ELBOW, AND SIPHON RAIN GUTTER SYSTEM
To provide an elbow making rain water smoothly flow down.SOLUTION: An elbow 114 of this invention is installed at a downstream side of a siphon rain gutter system which comprises an eaves gutter and a siphon generating portion for generating siphon phenomenon which includes a cylindrical portion penetrating a water collecting port formed on a bottom face of the eaves gutter. The elbow comprises a bent pipe portion and a receiving port provided at both ends of the bent pipe portion. In the bent pipe portion viewed in a cross section in a plane including a tube axis of the bent pipe portion, curvature radius of an inner wall face of an inner peripheral side is larger than 64 mm and smaller than 100 mm.SELECTED DRAWING: Figure 4
【課題】雨水を円滑に流下させるエルボを提供する。【解決手段】本発明に係るエルボ１１４は、軒樋と、前記軒樋の底面に形成された集水口を貫通する筒状部を備え、且つサイフォン現象を発生させるためのサイフォン発生部と、を備えたサイフォン雨樋システムの下流側に設置されるエルボであって、曲管部と、前記曲管部の両端に設けられた受け口と、を備え、前記曲管部の管軸を含む平面における断面で見たときの前記曲管部において、内周側の内壁面の曲率半径が６４ｍｍよりも大きく、かつ、１００ｍｍよりも小さい。【選択図】図４
