Description

【0001】
【発明の属する技術分野】
本発明は、オーバーヘッドドアを含むシャッター装置、ドア、雨戸を含む引戸、窓、ロールスクリーン、ブラインド、オーニング装置、門扉、ゲート等の開閉装置における締結構造及び締結方法に関し、特にシャッター装置の動作構造に適用するのに好適な開閉装置における締結構造及び締結方法に関するものである。
【0002】
【従来の技術】
従来、この種の締結構造には、開閉動作する開閉体と、該開閉体の幅方向の端部側を開閉方向へ案内するガイドレールと、該開閉体の幅方向の端部側から開閉体厚さ方向へ突出して該開閉体が該ガイドレールから離れる方向へ移動するのを防止する抜止部材とを備え、この抜止部材をリベットにより前記開閉体の幅方向の端部側に締結したものがある。
上記従来技術のように、ガイドレールに対して開閉体を近接または摺接した状態で移動させる構造であって、前記開閉体の幅方向の端部側にリベットが設けられている構造においては、前記リベットの頭部及びカシメ部がガイドレール内へ突出するため、その突出した頭部及びカシメ部がガイドレール内の他の部材に干渉し、摺接音や、当接音、振動等が発生する場合がある。
そこで、例えば特許文献1に記される従来技術によれば、リベット(10)の頭部やカシメ部がガイドレール(5)内の延出部(5A)に干渉しないように、リベット(10)と前記延出部(5A)との距離を、フック部材(7)とガイドレール(5)の閉塞端部(5B)との間の距離よりも長くすることで、リベット(10)が前記延出部(5A)に干渉する前に、フック部材(7)を前記閉塞端部(5B)に摺接させるように工夫している。
【0003】
しかしながら、例えば図10に示す従来技術によれば、リベット110の頭部111が、ガイドレール120内で抜止部材130を係止する係止凸部121に干渉したり、ガイドレール120の開口部に設けられた緩衝部材122に干渉したりすることで、摺接音や、当接音、振動等が発生する場合がある。
また、開閉体140を巻き取り軸に巻き取った際には、リベット110の頭部111やカシメ部112が巻き重ねられることで、巻締音や振動等を発生したり、開閉体140の巻径が大きくなったりする場合もある。
また、上記何れの従来技術においても、リベットの頭部及びカシメ部がガイドレール内のスペースを狭くし、ガイドレール内に緩衝機構や施錠機構等の上記以外の機構を備えたり、ガイドレールの開閉体厚さ方向の全長寸法を小さくしたりするのを困難にしていた。
【0004】

【0005】
【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、締結部材の突出量を小さくすることで、締結部材と他の部材との干渉に起因する摺接音や、当接音、振動等を低減することができる上、締結部材の周囲に有用なスペースを確保したり締結部材の周囲の部材を小型化したりすることができる開閉装置における締結構造及び締結方法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の一手段は、一方の部位に近接または接触する他方の部位を前記一方の部位に対して移動させる構造が備えられた開閉装置における前記両部位の内の一方または双方の部位の締結構造であって、重ね合わせられた二つの部材に締結部材を貫通挿入し、該締結部材の前端係止部と後端係止部との間に前記二つの部材を挟持することで構成され、前記二つの部材の内の少なくとも一方を、変形可能な材料から形成し、前記二つの部材の内の少なくとも一方には、その他方の部材に対向する内部側の部分であって前記締結部材の貫通挿入部位を含む部分に、内部側凹部が形成され、前記二つの部材の内の少なくとも一方は、前記貫通挿入部位を含む範囲を前記内部側凹部内へ変形させた凹状変形部を有し、前記締結部材は、前記前端係止部または前記後端係止部を前記凹状変形部内に没入させていることを特徴とする。
【0007】
ここで、上記手段に係わる締結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、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とすることも可能である。
【0008】
また、「一方の部位に近接または接触する他方の部位を前記一方の部位に対して移動させる構造」の具体例としては、ガイドレールに近接または接触する開閉体を、前記ガイドレールに対して移動させるようにした構造、開閉体やガイドレール、施錠装置を収納するケース等に近接または接触する前記施鍵装置の鍵バーやシリンダー、フック状部材等を、前記開閉体や前記ガイドレールに対して移動させるようにした構造等が挙げられる。

【0010】
なお、前記抜止部材とは、上記開閉体の幅方向の端部側に設けられ、上記ガイドレール内に係合することで、上記開閉体が該ガイドレールから開閉体幅方向において離れる方向へ移動し抜け出てしまうのを阻む部材である。
また、前記ずれ止部材とは、開閉体が複数の開閉体構成部材(例えばスラットやパネル等)を開閉体開閉方向へ複数連設することで構成されている場合に、開閉方向に隣り合う前記開閉体構成部材の内の一方が他方に対して開閉体幅方向へずれてしまうのを防止するように、前記一方の開閉体構成部材と前記他方の開閉体構成部材との双方にわたって係合する部材である。
前記抜止部材と前記ずれ止部材とは、一体的に構成されて上記開閉体に設けられるようにした態様でもよいし、各々別体に構成されて、その各々が上記開閉体に設けられるようにした態様であってもよい。
【0011】
また、上記締結部材とは、上記二つの部材に貫通挿入される軸部と、該軸部の前端側に設けられる上記前端係止部と、該軸部の後端側に設けられる上記後端係止部とを具備し、上記二つの部材に前記軸部を貫通挿入させて、上記前端係止部と上記後端係止部との間を狭めることにより、上記二つの部材を挟持して接合するようにした部材であればよい。
なお、上記前端係止部と上記後端係止部との内の一方または双方は、予め前記軸部の端部側に構成されていてもよいし、上記二つの部材を挟持する際に上記軸部の端部側に構成されるものであってもよい。
上記後端係止部を前記軸部の後端側に予め構成するとともに、上記前端係止部を上記二つの部材が挟持される際に上記軸部の端部側に構成するようにした一例としては、上記締結部材をリベットとした態様が挙げられる。このリベットは、上記後端係止部にあたる頭部と、該頭部と一体の軸部とからなり、該軸部の前端側を専用装置により潰すようにしてかしめることで、該前端側に前記軸部よりも外径の大きい上記前端係止部を形成するようにしたものである。
このリベットの種類には、セミチューブラリベット、フルチューブラリベット、ハトメ、打ち込みリベット、ブラインドリベット、その他の中空リベットや中実リベット等、様々な態様があるが、前端係止部と後端係止部との間に上記二つの部材を挟持するようにしたものであれば、何れの態様であっても構わない。
また、上記締結部材の他例としてはボルトとナットが挙げられ、この態様の場合は、ボルトの頭部が上記後端係止部に対応し、ボルトの前端に螺合されるナットが上記前端係止部に対応することになる。
【0012】
また、上記前端係止部と上記後端係止部との双方を、上記二つの部材が挟持される際に上記軸部の端部側に構成するようにした態様としては、上記二つの部材に貫通挿入可能な軸状に構成され、上記二つの部材を挟持する際に、この軸状の部材の前端側と後端側との双方を専用装置によりかしめることで、上記前端係止部及び上記後端係止部を形成するようにした態様や、上記二つの部材に貫通挿入可能な頭部のない軸状のボルトと、該ボルトの両端側に螺合される上記前端係止部及び上記後端係止部(例えばナット等)とから構成され、上記二つの部材を挟持する際に、この軸状のボルトの前端側と後端側との各々に、上記前端係止部と上記後端係止部とを螺合するようにした態様等が挙げられる。
【0013】
また、上記締結部材は、上記前端係止部と上記後端係止部との間で上記二つの部材を挟持するようにした構成であれば、上記前端係止部と上記後端係止部との間に、例えばワッシャー等の他の部材を介在していてもよい。
また、上記二つの部材の間には、上記内部側凹部が確保されるのであれば、他の部材を介在していても構わない。
【0014】
また、上記変形可能な材料とは、鋼材やアルミニウム合金材、ステンレス材等、塑性変形可能な金属材料であることが好ましいが、ゴムや弾性樹脂材料等の弾性変形可能な材料であってもよい。
【0015】
また、上記内部側凹部とは、上記二つの部材の内の一方または双方に設けられるとともに上記締結部材の貫通挿入部位を含む範囲に設けられる凹部であって、上記凹状変形部を部分的または全体的に没入可能な空間を形成するものであればよい。
そして、この内部側凹部の具体的な形状としては、上記貫通挿入部位を略中央部に配置した略円柱状や、略多角形立方体状、略逆円錐状、略逆角錐状等が挙げられる。
なお、上記内部側凹部を上記二つの部材の内の双方に設ける場合には、二つの上記内部側凹部が向かい合うように配置することで、上記凹状変形部を部分的または全体的に没入可能な空間を、比較的大きく確保することができる。
【0016】
また、上記凹状変形部とは、上記貫通挿入部位を含む範囲を略凹状に変形させることで、上記締結部材の上記前端係止部または後端係止部を少なくとも部分的に没入させるようにした略凹状の部位であればよい。
この凹状変形部は、上記二つの部材の内の一方に形成することで、上記締結部材の上記前端係止部または上記後端係止部を没入させるようにしてもよいし、上記二つの部材の内の双方に形成することで、上記締結部材の上記前端係止部と上記後端係止部とをそれぞれ対応する凹状変形部内に没入させるようにしてもよい。
また、この凹状変形部は、当該締結構造を構成する前に、予めプレス加工等の機械加工により形成されていてもよいが、開閉装置の生産性を良好にする観点より、当該締結構造の製造中に、上記締結部材における前端係止部と後端係止部との間の挟持力によって変形させたものとするのが好ましい。
また、この凹状変形部の深さは、上記締結部材の前端係止部または後端係止部を少なくとも部分的に没入させることで、上記前端係止部または上記後端係止部と他の部材との干渉を軽減するようにした深さであればよいが、好ましくは、前記干渉をより軽減するために、記締結部材の前端係止部または後端係止部を全体的に没入させることが可能な深さに設定される。
【0017】
なお、上記締結部材、上記内部側凹部及び上記凹状変形部の数は限定されるものでなく、単数であっても複数であってもよい。
複数とする場合には、各締結部材と各内部側凹部及び各凹状変形部とが一対一の関係で対応するように、上記締結部材と上記内部側凹部と上記凹状変形部とを夫々複数設けるようにしてもよいし、複数の締結部材を含む範囲に、内部側凹部及び凹状変形部を単数設けるようにしてもよい。
【0018】
また、他の手段では、上記凹状変形部は、上記締結部材における前端係止部と後端係止部との間の挟持力によって上記二つの部材の内の少なくとも一方を変形させることで形成されていることを特徴とする。
ここで、上記挟持力とは、上記締結部材における上記前端係止部と上記後端係止部との間を狭めることにより、その間の部材が挟まれる力を意味する。
例えば、上記締結部材をリベットとした場合、該リベットの前端側を専用装置により潰すようにしてかしめることで、該前端側に上記前端係止部が形成されるとともに、その形成された前端係止部と該リベットの頭部である上記後端係止部との間が狭められて、この間には、上記二つの部材を挟み込む上記挟持力が作用することになる。
また、他例として、上記締結部材をボルトとナットとした場合には、該ボルトの前端側に上記前端係止部であるナットを螺合することにより、その螺合されたナットと該ボルトの頭部である上記後端係止部との間が狭められて、この間には、上記二つの部材を挟み込む上記挟持力が作用することになる。
【0019】
また、他の手段では、上記締結部材がリベットであることを特徴とする。
【0020】
また、他の手段では、上記一方の部位が開閉動作可能な開閉体における幅方向の端部側であり、且つ上記他方の部位が前記開閉体の幅方向の端部側を移動可能に支持するガイドレールであることを特徴とする。
【0021】
なお、「開閉体における幅方向」または「開閉体幅方向」とは、開閉体の開閉方向と略直交する方向であって、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。
また、「開閉体開閉方向」とは、開閉体が開閉する方向であって、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。
【0022】
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、単数もしくは複数のパネルや、シート状物、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。
【0023】
また、上記ガイドレールとは、上記開閉体に近接または接触して、上記開閉体の幅方向の端部側を移動可能に支持するものであればよい。
上記ガイドレールの具体例としては、その支持部分の形状が、断面略コの字状や、断面略C字状、断面略U字状、断面略凹状等の断面形状であって且つ開閉体開閉方向に長尺状に形成されたもの等が挙げられる。
なお、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立設されて、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。
また、上記ガイドレールには、予め固定されていて上記開閉体を開閉方向へ案内する一般的なガイドレールを含むのは勿論のこと、上記開閉体の端部を略完全に固定するものでなければ(例えば、上記開閉体を幅方向へ所定範囲だけ移動可能にするものであれば)、収納状態から閉鎖状態の上記開閉体の幅方向の端部側へ移動し、上記開閉体の撓みやばたつきを抑制する可動型ガイドレールも含む。なお、この可動型ガイドレールには、上記開閉体の開閉動作に伴って送出されたり収納されたりする所謂連動タイプのものや、上記開閉体の開閉動作と独立した動作により送出されたり収納されたりする所謂非連動タイプのもの等があり、上記ガイドレールには、これら双方のタイプのものが含まれる。
【0024】
また、他の手段では、上記重ね合わせられた二つの部材は、上記開閉体を構成する開閉体本体と、この開閉体本体の幅方向の端部側に設けられた抜止部材とであり、該抜止部材は、上記締結部材により前記開閉体本体に接合されるとともに、上記開閉体が上記ガイドレールから離れる方向へ移動した際に、上記ガイドレールに当接するように設けられていることを特徴とする。
ここで、上記抜止部材とは、上述したように、上記開閉体の幅方向の端部側に設けられ、上記ガイドレール内に係合することで、上記開閉体が該ガイドレールから開閉体幅方向において離れる方向へ移動し抜け出てしまうのを阻むものであればよい。
この抜止部材の具体例としては、上記開閉体の幅方向の端部側に、上記開閉体の厚さ方向に突出する凸部材を設け、上記開閉体がガイドレールから離れる方向へ移動した際に、前記凸部部材の突端側を、ガイドレール内に当接させるようにした態様が挙げられる。尚、この態様において、前記凸部材は、前記のようにしてガイドレール内に当接するようにすれば、上記開閉体の表面または裏面のみに設けられていてもよいし、上記開閉体の両面に設けられていてもよい。
また、この抜止部材の他の具体例としては、上記開閉体の幅方向の端部側に、上記開閉体の幅方向へ突出する断面略T字状や、断面略L字状等、先端側が開閉体厚さ方向へ曲がって突出する部材を設け、上記開閉体がガイドレールから離れる方向へ移動した際に、前記部材の突端側を、ガイドレール内に当接させるようにした態様が挙げられる。
【0025】
また、他の手段では、上記前端係止部と上記後端係止部との内の一方は、上記二つの部材の内の一方における上記凹状変形部内に没入され、上記前端係止部と上記後端係止部との内の他方は、上記二つの部材の内の他方における外部側に形成された外部側凹部内に没入されていることを特徴とする。
ここで、上記外部側凹部とは、上記二つの部材の内、上記内部側凹部を設けた部材でない方の部材に設けられるとともに、重ね合わせられた上記二つの部材の外部側に設けられて、上記前端係止部または上記後端係止部を部分的または全体的に没入させる凹部である。
上記外部側凹部の具体的な形状としては、上記貫通挿入部位を略中央部に配置した略円柱状や、略多角形立方体状、略逆円錐状、略逆角錐状等が挙げられる。
【0026】
また、他の手段では、上記締結部材を複数備えるとともに、その夫々の締結部材に対応するように、上記内部側凹部及び上記凹状変形部を複数設けていることを特徴とする。
【0027】
また、他の手段では、上記締結部材を複数備えるとともに、これら複数の締結部材を含む範囲に、上記内部側凹部及び上記凹状変形部を単数設けていることを特徴とする。
【0028】
また、他の手段である締結方法では、上記締結部材の前端係止部と後端係止部との間を狭めることにより、上記二つの部材の内の少なくとも一方を変形させて、上記凹状変形部を形成する工程を含んでいることを特徴とする。
ここで、上記「狭める」とは、例えば、上記締結部材をリベットとした場合には、該リベットの前端側を専用装置により潰すようにしてかしめることで、該前端側に上記前端係止部を形成するとともに、その形成された前端係止部と該リベットの頭部である上記後端係止部との間を狭めることを意味する。
また、例えば、上記締結部材をボルトとナットとした場合には、該ボルトの前端側に上記前端係止部であるナットを螺合することで、その螺合されたナットと該ボルトの頭部である上記後端係止部との間を狭めることを意味する。
【0029】
【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、構築・構造物などの躯体の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際に、ガイドレールに近接または接触する開閉体を、該ガイドレールに対して移動させる所謂シャッター装置において、前記開閉体の幅方向の端部側の締結構造及び締結方法として説明する。
【0030】
この締結構造A1は、開閉体10の幅方向の端部側に配設された構造であり、前記開閉体10の幅方向の端部側を、ガイドレール20の断面略コ字状の部分の開口部20a(図4参照)に挿入した状態で、ガイドレール20内面に沿って該ガイドレール20の長手方向へ移動させるようにした開閉装置に具備されている。
【0031】
開閉体10は、開閉体本体11と、該開閉体本体11の幅方向の端部側に重ね合わせられた抜止部材30とを備えている。
【0032】
開閉体本体11は、略長尺矩形状の塑性変形可能な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回動されるように複数連接してなる。
【0033】
この開閉体本体11の幅方向の端部側には、単数もしくは複数の締結部材40を貫通挿入させるための単数もしくは複数の貫通挿入孔11a(図2参照)が穿設され、この貫通挿入孔11aに挿通される締結部材40によって、後述する前記締結部材40が止着されている。
【0034】
抜止部材30は、略矩形状の金属板を断面略への字状に曲げ加工することで、開閉体本体11の内面に接触される止着片部31と、開閉体本体11よりもガイドレール20底面側(図2乃至5における右側)へ突出し、且つ開閉体厚さ方向へ傾斜状に曲げられた係合片部32とを形成している。
【0035】
止着片部31は、開閉体本体11の内面に重ね合わせ可能な略矩形平板状に形成され、開閉体本体11内面と当接する内部側の面に、開閉体本体11の上記貫通挿入孔11aに連通する貫通挿入孔31a(図2参照)を形成するとともに、該貫通挿入孔31aを含む該貫通挿入孔31aの周囲に、略円筒形の座ぐり加工状に内部側凹部31bを形成している。
また、同止着片部31は、開閉体本体11との当接面でない外部側の面に、前記内部側凹部31b同様の略円筒形の座ぐり加工状に、外部側凹部31cを形成している。
【0036】
前記内部側凹部31bは、締結部材40が締め付けられた際に、開閉体本体11における後述する凹状変形部11bを没入させるとともに、該凹状変形部11bの表側(図3によれば下側)の面に、締結部材40における後述する後端係止部41を没入させた状態で、前記後端係止部41の後端部が開閉体本体11の表側の面よりも突出しないように、深さ寸法が設定されている。
【0037】
また、前記外部側凹部31cは、締結部材40が止着された際に、締結部材40における後述する前端係止部42を、止着片部31の外部側(図3によれば上側)の面よりも突出しないように、深さ寸法が設定されている。この外部側凹部31cの深さ寸法は、本実施の形態の一例によれば、上記内部側凹部31bの深さ寸法よりも浅く設定されている。
【0038】
なお、上記構成の抜止部材30は、開閉体本体11における前記スラット毎に設けられてもよいし、開閉体本体11の開閉方向にわたって所定間隔置きに配設されていてもよい。
【0039】
また、締結部材40は、略トラス頭状もしくは略なべ頭状の後端係止部41と、前端側に略円筒状の中空部を有する軸部40aとからなる金属リベットであり、本実施の形態の好ましい一例によれば、JIS規格等によって規定されるセミチューブラリベットを用いている。
そして、この締結部材40は、上記開閉体本体11及び抜止部材30に貫通挿入され、専用装置x(図2参照)によりカシメられることにより、前記軸部40aの前端側が潰されて、この前端側に、元の軸部40aよりも外径の大きい前端係止部42を形成するようになっている。
【0040】
ガイドレール20は、鋼板や他の金属板の曲げ加工や、アルミ合金材料の引抜き成形または押し出し成形等の加工によって、開閉体10の幅方向の端部を、開閉体開閉方向にわたって囲むように形成された部材であり、開閉体10が閉鎖された際に当接する部位、例えば下枠部材や床面、地面等に立設されている。
このガイドレール20は、更に詳細には、開閉体10の幅方向の端部を囲む部位を、開閉体10を略中央に置いて開閉体厚さ方向の両側に略並行に配置される両側面部21,22、これら両側面部21,22に略直交するように連接された底部23等からなる横断面略コ字状に形成している(図4及び5参照)。
【0041】
そして、このガイドレール20の内部には、両側面部21,22における開口部20a側にガイドレール20の長手方向にわたって長尺状に設けられた緩衝部材20b,20bや、一方の側面部にガイドレール20の長手方向にわたって長尺状に固定された係合部材20c、他方の側面部にガイドレール20の長手方向にわたって長尺状に固定された係合補助部材20d、底部23にガイドレール20の長手方向わたって長尺状に固定された摩擦軽減部材20e等を備えている。
【0042】
前記緩衝部材20b,20bは、弾性材料からなり、開閉体10が開閉動作時の振動や風圧等により厚さ方向へばたついた際等に、開閉体10とガイドレール20内面との当接による衝撃を緩和したり、開閉体10の表裏面とガイドレール20内面との摩擦を軽減したりする。
【0043】
また、係合部材20cは、開閉体10が風圧を受けて撓んだり開閉動作時の振動を受けたり等することに起因して、開閉体10の端部がガイドレール20から離れる方向へ移動し抜けてしまうことがないように、抜止部材30に係合する。
また、係合補助部材20dは、撓んだ際の開閉体10における幅方向の端部に対して開閉体厚さ方向に当接することで、抜止部材30と前記抜止部材30との係合性を良好にし、抜止部材30による抜止効果を向上する。
【0044】
また、摩擦軽減部材20eは、硬質合成樹脂材料からなる略平板状の部材であり、開閉体10が開閉動作時の振動や風圧の影響等に起因して開閉動作中に幅方向へ移動した際等に、開閉体10の幅方向の端部(換言すれば抜止部材30の先端部)が直接底部23に摺接して摺接音を発生するのを防止したり、同端部とガイドレール20との当接音や当接の際の衝撃を緩和したり等する。
【0045】
次に、上記締結構造A1を製造する手順について、詳細に説明する。
先ず、双方の貫通挿入孔11a,31aが連通状になるように、開閉体本体11の内面に、抜止部材30の止着片部31を重ね合わせる。
そして、双方の貫通挿入孔11a,31aに、締結部材40の軸部40aを、後端係止部41が開閉体本体11の表面側(図1によれば下面側)となるように挿入する。
【0046】
そして、専用装置x(図1参照)の受け型部とハンマ部との間に、締結部材40を軸方向に挟み、締結部材40の一端側を前記ハンマ部で叩く。
すると、締結部材40の軸部40a前端側に前端係止部42が形成されるのと略同時に、その形成された前端係止部42と後端係止部41との間が狭められる。
したがって、開閉体本体11は、前端係止部42と後端係止部41との間の挟持力によって、貫通挿入孔11aを略中心にした範囲を、抜止部材30の内部側凹部31bに没入させるようにして変形させ、凹状変形部11bが形成される(図3参照)。
その凹状変形部11bの形成と略同時に、締結部材40の後端係止部41が、凹状変形部11b表側(図3によれば下側)の凹状面に、略全体的に没入される。
【0047】
また、締結部材40の軸部40a前端側が潰されることにより形成された前端係止部42は、抜止部材30の外部側凹部31c内に、略全体的に没入された状態となる。
【0048】
そして、開閉体本体11と抜止部材30とは、締結部材40の後端係止部41と前端係止部42とにより挟持されることで接合される。
【0049】
上記構成の締結構造A1によれば、締結部材40の後端係止部41及び前端係止部42が開閉体10の厚さ方向へ殆ど突出しないため、後端係止部41または前端係止部42と緩衝部材20bとの干渉や、後端係止部41または前端係止部42と係合部材20cとの干渉等を低減することができる(図4及び5参照)。
【0050】
なお、上記締結構造A1によれば、抜止部材30のみに内部側凹部31bを形成したが、開閉体本体11の内部側にも上記内部側凹部31b同様の内部側凹部を形成することで、開閉体本体11が変形して没入される空間を大きくし、後端係止部41の没入量を大きくして、後端係止部41と緩衝部材20bまたは係合部材20cとの干渉を一層低減することも可能である。
【0051】
また、上記締結構造A1によれば、締結部材40の後端係止部41を開閉体本体11の凹状変形部11b内に配置するとともに、同締結部材40の前端係止部42を抜止部材30の外部側凹部31c内に配置したが、その配置関係を逆にして、締結部材40の後端係止部41を抜止部材30の外部側凹部31c内に配置するとともに、同締結部材40の前端係止部42を開閉体本体11の凹状変形部11b内に配置しても構わない。
【0052】
また、上記締結構造A1は、開閉体10を構成する開閉体本体11と、この開閉体本体11の幅方向の端部側に設けられた抜止部材30とを締結部材40により挟持し接合する態様としたが、本発明は、一方の部位に近接または接触する他方の部位を前記一方の部位に対して移動させる構造において、これら両部位の内の一方または双方の部位に設けられることで、上述した干渉を低減する効果を奏するものである。
したがって、本発明によれば、例えば、上記緩衝部材20bを上記締結部材40によりガイドレール20の内面に止着するとともに、その緩衝部材20bを締結部材40の後端係止部41と前端係止部42との間の挟持力により変形させて、上記凹状変形部11bと同様の凹状変形部を形成し、該凹状変形部内に後端係止部41または前端係止部42を没入させるようにした構成としてもよい。
また、本発明によれば、例えば、上記係合部材20cまたは係合補助部材20dを変形可能に構成し、この係合部材20cまたは係合補助部材20dを、上記締結部材40によりガイドレール20の内面に止着するとともに、締結部材40の後端係止部41と前端係止部42との間の挟持力により変形させて、上記凹状変形部11bと同様の凹状変形部を形成し、該凹状変形部内に後端係止部41または前端係止部42を没入させるようにした構成としてもよい。
また、本発明によれば、例えば、上記摩擦軽減部材20eを変形可能に構成し、この摩擦軽減部材20eを、上記締結部材40によりガイドレール20の底部23に止着するとともに、締結部材40の後端係止部41と前端係止部42との間の挟持力により変形させて、上記凹状変形部11bと同様の凹状変形部を形成し、該凹状変形部内に後端係止部41または前端係止部42を没入させるようにした構成としてもよい。
【0053】
次に、本発明に係わる開閉装置における締結構造の他例について説明する。
なお、以下に示す締結構造について、上記締結構造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説明を省略する。
【0054】
図6及び7に示す締結構造A2は、上記締結構造A1に対して、開閉体10を構成している開閉体本体11及び抜止部材30を、開閉体本体12及び抜止部材50に置換した構成となっている。
【0055】
開閉体本体12は、内部に中空部を有するスラット12aを、上下に隣接する該スラット12a,12a間で回動されるように、複数連接してなる。
【0056】
スラット12aは、塑性変形可能な金属板を、断面略枠状に曲げ加工してなり、その上端側には、上方側のスラット12aに係合するためにカール状に形成された係合部12a1が備えられ、その下端側には、下方側のスラット12aの前記係合部12a1によって係合される被係合部12a2が備えられている。
また、スラット12a内の中空部には、必要に応じて、断熱や、振動及び音の抑制等を目的とする発泡材(例えばウレタン発泡材等)が充填される。
【0057】
抜止部材50は、合成樹脂材料により成形され、開閉体本体12の幅方向端部の開口部から該開閉体本体12内へ挿入され止着される挿入止着部51と、前記開口部の縁に当接される鍔部52と、ガイドレール20の底面側へ突出する係合片部53とを具備している。
そして、この抜止部材50は、開閉体本体12を構成する複数のスラット12aに対して、スラット12a一つ置きに配設される。
【0058】
挿入止着部51は、スラット12aに挿入された際に、表裏両面をスラット12aの内面に近接または接触させるように、スラット12aの内面形状に略倣った形状に形成されている。
この挿入止着部51の表裏各面には、上述した締結構造A1の抜止部材30と略同様に、複数の内部側凹部31bが形成されている。そして、表裏の内部側凹部31b,31bは、貫通挿入孔31aにより連通されている。
【0059】
鍔部52は、前記スラット12aの幅方向の端部に接触または近接するとともに、同スラット12aの上下の係合部12a1及び被係合部12a2にわたるように形成されている。
詳細には、この鍔部52は、挿入止着部51よりも上方へ突出する押さえ片部52aと、同挿入止着部51よりも下方へ突出する押さえ片部52bとを備え、上側の押さえ片部52aを、上方側で係合し合う係合部12a1及び被係合部12a2に接触または近接させるとともに、下側の押さえ片部52bを、下方側で係合し合う係合部12a1及び被係合部12a2に接触または近接させる。
したがって、この鍔部52は、前記した押さえ片部52aと係合部12a1及び被係合部12a2との接触または近接、そして押さえ片部52bと係合部12a1及び被係合部12a2との接触または近接により、上下に隣り合うスラット12a,12aの内、一方のスラット12aが他方のスラット12aに対して幅方向へずれてしまうのを抑制する。
【0060】
また、抜止部材50は、ガイドレール20の係合部材20cに係合されるように、突端側の厚さ寸法を開閉体幅方向へ大きくした断面略T字状に形成されている。
また、この抜止部材50は、スラット12aの幅方向の両端部にそれぞれ配設されることで、これら両端部の各々において、開閉体本体12がガイドレール20から離れる方向(図4及び5によれば左方向)へ抜けてしまうのを阻むとともに、上記したように上下に隣り合うスラット12a,12aの内の一方が他方に対して幅方向へずれてしまうのを抑制する。
【0061】
そして、上記構成の抜止部材50は、上記開閉体本体12に挿入止着部51を挿入させて、上記締結構造A1同様に、複数の締結部材40によって開閉体本体12に止着される。
その止着の際、締結部材40の後端係止部41と前端係止部42との間の挟持力により、開閉体本体12は、その表裏両面の各面において、各貫通挿入孔11aを略中心にした範囲を、抜止部材30の内部側凹部31bに没入させるように変形させる。
したがって、締結部材40における後端係止部41の周囲と前端係止部42の周囲とには、それぞれ凹状変形部12bが形成される。
【0062】
なお、図示例の締結構造A2によれば、締結部材40と該締結部材40に対応する内部側凹部31b及び凹状変形部12bを、開閉体開閉方向に三つ並べて設けているが、その数は図示例に限定されるものでなく、単数であってもよいし複数であってもよい。
【0063】
次に、図8及び9に示す締結構造A3について説明する。
この締結構造A3は、上記締結構造A2に対して、抜止部材50を抜止部材60に置換した構成とすることで、複数の締結部材40を含む範囲に、単数の内部側凹部61及び凹状変形部12b’を設けている。
【0064】
抜止部材60は、上述した抜止部材50の挿入止着部51を挿入止着部51’に置換した構成としている。
挿入止着部51’には、抜止部材60を挿通するための複数の貫通挿入孔31a’が形成され、これら複数の貫通挿入孔31a’を含むように、単数の内部側凹部61が形成されている。
【0065】
内部側凹部61は、挿入止着部51’の周縁部62と鍔部52とにより囲まれた凹状の部位である。
前記周縁部62は、挿入止着部51’の外周縁の近傍部位であって且つ鍔部52を除く部位であり、スラット12aの内面へ向かって突出して、スラット12aの内面に対して近接または接触する。
【0066】
上記構成の抜止部材60は、スラット12aに挿入止着部51’を挿入させて、複数の締結部材40によって開閉体本体12に止着される。
その止着の際、各締結部材40の後端係止部41と前端係止部42との間の挟持力により、開閉体本体12は、その一方の面(図9によれば左側の表面)において、内部側凹部61に沿った範囲を、該内部側凹部61内側へ没入させるようにして変形させる。
したがって、複数の後端係止部41を含むようにして、単一の凹状変形部12b’が形成される。
【0067】
この締結構造A3によれば、凹状変形部12b’が該凹状変形部12b’以外の箇所よりもスラット12a内部側へ凹み、その凹状変形部12b’による凹みの中に後端係止部41が配置されるため、ガイドレール20内での後端係止部41による干渉を低減できる上、開閉体10が巻き取られる際における後端係止部41による干渉も低減することができる。
また、スラット12aが断面略弓状を呈し(図9参照)、その凹み側の面(図9によれば右側の裏面)に、締結部材40の前端係止部42が配置されるため、ガイドレール20内での前端係止部42による干渉や、開閉体10が巻き取られた際における前端係止部42による干渉についても低減される。
【0068】
また、予め貫通挿入孔11a及び貫通挿入孔31a’が形成されていない状態で締結構造A3が構成される場合(例えば現場等で締結構造A3が構成される場合等)には、スラット12aに挿入止着部51’が挿入された後に、それらスラット12a及び挿入止着部51’にドリル等の治具を貫挿させる貫通作業が行われ、該貫通作業により、前記貫通挿入孔11a及び前記貫通挿入孔31a’が形成される。
その際、内部側凹部61が、スラット12a内に配置され目視されないが、比較的広い範囲に形成されているため、前記貫通作業は、特に位置あわせ等を意識することなく容易に行われることになる。
【0069】
なお、上記締結構造A3において、スラット12aの材質は、塑性変形可能な金属板であれば限定されるものでないが、特に比較的広い面積の内部側凹部61を形成し易くするためには、曲げ変形し易い金属板材料であることが好ましく、本実施の形態の好ましい一例によれば、比較的薄肉なアルミニウム合金板が用いられている。
【0070】
また、上記構成の締結構造A1,A2,A3では、締結部材40としてセミチューブラリベットを用いているが、この締結部材40は、前記セミチューブラリベットに限定されるものでなく、フルチューブラリベットやその他のリベット、ボルトとナット等であってもよい。
また、締結部材40の他の好ましい態様としては、金属等からなる平面視略コ字状の締結部材(例えば所謂ステープル等)とし、この締結部材の後端部を上記後端係止部とし、同締結部材の両先端側を上記前端係止部とし、そして、この構成の締結部材が略ホッチキス状の専用工具等により止着されるようにしてもよい(図示せず)。
この態様では、上記締結構造A1,A2,A3におけるスラット及び抜止部材の貫通挿入孔(11a,11a’,31a,31a’等)を省き、専用工具等を用いて、平面視略コ字状の前記締結部材を、スラット及び抜止部材に刺し通すようにする。そして、平面視略コ字状の前記締結部材の両先端側が、専用工具等における受け側の金型等に当接されて折り曲げられるようにする。
この態様によれば、前記専用工具等により前記スラットの厚さ方向に挟持力が作用するため、前記スラットは、内部側凹部に対応する部位を該内部側凹部内へ没入させるように変形して、凹状変形部を形成することになる。そして、この凹状変形部内には、前記締結部材の後端係止部や前端係止部等が没入されることになる。
なお、この態様では、前記締結部材を前記スラット及び前記抜止部材に刺し通す必要があるため、前記スラット及び前記抜止部材は、アルミニウム合金等の軟質な金属材料や合成樹脂材料等から比較的薄肉状に形成されるのが好ましい。
【0071】
本実施の形態は、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。
先ずは、締結部材の前端係止部又は後端係止部が凹状変形部内に没入されるため、上記一方の部位に対して上記他方の部位を移動させる際、締結部材の前端係止部又は後端係止部と、上記一方の部位又は上記他方の部位との干渉を低減することができる。
しかも、前端係止部及び後端係止部の突出量が小さくなるため、締結部材の周囲の空間を有効に利用したり、締結部材の周囲の寸法を小さくしたりすることができる。
したがって、締結部材の突出量を小さくすることで、締結部材と他の部材との干渉に起因する摺接音や、当接音、振動等を低減することができる上、締結部材の周囲に有用なスペースを確保したり締結部材の周囲の部材を小型化したりすることができる。
【0072】
更に、他の手段によれば、凹状変形部を締結部材の締付け作業により容易に形成することができ、ひいては、開閉装置の生産性を向上することができる。
【0073】
更に、他の手段によれば、ボルト及びナット等と比較して、リベットである締結部材の止着作業を短時間に行える上、締結部材の緩み等の発生を低減できる。
【0074】
更に、他の手段によれば、開閉体がガイドレールに沿って開閉動作する際に、締結部材が開閉体又はガイドレールに干渉することに起因して、摺接音や、当接音、振動等が発生するのを低減することができる。しかも、締結部材の前端係止部又は後端係止部の突出量が小さくなるため、ガイドレール内に有用なスペースを確保したりガイドレールの開閉体厚さ方向の寸法を小さくしたりすることができる。
【0075】
更に、他の手段によれば、開閉体がガイドレールに沿って開閉動作する際に、開閉体と抜止部材とを接合する締結部材がガイドレールに干渉することに起因して、摺接音や、当接音、振動等が発生するのを低減することができる上、開閉体が巻き取られた場合に発生する巻締音や振動も低減し、巻き取られた開閉体の巻径を小さくすることもできる。しかも、締結部材の前端係止部又は後端係止部の突出量が小さくなるため、ガイドレール内に有用なスペースを確保したりガイドレールの開閉体厚さ方向の寸法を小さくしたりすることができる。
【0076】
更に、他の手段によれば、締結部材における前端係止部と後端係止部との内、その一方が凹状変形部内に没入され、他方が凹部内に没入される。すなわち、双方の締結部材における双方の係止部の突出量が小さくなる。
したがって、締結部材の前後双方の突出量を小さくすることで、締結部材による干渉に起因する摺接音や、当接音、振動等を一層低減することができる上、締結部材の周囲に有用なスペースをより多く確保したり締結部材の周囲の部材を一層小型化したりすることができる。
【0077】
更に、他の手段によれば、締結部材と内部側凹部及び凹状変形部とが一対一に対応するように複数設けられているため、各凹状変形部の面積が比較的小さい。したがって、外観上の体裁を向上することができる上、各締結部材を締め付ける荷重を比較的小さくすることができる。
よって、仮に、上記二つの部材の内、凹状変形部を設けた側の一方の部材が、比較的厚肉な部材である場合や比較的剛性の高い部材である場合であっても、各締結部材の締め付け作業が容易であり、生産性が良好である。
【0078】
また、他の手段によれば、複数の締結部材を含む範囲に内部側凹部及び凹状変形部が単数設けられているため、単数である内部側凹部の面積が比較的大きい。
したがって、締結部材を貫通挿入する位置と、内部側凹部の位置とを合わせる際の位置合わせ作業が比較的容易である。
すなわち、例えば、開閉体と内部側凹部を有する部材とを重ね合わせて、それら双方に締結部材を挿入するための貫通孔を穿設する際、内部側凹部が開閉体と該内部側凹部を有する部材との間に位置して目視し難い場合がある。このような場合でも、本発明によれば、内部側凹部の面積が比較的大きいため、内部側凹部に対応しない箇所に前記貫通孔を形成してしまうというミスを減らすことができる。
【0079】
また、他の手段の締結方法によれば、凹状変形部を締結部材の締付け作業により容易に形成することができ、ひいては、摺接音や、当接音、振動等の発生を低減した開閉装置を、効率よく生産することができる。
