The weight 43 is lifted up in the direction K while being guided by the guide rods 44, and the
0 performs the displacement according to the downward displacement of the daily supply table 28.
Therefore, as described above, it is convenient for the user U to take a meal or a makeup tool from the dining table provided on the daily necessities supply table 28 while wearing the comforter 40. In particular, since the comforter 40 can be left attached, it is convenient as a measure against cold weather in winter when the temperature is low.

When the meal and the use of the makeup tool have been completed from the set, the daily supply table 28 is moved through the futon 40 through the arm 30 in the same manner as shown in FIG. It rises from the position indicated by the solid line in contact with the knee to the position indicated by the two-dot chain line, and returns to the original state. Accordingly, the pressing force of the daily goods supply stand 28 against the comforter 40 is released.
And the rotating disk 32 is rotated counterclockwise. Thereby, the semicircular spring wires 38 are pulled in the directions opposite to the arrow L in FIG. 6, and the comforter 40 is displaced in accordance with the upward displacement of the daily supply stand 28, and is placed on the apron plate 39 of the bathtub 200. To be raised.

After the futon 40 is lifted up onto the apron plate 39 of the bathtub 200 by the weight 43, the hydraulic cylinder 220 is driven by the operation of the hydraulic cylinder 220 and the arrow R is moved from the position where the rod 220a extends by the same operation as that performed after the stool. Moves in the opposite direction, and turns the arm 219a in the direction opposite to the arrow S to the position shown by the broken line (FIGS. 1 and 2). Along with this rotational displacement, the first bed board portion 201 is rotationally displaced around the pin 218a in the direction opposite to the arrow S, and returns to the original position shown by the solid line from the position shown by the two-dot chain line. Accordingly, the link 223 rotates about the pin 224 in the direction opposite to the arrow T and moves from the position indicated by the two-dot chain line to the original position indicated by the solid line, and the link 225a moves about the pin 226 to the position indicated by the solid line. Rotating displacement up to. For this reason the second

At the same time, the link 268 moves in the direction opposite to the arrow Y, so that the third bed plate portion 203 is rotationally displaced in the direction opposite to the arrow Z by the hinge mechanism b, and the first and the second bed plates 203 return to their original positions. 2nd bed board part 20
The bed returns to the sleeping position in a state parallel to and flush with 1, 202. With this operation, the user U also moves upward from the inside of the bathtub 200 and is positioned in the supine state as before.

The same effect can be obtained even with such a modified example. In this modification, the spring wire 38 is omitted and the wire 42 is
2 may be directly connected to the side edge of the comforter 40.

FIGS. 7 to 9 show another embodiment of the embodiment shown in FIGS. In this embodiment, the same members as those in FIGS. 1 and 2 are denoted by the same reference numerals, and only different portions will be described. In this embodiment, separation mattresses 51 to 53 are used.
Are placed on the first and third bed portions 201 to 203, respectively. The floating board 54 is placed on the first bed board part 201 via the mattress 51. The floating plate 54 moves up and down with respect to the first bed board portion 201, lifts the upper body portion of the user U, and moves the buttocks to the second position.
This makes it easy to change clothes by separating from the bed part 202, and has the same function as the floating plate 10 described above. On both sides of the floating plate 54, the apron plate 3 is
The thick ear portions 55 overlapping with each other are integrally formed. A relatively deep bottomed hole 56 is formed in the lower surface of the ear 55.
Is formed. Reference numeral 57 denotes a floating plate driving mechanism for vertically moving the floating plate 54. In the floating plate driving mechanism 57, 58 is a column fixed to an installation surface, and is vertically attached to an ear 55 of the floating plate 54. The arms 60 are arranged in a corresponding state, extend in the lateral direction, and have two female threads 59 formed thereon. 61 is a vertical bar, the upper end of which is inserted into a bottomed hole portion 56 formed in the ear portion 55 of the floating plate 54 by passing the apron plate 39, and the lower end portion forms a male screw portion 62; Male thread 62
Are screwed into the female screw portion 59 of the arm portion 60 so as to be able to advance and retreat. A bevel gear 63 is fitted to a portion of the vertical bar 61 located between the two arms 60. 6
Reference numeral 4 denotes a wheel driven by a motor 65, to which a bevel blade gear 66 meshing with the bevel blade gear 63 is fixed.

When the motor 65 is driven, the bevel blade gear 66 rotates via the wheel 64, and the rotational force is transmitted to the bevel blade gear 63 to rotate the longitudinal axis 61 in the forward direction. At this time, the vertical rod 61 is raised in the direction of the arrow M shown in FIG. 8 by the screwing of the female screw part 59 of the arm part 60 and the male screw part 62 of the vertical rod 61. With the vertical displacement of the vertical bar 61, the vertical bar 6
Since the upper end of the upper part 1 pushes up the inner bottom part of the deep bottomed hole portion 56 and the vertical bar 61 is fitted relatively deeply into the bottomed hole portion 56, the floating plate 54 is moved from the position shown by the solid line in FIG. It rises almost horizontally to the position shown by the two-dot chain line.
With this displacement, the upper body of the user U is moved to the first bed plate portion 2.
01, and the buttocks rise to the second bed board portion 20
Leave 2 At this time, since the user U is in a state of being lifted in the air, it is relatively easy to change the clothes of the user U, and it is possible to reduce the burden of the nurse and attendant labor. At this time, since the upper body of the user U is forcibly lifted, a secondary effect that a massage effect is obtained by exercise of the body occurs. In addition, this floating plate 5
The rising height of 4 can be set as desired or can be adjusted stepwise or steplessly in the course of the lifting.

When the user U has finished changing clothes, the motor 65 is energized again, and the bevel blade gear 66 rotates in the opposite direction to the above through the hole 64, and the rotational force is applied to the bevel blade gear 63. Transmitted to rotate the longitudinal axis 61 in the opposite direction. At this time, due to the screwing of the female screw portion 59 of the arm portion 60 and the male screw portion 62 of the vertical bar 61, the vertical bar 61 descends in the direction opposite to the arrow M shown in FIG. With the downward displacement of the vertical bar 61, the upper end of the vertical bar 61 supports the floating plate 54, so that the floating plate 54 is lowered from the position shown by the two-dot chain line in FIG. 8 to the original position shown by the solid line. With this lowering, the upper body of the user U moves through the mattress 51 to the first bed board portion 2.
01, and the buttocks are placed in the second bedboard portion 2 as before.
Touch 02. Positioning pieces 67 are formed on the left and right sides of the tip of the floating plate 54, respectively.
In the downward displacement, the positioning piece 67 is moved to the first bed plate portion 2.
01 is formed so as to be engaged with the projection 68. Further, the floating plate 54 may be made of plastic, or may be a porous plate having a large number of through holes formed on the surface for weight reduction and air permeability. In addition, this floating plate 5
4, an electric heater wire may be buried inside, and the power may be supplied in winter to warm the upper body of the user U. Also,
It goes without saying that the geometric shape of the floating plate 54 can be variously formed as required. In addition, this floating plate 54
Is detachable from the vertical bar 61, is always removed from the first bed board portion 201, is stored, and is attached as needed. When necessary, as shown in FIG. 4, the first and third bed boards 20 are provided.
Since the upper body of the user U is substantially vertical when the use positions 1 to 203 occupy the chair-shaped use positions, the floating plate 54 is placed on the mattress 51 of the first bed board portion 201 and the back of the user U. Between the entire length along the length,
When the positioning piece 67 is engaged with the protruding portion 68, the bottomed hole portion 56 formed in the ear portion 55 is automatically made to correspond to the insertion hole (not shown) formed in the apron plate 39. To place.

With the floating plate 54 inserted between the mattress 51 of the first bed board portion 201 and the back of the user U, the first and third bed board portions 201 to 201 are placed.
The operation of bringing the 203 into the sleeping position shown in FIG. 8 is performed in the same manner as described above. That is, the drive of the hydraulic cylinder 220 causes the rod 220a to move from the extended position in the direction opposite to the arrow R, and to displace the arm 219a in the direction opposite to the arrow S to the position shown by the broken line (FIGS. 1 and 2). reference). With this rotation displacement, the first bed board part 201
Rotates around the pin 218a in the direction opposite to the arrow S, and returns to the original position shown by the solid line from the position shown by the two-dot chain line. Accordingly, the link 223 rotates about the pin 224 in the direction opposite to the arrow T to move from the position indicated by the two-dot chain line to the original position indicated by the solid line.
Rotationally displaces around 26 to the position indicated by the solid line. For this reason, the second bed board part 202 is rotated in the direction opposite to the arrow W by the hinge mechanism b, and the first bed board part 201 is returned to its original state.
And return to a parallel state. At the same time, the link 268 moves in the direction opposite to the arrow Y, so that the third bed plate portion 203 is rotationally displaced in the direction opposite to the arrow Z by the hinge mechanism b, and the first bed member 203 returns to its original state. And it returns to the sleeping position in a state of being in parallel with the second bed board portions 201 and 202 and in a parallel state. Along with this operation, the user U also moves upward from the inside of the bathtub 200, and is positioned on the bed board portion via the mattress and the floating plate 54 in a supine position.

It should be noted that when the bathtub 200 was not supplied with hot water and was empty, the bathtub 200 was used for stool and personal arrangement. However, the present invention is not limited to this. It can also be applied when performing entertainment.

Although a hot air generator was used for stool and bathing, a powerful hot air generator with high power consumption may be used for drying after bathing to enhance drying performance. . Alternatively, an adjustable hot air generator may be applied to obtain a required air flow rate.

The first bed portions 201, 202, 2
03 may be hollowed to provide a large number of through-holes on the outer wall so that hot air is blown out of the through-hole to the body of the user U during drying after bathing. In this way, warm air is supplied to the body from a large area, so that the convenience of shortening the drying time can be obtained, and it is particularly advantageous in winter when the temperature is low.

Further, the second and third bed boards 20
2, 203 is composed of a long roller, but it may be composed of a large number of rosaries in which a wire is passed through a short roller. In this case, the roller may be formed in a hollow cylindrical shape to reduce the weight and reduce the weight.

Further, the first to third bed portions 201,
202 and 303 are not limited to only three sections, and may be configured to be divided into a plurality of sections such as four sections. At this time, the first to third bed portions 201, 202, and 303 may be formed of ordinary flat plate members instead of belts or rollers. In addition, the first to third bed boards 20
For the operation of rotating displacement of 1, 202 and 303, a remote control type panel is provided, and this panel is used by the user U.
May be configured to be able to move to a desired position.

In this embodiment, a hydraulic cylinder composed of a cylinder and a rod is used as a drive source. Instead of this, a nut-shaped female screw and a rod-shaped male screw to be screwed into the nut are prepared. May be configured to move in the axial direction relative to the female screw by the rotation of.

Further, a heater may be provided to the apron plate 39 so that when the arm or the like of the user U is inserted from the futon to the apron plate 39, there is no sense of incongruity due to coldness.

Further, as a scope of application, not only bedridden patients but also healthy persons may be used as the case may be.

In addition, the mattresses 51 to 53 are of a three-separation type corresponding to the first and third bed boards 201 to 203. These separate mattresses 51 to 53 are connected by a magic fastener or the like. They may be detachably connected. In this case, it goes without saying that the mattresses 51 to 53 may be continuous and integrated futons.

Further, the free joint 22 of the horizontal bar 16 constituting the quilt lifting mechanism 27 is not limited to this, and may be any one that can transmit rotational displacement, such as a flexible joint.

In addition, in a specific embodiment, the bathtub is a member merely for supporting the first and third bed boards 201 to 203, and may not perform the function of the bathtub. Can be variously changed without departing from the scope of the present invention.

A cover member 206 is adhered under the mattress on the second sleeper plate portion 202 so that when the floating plate portion 10 is lifted from the first sleeper plate portion 201 when the toilet is used. Alternatively, the cover member 206 may be detached in response to the removal of the mattress, and the communication port 205 of the second bed plate 202 may be opened.
