Next, in FIG. 6, the first bed plate section 201
A hot air generator 250 is disposed on the back surface of the device via a pair of links 251. This link 25
Both ends of the first
As the bed plate part 201 rotates from the horizontal position to the vertical position, the hot air generator 250 is displaced downward from the position shown by the two-dot chain line to the position shown by the solid line, and the hot air supply pipe 252 is moved downward. This pipe 252 is connected to the first and second bed plate parts 201 and 202.
This prevents unnecessary tensile force from being applied to the hinge mechanism a between the two. As shown in FIG. 6, when the bed board is in the use position where the bed board is bent into a V-shaped lightning bolt shape as a whole, the tip of this pipe 252 is connected to the opening of the second bed board 202. 205, facing upward. Also, in FIG. 6, 253 is a jet pipe of a washing device, which has the function of spouting out hot water for washing after using the toilet, and is provided so as to be movable in a substantially horizontal direction, and one end of which is connected to a spool of thread. shaped pivot 253a

Reference numeral 254 denotes a vertical lever, which is pivotally supported approximately in the center by a pin 255 so as to be rotatable in a vertical plane, and whose lower end is formed in the shape of a forked fork. The lower end of this fork shape is connected to sandwich the pivot 253a of the injection pipe 253, and the upper end is rotatably supported by a pin 256 to one end of the horizontal lever 257. This horizontal lever 257 is capable of reciprocating in the horizontal direction, as shown by double-headed arrows F and G in FIG. Then, when the horizontal lever 257 is moved in the direction of the arrow F, the vertical lever 254 is rotationally displaced from the position indicated by the two-dot chain line to the position indicated by the solid line in the direction of the arrow H about the pin 255, and the injection is performed via the pivot portion 253a. Move the pipe 253 in the direction of arrow J. Furthermore, when the horizontal lever 257 is moved in the direction of the arrow G, this moving force is transmitted to the vertical lever 254 via the pin 256, and the vertical lever 254 rotates from the solid line position around the pin 255 in the direction opposite to the arrow H. Move to occupy the position indicated by the two-dot chain line. As a result, the injection pipe 253 moves in the opposite direction to the arrow J via the pivot portion 253a. Such an injection pipe 253
The position of the discharge port 253b can be set as desired by adjusting the movement of the discharge port 253b. Reference numeral 258 denotes a discharge port formed at the bottom of the bathtub 200;
is formed in a tapered shape that gradually widens toward the upper surface, and a plug 259 having a tapered circumferential surface is removably attached to this tapered surface. At the center of the upper surface of this stopper 259 is a stud 260.
is provided in a protruding manner, and one end of a dogleg-shaped operating member 261 is rotatably supported by a pin 262 . The operating member 261 is rotatably supported at the center by a pin 262, and the end opposite to the pin 262 is in elastic contact with a leaf spring 264 that curves upwardly. It matches. After bathing, the operating member 261 is connected to the pin 262.
When the operating member 26 is rotated in the direction of arrow K about
1 slides on the upper surface of the leaf spring 264 with elastic deformation, pulls up the stopper 259 and opens the outlet 258, and the hot water in the bathtub 200 flows through the outlet 25.
Water is drained to the outside from 8. Further, when the operating member 261 is rotated in the direction opposite to the arrow K, the leaf spring 264
The plug 259 is moved downward while being elastically deformed so that the tapered surfaces are brought together and the discharge port 258 is closed by the plug 259 as before. Note that 265 shown in FIG. 3 is a water storage tank for a toilet bowl, and a pipe 266 is provided from this water storage tank 265 to the toilet bowl 227. Reference numeral 267 designates a flat rectangular apron rotatably provided on the side surface of the bed board using a pin 268a, and a pair of rollers 30 are attached to this apron.
0, 301 and a belt 302 stretched around these rollers 300, 301, and can be displaced between a horizontal position shown by a solid line and a vertical position shown by a two-dot chain line.
If the apron 267 is rotated downward as shown by the two-dot chain line in FIG. 3, the caregiver can be in close proximity to the user U. It makes it easy to provide assistance.

Next, the operation of the above configuration will be explained.

First, as shown in FIG. 1, when the user U is in a sleeping state, the first to third bed plate parts 201, 20
2 and 203 are in horizontal positions with respect to each other, and the user U is positioned on his back on these bed plate parts.

When the user U wants to relieve himself, he drives the hydraulic cylinder 213 in the state shown in FIG.
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, as shown in FIG. 4, the circular cam 215 rotates in the direction of arrow E around the bolt 217 while rotating the roller 219 due to the weight of the lid member 206, 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.

Further, as 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. 1, the roller 211 moves on the rail 212. At the same time, the operating rod 207 is rotated in the direction of arrow B around the vertical pin 209. For this reason, the lid member 206
moves in a substantially horizontal direction from the position indicated by the solid line, opens the opening 205 in the second bed plate section 202, climbs over the upper end opening Op of the bathtub 200, and is located below the apron 200a as shown by the two-dot chain line. .
In this manner, when using the toilet, the opening 205 in the second bed plate 202 is opened in advance by the lid member 206 when the first to third bed plate parts 201, 202, 203 are in the horizontal sleeping position. . Then, as will be described later, when the user returns from the use position to the original sleeping position after using the toilet, the lid member 206 closes the opening 205 by following an operation opposite to that described above. As far as the opening and closing of the opening 205 in the second bed plate section 202 by the lid member 206 is concerned, it functions similarly during bathing, which will be described later.

In this state, the hydraulic cylinder 237 is driven and the rod 237a is moved as indicated by the arrow M as shown by the solid line in FIG.
The circular link 234 is rotated in the direction of the arrow N about the pin 236. Therefore, the link 233 moves downward as shown by the arrow O, and the link 232 is moved around the pin 230 by the arrow P.
rotationally displaced in the direction. As a result, the opening/closing lid 228 rotates in the direction of the arrow Q from the horizontal position indicated by the two-dot chain line and moves to the substantially vertical position indicated by the solid line, thereby opening the upper end opening Up of the toilet bowl 227.

In this state, the hydraulic cylinder 220 in FIG. 2 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 bed plate part 202 rotates in the direction of arrow W by the hinge mechanism a, forming a V-shape on the way, and then forming an L-shape as a whole, above the open toilet bowl 227 as shown by the two-dot chain line. The toilet bowl 2 is moved to the use position, and the opening 205 of the second bed plate part 202 is in an open state.
It communicates with the upper end opening Up of 27. As the link 268 moves in the direction of the arrow Y, the third bed plate part 203 rotates in the direction of the arrow Z around the hinge mechanism b.
It is displaced vertically to the front side of 7. In the process in which the bed plate section is displaced from the sleeping position to the use position, the user U moves the bed plate section toward the bathtub 20.
falls within 0. In this process, the bed plate forms a V-shape, so the user U's buttocks automatically fit into the V-shaped recess without shifting to the left or right, and the back side is placed in the first bed. While contacting the plate part 201, the buttocks are located on the second bed plate part 202, and in this state are securely located in the opening 205 of the bed plate part 202, and the toilet bowl 22 is inserted through the opening 205.
This corresponds to the state of communication with the upper end opening Up of No.7. 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 via the pipe 252 to dry the buttocks.

After using the toilet, the hydraulic cylinder 22 is used to return the bed board from the use position to the original sleeping position.
0, the rod 220a moves in the direction opposite to the arrow R from the extended position, and the arm 219a
is rotated in the direction opposite to the arrow S to the position shown by the broken line.

With this rotational displacement, the first bed plate portion 201 is rotated 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 bed 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 bed plate part 201. At the same time, the link 268 begins to move in the direction opposite to the arrow Y, so the third bed plate part 203 is rotationally displaced in the direction opposite to the arrow Z by the hinge mechanism b, and the first and Second bed plate part 20
1, 202 and returns to the parallel position. 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 bed board.

After that, the hydraulic cylinder 237 is driven and the rod 237a is displaced in the direction opposite to the arrow M. Therefore, the circular link 234 rotates about the pin 236 in the direction opposite to the arrow N, and the link 234 rotates in the opposite direction to the arrow N.
33 in the opposite direction of arrow O. As a result, the link 232 rotates in the opposite direction to the arrow P, and the opening/closing lid 228 is rotationally displaced in the opposite direction to the arrow Q around the pin 230, as shown by the two-dot chain line in FIG. Close the upper end opening Up of the toilet bowl 227.

Before and after this operation, the hydraulic cylinder 213 is driven, and the rod 214a is moved and displaced 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. 4, it encounters the circular cam 215 and collides with the roller 218, applying a lateral (horizontal) force as shown by the white arrow Wh. This causes the circular cam 215 to
The operating rod 2 rotates in the direction of arrow D around 17.
07 moves diagonally 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, moves along the arrow A with the pin 214b as the center, as seen in FIG.
Rotate upward in the direction. Therefore, the lid member 206 moves upward to open the opening 205 of the second bed plate section 202.
will be closed. At this time, since the displacement of the rod 214a in the backward direction is set to be slightly larger than the minimum required amount, a pressing force is generated from the lid member 206 toward the opening 205, and this causes the hydraulic cylinder 213 to move toward the 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 from the sprue 269 into the room, and the second bed plate section 202 is deformed and moved so as to be bent from the sleeping position to the use position with the opening 205 in the second bed board section 202 being opened by the lid member 206 in the same manner as when taking a toilet. let

Accordingly, the user U moves downward according to the bed board part, enters the bathtub 200, and moves to the second bed board part 202, which is placed on the opening/closing lid 228 of the toilet bowl 227, which is in the closed state. Bathtub 20 while sitting
You will be able to soak in hot water within 0. In this case, if the user U can move his/her arms by himself/herself, a shower 270 shown in FIG. 3 can be used. After washing your body, use your foot or the like to rotate the operating member 261 in the direction of arrow K, pull up the stopper 259 through the stud 260, open the discharge port 258, and close the bathtub 2.
Drain the hot water inside 00 to the outside. After that, the pipe 2 is heated by the warm air generator 250 in the same way as when using the toilet.
Warm air is supplied from 52 so as to blow onto the wet body of the user U from below, thereby performing a drying action.

When drying after bathing is completed, the hydraulic cylinder 22
0, the bed plate parts return from the use position where they are folded into a step shape, which can be called an L shape, to the original sleeping position where they are parallel to each other and flush with each other, in the same way as when they finished using the toilet. The person U is placed in the initial supine position on the bed board, and the lid member 206 is rotated by the operation rod 207 in the opposite direction to the arrow B in FIG. 2 bed plate part 2
02 opening 205 is closed.

In this way, according to the above configuration, the bed plate portion is rotated from the sleeping position to the use position depending on the time of toileting or bathing, and the user U can sit in the bathtub 200 while sitting on the second bed plate portion 202. Even people who cannot move their bodies by themselves can automatically take a bath and relieve themselves with almost no human intervention. As a result, even if user U is a bedridden patient who cannot move, he or she will be able to take care of his/her 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 spend all their time caring for them, so they can live a rational life without feeling depressed or unpleasant.

In addition, since the lid member 206 is always urged to rotate in the direction indicated by the arrow X in FIG. 3 by the pin 208 located at an eccentric position,
Since the lid member 206 is always in contact with the operating rod 207, the lid member 206 is rotationally displaced within a substantially horizontal plane, so that even if the upper end opening Op of the bathtub 200 is narrow, It is extremely convenient because the cover member 206 can be rotated and passed through without any hindrance.

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 21
5 is arranged vertically and is movable up and down using an eccentric shaft, it is possible to maintain a simple structure, unlike a configuration using 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, in the above embodiment, as the first bed plate section 201 rotates in the direction of the arrow S and is displaced to the use position, the hot air generator 250 is moved 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 connection portion between the first and second bed 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 application is applied when using the toilet or taking a bath, but the application is not limited to these, but can also be applied when eating, reading, or watching a portable television.

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

Alternatively, the first bed plate section may be formed hollow, and a large number of through holes may be provided in the outer wall so that warm 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, which is particularly suitable for the cold winter season.

Furthermore, the second and third bed plate portions 202,
Although 203 is constructed from a long roller, it may be constructed from 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 reduce its weight.

In addition, a remote control panel is provided to adjust the rotational displacement of the bed board, the movement of the cover member 206, and the movement of the injection pipe 253, and the user U can move as desired by operating this panel. It may be configured as follows. In addition, the bed plate part is the first
The present invention is not limited to the three sections of the third bed plate sections 201, 202, and 203, but may be divided into a plurality of sections, such as four sections.

In addition, the first, second and third bed plate portions 20
1, 202, and 203 may be constructed from ordinary flat plates instead of the belt 201c or rollers.
