Description

[Technical Field]

[0001] The present invention relates to a toilet device for use in emergencies when a disaster such as an earthquake occurs. [Background technology]

[0002] Conventionally, so-called temporary toilets have been known as emergency toilets to be used in the event of a disaster such as an earthquake. These temporary toilets store human waste in a storage tank, and after a certain period of use, the human waste can be collected by a vacuum truck, allowing the toilet to continue to be used.

[0003] However, disasters such as earthquakes often affect a wide area, and the number of such temporary toilets is limited, so not many victims can use them. Also, roads may be destroyed by earthquakes, and in such cases, vacuum trucks cannot collect human waste.

[0004] For example, Japanese Patent Application Laid-Open Publication No. 2009-77773 discloses "an emergency toilet that is buried underground and used in the event of a disaster, which comprises a channel concrete block having a human waste inlet and a channel through which the human waste introduced through the inlet flows, and a catch basin concrete block that is connected to the channel and has a bottom surface that is lower than the channel."

[0005] However, the emergency toilets described above require concrete blocks with channels for flushing human waste to be buried underground beforehand. This means that, like permanent toilets that are not normally used, the concrete channels and concrete blocks for the catch basin must be buried beforehand, which results in significant construction costs and places limitations on where they can be installed.

BEST MODE FOR CARRYING OUT THE INVENTION

[0014] Hereinafter, a first example of the emergency toilet device 10 will be described with reference to the illustrated embodiment. The emergency toilet device 10 of this example has an attachment part 50 and a separation part 100, and can be placed in an existing manhole 200 that has already been installed.

[0015] That is, the upper end 201 of an existing manhole 200 has a frame 300 already installed as an existing manhole frame, and a cover (not shown) that serves as a lid for the manhole 200 is placed on the frame 300. This lid is removed, and its attachment part 50 is attached to an opening 320 in the frame 300 that is circular in plan view, and the separation part 100 is hung from the attachment part 50. The frame 300 to which the disaster toilet device 10 of this embodiment is attached may be a conventionally known one.

[0016] The frame 300 has a base 310 that is substantially rectangular in plan view and a substantially circular opening 320 that communicates with the manhole 200. In cross-sectional view, the frame 300 has a wall-shaped edge 330 and a wall-shaped second edge 340 at its outer edge, each of which is arranged concentrically with the opening 320 in plan view. In cross-sectional view, a groove 350 is formed between the edge 330 and the wall-shaped second edge 340 arranged at its outer edge, and this groove 350 is also arranged concentrically with the opening 320 in plan view. Four ribs 360 are formed radially from the second edge 340. The base 310 may also preferably be circular (not shown).

[0017] The disaster toilet device 10 of this embodiment has the attachment part 50 and the separation part 100 as described above, and may further have a temporary toilet 400 and a tent 450. The temporary toilet 400 is preferably placed on the attachment part 50 and enclosed by the tent 450 to block views from outside. The temporary toilet 400 is preferably the YT type manufactured by Ito Iron Works Co., Ltd. Similarly, the tent 450 is preferably the ALT type manufactured by Ito Iron Works Co., Ltd. The temporary toilet 400 has a passageway (not shown) for passing human waste, and the passageway can be connected to communicate with the opening 320, which is circular in plan view, in the frame part 300.

[0018] The portable toilet 400 also has a base 510 that serves as a stand, and the base 510 may be connected to the above-mentioned tent 450. The tent 450 also has foundations 500, 500 that serve as its foundation, and the foundations 500, 500 are connected to ropes 520, 520. The foundations 500, 500 act as anchors, and are preferably placed so that they are buried in the ground. The tent 450 can be secured by the foundations 500, 500.

[0019] The attachment portion 50 is literally used to attach the separation portion 100. The attachment portion 50 has a hook portion 51 that is U-shaped in side view, a flat main body portion 52, a hanging portion 53 that hangs the separation portion 100, and a bent portion 54 that bends the main body portion 52. The hook portion 51 has a hook tip portion 51a that is its tip. As will be described later, the tip portion 54a of the bent portion 54 can come into contact with the manhole 200. Therefore, the hook portion 51 and the bent portion 54 are bent in the same direction relative to the main body portion 52 in a front view. Therefore, the hook tip portion 51a and the tip portion 54a are bent to the left in a front view in FIG. 3A.

[0020] The hook portion 51 is attached so as to be suspended from the frame portion 300, and can be attached so as to be hooked into the groove portion 350 in the frame portion 300.

[0021] Furthermore, the hanging part 53 is attached to the main body part 52 and has a hole 53a that serves as a hole. Hooks 118, 118, 118, 118 for hanging in the separation part 100, which will be described later, can be attached to the hole 53a. The material of the attachment part 50 can be metal such as iron, stainless steel, or aluminum.

[0022] The separation unit 100 is, so to speak, basket-shaped and has a mesh-like main body 110. The mesh spacing of the main body 110 is preferably 4 to 10 millimeters. This is because the solid portion (feces) of the human waste is temporarily retained while the liquid portion (urine) flows downward, and the solid portion can then be easily washed away during cleaning. This will be described later.

[0023] The separation section 100 also has an upper portion 130 that opens and is located at the upper end, a lower portion 160 that is located at the lower end, and an intermediate portion 140 that is located therebetween. The separation section 100 also has the above-mentioned main body portion 110 that is attached to the upper portion 130, the intermediate portion 140, and the lower portion 160.

[0024] The separation section 100 is configured so that the diameter gradually decreases from the upper section 130 through the middle section 140 to the lower section 160. In other words, the main body section 110 has a tapered shape in a side view.

[0025] Moreover, the upper portion 130 has four handles 131 arranged thereon to serve as handles for lifting the separating portion 100.

[0026] The main body 110 preferably has a mesh shape, with mesh spacing of 4 to 10 millimeters, as this allows the solid content to be temporarily retained, as will be described later.

[0027] Furthermore, the upper portion 130 is preferably circular in plan view to prevent lateral expansion and is formed by a ring-shaped rope. The middle portion 140 is preferably circular in plan view and is formed by a ring-shaped rope. The lower portion 160 is preferably circular in plan view and is formed by a ring-shaped rope. The upper portion 130, the middle portion 140, and the lower portion 160 are configured to gradually decrease in diameter. The inside of the ring-shaped lower portion 160 has a mesh-shaped lower mesh portion 165. Therefore, the separation portion 100 can be formed by attaching a mesh-shaped main body portion 110 to the ring-shaped upper portion 130, middle portion 140, and lower portion 160. Therefore, the separation portion 100 has a tapered shape in side view, with the upper portion 130 being larger and the lower portion 160 being smaller.

[0028] As described above, the upper portion 130, the middle portion 140, and the lower portion 160 are preferably made of, for example, polyethylene, and when the polyethylene rope is configured into a ring shape, it stretches little, can maintain its shape, and can be folded and stored when not in use.

[0029] The main body 110 has four side ropes 115. These side ropes 115 are arranged in the lower part 160, pass through the middle part 140, and reach above the upper part 130, and their upper ends 116 can be detachably attached with hooks 118 for hanging.

[0030] The four side ropes 115 are respectively arranged at angles of 45 degrees, 135 degrees, 225 degrees, and 315 degrees in a plan view of the main body 110, and reinforce the main body 110. Furthermore, upper ends 116 of the side ropes 115 are sewn into a loop, and a hanging hook 118 can be removably attached to them.

[0031] Of the four side ropes 115, the side ropes 115 arranged at 45 degrees and 225 degrees are united at the lower part 160, and the side ropes 115 arranged at 135 degrees and 315 degrees are united at the lower part 160. Therefore, they are arranged so as to cross each other in the lower mesh part 165 in a plan view.

[0032] The following experiment was conducted on the mesh size to be applied to the separation unit 100 in the emergency toilet device 10 of the first embodiment. This experiment was conducted to determine how the separation unit 100 separates water and solids depending on the mesh size used in the separation unit 100, and to what extent the solids remain in the separation unit 100. Instead of human waste, a mixture of liquid water (a substitute for urine, liquid) and solid miso paste (a substitute for feces, solid) was used. Miso paste was used because it is empirically believed to have a similar viscosity to feces.

[0033] This table shows the amount of residual mass measured when 0.1 liters of water and 200g of miso were poured into mesh sizes of 4mm, 10mm, and 14mm, 10 times, with one serving being 0.1 liters of water and 200g of miso.

[0034] TIFF2026036531000002.tif47111

[0035] The difference in weight of the water and miso mixture in Experiments 1, 2, and 3 above is due to errors in the addition of the miso. However, even after taking this into account, it was found that there was almost no difference between the 4 mm mesh spacing and the 10 mm mesh spacing. Furthermore, it was found that the 14 mm mesh spacing had a small amount of residual solid matter, causing it to leak out.

[0036] Thus, if the mesh spacing is between 4 mm and 10 mm, the liquid content of the human waste (water, urine substitute) will fall through, but most of the solid content (soybean paste, feces substitute) will remain. Therefore, by applying such a mesh to the main body 110 of the separation unit 100 and to the lower mesh portion 165 on the inside of the lower portion 160, the solid content and the liquid content can be separated while the solid content can be left in the separation unit 100. Therefore, the disaster toilet device 10 of the first embodiment allows the solid content to remain in the separation unit 100 while allowing the liquid content to fall into the manhole 200, thereby reducing the total amount of human waste captured in the separation unit 100 by the amount of the liquid that has fallen. Therefore, by reducing the amount of human waste remaining in the separation unit 100, the number of times the device is used can be increased.

[0037] The mesh spacing referred to here is preferably 4 to 10 mm for the spacing between the warp threads and the spacing between the weft threads that make up the mesh, but for example, a mesh with a spacing between weft threads of 12 mm and a spacing between warp threads of 10 mm is also included in the 10 mm mesh spacing, as this is considered to be within the range of the experimental results described above.

[0038] Next, a method for installing the disaster toilet device 10 of the first embodiment in an existing manhole 200 will be described. The mounting portion 50 is arranged on a frame portion 300 serving as an existing manhole frame, which is installed at the upper end 201 of the existing manhole 200. For example, four mounting portions 50 can be arranged on the frame portion 300 to correspond to the hanging hooks 118, 118, 118, 118 of the separation portion 100. The hook portion 51 of the mounting portion 50 is attached so as to be hooked into a groove portion 350 in the frame portion 300. In this way, the hook tip portion 51a of the hook portion 51 is attached to the groove portion 350 between the edge portion 330 and the wall-like second edge portion 340 at its outer edge, and the hook portion 51 can be arranged so as to climb over the edge portion 330. The number of attachment parts 50 is not limited to four, and can be arranged according to the number of hanging hooks 118 in the separation part 100. Therefore, it is preferable that the number of attachment parts 50 is four or more, or it may be four or less.

[0039] Hooks 118, 118, 118, 118 for hanging the separation unit 100 are attached to the holes 53a of, for example, four mounting parts 50 attached to the frame part 300 in this manner. This allows the separation unit 100 to be attached so as to be hung from the frame part 300 via the mounting parts 50. As described above, the hook tip 51a of the hook part 51 and the tip 54a of the bent part 54 are bent in the same direction in a front view ( FIG. 3A ). Therefore, the hook tip 51a is attached to the groove part 350 between the edge part 330 and the wall-like second edge part 340 at its outer edge, and the tip 54a contacts the manhole 200. Therefore, the mounting parts 50 can be positioned to remain upright, and tilting due to the weight of the separation unit 100 can be reduced.

[0040] Next, a method for cleaning the emergency toilet device 10 of the first embodiment after use will be described. The temporary toilet 400 and tent 450 are removed, and a rectangular plate member 600 is attached. The plate member 600 has a hole 610 through which a water or high-pressure washer hose 700 is attached, and water is sprayed to dissolve the solid matter G (feces) accumulated in the separation section 100 and discharge it through the manhole 200 into a sewer system (not shown). This means that securing water for flushing or installing a water source is not necessarily required when using the toilet device. Note that the solid matter G may include not only feces but also toilet paper.

[0041] Furthermore, as described above, the emergency toilet device 10 can be easily cleaned by attaching a water or high-pressure washer hose and spraying water. This eliminates the need for a vacuum truck to remove human waste when water and sewerage systems are restored, allowing for easy restoration to normal conditions. Furthermore, the emergency toilet device 10 of the first embodiment can be easily attached to the frame 300 placed on the manhole 200 by removing the lid (not shown). This eliminates the need for flushing equipment, which was required for conventional emergency toilets, and significantly reduces installation costs. Thus, the emergency toilet device 10 of the first embodiment solves the problem of conventional emergency toilets, where waste falls into a waterless manhole and accumulates inside the manhole, preventing drainage when the water supply is restored. Furthermore, it also solves the problem of the accumulated waste solidifying and making it difficult to collect with a vacuum truck. Furthermore, if waste accumulates in the manhole, drainage problems (blockages) caused by the accumulation of waste can be avoided when the water supply is restored.

[0042] In addition, the attachment part 50 and separation part 100 in the disaster toilet device 10 of the first embodiment can be removed and stored when not in use, and can be returned to their original state by removing them and attaching a manhole cover (not shown) to the manhole 200.
