DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0012] Next, embodiments of the present invention will be described with reference to the attached drawings to facilitate understanding of the present invention. Note that in the drawings, parts that are not relevant to the description may be omitted.
[0013] The portable toilet 10 according to one embodiment of the present invention can be loaded onto a light truck and transported to a disaster area, for example, where the internal space can be expanded for use. The portable toilet 10 includes a main body portion 20 and an extension portion 30, as shown in FIGS. In the following description, the side on which a door 204 (described later) is provided is regarded as the front side.
[0014] The main body 20 has space forming members 202a to 202e, a door 204, a first caster 206, a slide rail 208, a washstand 210, and tanks 212a to 212d, and a space is formed inside. The space forming members 202a to 202e are plate-like members for forming the front wall surface, the rear wall surface, the right wall surface, the ceiling surface, and the floor surface, respectively. A ventilation fan 220 is provided on the upper portion of the space forming member 202b that constitutes the wall surface on the rear side. A mirror (not shown) is attached to the space forming member 202c that constitutes the wall surface on the right side.
[0015] The door 204 is provided on the space forming member 202a that constitutes the wall surface on the front side, and the rotation axis thereof is disposed on the side of the extension section 30. That is, the door 204 is disposed so as to open to the left (see FIG. 1).
[0016] The first casters 206 have stoppers, and a plurality of them are provided on the lower surface of the main body 20 .
[0017] A total of four slide rails (an example of a guide member) 208 are provided extending in the left-right direction, and are respectively positioned at the upper and lower parts of space forming member 202a constituting the front wall surface and space forming member 202b constituting the rear wall surface.
[0018] As shown in Fig. 4, the washstand 210 is composed of at least a washbowl 222 and a water tap 224 arranged near the door 204, and the top plate 226 of the stand on which the washbowl 222 is attached is arranged to extend in the front-to-rear direction (the direction intersecting the direction in which the space is expanded). A portable power source (not shown) is installed on the top plate 226 to supply power to each part of the mobile toilet 10 (for example, the above-mentioned ventilation fan 220 and the pump and LED lighting device described below). The portable power source is configured so that an external power source can be connected from outside the mobile toilet 10 via a cable (not shown). This external power source is, for example, a solar power generation device or an engine generator. 8, a shelf board (an example of a support member) 228 is provided at a predetermined height position on the lower part of the back side of the washbasin 210. The shelf board 288 is disposed at a predetermined height position from the space forming member 202e, which is the floor surface, and a space is formed below the shelf board 288.
[0019] Tanks 212a to 212d (see FIG. 4) are transportable tanks for storing purified water or wastewater, such as polyethylene tanks. Tanks 212a to 212d are placed under washstand 210 and secured by belts (not shown). Of these multiple tanks 212a to 212d, tank 212a is a water supply tank placed below washbasin 222 and stores water to be supplied to water supply tap 224 via a pump (not shown). Tank 212b is a drainage tank placed below washbasin 222 and stores drainage water from washbasin 222 via flexible drainage pipe 230, as shown in Fig. 6. Tanks 212c and 212d are placed on shelf 228 as spare tanks to be used as water supply tanks or drainage tanks.
[0020] The expansion section 30 is supported on both sides by four slide rails 208, and is stored in the main body section 20 in the stored state, and is advanced by being pulled out from the main body section 20 in the used state (see the arrow in Figure 1), thereby expanding the internal space. The expansion section 30 includes expansion space forming members 302a to 302e, a second caster 306, and a toilet device 310.
[0021] The expansion space forming members 302a to 302e are plate-shaped members for forming the front wall, the rear wall, the left wall, the ceiling and the floor, respectively. When viewed from the left side as shown in FIG. 2, the expansion space forming members 302a, 302b, 302d and 302e are located inside the space forming members 202a, 202b, 202d and 202e, respectively. Of these, an openable and closable window 320 is provided in the upper portion of the expansion space forming member 302c that constitutes the wall surface on the left side surface side. The expansion space forming member 302d constituting the ceiling surface is provided with an LED lighting device (not shown) that illuminates the inside. The upper surface of this expansion space forming member 302d, i.e., the roof, is inclined so that the height on the side away from the main body part 20 (the side in the direction in which the extension part 30 advances) is lower than the side closer to the main body part 20. A drainage hole is provided on the side of the roof away from the main body part 20 to drain accumulated rainwater, and the rainwater passes through this drainage hole and is drained into a rain gutter (not shown) provided on the upper side of the window 320. This prevents rainwater from flowing into the interior from between the main body part 20 and the extension part 30.
[0022] The second caster 306 is provided on the lower part of the left side surface opposite the main body 20, and can move up and down. The vertical position of the second caster 306 that extends downward and touches the ground is fixed by a fixing means 308.
[0023] The toilet device 310 is provided with a toilet seat and can dispose of excrement by sealing it in a plastic bag. The opening of the bag is sealed by thermocompression. The toilet device 310 is disposed so as to face the shelf board 228 in a plan view. Below the toilet device 310, which is the lower part of the expansion section 30, a discharge space S1 is formed into which a sealed bag containing excrement falls and accumulates, as shown in Fig. 7. Outside this discharge space S1 (the left side surface of the mobile toilet 10), a door 330 is provided, as shown in Fig. 2. The door 330 opens upward and is lifted up by a gas spring 332.
[0024] A step 340 on which a user seated on the toilet seat places their feet is provided in front of the toilet device 310 in plan view (on the lower right side of the toilet device 310 when viewed from the front side of the mobile toilet 10) as shown in Fig. 4. The upper surface of this step 340 is set to be lower than the lower surface of the shelf board 228 as shown in Fig. 8, and when the extension part 30 is stored in the main body part 20, it moves to the lower side of the shelf board 228. As shown in FIG. 7, on the front side of the toilet device 310 (next to the discharge space S1), an independent storage space S2 for storing toilet paper and other fixtures is formed.
[0025] Next, we will explain how to use the mobile toilet 10. The mobile toilet 10 is used according to the following steps P1 to P4. However, where possible, some steps may be performed in parallel.
[0026] (Step P1) The mobile toilet 10 is transported to an installation location. Note that the installation location may be indoors or outdoors.
[0027] (Step P2) The extension part 30 is pulled out by an operator from the main body part 20. The extension part 30 is guided by the slide rail 208 and advances from the main body part 20, and the internal space is expanded. Next, the worker advances the second caster 306 downward. The vertical position of the second caster 306 that has touched the ground is fixed by the fixing means 308. Next, the worker uses a locking means (not shown) to fix the extension part 30 so that it does not move relative to the main body part 20. Finally, once power is supplied from the portable power source to the ventilation fan 220, LED lighting, pump, etc., the mobile toilet 10 is ready for use.
[0028] (Step P3) The waste material is sealed in a bag by the toilet device 310 and falls into the discharge space S1 below the toilet device 310. Since a discharge space S1 is provided below the toilet device 310, the position of the toilet seat (height position from the floor surface, which is the space forming member 202e) is necessarily high; however, a step 340 is provided in front of the toilet device 310, and the height position of the toilet seat from the top surface of the step 340 is set to an appropriate predetermined dimension, allowing the user to use the toilet comfortably. When the sealed waste accumulates in the discharge space S1, it is removed through the door 330 and treated as combustible material.
[0029] (Step P4) When the portable toilet 10 is to be removed from the installation site, the above steps are reversed. Here, when the extension part 30 is stored in the main body part 20, as shown in FIG. 8, the height position of the upper surface of the step 340 protruding in front of the toilet device 310 is set to be lower than the shelf board 228 located in front of it, so that the step 340 moves below the shelf board 228. Thus, the portable toilet 10 is more compact when stored, as shown in Figures 4 and 5, than if it were not so configured.
[0030] As described above, the mobile toilet 10 according to this embodiment can be transported to a location where it is needed and used.
[0031] Although the embodiment of the present invention has been described above, the present invention is not limited to the above-mentioned embodiment, and all changes in conditions that do not depart from the gist of the present invention are within the scope of application of the present invention.
