Description

【０００１】
【発明の属する技術分野】
本発明は、建物開口部に取付けられ雨戸などとして用いられる窓用のシャッターに関する。
【０００２】
【従来の技術】
特許文献１に開示された窓用のシャッターが知られている。
このシャッターは、シャッター枠にシャッターカーテン（シャッター板）を昇降自在に取付けてシャッター枠を開放・閉塞できるようにし、そのシャッター枠の上枠と下枠に亘って中柱を取付け、この中柱とシャッターカーテンを形成するいくつかのスラットの室内側面を固定部材で連結し、耐負圧性を向上したものである。
かかるシャッターであれば、台風等の強風雨によってシャッターカーテンに大きな負圧（室内側から室外側に向う力）が作用した時に、シャッターカーテンがその負圧によって室外側に向けて大きくたわむことを中柱で防止できるから、シャッターカーテンがシャッター枠から外れることがない。
【０００３】
特許文献２に開示された出入口用のシャッターが知られている。
このシャッターは、シャッター枠にシャッターカーテンを昇降自在に取付け、そのシャッター枠上部のシャッターケースの見付け方向中間部と床部とに亘って杆体を取付けたものである。
かかるシャッターであれば、シャッターカーテンの室外側に杆体が位置するから、この杆体でシャッターカーテンの耐負圧性をある程度向上できる。

【０００５】
【発明が解決しようとする課題】
前述した特許文献１に開示されたシャッターであると、シャッターカーテンを形成するいくつかのスラットと中柱を固定部材で固定してあるので、耐負圧性を向上した状態ではシャッターカーテンを昇降して開閉できない。
また、耐負圧性を向上するには中柱を取付けると共に、中柱とシャッターカーテンを形成するいくつかのスラットを固定しているので、その耐負圧性を向上するための操作が面倒である。
また、シャッターカーテンはシャッター枠の室外側部に設けられ、そのシャッター枠の室内側部には障子戸、網戸などの部材が設けてあるので、それらの部材とシャッターカーテンとの間のスペースに中柱を取付けてあるから、その中柱の見込み寸法が限られ、耐負圧性の向上に限度がある。
【０００６】
前述した特許文献２に開示されたシャッターであると、杆体の上部が剛性の弱いシャッターケースの見付け方向中間部に固定されるので、その杆体の上部の固定強度が弱く、耐負圧性の向上に限度がある。
また、杆体をシャッターカーテン室外側面に接近して取付けるために、杆体の上部はシャッターケースにおけるシャッターカーテンよりも室外側に突出した部分に固定されるので、杆体の見込み寸法がシャッターケースの突出部分の寸法によって制限され、耐負圧性向上に限度がある。
【０００７】
本発明は、前述の課題に鑑みなされたものであり、その目的は、耐負圧性を向上した状態でシャッターカーテンを昇降して開閉できること、簡単な操作で耐負圧性を向上できること、耐負圧性を十分に向上できることを満足したシャッターを提供することである。
【０００８】
【課題を解決するための手段】
本発明は、シャッター枠１の上部にシャッターボックス１４を有し、前記シャッター枠１にシャッターカーテン２を昇降自在に設け、このシャッターカーテン２を前記シャッターボックス１４内で巻き取り、繰り出しすることで、前記シャッター枠２を開放、閉塞するシャッターにおいて、
前記シャッター枠１の見付け方向両側における上部室外側部分に固着される取付用横部材３と、
この取付用横部材３の長手方向中間部とシャッター枠１の下部室外側部分における見付け方向中間部に亘って取付けられ、前記シャッターカーテン２の室外側面と対向している補強縦部材を備え、
前記取付用横部材３の長手方向両端部に上部取付ブラケット５がそれぞれ固着され、この各上部取付ブラケット５がシャッター枠１の左右の縦枠１２の室外側部分にそれぞれ固着してあり、
前記シャッター枠１の下枠１１における室外側部の見付け方向中間部に下部取付ブラケット６が固着され、
前記補強縦部材４の上部を取付用横部材３に固定する上部固定部材８と、その補強縦部材４の下部を前記下部取付ブラケット６に固定する前記下部固定部材７を設け、
前記上部固定部材８は、補強縦部材４よりも上方に突出した杆体６６を取付用横部材３の孔に嵌合するもので、
前記下部固定部材７は、杆体６０を下部取付ブラケット６の孔に嵌合する位置と抜け出す位置とに亘って上下動自在としたものであることを特徴とするシャッターである。
【００１２】
【作用】
本発明によれば、台風等の強風雨によってシャッターカーテン２に大きな負圧が作用し、そのシャッターカーテン２が室外側に向けて大きくたわむことを補強縦部材４で防止できるから、耐負圧性を向上できる。
また、補強縦部材４はシャッターカーテン２の室外側面と対向しているだけであるから、前述のように耐負圧性を向上した状態でシャッターカーテン２を昇降して開閉できる。
また、取付用横部材３と下枠１１に亘って補強縦部材４を取付けることで、耐負圧性を向上できるから、簡単な操作で耐負圧性を向上できる。
また、補強縦部材４の見込み寸法、見付け寸法には何らの制約がないから、それらの寸法の大きな補強縦部材４を取付けて耐負圧性を十分に向上できる。
【００１３】
また、取付用横部材３に固着した上部取付ブラケット５を縦枠１２に固着し、下枠１１に下部取付ブラケット６を固着し、その下部取付ブラケット６と取付用横部材３に亘って補強縦部材４を取付けるので、既存のシャッター枠１に補強縦部材４を取付けることができ、既設のシャッターの耐負圧性を簡単に向上できる。
【００１５】
また、下部固定部材７の杆体６０を抜け出し位置として上部固定部材７の杆体６６を取付用横部材３の孔に嵌合すると共に、補強縦部材４の下部を下部取付ブラケット６に載置して支持し、その後に下部固定部材６の杆体６０を下部取付ブラケット６の孔に嵌合することで、補強縦部材４を取付けできる。
また、前述と反対の操作で補強縦部材４を取り外しできる。
【００１６】
【発明の実施の形態】
図１に示すように、シャッター枠１にシャッターカーテン２を昇降自在に設けてシャッター枠１を開放、閉塞自在としている。
前記シャッター枠１の見付け方向両側における上部室外側部分に取付用横部材３の長手方向両端部分がそれぞれ固着してある。
この取付用横部材３の長手方向中間部、好ましくは長手方向中央部とシャッター枠１の下部室外側部分における見付け方向中間部、好ましくは見付け方向中央部とに亘って補強縦部材４を取付け、好ましくは着脱自在に取付ける。
この補強縦部材４はシャッターカーテン２の室外側面と対向している。
【００１７】
このようであるから、台風等の強風雨によってシャッターカーテン２に大きな負圧が作用した時に、そのシャッターカーテン２が負圧によって室外側に向けてたわむと補強縦部材４に当接して、それ以上たわむことがない。
よって、強風雨等によってシャッターカーテン２が室外側に大きくたわむことを防止できる。
【００１８】
図１に示す実施の形態では、取付用横部材３の長手方向両端部に上部取付ブラケット５がそれぞれ固着され、この各上部取付ブラケット５がシャッター枠１の見付け方向両側における上部室外側部分にそれぞれ固着されている。
前記シャッター枠１の下部見付け方向中間部に下部取付ブラケット６が固着され、この下部取付ブラケット６に補強縦部材４の下部が下部固定部材７で着脱自在に固着される。
前記補強縦部材４の上部は、上部固定部材８で取付用横部材３の長手方向中間部に着脱自在に固着される。
前記取付用横部材３の長手方向中間部にはガイド部材９が取付けられ、このガイド部材９に補強縦部材４の上部が嵌まり込み、長手方向に位置決めするようにしてある。
【００１９】
次に、各部材の具体形状の一例を説明するが、これに限ることはない。
前記シャッター枠１は図１、図２、図３に示すように、上枠１０と下枠１１と左右の縦枠１２を有し、その左右の縦枠１２はシャッターカーテン２を昇降自在にガイドするガイド部、例えばガイドレール１３を備えている。
この実施の形態では、図３に示すように引き違いサッシ窓のサッシ枠における縦枠の室外側部にガイドレール１３を取付けてシャッター枠１としてあり、シャッター枠１はその室内側部に障子が引き違いに装着できると共に、その室外側部にシャッターカーテン２が昇降自在に設けられ、シャッター付きサッシ窓を形成している。
これに限ることはなく、シャッター枠１とサッシ枠を別々とし、シャッター枠１を建物開口部に直接取付けるようにしても良いし、シャッター枠１をサッシ枠に取付けるようにしても良い。
【００２０】
前記シャッター枠１は、その上部にシャッターボックス１４を備え、このシャッターボックス１４内に巻取り軸１５が回転自在に設けてある。
この巻取り軸１５でシャッターカーテン２が巻取り、繰り出しされる。
前記シャッターボックス１４は図２に示すように縦枠１２の上枠１０から突出した部分と、上面板１６と、側面板１７と、カバー１８で形成され、そのカバー１８は開閉自在である。例えば、カバー１８の上端部が上面板１６の室外側部に上下回動自在に支持され、下部１８ａがビス１９で固着してある。
前記カバー１８の下部１８ａ室内側部と上枠１０の室外側部との間にシャッターカーテン２が出入する開口部２０が形成してある。
【００２１】
前記シャッターカーテン２は複数のスラット２１を連結したもので、その最下部のスラット２１に座板２２が設けてあり、最上部のスラット２１が前記開口部２０を通って前記巻取り軸１５に連結される。
前記巻取り軸１５を一方向に回転してシャッターカーテン２を巻き取ることで上昇して開放し、他方向に回転することでシャッターカーテン２が繰り出して下降し閉塞する。
【００２２】
前記取付用横部材３は図２に示すように、前述の開口部２０よりも室外側に設けられ、かつカバー１８の下部１８ａに接近している。
これによって、前述の開口部２０から鳥などがシャッターボックス１４内に入り込むことが取付用横部材３で防止される。
前記取付用横部材３の室内側面３ａにはモヘヤなどの消音材２３が装着してある。この消音材２３にシャッターカーテン２の室外側面が接して干渉音を低減する。
【００２３】
また、図２に示すように、シャッターカーテン２を最大限巻き取って全開した状態において、座板２２の下端面と取付用横部材３の下面がほぼ同一高さ、好ましくは同一高さであるから、全開状態の時の開口高さが取付用横部材３によって低くなることがない。
なお、取付用横部材３の下面を座板２２の下端面よりも上方としても良いし、下方としても良いが、前述のようにほぼ同一高さとすることで、取付用横部材３の上下寸法を大きくできるから剛性が大きくなるので、強度上好ましい。
【００２４】
前記上部取付ブラケット５は、図２、図４、図５に示すように、第１取付部５ａと第２取付部５ｂと仮取付部５ｃを備え、その第１取付部５ａが取付用横部材３の長手方向端部に固着され、第２取付部５ｂが縦枠１２の室外側部（ガイドレール１３）に固着され、仮取付部５ｃがシャッターボックス１４、例えばカバー１８の下部１８ａに仮取付けされる。
例えば、前記第１取付部５ａは取付用横部材３の端面形状に合致した板状で、取付用横部材３は中空断面で、その内面上下にビスホール３０を有する長尺材で、第１取付部５ａから上下のビスホール３０にビス３１を螺合して固着し、中空部を第１取付部５ａで閉塞する。
例えば、第２取付部５ｂは第１取付部５ａの室内側部と連続した平面ほぼ鉤形の板状で、縦枠１２の室外側部の室外側面１２ａ、側面１２ｂ（ガイドレール１３の室外側面１３ａ、側面１３ｂ）に接し、ビス３２で固着される。例えば、ガイドレール１３の中空基部１３ｃ内に裏板３３を設け、この裏板３３にビス３２を螺合して固着する。
【００２５】
前記仮取付部５ｃは第１取付部５ａの上部と連続した横向き板状で、その室内側に開口した溝３４を有する。
この溝３４を前記カバー１８の下部１８ａを固着するビス１９に挿通することで仮取付けられる。
そして、前記ビス１９を締付けることでカバー１８の下部１８ａに固着される。
【００２６】
このようであるから、取付用横部材３に上部取付ブラケット５を固着した状態で、その取付用横部材３を持ち上げて仮取付部５ｃの溝３４をビス１９に挿通することで仮取付けし、その状態で第２取付部５ｂをビス３２で固着すると共に、ビス１９を締付けて固着することができる。
よって、取付用横部材３を１人の作業者で容易に取付けできる。
なお、前述のようにして取付ける際にはビス１９を若干弛めておく。
また、ビス１９を弛めることでカバー１８を開放することができる。
【００２７】
前記補強縦部材４は図３に示すように中空の長尺材である。例えば、室内側板３５と室外側板３６と左右板３７で所定の見込み寸法と見付け寸法を有する矩形断面の中空の長尺材で、その上下に小口キャップ３８がそれぞれ取付けてある。前記室内側板３５にはモヘヤなどの消音材３９が装着してあり、この消音材３９はシャッターカーテン２の室外側面に接して干渉音を低減する。
このように、補強縦部材４を中空の長尺材としたのは、軽量で剛性大とするためであり、中実の長尺材であっても良い。
【００２８】
前記下部取付ブラケット６は図２、図３、図６に示すように、取付部６ａと支持部６ｂを有し、その取付部６ａが下枠１１に固着され、支持部６ｂが下枠１１よりも室外側に突出する。そして支持部６ｂに補強縦部材４の下部が接して支持する。好ましくは、支持部６ｂは補強縦部材４の下部が嵌まり込む凹部を有する。
例えば、下部取付ブラケット６は取付部材４０と、支持部材４１を備えている。
前記取付部材４０は所定の幅を有する板状で、その室外側部には幅方向一対の立上り片４２を有し、かつ幅方向中央部に孔４３が形成してあり、中間部には室内側に向う係止片４４を有し、室内側部に取付用孔４５を有する。
前記係止片４４は板材を切り越して形成してある。
前記支持部材４１は横板４６と見付け方向一対の縦板４７で上向きコ字形状で、その横板４６には孔４８が形成されていると共に、室内側寄りに見込み方向の位置決め部、例えば突片４６ａが形成され、一対の縦板４７には下面に開口した溝４９が形成してある。この一対の縦板４７の間隔は補強縦部材４の見付け寸法とほぼ同一で、補強縦部材４の左右板４７が接するようにしてある。つまり、補強縦部材４の見付け方向両面が嵌まり込む凹部を形成している。
前記取付部材４０の一対の立上り片４２と支持部材４１の一対の溝４９を嵌め合せて支持部材４１を取付部材４０の室外側部に取付け、その横板４６と取付部材４０をビス５０で固着する。各孔４３，４８が連続する。この実施の形態では孔４８の周縁部に筒状部４８ａが一体的に設けてあり、この筒状部４８ａが孔４３に嵌合し、杆体６０が孔４８に嵌合するようにしてある。
前記取付部材４０は金属製、支持部材４１は樹脂製であるが、これに限ることはない。
【００２９】
そして、取付部材４０の室内側部を下枠１１の下面に接すると共に、係止片４４を下枠１１の室外側突片部１１ａに係止して仮取付けする。
この状態で取付用孔４５からビス５１を下枠１１に螺合して取付け、支持部材４１を下枠１１よりも室外側に突出させる。
このようであるから、下部取付けブラケット６を下枠１１に容易に取付けできる。
【００３０】
前記下部固定部材７は、図７に示すように前記支持部材４１の孔４８（つまり、支持部６ｂの孔）に挿入、抜き出し自在な杆体６０を有し、その杆体６０を孔４８に挿入することで補強縦部材４の下部を下部取付ブラケット６に固定し、室内外側方向（見込み方向）、左右方向（見付け方向）に動かないようにする。
例えば、補強縦部材４の中空部にホルダー６１を設け、このホルダー６１に杆体６０を上下動自在に支承すると共に、杆体６０が小口キャップ３８の孔３８ａから下方に突出するようにする。
前記杆体６０に連結材６２を固着し、この連結材６２を補強縦部材４の中空部に上下動自在とし、補強縦部材４の室内側板３５に形成した上下方向の長孔６３から操作部材６４を連結材６２に固着することで、その操作部材６４を持って上下に移動することによって杆体６０を上下に移動できるようにする。
例えば、操作部材６４を摘み６４ａにねじ６４ｂを設けたものとし、そのねじ６４ｂを前述の長孔６３から連結材６２に螺合する。そして、ねじ６４ｂを締付けることで固定し、弛めることで上下に移動できるようにする。
【００３１】
前記上部固定部材８は、図８に示すように補強縦部材４の中空部の上方に固定した連結材６５に杆体６６を固定し、その杆体６６を小口キャップ３８の孔３８ａを貫通して上方に突出したもので、その杆体６６が取付用横部材３の下面の孔に嵌合される。
この実施の形態では、ガイド部材９を取付けてあるので、そのガイド部材９の孔に嵌合される。
【００３２】
前記ガイド部材９は図５と図８と図９に示すように、前記補強縦部材４の上部が嵌まり合う下向きの凹部９ａを有し、その凹部９ａに補強縦部材４の上部を嵌め込むことで見付け方向に位置決める。
例えば、ガイド部材９は本体７０とプレート７１を備え、その本体７０は横板７０ａと見付け方向一対の下向片７０ｂで下向きコ字形状で、その横板７０ａに孔７２とビス挿通孔７３が形成してある。なお、一対の下向片７０ｂの下端部分は外側に向けて斜めで、補強縦部材４の上部を嵌め込み易くしてある。
前記プレート７１には孔７４とビス挿通孔７５が形成され、このプレート７１を横板７０ａの下面に接し、ビス７６をビス挿通孔７５，７３を挿通して取付用横部材３の下面３ｂに螺合することで本体７０とプレート７１が連結されると共に、ガイド部材９が固着される。
そして、横板７０ａの孔７２とプレート７１の孔７４が連通し、この孔７２，７１に前記杆体６６が嵌合する。
【００３３】
前記本体７０の一対の下向片７０ｂの間隔は補強縦部材４の見付け寸法とほぼ同一で、その一対の下向片７０ｂ間（凹部９ａ）に補強縦部材４が嵌め込まれて左右板３７が一対の下向片７０ｂの対向内面に接することで見付け方向に位置決めされる。
この実施の形態では、プレート７１の孔７４の周縁部には筒状部７４ａが一体的に設けられ、その筒状部７４ａが孔７２及び取付用横部材３の下面に形成した孔７７に嵌合するようにしてあり、前述の杆体６６はプレート７１の孔７４に嵌合する。
【００３４】
次に、補強縦部材４の取付け方の一例を説明する。
下部固定部材７の杆体６０を上方に移動して補強縦部材４の中空部内に収納する。
この状態で、補強縦部材４を上方に移動して上部固定部材８の杆体６６の小口キャップ３８から突出した部分を孔７４に嵌合しながら一対の下向片７０ｂ間に嵌め込むと共に、補強縦部材４の下部を下部取付ブラケット６の一対の縦板４７間に嵌め込んで横板４６に載置し、室内側板３５又は小口キャップ３８、つまり室内側部分を突片４６ａに接して見込み方向に位置決めする。
この後に、下部固定部材７の杆体６０を孔４８に嵌合して補強縦部材４の下部を下部取付ブラケット６に固定する。
【００３５】
前記補強縦部材４を取り外す場合には、前述と反対の操作を行なえば良い。
【００３６】
なお、取付用横部材３を取付けブラケットでカバー１８に固着しても良い。
また、上部取付けブラケット５をシャッターケース１４の内部に設けた巻取り軸取付用の端面板に固着しても良い。
【００３７】
【発明の効果】
請求項１に係る発明によれば、台風等の強風雨によってシャッターカーテンに大きな負圧が作用し、そのシャッターカーテンが室外側に向けて大きくたわむことを補強縦部材で防止できるから、耐負圧性を向上できる。
また、補強縦部材はシャッターカーテンの室外側面と対向しているだけであるから、前述のように耐負圧性を向上した状態でシャッターカーテンを昇降して開閉できる。
また、取付用横部材と下枠に亘って補強縦部材を取付けることで、耐負圧性を向上できるから、簡単な操作で耐負圧性を向上できる。
