Description

The present invention relates to a simple toilet piping system, a piping method in the simple toilet piping system, and a simple toilet used in the simple toilet piping system.

For example, various types of simple toilets have been proposed which are installed in evacuation shelters used in the event of a landslide caused by an earthquake or heavy rain, or the disruption of a large traffic network or an accident.

For example, in Patent Document 1, a cover plate that can be laid on the upper surface of the manhole opening of the sewer and has a through hole for dropping sewage into the sewer, and for hiding a toilet user standing on the outer peripheral side of the cover plate A toilet for disaster is disclosed, which is composed of an enclosure.

Further, in Patent Document 2, a base plate having a larger area than a manhole and having a feces hole formed in a central portion is provided, a lower part of a main frame is rotatably connected to the base plate, and a feces chute is formed. There is disclosed a toilet seat device for manhole in which the lower part of the seat is fitted in the toilet hole.

Japanese Patent No. 2652484 JP, 2008-161512, A

However, in the configurations of the above Patent Documents 1 and 2, since the toilet installation position is limited to just above the manhole, the center of the road, the front of the entrance of the building, or a narrow place where it is difficult for people to enter It was difficult to use manholes in positions that are not suitable for installing toilets such as. Further, as described above, in the structure in which the simple toilet is directly connected to the manhole cover, the structure is such that the inside can be directly viewed from the toilet seat, and therefore there is a problem that the user feels uncomfortable when dirt is seen. is there. In addition, when used by a child, there is a fear that the child may fall into a manhole.

Therefore, an object of the present invention is to provide a simple toilet piping system having a high degree of freedom in installation position while utilizing existing piping, a piping method in the simple toilet piping system, and a simple toilet.

The present invention is a simple toilet piping system comprising a simple toilet, an existing pipe, and a connection pipe portion that guides the waste received by the simple toilet to the existing pipe, wherein the simple toilet is It has a main body frame in which a toilet seat portion is disposed, and a leg portion frame provided below the main body frame, and in the toilet seat portion, a waste discharge port that opens downward is formed, On the lower side of the waste discharge port, the upstream pipe end portion of the connection pipe portion is connected, and the downstream pipe end portion of the connection pipe portion is connected to the existing pipe, The connection pipe part includes a flexible pipe part, which is a simple toilet piping system.

In such a configuration, since the existing pipe is used as the discharge destination of the filth, even a non-specialized person can easily install the simple toilet. Since the connecting pipe portion includes the flexible pipe portion, the positions of the upstream pipe end portion and the downstream pipe end portion of the flexible pipe portion are strictly determined based on the existing pipe. No need. For this reason, there is an advantage that the installation position is flexible when the simple toilet is installed. Further, even after the simple toilet is installed, it is easy to change the position of the simple toilet.

Further, it is preferable that at least a bottom portion of the inner peripheral surface of the flexible pipe portion in the connecting pipe portion is configured only by a downward inclined surface which inclines downward toward the downstream side and a horizontal plane.

With this configuration, the flexible pipe portion of the connecting pipe portion does not have a portion where dirt is accumulated. If at least the bottom portion of the inner peripheral surface of the flexible tube portion is formed with a surface that is inclined upward toward the downstream side, dirt will accumulate there, causing odor and the like to occur. ..

Further, it is desirable that the pipe axes at the upstream pipe end and the downstream pipe end of the connecting pipe portion both extend in the vertical direction and are arranged at positions eccentric to each other.

In such a configuration, since the pipe axes of both pipe end portions of the connecting pipe portion are eccentric (eccentric), it becomes difficult for the user side to directly visually recognize the inside of the pipe beyond the waste discharge port. Therefore, it becomes difficult to see the dirt and the discomfort given to the user can be reduced.

Furthermore, it is preferable that the main body frame has a folding structure that allows the main body frame to be folded.

With such a configuration, since the simple toilet is foldable, it is possible to save space during storage.

The leg frame is projected downward from the main body frame, and has a length adjusting structure capable of adjusting a protruding length with respect to the main body frame. It is desirable that the height of the toilet seat from the floor can be adjusted by adjusting the protruding length of the toilet seat.

With such a configuration, since the height of the simple toilet is adjustable, it is possible to flexibly respond to the difference in the physical constitution of the user. Further, even if the height of the toilet seat is adjusted with the waste discharge port and the connecting pipe being connected, the flexible pipe of the connecting pipe can flexibly follow.

Further, the existing pipe is connected to a standing pipe having an inspection port to which a lid frame to which a lid is detachably attached is attached, and dirt collected in the simple toilet is inserted through the frame of the lid frame. And a new attachment member different from the lid is attached to the lid frame, and the new attachment member has a hollow portion formed in a penetrating shape. A main body and a fitting that is arranged on the outer peripheral surface of the new mounting member main body and that fits to a portion of the inner peripheral surface of the lid frame to which the lid is mounted, with the new mounting member mounted on the lid frame. And a hollow portion of the new mounting member is opened on the upstream side and the downstream side, respectively, in the state where the new mounting member is mounted on the lid frame, A configuration is proposed in which the connection pipe portion on the side of the simple toilet is connected to the opening.

In such a configuration, the waste discharged from the simple toilet is guided into the existing pipe through the new attachment member. Therefore, it is possible to perform the waste treatment of the simple toilet without excavating the ground around the existing pipe again, and it is possible to significantly reduce the construction time and cost. Of course, if the simple toilet is to be removed, it is sufficient to remove the unnecessary new attachment member and attach a lid without holes to the inspection port, so the original The structure can be easily restored.

Furthermore, the present invention is a piping method for constructing the simple toilet piping system, comprising a step of removing a lid from the lid frame, and a step of attaching the new attachment member to the lid frame from which the lid has been removed, And a step of connecting the connecting pipe portion to the new mounting member, which is a piping method in a simple toilet piping system.

With such a configuration, even if a simple toilet is to be installed urgently, the simple toilet piping system can be quickly installed.

Furthermore, the present invention is the simple toilet used in the simple toilet piping system, wherein the waste discharge port is located above the lower end of the leg frame. ..

In such a configuration, the connecting pipe portion can be arranged in the gap formed between the waste discharge port and the floor surface. As a result, the simple toilet piping system can be provided without burying the connecting pipe portion in the ground, and the simple toilet can be quickly installed without relying on a specialist. In addition, the gap also functions as a construction space when constructing the pipeline, which improves workability.

Further, the main frame 61 is provided with a pair of left and right rear leg frames 71, 71 pivotally supported by the main frame 61. The other ends of the pair of left and right link pipes 67, 67 and the upper ends of the rear leg frames 71, 71 are rotatably connected via a pair of left and right support plates 73, 73. The pair of left and right rear leg frames 71, 71 are connected via a rear leg connecting bar 75. In this embodiment, two rear leg connecting bars 75 are provided.

Further, leg frames 77 project downward from the lower end of the main frame 61 and the lower ends of the rear leg frames 71, respectively.

The leg frame 77 has a length adjusting structure 80 capable of adjusting the downward projecting length with respect to the main frame 61 and the rear leg frame 71. More specifically, the lower ends of the main frame 61 and the rear leg frame 71 are nested inside the leg frame 77. Further, the leg frame 77 is provided with a plurality (three) of length adjusting holes 82, and the length adjusting pin 81 is inserted into any of the length adjusting holes 82, so that the leg frame 77 is predetermined. It can be fixed at the length of. The length adjusting pin 81 and the length adjusting hole 82 form a length adjusting structure 80.

The toilet seat 90 arranged on the main body frame 60 has a hollow disk-shaped base 91 fixed to the support plate 73 of the main body frame 60.

Further, the toilet seat 90 has a funnel-shaped waste receiving portion 95 which is a separate member different from the base portion 91 having a portion extending downward from the waste discharge port 97. The outer peripheral edge of the waste receiving portion 95 is supported by the base portion 91, is detachable from the base portion 91, and has a waste outlet 97 (see FIG. 1, etc.) that opens downward. ing.

Since the waste receiving portion 95 has a funnel shape, the waste receiving portion 95 can be stacked while being detached from the base portion 91, and a plurality of waste receiving portions 95 can be compactly stored. Further, it is possible to remove the dirt receiving portion 95 from the simple toilet 50 and then individually wash the dirt receiving portion 95. The waste receiving portion 95 may be integrally formed with the base portion 91. When the waste receiving portion 95 and the base portion 91 are integrated, the management when the simple toilet 50 is folded and stored is simplified.

The sewage discharge port 97 (that is, the lower end of the sewage receiving portion 95) has a size and shape that is located above the lower end of the leg frame 77.

Further, as shown in FIG. 1, a hollow disc-shaped seat portion 99 on which a user sits is arranged above the outer peripheral edge portion of the waste receiving portion 95. The rear portion of the seat portion 99 is pivotally supported by the base portion 91, and the seat portion 99 is rotatable upward.

A folding structure 110 is provided on the body frame 60. The folding structure 110 will be described in detail below.

Lock pin insertion holes 111, which open toward the rear side, are provided on the upper portions of the pair of left and right rear leg frames 71, 71, respectively. Further, a pair of left and right lock pins 112, 112 inserted through the lock pin insertion holes 111 are connected to a lower rear portion of the base portion 91 of the toilet seat 90 via a lock belt 113. The lock pin 112 is biased forward by a spring and inserted into the lock pin insertion hole 111 (see FIG. 2).

Then, when the lock belt 113 is pulled backward, the lock pin 112 is pulled out from the lock pin insertion hole 111, and the support plate 73 to which the toilet seat 90 is fixed, the main frame 61, the link pipe 67, and the rear leg frame. 71 and 71 are linked to each other and rotate about the left-right direction, and as shown in FIG. 3, they can be folded compactly while maintaining the standing state.

When the simple toilet 50 is folded, it can be stored very compactly by removing the waste receiving portion 95 and folding it. At this time, since the waste receiving portion 95 does not interfere with the main body frame 60, it is possible to store as many simple toilets 50 as possible in a limited space.

In this embodiment, the folding structure 110 is configured by the link structure of the support plate 73, the main frame 61, the link pipe 67, and the rear leg frame 71, the lock pin insertion hole 111, the lock pin 112, and the lock belt 113. Has been done.

In the above-described simple toilet 50, for example, a simple toilet piping system can be constructed by connecting an upstream pipe end of a connecting pipe portion connected to an existing pipe.

As shown in FIG. 4( a ), when the simple toilet 50 is installed, a simple toilet piping system 1</b>A that introduces the waste discharged from the simple toilet 50 into the existing pipe 5 buried underground is constructed. It is suggested to do.

Hereinafter, the simple toilet piping system 1A will be described.
As shown in FIG. 4A, a connection pipe portion 10 that guides wastewater containing waste to the existing pipe 5 is connected to the lower side of the waste discharge port 97 provided in the simple toilet 50.

That is, the upstream pipe end portion 11 of the connecting pipe portion 10 is connected to the lower side of the waste discharge port 97. The upstream pipe end 11 is open upward, and is provided with a flexible pipe portion 11a that is vertically expandable and contractible and can be bent laterally. The flexible tube portion 11a is preferably formed of a bellows tube, but may be formed of a known rubber hose or the like.

Here, in the simple toilet 50, the position of the leg frame 77 (see FIG. 1) can be adjusted to adjust the height of the toilet seat. However, when the height of the toilet seat is changed in this way, the flexible pipe portion 11a can expand and contract following the vertical movement of the waste discharge port 97. Therefore, it is not necessary to correct the position of the pipe of the connecting pipe portion 10 every time the height of the simple toilet 50 is adjusted.

The bottom of the inner peripheral surface of the flexible tube portion 11a is composed only of a downward inclined surface that inclines downward toward the downstream side and a horizontal plane. As a result, it is possible to prevent filth from accumulating in the flexible tube portion 11a.

By the way, the opening diameter of the upstream pipe end 11 is set to be larger than the opening diameter of the waste discharge port 97 of the simple toilet 50, and the waste discharge port 97 (that is, the waste receiving portion 95) is provided in the upstream pipe end 11. The lower end of the pipe is inserted, and the tape is closed by a tape (not shown) so that the odor in the pipe does not leak outside. As described above, since the waste discharge port 97 is located above the lower end of the leg frame 77, it is possible to arrange the connecting pipe portion 10 in the gap formed between the waste discharge port 97 and the floor surface. Therefore, it is not necessary to bury the connecting pipe portion 10 in the ground.

An elbow pipe 14 for guiding waste to the existing pipe 5 is connected to the flexible pipe portion 11a, and an upstream straight pipe 16 is further connected to the elbow pipe 14.

The upstream pipe end portion 11 including the flexible pipe portion 11a, the elbow pipe 14, and the upstream straight pipe 16 constitute the connecting pipe portion 10. The details of the connection structure of the upstream straight pipe 16 and the existing pipe 5 will be described later.

In the above-described configuration, since the existing pipe 5 is used as the waste discharge destination, the simple toilet 50 can be easily installed even by a non-specialist. Further, in the above-mentioned configuration, the pipe axes at the upstream pipe end and the downstream pipe end of the connecting pipe portion 10 are both arranged in the vertical direction and eccentric to each other. For this reason, it becomes difficult for the user side to directly visually recognize the inside of the pipe beyond the waste discharge port 97. Therefore, it becomes difficult to see the dirt and the discomfort given to the user can be reduced.

Further, the simple toilet piping system 1B may be constructed in a mode as shown in FIG. 4B without using the elbow pipe 14 and the upstream straight pipe 16. In such a configuration, both the pipe axis of the upstream pipe end and the pipe shaft of the downstream pipe end of the flexible pipe portion 11a are along the vertical direction, and Since the bottom part of the peripheral surface is configured by the downward inclined surface, the dirt flows down gently without staying in the flexible tube portion 11a.

Further, in the simple toilet piping system 1B, when the height of the toilet seat 90 is adjusted, the entire flexible pipe 11a is freely curved to follow the change in the height position of the waste discharge port 97. be able to.

Next, the simple toilet piping system 1C will be described with reference to FIG. Descriptions of contents similar to those of the above-described simple toilet piping systems 1A and 1B are appropriately omitted.

The connecting pipe portion 10 is connected to the lower side of the waste discharge port 97 provided in the simple toilet 50.

That is, the upstream pipe end portion 11 of the connecting pipe portion 10 is connected to the lower side of the waste discharge port 97. The upstream pipe end portion 11 is provided with a flexible pipe portion 11a and an elbow pipe 11b connected to the lower side of the flexible pipe portion 11a. The flexible tube portion 11a can be configured by a known rubber hose, a bellows tube, or the like.

Further, the elbow pipe 11b is connected to a straight pipe 13 for guiding the waste to the existing pipe 5. An elbow pipe 14 is connected downward to the other end of the straight pipe 13, and an upstream straight pipe 16 is further connected to the elbow pipe 14.

The upstream pipe end portion 11 including the flexible pipe portion 11a and the elbow pipe 11b, the straight pipe 13, the elbow pipe 14, and the upstream straight pipe 16 constitute the connecting pipe portion 10.

On the other hand, as shown in FIGS. 5 and 6, the standing pipe 8 is connected to the existing pipe 5, and the inspection port 7A is formed at the upper end of the standing pipe 8. Further, a lid frame 20A is attached to the inspection port 7A, and a joint 30A as a new attachment member mainly composed of a tubular body is attached to the lid frame 20A. As will be described later, the lid frame 20A originally had a lid 6 (see FIG. 8a) that removably attached to close the opening 21A of the lid frame 20A.

Further, an annular packing 15 as a seal member is arranged in an elastically contracted state between the inner peripheral surface of the lid frame 20A and the joint 30A. Thus, it is possible to prevent the odor in the existing pipe 5 from leaking to the outside from between the lid frame 20A and the joint 30A. Further, if the internal structure of the existing lid frame 20A and the shape of the fitting portion of the newly installed joint 30A do not match, it is possible to close a small gap between them with the packing 15.

The elbow pipe 14 and the upstream pipe end of the joint 30A are connected by the upstream straight pipe 16.

Further, the downstream straight pipe 17 arranged in the standing pipe 8 is connected to the downstream pipe end of the joint 30A. The lower end of the downstream straight pipe 17 is arranged near the lower end of the standing pipe 8. The downstream straight pipe 17 constitutes a downstream pipe.

With the above-mentioned configuration, the waste discharged from the simple toilet 50 is guided into the joint 30A through the connecting pipe portion 10 and introduced into the existing pipe 5 from the downstream pipe opening of the downstream straight pipe 17. The pipe 5 includes an existing drainage pipe to which the standing pipe 8 is connected, and an existing pipe material connected to the drainage pipe.

Next, the joint 30A will be described in more detail.
As shown in FIGS. 7(a), (b), (c), and (d), the joint 30A includes a joint main body 35 as a new mounting member main body having a tubular hollow portion formed in a penetrating shape, and a joint main body. The upper end of the joint body 35 includes a flange portion 31 as a fitting portion formed on the outer peripheral surface of the joint body 35.

On the inner peripheral surface of the joint body 35, a step portion 38 is provided which projects toward the axis of the hollow portion of the joint body 35 and is circumferentially formed around the axis. Then, as shown in FIG. 6, the lower end 16a of the upstream straight pipe 16 is abutted against the upper side of the step portion 38 (on the side of the flange portion 31). On the other hand, the upper end 17a of the downstream straight pipe 17 is abutted against the lower side of the step portion 38. When the downstream straight pipe 17 is provided in this way, it is possible to suppress that filth is scattered on the inner wall surface of the standing pipe 8 and stains the inner wall surface, and the sanitary environment of the inspection port 7A is suppressed. Is preferably maintained.

Further, in the joint body 35, an upstream taper portion 41 having an inner diameter reduced toward the step portion 38 is provided on the inner peripheral surface on the upstream side of the step portion 38. On the other hand, on the inner peripheral surface on the downstream side of the step portion 38, a downstream taper portion 42 having an inner diameter reduced toward the step portion 38 is provided. With this configuration, the pipes can be easily connected.

An upper surface 36, which is an outer peripheral surface of the flange portion 31 and serves as an upper end surface of the joint 30A, has a flat shape, and a groove-shaped cutting line portion 37 is provided on the upper surface 36 in a circumferential shape around the axis. Has been. The cutting line portion 37 will be described later.

Further, the lower outer peripheral surface 32 of the flange portion 31 has a tapered shape in which the diameter increases toward the upper side so as to correspond to the shape of the portion of the inner peripheral surface 22A of the lid frame 20A to which the lid 6 is attached.

Next, a construction procedure of the simple toilet piping system 1A will be described with reference to FIGS. 8 and 9.
Before the simple toilet 50 is installed, the inspection port 7A of the existing pipe 5 is completely shielded by the lid 6 detachably attached to the lid frame 20A, as shown in FIG. 8A. Then, the lid 6 is removed from the lid frame 20A with the new installation of the simple toilet 50 (step 1).

Next, as shown in FIG. 8B, the downstream straight pipe 17 is connected to the opening at the lower end of the joint 30A corresponding to the lid frame 20A (step 2). At this time, the downstream straight pipe 17 is inserted into the joint 30A until the upper end 17a of the downstream straight pipe 17 hits the step 38 of the joint 30A. The joint 30A and the downstream straight pipe 17 may be joined with an adhesive or the like.

Then, as shown in FIG. 9A, the joint 30A to which the downstream straight pipe 17 is connected is attached to the lid frame 20A from which the lid 6 is removed (step 3). At this time, the packing 15 is attached to the joint body 35 of the joint 30A in advance. The packing 15 can eliminate a gap between the outer peripheral surface of the joint 30A and the inner peripheral surface of the lid frame 20A, and can prevent the odor in the pipe 5 from leaking to the outside. Further, since the portion of the inner peripheral surface 22A of the lid frame 20A to which the lid 6 is attached and the lower outer peripheral surface 32 of the joint 30A have respective shapes corresponding to each other, it is possible to fit them properly without rattling. it can. However, the packing 15 does not need to be attached on site, and may be attached to the joint 30A in advance at a factory or the like, for example.

Further, as shown in FIG. 9B, the upstream straight pipe 16 to which the elbow pipe 14 is connected is connected to the opening at the upper end of the joint 30A (step 4). At this time, the upstream straight pipe 16 is inserted into the joint 30A until the lower end 16a of the upstream straight pipe 16 comes into contact with the step portion 38 of the joint 30A. In this way, since the upstream straight pipe 16 and the downstream straight pipe 17 are prevented from directly abutting each other by the step portion 38, the upstream straight pipe 16 or the downstream straight pipe 17 is the other straight pipe. It will not be extruded by and fall off from the joint 30A. The joint 30A and the upstream straight pipe 16 may be joined with an adhesive or the like. Further, the elbow pipe 14 may be connected to the upstream straight pipe 16 after the upstream straight pipe 16 is connected to the joint 30A.

Then, the steps 1 to 4 described above construct the simple toilet piping system 1C as shown in FIG.

The drainage piping method including the steps 1 to 4 described so far does not require a step of excavating the ground around the inspection port 7A to install the simple toilet 50, so that the simple toilet 50 can be quickly installed. It can be ready for use. Moreover, since it is possible to install the simple toilet 50 at a position away from the inspection port 7A, the degree of freedom in the installation position of the simple toilet 50 is significantly improved. Further, as shown in FIG. 10, by bending the flexible tube portion 11a, the position of the simple toilet 50 can be appropriately changed to a desired position around the inspection port 7A.

Further, even if the simple toilet 50 becomes unnecessary and the simple toilet piping system 1C is to be removed, there is no need to excavate the ground again, and after removing the unnecessary joint 30A and the like, the original lid is removed. If 6 is reattached, the original structure can be easily restored. The mounting order of the pipe materials can be appropriately changed depending on the situation of the construction site. Moreover, when each pipe material is used, it can be cut into an appropriate length and used at the construction site according to the situation of the construction site. Alternatively, for example, the elbow pipe 14 and the joint 30A may be directly connected.

By the way, when constructing the simple toilet piping system 1C for discharging the waste from the simple toilet 50, the lid frame 20A attached to the inspection port 7A for introducing the waste is prepared. In some cases, the joint 30A cannot be used as it is. Hereinafter, the simple toilet piping system 1D that is going to be constructed by using the joint 30A on the lid frame 20B having a shape different from the lid frame 20A will be described.

As shown in FIG. 11, unlike the lid frame 20A, the lid frame 20B has a substantially vertical inner peripheral surface 22B.

In such a case, in the joint 30A, a tool such as a sander is used to cut off the outer peripheral edge portion of the flange portion 31 along the cutting line portion 37 (see FIG. 7a). Then, as shown in FIG. 7E, the lower outer peripheral surface 32 of the flange portion 31 is formed with the lower outer peripheral surface 33 corresponding to the inner peripheral surface 22B of the lid frame 20B. As described above, the joint 30A can change the outer diameter D1 (see FIG. 7d) of the flange portion 31 to the outer diameter D2 smaller than that by cutting the outer peripheral edge portion of the flange portion 31. Has become. With such a configuration, the joint 30A can be appropriately attached to the lid frame 20B to construct the simple toilet piping system 1D.

In addition, when constructing the simple toilet piping system 1D using the lid frame 20B, the step of cutting the outer peripheral edge portion from the flange portion 31 of the joint 30A may be performed before the joint 30A is attached to the lid frame 20B. Good.

By adopting such a configuration, for example, even if a lid frame 20B having an inner peripheral surface shape different from that of the lid frame 20A is adopted in the existing pipe 5 for introducing filth, it is suitable for a different kind of lid frame 20B. By cutting the outer peripheral edge portion of the flange portion 31 with the cutting line portion 37 formed in advance as a reference, the joint 30A that matches the inner peripheral surface shape of the lid frame 20B can be obtained. There is no need to prepare a joint. In particular, when the simple toilet 50 is installed, it may be urgent in some cases, and it is desirable to have a configuration that enables quick construction.

Further, in the embodiments described so far, the shape of the cutting line portion 37 is not limited to the groove shape, and an index indicating a portion to be cut may be displayed. Further, the outer shape of the flange portion 31 of the joint 30A is not limited to the disc shape, and may be an outer shape of another shape depending on the lid frames 20A and 20B. Further, a single cutting line portion 37 may be provided for the joint 30A, or a plurality of cutting line portions 37 may be provided.

Further, the arrangement position of the packing 15 is not limited to the position of the above configuration, and can be changed appropriately. Moreover, the pipe material which comprises simple toilet piping system 1A-1D is not specifically limited. In particular, the flexible tube portion 11a may be a member having flexibility so as to follow when the position of the simple toilet 50 is changed in the horizontal direction, and the height of the toilet seat 90 is changed. In this case, any member may be used as long as it has flexibility. Further, the lower end of the downstream straight pipe 17 is preferably arranged near the lower end of the existing pipe 5, but the present invention is not limited to this configuration. The existing pipe 5 may be a pipe that discharges waste water at normal times, and may be a pipe that requires construction by a specialist or the like. Therefore, not only the pipes buried in the ground but also the pipes provided under the floor indoors and the like are included, and in this sense, the simple toilet 50 according to the present invention can be used regardless of whether it is outdoors or indoors. .. For example, an indoor pipe is connected to the upstream side of the existing pipe 5 or an independent pipe or the like is connected, and when the simple toilet 50 according to the present invention is used, it has already been constructed. The pipe that corresponds to is the existing pipe.

Another joint 30B will be described with reference to FIG. It should be noted that the same components as those of the joint 30A described above are denoted by the same reference numerals and the description thereof will be simplified.

Unlike the joint 30A, the joint 30B is not provided with the cutting line portion 37. In the joint 30B, when it is clear that the lid frame 20A in which the flange portion 31 is fitted as it is is applied, the simple toilet piping system 1A can be quickly constructed.

The simple toilet piping systems 1A to 1D described above can of course be applied to drainage, rainwater drainage, or the like.

Further, although the joint 30A is illustrated as an example of the new attachment member, the plate-shaped lid may be used as the new attachment member. For example, a hole may be opened in the center of the lid, and the upstream straight pipe 16 may be connected to the hole. In this case, the outer peripheral portion of the lid may correspond to the fitting portion, and the cutting line portion 37 may be provided on the outer peripheral portion.

In the above embodiment, the size and shape of each part can be freely selected. For example, the length adjusting structure 80 and the folding structure 110 may have configurations other than the above. Further, the simple toilet 50 may have another configuration as long as it can be used by a user or the like by assembling it in a situation where a normally used toilet cannot be used. The shape of the waste receiving portion 95 is such that the waste receiving portion 97 is opened downward and is an opening for discharging the waste from the simple toilet 50 and is provided with a waste discharging port 97 formed on the opening surface on the user side. The funnel shape does not have to be a funnel shape, but it is preferable that the funnel shape is provided so as to face the toilet seat in order to use it as a toilet or to satisfy the point that it can be stacked. Further, the connecting pipe portion 10 may be a member that is newly attached when the simple toilet 50 is installed, or a member that is connected to the simple toilet 50 from the time of shipment in advance. Further, the leg frame 77 may have a pedestal shape provided below the main body frame 60, instead of the configuration described above.

As a matter of course, when the simple toilet 50 is installed, it is desirable to provide a peripheral wall, a partition or the like that surrounds it so that it cannot be visually recognized from the outside.

In addition, when the simple toilet 50 is connected to the existing pipe 5 by the connecting pipe portion 10, in addition to the configuration in which one connecting pipe portion 10 uses one inspection port 7A, 7B, a set having a plurality of inflow ports A configuration in which a plurality of connecting pipe portions 10 are connected to a plurality of inflow ports using a pipe, and filth is guided from a plurality of simple toilets 50 to an existing pipe 5 through one inspection port 7A, 7B, I don't mind. Since it is easy to arrange a plurality of the simple toilets 50 adjacent to each other in this manner, it is possible to effectively utilize them in a place where many people are supposed to use. Further, for example, an adult for which the toilet seat is set high and a child for which the toilet seat is set can be juxtaposed, so that the height of the toilet seat can be flexibly adjusted according to the difference in the physique of the user. ..
