Description

[Technical Field]

[0001] The present disclosure relates to bathtubs and bathrooms. [Background technology]

[0002] Conventionally, a sheet-made bathtub that is used in a suspended state has been known, as described in, for example, the following Patent Document 1. The bathtub is suspended by hooking the upper corners onto a hanging member installed in the bathroom. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-260180 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned sheet bathtub, if the part that is hooked onto the hanging member stretches, the amount of hot water that can be stored in the bathtub may decrease. If water is left on the above-mentioned sheet bathtub, mold may grow, making it difficult to keep clean. There has been a demand for a sheet bathtub that is easier to use by making the part that is hooked onto the hanging member less likely to stretch and easier to keep clean.

[0005] The present disclosure was completed based on the above circumstances, and aims to provide a bathtub and bathroom that can improve usability in a sheet-made bathtub. [Means for solving the problem]

[0006] The bathtub disclosed herein comprises a sheet-made bathtub body that is used by filling it with hot and cold water when suspended, and a rope that is arranged along the upper edge of the bathtub body when suspended.The upper edge of the bathtub body is provided with an insertion section into which the rope is inserted, and a through hole is formed in the insertion section.The space between the inside of the insertion section and the through hole is closed at the periphery of the through hole, and the rope passes through the inside of the insertion section above the through hole when suspended.

[0007] The bathroom of the present disclosure is equipped with a hanging member for suspending the bathtub. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] [1] A bathtub includes a sheet-made bathtub body that is used to fill with hot and cold water when suspended, and a rope that runs along the upper edge of the bathtub body when suspended. The upper edge of the bathtub body is provided with an insertion section through which the rope is inserted. The insertion section has a through-hole formed in it, and the periphery of the through-hole closes the gap between the interior of the insertion section and the through-hole. The rope passes through the interior of the insertion section above the through-hole when suspended. With this configuration, when the bathtub body is suspended by hooking the through-hole onto a hanging member or the like installed in the bathroom, the load on the bathtub body is borne by the rope passing above the through-hole, making the portion hooked onto the hanging member less likely to stretch than when the load is borne solely by the bathtub body. The closed gap between the interior of the insertion section and the through-hole at the periphery of the through-hole prevents water from entering the insertion section through the through-hole, making it easier to keep the bathtub clean. Therefore, it is possible to improve the usability of a sheet-made bathtub. [2] In the bathtub described in [1] above, the rope may have a loop that goes around the through hole. With this configuration, the loop is held in place at the through hole, preventing the rope from shifting in the direction of extension. [3] In the bathtub described in any of [1] to [2] above, the periphery of the through hole may be closed by sewing. For example, if the periphery of the through hole is closed by metal fittings, there is a risk of damage to the joint between the metal fittings and the insertion part. Since the periphery of the through hole is closed by sewing, durability can be improved compared to when metal fittings or the like are used. [4] In the bathtub described in any of [1] to [3] above, when the bathtub body is filled with hot water, the upper edge of the bathtub body may be rectangular in plan view, the insertion part may be provided along the long side of the upper edge of the bathtub body, and the rope may extend along the long side of the upper edge of the bathtub body. With this configuration, the long side of the upper edge of the bathtub body is less likely to droop when filled with hot water, thereby maintaining the amount of hot water that can be stored in the bathtub body. [5] The bathtub described in any of [1] to [4] above may be provided with a hooking member that is passed through the through-hole and hooked onto a hanging member provided in the bathroom. With this configuration, the hooking member can be easily hooked onto the hanging member provided in the bathroom rather than directly hooking the through-hole onto the hanging member provided in the bathroom, improving usability in a sheet bathtub. [6] A bathroom equipped with a hanging member for hanging a bathtub described in any of [1] to [5] above.

[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] The bathtub 10 comprises a bathtub body 20 and a rope 30. The bathtub body 20 is made of a sheet. The bathtub 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 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] Folded portions 14 are formed on a pair of short sides 16 and a pair of long sides 17 (see Figure 4). As shown in Figure 3, the folded portions 14 are formed by folding the outer edge of the sheet material 13 to the outside of the bathtub body 20. The folded portion of the sheet material 13 is folded in three and sewn. The folded portions 14 are tubular and extend along the upper edge 15 of the bathtub body 20. The step created by forming the folded portions 14 is formed on the outside of the bathtub body 20.

[0023] The bathtub body 20 has an insertion section 25 and an engagement section 26. The insertion section 25 is a folded section 14 provided along the long side 17 of the upper edge section 15 of the bathtub body 20. The insertion section 25 is cylindrical. The rope 30 is inserted into the insertion section 25.

[0024] The insertion section 25 is formed continuously along the entire length of the long side 17 of the upper edge 15 of the bathtub body 20. The insertion section 25 has a double structure formed by folding back the sheet material 13, and therefore functions to reinforce the upper edge 15 of the bathtub body 20 together with the rope 30. When in use, the long side 17 of the upper edge 15 of the bathtub body 20 is less likely to bend downward. This allows the bathtub body 20 to maintain its boat-shaped shape without providing the rope 30 on the short side 16, and allows the bathtub body 20 to hold a sufficient amount of hot and cold water.

[0025] As shown in FIG. 4, the insertion portion 25 has a wide portion 27. The wide portion 27 is provided at both longitudinal ends of the insertion portion 25. The wide portion 27 constitutes the engagement portion 26. The width dimension of the wide portion 27 is larger than the width dimension of other portions of the insertion portion 25. The wide portion 27 is formed by making the folding margin of the sheet material 13 larger than that of other portions of the insertion portion 25. The width dimension of the wide portion 27 increases from the center toward the end in the extension direction of the long side 17. The wide portion 27 makes the engagement portion 26 less likely to stretch.

[0026] As shown in FIG. 2, the engagement portions 26 are provided at the four corners of the upper edge portion 15 of the bathtub main body 20. The engagement portions 26 are hooked onto hanging members 70 provided on the walls W1 and W2. As shown in FIG. 4, the engagement portions 26 are formed with through holes 28. The through holes 28 are circular. The through holes 28 penetrate both of the two sheets 13 stacked in the wide portion 27. The two sheets 13 are sewn together at the periphery 29 of the through holes 28. This closes the gap between the interior of the wide portion 27 and the through holes 28 at the periphery 29 of the through holes 28. The periphery 29 of the through holes 28 may be sewn with a buttonhole or the like. For example, the periphery 29 of the through holes 28 may be sewn with a chrysanthemum eyelet stitch, which is an overlock stitch resembling the petals of a chrysanthemum. By applying the eyelet stitching, the peripheral edge 29 of the through-hole 28 can be reinforced and the appearance can be improved.

[0027] The engagement portion 26 has a looped rope 18 as a hooking member. The looped rope 18 passes through the through hole 28. The looped rope 18 is hooked onto the hanging member 70. The bathtub body 20 is hung from the hanging member 70 via the looped rope 18. The looped rope 18 can be easily replaced.

[0028] As shown in Figure 2, the rope 30 is arranged along the upper edge 15 of the bathtub body 20 when in use. The rope 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. A polyester rope may be used for the rope 30. The rope 30 runs the entire length of the insertion section 25 from the wall W1 side to the wall W2 side. When in use, the rope 30 is stretched between the walls W1 and W2 via the loop rope 18.

[0029] As shown in FIG. 4, 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 and securing them with stop portions 32. The stop portions 32 may be sewn using sewing thread. The loop portions 31 are housed in the wide portion 27 and form the engagement portion 26. The loop portions 31 surround the entire circumference of the through hole 28 in the wide portion 27. A portion of the loop portions 31 is positioned above the through hole 28 in the wide portion 27 when in use. The entire rope 30, including the loop portions 31, is housed in the insertion portion 25 and is not exposed to the outside. This makes it difficult for the rope 30 to get dirty and makes it difficult for water to enter the insertion portion 25 along the rope 30.

[0030] An example of a method for bathing using bathtub 10 will be described below. First, the bather installs bathtub 10 in bathroom 50. Specifically, the bather installs bathtub 10 by hooking hooking portion 26 of bathtub main body 20 onto hanging member 70 of bathroom 50. Bathtub 10 is hung from walls W1, W2 of bathroom 50 via looped rope 18. The bather can easily install bathtub 10 in bathroom 50 by simply hooking hooking portion 26 onto hanging member 70.

[0031] 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.

[0032] 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 most of the weight of the bather are 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. Because rope 30 does not enter short side 16 of bathtub body 20, the bather only feels the softness of the fabric when placing their head or legs on short side 16 of bathtub body 20, allowing them to relax while bathing.

[0033] 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 looped rope 18 of 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.

[0034] The embodiment configured as described above provides the following effects. The bathtub 10 comprises a bathtub body 20 made of sheet 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 15 of the bathtub body 20 while suspended. The upper edge 15 of the bathtub body 20 is provided with an insertion section 25 into which the rope 30 is inserted. A through hole 28 is formed in the insertion section 25. The peripheral portion 29 of the through hole 28 closes the gap between the interior of the insertion section 25 and the through hole 28. When suspended, the rope 30 passes through the interior of the insertion section 25 above the through hole 28.

[0035] With this configuration, when the bathtub body 20 is suspended by hooking the through-hole 28 onto a hanging member 70 or the like installed in the bathroom, the load on the bathtub body 20 is borne by the rope 30 passing above the through-hole 28, making the part hooked onto the hanging member 70 less likely to stretch than when the load is borne by the bathtub body 20 alone. The periphery 29 of the through-hole 28 closes the gap between the inside of the insertion part 25 and the through-hole 28, preventing water from entering the inside of the insertion part 25 from the through-hole 28, making it easier to keep clean. This improves usability of the sheet-made bathtub 10.

[0036] The rope 30 has a loop portion 31 that goes around the through hole 28. With this configuration, the loop portion 31 is held at the position of the through hole 28, so that displacement of the rope 30 in the extension direction can be suppressed.

[0037] The peripheral portion 29 of the through-hole 28 is closed by sewing. If the peripheral portion of the through-hole is closed by metal fittings such as grommets, the joint between the metal fittings and the insertion portion may be damaged over time. If the peripheral portion of the through-hole is closed by welding, the welding may peel off over time. Because the peripheral portion 29 of the through-hole 28 is closed by sewing, durability can be improved compared to when metal fittings or the like are used.

[0038] When viewed from above in use, the upper edge 15 of the bathtub body 20 is rectangular. The insertion section 25 is provided along the long side 17 of the upper edge 15 of the bathtub body 20. The rope 30 extends along the long side 17 of the upper edge 15 of the bathtub body 20. This configuration makes it difficult for the long side 17 of the upper edge 15 of the bathtub body 20 to sag when in use, thereby maintaining the amount of water that can be stored in the bathtub body 20.

[0039] The bathtub 10 is equipped with a looped rope 18. The looped rope 18 is passed through the through-hole 28 and hooked onto a hanging member 70 provided in the bathroom 50. With this configuration, the looped rope 18 is easier to hook onto the hanging member 70 than if the through-hole 28 were directly hooked onto the hanging member 70 provided in the bathroom 50, making the bathtub 10 easier to use.
