DETAILED DESCRIPTION
First Embodiment
[0049] A first embodiment embodying a room of the present disclosure will be described with reference to the drawings. In the present embodiment, a shower room is exemplified as a room 1. As illustrated in FIG. 1, the room 1 is generally a room used for showering. As illustrated in FIG. 2, when a bathtub 10 is installed, the room 1 can be used as a bathroom for bathtub bathing. That is, the room 1 can be used as the bathroom by attaching the bathtub 10, and can be used as the shower room, which is an application other than the bathroom by removing the bathtub 10.
[0050] As illustrated in FIGS. 1 and 2, the room 1 has a rectangular parallelepiped shape that is long in the vertical direction (up-down direction). As illustrated in FIG. 3, the room 1 is adjacent to a washroom B on one of its four sides in a plan view. The room 1 forms a space smaller than a space of the adjacent washroom B. Specifically, the specific size of the room 1 according to the present embodiment is about 1600 mm in width, about 1200 mm in depth, and about 2200 mm in height as viewed from the washroom B side. On the other hand, the washroom B forms a space, continuous with the room 1, having a width and a height equal to those of the room 1 and having a length of about 2000 mm.
[0051] As illustrated in FIGS. 1 and 2, the room 1 includes walls W1, W2, and W3, a ceiling C, and a floor F. The room is surrounded by the walls W1, W2, and W3 on three sides in a plan view, except for the one side adjacent to the washroom B. The room 1 is closed by the ceiling C and the floor F on the upper side and the lower side, respectively.
[0052] The upper surface of the floor F extends substantially flush with the floor surface of the washroom B. The upper surface of the floor F is formed to be substantially flat. The floor F has a slight water gradient so that hot water or water flows toward a drain port (not illustrated). The walls W1 and W2 are connected to the walls of the washroom B substantially flush with them.
[0053] As illustrated in FIGS. 1 to 3, the room 1 includes a partition P. The partition P partitions between the room 1 and the washroom B in a openable and closable manner. The partition P can be opened over substantially the entirety of the width of the room 1. When the partition P is open, the room 1 and the washroom B form one continuous space having a rectangular shape in a plan view.
[0054] As illustrated in FIGS. 1 to 3, the room 1 includes a shower device 2. The shower device 2 is disposed on the wall W1 among the walls W1, W2, and W3. The shower device 2 is disposed on the wall W1 at a position close to the wall W3. The shower device 2 includes a water faucet 3, an overhead shower 4, and a hand shower 5. The water faucet 3 is formed in an elongated cylindrical shape extending in the horizontal direction along the wall surface of the wall W1. The water faucet 3 is connected to a water supply pipe and a hot water supply pipe (not illustrated) in the wall W1. The water faucet 3 is a mixing water faucet. The water faucet 3 is capable of adjusting an amount of water, adjusting a temperature by mixing hot water and water, discharging and stopping water, and the like. In the present specification, hot water or water supplied from a water faucet disposed in a room is referred to as hot water regardless of a temperature, a mixing ratio, or the like.
[0055] As illustrated in FIG. 4, the water faucet 3 is formed with a water discharge port 3A. The water discharge port 3A is formed in an elongated slit shape along the axial direction of the water faucet 3. A flow of water discharged from the water discharge port 3A forms a horizontally long thin-film form. The water faucet 3 can discharge hot water from the water discharge port 3A into the bathtub 10 in the state where the bathtub 10 to be described below is attached in the room 1. The water faucet 3 can discharge hot water through any one of the water discharge port 3A, the overhead shower 4, and the hand shower 5 selected.
[0056] As illustrated in FIGS. 1 and 2, the overhead shower 4 is provided above the water faucet 3. The overhead shower 4 is connected to the water faucet 3 through a pipe 6. The pipe 6 extends vertically upward along the wall surface of the wall W1 from the water faucet 3, and has the upper end bent toward the inner side of the room 1. The overhead shower 4 is provided at a distal end portion of the pipe 6. The hand shower 5 is connected to the water faucet 3 via a hose 7. The hand shower 5 is used while being movable in a range defined by the length of the hose 7.
[0057] The bathtub 10 described below is attached to the walls W1, W2, and W3 of the room 1. In the case of the present embodiment, the bathtub 10 is attached to the pair of walls W1 and W2 located left and right as viewed from the washroom B side, among the three walls W1, W2, and W3. The bathtub 10 is disposed at a position closer to the wall W3 than to the partition P (washroom B). As illustrated in FIG. 3, in the state where the bathtub 10 is attached to the pair of walls W1 and W2, a space that can be used as a washing place is formed on the partition P side as viewed from the bathtub 10.
[0058] Each of the pair of walls W1 and W2 has an attachment member 20. Part of the bathtub 10 is hooked and attached to the attachment member 20. In the case of the present embodiment, the attachment member 20 has a hook shape, that is, a shape of the letter J in a side view with the upper side open, and is fixed to each of the walls W1 and W2. As illustrated in FIG. 4, on the wall W1 side, two attachment members 20 are arranged below the water faucet 3 at an interval in the horizontal direction. On the wall W2 side, two attachment members 20 are arranged at the same height and at the same interval as the attachment members 20 on the wall W1 side. Thus, in the present embodiment, a total of four attachment members 20 are provided, that is, two attachment members 20 are provided on each of the pair of walls W1 and W2. The bathtub 10 is attached to an attachment portion 21 which corresponds to the hook shaped portion of the attachment member 20. A bathtub-side attachment portion 10A of the bathtub 10 described below is detachably attached to the attachment portion 21.
[0059] The bathtub 10 is detachably attached to the pair of walls W1 and W2 facing each other, among the walls W1, W2, and W3. As illustrated in FIG. 5, the bathtub 10 includes the bathtub-side attachment portions 10A. The bathtub-side attachment portions 10A are each detachably attached to the attachment members 20 provided on the walls W1 and W2. The bathtub-side attachment portion 10A corresponds to part of the bathtub according to the present disclosure, and is hooked and attached to the attachment member 20. The bathtub-side attachment portion 10A is provided in an upper edge portion of the bathtub 10. Thus, the bathtub 10 is suspended from the attachment members 20 at the upper edge portion. The bathtub 10 is deformed for holding hot water. The shape of the bathtub 10 can be freely changed to a folded state, a spread state, and the like.
[0060] The bathtub 10 of the present embodiment includes a sheet portion 11 and a rope 12. The sheet portion 11 holds hot water. The sheet portion 11 is made of a sheet. The sheet portion 11 is flexible. By cutting and joining etc. a flexible waterproof sheet, the sheet portion 11 is formed into a boat shape having a rectangular shape in a plan view. The sheet portion 11 of the present embodiment has low stretchability, and the boat shape is retained to a certain extent in the state where hot water is stored therein.
[0061] The rope 12 is provided annularly along the upper edge portion of the sheet portion 11. In the state where the bathtub 10 is installed, the sheet portion 11 is suspended by its outer edge portion from the rope 12. The rope 12 constitutes the bathtub-side attachment portion 10A. The rope 12 also functions as a reinforcing portion for reinforcing the sheet portion 11. With this configuration, the sheet portion 11 has a boat shape with the outer edge portion serving as the upper edge portion and with a central portion recessed downward. In the state where hot water is stored therein, a central part of the lower surface of the sheet portion 11 comes into contact with the floor F of the room 1. Thus, most of the load of the bathtub 10 filled with hot water can be supported on the floor F. As a result, a reinforcement structure of the walls W1 and W2 can be simplified as compared with a case where the bathtub 10 is supported only on the walls.
[0062] As illustrated in FIG. 6, the rope 12 is inserted into a folded portion 11A at the upper edge of the sheet portion 11. The folded portion 11A is formed by folding the outer edge portion of the sheet portion 11 into a tubular shape. The folded portion 11A is formed over the entire circumference of the upper edge portion of the sheet portion 11. The folded portion 11A is cut at four corners of the bathtub 10 having a rectangular shape in a plan view. The rope 12 is exposed to the outside at the four corners of the sheet portion 11. The rope 12 thus exposed from the sheet portion 11 is hooked on the attachment portion 21 having a hook shape, whereby the bathtub 10 is detachably attached to the walls W1 and W2. Since the folded portion 11A is folded to form a double structure, the folded portion 11A also functions as the reinforcing portion in the upper edge portion of the sheet portion 11.
[0063] As illustrated in FIG. 5, the bathtub 10 of the present embodiment includes a drainage portion 13. The drainage portion 13 is formed by providing an opening in a lower portion of the sheet portion 11, which can be opened and closed by a waterproof slide fastener. Thus, the hot water stored in the bathtub 10 can be easily discharge to the outside of the bathtub 10.
[0064] Advantageous effects of the room 1 having the above configuration will be described. In a normal state, that is, in the state where the bathtub 10 is not attached (the state where the bathtub 10 is removed), the room 1 can be used for showering a shower with the entire floor F serving as a washing place as illustrated in FIG. 1. The room 1 can be used for showering using at least one of the overhead shower 4 and the hand shower 5 of the shower device 2. In the room 1, the user can enjoy showering comfortably with a plenty of room in a space with a width of 1600 mm and a depth of 1200 mm, which is larger than general known shower rooms and washing places. When taking a shower in the state where the bathtub 10 is removed, no bubble or hot water attaches to the bathtub 10 in the room 1. Therefore, the room 1 can be easily cleaned after showering.
[0065] The room 1 can be used not only for daily showering, but also can be used for bathtub bathing as a pleasure for a special occasion. When the room 1 is used for bathtub bathing, the bathtub 10 is attached to the walls W1 and W2 as illustrated in FIG. 2. The bathtub 10 is detachably attached to the walls W1 and W2. The bathtub 10 is a sheet that is deformable between the folded state and the spread state. Thus, the bathtub 10 can be extremely easily installed and stored. At the time of installation, the bathtub 10 can be installed in a simple manner, specifically, by attaching the rope 12 exposed at the four corners, which serves as the bathtub-side attachment portion 10A, to the attachment portions 21 of the walls W1 and W2.
[0066] In the state where the bathtub 10 is installed, the water faucet 3 of the shower device 2 is used to fill the bathtub 10 with hot water. As illustrated in FIG. 4, the water faucet 3 can discharge hot water in a thin-film form from the water discharge port 3A. In the bathtub bathing using the bathtub 10, the hot water in a thin-film form discharged from the water discharge port 3A can be poured onto the neck or shoulder of the user inside the bathtub 10. The user can fill the bathtub 10 with hot water while hot water from the water discharge port 3A is being poured onto the user. The bathtub 10 is deformable and thus can be shaped to fit the user's body. This means that the amount of hot water needed to fill the bathtub 10 can be made small as compared with a non-deformable bathtub.
[0067] In the state where the bathtub 10 is filled with hot water, each part of the bathtub 10 is subject to the force by water pressure of the hot water stored therein. With the water pressure thus applied, the parts of the bathtub 10 are deformed, and the sheet portion 11 and the rope 12 are stretched. In particular, the rope 12 forming the upper edge portion of the bathtub 10 is firmly stretched so as not to be largely deflected even when a hand is placed thereon. Thus, the bathtub 10 is deformable but the deformation is suppressed by storing hot water therein, so that the shape can be stably maintained when the user gets in and out of the bathtub 10.
[0068] In the state where the bathtub 10 is filled with hot water, the lower surface of the central portion of the bathtub 10 comes into contact with the floor F. With the lower surface of the bathtub 10 thus coming into contact with the floor F, the weight of hot water stored in the bathtub 10 and the weight of the user are favorably supported on the floor F. This prevents excessive load from being applied to the attachment portion 21. Thus, according to the room 1, the reinforcement structure of the walls W1 and W2 where the attachment portions 21 are provided can be made simple as compared with, for example, a structure in which the bathtub is supported only on the wall and the ceiling.
[0069] When the bathtub bathing ends, the hot water stored in the bathtub 10 is drained from the drainage portion 13, and then the bathtub 10 is removed from the walls W1 and W2. Specifically, in the case of the present embodiment, the fastener of the drainage portion 13 is opened to drain the hot water, and then the rope 12, which is the bathtub-side attachment portion 10A, is detached from the attachment portion 21. The bathtub 10 removed is washed, dried, and folded to be stored. Unlike known stationary bathtubs, the bathtub 10 is detachable, and thus the entirety of the inner and the outer surfaces of the bathtub 10 can be washed. The bathtub 10 is made of a flexible and deformable sheet material, and thus can be washed, dried, or folded, like laundry. Once the bathtub 10 is removed, the entirely flat floor F appears in the room 1. Thus, the floor F of the room 1 can be easily cleaned, and thus can be cleanly maintained. The bathtub 10 is flexible and deformable, and therefore, it is possible to bathe in a desired posture, for example, by arranging a chair, a bench, a cushion, or the like between the bathtub and the floor F. A massage device or a heater may be arranged between the bathtub 10 and the floor F. Since these devices are arranged outside the bathtub 10, they do not need to be waterproof.
[0070] The bathtub 10 is made of a flexible sheet, and thus can be easily manufactured at a low cost as compared with a known bathtub made of FRP or the like. Therefore, it is relatively easy to provide a custom made bathtub 10 for a user. In this case, the size, design, and the like of the bathtub 10 can be freely set according to the user. The bathtub 10 is advantageous in terms of transportation cost, recyclability, and the like as compared with a known stationary bathtub made of FRP or the like. Therefore, the bathtub 10 can reduce environmental load. It is relatively easy for one user to own a plurality of such bathtubs 10. In this case, the user can select and use a desired one from the plurality of bathtubs 10 according to his or her mood, season, and the like, like selecting what to wear.
[0071] The bathtub 10 is attachable and detachable, which can also contribute to barrier freeness. For example, the bathtub 10 before attachment to the attachment members 20 is laid on the floor F. In this state, the user gets on the bathtub 10. Then, the bathtub-side attachment portions 10A of the bathtub 10 are attached to the attachment members 20 and then the bathtub 10 is filled with hot water. In this way, the user can bathe in the bathtub 10 without stepping over the upper end edge of the bathtub 10. According to such a way of bathing, a user who has difficulty in stepping over the upper end edge of the bathtub 10 as well as a user in a wheelchair can also easily bathe in the bathtub.
[0072] As illustrated in FIG. 7, when the partition P is open, a single space can be formed with the room 1 and the washroom B being continuous. The space thus formed is a space larger than the space formed by the room 1 only. The space thus formed can be used for multiple purposes, that is, for applications requiring a larger space, such as a fitness room and a laundry room.
[0073] As described above, the room 1 according to the first embodiment includes the walls W1, W2, and W3 and the ceiling C. In the room 1, the bathtub 10 is detachably attachable to the walls W1 and W2, among the walls W1, W2, and W3 and the ceiling C. The room 1 is used as a bathroom by attaching the bathtub 10. The room 1 is used as a shower room, which is an application other than the bathroom, by removing the bathtub 10.
[0074] The room 1 is a room for showering, but can be used as a bathroom which is a room for bathtub bathing by attaching the bathtub 10. When the room 1 is used for showering, the bathtub 10 is removed, whereby a wide space can be formed. That is, in the room 1, the bathtub 10 is attached only when the bathtub 10 is required, and for purposes not requiring the bathtub 10, the room 1 can be used with high spatial efficiency due to the absence of the bathtub 10. The room 1 is preferably a waterproof space with a waterproof pan used for the floor. In such a case, since the room is a waterproof space, the room can be used not only as a shower room, but also can be used for various purposes, such as maintenance of house plants and hot yoga.
[0075] The openable and closable partition P is provided between the room 1 and the washroom B which is another room adjacent thereto. When the partition P is open, the room 1 and the washroom B are used together as a single space. Thus, the room 1 can form a space larger than the space of the room 1 only. Therefore, the room 1 can be used in further different applications requiring a wider space, and thus has excellent versatility.
[0076] The bathtub 10 according to the first embodiment can be favorably attached in the room 1.
Second Embodiment
[0077] A room according a second embodiment is described with reference to the drawings. A room 201 according to the second embodiment is the same as that of the first embodiment in that the room is a shower room generally used for showering. The room 201 is different from the room 1 of the first embodiment in a configuration for attaching the bathtub 10. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals, and redundant description will be omitted.
[0078] As illustrated in FIG. 8, the room 201 according to the second embodiment includes a water faucet 203 serving as an attachment member and an attachment member 220. The water faucet 203 is attached to the wall W1. As illustrated in FIG. 9, the water faucet 203 has the same configuration as the water faucet 3 of the first embodiment, except that an attachment portion 221 is provided. That is, the water faucet 203 is formed with the water discharge port 3A having an elongated slit shape along the axial direction of the water faucet 203, and discharges a discharge water flow in a laterally long thin-film form. The attachment portions 221 are provide at both end portions of the water faucet 203 in a longitudinal direction. The attachment portion 221 is formed by reducing a diameter of a circumference wall of the cylindrical water faucet 203 in a form of a groove. The attachment portions 221 at both end portions of the water faucet 203 sandwich the water discharge port 3A therebetween.
[0079] The attachment member 220 is attached to the wall W2. As illustrated in FIG. 10, the attachment member 220 has a shape resembling the water faucet 3. Specifically, the attachment member 220 is formed in an elongated cylindrical shape extending in the horizontal direction along the wall surface of the wall W2. The attachment portion 221 of the attachment member 220 has the same configuration as the attachment portion 221 of the water faucet 203. That is, the attachment portions 221 of the attachment member 220 are provided at both end portions of the attachment member 220 in the longitudinal direction, and are formed by reducing the diameter of the circumference wall of the attachment member 220 in the circumference direction in a form of a groove. The attachment member 220 may be used as a handrail for getting in the bathtub.
[0080] As in the first embodiment, in the room 201 according to the second embodiment with the above configuration, the bathtub 10 is attached only when the bathtub 10 is required, such as for bathtub bathing, and for purposes not requiring the bathtub 10, the room 201 can be used with high spatial efficiency due to the absence of the bathtub 10. In the room 201, the water faucet 203 is provided as the attachment member on the wall W1 side, whereby the number of members functioning only as the attachment member can be reduced. Thus, the room 201 can have a tidy design as a whole. In the room 201, the attachment member 220 on the wall W2 side has a shape resembling the water faucet 203, whereby the two attachment members have balanced design so that tidy appearance can be achieved.
Third Embodiment
[0081] As illustrated in FIG. 11, a room 301 according to a third embodiment is different from each of the above-described embodiments in that the bathtub 10 is suspended from the ceiling C. In the following description, the same components as those in the embodiments described above are denoted by the same reference numerals, and redundant description will be omitted.
[0082] As illustrated in FIG. 11, the room 301 is the same as that of the second embodiment in that the water faucet 203 is provided as the attachment member on the wall W1 side. The room 301 is different from that of the second embodiment in that another attachment member 320 is provided on the ceiling C, not on the wall W2. That is, in the present embodiment, the bathtub 10 is detachably attachable to the wall W1 and the ceiling C.
[0083] The attachment member 320 is formed in an elongated cylindrical shape similar to that of the attachment member 220 of the second embodiment. Similarly, attachment portions 321 are formed in a form of grooves at both end portions of the attachment member 320 in the longitudinal direction. The attachment member 320 is connected to a lower end of a rope 322 suspended from the ceiling C. An upper end portion of the rope 322 is connected to a reinforcement structure, a building framework, or the like (not illustrated) on the ceiling or behind the ceiling, and ensures adequate strength for suspending the bathtub 10.
[0084] As in the first embodiment, in the room 301 according to the third embodiment with the above configuration, the bathtub 10 is attached only when the bathtub 10 is required, and for purposes not requiring the bathtub 10, the room 301 can be used with high spatial efficiency due to the absence of the bathtub 10. In the room 301, the water faucet 203 is provided with the attachment portions 221, whereby the room 301 can have a tidy design. In the room 301, the bathtub 10 is suspended from the attachment member 320 provided on the ceiling C. Thus, when the room 301 is used as a bathroom with the bathtub 10 installed therein, the suspended bathtub can offer an extraordinary experience.
[0085] According to the configuration in which the bathtub 10 is attached to the wall and the ceiling as in the room 301, a higher degree of freedom in the installation direction of the bathtub can be achieved as compared with a case where the bathtub is attached to the walls only. For example, when the bathtub is attached to a pair of walls facing each other as in the embodiments described above, the pair of walls need to face each other with an appropriate distance therebetween. On the other hand, the bathtub attached to the wall and the ceiling can be installed regardless of the distance between walls. For example, according to the configuration in which the bathtub is attached to the wall and the ceiling, the bathtub can be attached to a wall that does not face another wall, such as the wall W3 of the room 301.
Fourth Embodiment
[0086] As illustrated in FIG. 12, a room 401 according to a fourth embodiment is different from that of the third embodiment in that the bathtub 10 as a whole is suspended from the ceiling C using one attachment member 420, and other points are the same as those in the third embodiment. The attachment member 420 is formed in an elongated cylindrical shape longer than the attachment member 320 of the third embodiment, and has both end portions provided with attachment portions 421. In the present embodiment, all of the bathtub-side attachment portions 10A at four portions of the bathtub 10 are attached to any of the attachment portions 421 at both end portions of the attachment member 420. In the room 401, the bathtub 10 is configured so as not to come into contact with the floor F even when the bathtub 10 is filled with hot water. The attachment member 420 is connected to the ceiling C using a rope 422. The rope 422 has a lower end portion bifurcated to be connected to both end portions of the attachment member 420. Thus, as compared with the attachment member 320 of the third embodiment, the attachment member 420 has improved stability against inclination.
[0087] As in the first embodiment, in the room 401 according to the fourth embodiment with the above configuration, the bathtub 10 is attached only when the bathtub 10 is required, and for purposes not requiring the bathtub 10, the room 301 can be used with high spatial efficiency due to the absence of the bathtub 10. Since the bathtub 10 is attached in a suspended manner using one attachment member 420, the room 401 can have a tidy design. In the room 401, the bathtub 10 does not come into contact with the floor F even when the bathtub 10 is filled with hot water. Therefore, during bathtub bathing in the room 401, the user can enjoy the bathtub bathing providing extraordinary feeling as if he or she is floating.
Fifth Embodiment
[0088] As illustrated in FIG. 13, a room 501 according to a fifth embodiment is different from that of each of the above-described embodiments in that the bathtub 10 is attached to an attachment member 520 provided on the floor F. In the following description, the same components as those in the embodiments described above are denoted by the same reference numerals, and redundant description will be omitted.
[0089] As illustrated in FIG. 13, the room 501 includes the water faucet 203 serving as an attachment member and the attachment member 520. As illustrated in FIG. 14, the attachment member 520 is formed in an elongated cylindrical shape similar to that of the attachment member 220 of the second embodiment. The attachment member 520 is also similar to the attachment member 220 in that both end portions in the longitudinal direction are formed with attachment portions 521 in a form of grooves. The attachment member 520 is attached to an upper end portion of a frame body 522. The frame body 522 is movably installed on the floor F.
[0090] As in the first embodiment, in the room 501 according to the fifth embodiment with the above configuration, the bathtub 10 is attached only when the bathtub 10 is required, and for purposes not requiring the bathtub 10, the room 501 can be used with high spatial efficiency due to the absence of the bathtub 10. When the bathtub 10 is removed, the attachment member 520 provided with the attachment portions 521 also can be moved to a desired position. Thus, the room 501 can be used with even higher spatial efficiency, when used for purposes not requiring the bathtub 10.

[0098] The configuration of the bathtub-side attachment portion according to the present disclosure is not limited to the embodiments described above. The bathtub-side attachment portion may be part of the sheet portion, or may be a member different from the sheet portion, such as a rope. The bathtub-side attachment portion may have various forms, for example, a hook shape and a bag shape, in addition to the annular form and the tubular form exemplified in the above embodiments. The bathtub-side attachment portion may be attached to the attachment member via another member such as a rope, for example. The number of the bathtub-side attachment portions is not limited to those in the above embodiments. For example, the bathtub-side attachment portion may be preferably provided at three or more portions. In such a case, the bathtub can be stably attached.
[0099] The number, the configuration, and the like of the attachment portions according to the present disclosure are not limited to the above embodiments. For example, the number of the attachment portions provided may be larger than that of the bathtub-side attachment portions. In this case, when attaching the bathtub, some of the plurality of attachment portions are selected to attach the bathtub-side attachment portion, whereby the arrangement, shape, and the like of the bathtub can be selectively changed according to user's preference and the like. The attachment portion is not limited to the hook shape, the groove shape, and the like exemplified in the embodiments described above, and can be in various forms, for example, a bar shape or an annular shape.
[0100] The attachment member according to the present disclosure may be in a form as illustrated in FIG. 15, for example. In FIG. 15, an attachment member 620 includes an attachment portion 621. The attachment portion 621 is provided between both end portions of the attachment member 620 having an elongated cylindrical shape. For example, as illustrated in FIG. 15, the attachment member 620 may be detachably supported by two annular ropes 622 at its groove shaped portions formed in both end portions in the longitudinal direction. As illustrated in FIG. 15, the two annular ropes 622 may be suspended from a suspension member 623, for example. The suspension member 623 is formed in a hanging ring form, with an annular ring provided at a lower end of a bar-shaped portion suspended from the ceiling C. An upper end portion of the suspension member 623 is connected to a reinforcement structure, a building framework, or the like (not illustrated) on the ceiling or behind the ceiling. The suspension member 623 may be attached to the wall, for example, not limited to the ceiling.
[0101] The bathtub may have a bathtub-side attachment portion 610A as illustrated in FIG. 15, and may be attached to the attachment portion 621 of the attachment member 620 with the above configuration. The bathtub-side attachment portion 610A is in a tubular form formed by folding an end portion of a bathtub 610 in a longitudinal direction. The bathtub-side attachment portion 610A is attached to the attachment portion 621, with the attachment member 620 inserted therethrough in the axial direction from one end side. The attachment member 620 also functions as a reinforcement member for reinforcing the bathtub 610.
[0102] The attachment member according to the present disclosure may be in a form as illustrated in FIG. 16, for example. In FIG. 16, an attachment member 720 includes an attachment portion 721. Similarly to the attachment portion 621 described above, the attachment portion 721 is provided between both end portions of the attachment member 720 having an elongated cylindrical shape. The attachment member 720 is supported by support portions 722, which are respectively provided on a pair of facing walls, at its groove shaped portions formed in both end portions in the longitudinal direction, for example. As illustrated in FIG. 17, the support portion 722 has a rectangular parallelepiped box shape with the upper side open, and has one surface formed with a notch-shaped portion into which an end portion of the attachment member 720 is inserted. The attachment member 720 is bridged between the pair of walls with both end portions supported by the support portions 722. In this state, the attachment member 720 is disposed along the longitudinal direction of a bathtub 710.
[0103] The bathtub 710 may be attached to the attachment portion 721 of the attachment member 720 with the above configuration, at its end portion in a transverse direction, that is, its long side in a plan view. The bathtub 710 includes a bathtub-side attachment portion 710A. The bathtub-side attachment portion 710A is formed by folding an end portion of the bathtub 710 in the transverse direction into a tubular shape. The bathtub-side attachment portion 710A is attached to the attachment portion 721, with the attachment member 720 inserted therethrough in the axial direction from one end. The attachment member 720 also functions as a reinforcement member for reinforcing the bathtub 710.
[0104] The attachment member according to the present disclosure may be in a form as illustrated in FIG. 18, for example. In FIG. 18, an attachment member 820 includes an attachment portion 821. The attachment portion 821 is provided between both end portions of the attachment member 820 having a circular columnar shape. The attachment member 820 may be supported by a rail member 822 at its both end portions in the longitudinal direction. The rail member 822 is a channel steel-shaped member having a substantially U-shaped cross section. The rail member 822 is provided to extend in the up-down direction along the wall surface. The rail members 822 has a plurality of holes 822A arranged in the up-down direction. The attachment member 820 is selectively inserted into the holes 822A. The user selects the holes 822A at a desired height and inserts the attachment member 820, to install a bathtub 810 at the desired height.
[0105] The attachment member 820 may have both end portions 820A bent into an L shape as illustrated in FIG. 18 and FIG. 19. The holes 822A are formed in a size into which the attachment member 820 can be inserted. Such a combination of the attachment member 820 and the holes 822A can provide a function of retaining the attachment member 820 in the holes 822A. The holes 822A may be formed in a long hole shape as illustrated in FIG. 19, for example. With this configuration, when removing the attachment member 820, the direction about the axis of the attachment member 820 is limited with respect to the holes 822A, and thus the retaining function can be more effectively provided.
[0106] The bathtub 810 is attached to the attachment member 820 with the above configuration, at a bathtub-side attachment portion 810A as illustrated in FIG. 18 and FIG. 19. The bathtub-side attachment portion 810A is formed by being folded at four corners of the bathtub 810 into a tubular shape. When attaching the bathtub 810, the bathtub-side attachment portion 810A is disposed in the groove of the rail members 822 at a height position corresponding to the desired holes 822A, and in this state, the attachment member 820 is inserted, from the side of the rail member 822, into the hole 822A, bathtub-side attachment portion 810A, and the hole 822A in this order.
[0107] The rail member may be in a form as illustrated in FIG. 20 and FIG. 21, for example. Similarly to the rail members 822, rail members 922 as illustrated in FIG. 20 and FIG. 21 have a plurality of holes 922A in the up-down direction. The holes 922A each have the inner circumference in a substantially circular shape. The holes 922A are connected via a slit 922B in the up-down direction. The slit 922B is formed to have a width smaller than the inner diameter of the holes 922A.
[0108] An attachment member 920 corresponding to such a rail member 922 has a circular columnar shape as illustrated in FIG. 21, and is inserted into any of the holes 922A of the rail members 922. An attachment portion 921 in the attachment member 920 is a portion between both end portions of the attachment member 920. The attachment member 920 has an outer diameter equivalent to the inner diameter of the holes 922A, and can be inserted into the holes 922A. Both end portions 920A of the attachment member 920A are each formed with a width across flats that is equivalent to the width of the slit 922B. With this configuration, the attachment member 920 can be moved in the rail member 922 in the up-down direction through the slit 922B, and attached to the desired holes 922A, without being removed from the rail member 922. Thus, the bathtub-side attachment portion 810A can be changed in height while being attached to the attachment portion 921. This configuration not only enables the bathtub to be changed to a desired height easily, but also is advantageous, for example, when draining hot water in the bathtub. That is, with the above configuration, hot water in the bathtub can be easily drained by simply lowing the height of one of the bathtub-side attachment portions 810A, without providing a drainage portion in the bathtub.
[0109] The attachment member according to the present disclosure may be provided in a configuration as illustrated in FIG. 22 and FIG. 23, for example. An attachment portion 1021 illustrated in FIG. 22 and FIG. 23 includes a first bar-shaped member 1020A and a second bar-shaped member 1020B serving as the attachment members. The first bar-shaped member 1020A and the second bar-shaped member 1020B extend parallel to the wall surface and in the horizontal direction, and are arranged side by side in the up-down direction. The first bar-shaped member 1020A is fixedly attached to the wall. The second bar-shaped member 1020B is provided above the first bar-shaped member 1020A so as to be movable in parallel in the up-down direction with respect to the first bar-shaped member 1020A. A bathtub 1010 illustrated in FIG. 22 is attached to the attachment portion 1021 at a bathtub-side attachment portion 1010A. Specifically, the bathtub-side attachment portion 1010A is clamped by the two bar-shaped members 1020A and 1020B in the up-down direction while being wound in an S shape, thereby being attached to the attachment portion 1021. In this case, the weight of the bathtub is applied in a direction that enhances the strength of clamping the bathtub-side attachment portion 1010A by the two bar-shaped members 1020A and 1020B, and thus the attachment can be more strongly implemented. As illustrated in FIG. 23, the bathtub-side attachment portion 1010A has a folded portion 1011A at its end portion. The folded portion 1011A of the bathtub-side attachment portion 1010A functions to prevent detaching from the attachment portion 1021.
[0110] The attachment member according to the present disclosure may be in a form as illustrated in FIG. 24 and FIG. 25, for example. In FIG. 24 and FIG. 25, an attachment member 1120 includes an attachment portion 1121. The attachment portion 1121 is an annular portion of the attachment member 1120. The bathtub-side attachment portion may be, for example, a bathtub-side attachment portion 1110A illustrated in FIG. 25. The bathtub-side attachment portion 1110A is formed by extending part of an upper end portion of a bathtub 1110 in an outward direction, and forming an extended end into a bag shape. A spherical body 1110B as illustrated in FIG. 25 is inserted in the bathtub-side attachment portion 1110A. The spherical body 1110B has an outer diameter larger than the maximum inner diameter of the attachment portion 1121 and has a certain degree of rigidity. When attaching the bathtub-side attachment portion 1110A to the attachment portion 1121, the bathtub-side attachment portion 1110A is inserted through the annular attachment portion 1121, and then the spherical body 1110B is put in the bag-shaped portion at the distal end. Thus, the spherical body 1110B is caught in the attachment portion 1121 and retained, whereby the state where the bathtub-side attachment portion 1110A is attached to the attachment portion 1121 is maintained.
[0111] The bathtub-side attachment portion in various forms can be attached to the annular attachment portion as described above. For example, a bathtub-side attachment portion 1210A as illustrated in FIG. 26 and FIG. 27 have the same configuration as the bathtub-side attachment portion 1110A described above, except that the distal end is not formed in a bag shape. The bathtub-side attachment portion 1210A is inserted through the annular attachment portion 1121, and then a distal end portion thereof is tied to a ring 1210B. Similarly to the spherical body 1110B, the ring 1210B has an outer diameter larger than the maximum inner diameter of the attachment portion 1121 and has a certain degree of rigidity. Thus, a state in which the bathtub-side attachment portion 1210A is attached to the attachment portion 1121 can be maintained. Such a bathtub-side attachment portion 1210A can also be attached by simply being tied to, for example, an annular attachment portion such as the attachment portion 1121, or a hook-shaped attachment portion. In this case, the shape of the bathtub can be adjusted only by changing the way of tying.
[0112] The attachment member may be in a form as illustrated in FIG. 28, for example. An attachment member 1320 in FIG. 28 can be detachably attached to a desired position on the wall by means of magnetic force. The attachment member 1320 is connected to a support member 1322 so as to be rotatable about an axis extending in the substantially horizontal direction. The support member 1322 is pivotally supported by the attachment member 1320 at its upper end portion. The support member 1322 has a shape of a bar extending downward from the attachment member 1320, and comes into contact with the floor F with a floor support portion 1322A provided in its lower end portion. Even when the angle of the support member 1322 with respect to the attachment member 1320 is changed in accordance with the height position of the attachment member 1320, the state where the floor support portion 1322A is in contact with the floor F can be maintained. For such an attachment member 1320, the attachment portion is not limited to the annular shape as illustrated in FIG. 28, but may be provided in various forms as described above.
[0113] The floor support portion 1322A is preferably provided with, for example, an anti-slip structure for the floor F. As the anti-slip structure, for example, a structure including a suction cup that adheres to the floor F, or a structure including a rubber or elastomer sheet material provided on a contact surface with the floor F, may be adopted. As the anti-slip structure, for example, as illustrated in FIG. 28, a plate-like anti-slip member F1 may be laid on the floor F, and the floor support portion 1322A may be brought into contact with an end portion of the anti-slip member F1. In this case, the anti-slip member F1 is preferably brought into contact with the central portion of the lower surface of the bathtub filled with hot water. This configuration can prevent positional displacement of the anti-slip member F1 itself, which can effectively prevent positional displacement of the floor support portion 1322A of the support member 1322 and the attachment member 1320 connected thereto.
[0114] The bathtub-side attachment portion may be in a form as illustrated in FIG. 29 and FIG. 30, for example. A bathtub-side attachment portion 1410A illustrated in FIG. 29 and FIG. 30 is formed by part of a sheet portion 1411. More specifically, the bathtub-side attachment portion 1410A is formed by a hole in an outer edge portion of the sheet portion 1411 of a bathtub 1410. A circumference edge portion of the hole is reinforced by an eyelet 1414. The portion of the sheet portion 1411 where the bathtub-side attachment portion 1410A is provided is reinforced by being folded and overlapped. Such a bathtub-side attachment portion 1410A can be attached to the hook-shaped attachment member 20 as in the first embodiment described above, as illustrated in FIG. 29 and FIG. 30.
[0115] The bathtub-side attachment portion may be in a form as illustrated in FIG. 31 and FIG. 32, for example. A bathtub-side attachment portion 1510A illustrated in FIG. 31 is provided in a bathtub-side attachment member 1514 attached to an outer edge portion of a sheet portion 1511 of a bathtub 1510. The bathtub-side attachment member 1514 may be formed as, for example, an integrally molded product made of resin or the like. As illustrated in FIG. 32, the bathtub-side attachment member 1514 includes an annular portion 1514A and a holding portion 1514B. The annular portion 1514A constitutes the bathtub-side attachment portion 1510A. The annular portion 1514A has a ring shape, and can be attached to an attachment member having a hook shape or the like. The holding portion 1514B is connected with the annular portion 1514A, and holds the outer edge portion of the sheet portion 1511. The holding portion 1514B clamps and holds the outer edge portion of the sheet portion 1511 with a plate-shaped member having a plurality of protrusions and another plate-shaped member having holes in which the protrusions are fitted. The two plate-shaped members of the holding portion 1514B are connected at their one end sides and can be opened and closed like a hinge through elastic deformation, for example. The portion of the outer edge portion of the sheet portion 1511 where the bathtub-side attachment member 1514 is attached is reinforced by being folded and overlapped. The bathtub-side attachment member 1514 may include a portion constituting a bathtub-side attachment portion in another form, instead of the annular portion 1514A, for example, a hook shape.
[0116] The bathtub-side attachment portion may be in a form as illustrated in FIG. 33 and FIG. 34, for example. A bathtub-side attachment portion 1610A illustrated in FIG. 33 and FIG. 34 is provided in a bathtub-side attachment member 1614 attached to an outer edge portion of a sheet portion 1611 of a bathtub 1610. As illustrated in FIG. 33 and FIG. 34, the bathtub-side attachment member 1614 has an elongated bar shape, and is undetachably attached to the sheet portion 1611 with an outer edge portion of the sheet portion 1611 wound around the bathtub-side attachment member 1614. Both end portions of the bathtub-side attachment member 1614 protrude from the outer edges of the sheet portion 1611 to be exposed. The bathtub-side attachment portion 1610A is provided in the both end portions of the bathtub-side attachment member 1614 exposed from the sheet portion 1611. The bathtub-side attachment portion 1610A is in a form of groove, and can be attached to an attachment member in a hook shape, an annular shape, or the like.
[0117] It is not essential for the bathtub according to the present disclosure to have a drainage portion. When the bathtub has a drainage portion, the configuration and the like of the drainage portion are not limited to those in the above embodiments. As the drainage portion, a drainage portion having various known plugs, such as a resin plug used for a swim ring or the like, a rubber plug used for a known bathtub, and a plug used for a water bottle, can be adopted.
[0118] The drainage portion may be in a form as illustrated in FIG. 35, for example. A bathtub 1710 is provided with a drainage portion 1713 as illustrated in FIG. 35. Unlike the above embodiments, an upper edge portion of the bathtub 1710 is formed only by a sheet portion 1711. In other words, the bathtub 1710 has no annular rope along the upper edge portion of the sheet portion 1711. The drainage portion 1713 includes a waterproof slide fastener as in the above embodiments. The fastener of the drainage portion 1713 is provided in an upper part of the sheet portion 1711. When the fastener of the drainage portion 1713 is slid downward, the upper edge portion of sheet portion 1711 can be opened in a separated manner.
[0119] As illustrated in FIG. 35, the lower end of the fastener of the drainage portion 1713 is set at a position slightly higher than the expected water level in the bathtub 1710. That is, the drainage portion 1713 is not submerged in the state where the bathtub 1710 is filled with a normal amount of hot water. Therefore, the drainage portion 1713 can avoid leakage of hot water regardless of the level of the waterproofness of the fastener. When the fastener is open, the sheet portion 1711 becomes slack due to an increase in the outer circumference length of the upper edge portion. Therefore, a certain amount of hot water in the bathtub 1710 can be discharged by the drainage portion 1713. The hot water remaining in the bathtub 1710 is discharged by detaching the bathtub 1710. The bathtub 1710 from which a certain amount of hot water has been discharged using the drainage portion 1713 is lighter than before the discharge, and thus can be easily detached. As described above, the bathtub 1710 has no annular rope along the upper edge portion of the sheet portion 1711. As another form, for example, the bathtub 1710 may be configured such that a rope is arranged only on the long side of the sheet portion 1711 for the purpose of reinforcement or for a bathtub-side attachment portion, and a fastener is provided in an upper part of the sheet portion 1711 on the short side where the rope is not arranged.
[0120] The drainage portion may be in a form as illustrated in FIG. 36, for example. A drainage portion 1813 as illustrated in FIG. 36 is integrally provided in a sheet portion 1811. The inner surface of the drainage portion 1813 adheres tightly with an adhesive material or the like, thereby closing the drainage portion 1813 so that water is not easily discharged from a pipe. When a bathtub 1810 is filled with hot water, the drainage portion 1813 is further pressurized and closed by water pressure, whereby the discharge of the hot water is prevented. By opening the drainage portion 1813 against the water pressure, the hot water in the bathtub 1810 can be discharged to the outside.
[0121] The drainage portion may be in a form as illustrated in FIG. 37, for example. A drainage portion 1913 as illustrated in FIG. 37 is integrally provided in a sheet portion 1911. The drainage portion 1913 is formed in a form of a pipe protruding out from a bathtub 1910. The drainage portion 1913 in a pipe form can be bent. The drainage portion 1913 is formed to have such a length that its distal end can be arranged above the water level when the bathtub 1910 is filled with hot water. The distal end portion of the drainage portion 1913 is arranged above the water level, which can prevent the hot water from being discharged, so that a state where the bathtub 1910 is filled with hot water can be maintained. By placing the distal end portion of the drainage portion 1913 below the water level, hot water in the bathtub 1910 can be easily discharged.
[0122] The drainage portion may be in a form as illustrated in FIG. 38, for example. A bathtub 2010 is provided with a drainage portion 2013 as illustrated in FIG. 38. In the drainage portion 2013, an opening 2013A formed in a bottom portion of a sheet portion 2011 is closed by a float valve 2013B. In the state where the bathtub 2010 is filled with hot water, the float valve 2013B can close the opening 2013A by means of water pressure. The float valve 2013B is connected to an operation lever 2013C attached to the wall surface via a ball chain. The float valve 2013B opens the opening 2013A in response to an operation of the operation lever 2013C. The float valve 2013B after opening the opening 2013A is maintained its state by buoyancy. Once the hot water in the bathtub 2010 is discharged, the opening 2013A is closed by the float valve 2013B again.
