Description
本発明は上記事実を考慮して、管継手に対する管体の挿入量が不足した場合においても、止水部材の溝部内における圧力上昇を防止し、止水部材の溝からの脱落、さらには管体の追い差しを可能とする管継手を提供することを課題とする。
本発明の第1の態様に係る管継手は、管体を挿入する管体挿入空間を備える継手本体部と、前記継手本体部に形成される周溝に設置され、前記管体の内周面に当接して止水する止水部材と、前記周溝における前記管体挿入方向奥側の壁面に形成され、前記周溝と前記管体挿入空間とを連通する連通部と、を有することを特徴とする。
本発明の第5の態様に係る管継手の構成によれば、連通部が周方向位置について継手の軸対象に形成されるため、上記した管体の切断精度が低く周方向のいずれかの点で挿入不足がある場合であっても、連通部を前記した管体と止水部材とが非当接となっている部分の近傍に配置することが可能となる。したがって、周溝から管体挿入空間へ水が流出しやすくなり、より確実に止水部材の脱落を防止することができる。
Claims (6)
- 管体を挿入する管体挿入空間を外周側に備える継手本体部と、
前記継手本体部に形成される周溝に設置され、前記管体の内周面に当接して止水する止水部材と、
前記周溝における前記管体挿入方向奥側の壁面に形成され、前記周溝と前記管体挿入空間とを連通する連通部と、を有する
管継手。 - 前記連通部は、前記管体挿入方向奥側の壁面の周方向の一部を切欠いて形成される切欠部とされる、
請求項1記載の管継手。 - 前記切欠部は、前記管体挿入方向と直交する方向において、前記周溝と同じ深さまで切欠かれて形成される、
請求項2記載の管継手。 - 前記連通部は、周方向複数個所に形成される、
請求項1〜3のいずれか1項に記載の管継手。 - 前記連通部は、周方向位置について前記継手の軸対象に形成される、
請求項4に記載の管継手。 - 前記継手本体部は、前記管体挿入方向奥側に仕切壁を介して前記周溝と隣り合う他の周溝を有し、
前記連通部は、前記仕切壁に形成される、
請求項1〜5いずれか記載の管継手。
