Description

  The present invention relates to a temporary toilet installed at the time of a disaster.

In large-scale disasters involving the collapse of houses and fires, human waste disposal is a major problem. As temporary toilets and simple toilets that can be used by many victims, there are transportable simple toilets and so-called manhole toilets.
The portable toilet has a cabinet and a storage tank, and it is easy to secure the environment during use, but it has a limited storage capacity for human waste. The amount of human urine excreted by adults is set at 300 g / time and 1.6 liters / day. For this reason, in the evacuation area where a large number of victims gathered, it becomes necessary to frequently process the waste in the storage tank that is full. Also, because the cabinet is bulky, it is difficult to store at normal times.

In this respect, the manhole toilet uses an underground space (manhole) newly constructed in the sewage manhole or in a park or school yard, and has an extremely large human waste storage capacity, which is used by many victims at once. it can. Also, it is not as bulky as the transport cabinet, and there is little difficulty in normal storage.
Some manhole toilets use their iron lids directly as toilets, and others use separately prepared toilets on manholes to store manholes underground and use them for urine storage and discharge.

In Patent Document 1, the toilet 12 and the opening / closing lid 21 are provided on the manhole cover, and the manhole can be used as a toilet by turning it over.
Similarly, Patent Document 2 is a toilet system for disaster prevention that uses a manhole cover as a toilet.
Patent Documents 3 and 4 use a lid-like body prepared separately according to the lid, not the manhole lid itself, as a toilet.
Patent Document 5 is specially installed in a park or schoolyard as a manhole-type disaster toilet, and the defecation pipe 31 is considered to be connected to a sewer pipe or a pipe connected thereto. The toilet lid 13 is usually a manhole lid, but it becomes a toilet equipped with a handle 18 by being inverted.

  Patent Document 6 discloses a structure in which a Japanese-style toilet 16 or the like is attached to a rising tube 70 of a manhole 20 via a conversion joint (called an adapter). In this structure, a temporary toilet pipe 14 is laid in advance in an evacuation site such as a park and connected to a sewage pipe, and in the event of a disaster, a temporary toilet is installed on the rising pipe via a conversion joint.

JP-A-11-303113 JP 2004-183264 A JP-A-11-197058 Japanese Patent Application Laid-Open No. 11-89749 JP 2005-240510 A Japanese Patent Laid-Open No. 2004-337397

This invention improves the environment when using a conventional manhole toilet, and stores toilets and other materials on the spot, and can be pulled out and installed by any of the victims when necessary. The issue is to provide a toilet in the event of a high disaster.
In other words, conventional manhole toilets, which use iron lids directly, or connect toilets to sewage through adapters, have toilets connected directly to the sewage space. Odor is strong and easily diffused by the wind blowing from the side space. Furthermore, depending on the case, a deep underground space (sewage side space) enters the field of view, and fears are generated from the depth, or the inside can be seen and a strong discomfort is felt.

  In addition, in the type that uses the manhole iron cover as it is, it is not necessary to carry the toilet in the event of a disaster, but it is still necessary to carry attached items such as blindfolded tents and handrails from the storage location. This requires a person in charge at the time of the disaster, and procedures and procedures are required. The invention of the present application eliminates such a procedure and enables the disaster victims to install voluntarily.

The toilet will be a disaster toilet equipped with a storage box, a lid that closes it, and a toilet bowl.
The storage box has a cylindrical shape and can accommodate a toilet and close the lid.
The storage box is usually embedded in an underground space built in a park or schoolyard that serves as an evacuation site in the event of a disaster. In the event of a disaster, it is pulled out and used.
That is, the toilet bowl and other storage items are taken out from the storage box, and the empty storage box is turned upside down and covered between the hollows, and the toilet bowl is placed on the bottom (bottom side).
Since the storage box has a cylindrical shape, human waste from the toilet is directly stored between the hollows.
Since the storage box has a certain height, it can be a Western-style toilet together with a toilet seat placed thereon.

An upper edge engaging portion is provided on the upper edge of the storage box so as to hold the storage box between the hollows and cover the removed toilet in the underground space. In order to hold the toilet inside the storage box and to be placed on the storage box upside down, a lower edge engaging portion that protrudes inward is provided on the lower edge of the storage box.
The toilet includes a toilet seat, a tubular drop-in part, and a receiving part as a partition.
A toilet seat is attached to the upper end surface of the drop-in part, and a receiving part is attached in the middle of the drop-in part to block the inside up and down.
A base plate is pivotally attached to the receiving portion so that the front end side opens downward, and is always urged in the closing direction.

In another embodiment, the lid may be used as a Japanese style toilet. In this case, the lid has a toilet for a Japanese-style toilet, and is attached to the upper end surface of the drop-in part having a cylindrical shape separate from the toilet. The internal structure of the drop-in part such as the receiving part is the same as that of the toilet.
In order to urge the damper in the closing direction, a weight is attached to the base side of the damper plate, and an attractive force by a permanent magnet may be used.

In order to use the lid as a side table adjacent to the toilet, support legs attached to the four corners of the lid may be stored in a storage box.
In addition, in order to avoid a situation where the toilet set up in the manhole is blown up by sudden wind pressure from the sewage side, the surrounding wall that is above the receiving part as the partitioning part of the cylindrical drop part, or A pressure relief valve plate that can be opened only to the upper space side may be provided in a part of the receiving portion.

Since toilets and other necessary materials can be stored in a storage box and stored in advance in an evacuation area, any disaster victim can set up voluntarily and use it quickly.
Since a toilet bowl is mounted on a storage box that is upside down and used, the storage box has a height so that a Western-style toilet can be obtained.
Since the receiving section blocks communication between the underground space and the outside, the toilet user is less likely to suffer from the odor from the underground space. In addition, the underground space cannot be seen directly from the toilet, and discomfort can be reduced during the fear of the toilet user.

When a toilet mouth corresponding to a Japanese-style toilet is provided on the lid and attached to the upper end surface of the drop-in part having a cylindrical shape separate from the toilet, the lid can be used as a Japanese-style toilet together with the Western-style toilet using the toilet.
If the support legs can be attached to the four corners of the lid, the lid can be used as a table adjacent to the toilet. It is useful as a side table for temporary placement.

[First embodiment]
In FIG. 1, a toilet 1 at the time of a disaster includes a storage box 2, a toilet 3 and a lid 4.
In this embodiment, the storage box 2 is a square tube with a square cross section formed of a steel plate, and is fitted in an underground space 5 constructed in the ground such as a park or schoolyard as an evacuation site.
As shown in FIGS. 2 and 3, the storage box 2 has an upper edge engaging portion 6 projecting outward on the upper edge and a lower edge engaging portion 7 projecting inward on the lower edge. The upper edge engaging portion 6 can be engaged with the upper edge of the underground space 5 and is attached to a stepped portion of the iron frame 8 fixed to the upper end edge of the underground space 5 in a suspended state. The lower edge engaging portion 7 is used when a toilet 3 described later is attached in a suspended state or mounted on the storage box 2 with the top and bottom inverted.
In this embodiment, the dimensions of the storage box 2 are 370 mm in height, 645 mm on one side (outer periphery) of the upper edge engaging portion 6, 580 mm on one side (outer periphery) of the lower edge engaging portion 7, and One side (inner circumference) is 564 mm.

The toilet bowl 3 includes a toilet seat 9, a tubular drop part 10, and a receiving part 11 (FIGS. 2 and 3) configured inside the drop part 10. The toilet seat 9 is fixed to the upper end surface of the dropping part 10, and the receiving part 11 is attached to the inside of the dropping part 10 with its internal space blocked vertically.
The toilet seat 9 includes a base plate 12, a seat plate 13, a seat surface member 14, an arm guard 15, and a back guard 16.

  The base plate 12 is slightly smaller than the inner peripheral shape of the upper end surface of the storage box 2, but is in a larger range than the inner peripheral shape of the lower edge engaging portion 7 formed on the lower end surface of the storage box 2. It is a board. Therefore, the base plate 12 can be fitted into the interior of the storage box 2 through the opening at the upper end surface of the storage box 2 and can be engaged with the lower edge engaging portion 7 of the lower end surface. It can be said that the peripheral part of the base plate is an engaging part on the toilet bowl side. In this embodiment, the base plate 12 has positioning dowels 17 projecting downward on the lower surfaces of the four corners.

  The seat plate 13 is a reinforcing plate that supports the weight of the user, and the seat member 14 is attached thereto. The base plate 12 and the seat plate 13 are overlapped and fixed, and a toilet 18 is opened at the center. The toilet 18 communicates with the internal space of the dropping unit 10. The seat member 14 is attached so as to surround the toilet 18 for this purpose. An arm guard 15 and a back guard 16 are disposed so as to further surround the seat member 14. The base of the back guard 16 is fixed to the base plate 12, and the arm guard 15 is attached to the base of the back guard 16 so that the base of the recumbent can rotate in the vertical direction. Since the distal end side of the arm guard 15 is bent downward and its end is only in contact with the upper surface of the base plate 12, in this embodiment, the arm guard 15 can be pivoted upward and retracted in both the left and right directions. Yes (Figure 4). Since the arm guard 15 can be rotated upward, it is easy for a victim who has trouble with the movement of the body to sit on the seat member 14.

The drop-in part 10 includes a square tube 19 made of a steel plate that is slightly smaller than the storage box 2 and a receiving part 11 inside thereof. While the base plate 12 is fixed to the upper end surface of the square tube 19 by welding or screwing, a receiving portion 11 is attached to the internal space of the square tube 19, and the internal space is vertically moved by the receiving portion 11. It is divided.
As shown in FIGS. 2, 5, and 6, the receiving portion 11 includes a first swash plate 20, a second swash plate 21, a damper plate 22, and a magnet attachment member 23. These are all made of steel plates and are coated with Teflon (registered trademark) resin in order to make the upper surface smooth. Other smooth surface materials may be used.

The first swash plate 20 is arranged with a downward inclination of about 60 ° when viewed from the side, one end (front end) is fixed to the front wall 24 of the square tube 19, and the left and right sides are the left and right sides of the square tube 19. It is fixed to the side wall. The other end (rear end) of the first swash plate 20 is bent downward at a right angle to form a blocking edge 25.
The second swash plate 21 is arranged with a downward inclination of about 30 ° when viewed from the side, one end (rear end) is fixed to the rear wall 26 of the square tube 19, and the left and right sides are of the square tube 19. It is fixed to the left and right side walls.

The damper plate 22 has a front end portion rotatably attached to the lower surface side of the first swash plate 20, and a bent edge 27 that is slightly wider at a substantially right angle from the front portion to the lower side than the rotating shaft is formed. A fixed-side hinge is provided on the lower surface side of the first swash plate 20 and in front of the blocking edge 25, and a movable-side hinge is provided on the damper plate 22, and a hinge 28 is formed through the rotation shaft. The hinge 28 is rotatable.
A weight 29 is fixed to the front surface of the bent edge 27 of the damper plate 22.

The magnet attachment member 23 is a member fixed between the left and right side walls of the square tube 19 and includes a rising edge 30. The rising edge 30 is arranged to face the rear surface of the bent edge 27 when the damper plate 22 is in the normal position (FIGS. 2 and 5), and the permanent magnet 31 is fixed to the front surface.
The damper plate 22 rotatably attached to the lower surface of the first swash plate 20 has a rear end portion at the front end side of the second swash plate 21 in a normal state due to the weight of the weight 29 and the attractive force of the permanent magnet 31. Stops in contact with (lower edge).
In this embodiment, the joint action of the weight of the weight 29 and the attractive force of the permanent magnet 31 is such that the damper plate 22 can maintain a normal closed state at a weight of about 200 g (the amount of human urine per dwarf) or less. is there.

That is, the damper plate 22 imparts urging force in the closing direction by the weight 29 attached to the base side of the damper plate 22 and the attractive force by the permanent magnet 31. Further, the damper plate 22 is substantially parallel to the first swash plate 20 (downward tilt of 60 °) at the normal position (stop position).
5 and 6, reference numeral 32 denotes a cushion, which is attached to the lower edge of the second swash plate 21 in the left-right direction. The rear end of the damper plate 22 in the normal position is in close contact with the cushion 32. The receiving part 11 has the above-described structure, and when the damper plate 22 is in a normal position, the internal space of the dropping part 10 is blocked by the receiving part 11 and divided vertically.
In this embodiment, each dimension of the square tube 19 in the drop-in portion 10 is a cross-sectional rectangle having a height of 340 mm, a side view of 400 mm, and a front view of 290 mm, and the first swash plate 20 and the second swash plate 20 constituting the receiving portion 11. The width dimension of the front view of the swash plate 21 and the damper plate 22 is 176 mm. Further, the width dimension of the damper plate 22 is slightly smaller than those of the first and second swash plates 20 and 21 so as to be easily rotated. Note that the inside of the square tube 19 is narrowed so as to be in close contact with the side surfaces of the first and second swash plates 20 and 21.

  With the above structure, the toilet 3 is stored in the storage box 2 and stored in the underground space 5 as shown in FIGS. That is, the toilet bowl 3 including the arm guard 15 and the base plate 12 is smaller in overall plan view than the upper edge engaging portion 6 of the storage box 2, and the toilet bowl 3 is completely inside the storage box 2 from above the storage box 2. Can fit in. And the storage box 2 is provided with the lower edge engaging part 7, and since the periphery of the base plate 12 of the toilet seat 9 engages with this, the toilet box 3 is suspended in the lower edge engaging part 7, and the storage box 2 It is stored in.

  That is, the dropping part 10 of the toilet bowl 3 is suspended from the lower opening of the rectangular tubular storage box 2 to the underground space 5, and the toilet seat 9 of the toilet bowl 3 is located in the storage box 2. The upper opening of the storage box 2 is closed with a lid 4. The lid 4 is fixed to the upper surface of the upper edge engaging portion 6 of the storage box 2 with a bolt. The bolt is preferably one that can be loosened with a normal simple tool. In addition, when this disaster toilet 1 is embedded in a place where people and vehicles are trafficked, the head of the bolt that fixes the lid 4 to the storage box 2 is prevented from protruding from the upper surface of the lid 4.

When a disaster occurs, the disaster toilet 1 is constructed according to the following procedure. Remove the lid 4 and pull out the storage box 2 together with the toilet 3 from the underground space 5 (FIG. 1). Then, the toilet 3 is taken out from the storage box 2. Next, the storage box 2 is turned upside down, and the upper edge engaging portion 6 is placed on the opening of the underground space, that is, the iron frame 8 and fixed with a bolt (not shown) (FIG. 4). The toilet bowl 3 is placed on the lower edge engaging portion 7 that is the upper portion of the storage box 2 that is upside down. At this time, the drop-in part 10 is located inside the storage box 2, and the toilet seat 9 is positioned so that the peripheral part of the base plate 12 is exposed above the storage box 2 by being placed on the lower edge engaging part 7. (FIG. 4).
The base plate 12 is positioned and stably mounted by fitting dowels 17 provided at the four corners of the lower surface into dowel holes in the lower edge engaging portion 7.

The inside of the storage box 2 is sealed by the toilet bowl 3. That is, the upper opening of the storage box 2 turned upside down by the base plate 12 of the toilet seat 9 is closed, and the internal space of the drop-in part 10 leading to the toilet 18 is closed by the receiving part 11 (normal time).
The above-described operation of taking out the toilet 3 together with the storage box 2 from the underground space 5 and the operation of taking out the toilet 3 from the storage box 2 can be easily performed by anyone if two or three people cooperate. No special personnel or specialists are required to install 1.
In addition, all the necessary members are prepared on the spot, so that they can be used quickly.
Then, the surroundings are covered with a blindfold member (not shown) such as a tent to complete the disaster toilet 1. It is preferable that a blindfold member such as a tent is also folded and stored in the storage box 2. Moreover, it is preferable that the seat member is also prepared for a dwarf.

The toilet 1 at the time of a disaster is different in that it is similar to a normal Western-style toilet, but is not a flush type.
Human waste excreted by the use of the toilet is initially deposited on the tip of the damper plate 22 of the receiving portion 11. When the amount exceeds about 200 g by weight, the damper plate 22 is opened, and the human waste falls downward at once due to the lubrication action of urine and the surface of the damper plate 22 being coated with Teflon (registered trademark).
At this time, the damper plate 22 does not open gradually, but has an action of opening at once (FIG. 9) after holding up to the set weight by the attractive force of the permanent magnet 31 (FIG. 8). Therefore, human waste tends to fall. When the human waste falls, the damper plate 22 is pivoted upward by the action of the weight 29, and at the final stage in the closing direction, it is surely brought to the normal closed position by the attractive force of the permanent magnet 31. Is maintained. In this state, the rear end of the damper plate 22 is in close contact with the cushion 32 of the second swash plate 21.

The fallen human waste is stored at the bottom of the underground space 5 or discharged into the sewage through a pipe arranged in the sewage pipe.
Since the underground space 5 can be formed to have a sufficiently large volume, the storage capacity of human waste is large, and there is no fear that it will be filled in a short period of time such as a few days.
In the structure that discharges to the sewage with the arrangement pipe, there is no need to worry about the capacity for storing human waste.

  Further, in the disaster toilet 1, the upper opening of the storage box 2 that is upside down is closed by the toilet seat 9, and the inside of the drop-in part 10 is normally blocked up and down by the receiving part 11 including the damper plate 22 at normal times. Therefore, even if urine is stored in the underground space 5 or the space 5 communicates with sewage, the amount of odor leaking outside the toilet seat 9 is small. Furthermore, since it is the constituent member of the receiving part 11 that can be seen even if the pouch 18 is looked into, there is no fear of a conventional manhole toilet. For this reason, the use environment of the toilet 1 at the time of a disaster improves.

[Example 2]
FIG. 10 uses the lid 4 of the first embodiment as the side table 33. The four support legs 34 are stored together in the storage box 2 and fixed to the four corners of the lower surface of the lid 4 with bolts (not shown). Since the side table 33 is independent of the disaster toilet 1 installed, it may be anywhere. However, if the side table 33 is placed near the disaster toilet 1, it is useful because it is within the reach of a small amount of baggage, clothes or infants. .

Example 3
FIG. 11 shows an example in which a toilet 18 is provided on the lid 4 of the first embodiment, and a drop portion 10 similar to the toilet bowl 3 is attached to the lower surface thereof. The toilet 18 is normally closed with a child lid 35. By removing the child lid 35, inserting the dropping part 10 into another underground space 5 (manhole), and hanging the lid 4 over the underground space 5, a Western-style toilet using the original toilet 3 Apart from that, it can be used as another disaster toilet 36 (Japanese style). The size of the drop-in portion 10 in this case is a size that fits in a space above the base plate 12 of the toilet seat inside the storage box 2 in which the toilet bowl 3 is stored.
The third embodiment can increase the number of toilets required at the time of a disaster and can also be used as a side table as shown in FIG. 11 when the necessity does not arise.

Example 4
FIGS. 12 to 15 show the fourth embodiment, which is basically composed only of the toilet bowl 3 of the first embodiment, and does not have anything corresponding to the storage box 2. Moreover, since it is adapted to the manhole of the sewer and the iron frame 8 of the ground opening is circular, the base plate 12 and the back guard 16 are circular and have a size within the radius of the iron frame 8 accordingly. The dropping part 10 has a rectangular tube shape, and the long side in the cross section is within the radius of the iron frame 8. The inside of the drop-in part 10 is blocked up and down by a receiving part 11. The specific configuration of the receiving portion 11 is the same as that in the first embodiment.

In the normal storage state, the toilet bowl 3 is suspended upside down inside the manhole with the back guard 16 positioned downward and the periphery of the base plate 12 engaged with the iron frame 8 (FIG. 13).
Reference numeral 37 denotes an iron lid of a manhole, which is placed above the base plate 12 to close the manhole.
In the event of a disaster, the iron lid 37 is removed and the toilet 3 is removed from the manhole. Next, the toilet 3 is set upright, and the base plate 12 is fitted again into the iron frame 8 to complete the disaster toilet 1 (FIGS. 14 and 15).
The function and use mode of the toilet are the same as in the first embodiment.

  Since the storage box 2 is not provided, it is necessary to attach a member necessary as a toilet at the time of a disaster to the toilet bowl 3. Moreover, since the member like the cover 4 of Example 1 is not provided, a thing like a side table cannot be produced. However, it can be kept suspended inside a normal manhole and does not require a storage space. Moreover, a disaster victim can install immediately at the time of a disaster, and also a special technique is not required for installation.

FIG. 16 shows the receiving portion 11 in the fifth embodiment. Although basically the same as the receiving portion 11 of the first embodiment, in the fifth embodiment, a pressure relief valve 38 that rotates only upward is disposed on a part of the first swash plate 20. When the pressure in the underground space 5 suddenly increases for some reason in the normal state in which the damper plate 22 is closed, the pressure release valve 38 is released upward by that pressure (FIG. 16), and the dropping portion 10 The pressure in the lower space at is released into the upper space. Thereby, it is possible to prevent the entire toilet 3 from being blown up from the underground space 5.
The pressure relief valve 38 is urged in the closing direction by a spring or the like so as not to be opened by a normal blow-up level. Moreover, you may provide in other locations, such as a location above the receiving part 11 in the surrounding wall of the square tube 19. FIG.

  In the toilet 1 at the time of the disaster, the discharged human waste is temporarily stored in the damper plate 22 of the receiving portion 11 and is released into the underground space 5 by rapidly opening the smooth surface of the damper plate 22 and the damper plate 22. If water that can be poured at this time is obtained, it is of course preferable to use it at the same time. Such water can be pumped up from a tank installed beside the toilet 1 at the time of a disaster, or dropped naturally, or can be structured to be fed from a water pipe when water supply is functioning. As irrigation water, rainwater or sewage used for washing dishes can be used. In addition, it is effective for sliding urine if the drainage used for hand washing is guided above the receiving part 11 of the toilet 1 at the time of disaster to keep the smooth surface wet.
