Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a rain gutter for receiving rainwater flowing from a roof surface and flowing it to the ground surface.

[0002]

2. Description of the Related Art A conventional rain gutter is a utility model application published in Sho 61.
As in the device of "rain gutter with a net-like lid" described in Japanese Patent Publication No. 1234136, a net-like rain gutter lid in which a large number of holes are formed in the upper part of the rain gutter is attached to the rain gutter and rainwater. It is a structure that prevents debris that falls into the gutter from falling into the rain gutter.

[0003]

However, in the conventional "rain gutter with a net-like lid", since many holes are formed in the "net-like lid", the rain gutter passes through the holes into the rain gutter. The fine dust and the like flow into the rain gutter through the holes together with the rainwater, and if used for many years, the fine dust will accumulate.

Further, in order to remove the accumulated dust accumulated in the rain gutter, it is necessary to regularly perform cleaning for removing the dust, which is disadvantageous in that it takes time and effort.

Therefore, according to the present invention, even if it is used for many years, fine dust will not be accumulated in the rain gutter, and even if it is used for a long period of time, dust will not be accumulated in the rain gutter. It is intended to provide a rain gutter that does not require regular cleaning to remove it.

As shown in FIG. 3, a left engaging piece 5a which is curved downward in a semicircular shape is formed at the left end of the lateral support member 5, and a semi-circular downwardly-shaped left engaging piece 5a is similarly formed at the right end thereof. A right locking piece 5b that is curved downward in a circular shape is formed.

As shown in FIG. 3, the guide plate 2 for guiding the flow of rainwater that has fallen on the roof includes an upper vertical portion 2a, a flat portion 2b, a middle vertical portion 2d, an inclined portion 2e, a curved portion 2f, and a lower vertical portion. The portion 2g and the horizontal portion 2h are successively arranged. An introduction piece 2i for introducing rainwater into the rainwater receiver 3 is formed on the horizontal portion 2h so as to project downward to the left.

The V-shaped groove 2c is composed of a middle vertical portion 2d and an inclined portion 2e, and there is an upper right portion of the inclined portion 2e at a position slightly below the horizontal line from the flat portion 2b, and the upper right portion has a semicircular shape. The curved portion 2f is continuously provided.

A lower vertical portion 2g is continuously provided below the curved portion 2f, and a horizontal portion 2h is continuously provided at the lower vertical portion 2g.

That is, the cross-sectional shapes of the horizontal support member 5 and the vertical support member 4a are substantially U-shaped. In this way, the reason why the inside is made hollow is to make the weight of the rain trough 1 for preventing dust invasion lighter.

FIG. 7 is a partial vertical cross-sectional view when the rain trough for preventing dust intrusion according to the present invention is installed on a roof. As shown in FIG. 7, rain 7 falls on the surface of the roof 6 to form rainwater 8 and flows on the curved surface of the guide plate 2, and the introduction piece 2i formed on the guide plate 2 and the rainwater receiver 3 are locked to the right. The long holes formed between the pieces 3b flow down to the bottom surface 3c of the rainwater receiver 3.

The rainwater 8 flowing on the surface of the guide plate 2 has a V-shaped groove 2 even if the rainwater flows a lot due to heavy rain.
When flowing into c, the flow of rainwater weakens, and the rainwater 8 flows down slightly gently on the surface of the curved portion 2f, and then flows along the introduction piece 2i to the bottom surface 3c of the rainwater receiver 3.

FIG. 8 is a plan view of another embodiment of the rain trough for preventing dust intrusion according to the present invention. Rain trough 1 to prevent dust intrusion in this example

FIG. 9 is a cross-sectional view showing the flow of rainwater in the case of another embodiment of the dust trough preventing gutter according to the present invention.
As shown in FIG. 9, the rainwater 8a drops from the plurality of through holes 9 formed in the V-shaped groove 2c to the bottom surface 3c of the rainwater receiver 3.

[0029]

Since the present invention has the above-described structure, even rainwater during heavy rain flows over the surface of the guide plate and is guided into the rainwater receiver, so that it overflows and flows out from the rainwater receiver to the ground surface. It never falls.

Even fine dust mixed in rainwater is deposited on the bottom surface in the rainwater receiver because it is removed before it enters the rainwater receiver from the guide plate while flowing on the surface of the guide plate. There is nothing to do.

Further, since it is difficult for even fine dust to enter the rainwater receiver, it does not accumulate in the rainwater receiver, and even if it is used by being attached to the roof for many years, the rainwater is frequently used. There is no need to clean the inside of the receiver.
