Description
【0001】
【発明の属する技術分野】
本発明は、航空機の操縦室(コックピット)と客室(キャビン)との間に設けられる操縦室ドア(コックピットドア)に関する。
【0002】
【従来の技術】
図12には、航空機の操縦室2と客室4の間に設けられる操縦室ドア1を示し、飛行中にはコックピットドア1は閉鎖状態を保たれ、ドアの開閉はコックピット2側からのみ行われる。
【0003】
【発明が解決しようとする課題】
最近のテロの発生等に対抗するために、コックピットドアの強度向上の必要性が高まり、各種の対策が考えられている。
本発明は、要求される強度を満たすコックピットドアを提供することを目的とする。
【0004】
【課題を解決するための手段】
本発明の航空機の客室と操縦室との間に設けられる操縦室ドアは、ドアの外枠を構成するフレームと、フレームの内部に固定される可撓性を有する積層部材とを備え、積層部材は、外周部に設けられる複数の舌状の取付部を有し、取付部が巻き付けられる金属板製のサッシと、巻き付けられた取付部をサッシに固定する金属製の取付具を備えるものである。
そして、積層部材は、芳香族ポリアミド繊維を布状に加工したシートを多数枚積層一体化した構造を有し、取付部はシートの一部を外周側に延長して形成されるものである。
【0005】
【発明の実施の形態】
図1は、本発明の操縦室ドア(コックピットドア)の正面図、図2は左側面図、図3は右側面図、図4は上面図、図5は図1のA−A矢視図である。
全体を符号1で示すコックピットドアは、ドアパネル10と、ドアパネル10の一方の側端部に取付けられる複数のヒンジ20を有する。
【0006】
ドアパネル10のヒンジとは反対側の側端部には、ラッチ装置30が取付けられる。ラッチ装置30は、ハンドル32とハンドル32により操作されるボルト34を有する。ラッチ装置30は、コックピット2側に取付けられ、コックピット2側からのみ操作される。
【0007】
コックピットドアのキャビン4側にはラッチ装置30に対向して、カバー40が取付けられる。このカバー40内には、キャビンの与圧が導入され、コックピット2側に減圧が発生したときには、キャビン4側との圧力差を検知して、ラッチ装置30を作動し、ハンドル32を開いて、ボルト34をキャッチから解放する機構が装備される。
【0008】
図1のA−A矢視図である図5に示すように、ドアパネル10は、フレーム110と、フレーム110の内側に取付けられるハニカムパネル120を有する。フレーム110の外側には、ヒンジ20が取付けられる。ハニカムパネル120のキャビン4側には化粧シート130が貼付けられる。
ハニカムパネル120に対して全体を符号200で示す積層部材が重ね合わされる。
積層部材200のコックピット2側の面には、表面シート160が貼付けられる。
【0009】
図6は、ドアパネルの内部構造を示す正面図、図7は右側面図、図8は上面図、図9は要部の断面図である。
積層部材200は、芳香族ポリアミド繊維(アラミド繊維)を布状に加工したシートを多数枚積層して一体化したものであって、高い強度を有する。
【0010】
図10は、積層部材200の正面図、図11は上面図である。
積層部材200は可撓性のあるシートを多数枚積層した構造を有し、全体としてもある程度の可撓性を有する。
この積層部材を構成するシートのうち、所定の枚数のシートを外周方向へ延ばして、舌状の取付け部210を備えている。積層部材200には、ラッチ装置を受け入れる切欠部220を設けてある。
【0011】
そこで、この積層部材200の外周部の取付部210を金属の細板でつくられるサッシ300に対して巻き付け、取付部210の外側に固着具310をあて、固着具310をビス等でサッシに固着して、積層部材200の外周部をサッシ300に対して固定する。
このサッシ300に取付けられた積層部材200をドアパネルのフレーム110の内側にビス等で固着することで、ドアパネル10を作成する。
【0012】
【発明の効果】
本発明の操縦室ドア(コックピットドア)は以上のように、軽量で強度の高い芳香族ポリアミド繊維シートを多数枚積層一体化した積層部材を、ドアのフレームに対して強固に固定した構造を有するので操縦席ドアに衝撃等の大きな外力が加えられた場合にも、その衝撃エネルギーを吸収して、ドアの破損を防止することができるものである。
