  FIG. 1 and FIG. 2 are a perspective view and a longitudinal sectional view, respectively, showing an embodiment of the rainwater extraction device of the present invention.

  1 and 2 has an insertion port 3 for the upper ridge 2 and a connection portion 5 for connecting to the lower ridge 4 at the bottom of the insertion port 3; A rainwater drainage channel 7 in the form of a rectangular tube in which a rainwater drainage channel 6 extending from the insertion port 3 to the connection part 5 is formed, and a rainwater drainage channel 8 communicating with the rainwater drainage channel 6 of the rainwater drainage unit 7 are formed, A cylindrical rainwater extraction portion 10 having a rainwater extraction port portion 9 communicating with the rainwater extraction flow path 8 is provided at the lower end portion. The rainwater extraction part 10 is connected and integrated with the rainwater drainage part 7 and has a substantially semi-elliptical cross section.

  In the rainwater drainage section 7, the gutter 2 is inserted from the insertion port 3 near the upper end of the rainwater drainage flow path 6. The shape and size of the insertion port 3 are made to substantially match the outer shape and size of the square ridge used as the ridge 2, facilitating the installation of the rainwater draining device 1, and the outer shape and size of the rainwater drainage section 7. In addition, it corresponds to the outer shape and size of the square ridge, minimizing the appearance discomfort with the ridges 2 and 4, and improving the appearance.

  The rainwater drainage 7 has a connecting portion 5 with a gutter 4 at the bottom, a rectangular tube-shaped connecting cylinder 5a having an outer shape and a size corresponding to the outer shape of the gutter 2 extending downward from the bottom. And a cylindrical wall portion 5b extending upward from the bottom into the rainwater drainage portion 7. The outer dimension of the wall 5b is slightly smaller than the inner dimension of the connecting cylinder 5a.

  In the rainwater extraction part 10, a cylindrical rainwater extraction port part 9 extends downward from the bottom. Ribs or grooves 9a are provided on the outer peripheral surface of the rainwater outlet port 9 so that the connecting hose 11 does not come off. The rainwater drainage section 10 and the rainwater drainage section 7 are partitioned while the rainwater drainage flow path 8 and the rainwater drainage flow path 6 are communicated with each other by a weir 12 standing inside from the bottom. A filter 13 having a dust removing member for purifying rain water, a filter medium, and the like is replaceably disposed inside the rain water take-out section 10 partitioned by the weir 12.

  As shown in FIG. 3, such a rainwater extraction device 1 has a lower end portion of the eaves 2 inserted into the rainwater drainage flow path 6 through the insertion port 3 at the upper end of the rainwater drainage portion 7, and the upper end of the eaves 4. The portion is fitted or inserted into the outer side of the connecting tube portion 5 a of the connecting portion 5 and attached between the upper and lower flanges 2, 4. At this time, the lower end portion of the upper ridge 2 is disposed near the upper end portion of the rainwater drainage channel 6. In addition, the rain water take-out port portion 9 at the lower end of the rain water take-out portion 10 is fitted or inserted with the upper end portion of the hose 11 on the outer side, and the rain water take-out portion 10 is inserted into the rain water tank disposed at a proper position. It is communicated via.

  Rainwater drained from the upper ridge 2 flows down to the rainwater drainage section 7. The rainwater that has flowed down does not flow out directly to the rainwater take-out portion 10 because the weir 12 is provided, but accumulates in the rainwater drainage portion 7 due to the presence of the wall portion 5 b that forms the weir 12 and the connection portion 5. When the water surface exceeds the height of the wall portion 5b, rainwater flows into the wall portion 5b, flows out to the lower gutter 4 through the connecting cylinder portion 5a, and is drained. As described above, in the rainwater extraction device 1, the weir 12 is erected from the bottom to partition the rainwater drainage portion 7 and the rainwater drainage portion 10, and the rainwater drainage portion 7 extends upward from the bottom to the connection portion 5. Since the wall portion 5b is provided, the amount of drainage can be controlled in the rainwater drainage section 7, and the rainwater can be drained by adjusting to an appropriate amount in consideration of drainage capacity such as drainage grooves.

  When the surface of the rainwater collected in the rainwater drainage unit 7 exceeds the height of the weir 12, the rainwater overflows and flows into the rainwater extraction unit 10. The rainwater that has flowed into the rainwater take-out section 10 is removed from the dust by the filter 13, filtered and purified, and is led to the rainwater tank through the rainwater take-out opening section 9 as resource water. As described above, in the rainwater extraction device 1, the rainwater drainage unit 7 and the rainwater drainage unit 10 communicate with each other and are partitioned by the weir 12. Therefore, rainwater that is reused as a water resource while securing a certain amount of drainage. The required amount can be taken out. The drainage performance of the troughs 2 and 4 and the water withdrawal performance of the rainwater take-out device 1 are realized satisfactorily.

  Furthermore, in the rainwater extraction device 1, as shown in FIGS. 1 and 2, the upper end of the rainwater extraction portion 10 is inclined downward as it is separated from the rainwater drainage portion 7, and thus the rainwater extraction portion 10 is inclined downward. A lid 14 having a substantially semi-elliptical shape is detachably attached to the upper end of the head. When mounted on the upper end of the rainwater extraction unit 10, the lid 14 is disposed so as to be inclined downward in the same direction as the upper end of the rainwater extraction unit 10.

  Furthermore, in the rainwater extraction device 1, an edge member 15 having an outer shape corresponding to the outer shape of the rectangular rainwater drainage unit 7 is detachably attached to the upper end of the rainwater drainage unit 7. The edge member 15 has a shape and a size corresponding to the outer shape of the ridge 2 and is formed with an opening 16 into which the ridge 2 can be inserted, and the edge member 15 is attached to the rainwater drainage section 7. Then, the opening 16 communicates with the insertion port 3 at the upper end of the rainwater drainage section 7.

  The lid 14 and the edge member 15 are integrally formed. Ribs 17 projecting downward along the outer periphery are formed on the back surface edge of the integrated lid 14 and edge member 15, and can be fitted to the upper ends of the rainwater discharge part 10 and the rainwater drainage part 7. . The rainwater take-out device 1 is generally made of synthetic resin such as polycarbonate, and the lid 14 and the edge member 15 are respectively fitted into the rainwater take-out portion by fitting the ribs 17 into the upper ends of the rainwater take-out portion 10 and the rainwater drainage portion 7. 10. Sufficiently held in the rainwater drainage section 7 and is difficult to remove even when subjected to wind pressure or the like. Of course, the lid 14 and the edge member 15 can be removed, and a jig such as a screwdriver is inserted between the lower end of one of the lid 14 or the edge member 15 and the upper end of the rainwater discharge portion 10 or the rainwater drainage portion 7. It can be easily removed. In some cases, it can be removed by a human finger. When the lid 14 is removed, it is possible to replace the filter 13 disposed inside the rainwater extraction unit 10 and to clean the inside.

  The attachment of the lid 14 and the edge member 15 increases the sense of unity between the rainwater extraction device 1 and the eaves 2, 4. In particular, the attachment of the edge member 15 increases the upper end of the rainwater drainage section 7 to which the eaves 2 are connected. It can be stored beautifully, and the appearance of the rainwater extraction device 1 is improved. Further, the integrated lid 14 and the edge member 15 enable the attachment of the lid 14 to the upper end of the rainwater discharge portion 10 and the attachment of the edge member 15 to the upper end of the rainwater drainage portion 7 at the same time. It becomes simple.

  The lid 14 can also be pivotally supported by the edge member 15 at the end on the edge member 15 side so as to be rotatable up and down. In this case, the exchange of the filter 13 and the cleaning of the inside of the rainwater take-out unit 10 can be performed simply by rotating the lid 14 upward while the edge member 15 is attached to the upper end of the rainwater drainage unit 7, Workability is improved.

  In addition, the lid 14 has a recessed portion 18 that is recessed downward at the upper end portion and is lowered by one step. In the recess 18, a drain hole 19 penetrating the front and back is formed at a position away from the rainwater drain 7. In a state where the lid 14 is attached to the upper end of the rainwater take-out portion 10, the drain hole 19 communicates with the rainwater take-out flow path 8 of the rainwater take-out portion 10.

  On the other hand, the edge member 15 is formed with an inclined surface 20 that is inclined downward toward the opening 16 at the peripheral edge of the upper end.

  Therefore, as shown in FIG. 3, in the rainwater take-out device 1, the rain that falls on the upper surface of the lid 14 during rain falls in the recess 18 of the lid 14 inclined downward in the same direction as the upper end of the rainwater take-out portion 10. 19, and can be drained from the drain hole 19 to the rainwater take-out flow path 8 of the rainwater take-out section 10. Therefore, it is difficult for dripping on the side surface of the rainwater taking-out part 10 to occur, it becomes difficult to cause streaks, and contamination of the side surface of the rainwater taking-out device 1 due to dripping can be prevented.

  In addition, the rain 20 falling on the upper end of the edge member 15 at the time of rain can be caused to flow down toward the opening 16 without being stored on the upper surface of the edge member 15 by the inclined surface 20 inclined downward. As described above, the opening 16 has a shape and a size corresponding to the outer shape of the kite 2, but is usually designed in anticipation of deformation caused by the external environment such as the temperature of the kite 2. It is rare for the ridge 2 to be in close contact with the opening 16, and a slight gap is formed between the opening 16 and the ridge 2, so that the rainwater flowing from the opening 16 through the slight gap is removed from the rainwater drainage section 7. It can be poured down into the insertion port 3 at the upper end. Therefore, rain dripping from the upper end of the edge member 15 does not easily occur, and the side of the rainwater drainage section 7 is less likely to have rain dripping lines, so that contamination of the side surface of the rainwater extraction device 1 can be further prevented.

  The rainwater drainage device of the present invention can be connected not only to the square rods shown in FIGS. 1, 2 and 3, but also to round balls, including the external shape of the rainwater drainage section 7. The outer shape of the connecting portion 5 and the edge member 15 and the shape of the insertion port 3 of the rainwater drainage portion 7 and the opening 16 of the edge member 15 can be appropriate according to the outer shape of the heel, The size of each part can also correspond to the size of the heel.
