[Technical Field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates to portable toilets and methods of using flush toilets. [Background technology]

[0002] Patent Document 1 discloses a portable toilet device that can be installed in a living space other than a toilet room. This portable toilet device has multiple legs on the bottom of the toilet body, and the toilet body is supported by the legs and is not fixed to the floor, so it can be easily moved. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-058823 Summary of the Invention [Problem to be solved by the invention]

[0004] When a user is able to walk independently but finds it difficult to climb the stairs to the floor where the toilet is located, a closet facing the bedroom may be converted into a toilet. However, if the user becomes unable to walk independently and is no longer able to reach the converted toilet, a new portable toilet will have to be installed next to the bed, resulting in the conversion being wasted. For this reason, it is conceivable to install the toilet device described in Patent Document 1 in a closet facing the bedroom and move it from the closet to the side of the bed when the user's physical ability declines. However, because the device described in Patent Document 1 is designed to be connected to an existing hand washing area with a washbasin, it is difficult to apply to bedrooms in private homes. Furthermore, because the toilet device described in Patent Document 1 is not fixed to the floor, it is prone to instability and there is a risk of it tipping over.

[0005] The present disclosure has been made to solve at least one of the above problems, and aims to provide a technology that can flexibly respond to the user's level of physical ability and makes the toilet less likely to tip over without fixing the toilet body to the floor. [Means for solving the problem]

[0006] The portable toilet according to the first disclosure comprises a base body that can be moved with a flush toilet bowl placed on it, and a back panel that can be attached and detached perpendicular to the base body, is wider than the base body, and comes into contact with the floor surface.

[0007] In the method of using a flush toilet according to the second disclosure, a flush toilet that has been installed and used in a space facing a room in which a bed is installed is moved to the side of the bed and used. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] <Embodiment 1> A first embodiment of a mobile toilet 1 according to the present disclosure will be described with reference to the drawings. In the following description, the front-to-back direction, left-to-right direction (width direction), and up-to-down direction of the mobile toilet 1 are defined as directions seen from a user normally seated on a flush toilet 10 placed on a toilet movement base 3. Here, a user is someone who uses the flush toilet 10 for the purpose of excretion. The X-axis, Y-axis, and Z-axis shown in each drawing represent the front-to-back direction, left-to-right direction, and up-to-down direction, respectively. The positive directions of the X-axis, Y-axis, and Z-axis are forward, left, and upward, respectively.

[0010] The mobile toilet 1 according to the first embodiment is installed in a closet C, a space facing a living room Br in which a bed B is installed, with the flush toilet 10 and pulverization pressure pump 30 mounted on the base body 50 (see FIG. 5). The closet C has been remodeled in advance so that it can be used as a toilet room. The toilet moving base 3, the flush toilet 10, and the pulverization pressure pump 30 are components of the mobile toilet 1. If the user is able to walk, the user walks to the mobile toilet 1 installed in the closet C that has been remodeled into a toilet room. If the user has difficulty walking, the mobile toilet 1, with the flush toilet 10 and pulverization pressure pump 30 mounted on the base body 50, is moved to the side of the bed B (see FIG. 5). This allows the user to transfer from the bed B to the closet C that has been remodeled into a toilet room to the flush toilet 10 without walking.

[0011] [Configuration of toilet moving base] As shown in FIG. 1, the toilet moving base 3 includes a base body 50, a back panel 51, a pair of support parts 52, a pair of wheels 53, and a pair of handles .

[0012] [Base body configuration] The base body 50 is flat. To facilitate the easy installation of a commercially available flush toilet, the base body 50 is preferably made of wood, such as solid wood or plywood. The base body 50 may also be made of metal or synthetic resin, and may further include a frame made of metal pipes or the like. The base body 50 is placed on the floor surface F with its thickness facing up and down (see Figure 2). For example, the base body 50 has a thickness of 50 mm or less. By setting the thickness of the base body 50 to this dimension, the height of the flush toilet 10 seat can be made closer to the height of the seat of the bed B or wheelchair. This allows the user to smoothly transfer from the bed B or wheelchair to the flush toilet 10 of the mobile toilet 1 when the mobile toilet 1 is moved next to the bed B. If the base body 50 has a thickness of 50 mm or more, the toilet seat may be positioned too high, making it difficult to use, so the base body 50 preferably has a thickness of 50 mm or less. The base body 50 is long in the front-to-rear direction, and its front end is curved so that it bulges forward. The curve of the front end of the base body 50 is formed to follow the outer shape of the front end of the bottom surface of the flush toilet 10. When viewed from above, the base body 50 has a bullet shape. The outer dimensions of the base body 50 are the same as those of the bottom surface of the flush toilet 10, or slightly larger than those of the bottom surface of the flush toilet 10. Specifically, it is preferable to set the outer dimensions of the base body 50 so that they are larger than the upper limit of the design tolerance of the toilet body 10A of the flush toilet 10. Furthermore, taking into consideration the design tolerance of the flush toilet 10, it is preferable to set the upper limit of the design tolerance of the toilet body 10A to be about 50 mm larger, ensuring the necessary dimensions without excessively expanding the external dimensions of the base body 50. This is expected to have the effect of making it less likely for the base body 50 to get caught in the doorway of the closet C when the portable toilet 1 is moved from the closet C.

[0013] The base body 50 is provided with two pairs of connecting members 50A arranged side by side in the left-right direction. For example, the connecting members 50A are formed by bending a strip-shaped metal plate into an L-shape. Each connecting member 50A has a lying portion 50C forming one side of the L-shape and an upright portion 50D forming the other side of the L-shape. The pair of connecting members 50A are fixed to the base body 50 with wood screws, with the upright portions 50D facing each other with a space between them in the front-to-rear direction, and with the lying portions 50C in surface contact with the upper surface of the base body 50. Each upright portion 50D has a through-hole 50B formed therethrough in the plate thickness direction. When sandwiching and fixing the back panel 51 between the opposing upright portions 50D, it is desirable to make it easy to perform the fixing work from the front.

[0014] [Back panel configuration] The back panel 51 is flat and has a thickness oriented in the front-to-rear direction. The back panel 51 is preferably made of solid wood or plywood, similar to the base body 50. The left-right (width) dimension of the back panel 51 is greater than the left-right (width) dimension of the base body 50. In other words, the back panel 51 is wider than the base body 50. An upwardly cutout portion 51A is formed at the lower edge of the back panel 51. A recess 51E is formed in the center of the cutout portion 51A in the left-to-right direction, cutting out further upward than the cutout portion 51A. Above the cutout portion 51A in the back panel 51, a plurality of through-holes 51C are formed to penetrate the back panel 51 in the thickness direction, with the recess 51E sandwiched between them in the left-to-right direction. These through-holes 51C correspond to the through-holes 50B of the connecting member 50A. The back plate 51 is attached after the flush toilet 10 and pulverization pressure pump 30 have been attached to the base body 50 and the water supply hose 10F and drain hose 30C have been connected. Specifically, after confirming that the base body 50 can be moved with the flush toilet 10 and pulverization pressure pump 30 attached to the base body 50 and the water supply hose 10F and drain hose 30C connected, the back plate 51 is attached and the flush toilet 10 and pulverization pressure pump 30 are fixed to the base body 50.

[0015] Pressing members 51D are attached to both left and right edge portions of the back plate 51. The pressing members 51D are attached to the upper and lower ends of both left and right edge portions of the back plate 51. Each pressing member 51D has a nut portion 51F, a bolt portion 51G, and a butt portion 51H. The nut portion 51F is embedded in both left and right edge portions of the back plate 51. The nut portion 51F is, for example, a known insert nut. The bolt portion 51G is screwed into the nut portion 51F. The butt portion 51H is, for example, disk-shaped and coaxially connected to the protruding end of the bolt portion 51G protruding outward in the left and right direction from the nut portion 51F. When the bolt portion 51G is rotated in a direction to loosen it relative to the nut portion 51F, the butt portion 51H is displaced together with the bolt portion 51G relative to the back plate 51 in a direction away from the back plate 51 in the left and right direction. This allows each pressing member 51D to be displaced left and right relative to the back plate 51, thereby changing the dimension of its outward protrusion in the left and right direction from the back plate 51. In other words, the dimension of the back plate 51 in the left and right direction can be freely adjusted by displacing the pressing members 51D in the left and right direction.

[0016] [Support structure] Each of the pair of support portions 52 is formed, for example, by bending a strip-shaped metal plate into an L-shape. Each support portion 52 has an installation portion 52A forming one side of the L-shape and an attachment portion 52B forming the other side of the L-shape. Each support portion 52 is fixed to the back plate 51 with a wood screw while the installation portion 52A is in a forward extending position, with the lower surface of the installation portion 52A flush with the lower end surface of the back plate 51 and the attachment portion 52B in surface contact with the front surface of the back plate 51. To make the back plate 51 less likely to tip over, the installation portion 52A of the support portion 52 may be screwed to the floor surface F. The installation portion 52A of the support portion 52 also makes it easy to remove the screws. For this reason, a screw hole 52C is formed in advance in the installation portion 52A of the support portion 52, penetrating the installation portion 52A in the plate thickness direction.

[0017] [Wheel configuration] Each of the pair of wheels 53 has a rubber roller portion 53A and a pivotal support portion 53B that pivotally supports the roller portion 53A. Each wheel 53 is attached to both left and right ends of the base body 50, with the pivotal support portion 53B in contact with the rear end surface of the base body 50. In other words, each wheel 53 is provided at the rear end of the base body 50. Specifically, each wheel 53 is arranged with the central axis of the roller portion 53A facing in the left-right direction. When the base body 50 is placed on a floor surface F, the roller portion 53A is positioned above the underside of the base body 50 and is spaced apart from the floor surface F (see FIG. 2). When the base body 50 is installed in a closet C, the roller portion 53A is in contact with the rear side wall W of the closet C (see FIG. 2).

[0018] [Handle Configuration] Each of the pair of handles 54 has a handle body 54A and a male threaded portion 54B coaxially connected to the handle body 54A. Each handle 54 is detachably attached to both left and right ends of the front end of the base body 50. Specifically, a pair of screw holes 50F are formed in both left and right ends of the front end of the base body 50. The screw holes 50F are formed, for example, by known insert nuts. Each handle 54 can be attached to the base body 50 by screwing the male threaded portion 54B into each screw hole 50F, and can be removed from the base body 50 by loosening the male threaded portion 54B from each screw hole 50F.

[0019] [Configuration of a flush toilet and a pulverizing pressure pump] As shown in Figure 2, the flush toilet 10 has a toilet body 10A and a functional part 10B. The toilet body 10A has a bowl 10C and a drainage channel 10D that extends rearward from the downstream side of the bowl 10C. A drain outlet 10E located at the downstream end of the drainage channel 10D opens rearward.

[0020] The functional unit 10B is placed on the toilet body 10A. A toilet lid 10G and a toilet seat 10H are connected to the functional unit 10B so that they can be freely moved between an upright position that opens the bowl 10C and a reclined position that closes the bowl 10C. The functional unit 10B is provided with various functional components (not shown), such as a toilet flushing unit, an electric lid opening / closing unit, an electric toilet seat opening / closing unit, and a private parts washing unit. A water supply hose 10F for supplying water is connected to the functional unit 10B. The water supply hose 10F, for example, passes through the rear side wall W of the closet C and is connected to an existing water supply source (not shown). For example, the excess length of the water supply hose 10F is bundled into a ring and placed above the pulverizing pressure pump 30 (described later) (see FIG. 3).

[0021] The pulverizing pump 30 has an inlet 30A. The inlet 30A is connected to the drain outlet 10E of the flush toilet 10 via a connecting pipe 30B. Wastewater and wastewater discharged from the flush toilet 10 flow into the pulverizing pump 30 via the inlet 30A. The pulverizing pump 30 has the function of pulverizing the wastewater that flows in using a built-in rotating pulverizing blade (not shown) and pumping it together with the wastewater into a sewer pipe or the like (external). A drain hose 30C is connected to the pulverizing pump 30 to transport the wastewater and crushed wastewater to the sewer pipe. The drain hose 30C is routed, for example, through the ceiling of the closet C and above the ceiling, and connected to an existing sewage manhole or the like (not shown). For example, the excess length of the drain hose 30C is bundled into a ring and placed above the pulverizing pump 30 (see FIG. 3).

[0022] [An example of how to attach a flush toilet, pulverizer pump, and back panel to the base body] First, the worker places the base body 50 on the floor F of the renovated closet C. At this time, the worker places the base body 50 in the left-right center of the closet C (see FIG. 3) and brings the pair of roller parts 53A into contact with the rear side wall W of the closet C. Next, the worker places the flush toilet 10 on the front side of the base body 50 and secures the flush toilet 10 to the base body 50 using wood screws (not shown). Next, the worker places the pulverizer pressure pump 30 on the rear side of the base body 50 and connects the inlet 30A of the pulverizer pressure pump 30 to the drain outlet 10E of the flush toilet 10 via the connecting pipe 30B. Then, the worker secures the pulverizer pressure pump 30 to the base body 50 using wood screws (not shown).

[0023] Next, the worker attaches the back panel 51 to the base body 50. The left-right dimension of the back panel 51 is smaller than the short-side dimension (left-right direction) of the closet C (see FIG. 3). For example, the short-side dimension of the closet C is approximately 780 mm to 950 mm. In contrast, the left-right dimension of the back panel 51 is approximately 750 mm. Therefore, when attaching the back panel 51 to the base body 50, the chances of the back panel 51 rubbing against the left-right side walls W of the closet C can be reduced.

[0024] First, the worker positions the back panel 51 so that it stands upright relative to the base body 50. At this time, the worker orients the installation sections 52A of the pair of support sections 52 so that they extend forward relative to the back panel 51 (see FIG. 2). Then, the worker positions the back panel 51 behind the flush toilet 10 and in front of the pulverization pressure pump 30 (i.e., between the flush toilet 10 and the pulverization pressure pump 30), and inserts it vertically downward from above between the flush toilet 10 and the pulverization pressure pump 30. Then, the worker inserts the back panel 51 between the opposing upright sections 50D of the pair of connecting members 50A, and fits the base body 50 into the cutout section 51A of the back panel 51. At this time, the connecting pipe 30B and the water supply hose 10F fit into the recess 51E. Then, the worker brings the lower end surface of the back plate 51 and the lower end surfaces of the installation portions 52A of each support portion 52 into contact with the floor surface F. At this time, each support portion 52 comes into contact with the floor surface F both to the left of the front side of the base body 50 and to the right of the front side of the base body 50. The excess length portions of the water supply hose 10F and the drain hose 30C that come into contact with the floor surface are each bundled into a ring and positioned behind the back plate 51 and above the pulverization pressure feed pump 30.

[0025] The inner diameter of the through hole 50B of the connecting member 50A is larger than the inner diameter of the insertion hole 51C of the back plate 51. Therefore, even if, for example, the floor surface F is uneven and the back plate 51 is positioned slightly raised relative to the base body 50, the insertion hole 51C can be prevented from moving out of the opening range of the through hole 50B when the back plate 51 is viewed from the plate thickness direction. Then, the worker inserts a bolt into the through hole 50B and the insertion hole 51C and tightens a nut onto the bolt. This attaches the back plate 51 to the base body 50.

[0026] Next, the worker rotates the bolt portion 51G of each pressing member 51D in a direction to loosen it relative to the nut portion 51F. This causes each abutment portion 51H to come into contact with a side wall W located on the left and right of the closet C (see FIG. 3). In this way, each pressing member 51D is in a state of being stretched against the side wall W located on the left and right of the closet C. This determines the left and right position of the back panel 51 and prevents the back panel 51 from tipping over. To further prevent tipping, the back panel 51 can be fixed to the floor F with screws via the screw holes 52C of the installation portion 52A of the support portion 52. In this way, the worker installs the mobile toilet 1 in the renovated closet C.

[0027] The back panel 51 is made of wood. For this reason, for example, a remote control R for operating the flush toilet 10, a paper holder H, etc. can be easily attached to the back panel 51 in desired positions using wood screws. When considering ease of use, it is also possible to attach a handrail (not shown) with a paper holder H attached to the back panel 51, or to install a remote control stand with a remote control R attached inside the closet C.

[0028] [An example of the procedure for moving a toilet platform with a flush toilet and pulverizing pump mounted on it from the closet to the side of bed B] First, the worker screws the bolt portions 51G of each pressing member 51D into the deepest parts of the nut portions 51F until they bottom out, and moves each abutment portion 51H closer to both left and right side surfaces of the back plate 51. This moves each abutment portion 51H away from the side wall W. Next, the worker removes the nuts from the bolts inserted into the through holes 50B and the insertion holes 51C, and pulls the bolts out of the through holes 50B and the insertion holes 51C (see FIG. 2). Then, the worker lifts the back plate 51 vertically upward from the base main body 50 to remove it. In other words, the back plate 51 is vertically detachable from the base main body 50.

[0029] Next, the worker screws the male threaded portion 54B of the handle 54 into the screw hole 50F of the base body 50. Then, the worker grasps the handle 54 and lifts it (see FIG. 4). This causes the roller portions 53A of the wheels 53 to come into contact with the floor F, and the front side of the base body 50 lifts up, with the roller portions 53A in contact with the floor F serving as a fulcrum (see FIG. 4). Then, the worker pulls the handle 54 forward while lifting it, causing the roller portions 53A to roll on the floor F, and the base body 50 moves forward with the flush toilet 10 and pulverization pressure feed pump 30 mounted on it.

[0030] Then, while lifting the handle 54, the worker moves the base body 50, the flush toilet 10, and the pulverization pressure pump 30 to the desired position next to the bed B (see Figure 5). At this time, the excess lengths of the water supply hose 10F and the drain hose 30C that are bundled in a ring are extended to follow the flush toilet 10 and the pulverization pressure pump 30 (see Figure 5). The worker then reattaches the back panel 51 to the base body 50. The worker then removes the handle 54 from the base body 50. In this way, the worker completes the work of moving the flush toilet 10 that was installed and used in the closet C facing the room Br in which the bed B is installed, to the side of the bed B. This allows the user to transfer to and use the flush toilet 10 that has been moved to the side of the bed B without walking.

[0031] According to the first embodiment configured as above, the following effects are achieved.

[0032] The mobile toilet 1 comprises a base body 50 on which the flush toilet 10 can be placed and moved, and a back panel 51 that is detachable perpendicular to the base body 50, is wider than the base body 50, and comes into contact with the floor surface F. With this configuration, the back panel 51 can prevent the flush toilet 10 from tipping over in the left-right direction.

[0033] The mobile toilet 1 further includes support parts 52 that are provided on the back panel 51 and contact the floor surface F to the left of the front side of the base body 50 and to the right of the front side of the base body 50. With this configuration, the support parts 52 can prevent the back panel 51 from tipping forward.

[0034] The back panel 51 is placed between the flush toilet 10 and the pulverizing and pressure-feeding pump 30, which pulverizes waste that flows in from the flush toilet 10 and pressure-feeds it to the outside. This configuration makes it difficult for a user seated on the flush toilet 10 to see the pulverizing and pressure-feeding pump 30, the drain hose 30C extending from the pulverizing and pressure-feeding pump 30, and the like.

[0035] The dimension of the back panel 51 can be adjusted freely in the left-right direction (width direction) using the pressing member 51D. With this configuration, when the flush toilet 10 is installed in a closet C facing the living room Br, the bolt portion 51G of the pressing member 51D can be rotated in a direction that loosens it relative to the nut portion 51F, thereby pressing the abutment portion 51H against the side wall W of the closet C, thereby preventing the back panel 51 from falling over.

[0036] The base body 50 and back panel 51 are made of wood. The flush toilet 10 and pulverizing pressure pump 30 can be attached to the toilet moving base 3 in the same manner as when installing them in a toilet room, and no special work is required for the worker during installation.

[0037] The mobile toilet 1 is equipped with wheels 53 provided at the rear end of the base body 50. With this configuration, the flush toilet 10 and pulverization pressure pump 30 can be easily transported by lifting the front end of the base body 50.

[0038] The flush toilet is used by moving the flush toilet 10 that has been installed in the closet C facing the living room Br in which the bed B is installed to the side of the bed B. With this configuration, when the user is able to walk on their own, they can use the flush toilet 10 installed in the closet C facing the living room Br. Then, when the user has difficulty walking on their own, they can move the flush toilet 10 from the closet C facing the living room Br to the side of the bed B and use it. In other words, even if the user's physical ability changes, they can continue to use the flush toilet 10 that they are used to using. The flush toilet 10 is also easy to use because it does not require the effort of disposing of accumulated waste like a potty.

[0039] To use the flush toilet, the flush toilet 10 is placed on the movable base body 50, and a back panel 51, which is wider than the base body 50 and comes into contact with the floor surface F, is attached to the base body 50. With this configuration, the flush toilet 10 can be used while the back panel 51 prevents the flush toilet 10 from tipping over in the left-right direction.

[0040] <Other embodiments> The present disclosure is not limited to the embodiments described above and illustrated in the drawings, and the following embodiments, for example, are also included within the technical scope of the present disclosure.

[0041] Unlike the first embodiment, armrests 70 and a backrest 71 may be attached to the backboard 51 as shown in FIG.

[0042] Unlike the first embodiment, the number of handles may be one. In this case, the handle is preferably attached to the center of the front end of the base body in the left-right direction. Also, a recess for a finger to be placed may be formed in the front end of the base body.

[0043] Unlike the first embodiment, the back panel may be divided into multiple sections in the vertical direction. Specifically, the upper back panel may have multiple downwardly protruding dowels at the lower end, and the dowels of the upper back panel may be fitted into dowel holes formed at the upper end of the lower back panel. This allows the vertical dimension of the back panel to be freely adjusted by changing the number of back panels connected in the vertical direction.

[0044] Unlike the first embodiment, the support part may be made of synthetic resin. A piece of wood in the shape of a right triangle may be used as the support part. If the back panel is stabilized by contacting the lower end surface with the floor, the support part may not be provided. The support part may be attached to only one of the left and right sides of the back panel.

[0045] The front end of the base body may be formed larger than the outline of the bottom end surface of the toilet body. Specifically, as shown in Fig. 7, the base body 150 may be rectangular and wider than the bottom end surface of the toilet body 10A. As shown in Fig. 8, the front end of the base body 250 may protrude laterally beyond the toilet body 10A to provide a portion on which the user's feet can rest, and the rear end of the base body 250 may be provided with a portion protruding laterally to make it easier to place the pulverization pressure discharge pump 30.

[0046] Unlike the first embodiment, the base body and the back plate may be made of metal or plastic.

[0047] Unlike the first embodiment, a single cylindrical wheel extending in the left-right direction may be provided at the rear end of the base body. In other words, the number of wheels may be one or more.

[0048] Unlike the first embodiment, the back plate may be configured to protrude in at least one of the left and right directions relative to the base body.

[0049] Unlike the first embodiment, the back panel may be divided into two parts in the left-right direction. In this case, tension screws are provided between the two parts of the back panel, extending in the left-right direction, and the left and right back panels are pressed against the left and right side walls of the closet by extending the tension screws. The gap between the two parts of the back panel is hidden by a cover plate.

[0050] Unlike the first embodiment, the water supply hose and the drain hose may be extended when the portable toilet is moved from the closet to the side of the bed.

[0051] Unlike the first embodiment, as shown in Figure 9, the water supply hose 10F and the drain hose 30C are installed by penetrating the ceiling in closet C, located forward of the portable toilet 1. This makes it possible to reduce the change in the relative distance between the part of the water supply hose 10F and the drain hose 30C that penetrates the ceiling and the portable toilet 1, even when the portable toilet 1 is moved from closet C to the side of bed B. This makes it possible to shorten the length by which the water supply hose 10F and the drain hose 30C are bundled into a ring, which is expected to have the effect of keeping the area behind the back panel 51 neat and tidy when the portable toilet 1 is placed in closet C.
