Description

【０００１】
【発明の属する技術分野】
本発明は、乗用車のドア等に取付けられる車両用サイドミラーの技術分野に属するものである。
【０００２】
【従来技術】
今日、椀形状をしたボディにミラー板を角度調節自在に取り付けたサイドミラーをドアに取付けることが多用されており、このようなサイドミラーにおいて、そのボディ部分にサイドターンランプを組み込んで車両の折曲方向を点灯表示するようにしたものが知られている。そしてこのようなサイドミラーは、図５に示すように、透光性のある導光レンズ２０をボディ２１の外周に組み込み、該導光レンズ２０の一端に発光ダイオード（ＬＥＤ）や電球等の光源２２を組み込んで構成し、運転席に配した方向指示レバーの操作に連繋して光源２２を点灯（点滅点灯）し、これによって導光レンズ２０を発光させて折曲方向を表示するようにしている。
【０００３】
ところが前記従来のものは、光源２２を、導光レンズ２０の平坦状となった導光面２０ａに対向させた配置となっており、このため、光源２２から発せられる照射光の一部が導光面２０ａに入らず漏れてしまうことになって照射効率が悪いという問題がある。このようなものにおいて照射効率は、光源を導光面に近接させるほど高くなり、その最善の形態としては当接させることである。ところが光源を導光面に当接させたり、近接しすぎた場合に、導光レンズをボディに組み込む際、例えばインサート成形時や超音波振動による溶着時、光源と導光面とが干渉して光源が押圧状態で振動する等して光源に悪影響を与えるという問題があり、ここに本発明が解決せんとする課題がある。
【０００４】
【課題を解決するための手段】
本発明は、上記の如き実情に鑑みこれらの課題を解決することを目的として創作されたものであって、請求項１の発明は、車両に取付けられるサイドミラーであって、該サイドミラーのボデイに、光源と、該光源からの光を入光してボデイ外に照射するための導光レンズとを備えて構成されるランプ手段を設けるにあたり、前記光源は第一、第二の光源を備え、導光レンズは横長形状であり、第一の光源は、導光レンズの横長形状一端部に形成された入光部に向けて照射するものであり、第二の光源は、導光レンズの横長形状中途部に位置していてボデイ内からボデイ外に向けて照射するように構成すると共に、入光部は筒状であり、第一の光源は該筒状の入光部に遊嵌状に内嵌していることを特徴とする車両用サイドミラーである。
そしてこのようにすることにより、光源から発せられる光を効率良く導光レンズに入光することができると共に、光源が入光部に内嵌しながら、車体振動等で光源の不用意な振動を防止するようにしたものである。
請求項２の発明は、入光部筒奥は、第一の光源側に膨出した球面形状になっていることを特徴とする請求項１記載の車両用サイドミラーである。
【０００５】
【発明の実施の形態】
次ぎに、図面の記載に基づいて本発明の実施の形態について説明する。図面において、１は電動格納式のドアミラー（サイドミラー）であって、該ドアミラー１は、椀形状をしたボディ２に、角度調節用モータ（図示せず）を内装したユニットケース３を組み込み、該ユニットケース３に角度調節自在に組み込んだミラー板４を組込んで構成されるが、これらの構成に付いては何れも従来通りであるので、その詳細については省略する。
【０００６】
５はアクリル樹脂、ポリカルボネート樹脂等からなる透光性素材で形成された横長状をした導光レンズであって、該導光レンズ５の一端部には、発光ダイオードからなる光源６が対向配設される入光部が構成されているが、該入光部は、空隙を存して形成される外筒部５ａと内筒部５ｂの二重筒形状になっており、その筒奥部に球面形状となった入光面５ｃが形成されている。一方、７はＡＢＳ樹脂、ポリプロピレン樹脂等からなる不透光素材を用いて形成されるハウジングであって、該ハウジング７は導光レンズ５のボディ２から露出する面を除いて被覆内装するものであって、ハウジング７には、前記入光部と対向するようにして有底筒状の光源収容室７ａが形成されている。そして光源収容室７ａの開口端縁が前記外筒部５ａと端面当接するようにして組み付けられる。
【０００７】
前記光源６は、基板６ａに灯部６ｂが植設されて構成されるが、基板６ａが前記光源収容室７ａに一体的に組込まれることで取付けられる。そして前述した導光レンズ５をハウジング７に組込んだ状態で灯部６ｂの先端部（実質的に光を発する部分）が内筒部５ｂに遊嵌状に内嵌していて非接触状態となっている。因みに、光源６の点灯制御は、車両の運転席に配した方向指示レバーの操作に連繋して実行されるものであることはいうまでもない。
尚、本実施の形態では、導光レンズ５の中途部に第二の光源８を備えて構成されている。
【０００８】
叙述の如く構成された本発明の実施の形態において、ドアミラー１に導光レンズ５および光源６を設けて、ドアミラー１に方向指示機能を備えたものでありながら、光源６は、導光レンズ５の入光部に形成される筒部である内筒部５ｂに内嵌組込みされている。この結果、光源６から発せられる光は、内筒部５ｂの奥底面だけでなく、筒内周面からも入光することになって効率良い入光が果せ、輝度の向上ができることになる。
【０００９】
しかも光源６の内筒部５ｂへの嵌入は、光が発せられる灯部６ｂであるため、内筒部５ｂの内周面を可及的に灯部６ｂに近接できることになって、入光率のさらなる向上が果せる。そのうえこの場合に、灯部６ｂは内筒部５ｂには接しない遊嵌状の嵌入であるため、機体振動等があった場合に、灯部６ｂが内筒部５ｂと干渉してしまうことを回避し、光源６の損傷防止に寄与することになる。
【００１０】
なお、本発明は前記実施の形態に限定されるものではなく、例えば導光レンズの機能としては、方向指示機能でなく、夜間の足元照明機能であってもよい。
