Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention has been improved so that even a cared person who is unable to move on their own can at least turn over, take a bath, or use the toilet automatically. Concerning personal care systems for bedridden patients, etc.

[Conventional technology and its problems] For bedridden patients who are unable to move on their own, the position on which the patient's weight is placed remains the same, even with dedicated care at home and thorough hospital treatment. , prone to bedsores. In addition, it usually takes a great deal of manual labor to use the toilet or take a bath. In addition, having a long-term companion not only costs money, but also puts a psychological burden on the sick person.
The whole family ends up living a depressed and unpleasant life.

Therefore, it is ideal for bedridden patients who can automatically turn over and turn over in bed to prevent bed sores without any human assistance, and can complete personal care such as toileting and bathing with as little human assistance as possible. It is hoped that a nursing care system will emerge. This situation has an urgent importance that cannot be overlooked, considering the global trend towards an aging society.

[Purpose of the Invention] This invention was made in consideration of the above circumstances, and its purpose is to enable a person to turn over automatically at all times without the need for an attendant, and to spread the weight evenly so that a person can lie on his side for a long time. We have created a personal care system for sick people that has the effect of preventing bedsores and allowing people to take care of themselves, such as using the toilet or bathing, without having to ask for help as much as possible. It is about providing.

[Means for Solving the Problems] The present invention includes a bed provided in a substantially horizontal state at a predetermined distance from an installation surface, and a bed divided into at least three parts along the height direction. The formed first, second, and third bed plate portions are provided at respective connecting portions of these adjacent bed plate portions, and at the connection portions, the first and second bed plate portions or the second and third bed plate portions are connected to each other. a pivot member for supporting the plate portions so as to be displaced alternately between a normal position in a horizontal state and a use position in which the bed plate portions are bent downward into a trough shape; a driving member that is driven to be displaced between the bed plate portion, a top-opening bathtub that is connected to the bed plate portion and has a toilet bowl inside; A conveying device that conveys the user to the upper surface of the bathtub, a conveying plate section placed in a closed state at the upper end opening of the bathtub, and a conveying plate section that is connected to three locations, namely, a first to third conveying plate section. and a hinge mechanism that allows bending and displacement with respect to each other at each of these connecting portions, and the first conveying plate portion are rotatable between a horizontal conveying position and a substantially vertical use position. ,
As the first conveyance plate section is displaced from the conveyance position to the use position, the second conveyance plate section is rotated by the hinge mechanism so as to form a substantially L-shape with respect to the first conveyance plate section. The second conveyor plate has an opening formed in correspondence with the opening of the toilet, and is normally closed and placed in the opening of the toilet. Sometimes, as the first conveyance plate section is displaced to the use position, a lid member is opened to communicate with the opening of the toilet bowl, and the first conveyance plate section is connected between the conveyance position and the use position. As the lid member is displaced, the operating rod slightly rotates the lid member in the vertical direction and also rotates it in a substantially horizontal plane, thereby displacing the lid member between an open position and a closed position with respect to the opening. It consists of a drive mechanism that makes it possible.

[Operation and Effects of the Invention] According to the present invention configured as described above, the bed plate portions of the beds adjacent to each other are alternately displaced between the normal position and the use position by the drive member, so that the bed plate portions of the beds adjacent to each other are alternately displaced between the normal position and the use position. The patient's weight is alternately placed on different parts of the body, and the patient is able to turn over independently without being attended to.
When taking a bath, the user is automatically transferred from the bed plate section to the transfer plate section, where the first transfer plate section is pivoted from the horizontal transfer position to the vertical use position, and the second transfer plate section is rotated from the horizontal transfer position to the vertical use position. Since the second conveyor plate is placed over the opening of the toilet bowl, the user automatically sits on the second conveyor plate without any difficulty, and is automatically placed in the bathtub without the assistance of another person. It can be soaked in.
Also, when you have the urge to defecate, the lid member is opened and sits on the second transport plate, so
The buttocks are exposed to the toilet bowl through the opening, allowing the user to empty the toilet by himself. Furthermore, after finishing bathing or using the toilet, the first conveying plate part rotates upward together with the second and third conveying plate parts, and rotates back from the use position to the original horizontal sleeping position, In this state, it is sent back to the bed plate section.

As a result, the patient can take a bath and use the toilet by himself without relying on human help, which not only prevents bedsores but also reduces the burden on the family and the psychological burden on the patient. Moreover, when using the toilet, the opening is opened and closed by rotating the lid member vertically and horizontally, but the opening and closing mechanism for this lid member is simply a ring-shaped circular cam that is rotatable around an eccentric shaft. This has excellent effects such as simplifying the structure, saving space, and ensuring cost advantages.

If the apron 267 is rotated downward as shown by the two-dot chain line in FIG. 9, the caregiver can be in close proximity to the user U. makes it easier to assist users.

Next, the operation of the above configuration will be explained starting from the bed plate section.

First, as shown in FIG. 1, the mattress 66 and the comforter 67 are set on the first to third bed plate parts 7, 8, and 9 via the belt 76, and the user U, such as a sick person, places his or her head on the mattress. The patient is placed on the main pillow 68 and placed on his/her back so as to be positioned on the second bed board section 8. In this state, as shown in FIGS. 1 and 2, the first, second and third bed plate sections 7, 8, 9
are in their normal positions horizontal to each other.

At this time, if the user wishes to turn over, the hydraulic cylinder 30 is driven to move the rod 30a in the direction of arrow A1 shown in FIG. 2. Then, roller 3
1 runs along the rail 32 in the longitudinal direction to its fullest extent and then stops. Along with this, the moving rod 33 rotates its lower end in the direction of arrow B1 around the roller 31, and
Move in one direction. The upper end of the moving rod 33 rotates in the direction of the arrow C1 about the pin 34 and rotates in the direction of the arrow D1.
The fork-shaped moving rod 33 receives the rod 30a, becomes integral with the rod 30a, and is positioned flush with the rod 30a. During the process in which the upper end of the moving rod 33 moves downward, the second and third bed plate parts 8 and 9 are rotatable with respect to each other by the hinge mechanism 11. It comes to rotate in the direction of arrow E1 about the hinge mechanism 10, and the third bed plate part 9 comes to be rotationally displaced in the direction of arrow F1 by the rod 15. As a result, the second and third bed plate parts 8 and 9 are bent downward at approximately 90 degrees at the hinge mechanism 11 and are displaced to the use position, as shown in FIG. A valley-like depression is formed inside the third bed plate portions 8 and 9. Along with this displacement, the convex portion 64 separates from the stopper 62, while the support rod 35 rotates in the direction of arrow G1 around the pin 37 and becomes substantially in line with the moving rod 33, so that the rod 15 moves around the arm 13. It rotates in the direction of arrow H1 and is displaced from a vertical state to an inclined state.

At this time, the second bed plate part 8 changes from a horizontal position to an inclined state, so that the user U shifts from a supine position to a recumbent state in which his weight is applied to the third bed plate part 9.

As the bed plate section is displaced from the horizontal position to the use position, the upright piece 54 is displaced from the vertical position to the inclined position, but since the link 57 rotates in the direction of arrow I1, the stay 52 is moved to the receiving position. 53 in the same direction, and is displaced parallel to the third bed plate portion 9. As a result, while the user U rests the back of his head on the main pillow 68, the side of his head is well supported by the side pillow 39. Further, when the hydraulic cylinder 30 is driven to move the rod 30a backward in the direction opposite to the arrow A1, the roller 31 moves in the same direction and the moving rod 33
rotates in the opposite direction to arrow B1, and the rod 30a
Move away and stand up to your original position. As a result, the upper end of the moving rod 33 moves upward, so that the second bed plate 8 rotates in the opposite direction to the arrow E1, and the third bed plate 9 rotates in the opposite direction to the arrow F1. It rotates and returns from the tilted use position to its original horizontal normal position. Along with this, the link 57 in the side pillow 39 rotates in the opposite direction to the arrow I1, the receiving part 53 returns to the original horizontal state together with the stay 52, and the temporal region of the user U is separated from the side pillow 39. The weighted state is released and the back of the head returns to its original state supported on the main pillow 68.

Furthermore, when the hydraulic cylinder 20 is driven, the moving rod 24 moves together with the roller 23 in the direction shown by arrow J1 in FIG. Accordingly, the fork-shaped moving rod 24 rotates about the pin 25 in the direction of arrow K1 in FIG. 2, receives the rod 20a, and overlaps the rod 20a integrally. As a result, as the portion where the pin 25 is located moves downward, the support rod 26 rotates about the pin 28 in the direction of arrow L1 and is positioned substantially in line with the movable rod 24. Then, since the part where the pin 25 is located falls, the bed plate part 7 first rotates in the direction of arrow M1 via the rod 14, and the second bed plate part 8 rotates in the direction of arrow M1 about the hinge mechanism 11. The first and second bed plate parts 7 and 8 rotate in the N1 direction and the hinge mechanism 1
It bends downward at a substantially right angle with the 0 part as a boundary, and is displaced to the use position.

Accordingly, the user U shifts from a supine position on the second bed board 8 to a sideways position on the third bed board 9. At the same time, as shown in FIG. 4, the side plate 84 rotates in the direction of arrow K about the pivot mechanism 86 and is displaced from a substantially vertical position to an inclined position, but the action of the universal joints 93 and 94 is also With the help of this, the pulley 92 is also tilted together with the side plate 84, so that the pulley 92 can be maintained in a well-wound state without removing the wire 82.

Furthermore, as the bed board portion moves from the normal position to the use position, the upright piece 46 of the side pillow 38 becomes inclined, so the link 49 rotates about the pin 51 in the direction of the arrow O1. Then, the stay 40 moves together with the receiving part 41 from the horizontal position to an inclined position parallel to the first bed plate part 7.
As a result, when the user U moves from the supine position to the horizontal position, the side head of the user U is supported by the receiving part 41 of the side pillow 38 while the back of the head of the user U rests on the main pillow 68.

Further, when returning the first and second bed plate parts 7 and 8 from the use position to the normal position, when the hydraulic cylinder 20 is driven, the rod 20a moves in the opposite direction to the arrow J1, and the moving rod 24 moves in the opposite direction to the arrow J1. It rotates in the opposite direction to the arrow K1 and stands up from the lying position. As the upper end of the moving rod 24 moves upward, the first and second bed plate parts 7 and 8 rotate through the pins 25 in the directions opposite to the arrows M1 and N1, respectively, forming a V-shape. Returns from the concave use position to the original horizontal normal position.

Accordingly, the support rod 26 rotates in the opposite direction to the direction of the arrow L1 and returns from the position in line with the moving rod 24 to the original inclined position. At this time, the user U changes from a sideways position on the first bed board 7 to a supine position on the second bed board 8 .

In addition, in the case of the side pillow 38, the upright piece 46 returns from the inclined state to the original vertical state, the link 49 rotates in the opposite direction to the arrow O1, and the stay 40, together with the receiving part 41, moves to the first bed. It returns to the original horizontal state from the tilted position parallel to the plate part 7. Therefore, the side of the head of the user U moves away from the receiving part 41 of the side pillow 38, and the back of the head rests on the main pillow 68, returning to its original state.

According to the above configuration, the second and third bed plate parts, together with the first and second bed plate parts 7 and 8, are displaced between the horizontal normal position and the valley-shaped use position. Since it is provided so that the user U who is lying on his/her back can automatically change to the sideways state alternately from side to side. As a result, even if user U is bedridden and unable to move on his or her own,
This is extremely convenient as it allows the patient to turn over in bed without having to rely on the help of a caregiver or other attendant. This eliminates the need for your body weight to always rest on one spot, and it is better distributed, allowing you to stay on your side for longer periods of time, which has the advantageous effect of eliminating the problem of pressure sores.
There is no need to worry about the cost of nursing care over a long period of time, and the patient is able to maintain a peaceful state of rest without feeling the psychological pressure of having to be accompanied by someone. In addition, as the bed board moves from the normal position to the use position, it will slump to the left and right when turning over, so the mattress 66 will follow the bed board well and prevent the bed from shifting laterally. Not only that, but also
A good sleeping condition can be obtained for the user U without creating a gap with the futon on the back side and the chest side.
Furthermore, as the user U moves from a supine position to a sideways position, he or she can freely meet visitors on either side, which is convenient for viewing posters and television images.

It is also effective when the dorsal side is examined during hospital rounds.

Furthermore, when the second and third bed plate parts 8 and 9 are displaced from the normal position to the use position, the side pillow 39
moves to a tilted state, the side head of the user U is well supported by the side pillow 39, and there is no unnecessary lateral displacement of the futon 66, making it convenient to turn over in bed. Moreover, in order to realize this, the elongated hole 57
It is only necessary to use the links 57 and 49 having the links 57 and 49a, which contributes to a reduction in cost and to a simplification of the structure.

In addition, the same thing can be said when the first and second bed plate parts 7 and 8 are displaced from the normal position to the use position, providing convenience when turning over.

Next, when the above-described turning motion on the bed plate section is completed, the first transfer plate section 20 of the bathtub 200
1, the rollers 201a and 201b rotate in a predetermined direction, and the belt 201c moves in the direction of the arrow o in FIG. Next, regarding the bed section,
The comforter 67 has been removed, and in this state the second
The illustrated motor 97 is energized, and the driven pulley 96 rotates in a predetermined direction. Then, the pulley 92 rotates via the drive shaft 95 and the universal joints 94 and 93 in this order, the wire 82 is pulled, and the roller 80 moves along the rail 78 in the direction of arrow m in FIG. 3.
At the same time, the roller 75 rotates in the direction of arrow n in FIG. 3, and the belt 76 moves in synchronization with the roller 80. In addition to moving the belt 76, the mattress 6
6 is pulled through the string 83, the user U moves along with the mattress 66 in the direction of the arrow m, and the user U passes through the gap Gp from the leg to the first
is transferred to the belt 201c of the conveyance plate section 201,
It is placed in the position shown in FIG. On the other hand, mattress 6
6 is connected to the string 83, the mattress 66 passes through the gap Gp and is displaced downward along the rail 78, passing through the guide roller Ra on the way, as shown by the two-dot chain line in FIG. It is stored in the inner bottom of the bed. In this state, the rollers 201a, 20
The rotation of the belt 1b stops, and the movement of the belt 201c stops, resulting in a stationary state. At the same time, the motor 97 is de-energized, the driven pulley 96 stops rotating, and the pulley 92 stops, so the wire stops moving and the mattress 66 is held in the storage position.

As shown in FIG. 7, in the case of the conveyance plate section to which the user U is sent, the first to third conveyance plate sections 201, 202, 203 are in sleeping positions in a horizontal state, and the user U is positioned supine on these conveyor plates.

When the user U wants to relieve himself, he drives the hydraulic cylinder 213 in the state shown in FIG. Then, the rod 214 of the hydraulic cylinder 213
a extends in the direction of arrow L. Since the pressure contact state of the lid member 206 against the opening 205 is released at the very beginning of this process, the rod 214a and the hydraulic cylinder 213 are rotated downward about the pin 214b due to their own weight, and the opening 205 is opened. , moves from the position shown by the two-dot chain line to the position shown by the solid line in FIG. At this time, the circular cam 215 rotates the bolt 217 while rotating the roller 218 due to the weight of the rod 214a, as shown in FIG.
It is rotated in the direction of arrow E about , and stops at that position. Accordingly, the operating rod 207 rotates downward together with the roller 211 in the direction opposite to the arrow A to place the roller 211 on the rail 212.

Furthermore, the rod 214a of the hydraulic cylinder 213
rotates in the direction of arrow C and extends in the direction of arrow L from the position shown by the solid line to the position shown by the two-dot chain line in FIG. It is rotated in the direction of arrow B about . For this reason, the lid member 20
6 moves approximately horizontally from the solid line position to bathtub 2.
00 and is located below the apron 200a as shown by the two-dot chain line.

In this state, the hydraulic cylinder 237 is driven and the rod 237a extends in the direction of arrow M as shown by the solid line in FIG.
It is rotationally displaced in the direction of arrow N about 6.
Therefore, the link 233 moves downward as shown by the arrow O, and the link 232 is rotationally displaced around the pin 230 in the direction of the arrow P. As a result, the opening/closing lid 22
8 rotates in the direction of arrow Q from the horizontal two-dot chain line position and moves to the approximately vertical position shown by the solid line, and the toilet bowl 22
Open the opening at 7.

In this state, the hydraulic cylinder 220 in FIG. 8 is driven to extend the rod 220a in the direction indicated by arrow R and displace it to the position indicated by the two-dot chain line. Due to this extension, the arm 219a receives a rotational force in the clockwise direction via the pin 221.
01 is rotationally displaced in the direction of arrow S from the horizontal solid line position to a substantially vertical position about pin 218a. Accordingly, the link 223 rotates in the direction of arrow T about pin 224, and the link 225 rotates in the direction of arrow V about pin 226. As a result, the second conveyance plate section 202 rotates upward around the pin 218a and moves toward the arrow W by the hinge mechanism a.
The toilet bowl 227 rotates in the direction to form an L-shape as a whole and moves onto the open toilet bowl 227 as shown by the chain double-dashed line and assumes the use position, and the opening 205 communicates with the upper end opening of the toilet bowl 227. . As the link 268a moves in the direction of the arrow Y, the third conveying plate section 203
rotates in the direction of arrow Z around the hinge mechanism b, and is displaced perpendicularly to the side surface of the toilet bowl 227, as shown by the two-dot chain line. In the process in which the conveying plate is displaced from the sleeping position to the use position, the user U descends into the bathtub 200 as the conveying plate moves, and the roller group 204 automatically moves the user's buttocks to the right as shown in the figure. opening 2 of the conveying plate section 202.
Located at 05. When the user finishes using the toilet in this state, hot water is sprayed upward from the discharge port 253b of the spray pipe 253 for a predetermined period of time to wash the buttocks of the user U. Then, the hot air generator 250 is activated, and warm air is blown out from the tip through the pipe 252 to dry the buttocks.

After using the toilet, the rod 220a is driven by the hydraulic cylinder 220 to move in the direction opposite to the arrow R from the extended position, and rotate the arm 219a in the direction opposite to the arrow S to the position shown by the broken line. .

As a result of this rotational displacement, the first conveyance plate section 201 is rotationally displaced about the pin 218a in the direction opposite to the arrow S, and returns from the position shown by the two-dot chain line to the original position shown by the solid line. Along with this, the link 223 rotates in the direction opposite to the arrow T around the pin 224 and moves from the position indicated by the two-dot chain line to the original position indicated by the solid line, and the link 225 rotates in the direction opposite to the arrow V around the pin 226. is rotated in the opposite direction to the position indicated by the solid line.
Therefore, the second conveyance plate part 202 is rotated by the hinge mechanism b in the direction opposite to the arrow W, and returns to the original parallel state flush with the first conveyance plate part 201. At the same time, the link 268a begins to move in the opposite direction to the arrow Y, so that the third conveying plate portion 203
is rotationally displaced in the direction opposite to the arrow Z by the hinge mechanism b, and the first and second conveying plate parts 2 are returned to the original position.
It returns to a parallel position flush with 01 and 202. Along with this movement, the user U also moves upward from inside the bathtub 200 and returns to the original position facing up on the transport plate section.

Thereafter, the hydraulic cylinder 237 is driven and the rod 237a is displaced in the direction opposite to the arrow M. Therefore, the circular ring 234 rotates about the pin 236 in the direction opposite to the arrow N, and the link 2
33 in the opposite direction of arrow O. As a result of these operations, the link 232 rotates in the direction opposite to the arrow P, and the opening/closing lid 228 is rotationally displaced in the direction opposite to the arrow Q around the pin 230, so that the toilet bowl 227
Close the top opening.

Around this time, the hydraulic cylinder 213 is driven, and the rod 214a moves in the direction opposite to the arrow L, moving from the position indicated by the two-dot chain line to the position indicated by the solid line. Therefore, the roller 211 moves on the rail 212, the hydraulic cylinder 213 itself performs a rotational displacement in the direction opposite to the arrow C, and the operating rod 207 along with the lid member 206 moves in the opposite direction to the arrow B around the vertical pin 209. As shown in FIG.
Apply a lateral force as shown in Wh. This causes the circular cam 215 to move around the bolt 217 as shown by the arrow D.
In order to rotate in the direction, the operating rod 207 moves obliquely upward from the position shown by the solid line and shifts to the position shown by the two-dot chain line. As a result, the hydraulic cylinder 213, together with the rod 214a, rotates upward in the direction of arrow A about the horizontal pin 210, as shown in FIG. Therefore, the lid member 206 moves upward to close the opening 205 of the second conveyance plate section 202. At this time, the displacement of the rod 214a in the backward direction is
Since the amount is set to be slightly larger than the required minimum amount, a pressure contact force is generated in the direction from the lid member 206 to the opening 205, which causes the hydraulic cylinder 2
13 is held together with rod 214a in the closed position shown in solid lines in FIG.

If you wish to take a bath in the bathtub 200 instead of using the toilet, you can close the top opening of the toilet bowl 227 with the opening/closing lid 228 and then open the bathtub 200.
A predetermined amount of hot water is supplied into the tank from the sprue 269. Then, as shown in FIG. 7, the lid member 206
With the opening 205 left open, the first to third transport plate parts 201, 202, 203 are bent and moved from the sleeping position to the use position in the same manner as when using the toilet.

Accordingly, the user U moves downward according to the conveyance plate part 200 without clothes, enters the bathtub 200, and soaks in the hot water in the bathtub 200 while sitting on the second conveyance plate part 202. become. in this case,
If user U can move his arm on his own,
A shower 270 shown in FIG. 9 may also be used. After washing your body, use your feet etc. to press the operating member 2.
61 in the direction of arrow K, the stopper 259 is pulled up through the stud 260, and the outlet 258 is opened to discharge the hot water in the bathtub 200 to the outside. After that,
The hot air generator 250 supplies hot air from the pipe 252 to the user U's leaky body in the same manner as when urinating, and a drying effect is performed.

When drying after bathing is completed, the hydraulic cylinder 22
0, the transport plate returns from the L-shaped use position where it is folded into steps to the sleeping position where it is parallel to each other and flush with each other, in the same way as when the user finished using the toilet. The person U is placed in an initial supine position on the conveyor plate.

Next, in this state, the rollers 201a and 201b
rotates, and the belt 201c moves in the opposite direction to the arrow o in FIG. At the same time, the belt 76 is moved by the roller 75 on the bed board in the direction opposite to the arrow m, and the motor 97 on the bed board is energized, the driven pulley 96 rotates in the opposite direction to the direction during conveyance, and the wire rail 78 through 82
The inner roller 80 is moved in the direction opposite to the arrow m. As a result, the mattress 66 is pulled by the strings 83 and moved upward from the storage position.

At this time, the user U is sent in the opposite direction to the arrow o by the belt 201c, and when he reaches the position of the gap Gp, his head encounters the main pillow 68 of the futon 66 and is placed on it, and in this state, the user U is moved in the direction opposite to the arrow o. moves further in the opposite direction. Therefore, the user U is placed on the mattress 66 in the order of the back, buttocks, and legs.
It is transported back to the bed plate section and returns to its original normal position as shown by the two-dot chain line in FIG. In this state, the rotation of the rollers 201a and 201b is stopped and the belt 2
01c stops moving and becomes stationary. At the same time, the motor 97 is de-energized, the driven pulley 96 stops rotating, and the pulley 92 stops, so the wire stops moving and the mattress 66 stops.
is now placed on the bed board as before.
Thereafter, the user U puts on his clothes, and in this state the comforter 67 is placed over the user U by a caregiver or the like.

After being conveyed from the bed plate part to the bathtub 200 in this way, the conveyance plate part is rotated from the sleeping position to the use position according to the time of defecation or bathing, and the user U is
The user can enter and exit the bathtub 200 while sitting on the transfer plate 202, and even a person who is unable to move his/her own body can bathe and defecate automatically without the need for human intervention. can be added. As a result, even if user U is a bedridden patient who has difficulty moving, he or she will be able to take care of his/her own personal needs such as bathing and defecating whenever he wishes, so he will not have to worry about his family or others. , they don't feel psychological pressure, and even if they have family members, they don't have to worry about taking care of them, so they can live a rational life without feeling depressed or unpleasant.

In addition, in the above embodiment, the cover member 206 is always urged to rotate in the direction indicated by the arrow X in FIG. 9, particularly in the above embodiment. 206 is the operating rod 2
Since it is always in contact with 07,
Since the lid member 206 is rotatably displaced within a substantially horizontal plane, even if the upper end opening of the bathtub 200 is narrow, the lid member 206 can be rotatably displaced and passed through without any hindrance, which is extremely convenient.

Furthermore, in order to open the lid member 206, it is first necessary to slightly displace the lid member 206 downward, and then to rotate it in the horizontal direction. cam 2
15 vertically and movable up and down using an eccentric shaft, it is possible to maintain a simple structure, unlike a configuration that uses a large-scale device using a worm wheel mechanism or a link mechanism. Moreover, it is advantageous in terms of cost, and is not bulky and can contribute to space saving.

Furthermore, especially in the above embodiment, as the first conveyance plate section 201 rotates in the direction of the arrow S and the use position is displaced, the hot air generator 250 moves downward by its own weight via the link 251. Therefore, the pipe 252 is prevented from being subjected to an unreasonable tensile force at the connecting portion between the first and second conveyor plate portions 201 and 202, and there is no risk of damage. Moreover, this implementation does not require any complicated structure, is space-saving, and is advantageous in terms of cost.

In the above embodiment, the bed plate section is divided into three sections, but it is not limited to this number, and may be divided into four sections.

In addition, in the side pillows 38 and 39, as the bed plate portion is displaced from the normal position to the use position, the side pillow 3
When 8,39 changes from a horizontal state to an inclined state,
A toggle mechanism may be used instead of the links 57, 49.

Further, when the bed board parts move from the normal position to the use position, the angle formed is not limited to a right angle as in this embodiment, but can be changed as appropriate depending on the situation.

Further, in the above embodiment, the turnbuckle mechanism 29, t was used to telescopically adjust the length of the support rods 26, 35, but it is of course not limited to this mechanism; for example, a rack and pinion mechanism may be used. Alternatively, the racks may be fixed to the support rods 26, 35, and the racks may be moved in the axial direction by the rotation of the pinion, so that the support rods 26, 35 can be displaced in the expansion/contraction direction. In this case, instead of manual operation, the pinion may be rotated by a motor to move the rack in an axially extending and contracting manner.

In addition, a hinge mechanism is provided at the center of each bed plate so that each bed plate bends slightly inward when the bed plate moves from the normal position to the use position. It's okay.

In addition, in the process of moving the bed plate section from the normal position to the use position, in the above embodiment, the moving rod 33 is rotated until it integrally overlaps the rod 30a of the hydraulic cylinder 30, but the rotation is You may make it stop suitably on the way. In this case, the rotational angular displacement of the moving rod 33 may be configured to be performed in a plurality of stages, such as two or three stages. Alternatively, the configuration may be such that the user U can selectively set an appropriate stage among the plurality of stages.

Although the bathtub 200 of the above embodiment is used for toileting and bathing, the use is not limited to this, and the bathtub 200 can be used for eating, reading, or painting while the user is in the position of using the hot water while it is being discharged. , it can also be applied when watching on a portable television.

Further, in the above embodiment, the common hot air generator 250 is used for toileting and bathing, but a blower having a strong air blowing ability may be used for drying after bathing. Alternatively, a hot air generator that can adjust the wind force to weak or strong levels may be used.

A convex portion may be provided around the roller 201a of the first conveying plate portion, a hole may be made in the belt 201c to eliminate slippage, and an idle roller may be provided on one side of the belt barrel between the rollers 201a and 201b instead of a stop. Furthermore, the rollers 75, 75 of the bed plate parts 7, 8, 9 may also be provided with convex portions in the same manner, and holes may be made in the belt 76 to eliminate slips.

Alternatively, the first conveying plate section may be formed hollow, and a large number of through holes may be provided in the outer wall, so that hot air is blown out from the through holes to the user's body during drying after bathing. In this way, since warm air is supplied from a wide area, it is convenient to dry the body in a short time, and it is particularly suitable for the cold winter season due to its heat retention effect.

Furthermore, the second and third conveyance plate sections 202,
Although 203 is made up of a long roller, it may be made up of a short roller or a large number of beads with wires passing through them. Further, the roller in this case may be formed into a hollow cylindrical shape to have a thinner wall, thereby reducing the weight.

In addition, rotational displacement of the conveying plate section, movement of the lid member 206, injection pipe 253 or hot air generator 25
0, a remote control panel Pa as shown in FIG. 13 may be provided so that the user U can move it as desired by operating this panel. In addition, the conveyance plate section includes first to third conveyance plate sections 201, 202, 2
It is not limited to the three sections of 03, but may be divided into a plurality of sections, such as four sections.

In addition, the first conveying plate section 201 has a belt 201c.
Instead, it may be constructed from an ordinary flat plate.

In addition, even if the user U on the bed board part is slightly shifted to the left and right sides due to sleeping position etc., the user U can be moved to the toilet 222 by adjusting the bed board part left and right.
It can be transported reliably. Furthermore, the scope of application may include not only sick people but also healthy people depending on the situation.

In addition, various changes may be made in the specific implementation without departing from the gist of the invention.
