Description
Claims (7)
- 針ハブから突設された針が挿通される針孔を先端部分に有する針先カバーが、該針に外挿されて針軸方向で移動可能に設けられており、該針先カバーを針先よりも先端側へ移動させることで該針先が覆われる針組立体において、
前記針に対して固定的に設けられて針軸方向に延びる固定側ガイドと、前記針先カバーに一体的に設けられて長さ方向に延びる移動側ガイドとによってガイド機構が構成されており、
該ガイド機構は、該針先カバーの先端側への移動によって、該針先カバーを該針の基端側から先端側に向かって該針と非接触な状態を維持しつつ案内すると共に、
該ガイド機構は、該針先カバーの先端側への更なる移動によって、該針先カバーの先端部分が該針先を超えた位置で該針の中心軸から前記針孔が外れる方向へ該針先カバーを段差状の軌跡をもってずらして該針先の該針孔への接触を回避しつつ該針先を覆う位置へ該針先カバーを案内するものであることを特徴とする針組立体。 - 前記ガイド機構において、前記針先カバーが前記針の先端側に向かって該針の中心軸に対する傾斜方向へ案内されることで、該針の中心軸から前記針孔が外れる方向へ該針先カバーがずらされるようになっている請求項1に記載の針組立体。
- 前記固定側ガイドが針軸方向に延びる案内溝を有している一方、
前記移動側ガイドが該案内溝に案内される長手の案内ロッドを有していると共に、
該固定側ガイドの該案内溝と該移動側ガイドの該案内ロッドとにそれぞれ段差状部が設けられており、該案内溝に対して該案内ロッドが前記針の先端側に向かって針軸方向に案内されつつ移動させられて該案内溝の該段差状部の位置に該案内ロッドの該段差状部が至ることで該針の中心軸から前記針孔が外れる方向へ前記針先カバーが移動されるようになっている請求項1又は2に記載の針組立体。 - 前記案内ロッドが前記案内溝に嵌め入れられて針軸方向に案内されるようになっていると共に、該案内ロッドの前記段差状部よりも前記針の先端側が針軸方向に直線状に延びている請求項3に記載の針組立体。
- 前記針先カバーが前記針先を越えた位置において、前記針の中心軸から前記針孔が外れる方向へ該針先カバーが該針に対して傾動せずに並進移動するようにされている請求項1〜4の何れか1項に記載の針組立体。
- 前記固定側ガイドが針軸方向に延びる案内溝を有している一方、前記移動側ガイドが該案内溝に案内される長手の案内ロッドを有していると共に、
前記針先カバーが前記針先を覆う位置へ移動することで該固定側ガイドと該移動側ガイドとが相互に係止されて該案内ロッドの前記針の基端側への後退移動を阻止する完了位置ロック機構が設けられている請求項1〜5の何れか1項に記載の針組立体。 - 前記針先カバーを前記針の中心軸から前記針孔が外れる方向へずらした位置から更に該針の先端側に所定距離移動させて前記針先を覆う位置へ移動させることにより、該針先カバーが該針先を覆う位置で、前記完了位置ロック機構により前記固定側ガイドと前記移動側ガイドとが相互に係止されるようになっている請求項6に記載の針組立体。
