Next, in FIG. 6, a hot air generator 250 is arranged on the back surface of the first bed board section 201 via a pair of links 251. As shown in FIG. Both ends of this link 251 are rotatably supported, and as the first bed plate portion 201 rotates from the water top position to the vertical position, the hot air generator 251
is displaced downward from the position shown by the two-dot chain line to the position shown by the solid line, sending a pipe 252 for supplying hot air downward, and this pipe 252 connects to the hinge between the first and second bed plate parts 201 and 202. This prevents unnecessary force from being applied to the mechanism a in the tensile direction. As shown in FIG. 6, when the bed board is in the use position where the bed board is bent into a lightning bolt shape as a whole, the tip of this pipe 252 is connected to the opening 205 of the second bed board 202. It is facing upward through the. Further, in FIG. 6, 253 is the injection pipe 1 of the washing device, which has the function of ejecting hot water for washing after using the toilet, and is provided so as to be movable in a substantially horizontal direction. It has a thread-shaped pivot portion 253a and is located outside the bathtub 200, with the other end protruding into the interior of the toilet bowl 227. 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 its lower end is formed in the shape of a forked fork. The lower end of this fork-like shape is connected to sandwich the pivot 253a of the injection pipe 253, and the upper end is pivotally supported by a pin 256 to one end of a horizontal lever 257. This horizontal lever 25
7 is capable of reciprocating in the horizontal direction, as shown by double-headed arrows F and G in FIG. And horizontal lever 25
7 in the direction of the arrow F, the vertical lever 254 is rotationally displaced from the position of two points vm in the direction of the arrow {circle around (2)} 4 to the position of the solid line; Move 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 bin 256, and the vertical lever 254 moves from the position of the solid line to the arrow I with the bin 255 as the center.
It rotates in the opposite direction to 4 and occupies 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. The movement of the injection pipe 253 is adjusted by the displacement, and the discharge port 253 b
You can set the position as desired. Reference numeral 258 denotes a discharge port formed at the bottom of the bathtub 200, and this discharge port 258 is formed in a tapered shape that gradually becomes wider toward the sixth surface, and a plug having a tapered peripheral surface is provided on this tapered surface. 259
A stud 260 is protruded from the center of the upper surface of this plug 259, and one end of a dogleg-shaped operating member 261 is rotatably supported by a pin 262. has been done. The operating member 261 is rotatably supported by a pin 262 at the center, and the end opposite to the pin 262 is in elastic contact with a leaf spring 264 that curves in a convex manner. engaged with the state. After bathing, when the operating member 261 is rotated in the direction of the arrow around the bottle 262, the operating member 261 slides while causing elastic deformation on the two surfaces of the leaf spring 264.
The stopper 259 is pulled upward to open the outlet 258, and the hot water in the bathtub 200 is drained to the outside from the outlet 258.

Furthermore, when the operating member 261 is rotated in the direction opposite to the arrow, the plate spring 264 is elastically deformed while the stopper 259 is moved downward to align the tapered surfaces of the discharge port 258.
is opened and closed again by the stopper 259.

In addition, the number 265 shown in FIG. 3 is a water storage tank for the toilet bowl, and a pipe 266 is provided from the water storage tank 265 to the toilet bowl 227.

267 is a flat, rectangular nib or ron that is rotatably provided on the side of the bed board by means of a pin 268a. 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, I will explain the effect of the ``Uki'' structure.

First, as shown in FIG. 1, when the user U is sleeping, the first to third bed plate parts 201, 202, and 203 are in horizontal positions with respect to each other, and the user U is The patient is placed in a supine position.

However, when user U wants to relieve himself, the first
The hydraulic cylinder 213 is driven in the state shown in the figure. Then, the rod 214a of the hydraulic cylinder 213 extends in the direction of the arrow. At the very beginning of this process, the opening 2 of the lid member 206
05 is released, the rod 214
a and the hydraulic cylinder 213 and the bottle 214 due to its own weight.
It is pivoted downward about b, opens the opening 205, and 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 is rotated in the direction of arrow E around the bolt 217 while rotating the roller 218 due to the weight of the rod 214a shown in FIG. Stop at.

Along with this, the operating rod 207 moves along with the roller 211 toward the arrow A.
The roller 211 is rotated downward in the opposite direction to the rail 21.
2 Place it on top.

Furthermore, the rod 214a of the hydraulic cylinder 213 is
As the roller 21 rotates in the direction of the arrow and extends in the direction of the arrow from the position shown by the solid line to the position shown by the two-dot chain line in FIG.
1 moves along the rail 212''-, the operating rod 207 is rotated in the direction of arrow B about the vertical bin 209. Therefore, the lid member 206 moves in a substantially horizontal direction from the position indicated by the solid line, climbs over the upper opening of the bathtub 200, 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 23
7a extends in the direction of arrow M as shown by the solid line in FIG.
The circular link 234 is rotated in the direction of arrow N about the bin 236. Therefore, the link 233 moves downward as indicated by the arrow 0, and the link 232 is rotationally displaced around the bin 230 in the direction of the arrow P. This allows the opening/closing lid 2
28 is rotated in the direction of the arrow Q from the horizontal two-dot chain line position and moved to the substantially vertical position l shown by the solid line, thereby opening the opening of the toilet bowl 227.

Further, in this state, the hydraulic cylinder 220 in FIG. 2 is driven to extend the rod 220a in the direction indicated by the 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 bin 221, so the first bed plate part 201 rotates in the direction of arrow S from the horizontal solid line position to a substantially vertical position with the bin 218a as the center. Displace. Accordingly, the link 223 rotates in the direction of arrow T about the bin 224, and the link 225 rotates in the direction of arrow V about the bin 226. As a result, the second bed plate portion 202 is connected to the hinge mechanism a.
Toilet bowl 227 rotates in the direction of arrow W, forming an L-shape as a whole through a 7-shape on the way, and is in an open state as shown by the two-dot chain line.
the opening 205 is placed in the toilet bowl 2.
27" communicates with the end opening.

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, and moves toward the front side of the toilet bowl 227 as shown by the two-dot chain line. Displaced to vertical state.

Along with this, the step portion 203S rotates upward as shown by the arrow Sa in FIG. 2, and occupies a substantially horizontal position as shown by the two-dot chain line in the same drawing. In this way, in the process of the bed board being displaced from the sleeping position to the use position, the user U descends into the bathtub 200 as the bed board moves. In this process, the bed plate forms a figure 7 shape, so the user U's buttocks automatically fit into the figure 7-shaped recess without shifting to the left or right, and the back side is placed in the first bed. While abutting the plate part 201, the buttocks are located on the second bed plate part 202, and in this state are reliably located in the opening 205 of the bed plate part 202. When you finish your urination 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 hot air is blown out from the tip via the via 252 to dry the buttocks.

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

Due to this rotational displacement, the first bed plate portion 201 moves toward the bin 218.
It is rotated about a in the direction opposite to the arrow S, and rotated back 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 is centered on the bin 224 and the arrow T
The link 225 rotates in the opposite direction to the arrow (2) and moves from the position indicated by the two-dot chain line to the original position indicated by the solid line. Therefore, the second bed plate portion 202 is rotated by the hinge mechanism 1] in the direction opposite to the arrow W, and returns to the original parallel state flush with the first bed plate portion 201.

At the same time, the link 268 begins to move in the opposite direction to the arrow Y, so the third bed plate part 203 is rotated in the opposite direction to the arrow Z by the hinge mechanism, and the first and It returns to a position parallel to and flush with the second bed plate portions 201 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 bed board.

After that, the hydraulic cylinder 237 is driven and the rod 23
7a is moved and displaced in the direction opposite to arrow M. Therefore, the circular link 234 rotates about the bin 236 in the direction opposite to the arrow N, causing the link 233 to move in the direction opposite to the arrow O. As a result, the link 232 rotates in the opposite direction to the arrow P, and the opening/closing lid 228 rotates in the opposite direction to the arrow Q around the bottle 230 to close the opening at one end 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 [,, and moves from the position indicated by the two-dot chain line to the position indicated by the solid line. Therefore, the roller 211 moves along the rail 2120, and the hydraulic cylinder 2
13 itself is rotated in the direction opposite to the arrow C, and the damage rod 207 is rotated together with the lid member 206 about the vertical bottle 209 in the opposite direction to the arrow B, and as shown in FIG. It encounters the cam 215 and collides with the roller 218, applying a lateral (horizontal) force as shown by the white arrow. As a result, the circular cam 215 rotates about the bolt 217 in the direction indicated by the arrow, so that the working rod 207 moves obliquely upward from the position shown by the solid line to the position shown by the two-dot chain line. This causes the hydraulic cylinder 213 to move together with the rod 214a.
As seen in FIG.
Rotate upward in the direction. Therefore, the lid member 206 moves upward to close the opening 205 of the second bed plate section 202.

At this time, since the displacement of the rod 214a in the backward direction is set to be slightly more than the minimum required amount,
Pressure force is generated from the lid member 206 in the direction toward the opening 205, and this causes the hydraulic cylinder 213 to press against the rod 214a.
and is held in the closed position shown in solid line in FIG.

In addition, if you want to take a bath in the bathtub 200 instead of using the toilet, you can open and close the lid 228 of the toilet bowl 227 and the end opening Up.
After closing the water spout 26 in the bathtub 200,
From 9, a predetermined amount of hot water is supplied, and the device is bent and moved from the sleeping position to the use position in the same way as when using the toilet.

Accordingly, the user U moves downward according to the bed plate part and enters the bathtub 200, and is immersed in the hot water in the bathtub 200 while sitting on the second bed plate part 202. In this case, if the user U is able to move his arm with his own blade, he can also use the shower 270 shown in FIG. 3. After washing your body, use your foot or the like to rotate the operating member 261 in the direction of the arrow and pull the stopper 259 through the stud 260.
- The hot water in the bathtub 200 is discharged to the outside by opening the drain outlet 258. Thereafter, hot air is supplied from the vibrator 252 to the wet body of the user U by the hot air generator 250, as in the case of using the toilet, and a drying effect is performed.

When drying after bathing is completed, the bed plate parts are moved back from their original positions parallel to each other and facing each other in the same manner as when the user finished using the toilet, from the L-shaped or stepwise folded position. Returning to the sleeping position, the user U is placed in the initial supine position on the bed board.

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 enter and exit the bathtub 200 while sitting on the second bed plate 202, and even those who are unable to move their bodies by themselves can bathe and use the bath automatically without the need for human intervention. You can add stool. 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 no longer have to worry about his family or others, and will be able to take care of his own personal needs such as bathing and defecating whenever he wishes. They don't feel pressured by others, and even if they have a family member, they don't have to spend all their time caring for them, so they can spend their days in a rational manner without having to deal with unpleasant feelings.

Furthermore, since the lid member 206 is always biased to rotate in the direction indicated by the arrow X in FIG. Since the lid member 206 is always in contact with the water, the lid member 206 can be rotated within a substantially horizontal plane, and even if the upper end opening of the bathtub 200 is narrow, the lid member 206 can be moved without any problem. It is extremely convenient because it can be rotated and passed through.

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. Since the cam 215 only needs to be vertically arranged and movable up and down using an eccentric shaft, a simple structure can be maintained, unlike a configuration that uses a large-scale device using a worm wheel mechanism or 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, in particular, the first bed plate portion 201
As the hot air generator af250 is rotated in the direction of arrow S and displaced from its use position, the warm air generator af250 is moved downward by its own weight via the link 251, so that the first and second bed plate parts 201. The pipe 252 is prevented from being subjected to excessive tensile force at the connection portion with the pipe 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 embodiments, 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 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, or A hot air generator that can adjust the wind power 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 possible to dry the body in just a few hours, which is particularly suitable for the cold winter season.

Furthermore, although the second and third bed plate parts 202 and 203 are constructed from long rollers, they may be constructed from short rollers or a large number of beads with wires passing through them. Furthermore, 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 portion includes the first to third bed plate portions 201.20.
2.203 is not limited to the three sections, but may be configured to be divided into a plurality of sections such as four sections.

In addition, the first, second and third bed plate portions 201, 202
．． 203 may be constructed from a normal flat plate instead of the belt 201C or rollers.

In addition, the first, second and third bed plate portions 201, 202
．． 203 and apron 200a, 267 is belt 2
Instead of 01C or low arms, it may be constructed from ordinary springs, nets, and flat plates.

In addition, in the above embodiment, a hydraulic cylinder consisting of a cylinder and a rod was used, but instead of this, a nut-shaped female thread and a rod-shaped male thread are used, and the rotation of the male thread causes the cylinder to move axially relative to the female thread. It may be configured to move.

Furthermore, the scope of application is not limited to sick people, but may also be used by healthy people depending on the situation. Also,
Self-aligning bearings may be used instead of the pins 214b, 214.

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