[0044] When the second engaging part 20 is constituted by the lateral insertion part 44 (FIG. 5(A)), the shaft body 51 is inserted into the lateral insertion part 44 provided on the rear surface part 9, and as shown by the dashed-dotted line in FIG. 5(B), the protruding shaft parts 50, 50 are engaged in a contacting state with the outer edges (upper and lower edges) 54, 54 of the lateral insertion part 44 seen in the lateral direction, preventing the shaft body 51 from moving inward in the lateral direction F2. As a result, the fastening part (the first engaging part 21) 12 as the shaft body 51 is fastened to the second engaging part 20 as the lateral insertion part 44.

[0045] Further, when the second engaging portion 20 is constituted by the vertical insertion portions 43, 43, as shown in FIG. 6, the upper and lower protruding shaft portions (the first engaging portion) 50, 50 of the shaft body 51 are inserted or inserted into the vertical insertion portions 43, 43 (the second engaging portions 20, 20) provided on the rear surface portion 9, so that the upper and lower protruding shaft portions (a part of the fastening portions 12, 12) 50, 50 are fastened to the rear surface portion 9.

[0046] In part A shown in FIG. 6, with the linear member 10 arranged on the rear surface portion 9 so as to extend in the extending direction of the rear surface portion 9, the two protruding shaft portions 50, 50 of the shaft body 51 are inserted into the vertical insertion portions 43, 43, and a state in which the fastening portion 12 is fastened to the rear surface portion 9 is shown. Also, in part B shown in FIG. 6, with the linear member 10 arranged in the same manner, the protruding shaft portions 50, 50 of the shaft body 51 are inserted through the vertical insertion portions 43, 43, and a state in which the fastening portion 12 is fastened to the rear surface portion 9 is shown. In order to achieve such an insertion-through state, the vertical length of the vertical insertion portions 43, 43 is set short, or the lengths of the upper and lower protruding shaft portions 50, 50 are set long.

[0047] The insertion-through state and the insertion state are preferably in a close state in which the both-end protruding shaft portions 50, 50 do not easily come out of the vertical insertion portions 43, 43. For this purpose, the interval between the adjacent partition edges 47, 47 of the vertical insertion portions 43, 43 is formed small, and the both-end protruding shaft portions 50, 50 are inserted or inserted through the vertical insertion portions 43, 43 in a tight manner.

[0048] Figs. 7 to 8 show another aspect of the holding member 1 for the flat curtain. It is used to form the flat curtain 6 in which waves 5 are formed with the peaks 2 and valleys 3 connected alternately. A flexible linear member 10 is arranged in the extending direction on the rear surface portion 9 of the upper end side portion 7 of the flat curtain 6, and a fastening portion 12 is provided which is fastened to the rear surface side portion 11 (Fig. 1) of the valley 3. The linear member 10 may be in the form of a tape or a string. In Figs. 7 to 8, it is in the form of a string. The fastening portion 12 is constituted by a fastening member 53 which projects in the downward direction F3 perpendicular to the extending direction F1 of the linear member 10 and through which the vertical insertion portion 43 (Figs. 6 and 7(B)) is inserted downward. In the state of being inserted, the fastening member 53 is provided with a retaining engagement portion 56 which engages with the front edge portions (the adjacent partition edges 41, 41) 55, 55 of the vertical insertion portion 43 as seen in the insertion direction and prevents the fastening member 53 from moving in the removal direction (the direction opposite to the insertion direction).

[0049] In Fig. 9, the fastening portion 12 projects in the upward direction F4 perpendicular to the extending direction F1 of the linear member 10. Such upward projection 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 the upward direction perpendicular to the extending direction F1. Thereby, the same operational effects as those in the case of inserting downward are obtained, and the movement of the fastening member 53 in the removal direction (the direction opposite to the insertion direction) is prevented.

[0050] The configuration of the fastening member 53 as the first engaging portion 21 provided at both ends of the linear member 10 having a string-like shape will be described more specifically with reference to FIGS. 7 to 8. A triangular plate-like portion 59 protrudes from the tip of a rectangular plate-like portion 57 that can be inserted into the vertical insertion portion 43, presenting an arrow plate-like shape. It is integrated with the end portion 19 of the linear member 10 by injection molding. Both side portions 60, 60 on the base end side of the triangular plate-like portion 59 constitute the anti-loosening engaging portions 56, 56, and protrude on both sides of the tip of the rectangular plate-like portion 57. Further, a split groove 58 that opens at the center of the tip of the triangular plate-like portion 59 is provided across the triangular plate-like portion 59 and the rectangular plate-like portion 57.

[0051] 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 if necessary, and the triangular plate-like portion 57 expands the vertical insertion portion 43 and protrudes from its tip. The engaging step portions 61, 61 on both sides provided on both side portions 60, 60 of the triangular plate-like portion 59 engage with both end edge portions (the adjacent partition edges) 41, 41 on the front side of the vertical insertion portion 43. As a result, the movement of the fastening member 53 in the removal direction (the direction opposite to the insertion direction) is blocked, and the fastening member 53 is fastened to the portion 11 on the rear surface side of the trough portion 3.

[0052] Figs. 10(A) and (B) show another embodiment of the flat curtain holding member 1, which is a flat curtain holding member used to form the flat curtain 6 in which waves 5 with alternating ridges 2 and valleys 3 are formed. The holding member 1 includes a linear member 10 as a flexible dimensioned linear member 10a disposed in the extending direction at the rear surface portion 9 of the upper end side portion 7 of the flat curtain 6, and a fixing portion 12 formed by a loop-shaped engaging piece 63 (the first engaging portion 21) fixed to the rear surface side portion 11 (Fig. 1) of the valley portion 3. Fig. 10(B) shows a state in which the fixing portion 12 is fixed to, for example, the vertical insertion portion 43 by using a hanging member 64, such as an S-shaped ring 64a, which is hung on the loop-shaped engaging piece 63. Fig. 10(C) shows another embodiment of the loop-shaped engaging piece 63, which is composed of floating pieces 66 provided at required intervals in the length direction of a tape-like member 65 on the surface of the tape-like member 65, with both ends connected to the tape-like member so that the intermediate portion floats from the tape-like member 65. In this case as well, similar to the above, for example, by using the S-shaped ring, the fixing portion 12 as the loop-shaped engaging piece 63 can be fixed to the vertical insertion portion 43.

[0053] In Figs. 4(A), 7(A), 8, and 10(A), the flat curtain holding member 1 shown in a state of being extended by a dashed-dotted line has a long linear member 10. A number of the fixing portions 12 fixed to the rear surface side portion 11 of the valley portion 3 are provided at required intervals on the linear member 10.

[0054] The fixing portion 12 provided on the linear member 10 is fixed to the second engaging portion 20 set at the rear surface side portion 11 of a specific valley portion 3 selected according to the form of the wave 5 desired by the user during its use, and is not necessarily fixed to the rear surface side portions 11 of all valley portions.

[0055] When using such a long flat curtain holding member 1, compared with the case where the linear member 10 has the above dimensions, there is an effect that the number of operations for fixing the upper end side portion 7 of the flat curtain 6 to the rear surface portion 9 can be reduced.

[0056] Figs. 11 to 13 show other aspects of the flat curtain holding member 1 according to the present invention, and are used for attaching the upper end side portion 7 of the flat curtain 6 to the rail body 69 of the rod-shaped curtain rail 67. The curtain holding member 1 is provided with fixing portions 12 fixed to the rear surface portion 9 at both ends 70, 71 of a flexible linear member 10 arranged in the vertical direction at the rear surface portion 9 of the upper end side portion 7 of the flat curtain 6. With the fixing portions 12, 12 fixed to the rear surface portion 9, the rail body 69 can be held in an inserted state in an insertion holding portion 72 (Figs. 11 and 12) formed between the rear surface portion 9 and the linear member 10, or in a loop-shaped portion 73 (Fig. 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.

[0057] In this embodiment, the linear member 10 is set to have 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.

[0058] Figs. 11 to 13 show an example of the fixing portion 12. The fixing portion 12 is configured in the same manner as in the case of forming the wave 5, for example, and at the upper and lower ends 70, 71 of the linear member 10, it is configured by a shaft body 77 having the same configuration as described above, with protruding shaft portions 76, 76 protruding in a direction perpendicular to the extending direction of the linear member 10 at the opposing left and right side edges 75, 75. The holding member 1 according to this embodiment uses the linear member 10 of the holding member 1 for forming the flat curtain in the vertical direction instead of the left-right direction described above.

[0059] In the fixed state of the fixing portion 12 shown in FIG. 11, the upper and lower shaft bodies 77, 77 are inserted from the inside thereof toward the outside into, for example, the upper and lower hook end portion insertion portions 37, 39, and the protruding shaft portions 76, 76 are engaged with the front edge portions (the adjacent partition edges 41, 41) 55, 55 of the hook end portion insertion portions 37, 39 as viewed in the insertion direction. In the fixed state of the fixing portion 12 shown in FIG. 12, the upper and lower shaft bodies 77, 77 (functioning in the same manner as the shaft bodies 51, 51) are inserted from the outside thereof toward the inside into the upper and lower hook end portion insertion portions 37, 39, and the two protruding shaft portions 76, 76 are engaged with the front edge portions (the adjacent partition edges 41, 41) 55, 55 of the hook end portion insertion portions 37, 39 as viewed in the insertion direction.

[0060] Also, in the fixed state of the fixing portion 12 shown in FIG. 13, both of the protruding shaft portions 76, 76 of the upper and lower shaft bodies 77, 77 are inserted from the inside thereof toward the outside into, for example, the upper hook end portion insertion portion 37, and the two protruding shaft portions 76, 76 are engaged with the front edge portions (the adjacent partition edges 41, 41) 55, 55 of the hook end portion insertion portion 37 as viewed in the insertion direction.

[0061] FIGS. 1 to 2 show an example of a flat curtain device 18 using a flat curtain 6 in which waves 5 in which the mountain portions 2 and the valley portions 3 are alternately connected are formed, and the waves 5 are configured using a required number of the illustrated holding members 1. These holding members 1 are all used to form a flat curtain 6 in which waves 5 in which the mountain portions 2 and the valley portions 3 are alternately connected are formed, and the adjacent fixing portions 12, 12 of the holding members 1 are fixed to the respective rear surface side portions (in FIG. 1, the vicinity of the bottom end portion 3a of the valley portion 3) 11, 11 of the adjacent valley portions 3, 3. As a result, the base end widths (pitches) of the mountain portions 2, 2 are regulated by the length between the two fixing portions 12, 12 of the linear member 10.

[0062] Here, the main wave form elements that determine the form of the wave 5 will be described based on FIGS. 2 and 14 to 15. (1) All or a part of the rear surface side portions 11, 11 of the adjacent valleys 3, 3 are connected by the holding member 1 (see FIGS. 2 and 15). (2) The wave form is determined by the width (pitch P) and the mountain height H of the mountain portion 2 of the wave 5 (see FIGS. 14(A) and (B)). (3) By setting the position of the second engaging portion 20 in the rear surface portion 9 as required, the height H of the mountain portion 2 can be changed while keeping the pitch P the same (see FIG. 14(A)). For example, while keeping the pitch the same, the height of the mountain portion 2 can be changed to H1 and H2. (4) By setting the position of the second engaging portion 20 in the rear surface portion 9 as required, the pitch P can be changed while keeping the height H of the mountain portion 2 the same (see FIG. 14(B)). For example, while keeping the height of the mountain portion 2 the same, the pitch P can be changed to pitch P1 and pitch P2. (5) The fastening portion 12 provided on the holding member 1 is fastened to the rear surface side portion 11 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. For example, as shown in FIGS. 15(D), (E), and (F), it can be fastened to a portion slightly separated from the bottom end portion 3a when viewed in the horizontal direction. It may also be fastened to the position of the connecting portion 79 described later or a portion close to the connecting portion 79.

[0063] According to the present invention, by a required combination of these wave form elements, it is possible to form a wave 5 of various forms that is not restricted by the attachment position of the curtain hook to the rear surface portion 9 of the upper end side portion 7 of the flat curtain 6, which cannot be obtained by Patent Documents 1 and 2.

[0064] FIG. 15 illustrates the form of the wave 5 of the flat curtain 6 obtained by a required combination of the wave form elements.

[0065] Moreover, in the present invention, since the flat curtain holding member 1 is not attached to the curtain hook 13, a flat curtain device 18 (Fig. 1) having a desired form of the wave 5 in which the running performance of the runner 16 is not inhibited can be configured. When using the flat curtain device 18, since the holding member 1 is arranged on the rear surface portion 9, the holding member 1 is not visible. In particular, when the flat curtain device 18 is configured by suspending the connecting portion (white circled portion shown in the figure) 79 (Fig. 15) between the peak portion 2 and the valley portion 3 constituting the wave 5 via the curtain hook 13 to the runner 16, 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 can be configured.

[0066] Moreover, when using the flat curtain device 18, since the linear member 10 is not fixed to the curtain hook 13, the form of the wave 5 does not collapse even when the curtain hook 13 is removed from the flat curtain 6 during curtain washing. On the other hand, in Patent Documents 1 and 2, as means for forming the wave 5 in the flat curtain 6, the coupler (Patent Document 1) or the fabric width adjusting band (Patent Document 2) was attached to the curtain hook. Therefore, when the curtain hook was removed from the flat curtain 6 during curtain washing, the form of the wave collapsed simultaneously. Therefore, in this case, after washing, a troublesome operation of re-setting the pitch as required and forming the wave had to be performed. According to the present invention, such problems can be solved.

[0067] 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 by using, for example, the holding member 1 for the flat curtain according to FIGS. 11, 12, and 13. Thus, the holding member 1 for the flat curtain according to the present invention can also be used to easily attach the flat curtain 6 to the rod-shaped curtain rail 67. Therefore, 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 one to enjoy changing the pattern of the flat curtain.

Example

[0068] The present invention is by no means limited to what is shown in the above embodiment, and it goes without saying that various design changes are possible within the scope of the claims. An example is as follows.

[0069] (1) The flexible linear member 10 may be in the form of a tape, a string, a chain, or any other flexible linear member that does not interfere with forming the wave 5 or constituting a flat curtain device using the rod-shaped curtain rail 67.

[0070] (2) The second engaging portion 20 is provided on the rear surface portion 9 of the upper end portion 7 of the flat curtain 6, and the rear surface portion 9 may be directly formed without using the fixing tape 26 described above.

[0071] (3) The first engaging portion 21 and the second engaging portion 20 can be constituted by the combination of the shaft body 51 and the vertical insertion portion 43 or the horizontal insertion portion 45, and can also be constituted by the combination of first and second button members (the first and second engaging portions 20, 21) of various configurations such as buttons and button holes that can engage with each other. Also, as shown in Fig. 16, various configurations can be made, such as a combination of a hook-shaped member as the first engaging portion 21 (a kind of protruding shaft portion that protrudes from either one of the opposing portions of the linear member 10) and various hooking portions (the second engaging portion 20) that are hooked thereon.

[0072] (4) The first engaging portion 21 and the second engaging portion 20 can be in a detachable engaging state, and can also be in a non-detachable engaging state.

[0073] (5) The fixing of the fixing portion 12 to the portion 11 on the rear surface side of the groove portion 3 may be performed by sewing a required portion of the linear member 10 to the rear surface portion 9.

[0074] (6) Fig. 4(B) shows a case where the fixing portion 12 is constituted by a shaft body 51 having both protruding shaft portions 50, 50 that protrude in a direction perpendicular to the extending direction of the linear member 10 at the upper and lower side edges 49a, 49b of the linear member 10 that face each other. In this case, for example, the longer protruding shaft portion 50a is first passed through from the inside of the vertical insertion portion 43 provided in the rear surface portion 9 in order, and the portion protruding from the front side thereof is gripped with a finger and pulled, so that the operation of inserting the entire shaft body 51 into the vertical insertion portion 43 can be facilitated.

[0075] (7) Fig. 17 shows another embodiment when the flat curtain holding member 1 is configured to be long. Instead of the single shaft body shown in the figure, the shaft body 51 is configured as a double shaft body 81 in which two of the shaft bodies 51, 51 are connected to each other at their sides via a vertical groove 80. The shaft body 51 as the double shaft body 81 can also be inserted or passed through the vertical insertion portion 43 in the vertical direction. When the shaft body is configured as the double shaft body 81, by cutting the double shaft body 81 at the vertical groove 80 and splitting it into two, a flat curtain holding member 1 can be configured in which fixing portions 12 made of the shaft body 51 are provided at both ends of the dimensioned linear member 10a.

[0076] (8) The bottom end portion 3a of the valley portion 3 (Fig. 15(E)) or the side closer to the bottom end portion 3a of the valley portion 3 may also be slidably suspended from the runner 16 of the curtain rail 15 via the curtain hook 13.

[0077] (9) The flat curtain device 18 according to the present invention can also be used to form a front and rear double curtain in combination with other curtains such as a roller screen.

[0078] (10) The curtain hook 13 may be hung only on, for example, the upper hook end portion insertion portion 37 shown in Fig. 5.

[0079] (11) The lateral insertion portion 44 can also be configured as a sheet piece, for example, a woven fabric piece.

[0080] (12) Fig. 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 lateral insertion portion 44 are integrally provided on the tape base material 30. Between the upper and lower hook end portion insertion portions 37, 39, two sets of the pair of the upper and lower vertical insertion portions 43, 43 are arranged on the left and right. Also, the lateral insertion portions 44, 44 are provided so as to sandwich the two sets of the vertical insertion portions 43, 43 from both sides (left and right sides). Moreover, the vertically opposing partition edges 41, 41 of the upper and lower insertion part forming tapes 40, the vertically opposing partition edges 47, 47 of the upper and lower insertion part forming tapes 48, 48, and the left-right direction insertion part 44 are arranged linearly perpendicular to the extension direction, and with respect to the upper and lower insertion part forming tapes 48, 48, the upper and lower partition edges 47, 47 existing between the adjacent partition edges 41, 41 in the extension direction are arranged on the perpendicular line. By configuring in this way, when the base material tape 30 is made of a woven fabric, the weft threads forming the base material tape 30 can be used to form the upper and lower partition edges 41, 41, to form the upper and lower partition edges 47, 47, and to form the left-right direction insertion part 44. Thereby, the rationalization of the weaving of the base material tape 30 can be achieved.

[0081] (13) The shaft body 51 may be configured in a columnar shape such as a cylindrical shape or a prismatic shape.

[0082] (14) In the case where the fixing part 12 is configured as the loop-shaped engaging piece 63, the part to be hung for hanging the hanging member 64, in addition to the above-described vertical direction insertion part 43, can be configured as required, such as a loop-shaped, ring-shaped, hook-shaped one that can hang the hanging member 64.

[0083] (15) When the flat curtain holding member 1 used for attaching the flat curtain 6 to the bar-shaped curtain rail 67 has the shaft body 77, when inserting the shaft body 77 into the vertical direction insertion part, instead of using the above-described upper and lower hook end part insertion parts 37, 39, it may be configured as a dedicated one.

[0084] (16) If a telescopic tension bar is used as the bar-shaped curtain rail 67, the flat curtain device using the bar-shaped curtain rail 67 can also be used to form a room partition.
