FUNNEL AND SIPHON RAIN GUTTER SYSTEM
To provide a funnel that makes it easier to obtain a sufficient drainage capacity by siphon phenomenon.SOLUTION: A funnel 16 that connects an eaves gutter 11 with a down pipe comprises a body part 17 having an upwardly opened recess 17a extending along the horizontal surface and having both ends in the direction along the horizontal surface connected to an eaves gutter, a first diameter reduced part 18 connected to a chute 24a formed in a bottom wall part 24 of the body part and having an inner diameter gradually reduced downward, and a large diameter cylinder part 19 connected to the lower end of the first diameter reduced part and extending downward. The inner peripheral surface of a connection part 28 of the first diameter reduced part with the large diameter cylinder part is curved to project toward the inside in a section S1 including an axis line O of the large diameter cylinder part.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した漏斗を提供する。【解決手段】軒樋１１と竪樋とを接続する漏斗１６であって、上方が開口した凹部１７ａが水平面に沿って延び、水平面に沿う方向の両端部が軒樋に連結される本体部１７と、本体部の底壁部２４に形成された落し口２４ａに連なり、下方に向かうに従い漸次内径が小さくなる第１縮径部１８と、第１縮径部の下端部に連なり、下方に向かって延びる大径筒部１９と、を備え、大径筒部の軸線Ｏを含む断面Ｓ１において、第１縮径部と大径筒部との接続部分２８の内周面は、内側に向かって凸となるように湾曲している。【選択図】図２
