[0024] Specific examples of this embodiment will be described below with reference to the drawings. Figure 1 shows a perspective view of a portable toilet with a manual washer according to a first embodiment of the present invention when in use. The portable toilet requires a base 30 with a predetermined height dimension (the size in the height direction Y) so that the user can sit comfortably on the seat 10 and temporarily store excrement.

[0025] However, since a portable toilet is a portable, simple toilet, it is necessary to consider its compact size and ease of carrying when transporting it. In this embodiment, the base 30 is foldable in the height direction Y, and the washer mechanism 50 is configured to be foldable (can be lowered) in the horizontal direction X by a position change mechanism formed by a hinge or the like.

[0026] In Figure 1, seat 10, on which the user sits, has an egg-shaped opening in the center, rounded edges for comfortable sitting, and protrusions 11 and 12 at the rear. Seat base 20, which also has an egg-shaped opening like seat 10, serves as a cover for base part 30 and is fitted and fixed. Seat base 20 also has seat hinges 21 and 22 that fit with seat 10 at protrusions 11 and 12.

[0027] The seat 10 is attached to the seat base 20 so as to be rotatable about its rear end from a horizontal position to an angle exceeding a vertical position, as indicated by the arrow R, with the seat hinges 21 and 22 as the rotation axis, and so as to be removable. In this embodiment, it is preferable to provide a top cover that uses the seat hinges 21 and 22 to cover the seat 10 (not shown) and is rotatable in the same manner as the seat 10.

[0028] The portable toilet includes a water supply unit 40 that can be fixed to and detached from the base 30 or the seat 20, and a washer mechanism 50 that is disposed on the seat 20 and has a nozzle 51 and a cleaning hole 51-1 that can rotate in a vertical plane (within a vertical plane) in the height direction. In addition, a lever 53 is provided on the right end of the base 30 when assembled.

[0029] Rod 52 is fixed to the bottom of lever 53 and passes through hole 34-1 in upper right plate 34 of base 30 so that it can be connected to washer mechanism 50. A spherical grip 53-1 is attached to the upper end of lever 53. Although lever 53 is located on the right side in FIG. 1, it can also be located on the left side depending on the user's dominant hand.

[0030] The nozzle 51 and the cleaning hole 51-1 formed at the tip of the nozzle 51 are configured to be able to spray liquid (specifically, warm water, water, etc.). When washing the buttocks, the cleaning hole 51-1 is manually positioned near the user's buttocks. When the nozzle 51 is not in use, i.e., when excreting, the washer mechanism 50 retracts the nozzle 51 and cleaning hole 51-1 rearward so that they do not get in the way.

[0031] Nozzle 51 is moved by manually rotating lever 53 along a vertical plane via rod 52 and washer mechanism 50. This realizes a manual portable toilet that requires no external power. Arrow S indicates the direction in which lever 53 is rotated when washing the buttocks (clockwise when viewed from the right).

[0032] A predetermined amount or more of the liquid (hot water, water, etc.) to be supplied to the nozzle 51 can be stored in the water supply unit 40. This predetermined amount is determined by the spray speed from the cleaning hole 51-1, the amount sprayed per unit time, and the duration of spraying, so that a 2-liter PET bottle 41 is nearly full. The position of the PET bottle 41 is determined by turning the container upside down and positioning its outlet (cap) at least 40 to 50 cm above the position of the nozzle 51 or cleaning hole 51-1, and utilizing the head of water at that position.

[0033] The PET bottle 41 is not limited to a configuration in which the injection pressure is obtained by the head of water, but may be a pressure accumulator container made of polyethylene, the inside of which is pressurized by a manual pump, and fixed near the seat 20. In this case, the manual pump is pulled out from the pressure accumulator container in advance and pressurized to compress the air inside the container.

[0034] In Figure 1, PET bottle 41 is held at the rear left by fixture 46, one end of which is fixed to seat 20, and an annular receiver 43 connected to fixture 46. Water supply tube 45 and PET bottle 41 are connected by a flexible connecting hose using connector 44 shaped to match the cap of PET bottle 41. The bottom of PET bottle 41 may be formed with opening 42 for pouring water and venting air. It is also preferable to attach a lid to this opening 42 to prevent water leakage even when the bottle is turned upside down.

[0035] The base 30 is fixed to the seat 20 by fitting or screws, etc., and is strong enough to withstand a user's sitting, with a maximum load capacity of 100 kg to ensure comfort even for larger users. The height of the base 30 is 40-50 cm, and the depth is 50-60 cm, so it can be used in a comfortable position without putting strain on the legs or lower back. When not in use as a portable toilet, the base 30 can be used as a container box, step stool, chair, etc.

[0036] The base 30 has a front plate 31 and a rear plate 32 that are foldable relative to a bottom plate 36, and in FIG. 1, they are assembled upright on the bottom plate 36 and the seat 20. On the right side of the base 30, an upper right plate 34 and a lower right plate 33 are attached to the bottom plate 36 so as to be foldable via an intermediate shaft 35. Although not shown, the left side of the base 30 is the same as the right side.

[0037] An excrement bag and a coagulant (not shown) are placed in the internal space of the assembled base 30. The coagulant is made of an airtight, moisture-proof aluminum bag. The excrement bag that processes the excrement is made of a durable, odor-resistant, high-density polyethylene material.

[0038] 1, the base 30 is assembled upright on the bottom plate 36 and seat 20, just like the front and rear. The base 30 is preferably made of a general-purpose resin such as polypropylene, which has relatively high strength, excellent chemical resistance (including acid and alkali), and no moisture absorption.

[0039] The washer mechanism 50 will be described in detail below with reference to the drawings. Figure 2 is a partial cross-sectional front view of the washer mechanism 50, showing the lever 53 and rod 52 assembled together. The plate 55 is a roughly U-shaped metal plate with an open top that supports the components of the washer mechanism 50.

[0040] The washer mechanism 50 is equipped with a position change mechanism that supports the plate 55 so that it can move between a use position and a retracted position. The position change mechanism in Example 1 is formed by a flange 54 and a hinge 56. The flange 54 is fixed to the underside of the seat 20 and is connected to the plate 55 via the hinge 56, suspending the main part of the washer mechanism 50 (in a hanging state). Figure 2 shows the portable toilet in use, i.e., with the plate 55 in the use position. The plate 55 rotates around the hinge 56 relative to the seat 20 as indicated by the arrow T and is positioned in the vertical direction (height direction Y).

[0041] Receiving portion 58 is fixed to the left side of the lower end of plate 55, receiving portion 57 is fixed to the right side, and hollow shaft 60 is rotatably supported by receiving portions 57, 58. Rod 52 is inserted into receiving portions 57, 58 from the direction of arrow U and is fixed to and integrated with hollow shaft 60 by fixing pin 61. This allows hollow shaft 60 to rotate in sync with lever 53, providing a solid operational feel.

[0042] Nozzle 51, formed in an arc shape, is fixed to stay 59, which is further fixed to hollow shaft 60 via stay 59. Valve 62 is fixed to the right side of plate 55 and has on-off valve 62-1 and on-off lever 62-2 that rotates to open and close on-off valve 62-1. Water supply tube 45 is made of an extremely soft and flexible resin such as polyurethane or nylon that is ideal for compact piping, and is connected from water supply part 40 to the inlet of valve 62.

[0043] Nozzle tube 64 is made of the same material as water supply tube 45, and is connected from the outlet of valve 62 to nozzle 51. Valve 62 is preferably a small globe valve or ball valve with a lever-type handle.

[0044] 3 and 4 are left side views of the washer mechanism 50. Fig. 3 shows the nozzle 51 and cleaning hole 51-1 retracted to the rear, while Fig. 4 shows the lever 53 rotated to spray water or hot water from the cleaning hole 51-1. The stay 59 is biased by a spring 65 and positioned by a protrusion 55-1 on the plate 55.

[0045] The spring 65 is provided between a pin 55-2 set in the plate 55 and a stay pin 59-1 standing upright on the stay 59. The opening / closing lever 62-2 is connected to the stay 59 by the stay pin 59-1 as a link mechanism. Figure 3 shows the opening / closing valve 62-1 in a closed state.

[0046] When washing the buttocks, the lever 53 is rotated counterclockwise as viewed in Figures 3 and 4 against the bias of the spring 65. This causes the arc-shaped nozzle 51 and cleaning hole 51-1 to rotate around the hollow shaft 60 and reach a predetermined position. The opening / closing lever 62-2 is connected to the stay pin 59-1, so it rotates in the same way and the opening / closing valve 62-1 opens.

[0047] Since the nozzle 51 moves circularly around the hollow shaft 60, if the hollow shaft 60 is positioned lower, the space occupied when the nozzle 51 retreats to the rear can be reduced, thereby reducing the rear and depth dimensions of the base 30. Furthermore, the rotation angle of the lever 53 becomes smaller if the hollow shaft 60 is positioned further downward, improving usability.

[0048] However, because plate 55 becomes larger as hollow shaft 60 is positioned lower, washer mechanism 50 had to be made larger in the height direction. It is desirable for portable toilet base 30 to be foldable for ease of transportation, but the height dimension of washer mechanism 50 has been an obstacle.

[0049] In this embodiment, the foldable base 30 can be partially disassembled to allow for effective use, and the washer mechanism 50 can be tilted in the horizontal direction X by a position change mechanism. Figure 5 is a front view showing a partial cross section corresponding to Figure 2, illustrating the procedure for disassembling the washer mechanism 50. When disassembling for transportation, first, the fixing pin 61 is pulled out in the direction of arrow W to release the engagement between the hollow shaft 60 and the rod 52. Next, the rod 52 and lever 53 are pulled out in the direction of arrow V.

[0050] 6 is a front view showing the washer mechanism 50 in a state where it is laid down in the horizontal direction X (retracted position), and is a partial cross-sectional view corresponding to FIG. 2. The plate 55 rotates around the hinge 56 as indicated by the arrow P and is laid down in the horizontal direction X. This allows the washer mechanism 50 to have a constant apparent thickness and height, regardless of the position of the hollow shaft 60.

[0051] Next, disassembly for transportation is performed by removing the seat 20 upward from the base 30. Figure 7 shows a perspective view of the seat 20 removed. The seat 20 is removed in the direction of arrow Q by fitting it to the top plate 37 of the base 30 or by releasing screws or the like. The lower right plate 33 and lower left plate 73 are fitted to the bottom plate 36 so as to be able to fold down toward the inside of the base 30.

[0052] The upper right plate 34 and the upper left plate 74 are respectively attached to the lower right plate 33 and the lower left plate 73 via a hinge structure via intermediate shafts 35 and 75. The front plate 31 and the rear plate 32 are fitted into the bottom plate 36 of the base part 30 so as to be able to fold inward.

[0053] The procedure for folding the base part 30 in the height direction Y will be described. Fig. 8 is an explanatory diagram showing the folding procedure for the front plate 31 and the rear plate 32, and Fig. 9 is an explanatory diagram showing the folding procedure for the lower right plate 33, the lower left plate 73, the upper right plate 34, and the upper left plate 74.

[0054] First, the front plate 31 and the rear plate 32 are folded down as shown by the arrow F in Figure 8 and fit into the space inside the bottom plate 36. Then, the lower right plate 33, the lower left plate 73, the upper right plate 34, and the upper left plate 74 are folded inward as shown by the arrow G in Figure 9.

[0055] Figure 10 is a perspective view showing the portable toilet folded in the height direction Y. According to this embodiment, the washer mechanism 50 is tilted in the horizontal direction X as described in Figure 6, making the height dimension appear smaller, and the base 30 can be folded in the height direction as described in Figures 8 and 9, thereby making it possible to make it thinner as shown in Figure 10.

[0056] 6, the washer mechanism 50 is tilted in the horizontal direction X, and therefore can be accommodated in the internal space formed by the bottom plate 36 and the upper plate 37 of the base 30. In other words, by tilting the washer mechanism 50 in the horizontal direction X, the height dimension of the washer mechanism 50 is such that it can be accommodated in the internal space formed by the bottom plate 36 and the upper plate 37.

[0057] The portable toilet can be easily disassembled as shown in Figures 5 to 9. Therefore, the portable toilet can be transported more compactly by folding the base 30 in the height direction and packing the rod 52 with the handle 53-1 attached, the water supply unit 40, etc., thereby improving transport efficiency. In other words, efficient transport is possible and the toilet can be easily stored in a small space. When transporting the portable toilet, it is preferable to pack 10 excretion bags and 10 coagulants (not shown), which are equivalent to 10 toilet uses, and store them in the internal space of the base 30.

[0058] FIG. 11 is a perspective view showing the disassembled base 30 installed upside down. The base 30 has a maximum load capacity of approximately 100 kg, so when not in use as a portable toilet, it can be disassembled and installed upside down as shown in FIG. 11. This allows the base 30, which can be installed upside down, to withstand a load that can be used not only in emergencies but also as a step stool or chair at car campsites, etc. The base 30 can be washed entirely with water, making it hygienic and reusable. It can also be used as a multipurpose storage box, and can be used for various purposes not only in emergencies or hospitals, but also in everyday life.

[0059] Example 2 Next, a portable toilet with a manual washer according to a second embodiment will be described. FIG. 12 is an exploded view of the main components of a portable toilet 2 with a manual washer. The portable toilet 2 with a manual washer of this embodiment is provided with a seat 201 having an egg-shaped opening 201A in the center, a cylindrical portion 101A fitted into the egg-shaped opening 201A, and a seat 101 having a seat portion 101B extending in a bell shape from the cylindrical portion 101A, on a base 30 similar to that of the first embodiment. In this embodiment, the opening and closing mechanism of the seat 101 is omitted, and the structure is simpler and more space-saving in the height direction (so that it is thinner when folded). Note that the structure of the base 30 and the folding mechanism are the same as those of the first embodiment, and therefore description thereof will be omitted.

[0060] A washer mechanism 501 is attached to the back surface of the seat base 201. The structure of the washer mechanism 501 is the same as the washer mechanism 50 in the first embodiment except for the position change mechanism. The position change mechanism of the washer mechanism 501 is composed of a pair of (corresponding) engagement mechanisms provided on the seat base 201 and the plate 551, respectively. FIG. 13 is an explanatory diagram of the engagement mechanism. In this example, the engagement mechanism is composed of a guide rail 541 provided on the back surface of the seat base 201 and a protrusion 551A provided on the end of the plate 551. This engagement mechanism causes the washer mechanism 501 (plate 551) to hang down below the seat base 201 (supported in the use position) when the toilet is in use, and the plate 551 to be removed from the seat base 201 (moved to the retracted position) when the base part 30 is folded. By configuring plate 551 to be removable, it is no longer necessary to consider the bulk of plate 551 when folding base part 30, and base part 30 can be configured to be folded thinner.

[0061] Example 3 Next, a description will be given of a portable toilet with a manual washer according to a third embodiment. Fig. 14 is a perspective view of the portable toilet with a manual washer when in use. Fig. 15 is an explanatory diagram of a method for attaching a container for receiving excrement.

[0062] Portable toilet 3 with manual washer includes seat base 302 with an egg-shaped opening, base portion 302 formed as four legs extending vertically (downward) from the back surface of seat base 302, washer mechanism 551, lever 53, etc. In this example, seat base 302 is configured to also serve as a seat.

[0063] A pair of slide rails 91 are provided on the underside of the seat 302, and a container 92 for receiving excrement is detachably guided horizontally by these slide rails 91. In this example, a collapsible bucket is used as the container 92 for receiving excrement (FIG. 15).
