Description of the Related Art Conventionally, a break-and-fit insert including a box bar, a box, and a butterfly bar connected to the lower ends of the dental dentitions arranged on one side edge of the left and right fastener stringers, and the break-and-insert insert There is provided a slide fastener comprising If washing is performed with the butterfly pin still inserted into the slide fastener box with the separation / insertion tool, the compression force is applied to the separation / insertion tool during washing, resulting in damage to the box. Etc. had caused such problems.
　この、箱体の破損を防止することを目的として、可撓性を備えた弾性体で箱体を構成し、箱体における蝶棒の嵌挿部を貫通形とし、蝶棒側のファスナーテープが挿通するテープ溝の隙間を、蝶棒の厚さに対応して従来の隙間よりも幅広に形成したスライドファスナーの開離嵌挿具が、特許文献１に開示されている（中華民国専利公報　広告編　第３４０３１５号）。 For the purpose of preventing breakage of the box body, the box body is constituted by an elastic body having flexibility, the insertion part of the butterfly stick in the box body is a penetration type, A slide fastener opening / closing insertion tool in which the gap of the tape groove to be inserted is formed wider than the conventional gap corresponding to the thickness of the butterfly stick is disclosed in Patent Document 1 (Republic of China Patent Publication) Ed.

　ここで、スライダーを箱体に接触する最下位まで下げることを必要とせず、スライダーの位置に依らずスライドファスナーを瞬時に開く操作を行うことを可能としたクイックオープン式スライドファスナーと、そのクイックオープン式スライドファスナーに好適な開離嵌挿具について考察する。 Here, it is not necessary to lower the slider to the lowest position in contact with the box, and the quick open type slide fastener that can open the slide fastener instantly regardless of the position of the slider, and its quick open Discusses suitable opening and closing inserts for the type slide fastener.
　クイックオープン式スライドファスナーでは、利用者が左右のファスナーストリンガーを把持し、それを左右方向に開く操作を行う。すると、スライダーの務歯挿通路内に挿通している一方のファスナーストリンガーを、スライダーのテープ溝を介してスライダーから外すことができる。その後は、スライダーの外で噛合状態にある左右の務歯列を連鎖的に下端まで外してゆくことができる。 In quick-open slide fasteners, the user holds the left and right fastener stringers and opens them in the left-right direction. Then, one fastener stringer inserted in the engagement tooth insertion passage of the slider can be removed from the slider through the tape groove of the slider. Thereafter, the left and right dentitions that are meshed outside the slider can be chained off to the lower end.
　しかし、左右のファスナーストリンガーの下端に配されている開離嵌挿具の箱体には、蝶棒が上方から嵌入された状態となっている。このため、利用者は、左右の務歯列の噛合を連鎖的に下端まで外した後に、蝶棒の側方のファスナーテープを持って上方へ持ち上げて、蝶棒を箱体から抜き取る操作を行う必要があった。 However, a butterfly stick is inserted from above into the box of the open / close insert placed at the lower ends of the left and right fastener stringers. For this reason, the user performs the operation of removing the butterfly bar from the box by lifting the upper side with the zipper tape on the side of the butterfly bar after removing the engagement of the left and right dentitions to the lower end. There was a need.
　特許文献１に記載されている開離嵌挿具をクイックオープン式スライドファスナーに適用した場合には、左右の務歯列を連鎖的に下端まで外した後においても、左右のファスナーストリンガーを左右方向に開く操作を続けることで、蝶棒を箱体から側方に外すことが可能である。このとき、左右のファスナーストリンガーを左右方向に開く操作を続けることにより、蝶棒が箱体を弾性変形させて、テープ溝が拡幅することになる。そして、その拡幅したテープ溝から蝶棒を側方に外すことが可能である。 When the open / close insert described in Patent Document 1 is applied to a quick-open slide fastener, the left and right fastener stringers can be moved in the left-right direction even after the left and right dentitions are chained to the lower end. It is possible to remove the butterfly stick from the box sideways by continuing the opening operation. At this time, by continuing the operation of opening the left and right fastener stringers in the left-right direction, the butterfly stick elastically deforms the box and the tape groove is widened. And it is possible to remove a butterfly stick laterally from the widened tape groove.
　しかし、蝶棒がテープ溝から側方に外れるようになるまでテープ溝を拡幅させるためには、箱体を弾性変形させるための強い引張力を左右方向に加え続ける必要がある。これは、クイックオープン式スライドファスナーを即時に開裂させる際の操作性を悪化させる要因となる。 However, in order to widen the tape groove until the butterfly stick comes to the side from the tape groove, it is necessary to continue to apply a strong tensile force to elastically deform the box in the left-right direction. This becomes a factor that deteriorates the operability when the quick open slide fastener is immediately cleaved.
　本発明は、こうした従来技術を改善するために創出されたもので、噛合状態にある左右のファスナーストリンガーを左右方向に開く操作を行った場合に、最後まで軽い力で箱体から蝶棒を外すことが可能な開離嵌挿具付スライドファスナーを提供することを目的としている。 The present invention was created to improve such a conventional technique. When the left and right fastener stringers in the meshing state are opened in the left-right direction, the butterfly stick is removed from the box with a light force until the end. An object of the present invention is to provide a slide fastener with an opening / closing insertion tool that can be used.
　上記課題を解決するために本発明に係る開離嵌挿具付スライドファスナーは、スライドファスナーにおける左右一対のファスナーストリンガーのうち、第１ファスナーストリンガーにおけるファスナーテープの一側縁に配された第１務歯列の下端に連設された蝶棒と、第２ファスナーストリンガーの一側縁に配される第２務歯列の下端に連設された箱棒と、前記箱棒の下端に固定され、前記蝶棒を挿抜可能に遊嵌するための四側部により形成される嵌挿部を備える箱体とを有する開離嵌挿具付スライドファスナーにおいて、前記第１及び第２ファスナーストリンガーを構成するファスナーテープの一方の面を表面とし、当該表面とは反対側の面を裏面とした際に、前記四側部のうちの前記表面側の側部に形成した表壁面、及び、前記裏面側の側部に形成した裏抜止突片と、前記四側部のうちの前記箱棒側の側部に形成した箱棒側壁面、及び、前記箱棒側壁面から離間する離間側の側部に形成した離間側抜止突片とを備え、前記表壁面又は前記箱棒側壁面と対向する面側に、前記蝶棒を傾斜させた姿勢で抜くための開口を形成してなることを特徴とする。 In order to solve the above-mentioned problem, the slide fastener with a break-fitting insert according to the present invention is the first task arranged on one side edge of the fastener tape in the first fastener stringer among the pair of left and right fastener stringers in the slide fastener.

　また、他の発明によれば、離間側抜止突片を表壁面から突出させたので、表壁面及び箱棒側壁面の対面において広い開口を形成することができる。この開口から蝶棒を傾けながら外すことができるので、軽い力で素早く蝶棒を箱体から外すことができる。 Further, according to another invention, since the separation-side retaining protrusion protrudes from the front wall surface, a wide opening can be formed on the facing surface wall and the box bar side wall surface. Since the butterfly stick can be removed from the opening while being tilted, the butterfly stick can be quickly removed from the box with a light force.
　また、他の発明によれば、裏抜止突片を、箱棒側壁面から突出させたので、表壁面及び箱棒側壁面の対面において広い開口を形成することができる。この開口から蝶棒を傾けながら外すことができるので、軽い力で素早く蝶棒を箱体から外すことができる。 Further, according to another invention, since the back-preventing protrusion is protruded from the box bar side wall surface, a wide opening can be formed on the front wall surface and the box bar side wall surface. Since the butterfly stick can be removed from the opening while being tilted, the butterfly stick can be quickly removed from the box with a light force.
　また、他の発明によれば、嵌挿部の最奥端に底壁を備え、裏抜止突片を底壁から突出させたので、表壁面及び箱棒側壁面の対面において広い開口を形成することができる。この開口から蝶棒を傾けながら外すことができるので、軽い力で素早く蝶棒を箱体から外すことができる。 Further, according to another invention, the bottom wall is provided at the innermost end of the insertion portion, and the back-preventing protrusion is protruded from the bottom wall, so that a wide opening is formed on the front wall surface and the box bar side wall surface. be able to. Since the butterfly stick can be removed from the opening while being tilted, the butterfly stick can be quickly removed from the box with a light force.
　また、他の発明によれば、嵌挿部の最奥端に底壁を備え、裏抜止突片を箱棒側壁面及び底壁の双方から突出させたので、裏抜止突片の剛性を向上させることができる。これにより、箱体から簡単に蝶棒が外れてしまう不具合を予防しつつ、表壁面及び箱棒側壁面の対面において形成される開口から蝶棒を傾けながら容易に外すことができる。 In addition, according to another invention, the bottom wall is provided at the innermost end of the insertion portion, and the back removal preventing protrusion is protruded from both the box bar side wall surface and the bottom wall, so that the rigidity of the back removal preventing protrusion is improved.

　クイックオープン式スライドファスナー１０は、スライドファスナーを構成する左右の第１ファスナーストリンガー１６及び第２ファスナーストリンガー１７と、第１ファスナーストリンガー１６及び第２ファスナーストリンガー１７の対向する側縁部に沿って配された左右の芯部１４と、それぞれの芯部１４を挟持するように所定の間隔をおいて多数の務歯を列設した第１務歯列１２及び第２務歯列１３と、第１務歯列１２及び第２務歯列１３を挿通して上開きを可能にするスライダー５０とを備えている。なお、第１務歯列１２及び第２務歯列１３を構成する各務歯の素材として、ポリアセタール等の樹脂成形品を用いることができる。 The quick-open slide fastener 10 is arranged along the left and right first fastener stringers 16 and second fastener stringers 17 constituting the slide fastener, and opposite side edges of the first fastener stringers 16 and second fastener stringers 17. The left and right core portions 14, a first service tooth row 12 and a second service tooth row 13 in which a number of service teeth are arranged at predetermined intervals so as to sandwich each core portion 14, and the first service And a slider 50 that allows the upper row of the teeth 12 and the second tooth 13 to be opened. A resin molded product such as polyacetal can be used as a material for each service tooth constituting the first service tooth row 12 and the second service tooth row 13.
　スライダー５０の上翼片５２及び下翼片５３の両側縁部には、スライダー５０の移動に伴い第１務歯列１２及び第２務歯列１３同士を噛み合わせてゆくために、双方の務歯同士を引き合わせるフランジ５０Ｆを延設してある。この上翼片５２及び下翼片５３のフランジ５０Ｆ同士が対向する細長い隙間部分は、第１ファスナーストリンガー１６及び第２ファスナーストリンガー１７のファスナーテープを挿通させるためのテープ溝となっている。 The both side edges of the upper wing piece 52 and the lower wing piece 53 of the slider 50 are engaged with each other in order to engage the first dentition row 12 and the second dentition row 13 with the movement of the slider 50. A flange 50F for pulling teeth is extended. The elongated gap portion where the flanges 50F of the upper wing piece 52 and the lower wing piece 53 face each other is a tape groove for inserting the fastener tapes of the first fastener stringer 16 and the second fastener stringer 17.
　スライダー５０の内部には、第１務歯列１２及び第２務歯列１３をスライダー５０の前後方向に貫通させるための務歯案内通路が、左右のフランジ５０Ｆで囲まれる形でＹ字形に形成されている。また、務歯案内通路の肩口側の中央部には、上翼片５２と下翼片５３とを連結する連結柱５０Ｄを配してある。 In the slider 50, a tooth guide passage for penetrating the first service tooth row 12 and the second service tooth row 13 in the front-rear direction of the slider 50 is formed in a Y shape so as to be surrounded by the left and right flanges 50F. Has been. Further, a connecting column 50D for connecting the upper wing piece 52 and the lower wing piece 53 is arranged in the central portion on the shoulder opening side of the service tooth guide passage.
　務歯案内通路の両端には、スライダー５０の前端側の連結柱５０Ｄの両側に設けられた左右の肩口と、後端側に設けられた後口とを有している。スライダー５０の肩口は、分離した左右の務歯を務歯案内通路へ導入又は排出し、後口は、噛合した左右の務歯を務歯案内通路へ導入又は排出する。 At both ends of the service tooth guide passage, there are left and right shoulder openings provided on both sides of the connecting column 50D on the front end side of the slider 50, and a rear opening provided on the rear end side. The shoulder of the slider 50 introduces or ejects the separated left and right engaging teeth into the engaging tooth guide passage, and the rear opening introduces or discharges the engaged left and right engaging teeth into the engaging tooth guide passage.
　スライダー５０を、第１務歯列１２及び第２務歯列１３に沿ってスライドファスナーの上方に向かって上げる操作を行うと、スライダー５０の後口からは、分離状態にあった左右の第１務歯列１２及び第２務歯列１３が噛合状態となって出てくる。逆に、スライダー５０を下げる操作を行ってゆくと、スライダー５０の後口から噛合状態の第１務歯列１２及び第２務歯列１３が導入され、左右の肩口からは第１務歯列１２及び第２務歯列１３が分離状態となって出てくる。 When the slider 50 is moved upward along the first service tooth row 12 and the second service tooth row 13 toward the upper side of the slide fastener, the left and right first left and right sides in the separated state are seen from the rear opening of the slider 50. The service tooth row 12 and the second service tooth row 13 come out in mesh. On the contrary, when the operation of lowering the slider 50 is performed, the meshing first dentition 12 and the second dentition 13 are introduced from the rear opening of the slider 50, and the first dentition from the left and right shoulders. 12 and the second service tooth row 13 come out in a separated state.
　第１ファスナーストリンガー１６における第１務歯列１２の上端と連接する上方には、第１務歯列１２の務歯の頭部とは異なる形状の通過式上止め１８ａが、芯部１４を挟み込む形で固着してある。第２ファスナーストリンガー１７における第２務歯列１３は、通過式上止め１８ａの上端よりもスライダー５０一個ぶん上まで第２務歯列１３を連接して配置し、その第２務歯列１３の上端と連接する上方に、芯部１４を挟み込む形で上止め１８を固着してある。 On the upper side of the first fastener stringer 16, which is connected to the upper end of the first service tooth row 12, a passing type upper stopper 18 a having a shape different from the head of the service tooth of the first service tooth row 12 sandwiches the core portion 14. It is fixed in shape. The second service tooth row 13 in the second fastener stringer 17 is arranged so that the second service tooth row 13 is connected to one slider 50 above the upper end of the passing type upper stopper 18a. An upper stopper 18 is fixed to the upper part connected to the upper end so as to sandwich the core part 14.
　第１ファスナーストリンガー１６における第１務歯列１２の下方には蝶棒３０を連設してあり、第２ファスナーストリンガー１７における第２務歯列１３の下方には、箱棒４０を連接してある。 A butterfly pin 30 is connected to the first fastener stringer 16 below the first service tooth row 12, and a box bar 40 is connected to the second fastener stringer 17 below the second service tooth row 13. is there.
　箱棒４０の下端部には、蝶棒３０の下端部を嵌挿することで、左右の第１ファスナーストリンガー１６と第２ファスナーストリンガー１７とを結合させる箱体４０Ｂを備えている。この箱体４０Ｂには、蝶棒３０の下端部を嵌挿するための嵌挿部４０Ｚ（後段にて説明する図２～図４参照。）を形成してある。 The lower end of the box bar 40 is provided with a box 40B for connecting the left and right first fastener stringers 16 and the second fastener stringers 17 by fitting the lower end parts of the butterfly sticks 30 into each other. The box 40B is formed with an insertion portion 40Z (see FIGS. 2 to 4 described later) for inserting the lower end portion of the butterfly stick 30.
　図１に示すように、第１ファスナーストリンガー１６下端の表裏には、樹脂製フィルムなどによる補強フィルム２４を貼着してある。そして、この補強フィルム２４及び芯部１４を共に挟み込む形で蝶棒３０を固着してある。また、同様に、第２ファスナーストリンガー１７下端の表裏にも、補強フィルム２４を貼着してある。この補強フィルム２４及び芯部１４を共に挟み込む形で箱棒４０を固着してある。 As shown in FIG. 1, a reinforcing film 24 made of a resin film or the like is attached to the front and back of the lower end of the first fastener stringer 16. And the butterfly stick 30 is fixed in such a manner as to sandwich the reinforcing film 24 and the core part 14 together. Similarly, a reinforcing film 24 is also attached to the front and back of the lower end of the second fastener stringer 17. A box bar 40 is fixed in such a manner as to sandwich the reinforcing film 24 and the core part 14 together.
　箱棒４０における蝶棒３０と相対する対向側面の第２務歯列１３側には、平面視台形平板状の第２係止部４４が突出している。第２係止部４４は、後述する蝶棒３０の第１係止部３４と係合する部分である。 A second locking portion 44 having a trapezoidal flat plate shape in a plan view protrudes on the side of the box rod 40 facing the butterfly pin 30 on the second engagement tooth row 13 side. The 2nd latching | locking part 44 is a part engaged with the 1st latching | locking part 34 of the butterfly stick 30 mentioned later.
　蝶棒３０における箱棒４０と相対する対向側面には、係止面を下方に向けた第１係止部３４が、両側壁により補強された形で突出している。この第１係止部３４は、最下位に移動させたスライダー５０に蝶棒３０を挿入した際に、箱棒４０の第２係止部４４と係合させることで、蝶棒３０を箱棒４０に対してスライドファスナーの長手方向に位置決めするための部分である。第１係止部３４の下側には、両側壁で囲まれた凹陥部３３が形成されている。この凹陥部３３には、箱棒４０の第２係止部４４が進入する。 On the opposite side of the butterfly stick 30 facing the box bar 40, a first locking portion 34 with the locking surface facing downward protrudes in a form reinforced by both side walls. The first locking portion 34 is engaged with the second locking portion 44 of the box rod 40 when the butterfly pin 30 is inserted into the slider 50 moved to the lowest position, so that the butterfly pin 30 is engaged with the box rod. 40 is a portion for positioning in the longitudinal direction of the slide fastener with respect to 40. A recessed portion 33 surrounded by both side walls is formed below the first locking portion 34. The second locking portion 44 of the box bar 40 enters the recessed portion 33.
　次に、スライダー５０を下げる操作を行うことを必要とせず、噛合状態にある左右のファスナーストリンガーを即時に開裂させる手順について、以下に説明する。 Next, the procedure for immediately cleaving the right and left fastener stringers in an engaged state without requiring the operation of lowering the slider 50 will be described below.
　先ず、第１ファスナーストリンガー１６の上部に固着されている通過式上止め１８ａに向けてスライダー５０を軽く上げる操作を行い続けると、通過式上止め１８ａがスライダー５０の移動を妨げる。したがって、スライダー５０が通過式上止め１８ａと当接した位置で、スライダー５０を一旦係止させることができる。この、通過式上止め１８ａにスライダー５０が当接した状態が、クイックオープン式スライドファスナー１０を閉じた状態であり、衣服の左前身頃と右前身頃とが閉じた状態となる。 First, if the operation of slightly raising the slider 50 toward the passing type upper stopper 18a fixed to the upper portion of the first fastener stringer 16 is continued, the passing type upper stopper 18a prevents the slider 50 from moving. Therefore, the slider 50 can be temporarily locked at the position where the slider 50 is in contact with the passing type upper stopper 18a. The state in which the slider 50 is in contact with the passing type upper stopper 18a is a state in which the quick-open type slide fastener 10 is closed, and the left front body and the right front body of the clothing are in a closed state.
　通過式上止め１８ａにおける第２務歯列１３側に形成されている可撓部１８ｂは、芯部１４側に向けて撓みやすくなるように、芯部１４側との間に空間部を形成して可撓性を与えている部分である。このように、通過式上止め１８ａの頂部に可撓部１８ｂを形成することにより、通過式上止め１８ａにスライダー５０が当接した位置から、更に利用者がスライダー５０を上に移動させる力を加えた場合に、スライダー５０の務歯挿通路内部において、通過式上止め１８ａの頂部の可撓部１８ｂに対向する位置の第２務歯列１３の務歯の頭部を、可撓部１８ｂに食い込ませることができる。 The flexible portion 18b formed on the second engagement tooth row 13 side of the passing type upper stopper 18a forms a space between the flexible portion 18b and the core portion 14 side so as to be easily bent toward the core portion 14 side. It is a part which gives flexibility. In this way, by forming the flexible portion 18b on the top of the pass-type top stopper 18a, the user can further move the slider 50 upward from the position where the slider 50 abuts the pass-type top stopper 18a. When added, the head of the dentition of the second dentition 13 at the position facing the flexible portion 18b at the top of the passing type upper stopper 18a inside the dentition insertion passage of the slider 50 is changed to the flexible portion 18b. Can bite into.
　すると、スライダー５０が通過式上止め１８ａを通過することが可能となり、スライダー５０を更に上に移動させることができる。そして、剛体で形成されている上止め１８に、スライダー５０の肩口が当接する位置（図１に示す二点鎖線の位置）まで移動させることができるようになる。図１に示すように、第１ファスナーストリンガー１６の通過式上止め１８ａよりも上方には、第１務歯列１２が固着されていない。したがって、スライダー５０の肩口が上止め１８と当接する位置にある状態では、スライダー５０の務歯挿通路内に存在するのは、第１ファスナーストリンガー１６側の芯部１４と、第２ファスナーストリンガー１７側の第２務歯列１３とである。第１ファスナーストリンガー１６側には第１務歯列１２が存在していないので、この通過式上止め１８ａより上位に固着されている第２務歯列１３は、噛合していない状態となっている。 Then, it becomes possible for the slider 50 to pass the passing type top stopper 18a, and the slider 50 can be moved further upward. Then, the upper stopper 18 formed of a rigid body can be moved to a position where the shoulder of the slider 50 abuts (the position of the two-dot chain line shown in FIG. 1). As shown in FIG. 1, the first dentition 12 is not fixed above the passage type upper stopper 18 a of the first fastener stringer 16. Therefore, in the state where the shoulder of the slider 50 is in a position where it abuts the top stopper 18, the core portion 14 on the first fastener stringer 16 side and the second fastener stringer 17 are present in the engagement tooth insertion passage of the slider 50. It is the 2nd service tooth row 13 of the side. Since the first service tooth row 12 does not exist on the first fastener stringer 16 side, the second service tooth row 13 fixed above the passage type upper stopper 18a is not meshed. Yes.
　この、第２務歯列１３が噛合していない状態において、利用者が左右のファスナーストリンガー同士を左右方向に向けて開く力を加えると、第１ファスナーストリンガー１６の芯部１４が、スライダー５０のテープ溝を通って務歯挿通路から外れる。第１ファスナーストリンガー１６の芯部１４が、スライダー５０の務歯挿通路から外れた状態が、図１に示す状態である。 When the user applies a force to open the left and right fastener stringers in the left-right direction in a state where the second engagement tooth row 13 is not engaged, the core portion 14 of the first fastener stringer 16 is It goes out of the tooth insertion passage through the tape groove. The state in which the core portion 14 of the first fastener stringer 16 is disengaged from the engagement tooth insertion passage of the slider 50 is the state shown in FIG.
　第１ファスナーストリンガー１６がスライダー５０から外れると、スライダー５０よりも下方で噛合していた左右の第１務歯列１２及び第２務歯列１３は、上方から順に噛合が外れて、順次開離した状態となる。 When the first fastener stringer 16 is disengaged from the slider 50, the left and right first engagement tooth rows 12 and the second engagement tooth row 13 engaged below the slider 50 are disengaged sequentially from above and sequentially separated. It will be in the state.
　次に、図２～図７を用いて、本発明に係る開離嵌挿具の箱棒と、箱体と、蝶棒との関係について説明する。図２は、左右のファスナーストリンガーを開離した状態において、開離嵌挿具の箱体４０Ｂを裏面側から観察した斜視図である。図３は、開離嵌挿具の箱体４０Ｂを蝶棒３０側から観察した側面図である。図４は、開離嵌挿具における箱体４０Ｂの嵌挿部４０Ｚに蝶棒３０が嵌挿されている状態を、裏面側から観察した背面図である。図５は、箱体４０Ｂの嵌挿部４０Ｚに蝶棒が嵌挿されている状態を示す図であり、図４に示すＶ－Ｖ矢視断面図である。図６は、箱体４０Ｂの嵌挿部４０Ｚに蝶棒３０が嵌挿されている状態を示す図であり、図４に示すＶＩ－ＶＩ矢視断面図である。図７は、箱体４０Ｂの嵌挿部４０Ｚに蝶棒３０が嵌挿されている状態を示す図であり、図４に示すＶＩＩ－ＶＩＩ矢視断面図である。 Next, with reference to FIGS. 2 to 7, the relationship between the box bar, the box, and the butterfly bar of the separation / insertion tool according to the present invention will be described. FIG. 2 is a perspective view of the box body 40B of the separation / insertion tool observed from the back side in a state where the left and right fastener stringers are separated. FIG. 3 is a side view of the box body 40B of the separation / insertion tool observed from the butterfly pin 30 side. FIG. 4 is a rear view of the state in which the butterfly pin 30 is inserted into the insertion part 40Z of the box 40B in the separation / insertion tool, as observed from the back side. FIG. 5 is a view showing a state in which a butterfly stick is inserted into the insertion portion 40Z of the box 40B, and is a cross-sectional view taken along line VV shown in FIG. 6 is a view showing a state in which the butterfly stick 30 is inserted into the insertion portion 40Z of the box 40B, and is a cross-sectional view taken along the line VI-VI shown in FIG. FIG. 7 is a view showing a state in which the butterfly pin 30 is inserted into the insertion portion 40Z of the box 40B, and is a cross-sectional view taken along arrow VII-VII shown in FIG.
　図２に示すように、箱棒４０の下端には、蝶棒３０を挿抜可能に遊嵌するための四側部により形成される嵌挿部４０Ｚを形成した、箱体４０Ｂを固定してある。嵌挿部４０Ｚの箱棒４０側には、蝶棒３０を箱棒４０方向に対する位置決めを行うとともに、蝶棒３０を嵌挿部４０Ｚに嵌挿してゆく際に蝶棒３０の嵌挿方向を案内するための案内面として機能する箱棒側壁面４０Ｈを形成してある。 As shown in FIG. 2, a box 40B is fixed to the lower end of the box bar 40. The box body 40B is formed with a fitting insertion part 40Z formed by four sides for loosely fitting the butterfly stick 30. . On the side of the box bar 40 of the insertion part 40Z, the butterfly bar 30 is positioned in the direction of the box bar 40, and the insertion direction of the butterfly bar 30 is guided when the butterfly bar 30 is inserted into the insertion part 40Z. A box bar side wall surface 40H is formed which functions as a guide surface.
　嵌挿部４０Ｚにおけるクイックオープン式スライドファスナー１０のファスナーテープの一方の面である表面の内側には、蝶棒３０をスライドファスナーの表方向に対する位置決めを行うとともに、蝶棒３０を嵌挿部４０Ｚに嵌挿してゆく際に蝶棒３０の嵌挿方向を案内するための案内面として機能するための表壁面４０Ｃを、蝶棒３０の下部を表面側から覆い隠す形で形成してある。 On the inner side of the surface that is one surface of the fastener tape of the quick-open slide fastener 10 in the insertion portion 40Z, the butterfly pin 30 is positioned in the front direction of the slide fastener, and the butterfly pin 30 is attached to the insertion portion 40Z. A front wall surface 40C for functioning as a guide surface for guiding the insertion direction of the butterfly stick 30 during insertion is formed so as to cover the lower part of the butterfly stick 30 from the surface side.
　図２～図４に示すように、箱体４０Ｂにおける嵌挿部４０Ｚの最奥端には、嵌挿部４０Ｚの底部を塞ぐ底壁４０Ｇを形成してある。底壁４０Ｇは、箱体４０Ｂの最下端であって、箱棒側壁面４０Ｈの底縁から延出する形で形成してある。 As shown in FIGS. 2 to 4, a bottom wall 40G that closes the bottom of the insertion portion 40Z is formed at the innermost end of the insertion portion 40Z in the box 40B. The bottom wall 40G is the lowermost end of the box body 40B, and is formed so as to extend from the bottom edge of the box bar side wall surface 40H.
　嵌挿部４０Ｚにおけるクイックオープン式スライドファスナー１０の裏面側には、蝶棒３０をスライドファスナーの裏方向に位置決めする裏抜止突片４０Ｅが、底壁４０Ｇの側縁から突出している。なお、図２に示すクイックオープン式スライドファスナー１０においては、蝶棒３０の案内面として機能する表壁面４０Ｃが存在する側を「表面」として定義しているが、実際にクイックオープン式スライドファスナー１０を使用する状態において、これとは逆に、表壁面４０Ｃが存在する側を「裏面」として用い、裏抜止突片４０Ｅが存在する側を「表面」として使用することも可能である。すなわち、クイックオープン式スライドファスナー１０は、ファスナーテープのいずれの面も「表面」として用いることができる。 On the back surface side of the quick-open slide fastener 10 in the insertion portion 40Z, a back pull-out preventing protrusion 40E that positions the butterfly stick 30 in the back direction of the slide fastener protrudes from the side edge of the bottom wall 40G. In the quick-open slide fastener 10 shown in FIG. 2, the side on which the front wall surface 40C that functions as the guide surface of the butterfly stick 30 is defined as “surface”. On the other hand, it is also possible to use the side where the front wall surface 40C exists as the “back surface” and the side where the back removal preventing protrusion 40E exists as the “front surface”. That is, the quick open slide fastener 10 can use any surface of the fastener tape as a “surface”.
　また、図２及び図３に示すように、嵌挿部４０Ｚの第１ファスナーストリンガー１６側の側縁には、蝶棒３０を箱棒４０から離間する側に対して位置決めする離間側抜止突片４０Ｄが、表壁面４０Ｃの側縁、及び底壁４０Ｇの側縁から突出している。 Further, as shown in FIGS. 2 and 3, at the side edge on the first fastener stringer 16 side of the fitting insertion portion 40 </ b> Z, a separation-side retaining protrusion that positions the butterfly pin 30 with respect to the side away from the box rod 40. 40D protrudes from the side edge of the front wall surface 40C and the side edge of the bottom wall 40G.
　なお、図２、図４、及び図６に示す実施形態では、箱棒側壁面４０Ｈと裏抜止突片４０Ｅとの間に隔離スリット４０Ｆを形成してある。このように、箱棒側壁面４０Ｈと裏抜止突片４０Ｅとの間を直接接続せずに、隔離スリット４０Ｆを形成することによって、図７に示すように、裏抜止突片４０Ｅを外側に向けて撓みやすく構成することができる。 In the embodiment shown in FIG. 2, FIG. 4, and FIG. 6, an isolation slit 40F is formed between the box bar side wall surface 40H and the back-out preventing projection piece 40E. In this way, by forming the isolation slit 40F without directly connecting the box bar side wall surface 40H and the back-out preventing protrusion 40E, as shown in FIG. 7, the back-out preventing protrusion 40E is directed outward. And can be easily bent.
　裏抜止突片４０Ｅを外側に向けて撓みやすく構成することによって、第１務歯列１２及び第２務歯列１３同士が噛合している場合において、衣服の洗濯時等において蝶棒３０及び箱体４０Ｂに圧迫の力が加わった場合であっても、蝶棒３０が箱体４０Ｂから弱い力で外れるので、蝶棒３０及び箱体４０Ｂが破損してしまう不具合を減少させることができる。 By configuring the back-preventing protruding piece 40E to be easily bent outward, the butterfly pin 30 and the box when the clothes are washed when the first service tooth row 12 and the second service tooth row 13 are engaged with each other. Even when a pressing force is applied to the body 40B, the butterfly stick 30 is detached from the box body 40B with a weak force, so that the problem that the butterfly stick 30 and the box body 40B are damaged can be reduced.
　次に、スライダー５０の後口が箱体４０Ｂの上部に当接する位置まで、スライダー５０を下げてから、箱体４０Ｂの嵌挿部４０Ｚ内に蝶棒３０を嵌挿し、その後スライダー５０を上方に向けて移動させて、左右のファスナーストリンガー同士を閉じた状態について、図４～図７を用いて説明する。 Next, after lowering the slider 50 to a position where the rear opening of the slider 50 comes into contact with the upper portion of the box 40B, the butterfly stick 30 is inserted into the insertion portion 40Z of the box 40B, and then the slider 50 is moved upward. A state in which the left and right fastener stringers are closed by being moved toward each other will be described with reference to FIGS.
　図４～図７に示す状態では、蝶棒３０が箱体４０Ｂの嵌挿部４０Ｚに嵌挿されており、この状態で蝶棒３０は、表壁面４０Ｃによりスライドファスナーの表方向に対して位置決めされ、箱棒側壁面４０Ｈにより箱棒４０側に対して位置決めされた状態となっている。更に、蝶棒３０下端の先端部は、裏抜止突片４０Ｅによりスライドファスナーの裏方向に対して位置決めされ、離間側抜止突片４０Ｄにより箱棒４０から離間する側に対して位置決めされた状態となっている。 In the state shown in FIGS. 4 to 7, the butterfly pin 30 is inserted into the insertion portion 40Z of the box 40B. In this state, the butterfly pin 30 is positioned with respect to the front direction of the slide fastener by the front wall surface 40C. It is in a state of being positioned with respect to the box bar 40 side by the box bar side wall surface 40H. Furthermore, the tip of the lower end of the butterfly stick 30 is positioned with respect to the back direction of the slide fastener by the back pull-out preventing protrusion 40E, and is positioned with respect to the side away from the box bar 40 by the separation-side preventing protrusion 40D. It has become.
　裏抜止突片４０Ｅ及び離間側抜止突片４０Ｄは、突出高さが低い凸部として形成されているので、図５に示すように、表壁面４０Ｃ及び箱棒側壁面４０Ｈと対峙する部位において、広い開口４０Ｊが形成されている。 Since the back-out preventing protrusion 40E and the separation-side preventing protrusion 40D are formed as protrusions having a low protrusion height, as shown in FIG. 5, in the portion facing the front wall surface 40C and the box bar side wall surface 40H, A wide opening 40J is formed.
　次に、スライダー５０を下げる操作を伴わずに、噛合状態にある左右のファスナーストリンガーを即時に開裂させる手順について、以下に説明する。 Next, a procedure for immediately cleaving the right and left fastener stringers in an engaged state without an operation of lowering the slider 50 will be described below.
　先に説明したように、スライダー５０の肩口と上止め１８とが当接する位置までスライダー５０を上に移動させた後に、利用者が左右のファスナーストリンガー同士を左右方向に向けて開く力を加えると、先ず第１ファスナーストリンガー１６の芯部１４がスライダー５０のテープ溝から外れる。 As described above, after the slider 50 is moved up to a position where the shoulder of the slider 50 and the upper stopper 18 come into contact with each other, the user applies a force to open the left and right fastener stringers in the left-right direction. First, the core portion 14 of the first fastener stringer 16 is released from the tape groove of the slider 50.
　更に利用者が左右のファスナーストリンガー同士を左右方向に向けて開く力を加え続けると、スライダー５０よりも下方で噛合していた左右の第１務歯列１２及び第２務歯列１３は、上方から順に噛合が外れて、順次開離した状態となり、蝶棒３０及び箱棒４０の直上まで噛合が外れ、左右のファスナーストリンガーが蝶棒３０及び箱体４０Ｂのみにより結合している状態となる。 Further, when the user continues to apply a force to open the left and right fastener stringers in the left-right direction, the left and right first dentitions 12 and the second dentition 13 that are engaged below the slider 50 are moved upward. Are sequentially disengaged from each other and are sequentially separated, disengaged to the position just above the butterfly stick 30 and the box stick 40, and the left and right fastener stringers are joined only by the butterfly stick 30 and the box body 40B.
　更に、利用者が左右のファスナーストリンガー同士を左右方向に向けて開く力を加え続けると、裏抜止突片４０Ｅの上方に空いている広い開口４０Ｊから蝶棒３０が傾きながら外れる。この開口４０Ｊは広く空いているので、蝶棒３０を傾けることで、蝶棒３０を嵌挿部４０Ｚから容易に外すことができる。したがって、利用者が左右のファスナーストリンガー同士を左右方向に開く操作を行った場合に、軽い力で素早く蝶棒３０を箱体４０Ｂから外すことができる。更に図７に示すように、裏抜止突片４０Ｅに嵌挿部４０Ｚの外側に向けて撓む可撓性を備えることで、裏抜止突片４０Ｅを撓ませながら蝶棒３０を容易に外すことができる。 Furthermore, if the user continues to apply force to open the left and right fastener stringers in the left-right direction, the butterfly stick 30 is detached while being tilted from the wide opening 40J that is vacant above the back pull-out preventing protrusion 40E. Since this opening 40J is widely open, by tilting the butterfly pin 30, the butterfly rod 30 can be easily removed from the fitting insertion portion 40Z. Therefore, when the user performs an operation of opening the left and right fastener stringers in the left-right direction, the butterfly stick 30 can be quickly removed from the box 40B with a light force. Further, as shown in FIG. 7, by providing the back-extracting protrusion 40 </ b> E with the flexibility to bend toward the outside of the insertion portion 40 </ b> Z, the butterfly rod 30 can be easily removed while the back-extracting protrusion 40 </ b> E is bent. Can do.
　次に、蝶棒３０を箱体に嵌挿した際に、蝶棒３０をクイックオープン式スライドファスナー１０の裏方向に対して位置決めするための裏抜止突片の他の実施形態について、図８及び図９を用いて説明する。 Next, with reference to FIG. 8 and FIG. 8, another embodiment of the back-preventing protruding piece for positioning the butterfly stick 30 with respect to the reverse direction of the quick-open slide fastener 10 when the butterfly stick 30 is inserted into the box. This will be described with reference to FIG.
　図８は、箱体１４０Ｂの底壁４０Ｇの側縁から突出している裏抜止突片４０Ｅが、直接箱棒側壁面４０Ｈと接続する形で形成されている状態を示す図である。なお、図２に示した部材と同一の機能を有する部材には同一の符号を付して、その説明を省略する。 FIG. 8 is a view showing a state in which a back-preventing protrusion 40E protruding from the side edge of the bottom wall 40G of the box body 140B is formed so as to be directly connected to the box bar side wall surface 40H. In addition, the same code | symbol is attached | subjected to the member which has the same function as the member shown in FIG. 2, and the description is abbreviate | omitted.
　図２～図７に示した実施形態では、箱体４０Ｂの底壁４０Ｇの側縁から突出している裏抜止突片４０Ｅと、箱体４０Ｂの箱棒側壁面４０Ｈとの間は直接接続されておらず、その間には隔離スリット４０Ｆが形成されていた。当該隔離スリット４０Ｆを形成することで、裏抜止突片４０Ｅを嵌挿部４０Ｚの外側に向けて撓み易くすることができる。 In the embodiment shown in FIG. 2 to FIG. 7, the back-preventing protruding piece 40E protruding from the side edge of the bottom wall 40G of the box body 40B and the box bar side wall surface 40H of the box body 40B are directly connected. The isolation slit 40F was formed between them. By forming the isolation slit 40F, it is possible to make the back-out preventing projection piece 40E bend toward the outside of the fitting insertion portion 40Z.
　しかし、図８に示すように、隔離スリット４０Ｆを敢えて設けずに、裏抜止突片４０Ｅを箱棒側壁面４０Ｈ及び底壁４０Ｇの双方の裏面側の側縁から突出させる形で形成することもできる。このように、裏抜止突片４０Ｅを箱棒側壁面４０Ｈ及び底壁４０Ｇの双方の裏面側の側縁から延出させた場合であっても、裏抜止突片４０Ｅの素材や形状を適宜調節して裏抜止突片４０Ｅの可撓性を大きくすることで、嵌挿部４０Ｚから蝶棒３０を外し易く構成することができる。 However, as shown in FIG. 8, without providing the isolation slit 40F, it is also possible to form the back-out preventing projection piece 40E so as to protrude from the side edges on the back side of both the box bar side wall surface 40H and the bottom wall 40G. it can. In this way, even when the backside-preventing protruding piece 40E is extended from the side edges on the back side of both the box bar side wall surface 40H and the bottom wall 40G, the material and shape of the backside-preventing protruding piece 40E are appropriately adjusted. Then, by increasing the flexibility of the back-out preventing projection piece 40E, the butterfly stick 30 can be easily removed from the fitting insertion portion 40Z.
　図９は、裏抜止突片２４０Ｅを、箱体２４０Ｂにおける箱棒側壁面４０Ｈの裏面側端縁から嵌挿部４０Ｚ側に突片として突出させた実施形態を示す図である。なお、図２に示した部材と同一の機能を有する部材には同一の符号を付して、その説明を省略する。 FIG. 9 is a view showing an embodiment in which a back-preventing protruding piece 240E is protruded as a protruding piece from the back side edge of the box bar side wall surface 40H in the box 240B to the fitting insertion portion 40Z side. In addition, the same code | symbol is attached | subjected to the member which has the same function as the member shown in FIG. 2, and the description is abbreviate | omitted.
　図２～図８に示した実施形態では、箱体４０Ｂの底壁４０Ｇの側縁から裏抜止突片４０Ｅを上方に向けて突出させた実施形態を示したが、図９に示すように、箱体２４０Ｂにおける箱棒側壁面４０Ｈの裏面側端縁から裏抜止突片２４０Ｅを突出させても、左右のファスナーストリンガー同士を左右方向に向けて開く力を加えた際の蝶棒３０の開離を容易にすることができる。 In the embodiment shown in FIG. 2 to FIG. 8, the embodiment in which the back removal preventing protrusion 40E protrudes upward from the side edge of the bottom wall 40G of the box body 40B is shown, but as shown in FIG. Even if the back removal preventing protrusion 240E protrudes from the back side edge of the box bar side wall face 40H in the box 240B, the butterfly stick 30 is separated when a force is applied to open the left and right fastener stringers in the left-right direction. Can be made easier.
　図９に示す実施形態では、裏抜止突片２４０Ｅと、箱体２４０Ｂの底壁４０Ｇとの間に隔離スリット４０Ｆを形成することにより、裏抜止突片２４０Ｅを嵌挿部４０Ｚの外側に向けて撓み易くして、嵌挿部４０Ｚから蝶棒３０を外し易く構成してある。なお、図９に示す実施形態では、裏抜止突片２４０Ｅと、箱体２４０Ｂの底壁４０Ｇとの間に隔離スリット４０Ｆを形成した実施形態を示してあるが、離間側抜止突片４０Ｄと、箱体２４０Ｂの底壁４０Ｇとの間に隔離スリットを形成することもできる。 In the embodiment shown in FIG. 9, by forming an isolation slit 40F between the back extraction preventing piece 240E and the bottom wall 40G of the box 240B, the back extraction preventing piece 240E faces the outside of the insertion portion 40Z. It is easy to bend and is configured to easily remove the butterfly stick 30 from the fitting portion 40Z. In the embodiment shown in FIG. 9, an embodiment is shown in which an isolation slit 40F is formed between the back-out preventing projection piece 240E and the bottom wall 40G of the box 240B. An isolation slit can also be formed between the bottom wall 40G of the box 240B.
　次に、本発明に係る開離嵌挿具の箱体に、クイックオープン式スライダーを組み合わせた他の実施形態について、図１０を用いて説明する。 Next, another embodiment in which a quick-open type slider is combined with the box body of the break-fitting insert according to the present invention will be described with reference to FIG.

And a puller attachment column 58 having an opening part in which a puller shaft part 59A serving as a rotation center of the puller 59 is freely fitted.
　上翼片５２及び下翼片５３の両側縁部には、スライダー３５０の移動に伴い第１務歯列１２及び第２務歯列１３同士を噛み合わせてゆくために、双方の務歯同士を引き合わせるフランジ５０Ｆ、５０Ｔ、５０Ｕを延設してある。上翼片５２及び下翼片５３のフランジ５０Ｆ同士が対向する隙間部分、及び、フランジ５０Ｔとフランジ５０Ｕとが対向する隙間部分には、第１ファスナーストリンガー１６及び第２ファスナーストリンガー１７のファスナーテープを挿通させるためのテープ溝が空けられている。 In order to engage the first service tooth row 12 and the second service tooth row 13 with the movement of the slider 350, both side teeth of the upper blade piece 52 and the lower blade piece 53 are connected to each other. The flanges 50F, 50T, and 50U to be brought together are extended. Fastener tapes of the first fastener stringer 16 and the second fastener stringer 17 are attached to a gap portion where the flanges 50F of the upper blade piece 52 and the lower blade piece 53 face each other and a gap portion where the flange 50T and the flange 50U face each other. A tape groove is made for insertion.
　フランジ５０Ｆ同士が対向する部分に形成されているテープ溝は、図１２の側面図に示されるように、肩口側から後口側まで一定の隙間ｈ'で形成してある。このテープ溝は、第２ファスナーストリンガー１７のファスナーテープを挿通させるために空けられている隙間であるので、テープ溝の隙間ｈ'は、ファスナーテープの厚さよりも僅かに広く、第２務歯列１３の厚さよりも狭く、通常のスライダーと同様の隙間に設定されている。 The tape groove formed in the portion where the flanges 50F face each other is formed with a constant gap h ′ from the shoulder opening side to the rear opening side, as shown in the side view of FIG. Since this tape groove is a gap that is opened to allow the fastener tape of the second fastener stringer 17 to pass therethrough, the gap h ′ of the tape groove is slightly wider than the thickness of the fastener tape, and the second dentition It is narrower than the thickness of 13 and is set to the same gap as a normal slider.
　これに対し、フランジ５０Ｔ、５０Ｕが対向する隙間部分のテープ溝は、図１２の側面図に示されるように、肩口側におけるフランジ５０Ｔの延設高さを、中央部の延設高さよりも低くした傾斜形状に設定してある。こうすることで、肩口側のテープ溝の隙間Ｈを幅広に設定するとともに、後口側のテープ溝の隙間ｈを狭く設定してある。 On the other hand, as shown in the side view of FIG. 12, the tape groove in the gap portion where the flanges 50T and 50U face each other has an extension height of the flange 50T on the shoulder opening side lower than the extension height of the center portion. The inclined shape is set. By doing so, the gap H of the shoulder groove side tape groove is set wide, and the gap h of the tape slot on the rear opening side is set narrow.
　なお、図１２に示す実施形態では、後口側のテープ溝の隙間ｈを、フランジ５０Ｆ側のテープ溝の隙間ｈ'よりも広くなるように設定してあるが、上翼片５２の可撓性（後段にて説明。）に応じて、後口側のテープ溝の隙間ｈを、フランジ５０Ｆ側のテープ溝の隙間ｈ'程度まで狭く設定することも可能である。また、上翼片５２の可撓性に応じて、テープ溝の隙間を一定の隙間に設定することもできる。 In the embodiment shown in FIG. 12, the gap h of the tape groove on the rear opening side is set to be wider than the gap h ′ of the tape groove on the flange 50F side. Depending on the characteristics (explained later), it is possible to set the gap h of the tape groove on the rear opening side as narrow as about the gap h ′ of the tape groove on the flange 50F side. Further, according to the flexibility of the upper blade piece 52, the gap of the tape groove can be set to a constant gap.
　図１２に示した実施形態では、スライダー３５０の下翼片５３から延設しているフランジ５０Ｕは、肩口側から後口まで一定の低い延設高さに設定されている。これに対し、上翼片５２から延設しているフランジ５０Ｔは、肩口側の延設高さが中央部の延設高さよりも低い傾斜形状に設定されている。なお、他の実施形態として、図１２に示す実施形態とは逆に、上翼片５２から延設しているフランジを、肩口側から後口まで一定の低い延設高さに設定し、下翼片５３から延設しているフランジを、肩口側の延設高さが、中央部の延設高さよりも低い傾斜形状に設定することもできる。 In the embodiment shown in FIG. 12, the flange 50U extending from the lower wing piece 53 of the slider 350 is set to a certain low extension height from the shoulder opening side to the rear opening. On the other hand, the flange 50T extending from the upper wing piece 52 is set to have an inclined shape in which the extension height on the shoulder opening side is lower than the extension height of the central portion. As another embodiment, contrary to the embodiment shown in FIG. 12, the flange extending from the upper wing piece 52 is set to a certain low extension height from the shoulder opening side to the rear opening, The flange extending from the wing piece 53 can also be set to an inclined shape in which the extension height on the shoulder opening side is lower than the extension height of the central portion.
　次に、図１３～図１５を用いて、本実施形態によるスライダー３５０から、務歯とともにファスナーストリンガーを外すときの可撓性について説明する。図１３は、図１０に示したＸＩＩＩ－ＸＩＩＩ矢視断面図であり、図１４は、図１０に示したＸＩＶ－ＸＩＶ矢視断面図である。また、図１５は、図１０に示したＸＶ－ＸＶ矢視断面図である。なお、図１０及び図１１に示した部分と同じ部分については、同一の符号を付してその説明を省略する。 Next, the flexibility when the fastener stringer is removed together with the service teeth from the slider 350 according to this embodiment will be described with reference to FIGS. 13 is a cross-sectional view taken along arrow XIII-XIII shown in FIG. 10, and FIG. 14 is a cross-sectional view taken along arrow XIV-XIV shown in FIG. 15 is a cross-sectional view taken along arrow XV-XV shown in FIG. Note that the same parts as those shown in FIGS. 10 and 11 are denoted by the same reference numerals and description thereof is omitted.
　図１３～図１５は、それぞれスライダー３５０の務歯案内通路及び第１ファスナーストリンガー１６の断面図であり、務歯案内通路の内部から肩口側に向けて観察した断面図である。図１３に示す断面は、スライダー３５０の肩口に近い部分の断面図であるので、フランジ５０Ｔの延設高さが最も低く示されている。図１４に示す断面は、図１３で示す位置よりも後口側に少し近づいているために、図１３に示す状態よりもフランジ５０Ｔの延設高さが高く示されている。図１５に示す断面では、更に後口側に近づいているために、図１４に示す状態よりもフランジ５０Ｔの延設高さが高く示されている。 FIGS. 13 to 15 are cross-sectional views of the fixed tooth guide passage of the slider 350 and the first fastener stringer 16, respectively, and are cross-sectional views observed from the inside of the fixed tooth guide passage toward the shoulder opening side. Since the cross section shown in FIG. 13 is a cross sectional view of the portion close to the shoulder opening of the slider 350, the extending height of the flange 50T is shown to be the lowest. Since the cross section shown in FIG. 14 is slightly closer to the rear opening side than the position shown in FIG. 13, the extending height of the flange 50T is shown higher than the state shown in FIG. In the cross section shown in FIG. 15, the extension height of the flange 50 </ b> T is shown higher than in the state shown in FIG. 14 because it is closer to the rear opening side.
　このように、フランジ５０Ｔの延設高さは、スライダー３５０の後口方向に近づくにつれて高くなるように設定してあるので、スライダー３５０の移動に伴ってスライダー３５０の肩口から導入した分離状態の第１務歯列１２を、対峙する第２務歯列１３と噛み合わせてゆくために、フランジ５０Ｔの延設高さが高い部分において、双方の務歯同士を引き合わせることができる。 As described above, the extending height of the flange 50T is set so as to increase as it approaches the rear opening direction of the slider 350. Therefore, the first height in the separated state introduced from the shoulder opening of the slider 350 as the slider 350 moves. In order to engage the first service tooth row 12 with the second service tooth row 13 facing each other, both of the service teeth can be brought together at a portion where the extending height of the flange 50T is high.
　また、本発明に係るスライダー３５０は、結晶性ポリアミド樹脂等の可撓性を備える樹脂成形品で成形することが好ましい。可撓性を備える素材を用いることによって、スライダー３５０の上翼片５２のフランジ５０Ｔ、５０Ｕ側を、図１３の二点鎖線で示す表方向に撓ませることができる。一方、第１及び第２務歯列１２、１３の素材は、前記結晶性ポリアミド樹脂等よりも弾性率の高いポリアセタール樹脂等を使うことが好ましい。スライダー３５０及び第１及び第２務歯列１２、１３の材質は、前述の例に限るものではないが、少なくともスライダー３５０の材質の弾性率は、第１及び第２務歯例１２、１３の材質の弾性率より低く設定することが好ましい。 Also, the slider 350 according to the present invention is preferably molded from a resin molded product having flexibility such as crystalline polyamide resin. By using a flexible material, the flanges 50T and 50U side of the upper wing piece 52 of the slider 350 can be bent in the front direction indicated by a two-dot chain line in FIG. On the other hand, it is preferable to use a polyacetal resin or the like having a higher elastic modulus than the crystalline polyamide resin or the like as the material of the first and second tooth arrangements 12 and 13. The material of the slider 350 and the first and second tooth arrangements 12 and 13 is not limited to the above example, but at least the elastic modulus of the material of the slider 350 is that of the first and second tooth arrangements 12 and 13. It is preferable to set it lower than the elastic modulus of the material.
　次に、閉鎖状態にあるクイックオープン式スライドファスナー３１０を瞬時に開離させる操作を行った際における、スライダー３５０と第１務歯列１２との関係について説明する。スライダー３５０の側方において、左右の第１ファスナーストリンガー１６及び第２ファスナーストリンガー１７を左右方向に向けて開く力を加えると、第１務歯列１２の最も肩口側の務歯が、延設高さが低く設定されている肩口側のフランジ５０Ｔ、５０Ｕの間のテープ溝に入り込もうとする。このとき、第１務歯列１２の最も肩口側の務歯が、フランジ５０Ｔ及び上翼片５２の隅部を上方に撓ませようとする。その結果、肩口側のテープ溝が拡幅されて、テープ溝に第１務歯列１２が食い込んだ状態となる。 Next, the relationship between the slider 350 and the first dentition 12 when an operation for instantaneously releasing the quick-open slide fastener 310 in the closed state is performed will be described. When a force to open the left and right first fastener stringers 16 and the second fastener stringers 17 in the left-right direction is applied to the side of the slider 350, the engagement tooth on the most shoulder side of the first engagement tooth row 12 is extended to the height Tries to enter the tape groove between the flanges 50T and 50U on the shoulder opening side where the height is set low. At this time, the engagement tooth closest to the shoulder opening of the first engagement tooth row 12 tends to bend the corners of the flange 50T and the upper blade piece 52 upward. As a result, the shoulder groove side tape groove is widened, and the first dentition 12 is cut into the tape groove.
　更に、左右の第１ファスナーストリンガー１６及び第２ファスナーストリンガー１７を左右方向に向けて開く力を加え続けると、テープ溝に食い込んでいた第１務歯列１２の務歯がフランジ５０Ｔ、５０Ｕを乗り越えて、図１３の仮想線で示すように、完全にスライダーの務歯案内通路から外れる。 Furthermore, if the force that opens the left and right first fastener stringers 16 and the second fastener stringers 17 in the left-right direction is continuously applied, the service teeth of the first service tooth row 12 that have bite into the tape groove get over the flanges 50T and 50U. Thus, as shown by the phantom line in FIG.
　図１３に示す実施形態では、上翼片５２のフランジ５０Ｔ側に可撓性を備えている実施形態を示しているが、下翼片５３のフランジ５０Ｕ側を裏方向に撓ませることができるように可撓性を備えてもよいし、上翼片５２及び下翼片５３の双方に可撓性を備えるように構成することができる。 In the embodiment shown in FIG. 13, an embodiment is shown in which the flange 50T side of the upper wing piece 52 is flexible. However, the flange 50U side of the lower wing piece 53 can be bent backward. The upper wing piece 52 and the lower wing piece 53 may be provided with flexibility.
　また、左右の第１ファスナーストリンガー１６及び第２ファスナーストリンガー１７を左右方向に向けて開く力を加えた際に、フランジ５０Ｔ、５０Ｕが、第１務歯列１２に乗り上がり易くなるようにするために、当初フランジ５０Ｔ、５０Ｕと第１務歯列１２とが当接する乗上部５０Ｖのフランジ５０Ｔ、５０Ｕの隅角部に、Ｃ面取又はＲ面取を形成するようにしてもよい。また、第１務歯列１２の隅角部に、Ｃ面取又はＲ面取を形成することもできる。 Further, when applying a force to open the left and right first fastener stringers 16 and the second fastener stringers 17 in the left-right direction, the flanges 50T and 50U can easily get on the first service tooth row 12. In addition, C chamfering or R chamfering may be formed at the corners of the flanges 50T and 50U of the riding portion 50V where the initial flanges 50T and 50U and the first engagement tooth row 12 abut. In addition, C chamfering or R chamfering can be formed at the corners of the first service tooth row 12.
　次に、図１６～図１９を用いて、閉じている左右のファスナーストリンガーを、スライダーの摺動に依らず素早く開く操作を行った際の、第１務歯列１２の動きについて説明する。 Next, using FIG. 16 to FIG. 19, the movement of the first tooth set 12 when the closed left and right fastener stringers are quickly opened regardless of the sliding of the slider will be described.
　図１６は、図１３に示したスライダー３５０の肩口に近い部分において、スライダー３５０の務歯案内通路に存在する第１務歯列１２のうち、肩口に最も近い最初の務歯１２－１がフランジ５０Ｔ、５０Ｕの対向面間のテープ溝に食い込んだ状態を示す平面断面図である。また、図１７は、図１４に示した断面付近において２番目の務歯１２－２がテープ溝に食い込んでいる状態を示す平面断面図である。図１８は、図１７に示した状態から、更に噛合していた３番目の務歯１２－３が一つ分離して、その分離した務歯がテープ溝に新たに食い込んだ状態を示す平面断面図である。図１９は、スライダー３５０の務歯案内通路に入っていた全ての務歯の噛合が外れて、左右の第１ファスナーストリンガー１６と第２ファスナーストリンガー１７とが開離した状態を示す図である。 FIG. 16 shows that in the portion close to the shoulder mouth of the slider 350 shown in FIG. 13, the first tooth 12-1 closest to the shoulder mouth among the first tooth teeth 12 existing in the tooth guide passage of the slider 350 is the flange. It is plane sectional drawing which shows the state which digged into the tape groove | channel between the opposing surfaces of 50T and 50U. FIG. 17 is a plan sectional view showing a state where the second engagement tooth 12-2 is biting into the tape groove in the vicinity of the section shown in FIG. 18 is a cross-sectional plan view showing a state in which the third engagement tooth 12-3 that has been further engaged is separated from the state shown in FIG. 17, and the separated engagement tooth is newly biting into the tape groove. FIG. FIG. 19 is a view showing a state in which all the engagement teeth that have entered the engagement tooth guide passage of the slider 350 are disengaged and the left and right first fastener stringers 16 and the second fastener stringers 17 are separated.
　例えば、衣服の左前身頃の中央側の側縁に第１ファスナーストリンガー１６を縫着し、右前身頃の中央側の側縁に第２ファスナーストリンガー１７を縫着し、第１務歯列１２及び第２務歯列１３が噛合状態にある状態から、左右の第１ファスナーストリンガー１６と第２ファスナーストリンガー１７とを瞬時に開離させる場合について説明する。 For example, the first fastener stringer 16 is sewn on the central side edge of the left front body of the garment, and the second fastener stringer 17 is sewn on the central side edge of the right front body. The case where the left and right first fastener stringers 16 and the second fastener stringers 17 are instantaneously separated from the state where the two-tooth set 13 is in an engaged state will be described.
　先ず、第１務歯列１２及び第２務歯列１３を噛合状態にしておく。そして、スライダー３５０の側方において、左右の第１ファスナーストリンガー１６及び第２ファスナーストリンガー１７に対して、図１７にて矢印で示すようにそれぞれを左右方向に開く力を加える。 First, the first dentition 12 and the second dentition 13 are in mesh. Then, on the side of the slider 350, a force is applied to the left and right first fastener stringers 16 and the second fastener stringers 17 to open the left and right directions as indicated by arrows in FIG.
　すると、図１６に示すように、最初に第１ファスナーストリンガー１６の１番目の務歯１２－１がスライダー３５０の肩口に近い部分において、フランジ５０Ｔ側のテープ溝に食い込んだ状態となる。このとき、可撓性を備える上翼片５２が表方向に撓んでおり、テープ溝が拡幅されている。 Then, as shown in FIG. 16, first, the first engagement tooth 12-1 of the first fastener stringer 16 is in a state of being bitten into the tape groove on the flange 50T side at a portion close to the shoulder opening of the slider 350. At this time, the flexible upper wing piece 52 is bent in the front direction, and the tape groove is widened.
　図１６に示す状態から、更に左右の第１ファスナーストリンガー１６及び第２ファスナーストリンガー１７を左右方向に向けて開き続けると、更に上翼片５２が表方向に撓んで、食い込んだ務歯がテープ溝を更に拡幅する。すると、図１７に示すように、連接されている２番目の務歯１２－２がフランジ５０Ｔ側のテープ溝に食い込んだ状態となる。 When the first fastener stringer 16 and the second fastener stringer 17 on the left and right sides are further opened in the left-right direction from the state shown in FIG. 16, the upper wing piece 52 is further bent in the front direction, and the engaged tooth is a tape groove. Is further widened. Then, as shown in FIG. 17, the connected second engagement teeth 12-2 are in a state where they are bitten into the tape groove on the flange 50T side.
　図１７に示す状態から、更に左右の第１ファスナーストリンガー１６及び第２ファスナーストリンガー１７を左右方向に向けて開くと、テープ溝に食い込んでいる２番目の務歯１２－２が上翼片５２を表方向に撓ませて、テープ溝が更に拡幅される。そして、第１務歯列１２及び第２務歯列１３の務歯のうち、噛合状態にあった務歯１２－３が、図１８に示すように、噛合相手の務歯から離間してゆき、同時に第１務歯列１２の務歯１２－３の一部がフランジ５０Ｔ、５０Ｕの間のテープ溝に食い込んだ状態となる。 When the left and right first fastener stringers 16 and second fastener stringers 17 are further opened in the left-right direction from the state shown in FIG. 17, the second service teeth 12-2 biting into the tape groove cause the upper wing piece 52 to move. The tape groove is further widened by bending in the front direction. Then, the engagement teeth 12-3 in the meshing state among the engagement teeth of the first engagement tooth row 12 and the second engagement tooth row 13 are separated from the engagement engagement teeth as shown in FIG. At the same time, a part of the service teeth 12-3 of the first service tooth row 12 is in a state of being bitten into the tape groove between the flanges 50T and 50U.
　図１８に示す状態から、更に左右の第１ファスナーストリンガー１６及び第２ファスナーストリンガー１７を左右方向に向けて開き続けると、食い込んだ務歯１２－３がテープ溝を更に拡幅する。そして次に、スライダー３５０の務歯案内通路内において噛合していた務歯１２－４の噛合が外れる。このように、スライダー３５０の務歯案内通路内に存在していた複数の務歯１２－１～１２－４が、肩口側から順番にスライダー３５０のフランジ５０Ｔ、５０Ｕの間のテープ溝を通過して、最終的に第１務歯列１２がスライダー３５０の務歯案内通路から完全に外れる。第１務歯列１２がスライダー３５０の務歯案内通路から外れると、務歯を噛み込んでいた上翼片５２の撓み（弾性変形）が戻り、元の自由位置（図１３の実線で示す位置）まで戻る。 18, when the left and right first fastener stringers 16 and the second fastener stringer 17 are continuously opened in the left and right directions, the engaged tooth 12-3 further widens the tape groove. Then, the engagement of the engagement tooth 12-4 that has been engaged in the engagement tooth guide passage of the slider 350 is released. As described above, the plurality of service teeth 12-1 to 12-4 existing in the service tooth guide passage of the slider 350 pass through the tape groove between the flanges 50T and 50U of the slider 350 in order from the shoulder opening side. Finally, the first tooth set 12 is completely removed from the tooth guide passage of the slider 350. When the first engagement tooth row 12 is disengaged from the engagement tooth guide passage of the slider 350, the deflection (elastic deformation) of the upper wing piece 52 that has engaged the engagement teeth returns, and the original free position (the position indicated by the solid line in FIG. )
　第１務歯列１２がスライダーから外れると、スライダー３５０よりも下方で噛合していた左右の第１務歯列１２及び第２務歯列１３は、上方から順に噛合が外れて、図１９に示すように、開離した状態となる。更に左右の第１務歯列１２及び第２務歯列１３を開離させてゆくと、蝶棒３０が箱体４０Ｂから抜けて、左右の第１ファスナーストリンガー１６及び第２ファスナーストリンガー１７が完全に開離した状態となる。 When the first service tooth row 12 is disengaged from the slider, the left and right first service tooth rows 12 and the second service tooth row 13 engaged below the slider 350 are disengaged in order from above, and FIG. As shown, it is in a separated state. When the left and right first dentitions 12 and the second dentition 13 are further separated, the butterfly pin 30 comes out of the box 40B, and the left and right first fastener stringers 16 and second fastener stringers 17 are completely removed. It will be in the state opened to.
　一旦完全に開離した左右の第１ファスナーストリンガー１６及び第２ファスナーストリンガー１７を、再び噛合状態にする場合について説明する。この場合には、先ずスライダー３５０を第２ファスナーストリンガー１７の最下位まで下げて、箱体４０Ｂとスライダー３５０の後口とを当接させておく。 A case will be described in which the left and right first fastener stringers 16 and second fastener stringers 17 once completely separated are brought into the meshing state again. In this case, first, the slider 350 is lowered to the lowest position of the second fastener stringer 17, and the box 40B and the rear opening of the slider 350 are brought into contact with each other.
　次に、第１ファスナーストリンガー１６をスライダー３５０の左側の肩口から挿入してゆき、蝶棒３０の下端部が箱体４０Ｂの嵌挿部４０Ｚ（図２参照。）に嵌挿するまで押し下げる。蝶棒３０を下げる方向に力を加え続けると、最終的に箱棒４０の第２係止部４４に蝶棒３０の第１係止部３４が当接する。この、蝶棒３０を下端まで嵌挿した状態においてスライダー３５０をスライドファスナーの上方に向けて引き上げる操作を行うと、第１務歯列１２と第２務歯列１３とが噛合してスライダー３５０の後口から出てくる。すると、衣服の左前身頃と右前身頃を閉じることができ、双方の前身頃同士を結合させることができる。 Next, the first fastener stringer 16 is inserted from the left shoulder of the slider 350, and is pushed down until the lower end of the butterfly pin 30 is inserted into the insertion portion 40Z (see FIG. 2) of the box 40B. When a force is continuously applied in the direction of lowering the butterfly stick 30, the first locking portion 34 of the butterfly stick 30 finally comes into contact with the second locking portion 44 of the box bar 40. If the slider 350 is pulled up above the slide fastener while the butterfly pin 30 is inserted to the lower end, the first engagement tooth row 12 and the second engagement tooth row 13 are engaged with each other. Come out from the back. Then, the left front body and the right front body of clothing can be closed, and both front bodies can be combined.
　なお、図１２に示した実施形態では、スライダー３５０の下翼片５３から延設しているフランジ５０Ｕは、肩口側から後口まで一定の低い延設高さに設定されており、上翼片５２から延設しているフランジ５０Ｔは、肩口側の延設高さが中央部の延設高さよりも低い傾斜形状に設定されている。 In the embodiment shown in FIG. 12, the flange 50U extending from the lower wing piece 53 of the slider 350 is set to a constant low extension height from the shoulder opening side to the rear opening. The flange 50T extending from 52 is set to have an inclined shape in which the height at the shoulder opening is lower than the height at the center.
　この他にも、以下に示すようにスライダーのフランジを形成することによって、肩口側のテープ溝の間隙Ｈを幅広に設定し、後口側のテープ溝の間隙ｈを狭く設定することができる。 In addition, by forming the flange of the slider as shown below, the gap H of the tape groove on the shoulder opening side can be set wide, and the gap h of the tape groove on the rear opening side can be set narrow.
　例えば、図１１に示したスライダー３５０の下翼片５３から延設しているフランジ５０Ｕを廃止し、上翼片５２から延設しているフランジ５０Ｔの延設高さを全体に嵩上げすることによって、肩口側のテープ溝の間隙Ｈを幅広に設定して、後口側のテープ溝の間隙ｈを狭く設定することもできる。 For example, the flange 50U extending from the lower wing piece 53 of the slider 350 shown in FIG. 11 is abolished, and the extending height of the flange 50T extending from the upper wing piece 52 is raised to the whole. The gap H of the shoulder groove side tape groove can be set wide and the gap h of the tape slot on the rear opening side can be set narrow.
　また逆に、スライダーの上翼片から延設しているフランジを廃止し、下翼片から延設しているフランジの形状を、肩口側の延設高さが中央部の延設高さよりも低い傾斜形状に設定することによって、肩口側のテープ溝の間隙Ｈを幅広に設定して、後口側のテープ溝の間隙ｈを狭く設定することもできる。 Conversely, the flange extending from the upper wing piece of the slider is abolished, and the shape of the flange extending from the lower wing piece is changed so that the extension height on the shoulder opening side is higher than the extension height at the center. By setting it to a low inclined shape, the gap H of the tape groove on the shoulder opening side can be set wide and the gap h of the tape groove on the rear opening side can be set narrow.
　また、この他にも、スライダーの上翼片及び下翼片から延設している双方のフランジについて、肩口側の延設高さが中央部の延設高さよりも低い傾斜形状となるように設定することにより、肩口側のテープ溝の間隙Ｈを幅広に設定して、後口側のテープ溝の間隙ｈを狭く設定することもできる。 In addition, for both flanges extending from the upper wing piece and the lower wing piece of the slider, the extension height on the shoulder side is an inclined shape lower than the extension height of the central portion. By setting, the gap H of the tape groove on the shoulder opening side can be set wide, and the gap h of the tape groove on the rear opening side can be set narrow.
　また、フランジの肩口側の延設高さが中央部の延設高さよりも低い傾斜形状を、フランジの一部のみに形成し、残りの部分を上翼片又は下翼片と平行に形成することもできる。また、上記の実施形態とは逆に、フランジの後口側の延設高さが中央部の延設高さよりも低くなる傾斜形状を、フランジに形成することもできる。フランジの後口側の延設高さを、中央部の延設高さよりも低い傾斜形状に形成することによって、後口側からテープ挿通路を拡開させて、務歯列をスライダーから外すことが容易となる。 Further, an inclined shape in which the extension height on the shoulder opening side of the flange is lower than the extension height of the central portion is formed only on a part of the flange, and the remaining part is formed in parallel with the upper wing piece or the lower wing piece. You can also. In contrast to the above-described embodiment, an inclined shape in which the extension height on the rear opening side of the flange is lower than the extension height of the central portion can be formed on the flange. By forming the extended height of the rear opening side of the flange into an inclined shape lower than the extending height of the central part, the tape insertion path is expanded from the rear opening side, and the service tooth row is removed from the slider. Becomes easier.
　また、フランジの肩口側の延設高さが中央部の延設高さよりも低い傾斜形状と、フランジの後口側の延設高さが中央部の延設高さよりも低い傾斜形状とを併用したフランジを用いることで、尻合わせ又は頭合わせにより複数のスライダーを対向して配置したスライドファスナーの分離用に用いることができる。 In addition, the slant shape with the extension height on the shoulder opening side of the flange lower than the extension height of the central portion and the slant shape with the extension height on the rear mouth side of the flange lower than the extension height of the central portion are used in combination. By using the flange, it can be used for separation of a slide fastener in which a plurality of sliders are arranged to face each other by tail-to-face or head-to-head alignment.
