[0001] The present invention relates to a splash prevention member and a rain gutter system.

Background Art

[0002] Generally, a building is provided with a rain gutter for receiving rainwater flowing down from the roof and draining it to the ground. The rain gutter is composed of a plurality of members such as eaves gutters, water collectors, downspouts, vertical gutters, connecting pipes, elbow joints, cheese joints (hereinafter, each joint is simply referred to as an elbow or a cheese), etc. In recent years, in order to improve the drainage capacity of the rain gutter, a siphon rain gutter system has been proposed in which the inside of the vertical gutter is filled with water to generate a water suction effect (so-called siphon phenomenon) and the drainage volume is increased dramatically (see Patent Document 1). <00,00010>

[0003] Depending on the building, in addition to the roof located at the top of the building, there may be a shelter roof above the entrance and windows. At this time, in addition to the roof located at the top, an eaves gutter may also be provided on the shelter roof. In addition, a vertical gutter for draining the rainwater collected in the eaves gutter to the ground is provided in the eaves gutter provided on the roof located at the top of the building. At this time, a shelter roof part and an eaves gutter may be provided directly below the vertical gutter.

[0004] In this case, the vertical gutter may penetrate the eaves gutter of the shelter roof part and the rainwater may flow down to the ground as it is. However, the eaves gutter of the shelter roof may be thinner than the vertical gutter and may not be able to penetrate the eaves gutter. For this reason, the outlet of the vertical gutter may be provided above the eaves gutter of the shelter roof part, and the rainwater from the vertical gutter may be drained into the eaves gutter of the shelter roof part.

Summary of the Invention

[0006] However, when the amount of rainwater flowing down the downpipe increases, the water flows forcefully into the eaves gutter of the canopy roof. This causes rainwater to splash from the eaves gutter, resulting in soiling of the eaves. As a conventional solution, an elbow was installed at the outlet of the downpipe to change the flow of rainwater so that it was parallel to the eaves gutter of the canopy roof. However, during heavy rain, rainwater would still splash out of the eaves gutter, so this was not an adequate solution.

[0007] As a further measure against the above, there was a proposal to place multiple tee joints on the eaves gutter of the canopy roof. In other words, the idea was to increase the number of water discharge points from the downpipe on the eaves gutter of the canopy roof, thereby distributing the amount of rainwater discharged to one location. However, this presented difficulties in terms of cost and workability due to the large number of components required.

[0008] This invention has been made in view of the circumstances described above, and it can prevent eaves and the like from getting dirty, reduce construction costs, and further improve work efficiency. Rain gutter systems, buildings The purpose is to provide. [Means for solving the problem]

[0009] To solve the aforementioned problems, the present invention proposes the following means. The scattering prevention member according to the present invention has a U-shaped main body and a connecting portion provided at the U-shaped bottom of the main body, and is installed with the connecting portion facing upwards, and the outlet of a downpipe is connected to the connecting portion.

[0010] According to this invention, the main body is provided with the connection part facing upwards, and the outlet of the downpipe is connected to the connection part. That is, first, the wastewater discharged from the outlet of the downpipe flows into the main body through the connection part. Immediately after that, the wastewater collides with the floor portion of the gutter on which the main body is provided. In this configuration, the main body is positioned with its U-shaped bottom facing upwards relative to the floor portion of the gutter. That is, the main body is positioned to cover the area around the point where the drainage impacts the floor portion of the gutter. Therefore, the splash prevention member alone can prevent the drainage that impacts the floor portion of the gutter from splashing into the surrounding area. This prevents the eaves and other areas from becoming soiled. Furthermore, the U-shape of the scattering prevention component is simple, making it easy to manufacture and install. This means that the cost of parts and construction costs can be reduced. In addition, work efficiency can be improved.

[0011] Alternatively, the rain gutter system may include the aforementioned splash-proof member, a first gutter, a second gutter, and the aforementioned downpipe, wherein the downpipe allows rainwater collected in the first gutter to flow down to the second gutter, the splash-proof member is provided on the floor of the second gutter, and the outlet of the downpipe is connected to the connection part of the splash-proof member.

[0012] According to this invention, the downpipe allows rainwater collected in the first gutter to flow down into the second gutter, the splash prevention member is provided on the floor of the second gutter, and the outlet of the downpipe is connected to the connection part of the splash prevention member. This allows rainwater collected in the first gutter to flow down into the second gutter. Furthermore, the splash prevention member alone can prevent the rainwater that flows down into the second gutter from splashing into the surrounding area. [Effects of the Invention]

[0013] According to the present invention, it is possible to provide a scattering prevention member that prevents soiling of eaves and the like, reduces construction costs, and further improves work efficiency. [Brief explanation of the drawing]

[Figure 2] Figure 1 is a front view showing the entire rain gutter system. [Figure 3] This is a perspective view showing the anti-scattering member according to the present invention installed in a gutter. [Figure 4] It is a cross-sectional view in the IV-IV direction of the splash prevention member shown in FIG. 3. [Figure 5] It is a perspective view showing a case where the splash prevention member according to the present invention is not installed.

Mode for Carrying Out the Invention

[0015] Hereinafter, referring to the drawings, a splash prevention member according to an embodiment of the present invention will be described. As shown in FIGS. 1 and 2, a rain gutter system 100 installed in a building 1 includes a first eaves gutter 10, a drainage member 20, a first vertical gutter 30, a second eaves gutter 40, a splash prevention member 50, a second vertical gutter 60, and a third vertical gutter 70. Rainwater flowing into the first eaves gutter 10 flows down to the first vertical gutter 30 or the second vertical gutter 60 through the drainage member 20. The rainwater flowing down to the first vertical gutter 30 is discharged to the second eaves gutter 40. The rainwater flowing down to the second eaves gutter 40 is drained to a drainage facility (not shown) through the third vertical gutter 70. Also, the rainwater flowing down to the second vertical gutter 60 is directly drained to a drainage facility (not shown).

[0016] The first eaves gutter 10 collects rainwater falling on the large roof 2 of the building 1. The rainwater collected by the first eaves gutter 10 flows down to the first vertical gutter 30 through the drainage member 20. The drainage member 20 is attached between the first eaves gutter 10 and the first vertical gutter 30, between the first eaves gutter 10 and the second vertical gutter 60 (not shown), and between the second eaves gutter 40 and the third vertical gutter 70 (not shown). When a large amount of rainwater is collected in the first eaves gutter 10 and the second eaves gutter 40, the drainage member 20 causes a siphon phenomenon in the pipes below the first vertical gutter 30, the second vertical gutter 60, and the third vertical gutter 70. As a result, the pipes below the first vertical gutter 30, the second vertical gutter 60, and the third vertical gutter 70 are filled with rainwater. This serves to improve the drainage efficiency.

[0017] The first vertical gutter 30 conveys the rainwater flowing down from the first eaves gutter 10 towards the second eaves gutter 40. The first vertical gutter 30 is provided vertically to the building 1. The upstream end of the first vertical gutter 30 is connected to the first eaves gutter 10. In the present embodiment, the nominal diameters of the first vertical gutter 30 of nominal diameters 80, 100, and 125 defined in JIS K 6741 (2007) are preferably used.

[0018] The second eaves gutter 40 collects the rainwater falling on the eaves roof 3 of the building 1. Also, it collects the rainwater discharged from the first vertical gutter 30. The rainwater flowing down to the second eaves gutter 40 flows down to the third vertical gutter 70 via the drainage member 20.

[0019] The second vertical gutter 60 conveys the rainwater flowing down from the first eaves gutter 10 towards a drainage facility not shown. The second vertical gutter 60 is provided vertically to the building 1. The upstream end of the second vertical gutter 60 is connected to the first eaves gutter 10. In the present embodiment, the nominal diameters of the second vertical gutter 60 of nominal diameters 80, 100, and 125 defined in JIS K 6L41 (2007) are preferably used.

[0020] The third vertical gutter 70 conveys the rainwater flowing down from the second eaves gutter 40 towards a drainage facility not shown. The third vertical gutter 70 is provided vertically to the building 1. The upstream end of the third vertical gutter 70 is connected to the second eaves gutter 40. In the present embodiment, the nominal diameters of the third vertical gutter 70 of nominal diameters 150, 200, 250, etc., corresponding to the total of the outflow water volume from the first vertical gutter 30 and the rainfall amount on the eaves roof 3, are preferably used.

[0021] The splash prevention member 50 prevents the rainwater discharged from the first vertical gutter 30 to the second eaves gutter 40 from splashing around. The splash prevention member 50 has a U-shaped main body portion 51 and a connection portion 52 provided at the U-shaped bottom portion 51a of the main body portion 51. The main body 51 has a U-shape in the front view shown in Figure 2 (a front view of the main body 51 viewed from the longitudinal direction of the second gutter 40). In the front view, the main body 51 is symmetrical in the short direction of the second gutter 40. The main body 51 has a bottom portion 51a and a side portion 51b.

[0022] In this embodiment, the bottom portion 51a is a rectangular flat plate. The bottom portion 51a is positioned opposite the floor surface of the second gutter 40. The bottom portion 51a is positioned parallel to the floor surface of the second gutter 40. The central part of the rectangular bottom portion 51a has a connecting portion 52, which will be described later. In addition, side portions 51b are provided at both ends of the bottom portion 51a in the front view shown in Figure 2 (both ends in the short direction of the second gutter 40). In this embodiment, the side portion 51b is a rectangular flat plate. One end of the side portion 51b is connected to both ends of the bottom portion 51a in the front view shown in Figure 2. The side portion 51b is also provided parallel to the depth direction of the second gutter 40. As a result, the main body portion 51 has a U-shape. The other end of the side portion 51b is in contact with the floor portion of the second gutter 40. Furthermore, the size of the side portion 51b in the depth direction (plate width) is shorter than the size of the main body portion 51 in the short-side direction (plate width) of the second gutter 40.

[0023] Specifically, as shown in Figure 3, the scattering prevention member 50 is provided on the floor portion of the second gutter 40 with the connecting portion 52 facing upwards. The main body portion 51 is integrally molded, and the connecting portion between the bottom portion 51a and the side portion 51b has a curved shape. The connecting portion 52 is provided in the central part of the rectangular bottom portion 51a. The connecting portion 52 has a cylindrical shape extending outward from the U-shape of the main body portion 51 through the through hole provided in the bottom portion 51a. As shown in Figure 4, the downstream end of the first downpipe 30, i.e., the drain outlet, is connected to the connection part 52. The first downpipe 30 is inserted into the connection part 52 as appropriate so as not to come into contact with the floor portion of the second gutter 40, with an insertion length of, for example, 40 to 80 mm.

[0024] The length of the second gutter 40 of the scattering prevention member 50 is preferably about 1.5 to 5.0 times the nominal diameter of the first downpipe 30. The dimension (width) of the scattering prevention member 50 in the short-side direction of the second gutter 40 is preferably larger than the nominal diameter of the first downpipe 30 and smaller than the inner width of the second gutter 40 to be installed. The depth dimension (height) of the second gutter 40 of the scattering prevention member 50 is preferably such that the cross-sectional area in the short direction of the second gutter 40 in the portion enclosed by the bottom 51a of the main body 51, the two side portions 51b, and the bottom surface of the second gutter 40 is larger than the opening area of ​​the first downpipe 30, and is at least lower than the height dimension of the second gutter 40.

[0025] The material of the shatterproof member 50 is preferably a synthetic resin such as rigid polyvinyl chloride resin, polycarbonate, ABS, or AES. Furthermore, injection molding is preferably used as the molding method for the shatterproof member 50.

[0026] The method for attaching the anti-scattering member 50 to the second gutter 40 is preferably adhesive. An epoxy adhesive is preferably used for this attachment. Furthermore, the connection between the scattering prevention member 50 and the first downpipe 30 is made by inserting the downstream end of the first downpipe 30 into the connection part 52. Note that the first downpipe 30 may expand or contract depending on the temperature of the installation location. To absorb this deformation, the first downpipe 30 and the connection part 52 may be connected by insertion only, without fixing them with adhesive or the like.

[0027] Next, the flow of rainwater that flows into the anti-scattering member 50 will be explained using Figures 4 and 5. As shown in Figures 4 and 5, rainwater flowing down from the first downpipe 30 is discharged into the second gutter 40. At this time, the rainwater falls through the first downpipe 30 due to gravity. As a result, the fallen rainwater collides with the floor of the second gutter 40 while still retaining its kinetic energy. Therefore, the rainwater moves in a way that it reflects off the floor of the second gutter 40.

[0028] In this case, if the distance rainwater travels within the first downpipe 30 is short, or if only a small amount of rainwater falls, the kinetic energy of the rainwater will be small. Therefore, the rainwater reflected from the floor of the second gutter 40 will remain inside the second gutter 40. In other words, the fallen rainwater will not scatter outside the second gutter 40.

[0029] However, if the distance rainwater falls within the first downpipe 30 is long, or if a large amount of rainwater flows rapidly through the first downpipe 30 due to the siphon effect, the kinetic energy of the rainwater will increase. In this case, as shown in Figure 5, if the splash prevention member 50 is not provided, rainwater reflected from the floor portion of the second gutter 40 will not remain inside the second gutter 40 but will be scattered to the outside.

[0030] As shown in Figure 4, when a splash prevention member 50 is installed at the outlet of the first downpipe 30, splashed rainwater collides with the U-shaped inner surface of the main body 51 of the splash prevention member 50. Furthermore, both ends of the U-shape of the splash prevention member 50 are in contact with the floor of the second gutter 40. In other words, the splash prevention member 50 is installed so as to cover the area around the point where rainwater collides with the floor of the second gutter 40. As a result, rainwater that collides with the inner surface of the main body 51 remains inside the splash prevention member 50. This prevents the falling rainwater from splashing outside the second gutter 40.

[0031] As described above, according to the scattering prevention member 50 of this embodiment, the main body 51 is provided with the connecting portion 52 facing upwards, and the outlet of the first downpipe 30 is connected to the connecting portion 52. That is, first, the wastewater discharged from the outlet of the first downpipe 30 flows into the main body 51 through the connecting portion 52. Immediately after that, the wastewater collides with the floor portion of the second gutter 40 on which the main body 51 is provided. At this time, the main body 51 is provided with its U-shaped bottom facing upwards relative to the floor portion of the second gutter 40. In other words, the main body 51 is provided so as to cover the area around the point where the drainage hits the floor portion of the second gutter 40. Therefore, the splash prevention member 50 alone can prevent the drainage that hits the floor portion of the second gutter 40 from splashing into the surrounding area. Thus, it is possible to prevent the eaves and other areas from becoming soiled. Furthermore, the U-shape of the scattering prevention member 50 is simple, making it easy to manufacture and install. In other words, the cost of parts and construction costs can be reduced. Moreover, work efficiency can be improved.

[0032] Furthermore, the first downpipe 30 directs rainwater collected in the first gutter 10 down to the second gutter 40, the splash prevention member 50 is installed on the floor of the second gutter 40, and the outlet of the first downpipe 30 is connected to the connection part 52 of the splash prevention member 50. This allows rainwater collected in the first gutter 10 to flow down to the second gutter 40. Moreover, the splash prevention member 50 alone can prevent the rainwater that flows down to the second gutter 40 from splashing into the surrounding area.

[0033] It should be noted that the technical scope of the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention. For example, multiple first downpipes 30 may be provided in relation to the second eaves gutter 40. Furthermore, the second downpipe 60 may be provided only once, or it may not be provided at all. Furthermore, multiple third downpipes 70 may be provided in relation to the second eaves gutter 40. Furthermore, the specific shape of the scattering prevention member 50 does not have to be U-shaped. For example, it may be a flat plate shape having only the bottom portion 51a in this embodiment.

[0034] Furthermore, the anti-scattering member 50 and the first downpipe 30 may be fixed together by means of a fitting or other method. In that case, the deformation allowance of the first downpipe 30 may be absorbed by not fixing the anti-scattering member 50 and the second downpipe 40. In other words, the anti-scattering member 50 and the floor portion of the second downpipe 40 do not need to be in contact. Furthermore, the anti-scattering member 50 and the second gutter 40 may be attached by a fitting or other method. Alternatively, the anti-scattering member 50 and the second gutter 40 do not need to be fixed together by adhesive or other means. In other words, the anti-scattering member 50 may simply be placed on the second gutter 40. Furthermore, the cylindrical shape of the connecting portion 52 in the scattering prevention member 50 may be located inside the U-shaped shape of the main body portion 51. Alternatively, the connecting portion 52 does not have to be cylindrical. That is, the connecting portion 52 may be formed simply by providing a through hole in the bottom portion 51a of the main body portion 51.

[0035] Furthermore, without departing from the spirit of the present invention, the components in the above embodiments may be replaced with well-known components as appropriate, and the above-described modifications may be combined as appropriate. [Explanation of symbols]
