DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rainwater storage device that harmonizes well as a part of a house and also functions as a hard gutter.

[0002]

2. Description of the Related Art In recent years, in an urbanized area,
Rainwater that has fallen on houses, parking lots, roads, etc. flows directly into rivers, etc. through gutters, so during the rainy season a large amount of rainwater concentrates on rivers, and in a short time exceeds the capacity of rivers, so-called urban flooding frequently occurs. Is causing.

[0003] On the other hand, in the dry season, water in dams and lakes decreases, resulting in water shortages. In many regions, restrictions on tap water supply are implemented. However, dams have to be newly installed to eliminate such water shortages. Building is becoming practically impossible due to the high construction costs and the lack of construction sites close to the city.

However, in order to create a livable environment and to prevent flooding of rivers, it has been proposed that rainwater not permeate the river during rainfall and permeate the land, or be temporarily stored. The rainwater collected temporarily can be used for irrigation of trees, lawns, flowers, etc. in parks, or for irrigation of garden trees, potted plants, etc. in ordinary households, and also for car washing. Can be. Since tap water is relatively inexpensive in Japan, tap water is also used for irrigation of plants, etc. It will lead to the suppression of type floods.

[0005] Under such circumstances, a rainwater storage device as shown in FIG. 5 has recently been developed. This device has a faucet 10
1 is attached to the support 103
, And cover the lid 104, cut the hard gutter 105 along the outdoor wall of the house, connect the water separator 106,
The water separator 106 and the water storage container 102 are connected by a hose 107.

In the rainwater storage device having such a structure, rainwater falling on the roof of a house flows down a downspout 105 from an eaves gutter (not shown), and a part of the rainwater is distributed to a hose 107 by a water separator 106 on the way. It flows and is stored in the water storage container 102. Therefore, by turning the faucet 101 when necessary, it is possible to take out rainwater from the water storage container 102 and use it effectively.

[0007]

However, the above-mentioned rainwater storage device is difficult to install along the outdoor wall of the house, and in addition, since the water storage container 102 is of a bucket type, the device is conspicuous and may be part of a house. There was a problem that the harmony could not be maintained and there was a sense of incongruity and a large installation space was required. In addition, when the amount of rainwater stored in the water storage container 102 decreases and becomes lighter, there is a concern that the water storage container 102 may fall down in a strong wind.

The present invention has been made in view of the above problems, and has as its object the purpose of being well harmonized as a part of a house, requiring no large installation space, being inexpensive to construct, and having a function as a hard gutter. Another object of the present invention is to provide a rainwater storage device that can also exhibit the above.

[0009]

According to a first aspect of the present invention, there is provided a rainwater storage device for storing water inside a vertically long outer cylinder which is vertically fixed along an outdoor wall surface of a house. The inner bag is connected to the inner bag, and a water pipe for introducing rainwater from the rain gutter is connected to the inner bag, and an overflow pipe is connected to the upper part of the inner bag to take out the faucet and inner bag attached to the outer cylinder. It is characterized by being connected by a pipe for use. Here, "pipe" is a term of a broad concept that includes a hose or a tube similar to a pipe.

When the rainwater storage device having such a configuration is installed,
Rainwater that falls on the roof is introduced from the rain gutter (eave gutter) into the inner bag through a water guiding pipe, and is stored therein. And
When the rainwater in the inner bag is almost full, excess rainwater is drained while overflowing through an overflow pipe. In addition, when the rainwater stored in the inner bag is irrigated with garden trees, potted plants, or the like, or when the faucet is turned on when needed, such as at the time of car washing, water can be taken from the faucet through a water intake pipe. .

[0011] As described above, this device is a rain gutter (eave gutter).
It not only stores rainwater introduced from Japan, but also functions as a hard gutter to drain excess rainwater.
There is no need to provide a hard gutter at the installation location of this device. In addition, this device has a good appearance because the inner bag and pipe accommodated in the outer cylinder are not visible, and the outer cylinder is a vertically long cylinder like a large hard gutter. When it is fixed vertically, it is well-harmonic in appearance as a part of the house, and a large installation space is not required, and the fear of the outer cylinder falling down is also eliminated.

Further, when rainwater is stored by storing an inner bag for storing water inside the outer cylinder as in this apparatus, it is not necessary to manufacture the outer cylinder in a watertight manner. Since the outer cylinder can be manufactured easily and inexpensively, the construction cost can be reduced.

Next, a rainwater storage device according to a second aspect of the present invention is the rainwater storage device according to the first aspect, wherein the water guide pipe is branched sideways on the way, and one of the branched pipes is placed in the inner bag. In addition to the connection, the other pipe hanging down from the branch portion is used as a drain pipe, the tip of which is exposed from the bottom of the outer cylinder, and a closing member is detachably attached to an opening of the tip.

[0014] In such a rainwater storage device, the rainwater which begins to descend and contains a large amount of solids such as leaves, trash and earth and sand flows down to the drain pipe, and when the drain pipe is full of rainwater, the solids thereafter are removed. Since almost no rainwater is stored in the inner bag through one of the side branch pipes, it is possible to prevent leaves, garbage, and soil from accumulating at the bottom of the inner bag, and use clean rainwater. can do. Then, by removing the closing member at the opening at the tip of the drain pipe, the solid matter accumulated in the pipe can be easily removed, so that maintenance is easy.

Further, a rainwater storage device according to a third aspect of the present invention is the rainwater storage device according to the second aspect, wherein a filter is provided at a branch base of one of the pipes connected to the inner bag. is there.

When the filter is installed in the branch base as described above, since solids slightly contained in the rainwater are also removed by the filter, clearer rainwater can be stored and used in the inner bag.

According to a fourth aspect of the present invention, there is provided a rainwater storage device according to any one of the first to third aspects, wherein the surface of the outer cylinder is decorated.

In such a rainwater storage device, the aesthetic appearance is improved by the decoration provided on the surface of the outer cylinder. In particular, if the decoration is in harmony with the house, the sense of unity with the house is enhanced, and the appearance is improved. Is better.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a side view of a rainwater storage device according to an embodiment of the present invention, FIG. 2 is a plan view of the device with a cover plate omitted,
FIG. 3 is a front view of the apparatus with the front plate omitted, and FIG. 4 is a partial cross-sectional view of the apparatus.

In FIGS. 1 to 3, reference numeral 1 denotes a vertically long rectangular outer cylinder, 2 denotes an inner bag, 3 denotes a pipe for guiding water, 4 denotes a pipe for overflow, 5 denotes a pipe for water intake, and 6 denotes a faucet. It is.

The outer cylinder 1 has a front plate 1a, a rear plate 1b and left and right side plates 1c, 1c fixed in a rectangular tube shape with a fastener or an adhesive, and a raised bottom plate 1d is attached to a lower portion thereof. And
A lid plate 1e is attached to the upper end. Left and right side plates 1c,
1c is slightly shorter in vertical dimension than the front plate 1a and the rear plate 1b, and a gap is formed between the lower end of the side plate 1c and the ground G to take out a pipe.

As the front plate 1a, the rear plate 1b, the side plate 1c, the raised bottom plate 1d, and the lid plate 1e, plastic plates such as hard polyvinyl chloride and polyolefin are preferably used.
Wood board, plywood, metal plate, etc. can also be used. In particular, when a plastic decorative board is used as the front panel 1a, the rear panel 1b, and the side panel 1c to form the outer cylinder 1 on the surface of which a decoration such as a pattern or a pattern that matches well with the outdoor wall surface W of the house is formed.
This is preferable since there is an advantage that the sense of unity with the above is improved.

The plastic decorative board is, for example, a decorative board in which a surface layer of an acrylic resin or the like is extruded in two layers simultaneously with a resin base layer of a polyvinyl chloride or the like so as to produce a grain pattern or a pattern. It is preferable that the material layer is foamed at a low foaming ratio. When the outer cylinder 1 is formed using such a plastic decorative board, the surface layer is hardly deteriorated, and the beauty of the outer cylinder 1 is maintained for a long time. There are advantages that can be maintained.

Although the dimensions of the outer cylinder 1 are not limited, it is preferable to form the outer cylinder 1 into a rectangular cylinder having a side length of about 20 to 70 cm. An outer cylinder whose side length is shorter than 20 cm has a shortage of water storage capacity due to a small internal volume, and a side length of 70 cm.
The longer outer cylinder has a disadvantage that it becomes difficult to harmonize with the outdoor wall surface W of the house due to its large bulk and the installation space is widened. If the length of one side is within the above range, it may be formed in a square tube shape having a square cross section, or may be formed in a square tube shape having a horizontally long rectangular cross section. Needless to say, the height of the outer cylinder 1 is set to be slightly smaller than the height from the ground G to the eaves gutter (rain gutter) T of the house.

Inside the outer cylinder 1, an inner bag 2 for storing water having a smaller internal volume than the outer cylinder 1 is accommodated. The inner bag 2 is a water-tight, substantially cylindrical bag made of a soft or semi-rigid synthetic resin or synthetic rubber. The inner bag 2 has a water guide pipe for introducing rainwater from the eaves gutter T. 3 are connected.

The water guide pipe 3 is disposed at an inner corner of the outer cylinder 1 so as not to press the inner bag 2 inward greatly.
A call gutter t for guiding rainwater from the eaves gutter T to the pipe 3 is connected. A cheese joint 3a is provided at a branch portion in the middle of the water guide pipe 3, and the pipe 3 branches laterally.
b and the hanging pipe 3c are connected to the cheese joint 3a.

The lower end of one pipe 3b branched to the side is connected to a connection port 2a formed at the lower part of the inner bag 2, and the lower end of the other pipe 3c hanging from the cheese joint 3a is connected to the bottom plate 1d. It protrudes through. The pipe 3c serves as a drain pipe, and the lower end of the pipe exposed from the bottom plate 1d is bent into an L shape, and a closing member 3d is detachably attached to an opening at the tip end.

A filter (not shown) is provided at a side connection port (connection port for connecting the branched pipe 3b) of the cheese joint 3a, and the filter removes solids such as leaves, dust, earth and sand. Clean rainwater is introduced into the inner bag 2 through the pipe 3b.

A connection port 2 formed at the upper end of the inner bag 2
An overflow pipe 4 bent into an inverted U-shape is connected to b. The pipe 4 is also disposed at an inner corner of the outer cylinder 1 (an inner corner diagonally opposite to the water guide pipe 3) so as not to press the inner bag 2 greatly. It penetrates downward.

Further, a faucet 6 is provided below the front plate 1a of the outer cylinder 1.
The two ends of a water intake pipe 5 are connected to the faucet 6 and a connection port 2c formed below the inner bag 2.

The pipe 3c for drainage, the pipe 3c for drain, and the pipe 4 for overflow are preferably plastic pipes such as hard polyvinyl chloride or metal pipes, but the pipes 3b connected to the inner bag 2 are preferred. It is desirable to use a flexible hose or tube for the water intake pipe 5.

In the rainwater storage device having the above-described structure, the outer cylinder 1 is erected along the wall surface W outside the house, and is fixed so as not to fall down using a suitable mounting bracket (not shown).
A call gutter t is connected to the upper end of the water pipe 3, and a water receiving port 7 a of a drainage pipe 7 formed in the ground is provided at a position where the lower end of the overflow pipe 4 projects. A rainwater basin 7 b is provided in the middle of the drain pipe 7.

When the rainwater storage device is installed in this way, the rainwater that has fallen on the roof flows from the eaves gutter (rain gutter) T to the water guide pipe 3 through the call gutter t, but solids such as leaves, trash, earth and sand, etc. The rainwater that has begun to descend and contains a lot of material flows down to the drain pipe 3c, and when the drain pipe 3c is full of rainwater, the subsequent rainwater containing almost no solid matter passes through the pipe 3b branched to the side. It is introduced into the bag 2 and stored. Therefore, there is no fear that leaves, trash, earth and sand, etc., accumulate in the inner bag 2 and fine solids are removed by the filter provided in the cheese joint 3a. Can be. The solid matter accumulated in the lower part of the drain pipe 3c can be easily removed by removing the closing member 3d at the distal end opening, so that maintenance is easy.

When the clean water stored in the inner bag 2 as described above is turned on when it is necessary to irrigate garden trees, potted plants, or the like, or when washing a car, the faucet 6 is turned on. Water can be taken from the tap 6 through 5.

When the amount of rainfall is large and the rainwater in the inner bag 2 is almost full, the surplus rainwater flows down while overflowing through the overflow pipe 4, and the water receiving port 7a
Flows through the underground drainage pipe 7 and drains into the gutter via the rainwater basin 7b. As described above, the present device not only stores rainwater introduced from the eaves gutter T (rain gutter) in the inner bag 2 but also has a function as a hard gutter for draining excess rainwater. It is not necessary to provide a hard gutter at the installation location.

In addition, the rainwater storage device has a good appearance because the inner bag 2 and the pipes 3, 3b, 3c, 4, 5 accommodated in the outer cylinder 1 are not visible, and the outer cylinder 1 has a large rigidity. Because the surface is decorated with a vertically long tube like a gutter, it harmonizes well with the exterior as part of a house. And since the outer cylinder 1 is erected and fixed using the place where the hard gutter is installed, a large installation space is not required, and the worry that the outer cylinder falls down can be eliminated.

Further, in this rainwater storage device, since the inner bag 2 for storing water is accommodated in the outer tube 1 and rainwater is stored in the inner bag 2, it is not necessary to manufacture the outer tube 1 in a watertight manner. Using the plastic plate or plastic decorative plate described above, the outer cylinder 1
Can be manufactured easily and inexpensively, so that the construction cost can be reduced.

In the above embodiment, the outer cylinder 1 is formed in the shape of a square tube having a square cross section and accommodates one inner bag 2. For example, the outer tube 1 may be a rectangular tube having a horizontally long rectangular cross section. When formed in a shape, the inside of the outer cylinder 1 is divided into a plurality of parts by a partition plate so that the bottom part communicates, the inner bags 2 are accommodated in the respective partition spaces, and the inner bags 2 are connected to each other by a communication pipe. At the same time, the communicating pipe and the faucet 6 are connected by the water pipe 5, and the branch pipe 3 b for guiding water is connected to any one of the inner bags 2, and the water flows into the upper portion of the other inner bag 2. By connecting the pipe 4 for
It is desirable to configure a rainwater storage device. With such a configuration, there is an advantage that it is possible to prevent the inner bag 2 from being bent or entangled with each other, thereby hindering rainwater storage.

Further, the outer tube 1 may be formed into a cylindrical outer tube in place of the rectangular outer tube 1. If necessary, rainwater stored in the inner bag 2 may be taken in by a pump. . As described above, the rainwater storage device of the present invention can accept various design changes.
