Note that the material and size of the first straight pipe section 10 are not particularly limited and can be set arbitrarily.

The second straight pipe part 12 has a second socket part 18 at one end of the pipe for receiving a straight pipe such as a vertical pipe or a horizontal pipe. The second straight pipe portion 12 is configured as a circular straight pipe made of hard polyvinyl chloride, for example. Note that the material and size of the second straight pipe section 12 are not particularly limited and can be set arbitrarily.

The third straight pipe portion 14 is configured as a circular straight pipe made of hard polyvinyl chloride, for example. Note that the material and size of the third straight pipe section 14 are not particularly limited and can be set arbitrarily.
It is preferable that the outer diameter of the first straight tube section 10, the outer diameter of the second straight tube section 12, and the outer diameter of the third straight tube section 14 are the same from the viewpoint of excellent design.

In the bent rain gutter pipe 100, the first end 14a, which is one end in the axial direction of the third straight pipe part 14, is directly connected to the side opposite to the first socket part 16 of the first straight pipe part 10. The first straight tube section 10 and the third straight tube section 14 are connected such that the axis O1 of the first straight tube section 10 and the axis O3 of the third straight tube section 14 intersect.

The angle θ1 between the axis O1 of the first straight pipe section 10 and the axis O3 of the third straight pipe section 14 is preferably 130° or more and 140° or less, and more preferably 134° or more and 136° or less. The angle θ1 is set so that the angle θ3, which will be described later, is greater than or equal to 90° and less than or equal to 92°.
Note that the angle θ1 means the angle between the intersection of the axis O1 and the axis O3, and the smaller angle (inferior angle) among the angles that share the axis O1 and the axis O3.

When viewed from the front of the first straight pipe section 10 and the third straight pipe section 14, the outer edge 11a on the inferior angle side of the intersection of the axis O1 and the axis O3 has a polygonal line shape. That is, on the inferior angle sides of the first straight pipe part 10 and the third straight pipe part 14, an angle is formed between the straight ridgeline 10a of the first straight pipe part 10 and the straight ridgeline 14a of the third straight pipe part 14. It is formed.
Note that the front view of the first straight tube section 10 and the third straight tube section 14 means that they are viewed from a direction perpendicular to a plane including the axis O1 and the axis O3.

Similarly, when viewed from the front of the first straight tube section 10 and the third straight tube section 14, the outer edge 11b on the dominant angle side of the intersection of the axis O1 and the axis O3 has a polygonal line shape. That is, on the dominant angle sides of the first straight pipe part 10 and the third straight pipe part 14, an angle is formed between the straight ridge line 10b of the first straight pipe part 10 and the straight ridge line 14b of the third straight pipe part 14. It is formed.

In the bent rain gutter pipe 100, the second end 14b, which is the other end in the axial direction of the third straight pipe section 14, is directly connected to the side opposite to the second socket section 18 of the second straight pipe section 12. The second straight tube section 12 and the third straight tube section 14 are connected such that the axis O2 of the second straight tube section 12 and the axis O3 of the third straight tube section 14 intersect.

The angle θ2 formed by the axis O2 of the second straight pipe section 12 and the axis O3 of the third straight pipe section 14 is the same as the angle θ1, and is set so that the angle θ3, which will be described later, is 90° or more and 92° or less. Ru.
Note that the angle θ2 means the angle between the intersection of the axes O2 and O3 and the smaller angle (inferior angle) among the angles that share the axes O2 and O3.

When viewed from the front of the second straight pipe section 12 and the third straight pipe section 14, the outer edge 13a on the inferior angle side of the intersection of the axis O2 and the axis O3 has a polygonal line shape. That is, on the inferior angle sides of the second straight pipe section 12 and the third straight pipe section 14, an angle is formed between the linear ridgeline 12a of the second straight pipe section 12 and the linear ridgeline 14a of the third straight pipe section 14. It is formed.
Note that the front view of the second straight pipe section 12 and the third straight pipe section 14 means that the second straight pipe section 12 and the third straight pipe section 14 are viewed from a direction perpendicular to a plane including the axis O2 and the axis O3.

Similarly, when viewed from the front of the second straight pipe section 12 and the third straight pipe section 14, the outer edge 13b on the dominant angle side of the intersection of the axis O2 and the axis O3 has a polygonal line shape. That is, on the dominant angle sides of the second straight pipe section 12 and the third straight pipe section 14, an angle is formed between the straight ridge line 12b of the second straight pipe section 12 and the straight ridge line 14b of the third straight pipe section 14. It is formed.

In the curved rain gutter pipe 100, the axis O1 of the first straight pipe section 10, the axis O2 of the second straight pipe section 12, and the axis O3 of the third straight pipe section 14 are on the same plane. Thereby, the bent pipe 100 for a rain gutter has excellent design when viewed from the front.

When the axis O1, the axis O2, and the axis O3 are on the same plane, the angle θ3 between the axis O1 of the first straight pipe section 10 and the axis O2 of the second straight pipe section 12 is 90° or more and 92° or less. Preferably, 91.1° is more preferable. If the angle θ3 is greater than or equal to the lower limit of the range, there will be no reverse slope, and if the angle θ3 is less than or equal to the upper limit of the range, the vertical fit will be good and it will be easy to construct a support for supporting the pipe.
Note that the angle θ3 means the angle between the intersection of the axis O1 and the axis O2, and the smaller angle (inferior angle) among the angles that share the axis O1 and the axis O2.

The bent pipe 100 for a rain gutter can be used by connecting a vertical pipe or a horizontal pipe to the first socket part 16 and the second socket part 18, respectively.
