Abstract

A concealed slide fastener (10) has restricting members (11) which, when left and right continuous element rows (3) are engaged with each other, restrict movement of folded tape sections of left and right fastener tapes (2), which are butted against each other, in the direction in which the folded tape sections separate from each other. The restricting members (11) are mounted to the inner surfaces of folded-back sections of the fastener tapes (2) and are arranged at positions at which one side edge of each restricting member (11) makes contact with the inner surface of a corresponding folded tape section when the continuous element rows (3) engage with each other. Even if the left and right fastener tapes (2) are subjected to lateral forces when the continuous element rows (3) are engaged with each other, the restricting members (11) restrict movement of the folded tape sections to keep the left and right folded tape sections in a butted condition, so that the continuous element rows (3) can be stably concealed.

　本発明は、左右のエレメント列を噛合させたときに、ファスナーテープの外側に露出するテープ外面側から、噛合したエレメント列を見えないように隠蔽する隠蔽性に優れた隠しスライドファスナーに関する。 The present invention relates to a hidden slide fastener excellent in concealing property for concealing the meshed element rows so as not to be seen from the outer surface side of the tape exposed to the outside of the fastener tape when the left and right element rows are meshed.
　一般に、スライドファスナーは、噛合した左右のエレメント列がファスナーテープのテープ外面側に配されて露出する通常タイプのスライドファスナーと、噛合した左右のエレメント列を外側から見えないように隠蔽する隠しタイプのスライドファスナー（所謂、隠しスライドファスナー）の２種類の代表的なタイプに大別される。隠しスライドファスナーは、その隠蔽性から製品のデザイン性を妨げないという利点を生かして各種衣類や靴等の製品に好適に使用され、また近年では、自動車や列車の座席シート用シートカバー等にも使用されてきている。 Generally, a slide fastener is a normal type slide fastener in which the engaged left and right element rows are arranged on the outer surface of the fastener tape and exposed, and a hidden type that hides the engaged left and right element rows from the outside. There are roughly two types of slide fasteners (so-called hidden slide fasteners). Hidden slide fasteners are used favorably for products such as various clothing and shoes, taking advantage of the fact that they do not hinder product design due to their concealment properties. In recent years, they are also used for seat covers for seats for automobiles and trains. Has been used.
　このような隠しスライドファスナーの一例が、実公昭４９－４３４５４号公報（特許文献１）に開示されている。
　この特許文献１に記載されている隠しスライドファスナー６０は、図１３に示したように、左右一対のファスナーテープ６１と、各ファスナーテープ６１に縫着されたコイル状の連続エレメント列６２と、ファスナーテープ６１と連続エレメント列６２との間に配され、連続エレメント列６２とともにファスナーテープ６１に縫着される隠蔽片６３とを有している。 An example of such a hidden slide fastener is disclosed in Japanese Utility Model Publication No. 49-43454 (Patent Document 1).
As shown in FIG. 13, the hidden slide fastener 60 described in Patent Document 1 includes a pair of left and right fastener tapes 61, a coil-like continuous element row 62 sewn on each fastener tape 61, and a fastener. A concealing piece 63 is provided between the tape 61 and the continuous element row 62 and sewn to the fastener tape 61 together with the continuous element row 62.
　前記ファスナーテープ６１は、同ファスナーテープ６１の対向側側縁部が、テープ長さ方向に沿ってテープ幅方向にＵ字状に折り曲げられており、隠しスライドファスナー６０の露出面側に配されるテープ本体部６１ａと、同テープ本体部６１ａから連続して配され、Ｕ字状に折り曲げられたテープ折曲部６１ｃと、同テープ折曲部６１ｃの側端縁からテープ幅方向に延びた折り返し片部６１ｂとを有している。 In the fastener tape 61, the opposite side edge portion of the fastener tape 61 is bent in a U shape in the tape width direction along the tape length direction, and is disposed on the exposed surface side of the hidden slide fastener 60. The tape main body 61a, the tape bent portion 61c arranged continuously from the tape main body 61a and bent in a U shape, and the folded back extending from the side edge of the tape bent portion 61c in the tape width direction And one piece 61b.
　前記連続エレメント列６２は、噛合頭部６２ａと上下脚部６２ｂ，６２ｃとを有するファスナーエレメントが、隣接するファスナーエレメントと脚部連結部６２ｄを介して連結されて形成されている。また、この連続エレメント列６２は、上下脚部６２ｂ，６２ｃ間に芯紐６４が挿通され、且つ、同連続エレメント列６２の噛合頭部６２ａがテープ折曲部６１ｃから外方へ突出した状態となるように、縫着糸６５を用いて、折り返し片部６１ｂに隠蔽片６３を介して縫着されている。 The continuous element row 62 is formed by connecting a fastener element having a meshing head 62a and upper and lower leg portions 62b and 62c via an adjacent fastener element and a leg connecting portion 62d. In the continuous element row 62, the core string 64 is inserted between the upper and lower leg portions 62b and 62c, and the meshing head portion 62a of the continuous element row 62 protrudes outward from the tape bent portion 61c. As shown, the sewing thread 65 is used to sew the folded piece 61b through the concealing piece 63.
　この場合、連続エレメント列６２とともに縫着される隠蔽片６３は、同隠蔽片６３の一側縁が縫着糸６５の刺通位置よりも噛合頭部６２ａ側に延設されており、左右の連続エレメント列６２が噛合したときに左右の隠蔽片６３の一側縁同士が付き合わされるように配されている。 In this case, the concealing piece 63 sewn together with the continuous element row 62 is such that one side edge of the concealing piece 63 extends from the piercing position of the sewing thread 65 to the side of the meshing head 62a. When the continuous element row | line | column 62 meshes, it arrange | positions so that the one side edges of the right and left concealment piece 63 may be brought together.
　このような特許文献１の隠しスライドファスナー６０において、図示しないスライダーを摺動させて左右の連続エレメント列６２を噛合させた場合、左右のファスナーテープ６１の前記テープ折曲部６１ｃが付き合わされるとともに、ファスナーテープ６１と連続エレメント列６２との間にて左右の隠蔽片６３の一側縁同士も付き合わされる。これにより、噛合状態にある左右の連続エレメント列６２が、ファスナーテープ６１のテープ露出面側から見えないように隠蔽される。 In such a hidden slide fastener 60 of Patent Document 1, when the slider (not shown) is slid to engage the left and right continuous element rows 62, the tape bent portions 61c of the left and right fastener tapes 61 are attached together. The side edges of the right and left concealing pieces 63 are also attached between the fastener tape 61 and the continuous element row 62. Thereby, the left and right continuous element rows 62 in the meshing state are concealed so as not to be seen from the tape exposed surface side of the fastener tape 61.
　また、同隠しスライドファスナー６０では、左右の連続エレメント列６２が噛合しているときに、左右のファスナーテープ６１が、テープ幅方向に沿って外側へ引っ張る張力（横引き力）を受けた場合、同ファスナーテープ６１の左右のテープ折曲部６１ｃが互いに離間する方向へ移動し、左右のテープ折曲部６１ｃ間に間隙が形成される。その一方で、左右の隠蔽片６３は、左右のファスナーテープ６１が横引き力を受けても動くことはなく、同隠蔽片６３の一側縁同士が付き合わされた状態を維持することができる。 In the hidden slide fastener 60, when the left and right continuous element rows 62 are engaged, the left and right fastener tapes 61 receive tension (lateral pulling force) that pulls outward along the tape width direction. The left and right tape bent portions 61c of the fastener tape 61 are moved away from each other, and a gap is formed between the left and right tape bent portions 61c. On the other hand, the left and right concealing pieces 63 do not move even when the left and right fastener tapes 61 receive a lateral pulling force, and can maintain a state in which one side edges of the concealing pieces 63 are attached to each other.
　従って、特許文献１の隠しスライドファスナー６０は、左右の連続エレメント列６２が噛合している状態にて左右のファスナーテープ６１が上述のような横引き力を受けても、左右の隠蔽片６３が付き合わせられている状態を維持できるため、同隠蔽片６３により左右の連続エレメント列６２が隠蔽されて、連続エレメント列６２が露出することを防ぐことができる。 Therefore, in the hidden slide fastener 60 of Patent Document 1, even if the left and right fastener tapes 61 are subjected to the lateral pulling force as described above in a state where the left and right continuous element rows 62 are engaged, Since the attached state can be maintained, it is possible to prevent the left and right continuous element rows 62 from being concealed by the concealing piece 63 and the continuous element rows 62 from being exposed.
　特に、特許文献１によれば、ファスナーテープ６１の材質と隠蔽片６３の材質とを同じものとすることによって、上述のように左右のテープ折曲部６１ｃの間に間隙が形成されても、その間隙からファスナーテープ６１と同一色調の隠蔽片６３が見えるため、スライドファスナーの体裁を向上させることができるとしている。
実公昭４９－４３４５４号公報 In particular, according to Patent Document 1, by making the material of the fastener tape 61 and the material of the concealing piece 63 the same, even if a gap is formed between the left and right tape bent portions 61c as described above, Since the concealing piece 63 having the same color tone as that of the fastener tape 61 can be seen from the gap, the appearance of the slide fastener can be improved.
Japanese Utility Model Publication No. 49-43454
　前記特許文献１の隠しスライドファスナー６０では、連続エレメント列６２の噛合時に左右のファスナーテープ６１が横引き力を受けて外側に引っ張られても、左右の隠蔽片６３によって噛合状態の連続エレメント列６２を安定して隠蔽することができるものの、このとき、左右のテープ折曲部６１ｃ間には間隙が形成されてしまう。 In the hidden slide fastener 60 of Patent Document 1, even if the left and right fastener tapes 61 receive a lateral pulling force and are pulled outward when the continuous element rows 62 are engaged, the continuous element rows 62 engaged with the left and right concealing pieces 63 are engaged. Can be stably concealed, but at this time, a gap is formed between the left and right tape bent portions 61c.
　このため、例えば同隠しスライドファスナー６０を自動車のシートカバー等の製品に取着した場合、左右のファスナーテープ６１が横引き力を受けたときに、同ファスナーテープ６１のテープ折曲部６１ｃ間に形成される間隙によって、同隠しスライドファスナー６０が取着された製品の体裁が悪くなったり、また、同製品のデザイン性が損なわれたりするという問題があった。 For this reason, for example, when the hidden slide fastener 60 is attached to a product such as a seat cover of an automobile, when the left and right fastener tapes 61 are subjected to a lateral pulling force, the gap between the tape bent portions 61c of the fastener tape 61 is reduced. Due to the gap formed, there is a problem that the appearance of the product to which the hidden slide fastener 60 is attached is deteriorated and the design of the product is impaired.
　本発明は上記従来の課題に鑑みてなされたものであって、その具体的な目的は、連続エレメント列の噛合時に左右のファスナーテープが横引き力など受けて、テープ幅方向に沿って外側に引っ張られたとしても、左右のファスナーテープの折り返し部間に間隙が形成されることなく、或いは、間隙のできる領域が従来よりも小さく、連続エレメント列を安定して隠蔽するとともに外観品質の低下を防止することができる隠しスライドファスナーを提供することにある。 The present invention has been made in view of the above-described conventional problems, and a specific object thereof is that the right and left fastener tapes receive a lateral pulling force when meshing the continuous element rows, and the outer side along the tape width direction. Even if it is pulled, no gap is formed between the folded parts of the left and right fastener tapes, or the area where the gap is formed is smaller than the conventional one, and the continuous element row is stably concealed and the appearance quality is deteriorated. It is to provide a hidden slide fastener that can be prevented.
　上記目的を達成するために、本発明により提供される隠しスライドファスナーは、基本的な構成として、左右一対のファスナーテープの対向側側縁部が、テープ長さ方向に沿って、テープ幅方向にＵ字状に折り曲げられ、その折り曲げられたテープ折曲部の側端縁からテープ幅方向に延びた折り返し片部の外面に、噛合頭部を有する連続エレメント列が縫着糸により縫着され、左右の前記噛合頭部は、前記テープ折曲部から外方へ突出してなる隠しスライドファスナーであって、左右の前記連続エレメント列が噛合したときに、付き合わせ状態にある左右の前記テープ折曲部が互いに離間する方向へ移動することを規制する規制部材が、前記折り返し片部の内面に取着され、且つ、前記連続エレメント列の噛合時に同規制部材の一側縁が前記テープ折曲部の内面に当接する位置に配されてなることを最も主要な特徴とするものである。 In order to achieve the above object, the hidden slide fastener provided by the present invention has, as a basic configuration, the opposing side edges of a pair of left and right fastener tapes in the tape width direction along the tape length direction. A continuous element row having a meshing head is sewn with a sewing thread on the outer surface of a folded piece portion that is folded in a U shape and extends from the side edge of the folded tape bent portion in the tape width direction. The left and right meshing heads are hidden slide fasteners protruding outward from the tape folding part, and the left and right tape foldings are in an attached state when the left and right continuous element rows are meshed. A restricting member that restricts the movement of the parts in a direction away from each other is attached to the inner surface of the folded piece part, and one side edge of the restricting member is at the front when the continuous element row is engaged. It is an most important characterized by being disposed in a position where it comes into contact with the inner surface of the tape bent portions.
　このような本発明に係る隠しスライドファスナーにおいて、前記規制部材は、前記縫着糸によって、前記連続エレメント列とともに縫着されていることが好ましい。 In such a hidden slide fastener according to the present invention, it is preferable that the regulating member is sewn together with the continuous element row by the sewing thread.
　また、本発明に係る隠しスライドファスナーにおいて、前記規制部材は、小片状に形成された複数の規制本体部を有し、同規制本体部は、前記ファスナーテープの長さ方向に間欠的に縫着されていることが好ましい。特にこの場合、前記規制部材は、前記規制本体部をテープ長さ方向に連結する連結部を有していることが好ましい。 Further, in the hidden slide fastener according to the present invention, the restricting member has a plurality of restricting body portions formed in small pieces, and the restricting body portions are intermittently sewn in the length direction of the fastener tape. Preferably it is worn. Particularly in this case, it is preferable that the restricting member has a connecting portion for connecting the restricting main body portion in the tape length direction.
　一方、前記規制部材は、帯状に形成され、前記ファスナーテープの長さ方向に連続的に縫着されていても良い。特にこの場合、前記規制部材は、同規制部材の他側縁から切り込まれたスリットを有していることが好ましい。 On the other hand, the regulating member may be formed in a belt shape and continuously sewn in the length direction of the fastener tape. Particularly in this case, it is preferable that the restricting member has a slit cut from the other side edge of the restricting member.
　更に、本発明において、前記規制部材の前記折り返し片部に接触する第１面とは反対側の第２面に、前記縫着糸を収容する収容溝が凹設されていることが好ましい。 Furthermore, in the present invention, it is preferable that an accommodation groove for accommodating the sewing thread is recessed in a second surface opposite to the first surface that contacts the folded piece portion of the regulating member.
　本発明に係る隠しスライドファスナーは、左右の連続エレメント列が噛合したときに、付き合わせ状態にある左右のファスナーテープのテープ折曲部が互いに離間する方向へ移動することを規制する規制部材を有しており、この規制部材は、ファスナーテープの折り返し片部の内面に取着され、且つ、連続エレメント列の噛合時に同規制部材の一側縁がテープ折曲部の内面に当接する位置に配されている。 The hidden slide fastener according to the present invention has a restricting member that restricts movement of the tape bent portions of the left and right fastener tapes in the attached state from each other when the left and right continuous element rows are engaged with each other. The regulating member is attached to the inner surface of the folded piece portion of the fastener tape, and is arranged at a position where one side edge of the regulating member abuts the inner surface of the tape bent portion when the continuous element row is engaged. Has been.
　このような本発明の隠しスライドファスナーによれば、左右の連続エレメント列が噛合したときに、左右のファスナーテープのテープ折曲部が付き合わせられるとともに、規制部材が、同規制部材の一側縁をファスナーテープのテープ折曲部の内面に当接させて、テープ折曲部を内面側から押さえることができる。 According to such a hidden slide fastener of the present invention, when the left and right continuous element rows are engaged, the tape bent portions of the left and right fastener tapes are attached together, and the restricting member is one side edge of the restricting member. Can be brought into contact with the inner surface of the tape bent portion of the fastener tape to press the tape bent portion from the inner surface side.
　これにより、左右の連続エレメント列が噛合している状態にて、左右のファスナーテープが横引き力を受けてテープ幅方向の外側に向けて引っ張られても、付き合わせ状態にある左右のテープ折曲部が互いに離間する方向へ移動することを規制して、テープ折曲部の位置を安定して保持することができる。 As a result, even if the left and right fastener tapes receive a lateral pulling force and are pulled toward the outside in the tape width direction while the left and right continuous element rows are engaged, It is possible to stably hold the position of the tape bent portion by restricting the bent portions from moving in directions away from each other.
　このため、左右のテープ折曲部間に従来のような大きな間隙が形成されることはなく、左右のテープ折曲部同士が付き合せられた状態を維持して、噛合状態にある連続エレメント列をテープ露出面側から見えないように安定して隠蔽することができる。 For this reason, a continuous large element gap is not formed between the left and right tape bent portions, and the state where the left and right tape bent portions are attached to each other is maintained, and the continuous element row is in an engaged state. Can be stably hidden so that it cannot be seen from the exposed side of the tape.
　従って、本発明の隠しスライドファスナーが、例えばシートカバー等の製品に取着されて使用されたときに左右のファスナーテープに横引き力が加えられても、その製品の外観品質が低下することを防止できる。更に、本発明の隠しスライドファスナーは、簡単な構造で上述のような優れた隠蔽性を得ることができるため、従来の隠しスライドファスナーに比べて、コストの増大を招くこともない。 Therefore, when the hidden slide fastener of the present invention is attached to a product such as a seat cover and used, even if a lateral pulling force is applied to the left and right fastener tapes, the appearance quality of the product is deteriorated. Can be prevented. Furthermore, since the hidden slide fastener of the present invention can obtain the above-described excellent concealability with a simple structure, the cost is not increased compared to the conventional hidden slide fastener.
　本発明に係る隠しスライドファスナーにおいて、前記規制部材は、小片状に形成された複数の規制本体部を有し、同規制本体部は、前記ファスナーテープの長さ方向に間欠的に配置して、縫着されている。これにより、ファスナーテープに規制部材を縫着してもファスナーストリンガーの可撓性、特に折り返し片部における可撓性を容易に確保することができる。このため、スライダーを摺動させて隠しスライドファスナーを開閉する際に、スライダーを円滑に摺動させてスライドファスナーの開閉操作を安定して行うことができる。 In the hidden slide fastener according to the present invention, the restricting member has a plurality of restricting body portions formed in small pieces, and the restricting body portions are intermittently disposed in the length direction of the fastener tape. Have been sewn. Thereby, even if the regulating member is sewn on the fastener tape, the flexibility of the fastener stringer, particularly the flexibility at the folded piece portion can be easily ensured. For this reason, when the slider is slid to open and close the hidden slide fastener, the slider can be smoothly slid to open and close the slide fastener stably.
　この場合、前記規制部材は、規制本体部をテープ長さ方向に連結する連結部を有していることにより、規制部材をファスナーテープに縫着するときの縫製作業を容易に行うことができ、また、規制部材の縫着位置も安定させることができる。 In this case, the restriction member can easily perform a sewing operation when the restriction member is sewn to the fastener tape by having a connecting portion for connecting the restriction main body portion in the tape length direction. Further, the sewing position of the restricting member can be stabilized.
　一方、本発明において、前記規制部材は、帯状に形成され、前記ファスナーテープの長さ方向に連続的に縫着されていても良い。このように規制部材が連続した帯状体により形成されていることにより、左右のファスナーテープがテープ幅方向に沿って外側に引っ張られたときに、左右のテープ折曲部が離間する方向へ移動することを規制することができる。 On the other hand, in the present invention, the restriction member may be formed in a belt shape and continuously sewn in the length direction of the fastener tape. Thus, when the restricting member is formed of a continuous belt-like body, when the left and right fastener tapes are pulled outward along the tape width direction, the left and right tape bent portions move in the direction of separating. Can be regulated.
　この場合、前記規制部材が、同規制部材の他側縁から切り込まれたスリットを有していることにより、同規制部材が縫着されている折り返し片部を撓み易くすることができるため、スライドファスナーの開閉操作時にスライダーを円滑に摺動させることができる。 In this case, since the restricting member has a slit cut from the other side edge of the restricting member, the folded piece portion on which the restricting member is sewn can be easily bent. The slider can be smoothly slid during the opening and closing operation of the slide fastener.
　更に、本発明の隠しスライドファスナーにおいて、前記規制部材の露出する第２面には、縫着糸を収容する収容溝が凹設されている。これにより、連続エレメント列及び規制部材を縫着する縫着糸が収容溝に収容され、スライダーが連続エレメント列に沿って摺動する際に、同スライダーが、規制部材の第２面側を走行する縫着糸と干渉することを防ぐことができる。このため、スライダーが摺動するときの摺動抵抗を小さくできるとともに、縫着糸に糸切れが生じることも効果的に防止することができる。 Furthermore, in the hidden slide fastener of the present invention, an accommodation groove for accommodating a sewing thread is recessed in the exposed second surface of the restriction member. Thereby, the sewing thread for sewing the continuous element row and the regulating member is accommodated in the accommodation groove, and when the slider slides along the continuous element row, the slider travels on the second surface side of the regulating member. Interference with the sewing thread to be prevented can be prevented. For this reason, it is possible to reduce sliding resistance when the slider slides, and to effectively prevent thread breakage in the sewing thread.

The lower leg part 6c or the upper leg part 6b of the adjacent fastener element 6 has a leg part connecting part 6d.
　更に、連続エレメント列３は、同連続エレメント列３の上下脚部６ｂ，６ｃ間に芯紐７が挿通され、且つ、噛合頭部６ａがテープ折曲部２ｃからテープ幅方向（左右方向）の外方へ向けて突出した状態となるように、ファスナーテープ２に縫着されている。 Further, in the continuous element row 3, the core string 7 is inserted between the upper and lower leg portions 6b, 6c of the continuous element row 3, and the meshing head portion 6a extends from the tape bent portion 2c in the tape width direction (left-right direction). It is sewn on the fastener tape 2 so as to project outward.
　前記規制部材１１は、図３及び図４に示したように、薄肉の小片状に形成され、正面視にて矩形状を呈する複数の規制本体部１２と、同規制本体部１２をテープ長さ方向に連結する連結部１３とを有している。前記連結部１３は一定の幅寸法を有するフィルム状に形成されており、同連結部１３に、小片状の規制本体部１２がテープ長さ方向に所定の間隔をもって一体成形されているため、各規制本体部１２は連結部１３を介してひとつながりに連結されている。 As shown in FIGS. 3 and 4, the restriction member 11 is formed in a thin piece shape, and has a plurality of restriction main body portions 12 that are rectangular in front view, and the restriction main body portion 12 is a tape length. And a connecting portion 13 that is connected in the vertical direction. The connecting portion 13 is formed in a film shape having a constant width dimension, and a small piece of the regulation main body portion 12 is integrally formed with the connecting portion 13 at a predetermined interval in the tape length direction. Each regulation main body 12 is connected to each other through a connecting portion 13.
　この場合、小片状の規制本体部１２とフィルム状の連結部１３とは二色成形により形成されている。また、規制本体部１２は、ポリアミド、ポリアセタール、ポリプロピレン、ポリブチレンテレフタレートなどの硬質の合成樹脂を用いて成形され、連結部１３は、例えばポリウレタン、シリコーンゴム、熱可塑性エラストマーなどの規制本体部１２よりも軟質の合成樹脂を用いて成形されている。なお、本発明において、規制部材１１の材質は限定されるものではなく、任意に変更することができる。 In this case, the small piece-like regulation main body 12 and the film-like connecting portion 13 are formed by two-color molding. Further, the restriction main body 12 is formed using a hard synthetic resin such as polyamide, polyacetal, polypropylene, polybutylene terephthalate, and the connecting portion 13 is formed from the restriction main body 12 such as polyurethane, silicone rubber, or thermoplastic elastomer. Is also molded using a soft synthetic resin. In the present invention, the material of the regulating member 11 is not limited and can be arbitrarily changed.
　また、ファスナーテープ２の折り返し片部２ｂに縫着された規制部材１１（特に、規制本体部１２）は、折り返し片部２ｂのうち、ファスナーエレメント６が縫着された面とは反対側の面であって、連続エレメント列３が噛合したときに、同規制部材１１の一側縁がファスナーテープ２のテープ折曲部２ｃの内面に当接する位置に配されている。なお、本発明において、各規制部材１１の形状や寸法は特に限定されるものではないが、例えば規制部材１１を、同規制部材１１の他側縁とファスナーテープ２の折り返し片部２ｂ側の側縁とのテープ幅方向における位置を合わせて縫着したときに、同規制部材１１の一側縁がファスナーテープ２のテープ折曲部２ｃの内面に当接するように規制部材１１の形状や寸法を設定することが好ましい。 Further, the regulating member 11 (particularly, the regulating main body 12) sewn on the folded piece 2b of the fastener tape 2 is a surface of the folded piece 2b opposite to the surface on which the fastener element 6 is sewn. And when the continuous element row | line | column 3 meshes, it arrange | positions in the position which the one side edge of the same regulating member 11 contact | abuts to the inner surface of the tape bending part 2c of the fastener tape 2. FIG. In the present invention, the shape and dimensions of each regulating member 11 are not particularly limited. For example, the regulating member 11 is connected to the other side edge of the regulating member 11 and the folded piece 2b side of the fastener tape 2. The shape and dimensions of the regulating member 11 are adjusted so that one side edge of the regulating member 11 comes into contact with the inner surface of the tape bent portion 2c of the fastener tape 2 when the edge is sewn in alignment with the position in the tape width direction. It is preferable to set.
　本実施例１における前記スライダー４としては、従来の隠しスライドファスナーにおいて一般的に用いられているスライダーを用いることができる。例えば、このような隠しスライドファスナー用のスライダー４は、左右の側縁に逆Ｌ字断面の第１フランジが立設された下翼板と、同下翼板の前端部に立設された案内柱と、同案内柱の上面側周縁部から延設された第２フランジと、同第２フランジの上面にスライダー４摺動方向に延在する門型の引手取付柱４ａと、同引手取付柱４ａに回動自在に取着された引手４ｂとを有しており、下翼板と第１フランジとに囲まれるようにエレメント案内路が形成されている。 As the slider 4 in the first embodiment, a slider generally used in a conventional hidden slide fastener can be used. For example, the slider 4 for such a hidden slide fastener includes a lower wing plate in which a first flange having an inverted L-shaped cross section is erected on the left and right side edges, and a guide erected on the front end portion of the lower wing plate. A column, a second flange extending from a peripheral portion on the upper surface side of the guide column, a portal-type pull attachment column 4a extending in the sliding direction of the slider 4 on the upper surface of the second flange, and the pull attachment column An element guide path is formed so as to be surrounded by the lower wing plate and the first flange.
　上述のような本実施例１の隠しスライドファスナー１０を製造する場合、先ず、Ｕ字状に折り曲げられてない状態のファスナーテープ２を準備し、同ファスナーテープ２の折り返し片部２ｂとなる所定の部位に、コイル状の連続エレメント列３と規制部材１１とを配置して縫着糸５を用いて縫着する。 When manufacturing the hidden slide fastener 10 of the first embodiment as described above, first, a fastener tape 2 that is not folded into a U-shape is prepared, and a predetermined piece to be a folded piece 2b of the fastener tape 2 is prepared. A coil-shaped continuous element row 3 and a regulating member 11 are arranged at the site and sewn using the sewing thread 5.
　このとき、連続エレメント列３は、上下脚部６ｂ，６ｃ間に芯紐７を挿通し、且つ、噛合頭部６ａをテープ本体部２ａ側に向けた状態に配置される。また、規制部材１１は、その連結部１３を折り返し片部２ｂの内面に接触させ、且つ、左右の連続エレメント列３を噛合させたときに同規制本体部１２の一側縁がテープ折曲部２ｃの内面に当接するように配置される。そして、連続エレメント列３と規制部材１１とは、上述のような所定の位置に配置された状態で、縫着糸５の二重環縫いにより一緒に縫着される。 At this time, the continuous element row 3 is arranged in a state in which the core string 7 is inserted between the upper and lower leg portions 6b and 6c and the meshing head portion 6a faces the tape main body portion 2a side. Further, when the regulating member 11 is brought into contact with the inner surface of the folded piece 2b and the left and right continuous element rows 3 are meshed, one side edge of the regulating main body 12 is a tape bent portion. It arrange | positions so that it may contact | abut to the inner surface of 2c. And the continuous element row | line | column 3 and the control member 11 are sewn together by the double ring stitch of the sewing thread | yarn 5 in the state arrange | positioned in the above predetermined positions.
　特に、本実施例１の隠しスライドファスナー１では、規制部材１１における複数の小片状の規制本体部１２が間欠的に配されているものの、これらの規制本体部１２は連結部１３により一連に連結されている。このため、小片状の各規制本体部１２を１つ１つ位置合わせしなくても、規制部材１１の連結部１３をファスナーテープ２の所定位置に配置して縫製することにより、規制部材１１の縫製作業を煩雑にすることなく、各規制本体部１２を所定の位置へ容易に且つ安定して縫着することができる。 In particular, in the hidden slide fastener 1 of the first embodiment, although the plurality of small piece-like restriction main body portions 12 in the restriction member 11 are intermittently arranged, these restriction main body portions 12 are connected in series by the connecting portion 13. It is connected. For this reason, even if it does not align each piece-like regulation main-body part 12 one by one, by arrange | positioning the connection part 13 of the regulation member 11 in the predetermined position of the fastener tape 2, and sewing it, the regulation member 11 Each regulation main body 12 can be easily and stably sewn to a predetermined position without complicating the sewing operation.
　このようにして連続エレメント列３及び規制部材１１を同時にファスナーテープ２に縫着した後、同ファスナーテープ２を、テープ長さ方向に沿って、テープ幅方向にＵ字状に折り曲げる。これにより、そのＵ字状に折り曲げられたテープ折曲部２ｃから連続エレメント列３の噛合頭部６ａをテープ幅方向の外方に向けて突出させる。続いて、噛合頭部６ａがテープ折曲部２ｃから突出した状態のままファスナーテープ２に熱セットを行う。その後、左右の連続エレメント列３にスライダー４を摺動可能に取着することによって、本実施例１の隠しスライドファスナー１０が得られる。 In this way, after the continuous element row 3 and the regulating member 11 are simultaneously sewn to the fastener tape 2, the fastener tape 2 is bent in a U-shape in the tape width direction along the tape length direction. Thereby, the meshing head 6a of the continuous element row 3 is protruded outward in the tape width direction from the tape bent portion 2c bent in the U shape. Subsequently, heat setting is performed on the fastener tape 2 with the meshing head 6a protruding from the tape bent portion 2c. Then, the hidden slide fastener 10 of the first embodiment is obtained by slidably attaching the slider 4 to the left and right continuous element rows 3.
　このようにして得られた本実施例１の隠しスライドファスナー１０によれば、スライダー４を摺動させて左右の連続エレメント列３を噛合させたときに、左右のテープ折曲部２ｃが互いに付き合わされるとともに、規制部材１１がテープ折曲部２ｃの内面に当接して同テープ折曲部２ｃを押さえることができるため、左右のテープ折曲部２ｃが互いに付き合わされた状態を安定して保持することができる。これにより、噛合状態にある左右の連続エレメント列３を、互いに付き合せられている左右のテープ折曲部２ｃによってファスナーテープ２のテープ露出面側から見えないように隠蔽することができる。 According to the hidden slide fastener 10 of Example 1 obtained in this way, when the slider 4 is slid and the left and right continuous element rows 3 are engaged, the left and right tape bent portions 2c are brought into contact with each other. In addition, since the regulating member 11 can contact the inner surface of the tape bent portion 2c and press the tape bent portion 2c, the left and right tape bent portions 2c can be stably held in contact with each other. can do. As a result, the left and right continuous element rows 3 in the meshing state can be concealed from being visible from the tape exposed surface side of the fastener tape 2 by the left and right tape bent portions 2c attached to each other.
　特に、同隠しスライドファスナー１０は、左右の連続エレメント列３が噛合している状態にて、左右のファスナーテープ２が横引き力を受けてテープ幅方向に沿って外側に引っ張られた場合でも、硬質樹脂からなる規制本体部１２によって、左右のテープ折曲部２ｃが互いに離間する方向へ移動することを規制して左右のテープ折曲部２ｃの位置が変動することを防ぐため、左右のテープ折曲部２ｃが付き合わされた状態を安定して保持することができる。 In particular, the hidden slide fastener 10 is in a state where the left and right continuous element rows 3 are engaged with each other, even when the left and right fastener tapes 2 receive a lateral pulling force and are pulled outward along the tape width direction. In order to prevent the right and left tape bent portions 2c from moving in a direction away from each other by the restriction main body portion 12 made of hard resin, the left and right tape bent portions 2c are prevented from fluctuating. The state where the bent portion 2c is attached can be stably held.
　これにより、噛合状態にある連続エレメント列３が、ファスナーテープ２のテープ外面側から見えないように、左右のテープ折曲部２ｃによって隠蔽されている状態を維持することができる。従って、本実施例１の隠しスライドファスナー１０は、例えばシートカバー等の製品に取着された場合でも、連続エレメント列３を安定して隠蔽し、製品の体裁やデザイン性を維持することができる。 Thereby, it is possible to maintain the state in which the continuous element row 3 in the meshing state is concealed by the left and right tape bent portions 2c so as not to be seen from the tape outer surface side of the fastener tape 2. Therefore, even when the hidden slide fastener 10 according to the first embodiment is attached to a product such as a seat cover, for example, the continuous element row 3 can be stably hidden to maintain the appearance and design of the product. .
　更に、本実施例１の隠しスライドファスナー１０では、硬質の規制本体部１２がテープ長さ方向に間欠的に配されており、これらの規制本体部１２を連結する連結する連結部１３が軟質樹脂により成形されている。このため、規制部材１１が折り返し片部２ｂに縫着されていても、同折り返し片部２ｂの可撓性を確保することができる。 Further, in the hidden slide fastener 10 of the first embodiment, the hard regulation main body 12 is intermittently arranged in the tape length direction, and the connecting portion 13 that connects these regulation main bodies 12 is a soft resin. It is molded by. For this reason, even if the regulating member 11 is sewn to the folded piece 2b, the flexibility of the folded piece 2b can be ensured.
　従って、スライダー４を摺動させて隠しスライドファスナー１０を開閉する際に、ファスナーテープ２の折り返し片部２ｂをスライダー４のエレメント案内路の形状に沿って容易に撓ませながらスライダー４を円滑に摺動させることができる。このため、スライダー４の摺動抵抗が増大することを防いで、隠しスライドファスナー１０の開閉操作を円滑に行うことができる。 Accordingly, when the slider 4 is slid to open and close the hidden slide fastener 10, the folded piece 2 b of the fastener tape 2 is easily slid along the shape of the element guide path of the slider 4, and the slider 4 is smoothly slid. Can be moved. For this reason, the sliding resistance of the slider 4 is prevented from increasing, and the opening / closing operation of the hidden slide fastener 10 can be performed smoothly.
　なお、本実施例１の隠しスライドファスナー１０では、図３及び図４に示したように、小片状の各規制本体部１２が、一定の幅寸法を有するフィルム状の連結部１３により連結されて折り返し片部２ｂに縫着されているが、本発明はこれに限定されるものではない。例えば図５に実施例１の変形例を示したように、幅広部１３ａ’と幅狭部１３ｂ’が交互に配された連結部１３’の幅広部１３ａ’に、小片状の規制本体部１２を一体成形することによって、規制部材１１’を形成することも可能である。 In the hidden slide fastener 10 of the first embodiment, as shown in FIG. 3 and FIG. 4, each piece-shaped regulation main body portion 12 is connected by a film-like connection portion 13 having a certain width dimension. However, the present invention is not limited to this. For example, as shown in FIG. 5 as a modification of the first embodiment, a small piece-shaped regulation main body portion is formed on the wide portion 13a ′ of the connecting portion 13 ′ in which the wide portions 13a ′ and the narrow portions 13b ′ are alternately arranged. It is also possible to form the regulating member 11 ′ by integrally molding 12.
　このような規制部材１１’を用いて構成された隠しスライドファスナーであっても、規制部材１１の縫製作業を容易に行うことができる。また、同隠しスライドファスナーは、連続エレメント列３及び規制部材１１’が縫着された折り返し片部２ｂの可撓性を、前記実施例１の隠しスライドファスナー１０よりも更に向上させることができるため、スライダー４の摺動操作をより円滑に行うことが可能となる。 Even with a hidden slide fastener configured using such a regulating member 11 ′, the sewing work of the regulating member 11 can be easily performed. Further, the hidden slide fastener can further improve the flexibility of the folded piece 2b to which the continuous element row 3 and the regulating member 11 ′ are sewn, as compared with the hidden slide fastener 10 of the first embodiment. The sliding operation of the slider 4 can be performed more smoothly.
　更に実施例１では、例えば隠しスライドファスナーが使用される製品の用途等から折り返し片部２ｂに優れた可撓性が求められる場合などでは、規制部材１１に連結部１３を設けずに、小片状の各規制本体部１２を互いに連結させることなく折り返し片部２ｂに独立に配置して縫着することができる。また、例えば規制部材１１における各規制本体部１２のテープ長さ方向における寸法をより短く設定することによって、折り返し片部２ｂの可撓性を更に向上させることも可能である。 Further, in the first embodiment, for example, in the case where excellent flexibility is required for the folded piece portion 2b due to the use of a product in which a hidden slide fastener is used, the connecting member 13 is not provided on the regulating member 11 and the small piece is provided. The respective regulating main body portions 12 can be sewn separately from the folded piece portion 2b without being connected to each other. For example, the flexibility of the folded piece 2b can be further improved by setting the size of each regulating main body 12 in the regulating member 11 in the tape length direction to be shorter.

　なお、本実施例２に係る隠しスライドファスナー２０、及び、後述する実施例３，４に係る隠しスライドファスナー３０，４０では、ファスナーテープの折り返し片部に縫着される規制部材が前述の実施例１における隠しスライドファスナー１０と相違しており、それ以外の構成については実施例１と実質的に同じである。従って、本実施例２、及び、後述する実施例３，４において、前述の実施例１にて説明した部材と同様の構成を有するものについては、同じ符号を用いて表すことによってその説明を省略することとする。 FIG. 6 is a cross-sectional view of a hidden slide fastener according to a second embodiment of the present invention, and FIG. 7 is a perspective view illustrating a regulating member included in the hidden slide fastener.
In the hidden slide fastener 20 according to the second embodiment and the hidden slide fasteners 30 and 40 according to the third and fourth embodiments described later, the restricting member sewn on the folded piece portion of the fastener tape is the above-described embodiment. 1 is different from the hidden slide fastener 10 in FIG. 1, and other configurations are substantially the same as those in the first embodiment. Accordingly, in the second embodiment and the third and fourth embodiments to be described later, those having the same configuration as the members described in the first embodiment are denoted by the same reference numerals and the description thereof is omitted. I decided to.
　本実施例２の隠しスライドファスナー２０は、左右一対のファスナーストリンガー１と、スライダー４とを有しており、前記ファスナーストリンガー１は、左右一対のファスナーテープ２と、各ファスナーテープ２の折り返し片部２ｂの外面に縫着された連続エレメント列３と、同折り返し片部２ｂの内面に縫着糸５を用いて連続エレメント列３とともに縫着された規制部材２１とを備えている。 The hidden slide fastener 20 according to the second embodiment includes a pair of left and right fastener stringers 1 and a slider 4, and the fastener stringer 1 includes a pair of left and right fastener tapes 2 and a folded piece portion of each fastener tape 2. A continuous element row 3 sewn on the outer surface of 2b and a regulating member 21 sewn together with the continuous element row 3 using a sewing thread 5 on the inner surface of the folded piece 2b.
　本実施例２の規制部材２１は、図７に示したように、正面視にて矩形状の小片状に形成された複数の規制本体部２２と、同規制本体部２２をテープ長さ方向に連結する連結部２３とを有している。前記連結部２３は一定の幅寸法を有するフィルム状に形成されており、同連結部２３には、小片状の規制本体部２２がテープ長さ方向に所定の間隔をもって一体成形されているため、各規制本体部２２は連結部２３を介してひとつながりに連結されている。 As shown in FIG. 7, the restricting member 21 of the second embodiment includes a plurality of restricting main body portions 22 formed in a rectangular piece shape in front view, and the restricting main body portion 22 in the tape length direction. And a connecting portion 23 to be connected. The connecting portion 23 is formed in a film shape having a certain width dimension, and a small piece-like regulation main body portion 22 is integrally formed in the connecting portion 23 at a predetermined interval in the tape length direction. The regulation main body portions 22 are connected to each other through a connecting portion 23.
　この場合、規制部材２１の規制本体部２２は、前記実施例１と同様に、左右の連続エレメント列３が噛合したときに、同規制部材２１の一側縁がファスナーテープ２のテープ折曲部２ｃの内面に当接する位置に配されている。また、各規制本体部２２の折り返し片部２ｂに接触する第１面とは反対側の第２面には、縫着糸５を収容する収容溝２２ａがテープ長さ方向に沿って凹設されている。 In this case, the restriction main body 22 of the restriction member 21 has a tape bent portion of the fastener tape 2 at one side edge of the restriction member 21 when the left and right continuous element rows 3 are engaged, as in the first embodiment. It arrange | positions in the position contact | abutted to the inner surface of 2c. In addition, an accommodation groove 22a for accommodating the sewing thread 5 is recessed along the tape length direction on the second surface opposite to the first surface that contacts the folded piece portion 2b of each regulation main body portion 22. ing.
　前記縫着糸５は、連続エレメント列３及び規制部材２１を二重環縫いにより縫着するため、規制部材２１の第２面側を走行する針糸５ａと、同針糸５ａに交絡しながら連続エレメント列３の下脚部６ｃ下面側を走行するルーパ糸５ｂとを有している。 The sewing thread 5 sews the continuous element row 3 and the regulating member 21 by double chain stitching, so that the needle thread 5a traveling on the second surface side of the regulating member 21 is entangled with the needle thread 5a. And a looper yarn 5b that travels on the lower surface side of the lower leg portion 6c of the continuous element row 3.
　従って、前記収容溝２２ａでは、規制部材２１の第２面側を走行する針糸５ａを確実に収容するように、同収容溝２２ａの溝幅は、規制部材２１の第２面側を走行する針糸５ａの走行位置が収容溝２２ａ内に含まれるように設定され、収容溝２２ａの溝深さは、縫着糸５の直径よりも大きくなるように設定されている。 Therefore, in the accommodation groove 22a, the groove width of the accommodation groove 22a travels on the second surface side of the regulation member 21 so as to securely accommodate the needle thread 5a traveling on the second surface side of the regulation member 21. The travel position of the needle thread 5a is set to be included in the accommodation groove 22a, and the groove depth of the accommodation groove 22a is set to be larger than the diameter of the sewing thread 5.
　このような規制本体部２２に収容溝２２ａが形成された規制部材２１を、ファスナーテープ２の折り返し片部２ｂに連続エレメント列３とともに縫着することによって、図６に示したように、規制本体部２２の第２面側を走行する縫着糸５（針糸５ａ）が収容溝２２ａ内に収容されるため、同縫着糸５は、規制部材２１の第２面よりも低い位置に（言い換えると、規制本体部２２の第２面よりも折り返し片部２ｂ側の位置に）配される。 As shown in FIG. 6, the regulation member 21 having the accommodation groove 22 a formed in the regulation body 22 is sewn together with the continuous element row 3 to the folded piece 2 b of the fastener tape 2. Since the sewing thread 5 (needle thread 5a) traveling on the second surface side of the portion 22 is accommodated in the accommodation groove 22a, the sewing thread 5 is positioned at a position lower than the second surface of the regulating member 21 ( In other words, it is arranged at a position closer to the folded piece portion 2b than the second surface of the restriction main body portion 22.
　このような規制部材２１を有する本実施例２の隠しスライドファスナー２０は、前記実施例１の隠しスライドファスナー２０と同様に、左右の連続エレメント列３の噛合時に、左右のテープ折曲部２ｃが互いに付き合わされるとともに、規制部材２１がテープ折曲部２ｃの内面に当接して同テープ折曲部２ｃを押さえることができるため、左右のテープ折曲部２ｃが互いに付き合わされた状態を安定して保持することができる。従って、左右のファスナーテープ２が横引き力を受けて外側に引っ張られても、左右のテープ折曲部２ｃが互いに離間する方向へ移動することを規制して、噛合状態にある左右の連続エレメント列３が隠蔽されている状態を維持することができる。 The hidden slide fastener 20 of the second embodiment having such a regulating member 21 has the left and right tape bent portions 2c when the left and right continuous element rows 3 are engaged, like the hidden slide fastener 20 of the first embodiment. Since the restricting member 21 can abut against the inner surface of the tape bent portion 2c and press the tape bent portion 2c, the state where the left and right tape bent portions 2c are attached to each other can be stabilized. Can be held. Therefore, even if the left and right fastener tapes 2 receive a lateral pulling force and are pulled outward, the left and right tape bent portions 2c are restricted from moving in a direction away from each other, and the left and right continuous elements are in meshing state. The state where the column 3 is concealed can be maintained.
　更に、同隠しスライドファスナー２０は、規制部材２１の第２面側を走行する縫着糸５が収容溝２２ａ内に収容されているため、スライダー４が連続エレメント列３に沿って摺動する際に、その縫着糸５とスライダー４とが互いに干渉することを防止できる。これにより、スライダー４の摺動抵抗が小さくなり、スライダー４をより円滑に摺動させることができるとともに、縫着糸５に糸切れが生じることも効果的に防止することができる。 Further, the hidden slide fastener 20 has the sewing thread 5 running on the second surface side of the regulating member 21 accommodated in the accommodation groove 22a, so that the slider 4 slides along the continuous element row 3. In addition, the sewing thread 5 and the slider 4 can be prevented from interfering with each other. As a result, the sliding resistance of the slider 4 is reduced, the slider 4 can be slid more smoothly, and thread breakage of the sewing thread 5 can be effectively prevented.
　なお、本実施例２の隠しスライドファスナー２０では、図７に示したように、小片状の各規制本体部２２が、一定の幅寸法を有するフィルム状の連結部２３により連結されて折り返し片部２ｂに縫着されている。しかしながら、前記実施例１の変形例にて説明したように、この実施例２においても、例えばファスナーテープ２の折り返し片部２ｂにおける可撓性を高めるために、図８に示したように、幅広部２３ａ’と幅狭部２３ｂ’が交互に配された連結部２３’の幅広部１３ａ’に、小片状の規制本体部２２を一体成形することによって、規制部材２１’を形成することも可能である。また、必要に応じて、小片状の各規制本体部２２を、連結部２３によって連結せずに規制部材を構成することも可能である。 In the hidden slide fastener 20 of the second embodiment, as shown in FIG. 7, each piece-shaped regulation main body portion 22 is connected by a film-like connection portion 23 having a certain width dimension, and the folded piece. It is sewn to the part 2b. However, as described in the modification of the first embodiment, also in this second embodiment, for example, in order to increase flexibility in the folded piece portion 2b of the fastener tape 2, as shown in FIG. The regulating member 21 ′ may be formed by integrally molding the small regulating body 22 into the wide portion 13a ′ of the connecting portion 23 ′ in which the portions 23a ′ and the narrow portions 23b ′ are alternately arranged. Is possible. Moreover, it is also possible to constitute a restricting member without connecting the small piece-like restricting main body portions 22 by the connecting portions 23 as necessary.
　図９は、本発明の実施例３に係る隠しスライドファスナーの断面図であり、図１０は、同隠しスライドファスナーが有する規制部材を示す正面図である。
　本実施例３の隠しスライドファスナー３０が有する規制部材３１は、テープ長さ方向に沿って所定の間隔で配され、正面視にて矩形状を呈する複数の規制本体部３２と、各規制本体部３２の一側縁を連結する玉縁状の連結部３３とを有している。 FIG. 9 is a cross-sectional view of a hidden slide fastener according to a third embodiment of the present invention, and FIG. 10 is a front view showing a regulating member included in the hidden slide fastener.
The restricting member 31 included in the hidden slide fastener 30 of the third embodiment is arranged at predetermined intervals along the tape length direction, and includes a plurality of restricting body portions 32 having a rectangular shape in front view, and the restricting body portions. And a ball-shaped connecting portion 33 that connects one side edges of the two.
　本実施例３における連結部３３は、断面が円形状に形成されており、例えばポリウレタン、シリコーンゴム、熱可塑性エラストマーなどの軟質の合成樹脂を用いて成形されているため、図１０に示したように、規制部材３１を容易に撓ませることができる。従って、同規制部材３１が折り返し片部２ｂに縫着されていても、同折り返し片部２ｂの可撓性が容易に確保されるため、隠しスライドファスナー３０を開閉する際にスライダー４を円滑に摺動させることができる。 The connecting portion 33 in the third embodiment has a circular cross section, and is formed using a soft synthetic resin such as polyurethane, silicone rubber, or thermoplastic elastomer. Further, the restricting member 31 can be easily bent. Therefore, even if the regulating member 31 is sewn to the folded piece 2b, the flexibility of the folded piece 2b is easily ensured, so that the slider 4 can be smoothly moved when opening and closing the hidden slide fastener 30. Can be slid.
　このような規制部材３１が縫着された本実施例３の隠しスライドファスナー３０は、図９に示したように、左右の連続エレメント列３の噛合時に、テープ長さ方向に連続して配された玉縁状の連結部３３がファスナーテープ２のテープ折曲部２ｃの内面に当接して、同テープ折曲部２ｃが離間する方向へ移動することを規制している。これにより、前述の実施例１や実施例２よりも更に安定して左右のテープ折曲部２ｃが付き合わされた状態を保持することができるため、隠しスライドファスナー３０の隠蔽性を向上させることができる。 As shown in FIG. 9, the hidden slide fastener 30 of the third embodiment to which such a regulating member 31 is sewn is continuously arranged in the tape length direction when the left and right continuous element rows 3 are engaged. The rim-shaped connecting portion 33 abuts against the inner surface of the tape bent portion 2c of the fastener tape 2 and restricts the tape bent portion 2c from moving in the direction of separation. Thereby, since the state in which the left and right tape bent portions 2c are attached to each other can be maintained more stably than in the first and second embodiments, the concealability of the hidden slide fastener 30 can be improved. it can.
　また、本実施例３の隠しスライドファスナー３０では、ファスナーテープ２のテープ折曲部２ｃに玉縁状の連結部３３が連続的に当接しているため、テープ折曲部２ｃの形態を安定させて見栄えを良くすることができる。従って、同隠しスライドファスナー３０の意匠性も向上させることができる。 Further, in the hidden slide fastener 30 of the third embodiment, since the bead-shaped connecting portion 33 is continuously in contact with the tape bent portion 2c of the fastener tape 2, the form of the tape bent portion 2c is stabilized. Can improve the appearance. Therefore, the design of the hidden slide fastener 30 can also be improved.
　図１１は、本発明の実施例４に係る隠しスライドファスナーの一方のファスナーストリンガーを示した斜視図である。
　本実施例４の隠しスライドファスナー４０が有する規制部材４１は、一定の幅寸法を有する帯状に形成されている。この規制部材４１は、縫着糸５の二重環縫いによって、ファスナーテープ２の折り返し片部２ｂに連続エレメント列３とともにテープ長さ方向に沿って縫着されている。 FIG. 11 is a perspective view showing one fastener stringer of the hidden slide fastener according to the fourth embodiment of the present invention.
The restricting member 41 included in the hidden slide fastener 40 of the fourth embodiment is formed in a belt shape having a certain width dimension. The regulating member 41 is sewn along the tape length direction together with the continuous element row 3 to the folded piece 2b of the fastener tape 2 by double ring stitching of the sewing thread 5.
　この場合、規制部材４１の材質は特に限定されないが、例えばポリアミド、ポリアセタール、ポリプロピレン、ポリブチレンテレフタレートなどの硬質の合成樹脂を用いることもでき、又は、ポリウレタン、シリコーンゴム、熱可塑性エラストマーなどの軟質の合成樹脂を用いることもできる。例えば、同規制部材４１を硬質樹脂で成形する場合は、前記実施例１～実施例３の規制本体部１２，２２，３２と同様の厚さで成形することによって、ファスナーテープ２のテープ折曲部２ｃが離間する方向に移動することを容易に規制できる。また、同規制部材４１を軟質樹脂で成形する場合は、例えば同規制部材４１の板厚を前記実施例１～実施例３の規制本体部１２，２２，３２よりも厚く設定して剛性を高めることにより、ファスナーテープ２のテープ折曲部２ｃの移動を規制することが可能となる。 In this case, the material of the regulating member 41 is not particularly limited. For example, a hard synthetic resin such as polyamide, polyacetal, polypropylene, and polybutylene terephthalate can be used, or a soft material such as polyurethane, silicone rubber, and thermoplastic elastomer can be used. Synthetic resins can also be used. For example, when the restriction member 41 is molded from a hard resin, the tape bending of the fastener tape 2 is performed by molding the restriction member 41 with the same thickness as the restriction main body portions 12, 22, and 32 of the first to third embodiments. It is possible to easily restrict the movement of the portion 2c in the direction of separation. When the restriction member 41 is molded from a soft resin, for example, the plate thickness of the restriction member 41 is set to be thicker than the restriction main body portions 12, 22, and 32 of the first to third embodiments, thereby increasing the rigidity. This makes it possible to regulate the movement of the tape bending portion 2c of the fastener tape 2.
　このような本実施例４の隠しスライドファスナー４０においても、左右の連続エレメント列３の噛合時に、帯状の規制部材４１の一側縁がファスナーテープ２のテープ折曲部２ｃの内面に連続的に当接して、左右のテープ折曲部２ｃが付き合わされた状態を保持している。従って、左右のファスナーテープ２が横引き力を受けて外側に引っ張られても、テープ折曲部２ｃの移動が規制され、左右の連続エレメント列３が隠蔽されている状態を安定して維持することができる。 Also in the hidden slide fastener 40 of the fourth embodiment as described above, one side edge of the belt-like regulating member 41 is continuously on the inner surface of the tape bent portion 2c of the fastener tape 2 when the left and right continuous element rows 3 are engaged. The left and right tape bent portions 2c are kept in contact with each other. Therefore, even when the left and right fastener tapes 2 receive a lateral pulling force and are pulled outward, the movement of the tape bending portion 2c is restricted and the state where the left and right continuous element rows 3 are concealed is stably maintained. be able to.
　なお、例えば図１２に実施例４の変形例を示したように、帯状の規制部材４１’が折り返し片部２ｂの内面に縫着される隠しスライドファスナー４０’において、その規制部材４１’におけるテープ折曲部２ｃに当接する一側縁とは反対側の他側縁から、所定の長さのスリット４４’が切り込まれていることにより、同規制部材４１’をテープ幅方向（左右方向）に撓み易く形成することができる。 For example, as shown in FIG. 12 showing a modification of the fourth embodiment, in the hidden slide fastener 40 ′ in which the band-shaped regulating member 41 ′ is sewn on the inner surface of the folded piece 2b, the tape on the regulating member 41 ′ A slit 44 'having a predetermined length is cut from the other side edge opposite to the one side edge that contacts the bent portion 2c, so that the regulating member 41' can be moved in the tape width direction (left-right direction). Can be easily bent.
　これにより、スライダー４を摺動させて隠しスライドファスナー４０’を開閉する際に、連続エレメント列３及び規制部材４１’が縫着されたファスナーテープ２の折り返し片部２ｂをスライダー４のエレメント案内路の形状に沿って撓ませながら、スライダー４を円滑に摺動させることができるため、隠しスライドファスナー４０’の操作性を向上させることができる。 Thus, when the slider 4 is slid to open and close the hidden slide fastener 40 ′, the folded piece 2 b of the fastener tape 2 to which the continuous element row 3 and the regulating member 41 ′ are sewn is connected to the element guide path of the slider 4. Since the slider 4 can be smoothly slid while being bent along the shape of the cover, the operability of the hidden slide fastener 40 ′ can be improved.
　また、前述の実施例１～実施例４に示した隠しスライドファスナー１０、１０’、２０、２０’、３０、４０、４０’では、テープ折曲部２ｃの移動を規制する規制部材１１、１１’、２１、２１’、３１、４１、４１’が、縫着糸５によって連続エレメント列３とともに折り返し片部２ｂに縫着されている。しかし、本発明はこれに限定されず、例えば連続エレメント列３を折り返し片部２ｂの外面に縫着した後に、同折り返し片部２ｂの内面に、規制部材を接着又は溶着等によって連続エレメント列３とは別途に取着することも可能である。 Further, in the hidden slide fasteners 10, 10 ′, 20, 20 ′, 30, 40, and 40 ′ shown in the first to fourth embodiments, the regulating members 11 and 11 that regulate the movement of the tape bent portion 2c. ', 21, 21', 31, 41, 41 'are sewn to the folded piece 2b together with the continuous element row 3 by the sewing thread 5. However, the present invention is not limited to this. For example, after the continuous element row 3 is sewn to the outer surface of the folded piece portion 2b, the regulating element is bonded or welded to the inner surface of the folded piece portion 2b. It can also be attached separately.
