Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rain gutter for collecting rainwater falling on a roof and draining the rainwater.

[0002]

2. Description of the Related Art As shown in FIG. 3, a conventional rain gutter is provided with a water collecting box 3 called "Angko" at an appropriate place of an eave gutter 2 which is laid laterally on the eaves of a roof 1 of a building. The downspout gutter 5 is connected to the drain port 4 opened at the bottom wall of the building via the first elbow 6, and the baffle 5 is further connected to the outer wall 7 of the building via the second elbow 9. It is constituted by being connected to a vertical gutter 8 vertically provided along the side.

[0003]

However, according to the above-mentioned prior art, for example, when heavy rain falls in a building with a large slope such as a three-story house which has been increasing in recent years, etc. However, there is a problem that the drainage from the water collecting box 3 cannot be made in time, and the water overflows from the water collecting box 3 and the eaves gutter 2 and falls directly to the ground.

Also, there is a problem that leaves and the like are liable to be clogged in the vicinity of the drain port 4 of the water collecting box 3 and in the bent flow path in the first elbow 6, so that the drainage from the water collecting box 3 tends to be defective. there were.

The cause of these problems is that there is a bent flow path immediately below the drainage port 4 of the water collecting box 3, and the flow of the water is reduced by the resistance of the bent flow path and the flow line is disturbed. It is considered that smooth drainage from the water collecting box 3 is easily hindered, and for the same reason, leaves and the like are difficult to pass through and are easily clogged.

When the gutter 8 passes through a fog visor that protrudes above the window, it is necessary to avoid this mist visor.
Since the rising gutter 8 is bent outward through a plurality of elbows and again along the outer wall 7, there is a problem that the number of bent flow passages is increased, drainage is further reduced, and labor for installation is increased. Was.

Accordingly, the present invention has been made to solve the above-mentioned problems in the prior art, and it is an object of the present invention to improve drainage from a water collecting box and to prevent clogging of leaves such as leaves in a flow passage. The objective is to prevent overflow from the collection box and eaves gutter.

[0008]

Means for Solving the Problems The means of the present invention for solving the above-mentioned technical problems is to have a horizontal eaves gutter at the eaves of the roof of a building, and to connect the eaves gutter to an appropriate place of the eaves gutter. It has a water collecting box attached, has a vertical gutter connected to the upper end to a drain port 4 opened on the bottom wall of the water collecting box 3, and has a downwardly sloped gutter connected to the lower end of the vertical gutter at the upper end. That is, an upper end is connected to a lower end of the call gutter, and a standing gutter is provided vertically along an outer wall of the building.

When a fog visor is protrudingly provided on the outer wall of the building, it is preferable to provide a vertical gutter to a position below the fog visor to connect with the exhalation gutter.

The rainwater that has flowed from the roof into the water collecting box via the eaves gutter flows down through the vertical gutter from the drain port on the bottom wall thereof, and then drains down through the downwardly sloping gutter and the vertical standing gutter. .

Since the vertical gutter is located immediately below the drainage port of the water collecting box, the water in the water collecting box does not receive a large resistance to the bent flow path between the vertical gutter and the exhalation gutter, and the vertical gutter is not affected. It flows down naturally in a falling shape.

Therefore, the drainage flow from the water collection box increases in flow velocity and is rectified in the vertical gutter, so that it flows smoothly in the drainage port and the vertical gutter of the water collection box, and the drainage performance from the water collection box is greatly improved. To improve.

[0013] Further, the smooth flow of the drainage flow makes it difficult for leaf fall and the like to be caught in the vicinity of the drain outlet and in the bent flow path. Further, even if leaf fall and the like are caught in the bent flow path, the fallen leaf and the like are not caught. However, since the water is swept away by the force of the water flowing down in a vibrating manner from above, it is extremely unlikely that the bent channel will be clogged with fallen leaves or the like.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIG. Eaves gutter 2 laid on the eaves of the roof 1
A water collecting box (an angel) 3 is attached to an appropriate location of the eaves gutter 2 in such a manner that the end of the eaves gutter 2 communicates with the upper part of the side wall. The upper end of a cylindrical vertical gutter 10 having a diameter is connected.

The lower end of the vertical gutter 10 is connected to the upper end of the downdraft gutter 5 via a first elbow 6, and the lower end of the gutter 5 is connected to the second elbow. The upper end of an upright gutter 8 erected along the outer wall 7 of the building is connected via 9.

FIG. 2 shows another embodiment of the present invention, which is configured to be adapted to a case where a fog visor 11 is protruded from an outer wall 7 above a window. By providing the lower part of the mist eaves 11 and connecting it to the exhalation gutter 5, the drainage capacity of the rain gutter is increased, and the installation of the rain gutter is greatly simplified.

The length and diameter of the vertical gutter 10 are appropriately set in accordance with the situation in order to achieve the above-mentioned action. In general, the length and diameter of the vertical gutter 10 are about 20 to 30 cm, and the inner diameter is about 4 to 6 cm. ,
A length of about 25 cm and an inner diameter of about 5 cm are preferred.

[0018]

Since the present invention has the above-described structure, the following effects can be obtained. Since the vertical gutter is located directly below the drainage port of the water collection box, the water in the water collection box falls in the vertical gutter without resistance to the bent flow path between the vertical gutter and the expiration gutter. As the water flows naturally, the flow velocity increases, and the water is rectified in the vertical gutter, so that the water flows smoothly through the drain port of the water collecting box and the vertical gutter to be drained, and the drainage performance from the water collecting box is greatly improved. Therefore, even if the roof has a large inclination or heavy rain falls, overflow from the water collecting box and the eaves gutter is reliably prevented.

Further, the smooth flow of the drainage flow makes it difficult for leaf fall and the like to be caught in the vicinity of the drain port and in the bent flow path between the vertical gutter and the exhalation gutter. Even if the fallen leaves are easily swept away by vigorously and a large amount of flowing water, there is almost no inconvenience that the bent flow passage portion is blocked by clogging of the leaves, etc. It can maintain good drainage.

When a fog visor is protrudingly provided on the outer wall of the building, a vertical gutter is provided to a lower position of the mist visor and connected to the exhalation gutter to avoid the mist protection as in the prior art. Since it is not necessary to protrude the standing gutter to the outside, the bending flow path is reduced,
The drainage performance is improved and the installation time is greatly reduced.
