Description

【０００１】
【発明の属する技術分野】
本発明は、絵画や各種の展示物等を壁や天井等に吊り下げるための吊下げ装置に関するものである。
【０００２】
【従来の技術】
従来、壁又は天井に取り付けられたレールに吊り具を着脱自在に取り付けるようにした吊下げ装置がある（特許文献１参照）。
この吊下げ装置にあっては、レールは、四角筒状の筒体の一壁部に、レールの長手方向に開口部を形成して構成され、開口部側が吊り具取付面とされ、この吊り具取付面側には、開口部を挟むように一対の支持壁を有し、該吊り具取付面と対向する壁部がレールを壁又は天井に取付固定するための取付壁とされている。
【０００３】
一方、吊り具は、レールの開口部から内部のレール溝内に挿入可能とされると共に吊り具取付面に直交する方向の回転軸心回りに９０°回転させることにより支持壁の背面側に接当可能な抜け止めブロックと、紐等の引掛け部材を引っ掛けるためのフック部材と、これら抜け止めブロックとフック部材との間に設けられていて抜け止めブロックの回転軸心と同心状の軸心を有するボルト部材と、このボルト部材の外面に螺合されるナット部材と、このナット部材の端面に設けられる平座金と、ナット部材の内側に収容されるコイルバネとを備えている。
【０００４】
この吊下げ装置にあっては、抜け止めブロックを開口部からレール溝内に挿入した後、該抜け止めブロックを９０°回転させて該抜け止めブロックがレールの支持壁の背面側に接当するように位置させ、その後、ナット部材を締め付けることにより、レールの支持壁が抜け止めブロックと平座金とで挟持されることにより、レールに吊り具が取付固定されるようになっている。
前記フック部材は、ボルト部材の軸心に沿う方向に突出する天井取付姿勢と、この天井取付姿勢から背面側に９０°回転した壁取付姿勢とに姿勢変更自在となるように、ボルト部材に固定の取付部に枢着されている。
【０００５】
この吊下げ装置にあっては、ナット部材を締め付けることにより、吊り具をレールに取付固定するようにしているので、ナット部材を回転させる操作が煩雑で面倒であるという問題がある。
そこで、吊り具をレールにワンタッチで取り付けられるようにした吊下げ装置がある（特許文献２参照）。
この吊下げ装置の吊り具は、レールの吊り具取付面に接当するベース部材と、このベース部材に対して吊り具取付面に直交する方向の回転軸心回りに回転自在な支持部材と、この支持部材に取付固定されたフック部材と、レール溝内に位置していて前記ベース部材とで支持壁を挟み込むことによりレールに対して吊り具を取付固定する係止部材とを備えており、係止部材は、支持部材と一体回転自在とされていて、該支持部材を回転させることにより係止部材が開口部からレール溝に挿脱自在な姿勢に姿勢変更自在とされている。
【０００６】
この吊下げ装置にあっては、係止部材をレールの開口部からレール溝内に挿入すると共にベース部材を支持壁の外面（吊り具取付面）に接当させた後、該係止部材を支持部材と共に回転軸心回りに９０°回転させて係止部材を支持壁の背面側に接当させることにより、レールの支持壁が係止部材とベース部材とで挟持され、これにより吊り具がワンタッチでレールに取付固定されるように構成されている。
なお、この吊下げ装置の吊り具は、支持部材から回転軸心方向に直交する方向に突出状として該支持部材に固定されており、壁に固定されたレールに取り付けられる壁付け専用のものとされている。

【発明が解決しようとする課題】
前記特許文献２の吊り具の取付構造の吊下げ装置において、天井に取付固定されたレールに吊り具を取り付けるようにする場合、フック部材は、支持部材から回転軸心方向に沿う方向に突出状として支持部材に固定される。
この場合において、レールは開口部が下向きとなるように天井に取り付けられ、吊り具は、下方側から係止部材を開口部を介してレール溝内に挿入し、フック部材の先端側を指でつまんで回転軸心回りに９０°回転させることにより、レールに取り付けられる。
【０００９】
しかしながら、レールを天井に取り付ける場合、通常、レールは壁際に取り付けられるので、吊り具をレールに取り付ける際において、フック部材を指でつまんで回転操作しにくいという問題がある。
また、係止部材を回転させてレールの支持壁を該係止部材とベース部材とで挟持する際のフック部材の回転操作は比較的固いことから、フック部材を指でつまんで回転操作するのは困難である。
そこで、本発明は、前記問題点に鑑みて、天井に取り付けられたレールに吊り具を容易に取り付けられるように考慮した吊下げ装置を提供することを目的とする。
【００１０】
【課題を解決するための手段】
本発明が技術的課題を解決するために講じた技術的手段は、レールと、このレールに取り付けられる吊り具とを備え、レールの吊り具取付面側には、レールの長手方向に形成されたレール溝の開口部と、この開口部を挟むように位置する一対の支持壁とを備え、吊り具は、レールの吊り具取付面に接当するベース部材と、このベース部材に対して吊り具取付面に略直交する方向の回転軸心回りに回転自在な支持部材と、この支持部材に一体回転自在に取り付けられ且つ正面側から引掛け可能とされたフック部材と、レール溝内に位置していて前記ベース部材とで支持壁を挟み込むことによりレールに対して吊り具を取付固定する係止部材とを備え、前記係止部材は支持部材と一体回転自在とされていて該支持部材を回転させることにより該係止部材が開口部を通過可能な姿勢に姿勢変更自在とされ、フック部材は、支持部材から回転軸心方向に沿う方向に突出状とされた状態からフック部材の正面側に倒れ得るように支持部材に枢着されており、このフック部材を正面側に倒した状態で且つフック部材がレールの長手方向に沿う状態で、開口部が下を向くように設けられたレールの該開口部から係止部材がレール溝内に挿入され、この状態でフック部材を回転軸心回りに回転させることにより、吊り具がレールに取り付けられるように構成されていることを特徴とする。
【００１１】
また、フック部材が、支持部材から回転軸心に沿う方向に突出状とされた天井取付姿勢と、この天井取付姿勢からフック部材が背面側に回転して支持部材から回転軸心に略直交する方向に突出状とされた壁取付姿勢とに姿勢変更とされていてもよい。
また、フック部材の支持部材への取付け部分を覆うキャップ部材を備え、このキャップ部材には、フック部材の、天井取付姿勢から壁取付姿勢への姿勢変更を許容するための切欠き溝が形成され、この切欠き溝によって、フック部材の、天井取付姿勢から正面側への回転を許容するように、キャップ部材が支持部材に回転軸心回りに回転自在に取り付けられているのがよい。
【００１２】
また、開口部を備えたレールと、このレールに取り付けられる吊り具とからなり、前記吊り具は、レールの吊り具取付面に接当するベース部材と、前記レール内部に位置していて前記ベース部材とでレールを挟み込むことにより吊り具を取り付ける係止部材と、前記吊り具取付面に略直交する方向の回転軸心回りに前記係止部材と一体に回転し且つ前記回転軸心に沿う方向に突出状とされた姿勢から引掛け可能な正面側及び背面側に倒れ得るように枢着されたフック部材とを備え、前記開口部から係止部材をレール内部に挿入し且つ前記フック部材を正面側又は背面側のいずれか一方に倒した状態で、前記フック部材を回転軸心回りに回転させることで、係止部材が吊り具をレールに取り付ける姿勢と開口部を通過可能な姿勢とに変更できるように構成され、前記フック部材の取付け部分を覆うキャップ部材が前記ベース部材に対して回転軸心回りに回転自在に設けられ、前記キャップ部材には、前記正面側又は背面側のいずれか一方のみにフック部材が倒れることを許容し且つ前記フック部材が回転軸心に沿う方向に突出した姿勢であるときのみにキャップ部材の回転軸心回りの回転を許容する切欠き溝が形成されていてもよい。
【００１３】
また、前記ベース部材には、前記レールの吊り具取付面に接当する接当面と、前記レールの開口部に挿入可能となるように前記接当面よりも一段突出して設けられ且つ前記開口部に嵌まることにより、前記係止部材の回転軸心回りの回転に対し、ベース部材の回り止めをする突出部とが形成されているのがよい。
【００１４】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照して説明する。
図１〜図３において、１は絵画や各種の展示物等を吊り下げるための吊下げ装置であり、この吊下げ装置１は、レール２と、このレール２に着脱自在に取り付けられる吊り具３とを備えている。
このレール２は、レール２の長手方向に直交する方向で対向状とされた一対の対向壁４と、この一対の対向壁４の幅方向一端縁側同志を連結するように設けられた取付壁５と、各対向壁４の幅方向他端縁側から対向方向に延設された一対の支持壁６とを備えてなり、このレール２は支持壁６間がレール溝７の開口部８とされていると共に、取付壁５が壁９又は天井１０に取付固定される（即ち、このレール２は、四角筒状の筒体の一側面にレール２の長手方向の開口部８を形成することにより構成され、前記開口部８を挟むように一対の支持壁６を備えている）。
【００１５】
なお、レール２は、少なくともレール溝７と開口部８と一対の支持壁６とを備えていればよく、全体的な断面形状は四角筒状でなくてもよく、どのような形状に形成されていてもよく、例えば、レール２は、天井１０と壁９との接する部分に設けられる回り縁に、前記レール溝７と開口部８と一対の支持壁６とを備えたものであってもよい。また、壁９に取り付けられるレール２と天井１０に取り付けられるレール２とは断面形状が異なるものであってもよい。
レール２の取付壁５は壁９又は天井１０に、取付壁５をレール溝７内から貫通して壁９又は天井１０にねじ込まれるネジ等によって取り付けられ、図３（ａ）に示すように、レール２が壁９に取り付けられる場合は開口部８が横方向（水平方向）を向き、図３（ｂ）に示すように、レール２が天井１０に取り付けられる場合は、開口部８が下方を向くように取り付けられる。
【００１６】
また、レール２外面の開口部８形成側が吊り具取付面１２とされ、図３（ａ）、（ｂ）に示すように、このレール２の吊り具取付面１２側に吊り具３がレール２の長手方向任意の位置で着脱自在に取り付けられる。
吊り具３は、レール２の吊り具取付面１２（支持壁６外面）に接当するベース部材１３と、このベース部材１３に対して吊り具取付面１２に直交する方向の回転軸心Ｘ回りに回転自在な支持部材１４と、この支持部材１４に取り付けられたフック部材１５と、前記支持壁６の背面側（支持壁６内面側）に位置していて前記ベース部材１３とで一対の支持壁６を挟み込むことによりレール２に対して吊り具３を取付固定する係止部材１６と、この係止部材１６を支持部材１４に取り付ける取付軸１７と、フック部材１５の取付部分を覆うキャップ部材１８とを備えている。
【００１７】
なお、フック部材１５は、紐等の引掛け部材を引っ掛ける側を正面側Ａといい、その反対側を背面側Ｂという。
ベース部材１３は円板状に形成され、その中心が支持部材１４の回転軸心Ｘと同心状とされていると共に、中心側に回転軸心Ｘを中心とする円形の挿通孔２０が形成されている。
また、ベース部材１３の、レール２の支持壁６外面に接当する接当面２１は、該接当面２１側の他の部分２２（レール２の開口部８に対応する部分）よりも一段凹むように凹設されていて、前記他の部分２２、すなわちベース部材１３の接当面２１間が、レール２の開口部８に挿入状とされる突出部２２とされており、この突出部２２がレール２の開口部８に嵌まることにより、ベース部材１３が、レール２に対して支持部材１４の回転軸心Ｘ回りに回り止めされている（図４及び図５参照）。
【００１８】
支持部材１４は、回転軸心Ｘ方向一端側の本体部２４と、回転軸心Ｘ方向他端側のフック取付部２５とを有する。
本体部２４は、外面が段付き状の円柱状に形成され、回転軸心Ｘ方向一端側が径小で他端側が径大とされている。
また、この本体部２４の中心部には、回転軸心Ｘと同心状のネジ孔２６が形成されていると共に、本体部２４の回転軸心Ｘ方向一端側には、前記ネジ孔２６に連通し且つネジ孔２６よりも径大な円形の嵌合凹部２７が形成されている。
【００１９】
この本体部２４の径小部分２４ａは前記ベース部材１３の挿通孔２０を挿通していると共に、本体部２４の径大部分２４ｂは挿通孔２０を挿通不能とされており、ベース部材１３に対して支持部材１４が回転軸心Ｘ回りに回転自在とされている。
また、支持部材１４のフック取付部２５は、回転軸心Ｘ方向に直交する方向で対向する一対の取付壁２９を備えている。
また、支持部材１４の外面の、本体部２４とフック取付部２５との接続部分には、フランジ部３０が径方向外方に突出状に設けられている。
【００２０】
また、支持部材１４の回転軸心Ｘ方向一端側には、回転軸心Ｘ方向に直交する方向で対向する一対の規制壁３１が設けられており、この一対の規制壁３１の対向方向は前記一対の取付壁２９の対向方向と同じ方向とされている。
前記フック部材１５の基部１５ａは、フック取付部２５の取付壁２９間に挿入され、一方の取付壁２９から他方の取付壁２９にわたって貫通されて設けられた（回転軸心Ｘ方向に直交する方向（取付壁２９の対向方向））に設けられた枢軸３２によって回転自在に枢着されている。
【００２１】
これによって、フック部材１５は支持部材１４から回転軸心Ｘ方向に沿う方向に突出状とされた状態（図７に仮想線で示す状態）から、背面側Ｂ（図７（ａ）参照）と正面側Ａ（図７（ｂ）参照）とに倒れ得るように設けられている（支持部材１４から回転軸心Ｘ方向に沿う方向に突出状とされた状態から、背面側Ｂと正面側Ａとに略９０°回転可能とされている）。
図４及び図５に示すように、係止部材１６は板材等から形成され、ベース部材１３の一方の接当面２１から他方の接当面２１に亘る長さＬに形成され、幅Ｗは、レール２の支持壁６端面間の間隔よりも狭幅に形成されていて、該係止部材１６が開口部８からレール溝７内に挿脱自在に挿入可能とされている。
【００２２】
また、係止部材１６の中心部（長さＬ方向及び幅Ｗ方向の中央部）には、支持部材１４の嵌合凹部２７と略同径の円形の挿通孔３３が厚さ方向貫通状に形成されている。
また、この係止部材１６の長さＬ方向の中央側の幅は、支持部材１４の一対の規制壁３１間に挿入可能な幅に形成されていて、この係止部材１６の長さＬ方向中央側は規制壁３１間に嵌め込まれている。
これによって、係止部材１６が支持部材１４と回転軸心Ｘ回りに一体回転自在とされており、支持部材１４と共に係止部材１６を回転することにより、係止部材１６が、開口部８を通過可能な姿勢と、開口部８を通過不能な姿勢とに姿勢変更自在とされている。
【００２３】
取付軸１７は、頭部３５と、該頭部３５から軸心方向に突出していて係止部材１６の挿通孔３３を挿通して支持部材１４の嵌合凹部２７に嵌合する軸部３６と、この軸部３６から軸心方向に突出していて支持部材１４のネジ孔２６に螺合するネジ部３７とを備えており、この取付軸１７によって、ベース部材１３及び係止部材１６が支持部材１４に対して抜け止めされている（取り付けられている）。
また、取付軸１７の頭部３５と係止部材１６との間にはバネ部材３８が介装されていて、係止部材１６がベース部材１３側に付勢されている。
【００２４】
前記キャップ部材１８は、フック部材１５の取付部分及び支持部材１４の本体部２４の径大部分２４ｂ並びにフランジ部３０を覆うように形成されている。
また、このキャップ部材１８には、支持部材１４のフランジ部３０に係合して該キャップ部材１８の、支持部材１４からの外れ止めをする係合部３９（係合爪）が設けられていると共に、該キャップ部材１８は支持部材１４に対して回転軸心Ｘ回りに相対回転自在とされている。
また、キャップ部材１８には切欠き溝４０が形成されており、図３（ａ）に示すように、吊下げ装置１が壁９に取り付けられた状態において、フック部材１５が支持部材１４から回転軸心Ｘに直交する方向で且つ下方に垂れ下がる姿勢（壁取付姿勢）と、図３（ｂ）に示すように、吊下げ装置１が天井１０に取り付けられた状態において、フック部材１５が支持部材１４から回転軸心Ｘに沿う方向で且つ下方に垂れ下がる姿勢（天井取付姿勢）とに姿勢変更自在とされている。
【００２５】
前記構成の吊下げ装置１において、壁９に取り付けられたレール２に吊り具３を取り付ける場合にあっては、先ず、図４に仮想線で示すように、係止部材１６がベース部材１３の突出部２２の幅内に納まるように（係止部材１６がベース部材１３の突出部２２に沿うように）支持部材１４を回転させて位置合わせすると共に、フック部材１５を回転軸心Ｘ方向に沿う方向に突出する状態から背面側Ｂに倒した壁取付姿勢とし、この状態で図６（ａ）及び図４の仮想線に示すように、係止部材１６及びベース部材１３の突出部２２をレール２の開口部８からレール溝７内に挿入すると共に、ベース部材１３の接当面２１を支持壁６の外面に接当させる。
【００２６】
この状態で、フック部材１５はレール２の長手方向に沿う状態とされており、次に、フック部材１５を下方（図６（ａ）の矢示Ｄ方向）に略９０°揺動させると、係止部材１６は支持部材１４と共に、図４の矢示Ｃ方向に回転し、図１、図４の実線及び図６（ｂ）に示すように、レール２の支持壁６が吊り具３のベース部材１３と係止部材１６とで挟持され、該吊り具３がレール２に取付固定される。
また、天井１０に取り付けられたレール２に吊り具３を取り付ける場合にあっては、図７（ａ）に実線で示すように、フック部材１５が背面側Ｂに倒れている場合（壁取付姿勢とされている場合）は、図７（ｂ）に示すように、フック部材１５を枢軸３２回りに略９０°回転させて起こし、支持部材１４から回転軸心Ｘ方向に沿う方向に突出した状態とする（天井取付姿勢とする）。
【００２７】
次に、図７（ｂ）に示すようにキャップ部材１８を回転軸心Ｘ回りに１８０°回転させると、フック部材１５が正面側Ａに倒せるようになるので、該フック部材１５を正面側Ａに倒す（フック部材１５を正面側Ａに枢軸３２回りに略９０°回転させる）。
次に、図８（ａ）に示すように、係止部材１６がベース部材１３の突出部２２に沿う状態で係止部材１６及びベース部材１３の突出部２２をレール２の開口部８からレール溝７内に挿入すると共に、ベース部材１３の接当面２１を支持壁６の外面に接当させる。
【００２８】
次に、前記状態からフック部材１５を回転軸心Ｘ回りに略９０°回転させる。
すると、吊り具３は、図８（ｂ）に示す状態となり、さらに、この状態からフック部材１５を下方に枢軸３２回りに略９０°回転させると、図８（ｃ）に示すように、フック部材１５が天井取付姿勢となる。
また、この状態では、キャップ部材１８の切欠き溝４０が手前にあり、見栄えが悪いので、キャップ部材１８を回転軸心Ｘ回りに略１８０°回転させてもとに戻し、図８（ｄ）に示す状態とする。
【００２９】
この天井１０に取り付けられたレール２に吊り具３を取り付ける場合にあっては、フック部材１５が天井取付姿勢とされた状態で、吊り具３の係止部材１６及びベース部材１３の突出部２２をレール２の開口部８からレール溝７内に挿入した後、フック部材１５を回転軸心Ｘ回りに略９０°回転させるという取付方法も考えられるが、このようにすると、レール２を天井１０に取り付ける場合、該レール２は壁９際に取り付けられることが多く、壁９際でフック部材１５を指でつまんで回転させるという操作がし難いこと、及び、係止部材１６を回転させてレール２の支持壁６を該係止部材１６とベース部材１３とで挟持する際のフック部材１５の回転操作は比較的固いことから、この取付方法では、吊り具３の取り付けが困難である。
【００３０】
そこで、前述したように、図８（ａ）に示すように、フック部材１５を正面側Ａに倒し且つレール２の長手方向に沿わせた状態でフック部材１５の先端側を指でつまんで（又は引っ掛けて）、手前に回転させるという操作でレール２に吊り具３を取り付けることにより、吊り具３の取付操作が容易に取り付けることができるのである（吊り具３を比較的軽い力で取り付けることができるのである）。
なお、キャップ部材１８は吊り具３をレール２に取り付けた後に、支持部材１４に取り付けることもできる。この場合、キャップ部材１８を支持部材１４に対して回転自在な構造としなくてもよい。
【００３１】
また、前記構成の吊り具３にあっては、フック部材１５を、天井取付姿勢にした位置と、壁取付姿勢にした位置と、正面側Ａに倒した位置の各位置で位置決めする位置規制手段、及び、係止部材１６を、ベース部材１３の突出部２２に沿う位置（図４の仮想線で示す位置）と、該位置から回転軸心Ｘ回りに略９０°回転させた位置（図４の実線で示す位置）の各位置で位置決めする位置規制手段を備えているのがよい。
【００３２】
【発明の効果】
本発明によれば、レール溝の開口部が下を向く状態で天井に設けられたレールに対して、吊り具のフック部材を正面側に倒した状態で且つ該フック部材がレールの長手方向に沿う状態で、吊り具の係止部材を開口部からレール溝内に挿入すると共に吊り具のベース部材をレールの支持壁に接当させ、その後、フック部材の先端側を指でつまんで（又は引っ掛けて）回転させて、係止部材とベース部材とでレールの支持壁を挟持することにより、吊り具がレールに取り付けられるように構成することによって、天井に取り付けられたレールに吊り具を容易に取り付けることができる。
【００３３】
また、特に、フック部材の支持部材への取付け部分を覆うキャップ部材を設けると共に、このキャップ部材に、フック部材の、天井取付姿勢から壁取付姿勢への姿勢変更を許容するための切欠き溝が形成されたものにあっては、キャップ部材を支持部材に回転軸心回りに回転自在に取り付けることにより、切欠き溝によって、フック部材を、天井取付姿勢から正面側へ回転させて倒すことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a suspending device for suspending a picture or various exhibits on a wall or ceiling.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there is a hanging device in which a hanging tool is detachably attached to a rail attached to a wall or a ceiling (see Patent Document 1).
In this suspension device, the rail is configured by forming an opening in the longitudinal direction of the rail in one wall portion of a rectangular cylindrical tube body, and the opening side is a suspension attachment surface. On the fixture mounting surface side, there is a pair of support walls so as to sandwich the opening, and the wall portion facing the lifting fixture mounting surface is a mounting wall for mounting and fixing the rail to the wall or ceiling.
[0003]
On the other hand, the lifting tool can be inserted into the inner rail groove from the opening of the rail, and is rotated 90 ° around the rotation axis in the direction perpendicular to the mounting surface of the lifting tool to contact the back side of the support wall. A retaining block that can be applied, a hook member for hooking a hook member such as a string, and an axial center that is provided between the retaining block and the hook member and is concentric with the rotational axis of the retaining block A bolt member, a nut member screwed onto the outer surface of the bolt member, a flat washer provided on an end surface of the nut member, and a coil spring housed inside the nut member.
[0004]
In this hanging device, after the retaining block is inserted into the rail groove from the opening, the retaining block is rotated by 90 ° so that the retaining block contacts the back side of the support wall of the rail. Then, by tightening the nut member, the support wall of the rail is sandwiched between the retaining block and the flat washer, so that the suspension is attached and fixed to the rail.
The hook member is fixed to the bolt member so that the posture can be freely changed between a ceiling mounting posture protruding in a direction along the axis of the bolt member and a wall mounting posture rotated 90 ° from the ceiling mounting posture to the back side. It is pivotally attached to the mounting part.
[0005]
In this suspension device, the nut member is fastened to fix the suspension to the rail, so that there is a problem that the operation of rotating the nut member is complicated and troublesome.
Therefore, there is a suspending device in which a suspender can be attached to a rail with one touch (see Patent Document 2).
The suspension device of the suspension device includes a base member that contacts the suspension attachment surface of the rail, a support member that is rotatable about a rotation axis in a direction perpendicular to the suspension attachment surface with respect to the base member, A hook member that is fixedly attached to the support member, and a locking member that is located in the rail groove and that attaches and fixes the suspension to the rail by sandwiching the support wall with the base member. The locking member is rotatable together with the support member. By rotating the support member, the posture of the locking member can be changed to a posture in which the locking member can be inserted into and removed from the rail groove from the opening.
[0006]
In this suspension device, the locking member is inserted into the rail groove from the opening of the rail, and the base member is brought into contact with the outer surface of the support wall (hanging device mounting surface). The support wall of the rail is clamped between the lock member and the base member by rotating the support member together with the support member by 90 ° around the rotation axis so that the lock member contacts the back side of the support wall. It is configured to be fixed to the rail with a single touch.
The suspension device of the suspension device is fixed to the support member as a protruding shape in a direction orthogonal to the rotation axis direction from the support member, and is dedicated to wall mounting attached to a rail fixed to the wall. Has been.

Japanese Patent Laid-Open No. 5-80365
[Problems to be solved by the invention]
In the suspension device of the suspension attachment structure of Patent Document 2, when the suspension is attached to a rail fixedly attached to the ceiling, the hook member protrudes from the support member in a direction along the rotational axis direction. To be fixed to the support member.
In this case, the rail is attached to the ceiling so that the opening portion faces downward, and the suspension tool inserts the locking member into the rail groove from the lower side through the opening portion, and the tip end side of the hook member with a finger. It is attached to the rail by pinching and rotating 90 ° around the axis of rotation.
