Description

【０００１】
【発明の属する技術分野】
この発明は濾過器としても、篩器としても使用できる濾過器兼篩器に関する。
【０００２】
【従来の技術】
塗装用スプレーガンには塗料をガンに供給するカップが付属しているが、カップの容量は大きくても１立程度で少ないため、大量に塗装をする場合は何回もカップに塗料を補給しなければならず、補給に手間取り、塗装の作業効率が低下する。このため、バケツ式の提手を有する容量４立程度のホッパ形で、開閉コックを有する底の給液口に可撓チューブの一端部を連結し、塗装用スプレーガンからは付属のカップを外し、ガンのカップ取付口に上記チューブの他端部を連結し、提手を適宜のフックに引掛けて吊下げ、ガンに塗料を供給する通称ポリタンクを使用することが行われている。いずれの場合も、塗料のなかに異物が含まれていると、その異物がスプレーガンの中に浸入し、スプレーガンのノズルを詰まらせ、塗料をスプレーすることができなくなる。この傾向は、前日などに使い残した塗料を再使用する場合に多く発生する。こうなると塗装作業を中断し、スプレーガンを分解し、ノズルに詰まっている異物を除去しなければならず、非常に手数がかゝり、手も汚れる。
【０００３】
【発明が解決しようとする課題】
そこで、スプレーガンのカップや、前述のポリタンクなど容器の大きさに対応したメガホン形の紙製円錐筒の小径開口部を、濾布（メッシュ１００〜２００程度）を張って塞いだ使い捨て用濾過器が市販されているので、それを使用し、スプレーガンのカップやポリタンクに入れる塗料を濾過している。この濾過器は、メガホン形の紙製円錐筒の小径開口部に濾布を取付けて塞ぐのに手数がかゝるため比較的高価であり、１回使用しただけで捨てるのは省資源に反する。更に、濾過面積はメガホン形の円錐筒の小径開口部の開口面積に依存するので、円錐筒内に大径部から入れた塗料の全量を濾過し終わるまで非常に時間がかゝる。
【０００４】
【課題を解決するための手段】
本発明は、上述した問題点を解消し、篩器としても使用できる濾過器を提供するために開発されたもので、請求項１の濾過器兼篩器は、環状枠、上記環状枠から半径方向外向きに突出した把手を有する虫メガネ形の、同大の上フレーム及び下フレームと、上記上下の両フレームの重合した環状枠の間に周縁部を挟まれて支持される可撓な透過シートとからなり、上記下フレームの環状枠には外周側と内周側とに円周方向に一定の間隔を保って同心状の複数の外側弧状スリットと、内側弧状スリットとを設け、上フレームの環状枠の下面には上記外側弧状スリットと同心状で、同じ間隔を円周方向に保った複数の下向き突起と、内側弧状スリットと同心状で、同じ間隔を円周方向に保ち、上記下向き突起と位相を異にし、且つ下向き長さが上記下向き突起よりも短く、下向き突起が上記外側弧状スリットの間隔上に位置しているときは内側弧状スリットの上面から上に離れ、下向き突起が外側弧状スリットに突入したときは内側弧状スリットに突入する下向き刺片とを設け、両フレームの環状枠に半径方向外向きに突出した複数の張り出し片を設け、下フレームの上記張り出し片には、両フレームの環状枠を重合状態で回動し、両環状枠の半径方向に突出した把手が上下に重なったときに、上フレームの環状枠の上記張り出し片と、上記透過シートの周縁部の一部とを受入れ、両環状枠と、その間に透過シートを重合状態に保持する保持片を設けた。
更に、請求項２の濾過器兼篩器は、環状枠、上記環状枠から半径方向外向きに突出した把手を有する虫メガネ形の、同大の上フレーム及び下フレームと、上記上下の両フレームの重合した環状枠の間に周縁部を挟まれて支持される可撓な透過シートとからなり、上記下フレームの環状枠には円周方向に一定の間隔を保って同心状の複数の弧状スリットを設け、上フレームの環状枠の下面には上記弧状スリットと同心状で、同じ間隔を円周方向に保った複数の下向き突起と、この下向き突起と位相を異にし、且つ下向き長さが上記下向き突起よりも短く、下向き突起が上記弧状スリットの間隔上に位置しているときは弧状スリットの上面から上に離れ、下向き突起が弧状スリットに突入したときは一緒に弧状スリットに突入する下向き刺片とを設け、両フレームの環状枠に半径方向外向きに突出した複数の張り出し片を設け、下フレームの上記張り出し片には、両フレームの環状枠を重合状態で回動し、両環状枠の半径方向に突出した把手が上下に重なったときに、上フレームの環状枠の上記張り出し片と、上記透過シートの周縁部の一部とを受入れ、両環状枠と、その間に透過シートを重合状態に保持する保持片を設けたことを特徴とする。請求項１、請求項２のどちらの濾過器兼篩器も、上フレームの把手が張り出し片を兼ね、下フレームの把手が保持片を兼ねるようにしていてもよいし、上フレームの環状枠の内周と、下フレームの環状枠の内周とに回動可能に嵌合する円筒部を設けてもよい。又、下フレームの各張り出し片に下向きのストッパを設けることが好ましい。
【０００５】
【発明の実施の形態】
図１、図２は請求項１の一実施例、図３、図４は請求項２の一実施例であり、両実施例は虫メガネ形の、ほゞ同大の、例えばプラスチックで成形された上フレームＡと、下フレームＢとを有する。上フレームＡと下フレームＢは内外に回転自在に嵌合する円筒部１Ａ、１Ｂ（下フレームの円筒部１Ｂの内周に上フレームの円筒部１Ａが嵌合する。）と、上記各円筒部１Ａ、１Ｂの外周から鍔状に張り出した環状枠２Ａ、２Ｂと、各環状枠から半径方向外向きに突出した把手３Ａ、３Ｂとを有し、環状枠２Ａと２Ｂとは外径が同一であり、把手３Ａと３Ｂとは図２（Ｂ）、図４（Ｂ）で示したように上下に重なることができる。つまり、上、下のフレームＡとＢとは、環状枠２Ａ、把手３Ａと、環状枠２Ｂ、把手３Ｂとを有するのでほゞ同大の虫メガネ形なのである。
【０００６】
下フレームの環状枠２Ｂは円周方向に等間隔の複数の扇形領域ｂ、図示の実施例では中心角４５゜の８つの扇形領域ｂ…を有する。
【０００７】
又、上フレームＡは環状枠２Ａの回りから把手３Ａよりも短く半径方向外向きに突出する複数の張り出し片４Ａ…、同じく下フレームＢは環状枠２Ｂの回りから把手３Ｂよりも短く半径方向外向きに突出する複数の張り出し片４Ｂ…を有し、各張り出し片４Ｂは張り出し片３Ａを受入れて保持する逆Ｌ字形の保持片５を上面に備えている。図示の実施例では張り出し片４Ａ、張り出し片４Ｂは環状枠の回りに把手３Ａ、３Ｂに対して９０゜の位相で設けられた２つと、１８０゜の位相で設けられた合計３つからなる。尚、把手３Ａの途中には張り出し片４Ａに対応した張り出し部３Ａ′が形成してあり、把手３Ｂの途中には保持片５に対応した逆Ｌ字形の保持片３Ｂ′が設けてある。
【０００８】
又、図示の実施例は、図２（Ａ）、図４（Ａ）に示したように、把手３Ａと３Ｂとが円周方向に中心角α（約２０゜）だけ離れ、張り出し片４Ａ、張り出し部３Ａ′と保持片５、保持片３Ｂ′が上下に重ならない状態にするための目印としての矢示６Ａと６Ｂがあり、矢示６Ａは環状枠２Ａの、把手３Ａの近くに、矢示６Ｂは把手３Ｂ上に設けてある。矢示６Ａと６Ｂを一致させた図２（Ａ）、図４（Ａ）の状態で上フレームＡの環状枠２Ａを下フレームＢの環状枠２Ｂに対し反時計方向に回動して把手３Ａと３Ｂとを重ねると（図２Ｂ、図４Ｂ）、把手３Ｂ上の矢示６Ｂは把手３Ｂの上に重なった把手３Ａで隠されて見えなくなるが、環状枠２Ａの張り出し片４Ａと把手３Ａの張り出し部３Ａ′は環状枠２Ｂの張り出し片４Ｂに設けられた逆Ｌ字形の保持片５と、把手３Ｂの保持片３Ｂ′の下に潜って張り出し片４Ｂや把手３Ｂの上に重なり、上フレームＡの環状枠２Ａの下面と下フレームＢの環状枠２Ｂの上面とは強く面接触する。
【０００９】
環状枠２Ａを時計方向に回動する際、張り出し片４Ａが当初は保持片５の下に入り易くし、次いで入って潜り込むにつれ張り出し片４Ａが保持片５の下面で次第に下に押され環状枠２Ａの下面と、環状枠２Ｂの上面とが次第に強く圧接して面接触するよう、図５に示したように張り出し片４Ａの上面と保持片５の下面にカム面７Ａ、７Ｂを設け、張り出し片４Ａや張り出し部３Ａ′が完全に保持片５や保持片３Ｂ′の下に潜り込むと、張り出し片４Ａは保持片５の垂直壁部５′に当接して行き止まり、環状枠Ａを環状枠Ｂに対して反時計方向に回動することが、それ以上できないようにすることが好ましい。張り出し片４Ａや張り出し部３Ａ′を保持片５や保持片３Ｂ′の下から脱出させ、上フレームＡと下クレームＢとを分離できるようにするには環状枠Ａを時計方向に回動して各張り出し片４Ａや張り出し部３Ａ′を保持片５や保持片３Ｂ′の下から脱出させるだけでよい。
【００１０】
第１実施例と第２実施例の構成が共通している部分は以上であり、以下、両実施例の固有の構成部分と、その作用を個々に説明する。
【００１１】
請求項１の実施例では、下フレームＢの環状枠２Ｂに形成された中心角４５゜の８つの各扇形領域ｂは、内周側に該扇形領域の始端（ｂ始）から反時計方向に中心角約３８゜の弧状長スリット１１、外周側に該扇形領域の始端（ｂ始）から反時計方向に中心角約２０゜の弧状スペース１２を保って中心角約１８゜の弧状短スリット１３を有し、上記弧状長スリット１１及び弧状短スリット１３から該扇形領域の終端（ｂ終）までの間は中心角約７゜の弧状スペース１４になっている。８つの弧状長スリット１１…は同心円状に、８つの弧状短スリット１３は上記弧状長スリット１１の外側に同心円状に配置されている（図１、図２参照）。
【００１２】
又、上フレームＡの環状枠２Ａは下面の内周側に上記各弧状長スリット１１に突入可能な８本の刺片１５を内周側に等間隔（中心角４５゜の配置）で有し、外周側に上記各弧状短スリット１３に突入可能で、下向き長さが上記刺片１５よりも少し長い８本の突起１６を、同様に円周方向に等間隔ではあるが、位相を４５゜／２違わせて有する。即ち、刺片１５（突起１６）の円周方向の間隔の真中（中心角４５゜／２の位置）に外周と内周との違いはあるが、突起１６（刺片１５）が配列されている。
【００１３】
そして、隣接した扇形領域では、１つの扇形領域の反時計方向の終端（ｂ終）が反時計方向に隣接した他の扇形領域の始端（ｂ始）を兼ね、時計方向の始端（ｂ始）が時計方向に隣接した他の扇形領域の終端（ｂ終）を兼ねる。
【００１４】
上フレームと下フレームの円筒部１Ａ、１Ｂを回動可能に嵌合し、把手３Ａ、３Ｂの矢示６Ａ、６Ｂを一致させると、各刺片１５は内周側の弧状長スリット１１の途中上に位置し、各突起１６は外周側の弧状スペース１４の終端部上に位置する（図２Ａ）。この場合、突起１６の下向き長さが刺片よりも長いので、突起１６の下端は弧状スペース１４の終端部に接触するが、刺片１５の下端は弧状長スリット１１の上面から上に離れる（図２Ａ′）。
【００１５】
上記、図２（Ａ、Ａ′）の状態から、段落０００８、０００９で述べたように把手３Ａを持ち、上フレームＡの環状枠２Ａを下フレームＢの環状枠２Ｂ上で反時計方向に回動し、矢示６Ａを下フレームの矢示６Ｂに一致させると、図２（Ｂ、Ｂ′）に示したように各突起１６は弧状短スリット１３内に落ち込んで上フレームＡの環状枠２Ａの下面と、下フレームＢの環状枠２Ｂ上面とは、張り出し片４Ａなどと保持片５などの作用で強く面接触し、これに伴い各刺片１５も弧状長スリット１１内に落ち込む。
【００１６】
濾過器として使用するには、メッシュ１００〜２００程度で、大きさは環状枠２Ａ、２Ｂの直径よりも大きい円形、又は環状枠の直径よりも長い長さを一辺とする正方形の濾布を使用し、篩器として使用するには濾布よりもメッシュが大で、同様な大きさの円形や、正方形の可撓な篩用布や金網の篩シートを使用する。濾布と、篩シートを総称して可撓な透過シートＣと記す。
【００１７】
濾布である透過シートＣを使用し、濾過器として使用するには、上フレームＡと下フレームＢとを分解し、下フレームＢ上に濾布の透過シートＣを載せ、その上に矢示６Ａを矢印６Ｂに一致させて上フレームＡを重ねて図２（Ａ、Ａ′）の状態にする。この状態では段落００１４で述べたように各刺片１５の下端は弧状長スリット１１の上面から上に離れ、各突起１６の下端は弧状スペース１４の終端部上に濾布を介して接触する。
【００１８】
この状態で濾布（透過シートＣ）の中心部を指で下に押すなどして弛ませ、濾布を茶漉し状の下向きに膨らんだ袋Ｃ′に形成する。この際、透過シートＣの周縁部は下フレームの弧状スペース１４の終端部上に接触しようとする各突起１６の下で半径方向内向きにずれ動く。
【００１９】
濾布シートの上記半径方向内向きのずれ動きを容易にするため、各突起１６の下端は図示のように半球面にしておくことが好ましい。
【００２０】
こうして濾布に下向きに膨らんだ茶漉し状の袋Ｃ′が形成できたら、上下両フレームＡ、Ｂを回動して把手６Ａと６Ｂを上下に重ね、図２（Ｂ）の状態にする。これにより各刺片１５は濾布の周縁部を刺して弧状長スリット１１中に落ち込み、各突起１６は弧状短スリット１３に落ち込んで濾布の周縁部を弧状短スリット１３中に上から押し込み、環状枠２Ａの下面は、張り出し片４Ａなどと保持片５などとのカム作用で濾布の周縁部を強く挟んで環状枠２Ｂの上に強く面接触し、茶漉し状の袋部Ｃ′が形成された透過シートＣの周縁部を不動に保持し、図６に示した濾過器になる。
【００２１】
このとき濾布の周縁部は、図５（Ｂ、Ｃ）に示したように、保持片５の下に潜り込もうとする張り出し片４Ａによって一緒に保持片５の下に押し込まれ、且つ濾布の終縁部を刺して弧状長スリット中に落ち込む刺片１５や、濾布の周縁部を下に押して弧状短スリット中に押し込む突起１６の作用で濾布は環状枠２Ａ、２Ｂに挟まれながら円周方向に移動するが、茶漉し状の袋部Ｃ′はその形態を維持する。
【００２２】
従って、図７に示すように上下に重なった上下のフレームの環状枠や、半径方向外向きに突出する張り出し片４Ｂと上下に重なった把手３Ａ、３Ｂを塗料容器の縁の上に載せ、下向きに膨らんだ濾布の袋部Ｃ′のなかに塗料を入れることにより袋部Ｃ′の全面から濾過された塗料が容器内に流れ落ち、滴下する。このようにして、濾布の広い面積を使用して塗料を迅速に濾過できる。この場合、上下のフレームの把手３Ａ、３Ｂは上下に重なって一体になっているので塗料容器の上に載せたり、容器の上から外したりする取扱いが容易に行える。
【００２３】
濾過が終わったら両フレームの把手３Ａ、３Ｂで操作して上下のフレームを逆方向に回動して張り出し片４Ａを保持片５の下から脱出させたのち上フレームＡを下フレームＢから上に離して分解し、塗料を濾過した濾布Ｃを外して廃棄し、両フレームＡ、Ｂに塗料が付着して汚れていたら溶剤などで洗って汚れを除去し、再使用する。
【００２４】
篩器として使用する場合は篩用布や金網などの篩シートになる透過シートＣを下フレームＢ上に載せ、その上に段落００１７で述べたように上フレームＡを重ねる。そして、濾過シートを弛ませて茶漉し状の袋Ｃ′を形成する必要がないから、透過シートの周縁部を外方に引張って突起１６の下でずれ動かし、篩用の透過シートＣを上下の両環状枠の内周の内部で緊張させ、それから把手３Ａ、３Ｂが上下に重なるように環状枠２Ａ、２Ｂを回動し、図２（Ｂ、Ｂ′）の状態にして篩用の透過シートを段落００２０で述べたように不動に保持する。
【００２５】
従って、上下に重なった環状枠や張り出し片を容器の縁の上に載せ、緊張している篩シートの上に物を供給したり、擦り付けたりし、篩シートの布目や網目を通ったものを容器のなかに集めることができ、この場合も、上下に重なった両フレームの把手３Ａ、３Ｂは一体になっているので容器の上に載せたり、容器の上から外したりする取扱いが容易に行える。
【００２６】
篩い作業が終わったら両フレームの把手３Ａ、３Ｂで操作して、上のフレームの環状枠２Ａを下のフレームの環状枠２Ｂの上から外して両フレームを分解し、篩シートを外して織目や網目に詰まった物を、洗うなどして除去し、再使用する。
【００２７】
請求項２の実施例では、下フレームＢの環状枠２Ｂに形成された中心角４５゜の８つの各扇形領域ｂは、該扇形領域の始端（ｂ始）から反時計方向に中心角約３８゜の弧状スリット２１、上記弧状スリット２１から該扇形領域の終端（ｂ終）までの間は中心角約７゜の弧状スペース２２になっている（図３、４参照）。
【００２８】
又、上フレームＡの環状枠２Ａは下面の内周側に上記各弧状スリット２１に突入可能な８本の刺片２３を等間隔（中心角４５゜の配置）で有すると共に、上記各弧状スリット２１に突入可能で、下向き長さが上記刺片２３よりも少し長い８本の突起２４を、同様に円周方向に等間隔ではあるが、位相を４５゜／２違わせて有する。即ち、刺片２３（突起２４）の円周方向の間隔の真中（中心角４５゜／２の位置）に突起２４（刺片２３）が配列されている。
【００２９】
そして、隣接した扇形領域では、１つの扇形領域の反時計方向の終端（ｂ終）が反時計方向に隣接した他の扇形領域の始端（ｂ始）を兼ね、時計方向の始端（ｂ始）が時計方向に隣接した他の扇形領域の終端（ｂ終）を兼ねる。
【００３０】
上フレームと下フレームの円筒部１Ａ、１Ｂを回動可能に嵌合し、把手３Ａ、３Ｂの矢示６Ａ、６Ｂを一致させると、各刺片２３は弧状スリット２１の途中上に位置し、各突起２４は弧状スペース２２上に位置する（図４Ａ）。この場合、突起２４の下向き長さが刺片よりも長いので、突起２４の下端は弧状スペース２２に接触するが、刺片２３の下端は弧状スリット２１の上面から上に離れる（図４Ａ′）。
【００３１】
上記、図４（Ａ、Ａ′）の状態から、段落０００８、０００９で述べたように把手３Ａを持ち、上フレームＡの環状枠２Ａを下フレームＢの環状枠２Ｂ上で反時計方向に回動し、矢示６Ａを下フレームの矢示６Ｂに一致させると、図４（Ｂ、Ｂ′）に示したように各突起２４は弧状スリット２１内に落ち込んで上フレームＡの環状枠２Ａの下面と、下フレームＢの環状枠２Ｂ上面とは、張り出し片４Ａなどと保持片５などの作用で強く面接触し、これに伴い各刺片２３も弧状スリット２１内に落ち込む。
【００３２】
濾過器として使用するには、メッシュ１００〜２００程度で、大きさは環状枠２Ａ、２Ｂの直径よりも大きい円形、又は環状枠の直径よりも長い長さを一辺とする正方形の濾布を使用し、篩器として使用するには濾布よりもメッシュが大で、同様な大きさの円形や、正方形の可撓な篩用布や金網の篩シートを使用する。濾布と、篩シートを総称して可撓な透過シートＣと記す。
【００３３】
濾布である透過シートＣを使用し、濾過器として使用するには、上フレームＡと下フレームＢとを分解し、下フレームＢ上に濾布の透過シートＣを載せ、その上に矢示６Ａを矢印６Ｂに一致させて上フレームＡを重ねて図４（Ａ、Ａ′）の状態にする。この状態では段落００１４で述べたように各刺片２３の下端は弧状スリット２１の上面から上に離れ、各突起２４の下端は弧状スペース２２の上に濾布を介して接触する。
【００３４】
この状態で濾布（透過シートＣ）の中心部を指で下に押すなどして弛ませ、濾布を茶漉し状の下向きに膨らんだ袋Ｃ′に形成する。この際、透過シートＣの周縁部は下フレームの弧状スペース２２の終端部上に接触しようとする各突起２４の下で半径方向内向きにずれ動く。
【００３５】
濾布シートの上記半径方向内向きのずれ動きを容易にするため、各突起２４の下端は図示のように半球面にしておくことが好ましい。
【００３６】
こうして濾布に下向きに膨らんだ茶漉し状の袋Ｃ′が形成できたら、上下両フレームＡ、Ｂを回動して把手６Ａと６Ｂを上下に重ね、図４（Ｂ）の状態にする。これにより各刺片２３は濾布の周縁部を刺して弧状スリット２１中に落ち込み、各突起２４は弧状スリット２１に落ち込んで濾布の周縁部を弧状スリット２１中に上から押し込み、環状枠２Ａの下面は、張り出し片４Ａなどと保持片５などとのカム作用で濾布の周縁部を強く挟んで環状枠２Ｂの上に強く面接触し、茶漉し状の袋部Ｃ′が形成された透過シートＣの周縁部を不動に保持し、図６に示した濾過器になる。
【００３７】
このとき濾布の周縁部は、図５（Ｂ、Ｃ）に示したように、保持片５の下に潜り込もうとする張り出し片４Ａによって一緒に保持片５の下に押し込まれ、且つ濾布の終縁部を刺して弧状スリット２１中に落ち込む刺片２３や、濾布の周縁部を下に押して弧状スリット２１中に押し込む突起２４の作用で濾布は環状枠２Ａ、２Ｂに挟まれながら円周方向に移動するが、茶漉し状の袋部Ｃ′はその形態を維持する。
【００３８】
従って、図７に示すように上下に重なった上下のフレームの環状枠や、半径方向外向きに突出する張り出し片４Ｂと上下に重なった把手３Ａ、３Ｂを塗料容器の縁の上に載せ、下向きに膨らんだ濾布の袋部Ｃ′のなかに塗料を入れることにより袋部Ｃ′の全面から濾過された塗料が容器内に流れ落ち、滴下する。このようにして、濾布の広い面積を使用して塗料を迅速に濾過できる。この場合、上下のフレームの把手３Ａ、３Ｂは上下に重なって一体になっているので塗料容器の上に載せたり、容器の上から外したりする取扱いが容易に行える。
【００３９】
濾過が終わったら両フレームの把手３Ａ、３Ｂで操作して上下のフレームを逆方向に回動して張り出し片４Ａを保持片５の下から脱出させたのち上フレームＡを下フレームＢから上に離して分解し、塗料を濾過した濾布Ｃを外して廃棄し、両フレームＡ、Ｂに塗料が付着して汚れていたら溶剤などで洗って汚れを除去し、再使用する。
【００４０】
篩器として使用する場合は篩用布や金網などの篩シートになる透過シートＣを下フレームＢ上に載せ、その上に段落００１７で述べたように上フレームＡを重ねる。そして、濾過シートを弛ませて茶漉し状の袋Ｃ′を形成する必要がないから、透過シートの周縁部を外方に引張って突起２４の下でずれ動かし、篩用の透過シートＣを上下の両環状枠の内周の内部で緊張させ、それから把手３Ａ、３Ｂが上下に重なるように環状枠２Ａ、２Ｂを回動し、図４（Ｂ、Ｂ′）の状態にして篩用の透過シートを段落００２０で述べたように不動に保持する。
【００４１】
従って、上下に重なった環状枠や張り出し片を容器の縁の上に載せ、緊張している篩シートの上に物を供給したり、擦り付けたりし、篩シートの布目や網目を通ったものを容器のなかに集めることができ、この場合も、上下に重なった両フレームの把手３Ａ、３Ｂは一体になっているので容器の上に載せたり、容器の上から外したりする取扱いが容易に行える。
【００４２】
篩い作業が終わったら両フレームの把手３Ａ、３Ｂで操作して、上フレームＡの環状枠２Ａを下フレームＢの環状枠２Ｂの上から外して両フレームＡ、Ｂを分解し、篩シートを外して織目や網目に詰まった物を、洗うなどして除去し、再使用する。
【００４３】
そして、下フレームＢの各張り出し片４Ｂには該フレームの中心から等しい距離を保ってストッパ８を設けておく。
【００４４】
【発明の効果】
請求項１、請求項２により濾過用の透過シートを使い捨てするだけでよい濾過器兼用の篩器が得られる。そして、下フレームの円筒部の内周に上フレームの円筒部を嵌合することによって、回転可能に組立てることで、組立て状態で上フレームと下フレームが分解することはない。又、下フレームの各張り出し片に中心から等しい距離を保ってストッパを設けておくことにより、濾過するため、或いは篩いとして使用するために容器の上に載せたとき、ストッパが容器の縁に当接するので容器の上からずれ落ちることが防げる。請求項１では、下フレームの環状枠の外周側と内周側に外側弧状スリットと内側弧状スリットとを同心状に内外二重に設ける必要があるが、請求項２では弧状スリットを一重に設けるだけでよいため、請求項１に較べて請求項２は外径の小さな濾過器兼篩器を提供できる。

BACKGROUND OF THE INVENTION
  The present invention relates to a filter and sieve that can be used both as a filter and as a sieve.
[0002]
[Prior art]
  The painting spray gun comes with a cup that supplies paint to the gun, but even if the cup has a large capacity, it is only about one stand, so if you want to paint in large quantities, refill the cup many times. Therefore, it takes time for replenishment and the work efficiency of painting is reduced. For this purpose, it is a hopper type with a bucket-type handle and has a capacity of about 4 and one end of the flexible tube is connected to the liquid supply port on the bottom with an open / close cock, and the attached cup is removed from the spray gun for painting. The other end of the tube is connected to a gun cup attachment port, and a so-called polytank is used to supply paint to the gun by hanging the hook by hanging it on an appropriate hook. In either case, if a foreign substance is contained in the paint, the foreign substance enters the spray gun, clogs the nozzle of the spray gun, and the paint cannot be sprayed. This tendency often occurs when the paint left over the day before is reused. If this happens, the painting operation must be interrupted, the spray gun must be disassembled, and the foreign matter clogged in the nozzle must be removed, which is very laborious and dirty.
[0003]
[Problems to be solved by the invention]
  Therefore, a disposable filter in which a small-diameter opening of a megaphone-shaped paper conical cylinder corresponding to the size of the container, such as a spray gun cup or the above-mentioned plastic tank, is covered with a filter cloth (mesh of about 100 to 200). Is commercially available, it is used to filter the paint that goes into the spray gun cup or plastic tank. This filter is relatively expensive because it takes a lot of time to attach a filter cloth to a small-diameter opening of a megaphone-shaped paper conical cylinder and close it, and throwing away only once is contrary to resource saving. . Further, since the filtration area depends on the opening area of the small-diameter opening of the megaphone-shaped conical cylinder, it takes a very long time to finish filtering the entire amount of the paint put into the conical cylinder from the large-diameter part.

[0010]
  The portions in which the configurations of the first embodiment and the second embodiment are in common are as described above, and hereinafter, the unique components of both embodiments and their functions will be described individually.
[0011]
  In the embodiment of claim 1, each of the eight sector regions b having a central angle of 45 ° formed on the annular frame 2B of the lower frame B is counterclockwise from the start end (b start) of the sector region to the inner peripheral side. An arc-shaped long slit 11 having a central angle of about 38 °, and an arc-shaped short slit 13 having a central angle of about 18 ° while maintaining an arc-shaped space 12 having a central angle of about 20 ° in the counterclockwise direction from the start end (b-start) of the fan-shaped region on the outer peripheral side. The arc-shaped space 14 having a central angle of about 7 ° is formed between the arc-shaped long slit 11 and the arc-shaped short slit 13 and the end (b-end) of the fan-shaped region. The eight arc-shaped long slits 11 are concentric, and the eight arc-shaped short slits 13 are the arc-shaped long slits.11ofOutsideIt is arranged concentrically on the side (see FIGS. 1 and 2).
[0012]
  Further, the annular frame 2A of the upper frame A has eight stabs 15 that can enter the arc-shaped long slits 11 on the inner peripheral side of the lower surface at equal intervals (disposed at a central angle of 45 °) on the inner peripheral side. The eight protrusions 16 that can enter the arc-shaped short slits 13 on the outer peripheral side and have a downward length slightly longer than the stab piece 15 are also equally spaced in the circumferential direction, but the phase is 45 °. / Have two different. That is, there is a difference between the outer circumference and the inner circumference in the middle of the circumferential interval of the stab 15 (projection 16) (position of the central angle 45 ° / 2), but the projection 16 (stab 15) is arranged. Yes.
[0013]
  In the adjacent sector area, the counterclockwise end (b end) of one sector area also serves as the start end (b start) of another sector area adjacent in the counterclockwise direction, and the clockwise start end (b start). Also serves as the end (b end) of another fan-shaped region adjacent in the clockwise direction.
[0014]
  When the cylindrical portions 1A and 1B of the upper frame and the lower frame are fitted so as to be rotatable and the arrows 6A and 6B of the handles 3A and 3B are made to coincide with each other, each stab 15 is in the middle of the arc-shaped long slit 11 on the inner peripheral side. Located above, each protrusion 16 is located on the terminal end of the arcuate space 14 on the outer peripheral side (FIG. 2A). In this case, since the downward length of the protrusion 16 is longer than that of the stab, the lower end of the protrusion 16 contacts the terminal portion of the arc-shaped space 14, but the lower end of the stab 15 is separated upward from the upper surface of the arc-shaped long slit 11 ( FIG. 2A ′).
[0015]
  2 (A, A ′), hold the handle 3A as described in paragraphs 0008 and 0009, and rotate the annular frame 2A of the upper frame A counterclockwise on the annular frame 2B of the lower frame B. When the arrow 6A moves to coincide with the arrow 6B of the lower frame, each projection 16 falls into the arc-shaped short slit 13 as shown in FIG. 2 (B, B ′), and the annular frame 2A of the upper frame A The lower surface of the lower frame B and the upper surface of the annular frame 2B of the lower frame B are a protruding piece 4A and a holding piece5As a result, the stabs 15 also fall into the arc-shaped long slits 11.
[0016]
  In order to use as a filter, a mesh filter of about 100 to 200 is used, and the size of the filter cloth is a circle larger than the diameter of the annular frames 2A and 2B, or a square filter cloth having a longer side than the diameter of the annular frame. However, in order to use as a sieve, the mesh is larger than the filter cloth, and a circular or square flexible sieve cloth or a wire mesh sieve sheet having the same size is used. The filter cloth and the sieve sheet are collectively referred to as a flexible transmission sheet C.
[0017]
  In order to use the filter cloth as the permeation sheet C and use it as a filter, the upper frame A and the lower frame B are disassembled, the filter cloth permeation sheet C is placed on the lower frame B, and an arrow is shown above it 6A is made to coincide with the arrow 6B, and the upper frame A is overlapped to be in the state of FIG. 2 (A, A ′). In this state, as described in paragraph 0014, the lower end of each stab piece 15 is separated from the upper surface of the arc-shaped long slit 11, and the lower end of each projection 16 is in contact with the end portion of the arc-shaped space 14 via a filter cloth.
[0018]
  In this state, the center portion of the filter cloth (transmission sheet C) is loosened by pushing it down with a finger or the like, and the filter cloth is formed into a bag C ′ swelled downward like a teacup. At this time, the peripheral edge portion of the transmission sheet C shifts inward in the radial direction under the protrusions 16 that are to contact the terminal portion of the arcuate space 14 of the lower frame.
[0019]
  In order to facilitate the radial inward movement of the filter cloth sheet, the lower end of each protrusion 16 is preferably a hemispherical surface as shown.
[0020]
  When the teacup-shaped bag C 'swelled downward is formed on the filter cloth in this way, the upper and lower frames A and B are rotated so that the grips 6A and 6B are stacked vertically to obtain the state shown in FIG. Thereby, each stab 15 pierces the peripheral edge of the filter cloth and falls into the arc-shaped long slit 11, and each projection 16 falls into the arc-shaped short slit 13 to push the peripheral edge of the filter cloth into the arc-shaped short slit 13 from above. The lower surface of the annular frame 2A is a protruding piece4AEtc. and holding pieces5With the cam action and the like, the peripheral edge of the filter cloth is strongly sandwiched and the surface is strongly in contact with the annular frame 2B, and the peripheral edge of the transmission sheet C on which the teacup-shaped bag C 'is formed is held stationary. The filter shown in FIG. 6 is obtained.
[0021]
  At this time, the peripheral portion of the filter cloth is as shown in FIG.Holding pieceTogether by overhanging piece 4A trying to dive under 5Holding piece 5The filter cloth is pushed by the action of the stab 15 that is pushed down and stabs into the arc-shaped long slit by piercing the end edge of the filter cloth and the protrusion 16 that pushes the peripheral edge of the filter cloth and pushes it into the arc-shaped short slit. While moving in the circumferential direction while being sandwiched between the annular frames 2A and 2B, the teacup-shaped bag portion C 'maintains its form.
[0022]
  Therefore, as shown in FIG. 7, the upper and lower frames of the upper and lower frames are annularly protruded and protrude outward in the radial direction.OverhangPaint that has been filtered from the entire surface of the bag portion C ′ by placing the handles 3A and 3B overlapping the top and bottom of 4B on the edge of the paint container and placing the paint in the bag portion C ′ of the filter cloth that bulges downward. Flows down into the container and drops. In this way, the paint can be quickly filtered using a large area of the filter cloth. In this case, the handles 3A and 3B of the upper and lower frames are integrated with each other in the vertical direction, so that handling such as placing on or removing from the paint container can be easily performed.
[0023]
  When filtration is finished, operate the handles 3A and 3B of both frames to rotate the upper and lower frames in the opposite direction, and remove the protruding piece 4A.Holding piece5 After escaping from the bottom, disassemble the upper frame A away from the lower frame B, remove the filter cloth C from which the paint has been filtered, and dispose of it. Wash with solvent to remove dirt and reuse.
[0024]
  When used as a sieve, a permeable sheet C to be a sieve sheet such as a sieving cloth or a wire mesh is placed on the lower frame B, and the upper frame A is overlaid thereon as described in paragraph 0017. Then, since it is not necessary to loosen the filter sheet to form a teacup-shaped bag C ′, the perimeter of the permeable sheet is pulled outward and moved under the projection 16 to move the permeable sheet C for sieving up and down. 2A and 2B are rotated so that the handles 3A and 3B overlap vertically, and the state shown in FIG. 2 (B and B ′) is obtained. Hold the sheet stationary as described in paragraph 0020.
[0025]
  Therefore, an annular frame or overhanging piece that overlaps the top and bottom is placed on the edge of the container, and the object is fed or rubbed onto the strained sieve sheet, and the sieve sheet that passes through the mesh or mesh In this case, the handles 3A and 3B of the two frames that overlap each other are integrated so that they can be easily mounted on the container or removed from the container. .
[0026]
  After the sieving operation is finished, operate the handles 3A and 3B of both frames, remove the upper frame annular frame 2A from the upper frame annular frame 2B, disassemble both frames, remove the sieve sheet, and weave Remove the clogged material and the mesh and reuse it.
[0027]
  In the embodiment of claim 2, each of the eight sector regions b having a central angle of 45 ° formed in the annular frame 2B of the lower frame B has a central angle of about 38 in the counterclockwise direction from the start end (b start) of the sector region. An arc-shaped slit 21 having a central angle of about 7 ° is formed between the arc-shaped slit 21 and the arc-shaped slit 21 to the end (b-end) of the fan-shaped region (see FIGS. 3 and 4).
[0028]
  Further, the annular frame 2A of the upper frame A has eight stabs 23 that can be inserted into the arc-shaped slits 21 on the inner peripheral side of the lower surface at equal intervals (disposed at a central angle of 45 °). Eight protrusions 24 that can enter the nozzle 21 and have a downward length slightly longer than the stab piece 23 are also equally spaced in the circumferential direction but have a phase difference of 45 ° / 2. That is, the protrusion 24 (the stab 23) is arranged in the middle of the interval in the circumferential direction of the stab 23 (the protrusion 24) (at a central angle of 45 ° / 2).
[0029]
  In the adjacent sector area, the counterclockwise end (b end) of one sector area also serves as the start end (b start) of another sector area adjacent in the counterclockwise direction, and the clockwise start end (b start). Also serves as the end (b end) of another fan-shaped region adjacent in the clockwise direction.
[0030]
  When the cylindrical portions 1A and 1B of the upper frame and the lower frame are fitted so as to be rotatable and the arrows 6A and 6B of the grips 3A and 3B are made to coincide with each other, each stab 23 is positioned on the middle of the arc-shaped slit 21. Each protrusion 24 is located on the arcuate space 22 (FIG. 4A). In this case, since the downward length of the protrusion 24 is longer than that of the stab, the lower end of the protrusion 24 contacts the arcuate space 22, but the lower end of the stab 23 is separated upward from the upper surface of the arcuate slit 21 (FIG. 4A '). .
[0031]
  From the state of FIG. 4 (A, A ′), hold the handle 3A as described in paragraphs 0008 and 0009 and rotate the annular frame 2A of the upper frame A counterclockwise on the annular frame 2B of the lower frame B. When the arrow 6A is moved to coincide with the arrow 6B of the lower frame, each protrusion 24 falls into the arc-shaped slit 21 as shown in FIG. 4 (B, B '), and the annular frame 2A of the upper frame A The lower surface and the upper surface of the annular frame 2B of the lower frame B are the overhanging piece 4A and the holding piece.5As a result, the stabs 23 fall into the arc-shaped slits 21 as well.
[0032]
  In order to use as a filter, a mesh filter of about 100 to 200 is used, and the size of the filter cloth is a circle larger than the diameter of the annular frames 2A and 2B, or a square filter cloth having a longer side than the diameter of the annular frame. However, in order to use as a sieve, the mesh is larger than the filter cloth, and a circular or square flexible sieve cloth or a wire mesh sieve sheet having the same size is used. The filter cloth and the sieve sheet are collectively referred to as a flexible transmission sheet C.
[0033]
  In order to use the filter cloth as the permeation sheet C and use it as a filter, the upper frame A and the lower frame B are disassembled, the filter cloth permeation sheet C is placed on the lower frame B, and an arrow is shown above it. 6A is made to coincide with the arrow 6B, and the upper frame A is overlapped to be in the state of FIG. 4 (A, A ′). In this state, as described in paragraph 0014, the lower end of each stab 23 is separated from the upper surface of the arc-shaped slit 21, and the lower end of each projection 24 is in contact with the arc-shaped space 22 via the filter cloth.
[0034]
  In this state, the center portion of the filter cloth (transmission sheet C) is loosened by pushing it down with a finger or the like, and the filter cloth is formed into a bag C ′ swelled downward like a teacup. At this time, the peripheral edge portion of the transmission sheet C shifts inward in the radial direction under each protrusion 24 that is to contact the terminal portion of the arcuate space 22 of the lower frame.
[0035]
  In order to facilitate the inward radial movement of the filter cloth sheet, it is preferable that the lower end of each protrusion 24 be a hemispherical surface as shown in the figure.
[0036]
  When the teacup-shaped bag C ′ swelled downward is formed on the filter cloth in this way, the upper and lower frames A and B are rotated so that the grips 6A and 6B are vertically stacked to obtain the state shown in FIG. As a result, each stab 23 stabs the peripheral edge of the filter cloth and falls into the arc-shaped slit 21, and each projection 24 falls into the arc-shaped slit 21 to depress the peripheral edge of the filter cloth.Arc slit21 is pushed from above into the lower surface of the annular frame 2A4AEtc. and holding pieces5With the cam action and the like, the peripheral edge of the filter cloth is strongly sandwiched and the surface is strongly in contact with the annular frame 2B, and the peripheral edge of the transmission sheet C on which the teacup-shaped bag C 'is formed is held stationary. The filter shown in FIG. 6 is obtained.
[0037]
  At this time, the peripheral portion of the filter cloth is as shown in FIG.Holding pieceTogether by overhanging piece 4A trying to dive under 5Holding piece 5And pushed into the end of the filter cloth.Arc slitThe stab 23 falling into the 21 and the peripheral edge of the filter cloth are pushed downward to form an arc-shaped slit.21Projection to be pushed in24As a result, the filter cloth moves in the circumferential direction while being sandwiched between the annular frames 2A and 2B, but the teacup-shaped bag portion C 'maintains its form.
[0038]
  Therefore, as shown in FIG. 7, the upper and lower frames of the upper and lower frames are annularly protruded and protrude outward in the radial direction.OverhangPaint that has been filtered from the entire surface of the bag portion C ′ by placing the handles 3A and 3B overlapping the top and bottom of 4B on the edge of the paint container and placing the paint in the bag portion C ′ of the filter cloth that bulges downward. Flows down into the container and drops. In this way, the paint can be quickly filtered using a large area of the filter cloth. In this case, the handles 3A and 3B of the upper and lower frames are integrated with each other in the vertical direction, so that handling such as placing on or removing from the paint container can be easily performed.
[0039]
  When filtration is finished, operate the handles 3A and 3B of both frames to rotate the upper and lower frames in the opposite direction, and remove the protruding piece 4A.Holding piece5 After escaping from the bottom, disassemble the upper frame A away from the lower frame B, remove the filter cloth C from which the paint has been filtered, and dispose of it. Wash with solvent to remove dirt and reuse.
[0040]
  When used as a sieve, a permeable sheet C to be a sieve sheet such as a sieving cloth or a wire mesh is placed on the lower frame B, and the upper frame A is overlaid thereon as described in paragraph 0017. Then, since it is not necessary to loosen the filter sheet to form a tea strainer-like bag C ′, the perimeter of the permeable sheet is pulled outward and shifted under the projection 24 to move the permeable sheet C for sieving up and down. 4B, the annular frames 2A and 2B are rotated so that the handles 3A and 3B overlap vertically, and the state shown in FIG. 4 (B and B ') is obtained. Hold the sheet stationary as described in paragraph 0020.
[0041]
  Therefore, an annular frame or overhanging piece that overlaps the top and bottom is placed on the edge of the container, and the object is fed or rubbed onto the strained sieve sheet, and the sieve sheet that passes through the mesh or mesh In this case, the handles 3A and 3B of the two frames that overlap each other are integrated so that they can be easily mounted on the container or removed from the container. .
[0042]
  When the sieving operation is finished, operate the grips 3A and 3B of both frames to remove the annular frame 2A of the upper frame A.Lower frame BBoth frames removed from the top of the annular frame 2BA, BIs removed, the sieve sheet is removed, and the material clogged with the weave or mesh is removed by washing and reused.

  And lower frameBEach overhang of4BThe stopper 8 is provided at an equal distance from the center of the frame.
[0044]
【The invention's effect】
  According to the first and second aspects, a filter and sieve device that only needs to be disposable can be obtained. Then, by fitting the cylindrical portion of the upper frame to the inner periphery of the cylindrical portion of the lower frame, the upper frame and the lower frame are not disassembled in the assembled state. In addition, by placing a stopper on each overhanging piece of the lower frame at an equal distance from the center, when the stopper is placed on the container for filtration or use as a sieve, the stopper touches the edge of the container. Since it comes in contact, it can be prevented from slipping off the top of the container. In the first aspect, it is necessary to provide the outer arc-shaped slit and the inner arc-shaped slit concentrically on the outer peripheral side and the inner peripheral side of the annular frame of the lower frame, but in claim 2, the arc-shaped slit is provided in a single layer. Therefore, as compared with claim 1, claim 2 can provide a filter and sieve having a smaller outer diameter.
