[Modes for carrying out the invention]

[0009] [Embodiment] The portable toilet 100 according to this embodiment will be described in detail below.

[0010] The portable toilet 100 according to this embodiment is a portable, simple toilet. The portable toilet 100 can be used, for example, during evacuation in the event of a disaster, while camping, or during traffic congestion. The portable toilet 100 according to this embodiment can store items inside and can be transformed into at least two types of usage modes, such as for adults or for infants (children). As shown in Figure 1, the portable toilet 100 according to this embodiment comprises a housing 10, a storage box 5 housed inside the housing 10, and a toilet seat 3 that rests on the housing 10. The portable toilet 100 also further comprises a toilet lid 4.

[0011] (Cabinet 10) The housing 10 is the part of the portable toilet 100 that supports the toilet seat 3. The housing 10 is formed in a hollow shape and has an opening on the upper surface of its peripheral wall. The toilet seat 3 is attached to the upper end surface of the peripheral wall of the housing 10. The housing 10 is configured to be separable into an upper section 1 and a lower section 2. Figure 2 shows a schematic perspective view of the housing 10, which is disassembled into an upper section 1 and a lower section 2. Referring to Figure 2, the upper section 1 has a circumferential wall (hereinafter referred to as the first circumferential wall 11), a flange (hereinafter referred to as the first flange 12) provided on the upper edge of the first circumferential wall 11, and a handle 13. The upper section 1 has an opening on the upper surface of the first circumferential wall 11. The first circumferential wall 11 and the first flange 12 of the upper section 1 are integrally formed by resin molding. The upper section 1 is made of synthetic resin. Examples of synthetic resins that form the upper section 1 include polyethylene, polyvinyl chloride, polyethylene terephthalate, polystyrene, polypropylene, and ABS resin. The synthetic resin that forms the upper section 1 may also include, for example, glass fiber and carbon fiber.

[0012] The first circumferential wall 11 is formed in a cylindrical shape. Openings are formed on the upper and lower end surfaces of the first circumferential wall 11. The first circumferential wall 11 is formed in a D-shape in plan view. The first circumferential wall 11 has a rear part (hereinafter, first rear part 111), a front part (hereinafter, first front part 112), and a pair of side parts (hereinafter, first side parts 113). The first rear part 111 is a portion that includes an outer surface facing rearward in a region behind the center in the front-rear direction in a plan view. The first front part 112 is a portion that includes an outer surface facing forward in a region in front of the center in the front-rear direction in a plan view. The first front part 112 according to this embodiment is formed in an arc shape in plan view. Each first side part 113 is a portion that connects the first front part 112 and the first rear part 111. The first side parts 113 face outward. The first peripheral wall 11 is not limited to a D-shape in plan view, but may also be formed in, for example, a square tube, a pentagonal tube, or a hexagonal tube.

[0013] A vertical rib portion (hereinafter referred to as the first vertical rib portion 114) is formed on the first circumferential wall 11. The first vertical rib portion 114 extends in the height direction on the first circumferential wall 11. In this embodiment, the first vertical rib portion 114 is formed on the first rear portion 111. As shown in Figure 3, the first vertical rib portion 114 is formed from a pair of upright pieces 115 that protrude inward from the first rear portion body (the portion of the first rear portion 111 other than the first vertical rib portion 114) and an inner plate 116 that connects the tips of the pair of upright pieces 115. The first vertical rib portion 114 is recessed from the outer circumferential surface of the first circumferential wall 11.

[0014] The lower end of the first circumferential wall 11 is configured to be attachable to the upper end of the lower divided body 2. As shown in Figure 3, the lower end of the first circumferential wall 11 has a mounting surface 117 and an internal fitting portion 118. The mounting surface 117 is formed at the lower end of the first circumferential wall 11 in the housing 10 and is configured to be mounted on the upper end surface of the lower divided body 2. The internal fitting portion 118 protrudes downward from the mounting surface 117 and fits into the inner circumferential surface of the opening of the lower divided body 2. Because the mounting surface 117 and the internal fitting portion 118 are formed at the lower end of the first circumferential wall 11, the housing 10 is stably supported by the lower divided body 2.

[0015] The first flange 12 protrudes outward from the outer peripheral edge at the upper end of the first peripheral wall 11. The first flange 12 is formed over the entire outer peripheral edge in the first peripheral wall 11. The first flange 12 is formed in an L-shaped cross section. The first flange 12 may be formed in a flat plate shape. By having the first flange 12, the rigidity of the first peripheral wall 11 of the housing 10 is increased.

[0016] The handle 13 is formed to lift the housing 10. The handle 13 protrudes outward from a part of the first flange 12. By hanging a finger on the handle 13, the user can easily lift the portable toilet 100.

[0017] The height of the upper divided body 1 may be 150 mm or more and 300 mm or less, may be 170 mm or more and 250 mm or less, or may be 200 mm or more and 230 mm or less. The "height" referred to here means the maximum height in the upper divided body 1. Thus, without using the lower divided body 2, the portable toilet 100 can be used in a small size mode by directly grounding the upper divided body 1 on the installation surface. For example, by setting the height of the toilet seat 3 with respect to the installation surface to the average height when used by infants, it can be used as a toilet for infants.

[0018] (Lower divided body 2) The lower divided body 2 can be disposed between the installation surface and the upper divided body 1. By disposing the lower divided body 2 between the upper divided body 1 and the installation surface, the portable toilet 100 can be used in a larger size mode than when using only the upper divided body 1. For example, by setting the height of the toilet seat 3 with respect to the installation surface to the average height when used by adults, it can be used as a toilet for adults.

[0019] The lower section 2 is formed in a container shape with an opening on its upper surface. As shown in Figure 2, the lower section 2 has a peripheral wall (hereinafter referred to as the second peripheral wall 21), a bottom wall 22, and a flange (hereinafter referred to as the second flange 23) provided on the upper edge of the second peripheral wall 21. The bottom wall 22, the second peripheral wall 21, and the second flange 23 of the lower section 2 are integrally formed by resin molding. The lower section 2 is made of synthetic resin. Examples of synthetic resins that form the lower section 2 include polyethylene, polyvinyl chloride, polyethylene terephthalate, polystyrene, polypropylene, and ABS resin. The synthetic resin that forms the lower section 2 may also contain, for example, glass fibers and carbon fibers. The material of the lower section 2 may be the same as that of the upper section 1, or it may be a different material.

[0020] The bottom wall 22 extends parallel to the installation surface. The bottom wall 22 is formed in a flat plate shape. As shown in Figure 3, the bottom wall 22 has a first main surface 221 facing downwards and a second main surface 222 facing upwards. From the perspective of the bottom wall 22, the first main surface 221 is located on the opposite side of the second main surface 222.

[0021] The second circumferential wall 21 extends upward from the outer peripheral edge of the bottom wall 22. The second circumferential wall 21 is formed in a cylindrical shape. That is, the lower divided body 2 is formed in a bottomed cylindrical shape. An opening surface is formed on the upper end surface of the second circumferential wall 21. The second circumferential wall 21 is formed in a D shape in plan view. The second circumferential wall 21 has a rear part (hereinafter, second rear part 211), a front part (hereinafter, second front part 212), and a pair of side parts (hereinafter, second side parts 213). The second rear part 211 is a portion that includes a surface facing backward in a region behind the center in the front-rear direction in a plan view. The second front part 212 is a portion that includes a surface facing forward in a region in front of the center in the front-rear direction in a plan view. The second front part 212 according to this embodiment is formed in an arc shape in plan view. Each second side portion 213 is a part that connects the second front portion 212 and the second rear portion 211. The second side portions 213 face outward. The first peripheral wall 11 is not limited to a D shape in plan view, but may be formed in, for example, a square tube, a pentagonal tube, or a hexagonal tube.

[0022] A longitudinal rib portion (hereinafter referred to as the second longitudinal rib portion 214) is formed on the second peripheral wall 21. The second longitudinal rib portion 214 extends in the height direction on the second peripheral wall 21. The second longitudinal rib portion 214 is positioned to be continuous in the vertical direction with respect to the first longitudinal rib portion 114. In this embodiment, the second longitudinal rib portion 214 is formed on the rear. The second longitudinal rib portion 214 is formed from a pair of upright pieces 215 that protrude inward from the second rear body (the portion of the second rear 211 other than the second longitudinal rib portion 214) and an inner plate 216 that connects the tips of the pair of upright pieces 215. The second longitudinal rib portion 214 is recessed from the outer peripheral surface of the first peripheral wall 11.

[0023] When the lower section 2 is attached to the lower end of the upper section 1, the second longitudinal rib section 214 and the first longitudinal rib section 114 are aligned in the height direction. "The second longitudinal rib section 214 and the first longitudinal rib section 114 are aligned in the height direction" means that, in a plan view, at least a part of the second longitudinal rib section 214 overlaps with the first longitudinal rib section 114. In this embodiment, the upright pieces 115 of the first longitudinal rib section 114 and the upright pieces 215 of the second longitudinal rib section 214 are aligned in the height direction. As a result, the second longitudinal rib section 214 can effectively receive the load applied to the first longitudinal rib section 114.

[0024] The second flange 23 protrudes outward from the outer peripheral edge of the upper end of the second peripheral wall 21. The second flange 23 is formed around the entire circumference of the outer peripheral edge of the second peripheral wall 21. The lower segment 2 has increased rigidity of the second peripheral wall 21 due to the presence of the second flange 23.

[0025] The height of the lower section 2 may be between 150 mm and 300 mm, between 170 mm and 250 mm, or between 200 mm and 230 mm. Here, "height" refers to the maximum height of the upper section 1. This allows for the formation of larger-sized toilets. The height of the lower section 2 may be the same as the height of the upper section 1, or it may be a different height.

[0026] As shown in Figure 2, the lower section 2 has a connecting plate 24 that connects the first peripheral wall 11 of the upper section 1 and the second peripheral wall 21 of the lower section 2. In a plan view, an insertion hole 25 is formed at the point where a straight line passing through the center of the lower section 2 and the connecting plate 24 intersects with the first peripheral wall 11. In other words, in a plan view, the insertion hole 25 is formed on the part of the lower section 2 opposite to the connecting plate 24. Also, a locking piece 14 is formed at the lower end of the first peripheral wall 11 of the upper section 1, which is inserted into the insertion hole 25. The upper section 1 and the lower section 2 are connected by inserting the locking piece 14 into the insertion hole 25 and then securing the connecting plate 24. This allows the lower section 2 to be positioned relative to the upper section 1, and the lower section 2 can be lifted together with the upper section 1 simply by lifting the upper section 1. The connecting plate 24 has a connecting plate body 241 and a plurality of locking claws 242.

[0027] Referring to Figure 4, the connecting plate body 241 is rotatably attached to the second peripheral wall 21 of the lower segment 2. The axis of rotation of the connecting plate body 241 is parallel to the opening surface. In this embodiment, the axis of rotation of the connecting plate body 241 is parallel to the horizontal surface. The axis of rotation of the connecting plate body 241 is positioned along the outer surface of the second rear portion 211. The connecting plate body 241 is formed in a flat plate shape. The connecting plate body 241 includes a first main surface 243 and a second main surface 244 located on the opposite side from the first main surface 243.

[0028] The locking claw 242 protrudes from the first main surface 243 of the connecting plate body 241. When the connecting plate body 241 is rotated around the axis of rotation, and the first main surface 243 faces the first rear portion 111 of the upper divided body 1, the locking claw 242 hooks onto the locking portion 119 formed on the upper divided body 1. In this way, the connecting plate 24 connects the first peripheral wall 11 of the upper divided body 1 and the second peripheral wall 21 of the lower divided body 2.

[0029] When the locking portion and the locking claw 242 of the connecting plate 24 are released, the connecting plate body 241 rotates around the axis of rotation until the second main surface 244 faces the second rear portion 211 of the lower divided body 2. In this state, when the lower divided body 2 is housed inside the upper divided body 1, the tip surface of the locking claw 242 faces the inner circumferential surface of the upper divided body 1, as shown in Figure 5. This reduces the looseness of the lower divided body 2 relative to the upper divided body 1 when the lower divided body 2 is housed inside the upper divided body 1.

[0030] (Storage box 5) The storage box 5 is removably stored inside the housing 10. The storage box 5 can store items. Examples of items that can be stored include disaster prevention supplies and toilet supplies. Examples of disaster prevention supplies include drinking water, whistles, warm clothing, slippers, first-aid kits, adhesive tape, work gloves, portable hand warmers, lighters, matches, and towels. Examples of toilet supplies include toilet paper, disposal bags 6, and solidifying agents. However, the items that can be stored are not limited to disaster prevention supplies and toilet supplies.

[0031] Here, Figure 6 shows a schematic perspective view of the disassembled storage box 5. Figure 7 shows a schematic cross-sectional view of the storage box 5 housed inside the housing 10. Figure 8 shows a schematic plan view of the storage box 5 housed inside the lower divided body 2. Referring to Figure 6, the storage box 5 has a container-shaped box body 51 with an opening on its top surface, and a lid 52 that closes the opening on the box body 51.

[0032] The box body 51 has a bottom plate 511 and side plates 512. The box body 51 has an opening on the upper surface of the side plates 512. The bottom plate 511 and the side plates 512 of the box body 51 are integrally formed by resin molding. In this embodiment, the box body 51 is made of synthetic resin. Examples of synthetic resins that form the box body 51 include polyethylene, polyvinyl chloride, polyethylene terephthalate, polystyrene, polypropylene, and ABS resin. The synthetic resin that forms the box body 51 may also contain, for example, glass fibers and carbon fibers.

[0033] The bottom plate 511 is formed in a flat shape. The upper main surface of the bottom plate 511 (the top surface of the bottom plate 511) faces the storage space. The lower main surface of the bottom plate 511 (the bottom surface of the bottom plate 511) rests on the second main surface 222 of the bottom wall 22 in the lower divided body 2, as shown in Figure 7. Ribs may be formed on the bottom surface of the bottom plate 511 along the outer edge of the bottom plate 511. That is, the ribs may be in contact with the second main surface 222 of the bottom wall, or the entire bottom surface of the bottom plate 511, which does not have ribs, may be in contact with it.

[0034] The side plate 512 is formed to rise from the bottom plate 511. The side plate 512 is formed in a cylindrical shape and surrounds the storage space in a plan view. The side plate 512 is formed along the second peripheral wall 21 of the lower divided body 2 in the housing 10. That is, in a plan view, the outer shape of the side plate 512 is formed to be substantially the same as the inner peripheral surface of the lower divided body 2.

[0035] As shown in Figure 6, the side panel 512 has a side panel body 513 and a pair of side panel recesses 514. The side panel body 513 is the main part of the side panel 512 and is formed along the second peripheral wall 21. The side panel recesses 514 are recesses in the side panel body 513 toward the inside of the storage box 5 in a plan view. In the storage box 5 according to this embodiment, the pair of side panel recesses 514 are formed in a region corresponding to the central part in the front-rear direction. The side panel recesses 514 are formed along the entire length in the vertical direction of the side panel 512.

[0036] As shown in Figure 7, at least a portion of the side plate 512 may be close to the inner surface of the second peripheral wall 21. The side plate 512 according to this embodiment has a protrusion 515, the tip of which is close to the inner surface of the second peripheral wall 21. The protrusion 515 is formed at the upper end of the side plate 512. The proximity of the tip of the protrusion 515 to the inner surface of the second peripheral wall 21 reduces rattling of the storage box 5 housed in the housing 10 during transport. In this disclosure, "close" means being close to the object, and may be in contact with it or slightly separated. If it is separated from the object, it falls under the category of "close" if the gap is 1.0 times or less the thickness of the side plate 512.

[0037] Referring to Figure 6, the lid 52 is removably attached to the lid body 521 so as to close the opening of the box body 51. The lid 52 is formed in a plate shape. The lid 52 has a lid body 521 that rests on the upper end of the side plate 512 and a hanging piece 522 that protrudes downward along the outer edge of the lid body 521. A handle 524 is formed in the center of the lid body 521. The handle 524 is recessed from the top surface of the lid 52.

[0038] In this embodiment, the lid 52 is made of synthetic resin. Examples of synthetic resins that form the lid 52 include polyethylene, polyvinyl chloride, polyethylene terephthalate, polystyrene, polypropylene, and ABS resin. The synthetic resin that forms the lid 52 may also contain, for example, glass fibers and carbon fibers.

[0039] A pair of recesses 523 are formed on the outer edge of the lid 52 at positions corresponding to the side plate recesses 514. In plan view, the recesses 523 are formed in the same shape as the side plate recesses 514. As shown in Figure 8, the space S1 defined by the second peripheral wall 21 of the housing 10, the side plate recesses 514 of the side plate 512, and the recesses 523 of the lid 52 is open upward. Even though the side plate 512 is formed along the second peripheral wall 21 in the storage box 5, the user can easily lift the storage box 5 and remove it from the housing by inserting their fingers into the space S1.

[0040] As shown in Figure 7, a disposal bag 6 may be installed inside the housing 10. The opening edge of the disposal bag 6 is spread open and folded back at the opening edge of the housing 10, and sandwiched between the housing 10 and the toilet seat 3. In other words, the disposal bag 6 is attached to the housing so that its opening faces the opening of the toilet seat 3. At this time, the disposal bag 6 is supported from below by the lid 52. This allows the use of a relatively small disposal bag 6. Also, the lid 52 may be formed larger than the opening of the toilet seat 3 in a plan view. This reduces the risk of waste falling out of the lid 52 when it is contained in the disposal bag 6 during use.

[0041] The storage box 5 is housed inside the lower section 2. When the storage box 5 is housed inside the lower section 2, the lid 52 is positioned below the upper end of the lower section 2. In this state, as shown in Figure 9, the lower section 2 can be housed inside the upper section 1. This allows the lower section 2 to be transported while housed inside the upper section 1.

[0042] Referring to Figure 9, when the lower section 2 is housed within the upper section 1, the upper end of the lower section 2 is located below the toilet seat 3. In this embodiment, when the lower section 2 is housed within the upper section 1, the upper end of the lower section 2 is located between the upper end of the upper section 1 and the toilet seat 3 in the vertical direction. At this time, the upper end of the lower section 2 is covered by the toilet seat 3. Also, the lid 52 of the storage box 5 is located below the toilet seat 3. Since the lid 52 is larger than the opening of the toilet seat 3, when the toilet seat 3 is installed, the lid 52 does not pass through the opening.

[0043] (Toilet seat 3) The toilet seat 3 is attached to the housing 10 along the opening surface. The toilet seat 3 has an opening in the center. The toilet seat 3 is an O-shaped toilet seat 3. However, the opening of the toilet seat 3 may be a U-shaped toilet seat 3. The toilet seat 3 is removably attached to the periphery of the opening of the housing 10.

[0044] The toilet seat 3 is made of synthetic resin. Examples of synthetic resins that form the toilet seat 3 include polyethylene, polyvinyl chloride, polyethylene terephthalate, polystyrene, polypropylene, and ABS resin. The synthetic resin that forms the toilet seat 3 may also contain, for example, glass fiber or carbon fiber. The material of the toilet seat 3 may be the same as that of the housing 10 and the lower segment 2, or it may be a different material.

[0045] As shown in Figure 1, the toilet seat 3 has a hinge portion 31 to which the toilet lid 4 is rotatably attached. The hinge portion 31 is located on the toilet seat 3 at a position corresponding to the rear of the housing 10.

[0046] (Toilet lid 4) The toilet lid 4 is attached so as to cover the toilet lid 4. The toilet lid 4 is rotatably attached to the toilet seat 3 by a hinge portion 31. The axis of rotation of the toilet lid 4 is parallel to the opening surface of the housing 10, and in this embodiment, it is parallel to the horizontal surface. The toilet lid 4 can close the opening in the center of the toilet seat 3.

[0047] (How to use) The portable toilet 100 according to this embodiment can be transformed between a storage and transport configuration and a usage configuration. Furthermore, the usage configuration can be transformed into a first configuration for adult use and a second configuration for infant (child) use.

[0048] In the storage configuration, as shown in Figure 9, the storage box 5 containing the items to be stored is placed inside the lower section 2, and the lower section 2 is placed inside the upper section 1. In this state, the toilet seat 3 and toilet lid 4 are attached. This makes the portable toilet 100 compact with the storage box 5 stored inside, making it easy to transport.

[0049] In the first configuration, as shown in Figure 1, the lower section 2 is attached to the lower end of the upper section 1. The lower section 2 and the upper section 1 are connected using a connecting plate 24. After this, the disposal bag 6 is installed inside the housing 10. This creates a simple toilet that can be used by adults. Since the disposal bag 6 can be installed while the storage box 5 is still stored inside the lower section 2, the transformation from the storage configuration to the usage configuration can be done quickly and easily.

[0050] In the second form, the lower section 2 and storage box 5 can be removed, and the upper section 1, toilet seat 3, and toilet lid 4 can be used without using the lower section 2. The lower section 2 can be set aside with the storage box 5 still inside. This allows for easy transformation to the second form when the portable toilet 100 in the first form is too large. Since the storage box 5 can be stored inside the lower section 2, the transformation can be done quickly and easily simply by removing the lower section 2 from the housing 10.

[0051] [Differentiation] The embodiments described above are merely one of many embodiments of this disclosure. The embodiments can be modified in various ways depending on the design, etc., as long as they achieve the objectives of this disclosure. The following lists some modifications of the embodiments. The modifications described below can be combined and applied as appropriate.

[0052] In the above embodiment, the connecting plate 24 is provided on the housing 10, but it may also be rotatably mounted to the peripheral wall of the housing 10.

[0053] In the above embodiment, the side plate 512 of the storage box 5 was in close proximity to the second peripheral wall 21 of the lower divided body 2 in a plan view, but the side plate 512 does not necessarily have to be in close proximity to the second peripheral wall 21.

[0054] In the above embodiment, the housing 10 is configured to be separable into an upper split body 1 and a lower split body 2, but the housing 10 may be configured not to be separable.

[0055] [summary] As described above, the portable toilet 100 according to the first embodiment comprises a housing 10 having an opening on the upper surface of its peripheral wall, a toilet seat 3 attached to the housing 10 along the opening, and a storage box 5 that is removably housed inside the housing 10. According to this embodiment, since the items to be stored can be stored inside the storage box 5, psychological resistance on the part of the user can be reduced.

[0056] In the portable toilet 100 according to the second embodiment, the storage box 5, in the first embodiment, has a container-shaped box body 51 having an opening on its top surface, and a lid 52 that closes the opening on the box body 51.
