Description

[Technical Field]

[0001] The present invention relates to curtains. [Background technology]

[0002] Curtains are made from a single piece of fabric and are sold as ready-made products with fixed length and width. Ready-made curtains may not be able to be installed due to dimensional constraints. In contrast, semi-custom-made curtains are also sold, allowing customers to specify the length and width. Even with these semi-custom-made curtains, when the ordered product arrives and is installed, it can sometimes happen that the size does not fit due to errors in measurement, etc. This has led to a demand for curtains that can be easily adjusted in size, and proposals in this regard have been made. For example, Patent Document 1 discloses a length-adjustable curtain that has a curtain body with a pile-like structure on part or all of the pattern on the surface, and a length-adjustable cloth with adhesive tape sewn onto the backside that is detachably attached.

[0003] [Patent Document 1] Utility Model Registration No. 3086450 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the length-adjustable curtain of Patent Document 1 has a problem in that the adjustment part is a separate body, and therefore a step is created when the curtains are connected, which mars the aesthetic appearance.

[0005] SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a curtain whose length can be easily adjusted without spoiling the aesthetic appearance. [Means for solving the problem]

[0006] In order to solve the above problems, the curtain of the present invention is characterized in that it comprises a long strip-shaped member on the curtain lining near the bottom of the curtain, the length of which is in the width direction of the curtain body, and a hook-and-loop fastener on the surface of the strip-shaped member that engages with the curtain lining, and when the bottom of the curtain is folded back at any position, the hook-and-loop fastener engages with the curtain lining to maintain the folded-back state.

[0007] Here, it is preferable that the curtain lining further comprises a second elongated belt-shaped member having a length in the width direction of the curtain body and parallel to the belt-shaped member, and that the hook-and-loop fastener is also provided on the surface of the second belt-shaped member.

[0008] It is further preferable that the second belt-shaped member has a hook-and-loop fastener on the back surface thereof that engages with the curtain lining, and that the second belt-shaped member is detachably attached to the curtain lining.

[0009] It is also preferable that the curtain fabric be made up of a curtain lining, a curtain outer material, and a sheet-like member made of thermoplastic resin interposed between them.

[0010] Furthermore, it is preferable that the curtain body has pleated portions at predetermined intervals in the width direction, and that the belt-shaped member has an adhesive portion on which a hook-and-loop fastener that engages with the curtain lining is formed, and a non-adhesive portion on which the hook-and-loop fastener is not formed, and that the position of the pleated portions coincides with the position of the non-adhesive portion on the belt-shaped member. [Effects of the Invention]

[0011] According to the curtain of the present invention, when the curtain is folded back at any position, the hook-and-loop fastener attached near the bottom of the curtain engages with the curtain lining and fixes the bottom of the curtain in the folded-back state, thereby realizing a curtain whose length can be easily adjusted without creating a step or spoiling the aesthetic appearance.

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A curtain according to the present invention will be described below based on an embodiment.

[0014] FIG. 1 is a diagram showing the lower end of a curtain according to a first embodiment of the present invention.

[0015] The curtain 1 of the first embodiment is a curtain made of a single piece of fabric, and is provided with a hook-and-loop fastener part 21 at the curtain bottom part 12 of the curtain lining 11.

[0016] The curtain bottom 12 is the edge of the lower end of the curtain 1, that is, the bottom of the curtain 1, and a hook-and-loop fastener part 21 is removably attached near this bottom.

[0017] The hook-and-loop fastener section 21 is a strip-shaped member having a length in the width direction of the curtain 1 body and configured as a hook-and-loop fastener to be attached to the curtain lining 11 near the curtain bottom 12. The hook-and-loop fastener section 21 is configured by arranging hook-and-loop fasteners on both sides of the strip-shaped member, with a hook-and-loop fastener on the back side for attaching to the curtain lining 11 and a hook-and-loop fastener on the front side for securing the bottom of the curtain 1 in the folded-over state when it is folded back. If the curtain lining 11 is made of a brushed tricot material, both sides of the hook-and-loop fastener section 21 will have hook surfaces (male) that engage with the brushed tricot's loop surfaces (female). It is also acceptable to configure the curtain lining 11 to have a hook surface and the hook-and-loop fastener section 21 to have a loop surface.

[0018] FIG. 2 is a diagram showing a state in which the lower end of the curtain according to the first embodiment is folded back.

[0019] When the curtain 1 is folded back at any position (fold-back line 13), the hook-and-loop fastener part 21 attached to the curtain lining 11 near the curtain bottom 12 engages with the curtain lining 11 and fixes it in the folded-back state, thereby making it possible to adjust the length of the curtain 1. In other words, the hook-and-loop fastener part 21 functions as a long fixing device that fixes the bottom of the curtain 1 in the folded-back state, making it possible to adjust the vertical length of the curtain 1.

[0020] Here, the hook-and-loop fastener portion 21 may be fixedly attached to the curtain lining 11 near the curtain bottom 12, or may be detachably attached. When the hook-and-loop fastener portion 21 is detachably attached to the curtain lining 11, it is preferable to set the bonding strength of the opposite surface (the back surface of the hook-and-loop fastener portion 21) to be stronger than the surface (the front surface of the hook-and-loop fastener portion 21) that functions as a fastener for fixing the folded-over state. This is to prevent the back surface of the hook-and-loop fastener portion 21 from peeling off from the curtain lining 11, which is necessary when releasing the folded-over state of the curtain 1.

[0021] Furthermore, the hook-and-loop fastener portion 21 may have the same length as the width of the curtain 1 body, or multiple hook-and-loop fastener portions 21 of a fixed length may be provided intermittently in the width direction of the curtain 1. If the hook-and-loop fastener portion 21 is to be detachable from the curtain lining 11, the hook-and-loop fastener portion 21 can be divided into multiple pieces and attached in the width direction of the curtain 1, which has the advantage of facilitating attachment and detachment. Note that if multiple fasteners are spaced apart, the greater the number of fasteners, the more difficult it becomes to keep the fold line 13, which is the placement position, horizontal. As a result, the fold cannot be kept horizontal, which results in a poor appearance. For this reason, it is preferable that the hook-and-loop fastener portion 21 be a long fastener with a fixed length rather than a short fastener.

[0022] FIG. 3 is a diagram schematically showing the fabric constituting the curtain according to the first embodiment.

[0023] The fabric that makes up the curtain 1 has a three-layer structure consisting of a curtain outer fabric 10, a curtain lining 11, and a middle layer TPU sheet 14. The middle layer TPU sheet 14 is a sheet-like member made of a thermoplastic resin such as thermoplastic polyurethane (TPU).

[0024] These layers are bonded together with adhesive 15, such as a hot melt adhesive, and the interposition of the intermediate TPU sheet 14 improves the adhesive strength between the curtain outer fabric 10 and the curtain lining 11. The interposition of the TPU sheet 14 prevents the fabric from being seen through, providing a shielding effect and also providing heat insulation.

[0025] The reason for interposing the TPU sheet 14 as an intermediate layer to increase the adhesive strength between the curtain outer fabric 10 and the curtain lining 11 is as follows: The hook-and-loop fastener portion 21 is attached to the curtain lining 11, thereby securing the bottom of the curtain 1 in a folded-over state. When releasing this securing, i.e., when peeling the hook-and-loop fastener portion 21 from the curtain lining 11, pulling one end of the curtain 1 may cause the adhered curtain outer fabric 10 and curtain lining 11 to peel away from each other. Furthermore, if this action is repeated, the adhesive strength between the curtain outer fabric 10 and the curtain lining 11 weakens, making them more susceptible to peeling. For this reason, the TPU sheet 14 as an intermediate layer is interposed as an element that aids in the adhesion between the curtain outer fabric 10 and the curtain lining 11, and the entire surface of the sheet is bonded to the curtain lining 11, thereby increasing the adhesive strength between the curtain outer fabric 10 and the curtain lining 11.

[0026] The fabric that constitutes the curtain 1 is formed in the following manner.

[0027] A hot melt adhesive (PUR) is applied to one side of the curtain outer fabric 10, and then the surface with the hot melt adhesive and a TPU sheet 14 are bonded together while applying heat with a roller. Next, the hot melt adhesive is applied to one side of the curtain lining 11. The bonded curtain outer fabric 10 and TPU sheet 14 are bonded together with the surface of the curtain lining 11 with the hot melt adhesive applied, and they are bonded together while applying heat with a roller.

[0028] Thus, according to the curtain of embodiment 1, when the curtain 1 is folded back at any position, the hook-and-loop fastener part 21 attached near the bottom of the curtain lining 11 engages with the curtain lining 11, fixing the bottom of the curtain 1 in the folded-back position. In other words, because the hook-and-loop fastener part 21 of the length adjuster and the curtain lining 11 that constitutes the curtain body are integrated, the vertical length can be adjusted by changing the folding position at any time without creating any step or spoiling the aesthetic appearance.

[0029] Next, a description will be given of a curtain according to embodiment 2. The description will focus on the differences from embodiment 1, and the same components will be given the same reference numerals and the description thereof will be omitted.

[0030] FIG. 4 is a diagram showing the lower end of the curtain according to the second embodiment.

[0031] The curtain 2 of embodiment 2 differs from the curtain 1 of embodiment 1 in that a hook-and-loop fastener portion 22, which is a long fastener similar to the hook-and-loop fastener portion 21, is attached near the fold line 13, parallel to the hook-and-loop fastener portion 21 attached near the curtain bottom 12 of the curtain lining 11.

[0032] By providing a hook-and-loop fastener part 22 at any position of the fold, that is, below the fold line 13 which is the line along which the fold is to be made, and also near the fold line 13, the bottom of the curtain 2 after being folded can be kept flat, as will be described later, thereby maintaining a good appearance.

[0033] FIG. 5 is a diagram showing a state in which the bottom end of the curtain according to the second embodiment is folded back, and FIG. 6 is a side view of the state in which the bottom end of the curtain according to the second embodiment is folded back.

[0034] When the curtain 2 is folded back at the folding line 13, the hook-and-loop fastener part 21 attached to the curtain lining 11 near the curtain bottom 12 engages with the curtain lining 11 and fixes it in the folded-back state. Also, the hook-and-loop fastener part 22 attached near the folding line 13 engages with the curtain lining 11 at the folded-back portion and fixes that portion in the folded-back state.

[0035] At this time, if the folded bottom of the curtain 2 is fixed only at the engagement point between the hook-and-loop fastener part 21 and the curtain lining 11, the folded portion located near the folding line 13 may bulge. By attaching the hook-and-loop fastener part 22 near the folding line 13, the bulge of the folded portion located near the folding line 13 is suppressed and this part is kept flat, so that the appearance of the bottom of the curtain 2 after folding can be maintained in a good condition.

[0036] Thus, according to the curtain of this embodiment 2, the hook-and-loop fastener portion 22 attached below and near any folding position of the curtain 2 engages with the curtain lining 11 and fixes the folding portion in the folded state, thereby keeping the bottom of the curtain 2 flat after folding, thereby achieving an excellent aesthetic appearance.

[0037] Here, two hook-and-loop fastener sections for fixing the folded state are shown: hook-and-loop fastener section 21 attached near the curtain bottom 12 of the curtain lining 11, and hook-and-loop fastener section 22 attached near the fold line 13; however, it is sufficient to have hook-and-loop fastener sections for fixing at least these two points, and multiple hook-and-loop fastener sections may be provided between these two points.

[0038] Furthermore, the hook-and-loop fastener part 21 may be fixedly attached to the curtain lining 11 near the curtain bottom 12, and the hook-and-loop fastener part 22 may be detachably attached to any position on the curtain lining 11 parallel to the hook-and-loop fastener part 21, so that the folding position of the curtain 2 can be changed at any position, and flexible length adjustment in the vertical direction is possible.

[0039] Next, a description will be given of a curtain according to embodiment 3. The description will focus on the differences from embodiments 1 and 2, and the same components will be given the same reference numerals and descriptions thereof will be omitted.

[0040] FIG. 7 is a diagram showing the lower end of the curtain according to the third embodiment, and FIG. 8 is a diagram showing the pleats of the curtain according to the third embodiment as viewed from below.

[0041] In the curtain 3 of the third embodiment, a belt-shaped member 31 is attached to the curtain lining 11 near the curtain bottom 12 , and a second belt-shaped member 32 is attached to the curtain lining 11 near the fold-back line 13 .

[0042] The belt-shaped member 31 and the second belt-shaped member 32 are fixing devices having the same function as the hook-and-loop fastener portion of the first and second embodiments, and are common in that the belt-shaped member 31 has the same effect as the hook-and-loop fastener portion 21 in the first and second embodiments, and the second belt-shaped member 32 has the same effect as the hook-and-loop fastener portion 22 in the second embodiment.

[0043] On the other hand, the belt-shaped member 31 and the second belt-shaped member 32 differ in configuration from the hook-and-loop fastener portion 21 and the hook-and-loop fastener portion 22. The belt-shaped member 31 and the second belt-shaped member 32 have the same configuration except for the position where they are arranged, so only the belt-shaped member 31 will be described below.

[0044] The belt-shaped member 31 is a long belt-shaped member having a length corresponding to the width direction of the curtain 3 body, and has front adhesive portions 33, non-adhesive portions 34, and back adhesive portions 35 alternately in the length direction.

[0045] The surface adhesive portion 33 is a hook-and-loop fastener that engages with the curtain lining 11 when the bottom of the curtain 3 is folded back, thereby maintaining the folded state.

[0046] The adhesive backing 35 is a hook-and-loop fastener that engages with the curtain lining 11 to attach the belt-shaped member 31 to the curtain lining 11 .

[0047] It is preferable to provide a difference in the adhesive strength of the hook-and-loop fasteners of the front adhesive portion 33 and the back adhesive portion 35 so that the adhesive strength of the back adhesive portion 35 is stronger than that of the front adhesive portion 33. This is to prevent the back adhesive portion 35 from peeling off from the curtain lining 11 when the front adhesive portion 33 is peeled off from the curtain lining 11 to release the folded-back state of the curtain 3.

[0048] The non-adhesive portions 34 are provided intermittently with a predetermined regularity in the portions of the belt-shaped member 31 where the hook-and-loop fasteners, which are the two adhesive portions of the front adhesive portion 33 and the back adhesive portion 35, are not formed and the portions are free from the curtain lining 11. The predetermined regularity here refers to intervals that match the intervals of the pleats 16 in the curtain 3.

[0049] Some curtains are formed with wavy pleats (drapes) by bending the width direction of the curtain at regular intervals. In the curtain 3 of the third embodiment, the belt-shaped member 31 is arranged so that the non-adhesive portion 34 is positioned to match the position of the pleats 16 formed on the curtain 3. In this case, it is preferable to provide the non-adhesive portion 34 so that the drape line 17, which is the bending line of the pleats 16, is positioned in the center of the non-adhesive portion 34.

[0050] When the elongated fastener is engaged with the curtain lining 11 via a hook-and-loop fastener across the entire width, i.e., when the entire elongated fastener is attached to the curtain lining 11, in a draped curtain, the draped portion may not be folded back sufficiently when the bottom of the curtain is folded back, resulting in a poor appearance of the folded curtain. Therefore, the belt-shaped member 31 is configured so that two adhesive portions and a non-adhesive portion 34 are alternately arranged to match the spacing between the pleats 16. Furthermore, when attached to the curtain 3, the non-adhesive portion 34 is aligned with the pleats 16 of the curtain 3. This maintains the pleats 16 in their natural pleated form when the bottom of the curtain 3 is folded back, thereby preventing a loss of appearance. Furthermore, the alternating arrangement of the two adhesive portions and the non-adhesive portion 34 also helps maintain the flexibility of the curtain 3 in the width direction.

[0051] At the pleats 16 of the curtain 3, the non-adhesive portions 34 of the belt-shaped member 31 are separated from the pleats 16. When the pleats 16 are folded back at a certain position, the non-adhesive portions 34 are separated from the pleats 16, so the pleats are naturally folded back without affecting the structure of the pleats 16, and the appearance of the bottom of the curtain 3 after folding back is not marred.

[0052] Thus, according to the curtain of the third embodiment, belt-shaped members 31, each having two adhesive portions, front adhesive portion 33 and back adhesive portion 35, and non-adhesive portion 34, arranged alternately, are attached near the bottom of the curtain lining 11 and below and near the folding line 13 of the curtain 3 to match the spacing of the pleats 16, and the non-adhesive portion 34 is configured to match the position of the pleats 16, so that when the bottom of the curtain 3 is folded back, the bottom of the curtain 3 folded back at the pleats 16 in the folded part can be folded back naturally while maintaining its pleated shape. As a result, a curtain can be realized that can be folded without compromising its appearance and whose length can be adjusted.

[0053] The intervals at which the pleats 16 are formed vary depending on the design of the curtain 3, which results in different lengths of the two adhesive portions and the non-adhesive portion 34. Even in this case, it is preferable to ensure that the two adhesive portions are longer than the non-adhesive portion 34 relative to the overall length of the belt-shaped member 31, thereby ensuring adhesive strength to fix the folded state.

[0054] Alternatively, a belt-shaped member 31 located near the curtain bottom 12 of the curtain lining 11 may be fixedly attached to the curtain lining 11, and a second belt-shaped member 32 may be detachably attached to any position on the curtain lining 11 parallel to the belt-shaped member 31, thereby allowing the folded position of the curtain 3 to be changed as desired and enabling flexible adjustment of the vertical length. In this case, only the second belt-shaped member 32 has an adhesive backing 35, and the belt-shaped member 31 is attached to the curtain lining 11 by sewing or the like instead of the adhesive backing 35.

[0055] The curtains according to the present invention have been described above based on various embodiments, but the present invention is not limited to these. Various design modifications are possible as long as the object of the present invention can be achieved and the modifications do not deviate from the gist of the invention, and all of these modifications are included within the scope of the present invention.

[0056] For example, in the above embodiment, the hook-and-loop fastener is attached to the curtain lining, but the hook-and-loop fastener may be provided on the curtain outer surface side and the curtain outer surface side folded back. Although a configuration in which the curtain lining side is folded back can be said to be preferable in terms of pursuing a better aesthetic appearance, this is not intended to exclude a configuration in which the curtain outer surface side is folded back. [Industrial Applicability]

[0057] The curtain according to the present invention is suitable for use as a curtain whose length is adjustable. [Explanation of symbols]
