[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage basin having an upwardly-facing inlet, a laterally-facing inlet, and a downwardly-facing outlet.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Utility Model Laid-Open No. 62-12829.
As described in Japanese Patent Publication No. 1 and Japanese Utility Model Publication No. Hei 4-12143, a drainage drain provided with an upward receiving port, a lateral receiving port, and a downward receiving port is known.

[0003]

However, as described in Japanese Utility Model Laid-Open No. 62-128291,
In drainage basins provided with upward, horizontal and downward receiving ports, the direction of the pipe connected to the upward and downward receiving ports is only the vertical direction,
Further, the laterally-oriented receiving port is only in the horizontal direction, and the direction cannot be adjusted in a trivial manner, and there is a disadvantage that it cannot be avoided when there is an obstacle at the time of piping construction.

The present invention has been made in view of such a problem in a conventional drainage basin, and an object of the present invention is to solve the above-mentioned problem and to provide a drop pipe connected to a downwardly-facing receptacle. The purpose of the present invention is to provide a drainage that can be adjusted not only in the vertical direction but also in the vertical direction, and can be avoided even when there is an obstacle during piping work.

[0005]

In order to achieve the above object, the drainage device according to the present invention has an upward receiving port to which an inspection cleaning pipe is connected , a horizontal receiving port to which a drainage pipe is connected , and a drop pipe.
In the drain basin provided with a downward receiving port to which is connected, the pipe wall of the downward receiving port is bulged in the shape of a spherical shell in the middle, and a short pipe is inserted into this receiving port. The outer surface is a spherical surface that fits the inner surface of the tube wall of the spherical shell-shaped port, and the drop
By connecting the tubes through this short tube,
It is characterized in that the top tube can be swung .

[0006] The drainage basin of the present invention is made of a synthetic resin such as polyethylene, polypropylene, hard vinyl chloride resin or FRP, alone or in an appropriate combination, and is lightweight and has high corrosion resistance. Yes, low cost and preferred. For example, an upward-facing port, a lateral port,
The main body of the drainage trough provided with the downward receiving port may be formed by FRP, and the short pipe inserted into the receiving port may be made of hard vinyl chloride resin.

When polyethylene, polypropylene or vinyl chloride resin is used as the material, it is preferable to use a low foam of about 1.2 to 3 times in order to reduce weight and save material.

In the present invention, when a thermoplastic resin such as polyethylene, polypropylene or vinyl chloride resin is used as a material, it can be molded by an injection molding method. May be formed by post-processing such as blow molding.

[0009]

[Action] The drainage wall of the present invention has a downwardly facing tube wall that bulges in the middle of the tube in the middle, a short tube is inserted into this hole, and the outer surface of the short tube is a spherical shell-shaped hole. The drop tube is connected through this short tube.
By this, the drop tube can be swung.
For example, there is a drop in the drainage pipes in two residential lands
If you do, drain the drain pipe in the upper residential area
Connected to the horizontal receptacle of the present invention,
By swinging the drop tube connected to the mouth,
It can be easily connected to an underground drain pipe.

[0010]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view illustrating an example of a usage state of the drainage basin of the present invention. In FIG. 1, reference numeral 1 denotes a drainage of the present invention, which is integrally formed by injection molding using low foaming polyethylene.

Reference numeral 11 denotes an upward receiving port, 12 and 12 denote laterally receiving ports which are orthogonal to each other, 13 denotes a downward receiving port, and the downward receiving port 13 has a halfway bulged partway. , The short pipe 131 is inserted into the downwardly facing receptacle 13, and the short pipe 131 is inserted.
The outer surface of is a spherical surface that fits the inner surface of the tube wall of the spherical shell-shaped port, and the spherical surface of the short tube 131 can slide in the direction of the arrow a in the spherical shell-shaped tube wall of the downward port 13. ing. The short pipe 131 is also formed by injection molding using low-foaming polyethylene.

[Operation of Embodiment] Next, the operation of the drainage basin 1 of the present invention shown in FIG. 1 will be described. In the present invention, an inspection cleaning pipe (not shown) is inserted and connected to the upward receiving port 11 of the drainage basin 1, and a drain pipe in the residential land (not shown) is inserted and connected to the horizontal receiving ports 12 and 12.
The upper end of the drop tube 2 is inserted and connected into the short tube 131 of No.3. The drop tube 2 is a downwardly facing socket 1 integrally with the short tube 131.
3, the center axis BB of the drop tube 2 is aligned with the upward receiving port 11 and the downward receiving port 13 of the drainage device 1 of the present invention.
Can be inclined by about 30 degrees with respect to the central axis A-A passing through.

Although the embodiment of the present invention has been described with reference to the drawings, the specific configuration of the present invention is not limited to this embodiment, and a design change or the like may be made without departing from the gist of the present invention. Anything is included in the present invention. For example, in the illustrated embodiment, two lateral sockets are provided,
The number may be only one, or three or more.

[0014]

[0015]

[Effect of the present invention] The drain wall of the present invention has a downwardly-facing port wall which bulges in the shape of a spherical shell in the middle, and a short pipe is inserted into this receptacle, and the outer surface of the short pipe has a spherical shell shape. A spherical surface conforming to the inner surface of the pipe wall of the receiving port is used.
So that the drop tube can be swung.
The two drains in the residential area
If there is a drain, drain the drain pipe in the upper residential area
Connected to the horizontal receptacle of the water basin, the present invention drains downward
Swinging the drop tube connected to the
It can be easily connected to the drainage pipe in the residential land. or,
If there are obstacles such as gas pipes, electric conduits, and water pipes below the drainage trough of the present invention, these obstacles can be easily avoided by swinging the drop pipe. Therefore, the drainage basin of the present invention is suitable as a drainage basin used when there is a head drop in two residential land drainage pipes.
