Description

Technical Field

[0001] The present invention relates to a portable toilet with a manual washer that can be used as a disaster prevention toilet when water and electricity are unavailable during emergencies, or can be prepared beside a bed in a hospital or a nursing facility.

Background Art

[0002] A portable toilet is used as a portable and simple toilet, and it is required that the installation area and height dimensions enable it to be used in a comfortable posture without burdening the legs and waist, and to improve the sitting comfort. Also, a portable toilet is used together with a waste bag and a coagulant.

[0003] The waste bag should have high airtightness and a long expiration date, and the coagulant should be good at firmly solidifying excrement and suppressing odor with a deodorizing effect. Furthermore, when not used as a portable toilet, it is desirable that it can be used in various scenes such as a multi-purpose storage box, a step, and a chair.

[0004] Preferably, a portable toilet is equipped with a washer using a nozzle. And it is preferable that the switching of the necessity of bidet washing can be made by manually moving the nozzle without using external power such as electricity. However, rotating the nozzle substantially horizontally increases the nozzle installation space, so the portable toilet has to be enlarged.

[0005] Therefore, in order to reduce the installation area of a portable toilet with a washer, a lever rotatable around an axis on the side surface of the pedestal of the portable toilet in a vertical plane in the height direction is provided, and it is known that the washer nozzle rotates together with the rotation of the lever, as described in Patent Documents 1 and 2.

[0024] Hereinafter, a specific example of this embodiment will be described with reference to the drawings. Figure 1 shows a perspective view of the portable toilet with a manual washer according to Embodiment 1 of the present invention when it is in use. The portable toilet requires a predetermined height dimension (height in the Y direction) for the base portion 30 so that the user can sit on the seat 10 in a comfortable posture and so that the excrement can be temporarily contained.

[0025] However, since portable toilets are portable, simple toilets, it is necessary to consider miniaturization and ease of handling when transporting them. In this embodiment, the base portion 30 is foldable in the height direction Y, and the washer mechanism 50 is configured to be foldable (can be collapsed) in the horizontal direction X by a position change mechanism consisting of hinges or the like.

[0026] In Figure 1, the seat 10 on which the user sits has an egg-shaped opening in the center, with a rounded edge for comfortable seating, and projections 11 and 12 at the rear. The seat base 20, which also has an egg-shaped opening similar to the seat 10, fits into and secures the base 30 as a lid. The seat base 20 is also provided with seat hinges 21 and 22 that fit into the seat 10 via projections 11 and 12.

[0027] The seat 10 is mounted on the seat base 20 so as to be rotatable around its rear end to an angle beyond the vertical position from the horizontal position, as shown by arrow R, with the seat hinges 21 and 22 as the axis of rotation, and is also removable. In this embodiment, it is preferable to provide a top cover that covers the seat 10 (not shown) using the seat hinges 21 and 22, and is rotatable in the same way as the seat 10.

[0028] The portable toilet comprises a water supply unit 40 that is fixed to and detachable from the base unit 30 or seating platform 20, and a washer mechanism 50 that is mounted on the seating platform 20 and has a nozzle 51 and a washing hole 51-1 that is rotatable in a vertical plane (in the vertical direction). The lever 53 is provided at the right end of the base unit 30 when assembled.

[0029] The rod 52 is fixed to the lower part of the lever 53 and can be connected to the washer mechanism 50 by passing through the hole 34-1 in the upper right plate 34 of the base portion 30. A spherical grip 53-1 is attached to the upper end of the lever 53. In Figure 1, the lever 53 is positioned on the right side, but it can also be positioned 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 spray liquid (specifically, hot water and 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., during defecation, the washer mechanism 50 retracts the nozzle 51 and the cleaning hole 51-1 to the rear so that they do not get in the way.

[0031] The nozzle 51 is moved by manually rotating the lever 53 along a vertical plane via the rod 52 and the washer mechanism 50. Thus, a manually operated portable toilet that requires no external power is realized. The arrow S indicates the direction in which the lever 53 is rotated (clockwise when viewed from the right) during posterior washing.

[0032] The liquid (hot water, water, etc.) supplied to the nozzle 51 can be stored in the water supply unit 40 in amounts greater than a predetermined quantity. This predetermined quantity is determined by the spray speed from the cleaning hole 51-1, the spray volume per unit time, and the spray duration, which will nearly fill a 2-liter PET bottle 41. The position of the PET bottle 41 is determined by inverting the container and raising its outlet (cap) 40-50 cm or more above the position of the nozzle 51 or cleaning hole 51-1, utilizing the resulting water head.

[0033] Furthermore, the PET bottle 41 is not limited to a configuration that obtains injection pressure from the positional head; it may also be a polyethylene pressurized container that is pressurized with a manual pump and fixed near the seating base 20. In this case, the manual pump would be withdrawn from the pressurized container beforehand and pressurized to compress the air inside the container.

[0034] In Figure 1, the PET bottle 41 is located at the left rear and is held in place by a fixing device 46 fixed to one end of the seating base 20, and an annular receiving device 43 connected to the fixing device 46. The water supply tube 45 and the PET bottle 41 are connected using a flexible connecting hose with a connector 44 shaped to match the cap portion of the PET bottle 41. The bottom surface of the PET bottle 41 may have an opening 42 for filling with water and venting air. It is preferable to cover this opening 42 so that water does not leak even when the bottle is turned upside down.

[0035] The base 30 is fitted into or secured to the seating platform 20 by screws, and has a maximum load capacity of 100 kg, making it strong enough to withstand the weight of a user, even for larger individuals. The height of the base 30 is 40-50 cm and the depth is 50-60 cm, allowing for a comfortable posture without straining the legs or waist. When not used as a portable toilet, the base 30 can be used as a container box, step stool, chair, etc.

[0036] The base section 30 has a front plate 31 and a rear plate 32 attached to the bottom plate 36 in a foldable manner, and in Figure 1, it is assembled upright on the bottom plate 36 and seating base 20. On the right side of the base section 30, the upper right plate 34 and the lower right plate 33 are attached to the bottom plate 36 and are foldable on an intermediate shaft 35. Although not shown, the left side of the base section 30 is the same as the right side.

[0037] The internal space of the assembled base section 30 is where the waste bag and coagulant (not shown) are installed. The coagulant is a highly airtight, moisture-proof aluminum bag. The waste bag used for processing the waste is made of high-density polyethylene, which is durable and prevents odor leakage.

[0038] Figure 1 shows the assembly upright on the base plate 36 and seating base 20, similar to the front and rear views. The base 30 is preferably made of a general-purpose resin such as polypropylene, which has relatively high strength, excellent chemical resistance (including acids and alkalis), and no moisture absorption.

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

[0040] The washer mechanism 50 includes a position-changing mechanism that supports the plate 55 so that it can move between a usage position and a retracted position. In Embodiment 1, the position-changing mechanism is formed from a flange 54 and a hinge 56. The flange 54 is fixed to the back surface of the seating base 20 and is connected to the plate 55 via the hinge 56, suspending the main part of the washer mechanism 50 (in a vertically mounted state). Figure 2 shows the portable toilet in use, i.e., with the plate 55 pointed to the usage position. The plate 55 rotates around the hinge 56 relative to the seating base 20 as indicated by arrow T, and is positioned vertically (height direction Y).

[0041] The receiving portion 58 is fixed to the left side of the lower end of the plate 55, the receiving portion 57 is fixed to the right side, and the hollow shaft 60 is rotatably supported by the receiving portions 57 and 58. The rod 52 is inserted into the receiving portions 57 and 58 from the direction of arrow U and fixed to the hollow shaft 60 with a fixing pin 61, integrating them together. As a result, the hollow shaft 60 rotates in sync with the lever 53, providing a firm and responsive feel.

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

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

[0044] Figures 3 and 4 are left side views of the washer mechanism 50 as seen from the left. Figure 3 shows the nozzle 51 and the cleaning hole 51-1 in the retracted position, and Figure 4 shows the lever 53 being 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 projection 55-1 on a plate 55.

[0045] The spring 65 is located between a pin 55-2 embedded in the plate 55 and a stay pin 59-1 that is erected on the stay 59. The opening / closing lever 62-2 is connected to the stay 59 as a link mechanism by the stay pin 59-1. Figure 3 shows the opening / closing valve 62-1 in the closed position.

[0046] During rear washing, the lever 53 is rotated counterclockwise in the view of the drawings as shown in Figures 3 and 4, against the biasing force of the spring 65. This causes the arc-shaped nozzle 51 and washing hole 51-1 to rotate around the hollow shaft 60 to reach their predetermined positions. The opening / closing lever 62-2 is connected to the stay pin 59-1, and similarly rotates to open the opening / closing valve 62-1.

[0047] Since the nozzle 51 moves in a circular motion around the hollow shaft 60, lowering the position of the hollow shaft 60 reduces the space it occupies when retracting backward, thus reducing the rearward depth dimension of the base 30. In addition, the rotation angle of the lever 53 becomes smaller if the position of the hollow shaft 60 is lower, improving ease of use.

[0048] However, since the plate 55 increases in size as the position of the hollow shaft 60 is lowered, the washer mechanism 50 had to be made larger in the height direction. The base 30 of the portable toilet should ideally be foldable for transport purposes, but the height of the washer mechanism 50 was an obstacle.

[0049] In this embodiment, the foldable base portion 30 is partially detachable to make effective use of it, and the washer mechanism 50 is configured to be able to be tilted horizontally in the X direction by a position change mechanism. Figure 5 is a front view showing a partial cross-section corresponding to Figure 2, which shows the disassembly procedure of the washer mechanism 50. When disassembling for transport, first, the fixing pin 61 is pulled out in the direction of arrow W, and the engagement between the hollow shaft 60 and the rod 52 is released. Next, the rod 52 and lever 53 are pulled out in the direction of arrow V.

[0050] Figure 6 is a front view showing a partial cross-section corresponding to Figure 2, illustrating the washer mechanism 50 in a retracted position (tilted horizontally in the X direction). The plate 55 rotates around the hinge 56 as indicated by arrow P and is tilted horizontally in the X direction. This makes it possible to maintain a seemingly constant thickness and height dimension for the washer mechanism 50, regardless of the position of the hollow shaft 60.

[0051] Next, disassembly for transport is performed by removing the seating base 20 upward from the base portion 30. Figure 7 shows a perspective view of the seating base 20 after it has been removed. The seating base 20 is removed in the direction of arrow Q by releasing the screws or other fasteners that are fitted or attached to the upper plate 37 of the base portion 30. The lower right plate 33 and the lower left plate 73 are foldable and fitted into the bottom plate 36 on the inside of the base portion 30.

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

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

[0054] First, the front plate 31 and rear plate 32 are folded down as shown by arrow F in Figure 8 until they fit into the inner space of the bottom plate 36. Then, the lower right plate 33, lower left plate 73, upper right plate 34, and upper left plate 74 are folded inward as shown by 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 horizontally in the X direction as described in Figure 6, making the height dimension appear smaller, and the base portion 30 is folded in the height direction as described in Figures 8 and 9, making it possible to make it thin as shown in Figure 10.

[0056] In this state, the washer mechanism 50 is tilted horizontally in the X direction as explained in Figure 6, so it can be housed in the internal space formed by the bottom plate 36 and the top plate 37 of the base portion 30. In other words, by tilting the washer mechanism 50 horizontally in the X direction, it has dimensions in the height direction that allow it to be housed in the internal space formed by the bottom plate 36 and the top plate 37.

[0057] The portable toilet can be easily disassembled as shown in Figures 5 to 9. Therefore, the portable toilet can be made smaller by folding the base 30 in the height direction and including the rod 52 with the handle 53-1 attached, the water supply unit 40, etc., thereby improving transport efficiency. In other words, it can be transported efficiently and easily stored in narrow spaces. When transporting, it is preferable to include 10 waste bags equivalent to 10 toilet uses and 10 solidifying agents (not shown) which are stored in the internal space of the base 30.

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

[0059] (Example 2) Next, the portable toilet with a manual washer of Example 2 will be described. Figure 12 is an exploded view of the main parts of the portable toilet with a manual washer 2. The portable toilet with a manual washer 2 of this example is equipped with a seating platform 201 having an egg-shaped opening 201A in the center, and a seat 101 having a cylindrical part 101A that fits into the egg-shaped opening 201A, and a seating part 101B that spreads out in a bell shape from the cylindrical part 101A, on a base 30 similar to that of Example 1. In this example, the opening and closing mechanism of the seat 101 is omitted, and it is configured to be simpler and to save space in the height direction (to become thinner when folded). Note that the structure of the base 30 and the folding mechanism are the same as in Example 1, so a description will be omitted.

[0060] A washer mechanism 501 is attached to the underside of the seat base 201. The structure of the washer mechanism 501 is the same as that of the washer mechanism 50 in Embodiment 1, except for the position change mechanism. The position change mechanism of the washer mechanism 501 consists of a pair of (corresponding) engagement mechanisms provided on the seat base 201 and the plate 551, respectively. Figure 13 is an explanatory diagram of the engagement mechanism. In this example, the engagement mechanism consists of a guide rail 541 provided on the underside of the seat base 201 and a projection 551A provided on the end of the plate 551. With this engagement mechanism, the washer mechanism 501 (plate 551) is suspended below the seat base 201 (supported in the usage position) when the toilet is in use, and when the base portion 30 is folded, the plate 551 is removed from the seat base 201 (moved to the retracted position). By making the plate 551 removable, it is no longer necessary to consider the bulk of the plate 551 when folding the base portion 30, making it possible to configure the base portion 30 to fold more thinly.

[0061] (Example 3) Next, we will describe the portable toilet with a manual washer according to Example 3. Figure 14 is a perspective view of the portable toilet with a manual washer in use. Figure 15 is an explanatory diagram of how to attach the container for receiving waste.

[0062] The manual portable toilet 3 with a washer comprises a seating platform 302 having an egg-shaped opening, a base portion 302 formed as four legs extending vertically (downward) from the underside of the seating platform 302, a washer mechanism 551, and a lever 53, etc. In this example, the seating platform 302 is configured to also serve as a seat.

[0063] A pair of slide rails 91 are provided on the underside of the seating base 302, and these slide rails 91 guide the container 92 for receiving waste to be attached and detached horizontally. In this example, a folding bucket is used as the container 92 for receiving waste (Figure 15).

[0064] When folding the base 302, the rod is removed from the washer mechanism 551, the plate 551 is removed from the base (moved to the retracted position), and the base 302 is folded in the height direction by tilting it down using a hinge (not shown) provided at the joint between the seating base 302 and the base 302, allowing the entire unit to be stored compactly.
