Description

【０００１】
【発明の属する技術分野】
本発明は、引き戸を好適にスライド移動させることができるスライド部材、及びそれを利用した引き戸並びに収納家具に関するものである。
【０００２】
【従来の技術】
従来より、収納家具本体の収納空間を開閉するためにスライド式の引き戸を設けた収納家具が種々考えられている。このような収納家具では、収納家具本体の開口部における上縁部又は下縁部若しくはこれらの両方に引き戸の幅方向に沿って延びるレール部を形成する一方、このレール部に対応して引き戸には転動可能なローラ等を備えたスライド部材が設けられているのが通例である（例えば、特許文献１参照）。このようなスライド部材は、ローラを有するものを例に挙げると、引き戸に固定して設けられたホルダと、このホルダに軸支させたローラとを具備している。

【０００４】
【発明が解決しようとする課題】
ところが、上述のような従来の収納家具において、天板に比較的重いものを載せている場合にはその天板が載置物の荷重によって下方に撓むこととなって、天板が引き戸の上端部側のローラを下方へ強く押さえつけた状態となり、ローラの回転が阻害される。すなわち、本来引き戸の開閉をスムーズに行わしめるためにホルダに軸支させたローラがその機能を奏し得なくなってしまう。斯かる不具合は、この種の収納家具にのみ生じるものではなく、居室の出入口等に設けられるスライドドア式の引き戸など、引き戸一般について共通し、ローラを含めてスライド部材一般にも共通する。すなわち、引き戸のスライド移動を案内するためにドア枠の上端部側に設けられるレール部が長尺のものであると、レール部の自重によって長手方向中央部で撓みが生じやすく、その結果、レール部が引き戸の上端部に設けたスライド部材を強く押さえつけることとなって、引き戸の開閉に障害が生じるおそれがある。
【０００５】
そこで本発明は、以上のような問題に鑑みて、収納家具における天板の上載荷重によっても引き戸の開閉が阻害されることのないスライド部材を提供するとともに、このスライド部材を利用した優れた引き戸並びに収納家具をも提供することを主目的とし、さらには収納家具のみならず引き戸全般に適用できる好適なスライド部材を提供しようとするものである。
【０００６】
【課題を解決するための手段】
すなわち、本発明に係るスライド部材は、天板を備えた収納家具本体に対して引き戸をスライド移動可能に設けるに際して、引き戸の上端部又は収納家具本体の天板の下面側における収納空間を開放する開口部の開口上縁部の何れか一方に取り付けられるものであって、前記開口上縁部又は引き戸の何れか他方に設けられたレール部に対する相対位置関係を略一定に保ち得る相対位置維持手段を具備していることを特徴としている。
【０００７】
このような構成のスライド部材であれば、天板に重量物を載せた場合や天板自体が下方に撓んだ場合であっても、相対位置維持手段によってスライド部材はレール部に対して常に略一定の位置関係、特に上下方向の位置関係を保つので、スライド部材のレール部に対する相対的なスライド移動がスムーズな状態で維持されるその結果、このようなスライド部材を上端部に設けた引き戸は、収納家具本体に対して常にスムーズに開閉動作を行うことになる。なお、スライド部材は、収納家具本体の開口部のうち開口上縁部に設けてもよいし、引き戸の上端部に設けてもよい。他方、レール部は、スライド部材とは反対側の部材に設けることになる。そして、本発明は以下に述べるような構成を加えることで、さらにスムーズな引き戸の開閉動作を実現することができる。
【０００８】
まず、スライド部材は、レール部にスライド移動を案内されるスライダと、このスライダを保持し引き戸又は収納家具本体の開口上縁部に取り付けられるホルダとを具備するものとして、このホルダに、スライダのレール部に対する相対位置を略一定に保つ前記相対位置維持手段を形成して、主としてスライド移動を営むスライダと、スライダを保持しつつそのレール部に対する位置関係を維持するホルダとに機能を分担させることで、構成の簡素化を図ることができる。
【０００９】
特に相対位置維持手段として簡易な構造のものには、弾性変形を利用するものが挙げられる。具体的には、相対位置維持手段を、ホルダに形成した弾性変形可能な板バネ部から構成すれば、ホルダ自体に弾性体としての機能を付与することができるので、ホルダとは別体のコイルバネやゴム弾性体等の弾性部材を用いる必要がなくなり、構造の簡素化をより一層向上することができる。ここで板バネ部には、反レール部側へ湾曲させたものも含まれる。
【００１０】
さらに、板バネ部が平板状をなすものである場合には、この板バネ部に反レール部側へ突出する突起部を形成し、突起部が反レール部側である引き戸又は収納家具本体の開口上縁部に当接することによって板バネ部を弾性変形させるように構成することが望ましい。
【００１１】
このような板バネ部をホルダに容易に形成するための構成としては、ホルダにおいてレール部と対面する対向壁部に対をなすスリットを形成するとともに、これらスリットに挟まれた部位を前記板バネ部としたものが挙げられる。
【００１２】
また、スライダのレール部に対する相対位置関係を維持するという板バネ部の主機能を阻害することなくホルダに適切な役割を果たさせるには、ホルダにおいて前記板バネ部とは異なる部位に、引き戸又は収納家具本体の開口縁部に遊嵌、すなわち所定のクリアランスを持って嵌め合わせて取り付けるための取付部を形成するとよい。
【００１３】
スライダとして好適なものには、レール部に沿って転動し得るようにホルダに軸支されたローラを挙げることができる。
【００１４】
以上のような構成のスライダを備えた本発明に係る収納家具における引き戸は、要するに、天板を備えた収納家具本体の収納空間を開放する開口部のうち開口上縁部に配置されたレール部に対して前記収納空間を開閉すべくスライド移動可能に設けられる引き戸であって、上述のスライド部材をレール部に対向する上端部に配置したものであるので、簡易な構成でスムーズな開閉動作を実現することができる。
【００１５】
さらに、収納家具本体における開口下縁部にも開口上縁部と同一構成のレール部を配置している場合、当該開口下縁部におけるレール部に対向する下端部に上端部側のスライド部材と同一構成のスライド部材を配置すれば、部材の共通化とコストダウン、スライダの取付作業の迅速化を図ることができる。なお、引き戸の下端部側においては、引き戸自体の自重によって下端部側のスライド部材における相対位置維持手段は常に作用していることになる。
【００１６】
また、上述した構成のスライダを備えた本発明に係る収納家具は、天板を備えるとともに所定の収納空間を有する収納家具本体と、収納空間を開閉すべくこの収納空間を開放する開口部に配置される引き戸とを具備するものであり、収納家具本体において前記開口部のうち開口上縁部又は引き戸の上端部の何れか一方にレール部を設けるとともに、他方に上述のスライド部材を設けていることを特徴とするものであるので、天板への上載荷重の有無に拘わらず、引き戸を収納家具本体に対してスムーズに開閉することが可能である。
【００１７】
さらに、この収納家具において部材の共通化やコストダウン、組立作業の利便性を向上するには、収納家具本体の前記開口部のうち開口下縁部又は引き戸の下端部の何れか一方にも前記レール部と同一構成のレール部を設けるとともに、他方に前記スライド部材と同一構成のスライド部材を設けるとよい。
【００１８】
なお、本発明は、上述した収納家具の引き戸に適用されるスライド部材に限らず、スライド式ドア等の引き戸全般にも適用できるものである。そのための構成を有する本発明は、固定物に対して引き戸をスライド移動可能に設けるに際して、前記固定物又は引き戸の何れか一方に取り付けられるものであって、前記固定物又は引き戸の何れか一方に設けられたレール部に対する相対位置関係を略一定に保ち得る相対位置維持手段を具備していることとなる。例えば居室や建物の出入口に設けられる引き戸にこのスライド部材を適用する場合には、固定物たるドア枠に設けたレール部の自重による撓みが生じてもそれに対応して相対位置維持手段が機能し、スライド部材のレール部に対する相対位置関係がほぼ一定に保たれるので、引き戸の好適でスムーズな開閉動作を維持することができる。
【００１９】
【発明の実施の形態】
以下、本発明の一実施形態を、図面を参照して説明する。
【００２０】
この実施形態は、ロッカー等の収納家具Ｒに設けられる第１引き戸Ｄ１及び第２引き戸Ｄ２に適用したスライド部材１である。
【００２１】
まず、この収納家具Ｒ全体の構成について簡単に説明する。
【００２２】
図１に示すように、収納家具Ｒは、所定の収納空間ＲＦを有し前面Ｒ１に前記収納空間ＲＦを外部へ開放し得る開口部ＲＭを形成した収納家具本体Ｒ０と、開口部の開口縁部ＲＭ１においてスライド移動によりこの開口部ＲＭを開閉する右側及び左側の引き戸（以下「第一引き戸Ｄ１」及び「第２引き戸Ｄ２」と称す）とを備えたものである。
【００２３】
収納具本体Ｒ０は、例えばスチール素材を折り曲げて成形してなる天板Ｒ２、底板Ｒ３、左右一対の側板Ｒ４、背板Ｒ５を筐形に組み付けることによって前面Ｒ１に前記開口部ＲＭを形成しているものである。なお、説明の便宜上、以下の説明においては、開放させている一端側を前端部とし、背板が位置する一端側を後端部とする。
【００２４】
天板Ｒ２は、平面視略矩形状をなしたものであり、この天板Ｒ２の対向位置には天板Ｒ２と略同型の底板Ｒ３が設けられている。また、天板Ｒ２の下面側前端部及び底板Ｒ３の上面側前端部の幅方向略全域に引き戸のスライド移動を案内するレール部２をそれぞれ設けている。そして、この天板Ｒ２及び底板Ｒ３を両側板Ｒ４の上端部間及び下端部間に架け渡して設けるとともに、両側板Ｒ４の後端部間に背板Ｒ５を固定した状態で設けている。なお、側板Ｒ４の前端側の所定箇所に後述するラッチ機構Ｌの一部を構成する被係留部を有している（図示省略）。
【００２５】
図２に示すように、レール部２は、開口縁部ＲＭ１の幅方向略全域の長さを有し、スライド部材１を具備した第１引き戸Ｄ１と第２引き戸Ｄ２が収納空間ＲＦの開閉のためにスライド移動し得るように案内するものである。そのための構成として第１引き戸Ｄ１用と第２引き戸Ｄ２用の２本のチャンネル状をなすレール溝２１を、前後に対をなすように長手方向全域に亘って形成している。そして各レール部２には天板Ｒ２の下面側前端部及び底板Ｒ３の上面側前端部に取り付けるための取付孔２ｈが複数箇所（本実施形態では３カ所）設けられており、上側レール部２はレール溝２１を下方へ開口させた姿勢で、下側のレール部２は、レール溝２１を上方へ開口させた姿勢でそれぞれ前記取付孔２ｈに挿入されるねじ等（図示省略）によって天板Ｒ２の下面側前端部及び底板Ｒ３の上面側前端部に取り付けられる。
【００２６】
図１に示すように、前方に位置する右側の第１引き戸Ｄ１及び第１引き戸Ｄ１の後方に位置する左側の第２引き戸Ｄ２は、天板Ｒ２及び底板Ｒ３に設けた前記レール部２を利用して前記開口縁部幅方向にスライド移動するものであり、いずれも正面視矩形状をなすスチール板等から構成される。第１引き戸Ｄ１及び第２引き戸Ｄ２の上端部及び下端部の所定箇所には、前記レール部２に案内されるスライド部材１をそれぞれ左右一対にして設けている。また、各第１引き戸Ｄ１及び第２引き戸Ｄ２は一方の側縁部に沿って略全域に亘って設けた引手Ｍと、引手Ｍの高さ方向略中央部において第１引き戸Ｄ１及び第２引き戸Ｄ２を収納家具本体Ｒ０の一部に係留するためのラッチ機構Ｌとを備えている。引手Ｍは、例えば合成樹脂素材を押し出し成形してなり、上端から下端に亘って前面側Ｒ１に開口する指掛け部Ｍ１を一体に形成したものである。指掛け部Ｍ１は、その一部に指先を掛けて操作できるように標準的な成人の指先が十分に入るスペースを有するものである。ラッチ機構Ｌは、側板Ｒ４の前端側に形成した被係留部（図示省略）に係留し得る係留爪を有するものであり前記引手Ｍの操作によって同期作動可能に構成されている。なお、本実施形態では、引手Ｍの回転動作を安定したものにするために、第１引き戸Ｄ１及び第２引き戸Ｄ２の上下の端部近傍部位に適宜の回転動作補助部材を取り付けている。また、第１引き戸Ｄ１にロック装置Ｎを設け第１引き戸Ｄ１及び第２引き戸Ｄ２を閉じた状態で施錠することによって、第１引き戸Ｄ１及び第２引き戸Ｄ２の移動を禁止するようにしている。
【００２７】
図３に示すように、スライド部材１は、第１引き戸Ｄ１及び第２引き戸Ｄ２の上端部及び下端部に各２カ所ずつ設けられるものであり、いずれも同一構成を有するため、ここでは第２引き戸Ｄ２の上側のスライド部材１の一方について、その構造を説明する。このスライド部材１は、前記レール部２に沿って転動するスライダたるローラ１Ａと、このローラ１Ａを保持し第２引き戸Ｄ２に取り付けられるホルダ１Ｂから構成されている。
【００２８】
図４（ａ）にローラ１Ａの正面図、（ｂ）にローラ１Ａの側面図を示す。ローラ１Ａは、例えば樹脂素材にて円盤状の大径部１Ａ１と小径部１Ａ２とを一体に形成したものである。大径部１Ａ１と小径部１Ａ２は同一の水平軸を共有しており、それらの中央部に水平方向に貫通する貫通孔１Ａｈを形成している。大径部１Ａ１は、レール部２のレール溝２１内を転動するようにレール溝２１の開口幅よりも薄い肉厚を有しており、小径部１Ａ２はレール部２の下面２２に沿って転動し大径部１Ａ１の位置決めを行っている。
【００２９】
図５〜図１１に示すように、ホルダ１Ｂは、第１ホルダ要素１Ｂ１と第２ホルダ要素１Ｂ２とからなり、これら第１ホルダ要素１Ｂ１と第２ホルダ要素１Ｂ２との間にローラ１Ａを挟んで回転可能に保持するように組み立てられる半割構造の部材である。なお、図５（ａ）は第１ホルダ要素１Ｂ１の外側正面図、同（ｂ）に第２ホルダ要素１Ｂ２の外側正面図を示している。図６（ａ）に第１ホルダ要素１Ｂ１の内側正面図、同（ｂ）に第２ホルダ要素１Ｂ２の内側正面図を示している。図７に（ａ）第１ホルダ要素１Ｂ１の側面図、同（ｂ）に第２ホルダ要素１Ｂ２の側面図を示している。第１ホルダ要素１Ｂ１は、矩形状をなす起立壁１Ｂ１１とこの起立壁１Ｂ１１から第２ホルダ要素１Ｂ２側へ突出させた底壁１Ｂ１２及び側壁１Ｂ１３とから構成される合成樹脂一体成形品である。一方、第２ホルダ要素１Ｂ２も前記第１ホルダ要素１Ｂ１と略同様の大きさ及び形状の起立壁１Ｂ２１と底壁１Ｂ２２及び側壁１Ｂ２３とから構成される合成樹脂一体成形品である。尚、これら第１ホルダ要素１Ｂ１と第２ホルダ要素１Ｂ２は金属製の部材とすることもできる。
【００３０】
図５（ａ）、図６（ａ）及び図７（ａ）に示すように、第１ホルダ要素１Ｂ１の起立壁１Ｂ１１における内面１Ｂ１１ａの中央部には、第２ホルダの起立壁１Ｂ２１に向けて略水平方向に突出する中空の円筒突部１Ｂ１４を形成している。この円筒突部１Ｂ１４は、ローラ１Ａの回転軸として機能するものであり、外径寸法をローラ１Ａの貫通孔１Ａｈの直径より若干小さくしている。また、この円筒突部１Ｂ１４の下方、すなわち起立壁１Ｂ１１から第２ホルダ要素１Ｂ２側へ突出させた側壁１Ｂ１３の下端部には、第２ホルダ要素１Ｂ２との組み立てのために用いられる係合孔１Ｂ１５を２つ形成している。さらに、起立壁１Ｂ１１の外面１Ｂ１１ｂにおける中央部には、第２引き戸Ｄ２へ取り付けるための弾性変形可能な取付部たる係合爪１Ｂ１６を形成している。この係合爪１Ｂ１６は起立壁１Ｂ１１の外面１Ｂ１１ｂの中央部よりも下端部側に形成してある。係合爪１Ｂ１６の周囲３方は起立壁１Ｂ１１を貫通させた角孔１Ｂ１７によって開放されており、底壁１Ｂ１２側でのみ起立壁１Ｂ１１と繋がっている。具体的に説明すると、この係合爪１Ｂ１６は、側面視三角形状をなして起立壁１Ｂ１１から突出している。すなわち係合爪１Ｂ１６の外面は、起立壁１Ｂ１１との連結部位を基端として約１０°の角度をなして上方へ傾斜する下向きのテーパ面１Ｂ１６aと下向きテーパ面１Ｂ１６aの上端を基端として、起立壁１Ｂ１１の外面１Ｂ１１ｂと約３０°の角度をなして上方へ傾斜する上向きテーパ面１Ｂ１６ｂとから構成される。従って、この係合爪１Ｂ１６は下向きテーパ１Ｂ１６ａ面又は上向きテーパ面１Ｂ１６ｂのいずれかに外方から力が作用すると、起立壁１Ｂ１１との連結部分の弾性変形によって角孔１Ｂ１７内へ押し込まれることになる。さらに図５（ａ）に示すように、この係合爪１Ｂ１６を挟むように、外面１Ｂ１１ｂの両側端部には上下に延びるリブ１Ｂ１８を一対形成しており、各リブ１Ｂ１８の上端部に、リブ１Ｂ１８の突出寸法よりも大きく外方へ突出させた突部１Ｂ１９を形成している。また、第１ホルダ要素１Ｂ１の底壁１Ｂ１２には、その幅方向に沿って延び、且つこの底壁１Ｂ１２肉厚を貫通させるスリット１Ｂ１２ｓを前端部に形成している。そして、この底壁１Ｂ１２のスリット１Ｂ１２ｓよりも後端部寄りの部位における幅方向中央部に、底面視半円形状をなす下向突起１Ｂ１２ｔを下方へ突出させて形成している。
【００３１】
図５（ｂ）、図６（ｂ）及び図７（ｂ）に示すように、第２ホルダ要素１Ｂ２における内面１Ｂ２１ａの中央部には、第１ホルダ要素１Ｂ１の起立壁１Ｂ１１に向けて略水平方向に突出する円柱状の円柱突部１Ｂ２４を形成している。この円柱突部１Ｂ２４は、第１ホルダ要素１Ｂ１に形成した円筒突部１Ｂ１４に嵌め込まれローラ１Ａの回転軸として機能するものであり、外径寸法を第１ホルダ要素１Ｂ１の円筒突部１Ｂ１４の内径より若干小さくしている。また、この円柱突部１Ｂ２４の下方、すなわち起立壁１Ｂ２１から第１ホルダ要素１Ｂ１側へ突出させた側壁１Ｂ２３の下端部には、第１ホルダ要素１Ｂ１に形成した係合孔１Ｂ１５に対応する係合突起１Ｂ２５を２つ形成している。また、第２ホルダ要素１Ｂ２の底壁１Ｂ２２には、第１ホルダ要素１Ｂ１と同様に、その幅方向に沿って延び、且つこの底壁１Ｂ２２肉厚を貫通させたスリット１Ｂ２２ｓを前端部に形成している。そして、この底壁１Ｂ２２のスリット１Ｂ２２ｓよりも後端部寄りの部位における幅方向中央部に、底面視半円形状をなす下向突起１Ｂ２２ｔを下方へ突出させて形成している。
【００３２】
図８（ａ）にスライド部材１の上側視の斜視図、同（ｂ）にスライド部材１の下側視の斜視図を示すように、これら第１ホルダ要素１Ｂ１と第２ホルダ要素１Ｂ２とローラ１Ａとからなる一体のスライド部材１の組み立ては、次のようにしてなされる。すなわち図９（スライド部材１の分解斜視図）、図１０（スライド部材１の縦断面図）及び図１１｛（ａ）；スライド部材１の正面図、（ｂ）；スライド部材１の側面図、（ｃ）；スライド部材１の底面図｝に示すように、第１ホルダ要素１Ｂ１の円筒突部１Ｂ１４をローラ１Ａの貫通孔１Ａｈに挿入しておき、次に、第２ホルダ要素１Ｂ２の円柱突部１Ｂ２４と係合突起１Ｂ２５をそれぞれ対応する第１ホルダ要素１Ｂ１の円筒突部１Ｂ１４の中空内部と係合孔１Ｂ１５へ挿入する。これにより、第１ホルダ要素１Ｂ１及び第２ホルダ要素１Ｂ２の側壁１Ｂ１３、１Ｂ２３同士、底壁１Ｂ１２、１Ｂ２２同士が当接し合い、ローラ１Ａが円筒突部１Ｂ１４を回転軸として回転可能な状態でスライド部材１の組み立てが完了する。尚、第１ホルダ要素１Ｂ１及び第２ホルダ要素１Ｂ２の当接面を接着剤等で接合しておいてもよい。また、このように組み立てた状態で、第１要素の底壁１Ｂ１２及び第２ホルダ要素の底壁１Ｂ２２とから構成されるホルダ１Ｂの底壁には、前後一対のスリット１Ｂ１２ｓ、１Ｂ２２ｓ間に、上下方向に弾性変形可能な見掛け上一体の板バネ部１Ｂｘが形成される。また、この板バネ部１Ｂｘにおいては、各下向突起１Ｂ１２ｔ、１Ｂ２２ｔ同士が接合される結果、見掛け上一体の円柱形状をなす突起部１Ｂｔが下方へ突出した状態で形成されていることになる。さらにスライド部材１の上端部側では、ホルダ１Ｂ上端からローラ１Ａの大径部１Ａ１上側約３分の１、且つ小径部１Ａ２の上側約４分の１を上方へ突出させている。
【００３３】
図１２及び図１３に示すように、このようなスライド部材１を取り付けるための第２引き戸Ｄ２側の構成は以下のようなものである。なお、図１２及び図１３においては、第１引き戸Ｄ１を省略している。第２引き戸Ｄ２は、適宜箇所を折り曲げて形成した１枚の矩形金属板材を主体とするものであるが、特にその金属板の上端部と両側端部を後方へ略直角に折り曲げることによって上壁Ｄ２１と側壁Ｄ２２とを形成している。この上壁Ｄ２１の両側側端部にはスライド部材１との干渉を避けるため切り欠き部Ｄ２１ａを形成している。側壁Ｄ２２の上端部もスライド部材１の脱着作業のために一部切り欠いている。更に、第２引き戸Ｄ２の前壁Ｄ２３の裏面Ｄ２３ａにおける上端部には、スライド部材１を取り付けるための取付部材３を設けいてる。この取付部材３は、第２引き戸Ｄ２の前面板となる前壁Ｄ２３と略同一の幅の１枚の金属板を幅方向に沿って２カ所で折り曲げた側面視アングル状をなすものであって、下側の起立片３１を前壁Ｄ２３の裏面Ｄ２３ａに当接した状態で溶接などにより取り付けられる。そして、上側の起立片３２の上端は、上壁Ｄ２１と略同一高さ位置に設定している。また、上側の起立片３２の両端部においては、第１ホルダ要素１Ｂ１の起立壁１Ｂ１１の外面１Ｂ１１ｂに形成した突部１Ｂ１９に対応する１対の位置決め孔３２ａを上方に開放させてそれぞれ形成している。そして、上下の起立片３１、３２を繋いでいる水平片３３上にホルダ１Ｂの底壁に形成された突部１Ｂｔを載せた状態で、スライド部材１の前記突部１Ｂ１９を位置決め孔３２ａに挿入することによって、スライド部材１の幅方向への位置決めを行っている。更に、係合爪１Ｂ１６を挿入させる開口部３２ｂを上側の起立片３２に左右両側端部に形成している。前記開口部３２ｂは、係合爪１Ｂ１６より一回り大きく設定しており、スライド部材１を水平片３３に載せた状態では、係合爪１Ｂ１６が開口部３２ｂに遊嵌された状態となっている。前記のように組み立てられることによって、第２引き戸Ｄ２の上端からは、スライド部材１におけるローラ１Ａの大径部１Ａ１及び小径部１Ａ２の上端が一部突出した状態となる。
【００３４】
第２引き戸Ｄ２の下端側については、前記上壁Ｄ２１のような底壁は形成せずに、切り放してある。また、上述した上端部側と同様に、側壁Ｄ２２の上端部もスライド部材１の脱着作業のために一部切り欠いている。そして、第２引き戸Ｄ２の前壁Ｄ２３の裏面Ｄ２３ａにおける下端部には、スライド部材１を取り付けるための上端部と同一の取付部材３の上下を逆にして設けている。また、上下逆向けに当接された取付部材３の下側の起立片３１の下端は、前壁Ｄ２３と略同一高さ位置に設定している。しかして、スライド部材１を上端部への取付と同様に行う。また、第２引き戸Ｄ２の下端からもスライド部材１のローラ１Ａの大径部１Ａ１及び小径部１Ａ２の下端が突出した状態をなす。なお、詳述はしないが、第１引き戸Ｄ１へのスライド部材１の取付態様は、第２引き戸Ｄ２の場合と同様である。
【００３５】
次に本実施形態の作用について説明する。
【００３６】
図１３及び図１４（ａ）に模式的な縦断面を示すように、収納家具本体Ｒ０の天板Ｒ２に重量物を置いていない時の第１引き戸Ｄ１及び第２引き戸Ｄ２は、上側レール部２のレール溝２１の下向面２１ａとスライド部材１のローラ１Ａの大径部１Ａ１が軽く接触した状態か、全く接触していない状態で左右方向に軽くスライドする。しかし、同図（ｂ）及び図１５に模式的に示すように、天板Ｒ２に重量物を置いた状態では、天板Ｒ２が下方に若干撓むことになる。すると、レール溝２１の下向面２１ａが大径部１Ａ１に上方から当接するか、あるいは、レール部２の下面２２が小径部１Ａ２に上方から当接して、スライド部材１の全体が下方に押さえつけられる。そうすると、ホルダ１Ｂの底壁の突起部１Ｂｔが取付部材３の水平片３３に強く当接する結果、板バネ部１Ｂｘが、弾性変形により上方へ湾曲してローラ１Ａとレール部２との相対位置関係を上述した天板Ｒ２に大きな上載荷重がない場合と略同様の相対位置関係に保つようになる。すなわち、この板バネ部１Ｂｘとホルダ１Ｂの底壁に設けられた突部１Ｂｔが相対位置関係を保ち、相対位置手段として機能することとなる。この時、ホルダ１Ｂの係合爪１Ｂ１６の下向きテーパー面１Ｂ１６ａが、開口部３２ｂの上縁に当接するため、係合爪１Ｂ１６が角孔Ｂ１７内へ押し込まれる結果、板バネ部１Ｂｘの撓みに伴うスライド部材１の沈み混み動作が許容される。また、板バネ部１Ｂｘの延出方向は、各引き戸Ｄ１、Ｄ２の幅方向と同一方向、換言すればローラ１Ａの回転による進行方向と同一方向と合致させているため、引き戸Ｄ１、Ｄ２の上端の如き小さく限られたスペース内でもコンパクトな構成で有効に弾性力とそれに基づく撓み量が得られる。さらに、突起部１Ｂｔは見掛け上一体をなしているが、実際には各ホルダ要素１Ｂ１、１Ｂ２に個別に設けた下向突起１Ｂ１２ｔ、１Ｂ２２ｔから構成したものであるので、各下向突起１Ｂ１２ｔ、１Ｂ２２ｔは各々単独であっても突起部１Ｂｔ全体と同様に作用する。尚、下側のスライド部材１は、第１引き戸Ｄ１、第２引き戸Ｄ２の自重によって常に下側下方へ押さえつけられることとなる。すなわち、このようなスライド部材１は、ホルダ１Ｂに保持されたローラ１Ａとレール部２との相対位置関係を略一定に維持することが出来るものである。
【００３７】
以上のように、本実実施形態におけるスライド部材１は、収納家具本体Ｒ０に設けられたレール部２に沿って第１引き戸Ｄ１及び第２引き戸Ｄ２をスライド移動させるために第１引き戸Ｄ１及び第２引き戸Ｄ２に設けたものであるが、このスライド部材１は相対位置維持手段として機能する構成を有しているので、天板Ｒ２に重量物等を載せた場合の荷重や自重等による天板Ｒ２の撓みが生じても相対位置関係を略一定に保つことが出来るものであるため、常に第１引き戸Ｄ１及び第２引き戸Ｄ２の好適なスライド動作を確保することができる。
【００３８】
また、スライド部材１は、ローラ１Ａとホルダ１Ｂとから構成したものでありこのホルダ１Ｂには、弾性変形可能な板バネ部１Ｂｘを形成し、その弾性変形を利用してホルダ１Ｂに相対位置維持手段としての機能を付与している。より具体的には、板バネ部１Ｂｘに第１引き戸Ｄ１及び第２引き戸Ｄ２に取り付けられた取付部材３に当接する突起部１Ｂｔを形成しているので、天板Ｒ２に大きな荷重が作用すると、この突起部１Ｂｘが取付部材３に強く当接することによって、板バネ部１Ｂｘの弾性変形が容易に行われ、ローラ１Ａとレール部２との相対位置関係が略一定に保たれ、第１引き戸Ｄ１及び第２引き戸Ｄ２のスムーズな移動を維持することができる。
【００３９】
そして、第１ホルダ要素１Ｂ１の起立壁１Ｂ１１の外面１Ｂ１１ｂに形成されている係合爪１Ｂ１６は、取付部材３に設けられた開口部３２ｂに緩く嵌め込んだ状態で係合させてあるので、天板Ｒ２からの撓みが生ずると、前記係合爪１Ｂ１６の下向きテーパー面１Ｂ１６ａが開口部３２ｂに押され、第１ホルダ要素１Ｂ１の起立壁１Ｂ１１との連結部分の弾性変形によって角孔１Ｂ１７内へ押し込まれることにより後退するので、それに伴って、上側のスライド部材１が取付部材３側に降下可能となる。従って、ホルダ１Ｂの底壁にある突部１Ｂｔが取付部材３の水平片３３に強く当接した場合、板バネ部１Ｂｘが弾性変形することにより、レール部２が下方へ湾曲するのに伴って、上側のスライド部材１が、ローラ１Ａとレール部２との上下方向の位置関係を維持したまま降下するので、第１引き戸Ｄ１及び第２引き戸Ｄ２のスムーズなスライド動作が確保される。
【００４０】
また、ホルダ１Ｂには、レール部２のレール溝２１に沿って転動するローラ１Ａを保持させているので、天板Ｒ２に作用する荷重が作用した場合であっても、第１引き戸Ｄ１及び第２引き戸Ｄ２の円滑なスライド移動が確保される。
【００４１】
そして、収納家具本体Ｒ０の天板Ｒ２の下面側前端部及び底板Ｒ３の上面側前端部の幅方向全域に同一構成のレール部２を配置し、さらに第１引き戸Ｄ１及び第２引き戸Ｄ２の各上端部及び各下端部に何れも同一構成のスライド部材１を配置しているため、部材の共有化とコストダウンを図ると共に、スライド部材１の取り付け作業の迅速化を図ることができる。
【００４２】
尚、本発明は上述した実施形態に限られるものではない。例えばスライド部材には、ローラを備えたもの以外に、レール部に対して滑らかに相対移動することができる平滑なブロック状のもの、板状のもの、突起状のものなど、種々のものを適用することができる。また、スライド部材は、必ずしもスライダとホルダとに分かれたものでなくても構わない。さらに、スライド部材とレール部材の配置位置は、相互に逆にして、スライド部材を収納家具本体側に設けレール部材を引き戸側に設けてもよい。
【００４３】
さらにまた、本発明のスライド部材は、収納家具の引き戸にのみ適用されるものではなく、居室や建物の出入口に設けられる固定物たるドア枠を開閉する引き戸など、あらゆる引き戸のスライド移動に適用することができるものである。その他、各部の具体的構成についても上記実施形態に限られるものではなく、本発明の趣旨を逸脱しない範囲で種々変形が可能である。

BACKGROUND OF THE INVENTION
The present invention relates to a slide member capable of suitably sliding a sliding door, a sliding door using the sliding member, and storage furniture.
[0002]
[Prior art]
Conventionally, various storage furniture provided with a sliding sliding door in order to open and close the storage space of the storage furniture body has been considered. In such storage furniture, a rail portion extending along the width direction of the sliding door is formed at the upper edge portion or the lower edge portion or both of the opening portion of the storage furniture main body, and on the sliding door corresponding to the rail portion. In general, a slide member provided with a rollable roller or the like is provided (for example, see Patent Document 1). For example, the slide member includes a holder fixed to the sliding door and a roller pivotally supported by the holder.
[0003]

Japanese Patent Application 2002-250571 (FIG. 3 etc.)
[0004]
[Problems to be solved by the invention]
However, in the conventional storage furniture as described above, when a relatively heavy object is placed on the top plate, the top plate bends downward due to the load of the placed object, and the top plate is the upper end of the sliding door. The part side roller is strongly pressed downward, and the rotation of the roller is obstructed. In other words, the roller that is pivotally supported by the holder in order to smoothly open and close the sliding door cannot perform its function. Such a problem does not occur only in this type of storage furniture, but is common to sliding doors such as sliding door type sliding doors provided at entrances and the like of living rooms, and is also common to sliding members including rollers. That is, if the rail portion provided on the upper end side of the door frame for guiding the sliding movement of the sliding door is long, the rail portion tends to bend in the longitudinal direction due to the weight of the rail portion. Since the portion strongly presses the slide member provided at the upper end of the sliding door, there is a risk that the opening and closing of the sliding door may be obstructed.
[0005]
Therefore, in view of the above problems, the present invention provides a sliding member that does not hinder the opening and closing of the sliding door even when the top plate of the storage furniture is overloaded, and an excellent sliding door using this sliding member. In addition, the main object is to provide storage furniture, and further, it is an object to provide a suitable sliding member applicable not only to storage furniture but also to sliding doors in general.
[0006]
[Means for Solving the Problems]
That is, the slide member according to the present invention opens the storage space at the upper end portion of the sliding door or the lower surface of the top plate of the storage furniture body when the sliding door is slidably provided with respect to the storage furniture body provided with the top plate. Relative position maintaining means that is attached to any one of the upper edge portions of the opening and that can maintain the relative positional relationship with respect to the rail portion provided on either the upper edge of the opening or the sliding door substantially constant. It is characterized by comprising.
[0007]
With the slide member having such a configuration, even when a heavy object is placed on the top plate or when the top plate is bent downward, the slide member is always kept relative to the rail portion by the relative position maintaining means. Since a substantially constant positional relationship, in particular, a vertical positional relationship is maintained, the sliding movement of the sliding member relative to the rail portion is maintained in a smooth state. As a result, the sliding door provided with such a sliding member at the upper end portion Always opens and closes smoothly with respect to the storage furniture body. In addition, a slide member may be provided in an opening upper edge part among the opening parts of a storage furniture main body, and may be provided in the upper end part of a sliding door. On the other hand, the rail portion is provided on a member opposite to the slide member. And this invention can implement | achieve the smooth opening / closing operation | movement of a sliding door by adding the structure as described below.
[0008]
First, the slide member includes a slider that is guided to slide by the rail portion, and a holder that holds the slider and is attached to the upper edge of the opening of the sliding door or the storage furniture body. Forming the relative position maintaining means that keeps the relative position with respect to the rail portion substantially constant, and sharing the function between a slider that mainly performs sliding movement and a holder that maintains the positional relationship with respect to the rail portion while holding the slider. Thus, the configuration can be simplified.
[0009]
In particular, those having a simple structure as the relative position maintaining means include those utilizing elastic deformation. Specifically, if the relative position maintaining means is constituted by an elastically deformable leaf spring portion formed on the holder, the holder itself can be provided with a function as an elastic body, so that the coil spring is separate from the holder. It is no longer necessary to use an elastic member such as a rubber elastic body, and the simplification of the structure can be further improved. Here, the leaf spring portion includes one bent toward the non-rail portion side.
[0010]
Further, in the case where the leaf spring portion is a flat plate, a protruding portion that protrudes toward the anti-rail portion is formed on the leaf spring portion, and the sliding door or the storage furniture main body whose protrusion portion is on the anti-rail portion side is formed. It is desirable that the leaf spring portion is elastically deformed by contacting the upper edge portion of the opening.
[0011]
As a configuration for easily forming such a leaf spring part in the holder, a slit is formed on the opposing wall part facing the rail part in the holder, and a portion sandwiched between these slits is defined as the leaf spring. Part.
[0012]
In addition, in order to make the holder play an appropriate role without hindering the main function of the leaf spring portion to maintain the relative positional relationship with respect to the rail portion of the slider, a sliding door is provided at a position different from the leaf spring portion in the holder. Or it is good to form the attachment part for fitting to the opening edge part of a storage furniture main body, ie, fitting with a predetermined clearance.
[0013]
As a suitable slider, a roller supported by a holder so as to be able to roll along the rail portion can be cited.
[0014]
In short, the sliding door in the storage furniture according to the present invention having the slider configured as described above is a rail portion arranged at the upper edge of the opening among the openings that open the storage space of the storage furniture body including the top plate. The sliding door is slidably provided to open and close the storage space, and the above-mentioned slide member is arranged at the upper end facing the rail portion, so that a smooth opening and closing operation can be performed with a simple configuration. Can be realized.
[0015]
Furthermore, when the rail part of the same structure as the opening upper edge part is arranged also in the opening lower edge part in the storage furniture main body, the slide member on the upper end part side is arranged on the lower end part facing the rail part in the opening lower edge part. If the slide members having the same configuration are arranged, the members can be shared, the cost can be reduced, and the slider mounting operation can be speeded up. In addition, on the lower end part side of the sliding door, the relative position maintaining means in the slide member on the lower end part side always acts by the weight of the sliding door itself.
[0016]
The storage furniture according to the present invention including the slider having the above-described configuration includes a storage furniture body including a top plate and a predetermined storage space, and an opening that opens the storage space to open and close the storage space. The sliding furniture is provided, and in the storage furniture main body, the rail portion is provided on either the upper edge of the opening or the upper end of the sliding door in the opening, and the above-described slide member is provided on the other. Therefore, it is possible to smoothly open and close the sliding door with respect to the storage furniture body regardless of the presence or absence of an overload on the top board.
[0017]
Further, in order to improve the commonality of members, cost reduction, and convenience of assembly work in this storage furniture, the opening furniture has a lower edge or a sliding door at the lower edge of the opening. A rail portion having the same configuration as the rail portion may be provided, and a slide member having the same configuration as the slide member may be provided on the other side.
[0018]
In addition, this invention is applicable not only to the sliding member applied to the sliding door of the storage furniture mentioned above but general sliding doors, such as a sliding door. In the present invention having the configuration for that purpose, when the sliding door is slidably provided with respect to the fixed object, the sliding door is attached to either the fixed object or the sliding door, and is attached to either the fixed object or the sliding door. Relative position maintaining means that can keep the relative positional relationship with respect to the provided rail portion substantially constant is provided. For example, when this sliding member is applied to a sliding door provided at a doorway of a living room or a building, even if the rail portion provided on the door frame, which is a fixed object, is bent due to its own weight, the relative position maintaining means functions correspondingly. Since the relative positional relationship of the slide member with respect to the rail portion is kept substantially constant, it is possible to maintain a suitable and smooth opening / closing operation of the sliding door.

Yes. The protrusion 1B19 of the slide member 1 is inserted into the positioning hole 32a in a state where the protrusion 1Bt formed on the bottom wall of the holder 1B is placed on the horizontal piece 33 that connects the upper and lower standing pieces 31 and 32. By doing so, the slide member 1 is positioned in the width direction. Furthermore, the opening part 32b which inserts the engaging nail | claw 1B16 is formed in the upright piece 32 in the right-and-left both ends. The opening 32b is set to be slightly larger than the engaging claw 1B16. When the slide member 1 is placed on the horizontal piece 33, the engaging claw 1B16 is loosely fitted in the opening 32b. . By assembling as described above, the upper ends of the large diameter portion 1A1 and the small diameter portion 1A2 of the roller 1A in the slide member 1 are partially protruded from the upper end of the second sliding door D2.
[0034]
About the lower end side of the 2nd sliding door D2, the bottom wall like the said upper wall D21 is not formed, but is cut off. Further, similarly to the above-described upper end side, the upper end portion of the side wall D22 is partially cut away for the detaching operation of the slide member 1. And the upper and lower sides of the attachment member 3 same as the upper end part for attaching the slide member 1 are provided in the lower end part in the back surface D23a of the front wall D23 of the 2nd sliding door D2. Moreover, the lower end of the upright piece 31 on the lower side of the mounting member 3 that is abutted in the upside down direction is set at a substantially same height position as the front wall D23. Therefore, the slide member 1 is performed in the same manner as the attachment to the upper end. Further, the lower end of the large-diameter portion 1A1 and the small-diameter portion 1A2 of the roller 1A of the slide member 1 also protrudes from the lower end of the second sliding door D2. Although not described in detail, the manner of attaching the slide member 1 to the first sliding door D1 is the same as that of the second sliding door D2.
[0035]
Next, the operation of this embodiment will be described.
[0036]
13 and 14A, the first sliding door D1 and the second sliding door D2 when the heavy object is not placed on the top plate R2 of the storage furniture body R0 are arranged on the upper rail portion. The lower surface 21a of the second rail groove 21 and the large-diameter portion 1A1 of the roller 1A of the slide member 1 lightly slide in the left-right direction in a state where they are in light contact or not at all. However, as schematically shown in FIG. 15B and FIG. 15, in a state where a heavy object is placed on the top plate R2, the top plate R2 is slightly bent downward. Then, the downward surface 21a of the rail groove 21 abuts on the large diameter portion 1A1 from above, or the lower surface 22 of the rail portion 2 abuts on the small diameter portion 1A2 from above, and the entire slide member 1 is pressed downward. It is done. Then, as a result of the protrusion 1Bt on the bottom wall of the holder 1B strongly contacting the horizontal piece 33 of the mounting member 3, the leaf spring portion 1Bx is bent upward due to elastic deformation and the relative positional relationship between the roller 1A and the rail portion 2 is reached. Is maintained in the same relative positional relationship as in the case where there is no large overload on the top plate R2 described above. That is, the leaf spring portion 1Bx and the protrusion 1Bt provided on the bottom wall of the holder 1B maintain a relative positional relationship and function as relative position means. At this time, since the downward tapered surface 1B16a of the engaging claw 1B16 of the holder 1B abuts on the upper edge of the opening 32b, the engaging claw 1B16 is pushed into the square hole B17, resulting in bending of the leaf spring portion 1Bx. The sinking operation of the slide member 1 is allowed. Further, the extension direction of the leaf spring portion 1Bx is the same as the width direction of the sliding doors D1 and D2, in other words, the same direction as the traveling direction due to the rotation of the roller 1A, so the upper ends of the sliding doors D1 and D2 Even in such a small and limited space, the elastic force and the deflection amount based on the elastic force can be obtained effectively with a compact configuration. Further, although the protrusion 1Bt is apparently integrated, it is actually composed of the downward protrusions 1B12t and 1B22t provided individually on the holder elements 1B1 and 1B2, respectively. Therefore, the downward protrusions 1B12t and 1B22t are provided. Even if each is independent, it acts in the same manner as the entire protrusion 1Bt. Note that the lower slide member 1 is always pressed downward by the weight of the first sliding door D1 and the second sliding door D2. That is, such a slide member 1 can maintain the relative positional relationship between the roller 1A held by the holder 1B and the rail portion 2 substantially constant.
[0037]
As described above, the slide member 1 in the present embodiment has the first sliding door D1 and the first sliding door D1 to slide the first sliding door D1 and the second sliding door D2 along the rail portion 2 provided in the storage furniture body R0. Although it is provided in the two sliding doors D2, since this slide member 1 has a configuration that functions as a relative position maintaining means, the top plate due to a load or a dead weight when a heavy object or the like is placed on the top plate R2. Even if the bending of R2 occurs, the relative positional relationship can be kept substantially constant, so that a suitable sliding operation of the first sliding door D1 and the second sliding door D2 can always be ensured.
[0038]
The slide member 1 includes a roller 1A and a holder 1B. The holder 1B is formed with a leaf spring portion 1Bx that can be elastically deformed, and the relative position is maintained on the holder 1B using the elastic deformation. A function as a means is given. More specifically, since the protrusion 1Bt that contacts the attachment member 3 attached to the first sliding door D1 and the second sliding door D2 is formed on the leaf spring portion 1Bx, when a large load acts on the top plate R2, When the projection 1Bx strongly contacts the mounting member 3, the leaf spring portion 1Bx is easily elastically deformed, the relative positional relationship between the roller 1A and the rail portion 2 is maintained substantially constant, and the first sliding door D1 is maintained. And the smooth movement of the 2nd sliding door D2 can be maintained.
[0039]
The engaging claw 1B16 formed on the outer surface 1B11b of the upright wall 1B11 of the first holder element 1B1 is engaged with the opening 32b provided in the mounting member 3 in a loosely fitted state. When the bending from the plate R2 occurs, the downward tapered surface 1B16a of the engaging claw 1B16 is pushed by the opening 32b, and is pushed into the square hole 1B17 by elastic deformation of the connecting portion with the upright wall 1B11 of the first holder element 1B1. Accordingly, the upper slide member 1 can be lowered to the mounting member 3 side. Therefore, when the protrusion 1Bt on the bottom wall of the holder 1B strongly contacts the horizontal piece 33 of the mounting member 3, the leaf spring portion 1Bx is elastically deformed, so that the rail portion 2 is bent downward. Since the upper slide member 1 descends while maintaining the vertical positional relationship between the roller 1A and the rail portion 2, smooth sliding operation of the first sliding door D1 and the second sliding door D2 is ensured.
[0040]
Further, since the roller 1A that rolls along the rail groove 21 of the rail portion 2 is held on the holder 1B, even if a load acting on the top plate R2 is applied, the first sliding door D1 and Smooth sliding movement of the second sliding door D2 is ensured.
[0041]
And the rail part 2 of the same structure is arrange | positioned in the width direction whole region of the lower surface side front end part of top plate R2 of storage furniture main body R0, and the upper surface side front end part of bottom plate R3, and also each of 1st sliding door D1 and 2nd sliding door D2 Since the slide member 1 having the same configuration is disposed at the upper end portion and the lower end portions, the member can be shared and the cost can be reduced, and the mounting operation of the slide member 1 can be speeded up.
[0042]
The present invention is not limited to the embodiment described above. For example, various slide members, such as those with a smooth block that can move smoothly relative to the rail part, plates, and protrusions, can be used in addition to those with rollers. can do. Further, the slide member is not necessarily divided into the slider and the holder. Furthermore, the arrangement positions of the slide member and the rail member may be reversed, and the slide member may be provided on the storage furniture main body side and the rail member may be provided on the sliding door side.
[0043]
Furthermore, the sliding member of the present invention is not only applied to the sliding door of the storage furniture, but is applied to the sliding movement of all sliding doors such as a sliding door that opens and closes a door frame that is a fixed object provided at the entrance of a living room or a building. It is something that can be done.
