　図８は、特許文献１の裏使いスライドファスナーを示す断面図である。図８に示すように、特許文献１に開示された裏使いスライドファスナー１００は、左右一対のファスナーストリンガ１０２，１０２と、左右一対のファスナーストリンガ１０２，１０２を開閉することが可能なスライダー１０１と、を有している。 FIG. 8 is a sectional view showing the reverse slide fastener of Patent Document 1. As shown in FIG. 8, the back-use slide fastener 100 disclosed in Patent Document 1 includes a pair of left and right fastener stringers 102, 102, a slider 101 that can open and close the pair of left and right fastener stringers 102, 102, have.
　スライダー１０１は、スライダー胴体１１０と、引手１２０と、を有している。スライダー胴体１１０は、上翼板１１１と、上翼板１１１と離間して平行に配された下翼板１１２と、これらの上下翼板１１１，１１２の前端部を連結する案内柱（図８には不図示）と、上翼板１１１の表面（上面）に一体形成された門型形状の引手取付柱１１４と、下翼板１１２の後部側の左右両側縁から上翼板１１１に向けて立設した左右のフランジ１１５と、を有している。 The slider 101 has a slider body 110 and a handle 120. The slider fuselage 110 includes an upper wing plate 111, a lower wing plate 112 arranged parallel to and spaced from the upper wing plate 111, and a guide column (see FIG. 8) that connects the front ends of these upper and lower wing plates 111, 112. (not shown), a gate-shaped handle attachment column 114 integrally formed on the surface (upper surface) of the upper wing plate 111, and a handle mounting column 114 extending from the left and right edges of the rear side of the lower wing plate 112 toward the upper wing plate 111. The left and right flanges 115 are provided.
　左右一対のファスナーストリンガ１０２，１０２は、コイル状のエレメント列１０３に芯紐１０６を挿通したものを、左右一対のファスナーテープ１０４、１０４の相対するテープ側縁部に縫着糸１０５で縫着することによって形成されている。 The left and right pair of fastener stringers 102, 102 are made by inserting a core string 106 through a coiled element row 103, and sewing it to the opposing tape side edges of the left and right pair of fastener tapes 104, 104 with a sewing thread 105. It is formed by

　通常、裏使いスライドファスナーには、左右一対のファスナーテープの間に隙間（所謂、中仕切部）が形成される。実際、図８に示した特許文献１の裏使いスライドファスナー１００においても、左右一対のファスナーテープ１０４，１０４の間に隙間Ｓが形成される。 Normally, in reverse slide fasteners, a gap (so-called middle partition) is formed between a pair of left and right fastener tapes. In fact, also in the reverse slide fastener 100 of Patent Document 1 shown in FIG. 8, a gap S is formed between the pair of left and right fastener tapes 104, 104.
　したがって、左右一対のファスナーテープ１０４，１０４に互いに離れる方向の外力（所謂、横引き）が作用した場合に、使用者が裏使いスライドファスナー１００を表面側（図８の上側）から見た時、隙間Ｓを介してエレメント列１０３が視認され得る。このようなエレメント列１０３の隠蔽性の低下は、裏使いスライドファスナー１００が用いられる物品、特にカーシート、鞄、家具等の美観が重視される物品、のデザイン性を悪化させる点で好ましくない。 Therefore, when an external force (so-called lateral pulling) is applied to the pair of left and right fastener tapes 104, 104 in the direction of separating them from each other, when the user views the back-use slide fastener 100 from the front side (upper side of FIG. 8), The element row 103 can be visually recognized through the gap S. Such a decrease in the concealability of the element array 103 is undesirable in that it deteriorates the design of articles in which the reverse slide fastener 100 is used, particularly articles for which aesthetics are important, such as car seats, bags, and furniture.
　本発明は、以上のような問題点に鑑みてなされたものであり、その目的は、エレメント列の隠蔽性に優れ、ひいては外観に優れた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-mentioned problems, and its purpose is to provide a slide fastener that has excellent concealment of element rows and, in turn, excellent appearance.

　第１及び第２ファスナーテープ１０，２０は、ポリエステル糸等からなる織物又は編物であり、柔軟性に優れる。なお、第１及び第２ファスナーテープ１０，２０は、不織布であってもよい The first and second fastener tapes 10 and 20 are woven or knitted fabrics made of polyester yarn or the like, and have excellent flexibility. Note that the first and second fastener tapes 10 and 20 may be made of nonwoven fabric.
　スライダー４０は、左右一対の第１及び第２エレメント列５０，６０を噛合及び分離させる。スライダー４０は、胴体４１と、胴体４１の表面に設けられる引手取付部４２と、引手取付部４２に取り付けられる引手４３と、を備える。そして、スライダー４０を上方に移動することで、図２に示すように左右一対の第１及び第２エレメント列５０，６０が噛合し、スライダー４０を下方に移動することで、図３に示すように左右一対の第１及び第２エレメント列５０，６０が分離する。なお、スライドファスナー１は、図示しない上止部や下止部を備えてもよい。また、下止部に代えて、箱棒及び箱体を有する開き具が設けられても良い。 The slider 40 engages and separates the pair of left and right first and second element rows 50 and 60. The slider 40 includes a body 41, a handle attachment part 42 provided on the surface of the body 41, and a handle 43 attached to the handle attachment part 42. By moving the slider 40 upward, the pair of left and right first and second element rows 50 and 60 engage with each other as shown in FIG. 2, and by moving the slider 40 downward, as shown in FIG. A pair of left and right first and second element rows 50 and 60 are separated. In addition, the slide fastener 1 may be provided with a top stop part and a bottom stop part which are not shown. Furthermore, instead of the bottom stop, an opening tool having a box bar and a box body may be provided.
　第１及び第２エレメント列５０，６０は、合成樹脂製のモノフィラメントを一定方向に巻回すことにより形成されるコイル状のファスナーエレメント列であり、複数のエレメント３１を有している。そして、第１及び第２エレメント列５０，６０は、複数のエレメント３１の内部に芯紐３２が挿通され、二重環縫いされる縫糸３３によって第１ファスナーテープ１０の幅方向一端部１０ａの裏面１１及び第２ファスナーテープ２０の幅方向一端部２０ａの裏面２１に縫い付けられる。また、モノフィラメントの合成樹脂材料としては、ポリエステル及びナイロンなどを挙げることができる。 The first and second element rows 50 and 60 are coil-shaped fastener element rows formed by winding a synthetic resin monofilament in a certain direction, and have a plurality of elements 31. The first and second element rows 50 and 60 are formed by inserting a core string 32 into the inside of the plurality of elements 31 and sewing threads 33 that are double chain stitched to form the back surface of the first end 10a in the width direction of the first zipper tape 10. 11 and the back surface 21 of the widthwise one end 20a of the second fastener tape 20. Furthermore, examples of the synthetic resin material for the monofilament include polyester and nylon.
　エレメント３１は、相手方のエレメント３１と噛合・分離する噛合頭部３１ａと、噛合頭部３１ａの表側端部から幅方向他端側に延び、第１及び第２ファスナーテープ１０，２０と接触する第１脚部３１ｂと、噛合頭部３１ａの裏側端部から幅方向他端側に延び、第１及び第２ファスナーテープ１０，２０と非接触である第２脚部３１ｃと、第１脚部３１ｂの幅方向外端部と隣り合うエレメント３１の第２脚部３１ｃの幅方向他端部とを連結する連結部３１ｄと、を備える。したがって、第１脚部３１ｂ及び第２脚部３１ｃは、噛合頭部３１ａから突出し平行に延びるように形成されている。 The element 31 includes a mating head 31a that meshes with and separates from the mating element 31, and a mesh head 31a that extends from the front end of the mating head 31a to the other end in the width direction and contacts the first and second fastener tapes 10 and 20. one leg portion 31b, a second leg portion 31c extending from the back side end of the engaging head 31a to the other end in the width direction and not in contact with the first and second fastener tapes 10, 20, and the first leg portion 31b. and a connecting portion 31d that connects the outer end in the width direction and the other end in the width direction of the second leg portion 31c of the adjacent element 31. Therefore, the first leg 31b and the second leg 31c are formed to protrude from the engaging head 31a and extend in parallel.
　図２には、第１及び第２エレメント列５０，６０の噛合中心Ｏが示されている。この噛合中心Ｏは、エレメント３１，３１同士が噛み合った際の中心位置であり、スライドファスナー１の幅方向中心に一致する。図３には、第１及び第２エレメント列５０，６０を噛合した場合に噛合中心Ｏとなる位置が、Ｏ１及びＯ２で示されている。位置Ｏ１，Ｏ２はエレメント３１の噛合頭部３１ａよりも幅方向他端側に位置する。 FIG. 2 shows the meshing center O of the first and second element rows 50 and 60. This meshing center O is the center position when the elements 31, 31 are meshed with each other, and coincides with the widthwise center of the slide fastener 1. In FIG. 3, the positions that become the center of engagement O when the first and second element rows 50 and 60 are engaged are indicated by O1 and O2. Positions O1 and O2 are located closer to the other end in the width direction than the engaging head 31a of the element 31.
　図３に示すように、第１及び第２エレメント列５０，６０が分離した状態では、第１ファスナーテープ１０の幅方向一端部１０ａと第２ファスナーテープ２０の幅方向一端部２０ａとは、互いに幅方向に離間している。 As shown in FIG. 3, when the first and second element rows 50 and 60 are separated, one end 10a of the first fastener tape 10 in the width direction and one end 20a of the second fastener tape 20 in the width direction are mutually connected. They are spaced apart in the width direction.
　なお、図１の上部には、第１及び第２エレメント列５０，６０が分離した状態で、第１ファスナーテープ１０の幅方向一端部１０ａと第２ファスナーテープ２０の幅方向一端部２０ａとが、山なりに座屈した形状で示されているが、これは、第１及び第２エレメント列５０，６０が噛合した状態で一定期間経過した後にこれらを分離した場合に、座屈状態の癖が残存することを示している。第１及び第２エレメント列５０，６０を分離した状態で一定期間経過すると、座屈の癖が解消され、第１ファスナーテープ１０の幅方向一端部１０ａと第２ファスナーテープ２０の幅方向一端部２０ａとはそれぞれ、図３に示すような略平面形状となることもある。 In the upper part of FIG. 1, one end 10a of the first fastener tape 10 in the width direction and one end 20a of the second fastener tape 20 in the width direction are shown in a state where the first and second element rows 50, 60 are separated. , the shape is buckled like a mountain, but this is due to the habit of buckling when the first and second element rows 50 and 60 are meshed and separated after a certain period of time. It shows that there remains. After a certain period of time has passed with the first and second element rows 50 and 60 separated, the buckling habit is eliminated, and one widthwise end 10a of the first fastener tape 10 and one widthwise end of the second fastener tape 20 20a may each have a substantially planar shape as shown in FIG.
　図３に示すように、第１及び第２エレメント列５０，６０が分離している状態において、第１ファスナーテープ１０の幅方向一端部１０ａは、第１及び第２エレメント列５０，６０の噛合中心Ｏとなる位置Ｏ１よりも第２ファスナーテープ２０側（幅方向一端側）に延在し、且つ、第２ファスナーテープ２０の幅方向一端部２０ａは、噛合中心Ｏとなる位置Ｏ２よりも第１ファスナーテープ１０側（幅方向一端側）に延在する。すなわち、図２に示すように第１及び第２エレメント列５０，６０を噛合させたときに、第１及び第２ファスナーテープ１０，２０が噛合中心Ｏに重なるように設計される。このように第１及び第２ファスナーテープ１０，２０と第１及び第２エレメント列５０，６０とを配置することで、後述するように第１及び第２エレメント列５０，６０を噛合させた際に、第１及び第２ファスナーテープ１０，２０とが山なりに座屈して互いに密着させることができる。 As shown in FIG. 3, in a state where the first and second element rows 50 and 60 are separated, one widthwise end 10a of the first fastener tape 10 engages the first and second element rows 50 and 60. It extends to the second fastener tape 20 side (one end side in the width direction) from the position O1 which is the center O, and the one end 20a in the width direction of the second fastener tape 20 is further away from the position O2 which is the engagement center O. 1 extends toward the fastener tape 10 side (one end side in the width direction). That is, the design is such that the first and second fastener tapes 10 and 20 overlap with the meshing center O when the first and second element rows 50 and 60 are meshed as shown in FIG. By arranging the first and second fastener tapes 10 and 20 and the first and second element rows 50 and 60 in this way, when the first and second element rows 50 and 60 are engaged with each other as described later, In addition, the first and second fastener tapes 10 and 20 can be buckled in a mountainous manner and brought into close contact with each other.
　より詳細には、第１及び第２エレメント列５０，６０が分離している状態においては、第１ファスナーテープ１０の幅方向一端面１０ｂが、噛合中心Ｏとなる位置Ｏ１よりも第２ファスナーテープ２０側（幅方向一端側）に配置され、第２ファスナーテープ２０の幅方向一端面２０ｂが、噛合中心Ｏとなる位置Ｏ２よりも第１ファスナーテープ１０側（幅方向一端側）に配置される。 More specifically, in a state where the first and second element rows 50 and 60 are separated, one end surface 10b in the width direction of the first fastener tape 10 is closer to the second fastener tape than the position O1 which is the engagement center O. 20 side (one end side in the width direction), and one end surface 20b in the width direction of the second fastener tape 20 is arranged on the first fastener tape 10 side (one end side in the width direction) than the position O2 which is the engagement center O. .
　第１ファスナーテープ１０の幅方向一端面１０ｂは、幅方向においてエレメント３１の噛合頭部３１ａの少なくとも一部と重なる位置に配置されてもよく、幅方向において噛合頭部３１ａの幅方向一端面３１ｅ（すなわち第１エレメント列５０の幅方向一端面）と同一平面Ｓ１上に配置されてもよく、噛合頭部３１ａよりも第２ファスナーテープ２０側に配置されていてもよい。図２の例では、第１ファスナーテープ１０の幅方向一端面１０ｂは、幅方向において第１エレメント列５０の幅方向一端面と同一平面Ｓ１上に配置されている。 The one end surface 10b in the width direction of the first fastener tape 10 may be arranged at a position overlapping at least a part of the engaging head 31a of the element 31 in the width direction, and the one end surface 31e in the width direction of the engaging head 31a in the width direction. (that is, one end surface in the width direction of the first element row 50) may be arranged on the same plane S1, or may be arranged closer to the second fastener tape 20 than the engaging head 31a. In the example of FIG. 2, one end surface 10b in the width direction of the first fastener tape 10 is arranged on the same plane S1 as one end surface in the width direction of the first element row 50 in the width direction.
　第２ファスナーテープ２０の幅方向一端面２０ｂは、幅方向においてエレメント３１の噛合頭部３１ａの少なくとも一部と重なる位置に配置されてもよく、幅方向において噛合頭部３１ａの幅方向一端面３１ｆ（すなわち第２エレメント列６０の幅方向一端面）と同一平面Ｓ２上に配置されてもよく、噛合頭部３１ａよりも第１ファスナーテープ１０側に配置されていてもよい。図２の例では、第２ファスナーテープ２０の幅方向一端面２０ｂは、幅方向において第２エレメント列６０の幅方向一端面と同一平面Ｓ２上に配置されている。 One end surface 20b in the width direction of the second fastener tape 20 may be arranged at a position overlapping at least a portion of the engaging head 31a of the element 31 in the width direction, and one end surface 31f in the width direction of the engaging head 31a in the width direction. (that is, one end surface in the width direction of the second element row 60) may be arranged on the same plane S2, or may be arranged closer to the first fastener tape 10 than the engaging head 31a. In the example of FIG. 2, one end surface 20b in the width direction of the second fastener tape 20 is arranged on the same plane S2 as one end surface in the width direction of the second element row 60 in the width direction.
　このように、第１及び第２エレメント列５０，６０が分離している状態において、第１ファスナーテープ１０の幅方向一端面１０ｂ及び第１エレメント列５０の幅方向一端面とを同一平面Ｓ１上に配置し、第２ファスナーテープ２０の幅方向一端面２０ｂと第２エレメント列６０の幅方向一端面を同一平面Ｓ２上に配置することで、後述するように第１及び第２エレメント列５０，６０を噛合させた際に、より確実に、第１及び第２ファスナーテープ１０，２０とが山なりに座屈して互いに密着させることができる。これは、第１及び第２ファスナーテープ１０，２０の幅方向一端部１０ａ，２０ａが第１及び第２エレメント列５０，６０同士の噛み合いを妨げず、第１及び第２ファスナーテープ１０，２０同士の圧着が破綻し難い配置関係であるためである。なお、「同一平面上に配置」とは、必ずしもぴったり同一平面上に配置されている必要はなく、噛合頭部３１ａのテーパを考慮して、第１及び第２ファスナーテープ１０，２０の幅方向一端面１０ｂ，２０ｂが噛合頭部３１ａのテーパの始点からテーパの終点までの範囲と一致する範囲である略同一平面上のものも含まれる。 In this manner, in a state where the first and second element rows 50 and 60 are separated, one end surface 10b in the width direction of the first fastener tape 10 and one end surface in the width direction of the first element row 50 are placed on the same plane S1. By arranging one widthwise end surface 20b of the second fastener tape 20 and the widthwise one end surface of the second element row 60 on the same plane S2, the first and second element rows 50, When the fastener tapes 60 are engaged with each other, the first and second fastener tapes 10 and 20 can be buckled in a mountainous manner and brought into close contact with each other. This is because the one end portions 10a, 20a in the width direction of the first and second fastener tapes 10, 20 do not prevent the first and second element rows 50, 60 from interlocking with each other, and the first and second fastener tapes 10, 20 do not interfere with each other. This is because the arrangement relationship makes it difficult for the crimping to fail. Note that "arranged on the same plane" does not necessarily mean that they are arranged exactly on the same plane, but in the width direction of the first and second fastener tapes 10 and 20, taking into consideration the taper of the engaging head 31a. It also includes one in which the end surfaces 10b and 20b are substantially coplanar in a range that coincides with the range from the start point of the taper to the end point of the taper of the engaging head 31a.
　図３に示すような第１及び第２エレメント列５０，６０が分離した状態から、スライダー４０を上方に移動することで、図２に示すように第１及び第２エレメント列５０，６０が噛合する。この際、第１ファスナーテープ１０の幅方向一端部１０ａが第１及び第２エレメント列５０，６０の噛合中心Ｏとなる位置Ｏ１よりも第２ファスナーテープ２０側（幅方向一端側）に延在し、且つ、第２ファスナーテープ２０の幅方向一端部２０ａが噛合中心Ｏとなる位置Ｏ２よりも第１ファスナーテープ１０側（幅方向一端側）に延在しているので、幅方向一端部１０ａと幅方向一端部２０ａとは、互いに幅方向に押し合って変形し、表側に凸である山なりに座屈して互いに密着する。なお、この際に、図２に示すように第１及び第２ファスナーテープ１０，２０に縫い付けられた縫糸３３であって、かつ第１及び第２ファスナーテープ１０，２０の幅方向一端部１０ａ，２０ａ側の縫糸３３が、第１及び第２ファスナーテープ１０，２０の座屈に伴って若干伸びて浮き上がることもある。 By moving the slider 40 upward from the state where the first and second element rows 50 and 60 are separated as shown in FIG. 3, the first and second element rows 50 and 60 are brought into engagement as shown in FIG. do. At this time, one end 10a in the width direction of the first fastener tape 10 extends toward the second fastener tape 20 side (one end in the width direction) from the position O1, which is the engagement center O of the first and second element rows 50, 60. In addition, since the one end 20a in the width direction of the second fastener tape 20 extends toward the first fastener tape 10 (one end in the width direction) than the position O2 where the engagement center O is, the one end 20a in the width direction and the one widthwise end portion 20a are pressed against each other in the width direction and deformed, buckled in a convex shape on the front side, and come into close contact with each other. In addition, at this time, as shown in FIG. , 20a side may stretch a little and float up as the first and second fastener tapes 10 and 20 buckle.
　このように、第１及び第２エレメント列５０，６０を互いに噛み合わせた際に、第１及び第２ファスナーテープ１０，２０が互いに密着するので、従来の裏使いスライドファスナーのように、第１及び第２ファスナーテープ１０，２０の間に隙間（いわゆる中仕切部）が形成されることはない。したがって、使用者がスライドファスナー１を表側から見た時に、第１及び第２エレメント列５０，６０が視認されず、外観に優れる。このようなスライドファスナー１は、特に、カーシート、鞄、家具等の美観が重視される物品に好適である。 In this way, when the first and second element rows 50 and 60 are engaged with each other, the first and second fastener tapes 10 and 20 come into close contact with each other, so that the first And no gap (so-called partition part) is formed between the second fastener tapes 10 and 20. Therefore, when the user views the slide fastener 1 from the front side, the first and second element rows 50 and 60 are not visible, resulting in an excellent appearance. Such a slide fastener 1 is particularly suitable for articles where aesthetics are important, such as car seats, bags, and furniture.
　また、第１及び第２ファスナーテープ１０，２０は山なりに座屈して互いに密着するので、第１及び第２ファスナーテープ１０，２０に互いに離れる方向の力（いわゆる横引き）が作用した場合であっても、エレメント３１，３１同士の噛み合いギャップが打ち消される範囲において、座屈度合いが多少弱まるだけで互いの密着状態は維持されるので、スライドファスナー１の良好な外観が保たれる。 In addition, since the first and second fastener tapes 10 and 20 buckle in a mountainous manner and come into close contact with each other, when a force in a direction that separates the first and second fastener tapes 10 and 20 from each other is applied (so-called lateral pulling), Even if the meshing gap between the elements 31 and 31 is canceled out, the degree of buckling is only slightly weakened and the state of close contact with each other is maintained, so that the slide fastener 1 maintains a good appearance.
　なお、第１及び第２ファスナーテープ１０，２０に、撥水剤を付着させても構わない。撥水剤を付着させることで、スライドファスナー１に撥水性能を付与することができる。上記の撥水剤として、例えば、フッ素系化合物、シリコーン系化合物、アクリル系撥水剤、シリコーン複合系撥水剤、パラフィン系化合物、エチレン尿素系化合物、ジルコニウム系化合物、脂肪酸アミド系化合物、メチロールアミド系化合物、アルキル尿素型、脂肪酸アミド型等の撥水剤を用いることができる。 Note that a water repellent agent may be attached to the first and second fastener tapes 10 and 20. By attaching a water repellent agent, water repellency can be imparted to the slide fastener 1. Examples of the above water repellents include fluorine compounds, silicone compounds, acrylic water repellents, silicone composite water repellents, paraffin compounds, ethylene urea compounds, zirconium compounds, fatty acid amide compounds, and methylolamide. A water repellent such as a type compound, an alkyl urea type, or a fatty acid amide type can be used.
　撥水剤を第１及び第２ファスナーテープ１０，２０に付着する工程は、任意のものが適用できるが、例えば、図示せぬガイドローラーの周面に沿って巻き回してファスナーストリンガ３，５をガイドし、撥水剤を満たした容器内に連続的に通すことにより、撥水剤を浸漬させてもよい。この処理では、ファスナーストリンガ３，５を構成する第１及び第２ファスナーテープ１０，２０、第１及び第２エレメント列５０，６０、芯紐３２、縫糸３３の全面に、効率良く撥水剤が付与される。次に、ファスナーストリンガ３，５を容器内から引き上げて、連続的に乾燥室に通すことによって、先ずファスナーストリンガ３，５の全面に付与した撥水剤を乾燥させる。その後、撥水剤の乾燥が終了したファスナーストリンガ３，５を更に連続的に熱処理室に通すことによって、乾燥した撥水剤に熱処理を行う。この熱処理で、第１及び第２ファスナーテープ１０，２０、第１及び第２エレメント列５０，６０、芯紐３２、縫糸３３のすべての基材と撥水剤の間で融着、付着処理がなされる。 Any process can be applied to the process of attaching the water repellent to the first and second fastener tapes 10 and 20, but for example, the process of attaching the water repellent to the first and second fastener tapes 10 and 20 can be performed by winding the water repellent along the circumferential surface of a guide roller (not shown) to attach the fastener stringers 3 and 5. The water repellent may be immersed by guiding and continuously passing it through a container filled with the water repellent. In this process, the water repellent agent is efficiently applied to the entire surfaces of the first and second fastener tapes 10 and 20, the first and second element rows 50 and 60, the core cord 32, and the sewing thread 33 that constitute the fastener stringers 3 and 5. Granted. Next, the water repellent applied to the entire surface of the fastener stringers 3, 5 is first dried by pulling the fastener stringers 3, 5 out of the container and passing them continuously through a drying chamber. Thereafter, the fastener stringers 3 and 5, on which the water repellent has been dried, are further continuously passed through a heat treatment chamber, thereby subjecting the dried water repellent to heat treatment. This heat treatment causes fusion and adhesion between all base materials of the first and second fastener tapes 10, 20, first and second element rows 50, 60, core string 32, and sewing thread 33 and the water repellent agent. It will be done.
　このように、第１及び第２ファスナーテープ１０，２０に撥水処理が施されている場合、スライドファスナー１を撥水ファスナーとして利用できる。特に、本実施形態では、第１及び第２エレメント列５０，６０を互いに噛み合わせた際に第１及び第２ファスナーテープ１０，２０が山なりに座屈して互いに密着するので、第１及び第２ファスナーテープ１０，２０の間に隙間（中仕切部）が形成されることはなく、従来技術のように中仕切部から液体が進入することが抑制される。 In this way, when the first and second fastener tapes 10 and 20 are subjected to water-repellent treatment, the slide fastener 1 can be used as a water-repellent fastener. In particular, in this embodiment, when the first and second element rows 50 and 60 are engaged with each other, the first and second fastener tapes 10 and 20 buckle in a mountain shape and come into close contact with each other. A gap (inner partition) is not formed between the two fastener tapes 10 and 20, and liquid is prevented from entering from the inner partition as in the prior art.
　また、図２に示すように、第１及び第２エレメント列５０，６０を互いに噛み合わせた際に、第１及び第２ファスナーテープ１０，２０の幅方向一端面１０ｂ及び幅方向一端面２０ｂは、エレメント３１側（裏側）を向き、第１及び第２エレメント列５０，６０に当接する。また、第１ファスナーテープ１０の幅方向一端部１０ａの表面１３と、第２ファスナーテープ２０の幅方向一端部２０ａの表面２３とが、噛合中心Ｏ上で互いに密着する。このように、第１及び第２ファスナーテープ１０，２０の幅方向一端部１０ａ，２０ａの表面１３，２３同士が密着するので、裏面１１，２１同士を密着させた場合（幅方向一端部１０ａ，２０ａを本実施形態とは逆向きに座屈させた場合）に比べて、スライドファスナー１の厚さを抑えるとともに、スライダー４０の摺動抵抗を軽減できる。また、仮に裏面１１，２１同士を密着させた場合には、第１及び第２ファスナーテープ１０，２０の幅方向一端面１０ｂ，２０ｂが表側を向き、テープエッジである幅方向一端部１０ａ，２０ａが表面に向かって凸状となるため、表面の肌触りが悪化する。 Further, as shown in FIG. 2, when the first and second element rows 50 and 60 are engaged with each other, one end surface 10b in the width direction and one end surface 20b in the width direction of the first and second fastener tapes 10 and 20 are , facing the element 31 side (back side) and abuts on the first and second element rows 50 and 60. Further, the surface 13 of the first end 10a in the width direction of the first fastener tape 10 and the surface 23 of the end 20a in the width direction of the second fastener tape 20 are in close contact with each other on the meshing center O. In this way, since the front surfaces 13 and 23 of the widthwise one ends 10a and 20a of the first and second fastener tapes 10 and 20 are in close contact with each other, when the back surfaces 11 and 21 are brought into close contact with each other (widthwise one end 10a, 20a is buckled in the opposite direction to that of the present embodiment), the thickness of the slide fastener 1 can be suppressed and the sliding resistance of the slider 40 can be reduced. In addition, if the back surfaces 11 and 21 are brought into close contact with each other, one end surface 10b and 20b in the width direction of the first and second fastener tapes 10 and 20 faces the front side, and one end surface 10a and 20a in the width direction which is the tape edge Since the surface becomes convex toward the surface, the texture of the surface deteriorates.
　また、図２に示すように、第１及び第２エレメント列５０，６０を互いに噛み合わせた際に、第１及び第２ファスナーテープ１０，２０の幅方向一端面１０ｂ及び幅方向一端面２０ｂの裏面１１，２１と、第１及び第２エレメント列５０，６０（エレメント３１）とは、表裏方向に離間し、両者の間にはそれぞれ第１及び第２空間Ｔ１，Ｔ２が画成される。 Further, as shown in FIG. 2, when the first and second element rows 50 and 60 are engaged with each other, one end surface 10b in the width direction and one end surface 20b in the width direction of the first and second fastener tapes 10 and 20 are The back surfaces 11 and 21 and the first and second element rows 50 and 60 (element 31) are spaced apart from each other in the front and back direction, and first and second spaces T1 and T2 are defined between them, respectively.
　このように、第１及び第２空間Ｔ１，Ｔ２が設けられることで，スライダー４０で第１及び第２エレメント列５０，６０を組み合わせた際、第１及び第２ファスナーテープ１０，２０を容易に座屈させることができる。また、第１及び第２空間Ｔ１，Ｔ２が大きいほど、第１及び第２ファスナーテープ１０，２０の幅方向一端部１０ａ及び幅方向一端部２０ａの表面１３，２３同士の圧着面積が大きくなり、第１及び第２ファスナーテープ１０，２０の間の隙間（中仕切部）の発生が抑制され、外観の向上や撥水性・耐水性の向上に寄与できる。さらに、第１及び第２ファスナーテープ１０，２０同士の圧着の破綻がしにくくなり、形状が維持されやすい。 Thus, by providing the first and second spaces T1 and T2, when the first and second element rows 50 and 60 are combined with the slider 40, the first and second fastener tapes 10 and 20 can be easily attached. Can be buckled. Moreover, the larger the first and second spaces T1 and T2, the larger the crimping area between the surfaces 13 and 23 of the one widthwise end 10a and the widthwise one end 20a of the first and second fastener tapes 10 and 20, The generation of gaps (partitions) between the first and second fastener tapes 10 and 20 is suppressed, contributing to improved appearance and improved water repellency and water resistance. Furthermore, the crimping between the first and second fastener tapes 10 and 20 is less likely to break down, and the shape is easily maintained.
　また、上述したように、第１及び第２ファスナーテープ１０，２０は織物又は編物であり柔軟性に優れるので、第１及び第２エレメント列５０，６０を互いに噛み合わせた際に、第１及び第２ファスナーテープ１０，２０の密着性を高めることができる。また、第１及び第２ファスナーテープ１０，２０の座屈状態を保持することができる。したがって、第１及び第２ファスナーテープ１０，２０の間の隙間（中仕切部）の発生が抑制され、外観の向上や撥水性・耐水性の向上に寄与できる。なお、仮に、第１及び第２ファスナーテープ１０，２０が樹脂等によって成形された場合、座屈形状の形成及び維持が困難である。 Furthermore, as described above, the first and second fastener tapes 10 and 20 are made of woven or knitted fabrics and have excellent flexibility, so when the first and second element rows 50 and 60 are interlocked with each other, the first and second fastener tapes 10 and 20 are The adhesion between the second fastener tapes 10 and 20 can be improved. Moreover, the buckled state of the first and second fastener tapes 10 and 20 can be maintained. Therefore, generation of a gap (partition portion) between the first and second fastener tapes 10 and 20 is suppressed, contributing to improved appearance and improved water repellency and water resistance. In addition, if the first and second fastener tapes 10 and 20 were molded from resin or the like, it would be difficult to form and maintain a buckled shape.
　図４は、第１実施形態の変形例に係るスライドファスナーの要部断面図であり、第１及び第２エレメント列を噛合した状態を示す図である。図３の例においては、図２の例に比べて、第１ファスナーテープ１０の幅方向一端部１０ａ及び第２ファスナーテープ２０の幅方向一端部２０ａの座屈度合いが強められており、第１ファスナーテープ１０の幅方向一端部１０ａの表面１３と第２ファスナーテープ２０の幅方向一端部２０ａの表面２３との圧着面積が増加している。このように、上記圧着面積を適宜調整することで、撥水性・耐水性の要求に対応することができる。 FIG. 4 is a sectional view of a main part of a slide fastener according to a modification of the first embodiment, showing a state in which the first and second element rows are engaged. In the example of FIG. 3, compared to the example of FIG. The crimping area between the surface 13 of the one end 10a of the fastener tape 10 in the width direction and the surface 23 of the one end 20a of the second fastener tape 20 in the width direction is increased. In this way, by appropriately adjusting the crimping area, it is possible to meet the requirements for water repellency and water resistance.
（第２実施形態）
　図５は、第２実施形態に係るスライドファスナーの要部断面図であり、第１及び第２エレメント列を噛合した状態を示す図である。図６は、第２実施形態に係るスライドファスナーの要部断面図であり、第１及び第２エレメント列を分離した状態を示す図である。第２実施形態に係るスライドファスナー１は、第１及び第２ファスナーテープ１０，２０上に第１及び第２止水フィルム７０，８０が設けられる点が第１実施形態とは異なる。第２実施形態のその他の構成は、第１実施形態と同一であるので、図面に第１実施形態と同様の符号を付すことでその説明を省略又は簡略化する。 (Second embodiment)
FIG. 5 is a cross-sectional view of a main part of the slide fastener according to the second embodiment, showing a state in which the first and second element rows are engaged. FIG. 6 is a sectional view of a main part of the slide fastener according to the second embodiment, and is a diagram showing a state in which the first and second element rows are separated. The slide fastener 1 according to the second embodiment differs from the first embodiment in that first and second water- stop films 70 and 80 are provided on the first and second fastener tapes 10 and 20. Since the other configurations of the second embodiment are the same as those of the first embodiment, the explanation thereof will be omitted or simplified by attaching the same reference numerals as those of the first embodiment to the drawings.
　図５及び図６に示すように、第２実施形態のスライドファスナー１は、第１ファスナーテープ１０の表面１３に設けられた第１止水フィルム７０（第１止水層）と、第２ファスナーテープ２０の表面２３に設けられた第２止水フィルム８０（第２止水層）と、を更に備える。したがって、本実施形態のスライドファスナー１は、止水性を有する止水ファスナーである。 As shown in FIGS. 5 and 6, the slide fastener 1 of the second embodiment includes a first water stop film 70 (first water stop layer) provided on the surface 13 of the first fastener tape 10, and a second fastener tape 70 (first water stop layer) provided on the surface 13 of the first fastener tape 10. The tape 20 further includes a second water stop film 80 (second water stop layer) provided on the surface 23 of the tape 20. Therefore, the slide fastener 1 of this embodiment is a water-stop fastener having water-stop properties.
　左右一対の第１及び第２止水フィルム７０はそれぞれ、第１及び第２ファスナーテープ１０，２０と同様の長尺状であって、裏面７１，８１（第１止水主面）と、裏面７１，８１の反対側の表面７３，８３（第２止水主面）と、を有する。第１及び第２止水フィルム７０は、第１及び第２ファスナーテープ１０，２０の表面１３，２３の全面を覆うように形成される。本実施形態では、第１及び第２止水フィルム７０と第１及び第２ファスナーテープ１０，２０との上下寸法及び幅寸法は略同一である。 The left and right pair of first and second water-stopping films 70 have the same elongated shape as the first and second fastener tapes 10 and 20, respectively, and have back surfaces 71 and 81 (first water-stop main surfaces) and a back surface. It has surfaces 73 and 83 (second water-stop main surfaces) opposite to those 71 and 81. The first and second water stop films 70 are formed to cover the entire surfaces 13 and 23 of the first and second fastener tapes 10 and 20. In this embodiment, the vertical dimensions and width dimensions of the first and second water stop films 70 and the first and second fastener tapes 10 and 20 are substantially the same.
　第１及び第２止水フィルム７０は、第１及び第２エレメント列５０，６０が縫着された第１及び第２ファスナーテープ１０，２０の表面１３，２３に、熱硬化性ポリウレタンフィルム等の止水層を、接着や溶着等により接合一体化することにより形成される。ここでスライドファスナー１は、第１及び第２ファスナーテープ１０，２０に共通の止水層（第１及び第２止水フィルム７０，８０）が一体に接合された状態とされる。 The first and second water stop films 70 are made of thermosetting polyurethane film or the like on the surfaces 13 and 23 of the first and second fastener tapes 10 and 20 to which the first and second element rows 50 and 60 are sewn. It is formed by joining and integrating the water stop layer by adhesion, welding, etc. Here, the slide fastener 1 is in a state in which a common water stop layer (first and second water stop films 70, 80) is integrally joined to the first and second fastener tapes 10, 20.
　その後、第１実施形態にて上述した方法と同様の方法にて、スライドファスナー１に撥水剤が付着される。例えば、図示せぬガイドローラーの周面に沿って巻き回してファスナーストリンガ３，５をガイドし、撥水剤を満たした容器内に連続的に通すことにより、撥水剤を浸漬させてもよい。この処理では、ファスナーストリンガ３，５を構成する第１及び第２ファスナーテープ１０，２０、第１及び第２エレメント列５０，６０、芯紐３２、縫糸３３、止水層（第１及び第２止水フィルム７０，８０）の全面に、効率良く撥水剤が付与される。次に、ファスナーストリンガ３，５を容器内から引き上げて、連続的に乾燥室に通すことによって、先ずファスナーストリンガ３，５の全面に付与した撥水剤を乾燥させる。その後、撥水剤の乾燥が終了したファスナーストリンガ３，５を更に連続的に熱処理室に通すことによって、乾燥した撥水剤に熱処理を行う。この熱処理では、第１及び第２ファスナーテープ１０，２０、第１及び第２エレメント列５０，６０、芯紐３２、縫糸３３、止水層（第１及び第２止水フィルム７０，８０）のすべての基材と撥水剤の間で融着、付着処理がなされる。 Thereafter, a water repellent agent is applied to the slide fastener 1 using a method similar to that described above in the first embodiment. For example, the fastener stringers 3 and 5 may be immersed in the water repellent by winding them around the circumferential surface of a guide roller (not shown) to guide them and continuously passing them through a container filled with the water repellent. . In this process, the first and second fastener tapes 10, 20, the first and second element rows 50, 60, the core cord 32, the sewing thread 33, the water stop layer (the first and second The water repellent agent is efficiently applied to the entire surface of the water stop film 70, 80). Next, the water repellent applied to the entire surface of the fastener stringers 3, 5 is first dried by pulling the fastener stringers 3, 5 out of the container and passing them continuously through a drying chamber. Thereafter, the fastener stringers 3 and 5, on which the water repellent has been dried, are further continuously passed through a heat treatment chamber, thereby subjecting the dried water repellent to heat treatment. In this heat treatment, the first and second fastener tapes 10, 20, the first and second element rows 50, 60, the core cord 32, the sewing thread 33, and the water-stop layer (the first and second water-stop films 70, 80) are Fusion and adhesion treatment is performed between all base materials and the water repellent.
　次に、熱処理が終了したスライドファスナー１を取り出して、左右一対のファスナーストリンガ３，５同士を連結している単一の止水層（第１及び第２止水フィルム７０，８０）を、カッター等の切断装置を用いて、第１及び第２エレメント列５０，６０同士が噛合している噛合部に沿って長さ方向に切断し左右に２分させる。このようにして、左右一対の第１及び第２止水フィルム７０，８０が形成される。 Next, the heat-treated slide fastener 1 is taken out, and the single water-stop layer (first and second water-stop films 70, 80) connecting the left and right pair of fastener stringers 3, 5 is cut using a cutter. Using a cutting device such as, etc., the first and second element rows 50 and 60 are cut in the length direction along the meshing portion where they mesh with each other, and are divided into left and right halves. In this way, a pair of left and right first and second water stop films 70 and 80 are formed.
　図６に示すように、第１及び第２エレメント列５０，６０が分離した状態では、第１ファスナーテープ１０及び第１止水フィルム７０の幅方向一端部１０ａ，７０ａと、第２ファスナーテープ２０及び第２止水フィルム８０の幅方向一端部２０ａ，８０ａとは、互いに幅方向に離間している。 As shown in FIG. 6, when the first and second element rows 50, 60 are separated, one widthwise end portion 10a, 70a of the first fastener tape 10 and the first water stop film 70, and the second fastener tape 20 and one end 20a, 80a in the width direction of the second water stop film 80 are spaced apart from each other in the width direction.
　図６に示すように、第１及び第２エレメント列５０，６０が分離している状態で、第１ファスナーテープ１０及び第１止水フィルム７０の幅方向一端部１０ａ，７０ａが第１及び第２エレメント列５０，６０の噛合中心Ｏとなる位置Ｏ１よりも第２ファスナーテープ２０側（幅方向一端側）に延在し、且つ、第２ファスナーテープ２０及び第２止水フィルム８０の幅方向一端部２０ａ，８０ａが噛合中心Ｏとなる位置Ｏ２よりも第１ファスナーテープ１０側（幅方向一端側）に延在する。すなわち、図４に示すように第１及び第２エレメント列５０，６０を噛合させたときに、第１及び第２ファスナーテープ１０，２０が噛合中心Ｏに重なるとともに、第１及び第２止水フィルム７０，８０が噛合中心Ｏに重なるように設計される。このように第１及び第２ファスナーテープ１０，２０と第１及び第２止水フィルム７０，８０と第１及び第２エレメント列５０，６０とを配置することで、後述するように第１及び第２エレメント列５０，６０を噛合させた際に、第１及び第２ファスナーテープ１０，２０並びに第１及び第２止水フィルム７０，８０が山なりに座屈して互いに密着させることができる。 As shown in FIG. 6, when the first and second element rows 50, 60 are separated, one widthwise end portion 10a, 70a of the first fastener tape 10 and the first water stop film 70 is connected to the first and second element rows 50, 60. Extending to the second fastener tape 20 side (one end side in the width direction) from the position O1 which is the meshing center O of the two element rows 50, 60, and in the width direction of the second fastener tape 20 and the second water stop film 80. The one end portions 20a, 80a extend toward the first fastener tape 10 side (one end side in the width direction) from the position O2 where the engagement center O is. That is, when the first and second element rows 50 and 60 are engaged as shown in FIG. 4, the first and second fastener tapes 10 and 20 overlap with the engagement center O, and the first and second water stop tapes The films 70 and 80 are designed to overlap with the meshing center O. By arranging the first and second fastener tapes 10, 20, the first and second water stop films 70, 80, and the first and second element rows 50, 60 in this way, the first and second When the second element rows 50, 60 are engaged, the first and second fastener tapes 10, 20 and the first and second water stop films 70, 80 buckle in a mountainous manner and can be brought into close contact with each other.
　より具体的には、第１及び第２エレメント列５０，６０が分離している状態で、第１ファスナーテープ１０及び第１止水フィルム７０の幅方向一端面１０ｂ，７０ｂが、噛合中心Ｏとなる位置Ｏ１よりも第２ファスナーテープ２０側（幅方向一端側）に配置され、第２ファスナーテープ２０及び第２止水フィルム８０の幅方向一端面２０ｂ，８０ｂが、噛合中心Ｏとなる位置Ｏ２よりも第１ファスナーテープ１０側（幅方向一端側）に配置される。 More specifically, in a state where the first and second element rows 50 and 60 are separated, one end surface 10b and 70b in the width direction of the first fastener tape 10 and the first water stop film 70 is aligned with the meshing center O. The position O2 is located closer to the second fastener tape 20 (on one end in the width direction) than the position O1, and the one end surface 20b, 80b in the width direction of the second fastener tape 20 and the second water stop film 80 is the center of engagement O. It is arranged on the first fastener tape 10 side (one end side in the width direction).
　第１ファスナーテープ１０及び第１止水フィルム７０の幅方向一端面１０ｂ，７０ｂは、幅方向においてエレメント３１の噛合頭部３１ａの少なくとも一部と重なる位置に配置されてもよく、幅方向において噛合頭部３１ａの幅方向一端面３１ｅ（すなわち第１エレメント列５０の幅方向一端面）と同一平面Ｓ１上に配置されてもよく、噛合頭部３１ａよりも第２ファスナーテープ２０側に配置されていてもよい。図６の例では、第１ファスナーテープ１０及び第１止水フィルム７０の幅方向一端面１０ｂ，７０ｂは、幅方向において第１エレメント列５０の幅方向一端面と同一平面Ｓ１上に配置されている。 One end surface 10b, 70b in the width direction of the first fastener tape 10 and the first water stop film 70 may be arranged at a position overlapping with at least a part of the engaging head 31a of the element 31 in the width direction, and It may be arranged on the same plane S1 as one end surface 31e in the width direction of the head 31a (that is, one end surface in the width direction of the first element row 50), and may be arranged closer to the second fastener tape 20 than the engaging head 31a. It's okay. In the example of FIG. 6, one widthwise end surface 10b, 70b of the first fastener tape 10 and the first water stop film 70 is arranged on the same plane S1 as the widthwise one end surface of the first element row 50 in the width direction. There is.
　第２ファスナーテープ２０及び第２止水フィルム８０の幅方向一端面２０ｂ，８０ｂは、幅方向においてエレメント３１の噛合頭部３１ａの少なくとも一部と重なる位置に配置されてもよく、幅方向において噛合頭部３１ａの幅方向一端面３１ｆ（すなわち第２エレメント列６０の幅方向一端面）と同一平面Ｓ２上に配置されてもよく、噛合頭部３１ａよりも第１ファスナーテープ１０側に配置されていてもよい。図６の例では、第２ファスナーテープ２０の幅方向一端面２０ｂは、幅方向において第２エレメント列６０の幅方向一端面と同一平面Ｓ２上に配置されている。 One end surface 20b, 80b in the width direction of the second fastener tape 20 and the second water stop film 80 may be arranged at a position overlapping with at least a part of the engaging head 31a of the element 31 in the width direction, and It may be arranged on the same plane S2 as one widthwise end surface 31f of the head 31a (that is, one widthwise end surface of the second element row 60), and may be arranged closer to the first fastener tape 10 than the engaging head 31a. It's okay. In the example of FIG. 6, one end surface 20b in the width direction of the second fastener tape 20 is disposed on the same plane S2 as one end surface in the width direction of the second element row 60 in the width direction.
　このように、第１ファスナーテープ１０及び第１止水フィルム７０の幅方向一端面１０ｂ，７０ｂと第１エレメント列５０の幅方向一端面とを同一平面Ｓ１上に配置し、第２ファスナーテープ２０及び第２止水フィルム８０の幅方向一端面２０ｂ，８０ｂと第２エレメント列６０の幅方向一端面とを同一平面Ｓ２上に配置することで、第１及び第２エレメント列５０，６０を噛合させた際に、より確実に、第１及び第２ファスナーテープ１０，２０並びに第１及び第２止水フィルム７０，８０が山なりに座屈して互いに密着させることができる。これは、第１及び第２ファスナーテープ１０，２０の幅方向一端部１０ａ，２０ａが第１及び第２エレメント列５０，６０同士の噛み合いを妨げず、第１及び第２ファスナーテープ１０，２０同士の圧着が破綻し難い配置関係であるためである。なお、「同一平面上に配置」とは、必ずしもぴったり同一平面上に配置されている必要はなく、噛合頭部３１ａのテーパを考慮して、ファスナーテープの幅方向一端面が噛合頭部３１ａのテーパの始点からテーパの終点までの範囲と一致する範囲である略同一平面上のものも含まれる。 In this way, one end surface in the width direction 10b, 70b of the first fastener tape 10 and the first water stop film 70 and one end surface in the width direction of the first element row 50 are arranged on the same plane S1, and the second fastener tape 20 By arranging one widthwise end surface 20b, 80b of the second water stop film 80 and one widthwise end surface of the second element row 60 on the same plane S2, the first and second element rows 50, 60 are meshed. When doing so, the first and second fastener tapes 10 and 20 and the first and second water stop films 70 and 80 can be buckled in a mountainous manner and brought into close contact with each other more reliably. This is because the one end portions 10a, 20a in the width direction of the first and second fastener tapes 10, 20 do not prevent the first and second element rows 50, 60 from interlocking with each other, and the first and second fastener tapes 10, 20 do not interfere with each other. This is because the arrangement relationship makes it difficult for the crimping to fail. Note that "arranged on the same plane" does not necessarily mean that they are arranged exactly on the same plane, but in consideration of the taper of the interlocking head 31a, one end surface in the width direction of the fastener tape is aligned with the interlocking head 31a. It also includes a range that is substantially on the same plane as the range from the start point of the taper to the end point of the taper.
　図６に示すような第１及び第２エレメント列５０，６０が分離した状態から、スライダー４０を上方に移動することで、図５に示すように左右一対の第１及び第２エレメント列５０，６０が噛合する。この際、第１ファスナーテープ１０及び第１止水フィルム７０の幅方向一端部１０ａ，７０ａが第１及び第２エレメント列５０，６０の噛合中心Ｏとなる位置Ｏ１よりも第２ファスナーテープ２０側（幅方向一端側）に延在し、且つ、第２ファスナーテープ２０及び第２止水フィルム８０の幅方向一端部２０ａ，８０ａが噛合中心Ｏとなる位置Ｏ２よりも第１ファスナーテープ１０側（幅方向一端側）に延在しているので、幅方向一端部１０ａ，７０ａと幅方向一端部２０ａ，８０ａとは、互いに幅方向に押し合って変形し、表側に凸である山なりに座屈して互いに密着する。なお、この際に、図２に示すように第１及び第２ファスナーテープ１０，２０に縫い付けられた縫糸３３であって、かつ第１及び第２ファスナーテープ１０，２０の幅方向一端部１０ａ，２０ａ側の縫糸３３が、第１及び第２ファスナーテープ１０，２０の座屈に伴って若干伸びて浮き上がることもある。 By moving the slider 40 upward from the state where the first and second element rows 50 and 60 are separated as shown in FIG. 60 meshes. At this time, one end 10a, 70a in the width direction of the first fastener tape 10 and the first water stop film 70 is closer to the second fastener tape 20 than the position O1 where the meshing center O of the first and second element rows 50, 60 is. (one end side in the width direction), and the first fastener tape 10 side ( Since the widthwise end portions 10a and 70a and the widthwise end portions 20a and 80a are pressed against each other in the widthwise direction and deformed, they sit in a convex mountain shape on the front side. Bend over and cling to each other. In addition, at this time, as shown in FIG. , 20a side may stretch a little and float up as the first and second fastener tapes 10 and 20 buckle.
　このように、第１及び第２エレメント列５０，６０を互いに噛み合わせた際に、第１及び第２ファスナーテープ１０，２０並びに第１及び第２止水フィルム７０，８０が互いに密着するので、従来の裏使いスライドファスナーのように、第１及び第２ファスナーテープ１０，２０並びに第１及び第２止水フィルム７０，８０の間に隙間（いわゆる中仕切部）が形成されることはない。したがって、使用者がスライドファスナー１を表側から見た時に、第１及び第２エレメント列５０，６０が視認されず、外観に優れる。このようなスライドファスナー１は、特に、カーシート、鞄、家具等の美観が重視される物品に好適である。 In this way, when the first and second element rows 50 and 60 are engaged with each other, the first and second fastener tapes 10 and 20 and the first and second water stop films 70 and 80 are in close contact with each other, so that Unlike conventional reverse slide fasteners, no gap (so-called inner partition) is formed between the first and second fastener tapes 10, 20 and the first and second water- stop films 70, 80. Therefore, when the user views the slide fastener 1 from the front side, the first and second element rows 50 and 60 are not visible, resulting in an excellent appearance. Such a slide fastener 1 is particularly suitable for articles where aesthetics are important, such as car seats, bags, and furniture.
　また、第１及び第２ファスナーテープ１０，２０並びに第１及び第２止水フィルム７０，８０は山なりに座屈して互いに密着するので、第１及び第２ファスナーテープ１０，２０に互いに離れる方向の力（いわゆる横引き）が作用した場合であっても、エレメント３１，３１同士の噛み合いギャップが打ち消される範囲において、座屈度合いが多少弱まるだけで互いの密着状態は維持されるので、スライドファスナー１の良好な外観が保たれる。 In addition, since the first and second fastener tapes 10, 20 and the first and second water stop films 70, 80 buckle in a mountain shape and come into close contact with each other, the first and second fastener tapes 10, 20 are separated from each other. Even if a force (so-called lateral pull) is applied, within the range where the meshing gap between the elements 31 and 31 is canceled out, the degree of buckling will be slightly weakened and the state of close contact with each other will be maintained, so the slide fastener The good appearance of No. 1 is maintained.
　第１及び第２エレメント列５０，６０を互いに噛み合わせた際に第１及び第２ファスナーテープ並びに第１及び第２止水フィルム７０，８０が山なりに座屈して互いに密着するので、第１及び第２ファスナーテープ１０，２０並びに第１及び第２止水フィルム７０，８０の間に隙間（中仕切部）が形成されることはなく、従来技術のように中仕切部から液体が進入することが抑制される。 When the first and second element rows 50 and 60 are engaged with each other, the first and second fastener tapes and the first and second water stop films 70 and 80 buckle in a mountain shape and come into close contact with each other. A gap (inner partition) is not formed between the second fastener tapes 10, 20 and the first and second water stop films 70, 80, and liquid enters from the inner partition as in the prior art. things are suppressed.
　また、図５に示すように、第１及び第２エレメント列５０，６０を互いに噛み合わせた際に、第１及び第２ファスナーテープ１０，２０の幅方向一端面１０ｂ及び幅方向一端面２０ｂ並びに第１及び第２止水フィルム７０，８０の幅方向一端面７０ｂ及び幅方向一端面８０ｂは、エレメント３１側（裏側）を向く。第１及び第２止水フィルム７０，８０の幅方向一端面７０ｂ及び幅方向一端面８０ｂは、第１及び第２エレメント列５０，６０に当接することもある。また、第１止水フィルム７０の幅方向一端部７０ａの表面７３と、第２止水フィルム８０の幅方向一端部８０ａの表面８３とが、噛合中心Ｏ上で互いに密着する。したがって、液体浸入抑制効果を向上できる。 Further, as shown in FIG. 5, when the first and second element rows 50 and 60 are engaged with each other, one end surface 10b in the width direction and one end surface 20b in the width direction of the first and second fastener tapes 10 and 20, One end surface 70b in the width direction and one end surface 80b in the width direction of the first and second water stop films 70, 80 face the element 31 side (back side). One end surface 70b in the width direction and one end surface 80b in the width direction of the first and second water stop films 70 and 80 may come into contact with the first and second element rows 50 and 60. Further, the surface 73 of the first end 70a in the width direction of the first water stop film 70 and the surface 83 of the end 80a in the width direction of the second water stop film 80 are in close contact with each other on the meshing center O. Therefore, the effect of suppressing liquid intrusion can be improved.
　図７は、第２実施形態の変形例に係るスライドファスナーの要部断面図であり、第１及び第２エレメント列を噛合した状態を示す図である。図７の例においては、図５の例に比べて、第１ファスナーテープ１０及び第１止水フィルム７０の幅方向一端部１０ａ，７０ａ並びに第２ファスナーテープ２０及び第２止水フィルム８０の幅方向一端部２０ａ，８０ａの座屈度合いが強められており、第１止水フィルム７０の幅方向一端部７０ａの表面７３と、第２止水フィルム８０の幅方向一端部８０ａの表面８３と、の圧着面積が増加している。このように、上記圧着面積を適宜調整することで、止水性・耐水性の要求に対応することができる。 FIG. 7 is a cross-sectional view of a main part of a slide fastener according to a modification of the second embodiment, showing a state in which the first and second element rows are engaged. In the example of FIG. 7, compared to the example of FIG. The degree of buckling of the one end portions 20a and 80a in the direction is increased, and the surface 73 of the one end portion 70a of the first water stop film 70 in the width direction, and the surface 83 of the one end portion 80a of the second water stop film 80 in the width direction, Crimp area is increasing. In this way, by appropriately adjusting the crimped area, it is possible to meet the requirements for water-stopping properties and water resistance.
　なお、本発明は上記実施形態に例示したものに限定されるものではなく、本発明の要旨を逸脱しない範囲において適宜変更可能である。 It should be noted that the present invention is not limited to what is exemplified in the above embodiments, and can be modified as appropriate without departing from the gist of the present invention.
　以上のとおり、本明細書には次の事項が開示されている。 As mentioned above, the following matters are disclosed in this specification.
　［１］　長尺状であって、それぞれ第１主面（１１，２１）と前記第１主面（１１，２１）の反対側の第２主面（１３，２３）とを有する、一対の第１及び第２ファスナーテープ（１０，２０）と、
　前記第１ファスナーテープ（１０）の幅方向一端部（１０ａ）の前記第１主面（１１）に設けられた、第１エレメント列（５０）と、
　前記第２ファスナーテープ（２０）の幅方向一端部（２０ａ）の前記第１主面（２１）に設けられた、第２エレメント列（６０）と、
を備えるスライドファスナー（１）であって、
　前記第１及び第２エレメント列（５０，６０）を互いに噛み合わせた際に、前記第１ファスナーテープ（１０）の幅方向一端部（１０ａ）と、前記第２ファスナーテープ（２０）の幅方向一端部（２０ａ）と、がそれぞれ山なりに座屈して互いに密着する、
スライドファスナー（１）。 [1] A pair of elongated surfaces each having a first main surface (11, 21) and a second main surface (13, 23) opposite to the first main surface (11, 21). first and second fastener tapes (10, 20);
a first element row (50) provided on the first main surface (11) of the first end (10a) in the width direction of the first fastener tape (10);
a second element row (60) provided on the first main surface (21) of one end (20a) in the width direction of the second fastener tape (20);
A slide fastener (1) comprising:
When the first and second element rows (50, 60) are engaged with each other, one end (10a) in the width direction of the first fastener tape (10) and the width direction of the second fastener tape (20) The one end portion (20a) is buckled in a mountain shape and comes into close contact with each other,
Slide fastener (1).
　この構成によれば、第１及び第２エレメント列（５０，６０）を互いに噛み合わせた際に、第１及び第２ファスナーテープ（１０，２０）が互いに密着するので、従来の裏使いスライドファスナーのように、第１及び第２ファスナーテープ（１０，２０）の間に隙間（いわゆる中仕切部）が形成されることはない。したがって、使用者がスライドファスナー（１）を表側から見た時に、第１及び第２エレメント列（５０，６０）が視認されず、外観に優れる。このようなスライドファスナー（１）は、特に、カーシート、鞄、家具等の美観が重視される物品に好適である。また、第１及び第２ファスナーテープ（１０，２０）は山なりに座屈して互いに密着するので、第１及び第２ファスナーテープ（１０，２０）に互いに離れる方向の力（いわゆる横引き）が作用した場合であっても、エレメント（３１，３１）同士の噛み合いギャップが打ち消される範囲において、座屈度合いが多少弱まるだけで互いの密着状態は維持されるので、スライドファスナー（１）の良好な外観が保たれる。 According to this configuration, when the first and second element rows (50, 60) are engaged with each other, the first and second fastener tapes (10, 20) are in close contact with each other, so that the conventional reverse slide fastener Thus, no gap (so-called partition) is formed between the first and second fastener tapes (10, 20). Therefore, when the user views the slide fastener (1) from the front side, the first and second element rows (50, 60) are not visible, resulting in an excellent appearance. Such a slide fastener (1) is particularly suitable for articles where aesthetics are important, such as car seats, bags, and furniture. In addition, since the first and second fastener tapes (10, 20) buckle in a mountain shape and come into close contact with each other, forces in the direction of separating the first and second fastener tapes (10, 20) from each other (so-called lateral pulling) are applied to the first and second fastener tapes (10, 20). Even if the elements (31, 31) engage with each other, their close contact with each other is maintained within the range where the meshing gap between the elements (31, 31) is canceled out, and the degree of buckling is only slightly weakened. Appearance is maintained.
　［２］　前記第１及び第２エレメント列（５０，６０）を互いに噛み合わせた際に、前記第１ファスナーテープ（１０）の幅方向一端部（１０ａ）の前記第２主面（１３）と、前記第２ファスナーテープ（２０）の幅方向一端部（２０ａ）の前記第２主面（２３）と、が互いに密着する、
［１］に記載のスライドファスナー（１）。 [2] When the first and second element rows (50, 60) are engaged with each other, the second main surface (13) of the one widthwise end (10a) of the first fastener tape (10) , the second main surface (23) of the one end (20a) in the width direction of the second fastener tape (20) is in close contact with each other;
Slide fastener (1) according to [1].
　この構成によれば、第１及び第２ファスナーテープ（１０，２０）の幅方向一端部（１０ａ，２０ａ）の第２主面（１３，２３）同士が密着するので、第１主面（１１，２１）同士を密着させた場合に比べて、スライドファスナー（１）の厚さを抑えるとともに、スライダー（４０）の摺動抵抗を軽減できる。 According to this configuration, the second main surfaces (13, 23) of the widthwise one ends (10a, 20a) of the first and second fastener tapes (10, 20) are in close contact with each other, so the first main surface (11 , 21), the thickness of the slide fastener (1) can be suppressed and the sliding resistance of the slider (40) can be reduced compared to the case where the slide fasteners (1) are brought into close contact with each other.
　［３］　前記第１及び第２エレメント列（５０，６０）を互いに噛み合わせた際に、前記第１ファスナーテープの幅方向一端部（１０ａ）の前記第１主面（１１）と前記第１エレメント列（５０）との間には第１空間（Ｔ１）が画成され、
　前記第２ファスナーテープ（２０）の幅方向一端部（２０ａ）の前記第１主面（２１）と前記第２エレメント列（６０）との間には第２空間（Ｔ２）が画成される、
［１］又は［２］に記載のスライドファスナー（１）。 [3] When the first and second element rows (50, 60) are engaged with each other, the first main surface (11) of the one widthwise end (10a) of the first fastener tape and the first A first space (T1) is defined between the element row (50),
A second space (T2) is defined between the first main surface (21) of the one widthwise end (20a) of the second fastener tape (20) and the second element row (60). ,
The slide fastener (1) according to [1] or [2].
　この構成によれば、第１及び第２空間（Ｔ１，Ｔ２）が設けられることで，スライダー（４０）で第１及び第２エレメント列（５０，６０）を組み合わせた際、第１及び第２ファスナーテープ（１０，２０）を容易に座屈させることができる。また、第１及び第２空間（Ｔ１，Ｔ２）が大きいほど、第１及び第２ファスナーテープ（１０，２０）の幅方向一端面（１０ｂ）及び幅方向一端面（２０ｂ）の第１主面（１１，２１）同士の圧着面積が大きくなり、第１及び第２ファスナーテープ（１０，２０）の間の隙間（中仕切部）の発生が抑制され、外観の向上や止水性・耐水性の向上に寄与できる。さらに、第１及び第２ファスナーテープ（１０，２０）同士の圧着の破綻がしにくくなり、形状が維持されやすい。 According to this configuration, by providing the first and second spaces (T1, T2), when the first and second element rows (50, 60) are combined with the slider (40), the first and second spaces (T1, T2) are provided. The fastener tape (10, 20) can be easily buckled. Moreover, the larger the first and second spaces (T1, T2), the first main surface of the one widthwise end surface (10b) and the widthwise one end surface (20b) of the first and second fastener tapes (10, 20). The crimping area between (11, 21) becomes larger, and the generation of gaps (partitions) between the first and second fastener tapes (10, 20) is suppressed, improving the appearance and improving water-stopping and water-resistance properties. Can contribute to improvement. Furthermore, the crimping between the first and second fastener tapes (10, 20) is less likely to break down, and the shape is easily maintained.
　［４］　前記第１及び第２ファスナーテープ（２０）は、織物又は編物である、
