Description

【０００１】
【発明の属する技術分野】
この発明は、鉄道車両等の車両の客室内装パネルの組み立て構造に関するものである。
【０００２】
【従来の技術】
従来、鉄道車両等の車両の客室内装パネルの組み立て構造として、２つの客室内装パネルの側縁部をパネル接続具（いわゆるパネエッジ）を用いて接続することは、一般に行われている。このパネル接続具は、平板状の基部より前方（表面側）に縦壁部が突設されている。この縦壁部の前端には、前記基部と平行に延びる平板状の表面カバー部が連設されている。前記基部及び表面カバー部との間であって前記縦壁部の両側に係合凹部が形成されている。この係合凹部に２つの客室内装パネルの一側縁部が係脱可能に係合されることで、前記両客室内装パネルが接続されるようになっている。
【０００３】
そのようなパネル接続具は、所定の支持剛性を得るために、前記基部が、受け骨部材にねじ止めされている。受け骨部材は、車両の構体に溶接により固設されている。このように受け骨部材にねじ止めされたパネル接続具の係合凹部に、一側縁部が係脱可能に係合されることで、客室内装パネルが取り付けられる。
【０００４】
【発明が解決しようとする課題】
そのような構造では、パネル接続具を受け骨部材にねじ止めすることで支持剛性を確保するようにしているので、受け骨部材を予め車両の構体に溶接により固設しておく必要があった。そのような受け骨部材を構体に溶接により固設するのは、面倒な作業である。よって、コストアップの原因となっている。
【０００５】
そのため、パネル接続具をねじ止めするための受け骨部材をできるだけ廃止し、車両の構体を簡素化してコストダウンを図りたいという要求がある。また、パネル接続具を、客室内装パネルの接続に先立って、前記受け骨部材にねじ止めするのも面倒な作業であった。
【０００６】
本発明はかかる点に鑑みてなされたもので、パネル接続具を受け骨部材にねじ止めすることなく、パネル接続具による客室内装パネルの接続を可能とし、車両の構体にパネル接続具を取り付けるための受け骨部材を溶接により固設する作業を廃止できる車両の客室内装パネルの組み立て構造を提供することを目的とする。
【０００７】
【課題を解決するための手段】
請求項１の発明は、平板状の基部と、該基部より前方に突設された縦壁部と、該縦壁部の前端に連設され前記基部と平行に延びる平板状の表面カバー部とを有し、前記基部及び表面カバー部との間であって前記縦壁部の両側に、客室内装パネルの一側縁部が係脱可能に係合される係合凹部が形成されるパネル接続具を用い、該パネル接続具の各係合凹部に２つの客室内装パネルの一側縁部をそれぞれ挿入することで前記両客室内装パネルを接続する車両の客室内装パネルの組み立て構造であって、前記客室内装パネルの他側縁部は、押さえ部材にて押圧され、該押さえ部材が受け骨部材に取り付けられ、該受け骨部材が車両の構体に溶接により固設され、前記パネル接続具は、それの長手方向が車両の上下方向に一致するように配設されると共に、前記基部に後方に突出する脚部が形成され、車両の構体に対し浮遊状態とされるものである。ここで、前記脚部は、パネル接続具の剛性を高めるために設けられているものであり、その数は１個だけでもよく、複数個でもよい。また、パネル接続具の係合凹部と客室内装パネルの一側縁部との間に接着剤を用い、それらを接着固定することもできる。
【０００８】
請求項１の発明によれば、パネル接続具の基部に後方に突出する脚部が設けられ、パネル接続具が、車両の構体に対し浮遊状態とされている。前記脚部によってパネル接続具自体の剛性が高められて、パネル接続具を受け骨部材（車両の構体）に取り付けないでも、従来受け骨部材にねじ止めされている場合と同様に、接続部分において必要な強度が確保される。また、客室内装パネルの他側縁部が、押さえ部材を介して、受け骨部材に例えばねじにて取り付けられているので、客室内装パネルの一側縁部が浮遊状態のパネル接続具にて接続されているだけであっても、車両の前後方向において、車両の構体への取り付け強度は確保される。
【０００９】
パネル接続具を受け骨部材にねじ止めする必要がないので、パネル接続具をねじ止めするための受け骨部材を廃止することができる。よって、パネル接続具のねじ止めという面倒な作業や車両の構体に対し受け骨部材を溶接により固設する作業の必要がなくなるのに加えて、部品点数の低減、車両の構体全体の簡素化が図れる。
【００１０】
このような請求項１の車両の客室内装パネルの組み立て構造が用いられるのは、請求項２の発明のように、前記客室内装パネルが、客室側部の下側部分である腰部を構成し、厚さが２mm以下の化粧板のみからなるものが望ましい。
【００１３】
請求項３の発明は、請求項１又は２の車両の客室内装パネルの組み立て構造において、前記客室内装パネルの上縁部及び下縁部が、押さえ部材に係止され、該押さえ部材が受け骨部材に取り付けられ、該受け骨部材が車両の構体に溶接により固設されているものである。
【００１４】
請求項３の発明によれば、客室内装パネルの上縁部及び下縁部が、押さえ部材を介して、受け骨部材に例えばねじにて取り付けられている。よって、車両の上下方向において、車両の構体への取り付け強度が確保される。
【００１５】
また、いわゆる小天井に用いる客室内装パネルは、荷物棚を取り付けるなどの理由によりパネル厚さを厚くしたいという要求があるが、そのようにすると、パネルの剛性が高くなり、請求項１〜４の発明と同様の構造とすると、パネル接続具にてうまく接続できなくなるおそれがあるので、そのような場合には、請求項４及び５の発明のように構成することができる。
【００１６】
即ち、請求項４の発明は、平板状の基部と、該基部より前方に突設された縦壁部と、該縦壁部の前端に連設され前記基部と平行に延びる平板状の表面カバー部とを有し、前記基部及び表面カバー部との間であって前記縦壁部の両側に、客室内装パネルの一側縁部が係脱可能に係合される係合凹部が形成されるパネル接続具を用い、該パネル接続具の各係合凹部に２つの客室内装パネルの一側縁部をそれぞれ挿入することで前記両客室内装パネルを接続する車両の客室内装パネルの組み立て構造であって、前記客室内装パネルの他側縁部は、押さえ部材にて押圧され、該押さえ部材が受け骨部材に取り付けられ、該受け骨部材が車両の構体に溶接により固設され、前記客室内装パネルが、表面側から化粧板、芯材及び裏板が順に積層されてなる積層構造を有し、前記一側縁部が、化粧板を残すように厚さを薄くして、前記パネル接続具の係合凹部に挿入され、前記パネル接続具は車両の構体に対し浮遊状態とされるものである。ここで、「化粧板を残すように厚さを薄くして」とは、化粧板のみとする場合は勿論、例えば化粧板が薄い場合等においては、化粧板を含めて芯材の一部も残すようにすることも含まれる。
【００１７】
請求項４の発明によれば、客室内装パネルが、表面側から化粧板、芯材及び裏板が順に積層されてなる積層構造を有する。客室内装パネル自体の厚さは厚いが、パネル接続具にて接続するパネルの一側縁部は、化粧板を残すように厚さが薄くされている。よって、そのパネルの一側縁部が前記パネル接続具の係合凹部に無理なく挿入される。このように、客室内装パネル自体の剛性が高くても、パネル接続具にて接続する部分の剛性を低下させることで、前述した請求項１〜３の発明と同様に、車両の構体に対し浮遊状態のパネル接続具を用いた接続が可能とされる。
【００１８】
請求項５の発明は、請求項４の車両の客室内装パネルの組み立て構造において、前記客室内装パネルが、客室側部と天井部との間に小天井部を構成し、他側縁部が押さえ部材にて押圧され、該押さえ部材が、受け骨部材に取り付けられ、該受け骨部材が、車両の構体に溶接により固設されているものである。
【００１９】
請求項５の発明によれば、客室内装パネルの他側縁部が、押さえ部材を介して、受け骨部材に例えばねじにて取り付けられている。よって、前述した請求項３の発明と同様に、車両の前後方向において、客室内装パネルの、車両の構体への取り付け強度は確保される。
【００２０】
請求項６の発明は、請求項４又は５の車両の客室内装パネルの組み立て構造において、前記客室内装パネルの上縁部及び下縁部が、押さえ部材に係止され、該押さえ部材が受け骨部材に取り付けられ、該受け骨部材が車両の構体に溶接により固設されているものである。
【００２１】
請求項６の発明によれば、客室内装パネルの上縁部及び下縁部が、受け骨部材に例えばねじにて取り付けられている。よって、前述した請求項４の発明と同様に、車両の上下方向において、車両の構体への取り付け強度は確保される。
【００２２】
【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。
【００２３】
図１（ａ）（ｂ）は本発明に係る車両の客室内装パネルの組み立て状態を示し、（ａ）は客室の側面を示す図、（ｂ）は同上面を示す図である。また、図２は図１のII-II線における断面図、図３は本発明に係るパネル接続具の正面図、図４は図１のIV-IV線における断面図、図５は図１のV-V線における断面図、図６は図１のVI-VI線における断面図である。
【００２４】
図１（ａ）に示すように、車両の客室において、客室側部の窓部の下側部分である腰部は、２枚の客室内装パネル１，２の一側縁部（車両の前後方向における一側縁部）を、パネル接続具３（図２参照）を用いて接続して１つのパネル・アッセンブリとして構成されている。この客室内装パネル１，２は、厚さが２mm以下の化粧板（例えばメラミン樹脂）のみからなる。
【００２５】
パネル接続具３は、図３に詳細を示すように、アルミニウム合金の押し出し型材からなり、ほぼ左右対称となっている。パネル接続具３は、車両の上下方向に長い平板状の基部３ａを有し、該基部３ａより前方に縦壁部３ｂが突設されている。この縦壁部３ｂの前端には、前記基部３ａと平行に延びる平板状の表面カバー部３ｃが連設されている。前記基部３ａ及び表面カバー部３ｃとの間であって前記縦壁部３ｂの両側に、客室内装パネル１，２の一側縁部が係脱可能に係合される係合凹部３ｄ，３ｅが形成されている。前記基部３ａの両側縁部には、１対の脚部３ｆ，３ｇが平行に後方に突出するように形成されている。前記１対の脚部３ｆ，３ｇによって、パネル接続具３の剛性が高められる。
【００２６】
前記表面カバー部３ｃの長さは、基部３ａの長さよりもかなり短く、１／３程度とされている。これは、客室側に露出する部分（パネル接続具３）を少なくするためである。
【００２７】
前記基部３ａの、表面カバー部３ｃに対向する面３ｈは、緩やかな傾斜面とされている。これは、客室内装パネル１，２の一側縁部の係合凹部３ｄ，３ｅへの挿入が容易となるようにするためである。また、前記表面カバー部３ｃの、基部３ａに対向する面には、縦壁部３ｂ寄りに凹部３ｋが形成されている。これにより、表面カバー部３ｃが、基部３ａと離れる方向にたわみやすくなり、この点においても、客室内装パネル１，２の一側縁部の係合凹部３ｄ，３ｅへの挿入が容易となるようにされている。
【００２８】
そして、前記パネル接続具３の各係合凹部３ｄ，３ｅには、前記２つの客室内装パネル１，２の一側縁部がそれぞれ挿入されている。これにより、前記両客室内装パネル１，２が接続される。このとき、パネル接続具３は、それの長手方向が車両の上下方向に一致するように配設されている。
【００２９】
前記パネル接続具３は、車両の構体６に対して取り付け固定されることなく、車両の構体６に対し浮遊状態とされている。しかしながら、脚部３ｆ，３ｇを一体に設けることで剛性が高められているので、両客室内装パネル１，２を接続するのに必要な剛性は確保されている。よって、従来の構造において、パネル接続具３を、車両の構体に溶接により固設された受け骨部材にねじ止めする場合と同様に、両パネル１，２の接続部分において必要な強度が確保される。
【００３０】
また、前記客室内装パネル１の他側縁部（車両の前後方向における他側縁部）は、図４に示すように、押さえ部材５にて客室側から押さえられている。４１は戸袋パネルである。なお、客室内装パネル２の他側縁部も同様に押さえられている。
【００３１】
この押さえ部材５は、受け骨部材７の取り付け部７ａに、所定の厚さのレベル調整ライナ１３を介して、固定ねじ８にて取り付け固定されている。この受け骨部材７は、車両の構体６に溶接により固設されている。
【００３２】
前記押さえ部材５は、客室側に露出する断面コ字形状の押さえ部５ａを有し、この押さえ部５ａにおいて、前記固定ねじ８が適用される。この固定ねじ８が適用される部分には樹脂型材が１４が設けられ、該樹脂型材１４によって前記固定ねじ８の頭部が覆い隠され、客室側からは直接に見えないようにされている。
【００３３】
前記客室内装パネル１の上縁部は、図５に示すように、押さえ部材１１の上側係止部１１ａに係止されている。その係止部分は飾り部材１９にて覆われ、客室側から見えないようにされている。押さえ部材１１は、下側部分において受け骨部材９の取り付け部９ａに固定ねじ１０にて、所定の厚さのレベル調整ライナ１５を介して取り付け固定されている。受け骨部材９は、車両の構体６に溶接により固設されている。なお、１２は二重構造のウインドガラスである。
【００３４】
一方、前記客室内装パネル１の下縁部は、図６に示すように、押さえ部材１６の係止部１６ａに係止されている。押さえ部材１６は、台枠４２（床部）から上方に延びる支持部材１７に所定の厚さのレベル調整ライナ１８を介して支持されている。４３は床敷物である。なお、押さえ部材１６は、図示しない部位において車両の構体に固定ねじで取り付け固定されている。
【００３５】
前記客室内装パネル１の上下縁部は、車両の構体側に予め取り付け固定されている押さえ部材１１，１６の係止部１１ａ，１６ａに差し込むことで、係止されるようになっている。
【００３６】
このような構造にすれば、両客室内装パネル１，２の一側縁部を接続するパネル接続具３が、車両の構体６とは離れた浮遊状態であっても、そのほかの他側縁部及び上下縁部を、車両の構体に取り付け固定された押さえ部材５，１１，１６を利用して係止させるようにしているので、客室内装パネル１，２として必要とされる取り付け強度は確保される。よって、パネル接続具３をねじ止めするための受け骨部材を廃止することができ、車両の構体６を簡素化してコストダウンを図る上で有利となる。また、パネル接続具３を、客室内装パネル１，２の接続に先立って、受け骨部材にねじ止めするという面倒な作業も必要なくなり、客室内装パネル１，２の取り付け作業性が向上する。
【００３７】
ところで、客室側部と天井部との間における小天井（１５０mm程度の半径で湾曲している部分）は、荷物棚を取り付けたいという要求がある。そのため、荷物棚の取り付けが可能となるように、前述した客室内装パネル１，２に比べて厚さが厚い客室内装パネル（例えば厚さ７mm程度）を用いることが考えられる。しかしながら、その場合には、前述したものと同様の構造とすると、パネル剛性が高いために、接続部分において接続すべき客室内装パネル間に段差が生じる。よって、パネル接続具による客室内装パネルの接続が困難になる。また、パネル接続具も、前述したパネル接続具３と同様に脚部を有する構造とすると、そのような小天井を構成する客室内装パネルの一側縁部を無理なく接続できるように湾曲した形状としにくい。
【００３８】
そこで、そのような場合には、図１（ｂ）、図５及び図７〜図９に示すように構成することができる。即ち、客室内装パネル２１，２２は、積層構造（厚さ７mm程度）として剛性が高められており、図７に示すように、表面側から化粧板２１ａ，２２ａ（例えばメラミン樹脂:厚さ１．４mm程度）、芯材２１ｂ，２２ｂ（例えば発泡材であるクレゲセル:厚さ５．１mm程度）及び裏板２１ｃ、２２ｃ（例えばアルミニウム合金：厚さ０．５mm程度）が順に積層されてなる。接続される側の一側縁部は、化粧板２１ａ，２２ａのみとして厚さが薄く形成され、前記パネル接続具３Ａの係合凹部３ｄ，３ｅに無理なく挿入されるようになっている。なお、化粧板２１ａ，２２ａのみとされている部分の長さの和Ｌ１は、パネル接続具３の基部の長さＬ２のほぼ３倍とされている。
【００３９】
前記パネル接続具３Ａは、車両の構体に対して接触しておらず浮遊状態とされる点は前記パネル接続具３と同様であるが、脚部３ｆ，３ｇが設けられていない点で、前記パネル接続具３とは異なる。
【００４０】
前記客室内装パネル２１の他側縁部は、図８に示すように、断面Ｌ字形状の押さえ部材２３にて客室側から押圧されている。この押さえ部材２３によって、前記客室内装パネル２１が、所定の厚さのレベル調整ライナ２８と共に、受け骨部材２４に固定ねじ２５を適用することで取り付け固定されている。受け骨部材２４は、図示していないが、車両の構体に溶接により固設されている。また、前記押さえ部材２３によって、客室内装パネル２１の２倍程度の厚さを有し客室内装パネル２１とほぼ直交する位置関係にある仕切りパネル２６も、固定ねじ２５を適用することで、受け骨部材２４に取り付け固定されている。一方、客室内装パネル２２の他側縁部は、別のパネル接続具３Ａを用いて、別の客室内装パネル２７（図１（ｂ）参照）に接続されている。
【００４１】
さらに、前記客室内装パネル２１の上縁部は、図９に示すように、受け骨部材３１に固定ねじ３２にて所定の厚さのレベル調整ライナー３３を介して取り付け固定されている。一方、下縁部は、図５に示すように、受け骨部材３４に固定ねじ３５にて直接に取り付けられ、その部分は飾り部材３６にて覆われている。受け骨部材３１，３４は、車両の構体６に溶接により固設されている。なお、図９において、３６は照明のための灯具である。
【００４２】
このような構造においては、積層構造の客室内装パネル２１，２２の一側縁部を化粧板２１ａ，２２ａのみとしてその部分の剛性を低下させて、パネル接続のための適切な剛性としている。そして、適切な剛性を有するパネル接続具３Ａを用いて接続するようにしているので、積層構造の客室内装パネル２１，２２の一側縁部の接続は無理なく行われる。
【００４３】
よって、前述した客室内装パネル１，２の場合と同様に、パネル接続具３Ａを受け骨部材にねじ止めすることなく、パネル接続具３Ａによる客室内装パネル２１，２２の接続が可能となる。そのため、前述した実施の形態と同様に、車両の構体６にパネル接続具を取り付けるための受け骨部材を設ける必要がなくなるので、そのような受け骨部材を車両の構体に溶接により固設する作業を廃止することができる。
【００４４】
また、前記客室内装パネル２１は、前記一側縁部を除く他の部分については、前述したように積層構造で、厚さが７mm程度であるので、化粧板のみから構成される場合とは異なり、パネルの剛性が高く、荷物棚などを取り付けることも可能となる。
【００４５】
【発明の効果】
本発明は、以上に説明したような形態で実施され、以下に述べるような効果を奏する。
【００４６】
請求項１の発明は、パネル接続具の基部に後方に突出する脚部を設け、パネル接続具の各係合凹部に２つの客室内装パネルの一側縁部をそれぞれ挿入することで前記両客室内装パネルを接続すると共に、前記パネル接続具を、車両の構体に対し浮遊状態としているので、パネル接続具自体の剛性を高めて、車両の構体に取り付けることなく、必要な接続強度を確保することができる。また、客室内装パネルの他側縁部を、押さえ部材を介して、車両の構体の受け骨部材に取り付けるようにしているので、車両の前後方向において車両の構体への取り付け強度を確保することができる。
よって、パネル接続具を、従来のように、車両の構体の受け骨部材にねじ止めしないので、そのねじ止めのための受け骨部材が必要なくなり、車両の構体に受け骨部材を溶接により固設する必要がなくなる。このように、パネル接続具をねじ止めする受け骨部材を廃止することで、部品点数を低減して、車両の構体の簡素化を図ることができ、コストダウンを図る上で有利となる。
【００４７】
請求項２の発明は、客室内装パネルが、客室側部の下側部分である腰部を構成し、厚さが２mm以下の化粧板のみからなるので、請求項１の発明の効果を効果的に発揮させることができる。
【００４８】
請求項３の発明は、客室内装パネルの上下縁部を、押さえ部材にて押さえるようにしているので、車両の上下方向において、車両の構体への取り付け強度を確保することができる。
【００４９】
請求項４の発明は、客室内装パネルが、表面側から化粧板、芯材及び裏板が順に積層されてなる積層構造を有し、前記一側縁部を、化粧板を残すように厚さを薄くして、前記パネル接続具の係合凹部に挿入して接続するようにしているので、客室内装パネルの厚さが厚く、パネル剛性が高い場合であっても、パネル接続具にて接続する部分の剛性を低下させることで、前述した請求項１の発明と同様に、車両の構体に対し浮遊状態のパネル接続具を用いた接続が可能となる。また、客室内装パネルの厚さが厚いので、パネル剛性が高くなり、荷物棚を取り付けることも可能である。
【００５０】
請求項５の発明は、客室内装パネルの他側縁部を、請求項６の発明は、上下縁部を、それぞれ、車両の構体の受け骨部材に取り付けるようにしているので、車両の前後方向及び上下方向において車両の構体への取り付け強度を確保することができる。

BACKGROUND OF THE INVENTION
The present invention relates to an assembly structure of a passenger compartment panel of a vehicle such as a railway vehicle.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as an assembly structure of a passenger compartment panel of a vehicle such as a railway vehicle, connecting the side edges of two passenger compartment panels using a panel connector (so-called panel edge) is generally performed. This panel connector has a vertical wall projecting forward (front side) from a flat base. A flat surface cover portion extending in parallel with the base portion is connected to the front end of the vertical wall portion. Engaging recesses are formed between the base portion and the surface cover portion and on both sides of the vertical wall portion. The two cabin interior panels are connected to each other by detachably engaging one side edge of the two cabin interior panels with the engaging recess.
[0003]
In such a panel connector, the base is screwed to the receiving bone member in order to obtain a predetermined support rigidity. The receiving bone member is fixed to the vehicle structure by welding. Thus, a cabin interior panel is attached by engaging one side edge part with the engagement recessed part of the panel connection tool screwed by the receiving bone member so that engagement / disengagement is possible.
[0004]
[Problems to be solved by the invention]
In such a structure, since the support rigidity is secured by screwing the panel connector to the bone member, it is necessary to fix the receiving bone member to the vehicle structure in advance by welding. . It is a troublesome work to fix such a receiving bone member to the structure by welding. Therefore, it is a cause of cost increase.
[0005]
For this reason, there is a demand to eliminate as much as possible the receiving bone member for screwing the panel connector, simplify the structure of the vehicle, and reduce the cost. In addition, it is a troublesome work to screw the panel connector to the receiving bone member prior to connecting the cabin interior panel.
[0006]
SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and enables the connection of the cabin interior panel by the panel connector without attaching the panel connector to the bone member and attaching the panel connector to the vehicle structure. It is an object of the present invention to provide an assembly structure of a vehicle interior panel that can eliminate the work of fixing the receiving frame member by welding.
[0007]
[Means for Solving the Problems]
The invention of claim 1 is a flat base, a vertical wall projecting forward from the base, and a flat surface cover extending in front of the vertical wall and extending parallel to the base. A panel connection in which an engagement recess is formed between the base portion and the surface cover portion and on both sides of the vertical wall portion so that one side edge portion of the cabin interior panel is detachably engaged. An assembly structure of a vehicle interior panel that connects the cabin interior panels by inserting one side edge of each of the 2 cabin interior panels into each engagement recess of the panel connector, The other side edge portion of the cabin interior panel is pressed by a pressing member, the pressing member is attached to a receiving bone member, the receiving bone member is fixed to a vehicle structure by welding, and the panel connector is When arranged so that its longitudinal direction coincides with the vertical direction of the vehicle The leg portion protruding rearward is formed in the base portion, it is intended to be a floating state with respect to structure of the vehicle. Here, the said leg part is provided in order to improve the rigidity of a panel connector, The number may be only 1 piece and multiple pieces may be sufficient as it. Moreover, an adhesive agent can be used between the engagement recessed part of a panel connector, and the one side edge part of a passenger compartment interior panel, and they can also be adhesively fixed.
[0008]
According to invention of Claim 1, the leg part which protrudes back is provided in the base part of the panel connector, and the panel connector is made into the floating state with respect to the structure of a vehicle. The leg portion increases the rigidity of the panel connector itself, and even if the panel connector is not attached to the bone member (vehicle structure), the connection portion is similar to the conventional case where it is screwed to the bone member. Necessary strength is ensured. In addition, since the other side edge of the cabin interior panel is attached to the receiving frame member, for example, with a screw via the pressing member, one side edge of the cabin interior panel is connected with a floating panel connector. Even if it is only done, the mounting strength to the vehicle structure is ensured in the longitudinal direction of the vehicle.
[0009]
Since it is not necessary to screw the panel connector to the receiving bone member, the receiving bone member for screwing the panel connecting member can be eliminated. Therefore, in addition to the troublesome work of screwing the panel connector and the work of fixing the receiving bone member to the vehicle structure by welding, the number of parts can be reduced and the overall structure of the vehicle can be simplified. I can plan.
[0010]
The assembly structure of the vehicle interior panel of the vehicle according to claim 1 is used as in the invention of claim 2, wherein the cabin interior panel constitutes a waist part which is a lower portion of the cabin side part, What consists only of a decorative board whose thickness is 2 mm or less is desirable.
[0013]
According to a third aspect of the present invention, in the assembly structure of the vehicle interior panel of the vehicle according to claim 1 or 2 , an upper edge portion and a lower edge portion of the cabin interior panel are locked to a pressing member, and the pressing member is a receiving bone. It is attached to the member, and the receiving bone member is fixed to the structure of the vehicle by welding.
[0014]
According to invention of Claim 3 , the upper edge part and lower edge part of a cabin interior panel are attached to the receiving bone member with the screw, for example via the pressing member. Therefore, the mounting strength to the vehicle structure is ensured in the vertical direction of the vehicle.
[0015]
In addition, the interior panel used for the so-called small ceiling has a demand to increase the panel thickness for reasons such as attaching a luggage shelf. However, if so, the rigidity of the panel is increased. If the structure is the same as that of the invention, there is a possibility that the panel connector cannot be connected well. In such a case, the invention can be configured as in the inventions of claims 4 and 5 .

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0023]
1A and 1B show an assembled state of a vehicle interior panel of a vehicle according to the present invention, FIG. 1A shows a side view of the passenger cabin, and FIG. 1B shows a top view of the same. 2 is a sectional view taken along line II-II in FIG. 1, FIG. 3 is a front view of the panel connector according to the present invention, FIG. 4 is a sectional view taken along line IV-IV in FIG. 6 is a cross-sectional view taken along the line VI-VI in FIG.
[0024]
As shown in FIG. 1 (a), in the passenger compartment of a vehicle, the waist portion, which is the lower portion of the window portion on the passenger compartment side, is one side edge portion (in the front-rear direction of the vehicle) One side edge portion) is connected using a panel connector 3 (see FIG. 2) to constitute one panel assembly. The cabin interior panels 1 and 2 are composed only of a decorative board (for example, melamine resin) having a thickness of 2 mm or less.
[0025]
As shown in detail in FIG. 3, the panel connector 3 is made of an extruded material of an aluminum alloy and is substantially symmetrical. The panel connector 3 has a flat plate-like base portion 3a that is long in the vertical direction of the vehicle, and a vertical wall portion 3b that protrudes forward from the base portion 3a. A flat surface cover 3c extending in parallel with the base 3a is connected to the front end of the vertical wall 3b. Engaging recesses 3d and 3e between the base portion 3a and the surface cover portion 3c and on both sides of the vertical wall portion 3b are engaged with detachably engaged side edges of the cabin interior panels 1 and 2. Is formed. A pair of leg portions 3f and 3g are formed on both side edges of the base portion 3a so as to protrude rearward in parallel. The rigidity of the panel connector 3 is enhanced by the pair of legs 3f and 3g.
[0026]
The length of the surface cover portion 3c is considerably shorter than the length of the base portion 3a, and is about 1/3. This is to reduce the portion exposed to the passenger compartment (panel connector 3).
[0027]
A surface 3h of the base portion 3a facing the surface cover portion 3c is a gently inclined surface. This is to facilitate the insertion of the one side edge of the cabin interior panels 1 and 2 into the engagement recesses 3d and 3e. Further, a concave portion 3k is formed on the surface of the surface cover portion 3c facing the base portion 3a near the vertical wall portion 3b. As a result, the surface cover portion 3c is easily deflected in the direction away from the base portion 3a, and also in this respect, insertion into the engagement recesses 3d and 3e at the one side edge portion of the cabin interior panels 1 and 2 is facilitated. Has been.
[0028]
In each of the engaging recesses 3d and 3e of the panel connector 3, one side edge of the two cabin interior panels 1 and 2 is inserted. As a result, the cabin interior panels 1 and 2 are connected. At this time, the panel connector 3 is disposed such that the longitudinal direction thereof coincides with the vertical direction of the vehicle.
[0029]
The panel connector 3 is in a floating state with respect to the vehicle structure 6 without being fixed to the vehicle structure 6. However, since the rigidity is enhanced by integrally providing the leg portions 3f and 3g, the rigidity necessary for connecting the cabin interior panels 1 and 2 is secured. Therefore, in the conventional structure, the required strength is ensured at the connecting portion of both panels 1 and 2 in the same manner as when the panel connector 3 is screwed to the receiving bone member fixed to the vehicle structure by welding. The
[0030]
Moreover, the other side edge part (other side edge part in the front-back direction of the vehicle) of the cabin interior panel 1 is pressed from the cabin side by a pressing member 5 as shown in FIG. 41 is a door pocket panel. In addition, the other side edge part of the guest room interior panel 2 is pressed down similarly.
[0031]
The pressing member 5 is fixedly attached to the attachment portion 7a of the receiving bone member 7 with a fixing screw 8 via a level adjusting liner 13 having a predetermined thickness. The receiving bone member 7 is fixed to the vehicle structure 6 by welding.
[0032]
The pressing member 5 has a pressing portion 5a having a U-shaped cross section exposed to the passenger compartment side, and the fixing screw 8 is applied to the pressing portion 5a. A resin mold material 14 is provided at a portion to which the fixing screw 8 is applied, and the head of the fixing screw 8 is covered by the resin mold material 14 so that it cannot be directly seen from the passenger compartment side.
[0033]
As shown in FIG. 5, the upper edge portion of the cabin interior panel 1 is locked to the upper locking portion 11 a of the pressing member 11. The locking portion is covered with a decorative member 19 so that it cannot be seen from the passenger cabin side. The holding member 11 is attached and fixed to the attachment portion 9a of the receiving bone member 9 at a lower portion by a fixing screw 10 via a level adjustment liner 15 having a predetermined thickness. The receiving bone member 9 is fixed to the vehicle structure 6 by welding. Reference numeral 12 denotes a double-structured window glass.
[0034]
On the other hand, the lower edge portion of the cabin interior panel 1 is locked to the locking portion 16a of the pressing member 16 as shown in FIG. The pressing member 16 is supported by a support member 17 extending upward from the underframe 42 (floor portion) via a level adjustment liner 18 having a predetermined thickness. 43 is a floor covering. The pressing member 16 is attached and fixed to a vehicle structure with a fixing screw at a portion (not shown).
[0035]
The upper and lower edge portions of the cabin interior panel 1 are locked by being inserted into the locking portions 11a and 16a of the pressing members 11 and 16 that are mounted and fixed in advance on the vehicle structure side.
[0036]
With such a structure, even if the panel connector 3 that connects one side edge of the cabin interior panels 1 and 2 is in a floating state separated from the vehicle structure 6, the other side edge In addition, since the upper and lower edges are locked using the pressing members 5, 11, and 16 that are fixedly attached to the vehicle structure, the mounting strength required for the cabin interior panels 1 and 2 is secured. The Therefore, the receiving bone member for screwing the panel connector 3 can be eliminated, which is advantageous in simplifying the vehicle structure 6 and reducing the cost. Further, the troublesome work of screwing the panel connector 3 to the receiving bone member prior to the connection of the cabin interior panels 1 and 2 is not required, and the installation workability of the cabin interior panels 1 and 2 is improved.
[0037]
By the way, a small ceiling (portion curved with a radius of about 150 mm) between the cabin side and the ceiling is required to attach a luggage shelf. Therefore, it is conceivable to use a cabin interior panel (for example, about 7 mm thick) that is thicker than the cabin interior panels 1 and 2 described above so that a luggage shelf can be attached. However, in that case, if the structure is the same as that described above, the panel rigidity is high, and therefore a step is generated between the cabin interior panels to be connected at the connection portion. Therefore, it becomes difficult to connect the cabin interior panel using the panel connector. Further, when the panel connector has a structure having legs as in the panel connector 3 described above, the curved shape is formed so that one side edge of the cabin interior panel constituting such a small ceiling can be connected without difficulty. Hard to do.
[0038]
Therefore, in such a case, it can be configured as shown in FIG. 1B, FIG. 5, and FIGS. That is, the cabin interior panels 21 and 22 have a laminated structure (thickness of about 7 mm) and have increased rigidity. As shown in FIG. 7, the decorative plates 21a and 22a (for example, melamine resin: thickness 1.. 4 mm), core materials 21b and 22b (for example, cregue cell as foam material: thickness of about 5.1 mm) and back plates 21c and 22c (for example, aluminum alloy: thickness of about 0.5 mm) are sequentially laminated. One side edge portion of the side to be connected is formed thin as only the decorative plates 21a and 22a, and is easily inserted into the engaging recesses 3d and 3e of the panel connector 3A. The sum L1 of the lengths of only the decorative plates 21a and 22a is approximately three times the base length L2 of the panel connector 3.
[0039]
The panel connector 3A is the same as the panel connector 3 in that the panel connector 3A is not in contact with the vehicle structure and is in a floating state, but the legs 3f and 3g are not provided. Different from the panel connector 3.
[0040]
As shown in FIG. 8, the other side edge of the cabin interior panel 21 is pressed from the cabin side by a pressing member 23 having an L-shaped cross section. The presser member 23 attaches and fixes the cabin interior panel 21 together with a level adjusting liner 28 having a predetermined thickness by applying a fixing screw 25 to the receiving bone member 24. Although not shown, the receiving bone member 24 is fixed to the vehicle structure by welding. Further, the partition panel 26 having a thickness approximately twice the thickness of the cabin interior panel 21 by the pressing member 23 and being substantially orthogonal to the cabin interior panel 21 is also provided with a receiving bone by applying the fixing screw 25. It is fixedly attached to the member 24. On the other hand, the other side edge of the guest room interior panel 22 is connected to another guest room interior panel 27 (see FIG. 1B) using another panel connector 3A.
[0041]
Further, as shown in FIG. 9, the upper edge portion of the cabin interior panel 21 is fixedly attached to the receiving bone member 31 with a fixing screw 32 via a level adjustment liner 33 having a predetermined thickness. On the other hand, as shown in FIG. 5, the lower edge portion is directly attached to the receiving bone member 34 with a fixing screw 35, and the portion is covered with a decorative member 36. The receiving bone members 31 and 34 are fixed to the vehicle structure 6 by welding. In FIG. 9, reference numeral 36 denotes a lamp for illumination.
[0042]
In such a structure, one side edge part of the interior panel 21 and 22 of a laminated structure is made into only the decorative boards 21a and 22a, and the rigidity of the part is reduced and it is set as the appropriate rigidity for panel connection. And since it connects using the panel connector 3A which has appropriate rigidity, the connection of the one side edge part of the passenger compartment interior panels 21 and 22 of a laminated structure is performed without difficulty.
[0043]
Therefore, as in the case of the cabin interior panels 1 and 2 described above, the cabin interior panels 21 and 22 can be connected by the panel connector 3A without screwing the panel connector 3A to the bone member. Therefore, as in the above-described embodiment, there is no need to provide a rib member for attaching the panel connector to the vehicle structure 6, so that such a rib member is fixed to the vehicle structure by welding. Can be abolished.
[0044]
The cabin interior panel 21 has a laminated structure as described above, except for the one side edge portion, and has a thickness of about 7 mm. And the rigidity of the panel is high, and it becomes possible to attach a luggage shelf.
[0045]
【The invention's effect】
The present invention is implemented in the form as described above, and has the following effects.
[0046]
According to the first aspect of the present invention, a leg portion that protrudes rearward is provided at the base portion of the panel connector, and one side edge portion of each of the two cabin interior panels is inserted into each of the engagement recess portions of the panel connector. While connecting the interior panel, the panel connector is in a floating state with respect to the vehicle structure, so that the rigidity of the panel connector itself is increased and the necessary connection strength is secured without being attached to the vehicle structure. Can do. In addition, since the other side edge portion of the cabin interior panel is attached to the receiving frame member of the vehicle structure via the pressing member, it is possible to secure the attachment strength to the vehicle structure in the front-rear direction of the vehicle. it can.
Therefore, since the panel connector is not screwed to the receiving frame member of the vehicle structure as in the prior art, there is no need for the receiving bone member for screwing, and the receiving frame member is fixed to the vehicle structure by welding. There is no need to do it. In this way, by eliminating the receiving bone member for screwing the panel connector , the number of parts can be reduced, the vehicle structure can be simplified, and this is advantageous for cost reduction.
[0047]
In the invention of claim 2, since the cabin interior panel constitutes the waist part which is the lower part of the cabin side part and consists only of a decorative board having a thickness of 2 mm or less, the effect of the invention of claim 1 is effectively obtained. It can be demonstrated.
[0048]
In the invention of claim 3 , since the upper and lower edges of the cabin interior panel are pressed by the pressing member, it is possible to secure the mounting strength to the vehicle structure in the vertical direction of the vehicle.
[0049]
According to a fourth aspect of the present invention, the cabin interior panel has a laminated structure in which a decorative plate, a core material, and a back plate are sequentially laminated from the surface side, and the one side edge portion is thick so as to leave the decorative plate. Since the thickness of the cabin interior panel is thick and the panel rigidity is high, the connection is made with the panel connector. By reducing the rigidity of the portion to be connected, the connection using the floating panel connector can be made to the vehicle structure as in the first aspect of the invention. In addition, since the cabin interior panel is thick, the panel rigidity is increased and a luggage rack can be attached.
