Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rain gutter, and more particularly to a rain gutter that atomizes rainwater that has fallen from the eaves and diffuses it to the outside.

[0002]

[Prior art]

 Conventionally, rainwater that has fallen from the eaves is received by a semi-cylindrical eaves gutter and flows in the longitudinal direction, and is also made to flow down to the surface by a cylindrical down gutter.

[0003]

[Problems to be solved by the device]

 Since the conventional rain gutter has a structure that collects and discharges all the rainwater that flows down from the roof, if there is a large amount of rainfall, some rainwater may overflow from the eaves gutter and Even if the amount of rainfall is not small, rainwater may overflow from the eaves if the eaves are clogged with dead leaves. Therefore, in the case of the conventional rain gutter, there is a problem that it is necessary to regularly clean the gutter, and the work is not easy.

The present invention has been made in view of the present situation, and provides a rain gutter in which rainwater does not flow down below the eaves even when the amount of rainfall is large or dead leaves are accumulated. The purpose is to

[0005]

[Means for Solving the Problems]

 As a means for achieving the above-mentioned object, the present invention arranges a plurality of rainwater diffusers at a lower position of the eaves with a narrow interval in the eaves' extension direction, and at least the lower end portion of each rainwater diffuser. Is inclined toward the lower side of the outdoor side.

Further, in the present invention, it is preferable that adjacent rainwater diffusers are partially overlapped with each other in the direction of overhang of the eaves.

Further, it is preferable that the rainwater diffuser is formed of a strip plate material, or is formed by arranging bar members or flat plate members in parallel at a predetermined interval. When the bar members or flat plate members are arranged in parallel In addition, it is preferable that at least the positions of adjacent rods or flat plates of the rainwater diffuser be different from each other.

[0008] Further, it is more preferable that each rainwater diffuser is arranged 10 cm or more below the eaves, and it is more preferable that the upper end of the rainwater diffuser is provided with a rising portion that rises substantially vertically.

[0009]

[Action]

 In the rain gutter according to the present invention, a plurality of rainwater diffusers are arranged below the eaves at a narrow interval in the projecting direction of the eaves. For this reason, the rainwater flowing down from the eaves collides with one of the rainwater diffusers, and part of the rainwater bounced by the rainwater diffuser collides with the rainwater diffuser next to it, and this action also occurs. May be repeated many times.

By the way, since at least the lower end of each rainwater diffuser is tilted obliquely downward to the outside of the room, the rainwater that collides with each rainwater diffuser is guided to the outside of the room at the inclined portion. , Becomes mist and is diffused to the surface. Therefore, unlike rain gutters that have a conventional structure that collects and discharges rainwater, there is no problem that the gutters are clogged and the rainwater overflows, and maintenance is extremely easy.

In the present invention, the rainwater diffusers adjacent to each other are partially overlapped with each other in the erecting direction of the eaves, so that the total amount of rainwater that has flowed down into the installation range of each rainwater diffuser is surely sprayed. It becomes possible to dissipate and dissipate.

Further, by forming the rainwater diffuser with a strip plate material, it is possible to easily manufacture and to obtain a strong rain gutter easily.

Further, by constructing the rainwater diffuser by arranging rods or flat plates in parallel at predetermined intervals, it is possible to almost completely prevent dead leaves and the like from accumulating on the rainwater diffuser. Becomes At this time, at least the positions of the rods or flat plates of the adjacent rainwater diffusers are made different from each other, so that the gap between the rods or the flat plates becomes smaller than that of the adjacent rainwater diffusers. Complemented by flat plate materials, the same or better rainwater atomization effect as when strips are used can be obtained.

Further, by arranging each rainwater diffuser at a position 10 cm or more below the eaves, the rainwater flowing down from the eaves has a large drop energy and collides with the rainwater diffuser, so that the amount of rainfall increases. Even if the amount is small, it is possible to sufficiently atomize and disperse.

Furthermore, by providing a rising portion that rises substantially vertically at the upper end portion of the rainwater diffuser, the rainwater that flows down from the eaves will collide with the rainwater diffuser after entering between the rising portions, It is possible to prevent the problem that the rainwater splashed by the rainwater diffuser is diffused to the outer wall of the building.

【Example】

 Hereinafter, the present invention will be described with reference to the drawings. FIG. 1 shows a rain gutter according to a first embodiment of the present invention. The rain gutter 1 includes a plurality of rainwater diffusers 3 at a position below an eaves edge 2 and having narrow intervals in the eaves' extension direction. These rainwater diffusers 3 are attached to the outer wall 5 of the building via a bracket 4, as shown in FIGS. 1 and 2.

As shown in FIGS. 2 and 3, each of the rainwater diffusers 3 is made of, for example, aluminum and is connected to the rising portion 3a at the upper end that rises substantially vertically and the lower end of the rising portion 3a. And a sloped portion 3b that slopes obliquely downward, are formed in a strip shape with a V-shaped cross section. Adjacent rainwater diffusers 3 are arranged in parallel with each other, as indicated by reference sign OL in FIG. Partially overlaps. As a result, the rainwater 6 (see FIG. 1) that has flowed down into the installation range W of each rainwater diffuser 3 is reliably atomized, and is dispersed as mist-like water droplets 7 toward the ground surface. Has become.

As shown in FIG. 1, the rain gutter 1 having the above structure is installed below the eaves 2, and the vertical dimension H from the eaves 2 is preferably 10 cm or more, more preferably 14 cm or more. Is set to. As a result, the rainwater 6 that has flowed down from the eaves 2 is given a large amount of fall energy, which strongly collides with the rainwater diffuser 3 and can be sufficiently atomized even when the amount of rainfall is small. There is.

Next, the operation of this embodiment will be described. The rainwater 6 from the eaves 2 flows down into the installation range W of each rainwater diffuser 3, but at the upper end portion of each rainwater diffuser 3, as shown in FIG. Since it is provided, the rainwater 6 first falls into the space surrounded by the rising portions 3a, and then collides with the respective inclined portions 3b. For this reason, it is possible to completely prevent the rainwater 6 that hits and bounces off each of the inclined portions 3b from being diffused to the building outer wall 5 side.

By the way, the rainwater 6 that collides with each inclined portion 3b is diffused as it is, or collides with the back surface side of the rainwater diffuser 3 adjacent to each other, and this operation is repeated many times. This will be repeated, but in any case, since the inclined portions 3b are inclined obliquely downward to the outside of the room, the rainwater 6 finally becomes mist-like water droplets 7 in the inclination direction of the inclined portions 3b. Will be dissipated.

However, unlike the rain gutter of the conventional structure that collects and discharges rain water at the eaves gutter, the structure is such that the rain water 6 that has flowed down from the eaves tip 2 is atomized and discharged at that position, so there is a large amount of rainfall. Even in this case, there is no problem that the rainwater overflows from the eaves gutter, and the rainwater 6 can be reliably discharged.

Further, unlike the conventional eaves gutter having a semi-cylindrical shape, since the plate-like rainwater diffuser 3 is arranged in parallel, there is little risk of dead leaves, etc. However, there is no problem that the function as a rain gutter is completely lost, because the atomization function of the accumulated part is slightly reduced. In addition, it is easy to remove the deposit.

FIG. 4 shows a second embodiment of the present invention, in which a rainwater diffuser 13 is used instead of the rainwater diffuser 3 in the first embodiment.

That is, as shown in FIG. 4, the rainwater diffuser 13 is constructed by inclining the strip plate obliquely downward to the outside of the room, and the adjacent rainwater diffusers 13 are denoted by reference numerals in FIG. As indicated by OL, they partially overlap each other in the juxtaposed direction. In other respects, the configuration is the same as that of the first embodiment and the operation is the same.

In the case of the rainwater diffuser 13, however, since it does not have a rising portion at its upper end, the rainwater 6 that hits the rainwater diffuser 13 and rebounds when the amount of rainfall is large, There is a possibility that it will be dissipated to the building outer wall 5 side, but in other respects, the same effects as in the first embodiment can be expected.

FIGS. 5 and 6 show a third embodiment of the present invention, in which a rainwater diffuser 23 is used instead of the rainwater diffuser 3 in the first embodiment.

That is, as shown in FIG. 5, the rainwater diffusing body 23 is composed of rods 24 arranged in parallel at predetermined intervals, and each rod 24 of the adjacent rainwater diffusing body 23 is The positions are shifted so as to complement the gap between the bar members 24 of the other party.

Further, as shown in FIG. 6, the bar member 24 of each rainwater diffuser 23 is provided with a rising portion 24a which rises substantially vertically and a lower end of the rising portion 24a, which is connected to the lower end of the outdoor side obliquely. The rainwater diffuser 23, which is formed in a dogleg shape from the inclined portion 24b that is inclined toward the side, partially overlaps in the juxtaposed direction, as shown by the reference character OL in FIG. . In other respects, the configuration is the same as that of the first embodiment and the operation is the same.

In the case of this rainwater diffuser 23, however, since there is a gap between the rods 24, it is possible to almost completely prevent the accumulation of dead leaves and the like. Since the rods 24 are arranged at different positions so as to complement the gaps between the opposing rods 24, it is possible to expect the same effect as that of the first embodiment.

In the third embodiment, the rainwater diffusing body 23 is formed by using the rods 24. However, the rainwater diffusing body 23 is formed by arranging flat plate materials at predetermined intervals. You may do it.

Further, in each of the above-mentioned embodiments, the rainwater diffusers 3, 13, 23 adjacent to each other are partially overlapped in the arranging direction. However, if the gaps are narrow, the rainwater diffusers 3, 13 and 23 are overlapped. Even if it does not exist, the same effect as when overlapping is expected.

[Effect of device]

 As described above, according to the present invention, a plurality of rainwater diffusers are arranged at a lower position of the eaves at a narrow interval in the eaves overhang direction, and at least the lower end portion of each rainwater diffuser is slanted to the outside of the room. Since it is inclined downward, unlike conventional rain gutters that collect and discharge rainwater in eaves gutters, even when there is a large amount of rainfall or when dead leaves are accumulated, The rainwater can be treated reliably without any problems such as the complete loss of rain gutter function. In addition, maintenance is easy.

In the present invention, the rainwater diffusers adjacent to each other are partially overlapped with each other in the overhanging direction of the eaves, so that the total amount of rainwater that has flowed down into the installation range of each rainwater diffuser is surely fogged. It can be turned into dissipated.

Further, by forming the rainwater diffuser with a strip plate material, a rain gutter that is easy to manufacture and strong can be easily obtained.

Further, by constructing the rainwater diffuser by arranging rods or flat plates in parallel at predetermined intervals, it is possible to almost completely prevent dead leaves and the like from depositing on the rainwater diffuser. It At this time, at least the positions of the rods or flat plates of the adjacent rainwater diffusers are made different from each other, so that the gap between the rods or the flat plates becomes smaller than that of the adjacent diffusers. The effect of rainwater atomization is the same as or better than the case of using strips.

Further, by arranging each rainwater diffuser at a position 10 cm or more below the eaves, the rainwater flowing down from the eaves has a large drop energy and collides with the rainwater diffuser, so that the amount of rainfall increases. Even if the amount is small, it can be sufficiently atomized and released.

Furthermore, by providing a rising portion that rises almost vertically at the upper end portion of the rainwater diffuser, the rainwater that flows down from the eaves will collide with the rainwater diffuser after entering between the rising portions, It is possible to completely prevent the rainwater bounced by the rainwater diffuser from being diffused to the outer wall side of the building, which is particularly effective when there is a large amount of rainfall.
