[0009] [1] The bathtub disclosed herein includes a sheet-made bathtub body that is suspended and filled with hot water. When viewed from above with the bathtub body filled with hot water, the upper edge of the bathtub body is rectangular. The bathtub body also includes an insertion section along at least one short side of the upper edge of the bathtub body, and an insertion member that is inserted into the insertion section and suspended from a hanging member installed in the bathroom. This configuration prevents the ends of the long sides of the upper edge of the bathtub body from shifting toward the center in the longitudinal direction due to the insertion member. Therefore, the longitudinal dimensions of the sheet-made bathtub can be prevented from shrinking even when filled with hot water. [2] In the bathtub described in [1] above, the insert member may be a rope. With this configuration, the insert member itself can be easily hooked onto the hanging member. [3] In the bathtub described in [1] above, the insert member may be a rod-shaped member. With this configuration, the insert member is less likely to bend than a rope, which can further prevent the longitudinal dimension of the bathtub from becoming smaller. [4] In the bathtub described in any of [1] to [3] above, the insert member may be provided around the entire upper edge of the bathtub body. With this configuration, the insert member can reinforce the entire upper edge of the bathtub body. [5] The bathtub described in any of [1] to [4] above may be provided with a cushion member attached to the short side of the upper edge of the bathtub body. With this configuration, the short side of the upper edge of the bathtub body is soft enough for the bather to rest their head on, allowing them to relax while bathing. [6] The bathroom of the present disclosure has a hanging member for hanging the bathtub described in any of [1] to [5] above, which is attached to the wall. With this configuration, the short side of the upper edge of the bathtub can be positioned close to the wall.

[0010] <Embodiment 1> The bathtub 10 in this embodiment is placed in a bathroom 50, as shown in Figure 1. The bathroom 50 includes a wall W, a ceiling C, a floor F, a faucet device 60, and four hanging members 70. The faucet device 60 and hanging members 70 are fixed to the wall W. The wall W includes walls W1, W2, and W3 connected to each other, and a wall (not shown) facing wall W3. The wall (not shown) has an entrance / exit for passing between the adjacent changing room and the bathtub. A door is provided at the entrance / exit. The floor F has a gentle downward slope toward a drain (not shown).

[0011] Bathroom 50 does not have a freestanding bathtub. Bathtub 10 is placed along wall W3 of bathroom 50. When bathtub 10 is installed in bathroom 50, a washing area for bathers to wash their bodies is formed on the entrance / exit side of bathroom 50. Bathtub 10 is detachable from bathroom 50. By removing bathtub 10, bathroom 50 can be conveniently used as a shower room.

[0012] The faucet device 60 is a shower device. The faucet device 60 has a faucet 61, a water outlet pipe 62, an overhead shower 63, and a hand shower 65. The faucet 61 is connected to a water supply pipe and a hot water supply pipe (not shown). The faucet 61 is a mixer faucet. The faucet 61 can adjust the temperature of the hot and cold water being discharged, adjust the amount of hot and cold water being discharged, switch between water discharge and stop, switch the flow path, etc. The faucet 61 can select either the water outlet pipe 62, the overhead shower 63, or the hand shower 65 to discharge hot and cold water. The hot water or cold water discharged from the faucet device 60 is referred to as hot and cold water regardless of the temperature, the mixing ratio of hot and cold water, etc.

[0013] The water outlet pipe 62 extends from the faucet 61. The water outlet pipe 62 extends in a direction away from the wall W1. The overhead shower 63 is provided above the faucet 61. The overhead shower 63 is connected to the faucet 61 via piping 67. The piping 67 extends vertically upward from the faucet 61 along the wall W1 and is bent at its upper end in a direction away from the wall W1. The overhead shower 63 is provided at the tip of the piping 67. The hand shower 65 is connected to the faucet 61 via a hose 69. The hand shower 65 is movable within the length of the hose 69.

[0014] A hooking portion 26 of the bathtub 10, which will be described later, is hooked onto each hanging member 70. Each hanging member 70 has a J-shaped bend so that the hooking portion 26 can be hooked from above. The hanging members 70 are provided on two opposing walls W1, W2 of the wall W. Two hanging members 70 are provided on each opposing wall W1, W2, for a total of four. The two hanging members 70 provided on each wall W1, W2 are spaced apart horizontally. The two hanging members 70 provided on wall W1 are located below the faucet 61. The distance between the two hanging members 70 provided on wall W2 is the same as the distance between the two hanging members 70 provided on wall W1. The four hanging members 70 are arranged at the same height.

[0015] The bathtub 10 comprises a bathtub main body 20 and an insert member 30. The bathtub main body 20 is made of sheet. The bathtub main body 20 takes on a boat shape when hung from a hanging member 70 and filled with hot water. The state in which the bathtub main body 20 is hung from the hanging member 70 and filled with hot water is referred to as the in-use state.

[0016] When in use, the bathtub body 20 has a bottom surface 11 and side surfaces 12. When in use, the bottom surface 11 comes into contact with the floor F. This allows the floor F to support most of the load of the bathtub 10 when in use. When in use, the side surfaces 12 rise upward, surrounding the bottom surface 11. This allows the bathtub body 20 to hold an amount of hot water suitable for bathing.

[0017] The side surface portion 12 has a first side surface portion 21, a second side surface portion 22, a third side surface portion 23, and a fourth side surface portion 24. The first side surface portion 21, the second side surface portion 22, the third side surface portion 23, and the fourth side surface portion 24 are continuous and surround the bottom surface portion 11.

[0018] The bathtub body 20 is made of a single sheet material 13 cut to a predetermined shape. The sheet material 13 has little elasticity, and is able to maintain the shape of the bathtub body 20 in a boat-like shape when in use. The sheet material 13 is flexible, impermeable (waterproof), and durable against tension.

[0019] The sheet material 13 may be made by overlapping multiple materials. The multiple materials may be bonded with an adhesive. As a specific example, the sheet material 13 may have a two-layer structure in which a polyester fabric and a polyurethane film are laminated. The polyester fabric may be placed on the side of the sheet material 13 that forms the outer surface of the bathtub body 20, and the polyurethane film may be placed on the side of the sheet material 13 that forms the inner surface of the bathtub body 20. The inner side of the bathtub body 20 is the side where hot and cold water is stored, and the outer side of the bathtub body 20 is the side opposite the side where hot and cold water is stored.

[0020] As shown in Figure 2, the upper edge portion 15 of the bathtub body 20 has a rectangular shape when viewed from above in use. The upper edge portion 15 of the bathtub body 20 is the upper edge of the side surface portion 12. The upper edge portion 15 of the bathtub body 20 has a pair of short sides 16 and a pair of long sides 17. The first side surface portion 21 and the second side surface portion 22 extend downward from each of the pair of long sides 17. The third side surface portion 23 and the fourth side surface portion 24 extend downward from each of the pair of short sides 16.

[0021] The length of the short side 16 is set to be the same as the shoulder width of an adult male. The length of the short side 16 may be approximately 500 mm. The length of the long side 17 is set to be a dimension that allows an adult male to sit comfortably inside the bathtub body 20. The length of the long side 17 may be approximately 1600 mm.

[0022] An insertion section 25 is formed on each of the pair of short sides 16. As shown in Figure 3, the insertion section 25 is formed by folding the outer edge of the sheet material 13 back to the outside of the bathtub body 20. The folded portion of the sheet material 13 is folded in three and sewn. The insertion section 25 is tubular and extends along the short sides 16. A step created by forming the insertion section 25 is formed on the outside of the bathtub body 20. The insertion member 30 is inserted into the insertion section 25.

[0023] The insertion portion 25 is formed continuously over the entire length of the short side 16. The insertion portion 25 has a double structure formed by folding back the sheet material 13, and therefore functions to reinforce the short side 16 together with the insertion member 30. When in use, the short side 16 is less likely to bend downward.

[0024] The insert member 30 is a rope. As shown in Figure 2, one insert member 30 is provided on each of the pair of short sides 16 of the upper edge 15 of the bathtub body 20 when in use. The insert member 30 is arranged along the short sides 16. The length dimension of the insert member 30 is such that it can stretch the short sides 16 taut without slack. The insert member 30 has a tensile strength that will not break even if a person sits on the upper edge 15 of the bathtub body 20 when in use. The insert member 30 may be a polyester rope. The insert member 30 runs along the entire length of the insertion portion 25.

[0025] As shown in Figure 4, engagement portions 26 are provided at both ends of the insertion member 30 in the extension direction. The engagement portions 26 are formed by folding back the end of a rope in a loop shape. The engagement portions 26 are arranged on the outside of the insertion portion 25. The engagement portions 26 are provided at the four corners of the upper edge portion 15 of the bathtub main body 20 (see Figure 2). The engagement portions 26 are hooked onto hanging members 70 provided on the walls W1 and W2. The insertion member 30 is hung from the hanging member 70 by hooking the engagement portions 26 onto the hanging member 70.

[0026] An example of a method for bathing using bathtub 10 will be described below. First, the bather sets up bathtub 10 in bathroom 50. Specifically, the bather sets up bathtub 10 by hooking engaging portion 26 of bathtub main body 20 onto hanging member 70 of bathroom 50. The bather can easily set up bathtub 10 in bathroom 50 by simply hooking engaging portion 26 onto hanging member 70.

[0027] Next, the bather fills the bathtub body 20 with hot water. Specifically, the bather operates the faucet device 60 in the bathroom 50 to pour water at the appropriate temperature into the bathtub body 20. As a result, the weight of the water pulls the upper edge 15 of the bathtub body 20 downward. This downward force acts on the insert member 30 on the short side 16. Because both ends of the insert member 30 are fixed to the hanging member 70, the short side 16 is held close to the walls W1 and W2 while maintaining its height. The insert member 30 prevents the longitudinal ends of the long side 17 from shifting toward the center. This prevents the longitudinal dimension of the bathtub body 20 from shrinking even when water is poured into the bathtub body 20, allowing the bather to fill the bathtub body 20 with enough water. Once the bather has poured the appropriate amount of water into the bathtub body 20, they stop the faucet device 60 from discharging. The bottom surface 11 of the bathtub 10 contacts the floor F when filled with hot water.

[0028] Next, the bather enters bathtub 10. Because bottom surface 11 of bathtub 10 is in contact with floor F, the weight of the hot water stored in bathtub body 20 and the weight of the bather are mostly supported by floor F. The bather enters bathtub 10 with their head facing wall W2 and their legs facing wall W1. The bather's back is supported by third side surface 23.

[0029] When the bather has finished bathing, he or she removes the drain plug (not shown) from the bathtub main body 20 to drain the hot and cold water. The bather then removes the bathtub 10 from the walls W1, W2. The bather can easily remove the bathtub 10 from the walls W1, W2 by simply removing the attachment part 26 from the hanging member 70. The bather then washes the removed bathtub 10 and hangs it on a faucet device 60 or the like to dry it. The bather then folds the bathtub main body 20 to make it compact and stores it outside the bathroom.

[0030] The embodiment configured as described above offers the following advantages. The bathtub 10 includes a sheet-made bathtub body 20. The bathtub body 20 is used in a suspended state by filling it with hot water. The upper edge 15 of the bathtub body 20 is rectangular in plan view when filled with hot water. The upper edge 15 of the bathtub body 20 includes an insertion section 25 and an insertion member 30. The insertion section 25 is provided along the short side 16 of the upper edge 15 of the bathtub body 20. The insertion member 30 is inserted into the insertion section 25. The insertion member 30 is suspended from a hanging member 70 provided in the bathroom 50. With this configuration, the insertion member 30 prevents both ends of the long side 17 of the upper edge 15 of the bathtub body 20 from shifting toward the center in the longitudinal direction. Therefore, the longitudinal dimensions of the sheet-made bathtub 10 can be prevented from becoming smaller even when filled with hot water.

[0031] The insertion member 30 is a rope. With this configuration, the insertion member 30 itself can be easily hooked onto the hanging member 70.

[0032] The walls W1 and W2 of the bathroom 50 have hanging members 70 for suspending the bathtub 10. With this configuration, the short side 16 of the upper edge 15 of the bathtub body 20 can be positioned close to the walls W1 and W2.

[0033] <Embodiment 2> Next, a bathtub 10 according to a second embodiment of the present disclosure will be described with reference to Figures 5 and 6. The bathtub 10 of this embodiment differs from the first embodiment in that an insert member 30 is provided around the entire periphery of the upper edge 15 of the bathtub body 20. Note that components similar to those of the first embodiment are given the same reference numerals and redundant explanations will be omitted.

[0034] The bathtub 10 of this embodiment, like embodiment 1, comprises a bathtub body 20 and an insert member 30, and an insert portion 25 is provided on the upper edge 15 of the bathtub body 20. The insert portion 25 is formed continuously around the entire circumference of the upper edge 15 of the bathtub body 20. As with embodiment 1, the insert portion 25 has a double structure formed by folding back the sheet material 13, and therefore functions together with the insert member 30 to reinforce the entire circumference of the upper edge 15 of the bathtub body 20. As with embodiment 1, the insert member 30 is passed through the entire length of the insert portion 25. The engagement portion 26 is formed by folding back a portion of the insert member 30 in a loop shape. When in use, the entire circumference of the upper edge 15 of the bathtub body 20 is less likely to bend downward.

[0035] 6, the insertion member 30 is a rope having a cushion member 81. The cushion member 81 covers the entire outer circumferential surface of the rope. The cushion member 81 is provided integrally with the rope.

[0036] As described above, in this embodiment, as in embodiment 1, the insertion member 30 makes it difficult for both ends of the long side 17 of the upper edge portion 15 of the bathtub body 20 to move toward the center in the longitudinal direction, so that even when hot water is filled in the sheet-made bathtub 10, the longitudinal dimension of the bathtub 10 can be prevented from becoming smaller.

[0037] The insert member 30 is provided around the entire periphery of the upper edge 15 of the bathtub body 20. With this configuration, the insert member 30 can reinforce the entire periphery of the upper edge 15 of the bathtub body 20.

[0038] The bathtub 10 is equipped with cushion members 81 provided around the entire periphery of the upper edge 15 of the bathtub main body 20. With this configuration, the bather does not feel any hardness when resting their head or arms on the upper edge 15 of the bathtub main body 20, allowing them to relax while bathing.

[0039] <Embodiment 3> Next, a bathtub 10 and a bathroom 50 according to a third embodiment of the present disclosure will be described with reference to Figure 7. The bathtub 10 of this embodiment differs from the first embodiment in that the insert member 30 is a rod-shaped body. Note that the same components as those in the first embodiment will be assigned the same reference numerals and redundant explanations will be omitted.

[0040] The bathtub 10 according to this embodiment, like the first embodiment, includes a bathtub body 20 and an insert member 30, and an insert portion 25 is provided on the short side 16 of the upper edge portion 15.

[0041] As shown in Figure 7, the insertion member 30 is a rod-shaped body. The rod-shaped body extends linearly. A rod-shaped body has higher rigidity than a rope and is less likely to bend. Both ends of the insertion member 30 protrude outward from the end of the insertion portion 25. Both ends of the insertion member 30 form the engagement portion 26. A groove portion 82 is formed in the engagement portion 26. The hanging member 70 fits into the groove portion 82. This limits the axial movement of the insertion member 30.

[0042] As described above, in this embodiment, as in embodiment 1, the insertion member 30 makes it difficult for both ends of the long side 17 of the upper edge portion 15 of the bathtub body 20 to move toward the center in the longitudinal direction, so that even when hot water is filled in the sheet-made bathtub 10, the longitudinal dimension of the bathtub 10 can be prevented from becoming smaller.

[0043] The insertion member 30 is a rod-shaped body. With this configuration, the insertion member 30 is less likely to bend than if it were a rope, so it is possible to further prevent the longitudinal dimension of the bathtub 10 from becoming smaller.

[0044] Because the rod-shaped member is less likely to bend than a rope, the short sides of the upper edge 15 of the bathtub body 20 can be positioned closer to the walls W1 and W2, thereby maximizing the use of space in the bathroom 50. By supporting the bather's head on either wall W1 or W2, the bather can bathe in a relaxed state without hitting their head against the insert member 30 on the short side 16.

[0045] <Embodiment 4> Next, a bathtub 10 according to a fourth embodiment of the present disclosure will be described with reference to Figure 8. The bathtub 10 of this embodiment differs from the first embodiment in that a cushion member 83 is provided on the outside of the insertion portion 25. Note that the same components as those of the first embodiment are given the same reference numerals, and redundant explanations will be omitted.

[0046] The bathtub 10 according to this embodiment, like the first embodiment, includes a bathtub body 20 and an insert member 30, and an insert portion 25 is provided on the short side 16 of the upper edge portion 15.

[0047] The cushion member 83 is provided on one of the pair of short sides 16. As shown in FIG. 9, the cushion member 83 has an annular shape in a cross section perpendicular to the extension direction of the short side 16. The cushion member 83 covers the entire outer peripheral surface of the insertion portion 25. The center of the cushion member 83 is a storage space 84. The insertion portion 25 is stored in the storage space 84. The storage space 84 is formed over the entire length of the cushion member 83.

[0048] The cushion member 83 is detachable from the short side 16. The cushion member 83 has a slit 85. The slit 85 is continuous over the entire length of the cushion member 83. The slit 85 can be opened to a size that allows the insertion portion 25 to be inserted and removed from the storage space 84. The cushion member 83 can be attached to the outside of the insertion portion 25 by opening the slit 85 and fitting the insertion portion 25 into the storage space 84. When the cushion member 83 is attached to the short side 16, the elastic force of the cushion member 83 closes the slit 85. As a result, the sheet material 13 of the bathtub body 20 is elastically sandwiched between the cushion members 83 on both sides of the slit 85.

[0049] As described above, in this embodiment, as in embodiment 1, the insertion member 30 makes it difficult for both ends of the long side 17 of the upper edge portion 15 of the bathtub body 20 to move toward the center in the longitudinal direction, so that even when hot water is filled in the sheet-made bathtub 10, the longitudinal dimension of the bathtub 10 can be prevented from becoming smaller.

[0050] The bathtub 10 is equipped with a cushion member 83 provided on the short side 16 of the upper edge 15 of the bathtub body 20. With this configuration, the short side 16 of the upper edge 15 of the bathtub body 20 is soft enough for the bather to rest their head on, allowing them to relax while bathing.

[0051] <Embodiment 5> Next, a bathtub 10 and bathroom 50 according to a fifth embodiment of the present disclosure will be described with reference to Figure 10. The bathtub 10 of this embodiment differs from the first embodiment in that it is provided with an accessory part 86. Note that components similar to those of the first embodiment will be given the same reference numerals and redundant explanations will be omitted.

[0052] The bathtub 10 according to this embodiment, like the first embodiment, includes a bathtub body 20 and an insert member 30, and an insert portion 25 is provided on the short side 16 of the upper edge portion 15.

[0053] The attachment portion 86 is formed from a sheet material similar to the sheet material 13 of the bathtub body 20. The attachment portion 86 may be formed by extending the sheet material 13 of the bathtub body 20. The attachment portions 86 are provided at both longitudinal ends of the bathtub body 20. Each attachment portion 86 extends from the short side 16 of the upper edge portion 15 of the bathtub body 20 toward the respective walls W1 and W2. The attachment portion 86 has an attachment attachment portion 87. The attachment attachment portion 87 can be hooked onto the hanging member 70 or the insert member 30. The bather can use the attachment portion 86 as a pillow. The bather can rest their head on the attachment portion 86 and relax while bathing.

[0054] As described above, in this embodiment, as in embodiment 1, the insertion member 30 makes it difficult for both ends of the long side 17 of the upper edge portion 15 of the bathtub body 20 to move toward the center in the longitudinal direction, so that even when hot water is filled in the sheet-made bathtub 10, the longitudinal dimension of the bathtub 10 can be prevented from becoming smaller.
