Description

【０００１】
【発明の属する技術分野】
本発明は、建造物室内の空調設備における吹出口とダンパ−装置の一体支持装置に関するものである。
【０００２】
【従来の技術】
従来、建築構造物の空調設備において、図４に示すように天井裏空間Ｔ内に例えば天井ボ−ドＵに配置させたアネモ型の吹出口ＡとフレキシブルダクトＦを連結し、このフレキシブルダクトＦの中途位置にダンパ−装置Ｄを介装して前記吹出口Ａから室内に供給する空気の量を調整するものであった。そして一般的にこのダンパ−装置Ｄは騒音を伴うため吹出口Ａからある程度離隔させた位置に配置され、吊支部材Ｘによって吊支されるものであった。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記の従来の吹出口Ａ回りの支持部においては吹出口Ａとダンパ−装置Ｄが離隔されて配置されているから、それぞれを別個の吊りボルト等の吊支部材により天井スラブＳから吊支し、前記吹出口Ａとダンパ−装置ＤとをフレキシブルダクトＦ等で連結しなければならず施工作業が繁雑で時間がかかるという問題があった。また、天井ボ−ドＵには、天井裏内のダンパ−装置Ｄの保守点検のために前記吹出口Ａの取付開口部の他にダンパ−装置Ｄ専用の点検口Ｃを設ける必要があり、また点検口Ｃを設けない場合には前記開口部から天井裏空間Ｔ内に入って狭い空間で作業を行なわなければならずダンパ−装置Ｄ等の保守点検作業が繁雑で効率が悪く、また、作業コストがかかるものであった。さらに、前記点検口Ｃを設けることで天井ボ−ドＵの意匠感を損なう問題があった。また、吹出口ＡとフレキシブルダクトＦとダンパ−装置Ｄは別個に設置し、保守点検も離隔場所で行うから、例えば運搬時等に部品の紛失や施工作業現場での部品点数の不足等の人的なミスが発生し、施工作業の円滑な実施を妨げるものであった。
【０００４】
本発明は、上記従来の問題点に鑑みてなされたものであり、その目的は、空気吹出口、ダンパ−装置、その他のセンサ−類を一体的に取り扱え、天井裏内への空気吹出口、ダンパ−装置、その他のセンサ−類の取付施工が簡単であるとともにこれらの保守点検を能率よく行うことができる吹出口とダンパ−装置の一体支持装置を提供することにある。
【０００５】
【課題を解決するための手段】
上記目的を達成するために本発明は、天井裏内の天井スラブ面等から吊支部材により吊支される支持フレ−ム１２と、同支持フレーム１２の少なくとも一箇所に固定されたダンパー装置１４と、支持フレーム１２に一部を支持されつつ一端側を垂下させて下部側の吹出口１８に接続されるフレキシブルダクト１６と、を有し、吹出口１８を天井開口３８にあてがって嵌合させた位置で吊支状に支持し得る状態と、吹出口１８をフレキシブルダクト１６から取りはずして、該フレキシブルダクト１６の端部を天井開口３８から離隔位置に支持する状態と、を選択的に変更支持自在な変更支持装置２０が設けられ、変更支持装置２０は、一端側を支持フレ−ム１２に枢着されるとともに他端側をフレキシブルダクト１６の吹出口１８との接続側となる端部に枢着され、支持フレーム１２の枢着部分回りにフレキシブルダクト１６を回動させて支持フレーム１２と略平行状になるように変位支持させる揺動ア−ム４２、を含む吹出口とダンパ−装置の一体支持装置から構成される。
【０００６】
また、揺動アーム４２は、支持フレ−ム１２に取り付けられた軸支部材４０に一端側を枢着軸支され、フレキシブルダクト１６の長手方向に沿う様にして同フレキシブルダクト１６を内側にはさみ込む様に配置され、かつ他端部をフレキシブルダクト１６の吹出口１８との接続側端部に枢着された２本のア−ム体４４からなることとしてもよい。
【０００７】
また、変更支持装置２０は、揺動アーム４２を介してフレキシブルダクト１６の吹出口１８との接続側端部を回動させてフレキシブルダクト１６を支持フレーム１２と略平行状態になる位置まで変位させた状態で該フレキシブルダクト１６の吹出口との接続側端部を係止させる係止部材４６を含むこととしてもよい。
【０００８】
また、係止部材４６は支持フレーム１２に取り付けられたＬ字状部材を含み、フレキシブルダクト１６の吹出口１８との接続側端部の内側を乗せ掛けた状態で係止させることとしてもよい。
【０００９】
【発明の実施の形態】
本発明に係る吹出口とダンパ−装置の一体支持装置は、天井裏内の天井スラブ面等から吊支部材により吊支される支持フレ−ムと、同支持フレ−ムの少なくとも一カ所に固定されたダンパ−装置と、中間にフレキシブルダクトを介設して連通接続された吹出口と、を有し、前記支持フレ−ム及び又は前記フレキシブルダクトには、前記吹出口を天井開口にあてがって嵌合させた位置で吊支状に支持し得る状態と、前記吹出口を前記フレキシブルダクトから取りはずして、該フレキシブルダクトの端部を前記天井開口から離隔位置に支持する状態と、を選択的に変更支持自在な変更支持装置を備えて構成される。変更支持装置は、例えば支持フレ−ムに、その長手方向に沿って移動可能に吊支部を設け、この吊支部にフレキシブルダクトを貫通状に遊挿させた環状の吊支部材を吊支させ、この環状吊支部材の横移動により同フレキシブルダクト端部を変位させることとしてもよい。また変更支持装置の係止部とフック体は、支持フレ−ム側又はフレキシブルダクト側のいずれの側に設けてもよい。
【００１０】
また、前記変更支持装置は、一端を前記支持フレ−ムに枢着されるとともに、他端側を前記フレキシブルダクトの端部に枢着された揺動ア−ムを含むこととしてもよい。揺動ア−ムは、長手方向に伸縮自在性をもたせてもよい。揺動ア−ムは、例えば電動モ−タ−等の動力によって支持フレ−ムの枢着部分を軸として支持フレ−ムの長手方向に沿うように回動することとしてもよい。揺動ア−ムは、変形、復元可能な金属線条でもよい。また、ア−ムをリンク式に関節を備えた構成としてフレキシブルダクト端部の変位及び位置保持の機能を円滑に行なわせるようにしてもよい。変更支持装置は、支持フレ−ム側に係着部を作っておいて、揺動ア−ムをダクト端部のみに枢着し、ア−ム先端側を支持フレ−ムの係着部に係着させて支持する様にしてもよい。
【００１１】
また、前記揺動ア−ムは、２本のア−ム体からなり、前記変更支持装置は、前記支持フレ−ムに取り付けられた軸支部材と、この軸支部材に枢着軸支され、前記フレキシブルダクトの長手方向に沿う様にして同フレキシブルダクトを内側にはさみ込む様に配置され、かつ他端部を前記フレキシブルダクトの端部に枢着された前記２本のア−ム体と、からなることとしてもよい。ア−ム体と軸支部材の枢着部分を軸として例えばア−ム体の長手方向が支持フレ−ムの長手方向と略直交する位置と、ア−ム体の長手方向が支持フレ−ムの長手方向と略平行になる位置と、これらの前記位置の略中間位置とを段階的に回動する機構を設けてもよい。また、ア−ム体は、例えばバネ部材等の弾性部材で常にフレキシブルダクト端部の揺動方向に付勢してもよく、例えばダンパ−装置等の保守点検を行なう際に、ロックを外して付勢力によりア−ム体を自動的に回動させてフレキシブルダクト端部を作業すべき空間から移動させ、その状態を保持させて能率よく保守点検作業を行なえる。
【００１２】
また、前記支持フレ−ムには、前記フレキシブルダクト端部を前記天井開口から離隔した位置で係脱自在に係着する係止部材が設けられてなることとしてもよい。係止部材は、フレキシブルダクト端部に設けたフック体でもよく、このフック体を支持フレ−ム側に設けた係止部と係止させることによってフレキシブルダクト端部を前記天井開口から離隔した位置で保持する。
【００１３】
【実施例】
以下、添付図面に基づき、本発明の好適な実施例を説明する。図１、２、３には、本発明の実施例に係る吹出口とダンパ−装置の一体支持装置（以下、「支持装置」という。）１０が示されている。図より明らかな様に、支持装置１０は、例えば天井裏内の天井スラブ面等から吊支部材により吊支される支持フレ−ム１２と支持フレ−ム１２の少なくとも一カ所に固定されたダンパ−装置１４と中間にフレキシブルダクト１６を介設して連通接続された吹出口１８とを有し、さらに支持フレ−ム１２には変更支持装置２０が設けられている。
【００１４】
図１、２において支持フレ−ム１２は、構造物躯体の天井裏空間Ｔ内に配置され、天井スラブＳに取り付けられた吊支部材２２によって吊支されている。本実施例において吊支部材２２は、上端を天井スラブＳに固定させた２本の吊支用長ボルト２４、２４である。
【００１５】
これらの吊支用長ボルト２４、２４は、支持フレ−ム１２の両端部寄り部分を吊支し得る位置に配置され、同吊支用長ボルト２４、２４の下端部に支持フレ−ム１２をナット部材２６で取付け固定している。本実施例にかかわらず支持フレ−ムの天井スラブ等への取り付け方法は、天井スラブに取り付けた３、４ないし複数本の吊支部材２２によって吊支してもよく、その他任意の取り付け方法を行なってもよい。
【００１６】
図１において、吊支部材２２には１本の支持フレ−ム１２が横長状となる様に吊支されている。この支持フレ−ムに１２は、切断面が下向きに開口を有した略コ字状でレ−ル状に長く形成されている。支持フレ−ム１２の上板面の両端部寄りには長孔２７、２７がそれぞれ開孔されており、これらの長孔２７、２７に各吊支用長ボルト２４、２４を挿通させ、ナット部材２６によって固定している。本実施例において支持フレ−ム１２は、例えばある程度の強度と耐食性を備えた金属板を折り曲げて一体的に形成されている。本実施例にかかわらず支持フレ−ムの素材や形状、長さは、後述するダンパ−装置と変更支持装置を取り付け得るものとして任意に形成させてもよい。例えば平面視略格子状に組み付けたもの、平面板状、筒状、柱状、円形、角形、その他任意の構成としてもよい。
【００１７】
図１、２において支持フレ−ム１２の後端部寄り位置の下面側にはダンパ−装置１４が図示しないボルト部材によって固定されて取り付けられている。このダンパ−装置１４は、例えば建造物室内等へ供給する空気の量等を調整する。通常はこのダンパ−装置１４は、風量調整用である場合が多いが、その他防火、防煙用のシャッタ機構を備えたもの、定風量機構を備えたもの、その他任意のダンパ−装置でもよい。実施例においてダンパ−装置１４は、室内の空調状態をセンサ−で感知しながら最適の風量を室内に送る風量可変のＶＡＶダンパ−（ＶａｒｉａｂｌｅＡｉｒＶｏｌｕｍｅＤａｍｐｅｒ）装置である。実施例において特に羽根の開閉によっても騒音が極めて少ない羽根表面に布や植毛を張設させたスライド羽根形の低騒音ダンパ−が用いられる。したがって、吹出口とダンパ−装置とは近接位置に配置させ、これらを一体的に組み付けて吹出口近傍に設置しても室内への影響は少ない。
【００１８】
いずれにしてもダンパ−装置としては、空気の流れ等によって発生する騒音が少ないものが好適である。ダンパ−装置の支持フレ−ムへの取り付けは、溶接固定したり、支持フレ−ム側に設けたスライド溝にダンパ−装置に取り付けたボルト部材を突入係合させてスライドさせ、任意の位置でナット等で固定させる様にしてもよい。また、予め支持フレ−ムとダンパ−装置を一体的に形成してもよい。
【００１９】
図１、２に示す様にダンパ−装置１４の一端は、フレキシブルダクト１６に接続されている。フレキシブルダクト１６は、略円形の切断面を有するとともに同フレキシブルダクト１６の側壁面は例えばグラスウ−ル等の不燃性の断熱部材３２で被覆され、長手方向にアコ−ディオン状に伸縮自在であるとともに、断面の中心位置から半径方向にずれる方向にも変形できるようになっている。尚、ダンパ−装置１４の他端側には、例えば施工時に直管ダクトやフレキシブルダクトが接続され、送風機等に連通するようになっている。
【００２０】
図においてフレキシブルダクト１６は、一端をダンパ−装置１４に連通接続させ、他端部は室内側に空気を吹き出す吹出口に連通接続させるに足る長さである。このフレキシブルダクトのダンパ−装置との接続側と他端部側の円形開口縁には接続用環部材３４が嵌着固定されている。接続用環部材３４は、例えば亜鉛メッキや塗装を施した鋼板等のある程度の強度と耐食性を備えた帯状金属板をリング状に曲げて形成されており、同接続用環部材３４の板面に枢着部３６を設けている。
【００２１】
図１に示す様に枢着部３６は、接続用環部材３４の略直径位置となる両側２箇所に配置されている。そしてこれらの枢着部３６には、後述するア−ム体の一端側がフレキシブルダクト１６を両外側から内側に挟み込む様に配置されて枢着されている。この接続用環部材３４には吹出口１８が取り付けられている。本実施例において吹出口１８は、送気用の開口を下方に向けてラッパ状に拡開したアネモ型の吹出口である。図１において吹出口１８は、図２に示す天井開口３８に建造物室内側から挿嵌されて天井ボ−ドＵに固定されている。吹出口は、内部に風向調整機構を有したものでもよい。
【００２２】
実施例において支持フレ−ム１２の略中央寄り位置とフレキシブルダクト１６の接続用環部材３４には、変更支持装置２０が設けられている。図１に示す様に変更支持装置２０は、支持フレ−ム１２に取り付けられた軸支部材４０と、この軸支部材４０に設けられた揺動ア−ム４２を備えている。図２に示す様に軸支部材４０は、支持フレ−ム１２を天井スラブＳへ吊支させた状態で天井開口３８の真上位置となる支持フレ−ム１２に取り付けられている。
【００２３】
この軸支部材４０には揺動ア−ム４２の一端が枢着軸支されている。本実施例において揺動ア−ム４２は、例えば鋼板を長板状に形成した２本のア−ム体４４、４４からなる。また、これらのア−ム体４４、４４は、フレキシブルダクト１６の長手方向に沿うようにして同フレキシブルダクト１６を内側に挟み込むように配置されている。
【００２４】
フレキシブルダクトは、２本のア−ム体によってはさみ込まれて配置され支持されているから、特にア−ム体の揺動時にも前記フレキシブルダクトの端部が同ア−ム体によって支持力が偏ることなく支持され、同フレキシブルダクトを損傷するようなことがない。また、揺動操作の際の動きも安定するから迅速に動かすことができ、吹出口、ダンパ−廻りの支持作業効率を大幅に向上させることとなる。
【００２５】
ア−ム体４４、４４の他端部は、接続用環部材３４の枢着部３６において枢着されている。これによって、接続用環部材３４を取り付けた側であるフレキシブルダクト１６の端部を図２の矢印（イ）、（ロ）に示す方向に回動可能に吊支する。ア−ム体４４、４４は、図２に示すように吹出口１８を取り外したフレキシブルダクト１６の前記端部を矢印（イ）方向に揺動して同フレキシブルダクト１６が支持フレ−ム１２と略平行状態になる位置まで変位させる。
【００２６】
ここにおいて、変更支持装置２０は、吹出口を天井開口にあてがって嵌合させた位置で吊支状に支持し得る状態と、吹出口をフレキシブルダクトから取りはずして、フレキシブルダクトの端部を天井開口から離隔位置に支持する状態とを選択的に自在に変更支持する。このようにフレキシブルダクトの端部は、揺動ア−ムを操作するだけで揺動させることができるから、同フレキシブルダクト端部の変更支持作業を簡単に行なえる。
【００２７】
本実施例にかかわらず揺動ア−ムは、１本のア−ム体でもよく一端を支持フレ−ムに枢着するとともに他端側をフレキシブルダクトの接続用環部材に枢着していれば変更支持が円滑に実現できる。このように変更支持装置は、揺動ア−ムを支持フレ−ムと接続用環部材に枢着するだけでよいから簡単な構造で装置を実現でき製造も短時間で容易に行うこととなる。また、変更支持装置は、簡単な構造であることにより製造設備を簡略化でき製造コストを低廉に抑えることとなる。
【００２８】
本実施例において支持フレ−ム１２には、係止部材４６が設けられている。図１において係止部材４６は、例えば支持フレ−ム１２の一端寄り側に設けられ、その長手方向に鈎ヅメ状に曲げて形成されている。この係止部材４６の上端部は図２に示す矢印（イ）、（ロ）方向に回動自在に支持フレ−ム１２に枢着されている。この係止部材４６は、図２に示すフレキシブルダクト１６の前記天井開口から離隔した位置で同フレキシブルダクト１６の端部に係着し得る位置に取り付けられており、この離隔位置でフレキシブルダクト１６端部の内壁に係着して同フレキシブルダクト１６端部を支持している。
【００２９】
本実施例にかかわらず係止部材は、クリップ部材、その他の係止部材等でもよく要は、フレキシブルダクト端部を天井開口から離隔した位置で係脱自在に係着するものであればよい。このように簡単な構造でフレキシブルダクト端部の天井開口からの離隔位置における支持を実現でき、例えば図３に示すように作業者が天井開口から半身を天井裏内にのり出した状態での簡易で迅速な取付、保守、点検作業を実現することとなる。
【００３０】
上記したように本発明にかかる支持装置１０は、ダンパ−装置と、中間にフレキシブルダクトを介設して連通接続された吹出口と、吹出口を天井開口にあてがって嵌合させた位置で吊支状に支持し得る状態と、前記吹出口を前記フレキシブルダクトから取りはずして、該フレキシブルダクトの端部を前記天井開口から離隔位置に支持する状態と、を選択的に変更支持自在な変更支持装置を支持フレ−ムを連結の基本として一体的に備えることにより、作業者は例えば天井裏内の天井スラブ面等から吊支部材によりこの支持装置を吊支するだけで吹出口と前記フレキシブルダクトとダンパ−装置を一気に天井裏内に取り付けることができるので、吹出口と前記フレキシブルダクトとダンパ−装置の取付作業時間を大幅に短縮することができ建造物への空調設備の取付施工作業全体を能率よく行うこととなる。また、この吹出口と前記フレキシブルダクトとダンパ−装置は一体的に取り扱うので、例えば運搬時等の部品の紛失を防止したり、施工作業現場での部品点数の不足等の人的なミスを防止し、確実で円滑な施工作業を行える。
【００３１】
また、ダンパ−装置の保守点検作業時においては、保守点検作業者はこの天井開口から天井裏内に半身をのりだして入るだけで吹出口ないしダンパ−装置の保守点検作業が可能となり、作業効率が大幅に向上し、保守点検作業を短時間で終了することとなる。また、天井開口以外の天井裏内への入口が不要となるので、例えば天井ボ−ド等への点検口の取付施工作業を省略でき空調設備全体の施工作業を短時間で終了することができるとともに天井面の意匠感も良好に保持することとなる。
【００３２】
次に、本発明に係る支持装置１０の作用を説明する。図１、２、３において構造物躯体の天井裏空間Ｔ内に配置され、天井スラブＳに取り付けられた吊支部材２２によって吊支された支持装置１０が示されている。
【００３３】
図１において支持装置１０は、支持フレ−ム１２にダンパ−装置１４、フレキシブルダクト１６、吹出口１８、及び変更支持装置２０を取り付けた物を１つの単位とし、この単位ごとに例えば構造物建築作業現場等にトラック等の輸送車によって運搬される。そして、作業現場において作業者は、例えば図１に示す構造物躯体の天井スラブＳに埋設したアンカ−に吊支用長ボルト２４、２４を取り付け、この長ボルト２４、２４に支持装置１０を取り付ける。この時、フレキシブルダクト１６は、一端側がダンパ−装置１４に連通接続され同ダンパ−装置１４によって支持されている。同時にフレキシブルダクト１６の他端側は、開口が下向きになる様にア−ム体４４によって吊支状に支持されている。この状態で作業者は、天井ボ−ドＵを構造物の天井部分に取り付け、吹出口１８を図２に示す天井ボ−ドＵの天井開口３８にあてがって前記フレキシブルダクト１６の端部に嵌合連接させ、支持装置１０の取り付け施工作業を行なう。
【００３４】
この様に、作業者は例えば天井裏内の天井スラブ面等から吊支部材によりこの支持装置を吊支するだけで前記吹出口ないしダンパ−装置を一気に天井裏内に取り付けることができ取付作業時間を大幅に短縮することとなる。また、ダンパ−装置、フレキシブルダクト、吹出口、および変更支持装置は支持フレ−ムに取り付けられた状態で例えば工場から上記したような作業現場まで運搬されるので、運搬時等の部品の紛失を防止したり、施工作業現場での部品点数の不足等の人的なミスを防止し、確実で円滑な施工作業を行うこととなる。
【００３５】
図１に示す様に通常の支持装置１０の使用状態でア−ム体４４、４４は、天井ボ−ドＵに取り付け固定された吹出口１８と嵌合したフレキシブルダクト１６端部の接続用環部材３４を支持している。すなわち、変更支持装置２０は、吹出口１８を図２に示す天井開口３８にあてがって嵌合させた位置で支持している。
【００３６】
天井裏空間Ｔ内に取り付けられた支持装置１０の保守点検を行なう際には、図３に示す様に保守点検作業者は、フレキシブルダクト１６端部及び天井ボ−ドＵから吹出口１８を取り外し、ア−ム体４４、４４を図２に示す矢印（イ）方向に回動させてフレキシブルダクト１６の端部を保守点検作業のじゃまにならない位置まで揺動して支持する。フレキシブルダクト１６が前記略平行状態になった時点でこのフレキシブルダクト１６の端部を係止部材４６で係止し、該フレキシブルダクト１６の端部を天井開口３８から離隔位置に支持する状態を保持させる。このときフレキシブルダクト１６は、図２、３に示すように支持フレ−ム１２の長手方向に沿って略平行状態でア−ム体４４、４４と係止部材４６によって支持されている。
【００３７】
図３において作業者は、フレキシブルダクト１６の端部を天井開口３８から離隔位置に揺動して作業のための空間を確保した後に天井開口３８から天井裏空間Ｔ内に入り、天井裏空間Ｔ内に半身をのり出した状態でダンパ−装置１４やフレキシブルダクト１６等の保守点検を行なう。
【００３８】
この様に保守点検作業時には、フレキシブルダクト端部を前記天井開口から離隔位置に保持することにより同天井開口周りの障害物を取り除き空間を広く確保できるので、作業を容易に行なうことができ短時間で能率よく行なうこととなる。
【００３９】
本発明は上記した実施例構成にのみ限定されるものではなく、特許請求の範囲に記載した発明の本質を逸脱しないかぎりにおいて任意の改変を加えても良い。
【００４０】
【発明の効果】
以上説明した様に、本発明の吹出口とダンパ−装置の一体支持装置によれば、天井裏内の天井スラブ面等から吊支部材により吊支される支持フレ−ムと、同支持フレ−ムの少なくとも一カ所に固定されたダンパ−装置と、中間にフレキシブルダクトを介設して連通接続された吹出口と、を有し、前記支持フレ−ム及び又は前記フレキシブルダクトには、前記吹出口を天井開口にあてがって嵌合させた位置で吊支状に支持し得る状態と、前記吹出口を前記フレキシブルダクトから取りはずして、該フレキシブルダクトの端部を前記天井開口から離隔位置に支持する状態と、を選択的に変更支持自在な変更支持装置を備えてなることにより、支持フレ−ムは、吹出口、前記フレキシブルダクト、ダンパ−装置を備えているから、作業者は例えば天井裏内の天井スラブ面等から吊支部材によりこの支持装置を吊支するだけで前記吹出口ないしダンパ−装置を一気に天井裏内に取り付けることができ取付作業時間を大幅に短縮することができる結果、建造物への空調設備の取付施工作業全体を能率よく行うことができる。ダンパ−装置等の保守点検作業時においては、作業者は例えば天井開口から天井裏内に入るだけで吹出口ないしダンパ−装置の保守点検作業が可能となり、作業効率が向上し、保守点検作業を短時間で終了することができる。また、例えば天井ボ−ド等に前記保守点検作業用の点検口を設ける必要がなく、点検口の施工のためのコストもかからず天井ボ−ド等の意匠感を損なうことなく保守点検作業を行なうことができる。また、前記保守点検作業時には、フレキシブルダクト端部を前記天井開口から離隔位置に保持することにより同天井開口周りの障害物を取り除き、前記作業者は容易に、かつ円滑に天井裏内に入ることができ、点検保守作業を能率的に行なうことができる。また、この吹出口と前記フレキシブルダクトとダンパ−装置は一体的に取り扱うので、例えば運搬時等の部品の紛失を防止したり、施工作業現場での部品点数の不足等の人的なミスを防止し、確実で円滑な施工作業を行うことができる。また、前記天井開口以外の天井裏内への入口が不要となるので、支持装置の取付施工作業を簡略化でき短時間で作業を終了することができるとともに天井面の意匠感を保持することができる。
【００４１】
また、前記変更支持装置は、一端を前記支持フレ−ムに枢着されるとともに、他端側を前記フレキシブルダクトの端部に取り付けられた接続用環部材に枢着された揺動ア−ムを含むことにより、揺動ア−ムを支持フレ−ムと接続用環部材に枢着するだけでよいから簡単な構造で変更支持装置を実現でき製造も短時間で容易に行うことができる。また、簡単な構造であることにより製造設備を簡略化でき製造コストを低廉に抑えることができる。また、フレキシブルダクトの端部は、揺動ア−ムを操作するだけで揺動することができるから、同フレキシブルダクト端部の変更支持作業を簡単に行なうことができる。
【００４２】
また、前記揺動ア−ムは、２本のア−ム体からなり、前記変更支持装置は、前記支持フレ−ムに取り付けられた軸支部材と、この軸支部材に枢着軸支され、前記フレキシブルダクトの長手方向に沿う様にして同フレキシブルダクトを内側にはさみ込む様に配置され、かつ他端部を前記フレキシブルダクトの接続用環部材に枢着された前記２本のア−ム体と、からなることにより、変更支持装置を簡単に作ることができ、低コストで製造を行うことが可能であるとともにフレキシブルダクトは、２本のア−ム体にはさみ込まれるように配置されているからフレキシブルダクトを保護しつつ、特にア−ム体の揺動時にも偏りなく支持しているから、同フレキシブルダクトを損傷するようなことがない。また、揺動操作の際の動きも安定するから迅速に動かすことができ、吹出口、ダンパ−廻りの支持作業効率を大幅に向上させることが可能である。
【００４３】
また、前記支持フレ−ムには、前記フレキシブルダクト端部を前記天井開口から離隔した位置で係脱自在に係着する係止部材が設けられてなることにより、簡単な構造でフレキシブルダクト端部の天井開口からの離隔位置における支持を実現でき、例えば天井開口から半身を天井裏内にのり出した状態での簡易で迅速な取付、保守、点検作業を実現することが可能である。

BACKGROUND OF THE INVENTION
  The present invention relates to an integrated support device for an air outlet and a damper device in an air conditioner in a building room.
[0002]
[Prior art]
  Conventionally, in an air conditioner for a building structure, as shown in FIG. 4, an anemo-type air outlet A arranged in, for example, a ceiling board U and a flexible duct F are connected in a ceiling space T, and the flexible duct F The amount of air supplied from the outlet A to the room was adjusted by installing a damper device D in the middle position. In general, the damper device D is disposed at a position separated from the air outlet A to some extent because of noise, and is suspended by the suspension member X.
[0003]
[Problems to be solved by the invention]
  However, since the blower outlet A and the damper device D are spaced apart from each other in the conventional support portion around the blower outlet A, each is suspended from the ceiling slab S by a separate suspension member such as a suspension bolt. In other words, there is a problem that the air outlet A and the damper device D must be connected by a flexible duct F or the like, and the construction work is complicated and takes time. In addition, the ceiling board U needs to be provided with an inspection port C dedicated to the damper device D in addition to the mounting opening of the air outlet A for maintenance and inspection of the damper device D inside the ceiling. If the inspection port C is not provided, the work must be performed in a narrow space by entering the ceiling space T through the opening, and the maintenance and inspection work for the damper device D and the like is complicated and inefficient. The work cost was high. Furthermore, there is a problem that the design feeling of the ceiling board U is impaired by providing the inspection port C. In addition, the outlet A, flexible duct F, and damper device D are installed separately, and maintenance inspections are also performed at remote locations. For example, people who lost parts during transportation or have insufficient parts at the construction site. Mistakes occurred and hindered the smooth implementation of construction work.

As described above, since the end portion of the flexible duct can be swung only by operating the swing arm, the changing and supporting work of the end portion of the flexible duct can be easily performed.
[0027]
  Regardless of this embodiment, the swing arm may be a single arm body, and one end is pivotally attached to the support frame and the other end is pivotally attached to the connecting ring member of the flexible duct. Therefore, change support can be realized smoothly. In this way, the changed support device only needs to pivotally attach the swing arm to the support frame and the connecting ring member, so that the device can be realized with a simple structure and can be manufactured easily in a short time. . In addition, since the change support device has a simple structure, the manufacturing equipment can be simplified and the manufacturing cost can be reduced.
[0028]

The locking member 46 is attached to a position that can be engaged with the end of the flexible duct 16 at a position separated from the ceiling opening of the flexible duct 16 shown in FIG. The end of the flexible duct 16 is supported by engaging with the inner wall of the section.
[0029]
  Regardless of this embodiment, the locking member may be a clip member, other locking members, or the like, as long as the end of the flexible duct is detachably engaged at a position separated from the ceiling opening. With such a simple structure, it is possible to realize support at a position separated from the ceiling opening at the end of the flexible duct. For example, as shown in FIG. 3, the operator can easily support the half body from the ceiling opening in the ceiling. This will enable quick installation, maintenance, and inspection work.
[0030]
