Description

Technical field

[0001] The present invention relates to a product with an attached zipper. State of the art

[0002] International Publication No. 2011 / 064893 (PTL 1), for example, describes a zipper with waterproof properties. In short, the zipper described in PTL 1 comprises a pair of left and right zipper pulls with rows of elements formed on them, and a slider that is slidably attached to the left and right rows of elements.

[0003] Each of the left and right zipper pulls comprises a zipper tape (tape element) and a multitude of zipper elements positioned along one side edge of the zipper tape. The zipper tape includes a narrow tape body, which is, for example, waterproof, and a core strand positioned along one side edge of the tape body. The zipper tape has properties that prevent liquid from penetrating from one side of the zipper tape to the other. List of citations from patent literature

[0004] PTL 1: International Publication No. 2011 / 064893 Summary OF THE INVENTION Technical Problem

[0005] To attach the zipper described in PTL 1 to a product, for example a garment or a bag, the zipper tape of each zipper carrier and a zipper receiving element of the product (for example a piece of fabric of a garment) are stacked on top of each other and subjected to a sewing process carried out by a sewing machine.

[0006] In the prior art sewing method, the zipper tape and a section of the zipper mounting element, to which the zipper is to be attached, are typically placed one on top of the other and inserted into a space between a needle plate and a presser foot of the sewing machine in order to sew the zipper tape and the zipper mounting edge together. In this case, due to the positional relationship between the presser foot, the sewing needle, and the zipper elements of the zipper holder, the sewing machine needle must move up and down during the sewing process and be inserted through the zipper tape at a point that is spaced apart from the zipper elements of the zipper tape in the direction of the tape width.This creates a sewn section, formed from a single thread used to sew the zipper tape and the zipper tape attachment together, at a position that is spaced away from the zipper tape attachments in the direction of the tape width. Therefore, the zipper tape is exposed to the outside in an area between the zipper tape attachment and the zipper tape attachments.

[0007] If the zipper tape is exposed in the area between the zipper receiver and the zipper teeth as described above, the product with the zipper attached cannot be made waterproof, unless both the zipper tape and the fabric piece serving as the zipper receiver are waterproof, as described in PTL 1. However, manufacturing a waterproof zipper tape requires special equipment or materials, which increases manufacturing costs and complicates the manufacturing process.

[0008] When a zipper is attached to a product, it is considered an element of the product design. Therefore, any zipper tape should preferably be invisible or less visible in order to improve the design or visual quality of the product with the zipper attached.

[0009] The present invention was made taking into account the problem described above and aims to enable each zipper tape and a corresponding zipper receiving element to be easily sewn together and to prevent or reduce the exposure of the zipper tape in an area between the zipper receiving element and the zipper elements, thereby providing a product with an attached zipper that can have improved waterproofness and an improved design or appearance. Solution to the problem

[0010] To achieve the above-described objective, a product with an attached zipper according to the present invention comprises a pair of zipper carriers and a zipper receiving element. Each zipper carrier comprises a zipper tape and a plurality of zipper elements arranged at equal intervals along the length of the zipper tape. The zipper receiving element comprises a pair of carrier attachment edges to which the zipper carriers are attached and which are positioned opposite each other. Each zipper carrier is attached to a corresponding carrier attachment edge by a sewn section formed from a sewing thread. Each carrier attachment edge comprises a double-layered section that, in a sectional view along a plane perpendicular to the tape's longitudinal direction, is bent in a U-shape.The double-layered section comprises a first strip section, a curved section, and a second strip section in the sectional view. The first strip section is spaced away from the zipper tape. The curved section extends from the first strip section and has a curved shape. The second strip section extends from the curved section and overlaps the first strip section. A portion of the sewn section is positioned between the first and second strip sections of the double-layered section. The sewn section is positioned away from the multitude of zipper elements, and the curved section is in contact with or near the multitude of zipper elements. A waterproof area is formed between the sewn section and the multitude of zipper elements.

[0011] In the product with attached zipper according to the present invention, the curved section is preferably located away from the sewn section and in contact with the zipper elements.

[0012] In this case, the zipper tape and the second strip section are preferably connected to each other in at least part of an area between the curved section and the sewn section.

[0013] In addition, the curved section is preferably designed in such a way that the curved shape of the curved section is retained by heat treatment.

[0014] Additionally, the sewn section is preferably spaced away from the zipper elements by a distance of 0.5 mm or more and 10.0 mm or less in one width direction of the zipper tape.

[0015] Additionally, a distance of 0.25 mm or more and 5.0 mm or less is preferably maintained between an outer surface of the first strip section of the double-layered section and an outer surface of the second strip section of the double-layered section in a tape thickness direction of the zipper tape.

[0016] In the product with attached zipper according to the present invention, the curved section is preferably located near a position where the sewn section is formed and near the plurality of zipper elements in a left-right direction, and the sewn section is spaced from the zipper elements by a distance of 0.5 mm or more and 3.0 mm or less in a width direction of the zipper tape.

[0017] In the above-described product with attached zipper according to the present invention, each of the zipper elements preferably comprises an element base and a wing section, wherein the element base comprises a section with a constant dimension in a tape thickness direction of the zipper tape, wherein the wing section extends from the element base to an inner region of the zipper tape and has a dimension that is smaller than the dimension of the element base in the tape thickness direction. Advantageous effects of the invention

[0018] According to the product with attached zipper of the present invention, the exposure of the zipper tape in the area between the zipper receiving element and the zipper elements can be prevented or reduced, so that the waterproofness can be increased and the design or appearance quality can be improved.

Description of the embodiment

[0019] The applicant has filed a PCT application (PCT / JP2022 / 032020) for a product with an attached zipper, manufactured by sewing zipper tapes from zipper carriers to carrier attachment edges of a zipper receiving element and characterized by interlocking sections of sewn sections. According to the technology described in this PCT application, the exposure of each zipper tape in an area between the corresponding zipper receiving element (fabric piece) and the zipper elements can be prevented or reduced by bringing the corresponding sewn section into contact with the zipper elements.

[0020] In contrast, in products with an attached zipper, the exposure of a zipper tape in an area between a zipper attachment element (fabric piece) and the zipper elements can be prevented or reduced without bringing a sewn section into contact with the zipper elements. The sewn section, as described in the PCT application above, is formed from sewing threads comprising a top thread and a bobbin thread of a sewing machine. In this case, the sewing threads used to form the sewn section can be water-repellent. In such a case, the water resistance of the zippered product can be further increased.

[0021] Preferred embodiments of the present invention will now be described in detail with reference to the drawings and examples. Design 1

[0022] Fig. Figure 1 is a schematic top view of a product with an attached zipper according to embodiment 1. Fig. 2, Fig. 3 and Fig. Figure 4 is an enlarged schematic perspective view, an enlarged schematic bottom view, and an enlarged schematic sectional view of a part of the product with a zipper attached.

[0023] In the following description of a zipper and the product with an attached zipper, the front and back directions are directions along a longitudinal direction of each zipper tape and correspond to a direction along which a slider slides (see Fig. 1 and Fig. 2) The direction in which the slider moves to close the zipper is called forward, and the direction in which the slider moves to open the zipper is called backward.

[0024] The left-right direction is a direction along the width of each zipper tape, more precisely a direction orthogonal to the front and back and parallel to a front and a back surface of the zipper tape. The left-right direction can also be considered the direction in which rows of elements of a pair of zipper pulls engage with and disengage from each other. In this case, the direction in which the pair of element rows is brought closer together is referred to as inward along the left-right direction, and the direction in which the pair of element rows is moved away from each other is referred to as outward along the left-right direction (see Fig. 3).

[0025] A top and bottom direction is a direction orthogonal to the front and back of each zipper tape (tape front and back direction) and is a direction orthogonal to the front and back direction and to the left and right direction (see Fig. 4) The top and bottom direction can also be referred to as the tape thickness direction. In this case, the direction in which the zipper points outwards when in use (for example, the direction from the zipper tape to a pull tab of the slider) is referred to as the upward direction, and the opposite direction is referred to as the downward direction.

[0026] A product with an attached zipper 1 of embodiment 1 is, for example, a garment (clothing product), and a zipper 20 is attached, for example, to the front opening sections of the front parts of the garment and to the opening and closing sections (opening edges) of pockets provided on the chest and waist sections of the front parts. The garment 1 with zipper comprises the zipper 20 and one or more zipper receiving elements 10. The zipper 20 comprises a pair of left and right zipper pulls 21. The zipper receiving elements 10 comprise left and right pull attachment edges 11 to which the left and right zipper pulls 21 are attached.

[0027] In embodiment 1, the zipper receiving elements 10, to which the zipper 20 is attached, are fabric pieces 10 of a garment (also referred to as garment fabric pieces). Each of the left and right fabric pieces 10, which form the fronts of the garment, comprises a side edge 11 facing the other fabric piece 10. The facing side edges 11 of the left and right fabric pieces 10 serve as carrier attachment edges 11, to which the zipper pulls 21 of the zipper 20 are attached.

[0028] In embodiment 1, the left and right fabric pieces 10, including the support fastening edges 11, are at least watertight. The watertight fabric pieces 10 have properties that reduce the penetration or ingress of water. In embodiment 1, the method or device for making the fabric pieces 10 watertight is not particularly restricted. Furthermore, it is not necessary for the fabric pieces 10 to be watertight.

[0029] Each of the left and right fabric pieces 10 comprises a fabric body (not shown) and the support attachment edge 11, which is provided on one edge of the fabric body. The support attachment edge 11 of each fabric piece 10 has the corresponding zipper carrier 21, which is attached to it by a sewn section 12 formed from sewing threads (threads of a sewing machine).

[0030] As in Fig. As shown in Figure 4, the carrier attachment edge 11 of each fabric piece 10 comprises a double-layered section 14 in which sections of the fabric piece 10 of the garment overlap in the upper and lower directions. The double-layered section 14 of the carrier attachment edge 11 is formed by bending the fabric piece 10 of the garment along a curved section 16 extending in the front and back directions, thus having a U-shape in a section along a plane orthogonal to the front and back directions. In this case, the double-layered section 14 is in contact with wing sections 23b (second wing sections 25b) of zipper elements 23, which are described below.

[0031] In the sectional view along the plane perpendicular to the front and back directions, the double-layered section 14 comprises a first strip section 15 extending inwards along the width direction from the fabric body (not shown), the curved section 16 which is curved and extends from the first strip section 15, and a second strip section 17 which extends from the curved section 16 and is arranged overlapping in the first strip section 15 in the upper and lower directions.

[0032] In the double-layered section 14, the first strip section 15 is arranged above the second strip section 17 and spaced apart from a zipper tape 22 of the zipper carrier 21 described below. The second strip section 17 is in contact with the zipper tape 22. The second strip section 17 is positioned between the zipper tape 22 and the first strip section 15 in the upper and lower directions. The curved section 16 is arranged away from the sewn section 12 in the left and right directions towards the inner area of ​​the zipper 20 and is closer to the zipper elements 23 described below than the sewn section 12.

[0033] The double-layered section 14 has inner surfaces, which are mutually facing surfaces of the fabric piece 10, and outer surfaces, which face away from the inner surfaces. In this case, the inner surfaces of the double-layered section 14 comprise the underside of the first strip section 15, an inner circumferential surface of the curved section 16, and the top side of the second strip section 17. The outer surfaces of the double-layered section 14 comprise the top side of the first strip section 15, an outer circumferential surface of the curved section 16, and the underside of the second strip section 17. The underside of the second strip section 17 can also be considered a surface facing the zipper tape 22.

[0034] The support attachment edge 11 of the fabric piece 10 and the zipper support 21 are sewn together to form the sewn section 12 in a single straight stitch using a sewing machine (not shown). The sewn section 12 extends straight in the front and back direction of the zipper tape 22 (see Fig. 3) This sewn section 12 is formed from sewing threads comprising an upper thread (needle thread) and a lower thread (weft thread) of the sewing machine. The sewing threads forming the sewn section 12 may be water-repellent.

[0035] The straight sewn section 12 connects the second strip section 17 of the double-layered section 14 and the zipper tape 22, thereby attaching the zipper carrier 21 to the carrier attachment edge 11 of the fabric piece 10. In the present invention, the sewn section connecting the carrier attachment edge and the zipper carrier can comprise a section that is slightly bent or curved inwards or outwards in the left and right directions.

[0036] The sewn section 12 of embodiment 1 is separated from the zipper elements 23 in the left and right directions (towards an inner area of ​​the zipper tape 22) and also separated from the curved section 16 of the support mounting edge 11 in the left and right directions. The curved section 16 of the support mounting edge 11 is in contact with the zipper elements 23, and a portion of the double-layered section 14 between the sewn section 12 and the curved section 16 in the left and right directions serves as a flap over the zipper tape 22. In this way, a watertight area is formed between the sewn section 12 and the zipper elements 23.

[0037] In this case, the separation distance between the sewn section 12 and the wing section 23b of each zipper element 23, described below in the left and right directions, is preferably 1 mm or more and 10.0 mm or less. If the distance is 1 mm or more, a first adhesive layer 31, as described below, can be reliably applied between the zipper tape 22 and the carrier attachment edge 11. If the distance is 10.0 mm or less, the zipper tape 22 and the second strip section 17 can be prevented from having excessively large widths (dimensions in the left and right directions). This can reduce the manufacturing costs of the garment 1 with the attached zipper. If the distance is greater than 10.0 mm, it can be difficult to form the curved section 16 at a position where the curved section 16 is in contact with the zipper elements 23.

[0038] A portion of the sewn section 12 of embodiment 1 is arranged between the first strip section 15 and the second strip section 17. In other words, a portion of the sewn section 12 is surrounded by the double-layered section 14. The portion of the sewn section 12 that is arranged between the first strip section 15 and the second strip section 17 is a portion of the sewn section 12 that is located on the upper side of the second strip section 17.

[0039] In the product with attached zipper 1 of embodiment 1, the first adhesive layer 31 is provided between the front (surface) of the zipper tape 22 and the underside of the second strip section 17 to bond the zipper tape 22 and the double-layered section 14 together. The first adhesive layer 31 is preferably provided between the zipper tape 22 and the second strip section 17 at least at one position near the zipper elements 23 in the left and right directions. For example, in embodiment 1, the first adhesive layer 31 extends continuously in the left and right directions over an area from a position at (or near) the boundary between the curved section 16 and the second strip section 17 of the double-layered section 14 to the position of the sewn section 12.

[0040] Since the first adhesive layer 31 is provided, the double-layered section 14 (in particular the second strip section 17) of the carrier mounting edge 11 can be reliably attached to the zipper tape 22, thus preventing the double-layered section 14 from being lifted and moved away from the zipper tape 22. This prevents the zipper tape 22, concealed beneath the double-layered section 14, from being exposed on the outer surface of the product with the attached zipper 1 (garment) when the double-layered section 14 is lifted. In the present invention, the first adhesive layer can be provided in at least a portion of the area extending in the left and right directions between the zipper tape and the second strip section.

[0041] In embodiment 1, a second adhesive layer 32 is provided between the underside of the first strip section 15 and the top side of the second strip section 17 in the double-layered section 14 to bond the first strip section 15 and the second strip section 17 together. Because the second adhesive layer 32 is provided, the U-shape of the double-layered section 14 can be reliably maintained.

[0042] In the present invention, the materials and thicknesses of the first adhesive layer 31 and the second adhesive layer 32 are not particularly limited. Furthermore, in the present invention, the product with an attached zipper can be manufactured without the second adhesive layer being provided between the first strip section and the second strip section.

[0043] The zipper 20 of embodiment 1 comprises the pair of left and right zipper carriers 21, each comprising the zipper tape 22 and a row of elements 26 formed on a side edge of the zipper tape 22, as well as a slider 40 slidably attached to the left and right rows of elements 26. In embodiment 1, each of the left and right zipper carriers 21 is attached to the carrier attachment edge 11 of the corresponding left and right fabric pieces 10 by the sewn section 12 described above (see Fig. 1 and Fig. 2).

[0044] In embodiment 1, the slide 40 is essentially similar to the slide described in the aforementioned international publication No. 2011 / 064893 (PTL 1) or in international publication No. 2017 / 094145. The slide 40 of embodiment 1 is briefly described below. The slide 40 comprises a slide body 41 and a pull tab 45 attached to the slide body 41.The slide body 41 comprises an upper leaf 42; a lower leaf (not shown) arranged parallel to the upper leaf 42; a connecting pin (not shown) connecting the front ends of the upper leaf 42 and the lower leaf; a left and a right upper flange (not shown) extending from the left and right side edges of the upper leaf 42 towards the lower leaf; a left and a right lower flange (not shown) extending from the left and right side edges of the lower leaf towards the upper leaf 42; and a pull tab attachment section 43 to which the pull tab 45 is attached and which is formed integrally with a top surface of the upper leaf 42.

[0045] The slide body 41 has a left and a right shoulder opening on both sides of the connecting pin at its front end. The slide body 41 also has a rear opening at its rear end. A substantially Y-shaped element guide track is provided between the upper leaf 42 and the lower leaf of the slide body 41, which communicates with the left and right shoulder openings and the rear opening. The upper and lower flanges of the slide body 41 have insertion slots between them for receiving first wing sections 24b and second wing sections 25b of the zipper elements 23 described below. The insertion slots communicate with the element guide track.

[0046] Each of the left and right zipper carriers 21 comprises the long and narrow zipper tape 22 and the zipper elements 23 made of a synthetic resin, which are provided on a side edge of the zipper tape 22. The zipper elements 23 are provided on the side edge of the zipper tape 22 that faces the zipper carrier 21, with which the zipper elements 23 are to engage.

[0047] Each zipper tape 22 comprises a tape body 22a with a front and a back, and a core strand 22b, which is provided on an inner side of the tape body 22a. The core strand 22b is formed integrally with the side edge of the tape body 22a and extends longitudinally along the tape. The core strand 22b protrudes from the tape body 22a in the upper and lower direction.

[0048] The zipper tape 22 of embodiment 1 does not include a waterproof layer to prevent or reduce the ingress of water and is not waterproof. In the present invention, the structure and properties of the zipper tape and the method for manufacturing the zipper tape 22 are not particularly limited, and at least a portion of the zipper tape 22 can be waterproof.

[0049] The zipper elements 23, made of a synthetic resin, are arranged at equal intervals along the side edge of the zipper tape 22 in the front and back directions, forming the element row 26. Each zipper element 23 is formed by injection molding using the synthetic resin on the zipper tape 22. Each zipper element 23 is not connected to the zipper elements 23 adjacent to it in the front and back directions and has a separate, independent shape.

[0050] Each zipper element 23 comprises at least one element base 23a with a section of constant thickness and a wing section 23b extending outwards in the left and right directions from the element base 23a (i.e., towards the inner region of the zipper tape 22). The wing section 23b has a lesser thickness than the element base 23a. The thickness is a dimension in the top and bottom directions, and the thickness of the element base 23a is the dimension from the top surface to the bottom surface of the element base 23a in the top and bottom directions. The wing section 23b comprises the first wing section 24b in the lower region described below and the second wing section 25b in the upper region described below.

[0051] Since each zipper element 23 includes the wing section 23b, the slider 40 can slide along the row of elements 26, so that the upper and lower flanges of the slider 40 are received by gaps formed outside the steps between the element base 23a and the wing section 23b in the left and right directions. Thus, the slider 40 can slide without being easily caught by the support mounting edge 11 of the fabric piece 10, and therefore the sliding movement of the slider 40 can occur smoothly.

[0052] The shape of each zipper element 23 will now be described in more detail. Each zipper element 23 comprises a first element section 24, which is located on the back of the zipper tape 22, and a second element section 25, which is located on the front of the zipper tape 22 and has a different shape than the first element section 24. In this case, the first element section 24 of the zipper element 23 is concealed on the inside of the garment 1 with the attached zipper. The second element section 25 is exposed on the outside of the garment.

[0053] Although not shown in detail, the first element section 24 comprises a first body section directly attached to the zipper tape 22; a first wing section 24b extending outwards in the left and right directions from the first body section; a neck section extending inwards in the left and right directions from the first body section; and an engagement head section 24a extending further inwards in the left and right directions from the neck section, having a substantially elliptical shape in the top view of the zipper element 23.

[0054] The first body section, viewed from above, is essentially isosceles trapezoidal in shape, as seen from the zipper element 23 ( Fig. 3) The neck section has a narrowed shape to engage with the engagement head sections 24a of two zipper elements 23 to be brought into engagement with it. The first wing section 24b extends outwards in the left and right directions from the first body section and has a reduced thickness at a first step section 24c compared to the first body section. The thicknesses of the first body section and the first wing section 24b are dimensions from the back of the zipper tape 22 to the undersides of the first body section and the first wing section 24b in the top and bottom views.

[0055] As in Fig. As shown in Figure 2, the second element section 25 comprises a second body section 25a, which is directly attached to the zipper tape 22; a second wing section 25b, which extends outwards in the left and right directions from the second body section 25a; and an element head section 25c, which extends inwards in the left and right directions from the second body section 25a. The element head section 25c is shaped such that its dimension decreases in two steps towards the tip of the element head section 25c in the longitudinal direction of the tape.

[0056] The second wing section 25b extends outwards in the left-right direction from the second body section 25a, and its height from the zipper band 22 is reduced at a second step section 25d compared to that of the second body section 25a.

[0057] An end surface of the second wing section 25b, pointing outwards in the width direction, and the support mounting edge 11 of the fabric piece 10 are in contact with each other. The state in which the second wing section 25b of the zipper element 23 and the support mounting edge 11 of the fabric piece 10 are in contact with each other is maintained by the first adhesive layer 31, which is provided between the zipper tape 22 and the second strip section 17.

[0058] Thus, the first adhesive layer 31 maintains the condition in which the carrier-attachment edge 11 (double-layered section 14) of the fabric piece 10 is in contact with the second wing section 25b of each zipper element 23. Accordingly, the zipper tape 22 can be reliably covered and concealed by the carrier-attachment edge 11 of the fabric piece 10 over an area that excludes sections thereof (more precisely, sections of the zipper tape 22 that are located between the zipper elements 23 adjacent in the front and back directions). Therefore, it is possible to prevent the zipper tape 22 from being exposed in an area between the zipper receiving element 10 and the zipper elements 23 in the left and right directions.

[0059] In each zipper element 23 of embodiment 1, the first wing section 24b and the second wing section 25b have shapes that are symmetrical to each other in the upper and lower directions around the zipper tape 22. The wing section 23b, which comprises the first wing section 24b and the second wing section 25b, has a thickness dimensioned such that the wing section 23b can be inserted into the corresponding insertion slot in the slider 40. The first step section 24c and the second step section 25d of the zipper elements 23 are slidable along the upper and lower flanges of the slider 40.

[0060] Since each zipper element 23 comprises the first wing section 24b and the second wing section 25b as described above, and although the carrier fastening edge 11 of each fabric piece 10 is held in contact with the second wing sections 25b of the zipper elements 23 as described above, the slider 40 can slide along the left and right element rows 26, while the upper and lower flanges of the slider 40 are prevented or prevented from coming into contact with the left and right fabric pieces 10. Therefore, the sliding movement of the slider 40 can occur smoothly regardless of the thickness of the fabric piece 10.

[0061] In the present invention, each zipper element can be designed such that the first and second wing sections are omitted. In such a case, the zipper elements preferably have recessed insertion grooves for receiving the upper and / or lower flanges of the slider. Even with such insertion grooves, the sliding movement of the slider can be smooth.

[0062] Since each zipper element 23 comprises the first element section 24 and the second element section 25 as described above, water does not easily penetrate from top to bottom through the left and right element rows 26 when the left and right element rows 26 are engaged with each other. If, for example, each zipper element 23 is water-repellent, the possibility of water penetration can be further reduced. In the present invention, the shape of the zipper elements is not particularly restricted, as long as the zipper elements are shaped such that the left and right element rows can engage with each other.

[0063] Next, a method for manufacturing the garment 1 with a zipper is described, in which the zipper straps 21 of the zipper 20 are attached to the strap attachment edges 11 of the fabric pieces 10.

[0064] In the following description of the sewing machine and the sewing process, a front and back direction refers to the feed direction of the sewing machine, i.e., the direction along which each zipper pull 21 and each piece of fabric 10, which are the sewing objects, are fed. The direction in which the sewing objects are fed is called forward, and the opposite direction is called reverse. An up and down direction is the direction in which the sewing machine needle moves back and forth. The direction in which the sewing needle penetrates the sewing objects is called down, and the direction in which the sewing needle is withdrawn from the sewing objects is called up. A left and right direction is a direction that is perpendicular to the direction in which the sewing objects are fed and to the direction in which the sewing needle moves back and forth.

[0065] First, as in Fig. Figure 5 shows a sewing step (sewing process) being carried out to sew together the zipper tape 22 of the zipper carrier 21 and the carrier attachment edge 11 of the fabric piece 10 using the sewing machine. In the Fig. 5 and Fig. 6 are the zipper carrier 21 and the carrier attachment edge 11 in reverse.

[0066] The sewing machine used in the sewing step of embodiment 1 is a sewing machine suitable for sewing the zipper carrier 21 and the carrier attachment edge 11 together with a straight stitch. The present invention does not impose any particular restriction regarding the sewing machine used in the sewing step.

[0067] In the sewing step, the zipper pull 21 and the support attachment edge 11 of the fabric piece 10 are first placed in a predetermined positional relationship on a needle plate (not shown) of the sewing machine, and then a presser foot (not shown) is lowered so that the zipper pull 21 and the support attachment edge 11 are held between the presser foot and the needle plate. The support attachment edge 11 of the fabric piece 10 is held in a flat position, and the U-shaped double-layered section 14 of the support attachment edge 11 is not yet formed. In this sewing step, the positional relationship between the zipper pull 21 and the support attachment edge 11 is not particularly restricted in the top and bottom directions.

[0068] After the zipper tape 21 and the tape attachment edge 11 are held in the predetermined positional relationship, the zipper tape 21 and the tape attachment edge 11 of the fabric piece 10 are intermittently transported using a feed mechanism of the sewing machine, and the sewing needle is moved back and forth in the up and down direction in accordance with the intermittent feed. In this way, the sewing needle sews the zipper tape 22 and the tape attachment edge 11 together with a running stitch. The running stitch forms the straight sewn section 12, consisting of threads (top and bottom threads) of the sewing machine and running in the forward and reverse directions, and the zipper tape 22 and the tape attachment edge 11 are sewn together with the sewn section 12.

[0069] The straight sewn section 12, consisting of the sewing machine threads, is formed at a position located to the left and right of the zipper elements 23. Therefore, unlike in the case where the sewn section is formed in contact with the zipper elements, no special feed mechanism is required to feed the zipper elements, allowing the sewing process to be easily performed with the sewing machine. Furthermore, the costs required for the sewing step can be reduced. The sewn section 12 formed during the sewing process is located to the left and right of the curved section 16 of the double-layered section 14 when the carrier fastening edge 11 is bent in a subsequent step to form the double-layered section 14.

[0070] Following the sewing step described above, a bending step is performed to bend the carrier attachment edge 11 of the fabric piece 10 to form the double-layered section 14.

[0071] In the bending step, the carrier-attachment edge 11 of the fabric piece 10 is bent so that the first strip section 15 and the second strip section 17 of the carrier-attachment edge 11 lie on top of each other in the upper and lower directions. The carrier-attachment edge 11 is bent so that the bent section 16 of the double-layered section 14 comes into contact with the zipper elements 23 (in particular the wing sections 23b). Thus, the fabric piece 10, including the carrier-attachment edge 11 to which the zipper carrier 21 is sewn, and including the in Fig. The double-layered section 14 shown in section 6 was produced.

[0072] After the bending step, part of the sewn section 12 is positioned between the first strip section 15 and the second strip section 17 of the double-layered section 14 and is thus surrounded by the double-layered section 14. Furthermore, the first strip section 15 of the double-layered section 14 is positioned above the sewn section 12, so that it covers the sewn section 12. Therefore, the sewn section 12 is concealed beneath the first strip section 15 and is not visible from above (from outside) the carrier fastening edge 11.

[0073] Next, a joining step is carried out. In this step, the first adhesive layer 31 and the second adhesive layer 32 are formed by applying adhesives 31a and 32a to the piece of fabric 10, which comprises the double-layered section 14 formed in the bending step and to which the zipper carrier 21 is attached.

[0074] In the connection step, as in Fig. As shown in Figure 6, the adhesive 31a is applied to the top surface of the zipper tape 22 and / or the underside of the second strip section 17 to form the first adhesive layer 31 described above. The first adhesive layer 31 fixes the zipper tape 22 and the second strip section 17 together. The adhesives 31a and 32a can, for example, be a hot melt adhesive or a reactive curing adhesive.

[0075] The adhesive 32a is applied to the top surface of the second strip section 17 and / or the bottom surface of the first strip section 15 in the double-layered section 14 to form the second adhesive layer 32 described above. The second adhesive layer 32 fixes the second strip section 17 and the first strip section 15 to one another. The order in which the first adhesive layer 31 and the second adhesive layer 32 are formed is not particularly restricted. In the present invention, the process for forming the second adhesive layer 32 can be omitted.

[0076] The fabric piece 10 with the zipper strap 21, which is sewn to its strap attachment edge 11, as shown in the Fig. The section 12, shown in Figures 2 to 4, is produced by performing the sewing, bending, and joining steps described above. The sewn section 12, formed by sewing together the zipper carrier 21 and the carrier attachment edge 11, is covered and concealed by the first strip section 15 of the carrier attachment edge 11. Therefore, the sewn section 12 is not visible from the outside of the fabric piece 10.

[0077] In embodiment 1, the sewing step, the bending step, and the joining step are performed in the sequence described above. However, in the present invention, the sequence in which the sewing step, the bending step, and the joining step are performed is not particularly restricted. For example, the bending step and the joining step can be performed before the sewing step.

[0078] Next, a pair of fabric pieces 10, to which the respective zipper pulls 21 are attached, are brought together, and the slider 40 is attached to the element rows 26 of the pair of zipper pulls 21 to create the fabric pieces 10 to which the zipper is attached. The garment 1 with the attached zipper is made by forming a garment from the fabric pieces 10 to which the zippers are attached.

[0079] In embodiment 1, the garment with zipper can also be manufactured by, for example, forming a garment using two pieces of fabric 10 to which the corresponding zipper carriers 21 are attached, and then attaching the slider 40 to the two rows of elements 26 provided on the garment.

[0080] In the garment with attached zipper of embodiment 1, manufactured as described above, the sewn section 12, which is formed by sewing together each zipper carrier 21 and the corresponding carrier attachment edge 11, is arranged in the left and right direction away from the zipper elements 23, and the zipper tape 22 and the double-layered section 14 (in particular the second strip section 17) are connected to each other by the first adhesive layer 31.

[0081] Therefore, the first adhesive layer 31 according to the garment with zipper 1 of embodiment 1 prevents the double-layered section 14 from lifting off the zipper carrier 21, and the condition in which the double-layered section 14 is in contact with (or near) the zipper elements 23 can be reliably maintained. This prevents the zipper tape 22 from being exposed to the outside in the area between the zipper receiving element 10 and the zipper elements 23.

[0082] As described above, in the garment 1 with attached zipper according to embodiment 1, essentially the entire zipper of the zipper tape 22 is covered and concealed from the outside (top) by the support attachment edge 11 of the fabric piece 10, so that the area in which the zipper tape 22 is exposed can be reduced. Accordingly, adverse effects on, for example, the design and appearance of the garment due to the exposure of the zipper tape 22 can be eliminated or reduced, so that a garment with good design or high appearance quality can easily be produced.

[0083] Additionally, in embodiment 1, as described above, the area in which the zipper tape 22 is exposed can be reduced. Furthermore, part of the double-layered section 14 (tab) forms a waterproof area between the sewn section 12 and the zipper elements 23. Therefore, even if, for example, the zipper tape 22 itself is not waterproof, at least if the fabric piece 10 of the garment is waterproof, liquid, such as water, will not easily penetrate from the outside through the zipper 20 provided on the garment to the inside. Since the zipper tape 22 is not waterproof in this case, manufacturing costs can also be reduced and the manufacturing process simplified. Design 2

[0084] Fig. Figure 7 is a schematic sectional view of a part of a product with an attached zipper according to embodiment 2, along a plane orthogonal to the front and back directions.

[0085] Similar to embodiment 1 described above, a product with an attached zipper 2 of embodiment 2 is a garment. The garment with an attached zipper 2 of embodiment 2 comprises a zipper 20 and one or more zipper receiving elements (fabric pieces) 50. The zipper 20 comprises a pair of left and right zipper pulls 21. The zipper receiving elements (fabric pieces) 50 comprise left and right pull attachment edges 51 to which the left and right zipper pulls 21 are attached.

[0086] The garment 2 with zipper of embodiment 2 has the following two differences from the garment 1 with zipper of embodiment 1 described above. The first difference is that the garment 2 with zipper of embodiment 2 does not include the first adhesive layer 31 and the second adhesive layer 32 described above in embodiment 1. The second difference is that in the garment 2 with zipper of embodiment 2, each fabric piece 50 has a double-layered section 54 (in particular, a curved section 56) which has properties that allow it to retain a curved shape by subjecting the fabric piece 50 to heat treatment (for example, a heat-setting process).

[0087] The garment with attached zipper 2 of embodiment 2 is essentially similar to the garment with attached zipper 1 according to embodiment 1, with the exception of the two differences described above. For example, the zipper pulls 21 used in embodiment 2 are essentially similar to the zipper pulls 21 according to embodiment 1.

[0088] Therefore, in the description of embodiment 2 and in the description of embodiments 3 and 4 provided below, components, elements, etc., which are essentially similar to those of the garment with zipper 1 of embodiment 1, are designated with the same reference numerals as in embodiment 1, and their detailed description is therefore omitted.

[0089] The left and right fabric pieces 50, which are included in the garment 2 of embodiment 2, are at least waterproof. Each of the left and right fabric pieces 50 comprises a fabric body (not shown) and a support fastening edge 51 provided at one edge of the fabric body. The support fastening edge 51 of each fabric piece 50 comprises the double-layered section 54, which is U-shaped and in which sections of the fabric piece 50 of the garment overlap in the upper and lower directions.

[0090] In a sectional view along a plane orthogonal to the front and back directions, the double-layered section 54 of embodiment 2 comprises a first strip section 55 extending inwards along the width direction from the fabric body (not shown), a curved section 56 extending from the first strip section 55, and a second strip section 57 extending from the curved section 56 and overlapping the first strip section 55. The zipper carrier 21 is attached to the second strip section 57 of the double-layered section 54 by the sewn section 12. The double-layered section 54 is configured in a state in which it is in contact with the wing section 23b (second wing section 25b) of each zipper element 23.

[0091] The double-layered section 54 of embodiment 2 is subjected to heat treatment, for example a heat-setting process, while being bent into a U-shape or a U-like shape, such that the double-layered section 54 has properties that maintain the bent shape on the bent section 56. In other words, the double-layered section 54 of embodiment 2 has properties such that, for example, if the U-shaped double-layered section 54 is subjected to an external force and deforms in one direction to separate the first strip section 55 and the second strip section 57 from each other, the double-layered section 54 returns to its original shape after the external force is removed.In embodiment 2, the “original shape” to be restored comprises a shape that is identical to the shape before deformation and a shape that closely approximates (is essentially identical to) the shape before deformation. The heat treatment comprises a process in which the treated object is heated.

[0092] Since the double-layered section 54 of embodiment 2 has the properties described above, it easily retains its U-shape when no external force is applied. Therefore, the zipper tape 22 is not easily exposed in the area between the zipper receiving element 50 and the zipper elements 23. When the double-layered section 54 is subjected to an external force, part of the second strip section 57 can be temporarily displaced from the zipper tape 22, or the double-layered section 54 can be lifted and displaced from the zipper tape 22. Even in such a case, after the external force is removed, the double-layered section 54 can return to its original U-shape, so that the zipper tape 22 is again covered by the double-layered section 54 and is not easily exposed.

[0093] In embodiment 2, the curved section 56 of the double-layered section 54 can have a fold line formed by applying heat and pressure, for example, in an ironing process. If the curved section 56 has such a fold line, the curved shape of the double-layered section 54 (in other words, the U-shape of the double-layered section 54) can be further stabilized. In embodiment 2, an element, for example, a film, can be placed within the double-layered section 54 to facilitate maintaining its shape. In this case as well, the curved shape of the double-layered section 54 can be further stabilized.

[0094] In embodiment 2, the support attachment edge 51 and the zipper support 21 are sewn together in a lockstitch operation using a sewing machine to form the sewn section 12. The sewn section 12 extends straight in the front and back directions of the zipper tape 22. The sewn section 12 fixes the zipper support 21 to the support attachment edge 51 of the fabric piece 50. Part of the sewn section 12 is arranged between the first strip section 55 and the second strip section 57 of the double-layered section 54.

[0095] The sewn section 12 of embodiment 2 is separated from the zipper elements 23 in the left and right directions (towards the inner area of ​​the tape) and also separated from the curved section 56 of the carrier mounting edge 51 in the left and right directions. In this case, the separation distance D1 between the sewn section 12 and the wing section 23b of each zipper element 23 in the left-right direction is preferably 1.0 mm or more and 10.0 mm or less. The curved section 56 of the carrier mounting edge 51 is arranged in contact with the zipper elements 23, and a portion of the double-layered section 54 between the sewn section 12 and the curved section 56 in the left and right directions serves as a flap over the zipper tape 22. In this way, a watertight area is formed between the sewn section 12 and the zipper elements 23.

[0096] The following briefly describes a method for manufacturing the product with attached zipper 2 from embodiment 2.

[0097] First, a sewing step is performed to sew together the zipper tape 22 of the zipper carrier 21 and the carrier attachment edge 51 of the fabric piece 50 using a sewing machine. After the sewing step, a bending step is performed in which the carrier attachment edge 51 of the fabric piece 50 is bent to form the double-layered section 54. The sewing and bending steps of embodiment 2 are performed essentially similarly to the sewing and bending steps of embodiment 1 described above.

[0098] A heat treatment step is then carried out. In this step, the zipper carrier 21 and the carrier mounting edge 51, which has the double-layered section 54 formed in the bending step, are subjected to heat treatment to stabilize the shape of the zipper carrier 21.

[0099] In the heat treatment step of embodiment 2, a heat treatment (heat fixing process) is carried out to heat the double-layered section 54 of the support mounting edge 51 while the double-layered section 54 is bent into a U-shape. In this way, the bent shape of the double-layered section 54 can be stabilized. For example, if the double-layered section 54 is deformed by an external force and the external force is then removed, the double-layered section 54 can return to its original shape before the deformation.

[0100] In the heat treatment step of embodiment 2, the heat treatment can, for example, be an ironing process in which the U-shaped, double-layered section 54 of the carrier mounting edge 51 is pressed and heated using an iron. The fold line described above can be easily formed on the curved section 56 of the double-layered section 54 by the ironing process.

[0101] In embodiment 2, the heat treatment step described above, which includes the heat-setting process or the ironing process, is carried out such that the double-layered section 54, which has the properties for retaining the curved shape of the bent section 56, can be reliably formed on the carrier attachment edge 51 of the fabric piece 50. In the present invention, the heat treatment step that enables the retention of the curved shape is not limited to the heat-setting process and the ironing process described above, and the heat treatment step may include other treatments and processes that involve heating.

[0102] The fabric piece 50 with the zipper carrier 21, which is sewn to its carrier attachment edge 51, as in Fig. Figure 7 is produced by performing the sewing step, the bending process, and the heat treatment step described above. The sewn section 12, formed by sewing together the zipper carrier 21 and the carrier attachment edge 51, is covered and concealed by the carrier attachment edge 51 (in particular by the first strip section 55).

[0103] In embodiment 2, the sewing step, the bending step, and the heat treatment step are performed in the sequence described above. However, in the present invention, the sequence in which the sewing step, the bending step, and the heat treatment step are performed is not particularly restricted. For example, the bending step and the heat treatment step can be performed before the sewing step.

[0104] Then, similar to embodiment 1 described above, the garment 2 with attached zipper can be produced by using the fabric pieces 50 of embodiment 2 to which the respective zipper carriers 21 are sewn.

[0105] In the garment 2 with zipper manufactured as described above according to embodiment 2, the sewn section 12 is arranged away from the zipper elements 23 in the left and right directions. However, since the double-layered section 54 of the carrier fastening edge 51 is subjected to heat treatment (heat treatment step) to stabilize its shape, the curved shape of the curved section 56 can be retained.

[0106] Therefore, according to the garment with attached zipper of embodiment 2, the double-layered section 54 of the carrier attachment edge 51 is not easily lifted from the zipper carrier 21, and the condition in which the double-layered section 54 is in contact with (or near) the zipper elements 23 can be easily maintained.

[0107] Thus, in embodiment 2, the exposure of the zipper tape 22 to the outside in the area between the zipper receiving element 50 and the zipper elements 23 can be prevented or reduced, so that essentially the entire zipper tape 22 can be easily covered and concealed by the carrier fastening edge 51. Therefore, adverse effects on, for example, the design and appearance of the garment due to the exposure of the zipper tape 22 can be avoided or reduced.

[0108] In the garment with zipper of embodiment 2, similar to embodiment 1 described above, even if the zipper tape 22 itself is not waterproof, no liquid easily penetrates through the zipper 20 if at least the fabric piece 50 of the garment is waterproof. embodiment 3

[0109] Fig. Figure 8 is a schematic sectional view of a part of a product with an attached zipper according to embodiment 3, taken along a plane orthogonal to the front and back directions.

[0110] Similar to embodiment 1 described above, a product with an attached zipper 3 of embodiment 3 is a garment. The garment with an attached zipper 3 of embodiment 3 comprises a zipper 20 and one or more zipper receiving elements (fabric pieces) 70. The zipper 20 comprises a pair of left and right zipper pulls 21. The zipper receiving elements (fabric pieces) 70 comprise a left and a right pull attachment edge 71 to which the left and right zipper pulls 21 are attached.

[0111] The garment 3 with zipper of embodiment 3 has the following three differences from the garment 1 with zipper of embodiment 1 described above. The first difference is that the garment 3 with zipper of embodiment 3 does not include the first adhesive layer 31 and the second adhesive layer 32 described above in embodiment 1. The second difference is that in the garment 3 with zipper of embodiment 3, the area of ​​the distance between the sewn section 12 and the wing section 23b of each zipper element 23 in the left and right directions differs from that in embodiment 1. The third difference is that the garment 3 with zipper of embodiment 3 includes a double-layered section 74 with a thickness T in a predetermined area.The garment 3 with zipper of embodiment 3 is essentially similar to the garment 1 with zipper of embodiment 1, with the exception of the three differences described above.

[0112] The left and right fabric pieces 70 of the garment used in embodiment 3 are at least waterproof. Each of the left and right fabric pieces 70 comprises a fabric body (not shown) and a support fastening edge 71 provided at one edge of the fabric body. The support fastening edge 71 of each fabric piece 70 comprises the double-layered section 74, which is U-shaped and in which sections of the fabric piece 70 of the garment overlap in the upper and lower directions.

[0113] In a section along a plane perpendicular to the front and back directions, the double-layered section 74 of embodiment 3 comprises a first strip section 75 extending inwards along the width direction from the fabric body (not shown), a curved section 76 extending from the first strip section 75, and a second strip section 77 extending from the curved section 76 and overlapping the first strip section 75. The zipper carrier 21 is attached to the second strip section 77 of the double-layered section 74 by the sewn section 12. The double-layered section 74 is configured in a state in which it is in contact with the wing section 23b (second wing section 25b) of the zipper element 23.

[0114] In embodiment 3, the thickness T of the double-layered section 74 of the support mounting edge 71 is 0.25 mm or more and 5.0 mm or less. The thickness T of the double-layered section 74 is the dimension from the top (outer surface) of the first strip section 75 to the bottom (outer surface) of the second strip section 77 in the top and bottom view.

[0115] If the thickness T of the double-layered section 74 is 0.25 mm or more, preferably 0.55 mm or more, the double-layered section 74 can easily be formed in a position close to the zipper elements 23. Therefore, the condition in which the double-layered section 74 is in contact with each zipper element 23 (in particular the wing section 23b) can be easily maintained. Accordingly, exposure of the zipper tape 22 in the area between the double-layered section 74 and the zipper elements 23 can be prevented or reduced.Even if the double-layered section 74 is subjected to an external force and is located slightly away from the zipper elements 23, the area between the double-layered section 74 and the zipper elements 23 can be easily concealed behind the double-layered section 74 because, as described above, the double-layered section 74 is thick in both the upper and lower directions. Therefore, the zipper tape 22 is not easily visible through the gap between the double-layered section 74 and the zipper elements 23.

[0116] If the thickness T of the double-layered section 74 is 5.0 mm or less, preferably 3.0 mm or less, the height of the step between the carrier attachment edge 71 and each zipper element 23 can be reduced, and a reduction in water resistance due to water droplets adhering to and remaining on this step can be prevented.

[0117] The thickness T of the double-layered section 74 can correspond to the thickness of the wing section 23b of each zipper element 23. In Fig. 8. The wing section 23b is tapered such that its thickness gradually decreases along the left and right directions (towards the inner area of ​​the band) from the zipper element 23 outwards. However, in order to eliminate or reduce the step between the wing section 23b and the double-layered section 74, the wing section 23b can be untapered or tapered over a smaller area.

[0118] In embodiment 3, the carrier attachment edge 71 and the zipper carrier 21 are sewn together using a lockstitch sewing process with a sewing machine to form the sewn section 12. The sewn section 12 extends straight in the front and back directions of the zipper tape 22. The sewn section 12 fixes the zipper carrier 21 to the carrier attachment edge 71 (second strip section 77) of the fabric piece 70. Part of the sewn section 12 is positioned between the first strip section 75 and the second strip section 77 of the double-layered section 74.

[0119] The sewn section 12 of embodiment 3 is separated from the zipper elements 23 to the outside in the left and right directions (towards the inner area of ​​the tape) and also to the outside in the left and right directions from the curved section 76 of the carrier mounting edge 71. In this case, the distance D2 between the sewn section 12 and the wing section 23b of each zipper element 23 is preferably 0.5 mm or more and 10.0 mm or less in the left and right directions. The curved section 76 of the carrier mounting edge 71 is arranged in contact with the zipper elements 23, and a portion of the double-layered section 74 between the sewn section 12 and the curved section 76 in the left and right directions serves as a flap over the zipper tape 22. In this way, a watertight area is formed between the sewn section 12 and the zipper elements 23.

[0120] If the separation distance D2 described above is 0.5 mm or more, preferably 0.8 mm or more, the sewing needle does not easily come into contact with the zipper elements 23 during the formation of the sewn section 12 using the sewing machine. Thus, the zipper tape 22 can be sewn smoothly and reliably to the carrier attachment edge 71 of the fabric piece 70 during the sewing process.

[0121] If the separation distance D2 described above is 10.0 mm or less, preferably 5.0 mm or less, the double-layered section 74 cannot be easily lifted. Therefore, the zipper tape 22 is not easily visible through the gap between the double-layered section 74 and the zipper elements 23. If the separation distance D2 described above is 10.0 mm or less, the zipper tape 22 and the second strip section 77 can be prevented from having excessively large widths, thus easily reducing manufacturing costs. If the separation distance is greater than 10.0 mm, it can be difficult to form the curved section 76 in a position where it is in contact with the zipper elements 23.

[0122] In the garment 3 described above, with an attached zipper according to embodiment 3, the sewn section 12 is positioned to the left and right of the zipper elements 23. However, since the thickness T of the double-layered section 74 is 0.25 mm or more, and the separation distance D2 between the sewn section 12 and the zipper elements 23 is only 10.0 mm or less, the double-layered section 74 of the carrier attachment edge 71 is not easily lifted from the zipper carrier 21, and the zipper tape 22 is not easily visible through the gap between the double-layered section 74 and the zipper elements 23. Accordingly, adverse effects on, for example, the design and visual quality of the garment due to the exposure of the zipper tape 22 can be eliminated or reduced.

[0123] In the garment 3 with attached zipper device of embodiment 3, similar to embodiment 1 described above, even if the zipper tape 22 itself is not waterproof, no liquid easily penetrates through the zipper 20 if at least the fabric piece 70 of the garment is waterproof.

[0124] The garment with a zipper according to embodiment 3 can be designed such that it either meets the condition that the thickness T of the double-layered section 74 is 0.25 mm or more, or the condition that the distance D2 between the sewn section 12 and the wing section 23b of each zipper element 23 in the left-right direction is 10.0 mm or less. Even if the garment with the attached zipper meets one of the conditions described above, the zipper tape is not easily visible from the outside of the garment with the attached zipper. Design 4

[0125] Fig. Figure 9 is a schematic sectional view of a part of a product with a zipper according to embodiment 4 along a plane orthogonal to the front and back directions.

[0126] Similar to embodiment 1 described above, a product with an attached zipper device 4 of embodiment 4 is a garment. The garment with the attached zipper device 4 of embodiment 4 comprises a zipper 20 and one or more zipper receiving elements (fabric pieces) 90. The zipper 20 comprises a pair of left and right zipper strands 21. The zipper receiving elements (fabric pieces) 90 comprise a left and a right support attachment edge 91 to which the left and right zipper strands 21 are attached.

[0127] The garment with zipper 4 of embodiment 4 has the following three differences from the garment with zipper 1 of embodiment 1 described above. The first difference is that the garment with zipper 4 of embodiment 4 does not include the first adhesive layer 31 and the second adhesive layer 32 described above in embodiment 1. The second difference is that a curved section 96 is located near the position where the sewn section 12 is formed and also near the zipper elements 23 in the left and right directions. The third difference is that in the garment with zipper 4 of embodiment 4, the area of ​​the distance between the sewn section 12 and the wing section 23b of each zipper element 23 in the left-right direction differs from that in embodiment 1.The garment 4 with zipper of embodiment 4 is essentially similar to the garment 1 with zipper according to embodiment 1, with the exception of the three differences described above.

[0128] The left and right fabric pieces 90 of the garment used in embodiment 4 are at least waterproof. Each of the left and right fabric pieces 90 comprises a fabric body (not shown) and a support fastening edge 91 provided at one edge of the fabric body. The support fastening edge 91 of each fabric piece 90 comprises the double-layered section 94, which is U-shaped and in which sections of the fabric piece 90 of the garment overlap in the upper and lower directions.

[0129] In a sectional view along a plane perpendicular to the front and back directions, the double-layered section 94 of embodiment 4 comprises a first strip section 95 extending inward along the width direction from the fabric body (not shown), a curved section 96 extending from the first strip section 95, and a second strip section 97 extending from the curved section 96 and overlapping the first strip section 95. The zipper carrier 21 is attached to the second strip section 97 of the double-layered section 94 by the sewn section 12. The double-layered section 94 is located near the wing section 23b (second wing section 25b) of each zipper element 23.

[0130] In embodiment 4, the support attachment edge 91 and the zipper support 21 are sewn together in a lockstitch operation using a sewing machine to form the sewn section 12. The sewn section 12 extends straight in the front and back directions of the zipper tape 22. The sewn section 12 fixes the zipper support 21 to the support attachment edge 91 (second strip section 97) of the fabric piece 90. Part of the sewn section 12 is arranged between the first strip section 95 and the second strip section 97 of the double-layered section 94.

[0131] The sewn section 12 of embodiment 4 is separated from the zipper elements 23 in the left and right directions (towards the inner area of ​​the band). The carrier fastening edge 91 is bent at the sewn section 12 such that the first strip section 95 and the second strip section 97 overlap in the upward and downward directions to form the double-layered section 94. Therefore, the bent section 96 is formed in a position close to the sewn section 12.

[0132] In this case, the separation distance D3 between the sewn section 12 and the wing section 23b of each zipper element 23 in the left-right direction is preferably 3.0 mm or less. Preferably, the distance D3 is 2.0 mm or less, or 1.0 mm or less. The distance D3 is preferably 0.5 mm or more. In other words, the distance D3 is preferably 60% or less of the width of each zipper element 23 (here, the width excluding the width of the first and second wing sections) in the left-right direction. Preferably, the distance D3 is 40% or less, or 20% or less of the width of each zipper element 23 excluding the wing sections in the left-right direction. The distance D3 is preferably 10% or more of the width of each zipper element 23 excluding the wing sections in the left-right direction.In embodiment 4, unlike embodiments 1 to 3, no flap is formed in the area between the position of the sewn section 12 and the position of the curved section 96. However, since the separation distance D3 is small, a waterproof area is provided between the sewn section 12 and the zipper elements 23.

[0133] If the separation distance D3 described above is 0.5 mm or more, or 10% or more of the width of each zipper element 23 excluding the flap sections in the left and right directions, the sewing needle does not easily come into contact with the zipper elements 23 during the formation of the sewn section 12 using the sewing machine. Thus, the zipper tape 22 can be sewn smoothly and reliably to the carrier attachment edge 91 of the fabric piece 90 during the sewing process.

[0134] If the separation distance D3 described above is 3.0 mm or less or 60% or less of the width of each zipper element 23 excluding the wing sections in the left-right direction, the zipper tape 22 is not easily visible through the gap between the double-layered section 94 and the zipper elements 23.

[0135] In the garment 4 described above, with an attached zipper according to embodiment 4, the sewn section 12 is positioned away from the zipper elements 23 in both the left and right directions. However, since the distance D3 between the sewn section 12 and the zipper elements 23 is only 3.0 mm or less, the zipper tape 22 is not easily visible through the gap between the double-layered section 94 and the zipper elements 23. Accordingly, adverse effects on, for example, the design and appearance of the garment due to the exposure of the zipper tape 22 can be avoided or reduced.

[0136] In the garment 4 with zipper of embodiment 4, similar to embodiment 1 described above, even if the zipper tape 22 itself is not waterproof, no liquid easily penetrates through the zipper 20 due to the waterproof area described above, provided that at least the fabric part 90 of the garment is waterproof.

[0137] For each of embodiments 1 to 4, a rain test as described below was performed to confirm that a waterproof zone was formed between the sewn section 12 and the zipper elements 23. The rain test was conducted under rain conditions according to AATCC35 (24 inches, 2 minutes). To eliminate the influence of water leaking through gaps between the zipper elements 23, a leak-proof tape was applied to the front faces of the zipper elements 23 during the test. As a result of the rain test, it was confirmed that the water permeability of the waterproof zone in embodiments 1 to 4 was less than 0.1 g in each case.

[0138] The present invention is not limited to the embodiments 1 to 4 described above, and various modifications are possible as long as an essentially identical configuration to that of the present invention is provided and similar effects are achieved.

[0139] For example, in embodiments 1 to 4, the zipper 20 and the zipper carriers 21 are formed by means of independently shaped zipper elements 23 being formed on the zipper tapes 22 by injection molding using a synthetic resin. However, in the present invention, the zipper and the zipper carriers can be formed by forming independently shaped zipper elements made of metal on the zipper tapes instead of the zipper elements 23 being made of a synthetic resin.

[0140] Although the garment with the attached zipper is at least waterproof in embodiments 1 to 4, it is not necessary for the garment with the attached zipper to be waterproof in the present invention. Although the garment in these embodiments is described as a typical example of a product to which the zipper is attached, the product with the attached zipper in the present invention is not limited to a garment. The product with the attached zipper device according to the present invention can comprise various products, including apparel products other than garments, everyday products such as shoes and bags, industrial materials, and various seating products for automobiles, trains, and aircraft.
