Description

  The present invention is a bathroom as a system with a bathtub that helps bathing elderly people and physically disabled people and reduces the labor of a person who assists or cares. The fuel cost for suppressing the amount of hot water and boiling the hot water Energy-saving multi-function that can be installed easily, with no restrictions on installation location, with limited installation location and easy portability, and can be used not only for bathing but also for shower rooms and sauna baths. Regarding the bathroom.

  In general, the bathroom occupies a corner of the building, and when taking a bath, the bathroom moves to the bathroom and is so-called “take a bath”. For this reason, the bathroom is a non-movable part of the building as a general stereotype. Of course, temporary shared baths and mobile baths installed at evacuation shelters in the event of disasters are baths that can be disassembled, assembled, or moved, but are temporary baths for people who have encountered disasters, and for nursing care. The purpose of use is limited. The present inventor further sought a mobile bath that can be used for general purposes, and proposed a so-called “mobile bath where anyone can take a bath anywhere (although the use of hot water, etc. and drainage points are indispensable)”. To do. A portable mobile bath such as the present invention has not yet been proposed within the scope of the investigation. Even in countries where there is no custom of using hot water baths and there is a custom of washing the body with a shower, there is no portable shower room as at least the knowledge of the inventors.

  From another point of view, when focusing on the bathing of the elderly and the disabled, which has increased in the recent era of population decline, that is, the elderly, dementia, and disabled (who are referred to collectively as the elderly) ) And caregivers who bathe the elderly (collectively referred to as “assistants”), the mental and physical burdens and labor for both the elderly and the assistants are different from those of healthy people. Therefore, we would like to alleviate this burden and effort so that both elderly and caregivers can take a bath with peace of mind. Taking the above moving bathing car as an example, the structure is equipped with a conventional bathtub and is equipped with a hot water drainage system, and it is very helpful to be able to reduce the traveling time and distance of elderly people. However, when bathing for the elderly, it is inevitable that the elderly or the caregivers will spend a great burden and effort even if they have ancillary facilities. For this reason, in the past, many proposals have been made to reduce the burden of bathing of the elderly and the effort of the caregiver as much as possible, and the bathtub has a structure that allows the bathtub to expand and contract (JP-A-7-8400, There are various proposals such as a bathtub (JP-A No. 10-309303), a bathtub (JP-A 2002-85508) or a bathtub that can be disassembled and assembled (JP-A 2007-181590). is there.

  However, although there are many excellent proposals from the viewpoint of reducing the burden on the elderly and reducing the labor of the caregivers, that is, from the viewpoint that the elderly are easy to take a bath and the caregivers are a little easier, At the same time, from another viewpoint, a large amount of hot water is required for bathing by one person, and the fuel cost is increased. For example, bathing while riding in the above-described dedicated wheelchair not only requires a large amount of hot water, but also increases the weight and bulk of the bathtub, which makes it expensive. In other words, the above-mentioned portable baths that can be carried are not found, and a simple and inexpensive bathtub that can be controlled with a large amount of hot water and fuel is installed. And there is no bathroom as an effective and feasible system for reducing labor.

Japanese Patent Laid-Open No. 7-8400 JP-A-10-309303 JP 2002-85508 A JP 2007-181590 A JP 2009-330 A JP 2005-52247 A JP 2002-339413 A

  The present invention was invented in view of the above-mentioned problems, starting from the point of view of a movable bathroom and the burden of the elderly as much as possible, and helping the assistant to reduce the labor as much as possible, and the amount of hot water to be used Aiming at energy saving that leads to the suppression of global warming by suppressing fuel costs to boil hot water, and it can be carried without installing place, and the restriction and cost of installation place will be more gradual than before, Provide an energy-saving multifunctional bathroom that can be used not only for bathing but also for shower rooms and sauna baths.

  The configuration of the present invention that achieves the above object is a bathtub tubular body that cannot hold its own shape and is watertight and can be entered by a person, and surrounds the outside of the bathtub tubular body to form a fixed shape by injecting fluid. A rising step portion having a plurality of expansion and contraction bags to be planted together with the tubular body, a storage container for shrinking and storing the rising step portion and the bathtub tubular body, and the bathtub tubular body It has the supply part and discharge part which were connected from the outside.

  Moreover, the said bathtub cylindrical body has a structure which changes inner side space shape according to a bather's body shape and attitude | position.

  Furthermore, a plurality of types of switching valves and fluid supply / discharge devices are connected to the supply unit and the discharge unit, respectively.

  The bathtub itself can be extended and retracted and stored in a storage container, so it can be carried anywhere and can be carried anywhere, overcoming the concept of a conventional bath, and can supply and discharge minimum air and supply and discharge hot water, for example. It can be installed anywhere.

  The structure in which the start-up step and the tubular tubular body can be expanded and contracted brings about a significant reduction in the burden and labor of the elderly and caregivers, coupled with the fact that the bathtub can be carried.

  The bathtub tubular body itself has a structure that changes the shape of the inner space according to the body shape and posture of the bather, so the amount of hot water can be significantly reduced compared to conventional bathtubs, and the amount of water and fuel that boils hot water is reduced. It is possible to obtain an energy-saving bathroom.

  The piping of the bathtub itself can be freely connected, and it can be used as a multifunctional purpose-use bathroom in addition to a bath that warms the body if necessary, such as shower, sauna bath, hot air drying etc. It becomes.

  FIG. 1 thru | or FIG. 5 has shown an example of the bathtub used for the bathroom of this invention. This bathtub has a roughly box-shaped storage container 1, a rising step 2 that is shaped like a vertically stacked floating ring in a vertically stretchable state, and an inner space of the rising step 2. It consists of the bathtub cylindrical body 3 which is located in this and expands and contracts with expansion / contraction of this starting step part 2. As shown in FIG.

  The storage container 1 is, for example, a rectangular box as shown in FIG. 1 as viewed from above, and the rising step 2 and the bathtub cylindrical body 3 are stored by contraction of the rising step 2 as shown in FIG. It has a size and shape that can be made, and is lightweight so that it can be carried. In addition, the storage container 1 is required to have a strength to withstand the weight of water, humans, and the like when the bathtub is used. When weight is important, it is possible to configure the whole with a lightweight member, and to arrange a reinforcing member at a location where a load is partially applied. Further, the storage container 1 needs to have a so-called watertightness without water leakage because it is used indoors, regardless of only the outdoor use described later. Specifically, for example, a lightweight metal or plastic box having a length of 1.2 m, a width of 1.2 m, and a height of 0.4 m can be used. As shown in FIG. 4, the storage container 1 includes a handle 11, a caster 12, and a lid 13 that is convenient for storage. Inside the storage container 1 are an air supply / discharge unit 14 shown in FIG. 1, a supply unit 15 for hot water, a supply unit 16 for steam / hot air, a discharge unit 17, and a stirrer 18 shown in FIGS. Have In addition, as shown in FIGS. 1 to 3, the air supply / discharge part 14 is connected to five hoses 142 attached to a fluid supply / discharge bag, which will be described later, via a six-way electromagnetic valve 141. The supply unit 15 such as warm water is a supply pipe connected to the inside of the bathtub tubular body 3. The steam / warm air supply unit 16 is connected to the inside of the bathtub cylindrical body 3 through a two-way electromagnetic valve 161. The electromagnetic valve 161 and its outlet pipe are located higher than the drain outlet 171 of the discharge part 17 so that hot water does not accumulate inside them. The discharge part 17 is provided with a pipe connected to the drain outlet 171 at the bottom of the bathtub cylindrical body 3 via the three-way solenoid valve 173 and a pipe connected to the drain outlet 172 at the bottom between the bathtub cylindrical body 3 and the rising step part 2. . The six-way solenoid valve 141, the two-way solenoid valve 161, and the three-way solenoid valve 173 are directional switching valves based on electromagnetic force. However, the six-way switching valve can be switched by driving air or a machine, a push button, or the like, A two-way switching valve and a three-way switching valve may be used.

  The start-up step 2 has a size that fits into the storage container 1 as shown in FIGS. 1 to 3, and a so-called floating ring-shaped expansion bag (fluid supply / discharge) as shown in FIGS. 2 to 5. A plurality of bags 21) are stacked. The fluid supply / discharge bag 21 has a space in which the tubular tubular body 3 can be arranged on the inside, and the fluid filled in the bag does not leak, and is strong against deformation due to supply / discharge of fluid during use. Materials are selected. As a material, for example, a synthetic resin or vinyl chloride used for an air boat is used. Here, the fluid supply / discharge bag 21 is a bag that can supply and discharge the fluid and seal the fluid, and it is most convenient to use air as the fluid, but other gas or liquid such as water can be used. It can also be used. Furthermore, as a simple expansion and contraction bag, a material that does not supply and discharge fluid, such as the fluid supply and discharge bag 21, but compresses while applying a load to form a flat shape, and recovers to a floating ring shape when the load is removed is described later. A system using the same cloth-like structure and material as the bathtub tubular body 3 (FIG. 19) is also conceivable.

The example shown in FIGS. 2 and 3 shows a state in which ten fluid supply / discharge bags 21 are stacked, and two fluid supply / discharge bags communicating with each other form a set, and a stabilizing plate 22 is formed on the upper part. Placed and fixed. The stabilizing plate 22 has a size that fits into the storage container 1 like the fluid supply / discharge bag 21 and has a space in which the bathtub tubular body 3 can be disposed. One end of the stabilizing plate 22 is fixed to a hole described later of the upper stabilizing plate 22 and the other end is connected to the free end of a spring 231 having a fixed end attached to the lower stabilizing plate 22. It has the strip body 23 which consists of a length adjustment string or a wire. The lower stabilizer plate 22 has a spring 231 that does not extend a certain length or longer, and a stopper (not shown) for limiting the extension length of the strip 23 and the orientation of the strip 23 that can extend in the height direction is the horizontal direction. When the fluid supply and discharge bag 21 is contracted, for example, when the stabilizing plate 22 approaches, the spring 231 pulls the strip 23 in the lateral direction (horizontal direction) through the roller, When the fluid supply / discharge bag 21 expands in the height direction, for example, when the space between the stabilizing plates 22 expands, the spring 231 extends until it hits the stopper. Therefore, the height of the strip 23 connected to the spring 231 in a state having a roller for regulating the orientation of the strip 23 and a stopper for regulating the extension of the spring 231 is adjusted by the stopper when the fluid supply / discharge bag 21 is expanded. The spring 231 has a function of stably maintaining the horizontal level, and the contracted strip 23 of the spring 231 is pulled in the horizontal direction to be securely stored. 2 and 3, the stabilizing plate 22 is located above the second, fourth, sixth, eighth, and tenth fluid supply / discharge bags 21 from the bottom, and each of the stabilizing plates including the lowermost stabilizing plate 22. The strips 23 are located between the plates 22.

  The stabilizing plate 22 shown in FIG. 1 shows what is located on the uppermost fluid supply / discharge bag 21, but the stabilizing plate 22 has holes 221 for fixing the above-described strips 23 through the four corners. . The holes 221 are formed at all four corners of each stabilizing plate 22, and one end of the strip 23 is passed and fixed. The other end of the strip 23 is a spring 231 attached to the lower stabilizing plate 22 or the storage container 1. As described above, it is connected to the free end. The length of the strip 23 between the stabilizing plates 22 is set for height adjustment and stability in a state in which the fluid supply / discharge bag 21 is inflated. Further, the length of the strip 23 is set. The swelling of the fluid supply / discharge bag 21 below the stabilizing plate 22 is also suppressed, and the fluid supply to the fluid supply / discharge bag 21 further above is started by detecting an increase in internal pressure during fluid supply. That is, by detecting the fluid pressure (internal pressure) from the two lowermost fluid supply / discharge bags 21, the fluid is sequentially supplied to the upper two fluid supply / discharge bags 21, and the start-up step portion 2 is moved upward from the bottom. There is also to set up and plant while keeping the level. The start-up of the start-up step 2 will be further described with reference to FIG. In addition, when the fluid supply / discharge bag 21 stably expands in a predetermined shape, the stability plate 22 and the storage container 1 are not provided with the spring 231, the stopper, and the roller, and the stability from the bottom to the top A simple structure in which the stabilizers 22 up to the plate 22 are connected by the strips 23 through the holes 221 can also be adopted.

  In the example shown in FIGS. 2 and 3, the fluid supply / discharge bags 21 are connected in pairs, and each set includes a stabilizing plate 22 and a strip 23. The number of combinations and the number of stabilizing plates 22 and strips 23 are not limited to this example. For example, one set of three fluid supply / discharge bags 21 or one larger fluid supply / discharge bag 21 is set, and further, a plurality of sets are arranged without arranging a stabilizing plate 22 in each set. May be. In short, it is only necessary to be able to perform the planting of the start-up step 2 and the detection of the internal pressure by the horizontal and stable ascent of the upper and lower sets of the fluid supply / discharge bag 21. The number of fluid supply / discharge bags 21 and the number of combinations, and the number of stabilizer plates 22 and strips 23 are determined in consideration of the size and weight of the carrying bag, and the strength and weight of the material of the fluid supply / discharge bags 21 and stabilizer plate 22 are taken into account. be able to. Depending on the number of the fluid supply / discharge bags 21, the robustness and weight of the material, or the shape stability until the bulging is completed, the strips 23 and the stabilizing plate 22 may not be necessary.

  Next, the bathtub cylindrical body 3 will be described. On the storage container 1, the bathtub cylindrical body 3 is arranged in the inner space of the rising step portion 2, that is, the inner space of the fluid supply / discharge bag 21. The bathtub cylindrical body 3 itself cannot maintain a cylindrical shape, and is formed into a cylindrical shape as the rising step portion 2 is raised. That is, the bathtub tubular body 3 is folded without retaining the tubular shape when the rising step portion 2 is contracted as shown in FIG. 4, and the rising step portion 2 is extended as shown in FIG. 2 and FIG. 3. It becomes a cylindrical shape. Therefore, for example, the bathtub tubular body 3 is connected to the inner portion of the stabilizing plate 22 and the elastic cord 31 so as to rise in conjunction with the rising of the rising step portion 2. The connection between the tubular tubular body 3 and the stabilization plate 22 by the stretchable string 31 is two places in FIG. 3, but is not limited to this, and it is only necessary that the extension string 31 is able to stand up together.

  The bathtub cylindrical body 3 is a bathtub and can be filled with warm water. For this reason, the bathtub cylindrical body 3 is a cylindrical bag made of a watertight cloth-like material as a whole, and has a strength capable of withstanding water pressure and a load from the human body. In other words, the material is made of waterproof chemical fiber such as polyester or polyurethane, which is a fabric for umbrellas or tents, and natural fibers that are coated. It is connected. In addition, since the surroundings of the bathtub cylindrical body 3 have the start-up step part 2 and the storage container 1, the waterproofness of the bathtub cylindrical body 3 itself may be a material that oozes out.

  The bathtub cylindrical body 3 made of such a material is formed of a cylindrical body having a partially different diameter in accordance with the human body shape in a standing posture, that is, the bathtub cylindrical body 3 has an inner space shape corresponding to the human body shape. 2 and 3, for example, as shown in FIGS. 2 and 3, the bottom is thin so that the stirrer 18 can be accommodated, the upper half from the waist is thick, and the top is thickest so that the upper part can move the arm. It is made to have a diameter, and it is made to be several centimeters depending on the place so that the space between the person and the tubular body is narrowed while the person is standing in the bathtub tubular body 3. The parts with different diameters are waterproofed by bonding or sewing together by bonding or welding. And the lower end of the bathtub cylindrical body 3 is formed in the bag shape, has the drain outlet 171, and is connected to the discharge part 17 provided with the three-way solenoid valve 173. The upper end is formed so as to be constricted at the neck portion or with a sealing lid 24 so that internal heat, steam and hot air are contained and exhausted from the exhaust port 25 as necessary. In this case, since the bathtub cylindrical body 3 is made as large as one person, it can be made as a personalized product for each individual, or as a standard product suitable for adults or children. For this reason, the bathtub cylindrical body 3 itself is detachably attached to the storage container 1 and the rising step portion 2 according to the person entering the expansion string 31 if the elastic string 31 is unwound.

  Further, the bathtub tubular body 3 has circular, elliptical, or annular pipes around the tubular body at several places in the length direction of the tubular body (seven places in the examples of FIGS. 2 and 3). 32 is attached. Inside the annular pipe 32, a plurality of holes (not shown) are formed and nozzles (not shown) are attached. A hole (not shown) is formed in the cylindrical body corresponding to the nozzle, and hot water can be poured into the bathtub cylindrical body 3 through the nozzle. That is, this pipe 32 is a supply pipe for hot water or a special liquid described later, which also serves as reinforcement at a plurality of locations of the bathtub cylindrical body 3. In addition, if the cloth of a cylindrical body is stuck and reinforced according to the position of this pipe 32, a durable cylindrical body will be made. In addition, since the tip of the nozzle contacts or faces the human body, it is necessary to consider whether the tip of the nozzle is recessed from the surface of the cylindrical fabric, or an elastic material with no injury or smooth shape processing. is there. Of course, the nozzle and the cylindrical body are watertight without adhesion due to adhesion or the like. Further, as shown in the figure, the pipes 32 are communicated by a supply hose 33 wound in a spiral shape so that expansion and contraction can be easily performed, and hot water and special liquid can be supplied from all the pipes 32. In FIG. 2, an adjustable seat belt 34 is provided at a person's waist position. The belt 34 has a structure in which an end is attached to a pipe 32 connected to an elastic string 31 connected to a stabilizing plate 22, and is wound to support a thigh or is formed in an annular shape, and supports the upper body. . Therefore, the belt 34 serves as a seat for an elderly person who can get up to some extent by himself / herself, and also serves as a seat for a healthy person who can freely move.

  The stirrer 18 is arrange | positioned in the lower end part of the bathtub cylindrical body 3 in the example of FIGS. This stirrer 18 is for stirring the warm water between the human body and the bathtub tubular body 3 during bathing, for generating swirling water of warm water, and for washing the human body in a standing posture. It is. The structure of the stirrer 18 is such that a rotating drum 181 used in a washing machine is attached under the foot, and a liquid with a plurality of holes is partitioned between the foot and the rotating drum 181 to facilitate passage of liquid. By rotating the rotating drum 181, spiral water is created up to the upper stage of the bathtub tubular body 3, and the body is washed. In addition, if there is a shower using a high-pressure pump as will be described later, the stirrer 18 can be substituted, so the installation of the stirrer 18 is not indispensable.

  Now, the use of the storage container 1, the rising step 2, and the bathtub cylindrical body 3 as described above will be described. The storage container 1 carried to the required location has its lid 13 removed, and a bather stands at the center of the tubular tubular body 3 on the stirrer 18 as shown in FIG. A fluid (hereinafter referred to as air) is injected from the supply unit 14 into the lowermost stage of the fluid supply / discharge bag 21. When the bottom two fluid supply / discharge bags 21 are filled with air and a constant internal pressure is detected by an internal pressure detector (see 75 in FIG. 11), the electromagnetic valve 141 of the fluid supply / discharge bag 21 is closed to seal the air. Stop supplying. Subsequently, the solenoid valve 141 is switched and the supply of air to the next two upper fluid supply / discharge bags 21 is started. Similarly, the air is filled, and the solenoid valve is closed upon detection of a constant internal pressure, and the supply of air is stopped. In this way, the upper fluid supply / discharge bag 21 is filled with air in order, and the three sets of six fluid supply / discharge bags 21 are filled as shown in FIG. 5, and then the five sets of ten fluid supply / discharges shown in FIGS. The bag 21 is filled. And the bathtub cylindrical body 3 becomes a cylindrical shape and wraps a human body with the raise of the starting step part 2 by filling with air of this fluid supply / discharge bag 21. When the standing step 2 rises to the waist in FIG. 5, the seat belt 34 is finely adjusted according to the body shape of the bather. The description about the supply of air here is also given in FIG.

  When bathing in a state where the bathtub tubular body 3 wraps the human body, the drain outlet 171 is closed by the three-way electromagnetic valve 173, the drain outlet 172 is opened, and then the pipe is supplied from the supply section 15 via the supply hose 33. Hot water is supplied into the bathtub cylindrical body 3 from 32 nozzles. And a warm water is filled to the neck position of the bathtub cylindrical body 3, and a body can be warmed by being immersed in warm water to the neck of a human body. In addition, in order to prevent a decrease in temperature due to a decrease in the amount of hot water and to maintain a desired temperature, a method of always supplying hot water to overflow 35 and draining / circulating from the drain port 172 was provided. At this time, the body can be washed by stirring the hot water with the stirrer 18, and further, the body can be washed in accordance with the intention of the bather, although the bather is standing by a hand. Further, for example, when the bather wants to bathe only the lower body, the riser 2 is raised to the state shown in FIG. 5 and hot water is supplied to the bathtub tubular body 3 at the raised position, so that the lower body bathing is performed. it can. When taking a shower, the drain outlet 171 is opened by the three-way solenoid valve 173, the drain outlet 172 is closed by the three-way solenoid valve 173, and then hot water is supplied from the nozzle of the pipe 32 via the supply hose 33 from the supply section 15. If you squirt, you can have a shower that encourages you to wash your body. Moreover, the shower with various special liquids can be performed by connecting the supply part 15 to a special liquid water tank (refer 93 of FIG. 11) in this state.

  Although the above description has described the case where hot water is supplied from the supply hose 33 to the bathtub tubular body 3 and bathing or showering is performed, the hot air is blown out from under the feet by connecting to the supply unit 16. Air drying and heat insulation are possible, and if hot steam is blown out, it becomes a sauna bath. In this case, effectively, the upper end portion of the bathtub tubular body 3 needs to be squeezed at the neck position of the bather or covered with a sealing lid 24 so that warm air and steam do not escape. In any case, various baths are possible at the same place and posture depending on the supplied fluid. The supply and discharge of warm water, special liquid water, warm air, and steam will be described with reference to FIG.

  The bathtub tubular body 3 of the bathtub shown in FIGS. 1 to 5 uses a fabric made of chemical fiber or natural fiber formed into a tubular shape. In FIG. 6, the bathtub tubular body 3 is formed by a plurality of floating ring-shaped inner stretchable bags 36, an inner stabilizing plate 37, and a strip 23, similar to the rising step 2. This inner elastic bag 36 is provided in the inner space of the rising step 2 so as to be extendable and contractable in a cylindrical shape, similar to the bathtub cylindrical body 3 of the bathtub shown in FIGS. 1 to 5. An inner stabilizing plate 37 is placed and fixed on the inner stretchable bags 36 stacked in a plurality of stages (five stages in FIG. 6) to stand up and be planted while keeping the level. The bathtub tubular body 3 shown in FIG. 6 is fluid-tight by bonding or welding between the inner elastic bags 36 and between the inner elastic bags 36 and the inner stabilizing plate 37 so that fluid does not leak between the inside and the outside. Are stacked. Also, the inside and outside of each of the four five-stage inner stretch bags 36 shown in FIG. 6 communicate with each other, and bulges to rise upward when a fluid (for example, air) is supplied. Wilt. Note that the two inner stretchable bags 38 at the top are made large in diameter to facilitate the movement of the arms. Furthermore, the nozzle of the pipe 32 of the bathtub tubular body 3 shown in FIGS. 1 to 5 is fluid-tightly accommodated in the inner stabilizing plate 37 in the example of FIG. Supply.

It is preferable that the expansion / contraction of the inner expansion / contraction bag 36 rises in synchronization with the rising of the fluid supply / discharge bag 21 of the rising step portion 2. For this reason, the fluid supply / discharge bag 21 and the inner expansion / contraction bag 36 of the rising step portion 2 are communicated with each other at a required location. Preferably, for example, four inner elastic bags 36 smaller than the waste bag 21 are filled with fluid. The stabilizing plate 22 of the rising step portion 2 and the inner stabilizing plate 37 of the bathtub tubular body 3 are connected to each other by an elastic cord 31 so as to be interlocked with each other, and the lateral stability of the bathtub tubular body 3 is also achieved.

In FIG. 6, a fluid bag 39 is provided inside the inner elastic bag 36. The fluid bag 39 is arranged to change the shape of the inner space so that the inner space of the uniform inner elastic bag 36 matches the shape of the human body, that is, to reduce the amount of hot water used. In the inner elastic bag 36 of FIG. 6, a fluid bag 39 is provided at a small-diameter partial position of the bathtub tubular body 3 shown in FIGS. The fluid bag 39 communicates with the inner elastic bag 36 at that position and can be inflated and contracted in conjunction with the expansion and contraction of the inner elastic bag 36. Thus, the bathtub tubular body 3 shown in FIG. 6 is composed of the stacked inner elastic bag 36, the inner stabilizing plate 37, and the bottom bag portion that accommodates the stirrer 18, and between the inner stabilizing plate 37 and between the inner stabilizing plate 37 and the stirrer 18. Between the partition plates, a strip 23 similar to the strip 23 provided in the rising step 2 described above is provided. The functions of the start-up stage 2 in FIG. 6, the air supply / discharge section 14, the hot water supply section 15, the steam / hot air supply section 16, and the discharge section 17 are the same as those in FIGS. Description is omitted.

  So far, it has been explained that the bathtub is portable and can be expanded and contracted to form a bathtub shape. Aside from the bathing of healthy people, this bathtub was proposed here to reduce the burden and labor of the elderly and caregivers. Here, when bathing an elderly person, the apparatus which conveys an elderly person to a bathtub is required. In this case, since the bathtub can be carried and does not become bulky, it can be installed anywhere such as next to the bed. Therefore, if the elderly can move to the storage container of the bathtub, the elderly can easily take a bath. In other words, the device for transporting the elderly needs a simple structure.

  7 to 9 show the lifting device 4. This lifting device 4 is a movable rack 42 that is assembled in a box shape by planting four pipes having casters 41 at the lower end, and a lifting means 43 for lifting an elderly bather is provided on the ceiling portion. The lifting means 43 is provided with a lifting belt 44 for fixing and lifting the bather. Here, the moving rack 42 can freely move in the caster 41, and the lifting means 43 is, for example, a manual chain block or an electric vertical mechanism. The lifting belt 44 is a belt adapted to the body shape of the bather, and is simply indicated by a line in the figure, but supports the weight from the thigh to the buttocks and the waist and supports the weight under the arm arm. is there. Specifically, a structure in which the thighs and arms are passed through belts 441 and 442 (or belts formed in a ring shape) wound in a ring shape is preferable. Further, in some cases, a headband belt (not shown) that supports the head may be provided.

  When the bather is lifted by the lifting device 4, as shown in FIG. 9, for example, the elderly person lying down is taken off and a belt is attached to the thigh or arm, and then the elderly person is lifted by the lifting means 43. Lift the person gradually. At this time, since the movable rack 42 itself can move, the belt 441 is raised by the elevating means 43 and the movable rack 42 is moved forward while raising the upper body, so that the elderly person can be lifted easily with respect to the fixed bedding 45. Can do. After the lifting, if the moving rack 42 is moved and moved onto the installed bathtub, bathing is immediately possible. When taking a bath, the user may take a bath with the lifting belt 44 attached, or the elderly person may sit down on the stool belt 34 by removing it from the bathtub and removing the lifting belt to move and exercise. You can take a bath.

  FIG. 10 shows a simplified case of a seismic bed. The earthquake-resistant bed 5 has a structure surrounding the bed to protect elderly people sleeping on the bed from, for example, collapse of the building, and the lifting means 43 and the lifting belt described in the description of FIGS. 44 and a slide structure (not shown) that can move them back and forth, are intended to lift an elderly bather. In this case, since the bathtub has a size that can be carried as described above, it can be placed under the bedding 45 and the bed shown in FIG. . As for the lifting of the elderly, as described with reference to FIGS. 7 to 9, the belt 441 is attached to the thigh and the arm, and the lifting means 43 lifts the elderly person. After lifting, it is possible to immediately take a bath by withdrawing the bedding 45 and the bed.

  So far we have described the movement of bathtubs and the elderly. In this bathtub, since the body as a bathtub is formed by raising the raising step portion 2, a means for supplying / discharging fluid such as air to the fluid supply / discharge bag 21 and the inner elastic bag 36 of FIG. 6 is indispensable. In addition, in the case of showers, hot water is supplied and discharged, and in the case of a sauna, steam supply is naturally required. Other functions such as bathing, showering, sauna and even hot air drying, combined with being able to carry in this bathtub without having to provide a bathroom that can be showered in the building or a sauna room as in the past However, supply / discharge means such as hot water, steam, and even hot air will be provided as necessary. In this case, the main tub itself can be carried and connected to the supply / discharge section 14, the supply sections 15, 16 and the discharge section 17, so even if there is no supply / discharge means in the immediate vicinity, the hose If it is extended, supply and discharge of hot water, etc. can be done easily.

  FIG. 11 shows a system for supplying and discharging air, hot water, special liquid water, hot air, and steam supplied to and discharged from the storage container 1. This is a system diagram equipped with everything. For example, when using only a home bath, only air, hot water and drainage systems a, b and d are used, and hot air and steam system c is omitted to reduce costs. You can also In other words, the system and related devices and equipment are selected according to the purpose of the user.

  In FIG. 11, the upper part shows a plan view of the bathtub, and the lower part shows a selectable equipment or device (fluid supply / discharge device) to be connected and a connection system diagram of the device 7 for controlling the direction of the fluid. The middle stage is a hose 6 that connects the upper stage and the lower stage, and has one-touch connection ports 61 and control lines 62 at both ends. Symbols a to o displayed in duplicate indicate, for example, a connection portion using a hose, and indicate that connection portions having the same reference symbol are connected.

  In the connection system, a six-way electromagnetic valve 141 that supplies and discharges fluid (here, air) to the start-up step portion 2 and the inner elastic bag 36 is first disposed. The supply / discharge part 14 of the six-way solenoid valve 141 is connected to the supply / discharge port 71 of the three-way solenoid valve 76 via the pressure sensor 75, and the three-way solenoid valve 76 is connected to the compressor 83 and the suction machine 84. ing. That is, a, a, e, and f are connected in the connection portion.

In the supply of air, the compressor 83 is driven, and the fluid supply / discharge bag 21 at the lowermost end and the inner expansion / contraction bag from one port of the connection part a and the six-way electromagnetic valve 141 via the connection part e and the three-way electromagnetic valve 76. Air is supplied to 36. Then, when the fluid pressure in the lowermost fluid supply / discharge bag 21 and the inner expansion / contraction bag 36 rises and is detected by the pressure sensor 75, the six-way solenoid valve 141 is switched, and the second set of fluids above the next port. Air is supplied to the supply / discharge bag 21 and the inner elastic bag 36. In this way, air is gradually supplied to the rising step 2 and the inner elastic bag 36, and the rising step 2 rises. After the air is filled, the air is sealed in the fluid supply / discharge bag 21 and the inner telescopic bag 36 by switching to the neutral port of the six-way solenoid valve 141.

  In discharging the air, the suction device 84 is driven, and the fluid supply / discharge bag 21 at the uppermost end and the inner expansion / contraction bag from one port of the connection part a and the six-way electromagnetic valve 141 via the connection part f and the three-way electromagnetic valve 76. Air is discharged from 36. When the air in the uppermost fluid supply / discharge bag 21 and the inner expansion / contraction bag 36 is discharged, the six-way electromagnetic valve 141 is then switched, and the air in the second set of fluid supply / discharge bag 21 and the inner expansion / contraction bag 36 from the top. Discharged. In this way, the rising step 2 and the inner elastic bag 36 are gradually contracted from the upper end. At this time, the strips 23 between the stabilizing plates 22 can be smoothly contracted because they are pulled downward by the spring 231 and thus horizontally.

  In the above description, the compressor 83 and the suction machine 84 are used for supplying and discharging air. However, in a simpler manual supply / discharge strategy, a bicycle vacuum cleaner with a compression tank as a compressor or a household vacuum cleaner as a suction machine is used. The air can be supplied to and discharged from each pair of fluid supply / discharge bags 21 and the inner elastic bag 36. In this case, in order to fill and hold air in the fluid supply / discharge bag 21 and the inner elastic bag 36, each set of the fluid supply / discharge bag 21 and the inner elastic bag 36 is provided with a stopper that is closed by internal pressure. A structure that can be opened manually is also possible. Such a simple measure is effective as a bathtub for disaster prevention or outdoor where the carrying amount is restricted.

  Further, the connection system in FIG. 11 is provided with a supply unit 15 for warm water or special liquid water. The supply unit 15 is connected to a three-way electromagnetic valve 77 having a supply port 72 via a high-pressure pump 81 having a variable pressure. The three-way electromagnetic valve 77 is connected to a dedicated small hot water tank 91 and the dedicated small hot water tank. It connects with the conventional bathtub 92 utilized when not using 91, and connects with the special liquid water tank 93 on the other hand. That is, as for a connection part, b, g or m, and i are connected. Therefore, when bathing or taking a hot water shower, hot water is supplied into the bathtub cylindrical body 3 from the dedicated small hot water tank 91 or the conventional bathtub 92 via the three-way solenoid valve 77, the high pressure pump 81 and the supply unit 15, When taking a special liquid shower, the special liquid shower water is supplied to the tubular tubular body 3 through the three-way electromagnetic valve 77, the high-pressure pump 81 and the supply unit 15 switched from the special liquid water tank 93. The high-pressure pump 81 adjusts the strength and supply amount (speed) of the shower, and a cleaning power and a massage effect can also be expected by this adjustment. In addition, the dedicated small hot water tank 91 is about 70 liters, assuming that the amount of hot water collected in the bathtub tubular body 3 is about 5 cm from the surface of the body, for example, 170 cm and 68 kg. May be a tank of about 90 liters. When hot water is stored, the amount of hot water is greatly reduced as compared to a general bath (70 cm, 90 cm, 50 cm bath) which has about 315 liters. Next, since the special liquid water tank 93 uses a shower exclusively, it becomes a small tank of about 5 liters as the amount of circulation and heat insulation. And as a special solution, it can be a medical facility if you develop a solution that works against skin diseases such as washing water (soap water) that removes dirt, bath water that is good for health and beauty, carbonated water, hot spring water, ionic water, etc. . This can be used not only for nursing care but also for health, beauty and medical equipment.

  Furthermore, in the connection system of FIG. 11, a supply unit 16 for steam and hot air is provided. The supply unit 16 is connected to a three-way electromagnetic valve 78 having a supply port 73, and the three-way electromagnetic valve 78 is connected to the steam generator 86 on the one hand and to the hot air generator 87 on the other hand. That is, as for a connection part, c, k, and l are connected. Therefore, steam is supplied from the steam generator 86 into the bathtub tubular body 3 via the three-way solenoid valve 78 and the supply unit 16 to form a sauna bath, and the three-way solenoid valve 78 switched from the hot air generator 87. And hot air is supplied to the bathtub cylindrical body 3 via the supply part 16. In this case, as the hot air generator 87, a commercially available futon dryer or a dryer can be used.

  Next, drainage of warm water and special liquid is performed in the discharge part 17 in the connection system of FIG. The discharge unit 17 is connected to a four-way electromagnetic valve 79 having a discharge port 74 via a high-pressure pump 82, and the first outlet of the four-way electromagnetic valve 79 is connected to a dedicated small hot water tank 91 or a conventional bathtub 92. The second outlet is connected to the special liquid water tank 93, and the third outlet is connected to the drainage point 94. The connection portions d, h or n, j, and o are connected. For this reason, dirty water that cannot be used thereafter is discarded from the drainage point 94, and the usable drainage is returned to the dedicated small hot water tank 91, the conventional bathtub 92, or returned to the special liquid water tank 93. Especially when circulating hot water or special liquid, this return drainage route is used. In addition, when returning warm water, you may make it remove dirt by interposing the filter 80 in a drainage route. The high-pressure pump 82 here is provided for draining to a position higher than the bathtub, draining hot water quickly, and draining shower water at the same speed as the supply.

  The example of FIG. 11 illustrates hot water, special liquid water, steam, and warm air. For this reason, piping and electromagnetic valves with hoses were provided. However, according to the use of the bather, the equipment is further simplified in the case of using only to immerse in warm water so as to warm the body, or to use only a shower or a sauna requiring steam. In addition, as the drive control of each solenoid valve, independent operation control for each solenoid valve by remote control and automatic operation by a program according to the user's application, for example, gradually taking into account the physical condition of the elderly by warm air or steam Various combinations such as keeping the body warm, shower washing with soapy water, washing with hot water shower, pooling hot water, taking a bath, drying with hot air, etc. can be automatically performed by program setting. Although the compressor 83 and the suction machine 84 are indispensable, other equipment and devices that can be selected for connection may require special equipment or devices depending on the function. It is possible to select inexpensive products or use existing equipment. In FIG. 11, a generator 95 is illustrated as a power source during a disaster or outdoors. In the case of automatic operation by the above program, automatic switching is necessary, and the three-way solenoid valves 76, 77, 78, and the four-way solenoid valve 79 in the device 7 for controlling the direction of fluid are directional switching valves using electromagnetic force. However, in some cases, a three-way switching valve or a four-way switching valve that can be switched by driving or manually operating air, a machine, a push button, or the like can be provided.

  The bath shown in FIGS. 1 to 6 is based on the premise that the bather takes a bath in a standing position, and the bathing of an elderly person who can be lifted as shown in FIGS. 7 to 10 has been described. However, as shown in FIGS. 7 to 9, some elderly people cannot lift, cannot stand, and some people like a sitting posture. Therefore, a bathtub with a sitting (sitting) posture by a chair is illustrated in FIG. This will be described with reference to FIG. 12 to 18, the same reference numerals are given to portions that perform the same functions as those in FIGS. 1 to 6, and descriptions thereof are omitted.

  12-18, the bathtub of the sitting posture based on the bathtub shown in FIGS. 1-3 is shown. Although the size and shape are slightly different, the standing step 2 having the same function as FIGS. 1 to 3, the bathtub tubular body 3, the storage container 1, the bath chair 10 for a sitting posture, and the folding chair The child 103 is constituted by an exclusion plate 26 that changes the shape of the space in front of the chest. In this case, since the bather in the sitting posture is located in the inner space of the bathtub tubular body 3, the bulk viewed from the plane of the bathtub tubular body 3 is larger than that of FIG. . Due to this sitting posture, the bath chair 10 is arranged in the inner space of the bathtub tubular body 3. The bath chair 10 is extended by injecting air into two communicating elastic bags 101 so that a person can sit down, and the space under the armpit is reduced in a sitting posture. On the bath chair 10, a detachable seat chair 103 with a shower nozzle built in the buttocks and the backrest is placed. In addition, this bathtub cylindrical body 3 and the bath chair 10 are also made according to a bather's body shape, and are provided so that attachment or detachment is possible for the reduction of hot water.

  A single-opening exclusion plate 26 is attached on the uppermost stabilizing plate 22 of the rising step portion 2. The exclusion plate 26 is raised so that the bath chair 10 is raised and the riser 2 is planted in a state where the bather is seated on the seat chair 103 and then a lid is put on the front of the bather. Next, the fluid bag 262 attached to the exclusion plate 26 is inflated to reduce the shape of the internal space in front of the chest of the bather. The flat plate 261 interposed between the fluid bags 262 has a nozzle for ejecting a shower. In addition, as in FIG. 6, a fluid bag 39 is arranged to reduce the space around the bather's legs. The presence of the fluid bag 39 and the fluid bag 262 reduces the unnecessary space in the start-up step 2 to change the shape of the internal space, reduces the amount of hot water used during bathing, and increases the safety of the bather during bathing. It is to secure. Accordingly, as shown in FIG. 5, the hot water is connected to each pipe 32 and the uppermost stabilizing plate 22 by the supply hose 33 from the supply unit 15 and is supplied from each pipe, and also via the uppermost stabilizing plate 22 and the exclusion plate 26. Then, the flat plate 261 is supplied in a shower shape. Furthermore, the hot water is supplied in a shower form from the buttocks and backrest of the seat chair 103 via the flat plate 102 under the elastic bag 101 of the bath chair 10, the supply hose 104, and the bath chair 10 as another route. 12 to 14, an air supply / exhaust unit 14, a hot water supply unit 15, a steam / hot air supply unit 16, and a discharge unit 17 are provided to maintain a sealed state for a sauna bath or heat insulation. Accordingly, a sealing sheet 24 is provided at the upper end. An exhaust port 25 for discharging steam is also provided.

  The case where an elderly person bathes in such a bathtub illustrated in FIGS. 12-15 is described. First, from the state of the storage container 1 shown in FIG. 15, the exclusion plate 26 on the rising step 2 is raised 90 degrees, and air is injected into the two stretchable bags 101 communicating as shown in FIG. The bath chair 10 is started up. And after raising the backrest part of the seat chair 103, it makes it sit on the seat chair 103, supporting an elderly person. Next, the rising step 2 is planted, and the fluid bag 262 is inflated after the exclusion plate 26 is tilted and fixed. Subsequent bathing and showers are the same as described above, and will be omitted.

  In FIGS. 17 and 18, when the elderly person who cannot stand is bathed, the elderly person is placed on the seat chair 103 that can be bathed. In order to reduce the burden on the elderly, as shown in FIG. 17, the elderly who sleeps on the bedding is placed on a seat chair 103 which is a flat plate opened at 180 degrees, and is transferred to the seat chair 103. As shown in FIGS. 17 and 18, the back of the chair 103 is raised, the elderly person is lifted together with the sitting chair 103 by the moving rack 42, and is transferred to the bath chair 10 together with the sitting chair. When the lifting device 4 is used, the sitting chair 103 is removed from the bath chair 10 and used. Subsequent bathing and showers are the same as described above, and will be omitted. In addition, if a hole is made in the buttocks of the seat chair 103 so that it can be placed in a Western-style toilet, care can be taken to take a bath after excretion.

  Although the conventional system can be used as an outdoor in the event of a disaster, it is a structure that requires a lifting frame such as a lifting device, but in the example shown in FIG. 19, it is smaller, lighter, and less expensive than the above. Describe the method. Although the size and shape are different instead of the start-up step 2 as shown in FIGS. 1 to 3, the outer tubular body 27 using the same structure and material as the bathtub tube 3 is used as the start-up step. When the tubular body 3 is connected by the elastic cord 31 and the outer tubular body 27 is lifted by the lifting handles 46 and 47, the bathtub tubular body 3 is also lifted. Then, after lifting up to the waist with a lifting string 48 connected to the lifting handle 46, the lifting handle 49 is wound up to the neck with a lifting string 49 connected to the lifting handle 47. Others are the same as described above, and will be omitted.
