【発明の属する技術分野】
本発明は、クローゼットや部屋の間仕切り等、建物の開口部に、折戸又は開き戸の戸板を開閉自在に取り付ける戸板取付具に関する。
【０００２】
【従来の技術】
クローゼットや部屋の間仕切り等、建物の開口部に、折戸又は開き戸の戸板を開閉自在に取り付ける戸板取付具は、戸板への取り付けを確実にするため、戸板の生産工程で各戸板に設けた孔にハンマー等で打ち込んで取り付ける場合が一般的である。例えば、特許文献１に見られる戸板取付具（支持具）は、内部にばねを組み込んだプラスチック成形された筒状のケース（取付部）によって、上レール（開口部上縁に固着したガイドレール）内に嵌まり込むローラ（凸部材）を上端に装着した軸（旋回ピン）を上方付勢して進退自在に支持し、このケース（取付部）を戸パネル（戸板）に打ち込み固定して、取り付ける。
【０００３】
【特許文献１】
特開平８−２７７６７５号公報（３〜４頁、図１）
【０００４】
【発明が解決しようとする課題】
特許文献１が提案する戸板取付具は、作業上又は構造上にいくつかの問題点があった。まず、作業上の問題点として、ハンマーによる打ち込み作業を必要とし、打ち込む際の力加減が難しく、部品を壊す虞がある点を挙げることができる。また、戸板への取り付けを確実にするために接着剤を用いて固定するが、接着剤の保管管理や取扱いは容易でないほか、作業環境を悪化させる点も指摘することができる。
【０００５】
次に、構造上の問題点として、凸部材と旋回ピンの一部が戸板から突き出して輸送及び梱包効率を低下させる点を挙げることができる。また、輸送の際に突き出た凸部材に衝撃が加わって壊す虞がある点も指摘することができる。
【０００６】
このように、従来の戸板取付具には、作業上及び構造上の問題点があり、改善が望まれていた。そこで、戸板への取付は、ハンマーによる打ち込みや接着剤を不要として容易にし、施工現場で簡単かつ確実に各戸板に取り付けることのできる戸板取付具を開発するため、検討した。
【０００７】
【課題を解決するための手段】
検討の結果開発したものが、建物の開口部へ開閉自在に取り付ける戸板の上端面に一体に取り付ける取付部と、下面から下方に向けて突設した旋回ピンを前記取付部に枢着し、建物の開口部上縁に固着したガイドレールへ下方から嵌入する凸部材とからなる戸板取付具において、取付部は旋回ピンが貫通する深さで穿孔した軸孔にキー溝を刻設し、旋回ピンは軸孔より深い位置の側面から係止ピンを突出してなり、キー溝及び係止ピンは戸板の開閉操作に従う旋回ピンの通常旋回範囲外で水平位置を一致し、軸孔に旋回ピンを抜差自在となる位置関係にしたことを特徴とする戸板取付具である。
【０００８】
本発明の戸板取付具は、戸板の上端面に一体に取り付ける取付部に枢着する旋回ピンを介して凸部材を旋回自在に戸板に取り付ける。凸部材は、旋回ピンを上方から下方に向けて前記取付部に差し込んだ状態で、建物の開口部上縁に固着したガイドレールへ下方から嵌入するので、戸板の上端面から容易に離脱することがない。
【０００９】
取付部は、予め旋回ピンが貫通する深さで穿孔した軸孔にキー溝を刻設した構造を有し、この取付部を戸板の上端面へ一体に取り付けることで、抜止状態で旋回ピンを差し込む軸孔構造を戸板の上端面に容易に実現し、上端面に対する加工の手間を低減する。
【００１０】
ここで、前記キー溝と係止ピンとが戸板の開閉操作に従う旋回ピンの通常旋回範囲外で一致する位置関係であれば、戸板の通常使用時には、旋回ピンが軸孔から不用意に離脱する虞を防止できる。戸板取付具を戸板に取り付ける際には、旋回ピンの旋回範囲に制約がないため、前記のようなキー溝及び係止ピンの位置関係でも、軸孔へ旋回ピンを差し込むことは容易であるため、戸板取付具を戸板へ容易に取り付ける利便性は損ねない。
【００１１】
凸部材は、上面から上方に向けて一対の凸突起を突設してなり、両凸突起を同時にガイドレールへ嵌入することにより、各凸突起が互いに旋回を規制することでガイドレールに対する嵌入向きを一義的に定めた構成とする。また、凸部材は、ガイドレールへの嵌入部位から水平方向に進退する脱落防止材を前記嵌入部位に設けてなり、該嵌入部位をガイドレールに嵌入した状態で脱落防止材を進出させ、該脱落防止材をガイドレールの下縁フランジに係合することにより、凸部材がガイドレールからの脱落を防止すると好ましい。
【００１２】
より具体的には、凸部材は、上面から上方に向けてガイドレールへの嵌入部位である一対の凸突起を突設してなり、脱落防止材は前記一対の凸突起の間から水平方向に進退させるとよい。前記脱落防止材は、移動片及び係合片からなる断面Ｌ字状板材であり、凸部材へ差し込んだ調整ネジに前記移動片を螺合し、係合片を該凸部材から水平方向に突出した構造を例示できる。
【００１３】
また、凸部材は、下面と取付部との間に弾支部材を介装してなり、該弾支部材の復元力により戸板の上端面に対して上方へ付勢して弾支するとよい。弾支部材としてはコイルスプリングを例示できる。前記コイルスプリングは、凸部材の下面から突設する旋回ピンに遊嵌すると、コイルスプリングの特別な保持手段が不要になると共に、脱落する虞をなくすことができる。
【００１４】
【発明の実施の形態】
以下、本発明の実施形態について図を参照しながら説明する。図１は戸板取付具１を取り付けた固定側の戸板２と移動側の戸板３とからなるインナーセット形の折戸４を建物の開口部５に取りつけた扉開閉装置の側面図、図２は同扉開閉装置の折戸４を閉じた状態を表した平面図、図３は同扉開閉装置の折戸４を開いた状態の上端面６側を表した平面図、図４は同扉開閉装置の折戸４を開いた状態の下端面７側を表した平面図、図５は固定側の戸板２に取り付けた戸板取付具１の正面図、図６は戸板取付具１の戸板２，３に対する取付関係を表した分解斜視図、図７は戸板２，３の開閉操作と旋回ピン１０との関係（ａ）折戸４閉鎖時及び（ｂ）折戸４開放時それぞれを表した図８中Ａ−Ａ断面図、図８はガイドレール９に戸板取付具１の凸部材８を嵌入させた状態を表した断面図であり、図９はガイドレール９に戸板取付具１の凸部材８から脱落防止材３１を突出させた状態を表した断面図である。
【００１５】
本例の扉開閉装置は、図１〜図４に見られるように、屈曲関係で連結した固定側の戸板２と移動側の戸板３とからなるインナーセット形の折戸４を建物の開口部５に取り付けた構成である。本例では、開口部５上縁にのみガイドレール９を設け、開口部５下端縁は床面１２のままにしている。
【００１６】
固定側の戸板２は、図４及び図５に見られるように、ガイドレール９に締着した固着補助具１７を、上端面６側に位置する凸部材８に被せて拘束し、下端面７から下向きに突設した支持ピン１３を、開口部５下縁に固着する旋回受具１５で軸支してガイドレール９に沿った移動を拘束し、旋回のみする。
【００１７】
旋回ピン１０と同軸に位置する凸部材８は、図３に見られるように、凸突起３０，３０を同時にガイドレール９へ嵌入し、各凸突起３０，３０が互いに旋回を規制することでガイドレール９に対する凸部材８の嵌入向きをガイドレール９に対して一義的に定める。これにより、移動側の戸板３は、ガイドレール９に沿って移動しながら旋回ピン１０を中心に旋回する。
【００１８】
こうして、本例の扉開閉装置は、固定側及び移動側の戸板２，３がガイドレール９に傾倒を防止された状態で屈曲しながら開閉し、折戸４全体としては固定側の戸板２の旋回受具１５で支持された構成になっている。
【００１９】
本例のインナーセット形折戸４用の戸板取付具１は、図１〜３に見られるように、目隠し用の框１６を設けることにより、ガイドレール９及び凸部材８が前記框１６でほとんど隠すことができる。この戸板取付具１は、図６に見られるように、各戸板２，３の角部上端面へ一体に嵌合する取付部１８と、各戸板２，３の上端面６に対して枢着する旋回ピン１０を下面から下方に向けて突設し、上面から上方に向けて一対の凸突起３０，３０を突設した凸部材８とから構成している。
【００２０】
本例の取付部１８は、旋回ピン１０が貫通する深さで軸孔２０を穿孔した樹脂製ブロック体で、戸板２，３内にある鋼鈑の突き合わせリブ２１に設けた切欠２２と係合する差し込み溝２４内の係合突起２５により上端面６からの抜け止めを図っている。図示は省略するが、上端面６を塞ぐ型材（図９参照）の下面側に潜り込む突片を、隣接する取付部１８の側面から突設して押さえ込む構造にしておくとより確実な抜け止めが図られる。
【００２１】
軸孔２０には、点対称位置に一対のキー溝１９，１９を刻設しており、軸孔２０下端に対して軸孔２０断面と同形状の挿通孔２６を設けた金属製抜止板２７を嵌め込んでいる。また、旋回ピン１０と一体に昇降する凸部材８の下降代を確保するための窪み２３を上面に形成している。
【００２２】
金属製抜止板２７は、旋回ピン１０の係止ピン２８との擦れ合いによる摩耗や、旋回ピン１０に引き抜き荷重が掛かった際の係止ピン２８による破損がなく、前記係止ピン２８との係合を安定して保つことができる。実際には、旋回ピン１０はガイドレール９に嵌入した凸部材８によって常に下方に向けて押さえ込まれているため、係止ピン２８が金属製抜止板２７に擦れ合う機会は少ない（図９中、金属製抜止板２７と係止ピン２８との隙間を参照）。
【００２３】
凸部材８は、下面から下方に向けて旋回ピン１０を垂下し、上面から上方に向けて凸突起３０，３０を突設した外形略直方体状の樹脂ブロックからなる。
【００２４】
旋回ピン１０は、取付部１８に穿孔した軸孔２０より深い位置（正確には軸孔２０及び金属製抜止板２７の厚みの合計より深い位置）に係止ピン２８を貫通させ、側面から係止ピン２８の両端を突出させている。本例は、旋回ピン１０に遊嵌したコイルスプリング２９を、取付部１８の窪み２３との間に介装することで、凸部材８全体を上方へ付勢状態で弾支している。
【００２５】
旋回ピン１０は、各戸板２，３に直接穿孔した軸孔に差し込んでもよいが、戸板取付具１の各戸板２，３に対する取付を担う軸孔に対する旋回ピン１０の抜け止めを図ることが難しい。そこで、各戸板２，３の角部上端面へ一体に嵌合する取付部１８にキー溝１９を有する軸孔２０を穿孔することで、戸板２，３の上端面に容易にキー溝１９，１９付きの軸孔２０を設けることができるようにしている。
【００２６】
本例の凸部材８は、上面に設けた凸突起３０，３０を同時にガイドレール９へ嵌入することにより、各凸突起３０，３０が互いに旋回を規制することでガイドレール９に対する嵌入向きを一義的に定めている。
【００２７】
ガイドレール９へ嵌入する一対の凸突起３０，３０は、凸部材８の上面へ一体に形成しており、凸部材８と共に昇降する。脱落防止材３１は、移動片３２及び係合片３３からなる断面Ｌ字状金属片で、凸部材８へ水平方向に差し込んだ調整ネジ３４に移動片を螺合し、係合片３３を凸突起３０，３０間から水平方向に突出可能にしている。
【００２８】
戸板取付具１は、各戸板２，３の上端面６に嵌合した取付部１８に対して、前記旋回ピン１０及び凸部材８が一体に旋回する。また、凸部材８の昇降軌道は軸孔２０に差し込む旋回ピン１０によって規制されるため、全体として簡素な構成になっている。
【００２９】
本発明の特徴は、軸孔２０に旋回ピン１０を抜止状態で差し込むだけで、各戸板２，３の上端面６に戸板取付具１を取り付けることができる点にある。このため、取付に際しては軸孔２０に対して旋回ピン１０が抜き差し自在で、通常の扉開閉装置使用時には軸孔２０に対して旋回ピン１０が抜止状態にある必要がある。具体的には、軸孔２０に刻設したキー溝１９と旋回ピン１０から突出する係止ピン２８との水平面内における位置関係を特定して、前記取付及び抜止の選択を実現する。
【００３０】
戸板取付具１の凸部材８は、ガイドレール９に一対の凸突起３０，３０により回転不能に嵌入するから、ガイドレール９に対して向きを固定することになる。このため、折戸４の開閉操作により各戸板２，３を折り畳むと、凸部材８に対して各戸板２，３の向きが変化し、凸部材８に従う旋回ピン１０は戸板２，３に従う取付部１８の軸孔２０に対して旋回する。この戸板２，３の開閉操作に従う旋回ピン１０の軸孔２０に対する通常旋回範囲は、戸板２，３の向きの変化から、およそ０度（各戸板２，３が直線状に並ぶ閉状態）〜９０度（各戸板２，３を折り畳んだ開状態）である。
【００３１】
そこで、本例のキー溝１９と係止ピン２８とは、通常旋回範囲外である１３５度（凸部材８と戸板２，３との開度１３５度）の位置関係で一致し、軸孔２０に対して旋回ピン１０は抜き差し自在となる。これにより、戸板２，３の開閉操作に従う旋回ピン１０の通常旋回範囲（０〜９０度）では、図７（ａ）及び図７（ｂ）に見られるように、キー溝１９と係止ピン２８とが一致することはなく、抜け止めを図ることができる。
【００３２】
折戸４全体は、固定側の戸板２の下端面７に突設した支持ピン１３を、開口部５下縁に固着した旋回受具１５で軸支しており、戸板取付具１は折戸４の開閉に際して戸板２，３が傾倒し、開口部５から逸脱しないようにする働きが主であるため、キー溝１９から外れた位置における取付部１８への係止ピン２８の係合だけであっても、戸板２，３に対する戸板取付具１の取付強度に問題はない。
【００３３】
戸板取付具１の取付を終えた各戸板２，３は、まず下端面７の支持ピン１３を開口部５下縁の旋回受具１５に軸支させ、続いて凸部材８の凸突起３０，３０をガイドレール９に向けて嵌入するように引き起こすだけで、開口部５に対して組み付けることができる。コイルスプリング２９により上方へ付勢して弾支した凸部材８は、図８に見られるように、コイルスプリング２９を圧縮するように下方に向けて押さえることで下降し、框１６の邪魔になることはなく、ガイドレール９の直下に持って来ることができる。
【００３４】
ここで、コイルスプリング２９により上方へ付勢して弾支した凸部材８は、常態として凸突起３０，３０を突出させ、そのままではガイドレール９に嵌入できないが、図８に見られるように、凸部材８を作業者の手によって押し下げることで凸突起３０，３０をガイドレール９直下にまで持っていき、そのまま凸突起３０，３０を押し下げていた負荷を外すことで、自律的に凸部材８が復帰して凸突起３０，３０をガイドレール９に嵌入できる（図９参照）。
【００３５】
凸部材８は、コイルスプリング２９の付勢により上方に向けて付勢されており、ガイドレール９の下縁フランジ３５に凸突起３０以外の前後の部位を当接する。このため、戸板２の下端面７（旋回受具１５）側での高さ調整による凸部材８のガイドレール９に対する嵌入量調整を必要としない。固定側の戸板２側の凸部材８は、図５から明らかなように、凸突起３０，３０のガイドレール９への嵌入に加え、固着補助具１７への嵌入によって左右位置も規制される。なお、固着補助具１７の記載は図５のみとし他図では省略している。
【００３６】
こうして凸部材８の凸突起３０，３０をガイドレール９に嵌入できれば、開口部５への戸板２，３の取付は完了する。本発明では、更に戸板２，３の取付安定性を確保するため、ガイドレール９に嵌入した凸突起３０，３０からガイドレール９内に設けた引っ掛かりに向けて脱落防止材３１を突出させる。
【００３７】
本例の場合、調整ネジ３４は凸部材８に対して位置固定状態に差し込んでいるだけなので、この調整ネジ３４を右に回すと調整ネジ３４に螺合した脱落防止材３１が相対的に移動して（図９中右方向）、ガイドレール９の下縁フランジ３５に向けて凸突起３０，３０から係合片３３を突出させ、下縁フランジ３５の上方に位置させることができる。
【００３８】
凸部材８は、ガイドレール９の下縁フランジ３５の先端に当接して前後に位置規制されているため、係合片３３を突出させた脱落防止材３１の移動に関する自由度は低く、下縁フランジ３５との係合関係は解除されないので、通常使用でガイドレール９から凸部材８が抜け落ちて戸板２，３が外れる虞がなくなる。
【００３９】
開き戸の扉開閉装置を構成するには、上述の例（図１以下参照）と全く同じ構造の戸板取付具１を戸板２の上端面６側の側端部に枢着する。戸板２は、図５に見られるように、戸板取付具１の凸部材８を、前記ガイドレール９に締着した固着補助具１７に嵌入して拘束し、下端面から突設した支持ピン１３を開口部５側縁下端位置に固着する旋回受具１５により軸支して取り付けて、旋回可能にする。すなわち、上述の折戸の扉開閉装置の例の移動側の戸板３を廃して固定側の戸板２のみの構成とし、固定側の戸板２は上述の折戸の扉開閉装置の例と全く同じ構造にすればよい。
【００４０】
これは、折戸及び開き戸の違いなく、部材を共通化できることを意味する。これにより、製品コストを引き下げることができるほか、同一建物内で折戸と開き戸を建て付ける場合の部材管理や取り付けの手間を大幅に減らすことが可能となる。
【００４１】
【発明の効果】
本発明により、戸板への取付に際しては工具を不要とするほどに取付作業を容易にし、施工現場で簡単に戸板に取り付けることのできる戸板取付具を提供できるようになる。これは、通常旋回範囲外でのみ戸板側の軸孔へ抜き差し自在な旋回ピンと取付部の構成により得られる効果である。
【００４２】
作業上の改善点として、本発明の戸板取付具は、ハンマーによる打ち込み作業を必要とすることなく戸板に取り付けることができ、施工現場での取付作業を可能とする。特に、取扱いや保管管理が難しく作業環境を悪化させてしまう接着剤を使用しなくても取付作業ができる利点がある。
【００４３】
構造上の改善点として、本発明の戸板取付具は、輸送時において戸板から凸部材及び旋回ピンが突出しない利点がある。凸部材及び旋回ピンは、施工現場で取り付けるので、輸送及び梱包効率を高めることができる。また、従来のように輸送中に戸板取付具が損傷する心配をしなくてよくなる。このように、本発明の戸板取付具は、作業上及び構造上の改善点をもたらす効果を有する。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a door plate attachment for freely opening and closing a folding or hinged door plate at an opening of a building, such as a closet or a room partition.
[0002]
[Prior art]
Door plate fittings that allow the door plate of a folding door or hinged door to open and close freely in the opening of the building, such as a closet or room partition, etc., in the holes provided in each door plate in the production process of the door plate to ensure the attachment to the door plate It is common to hammer in and attach. For example, a door plate mounting device (supporting device) disclosed in Patent Literature 1 has an upper rail (a guide rail fixed to an upper edge of an opening) by a plastic molded cylindrical case (mounting portion) in which a spring is incorporated.

[0003]
[Patent Document 1]
JP-A-8-277675 (pages 3 and 4, FIG. 1)
[0004]
[Problems to be solved by the invention]
The door plate fixture proposed in Patent Literature 1 has some problems in work or structure. First, as a problem in the operation, a driving operation by a hammer is required, it is difficult to control a force at the time of driving, and there is a possibility that components may be broken. In addition, it is fixed using an adhesive to ensure the attachment to the door plate. However, it can be pointed out that storage management and handling of the adhesive are not easy, and that the working environment is deteriorated.
[0005]
Next, as a structural problem, a part of the convex member and the pivot pin protrudes from the door plate to lower transportation and packing efficiency. Further, it can be pointed out that there is a possibility that the protruding member protruding at the time of transportation may be damaged by an impact.
[0006]
As described above, the conventional door plate fixture has problems in operation and structure, and improvement has been desired. In order to develop a door plate attachment that can be easily and securely attached to each door plate at the construction site, we studied the installation to the door plate by eliminating the need for hammering and adhesive.
[0007]
[Means for Solving the Problems]
As a result of the examination, the building developed by attaching a mounting portion integrally attached to the upper end surface of a door plate that can be freely opened and closed to the opening of the building, and a pivot pin projecting downward from the lower surface to the mounting portion, A door member comprising a convex member fitted into a guide rail fixed to the upper edge of the opening from below, wherein the mounting portion has a keyway engraved in a shaft hole drilled at a depth penetrated by the pivot pin. The locking pin protrudes from the side surface at a position deeper than the shaft hole.The key groove and the locking pin match the horizontal position outside the normal turning range of the turning pin according to the opening and closing operation of the door plate, and the turning pin is pulled out of the shaft hole. A door plate fixture characterized in that the positional relationship is such that it can be freely changed.
[0008]
In the door plate fixture of the present invention, the convex member is pivotally attached to the door plate via a pivot pin pivotally attached to a mounting portion integrally attached to the upper end surface of the door plate. The convex member is inserted from below into the guide rail fixed to the upper edge of the opening of the building in a state where the pivot pin is inserted into the mounting portion from above to below, so that it can easily be detached from the upper end surface of the door plate. There is no.
[0009]
The mounting portion has a structure in which a keyway is cut into a shaft hole that has been drilled in advance to a depth through which the pivot pin penetrates, and the mounting portion is integrally attached to the upper end surface of the door plate, so that the pivot pin can be prevented from being removed. The shaft hole structure to be inserted is easily realized on the upper end surface of the door plate, and the labor for processing the upper end surface is reduced.
[0010]
Here, if the key groove and the locking pin coincide with each other outside the normal turning range of the turning pin according to the opening and closing operation of the door plate, the turning pin may be accidentally detached from the shaft hole during normal use of the door plate. Can be prevented. When attaching the door plate fixture to the door plate, since there is no restriction on the turning range of the turning pin, it is easy to insert the turning pin into the shaft hole even with the positional relationship between the key groove and the locking pin as described above. In addition, the convenience of easily attaching the door plate fixture to the door plate is not impaired.
[0011]
The projecting member has a pair of projecting projections projecting upward from the upper surface, and by fitting both projecting projections into the guide rail at the same time, each projecting projection restricts turning with respect to each other so that the fitting direction with respect to the guide rail is achieved. Is defined uniquely. Further, the projecting member is provided with a falling-off preventing member which advances and retreats in a horizontal direction from a fitting portion to the guide rail, and makes the falling-off preventing material advance in a state where the fitting portion is fitted to the guide rail, and It is preferable that the protruding member is prevented from falling off the guide rail by engaging the prevention member with the lower edge flange of the guide rail.
[0012]
More specifically, the projecting member is formed by projecting a pair of projecting projections, which are portions to be fitted into the guide rails, from the upper surface to the upper side, and the falling-off prevention member is horizontally arranged from between the pair of projecting projections. It is good to go back and forth. The falling-off prevention member is an L-shaped cross-section plate member including a moving piece and an engaging piece. The moving piece is screwed into an adjusting screw inserted into the convex member, and the engaging piece projects in a horizontal direction from the convex member. Can be exemplified.
[0013]
The projecting member may be provided with an elastic member interposed between the lower surface and the mounting portion, and may be urged upward against the upper end surface of the door plate by the restoring force of the elastic member to be elastically supported. A coil spring can be exemplified as the elastic member. When the coil spring is loosely fitted on a pivot pin projecting from the lower surface of the convex member, a special holding means for the coil spring is not required, and the possibility of falling off can be eliminated.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION

[0015]
As shown in FIGS. 1 to 4, the door opening / closing device of the present embodiment includes an inner set-shaped folding door 4 including a fixed-side door plate 2 and a moving-side door plate 3 that are connected in a bending relationship. It is a configuration attached to. In this example, the guide rail 9 is provided only on the upper edge of the opening 5, and the lower edge of the opening 5 is left as the floor surface 12.
[0016]
As shown in FIGS. 4 and 5, the fixed side door plate 2 restrains the fixing aid 17 fastened to the guide rail 9 by covering the fixing member 17 on the convex member 8 located on the upper end surface 6 side. The support pin 13 protruding downward from the shaft is pivotally supported by a swivel holder 15 fixed to the lower edge of the opening 5 to restrict movement along the guide rail 9 and only swing.
[0017]
As shown in FIG. 3, the convex member 8 coaxial with the pivot pin 10 has the convex protrusions 30, 30 simultaneously fitted into the guide rail 9, and the respective convex protrusions 30, 30 restrict the rotation of each other to guide the guide. The fitting direction of the convex member 8 with respect to the rail 9 is uniquely determined with respect to the guide rail 9. Thereby, the moving side door plate 3 turns around the turning pin 10 while moving along the guide rail 9.
[0018]
In this manner, the door opening and closing device of this embodiment opens and closes while bending while the fixed side and moving side door plates 2 and 3 are prevented from being tilted by the guide rail 9, and the folding door 4 as a whole turns the fixed side door plate 2. It is configured to be supported by the receiver 15.
[0019]
As shown in FIGS. 1 to 3, the door plate attachment 1 for the inner set type folding door 4 of the present embodiment is provided with a blind frame 16 so that the guide rail 9 and the convex member 8 are almost hidden by the blind frame 16. be able to. As shown in FIG. 6, the door plate attachment 1 is attached to an attachment portion 18 which is integrally fitted to a corner upper end surface of each door plate 2, 3, and pivotally attached to an upper end surface 6 of each door plate 2, 3. And a convex member 8 having a pair of convex protrusions 30 protruding downward from the lower surface and projecting upward from the upper surface.
[0020]
The mounting portion 18 of this embodiment is a resin block body having a shaft hole 20 perforated at a depth through which the pivot pin 10 penetrates, and engages with a notch 22 provided in a butt rib 21 of a steel plate in the door plates 2 and 3. The engagement projection 25 in the insertion groove 24 prevents the upper end surface 6 from coming off. Although illustration is omitted, a more reliable retaining structure can be obtained if the projecting piece that sneaks into the lower surface side of the profile material (see FIG. 9) that closes the upper end surface 6 is configured to be protruded from the side surface of the adjacent mounting portion 18 and pressed down. It is planned.
[0021]
The shaft hole 20 is provided with a pair of key grooves 19, 19 at point symmetric positions, and a metal retaining plate 27 having an insertion hole 26 having the same shape as the cross section of the shaft hole 20 at the lower end of the shaft hole 20. Is fitted. In addition, a recess 23 is formed on the upper surface to secure a descending allowance of the convex member 8 which moves up and down integrally with the pivot pin 10.
[0022]
The metal retaining plate 27 is free from abrasion due to the rubbing of the turning pin 10 with the locking pin 28, and is not damaged by the locking pin 28 when a pulling load is applied to the turning pin 10; Engagement can be kept stable. Actually, since the turning pin 10 is always pressed down by the convex member 8 fitted into the guide rail 9, there is little chance that the locking pin 28 rubs against the metal retaining plate 27 (see FIG. (See the gap between the locking plate 27 and the locking pin 28).
[0023]
The protruding member 8 is formed of a resin block having a substantially rectangular parallelepiped shape in which the revolving pin 10 is hung downward from the lower surface, and the protruding protrusions 30 are projected upward from the upper surface.
[0024]
The pivot pin 10 allows the locking pin 28 to penetrate a position deeper than the shaft hole 20 drilled in the mounting portion 18 (more precisely, a position deeper than the total thickness of the shaft hole 20 and the metal retaining plate 27), and engages from the side. Both ends of the stop pin 28 are projected. In the present embodiment, the coil spring 29 loosely fitted to the pivot pin 10 is interposed between the coil spring 29 and the recess 23 of the mounting part 18 to elastically support the entire convex member 8 upward.
[0025]
The pivot pin 10 may be inserted into a shaft hole directly perforated in each door plate 2, 3, but it is difficult to prevent the pivot pin 10 from coming off the shaft hole that is responsible for mounting the door plate fixture 1 to each door plate 2, 3. . Therefore, by drilling a shaft hole 20 having a key groove 19 in the mounting portion 18 which is fitted integrally with the corner upper end surface of each door plate 2, 3, the key groove 19, A shaft hole 20 with 19 can be provided.
[0026]
The convex member 8 of the present example is configured such that the convex protrusions 30 provided on the upper surface are simultaneously fitted into the guide rail 9, thereby restricting the respective protrusions 30, 30 from rotating with each other, so that the fitting direction with respect to the guide rail 9 is unified. Stipulated.
[0027]
The pair of protrusions 30, 30 fitted into the guide rail 9 are formed integrally on the upper surface of the protrusion 8, and move up and down together with the protrusion 8. The falling-off prevention member 31 is an L-shaped metal piece having a cross section composed of a moving piece 32 and an engaging piece 33. The moving piece is screwed into an adjusting screw 34 inserted horizontally into the convex member 8, and the engaging piece 33 is made convex. The projections 30 can be projected horizontally between the projections 30.
[0028]
In the door plate fixture 1, the pivot pin 10 and the convex member 8 pivot integrally with a mounting portion 18 fitted to the upper end surface 6 of each of the door plates 2 and 3. Further, since the elevating trajectory of the convex member 8 is regulated by the turning pin 10 inserted into the shaft hole 20, the configuration is simple as a whole.
[0029]
A feature of the present invention is that the door plate fixture 1 can be attached to the upper end surfaces 6 of the door plates 2 and 3 simply by inserting the turning pin 10 into the shaft hole 20 in a locked state. For this reason, it is necessary that the pivot pin 10 can be freely inserted into and removed from the shaft hole 20 at the time of mounting. Specifically, the positional relationship between the key groove 19 formed in the shaft hole 20 and the locking pin 28 protruding from the pivot pin 10 in a horizontal plane is specified, and the selection of the mounting and the retaining is realized.
[0030]
Since the convex member 8 of the door plate fixture 1 is non-rotatably fitted into the guide rail 9 by the pair of convex protrusions 30, the direction is fixed to the guide rail 9. For this reason, when each door plate 2, 3 is folded by opening and closing operation of the folding door 4, the direction of each door plate 2, 3 changes with respect to the convex member 8, and the pivot pin 10 according to the convex member 8 is attached to the mounting portion according to the door plates 2, 3. It turns with respect to the shaft hole 20 of 18. The normal turning range of the turning pin 10 with respect to the shaft hole 20 according to the opening / closing operation of the door plates 2 and 3 is approximately 0 degrees (closed state in which the door plates 2 and 3 are linearly arranged) from a change in the direction of the door plates 2 and 3. It is 90 degrees (the doors 2 and 3 are folded open).
[0031]
Therefore, the keyway 19 and the locking pin 28 of the present example coincide with each other in a positional relationship of 135 degrees (135 degrees between the convex member 8 and the door plates 2 and 3) outside the normal turning range, and the shaft hole 20 is formed. The pivot pin 10 can be freely inserted and removed. Thus, in the normal turning range (0 to 90 degrees) of the turning pin 10 according to the opening and closing operations of the door plates 2 and 3, as shown in FIGS. 7A and 7B, the keyway 19 and the locking pin 28 does not match, and it is possible to prevent slippage.
[0032]
The folding door 4 as a whole supports a support pin 13 projecting from the lower end face 7 of the fixed side door plate 2 with a swivel holder 15 fixed to the lower edge of the opening 5. The main function of the door plates 2 and 3 to prevent the door plates 2 and 3 from inclining during opening / closing and to deviate from the opening 5 is only engagement of the locking pin 28 with the mounting portion 18 at a position deviated from the key groove 19. However, there is no problem in the mounting strength of the door plate fixture 1 to the door plates 2 and 3.
[0033]
After the door plates 2 and 3 have been attached to the door plate attachment 1, the support pins 13 on the lower end surface 7 are first pivotally supported by the turning receiver 15 at the lower edge of the opening 5, and then the projections 30 and The assembly can be assembled to the opening 5 simply by causing the fitting 30 to be fitted toward the guide rail 9. As shown in FIG. 8, the convex member 8 urged upward by the coil spring 29 and elastically supported is lowered by pressing the coil spring 29 downward so as to compress it, and obstructs the frame 16. And can be brought directly below the guide rail 9.
[0034]
Here, the projecting member 8 urged upward by the coil spring 29 and elastically supports the projecting projections 30 and 30 in a normal state, and cannot be fitted into the guide rail 9 as it is, but as shown in FIG. The protruding member 8 is pushed down by the operator's hand to bring the protruding protrusions 30 and 30 directly below the guide rail 9, and by removing the load that has pressed down the protruding protrusions 30 and 30, the protruding member 8 autonomously. Is restored, and the protrusions 30, 30 can be fitted into the guide rail 9 (see FIG. 9).
[0035]
The protruding member 8 is urged upward by the urging of the coil spring 29, and the front and rear portions other than the protruding protrusion 30 abut on the lower edge flange 35 of the guide rail 9. For this reason, it is not necessary to adjust the fitting amount of the convex member 8 to the guide rail 9 by adjusting the height on the lower end surface 7 (the turning receiver 15) side of the door plate 2. As is clear from FIG. 5, the left and right positions of the convex member 8 on the fixed side door plate 2 side are regulated by the fitting of the projections 30 into the guide rail 9 and the fitting into the fixing aid 17. The illustration of the fixing aid 17 is only shown in FIG. 5 and is omitted in other drawings.
[0036]
When the protrusions 30, 30 of the protrusion member 8 can be fitted into the guide rail 9, the mounting of the door plates 2, 3 to the opening 5 is completed. In the present invention, in order to further secure the mounting stability of the door plates 2 and 3, the falling-off prevention member 31 is projected from the convex protrusions 30 and 30 fitted into the guide rail 9 toward the catch provided in the guide rail 9.
[0037]
In the case of this example, since the adjusting screw 34 is merely inserted in the position fixed state with respect to the convex member 8, when the adjusting screw 34 is turned clockwise, the falling-off preventing material 31 screwed to the adjusting screw 34 relatively moves. Then (rightward direction in FIG. 9), the engaging piece 33 is projected from the projections 30, 30 toward the lower edge flange 35 of the guide rail 9, and can be positioned above the lower edge flange 35.
[0038]
Since the convex member 8 is in contact with the tip of the lower edge flange 35 of the guide rail 9 and its position is regulated in the front and rear directions, the degree of freedom regarding the movement of the falling-off prevention member 31 from which the engagement piece 33 is projected is low, and the lower edge Since the engagement relationship with the flange 35 is not released, there is no danger that the convex members 8 fall out of the guide rails 9 in normal use and the door plates 2 and 3 come off.
[0039]
In order to construct a door opening / closing device for a hinged door, a door plate fixture 1 having exactly the same structure as that of the above-described example (see FIG. 1 and subsequent figures) is pivotally attached to a side end of the door plate 2 on the upper end surface 6 side. As shown in FIG. 5, the door plate 2 fits the convex member 8 of the door plate fixture 1 into a fixing aid 17 fastened to the guide rail 9 and restrains the same, and the support pin 13 protrudes from the lower end surface. Is pivotally mounted by a swivel holder 15 fixed to the lower end position of the side edge of the opening 5 to enable swiveling. That is, the moving-side door plate 3 of the above-mentioned folding door door opening / closing device is eliminated and only the fixed side door plate 2 is provided, and the fixed-side door plate 2 has exactly the same structure as the above-mentioned folding door door opening / closing device. do it.
[0040]
This means that the members can be shared, regardless of whether the door is a folding door or a hinged door. As a result, it is possible to reduce the product cost, and it is possible to significantly reduce the time and labor for managing and installing members when installing a folding door and a hinged door in the same building.
[0041]
