Description

[Detailed explanation of the idea] The present invention relates to rain gutters.

Conventional rain gutters are attached to the eaves, and dirt and sand from the roof may flow into them, but during light rain, the flow rate of rainwater is slow.
Sediment and other debris sometimes accumulated at the bottom of the rain gutter.

In addition, the flow gradient of rain gutters is kept to about 1/200 so as not to spoil the aesthetic appearance of the house, so dirt and sand often accumulates at the bottom of the gutters, clogging them and impairing their drainage function. It was.

The present invention overcomes the above-mentioned conventional drawbacks.

Next, an example of the present invention will be explained with reference to the drawings.

The elongated rain gutter A has substantially rectangular tube-shaped ears 2, 2 on both sides of a gutter-like body 1 having a substantially rectangular groove shape.

A partition plate 3 extending diagonally upward from the bottom of the gutter-like body 1 along the longitudinal direction of the gutter-like body 1 is erected, and the internal space of the gutter-like body 1 is divided into two compartments 10. by the partition plate 3. Divided into 11
One compartment 10 is reduced in size as it approaches the bottom.

The upper end of the partition plate 3 is lower than the upper end of the side wall 13 of one compartment 10, and is provided so as not to come into contact with the inner surface of the other side wall 14.

A bent portion 4 is provided in the upper end of the partition plate 3 in the horizontal direction.

Rain gutter A is connected by gutter joint B.

In the gutter joint B, the gutter-like body 5 is formed into a substantially square groove shape, and ear receivers 6, 6 are formed on both sides.

A partition plate 7 is erected from the bottom of the gutter-like body 5, and the partition plate 7
The board surface is inclined.

Clamping pieces 8, 8 are provided at intervals from the gutter-like body 5 and the partition plate 7.

When installing these rain gutters A and gutter joints B along the eaves 9, they are installed so that the partition plate 3 is inclined and approaches the eaves 9.

During rainy weather, rainwater flows down from the roof and flows from the eaves 9 to the rain gutter A.
from the partition plate 3 into the outer compartment 10.

The gutter-like body 1 is partitioned by the partition plate 3, and the compartments 10 outside the partition plate 3 are sandwiched at the bottom, so even in light rain, the flow rate of rainwater is high, and dirt, etc. accumulates at the bottom. It is washed away without any problem.

However, when it rains heavily and the flow rate of rainwater becomes large, the rainwater passes over the partition plate 3 and flows through the compartment 11 inside the partition plate 3, and does not overflow from the gutter-like body 1.

During heavy rain, the flow rate becomes large and no earth and sand accumulates at the bottom of the gutter-like body 1.

The bent part 4 of the partition plate 3 prevents rainwater from entering the inner compartment 11 from the partition plate 3 during light rain.

The fact that the partition plate 3 is erected from the bottom of the gutter-like body 1 means that
The long rain gutter A has improved strength against bending, does not bend and deform even if the flow rate of rain ice becomes large, and the number of supporting metal fittings supporting the rain gutter A can be reduced.

The rain gutter A is connected by the gutter joint B having the partition plate 7, so that rainwater in the outer compartment 10 from the partition plate 3 of the gutter-like body 1 does not leak from the partition plate 3 to the inner compartment 11. Instead, it flows straight to the drain of the rain gutter.

The shape of the gutter-like body of the rain gutter is not limited to the above-mentioned substantially rectangular groove shape, but also includes those having a substantially semi-cylindrical cross section.

Since the rain gutter of the present invention has the above-described structure, the flow rate of rainwater is high even in light rain, and dirt and sand do not accumulate at the bottom of the gutter.

Also, during heavy rain, rainwater flows through both sides of the partition plate and does not overflow from the rain gutter.

Furthermore, by erecting the partition plate from the bottom of the gutter-like body, the strength against deflection of the rain gutter can be improved, and the number of supporting metal fittings can be reduced to simplify construction.

Claims (1)

[Scope of utility model registration request] A partition plate extending obliquely upward from the bottom of the trough-like body is installed vertically along the longitudinal direction of the trough-like body, and the space inside the trough-like body is divided into two compartments by the partition plate. The width of the chamber becomes narrower as it approaches the base, b, and the upper end of the partition plate is slightly lower than the upper end of the side wall of the trough-like body constituting the one compartment, and does not touch the inner wall surface of the trough-like body. A rain gutter made like this.
