Description

  The present invention relates to a curtain, and more particularly to a drape curtain in which a longitudinal drape is beautifully formed when opened and closed, and the light shielding property is improved when closed.

  Conventional drape curtains can be broadly classified into the following two types according to a method of forming a “claw” called drape. One type is to form a “tack part” by pinching the top of the curtain and fixing it by sewing etc., and to form a “hook” under this “tack part”. The drape is formed by sandwiching the curtain fabric between two patterns and heating and cooling, that is, by applying pleats.

  In the drape curtain of the first type above, the drape appears beautifully just under the tack part, but gradually collapses from the center and disappears completely at the bottom, making it beautiful overall Not a thing. On the other hand, in the drape curtain of the second type, in the cross-sectional shape of each drape, “U-shaped part” and “inverted U-shaped part” are alternately continued, which can be called “drape”. This is common.

  In such a drape curtain in which the “U-shaped portion” and the “inverted U-shaped portion” are alternately continued, since all portions are curved, the drape does not appear clearly. Moreover, in order to connect the drape curtain to the curtain rail, a latch must be attached, but this latch must be attached to the upper part of the curtain which is a “U-shaped part” or “inverted U-shaped part”. Don't be. Then, the force is partially applied to the “U-shaped part” or “inverted U-shaped part” at the upper part of the curtain depending on the weight of the curtain itself, which disturbs the draped drape.

  On the other hand, in recent curtains, including this type of draped curtain, it is easy to see by reducing the reflection of the computer screen in the daytime, or to prevent the light from the room from leaking outside at night. In addition, there is a demand for an excellent “light-shielding property” that does not allow light from inside and outside to pass.

  In order to enhance the “light-shielding property” of the curtain, it is naturally considered that the “curtain fabric” itself is thick or made of a material with excellent light-shielding properties. If it is only excellent, it will not be possible to secure sufficient light-shielding properties when the curtain is closed. This is because if there is a gap between the curtains or between the curtain and the wall constituting the window, light leaks from here. As such a technique in consideration of the light shielding property of the curtain, for example, there are those shown in Patent Documents 1 to 3.

  The invention described in Patent Document 1 relates to a “curtain” made for the purpose of “providing a curtain with high light-shielding properties”. As shown in FIG. The base end portions 31 that are folded back and sewed together are sewn at the base end portion sewing portion 32 to form a loop-shaped overlapping portion 33. This lining 11 is superimposed on the outer surface 12, and the lower edge from the base end of the overlapping portion 33 The lining 11 is sewed on the outer surface 12 along the joining sewing portion 41 on the side 22. The overlapping portion 33 is arranged on the joining sewing portion 41, and the fixing sewing portion 51 at the tip of the overlapping portion 33 is attached to the lining 11. A bar-like member 71 is provided between the lining 12 and the overlapping portion 33, and sewing is performed with the retaining portion 72. These steps are repeated up to the lower edge 22 side.

  However, in the “curtain” of this patent document 1, by devising the curtain fabric itself, “a pinhole penetrating the outer material and the lining is formed along the sewing part. This prevents the light from being transmitted through this pinhole, no matter how thick the lining is used, and constitutes curtains or curtains and windows. It does not solve the problem of light leaking from the gap between the wall and the wall.

  The invention described in Patent Document 2 was made for the purpose of “providing a pleated curtain capable of preventing leakage of external light from the overlapping portion of the curtain fabric and improving workability during assembly”. As shown in FIG. 10, “pleat curtains” are supported by suspending curtain fabrics 3 a and 3 b from a head box that can be bent at an arbitrary angle, and bottom rails at the lower ends of the curtain fabrics 3 a and 3 b. In the pleated curtain in which the curtain fabrics 3a and 3b can be moved up and down by operating the lifting cord inserted into the curtain fabrics 3a and 3b to raise and lower the bottom rail, each of the overlapping portions of the curtain fabrics 3a and 3b The elevating cords 4b and 4c are inserted into at least one of the curtain fabrics, and the elevating cords 4b and 4c have a curtain. Land 3a, is abutted against the end of 3b, the curtain fabric 3a, and regulate the front-rear direction of the turnover 3b "is intended.

  However, in the pleated curtain of Patent Document 2, the curtain fabrics 3a and 3b can be moved up and down by operating the lifting cord inserted into the curtain fabrics 3a and 3b to raise and lower the bottom rail. In addition to being unable to open and close in the direction, it has a complicated structure in which “bottom rails must be attached to the lower ends of the curtain fabrics 3a and 3b”.

  Further, the invention described in Patent Document 3 states that “a light shielding method using a curtain body with a light shielding lining that can easily and easily perform the work of attaching and detaching the back curtain body attached to the front curtain body and the work for changing the light shielding property, and the light shielding lining thereof. The present invention relates to “a light shielding method by a curtain body with a light-shielding lining and a curtain body with light shielding lining”, which is made for the purpose of “providing a curtain with a light-shielding lining”. As shown in FIGS. Then, after superimposing on the back surface side of the surface curtain A of approximately 1.5 times specification or approximately 2 times specification, the suspension portion 5c of the suspension body 5 constituting the suspension tool 4 is inserted into the insertion portion of the surface curtain A. Suspension tool 4 inserted at a predetermined interval along the upper edge of surface curtain A and lining curtain B, and inserted into hole Ba of lining curtain B communicating with Aa. , Curtain Suspended by the runner 3 inserted in the rod 2. The light-shielding lining curtain B is also attached to the surface curtain A of about 1.5 times or about 2 times the specification, and the light shielding property of the surface curtain A is attached. Change ".

However, in the curtain of Patent Document 3, as in the curtain described in Patent Document 1, it is intended to prevent “light from transmitting through the curtain fabric”, and the curtains or the curtains can be prevented. It does not solve the problem that light leaks from a gap formed between the window and the wall constituting the window.

As described above, there are various technologies that take into consideration the “light shielding” in the “curtain”.
(1) Make good use of beautiful drapes with a simple structure (2) Clearance between the curtains or between the curtain and the walls that make up the window when the curtain that can be opened laterally is closed (3) It does not mean that it can be formed by a simple manufacturing method, and it is considered that the curtain does not have a sufficient light shielding property.

  Therefore, the present inventors have completed the present invention as a result of various studies on how to make a curtain that can achieve at least the above points (1) to (3). It is.

That is, the object of the present invention is to
(1) Make the most of beautiful drapes with a simple structure (2) Clearance between the curtains or between the curtain and the wall that forms the window when the curtain that can be opened horizontally is closed (3) To provide a drape curtain that can be formed by a simple manufacturing method.

In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the best mode described below.
“A large number of drapes 11 suspended in the curtain rail 20 are in the vertical direction, and each drape 11 is separated by a valley fold pleating line 12 formed in the vertical direction of the curtain fabric, and between each valley fold pleating line 12. The curtain fabric positioned at the position of the fold pleats 12 is hung with a curved pleat that is curved on the opposite side of the valley fold pleating line 12 so that the cross section is in a cycloid curved state. In the drape curtain 10 in which it is not necessary to form a tack part in the part,
The drape curtain 10 is characterized in that at least at the vertical end portion of the drape 11 located at the tip, the overlap portion 10a on the other drape curtain 10 side or the overlap portion 10a overlapping the wall constituting the window 30 is formed.
It is.

  That is, in the drape curtain 10 according to the first aspect, first, the drape 11 is not formed with a tack portion, and each drape 11 is formed by a general pleating process. The cross-sectional shape in which a large number of slabs are made continuous is a cycloid curve state. A cycloid curve refers to a locus drawn by a point on a circle when the circle rolls in contact with a circle. In the drape curtain 10 according to the present invention, as shown in FIG. A cross-sectional shape in which a large number of drapes 11 are continuous is approximated to this cycloid curve.

  In order to form such a drape 11, for example, a valley fold corresponding to the valley fold pleating line 12 is formed on two sheets of paper, and between these valley folds, on the opposite side to the valley fold. A curved portion that is curved is formed, and a curtain fabric is sandwiched between these patterns, and a normal pleating process is performed. Note that the “valley fold” is a folding method that becomes a recessed portion when the drape curtain 10 is viewed from the room side, as shown in FIG.

  When the drape curtain 10 thus developed is deployed, as shown on the left side of FIG. 1, each valley fold pleating line 12 recessed on the window 30 side has a so-called “shadow”, so each valley fold pleating line 12 and the drape 11 delimited thereby will look very clear and beautiful. Further, when the drape curtain 10 is closed as shown on the right side of FIG. 1, each valley fold pleating line 12 is recessed toward the window 30, and the curtain fabric positioned between each valley fold pleating line 12. Since the curved pleats that are curved on the opposite side (room side) to each of the valley fold pleating lines 12 are hung, all the drapes 11 are curved so that the center protrudes toward the room side. It reflects the illumination and maintains its appearance without disappearing.

  Of course, the drape curtain 10 must be hung on the curtain rail 20 provided on the inner upper portion of the window 30, but it is not necessary to form a tack portion for that purpose. As shown in FIGS. 2 and 3, the upper part (the valley fold pleating line 12 on the outer side surface (the surface on the side of the window 30, which cannot be seen from the room side) of each valley fold pleating line 12. 2 cm from the upper end of the head, or 2 to 3 cm from here). That is, when the drape curtain 10 is suspended from the curtain rail 20, its own weight is applied to each valley fold pleating line 12, and each drape 11 separated by these valley fold pleating lines 12 is applied. The direct force should not be applied. As a result, when the drape curtain 10 is suspended from the curtain rail 20 using the latch 13, the drape 11 does not lose its shape because no force is applied to the drape 11 to disturb its shape. .

  By the way, the width of the window 30 has been various in recent years, and the width of the curtain cloth is fixed and fixed even if several kinds are prepared. Such curtain fabric is in a state where it must be used efficiently while avoiding the wasteful work of cutting as much as possible. In this regard, in the drape curtain 10 of the present invention, each drape 11 is separated by a valley fold pleating line 12 formed in the longitudinal direction of the curtain fabric, and the curtain located between the valley fold pleating lines 12. Since the fabric is made to hang a curved pleat that curves to the opposite side of the valley fold pleating line 12, each drape 11 sufficiently absorbs the dimensional difference, and the curtain fabric does not have to be cut. It has become.

  And what is important in the drape curtain 10 according to claim 1 is that, as shown in FIG. 1 to FIG. 5, at least the vertical end portion of the drape 11 located at the front end is overlapped portion 10a on the other drape curtain 10 side. Or it is having formed the superimposition part 10a which overlaps with the wall which comprises the window 30. FIG.

  The overlapping portion 10a is formed continuously with the drape 11 located at the side end, and the overlapping portion 10a is also pleated. When the drape curtain 10 is opened as shown on the left side of FIG. 1, the pleats hung on the overlapping portion 10a are hung so that the overlapping portion 10a is parallel to the curtain rail 20 as shown in FIG. Further, not the curved pleats but flat pleats are applied to the entire overlapping portion 10a. A parallel fold pleating line 12 a that makes the overlapping portion 10 a parallel to the curtain rail 20 is actively hung on the inner edge of the overlapping portion 10 a at the boundary with the adjacent drape 11. Thus, the beauty of the drape 11 adjacent to the overlapping portion 10a is not impaired.

  Of course, the length of each overlapping portion 10a in the vertical direction is the same as that of each drape 11, and the width in the horizontal direction is 3 to 5 cm in the best mode to be described later. Further, for example, as shown in FIG. 1, when the overlapping portion 10 a covers one window 30 with two drape curtains 10 facing each other, the leading end side of each drape curtain 10 (ends facing each other). However, it may be formed on the wall side constituting the window 30 and may be implemented. In other words, when the drape curtain 10 has a sufficient width, the drape 11 on the wall side covers the gap between the wall and the overlap portion 10a on the wall side is not necessary. In the portions facing each other, an overlapping portion for preventing light from passing through must be formed.

  Of course, the latch 13 must be attached to the vicinity of the upper end portion of the valley fold pleating line 12 positioned in the immediate vicinity of the overlapping portion 10a. Otherwise, the overlapping portion 10a and the upper end of the drape 11 adjacent thereto hang down. In addition, it is advantageous for each latch 13 to be attached about 5 mm below the upper end of the drape curtain 10 in order to attach the drape curtain 10 to the curtain rail 20 without a gap.

  As described above, each drape is formed by forming at least the overlapping portion 10a on the other drape curtain 10 side or the overlapping portion 10a overlapping the wall constituting the window 30 at the vertical end portion of the drape 11 located at the tip. When the curtain 10 is closed, as shown in FIG. 3, the overlapping portions 10a overlap each other, and the wall side of the window 30 is also prevented from passing light by the overlapping portion 10a. Provides sufficient light shielding.

  In addition, as each latch 13 located at the tip of each drape curtain 10, a built-in magnet is used, and many of them are attracted to each other when each drape curtain 10 is closed. When such a latch 13 is used, if it is a general curtain, the tips of the curtains seem to come into contact with each other. However, since the curtain fabric itself is flexible, Will create a gap. In this respect, in the drape curtain 10 according to the present invention, since the overlapping portion 10a exists at the end thereof, these overlapping portions 10a overlap each other when the latches 13 are attracted as shown in FIG. The gap through which light passes is completely filled, that is, blocked.

  Therefore, the drape curtain 10 according to claim 1 does not need to form a tuck portion in which each drape 11 always looks clear and beautiful, causing the disturbance of the drape 11, and is closed when opened. Sometimes, not only can the beauty of the drape 11 be shown, but also the gaps when closed can be completely prevented by the respective overlapping portions 10a and have a very high light-shielding property. It is.

In order to solve the above-mentioned problem, the means taken by the invention according to claim 2 is about the drape curtain 10 according to claim 1 above.
“The overlapping portion 10a is provided with the fixing portion 16 attached to the overlapping portion 10a on the other drape curtain 10 side or the fixing portion 16 provided on the wall constituting the window 30”.
It is.

  That is, in the drape curtain 10 according to the second aspect, as shown in FIG. 4, the overlapping portion 10 a is provided with a fixing portion 16 such as a hook-and-loop fastener, a magnet, or a hook. Each superposed portion 10a is not easily separated. Of course, since the overlapping portion 10a is formed at the end portion of the drape curtain 10 itself, this overlapping portion 10a provides a mounting place for the fixing portion 16 without disturbing the shape of each drape 11. .

  In the drape curtain 10 having such a fixing portion 16, the superimposed portions 10 a are not separated from each other, so that even if the window 30 is opened to allow air to enter and exit, sufficient light shielding is achieved. It will be done. Similarly, even when the window 30 is closed and the wind from the air conditioner in the room is increased, the overlapping portions 10a overlapped by the fixing portion 16 are not separated from each other. Can be done.

  Therefore, the drape curtain 10 according to the second aspect exhibits the same effect as that of the first aspect, and has a sufficient light shielding property when the window 30 is opened and the air conditioner is operated strongly. It has become.

In order to solve the above-mentioned problem, the means taken by the invention according to claim 3 is about the drape curtain 10 according to claim 1 or 2,
“The overlapping portion 10a is made harder than the drape 11 by having the core material 10b.”
It is.

  That is, in the drape curtain 10 according to the third aspect, as shown in FIG. 5, the overlapping portion 10a has a core material 10b. The core material 10b may be formed by winding the dough constituting the overlapping portion 10a three times as shown in FIG. 5 and attaching the dough. The overlapping portion 10a is formed in a bag shape. The core material 10b made of another material may be inserted into the bag before being installed in the window 30 of the drape curtain 10. Further, the core member 10b may be an iron plate with a magnetic force.

  As described above, when the overlapping portion 10a of the drape curtain 10 has the core material 10b, the overlapping portion 10a has rigidity so as to ensure the overlapping action, and the overlapping portion 10a. The original light shielding property can be made sufficient.

  Therefore, the drape curtain 10 according to claim 3 exhibits the same function as that of claim 1 or claim 2, and the light shielding property of the overlapping portion 10a is further enhanced by the rigidity of the core member 10b. It is.

As described above, in the present invention,
“A large number of drapes 11 suspended in the curtain rail 20 are in the vertical direction, and each drape 11 is separated by a valley fold pleating line 12 formed in the vertical direction of the curtain fabric, and between each valley fold pleating line 12. The curtain fabric positioned in the above is placed on the opposite side of the valley pleat processing line 12 with a curved pleat so that the cross section is in a cycloid curved state, and all the valley fold pleats 12 and all the curved pleats are In the drape curtain 10 in which it is not necessary to form a tack portion in the portion,
At least at the vertical end portion of the drape 11 positioned at the tip, the overlapping portion 10a on the other drape curtain 10 side or the overlapping portion 10a overlapping the wall constituting the window 30 is formed.
The main features of the present invention are as follows.
(1) Make the best use of the beautiful drape 11 with a simple structure. (2) When the curtain 10 that can be opened laterally with respect to the window 30 is closed, between the curtains 10 or between the curtain 10 and the wall constituting the window 30. (3) It is possible to provide the drape curtain 10 that can be formed by a simple manufacturing method.

  Next, the invention according to each claim configured as described above will be described with respect to the drape curtain 10 which is the best mode shown in the drawings. The drape curtain 10 of this best mode is shown in FIGS. Example 1, Example 2 shown in FIG. 4, Example 3 shown in FIG. 5, Example 4 shown in FIG. 6, and Example 5 shown in FIGS. Therefore, the following description will be made in the order of each embodiment.

  FIG. 1 shows a state in which the drape curtain 10 according to the present invention is opened on the left side of the window 30 and closed on the right side of the window 30. Of course, these drape curtains 10 are suspended from the curtain rail 20, and a large number of drapes 11 to 11 are positioned in the vertical direction.

  In this drape curtain 10, as shown in FIGS. 1 and 2, each drape 11 is separated by a valley fold pleated line 12 formed in the longitudinal direction of the curtain fabric, and each valley pleated line 12. The curtain fabric positioned in between is hung with a curved pleat that is curved on the opposite side of the valley fold pleating line 12 so that the cross section is in a cycloid curve state.

  Moreover, in this drape curtain 10, the overlapping part 10a is integrally formed in the edge part of each drape 11 located in both ends, and a parallel folding pleat process is carried out between this overlapping part 10a and the drape 11 adjacent. A line 12a is formed. The parallel fold pleating line 12a is used to make the overlapping portion 10a substantially parallel to the curtain rail 20 when the drape curtain 10 is unfolded. The state is loosened. Of course, each overlapping portion 10a is applied with “planar pleats”, that is, pleats such that the overlapping portion 10a becomes flat.

  The drape curtain 10 was formed as follows. First, in order to manufacture a drape curtain 10 that covers a single glass window having a width of 90 cm, a curtain fabric made of polyester fiber and having a width of 150 cm is prepared and sandwiched between two patterns. And inserted into the steam kettle. Of course, each paper pattern has a dent corresponding to the valley fold pleating line 12, a curve corresponding to the drape 11 between the dents, and a dent corresponding to the parallel fold pleating line 12a adjacent to the drape 11 at both ends. In addition, a large number of curtain fabrics sandwiched between two patterns are inserted into one steam pot. In the state as described above, steam was heated at a temperature of about 105 ° C. for about 20 minutes to be evacuated for 20 minutes, and then taken out from the steam kettle.

  When the completed drape curtain 10 is spread on a desk, the separation width S shown in FIG. 2 is 11.1 to 11.2 cm, and the height H of each drape 11 is about 5 cm. The overall width was about 100 cm. Moreover, the width | variety of each superimposition part 10a was 5 cm. And when this drape curtain 10 was washed 8 times, the separation width S and height H were 11.1 cm and 5 cm, respectively, almost no change from the new state, and the laundry resistance was very high. It was. Of course, the width of each overlapping portion 10a remained at 5 cm.

  In particular, for the drape curtain 10 of the best mode, the drape S of each drape 11 when placed in a natural state is performed in the range of 7.8 to 15.5 cm, and the height H of the portion where the curved pleat is hung is set. In the range of 2.0 to 5.0 cm. The separation width (span) S of each drape 11 is set in the range of 7.8 to 15.5 cm. First, when this separation width S is smaller than 7.8 cm, each drape 11 can be clearly seen. This is because a curtain fabric having a special width (not normally provided) is required. On the other hand, when the separation width S is larger than 15.5 cm, not only does the body as the drape curtain 10 not be formed, but also when it is suspended on the curtain rail 20 by the latch 13, it becomes dull and beautiful. Because there will be no more.

  The height H of the portion of each drape 11 on which the curved pleats are hung is in the range of 2.0 to 5.0 cm. First, when the height H is lower than 2.0 cm, each valley fold pleating line 12 is Not only can it be permanent, but when such shallow valley fold pleated lines 12 are formed, the resulting “shadows” are thin and small, making it not possible to have a beautifully shaped drape 11. Because. On the other hand, if the height H of the portion of each drape 11 on which the curved pleats are hung is greater than 5.0 cm, not only is the curtain fabric required to have a special width, but also it is suspended from the curtain rail 20 by the latch 13. When it does, it becomes dull and loses its beauty.

  Further, in the vicinity of the upper end of the parallel fold pleating line 12a located in the immediate vicinity of each valley fold pleating line 12 and the overlapping part 10a, as shown in FIGS. A latch 13 for suspending the drape curtain 10 is attached to the curtain rail 20 provided at the top. In particular, the latch 13 attached in the vicinity of the upper end portion of the parallel folding pleating line 12a positioned in the immediate vicinity of the overlapping portion 10a prevents the overlapping portion 10a and the upper end of the drape 11 adjacent thereto from hanging down. It is. In addition, it is advantageous for each latch 13 to be attached about 5 mm below the upper end of the drape curtain 10 in order to attach the drape curtain 10 to the curtain rail 20 without a gap.

  FIG. 4 shows a partial front view of the drape curtain 10 according to the second embodiment. In the second embodiment, a fixing portion 16 is provided in each overlapping portion 10a. The fixing portion 16 may be various ones such as a hook-and-loop fastener, a magnet, a chuck, or a hook. In short, any fixing portion 16 may be used as long as the overlapping portions 10a can be fixed to each other. In this best mode, a plurality of partial surface fasteners are provided at the same position of each overlapping portion 10a and at portions that can face each other.

  FIG. 5 shows a partial cross-sectional view of the drape curtain 10 according to the third embodiment. In this third embodiment, by interposing the core material 10b in each overlapping portion 10a, The rigidity is a little larger than the other part of the drape curtain 10. As shown in FIG. 5, the core material 10b is most easily constituted by curtain fabric existing in the overlapping portion 10a by winding the fabric of the drape curtain 10 itself in the overlapping portion 10a. However, as described above, other materials may be used.

  Of course, if the core material 10b placed in the overlapping portion 10a is formed of a magnetized iron plate, the magnetic force of the core material 10b can exhibit a substantial function with the fixing portion 16 shown in the second embodiment. Therefore, it is advantageous in that the fixing portion 16 can be omitted and can be easily formed.

  FIG. 6 shows the drape curtain 10 according to the fourth embodiment. In this drape curtain 10, the curtain rail 20 is positioned near the latch 13 attached to the back surface side of the valley fold pleating line 12. A decorative material or decorative cloth 14 is attached to the front surface of the parallel position.

  That is, as shown in FIG. 6, the drape curtain 10 according to the fourth embodiment has a portion on the opposite side (room side) to each latch 13 when hanging the curtain curtain 20 with the latch 13. The decorative material or the decorative cloth 14 is attached, and the decorative material or the decorative cloth 14 can hide the constriction when the drape curtain 10 is used for a long period of time. It is.

  In general, when the curtain fabric constituting the drape curtain 10 is heavy or used for a long time, the gravity of the drape curtain 10 itself is directly applied to the vicinity of each latch 13, and each latch 13 There may be a slight “neck” in the vicinity. If the line due to the constriction is arranged in the horizontal direction corresponding to each position of the latch 13, it will not match the vertical drape 11 and the valley fold pleating line 12. For this reason, in the drape curtain 10 of the fourth embodiment, by attaching a decorative material or a decorative cloth 14 in advance to a portion where a line due to the constriction is likely to occur, This prevents the drape 11 and the valley fold pleating line 12 from feeling uncomfortable.

  The decoration material or decoration cloth 14 may be anything as long as it can conceal the above-mentioned constriction line and harmonizes with each drape 11 and valley fold pleating line 12, but it is a cloth with a volume such as a frill. It is effective to use a thick cloth that does not easily cause necking.

  Therefore, the drape curtain 10 according to the fourth embodiment prevents the constriction lines from appearing conspicuously even if there is a constriction line in the vicinity of each latch 13, and the beauty of each drape 11 and the valley fold pleating line 12 is maintained for a long time. It is something that can be maintained.

  7 and 8 show the drape curtain 10 according to the fifth embodiment. In this drape curtain 10, the drape curtain 10 is separated from each drape 11 and the overlapping portion 10a with the upper end interrupted. It is performed by the valley fold pleating line 12 and the parallel fold pleating line 12a formed in the vertical direction, and the curtain cloth located between the valley fold pleating lines 12 is curved on the opposite side to the valley pleating line 12. By applying the curved pleats, the cross section becomes a cycloid curve state, and further, the valley pleat dispersion line that spreads upward in the left and right directions at the upper ends of the valley fold pleating line 12 and the parallel fold pleating line 12a. By forming 15a, each valley fold pleating line 12 and parallel fold pleating line 12a In which was conducted so as to form a substantially dispersing section 15 of the triangle for dispersing the suspended gravity.

  As shown in an enlarged view in FIG. 8, each dispersion portion 15 is partitioned by a valley fold pleat dispersion line 15 a that extends upward from the upper end of each valley fold pleating line 12 to the left and right. As shown, it is a substantially inverted triangular shape. Each valley fold pleated dispersion line 15a is formed at the same time when pleating the valley fold pleated line 12, but may be the same "valley fold" as the valley pleated line 12, The reverse “mountain fold” may be used. And as shown by the dotted line in FIG. 8, each latch 13 is attached to the back surface of each dispersion portion 15, and the attachment position is most effective immediately above each valley fold pleating line 12. .

  Since such a dispersion portion 15 is positioned at the upper end of each valley fold pleating line 12, the force of forming the “neckline” due to the weight of the entire drape curtain 10 is changed by the both valley fold pleating dispersion line 15a. And is not concentrated on the latch 13 attached to the back surface of the dispersing portion 15. That is, no “neckline” is formed on the upper part of the drape curtain 10 by each dispersing portion 15.

  Therefore, the drape curtain 10 according to the fifth embodiment can also maintain the beauty of each drape 11 and the valley fold pleating line 12 over a long period of time.
