The present invention relates to a chain without a zipper chain which is formed by fixing a continuous zipper element formed by a monofilament to a narrow sprocket fixing member, and a zipper attached to the chain belt having the zipperless chain cloth. article.

The zipper is often used as an opening and closing member for articles such as clothes, household groceries, industrial materials, and various types of seats such as automobiles, trains, and airplanes. The zipper for the opening and closing portion of various articles generally includes: a pair of zipper chain belts, which are formed with a chain of teeth on a side edge portion of the zipper chain cloth; and a sliding member slidably along the sprocket row Configuration.

Further, as an example of a typical fastener stringer, there is known a fastener stringer having a continuous fastener element which is formed into a loop shape or a zigzag shape by a thermoplastic resin monofilament. A plurality of meshing heads are joined into a series. In the fastener stringer, a fastener element row is formed by suturing and fixing a continuous fastener element to a side edge portion (sprocket attachment portion) of a woven or knitted fastener stringer by a suture.

An example of a zipper that forms a sprocket row by such a continuous zipper element is disclosed in Japanese Laid-Open Patent Publication No. 2006-247279 (Patent Document 1).

As shown in FIG. 13, the zipper 100 described in Patent Document 1 includes a pair of fastener tapes 103 which are sewn to the side of the fastener zipper 102 by a sewing thread. a sprocket mounting portion on the rim side; and a slider 104 mounted on the element row of the continuous zipper elements 101. In this case, the fastener stringer 102 includes a wide chain main body portion and a fastener attachment portion that is disposed on one side edge side (inner side edge side) of the chain main body portion.

Further, when the zipper 100 is sewn to an article such as a garment as a zipper-attached member, the main body portion of the fastener zipper 102 is attached to the upper surface side of the fastener zipper 101 by the sewing machine. When the fastener stringer 103 is observed, the portion of the chain cloth that is extended to the outside of the continuous fastener element 101 is sewed in a state in which the opening/closing portion (opening peripheral portion) of the zipper attachment portion of the article is overlapped.

Further, for example, in the specification of International Publication No. 2012/070116 (Patent Document 2) or International Publication No. 2011/111154 (Patent Document 3), a slide fastener having improved fastener tape is disclosed.

For example, Patent Document 2 discloses a fastener stringer 110 for a slide fastener, that is, as shown in FIG. 14, the fastener stringer 111 is extended beyond the edge of the joint portion side of the continuous fastener element 112, but is externally The elongation (X) is limited in a manner less than 12 mm.

In the case of the fastener stringer 110 of the patent document 2, when the fastener stringer 110 is attached to an article in the state which bends the fastener chain 111, for example, the following effect is obtained, even if the fastener chain 111 is bent. The fastener main body portion can be stably sewn while the main body portion of the fastener fabric 111 is held substantially flat.

Further, Patent Document 3 discloses a fastener stringer 120 for a slide fastener, that is, as shown in FIG. 15, which is configured such that a fastener element row formed by continuous fastener elements 121 is wrapped by a fastener chain 122. By using the fastener stringer 120 of Patent Document 3 to form a slide fastener, when the left and right fastener element rows are engaged, the fastener element can be shielded from the outside by the fastener chain cloth 122 without using the covering body. Improves the appearance of items with zippers.

Patent Document 3: International Publication No. 2011/111154

In recent years, in various articles, especially clothing, such as clothing, bags, and footwear, zippers attached to them have become more and more regarded as an element of design, and it is therefore required to improve the overall contents of the zipper-containing articles. The appearance quality. In addition, in the past, the zipper is attached to the zipper-attached member in a state in which the zipper is bent in a curved shape or the like from the viewpoint of convenience or design of the article.

In the zipper of the prior art described in the above Patent Documents 1 to 3, the main body portion of the fastener fabric to which the fastener stringer having the continuous fastener element is fixed is sewn and fixed to the zipper attachment member (for example, clothing). Use, etc., for the opening and closing. Therefore, in order to smoothly sew the zipper and the zipper-attached member by the sewing machine, it is necessary to ensure the width of the zipper main body of the zipper chain which is exposed to the outside in the width direction of the fastener as the sewing allowance.

Further, since the zipper chain cloth for a zipper is woven or knitted, it is usually made thinner in the thickness direction of the chain fabric (the thickness is small). At the same time, in order to ensure that the width dimension of the main body portion of the fastener fabric of the fastener stringer is smoothly sewn by the sewing machine as the sewing allowance as described above, and it can be stably sewn to various zipper-attached members, the zipper chain is woven. The main body of the chain fabric is formed to be wide in the width direction of the chain fabric.

In the zipper of the prior art, the zipper chain is formed in a thinner direction in the thickness direction and wider in the width direction. Therefore, when the zipper is attached to the zipper-attached member in a straight line, the zipper can be beautifully sewn to the seat. . However, in the case where the zipper is attached to the zipper-attached member in a state in which the zipper is bent or the like, there is a case where the main body portion of the zipper that is in contact with the outer peripheral portion of the zipper is partially raised or sagged partially, or The gusset extension portion (the extension portion of the chain cloth bent in a concave shape) which is in contact with the inner peripheral portion of the zipper generates a large undulation of wrinkles.

When the extension portion of the chain cloth is largely raised as described above, it is impossible to The sewing machine presser foot accurately presses the zipper chain cloth, and in the case of, for example, a large undulation of wrinkles in the extension portion of the chain cloth, since the zipper chain cloth partially overlaps, it is difficult to use the sewing machine to the zipper. Sewing with the attached member of the zipper.

Moreover, even in the article in which the zipper is sewn (the article with the zipper), if the zipper chain cloth has a large bulging or sag, or an undulating wrinkle, there is also an appearance of lowering the zipper-attached article ( The problem of appearance quality). Further, when the slider is slid along the element row, the fastener chain cloth is apt to be in sliding contact with the slider, and therefore, the sliding resistance of the slider is increased to lower the slidability of the slider.

The present invention has been made in view of the above problems, and a specific object thereof is to provide a zipper-free chain belt and a zipper-attached article using the zipper-free chain belt, the zipper-free chain cloth The chain belt can reduce the weight and cost of the zipper, and can be attached to the zipper-attached member with good appearance even in a state in which the bending is curved.

In order to achieve the above object, the most important feature of the zipper-free chain strap provided by the present invention is that it comprises: a continuous plurality of zipper fasteners, which are formed by monofilaments; and a narrow-width fastener element. Sewing the fastener element by a stitching line; and the fastener element includes: an engaging head; an upper and lower leg extending from the engaging head in a width direction of the zipper; and a connecting portion, The upper leg portion or the lower leg portion is extended to be coupled to the fastener element in the longitudinal direction of the zipper; the fastener element is inserted between the upper and lower leg portions of the fastener element along the longitudinal direction of the zipper, and the sewing is performed. The upper leg portion and the lower leg portion of the respective fastener elements are in contact with the upper leg portion and the lower leg portion of each of the fastener elements, and the above-mentioned fastener elements are adjacent to each other in the longitudinal direction of the slide fastener. The fastener element is fixed to the fastener element and the fastener element is stitched to the fastener element.

In the zipper-free chain link of the present invention, the sprocket fixing member is preferably In the unloaded state, it has a size in the width direction of the zipper which is twice or more the size in the thickness direction of the zipper.

In the fastener tape of the zip fastener chain of the present invention, the fastener element is preferably a chain member having a braided structure. Further, the fastener element fixing member may be a chain fabric member having a warp knitting structure in which a crochet line is disposed in each of the warps, a chain fabric member including a non-woven fabric, or a film member made of a synthetic resin.

Further, it is preferable that the upper and lower leg portions are sewn to the element fixing member by a double-thread chain slit of the sewing line.

Moreover, according to the present invention, it is possible to provide a zipper-attached article, the most important feature of which is that the zipper-free chain link having the above-described configuration is attached to the opening and closing portion of the zipper-attached member. And sliding the sliding member to the chain of teeth formed by the above-mentioned fastener elements.

The fastener tape without the zipper chain provided by the present invention comprises continuous zipper fasteners formed of monofilaments and having a loop-like shape or a zigzag shape, and a narrow-width fastener element. Further, the narrow sprocket fixing member is inserted between the upper and lower leg portions of the fastener element along the longitudinal direction of the zipper, and the continuous zipper element is stitched in series by the sewing line to be disposed between the upper and lower legs. A narrow-width fastener element.

Here, the zipper chain is used to mean the outer surface of the foot or lower leg above the sprocket (the opposite side to the upper and lower leg) to contact the upper or lower leg. In the state, the link member of the upper leg portion and the lower leg portion is fixed, and is a member different from the fastener element fixing member of the present invention inserted between the upper and lower leg portions. That is, the fastener stringer of the present invention is not provided with a so-called zipper chain cloth for fixing the upper leg portion and the lower leg portion on the outer side of the upper leg portion or the lower leg portion, and is configured to have a different function from the conventional zipper tape. A new construction of a chain without a zipper chain.

Moreover, in the present invention, the sewing thread is in contact with the upper part of each of the fastener elements by one side And the lower leg portion spans the foot portion and the lower leg portion of each of the fastener elements, and pierces the fastener element between the fastener elements adjacent to each other in the longitudinal direction of the zipper, and the continuous fastener element is sewn and fixed to the chain. Tooth fixing member. In this case, the fastener element fixing member preferably has a structure that is difficult to expand and contract in the longitudinal direction of the zipper, and is not easily stretchable in the longitudinal direction of the zipper as in the prior art.

The zipper chain belt (the zipper-free chain belt) of the present invention which does not use the zipper chain cloth sutures the zipper element to the fastener element which is inserted between the upper and lower legs (especially the chain which is difficult to stretch) Tooth fixing member). Therefore, even if the zipper tape as in the prior art is not used as the constituent member of the fastener stringer, the mounting pitch of the fastener elements can be stably maintained by the fastener element.

Therefore, by attaching the fastener tape of the present invention to the zipper-attached member to form the zipper-attached article, the weight of the zipper-attached article can be reduced and the cost can be reduced, or it can be compared with the previous one. A zipper cloth is used for a different purpose (for example, for decorative purposes, etc.).

Further, in the present invention, the fastener stringer or the zipper can be formed without using a fastener chain cloth. Therefore, for example, the fastener tape of the zipper-free fastener of the present invention can be stably attached to the zipper in a state of being bent or curved. member. Moreover, in this case, the zipper of the zipper which is regarded as a problem in the previous zipper is not swelled or sagged, or the undulations are creased, etc., so that the appearance of the zipper-attached article can be improved (appearance quality) ).

[Examples]

Fig. 1 is an enlarged view of a main portion showing a main portion of the zipper-attached article of the present embodiment enlarged from the back side. Fig. 2 is a perspective view showing an enlarged main portion of the zipper-attached article, and Fig. 3 is a cross-sectional view of the zipper-attached article. 4 and 5 are a plan view and a bottom view of a chain link without a zipper chain attached to the zipper-attached article.

Further, in the description relating to the following zipper, the front-rear direction refers to the longitudinal direction of the zipper or the longitudinal direction of the chain member, and in particular, the direction in which the slider is slid in such a manner that the fastener elements of the zipper are engaged. In the front, the direction in which the slider slides so that the element rows are separated is set to the rear.

In addition, the left-right direction means the width direction of the slide fastener, and is the direction orthogonal to the chain surface of the fastener element of a fastener, and the direction orthogonal to the longitudinal direction of the fastener. Further, the vertical direction means a direction orthogonal to the front-rear direction and the left-right direction, and is, for example, a thickness direction of the link orthogonal to the chain surface of the chain member. In particular, the direction of the side of the slider on which the slider is disposed with respect to the fastener element is set to the upper side, and the direction of the opposite side is set to the lower side.

The zipper-attached article 1 of the present embodiment is a garment (clothing), and the zipper is formed in an opening and closing portion of the opening portion of the front piece of the garment 1, or a pocket portion of the chest and the abdomen of the front piece. Opening and closing portion (opening peripheral portion) and the like. That is, in the present embodiment, the zipper attached to the zipper is attached to the fabric 5 of the garment 1 (also referred to as a garment fabric).

In this case, the zipper of the present embodiment is disposed on the back side (inner side) of the cloth 5 of the garment 1 so that the fastener element row 11 of the fastener stringer 10 is not easily seen from the outer surface side of the garment 1. The so-called counter-installation is installed on the clothes 1. Also, as shown in FIG. 2, in the clothes 1 In each of the opening and closing portions, the left and right fabrics 5 can be arranged to face each other in abutment/separation by opening and closing of the zipper.

Further, in the present invention, the article to which the zipper is attached is not limited to clothes (clothing), but also includes items such as daily sundries such as shoes and bags, articles for industrial materials, and various seats such as automobiles, trains, and airplanes. Various items such as classes.

As shown in FIG. 2 and FIG. 3, the zipper of the garment 1 of the present embodiment includes: a pair of left and right fastener chain belts (chain belts without a zipper chain) 10, and the like, including a chain row 11; 30, which is slidably disposed along the sprocket row 11; a first stop 41 disposed adjacent to the front end of the sprocket row 11 to prevent the slider 30 from falling off; and a second stop 42, which is associated with the sprocket row The rear ends of 11 are adjacent and arranged to straddle the left and right zipper chain belts 10.

Each of the left and right fastener chain belts 10 includes: a fastener element 12 which is continuous in a loop shape; and a narrow chain member 14 which is fixed by the stitching of the first stitching line 13; and each of the fastener chains The belt 10 is configured as a fastener tape 10 without a fastener chain on the outer side of the leg portion 12b and the outer side of the lower leg portion 12c of the fastener element 12.

The fastener element 12 is formed by molding a thermoplastic resin monofilament such as polyamide or polyester into a loop shape, and includes: an engaging head portion 12a having a portion bulging in a front-rear direction; and an upper leg portion 12b And the lower leg portion 12c extending from the meshing head portion 12a in the width direction; and the connecting portion 12d connecting the leg portion 12b (or the lower leg portion 12c) of the continuous fastener element 12 and the adjacent one in the longitudinal direction of the zipper A zipper element 12 is located between the foot portion 12c (or the upper leg portion 12b).

Further, as the fastener element 12 of the present invention, in addition to the fastener element 12 formed by winding the monofilament into a loop shape as described above, the monofilament may be bent into a zigzag shape as described above. And the zipper teeth formed.

As shown in Fig. 7, the narrow chain member 14 which is a fixing member for fixing the fastener element 12 is formed of a plain weave structure which is formed by a plurality of warp yarns 14a and two single wires. The weft 14b as one set is woven by a single layer weaving.

The chain fabric member (woven chain fabric member) 14 woven into such a plain weave structure has a flat cross-sectional shape in which the dimension in the thickness direction is small and the dimension in the width direction is large, and is woven by the weft 14b. The wire 14a suppresses the expansion and contraction of the zipper in the longitudinal direction and is difficult to expand and contract. Further, at one side edge portion of the woven chain fabric member 14, a side portion formed by sequentially hooking the next weft thread 14b to join the loop-shaped folded end is formed.

As shown in FIGS. 4 to 6, the woven chain fabric member 14 is inserted into the upper and lower leg portions 12b and 12c of the fastener element 12 in the longitudinal direction of the zipper, and is wound by the first sewing thread 13. The portion 12b and the lower leg portion 12c are fixed to the front surface and the back surface of the braided chain member 14. The first stitching line 13 is a first fixing mechanism in which the fastener element 12 is attached to the braided chain member 14 (fixing member).

In particular, in the present embodiment, the woven chain member 14 and the fastener element 12 are inserted into the inner space formed between the lower leg portions 12b and 12c of the fastener element 12, and the chain is used. The sewn sewing machine is sewn into a series by the double stitching of the first sewing thread 13. Further, the fastener element 12 which is continuous in a loop shape is integrally sewn and fixed to the braided chain member 14 throughout the longitudinal direction of the slide fastener.

In the present embodiment, by having a flat shape as described above in the cross section of the woven chain member 14, the woven chain member 14 can be easily inserted between the lower leg portions 12b, 12c of the fastener element 12, and When the upper and lower leg portions 12b and 12c are sewn to the knitted chain member 14 by using a sewing machine, for example, the sewing machine needle is stably pierced by the knitting chain member 14 to smoothly perform the sewing operation.

In this case, the hook line 13a of the first stitching line 13 is attached to the front side of the woven chain member 14, and is in direct contact with the upper leg portion 12b of the fastener element 12 and spans the upper leg portion 12b. The needle thread 13b of the sewing thread 13 is attached to the back side of the woven chain member 14, directly in contact with the lower leg portion 12c of the fastener element 12 and spans the lower leg portion 12c, and is woven between the mutually adjacent fastener elements 12 The link member 14 is interlaced with the thread hook line 13a passing through the front side of the braided link member 14. Thereby, stitches are formed between the respective zipper elements 12, and The first sewing portion formed by the double-thread chain stitch of the first sewing line 13 is formed so as to face the front side and the back side of the element row 11.

By fixing the fastener element 12 to the braided chain member 14 which is difficult to expand and contract in the longitudinal direction of the fastener by the double-thread chain stitch of the first stitching line 13, the braided chain member 14 can be used as the fastener element to hold the fastener element. The shape of 12, and the mounting pitch of the fastener elements 12 (in other words, the interval between the engaging heads 12a) can be kept constant.

Further, since the first stitching line 13 pierces the braided link member 14 and holds the fastener element 12, the first stitching line 13 is not easily offset with respect to the piercing position of the braided link member 14, so that the fastener element 12 can be attached. The upper and lower leg portions 12b, 12c are fixedly supported at a specific position of the braided link member 14. Therefore, it is possible to prevent the upper and lower leg portions 12b, 12c from moving relative to the braided link member 14.

Further, since the double-thread chain stitch is used as the stitching form of the first stitching line 13, the strength of the stitch is excellent and the stretchability is also excellent, and further, even if the first stitching line 13 is broken, the first stitching line is used. 13 is also not easy to open. Further, by stitching the woven chain fabric member 14 and the fastener element 12 with a double-thread chain stitch, the fastener tape 10 without the fastener chain can be manufactured with high productivity. Further, in the present invention, as the stitching form of the first stitching line 13, it is also possible to use a chain stitch or the like in addition to the double-thread chain stitch.

Further, the fastener stringer 10 of the present embodiment configured as described above removes the fastener stringer which is an essential constituent member of the prior fastener stringer, and therefore is lighter than the conventional fastener stringer, and can be Manufacturing costs are kept low.

Further, since the fastener element 12 is sewn to the woven chain member 14 having a structure that is difficult to expand and contract in the longitudinal direction of the zipper, the zipper element 12 can be stably held by the woven chain member 14 even if the fastener zipper is removed. Installation spacing. Further, even if the chain belt 10 without the fastener chain is bent into a curved shape or the like, it does not cause ridges or sag or undulation wrinkles of the fastener chain as in the case of the conventional fastener tape.

The chain link 10 of the zipperless chain cloth is as shown in Figs. 8 and 9, and is opposite to the zipper. In the state in which the cloth 5 of the garment 1 is aligned, the zipper sewing machine is sewn and fixed to the fabric 5 by the interlocking slit of the second sewing thread 6. In this case, the fastener element 12 and the braided chain member 14 are integrally sewn to the fabric 5 throughout the longitudinal direction of the fastener. Further, the second sewing line 6 is a second fixing mechanism in which the fastener stringer 10 is attached to the fabric 5.

In particular, in the present embodiment, the second stitching line 6 is caused to straddle the upper and lower leg portions 12b and 12c of the fastener element 12, and to pierce the braided link member 14 and the cloth 5 between the adjacent fastener elements 12, The fastener tape 10 without the zipper chain is sewn to the fabric 5.

In this case, the sewing of the interlocking stitches by the second stitching line 6 is performed using a ball-end needle as a sewing machine needle. The tip end of the round needle is rounded into a spherical needle, and the diameter of the tip end thereof is preferably 0.2 mm or more and 0.6 mm or less.

By using the ball-shaped needle as described above, even if the sewing machine needle collides with the fastener element 12 at the time of sewing, the position of the ball-end needle can be relatively reversed in the front-rear direction along the fastener element 12 while the knitting chain is pierced. Since the cloth member 14 and the cloth 5 are used, the damage of the fastener element 12 and the breakage or bending of the sewing machine needle can be avoided, and the sewing step can be smoothly and stably performed.

Further, by using the interlocking stitch as the stitching form of the second stitching line 6, it is possible to obtain the advantage that the stitches of the second stitching line are not easily unwound and the strength is excellent, and the round needle collides with the fastener element 12 even when sewing. The position of the ball (in other words, the position of the needle-punched chain member 14 and the cloth 5) is offset, and the chain 10 and the cloth 5 without the fastener chain can be smoothly and stably stitched.

Further, in the case where such a sewing by the second sewing thread 6 is performed, when the ball is hit by the fastener element 12, the fastener element is in the chain 10 of the fastenerless chain of the present embodiment. 12 is suitably fixed to the woven chain member 14 as described above, so that the fastener element 12 can be allowed to move slightly in a manner avoiding the round pin, and the fastener element 12 held by the woven chain member 14 can be prevented. The pitch becomes uneven.

Further, in the present embodiment, the second sewing portion (particularly, the portion where the second sewing line 6 is exposed on the element row 11) formed by the stitching stitches of the second stitching line 6 is in the width direction of the slide fastener. It is disposed so as to overlap the formation range of the first sewing portion formed by the double-thread chain slit of the first sewing line 13. Here, the second sewn portion is located in the range in which the first sewn portion is formed, and the second sewn portion formed on the surface of the element row 11 (the outer surface of the leg portion 12c below the fastener element 12) is disposed. The first sewing portion formed on the surface of the element row 11 (the outer surface of the leg portion 12c below the fastener element 12) is in the range of the chain width direction.

Further, the second sewing line 6 on which the second sewing portion is formed on the element row 11 (particularly, the outer surface of the leg portion 12c on the lower side of the fastener element 12) is passed between the adjacent leg portions 12c of the adjacent fastener elements 12. The woven chain fabric member 14 is pierced, and the fabric 5 is pierced by the space between the leg portions 12b of the adjacent fastener elements 12. In this case, a portion of the first sewing line 13 also has a portion between the second sewing line 6 and the outer surface of the leg portion 12c below the fastener element 12.

Further, the fastener element 12, the braided chain member 14, and the cloth 5 are the second sewn portion which is a part of the second sewn line 6 which is sandwiched between the element rows 11, and the first surface which is exposed on the surface of the cloth 5. 2 The stitching line 6 is fixed by stitching between one of the parts.

By forming the second sewn portion of the second sewn line 6 so as to overlap the first sewn portion of the first sewn line 13 as described above, the second sewn portion is difficult to distinguish from the first sewn portion. It is not easy to be noticed, and therefore, the appearance of the garment 1 to which the fastener tape 10 is attached can be improved.

In addition, since the second sewing portion and the first sewing portion are formed on the surface of the fastener element 12 together with the fastener tape 10 being fixed to the fabric 5, the first sewing portion and the second sewing portion can be used. Both suffer from wear due to sliding of the slider 30 or wear and collision due to external factors. Therefore, compared with the case where the second sewn portion is formed away from the first sewn portion, the first sewn line 13 and the second sewn line 6 are less likely to be broken.

Further, by arranging the second sewing portion so as to overlap the first sewing portion, the fastener tape 10 and the cloth can be sewn in the vicinity of the opposite side edges of the cloth 5. By this, The side edge portion of the cloth 5 located in the inner side of the second sewing portion in the width direction of the zipper is less likely to be bent (rolled). Therefore, when the left and right fastener elements 12 are engaged, the opposite side edges of the left and right cloths 5 can be brought close to each other (or contact), and the element rows 11 are not easily seen from the left and right cloths 5 (or are not visible).

In the case where the second sewing portion formed by the second sewing line 6 is formed so as to overlap the first sewing portion formed by the first sewing line 13, the above-described second sewing portion can be used as described above. As described above, the needle is used as the sewing machine needle, and the needle tip of the ball is separated from the first stitching line 13 to be sewn by the line. Therefore, the first stitching line can be used when the second stitching line 6 is sewn. 13 is not easy to cut off. Further, in the present invention, as the stitching form of the second stitching line 6, it is also possible to use a stitching slit.

As described above, after the pair of fastener-free chain links 10 are sewn to the fabric 5 of the garment 1 by the interlocking stitches of the second stitching line 6, the slider 30 is slidably attached to the two fastener stringers 10 The chain of teeth 11. Further, the first stopper 41 and the second stopper 42 are formed to be adjacent to the front end and the rear end of the element row 11.

As shown in FIG. 2 and FIG. 3 and the like, the slider 30 of the present embodiment includes a slider main body 31 and a pull tab 32 having a mounting shaft portion at one end. Further, the slider main body 31 includes: an upper wing plate 33; a lower wing plate 34 which is disposed apart from the upper wing plate 33 and arranged in parallel; and a guide post 35 which connects the front end portions of the upper and lower wing plates 33, 34 (introduction port side end) The lower flange portion 36 is erected from the left and right side edge portions of the lower blade 34 toward the upper blade 33; the protruding portion 37 is disposed on the left and right side edge portions of the upper blade 33; and the pull tab The mounting portion 38 is disposed on the upper surface of the upper blade 33.

At the front end portion of the slider main body 31, a left-right introduction port is formed by sandwiching the guide post 35, and an engagement opening is formed at an end portion of the slider main body 31. Further, a sprocket guiding path is formed between the upper and lower flaps 33 and 34, and the sprocket guiding path is formed in a substantially Y shape so as to communicate with the left and right introduction ports and the engaging opening, and can be inserted by the zipper element 12 and the cloth 5 through.

The first stop 41 of the embodiment is such that the slider 30 does not come off from the front end side of the element row 11 The falling mode is attached to the cloth 5 adjacent to the front end of the left and right element rows 11 . Further, the second stopper 42 is attached to the cloth 5 so that the slider 30 does not fall off from the rear end side of the element row 11 and is adjacent to the rear end of the left and right element rows 11 and across the left and right element rows 11 .

Further, in the present invention, the method of attaching the first and second stoppers 41 and 42 to the cloth 5 is not particularly limited, and for example, the first and second stoppers 41 and 42 may be fixed by welding or welding. In the cloth 5, the first and second stoppers 41 and 42 made of metal can be plastically deformed by press working or the like, and the same can be fixed to the cloth 5.

Further, in the present invention, instead of the second stopper 42, the separable insert may be provided adjacent to the rear end of the element row 11. Further, the second stopper 42 may be formed by, for example, pressing the rear end portion of the element row 11 to press the end portion of the element row 11 to be wide, or The rear end portion of the element row 11 is sutured in a traversing manner.

Furthermore, in the present embodiment, after the pair of fastener tapes 10 without the fastener chain are sewn to the fabric 5, the slider 30 is attached to the fastener element row 11 of the chain and the first stop 41 and the first The 2 stopper 42 is attached to the cloth 5.

However, in the present invention, after the slider 30 is attached to the element row 11 of the pair of fastener tapes 10, the chain is sewn by the stitching of the second stitching line 6. Cloth 5. Further, in consideration of the efficiency or productivity of the sewing by the second sewing line 6, it is preferable to suspend the fastener tape 30 and the first stop 41 after sewing the fastener tape 10 without the fastener chain to the fabric 5. Installation of the second stop 42.

In the garment 1 with a zipper of the present embodiment configured as described above, the zipper can be formed without using a fastener chain cloth, so that the weight of the zipper can be easily reduced and the cost can be reduced.

Further, in the case where the fastener tape 10 without the fastener chain is bent in a curved state or the like, for example, when it is attached to the opening and closing portion of the pocket portion of the chest or the abdomen of the garment 1, the previous zipper does not occur. The appearance of the garment 1 (appearance quality) can be improved by the bulging or sag of the zipper chain cloth of the problem or the undulation of the undulations.

Further, in the attachment of the fastener tape 10 without the fastener chain, the attachment of the fastener tape 10 without the fastener chain can be easily and stably performed by using the sewing machine having the round needle. Therefore, the garment 1 can be beautifully processed by a relatively simple sewing step.

Furthermore, in the present invention, instead of the continuous fastener element 12 of the loop shape as shown in FIGS. 2 and 3, a continuous fastener element 22 such as a loop shape as shown in FIG. 10 may be used. Chain link 20 without zipper chain.

The fastener element 22 for the fastener tape 20 of the zipper-free chain shown in FIG. 10 is formed by forming a monofilament made of a thermoplastic resin into a loop shape, and includes: an engaging head 22a having a direction a portion that bulges in the front-rear direction; an upper leg portion 22b and a lower leg portion 22c that extend in the width direction from the meshing head portion 22a; and a coupling portion 22d that connects the leg portion 22b (or the lower leg portion) of the continuous fastener element 22 22c) and another zipper element 22 adjacent to the zipper length direction between the lower leg portion 22c (or the upper leg portion 22b).

Further, the leg portion (in this case, the lower leg portion 22c) on the side of the fastener element 22 that is not in contact with the cloth is directed to the other leg portion on the side in contact with the cloth (in this case, the upper leg) The portion 22b) is partially recessed, and a concave portion 22e for arranging (accommodating) the first sewing line 13 is formed on the outer surface of the one leg portion (the lower surface of the lower leg portion 22c).

By providing such a recessed portion 22e on the lower surface of the lower leg portion 22c, and the first stitching line 13 restrains the upper and lower leg portions 22b and 22c so as to straddle the recessed portion 22e, the upper and lower leg portions 22b and 22c are sewn to the woven chain. When the fastener tape member 20 is attached to the fabric and the slider 30 is slid, the first sewing thread 13 is less likely to come into contact with the slider 30, and the abrasion of the first sewing thread 13 is less likely to occur.

Further, in this case, the second stitching line 6 for sewing the fastener tape 30 without the fastener tape to the cloth 5 is disposed so as to straddle the concave portion 22e of the lower leg portion 22c similarly to the first stitching line 13. Further, it is possible to make it difficult for the second sewing line 6 to come into contact with the slider 30, and it is difficult to cause abrasion of the second sewing line 6. Therefore, in the article to which the fastener tape 20 having no zipper chain cloth shown in Fig. 10 is attached, even if the sliding operation of the slider 30 is repeated, it is difficult to produce the first stitching line 13 Further, the cutting of the second sewing line 6 can maintain the function of the zipper for a long period of time and stably.

Further, by deforming the lower leg portion 22c of the fastener element 22 so as to partially recess toward the upper leg portion 22b as described above, the braided link member 14 can be stably held between the upper and lower leg portions 22b, 22c. . Thereby, the positions of the upper and lower leg portions 22b and 22c with respect to the woven chain link member 14 can be made more difficult to be displaced in the longitudinal direction of the zipper, and the distance between the fastener elements 22 can be made more stable.

Further, in the linkless belt 10 of the above-described embodiment, a narrow-width chain member 14 woven into a plain weave structure is used as a chain disposed between the lower leg portions 12b and 12c of the fastener element 12; The tooth fixing member, but in the present invention, in addition to the braided chain member 14, such as the narrow chain member (warp knitted fabric member) 51 shown in Fig. 11, a non-woven fabric may be used. The narrow-width chain member, or a narrow-width film member 52 formed of a synthetic resin having a property of being difficult to stretch, as shown in FIG.

The sprocket fixing members are configured such that the dimension in the width direction of the pull-down chain (also referred to as the width direction of the chain fabric) in the unloaded state is twice or more the size of the thickness direction of the chain fabric, and more preferably, the fastener element is fixed. The dimension of the zipper width direction of the member is set to be 2.5 times or more and 3.5 times or less the size of the chain thickness direction.

Here, the unloaded state refers to a state in which the fastener element is pulled out from the fastener element 12, and an external force such as stretching or compression is not applied to the fastener element. Since the fastener element has the size as described above, it can be provided with a structure that is difficult to expand and contract in the longitudinal direction of the zipper.

Here, the previous core cord disposed between the lower leg portions of the fastener element is mostly a braided cord which is obtained by braiding a plurality of strands around the strand in a state in which a plurality of strands are arranged in a bundle. In the braided cord in which a plurality of strands are bundled in this manner, the plurality of strands extend in the longitudinal direction of the zipper, but each of the strands has undulations (crimping) in the width direction of the zipper and the thickness of the zipper, so that the braided cord is easily stretched.

Moreover, the previous core rope has a circular cross section under no load, so it is pulled Both the chain width direction and the zipper thickness direction are free to undulate, so that it is easy to generate a large amount of undulations, and as a result, the core rope is easily stretched and contracted along with the occurrence of the undulation.

On the other hand, the sprocket fixing member of the present invention has a structure in which it is difficult to expand and contract because the undulation generated by the previous core string is less generated. Further, when the tensile force in the longitudinal direction of the zipper is applied to the fastener element of the present invention, the cross-sectional shape (especially the dimension in the thickness direction of the chain fabric) becomes smaller than the unloaded state, and the amount of reduction is related to the length of the zipper. Extension. Therefore, the sprocket fixing member is made smaller in size in the thickness direction of the link fabric than in the width direction of the chain fabric, so that the cross-sectional shape of the sprocket fixing member when the tensile force is applied is not easily reduced, and thus it becomes difficult. The structure of the telescopic.

For example, the size of the fastener element in the width direction of the fastener is set to be twice or more the size of the thickness direction of the fastener, and for example, the size of the chain width direction of the fastener element is set to be the chain. The sprocket fixing member is difficult to extend in the longitudinal direction of the zipper as compared with the case where the thickness direction of the cloth is equal or 1.5 times the size of the cloth.

Further, for example, the warp knit fabric member 51 shown in Fig. 11 includes a warp-knitted narrow strip-shaped body and has a warp-knitted single-layer structure. Further, the entire chain width of the warp knit fabric member 51 is composed of the first warp W1 to the seventh warp W7. The braided structure of the warp knit fabric member 51 includes crochet stitches 51a (0-1/1-0), Cuikut warp knitting yarns 51b (1-0/1-2), and crosses arranged in each warp. And four weft insertion threads 51c (4-4/0-0) which are inserted in a zigzag pattern. In this case, a plurality of weft insertion threads 51c are disposed throughout the entire first to fourth warps W1 to W7.

The warp knit fabric member 51 has a structure in which it is difficult to expand and contract in the longitudinal direction of the zipper by the crochet line 51a disposed in each of the warps. Therefore, similarly to the case where the braided chain member 14 is used as the fastener element, even if the fastener chain as the constituent member of the fastener string is removed, the fastener element 12 can be stably held by the warp knitted fabric member 51. Installation spacing.

Further, when a chain member including a nonwoven fabric or a film member 52 made of a synthetic resin shown in Fig. 12 is used as the fastener element, the braided link member 14 is also used. Similarly, in the case where the warp-knitted fabric member 51 of FIG. 11 is a fastener element, it has a structure which is difficult to expand and contract in the longitudinal direction of the slide fastener, and therefore, the fastener element can be stably held without using a fastener chain cloth. 12 installation spacing.

Further, as the material of the film member 52, for example, a thermoplastic resin such as polyester or nylon which is hard to be elastically deformed can be selected. Further, the film thickness of the film member 52 can be arbitrarily changed according to the size of the fastener element 12. For example, in order to provide the fastener chain 10 with moderate rigidity and flexibility, it is preferably set to 0.05 mm or more and 0.30 mm or less. It is 0.15 mm or more and 0.20 mm or less.

Further, in the present invention, the film member 52 made of synthetic resin is inserted into the upper and lower leg portions 12b and 12c of the fastener element 12 in a straight state along the longitudinal direction of the slide fastener, and thereafter, the sewing machine for sewing the fastener element is used. When the sewing machine needle is lifted and lowered and the fastener element 12 is sewn to the film member 52, the sewing machine needle pierces the film member 52.

Therefore, as shown in Fig. 12, a plurality of through holes 52a through which the sewing machine thread (needle thread) is inserted are formed in the film member 52. At the same time, when the sewing machine needle penetrates the film member 52 in the front-back direction, the film member 52 receives the stress from the sewing machine needle or receives the frictional force, whereby the film member 52 is deformed to face the longitudinal direction of the chain zipper. The direction is undulating (蜿蜒 shape). The film member 52 has a undulating shape (蜿蜒 shape) as a whole, but is formed linearly between the through holes 52a in the longitudinal direction of the zipper. Therefore, the film member 52 has a structure that is difficult to expand and contract in the longitudinal direction of the zipper.

Further, since the film member 52 has a wavy shape in the longitudinal direction of the zipper, it is possible to suppress the chain 10 of the zipperless fastener from being inserted between the lower leg portions 12b and 12c of the fastener element 12 by the film member 52. The flexibility of the zipper length direction is lowered.
