PROBLEM TO BE SOLVED: To provide a rain gutter system capable of applying high drainage suction force and reliably increasing a drainage capacity for draining rain water in an eaves gutter.SOLUTION: A rain gutter system A comprises: an eaves gutter 1; and a down pipe 4 connected to a rainwater chute 2 of the eaves gutter 1. A high drainage mechanism 6 gives the rain gutter system A an increased drainage capacity for draining rain water that flows into the eaves gutter 1. The high drainage mechanism 6 comprises: a water suction pipe 7 having water suction holes 10b for taking the rain water in the eaves gutter 1 therethrough, and being arranged on a bottom surface of the eaves gutter 1 along an extending direction T2 of the eaves gutter 1; and a negative pressure induction pipe 8 having one end connected to the water suction pipe 7, being arranged inside the down pipe 4 through the rainwater chute 2 of the eaves gutter 1, and having a negative pressure induction section 8a which has a smaller flow passage area than the other part of an in-pipe flow passage R through which the rain water taken in from the inside of the water suction pipe 7 flows. A water suction port 10 of the water suction pipe 7 comprises: an opening 10a formed at an end, of the water suction pipe 7, opposite to the other end connected to the negative pressure induction pipe 8; and the plurality of water suction holes 10b formed on a side surface of the water suction pipe 7. An outer diameter of the negative pressure induction pipe 8 is smaller than an inner diameter of the down pipe 4 so as to form clearance between the outer surface of the negative pressure induction pipe 8 and an inner surface of the down pipe 4.SELECTED DRAWING: Figure 1
【課題】高排水吸引力を作用させることができ、確実に軒樋内の雨水の排水能力を向上させることを可能にする。【解決手段】軒樋１の落し口２に接続した竪樋４を備えた雨樋システムＡに軒樋１内に流入した雨水の排水能力を向上させる高排水機構６は、軒樋１内の雨水を内部に取り入れる吸水孔１０ｂを有し、軒樋１の底面上に軒樋１の延在方向Ｔ２に沿って配設される吸水管７と、一端を吸水管７に接続し、軒樋１の落し口２を通じて竪樋４内に配設され、吸水管７の内部から取り入れた雨水が流れる管内流路Ｒの一部の流路面積を小にした負圧誘発部８ａを有する負圧誘発管８とを備え、吸水管７の吸水口１０は、負圧誘発管８と接続される端部の反対側の端部に形成された開口部１０ａと、吸水管７の側面に形成された複数の吸水孔１０ｂとからなり、負圧誘発管８の外径が竪樋４の内径よりも小さく負圧誘発管８の外面と竪樋４の内面との間に隙間を形成する。【選択図】図１
