Description

[Detailed explanation of the idea] The present invention relates to a rainwater drainage device.

Conventionally, as shown in Fig. 2, rainwater is collected in a water collector 6' by an eave gutter 8', and is then connected to a discharge pipe 61' of the water collector 6' via an elbow joint 3'. 4'
, and the gutter 2' connected to the gutter 4' via an elbow joint 3'. Both were installed outside the house.

However, such drainage devices installed outside the house are unsightly depending on how you look at them, and are particularly difficult to harmonize with today's modern houses. Concealing it by burying it in the exterior walls of buildings or other suitable locations has become a possibility.

By the way, when a drainage device is buried in this way, it becomes difficult to repair the drainage device easily, so it is naturally required that the drainage device be a device with a high degree of safety that will not cause water leakage due to damage etc. However, the conventional device as described above has a water collector 6' and a pipe 4', and a pipe 4' and a pipe 2'.
Both are elbow joints 3'.

Because it is fixedly connected through 3', it cannot sufficiently absorb the thermal expansion and contraction of the drainage system due to temperature changes, and it may be difficult to install it outside the house, so it is recommended to hide the interior on the exterior wall or other suitable place outside the house. Due to the high temperature caused by the accumulation of internal temperature, especially in the summer, there is a risk of damage due to thermal distortion within a short period of time, resulting in water leakage, and therefore, it is dangerous to bury such drainage devices as they are.

This invention was made in view of the circumstances of the slope,
It is an object of the present invention to provide a buried type drainage device which has an extremely high degree of safety and has no risk of water leakage due to breakage or the like.

Hereinafter, the present invention will be explained in detail with reference to embodiment figures.

FIG. 1 is a cutaway sectional view of the main part of the present invention - an embodiment of the present invention, and as shown in the figure, the present invention drainage device has a cylindrical pipe connected to the upper end of a vertical gutter 2 buried in the wall 1 outside the house through an elbow joint 3. At the same time as connecting the gutter 4, the gutter 4 is installed inside a casing 5 protruding from the wall 1 outside the house, and a socket 41 provided near the closed end of the gutter 4 is connected to the upper wall of the casing 5. The gist is that the discharge pipe 61 of the water collector 6 is loosely inserted and connected through the water collector 51.

According to this embodiment, the casing 5 is a rectangular cylinder with a removable lid 52 that imitates the beams of a house, and is horizontally protruded from the outside wall 1 of the house. is water collector 6
A hole 53 into which a discharge pipe 61 can be loosely inserted is bored.

Inside this housing 5, a cylindrical pipe 4 is installed at its base end (
It is tilted so that the end (the end that connects to the downpipe 2) is located downward, and is movably suspended from the housing upper plate 51 via a plurality of (two in the figure) hanging tools 7, 7. It has interior decoration.

This gutter 4 is a cylindrical body with a much larger diameter than the discharge pipe 61 of the water collector 6, and the discharge pipe 61 of the water collector 6 is loosely inserted into the soil part of the surrounding wall near the closed end. Large diameter socket 41
．． Preferably, the socket 4 is in the form of an elongated hole in the axial direction of the gutter 4.
1 is bored, and the drain pipe 6 of the water collector 6 is inserted into this socket 41.
1 is movably and loosely connected through the hole 53 of the top plate 51 of the casing, while the upper end of the vertical trough 2 is fixedly connected to the base end of the nominal trough 4 via a different diameter elbow joint 3. .

In this case, as the different diameter elbow joint 3 and the downpipe 2, one with a larger diameter than the discharge tube 61 of the water collector 6 is selected and used.
It is desirable that the rainwater flowing into the gutter 4 from the water collector 6 can be drained through the vertical gutter 2 without overflowing from the inlet 41, and in addition, as shown in the figure, the rainwater flowing into the gutter 4 can be drained through the hole 53 of the top plate 51 of the casing.
An elastic tube 9, such as a rubber tube, is inserted between the opening and the socket 41 of the gutter 4, and the upper end flange portion 91 of the elastic tube 9 is adhesively bonded to the upper surface of the top plate 51 of the casing. Upper plate 51
It is desirable that rainwater falling on the housing 5 also flow into the gutter 4 through the elastic cylinder 9, so that rainwater does not accumulate inside the housing 5.

In addition, the discharge pipe 61 of the water collector 6 loosely inserted into the socket 41 of the gutter 4 is adjusted according to the head difference between the eaves gutter 8 and the housing 5.
Place other parts, such as a downspout, on the outlet 4.
1 may be inserted loosely.

Furthermore, the socket 41 of the gutter 4 is not limited to a thank-you hole that is bored directly into the soil surrounding the gutter 4 as in the embodiment shown in FIG. A funnel-shaped socket 41' may be joined to the socket, and the discharge pipe 61 may be loosely inserted into the socket 41'.

In the embodiment, the main body of the water collector 6 protrudes upward from the housing 5 and is completely visible from the outside, but if necessary, the water collector 6 may be concealed as appropriate. A decorative plate (not shown) can be attached to the housing 5, or the water collector 6 can be attached to the housing 5.
By embedding it deep inside, the water collector 6 can be made almost invisible from the outside.

In the drainage system of the present invention constructed as described above, the most conspicuous downpipe 2 and pipe 4 are housed inside the casing 5 that imitates the material of the exterior wall 1 of the house, so the exterior of the house is clean and very stylish. Moreover, most of the distortion caused by thermal expansion and contraction caused by temperature changes is absorbed by the loose connection between the outlet 41 of the drain 4 and the discharge tube 61 of the water collector 6, so it can be used for a long time. As a result, you will almost never have to worry about damage or water leakage.

This distortion can be absorbed when the gutter 4 is movably installed inside by means such as hanging tools 7, 7 as in the embodiment.
It becomes even better.

In addition, as in the embodiment, the pipe 4. Elbow joint 3 and vertical pipe 2
If a pipe with a larger diameter than the drain pipe 61 of the water collector 6 is used, rainwater flowing from the eaves gutter 8 through the water collector 6 and into the gutter 4 will be drained through the vertical gutter 2 without overflowing.
Further, by providing the elastic tube 9 as described above, there are advantages such as eliminating the risk of rainwater accumulating inside the housing 5.

As described above, the drainage device of the present invention is useful with excellent safety, durability, aesthetics, etc. However, in the event that any inconvenience occurs, the lid 52 at the tip of the housing 5 can be removed and a portion of the drainage device can be removed. It is also possible to repair it.
