[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a rain gutter that drains water from a rain gutter of each house, other rain water receptacles, or rain water from the ground surface.
[0002]
[Prior art]
  Conventionally, rainwater troughs have an inflow cylinder and an outflow cylinder having an inflow side connection port and an outflow port for connecting an inflow pipe and an outflow pipe for rainwater and the like to the peripheral side of the main body. A molded structure was adopted.
[0003]
  However, in this structure, the position of the inlet side outlet and outlet of the dredge body is constant, so when connecting an inflow pipe such as rainwater to the inlet side inlet of the dredge body, Piping has to be done with the position and height in the circumferential direction adjusted to the position, and there is a problem that labor is required for the piping work.
[0004]
  Therefore, without forming the inlet cylinder part integrally on the peripheral side part of the coffin body, after forming the coffin body, the perimeter side part of the coffin body is drilled with an inflow side connection port using a hole saw or the like, and the inflow side connection port is formed. A method of connecting an inflow pipe or an inflow side connection port to the mouth is adopted.
[0005]
  The inflow pipe can be connected to the inflow side connection port by inserting the inflow pipe from the outside of the main body through the packing to the inflow side connection port and connecting the liquid tightly, or by connecting the pipe to the inflow side connection port. The inflow side connection port body is attached and held liquid-tight with packing, etc., and the inflow pipe is connected to the inflow side connection port body, and the height and circumferential position of the inflow side connection port are drained. It can be set as the position according to the piping situation of a pipe, and piping can be performed easily.
[0006]
  Further, a stopper step for positioning the downstream opening end of the inflow pipe is formed on the inner peripheral portion of the inflow side connection port body, and the downstream opening end of the inflow pipe inserted into the inflow side connection port body Is brought into contact with the stopper step portion, so that the drainage smoothly flows without forming a step between the inner peripheral surface of the inflow pipe and the inner peripheral portion of the inflow side connection port body.
[0007]
  In addition, as disclosed in Japanese Patent Laid-Open No. 9-41474, a mud reservoir is provided at the lower part of the dredge body to prevent the outflow pipe connected to the outflow port of the dredge body from being clogged with pebbles or mud. There is also known a rainwater tank having a structure in which a mud reservoir that can be inserted and removed is provided in the mud reservoir so that the removal of mud and pebbles accumulated in the mud reservoir can be easily performed. .
[0008]
[Problems to be solved by the invention]
  However, after forming the rivet body, a hole saw is used to pierce the inflow side connection port on the peripheral side of the heel body, and an inflow pipe or inflow side connection port body is attached to the inflow side connection port. In the case where the mud reservoir is arranged in the mud reservoir, the downstream open end of the inflow pipe connected to the inflow side connection port drilled in the main body or the downstream open end of the inflow connection port body Projecting into the inside of the dredge body, when the mud pool container is taken in and out, the mud pool container is caught on the downstream opening end of the inflow pipe or the inflow side connection port projecting into the dredge body, and mud There was a problem that hindered the operation of putting in and out the storage container.
[0009]
  Furthermore, when the inflow side connection port is drilled with a hole saw in the peripheral side of the conventional dredge body, the height of the inflow side connection port is drilled at a position higher than the outflow port in order to prevent backflow to the inflow pipe of rainwater. In addition, when the inflow side connection port body is attached to the dredge body, the circumferential position of the peripheral side portion is aligned with the connection direction of the inflow pipe so that the drainage from the inflow pipe smoothly flows into the dredge body. In addition, there is a problem in that the inflow side connection port must be perforated and the height position of the inflow side connection port or the circumferential perforation position must be individually measured by the operator during work.
[0010]
