Description

【０００１】
【発明の属する技術分野】
本発明は、たとえば引違い障子等において、障子を円滑に開閉できるように、上下方向調整機構および室内外方向調整機構を同時に兼ね備えた二次元調整戸車に関する。
【０００２】
【従来の技術】
従来より、片引き・引き違い形式の戸または障子等に対しては、開閉時の滑り抵抗を軽減し開閉操作を円滑化するために、その下端面に対して戸車が設けられている。
かかる戸車に関しては、従来より建付け後に戸または障子等を上下方向に調整し得るようにしたものが提案されている。
その一例を紹介すると、図３２に示されるように、ローラ５０を内枠５１と外枠５２とからなる保持枠５３により保持し、前記外枠５２から貫通状態で設けられた上下方向調整ネジ５４を前記内枠５１に対して螺合させ、この上下方向調整ネジ５４を回して内枠５１をレール方向にスライドさせることにより、戸または障子を上下方向に調整可能としている。具体的には、前記内枠５１にローラ５０のローラ軸５０ａを保持するための斜め方向溝５１ａを形成するとともに、外枠５２にローラ軸５０ａを保持する鉛直方向溝５２ａを形成し、前記ローラ５０を前記内枠５１に装着した状態で外枠５２を嵌め込むことにより、これら両溝５１ａ、５２ａの交差部によってローラ軸５０ａを保持するように構成し、前記上下方向調整ネジ５４を回して前記内枠５１をレール方向にスライドさせると、内枠５１の斜め方向溝５１ａにガイドされてローラ５０が上下方向に移動し、相対的に障子または戸全体が上下方向に移動調整可能となっている。
【０００３】
【発明が解決しようとする課題】
すなわち、従来より提供されている戸車は、前述のように鴨居等に対する係合具合を調整するため、上下方向には調整可能となっているものの、戸または障子等の建付け、建込み時の調整不具合や、経時的に生ずる障子自体の反り・変形等により、内障子と外障子との召合せ部等が接触したり、衝突したりする不具合が生じたとしても、室内外方向の調整は一切できない構造となっている。
【０００４】
そこで、本発明の主たる課題は、召合せ部等の接触・衝突を無くして障子または戸を円滑に開閉し得るように、室内外方向にも位置調整可能とした二次元調整戸車を提供することにある。
【０００５】
【課題を解決するための手段】
前記課題を解決するために本発明は、外ケース内に収容された、ローラおよびその保持枠からなる戸車本体が、略上下方向に沿う方向に位置調整可能に支持されているとともに、前記外ケース内において前記室内外方向にスライド用間隙を有する状態で収容され室内外方向にも位置調整可能に支持された二次元調整戸車であって、
前記戸車本体の保持枠を貫いて外ケースの側壁間に横架された室内外方向配置の支軸によって前記戸車本体を回動可能に支持するとともに、前記保持枠の背面壁に対して直接または間接的に先端が当接する上下方向調整ネジを設け、この上下方向調整ネジの前後進調整に伴う前記戸車本体の回動位置調整により前記戸車本体を略上下方向に位置調整可能とし、
前記支軸に対して、前記戸車本体と係合して一体的にスライド動作するとともに、縦方向の長孔溝を有する作動ブロック片を設ける一方、レール方向の回転中心軸をもって回転自在とされる室内外方向調整部材を設け、この室内外方向調整部材の作動ブロック片側の面に前記回転中心軸から偏心した位置に前記作動ブロック片の縦方向長孔溝に係合する偏心突起を設け、前記室内外方向調整部材の回転調整により前記作動ブロック片を支軸方向にスライドさせ、前記戸車本体を室内外方向に位置調整可能としたことを特徴とするものである。
【０００６】
この場合に、前記室内外方向調整部材は本体部分の周面に正多角形状部を有し、両側に配された弾発部材が前記正多角形状部の両側面へ夫々押圧接触することにより前記室内外方向調整部材の固定保持を行うようにするのが望ましい。また、前記弾発部材は、前記外ケースの側壁に離間を空けて一対の縦方向スリットを形成するとともに、これら両縦方向スリットに挟まれた離間部の上下端の一方を縁切りすることにより形成した片持ち梁状の弾発片とすることができる。
【０００７】
また、前記室内外方向調整部材と外ケースとの当接接触面部において、一方の側に噛合爪を形成するとともに、他方の側に周方向に亘って前記噛合爪が係合する噛合爪受け部を形成し、かつ前記室内外方向調整部材を戸車本体側付勢して設けてある構造とすることもできる。
【０００８】
一方、前記作動ブロック片から延在して前記保持枠の一部に係止し、戸車本体を外ケース内に収容保持する係止用舌片を形成することにより、建て付け時に戸車本体が垂れ下がるのを防止できるため建て付け作業が容易となる。また、前記保持枠の背面壁と上下方向調整ネジ先端との間に、下端側の室内外方向回動軸をもって回動自在とされる保持枠押え板を介在させることにより、保持枠を偏圧することなく均一に押圧保持できるようになる。
【０００９】
本発明においては、戸または障子等の建付け、建込み時に内・外の戸・障子等の召合せ部が接触したり、または衝突する場合などは、ドライバーなどの手工具類により、前記室内外方向調整部材を回転させることにより、戸車本体を室内外方向に位置調整できるため、かかる不具合を簡単に修正することができる。また、経時変化により、その後に戸または障子等に反りや変形が生じ、障子同士が接触するようになった場合でも、居住者が簡単にこれを修正することができる。
【００１０】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて詳述する。
〔第１実施形態例〕
図１は本発明に係る二次元調整戸車１の側面図、図２は図１のII−II線矢視図、図３は図１のIII −III 線矢視図、図４は分解図、図５は組立後の縦断面図である。
本発明に係る二次元調整戸車（以下、単に調整戸車という。）１は、主に外ケース２と、ローラ５およびローラ保持枠４からなる戸車本体３と、前記戸車本体３を外ケース２に対して回動可能に支持する支軸９と、前記ローラ保持枠４の背面壁に対して先端が当接するように配置され、前後進調整により戸車本体３の上下方向調整を行うための上下方向調整ネジ８と、前記戸車本体３と係合しながら前記支軸９に挿通支持され戸車本体３と共に室内外方向にスライド動作する作動ブロック片６と、この作動ブロック片６を室内外方向にスライド移動させるための室内外方向調整部材７とにより構成される。
【００１１】
前記外ケース２は、詳細には図６〜図９に示されるように、ポリアミド等の樹脂により製造された型成形品であり、下側に開口する戸車本体３収容のための内空部２ａを有し、障子の側端面側（以下、障子端側という。）の側壁部に上下方向調整ネジ８の設置部、および室内外方向調整部材７の設置部を有する。また、室内外方向に対面する両側壁には戸車本体３を回動支持する支軸９のための保持孔１９、１９が形成され、障子端側の上部および他端側の下面には障子への取付けのためにビス孔を有する突出片１１、１２が形成されている。
【００１２】
さらに詳述すると、外ケース２の障子端側の側壁上部位置には上下方向調整ネジ８の取付け孔１３（以下、ネジ取付け孔という。）と、前記上下方向調整ネジ８に螺合されるナット１０のためのナット嵌設孔１４とが水平方向に連続して形成されている。具体的には、前記ネジ取付け孔１３は側方に開口するやや大径のネジ頭部孔１３ａと、このネジ頭部孔１３ａの底壁に形成されたネジ軸孔１３ｂとからなり、前記ネジ軸孔１３ｂの中間位置に側方に開口するナット１０の嵌設孔１４が形成されており、図４に示されるように、前記ナット嵌設孔１４にナット１０を装設した状態で上下方向調整ネジ８を螺入することにより設置する。また、上下方向調整ネジ８の先端部相当位置には側方に開口する窓１６が形成されており、前記上下方向調整ネジ８を螺設した後、前記窓１６からペンチ等を挿入して上下方向調整ネジ８のネジ山を潰すことにより抜け止め処理が行えるようにしてある。
【００１３】
また、前記ネジ取付け孔１３の下方位置には、室内外方向調整部材７の取付け孔１７（以下、カム取付け孔という。）が形成されているとともに、このカム取付け孔１７の隣接位置には側壁に離間を空けて一対の縦方向スリットを形成するとともに、これら両縦方向スリットに挟まれた離間部の上下端の一方、本例では上端を縁切りすることにより、側壁のそれぞれに片持ち梁状の弾発片１８、１８が形成されている。
【００１４】
一方、前記室内外方向調整部材７は、図４、図１４および図１５に示されるように、外ケース２の前記カム取付け孔１７に対して嵌合する嵌合頭部２６と、外ケース２の弾発片１８、１８と接触係合する六角形状部２７と、回転中心軸Ｌから距離Ｓだけ偏心した位置に設けられた偏心突起２８とから構成されており、前記嵌合頭部２６が前記カム取付け孔１７に嵌合した状態で取り付けられる。そして、図１６に示されるように、前記外ケース２の弾発片１８、１８が前記六角形状部２７の両側面に夫々に押圧接触することにより、室内外方向調整部材７が４５°回転毎に固定保持されるようになっている。
【００１５】
次いで、前記戸車本体３は、図１０および図１１に示されるように、ローラ５と、このローラ５を回転軸２１により回転自在に支持するローラ保持枠４とからなる。前記ローラ保持枠４は、金属板の成形により略断面コ字状に加工された部材であり、前記回転軸２１の対辺側上部には、ローラ保持枠４の上面端から延在して垂下する突出片４ｃにより上下方向調整ネジ８の先端が当接するやや変断面形状の背面壁２９（本明細書では、戸車本体３が外ケース２から突出する回転方向を正方向と考えているため、その反対面側を背面側としている。）が形成されている。また、その下方側には対峙する両壁面の一部が膨出して突出部４ａが形成され、該突出部４ａに支軸９が挿通するための通孔４ｂが形成されている。
【００１６】
また、前記突出部４ａの上部位置には、両壁面から延在して左右一対の受け係止片４ｄ、４ｄが設けられ、後述の作動ブロック片６の係止用舌片２４が係止することにより、障子への組付け状態で前記戸車本体３が下方向に垂れ下がらないように保持するようになっている。
【００１７】
一方、作動ブロック片６は図１２および図１３に示されるように、ブロック本体２３と、このブロック本体２３下面よりＵ字状に延在する係止用舌片２４とからなり、前記ブロック本体２３には水平方向に貫通する支軸９が挿通される通孔２３ａが形成されているとともに、背面側上部には縦方向に長い長孔溝２５が形成されている。
【００１８】
外ケース２に対する組み込みは、図４に示されるように、作動ブロック片６を前記戸車本体３の一対の突出部４ａ、４ａの間に装入し、ローラ保持枠４の通孔４ｂと作動ブロック片６の通孔２３ａとを連続させた状態としたまま、これら戸車本体３と作動ブロック片６とを外ケース２の内空部２ａに装入し、外ケース２の側部から支軸９を前記通孔４ｂ、通孔２３ａを通して挿通し、対壁面側で先端をカシメて固定する。組み込み状態では、戸車本体３は、図３に示されるように、外ケース２との間にスライド用間隙Ｈ₁、Ｈ₂を有する状態で外ケース２内に収容され、外ケース２内に横架される前記支軸９をスライド軸として室内外方向に移動自在となっている。また、図５にも示されるように、作動ブロック片６の長孔溝２５に前記室内外方向調整部材７の偏心突起２８が嵌入するとともに、作動ブロック片６の係止用舌片２４の先端が前記ローラ保持枠４の受け係止片４ｄ、４ｄに対して係止し戸車本体３が垂れ下がらないように保持している。
【００１９】
かかる調整戸車１を障子下面の凹部に装着した状態で、障子の上下方向調整を行う場合には、上下方向調整ネジ８をネジ回し等の工具を用いて左右方向の一方に回転させて戸車本体３の上下方向位置を調整する。前記上下方向調整ネジ８は位置固定のナット１０に螺入されてあり、前記上下方向調整ネジ８を右方向に回転させると、上下方向調整ネジ８は螺進し戸車本体３の背面壁２９を押し、戸車本体３を支軸９回りに回転させる。図１に示すように、戸車本体３が下方に下がれば相対的に障子が上方に移動する。また、前記上下方向調整ネジ８を左方向に回転させると、逆に戸車本体３が外ケース２内に潜り込むように回動するため障子が下方に移動される。
【００２０】
また、室内外方向調整を行う場合には、室内外方向調整部材７を左右方向の一方に回転させて行う。図１６に示されるように、作動ブロック片６の長孔溝２５に対して室内外方向調整部材７の偏心突起２８が嵌入状態にあり、室内外方向調整部材７を回転させると、前記偏心突起２８が室内外方向調整部材７の中心軸Ｌ回りに移動する。この偏心突起２８の移動に伴って作動ブロック片６が室内外方向に移動されるとともに、この作動ブロック片６と一体的にスライド動作するように係合された戸車本体３が室内外方向に移動される。室内外方向の調整可能量は、偏心突起２８の偏心量Ｓに相当し、±Ｓの距離の調整が可能である。前記室内外方向調整部材７は、外ケース２の弾発片１８との接触部形状を正六角形としてあるため、調整段階は＋Ｓ、＋１／２Ｓ、０、−１／２Ｓ、−Ｓの５段階となるが、もう少し微妙な調整を可能としたいならば、図１７に示されるように、弾発片１８に接触する部分を正１２角形状とした室内外方向調整部材７’とすることもできる。この場合には３０°回転時毎に弾発片１８によって固定保持されるようになるため、７段階の調整が可能となる。
【００２１】
なお、外ケース２の障子端側には、図２にも示されるように、上下方向調整の調整方向表示、および室内外方向調整の調整方向表示が刻印されており調整方向を間違えずに行えるようにしてあり、調整後には見栄えのためにキャップ２０が設けられるようになっている。
【００２２】
ところで、障子または戸が嵌め込まれる鴨居等の上枠においては、室内外方向に障子または戸が移動されることに伴い、レールを室内外方向に移動調整可能としている。具体的には、図１８に示されるように、鴨居３０に対してビス３１により取り付けられるレール３２のビス孔３２ａを室内外方向の所謂バカ孔としておき、レール３２を室内外方向に移動調整できるようにしている。また、図１９に示されるように、ビス配設部位にＵ字状切欠きを有する左右一対のレール半割部材３３Ａ、３３Ｂを用い、これらレール半割部材３３Ａ、３３Ｂの位置をそれぞれ調整した後、ビス３１により固定することでもよい。
【００２３】
〔第２実施形態例〕
図２０は本発明の第２例に係る二次元調整戸車１’の側面図、図２１は図２０のＡ−Ａ線矢視図、図２２は図２０のＢ−Ｂ線矢視図、図２３は分解図、図２４は組立後の縦断面図である。以下、第１例と同一機能のものについては前記第１例と同じ符号を付し説明は省略する。
本第２例に係る調整戸車１’は、主に外ケース２と、ローラ５およびローラ保持枠４からなる戸車本体３と、前記戸車本体３を外ケース２に対して回動可能に支持する支軸９と、前記ローラ保持枠４の背面壁に対して先端が当接するように配置され、前後進調整により戸車本体３の上下方向調整を行うための上下方向調整ネジ８と、前記戸車本体３と係合しながら前記支軸９に挿通支持され戸車本体３と共に室内外方向にスライド動作する作動ブロック片３４と、この作動ブロック片３４を室内外方向にスライド移動させるための室内外方向調整部材３５と、前記ローラ保持枠４の背面壁と上下方向調整ネジ８先端との間に、下端側の室内外方向回動軸をもって回動自在とされる保持枠押え板３６とにより構成される。
【００２４】
基本的構成は前記第１例と同じであるが、第１例と異符号を付した部材、具体的には作動ブロック片３４、室内外方向調整部材３５に対して若干の変更を加えてあり、新たに保持枠押え板３６を設けた点が異なる。
【００２５】
以下、第１例と異なる構成部分を中心に詳述する。
前記作動ブロック片３４は、詳細には図２８および図２９に示されるように、ブロック本体が面スリット３４ｃによって、木口側から見て前部ブロック３４Ｂと後部ブロック３４Ａとに分割され、ブロック本体の下部には支軸９が挿通される通孔３４ａが形成されている。また、ブロック本体の下部前側から１／４円弧状にローラ保持枠４に係止して外ケース２内に収容保持するための係止用舌片３４Ｃが形成されているとともに、前記後部ブロック３４Ａの木口面側（背面側）には偏心突起２８が係合する縦方向長孔溝２５が形成されている。
【００２６】
一方、前記室内外方向調整部材３５は、図３０および図３１に示されるように、外ケース２のカム取付け孔１７に対して嵌合する嵌合軸部３５Ａと、ネジ回し用溝孔が形成された操作部３５Ｂと、回転中心軸Ｌから距離Ｓだけ偏心した位置に設けられた偏心突起２８と、前記作動ブロック片３４の前部ブロック３４Ｂが係合して、該室内外方向調整部材３５全体を戸車本体３側に付勢するための受け係合片３５Ｃとから構成されている。また、前記操作部３５Ｂの戸車本体３側の面には、左右一対の噛合爪３５ａ、３５ａが形成されている。
【００２７】
他方で、外ケース２における前記室内外調整部材３５の取付け部には、図２５および図２６に示されるように、カム取付け孔１７の木口側周囲に対して、周方向に沿って多数の噛合爪受け部１７ａ，１７ａ…が形成されており、前記室内外調整部材３５の噛合爪３５ａ、３５ａが係合するようになっている。
【００２８】
組立は、図２３に示されるように、室内外方向調整部材３５をカム取付け孔１７部に装着する一方、作動ブロック片３４を前記戸車本体３の一対の突出部４ａ、４ａの間に装入し、ローラ保持枠４の通孔４ｂと作動ブロック片３４の通孔３４ａとを連続させた状態のまま、これら戸車本体３と作動ブロック片３４とを外ケース２の内空部に装入し、外ケース２の側部から支軸９を前記通孔４ｂ、通孔３４ａを通して挿通し、対壁面側で先端をカシメて固定する。組み込み状態では、図２４に示されるように、作動ブロック片３４の面スリット３４ｃの間に室内外方向調整部材３５の受け係合片３５Ｃが挿入位置し、作動ブロック片３４の前部ブロック３４Ｂの弾性力によって室内外方向調整部材３５全体が戸車本体３側に付勢されている。また、作動ブロック片３４の縦方向長孔溝２５に対して室内外方向調整部材３５の偏心突起２８が嵌入し、作動ブロック片３４の係止用舌片３４Ｃの先端幅広部３４ｄがローラ保持枠４の下面側に係止し、戸車本体３が垂れ下がらないように外ケース２内に収容保持されている。
【００２９】
したがって、室内外方向調整部材３５を左右方向の一方に回転させると、前記偏心突起２８が室内外方向調整部材３５の中心軸Ｌ回りに移動する。この偏心突起２８の移動に伴って作動ブロック片３４が室内外方向に移動されるとともに、この作動ブロック片３４と一体的にスライド動作するように係合された戸車本体３が室内外方向に移動される。
【００３０】
他方で、本第２例においては、前記ローラ保持枠４の背面壁と上下方向調整ネジ８先端との間に、下端側の室内外方向回動軸をもって回動自在とされる保持枠押え板３６を介在させている。前記保持枠押え板３６は、図２３に示されるように、方形板３６ａの一側がわ両端部に突起軸３６ｂ、３６ｂを備えたもので、取付けは外ケース２の側面に形成された装入孔２ｂより外ケース２内に装入する。前記保持枠押え板３６の設置状態時には、前記装入孔２ｂの端部に形成された軸保持部２ｃ、２ｃに対して保持枠押え板３６の突起軸３６ｂ、３６ｂが係合し、前記突起軸３６ｂ、３６ｂを回転中心軸として回動するようになっている。したがって、図２７に示されるように、上下方向調整時に、上下方向調整ネジ８を螺入させて戸車本体３を下方向に回動させた際には、共に回動してローラ保持枠４の背面を均一に押圧する。
【００３１】
なお、本第２例において、前記上下方向調整ネジ８は、第１例のようにナット部材１０を用いることなく外ケース２の本体に形成された雌ネジ孔２ｄに対して直接螺入されている。
【００３２】
【発明の効果】
以上詳説のとおり、本発明に係る調整戸車によれば、戸または障子を室内外方向にも移動調整できるため、召合せ部等の接触・衝突を無くして、常に障子または戸を円滑に開閉し得る状態に維持できる。

When the inner frame 51 is slid in the rail direction, the roller 50 is moved in the vertical direction while being guided by the oblique groove 51a of the inner frame 51, and the shoji or the entire door can be adjusted relative to the vertical direction. Yes.
[0003]
[Problems to be solved by the invention]
In other words, the doorcars provided in the past are adjustable in the vertical direction in order to adjust the degree of engagement with the duck and the like as described above, but at the time of building or installing doors or shojis, etc. Even if there is a problem that the summoning part of the inner and outer shoji comes into contact with or collides with each other due to adjustment problems or the warping / deformation of the shoji itself that occurs over time, the adjustment in the indoor / outdoor direction is possible. The structure is not possible at all.
[0004]
Thus, the main problem of the present invention is to provide a two-dimensional adjustment door that can be adjusted in the indoor and outdoor directions so that the shoji or door can be opened and closed smoothly without contact / collision of the summoning section or the like. It is in.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a door wheel main body, which is housed in an outer case and is composed of a roller and a holding frame thereof, and is supported so that the position thereof can be adjusted in a direction substantially along the vertical direction. A two-dimensional adjustment door wheel accommodated in a state having a sliding gap in the indoor / outdoor direction and supported so as to be position adjustable in the indoor / outdoor direction,
The door frame body is rotatably supported by a support shaft arranged in an indoor / outdoor direction that extends horizontally between the side walls of the outer case through the holding frame of the door frame body, and directly or against the rear wall of the holding frame. A vertical adjustment screw that indirectly contacts the tip is provided, and the position of the door body can be adjusted substantially vertically by adjusting the rotational position of the door body when the vertical adjustment screw is moved forward and backward.
The operation shaft piece having a long slot in the vertical direction is provided on the support shaft and engaged with the door main body to slide integrally with the support shaft. On the other hand, the support shaft is rotatable with a rotation center axis in the rail direction. An indoor / outdoor direction adjustment member is provided, and an eccentric protrusion that engages with a longitudinal slot in the operation block piece is provided on a surface of the operation block piece side of the indoor / outdoor direction adjustment member at a position eccentric from the rotation center axis, The operation block piece is slid in the support shaft direction by adjusting the rotation of the indoor / outdoor direction adjusting member, and the position of the door pulley body can be adjusted in the indoor / outdoor direction.
[0006]
In this case, the indoor / outdoor direction adjustment member has a regular polygonal shape portion on the peripheral surface of the main body portion, and the elastic members arranged on both sides press and contact the both side surfaces of the regular polygonal shape portion, respectively. It is desirable to fix and hold the indoor / outdoor direction adjusting member. In addition, the elastic member is formed by forming a pair of vertical slits in the side wall of the outer case so as to be spaced apart, and cutting one of the upper and lower ends of the separation portion sandwiched between the two vertical slits. Cantilevered bullet pieces.
[0007]
Further, in the contact contact surface portion between the indoor / outdoor direction adjusting member and the outer case, a meshing claw receiving portion in which a meshing claw is formed on one side and the meshing claw is engaged with the other side in the circumferential direction. And the indoor / outdoor direction adjusting member may be biased and provided on the door body side.
[0008]
