Description

【０００１】
【発明の属する技術分野】
この発明は、ランプカバーとハウジングとから成り、ランプカバーをシーソ動作させることにより点灯及び消灯を行う室内照明灯に関するものである。
【０００２】
【従来の技術】
自動車用の室内照明灯において、発光するレンズ部位とその点灯制御するスイッチとが離れて設けられるものが多い。近年、意匠性を高めるため、レンズ自体をスイッチ動作することで点灯制御を行う室内照明灯が実用化されている。例えば、実公平１−３２５９１号では、レンズをシーソ動作させて点灯制御（オン、オフ、ドア連動点灯）させる室内照明灯が開示されている。
【０００３】
実公平１−３２５９１号では、レンズ側に一方の板金接片を取り付け、ハウジング側に他方の板金接片を取り付け、レンズのシーソ動作によって、該板金接片の接続を切り替えてバルブへの通電を接／断している。ここで、レンズのシーソ操作にクリック感（節度感）を持たせるため、ハウジングの側壁に突起を設け、レンズ側の対応位置に凹凸を設け、レンズをシーソ動作した際に、該凹凸がハウジング側の突起を乗り越えるようにしている。
【０００４】
一方、上述した発光するレンズ部位とその点灯制御するスイッチとが離れて設けられた室内照明灯において、特に操作フィーリング（クリック感（節度感））の良さを求めたものでは、スイッチに、回路切り替え接触部にコイルスプリングとボール状の接触子とを組み合わせた構造が用いられる。ボール状の接触子が回路切り換えの機能を果たすと共に、相手側接触子の突起を乗り越える際にクリック感を発生する構造である。この構造では、ボール状の接触子がコイルスプリングにより付勢されているため、突起の乗り越えがスムーズであり、軽快なクリック感（節度感）が得られる。この構成をレバータイプのスイッチに応用した例として実開平３−６０４３６号が、スライドタイプのスイッチに応用した例として特公平７−８２７８７号がある。
【０００５】
【発明が解決しようとする課題】
シーソ動作の実公平１−３２５９１号の室内照明灯では、上述したように、クリック感（節度感）をレンズ側の凹凸がハウジングの側壁に突起を乗り越えることで得ており、凹凸、突起の撓みによるものであるため、上記実開平３−６０４３６号、特公平７−８２７８７号のようにコイルスプリングとボール状の接触子とを組み合わせた構造に比べて節度感が乏しかった。また、製品精度によって、操作が堅いもの、軽すぎるものが出た。
また、シーソ動作の実公平１−３２５９１号は、組み付けが難しく、比較的小さな室内照明灯には適用が困難であった。
【０００６】
本発明は、上述した課題を解決するためになされたものであり、その目的とするところは、節度感のある操作を可能にするとともに、表面側からの組み付けが可能なレンズシーソ動作式の室内照明灯を提供することにある。
【０００７】
【課題を解決するための手段】
請求項１の発明は、上記目的を達成するため、ランプカバーとハウジングとから成り、ランプカバーをシーソ動作させることにより点灯及び消灯を行う室内照明灯において、
前記ハウジングが略矩形形状の収容部を有し、該収容部の短手側の側壁に固定接点を設け、長手側の対向する側壁に一対の凸部を形成し、
前記凸部により揺動可能に支持され、前記固定接点側へ弾性体により付勢される導電性球体からなる可動接点を保持する可動接点保持部材を備え、
前記ランプカバーが、前記凸部により揺動可能に支持され、前記可動接点保持部材を連動させるためのリンク部材を有することを技術的特徴とする。
【０００８】
請求項１の室内照明灯では、ランプカバーをシーソ動作させることにより、ランプカバーにリンク部材を介して連動する可動接点保持部材を揺動させ、該可動接点保持部材に配設された可動接点（導電性球体）により、固定接点の接続を切り替えて点灯及び消灯を行う。弾性体により付勢される導電性球体からなる可動接点を用いるため、ランプカバーのシーソ動作に節度感を与えることができる。
ここで、組み立ては、ハウジングの凸部に可動接点保持部材を取り付けた後、ランプカバーを該凸部に組み付ければよい。表面側から可動接点保持部材、ランプカバーを取り付けれるで、容易に組み立てることが可能である。
【０００９】

【００１０】
請求項２の室内照明灯では、ランプカバーをシーソ動作させることにより、ランプカバーにリンク部材を介して連動する可動接点保持部材を揺動させ、該可動接点保持部材に配設された可動接点（導電性球体）により、固定接点の接続を切り替えて点灯及び消灯を行う。弾性体により付勢される導電性球体からなる可動接点を用いるため、ランプカバーのシーソ動作に節度感を与えることができる。
ここで、組み立ては、ハウジングのボス部に通孔を嵌め入れることで可動接点保持部材を取り付けた後、切欠きを有する第１の通孔を該ハウジングのボス部に嵌入し、同時に、切欠きを有する第２の通孔を可動接点保持部材のボス部に嵌入することで、ランプカバーを取り付ける。表面側から可動接点保持部材、ランプカバーを取り付けれるで、容易に組み立てることが可能である。
【００１１】
請求項３の発明は、ランプカバーとハウジングとから成り、ランプカバーをシーソ動作させることにより点灯及び消灯を行う室内照明灯において、
前記ハウジングが略矩形形状の収容部を有し、該収容部の短手側の側壁に固定接点を設け、長手側の対向する側壁に一対のボス部を形成し、
前記ボス部に挿通される通孔と、該通孔を挟んで前記収容部の長手側の側壁に沿ってそれぞれ延在し前記ランプカバーと当接する当接部をそれぞれ設けた１対のアームとを有し、前記固定接点側へ弾性体により付勢される導電性球体からなる可動接点を一方のアームに保持させる可動接点保持部材を備え、
前記ランプカバーが、当該ランプカバーをシーソ動作させるための前記ハウジング側のボス部に嵌入可能な切欠きを有する通孔を有する通孔を有することを技術的特徴とする。
【００１２】
請求項３の室内照明灯では、ランプカバーをシーソ動作させることにより、ランプカバーに当接部を介して可動接点保持部材を揺動させ、該可動接点保持部材に配設された可動接点（導電性球体）により、固定接点の接続を切り替えて点灯及び消灯を行う。弾性体により付勢される導電性球体からなる可動接点を用いるため、ランプカバーのシーソ動作に節度感を与えることができる。
ここで、組み立ては、ハウジングのボス部に通孔を嵌め入れることで可動接点保持部材を取り付けた後、切欠きを有する通孔を該ハウジングのボス部に嵌入することでランプカバーを取り付ける。表面側から可動接点保持部材、ランプカバーを取り付けれるで、容易に組み立てることが可能である。
【００１３】
請求項４の室内照明灯では、ランプカバーの第１の通孔が、切欠からのボス部の抜け防止のための爪を有するため、例えば、カーテンエアバッグが展開したときのように大きな衝撃が加わっても、ランプカバーが脱落することがない。
【００１４】
請求項５の室内照明灯では、ランプカバーの通孔が、切欠からのボス部の抜け防止のための爪を有するため、例えば、カーテンエアバッグが展開したときのように大きな衝撃が加わっても、ランプカバーが脱落することがない。
【００１５】
【発明の実施の形態】
以下、本発明の実施形態に係る室内照明灯について図を参照して説明する。
[第１実施形態]
図１、図２は第１実施態様に係る室内照明灯１０と吹き出し用ダクト８０とを組み込んだ車両用部品９０を示し、図１（Ａ）は正面を、図１（Ｂ）は背面を示し、図２は、図１（Ａ）のＡ−Ａ断面を示している。
【００１６】
開口８８に設けられたダクト８０は、風向を調整する５枚のプレート８２と、プレート８２を保持するホルダー８４と、プレート８２を連動させるリンク８６とを備える。図２（Ａ）に示すように５枚のプレート８２を保持するホルダー８４は、支軸８４ａにより、車両用部品９０を構成するハウジング９２に対して回動可能に支持されている。
【００１７】
図１（Ａ）に示すように室内照明灯１０は、正面側にシーソ動作可能なランプカバー２０を備える。ランプカバー２０のＯＦＦ部２２ａを押圧することで、バルブ１２（図１（Ｂ）参照）をオフする。また、ＯＮ部２２ｂを１段押圧することで、ドアと連動してバルブ１２が点灯する。即ち、ドアを開けるとバルブ１２が点灯し、ドアを閉じるとバルブ１２が消灯する。更に、ＯＮ部２２ｂを１段押圧することで、ドアとは無関係にバルブ１２が常時点灯する。
【００１８】
図３に室内照明灯の組み立て状態を示す。室内照明灯１０は、ランプカバー２０と、鉄球からなる可動接点３０を保持する可動接点保持部材４０と、ハウジング９２に形成された略矩形形状の収容部５０と、固定接点６２を備える配線プレート６０とから成る。
【００１９】
ランプカバー２０の下面には、下方へ延在し、該ランプカバーを支持するための１対の支持板２４、２４と、可動接点保持部材４０を連動させるためのリンク板２６、２６とが設けられている。支持板２４、２４の先端には、切欠き２４ａを有する第１通孔２４ｂが形成されている。一方、リンク板２６、２６の先端には、切欠き２６ａを有する第２通孔２６ｂが形成されている。
【００２０】
コ字状に形成された可動接点保持部材４０には、コ字状の先端部に、一対の通孔４２、４２が穿設されている。コ字状の基部側の中央に、上記可動接点３０を保持するボス４６が形成され、基部近傍のコ字状の内面側に、上記ランプカバー２０のリンク板２６、２６の第２通孔２６ｂへ嵌入する１対のボス４４、４４が形成されている。可動接点３０を保持するボス４６の内側には、コイルスプリング３２及び可動接点３０を収容するための図示しない非貫通孔が設けられている。
【００２１】
収容部５０は、短手側の側壁５２Ａ、５２Ｂと、長手側の側壁５４Ａ、５４Ｂと、底板５６とを備える。底板５６には、中央に開口５６ａが、側壁５２Ａ側に開口５６ｂが設けられている。一方の側壁５２Ａ側には、固定接点６２を取り付けるための傾斜部５２ａが設けられている。他方の側壁５２Ｂ側には、コネクタを収容するためのコネクタ枠５２ｂが形成されている。また、長手側の対向する側壁５４Ａ、５４Ｂには、上記支持板２４、２４の第１通孔２４ｂに嵌入して、ランプカバー２０を揺動可能に支持する一対のボス５８、５８が設けられている。
【００２２】
配線プレート６０の固定接点６２は、ａ接点６２ａ、ｂ接点６２ｂ、ｃ接点６２ｃを備える。配線プレート６０は、ａ接点６２ａに接続されたａ配線６４ａと、ｂ接点６２ｂに接続されたｂ配線６４ｂと、ｃ接点６２ｃに接続されたｃ配線６４ｃとの３本の配線から成る。ｂ配線６４ｂの中央には、バルブ１２を保持する一対の保持片６９が設けられている。ａ配線６４ａ、ｂ配線６４ｂ、ｃ配線６４ｃの固定接点６２との反対側の端部には、図示しないコネクタにそれぞれ接続されるａ端子６８ａ、ｂ端子６８ｂ、ｃ端子６８ｃが設けられている。なお、配線プレート６０には複数の通孔６６が穿設されている。
【００２３】
ここで、該室内照明灯の組み立ては、図１（Ｂ）に示すように、収容部５０の底板５６裏面側に設けられたボス５６ｃに通孔６６を嵌入することで、該配線プレート６０を取り付ける。この際、配線プレート６０の固定接点６２は、底板５６の開口５６ｂ（図３参照）を挿通して、側壁５２Ａ側の傾斜部５２ａに位置する。図２（Ｂ）に示すように固定接点６２の断面Ｒ形状のａ接点６２ａ、ｂ接点６２ｂ、ｃ接点６２ｃが、傾斜部５２ａに形成された断部５２ｃにそれぞれ位置するため、可動接点３０の動作でａ接点６２ａ、ｂ接点６２ｂ、ｃ接点６２ｃの位置がずれることがない。
【００２４】
次に、バルブ１２を、ｂ配線６４ｂの中央の一対の保持片６９に取り付ける。
そして、ボス４６にコイルスプリング３２及び可動接点３０を保持させた状態で、可動接点保持部材４０の通孔４２、４２を収容部５０のボス５８、５８に嵌入させることで、可動接点保持部材４０を取り付ける。
【００２５】
最後に、ランプカバー２０の支持板２４、２４先端の切欠き２４ａを有する第１通孔２４ｂを収容部５０のボス５８に嵌入し、同時に、リンク板２６、２６先端の切欠き２６ａを有する第２通孔２６ｂを可動接点保持部材４０のボス４４に嵌入することで、ランプカバー２０を取り付ける。
【００２６】
第１実施形態では、ハウジング９２の表面側から可動接点保持部材４０、ランプカバー２０を取り付けれるで、容易に組み立てることが可能である。このため、室内照明灯１０を小型に形成しても、組み立てが困難になることがない。
【００２７】
室内照明灯１０の点灯動作について、図２（Ａ）、及び、図２（Ａ）中の固定接点６２を拡大して示す図２（Ｂ）を参照して更に詳細に説明する。
図１（Ａ）を参照して上述したように、ランプカバー２０が図２（Ａ）中の反時計方向側に位置している状態で、可動接点保持部材４０も反時計方向側（上側）に位置し、図２（Ｂ）中に１点鎖線で示すように可動接点３０が、固定接点６２のａ接点６２ａの上側にある。この状態では、可動接点３０により何れの接点も接続されておらず、バルブ１２は消灯状態にある。
【００２８】
図１（Ａ）を参照して上述したようにＯＮ部２２ｂを１段押圧することで、ドアと連動してバルブ１２が点灯するようになる。即ち、上記シーソ動作によりランプカバー２０が図２（Ａ）中の反時計方向側と時計方向側との中間に位置し、ランプカバー２０にリンク板２６を介して可動接点保持部材４０が連動して、図中の中間に位置する。ここでは、図２（Ｂ）中に実線で示すように可動接点３０が、固定接点６２のａ接点６２ａとｂ接点６２ｂとの中間にある。この状態では、可動接点３０によりａ接点６２ａとｂ接点６２ｂとが接続され、図示しないバッテリのプラス側にドアと連動するスイッチを介して接続されたａ配線６４ａと、バッテリのマイナス側に接続されたｂ配線６４ｂとを介して、バルブ１２はドアと連動してバルブ１２が点灯するようになる。
【００２９】
図１（Ａ）を参照して上述したようにＯＮ部２２ｂを更に１段押圧することで、バルブ１２が常時点灯するようになる。即ち、上記シーソ動作によりランプカバー２０が図２（Ａ）中の時計方向側に位置し、ランプカバー２０にリンク板２６を介して可動接点保持部材４０が連動して、図中の時計方向（下側）に位置する。ここでは、図２（Ｂ）中に破線で示すように可動接点３０が、固定接点６２のｂ接点６２ｂとｃ接点６２ｃとの中間にある。この状態では、可動接点３０によりｂ接点６２ｂとｃ接点６２ｃとが接続され、バッテリのマイナス側に接続されたｂ配線６４ｂと、バッテリのプラス側に接続されたｃ配線６４ｃとを介して、バルブ１２が常時点灯するようになる。
【００３０】
ここで、可動接点３０が、図２（Ｂ）中の一点鎖線で示す固定接点６２のａ接点６２ａの上側にあるバルブ１２のオフ状態から、実線で示す可動接点３０が、固定接点６２のａ接点６２ａとｂ接点６２ｂとの中間にある状態へ移行する際には、コイルスプリング３２により付勢された可動接点３０が断面が半円状に形成されたａ接点６２ａを越える際に、コイルスプリング３２の弾性によりクリック感（節度感）を生じる。このため、ランプカバー２０のシーソ動作に節度感を与えることができる。
【００３１】
なお、図２（Ｂ）中に１点鎖線で示す可動接点保持部材４０が反時計方向側（上側）に位置している状態で、可動接点保持部材４０の先端の上側が、収容部５０の側壁５２Ａに設けられたストッパ７２に当接している。即ち、図３に示すランプカバー２０を外す際には、ランプカバー２０のリンク板２６、２６先端に設けられた第２通孔２６ｂが、該ストッパ７２に押されている可動接点保持部材４０のボス４４から抜ける。このため、ランプカバー２０と共に可動接点保持部材４０が外れることなない。即ち、ランプカバー２０を外して容易にバルブ１２を交換することができる。
【００３２】
[第２実施形態]
引き続き、本発明の第２実施形態に係る室内照明灯について図４及び図５を参照して説明する。
図４は、第２実施形態の室内照明灯の組み立て図であり、図５は断面図である。この第２実施形態の室内照明灯１０は、ランプカバー２０及び可動接点保持部材４０の構成を除いて、図１〜図３を参照して上述した第１実施形態と同様であるため、第２実施形態のランプカバー２０及び可動接点保持部材４０の構成についてのみ詳細に説明する。
【００３３】
図４に示すように、室内照明灯１０は、ランプカバー２０と、鉄球からなる可動接点３０を保持する可動接点保持部材４０と、ハウジング９２に形成された略矩形形状の収容部５０と、固定接点６２を備える配線プレート６０とから成る。
【００３４】
ランプカバー２０の下面には、下方へ延在し該ランプカバーを支持するための１対の支持板２４、２４が設けられている。支持板２４、２４の先端には、切欠き２４ａを有する通孔２４ｂが形成されている。
【００３５】
ヘ字状に形成された可動接点保持部材４０には、収容部５０のボス５８に挿通される通孔４２と、該通孔４２を挟んで収容部５０の長手側の側壁５４Ａ、５４Ｂに沿ってそれぞれ延在する第１アーム４０Ａ、第２アーム４０Ｂとが設けられている。第２アーム４０Ｂの端部側には、ランプカバー２０の裏面に当接する当接部４８Ｂが設けられている。第１アーム４０Ａの端部近傍には、ランプカバー２０の裏面に当接する当接部４８Ａが設けられ、先端側の中央に、上記可動接点３０を保持するボス４６が形成されている。可動接点３０を保持するボス４６の内側には、コイルスプリング３２及び可動接点３０を収容するための図示しない非貫通孔が設けられている。
【００３６】
収容部５０は、短手側の側壁５２Ａ、５２Ｂと、長手側の側壁５４Ａ、５４Ｂと、底板５６とを備える。一方の側壁５２Ａ側には、固定接点６２を取り付けるための傾斜部５２ａが設けられている。また、長手側の対向する側壁５４Ａ、５４Ｂには、上記支持板２４、２４の第１通孔２４ｂに嵌入して、ランプカバー２０を揺動可能に支持する一対のボス５８、５８が設けられている。
【００３７】
ここで、第２実施形態の室内照明灯１０の可動接点保持部材４０及びランプカバー２０の組み立ては、図４に示すように、可動接点保持部材４０の通孔４２、４２を収容部５０のボス５８、５８に嵌入させることで、可動接点保持部材４０を取り付ける。そして、ランプカバー２０の支持板２４、２４先端の切欠き２４ａを有する第１通孔２４ｂを収容部５０のボス５８に嵌入することで、ランプカバー２０を取り付ける。
【００３８】
第２実施形態では、ハウジング９２の表面側から可動接点保持部材４０、ランプカバー２０を取り付けれるで、容易に組み立てることが可能である。このため、室内照明灯１０を小型に形成しても、組み立てが困難になることがない。
【００３９】
室内照明灯１０の点灯動作について、図５を参照して説明する。
ランプカバー２０が、図中に示すように反時計方向側と時計方向側との中間に位置している際に可動接点保持部材４０も図中の中間に位置する。可動接点３０は固定接点６２のａ接点６２ａとｂ接点６２ｂとの中間にある。この状態では、可動接点３０によりａ接点６２ａとｂ接点６２ｂとが接続され、図示しないバッテリのプラス側にドアと連動するスイッチを介して接続されたａ配線６４ａと、バッテリのマイナス側に接続されたｂ配線６４ｂとを介して、バルブ１２はドアと連動してバルブ１２が点灯するようになる。
【００４０】
ここで、図１（Ａ）を参照して上述したようにＯＦＦ部２２ａを押圧することで、ランプカバー２０が反時計方向にシーソ動し、ランプカバー２０裏面に当接する当接部４８Ｂを介して可動接点保持部材４０も反時計方向に揺動し、可動接点３０は固定接点６２のａ接点６２ａの上側に来る。この状態では、可動接点３０により何れの接点も接続されておらず、バルブ１２は消灯状態にある。
【００４１】
反対に、図１（Ａ）を参照して上述したようにＯＮ部２２ｂを押圧することで、ランプカバー２０が時計方向へシーソ動し、ランプカバー２０裏面に当接する当接部４８Ａを介して可動接点保持部材４０も時計方向へ揺動し、可動接点３０が、固定接点６２のｂ接点６２ｂとｃ接点６２ｃとの中間に来る。この状態では、可動接点３０によりｂ接点６２ｂとｃ接点６２ｃとが接続され、バッテリのマイナス側に接続されたｂ配線６４ｂと、バッテリのプラス側に接続されたｃ配線６４ｃとを介して、バルブ１２は常時点灯するようになる。
【００４２】
ここで、可動接点３０が、固定接点６２のａ接点６２ａの上側にあるバルブ１２のオフ状態から、固定接点６２のａ接点６２ａとｂ接点６２ｂとの中間にある状態へ移行する際には、コイルスプリング３２により付勢された可動接点３０が断面が半円状に形成されたａ接点６２ａを越える。このとき、コイルスプリング３２の弾性によりクリック感（節度感）を生じ、ランプカバー２０のシーソ動作に節度感を与えることができる。
【００４３】
[第２実施形態の改変例]
引き続き、本発明の第２実施形態の改変例に係る室内照明灯について図６を参照して説明する。
図６（Ａ）は、第２実施形態に係る室内照明灯１０に用いられるランプカバー２０の支持板２４に設けられた先端の切欠き２４ａを有する通孔２４ｂを示している。図６（Ｂ）は、第２実施形態の改変例に係る室内照明灯１０に用いられるランプカバー２０を示している。改変例では、支持板２４に設けられた通孔２４ｂの先端の切欠き２４ａに爪２４ｃが設けられている。爪２４ｃは、揺動板２４ｄにより図中奥側及び手前側に揺動可能に支持される。該爪２４ｃは、下端に内側を指向する傾斜が設けられ、上端は平坦に形成されている。
【００４４】
図４を参照して上述したように、ランプカバー２０を取り付ける際には、収容部５０のボス５８が、爪２４ｃの下端の傾斜と当たり、揺動板２４ｄにより爪２４ｃが図６中の奥側に待避し、ボス５８が通孔２４ｂに達すると、揺動板２４ｄの復元力により爪２４ｃが元の位置に戻り、爪２４ｃの上端の平坦部がボス４８の下端に当接する。
【００４５】
第２実施形態の改変例では、ランプカバー２０の通孔２４ｂが、切欠き２４ａからのボス５８の抜け防止のための爪２４ｃを有するため、例えば、カーテンエアバッグが展開したときのように大きな衝撃が加わっても、ランプカバー２０が脱落することがない。この改変例の構成は、第２実施形態の室内照明灯に適用したが、第１実施形態の室内照明灯にも適用できることは言うまでもない。

BACKGROUND OF THE INVENTION
The present invention relates to an interior illumination lamp that includes a lamp cover and a housing and is turned on and off by operating the lamp cover in a seesaw manner.
[0002]
[Prior art]
In many interior lighting lamps for automobiles, a lens portion that emits light and a switch for controlling the lighting thereof are provided apart from each other. In recent years, in order to improve the design, an indoor illumination lamp that performs lighting control by switching the lens itself has been put into practical use. For example, Japanese Utility Model Publication No. 1-332591 discloses an indoor illumination lamp that performs a seesaw operation on a lens to control lighting (ON, OFF, door-linked lighting).
[0003]
In Japanese Utility Model 1-332591, one sheet metal contact piece is attached to the lens side, the other sheet metal contact piece is attached to the housing side, and the connection of the sheet metal contact piece is switched by the seesaw operation of the lens to energize the valve. Connected / disconnected. Here, in order to give a click feeling (moderation feeling) to the seesaw operation of the lens, a protrusion is provided on the side wall of the housing, and an unevenness is provided at the corresponding position on the lens side. I try to get over the protrusion.
[0004]
On the other hand, in the interior illumination light in which the above-described lens portion that emits light and the switch for controlling the lighting thereof are provided apart from each other, in particular, when a good operation feeling (click feeling (moderation feeling)) is required, A structure in which a coil spring and a ball-shaped contact are combined in the switching contact portion is used. The ball-shaped contact serves as a circuit switching function and generates a click feeling when getting over the protrusion of the counterpart contact. In this structure, since the ball-shaped contact is urged by the coil spring, the protrusion can be smoothly moved over and a light click feeling (moderation feeling) can be obtained.
