Description

【0001】
【発明の属する技術分野】
本発明は車両のウインドウモールディングまたはドリップモールディングとして用いられるモールディングおよびその製造方法に関するものである。
【0002】
【従来の技術】
図8は車両の一部の斜視図である。図中、1は車体パネルで、センタールーフパネル1a、サイドルーフパネル1b、ピラーパネル1cおよびロアパネル1dが一体化した構造になっている。車体パネル1には窓(フロントウインドウ)2が設けられており、その窓板3と車体パネル1との間にウインドウモールディング4が取付けられている。
【0003】
車両にはサイド部Sにおけるピラーパネル1cが窓板3より高くなっているものがあり、このような車両に取付けられるウインドウモールディング4として、サイド部Sで集水用のせきが形成され、コーナー部C付近で変化してアッパー部Uでせきがなくなるものが使用されている。
【0004】
従来このようなウインドウモールディング4として、サイド部Sからアッパー部Uにかけて窓板3に取付けられ、全長にわたって同一横断面形状のウインドウモールディング材からサイド部Sで一部が切除される第1部材と、サイド部Sにおいてせきを形成し、アッパー部Uでは一部切除して車体パネル1側に取付けられる第2部材とが脚部で一体的に結合されたモールディングが提案されている(実公平6−18806号)。
【0005】
しかしながら、このモールディングはコーナー部C付近を境として、サイド部Sで第1部材の一部を切除し、アッパー部Uで第2部材の一部を切除し、サイド部Sで両者を重ねてせきを形成するように取付けて使用するため、取付作業に手間がかかるとともに、切断位置のばらつき等により第1および第2部材の組合せが不一致となり、結合部で変形や間隙が発生し、またコーナー部C付近で不連続となり外観を害するなどの問題点がある。
【0006】
また窓2のサイド部Sからドリップ溝5に沿って伸びるドリップモールディング6に同様の形状のモールディングが用いられる場合があるが、前記と同様の問題点がある。
【0007】
【発明が解決しようとする課題】
本発明の課題は、製造および取付が容易で、サイド部においてせきを形成するとともに、コーナー部付近で変化してアッパー部またはドリップ溝部では実質的なフラッシュ面を形成することができ、かつ全長にわたって連続した優れた外観を有するモールディング、ならびにその効率的な製造方法を提案することである。
【0008】
【課題を解決するための手段】
本発明は次のモールディングおよびその製造方法である。
(1) 車両窓のサイド部において窓板と車体パネル間の間隙に沿って取付けられ、コーナー部付近からアッパー部における窓板と車体パネルの間隙またはドリップ溝に沿って取付けられるように伸びるモールディングであって、
窓板またはドリップ溝側に取付けられる第1部材と、車体パネル側に取付けられる第2部材とが、それぞれ車両窓のサイド部からコーナー部を経てアッパー部またはドリップ溝まで連続して形成され、

第1部材送出路に連通する第2部材押出路に樹脂を供給して、車体パネルと弾接する弾性リップを形成し、かつ第1可動型により横断面形状を変化させることにより、車体パネルの車外側に位置する頭部から車体パネルの高さの変化に対応して変化して高さの異なる脚部が車体パネルに対向して配置されるように伸びてサイド部でせきを形成するとともに、コーナー部付近で変化してアッパー部またはドリップ溝部では第1部材の頭部とフラッシュ面を形成する構造を有する第2部材を連続して押出成形して、第2部材の脚部の下側を第1部材の脚部と連結するように一体成形し、
第1部材の脚部と第2部材の脚部とを、サイド部からコーナー部を経てアッパー部またはドリップ溝部に至る長手方向のほぼ全長にわたって重ねた状態で溶着一体化して接合部を形成することを特徴とするモールディングの製造方法。

(13) 第1可動型のオリフィスを横切るように第2可動型を移動させて、第2部材の頭部を変形させるようにした上記(9)ないし(12)のいずれかに記載の方法。
【0009】
本発明において、「樹脂」は合成樹脂およびゴムを含む意味に用いられる。また「コーナー部付近」はコーナー部またはその付近を意味し、さらに「ドリップモールディング」は「ルーフモールディング」と言うこともある。本発明のモールディングが取付けられる車両は、窓(フロントウインドウ)のサイド部における車体パネル(フロントピラーパネル)が窓板よりも車外側に突出して高くなっているものである。
【0010】
本発明のモールディングは、車両窓のサイド部において窓板と車体パネル(ピラーパネル)間の間隙に沿って取付けられ、コーナー部付近からアッパー部における窓板と車体パネル(センターパネル)との間隙、またはドリップ溝に沿って取付けられるように伸びるモールディングであり、ウインドウモールディングと呼ばれるもの、ならびにドリップモールディングと呼ばれるものを含む。
【0011】
上記モールディングは窓板またはドリップ溝側に取付けられる第1部材と、車体パネル側に取付けられる第2部材とから構成され、第1部材は窓板またはドリップ溝の車外側に位置する頭部から実質的に同じ高さの脚部が前記間隙に挿入されるように伸びる構造を有する。
第2部材は車体パネルの車外側に位置する頭部から車体パネルの高さの変化に対応して変化し高さの異なる脚部が前記車体パネルに対向して配置されるように伸びて、サイド部でせきを形成する構造を有する。第1部材と第2部材は、実質的に同じ高さの第1部材の脚部と高さの異なる第2部材の脚部とが下側で連結するように一体成形された押出成形材からなる。
【0012】
本発明のモールディングは上記のような第2部材を一体化部分を支点として第1部材と重ね、第1部材の脚部と第2部材の脚部とが、サイド部からコーナー部を経てアッパー部またはドリップ溝部に至る長手方向のほぼ全長にわたって重なった状態で溶着一体化して接合部が形成されており、この状態で脚部を窓板またはドリップ溝と車体パネルの間隙に挿入して取付け、使用される。この場合第2部材の少なくともサイド部におけるせきの背面に固着材を設けて車体パネルに固着するのが好ましい。
【0013】
使用状態においては、サイド部において第2部材によりせきが形成されているため、窓板上を流れる雨水(水滴)はワイパーによって掻寄せられてせきに集められ、せきに沿って流れるため、第2部材又はピラーパネルを越えて(横切って)サイドウインドウへの横流れが防止される。第2部材は車体パネルの高さの変化に対応して、好ましくはコーナー部付近で変化し、アッパー部またはドリップ溝部では第1部材の頭部と実質的にフラッシュ面を形成し、空気抵抗を小さくする。
【0014】
本発明のモールディングは第1部材と第2部材から構成されるため、それぞれの部材に別の機能および装飾性を持たせることができ、別部材の複合機能および複合美が得られる。すなわち第1部材は窓板またはドリップ溝への取付および装飾部材として、実質的に同一の形状および意匠に仕上げることができる。そして第2部材はサイド部におけるせき形成と、全域にわたる車体パネルへの取付および装飾部材として、第1部材とは独立した長手方向に変化する形状および意匠に仕上げることができる。
【0015】
本発明のモールディングは第1および第2部材がいずれも、サイド部からコーナー部を経てアッパー部またはドリップ溝部に至る長手方向のほぼ全長にわたって連続して設けられ、脚部における一体化部分を支点として曲げて互いに重ね、第1部材の脚部と第2部材の脚部とが、サイド部からコーナー部を経てアッパー部またはドリップ溝部に至る長手方向のほぼ全長にわたって重なった状態で溶着一体化して接合部が形成されており、この状態で使用されるため、従来のもののように切除作業や切除のばらつきによる不適合、ならびに不連続による外観不良などが防止され、優れた外観が得られる。
【0016】
第1部材はサイド部からコーナー部を経てアッパー部またはドリップ溝部に至る長手方向のほぼ全長にわたって実質的に同一の横断面形状を有するものが一般に使用されるが、部分的に異なる横断面形状を有していてもよく、例えばコーナー部付近では曲げやすいように部分的に薄肉部分を形成して横断面形状を変化させていてもよい。
【0017】
第2部材は頭部が少なくともサイド部で窓板側に庇状部を有し、コーナー部付近で脚部の高さが低くなって、アッパー部またはドリップ溝部では第1部材の頭部と重なるように構成することにより、サイド部で雨水のせき止め効果が高くなり、優れた機能性、装飾性、作業性が得られる。
【0018】
第2部材の庇状部の突出長さが長いと車両走行中の風切音が大きくなり、また手等が触れて車体パネルから離れる方向に力が作用したときに窓板側に倒れやすくなるが、せき部の高さを高くすると庇状部の突出長さが短くても雨水のせき止め効果が得られるので、風切音を小さくしかつ倒れにくくすることができる。この場合でも第1部材が取付性と装飾性を負担するため、第2部材の庇状部を任意の突出長さとして、第1部材とは異なる機能および装飾性を持たせることができる。
【0019】
第2部材の頭部はサイド部からコーナー部を経てアッパー部またはドリップ溝部に至る長手方向のほぼ全長にわたって実質的に同一の横断面形状に形成してもよいが、場合によってはサイド部において形成された庇状部を少なくともコーナー部付近で除去等により無くすることができ、これにより車両の走行中にせきに沿って流れる空気流が遮られることがなく前記除去等の部分を通過するので風切音が小さくなる。
【0020】
第1部材および第2部材は押出成形により一体成形されたものであってもよく、また第1部材は予め所定断面形状に形成された長尺材例えば金属ストリップやこれを折り曲げて所定の異形横断面形状に形成したもの、あるいはアルミニウム合金や樹脂の押出材等を用い、これを押出成形型に供給して押出成形により第2部材と一体化したものでもよい。
【0021】
上記のモールディングは、押出成形型に形成された第1部材送出路を通して長手方向に沿って第1部材を送り出し、押出成形型の第1部材送出路に連通する第2部材押出路に樹脂を供給し、第1可動型により押出路の横断面形状を変化させながら、第2部材を成形して第1部材と一体化させることにより効率よく製造することができる。
【0022】
この場合、第1部材送出路に予め長尺材に成形された第1部材を通して第2部材を押出成形により一体化して形成してモールディングを製造してもよく、また第1部材送出路(第1オリフィス)に樹脂を供給して第1部材を押出成形し、第2部材押出路(第2オリフィス)で押出成形される第2部材と一体化してモールディングを製造してもよい。
【0023】
第2部材の頭部が一定横断面形状のモールディングは、第2部材押出路の第2オリフィスを横切るように第1可動型を移動させて、第1可動型のオリフィスから樹脂を押出すとともに第2部材の脚部の長さを変えながら頭部を形成し、第1部材と一体化することにより製造することができる。また第2部材の頭部の横断面形状が変化するモールディングは、第1可動型のオリフィスを横切るように第2可動型を移動させて、第2部材の頭部の横断面形状を変化させることにより製造することができる。
【0024】
【発明の効果】
本発明のモールディングは、サイド部からコーナー部を経てアッパー部またはドリップ溝部に至るほぼ全域にわたって、窓板またはドリップ溝側に連続して取付けられる第1部材と、車体パネル側に連続して取付けられる高さの異なる第2部材とを有し、第1部材と第2部材は、実質的に同じ高さの第1部材の脚部と高さの異なる第2部材の脚部とが下側で連結するように一体成形された押出成形材からなり、第1部材の脚部と第2部材の脚部とが、サイド部からコーナー部を経てアッパー部またはドリップ溝部に至る長手方向のほぼ全長にわたって重なった状態で溶着一体化して接合部が形成されているので、製造および取付が容易で、サイド部において第2部材でせきを形成するとともに、コーナー部付近で変化してアッパー部またはドリップ溝部では第1部材の頭部と実質的にフラッシュ面を形成することができ、かつ全長にわたって連続した優れた外観を有するモールディングが得られる。また重なった状態で溶着一体化して接合部が形成されている状態で脚部を窓板と車体パネルの間隙に挿入でき、弾発係止片および弾性リップを係合させてウインドウモールディングを仮固定した状態で接着剤を硬化させて組付けることができるので、取付けも容易である。
【0025】
第1部材がサイド部からコーナー部を経てアッパー部またはドリップ溝部に至る長手方向のほぼ全長にわたって実質的に同一の横断面形状を有するモールディングは、全体に均一な取付安定性と装飾性が得られる。
【0026】
第2部材は頭部が少なくともサイド部で窓板側に庇状部を有し、コーナー部付近で脚部の高さが低くなって、アッパー部またはドリップ溝部では第1部材の頭部と重なっているものは、雨水のせき止め効果およびフラッシュ面の形成効果が大きくなる。
【0027】
第2部材の頭部がサイド部からコーナー部を経てアッパー部またはドリップ溝部に至る長手方向のほぼ全長にわたって実質的に同一の横断面形状を有するものは、均一な外観を与える。
第2部材の頭部にサイド部において庇状部が形成され、この庇状部が少なくともコーナー部付近でなくなっているものは車両走行中の風切音が小さくなる。
【0028】
本発明のモールディングの製造方法は、押出成形型に形成された第1部材送出路を通して第1部材を連続して送り出し、第1部材送出路に連通する第2部材押出路(第2オリフィス)に樹脂を供給し、第1可動型を移動させることにより第2オリフィスの横断面形状を変化させながら、第2部材を連続して成形するとともに、第1部材の脚部と連結するように一体成形し、第1部材の脚部と第2部材の脚部とを、サイド部からコーナー部を経てアッパー部またはドリップ溝部に至る長手方向のほぼ全長にわたって重ねた状態で溶着一体化して接合部を形成するため、上記のようなモールディングを効率よく製造することができる。
【0029】
第1部材送出路に予め成形された第1部材を通して第2部材と一体化することにより、予め所定横断面形状の長尺材に形成された第1部材に押出成形により第2部材を形成したモールディングを効率よく製造することができる。
また第1部材送出路(第1オリフィス)に樹脂を供給して第1部材を押出成形し、第2部材と一体化することにより、第1および第2部材が押出成形品からなるモールディングを効率よく製造することができる。
【0030】
第2部材押出路の第2オリフィスを横切るように第1可動型を移動させて第2部材の脚部の長さを変えながら頭部を形成し、第1部材と一体化することにより、第2部材の頭部が同形状で脚部の高さが変化するモールディングを効率よく製造することができる。
また第1可動型のオリフィスを横切るように第2可動型を移動させることにより、第2部材の頭部の横断面形状が変化するモールディングを効率よく製造することができる。
【0031】
【発明の実施の形態】
以下、本発明の実施の形態を図面により説明する。
図1は本発明の実施形態のモールディングをウインドウモールディングとして使用する例を示し、(a)は図8のU−U断面図、(b)はS−S断面図、図2(a)は図8のC−C断面図、図3は第2部材の脚部の高さHおよび庇状部の突出量Pの変化を示す線図である。
【0032】
車体パネル1は窓開口部11の周辺部において、側部フランジ1eおよび底部フランジ1fにより凹部12が形成されている。底部フランジ1fからの車体パネル1の高さ、すなわち側部フランジ1eの高さはアッパー部Uにおける高さをhu、コーナー部Cにおける高さをhc、サイド部Sにおける高さをhsとすると、hu<hc<hsとなっていて、hsの高さのピラーパネル1cがコーナー部付近で徐々に高さが低くなってセンタールーフパネル1aに連続している。
【0033】
窓(フロントウインドウ)2は車体パネル1の窓開口部11を覆うように窓板3が組付けられ、車体パネル1と窓板3の間隙13に沿ってウインドウモールディング4が組付けられている。14は窓板の裏面外周部に形成された不透明プリント層、15はダムラバー、16は接着剤である。窓板3はダムラバー15によって全周において底部フランジ1fからほぼ一定の高さdに配置されている。
【0034】
ウインドウモールディング4はサイド部Sにおいて窓板3と車体パネル1間の間隙13に沿って取付けられ、コーナー部C付近からアッパー部Uにおける窓板3と車体パネル1の間隙13に沿って取付けられるように連続して一体的に形成されており、窓板3側に取付けられる樹脂製の第1部材21と、車体パネル1側に取付けられる樹脂製の第2部材22とから構成されている。
【0035】
第1部材21は窓板3の車外側に位置する頭部21aから実質的に同じ高さの脚部21bが間隙13に挿入されるように伸びる構造を有し、金属ワイヤ、ガラス繊維糸等の耐伸縮性に富み変形可能な芯材23が埋込まれて一体化している。頭部21aの車外側には別の樹脂からなるカバー部21cが形成され、脚部21bの先端部から窓板3側に折返し状に弾発係止片21dが形成され、これらが窓板3の端部への取付手段となっている。第1部材21はサイド部Sからコーナー部Cを経てアッパー部Uに至るほぼ全長にわたって実質的に同一の横断面形状を有する。
【0036】
第2部材22は車体パネル1の車外側に位置する頭部22aから車体パネル1の高さの変化に対応して変化し、高さの異なる脚部22bが間隙13に挿入されるように伸びて、サイド部Sでせき24を形成しており、車体パネル1側には下部に弾性リップ25が形成されてウインドウモールディング4を窓板3側に押しつけ、上部に感圧式両面粘着テープ等の固着材26が取付けられている。第2部材22は頭部22aが少なくともサイド部Sでは窓板3側に突出量Psだけ伸びて庇状部27が形成されており、コーナー部C付近で脚部22bの高さが低くなって、アッパー部Uでは第1部材21の頭部21aと重なるように構成されている。
【0037】
このような第2部材22はサイド部Sからコーナー部Cを経てアッパー部Uに至る長手方向の全域にわたってほぼ同じ横断面形状に構成された頭部22aから、高さの異なる脚部22bが伸びた構造になっており、これにより第2部材22の高さHは、アッパー部Uにおける高さをHu、コーナー部Cにおける高さをHc、サイド部Sにおける高さをHsとした場合、Hu<Hc<Hsの関係を持ち、図3のように変化している。
【0038】
また庇状部27の突出量Pは、アッパー部Uにおける突出量をPu、コーナー部Cにおける突出量をPc、サイド部Sにおける突出量をPsとすると、図1(a)、(b)および図2(a)ではPu=Pc=Psとなっていて、全体が同一突出量になっているが、図2(a)に27aの点線で示すようにコーナー部Cおよび/またはアッパー部Uにおいて、庇状部27を除去して突出量をゼロにしてもよい。この場合図3に示すように、Pu≦Pc<Psのようになる。なお突出量の変化は徐々にかつ滑らかにするのが、風切音、安全、美観のうえから好まましい。
【0039】
上記の第1および第2部材21、22は好ましくは脚部21b、22bの先端の一体化部28で一体化しており、その付近に折り曲げを容易にする為のくびれ部29が形成されている。第1および第2部材21、22はそれぞれ同種または異種の樹脂により一体化部28以外は離れた状態で押出成形され、実質的に同じ高さの第1部材21の脚部21bと高さの異なる第2部材22の脚部22bとが下側で連結するように一体成形された押出成形材からなる。これらの樹脂は互いに相溶性を有する樹脂を使用し一体化部28で溶着して連結するのが好ましい。このような樹脂の例としては第1部材をHsA60〜95°程度の硬度の軟質もしくは半硬質ポリ塩化ビニル樹脂、第2部材も軟質で耐クリープ性に富む塩素化エチレンコポリマー樹脂として組合せて使用できる。
【0040】
上記のウインドウモールディング4は第1および第2部材21、22を脚部21b、22bの先端部における一体化部28を支点として折り曲げて、サイド部からコーナー部を経てアッパー部またはドリップ溝部に至る長手方向のほぼ全長にわたって重ねた状態で溶着一体化して接合部76が形成されており、この状態で脚部21b、22bを窓板3と車体パネル1の間隙13に挿入して取付け、使用される。この場合窓板3の周辺部裏面に接着剤16を塗布して車体パネル1の凹部12にはめ込み、窓板3の外周部に第1部材21のカバー部21cおよび弾発係止片21dを、側部フランジ1eに第2部材22の弾性リップ25を係合させてウインドウモールディング4を仮固定した状態で、第2部材22の背面に取付けられた固着材(例えば両面粘着テープ)26を側部フランジ1e側に押圧して固着し、接着剤16を硬化させて組付けることができる。
なお、第1部材21の横断面形状を略J字状にして、窓板3を表裏両面から挟さんで固定するときには、窓板3の外周縁に予めウインドウモールディング4を固定しておき、その後に接着剤16を塗布して車体パネルの窓開口部11に窓板3を取り付けることもできる。
【0041】
使用状態においては、サイド部Sにおいて第2部材22によりせき24が形成されているため、窓板3上を流れる雨水(水滴)10はワイパーによって掻寄せられて図1(b)の矢印に示すようにせき24に集められ、せき24に沿って流れるため、第2部材22又はピラーパネル1cを横切って越えるサイドウインドウへの横流れが防止される。第2部材22は車体パネル1の高さの変化に応じて、コーナー部C付近で変化し、アッパー部Uでは実質的にフラッシュ面20を形成し、図1(a)の矢印に示すように、車両走行中の空気抵抗を小さくするとともに雨水の横流れを許容する。
【0042】
上記のウインドウモールディング4は第1部材21と第2部材22から構成されるため、それぞれの部材に別の機能を持たせることができ、別部材の複合機能および複合美が得られる。すなわち第1部材21は窓板3への取付および装飾部材として、実質的に同一の形状および意匠に仕上げることができる。そして第2部材22はサイド部Sにおけるせき形成と、全域にわたる車体パネル1への取付および装飾部材として、第1部材21とは独立した長手方向に変化する形状および意匠に仕上げることができる。
【0043】
ウインドウモールディング4は第1および第2部材21、22がいずれも、サイド部からコーナー部を経てアッパー部またはドリップ溝部に至る長手方向のほぼ全長にわたって連続して設けられ、脚部21b、22bにおける一体化部分で折曲げて重ねた状態で使用されるため、従来のもののように切除作業や切除のばらつきによる不適合、ならびに不連続による外観不良などが防止され、優れた外観が得られる。
【0044】
第1部材21はサイド部Sからコーナー部Cを経てアッパー部Uに至るほぼ全長にわたって実質的に同一の横断面形状を有するものが使用されているが、部分的に異なる横断面形状を有していてもよく、例えばコーナー部C付近では曲げやすいように部分的に薄肉部分を形成して横断面形状を変化させていてもよい。また図2(a)に示すように第1部材21の表面とは異色を呈する装飾条片21eを外表面部に被着してもよい。
【0045】
第2部材22は頭部22aが少なくともサイド部Sで窓板3側に庇状部27を有し、コーナー部C付近で脚部22bの高さが低くなって、アッパー部Uでは第1部材21の頭部21aと重なるように構成することにより、サイド部で雨水のせき止め効果が高くなり、優れた機能性、装飾性、作業性が得られる。
【0046】
第2部材22の庇状部27の突出長さが長いと車両走行中の風切音が大きくなり、また手等が触れて車体パネルから離れる方向に力が作用したときに窓板側に倒れやすくなるが、せき24の高さを高くすると庇状部27の突出長さが短くても雨水10のせき止め効果が得られるので、風切音を小さくしかつ倒れにくくすることができる。この場合でも第1部材21が取付安定性と装飾性を負担するため、第2部材22の庇状部27を任意の突出長さとすることができる。
【0047】
第2部材22の頭部22aはサイド部Sからコーナー部Cを経てアッパー部Uに至る長手方向のほぼ全長にわたって実質的に同一の横断面形状に形成しているが、場合によってはサイド部Sにおいて形成された庇状部27を図2(a)の破線27aで示すようにコーナー部C付近でなくなるように除去し、あるいはアッパー部Uでも除去することができ、これにより車両の走行中にせきに沿って流れる空気流が遮られることがないので風切音が小さくなる。
【0048】
第1部材21および第2部材22は押出成形により一体成形されたものであるが、第1部材21は予め所定断面形状に形成された長尺材例えば金属ストリップやこれを折曲げて所定の異形横断面形状に形成したもの、あるいはアルミニウム合金や樹脂の押出材等を用い、これを押出成形型に供給して押出成形により第2部材22と一体化したものでもよい。
【0049】
上記のウインドウモールディング4は、サイド部Sからコーナー部Cを経てアッパー部Uに至る長手方向のほぼ全域にわたって、窓板3側に取付けられる第1部材21と、車体パネル1側に取付けられる高さの異なる第2部材22とが、それぞれ車外側の頭部21a、22aから伸びる脚部21b、22bの先端部で一体化しているので、製造および取付が容易で、第2部材22がサイド部Sにおいてせき24を形成するとともに、コーナー部C付近で変化してアッパー部Uでは第1部材21と実質的なフラッシュ面20を形成することができ、かつ全長にわたって連続した優れた外観を有するモールディングが得られる。
【0050】
第1部材21がサイド部Sからコーナー部Cを経てアッパー部Uに至る長手方向のほぼ全長にわたって実質的に同一の横断面形状を有するものは、全体に均一な取付安定性と装飾性が得られる。そして第2部材22の頭部22aがサイド部Sで窓板3側に庇状部27を有し、コーナー部C付近で脚部の高さが低くなって、アッパー部Uでは第1部材21の頭部21aと重なっているものは、サイド部Sにおける雨水のせき止め効果およびアッパー部Uにおけるフラッシュ面形成効果が大きくなる。また第2部材22の頭部22aがサイド部Sからコーナー部Cを経てアッパー部Uに至る長手方向のほぼ全長にわたって実質的に同一の横断面形状を有するものは、均一な外観を与えるが、庇状部27が少なくともコーナー部C付近で除去されてなくなっているものは車両走行中の風切音が小さくなる。
【0051】
図2(b)はドリップモールディングに適用した場合を示す図8のD−D断面図である。ドリップモールディング6は前記ウインドウモールディング4とほぼ同様な形状の第1部材21および第2部材22から構成されている。すなわちサイド部Sでは図1(b)とほぼ同様に構成され、コーナー部Cでは図2(a)とほぼ同様に変化し、そのまま図2(b)に示すようにドリップ溝5に沿って伸びている。
【0052】
ドリップ溝5はセンタールーフパネル1aの側部フランジ1g、底部フランジ1hおよび立上壁1iによって形成されている。そして立上壁1iとサイドルーフパネル1bの側部フランジ1eとの間隙13aにドリップモールディング6の第1および第2部材21、22の脚部21b、22bが挿入され、第1部材21の頭部21aと弾発係止片21dが支持部1jおよび係止部1kに係合し、固着されている。この場合も、両面粘着テープ等の固着材を併用してもよい。なお16は両方の底部フランジをシールするシール材である。
【0053】
上記のドリップモールディング6は前記ウインドウモールディング4の場合とほぼ同様に取付けられ、ほぼ同様に使用される。この場合、窓2のアッパー部Uには別のアッパー用モールディングが使用される。センタールーフパネル1a上の水はドリップ溝5に集められるが、ドリップ溝5はせき24と接続しているため、両者に集められた水はこれらを通して流れる。他の構成および効果はウインドウモールディング4の場合と同様である。
【0054】
図4は前記ウインドウモールディング4(またはドリップモールディング6)の製造方法を示す系統図、図5は図4のA−A矢視図、図6(a)は図5のE−E断面図、(b)は第1可動型における樹脂流を示す模式図、図7(a)は整形装置を示す図4のB−B矢視図、(b)は他の実施形態を示す図4のA−A矢視図である。
【0055】
図4において、30は制御装置、31は芯材23用のアンコイラ、32は同ピンチローラ、33は芯材の移動量検出装置、34は押出成形型で固定型35、第1可動型36および整形装置37を有する。38は冷却装置(加硫を必要とするゴムの場合は加硫装置)、39は引取機、40は切断機である。
【0056】
モールディング4、6の製造方法は、まず図4に示すように、アンコイラ31からピンチローラ32を介して表面に接着剤層を形成した芯材23を送り出し、ロータリエンコーダ等の検出装置33により送出量を検出しながら押出成形型34の第1部材送出路41に供給して第1部材21の押出成形を行い、第2部材押出路42で押出成形される第2部材22と一体化させ、モールディング4、6を形成する。
【0057】
第1部材21および第2部材22の押出成形は、第1樹脂供給路43から軟質ないし半硬質の塩化ビニル樹脂やTPE樹脂のような第1樹脂44を供給し、第1樹脂流路45を通して第1部材送出路41に導入して第1部材21の頭部21a、脚部21bおよび弾発係止片21dを形成し、カバー部21cと一体化して第1オリフィス41aから押出す。
【0058】
一方第2樹脂供給路46から第1の樹脂よりも軟質で耐クリープ性に富む塩素化エチレンコポリマー樹脂や他のTPE樹脂のような第2樹脂47を供給し、その一部を第2樹脂流路48aから第1部材送出路41に導入してカバー部21cを形成して頭部21aと一体化するとともに、他の一部を第2樹脂流路48bから第2部材押出路42に導入して第2部材22を形成し、第2オリフィス42aから押出す。
【0059】
このとき検出装置33の検出信号49に基づく制御装置30からの駆動信号51により第1可動型36を移動させて、図3に示すように第2部材22の高さHをサイド部S、コーナー部C、アッパー部UにおいてHs>Hc>Huのように変化させる。サイド部SではHs2のように変化させてもよい。この場合、第2部材22の脚部22bの高さはサイド部Sの長手方向のほぼ全長にわたって変化することになる。
【0060】
第2部材22の脚部22bの高さを変化させる場合、第1可動型36は図5に示すように、ガイドフレーム52に沿って、ACサーボモータ、流体圧シリンダ等の駆動装置53によりロッド54を介して、矢印X方向に往復動することにより、第1可動型36のオリフィス36aがX方向に移動し、固定型35の第2部材押出路42の第2オリフィス42aから押出される第2樹脂47の一部を変形させて頭部22aを形成し、脚部22bの長さを変化させる。
【0061】
第1可動型36には図6(a)に示すように、カッタ55および樹脂排出口56が設けられており、カッタ55により樹脂流の一部を分離して第2部材とならない樹脂を排出樹脂57として樹脂排出口56から排出する。第1可動型36のX方向の移動によりカッタ55が55aの位置まで移動することにより、脚部22bの長さが短くなる。カッタ55で分離され第2部材となる樹脂は第1可動型36の変形流路58により変形されて頭部22aを形成する。この状態は図6(b)に模式的に図示されている。ここでa、b、c、dで囲まれる面積は頭部22aの面積と等しい。
【0062】
上記の操作は第2オリフィス42aから押出される樹脂の時間当りの押出量を一定にした時のものであるが、第1可動型36に樹脂排出口56を設けない場合には第2オリフィス42aの開口面積の増減に応じて制御装置30からの駆動信号59により押出機のモータ61の回転量を制御し、プーリ62、ベルト63、プーリ64を介して押出機のバレル65のスクリュウ66の回転量を制御し第2樹脂供給路46へ供給する第2樹脂47量の供給量を増減することができる。
【0063】
上記により第2部材押出路42で高さが変化するように形成された第2部材22は、第1部材送出路41から押出される第1部材21と脚部21b、22bの先端が一体化した状態で、第1、第2オリフィス41a、42aから押出された後、整形装置37で第1、第2部材21、22が一体化部28で折曲げられて一体化する。整形装置37は図7(a)に示すように、変形路71を有するシュー72と、溝73を有するローラ74とからなり、支軸75を軸として回転するローラ74で第2部材22を支持しながら、変形路71に第1部材21を通して変形させ、接合部76で溶着して一体化する。
【0064】
こうして得られるモールディング材50は冷却装置38で冷却されて固化し、引取機39で引取られて、走行式の切断機40で切断されてモールディング4、6が製造される。切断機40は制御装置30の駆動信号77によりモータ78が駆動されて切断機79が走行し、駆動信号81によりカッタ82が駆動してモールディング材50を切断する。
【0065】
切断位置は図3のXに示すように、ウインドウモールディングの場合にはサイド部Sの下端部、ドリップモールディングの場合にはサイド部Sの下端部及びルーフ部1aの後端とされるのが一般的であるが、他の場所でもよい。切断機40の駆動信号77、81は検出装置33の検出信号49から得られるが、別にモールディング材50の形状検出装置33aを切断機40の直前に設けて、その検出信号51aに基づいて切断機40を制御してもよい。
【0066】
図7(b)は第2部材の頭部の横断面形状を変形させる場合の例を示す図4のA−A矢視図である。この実施形態では、第1可動型36のオリフィス36aを横切るように第2可動型83が設けられていて、庇状部27に対応する位置にカッタ55aおよび樹脂排出口56aが設けられている。そして駆動装置(図示省略)によりロッド54aを介して矢印Y方向にガイドフレーム52aに沿って移動することにより、第2部材22の頭部22aの庇状部27をコーナー部Cにおいて、あるいはさらにアッパー部Uにおいても除去する。庇状部27の除去位置は図3に示されている。カッタ55aにより切除された庇状部27は樹脂排出口56aから排出される。この場合にもカッタ55aを使用する方法に代えて、前述したような第2樹脂47の供給量を制御する方法を採用することもできる。
【0067】
上記により製造されたモールディング4、6は前述のようにして使用される。上記の実施形態では、製品のモールディング4、6は図7(a)に示すように第1および第2部材21、22が整形装置37により折曲げられて、接合部76で接合一体化したものであるが、整形装置37による整形を省略し、図5の4、6に示すように、第1および第2部材21、22が一体化部28から放射状に開いた形状のモールディング4、6を製品とし、これを一体化部28で折曲げて重ねた状態で使用するようにしてもよい。
【0068】
また上記実施形態では第1および第2部材21、22を同時に押出成形により一体成形するようにしたが、時期をずらせて押出成形してもよく、例えば第1部材/又は第2部材を成形した後第2部材/又は第1部材を成形してもよい。また第1部材としては金属異形材のように、予め所定横断面形状に成形された長尺材からなる第1部材21を供給して送り出し、その途中において押出成形により第2部材22を成形して一体化させることもできる。この場合には脚部21bの一体成形に代えてPOM(ポリアセタール)樹脂、PA(ポリアミド)樹脂等の弾性樹脂から別途に作られたクリップ等を長尺材の長手方向に沿って間隙をへだてて複数個嵌合配置させてこれを第1部材の脚部とすることができる。さらに、この実施形態の場合、第1、第2部材21、22の一体化位置は、第1部材の頭部の位置に第2部材の脚部の下端部側と一体化するのが好ましい。
【0069】
さらに第2部材押出路42のオリフィス42aを横切るように第1可動型36を移動させて第2部材22の脚部22bの長さを変えながら頭部22aを形成し、第1部材21と一体化することにより、第2部材22の頭部22aが同形状で脚部22bの高さが変化するモールディングを効率よく製造することができる。また第1可動型36のオリフィス36aを横切るように第2可動型83を移動させることにより、第2部材22の頭部22aの横断面形状が変化するモールディングを効率よく製造することができる。

The first member extends from the side part to the upper part or the drip groove part through the corner part Longitudinal Generally, those having substantially the same cross-sectional shape over substantially the entire length are used. However, they may have partially different cross-sectional shapes. May be formed to change the cross-sectional shape.
[0017]
The second member has an eave-like portion on the side of the window plate at least in the side portion, and the height of the leg portion is reduced near the corner portion, and overlaps with the head portion of the first member in the upper portion or the drip groove portion. With such a configuration, the effect of damming rainwater at the side portions is enhanced, and excellent functionality, decorativeness, and workability are obtained.
[0018]
If the protruding length of the eaves-like portion of the second member is long, wind noise during vehicle running becomes large, and when a force acts in a direction away from the vehicle body panel by touching with a hand or the like, it easily falls down to the window plate side. However, if the height of the crest is increased, the effect of damming rainwater can be obtained even if the length of the eaves-shaped portion is short, so that the wind noise can be reduced and it is difficult to fall down. Even in this case, since the first member bears the attachment property and the decoration property, the eaves-like portion of the second member can have an arbitrary protruding length to have a function and a decoration property different from those of the first member.
[0019]
The head of the second member reaches the upper portion or the drip groove portion from the side portion through the corner portion Longitudinal Although it may be formed to have substantially the same cross-sectional shape over substantially the entire length, in some cases, the eaves-shaped portion formed at the side portion can be eliminated at least near the corner portion by removing or the like. The airflow flowing along the cough during traveling passes through the above-mentioned removal section without being interrupted, so that the wind noise is reduced.

In the above molding, the first member is sent out along the longitudinal direction through the first member delivery path formed in the extrusion mold, and the resin is supplied to the second member extrusion path communicating with the first member delivery path of the extrusion mold. Then, the second member is formed and integrated with the first member while changing the cross-sectional shape of the extrusion path by the first movable die, so that the manufacturing can be efficiently performed.
[0022]
In this case, a molding may be manufactured by integrally forming the second member by extrusion molding through a first member previously formed into a long material through the first member delivery path to manufacture a molding. The resin may be supplied to one orifice to extrude the first member, and the molding may be manufactured integrally with the second member extruded through the second member extrusion path (second orifice).
[0023]
The molding with the head of the second member having a constant cross-sectional shape moves the first movable die so as to cross the second orifice of the second member extrusion path, extrudes the resin from the orifice of the first movable die, and presses the first movable die. The head can be formed by changing the lengths of the legs of the two members, and can be manufactured by being integrated with the first member. In the molding in which the cross section of the head of the second member changes, the cross section of the head of the second member is changed by moving the second movable die across the orifice of the first movable die. Can be manufactured.

A cover portion 21c made of another resin is formed on the vehicle outside of the head portion 21a, and a resilient locking piece 21d is formed in a folded shape from the tip of the leg portion 21b toward the window plate 3 side. It is a means for attaching to the end. The first member 21 has substantially the same cross-sectional shape over substantially the entire length from the side portion S to the upper portion U via the corner portion C.
[0036]
The second member 22 changes from a head 22a located outside the vehicle body panel 1 in response to a change in the height of the vehicle body panel 1 and extends so that legs 22b having different heights are inserted into the gap 13. The side portion S forms a weir 24.

[0039]
The first and second members 21 and 22 are preferably integrated at an integrated portion 28 at the tip of the legs 21b and 22b, and a constricted portion 29 is formed in the vicinity of the integrated portion 28 to facilitate bending. . The first and second members 21 and 22 are extruded from the same or different resins in a state apart from each other except for the integrated portion 28. The legs 21b of the first member 21 having substantially the same height and the legs 22b of the second member 22 having different heights are integrally formed so as to be connected on the lower side. It consists of an extruded material. It is preferable that these resins be made of mutually compatible resins and welded and connected at the integrated portion 28. As an example of such a resin, the first member can be used in combination with a soft or semi-hard polyvinyl chloride resin having a hardness of about 60 to 95 ° HsA, and the second member can also be used in combination with a chlorinated ethylene copolymer resin having a soft and rich creep resistance. .
[0040]
The above-mentioned window molding 4 bends the first and second members 21 and 22 around the integrated portion 28 at the tip of the leg 21b or 22b as a fulcrum.

In the use state, since the weir 24 is formed by the second member 22 in the side portion S, the rainwater (water droplet) 10 flowing on the window plate 3 is raked by the wiper and is indicated by an arrow in FIG. As described above, the water is collected by the weir 24 and flows along the weir 24, so that the lateral flow to the side window beyond the second member 22 or the pillar panel 1c is prevented. The second member 22 changes in the vicinity of the corner portion C according to the change in the height of the body panel 1, and substantially forms the flash surface 20 in the upper portion U, as shown by the arrow in FIG. In addition, it reduces the air resistance during running of the vehicle and allows the rainwater to flow laterally.
[0042]
Since the above-mentioned window molding 4 is composed of the first member 21 and the second member 22, each member can be provided with another function, and a combined function and beauty of another member can be obtained. That is, the first member 21 can be finished to substantially the same shape and design as the attachment to the window plate 3 and the decorative member. Then, the second member 22 can be formed into a shape and a design that change in the longitudinal direction independent of the first member 21 as a crest formation in the side portion S, a mounting to the vehicle body panel 1 over the entire area, and a decoration member.

If the protruding length of the eave-like portion 27 of the second member 22 is long, wind noise during vehicle running becomes large, and when the force is applied in the direction away from the vehicle body panel by touching the hand or the like, it falls down to the window plate side. If the height of the weir 24 is increased, the effect of damming the rainwater 10 can be obtained even if the length of the eaves 27 is short, so that the wind noise can be reduced and the fall can be suppressed. Even in this case, since the first member 21 bears the mounting stability and decorativeness, the eaves-like portion 27 of the second member 22 can have an arbitrary protruding length.
[0047]

It can also be removed so that it disappears, or it can be removed at the upper part U, so that the airflow flowing along the crest during running of the vehicle is not obstructed, so that the wind noise is reduced.
[0048]
Although the first member 21 and the second member 22 are integrally formed by extrusion molding, the first member 21 is a long material, for example, a metal strip formed in a predetermined cross-sectional shape in advance, or a predetermined irregular shape formed by bending the metal strip. It may be formed into a cross-sectional shape, or may be formed by using an extruded material of an aluminum alloy or a resin, supplying the extruded material to an extrusion mold, and extruding and integrating the second member 22.
[0049]
The above-described window molding 4 extends from the side portion S to the upper portion U via the corner portion C. Longitudinal A first member 21 attached to the window plate 3 and a second member 22 having a different height attached to the vehicle body panel 1 have legs 21b extending from heads 21a, 22a on the vehicle outside, respectively, over substantially the entire area. Since it is integrated at the tip of the second member 22b, manufacture and mounting are easy, and the second member 22 forms the weir 24 at the side portion S, and changes near the corner C to form the first member 21 at the upper portion U. And the flash surface 20 can be substantially formed, and a molding having an excellent appearance continuous over the entire length can be obtained.
[0050]
The first member 21 reaches the upper portion U from the side portion S via the corner portion C. Longitudinal Those having substantially the same cross-sectional shape over substantially the entire length can provide uniform mounting stability and decorativeness as a whole. The head 22a of the second member 22 has an eave-like portion 27 on the side of the window plate 3 at the side portion S, and the height of the legs decreases near the corner portion C. The upper part U has a greater effect of damming rainwater in the side portion S and a flush surface forming effect in the upper portion U. The head 22a of the second member 22 reaches the upper portion U from the side portion S via the corner portion C. Longitudinal Those having substantially the same cross-sectional shape over substantially the entire length give a uniform appearance, but those in which the eaves-like portion 27 has been removed at least near the corner portion C have reduced wind noise during vehicle running.

Also in this case, a fixing material such as a double-sided adhesive tape may be used together. Reference numeral 16 denotes a sealing material for sealing both bottom flanges.
[0053]
The above-mentioned drip molding 6 is attached and used almost in the same manner as in the case of the window molding 4. In this case, another upper molding is used for the upper portion U of the window 2. The water on the center roof panel 1a is collected in the drip groove 5, but since the drip groove 5 is connected to the weir 24, the water collected by the two flows through them. Other configurations and effects are the same as those of the window molding 4.
