Description

【0001】
【発明の属する技術分野】
本発明は大きさや形状を自由に設定でき、他部品の配置を妨げない灯火器の通気孔構造に関する。
【0002】
【従来の技術】
車両等に用いられる灯火器は、バルブの点灯時に灯火器内の温度が高くなり、この点灯時と消灯時との灯火器内の温度差のために灯火器内面に水滴がつくことがある。これを防止するため、灯火器には、通常灯火器内と外部とを連通させる通気孔が設けられる。
この灯火器の通気孔としては、例えば、実用新案登録第2547379号「スクータ車両の灯火器取付構造」に記載されたものが知られている。
【0003】
上記技術は、同公報の第17図に示される通り、リフレクタとなるケース40と、このケース40の前部に取付けたレンズ51と、これらのケース40及びレンズ51のそれぞれの下部をラビリンス状の嵌合部とし、この嵌合部に内外の通気を行うために設けた通気孔(符号なし)とを備えるものである。
【0004】
【発明が解決しようとする課題】
上記技術では、ラビリンス状の嵌合部に通気孔を設けるため、通気孔の形状や大きさに制約を受ける。
また、通気孔の下方には、同公報の第5図及び第8図に記載されているように、前カバー11が配置されているが、通気孔の通気性を損なわないように、この前カバー11を上記したラビリンス状の嵌合部の下部から所定のクリアランスを開けて配置しなければならず、前カバー11が大型になり、前カバー11の形状に制約を受ける。
そこで、本発明の目的は、大きさや形状の設定自由度が大きく、他部品の配置に制約を与えない灯火器の通気孔構造を提供することにある。
【0005】
【課題を解決するための手段】
上記目的を達成するために請求項1は、前方を開口し椀形状に形成したリフレクタと、このリフレクタの椀形状の底に電球を取付けるために円筒状に形成したソケット部と、リフレクタの開口部を塞ぐように配置したレンズとからなる灯火器において、リフレクタから、ソケット部の上面をカバーする庇を延ばし、この庇を、ソケット部と所定の間隔を隔てた円弧状に形成し、灯火器が最も傾いた場合でも、庇には、ソケット部の軸線を通る鉛直線に対して切欠きの反対側に鉛直線から庇の端部までの余裕円弧長さを有し、ソケット部の上部に、ソケット部の軸線方向に延びるように円筒状のソケット部を後端から途中まで切欠いて所定の幅を有する矩形状の切欠きを開け、電球の口金部分に、鍔と、この鍔の前方に配置されたOリングとを設け、この鍔で切欠きの後端部の開口部を後方から覆うとともに、切欠きの中間部をOリングが横切るようにOリングで電球の口金部分とソケット部との間を塞ぎ、庇を鍔よりも後方に突出させるとともに、鍔の外径をソケット部の外径と等しいか又はソケット部の外径より大きくして、鍔で切欠きの後端開口部全体を後方から覆うようにし、切欠きにてリフレクタ内の密閉空間と外部とを連通させることで空気の出入りを可能にし、庇及び鍔にて切欠きへ侵入する水を阻止するようにした。
【0006】
リフレクタから庇を延ばし、ソケット部に切欠きを開けて、通気孔の形状や大きさの設定自由度を高める。
また、空間に余裕のあるリフレクタの背面側に庇及び切欠きを設けるため、他部品の配置に制約を与えない。
更に、電球の口金部分に鍔を設け、この鍔で切欠きの開口部を後方から覆ったことで、灯火器後方から飛散してきた水しぶき等を通気孔に入らないように鍔で阻止する。
【0007】
請求項2は、庇が、ソケット部の軸線を通る鉛直線に対して両側にそれぞれ角度45°開いている。
【0008】
請求項3は、ソケット部が、このソケット部に電球を固定するために内周面に突出させた凸部を備える。
【0009】

バルブ組立体53は、光源となるバルブ本体75と、このバルブ本体75を支える口金部分としてのバルブ基部76と、このバルブ基部76の後部に設けた前述の鍔64及びコネクタ受け部65と、バルブ組立体53を回転させてソケット部52の後述する凸部79…に結合させるためにバルブ基部76の外周面に設けたL字形凸部77とからなる。なお、78はOリング、CLはソケット部52の軸線、即ちバルブ組立体53の基準線である。
【0015】
リフレクタ51の円弧状壁62は、ソケット部52の後端よりも長さPだけ後方に突出する。更に、望ましくは、ソケット部52にバルブ組立体53を取付けた時に、円弧状壁62は、バルブ組立体53の鍔64よりも所定の長さQ、例えばQ=2mmだけ後方に突出する。
また、ソケット部52の後端の外径をD、バルブ組立体53の鍔64の外径をD1とすると、D1≧Dである。
上記の切欠き73と、この切欠き73の開口部を塞ぐバルブ組立体53の鍔64とで、本発明の通気孔80を形成する。
【0016】
図4(a),(b)は本発明に係る通気孔を形成する切欠きの説明図であり、(a)はヘッドランプ17の背面図、(b)はソケット部52の平面図を示す。
(a)において、ソケット部52の切欠き73は、円筒の最上部に、即ちソケット部52の軸を通る鉛直面を含む位置に形成したものであり、水平方向に所定の幅W、例えばW=5mmの幅を有するものである。
【0017】
円弧状壁62は、ソケット部52と同心状に形成し、ソケット部52の軸線CL(図3参照。図4(a)では表裏方向に延びる。)を通る鉛直線VLに対して両側にそれぞれ角度θ、例えばθ=45°開き、ソケット部52の外周面と所定の間隔C、例えばC=5mmの距離を隔てたものである。
ソケット部52は、ソケット部52にバルブ組立体53(図3参照)を固定するために内周面に突出させた凸部79…を備える。
【0018】
(b)において、切欠き73はソケット部52の軸線CLの延びる方向に矩形状に形成したものである。
【0019】
以上に述べた通気孔80の作用を次に説明する。
図5(a)〜(c)は本発明に係る通気孔の作用を説明する第1作用図である。
(a)において、ヘッドランプ17の上方から水滴dが落下してきた場合、水滴dは、円弧状壁62に沿って流れ落ち、通気孔80に入り込むことはない。
(b)において、バルブ本体75を点灯した場合、ヘッドランプ17内のエアはバルブ本体75が発する熱で暖められて膨張し、矢印で示すように、通気孔80を通ってヘッドランプ17外へ流出する。
【0020】
(c)において、(b)の後に、バルブ本体75を消灯した場合には、ヘッドランプ17内のエアの温度が低下して収縮するため、矢印で示すように、外部からヘッドランプ17内へエアが通気孔80を通って流入する。
このように、通気孔80は、通気機能を維持しつつ防滴機能を果たすことができる。
【0021】
図6(a),(b)は通気孔の比較例を示す作用図である。
(a)は、ヘッドランプ100のソケット部101の下部に通気孔102を開けた状態を示す。ここで、103はソケット部101の外周面、104はバルブ本体である。
【0022】
例えば、上方から水滴dが落下してきた場合、水滴dは、ソケット部101の外周面103に沿って流れ、ソケット部101の下部に達する。
この時、水滴dは通気孔102を膜状になって塞ぐ可能性がある。この状態で、例えば、点灯しているバルブ本体104を(b)のように消すと、ソケット部101内に流入するエアとともに水滴dが入り込む可能性がある。
【0023】
図7(a),(b)は本発明に係る通気孔の作用を説明する第2作用図であり、スクータ型車両が傾いた状態を示す。
(a)において、ヘッドランプ17の上方から水滴dが落下してきた場合、水滴dは、円弧状壁62に沿って流れ落ちる。
車体が最も傾いてヘッドランプ17が角度α傾いた場合でも、円弧状壁62には図に示すように余裕長さL(Lは円弧長さである。)があるため、水滴dは通気孔80に入り込むことはない。
【0024】
(b)において、バルブ本体75を点灯した場合、ヘッドランプ17内のエアは膨張し、矢印で示すように通気孔80を通ってヘッドランプ17外へ流出する。また、バルブ本体75を消灯した場合、ヘッドランプ17内のエアが収縮するため、矢印とは反対に外部からヘッドランプ17内へエアが通気孔80を通って流入する。
このように、ヘッドランプ17が傾いた状態でも、通気孔80は、通気機能を維持しつつ防滴機能を果たすことができる。
【0025】
図8は本発明に係る通気孔の作用を説明する第3作用図であり、図3に示したように、バルブ組立体53の鍔64の外径D1が切欠き73を設けたソケット部52の外径Dと等しいか又は大きいことと、円弧状壁62がソケット部52に取付けたバルブ組立体53の鍔64より後方へ長さQだけ突出することとから、図8に示すように、例えば、ヘッドランプ17の後方又は斜後方から水滴dが飛んできた場合でも、水滴dは、鍔64及び円弧状壁62に阻まれて通気孔80に侵入することがない。
従って、上記の円弧状壁62及び鍔64によって、通気機能を維持しつつ防滴効果をより向上させることができる。
【0026】
尚、本発明の通気孔80を形成する切欠き73の形状は、図4(b)に示した矩形の他に、丸形、多角形、ソケット部52の軸線CLの延びる方向が長手方向になるように形成した長孔、楕円でもよい。
また、図4(a)に示した円弧状壁62の形状は、円弧状に限るものではなく、平面状、自由曲面、あるいは幾つかの面を組合わせたものでもよい。
【0027】
【発明の効果】
本発明は上記構成により次の効果を発揮する。
請求項1の灯火器の通気孔構造は、リフレクタから庇を延ばし、ソケット部の上部に切欠きを開けたので、ソケット部に切欠きを開けるだけで通気孔とするため、切欠きの形状や大きさの設定自由度を増すことができる。
また、リフレクタ背面の余裕のある空間に庇及び切欠きを設けるため、他部品の配置に制約を与えることはない。
更に、電球の口金部分に鍔を設け、この鍔で切欠きの開口部を後方から覆ったので、灯火器後方から飛散してきた水しぶき等が通気孔に入る心配はない。
【0028】
請求項2の灯火器の通気孔構造は、庇が、ソケット部の軸線を通る鉛直線に対して両側にそれぞれ角度45°開いている
【図面の簡単な説明】
【0029】
請求項3の灯火器の通気孔構造は、ソケット部が、このソケット部に電球を固定するために内周面に突出させた凸部を備える。
