Description

【０００１】
【発明の属する技術分野】
この発明に係る引戸障子の外れ止め装置は、一般家屋やビルディング等の建造物の窓開口を開閉する為の窓装置に組み込んで、閉鎖状態に移動させた引戸障子を窓枠の内側から取り外せない様にする為のものである。
【０００２】
【従来の技術】
各種建造物の窓開口を開閉する為の窓装置として、窓枠内に建て込んだ引戸障子を水平移動させる引戸式窓装置が、広く使用されている。この様な引戸式窓装置の場合、防犯、或は安全確保の為、引戸障子を閉鎖状態に移動させた場合に浮き上がる事を防止して、閉鎖状態にある引戸障子が上記窓枠から外れない様にしている。この為に従来から、上記窓枠を構成する上枠の下面に外れ止め片を装着し、上記引戸障子を閉鎖状態に移動させた場合には、この外れ止め片の下面を上記引戸障子の上縁に近接対向させる様にしている。そして、上記引戸障子の下框に組み付けた戸車と上記窓枠を構成する下枠の上面に設けた下部案内レールとの係合が外れる程、上記引戸障子が浮き上がるのを防止している。
【０００３】
この様な引戸障子の外れ止め装置として従来から、実開昭５４−５３３７号公報、実公昭５５−５６４７号公報等に記載されたものが知られている。このうちの実開昭５４−５３３７号公報に記載された構造は、上枠の下面に係止したブロックに設けたねじ孔に下方から調節ねじの下端部に固定した当接片を、引戸障子の上縁に近接対向自在としている。又、実公昭５５−５６４７号公報に記載された構造は、上枠の下面にねじ止め固定した外れ止めブロックを、引戸障子の上縁に近接対向自在としている。
【０００４】
【発明が解決しようとする課題】
従来構造の場合、実際に外れ止め装置が機能する様にする為には、調節ねじを何回転もさせて、上枠の下面から当接片を十分に離したり（実開昭５４−５３３７号公報に記載された構造の場合）、外れ止めブロックを上枠にねじ止め固定する作業が必要になる（実公昭５５−５６４７号公報に記載された構造の場合）等、作業が面倒である。
本発明は、この様な事情に鑑みて、実際に機能する様にする為に要する作業を簡略にできる引戸障子の外れ止め装置を実現すべく、発明したものである。
【０００５】
【課題を解決するための手段】
本発明の引戸障子の外れ止め装置は、従来から知られている引戸障子の外れ止め装置と同様に、窓枠内に水平移動自在に建て込まれた引戸障子の下框に組み付けた戸車とこの窓枠を構成する下枠の上面に設けた下部案内レールとの係合が外れるのを防止すべく、上記窓枠を構成する上枠の下面に外れ止め片を装着し、この外れ止め片の下面を上記引戸障子の上縁に近接対向させる。
【０００６】
特に、本発明の引戸障子の外れ止め装置に於いては、上記上枠の下面には、下端開口部の幅が狭く、この下端開口部よりも上方に位置する溝本体部分の幅が広い係止溝が形成されている。又、上記外れ止め片は、合成樹脂により一体成形されたもので、この係止溝の溝本体部分にがたつきなく係合自在な基板部と、この基板部の中央部下面から下方に垂下された支柱部と、この支柱部の下半部外周面からこの支柱部の直径方向外方に突出した衝合部とから成る。そして、上記基板部は、互いに間隔をあけた状態で同一平面上に存在する１対の素子板から構成され、上記係止溝に、この係止溝から下方に抜け出る事はないが、これら両素子板を弾性変形させつつ、取付方向を鉛直軸を中心に互いに９０度異ならせた第一状態と第二状態との変換を自在に係合している。又、上記支柱部は、その下面中央部に、この支柱部を回転させて第一状態と第二状態とを変換する為の工具の先端部をほぼ隙間なく挿入自在な係合孔の下端部を開口させている。又、上記衝合部は、このうちの第一状態で上記上枠の長さ方向にその長さ方向を一致させて、その下面を上記引戸障子の上縁に対向しない状態となり、第二状態でその長さ方向を上記上枠の幅方向に一致させて、その下面を上記引戸障子の上縁に対向させる状態となる。
【０００７】
【作用】
上述の様に構成する本発明の引戸障子の外れ止め装置は、上枠下面の係止溝に係合させた外れ止め片を９０度回転させるのみで、外れ止め装置が機能する様にできる。即ち、窓枠を構成するサッシ材を造る工場等で上記外れ止め片を上記係止溝に係合させ、この外れ止め片を第一状態としておく。この第一状態では、衝合部の長さ方向と上枠の長さ方向とが一致して、この衝合部の下面が上記引戸障子の上縁に対向しない状態となる。この為、上記外れ止め片と引戸障子との位置関係に拘らず、この外れ止め片が引戸障子の建て込み作業の障害になる事はなく、この引戸障子の建て込み作業を容易に行なえる。又、この引戸障子の建て込み作業を完了した後には、上記外れ止め片を鉛直軸回りに９０度回転させて第二状態とし、上記衝合部の長さ方向を上記上枠の幅方向に一致させると共に、この上枠の長さ方向に関する外れ止め片の位置を適正にして、上記衝合部の下面を上記引戸障子の上縁に対向させれば、この引戸障子の浮き上がりを防止して、この引戸障子の外れ止めを図れる。
【０００８】
【発明の実施の形態】
図１〜１１は、本発明の実施の形態の第１例を示している。本発明の引戸障子の外れ止め装置を組み付ける引戸式窓装置は、図１１に示す様に、それぞれがアルミニウム合金の押し出し型材である、上枠１と下枠２と左右の竪枠３、３とから成る窓枠４の内側に、１対の引戸障子５、５を引き違い式に建て込んで成る。外れ止め装置は、上記上枠１の下面２個所位置に外れ止め片６、６を固定する事で構成している。そして、これら各外れ止め片６、６を、それぞれ上記１対の引戸障子５、５を閉鎖位置に移動させた状態でこれら各引戸障子５、５を構成する上框７、７の上縁に近接対向させる事により、これら各引戸障子５、５を構成する下框８、８に組み付けた戸車と、上記下枠２の上面に設けた下部案内レールとの係合が外れるのを防止するものである。
【０００９】
上記各外れ止め片６、６を装着自在とすべく、上記上枠１の下面で、それぞれが上記各引戸障子５、５の上端部を案内する為に設けた１対の上部案内レール９、９の間部分には、図１に示す様に、係止溝１０を形成している。この係止溝１０は、下端開口部１１の幅Ｗ₁₁が狭く、この下端開口部１１よりも上方に位置する溝本体部分１２の幅Ｗ₁₂が広い（Ｗ₁₁＜Ｗ₁₂）。
【００１０】
又、上記各外れ止め片６、６は、ポリアミド樹脂等の弾性を有する合成樹脂を射出成形する事により、全体を一体に形成したもので、基板部１３と支柱部１４と衝合部１５とを有する。このうちの基板部１３は、上記係止溝１０の溝本体部分１２にがたつきなく係合自在な形状及び大きさを有するもので、互いに間隔をあけた状態で同一平面上に存在する１対の素子板１６、１６により構成している。これら両素子板１６、１６は、互いに対向する内側縁の中間部で、それぞれ上記支柱部１４の基端部外周面と連続している。又、上記両素子板１６、１６の外周縁で互いに反対側に存在する部分は、互いに平行な１対の第一直線辺部１７、１７としている。上記基板部１３の自由状態で、これら両第一直線辺部１７、１７の外側縁同士の間隔Ｄ₁₇は、上記溝本体部分１２の幅Ｗ₁₂と同じか、この幅Ｗ₁₂よりも僅かに大きい（Ｄ₁₇≧Ｗ₁₂）。
【００１１】
又、上記両素子板１６、１６の外周縁でこれら両素子板１６、１６毎に互いに反対側に位置する部分は、それぞれが上記各第一直線辺部１７、１７に対し直角方向に存在し、互いに平行な１対の第二直線辺部１８、１８としている。又、上記両素子板１６、１６の外周縁でこれら両第二直線辺部１８、１８と反対側部分は、当該素子板１６、１６に設けた第一直線辺部１７、１７と他の素子板１６、１６に設けた第二直線辺部１８、１８の延長線とを滑らかに連続させる方向に湾曲した円弧部１９、１９としている。
【００１２】
尚、これら各円弧部１９、１９は、前記支柱部１４の中心軸をその中心とする円弧にほぼ一致する。又、前記基板部１３に関して反対側に存在する円弧部１９、１９同士の間隔Ｄ₁₉は、上記溝本体部分１２の幅Ｗ₁₂とほぼ同じ（Ｄ₁₉≒Ｗ₁₂）としている。又、上記各第一直線辺部１７、１７の長さ寸法Ｌ₁₇は、上記各素子板１６、１６の長さ寸法Ｌ₁₆の１／２を越える値としている（Ｌ₁₇＞Ｌ₁₆／２）。言い換えれば、前記支柱部１４の中心軸を通り、上記各第一直線辺部１７、１７に対し直角方向に存在する仮想直線は、上記各円弧部１９、１９とではなく、これら各第一直線辺部１７、１７と交差する。
【００１３】
更に、図示の例では、上記各素子板１６、１６の内側縁一端部で、それぞれ上記各第二直線辺部１８、１８から連続する部分に突片２０、２０を形成し、これら各突片２０、２０の先端部に、互いに反対方向に突出する突出部２１、２１を形成している。尚、これら両突出部２１、２１の中心同士を結ぶ線は、上記支柱部１４の中心軸を通過する。言い換えれば、これら両突出部２１、２１は、この支柱部１４に関して直径方向反対位置に存在する。
【００１４】
又、上記支柱部１４は、上記基板部１３の中央部下面から下方に垂下されたもので、下面中央部には、この支柱部１４を回転させる為の工具の先端部を係合させる為の係合孔２２の下端部を開口させている。図示の例では、この工具としてプラスドライバを使用する事を考慮して、上記係合孔２２を、適宜の大きさを有するプラスドライバの先端部をほぼ隙間なく挿入し、先端部を凹凸係合させる形状に形成している。
【００１５】
更に、前記衝合部１５は、上記支柱部１４の下半部の直径方向反対側２個所位置から、それぞれ直径方向に亙り突出した、１対の衝合片２３、２３から成る。これら各衝合片２３、２３の突出方向は、上記各素子板１６、１６の第一直線辺部１７、１７の方向に一致させている。従って、上記各衝合片２３、２３により構成する上記衝合部１５の長さ方向は、上記各第一直線辺部１７、１７の方向に一致している。
【００１６】
上述の様に構成する外れ止め片６は、前記図１１に示した上枠１の下面の所定部分に、上記基板部１３を上記係止溝１０に係合させる事により装着する。この装着作業は、前記窓枠４を構成するサッシ材を造る工場等で、上記上枠１を前記各竪枠３、３と組み合わせる以前に行なう。即ち、上記外れ止め片６の基板部１３を上記係止溝１０に、上記上枠１の端部から挿入する事により係合させ、この外れ止め片６を、図１０（Ａ）に示した第一状態、即ち、上記各第一直線辺部１７、１７が上記上枠１の長さ方向に向いた状態としておく。この第一状態では、上記衝合部１５の長さ方向と上記上枠１の長さ方向とが一致して、この衝合片１５の下面が前記各引戸障子５、５を構成する上框７、７の上縁に対向しない状態となる。この為、上記外れ止め片６と引戸障子５、５との位置関係に拘らず、この外れ止め片６が各引戸障子５、５の建て込み作業の障害になる事はなく、この引戸障子５、５の建て込み作業を容易に行なえる。又、この状態では、上記基板部１３が上記係止溝１０から下方に抜け出る事はない。
【００１７】
上記各引戸障子５、５の建て込み作業を完了した後には、上記外れ止め片６を、前記支柱部１４に設けた係合孔２２に下方から挿入したプラスドライバ等の工具により、鉛直軸回りに９０度回転させて、図１０（Ｂ）に示す様な第二状態とする。即ち、前記各素子板１６、１６の長さ方向一端部に形成した前記各第二直線辺部１８、１８を上記上枠１の長さ方向に向いた状態とすると共に、前記各突片２０、２０の先端部に形成した突出部２１、２１を、上記係止溝１０の内側面に突き当てる。この状態で、上記外れ止め片６の下端部に設けた前記衝合部１５の長さ方向が、上記上枠１の幅方向に一致する。又、この様な第二状態では、前記突片２０、２０の先端部に設けた突出部２１、２１が、上記係止溝１０の両内側面で、上記支柱部１４に関して直径方向反対側を弾性的に押圧する。この為、上記外れ止め片６の状態が、図１０（Ｂ）に示した第二状態から、不用意に動く事はない。又、この外れ止め片６が前記上枠１の長さ方向に不用意に動く事もない。
【００１８】
上記外れ止め片６を、上述の様にして第二状態とすると共に、上記上枠１の長さ方向に関するこの外れ止め片６の位置を、前記図１１に示した適正位置にする（実際には、第一状態のまま適正位置に移動した後、第二状態にする）。この状態で上記各引戸障子５、５を、窓開口を閉鎖する位置に移動させれば、上記衝合部１５の下面がこれら各引戸障子５、５の上縁に対向して、これら各引戸障子５、５の浮き上がりを防止し、これら各引戸障子５、５の外れ止めを図れる。この様に、本発明の引戸障子の外れ止め装置は、建設現場に於いては、上記上枠１の下面に設けた係止溝１０に係合させた外れ止め片６を、ドライバ等の簡便な工具で９０度回転させるのみで、外れ止め装置が機能する様にできる。
【００１９】
次に、図１２〜２１は、本発明の実施の形態の第２例を示している。本例の場合には、外れ止め片６ａの基板部１３ａを構成する１対の素子板１６ａ、１６ａの形状、並びに衝合部１５ａの形状を、上述した第１例の場合とは異ならせている。即ち、上記各素子板１６ａ、１６ａには、上述した第１例の様な突片２０、２０及び突出部２１、２１（図２、３、５、１０等参照）を設けていない。代わりに本例の場合には、上記衝合部１５ａを直方体状に形成し、長さ方向両端面中央部に、それぞれ突出部２１ａ、２１ａを形成している。上記衝合部１５ａの長さ方向両端寄り部分でこれら各突出部２１ａ、２１ａに整合する部分には、それぞれ中空部２４、２４を設けて、これら各突出部２１ａ、２１ａを弾性変形し易くしている。これら各突出部２１ａ、２１ａは、図２１（Ｂ）に示した第二状態で、上枠１の下面に設けた１対の上部案内レール９、９の互いに対向する側面に突き当たって、上記外れ止め片６ａが、図２１（Ｂ）に示した第二状態から不用意に変位する事を防止する。その他の構成及び作用は、上述した第１例の場合と同様である。
【００２０】
次に、図２２〜２５は、本発明に関する参考例として、引戸障子の外れ止め装置を構成する外れ止め片６、６（又は６ａ、６ａ）を利用して、召し合わせ框２５の上端面と窓枠４を構成する上枠１の中間部下面との間の隙間を塞ぐ上部風止め板２６を装着する構造を示している。従来から、窓枠４内に少なくとも１対の引戸障子５、５が引き違い式に建て込まれた構造に於いては、これら各引戸障子５、５を閉鎖状態に移動させた状態で、これら各引戸障子５、５の召し合わせ框２５の上端部と上枠１の中間部下面との間に生じる隙間を塞ぐべく、この中間部下面に上部風止め板を設ける事が行なわれている。この様な上部風止め板を上枠１の下面中間部に支持する為に従来は、実開昭６０−１２１０９９号公報、実公昭６１−２３１８９号公報等に記載されている様に、上部風止め板の両端部を上枠に対してねじ止めしていた。この為、この上部風止め板の装着作業が面倒であった。
【００２１】
これに対して本参考例の場合には、上記上部風止め板２６の両端部を、１対の外れ止め片６、６により、上記上枠１の中間部下面に支持固定する事で、上記上部風止め板２６の装着作業の容易化を図っている。更に本参考例の場合には、上記上部風止め板２６の両端部との係合に基づき、上記１対の外れ止め片６、６の、上記上枠１の長さ方向に亙る位置決めの確実性も確保している。
【００２２】
この為に本参考例の場合には、上記外れ止め片６、６を１対、上記両引戸障子５、５を閉鎖状態に移動した場合に互いに重なり合う召し合わせ框２５を、上記上枠１の長さ方向に関して両側から挟む位置に設けている。上記上部風止め板２６は、ポリプロピレン等の合成樹脂により造った取付板部２７と、ゴム、ビニール等のエラストマーにより造った風止め板部２８とから成る。この風止め板部２８は、上記取付板部２７の下面から間隔をあけた状態で垂下された複数枚の堰板部２９、２９により構成して、ラビリンス効果により、上記隙間を風が通過するのを防止する様にしている。
【００２３】
又、上記取付板部２７は、上記風止め板部２８を装着する中央部の両側に、それぞれ折れ曲がり部３０、３０を介して、それぞれ固定板部３１、３１を設けている。これら各固定板部３１、３１にはそれぞれ、上記取付板部２７の長さ方向両端縁に開口する係止切り欠き３２、３２を形成している。上記上部風止め板２６を上記上枠１の下面中間部に装着するには、上記各切り欠き３２、３２を上記各外れ止め片６、６を構成する支柱部１４、１４の上半部に係止する。
【００２４】
更に図示の例では、上記各外れ止め片６、６を前述の図１０（Ａ）に示した第一状態から、同図（Ｂ）に示した第二状態に変位させるのに伴って、上記各固定板部３１、３１を、上記上枠１の下面に抑え付ける様にしている。この為に図示の例では、上記各切り欠き３２、３２の周囲にそれぞれ、傾斜部３３、３３と平坦部３４とから成るカム突条３５、３５を形成している。又、上記各支柱部１４、１４の先半部に設けた衝合部１５を構成する１対の衝合片２３、２３の基半部上面で、上記各外れ止め片６、６の回転に伴って上記各カム突条３５、３５と摺動する部分にも、同様のカム面を形成している。上記各外れ止め片６、６を前述の図１０（Ａ）に示した第一状態から、同図（Ｂ）に示した第二状態に変位させると、上記各カム突条３５、３５と上記各カム面との係合に基づき、上記各衝合片２３、２３の基半部上面が、上記各固定板部３１、３１を、上記上枠の下面に強く押し付ける。この結果、これら各固定板部３１、３１を上記上枠の下面に固定すると共に、上記１対の外れ止め片６、６の、上記上枠１の長さ方向に亙る位置決め強度の向上も図れる。
【００２５】
尚、上述の様にして上記上部風止め板２６を上枠１の下面に装着するのは、必ずしも外れ止め片６、６を利用しなくても良い。即ち、上記上部風止め板２６を装着する為に、専用の係止具を用意しても良い。この様な係止具は、例えば、上記外れ止め片６、６から、衝合部１５を構成する１対の衝合片２３、２３の先半部を除いたものとする事ができる。
【００２６】
【発明の効果】
本発明の引戸障子の外れ止め装置は、以上に述べた通り構成され作用するので、建築現場での作業の簡略化により、工期の短縮化及び建設費の低廉化を図れる。

BACKGROUND OF THE INVENTION
The sliding door sliding device according to the present invention is incorporated in a window device for opening and closing a window opening of a building such as a general house or a building, and the sliding door sliding device moved to a closed state cannot be removed from the inside of the window frame. It is for doing.
[0002]
[Prior art]
As a window device for opening and closing the window opening of various buildings, a sliding door type window device that horizontally moves a sliding door shoji built in a window frame is widely used. In the case of such a sliding door type window device, for the purpose of crime prevention or ensuring safety, the sliding door shoji is prevented from floating when the sliding door shoji is moved to the closed state, and the sliding door shoji in the closed state does not come off from the window frame. Like. Therefore, conventionally, when a slip-off piece is attached to the lower surface of the upper frame constituting the window frame and the sliding door is moved to the closed state, the lower surface of the slip-off piece is placed on the sliding door. It is designed to be close to the edge. And the sliding door shoji is prevented from floating so that the engagement between the door wheel assembled on the lower arm of the sliding door shoji and the lower guide rail provided on the upper surface of the lower frame constituting the window frame is disengaged.
[0003]
As such a sliding door sliding device, devices described in Japanese Utility Model Publication No. 54-5337, Japanese Utility Model Publication No. 55-5647, and the like have been known. Of these, the structure described in Japanese Utility Model Laid-Open No. 54-5337 is a sliding door shoji that has a contact piece fixed to the lower end of the adjusting screw from below in a screw hole provided in a block locked to the lower surface of the upper frame. It is possible to face the upper edge of the head. Further, in the structure described in Japanese Utility Model Publication No. 55-5647, a slip-off block fixed by screwing to the lower surface of the upper frame is allowed to be close to and opposed to the upper edge of the sliding door screen.
[0004]
[Problems to be solved by the invention]
In the case of the conventional structure, in order to make the detachment prevention device actually function, the adjusting screw is rotated many times to sufficiently separate the contact piece from the lower surface of the upper frame (Japanese Utility Model Laid-Open No. 54-5337). In the case of the structure described in the publication, the work for fixing the locking block to the upper frame is necessary (in the case of the structure described in Japanese Utility Model Publication No. 55-5647), and the work is troublesome.
In view of such circumstances, the present invention has been invented to realize a sliding door sliding device that can simplify the work required to actually function.
[0005]
[Means for Solving the Problems]
The sliding door sliding device according to the present invention is similar to the sliding door sliding device that has been known in the past, and a door cart assembled to the lower arm of the sliding door sliding device built in a window frame so as to be horizontally movable. In order to prevent disengagement from the lower guide rail provided on the upper surface of the lower frame constituting the window frame, a detent piece is attached to the lower surface of the upper frame constituting the window frame. The lower surface is brought close to and opposed to the upper edge of the sliding door shoji.
[0006]
In particular, in the sliding door sliding device according to the present invention, a lower end opening is narrow on the lower surface of the upper frame, and a groove main body portion located above the lower end opening is wide. A stop groove is formed. Further, the above-mentioned detachment prevention piece is integrally formed of a synthetic resin, and is suspended downward from the lower surface of the central portion of the substrate portion, which can be engaged with the groove main body portion of the engagement groove without rattling. And an abutting portion protruding outward in the diameter direction of the support column from the outer peripheral surface of the lower half of the support column. Then, the base plate portion is composed of element plate of a pair existing on the same plane in a state spaced from each other, in the engagement grooves, but it is not exiting downwardly from the locking grooves, both these While the element plate is elastically deformed, the first state and the second state in which the mounting directions are different from each other by 90 degrees about the vertical axis are freely engaged. Further, the lower end portion of the engagement hole in which the tip end portion of the tool for rotating the support column portion to convert between the first state and the second state can be inserted almost without any gap at the center portion of the lower surface thereof. Is open. In addition, the abutting portion is in a state where the length direction of the upper frame coincides with the length direction of the upper frame in the first state, and the lower surface thereof does not face the upper edge of the sliding door shoji. Thus, the length direction is made to coincide with the width direction of the upper frame, and the lower surface thereof is opposed to the upper edge of the sliding door shoji.
[0007]
[Action]
The sliding door sliding device according to the present invention configured as described above can function so that the locking device functions only by rotating the locking member engaged with the locking groove on the lower surface of the upper frame by 90 degrees. That is, in a factory or the like that manufactures a sash material that constitutes the window frame, the above-mentioned stopper piece is engaged with the above-mentioned locking groove, and this stopper piece is set in the first state.

Further, in the example shown in the drawing, as each of the above-mentioned locking pieces 6 and 6 is displaced from the first state shown in FIG. 10A to the second state shown in FIG. Each of the fixed plate portions 31, 31 is pressed against the lower surface of the upper frame 1. For this reason, in the illustrated example, cam protrusions 35 and 35 each including an inclined portion 33 and 33 and a flat portion 34 are formed around the notches 32 and 32, respectively. Further, on the upper surface of the base half part of the pair of abutting pieces 23, 23 constituting the abutting part 15 provided in the front half part of each of the column parts 14, 14, the above-mentioned detent pieces 6, 6 are rotated. Accordingly, the same cam surface is also formed in the portion sliding with the cam protrusions 35 and 35. When each of the locking pieces 6 and 6 is displaced from the first state shown in FIG. 10A to the second state shown in FIG. 10B, the cam protrusions 35 and 35 and the Based on the engagement with the cam surfaces, the upper surfaces of the base half portions of the abutting pieces 23 and 23 strongly press the fixing plate portions 31 and 31 against the lower surface of the upper frame. As a result, the fixing plate portions 31 and 31 are fixed to the lower surface of the upper frame, and the positioning strength of the pair of retaining pieces 6 and 6 in the length direction of the upper frame 1 can be improved. .
[0025]
It should be noted that mounting the upper windshield plate 26 on the lower surface of the upper frame 1 as described above does not necessarily require the use of the stopper members 6, 6. That is, in order to mount the upper windshield plate 26, a dedicated locking tool may be prepared. Such a locking tool can be obtained, for example, by removing the first half of the pair of abutting pieces 23 and 23 constituting the abutting portion 15 from the above-described detachment preventing pieces 6 and 6.
