PIPING MEMBER AND RAIN GUTTER SYSTEM
To provide a piping member and a rain gutter system capable of stably promoting the action of a siphon phenomenon.SOLUTION: A piping member 5 constitutes a part of a down-pipe 3 of a rain gutter system 1 which uses a siphon phenomenon for draining rainwater. The piping member 5 comprises: a straight pipe part 51 which defines at least a part of a flow path 30 of the down-pipe 3; and a discharge part 52 which is connected to the straight pipe part 51 and is disposed in the flow path 30. The discharge part 52 has: an opening 521 which has a flow path area smaller than that of the straight pipe part 51; and a guide surface 522 which guides rainwater passing through the opening 521 in a direction approaching a center axis C1 of the straight pipe part 51.SELECTED DRAWING: Figure 1
【課題】サイフォン現象による作用を安定的に促進させることができる、配管部材及び雨樋システムを提供する。【解決手段】配管部材５は、雨水の排水にサイフォン現象を利用する雨樋システム１の竪樋３の一部を構成する。配管部材５は、竪樋３の流路３０の少なくとも一部を規定する直管部５１と、直管部５１に結合されて流路３０に配置される吐出部５２と、を備える。吐出部５２は、直管部５１より流路面積が小さい開口５２１と、開口５２１を通過する雨水を直管部５１の中心軸Ｃ１に近付く向きに誘導するガイド面５２２と、を有する。【選択図】図１
