Description

【０００１】
【発明の属する技術分野】
本発明は、自動車のセンターピラートリム等の内装材に開口部を有するエンボス部を形成し、エンボス部を車体パネルに取着することによって内装材を車体パネルに装着した後、開口部の開口端部に形成した凹状の座面にキャップを嵌合装着して構成する自動車用内装材の開口部目隠し構造に関する。
【０００２】
【従来の技術】
従来この種の自動車用内装材の開口部目隠し構造としては、例えば図６に示すものが知られている。
【０００３】
図６によれば、内装材ａの車体パネルｂへの装着は、内装材ａに開口部ｃを有するエンボス部ｄを形成し、エンボス部ｄをスクリューｅを用いて車体パネルｂに取着することによって行っていた。
【０００４】
そして、エンボス部ｄの開口部ｃを目隠しするために、内装材ａにおける開口部ｃの開口端部に拡径した凹状の座面ｆを形成し、座面ｆにキャップｇを嵌合装着していた。
【０００５】
キャップｇは、その下面ｉに複数個の係止爪ｈが形成されていて、係止爪ｈを、開口部ｃを挿通させた後、内装材ａの裏面に係合させることによって、係止爪ｈとキャップｇとの間で内装材ａを狭着して固定されている。
【０００６】
【発明が解決しようとする課題】
上記のように構成する従来構造においては、キャップｇは、内装材ａを車体パネルｂに装着するためのエンボス部ｄの開口部ｃを目隠しして、内装材ａの美観を損ねないために使用されるものである。
【０００７】
このために、キャップｇの取付け作業上或いはキャップｇ及び座面ｆの製作上のばらつきを考え、キャップｇの外周側壁ｋと座面ｆの立壁ｍとの間に通常０．５ｍｍ位の隙間ｔを設定している。
【０００８】
しかしながら、内装材ａとキャップｇとは、それぞれ別々に製作された樹脂等の成形品であることから、互いに製作誤差による製品寸法にばらつきが生じ、キャップｇを座面ｆに嵌合装着した場合、キャップｇが座面ｆの所定位置に装着されず、隙間ｔがキャップｇの全周に亘って均一化しないことがある。
【０００９】
このために、内装材ａ或いはキャップｇを成形するための成形型に微妙なチューニングを加える必要があり、成形型のコスト高の要因となっている。
【００１０】
そこで、従来、キャップｇの外周側壁ｋに互いに離間して間欠的に配置された当てリブ(不図示)を形成して、当てリブを座面ｆの立壁ｍと底面ｎとの交叉隅部ｐに当接させるように構成し、当てリブの成形形状をチューニングすることにより、キャップの全周に亘って隙間ｔの均一化を図って、成形型全体のコストダウンを図っていた。
【００１１】
しかしながら、キャップｇの外周側壁ｋに形成した当てリブは、外周側壁ｋと座面ｆの立壁ｍとの間の隙間ｔの存在により、隙間ｔを通して内装材ａの外観から見えてしまい、見栄えを損ねていた。
【００１２】
そこで、本発明は、かかる点に鑑み、キャップと座面との隙間の均一化を図るための当てリブを従来同様キャップの外周側壁に形成するも、当てリブを内装材の外観から見え難くして、内装材の美観向上を図った自動車用内装材の開口部目隠し構造を提供することを目的としている。
【００１３】
【課題を解決するための手段】
上記目的を達成するために本発明は、センターピラートリム等の内装材に開口部を有するエンボス部を形成し、該エンボス部を車体パネルに取着することによって前記内装材を前記車体パネルに装着した後、前記開口部の開口端部に形成した凹状の座面にキャップを嵌合装着して構成する自動車用内装材の開口部目隠し構造であって、前記座面の立壁を外方に向かって拡開する傾斜面に形成するとともに、前記立壁に対向するように、前記キャップの外周側壁を外方に向かって拡開する傾斜面に形成し、且つ、前記キャップにおける前記外周側壁に間欠的に配置された複数個の当てリブを形成し、該当てリブを前記座面の底部と前記立壁との交叉隅部に当接した状態で前記キャップを前記座面に嵌合装着したことを特徴とするものである。
【００１４】
本発明によれば、座面の立壁を外方に向かって拡開する傾斜面壁に形成するとともに、立壁に対向するように、キャップの外周側壁を外方に向かって拡開する傾斜面にすることによって、座面とキャップとの隙間における座面の底面側を暗きょ的に形成して、キャップの外周側壁に当てリブを設けたとしても、当てリブを内装材の外観から見えにくくしている。
【００１５】
また本発明によれば、キャップにおける外周側壁に間欠的に配置された複数個の当てリブを形成し、当てリブを座面の底部と立壁との交叉隅部に当接した状態でキャップを座面に嵌合装着して構成しており、当てリブの存在による内装材の外観見栄えを劣化させずに、当てリブの成形形状を調整することによって、キャップと内装材側の座面との隙間をチューニングして、キャップの全周に亘って、隙間の均一化を図ると共に、成形型のコストダウンを実現できる。
【００１６】
また本発明は、センターピラートリム等の内装材に開口部を有するエンボス部を形成し、該エンボス部を車体パネルに取着することによって前記内装材を前記車体パネルに装着した後、前記開口部の開口端部に形成した凹状の座面にキャップを嵌合装着して構成する自動車用内装材の開口部目隠し構造であって、前記座面の立壁を外方に向かって拡開する傾斜面に形成するとともに、前記立壁に対向するように、前記キャップの外周側壁を外方に向かって拡開する傾斜面に形成し、且つ、前記キャップにおける前記外周側壁から下面まで延在するように間欠的に配置された複数個の当てリブを形成し、該当てリブを前記座面の底部と前記立壁との交叉隅部に当接した状態で前記キャップを前記座面に嵌合装着しており、当てリブの成形形状を調整することによって、キャップと内装材側の座面との隙間をチューニングして、キャップの全周に亘って、隙間の均一化を図ると共に、キャップの下面に存する当てリブ形状をチューニングすることによってキャップ上面を確実に内装材と面一に連続させることができ、結果的に成形型のコストダウンを実現している。
【００１７】
【発明の実施の形態】
以下、本発明における第１の実施の形態について、図１乃至図３を用いて説明する。
【００１８】
図１は、内装材の開口部目隠し構造を描画した斜視図、図２は本発明に係る第１の実施の形態による分解斜視図、図３は同じく図１のＡ−Ａ断面図である。
【００１９】
図１乃至３において、センターピラートリム等の内装材１の車体パネル２への装着は、内装材１に開口部３を有するエンボス部４を形成し、エンボス部４をスクリュー５を用いて車体パネル２に取着することによって行う。
【００２０】
また、エンボス部４の開口部３は、その開口端部に拡径した凹状の座面６にキャップ７を嵌合装着することによって、目隠しされている。
【００２１】
そして、座面６の立壁６ａが、開口部３の外方に向かって拡開する傾斜面に形成されており、立壁６ａに対応して、略平行に対向するように、キャップ７の外周側壁７ａが、やはり外方に向かって拡開する傾斜面に形成されている。
【００２２】
キャップ７における外周側壁７ａには、間欠的に配置された複数個の当てリブ８が形成されており、当てリブ８は、キャップ７を座面６に嵌合装着した状態で、座面６の立壁６ａと底部６ｂとの交叉隅部６ｃに当接している。
【００２３】
さらに、キャップ７の下面７ｂには、互いに対向する一対の係止爪９が形成されていて、係止爪９を開口部３を挿通させた後、エンボス部４の側壁に形成した係合孔１０から内装材１の裏面に係合させることによって、係止爪９キャップ７との間で内装材１を狭着し、キャップ７を固定している。
【００２４】
上記のように構成する場合、成形型における当てリブ８の形成部位を適宜チューニングすることによって、座面６とキャップ７との隙間ｔを均一化することができ、成形型全体コストダウンが期待できる。
【００２５】
また、座面６の立壁６ａを外方に向かって拡開する傾斜面壁に形成するとともに、立壁６ａに対向するように、キャップ７の外周側壁７ａを外方に向かって拡開する傾斜面にすることによって、座面６とキャップ７との隙間ｔにおける座面６の底面６ｂ側を暗きょ的に形成して、当てリブ８を内装材１の外観から見えにくくして、美観向上を図っている。

図４及び図５によれば、当てリブ８がキャップの外周側壁７ａと共に下面７ｂにまで延在形成されている点、上記第１の実施の形態と異なり、その他の構成は上記第１の実施の形態と同様としている。
【００２８】
したがって、キャップ７の下面７ｂに存する当てリブ８の形状をチューニングすることによって、キャップ７の上面７ｃを確実に内装材１と面一に連続させることができ、内装材１の美観向上にさらに貢献することができる。
【００２９】
【発明の効果】
以上説明したように、本発明によれば、座面の立壁を外方に向かって拡開する傾斜面壁に形成するとともに、立壁に対向するように、キャップの外周側壁を外方に向かって拡開する傾斜面にすることによって、座面とキャップとの隙間における座面の底面側を暗きょ的に形成して、キャップの外周側壁に当てリブを設けたとしても、当てリブを内装材の外観から見えにくくして、内装材の美観向上を図っている。
