（第１の実施の形態）
　図１は、本発明の第１の実施の形態に係るスライドファスナー開具１０を備えたファスナーチェーン２上にスライダー８を取り付けて得られるスライドファスナー１の正面図である。ファスナーチェーン２は、一対のファスナーテープ４の対向する側縁部４１に沿って列設された複数のエレメント５を含むエレメント列６を備える一対のファスナーストリンガー３と、エレメント列６の一方の端部に配置された止具７と、エレメント列６の他方の端部に配置されたスライドファスナー開具１０とを備える。 (First embodiment)
FIG. 1 is a front view of a slide fastener 1 obtained by attaching a slider 8 on a fastener chain 2 provided with a slide fastener opener 10 according to a first embodiment of the present invention. The fastener chain 2 includes a pair of fastener stringers 3 including an element row 6 including a plurality of elements 5 arranged along opposing side edge portions 41 of the pair of fastener tapes 4, and one end portion of the element row 6. And a slide fastener opening device 10 disposed at the other end of the element row 6.
　図７に示すように、複数のエレメント５はそれぞれ平面視がファスナーテープ４の長手方向に長円形状を有する噛合頭部５１と、噛合頭部５１からファスナーテープ４の幅方向へ延びる首部５２と、首部５２から更にファスナーテープ４の幅方向へと延びる基部５３とを備えている。向かい合うエレメント５の噛合頭部５１と首部５２とがファスナーテープ４の側縁部４１上でスライダー８を用いて噛合又は噛合解除させることにより、スライドファスナー１の開閉が行われる。 As shown in FIG. 7, each of the plurality of elements 5 includes a meshing head 51 having an oval shape in the longitudinal direction of the fastener tape 4 in plan view, and a neck 52 extending from the meshing head 51 in the width direction of the fastener tape 4. The base 53 further extends from the neck 52 in the width direction of the fastener tape 4. The slide fastener 1 is opened and closed by engaging or releasing the engagement between the meshing head 51 and the neck 52 of the element 5 facing each other on the side edge 41 of the fastener tape 4 using the slider 8.
　スライドファスナー開具１０は、図２に示すように、一方のファスナーテープ４（図２の紙面左側のファスナーテープ４）のエレメント列６の端部に配置された蝶棒１１と、他方のファスナーテープ４（図２の紙面右側のファスナーテープ４）のエレメント列６の端部において双方のファスナーテープ４を跨ぐように延設され、蝶棒１１を内部に収容可能な箱体１２と、他方のファスナーテープ４上において蝶棒１１と対向し、エレメント列６と箱体１２との間に配置され、箱体１２との間に第１の隙間１４を形成するように箱体１２から離間して配置された箱棒１３とを備える。 As shown in FIG. 2, the slide fastener opening 10 includes a butterfly bar 11 disposed at the end of the element row 6 of one fastener tape 4 (the fastener tape 4 on the left side of FIG. 2), and the other fastener tape 4. A box 12 that extends over both the fastener tapes 4 at the end of the element row 6 of the fastener tape 4 on the right side of the paper (FIG. 2) and can accommodate the butterfly bar 11 inside, and the other fastener tape 4 is opposed to the butterfly pin 11, is disposed between the element row 6 and the box 12, and is spaced apart from the box 12 so as to form a first gap 14 between the box 12. A box bar 13 is provided.
　蝶棒１１は、第２の隙間１５を介して少なくとも２つに分割されていることが好ましい。図２においては、第２の隙間１５を介して蝶棒１１を２つの蝶棒１１ａ、１１ｂに分割した例が示されている。蝶棒１１は、一般的には、エレメント５、止具７等の部品に比べて細長い形状を有する部品であり、ファスナーテープ４の端部に配置されるため、強度が強い原材料を用いて製造しないと、手でつまんだ場合に折れたり、長年の使用又は外部との接触により破損が生じたりする場合がある。第１の実施の形態に係るスライドファスナー開具１０によれば、蝶棒１１が複数の小さな部品に分割されているため、従来の細長い蝶棒と比べて外力に強く、原材料として比較的強度の弱い材料を用いて蝶棒１１を製造した場合であっても破損や変形が生じにくくなる。 The butterfly stick 11 is preferably divided into at least two through the second gap 15. In FIG. 2, the example which divided | segmented the butterfly stick 11 into the two butterfly sticks 11a and 11b through the 2nd clearance gap 15 is shown. The butterfly stick 11 is generally a part having an elongated shape compared to the parts such as the element 5 and the stopper 7, and is disposed at the end of the fastener tape 4. Otherwise, it may break when pinched by hand, or it may be damaged due to long-term use or contact with the outside. According to the slide fastener opening device 10 according to the first embodiment, since the butterfly pin 11 is divided into a plurality of small parts, it is more resistant to external force than a conventional elongated butterfly pin and relatively weak as a raw material. Even when the butterfly stick 11 is manufactured using a material, breakage and deformation are less likely to occur.
　ここで、第２の隙間１５は、図１に示すように、蝶棒１１を箱体１２内に収容したときに箱体１２の外部に露出されるように、箱体１２から露出した蝶棒１１の一部上に配置されることが好ましい。これにより、ファスナーテープ４の撓み等によって箱体１２付近に外力が加わる場合も、箱体１２付近に設けられた第１の隙間１４及び第２の隙間１５においてファスナーテープ４が曲がることでその外力が蝶棒１１や箱棒１３に伝わりにくくなるため、蝶棒１１や箱棒１３の破損又は変形が抑制される。 Here, as shown in FIG. 1, the second gap 15 is a butterfly stick exposed from the box body 12 so as to be exposed to the outside of the box body 12 when the butterfly stick 11 is accommodated in the box body 12. 11 is preferably disposed on a part of 11. Thereby, even when an external force is applied near the box 12 due to the bending of the fastener tape 4 or the like, the external force of the fastener tape 4 is bent in the first gap 14 and the second gap 15 provided near the box 12. Is difficult to be transmitted to the butterfly stick 11 and the box stick 13, so that the damage or deformation of the butterfly stick 11 and the box stick 13 is suppressed.
　第１の隙間１４及び第２の隙間１５の大きさには、特に制限はない。しかしながら、隙間が大きすぎると、蝶棒１１ａ及び箱棒１３と隣接するエレメント５の噛合が外れたり異物が挟まったりするおそれがある。隙間が小さすぎると、蝶棒１１及び箱棒１３の破損抑制の効果が小さい。そのため、隙間の大きさは、ファスナーテープ４の長手方向に配置されたエレメント５とエレメント５との間隔程度とするのが好ましい。エレメント５の大きさとそれに応じたスライドファスナー開具１０の大きさによって、第１の隙間１４及び第２の隙間１５をそれぞれ任意に設定することができる。 The size of the first gap 14 and the second gap 15 is not particularly limited. However, if the gap is too large, the element 5 adjacent to the butterfly stick 11a and the box stick 13 may be disengaged or foreign matter may be caught. If the gap is too small, the effect of suppressing breakage of the butterfly stick 11 and the box stick 13 is small. Therefore, it is preferable that the size of the gap is about the interval between the element 5 and the element 5 arranged in the longitudinal direction of the fastener tape 4. The first gap 14 and the second gap 15 can be arbitrarily set according to the size of the element 5 and the size of the slide fastener opening tool 10 corresponding thereto.
　図２に示すように、箱体１２は、ファスナーテープ４の長手方向の終端において、ファスナーテープ４の幅方向（図２の紙面左右方向）に延設されている。図３に示すように、箱体１２は、蝶棒１１と対向する蝶棒対向面１２１上に、ファスナーテープ４の長手方向に沿ってスリット１２２が刻まれている。このスリット１２２の奥には、図４に示すように蝶棒１１ｂを収容するための空洞を有する空洞部１２４が形成されている。蝶棒１１ｂはこの空洞部１２４内に収容される。図２に示すように、箱棒１３は更に、ファスナーテープ４の長手方向の終端において、ファスナーテープ４の幅方向に延在する箱体補強部１２３を備えている。箱体補強部１２３は箱体１２と一体成形により形成されている。この箱体補強部１２３により、ファスナーテープ４の終端の強度向上が図れる。同様の目的で、箱棒１３と対向する蝶棒１１ｂにも、ファスナーテープ４の幅方向に延在する蝶棒補強部１１３が、蝶棒１１ｂと一体成形により形成されている。 As shown in FIG. 2, the box 12 extends in the width direction of the fastener tape 4 (left and right direction in FIG. 2) at the longitudinal end of the fastener tape 4. As shown in FIG. 3, the box 12 has a slit 122 cut along the longitudinal direction of the fastener tape 4 on the butterfly pin facing surface 121 facing the butterfly pin 11. A cavity 124 having a cavity for accommodating the butterfly stick 11b is formed in the back of the slit 122 as shown in FIG. The butterfly stick 11b is accommodated in the cavity 124. As shown in FIG. 2, the box bar 13 further includes a box reinforcing portion 123 extending in the width direction of the fastener tape 4 at the end of the fastener tape 4 in the longitudinal direction. The box reinforcing part 123 is formed by integral molding with the box 12. The box reinforcing portion 123 can improve the strength of the end of the fastener tape 4. For the same purpose, a butterfly bar reinforcing portion 113 extending in the width direction of the fastener tape 4 is also formed on the butterfly bar 11b facing the box bar 13 by integral molding with the butterfly bar 11b.
　箱棒１３は、箱体１２との間に第１の隙間１４を有して配置されている。箱棒１３は、一般的には、箱体１２と連結されていることが多い。そのため、開具１０付近のファスナーテープ４が撓んだ場合には、箱体１２と箱棒１３との連結部分で割れや亀裂が発生する場合がある。第１の実施の形態では、第１の隙間１４が形成されているため、開具１０付近のファスナーテープ４が撓んだ場合でも、箱棒１３に不要な力がかからなくなるため、箱棒１３の破損又は変形が抑制される。 The box bar 13 is arranged with a first gap 14 between the box body 13 and the box body 12. In many cases, the box bar 13 is generally connected to the box body 12. Therefore, when the fastener tape 4 in the vicinity of the opening tool 10 is bent, a crack or a crack may occur at the connecting portion between the box 12 and the box bar 13. In the first embodiment, since the first gap 14 is formed, unnecessary force is not applied to the box bar 13 even when the fastener tape 4 near the opening 10 is bent. Is prevented from being damaged or deformed.
　箱棒１３は、図３に示すように、蝶棒１１と対向する蝶棒対向面１３１から蝶棒１１側に向けて突出する係止凸部１３２を備える。図２に示すように、係止凸部１３２は、ファスナーテープ４の長手方向に沿って配置されており、蝶棒対向面１３１の箱棒１３側からエレメント列６側に向けて徐々に蝶棒１１側へ突出するように配置されている。この係止凸部１３２を収容するために、蝶棒１１ａの箱棒１３と対向する箱棒対向面１１１には、溝状の収容凹部１１２が刻まれている。収容凹部１１２は、ファスナーテープ４の長手方向に沿って蝶棒１１ａの箱棒対向面１１１全体に延びて配置されている。 As shown in FIG. 3, the box bar 13 includes a locking projection 132 that protrudes toward the butterfly stick 11 side from the butterfly stick facing surface 131 that faces the butterfly stick 11. As shown in FIG. 2, the locking projection 132 is disposed along the longitudinal direction of the fastener tape 4 and gradually moves from the box bar 13 side of the butterfly bar facing surface 131 toward the element row 6 side. It is arrange | positioned so that it may protrude to 11 side. In order to accommodate the locking projection 132, a groove-shaped accommodation recess 112 is formed on the box bar facing surface 111 of the butterfly bar 11a facing the box bar 13. The housing recess 112 extends along the longitudinal direction of the fastener tape 4 and extends over the entire box bar facing surface 111 of the butterfly bar 11a.
　箱棒１３と対向する蝶棒１１ａには、蝶棒１１ａの表面１１５及び裏面１１６からそれぞれ箱棒１３側に突出し、対向するファスナーテープ４のエレメント列６の最端部にあるエレメント５ａ（図２参照）の首部５２と噛み合う突片部１１７と、蝶棒１１ａの表面１１５及び裏面１１６に設けられ、突片部１１７と隣接する凹みであって最端部にあるエレメント５ａの噛合頭部５１を収容する切り欠き部１１８とを備える。突片部１１７及び切り欠き部１１８がエレメント５ａの噛合頭部５１及び首部５２と噛み合うことにより、ファスナーテープ４を幅方向へ引っ張る力が働いても、エレメント５同士の噛合が外れにくくなる。また、ファスナーテープ４の表裏方向から突き上げるような力が加わった場合でも、板状の係止凸部１３２が収容凹部１１２内に収容された状態で突片部１１７及び切り欠き部１１８がエレメント５ａの噛合頭部５１及び首部５２と噛み合っているため、エレメント５同士の噛合が外れにくくなる。 The butterfly bar 11a facing the box bar 13 protrudes from the front surface 115 and the back surface 116 of the butterfly bar 11a toward the box bar 13 and is located at the end of the element row 6 of the opposed fastener tape 4 (see FIG. 2). (See FIG. 5), the projecting portion 117 meshing with the neck portion 52, and the engaging head 51 of the element 5a provided on the front surface 115 and the back surface 116 of the butterfly pin 11a and in the recess adjacent to the projecting portion 117 and at the extreme end. And a notch 118 to be accommodated. The protrusions 117 and the cutouts 118 mesh with the meshing head 51 and the neck 52 of the element 5a, so that even if a force pulling the fastener tape 4 in the width direction is applied, the elements 5 are not easily engaged with each other. Further, even when a force that pushes up from the front and back direction of the fastener tape 4 is applied, the protruding piece portion 117 and the notch portion 118 are formed in the element 5a in a state where the plate-like locking projection 132 is accommodated in the accommodation recess 112. Since the meshing head 51 and the neck 52 are meshed with each other, the meshing between the elements 5 is difficult to come off.
　このように、第１の実施の形態に係るスライドファスナー開具１０によれば、箱体１２と箱棒１３とが第１の隙間１４を介して配置され、蝶棒１１が第２の隙間１５を介して蝶棒１１ａ、蝶棒１１ｂに分割される。これにより、ファスナーテープ４が外力により撓んだり変形したりした場合でも、蝶棒１１、箱体１２、及び箱棒１３にそれぞれ余計な力が加わらなくなる。その結果、スライドファスナー開具１０の材料として、比較的強度の弱い材料を用いた場合でも開具１０の破損が生じにくくなり、スライドファスナー開具１０の材料として様々な種類の樹脂を使用できるようになるため、生産性が向上する。スライドファスナー開具１０の材料として環境を考慮した材料を使用すれば、スライドファスナー１として使用した後の廃棄処理も容易になる。例えば、スライドファスナー開具１０に用いられる材料としては、例えば従来のポリアセタール等の樹脂、鉄、銅合金、亜鉛合金、アルミニウム合金、ステンレス等の金属の他に、ポリアミド、ポリプロピレン、ポリブチレンテレフタレート、ポリカーボネート等の熱可塑性合成樹脂も好適に用いることができる。 As described above, according to the slide fastener opening device 10 according to the first embodiment, the box 12 and the box bar 13 are arranged through the first gap 14, and the butterfly bar 11 has the second gap 15. It is divided into a butterfly stick 11a and a butterfly stick 11b. Thereby, even when the fastener tape 4 is bent or deformed by an external force, an extra force is not applied to the butterfly stick 11, the box body 12, and the box stick 13, respectively. As a result, even when a relatively weak material is used as the material for the slide fastener opener 10, the opener 10 is less likely to be damaged, and various types of resins can be used as the material for the slide fastener opener 10. , Improve productivity. If a material in consideration of the environment is used as the material of the slide fastener opening device 10, the disposal process after the use as the slide fastener 1 is facilitated. For example, examples of the material used for the slide fastener opening 10 include polyamide, polypropylene, polybutylene terephthalate, polycarbonate, etc., in addition to conventional resins such as polyacetal, metals such as iron, copper alloy, zinc alloy, aluminum alloy, and stainless steel. These thermoplastic synthetic resins can also be suitably used.
　更に、第１の実施の形態に係るスライドファスナー開具１０及びこれを用いたファスナーチェーン２及びスライドファスナー１によれば、箱体１２の周辺に、第１の隙間１４及び第２の隙間１５が形成される。第１の隙間１４及び第２の隙間１５は、スライダー８を摺動させてエレメント５同士を噛合させる際に、誤って砂、泥、糸くず又はホコリなどの異物が挟まった場合に、異物を排出させるための空間としても機能させることができる。 Furthermore, according to the slide fastener opening device 10 according to the first embodiment and the fastener chain 2 and the slide fastener 1 using the same, the first gap 14 and the second gap 15 are formed around the box 12. Is done. The first gap 14 and the second gap 15 are used to prevent foreign matter such as sand, mud, lint, or dust from being caught when the slider 8 is slid and the elements 5 are engaged with each other. It can also function as a space for discharging.
　次に、第１の実施の形態に係るスライドファスナー開具１０を備えるスライドファスナー１を用いて、一対のエレメント列６を噛合させるときの操作について、図４～図６を用いて説明する。まず、図４に示すように、スライダー８をエレメント列６に沿ってスライドさせて箱体１２のエレメント列６側の端面１２７と当接させる。これにより、ファスナーテープ４の箱棒１３、最端部のエレメント５ａはスライダー８の側面にあるフランジ８１に係止された状態でスライダー８内に収容される。この状態で、ファスナーテープ４上に取り付けられた蝶棒１１を、スライダー８の側面のフランジ８２に形成されたファスナーテープ４を挿入するための溝（図示せず）に沿ってスライダー８の内部へ収容させる。 Next, an operation when the pair of element rows 6 are engaged with each other using the slide fastener 1 including the slide fastener opening device 10 according to the first embodiment will be described with reference to FIGS. First, as shown in FIG. 4, the slider 8 is slid along the element row 6 and brought into contact with the end surface 127 of the box 12 on the element row 6 side. As a result, the box bar 13 of the fastener tape 4 and the element 5 a at the extreme end are accommodated in the slider 8 while being locked to the flange 81 on the side surface of the slider 8. In this state, the butterfly stick 11 attached on the fastener tape 4 is moved into the slider 8 along a groove (not shown) for inserting the fastener tape 4 formed on the flange 82 on the side surface of the slider 8. Contain.
　図５に示すように、蝶棒１１ｂは、フランジ８２に案内されながら箱棒１３に形成されている係止凸部１３２を通過し、図６に示すように、箱体１２の空洞部１２４内に収容されて箱体１２内で停止する。このとき、図６に示すように、蝶棒１１ａに形成された収容凹部１１２が箱棒１３の係止凸部１３２と対向し、係止凸部１３２が収容凹部１１２内に収容される。その後、スライダー８をエレメント列６方向へスライドさせると、蝶棒１１ｂの突片部１１７がエレメント列６の最端部にあるエレメント５ａの首部５２の凹みに収容される。これと同時に、エレメント列６の最端部にあるエレメント５ａの噛合頭部５１が、蝶棒１１ｂの切り欠き部１１８内に収容される。これにより、図１に示すように、蝶棒１１ｂと最端部にあるエレメント５ａの噛合頭部５１及び首部５２とが噛合される。その後、スライダー８をエレメント列６の止具７の方向にそのままスライドさせることにより、エレメント５同士の噛合が行われる。 As shown in FIG. 5, the butterfly stick 11 b passes through the locking projection 132 formed on the box bar 13 while being guided by the flange 82, and inside the cavity 124 of the box 12 as shown in FIG. 6. And is stopped in the box 12. At this time, as shown in FIG. 6, the housing recess 112 formed in the butterfly stick 11 a faces the locking projection 132 of the box bar 13, and the locking projection 132 is received in the storage recess 112. Thereafter, when the slider 8 is slid in the element row 6 direction, the projecting piece 117 of the butterfly pin 11 b is accommodated in the recess of the neck portion 52 of the element 5 a at the end of the element row 6. At the same time, the meshing head 51 of the element 5a at the extreme end of the element row 6 is accommodated in the notch 118 of the butterfly pin 11b. As a result, as shown in FIG. 1, the butterfly pin 11b and the meshing head 51 and neck 52 of the element 5a at the extreme end are meshed.

The reinforcing layer 42 made of polyamide is formed of a film-like thin film and a thin layer.
（第４の実施の形態）
　第４の実施の形態に係るスライドファスナー１は、図１２～図１４に示すように、スライドファスナー開具１０を構成する蝶棒１１、箱体１２及び箱棒１３と、開具１０と隣接するエレメント５がそれぞれ金属製で形成されている点が、図１に示すスライドファスナー１と異なる。蝶棒１１は、図１３に示すように、第２の隙間１５を介して柱状の蝶棒１１ａと蝶棒１１ｂとに分割されている。箱体１２は、蝶棒１１と対向する蝶棒対向面１２１にスリット１２２を有し、内部にはスリット１２２と通じる空洞を有する空洞部１２４が形成されている。図１４に示すように、エレメント５同士が噛合してスライドファスナー１が閉じられる際には、空洞部１２４内に蝶棒１１ｂが収容される。箱棒１３は薄板状であり、箱体１２から第１の隙間１４を有して離間して配置されている。開具１０とエレメント５を構成する金属としては、亜鉛合金、銅合金、丹銅、アルミニウム合金等が使用可能である。このように、第４の実施の形態に示すスライドファスナー１においても、蝶棒１１が少なくとも２つ以上に分割されるとともに、箱棒１３が箱体１２から第１の隙間１４を介して離間しているため、蝶棒１１及び箱棒１３が箱体１２と連結される構成の従来の開具と比べて、蝶棒１１又は箱棒１３に加わる外力を小さくできる。 (Fourth embodiment)
As shown in FIGS. 12 to 14, the slide fastener 1 according to the fourth embodiment includes a butterfly stick 11, a box body 12 and a box stick 13 constituting the slide fastener opening tool 10, and an element 5 adjacent to the opening tool 10. Are different from the slide fastener 1 shown in FIG. As shown in FIG. 13, the butterfly stick 11 is divided into a columnar butterfly stick 11 a and a butterfly stick 11 b through a second gap 15. The box 12 has a slit 122 on a butterfly pin facing surface 121 facing the butterfly pin 11, and a cavity portion 124 having a cavity communicating with the slit 122 is formed inside. As shown in FIG. 14, when the elements 5 are engaged with each other and the slide fastener 1 is closed, the butterfly pin 11 b is accommodated in the cavity portion 124. The box bar 13 is in the form of a thin plate and is spaced apart from the box 12 with a first gap 14. As a metal constituting the opening tool 10 and the element 5, zinc alloy, copper alloy, red copper, aluminum alloy, or the like can be used. Thus, also in the slide fastener 1 shown in the fourth embodiment, the butterfly stick 11 is divided into at least two or more and the box stick 13 is separated from the box 12 via the first gap 14. Therefore, the external force applied to the butterfly stick 11 or the box stick 13 can be reduced as compared with the conventional opener configured to connect the butterfly stick 11 and the box stick 13 to the box body 12.
（その他の実施の形態）
　上記のように本発明の実施の形態を記載したが、この開示の一部をなす論述及び図面は、この発明を限定するものであると理解すべきではない。 (Other embodiments)
