【発明の属する技術分野】
本発明は、モールの取り付け構造に関し、特に車のボディ側面にプロテクタとして設けられる樹脂部材に取り付けるモール取り付け構造に関するものである。
【０００２】
【従来の技術】
図１０に示すように、従来から車のボディ側面１００には、水平に設けられたプロテクタとなる長尺の樹脂部材１０１に装飾用モール１０２を取り付けている。
このような従来の長尺の樹脂部材１０１、及び装飾用モール１０２の車のボディ側への取り付けは、
（１）図１１に示すように、長尺の樹脂部材１０１を、予め車のボディ側面側に両面テープ１０３で固定し、更に長手方向に間隔を置いて複数の図示せぬクリップで固定し、次いで、湾曲した装飾用モール１０２の幅方向両端の挿入片１０４を樹脂部材１０１の挿入溝１０５に挿入し、両面テープ１０６または接着剤によって樹脂部材１０１に取り付ける。
（２）図１２に示すように、湾曲した装飾用モール１０２の幅方向両端の挿入片１０４を樹脂部材１０１の挿通孔１０７に挿通し、モール１０２を両面テープ１０６または接着剤で樹脂部材１０１に取り付けた後、挿入片１０４の先端部１０４ａを折り返して樹脂部材１０１に係止して取り付け、最後に樹脂部材１０１を車のボディ側に両面テープ１０３などで取り付けている。
（３）上記（１）、（２）を併用するなどの方法があった。
【０００３】
【発明が解決しようとする課題】
しかしながら、（１）では両面テープ１０６または接着剤をモール１０２に施す必要がある。（２）では（１）の理由に加えて、取り付け工程において、幅方向両端の挿入片１０４の先端部１０４ａを折り返す工程が必要である。そのため、モール１０２の取り付けに必要とする部品点数、作業工程が多くなるという課題があった。従って、当然上記（１）、（２）を併用する（３）も同様の課題を有していた。
【０００４】
そこで、本発明は、取り付けが簡単で取り付け工程の削減が可能、そしてコストダウンを図ることができるモールの取り付け構造を提供することを目的とする。
【０００５】
【課題を解決するための手段】
前記の課題を解決するための手段として、本発明に係る請求項１のモール取り付け構造は、長尺の樹脂部材の表面に装飾用のモールを取り付けるためのモール取り付け構造であって、前記樹脂部材の長手方向には前記モールの幅方向両端部を嵌め込むための係止溝が設けられ、この係止溝の内部には表面側に延出される係止片が幅方向に複数平行に設けられ、これらの係止片の先端部には、前記樹脂部材の幅方向外側に向けて突出する係止突部が形成され、前記モールの幅方向両端部には、幅方向内側に向けて突出する折り曲げ部が形成され、前記モールの幅方向両端部を前記係止溝に嵌め込み、前記折り曲げ部が前記係止突部に係合されることによって、前記モールが前記樹脂部材に取り付けられることを特徴とする。
【０００６】
このような構成としたことにより、請求項１に記載の発明に係るモール取り付け構造では、樹脂部材にモールを外側から嵌め込むことができるので、両面テープや接着剤などを削減し、取り付け工程の削減が可能となるから、コストダウンを図ることができる。
【０００７】
本発明に係る請求項２のモール取り付け構造は、前記係止片が、前記樹脂部材本体と一体形成されることを特徴とする。
【０００８】
このような構成としたことにより、請求項２に記載の発明に係るモール取り付け構造では、係止片を樹脂部材本体と一体形成される形状に設定することによって、樹脂部材全体の製造コストを削減することができる。
【０００９】
本発明に係る請求項３のモール取り付け構造は、前記折り曲げ部が、外側に凹となるように湾曲して形成されることを特徴とする。
【００１０】
このような構成としたことにより、請求項３に記載の発明に係るモール取り付け構造では、折り曲げ部を湾曲して形成することによって、樹脂部材の係止溝に嵌まり易くなるとともに、変形し易い形状となるので、係止溝への差し込みが容易になる。
【００１１】
本発明に係る請求項４のモール取り付け構造は、前記折り曲げ部に、幅方向に沿って内側に延びる直線部が形成されることを特徴とする。
【００１２】
このような構成としたことにより、請求項４に記載の発明に係るモール取り付け構造では、折り曲げ部の先端を直線状に形成することによって、樹脂部材の係止突部に当接させる部分を寸法管理が容易な面状の部分とすることができる。これによって、モールの外形線と樹脂部材の外形線との隙間寸法をより正確に設定することが可能となり、所望の見栄えの良い意匠を確実に得ることができる。
【００１３】
【発明の実施の形態】
以下、図面を参照して本発明に係るモール取り付け構造の実施の形態を説明する。参照する図面において、図１はボディ側面にプロテクタとなる樹脂部材及びモールを備えた車の側面図、図２は樹脂部材及びモールの全体図、図３は図２のＡ−Ａ線矢視図である。
車１のボディ側面には、前輪３のフロントフェンダ２の後部からドア４を経てリアフェンダ５の後部まで、プロテクタとなる長尺の樹脂部材６を水平に取り付け、この樹脂部材６の上半部に装飾用のモール７を取り付けている。樹脂部材６及びモール７は、フロントフェンダ２、ドア４，４、及びリアフェンダ５毎に設けられている。これにより車１のボディ側面の装飾性を向上させると同時に、ドア４を開けた際等に他の車と軽く接触しても車１のボディ側面を保護できるようにしている。
樹脂部材６は、例えば、塩化ビニル樹脂などのプラスチックで射出成形したものであり、モール７は、例えば、ステンレス板を板金加工したものである。尚、樹脂部材６の射出成形については後で詳述する。
【００１４】
図２（ａ）、図３に示すように、モール７の前端部（図３の左端）は樹脂部材６の開口部８に差し込んで係止する。この開口部８の後部側（図３の右手方向）の樹脂部材６の下面には、鍵状の係合部９が形成され、この係合部９にクリップ１０を係合させて、樹脂部材６をボディ側１１に固定している。樹脂部材６のクリップ１０によるボディ側１１への取り付けについては後で詳述する。
【００１５】
次に図２のＢの拡大図である図４と、図４のＣ−Ｃ線矢視図である図５と、図４のＤ−Ｄ線矢視図である図６を参照してモール７の樹脂部材６への取り付けについて説明する。
図５に示すように、樹脂部材６の長手方向であって、図４のＣ−Ｃ線の部分には、モール７の幅方向両端部７ａを嵌め込むための係止溝１２，１３が設けられている。係止溝１２は、底のある穴であるが、係止溝１３は底の突き抜けた孔である。係止溝１２，１３の内部には表面側に延出される係止片１４，１５が幅
方向に複数個並行に設けられている。そして係止片１５の先端部には、樹脂部材６の幅方向外側に向けて突出する係止突部１５ａが形成されている。
そして樹脂部材６は、その下部に形成された２本の脚部６ａ，６ｂを両面テープ２５でボディ側１１に固定されている。
【００１６】
係止溝１２，１３に嵌め込まれるモール７の幅方向両端部７ａの内、図の上側の幅方向端部７ａには、幅方向内側に向けて突出し、更に外側に凹となるように湾曲した折り曲げ部７ｂが形成されている。そして、モール７の図の下側の幅方向端部７ａには、幅方向内側に向けて突出し、幅方向に沿って内側に延びる直線部７ｃが形成されている。
底のある係止溝１２には、モール７の上側の折り曲げ部７ｂが挿入される。折り曲げ部７ｂは湾曲しているため係止溝１２に嵌め易く、また、変形し易い形状であるので、係止溝１２への差し込みが容易である。
底の突き抜けた係止溝１３には、嵌め込まれた直線部７ｃが更に係止突部１５ａに係合される。直線部７ｃは、寸法管理が容易な面状となって係止突部１５ａに当接されるので、モール７の外形線と樹脂部材６の外形線との隙間寸法ｓをより正確に設定することが可能となり、隙間寸法ｓが長手方向の意匠線となって所望の見栄えの良い意匠を確実に得ることができる。
尚、係止片１４と１５の間に孔１６が形成されるが、この孔１６の大きさによって係止片１４と１５の変形し易さを適宜設定することができる。
【００１７】
同様にして、図６に示すように、樹脂部材６の長手方向であって、図４のＤ−Ｄ線の部分には、モール７の幅方向両端部７ａの上部端部を嵌め込むために、係止溝１２の奥に鍵状に屈曲して係止溝１７が形成され、底の突き抜けた孔になっている。モール７の幅方向両端部７ａの下部端部を嵌め込むための係止溝１８は、底のある穴である。
係止溝１７，１８の内部には表面側に延出される係止片１９，２０が幅方向
に複数並行に設けられている。そして係止片１９の先端部には、樹脂部材６の幅方向外側に向けて突出する係止突部１９ａが形成されている。
底のある係止溝１８には、モール７の下側の端部７ａが挿入され、係止される。また、係止溝１２に挿入されたモール７の上部の端部７ａは、底の突き抜けた係
止溝１７の入口で、嵌め込まれた折り曲げ部７ｂが更に係止突部１９ａに係合される。
【００１８】
係止溝１７と同様の係止溝１７が図４のＣ−Ｃ線に関し対称な位置に形成されている。また、係止溝１３も図４のＣ−Ｃ線に関し対称に形成されている。これにより係止溝１３と１７，１７とはＣ−Ｃ線に関し左右対称になる。これら３つの係止溝１３と１７，１７を一組として樹脂部材６の長手方向の中間部のもう１箇所にも同様の係止溝１３と１７，１７の組が形成されており、モール７を樹脂部材６に安定して取り付けることができる。また、樹脂部材６にモール７を外側から嵌め込むことができるので、両面テープや接着剤などを削減し、取り付け工程の削減が可能となるから、コストダウンを図ることができる。
【００１９】
樹脂部材６はクリップで車１のボディ側１１に長手方向の数箇所で固定されているが、これについて図７を参照して説明する。
図７に示すように、ボディ側１１の樹脂部材６に断面視で入口が狭く奥が広い凸形の係合溝２３が設けられ、クリップホルダ２４が樹脂部材６と一体に形成されている。尚、図７の右側にはボディ側１１から視た場合のクリップホルダ２４を描いてある。この係合溝２３にクリップ１０の係合片１０ａを挿入することで係合させ、クリップ１０の１対の拡開部１０ｂをボディ側１１に形成された図示せぬ穴に差し込み、クリップ１０の拡開部１０ｂがボディ側１１の穴から抜けないようにし、樹脂部材６をボディ側１１に固定する。樹脂部材６の長手方向の数箇所にこのような係合溝２３が形成され、クリップ１０を係合させて樹脂部材６の長手方向の全長がボディ側１１に固定されている。
尚、サイドプロテクタモールについては次で説明する。
【００２０】
モール７の後端部のボディ側１１への固定の仕方について図８を参照して説明する。
モール７の後端部（図の右端）は樹脂部材６の開口部３０に差し込んで係止する。この開口部３０の前方（図の左手方向）の樹脂部材６の下面には、モール７の下面に鍵状に屈曲したサイドプロテクタモール２７が固定されており、サイドプロテクタモール２７の下半部はボディ側１１に埋め込まれる。また、サイドプロテクタモール２７の樹脂部材６側の下面には係合溝２８が形成され、この係合溝２８にクリップ１０の係合片１０ａが図の左手方向から係合される。そして、クリップ１０の１対の拡開部１０ｂをボディ側１１に形成された図示せぬ穴に差し込み、樹脂部材６をボディ側１１に固定する。
【００２１】
次に樹脂部材６の射出成形について図９を参照して説明する。
図９（ａ）は樹脂部材６の鋳型の上型３１と下型３２の断面を示し、上型３１と下型３２の間に形成される空洞３３が樹脂部材６の断面形状となる。
図９（ｂ）で上型３１と下型３２を合わせ、図示せぬ鋳湯口から上型３１と下型３２の間の空洞３３に、例えば、塩化ビニル樹脂のような溶融した熱可塑性樹脂を注入する。
次いで、図９（ｃ）で熱可塑性樹脂が冷えて固まったら、上型３１と下型３２を外し樹脂部材６を取り出す。これにより係止片１５，１９と長尺の樹脂部材６とが一体成形される。
以上のように、モール７の前端部と後端部は樹脂部材６の開口部８，３０に差し込むことで係止し、モール７の中間部はモール７の幅方向の両端部７ａ，７ａを係止溝１２，１３，１７，１８に嵌め込み、樹脂部材６の係止突部１５ａ，１９ａに係合させることによって、モール７を樹脂部材６に取り付けることができるので、両面テープや接着剤などを削減し、取り付け工程の削減が可能となるから、コストダウンを図ることができる。
以上、本発明について、好適な実施形態の一例を説明した。しかし、本発明は、前記実施の形態に限られず、本発明の趣旨を逸脱しない範囲で、適宜設計変更が可能である。
