Description

【0001】
【発明の属する技術分野】
本発明は、開閉体をガイドレールによって開閉方向へ案内するようにした開閉装置、例えばオーバーヘッドドアを含むシャッター装置、ロールスクリーン装置等の開閉装置のガイドレール構造に関に関するものである。
【0002】
【従来の技術】
従来、この種の発明には、開閉体の幅方向の端部を案内凹部に挿入させて開閉方向へ案内するガイドレールを具備し、前記開閉体の端部に突設された鍵バー(ラッチバー等と呼称される場合もある)を、前記開閉体の閉鎖時に前記ガイドレール内に係合させることで、前記開閉体を外部から開放できないようにする機構がある(例えば、特許文献1参照。)。
特に、特許文献1に記載された従来技術は、開閉体が閉鎖された際に自動的に施錠され、巻取り操作等による開閉体の開放動作に伴って自動的に開錠される機構であり、防犯性に優れている上、施錠及び開錠の際の操作性にも秀でた発明である。
【0003】
しかしながら、上記従来技術のように、開閉体の端部をガイドレールにより開閉体方向へ案内するようにした構成によれば、図6に示すように、仮に閉鎖状態にある開閉体110における幅方向の中央側に故意に治具等が掛けられ、該中央側が強引に開閉体厚さ方向における内外何れかの方向(図示例によれば上方又は下方)へ引っ張られると、開閉体110が略弓状に撓み(図6(b)参照)、該開閉体110の幅方向の端部がガイドレール120の案内凹部121から抜き出されて(図6(c)参照)、開閉体110が不適切に開放されるおそれがある。なお、特許文献1に示すように開閉体の幅方向の端部に鍵バーを突設した発明では、該鍵バーがガイドレール内に比較的深く挿入されるため、上記のようにして開閉体の端部の鍵バーをガイドレール内から抜き出すことは困難であったが、一層防犯性を向上することが好ましい。

【発明が解決しようとする課題】
本発明は上記従来事情に鑑みてなされたものであり、その課題とする処は、開閉体が厚さ方向へ引き出されて不適切に開放されてしまうのを防止することで、防犯性を向上した開閉装置のガイドレール構造を提供することにある。
【0006】
【課題を解決するための手段】
上記課題を解決するために第一の発明は、開閉体の幅方向の端部をガイドレールの案内凹部に挿入させて開閉方向へ案内する開閉装置のガイドレール構造において、前記ガイドレールは、前記案内凹部に対して開閉体厚さ方向へ並ぶ位置に、補助凹部を備え、該補助凹部は、前記案内凹部から開閉体厚さ方向へ外れた際の前記開閉体を、開閉体幅方向へ挿入可能なように設けられていることを特徴とする。
【0007】
ここで、本発明のガイドレール構造が適用される開閉装置は、開閉体の開閉動作により空間を仕切ったり開放したりする装置を意味し、この開閉装置には、開閉体が開動作のみを行う態様や、開閉体が閉動作のみを行う態様、開閉体が開動作と閉動作との双方を行う態様等を含む。
尚、上記開閉体の開閉方向は、略垂直方向とするのが好ましく、更には閉鎖方向が下降方向であることがより好ましいが、略水平方向あるいは斜め方向等とすることも可能である。
【0008】
また、上記開閉体は、複数のスラットやパイプを開閉方向へ連設してなる開閉体や、単数もしくは複数連設したパネルからなる開閉体、シート状物やネット状物からなる開閉体、あるいはスラット、パネル、パイプ、シート状物、ネット状物等を適宜に組み合わせてなる開閉体等、何れの態様であってもよい。
【0009】
また、上記「開閉方向」又は「開閉体開閉方向」とは、上記開閉体が開閉動作する方向であって、開閉体の幅方向や厚さ方向でない方向を意味し、以下に記載される同様の表現の箇所も同じ意味とする。
また、上記「開閉体幅方向」又は「開閉体の幅方向」とは、上記開閉体の開閉方向と略直交する方向であって、上記開閉体の厚さ方向ではない方向を意味し、以下に記載される同様の表現の箇所も同じ意味とする。
【0010】
上記ガイドレールは、上記開閉体の幅方向の端部側を上記案内凹部に挿入させて、上記案内凹部により開閉方向へ案内する部材であって、且つ上記案内凹部を開閉体開閉方向へ長尺状に設けている部材である。
また、このガイドレールには、開閉体幅方向に上記開閉体が複数配設され、これら開閉体の内の隣り合う開閉体の間に配設されて、これら隣り合う開閉体の双方を開閉方向へ案内するもの、例えば所謂中柱タイプのガイドレール等も含む。また、上記ガイドレールには、上記ガイドレールの構成にガイドレールとしての機能以外の機能を有する構成を付加したもの、例えば、上記ガイドレールとしての構成とサッシ枠としての構成とを一体的に備えている構成等も含む。
【0011】
また、上記案内凹部は、開閉体の幅方向の端部を挿入させて開閉方向へ案内するように、開閉体開閉方向へ連続して設けられた部位である。
【0012】
また、上記補助凹部は、上記開閉体が上記案内凹部から開閉体厚さ方向へ外れた際に、その外れた開閉体の幅方向の端部を開閉体幅方向へ挿入可能なように形成された断面略凹状の部位であり、この補助凹部は、上記案内凹部に対して開閉体厚さ方向へ並ぶように配置されている。
そして、この補助凹部には、ガイドレールの開閉体開閉方向の略全長に設けられた態様や、ガイドレールの開閉体開閉方向の範囲に部分的に設けられた態様等を含む。
また、この補助凹部の開閉体厚さ方向の配置については、該補助凹部と上記案内凹部とが開閉体厚さ方向へ並ぶように配置されていればよく、例えば、該補助凹部を上記案内凹部に対して開閉体厚さ方向へ隣接するように配置した態様や、該補助凹部と上記案内凹部との間にその他の構成を介在させて、該補助凹部と上記案内凹部とが開閉体厚さ方向へ並ぶように配置した態様等であってもよい。
また、この補助凹部と上記案内凹部とは、それぞれ独立した部材として形成されて開閉体厚さ方向に並ぶように配設されていてもよいし、一体の部材として形成されていてもよい。
また、この補助凹部と上記案内凹部とを開閉体厚さ方向へ配置した構成は、これら双方の凹部を仕切る部材が双方の凹部の共通部材となるようにした態様、より具体的には補助凹部と案内凹部とにより例えば断面略E字状の一体形状となるようにした態様でもよいし、これら双方の凹部を仕切る部材が補助凹部側の部材と案内凹部側の部材とからなる複合部材となるようにした態様であってもよい。
また、この補助凹部は、上記案内凹部の開閉体厚さ方向の片側のみに並ぶように配置されていてもよいし、上記案内凹部の開閉体厚さ方向の両側に並ぶように配置されていてもよい。
【0013】
また、この補助凹部は、ガイドレールの開閉体開閉方向の範囲に部分的に設けられた場合、その開閉体開閉方向の位置が限定されるものではないが、閉鎖状態において開閉体閉鎖方向の端部側の隙間に故意に治具等が挿入されて開閉体が厚さ方向の内外何れかの方向へ引っ張られるのを効果的に防止できるように、開閉体閉鎖方向の端部側に配置するのが好ましい。
また、施錠機構を備えた構成とした場合には、上記補助凹部を、施錠機構に対応する開閉体開閉方向の位置に配置するのが好ましい。
【0014】
なお、上記案内凹部と上記補助凹部のそれぞれの断面形状は、開閉体の幅方向の端部を挿入可能な凹状であればよく、具体例としては、断面略コの字状や、断面略C字状、断面略U字状、断面略凹字状、断面略J字状等が挙げられる。
【0015】
また、第二の発明では、上記補助凹部を、上記ガイドレールにおける少なくとも開閉体閉鎖方向の端部側に配設したことを特徴とする。
【0016】
また、第三の発明では、上記補助凹部を構成する開閉体厚さ方向の両縁部の内、上記案内凹部側と逆側の縁部を、上記案内凹部を構成する上記補助凹部側の縁部よりも、開閉体幅方向中央側へ突出させていることを特徴とする。
ここで、「上記補助凹部を構成する開閉体厚さ方向の両縁部の内、上記案内凹部側と逆側の縁部」とは、より詳細に説明すれば、上記補助凹部を構成するように開閉体厚さ方向に所定間隔をおいて配設された一方側の部位と他方側の部位との内、上記案内凹部側でない方の部位について、この部位における開閉体幅方向中央側の縁部分を意味する。
また、「上記案内凹部を構成する上記補助凹部側の縁部」とは、より詳細に説明すれば、上記案内凹部を構成するように開閉体厚さ方向に所定間隔をおいて配設された一方側の部位と他方側の部位との内、上記補助凹部側の部位について、この部位における開閉体幅方向中央側の縁部分を意味する。
なお、上記開閉体幅方向中央側とは、上記開閉体における幅方向の中央側を意味する。
【0017】
また、第四の発明は、上記補助凹部は、上記案内凹部に隣接して、上記案内凹部の開閉体開閉方向の略全長にわたる範囲に設けられていることを特徴とする。ここで、「上記補助凹部は、上記案内凹部に隣接して」とは、上記補助凹部と上記案内凹部とが開閉体厚さ方向において隣合わせに並んでいることを意味する。
【0018】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。
本実施の形態による一例は、住宅やビル、倉庫、工場、車両の荷台等の構築・構造物における開口部分や内部に配設され、前記開口部分を開閉したり、躯体内部の空間を仕切ったり開放したりする所謂シャッター装置におけるガイドレール構造、特に窓用シャッター装置の防犯構造として好適な開閉装置のガイドレール構造として説明する。
【0019】
この開閉装置のガイドレール構造A1は、開閉装置A(図3参照)における各ガイドレール40に具備されている。
【0020】
開閉装置Aは、開閉動作する開閉体10と、該開閉体10用の巻取り装置21を内在する収納ケース20と、該開閉体10の下端を当接させる下枠30と、該開閉体10をその左右の端部側で開閉方向へ案内する左右のガイドレール40,40とを具備してなり、建築物等の躯体側の窓枠や、該窓枠の外周の躯体壁面等に固定される(図3参照)。
【0021】
開閉体10は、横長略矩形状の金属板を曲げ加工してなる所謂スラットを、上下に隣接する該スラット間で折曲げられるように複数連接するとともに、これらスラットにおける閉鎖方向側(図示例によれば下端側)の端部に、下枠30に当接させるための座板部材11を接続している。
【0022】
座板部材11は、開閉体10の幅方向に沿う長尺状に形成されるとともに、上記スラットと比較して開閉体幅方向に撓み難い断面形状、例えば断面略矩形状や断面略逆T字状に形成され、複数の上記スラットにおける閉鎖方向の端部に、溶接やねじ止め、リベット止め、嵌合等の固定手段により接続固定されている。
尚、当業者間においては、この座板部材11を、座板、幅木、水切り等と呼称する場合もある。
【0023】
前記座板部材11の内部には、該座板部材11の両端各々から鍵バー11a(図1参照)を出没させる施錠機構が備えられている。この施錠機構は、開閉体10が閉鎖された際に、座板部材11の各端部から前記鍵バー11aをガイドレール40内へ向けて突出し、また開錠操作された際に、前記鍵バー11aを座板部材11の各端部内へ没入させる機構である。
【0024】
収納ケース20は、開閉体10の幅方向にわたる略長尺箱状を呈し、少なくとも下面側に開閉体10を出没させるための開口部(図示せず)を形成し、内部には、開閉体10を巻取ったり繰出したりする巻取り軸を軸支した巻取り装置21を具備している(図3参照)。この巻取り装置21は、巻取り動作と繰出し動作との内の一方を電動とし他方を手動とした態様や、双方の動作とも手動または電動とした態様、前記一方の動作をスプリング等の付勢力により行わせるようにした態様等、何れの態様であってもよい。
【0025】
下枠30は、上面31を外方へ向かって下り勾配状に形成した平面視略横長板状の部材であり、その上面31における長手方向の両端側各々に、ガイドレール40を略垂直状に立設し、同上面31における左右のガイドレール40,40の間を、閉鎖された際の開閉体10の座板部材11を当接させるための当接面としている。そして、この下枠30は、建築物等の躯体側の下枠(図示せず)上に固定され、開閉体10の表面に吹き付けられる雨水等を、下り勾配状の前記上面31により外部へ排水する。
【0026】
各ガイドレール40は、アルミ合金材料の引抜き成形または押し出し成形、鋼板や他の金属板の曲げ加工等により、収納ケース20と下枠30との間にわたる長尺状に加工された部材である。
【0027】
このガイドレール40は、開閉体10の幅方向の端部に対向する底部43の内面側に、開閉体10の幅方向の端部を挿入して開閉体開閉方向へ案内するための案内凹部41と、該案内凹部41と同方向に開口部を向けた補助凹部42とを略平行に並設している(図1及び図4参照)。
【0028】
前記案内凹部41は、所定間隔をおいて開閉体厚さ方向へ略平行に配設された前記第一片部41a及び前記第二片部41bと、前記底部43とからなる横断面略コ字状を呈する。
なお、図示例によれば、第一片部41aは、開閉体開閉方向における躯体内方側(図4によれば下側)に配置され、第二片部41bは、第一片部41aと所定間隔をおいて躯体外方側(図4によれば上側)に配置される。
また、第一片部41aと第二片部41bの開閉体幅方向の長さは、略同等に設定されている。
【0029】
そして、案内凹部41は、開閉体10に対面する両内面に、緩和部材60を係合するための被係合部40a,40aを形成している。
各被係合部40aは、開閉体10の表面又は裏面へ向かって横断面略C字状に突出し、ガイドレール40における開閉体閉鎖方向の端部(図3によれば下端部)から開閉体開放方向の端部側にわたって連続的に延設されている。
【0030】
そして、各被係合部40aには、開閉体開閉方向にわたって緩和部材60が嵌合されている。
この緩和部材60は、開閉体10が開閉動作中や風圧を受けてばたついた際等に、該開閉体10に当接され弾性変形することで、開閉体10とガイドレール40との直接的な接触を阻止し、開閉体10表裏面の摩擦抵抗や衝突を緩和する部材である。この緩和部材60は、本実施の形態の好ましい一例によれば、開閉体10の表面又は裏面へ向かって突出する部位を、弾性的に撓み可能な刷毛状に形成している。
【0031】
また、案内凹部41内の底部43における開閉体閉鎖方向の端部側(図示例によれば下端側)には、座板部材11の鍵バー11aを係合可能な側面視略三角形状の鍵受部材44が固定されている(図1参照)。
【0032】
次に、補助凹部42について詳細に説明すれば、この補助凹部42は、上記第二片部41bと、該第二片部41bに対して所定間隔を置いて略平行に配置された第三片部42aとを、底部43により連結してなる横断面略凹状を呈し、上記案内凹部41の開閉体開閉方向の略全長にわたる範囲に設けられている。
【0033】
そして、この補助凹部42は、前記第三片部42aを、上記第二片部41bよりも開閉体幅方向に長く形成している。
すなわち、補助凹部42は、第三片部42aの突端側(図4における左端側)の縁部42a1を、上記案内凹部41における第二片部41bの突端側の縁部41b1よりも、開閉体幅方向中央側(図4における左方向)へ寸法x突出させている。
したがって、図2(a)に示すように、左右のガイドレール40,40における補助凹部42,42の縁部42a1,42a1間の寸法w1は、案内凹部41の縁部41b1,41b1間の寸法w2よりも小さくなる。
【0034】
上記寸法xは、一方(図2によれば左側)のガイドレール40の底面43と、他方(図2によれば右側)のガイドレール40における第三片部42aの縁部42a1との間の幅寸法w3が、開閉体10の幅寸法w4よりも小さくなるように設定するのが好ましい。この構成によれば、案内凹部41から引き出された開閉体10が、左右の防犯凹部42,42間で幅方向の一方側へ寄せられたとしても、その他方側の端部を、対応する防犯凹部42から外れ難くすることができる。
【0035】
また、図4に示すように、補助凹部42内の開閉体厚さ方向の間隔y2(換言すれば第二片部41bと第三片部42aとの間の間隔y2)は、開閉体10を挿入可能なように開閉体10の厚みy3よりも大きく、且つ、挿入された場合の開閉体10が開閉体厚さ方向の外方(図4によれば上方)へ引き外れ難いように、案内凹部41内の開閉体厚さ方向の間隔y1(換言すれば第一片部41aと第二片部41bとの間の間隔y1)よりも小さく設定するのが好ましい。
すなわち、補助凹部42は、案内凹部41のように開閉体10を開閉方向へ導く作用を備える必要がないため、開閉体10を挿入可能な程度に間隔y2を小さくして、案内凹部41から外れて挿入された場合の開閉体10を、更に外方へ引き外れることのないように、挿入された場合の開閉体10の表裏面に近接又は接触するように形成されている。
【0036】
次に、上記構成のガイドレール構造A1による作用効果について詳細に説明する。
閉鎖状態にある開閉体10における幅方向の中央側に、例えば治具等が掛けられて、該中央側が強引に開閉体厚さ方向における外方(図2における上方)へ引っ張られた場合、開閉体10は、該中央側を前記外方側へ膨出させるようにして略弓状に撓むことになる。
すると、開閉体10の幅w4(図2(a)参照)が、図2(b)における幅w4’のように狭くなるため、開閉体10の幅方向の一端部又は両端部が、対応する案内凹部41から開閉体厚さ方向の外方へ抜き出され、その抜き出された端部は、略弓状に撓んだ開閉体10が復元する際の復元力により、補助凹部42内に挿入され係合される(図2(c)に示す状態)。
また、閉鎖状態にある開閉体10における幅方向の中央側に、例えば外方(図2における上方)側から風圧を受けると、開閉体10は、その風圧に対抗する反動により、中央側を前記外方側へ膨出させるようにして略弓状に撓み、幅方向の一端部又は両端部が、対応する案内凹部41から開閉体厚さ方向の外方へ抜き出てしまう場合がある。そして、この場合も上記同様に、抜き出てしまった開閉体10の端部は、略弓状に撓んだ開閉体10が復元する際の復元力により、補助凹部42内に挿入され係合される(図2(c)に示す状態)。
この係合状態における開閉体10は、補助凹部42の縁部42a1が案内凹部41の縁部41b1よりも開閉体10の中央側へ突出しているため、更に中央側が外方へ引っ張られたり、同中央側に風圧を受けたりしたとしても、容易に補助凹部42から外れてしまうことがない。
しかも、この係合状態における開閉体10は、図3に示すように、補助凹部42に挿入された部位10aと、案内凹部41内に残された部位10bとの間において、該開閉体10の幅方向の両端部10c,10cを、左右のガイドレール40,40における第二片部41b,41bの縁部41b1,41b間に、挟まれるようにして噛み込ませるため、更なる外方(図3によれば左方)への移動及び開閉体開放方向(図3によれば上方)への移動を妨げられることになる。
したがって、開閉体10を、補助凹部42よりも更に外方側へは抜き出され難く、且つ開放され難い、防犯性の高い状態に維持することができる。
しかも、開閉体10が風圧によりばたつき難い状態となるため、案内凹部41から外れた開閉体10のばたつきによる騒音の発生や、同開閉体10がばたつくことで近くの物等に接触すること等を防止することができる。
よって、本実施の形態のガイドレール構造A1によれば、開閉装置の防犯性及び耐風性を向上することができる。
【0037】
次に、本発明の他例である開閉装置のガイドレール構造A2について説明する。なお、以下の構成において、上述した開閉装置A及び開閉装置のガイドレール構造A1と略同様の箇所については、同一符号を付けることで重複する詳細説明を省略する。
【0038】
図5に示すガイドレール構造A2は、上述したガイドレール40における案内凹部41内面の両被係合部40a,40aに加えて、補助凹部42を構成する第三片部42a内面にも同形状の被係合部42a2を設け、これら被係合部40a,40a,42a2に、補強部材70をわたらせて固定することで、案内凹部41及び補助凹部42に開閉体厚さ方向の拡開力が作用した際に、その拡開力に対抗するようにしている。
【0039】
補強部材70は、鋼材やステンレス材等の曲げ強度の比較的高い金属製部材からなり、略平板状の底部71の片面側に、略片状の係合部72,73,74を一体的に立設してなる。
そして、この補強部材70は、係合部72,73,74を、それぞれ上記被係合部40a,40a,42aに、開閉体閉鎖方向側から挿入させている。
なお、案内凹部41側の被係合部40a,40aの各々は、ガイドレール40における開閉体閉鎖方向の端部側に前記補強部材70を係合し、該補強部材70よりも開閉体開放方向側に、上述した緩和部材60を係合している。
【0040】
このガイドレール構造A2によれば、開閉体10が厚さ方向における外方へ引っ張られること等により、案内凹部41及び補助凹部42に開閉体厚さ方向の拡開力が作用した際、その拡開力によりガイドレール40が変形してしまうのを抑制することができる。
よって、このガイドレール構造A2によれば、案内凹部41や補助凹部42が変形させられことにより、開閉体10が案内凹部41や補助凹部42から抜き出されてしまうのを防止することができる。
【0041】
尚、上記ガイドレール構造A2において、補強部材70は、案内凹部41及び補助凹部42における拡開方向の外力に対抗するように、案内凹部41及び補助凹部42に交差状にわたらせて固定された部材であればよく、その構成や形状は限定されない。
【0042】
また、この補強部材70を案内凹部41及び補助凹部42に固定する手段は、上記態様に限定されるものでなく、例えば、上記補強部材70の係合部72,73,74を、案内凹部41及び案内凹部41の内面や外面、端面等に、溶接や、ねじ止め、リベット止め等により固定した態様であっても構わない。
【0043】
また、補強部材70の開閉体幅方向の位置は、図示例に限定されるものではないが、効果的に上記拡開力を抑制するためには、図示例のように、案内凹部41及び補助凹部42における縁部41b1,42a1寄りに配置されるのが好ましい。
【0044】
また、上記ガイドレール構造A1は、ガイドレール40の被係合部42a2及び補強部材70の係合部74を省いた構成とすることで、案内凹部41のみを補強する構造としたり、補強部材70の係合部72を省いた構成とすることで、補助凹部42のみを補強したりする構造とすることも可能である。
【0045】
【発明の効果】
本発明は、以上説明したように構成されているので、以下に記載されるような作用効果を奏する。
第一の発明によれば、閉鎖状態にある開閉体の幅方向の中央側が開閉体厚さ方向における内外何れかの方向へ引っ張られることで、該開閉体が略弓状に撓み、該開閉体の開閉体幅方向の端部がガイドレールの案内凹部から抜き出されてしまったとしても、その抜き出された端部は、撓んだ状態から元の状態に戻ろうとする該開閉体の復元力により、補助凹部に挿入され係合される。
この係合状態における開閉体は、補助凹部に挿入された部位と、同開閉体における案内凹部内に残された部位との間において、開閉体幅方向の端部を、案内凹部の補助凹部側の縁部に噛み込ませるため、開閉体幅方向への移動及び開閉体開放方向への移動を妨げられることになる。
そのため、開閉体は、更に引っ張られた場合でも補助凹部から抜き出され難く、且つ開放され難い状態となる。
したがって、開閉体が厚さ方向へ引き出されて不適切に開放されてしまうのを防止することで、防犯性を向上した開閉装置のガイドレール構造を提供することができる。
【0046】

A guide rail structure in a so-called shutter device that is opened, particularly, a guide rail structure of an opening / closing device suitable as a security structure of a window shutter device will be described.
[0019]
The guide rail structure A1 of the opening and closing device is provided on each guide rail 40 in the opening and closing device A (see FIG. 3).
[0020]
The opening / closing device A includes an opening / closing body 10 that opens and closes, a storage case 20 in which a winding device 21 for the opening / closing body 10 is provided, a lower frame 30 that abuts a lower end of the opening / closing body 10, And left and right guide rails 40, 40 for guiding the opening and closing directions at the left and right end sides thereof, and are fixed to a window frame on the skeleton side of a building or the like, or to a frame wall of the outer periphery of the window frame. (See FIG. 3).

A seat plate member 11 for making contact with the lower frame 30 is connected to an end (according to the lower end).
[0022]
The seat plate member 11 is formed in an elongated shape along the width direction of the opening / closing body 10 and has a cross-sectional shape that is less likely to bend in the opening / closing body width direction than the slat, for example, a substantially rectangular cross-section or a substantially inverted T-shaped cross-section. The slats are connected and fixed to ends of the plurality of slats in the closing direction by fixing means such as welding, screwing, riveting, and fitting.
In addition, among those skilled in the art, the seat plate member 11 may be referred to as a seat plate, a baseboard, a drainer, or the like.
[0023]
Inside the seat plate member 11, there is provided a locking mechanism that allows a key bar 11 a (see FIG. 1) to protrude and retract from both ends of the seat plate member 11. The locking mechanism projects the key bar 11a from each end of the seat plate member 11 into the guide rail 40 when the opening / closing body 10 is closed. This is a mechanism for immersing 11 a into each end of the seat plate member 11.
[0024]

Is provided with a winding device 21 which supports a winding shaft for winding and unwinding (see FIG. 3). The winding device 21 has a mode in which one of the winding operation and the feeding operation is electrically operated and the other is manually operated, an operation in which both operations are manually or electrically operated, and an operation in which the one operation is performed by an urging force such as a spring. Or any other mode such as the mode performed by
[0025]
The lower frame 30 is a substantially horizontally long plate-like member in a plan view in which the upper surface 31 is formed in a downwardly sloped shape toward the outside, and the guide rails 40 are substantially vertically formed on both ends of the upper surface 31 in the longitudinal direction. An upright surface is provided between the left and right guide rails 40 on the upper surface 31 as a contact surface for contacting the seat plate member 11 of the opening / closing body 10 when closed. The lower frame 30 is fixed on a lower frame (not shown) on the skeleton side of a building or the like, and drains rainwater or the like sprayed on the surface of the opening / closing body 10 to the outside by the downwardly sloped upper surface 31. I do.
[0026]
Each of the guide rails 40 is an elongated member that extends between the storage case 20 and the lower frame 30 by, for example, drawing or extruding an aluminum alloy material, or bending a steel plate or another metal plate.
[0027]
The guide rail 40 has a guide recess 41 for inserting the widthwise end of the opening / closing body 10 into the opening / closing body opening / closing direction on the inner surface side of the bottom 43 facing the widthwise end of the opening / closing body 10. A guide recess 41 and an auxiliary recess 42 having an opening directed in the same direction as the guide recess 41 are arranged substantially in parallel (see FIGS. 1 and 4).
[0028]
The guide recess 41 has a substantially U-shaped cross section including the first piece 41a and the second piece 41b, which are disposed substantially parallel to the thickness direction of the opening and closing body at a predetermined interval, and the bottom 43. Take the shape.
According to the illustrated example, the first piece 41a is disposed on the inner side of the skeleton in the opening / closing body opening / closing direction (the lower side in FIG. 4), and the second piece 41b is connected to the first piece 41a. It is arranged on the outer side of the skeleton (upper side according to FIG. 4) at a predetermined interval.
The lengths of the first piece 41a and the second piece 41b in the opening / closing body width direction are set to be substantially equal.
[0029]
The guide recess 41 has engaged portions 40 a, 40 a for engaging the relief member 60 on both inner surfaces facing the opening / closing body 10.
Each engaged portion 40a protrudes in a substantially C-shaped cross section toward the front surface or the back surface of the opening / closing body 10, and is opened / closed from the end (the lower end in FIG. 3) of the guide rail 40 in the closing direction of the opening / closing body. It extends continuously over the end in the opening direction.
[0030]
The relaxing member 60 is fitted to each engaged portion 40a in the opening and closing direction of the opening and closing body.
The relaxation member 60 is brought into contact with the opening / closing body 10 and elastically deforms when the opening / closing body 10 is opened and closed or when it flaps due to wind pressure, so that the opening / closing body 10 and the guide rail 40 are directly connected to each other. It is a member that prevents a temporary contact and reduces frictional resistance and collision between the front and back surfaces of the opening and closing body 10. According to a preferred example of the present embodiment, the relief member 60 has a portion projecting toward the front surface or the back surface of the opening / closing body 10 formed in a brush shape that can be elastically bent.
[0031]
A substantially triangular key in a side view that can be engaged with the key bar 11a of the seat plate member 11 is provided at an end (lower end in the illustrated example) of the bottom 43 in the guide recess 41 in the opening / closing body closing direction. The receiving member 44 is fixed (see FIG. 1).
[0032]
Next, the auxiliary concave portion 42 will be described in detail. The auxiliary concave portion 42 is formed of a third piece 41b and a third piece arranged substantially parallel to the second piece 41b at a predetermined interval. The guide recess 41 has a substantially concave shape in cross section formed by connecting the portion 42a to the bottom 43, and is provided in a range over substantially the entire length of the guide recess 41 in the opening / closing body opening / closing direction.
[0033]
The auxiliary recess 42 is formed such that the third piece 42a is longer in the width direction of the opening / closing body than the second piece 41b.
That is, the auxiliary concave portion 42 is configured such that the edge 42a1 on the protruding end side (the left end side in FIG. 4) of the third piece portion 42a is larger than the edge 41b1 on the protruding end side of the second piece portion 41b in the guide concave portion 41. It protrudes by a dimension x toward the center in the width direction (to the left in FIG. 4).
Therefore, as shown in FIG. 2A, the dimension w1 between the edges 42a1 and 42a1 of the auxiliary recesses 42 and 42 in the left and right guide rails 40 and 40 is the dimension w2 between the edges 41b1 and 41b1 of the guide recess 41. Smaller than.
[0034]
The dimension x is between the bottom surface 43 of the one (left side in FIG. 2) guide rail 40 and the edge 42a1 of the third piece portion 42a in the other (right side in FIG. 2) guide rail 40. It is preferable that the width dimension w3 is set to be smaller than the width dimension w4 of the opening / closing body 10. According to this configuration, even if the opening / closing body 10 pulled out from the guide concave portion 41 is moved to one side in the width direction between the left and right security concave portions 42, 42, the end on the other side is brought into a corresponding security position. It is possible to make it difficult to come off from the concave portion 42.
[0035]
As shown in FIG. 4, the gap y2 in the opening / closing body thickness direction in the auxiliary concave portion 42 (in other words, the gap y2 between the second piece 41b and the third piece 42a) is equal to the opening / closing body 10. The guide is provided so that it is larger than the thickness y3 of the opening / closing body 10 so that the opening / closing body 10 can be inserted, and that the opening / closing body 10 when inserted is hard to be pulled outward (upward in FIG. 4) in the thickness direction of the opening / closing body. It is preferable that the distance y1 be smaller than the distance y1 in the opening / closing body thickness direction in the concave portion 41 (in other words, the distance y1 between the first piece 41a and the second piece 41b).
That is, since the auxiliary recess 42 does not need to have the function of guiding the opening and closing body 10 in the opening and closing direction unlike the guide recess 41, the gap y2 is made small enough to allow the opening and closing body 10 to be inserted. The opening / closing body 10 when inserted is formed so as to approach or contact the front and back surfaces of the opening / closing body 10 when inserted so as not to be pulled out further.
[0036]
Next, the operation and effect of the guide rail structure A1 having the above configuration will be described in detail.
For example, a jig or the like is hung on the center side in the width direction of the opening / closing body 10 in the closed state, and the center side is forcibly pulled outward (upward in FIG. 2) in the opening / closing body thickness direction. The body 10 bends in a substantially arcuate shape so that the center side bulges outward.
Then, the width w4 of the opening / closing body 10 (see FIG. 2A) becomes narrow like the width w4 ′ in FIG. 2B, so that one end or both ends in the width direction of the opening / closing body 10 correspond. It is withdrawn from the guide recess 41 outward in the thickness direction of the opening / closing body, and the extracted end portion is inserted into the auxiliary recess 42 by a restoring force when the opening / closing body 10 bent in a substantially arc shape is restored. It is inserted and engaged (the state shown in FIG. 2C).
Further, when a wind pressure is received from the outer side (upper side in FIG. 2) of the opening / closing body 10 in the closed state in the width direction, for example, the opening / closing body 10 is moved to the center side by the reaction against the wind pressure. It may be bent in a substantially bow shape so as to bulge outward, and one end or both ends in the width direction may be pulled out from the corresponding guide recess 41 outward in the thickness direction of the opening / closing body. In this case as well, the end of the extracted opening / closing body 10 is inserted into the auxiliary recess 42 by the restoring force when the opening / closing body 10 bent in a substantially arc shape is restored. (The state shown in FIG. 2C).
In the opening / closing body 10 in this engaged state, the edge 42a1 of the auxiliary recess 42 protrudes toward the center of the opening / closing body 10 more than the edge 41b1 of the guide recess 41. Even if wind pressure is applied to the center side, it does not easily come off from the auxiliary recess 42.
Further, as shown in FIG. 3, the opening / closing body 10 in this engaged state is positioned between the portion 10a inserted into the auxiliary recess 42 and the portion 10b left in the guide recess 41. In order to make the both ends 10c, 10c in the width direction bite between the edges 41b1, 41b of the second pieces 41b, 41b in the left and right guide rails 40, 40, a further outward (see FIG. 3, the movement to the left) and the movement in the opening / closing body opening direction (upward in FIG. 3) are hindered.
Therefore, the opening / closing body 10 can be maintained in a state in which it is difficult to be pulled out more outward than the auxiliary concave portion 42 and is hard to be opened, and has a high security.
Moreover, since the opening / closing body 10 is hardly fluttered by the wind pressure, generation of noise due to the fluttering of the opening / closing body 10 coming off the guide recess 41 and contact of nearby objects or the like due to the fluttering of the opening / closing body 10 are prevented. Can be prevented.
Therefore, according to the guide rail structure A1 of the present embodiment, it is possible to improve the security and wind resistance of the opening and closing device.
[0037]
Next, a guide rail structure A2 of the opening / closing device according to another example of the present invention will be described. In the following configuration, the same reference numerals are given to the same portions as the above-described opening / closing device A and the guide rail structure A1 of the opening / closing device, and overlapping detailed description will be omitted.
[0038]
The guide rail structure A2 shown in FIG. 5 has the same shape on the inner surface of the third piece portion 42a forming the auxiliary recess 42 in addition to the both engaged portions 40a, 40a on the inner surface of the guide recess 41 of the guide rail 40 described above. By providing the engaged portion 42a2 and fixing the reinforcing member 70 to the engaged portions 40a, 40a, 42a2, an expanding force in the opening / closing body thickness direction acts on the guide concave portion 41 and the auxiliary concave portion 42. When it does, it tries to oppose the spreading force.
[0039]
The reinforcing member 70 is made of a metal member having a relatively high bending strength, such as a steel material or a stainless steel material, and has a substantially flat engagement portion 72, 73, 74 integrally formed on one side of a substantially flat bottom 71. Stand up.
The reinforcing member 70 has the engaging portions 72, 73, 74 inserted into the engaged portions 40a, 40a, 42a, respectively, from the opening / closing body closing direction.
Each of the engaged portions 40a, 40a on the guide concave portion 41 engages the reinforcing member 70 at the end of the guide rail 40 in the opening / closing body closing direction, and the opening / closing body opening direction is higher than the reinforcing member 70. On the side, the above-described relaxation member 60 is engaged.
[0040]
According to the guide rail structure A2, when the opening / closing body 10 is pulled outward in the thickness direction and the like, when the expanding force in the opening / closing body thickness direction acts on the guide concave portion 41 and the auxiliary concave portion 42, the expansion is performed. The deformation of the guide rail 40 due to the opening force can be suppressed.
Therefore, according to the guide rail structure A2, it is possible to prevent the opening and closing body 10 from being pulled out of the guide recess 41 and the auxiliary recess 42 due to the deformation of the guide recess 41 and the auxiliary recess 42.
[0041]
In the guide rail structure A2, the reinforcing member 70 is fixed to the guide concave portion 41 and the auxiliary concave portion 42 so as to cross the guide concave portion 41 and the auxiliary concave portion 42 so as to oppose an external force in the expanding direction in the guide concave portion 41 and the auxiliary concave portion 42. The configuration and shape are not limited.
[0042]
The means for fixing the reinforcing member 70 to the guide concave portion 41 and the auxiliary concave portion 42 is not limited to the above embodiment. For example, the engaging portions 72, 73, 74 of the reinforcing member 70 may be fixed to the guide concave portion 41. Alternatively, the guide recess 41 may be fixed to the inner surface, outer surface, end surface, or the like by welding, screwing, riveting, or the like.
[0043]
Further, the position of the reinforcing member 70 in the opening / closing body width direction is not limited to the illustrated example, but in order to effectively suppress the expanding force, as in the illustrated example, the guide recess 41 and the auxiliary It is preferable to be arranged near the edges 41b1 and 42a1 in the recess 42.
[0044]
Further, the guide rail structure A1 has a structure in which the engaged portion 42a2 of the guide rail 40 and the engaging portion 74 of the reinforcing member 70 are omitted, so that only the guide recess 41 is reinforced, or the reinforcing member 70 By omitting the engaging portion 72, it is possible to reinforce only the auxiliary recess 42.
[0045]
【The invention's effect】
The present invention is configured as described above, and has the following functions and effects.
According to the first invention, the open / close body is bent in a substantially arcuate shape by pulling the central side in the width direction of the open / close body in the closed state in either the inside or outside direction in the thickness direction of the open / close body. Even if the end in the width direction of the opening / closing body is pulled out of the guide recess of the guide rail, the extracted end is restored to the original state from the bent state. The force is inserted into and engaged with the auxiliary recess.
The opening / closing body in this engaged state, between the part inserted in the auxiliary recess and the part of the opening / closing body left in the guide recess, closes the end in the opening / closing body width direction to the auxiliary recess side of the guide recess. Therefore, movement in the opening / closing body width direction and movement in the opening / closing body opening direction are hindered.
Therefore, even if the opening / closing body is further pulled, it is difficult for the opening / closing body to be pulled out from the auxiliary concave portion and to be opened.
Therefore, it is possible to provide a guide rail structure of an opening and closing device with improved security by preventing the opening and closing body from being pulled out in the thickness direction and being inappropriately opened.

Furthermore, according to the second invention, since the auxiliary recess is provided on the end side in the closing direction of the opening / closing body, which is a part that is more easily pulled in the opening / closing body thickness direction than other parts, Security can be improved.
[0047]
Further, according to the third aspect, when the widthwise end of the opening / closing body is forcibly pulled out of the guide recess, the end engages the auxiliary recess. Even if the opening / closing body in the engaged state is further forcibly pulled so as to be pulled out from the inside of the auxiliary recess, it is blocked by the edge of the auxiliary recess protruding toward the center in the width direction of the opening / closing body from the edge of the guide recess. Is not easily extracted.
[0048]
Further, according to the fourth aspect, since the auxiliary concave portion is adjacent to the guide concave portion, when the end in the width direction of the opening / closing body is forcibly pulled out of the guide concave portion, it is immediately engaged in the auxiliary concave portion. Will be done.
In addition, since the auxiliary recess is provided in a range extending over substantially the entire length of the guide recess in the opening and closing direction of the opening and closing body, the end in the width direction of the opening and closing body is extracted from the guiding recess at any portion in the opening and closing direction of the opening and closing body. However, the extracted portion is engaged in the auxiliary recess.
