　そこで、国際公開２０１１／００４０１６７号（特許文献２）に記載の技術では、ファスナーエレメント間の芯紐の寸法をスライダーのフランジの隙間よりも大きくすることで、ファスナーエレメントの間でスライダーがテープ部材から抜けてしまう可能性を低減した。 Therefore, in the technology described in International Publication No. 2011/0040167 (Patent Document 2), the size of the core string between the fastener elements is made larger than the gap between the flanges of the slider, so that the sliders are separated from the tape members between the fastener elements. Reduced the possibility of falling out.

　しかしながら、特許文献２に記載の技術では、芯紐の寸法を大きくしたので、テープ部材の柔軟性が損なわれると共に、芯紐がスライダーのフランジの隙間から抜けることは低減されても、噛み合ってしまう可能性があった。 However, in the technique described in Patent Document 2, since the size of the core string is increased, the flexibility of the tape member is impaired, and even if the core string is reduced from coming out of the gap of the flange of the slider, it is engaged. There was a possibility.

　本実施形態にて説明するスライドファスナー１０は、図１に示すように、一対のファスナーチェーン１と、スライダー５と、を備える。 The slide fastener 10 described in the present embodiment includes a pair of fastener chains 1 and a slider 5 as shown in FIG.
　ファスナーチェーン１は、左右方向に平行に配置される左右一対のテープ部材２と、左右一対のテープ部材２にそれぞれ所定の間隔をあけて取り付けられる複数の第１エレメント３と、各第１エレメント３の間に取り付けられる第２エレメント４と、を有する。複数の第１エレメント３及び第２エレメント４は、左右一対のテープ部材２にそれぞれ上下方向に独立し、交互に取り付けられてファスナーエレメント列３０を構成する The fastener chain 1 includes a pair of left and right tape members 2 arranged in parallel in the left-right direction, a plurality of first elements 3 attached to the pair of left and right tape members 2 at predetermined intervals, and the first elements 3. 2nd element 4 attached between. The plurality of first elements 3 and second elements 4 are independently attached to the pair of left and right tape members 2 in the vertical direction, and are alternately attached to constitute a fastener element row 30.
　以下の説明にて、図２に示すように、ファスナーチェーン１の長手方向にてファスナーエレメント列３０が設けられる方向を上下方向とし、スライダー５を摺動して左右のファスナーエレメント列３０を噛合させる方向を上方向Ｕ、分離させる方向を下方向Ｄとする。そして、左右方向は、ファスナーチェーン１の面に水平で上下方向に垂直な方向とし、図２における紙面の右方向をＲ、左方向をＬとする。また、図５及び図６に示すように、上下方向および左右方向で規定される面に垂直な方向を表裏方向とし、ファスナーチェーン１のスライダー５の引手が存在する面側を表側Ｈｓとし、その反対面側を裏側Ｂｓとする。 In the following description, as shown in FIG. 2, the direction in which the fastener element row 30 is provided in the longitudinal direction of the fastener chain 1 is the vertical direction, and the slider 5 is slid to engage the left and right fastener element rows 30. The direction is an upward direction U, and the direction of separation is a downward direction D. The left-right direction is a direction horizontal to the surface of the fastener chain 1 and perpendicular to the up-down direction, and the right direction of the paper surface in FIG. Further, as shown in FIGS. 5 and 6, the direction perpendicular to the surface defined by the up and down direction and the left and right direction is the front and back direction, and the surface side where the handle of the slider 5 of the fastener chain 1 exists is the front side Hs, The opposite side is defined as the back side Bs.
　テープ部材２は、テープ主体部２１と、このテープ主体部２１の一側縁に接続し、テープ主体部２１に比べて表裏方向に厚みを有して形成され、複数の第１エレメント３及び第２エレメント４が上下方向に独立して取り付けられるテープ側縁部２２と、を有している。 The tape member 2 is connected to the tape main body 21 and one side edge of the tape main body 21 and is formed to have a thickness in the front and back direction as compared with the tape main body 21. 2 element 4 has tape side edge part 22 to which it attaches independently in the up-and-down direction.
　第１エレメント３は、図５及び図６に示すように、表側部３１と、裏側部３２と、取付部３３と、収容部３４と、係合部３５と、を有する。第１エレメント３は、例えば、ポリアミド、ポリアセタール、ポリプロピレン、ポリプチレンテレフタレート等の合成樹脂を用いて、テープ部材２のテープ側縁部２２に射出成形される。 As shown in FIGS. 5 and 6, the first element 3 includes a front side portion 31, a back side portion 32, an attachment portion 33, a storage portion 34, and an engagement portion 35. The first element 3 is injection-molded on the tape side edge portion 22 of the tape member 2 using a synthetic resin such as polyamide, polyacetal, polypropylene, or polybutylene terephthalate.
　表側部３１は、テープ部材２の表側に配置され、表方向から見て、図７に示すように、左右方向中心線ＨＬを基準として上下対称、且つ上下方向中心線ＶＬを基準として左右対称の略長円形状に形成される部分である。表側部３１は、上下方向及び左右方向から見て、全体的に湾曲した略半球形状に形成されると好ましい。すなわち、上端３１ａ、下端３１ｂ、及び左右端３１ｃ，３１ｄから頂部３１ｅの方向に向かって漸次湾曲する湾曲面によって形成される。 The front side portion 31 is disposed on the front side of the tape member 2 and is vertically symmetric with respect to the center line HL in the horizontal direction and symmetrical with respect to the center line VL in the vertical direction as shown in FIG. 7 when viewed from the front direction. It is a part formed in a substantially oval shape. The front side portion 31 is preferably formed in a substantially hemispherical shape that is curved as a whole when viewed from the vertical direction and the horizontal direction. That is, it is formed by a curved surface that gradually curves from the upper end 31a, the lower end 31b, and the left and right ends 31c, 31d toward the apex 31e.
　なお、表側部３１は、表側から見たときのデザイン性に優れ、角部がなく、スライドファスナー１の柔軟性を確保できる形状であればよく、円形状や楕円形状等の任意の形状とすることが可能である。 In addition, the front side part 31 should just be the shape which is excellent in the design property when it sees from the front side, does not have a corner | angular part, and can ensure the softness | flexibility of the slide fastener 1, and makes it arbitrary shapes, such as circular shape and an ellipse shape. It is possible.
　このように、本実施形態のファスナーチェーン１では、表側部３１が、表方向から見て、左右方向中心線ＨＬを基準として上下対称、且つ上下方向中心線ＶＬを基準として左右対称の略長円形状に形成されるので、スライドファスナー１０の柔軟性が確保されると共に、スライドファスナー１０の意匠性が高められる。また、表側部３１が、上下方向視及び左右方向視において、全体的に湾曲した略半球形状に形成されているため、隣り合う第１エレメント３同士の間隔は、上端部３１ａから頂部３１ｅに向かって漸次大きくなる。したがって、スライドファスナー１０を裏側に凸の状態に湾曲させたとしても、隣り合う第１エレメント３の表側部３１同士がすぐに接触することがないので、スライドファスナー１０の柔軟性が高められる。 As described above, in the fastener chain 1 of the present embodiment, the front side portion 31 has a substantially elliptical shape that is vertically symmetric with respect to the center line HL in the horizontal direction and symmetric with respect to the center line VL in the vertical direction when viewed from the front direction. Since it is formed into a shape, the flexibility of the slide fastener 10 is ensured and the design of the slide fastener 10 is enhanced. In addition, since the front side portion 31 is formed in a substantially hemispherical shape that is curved as a whole in the vertical direction view and the horizontal direction view, the interval between the adjacent first elements 3 is from the upper end portion 31a to the top portion 31e. Gradually increases. Therefore, even if the slide fastener 10 is curved in a convex state on the back side, the front side portions 31 of the adjacent first elements 3 do not immediately come into contact with each other, so that the flexibility of the slide fastener 10 is enhanced.
　なお、極度に裏側に凸の状態に湾曲させた場合には、隣り合う表側部３１の上下湾曲面が接触し、それ以上の屈曲を防止する。このように、表側部３１の表面から上下面の間に形成された湾曲面同士が当接するので、一定以上湾曲させたとしても、ファスナーエレメント列３０の係合を維持できる。 In addition, when it curves to the state which is convex on the back side extremely, the up-and-down curved surface of the adjacent front side part 31 contacts, and prevents further bending. Thus, since the curved surfaces formed between the surface of the front side portion 31 and the upper and lower surfaces contact each other, the engagement of the fastener element rows 30 can be maintained even if the curved surfaces are curved more than a certain amount.
　裏側部３２は、テープ部材２の裏側に配置され、裏方向から見て、左右方向中心線ＨＬを基準として上下対称に形成される部分である。裏側部３２の表面は、上端３２ａ、下端３２ｂ、及び左右端３２ｃ，３２ｄから頂部３２ｅの方向に向かって漸次湾曲する湾曲面によって形成される。なお、頂部３２ｅの一部は、平面であってもよい。 The back side portion 32 is a portion that is disposed on the back side of the tape member 2 and is formed vertically symmetrically with respect to the center line HL in the left-right direction when viewed from the back direction. The surface of the back side portion 32 is formed by a curved surface that gradually curves from the upper end 32a, the lower end 32b, and the left and right ends 32c, 32d toward the top portion 32e. In addition, a part of top part 32e may be a plane.
　図６に示すように、裏側部３２は、基部３２１と、頭部３２２と、首部３２３と、を有する。基部３２１は、表側部３１と共にテープ部材２に取り付けられる取付部３３を形成する部分である。頭部３２２は、表側部３１と共に第２エレメント４を収容する収容部３４を形成する部分である。首部３２３は、基部３２１と頭部３２２との間で上下が凹状に形成され、基部３２１及び頭部３２２よりも幅の狭い部分である。基部３２１、頭部３２２及び首部３２３は、それぞれ湾曲した面で接続されることが好ましい。 As shown in FIG. 6, the back side portion 32 has a base portion 321, a head portion 322, and a neck portion 323. The base portion 321 is a portion that forms an attachment portion 33 attached to the tape member 2 together with the front side portion 31. The head portion 322 is a portion that forms the accommodating portion 34 that accommodates the second element 4 together with the front side portion 31. The neck portion 323 is formed in a concave shape between the base portion 321 and the head portion 322 and is narrower than the base portion 321 and the head portion 322. The base 321, the head 322, and the neck 323 are preferably connected by curved surfaces.
　取付部３３は、表側部３１と裏側部３２のテープ部材２側の境界において上下方向に溝状に形成されている部分である。取付部３３は、テープ側縁部２２を挿通固定し、テープ部材２に第１エレメント３を取り付ける。 The mounting portion 33 is a portion formed in a groove shape in the vertical direction at the boundary between the front side portion 31 and the back side portion 32 on the tape member 2 side. The attachment portion 33 inserts and fixes the tape side edge portion 22 and attaches the first element 3 to the tape member 2.
　収容部３４は、表側部３１と裏側部３２のテープ部材２とは反対側の境界において上下方向に溝状に形成されている部分である。収容部３４は、左右に向かい合うテープ部材２に取り付けられたファスナーエレメント列３０が噛み合う際に、第２エレメント４を収容する。 The accommodating part 34 is a part formed in a groove shape in the vertical direction at the boundary of the front side part 31 and the back side part 32 opposite to the tape member 2. The accommodating portion 34 accommodates the second element 4 when the fastener element row 30 attached to the tape member 2 facing left and right meshes.
　係合部３５は、表側部３１と裏側部３２の上下の境界において、表側部３１の上端３１ａ及び下端３１ｂ及び裏側部３２の上端３２ａ及び下端３２ｂより上下方向に突出する部分である。係合部３５は、収容部３４の上下端から上下方向に徐々に突出する傾斜面３５ａと、傾斜面３５ａから湾曲して接続され、表側部３１の表面及び裏側部３２の首部３２３に接続される係合面３５ｂと、を有する。係合部３５の係合面３５ｂは、左右に向かい合うテープ部材２に取り付けられた第１エレメント３を噛み合わせる際に、上下方向に隣り合う位置関係になる第１エレメント３を互いに係合する。なお、係合部３５は、第１エレメント３の表裏方向の中心を含み、かつ表裏方向において表側部３１の頂部３１ｅと裏側部３２の頂部３２ｅとの間に、所定の幅で形成されることが好ましい。 The engaging portion 35 is a portion that protrudes in the vertical direction from the upper end 31 a and the lower end 31 b of the front side portion 31 and the upper end 32 a and the lower end 32 b of the back side portion 32 at the upper and lower boundaries of the front side portion 31 and the back side portion 32. The engaging portion 35 is connected to an inclined surface 35 a that gradually protrudes in the vertical direction from the upper and lower ends of the accommodating portion 34, and is curvedly connected from the inclined surface 35 a, and is connected to the surface of the front side portion 31 and the neck portion 323 of the back side portion 32. Engaging surface 35b. When engaging the first element 3 attached to the tape member 2 facing left and right, the engaging surface 35b of the engaging portion 35 engages the first elements 3 in the positional relationship adjacent to each other in the vertical direction. The engaging portion 35 includes the center of the first element 3 in the front and back direction, and is formed with a predetermined width between the top portion 31e of the front side portion 31 and the top portion 32e of the back side portion 32 in the front and back direction. Is preferred.
　したがって、スライドファスナー１０を表側又は裏側に凸の状態に湾曲させたとしても、係合部３５は、第１エレメント３の表裏方向の中心付近に形成されているため、表裏方向への変位が抑制され、左右一対の第１エレメント列３０の係合を維持できる。また、隣り合う係合部３５同士の接触を軽減できるため、スライドファスナー１０の柔軟性が高められる。 Therefore, even if the slide fastener 10 is bent in a convex state on the front side or the back side, the engagement portion 35 is formed near the center of the first element 3 in the front and back direction, so that displacement in the front and back direction is suppressed. Thus, the engagement of the pair of left and right first element rows 30 can be maintained. Moreover, since the contact of the adjacent engaging parts 35 can be reduced, the flexibility of the slide fastener 10 is improved.
　第２エレメント４は、上下方向に延びる円筒状の部材であって、上下方向端面と円周面は湾曲して角のないように形成される。第２エレメント４は、上下方向に独立して取り付けられた各第１エレメント３の間で、テープ側縁部２２にそれぞれ取り付けられる。第２エレメント４は、図４に示すように、左右に向かい合うテープ部材２に取り付けられた第１エレメント３を噛み合わせる際に、収容部３４に収容される。本実施形態においては、第２エレメント４の表裏方向の厚みは、収容部３４の表裏方向の間隔に比べて小さく形成され、ファスナーエレメント列３０を噛合させる際に影響を与えないが、例えば、第２エレメント４の厚みを収容部３４の間隔よりも大きく形成し、第２エレメント４を収容部３４内に係合させることで、ファスナーエレメント列３０の噛み合い状態を強固にすることができる。 The second element 4 is a cylindrical member extending in the vertical direction, and the vertical end face and the circumferential surface are curved so that there are no corners. The 2nd element 4 is each attached to the tape side edge part 22 between each 1st element 3 attached independently in the up-down direction. As shown in FIG. 4, the second element 4 is accommodated in the accommodating portion 34 when the first element 3 attached to the tape member 2 facing left and right is meshed. In the present embodiment, the thickness of the second element 4 in the front and back direction is formed smaller than the distance in the front and back direction of the housing portion 34 and does not affect the engagement of the fastener element rows 30. The meshing state of the fastener element row 30 can be strengthened by forming the thickness of the two elements 4 larger than the interval between the accommodating portions 34 and engaging the second element 4 in the accommodating portion 34.
　第２エレメント４は、テープ側縁部２２に取り付けられ、上下方向に延びる筒状の部材であり、収容部３４は、第２エレメント４を収容可能な溝状に形成されるので、エレメント３の噛み合い状態で、ファスナーエレメント列３０を一列に形成することができ、デザイン性を向上させることができる。 The second element 4 is a cylindrical member that is attached to the tape side edge portion 22 and extends in the vertical direction, and the accommodating portion 34 is formed in a groove shape that can accommodate the second element 4. In the meshed state, the fastener element rows 30 can be formed in a single row, and the design can be improved.
　また、本実施形態のファスナーチェーン１によれば、第２エレメント４は、テープ側縁部２２に取り付けられた複数の第１エレメント３の間にそれぞれ取り付けられるので、ファスナーエレメント列３０の噛合状態では、第１エレメント３の収容部３４内に第２エレメント４が収容されており、スライドファスナー１０を表裏方向に凸の状態に湾曲させたとしても、収容部３４と第２エレメント４が接触する。このため、第１エレメント３の収容部３４内にテープ側縁部２２が収容された状態に比べ、ファスナーチェーン１の表折方向の変位を抑制でき、噛み合い状態をさらに強固に保持することが可能となる。 Moreover, according to the fastener chain 1 of this embodiment, since the 2nd element 4 is each attached between the some 1st elements 3 attached to the tape side edge part 22, in the meshing state of the fastener element row | line | column 30 Even if the second element 4 is accommodated in the accommodating portion 34 of the first element 3 and the slide fastener 10 is bent in a convex state in the front and back direction, the accommodating portion 34 and the second element 4 come into contact with each other. For this reason, compared with the state in which the tape side edge portion 22 is accommodated in the accommodating portion 34 of the first element 3, the displacement of the fastener chain 1 in the front folding direction can be suppressed, and the meshing state can be held more firmly. It becomes.
　このように、エレメント３及び第２エレメント４が全体的に丸みを帯びた形状となっている。すなわち、噛み合い状態で、隣り合うエレメント３の頂部３１ｅ，３１ｅ間の距離が芯部（テープ側縁部）２２上での隣り合うエレメント３の上端３１ａと下端３１ｂの間の距離よりも長い。したがって、スライドファスナー１０が表側又は裏側に凸の状態に湾曲された場合、隣り合うエレメント３同士が接触するまでの湾曲できる範囲が大きくなり、スライドファスナー１０の柔軟性を維持することが可能となる。 Thus, the element 3 and the second element 4 have a rounded shape as a whole. That is, in the meshed state, the distance between the top portions 31 e and 31 e of the adjacent elements 3 is longer than the distance between the upper end 31 a and the lower end 31 b of the adjacent elements 3 on the core portion (tape side edge) 22. Therefore, when the slide fastener 10 is bent in a convex state on the front side or the back side, the range that can be bent until the adjacent elements 3 come into contact with each other increases, and the flexibility of the slide fastener 10 can be maintained. .
　また、噛み合い状態が解除された分解状態では、ファスナーチェーン１が表側又は裏側に凸の状態に湾曲された場合、隣り合う第１エレメント３の頂部３１ｅと第２エレメント４の頂部の間の距離が芯部２２上での隣り合う第１エレメント３の端部と第２エレメント４の端部の間の距離よりも長い。したがって、ファスナーチェーン１が表側又は裏側に凸の状態に湾曲された場合、隣り合う第１エレメント３と第２エレメント４が接触するまでの湾曲できる範囲が大きくなり、ファスナーチェーン１の柔軟性を維持することが可能となる。 In the disassembled state in which the meshing state is released, when the fastener chain 1 is curved in a convex state on the front side or the back side, the distance between the top portion 31e of the adjacent first element 3 and the top portion of the second element 4 is It is longer than the distance between the end of the adjacent first element 3 and the end of the second element 4 on the core 22. Therefore, when the fastener chain 1 is bent in a convex state on the front side or the back side, the range that can be bent until the adjacent first element 3 and second element 4 come into contact with each other increases, and the flexibility of the fastener chain 1 is maintained. It becomes possible to do.
　さらに、第１エレメント３と第２エレメント４のテープ主体部２１に取り付けられた部分が、左右方向中心線ＨＬを基準として上下対称で、円弧状に形成されている。したがって、スライダー５が第１エレメント３、第２エレメント４と接触する際、スライダー５のフランジの内面が、第１エレメント３、第２エレメント４の円弧状に形成された曲面に案内されるため、スライダー５の摺動性を向上させることが可能となる。 Furthermore, the portions of the first element 3 and the second element 4 attached to the tape main body 21 are vertically symmetrical with respect to the center line HL in the left-right direction and are formed in an arc shape. Therefore, when the slider 5 comes into contact with the first element 3 and the second element 4, the inner surface of the flange of the slider 5 is guided to the curved surface formed in the arc shape of the first element 3 and the second element 4, The slidability of the slider 5 can be improved.
　また、図２に示すように、第２エレメント４は、左右方向に対する中心線４ｃが、テープ主体部２１の一側縁に形成されたテープ側縁部２２の中心線２２ｃよりも、テープ主体部２１の他側縁側に偏心して配置されるように、設置されることが好ましい。 Further, as shown in FIG. 2, the second element 4 has a tape main portion whose center line 4 c with respect to the left-right direction is more than the center line 22 c of the tape side edge portion 22 formed at one side edge of the tape main portion 21. It is preferably installed so as to be eccentrically arranged on the other side edge side of 21.
　このような構成でテープ部材２に第２エレメント４を設置することで、第２エレメント４とテープ部材２との接触面積が大きくなり、第２エレメント４をテープ部材２に強固に取り付けることができ、スライダー５が第２エレメント４に衝突する際にも、第２エレメント４がテープ部材２から外れることを抑制することが可能となる。 By installing the second element 4 on the tape member 2 with such a configuration, the contact area between the second element 4 and the tape member 2 is increased, and the second element 4 can be firmly attached to the tape member 2. Even when the slider 5 collides with the second element 4, it is possible to prevent the second element 4 from being detached from the tape member 2.
　スライダー５は、図１～図４に示すように、表裏方向に離間して平行配置される上翼板５１及び下翼板５２と、上翼板５１及び下翼板５２の左右両側縁に沿って設けられる左右一対のフランジ５３と、上翼板５１及び下翼板５２を前端部において連結する案内柱５４と、上翼板５１の上面に設けられる引手取付部５５と、引手取付部５５に回動自在に取り付けられる不図示の引手と、を備える。これにより、スライダー５の前部には案内柱５４により分離された左右の肩口５６が形成され、スライダー５の後部には後口５７が形成される。そして、上翼板５１と下翼板５２との間には、左右の肩口５６と後口５７とを連通する略Ｙ字状のファスナーエレメント案内路５８が設けられており、このファスナーエレメント案内路５８は、左右一対のファスナーエレメント列３０を挿通させる通路を構成する。 As shown in FIGS. 1 to 4, the slider 5 extends along the left and right edges of the upper wing plate 51 and the lower wing plate 52, and the upper wing plate 51 and the lower wing plate 52, which are arranged parallel to each other in the front-back direction. A pair of left and right flanges 53, a guide post 54 that connects the upper wing plate 51 and the lower wing plate 52 at the front end, a pull attachment portion 55 provided on the upper surface of the upper wing plate 51, and a pull attachment portion 55. And a pulling handle (not shown) that is rotatably attached. Thus, left and right shoulder openings 56 separated by the guide pillar 54 are formed at the front portion of the slider 5, and a rear opening 57 is formed at the rear portion of the slider 5. Between the upper wing plate 51 and the lower wing plate 52, a substantially Y-shaped fastener element guide path 58 that communicates the left and right shoulder openings 56 and the rear opening 57 is provided. This fastener element guide path 58 constitutes a passage through which the pair of left and right fastener element rows 30 are inserted.
　図２に示すように、本実施形態のファスナーエレメント列３０の第１エレメント３と第２エレメント４の間隔Ｓ１は、スライダー５のフランジ５３の幅Ｗよりも短く設定される。換言すれば、第１エレメント３と第２エレメント４の間隔Ｓ１は、スライダー５のフランジ５３が第１エレメント３と第２エレメント４の間に進入できない長さに設定される。また、第２エレメント４は、第１エレメント３の間隔Ｓ２の中間付近に配置され、第２エレメント４の上下方向における寸法Ｓ３は、第１エレメント３と第２エレメント４の間隔Ｓ１が、スライダー５のフランジ５３の幅Ｗよりも短く設定できるように形成される。 As shown in FIG. 2, the interval S1 between the first element 3 and the second element 4 of the fastener element row 30 of this embodiment is set to be shorter than the width W of the flange 53 of the slider 5. In other words, the distance S <b> 1 between the first element 3 and the second element 4 is set to such a length that the flange 53 of the slider 5 cannot enter between the first element 3 and the second element 4. The second element 4 is arranged near the middle of the interval S2 between the first elements 3, and the dimension S3 of the second element 4 in the vertical direction is determined by the interval S1 between the first element 3 and the second element 4 being the slider 5. The flange 53 is formed so as to be shorter than the width W of the flange 53.
　したがって、スライダー５のフランジ５３が、第１エレメント３と第２エレメント４の間に進入することや、テープ部材２がスライダー５の上下フランジ５３の間の隙間に進入することが抑制される。さらに、第１エレメント３と第２エレメント４が、スライダー５のエレメント案内路５８に挿通される際も、第１エレメント３と第２エレメント４のテープ主体部２１に取付けられた部分が円弧状に形成されているため、スライダー５の肩口５６側の開口部で引っ掛かることがなく、スライダー５の摺動性が確保される。また、第１エレメント３と第２エレメント４に間隔Ｓ１が設けられるため、スライドファスナー１０の柔軟性が更に高められる。 Therefore, the flange 53 of the slider 5 is prevented from entering between the first element 3 and the second element 4 and the tape member 2 is prevented from entering the gap between the upper and lower flanges 53 of the slider 5. Further, when the first element 3 and the second element 4 are inserted through the element guide path 58 of the slider 5, the portions attached to the tape main body 21 of the first element 3 and the second element 4 are arcuate. Since it is formed, the slider 5 is not caught at the opening on the shoulder opening 56 side, and the slidability of the slider 5 is ensured. Moreover, since the space | interval S1 is provided in the 1st element 3 and the 2nd element 4, the softness | flexibility of the slide fastener 10 is further improved.
　加えて、係合部３５の上下方向の長さＬ１は、図７に示すように、左右一対のファスナーエレメント列３０が直線状に噛み合った状態において、互いに隣り合う表側部３１間の隙間の上下方向の長さＬ２より短く設定されている。換言すれば、係合部３５の上下方向の長さＬ１は、隣り合う第１エレメント３の表側部３１の上下端３１ａ，３１ｂに接触しない長さに設定される。また、係合部３５の上下端と隣り合う第１エレメント３の首部３２３との間には隙間Ｓ４が形成される。 In addition, as shown in FIG. 7, the vertical length L1 of the engaging portion 35 is such that the gap between the front side portions 31 adjacent to each other in a state where the pair of left and right fastener element rows 30 are linearly engaged with each other. It is set shorter than the length L2 in the direction. In other words, the vertical length L1 of the engaging portion 35 is set to a length that does not contact the upper and lower ends 31a and 31b of the front side portion 31 of the adjacent first element 3. Further, a gap S4 is formed between the upper and lower ends of the engaging portion 35 and the neck portion 323 of the first element 3 adjacent thereto.
　したがって、頭部３２２の上下面が、首部３２３から頭部３２２の左右方向の外端部に向けて漸次幅狭になる傾斜面によって形成され、係合部３５の上下端と隣り合う第１エレメント３の首部３２３との間には隙間Ｓ４が形成されるので、スライドファスナー１０を左右方向に湾曲させたとしても、隣り合う第１エレメント３同士が干渉し、接触することが抑制されるため、スライドファスナー１０の柔軟性が高められる。 Therefore, the upper and lower surfaces of the head 322 are formed by inclined surfaces that gradually narrow from the neck 323 toward the left and right outer ends of the head 322, and are adjacent to the upper and lower ends of the engaging portion 35. Since the gap S4 is formed between the three neck portions 323, even if the slide fastener 10 is curved in the left-right direction, the adjacent first elements 3 are prevented from interfering with each other, and thus contact with each other. The flexibility of the slide fastener 10 is increased.
　図８は、作動状態のスライドファスナー１０を示す図である。図９は、作動状態のスライドファスナー１０に外力が作用した場合を示す図である。 FIG. 8 is a view showing the slide fastener 10 in an activated state. FIG. 9 is a diagram illustrating a case where an external force is applied to the slide fastener 10 in the activated state.
　スライダー５は、ファスナーチェーン１の長手方向に、ファスナーエレメント列３０に沿って摺動し、ファスナーエレメント列３０を噛合・分離させる。 The slider 5 slides along the fastener element row 30 in the longitudinal direction of the fastener chain 1 to engage and separate the fastener element row 30.
　スライダー５を移動させると、左右一対のファスナーエレメント列３０は、ファスナーエレメント案内路５８を挿通する。この時、外力Ｆが作用し、一方のファスナーチェーン１が、図９に示すように紙面左側に移動したとする。 When the slider 5 is moved, the pair of left and right fastener element rows 30 are inserted through the fastener element guide path 58. At this time, it is assumed that an external force F acts and one fastener chain 1 moves to the left side of the page as shown in FIG.
　このような場合であっても、本実施形態のスライドファスナー１０は、図２に示したように、ファスナーエレメント列３０の第１エレメント３と第２エレメント４の間隔Ｌ１がスライダー５のフランジ５３の幅Ｗよりも短く設定されているので、スライダー５のフランジ５３は、第１エレメント３と第２エレメント４の間に進入することがない。したがって、スライダー５がファスナーチェーン１から外れることが抑制される。また、テープ部材２がスライダー５の上下フランジ５３の間の隙間に進入することもない。すなわち、的確にファスナーエレメント列３０を噛合・分離させることができるファスナーチェーン１及びスライドファスナー１０を提供することが可能となる。 Even in such a case, as shown in FIG. 2, the slide fastener 10 of the present embodiment has a gap L1 between the first element 3 and the second element 4 of the fastener element row 30 of the flange 53 of the slider 5. Since the width is set to be shorter than the width W, the flange 53 of the slider 5 does not enter between the first element 3 and the second element 4. Therefore, the slider 5 is suppressed from coming off the fastener chain 1. Further, the tape member 2 does not enter the gap between the upper and lower flanges 53 of the slider 5. That is, it is possible to provide the fastener chain 1 and the slide fastener 10 that can accurately engage and separate the fastener element row 30.
　次に、第２実施形態について説明する。 Next, a second embodiment will be described.
　図１０は、本発明にかかる第２実施形態のファスナーチェーン１を用いて構成されたスライドファスナー１０を示す斜視図である。図１１は、スライドファスナー１０をテープ部材２に沿って切断した断面図である。図１２は、図１１のＢ－Ｂ線矢視断面図である。図１３は、第２実施形態の一体に形成した第１エレメント３と第２エレメント４を示す図である。 FIG. 10 is a perspective view showing a slide fastener 10 configured by using the fastener chain 1 of the second embodiment according to the present invention.

Other parts are the same as in the first embodiment.
　第２実施形態のファスナーエレメント３’は、図１４における表側部３１の右端３１ｄ及び裏側部３２の右端３２ｄからテープ部材２のテープ側縁部２２に沿って延びるように第２エレメント４を形成する。第２エレメント４は、上下方向に溝状に形成されている第１エレメント３と共通の取付部３３を有する。取付部３３は、テープ側縁部２２を挿通固定し、テープ部材２に第１エレメント３及び一体となった第２エレメント４を取り付ける。 The fastener element 3 ′ of the second embodiment forms the second element 4 so as to extend along the tape side edge 22 of the tape member 2 from the right end 31 d of the front side portion 31 and the right end 32 d of the back side portion 32 in FIG. 14. . The 2nd element 4 has the attaching part 33 common to the 1st element 3 currently formed in groove shape in the up-down direction. The attachment portion 33 inserts and fixes the tape side edge portion 22 and attaches the first element 3 and the integrated second element 4 to the tape member 2.
　図１１に示すように、本実施形態のファスナーエレメント列３０の各ファスナーエレメント３’の間隔Ｓ５は、スライダー５のフランジ５３の幅Ｗよりも短く設定される。換言すれば、各ファスナーエレメント３’の間隔Ｓ５は、スライダー５のフランジ５３がファスナーエレメント３’の間に進入できない長さに設定される。 As shown in FIG. 11, the interval S5 between the fastener elements 3 ′ of the fastener element row 30 of this embodiment is set to be shorter than the width W of the flange 53 of the slider 5. In other words, the interval S5 between the fastener elements 3 'is set to a length that the flange 53 of the slider 5 cannot enter between the fastener elements 3'.
　したがって、スライダー５のフランジ５３は、各ファスナーエレメント３’の間に進入することがない。また、テープ部材２がスライダー５の上下フランジ５３の間の隙間に進入することもない。さらに、ファスナーエレメント３’が、スライダー５のエレメント案内路５８に挿通される時も、肩口５６側の開口部で引っ掛かることがないので、スライダー５の摺動性が確保される。また、各ファスナーエレメント３’に間隔Ｓ５が設けられるため、スライドファスナー１０の柔軟性が更に高められる。 Therefore, the flange 53 of the slider 5 does not enter between the fastener elements 3 '. Further, the tape member 2 does not enter the gap between the upper and lower flanges 53 of the slider 5. Furthermore, even when the fastener element 3 ′ is inserted through the element guide path 58 of the slider 5, the slider 5 is not slid at the opening on the shoulder opening 56 side, so that the slidability of the slider 5 is ensured. Further, since the interval S5 is provided in each fastener element 3 ', the flexibility of the slide fastener 10 is further enhanced.
