Description

Chain belt, zipper and items with zipper

The present invention relates to a chain belt in which a plurality of continuous fastener elements are stitched to a fastener element, a zipper having the chain, and a zipper-attached article having the zipper.

The zipper is often used as an opening and closing member for articles such as clothing materials, daily sundries, 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 has a pair of chain rows of fastener elements and a slider slidably disposed along the chain rows of the fastener fabric.

Further, as one of the representative examples of the fastener tape, there is known a fastener tape having a continuous fastener element which is formed into a coil shape or a zigzag shape by, for example, a thermoplastic resin monofilament. And a plurality of meshing heads are connected without interruption. The chain belt is formed by fixing a continuous fastener element to a side edge portion (sprocket mounting portion) of the fastener string by sewing with a suture, thereby forming a fastener element row.

For example, a continuous zipper sprocket which is formed into a zigzag shape generally has an engaging head portion which is disposed along the thickness direction of the zipper, and an upper leg portion and a lower leg portion which are self-engaging the upper and lower ends of the head portion. The zipper is extended in the width direction; and the connecting portion is alternately coupled to the end portions of the upper leg portion and the lower leg portion in the longitudinal direction of the zipper.

The zigzag continuous zipper fastener inserts the zipper chain cloth from the side of the connecting portion to the upper leg portion and the lower leg portion, and the upper leg portion and the lower leg portion are sewn together and fixed to the zipper chain cloth by the suture. This forms a chain belt.

Further, the fastener tapes obtained in the above-described manner are combined in a group of two, and further, the slide fasteners are attached to the fastener element rows formed by the continuous fastener elements of the fastener tape, thereby manufacturing the slide fastener. Further, the zipper is attached to the zipper-attached article by sewing a zipper chain cloth of each of the fastener tapes to a zipper-attached article such as clothes.

On the other hand, Japanese Patent Publication No. Sho 36-3037 (Patent Document 1) discloses a chain belt 80 as shown in Figs. 16 and 17, which has a shape in which the monofilament 81 is formed in a zigzag shape. A continuous zipper element 85.

In the chain belt 80 of Patent Document 1, the monofilament 81 is bent in a substantially S-shape so that the right and left inverting portions 82 are folded back, and the left and right inverting portions 82 of the formed monofilament 81 are formed. The inner portions are sewn and fixed to the two support members 83 formed by the first sutures 84, respectively.

Then, the substantially S-shaped monofilament 81 that is sewn and fixed to the support member 83 is bent in a U shape so that the two support members 83 are placed close to each other in a straight portion disposed between the right and left inverting portions 82. And the central portion of the straight portion is flattened to form a bulging portion 86 that bulges toward the longitudinal direction of the zipper.

Thereby, continuous fastener elements 85 are produced. Further, the support member 83 of the fixed fastener element 85 is sewn and fixed to the fastener stringer 88 by the second suture 87, whereby the fastener tape 80 shown in Fig. 17 is obtained.

In Patent Document 1, it is explained that, by using the fastener tape 80 shown in FIG. 17, it is possible to achieve an equal interval between the respective fastener elements 85 when the fastener is used for a relatively long period of time, and to form the respective fastener elements. Part 85 has a small free length.

Patent Document 1: Japanese Patent Publication No. Sho 36-3037

In recent years, in various articles, particularly clothing, bags, shoes, and the like, the zipper attached thereto has been treated as an element of design, and it is required to improve the overall appearance quality of the article including the zipper. Further, in the related art, the zipper is generally attached to the article as the zipper-attached member in a straight line. However, in recent years, the zipper is attached to the zipper, for example, in a curved state, for example, in terms of convenience or design of the article. In the case where the zipper is mounted with a member.

In this regard, the conventional zipper having the fastener tape 80 described in Patent Document 1 is sewn and fixed to a zipper-mounted member (for example, a clothing material, etc.) by a fastener zipper to which a continuous fastener element is fixed. It is used for opening and closing. Therefore, in order to smoothly perform the sewing of the zipper and the zipper-mounted member by the sewing machine, it is necessary to ensure that the width of the fastener main body portion of the zipper chain cloth exposed to the outer side of the fastener fabric in the width direction of the fastener zipper is secured as a hem. To some extent wider.

However, when the zipper is attached to the zipper-mounted member in a state of, for example, being bent into a curved shape or the like, the main body portion of the zipper at the outer peripheral portion may be partially raised or trapped to a large extent, or, The zipper cloth on the inner peripheral side of the zipper that is bent into a curved shape produces a large wrinkle with a surface corrugation.

Therefore, it is difficult to sew the zipper-mounted member by the sewing machine, and in the article to which the zipper is attached, if the zipper is swelled or caught, or the surface is corrugated, the appearance of the article is also present. (Appearance quality) reduced.

Moreover, in order to eliminate such a problem, for example, it is conceivable to directly sew a continuous fastener element to a fabric such as a garment to be a fastener attached member without using a fastener chain cloth. In this case, the operation of sewing the continuous fastener element to the fabric is performed by, for example, the manufacturer side of the article (clothing) or the like, but the manufacturer side is engaged in the sewing of the continuous fastener element. It is difficult to appropriately align the position of the fastener element with respect to the cloth or to stably maintain the interval (mounting pitch) between the fastener elements of each of the fastener elements.

Moreover, in the case where the fastener element is directly sewn to the side edge portion (attached edge portion) of the cloth For example, when the fastener element is sewn in a state in which the end surface of the side edge portion of the cloth is exposed, there is a problem in that the yarn is generated at the side edge portion of the cloth during the opening and closing operation of the zipper. The engagement of the zipper elements or the slidability of the sliders adversely affects.

Further, as in recent years, articles such as clothes with zippers are produced in small quantities in small quantities. Accordingly, the fabric is also used in various thicknesses. For example, when the fastener element is directly sewn to the side edge of the fabric, if the thickness of the fabric is thickened according to the use or design of the article, the zipper is sewn to the fabric. The thickness of the fastener elements also becomes larger.

Therefore, when the slider slides, the fastener element is pressed against the lower wing of the slider, and the sliding resistance of the slider becomes large, which causes a problem that the sliding operation of the slider cannot be performed briskly. That is, the sliding property of the slider is lowered. Further, due to friction with the slider, a problem that the stitch of the fastener element is sewn to the cloth is easily broken is caused.

In order to eliminate such a problem, for example, it is conceivable to prepare a slider in which the interval between the upper and lower blades is set to be large, or to prepare a slider in which a plurality of upper and lower blades are spaced apart from each other.

However, in the case of the former, for example, when a continuous fastener element is directly sewn to a thinner fabric to form a zipper, the fastener element is easily formed in the sprocket guiding path of the slider when the slider slides. Shaking causes a disadvantage that the sliding property of the slider is lowered or the meshing of the fastener elements is deteriorated. On the other hand, in the case of the latter, it is necessary to prepare a plurality of sliders corresponding to the thickness of the cloth, so that the burden on the cost becomes large, and it is not economical.

The present invention has been made in view of the above-described problems, and a specific object thereof is to provide a zipper that can be lightened or reduced in cost, and can be mounted in an excellent appearance even in a state of being bent into a curved shape or the like, and regardless of the member to be mounted. The thickness of the (cloth) can be matched by one type of slider, and the chain which can smoothly slide the slider, the zipper with the chain, and the zipper-attached article having the zipper can be ensured.

In order to achieve the above object, the present invention provides a chain belt as a basic structure, which has a chain of fastener elements, the most important feature of which is a plurality of fastener elements having a continuous shape of the fastener element rows, and a strip-shaped sprocket supporting member disposed along the sprocket row and for suturing the zipper element, the zipper element having: an engaging head; an upper leg and a lower leg, wherein the sprocket supporting member is sandwiched And extending from the engaging head portion in the width direction of the zipper; and the connecting portion, wherein the upper leg portions and the lower leg portion adjacent to each other in the longitudinal direction of the zipper are alternately or continuously connected to each other; the sprocket supporting member has: a bent portion a folding portion that is bent between the upper leg portion and the lower leg portion; an upper leg supporting piece portion extending from the one end of the bending portion along the upper leg portion for suturing the upper leg portion; and a lower leg supporting piece portion It extends from the other end of the bent portion along the lower leg portion and sutures the lower leg portion.

Further, the connecting portion of the fastener element may have a length along the longitudinal direction of the zipper In the first and second connecting cord portions, the first and second connecting cord portions are connected between the upper leg portions and the lower leg portions of the respective fastener elements.

Further, in the invention, it is preferable that the element supporting member is formed of a belt-shaped member having a woven structure, a belt-shaped member having a warp-knitted structure, a belt-shaped member including a nonwoven fabric, or a film member made of a synthetic resin. .

The zipper according to the present invention includes the zipper having the above-described fastener tape and the slider attached to the sprocket row of the fastener tape, and the main feature is that the zipper is supported by the sprocket supporting member. The upper leg supporting piece portion and the lower leg supporting piece portion are sandwiched by the attached edge portion of the zipper-attached member and fixed to the attached edge portion.

Further, in the slide fastener of the present invention, preferably, the fastener tape is fixed to the attached edge portion of the fastener attached member by a secondary stitch, and the secondary stitch is formed by the upper leg portion The first primary suture stitched to the upper leg supporting piece portion and the second primary suture stitching the lower leg portion to the lower leg supporting piece portion are formed by different lines.

Further, according to the present invention, there is provided a zipper-attached article, characterized in that a zipper having the above-described configuration is disposed on the attached rim portion of the zipper-attached member.

The chain belt provided by the present invention has: a plurality of continuous fastener elements having a meshing head, an upper leg portion, a lower leg portion, and a joint portion; and a belt-shaped fastener support member which is bent into The half state is disposed between the upper leg portion and the lower leg portion along the longitudinal direction of the zipper.

Further, the element supporting member has a bent portion which is bent in a substantially U shape toward the meshing head portion between the leg portion and the lower leg portion of the fastener element, and an upper leg supporting piece portion which is self-bending portion One end extends along the upper leg and is used to suture the upper leg portion; and a lower leg support piece portion extends from the other end of the bent portion along the lower leg portion for suturing the lower leg portion. In this case, it is preferable that the sprocket support member has a structure in which it is difficult to expand and contract in the longitudinal direction of the zipper.

In the chain belt of the present invention, since the leg portion and the lower leg portion of the fastener element are sewn to the element supporting member, the interval between the fastener elements (mounting pitch) can be stabilized by the element fixing member. The ground is kept at a fixed size.

Further, the fastener element supporting member of the present invention does not need to be wider than the portion of the fastener element which is exposed to the outer side of the fastener element as in the case of the conventional fastener chain, thereby ensuring a reduction in weight and cost of the slide fastener. Furthermore, in the present invention, the sprocket support member may have a portion exposed to the outside of the zipper element, and may also have a different purpose from the previous sipe of the zipper chain (for example, as follows) The purpose of protecting the zipper-attached member from the flange portion of the slider is to use the portion of the sprocket support member exposed to the outside of the fastener element.

Further, in the chain belt of the present invention, since it is not necessary to ensure that the element supporting member is exposed to the outside of the fastener element, the chain can be stably attached to the zipper in a state of being bent or curved. The component is installed. Further, even if the fastener tape is attached to the zipper-attached member in a state of being bent, it is difficult to cause swells or sag, or wrinkles on the surface of the sprocket support member, so that the appearance of the zipper-attached article can be obtained (appearance Quality) improvement.

Further, in the fastener tape according to the present invention, the accommodating portion is provided to sandwich the attached edge portion (side edge portion) of the zipper-attached member and is housed in the upper support piece and the lower leg of the sprocket support member. Support between the pieces. Therefore, when the chain belt of the present invention is sewn to the rim portion of the zipper-attached member with the rim portion of the zipper-attached member attached to the accommodating portion between the upper leg supporting piece portion and the lower leg supporting piece portion, The position of the mounted edge portion is restricted by the sprocket supporting member so that the mounted rim portion does not excessively approach the engaging head portion, whereby the zipper element can be appropriately positioned with respect to the mounted rim portion of the zipper-mounted member The alignment is such that the chain strap can be stably mounted at a specific position of the zipper-mounted member.

Further, when the fastener tape of the present invention is attached to the attached edge portion of the zipper-attached member, the side end surface of the attached rim portion of the zipper-mounted member is bent by the sprocket supporting member The way the department is encased is protected. Therefore, when the slider is attached to the element row of the fastener tape to form a slide fastener, even if the slider is slid and the slide fastener is opened and closed, the side of the attached edge portion protected by the bent portion can be provided. It is difficult for the end face to generate the loose yarn, so that various previous problems caused by the loose yarn can be eliminated.

Further, the fastener tape of the present invention is formed such that the thickness of the accommodating portion of the zipper-attached member of the fastener tape is based on the thickness of the rim portion of the zipper-mounted member, and the zipper-tooth is centered on the engaging head. Increase or decrease by elastic deformation. Therefore, although the interval between the leg portion and the lower leg portion of the fastener element is changed depending on the thickness of the attached edge portion of the zipper-attached member, regardless of the thickness of the attached rim portion of the zipper-mounted member, The size (height size) of the upper and lower directions of the engaging head of the fastener element is stably maintained within a specific range.

Further, the thickness of the attached edge portion of the zipper-mounted member is thin or thick, and the height of the engaging head of the fastener element is stabilized, for example, having an upper boss portion and a lower boss portion as described below. When a sliding member is slidably mounted on the element row of the chain belt of the present invention, the engaging head can be stably guided between the boss portion and the lower boss portion of the sliding member, and the guiding portion is guided by the guiding member It is difficult to cause the slider to shake when it slides.

Moreover, by guiding the engaging head of the zipper element when the sliding member slides, the foot and the lower leg of the zipper element are not like the zipper as before, and the upper and lower wings of the sliding element. Since the sliding contact is made, for example, regardless of the height dimension between the leg portion and the lower leg portion of the fastener element, the interval between the upper wing plate and the lower wing plate of the slider can be set to be somewhat larger.

Therefore, when the fastener tape is attached to the attached edge portion of the fastener attached member, even if the attached edge portion of the fastener attached member is thick, the height dimension between the leg portion and the lower leg portion of the fastener element is relatively When the slider is slid, the foot and the lower leg of the fastener element can be prevented from being pressed against the upper and lower flaps of the slider, so that the slider can be stably and smoothly slid smoothly. Also, the zipper element is sewn to the stitch of the sprocket support member (one time seam The stitches (secondary stitches) which are sewn to the attached edge portion of the zipper-mounted member are also difficult to rub with the sliding member, so that the stitches can be eliminated from the friction with the sliding member. The bad situation of cutting off.

In the chain belt of the present invention, the upper leg supporting piece portion and the lower leg supporting piece portion are formed in a zipper width direction in a region in which the leg portion and the lower leg portion are formed in the fastener element, and are formed into a zipper. The foot and the lower leg are shorter on the element. Thereby, the weight of the zipper or the cost reduction can be achieved. In addition, when the fastener tape is attached to the fastener attached member in a state in which the fastener tape is bent in a curved shape or the like, wrinkles such as surface corrugations are not generated in the fastener element supporting member, and the attachment of the fastener tape can be stably performed.

Further, in the chain belt of the present invention, the element supporting member may have an extension portion extending from the upper leg supporting piece portion and the lower leg supporting piece portion beyond the upper leg portion and the lower leg portion in the zipper width direction. Out.

Thereby, it is possible to prevent the flange portion and the lower flange portion of the slider from directly contacting the zipper-mounted member when the slider slides, thereby protecting the zipper-attached member from friction with the slider.

Further, in the chain belt of the present invention, the upper leg portion is sewn to the upper leg support piece portion by the first primary suture, and the upper leg support piece portion is sutured to the upper portion of the first suture line. Both sides extend along the upper leg. Further, the lower leg portion is sewn to the lower leg support piece portion by the second primary suture, and the lower leg support piece portion extends along the lower leg portion on both sides of the suture portion of the leg portion below the second primary suture.

In other words, in the present invention, the upper leg portion is sewn to the suture portion (the position of the sewn portion) of the first primary suture portion of the upper leg support piece portion and the bent portion of the element support member, and the lower leg portion is sewn A predetermined interval is provided between the stitching portion (the position of the sewing portion) of the second primary stitch that is sewn to the lower leg supporting piece portion and the bent portion of the element supporting member.

The sprocket support member upper leg supporting piece and the lower leg supporting piece portion are in a positional relationship with the first and second primary suture stitching positions as described above, whereby the upper leg portion and the lower leg portion can be respectively The primary suture is firmly and stably sewn to a specific position of the leg support piece and the lower leg support piece on the element support member. Further, when the fastener tape is sewn and fixed to the attached edge portion of the zipper-mounted member by the secondary suture, the positional alignment of the fastener element can be stabilized, and the fixation of the secondary suture can be made firm.

Further, the present invention is preferably applied to a fastener tape having a fastener element in which a monofilament is formed into a zigzag shape. In this case, the distance between the leg portion and the lower leg portion of the upper and lower leg portions of the fastener element is gradually increased from the meshing head side toward the end portion of the coupling portion side, relative to the thickness direction of the zipper. The orthogonal faces are inclined. Thereby, even if the attached edge portion of the zipper-attached member has various thicknesses, the attached rim of the zipper-attached member can be stably inserted between the leg portion and the lower leg portion of the fastener element, and The upper leg portion and the lower leg portion are firmly sewn and fixed to the specific position corresponding to the thickness dimension of the attached edge portion by the secondary suture.

Further, in the present invention, the connecting portion of the fastener element has the first and second connecting cord portions arranged along the longitudinal direction of the slide fastener, and the first and second connecting cord portions are preferably applied to each of the fastener elements. The chain belt of the form in which the foot portion and the lower leg portion are continuously connected, for example, is particularly preferably applied to a chain belt having the following fastener elements, that is, the engaging head portion, the upper leg portion, and the lower leg portion are used The synthetic resin is injection molded so that the first and second connecting strands are inserted into the end portions of the upper leg portion and the lower leg portion, respectively.

Further, in the fastener tape of the present invention, as the fastener element, a belt-shaped member having a woven structure, a belt-shaped member having a warp-knitted structure, a belt-shaped member including a nonwoven fabric, or a synthetic resin can be used. Membrane member. By forming the element supporting member with such a belt-shaped member or a film member, it is possible to make the element supporting member difficult to expand and contract in the longitudinal direction of the zipper with a simple structure, whereby the fastener element in the chain belt can be stably held. Installation spacing. Moreover, in the case of such a belt-shaped member or a film member, the fastener element is used to lower the fastener element, for example, using a sewing machine. When the portion is sewn to the belt member or the film member, the sewing machine needle can be stably pierced by the belt member or the film member, and the sewing operation can be smoothly performed.

Further, the zipper and the zipper-attached article provided by the present invention include the chain belt having the above-described configuration, and a slider attached to the fastener element row of the chain belt, the chain belt being supported by the upper support piece of the sprocket support member and The lower leg supporting piece portion is fixed to the mounted edge portion by sandwiching the attached rim portion of the zipper-attached member.

Example 1

Fig. 1 is a perspective view schematically showing a chain belt of the first embodiment, and Figs. 2 and 3 are a plan view and a cross-sectional view of the chain belt. In addition, in FIG. 1, the relationship of a fastener element and a fastener element is shown easily, and the illustration of the one stitch is abbreviate|omitted, and the structure of the double-chain slit is simplified in FIG. 2 and FIG. Indicates a stitch.

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

The left-right direction refers to the width direction of the zipper of the chain belt and the zipper, and is, for example, a direction parallel to the front surface and the back surface of the zipper-attached member (cloth) of the stitching chain belt and orthogonal to the longitudinal direction of the chain fabric. 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 orthogonal to the front surface and the back surface of the zipper-attached member. In particular, the direction in which the slider of the slider is disposed on the fastener element is set to the upper side, and the direction of the opposite side is set to the lower side.

As shown in FIG. 1 to FIG. 3, the chain belt 1 of the first embodiment has a plurality of fastener elements 10 which are formed in a zigzag pattern and which are formed in a zigzag pattern, and along the longitudinal direction of the fastener element 11 in the longitudinal direction (front and rear direction). The extended strip-shaped sprocket support member 20 is formed by sewing the fastener element 10 to the sprocket support member 20 with a primary suture 51.

The fastener element 10 is formed in a continuous shape by forming a monofilament made of a thermoplastic resin such as polyamide or polyester into a zigzag shape, and has an engaging head portion 12 and an upper leg portion (also referred to as a first leg portion). 13 and a lower leg portion (also referred to as a second leg portion) 14 which extends from the meshing head portion 12 in the width direction of the zipper; and a joint portion 15 which is adjacent to the fastener element 10 adjacent to the zipper length direction The leg portions 13 and the lower leg portions 14 are alternately coupled to each other.

The engaging head portion 12 has a specific height dimension A in the up-and-down direction, and has a bulging portion 12a that bulges in the front-rear direction in the center portion in the up-and-down direction. The upper end (or upper surface) to the lower end (or lower surface) of the self-engaging head 12 which becomes the height dimension A of the engaging head portion 12 is sized to form the zipper 5 using the chain belt 1 of the first embodiment. At this time, it is set to be smaller than the interval between the boss portion 48 and the lower boss portion 49 of the slider 34 disposed on the zipper 5 (see FIG. 7).

In this case, as shown in FIG. 3, the height dimension A of the engaging head portion 12 is defined as the dimension in the upper and lower directions of the inner peripheral surface of the engaging head portion 12 in the width direction of the zipper. Further, the height dimension A of the engaging head portion 12 is preferably set to prevent the left and right fastener elements 10 from swaying in the vertical direction in the element guide path of the slider 40, for example, the upper boss portion 48. And the interval between the lower boss portions 49 is 85% or more. In turn, by the meshing head The portion 12 has a specific height dimension A, so that when the fastener string 5 is formed using the fastener tape 1 of the first embodiment, the left and right fastener elements 10 can be stably and appropriately engaged.

The upper leg portion 13 and the lower leg portion 14 are extended from the meshing head portion 12 toward the zipper width direction in a plan view (or a bottom view), and are spaced apart from the upper leg portion 13 and the lower leg portion 14 in the front view (or rear view). The end portion (outer end portion) toward the connecting portion 15 side is gradually increased in a direction that is inclined with respect to a plane orthogonal to the thickness direction of the zipper.

In this case, when the fastener tape 1 is attached to the zipper-attached member (cloth 8), the upper leg portion 13 and the lower leg portion 14 are fixed to the zipper-mounted member so as to sandwich the zipper-attached member. The inclination angles of the upper leg portion 13 and the lower leg portion 14 vary depending on the thickness of the zipper-mounted member.

The connecting portion 15 is disposed in the longitudinal direction of the zipper in such a manner that the upper leg portion 13 of the fastener element 10 is coupled to the upper leg portion 13 of the fastener element 10 adjacent to one side of the fastener element 10 in the front-rear direction. And the lower leg portion 14 of the fastener element 10 is coupled to the lower leg portion 14 of the fastener element 10 adjacent to the other side of the fastener element 10 in the front-rear direction.

Further, the fastener element 10 is formed so as to be elastically deformable so as to increase or decrease the interval between the upper leg portion 13 and the lower leg portion 14 around the meshing head portion 12. Further, in the first embodiment, the fastener element 10 may be decorated by coloring or plating the fastener element 10 itself.

The sprocket support member 20 of the first embodiment is formed of a belt-like member having a woven structure, and is preferably formed of a belt-like member, that is, woven by a plurality of warp yarns and two single yarns and A plain weave fabric in which a weft yarn of one set is woven by a single layer weave, and has a structure in which expansion and contraction in the longitudinal direction of the zipper is suppressed and it is difficult to expand and contract.

Further, as the sprocket support member 20, in addition to the belt-like member woven into the plain weave structure, a belt-shaped member having a warp-knitted structure in which chain knitting yarns are arranged in each warp, and a belt including non-woven fabric may be used. A member, a film member made of a synthetic resin, or the like.

The sprocket support member 20 is disposed in a state of being bent in half in the longitudinal direction. The chain element 10 is disposed between the leg portion 13 and the lower leg portion 14, and the element supporting member 20 has a bent portion 21 which is bent in a U shape in a cross-sectional view; the upper leg supports the piece portion 22, one end portion of the bent portion 21 (which is an upper end portion on the upper leg portion 13 side in a state in which the element supporting member 20 is disposed between the upper leg portion 13 and the lower leg portion 14) extends along the upper leg portion 13 And the lower leg supporting piece portion 23, which is the other end portion of the bent portion 21 (the lower end portion of the upper leg portion 13 side is disposed in a state where the element supporting member 20 is disposed between the upper leg portion 13 and the lower leg portion 14) ) extends along the lower leg portion 14.

Further, the element supporting member 20 is disposed with respect to the fastener element 10 so that the bent portion 21 faces the meshing head portion 12 and the opening side faces the outer side in the width direction of the slider, and the upper leg support piece 22 and the lower leg are provided. Between the support piece portions 23, a accommodating portion 24 for attaching the edge portion 8a of the zipper-attached member (cloth 8) from the outer side end portion and the lower leg portion 14 of the upper leg portion 13 of the fastener element 10 is provided. Insert between the outer end portions and accommodate them. The accommodating portion 24 can be elastically deformed around the engaging head portion 12 by the fastener element 10 to increase or decrease the interval between the upper leg supporting piece portion 22 and the lower leg supporting piece portion 23.

In this case, the bent portion 21 of the element supporting member 20 is disposed opposite to the engaging head portion 12 at a position spaced apart from the engaging head portion 12 of the fastener element 10, and is engaged when the zipper 5 is formed. The engaging head portion 12 (particularly, the bulging portion 12a) of the zipper element 10 of the object side can enter between the bent portion 21 and the engaging head portion 12.

Further, on the upper support piece 22 of the element support member 20, the upper portion 13 of the fastener element 10 is sewn by the double chain stitch of the upper primary stitch (first primary stitch) 51, and The lower leg supporting piece portion 23 of the sprocket supporting member 20 is sewn with the lower leg portion 14 of the fastener element 10 by the double chain stitch of the lower primary stitch (second primary stitch) 51.

Further, in the first embodiment, the upper leg supporting piece portion 22 and the lower leg supporting piece portion 23 of the element supporting member 20 are traversed by the suture portion (primary sewn portion) of the primary suture 51 of the upper side and the lower side, respectively. The method extends along the left and right sides 13 or the lower leg portion 14 on the left and right sides of the suture portion of the primary suture 51. Therefore, the suture portion of the primary suture 51 of the upper side and the lower side (one seam The part is disposed apart from the bent portion 21 of the element supporting member 20, and is provided between the stitching portion of the upper suture 51 of the upper side and the lower side and the bent portion 21 of the element supporting member 20 The interval.

In this case, the looper thread of the primary suture 51 of the upper and lower double-strand stitches straddles the outer surface side of the upper leg portion 13 or the lower leg portion 14, and the stitching of the primary suture 51 is disposed on the sprocket. The inner peripheral surface side of the support member 20 is pierced between the mutually adjacent fastener element 10, and the loop support member 20 is interlaced with the looper thread passing through the outer surface side of the upper leg portion 13 or the lower leg portion 14.

Thereby, the primary suture 51 can suture and fix the upper leg portion 13 and the lower leg portion 14 to the element supporting member 20 so as to hold the upper leg portion 13 and the lower leg portion 14 of the fastener element 10, thereby zipper teeth The upper leg portion 13 and the lower leg portion 14 are firmly fixed and supported at a specific position of the element supporting member 20, and the mounting pitch of the fastener element 10 (in other words, the interval between the engaging heads 12) is kept constant. size.

Further, by using the double chain slit as the stitch form of the primary stitch 51, the strength of the stitch can be excellent, and even if the primary stitch 51 is cut in the middle, it is difficult to generate the loose yarn of the primary stitch 51. In particular, in the first embodiment, the stitching of the primary suture 51 is disposed so as to be concealed on the inner peripheral side of the fastener element 10, so that the needle thread is protected by the fastener element 10 and is difficult to be cut, thereby being more effective. Prevent the stitching of the suture 51 once.

Further, by sewing the fastener element 10 and the element supporting member 20 with the double chain stitch of the primary stitch 51, the fastener tape 1 can be manufactured with high productivity. Further, in the present invention, as the stitch form of the primary suture 51, a double chain slit such as a lock type stitch can be used.

Further, in the sprocket supporting member 20 of the first embodiment, the sprocket supporting member 20 is placed in the zipper width direction, and is disposed on the zipper element 10 above the leg portion 13 and the lower leg portion 14 in the zipper width direction. In the formation area. In other words, the upper leg supporting piece portion 22 and the lower leg supporting piece portion 23 of the element supporting member 20 are such that the outer leg supporting piece portion 22 and the lower leg supporting piece portion 23 have the outer side edges (the side opposite to the bent portion 21 side) The edge of the edge is in the direction of the width of the zipper The positions of the outer side edges of the leg portion 13 and the lower leg portion 14 of the fastener element 10 are disposed closer to the meshing head portion 12, and are formed shorter than the upper leg portion 13 and the lower leg portion 14.

Thereby, the element supporting member 20 is not exposed to the outer side of the fastener element 10, so that it is difficult to see the element supporting member 20 when forming the zipper 5 and the article (clothing) with the zipper 5 as described below. It can improve its appearance (appearance quality).

Next, a method of manufacturing the above-described chain belt 1 of the first embodiment will be described.

First, a single monofilament made of a thermoplastic resin forming the fastener element 10 and a fastener element 20 having a strip shape elongated in the longitudinal direction are prepared. At this time, the element supporting member 20 has a specific chain width dimension depending on the size of the fastener element 10 to be formed.

Then, the bending process is performed in such a manner that the prepared monofilament is bent in a zigzag manner in a substantially S-shape as shown in FIG. 4 in a longitudinal direction (front-rear direction). Folded to form a left and right fold back. At the same time, the press working is performed by flattening the central portion of the straight portion formed between the left and right folded portions in the zigzag form in the thickness direction (up and down direction) to drum in the longitudinal direction. Out.

Thereby, the primary element forming body 10a is formed. At this time, the primary sprocket molded body 10a has the form in which the leg portion 13 and the lower leg portion 14 of the fastener element 10 are opened in a planar manner toward the left and right with the meshing head portion 12 as a center, and the folded portion of the primary sprocket molded body 10a becomes The spur portion formed by the press working of the connecting portion 15 of the fastener element 10 serves as the bulging portion 12a of the engaging head portion 12.

Then, the sewing process is performed by laminating (mounting) the element supporting member 20 on one surface of the formed primary element forming body 10a (the surface on the inner peripheral side in the fastener element 10), and using the chain. In the sewn sewing machine, the primary element forming body 10a is sewn and fixed to the element supporting member 20 by the double chain slit of the primary suture 51.

At this time, the first primary suture 51 is used to sew the folded portion (for example, the folded portion on the left side) of the primary element forming body 10a and the bulging portion 12a in the front-rear direction, and The primary suture 51 sews the other fold-back portion (for example, the folded portion on the right side) and the bulging portion 12a in the front-rear direction. Thereby, the primary sprocket molded body 10a is sewn to the sprocket support member 20 by the two left and right primary sew parts (primary sutures) formed by the primary suture 51 (see FIGS. 4 and 5). At this time, the primary sewn portion formed by the left and right primary sutures 51 is formed at a position substantially in the middle of the folded-back portion and the bulging portion 12a in the width direction.

Further, in this case, when the fastener tape 1 is manufactured, the bent portion 21 of the fastener element 20 is separated from the engaging head portion 12 of the fastener element 10 as described above, so that it is preferably, for example, one facing The sprocket support member 20 applies the above-described sewing process while applying a specific tension such that the flat sprocket support member 20 is stretched toward the outside in the width direction (left-right direction).

Further, for example, a bending process may be performed in which the primary element forming body 10a is bent in a substantially V shape so that the meshing head portion 12 is slightly spaced apart from the element supporting member 20, and the chain is formed. The tooth support member 20 is placed in the state of the substantially V-shaped primary element forming body 10a, and the above-described sewing process is performed.

Thereafter, the bending process of bending the primary element forming body 10a stitched to the element supporting member 20 is performed. In the bending process, the central portion of the straight portion extending in the width direction of the primary sprocket molded body 10a (the region which becomes the engaging head portion 12) is centered on the left and right sides of the straight portion (becomes The portion of the upper leg portion 13 and the lower leg portion 14 is formed by bending the primary element forming body 10a into a substantially U shape so that the element supporting member 20 is folded in the direction of the inner side. Thereby, the sprocket support member 20 to which the sprocket molded body 10a is stitched once is also bent in the same manner as the primary sprocket molded body 10a, thereby manufacturing the fastener tape 1 of the first embodiment shown in FIGS. 1 to 3. .

In the fastener tape 1 of the first embodiment manufactured in this manner, since the fastener element 10 is sewn and fixed to the element supporting member 20, the mounting pitch of the fastener element 10 (the engaging head 12 in the longitudinal direction of the zipper) The interval between them is stably maintained at a fixed size.

Further, with regard to the element supporting member 20, since it is not necessary to use a portion which is exposed to the outside of the fastener element 10 as a seam as in the case of the conventional so-called fastener chain cloth, it is not necessary to be wide, so Further, the weight of the slide fastener 5 formed by using the fastener tape 1 of the first embodiment can be reduced, or the manufacturing cost can be kept low.

Next, a method of forming the slide fastener 5 by attaching the fastener tape 1 of the first embodiment as described above to the fabric 8 as the garment of the zipper-attached article will be described.

Further, in the present invention, as a representative of the zipper-attached member to which the fastener tape 1 is attached, a cloth 8 of clothes (clothing material) is attached, and the chain tape 1 is attached to the front piece of the clothes. The opening and closing portion of the opening portion or the opening and closing portion (opening peripheral portion) of the pocket portion of the chest piece and the abdomen of the front piece is formed to form the slide fastener 5.

In this case, in the opening and closing portion of the clothes, the side edges of the left and right fabrics 8 are arranged to be opposed to each other by the opening and closing of the slide fastener 5, and the left and right side edges of the opposite sides are respectively The installed edge portion 8a of the fastener tape 1 is attached. Further, the article (product) in which the fastener tape 5 is attached and the zipper 5 is attached is not limited to clothes, and includes household goods such as shoes, bags, and sheets, industrial materials, and the like, automobiles, trains, airplanes, and the like. Various items such as various types of seats.

In the case of forming the zipper 5 of the first embodiment, first, the cloth 8 of the garment to be the zipper-attached member is inserted between the leg portion 13 and the lower leg portion 14 of the fastener element 10 in the fastener tape 1, and inserted. The sprocket support member 20 is formed in the accommodating portion 24 between the upper leg support piece portion 22 and the lower leg support piece portion 23.

At this time, as the cloth 8, it is preferable to use a thickness having a thickness equal to or less than the size of the height between the outer side edge of the leg supporting piece portion 22 and the outer side edge of the lower leg supporting piece portion 23 of the element supporting member 20. Furthermore, in the first embodiment, the case where the thickness of the cloth 8 is thicker than the height dimension of the element supporting member 20 or less (for example, thicker than the cloth 9 of the following modification) will be described.

In the sprocket support member 20 of the first embodiment, the bent portion 21 is bent in a substantially U-shape toward the meshing head portion 12, and is disposed between the leg portion 13 and the lower leg portion 14 of the fastener element 10. Therefore, the cloth 8 inserted into the accommodating portion 24 can be prevented from being excessively close to the shank by the sprocket supporting member 20. The head portion 12 is closed so that the attached edge portion 8a of the cloth 8 can be held at a specific position of the side edge end of the attached edge portion 8a to abut against the element supporting member 20.

Thereby, the positional alignment of the fastener element 10 with respect to the to-be-attached edge part 8a of the cloth 8 can be suitably performed, and the left and right fastener element 10 can be suitably and stably meshed at the time of formation of the slide fastener 5. At the same time, since the attached edge portion 8a of the cloth 8 is wrapped in the element supporting member 20, the mounted edge portion 8a (especially the side of the mounted edge portion 8a) can be covered by the element supporting member 20 End face).

Next, in a state in which the cloth 8 is inserted into the accommodating portion 24 of the fastener tape 1, the chain portion 1 upper leg portion 13 and the lower leg portion 14 and the sprocket support member 20 are attached by the chain sewing machine. The upper leg supporting piece portion 22 and the lower leg supporting piece portion 23 straddle the entire longitudinal direction of the zipper, and are simultaneously sewn and fixed to the mounted edge of the cloth 8 inserted into the accommodating portion 24 by the locking stitching of the secondary suture 52. Part 8a. The secondary suture 52 is a line different from the first primary suture 51 and the second primary suture 51.

In this case, in order to securely suture the fastener tape 1 to the fabric 8, the secondary sewing portion (secondary stitch) formed by the lock stitching of the secondary stitch 52 is preferably in the width direction of the zipper. It is disposed between the sewing position of the primary suture 51 and the position of the outer edge of the leg portion 13 and the lower leg portion 14 above the fastener element 10.

Further, in the present invention, the stitch form in which the fastener tape 1 is sewn to the secondary stitch 52 of the cloth 8 is not particularly limited, and can be arbitrarily changed, but by using the lock type stitch as the secondary stitch 52. In the form of stitches, the chain tape 1 and the cloth 8 can be smoothly and stably stitched, and the stitches of the secondary stitch 52 can be obtained, which is difficult to unravel and has excellent strength.

Further, in the first embodiment, the fastener tape 1 is fixed to the fabric 8 by sewing. However, in the present invention, in addition to suturing, for example, welding by ultrasonic welding or the like, or adhesion of an adhesive may be employed. The element support member 20 is fixed to the cloth 8, and the chain 1 is attached to the cloth 8.

In the first embodiment, the sewing is performed by using the sewing machine for the chain sewing as described above. The processing is performed, and as shown in FIG. 6, the leg portion 13 and the lower leg portion 14 of the fastener element 10 in the fastener tape 1 are fastened by the secondary suture 52, and the attached edge portion 8a of the cloth 8 is attached. The fastener support member 20 is sandwiched between the leg support piece portion 22 and the lower leg support piece portion 23, and the fastener tape 1 is sewn and fixed to the cloth 8.

Then, as described above, the chain belt 1 of the first embodiment is sewn to the cloth 8 of the clothes by the secondary stitches 52, and the pair of left and right attached edge portions 8a are disposed opposite to the opening and closing portions. Thereafter, the slider 40 is attached to the element row 11 of the left and right chain belts 1. Thereafter, a first stop and a second stop (not shown) are formed so as to be adjacent to the front end and the rear end of the element row 11. Thereby, the zipper 5 of the first embodiment is formed, and the article (clothing) to which the zipper 5 is attached is manufactured.

Here, the slider 40 used for the slide fastener 5 of the first embodiment has a slider main body 41 and a pull tab 42 attached to the slider main body 41 as shown in FIG. Further, the slider main body 41 has an upper blade 43 and a lower blade 44 which are disposed apart from and parallel with the upper blade 43. The guide post 45 has the front end of the upper and lower blades 43, 44 (introduction side) The upper flange portion 46 is vertically disposed from the left and right side edge portions of the upper blade 43 toward the lower blade 44; the lower flange portion 47 faces upward from the left and right side edges of the lower blade 44 The wing plate 43 is erected; the upper boss portion 48 (also referred to as the upper middle partition portion) is formed on the inner surface of the upper wing plate 43 (the sprocket guiding surface); the lower boss portion 49 (also referred to as the lower middle portion) The portion is formed on the inner surface of the lower blade 44 (the sprocket guiding surface); and the tab mounting portion 50 is disposed on the upper surface of the upper blade 43.

The upper and lower boss portions 48, 49 of the slider main body 41 are formed at a central portion in the width direction of the inner surfaces of the upper and lower blades 43, 44, and are formed with a specific height dimension, and between the upper and lower boss portions 48, 49. The interval in the up and down direction is set to a specific size corresponding to the height dimension A of the meshing head portion 12 of the fastener tape 1.

Further, at the front end portion of the slider main body 41, left and right introduction ports are formed, and the guide post 45 is interposed therebetween, and an engagement opening is formed at the rear end portion of the slider main body 41. Further, between the upper and lower blades 43, 44, a substantially Y-shaped sprocket guide path is formed so that the left and right introduction ports communicate with the engagement opening.

The first stop of the zipper 5 is attached to the cloth 8 adjacent to the front end of the left and right element rows 11, so that the slider 40 does not fall off from the front end side of the element row 11. Further, the second stopper is attached to the cloth 8 so as to be adjacent to the rear end of the left and right element rows 11 and to straddle the left and right chain rows 11, so that the slider 40 does not fall off from the rear end side of the element row 11. .

Further, in the present invention, the method of attaching the first and second stoppers to the fabric 8 is not particularly limited. For example, the first and second stoppers may be fixed to the fabric 8 by welding or welding, and The first and second stoppers made of metal can be plastically deformed by press working or the like to be fixed to the cloth 8.

Further, in the present invention, the separable insert may be provided adjacent to the rear end of the element row 11 instead of the second stopper. Further, for example, the end portion of the element row 11 can be formed by pressing the end portion of the element row 11 and pressing it, or the end portion of the element row 11 can be sewn in a traversing manner, whereby the second stopper can be formed.

Furthermore, in the first embodiment, after the pair of fastener tapes 1 are sewn to the fabric 8, the slider 40 is attached to the fastener element row 11 of the fastener tape 1, and the first stopper and the second stopper are mounted. On cloth 8. However, in the present invention, after the slider 40 is attached to the element row 11 of the pair of chain belts 1, for example, the chain 1 is sewn to the cloth 8 by the locking stitch of the secondary stitch 52. .

The garment having the zipper 5 of the first embodiment obtained in the above-described manner is a chain belt 1 of the first embodiment in which the fastener element 20 bent in a U shape is disposed between the upper and lower leg portions 13 and 14. Since the zipper 5 is formed, the weight reduction or cost reduction of the zipper 5 can be easily achieved.

Further, even in the case where the chain belt 1 is attached to the garment in a curved shape or the like, for example, in the fastener tape 1 of the first embodiment, the fastener element 20 is not exposed to the fastener element 10 . Further, the outer side is not embossed or entangled in the zipper chain which is a problem in the prior zipper 5, or wrinkles such as corrugations on the surface, so that the appearance quality of the product can be improved.

Further, in the slide fastener 5 of the first embodiment, the side end surface of the cloth 8 to be attached to the edge portion 8a is chained. The tooth support member 20 is wrapped so that the attached edge portion 8a can be protected by the element support member 20 without performing end treatment such as folding the attached edge portion 8a toward the cloth 8 or the like.

As a result, even if the slide member 40 is slid and the opening and closing operation of the slide fastener 5 is repeated, the side end surface of the attached edge portion 8a is less likely to be loosened, and even the side end surface of the attached edge portion 8a is loosened. It is also effective to prevent the sliding property of the slider 40 from being lowered.

Further, in the zipper 5 of the first embodiment, the attached edge portion 8a of the cloth 8 is housed in the sprocket support member 20 which is bent into a U-shape between the upper and lower leg portions 13 and 14, so that the cloth is attached When the mounted edge portion 8a of 8 is relatively thick as in the first embodiment, the interval (height size) between the upper and lower leg portions 13 and 14 is slightly enlarged by the attached edge portion 8a of the cloth 8, but meshed. The height dimension of the head portion 12 is stably maintained to a size within a specific range regardless of the thickness of the mounted edge portion 8a.

Therefore, when the zipper 5 is formed, as the slider 40, regardless of the thickness of the attached edge portion 8a of the cloth 8, the interval between the upper boss portion 48 and the lower boss portion 49 as shown in Fig. 7 can be used. One type of shared slider 40 is adapted to the height of the meshing head 12 of the zipper element 10. Therefore, it is not necessary to prepare a plurality of types of sliders having different intervals between the upper and lower flaps in accordance with the thickness of the attached edge portion 8a of the cloth 8, for example, the economical efficiency can be improved, and the manufacture of the article with the zipper 5 can be reduced. cost.

Further, in this case, when the left and right fastener elements 10 are inserted into the element guide path of the slider 40, as shown in Fig. 7, the upper and lower boss portions 48, 49 of the slider 40 restrict the engagement of the head portion 12. Movement in the up-and-down direction, and the upper and lower flange portions 46, 47 of the slider 40 oppose the outer side edges of the left and right upper and lower leg portions 13, 14, and restrict the movement of the fastener element 10 in the left-right direction, thereby enabling the zipper chain The position of the tooth 10 relative to the slider 40 is stable.

Therefore, the fastener element 10 can be smoothly and stably guided along the substantially Y-shaped sprocket guiding path of the slider 40, whereby the sprocket guiding path of the left and right zipper elements 10 on the slider 40 can be effectively prevented. The inner side is shaken, so that the meshing action or the separating action of the left and right fastener elements 10 can be stably performed.

Moreover, when the slider 40 slides, the engaging head portion 12 of the fastener element 10 is guided by the upper boss portion 48 and the lower boss portion 49 of the slider 40, so that the slider 40 and the lower flap of the slider 40 can be provided. The interval between the 44s is set to be somewhat larger.

Therefore, even if the height of the upper and lower leg portions 13 and 14 of the fastener element 10 is relatively large due to the thicker attachment edge portion 8a of the fabric 8, the slider can be prevented from being relatively large as in the first embodiment. When the 40 is slid, the upper and lower leg portions 13, 14 of the zipper element 10 are pressed against the upper and lower flaps 43, 44 of the slider 40, so that the slider 40 can be stably ensured to slide smoothly and smoothly. Further, it is also difficult to cause the fastener element 10 to be sewn to the primary suture 51 of the element supporting member 20 or the secondary suture 52 which sews the fastener tape 1 to the cloth 8 to rub against the slider 40. The primary and secondary sutures 51, 52 are severed due to friction with the slider 40.

Furthermore, in the above-described first embodiment, the case where the chain belt 1 is attached to the relatively thick cloth 8 has been described, but the chain belt 1 of the first embodiment is as long as the thickness of the cloth is in the chain belt 1. The fabric can be attached to the sprocket support member 20 at a level equal to or less than the height dimension between the outer side edge of the upper leg support piece portion 22 and the outer side edge of the lower leg support piece portion 23. Therefore, for example, in the case of the modification of the first embodiment shown in Figs. 8 and 9, the fastener tape 5 can be attached to the fabric 9 having a relatively small thickness to form the slide fastener 5a.

That is, the fastener tape 1 of this modification is the same as the fastener tape 1 of the above-described first embodiment, and the fastener tape 1 is attached to the fabric 8 having a thickness smaller than that of the first embodiment in the same manner as in the first embodiment. The thin cloth 9 is attached to the edge portion 9a to form a zipper 5a of a variation, and an article to which the zipper 5a is attached is manufactured. In this case, for the slider 40, the same shared slider 40 as in the first embodiment is used.

In the zipper 5a of the variation formed in this manner, since the fastener tape 1 is sewn to the fabric 9 having a relatively small thickness, the lower leg portions 13, 14 are sewn on the fastener element 10 of the fabric 9 by the secondary seam. The wire 52 is securely fastened. Thereby, although the height dimension from the upper surface of the upper leg portion 13 to the lower surface of the lower leg portion 14 becomes smaller than that of the first embodiment, the height dimension A of the engaging head portion 12 of the fastener element 10 is maintained to be The situation of Embodiment 1 is substantially the same size.

Therefore, when the left and right fastener elements 10 are inserted into the element guide path of the slider 40, as shown in FIG. 9, the upper and lower boss portions 48, 49 of the slider 40 restrict the movement of the upper and lower sides of the engaging head 12. Further, the upper and lower flange portions 46, 47 of the slider 40 oppose the outer side edges of the left and right upper and lower leg portions 13, 14, and restrict the movement of the fastener element 10 in the left-right direction, whereby the fastener element 10 can be made relatively slippery. The position of the piece 40 is stable.

Therefore, the fastener element 10 can be smoothly and stably guided along the substantially Y-shaped sprocket guiding path of the slider 40, whereby the sprocket guiding path of the left and right zipper elements 10 on the slider 40 can be effectively prevented. The inner side is shaken, so that the meshing action or the separating action of the left and right fastener elements 10 can be stably performed.

Further, in the zipper 5a according to the modification, as in the case of the first embodiment, when the slider 40 slides, the upper leg portion 13 and the lower leg portion 14 of the fastener element 10 and the upper plate of the slider 40 can be prevented. 43 and the lower wing 44 are crimped, so that the slider 40 can be stably ensured to slide lightly and smoothly. Further, the primary suture 51 or the secondary suture 52 is also difficult to rub against the slider 40, so that it is difficult to cause the primary and secondary sutures 51, 52 to be severed due to friction with the slider 40.
