Description

【０００１】
【発明の属する技術分野】
本発明は、ロール式遮蔽装置及び開口部装置に係り、特に操作性の向上を図ったロール式遮蔽装置及び開口部装置に関する。
【０００２】
開口部装置としては、建物の開口に設けられる枠体と、この枠体内に開閉自在に設けられた障子と、前記枠体に設けられるロール式網戸とを備えたものが知られている（例えば、実公昭５２−１５０８９号公報参照）。前記ロール式網戸は、網体を巻取って収納する収納部と、網体の先端部を保持し網体を収納部から引き出し入れして網戸の開閉を行う可動框と、この可動框の両端部を摺動自在に案内する案内部とを有している。
【０００３】
前記ロール式網戸においては、網体が収納部に自動的に巻取収納されるようにバネで付勢されているため、可動框を網戸閉方向に移動して手を離すとバネの力で可動框が収納部方向へ移動してしまう。そこで、全開・全閉状態でしか使用しないタイプのロール式網戸の場合、網戸全閉時に戸先框が枠にラッチ部品等で係止されるようなっていることが多い。一方、引違い窓等に横引きタイプのロール網戸を使用する場合のように網戸の可動框を任意の位置で停止させる必要のある場合には、例えば枠に対してゴム等の制動部材を押しつけて可動框を停止させるようした停止機構が採用されている。この停止機構の操作部は、一般的に可動框の長手方向略中間部に設けられている。

【発明が解決しようとする課題】
しかしながら、前記ロール式網戸ないし該ロール式網戸を備えた開口部装置においては、停止機構の操作部が可動框の長手方向略中間部に設けられているため、例えば子供などでは操作摘み部に手が届きにくい場合があり、操作性に劣る問題があった。
【０００６】
本発明は、前記事情を考慮してなされたもので、可動框の長手方向の何れの位置でも操作部を操作することができ、操作性に優れたロール式遮蔽装置及び開口部装置を提供することにある。

【００１１】
【発明の実施の形態】
以下に、本発明の実施の形態を添付図面に基いて詳述する。図１は本発明の実施の形態を示す開口部戸の縦断面図、図２は同開口部装置の横断面図、図３は網体を概略的に示す図で、（ａ）は正面図、（ｂ）は（ａ）のＡ−Ａ線断面図、（ｃ）は（ａ）のＢ−Ｂ線断面図、図４は可動框の一端を概略的に示す斜視図、図５はロール式網戸の使用状態を示す横断面図である。
【００１２】
図１、図２ないし図５に示すように、開口部装置１は、建物の開口に設けられるサッシ枠である枠体２と、この枠体２内に開閉自在に設けられた障子３ａ，３ｂと、前記枠体２に設けられるロール式遮蔽装置であるロール式網戸６とを備えている。前記枠体２は、例えばアルミ押出形材からなる上枠２ａ、下枠２ｂ及び左右の縦枠２ｃ，２ｄからなっている。図示例の開口部装置１は引違い窓サッシとして構成されており、枠体２内に内外の障子３ａ，３ｂが横方向に引違い状に開閉自在に設けられている。障子３ａ，３ｂは、例えばアルミ押出形材からなる上框４ａ、下框４ｂ及び左右の縦框４ｃ，４ｄからなる框体４内にガラスパネル５を装着してなる。
【００１３】
前記ロール式網戸６は、巻取可能な遮蔽材である網体７と、この網体７を巻取って収納する収納部８と、その網体７の先端部を保持し網体７を収納部８から引き出し入れして網戸６の開閉を行う可動框（戸先框ともいう）９と、この可動框９の両端部を摺動自在に案内する案内部１０，１０と、それぞれの案内部１０に設けられたラック１１と、それぞれのラック１１に噛合するピニオン１２と、前記可動框９に沿って回転自在に支持され前記両ピニオン１２，１２を連結する連動軸１３と、前記可動框９を任意の位置に停止させる停止機構１４とを備えている。前記収納部８内には網体７を巻取る巻取部である巻取軸１５が回転自在に設けられ、この巻取軸１５が網体７を巻取る方向に付勢手段である図示しないバネにより付勢されている。
【００１４】
図示例の開口部装置１は枠体２の左右にロール式網戸６，６を備えている。左側のロール式網戸６は図５に示すように開状態にある外障子３ｂの戸先框４ｄの室内面に取付けた戸先補助框１６との間を網体７で覆うようになっており、右側のロール式網戸６は開状態の内障子３ａの戸先框４ｄとの間を網体７で覆うようになっている。左側のロール式網戸６の可動框９には外障子３ｂの戸先補助框１６との間を塞いで虫の侵入を防止するヒレ状の第１の虫除け部材１７ａ及び上枠２ａ、下枠２ｂとの間を塞いで虫の侵入を防止するヒレ状の第２の虫除け部材１７ｂが設けられている。右側のロール式網戸６の可動框９には内障子３ａの戸先框４ｄとの間を塞いで虫の侵入を防止するヒレ状の第１の虫除け部材１７ａ及び上枠２ａ、下枠２ｂとの間を塞いで虫の侵入を防止するヒレ状の第２の虫除け部材１７ｂが設けられている。なお、虫除け部材１７ａ，１７ｂはモヘアからなっていても良い。
【００１５】
図示例では、収納部８は左右の縦枠２ｃ，２ｄの室内側にそれぞれ別体で設けられ、案内部１０は上枠２ａ及び下枠２ｂの室内側にそれぞれ別体で設けられている。具体的には、サッシ枠である枠体２の室内面にロール式網戸６専用の枠体１８が固着具であるネジ１９ａと連結金具１９ｂを介して着脱自在に取付けられている。このロール式網戸６の枠体１８は、例えばアルミ押出形材からなる上枠材１８ａ、下枠材１８ｂ及び左右の縦枠材１８ｃ，１８ｄからなり、上枠材１８ａと下枠材１８ｂは上枠２ａと下枠２ｂの室内面に取付けられ、左右の縦枠材１８ｃ，１８ｄは左右の縦枠２ｃ，２ｄの室内面に取付けられている。
【００１６】
そして、左右の縦枠材１８ｃ，１８ｄに収納部８，８がそれぞれ設けられ、上枠材１８ａと下枠材１８ｂに左右の可動框９，９に共通の案内部１０，１０が設けられている。上枠材１８ａと下枠材１８ｂの対向面には、長手方向（左右方向）に沿って案内部１０としてのガイド溝２０が設けられている。前記収納部８には網体７を引き出すための引出口部２１が設けられているが、この引出口部２１はガイド溝２０の位置に位置されていることが好ましい。
【００１７】
前記網体７の先端部を可動框９に固定する手段として、図３の（ａ）ないし（ｂ）に示すように網体７の先端部には袋部２８が形成され、この袋部２８に芯材（抜け止め材ともいう）２９が挿入されてこれが前記可動框９に固定されている。具体的には、網体７の先端部は、補強のために折り返されて縫製糸３０ａにより図の上下方向に連通した袋状に縫製されており、この袋部２８を利用して芯材２９が挿入されている。芯材２９は、例えばアルミパイプからなっているが、ある程度の剛性を有する棒状であれば材質は問わない。また、前記網体７の両側縁部（図では上下縁部）は、ガイド溝１６から抜けるのを防止するために図３の（ａ）ないし（ｃ）に示すように折り返されて縫製糸３０ｂにより長手方向（図では左右方向）に連通した袋状に縫製され、袋部３１，３１が形成されている。図１ないし図４に示すように上枠材１８ａ及び下枠材１８ｂのガイド溝２０内には抜け止めガイド棒２２がガイド溝２０内の略中央部から両縦枠材１８ｃ，１８ｄ近傍に向って片持ち梁状に設けられ、収納部８から網体７を引き出してロール式網戸６を閉める時に網体７の両側部の袋部３１，３１に抜け止めガイド棒２２，２２に挿通されるようになっている。
【００１８】
また、網体７の先端部が上下方向に弛んで網体７の先端側に部分的に皺が寄るのを防止するために、網体７の先端側両端部（図示例では上下両端部）が前記可動框９の両端部（同、上下両端部）に固定されている。具体的には、可動框９の両端部には、例えば合成樹脂製の端部キャップ２３が取付けられ、それぞれの端部キャップ２３には網体７の先端側端部を挟んで固定する一対の挟持片２４ａ，２４ｂが設けられている。両挟持片２４ａ，２４ｂの対向面には網体７の滑り止めのために互いに係合する凹凸部２５が形成されている。
【００１９】
前記可動框９は、例えばアルミニウム押出形材からなり、内部には網体７の先端部の芯材２９を長手方向から収容保持する収容部２６と、網体７の先端部を収容部２６に引入れるスリット２７と、連動軸１３を挿通収容する室内側に開口した収容溝部３２とが形成されている。また、可動框９の戸先側には、前記収容溝部３２の一側壁を形成しつつ室内側に突出された把手部３３が形成されている。この把手部３３は薄板状で可動框９の長手方向に沿って長尺に形成されている。
【００２０】
図６の（ａ）は可動框の端部キャップを示す斜視図、（ｂ）は端部キャップのケース部内を示す斜視図、図７の（ａ）はケース部内の停止機構を示す正面図、（ｂ）は（ａ）のＤ-Ｄ線断面、図８は停止機構の概略的斜視図、図９はピニオン及び連動軸を示す斜視図、図１０はレバーキャップの斜視図、図１１は係止部の平面図である。本実施例では前記端部キャップ２３内に、前記収納部８から網体７を引き出しながら移動操作される可動框９を障子３ａ，３ｂの戸先框４ｄと対応する任意の位置に固定する手段としての停止機構１４が設けられている。この停止機構１４は、前記連動軸１３に設けられた係止受部３５と、該係止受部３５に係脱自在に係合して回転を止める係止部３６と、該係止部３６を操作する操作部３７とを有している。
【００２１】
ピニオン１２は、図９に示すように所定長さの回転軸であるピニオン軸３８を一体に有しており、前記連動軸１３の両端部に両ピニオン１２，１２のピニオン軸３８，３８が嵌合連結されている。図示例の連動軸１３は中空に形成され、ピニオン１２の軸方向の移動を許容しつつ回転を伝えるために、ピニオン軸３８の外周には軸方向にキー溝４０が設けられ、連動軸１３の内周にはキー溝４０に係合するキー４１が突設されている。ピニオン軸３８を含むピニオン１２は、施工誤差を吸収し得るように端部キャップ２３に対して軸方向に所定量例えば４ｍｍ程度移動可能に支持されている。前記ピニオン軸３８には、ピニオン１２の近傍にガイド溝２０の溝縁部２０ａに沿って摺動自在に係合する環状溝４２が設けられ、ピニオン軸３８の略中間部にはその外周に歯車状の係止受部３５が設けられている。
【００２２】
前記ピニオン軸３８の外周には、図７、図８、図１０ないし図１１に示すように操作部３７を構成するレバー部４３及び係止部３６を備えた略円筒状のレバーキャップ４４が回動自在に遊嵌されている。レバーキャップ４４には、その軸方向から前記係止部３６の両面（図示例では上下両面）を挟んで支持する一対の支持腕部４５と、両支持腕部４５間の周壁に開口した開口部４６とが形成されている。この開口部４６において係止受部３５と係止部３６とが対向しており、開口部４６を通じて係止部３６がレバーキャップ４４内部の係止受部３５に臨んでいる。前記支持腕部４５の上下対向面間には一対の支持軸部４７が突設され、前記係止部３６の上下両面には前記支持軸部４７が摺動自在に係合する左右方向に傾斜したカム面４８ａを有するカム溝４８が形成されている。係止部３６の前部には歯車状の係止受部３５の歯溝３５ａに係合することが可能な突起３６ａが突設されている。すなわち前記係止部３６は直方体状であり、その前面中央部に突起３６ａが形成され、上下両面にカム溝４８が形成され、後面中央部に後述のバネ４９の一端を挿入する凹部６５が形成されている。
【００２３】
また、係止部３６の後部には突起３６ａが歯溝３５ａに係合する方向に係止部３６を付勢する付勢手段であるバネ４９が設けられている。このバネ４９の付勢力によって前記支持軸部４７に前記カム溝４８のカム面４８ａが当接されている（図１１参照）。レバー部４３によりレバーキャップ４４を一方向（図６の図示例では反時計方向）に回すと支持軸部４７が図１１に示すようにカム溝４８内を左端から右端に移動し、バネ４９によって係止部３６のカム面４８ａが支持軸部４７に対して当接付勢されていることから、カム面４８ａに従って係止部３６がバネ４９の力で係合方向（突起３６ａ側の前面が前方、図１１の紙面上方）に移動される。係止部３６の突起３６ａが係止受部３５の歯溝３５ａに係合すると、連動軸１３が回転不能となるため、可動框９が移動不能（停止状態）となる。前記とは逆にレバーキャップ４４を他方向（時計方向）に回すと支持軸部４７が図１１のカム溝４８内を右端から左端に移動し、この支持軸部４７の移動に伴って前記とは逆に係止部３６がバネ４９の力に抗して反係合方向（歯溝３５ａから突起３６ａが離脱ないし離間する方向、図１１の紙面下方）に移動されるようになっている。係止部３６の突起３６ａが係止受部３５の歯溝３５ａから離間すると、連動軸１３が回転可能となるため、可動框９が移動可能となる。なお、図６は、図２における右側のロール式網戸の下側の端部キャップを示している。
【００２４】
この場合、可動框９に強い衝撃ないし外力が加わったときに、停止機構１４が破損、すなわち係合状態の係止受部３５の歯３５ｂや係止部３６の突起３６ａが破損するのを防止するために、歯溝３５ａ及び突起３６ａの少なくとも一方には噛合が外れ易いようにテーパー（傾斜）が設けられていると共に、係止部３６のカム溝４８には係止部３６の反係合方向への移動（逃げ）を許容するための逃げ部ｄ（図１１参照）が形成されている。
【００２５】
前記レバーキャップ４４には、これを係止部３６の反係合方向である反時計方向に付勢する付勢手段であるバネ５０が設けられている。従って、係止部３６の係合状態を解除する場合には、レバー部４３をバネ５０の付勢力に抗して時計方向に回動操作すれば良く、レバー部４３を解放するとレバー部４３が待機位置に自動的に復帰し、係止部３６が係止受部３５に対して係合するようになる。前記端部キャップ２３は、一側方が開放されたケース部５１と、その開放部を覆うように取付けられる２つの蓋部５２，５３とからなっており、そのケース部５１内に前記レバーキャップ４４が回動自在に支持されていると共に係止部３６がピニオン軸３８の半径方向に摺動自在に支持されている。
【００２６】
前記端部キャップ２３のケース部５１には前記可動框９の把手部３３の長手方向両端部がそれぞれ係合する係合溝部５４ａを有する把手部端部受部５４が設けられている。また、前記レバー部４３には、可動框９に沿って長尺の操作摘み部５５の長手方向両端部がそれぞれ係合する係合溝４３ａが設けられている。操作摘み部５５は、例えばアルミ押出形材からなっており、基端部には収容溝部３２内の連動軸１３の外周に回動自在（摺動自在）に係合支持される断面略Ｃ字状の支持部５５ａが設けられている（図５参照）。操作部３７は、レバー部４３と、操作摘み部５５とにより構成されている。
【００２７】
すなわち、可動框９には前記把手部３３が設けられていると共に停止機構１４を操作する操作部３７が設けられている。この操作部３７は、可動框９の長手方向両端部に取付けられた端部キャップ２３におけるレバーキャップ４４のレバー部４３と、これら上下で対をなすレバー部４３，４３の係合溝４３ａに両端部を係合させて取付けられた操作摘み部５５とから構成されている。操作摘み部５５は、把手部３３と同様、可動框９の長手方向に沿って長尺な部材として配置されている（図１、図２、図６（ｂ）参照）。前記把手部３３は、可動框９の長手方向両端部に取付けられた端部キャプ２３のケース部５１に設けられて上下で対をなす把手部端部受部５４の係合溝部５４ａに両端部を係合させて取付けられている（図１、図２、図６（ｂ）参照）。実施例の場合、通常時には停止機構１４は停止状態（作動状態）になるように、且つ操作摘み部５５は待機位置に位置するように停止機構１４のバネ４９により付勢されており、操作摘み部５５を待機位置から操作することにより停止機構１４の停止状態（作動状態）を解除できるようになっている。操作摘み部５５は、可動框９の把手部３３と操作摘み部５５を指で摘んで操作摘み部５５を把手部３３側に回すと、停止機構１４の作動状態（係止部と係止受部が係合した状態）を解除することができ、可動框９を任意の位置まで移動することができ、操作摘み部５５を離す（解放する）とバネ４９の付勢力で待機位置に復帰して停止機構１４が作動状態になる。
【００２８】
ところで、可動框９の両端にピニオン１２を配置し、両ピニオン１２を連動軸１３で連結したものにおいては、万が一、片方のピニオン１２が例えばごみを噛んで動かなくなった時に無理に可動框９を動かそうとしたり、或いは可動框９の片側に通常の操作以上の強い衝撃を加えたりして、一方のピニオン１２とラック１１の噛合部に強い力が加わり、ピニオン１２とラック１１の歯の破損や噛合いのずれ（歯飛び）が発生する場合がある。
【００２９】
そこで、この問題を解消するために、図１２に示すように少なくとも一方のピニオン１２と連動軸１３の間には一方のピニオンに加わる無理な力を吸収する吸収部材としての捻りバネ５６が設けられている。この場合、一方のピニオン１２と連動軸１３の間に接続部材６０が設けられ、この接続部材６０に捻りバネ５６が組込まれている。この接続部材６０は、前記ピニオン１２のピニオン軸３８に嵌合するキー付嵌合孔部６１ａを有する第１部材６１と、前記連動軸１３の一端に挿入嵌合するキー溝付嵌合軸部６２ａを有する第２部材６２とを有している。第１部材６１には第２部材６２の軸端に突設された突軸部６２ｂを回動自在に嵌合する軸孔部６１ｂが設けられている。前記第１部材６１と第２部材６２の間の前記突軸部６２ａ上に捻りバネ５６が遊嵌され、捻りバネ５６の一端が第１部材６１に、捻りバネ５６の他端が第２部材６２にそれぞれ止着されている。可動框９の通常の開閉操作では捻りバネ５６は微少に捻じれが発生するだけで、可動框９に微少な傾きが発生するが、操作性に影響するほどではない。
【００３０】
以上の構成からなる開口部装置１ないしロール式網戸（ロール式遮蔽装置）によれば、ロール式網戸６が、巻取可能な網体７と、該網体７を巻取って収納する収納部８と、該網体７を前傾収納部８から引き出し入れする可動框９と、該可動框９の両端部を摺動自在に案内する案内部１０，１０と、それぞれの案内部１０，１０に設けられたラック１１，１１と、それぞれのラック１１，１１に噛合するピニオン１２，１２と、前記可動框９に沿って回転自在に支持され前記両ピニオン１２，１２を連結する連動軸９と、前記可動框９を任意の位置に停止させる停止機構１４とを備え、前記可動框９に前記停止機構１４を操作するための操作部３７を設け、該操作部３７が可動框９の長手方向に沿って長尺に形成されているため、可動框９の長手方向の何れの位置でも操作摘み部５５を操作することができ、操作性に優れる。
【００３１】
すなわち、前記可動框９には、前記操作部３７として、可動框９の長手方向に沿って長尺の操作摘み部５５が設けられているので、可動框９の長手方向の何れの位置でも操作摘み部５５を容易に操作して停止機構１４の停止状態を解除することができ、可動框９を容易に操作してロール式網戸６を容易に開閉操作することができ、操作性の向上が図れる。また、案内部１０，１０にラック１１，１１を設け、これらのラック１１，１１に噛合するピニオン１２，１２を可動框９の長手方向両端部に設け、両ピニオン１２，１２を連動軸１３で連結したので、可動框９を容易に且つ円滑に平行移動させることができ、ロール式網戸６の操作性の向上が図れる。更に、実施例では、停止機構として摩擦式の制動部材を使用していないので、制動部材の摩耗等の耐久性の低下を招いたり、施工や製作の精度、砂や埃等によって品質にバラツキが出たりすることがない。また、障子の戸先框に可動框をラッチ部品等で係止する構造と異なり、障子が軽い場合でも、可動框や障子が網体の巻取り用のバネの力で勝手に動いてしまうという不具合を発生することもない。
【００３２】
前記停止機構１４の歯車状の係止受部３５の歯溝３５ａ及びその歯溝３５ａに係合する係止部３６の突起３６ａの少なくとも一方にテーパーを設けて噛合が外れ易くすると共に、係止部３６のカム溝４８に係止部３６の反係合方向への移動（逃げ）を許容するための逃げ部ｄが形成されているため、可動框９に強い衝撃ないし外力が加わったときに、停止機構１４が破損、すなわち係合状態の係止受部３５の歯３５ｂや係止部３６の突起３６ａが破損するのを防止することができ、耐久性の向上が図れる。
【００３３】
以上、本発明の実施の形態を図面により詳述してきたが、本発明は前記実施の形態に限定されるものではなく、本発明の要旨を逸脱しない範囲での種々の設計変更等が可能である。例えば、本発明は、引違い窓だけでなく、片引き窓、縦辷り窓、障子が上下方向に開閉自在に設けられた上げ下げ窓等にも適用することが可能である。また、ロール式網戸（ロール式遮蔽装置）は横引きタイプだけでなく、縦引きタイプであっても良い。更に、前記実施の形態ではロール式網戸を２つ用いて両開き式に構成した例が示されているが、片引き式に構成したものであっても良い。また、ロール式網戸の収納部や案内部は、サッシ枠の枠体に一体形成ないし一体に設けられていても良い。
【００３４】
開口部装置としては、サッシとは別体で、ロール式網戸（ロール式遮蔽装置）のみからなっていても良い。ロール式遮蔽装置としては、ロール式網戸以外に、例えばロールスクリーン等であっても良い。また、遮蔽材としては、網や網体以外に、例えば布やスクリーン等であっても良い。本発明においては、停止機構の構造が限定されていないので、停止機構としては、実施例の歯車式が好ましいが、既存の摩擦制動式であっても良い。また、操作部である操作摘み部は、室内側正面を向いた待機位置にあり、その待機位置から左側または右側に回動操作することにより停止機構を解除するように構成されていても良い。なお、本発明は、案内部に設けられたラックと、ラックに噛合するピニオンと、可動框に沿って回転自在に支持され両ピニオンを連結する連動軸とを備えていないロール式遮蔽装置や開口部装置にも適用することが可能である（請求項１、請求項３）。

以上要するに本発明によれば、次のような効果を奏することができる。
