Description

Technical Field

[0001] The present invention relates to curtains.

Background Art

[0002] Conventionally, when looking at a curtain from the back side, the hook attachment member at the upper part of the curtain can be seen. Therefore, when used as a partition curtain, both sides of the curtain are easily visible to people's eyes, and the appearance of the upper part of the curtain deteriorates when viewed from the back side. Thus, it was necessary to hide the hook attachment member.

[0003] For example, in Patent Document 1, a curtain material is folded back three times with a predetermined length from the upper end, and a hook attachment member for attaching to a curtain runner is provided between the back surface of the first fold and the front surface of the third fold. An upper structure of a curtain capable of hiding the hook attachment member and a curtain using the same are disclosed. However, when comparing the first folded portion and the third folded portion at the upper part of the curtain, the hook attachment member is provided only in the third folded portion and not in the first folded portion. Therefore, when the curtain is used as a partition, it is assumed that there will be a difference in appearance between when viewed from the front side and when viewed from the back side. Also, in a patterned curtain, since the back surface of the curtain fabric is exposed when viewed from the back side of the curtain, the pattern of the curtain body and the pattern on the back side of the curtain cannot be matched.

[0004] A flat curtain itself has no folds and may be used in a flat state or may be used by forming waves by setting the width of the curtain fabric wider than the width of the curtain rail.

Summary of the Invention

[0006] The objective of this invention is to provide a curtain that can be used as a partition without compromising its appearance, as the hook attachment members are not visible when the top of the curtain is viewed from both the front and back sides. [Means for solving the problem]

[0007] [1] A flat curtain comprising a first sewing member and a second sewing member at the upper part of the back side of the curtain, The first sewing member has interlining A sewn in the width direction along the upper edge of the folded portion at the top of the curtain, and a plurality of hooks are attached to the interlining A at predetermined intervals in the width direction. The curtain is characterized in that the second sewing member is sewn along the lower end of the interlining A so as to cover the interlining A, and the interlining B is arranged inside the second sewing member.

[0008] [2] The curtain according to claim 1, wherein both ends in the width direction of the first sewing member and the second sewing member are sewn to at least a portion of the lower end of the interlining B in an upward direction. [Effects of the Invention]

[0009] According to the invention of [1], the second sewing member is sewn along the lower edge of the interlining A so as to cover the interlining A, not only when used as a regular curtain but also when used as a partition, so that the hook attachment member is not visible when viewed from either the front or back side of the curtain. Furthermore, the shape of the top of the curtain is maintained by the interlining A having a hook attachment member sewn to the first sewing member and the interlining B placed inside the second sewing member. As a result, the curtain has the same appearance when viewed from either the front or back side, and both sides can be used without compromising appearance, thus enabling effective utilization.

[0010] According to the invention of [2], both ends of the first sewing member and the second sewing member in the width direction are sewn to at least a portion of the lower end of the interlining B in an upward direction, so that the upper end of the curtain is less likely to bend or sag, and the appearance is improved. Furthermore, since the remaining portions at both ends of the first and second sewing members in the width direction are open (not sewn), it is easy to attach hooks to the curtain rail. [Brief explanation of the drawing]

[0011] [Figure 1] This diagram shows the first sewing member of the present invention as viewed from the interlining A side. [Figure 2] This diagram shows the first sewing member of the present invention as viewed from the surface of the curtain. [Figure 3] This diagram shows a strip of fabric in which interlining B is installed inside the second sewing member of the present invention. [Figure 4] This shows the seam where the first sewing member and the second sewing member of the upper part of the curtain of this invention are sewn together. [Modes for carrying out the invention]

[0012] Hereinafter, embodiments of the present invention will be described based on the drawings.

[0013] Figure 1 shows the first sewing member (10) as seen from the back (3) of the curtain body of this invention. The first sewing member (10) is attached to the folded-over portion (4) at the top of the curtain by sewing the upper part of interfacing A (6), to which a hook attachment member (5) is attached, with a seam allowance (8), and the lower part is further sewn with an interlock stitch (9). Interfacing A (6) with a width of 80 mm is used for the first sewing member (10). A hook is attached to the hook attachment member (5), but the hook is omitted in Figure 1. A G hook is selected to minimize interference with the second sewing member (11). Either a transparent PET G hook for gathering or a white POM G hook for gathering may be used.

[0014] Figure 2 shows the first sewing member (10) as seen from the front (2) of the curtain body, with the top and bottom edges of the interlining A (6) sewn to the folded-over portion (4) at the top of the curtain body with seam allowances (8).

[0015] Figure 3 shows a strip of fabric with interlining B (7) installed inside the second sewing member (11). The second sewing member (11) is made of the same fabric (15) as the curtain body (1), has 75 mm wide interlining B (7) built inside, and the edges are sewn with a 5 mm triple fold using a seam allowance (8).

[0016] Figure 4 shows the seam between the first sewing member (10) and the second sewing member (11). The first sewing member (10) and the second sewing member (11) are aligned at the top, and the bottoms of the first sewing member (10) and the second sewing member (11) are sewn together with a seam allowance (8). In the width direction of the curtain, the ends (12) of the first sewing member and the ends (13) of the second sewing member are sewn together with a seam allowance (8) along the top of the bottom of the interlining B (7), at least to a portion of the way. Since both ends of the first sewing member (10) and the second sewing member (11) in the width direction are sewn to the interlining B (7) from the bottom edge upwards to at least a portion of it, the top edge of the curtain is less likely to bend or sag, resulting in a better appearance. Furthermore, since the remaining portions of both ends of the first sewing member (10) and the second sewing member (11) in the width direction are not sewn with seam allowances (8), the opening (14) at the top of the curtain can be easily widened, and the hooks can be easily attached to the curtain rail.

[0017] The pattern on the front (2) of the curtain body and the second sewing component (11) can be matched, and the upper edge of the second sewing component (11) is sewn so that it does not protrude from the upper edge of the first sewing component (10), making it possible to make the curtain look the same as the front side, with the hook attachment component (5) not visible from either the front or back side. In addition, it is possible to use different colors or designs for the fabric on the front (2) of the curtain body and the fabric of the second sewing component (11), and when the curtain is viewed from the back side, the second sewing component (11) can be used as an accent.

[0018] Sew the first sewing member (10) and the second sewing member (11), or attach hooks to the second sewing member (11) and hook the hooks on the fabric A (6) with a hook attachment member (5) of the first sewing part (10) for use, so that the second sewing member (11) may be removable.

Example

[0019] The first sewing member (10) was sewn at the upper part of the flat-dedicated fabric A (6) made of Unitec Paroma with a width of 80 mm with a hook attachment member (5) attached to the folded part (4) at the upper part of the curtain, and the lower part was sewn by an interlock stitch (9). For the second sewing member (11), a fabric B (7) with a width of 75 mm was used. The first sewing member (10) and the second sewing member (11) were aligned at the upper part, and the lower parts of the first sewing member (10) and the second sewing member (11) were sewn together and sewn by a straight stitch. The ends (12) of the first sewing member and the ends (13) of the second sewing member in the width direction of the curtain were sewn up to 35 mm along the upward direction from the lower part of the fabric B (7). The hooks used were G hooks for gathering made of Unitec Paroma.

[0020] As an evaluation of the example, when the curtain was viewed from both the front side and the back side, since the fabric A (6) was attached to the first sewing member (10) and the fabric B (7) was installed inside the second sewing member (11), the shape of the upper part of the curtain was maintained regardless of the thickness of the fabric, and the appearance of the front side and the back side of the curtain was not deteriorated.

Industrial Applicability

[0021] The present invention relates to a curtain that can be used for partitions that can be used without inferiority on both sides of the curtain in terms of appearance. In addition to using one side as a flat curtain, it can be used as a curtain that can be used on both sides as a partition for offices, public facilities, etc.
