Abstract
本物品は、例えば布製の消防用ホース同士を着脱自在に連結する雄継手及び雌継手から成る町野式の消防継手に用いられ、消防用ホースを引きずったときに消防継手に外力が加わっても、消防継手が分離しないようにした消防継手保護具である。即ち、本物品は、使用状態を示す一部省略参考断面図に示す如く、消防用ホースの端部にかしめリングを介して取り付けられる消防継手の雄継手を構成する接続金具に外嵌されており、接続金具の外周面に設けた抜け止めリングにより、接続金具の外周面にスライド自在に外嵌した押輪(この押輪は雄継手と雌継手の連結を解除する機能を有する)側への移動が阻止され、消防用ホースを引きずったときに消防継手の連結を解除する押輪に外力が掛からないようにしている。消防継手においては、放水活動を行う際に消防用ホースを引きずることが多く、その際に押輪に外力が加わり、押輪が消防継手を解除する方向にスライドすることがあり、放水中に消防継手が外れるという事故が発生するが、本物品が消防継手に装着されていることにより、消防継手を解除する方向の外力が押輪に掛かることを防ぐことができる。また、本物品は、使用時に消防継手を離脱する際において、押輪をスライドさせるために指の掛かりを容易にする切り欠き部を設けている。This article is used for, for example, a Machino-style fire-fighting joint consisting of a male joint and a female joint that detachably connect cloth fire-fighting hoses to each other. It is a fire-fighting joint protector that prevents the fire-fighting joint from separating. That is, as shown in the partially omitted reference cross-sectional view showing the usage state, this article is externally fitted to the connection fitting constituting the male joint of the fire-fighting joint, which is attached to the end of the fire-fighting hose via a caulking ring. , The retaining ring provided on the outer peripheral surface of the connection fitting allows movement to the push ring (this push ring has the function of disconnecting the male joint and the female joint) that is slidably fitted to the outer peripheral surface of the connection fitting. It is blocked so that no external force is applied to the push ring that disconnects the fire joint when the fire hose is dragged. In fire-fighting joints, the fire-fighting hose is often dragged during water discharge activities, and at that time, an external force is applied to the push wheel, and the push wheel may slide in the direction of releasing the fire-fighting joint. Although an accident occurs in which the fire-fighting joint is disengaged, by attaching this article to the fire-fighting joint, it is possible to prevent an external force in the direction of releasing the fire-fighting joint from being applied to the push wheel. In addition, this article is provided with a notch that facilitates finger hooking in order to slide the push wheel when the fire-fighting joint is detached during use.
