Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency toilet structure which can be used as a flush toilet immediately in the event of a disaster such as an earthquake while being used as a flush toilet in normal times.

[0002]

2. Description of the Related Art In the event of a disaster such as an earthquake, water and sewer systems cannot be used, and flush toilets often cannot be used. In such a case, how to treat excrement as a physiological phenomenon is affected by the disaster. It will be a big problem later in life. Conventionally, for the treatment of such excrement, it is common to install and use temporary toilets used at construction sites and the like.

[0003] However, this temporary toilet has a limited storage capacity for excrement, so that it becomes full immediately and cannot respond to many victims for a relatively long period of time. It is also difficult to prepare a large number of temporary pumping toilets due to the budget for disaster prevention measures, etc., and in the event of a disaster or the like, the emergence of an emergency toilet structure that can immediately store a large amount of excrement has been demanded. .

[0004] Therefore, a large number of toilets can be easily installed in a short time in an emergency, and a large amount of excrement can be stored using a basement so that many victims can use the toilets. The toilet installation structure is disclosed in, for example,
38142. In this emergency toilet installation structure, one or more temporary toilets are stored in a basement, and the emergency toilets are taken out to the ground surface in an emergency, and the basement is used as a toilet tank.

[0005]

However, in this emergency toilet installation structure, a relatively large amount of excrement can be stored in the basement in an emergency, but in a normal time when a disaster does not occur, a temporary pumping toilet is required. However, there is a problem that it is difficult to use the temporary pumping toilet effectively because it is only stored in the basement.

In addition, since it is necessary to provide a dedicated basement for storing the temporary toilet, it is troublesome to select an installation place, and it is necessary to newly provide a dedicated basement, and it is necessary to raise and lower the temporary toilet. Since a complicated mechanism or the like for moving is required, the cost is greatly increased, and it is difficult to install a large number in the right place at the right place due to the budget and the like. As a result, there is a problem that it is difficult to take effective disaster prevention measures.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and an object of the invention described in claims 1 to 4 is that it can be used as a flush toilet in normal times and can be used immediately as a flush toilet in emergency. An object of the present invention is to provide a flush toilet which can be used effectively, and which can be applied to an existing flush toilet at low cost and can provide effective disaster prevention measures.

[0008]

[0009] With this configuration, the trap detachably attached to the lower end of the defecation hole of the flush toilet is attached to the lower end of the toilet while being positioned in the piping pit substantially immediately below the defecation hole. It is usually used as a flush toilet. Then, in an emergency, for example, when a disaster occurs, the trap is removed from the lower end of the defecation hole of the toilet, and the defecation hole is opened into the piping pit. As a result, the existing flush toilet can be used as a pumping toilet using the plumbing pit as a toilet tank in an emergency state, and a large amount of excrement can be stored.

According to a second aspect of the present invention, a toilet flange provided at a lower end of a toilet bowl is connected to a flange at an upper end of a straight connection pipe, and a flange at a lower end of the connection pipe is connected to an inlet side of a trap. It is characterized by being detachably connected to a trap flange provided. With this configuration, the connection pipe connected to the lower end of the toilet prevents the excrement from jumping into the defecation hole and the like, and for example, cleanliness of the toilet during use is maintained.

The invention according to claim 3 is characterized in that a long groove for connection is formed in the flange so as to open outward. With this configuration, the toilet and the trap, or the toilet and the connection pipe, the trap, and the like can be easily attached and detached by using the long groove, so that emergency response can be more easily performed.

Further, the invention according to claim 4 is characterized in that the internal hole of the connection pipe is formed as a substantially tapered hole. With such a configuration, the lower end of the toilet bowl defecation hole and the entrance side of the trap can be connected by a continuous hole having no step, and the excrement can be smoothly dropped into the trap or piping pit, Dirty toilets are reliably prevented.

The flange 15 of the connection pipe 14 is connected.
The connection pipe 14 and the sewage main pipe 31 are connected to the trap 20, the flexible pipe 29
And a pipe 32.

Next, a method of using the toilet 1 will be described. First, the toilet 1 having the plumbing pit 8 below the floor 4 like the toilet 1 is a disaster prevention base such as a school and gymnasium, a public gymnasium, a public community center and a community center, a city hall, a police station, a fire station, and the like. In many cases, it is provided in a public restroom in a park, a restroom on a highway, or the like. A trap 20 is detachably connected to the restroom 1 of such a facility via a connection pipe 14 in advance, and the inside of the pipe pit 8 is installed. The tool box 11 and the like are installed.

During normal times when no disaster occurs, the toilet 1 is used as a flush toilet, and excrement H (see FIG. 9) is discharged from the defecation holes 6a, 7a of the toilet bowls 6, 7 through the connection pipe 14, etc. Through the trap 20. At this time, since the internal hole 17 of the connecting pipe 14 is formed by the square hole 17a and the tapered hole 17b so as not to have a step, the excrement H slides down the internal hole 17 of the connecting pipe 14 smoothly, It is stored in the water W in the trap 20 (see FIGS. 3 and 7). Then, low tank 3
The excrement H in the trap 20 is discharged into the sewage main pipe 31 through the flexible pipe 29 and the pipe 32 by flowing the water W from 5 and 36, and is used as a normal flush toilet.

On the other hand, in an emergency when tap water becomes unusable due to a disaster such as an earthquake, the toilets 6 and 7 of the toilet 1 cannot be used as a flush type. Switch to a lavatory type toilet as shown. That is, the bolts 24 and nuts 25 connecting the connection pipe 14 and the trap 20 are removed by using the tool in the tool box 11 after entering the pipe pit 8 from the manhole 9, so that the flange at the lower end of the connection pipe 14 is removed. 16

2 is removed. In addition, the clamp pipe 30 provided on the other end of the flexible pipe 29 is loosened, and the flexible pipe 29 is removed from the pipe 32.

As a result, as shown in FIG. 9, the lower end of the connection pipe 14 is opened into the piping pit 8, and the flush toilet 1 can be used as the pumping toilet 1 using the piping pit 8 as a toilet tank. Can be. At this time, switching to the pumping toilet 1 can be performed in a very short time and easily by removing the bolt 24 and the nut 25.

When the toilets 6 and 7 are used in this state, the excrement H falls through the defecation holes 6a and 7a of the toilets 6 and 7 and the internal hole 17 of the connection pipe 14 and is stored in the pipe pit 8. Is done. Since the pipe pit 8 is set to have a relatively large capacity, a large amount of excrement H is stored in the pipe pit 8 as a toilet tank. By the way, toilet 1
When the excrement H is stored to some extent in the pipe pit 8 due to the use of the excrement H, the stored excrement H may jump due to the falling excrement H. The entry is prevented by the connection pipe 14 connected to the defecation holes 6a, 7a of the toilet bowls 6, 7.

FIG. 9 illustrates the case where the trap 20 and the flexible pipe 29 are completely removed in an emergency. For example, as shown by a two-dot chain line in FIG. 3 and FIG. The trap 22 is detached from the flange 16 at the lower end of the connecting pipe 14, and the trap 20 is tilted downward as shown by the arrow A by utilizing the flexibility of the flexible pipe 29, and is used as the pumping toilet 1 in an emergency. You can also.

Further, the connecting pipe 14 connected to the toilet flange 13 or the flange 38 of the connecting pipe 37.

It is of course possible to open the lower ends of the pipes a and 7a directly into the piping pit 8 and use the toilet 1 as a pumping type toilet.

As described above, in the toilet 1 of the above embodiment, the trap 20 connected to the defecation holes 6a, 7a of the flush toilets 6, 7 is provided with the pipe pit 8 provided below the toilet 1. Because it is located directly below the defecation holes 6a and 7a within the inside and is detachably connected to the lower end of the connection pipe 14 connected to the toilet flange 13 (or the flange 38), in the event of a disaster or other emergency , Trap 2
For example, by removing 0 from the flange 16 at the lower end of the connecting pipe 14, the lower end of the connecting pipe 14 can be opened into the piping pit 8, and the airtight pipe pit 8 can be used as a toilet-type toilet 1 with a toilet tub. Can be.

As a result, the toilet 1 normally used as a flush toilet can be used as a flush toilet in an emergency, and a large amount of excrement can be stored in the piping pit 8, so that a large number of victims can be used in an emergency. This makes it possible to use it for a long period of time and to use the existing flush toilet effectively.

Since the trap 20 is detachably connected to the flange 16 of the connection pipe 14 by bolts 24 and nuts 25, the tool in the tool box 11 arranged in the pipe pit 8 is used. As a result, the trap 20 can be easily removed from the connection pipe 14, and an emergency can be taken immediately. In particular, if the long groove 26 is provided in the flange 16 or the like of the connection portion, the trap 20 can be detached and attached without removing the bolt 24 and the nut 25, and the operation can be performed more easily and immediately.

Furthermore, since it is possible to cope with only a partial change in the mounting structure of the trap 20 in the piping pit 8 of the existing flush toilet 1, public facilities designated as evacuation shelters can be handled. It can be easily installed in the toilet 1 or the like, so that there is no trouble in selecting an installation location. In addition, since there is no need to set up a dedicated basement or a temporary pumping toilet raising and lowering mechanism as in the conventional case, it is possible to respond cheaply and install it in many existing toilets 1 with a low budget, which is effective. Disaster prevention measures can be taken.

Further, the inner hole 17 of the connecting pipe 14
Square hole 17a and tapered hole 17b so as not to have a step.
, The excrement H can be smoothly dropped, and the toilet bowls 6 and 7 are prevented from being stained by the attachment of the excrement H. In addition, since the connection pipe 14 having a predetermined length is connected to the toilet flange 13 (or flange 38) at the lower end of the toilets 6 and 7, the pipe pit 8 in the pipe pit 8 when the pipe pit 8 is used as a toilet tub is used. Defecation holes 6a, 7a for excrement H
It is possible to prevent the inside from jumping up, maintain the cleanliness of the toilet 1 itself, and use the toilet 1 with confidence.

In the above embodiment, the trap 2
Although the connection pipes 14 and 37 and the toilet flange 13 are detachably connected by the bolts 24 and the nuts 25, for example, each connection portion may be provided with an openable and closable hook, and may be attached and detached by opening and closing the hook. Then, a detachable mechanism having an appropriate structure such as a structure in which the flange of the connection portion is slidably fitted can be adopted.

In the above embodiment, the case where two Japanese-style toilets 6 and one Western-style stool 7 are installed in the toilet 1 has been described. However, the types and number of the toilets 6 and 7 are as follows. It can be changed as appropriate. Furthermore, the length of the connection pipe 14, the shapes of the flanges 15, 16 and the internal holes 17, the shape of the trap 20, and the like in the above embodiment are also examples, and can be variously changed without departing from the gist of the present invention. Needless to say.
