Description

Technical Field

[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 flowing it onto the ground. The rain gutter is composed of a plurality of combinations 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 cheese), etc. In recent years, in order to increase 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 action (so-called siphon phenomenon) and the drainage volume is increased dramatically (see Patent Document 1).

[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 flowing down the rainwater collected in the eaves gutter onto 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

Problems to be Solved by the Invention

[0006] However, when the amount of rainwater flowing down the vertical gutter increases, the water flows vigorously down the eaves gutter at the eaves root of the gable roof. Then, there is a problem that rainwater scatters from the eaves gutter at the eaves root of the gable roof and the eaves tip gets dirty. In response to this, as a conventional measure, an elbow was provided at the outlet of the vertical gutter, and the flow of rainwater was changed so as to be parallel to the eaves gutter at the eaves root of the gable roof for drainage. However, during heavy rain, rainwater splashes out from the eaves gutter, which was not a sufficient measure.

[0007] As a further measure against the above, there was a proposal to arrange a plurality of cheese joints on the eaves gutter of the gable roof. That is, there was a proposal to increase the number of drainage parts from the vertical gutter on the eaves gutter of the gable roof to a plurality, and to disperse the amount of rainwater drained to one place. However, because a large number of members were used, there were difficulties in terms of cost and workability.

[0008] The present invention has been made in view of the above circumstances, and an object thereof is to provide a scattering prevention member that can prevent the eaves tip and the like from getting dirty, reduce construction costs, and further improve workability.

Means for Solving the Problems

[0009] In order to solve the above problems, the present invention proposes the following means. The scattering prevention member according to the present invention has a U-shaped main body portion and a connecting portion provided at the U-shaped bottom portion of the main body portion, and is provided with the connecting portion on the upper side, and the outlet of the vertical gutter is connected to the connecting portion.

[0010] According to this invention, the main body portion is provided with the connecting portion on the upper side, and the outlet of the vertical gutter is connected to the connecting portion. That is, first, the drainage discharged from the outlet of the vertical gutter flows into the main body portion through the connecting portion. Immediately after that, the drainage collides with the floor portion of the eaves gutter where the main body portion is provided. At this time, the main body is provided with the U-shaped bottom facing upward with respect to the floor of the eaves gutter. That is, the main body is provided so as to cover the periphery of the drainage collision part on the floor of the eaves gutter. Therefore, it is possible to prevent the drainage that has collided with the floor of the eaves gutter from splashing around only by the splash prevention member. Thus, it is possible to prevent the eaves tip and the like from being soiled. In addition, the U-shaped shape of the splash prevention member is simple, and manufacturing and installation are easy. That is, the cost of parts and the construction cost can be reduced. Furthermore, workability can be improved.

[0011] Further, it may be a rain gutter system including the splash prevention member, the first eaves gutter, the second eaves gutter, and the vertical gutter. The vertical gutter causes the rainwater concentrated in the first eaves gutter to flow down to the second eaves gutter. The splash prevention member is provided on the floor of the second eaves gutter, and the outlet of the vertical gutter is connected to the connection part of the splash prevention member.

[0012] According to this invention, the vertical gutter causes the rainwater concentrated in the first eaves gutter to flow down to the second eaves gutter. The splash prevention member is provided on the floor of the second eaves gutter, and the outlet of the vertical gutter is connected to the connection part of the splash prevention member. Thereby, the rainwater concentrated in the first eaves gutter can be made to flow down to the second eaves gutter. Furthermore, it is possible to prevent the rainwater flowing down to the second eaves gutter from splashing around only by the splash prevention member.

Effects of the Invention

[0013] According to the present invention, it is possible to provide a splash prevention member that can prevent the eaves tip and the like from being soiled, reduce the construction cost, and further improve workability.

Mode for Carrying Out the Invention

[0015] Hereinafter, with reference 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. The 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 the rainwater that has fallen 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 generates 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 toward 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 are preferably those of nominal diameters 80, 100, and 125 defined in JIS K 6741 (2007).

[0018] The second eaves gutter 40 collects the rainwater that has fallen 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 toward 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 are preferably those of nominal diameters 80, 100, and 125 defined in JIS K 6741 (2007).

[0020] The third vertical gutter 70 conveys the rainwater flowing down from the second eaves gutter 40 toward 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 are preferably those that match the total of the outflow water volume from the first vertical gutter 30 and the rainfall amount on the eaves roof 3, such as nominal diameters 150, 200, and 250 defined in JIS K 6741 (2007).

[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 connecting portion 52 provided at the U-shaped bottom portion 51a of the main body portion 51. The main body portion 51 has a U-shaped configuration in the front view shown in FIG. 2 (front view of the main body portion 51 seen from the longitudinal direction of the second eaves gutter 40). The main body portion 51 is symmetric with respect to the short direction of the second eaves gutter 40 in the front view. The main body portion 51 has a bottom portion 51a and side surface portions 51b.

[0022] In the present embodiment, the bottom portion 51a is a flat plate having a rectangular shape. The bottom portion 51a is positioned facing the floor surface of the second eaves gutter 40. The bottom portion 51a is positioned parallel to the floor surface of the second eaves gutter 40. A connection portion 52 described later is provided at the central portion of the rectangular shape of the bottom portion 51a. Further, side surface portions 51b are provided at both end portions (both end portions in the short direction of the second eaves gutter 40) of the bottom portion 51a in the front view shown in FIG. 2. In the present embodiment, the side surface portion 51b is a flat plate having a rectangular shape. One end portion of the side surface portion 51b is connected to both end portions of the bottom portion 51a in the front view shown in FIG. 2. Further, the side surface portion 51b is provided parallel to the depth direction of the second eaves gutter 40. Thereby, the main body portion 51 has a U-shaped configuration. Note that the other end portion of the side surface portion 51b is in contact with the floor portion of the second eaves gutter 40. Further, the size (plate width) in the depth direction of the side surface portion 51b is shorter than the size (plate width) in the short direction of the second eaves gutter 40 in the main body portion 51.

[0023] That is, as shown in FIG. 3, the splash prevention member 50 is provided on the floor portion of the second eaves gutter 40 with the connection portion 52 on the upper side. Further, the main body portion 51 is integrally formed, and the connecting portion between the bottom portion 51a and the side surface portion 51b has a curved surface shape. The connection portion 52 is provided at the central portion of the rectangular shape of the bottom portion 51a. The connection portion 52 has a cylindrical shape extending outward from the through hole provided in the bottom portion 51a toward the outside of the U-shaped configuration of the main body portion 51. As shown in FIG. 4, the downstream end of the first vertical gutter 30, that is, the drainage outlet, is connected to the connection portion 52. The first vertical gutter 30 is appropriately inserted into the connection portion 52 so as not to contact the floor portion of the second eaves gutter 40, and the insertion length is, for example, 40 to 80 mm.

[0024] The longitudinal dimension (length) of the second eaves gutter 40 of the splash prevention member 50 is preferably about 1.5 to 5.0 times the nominal diameter of the first downspout 30. The transverse dimension (width) of the second eaves gutter 40 of the splash prevention member 50 is preferably larger than the nominal diameter of the first downspout 30 and smaller than the inner width of the second eaves gutter 40 where it is installed. The depth dimension (height) of the second eaves gutter 40 of the splash prevention member 50 is preferably such that the cross-sectional area in the transverse direction of the second eaves gutter 40 in the portion surrounded by the bottom 51a of the main body 51, the two side faces 51b, and the bottom surface of the second eaves gutter 40 is larger than the opening area of the first downspout 30, and is at least lower than the height dimension of the second eaves gutter 40.

[0025] As the material of the splash prevention member 50, synthetic resins such as rigid vinyl chloride resin, polycarbonate, ABS, and AES are preferably used. Also, as the molding method of the splash prevention member 50, injection molding is preferably used.

[0026] As the attachment method of the splash prevention member 50 to the second eaves gutter 40, adhesion is preferably used. For adhesion, epoxy-based adhesives are preferably used. Also, the connection between the splash prevention member 50 and the first downspout 30 is made by inserting the downstream end of the first downspout 30 into the connection part 52. Note that the first downspout 30 may expand or contract depending on the air temperature at the installation location, etc. In order to absorb the deformation allowance, the first downspout 30 and the connection part 52 may be connected only by insertion without fixing by adhesion or the like.

[0027] Next, the flow of rainwater flowing down into the splash prevention member 50 will be described with reference to FIGS. 4 and 5. As shown in FIGS. 4 and 5, the rainwater flowing down from the first downspout 30 is discharged into the second eaves gutter 40. At this time, the rainwater falls in the first downspout 30 by gravity. Therefore, the fallen rainwater collides with the floor of the second eaves gutter 40 while having kinetic energy. Thus, the rainwater moves so as to be reflected from the floor of the second eaves gutter 40.

[0028] At this time, when the falling distance of rainwater in the first vertical downspout 30 is short, or when the amount of fallen rainwater is small, the kinetic energy of the rainwater becomes small. Therefore, the rainwater reflected from the floor of the second eaves gutter 40 stays inside the second eaves gutter 40. That is, the fallen rainwater does not scatter outside the second eaves gutter 40.

[0029] However, when the falling distance of rainwater in the first vertical downspout 30 is long, or when a large amount of rainwater flows rapidly through the first vertical downspout 30 due to the siphon phenomenon, the kinetic energy of the rainwater becomes large. At this time, as shown in FIG. 5, when the splash prevention member 50 is not provided, the rainwater reflected from the floor of the second eaves gutter 40 scatters outside instead of staying inside the second eaves gutter 40.

[0030] As shown in FIG. 4, when the splash prevention member 50 is provided at the outlet of the first vertical downspout 30, the scattered rainwater collides with the inside of the U-shaped body portion 51 of the splash prevention member 50. Also, both ends of the U-shaped splash prevention member 50 are in contact with the floor of the second eaves gutter 40. That is, the splash prevention member 50 is provided so as to cover the periphery of the collision portion of the rainwater on the floor of the second eaves gutter 40. For this reason, the rainwater that has collided with the inside of the body portion 51 stays inside the splash prevention member 50. This prevents the fallen rainwater from scattering outside the second eaves gutter 40.

[0031] As described above, according to the splash prevention member 50 according to the present embodiment, the body portion 51 is provided with the connecting portion 52 on the upper side, and the outlet of the first vertical downspout 30 is connected to the connecting portion 52. That is, first, the drainage discharged from the outlet of the first vertical downspout 30 flows into the body portion 51 through the connecting portion 52. Immediately after that, the drainage collides with the floor of the second eaves gutter 40 where the body portion 51 is provided. At this time, with respect to the floor portion of the second eaves gutter 40, the main body portion 51 is provided with the U-shaped bottom facing upward. That is, the main body portion 51 is provided so as to cover the periphery of the drainage collision portion on the floor portion of the second eaves gutter 40. Therefore, only by the splash prevention member 50, it is possible to prevent the drainage that has collided with the floor portion of the second eaves gutter 40 from splashing around. Thus, it is possible to prevent the eaves tip and the like from being soiled. In addition, the U-shaped shape of the splash prevention member 50 is simple, and manufacturing and installation are easy. That is, the cost of parts and the construction cost can be reduced. Furthermore, workability can be improved.

[0032] Also, the first vertical gutter 30 causes the rainwater collected in the first eaves gutter 10 to flow down to the second eaves gutter 40. The splash prevention member 50 is provided on the floor portion of the second eaves gutter 40, and the outlet of the first vertical gutter 30 is connected to the connection portion 52 of the splash prevention member 50. Thereby, the rainwater collected in the first eaves gutter 10 can be made to flow down to the second eaves gutter 40. Furthermore, the splash prevention member 50 alone can prevent the rainwater that has flowed down to the second eaves gutter 40 from splashing around.

[0033] Note that the technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, a plurality of the first vertical gutters 30 may be provided with respect to the second eaves gutter 40. Also, only one second vertical gutter 60 may be provided, or it may not be provided. Also, a plurality of the third vertical gutters 70 may be provided with respect to the second eaves gutter 40. Also, the specific shape of the splash 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 the present embodiment.

[0034] Also, the splash prevention member 50 and the first vertical gutter 30 may be fixed by a method such as fitting. In that case, by not fixing the splash prevention member 50 and the second eaves gutter 40, the deformation allowance of the first vertical gutter 30 may be absorbed. That is, the splash prevention member 50 and the floor portion of the second eaves gutter 40 do not have to be in contact. Further, the splash prevention member 50 and the second eaves gutter 40 may be attached by a method such as fitting. Alternatively, the splash prevention member 50 and the second eaves gutter 40 do not have to be fixed, such as by adhesion. That is, the splash prevention member 50 may simply be disposed on the second eaves gutter 40. Also, the cylindrical shape of the connection portion 52 in the splash prevention member 50 may be located inside the U-shaped shape of the main body portion 51. Alternatively, the connection portion 52 does not have to be cylindrical. That is, the connection portion 52 may be formed only by providing a through hole in the bottom portion 51a of the main body portion 51.

[0035] In addition, within the scope not departing from the gist of the present invention, it is possible to appropriately replace the constituent elements in the above-described embodiment with well-known constituent elements, and the above-described modification examples may also be appropriately combined.
