Description

[Technical field]

[0001] The present specification discloses a portable toilet, which is a toilet that is movably supported on front and rear wheels. [Background technology]

[0002] Demand for outdoor toilets varies greatly depending on the season, whether there are events, etc. In order to flexibly respond to such changes in demand, mobile toilets that can be moved to a desired location have been proposed. For example, Patent Document 1 discloses a mobile toilet in which a toilet is installed in a loading box of a trailer towed by a tractor. In this vehicle-mounted toilet, the loading box is divided into a machine room located at the very front end of the loading box, a septic tank space located behind the machine room, and a toilet room located at the very rear end of the loading box. With such a mobile toilet, the installation location of the toilet can be changed relatively freely according to toilet demand. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-208359 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the mobile toilet of Patent Document 1, both the heavy machinery and the septic tank are located forward of the toilet room. As a result, the center of gravity of the cargo room is shifted to the front side of the cargo room, the weight balance of the mobile toilet as a whole is poor, and there is room for improvement in the stability of the mobile toilet.

[0005] Therefore, this specification discloses a portable toilet with improved stability. [Means for solving the problem]

[0006] The portable toilet disclosed in this specification comprises a box body supported for movement by front and rear wheels, and the internal space of the box body is characterized in that it is divided into a toilet room located in the fore-and-aft center of the internal space and into which toilet users enter, a toilet equipment room located at one of the front and rear parts of the internal space and in which toilet equipment including at least a water tank is disposed, and an electronic equipment equipment room located at the other of the front and rear parts of the internal space and in which electronic equipment is disposed. Effect of the Invention

[0007] According to the portable toilet disclosed in this specification, the heavy electronic devices and toilet equipment are distributed at the front and back of the box body, which results in a good weight balance for the portable toilet as a whole and improved stability of the portable toilet. [Brief description of the drawings]

[0008] [Figure 1] FIG. 1 is a side view of a portable toilet. [Diagram 2] 2 is a schematic cross-sectional view taken along the line AA in FIG. 1; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The mobile toilet will be described below with reference to the drawings. Figure 1 is a side view of the mobile toilet 10, and Figure 2 is a schematic cross-sectional view taken along line AA in Figure 1. In each figure, "Up", "Fr", and "Rh" indicate the upper side, the front side, and the right side, respectively.

[0010] The mobile toilet 10 is a toilet that can be moved to a different location by being towed by a towing vehicle, or by being mounted on the bed of a truck, or by being manually pushed and pulled. The mobile toilet 10 has a substantially box-like body 12 with a toilet unit mounted therein. The box-like body 12 is substantially rectangular with a length in the front-rear direction longer than the width direction. A door opening 14 (see FIG. 2) is provided in the center of the front-rear direction on the left side of the box-like body 12, and the door opening 14 is covered by a door 16 so as to be freely opened and closed. In this example, the door 16 is a double-opening sliding door that opens to both the left and right sides, but the door 16 may be of another type, such as a swing door, a flip-up door, or a folding door, as long as it can cover the door opening 14 so as to be freely opened and closed. However, as described later, the mobile toilet 10 of this example is intended for use with a wheelchair. For this reason, it is desirable that the door 16 be of a type that does not obstruct the entry of a wheelchair.

[0011] The internal space of the box body 12 is divided into a toilet room 24, a toilet equipment room 26, and an electronic equipment room 28 by two partition walls 22, 23. The front partition wall 22 and the rear partition wall 23 are provided in consideration of the positional relationship with the wheel arches 19, 21. That is, the wheel arches 19 of the front wheels 18 stand above the floor surface of the toilet room 24. Therefore, the part of the floor panel that overlaps with the wheel arches 19 is raised upward. The front partition wall 22 is a wall that stands above the floor panel at a position rearward of the raised part. The part in front of the front partition wall 22 becomes the toilet equipment room 26, and the part behind becomes the toilet room 24. Therefore, there is no protrusion due to the wheel arches 19 on the floor surface of the toilet room 24.

[0012] Similarly, the wheel arch 21 of the rear wheel 20 also protrudes upward from the floor surface of the toilet room 24. Therefore, the portion of the floor panel that overlaps with the wheel arch 21 of the rear wheel 20 protrudes upward. The rear bulkhead 23 is a wall that stands upward from the floor panel at a position forward of the protruding portion. The space behind this rear bulkhead 23 becomes the electronic equipment room 28. Therefore, there is no protrusion on the floor surface of the toilet room 24 caused by the wheel arch 21 of the rear wheel 20.

[0013] The toilet room 24 is a space where toilet users enter. The toilet room 24 is provided with a toilet body 30 and washstand counters 32a and 32b. The washstand counter 32a is a washstand counter for wheelchairs. The washstand counter 32a is fixed to a position on the side of the box body 12 that is higher than the handrails of the wheelchair, and there is a space between the bottom of the washstand counter 32a and the floor of the toilet room 24. Wheelchair users can easily use the washstand counter 32a by inserting their knees into the space between the washstand counter 32a and the floor. The washstand counter 32b is a washstand counter for people who are standing. The washstand counter 32b is fixed to a position on the side of the box body 12 that is slightly higher than the washstand counter 32a.

[0014] Here, as described above, the mobile toilet 10 of this example is also intended for use with a wheelchair. Therefore, the floor surface of the toilet room 24 is secured to be large enough for a wheelchair to turn around. The floor surface means a surface that is connected without any steps at the lower end of the toilet room 24. The circle C in FIG. 2 indicates the turning space C required for a general wheelchair to turn. As is clear from FIG. 2, this example can secure the floor surface required for a wheelchair to turn. In FIG. 2, the turning space C partially overlaps with the washbasin counter 32a, but as described above, the washbasin counter 32a is installed away from the floor surface, so the underside of the washbasin counter 32a can also be used as a floor surface on which the wheelchair runs.

[0015] The electronic equipment room 28 houses electronic equipment such as a battery 39a, an outdoor air conditioner unit 39b, an electronic equipment control panel 39c (see FIG. 2), etc. The outdoor air conditioner unit 39b is disposed between a pair of left and right wheel arches 21. An opening (not shown) that allows outside air to flow in and out is formed in a portion of the rear wall of the box body 12 that faces the outdoor air conditioner unit 39b. The battery 39a supplies power to lighting, air conditioners, a pump 38 (described later), etc. The electronic equipment control panel 39c distributes and supplies power from the battery 39a to various electronic equipment as necessary, and controls the operation of the various electronic equipment. Hereinafter, electronic equipment such as the battery 39a, the outdoor air conditioner unit 39b, and the electronic equipment control panel 39c are referred to as "electronic equipment."

[0016] The toilet equipment room 26 is further divided into upper and lower parts by the intermediate plate 25. A wastewater tank 36 for storing wastewater and a purified water tank (not visible in Figs. 1 and 2) for storing purified water are arranged side by side in the width direction on the upper side of the intermediate plate 25. A pump 38 for pumping water is installed on the lower side of the intermediate plate 25. The pump 38 is arranged between a pair of wheel arches 19 on the left and right. Hereinafter, equipment used for supplying and draining water to the toilet body, such as the wastewater tank 36, the purified water tank, the pump 38, etc., will be referred to as "toilet equipment". The pump 38, the wastewater tank 36, the purified water tank, the toilet body 30, the washbasin counters 32a, 32b, etc., constitute a toilet unit that provides toilet functions. A steering wheel 42 (see Fig. 2) that is operated when changing the angle of the front wheels 18 is also provided on the lower side of the intermediate plate 25.

[0017] 1 and 2, the front bulkhead 22 or the outer wall of the box 12 is provided with an opening / closing door through which the toilet facility room 26 can be accessed. The operator can enter the toilet facility room 26 through this opening / closing door. Similarly, the rear bulkhead 23 or the outer wall of the box 12 is provided with an opening / closing door through which the electronic equipment facility room 28 can be accessed, and the operator can access the electronic equipment facilities 39a, 39b, and 39c through this opening / closing door.

[0018] As is clear from the above description, in this example, the toilet equipment is disposed at the front of the box body 12, and the electronic equipment is disposed at the rear of the box body 12. This makes it possible to stabilize the weight balance of the entire box body 12, and to stabilize the mobile toilet 10. That is, as described above, the toilet equipment includes a tank for storing water, and is relatively heavy (e.g., several hundred kg). In addition, the electronic equipment is often very heavy, and the total weight of all the electronic equipment can reach several hundred kg. If such heavy objects are disposed together at the front or rear of the box body 12, the center of gravity of the box body 12 is biased to one side in the front-rear direction, and the stability of the box body 12 deteriorates. On the other hand, as in this example, the toilet equipment, which is a heavy object, and the electronic equipment equipment, which is also a heavy object, are disposed separately at the front and rear of the box body 12, and the weight balance of the mobile toilet 10 can be stabilized. Furthermore, by disposing the electronic equipment equipment, such as the battery 39a, and the toilet equipment, such as the sewage tank 36, at a distance from each other, it is possible to effectively prevent the electronic equipment equipment from being splashed with water.

[0019] As described above, in this example, the floor surface of the toilet room 24 is required to be a flat surface of sufficient size to enable use by a wheelchair. On the other hand, the upper parts of the front wheels 18 and the rear wheels 20 of the floor panel are locally raised by the wheel arches 19, 21. This raised part hinders the movement of a wheelchair, so the upper parts of the front wheels 18 and the rear wheels 20 are difficult to use as the floor surface of the toilet room 24. By using the upper parts of the wheels 18, 20 including such non-flat surfaces as the equipment rooms 26, 28 instead of as the toilet room 24, the internal space of the box body 12 can be used more effectively. As a result, the toilet room 24 can be secured to be large enough for use by a wheelchair without increasing the size of the box body 12.

[0020] Here, as is clear from FIG. 1, in this example, the front wheels 18 have a larger diameter than the rear wheels 20. In this example, the toilet equipment room 26 is provided above the large-diameter front wheels 18, and the electronic equipment room 28 is provided above the small-diameter rear wheels 20. This is because the toilet equipment room is generally larger than the electronic equipment. That is, as described above, the front bulkhead 22 is located behind the wheel arch 19 of the front wheels 18, and the rear bulkhead 23 is located forward of the wheel arch 21 of the rear wheels 20. Therefore, when the front wheels 18 have a larger diameter than the rear wheels 20, the space enclosed by the front wall and the front bulkhead 22 of the box body 12 tends to be larger than the space enclosed by the rear wall and the rear bulkhead 23 of the box body 12. By arranging the large toilet equipment in the front space that tends to be large, the internal space of the box body 12 can be used more efficiently.

[0021] As is clear from the above description, in this example, the internal space of the box body 12 is divided into a toilet room 24 where the toilet user enters, a toilet equipment room 26 located in front of the toilet room 24, and an electronic equipment room 28 located behind the toilet room 24, and the toilet equipment and electronic equipment are distributed and arranged at the front and rear of the box body 12. With this configuration, the weight balance of the mobile toilet 10 as a whole can be stabilized. In the above description, the toilet equipment room 26 is provided at the front of the box body 12, and the electronic equipment room 28 is provided at the rear of the box body 12, but this arrangement may be reversed. That is, the toilet equipment room 26 may be provided at the rear of the box body 12, and the electronic equipment room 28 may be provided at the front of the box body 12. In the above description, the front wheel 18 has a larger diameter than the rear wheel 20, but the two wheels 18, 20 may have the same diameter, or the front wheel 18 may have a smaller diameter than the rear wheel 20.
