Description

【考案の詳細な説明】（技術の分野）本考案は家屋の軒下に施工する角筒状の呼び樋
に関するものである。[Detailed Description of the Invention] (Field of Technology) The present invention relates to a rectangular tube-shaped gutter constructed under the eaves of a house.

（従来技術と問題点）集水器に集められた雨水は軒下にほぼ水平に施
工した呼び樋を通して竪樋に導びかれて地上に排
水される。(Prior art and problems) Rainwater collected in a water collector passes through a gutter constructed almost horizontally under the eaves, is led to a vertical gutter, and is drained to the ground.

第４図は従来例による呼び樋４の斜視図を示す
が、銅板等の金属薄板を角筒状に折曲形成した呼
び樋４の水下側の端部には材料厚程度の段差を設
けて一段縮径した嵌合端部４１が延設されてい
る。 FIG. 4 shows a perspective view of a conventional gutter 4. The gutter 4 is formed by bending a thin metal plate such as a copper plate into a rectangular tube shape, and the lower end of the gutter 4 is provided with a step approximately equal to the thickness of the material. A fitting end portion 41 whose diameter is reduced by one step is extended.

この嵌合端部４１を他の呼び樋やエルボの水上
側端部に内嵌して接続するが、嵌合端部４１の外
面と他の呼び樋４の水上側端部の内面とは水密性
を高めるため嵌合した時の隙間は極力少なくして
なり、そのため両者を嵌合接続する際に嵌合し難
いものであつた。 This fitting end 41 is connected by fitting internally into the above water side end of another pipe or elbow, but the outer surface of the fitting end 41 and the inner surface of the water above end of the other pipe 4 are watertight. In order to improve the performance, the gap when they are fitted is made as small as possible, which makes it difficult to fit them together.

特に金属製呼び樋の場合は材料厚が0.4mm程度
と薄いため嵌合し難いものであつた。 Particularly in the case of metal pipes, it was difficult to fit them because the material was as thin as about 0.4 mm.

（考案の目的）本考案は上記の問題点を解決し、嵌合が容易で
あり又呼び樋の内部をほぼ水平に流れる雨水を阻
害することなく流下できるような呼び樋を提供す
るものである。(Purpose of the invention) The present invention solves the above problems and provides a gutter that is easy to fit and allows rainwater to flow almost horizontally inside the gutter without being obstructed. .

（考案の構成）第１図ないし第３図は本考案の一実施例である
呼び樋を示す。(Structure of the invention) Figures 1 to 3 show a gutter which is an embodiment of the invention.

金属薄板を折曲形成した角筒状の呼び樋１は水
上側端部に軒樋３を施工した集水器２と接続さ
れ、水下側の端部には材料厚程度の段部１４を介
して縮径した嵌合端部１１が延設されている。 A rectangular pipe-shaped gutter 1 formed by bending a thin metal plate is connected to a water collector 2 in which an eave gutter 3 is constructed at the end above the water, and a stepped portion 14 of approximately the thickness of the material is provided at the end below the water. A fitting end portion 11 having a reduced diameter extends therethrough.

この縮径した嵌合端部１１を形成することは呼
び樋１どうしを嵌合接続した時に外面が平担とな
り外観も良好であり、また嵌合する深さも一定に
保てるものである。 By forming the fitting end portions 11 with a reduced diameter, when the pipes 1 are fitted and connected, the outer surfaces are flat and the appearance is good, and the fitting depth can also be maintained constant.

又この嵌合端部１１の先端部は底面１３以外を
内方に傾斜をつけて折曲してテーパー部１２を形
成し、このため先端部分がやや細くなつて他の呼
び樋１などに内嵌し易すくなるものであり、又底
面１３の先端は折曲すると雨水やゴミなどが滞溜
して腐蝕の原因となるため第３図の側面断面図に
示す如く平坦にして雨水の流れを良好にしている
ものである。 Also, the tip of the fitting end 11 is bent inwardly except for the bottom surface 13 to form a tapered portion 12, so that the tip is slightly tapered and can be inserted into other pipes 1, etc. It is easy to fit in, and if the tip of the bottom surface 13 is bent, rainwater and dirt may accumulate and cause corrosion, so it should be flattened to prevent the flow of rainwater, as shown in the cross-sectional side view of Figure 3. This is what makes it good.

（考案の効果）以上の如く本考案に係る呼び樋は水下側の嵌合
端部の先端が内側に折曲したテーパー形状となつ
ているため施工するに際して他の呼び樋やエルボ
などと嵌合接続が行ないやすく作業も迅速に行な
えるものである。(Effects of the invention) As described above, the taper according to the present invention has a tapered shape in which the tip of the fitting end on the underwater side is bent inward, so it does not fit with other pipes or elbows during construction. It is easy to connect and work can be done quickly.

又テーパー形状も底面部分は平坦となつている
ため雨水の流れを阻害する恐れもないものであ
り、特に材料厚の薄い金属製雨樋の場合はその効
果も大なるものである。 Also, since the tapered shape has a flat bottom, there is no risk of obstructing the flow of rainwater, and this effect is particularly great in the case of thin metal rain gutters.
