Description

【０００１】
【発明の属する技術分野】
本発明は、被吊り下げ物をガイドレールに移動可能に吊り下げ支持する吊り下げ支持装置およびこの吊り下げ支持装置が扉体に取り付けられた扉装置に関する。
【０００２】
【従来の技術】
従来、この種の扉装置としては、例えば特開平９−２７９９３４号公報に記載の構成が知られている。
【０００３】
この特開平９−２７９９３４号公報に記載の扉装置は、扉体の上端一側面に位置してガイドレール上を走行可能に係合し扉体を吊り下げ支持する吊り下げ支持装置を設けている。
【０００４】
そして、吊り下げ支持装置は、扉体の端部に固着して取り付けられるケース体を有している。また、このケース体には、扉体のガイドレールに沿った移動方向に軸方向を沿って配設した一対の調整ボルトの一方の回動により扉体の移動方向に沿ってケース体内を移動するプレート調整体が配設されている。そして、このプレート調整体には、移動方向に斜めに交差する案内溝が設けられている。また、ケース体には、上端部にガイドレール上を走行可能なガイドローラを有し下端部にプレート調整体の案内溝に係合する連結片を突設した走行手段が設けられ、調整ボルトの回動により移動するプレート調整体により、走行手段は扉体の移動方向に対して直交方向に移動する。さらに、ケース体には、他方の調整ボルトの回動により扉体の移動方向に沿ってケース体内を移動する上下調整ブロックが配設されている。また、ケース体には、回動自在に上下調整ブロックが係合するとともに走行手段が連結されて走行手段をケース体に支持する上下調整体が配設され、他方の調整ボルトの回動により移動する上下調整ブロックにより、上下調整体が回動し、連結された走行手段がケース体に対して上下方向に移動する。
【０００５】
【発明が解決しようとする課題】
しかしながら、上記特開平９−２７９９３４号公報に記載の扉装置では、扉体に取り付けられるケース体に対して、ケース体を吊り下げ支持する走行手段を上下方向および前後方向に移動させるために多くの部材を用いるので、製造性の向上および小型化が図りにくい。
【０００６】
本発明は、このような点に鑑みてなされたもので、被吊り下げ物の上下方向および前後方向への調整が少ない部品点数で可能となり、製造性が向上し小型化する吊り下げ支持装置および扉装置を提供することを目的とする。
【０００７】
【課題を解決するための手段】
請求項１記載の吊り下げ支持装置は、被吊り下げ物をガイドレールに移動可能に吊り下げ支持する吊り下げ支持装置であって、前記被吊り下げ物に取り付けられるケース体と、対向する一対の側板部、これら側板部の一端を連結する端板部、これら一対の側板部の前記端板部側でこの端板部の一端側に位置して前記一対の側板部に設けられたシャフト孔、前記一対の側板部の前記端板部側でこの端板部の他端側に位置し前記一対の側板部の縁から前記シャフト孔に向けて切欠形成された係合溝部、および前記シャフト孔と前記係合溝部との間に位置して前記端板部に設けられ上下方向に長手状の係合凹部を有し、前記ケース体内に前記被吊り下げ物の移動方向に対して直交かつ水平方向に前後方向調整移動可能でかつこの前後方向調整移動方向に沿って軸方向を有するシャフトにて回動可能に軸支される位置調整体と、前記ケース体に回動可能に設けられ、回動軸心に対して偏芯した位置に前記位置調整体の係合凹部内を移動可能に係合する係合突部を有し、回動により前記位置調整体を前記被吊り下げ物の移動方向に対して直交かつ水平方向に前後方向調整移動させる前後調整手段と、前記ケース体に配設され、回転可能に設けられた調整子および前記係合溝部に係合し前記調整子の回転により前記被吊り下げ物の移動方向に移動して前記位置調整体を上下方向に回動させる移動子を備えた上下調整手段と、前記位置調整体に連結され前記ガイドレールに移動可能に係合して前記ケース体を吊り下げ支持する走行手段とを具備したものである。
【０００８】
そして、被吊り下げ物を移動方向に対して直交かつ水平方向である前後方向に移動させる場合には、前後調整手段を回動し、前後調整手段の偏芯して突設した係合突部が係合する位置調整体の上下方向に長手状の係合凹部内を移動して前後調整手段の回動が被吊り下げ物の移動方向に対して直交かつ水平方向である前後方向の前後方向調整移動に変換され、位置調整体がケース体内を前後方向に移動する。この位置調整体の前後方向調整移動により、位置調整体に連結しガイドレールに移動可能に係合してケース体を吊り下げ支持する走行手段もケース体に対して前後方向に移動し、被吊り下げ物が前後方向に移動する。また、被吊り下げ物を上下方向に移動させる場合には、上下調整手段のケース体に回転可能に設けた調整子を回転してこの調整子に係合する移動子を被吊り下げ物の移動方向に移動させ、移動子が係合する位置調整体を被吊り下げ物の移動方向に対して直交かつ水平方向に軸方向を有するシャフトを回転軸として回動させる。この位置調整体の回動により、位置調整体に連結する走行手段も連動して移動し、位置調整体の回動軌跡の上下方向に沿ったベクトル分により走行手段がケース体に対して上下方向に移動し、被吊り下げ物が上下方向に移動する。したがって、被吊り下げ物の移動方向に対して直交かつ水平方向に前後方向調整移動可能でかつこの前後方向調整移動方向に軸方向を有するシャフトにて回動可能に軸支した位置調整体に前後調整手段および上下調整手段を直接係合させ、これら前後調整手段の回動および上下調整手段の回転により位置調整体を移動および回動させるため、部品点数が減少し、容易に製造性が向上するとともに小型軽量化する。
【０００９】
請求項２記載の吊り下げ支持装置は、請求項１記載の吊り下げ支持装置において、位置調整体は、シャフトに対して略水平方向に位置して略並列に軸方向を有し走行手段を連結する連結軸を備えたものである。
【００１０】
そして、回動軸となるシャフトに対して略水平方向に位置して略並列に軸方向を有して設けた連結軸により位置調整体と走行手段とを連結するので、位置調整体の回動軌跡が連結軸の位置で略上下方向に沿った回動となり、位置調整体の回動距離が走行手段の上下方向の移動となる。したがって、上下調整の効率が向上する。
【００１１】
請求項３記載の吊り下げ支持装置は、請求項１または２記載の吊り下げ支持装置において、上下調整手段の調整子は、雄ねじ部を有し軸方向が被吊り下げ物の移動方向に沿って軸方向へ移動することなく回転可能に配設され、上下調整手段の移動子は、前記雄ねじ部に螺合する雌ねじ部を有し平面方向が前記被吊り下げ物の移動方向に対して直交方向に沿った舌片状の係止爪部を備え、位置調整体の係合溝部は、前記被吊り下げ物の移動方向に対して直交かつ水平方向に沿って凹溝状で前記係止爪部が前記被吊り下げ物の移動方向に対して直交かつ水平方向に移動可能に係合するものである。
【００１２】
そして、被吊り下げ物を上下方向に移動するために上下調整手段の調整子を回転させた際、被吊り下げ物の移動方向に沿って軸方向を有して軸方向に移動不可能に配設した調整子の雄ねじ部に係合する雌ねじ部を設けた移動子が被吊り下げ物の移動方向に沿って移動し、移動子の舌片状の係止爪部が係合する位置調整体を回動させて上下方向に移動させる。また、位置調整体が前後調整手段により前後方向に前後方向調整移動される場合には、移動子の係止爪部は平面方向が被吊り下げ物の移動方向に対して直交かつ水平方向に沿って凹溝状に設けられ、係止爪部が位置調整体に被吊り下げ物の移動方向に対して直交かつ水平方向に沿って係合溝部を相対的に移動するので、上下方向の位置が可変することなく前後移動する。したがって、簡単な構造で位置調整体の前後方向の移動および上下方向の移動が互いに関与することなく移動可能となる。
【００１３】
請求項４記載の吊り下げ支持装置は、請求項１ないし３いずれか一記載の吊り下げ支持装置において、ケース体は、前後調整手段を回動可能に嵌挿し内周面に周方向に沿って凹凸状の係止部を設けた嵌挿孔を有し、前記前後調整手段は、嵌挿孔に嵌挿可能に周面が円筒状に形成され前記係止部に係脱可能に係止される爪部を有したものである。
【００１４】
そして、被吊り下げ物を前後方向へ移動させるために前後調整手段を回動した際、周面が円筒状の前後調整手段を嵌挿するケース体の嵌挿孔の内周面に周方向に沿って凹凸状の係止部を、前後調整手段の爪部が凹凸を乗り越えるように係脱しクリック感が得られ、所定位置に被吊り下げ物が移動した後は、係止部に爪部が係止されて前後調整手段の回動が規制される。したがって、簡単な構造で前後調整手段の回動および回動規制による位置決めが容易となる。
【００１５】
請求項５記載の吊り下げ支持装置は、請求項１ないし４いずれか一記載の吊り下げ支持装置において、前後調整手段および上下調整手段は、ケース体の一面側に臨んで配設されたものである。
【００１６】
そして、前後調整手段および上下調整手段をケース体の一面側に臨んで配設したため、ケース体の一面を外方に臨ませてケース体を被吊り下げ物に取り付けることにより、被吊り下げ物の前後方向への移動および上下方向への移動が一面側からの操作により可能となる。
【００１７】
請求項６記載の扉装置は、ガイドレールと、このガイドレールに走行手段が移動可能に係合する請求項１ないし５いずれか一記載の吊り下げ支持装置と、この吊り下げ支持装置に取り付けられる扉体とを具備したものである。
【００１８】
そして、部品点数が少なく製造性の向上および軽量小型化が容易な請求項１ないし５いずれか一記載の吊り下げ支持装置に扉体を取り付け、この吊り下げ支持装置の走行手段をガイドレールに係合して扉体をガイドレールに沿って移動させる。また、ガイドレールに吊り下げられる扉体は、吊り下げ支持装置の前後調整手段および上下調整手段を操作して扉体のガイドレールに対する位置を調整し、例えば扉体の開閉位置の調整や移動の際の他部位との干渉の防止のための調整などをする。したがって、部品点数が少なく製造性の向上および軽量小型化が容易な請求項１ないし５いずれか一記載の吊り下げ支持装置が取り付けられる扉体の小型化が図れる。
【００１９】
【発明の実施の形態】
以下、本発明の一実施の形態の扉装置を図面を参照して説明する。
【００２０】
図３および図４において、１は扉装置で、この扉装置１は、図示しない建造物の天井や家具などの天板などに沿って取り付けられた長手状のガイドレール２を備えている。このガイドレール２は、天井あるいは天板などに沿って例えばねじやボルト、接着剤などの図示しない取付部材にて取り付けられる細長板状の水平状部2aと、この水平状部2aの長手方向の一側縁に略垂直に折曲された垂直状部2bと、この垂直状部2bの折曲させた側の端部縁が水平状部2aに向けて湾曲して屈曲形成された円弧状のローラ係合部2cとを有している。そして、ガイドレール２は、垂直状部2bが天井あるいは天板などに対して下方に向けて突出し、ローラ係合部2cが上方に向けて円弧状に湾曲して天井あるいは天板などに取り付けられる。なお、ガイドレール２は、ローラ係合部2cの水平状部2aに向けて屈曲する端部縁と水平状部2aとの間にはローラ挿入口2dが開口されている。
【００２１】
一方、４は例えば被吊り下げ物としての引戸である扉体で、この扉体４は、図示しない建造物の間口や家具の開口を開閉可能な平板状に形成され、上端面4aおよび一側面4bの２面に亘って開口する矩形状の埋設凹部4cを例えば２箇所設けている。そして、埋設凹部4cには吊り下げ支持装置５が固着され、扉体４は吊り下げ支持装置５の上端面4aから一部が突出してガイドレール２のローラ係合部2cに係合し扉体４をガイドレール２に沿って移動可能に吊り下げ支持される。
【００２２】
そして、吊り下げ支持装置５は、扉体４の埋設凹部4c内に例えば圧入されて埋設されるケース体６を備えている。このケース体６は、合成樹脂などにて一対の側板6a，6aと一対の端板6b，6bと底部6cとにて上面に開口部6dを開口する内室７を有し扉体４の埋設凹部4cに対応する形状の略偏平箱状に形成されている。そして、ケース体６の底部6cには、埋設凹部4cへのケース体６の装着の際にケース体６を案内して装着が容易となるように下面が埋設凹部4cの底面に対応して円弧状に形成され補強用に肉厚に形成された肉厚部6eが設けられている。
【００２３】
また、ケース体６の肉厚部6eには、扉体４の移動方向となる扉体４の幅方向であるケース体６の長手方向に沿って通孔状、すなわち扉体４の埋設凹部4c内に取り付けられた際に扉体４の一側面に臨む一方の端板6bから反対側の他方の端板6bに取付手段としての木ねじなどのねじ８を貫通する通孔状のねじ孔９が設けられている。このねじ孔９は、ねじ８の頭部8aを嵌挿し扉体４の一側面に臨む一方の端板6bに開口する径大孔部9aとねじ８の雄ねじ8bが嵌挿され頭部8aが嵌挿不可能で反対の他方の端板6bに開口する径小孔部9bとが同軸状に形成され、径大孔部9aと径小孔部9bとの間にはねじ８の頭部8aが当接する段差状にねじ頭当接部9cが設けられている。そして、ねじ孔９に貫通するねじ８の雄ねじ8bがケース体６の反対側の端板6bから突出して扉体４に螺着し、ケース体６を扉体４に取り付けるようになっている。
【００２４】
さらに、ケース体６の一方の端板6bには、内室７に対応する位置に、凹状に操作凹部11が設けられている。また、ケース体６には、ねじ孔９と略平行に一方の端板6bの操作凹部11から他方の端板6bに内室７に連通して通孔状の軸支孔部12が設けられている。この軸支孔部12は、操作凹部11側の縁および他方の端板6bの縁がそれぞれ同軸状に径大に形成された軸支凹部12aがそれぞれ設けられている。
【００２５】
そして、この軸支孔部12には、中間部の外周面に雄ねじ部14を有した略円柱状の軸部15と、この軸部15の一端に設けられ例えばプラスドライバなどの治具が係合可能な操作溝部16を有する径大の操作頭部17とを有した調整子18が回転自在に嵌挿されている。この調整子18は、操作頭部17が操作凹部11側の一方の軸支凹部12a内に係合し、雄ねじ部14がケース体６に接触することなく軸部15が回転自在に軸支孔部12に嵌挿されている。また、軸部15の操作頭部17が設けられた側と反対側の他端部には、例えばリング状に形成され軸支孔部12を挿通不可能に軸支凹部12a内に係合する抜止部材19が設けられている。そして、調整子18は、操作頭部17および抜止部材19にて、軸方向が扉体４の移動方向となるケース体６の長手方向である端板6b，6bの対向方向に沿って軸方向に移動不可能に回転自在に軸支されている。
【００２６】
さらに、調整子18には、移動子21が取り付けられている。この移動子21は、扉体４の移動方向に対して直交方向である扉体４の厚さ方向となるケース体６の幅狭方向、すなわちケース体６の側板6a，6aの対向方向に沿った平面を有する平板状に形成されている。また、移動子21の略中央には、調整子18の軸部15の雄ねじ部14が螺合する雌ねじ部22が設けられている。一方、ケース体６の底部6cには、内室７内の上方に向けて凹状で操作凹部11が設けられた端板6b側に位置して案内凹部23が設けられている。そして、移動子21は、この案内凹部23内に下端部が移動可能に係合し、上端部が扉体４の移動方向に対して直交方向に平面を有する舌片状の係止爪部24を構成し、調整子18の回転により移動子21が扉体４の移動方向に沿って案内凹部23内の範囲で移動する。
【００２７】
なお、調整子18の雄ねじ部14および移動子21の雌ねじ部22は、調整子18の回転により移動子21が移動するが移動子21に移動される力が加わっても調整子18は回転しないように、進み角が小さく形成されてセルフロック機構を有する。そして、調整子18と移動子21とにて上下調整手段25が構成されている。
【００２８】
また、ケース体６の操作凹部11内には、内室７に連通する嵌挿孔31が設けられている。この嵌挿孔31は、操作凹部11側の縁が径大に形成されて嵌挿凹部32が設けられ、内室７側の内周面が嵌挿凹部32側に向けてラッパ状に拡開するテーパ面33が設けられ、嵌挿孔31の内室７側の縁が抜止爪部34となっている。さらに、嵌挿凹部32の内周面には、周方向に沿って凹凸状、すなわち内周面に係止部としての内歯車35が設けられている。
【００２９】
そして、この嵌挿孔31には、前後調整手段37が設けられている。この前後調整手段37は、嵌挿凹部32内に嵌挿され一面略中央に例えばプラスドライバなどの治具が係合可能な操作窪み部38を有した略円板状の操作板部39と、この操作板部39の他面側略中央に略同軸状に設けられ嵌挿孔31に回転自在に嵌挿される略円柱状の軸支部40と、軸支部40の端部周縁に径大に鍔状に形成されケース体６の抜止爪部34に係止されるフランジ部41と、軸支部40の端面に軸心が偏位して突設された係合突部42とを備えている。また、操作板部39の外周面の一部には、内歯車35に係脱、すなわち内歯車35の歯を乗り越え可能に係合する爪部43が設けられている。そして、前後調整手段37は、係合突部42が内室７内に突出して圧入され、フランジ部41がケース体６の抜止爪部34に係止されて嵌挿孔31に回転可能に嵌挿され、爪部43が内歯車35の歯を乗り越えることによりクリック感が付与されて回転し、爪部43が内歯車35の歯に係止されて回転規制される。
【００３０】
なお、操作板部39の一面には、矢印状の表示部44が設けられている。この表示部44は、係合突部42の突設する位置に対応して設けられ、係合突部42が最下位置、すなわち操作板部39を回転操作することにより移動する円周軌跡の軸支部40の中心の下方に中心が位置する最下位置となる際に下方に矢印が向くように設けられている。
【００３１】
一方、ケース体６には、上面の開口部6dの近傍でかつ操作凹部11側に位置して、扉体４の厚さ方向である幅方向、すなわち側板6a，6aの対向方向に沿って軸方向を有するシャフト45を軸支する軸受孔46を内室７を介して側板6a，6aに貫通形成されている。また、ケース体６には、上面の開口部6dの近傍で軸受孔46と反対側には、開口部6dの縁に連続して上下方向に沿って溝状の軸受溝部47が側板6a，6aの対向面に対向して設けられている。
【００３２】
そして、ケース体６の内室７内には、シャフト45に回転自在かつシャフト45の軸方向に摺動自在に位置調整体50が軸支されて配設されている。この位置調整体50は、例えば鋼板などにて折曲形成され、対向する一対の側板部50a，50aと、これら側板部50a，50aの一縁にそれぞれを連結する端板部50bとにて断面略コ字状に形成されている。そして、一対の側板部50a，50aには、端板部50b側で端板部50bの一端側に位置してシャフト45を回転自在に貫通するシャフト孔51が設けられ、位置調整体50は端板部50bがケース体６の端板6bに対向してケース体６に軸支されたシャフト45を回転軸としてケース体６内で回動自在かつシャフト45の軸方向である前後調整方向にシャフト45に案内されるように移動自在に軸支されている。
【００３３】
また、側板部50a，50aには、ケース体６の軸受溝部47に対応する位置に、棒状の連結軸52が回転自在に貫通する連結軸孔53が設けられている。そして、位置調整体50の回動に伴って、連結軸52は、ケース体６の側板6a，6aの内面が接触しないように逃げとなる軸受溝部47，47に沿って上下方向に移動する。
【００３４】
さらに、位置調整体50には、側板部50a，50aの端板部50b側で端板部50bの他端側であるシャフト孔51と反対側に位置して、下方であるシャフト孔51と反対側の側板部50aの縁からシャフト孔51に向けて係合溝部としての切欠部54がそれぞれ対向して切欠形成されている。これら切欠部54，54は、端板部50bと反対側の一縁がさらに凹状に切り欠かれて逃げ部55がそれぞれ設けられている。そして、これら切欠部54，54には上下調整手段25の移動子21がケース体６の幅方向に沿って相対的に移動可能に係合し、この移動子21が係合した状態で位置調整体50がシャフト45の軸方向に沿って移動可能であるとともに、移動子21の移動によりシャフト45を中心軸として位置調整体50が回動する。なお、位置調整体50は、シャフト45にて軸支された位置と連結軸52の軸支位置とが略水平方向に略並列となるようにケース体６内に配設されている。すなわち、位置調整体50は、移動子21の水平方向である扉体４の移動方向に沿った移動により連結軸52が最も大きく上下方向へ移動する状態に配設することが好ましい。
【００３５】
また、位置調整体50の端板部50bには、上下方向である端板部50bの長手方向に沿って長手状の係合凹部としての係合孔部56が設けられている。そして、この係合孔部56には前後調整手段37の係合突部42が嵌挿係合され、前後調整手段37の操作板部39の回動操作により偏芯して設けられ上下方向に長手状の係合孔部56に係合する係合突部42が円周軌道上を移動するように回行することで、この回行がケース体６の幅方向である前後方向に沿った移動に変換されて位置調整体50がシャフト45の軸方向に沿って移動する。
【００３６】
一方、吊り下げ支持装置５には、ガイドレール２にケース体６を移動可能に吊り下げ支持、すなわちケース体６が固着される扉体４を移動可能に吊り下げ支持する走行手段60が設けられている。この走行手段60は、平板部61aと、この平板部61aの一縁に断面略Ｌ字状となるように折曲形成された支持板部61bと、この支持板部61bの略中央一縁に平板部61aと略平行に折曲形成された連結板部61cとにて構成されたシャーシ部61を備えている。
【００３７】
そして、シャーシ部61の平板部61aには、支持板部61bの折曲側に突出して一対の車輪軸62，62が設けられている。これら車輪軸62，62は、一端が片持ち状態で支持され、支持板部61bの平面方向である水平方向に並列に支持されている。また、車輪軸62，62の他端側には、ガイドレール２のローラ係合部2c上を走行可能に係合する走行輪63が回転自在にそれぞれ軸支されている。なお、走行輪63の径寸法は、図３に示すように、ガイドレール２のローラ挿入口2dより径大で、かつ、ローラ係合部2cの内周面と水平状部2aとの最大対向距離より径小に形成されている。そして、走行輪63，63は、略中央が連結板部61cの平面上に位置するように回転自在に軸支されている。
【００３８】
また、シャーシ部61の連結板部61cには、連結通孔65が穿設されている。そして、連結板部61cの両面に座金66，66をそれぞれ位置させて連結板部61cが位置調整体50の側板部50a，50a間に嵌挿され、連結軸52が位置調整体50の連結軸孔53，53を介して連結通孔65に回転自在に嵌挿され、位置調整体50と走行手段60のシャーシ部61とが連結軸52にて互いに回転自在に連結され、ケース体６の内室７内に配設された位置調整体50により走行手段60がケース体６に取り付けられる。
【００３９】
次に、上記実施の形態の組立動作を説明する。
【００４０】
まず、ケース体６内の案内凹部23に移動子21の一縁を挿入するとともに、調整子18の軸部15をケース体６の軸支孔部12に操作凹部11側から嵌挿し、移動子21の雌ねじ部22に軸部15の雄ねじ部14を螺合して軸支孔部12の反対側の軸支凹部12aに嵌挿し、軸支凹部12aに突出する軸部15の先端に抜止部材19を取り付けて回転自在に軸支し、ケース体６に上下調整手段25を配設する。
【００４１】
一方、あらかじめシャーシ部61の平板部61aに車輪軸62を支持して走行輪63を回転自在に軸支して組立形成した走行手段を位置調整体50に連結する。すなわち、走行手段60のシャーシ部61の連結板部61cの両面に座金66，66をそれぞれ位置させて連結板部61cを位置調整体50の側板部50a，50a間に嵌挿し、連結軸52を位置調整体50の連結軸孔53，53を介して連結通孔65に回転自在に嵌挿して連結する。
【００４２】
そして、走行手段60を連結した位置調整体50を、連結軸52の両端部をケース体６の軸受溝部47，47に対向するように位置し、位置調整体50の端板部50bをケース体６の端板6bに対向させて内室７内に挿入する。この後、あらかじめケース体６に配設した上下調整手段25の移動子21の上端部分である係止爪部24を位置調整体50の切欠部54に係合させて挿入し、ケース体６の軸受孔46と位置調整体50のシャフト孔51とを位置合わせして、軸受孔46とシャフト孔51とにシャフト45を嵌挿して固定し、位置調整体50をケース体６内に配設する。
【００４３】
さらに、ケース体６の嵌挿孔31に前後調整手段37の係合突部42から嵌挿し、フランジ部41が抜止爪部34を乗り越えるように圧入して前後調整手段37をケース体６に取り付けて、吊り下げ支持装置５を組立形成する。なお、この前後調整手段37の取付の際、前後調整手段37の表示部44が下方に矢印が向く状態で圧入し、位置調整体50を適宜前後方向に移動しつつ前後調整手段37の係合突部42を位置調整体50の係合孔部56に係合させる。
【００４４】
そして、吊り下げ支持装置５のケース体６を、あらかじめ形成した扉体４の埋設凹部4c内に、操作凹部11が扉体４の一側面4bに臨みかつケース体６の上端面が扉体４の上端面に突出することなく略面一となるように圧入する。この後、ねじ８をねじ孔９に嵌挿し、扉体４にねじ８をねじ込んで吊り下げ支持装置５を扉体４に取り付ける。なお、この吊り下げ支持装置５は、例えば扉体４の上端部の両側に位置して一対、すなわち２個取り付けられる。
【００４５】
また、ガイドレール２に吊り下げ支持装置５により扉体４を移動可能に吊り下げ支持する場合には、走行手段60の走行輪63，63の下端縁、すなわち走行輪63，63の扉体４側の縁をガイドレール２のローラ係合部2cの端部縁に係合させるように扉体４を傾けてローラ挿入口2dからローラ係合部2cの湾曲する内周面側に挿入する。そして、ローラ係合部2cの内周面に係合する走行輪63，63の縁を中心に傾けた扉体４を平面方向が鉛直方向となるように回動させて走行輪63，63の反対側である上端部をローラ挿入口2d内に挿入して、ガイドレール２に扉体４を吊り下げ支持する。そして、扉体４は、ガイドレール２のローラ係合部2d上に係合する走行輪63，63の走行により、ガイドレール２に沿って移動する。
【００４６】
次に、前記実施の形態の調整動作を説明する。
【００４７】
扉体４の下端縁が図示しない建造物の床面や地面などに接触して扉体４の移動の障害や扉体４の下端部を損傷するなどのおそれがある場合、あるいは建造物の間口や家具の開口の下端縁を閉塞できずに隙間が開いてしまう場合などには、ガイドレール２に対して扉体４を上方あるいは下方に移動させて調整する。
【００４８】
すなわち、上下調整手段25の調整子18を所定方向、例えば扉体４を上方に移動させたい場合には調整子18を時計回りに回転させ、扉体４を下方に移動させたい場合には調整子18を反時計回りに回転させる。この調整子18の回転により、例えば調整子18を時計回りに回転させることにより移動子21がケース体６の端板6bに近付く方向に移動し、反時計回りに回転させることにより移動子21が端板6bから遠ざかる方向に移動する。
【００４９】
そして、この移動子21の移動により、この移動子21の上端部分である係止爪部24が切欠部54に係合する位置調整体50が移動子21の移動方向に沿ってシャフト45を中心軸として回動する。すなわち、例えば移動子21がケース体６の端板6bに近付く方向に移動させた場合には、位置調整体50の端板部50bが端板6bに近付くように回動し、移動子21が端板6bから遠ざかる方向に移動させた場合には、位置調整体50の端板部50bが端板6bから遠ざかる方向に回動する。そして、この位置調整体50の上下方向の回動により、位置調整体50に走行手段60を連結させる連結軸52が軸受溝部47に案内されて上下方向に移動、すなわち位置調整体50の端板部50bが端板6bに近付くように回動することにより連結軸52が下方であるケース体６の底部6cに向けて移動し、位置調整体50の端板部50bが端板6bから遠ざかる方向に回動することにより連結軸52が上方であるケース体６の開口部6dに向けて移動する。
【００５０】
さらに、位置調整体50の回動による連結軸52の上下方向への移動により、走行手段60が上下方向に移動、すなわち連結軸52の下方への移動により走行手段60がケース体６に対して没入する方向である下方に移動し、連結軸52の上方への移動により走行手段60がケース体６に対して進出する方向である上方に移動する。この走行手段60の上下方向への移動により、ガイドレール２に係合する走行手段60に吊り下げられた状態のケース体６が一体的に取り付けられた扉体４が上下方向に移動、すなわち走行手段60の下方への移動により扉体４が相対的に上方に持ち上げられるように移動し、走行手段60の上方への移動により扉体４が相対的に下方に移動される。
【００５１】
このようにして、上下調整手段25の調整子18の操作により、扉体４の上下方向の位置を調整する。
【００５２】
一方、扉体４が移動の際に図示しない建造物や家具などの壁や間仕切りなどに接触して建造物や家具、扉体４を損傷するおそれがある場合、あるいは建造物の間口や家具の開口との間隔が広すぎて閉塞できなくなる場合などには、ガイドレール２に対して扉体４を前後、すなわち扉体４の移動方向に対して略直交する方向である扉体４の平面に対して略垂直方向の厚さ方向に移動させて調整する。
【００５３】
すなわち、前後調整手段37の操作板部39を所定方向、例えば扉体４を後方である扉体４を建造物の間口や家具の開口に近付く方向に移動させたい場合には操作板部39を時計回りに回転させ、扉体４を前方である建造物の間口や家具の開口との間隔を広げる方向に移動させたい場合には操作板部39を反時計回りに回転させる。この操作板部39の回転により、例えば操作板部39を時計回りに回転させることにより前後調整手段37の係合突部42が扉体４の厚さ方向に沿って最下位置から前方に向けて円周軌道上を移動するように回行し、反時計回りに回転させることにより前後調整手段37の係合突部42が扉体４の厚さ方向に沿って最下位置から後方に向けて円周軌道上を移動するように回行する。
【００５４】
そして、この係合突部42の回行により、この係合突部42が係合する上下方向に長手状の係合孔部56を有した位置調整体50は、係合突部42の回行が扉体４の厚さ方向への移動に変換されて前後方向に移動する。すなわち、位置調整体50は、係合突部42が前方に回行することによりケース体６内を前方に移動し、係合突部42が後方に回行することによりケース体６内を後方に移動する。
【００５５】
なお、位置調整体50に係合する上下調整手段25の移動子21は、位置調整体50の側板部50a，50aに対向して同形状に形成し位置調整体50の前後方向への移動方向に溝状の切欠部54，54に係合する。このため、位置調整体50の前後方向への移動の際に、移動子21は位置調整体50の切欠部54，54内を相対的に移動する状態となるので、移動子21が係合した状態でも位置調整体50は前後方向へ移動可能となる。
【００５６】
そして、位置調整体50の前後方向への移動に伴って、連結された走行手段60も前後方向に移動する。すなわち、位置調整体50の前方への移動により走行手段60がケース体６に対して前方である扉体４の厚さ方向の前方に相対的に移動する状態となり、位置調整体50の後方への移動により走行手段60がケース体６に対して後方である扉体４の厚さ方向の後方に相対的に移動する。この走行手段60の相対的な前後方向への移動により、ガイドレール２に係合する走行手段60に吊り下げられた状態のケース体６が一体的に取り付けられた扉体４が前後方向に移動する。すなわち、走行手段60の前方への移動により扉体４が相対的に建造物の間口や家具の回行に近付く方向である後方に移動し、走行手段60の後方への移動により扉体４が相対的に間口や回行から遠ざかる方向の前方に移動される。
【００５７】
このようにして、前後調整手段37の操作により、扉体４の前後方向への位置を調整する。
【００５８】
上述したように、上記実施の形態では、扉体４の移動方向に沿って回動可能でかつ扉体４の移動方向に対して直交かつ水平方向に移動可能に軸支した位置調整体50に前後調整手段37および上下調整手段25を直接係合させ、これら前後調整手段37の回動および上下調整手段25の回転操作により位置調整体50を前後方向あるいは上下方向に移動させて扉体４の位置を調整するため、部品点数を減少でき、容易に製造性を向上できるとともに小型軽量化できる。したがって、吊り下げ支持する扉体４を吊り下げ支持装置５に合わせて小型化できる。
【００５９】
さらに、ケース体６の嵌挿孔31の内周面に内歯車35を設け、この嵌挿孔31に嵌挿する前後調整手段37の外周面に内歯車35に係脱可能な爪部43を設けたため、簡単な構成で前後調整手段37の回転操作の際にクリック感が得られ、操作性を向上できるとともに、回転操作しないときには内歯車35に爪部43が係合して回転規制して回り止めするので、位置決めが簡単な構成で容易にできる。
【００６０】
そして、嵌挿孔31に抜止爪部34を設け、前後調整手段37に抜止爪部34に係止されるフランジ部41を設けたため、前後調整手段37をケース体６の端板6bの外面から押し込むように取り付けることができ、一部品で容易に一動作で取り付けできる。
【００６１】
また、上下調整手段25の調整子18を雄ねじ部14を有し軸方向が扉体４の移動方向に沿って軸方向へ移動することなく回転可能に配設し、上下調整手段25の移動子21に雄ねじ部14に螺合する雌ねじ部22を設け、位置調整体50に扉体４の移動方向に対して直交方向に沿って移動子21の平面方向が扉体４の移動方向に対して直交方向に沿った舌片状の係止爪部24が扉体４の移動方向に対して直交方向に移動可能に係合する切欠部54，54を設けたため、簡単な構造で位置調整体50の前後方向の移動および上下方向の移動が互いに関与することなくできる。
【００６２】
そして、前後調整手段37および上下調整手段25をケース体６の一面側である一方の端板6bに臨んで配設したため、ケース体６の一面を外方に臨ませてケース体６を扉体４に取り付けることにより、扉体４の前後方向への移動および上下方向への移動が一面側からの操作のみによりでき、操作性を向上できるとともに、扉体４の目立たない一側面4bに前後調整手段37および上下調整手段25が臨むため、美観が低下することを防止できる。
【００６３】
さらに、前後調整手段37および上下調整手段25を扉体の一側面4bに臨むように偏平型のケース体６の端面に臨ませて配設したため、シャフト45による位置調整体50の回動中心から連結された走行手段60との連結位置までの距離を長く設定でき、上下調整手段25の調整子18の回転操作により、効率よく上下方向への移動ができる。
【００６４】
また、位置調整体50に連結軸52にて走行手段60を互いに回動可能に連結したため、位置調整体50の回動による走行手段60の相対的な上下方向への移動による扉体４の上下方向への位置調整が簡単な構造で容易にできる。
【００６５】
なお、上記実施の形態において、扉体４をガイドレール２に移動可能に吊り下げ支持する構成について説明したが、扉体４に限らず、例えばリフトコンベヤなどのように、いずれの物品をガイドレール２に移動可能に吊り下げ支持してもよい。
【００６６】
また、木ねじなどのねじ８にて吊り下げ支持装置５を扉体４に取り付け固定して説明したが、あらかじめ扉体４の埋設凹部4cに臨んで埋設したナットにねじ８を螺合して取り付けたり、ケース体６に埋設凹部4cへの取り付け方向に順目で埋設凹部4cから取り外す方向に逆目となる爪状の突起などを設けて圧入のみで取り付けたり、接着剤などにて取り付けるなどいずれの取り付け方法でもよく、さらに別途取付固定する構成を設けてもよい。
【００６７】
さらに、走行手段60を構成する走行輪63，63をガイドレール２に係合させて走行輪63，63の走行により移動させる構成について説明したが、例えばカーテンレールなどのように表面の摩擦抵抗が小さく設定された部材をガイドレール２に係合させて移動可能に係合させるなど、いずれの構成でもできる。
【００６８】
一方、前後調整手段37の係合突部42が係合する位置調整体50の係合凹部として、上下方向に長孔状の係合孔部56を設けたが、単に上下方向に凹溝状に設けるなど、長孔状に限られるものではなく、係合突部42が移動可能に係合するいずれの構成でもよい。
【００６９】
そして、調整子18の雄ねじ部14および移動子21の雌ねじ部22を進み角が小さくなるように設定してセルフロック機構を付与したため、別途調整子の回転を規制するストッパなどの構成が不要となり、構造を簡略化できる。なお、例えば嵌挿孔31の内歯車35に係合する前後調整手段37の爪部43のように、別途ストッパなどの回転を規制する構成を設けてもよい。
【００７０】

請求項２記載の吊り下げ支持装置によれば、請求項１記載の吊り下げ支持装置の効果に加え、シャフトに対して略水平方向に位置して略並列に設けた連結軸により位置調整体と走行手段とを連結したため、位置調整体の回動軌跡が連結軸の位置で略上下方向に沿った回動となり、位置調整体の回動距離が走行手段の上下方向の移動となるので、効率よく上下調整できる。
【００７２】
請求項３記載の吊り下げ支持装置によれば、請求項１または２記載の吊り下げ支持装置の効果に加え、上下調整手段の調整子に雄ねじ部を設けて軸方向を被吊り下げ物の移動方向に沿って軸方向へ移動することなく回転可能に配設し、上下調整手段の移動子に雄ねじ部に螺合する雌ねじ部および平面方向が被吊り下げ物の移動方向に対して直交方向に沿った舌片状の係止爪部を設け、被吊り下げ物の移動方向に対して直交かつ水平方向に沿って係止爪部が被吊り下げ物の移動方向に対して直交かつ水平方向に移動可能に係合する凹溝状の係合溝部を位置調整体に設けたため、係止爪部が位置調整体に被吊り下げ物の移動方向に対して直交かつ水平方向に沿って凹溝状の係合溝部を相対的に移動するので、位置調整体の上下方向への位置を可変することなく前後移動し、簡単な構造で位置調整体の前後方向の移動および上下方向の移動が互いに関与することなく移動できる。
