[0009] [1] The bathtub disclosed herein comprises a sheet-made bathtub body that is used to fill with hot and cold water while suspended, and a rope that is arranged along the upper edge of the bathtub body when suspended, the bathtub body having a folded portion formed by folding back the outer edge of the sheet material that constitutes the bathtub body, the rope having a loop portion formed by folding back the end of the rope, the loop end of the rope that closes the loop portion being housed inside the folded portion, the loop end and the folded portion being sewn together with thread that passes from a first surface portion of the folded portion located on one side of the loop end to the loop end and a second surface portion of the folded portion located on the other side of the loop end. This configuration allows the loop end and the folded portion to be firmly fixed, thereby increasing the strength of the portion suspended from the suspension member. [2] In the bathtub described in [1] above, the pair of rope materials constituting the loop end of the rope may be sewn together with thread. With this configuration, the pair of rope materials constituting the loop end can be firmly connected to each other, thereby increasing the strength of the loop portion. [3] In the bathtub described in any of [1] to [2] above, the first and second surfaces may be sewn together along the edge of the rope material that forms the loop end. This configuration reduces the gap between the loop end and the edge of the folded-back portion, making it difficult for water to enter between the loop end and the edge of the folded-back portion. [4] The bathtub according to any one of [1] to [3] above may further include a reinforcing sheet material overlaid on the outside of the folded portion, the reinforcing sheet material having a first reinforcing portion overlaid on the first surface portion and a second reinforcing portion overlaid on the second surface portion, the folded portion and the reinforcing sheet material being sewn together with a thread that passes through the first reinforcing portion, the first surface portion, the loop end, the second surface portion, and the second reinforcing portion. This configuration allows the reinforcing sheet material, the folded portion, and the loop end to be firmly fixed, thereby increasing the strength of the portion suspended from the suspension member. [5] In the bathtub described in [4] above, the first reinforcing part and the second reinforcing part may be sewn together along the edge of the rope material that constitutes the loop end. This configuration reduces the gap between the loop end and the edge of the reinforcing sheet material, making it difficult for water to enter between the loop end and the edge of the reinforcing sheet material. [6] The bathroom of the present disclosure is equipped with a hanging member for hanging the bathtub described in any one of [1] to [5] above. With this configuration, the loop end and the folded portion can be firmly fixed, thereby increasing the strength of the part hung from the hanging member.

[0010] <Embodiment> 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] As shown in Figure 2, the bathtub 10 comprises a bathtub main body 20, two ropes 30, and four engaging parts 26. The bathtub main body 20 is made of sheet material. The bathtub main body 20 takes on a boat-like shape when hung from a hanging member 70 and filled with hot water (see Figure 1). The engaging parts 26 are provided at the four corners of the upper edge of the bathtub main body 20. The engaging parts 26 are the parts of the bathtub 10 that are hung from the hanging member. The state in which the engaging parts 26 are hung from the hanging member 70 and the bathtub main body 20 is filled with hot water is referred to as the in-use state.

[0016] 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 (see Figure 1). 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 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.

[0018] 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.

[0019] As shown in Figure 2, the upper edge of the bathtub body 20 has a pair of short sides 16 and a pair of long sides 17. When viewed from above in use, the upper edge of the bathtub 10 is rectangular. The length of the short sides 16 is equivalent to the shoulder width of an adult male. The length of the short sides 16 may be approximately 500 mm. The length of the long sides 17 is such that an adult male can sit comfortably inside the bathtub body 20. The length of the long sides 17 may be approximately 1600 mm.

[0020] As shown in Figure 2, the bathtub body 20 has a folded portion 14 formed by folding the outer edge of the sheet material 13 outward to form a cylindrical shape. The step created by forming the folded portion 14 is formed on the outside of the bathtub body 20. The folded portion 14 is provided on a pair of short sides 16 and a pair of long sides 17. The folded portion of the sheet material 13 is folded and sewn in three (see Figure 7). The stitching portion 14A, which sews the part of the folded portion 14 excluding the wide portion 27 described below, is provided at the edge of the rope 30 arranged inside the folded portion 14 (see Figure 4). The folded portion 14 has a double structure formed by folding the sheet material 13, and therefore functions to reinforce the upper edge of the bathtub body 20 together with the rope 30.

[0021] As shown in Figure 2, the ropes 30 are arranged one on each of the long sides 17 of the upper edge of the bathtub body 20 when in use. When in use, the long sides 17 of the upper edge of the bathtub body 20 are designed to be less likely to bend downward. This allows the bathtub body 20 to maintain its boat-shaped shape, allowing the bathtub body 20 to hold a sufficient amount of hot and cold water.

[0022] The rope 30 has a tensile strength that will not break even if a person sits on the upper edge of the bathtub body 20 when in use. A polyester rope may be used for the rope 30. The rope 30 is passed through the entire length of the folded portion 14 provided on the long side 17. When in use, the rope 30 is stretched between the walls W1 and W2 (see Figure 1).

[0023] As shown in Figures 3 to 5, the engaging portion 26 has a wide portion 27, a loop portion 31, a reinforcing sheet material 43, and a sewn portion 40. The wide portion 27 is provided at both longitudinal ends of the folded-back portion 14 provided on the long side 17. The wide portion 27 is formed by making the folding margin of the sheet material 13 larger than other portions of the folded-back portion 14 on the long side 17. The width dimension of the wide portion 27 is approximately constant along the extension direction of the long side 17. The wide portion 27 makes the engaging portion 26 less likely to stretch.

[0024] The loop portions 31 are provided at both ends of the rope 30 in the extension direction. The loop portions 31 are formed by folding back the ends of the rope 30. The loop portions 31 are hooked onto hanging members 70 provided on the walls W1 and W2. The loop end portions 33 of the rope 30 that close the loop portions 31 are housed inside the wide portion 27, as shown in FIG. 3 .

[0025] As shown in Figure 3, the loop end 33 has a loop sewn portion 35. The loop sewn portion 35 is formed by sewing together a pair of rope materials 34 that make up the loop end 33 with thread. The loop sewn portion 35 is sewn in a zigzag pattern. The thread of the loop sewn portion 35 passes through the pair of rope materials 34 alternately.

[0026] As shown in Fig. 3, the wide portion 27 has a first surface portion 36 and a second surface portion 37. The second surface portion 37 is a portion of the sheet material 13 that overlaps with the first surface portion 36. The first surface portion 36 is disposed on the outer side (one side) of the loop end portion 33. The second surface portion 37 is disposed on the inner side (the other side) of the loop end portion 33.

[0027] As shown in Fig. 5, the reinforcing sheet material 43 is folded in half and placed on the surface of the wide portion 27. The reinforcing sheet material 43 has a first reinforcing portion 44 and a second reinforcing portion 45. The first reinforcing portion 44 is placed on the surface of the first surface portion 36. The second reinforcing portion 45 is placed on the surface of the second surface portion 37.

[0028] The reinforcing sheet material 43 may have a two-layer structure in which a polyester fabric and a polyurethane film are laminated together, similar to the sheet material 13 that constitutes the bathtub body 20. In this case, the polyester fabric may be placed on the outside of the reinforcing sheet material 43, and the polyurethane film may be placed on the inside of the reinforcing sheet material 43. The outside of the reinforcing sheet material 43 is the side opposite to the side that contacts the wide portion 27, and the inside of the reinforcing sheet material 43 is the side that contacts the wide portion 27.

[0029] As shown in Figures 5 to 7, the sewn portion 40 has a primary sewn portion 41 and a secondary sewn portion 42. As shown in Figure 5, the primary sewn portion 41 is formed by sewing the loop end portion 33 and the folded portion 14 together before sewing the reinforcing sheet material 43. As shown in Figure 6, the secondary sewn portion 42 is formed by sewing the reinforcing sheet material 43 and the folded portion 14 together after the reinforcing sheet material 43 is placed on the front side of the folded portion 14. The primary sewn portion 41 and the secondary sewn portion 42 are sewn in the same position in the engaging portion 26. The primary sewn portion 41 and the secondary sewn portion 42 overlap. The primary sewn portion 41 and the secondary sewn portion 42 each have a hem sewn portion 46 and a center sewn portion 47.

[0030] The edge sewn portion 46 has a long side sewn portion 46A and a pair of short side sewn portions 46B in both the primary sewn portion 41 and the secondary sewn portion 42. The long side sewn portion 46A extends along the edge of the rope material 34 in both the primary sewn portion 41 and the secondary sewn portion 42. The short side sewn portion 46B extends across the pair of rope materials 34 in both the primary sewn portion 41 and the secondary sewn portion 42. The middle sewn portion 47 sews the center of the width of each rope material 34 in both the primary sewn portion 41 and the secondary sewn portion 42. The middle sewn portion 47 extends in a straight line from one short side sewn portion 46B to the other short side sewn portion 46B in both the primary sewn portion 41 and the secondary sewn portion 42.

[0031] The primary sewn portion 41 will now be described (see Figures 5 and 7). As shown in Figure 5, the edge sewn portion 46 sews the edge of the folded portion 14. The long side sewn portion 46A extends along one long side of the first surface portion 36. The thread of the long side sewn portion 46A passes through the overlapping first surface portion 36 and second surface portion 37 at the edge of the rope material 34. The edge of the first surface portion 36 is folded and sewn. The long side sewn portion 46A closes the gap between the folded portion 14 and the loop end portion 33.

[0032] The short side sewn portions 46B extend along a pair of short sides of the first surface portion 36. The thread of the short side sewn portions 46B passes through the overlapping first surface portion 36 and second surface portion 37. The portion of the thread of the short side sewn portions 46B that crosses the rope material 34 passes through the first surface portion 36, the rope material 34, and the second surface portion 37.

[0033] The middle sewn portion 47 sews the center of the folded-back portion 14. The thread of the middle sewn portion 47 passes through the first surface portion 36, the rope material 34, and the second surface portion 37 in this order.

[0034] The secondary sewn portion 42 will now be described (see FIGS. 6 and 7). As shown in FIG. 6, the edge sewn portion 46 sews the edge of the reinforcing sheet material 43. The long side sewn portion 46A extends along one long side of the first reinforcing portion 44 and the second reinforcing portion 45. The thread of the long side sewn portion 46A passes through the first reinforcing portion 44, the first surface portion 36, the second surface portion 37, and the second reinforcing portion 45, which are overlapped at the edge of the rope material 34. The edges of the first reinforcing portion 44 and the second reinforcing portion 45 are each folded back and sewn. The long side sewn portion 46A overlaps with the long side sewn portion 46A of the primary sewn portion 41 on the first surface portion 36 and the second surface portion 37.

[0035] The short-side sewn portions 46B extend along a pair of short sides of the first reinforcing portion 44 and the second reinforcing portion 45. The thread of the short-side sewn portions 46B passes through the overlapping first reinforcing portion 44, first surface portion 36, second surface portion 37, and second reinforcing portion 45. The portion of the thread of the short-side sewn portions 46B that crosses the rope material 34 passes through the first reinforcing portion 44, first surface portion 36, rope material 34, second surface portion 37, and second reinforcing portion 45. The short-side sewn portions 46B overlap with the short-side sewn portions 46B of the primary sewn portion 41 on the first surface portion 36 and the second surface portion 37.

[0036] The middle sewn portion 47 sews the center of the reinforcing sheet material 43. The thread of the middle sewn portion 47 passes through the first reinforcing portion 44, the first surface portion 36, the rope material 34, the second surface portion 37, and the second reinforcing portion 45, in that order. The middle sewn portion 47 overlaps with the middle sewn portion 47 of the primary sewn portion 41 in the first surface portion 36, the rope material 34, and the second surface portion 37.

[0037] 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.

[0038] 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 hot water at the appropriate temperature into the bathtub body 20. Once the bather has poured the appropriate amount of water into the bathtub body 20, he or she stops the discharge of the faucet device 60. The bottom surface 11 of the bathtub 10 comes into contact with the floor F when the bathtub 10 is filled with hot water.

[0039] Next, the bather enters the bathtub 10. Because the bottom surface 11 of the bathtub 10 is in contact with the floor F, the weight of the water stored in the bathtub body 20 and most of the weight of the bather are supported by the floor F. The bather enters the bathtub 10 with their head facing the wall W2 and their legs facing the wall W1. The bather's back is supported by the side surface 12. Because the rope 30 does not enter the short side 16 of the bathtub body 20, the bather only feels the softness of the fabric when they place their head or legs on the short side 16 of the bathtub body 20, allowing them to relax while bathing.

[0040] 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.

[0041] The embodiment configured as described above provides the following advantages. The bathtub 10 includes a sheet-made bathtub body 20 and a rope 30. The bathtub body 20 is used by filling it with hot and cold water while suspended. The rope 30 is arranged along the upper edge of the bathtub body 20 when suspended. The bathtub body 20 has a folded portion 14. The folded portion 14 is formed by folding back the outer edge of the sheet material 13 that constitutes the bathtub body 20. The rope 30 has a loop portion 31 formed by folding back the end of the rope 30. The loop end 33 of the rope 30, which closes the loop portion 31, is housed inside the folded portion 14. The loop end 33 and the folded portion 14 are sewn together with thread. The thread passes from the first surface portion 36, which is located outside the loop end 33 of the folded portion 14, to the loop end 33 and the second surface portion 37, which is located inside the loop end 33 of the folded portion 14. With this configuration, the loop end 33 and the folded portion 14 can be firmly fixed, thereby increasing the strength of the engaging portion 26 that is suspended from the suspension member. Even if part of the thread sewing the loop end 33 and the folded portion 14 together becomes frayed, the loop end 33 and the folded portion 14 can be prevented from shifting.

[0042] The pair of rope materials 34 constituting the loop end portion 33 of the rope 30 are sewn together with thread. With this configuration, the pair of rope materials 34 constituting the loop end portion 33 can be firmly fixed together, thereby increasing the strength of the loop portion 31.

[0043] The first surface portion 36 and the second surface portion 37 are sewn together along the edge of the rope material 34 that constitutes the loop end portion 33. With this configuration, the gap between the loop end portion 33 and the edge of the turned-up portion 14 can be made small, making it difficult for water to enter between the rope material 34 and the edge of the turned-up portion 14.

[0044] The bathtub 10 has a reinforcing sheet material 43 that is overlaid on the outside of the folded portion 14. The reinforcing sheet material 43 has a first reinforcing portion 44 that is overlaid on the first surface portion 36, and a second reinforcing portion 45 that is overlaid on the second surface portion 37. The folded portion 14 and the reinforcing sheet material 43 are sewn together with thread. The thread passes from the first reinforcing portion 44 through the first surface portion 36, the loop end portion 33, the second surface portion 37, and the second reinforcing portion 45. With this configuration, the reinforcing sheet material 43, the folded portion 14, and the loop end portion 33 can be firmly fixed, thereby increasing the strength of the engagement portion 26 that is suspended from the suspension member.

[0045] The first reinforcing portion 44 and the second reinforcing portion 45 are sewn together along the edge of the rope material 34 that constitutes the loop end portion 33. With this configuration, the gap between the loop end portion 33 and the edge of the reinforcing sheet material 43 can be made small, making it difficult for water to enter between the loop end portion 33 and the edge of the reinforcing sheet material 43.
