Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a gutter joint used for connecting eaves gutters.

(Prior Art) Regarding the connection structure at the corner of the eaves of the eaves gutter provided on the gable roof as shown in FIG. 2 or the capped roof as shown in FIG.
As shown in the figure, the lower end of a sloped eaves gutter 100 disposed along the slope of the roof and one end of a curved gutter 101 disposed at the corner of the eaves are connected via a gutter joint 102, and proposed a structure in which the other end of the curved gutter 101 is connected to a horizontal eave gutter 103 arranged horizontally along the eaves (Japanese Patent Application No. 60-257394 (Japanese Unexamined Patent Publication No. 62-117946)). )).

In this connection structure, rainwater flowing inside the inclined eaves gutter 100 is transferred from the inclined eaves gutter 100 to the gutter joint 1.
02, flows into the curved gutter 101, changes direction by 90 degrees, and flows into the horizontal eave gutter 103.

In this connection structure, the inclined eaves gutter 100 is approximately
It is sometimes installed at an angle of inclination of more than 20 degrees,
There is a drawback that rainwater that has flowed into the curved gutter 101 from the sloped eaves gutter 100 may overflow or scatter from the curved gutter 101.

In addition, as a conventional technology that can be used to prevent rainwater from overflowing from a curved gutter as described above, for example, a comb-shaped water stop plate is fixedly installed inside an ordinary eaves gutter (Jikko Sho 51). Japanese Utility Model Publication No. 57-40535) and one in which comb teeth are integrally formed and erected at the bottom of an ordinary eaves gutter are known.

(Problem to be solved by the invention) However, in the case of such conventional technology, water stop plates and comb teeth are provided in the eaves gutter to stop rainwater. However, there was a problem in that it did not effectively prevent rainwater from overflowing from the curved gutter at the corner of the eaves.

In addition, since the comb teeth are fixed within the eaves gutter,
When the flow rate of rainwater is large, the comb teeth become an obstacle, causing rainwater to overflow and scatter.

(Means for solving the problem) The present invention was made with the purpose of solving the above-mentioned problems. A joint body that connects the lower end of an inclined eaves gutter installed to one end of a horizontal eaves gutter installed at the eaves, and a water stop plate provided inside the joint body perpendicular to the flow direction of rainwater. and the water stop plate is swingable in the direction of flow of rainwater.

(Function) Therefore, the present invention has a water stop plate inside the joint body that connects the lower end of the sloped eaves gutter installed along the slope of the roof and one end of the horizontal eave gutter installed at the eaves. Because of this provision, it is possible to effectively slow down the flow of rainwater at the gutter curved portion at the corner of the eaves, where rainwater tends to overflow.

Further, since the water stop plate is provided to be swingable in the flow direction of rainwater with respect to the joint body, the opening angle of the water stop plate can be varied depending on the flow rate of rainwater.

(Example) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, the configuration of the first embodiment shown in FIGS. 1 to 3 will be described.

The gutter joint 1 of this embodiment is used for a sloped eave gutter 2 that is installed along the slope of a roof, such as a gable roof as shown in Fig. 2 or a capped roof as shown in Fig. 3.
and a horizontal eave gutter 4 disposed at the eaves of the roof are connected via a curved gutter 3, and is composed of a joint body 10 and a water stop plate 20.

This joint body 10 is a variable angle joint made of synthetic resin in which an inclined end portion 11 connected to the lower end of the inclined eave gutter 2 and a horizontal connecting portion 12 connected to one end of the curved gutter 3 are integrally molded. The ears 21 of the inclined eave gutter 2 are formed at the upper ends of the left and right side walls of the inclined end part.
An ear receiving part 111 that fits into the ear receiving part 31 of the curved gutter 3 is formed at the upper end of both left and right walls of the horizontal connecting part 12, and an ear part 121 that fits into the ear receiving part 31 of the curved gutter 3 is formed.

The water stop plate 20 has a support shaft 202 integrally provided at the upper end of the water stop board 201, which is a flat plate shaped approximately along the inner surface shape of the joint body 10, and both ends of the support shaft 202 are horizontally connected. both ears part 12 of part 12
Opposing pieces 122 protruding from 1 and 121, respectively;
122, and the water stop piece 201 is disposed perpendicular to the flow direction of rainwater flowing inside the joint body 10.

One end of the horizontal eave gutter 4 is connected to the other end of the curved gutter 3.

Next, the operation of the first embodiment will be explained.

Rainwater flowing in the inclined eaves gutter 2 due to rainfall flows into the curved gutter 3 through the gutter joint 1, and then flows into the horizontal eaves gutter 4.

At this time, the rainwater that has flowed into the gutter joint 1 from the inclined eaves gutter 2 is slowed down by the water stop plate 20 just before the curved gutter 3, so that the rainwater flows gently into the curved gutter 3. This prevents rainwater from overflowing or scattering from the curved gutter 3.

In addition, since the water stop plate 20 is swingably provided, the opening angle of the water stop plate 20 changes depending on the flow rate of rainwater, and this water stop plate 20 becomes an obstacle, preventing rainwater from overflowing. It is possible to provide a deceleration effect while preventing problems that may lead to scattering.

Next, a second embodiment shown in FIG. 4 will be described.

In describing the second embodiment, the same components as those in the first embodiment are given the same reference numerals, and the explanation thereof will be omitted. Further, regarding the operations, explanations of operations similar to those of the first embodiment will be omitted.

This embodiment is an example in which the mounting structure of the water stop plate 20 is different from the first embodiment, and the ear portion 121 of the horizontal connection portion 12
A bearing member 123 is provided protruding from the bearing member 12 .
The end of the support shaft 202 is rotatably fitted into the bearing hole 124 formed in the bearing hole 3 .

Next, FIGS. 5 to 7 show other examples of water stop plates.

The water stop plate 30 shown in FIG. 5 has a support shaft 301 and a water stop piece 302 formed separately,
is swingable with respect to the support shaft 301, and
It is made of a thick flat plate.

Therefore, by increasing the weight of the water stopper piece 302, it is possible to increase the deceleration effect.

The water stop plate 40 shown in FIG. 6 has a water stop piece 401 formed in a comb-like shape, and the water stop plate 50 shown in FIG.
Water-stopping pieces 501 are formed in a mesh shape, and these are designed to allow rainwater to flow through gaps 402, 502.

Note that the support shafts 403, 503 are formed into elongated plate shapes, and are integrally molded with the water stop pieces 401, 501.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and any design changes or the like that do not depart from the gist of the present invention are included in the present invention. It can be done.

For example, in the embodiment, a mounting structure is shown in which the water stop plate is installed on the ear portion of the joint body, but the water stop plate may be installed between the side walls of the joint body.

In addition, in the example, a gutter joint that connects an inclined eaves gutter and a horizontal eaves gutter via a curved gutter is taken as an example, but it is possible to integrate the gutter with the curved gutter and directly connect the inclined eaves gutter and the horizontal eaves gutter. It may also be applied to L-shaped gutter joints.

(Effects of the invention) As explained above, in the gutter joint of the present invention, because the water stop plate is provided inside the joint body, the rainwater is slowed down in the curved gutter section located at the corner of the eaves. Therefore, overflowing and scattering of rainwater can be effectively prevented.

Furthermore, since the degree of opening of the water stop plate is variable depending on the flow rate of rainwater, problems such as the water stop plate becoming an obstacle and causing rainwater to overflow and scatter can be prevented.
