Description

【０００１】
【発明の属する技術分野】
本発明は、家具または通路等の左右に取り付けられた両開き扉の引き手の技術に係わり、更に詳しくは、両開き扉のめし合わせ部に該めし合わせ部のほぼ全域を覆う垂直の引き手とその引き手を引く操作に連動して作動するラッチ機構とを備え、高さ方向の任意の位置に手を掛けて操作でき且つ左右いずれの手でも容易に操作可能な引き手の構造に関する。
【０００２】
【従来の技術】
従来の両開き扉を備えた収納庫の引き手は、左右の各扉のめし合わせ部近傍に左扉には左手で操作する引き手と右扉には右手で操作する引き手をそれぞれ設けている。このような収納庫では、片手が不自由な人が利き手と反対側の扉の開閉操作する場合、手のひらを左右反対側に向けて引き手に手を掛ける必要がある。また、両開き扉を備えた収納庫を上段に積み重ねて設置した場合で低い身長の人がこの収納庫の扉を開閉操作する場合、困難を伴う場合がある。
【０００３】
一方、例えば、横長の引き出し式収納庫の上段に両開き扉を備えた収納庫を積み重ねる場合で、該引き出し式収納庫の引き出しの引き手が、本願出願人が開発した、引き出しの前板中央に引き出しの上下端部近傍に亘る垂直の引き手を設けるとともに、この各引き出しの引き手が垂直に一直線に連なり且つ左右いずれからも手を掛けて引き出しを片手で引き出すことができる形態とした収納庫である場合に、この下段収納庫の引き手と上段収納庫の引き手が異なる形態となり、外観的にアンバランスで違和感が感じられる。そのような場合には、上段の両開き式扉を備えた収納庫の引き手を、下段収納庫の引き手にとともに中央に垂直の一直線に連なる形態にすると統一された意匠的美観が創出される。この場合、引き手には引き手を引く操作に連動して扉上下に設けたラッチ機構の係合が解除される機能を備える必要がある。
【０００４】
【発明が解決しようとする課題】
前述の状況に鑑み本発明が解決しようとするところは、家具または通路等に設ける両開き扉の引き手を、扉のめし合わせ部のほぼ全体を覆って意匠的美観が創出される垂直の引き手とするとともに、人の身長や扉の高さに応じ適宜の高さに手を掛けて操作でき、左右いずれの手でも容易に開閉操作が行え、且つ引き手に手を掛ける位置に無関係に上下にラッチ機構を確実に連動操作する、全く新しい形態の引き手機構を提供することにある。本発明が解決しようとする他の課題は、上記の引き手とラッチ機構とを備えた側の扉の引き手が他方の扉の開放を規制する構造にして簡単に組み立てられ且つ製作コストを低減させること、更に他の課題は、上記垂直の引き手が、手を掛ける位置に無関係に扉上下のラッチ機構が互いに同期作動する引き手機構を提供することにある。
【０００５】
【課題を解決するための手段】
前述の課題解決のため、本発明の両開き扉の引き手機構は、枠体に左右側端を回動可能に支持された両開き扉の、一方の扉のめし合わせ部寄りの上下端近傍にそれぞれ中間部を回転可能に支持された水平の１対の引き手レバーと、前記めし合わせ部の前方に位置し且つ扉前面との間に隙間を隔てて前記上下引き手レバーの先端同士を連結する垂直の引き手と、該引き手が取り付けられた扉の内部または裏面側に設けられて扉開操作時の前記引き手レバーの回動に連動して前記扉と前記枠体とのロック状態が解除されるラッチ機構と、該ラッチ機構をラッチ爪係合方向に付勢する付勢手段とを備え、前記両開き扉の前面の引き手が位置する部分を、上下端近傍に亘ってそれぞれ後方傾斜させて後退部を形成し、引き手の後端側の一部が前記後退部に没する形態にして引き手を取り付けた構成とする。
【０００６】
なお、上記の引き手は、上下端部を除く中間部を、水平断面が前端を底辺とする略２等辺三角形になるように形成するとともに、該引き手の上下端を引き手レバーの先端にそれぞれ固着すると都合がよい。
【０００７】
上記の構成にすることにより、両開き扉の引き手は、扉のめし合わせ部のほぼ全体を覆って意匠的美観が創出されるとともに、人の身長や扉の高さに応じ適宜の高さに手を掛けて操作でき、左右いずれの手でも容易に開閉操作が行える引き手機構となる。
【０００８】
また、前記引き手の上下端部には、前記ラッチ機構が扉を枠体にロックした状態において、両側の扉の前面または前記後退部の前面にそれぞれ当接する端面を設けると好都合である。これにより、他方の扉が一方の扉の引き手で開放規制されるので、機構が簡単で且つ部品点数が少なく組立が簡単になり、製作コストが低減できるとともに、意匠的美観が創出される。
【０００９】
更に、前記ラッチ機構を、引き手レバーの支点近傍の扉内部または裏面側に回転可能に支持された垂直の軸と、該軸の両端近傍に固定されて先端部が前記引き手レバーの後端部に当接する１対の従動レバーと、前記軸の両端に固定された１対のラッチ爪と、扉を支持する前記枠体の上下の前端部にそれぞれ形成された前記ラッチ爪が係合する１対のラッチ受け部と、前記軸の中間部に設けられ一端を扉に他端を軸にそれぞれ係止した付勢バネとで構成され、該付勢バネにより前記ラッチ爪を前記ラッチ受け部に対し係合方向に付勢して構成すると好都合である。これらにより、引き手に手を掛ける高さ方向の位置に無関係に、扉上下のラッチ機構が互いに確実に同期作動する様になり、且つ、上下ラッチ機構の付勢力が上下均等に作用して作動を安定させることができる。
【００１０】
【発明の実施の形態】
つぎに本発明の実施の形態を添付図面に基づき詳細に説明するが、本発明は、添付図面に示された形態に限定されず特許請求の範囲に記載の要件を満たす実施形態の全てを含むものである。添付図は両開き扉を備えた収納庫の引き手機構を例示しているが、収納庫に限らず両開き扉を備えた家具や建物の通路や出入口の壁や扉枠に取り付けた両開き扉の引き手機構も本発明の技術範囲に含む。図１は、本発明に係る両開き扉の引き手機構を備えた両開き扉付きの収納庫の全体斜視図を示す。図２〜図５は、本発明に係る両開き扉の引き手機構の実施例の上端側を示す部分図で、図２は側面から見た状態で図３のＢ−Ｂ矢線に沿う断面、また図３は上方から見た状態で図２のＡ−Ａ矢線に沿う断面、図４は正面から見た状態で図２の左方から見た図、図５は各構成部材を展開した斜視図をそれぞれ示している。そして図６には、図１に示す収納庫、およびその扉に備えた引き手と同形態の引き手を備えた引き出し式収納庫を、上下に積み重ねた際の外観を参考に示す。
【００１１】
図において、両開き扉付き収納庫（以下、「収納庫」という）１は、直方体の収納庫１の筐体１ａの左右框部１ｂの前端部に蝶番部材（図示しない）でそれぞれ回動可能に取り付けられた両開き扉２，２ａを有する。本発明に係る引き手機構５においては、扉の引き手６は、該収納庫１の扉２，２ａのめし合わせ部２ｄを上下端に亘るほぼ全体を覆うようにしていずれか片方の扉、例えば図１における右側の扉２に設ける。
【００１２】
引き手機構５は、収納庫１の片方の扉２のめし合わせ部２ｄ寄りの上下端近傍に、それぞれ中間部をピン１１で回転可能に支持された水平の１対の引き手レバー８，８と、めし合わせ部２ｄの前方に位置し且つ扉２の前面との間に隙間を隔てて引き手レバー８，８の先端同士を連結する垂直の引き手６とを有するとともに、扉２の裏面側には、引き手６の回動に連動するラッチ機構と、該ラッチ機構をラッチ係合方向に付勢する付勢手段とを備えた構成からなる。なお、引き手レバー８，８は、扉２の裏面のめし合わせ部近傍の上下端に取り付けた１対の引き手支持部材１０，１０に対し、引き手レバー８の中間部に設けた貫通孔８ａを支点として限定的に前後回動可能にピン１１，１１で支持する。
【００１３】
前記ラッチ機構は、上記の引き手６および引き手レバー８，８と、引き手レバー８の回動支点のピン１１近傍の扉中心寄りに取り付けた軸支持部材１６，１６で両端を回転可能に支持された垂直の軸１５と、軸１５の両端近傍に固定されて先端部が引き手レバー８，８の後端部にそれぞれ当接する１対の従動レバー１８，１８と、軸１５の両端に固定され且つ軸支持部材１６から扉２を支持する筐体１ａの框部材１ｂ側に突出するラッチ爪２６を有するラッチ具２５、２５と、筐体１ａの框部１ｂの上下の前端部に設けられてラッチ具２５先端のラッチ爪２６がそれぞれ係合する１対のラッチ受け具２７，２７とによって構成される。
【００１４】
一方、前記ラッチ機構の付勢手段即ち、ラッチ具２５先端のラッチ爪２６をラッチ受け具２７の端部に向けて係合方向に付勢する付勢手段は、例えば、軸１５の中間部に扉２で支持されたバネ支持枠２１と、バネ支持枠２１に収納され一端をバネ支持枠２１に他端を軸１５にそれぞれ係止して軸１５を回転付勢するように取り付けた付勢バネ２０とによって構成される。
【００１５】
引き手６は、垂直棒状の中間部材６ａと、中間部材６ａの両端それぞれに引き手レバー８を取り付けた後中間部材６ａの両端に装着する端部部材７，７とで構成する。なお、中間部材６ａは、水平断面形状が前端６ｂを底辺として後端面６ｂ，６ｂを左右の片とする略２等辺三角形になるように形成する。
【００１６】
また、扉２，２ａそれぞれの引き手６が位置する部分には、、上下端近傍に亘って後方に傾斜する傾斜側面４ａと、この傾斜側面４ａの途中からめし合わせ部２ｄに至る扉の表板２ｂと平行に形成した底面４ｂとで形成された後退部（凹状部）４、４を設ける。そして引き手６は、後端側の一部が前記の後退部４に没するような関係にして扉２に取り付ける。
【００１７】
更に、引き手６上下の端部部材７，７の後端には、前記ラッチ機構が扉２を筐体１ａにロックした状態において、両側の扉２，２ａの上下端部の前面にそれぞれ当接する当接端面７ａを有する。当接端面７ａは、図示とは異なるが、両側の扉２，２ａの後退部４，４の底面４ｂ，４ｂに当接するように形成してもよい。
【００１８】
扉２，２ａはそれぞれほぼ対称構造である。扉２，２ａの各表板２ｂは、図５に示すように、矩形の板部材のめし合わせ部２ｄ側に前述の後退部４を形成するとともに該板部材の左右端縁部を裏側に折り曲げてコ字状の折り曲げ部を形成する一方、上下端縁部は裏側にコ字状に折り曲げ且つその端縁を更に筐体１ａ側に向けて水平に折り曲げ更にその端縁を表側に向けコ字状に曲げ、これらの折り曲げ部で剛性を有する構造に成形する。そしてこの表板２ｂの裏面側でめし合わせ部２ｄ寄りに重ね合わせる裏板２ｃは、図３、図５に示すように、矩形の板部材の各端縁部を表板２ｂ側に直角折りして表板２ｂのめし合わせ部２ｄと互いの端部同士が重なるように形成する。裏板２ｃと表板２ｂとを重ね合わせた際に両部材が形成する内部空間の幅方向中間部に挿入して補強するスペーサ３は、縦長矩形の板部材の両側端を表板側に直角織りしてされにその端縁を外側に直角折りした部材である。扉２，２ａは、これらの各部材２ｂ，２ｃ，３を図３，図５に示すように重ね合わせて一体化して形成する。
【００１９】
なお、この扉２，２ａのめし合わせ部２ｄ側の上下コーナー部には、それぞれ引き手支持部材１０，１０ａを装着するための切欠、および、めし合わせ部２ｄ端部からやや扉２の中心側に離隔し且つ筐体１ａの上下の框部１ｂに対峙する箇所には、軸支持部材１６を装着し且つラッチ具２５の先端を筐体１ｂ側に突出させるための切欠をそれぞれ設ける。
【００２０】
筐体１ａの上下の框部１ｂ前端の前記軸支持部材１６を装着する切欠と対峙する箇所には、図２、図３に示すようにラッチ具挿入口１ｃを開口形成する。該ラッチ具挿入口１ｃにはラッチ受け具２７を装着固定する。ラッチ受け具２７は、中央に貫通孔を備えた枠体で、外周がラッチ具挿入口１ｃの内縁に嵌合する形状を有するとともに、周囲にラッチ具挿入口１ｃの裏面に当接する係止爪を設け、この係止爪で框部１ｂに係止固定可能な構造である。
【００２１】
つぎに引き手機構５の各構成部材の更に詳細な構造を以下に説明する。まず、軸支持部材１６および引き手支持部材１０，１０ａについては、詳細な説明は省くが、図５に示すように扉２，２ａの表板２ｂの前記切欠部からそれぞれ押し込んで装着し、スペーサ３と裏板２ｃとで支持できる様に支持用の溝および段状の支持部を有する形状に成形してある。
【００２２】
つぎに、垂直の軸１５は、水平断面が角形であり、中間部には付勢バネ２０の一端を係止するための係止孔（図示しない）と、上下端近傍には軸１５の端部から挿入される従動レバー１８の支持固定部（図示しない）と、両端部にはラッチ具２５の支持固定部と、軸支持部材１６の軸受孔１７に回転可能に支持するための支持部とをそれぞれ有する。従動レバー１８は、先端視コ字状の溝形部材の一端に軸１５が上下に貫通し相対的回転を規制するための角形挿通孔を備えた部材である。バネ支持枠２１は、軸１５が挿通する挿通孔を有する枠体で、側面に係止部２２を突設しその係止部２２上下面には係止爪２２ａを設けている。バネ支持枠２１は、スペーサ３の側面に形成した係止穴２３に挿入して係止爪２２ａで係止保持することができる。付勢バネ２０はコイル状のバネで、バネ支持枠２１の内部に収容保持され、その一端を軸１５に他端をバネ支持枠２１にそれぞれ係止する。ラッチ具２５は、基端に軸１５が上下に貫通し相対的回転を規制するための角形挿通孔を備えるとともに、先端には側方に向けて鉤状に突出するラッチ爪２６を有する部材である。軸支持部材１６は、外側が扉２の表板２ｂの上下端部の折り曲げ部支持される支持部と、後方側面に開口する内部空間と、軸１５の端部を支持する軸受孔１７とを備えている。
【００２３】
上記の各部材を扉２に組み込んで取り付ける手順は、まず始めに、軸１５に付勢バネ２０とバネ支持部２１を装着し、つぎに従動レバー１８を装着して固定支持する。そして軸支持部材１６の内部空間に前記の開口からラッチ具２５の後端を挿入し、ラッチ具２５の軸装着部を軸受孔１７に一致させ、軸１５の端部を軸支持部材１６の軸受孔１７に向けて挿入し、ラッチ具２５を軸１５の端部に装着固定する。そして付勢バネ２０、バネ支持部２１、従動レバー１８、ラッチ具２５，軸支持部材１６を取り付けた軸１５のアッセンブリーの軸支持部材１６，１６を扉２の前記切欠部に装着する。
【００２４】
引き手レバー８は、水平の板状部材で、先端部にネジ孔が貫通形成された部材である。この引き手レバー８のネジ孔部に引き手６の中間部材６ａの端部を突き合わせ、ネジ９，９で固定する。引き手６の中間部材６ａの下端側も同様に引き手レバー８にネジ９，９で固定する。そして上下の引き手の中間部材６ａの上下端のレバー８，８に引き手の端部部材７，７を装着固定し、引き手６を組み立てる。そしてこの組み立てられた引き手６の引き手レバー８部を、引き手支持部材１０に挿入し、引き手レバー８の貫通孔８ａにピン１１を装着して引き手支持部材１０に対し限定的に相対的回動ができるように支持する。そして引き手支持部材１０と引き手６とを組み合わせた状態で扉の表板２ｂのめし合わせ部側上下コーナーの切欠部に引き手支持部材１０，１０を装着する。
【００２５】
そして最後に、扉２の表板２ｂの裏面から、前述の軸支持部材１６をスペーサ３で押さえ、バネ支持枠２１の係止部２２を係止穴２３に挿入して係止爪２２ａで係止し、更に裏板２ｃを重ね合わせて扉２を一体的に組み立てる。なお、左側の扉２ａは引き手６を設けないので、軸１５と軸支持部材１６などは装着せず、引き手支持部材１０と対称で引き手レバー８の支持部を有しない形態の引き手支持部材１０ａを装着し、前記と同様にスペーサ３を重ね合わせ、更に裏板２ｃを重ね合わせて一体化して扉２ａを組み立てる。
【００２６】
つぎに、上記構成からなる引き手機構５の作用を説明する。扉２，２ａが閉じた状態では引き手機構５のラッチ具２５のラッチ爪がラッチ受け具２７に係合して扉２の開放を規制するとともに、引き手６の上下端の端部部材７，７後端の当接端面７ａ，７ａが扉２，２ａの上下端部前面（または図示とは異なるが扉２，２ａの後退部４，４の底面４ｂ，４ｂに当接する構造でもよい）に当接している。そのため扉２ａは、扉２の引き手６に連動作動するラッチ機構で開放が規制されている。この状態で引き手６の中間部材６ａの適宜の箇所を左右いずれかの手で手前に引くと、引き手レバー８，８が前方回動し、引き手レバー８，８の後端に当接している従動レバー１８が後方に押されて回動し軸１５が上端視時計回りに回転する。これにより、ラッチ具２５が右方に回動してラッチ爪２６とラッチ受け具２７との係合が解除され、扉２は前方に開放される。そうすると左方の扉２ａも開放可能となる。
【００２７】
上下のラッチ具２５，２５が１本の軸１５の両端に固定され、互いに同じ角度連動回動するため、引き手６は上下いずれの位置に手を掛けて引いても上下のラッチ具２５，２５とラッチ受け具２７，２７との係合ロックは同期解除される。また、引き手６の後端面６ｃ，６ｃは、扉２，２ａの後退部４，４の傾斜側面４ａ，４ａおよび底面４ｂ，４ｂとの間にそれぞれ適宜の隙間を隔てて位置しているので、左右いずれの側からでも、或いは左右いずれの手を用いても支障無く手を掛けて引く事が可能である。
【００２８】
扉を閉じる際は左方扉２ａが閉じられて状態で右方扉２を閉じると、前記ラッチ具２５，２５がラッチ受け具２７，２７に侵入してラッチ爪２６，２６がラッチ受け具２７，２７と係合し、扉２がロックされ、扉２ａも引き手６の端部部材７，７が当接して開放規制される。
【００２９】
つぎに、図示は省略するが、前述の実施例とは異なる形態の実施例について以下に説明する。まず、引き手６については、中間部材６ａを水平断面が２等辺三角形の形状にせず適宜の形状としてもよい。また扉２，２ａは、引き手の位置に後退部４，４を設けずフラットな前面にしてもよい。その場合、引き手の中間部材の位置する両扉の前面と引き手の中間部材との間に適宜の隙間が生じるようにする。ただし前述の説明のように両扉に後退部を設け、その後退部に引き手中間部材の後端側の一部が没する様にすると、引き手の扉前方への出っ張りが少なく邪魔にならず且つ意匠的にも美観が創出されて都合がよい。
【００３０】
ラッチ機構は、前述のように軸１５に付勢バネ２０を設ける方式とは異なり、従動レバーとラッチ具を上下個別に支持してそれぞれに付勢バネを設けてもよいし、或いは、ラッチ具の後端を延長してその後端に引き手レバーの後端を直接当接させてラッチ具を回動させる形態にしてもよい。但し前述のような実施形態にすると、組立が簡単に行え且つ引き手に手を掛ける位置に無関係にラッチ機構を上下同期的に作動させることができ、作動が安定し、より好ましい形態であるといえる。
【００３１】
つぎに、図６には、図１に示す両開き扉付き収納庫１、および、その扉２に備えた引き手機構５の引き手６と同様の形の引き手３２を、横長３段型引き出し式収納庫３０の各引き出し３１の中央に垂直一直線に並ぶように取り付けた引き出し式収納庫３０を、上下に積み重ねた状態でその外観を示す。本発明に係る両開き扉用の引き手機構の引き手６と同様の形の引き手３２を図６に示すような形態で引き出し式収納庫３０の引き出しの中央に垂直に設け、こｐの収納庫３０を収納庫１と組み合わせて上下に積み重ねると、上下の収納庫の引き手が中央で垂直一直線に並んで上下の引き手のデザインが調和し、新しい意匠的美観を創出することができて都合がよい。
【００３２】
また図示と説明は省略するが、本発明に係る前述の説明の引き手機構５と同様な引き手機構を、通路や出入口の両開き式扉に前述の説明と同様の形態で設けることができる。その場合、前述の収納庫１の扉２の引き手機構５に関する説明と同様、左右いずれの手でも操作が容易に行え、引き手を掴む高さ方向の位置が限定されないといった作用効果が得られ、且つ新しい意匠的美観が創出される。
【００３３】
【発明の効果】
以上にしてなる請求項１に係る発明の両開き扉の引き手機構は、両開き扉の一方の扉のめし合わせ部寄りの上下端近傍にそれぞれ中間部を回転可能に水平支持された１対の引き手レバーを設け、扉のめし合わせ部前方に扉前面との間に隙間を隔てるようにして前記上下引き手レバーの先端同士を連結する垂直の引き手を設け、該引き手で扉開操作をする時の引き手レバーの回動に連動して扉と扉を取り付けた枠体とのロック状態が解除されるラッチ機構を設け、該ラッチ機構をラッチ爪係合方向に付勢する付勢手段を有する構成としたので、人の身長に応じ引き手の適宜の高さに手を掛けて操作できるとともに、左右いずれの方向からでも引き手に手を掛けて開閉操作が行える。そして扉のめし合わせ部のほぼ全体が引き手で覆われるので新しい意匠的美観が創出されるなどの作用効果がある。また、両開き扉の前面の引き手が位置する部分を上下端近傍に亘って後方傾斜させて後退部を形成し、引き手の後端側の一部が前記後退部に没する形態で引き手を取り付けたので、引き手の扉前面からの突出量を少なくして、邪魔にならず且つ意匠的にも美的が創出されるといった作用効果がある。
【００３４】
請求項２に係る発明の両開き扉の引き手機構は、引き手の上下端部を除く中間部を、水平断面が前端を底辺とする略２等辺三角形になるように形成するとともに、該引き手の上下端を引き手レバーの先端にそれぞれ固着したので、扉と引き手の間の隙間に手を挿入しやすく、水平断面が偏平な二等辺三角形にすると軽量で且つ強度的にも安定した構造となり、しかも前方への出っ張りが少なく、機能上優れ且つ意匠的にも美観が創出されるなどの作用効果がある。
【００３６】
請求項３に係る発明の両開き扉の引き手機構は、引き手の上下端部に、ラッチ機構が扉を枠体にロックした状態において、両側の扉の前面または前記後退部の前面にそれぞれ当接する端面を設けたので、ラッチ付き扉の引き手が相手側扉のめし合わせ部近傍の上下端に当接して扉の開放を規制するといった作用効果がある。またこれにより両方の扉に引き手とラッチ機構をそれぞれ設ける必要が無くなるので、製造コストを低減することができるといった効果が得られる。
【００３７】
請求項４に係る発明の両開き扉の引き手機構は、引き手レバーの支点近傍の扉内部または扉裏面に垂直の回転軸を設け、該軸の両端近傍に先端部が上下の引き手レバー後端部に当接して回動する１対の従動レバーを固定するとともに、前記軸の両端には扉を支持する枠体の上下前端部のラッチ受けと係合するラッチ爪を固定し、且つ、前記軸にラッチ爪をラッチ受けに対し係合方向に付勢する付勢バネを設けてなるラッチ機構を備えたので、上下のラッチ爪が確実に連動するとともに、引き手を手前に引く位置が引き手の上下方向中心位置でなくても、即ち上下の引き手レバーの回動角度が一致しなくても、上下のラッチ爪が互いに同じ角度回転し、上下ラッチ爪のそれぞれに対し付勢力が均等に作用して、安定的な同期作動をするといった作用効果がある。

BACKGROUND OF THE INVENTION
The present invention relates to a technique of a double door puller attached to the left or right of furniture or a passage, and more specifically, a vertical puller covering a substantially whole area of the fitting portion at a fitting portion of the double door and its The present invention relates to a puller structure that includes a latch mechanism that operates in conjunction with an operation of pulling a puller and that can be operated by placing a hand on an arbitrary position in the height direction and that can be easily operated with either the left or right hand.
[0002]
[Prior art]
A conventional puller for a storage cabinet with double doors is provided with a puller operated with the left hand on the left door and a puller operated with the right hand on the right door in the vicinity of the fitting portion of the left and right doors. . In such a storage, when a person with one hand is incapable of opening and closing the door on the side opposite to the dominant hand, it is necessary to place the hand on the pulling hand with the palm facing the opposite side. In addition, when a storage with double doors is stacked and installed on the upper stage, it may be difficult for a person with a short height to open and close the door of the storage.
[0003]
On the other hand, for example, when stacking a storage with a double door on the upper stage of a horizontally long drawer-type storage, the drawer puller of the drawer-type storage is in the center of the front plate of the drawer developed by the applicant of the present application. A storage box with a vertical puller that extends near the upper and lower ends of the drawer, and the puller of each drawer is connected in a straight line and can be pulled out with one hand. In this case, the puller of the lower storage and the puller of the upper storage are different, and the appearance is unbalanced and a sense of incongruity is felt. In such a case, a unified design aesthetic can be created by arranging the puller of the storage with the double door of the upper tier in a form that is connected to the puller of the lower tier in a straight line perpendicular to the center. . In this case, the puller needs to have a function of releasing the engagement of the latch mechanisms provided above and below the door in conjunction with the pulling operation.

Note that the pull levers 8 and 8 are through holes provided in an intermediate portion of the pull lever 8 with respect to the pair of pull support members 10 and 10 attached to the upper and lower ends in the vicinity of the mating portion on the back surface of the door 2. 8a is used as a fulcrum, and is supported by pins 11 and 11 so as to be able to rotate back and forth in a limited manner.
[0013]
The latch mechanism can be rotated at both ends by the above-described pulling handle 6 and pulling levers 8 and 8 and shaft support members 16 and 16 attached near the center of the door near the pin 11 of the pivoting fulcrum of the pulling lever 8. A supported vertical shaft 15, a pair of driven levers 18, 18 that are fixed in the vicinity of both ends of the shaft 15 and whose front ends abut against the rear end portions of the pull levers 8, 8, and both ends of the shaft 15, respectively. Latch tools 25 and 25 having latch claws 26 that are fixed and project from the shaft support member 16 to the side of the flange 1b of the housing 1a that supports the door 2, and provided at the upper and lower front ends of the flange 1b of the housing 1a. And a pair of latch receivers 27 and 27 with which the latch claws 26 at the tip of the latch tool 25 are respectively engaged.
[0014]
On the other hand, the urging means of the latch mechanism, that is, the urging means for urging the latch claw 26 at the tip of the latch 25 toward the end of the latch receiver 27 in the engaging direction is, for example, at the intermediate portion of the shaft 15. A spring support frame 21 supported by the door 2 and a bias that is housed in the spring support frame 21 and is attached so that one end is locked to the spring support frame 21 and the other end is locked to the shaft 15 and the shaft 15 is rotationally biased. And a spring 20.
[0015]
The puller 6 includes a vertical bar-shaped intermediate member 6a and end members 7 and 7 which are attached to both ends of the intermediate member 6a after the pull lever 8 is attached to both ends of the intermediate member 6a. The intermediate member 6a is formed so that the horizontal cross-sectional shape is a substantially isosceles triangle having the front end 6b as a base and the rear end surfaces 6b and 6b as left and right pieces.
[0016]
Further, in the portion where the pull handle 6 of each of the doors 2 and 2a is located, there are an inclined side surface 4a inclined rearward in the vicinity of the upper and lower ends, and a door surface extending from the middle of the inclined side surface 4a to the mating portion 2d. Recessed portions (concave portions) 4 and 4 formed by a bottom surface 4b formed in parallel with the plate 2b are provided. The puller 6 is attached to the door 2 in such a relationship that part of the rear end side is submerged in the retracted portion 4.
[0017]
Further, at the rear ends of the upper and lower end members 7, 7 of the pull handle 6, the latch mechanism contacts the front surfaces of the upper and lower ends of the doors 2, 2 a on both sides when the door 2 is locked to the housing 1 a. It has an abutting end face 7a in contact therewith. The contact end surface 7a may be formed so as to contact the bottom surfaces 4b and 4b of the retracted portions 4 and 4 of the doors 2 and 2a on both sides, although not shown.
[0018]
Each of the doors 2 and 2a has a substantially symmetrical structure. As shown in FIG. 5, the front plates 2b of the doors 2 and 2a are formed with the above-described retracted portion 4 on the mating portion 2d side of the rectangular plate member, and the right and left edge portions of the plate member are folded back. The U-shaped bent part is formed, while the upper and lower end edges are folded in a U-shape on the back side, the edge is further folded toward the housing 1a side, and the edge is directed toward the front side. And bent into a shape having rigidity at these bent portions. Further, the back plate 2c to be overlapped near the mating portion 2d on the back side of the front plate 2b is formed by folding each end edge portion of the rectangular plate member to the front plate 2b side as shown in FIGS. The mating portion 2d of the front plate 2b and the end portions thereof are formed so as to overlap each other. When the back plate 2c and the front plate 2b are overlapped with each other, the spacer 3 that is inserted into the intermediate portion in the width direction of the internal space formed by the two members to reinforce the both sides of the vertically long rectangular plate member is perpendicular to the front plate side. It is a member that is woven and has its edges folded at right angles outward. The doors 2 and 2a are formed by overlapping these members 2b, 2c and 3 as shown in FIGS.
[0019]
It should be noted that the upper and lower corners on the mating part 2d side of the doors 2 and 2a are respectively provided with notches for attaching the pull support members 10 and 10a, and the center side of the door 2 slightly from the end of the mating part 2d. A notch for mounting the shaft support member 16 and projecting the tip of the latching tool 25 toward the housing 1b is provided at a location that is spaced apart from each other and faces the upper and lower flanges 1b of the housing 1a.
[0020]
As shown in FIG. 2 and FIG. 3, a latch tool insertion opening 1c is formed at a position facing the notch for mounting the shaft support member 16 at the front end of the upper and lower flanges 1b of the housing 1a. A latch receiving tool 27 is attached and fixed to the latch tool insertion opening 1c. The latch receiving device 27 is a frame having a through-hole at the center, and has a shape in which the outer periphery is fitted to the inner edge of the latch device insertion port 1c, and a latching claw that abuts on the back surface of the latch device insertion port 1c. This is a structure that can be locked and fixed to the collar portion 1b with the locking claw.
[0021]
Next, a more detailed structure of each component of the pulling mechanism 5 will be described below. First, the shaft support member 16 and the puller support members 10 and 10a will not be described in detail, but as shown in FIG. 5, they are pushed in from the notches of the front plate 2b of the doors 2 and 2a, respectively. 3 and the back plate 2c are formed into a shape having a support groove and a stepped support portion.
[0022]
Next, the vertical shaft 15 has a square horizontal cross section, a locking hole (not shown) for locking one end of the biasing spring 20 in the middle, and the end of the shaft 15 near the upper and lower ends. A supporting and fixing part (not shown) of the driven lever 18 inserted from the part, a supporting and fixing part of the latch tool 25 at both ends, and a supporting part for rotatably supporting the bearing hole 17 of the shaft support member 16 Respectively. The driven lever 18 is a member provided with a square insertion hole for restricting the relative rotation by allowing the shaft 15 to vertically penetrate one end of a U-shaped groove-shaped member as viewed from the front end. The spring support frame 21 is a frame body having an insertion hole through which the shaft 15 is inserted, and a locking portion 22 protrudes from a side surface, and a locking claw 22a is provided on the top and bottom surfaces of the locking portion 22. The spring support frame 21 can be inserted into a locking hole 23 formed on the side surface of the spacer 3 and can be locked and held by a locking claw 22a. The biasing spring 20 is a coiled spring and is housed and held inside the spring support frame 21, and one end thereof is locked to the shaft 15 and the other end is locked to the spring support frame 21. The latch tool 25 is a member that has a rectangular insertion hole for allowing the shaft 15 to penetrate vertically and restrict relative rotation at the base end, and a latch claw 26 that protrudes in a hook shape toward the side at the tip. is there. The shaft support member 16 includes a support portion that supports the bent portions of the upper and lower end portions of the front plate 2b of the door 2, an internal space that opens to the rear side surface, and a bearing hole 17 that supports the end portion of the shaft 15. I have.
[0023]
The procedure for incorporating each member into the door 2 is as follows. First, the urging spring 20 and the spring support portion 21 are mounted on the shaft 15, and then the driven lever 18 is mounted and fixedly supported. Then, the rear end of the latch device 25 is inserted into the inner space of the shaft support member 16 from the opening, the shaft mounting portion of the latch device 25 is made to coincide with the bearing hole 17, and the end portion of the shaft 15 is made the bearing of the shaft support member 16. The latch tool 25 is attached and fixed to the end of the shaft 15 by being inserted toward the hole 17. Then, the shaft support members 16 and 16 of the assembly of the shaft 15 to which the biasing spring 20, the spring support portion 21, the driven lever 18, the latch tool 25, and the shaft support member 16 are attached are mounted on the notch portion of the door 2.
[0024]
The pull lever 8 is a horizontal plate-like member having a screw hole formed through the tip. The end of the intermediate member 6 a of the pull handle 6 is brought into contact with the screw hole of the pull lever 8 and fixed with screws 9 and 9. Similarly, the lower end side of the intermediate member 6 a of the puller 6 is fixed to the puller lever 8 with screws 9 and 9. Then, the end members 7 and 7 are attached and fixed to the levers 8 and 8 at the upper and lower ends of the middle member 6a of the upper and lower pullers, and the puller 6 is assembled. Then, the pull lever 8 of the assembled pull handle 6 is inserted into the pull support member 10, and the pin 11 is attached to the through hole 8 a of the pull lever 8 to limit the pull support member 10. Supports relative rotation. Then, with the puller support member 10 and the puller 6 combined, the puller support members 10 and 10 are mounted in the cutouts in the upper and lower corners of the mating portion side of the door front plate 2b.
[0025]
Finally, from the back surface of the front plate 2b of the door 2, the shaft support member 16 is pressed by the spacer 3, the locking portion 22 of the spring support frame 21 is inserted into the locking hole 23, and the locking claw 22a is engaged. Then, the door 2 is assembled as a unit by overlapping the back plate 2c. Since the left door 2a does not have the pull handle 6, the shaft 15 and the shaft support member 16 and the like are not mounted, and the pull handle has a form that is symmetrical to the pull support member 10 and does not have the support portion of the pull lever 8. The support member 10a is mounted, the spacers 3 are overlapped in the same manner as described above, and the back plate 2c is overlapped and integrated to assemble the door 2a.
[0026]
Next, the operation of the pulling mechanism 5 having the above configuration will be described. When the doors 2 and 2a are closed, the latch claw of the latching tool 25 of the pulling mechanism 5 engages with the latch receiving tool 27 to restrict the opening of the door 2, and the end members 7 at the upper and lower ends of the pulling handle 6 are used. , 7 The abutting end surfaces 7a, 7a at the rear end are the front surfaces of the upper and lower ends of the doors 2, 2a (or, although not shown in the figure, they may abut against the bottom surfaces 4b, 4b of the retreating parts 4, 4 of the doors 2, 2a) Abut. Therefore, the opening of the door 2 a is restricted by a latch mechanism that operates in conjunction with the puller 6 of the door 2. In this state, when an appropriate portion of the intermediate member 6a of the pull handle 6 is pulled forward with either the left or right hand, the pull levers 8 and 8 are rotated forward and come into contact with the rear ends of the pull levers 8 and 8. The driven lever 18 is pushed backward to rotate, and the shaft 15 rotates clockwise as viewed from the upper end. As a result, the latch device 25 rotates to the right, the engagement between the latch claw 26 and the latch receiver 27 is released, and the door 2 is opened forward. Then, the left door 2a can be opened.
[0027]
Since the upper and lower latching tools 25, 25 are fixed to both ends of the single shaft 15 and rotate in conjunction with each other at the same angle, the upper and lower latching tools 25, 25 The engagement lock between the latch 25 and the latch receivers 27 is released. Further, the rear end surfaces 6c and 6c of the pull handle 6 are positioned with an appropriate gap between the inclined side surfaces 4a and 4a and the bottom surfaces 4b and 4b of the retracted portions 4 and 4 of the doors 2 and 2a. It is possible to draw the hand without any trouble from either the left or right side or the right or left hand.
[0028]
When closing the door, when the left door 2a is closed and the right door 2 is closed, the latch devices 25 and 25 enter the latch receivers 27 and 27, and the latch claws 26 and 26 are latch latches 27. 27, the door 2 is locked, and the door 2a is also restricted from opening by the end members 7 and 7 of the pull handle 6 coming into contact with each other.
[0029]
Next, although not shown, an embodiment having a different form from the above-described embodiment will be described below. First, for the puller 6, the intermediate member 6a may have an appropriate shape instead of the isosceles triangle in the horizontal section. Further, the doors 2 and 2a may be flat front surfaces without providing the retracting portions 4 and 4 at the position of the pulling handle. In that case, an appropriate gap is formed between the front surfaces of both doors where the intermediate member of the puller is located and the intermediate member of the puller. However, as described above, if both doors are provided with receding parts and a part of the rear end side of the intermediate handle is submerged in the receding parts, the protrusion of the pulling doors in front of the doors is less likely to interfere. It is convenient because it creates a beautiful aesthetic.
[0030]
Unlike the system in which the biasing spring 20 is provided on the shaft 15 as described above, the latch mechanism may support the driven lever and the latching tool individually and provide the biasing springs respectively. The latch tool may be rotated by extending the rear end and bringing the rear end of the pull lever directly into contact with the rear end. However, in the above-described embodiment, the assembly can be easily performed and the latch mechanism can be operated in a vertical synchronous manner irrespective of the position where the hand is put on the puller. I can say that.
[0031]
Next, FIG. 6 shows a storage box 1 with double doors shown in FIG. 1 and a puller 32 having the same shape as the puller 6 of the puller mechanism 5 provided in the door 2. The external appearance of the drawer-type storage 30 attached so as to be aligned in a vertical straight line at the center of each drawer 31 of the type storage 30 is shown in the state of being stacked up and down. A puller 32 having the same shape as the puller 6 of the pulling mechanism for double doors according to the present invention is provided vertically in the center of the drawer of the pull-out storage 30 in the form as shown in FIG. When the storage 30 is combined with the storage 1 and stacked up and down, the upper and lower storage handles are arranged in a straight line in the center, and the design of the upper and lower pullers is harmonized, creating a new design aesthetic. convenient.
[0032]
Although not shown and described, a pulling mechanism similar to the pulling mechanism 5 described above according to the present invention can be provided in the same manner as described above in the double doors of the passage and the entrance / exit. In that case, as in the description of the pulling mechanism 5 of the door 2 of the storage 1 described above, the operation effect can be obtained that the operation can be easily performed with either the left or right hand, and the position in the height direction for gripping the pulling hand is not limited. And new design aesthetics are created.
[0033]
【The invention's effect】
In the double door pulling mechanism according to the first aspect of the present invention as described above, a pair of pulling mechanisms in which the intermediate portion is horizontally supported in the vicinity of the upper and lower ends near the fitting portion of one door of the double door. A hand lever is provided, and a vertical puller that connects the tips of the upper and lower puller levers is provided in front of the door fitting part so that there is a gap between the front of the door and the door can be opened with the puller. A latch mechanism that releases the locked state of the door and the frame body to which the door is attached in conjunction with the rotation of the pull lever when the lever is engaged, and biasing means for biasing the latch mechanism in the latch claw engagement direction Therefore, according to the height of the person, it can be operated by placing the hand at an appropriate height of the puller, and can be opened and closed by placing the hand on the puller from either the left or right direction. And since almost the entire fitting part of the door is covered with a pulling handle, there is an effect such as the creation of a new design aesthetic. Further, the part where the pull handle on the front of the double door is located is inclined rearward over the vicinity of the upper and lower ends to form a retreat part, and a part of the rear end side of the pull handle is submerged in the retreat part. Therefore, the amount of protrusion from the front face of the door of the puller is reduced, and there is an effect that the design is not disturbed and aesthetics are created.
[0034]
In the double door puller mechanism according to the second aspect of the invention, the intermediate portion excluding the upper and lower ends of the puller is formed so that the horizontal cross section is a substantially isosceles triangle with the front end as the base, and the puller Since the upper and lower ends are fixed to the tip of the pull lever respectively, it is easy to insert a hand into the gap between the door and the pull handle, and if the horizontal cross section is an isosceles triangle, the structure is lightweight and stable in strength. In addition, there are few effects such as a bulge forward, an excellent function, and a beautiful design.
[0036]
According to a third aspect of the invention, the double door puller mechanism is respectively applied to the upper and lower ends of the puller and to the front surface of the doors on both sides or the front surface of the retracted portion when the latch mechanism locks the door to the frame. Since the contact end surface is provided, there is an effect that the handle of the latched door is brought into contact with the upper and lower ends in the vicinity of the mating portion of the mating door to restrict the opening of the door. Further, this eliminates the need to provide a pulling mechanism and a latch mechanism on both doors, so that the manufacturing cost can be reduced.
[0037]
In the double door puller mechanism according to the fourth aspect of the present invention, a vertical rotating shaft is provided in the door near the fulcrum of the puller lever or on the rear surface of the door, and the tip of the puller lever is located at both ends of the shaft. A pair of driven levers that rotate in contact with the end portions are fixed, and latch claws that engage with latch receivers at the upper and lower front end portions of the frame body that supports the door are fixed to both ends of the shaft, and Since the latch mechanism is provided with an urging spring for urging the latch pawl in the engaging direction with respect to the latch receiver on the shaft, the upper and lower latch claws are interlocked with each other and the position where the puller is pulled forward is determined. Even if the vertical position of the pulling lever is not the same, that is, the rotation angle of the upper and lower pulling levers does not match, the upper and lower latching pawls rotate at the same angle, and the urging force is applied to each of the upper and lower latching claws. Acts evenly and performs stable synchronous operation There is a use effect.
