Description

【０００１】
【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である建物の開口部に、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、輸送及び梱包効率を高めるため、施工現場で各戸板に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(折戸用金具)は、縦板部を折戸(戸板)の上端部背面に宛い、取付孔を通じて螺着する皿ネジにより締め付けて、取り付ける。また、折戸(戸板)を据え付ける折には、ガイドピース(戸板取付具)の凸部(凸部材)をレール(開口部下縁に固着したガイドレール)に嵌め、次いで折戸(戸板)を持ち上げながら折戸(戸板)の下端部背面に取り付けた戸車をレールに載せる。
【０００３】
【特許文献１】
特許第3312021号公報（３〜６頁、図９）
【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、戸板に取り付ける多数の皿ネジを必要とし、上述のような現場での取付作業としては煩わしく、ドライバーがなければ取付作業ができない点を挙げることができる。また、建物の開口部に戸板を取り付ける作業は、重い戸板を持ち上げる労力を課すほか、例えばガイドレールにうまく凸部材を嵌入できず、戸板を転倒させるという危険性を招く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、ガイドレールに対する凸部材の嵌入量を適当に設定しにくい点を挙げることができる。上記戸板の取付作業からも分かるように、戸板取付具の凸部材は、取付に際して深くガイドレールに嵌入でき、取付後はガイドレールに対して下がりながらも必要十分に係合していることが望ましい。
【０００６】
しかし、建物の開口部は寸法精度が低く、開口部上縁(鴨居)に固着するガイドレールの高さがばらつく結果、ガイドレールに対する凸部材の嵌入量の適当な設定ができなかった。また、こうしたガイドレール及び凸部材の関係は、戸車が外れる程度に凸部材がガイドレール内に嵌入する虞れを残し、戸板が外れる危険性を招いていた。このため、従来の戸板には別途戸車側に高さ調整手段を設ける例が少なくなかった。
【０００７】
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、戸板への取付は工具不要で容易にし、建物の開口部へ簡単に戸板を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。特に、ガイドレールに嵌入する凸部材について構造を検討し、戸板の取付作業を容易にすると共に、ガイドレールに対する適当な嵌入量を実現しやすい構造を目標として検討した。
【０００８】
【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旋回ピンを枢着する取付部と、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を、この戸板の裏面側で前記旋回ピンを軸に旋回させる案内部とからなり、案内部は凸部材を上方へ付勢して弾支してなる戸板取付具において、取付部は、戸板の上端面へ一体に嵌合する取付基部と、旋回ピンを突設するピン基部とからなり、取付基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、ピン基部は軸孔より深い位置の旋回ピン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ある戸板取付具である。これは、戸板上端部をガイドレール前面側に配置して戸板を開口部に取り付けるアウターセット扉用の戸板取付具である。この戸板取付具は戸板の裏面側に隠れて前面からはほとんど見えない。
【０００９】
具体的な案内部は、凸部材を収納してこの凸部材の昇降方向及び昇降範囲を規制する案内本体に対してこの凸部材を上方へ付勢して弾支する構成がよい。
【００１０】
本発明の戸板取付具は、戸板の上端面に旋回ピンを枢着する取付部の前記旋回ピンを介して案内部を旋回自在に戸板に取り付ける。旋回ピンは上方から下方に向けて前記上端面に差し込むことになるので、通常上端面から容易に離脱しない。これから、この取付部は、単に上端面へ旋回ピンを旋回自在に差し込む構成でよい。これにより、戸板に対する戸板取付具の取付は容易になり、例えば戸板には旋回ピンを差し込む軸孔だけを穿孔しておけばよいことになる。しかし、戸板に対する戸板取付具の取付安定性を鑑みた場合、取付部は抜止状態で上端面へ旋回ピンを旋回自在に差し込む構成にすることが好ましい。
【００１１】
具体的な取付部は、戸板の上端面へ一体に嵌合する取付基部と、旋回ピンを突設するピン基部とからなり、取付基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、ピン基部は軸孔より深い位置の旋回ピン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ある構成とする。
【００１２】
上記取付部は、旋回ピンを差し込む軸孔を穿孔した取付基部を戸板の上端面へ一体に嵌合することで、抜止状態で旋回ピンを差し込む軸孔構造を容易に実現し、上端面に対する加工の手間を低減する。係止ピンを設けた旋回ピンは、軸孔のキー溝と前記係止ピンとが一致しない限り、抜け止めが図られる。
【００１３】
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れを防止できる。ピン基部を取付基部に取り付ける際は、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。
【００１４】
また、本発明の戸板取付具は、従来取付具本体(本発明の案内部に相当)と一体に設けていた凸部材を案内部と別体に構成し、更に案内部に対して上方へ付勢して弾支した。これは、凸部材が案内部に対して出没自在であることを意味する。これにより、案内部から凸部材が大きく突出していても、戸車を開口部下縁に固着したガイドレールに載せるために必要な持ち上げ量を前記凸部材の没入によって確保できる。
【００１５】
このほか、戸板を開口部に取り付ける際、例えば框に当たって没入した凸部材も、ガイドレール直下に至った段階で付勢により自律的に突出してこのガイドレールに嵌入できたり、ガイドレールに対する嵌入量を案内部からの凸部材の突出量で調整できるため、従来のように戸車側に高さ調整手段を設ける必要性を低減又はなくすことができる。
【００１６】
案内部は、ガイドレールに嵌入した凸部材からこのガイドレールの内側壁に向けて出没する脱落防止材をこの凸部材に設けておくとよい。この案内部は、脱落防止材をガイドレールの内側壁に向けて突出させることで、ガイドレール(より具体的にはガイドレールの下縁フランジ)に脱落防止材を係合させ、ガイドレール内における凸部材の自由度を制限することにより、ガイドレールから不用意に凸部材が離脱することを防止できる。
【００１７】
具体的な脱落防止材は、移動片及び係合片からなる断面Ｌ字状板材を例示できる。この脱落防止材は、凸部材に差し込んだ調整ネジに前記移動片を螺合し、係合片をこの凸部材から水平方向に突出して構成する。
【００１８】
上記戸板取付具を用いれば、折戸又は開き戸は次のように構成できる。折戸は、建物の開口部へ屈曲自在に取り付ける折戸用の一対の戸板と、前記開口部上縁に固着したガイドレールと、前記各戸板の外側端部の上端面に枢着してガイドレールへ嵌合する戸板取付具とからなる扉開閉装置において、各戸板取付具はガイドレールへ下方から嵌入する凸部材を上方へ付勢して弾支したことを特徴とする建物の開口部に折戸を取り付けた扉開閉装置となる。
【００１９】
また、開き戸は、建物の開口部へ開閉自在に取り付ける開き戸用の戸板と、前記開口部上縁に固着したガイドレールと、前記戸板の上端面の一端に枢着してガイドレールへ嵌合する戸板取付具とからなる扉開閉装置において、各戸板取付具はガイドレールへ下方から嵌入する凸部材を上方へ付勢して弾支したことを特徴とする建物の開口部に開き戸を取り付けた扉開閉装置となる。
【００２０】
【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は本例の戸板取付具１を取り付けた固定側及び移動側の戸板２,３からなるアウターセット形の折戸４を建物の開口部５に取り付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は移動側の戸板３に取り付けた戸板取付具１の側面図、図７は図６中Ａ−Ａ断面図、図８は戸板取付具１の分解斜視図、図９は戸板取付具１の戸板２に対する取付関係を表した分解斜視図、図10は戸板２の開閉操作と旋回ピン８との関係(a)戸板取付具１装着時、(b)折戸４閉鎖時及び(c)折戸４開放時それぞれを表した断面図、図11はガイドレール９に戸板取付具１の凸部材10を嵌入させているところの状態を表した断面図、図12はガイドレール９に戸板取付具１の凸部材10から脱落防止材11を突出させた状態を表した断面図であり、図13は別例の取付部を用いて開き戸に取り付けた戸板取付具の戸板に対する取付関係を表した分解斜視図である。
【００２１】
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及び移動側の戸板２,３からなるアウターセット形の折戸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。固定側の戸板２は、図５に見られるように、裏面側に位置する戸板取付具１の案内部13を、前記ガイドレール９に締着した固着補助具14に嵌入して拘束し、下端面を開口部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、旋回のみ可能にする。
【００２２】
移動側の戸板３は、図６に見られるように、上端面６に取り付けた戸板取付具１の凸部材10を前記ガイドレール９に直接嵌入し、ガイドレール９に沿って移動しながら旋回する。すなわち、本例の扉開閉装置は、折戸４全体としては固定側の戸板２の旋回受具15で支持されるとともに固着補助具14により傾倒を防止された状態で旋回し、移動側の戸板３がガイドレール９に案内された状態で折戸４全体として屈曲しながら開閉する構成である。
【００２３】
戸板取付具１は、図７〜図９に見られるように、各戸板２,３の上端面６に対して旋回ピン８を枢着する取付部16と、ガイドレール９へ下方から嵌入する凸部材10を上方へ付勢して弾支した案内部13とからなる。取付部16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８の抜け止めを図ることが難しい。
【００２４】
そこで、本例の取付部16は、各戸板２,３の角部上端面へ一体に嵌合する取付基部17と、旋回ピン８を突設する平板状のピン基部18とから構成し、前記取付基部17にキー溝19を有する軸孔20を穿孔している。
【００２５】
取付基部17は、旋回ピン８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、予め各戸板２,３の角部上端面へ取り付けた状態で戸板内の空間にウレタン樹脂を注入発泡させ接着一体化する。加えて、戸板内にある表面側と裏面側の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23内の係合突起24により上端面６からの確実な抜け止めを図っている。
【００２６】
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、隣接する取付基部17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。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25を設けた金属製抜止板26を嵌め込んでいる。
【００２７】
金属製抜止板26は、樹脂製取付基部17に比べ、係合する旋回ピン８の係止ピン27との擦れ合いによる磨耗や、旋回ピン８に引き抜き荷重が掛かった際の係止ピン27による破損がなく、前記係止ピン27との係合を安定して保つことができる。
【００２８】
ピン基部18は、案内部13の案内本体28から戸板に向かって前方に延設して水平に折り曲げた板面で、旋回ピン８を垂下する基礎である。旋回ピン８は、取付基部17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26の厚みの合計より深い位置)に係止ピン27を貫通させ、側面から係止ピン27の両端を突出させている。戸板取付具１は、各戸板２,３角部の上端面６に嵌合した取付基部17に対して相対的に、前記旋回ピン８からピン基部18及び案内部13が一体に旋回する。
【００２９】
案内部13は、上記板材からなるピン基部18を延設する外形箱型の金属製案内本体28と、この案内本体28へ昇降自在に嵌め込んだ樹脂ブロックの凸部材10とからなり、案内本体28及び凸部材10の間に上方へ反発するコイルスプリング29を介装し、凸部材10を上方へ付勢することにより弾支している。本例では、上面にガイドレール９へ嵌入する一対の凸突起30,30を一体に形成した全体が昇降する構成である。
【００３０】
脱落防止材11は、移動片31及び係合片32からなる断面上下反転Ｌ字状金属片である。この脱落防止材11は、凸突起30,30間に嵌め込み、凸部材10へ水平方向に差し込んだ調整ネジ33に移動片31を螺合し、係合片32のみを凸突起30,30間から水平方向に突出可能にしている。
【００３１】
案内本体28は、コイルスプリング29の下端を係合する支持突起34を底面から切り起こし、凸部材10の昇降方向を規制する平行レール35,35と、凸部材10の逸脱を防止する拘束ピン36の差込孔37とを、それぞれ側面に一体成形している。
【００３２】
凸部材10は、コイルスプリング29を遊嵌状態で嵌め込むスプリング孔68を底面から上方に向けて穿孔し、側面には案内本体28の平行レール35,35に規制されるレール溝38を設けると共に、案内本体28の側面縁部を抱持するガイドフランジ39,39を設け(図７参照)、案内本体28の差込孔37から差し込んだ拘束ピン36を挿通させる上下方向の長孔からなる拘束溝40を貫設している。凸部材10は、案内本体28の平行レールにレール溝38が従うことで昇降方向が規制され、案内本体28から差し込んだ拘束ピン36を拘束溝40に挿通させることで昇降範囲が規制されている。
【００３３】
本発明の特徴は、軸孔20に旋回ピン８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８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８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８から突出する係止ピン27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。
【００３４】
戸板取付具１の案内部13は、ガイドレール９に凸部材10先端を一対の凸突起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、案内部13に対して各戸板２,３の向きが変化し、案内部13に従う旋回ピン８は戸板２,３に従う取付基部17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８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。
【００３５】
そこで、本例のキー溝19と係止ピン27とは、図10(a)に見られるように、通常旋回範囲外である135度(案内部13と戸板２,３との開度135度)の位置関係で一致させて、旋回ピン８を軸孔20に差し込むようにしている。これにより、戸板２,３の開閉操作に従う旋回ピン８の通常旋回範囲では、図10(b)及び図10(c)に見られるように、キー溝19と係止ピン27とが一致することはなく、抜け止めを図ることができる。
【００３６】
折戸４全体は固定側の戸板２の下端面７に取り付けた旋回受具15で軸支持しており、戸板取付具１は折戸４の開閉に際して傾倒し、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基部17への係止ピン27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。
【００３７】
戸板取付具１の取付を終えた各戸板２,３は折り畳んだ状態とし、開口部５下縁(本例では床面12)に載せた状態で戸板２,３を引き起こし、戸板２の下端面７を旋回受具15に軸支させておいてから案内部13をガイドレール９直下へ持ってくる。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10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11に見られるように、案内本体28に対して凸部材10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10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12参照)。
【００３８】
凸部材10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41に凸突起30以外の前後の部位を当接する。このため、従来のように戸板２の下端面７（旋回受具15）側での高さ調整を必要としない。固定側の戸板２側の凸部材10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14への嵌入によって左右位置も規制される。
【００３９】
こうして凸部材10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11を突出させる。
【００４０】
本例の場合、調整ネジ33は凸部材10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33を右に回すと相対的にガイドレール９の下縁フランジ41に向けて係合片32を突出させその上方に位置させることができる(図12中右方向)。凸部材10はガイドレール９の下縁フランジ41の先端に当接して位置規制されているため、係合片32を突出させた脱落防止材11の移動に関する自由度は低く、下縁フランジ41との重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10が抜け落ちて戸板２,３が外れる虞れがなくなる。
【００４１】
本発明の戸板取付具１は、戸板２,３の上端面６に対して旋回ピン８を枢着できればよく、取付部16として戸板２,３の上端面６に嵌合する取付基部は必須ではない。例えば、図13に見られるように、戸板２の上端面６から裏面にかけて側面視Ｌ字状片の取付補助部65を添設し、ピン基部18を短尺の旋回ピン66の螺合により前記取付補助部65の上端面側に軸着してもよい。
【００４２】
これにより、例えば中実な木製戸板に特別な加工を施さなくても本発明の戸板取付具１を取り付けることができるようになり、例えば木製戸板からなる開き戸の扉開閉装置(図13参照)を構成できるようになる。本例の取付補助部65は、木ネジ67を用いて戸板２,３に固着しているため、ネジ止め等を不要にして取付作業を容易にする上述の例(図１以下参照)の利点は失われるが、戸板側に取付基部を嵌合させるための加工を施したり軸孔を直接穿設したりせずに済むため、凸部材10をガイドレール９へ容易に嵌入する利点を、多様な戸板に提供できる別効果が得られる。
【００４３】
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、裏面側に位置する戸板取付具１の案内部13を、前記ガイドレール９に締着した固着補助具14に嵌入して拘束し、下端面を開口部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固定側の戸板２と全く同じ構造にすればよい。
【００４４】
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。
【００４５】
【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取付作業を容易にし、建物の開口部へ簡単に戸板を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からなる取付部の構成と、上方に向けて付勢して弾支した凸部材を設けた案内部の構成とに負う。特に、凸部材の構成は、ガイドレールに対する適当な嵌入量を実現し、従来見られた戸板下端面側における旋回受具や戸車での高さ調整を不要にする効果を有する。
【００４６】
具体的には、作業上の改善点として、皿ネジを必要とすることなく戸板に取り付けることができ、現場での取付作業を簡略化する。特に、ドライバーがなくても取付作業ができる利点がある。また、建物の開口部に戸板を取り付ける作業は、重い戸板を持ち上げる必要がなく、更にガイドレールに対して簡単かつ確実に凸部材を嵌入できるため、戸板を落下させるという危険性を招く虞れも解消する効果がある。
【００４７】
次に、構造上の改善点として、ガイドレールに対する凸部材の嵌入量の調整が不要となる利点がある。凸部材は、上方に付勢したことにより弾支した状態にあり、ガイドレールの高さに応じて自律的に嵌入量を調整できる。また、こうした凸部材を構成することで、戸板自体の高さ調整を戸板取付具で図ることができ、従来のように戸車に複雑な高さ調整手段を設けなくてよくなる効果をもたらす。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。

BACKGROUND OF THE INVENTION
The present invention, in the opening of the building is a partition such as a closet or room, mounting the door leaf of the folding door or hinged door openably door leaf mounting again and again relates.
[0002]
[Prior art]
In general, a door plate attachment for attaching a folding door or a hinged door to an opening of a building, such as a closet or a room partition, is attached to each door at a construction site in order to improve transportation and packing efficiency. For example, a door plate fitting (folding door metal fitting) found in Patent Document 1 is attached by fastening a vertical plate portion to a rear surface of the upper end portion of the folding door (door plate) and tightening with a countersunk screw screwed through an attachment hole. Also, when folding the folding door (door plate), fit the convex part (convex member) of the guide piece (door plate fixture) to the rail (guide rail fixed to the lower edge of the opening), then lift the folding door (door plate) Place the door wheel attached to the back of the lower end of the door.
[0003]
[Patent Document 1]
Japanese Patent No. 3312021 (pages 3-6, FIG. 9)
[0004]
[Problems to be solved by the invention]
The door plate fixture proposed by Patent Document 1 has some problems in work or structure. First, as a problem in the work, a large number of countersunk screws to be attached to the door plate are required, and it is troublesome as the above-mentioned on-site attachment work, and the attachment work cannot be performed without a driver. In addition, the work of attaching the door plate to the opening of the building imposes the labor of lifting the heavy door plate, and also points out that, for example, the convex member cannot be inserted well into the guide rail, leading to the risk of falling the door plate. .
[0005]
Next, as a structural problem, it can be mentioned that it is difficult to appropriately set the fitting amount of the convex member to the guide rail. As can be seen from the mounting operation of the door plate, it is desirable that the convex member of the door plate mounting tool can be deeply inserted into the guide rail at the time of installation, and after the installation, it is necessary and sufficiently engaged while being lowered to the guide rail. .
[0006]
However, the dimensional accuracy of the opening of the building is low, and the height of the guide rail fixed to the upper edge of the opening (kamoi) varies. As a result, the fitting amount of the convex member to the guide rail cannot be set appropriately. Moreover, such a relationship between the guide rail and the convex member leaves the possibility that the convex member will fit into the guide rail to the extent that the door pulley is detached, and has caused a risk that the door plate will come off. For this reason, there are not a few examples in which the height adjustment means is separately provided on the side of the door to the conventional door plate.
[0007]
Thus, the conventional door plate fixture has problems in work and structure, and improvement has been desired. Therefore, it was studied to develop a door plate fixture that can be easily attached to the door plate without the need for tools and can be easily attached to the opening of the building. In particular, the structure of the convex member inserted into the guide rail was examined, and the target board was studied to facilitate the mounting operation of the door plate and to easily realize an appropriate amount of insertion into the guide rail.
[0008]
[Means for Solving the Problems]
What was developed as a result of the study was a mounting part that pivotally attaches a swivel pin to the upper end surface of the door plate that can be freely opened and closed to the opening of the building, and a convex member that fits from below into the guide rail fixed to the upper edge of the opening of the building and Ri Do and a guide portion for pivoting said pivot pin axially on the back side of the door leaf, the guide portion door leaf fitting formed by elastically supported by biasing the convex member upwardly, the mounting portion, door panel The mounting base is integrally fitted to the upper end surface of the pin, and the pin base is provided with a pivot pin protruding therefrom. The mounting base has a key groove formed in a shaft hole drilled at a depth through which the pivot pin penetrates. The lock pin protrudes from the side of the swivel pin deeper than the shaft hole, and the keyway and the lock pin are aligned horizontally outside the normal swivel range of the swivel pin following the door opening / closing operation, and swivel into the shaft hole. This is a door plate fixture in a positional relationship that allows the pins to be freely inserted and removed . This is a door plate attachment for an outer set door in which the door plate upper end is arranged on the front side of the guide rail and the door plate is attached to the opening. This door plate attachment is hidden behind the door plate and is hardly visible from the front.
[0009]
The specific guide part is good to have a configuration in which the convex member is accommodated and elastically supported by energizing the convex member upward with respect to the guide body that regulates the elevation direction and the elevation range of the convex member.
[0010]
In the door plate attachment tool of the present invention, the guide portion is pivotally attached to the door plate via the turning pin of the attachment portion pivotally attached to the upper end surface of the door plate. Since the swivel pin is inserted into the upper end surface from the upper side to the lower side, it usually does not easily detach from the upper end surface. From this, this attachment part may be the structure which inserts a turning pin in the upper end surface simply so that turning is possible. This facilitates the attachment of the door plate attachment to the door plate. For example, only the shaft hole into which the swivel pin is inserted needs to be drilled in the door plate. However, in view of the mounting stability of the door plate mounting tool with respect to the door plate, it is preferable that the mounting portion is configured to insert the swivel pin into the upper end surface so as to be turnable in a state of being removed.
[0011]
Specifically, the mounting portion includes a mounting base portion that is integrally fitted to the upper end surface of the door plate, and a pin base portion that protrudes a pivot pin. The mounting base portion is keyed to a shaft hole that is drilled at a depth that allows the pivot pin to penetrate. A groove is engraved, the pin base protrudes from the side of the swivel pin deeper than the shaft hole, and the keyway and the lock pin are positioned horizontally outside the normal swivel range of the swivel pin according to the door opening / closing operation. Are arranged so that the pivot pin can be freely inserted into and removed from the shaft hole.
[0012]
The above mounting part can easily realize the shaft hole structure for inserting the swivel pin in the secured state by integrally fitting the mounting base with the shaft hole into which the swivel pin is inserted into the upper end surface of the door plate. Reduce the hassle of. The pivot pin provided with the locking pin can be prevented from coming off unless the key groove of the shaft hole matches the locking pin.
[0013]
Here, if the key groove and the locking pin are in a positional relationship that matches the outside of the normal turning range of the swiveling pin that follows the door plate opening / closing operation, the swiveling pin may be inadvertently detached from the shaft hole during normal use of the door plate. This can be prevented. When attaching the pin base to the mounting base, 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 in the positional relationship between the key groove and the locking pin as described above. The convenience of easily attaching the door plate attachment to the door plate is not impaired.
[0014]
Further, the door plate fixture of the present invention comprises a convex member that is provided integrally with the conventional fixture body (corresponding to the guide portion of the present invention) as a separate member from the guide portion, and is further attached upward with respect to the guide portion. I supported it. This means that the convex member can freely move in and out of the guide portion. Thereby, even if the convex member protrudes greatly from the guide portion, it is possible to ensure the lifting amount necessary for placing the door wheel on the guide rail fixed to the lower edge of the opening portion by immersing the convex member.
[0015]
In addition, when attaching the door plate to the opening, for example, a convex member that has been immersed by striking against a ridge can protrude autonomously by urging when it reaches the position directly below the guide rail, and can be inserted into this guide rail, or the amount of insertion into the guide rail can be reduced. Since it can adjust with the protrusion amount of the convex member from a guide part, the necessity of providing a height adjustment means in the doorwheel side like the past can be reduced or eliminated.
[0016]
The guide portion may be provided with a drop-off preventing material that protrudes and protrudes from the convex member fitted into the guide rail toward the inner wall of the guide rail. This guide part projects the drop-off prevention material toward the inner wall of the guide rail, thereby engaging the drop-off prevention material with the guide rail (more specifically, the lower edge flange of the guide rail). By restricting the degree of freedom of the convex member, it is possible to prevent the convex member from being inadvertently detached from the guide rail.
[0017]
A specific drop-off prevention material can be exemplified by a cross-sectional L-shaped plate material composed of a moving piece and an engaging piece. This drop-off prevention material is configured by screwing the moving piece onto an adjusting screw inserted into a convex member and projecting an engaging piece from the convex member in the horizontal direction.
[0018]
If the said door-plate attachment is used, a folding door or a hinged door can be comprised as follows. The folding door is a pair of folding door plates that are flexibly attached to the opening of the building, a guide rail fixed to the upper edge of the opening, and pivotally attached to the upper end surface of the outer edge of each door plate to the guide rail. In the door opening and closing device comprising the door plate fittings to be fitted, each door plate attachment member urges a convex member inserted from below into the guide rail and elastically supports the folding door at the opening of the building. It becomes the attached door opening and closing device.
[0019]
In addition, the hinged door is pivotally attached to one end of the upper end surface of the door plate and fitted to the guide rail for the door plate for the hinged door that can be freely opened and closed to the opening of the building, the guide rail fixed to the upper edge of the opening. In the door opening and closing device comprising a door plate fixture, each door plate fixture is a door with a hinged door attached to the opening of a building, wherein a convex member inserted from below into the guide rail is urged upward and elastically supported. It becomes a switchgear.

[0021]
As shown in FIGS. 1 to 4, the door opening and closing device of this example attaches an outer set type folding door 4 composed of fixed and moving door plates 2 and 3 connected in a bending relationship to an opening 5 of a building. It is a configuration. In this example, the guide rail 9 is provided only at the upper edge of the opening 5, and the lower end edge of the opening 5 remains the floor 12. As shown in FIG. 5, the fixed-side door plate 2 is fitted and restrained by inserting the guide portion 13 of the door-plate fixture 1 located on the back side into a fixing aid 14 fastened to the guide rail 9. The end face is pivotally supported by a swivel support 15 that is fixed to the lower end position of the opening 5 side edge so that only swivel is possible.
[0022]
As shown in FIG. 6, the door plate 3 on the moving side pivots while moving along the guide rail 9 by directly fitting the convex member 10 of the door plate fixture 1 attached to the upper end surface 6 into the guide rail 9. . In other words, the door opening and closing device of this example is supported by the swivel receiver 15 of the fixed door plate 2 as a whole and the door is swung in a state in which the tilting is prevented by the fixing auxiliary tool 14, and the door plate 3 on the moving side. The folding door 4 as a whole is opened and closed while being bent by the guide rail 9.
[0023]
As shown in FIGS. 7 to 9, the door plate mounting tool 1 includes a mounting portion 16 that pivotally attaches the pivot pin 8 to the upper end surface 6 of each door plate 2, 3, and a convex that fits into the guide rail 9 from below. It comprises a guide portion 13 that urges the member 10 upward and elastically supports it. The mounting portion 16 may be inserted into a shaft hole that is directly drilled in each door plate 2, 3, but it is difficult to prevent the pivot pin 8 from coming off from the shaft hole that is responsible for mounting the door plate fixture 1 to each door plate 2, 3. .
[0024]
Therefore, the mounting portion 16 of this example is composed of a mounting base portion 17 that is integrally fitted to the upper end surfaces of the corner portions of the door plates 2 and 3, and a flat-plate-shaped pin base portion 18 that protrudes the swivel pin 8. A shaft hole 20 having a keyway 19 is drilled in the mounting base 17.
[0025]
The mounting base portion 17 is a resin block body having a shaft hole 20 perforated with a depth through which the swivel pin 8 penetrates, and urethane resin is applied to the space in the door plate in a state of being attached to the upper end surfaces of the corner portions of the door plates 2 and 3 in advance. Injection foaming and adhesive integration. In addition, the engagement protrusion 24 in the insertion groove 23 that engages the notch 22 provided in the abutment rib 21 of the steel plate on the front side and the back side in the door plate is intended to reliably prevent the upper end surface 6 from coming off. Yes.
[0026]
Although not shown in the drawing, a more reliable prevention is provided if the projecting piece that sinks into the lower surface side of the mold material (see FIG. 9) that closes the upper end surface 6 protrudes from the side surface of the adjacent mounting base 17 and is pressed down. Figured. The shaft hole 20 has a pair of key grooves 19 and 19 formed at point-symmetric positions, and a metal retaining plate 26 provided with an insertion hole 25 having the same shape as the section of the shaft hole 20 at the lower end of the shaft hole 20. Is inserted.
[0027]
Compared to the resin mounting base 17, the metal retaining plate 26 is worn by friction between the engaging pivot pin 8 and the retaining pin 27, or by the retaining pin 27 when a pulling load is applied to the pivot pin 8. There is no breakage, and the engagement with the locking pin 27 can be kept stable.
[0028]
The pin base 18 is a foundation that hangs the swivel pin 8 on a plate surface that extends forward from the guide body 28 of the guide portion 13 toward the door plate and is bent horizontally. The swivel pin 8 penetrates the locking pin 27 at a position deeper than the shaft hole 20 drilled in the mounting base 17 (more precisely, a position deeper than the total thickness of the shaft hole 20 and the metal retaining plate 26), and is engaged from the side. Both ends of the stop pin 27 are projected. In the door plate fixture 1, the pin base portion 18 and the guide portion 13 are integrally turned from the turning pin 8 relative to the attachment base portion 17 fitted to the upper end surface 6 of each door plate 2 and the three corners.
[0029]
The guide portion 13 includes an outer box-shaped metal guide body 28 that extends the pin base portion 18 made of the plate material, and a convex member 10 of a resin block that is fitted to the guide body 28 so as to be movable up and down. A coil spring 29 that repels upward is interposed between 28 and the convex member 10, and is elastically supported by urging the convex member 10 upward. In the present example, the entire upper surface is integrally formed with a pair of convex protrusions 30, 30 that fit into the guide rail 9.
[0030]
The drop-off prevention material 11 is an L-shaped metal piece that is vertically inverted in cross section and includes a moving piece 31 and an engaging piece 32. The drop-off prevention material 11 is fitted between the convex protrusions 30 and 30, and the moving piece 31 is screwed onto the adjustment screw 33 inserted in the horizontal direction into the convex member 10, and only the engaging piece 32 is inserted between the convex protrusions 30 and 30. Protrusible in the horizontal direction.
[0031]
The guide body 28 cuts and raises the support protrusion 34 that engages the lower end of the coil spring 29 from the bottom surface, the parallel rails 35 and 35 that restrict the elevation direction of the convex member 10, and the restraining pin 36 that prevents the convex member 10 from deviating. The insertion holes 37 are integrally formed on the side surfaces.
[0032]
The convex member 10 has a spring hole 68 into which the coil spring 29 is fitted in a loosely fitting state, and is drilled upward from the bottom surface, and a rail groove 38 that is regulated by the parallel rails 35 and 35 of the guide body 28 is provided on the side surface. Guide flanges 39 and 39 for holding the side edges of the guide body 28 are provided (see FIG. 7), and a restraint consisting of a vertically long slot through which the restraint pin 36 inserted from the insertion hole 37 of the guide body 28 is inserted. A groove 40 is provided. As for the convex member 10, the raising / lowering direction is restricted by the rail groove 38 following the parallel rail of the guide body 28, and the raising / lowering range is restricted by inserting the restriction pin 36 inserted from the guide body 28 into the restriction groove 40. .
[0033]
The feature of the present invention lies in that the door plate mounting tool 1 can be attached to the upper end surfaces 6 of the door plates 2 and 3 simply by inserting the swivel pin 8 into the shaft hole 20 in a state of being removed. For this reason, the pivot pin 8 can be freely inserted into and removed from the shaft hole 20 during mounting, and the pivot pin 8 needs to be in a state of being prevented from being removed from the shaft hole 20 when a normal door opening / closing device is used. Specifically, the positional relationship between the key groove 19 carved in the shaft hole 20 and the locking pin 27 protruding from the swivel pin 8 in the horizontal plane is specified, and the selection of attachment and removal is realized.
[0034]
The guide portion 13 of the door plate fixture 1 is fixed to the guide rail 9 in the direction of the guide rail 9 because the tip of the convex member 10 is inserted into the guide rail 9 by the pair of convex protrusions 30 and 30 so as not to rotate. For this reason, when each door plate 2, 3 is folded by opening / closing operation of the folding door 4, the direction of each door plate 2, 3 changes with respect to the guide portion 13, and the swivel pin 8 following the guide portion 13 is attached to the base plate according to the door plate 2, 3. It turns with respect to 17 shaft holes 20. The normal turning range with respect to the shaft hole 20 of the turning pin 8 following the opening and closing operation of the door plates 2 and 3 is approximately 0 degrees (the closed state in which the door plates 2 and 3 are arranged in a straight line) from the change in the direction of the door plates 2 and 3. It is 90 degrees (open state in which each door plate 2 and 3 is folded).
[0035]
Therefore, as shown in FIG. 10 (a), the keyway 19 and the locking pin 27 in this example are 135 degrees outside the normal turning range (the opening degree between the guide portion 13 and the door plates 2 and 3 is 135 degrees). ) So that the swivel pin 8 is inserted into the shaft hole 20. As a result, in the normal turning range of the turning pin 8 according to the opening / closing operation of the door plates 2 and 3, the key groove 19 and the locking pin 27 should coincide with each other as seen in FIGS. 10 (b) and 10 (c). There is no, and it can aim at retaining.
[0036]
The whole folding door 4 is axially supported by a swivel receiver 15 attached to the lower end surface 7 of the stationary door plate 2, and the door plate attachment tool 1 is tilted when the folding door 4 is opened and closed so as not to deviate from the opening 5. Therefore, there is no problem in the mounting strength of the door plate fixture 1 with respect to the door plates 2 and 3 even if the locking pin 27 is merely engaged with the mounting base 17 at a position disengaged from the keyway 19.
[0037]
The door plates 2 and 3 that have been attached to the door plate fixture 1 are folded, and the door plates 2 and 3 are raised in the state of being placed on the lower edge of the opening 5 (the floor surface 12 in this example). After 7 is pivotally supported on the swivel support 15, the guide portion 13 is brought directly below the guide rail 9. Here, the convex member 10 that is elastically biased upward by the coil spring 29 causes the convex protrusions 30 and 30 to protrude normally and cannot be fitted into the guide rail 9 as it is, but as shown in FIG. By pushing down the convex member 10 against the guide body 28 by the operator's hand, the convex protrusions 30 and 30 are brought to just below the guide rail 9, and the load that has pushed the convex protrusions 30 and 30 down is removed. The convex member 10 returns autonomously and the convex protrusions 30 and 30 can be fitted into the guide rail 9 (see FIG. 12).
[0038]
The convex member 10 is biased upward by the bias of the coil spring 29, and the front and rear portions other than the convex protrusions 30 are brought into contact with the lower edge flange 41 of the guide rail 9. For this reason, the height adjustment by the side of the lower end surface 7 (swivel receiving tool 15) of the doorplate 2 is not required unlike the past. As is apparent from FIG. 5, the right and left positions of the convex member 10 on the fixed side door plate 2 are also restricted by the insertion of the protrusions 30 and 30 into the guide rail 9 and the insertion of the fixing aid 14.
[0039]
If the convex protrusions 30 and 30 of the convex member 10 can be fitted into the guide rail 9 in this way, the attachment of the door plates 2 and 3 to the opening 5 is completed. In the present invention, in order to further secure the mounting stability of the door plates 2, 3, the drop-off prevention material 11 is protruded from the protruding protrusions 30, 30 fitted in the guide rail 9 toward the catches provided in the guide rail 9.
[0040]
In this example, since the adjustment screw 33 is only inserted in a fixed position with respect to the convex member 10, the adjustment screw 33 is engaged toward the lower edge flange 41 of the guide rail 9 when the adjustment screw 33 is turned to the right. The piece 32 can be projected and positioned above (right direction in FIG. 12). Since the position of the convex member 10 is restricted by coming into contact with the tip of the lower edge flange 41 of the guide rail 9, the degree of freedom with respect to the movement of the drop-off prevention material 11 with the engaging piece 32 protruding is low. Since the overlapping relationship is not released, there is no possibility that the convex member 10 will fall out of the guide rail 9 and the door plates 2 and 3 will come off in normal use.
[0041]
The door plate fixture 1 of the present invention only needs to be able to pivotally attach the swivel pin 8 to the upper end surface 6 of the door plates 2 and 3, and the mounting base that fits the upper end surface 6 of the door plates 2 and 3 is not essential as the attachment portion 16. Absent. For example, as shown in FIG. 13, an attachment auxiliary portion 65 of an L-shaped piece in side view is attached from the upper end surface 6 to the back surface of the door plate 2, and the pin base 18 is attached by screwing a short swivel pin 66. You may axially attach to the upper end surface side of the auxiliary | assistant part 65. FIG.
[0042]
Thereby, for example, the door plate fixture 1 of the present invention can be attached without applying special processing to a solid wooden door plate. For example, a door opening / closing device (see FIG. 13) for a hinged door made of a wooden door plate is provided. Can be configured. Since the mounting auxiliary portion 65 of this example is fixed to the door plates 2 and 3 using wood screws 67, the advantage of the above-described example (see FIG. 1 and subsequent drawings) that facilitates the mounting work by eliminating the need for screwing or the like. However, there is no need to perform a process for fitting the mounting base on the door plate side or to directly drill the shaft hole. Therefore, there are various advantages of easily fitting the convex member 10 into the guide rail 9. Another effect that can be provided to a large doorboard.
[0043]
In order to configure the door opening / closing device of the hinged door, the door plate fixture 1 having the same structure as that of the above-described example (see FIG. 1 and the subsequent drawings) is pivotally attached to the side end portion of the door plate 2 on the upper end face 6 side. As shown in FIG. 5, the door plate 2 is fitted and restrained by inserting the guide portion 13 of the door plate fixture 1 located on the back surface side into the fixing aid 14 fastened to the guide rail 9 and opening the lower end surface. It is pivotally supported by a swivel support 15 that is fixed to the lower end position of the side edge of the part 5 so that it can turn. That is, the same structure as the door plate 2 on the fixed side in the example of the door opening / closing device of the folding door described above may be used.
[0044]
This means that the members can be shared without any difference between the folding door and the hinged door. As a result, the product cost can be reduced, and it is possible to greatly reduce the labor of member management and installation when installing folding doors and hinged doors in the same building.
[0045]
【The invention's effect】
According to the present invention, it is possible to provide a door plate mounting tool that can be easily attached to the opening of a building and can be easily attached to an opening of a building so that a tool is not required when mounting to the door plate. This is due to the structure of the mounting part consisting of a turning pin that can be inserted into and removed from the door hole on the door plate side only outside the normal turning range, and the structure of the guide part provided with a convex member that is urged and supported upward. Bear. In particular, the configuration of the convex member has an effect of realizing an appropriate amount of insertion with respect to the guide rail and making it unnecessary to adjust the height of the swivel support or the door wheel on the lower end face side of the door plate that has been conventionally seen.
[0046]
Specifically, as an improvement in work, it can be attached to a door plate without the need for a countersunk screw, thereby simplifying the installation work on site. In particular, there is an advantage that the mounting operation can be performed without a driver. In addition, the work of attaching the door plate to the opening of the building does not require lifting the heavy door plate, and furthermore, since the convex member can be easily and reliably inserted into the guide rail, there is a risk that the door plate may be dropped. There is an effect to cancel.
[0047]
Next, as a structural improvement, there is an advantage that it is not necessary to adjust the insertion amount of the convex member with respect to the guide rail. The convex member is in a state of being elastically supported by being biased upward, and the insertion amount can be adjusted autonomously according to the height of the guide rail. Moreover, by constructing such a convex member, the height of the door plate itself can be adjusted by the door plate fixture, which brings about an effect that it is not necessary to provide a complicated height adjusting means in the door wheel as in the prior art. As described above, the door plate fixture of the present invention has an effect of improving work and structure.
