Description

[Detailed explanation of the idea] The present invention relates to a drainage outlet for draining rainwater from a gutter.

Conventionally, when forming a drainage outlet by installing a drain port at a suitable location at the bottom of a gutter, one of two cylinders with a flange extending outward from the top is screwed into the other, and the flange is aligned with the other. The periphery of the drain was glued on.

However, it is difficult to screw in high places such as roofs, and even if the rim and the bottom of the gutter are glued together, shallow water can sometimes form in areas where the gutter is not fully glued.

The present invention solves the above-mentioned conventional drawbacks, and its gist is that a mesh body having a downwardly curved elastic presser piece on the peripheral edge is installed at the drain port provided at the bottom of the gutter; A plurality of locking pieces are provided at a plurality of places to be inserted into the drain port downward from the peripheral edge of the mesh body, locking protrusions are provided on the locking pieces outward, and a ring-shaped locking piece is inserted downward inward from the upper part of the drain receiving cylinder body. A notch having the same or slightly larger planar shape as the locking protrusion is provided at the inner edge of the inclined plate, and a lower edge of the inclined plate where the notch is not provided is at the inner edge of the inclined plate. It is locked to the locking protrusion so as to be freely rotatable in the circumferential direction around the locking piece, and the upper part of the drain receiving cylinder body is brought into contact with the back surface of the bottom of the gutter, and the drain receiving cylinder body is rotated in the circumferential direction. When moved, the notch portion is aligned with the locking protrusion, and the drain receiving cylinder body is located at the drain opening which can be pulled out downward.

An example of the present invention will be described below with reference to the drawings.

The gutter 1 has a substantially rectangular groove shape, has cylindrical ears 2 on both sides, and has a substantially flat bottom 3.

Reference numeral 4 denotes a mesh body, which is shaped to swell upward, and elastic presser pieces 5, 5 curved downward are provided on the peripheral edge.

Numerals 6, 6 are locking pieces, which are provided at two locations downward from the peripheral edge of the mesh body 4 at appropriate intervals.

At the bottom of the locking pieces 6, 6, locking protrusions 7, 7 are provided facing outward.

The mesh body 4 is installed at a drain port 8 provided at a proper location on the bottom 3 of the gutter 1 to prevent fallen leaves etc. from entering the drain port 8.

The elastic holding pieces 5, 5 abut against the periphery of the drain port 8, and the locking pieces 6
, 6 are inserted through the drain port 8 and protrude downward.

The locking pieces 6, 6 may be integrally formed on the periphery of the drain port 8 of the gutter 1, or may be fixed by adhesive.

Reference numeral 9 denotes a drainage receiving cylinder, and an annular inclined plate 10 is provided downwardly inward from the upper edge.

At the lower edge of the inclined plate 10, two notches 11, 11 are formed which have the same or slightly larger planar shape than the locking protrusions 7, 7.

12 is a downpipe connection part. The lower edge of the inclined plate 10 of the drainage receiving cylinder 9 is locked to the locking protrusions 7, 7 so as to be rotatable in the circumferential direction around the locking pieces 6, 6, and the upper part of the drainage receiving cylinder 9 is connected to the gutter. 1, and when the drain receiving tube body 9 is rotated in the circumferential direction, the notches 11, 11 are brought into alignment with the locking protrusions 7, 7, and the drain receiving tube body 9 can be pulled out downward. A drainage outlet is formed.

To lock the lower part of the inclined plate 10 of the drainage receiving cylinder 9 to the locking protrusions 7, 7 of the locking pieces 6, 6, hold the mesh body 4 from above and hold the drainage receiving cylinder 9. Raise it from

The locking pieces 6, 6 are slightly elastically deformed, and the locking protrusions 7, 7
The lower part of the inclined plate 10 is locked.

When the locking pieces 6, 6 are provided on the mesh body 4 having the elastic holding pieces 5, 5, the elasticity of the elastic holding pieces 5, 5 acts as a force to pull up the locking pieces 6, 6, and the drainage receiving cylinder body The upper part of the gutter 9 serves as an auxiliary member in strong contact with the back surface of the bottom part 3 of the gutter 1.

When it is necessary to disassemble the drainage port and remove the drainage receiving cylinder 9, rotate the drainage receiving cylinder 9, align the locking protrusion 7.7 with the notches 11, 11, and remove the drainage receiving cylinder 9. pull it down.

Rainwater flows from the gutter 1 into the drain port 8, is received by the drain receiving cylinder 9, and flows down to the gutter connected to the gutter connection part 13.

Some of the rainwater enters the back surface of the bottom 3 of the gutter 1 through the drain port 8, but since the upper part of the drainage receiving tube 9 is in contact with the back surface of the bottom 3 of the gutter 1, it does not come off and leak. Flows into 9.

Since the drainage outlet of the present invention is configured as detailed above, it can be attached to the locking protrusion of the locking piece by the elasticity of the inclined plate by simply lifting the drainage receiving cylinder, and it can be attached to the locking protrusion of the locking piece. Work at heights can be done in a short amount of time.

In addition, since the upper part of the drainage receiver body is in contact with the back surface of the bottom of the gutter, even if some rainwater enters the bottom back surface of the gutter from the drain opening, it will not leak outside from the top of the drainage receiver body. Without,
It returns to the inside of the drainage receiving cylinder.

In addition, there is a notch on the lower edge of the inclined plate that has the same or slightly larger planar shape than the locking protrusion, so when it is necessary to disassemble the drain port and remove the drain receiving cylinder, it is possible to By rotating the receiving cylinder, the locking protrusion is brought into alignment with the notch, and the drain receiving cylinder can be pulled out downward.
