FUNNEL AND SIPHON RAIN GUTTER SYSTEM
To make it easier to obtain a sufficient drainage capacity by siphon phenomenon.SOLUTION: A funnel 16 comprises a body part 17 extending in the horizontal direction and having ends connected with an eaves gutter 11, a suspended cylinder part 18 extending downward from a chute 24a formed in a bottom wall part 24 of the body part 17, and a net member 50 overlapping with the chute 24a in a plan view of the body part 17. The suspended cylinder part 18 comprises a large diameter part 19 connected to the opening peripheral part of the chute 24a in the bottom wall part 24, a diameter reduced part 20 connected to the lower end of the large diameter part 19 and whose diameter is reduced downward, a small diameter part 21 connected to the lower end of the diameter reduced part 20, a first connection part 29 for connecting the large diameter part 19 with the diameter reduced part 20, and a second connection part 30 for connecting the diameter reduced part 20 with the small diameter part 21. The second connection part 30 is formed in a curve shape projecting to the inside of the radial direction of the suspended cylinder part 18, in a longitudinal section S1 including the axis line of the suspended cylinder part 18, and the opening ratio of the net member 50 in a plan view is 50% or more and 99% or less.SELECTED DRAWING: Figure 2
【課題】サイフォン現象による充分な排水能力を発揮しやすくする。【解決手段】漏斗１６は、水平方向に延び端部が軒樋１１に連結される本体部１７と、本体部１７の底壁部２４に形成された落し口２４ａから下方に延びる垂下筒部１８と、本体部１７の平面視において落し口２４ａに重なる網部材５０と、を備え、垂下筒部１８は、底壁部２４における落し口２４ａの開口周縁部に連なる大径部１９と、大径部１９の下端部に連なり、下方に向かうに従い縮径する縮径部２０と、縮径部２０の下端部に連なる小径部２１と、大径部１９と縮径部２０とを接続する第１接続部２９と、縮径部２０と小径部２１とを接続する第２接続部３０と、を備え、垂下筒部１８の軸線を含む縦断面Ｓ１において、第２接続部３０が、垂下筒部１８の径方向の内側に向けて凸をなす曲線状に形成され、網部材５０の平面視における開口率は、５０％以上９９％以下である。【選択図】図２
