Description

The present invention has a substantially cylindrical rising portion having an inspection port on the upper part and an outlet on the peripheral wall, a mounting portion attached to the outlet so as to project into the rising portion, and a mounting portion. On the other hand, the rainwater control unit is equipped with a rainwater control unit such as a filter that can be attached and detached, and rainwater or rainwater permeates (hereinafter collectively referred to as "rainwater"). The center of the upper end of the handle of the rainwater control unit is deviated from the normal line passing through the center of the handle of the rainwater control unit in a plane parallel to the rotation surface of the mounting port. Regarding the rainwater that is placed in mind.

Generally, rainwater that falls on the roof of a building is collected by rainwater in a residential area. Foreign substances such as mud and dead leaves may be mixed in the rainwater. Therefore, in order to prevent foreign matter such as mud from flowing out to the outside of the rainwater basin, for example, as described in Japanese Patent Application Laid-Open No. 2017-150191 (Patent Document 1), foreign matter is trapped in the lower part of the main body. It is known that a mud reservoir equipped with a mud reservoir (bucket) is provided, and a filter, an orifice, a check valve, etc. are provided inside the peripheral wall of the main body to prevent the outflow of foreign matter. ing.

In a rainwater basin as described in Patent Document 1, the filter etc. is integrally attached to the handle frame of the bucket so that the bucket does not interfere with the filter etc. protruding into the inside of the main body when the bucket is taken in and out. The handle frame of the bucket is structured so that it can be attached and detached so as to be in close contact with the inner wall by inserting and removing it into the slide groove provided on the inner wall of the main body.

However, the structure described in Patent Document 1 in which a filter or the like is integrally attached to the handle frame of the bucket is extremely complicated and has no versatility, so that there is a problem that the manufacturing cost becomes extremely high.

Further, as a mechanism for allowing a device such as a water-sealing elbow or a filter to be detachably attached to the inside of a drainage basin by a simple structure, for example, Japanese Patent Application Laid-Open No. 2011-220012 (Patent Document 2) is described. A detachable mechanism using a bayonet method is known.

However, the attachment / detachment mechanism described in Patent Document 2 is attached to the water sealing elbow or the like in order to secure the rotation angle required for attaching and removing the water sealing elbow or the filter to the joint means in the bayonet method. There was a restriction that the length of the handle to be drained could not be substantially longer than the radius of the body so that it would not interfere with the inner wall of the body. Therefore, when the attachment / detachment mechanism described in Patent Document 2 is used, when the attachment position of the filter or the like is deeper downward from the inspection port of the main body, the water sealing elbow or the like should be attached to and removed from the joint means. There was a problem that it could not be done.

Japanese Unexamined Patent Publication No. 2017-150191 Japanese Unexamined Patent Publication No. 2011-220012

Therefore, according to the present invention, in a rainwater basin having a rising portion having an inspection port at the upper part and an outlet at which a rainwater control unit such as a filter can be attached to the peripheral wall, the rainwater control unit moves downward from the inspection port of the main body. Whether installed in a deep position or at any height in the body, the relatively simple structure allows the stormwater control unit to be attached to the outlet to provide a removable stormwater basin. The purpose is.

The present inventors have made a stormwater control unit having a rising portion having an inspection port and an outlet to which a rainwater control unit such as a filter can be attached, regardless of the mounting position of the rainwater control unit in the main body. In order to make it removable by attaching it to the outlet, we have been diligently studying the mechanism for attaching and detaching the rainwater control unit to the outlet and the means for attaching and detaching the rainwater control unit. As a result, the rainwater control unit is attached to and detached from the outlet by a bayonet method, and the center of the upper end of the handle of the rainwater control unit is attached to the handle of the rainwater control unit in a plane parallel to the rotation surface of the outlet. We have found that the above-mentioned problems can be solved by eccentrically arranging them from the normal line passing through the center of the portion, and have completed the present invention.

That is, according to the present invention, the main body is provided with a substantially cylindrical rising portion having an inspection port at the upper part and an outlet at the peripheral wall, and a mounting port is provided at the end portion so as to project into the rising portion. A rainwater control unit consisting of a mounting unit that is attached to the outlet, a control unit body that has a mounting unit that is detachably attached to the mounting port by a bayonet method, and a rod-shaped handle that extends upward from the control unit body. And the center of the upper end of the handle is placed eccentrically from the normal passing through the center of the handle mounting part on the control unit body in a plane parallel to the rotating surface of the mounted part. Will be provided.

In addition, the rainwater basin of the present invention is provided with a substantially cylindrical bottomed mud reservoir at the bottom of the rising portion of the main body, and a bucket is detachably housed in the mud reservoir, and the inner diameter of the rising portion is increased. Can be made larger than the outer diameter of the bucket, and the central axis of the rising portion can be eccentric to the outlet side of the central axis of the mud reservoir.

Here, the "substantially cylindrical shape" is not only a cylindrical shape having the same diameter over the entire length, but also a cylindrical shape including a different diameter portion over the entire length such as a cone or a gourd shape, and a flange is provided on the outer peripheral portion. It is a concept that includes a cylindrical shape, a cylindrical shape with slits, holes, and openings in the peripheral wall.

In the rainwater basin of the present invention, in order to control the flow of rainwater, an end portion for attaching a rainwater control unit such as a filter, an orifice, and a check valve to an outlet provided at a substantially cylindrical rising portion. A mounting portion having a mounting port is mounted so as to project into the rising portion. Then, a rainwater control unit consisting of a control unit main body having a mounted portion and a rod-shaped handle is detachably attached to the mounting port of the mounting portion by using a bayonet method, but upward from the control unit main body. The center of the upper end portion of the extending handle is characterized in that it is arranged eccentrically from the normal line passing through the center of the handle mounting portion on the control unit main body in a plane parallel to the rotating surface of the mounted portion. Further, the handle does not have to be entirely rod-shaped, and in particular, a part of the upper portion that may come into contact with the inner wall of the rising portion may be rod-shaped.

Here, the "bayonet method" means that the bayonet protrusion provided on the mounted portion on the rainwater control unit side is rotated in the circumferential direction to the bayonet groove provided on the mounting port on the mounting portion side. It is a mechanism to fit. When the bayonet method is used for the attachment / detachment mechanism of the rainwater control unit, the rainwater control unit can be easily and surely attached / detached to / from the attachment portion with a relatively small rotation angle.

In the case of the rainwater basin of the present invention, the center of the upper end portion of the handle attached to the control unit main body is arranged eccentrically from the normal line passing through the center of the handle attachment portion on the control unit main body, so that the upper end portion of the handle is arranged. Is such that the distance from the upper end of one side to the inner wall of the rising portion is longer than the distance from the upper end of the other side to the inner wall of the rising portion in a plane parallel to the rotating surface of the mounted portion. Is placed in.

Therefore, in the rainwater basin of the present invention, the center of the upper end portion of the handle is eccentric from the normal line passing through the center of the attachment portion of the handle in the rotation direction for mounting the control unit main body to the attachment portion. For example, it can be arranged in a plane parallel to the rotating surface of the mounted portion.

More specifically, for example, when the handle of the rainwater control unit is in a state of being upright in a substantially vertical direction in a plane parallel to the rotating surface of the mounted portion, the mounting position where the rainwater control unit is engaged with the mounting portion is used. On the other hand, the upper end of the handle of the rainwater control unit rotated to the side where the distance from the upper end to the inner wall of the rising portion was long in a plane parallel to the rotating surface of the mounted portion, and fell down. When in the state (tilted state), the rainwater control unit can be set to the detached position disengaged from the mounting unit. When the mounting position of the rainwater control unit is set when the handle is upright in the substantially vertical direction, it becomes easy to easily and accurately grasp the mounting state of the rainwater control unit both visually and tactilely.

In this case, the rotation stroke between the mounting position and the detaching position of the upper end of the handle and the rotation angle of the mounted portion are arranged on the normal line where the center of the upper end of the handle passes through the center of the mounting portion of the handle. It can be made longer and larger than the rotation stroke and the rotation angle in the case of. When the center of the upper end of the handle is not eccentric from the normal passing through the center of the attachment of the handle and is arranged on the normal, the upper end of the handle is in a plane parallel to the rotation plane of the mounted portion. Since the distance from the upper end of one side to the inner wall of the rising portion and the distance from the upper end of the other side to the inner wall of the rising portion are arranged to be equal, for example, in a plan view, the rotation stroke rises. This is because only half or less of the inner diameter of the part can be effectively used.

Further, in the rainwater basin of the present invention, for example, when the handle of the rainwater control unit is in a state of being upright in a substantially vertical direction in a plane parallel to the rotating surface of the mounted portion, the rainwater control unit is disengaged from the mounting portion. Set so that it is in the detachable position, while the upper end of the handle of the rainwater control unit rotates to the side with a longer distance from the upper end to the inner wall of the rising portion in a plane parallel to the rotating surface of the mounted portion. When it is in a fallen state (tilted state), the rainwater control unit may be set so as to be in the mounting position engaged with the mounting portion. If the detachment position of the rainwater control unit is when the handle is upright in the vertical direction, the filter can be raised and lowered while the handle is upright in the vertical direction to align it with the mounting port. Since it can be done, the operability of the filter is improved.

In this way, the rainwater basin of the present invention in which the center of the upper end of the handle is eccentric from the normal passing through the center of the mounting portion of the handle is on the normal line in which the center of the upper end of the handle passes through the center of the mounting portion of the handle. Compared to the arranged rainwater basin, the rotation stroke of the upper end of the handle and the rotation angle of the mounted portion can be made longer and larger. Therefore, for example, the present invention may be used in a rainwater basin in which the rainwater control unit is installed deeper downward from the inspection port of the main body, or in a rainwater basin installed at any height in the main body. If the handle used in is applied, the rotation angle required to attach and remove the rainwater control unit to the mounting part by the bayonet method, basically regardless of the height of the rising part, even from the upper inspection port of the rising part. Will be able to be secured.

In the rainwater basin of the present invention, examples of the rainwater control unit that is detachably attached to the attachment port of the attachment portion include a hemispherical filter made of a mesh, a conical orifice, and a check valve. , Not limited to these.

Further, the rainwater basin of the present invention is arranged so that the center of the upper end portion of the handle is eccentric from the normal line in a plane including a normal line passing through the center of the mounting portion of the handle and orthogonal to the rotation plane of the mounted portion. You can also do it.

In a plane that includes a normal that passes through the center of the mounting portion of the handle and is orthogonal to the surface of revolution of the mounted portion, for example, the center of the upper end of the handle is the center of the rising portion from the normal that passes through the center of the mounting portion of the handle. When arranged eccentrically in the axial direction, the closer to the central axis of the rising portion, the more from the inner wall of the rising portion on one side to the inner wall of the rising portion on the other side in the plane parallel to the rotating surface of the mounted portion. The distance is approximately equal to the inner diameter of the rising portion and is the longest.

Therefore, the center of the upper end portion of the handle is arranged eccentrically from the normal line passing through the center of the mounting portion of the handle in a plane parallel to the rotation surface of the mounted portion, and the normal line is included and mounted. If the portion is placed eccentrically from the normal even in a plane orthogonal to the rotating surface of the portion, the internal space (inner diameter) of the rising portion is fully utilized, and the mounting position and the detaching position of the upper end portion of the handle are set. The rotation stroke between them and the rotation angle of the mounted portion can be set.

In the rainwater basin of the present invention, when the rainwater control unit such as a filter is attached to the mounting portion, it is preferable that the handle portion of the rainwater control unit is arranged substantially parallel to the central axis of the rising portion of the rainwater basin. Since the handle part of the rainwater control unit is rod-shaped, if it is arranged substantially parallel to the central axis of the rising part, that is, if it is arranged substantially in the vertical direction, the rod-shaped part of the handle may extend or bend in the lateral direction. This reduces the risk of interference with the inner wall of the rising portion, and the internal space (inner diameter) of the rising portion can be effectively utilized.

The rainwater basin of the present invention may be connected to a substantially cylindrical bottomed mud reservoir provided with a detachably accommodating bucket at the lower part of the rising portion of the main body. In this case, the inner diameter of the rising portion may be connected. Is larger than the outer diameter of the bucket, and it is preferable that the central axis of the rising portion is eccentric to the outlet side of the central axis of the mud reservoir.

A stormwater basin with a mud reservoir has a mounting section and the end of the inflow branch or an external inflow tube connected to the inflow branch protruding inside the rise, and has a substantially cylindrical shape at the bottom. It is equipped with a mud reservoir at the bottom and a bucket that can be taken out and attached from inside the mud reservoir.

Therefore, in the rainwater basin of the present invention, the inner diameter of the substantially cylindrical rising portion is accommodated in the inner diameter of the substantially cylindrical mud reservoir connected to the lower portion thereof and the mud reservoir so that the bucket can be taken out. It is larger than the outer diameter of the substantially cylindrical bucket, and the central axis of the rising portion is eccentric to the outlet side of the central axis of the mud reservoir. Further, since the outer diameter of the bucket is smaller than the inner diameter of the mud reservoir, if the inner diameter of the rising portion is larger than the inner diameter of the mud reservoir, it is larger than the outer diameter of the bucket.

In the rainwater basin of the present invention, since the inner diameter of the rising portion is larger than the inner diameter of the mud reservoir, the inner wall surface of the mud reservoir is arranged in the inner region of the inner wall surface of the rising portion, and the central axis of the rising portion is mud. It can be arranged eccentrically with respect to the central axis of the reservoir.

Further, in the rainwater basin of the present invention, the central axis of the rising portion can be eccentric to the outlet side of the central axis of the mud reservoir, so that the bucket housed in the mud reservoir can be eccentric in a plan view. It can be arranged at a position where it does not overlap with the peripheral wall of the rising portion, the mounting portion attached to the rising portion, and the inflow branch pipe. In other words, in plan view, the outer diameter of the bucket housed in the mud reservoir is larger than the distance between the mounting port of the mounting portion in the rising portion and the end surface (inner wall surface) of the inflow port. small. Therefore, the rainwater basin of the present invention can be freely taken in and out of the mud reservoir by a simple structure without using a complicated filter attachment / detachment mechanism as described in Reference 1.

The main body of rainwater is mainly composed of a substantially cylindrical rising part and a substantially cylindrical bottomed mud reservoir, but both do not necessarily have to be integrally formed, and the rising part and the rising part. The mud reservoir may be formed as a separate and independent part.

If the rising portion and the mud reservoir portion are formed as separate parts, for example, since the rising portion has a substantially cylindrical shape, a general-purpose circular pipe can be easily diverted to the rising portion.

Further, even when the diameter of the rising portion and the diameter of the mud reservoir are different from each other, the inner diameter of the upper receiving portion is larger than the inner diameter of the lower receiving portion, and the central axis of the upper receiving portion is the central axis of the lower receiving portion. By sandwiching the different diameter cylinder joint eccentric from the above between the rising portion and the mud collecting portion, the rising portion and the mud collecting portion can be easily connected in any desired relative arrangement. Furthermore, the rainwater basin that connects the rising part and the mud reservoir using a different diameter cylinder joint has more freedom in design than the rainwater sewn that is integrally molded, and on the contrary, the manufacturing cost is greatly reduced. To.

According to the rainwater of the present invention, since the center of the upper end portion of the handle is eccentric from the normal line passing through the center of the handle mounting portion, the center of the upper end portion of the handle is on the normal line passing through the center of the handle mounting portion. Compared to the rainwater basin arranged in, the rotation stroke of the upper end of the handle and the rotation angle of the mounted portion can be made longer and larger. For this reason, for example, in a rainwater basin where a rainwater control unit such as a filter is installed deeper downward from the inspection port of the main body, or in a rainwater basin installed at any height in the main body. If the handle used in the present invention is applied, it is necessary to attach and remove the rainwater control unit to and from the mounting portion by the bayonet method, basically regardless of the height of the rising portion, even from the upper inspection port of the rising portion. It will be possible to secure a stable rotation angle.

Therefore, the center of the upper end portion of the handle is arranged eccentrically from the normal line passing through the center of the mounting portion of the handle in a plane parallel to the rotation surface of the mounted portion, and the normal line is included and mounted. If the portion is placed eccentrically from the normal even in a plane orthogonal to the rotating surface of the portion, the internal space (inner diameter) of the rising portion is fully utilized, and the mounting position and the detaching position of the upper end portion of the handle are set. It becomes possible to set the rotation stroke between them and the rotation angle of the mounted portion.

In the rainwater basin of the present invention, when a rainwater control unit such as a filter is attached to the mounting portion, the handle portion of the rainwater control unit is arranged so as to be substantially parallel to the central axis of the rising portion of the rainwater basin. The risk of interference with the inner wall of the rising portion is reduced by extending or bending in the lateral direction, and the internal space (inner diameter) of the rising portion can be effectively utilized.

According to the rainwater of the present invention, in a plan view, the bucket housed in the mud reservoir is placed at a position where it does not overlap with the peripheral wall of the rising portion, the mounting portion attached to the rising portion, and the inflow branch pipe. Since it can be arranged, the bucket can be freely taken in and out of the mud reservoir by a simple structure without using a complicated filter attachment / detachment mechanism or the like.

FIG. 7 shows a cross-sectional view of the rainwater basin 1 according to the present embodiment cut out in a BB cross section. Further, FIG. 9 shows a plan view of the rainwater basin 1 according to the present embodiment as viewed from above in the embodiment in which the filter 7 is removed from the mounting pipe 34 of the outlet 33.

As will be understood with reference to FIGS. A main body 2 consisting of a substantially cylindrical bottomed mud reservoir 4 connected to the lower part of the above, a bucket 5 detachably housed in the mud reservoir 4, a rising portion 3 and a mud reservoir 4 It is composed of a different diameter pipe joint 6 sandwiched between and. A filter 7 is attached to the outflow port 33 of the rising portion 3 via a mounting pipe 34 protruding inward, while the inflow port is an inflow side opening in the peripheral wall 31 of the rising portion using a hole saw or the like. It is formed by making a hole in 36 and attaching an inflow branch pipe 37 to the inflow side opening 36 (see FIGS. 4 and 8). Further, the above-mentioned parts constituting the rainwater basin 1 of the present embodiment are mainly made of vinyl chloride resin in consideration of its moldability, ease of handling and the like.

As shown in detail in FIGS. It has a mounting port 35.

10A, 10B and 10C show a front view, a rear view and a left side view of the filter 7 unit removed from the mounting pipe 34 of the outlet 33.

As shown in detail in FIGS. 10A, 10B, and 10C, the filter 7 detachably attached to the mounting tube 34 with respect to the mounting tube 34 has a hemispherical filter portion made of a mesh and the mounting tube 34. It is provided with a filter main body 71 including a mounting port 35 and a mounted portion 70 that engages and disengages by a bayonet method, and a rod-shaped handle 72 extending upward from the filter main body 71. The center 73 of the upper end portion of the handle 72 is arranged eccentrically from the normal line 74 passing through the center of the mounting portion of the handle 72 on the control unit main body 71 in a plane parallel to the rotating surface of the mounted portion 70. (See Figures 5, 10A and 10B). Further, the handle 72 does not have to be entirely rod-shaped, and in particular, a part of the upper portion that may come into contact with the inner wall of the rising portion 3 may be rod-shaped.

Here, the "bayonet method" is a mounting pipe 34 by rotating the filter main body (control unit main body) 71 in the circumferential direction of the bayonet protrusion provided on the mounted portion 70 on the filter (rainwater control unit) 7 side. It is a mechanism that fits into the bayonet groove provided in the mounting port 35 on the side. When the bayonet method is used for the attachment / detachment mechanism of the filter 7 or the like, the filter 7 or the like can be easily and surely attached to or detached from the mounting pipe 34 with a small rotation angle. Therefore, as in the present embodiment, the filter 7 has a rod-shaped handle 72. Is attached, the filter 7 can be easily attached and detached by operating the handle 72 even from the upper inspection port 32 of the rising portion 3.

In the case of the rainwater basin 1 of the present embodiment, the center 73 of the upper end portion of the handle 72 attached to the filter main body 71 is arranged eccentrically from the normal line 74 passing through the center of the attachment portion of the handle 72 on the filter main body 71. Therefore, the upper end portion of the handle 72 has a distance from the upper end portion on one side to the inner wall of the rising portion 3 in a plane parallel to the rotating surface of the mounted portion 70, and the rising portion from the upper end portion on the other side. It is arranged so as to be longer than the distance to the inner wall of 3.

Therefore, in the rainwater basin 1 of the present embodiment, the center 73 of the upper end portion of the handle 72 is rotated in the direction of rotation for mounting the filter main body 71 to the mounting pipe 34 from the normal line 74 passing through the center of the mounting portion of the handle 72. It can be eccentric and, in other words, arranged in a plane parallel to the rotating surface of the mounted portion 70.

In the rainwater basin 1 of the present embodiment, the filter 7 is mounted when the handle 72 of the filter 7 is in a state of being upright in a substantially vertical direction in a plane parallel to the rotating surface of the mounted portion 70 (FIGS. 4 and 5). It is set so as to be in the mounting position engaged with the tube 34, while the upper end portion of the handle 72 of the filter 7 is in a plane parallel to the rotating surface of the mounted portion 70, and the inner wall of the rising portion 3 from the upper end portion. The filter 7 is set so as to be in the detached position from the mounting pipe 34 when the filter 7 is in a state of being tilted (tilted) by rotating to the side having a long distance to. As described above, when the mounting position of the filter 7 is set when the handle 72 is in an upright position in a substantially vertical direction, it is easy to easily and accurately grasp the mounting state of the filter 7 both visually and tactilely. Become.

In the case of the present embodiment, the rotation stroke between the mounting position and the detaching position of the upper end portion of the handle 72 and the rotation angle of the mounted portion 70 (see FIGS. 5 and 8) are not shown, but the upper end of the handle 72 is shown. The rotation stroke and the angle of rotation when the center 73 of the portion is arranged on the normal line 74 passing through the center of the mounting portion of the handle 72 can be made longer and larger. When the center 73 of the upper end portion of the handle 72 is not eccentric from the normal line 74 passing through the center of the mounting portion of the handle 72 and is arranged on the normal line 74, the upper end portion of the handle 72 rotates the mounted portion 70. In a plane parallel to the surface, the distance from the upper end of one side to the inner wall of the rising portion 3 and the distance from the upper end of the other side to the inner wall of the rising portion 3 are equal to each other. For example, in a plan view, the rotation stroke can be effectively used only by half or less of the inner diameter of the rising portion 3.

Further, in the rainwater basin 1 of the present embodiment, for example, when the handle 72 of the filter 7 is in a state of being upright in a substantially vertical direction in a plane parallel to the rotating surface of the mounted portion 70 (FIGS. 4 and 5), the filter is used. 7 is set so as to be in a detached position from the mounting pipe 34, while the upper end portion of the handle 72 of the filter 7 is in a plane parallel to the rotating surface of the mounted portion 70, and the rising portion 3 from the upper end portion. The filter 7 may be set so as to be in the mounting position where the filter 7 is engaged with the mounting tube 34 when the filter 7 is in a state of being tilted (tilted) by rotating to the side where the distance to the inner wall of the is long. When the detachment position of the filter 7 is when the handle 72 is upright in the substantially vertical direction, the filter 7 is raised and lowered while the handle 72 is upright in the substantially vertical direction to the mounting port 35. Since the alignment can be performed, the operability of the filter 7 is improved.

In this way, when the center 73 of the upper end portion of the handle 72 is eccentric from the normal line 74 passing through the center of the mounting portion of the handle 72, the center 73 of the upper end portion of the handle 72 passes through the center of the mounting portion of the handle 72. Compared to the rainwater basin arranged on the 74, the rotation stroke of the upper end portion of the handle 72 and the rotation angle of the mounted portion 70 can be made longer and larger. For this reason, for example, the filter 7 may be installed in a rainwater basin 1 deeper downward from the inspection port 32 of the main body 2, or in a rainwater basin 1 installed at any height in the main body. If the handle 72 used in the present embodiment is applied, the filter 7 can be attached to the mounting pipe 34 by the bayonet method even from the upper inspection port 32 of the rising portion 3, basically regardless of the height of the rising portion 3. , It will be possible to secure the rotation angle required for removal.

In the rainwater basin 1 of the present embodiment, the rainwater control unit that is detachably attached to the attachment port 35 of the attachment pipe 34 includes a conical orifice (in addition to the filter 7 shown in FIGS. 10A to 10C). (Not shown), can be applied to check valves and the like.

Further, in the rainwater basin 1 of the present embodiment, the center 73 of the upper end portion of the handle 72 includes a normal line 74 passing through the center of the mounting portion of the handle 72, and the method is performed in a plane orthogonal to the rotation plane of the mounted portion 70. It is arranged eccentrically from the line 74 (see FIGS. 4 and 10C).

In the case of the rainwater basin 1 of the present embodiment, the center 73 of the upper end portion of the handle 72 includes the normal line 74 passing through the center of the mounting portion of the handle 72, and the handle is in a plane orthogonal to the rotation plane of the mounted portion 70. Since it is arranged eccentrically from the normal line 74 passing through the center of the mounting portion 72 toward the central axis 30 of the rising portion 3, the closer it is to the central axis 30 of the rising portion 3, the more it becomes the surface of revolution of the mounted portion 70. The distance from the inner wall of the rising portion 3 on one side to the inner wall of the rising portion 3 on the other side in the parallel plane is substantially equal to the inner diameter of the rising portion 3 and is the longest.

As described above, the rainwater basin 1 of the present embodiment has the center 73 of the upper end portion of the handle 72 from the normal line 74 passing through the center of the mounting portion of the handle 72 in a plane parallel to the rotating surface of the mounted portion 70. Since it is arranged eccentrically and is arranged eccentrically from the normal line 74 even in a plane including the normal line 74 and orthogonal to the rotation plane of the mounted portion 70, the internal space (inner diameter) of the rising portion 3 is arranged. By making the best use of it, the rotation stroke between the mounting position and the detaching position of the upper end portion of the handle 72 and the rotation angle of the mounted portion 70 can be set.

Further, in the rainwater basin 1 of the present embodiment, the handle portion 72 of the filter 7 is arranged so as to be parallel to the central axis 30 of the rising portion 3 of the rainwater basin 1 when the filter 7 is attached to the mounting pipe 34. (See Figures 4 and 5). In the present embodiment, most of the handles 72 of the filter 7 have a substantially linear rod shape, so that when they are arranged so as to be parallel to the central axis 30 of the rising portion 3, that is, when they are arranged in a substantially vertical direction. The risk of interference with the inner wall of the rising portion 3 is reduced by the rod-shaped portion of the handle 72 extending or bending in the lateral direction, and the internal space (inner diameter) of the rising portion 3 can be effectively utilized.

Next, the procedure for attaching and detaching the filter 7 of the present embodiment will be briefly described. The filter 7 of the present embodiment is in a mounted state in which the handle 72 is engaged with the mounting tube 34 in the main body 2 when the handle 72 is in an upright position in the vertical direction (FIGS. 4 and 5), while the handle 72 is in a mounted state. When it is tilted from the vertical direction (not shown), it is in a detached state from the mounting pipe 34 in the main body 2. Therefore, when the filter 7 in the mounted state is taken out from the inside of the main body 2, the handle 72 (FIGS. 4 and 5) in the vertical direction is first tilted toward the inner wall of the rising portion 3. After the filter 7 is disengaged from the mounting pipe 34, the filter 7 may be pulled up from the inspection port 32 of the main body 2 as it is via the handle 72.

In this case, the tilting direction of the handle 72 for detaching the filter 7 is such that, in the embodiment shown in FIG. 5, the distance from the upper end portion of the handle 72 to the inner wall of the rising portion 3 on the left side is the upper end of the handle 72. Since it is longer than the distance from the portion to the inner wall of the rising portion 3 on the right side, the rotation stroke of the handle 72 and the rotation angle of the mounted portion 70 are long and can be tilted toward the inner wall of the rising portion 3 on the left side. Become. Further, when the filter 7 in the detached state is attached to the attachment tube 34 in the main body 2, the reverse procedure of the above procedure may be executed.

On the contrary, when the handle 72 of the present embodiment is tilted from the vertical direction (not shown), the filter 7 is in a mounted state in which it is engaged with the mounting tube 34 in the main body 2. A case where the handle 72 is in an upright state in the vertical direction (FIGS. 4 and 5) and is in a detached state from the mounting pipe 34 in the main body 2 will be described.

In this case, when the external filter 7 is further inserted into the main body 2 and attached to the mounting pipe 34, the filter 7 is first inserted through the handle 72 while keeping the handle 72 upright in the vertical direction. Insert it into the main body 2. Then, after aligning the mounted portion 70 of the filter 7 with the mounting port 35 of the mounting pipe 34, the handle 72 (FIGS. 4 and 5) in an upright state is tilted toward the inner wall of the rising portion 3. The filter 7 is attached to the attachment tube 34.

In this case, the rotation direction of the handle 72 for mounting the filter 7 is such that, in the embodiment shown in FIG. 5, the distance from the upper end portion of the handle 72 to the inner wall of the rising portion 3 on the left side is from the upper end portion of the handle 72. Since it is longer than the distance to the inner wall of the rising portion 3 on the right side, the rotation stroke of the handle 72 and the rotation angle of the mounted portion 70 are long and large, and the handle is rotated toward the inner wall of the rising portion 3 on the left side. Further, when taking out the filter 7 in the mounted state from the inside of the main body 2 to the outside, the reverse procedure of the above procedure may be executed.

As described above, FIGS. 4, 5 and 8 show a cross-sectional view and a plan view of the rainwater basin 1 according to the present embodiment in which the filter 7 is attached to the attachment pipe 34 of the outlet 33. In 6, 7 and 9, a cross-sectional view and a plan view of the rainwater basin 1 according to the present embodiment in the embodiment in which the filter 7 is removed from the mounting pipe 34 of the outlet 33 are shown.

In the rainwater basin 1 of the present embodiment, a substantially cylindrical bottomed mud reservoir portion 4 having a bucket 5 that is detachably housed is connected to the lower portion of the rising portion 3 of the main body 2 and is connected to the rising portion. The inner diameter of 3 is larger than the outer diameter of the bucket 5, and the central shaft 30 of the rising portion 3 is eccentric to the outlet 33 side of the central shaft 40 of the mud reservoir portion 4.

As will be understood with reference to FIGS. It is larger than the outer diameter of the bucket 5 housed in the mud reservoir 4, and the central axis 30 of the rising portion 3 is eccentric to the outlet 33 side of the central axis 40 of the mud reservoir 4. Further, since the outer diameter of the bucket 5 is smaller than the inner diameter of the mud reservoir 4, if the inner diameter of the rising portion 3 is larger than the inner diameter of the mud reservoir 4, it will be larger than the outer diameter of the bucket 5 (see FIG. 9). ..

In the rainwater basin 1 of the present embodiment, since the inner diameter of the rising portion 3 is larger than the inner diameter of the mud collecting portion 4, the inner wall surface of the mud collecting portion 4 rises while being arranged in the inner region of the inner wall surface of the rising portion 3. The central axis 30 of the portion 3 can be arranged eccentrically with respect to the central axis 40 of the mud reservoir portion 4.

Further, in the rainwater basin 1 of the present embodiment, the central axis 30 of the rising portion 3 can be eccentric to the outlet 33 side of the central axis 40 of the mud reservoir portion 4, so that the mud reservoir portion 4 can be viewed in a plan view. The bucket 5 housed therein can be arranged at a position that does not overlap with the peripheral wall 31 of the rising portion 3, the mounting pipe 34 attached to the rising portion 3, and the inflow branch pipe 37 (see FIG. 9). In other words, in a plan view, the outer diameter of the bucket 5 housed in the mud reservoir 4 is the mounting port 35 of the mounting pipe 34 in the rising portion 3 and the end surface (inner wall surface) of the inflow port. Less than the distance between. Therefore, the rainwater basin 1 of the present embodiment can freely take in and out the bucket 5 from the mud reservoir 4 by a simple structure without using a complicated filter attachment / detachment mechanism or the like.

The main body 2 of the rainwater masu 1 is mainly composed of a substantially cylindrical rising portion 3 and a substantially cylindrical bottomed mud reservoir 4, but both do not necessarily have to be integrally formed. As in the present embodiment, the rising portion 3 and the mud reservoir portion 4 may be formed as separate and independent parts.

When the rising portion 3 and the mud collecting portion 4 are formed as separate parts as in the present embodiment, the rising portion 3 has a substantially cylindrical shape, so that a general-purpose circular pipe can be easily diverted to the rising portion 3. Become.

In the rainwater basin 1 of the present embodiment, as described above, the diameter of the rising portion 3 and the diameter of the mud reservoir 4 are different from each other, but the inner diameter of the upper receiving port 60 is larger than the inner diameter of the lower receiving portion 62. Moreover, since the central shaft 61 of the upper socket sandwiches the different diameter tubular joint 6 eccentric from the central shaft 63 of the lower socket between the rising portion 3 and the mud collecting portion 4, the rising portion 3 and the mud collecting portion 4 are sandwiched between the rising portion 3 and the mud collecting portion 4. Can be easily connected in any relative arrangement desired. Further, the rainwater basin 1 in which the rising portion 3 and the mud reservoir portion 4 are connected by using the different diameter tubular joint 6 as in the present embodiment has more freedom in design than the rainwater basin 1 in which both are integrally molded. On the contrary, the manufacturing cost can be significantly reduced.

The rising portion 3 of the present embodiment can be cut to an arbitrary height (length) in order to adjust the height of the rainwater basin 1, and a standardized general-purpose circular pipe can be used. can. Therefore, the rainwater stormwater 1 of the present embodiment can be installed at various depths of installation locations according to the installation environment at the construction site.

The mud reservoir 4 is a dedicated part for the rainwater basin 1, but as described above, it is connected to the lower part of the rising portion 3 via the different diameter pipe joint 6, so that it is arbitrary regardless of the diameter of the rising portion 3. It is possible to prepare the mud reservoir portion 4 having the diameter of the above, and it is possible to reduce the number of types of the mud reservoir portion 4 that must be manufactured.

The bucket 5 housed in the mud reservoir 4 is a bottomed tubular body, and has an outer diameter smaller than the inner diameter of the mud reservoir 4 in order to discharge the rainwater accumulated in the bucket 5 to the mud reservoir 4. It has a gap between it and the mud reservoir 4 (see FIGS. 8 and 9).

As will be understood with reference to FIGS. 1 to 3, the mud reservoir 4 of the present embodiment may or may not be provided with a plurality of vertically long water-permeable slits 41 on its side wall. The water permeable slit 41 may be replaced with a plurality of water permeable holes or a combination of the water permeable slits 41 and the water permeable holes 41. When the water permeable slit 41 is provided, the bucket 5 has a plurality of penetrations arranged at a position higher than the upper end of the water permeable slit 41 of the mud reservoir 4 when the bucket 5 is mounted in the mud reservoir 4. It is preferable to provide a hole (not shown). Further, the through hole of the bucket 5 may be replaced with a plurality of through slits or a combination of the through holes and the through slits.

As described above, even when a plurality of water permeable slits 41 are provided on the side wall so as to surround the bucket 5 at the lower part of the rainwater basin 1, the bucket 5 is detachably mounted in the mud reservoir portion 4. Rainwater containing foreign matter such as mud and dead leaves that has flowed in through the inflow branch 37 flows into the bucket 5, but since the lower region of the bucket 5 is not provided with a through hole, the rainwater that has flowed into the bucket 5 is once discharged. Foreign matter that stays in the lower region of the bucket 5 and is contained in rainwater or the like is deposited as it is in the lower region of the bucket 5. When rainwater or the like collects in the bucket 5, only the supernatant liquid such as rainwater accumulated in the bucket 5 is discharged to the outside of the bucket 5 through the through hole provided in the upper region of the bucket 5. The supernatant liquid such as rainwater discharged to is then drained to the outside of the mud reservoir 4 through the water permeation slit 41 provided in the mud reservoir 4.

Therefore, if a plurality of water-permeable slits 41 are provided on the side wall of the mud reservoir 4 as described above, and a through hole is provided in the bucket at a position higher than the upper end of the water-permeable slit 41 of the mud reservoir 4, rainwater will be collected. Does function even if it penetrates, and foreign matter contained in rainwater etc. will remain in the lower area inside the bucket 5, so the foreign matter will be rainwater, so the crushed stone tank spread outside the rainwater 1 (not shown) ) Will not flow out, and clogging of the crushed stone tank can be prevented.

Further, since the bucket 5 mounted in the mud reservoir 4 is removable as described above, the bucket 5 is further pulled out from the inspection port 32 of the main body 2 to remove the accumulated foreign matter, and the bucket 5 is removed. Since it can be done by an extremely simple work such as discarding the foreign matter in 5, the maintainability of the rainwater 1 is improved.

In the rainwater basin 1 of the present embodiment, either one of the water permeable slit 41 of the mud reservoir 4 or the through hole of the bucket 5 may be omitted, or both the water permeable slit 41 and the through hole may be omitted. good. If the water permeation slit 41 of the mud reservoir 4 is omitted, the rainwater basin 1 will not function as it permeates, but it can be used as a normal rainwater basin 1.

The rainwater basin 1 of the present embodiment has an inflow branch pipe 37 (on the right side of FIGS. As an outlet for letting rainwater etc. flow out from 1 to the outside, the mounting pipe 34 (on the right side of FIGS. It is attached to the peripheral wall of the rising pipe 3 so as to have a mirror-symmetrical arrangement in which the orientation is changed by 180 ° in the horizontal direction.

Since the inflow branch pipe 37 of the present embodiment is provided on the peripheral wall of the rising portion 3 and can be retrofitted to the inflow side opening 36, the installation level and direction of the main body 2 are adjusted according to the connection position of the external inflow pipe. The inflow branch pipe 37 can be attached to the rising portion 3 at a free position (height, direction) in any direction without any problem. The inflow side opening 36 can be provided at an arbitrary position on the peripheral wall of the rising portion 3 by hollowing out the peripheral wall of the rising portion 3 using a hole saw or the like at a construction site or the like.

As shown in FIGS. 1, 4, and 6, the inflow branch 37 of the present embodiment has a branch main body 38 having a receiving port connected to an external inflow pipe, and a rising portion 3 for supporting the branch main body 38. It is composed of a flange tube 39 having a flange portion bonded to the outer wall surface. The inside of the receiving port of the branch pipe main body 38 has a tapered portion (or a stepped portion) whose diameter is reduced inward in order to bring the tip end portion of the external inflow pipe into contact with the flange of the flange pipe 39. The portion is curved along the outer wall surface of the rising pipe 3 (see FIG. 1).
