After inserting and fixing the butterfly pin attached to the lower end of another fastener stringer from the shoulder of the slider inserted through this fastener stringer, while holding the lower end of the fastener stringer attached with the butterfly pin, move the slider in the closing direction. Since it has to be operated, it is difficult to operate the slider with one hand, and the fastener stringer with a butterfly stick accompanying the start of the slider also slides with the slider and the fastener element cannot be engaged.
 また、特許文献1に示す開き具は、サイドオープン型であるから、スライダーの肩口からファスナーストリンガーを挿入することはできない。スライダーによる閉鎖操作はスライダーの側面から結合片を挿入して行う。従ってスライダーの側面を利用する手段しかなく、操作性が極めて悪い。さらに特許文献2に示された開き具は、ファスナーストリンガーの閉鎖、開放操作は、スライダーの肩口を利用する手段、また側面を利用する手段ができるので、その利便性がよい開き具であるが、欠点は左右のファスナーストリンガーを閉鎖する際、必ず嵌込体を取り付けたファスナーストリンガーを把持しなければならないので、片手でスライダーを操作すると、スライダーの始動と同時に嵌込体を取り付けたファスナーストリンガーも始動し、ファスナーエレメントは噛合できない状態となり、再度最初から操作をしなおす必要があり、不便である。 Moreover, since the opening tool shown in Patent Document 1 is a side open type, a fastener stringer cannot be inserted from the shoulder of the slider. The closing operation by the slider is performed by inserting a coupling piece from the side of the slider. Therefore, there is only means for using the side surface of the slider, and the operability is extremely poor. Furthermore, the opening device shown in Patent Document 2 is a convenient opening device because the closing and opening operation of the fastener stringer can be performed by means of using the shoulder of the slider and means of using the side surface. The disadvantage is that when closing the left and right fastener stringers, you must always hold the fastener stringer with the insert attached, so if you operate the slider with one hand, the fastener stringer with the insert attached will start at the same time as the slider starts. However, the fastener element cannot be engaged, and it is necessary to re-operate from the beginning, which is inconvenient.

 この発明におけるスライドファスナー用開き具1は、図1に示すように、枢支体2と差込体3との2部材から形成され、これにスライダー10が加わって開き具1を操作することができる。枢支体2と差込体3とをファスナーテープ5に設置するには、ファスナーテープ5の端部にファスナーエレメント6が存在しないスペース部分を作り、このスペース部分に補強テープ8を貼着し、この補強テープ8の上にファスナーエレメント6に連続して枢支体2および差込体3を樹脂を用いて射出成形手段によって、ファスナーテープ5の側縁に一体成形する。 As shown in FIG. 1, the slide fastener opening device 1 according to the present invention is formed of two members, a pivotal support body 2 and an insertion body 3, and a slider 10 is added thereto to operate the opening device 1. it can. In order to install the pivot body 2 and the insertion body 3 on the fastener tape 5, a space portion where the fastener element 6 does not exist is formed at the end portion of the fastener tape 5, and the reinforcing tape 8 is attached to the space portion. On the reinforcing tape 8, the pivot body 2 and the insertion body 3 are formed integrally with the fastener element 6 on the side edge of the fastener tape 5 by injection molding means using resin.
 枢支体2は、スライダー10を嵌挿し保持できる保持部21を設け、この保持部21の内部に凹状の凹溝22を設ける。凹溝22は、スライダー10の上翼板および下翼板と対面する保持部21の表面板35と裏面板36および底部24によって囲まれ、ファスナーテープ5の長手方向に向って形成される。凹溝22の端部すなわち下端に肉厚の厚いJ字状の枢支部30を連設して、挿入板41に設けた枢軸43を嵌入する。枢支部30の先端には凹溝22に連続して、挿入板41の先端が挿入できるようにスリット31を設ける。また凹溝22内には、図5に示すように表裏の内面23に中心へ向って突出する突出部25を設けて係合部20を形成する。この突出部25の平面的形状は、図4に示すように突出部25は凹溝22の入口に面した先端を幅狭く、底部24の基部32は幅広く、上面26は底部24に対し直角状であり、下面27は斜面に形成する。 The pivotal support body 2 is provided with a holding portion 21 in which the slider 10 can be inserted and held, and a concave groove 22 is provided inside the holding portion 21. The concave groove 22 is surrounded by the front plate 35, the back plate 36 and the bottom 24 of the holding portion 21 facing the upper blade and the lower blade of the slider 10, and is formed in the longitudinal direction of the fastener tape 5. A thick J-shaped pivot 30 is connected to the end of the concave groove 22, that is, the lower end, and a pivot 43 provided on the insertion plate 41 is inserted. A slit 31 is provided at the distal end of the pivotal support portion 30 so as to be continuous with the concave groove 22 so that the distal end of the insertion plate 41 can be inserted. Further, in the concave groove 22, as shown in FIG. 5, a protruding portion 25 that protrudes toward the center is provided on the inner surface 23 of the front and back surfaces to form the engaging portion 20. As shown in FIG. 4, the planar shape of the projecting portion 25 is such that the projecting portion 25 has a narrow front end facing the entrance of the concave groove 22, the base portion 32 of the bottom portion 24 is wide, and the upper surface 26 is perpendicular to the bottom portion 24. The lower surface 27 is formed on a slope.
 一方、差込体3は平板状を呈す形態で、挿入板41は凹窩部45によって区切られた縁部44には、凹状の凹陥部42を設けて被係止部40を形成し、枢支体2の凹溝22内に形成した突出部25による係合部20を嵌入できるように形成する。挿入板41の先端側にはファスナーエレメント6と同厚の枢軸43を表裏へ突設し、挿入板41はスライダー10の肩口15および表裏のフランジ12間から挿入することができるが、枢軸43はスライダー10の肩口15から差し込まれ、スライダー10内では表裏のフランジ12間からは抜脱することはできない。 On the other hand, the insertion body 3 has a flat plate shape, and the insertion plate 41 is provided with a concave recessed portion 42 at the edge portion 44 delimited by the concave portion 45 to form a locked portion 40. It forms so that the engaging part 20 by the protrusion part 25 formed in the concave groove 22 of the support body 2 can be inserted. A pivot 43 having the same thickness as that of the fastener element 6 is provided on the front and back of the insertion plate 41. The insertion plate 41 can be inserted from between the shoulder 15 of the slider 10 and the flange 12 on the front and back. It is inserted from the shoulder opening 15 of the slider 10 and cannot be removed from between the front and back flanges 12 in the slider 10.
 この開き具1の使用態様は、最初にスライダー10を図2に示すように、枢支体2の枢支部30に当接して固定し、この固定されたスライダー10の肩口15から挿入板41を差し込み、この際、枢軸43はファスナーエレメント6と同厚なのでスライダー10のエレメントガイド溝14を挿通することはできるが、表裏のフランジ12間からは抜脱することはできない。次に図3に示すように、挿入板41は最後まで差し込まれ、枢軸43をJ字状の枢支部30に嵌入するとともに、突出部25による係合部20の先端を、挿入板41の縁部44に形成された凹陥部42による被係合部40に重合する形態で停止する。 As shown in FIG. 2, the opening device 1 is used by first abutting and fixing the slider 10 in contact with the pivot 30 of the pivot 2 and inserting the insertion plate 41 from the shoulder 15 of the fixed slider 10. At this time, since the pivot 43 has the same thickness as the fastener element 6, it can be inserted through the element guide groove 14 of the slider 10, but cannot be removed from between the front and back flanges 12. Next, as shown in FIG. 3, the insertion plate 41 is inserted to the end, and the pivot 43 is inserted into the J-shaped pivot support portion 30, and the tip of the engaging portion 20 by the protruding portion 25 is connected to the edge of the insertion plate 41. It stops in the form of overlapping with the engaged portion 40 by the recessed portion 42 formed in the portion 44.
 この状態でスライダー10を左右のファスナーストリンガー9を閉鎖する方向へ摺動させると、ファスナーエレメント6に当接していた案内柱11が抜け出し、左右のフランジ12によってファスナーエレメント6は噛合中心線へ押し出されて噛合する。同時に挿入板41も保持部21に向って進出して当接し、係合部20と被係合部40の重合度合が大きくなる。そしてスライダー10の摺動と同時に挿入板41が表裏のいずれかに揺動する動作を捉え、被係合部40は凹溝22のいずれかの係合部20と係合する。従って挿入板41はスライダー10の始動とは行動を共にせず安定した固定が行われ、差込体3を取り付けたファスナーストリンガー9を把持しなくとも微動だにしない。 In this state, when the slider 10 is slid in the direction in which the left and right fastener stringers 9 are closed, the guide pillar 11 that has been in contact with the fastener element 6 comes out, and the fastener element 6 is pushed out to the meshing center line by the left and right flanges 12. Mesh. At the same time, the insertion plate 41 advances toward and contacts the holding portion 21, and the degree of polymerization of the engaging portion 20 and the engaged portion 40 increases. At the same time as the slider 10 slides, the insertion plate 41 catches the movement of either the front or back, and the engaged portion 40 engages with the engaging portion 20 of the concave groove 22. Accordingly, the insertion plate 41 does not act at the same time as the start of the slider 10 and is stably fixed, and does not move finely even if the fastener stringer 9 to which the insert 3 is attached is not gripped.
 また係合部20と被係合部40を図7,8に示すように段差部34,50に形成して枢支体2と差込体3とを係合させてもよい。さらに図10,11に示すように係合部20と被係合部40とを凹溝22の底部24に突出する凸部29を設け、挿入板41の縁部44に切り欠いた凹部49を設け、凸部29と凹部49とを係合させても上記と同様の機能を呈す。 Further, the engaging portion 20 and the engaged portion 40 may be formed in step portions 34 and 50 as shown in FIGS.

 差込体3は、長方形の平板から挿入板41を形成され、噛合部17の脚部の下端すなわち芯紐7の表面に、細幅状に凹陥する凹窩部45を設けて区切り、ファスナーエレメント6の頭部側に縁部44を設ける。凹窩部45の延長線上の挿入板41にファスナーエレメント6と同厚の枢軸43を表裏に突設する。挿入板41の内側端縁にはスライダー10の表裏のフランジ12間の間隙よりも厚い突条部46を突設してスライダー10をガイドするとともに挿入板41を補強する。凹窩部45と突条部46の間はスライダー10のフランジ12を円滑に滑動できるように、滑動凹部47が形成されている。噛合部17は、枢支体2が取り付けられたファスナーストリンガー9の最下端のファスナーエレメント6と噛合する。 The insertion body 3 is formed with an insertion plate 41 from a rectangular flat plate, and is provided with a recess portion 45 that is recessed in a narrow width on the lower end of the leg portion of the meshing portion 17, that is, the surface of the core string 7. 6 is provided with an edge 44 on the head side. A pivot 43 having the same thickness as the fastener element 6 is provided on the front and back surfaces of the insertion plate 41 on the extension line of the recess 45. A protrusion 46 thicker than the gap between the front and back flanges 12 of the slider 10 is provided on the inner edge of the insertion plate 41 to guide the slider 10 and reinforce the insertion plate 41. A sliding recess 47 is formed between the recess 45 and the protrusion 46 so that the flange 12 of the slider 10 can slide smoothly. The meshing portion 17 meshes with the lowermost fastener element 6 of the fastener stringer 9 to which the pivotal support body 2 is attached.
 挿入板41の細幅状の縁部44の表面には、凹溝22の表裏内面に突設した突出部25による係合部20と係合する凹陥状の凹陥部42を設けて被係合部40を形成する。係合部20と被係合部40とは、図5に示すように、凹溝22の表裏内面に突設した突出部25の間隙は、挿入板41の厚みより小さく、凹陥部42の厚さより大きく形成することで、挿入板41が容易に係合できるように形成する。突出部25間の間隙を挿入板41の厚みと同等に形成することで、挿入板14がいずれか一方に揺動したとき、係合できるようにもできる。 The surface of the narrow edge portion 44 of the insertion plate 41 is provided with a recessed portion 42 having a recessed shape that engages with the engaging portion 20 by the protruding portion 25 protruding from the front and back inner surfaces of the recessed groove 22. Part 40 is formed. As shown in FIG. 5, the engagement portion 20 and the engaged portion 40 have a gap between the protruding portions 25 protruding from the front and back inner surfaces of the recessed groove 22 smaller than the thickness of the insertion plate 41 and the thickness of the recessed portion 42. By forming it larger than this, it is formed so that the insertion plate 41 can be easily engaged. By forming the gap between the protrusions 25 to be equal to the thickness of the insertion plate 41, it can be engaged when the insertion plate 14 swings to either one.
 この開き具1の使用態様については、前項で述べたとおりであり、図2に示すように枢支体2の枢支部30に当接して固定されたスライダー10に対し、肩口15から差込体3の挿入板41を差し込み、枢軸43が保持部21の外側縁部37によってガイドされエレメントガイド溝14に挿入し、図3に示すように、枢軸43はJ字状の枢支部30に嵌入して停止する。この際、突出部25による係合部20と凹陥部42による被係合部40は、凹溝22内で重合し、スライダー10の閉鎖方向への摺動によって、挿入板41が図4に示すようにA-A,B-B,C-Cと挿入板41が保持部21に対し進行するとともに、係合部20の突出部25と被係合部40の凹陥部42とが係合する度合が深まる。図4に示すC-Cの状態でファスナーエレメント6は互いに噛合し、スライドファスナーを閉鎖した状態となる。 The use mode of the opening tool 1 is as described in the previous section. As shown in FIG. 2, as shown in FIG. 2, the slider 10 fixed in contact with the pivotal support portion 30 of the pivotal support 2 is inserted from the shoulder opening 15. 3 is inserted, the pivot 43 is guided by the outer edge 37 of the holding portion 21 and inserted into the element guide groove 14, and the pivot 43 is fitted into the J-shaped pivot 30 as shown in FIG. And stop. At this time, the engaging portion 20 by the projecting portion 25 and the engaged portion 40 by the recessed portion 42 are overlapped in the concave groove 22, and the insertion plate 41 is shown in FIG. 4 by sliding the slider 10 in the closing direction. Thus, AA, BB, CC and the insertion plate 41 advance relative to the holding portion 21, and the protruding portion 25 of the engaging portion 20 and the recessed portion 42 of the engaged portion 40 engage with each other. The degree is deepened. In the CC state shown in FIG. 4, the fastener elements 6 are engaged with each other and the slide fastener is closed.
 図6に示す実施態様は、差込体3の挿入板41に設けた枢軸43を枢支部30に固定されたスライダー10の表裏のフランジ12間から挿入板41を挿入するとともに、枢軸43をJ字状の枢支部30の先端部分とスライダー10の後口16の間を通過して、最終的には枢軸43をJ字状の枢支部30に嵌入し、枢軸43を中心に回動して挿入板41を枢支体2の凹溝22内へ差し込んだ後、スライダー10を閉鎖方向へ摺動すると前記の機能と同一の機能を果す。また閉鎖され左右のファスナーストリンガー9を分離開放するには、スライダー10を枢支部30に向けて摺動し、スライダー10の肩口15から挿入板41を抜脱するか、または枢軸43を中心に回動してスライダー10の表裏のフランジ12間から挿入板41を抜き取り、同時に枢軸43を抜脱すれば、左右のファスナーストリンガー9を分離開放できる。 In the embodiment shown in FIG. 6, the pivot plate 43 provided on the insert plate 41 of the insertion body 3 is inserted between the front and back flanges 12 of the slider 10 fixed to the pivotal support portion 30, and Passing between the front end portion of the letter-shaped pivot 30 and the rear opening 16 of the slider 10, the pivot 43 is finally inserted into the J-shaped pivot 30 and rotated about the pivot 43. When the slider 10 is slid in the closing direction after the insertion plate 41 is inserted into the concave groove 22 of the pivotal support body 2, the same function as described above is achieved. In order to separate and open the left and right fastener stringers 9 closed, the slider 10 is slid toward the pivotal support 30 and the insertion plate 41 is removed from the shoulder opening 15 of the slider 10, or the pivot 43 is rotated around the pivot 43. The left and right fastener stringers 9 can be separated and opened by moving and extracting the insertion plate 41 from between the front and back flanges 12 of the slider 10 and simultaneously removing the pivot 43.
 図2に示すように、スライダー10の後口16を枢支部30に当接した状態で、突出部25は、スライダー10の後口16よりも内方(エレメントガイド溝内で肩口15側)に配置される。少なくとも突出部25の上面26がスライダー10の後口16よりも内方に配置されることが好ましい。このように配置することで、以下のような効果が期待できる。図2に示すように、差込板3をスライダー10の肩口15から差し込むと、枢軸43の下端側および外側の挿入板41の縁部44が、突出部25に接触することにより、挿入板41は凹溝22から抜け出る方向へ一旦移動させられるが、このとき突出部25の上面26がスライダー10の内方に配置されていることで、枢軸43がスライダー10から抜け出ることがなく、枢支体2の嵌入が確実に行える。 As shown in FIG. 2, in a state where the rear opening 16 of the slider 10 is in contact with the pivotal support portion 30, the protruding portion 25 is inward of the rear opening 16 of the slider 10 (on the shoulder opening 15 side in the element guide groove). Be placed. It is preferable that at least the upper surface 26 of the protrusion 25 is disposed inward of the rear opening 16 of the slider 10. By arranging in this way, the following effects can be expected. As shown in FIG. 2, when the insertion plate 3 is inserted from the shoulder opening 15 of the slider 10, the lower end side of the pivot 43 and the edge 44 of the outer insertion plate 41 come into contact with the protruding portion 25, thereby inserting the insertion plate 41. Is temporarily moved in the direction of exiting from the concave groove 22, but at this time, since the upper surface 26 of the projecting portion 25 is disposed inward of the slider 10, the pivot 43 does not escape from the slider 10, 2 can be securely inserted.
 図7~9に示す実施例2は、差込体3における挿入板41の縁部44の表面に形成する被係合部40は、枢軸42を突設した側を高くすなわち厚く形成し、ファスナーエレメント6側を低くすなわち薄く形成して段差部50を設け、段差部50よりファスナーエレメント6側を凹陥部42とし、枢支体2における凹溝22の表裏内面23に前記段差部50と係合することができる段差部34を設ける。この段差部34は枢支部30側の間隙を大きく形成し、ファスナーエレメント6側の間隙を小さく形成して、前記縁部44に形成した段差部50と合致する係合部20を設ける。 In the second embodiment shown in FIGS. 7 to 9, the engaged portion 40 formed on the surface of the edge portion 44 of the insertion plate 41 in the insertion body 3 is formed so that the side where the pivot 42 protrudes is formed high, that is, thick. The element 6 side is formed to be low or thin to provide a stepped portion 50, the fastener element 6 side from the stepped portion 50 is a recessed portion 42, and the stepped portion 50 is engaged with the front and back inner surfaces 23 of the recessed groove 22 in the pivot 2. A step 34 that can be provided is provided. The step 34 has a large gap on the side of the pivotal support 30 and a small gap on the side of the fastener element 6 to provide the engaging portion 20 that matches the step 50 formed on the edge 44.
 スライダー10を左右のファスナーストリンガー9を閉鎖する方向への摺動によって、段差部34, 50が係合し、挿入板41を不動の状態を作り出す。図9に示す場合を説明すると、挿入板41の形態は変らないが、保持部21の厚さ方向の凹溝22に形成する係合部20の形態が変って、段差部50と係合する係合部20は、中心へ向って突出する突出部25を形成して段差部34を設ける。この突出部25は上面26がファスナーエレメント6側に向うに従って、その間隙が広くなるように斜面38に形成して、挿入板41をスライダー10の肩口から挿入するとき円滑かつ容易に操作できる形態に形成する。 When the slider 10 is slid in the direction in which the left and right fastener stringers 9 are closed, the step portions 34 and the flanges 50 are engaged to create an immovable state of the insertion plate 41. 9, the shape of the insertion plate 41 does not change, but the shape of the engaging portion 20 formed in the concave groove 22 in the thickness direction of the holding portion 21 changes to engage the stepped portion 50. The engaging portion 20 forms a protruding portion 25 that protrudes toward the center and is provided with a stepped portion 34. The protrusion 25 is formed on the inclined surface 38 so that the gap becomes wider as the upper surface 26 faces toward the fastener element 6, and can be operated smoothly and easily when the insertion plate 41 is inserted from the shoulder of the slider 10. Form.
 前記実施例において、係合部20と被係合部40とが係合し、差込体3を備えるファスナーストリンガーがスライダー10と一緒に始動することを阻止するには、枢支体2の凹溝22の係合部20の上側(ファスナーエレメント6側)での厚さ方向の間隙が、下側(枢支部30側)の間隙よりも小さくなる段差状に形成し、差込体3の挿入板41の被係合部40の下側(枢軸43側)の厚みが、上側(ファスナーエレメント6側)の厚みよりも薄い段差を形成することで、それらが係合した状態で、スライダー10の始動と一緒に差込板3側のファスナーストリンガー9が上がることが阻止される。 In the above-described embodiment, the engagement portion 20 and the engaged portion 40 are engaged to prevent the fastener stringer including the insertion body 3 from starting together with the slider 10. The gap 22 in the thickness direction on the upper side (fastener element 6 side) of the engagement portion 20 of the groove 22 is formed in a step shape that becomes smaller than the gap on the lower side (pivot support portion 30 side). By forming a step in which the thickness of the lower side (the pivot 43 side) of the engaged portion 40 of the plate 41 is thinner than the thickness of the upper side (fastener element 6 side), the slider 10 The fastener stringer 9 on the insertion plate 3 side is prevented from rising together with the start.
 上記実施例1、実施例2において、凹溝22内に突出して形成する係合部20である突出部25および段差部34は、凹溝22を形成する保持部21の表裏両側の内面23に形成しているが、どちらか一方に形成するのみであってもよく、この場合には、前記係合部20と係合する被係合部40である凹陥部42および段差部50も表裏の一方側のみに形成される。 In the first embodiment and the second embodiment, the protruding portion 25 and the stepped portion 34 which are the engaging portions 20 protrudingly formed in the concave groove 22 are formed on the inner surfaces 23 on both sides of the holding portion 21 forming the concave groove 22. However, in this case, the recessed portion 42 and the stepped portion 50 that are engaged portions 40 that engage with the engaging portion 20 are also formed on the front and back sides. It is formed only on one side.
 図10,11に示す実施例3は、係合部20と被係合部40の形態が前記実施例とは異なる。すなわち前記実施例では、係合部20と被係合部40は、枢支体2と差込体3の表裏両面に形成したが、この実施例では、係合部20と被係合部40は側面、すなわち保持部21における凹溝22の底部24と、挿入板41の縁部44の側端48に形成する。枢支体2と差込体3が側面で当接する衝合面に設ける。 Example 3 shown in FIGS. 10 and 11 is different from the above example in the form of the engaging portion 20 and the engaged portion 40. That is, in the said Example, although the engaging part 20 and the to-be-engaged part 40 were formed in the front and back both surfaces of the pivot 2 and the insertion body 3, in this Example, the engaging part 20 and the to-be-engaged part 40 were formed. Is formed on the side surface, that is, the bottom 24 of the groove 22 in the holding portion 21 and the side edge 48 of the edge 44 of the insertion plate 41. The pivoting body 2 and the insertion body 3 are provided on the abutting surface where the side surfaces abut.
 枢支体2の保持部21における凹溝22の底部24において、枢支部30に近い部位に円弧状に突出する凸部29を設けて係合部20を形成する。凸部29は必ずしも円弧状でなくとも突出する適宜形状であってもよい。この係合部20と対面する挿入板41における縁部44の側端48に円弧状に切り欠いた凹部49を設けて、被係合部40を形成する。 In the bottom part 24 of the concave groove 22 in the holding part 21 of the pivotal support body 2, a convex part 29 protruding in an arc shape is provided at a part near the pivotal support part 30 to form the engaging part 20. The convex part 29 does not necessarily have an arc shape but may have an appropriate shape that protrudes. A recessed portion 49 cut out in an arc shape is provided at a side end 48 of the edge portion 44 of the insertion plate 41 facing the engaging portion 20 to form the engaged portion 40.
 凸部29と凹部49の位置関係を説明すると、保持部21における凹溝22の底部24に形成する凸部29は、保持部21の外側縁部37との間隔をLとしたとき、挿入板41における縁部44と枢軸43との間隔をlとすると、L>lの関係が存在すれば、挿入板41をスライダー10の肩口15から挿入しても、枢軸43は凸部29に当接して支障をきたすことがない。 The positional relationship between the convex portion 29 and the concave portion 49 will be described. The convex portion 29 formed on the bottom portion 24 of the concave groove 22 in the holding portion 21 has an insertion plate when the distance from the outer edge 37 of the holding portion 21 is L. Assuming that the distance between the edge 44 and the pivot 43 at 41 is l, the pivot 43 abuts against the convex 29 even if the insertion plate 41 is inserted from the shoulder opening 15 of the slider 10 if a relationship of L> l exists. Will not cause any trouble.
 使用態様を説明すれば、スライダー10を枢支部30に当接して固定した後、スライダー10の肩口15から、差込体3の挿入板41を枢軸43側から挿入し、枢支体2の保持部21の外側縁部37によって、枢軸43をガイドしてJ字状の枢支部30に枢軸43を嵌入する。この状態からスライダー10を左右のファスナーストリンガー9を閉鎖する方向へ僅かに始動すると、スライダー10の案内柱11が枢支体2と差込体3を抜けると、スライダー10の両側のフランジ12によって、挿入板41を凹溝22の底部24に対し、押し付けるため、凸部29と凹部49とが素早く嵌合し、確実に係合する。従って両手が使えず片手でスライダー10を操作しても、スライダー10と一緒に差込体3を備えたファスナーストリンガー9が始動することがない。また閉鎖された左右のファスナーストリンガー9を分離開放するには、スライダー10を枢支部30に向けて摺動し、スライダー10の肩口15から挿入板41を抜脱するか、または枢軸43を中心に回動して、スライダーの表裏のフランジ12間から挿入板41を抜き取り、同時に枢軸43を抜脱すれば左右のファスナーストリンガー9を分離開放できる。 Explaining how to use, after the slider 10 is fixed in contact with the pivot 30, the insertion plate 41 of the insertion body 3 is inserted from the side of the pivot 43 through the shoulder 15 of the slider 10 to hold the pivot 2. The pivot 43 is guided by the outer edge 37 of the portion 21 and is inserted into the J-shaped pivot 30. From this state, when the slider 10 is slightly started in the direction of closing the left and right fastener stringers 9, when the guide pillar 11 of the slider 10 passes through the pivot body 2 and the insertion body 3, the flanges 12 on both sides of the slider 10 In order to press the insertion plate 41 against the bottom 24 of the concave groove 22, the convex portion 29 and the concave portion 49 are quickly fitted and reliably engaged. Therefore, even if the slider 10 is operated with one hand without using both hands, the fastener stringer 9 provided with the insertion body 3 together with the slider 10 does not start. In order to separate and open the left and right fastener stringers 9 which are closed, the slider 10 is slid toward the pivotal support 30 and the insertion plate 41 is removed from the shoulder opening 15 of the slider 10 or the pivot 43 is centered. The left and right fastener stringers 9 can be separated and opened by rotating and extracting the insertion plate 41 from between the front and back flanges 12 of the slider and simultaneously removing the pivot 43.
 図11に示す使用態様は、差込体3の挿入板41に設けた枢軸43を枢支部30に固定されたスライダー10の表裏のフランジ12間から挿入板41を挿入するとともに、枢軸43をJ字状の枢支部30の先端部分とスライダー10の後口16の間を通過して、最終的に枢軸43をJ字状の枢支部30に嵌入し、枢軸43を中心に回動して挿入板41を枢支体2に押し付けた後、スライダー10を閉鎖方向へ摺動すると前記の機能と同一の機能を果す。また閉鎖された左右のファスナーストリンガー9を分離開放するには、スライダー10を枢支部30に向けて摺動し、スライダー10の肩口15から挿入板41を抜脱するか、または枢軸43を中心に回動してスライダー10の表裏のフランジ12間から挿入板41を抜き取り、同時に枢軸43を抜脱すれば、左右のファスナーストリンガー9を分離開放できる。 11, the insertion plate 41 is inserted from between the flanges 12 on the front and back of the slider 10 fixed to the pivotal support 30 with the pivot 43 provided on the insertion plate 41 of the insertion body 3 being used. Passing between the tip of the letter-shaped pivot 30 and the rear opening 16 of the slider 10, the pivot 43 is finally fitted into the J-shaped pivot 30 and rotated around the pivot 43 for insertion. If the slider 41 is slid in the closing direction after the plate 41 is pressed against the pivot 2, the same function as described above is achieved. In order to separate and open the left and right fastener stringers 9 which are closed, the slider 10 is slid toward the pivotal support 30 and the insertion plate 41 is removed from the shoulder opening 15 of the slider 10 or the pivot 43 is centered. By rotating and extracting the insertion plate 41 between the front and back flanges 12 of the slider 10 and simultaneously removing the pivot 43, the left and right fastener stringers 9 can be separated and opened.
 図12に示す実施例4は、開き具1の裏側に枢軸43の掛止機構を枢支体2に配設した開き具1であり、その特徴とする構成は、掛止機構にある。この掛止機構は、枢支体2におけるJ字状の枢支部30に、挿入板41の表裏へ突出する枢軸43を嵌入する部分の上方に、枢支部30の内側へ突出する小突起52を設け、この小突起52を配した枢支部30の内側に縁部に沿って空間条部53を穿設して、縁部が容易に弾性変形ができるように弾性片54を形成して、嵌入相手の枢軸43が掛止できる形態に形成する。前記小突起52は、J字状の枢支部30の先端との間隔を枢軸43の直径より小さくなるようにする。 Example 4 shown in FIG. 12 is the opening tool 1 in which the locking mechanism of the pivot 43 is disposed on the pivotal support body 2 on the back side of the opening tool 1, and the characteristic configuration thereof is in the locking mechanism. This latching mechanism has a small protrusion 52 that protrudes to the inside of the pivot 30 above the portion into which the pivot 43 that projects to the front and back of the insertion plate 41 is fitted to the J-shaped pivot 30 of the pivot 2. A space strip 53 is drilled along the edge on the inside of the pivotal support 30 provided with the small protrusion 52, and an elastic piece 54 is formed so that the edge can be easily elastically deformed. It forms so that the other party's pivot 43 can be hooked. The small protrusion 52 makes the distance from the tip of the J-shaped pivot 30 smaller than the diameter of the pivot 43.
 この実施例においては、一旦、枢軸43を枢支部30に嵌入すると、枢軸43が弾性片54を変形させて、小突起52を越えた時点で弾性片54が復帰すると、その上方に設けた小突起52により、枢軸43が枢支部30から脱出するのが困難であり、スライダー10を左右のファスナーストリンガー9を閉鎖する方向への摺動に対しては、挿入板41を備えたファスナーストリンガー9が、スライダー10と一緒に摺動するのを小突起52の設置により、枢支部30が枢軸43を掛止するので、枢軸43の脱出を未然に防ぐ、また弾性片54を設けることにより、枢軸43を枢支部30から脱却させる操作が容易である。 In this embodiment, once the pivot 43 is fitted into the pivotal support 30, the pivot 43 deforms the elastic piece 54, and when the elastic piece 54 returns when it exceeds the small protrusion 52, the small piece provided above the pivot piece 43. The projection 52 makes it difficult for the pivot 43 to escape from the pivot 30 and the fastener stringer 9 having the insertion plate 41 is used for sliding the slider 10 in the direction of closing the left and right fastener stringers 9. By sliding the slider 10 together with the small protrusion 52, the pivotal portion 30 engages the pivot 43, so that the pivot 43 is prevented from escaping, and by providing the elastic piece 54, the pivot 43 Is easy to escape from the pivot 30.
