It has an inspection cylinder portion in which an inspection port that opens toward the surface is formed. The flow path switching member has a side wall portion on which the first opening and the second opening are formed, and a bottom wall portion on which an invert connecting the first opening and the second opening is formed. The handle is bridged over the side wall portion of the flow path switching member. The flow path switching member has a first position where the first opening and the inflow port overlap and the second opening and the first outflow port overlap with respect to the main body, and the second opening and the flow. It is configured so that it can be arranged at a second position where the inlet overlaps and the first opening and the second outlet overlap. The handle has a grip portion and a shaft portion extending from an end portion of the grip portion. The flow path switching member is formed with an engaging portion in which the shaft portion of the handle is engaged. The main body has an engaging hole for engaging the shaft portion of the handle and a connecting portion provided on the peripheral wall portion of the main body. The handle is a portion that moves when the flow path switching member is arranged at the first position and when the flow path switching member is arranged at the second position, and the flow path switching member is arranged at the first position. It has a confirmation unit that can be visually recognized through the inspection port of the main body when it is being operated and when it is arranged at the second position.

According to the above piping member, by pulling the handle in the first direction, the flow path switching member can be taken out from the first position or the second position to the outside of the main body through the inspection port. On the contrary, by moving the handle in the direction opposite to the first direction, the flow path switching member can be inserted into the main body and can be arranged at the first position or the second position. When the flow path switching member is arranged at the first position, the inflow port and the first outflow port communicate with each other, and the drainage flows from the inflow port to the first outflow port. When the flow path switching member is arranged at the second position, the inflow port and the second outflow port communicate with each other, and the drainage flows from the inflow port to the second outflow port. According to the above piping member, the drainage flow path can be switched by changing the position of the flow path switching member by using the handle in this way. Further, according to the piping member, the confirmation portion of the handle moves when the flow path switching member is arranged at the first position and the second position by using the handle. Then, when the flow path switching member is arranged at the first position and when it is arranged at the second position, the confirmation unit is visually recognized through the inspection port. Therefore, according to the above piping member, it is possible to confirm that the flow path switching member is correctly arranged in the first position and that the flow path switching member is correctly arranged in the second position only by visually observing the confirmation portion of the handle. can.

According to a preferred aspect of the present invention, the shaft portion of the handle is rotatable with respect to the engaging portion of the flow path switching member, and is inside the engaging hole of the connecting portion of the main body. It is configured to be rotatable in. The confirmation portion is composed of a side surface of the grip portion or the shaft portion of the handle.

According to the above aspect, the flow path switching member is arranged at the first position or the second position by rotating the handle. When the flow path switching member is correctly arranged in the first position or the second position, the side surface of the grip portion or the shaft portion of the handle is directed in the first direction and is visually recognized through the inspection port. In this way, the grip portion of the handle or the side surface of the shaft portion can be used as the confirmation portion.

According to a preferred aspect of the present invention, the engaging hole is located in a guide groove extending in a second direction opposite to the first direction and on the second direction side of the guide groove. It includes a storage groove that is wider than the guide groove. The shaft portion includes a central portion and a protrusion portion that protrudes outward in the radial direction from the central portion. A corner portion that comes into contact with the protrusion when the handle is rotated is provided between the guide groove and the accommodating groove.

According to the above aspect, when the shaft portion of the handle is moved along the guide groove and then the handle is rotated, the protruding portion of the shaft portion comes into contact with the corner portion. Therefore, the handle can be rotated by using the principle of the lever. Since the handle can be rotated with a smaller force, the flow path switching member can be easily arranged at the first position or the second position. Therefore, the flow path can be easily switched.

According to a preferred aspect of the present invention, the inside of the accommodating groove is provided with a protrusion that projects toward the guide groove and comes into contact with the protrusion when the handle is rotated.

According to the above aspect, when the flow path switching member is removed from the first position or the second position, when the handle is rotated, the protrusion of the shaft portion comes into contact with the protrusion of the accommodating groove. Therefore, the handle can be rotated in the opposite direction by using the principle of the lever. Since the handle can be rotated in the opposite direction with a smaller force, the flow path switching member can be easily removed from the first position or the second position. Therefore, the flow path can be easily switched.

According to a preferred embodiment of the present invention, the engaging portion of the flow path switching member is formed of a through hole through which the shaft portion of the handle is penetrated. The grip portion of the handle has a first inclined surface that is inclined from the first direction so as to go toward the peripheral wall portion of the flow path switching member toward the first direction side. The handle has an inclined portion that is integrated with the shaft portion and has a second inclined surface that is parallel to the first inclined surface. The grip portion is assembled on the inclined portion so that the first inclined surface and the second inclined surface face each other and slide with each other. The confirmation portion is composed of a part of the second inclined surface of the inclined portion or a part of the shaft portion.

According to the above aspect, when the grip portion is pushed in the direction opposite to the first direction, the grip portion slides with respect to the inclined portion. Since the first inclined surface of the grip portion and the second inclined surface of the inclined portion are inclined, when the grip portion moves in the direction opposite to the first direction, the inclined portion and the shaft portion are separated from the grip portion (hereinafter, hereinafter, Move to the outside). As a result, the shaft portion of the handle is fitted into the engaging hole of the connecting portion of the main body, and the flow path switching member is correctly arranged at the first position or the second position. Here, when the grip portion moves outward, a part of the second slope of the inclined portion or a part of the shaft portion becomes visible through the inspection port. Therefore, a part of the second slope of the inclined portion or a part of the shaft portion can be used as the confirmation portion.

According to a preferred aspect of the present invention, the confirmation portion is colored differently from the surroundings of the confirmation portion.

According to the above aspect, the confirmation portion can be easily distinguished from the surroundings. Therefore, the confirmation unit can be easily visually recognized, and it can be easily confirmed that the flow path switching member is correctly arranged at the first position and correctly arranged at the second position.

According to a preferred aspect of the present invention, the peripheral wall portion of the main body includes a first peripheral wall portion in which the first outlet is formed, a second peripheral wall portion in which the second outlet is formed, and the flow. It has a third peripheral wall portion on which an entrance is formed. The first peripheral wall portion, the second peripheral wall portion, and the third peripheral wall portion are arranged in a triangular shape when viewed along the first direction, and are separated from each other toward the first direction. As described above, it is inclined from the first direction. The side wall portion of the flow path switching member has a first side wall portion in which the first opening is formed, a second side wall portion in which the second opening is formed, and a third side wall portion. The first side wall portion, the second side wall portion, and the third side wall portion are arranged in a triangular shape when viewed along the first direction, and are separated from each other toward the first direction. As described above, it is inclined from the first direction. The flow path switching member has a closing member parallel to the third side wall portion and slidably engaged with the third side wall portion, and a sealing member provided on the closing member.

Slide. By sliding the third side wall portion, the closing member is pressed against the first peripheral wall portion or the second peripheral wall portion by the third side wall portion. Therefore, the closing member can be brought into close contact with the first peripheral wall portion or the second peripheral wall portion of the main body while suppressing the sliding resistance when the flow path switching member is inserted into the main body to be small. Therefore, the flow path can be switched with a smaller force, the sealing property of the second outlet when the flow path switching member is arranged at the first position, and when the flow path switching member is arranged at the second position. The sealing property of the first outlet of the above can be improved, and the leakage of drainage can be prevented more reliably. On the other hand, in such a flow path switching member, when the flow path switching member is arranged at the first position or the second position, the closing member must be pressed against the first peripheral wall portion or the second peripheral wall portion, but the closing member May stop at a position where it is not pressed sufficiently. Therefore, there is a possibility that the operator finishes the flow path switching operation without the flow path switching member being correctly arranged at the first position or the second position. However, according to the above aspect, by visually recognizing the confirmation unit as described above, it is confirmed that the flow path switching member is correctly arranged in the first position and correctly arranged in the second position. Can be done. Therefore, the flow path can be reliably switched.

According to the present invention, in a piping member capable of switching a flow path, it is confirmed whether or not the flow path switching member is correctly arranged at both the first position and the second position only by visually observing through the inspection port. be able to.

As shown in FIG. 4, the second peripheral wall portion 15B is inclined from the vertical line so as to approach the center of the bottom wall portion 14 as it goes downward. Similarly, the first peripheral wall portion 15A and the third peripheral wall portion 15C are inclined from the vertical line so as to approach the center of the bottom wall portion 14 toward the lower side. In other words, the first peripheral wall portion 15A, the second peripheral wall portion 15B, and the third peripheral wall portion 15C are inclined from the vertical line so as to be separated from each other toward the upper side.

As shown in FIG. 2, a first outlet 11 is formed in the first peripheral wall portion 15A, a second outlet 12 is formed in the second peripheral wall portion 15B, and an inflow port 13 is formed in the third peripheral wall portion 15C. It is formed. The inflow port 13, the first outflow port 11, and the second outflow port 12 have the same inner diameter and are opened in the horizontal direction.

A first connecting portion 61 is provided above the intersection of the first peripheral wall portion 15A and the third peripheral wall portion 15C. As shown in FIG. 3, a second connecting portion 62 is provided on the upper portion of the second peripheral wall portion 15B. A third connecting portion 63 is provided above the intersection of the second peripheral wall portion 15B and the third peripheral wall portion 15C. A fourth connecting portion 64 is provided above the first peripheral wall portion 15A. Engagement holes 30 are formed in the first to fourth connecting portions 61 to 64. The engaging hole 30 of the first connecting portion 61 and the engaging hole 30 of the second connecting portion 62 face each other with the center 5c of the main body 5 interposed therebetween. The engaging hole 30 of the third connecting portion 63 and the engaging hole 30 of the fourth connecting portion 64 face each other with the center 5c of the main body 5 interposed therebetween. In the following description, unless otherwise specified, the direction closer to the center 5c of the main body 5 is referred to as the radial inner direction, and the direction away from the center 5c is referred to as the radial outer direction.

In the present embodiment, the connecting portions 61 to 64 are separate members from the peripheral wall portions 15A to 15C, and are assembled to the peripheral wall portions 15A to 15C. However, the connecting portions 61 to 64 may be integrated with the peripheral wall portions 15A to 15C. The connecting portions 61 to 64 and the peripheral wall portions 15A to 15C may be a single member. In FIG. 2, the fourth connecting portion 64 is not shown.

As shown in FIG. 1, the horizontal cylinder portion 21 extends outward in the radial direction from the first peripheral wall portion 15A. As shown in FIG. 3, the first outflow pipe 91 is connected to the horizontal cylinder portion 21. The horizontal cylinder portion 22 extends outward in the radial direction from the second peripheral wall portion 15B, and the second outflow pipe 92 is connected to the horizontal cylinder portion 22. The horizontal cylinder portion 23 extends outward in the radial direction from the third peripheral wall portion 15C, and the inflow pipe 93 is connected to the horizontal cylinder portion 23. As shown in FIG. 1, the inspection cylinder portion 20 extends upward from the main portion 10. The inspection cylinder portion 20 is open upward, and the opening of the inspection cylinder portion 20 constitutes the inspection port 19. A lid 16 is detachably fitted into the inspection port 19.

Next, the flow path switching member 35 will be described. The flow path switching member 35 is a member that partitions the internal flow path of the drainage basin 1 and enables switching of the flow path. As shown in FIG. 5, the flow path switching member 35 has a flow path member 38 and a closing member 37.

The flow path member 38 has a bottom wall portion 49 (see FIG. 4) and a side wall portion 36. The side wall portion 36 includes a first side wall portion 36A, a second side wall portion 36B, and a third side wall portion 36C arranged in a triangular shape when viewed from above or below. Similar to the first peripheral wall portion 15A, the second peripheral wall portion 15B, and the third peripheral wall portion 15C of the main body 5, the first side wall portion 36A, the second side wall portion 36B, and the third side wall portion 36C have bottoms as they go downward. It is tilted from the vertical line so as to approach the center of the wall portion 49 (see FIG. 4). The first side wall portion 36A, the second side wall portion 36B, and the third side wall portion 36C are inclined from the vertical line so as to be separated from each other toward the upper side.

A first opening 41 is formed in the first side wall portion 36A, and a second opening 42 is formed in the second side wall portion 36B. The bottom wall portion 49 is formed with an invert (groove-shaped flow path through which drainage flows) 57 connecting the first opening 41 and the second opening 42. No opening is formed in the third side wall portion 36C. Rails 39 having slide grooves 39a extending vertically are provided on both sides of the third side wall portion 36C. A connecting portion 43 in which a through hole 45 is formed is provided in the upper portion of the intersection of the first side wall portion 36A and the second side wall portion 36B and the upper portion of the third side wall portion 36C.

The closing member 37 is a member for sealing the first outlet 11 or the second outlet 12 when the flow path switching member 35 is mounted on the main body 5. The closing member 37 is provided with an annular sealing member 48. The sealing member 48 is made of rubber, for example, and has flexibility. When the closing member 37 is pressed against the first peripheral wall portion 15A of the main body 5, the sealing member 48 seals the periphery of the first outlet 11, and the closing member 37 is further pressed against the second peripheral wall portion 15B of the main body 5. When pressed, the periphery of the second outlet 12 is sealed.

The closing member 37 is formed in a plate shape and is configured to be slidable up and down with respect to the flow path member 38. As shown in FIG. 6, on both sides of the closing member 37, engaging projections 47 that engage with the slide groove 39a of the rail 39 of the flow path member 38 are provided. As shown in FIG. 7, the lower end of the slide groove 39a of the rail 39 is closed, and when the engaging protrusion 47 slides to the lower end of the slide groove 39a, the engaging protrusion 47 is supported by the lower end of the rail 39. It has become so. This prevents the engaging protrusion 47 from falling off downward. Therefore, when the flow path member 38 is lifted, the closing member 37 is prevented from falling off (see FIG. 9).

Next, the handle 50 will be described. The handle 50 is a portion that the operator grasps when the flow path switching member 35 is removed from the main body 5 and when it is attached to the main body 5. As shown in FIG. 5, the handle 50 is bridged over the side wall portion 36 of the flow path switching member 35.

The handle 50 has a grip portion 51 and shaft portions 52 extending from both ends of the grip portion 51. The shape of the grip portion 51 is not limited in any way, but here it is formed in a bent plate shape. The side surface 53 of the grip portion 51 is colored differently from the other portions of the grip portion 51 (in FIGS. 3 and 5, the above colors are indicated by cross-hatching). Here, the color of the side surface 53 is yellow, and the color of the portion other than the side surface 53 is gray. However, the color of the side surface 53 and the color of the portion other than the side surface 53 are not particularly limited.

The handle 50 is more rotatable with respect to the main body 5. Hereinafter, the state in which the side surface 53 of the grip portion 51 faces sideways is referred to as a state in which the handle 50 is standing. The state in which the side surface 53 faces upward (the state shown in FIGS. 3 and 5) is referred to as a state in which the handle 50 is tilted.

The shaft portion 52 is formed in a rod shape and penetrates through the through hole 45 of the connecting portion 43 of the flow path switching member 35. As a result, the shaft portion 52 is rotatably connected to the connecting portion 43. As shown in FIG. 5, the shaft portion 52 includes a cylindrical portion 52a as a central portion and a protruding portion 52b protruding from the cylindrical portion 52a in the radial direction of the shaft portion 52.

8 (a) to 8 (e) are views showing the engagement state between the shaft portion 52 of the handle 50 and the connecting portions 61 to 64 of the main body 5. Each engaging hole 30 of each connecting portion 61 to 64 includes a guide groove 30a extending vertically and a housing groove 30b located below the guide groove 30a. The width 30Wb of the accommodating groove 30b is larger than the width 30W of the guide groove 30a.

The guide groove 30a is configured to guide the vertical movement of the shaft portion 52 while restricting the rotation of the shaft portion 52. In the cross section of the shaft portion 52, assuming that the diameter of the cylindrical portion 52a is d1 and the dimension of the shaft portion 52 with respect to the protruding direction of the protrusion 52b is d2, the width 30W of the guide groove 30a is larger than d1 and more than d2. Is also small. The width 30Wb of the accommodating groove 30b is larger than d2. The accommodating groove 30b has a dimension in which the shaft portion 52 can be rotated.

The materials of the main body 5, the flow path switching member 35 (excluding the seal member 48), and the handle 50 are not particularly limited, but are made of a resin material here.

The flow path switching member 35 can be arranged at a first position connecting the inflow port 13 and the first outflow port 11 of the main body 5 and a second position connecting the inflow port 13 and the second outflow port 12. FIG. 3 shows a state in which the flow path switching member 35 is arranged at the first position. At the first position, the first opening 41 of the flow path switching member 35 overlaps with the inflow port 13 of the main body 5, the second opening 42 overlaps with the first outflow port 11, and the second outflow port 12 is closed by the closing member 37. It comes off. As a result, the inflow port 13 and the first outflow port 11 communicate with each other, and the drainage flowing in from the inflow port 13 flows out from the first outflow port 11. The drainage flows from the inflow pipe 93 to the first outflow pipe 91 via the drainage pipe 1. The second position is a position in which the flow path switching member 35 is rotated counterclockwise by 120 degrees in FIG. At the second position, the first opening 41 of the flow path switching member 35 overlaps with the second outlet 12 of the main body 5, the second opening 42 overlaps with the inflow 13, and the first outlet 11 is closed by the closing member 37. It comes off. As a result, the inflow port 13 and the second outflow port 12 communicate with each other, and the drainage flowing in from the inflow port 13 flows out from the second outflow port 12. The drainage flows from the inflow pipe 93 to the second outflow pipe 92 via the drainage pipe 1. By changing the position of the flow path switching member 35 in this way, the flow path of the drainage basin 1 can be switched.

Next, a method of switching the flow path of the drainage basin 1 will be described. Here, a method of changing the position of the flow path switching member 35 from the first position to the second position will be described.

As described above, FIG. 3 shows a state in which the flow path switching member 35 is arranged at the first position. When the flow path switching member 35 is in the first position, one shaft portion 52 of the handle 50 is engaged with the engagement hole 30 of the first connecting portion 61 of the main body 5, and the other shaft portion 52 is the first. 2 It is engaged with the engaging hole 30 of the connecting portion 62. When the flow path switching member 35 is in the first position, the handle 50 is in a tilted state.

When switching the flow path, the operator first removes the lid 16 (see FIG. 1) and opens the inspection port 19 of the main body 5. Next, the arm is inserted from the inspection port 19, the grip portion 51 of the handle 50 is grasped, and the arm is pulled up. As a result, the handle 50 rotates, and the handle 50 changes from a fallen state to a standing state. At this time, as shown in the order of (e) → (d) → (c) → (b) in FIG. 8, the shaft portion 52 of the handle 50 has the engaging holes of the first connecting portion 61 and the second connecting portion 62. It rotates inside 30. Then, after the handle 50 is in a standing state (see FIG. 8B), the shaft portion 52 moves upward along the guide groove 30a, and the first connecting portion 61 and the second connecting portion 62 are engaged with each other. It is pulled out from the hole 30.

Since the handle 50 and the flow path member 38 are connected, when the handle 50 is pulled up, the flow path member 38 until the engaging projection 47 of the closing member 37 hits the lower end of the slide groove 39a of the rail 39 (see FIG. 7). Slides upward with respect to the closing member 37 (see FIG. 9). Then, after the engaging projection 47 hits the lower end of the slide groove 39a, the closing member 37 moves upward together with the flow path member 38. As described above, the third side wall portion 36C of the flow path member 38 is inclined with respect to the vertical line (see FIG. 4). Therefore, as the flow path member 38 slides upward, the force that presses the closing member 37 against the second peripheral wall portion 15B of the main body 5 is weakened. As a result, the adhesive force between the seal member 48 of the closing member 37 and the second peripheral wall portion 15B of the main body 5 is weakened. According to the present embodiment, since the adhesion force is weakened before the closing member 37 is pulled up, the sliding resistance between the seal member 48 and the second peripheral wall portion 15B when the flow path switching member 35 is pulled up becomes small. .. Therefore, the operator can pull up the flow path switching member 35 with a relatively small force.

After the operator takes out the flow path switching member 35 from the main body 5, the shaft portion 52 of the handle 50 holds the handle 50, and the shaft portion 52 of the handle 50 is true of the engagement hole 30 of the third connecting portion 63 and the fourth connecting portion 64. The flow path switching member 35 is rotated horizontally by 120 degrees so that it is located above. Then, the flow path switching member 35 is inserted downward with respect to the main body 5.

When the flow path switching member 35 is inserted, the seal member 48 of the closing member 37 comes into contact with the first peripheral wall portion 15A of the main body 5. However, since the closing member 37 is displaced downward from the third side wall portion 36C of the flow path member 38, the sliding resistance between the sealing member 48 and the first peripheral wall portion 15A is relatively small. Therefore, the operator can insert the flow path switching member 35 into the main body 5 with a relatively small force.

When the operator moves the handle 50 downward, the lower end portion of the closing member 37 first hits the bottom wall portion 14 of the main body 5. When the handle 50 is further moved downward, the flow path member 38 slides downward with respect to the closing member 37. Since the third side wall portion 36C of the flow path member 38 is inclined with respect to the vertical line, a part of the force for pushing the flow path member 38 downward causes the closing member 37 to be applied to the first peripheral wall portion 15A of the main body 5. It becomes a pressing force. Therefore, the operator can press the seal member 48 of the closing member 37 against the first peripheral wall portion 15A simply by pushing the handle 50 downward, and the sealing property of the seal member 48 can be improved. Thereby, it is possible to more reliably prevent the drainage from leaking from the first outlet 11.

As shown in FIGS. 8A and 8B, when the shaft portion 52 of the handle 50 is inserted into the engagement hole 30 of the third connecting portion 63 and the fourth connecting portion 64, the shaft portion 52 becomes a guide groove. It is guided downward along 30a. Then, as shown in the order of FIG. 8B → (c) → (d) → (e), the operator rotates the handle 50 from the standing state to the tilted state. As shown in FIG. 8C, a corner portion 30c is provided between the guide groove 30a and the accommodating groove 30b. Therefore, when the protrusion 52b of the shaft portion 52 comes into contact with the corner portion 30c, the handle 50 can be rotated by utilizing the principle of the lever. Therefore, the operator can rotate the handle 50 with a smaller force.

As shown in FIG. 8E, when the flow path switching member 35 is correctly arranged at the second position, the shaft portion 52 is accommodated in the accommodating groove 30b, and the handle 50 is in a tilted state. Conversely, as shown in FIG. 8E, when the handle 50 is in the tilted state, the flow path switching member 35 is correctly arranged at the second position. On the other hand, as shown in FIGS. 8 (b) to 8 (d), the flow path switching member 35 is not correctly arranged at the second position unless the handle 50 is in a tilted state. If the flow path switching member 35 is not correctly arranged at the second position, it is between the first side wall portion 36A of the flow path switching member 35 and the second peripheral wall portion 15B of the main body 5, or with the second side wall portion 36B. There is a risk that drainage will leak due to a gap between the wall and the third peripheral wall portion 15C. Alternatively, the closing member 37 cannot be sufficiently pressed against the first peripheral wall portion 15A, and drainage may leak from the first outlet 11.

According to the present embodiment, it is possible to confirm whether or not the flow path switching member 35 is correctly arranged at the second position based on whether or not the handle 50 is in a tilted state. When the handle 50 is standing, the side surface 53 of the handle 50 faces sideways, so that it cannot be visually recognized from the inspection port 19. On the other hand, when the handle 50 is tilted down, the side surface 53 of the handle 50 faces upward, so that the handle 50 can be visually recognized from the inspection port 19. In the present embodiment, the side surface 53 of the handle 50 functions as a confirmation unit for confirming that the flow path switching member 35 is correctly arranged.

Drainage 1 is buried underground, but the depth of drainage 1 from the ground surface varies. When the drainage basin 1 is buried in a relatively deep place, the inspection cylinder portion 20 (see FIG. 1) is extended upward, or another inspection cylinder portion is connected on the inspection cylinder portion 20. (In this case, the upper opening of the top inspection cylinder is the inspection port). When the drainage 1 is buried in a relatively deep place, it is difficult to judge whether or not the flow path switching member 35 is correctly arranged with respect to the main body 5 only by visually observing the flow path switching member 35. There is. However, according to the present embodiment, it is possible to easily confirm that the flow path switching member 35 is correctly arranged with respect to the main body 5 by visually observing whether or not the handle 50 is in a tilted state. Can be done.

After arranging the flow path switching member 35 at the second position as described above, the operator visually observes the side surface 53 of the handle 50 to grasp that the handle 50 is in a tilted state. In this way, it is confirmed that the flow path switching member 35 is correctly arranged at the second position. Then, after the confirmation is completed, the inspection port 19 is covered with the lid 16.

As described above, the position of the flow path switching member 35 can be changed from the first position to the second position, and the flow path of the drainage basin 1 can be switched.

Although the description is omitted, the work of changing the position of the flow path switching member 35 from the second position to the first position can be performed in the same manner. However, in this case, the shaft portion 52 of the handle 50 is pulled out from the engaging holes 30 of the third connecting portion 63 and the fourth connecting portion 64 of the main body 5, and the first connecting portion 61 and the second connecting portion 62 are engaged. It will be inserted into the joint hole 30.

As described above, according to the drainage basin 1 according to the present embodiment, the operator can change the position of the flow path switching member 35 by using the handle 50, and can switch the flow path. Further, it is possible to confirm whether or not the flow path switching member 35 is arranged at the correct position by using the handle 50. In the present embodiment, the side surface 53 of the handle 50 is a portion that moves when the flow path switching member 35 is arranged at the first position and the second position, and the flow path switching member 35 is the first. It is a part that is visually recognized through the inspection port 19 of the main body 5 when it is arranged at the 1st position and when it is arranged at the 2nd position. By simply visually observing the side surface 53 of the handle 50 through the inspection port 19, the operator can easily both that the flow path switching member 35 is correctly arranged in the first position and that the flow path switching member 35 is correctly arranged in the second position. Can be confirmed in.

Further, according to the present embodiment, since the side surface 53 is a part of the handle 50, it is not necessary to separately provide a dedicated confirmation unit. The handle 50 used when changing the position of the flow path switching member 35 can be used as a confirmation unit. Therefore, it is not necessary to increase the number of parts in order to provide the confirmation unit.

The color of the side surface 53 of the handle 50 may be the same as the color of other parts (for example, the upper surface of the handle 50), but in the present embodiment, the side surface 53 of the handle 50 is around the side surface 53 of the handle 50. Is colored differently from. Therefore, the side surface 53 of the handle 50 can be easily visually recognized. Therefore, it can be easily confirmed that the flow path switching member 35 is correctly arranged at the first position and that the flow path switching member 35 is correctly arranged at the second position.

The confirmation portion of the handle 50 is not limited to the side surface 53. A portion that moves when the flow path switching member 35 is arranged at the first position and when it is arranged at the second position, and when the flow path switching member 35 is arranged at the first position and at the second position. Any part that is visually recognized through the inspection port 19 when it is arranged in can be used as a confirmation unit. For example, the side surface of the shaft portion 52 of the handle 50 (the portion subjected to cross-hatching in FIG. 5) may be used as the confirmation portion. In this case as well, the side surface of the shaft portion 52 may be colored differently from the surroundings so that the confirmation portion can be easily visually recognized.

As shown in FIG. 10, a protrusion 30d protruding toward the guide groove 30a may be provided at the bottom of the accommodation groove 30b. As shown in the order of FIG. 10A → (b) → (c) → (d) → (e), when the handle 50 is rotated from the tilted state to the standing state, the protrusion of the shaft portion 52 52b comes into contact with the protrusion 30d of the guide groove 30a. Thereby, the handle 50 can be rotated in the opposite direction by utilizing the principle of the lever. Therefore, the handle 50 can be rotated in the opposite direction with a smaller force, and the work of removing the flow path switching member 35 from the main body 5 becomes easier.

(Second Embodiment)
Next, the drainage basin 1 according to the second embodiment will be described. In the following description, the same members and parts as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

As shown in FIG. 11, the drainage basin 1 according to the second embodiment includes a main body 5 including a main part 10 and a flow path switching member 35, similarly to the drainage basin 1 according to the first embodiment. .. Further, the drainage basin 1 according to the second embodiment is provided with a handle 150. 11 and 12 are perspective views and plan views of the main body 10, the flow path switching member 35, and the handle 150, respectively. FIG. 13 is a cross-sectional view taken along the line XIII-XIII of FIG. FIG. 14 is a perspective view of the flow path switching member 35 and the handle 150.

The handle 150 of the second embodiment has a different configuration from the handle 50 of the first embodiment. The flow path switching member 35 of the second embodiment is different from the flow path switching member 35 of the first embodiment in the shape of the through hole 45 of the connecting portion 43, but is the same except for the shape of the through hole 45. The main body 5 of the second embodiment is different from the main body 5 of the first embodiment in the shape of each connecting portion 61 to 64, but is the same except for the above.

As shown in FIG. 14, the handle 150 has a grip member 151 and support members 160 arranged on both sides of the grip member 151.

The grip member 151 includes a grip portion 151a and inclined portions 151b provided at both ends of the grip portion 151a. Here, the grip portion 151a and each inclined portion 151b are formed in a plate shape, but their shapes are not particularly limited. The inclined portion 151b is inclined from the vertical line toward the peripheral wall portion 36 (in other words, outward in the radial direction) as it goes upward. The distance between the two inclined portions 151b becomes smaller toward the bottom. The outer surface (first inclined surface) 171 of the inclined portion 151b is provided with a protrusion 154 protruding outward. The grip member 151 is composed of a single component, and the grip portion 151a, both inclined portions 151b, and both protrusions 154 are integrally formed of, for example, a resin material.

The support member 160 is a member that connects the gripping member 151 and the flow path switching member 35 and slidably supports the gripping member 151 up and down. The support member 160 includes an inclined portion 155 and a shaft portion 152 extending outward from the inclined portion 155.

The inclined portion 155 is formed in a plate shape. The shaft portion 152 is also formed in a plate shape, and the cross-sectional shape of the shaft portion 152 is formed in a substantially quadrangular shape. However, the shapes of the inclined portion 155 and the shaft portion 152 are not particularly limited. Like the inclined portion 151b of the gripping member 151, the inclined portion 155 is inclined from the vertical line so as to approach the center of the flow path switching member 35 toward the lower side. The distance between the inclined portions 155 of both support members 160 becomes smaller toward the bottom.

The inner surface (second inclined surface) 172 of the inclined portion 155 is parallel to the outer surface (first inclined surface) 171 of the inclined portion 151b and faces the outer surface 171. A slide groove 156 is formed on the inner surface 172 of the inclined portion 155. The slide groove 156 is engaged with the protrusion 154 of the inclined portion 151b of the gripping member 151. The slide groove 156 serves to guide the protrusion 154 up and down. As shown in FIG. 15, the lower end portion 154b of the protrusion 154 of the inclined portion 155 has a wider width than the portion 154a above the lower end portion 154b. A stepped surface 154c is provided on the upper side of the lower end portion 154b. On the other hand, the upper portion 156a of the slide groove 156 has a width smaller than that of the lower portion 156b, and a stepped surface 156c is provided between the upper portion 156a and the lower portion 156b. When the stepped surface 154c of the protrusion 154 and the stepped surface 156c of the slide groove 156 come into contact with each other, the upward movement of the protrusion 154 is restricted. The stepped surface 154c and the stepped surface 156c form a stopper that regulates the protrusion 154 from coming out of the slide groove 156 upward. This stopper prevents the gripping member 151 from coming off the support member 160 upward when the operator lifts the gripping member 151, and prevents the flow path switching member 35 from falling.

As shown in FIG. 14, the shaft portion 152 extends outward from the lower portion of the inclined portion 155. The shaft portion 152 is connected to the connecting portion 43 by penetrating the through hole 45 of the connecting portion 43 of the flow path switching member 35. The shaft portion 152 is inserted into the engaging holes 130 of the connecting portions 61 to 64 of the main body 5 when the flow path switching member 35 is mounted on the main body 5. As shown in FIG. 16, the shaft portion 152 has a root portion 152a and a tip portion 152b having different vertical widths. The vertical width of the tip portion 152b is smaller than the vertical width of the root portion 152a, and a stepped surface 152c is formed between the root portion 152a and the tip portion 152b.

As shown in FIG. 14, in the present embodiment, the through hole 45 of the connecting portion 43 of the flow path switching member 35 is formed in a shape suitable for the cross-sectional shape of the shaft portion 152 of the handle 150. That is, since the cross-sectional shape of the shaft portion 152 is formed in a substantially quadrangular shape, the contour shape of the through hole 45 is formed in a substantially quadrangular shape.

In the present embodiment, the engaging hole 130 of the main body 5 includes a slide groove 131 extending vertically and a fitting hole 132 extending radially outward from the lower end portion of the slide groove 131. The contour shape of the fitting hole 132 is formed to match the cross-sectional shape of the shaft portion 152 of the handle 150, and is formed in a substantially quadrangular shape. The slide groove 131 of the engaging hole 130 is not always necessary and can be omitted.

Also in the present embodiment, the flow path switching member 35 has a first position for connecting the inflow port 13 and the first outflow port 11 of the main body 5 and a second position for connecting the inflow port 13 and the second outflow port 12. The position can be changed to. When the flow path switching member 35 is arranged at the first position, the drainage flowing in from the inflow port 13 flows out from the first outflow port 11. When the flow path switching member 35 is arranged at the second position, the drainage flowing in from the inflow port 13 flows out from the second outflow port 12.

11 to 13 show a state in which the flow path switching member 35 is arranged at the first position. When the flow path switching member 35 is arranged at the first position, as shown in FIG. 14, the shaft portion 152 of the handle 150 is further fitted into the fitting hole 132 of the engagement hole 130 of the main body 5. .. The grip member 151 of the handle 150 is located at a position lower than the upper end of the inclined portion 155 of the support member 160.

When removing the flow path switching member 35 from the main body 5, the operator inserts an arm through the inspection port 19 (see FIG. 1), grasps the grip member 151 of the handle 150, and pulls it up. As a result, first, the gripping member 151 slides upward with respect to the support member 160. When the gripping member 151 slides upward, both the supporting members 160 move laterally (inward in the radial direction) so as to approach each other. As a result, the shaft portion 152 of both support members 160 is pulled out from the fitting hole 132 of the main body 5.

When the gripping member 151 slides further upward, the stepped surface 154c (see FIG. 15) of the protrusion 154 of the gripping member 151 comes into contact with the stepped surface 156c of the slide groove 156 of the support member 160. Then, the slide of the grip member 151 with respect to the support member 160 is restricted, and the support member 160 is lifted together with the grip member 151. At this time, the shaft portion 152 of the support member 160 is further pulled out from the fitting hole 132 of the main body 5. Further, the support member 160 is connected to the flow path switching member 35. Therefore, the flow path switching member 35 is also lifted together with the gripping member 151. The shaft portion 152 moves upward along the slide groove 131 of the engaging hole 130, and then is pulled out upward from the slide groove 131. In this way, the operator can take out the flow path switching member 35 from the first position by pulling the grip member 151 of the handle 150 upward.

After taking out the flow path switching member 35 from the main body 5, the operator holds the handle 150, and the shaft portion 152 of the handle 150 is the true of the engagement hole 130 of the third connecting portion 63 and the fourth connecting portion 64. The flow path switching member 35 is rotated horizontally by 120 degrees so that it is located above. Then, the handle 150 and the flow path switching member 35 are inserted downward with respect to the main body 5.

Similar to the first embodiment, when the handle 150 and the flow path switching member 35 are inserted into the main body 5, first, the lower end portion of the closing member 37 of the flow path switching member 35 hits the bottom wall portion 14 of the main body 5. Subsequently, the flow path member 38 slides downward with respect to the closing member 37. The shaft portion 152 of the handle 150 is inserted into the engaging holes 130 of the third connecting portion 63 and the fourth connecting portion 64 of the main body 5, and is guided downward along the slide groove 131.

When the flow path member 38 is placed on the bottom wall portion 14 of the main body 5, the shaft portion 152 of the handle 150 reaches the lower end portion of the slide groove 131 and faces the fitting hole 132 (see FIG. 16A). ). When the grip member 151 of the handle 150 is pushed further downward, the grip member 151 slides with respect to the support member 160. When the gripping member 151 slides downward, the support member 160 moves outward in the radial direction, and the shaft portion 152 fits into the fitting hole 132 (see FIG. 16B). As a result, the flow path switching member 35 is arranged at the second position.

When the shaft portion 152 is fitted into the fitting hole 132, as shown in FIG. 16B, the stepped surface 152c of the shaft portion 152 is fitted with the third connecting portion 63 and the fourth connecting portion 64. It comes into contact with the peripheral portion of the hole 132. As a result, the outward movement of the shaft portion 152 in the radial direction is restricted. Further, since the distance between the two support members 160 is prevented from becoming large, the grip member 151 is prevented from falling off from the support member 160 downward. In the present embodiment, the shaft portion 152 constitutes the stepped surface 152c by having two portions 152a and 152b having different vertical widths, but the stepped surface 152c is formed by having two portions having different left and right widths. It is also possible to configure. Further, by making the tip surface of the shaft portion 152 come into contact with a part of the main body 5, it is possible to restrict the outward movement of the shaft portion 152 in the radial direction and prevent the gripping member 151 from falling off. The stepped surface 152c of the shaft portion 152 is not always necessary, and the width of the shaft portion 152 may be constant.

If the flow path switching member 35 is not correctly arranged at the second position, the positions of the shaft portion 152 and the fitting hole 132 will be displaced, so that the shaft portion 152 will not fit into the fitting hole 132. If the shaft portion 152 is not fitted in the fitting hole 132, the gripping member 151 does not slide downward with respect to the support member 160. Conversely, when the gripping member 151 slides with respect to the support member 160, the flow path switching member 35 is correctly arranged at the second position. Further, if the shaft portion 152 is fitted in the fitting hole 132, the flow path switching member 35 is correctly arranged at the second position.

According to the present embodiment, the flow path is based on whether the grip member 151 slides downward with respect to the support member 160 or whether the shaft portion 152 is fitted into the fitting hole 132. It can be confirmed whether or not the switching member 35 is correctly arranged at the second position. As shown in FIG. 14, when the gripping member 151 slides downward with respect to the support member 160, a part of the inner surface of the inclined portion 155 of the support member 160 (the portion provided with cross hatching in FIG. 14) is exposed. Then, it becomes visible from the inspection port 19. Further, as shown by cross-hatching in FIG. 16B, when the shaft portion 152 is fitted into the fitting hole 132, the tip of the shaft portion 152 is further outside the connecting portions 63 and 64 of the main body 5. The portion 152k1 becomes visible from the inspection port 19. Further, between the connecting portion 43 of the flow path switching member 35 and the connecting portions 63 and 64 of the main body 5, the portion 152k2 in the vicinity of the stepped surface 152c of the shaft portion 152 becomes visible from the inspection port 19. In the present embodiment, it is confirmed that the flow path switching member 35 is correctly arranged in a part of the inner surface of the inclined portion 155 of the support member 160, a part of 155k, a part of the shaft part 152 of 152k1, and another part of 152k2. It functions as a confirmation unit for doing so.

After arranging the flow path switching member 35 in the second position, the operator visually observed at least one of the above portions 155k, 152k1, and 152k2, so that the flow path switching member 35 was correctly arranged in the second position. Make sure that. Then, after the confirmation is completed, the inspection port 19 is covered with the lid 16.

As described above, the position of the flow path switching member 35 can be changed from the first position to the second position, and the flow path of the drainage basin 1 can be switched.

Although the description is omitted, the work of changing the position of the flow path switching member 35 from the second position to the first position can be performed in the same manner. However, in this case, the shaft portion 152 of the handle 150 is pulled out from the engaging holes 130 of the third connecting portion 63 and the fourth connecting portion 64 of the main body 5, and the first connecting portion 61 and the second connecting portion 62 are engaged. It will be inserted into the joint hole 130.

As described above, also in the present embodiment, the operator can change the position of the flow path switching member 35 by using the handle 150, and can switch the flow path. Further, the operator can correctly arrange the flow path switching member 35 in the first position and correctly in the second position only by visually observing a part 155k, 152k1 or 152k2 of the handle 150 through the inspection port 19. You can easily confirm both that they have been placed.

The colors of the above-mentioned parts 155k, 152k1 and 152k2 of the handle 150 may be the same as the colors of the other parts, but are preferably different from the colors of the other parts in order to enhance the distinctiveness. The colors of the above-mentioned portions 155k, 152k1, 152k2 and other parts are not particularly limited, but for example, the colors of the above-mentioned parts 155k, 152k1, 152k2 are yellow and the colors of the other parts are gray to enhance the distinctiveness. be able to.

The configuration of the handle 150 is not particularly limited. In the present embodiment, as schematically shown in FIG. 17A, the shaft portion 152 of the support member 160 is provided at the lower end portion of the inclined portion 155, but as shown in FIG. 17B, the shaft portion 152 is provided. The portion 152 may be provided at the upper end portion of the inclined portion 155. Alternatively, the shaft portion 152 may be provided in the middle of the inclined portion 155.

(Other embodiments)
Although the two embodiments of the present invention have been described in detail above, the above-mentioned first embodiment and the second embodiment are merely examples, and various other embodiments are possible. Next, examples of other embodiments will be briefly described.

The handle 50 according to the first embodiment is configured to be rotatable, and the handle 150 according to the second embodiment is configured to be slidable. However, the mode of movement of the handle with respect to the flow path switching member 35 is not limited at all. For example, as shown in FIG. 18, a bendable handle 250 may be used. The handle 250 includes a first grip member 251A, a second grip member 251B, and a hinge 251C that rotatably connects the root portion of the first grip member 251A and the root portion of the second grip member 251B to each other. ing. A first shaft portion 252A is provided at the tip of the first grip member 251A, and a second shaft portion 252B is provided at the tip of the second grip member 251B. The first shaft portion 252A and the second shaft portion 252B penetrate through the through hole 45 of the connecting portion 43 of the flow path switching member 35 and are connected to the connecting portion 43. The operator can remove the flow path switching member 35 from the main body 5 together with the handle 250, and can insert the flow path switching member 35 into the main body 5 together with the handle 250.

When the operator is lifting the handle 250, as shown in FIG. 18A, the first gripping member 251A and the second gripping member 251B are in a bent state. The first gripping member 251A and the second gripping member 251B are configured so as not to bend below a predetermined angle. Therefore, the flow path switching member 35 does not fall off from the handle 250. When the handle 250 and the flow path switching member 35 are further inserted into the main body 5 and the flow path switching member 35 is arranged at the first position or the second position, the first shaft portion 252A and the second shaft portion 252B of the handle 250 are moved. It faces the engagement hole 230 of the connecting portion 60 of the main body 5. When the handle 250 is pushed downward in this state, the first gripping member 251A and the second gripping member 251B are expanded as shown in FIG. 18B, and the first shaft portion 252A and the second shaft portion 252B are engaged with the engaging holes. It fits into 230. Therefore, by visually observing whether or not the first gripping member 251A and the second gripping member 251B are in the expanded state (here, the straight state), the flow path switching member 35 is correctly set to the first position or the second position. It can be confirmed that it is arranged.

Also in this embodiment, any part of the handle 250 that is visible from the inspection port 19 when the flow path switching member 35 is correctly arranged at the first position or the second position is used as the confirmation unit. Can be done. For example, of the upper surfaces of the first shaft portion 252A and the second shaft portion 252B, the portion between the connecting portion 43 of the flow path switching member 35 and the connecting portion 60 of the main body 5 can be used as a confirmation portion. Also in this embodiment, the confirmation portion may be colored differently from the other portions.

In each of the above embodiments, the method of coloring the confirmation portion of the handle is not limited at all. For example, a coloring material may be applied to the confirmation portion, or another colored member may be attached. A reflector may be attached to the confirmation portion. Further, the confirmation portion may have a pattern different from that of other portions. Further, instead of coloring the confirmation portion, the portion around the confirmation portion may be colored, and the colors of the confirmation portion and other portions may be different.

In the first embodiment, a through hole 45 through which the shaft portion 52 of the handle 50 penetrates is formed in the connecting portion 43 of the flow path switching member 35. The through hole 45 of the connecting portion 43 is an example of an engaging portion with which the shaft portion 52 is engaged. However, the engaging portion is not limited to the through hole 45. For example, as shown in FIG. 19, the shaft portion 52 has a tip portion 52B that engages with the engagement hole 30 of the main body 5, and a U-shaped connecting portion 52A that connects the tip portion 52B and the grip portion 51. You may have. In the embodiment shown in FIG. 19, recesses 45b are formed on both sides of the connecting portion 43 of the flow path switching member 35, and one end of the grip portion 51 and one end of the tip portion 52B of the shaft portion 52 are recessed 45b.
