Stringer without fastener tape, slide fastener without fastener tape, and article with slide fastener

In the present invention, a continuous fastener element formed from a monofilament is fixed to a narrow element fixing member, and a step portion is provided on the lower leg portion of the fastener element so that the upper leg portion and the lower leg portion are provided between the upper surface and the lower leg portion. The fastener tape-less stringer in which the dimension in the vertical direction of the step portion is set to be smaller than the dimension on the meshing head side of the step portion, the slide fastener without the fastener tape having the stringer, and The present invention relates to an article with a slide fastener having the slide fastener.

Slide fasteners are often used as opening and closing devices for articles such as clothing, daily goods, industrial materials, and various seats such as automobiles, trains, and aircraft. A slide fastener used for an opening / closing part of various articles is generally a pair of fastener stringers in which an element row is formed on a tape side edge of a fastener tape, and a slider arranged to be slidable along the element row. Have

As a typical example of a fastener stringer, for example, a monofilament made of a thermoplastic resin is formed in a coil shape or a zigzag shape, and has a continuous fastener element in which a plurality of meshing heads are connected in a row. Fastener stringers are known. In this fastener stringer, continuous fastener elements are sewn and fixed to one side edge portion (element attachment portion) of a woven or knitted fastener tape with a sewing thread to form an element row.

As an example of a slide fastener in which an element row is formed by such continuous fastener elements, one described in, for example, Japanese Patent Application Laid-Open No. 2006-247279 (Patent Document 1) is known.

In the slide fastener 100 described in Patent Document 1, as shown in FIG. 11, a continuous fastener element 101 is sewn to an element attaching portion disposed on one side edge side of a fastener tape 102 by a sewing thread. A pair of stringers 103 and a slider 104 attached to the element row of the continuous fastener element 101. In this case, the fastener tape 102 has a wide tape main part and an element attachment part arranged on one side edge side (inner edge side) of the tape main part.

Further, when such a slide fastener 100 is sewn to an article such as a clothing article that is a fastener attaching member, the tape main portion of the fastener tape 102 (that is, the upper surface on which the continuous fastener element 101 is disposed on the stringer 103). When viewed from the side, it is sewn with a sewing machine in a state where the tape portion that extends to the outside of the continuous fastener element 101 and is exposed and the opening / closing portion (opening peripheral edge portion) that becomes the fastener attaching portion of the article are overlapped.

For example, Japanese Utility Model Publication No. 48-40088 (Patent Document 2) describes a slide fastener in which a recess is provided in a fastener element (element). In the slide fastener described in Patent Document 2, as shown in FIG. 12, a constricted space portion 302 is formed by providing a concave portion in the center in the width direction of the element turning portion 301, and the constricted space portion 302 is sandwiched therebetween. By forming the enormous space portion 303 located on the opposite side of the meshing portion 304, the core material can be held in the correct position in the element turning portion 301 and sewn to the tape.

Further, in the slide fastener described in Japanese Utility Model Laid-Open No. 50-95102 (Patent Document 3), as shown in FIG. 13, two wires 402 adjacent to a certain length by bending a single filament, It is molded into 402 'and bent into a U shape around the meshing portion 404 provided in the middle of each of the two wires 402, 402'. Further, in the slide fastener in which the upper and

lower legs

405 and 406 are formed, as shown in FIG. 14, the portion of the lower leg 406 opposite to the engagement portion 404 is bent so as to contact the upper leg 405, and the tape 408 An example of mounting on one side is shown.

JP 2006-247279 A Japanese Utility Model Publication No. 48-40088 Japanese Utility Model Publication No. 50-95102

In recent years, various articles, especially clothes such as clothing, daily necessaries such as clothing, shoes, etc., slide fasteners attached to them have been treated as one element of design, including slide fasteners. There is a need to improve the appearance quality of the entire article. Further, conventionally, it has been common to attach a slide fastener in a straight line to an article that is a fastener attaching member. However, in recent years, a slide fastener is curved, for example, from the viewpoint of convenience and design of the article. It has come to be attached to a fastener-attached member in a bent state.

In this regard, in the slide fastener as described in Patent Document 1 described above, the tape main portion of the fastener tape to which the continuous fastener element is fixed is used as an opening / closing portion of an article (for example, a clothing article) serving as a fastener attaching member. In order to smoothly sew the slide fastener and the fastener-attached member with a sewing machine, the main part of the fastener tape exposed outside the fastener element in the tape width direction is used. It was necessary to secure the width dimension at the portion as a seam allowance. In addition, when the slide fastener is attached to the fastener-attached member in a curved shape, the tape main body portion that hits the outer periphery of the slide fastener may partially rise or sink, In some cases, a wavy large wrinkle is generated in the tape extension portion (tape extension portion bent in a concave shape) that hits the inner peripheral portion of the slide fastener.

In order to solve such a problem, the inventors of the present application have previously described a stringer without a fastener tape and an article with a slide fastener configured using the stringer without the fastener tape in International Application No. PCT / JP2013 / 083604. An international application was filed.

As shown in FIGS. 15 and 16, the stringer without a fastener tape according to this application includes a plurality of continuous fastener elements 212 formed from monofilaments, and a thin thread in which the fastener elements 212 are sewn in series by a sewing thread 213. The element fixing member 214 is inserted along the fastener length direction between the upper and

lower leg portions

212b and 212c of the fastener element 212, and the sewing thread 213 is connected to the upper leg portion 212b. The element fixing member 214 is pierced between the fastener elements 212 adjacent to each other in the fastener length direction, and the fastener element 212 and the element fixing member 214 are sewn together. In addition, the stringer without the fastener tape is aligned with the cloth 205 of the garment 201 as the fastener attachment, and the cloth 205 is formed by the main sewing of the second sewing thread 206 using the slide fastener sewing machine. By sewing and fixing, an article with a slide fastener constructed using a stringer without a fastener tape is obtained.

According to the above-described stringer without a fastener tape or an article with a slide fastener configured using the stringer without the fastener tape, the slide fastener can be reduced in weight and cost, and the slide fastener is bent into a curved shape. Even in the state, the present invention has an excellent effect that the stringer without the fastener tape can be attached to the fastener attaching member with a good appearance.

By the way, as in recent years, articles such as clothes to which slide fasteners are attached have been produced in a variety of small quantities, and accordingly, the fabric 205 shown in FIGS. 15 and 16 has various thicknesses. However, for example, when the thickness of the fabric 205 in FIG. 16 is increased due to the use or design of the article, the fabric 205 and the plurality of fastener elements 212 are placed on the upper wing plate 233 and the lower side of the slider 230. The sliding resistance of the slider 230 increases due to the pressure contact with the blade plate 234, or the cloth 205 is caught between the upper blade plate 233 and the lower blade plate 234 of the slider 230, so that the slider 230 slides. There is a problem that the dynamic operation cannot be performed easily. Further, there is a problem that the sewing thread 213 and the second sewing thread 206 are easily cut by friction with the slider 230.

In order to solve such a problem, for example, one type of slider in which the distance between the upper blade and the lower blade is set relatively large is prepared, or a plurality of different intervals between the upper blade and the lower blade are provided. It is conceivable to prepare different types of sliders.

However, in the former case, for example, when a stringer without a fastener tape is attached to a thin fabric to form a slide fastener, the fastener element is rattled in the element guide path of the slider when the slider slides. It becomes easy to stick, and there arises a demerit that the sliding property of the slider is lowered and the engagement of the fastener element is deteriorated. On the other hand, in the latter case, since it is necessary to prepare a plurality of types of sliders according to the thickness of the fabric, a burden on the cost is increased, resulting in a disadvantage that it is not economical.

The present invention has been made in view of the above-described conventional problems, and a specific object thereof is to adopt a stringer without a fastener tape, thereby reducing the weight and cost of the slide fastener and bending it into a curved shape. A stringer without fastener tape that is economically superior and can be attached smoothly, and can ensure smooth sliding of the slider regardless of the thickness of the adherend (fabric) of the slide fastener. It is providing the slide fastener without a fastener tape which has these, and the articles | goods with a slide fastener which have the slide fastener.

In order to achieve the above object, the fastener tape-less stringer provided by the present invention is a stringer without a fastener tape that is attached to a stringer mounting portion disposed opposite to a fastener-attached member as a basic configuration. A plurality of continuous fastener elements formed from a monofilament, and a narrow element fixing member that is arranged along the length direction of the fastener and is sewn with a sewing thread. The fastener element includes a meshing head, an upper leg portion and a lower leg portion extending in the fastener width direction from the meshing head with the element fixing member interposed therebetween, and extending from the upper leg portion or the lower leg portion. A fastener tape comprising a connecting portion connected to the fastener element adjacent in the length direction. In the pullless stringer, the lower leg portion is arranged to bend from the first extension portion to the upper leg portion side, and a first extension portion extending continuously in the fastener width direction from the meshing head. And a second extending part extending in the fastener width direction closer to the upper leg part than the first extending part from the step part, and the fastener covering is provided by the step part. An accommodation space portion that can accommodate the stringer attachment portion of the landing member has a height dimension from the lower surface of the first extension portion to the lower surface of the second extension portion, and is below the second extension portion. It is the main feature that it is formed in the form.

In the stringer without a fastener tape of the present invention, the height dimension from the lower surface of the first extension portion to the lower surface of the second extension portion in the lower leg portion is from the lower surface of the first extension portion to the upper leg portion. It is preferable that the height is set to 5% or more and 25% or less of the height to the upper surface.

In the stringer without a fastener tape of the present invention, the upper leg portion and the second extension portion of the lower leg portion are sewn to the element fixing member by double ring stitching of the sewing thread. Is preferred. In this case, the looper thread of the sewing thread is disposed across the upper leg portion of the fastener element, and the needle thread of the sewing thread straddles the second extension portion of the lower leg portion and is adjacent to each other. It is particularly preferable that the element fixing member is pierced between the fastener elements and crossed with the looper yarn.

Furthermore, in the stringer without a fastener tape of the present invention, the element fixing member is formed of a tape member having a woven structure, a tape member having a warp knitting structure, a tape member made of a nonwoven fabric, or a film member made of a synthetic resin. It is preferable.

And according to this invention, the stringer without a fastener tape which has the structure mentioned above is attached in the state in which the stringer attachment part was accommodated in the said accommodation space part by the said stringer attachment part of the said fastener attaching member. In addition, there is provided a slide fastener without a fastener tape, the main feature of which is that a slider is slidably attached to an element row formed by the fastener elements.
Furthermore, according to this invention, the article | item with a slide fastener which has a fastener fastener without a fastener tape which has the structure mentioned above is provided.

A stringer without a fastener tape provided by the present invention (hereinafter sometimes simply referred to as “stringer”) is formed from a monofilament, and has a continuous fastener element in a coil shape or a zigzag shape, and a narrow element fixing member. have. The narrow element fixing member is inserted between the upper and lower leg portions of the fastener element along the fastener length direction, and the continuous fastener element is fixed to the narrow element disposed between the upper and lower leg portions. The member is sewn in series with sewing thread.

Here, the fastener tape refers to the upper leg portion and the lower leg portion in contact with the upper leg portion or the lower leg portion on the outer surface of the upper leg portion or lower leg portion of the fastener element (the surface opposite to the surface on which the upper and lower leg portions face each other). It is a tape member for fixing a lower leg part, and is a member different from the element fixing member of the present invention inserted between upper and lower leg parts. That is, the stringer according to the present invention has no so-called fastener tape for fixing the upper leg portion and the lower leg portion outside the upper leg portion or the lower leg portion, and has a new structure different from a conventional general stringer. It is comprised as a stringer without a fastener tape which has.

Further, in the present invention, the sewing thread is formed by straddling the upper leg portion and the lower leg portion of each fastener element in contact with each other and by inserting an element fixing member between the fastener elements adjacent to each other in the fastener length direction. The fastener element is sewn and fixed to the element fixing member. In this case, it is preferable that the element fixing member is not easily stretchable in the fastener length direction like a conventional core string, and has a hardly stretchable structure that hardly stretches in the fastener length direction.

In such a stringer that does not use the fastener tape according to the present invention, the fastener element is sewn to an element fixing member (particularly, a hardly stretchable element fixing member) inserted between the upper and lower leg portions. For this reason, even if it does not use the conventional fastener tape as a structural member of a stringer, the attachment pitch of a fastener element can be stably hold | maintained by an element fixing member.

Therefore, by attaching the stringer of the present invention to the fastener attaching member to constitute the slide fastener or the article with the slide fastener, the slide fastener can be reduced in weight and cost can be reduced, or the fastener tape can be used in the conventional role. It can also be used for purposes other than (for example, decoration purposes).

Furthermore, according to the present invention, since a stringer or a slide fastener can be configured without using a fastener tape, for example, the stringer of the present invention can be stably attached to a fastener-attached member in a bent state. it can. Further, in this case, since there is no occurrence of lifting or sinking of the fastener tape or wavy wrinkles, which is a problem with conventional slide fasteners, it is possible to improve the appearance (appearance quality) of articles with slide fasteners. it can.

Further, according to the present invention, the lower leg portion of each fastener element is provided with a first extension portion extending continuously in the fastener width direction from the meshing head portion, and bent from the first extension portion to the upper leg portion side. And a second extending portion extending from the step portion closer to the upper leg portion than the first extending portion in the fastener width direction. Further, each fastener element has an accommodation space portion that is formed below the second extension portion by having the step portion at the lower leg portion, and can accommodate the stringer attachment portion of the fastener-attached member. The space portion has a height dimension from the lower surface of the first extending portion to the lower surface of the second extending portion in the lower leg portion.

Thereby, when the product is manufactured by attaching the stringer of the present invention to the stringer attaching portion of the fastener attaching member (for example, the fabric) in a state where the stringer attaching portion is accommodated in the accommodating space portion. The height of the entire stringer is stably secured at a certain size by the height dimension from the lower surface of the first extension portion of the lower leg portion of the fastener element to the upper surface of the upper leg portion.

At the same time, even if the fastener attaching member (fabric) has various thicknesses, the thickness of the fastener attaching member is absorbed by the housing space of the fastener element, and the fastener is attached from the lower surface of the fastener attaching member. The height dimension from the lower surface of the first leg of the lower leg part to the upper surface of the upper leg part of the fastener element (that is, the height dimension of the entire stringer) is less than the height dimension of the upper leg part of the element Can be small.

Therefore, when one kind of slider set to a predetermined size with a gap between the upper blade and the lower blade is slidably attached to the element row formed by the fastener elements of the stringer of the present invention In addition, for example, even if the thickness of the fastener attaching member is thin, the height of the entire stringer is secured at a certain size by the upper leg portion of the fastener element and the first extension portion of the lower leg portion, When the slider slides, it is possible to prevent the slider from rattling.

On the other hand, for example, even if the thickness of the fastener attaching member is large, the thickness of the fastener attaching member is absorbed by the accommodating space portion of the fastener element, and the height dimension of the entire stringer is equal to that of the lower leg portion as described above. It can prevent becoming larger than the fixed height dimension from the lower surface of a 1st extension part to the upper surface of an upper leg part. As a result, when the slider is slid, it is possible to effectively prevent the fastener element and the fastener attaching member from being pressed against the slider upper blade and the lower blade and the fastener attaching member from being caught in the slider. Therefore, it is possible to stably ensure light and smooth sliding of the slider. In addition, since the sewing thread for sewing the fastener element does not easily come into strong contact with the slider, the problem that the sewing thread easily breaks can be solved.

In such a stringer of the present invention, the height dimension from the lower surface of the first extending portion to the lower surface of the second extending portion in the lower leg portion of the fastener element is such that the lower surface of the first extending portion extends to the upper surface of the upper leg portion. The height is set to 5% or more and 25% or less. Thereby, the stringer of the present invention can be stably attached to the stringer attachment portion of the fastener attaching member in a state where the fastener element holds an appropriate posture, and when the stringer is attached to the fastener attaching member Further, the thickness of the fastener attaching member can be appropriately absorbed by the accommodation space portion of the fastener element. Furthermore, when the slide fastener is formed, the posture of the fastener element can be made difficult to tilt in the element guide path of the slider.

In the stringer of the present invention, the upper leg portion and the second extension portion of the lower leg portion are sewn to the element fixing member by double ring stitching of sewing threads. Thereby, when sewing the fastener element with respect to the element fixing member, the upper leg portion and the lower leg portion of the fastener element can be efficiently sewn and fixed to the element fixing member, so that productivity can be improved. In addition, the upper leg portion and the lower leg portion are firmly fixed to the element fixing member by double chain stitching of the sewing thread, and further, for example, even when the sewing thread is broken, the sewing thread is hardly frayed.

Especially in this case, the looper thread of the sewing thread for performing the double chain stitch is disposed across the upper leg portion of the fastener element. Further, the needle thread of the sewing thread crosses over the second extending part of the lower leg part and pierces the element fixing member between the mutually adjacent fastener elements to cross the looper thread. Thereby, when the stringer of the present invention is attached to the stringer attachment portion of the fastener attaching member, the needle thread of the sewing thread can be covered and protected by the fastener attaching member. As a result, the needle thread of the sewing thread is hardly exposed to the outside, so that it is more difficult to cut than the looper thread of the sewing thread straddling the upper leg portion of the fastener element, and it is more effective that the sewing thread frays. Can be prevented.

Furthermore, in the stringer of the present invention, as the element fixing member, a tape member having a woven structure, a tape member having a warp knitting structure, a tape member made of a nonwoven fabric, or a film member made of a synthetic resin can be used. By forming the element fixing member with such a tape member or film member, it is possible to make the element fixing member less likely to expand and contract in the length direction of the fastener with a simple structure. Can be held stably.

Moreover, since the cross section of such a tape member or film member has a flat shape with a small dimension in the thickness direction and a large dimension in the width direction, the tape member or film member is interposed between the upper and lower leg portions of the fastener element. It can be made easy to insert. Further, for example, when the upper and lower leg portions of the fastener element are sewn to the tape member or the film member using a sewing machine, the sewing needle can be stably pierced to the tape member or the film member, and the sewing work can be performed smoothly. be able to.

In the slide fastener and the article with the slide fastener provided by the present invention, the stringer without the fastener tape having the above-described configuration is accommodated in the stringer attachment portion of the fastener attaching member, and the stringer attachment portion is accommodated in the accommodation space portion. It is attached in the state. Further, a slider is slidably attached to the element row formed by the fastener elements.

The slide fastener without a fastener tape configured as described above and the article with the slide fastener have a fastener element sewn on the element fixing member as described above, and therefore, a fastener tape may not be used as a constituent member of the slide fastener. The mounting pitch of the fastener element can be stably held.

That is, in the present invention, the fastener element mounting pitch can be stably held at a predetermined size, and at the same time, the fastener tape, which has conventionally been an essential component of the slide fastener, can be omitted. Light weight and cost reduction can be realized.

Furthermore, when the fastener tape is omitted and the slide fastener is configured, the stringer can be stably attached to the fastener attaching member in a bent state, for example, in a curved shape. Further, in this case, since there is no occurrence of lifting or sinking of the fastener tape or wavy wrinkles, which is a problem with conventional slide fasteners, it is possible to improve the appearance (appearance quality) of articles with slide fasteners. it can.

Further, the height from the lower surface of the first extension portion of the lower leg portion of the fastener element to the upper surface of the upper leg portion ensures that the overall stringer height is stably secured at a certain size, and at the same time Even if the stringer attachment portion of the adherend (fabric) has various thicknesses, the stringer attachment portion extends from the lower surface of the first extension portion to the lower surface of the second extension portion in the lower leg portion of the fastener element. If the thickness is less than the height dimension, the thickness of the stringer mounting portion can be reliably absorbed by the accommodating space portion of the fastener element.

Thereby, even when the thickness of the stringer attachment portion in the fastener attaching member is thin, for example, the slider can be made less likely to rattle when the slider slides. Even when the stringer attachment portion is thick, it is possible to stably ensure light and smooth sliding of the slider.

The meshing head 21 of the fastener element 20 is formed in the vertical direction so as to straddle the upper leg portion 22 and the lower leg portion 23, and includes a portion that bulges in the front-rear direction at an intermediate portion in the vertical direction. The upper leg portion 22 extends substantially parallel to the fastener width direction from the meshing head 21, and the upper surface (upper end portion) of the upper leg portion 22 is arranged so as to be substantially parallel to the surface of the fabric 5. .

The lower leg portion 23 of the fastener element 20 is arranged so as to be continuously extended from the meshing head portion 21 in the fastener width direction and bent from the first extension portion 23a to the upper leg portion 22 side. And a second extending portion 23c that extends closer to the upper leg portion 22 than the first extending portion 23a and extends in the fastener width direction. In this case, the lower surface (lower end portion) of the first extension portion 23a and the lower surface (lower end portion) of the second extension portion 23c are arranged so as to be substantially parallel to the surface of the fabric 5, and the second The extension part 23c is formed longer in the fastener width direction than the first extension part 23a.

Further, since the step portion 23b is formed in the lower leg portion 23, the lower surface of the second extending portion 23c is arranged above the lower surface of the first extending portion 23a in the element height direction. In this case, the vertical dimension (height dimension) B between the upper surface of the upper leg portion 22 and the lower surface of the second extending portion 23 c of the lower leg portion 23 is the upper surface of the upper leg portion 22 and the second leg portion 23. It is set smaller than the height dimension A between the lower surface of the 1 extension part 23a. Also. Since the lower leg portion 23 is formed with the step portion 23b as described above, the fastener element 20 can accommodate the stringer attachment portion 5a of the fabric 5 below the second extension portion 23c. A possible accommodation space 25 is formed.

In this case, the height dimension A from the lower surface of the first extending portion 23a to the upper surface of the upper leg portion, which is the height dimension of the fastener element 20, is, for example, a partition formed on an upper blade plate 33 (to be described later) of the slider 30. The distance between the lower surface of the portion 33a and the upper surface of the lower wing plate 34 is set smaller. Further, the height dimension A of the fastener element 20 is large enough to prevent the left and right fastener elements 20 from rattling in the vertical direction in the element guide path of the slider 30. For example, the lower surface of the above-described partition portion 33a and the lower wing It is preferable that the distance between the upper surfaces of the plates 34 is set to be 85% or more.

The accommodation space 25 of the fastener element 20 has a height dimension C from the lower surface of the first extension 23a to the lower surface of the second extension 23c, and the height of the accommodation space 25 ( That is, the height dimension (C) from the lower surface of the first extending portion 23a to the lower surface of the second extending portion 23c is set to a size of 5% to 25% of the height dimension A of the fastener element 20. Yes.

The height dimension C of the accommodation space 25 is 5% or more of the height dimension A of the fastener element 20, and when expressed by specific numerical values, the height C of the accommodation space 25 is 0.1 mm. By the above, the size (height) of the accommodation space 25 can be appropriately secured, and the fabric 5 is accommodated in the accommodation space 25 when the stringer 1 is attached to the fabric 5 as will be described later. The thickness of the fabric 5 can be absorbed by the step portion 23 b of the lower leg portion 23.

The absorption referred to here means that the sum of the dimension B and the thickness of the fabric 5 does not exceed or exceeds the dimension A depending on the height dimension C of the accommodation space 25, but the exceeding size is slight. Say there is. In other words, the thickness of the fabric 5 is reduced when the height dimension A of the fastener element 20 is used as a reference. In other words, the thickness of the fabric 5 is simply added to the height dimension A. Instead of being taken into the height dimension C of the storage space 25, the thickness of the fabric 5 does not appear as it is in the overall height dimension of the fastener element 20 to which the fabric 5 is attached. . Moreover, the state accommodated in the accommodation space 25 is, in other words, a state in which the edge portion of the stringer attachment portion 5a of the fabric 5 that is a fastener attaching member is disposed away from the step portion 23b in the fastener width direction. The state attached by.

As described above, when the thickness of the fabric 5 is absorbed by the stepped portion 23b of the lower leg portion 23, when the slide fastener 3 is formed, the stringer 1 causes the upper wing plate 33 and the lower wing plate 34 of the slider 30 to be described later. Therefore, the sliding resistance of the slider 30 can be suppressed from increasing, and the sliding operation of the slider 30 can be performed lightly. Further, the first sewing thread 13 for sewing the fastener element 20 to the element fixing member 14 and the second sewing thread 6 for sewing the stringer 1 to the fabric 5 can be made difficult to break due to friction with the slider 30. Moreover, since the below-mentioned needle thread 13b straddling the 2nd extension part 23c of the lower leg part 23 among the 1st sewing threads 13 will be covered with the fabric 5, this needle thread 13b is not exposed outside. It becomes like this.

On the other hand, when the height C of the housing space 25 is 25% or less of the height A of the fastener element 20, the second extension 23 c of the lower leg 23 is prevented from being too close to the upper leg 22. it can. Thereby, the space | interval between the 2nd extension part 23c of the lower leg part 23 and the upper leg part 22 is ensured appropriately, it suppresses that the element fixing member 14 is crushed more than necessary, and the element fixing member 14 is It is possible to prevent bending and undulation in the front and back direction. Furthermore, when the slide fastener 3 is formed, the interval between the second extending portion 23c (or the fabric 5) of the lower leg portion 23 and the lower wing plate 34 described later of the slider 30 is prevented from becoming too large. Thereby, when the left and right element rows 11 are engaged, the posture of the fastener element 20 is not easily tilted in an element guide path, which will be described later, of the slider 30, so that it is possible to prevent the occurrence of engagement failure.

In the present invention, the height dimension A of the fastener element, the height dimension B between the upper surface of the upper leg part and the lower surface of the second extension part 23c of the lower leg part, and the height dimension C of the housing space part 25 Each size and ratio can be arbitrarily determined in consideration of the size of the stringer, the type and thickness of the fastener-attached member to which the stringer is attached, but as an example here, The specific size of each dimension in the stringer 1 of the first embodiment will be introduced.

In the stringer 1 of the first embodiment, the height dimension A of the fastener element 20 is set to 2.6 mm, and the width dimension of the fastener element 20 (that is, the connecting portion from one end of the fastener element 20 on the side of the meshing head 21). The dimension in the left-right direction to the other end on the 24th side) D is set to 4.9 mm. Moreover, the height dimension B between the upper surface of the upper leg part 22 and the lower surface of the 2nd extension part 23c of the lower leg part 23 is set to 2.1 mm, and the height dimension C of the accommodation space part 25 is It is set to 0.5 mm.

Furthermore, in the first embodiment, in the width direction of the fastener element 20, the width dimension E from the boundary between the stepped portion 23b of the lower leg portion 23 and the second extending portion 23c to the edge of the fastener element 20 on the connecting portion 24 side. Is set to 2.8 mm. In this case, it is preferable that the width dimension E is set to 20% to 70% of the width dimension D of the fastener element 20.

When the width dimension E is 20% or more of the width dimension D of the fastener element 20, the fastener element 20 can be stably sewn to the element fixing member 14 by double ring stitching of the first sewing thread 13 to be described later. it can. Moreover, when the width dimension E is 70% or less of the width dimension D of the fastener element 20, the width dimension of the first extension portion 23 a of the lower leg portion 23 can be appropriately secured, and the slide fastener 3 is formed. The rattling of the fastener element 20 with respect to the slider 30 can be made difficult to occur.

Further, in the case of the first embodiment, as shown in FIGS. 2 and 4, the connection of the other fastener element 20 from the end edge on the connection portion 24 side of the one fastener element 20 in a state where the left and right stringers 1 are engaged with each other. The so-called chain width dimension F, which is the width dimension to the edge on the part 24 side, is set to 8.2 mm.

The element fixing member 14 to which the fastener elements 20 of the first embodiment are attached at a predetermined pitch is a tape member having a woven structure, preferably a set of a plurality of warps and two single yarns aligned. A tape member woven in a plain weave structure woven in a single weave with the wefts described above is used. The tape member woven in such a plain weave structure has a flat cross-sectional shape with a small dimension in the thickness direction and a large dimension in the width direction, and the length of the fastener is obtained by weaving the warp with weft. It has a structure that is difficult to expand and contract, with reduced direction expansion and contraction. In addition, an ear portion is formed on one side edge portion of the tape member by sequentially hooking the next weft and connecting the loop folded ends.

In addition to the tape member woven into the plain weave structure, the element fixing member 14 is a tape member having a warp knitted structure in which chain knitting yarns are arranged on each wale, a tape member made of a nonwoven fabric, Alternatively, a film member made of a synthetic resin can be used.

Such an element fixing member 14 is configured such that the dimension in the fastener width direction (also referred to as the tape width direction) is at least twice the dimension in the tape thickness direction in a no-load state. The dimension of the fixing member in the fastener width direction is set to 2.5 times or more and 3.5 times or less of the dimension in the tape thickness direction.

Here, the no-load state refers to a state in which the element fixing member 14 is removed from the fastener element 20 and an artificial external force such as tension or compression is not applied to the element fixing member 14. Since the element fixing member 14 has the dimensions as described above, the element fixing member 14 has a structure that hardly stretches in the fastener length direction.

As the element fixing member 14, for example, a core string called a knit cord obtained by knitting the periphery of the fastener element 20 between the upper and

lower leg portions

22 and 23 in a state where a plurality of yarns are bundled together is inserted. It is also possible to do. However, in the knit cord in which a plurality of yarns are bundled in this way, the plurality of yarns extend in the fastener length direction, and each yarn has waviness (crimping) in the fastener width direction and the fastener thickness direction. Since it is easy to expand and contract, it is not suitable as the element fixing member 14.

Further, in the first embodiment, by using the element fixing member 14 having a flat cross section, the element fixing member 14 can be easily inserted between the upper and

lower leg portions

22 and 23 of the fastener element 20. As will be described later, when sewing the upper and

lower legs

22 and 23 to the element fixing member 14 using a sewing machine, the sewing needle is stably inserted into the element fixing member 14 so that the sewing work can be performed smoothly. Can do.

Next, a method for manufacturing the above-described stringer 1 of the first embodiment will be described.
First, the fastener element 20 of Example 1 is formed. For example, a monofilament made of a thermoplastic resin such as polyamide or polyester is formed so as to be wound in a coil shape, and then the element fixing member 14 is disposed between the formed upper leg portion 22 and lower leg portion 23 in the element length direction ( Insert along the length of the fastener. At this time, the element fixing member 14 is inserted into the fastener element 20 such that one end portion in the width direction is in contact with the connecting portion 24 of the fastener element 20.

Subsequently, in a state where the element fixing member 14 is sandwiched between the upper and

lower leg portions

22, 23, a predetermined portion on the connecting portion 24 side of the lower leg portion 23 is pressed toward the upper leg portion 22 by a heat press or the like, A step portion 23 b is formed in the lower leg portion 23. At this time, when the lower leg portion 23 is pressed, the element fixing member 14 is sandwiched (held) between the upper leg portion 22 and the second extending portion 23 c of the lower leg portion 23. Thereby, the fastener element 20 of the first embodiment is formed.

Furthermore, with respect to the fastener element 20 obtained in this way, the element fixing member 14 in contact with the connecting portion 24 is sandwiched between the upper leg portion 22 and the second extension portion 23c of the lower leg portion 23, Using the sewing machine for element sewing, the upper leg portion 22 and the second extending portion 23c of the lower leg portion 23 are fixed to the front surface and the back surface of the element fixing member 14 by double chain stitching of the first sewing thread 13, respectively. As a result, the stringer 1 of the first embodiment as shown in FIGS. 3 to 5 is manufactured.

In this case, the looper thread 13a of the first sewing thread 13 that performs double chain stitching straddles the upper leg 22 while directly contacting the upper leg 22 of the fastener element 20 on the surface side of the element fixing member 14. Further, the needle thread 13b of the first sewing thread 13 passes through the second extending portion 23c while directly contacting the second extending portion 23c of the lower leg portion 23 of the fastener element 20 on the back surface side of the element fixing member 14. Further, the element fixing member 14 is pierced between the fastener elements 20 adjacent to each other and crossed with the looper yarn 13 a passing through the surface side of the element fixing member 14.

As a result, a seam is formed between the respective fastener elements 20, and the first sewing portion by double ring stitching of the first sewing thread 13 is formed so as to be exposed on the front side and the back side of the element row 11. The Moreover, since the part of the 2nd extension part 23c longer than the 1st extension part 23a of the lower leg part 23 is sewn on the element fixing member 14, a sewing process can be performed stably.

As described above, the fastener element 20 is fixed to the element fixing member 14 that is difficult to expand and contract in the fastener length direction by double ring stitching of the first sewing thread 13, so that the element fixing member 14 serves as a fastener element as an element fixing member. While maintaining the shape of 20, the attachment pitch (in other words, the space | interval between the meshing heads 21) of the fastener element 20 can be kept constant.

Further, since the first sewing thread 13 pierces the element fixing member 14 and holds the fastener element 20, the piercing position of the first sewing thread 13 with respect to the element fixing member 14 is difficult to shift, and the upper and lower leg portions of the fastener element 20. 22 and 23 can be firmly fixed and supported at predetermined positions of the element fixing member 14. For this reason, it is possible to prevent the upper and

lower leg portions

22 and 23 from moving with respect to the element fixing member 14.

In addition, it is preferable to employ double chain stitching as the stitch form of the first sewing thread 13 because the seam strength is excellent, and even if the first sewing thread 13 is cut, the first sewing thread 13 is unlikely to fray. can do. Furthermore, the stringer 1 without a fastener tape can be manufactured with high productivity by sewing the woven tape member 14 and the fastener element 20 together by double chain stitching.

Also, in general, when the fastener element is sewn to the fastener tape by double ring stitching of the sewing thread, when the needle thread of the sewing thread is cut, the fastener element is sewn rather than when the looper thread of the sewing thread is cut. It is known that fraying is likely to occur at the sewing portion (sewing line).

On the other hand, in the first embodiment, in particular, the fastener element 20 is sewn so that the needle thread 13b of the first sewing thread 13 that performs double chain stitching straddles the second extending portion 23c of the lower leg portion 23. Has been. That is, when the stringer 1b of the first embodiment is sewn to the fabric 5 and the slide fastener 3 is formed by arranging the needle thread 13b that is liable to fray at the sewn portion when it is cut on the lower leg portion 23 side. Since the exposed surface side of the needle thread 13b is covered and protected by the fabric 5, the needle thread 13b is not easily subjected to stress directly from the outside, and the needle thread 13b can be hardly cut.

Accordingly, the first sewing portion formed by the double ring stitching of the first sewing thread 13 for sewing the fastener element 20 becomes more difficult to fray, so that the lifespan of the stringer 1 and the slide fastener 3 can be extended.
In the present invention, as the stitch form of the first sewing thread 13, it is possible to employ other than the double ring stitch such as the main stitch.

Since the stringer 1 of the first embodiment manufactured in this way is formed without using the fastener tape, which is an essential constituent member of the conventional stringer, it is lighter than the conventional stringer, and Manufacturing costs can be reduced.

Furthermore, since the fastener element 20 is sewn to the element fixing member 14 having a structure that is difficult to expand and contract in the fastener length direction, the mounting pitch of the fastener element 20 can be adjusted by the element fixing member 14 without using a fastener tape. It can be held stably. Further, even when the stringer 1 of the first embodiment is bent into a curved shape or the like, unlike the stringer provided with the conventional fastener tape, the fastener tape does not rise or sink or wavy wrinkles are generated. .

The stringer 1 according to the first embodiment has a stringer sewing machine 40 as shown in FIG. 8 in a state in which the stringer 1 is aligned with the fabric 5 as a fastener attaching member as shown in FIGS. In use, the second sewing thread 6 is sewn and fixed to the fabric 5 by the main sewing. In this case, a material having a thickness equal to or less than the height C from the lower surface of the first extending portion 23a to the lower surface of the second extending portion 23c in the fastener element 20 is used as the fabric 5.

Further, when performing the sewing process by the stringer sewing machine 40, the stepped portion 23b is provided in the lower leg portion 23 of the fastener element 20 of the first embodiment, so that the position of the stringer 1 is aligned with the fabric 5. Sometimes, the stepped portion 23b can be used as a guide for positioning, and the fabric 5 protrudes over the stepped portion 23b to the first extending portion 23a side of the lower leg portion 23 (to the meshing head 21 side). Can be effectively prevented.

Furthermore, since the stepped portion 23b is provided in the lower leg portion 23 of the fastener element 20, the direction of the front and back of the stringer 1 can be easily identified. It is possible to prevent a mistake that the portion 22 is sewn to the fabric 5 in the direction in which the portion 22 contacts the fabric 5). This effect is particularly important when the stringer 1 is colored, printed, or the like, and expresses a specific design on the product in cooperation with the fabric 5.

In the first embodiment, the fastener element 20 and the element fixing member 14 are sewn to the fabric 5 with the second sewing thread 6 over the entire length direction of the fastener. The second sewing thread 6 straddles the second extension 23c of the upper leg portion 22 and the lower leg portion 23 of the fastener element 20 and pierces the element fixing member 14 and the fabric 5 between the adjacent fastener elements 20. As a result, the stringer 1 is sewn to the fabric 5.

In the first embodiment, the stringer 1 is sewn to the fabric 5 by the stringer sewing machine 40. The stringer 1 is accommodated in the recesses of the lower plate 42 of the sewing machine as shown in FIG. The stringer attaching portion 5a (opposite side edge) arranged opposite to each other is arranged in a gap formed between the upper plate 41 of the sewing machine and the second extending portion 23c of the lower leg portion 23 of the stringer 1. Done.

In this case, the sewing by the main sewing of the second sewing thread 6 is performed using a ball point needle as the sewing needle 43. This ball point needle is a needle whose tip is rounded in a spherical shape, and the diameter of the tip is preferably 0.2 mm or more and 0.6 mm or less.

By using the ball point needle in this way, even if the sewing needle 43 collides with the fastener element 20 during sewing, the position of the ball point needle is relatively displaced along the fastener element 20 in the front-rear direction, and the element fixing member 14 Further, since the fastener attaching member (fabric) 5 can be pierced, the sewing process can be performed smoothly and stably by avoiding damage to the fastener element 20 and breakage or bending of the sewing needle.

In addition, by adopting the main stitch as the stitch form of the second sewing thread 6, there is an advantage that the seam of the second sewing thread 6 is difficult to unravel and the strength is excellent, and in addition, the ball point needle is fastened to the fastener element 20 at the time of sewing. Even if the position of the ball point needle (in other words, the position where the needle pierces the element fixing member 14 and the fabric 5) is shifted due to collision with the stringer, the stringer 1 and the fabric 5 can be sewn smoothly and stably. Is possible.

When the ball point needle collides with the fastener element 20 when performing the sewing with the second sewing thread 6, in the stringer 1 of the first embodiment, the fastener element 20 is the element fixing member 14 as described above. Since the fastener element 20 is allowed to move slightly so as to avoid the ball point needle, the pitch of the fastener element 20 held by the element fixing member 14 becomes uneven. Can be prevented.

Further, in the present embodiment, the second sewing portion (particularly the portion where the second sewing thread 6 is exposed on the element row 11) by the main sewing of the second sewing thread 6 is the first sewing thread 13 in the fastener width direction. It arrange | positions so that it may overlap in the formation range of the 1st sewing part by double ring stitching. Here, the second sewing portion being within the formation range of the first sewing portion means that the tape width of the first sewing portion formed on the surface of the element row 11 (the upper surface of the upper leg portion 22 of the fastener element 20). It means that the second sewing portion formed on the surface of the element row 11 (the upper surface of the upper leg portion 22 of the fastener element 20) is disposed within the range of the direction.

Note that the second sewing thread 6 forming the second sewing portion on the element row 11 passes between the lower leg portions 23 of the adjacent fastener elements 20, penetrates the element fixing member 14, and further on the adjacent fastener elements 20. The fabric 5 is pierced between the legs 22. In this case, a part of the first sewing thread 13 is also located between the second sewing thread 6 and the upper surface of the upper leg portion 22 of the fastener element 20.

By performing the sewing process by the stringer sewing machine 40 as described above, the fastener element 20, the element fixing member 14, and the fabric 5 are the second sewing portion that is a part of the second sewing thread 6 on the element row 11. And a portion of the second sewing thread 6 appearing on the surface of the fabric 5 are sewn and fixed. In this case, as described above, the second sewing portion is formed such that the second sewing portion of the second sewing thread 6 overlaps the range of the first sewing portion of the first sewing thread 13, whereby the second sewing portion becomes the first sewing portion. Therefore, the appearance of the article to which the stringer 1 is attached can be improved.

In addition, since the second sewing portion of the second sewing thread 6 is formed on the surface of the fastener element 20 together with the first sewing portion of the first sewing thread 13 in a state where the stringer 1 is fixed to the fabric 5. Both the first sewing portion and the second sewing portion can withstand the wear caused by sliding of the slider 30 and the wear / collision caused by external factors. For this reason, compared with the case where the 2nd sewing part is spaced apart and formed from the 1st sewing part, it can prevent effectively that thread breakage etc. arise in the 1st sewing thread 13 and the 2nd sewing thread 6.

Even when the second sewing portion by the second sewing thread 6 is formed so as to overlap the range of the first sewing portion by the first sewing thread 13 as described above, the ball point needle is used as the sewing needle as described above. As a result, it is possible to perform sewing so that the needle point of the ball point needle divides the first sewing thread 13 and passes between the first sewing thread 13, so that the first sewing thread 13 is cut when the second sewing thread 6 is sewn. It can be made difficult to occur. In addition, in this invention, it is also possible to employ | adopt things other than a main stitch as a stitch form of the 2nd sewing thread | yarn 6. FIG.

As described above, the pair of left and right stringers 1 are sewn to the cloth (fastener attaching member) 5 such as clothes by the main sewing of the second sewing thread 6, and then the slider 30 is slid on the element rows 11 of both stringers 1. Mount it movable. Thereafter, the first stopper and the second stopper are formed so as to be adjacent to the front end and the rear end of the element row 11. Thereby, the slide fastener 3 without a fastener tape of the present Example 1 is formed.

Here, as shown in FIGS. 1 and 2, the slider 30 according to the first embodiment includes a slider body 31 and a handle 32 having an attachment shaft portion at one end. The slider body 31 connects the upper wing plate 33, the lower wing plate 34 spaced apart and in parallel with the upper wing plate 33, and the front end portions (shoulder side end portions) of the upper and

lower wing plates

33 and 34. Guiding pillars 35, an upper flange 37 erected from the left and right side edges of the upper wing plate 33 toward the lower wing plate 34, and a ridge 36 disposed on the left and right side edges of the lower wing plate 34. And a handle attachment portion 38 disposed on the upper surface of the upper wing plate 33. Further, the upper wing plate 33 includes a partition portion 33 a that protrudes downward at the center portion in the width direction of the upper wing plate 33.

Left and right shoulder openings are formed at the front end portion of the slider body 31 with the guide column 35 interposed therebetween, and a rear opening is formed at the rear end portion of the slider body 31. In addition, between the upper and

lower blades

33 and 34, an element guide path is formed so as to allow the left and right shoulder openings and the rear opening to communicate with each other, and through which the fabric 5 can be inserted together with the fastener element 20. .

Although not shown, a first stopper is attached to the fabric 5 adjacent to the front ends of the left and right element rows 11 so that the slider 30 does not fall off from the front end side of the element rows 11 at the front end of the element rows 11. It has been. Further, at the rear end of the element row 11, a second stopper is adjacent to the rear ends of the left and right element rows 11 so that the slider 30 does not fall off from the rear end side of the element row 11. It is attached to the fabric 5 so as to straddle.

In the present invention, the means for attaching the first and second fasteners to the fabric 5 is not particularly limited. For example, the first and second fasteners may be fixed to the fabric 5 by adhesion or welding, The metal first and second fasteners may be fixed to the fabric 5 by plastic deformation by caulking or the like. Further, for example, the second end can be formed by pressing the rear end portion of the element row 11 to crush and forming it wide, or by sewing it so as to cross the rear end portion of the element row 11. It is.

In the first embodiment, as described above, after the pair of left and right stringers 1 are sewn to the fabric 5, the slider 30 is attached to the element row 11 of the stringer 1, and the first and second fasteners are attached. The slide fastener 3 is formed by being attached to the fabric 5. However, in the present invention, after attaching the slider 30 to the element row 11 of the pair of left and right stringers 1, the stringer 1 can be sewn to the fabric 5 by the main sewing of the second sewing thread 6. However, in consideration of the efficiency and productivity of sewing with the second sewing thread 6, it is preferable to attach the slider 30, the first stopper, and the second stopper after the stringer 1 is sewn to the fabric 5.

In the garment 2 provided with the slide fastener 3 of the first embodiment shown in FIGS. 1 and 2 obtained as described above, the slide fastener 3 can be configured without using a fastener tape. Can be easily reduced in weight and cost.

Further, for example, even when the stringer 1 is attached to the opening / closing portion of the pocket portion provided on the chest or abdomen of the clothes while being bent in a curved shape or the like, the lifting of the fastener tape, which is a problem with the conventional slide fastener 3, is lifted. Therefore, the appearance (appearance quality) of the clothes 2 can be improved.

Further, when the stringer 1 is attached to the garment 2, the sewing machine 40 having the ball point needle can be used to easily and stably perform the attaching operation of the stringer 1 to the fabric 5, so that relatively simple sewing is performed. The clothes 2 can be finished beautifully in the process.

Furthermore, in the garment 2 with the slide fastener 3 according to the first embodiment, the step portion 23 b is provided in the lower leg portion 23 of the fastener element 20, so that the fabric 5 is held in the accommodation space portion 25 of the fastener element 20. The thickness of the fabric 5 can be substantially absorbed. Thereby, the overall height dimension of the stringer 1 is adjusted to the height dimension A between the upper surface of the upper leg portion 22 and the lower surface of the first extension portion 23a of the lower leg portion 23 in the fastener element 20, and the fabric 5 It becomes a constant size that does not depend on the thickness of the.

Thereby, for example, it is not necessary to prepare a plurality of types of sliders having different intervals between the upper and

lower blades

33 and 34, so that the economy can be improved and the stringer 1 and the clothes 2 can be provided at a low cost. Become.

Further, when the slider 30 is slid to open and close the left and right element rows 11, the position of the upper surface of the upper leg portion 22 of the fastener element 20 and the position of the lower leg portion 23 in the vertical direction in the element guide path of the slider 30.
