Description

【0001】
【発明の属する技術分野】
本発明は、パイプの外面に目視確認用の線を引くためのパイプ用マーキング装置に関する。
【0002】
【従来の技術】
パイプの端部を継手等に挿入して接続するときに、パイプが必要な長さ確実に継手等に挿入されたか否かを目で確認する必要がある。そして、その確認は、図4に示すように、パイプ4の外面に目印の線5を引くことによって行なうことができる。すなわち、その線5の位置まで挿入していれば、パイプ4が完全に継手6等に挿入したことが確認できる。しかしながら、従来、パイプの所要位置に目印の線5を簡便に引くことができる装置が存在しなかった。
【0003】
【発明が解決しようとする課題】
そこで、本発明は、パイプの所要位置に目視確認用の線を簡便に引くことができるパイプ用マーキング装置の提供を課題とする。
【0004】
【課題を解決するための手段】
上記課題を解決するために、本発明のパイプ用マーキング装置は、継手6等に端部を挿入して接続するパイプ4の端面7に当接させてパイプ4の周方向へ回転可能な基板部1と、その基板部1に垂直で、基板部1をパイプ4の端面7に当接させた状態でパイプ4の外面に沿ってパイプ4の長手方向へ向いた状態となり、パイプ4の外面の周囲を回転可能なガイド板部2と、ペン先9がパイプ4の外面に接触するようにマーキングペン8を保持可能で、ガイド板部2に対しその長手方向へスライド自在で、かつ、ガイド板部2と共にパイプ4の外面の周囲を回転することにより、保持したマーキングペン8のペン先9でパイプ4の外面に目印の線5を引くことができるペンホルダ部3とを具え、また、継手6等の種類別、かつ、サイズ別にペンホルダ部3の位置を変えるときに、そのペンホルダ部3を位置合わせするための目盛14をガイド板部2に表示するとともに、その目盛14の任意の位置にペンホルダ部3を係止可能としたことを特徴とする、という構成にしたものである。
【0005】
【発明の実施の形態】
以下、図を用いて本発明の実施の形態について説明する。まず、本発明のパイプ用マーキング装置は、基板部1と、ガイド板部2と、ペンホルダ部3を具えている。
【0006】
基板部1は、図2に示すように、パイプ4の端面7に当接させた状態で、パイプ4の周方向へ回転可能としている。
【0007】
ガイド板部2は上記の基板部1に垂直で、基板部1をパイプ4の端面7に当接させると、パイプ4の外面に沿ってパイプ4の長手方向へ向いた状態となる。そして、基板部1をパイプ4の端面7に当接させてパイプ4の周方向へ回転させると、図3に示すように、このガイド板部2もパイプ4の外面の周囲を回転することになる。
【0008】
ペンホルダ部3は、マーキングペン8を、そのペン先9がパイプ4の外面に接触するように保持可能な構造としている。例えば、図示したように、マーキングペン8を差し込み可能な筒体10をガイド板部2に組み付けて、その筒体10の底にペン先9を露出させる開口11を設けた構造にすることがてきる。
【0009】
また、ペンホルダ部3はガイド板部2に対し、その長手方向へスライド自在としている。なお、ガイド板部2は長手方向の溝12を設けて、その溝12にペンホルダ部3をスライド自在に嵌着することができる。また、その溝12の底にはマーキングペン8のペン先9を貫通可能な孔13を設けている。
【0010】
ペンホルダ部3にマーキングペン8をセットし、基板部1をパイプ4の端面7に当接してから、ペンホルダ部3をガイド板部2に対しスライドさせて所要位置で停止させ、その位置で図3に示すようにペンホルダ部3をガイド板部2と共にパイプ4の回りを回転させると、マーキングペン8のペン先9によりパイプ4の外周面に線5を引くことができる。したがって、パイプ4を継手6等に挿入する場合、パイプ4をこの線5の位置まで挿入すればよいことになる。
【0011】
ところで、継手6等の種類やサイズによってパイプ4を挿入する長さは異なってくる。すなわち、継手6等が変ればパイプ4に印す目印の線5の位置も異なることになる。したがって、継手6等の種類とサイズが異なったときに、目印の線5を適正な位置に引くには、継手6等の種類別、かつ、サイズ別に、ペンホルダ部3の位置を変更する必要がある。そのために、ガイド板部2には、図1に示すように、継手6等の種類別に、ペンホルダ部3の位置合わせ用の目盛14を表示している。
【0012】
また、図1に示すように、その目盛14を表示した個所に被係止凹部15を設けるとともに、ペンホルダ部3に一体に弾性変形可能な突片16を設けて、その突片16に、上記の被係止凹部15に係止可能な係止凸部17を設けて、ペンホルダ部3を位置合わせした状態で固定可能としている。なお、図1では、突片16と係止凸部17はスリーレス継手側だけにしか表示されていないが、DV継手側にも勿論設けている。
【0013】
なお、不使用時に、ペンホルダ部3に装着したマーキングペン8のペン先9が乾燥しないように、図1に示すように、そのペン先9に被せるキャップ18をペンホルダ部3に取り付けている。なお、図示したように、キャップ18には細い変形容易な紐状体19を付けて、その紐状体19の先端をペンホルダ部3の羽板部20に接続することができる。
【0014】
【発明の効果】
本発明のパイプ用マーキング装置は上記の通りであり、パイプ4を継手6等に挿入するときに、そのパイプ4の外面に目印の線5を引いて、その目印の線5までパイプ4を挿入することにより、継手6等に対しパイプ4を確実に接続することができる。また、継手6等の種類やサイズが異なっても、ペンホルダ部3の位置を変更できるので、それに対応することができる。
