Description

【0001】
【発明の属する技術分野】
本発明は、主として建物の外壁におけるサッシ窓の上部に取付けられ雨戸として利用される電動式シャッターに関する。
【0002】
【従来の技術】
電動式シャッターとしては、シャッターケースと、このシャッターケース内に設けた巻取ドラム及び巻取ドラムを駆動する電動機と、前記巻取ドラムで巻き取り、繰り出しされるシャッターカーテンを備えたものが知られている。
この電動式シャッターにおいては、建物側から電動機に電線が接続され、その電線がシャッターケース内でシャッターカーテンと干渉する虞れがある。
【0003】
このことを解消できるようにした電動式シャッターが提案されている。
例えば、特開2000−192757号公報に示す電動式シャッターが提案されている。
この電動式シャッターは、シャッターケースの建物側の開口部に仕切板を取付け、この仕切板の裏面に電線が取付け、この電線をシャッターケース内部の電動機に接続してある。
これによって、シャッターカーテン(スラット)と電線が仕切板で仕切りされるから、電線がシャッターケース内でシャッターカーテンと干渉することがない。
【0004】
【発明が解決しようとする課題】
前述した従来の電動式シャッターにおいては、シャッターカーテンの長手方向端部とシャッターケースの端面との間を電線が通るので、シャッターカーテンが巻き取り軸に対して長手方向にずれ(横ずれ)が生じた場合に、その電線がシャッターカーテンの長手方向端部と干渉することがある。
【0005】
本発明は前述の課題を解決するためになされたものであって、その目的は、シャッターカーテンの横ずれを防止できると共に、そのシャッターカーテンと電線が干渉することを防止できる電動式シャッターを提供することである。
【0006】
【課題を解決するための手段】
発明は、シャッターケースと、このシャッターケース内に設けた巻取部及びその巻取部を駆動する電動機と、前記巻取部で巻き取り、繰り出しされるシャッターカーテンと、前記シャッターケースの側面板の内面に前記巻取部の周囲を囲むように取付けたシャッターカーテン横ずれ防止部材を備え、
このシャッターカーテン横ずれ防止部材は、巻取部の周囲にほぼ連続したガイド面を有すると共に、側面板の内面との間に電線挿通空間部を形成する形状で、
この電線挿通空間部に電線が配設され、
前記シャッターケースは開閉自在な前面板を備え、
シャッターカーテン横ずれ防止部材における前面板と対向した一部分が着脱自在で、
この一部分で形成された電線挿通空間部に、電線のコネクタ部分が位置することを特徴とする電動式シャッターである。
【0008】
【作用】
発明によれば、シャッターカーテンの巻き取り、繰り出し時にシャッターカーテン横ずれ防止部材のガイド面に接触することで、シャッターカーテンの横ずれが防止される。
また、シャッターケースの側面板の内面とシャッターカーテン横ずれ防止部材との間に電線挿通空間部が形成され、この電線挿通空間部に電線が配設されているので、シャッターカーテンの巻き取り、繰り出し時にシャッターカーテンと電線が干渉することがない。
【0009】
また、シャッターケースの前面板を開放した状態でシャッターカーテン横ずれ防止部材の一部分を取り外しすることで、コネクタ部分が外部に露出する。
よって、シャッターケースの開口部から電線を接続することができる。例えば、サッシ枠の上部にシャッターケースを取付けた状態で、縦枠側に設けたテープスイッチに接続した電線をシャッターケース内の電線に接続できる。
【0010】
また、前述の一部分を取付けることでコネクタ部分がカバーされるので、そのコネクタ部分に直接雨水などがかかることが防止される。
しかも、前述のような電線の接続作業時にシャッターカーテンは邪魔にならないので、そのシャッターカーテンを巻き取った状態で接続作業できる。
【0011】
【発明の実施の形態】
図1に示すように、サッシ窓を形成するサッシ枠1は左右の縦枠2,2と、下枠3と、上枠4を備えている。
前記縦枠2の上部2aは上枠4よりも上方に突出している。
前記縦枠2における上枠4よりも下方部分、つまり下部2bにおける室外側部にガイドレール5が取付けてある。
シャッターは、シャッターケース10と、そのシャッターケース10内に設けた巻取部11と、その巻取部11で巻き取り、繰り出されるシャッターカーテン12と、シャッターケース10内に設けられ巻取部11を駆動する図示しない電動機を備えている。
前記シャッターカーテン12は複数のシャッタースラット12aを連結したもので、前記ガイドレール5に沿って上下動する。
【0012】
前記シャッターケース10は上面板20と左右の側面板21と前面板(正面パネル)22と左右のシャッターカーテン横ずれ防止部材23を備え、この実施の形態では縦枠2の上部2aが側面板20の一部を構成している。
つまり、この実施の形態ではサッシ枠1とシャッターケース10が一体としてあるが、サッシ枠1とシャッターケース10を別体としても良い。
図1はサッシ枠1とシャッターの全体を理解し易くするために概略的に示すもので、各部材の位置関係、寸法などは後述する具体形状とは異なる部分がある。
【0013】
前記サッシ枠1は図2に示すように、建物の外壁6の窓開口部7の周縁に取付けられる。
前記上面板20は外壁6の室外側面6aに取付けられると共に、左右の縦枠2の上部2a間にビスで連結される。
前記側面板21は、縦枠2の上部2aの内面に取付けた内側板24と、この内側板24の外面に取付けた外側板25より成る。
この実施の形態では、内側板24は縦枠2の室外側面2cよりも室外側に突出し、外側板25は縦枠2の室外側面2cと連続している。これは前述のようにシャッターケース10がサッシ枠2と一体であるためで、別体の場合には外側板25を外壁6の室外側面6aまで突出した形状とする。
【0014】
前記内側板24の室外側部には上取付片26、中間取付片27、下取付片28を有し、外側板25の内面に設けた上取付片29、中間取付片30をビス31で前記内側板24の上取付片26、中間取付片27にそれぞれ固着して外側板25が内側板24に取付けられ、前述の側面板21を形成している。
なお、側面板21は内側板24と外側板25を一体とした一枚形状としても良い。
前記巻取部11は中空の軸形状で、その一端部が、一方の内側板24の内面に取付けた電動機13の出力側に連結され、他端部が他方の内側板24に回転自在に取付けてある。
【0015】
前記前面板22は、その上取付突部32が上面板20の室外側に形成した下向きの取付凹部33に上下揺動自在に連結され、前面板22の下部が前記下取付片28にビス34で連結してある。
この前面板22の下部と上枠4の室外側部が室内外側方向に離隔し、その間を各スラット12aが上下に移動する。
よって、ビス34を弛めることで前面板22を上方に揺動してシャッターケース10の開口部10aを開放できる。
なお、図2には前述のシャッターカーテン横ずれ防止部材23の図示が省略してある。
【0016】
前記シャッターカーテン横ずれ防止部材23は図3と図4に示すように、前記巻取部11の周囲を囲むように内側板24の内面(側面板21の内面)に取付けられ、その巻取部11の周囲にほぼ連続したガイド面23aを有すると共に、内側板24の内面との間に電線挿通空間部23bを形成している。前記シャッターカーテン横ずれ防止部材23の一部分23cはシャッターケース10の開口部10aから着脱自在である。
その一部分23cを取り外しすると図3に示すように、前記電線挿通空間部23bの一部分が前面板22側(開口部10a)に開放し、その電線挿通空間部23bに配設した電線、例えば第1電線35のコネクタ部分35aと第2電線36のコネクタ部分36aが外部に露出して接続、分離できるようにしてある。つまり、コネクタ部分35a,36aと対向した一部分23cが着脱自在である。
前記第1電線35の一端部は前記巻取部11を駆動する電動機13に接続し、他端部は図示しない電源側に接続される。この電動機13の電線接続部はガイド面23aよりも内方に突出しないようにしてある。
前記第2電線36の一端部は図示しない縦枠2に設けたテープスイッチ(シャッターカーテン12を繰り出した時に人などに干渉したことを検出するスイッチ)に接続し、他端部は図示しないコントローラに接続される。なお、第2電線36は2本備え、他方の第2電線36はシャッターケース10内における奥部において左右方向に向けて配設され、図5に示すように、反対側のシャッターカン横ずれ防止部材23の電線挿通空間部23bを通って反対側のテープスイッチに接続される。他方の電線36のコネクタ部分36aは一部分23cと対向し、その一部分23cを外すことで開口部10aから接続・分離できる。
【0017】
次に、シャッターカーテン横ずれ防止部材23の具体形状の一例を説明する。
シャッターカーテン横ずれ防止部材23は、図3と図4に示すように、第1部材40と第2部材50と第3部材60を備えている。
前記第1部材40は図3、図4、図6に示すように、ほぼ円孤形状の外周面41aと内周面41bを有する本体部41と、この本体部41の一端面41cにおける内周面41b寄りと連続した円孤状突出部42を有する。

この第1部材40の上方凹部43と内側板24で上空間部49aを形成し、下方凹部44と内側板24で下空間部49bを形成している。
前記上空間部49aは本体41の外周面41aの上部と一端面41cに開口している。
前記下空間部49bは本体41の内周面41bの下部寄りと外周面41aの下部寄りにそれぞれ開口している。
【0019】
前記第2部材50は図3と図4に示すように、ほぼ矩形状で、裏面における長手方向中間部に凹部51に有したほぼ平面コ字形状で、この凹部51よりも両側に取付用穴52がそれぞれ形成してある。
この第2部材50は内側板24の下部に、前記取付用穴52に挿通したビス53で取付けられ、その一端部が本体部41の下部と略連続していると共に、内側板24との間に下空間部54を形成している。この下横空間部54は上下に開口している。
前記第2部材50は巻取部11の下方に位置している。
【0020】
前記第3部材60は図3と図4に示すように、第1部材40の一端部と第2部材50の他端部との間に取付けられ、この第3部材60が前述の一部分23cで、前面板22と対向している。
この第3部材60は図7に示すように、本体部61と、その一端部に一体的に設けた仮取付部62と、本体部61の他端部に一体的に設けた取付部63を備えている。
前記本体部61は表面板64と外周面板65で断面ほぼ鉤形状で、円孤状の外周面61aと円孤形状の内周面61bを有する。
前記仮取付部62は、本体部61の表面板64の一端面と連続したほぼ円形の板状形状で、前記第1部材40の本体部41における一端面41c寄りに形成した仮取付凹部、例えば凹陥部66に嵌合する形状である。
前記取付部63は本体部61の外周面板65の他端部と一体的に連続した板状で、取付用穴67を有する。
【0021】
前記第3部材60は図4に示すように、仮取付部62を第1部材40の凹陥部66に嵌合して仮取付けられる。
これによって、本体部61の内周面61bが第1部材40の円孤状突部42に当接すると共に、取付部63が内側板24の取付片68に接する。
取付部63の取付用穴67からビス69を前記取付片68に螺合して取付けられる。

また、第3部材60と第1部材40の円孤状突出部41と内側板24との間に空間部70を形成し、この空間部70が前記上空間部49aに連続し、かつ下横空間部54と間隔を置いて対向する。
そして、前記上空間部49a、下空間部49a、下空間部54、空間部70で前述の電線挿通空間部23bを形成し、各本体部41,61の表面と第2部材50の表面が面一にほぼ連続し、前述のシャッターカーテンのガイド面23aを形成する。
【0023】
前記第2部材50で形成された下空間部54は図3に示すようにガイドレール5の上端部と対向し、第2電線36はその下空間部54からガイドレール5内に挿通されて前述のテープスイッチに接続される。
【0024】
前記シャッターカーテン横ずれ防止部材は一体リング形状としても良いし、第1部材40と第2部材50を一体としても良い。
【0025】
【発明の効果】
請求項1に係る発明によれば、シャッターカーテンの巻き取り・繰り出し時にシャッターカーテン横ずれ防止部材のガイド面に接触することで、シャッターカーテンの横ずれが防止される。
また、シャッターケースの側面板の内面とシャッターカーテン横ずれ防止部材との間に電線挿通空間部が形成され、この電線挿通空間部に電線が配設されているので、シャッターカーテンの巻き取り・繰り出し時にシャッターカーテンと電線が干渉することがない。
【0026】
また、シャッターケースの前面板を開放した状態でシャッターカーテン横ずれ防止部材の一部分を取り外しすることで、コネクタ部分が外部に露出する。
よって、シャッターケースの開口部から電線を接続することができる。例えば、サッシ枠の上部にシャッターケースを取付けた状態で、縦枠側に設けたテープスイッチに接続した電線をシャッターケース内の電線に接続できる。
【0027】
また、前述の一部分を取付けることでコネクタ部分がカバーされるので、そのコネクタ部分に直接雨水などがかかることが防止される。
しかも、前述のような電線の接続作業時にシャッターカーテンは邪魔にならないので、そのシャッターカーテンを巻き取った状態で接続作業できる。
