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、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。

【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。

BACKGROUND OF THE INVENTION
The present invention relates to a door plate attachment for attaching a folding door or a door of a hinged door to an opening of a building such as a closet or a partition of a room so as to be opened and closed.
[0002]
[Prior art]
Door plate fittings that can be attached to the opening of a building, such as closets and room dividers, so that the doors of folding doors or hinged doors can be freely opened and closed are provided in the holes provided in the door plates in the door plate production process in order to ensure the attachment to the door plates. It is common to install by hammering in. For example, a door plate fixture (support) found in Patent Document 1 is an upper rail (a guide rail fixed to the upper edge of an opening) by a plastic-molded cylindrical case (attachment portion) incorporating a spring therein. A roller (convex member) fitted into the shaft (swivel pin) mounted on the upper end is urged upward to support it so that it can move forward and backward, and this case (mounting part) is driven into and fixed to the door panel (door plate). Install.
[0003]
[Patent Document 1]
JP-A-8-277675 (pages 3 to 4, FIG. 1)
[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 work, it can be mentioned that it requires a hammering operation with a hammer, it is difficult to adjust the force when driving, and there is a possibility of breaking the parts. Moreover, although it fixes using an adhesive agent in order to ensure the attachment to a doorplate, the storage management and handling of an adhesive agent are not easy, and the point which worsens a working environment can also be pointed out.
[0005]
Next, as a structural problem, it can be mentioned that a part of the convex member and the swivel pin protrudes from the door plate to reduce transportation and packing efficiency. In addition, it can be pointed out that there is a possibility that the protruding member protruding during transportation may be damaged by impact.
[0006]
Thus, the conventional door plate fixture has problems in work and structure, and improvement has been desired. Therefore, the installation to the doorboard was studied in order to develop a doorboard fixture that can be easily and reliably attached to each doorboard at the construction site, making hammering and adhesive unnecessary and making it easy.
[0007]
[Means for Solving the Problems]
What was developed as a result of the study was that the mounting part that was attached to the upper end surface of the door plate that could be freely opened and closed to the opening of the building and the swivel pin that protruded downward from the lower surface were pivotally attached to the mounting part. In a door plate fixture comprising a convex member fitted from below into a guide rail fixed to the upper edge of the opening of the door, the mounting portion has a key groove formed in a shaft hole drilled at a depth through which the pivot pin penetrates, and the pivot pin The locking pin protrudes from the side surface deeper than the shaft hole, and the keyway and the locking pin are aligned in the horizontal position outside the normal turning range of the turning pin according to the door opening / closing operation, and the turning pin is removed from the shaft hole. It is a door plate mounting tool characterized by having a positional relationship that can be freely changed.
[0008]
In the door plate attachment tool of the present invention, the convex member is attached to the door plate so as to be rotatable via a turning pin pivotally attached to an attachment portion attached integrally to the upper end surface of the door plate. The convex member is inserted from the lower side into the guide rail fixed to the upper edge of the opening of the building with the swivel pin inserted into the mounting portion from the upper side to the lower side, so that it can be easily detached from the upper end surface of the door plate. There is no.
[0009]
The mounting part has a structure in which a key groove is engraved in a shaft hole drilled at a depth that penetrates the swivel pin in advance. 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 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. Can be prevented. When attaching the door plate attachment to the door plate, there is no restriction on the turning range of the turning pin, so it is easy to insert the turning pin into the shaft hole even in the positional relationship of 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.
[0011]
The convex member is formed by projecting a pair of convex protrusions upward from the upper surface, and by inserting both convex protrusions into the guide rail at the same time, each convex protrusion regulates the rotation with respect to each other so that the protruding direction of the convex rail Is a uniquely defined configuration. In addition, the convex member is provided with a drop-off prevention material that moves forward and backward in the horizontal direction from the insertion portion into the guide rail, and the drop-out prevention material is advanced in a state where the insertion portion is fitted into the guide rail. It is preferable that the convex 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 convex member has a pair of convex projections that project into the guide rail from the upper surface upward, and the drop-off prevention material is horizontally disposed between the pair of convex projections. It is good to move forward and backward. The drop-off prevention material is an L-shaped cross-section plate member made up of a moving piece and an engaging piece. The moving piece is screwed into an adjusting screw inserted into the protruding member, and the engaging piece protrudes horizontally from the protruding member. This structure can be exemplified.
[0013]
Further, the convex member may be provided with an elastic support member interposed between the lower surface and the mounting portion, and may be elastically urged upward with respect to the upper end surface of the door plate by the restoring force of the elastic support member. An example of the elastic support member is a coil spring. When the coil spring is loosely fitted to a pivot pin protruding 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]

As shown in FIG. 3, the convex member 8 positioned coaxially with the swivel pin 10 simultaneously inserts the convex protrusions 30 and 30 into the guide rail 9, and the convex protrusions 30 and 30 regulate the rotation with respect to each other. The insertion direction of the convex member 8 with respect to the rail 9 is uniquely determined with respect to the guide rail 9. Thereby, the door plate 3 on the moving side turns around the turning pin 10 while moving along the guide rail 9.
[0018]
Thus, the door opening and closing device of this example opens and closes while the stationary and moving door plates 2 and 3 are bent with the guide rail 9 prevented from being tilted, and the folding door 4 as a whole turns the stationary door plate 2. The structure is supported by the support 15.
[0019]
As shown in FIGS. 1 to 3, the door plate fixture 1 for the inner set type folding door 4 of the present example is provided with a blindfold 16 so that the guide rail 9 and the convex member 8 are almost hidden by the flange 16. be able to. As shown in FIG. 6, the door plate attachment 1 is pivotally attached to the upper end surface 6 of each door plate 2 and 3 and the attachment portion 18 that is integrally fitted to the upper end surface of the corner portion of each door plate 2 and 3. The swivel pin 10 that protrudes downward from the lower surface and the convex member 8 that has a pair of convex protrusions 30 and 30 protrude upward from the upper surface.
[0020]
The mounting portion 18 in this example is a resin block body having a shaft hole 20 drilled at a depth through which the swivel pin 10 penetrates, and engages with a notch 22 provided in a steel plate butt rib 21 in the door plates 2 and 3. The engagement protrusion 25 in the insertion groove 24 is designed to prevent the upper end surface 6 from coming off. Although not shown in the drawing, a more reliable prevention is provided if the projecting piece that sinks into the lower surface of the mold material (see FIG. 9) that closes the upper end surface 6 is projected from the side surface of the adjacent mounting portion 18 and pressed. Figured.
[0021]
The shaft hole 20 has a pair of key grooves 19, 19 at a point-symmetrical position, and a metal retaining plate 27 provided with an insertion hole 26 having the same shape as the section of the shaft hole 20 at the lower end of the shaft hole 20. Is inserted. Further, a recess 23 is formed on the upper surface for securing a lowering margin of the convex member 8 that moves up and down integrally with the pivot pin 10.
[0022]
The metal retaining plate 27 is not worn by rubbing of the pivot pin 10 with the latch pin 28 and is not damaged by the latch pin 28 when a pulling load is applied to the pivot pin 10. Engagement can be kept stable. Actually, since the swivel pin 10 is always pressed downward by the convex member 8 fitted in the guide rail 9, there is little chance that the locking pin 28 rubs against the metal retaining plate 27 (in FIG. (See the gap between the retaining plate 27 and the locking pin 28).
[0023]
The convex member 8 is formed of a resin block having a substantially rectangular parallelepiped shape in which the swivel pin 10 is suspended downward from the lower surface and the convex protrusions 30 and 30 are projected upward from the upper surface.
[0024]
The swivel pin 10 penetrates the locking pin 28 at a position deeper than the shaft hole 20 drilled in the mounting portion 18 (precisely, a position deeper than the total thickness of the shaft hole 20 and the metal retaining plate 27), and is engaged from the side. Both ends of the stop pin 28 are projected. In this example, a coil spring 29 loosely fitted to the swivel pin 10 is interposed between the recess 23 of the mounting portion 18 so that the entire convex member 8 is elastically supported in an upward biased state.
[0025]
The pivot pin 10 may be inserted into a shaft hole directly drilled in each door plate 2, 3, but it is difficult to prevent the pivot pin 10 from being removed from the shaft hole that bears the door plate fixture 1 attached to each door plate 2, 3. . Therefore, by making a shaft hole 20 having a key groove 19 in a mounting portion 18 that is integrally fitted to the upper end surface of the corners of each door plate 2, 3, the key groove 19, can be easily formed on the upper end surface of the door plate 2, 3. A shaft hole 20 with 19 can be provided.
[0026]
In the convex member 8 of this example, the convex protrusions 30, 30 provided on the upper surface are simultaneously inserted into the guide rail 9, whereby the convex protrusions 30, 30 regulate the turning of each other, thereby uniquely defining the insertion direction with respect to the guide rail 9. It is fixed.
[0027]
The pair of convex protrusions 30, 30 that fit into the guide rail 9 are integrally formed on the upper surface of the convex member 8, and move up and down together with the convex member 8. The drop-off prevention member 31 is an L-shaped metal piece made up of a moving piece 32 and an engaging piece 33. The moving piece is screwed into an adjustment screw 34 inserted horizontally into the convex member 8 so that the engaging piece 33 is convex. It is possible to protrude horizontally between the protrusions 30 and 30.
[0028]
In the door plate attachment 1, the turning pin 10 and the convex member 8 are integrally turned with respect to the attachment portion 18 fitted to the upper end surface 6 of each door plate 2, 3. Further, since the elevating orbit of the convex member 8 is regulated by the turning pin 10 inserted into the shaft hole 20, the entire structure is simple.
[0029]
A feature of the present invention resides 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 10 into the shaft hole 20 in a state of being removed. For this reason, when mounting, the swivel pin 10 can be freely inserted into and removed from the shaft hole 20, and the swivel pin 10 needs to be in a state of being removed from the shaft hole 20 when a normal door opening / closing device is used. Specifically, the positional relationship in the horizontal plane between the key groove 19 engraved in the shaft hole 20 and the locking pin 28 protruding from the swivel pin 10 is specified, and the selection of attachment and removal is realized.
[0030]
Since the convex member 8 of the door plate fixture 1 is fitted into the guide rail 9 by the pair of convex protrusions 30 and 30 so as not to rotate, the direction is fixed to the guide rail 9. For this reason, when each door plate 2, 3 is folded by the opening / 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 swivel pin 10 according to the convex member 8 is attached to the door plate 2, 3. It turns with respect to 18 shaft holes 20. The normal turning range with respect to the shaft hole 20 of the turning pin 10 according to 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).
[0031]
Therefore, the key groove 19 and the locking pin 28 in this example coincide with each other in the positional relationship of 135 degrees (the opening degree of the convex member 8 and the door plates 2 and 3 is 135 degrees) outside the normal turning range, and the shaft hole 20 On the other hand, 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 operation of the door plates 2 and 3, as shown in FIGS. 7 (a) and 7 (b), the key groove 19 and the locking pin 28 does not match and can be secured.
[0032]
The folding door 4 as a whole has a support pin 13 projecting from the lower end surface 7 of the stationary door plate 2 pivotally supported by a swivel receiver 15 fixed to the lower edge of the opening 5. The door plate 2, 3 is tilted when opening and closing, and the main function is to prevent it from deviating from the opening 5, so that only the locking pin 28 is engaged with the mounting portion 18 at a position disengaged from the keyway 19. However, there is no problem in the mounting strength of the door plate fixture 1 to the door plates 2 and 3.
[0033]
Each of the door plates 2 and 3 having finished the attachment of the door plate fixture 1 first supports the support pin 13 of the lower end surface 7 on the swivel support 15 on the lower edge of the opening 5, and then the convex protrusion 30 of the convex member 8. It is possible to assemble 30 with respect to the opening 5 only by causing 30 to be fitted toward the guide rail 9. The convex member 8 urged upward by the coil spring 29 and supported by the coil spring 29 is lowered by pressing the coil spring 29 downward so as to compress it, as shown in FIG. It can be brought directly under the guide rail 9.
[0034]
Here, the convex member 8 urged upward by the coil spring 29 and elastically supported projects the convex protrusions 30 and 30 as normal, and cannot be fitted into the guide rail 9 as it is, but as shown in FIG. By pushing down the convex member 8 by the operator's hand, the convex protrusions 30 and 30 are brought to just below the guide rail 9, and the convex member 8 is autonomously removed by removing the load that pushed the convex protrusions 30 and 30 as they are. Then, the protrusions 30 and 30 can be fitted into the guide rail 9 (see FIG. 9).
[0035]
The convex member 8 is biased upward by the bias of the coil spring 29, and the front and rear portions other than the convex protrusion 30 are brought into contact with the lower edge flange 35 of the guide rail 9. For this reason, it is not necessary to adjust the insertion amount of the convex member 8 with respect to the guide rail 9 by adjusting the height of the door plate 2 on the lower end surface 7 (swivel receiver 15) side. As is clear from FIG. 5, the right and left positions of the convex member 8 on the stationary door plate 2 side are also regulated by the insertion of the protrusions 30 and 30 into the guide rail 9 and the insertion of the fixing aid 17. It should be noted that the description of the fixing aid 17 is omitted only in FIG.
[0036]
If the convex protrusions 30 and 30 of the convex member 8 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 member 31 is protruded from the protrusions 30, 30 fitted in the guide rail 9 toward the catches provided in the guide rail 9.
[0037]
In this example, since the adjustment screw 34 is only inserted in a fixed position with respect to the convex member 8, when the adjustment screw 34 is turned to the right, the fall-off prevention material 31 screwed into the adjustment screw 34 moves relatively. Then, the engaging piece 33 can be protruded from the protrusions 30 and 30 toward the lower edge flange 35 of the guide rail 9 and positioned above the lower edge flange 35 (rightward in FIG. 9).
[0038]
Since the convex member 8 abuts on the front end of the lower edge flange 35 of the guide rail 9 and is regulated in the front-rear direction, the degree of freedom with respect to the movement of the drop-off prevention material 31 with the engaging piece 33 protruding is low. Since the engagement relationship with the flange 35 is not released, there is no possibility that the convex member 8 falls off from the guide rail 9 and the door plates 2 and 3 come off in normal use.
[0039]
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 inserted into and restrained by a fixing auxiliary tool 17 fastened to the guide rail 9, and the support pin 13 protruding from the lower end surface is fixed. Is pivotally supported by a swivel receiver 15 that is fixed to the lower end position on the side of the opening 5 so that the swivel is possible. That is, the moving side door plate 3 in the example of the door opening / closing device of the folding door described above is eliminated, and only the stationary side door plate 2 is configured, and the stationary side door plate 2 has the same structure as the example of the door opening / closing device of the folding door described above. do it.
[0040]
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.
[0041]
【The invention's effect】
According to the present invention, it is possible to provide a door plate fixture that can be easily attached to a door plate at a construction site so that the attachment work can be facilitated to the extent that a tool is not required when attaching to the door plate. This is an effect obtained by the configuration of the pivot pin and the mounting portion that can be inserted into and removed from the shaft hole on the door plate side only outside the normal pivot range.
[0042]
As a work improvement point, the door plate attachment tool of the present invention can be attached to the door plate without requiring a hammering operation, and can be attached at a construction site. In particular, there is an advantage that the mounting operation can be performed without using an adhesive that is difficult to handle and store and deteriorates the working environment.
[0043]
As a structural improvement, the door plate fixture of the present invention has an advantage that the convex member and the pivot pin do not protrude from the door plate during transportation. Since the convex member and the pivot pin are attached at the construction site, the transportation and packing efficiency can be improved. Further, it is not necessary to worry about the door plate fixture being damaged during transportation as in the prior art. As described above, the door plate fixture of the present invention has an effect of improving work and structure.
