Description

【０００１】
【発明の属する技術分野】
本発明は車両用ドアの窓ガラス取り付け方法とこれによるいわゆる嵌め殺しの窓構造に関するものである。
【０００２】
【従来の技術】
図９に示す本実施の形態に係る車両用ドアを参照して、鉄道車両における車両用ドア１において、その窓開口２の内外一方の側に開放した段差部３に窓ガラス４を当てがって接着して取り付ける簡易な構造が従来から採用されている。しかし、段差部３と窓ガラス４と段差の間のシールが甘いと、列車のすれ違い時の風圧による圧力の変動などにより雨水が車外側から車内側に浸入しやすい。
【０００３】
そこで、段差部３と窓ガラス４との間の接着は、溶剤で流動性を与えたシール材５ａを塗布して固化させ接着と同時にシール５を施す方式が一般に採用されている。この場合、十分なシールを確保するのにシール５は所定の厚みが必要である。
【０００４】
しかし、シール材５ａを最初から所定の厚みに盛っておいて、窓ガラス４を載せ所定の位置に押し付けて位置決めしようとすると、シール材５ａの流動性のために窓ガラス４が位置ずれして位置決めしにくい。このため、従来、段差部３に所々に配したパッド６の上に載置することにより所定量浮かせて支持した状態で、最初シール材５ａをパッド６の高さ程度まで少なく盛って窓ガラス４を安定に位置決めしておき、その後シール材５ａを補給するようにしている。
【０００５】
【発明が解決しようとする課題】
しかし、上記のように最初シール材５ａそ少なく盛っておき、窓ガラス４の位置決め後、さらにシール材５ａを内外共所定の厚みに盛るのでは作業性が悪く、簡易な窓構造のわりには生産性が上がらない。また、前記のように流動性のあるシール材５ａの上に載せて窓ガラス４を位置決めしシール材５ａの固化を図るのでは、車両用ドアが横に寝かされていることが必須となり、作業に大きな平面スペースが要るので同時に作業する枚数が多いほど必要スペースが勢い増大し、製品コスト上昇の原因になる。しかも、列車に建てつけたまま破損した窓ガラスを取り替えられない不便がある。
【０００６】
本発明の目的は、シール材の塗布および窓ガラスの位置決めが１段階でしかも車両用ドアの向きを問わないで簡単かつ短時間に行なえる車両用ドアおよびその窓ガラスの取り付け方法を提供することにある。
【０００７】
【課題を解決するための手段】
上記の目的を達成するために、本発明の車両用ドアは、窓開口の内外一方の側に開放した段差部のコーナ部に弾性パッドを介して窓ガラスの外周部が当てがわれているとともに、弾性パッドと段差部との間、および弾性パッドと窓ガラスとの間が接着されており、段差部の窓ガラスの一面側と他面側とにおいて、段差部と弾性パッドとの境界部および弾性パッドと窓ガラスとの境界部の双方に跨って形成されたシール溜まりにてシールが施されていることを主たる特徴としている。
【０００８】
このような構成では、弾性パッド自体が、段差部のコーナ部に当てがわれていることにより、段差部の所定の位置に位置決めされ、かつ段差部への弾性による密着性を活かした接着によって車両用ドアの向きに関係なく前記位置決め状態を確固に保たれるし、窓ガラス自体は段差部との間に前記弾性パッドが介在している方向において、前記位置決め状態の弾性パッドによって、段差部との互いの寸法誤差や位置の誤差を弾性パッドの弾性によって吸収されながら、段差部からほぼ所定の位置にあるよう一義的に位置決めされ、かつ弾性パッドへの弾性による密着性を活かした接着によって車両用ドアの向きに関係なく前記位置決め状態を確固に保たれる。しかも、窓ガラスをこのように位置決め保持して段差部の窓ガラスの一面側と他面側とに形成される、段差部と弾性パッドとの境界部および弾性パッドと窓ガラスとの境界部の双方に跨ったシール溜まりにて前記シールが施されていることにより、このシールのためのシール材を前記シール溜まりに必要量一挙に充填しても、シール材はその粘性と濡れ性とによって車両用ドアの向きに関係なく前記シール溜まりに安定に存在し、偏ったり流失したりせずに固化されて、窓ガラスを前記位置決め位置に確固に固定し、前記シールを達成することができる。従って、弾性パッドの装着と接着は伴うが、速乾性接着剤を用いるなどすれば時間的影響が緩和できると共に、弾性パッドの使用および窓ガラスとの接着によって、窓ガラスの位置決め保持が極く簡略化するので、全体としてシール材の塗布および窓ガラスの位置決めが１段階でしかも車両用ドアの向きを問わないで簡単かつ短時間に行なえる。
【０００９】
このような車両用ドアを製作する上での、車両用ドアの窓開口に形成された内外一方の側に開放した段差部に窓ガラスを当てがい固定する車両用ドアの窓ガラス取り付け方法としては、前記段差部のコーナ部に弾性パッドを当てがって接着した後、弾性パッドに窓ガラスの外周部を当てがい位置決めして接着し、段差部の窓ガラスの一面側と他面側とにおいて、段差部と弾性パッドとの境界部および弾性パッドと窓ガラスとの境界部の双方に跨って形成したシール溜まりにシール材を充填して固化させるシールを施し、窓ガラスを取り付けることを主たる特徴とすれば足り、上記のような車両用ドアが上記特長を活かして製作することができ、製品コストが低減する。また、車両に建て付け状態の車両用ドアに対してもそのまま窓ガラスを取り付けることができるので、破損した窓ガラスを取り替えるのに便利で、低コストで対応することができる。
【００１０】
弾性パッドがコーナ部に沿う鉤型断面形状であると、弾性パッドによる窓ガラスの一義的な位置決めが、段差部に対して窓ガラスの厚み方向および平面方向の双方につき弾性パッドのコーナ部への当てがいによって一挙に完了する利点があり、しかも、縦向きの車両用ドアにおいて窓ガラスを取り付けるときにも平面方向の位置決めが自重によりずれるようなことが防止されるので、平面方向への位置決め状態で窓ガラスを弾性パッドに接着するのが容易である。この場合、弾性パッドが発泡樹脂部材であると、弾性に富む分だけ段差部や窓ガラスとの密着性が向上するし、段差部とこれに嵌り合う窓ガラスとの平面方向における寸法や位置の誤差を吸収しやすく、弾性パッドに窓ガラスを当てがい嵌め合せる作業が無理なく容易に行える。また、発泡樹脂部材である弾性パッドの窓ガラスの下辺に対応する範囲が非発泡樹脂部材であると、窓ガラスを弾性パッドに当てがい接着する作業を縦向きの車両用ドアについて行なうのに、弾性パッドが窓ガラスの重量を変形なく受止めて窓ガラスを所定位置に安定に保持することができる。
【００１２】
本発明のそれ以上の目的および特徴は、以下の詳細な説明および図面の記載によって明らかになる。本発明の各特徴は、可能な限りにおいてそれ単独で、あるいは種々な組み合わせで複合して用いることができる。
【００１３】
【発明の実施の形態】
以下、本発明の実施の形態に係る車両用ドアとその窓ガラス取り付け方法について、図１〜図９を参照しながら詳細に説明し、本発明の理解に供する。
【００１４】
本実施の形態は鉄道車両の側構体に設けられる出入り口に使用される車両用ドアに本発明を適用した場合の一例である。しかし、本発明はこれに限られることはなく鉄道車両の他の部分に使用される車両用ドア、バスなど他の車両に使用される車両用ドアにおける嵌め殺し窓構造全般に適用して有効であり、いずれも本発明の範疇に属する。
【００１５】
本実施の形態に係る車両用ドアは図１〜図９に示すように、窓開口２の内外一方の側に開放した段差部３のコーナ部３ａに弾性パッド６を介して窓ガラス４の外周部が当てがわれている。弾性パッド６と段差部３との間、および弾性パッド６と窓ガラス４との間が接着剤７により接着されている。段差部３の窓ガラス４の一面側と他面側とにおいて、段差部３と弾性パッド６との境界部３６および弾性パッド６と窓ガラス４との境界部４６の双方に跨って形成されたシール溜まり８にてシール５が施されている。図示するところは一例として、車内に向け開放した段差部３に窓ガラス４を取り付けているが、これに限られない。また、段差部３は窓ガラス４を取り付ける側だけに形成してもよいし、窓ガラス４を取り付けない側にも形成するようにしてもよい。その選択はこれらの窓構造を持った車両用ドア１の意匠設計による。また、段差部３の形状も種々に選択できるが、少なくとも窓ガラス４を取り付ける部分についてはほぼ鉤型の断面形状にするのが窓ガラス４の後述する位置決めに好適である。
【００１６】
上記のように弾性パッド６自体が、段差部３のコーナ部３ａに当てがわれていることにより、段差部３の所定の位置に位置決めされ、かつ段差部３への弾性による密着性を活かした接着によって車両用ドア１の向きに関係なく前記位置決め状態を確固に保たれる。同時に、窓ガラス４自体は段差部３との間に弾性パッド６が介在している方向において、前記位置決め状態の弾性パッド６によって、段差部３との互いの寸法誤差や位置の誤差を弾性パッド６の弾性によって吸収されながら、段差部３からほぼ所定の位置にあるよう一義的に位置決めされ、かつ弾性パッド６への弾性による密着性を活かした接着によって車両用ドア１の向きに関係なく前記位置決め状態を確固に保たれる。
【００１７】
しかも、窓ガラス４をこのように位置決め保持して段差部３の窓ガラス４の一面側と他面側とに形成される、段差部３と弾性パッド６との境界部３６および弾性パッド６と窓ガラス４との境界部４６の双方に跨ったシール溜まり８にて前記シール５が施されていることにより、このシール５のためのシール材５ａを前記シール溜まり８に必要量一挙に塗布、充填しても、シール材５ａはその粘性と濡れ性とによって車両用ドア１の向きに関係なく前記シール溜まり８に安定に存在し、偏ったり流失したりせずに固化されて、窓ガラス４を前記位置決め位置に確固に固定し、前記シール５を達成することができる。なお、一例として弾性パッド６はＣＲ材が好適であり、シール材５ａはシーカ２６５が好適である。
【００１８】
以上によって、弾性パッド６の装着と接着は伴うが、速乾性接着剤７を用いるなどすれば時間的影響が緩和できると共に、弾性パッド６の使用および窓ガラス４との接着によって、窓ガラス４の位置決め保持が極く簡略化するので、全体としてシール材５ａの塗布および窓ガラス４の位置決めが１段階でしかも車両用ドア１の向きを問わないで簡単かつ短時間に行なえる。
【００１９】
このような車両用ドア１を製作する上での、車両用ドア１の窓開口２に形成された内外一方の側に開放した段差部３に窓ガラス４を当てがい固定する車両用ドア１の窓ガラス取り付け方法としては、先ず、段差部３のコーナ部３ａに弾性パッド６を当てがって接着剤７によって接着した後、弾性パッド６に窓ガラス４の外周部を当てがい位置決めして接着剤７により接着する。次いで、段差部３の窓ガラス４の一面側と他面側とにおいて、段差部３と弾性パッド６との境界部３６および弾性パッド６と窓ガラス４との境界部４６の双方に跨って形成したシール溜まり８にシール材５ａを充填して固化させるシール５を施し、窓ガラス４を取り付ければ足り、上記のような窓構造を持った車両用ドア１が上記特長を活かして製作することができ、製品コストが低減する。また、車両に建て付け状態の車両用ドア１に対してもそのままで上記手法にて窓ガラス４を取り付けることができるので、破損した窓ガラス４を取り替えるのに便利で、低コストで対応することができる。
【００２０】
図１〜図８に示す例では、弾性パッド６がコーナ部３ａに沿う鉤型断面形状である。このような弾性パッド６による窓ガラス４の一義的な位置決めは、段差部３に対して窓ガラス４の厚み方向および平面方向の双方につき弾性パッド６のコーナ部６ａへの当てがいによって一挙に完了する利点がある。しかも、縦向きの車両用ドア１において窓ガラス４を取り付けるときにも平面方向の位置決めが自重によりずれるようなことが防止されるので、平面方向への位置決め状態で窓ガラス４を弾性パッド６に接着するのが容易である。
【００２１】
弾性パッド６が前記ＣＲなどを発泡させたＣＲスポンジなどの発泡樹脂部材６ｂであると、非発泡よりも弾性に富む分だけ段差部３や窓ガラス４との密着性が向上するし、段差部３とこれに嵌り合う窓ガラス４との平面方向における寸法や位置の誤差を吸収しやすく、弾性パッド６に窓ガラス４を当てがい嵌め合せる作業が無理なく容易に行える。また、図３、図４に示す例のように発泡樹脂部材６ｂである弾性パッド６における窓ガラス４の下辺に対応する範囲が図４に示すように非発泡樹脂部材６ｃで、他の部分が図５に示すように発泡樹脂部材６ｂであると、窓ガラス４を弾性パッド６に当てがい接着する作業を縦向きの車両用ドア１について行なうのに、弾性パッド６における非発泡樹脂部材６ｃが窓ガラス４の重量を変形なく受止めて窓ガラス４を所定位置に安定に保持することができる。図１に示す例では、さらに、車両用ドア１は左右ないしは前後の縦骨１１、１２および図示しないが上下の上骨および下骨が共にアルミニウムの押し出し形材よりなり、これらの間に心材１３を充填したものの車内側および車外側にステンレス鋼よりなる内板１４および外板１５を張り合せてある。窓開口２はこれら内外板１４、１５が形成しており、窓開口２の口縁２ａは内外板１４、１５が二重に接合された接合縁１４ａ、１５ａが形成している。
【００２２】
接合縁１４ａ、１５ａは窓開口２におけるドア厚み方向のほぼ中間の位置にあり、段差部３はこの接合縁１４ａ、１５ａから車内側への内板１４の屈曲によって直角な鉤型面を持つように形成されている。窓ガラス４は１枚構成であって、弾性パッド６はコーナ部３ａに沿う鉤型断面形状でその一辺６ｄがコーナ部３ａから接合縁１４ａに沿ってその途中位置まで延び接合縁１４ａ、１５ａと窓ガラス４との間にシール溜まり８を形成している。接合縁１４ａよりも接合縁１５ａの方が長く、双方の接合境界部が前記シール溜まり８に面している。これによって、このシール溜まり８にシール材５ａを塗布、充填し固化させると、弾性パッド６と窓ガラス４との境界部４６、弾性パッド６と段差部３との境界部３６、および接合縁１４ａ、１５ａの接合境界部、のそれぞれに跨ったシール５が施せる。鉤型断面形状をした弾性パッド６の他辺６ｅはコーナ部３ａから窓ガラス４の車内側面と面一になる位置まで延び、窓ガラス４とともに段差部３との間に直角なコーナ部によるシール溜まり８を形成している。これによって、このシール溜まり８にシール材５ａを塗布、充填して固化させると、弾性パッド６と段差部３との境界部３６、弾性パッド６と窓ガラス４との境界部４６、の双方に跨ったシール５が施せる。
【００２３】
車両用ドア１の戸先側では内外板１４、１５を縦骨１１の前端部へ折り曲げたフランジ１４ｂ、１５ｂを利用して戸先ゴム２１を装着してある。また、車両用ドア１の戸尻側では風止めシール部材２２が設けられている。この風止めシール部材２２は戸尻部材である縦骨１２の内外板１４、１５によって覆われない戸尻部に一体形成された車外側に向く溝２３またはおよびフランジ２４に基部２２ａを弾性的に嵌め合わせて取り付けられている。これにより、特別な取り付け部材なしに風止めシール部材２２を戸尻に設けることができるのでコストが低減するし、車外側に向く溝２３またはおよびフランジ２４に基部２２ａが嵌め合わされるので、風止めシール部材２２のシール部であるシール片２２ｂなどが車外側部材に摺接する完全なエアタイト構造を採用しても、風止めシール部材２２は前記車外側部材との摺接により働く押し戻し力によって溝２３またはおよびフランジ２４に押し付けられるので、嵌め合せによる取り付けが原因して脱落するようなことはなくエアタイト機能を長期に安定して発揮することができる。
【００２４】
風止めシール部材２２は基部２２ａが二股断面をなしてフランジ２４に跨るように圧入して嵌め合せ、二股断面部分の一方が溝２３に入り込むようにしてあり、溝２３は風止めシール部材２２の保持に直接役立ってはいない。しかし、溝２３に基部２２ａを圧入する方式にて取り付けることもできるし、溝２３およびフランジ２４を併用して取り付けることもできる。なお、風止めシール部材２２の基部２２ａは戸尻側に露出する構造としてあり、車両用ドア１が開かれたときに戸尻受に当接する戸尻ゴムに共用することができる。
【００２５】
風止めシール部材２２はゴム部材よりなり、二股断面をした基部２２ａ内にはこれに沿ったＵ字状断面をしたバネ鋼製の心材２５がインサートされて弾性的な掴持力を発揮するようにしてあり、基部２２ａ内面に一体成形している返り片２２ｃとともに基部２２ａがフランジ２４から抜けるのを防止している。心材２５は両側片の先端から基部に向けて切り込んだ図示しない切り込みが形成されたいわゆるムカデ型をしたもので、車両用ドア１が縦方向に湾曲していてもこれに風止めシール部材２２が沿うように曲げられるのを妨げないようにしている。
【００２６】
図２に示す例は、窓ガラス４が複数枚の窓ガラス４１、４２をスペーサ３１で貼り合わせた複層ガラスであって、弾性パッド６はコーナ部３ａから車内側に延びる他片６ｅが段差部３の最開放側、つまり最車内側の窓ガラス４１とその手前の窓ガラス４２との間にまで延びて位置し、窓ガラス４の車内側面よりも車外側に後退したシール溜まり８を形成している。これによって、窓ガラス４が複層ガラスで厚さが大きくても、これの影響なくシール溜まり８の前記車外側への後退によって、シール５を施すのに十分な容量が得られやすくしている。同時に内外板１４、１５の接合縁１４ａ、１５ａは車両用ドア１の車外面側に寄った、より具体的には面一になるようにして、複層ガラスである窓ガラス４を嵌め合せて上記のように取り付けるのに十分な奥行き寸法を持った段差部３が得られるようにしている。さらに、段差部３の周壁はその奥行き方向に車内側が広く車外側が狭くなる若干の傾斜を持たせることによっても、前記シール溜まり８の容量が大きくなるようにしてある。
【００２７】
また、縦骨１２の戸尻部に前記溝２３、フランジ２４に加え、さらに溝２６、フランジ２７も一体形成し、風止めシール部材２２における二股状基部２２ａの戸尻側片を溝２６に圧入して風止めシール部材２２がさらに脱落しにくくしている。他の構成は図１に示す例と同じであるので、同種の部材には同一の符号を付し、重複する図示および説明は省略する。
【００２８】
図３、図４に示す例は、前記した窓ガラス４の取り付け構造のほか、車両用ドア１の本体を大型で押し出し方向が縦向きになるように用いる形材３２によって形成して所定の高さ部分に窓開口２を明け、形材３２が左右に形成している段差部３と窓開口２を持った溝３３の上下に、図４に示す内板１４と、この内板１４と形材３２との間の隙間を閉じて形材３２とで段差部３を形成する隔壁３４とを設ける。図４に示す例では隔壁３４は形材３２の側に溶接などして一体に設け、内板１４との間の隙間はシール５によって封止するようにしている。他の構成は図１を参照して述べたところと特に変わりはなく、同種の部材には同一の符号を付して重複する図示および説明は省略する。
【００２９】
図５に示す例は、図３、図４に示した例の場合に加え、さらに、段差部３の周壁に車内側からスペーサ３９を介して被さる化粧カバー３７を設けてねじないしはリベット３８によりねじ止めないしはリベット止めし、ねじ止めないしはリベット止め部がシール５により隠れるようにしてある。形材３２の戸先側には内向きに対向し合う一対のフランジ３２ａを設け、これらフランジ３２ａに戸先ゴム２１を嵌め合せて装着してある。他の構成は図３、図４を参照して述べたところと特に変わるところはなく、同種の部材には同一の符号を付して重複する図示および説明は省略する。
【００３０】
図６に示す例は、図５に示す例における一枚ガラスの窓ガラス４を複層ガラスにした場合を示し、段差部３の周壁が傾斜していない以外は図２またはおよび図５を参照して述べたところと特に変わるところはなく、同種の部材には同一の符号を付し重複する図示および説明は省略する。
【００３１】
図７に示す例は、図１に示すような縦骨１１、１２および上下の骨と内外板１４、１５を持った車両用ドア１において、窓開口２に沿う形材４３を設け、この形材４３に段差部３を形成している。外板１５がなす口縁１５ａは形材４３の段差部３よりも内側に長く延びて接合され、接合縁１５ａと段差部３との接合境界部が、弾性パッド６と段差部３の境界部３６、弾性パッド６と窓ガラス４との境界部４６とともにシール溜まり８に臨み、それらに跨るシール５が施されるようにしてある。
【００３２】
内板１４の左右エッジは形材４３と縦骨１１、１２との段差部３に受止められ、この受止め部に化粧カバー３７が被さるようにしてある。縦骨１１に被さる化粧カバー３７は外板１５のフランジ１５ｂと対向するように折り曲げたフランジ３７ａを有し、これら両フランジ１５ｂ、３７ａに戸先ゴム２１を嵌め合せて装着してある。他の構成は図１〜図６において説明したところと重複するので、同種の部材には同一の符号を付し、重複する図示および説明は省略する。
【００３３】
図８に示す例は、図７の例における一枚ガラスの窓ガラス４に代えて複層ガラスとした点と、戸先部の化粧カバー３７を省略して縦骨１１の溝４４内に内板１４のエッジを受入れてカバーしている点と、外板１５のフランジ１５ｂと対向するフランジ１１ａを縦骨１１に一体成形して、これらフランジ１５ｂ、１１ａに戸先ゴム２１を嵌め合わせて装着した点で、図７に示す例と異なる。他の構成は図７に示す例と特に変わるところはなく、同種の部材には同一の符号を付し重複する説明は省略する。
【００３４】
図９に示す例は、弾性パッド６を窓ガラス４の車外側の面に沿う扁平な形状のものとして単純化し、小さな厚み寸法で窓ガラス４を固定しシールできる利点がある。この場合、窓ガラス４の外周と段差部３との間にシール溜まり８が形成される。弾性パッド６は窓ガラス４が当てがわれてもその面方向に一義的には位置決めできないが、面方向に位置決めして接着することにより位置決め状態が保たれるので、速乾性の接着剤７を用いることによって、横に寝かした車両用ドア１に窓ガラス４を取り付ける場合はもとより、縦向きの車両用ドア１に窓ガラス４を取り付ける場合でも窓ガラス４を面方向に位置決めして弾性パッド６に押し当て接着するだけでよく、特に作業しにくくなるようなことはない。これも本発明の範疇に属する。他の構成は図１に示す例と特に変わるところはなく、同種の部材には同一の符号を付し、重複する図示および説明は省略する。
【００３５】
図１０に示す例は、図３に示す例の変形例を示し、形材３２が形成している段差部３の車内側に窓ガラス４の着脱を邪魔しない大きさのフランジ５１を形成し、コーナ形状だけでなく深さのあるシール溜まり８が形成できるようにしてある。
【００３６】
図１１に示す例は、図４に示す例の内板１４を、形材３２に形成したフランジ５２との嵌め合せによって前後左右に支持するようにしてある。この支持のために内板１４をも形材としてフランジ５２と係合するフランジ５３を形成するとともに、このフランジ５３とフランジ５２との係合を保つように形材３２との間で突っ張る突っ張り壁５４を一体に形成している。
【００３７】
【発明の効果】
本発明によれば、上記の説明で明らかなように、弾性パッドの装着と接着は伴うが、速乾性接着剤を用いるなどすれば時間的影響が緩和できると共に、弾性パッドの使用および窓ガラスとの接着によって、窓ガラスの位置決め保持が極く簡略化するので、全体としてシール材の塗布および窓ガラスの位置決めが１段階でしかも車両用ドアの向きを問わないで簡単かつ短時間に行なえ、製品コストが低減する。また、車両に建て付け状態の車両用ドアに対してもそのまま窓ガラスを取り付けることができるので、破損した窓ガラスを取り替えるのに便利で、低コストで対応することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a method for attaching a window glass of a vehicle door and a so-called fitting window structure.
[0002]
[Prior art]
With reference to the vehicle door according to the present embodiment shown in FIG. 9, in the vehicle door 1 in a railway vehicle, a window glass 4 is applied to the stepped portion 3 opened to one of the inside and outside of the window opening 2. Conventionally, a simple structure that is attached by bonding is used. However, if the seal between the stepped portion 3 and the window glass 4 and the stepped portion is not good, rainwater tends to enter the inside of the vehicle from the outside of the vehicle due to pressure fluctuations caused by wind pressure when the train passes.
[0003]
Therefore, a method of applying the seal 5 at the same time as the adhesion is generally adopted for the adhesion between the stepped portion 3 and the window glass 4 by applying and solidifying the sealing material 5a which has been given fluidity with a solvent. In this case, the seal 5 needs to have a predetermined thickness to ensure a sufficient seal.
[0004]
However, when the sealing material 5a is piled up to a predetermined thickness from the beginning and the window glass 4 is placed and pressed and positioned at a predetermined position, the window glass 4 is displaced due to the fluidity of the sealing material 5a. Difficult to position. For this reason, conventionally, the window glass 4 is first deposited with the sealing material 5a less than the height of the pad 6 in a state where it is supported by being floated by a predetermined amount by being placed on the pad 6 disposed in places in the stepped portion 3. Is positioned stably, and then the sealing material 5a is replenished.
[0005]
[Problems to be solved by the invention]
However, as described above, the seal material 5a is initially deposited in a small amount, and after the window glass 4 is positioned, the seal material 5a is further deposited to a predetermined thickness both inside and outside, so that workability is poor, and production is performed instead of a simple window structure. Sex does not go up. Moreover, in order to position the window glass 4 and to solidify the sealing material 5a by placing it on the fluid sealing material 5a as described above, it is essential that the vehicle door be laid down sideways. Since a large plane space is required for the work, the necessary space increases as the number of sheets to be worked simultaneously increases, which causes an increase in product cost. Moreover, there is an inconvenience that a broken window glass cannot be replaced while it is still installed on the train.
[0006]
SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle door and a method for attaching the window glass, in which the application of the sealing material and the positioning of the window glass can be performed in one step easily and in a short time regardless of the direction of the vehicle door. It is in.

In order to achieve the above object, in the vehicle door of the present invention, the outer peripheral portion of the window glass is applied to the corner portion of the stepped portion opened on one side of the window opening through the elastic pad. And between the elastic pad and the stepped portion, and between the elastic pad and the window glass, and on the one side and the other side of the stepped portion of the window glass, the boundary between the stepped portion and the elastic pad and The main feature is that a seal is formed by a seal pool formed across both boundary portions of the elastic pad and the window glass.
[0008]
In such a configuration, the elastic pad itself is positioned at a predetermined position of the stepped portion by being applied to the corner portion of the stepped portion, and the vehicle is bonded by utilizing the adhesion due to elasticity to the stepped portion. Regardless of the orientation of the door, the positioning state is firmly maintained, and in the direction in which the elastic pad is interposed between the window glass itself and the stepped portion, the positioning pad and the stepped portion While the mutual dimensional error and position error are absorbed by the elasticity of the elastic pad, the vehicle is uniquely positioned so as to be almost at a predetermined position from the stepped portion, and the vehicle is bonded by utilizing the adhesion by the elasticity to the elastic pad. Regardless of the orientation of the door, the positioning state can be securely maintained. In addition, the window glass is positioned and held in this way, and formed on the one side and the other side of the step glass, and the boundary between the step and the elastic pad and the boundary between the elastic pad and the window glass. Since the seal is applied in the seal pool straddling both sides, even if the seal material for the seal is filled in the seal pool in a necessary amount at once, the seal material is a vehicle depending on its viscosity and wettability. Regardless of the orientation of the door, it can be stably present in the seal reservoir and solidified without being biased or washed away, and the window glass can be firmly fixed at the positioning position to achieve the seal. Therefore, although the attachment and adhesion of the elastic pad are accompanied, the influence of time can be reduced by using a quick-drying adhesive, and the positioning and holding of the window glass is very simple by using the elastic pad and bonding with the window glass. Therefore, as a whole, the application of the sealing material and the positioning of the window glass can be performed easily and in a short time regardless of the direction of the vehicle door.
[0009]
When manufacturing such a vehicle door, as a method for attaching the window glass of the vehicle door to fix the window glass to the stepped portion opened on the inner or outer side formed in the window opening of the vehicle door, After attaching the elastic pad to the corner portion of the stepped portion and bonding the elastic pad, the outer peripheral portion of the window glass is positioned and bonded to the elastic pad, and on one side and the other side of the stepped portion of the window glass The main feature is that the window glass is attached by applying a seal that fills and solidifies the seal reservoir formed across both the boundary between the stepped portion and the elastic pad and the boundary between the elastic pad and the window glass. As a result, the vehicle door as described above can be manufactured taking advantage of the above features, and the product cost can be reduced. Further, since the window glass can be attached as it is to the vehicle door built in the vehicle, it is convenient to replace the damaged window glass and can be handled at low cost.
[0010]
When the elastic pad has a saddle-shaped cross-sectional shape along the corner portion, the unambiguous positioning of the window glass by the elastic pad is applied to the corner portion of the elastic pad in both the thickness direction and the planar direction of the window glass with respect to the stepped portion. Positioning in the plane direction is possible because there is an advantage that it can be completed all at once by the padding, and the positioning in the plane direction is prevented from shifting due to its own weight even when installing the window glass in the vertical vehicle door. It is easy to bond the window glass to the elastic pad. In this case, if the elastic pad is a foamed resin member, the adhesiveness between the stepped portion and the window glass is improved by the amount of elasticity, and the size and position of the stepped portion and the window glass fitted to the stepped portion in the planar direction are improved. It is easy to absorb errors, and the work of fitting the window glass to the elastic pad can be done easily without difficulty. In addition, when the range corresponding to the lower side of the window glass of the elastic pad that is a foamed resin member is a non-foamed resin member, to perform the work of attaching the window glass to the elastic pad and bonding it to the vertical vehicle door, The elastic pad can receive the weight of the window glass without deformation and stably hold the window glass at a predetermined position.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a vehicle door and a method for attaching a window glass thereof according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 9 to provide an understanding of the present invention.
[0014]
This embodiment is an example of the case where the present invention is applied to a vehicle door used at a doorway provided in a side structure of a railway vehicle. However, the present invention is not limited to this, and is effective when applied to a general window structure for a vehicle door used for other parts of a railway vehicle, a vehicle door used for other vehicles such as a bus. Yes, both belong to the category of the present invention.
[0015]
As shown in FIGS. 1 to 9, the vehicle door according to the present embodiment has an outer periphery of the window glass 4 via an elastic pad 6 on a corner portion 3 a of a stepped portion 3 opened to one of the inside and outside of the window opening 2. Department is assigned. An adhesive 7 bonds the elastic pad 6 and the stepped portion 3, and the elastic pad 6 and the window glass 4. On one side and the other side of the window glass 4 of the stepped portion 3, it is formed across both the boundary portion 36 between the stepped portion 3 and the elastic pad 6 and the boundary portion 46 between the elastic pad 6 and the windowglass 4. A seal 5 is applied in a seal reservoir 8. As an example, the window glass 4 is attached to the stepped portion 3 opened toward the inside of the vehicle. However, the present invention is not limited to this. Further, the stepped portion 3 may be formed only on the side to which the window glass 4 is attached, or may be formed on the side to which the window glass 4 is not attached. The selection depends on the design of the vehicle door 1 having these window structures. Moreover, although the shape of the level | step difference part 3 can also be selected variously, it is suitable for the positioning which the window glass 4 mentions later that it is a substantially bowl-shaped cross-sectional shape about the part which attaches the window glass 4 at least.
[0016]
As described above, since the elastic pad 6 itself is applied to the corner portion 3a of the step portion 3, the elastic pad 6 is positioned at a predetermined position of the step portion 3 and takes advantage of the adhesion to the step portion 3 due to elasticity. The positioning state is securely maintained regardless of the direction of the vehicle door 1 by bonding. At the same time, in the direction in which the elastic pad 6 is interposed between the window glass 4 itself and the stepped portion 3, the elastic pad 6 in the positioning state causes the dimensional error and position error of the stepped portion 3 to be elastic. 6 is absorbed by the elasticity of 6 and is uniquely positioned so as to be substantially at a predetermined position from the stepped portion 3, and is bonded regardless of the orientation of the vehicle door 1 by adhesion utilizing elasticity to the elastic pad 6. The positioning state is firmly maintained.
[0017]
In addition, the window glass 4 is positioned and held in this way, and the boundary portion 36 between the step portion 3 and the elastic pad 6 and the elastic pad 6 are formed on one side and the other side of the window glass 4 of the step portion 3. By applying the seal 5 at the seal reservoir 8 straddling both the boundary portions 46 with the window glass 4, the seal material 5a for the seal 5 is applied to the seal reservoir 8 in a necessary amount at once. Even after filling, the sealing material 5a stably exists in the seal reservoir 8 regardless of the orientation of the vehicle door 1 due to its viscosity and wettability, and is solidified without being biased or washed away. Can be firmly fixed to the positioning position to achieve the seal 5. As an example, the elastic pad 6 is preferably a CR material, and the sealer 5a is preferably a seeker 265.
[0018]
As described above, the elastic pad 6 is attached and adhered, but if the quick-drying adhesive 7 is used, the influence of time can be mitigated, and the use of the elastic pad 6 and adhesion with the window glass 4 allows the window glass 4 to be bonded. Since the positioning and holding is greatly simplified, the application of the sealing material 5a and the positioning of the window glass 4 as a whole can be performed easily and in a short time regardless of the orientation of the vehicle door 1.
[0019]
When manufacturing such a vehicle door 1, the vehicle door 1 is fixed by applying a window glass 4 to a stepped portion 3 opened on one of the inner and outer sides formed in the window opening 2 of the vehicle door 1. As a method for attaching the window glass, first, the elastic pad 6 is applied to the corner portion 3a of the stepped portion 3 and adhered by the adhesive 7, and then the outer peripheral portion of the window glass 4 is applied to the elastic pad 6 for positioning and bonding. Adhesive with agent 7. Next, on one side and the other side of the window glass 4 of the stepped portion 3, it is formed across both the boundary portion 36 between the stepped portion 3 and the elastic pad 6 and the boundary portion 46 between the elastic pad 6 and the windowglass 4. It is sufficient that the seal reservoir 8 is filled with the sealant 5a to be solidified and the window glass 4 is attached, and the vehicle door 1 having the above-described window structure can be manufactured taking advantage of the above-described features. Product cost. In addition, since the window glass 4 can be attached to the vehicle door 1 in a state of being built in the vehicle by the above method as it is, it is convenient to replace the damaged window glass 4 and copes with low cost. Can do.
[0020]
In the example shown in FIGS. 1 to 8, the elastic pad 6 has a bowl-shaped cross-sectional shape along the corner portion 3a. Such unambiguous positioning of the window glass 4 by the elastic pad 6 is completed at once by applying the elastic pad 6 to the corner portion 6a in both the thickness direction and the plane direction of the window glass 4 with respect to the stepped portion 3. There are advantages to doing. Moreover, since the positioning in the plane direction is prevented from shifting due to its own weight even when the window glass 4 is attached to the longitudinal vehicle door 1, the window glass 4 is placed on the elastic pad 6 in the positioning state in the plane direction. Easy to glue.
[0021]
When the elastic pad 6 is a foamed resin member 6b such as CR sponge obtained by foaming the CR or the like, the adhesiveness to the stepped portion 3 and the window glass 4 is improved by the amount richer in elasticity than non-foamed, and the stepped portion 3 and the window glass 4 fitted to the window glass 4 can be easily absorbed by fitting the window glass 4 to the elastic pad 6 without any errors in dimensions and positions in the planar direction. Further, as shown in FIG. 3 and FIG. 4, the range corresponding to the lower side of the window glass 4 in the elastic pad 6 which is the foamed resin member 6b is the non-foamed resin member 6c as shown in FIG. As shown in FIG. 5, when the foamed resin member 6 b is used, the non-foamed resin member 6 c in the elastic pad 6 is used to perform the work of attaching the window glass 4 to the elastic pad 6 and bonding the window glass 4 to the vertical vehicle door 1. The window glass 4 can be stably held at a predetermined position by receiving the weight of the window glass 4 without deformation. In the example shown in FIG. 1, the vehicle door 1 further includes left and right or front and rear longitudinal bones 11 and 12 and an upper and lower upper and lower bones (not shown) both made of extruded aluminum material, and a core material 13 between them. The inner plate 14 and the outer plate 15 made of stainless steel are attached to the inside and the outside of the vehicle. The window opening 2 is formed by these inner and outer plates 14 and 15, and the mouth edge 2 a of the window opening 2 is formed by joint edges 14 a and 15 a in which the inner and outer plates 14 and 15 are doubly joined.
[0022]
The joint edges 14a and 15a are located at substantially the middle position of the window opening 2 in the door thickness direction, and the stepped portion 3 has a vertical hook-shaped surface due to the bending of the inner plate 14 from the joint edges 14a and 15a to the inside of the vehicle. Is formed. The window glass 4 is composed of one sheet, and the elastic pad 6 has a saddle-shaped cross-sectional shape along the corner portion 3a, and its one side 6d extends from the corner portion 3a to the middle position along the joining edge 14a. A seal reservoir 8 is formed between the window glass 4 and the window glass 4. The joint edge 15 a is longer than the joint edge 14 a, and both joint boundaries face the seal reservoir 8. Thus, when the sealing material 5a is applied, filled and solidified in the seal reservoir 8, the boundary portion 46 between the elastic pad 6 and the window glass 4, the boundary portion 36 between the elastic pad 6 and the stepped portion 3, and the joining edge 14a. , 15a can be provided with a seal 5 straddling each of the joint boundaries. The other side 6e of the elastic pad 6 having a saddle-shaped cross section extends from the corner portion 3a to a position flush with the inner side surface of the window glass 4 and is sealed with a corner portion perpendicular to the step glass 3 together with the window glass 4. A reservoir 8 is formed. As a result, when the sealing material 5a is applied, filled and solidified in the seal reservoir 8, both the boundary portion 36 between the elastic pad 6 and the stepped portion 3 and the boundary portion 46 between the elastic pad 6 and the window glass 4 are displayed. The straddling seal 5 can be applied.
[0023]
On the door-end side of the vehicle door 1, the door-end rubber 21 is mounted using flanges 14 b and 15 b obtained by bending the inner and outer plates 14 and 15 to the front end portion of the longitudinal bone 11. A windshield seal member 22 is provided on the door bottom side of the vehicle door 1. The windshield seal member 22 elastically has a base portion 22a in a groove 23 or a flange 24 that is formed integrally with a door bottom portion that is not covered by the inner and outer plates 14 and 15 of the vertical bone 12 that is a door bottom member, and a flange 24. It is fitted and attached. Accordingly, the windshield seal member 22 can be provided on the door butt without a special attachment member, so that the cost is reduced, and the base portion 22a is fitted into the groove 23 or the flange 24 facing the outside of the vehicle. Even if a complete air tight structure is employed in which the seal piece 22b or the like, which is a seal portion of the seal member 22, is in sliding contact with the vehicle outer side member, the windshield seal member 22 has a groove 23 due to the pushing back force that is exerted by sliding contact with the vehicle outer member. Alternatively, since it is pressed against the flange 24, the air tight function can be stably exhibited over a long period of time without falling off due to attachment by fitting.
[0024]
The windshield seal member 22 is press-fitted and fitted so that the base portion 22 a has a bifurcated cross section and straddles the flange 24, and one of the bifurcated cross section portions enters the groove 23, and the groove 23 corresponds to the windshield seal member 22. It is not directly helpful for retention. However, it is possible to attach the base 22a into the groove 23 by press-fitting, or the groove 23 and the flange 24 can be attached together. Note that the base portion 22a of the windshield seal member 22 has a structure exposed to the door butt side, and can be shared by the door butt rubber that contacts the door butt when the vehicle door 1 is opened.
[0025]
The windshield seal member 22 is made of a rubber member, and a spring steel core member 25 having a U-shaped cross section is inserted into the base portion 22a having a bifurcated cross section so as to exert an elastic gripping force. The base 22a is prevented from coming off the flange 24 together with the return piece 22c integrally formed on the inner surface of the base 22a. The core material 25 is a so-called centipede type in which a notch (not shown) is formed by cutting from the tip of both side pieces toward the base, and even if the vehicle door 1 is curved in the vertical direction, the windshield seal member 22 is added thereto. It does not prevent it from being bent along.
[0026]
In the example shown in FIG. 2, the window glass 4 is a multi-layer glass in which a plurality of window glasses 41 and 42 are bonded to each other with a spacer 31, and the elastic pad 6 has a stepped portion 6 e extending from the corner portion 3 a to the vehicle interior side. The seal pool 8 is formed so as to extend to the most open side of the portion 3, that is, between the window glass 41 on the innermost vehicle side and the window glass 42 on the front side, and recedes from the vehicle inner side surface of the window glass 4 to the vehicle outer side. is doing. As a result, even if the window glass 4 is a multi-layer glass and has a large thickness, it is easy to obtain a sufficient capacity for applying the seal 5 by the retraction of the seal reservoir 8 to the outside of the vehicle without being affected by this. . At the same time, the joint edges 14a and 15a of the inner and outer plates 14 and 15 are close to the vehicle outer surface side of the vehicle door 1, more specifically, so that they are flush with each other, and the window glass 4 that is a multilayer glass is fitted together. The step part 3 having a depth dimension sufficient for mounting as described above is obtained. Furthermore, the capacity of the seal reservoir 8 is increased by providing the peripheral wall of the stepped portion 3 with a slight inclination in the depth direction so that the inside of the vehicle is wide and the outside of the vehicle is narrow.
[0027]
Further, in addition to the groove 23 and the flange 24, the groove 26 and the flange 27 are integrally formed in the door bottom of the vertical bone 12, and the door bottom side piece of the bifurcated base portion 22 a of the windshield seal member 22 is press-fitted into the groove 26. Thus, the windshield seal member 22 is further prevented from falling off. Since the other configuration is the same as the example shown in FIG. 1, the same reference numerals are given to the same kind of members, and overlapping illustration and description are omitted.

A partition wall 34 that forms a stepped portion 3 with the shape member 32 by closing a gap between the material 32 and the shape member 32 is provided. In the example shown in FIG. 4, the partition wall 34 is integrally provided by welding or the like on the side of the shape member 32, and the gap between the inner plate 14 is sealed by the seal 5. The other configurations are not particularly different from those described with reference to FIG. 1, and the same type of members are denoted by the same reference numerals, and overlapping illustrations and descriptions are omitted.
[0029]
In the example shown in FIG. 5, in addition to the example shown in FIGS. 3 and 4, a decorative cover 37 is provided on the peripheral wall of the stepped portion 3 through the spacer 39 from the inside of the vehicle, and is screwed by screws or rivets 38. Stopping or riveting is performed, and screwing or riveting is hidden by the seal 5. A pair of flanges 32a facing inward are provided on the door end side of the shape member 32, and the door end rubber 21 is fitted and attached to these flanges 32a. Other configurations are not particularly different from those described with reference to FIGS. 3 and 4, and members of the same kind are denoted by the same reference numerals and overlapping illustrations and descriptions are omitted.
[0030]
The example shown in FIG. 6 shows the case where the single glass window glass 4 in the example shown in FIG. 5 is made of double-glazed glass, and see FIG. 2 or FIG. 5 except that the peripheral wall of the stepped portion 3 is not inclined. Therefore, the same kind of members are denoted by the same reference numerals, and overlapping illustrations and descriptions are omitted.
[0031]
In the example shown in FIG. 7, in the vehicle door 1 having the longitudinal bones 11 and 12 and the upper and lower bones and the inner and outer plates 14 and 15 as shown in FIG. A step 3 is formed on the material 43. The edge 15 a formed by the outer plate 15 extends and is joined to the inner side of the step portion 3 of the shape member 43 so that the joint boundary between the joint edge 15 a and the step portion 3 is the boundary between the elastic pad 6 and the step portion 3. 36, it faces the seal reservoir 8 together with the boundary portion 46 between the elastic pad 6 and the window glass 4, and the seal 5 straddling them is applied.
[0032]
The left and right edges of the inner plate 14 are received by the stepped portion 3 between the shape member 43 and the vertical bones 11 and 12, and the decorative cover 37 covers the receiving portion.

A flange 11a that receives and covers the edge of the plate 14 and a flange 11a that opposes the flange 15b of the outer plate 15 are formed integrally with the vertical bone 11, and a door rubber 21 is fitted to the flanges 15b and 11a. This is different from the example shown in FIG. The other configuration is not particularly different from the example shown in FIG. 7, and the same reference numerals are given to the same kind of members, and redundant description is omitted.
[0034]
The example shown in FIG. 9 has an advantage that the elastic pad 6 is simplified as a flat shape along the vehicle outer surface of the window glass 4, and the window glass 4 can be fixed and sealed with a small thickness. In this case, a seal pool 8 is formed between the outer periphery of the window glass 4 and the step portion 3. The elastic pad 6 cannot be uniquely positioned in the surface direction even if the window glass 4 is applied, but the positioning state is maintained by positioning and bonding in the surface direction. By using the elastic pad 6, the window glass 4 is positioned in the plane direction not only when the window glass 4 is attached to the vehicle door 1 laid sideways but also when the window glass 4 is attached to the vertically oriented vehicle door 1.
