Description

【０００１】
【産業上の利用分野】
本発明は、例えばバン型車両や海上コンテナの後部や側部に設けられた観音開扉の開閉用ハンドルを掛止する際に用いられるハンドル掛金装置の改良に関する。
【０００２】
【従来の技術】
従来、この種のハンドル掛金装置としては、例えば特開平３−４３５７６号、特開平３−４３５７７号、実開平３−３１６５９号に記載された圧縮バネ式のものが知られている。
これは、基本的には、基体と、基体に対して閉位置から開位置まで回動可能に設けられた掛金体と、基体と掛金体に設けられた支持ピンと、各支持ピンに揺動可能に設けられたバネ受体と、両バネ受体間に介設されて掛金体を閉位置又は開位置に保持する圧縮バネと、から構成されている。
而して、この様なものは、圧縮バネを用いているので、掛金体を確実且つ迅速に閉位置又は開位置に保持する事ができる。
ところが、この様なものは、部品点数が多いと共に、支持ピンに対してバネ受体が揺動可能に設けられていたので、組立が煩雑で、多くの手間と時間が掛かる難点があった。
【０００３】
【発明が解決しようとする課題】
本発明は、叙上の問題点に鑑み、これを解消する為に創案されたもので、その目的とする処は、組立が容易に行なえる様にしたハンドル掛金装置を提供するにある。
【０００４】
【課題を解決するための手段】
本発明のハンドル掛金装置は、基本的には、基体と、基体に対して閉位置から開位置まで回動可能に設けられた掛金体と、基体と掛金体に設けられたバネ受体と、両バネ受体間に介設されて掛金体を閉位置又は開位置に保持する圧縮バネと、両バネ受体に離脱不能に掛合されて圧縮バネを囲繞して保持するバネ筒体と、から構成した事に特徴が存する。
【０００５】
【作用】
掛金体が開位置に回動されると、掛金体が圧縮バネに依り開位置に保持され、ハンドルを掛金体と基体から離脱できる。
掛合体が開位置の時、ハンドルが基体に落込まれると、掛金体が閉位置に回動され、掛金体が圧縮バネに依り閉位置に保持され、ハンドルが掛金体と基体に依り掛止される。
基体と掛金体にバネ受体が直接設けられ、両バネ受体間に圧縮バネが介設され、両バネ受体間に圧縮バネを囲繞して保持するバネ筒体が設けられているので、部品点数が減少すると共に、バネ受体が揺動する事がない。
【０００６】
【実施例】
以下、本発明の実施例を、図面に基づいて説明する。
図１は、本発明の実施例に係るハンドル掛金装置を示す正面図。図２は、図１の背面図。図３は、閉状態を示す図１の縦断側面図。図４は、開放状態を示す図３と同様図。図５は、要部を破断して示す図１の側面図。図６は、バネ筒体の斜視図である。
ハンドル掛金装置１は、基体２、掛金体３、バネ受体４，５、圧縮バネ６、バネ筒体７とからその主要部が構成されて居り、例えばバン型車両や海上コンテナの後部や側部に設けられた観音開扉の開閉用のハンドルＨを掛止する際に用いられ、掛金体３を閉位置に保持する為の錠手段８を図１の鎖線位置に備えたものと、これを省略したものとがあり、この例では、省略したものにしてある。
基体２は、ハンドル掛金装置１の基本部分を為すもので、この例では、平面舟型を呈し、上側には左右の長孔９が、上側寄りには左右の貫孔１０が、その内側には上方が開放した左右のＵ型凹所１１が、中程には掛金体３の下半を収容する収容腔１２が、その外側には後方が開放した半円状を呈する左右の軸受１３が、下側には貫孔１４が夫々形成されている。貫孔１４は、弾性体で作製されたキャップ１５に依り閉塞されている。
掛金体３は、基体２に対して閉位置から開位置まで回動可能に設けられたもので、この例では、鉤型を呈し、上側には左右に貫通する長孔１６が、上側寄りには後方が開放したＣ型凹所１７が、中程には左右に貫通する軸孔１８が、下側には後方と下方が開放したバネ収容腔１９が夫々形成されている。軸孔１８には、支軸２０が挿通されてその左右外突部分が基体２の軸受１３に嵌合される。
バネ受体４，５は、基体２と掛金体３に設けられたもので、この例では、バネ受体４は、平面Ｈ型で側面略Ｚ型を呈し、左右の折曲片２１と、これらを繋ぐ連結片２２と、これの上側に形成された左右の掛止片２３を備えている。折曲片２１は、四つのビス２４に依り基体２に取付けられ、その上側で支軸２０を押さえる様にしてある。連結片２２の上側中間には、圧縮バネ６の下側が当合される。掛止片２３は、掛金体３が開位置以上に回動するのを阻止する。バネ受体５は、掛金体３の後側に設けられて中間がバネ収容腔１９に臨む左右方向のノックピンにしてある。
圧縮バネ６は、両バネ受体４，５間に介設されて掛金体３を閉位置又は開位置に保持するもので、この例では、圧縮コイルバネにしてあり、バネ受体４の連結片２２の上側とノックピンであるバネ受体５との間に介設されている。而して、バネ受体５と圧縮バネ６の接触点Ａが、バネ受体４の連結片２２と圧縮バネ６の接触点Ｂと支軸２０の中心Ｃを結ぶ線Ｄに対し、互いに対向する位置に移動して掛金体３を閉位置又は開位置に保持する様にしてある。
バネ筒体７は、両バネ受体４，５に離脱不能に掛合されて圧縮バネ６を囲繞して保持するもので、この例では、四角筒状を呈し、平板をプレスして作製され、上側にはノックピンであるバネ受体５に掛合される半円状の左右の切欠２５が、下側にはバネ受体４の連結片２２の上側に掛金体３の回動に支障がない様に掛合される半円状の左右の切欠２６が夫々形成されている。バネ筒体７は、圧縮バネ６に外遊嵌されてこれが座屈しない様に保持する。
【０００７】
次に、この様な構成に基づいて組立要領並びに作用を述解する。
支軸２０が掛金体３の軸孔１８に挿入されてその左右が掛金体３から外突される。掛金体３の上半が基体２の収容腔１２の後方から挿入されて基体２の上側前方に位置され、支軸２０の左右が基体２の軸受１３に嵌合される。圧縮バネ６がバネ筒体７に挿入され、バネ筒体７の上側の切欠２５がバネ受体５に掛合されると共に、圧縮バネ６の上側がバネ受体５に当合される。バネ受体４の連結片２２の上側が圧縮バネ６の下側に当合されてこれが圧縮されると共に、バネ受体４の連結片２２の上側がバネ筒体７の下側の切欠２６に掛合され、バネ受体４の折曲片２１の上側で支軸２０の左右が押さえられ、バネ受体４が四つのビス２４に依り基体２に取付けられる。
バネ受体４は、圧縮バネ６の一方を支持するだけでなく、支軸２０を基体２に取付けて基体２と掛金体３とを回動可能に合体させる機能をも兼備している。従って、この様なバネ受体４の採用に依って組立が更に簡便化される。
図３の状態から、掛金体３の下側を後方に押したり掛金体３の上側を前方に引いたりして、図４に示す如く、掛金体３が開位置に回動されると、掛金体３の後側がバネ受体４の掛止片２３に当合されてそれ以上の回動が阻止され、バネ受体５と圧縮バネ６の接触点Ａがバネ受体４の連結片と圧縮バネ６の接触点Ｂと支軸２０の中心Ｃを結ぶ線Ｄより後方に位置され、掛金体３が圧縮バネ６に依り開位置に保持され、ハンドルＨを掛金体３のＣ型凹所１７と基体２のＵ型凹所１１から離脱できる。
図４の状態から、ハンドルＨが基体２のＵ型凹所１１に落込まれると、図３に示す如く、掛金体３が閉位置に回動され、掛金体３の鉤部が基体２に当合されてそれ以上の回動が阻止され、バネ受体５と圧縮バネ６の接触点Ａがバネ受体４の連結片２２と圧縮バネ６の接触点Ｂと支軸２０の中心Ｃを結ぶ線Ｄより前方に位置され、掛金体３が圧縮バネ６に依り閉位置に保持され、ハンドルＨが掛金体３のＣ型凹所１７と基体２のＵ型凹所１１に依り掛止される。
基体２と掛金体３にバネ受体４，５が直接設けられ、両バネ受体４，５間に圧縮バネ６が介設され、両バネ受体４，５間に圧縮バネ６を囲繞して保持するバネ筒体７が設けられているので、部品点数が減少すると共に、バネ受体４，５が揺動する事がない。従って、組立に多くの手間と時間が掛からず、容易に行なえる。
【０００８】
尚、バネ筒体７は、先の実施例では、四角筒状であったが、これに限らず、例えば円筒状や四角以外の多角筒状でも良い。
錠手段８は、先の実施例では、省略していたが、これに限らず、例えば備えていても良い。
【０００９】
【発明の効果】
以上、既述した如く、本発明に依れば、次の様な優れた効果を奏する事ができる。
（１）基体、掛金体、バネ受体、圧縮バネ、バネ筒体とで構成し、とりわけ、基体と掛金体にバネ受体を直接設け、両バネ受体間に圧縮バネを介設し、両バネ受体間に圧縮バネを囲繞して保持するバネ筒体を設けたので、部品点数が減少すると共に、バネ受体が揺動する事がなく、組立が容易に行なえる。
