Description
図1は、第1実施形態に係る鉄道車両1のドア装置10及びその近傍を示す側面図である。図1に示すように、鉄道車両1は、ドア開口部2aが形成された側構体2と、ドア開口部2aを開閉するための両開き式のドア装置10とを備えている。ドア装置10は、互いに近接及び離反してスライド開閉する第1側引戸11及び第2側引戸12と、それら側引戸11,12のそれぞれの戸先に鉛直方向に沿って取り付けられた一対の戸先ゴムである第1弾性部材21及び第2弾性部材22とを備えている。第1及び第2側引戸11,12の上部には、それぞれ滑車3,4が取り付けられ、それら滑車3,4がドア開口部2aの上方に設置されたガイドレール8に案内されている。第1及び第2側引戸11,12の上方には、ブラケット5,6を介して第1及び第2側引戸11,12をスライド開閉するためのドア駆動装置7が設置されている。このドア駆動装置7には、圧縮空気を用いて駆動する空気式と、モータを用いて駆動する電動式とが存在している。また、ドア駆動装置7には、第1及び第2側引戸11,12が閉まるときの抵抗により異物の挟み込みを検知する異常検知装置9が設けられている。なお、ドア駆動装置の配置や側引戸の案内機構等は、種々のものが考えられ、これに限定されるものではない。
図5は、第2実施形態に係る鉄道車両のドア装置110の図2相当の図面である。図5に示すように、第2実施形態では、第1弾性部材121の第1突出壁部125に形成された小溝125dと、第2弾性部材122の第2及び第3突出壁部126,127に形成された小溝126d,127dとが、第1実施形態に比べて幅が狭く数が増えている。具体的には、小溝125d,126d,127dは、そのドアスライド方向の幅がそのドア厚み方向の深さよりも小さくなっている。これにより、第1~第3突出壁部125~127の側面における車外側から室内側に向けた表面距離をより長くすることができ、車外から室内への浸水を良好に防止することができる。なお、第1実施形態と共通する構成については同一符号を付して説明を省略する。
図6は、第3実施形態に係る鉄道車両のドア装置210の図2相当の図面である。図6に示すように、第3実施形態では、第1弾性部材221の第1突出壁部225に形成された小溝225dと、第2弾性部材222の第2及び第3突出壁部226,227に形成された小溝226d,227dとが、短辺と長辺からなる断面V形状であり、ドアの中心線Cを基準にしてドア厚み方向に対称な形状を呈している。なお、小溝225d,226d,227dの短辺と第1~第3突出壁部225~227の外面とのなす角は、小溝225d,226d,227dの長辺と第1~第3突出壁部225~227の外面とのなす角よりも、鋭角である。これにより、小溝225d,226d,227dの短辺部分が水を好適に捕捉することができる。なお、第1実施形態と共通する構成については同一符号を付して説明を省略する。
図7は、第4実施形態に係る鉄道車両のドア装置310の図2相当の図面である。図7に示すように、第4実施形態では、第1弾性部材321の第1突出壁部325に形成された小溝325dと、第2弾性部材322の第2及び第3突出壁部326,327に形成された小溝326d,327dとが、ドアスライド方向の位置において互いにずれている。これにより、第1突出壁部325と第2突出壁部326との間及び第1突出壁部325と第3突出壁部327との間の流路を蛇行形状に形成することができる。なお、第1実施形態と共通する構成については同一符号を付して説明を省略する。
図8は、第5実施形態に係る鉄道車両のドア装置410の図2相当の図面である。図8に示すように、第5実施形態では、第1弾性部材421の第1突出壁部425の側面と、第2弾性部材422の第2及び第3突出壁部426,427の側面とには、溝の代わりに、突起425d,426d,427dが設けられている。これらの突起425d,426d,427dは、第1~4実施形態の溝と同様に、鉛直方向に沿って延びている。また、第1突出壁部425の突起425dと、第2及び第3突出壁部426,427の突起426d,427dとは、ドアスライド方向の位置において互いにずれている。なお、第1実施形態と共通する構成については同一符号を付して説明を省略する。
図9は、第6実施形態に係る鉄道車両のドア装置510の図2相当の図面である。図9に示すように、第6実施形態では、第1弾性部材521において、その第1基部523の一端部から第1突出壁部525がドアスライド方向に突出し、第2弾性部材522において、その第2基部524の他端から第2突出壁部526がドアスライド方向に突出している。即ち、全閉状態における第1弾性部材521及び第2弾性部材522の全体のドア厚み方向及びドアスライド方向の中心点Pを基準として、第1弾性部材521は、第2弾性部材522と点対称な形状である。第1突出壁部525及び第2突出壁部526の根元側部分525a,526aには、ドア厚み方向に窪んだ大溝525c,526cが形成され、第1突出壁部525と第2突出壁部526との対向面には、ドア厚み方向に窪んだ複数の小溝525d,526dが形成されている。さらに、第1基部523及び第2基部524には、第1突出壁部525及び第2突出壁部526と隙間をあけた凸部528,529がそれぞれドアスライド方向に突出しているが、その先端面にはドアスライド方向に窪んだ小溝528e,529eが形成されている。これによれば、第1突出壁部525と第2突出壁部526を厚肉にできるため、耐久性を高めることができる。なお、第1実施形態と共通する構成については同一符号を付して説明を省略する。
図10は、第7実施形態に係る鉄道車両のドア装置610の図2相当の図面である。図10に示すように、第7実施形態では、第1弾性部材621の第1突出壁部625の先端に、凹部625eが形成されている。第2弾性部材622には、第2突出壁部626と第3突出壁部627との間に第4突出壁部628が設けられており、その第4突出壁部628が、側引戸11,12が全閉の状態において凹部625eに非接触で挿入される。第1突出壁部625と第2及び第3突出壁部626,627との対向面には、ドア厚み方向に窪んだ複数の小溝625d,626d,627dが形成され、さらに、第4突出壁部628の凹部625eとの対向面にも小溝628dが形成されている。なお、第1実施形態と共通する構成については同一符号を付して説明を省略する。
