Description

Technical Field

[0001] The present invention relates to a product with a zipper and a method for manufacturing the product with a zipper. The product with a zipper comprises: a chain element component, which is formed by installing a plurality of zipper elements on a longitudinal fixed component; and a zipper installation component, which has a chain element installation edge for installing the chain element component. Background Art

[0002] Zippers are commonly used as opening and closing devices for products such as clothing, daily necessities, industrial equipment, and various types of seats in automobiles, trains, and aircraft. Zippers used in these various products typically comprise a pair of left and right zipper tapes, each with a row of fastener elements formed along the tape's side edges, and a slider that slides along the left and right rows of elements. Also known as zippers are zippers equipped with a detachable insert that allows the left and right zipper tapes to be separated.

[0003] In conventional zippers and zipper tapes, for example, injection-molded synthetic resin zipper elements are attached to the tape's side edges, forming a row of elements on these edges. Furthermore, when attaching a zipper to a zipper-attaching member such as clothing, the portion of the zipper tape excluding the tape's side edges (generally referred to as the tape body) is typically sewn together with a sewing machine, while the two are stacked. Therefore, in typical zippers, the zipper tape is typically used as an integral component (part) to form the zipper.

[0004] In contrast, for example, International Publication No. 2018 / 142548 (Patent Document 1) describes a product with a zipper that is configured as a zipper without using a zipper tape and has a detachable insert formed at a predetermined position.

[0005] For example Figure 8 As shown, the zipper product 70 described in Patent Document 1 is a garment, and fastener elements 71 are sewn to left and right fabrics 72 forming the garment. Each of the left and right fastener elements 71 includes a string-shaped fixing member 73 and a plurality of synthetic resin fastener elements 74 fixed to the fixing member 73.

[0006] Each zipper element 74 of the element member 71 is formed into a predetermined shape by injection molding of synthetic resin. Each zipper element 74 comprises a main body portion secured to the fixing member 73; a neck portion extending from the main body portion and having a constricted shape; an engaging head portion extending further from the neck portion; and a shoulder portion protruding from the neck portion in a thin plate-like shape. This element member 71 is directly secured to the fabric 72 using a fixing stitched portion 75 and an auxiliary stitched portion 76 formed by sewing with a sewing machine.

[0007] In the zippered product (garment) 70 in which the left and right fastener element members 71 of Patent Document 1 are directly sewn to the fabric 72, the fastener tape required in conventional general zippers is unnecessary, thereby making it possible to reduce the weight of the product and improve its flexibility.

[0010] Patent Document 1: International Publication No. 2018 / 142548 Summary of the Invention

[0011] Problems to be solved by the invention

[0012] In the case of the zipper product 70 described in Patent Document 1, the fixing stitched portion 75 and the auxiliary stitched portion 76 that fix the element member 71 to the fabric 72 are exposed on the surface (external surface) of the fabric 72 that is exposed to the outside. Therefore, the fixing stitched portion 75 and the auxiliary stitched portion 76 are arranged so as to be visible from the outside of the product 70. Therefore, depending on the type of zipper product 70, there is a possibility that the fixing stitched portion 75 and the auxiliary stitched portion 76 may affect the product's appearance quality.

[0013] The fixing stitched portion 75 and the auxiliary stitched portion 76 are formed by sewing a portion of the fabric 72 and the fastener element 71 together using a sewing machine while the portion of the fabric 72 is folded back into a U-shape. Therefore, the fixing stitched portion 75 and the auxiliary stitched portion 76 are formed so as to extend from the outer surface of the fabric 72 exposed to the outside to the back surface of the portion folded back into a U-shape at the needle drop position of the sewing machine during sewing.

[0014] However, in this case, when liquid such as water adheres to the outer surface of the fabric 72, there is a possibility that the liquid may easily penetrate the back surface of the fabric 72 through the portion that passes from the outer surface to the back surface of the fabric 72. Therefore, in the zipper product 70 of Patent Document 1, it is difficult to impart waterproofness to the portion of the fabric 72 to which the element member 71 is fixed so as to prevent water or the like from penetrating the back surface.

[0015] The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a product with a slide fastener in which a sewn portion for fixing an element member to an element attaching edge portion is less visible, and a method for manufacturing the product with a slide fastener.

[0016] Solutions for solving problems

[0017] In order to achieve the above-mentioned purpose, the zipper product provided by the present invention comprises: a chain element component, which is formed by installing zipper chain elements on a fixing component; and a zipper installation component, which has a chain element installation edge for installing the chain element component, and the chain element installation edge has a first surface and a second surface arranged on the opposite side of the first surface. The main feature of the zipper product is that the chain element component is fixed to the first surface of the chain element installation edge by a fixing sewing portion, and the fixing sewing portion has a first sewing line arranged on the first surface side of the chain element installation edge and a second sewing line arranged on the second surface side, and the first sewing line and the second sewing line intersect each other at a position where the fixing sewing portion passes through the chain element installation edge. The chain tooth mounting edge portion has a folded shape in which the second surface faces each other to form an inner circumferential surface, and when observing a cross section perpendicular to the length direction of the fixing member, it has: a main body side mounting edge portion, which extends from the folded center position to one side of the chain tooth mounting edge portion; and a folded side mounting edge portion, which extends from the folded center position to the other side of the chain tooth mounting edge portion, and the fixing sewing portion has: a main body side through portion, which penetrates the main body side mounting edge portion of the chain tooth mounting edge portion; a folded side through portion, which penetrates the folded side mounting edge portion of the chain tooth mounting edge portion; and a cross portion, in which the first sewing line spans the fixing member between the main body side through portion and the folded side through portion and presses the fixing member.

[0018] In the slide fastener product of the present invention, it is preferable that the number of the main body-side through-holes provided per one fastener element is smaller than the number of the fold-back-side through-holes provided per one fastener element.

[0019] In addition, it is preferable that the folded-back side attachment edge portion is welded or bonded to the main body side attachment edge portion.

[0020] Furthermore, it is preferable that the fixing sewn portion is formed by a flat stitch or a chain stitch.

[0021] Next, regarding the manufacturing method of the zipper product provided by the present invention, the zipper product comprises: a chain tooth component, which is formed by installing zipper chain teeth on a fixing component; and a zipper installation component, which has a chain tooth installation edge portion for installing the chain tooth component, and the chain tooth installation edge portion has a first surface and a second surface arranged on the opposite side of the first surface. The main feature of the manufacturing method of the product with a zipper is that the manufacturing method of the product with a zipper comprises: placing the chain tooth component on the first surface of the chain tooth installation edge portion in a posture in which the main body portion of the zipper chain tooth contacts the chain tooth installation edge portion and the meshing head of the zipper chain tooth is away from the chain tooth installation edge portion; using a sewing machine to sew the chain tooth installation edge portion on which the chain tooth component is placed, thereby forming a chain tooth installation edge portion having a main body portion arranged on the first surface side of the chain tooth installation edge portion. and a fixing sewing portion having a first sewing line and a second sewing line arranged on the second surface side, and the chain tooth component is fixed to the first surface of the chain tooth mounting edge portion by using the fixing sewing portion; in the sewing process, the fixing sewing portion is formed in a manner having the following parts: a main body side through-hole portion, which penetrates the main body side mounting edge portion of the chain tooth mounting edge portion; a folded-back side through-hole portion, which penetrates the folded-back side mounting edge portion of the chain tooth mounting edge portion; and a span portion, in which the first sewing line spans the fixing component between the main body side through-hole portion and the folded-back side through-hole portion and presses the fixing component; and the folded-back side mounting edge portion of the chain tooth mounting edge portion to which the chain tooth component is fixed is folded back relative to the main body side mounting edge portion so that the second surfaces face each other and the second surface forms an inner circumferential surface.

[0022] Preferably, the method for manufacturing a product with a slide fastener of the present invention includes forming the fixing sewn portion so that the number of the main body-side through-portions provided per the fastener element is smaller than the number of the fold-back-side through-portions provided per the fastener element.

[0023] Furthermore, it is preferable that the method for manufacturing a product with a slide fastener of the present invention includes welding or adhering the folded-back side attachment edge portion to the main body side attachment edge portion.

[0034] Below, with reference to the attached Figure 1 The preferred embodiment of the present invention will be described in detail. The present invention is not limited to the embodiment described below, and various modifications are possible as long as the embodiments have substantially the same structure and provide the same functions and effects as the present invention.

[0035] For example, in the following embodiments, the case where the product with a zipper is a piece of clothing with a zipper is described, but the product with a zipper of the present invention is not limited to clothing (clothing), and includes a variety of products such as daily necessities such as shoes and bags, industrial equipment, various seats for cars, trains, aircraft, etc.

[0036] Example 1

[0037] Figure 1 1 is a top view schematically showing the main parts of a product (clothing) with a zipper according to this embodiment. Figure 2 It is a bottom view schematically showing the back side of the product with a zipper in an enlarged manner. Figure 3It is schematically represented Figure 1 A cross-sectional view of a cross section of a product with a zipper is shown. Figure 4 1 is a top view showing a fastener element component. Figure 5 It is magnified Figure 4 A perspective view of a zipper element of the element assembly shown.

[0038] In addition, in the following description, the front-to-back direction refers to the length direction of the chain tooth component parallel to the sliding direction of the slider, especially, the direction in which the slider slides so as to engage the left and right chain tooth rows is set to the front, and the direction in which the slider slides so as to separate the left and right chain tooth rows is set to the rear.

[0039] The left-right direction refers to the width direction of the tooth member (or the direction in which the left and right fabrics are pulled apart from each other when the left and right tooth rows are engaged), for example, a direction perpendicular to the sliding direction of the slider and parallel to the outer surface of the fabric. The up-down direction refers to a direction perpendicular to the front-back direction and the left-right direction, for example, a thickness direction of the tooth member perpendicular to the outer surface (upper surface) and back surface (lower surface) of the fabric. In particular, in the following case, the direction of the pull tab on the side where the slider is arranged relative to the tooth member is set to the upper side, and the direction of the opposite side is set to the lower side. Moreover, in this case, the outer surface of the fabric refers to the side exposed to the outside when wearing clothes with a zipper, and the back surface of the fabric refers to the side facing the body.

[0040] The product 1 with a zipper in this embodiment is a garment (clothing) 1 with a zipper, and a front placket of the garment 1 is formed with a zipper. Figure 1 The slide fastener 5 is shown. In addition, left and right element attaching edges 7 for attaching left and right element members 10 are provided on left and right fabrics 6 forming the front body (particularly, the placket) of the garment 1 as the opening and closing portion.

[0041] In this case, the fabric 6 (also referred to as clothing fabric) constituting the placket portion of the garment 1 becomes a member for attaching a zipper to which the element member 10 is attached. Figure 1 As shown, the zipper 5 formed in this embodiment has: a pair of left and right zipper element tape portions, which have a chain element row 11 formed by directly fixing the chain element component 10 to the fabric 6 of the clothing 1; and a slider 30, which can engage and disengage the chain element rows 11 of the left and right zipper element tape portions.

[0042] In this embodiment, the thickness, shape, and flexibility of the fabric 6 serving as the member for attaching the zipper are not particularly limited, but the fabric 6 is preferably formed so that a sewing machine needle can penetrate it during sewing.

[0043] In the present embodiment, the element attachment edge 7 provided on the fabric 6 has a predetermined dimension in the width direction of the element member 10, extending from the opposing side edges of the fabric 6 constituting the left and right placket portions in the completed zippered garment 1 toward the inner side of the fabric 6, and is formed continuously along the longitudinal direction of the element member 10. In the present embodiment, the element attachment edge 7 is a portion that includes, in the width direction, at least the range from the opposing side edges to the top end of the folded-back attachment edge 9, which will be discussed later.

[0044] Each of the left and right element mounting edges 7 has a first surface 7a forming one surface of the fabric 6 and a second surface 7b disposed on the opposite side of the first surface 7a of the fabric 6 and forming the other surface of the fabric 6. Figure 3 As shown, each element attachment edge 7 has a portion in the width direction of the element attachment edge 7 folded back in a U-shape toward the lower surface with the second surface 7b of the element attachment edge 7 facing each other.

[0045] In this case, the second surface 7b of the element mounting edge portion 7 bent into a U-shape forms the inner peripheral surface of the element mounting edge portion 7, and the first surface 7a of the element mounting edge portion 7 forms the outer peripheral surface of the element mounting edge portion 7. In addition, in the element mounting edge portion 7 bent into a U-shape, when observing a cross section perpendicular to the front-back direction of the element mounting edge portion 7, when the center portion in the vertical direction of the element mounting edge portion 7 is defined as the folding center position 7c, the element mounting edge portion 7 includes: a main body side mounting edge portion 8 extending from the folding center position 7c to one side of the element mounting edge portion 7; and a folding side mounting edge portion 9 extending from the folding center position 7c to the other side of the element mounting edge portion 7.

[0046] The folding center position 7c can also be referred to as the position of the zipper element 12 closest to the element member 10 in the element attaching edge 7. Furthermore, the main body side attaching edge 8 of the element attaching edge 7 is a portion extending from the folding center position 7c toward the outer surface 6a of the element attaching edge 7 (the fabric 6) exposed to the outside. The folding side attaching edge 9 is a portion extending from the folding center position 7c toward the back surface (inner surface) 6b of the element attaching edge 7.

[0047] The fold-back side mounting edge 9 is fixed (fused) to the main body side mounting edge 8 by means of a welding tape 40. In this embodiment, the welding tape 40 is attached to the second surface 7b of the element mounting edge 7 over the entire range in the left-right direction from the fold-back center position 7c of the element mounting edge 7 to the top edge (cut edge) of the fold-back side mounting edge 9. Within this range, the second surface 7b of the main body side mounting edge 8 and the second surface 7b of the fold-back side mounting edge 9 are fixed by the welding tape 40. This further improves the strength of the element mounting edge 7.

[0048] Furthermore, even if the sewing machine needle pierces the element mounting edge 7 during sewing processing performed by a sewing machine as will be discussed later, thereby forming a through portion extending from the first surface 7a to the second surface 7b of the element mounting edge 7 and the element member 10, the second surface 7b side of the through portion can be sealed by the welding tape 40. This effectively prevents water, etc. from entering the second surface 7b from the first surface 7a of the element mounting edge 7 and water, etc. from entering the back surface 6b from the outer surface 6a of the element mounting edge 7, thereby imparting waterproofness to the sewn element mounting edge 7.

[0049] Furthermore, in the present invention, the element attachment edge 7 may be fixed by the welding tape 40, for example, only a portion of the second surface 7b of the main body-side attachment edge 8 and a portion of the second surface 7b of the fold-back-side attachment edge 9 within the aforementioned range in the left-right direction. Furthermore, the main body-side attachment edge 8 and the fold-back-side attachment edge 9 of the element attachment edge 7 may be welded together not by the welding tape 40 as in the present embodiment, but by other welding means such as ultrasonic welding, or by adhesive or the like. Furthermore, the main body-side attachment edge 8 and the fold-back-side attachment edge 9 may be sewn together, for example, with thread.

[0050] The left and right fastener element members 10 in this embodiment are sewn along the longitudinal direction to the left and right fastener element mounting edges 7 provided to the garment 1. Each of the left and right fastener element members 10 includes a plurality of independent fastener elements 12 (also referred to as individual fastener elements) and a string-like fixing member 15 (also referred to as a connecting member) that connects the plurality of fastener elements 12 at regular intervals.

[0051] The fixing member 15 is a flexible cord (also called a braided cord) formed by wrapping a core yarn composed of multiple paralleled multifilament yarns within a woven fabric knitted from multiple yarns. The fixing member 15 used in the present invention is not particularly limited as long as it can accommodate multiple zipper elements 12 and can be formed from, for example, monofilament or twisted yarn (twisted cord). The fixing member 15 has a generally circular cross-section perpendicular to its longitudinal direction, but the cross-sectional shape of the fixing member is not particularly limited in the present invention.

[0052] Each zipper element 12 of the element member 10 is formed by, for example, injection molding a thermoplastic resin such as polyacetal onto a fixing member 15, thereby being integral with the fixing member 15 and covering the entire outer peripheral surface of a portion of the fixing member 15. Furthermore, in the present invention, the material of the zipper elements 12 is not limited to the synthetic resins described above; other synthetic resins or metals may also be used to form the zipper elements. Furthermore, the element member of the present invention is not limited to a member formed by injection molding a zipper element onto a fixing member; for example, a member formed by attaching a zipper element pre-formed into a predetermined shape to a fixing member by welding or bonding may also be included.

[0053] like Figure 5 As shown, each zipper element 12 of the present embodiment includes: a main body portion 12a, which is fixed to a fixing member 15; a neck portion 12b, which extends in the width direction from the main body portion 12a and has a necked shape; an engaging head portion 12c, which further extends in the width direction from the neck portion 12b and is roughly oblong when viewed from above; and a shoulder portion 12d, which protrudes from the neck portion 12b to the front and rear in a thin plate shape.

[0054] The main body 12a of the zipper element 12 has a generally rectangular parallelepiped shape and is formed so that the fixing member 15 is enclosed in a manner that allows the fixing member 15 to penetrate in the front-to-back direction. In this case, the fixing member 15 is retained in the center of the thickness direction of the main body 12a. The neck 12b extends from the main body 12a in one direction in the width direction and is formed so that the length dimension (dimension in the longitudinal direction) of the neck 12b is reduced relative to the main body 12a. In addition, the neck 12b has a shape that is narrowed so that the length dimension is minimized at a predetermined position.

[0055] A groove portion 12e is formed along the length direction at the top end (tip portion) of the engaging head 12c, into which the shoulder 12d of the zipper element 12 on the engaging object side is embedded when the left and right tooth rows 11 are engaged. The upper and lower surfaces of the main body 12a, neck 12b, and shoulder 12d of each zipper element 12 are formed as parallel surfaces perpendicular to the thickness direction. In addition, the side wall surface of the main body 12a, which is arranged on the opposite side of the width direction of the neck 12b, is set as a surface that contacts the element mounting edge 7, and is formed as a plane perpendicular to the width direction. In addition, in the present invention, the shape and size of the zipper element are not particularly limited and can be changed arbitrarily.

[0056] like Figure 4As shown, gaps 16 are formed between the main bodies 12a of the zipper elements 12 adjacent in the longitudinal direction, through which the fixing members 15 are exposed. In each gap 16 formed between the zipper elements 12, the element member 10 is sewn to the fabric 6 by the fixing sewing portion 20 to be discussed later, so that the fixing member 15 is pressed and retained by the first sewing line 21 of the fixing sewing portion 20.

[0057] The above-described fastener element member 10 is fixed to the outer peripheral surface (first surface) 7a of the fastener element attachment edge 7 using a fixing stitching portion (fixing stitching line) 20. In this case, the fastener element member 10 is fixed along the longitudinal direction using the fixing stitching portion 20 at a position adjacent to the fastener element attachment edge 7, which is curved into a U-shape as described above, on the outside in the width direction. Furthermore, the fastener element member 10 is fixed to the fastener element attachment edge 7 such that the main body 12a of each zipper element 12 is in contact with a portion of the fastener element attachment edge 7.

[0058] The fixing sewing portion 20 is formed into a zigzag shape by sewing with a zigzag lockstitch sewing machine as will be discussed later, with the seam of the flat seam being partially bent relative to the longitudinal direction of the element member 10. The sewing lines forming the fixing sewing portion 20 include a first sewing line 21 arranged on the first surface (outer peripheral surface) 7a side of the element attachment edge 7 and a second sewing line 22 arranged on the second surface (inner peripheral surface) 7b side of the element attachment edge 7 (see FIG. Figure 3 and Figure 7 ). The first sewing thread 21 and the second sewing thread 22 of this embodiment use conventional general sewing threads. Figure 3 In FIG. 2 , a portion of the second sewing line 22 of the fixing sewn portion 20 that is disposed on the second surface 7 b (inner peripheral surface) is covered with the welding tape 40 and is therefore omitted from the illustration.

[0059] The fixing sewing portion 20 penetrates the element mounting edge 7 from the first surface (outer peripheral surface) 7a to the second surface (inner peripheral surface) 7b at the location where the sewing machine needle pierces the element mounting edge 7 at a predetermined needle drop position during sewing processing by a zigzag lockstitch sewing machine. In addition, the first sewing line 21 and the second sewing line 22 of the fixing sewing portion 20 intersect by interweaving only at the location where the fixing sewing portion 20 penetrates the element mounting edge 7.

[0060] Furthermore, the first and second stitching lines 21 and 22 intersect each other approximately at the center of the thickness direction of the element attachment edge 7. This allows the element attachment edge 7 to protect the intersection of the first and second stitching lines 21 and 22, making it difficult to see from the outside. Furthermore, the intersection position of the first and second stitching lines 21 and 22 in the thickness direction of the element attachment edge 7 can be easily changed by controlling the tension of the first and second stitching lines 21 and 22 in the zigzag lockstitch sewing machine.

[0061] In this embodiment, the fixing sewn portion 20 includes a main body side through-hole portion 23 that penetrates the main body side mounting edge portion 8 of the element mounting edge portion 7, and a folded-back side through-hole portion 24 that penetrates the folded-back side mounting edge portion 9 of the element mounting edge portion 7. In this case, the main body side through-hole portion 23 of the fixing sewn portion 20 is provided on the outer surface 6a side of the element mounting edge portion 7 exposed to the outside, and the folded-back side through-hole portion 24 is provided on the back surface 6b side of the element mounting edge portion 7.

[0062] In addition, when observing the cross section perpendicular to the front-back direction of the element attachment edge portion 7 in the state where the element member 10 is fixed (refer to Figure 3 ), the main body side through-hole portion 23 of the fixed sewn portion 20 is provided at a position closer to the element member 10 in the width direction than the folded-back side through-hole portion 24. As a result, the portion of the fixed sewn portion 20 (particularly, the first sewing line 21 of the fixed sewn portion 20) exposed to the outer surface 6a of the element mounting edge 7 can be reduced, thereby reducing the effect of the fixed sewn portion 20 on the aesthetics of the garment 1 with a zipper.

[0063] Furthermore, in the fixing sewn portion 20 of the present embodiment, for example Figure 1 、 Figure 2 ,as well as Figure 6 As shown, one main body side through-hole 23 is provided on the main body side attachment edge 8 for one fastener element 12 . On the other hand, three fold-back side through-holes 24 are provided on the fold-back side attachment edge 9 for one fastener element 12 .

[0064] By providing fewer main body-side through-holes 23 than fold-back through-holes 24 per zipper element 12, the fixing stitched portion 20 (particularly, the first stitching line 21 of the fixing stitched portion 20) can be made less conspicuous on the outer surface 6a of the element attachment edge 7 than on the back surface 6b of the element attachment edge 7. Consequently, the aesthetics or exterior quality of the zippered garment 1 can be further enhanced. Furthermore, by providing more fold-back through-holes 24 per zipper element 12 than main body-side through-holes 23, it is easier to securely secure the element member 10 to the element attachment edge 7.

[0065] Furthermore, in this embodiment, the number of main body-side through-holes 23 and the number of fold-back through-holes 24 provided for each zipper element 12 can be changed. In this case, it is preferable that the number of main body-side through-holes 23 provided for each zipper element 12 is less than the number of fold-back through-holes 24. For example, in this embodiment, two main body-side through-holes 23 or three or more main body-side through-holes 23 can be provided for each zipper element 12. Furthermore, when multiple main body-side through-holes 23 are provided for each zipper element 12, the positions of the first stitching line 21 and the second stitching line 22 can be changed one by one, or the first stitching line 21 and the second stitching line 22 can be made to intersect multiple times at the same position. Two fold-back through-holes 24 can be provided for each zipper element 12, or four or more can be provided. Furthermore, in the present embodiment, the fixing sewn portion 20 may be formed by changing the number of the main body-side through-holes 23 and the number of the fold-back-side through-holes 24 for each fastener element 12 .

[0066] like Figure 6 As shown, the fixing sewn portion 20 has a cross-section 25 between the main body side through-section 23 and the folded-back side through-section 24. In the cross-section 25, the first sewing line 21 crosses the fixing member 15 in a direction intersecting the longitudinal direction of the fixing member 15 and crosses the outer peripheral surface of the fixing member 15. In each cross-section 25 of the fixing sewn portion 20, the first sewing line 21 crosses the fixing member 15, thereby pressing the fixing member 15 against the element mounting edge 7 while holding it.

[0067] In the present embodiment, in each gap 16 between adjacent fastener elements 12 in the longitudinal direction, two cross-over portions 25 extend from one main body-side through-portion 23 toward each fold-back-side through-portion 24. Providing two cross-over portions 25 in each gap 16 between fastener elements 12 in this manner allows the element member 10 to be stably fixed to the element attaching edge 7.

[0068] Furthermore, in this embodiment, in the cross-section 25 of the fixed sewn portion 20, not only may the first sewing line 21 span the fixed member 15, but the first sewing line 21 and the second sewing line 22 may also penetrate the fixed member 15 and the element attachment edge 7 and intersect with each other. In other words, the fixed sewn portion 20 may include a retaining through portion midway along the cross-section 25, where the first sewing line 21 and the second sewing line 22 penetrate both the fixed member 15 and the element attachment edge 7 and intersect with each other. This allows the element member 10 to be more securely secured to the element attachment edge 7.

[0069] like Figure 1As shown, the slider 30 installed on the chain element array 11 of this embodiment has a slider body 31 and a pull tab 32 held on the slider body 31. The slider body 31 of this embodiment has substantially the same structure as the slider body commonly used for injection-molded zipper chain elements. That is, the slider body 31 of this embodiment has: an upper wing plate; a lower wing plate, which is separated from and arranged in parallel with the upper wing plate; a connecting column, which connects the front end of the upper wing plate and the front end of the lower wing plate (shoulder side end); upper and lower flange portions, which are arranged on the left and right side edges of the upper wing plate and the lower wing plate; and a pull tab mounting portion, which is arranged on the upper surface of the upper wing plate and holds the pull tab 32.

[0070] In addition, left and right shoulder openings are formed at the front end of the slider body 31, sandwiching the connecting post, and a rear opening is formed at the rear end of the slider body 31. A generally Y-shaped fastener element guide path is formed between the upper and lower wing plates, connecting the left and right shoulder openings and the rear opening. Using the slider 30 with this structure allows for smooth engagement and disengagement of the left and right fastener element members 10, which are directly secured to the fastener element mounting edge 7 of the garment 1.

[0071] Next, a method for manufacturing the slide fastener garment 1 according to the present embodiment having the above-described element member 10 will be described.

[0072] First, a pair of left and right element members 10 and a cloth 6 for clothing 1 are prepared. As described above, the element member 10 of this embodiment is manufactured by forming the fastener elements 12 on a single string-shaped fixing member 15 by injection molding of synthetic resin.

[0073] A pair of left and right front body fabrics 6 (fabric portion) having a predetermined shape as a member for attaching a zipper is produced independently of the element member 10. At this time, a pair of side edges disposed opposite to the left and right front body fabrics 6 serve as element attaching edges 7, respectively.

[0074] Next, a sewing process is performed to fix the element member 10 to the element attaching edge 7 of the fabricated cloth 6 using a zigzag lockstitch sewing machine.

[0075] In this sewing process, first, the portion of the element attachment edge 7 of the cloth 6 where the element member 10 is fixed is kept flat, and the element member 10 is sewn as shown in FIG. Figure 7 At this time, the fastener element member 10 is placed on the fastener element mounting edge 7 with the main body 12a of the fastener element 12 in contact with the fastener element mounting edge 7 and the engaging head 12c of the fastener element 12 facing upward and farthest from the fastener element mounting edge 7.

[0076] Next, the zigzag lockstitch sewing machine is used to sew the element member 10 to the element mounting edge 7 and the element member 10 in the upright position. At this time, the zigzag lockstitch sewing machine is pre-set with multiple coordinate data of needle drop positions. By using the zigzag lockstitch sewing machine, the element member 10 and the element mounting edge 7 of the fabric 6 are sewn together. Figure 6 and Figure 7 As shown, the above-mentioned fixing sewing portion 20 can be stably formed while the element member 10 is sewn to the element mounting edge 7 by the fixing sewing portion 20. In this embodiment, the fixing sewing portion 20 is formed by a flat seam, so that the element member 10 can be reliably fixed to the element mounting edge 7.

[0077] At this time, if Figure 7 As shown, a portion of the element attachment edge 7 and the fixing member 15 of the element member 10 are sandwiched and supported between the first stitching line 21 and the second stitching line 22 forming the fixing stitching portion 20. Thus, the fixing member 15 is held in a manner pressed toward the element attachment edge 7 by the first stitching line 21 and is therefore fixed to the element attachment edge 7.

[0078] In the sewing process of this embodiment, the above-mentioned main body side penetration portion 23 of the fixing sewing portion 20 is set at a ratio of 1 part for one zipper chain element 12, and the above-mentioned folding side penetration portion 24 of the fixing sewing portion 20 is set at a ratio of 3 parts for one zipper chain element 12.

[0079] The main body side through-hole 23 of the fixing sewing portion 20 is formed on the first surface 7a of the element attachment edge 7 in the cross direction X perpendicular to the longitudinal direction of the element member 10 (in other words, the feeding direction of the sewing machine) (see FIG. Figure 6 and Figure 7 ) is arranged at a position between the upper surface 12a1 of the main body 12a of the fastener element 12 and the fixing member 15. In addition, at least one of the folded-back through-portions 24 provided for one fastener element 12 is arranged at a position farther away from the fixing member 15 than the lower surface 12a2 of the main body 12a of the fastener element 12 in the above-mentioned cross direction X.

[0080] As described above, by making the relative positions of the main body side through-hole portion 23 and the folded back side through-hole portion 24 of the fixing sewn portion 20 different with respect to the fastener element member 10 in the cross direction X, when manufacturing the garment 1 with a zipper, Figure 3 As shown, the main body side penetration portion 23 can be provided at a position closer to the element member 10 than the fold-back side penetration portion 24 in the width direction.

[0081] After sewing with a zigzag lockstitch sewing machine, a portion of the element attachment edge 7, to which the element member 10 is fixed, is folded back so that the second surface 7b of the element attachment edge 7 faces each other, thereby forming the main body side attachment edge 8 and the folded-back side attachment edge 9. Simultaneously, a welding tape 40 is inserted between the main body side attachment edge 8 and the folded-back side attachment edge 9 and heated, thereby fusing the folded-back side attachment edge 9 to the main body side attachment edge 8 and securing it. Thus, a garment component can be produced in which the element member 10 is secured to the left and right sides of the element attachment edge 7 by the fixing sewing portion 20.

[0082] After that, the garment components are combined to assemble the garment 1. Furthermore, the slider 30 is slidably mounted on the element row 11 formed by fixing the element member 10 to the element mounting edge 7. Thus, the garment 1 can be stably manufactured. Figure 1 Such a zippered garment 1 is shown.

[0083] The zippered garment 1 of this embodiment manufactured as described above can function as a zipper 5 without the zipper tape required in conventional zippers. This can reduce manufacturing costs, reduce weight, and improve the flexibility of the zippered garment 1.

[0084] In addition, in the zippered garment 1 of this embodiment, Figures 1 to 3 As shown, the second sewing line 22 of the fixing sewn portion 20 can be hidden in the inner peripheral surface (second surface) 7b of the element mounting edge 7, and the portion of the fixing sewn portion 20 exposed to the outer surface 6a of the element mounting edge 7 can be reduced. As a result, the fixing sewn portion 20 can be less visible from the outside of the zippered garment 1, thereby reducing the impact of the fixing sewn portion 20 on the appearance quality of the garment 1 and improving the aesthetics of the garment 1.

[0085] Furthermore, in the zippered garment 1 of the above-described embodiment, the fixing stitched portion 20 that secures the element member 10 to the element attachment edge 7 is formed with a flat seam. However, in the present invention, the fixing stitched portion 20 that secures the element member 10 to the element attachment edge 7 may also be formed with a chain stitch. Even in a zippered garment in which the fixing stitched portion 20 is formed with a chain stitch, the same effects as those of the zippered garment 1 of the above-described embodiment can be achieved.

[0086] In the above-described embodiment, for example, for waterproofing purposes, the fabric 6 forming the garment may be coated with a synthetic resin, or a waterproof membrane member may be bonded to the fabric 6 forming the garment. Furthermore, the fastener element attachment edge 7 of the fabric 6 and its vicinity may be reinforced by impregnation with a reinforcing agent or bonding a reinforcing membrane member.
