Note that the lowermost end of the backrest portion 1 including the convex portion may be slightly rounded with a slight gap between the end surfaces of the footrests 21, 22, and 23 so as not to interfere with the tilting.

Depending on the weight distribution centering on the support shaft 3 between the convex portion of the backrest 1, ie, the central buttocks 11, and the back portion, the center of gravity may be changed to the central buttocks 11 when the patient gets up from the reclining horizontal state.
It is conceivable that the backrest can be tilted by the patient's own weight by the seesaw action. In this case, a power unit for inclining the backrest is not required, and only a stopper mechanism with a release for holding in a horizontal state is required. Therefore, the manufacturing cost can be extremely reduced.

With regard to the provision of means for the center footrest 21 to slide in the direction of the end of the bed, in the embodiment the slider rail 6 with rollers 61 is provided in order to obtain a smoother operation, but merely a slide. A simple guide may be used if only this is done, or this kind of slide mechanism can be omitted altogether if the mat frame material of the center footrest 21 is made slippery. This is effective in further reducing costs.

FIG. 4 is a perspective view showing a state in which the triangular band-shaped cloth is attached by rolling up the cloth. As shown in FIGS. 8 (a) and 8 (b), this mat has a triangular shape as an elongated triangular band-like sheet having a lower end as an apex at a center position of a surface of the mat lower surface portion S2 facing the mat. The belt-like cloth N is attached by sewing. By doing so, the excessive force concentrated on a part of the bedsheet during use is not applied, so that the durability of the bedsheet can be improved.

As another embodiment, the toilet lid 95 may be provided below the inclined toilet seat 92. Thus, the presence or absence of a toilet can be arbitrarily determined while the backrest 1 is inclined.

An operation process in one embodiment of the present invention will be described below with reference to a sketch. FIG. 9 (a) is a perspective view showing a state of a bed in a normal plane to which a mat according to the embodiment of the present invention is attached.
The connection portions are slightly overlapped, so that the user can use the bed with a toilet bowl in almost the same manner as a conventional bed. FIG. 9 (b) is a perspective view showing an initial process in which the backrest is tilted to enter a use state when the stool is attached to the stool according to the embodiment of the present invention. The center of the lower limb is pushed down toward the lower end of the bed. FIG.
(C) is a perspective view showing a state in which the center of the bed is depressed in the process proceeding from FIG. 9 (b), in which a rectangular hole H is formed in the center of the bed such that the buttocks of the patient fit. Can be. FIG. 9 (d) is a perspective view of the final process from FIG. 9 (c), and shows a state in which the backrest of the bed is sufficiently tilted, the inclined toilet seat at the time of stool appears, and the mat is removed from the surroundings. ing. Here, as a result of many studies, the present inventor has found that the upper and lower bedspreads are formed to hang down or be stretched in an optimum condition, and that the stool is restored naturally after stool. .

Since the above structure is used, when using this, first, the backrest 1 is gradually raised and tilted to form a rectangular hole H at the center of the bed in which the buttocks of the patient fit. can do. When the center footrest 21 is further slid toward the end of the bed, the rectangular hole H expands in the longitudinal direction of the bed. In this formed rectangular hole H,
The defecation device 9 is installed so that the inclined toilet seat 92 that forms a substantially right angle with the seat or the inclined backrest portion 1 from below serves as a bottom. As a result, the user's buttocks feel as if they were completely fitted into the bowl, and the elbows have a sufficiently stable posture as the edges of the rectangular holes in the bed act as armrests, making it a truly comfortable and comfortable feeling. become. Therefore,
There is no need for any safety belts or armrests used in the prior art.

Further, since the backrest portion is inclined upward, the patient does not lean forward, and since the seat is an inclined toilet seat that is substantially perpendicular to the backrest portion 1, it is substantially normal while standing upright. Since the patient is seated on a chair, the patient's body position is stabilized, especially when the stool is used, and a feeling of mental stability can be brought about, so that defecation can be performed smoothly.

Also, since the backrest rotates about the lower edge excluding the protrusion as a support shaft, the backrest acts to naturally tilt by the action of the lever due to the weight of the patient on the protrusion. A very small source will suffice.

Further, when the backrest portion is returned to a horizontal state while being tilted, the two-part mattress is fixed to the upper end portion and the lower end portion of the bed so as to always pull the bed from the corner of the bed toward the center, and to wrinkle. It can return to the original state without being affected.

When the present invention is used, it is used according to the following procedure. 1) For toilets, open the toilet lid. 2) Incline the backrest. 3) Slide the center footrest. Not required if linked with 1). 4) Sit down on the inclined toilet seat and use it. The backrest tilt angle is adjusted as desired by the patient who is the user. It has been found by the present inventors that the angle with the toilet seat at this time is generally preferably about 100 degrees. 5) After the service is completed, it can be restored by operating in the reverse procedure. At this time, the mattress also automatically returns to the original horizontal level without unnatural wrinkles.

[0032]

The most important thing is that a patient who cannot move does not need to take care of his / her hands and can lay up and use the stool.
The adoption of a seesaw mechanism in the inverted convex backrest allows the patient to slide into the bed hole from the inclined backrest like a seesaw, making the patient's posture in the bed during use more stable. It can be manufactured easily and inexpensively because of its simple structure.

The provision of the inclined toilet seat that is substantially perpendicular to the inclined backrest allows the most natural and comfortable use posture.

By performing at least the sliding operation of the center foot rest portion in conjunction with the tilting operation of the backrest portion,
The operation can be facilitated, the number of power sources to be operated can be reduced, and the manufacturing cost can be further reduced.

By dividing the mattress into two pieces and sewing the wide rubber across the bed and mounting the two pairs of wide rubber pieces in an inverted C-shape, the mattress on the bed is always intact and the backrest portion is used at an angle. It is automatically removed according to the area around the toilet seat only when the toilet is used, and the mat can be covered with a mat after use to restore a horizontal bed.

Buttons are fixed to the mat at three places along the upper edge of the backrest on the back of the upper limb of the bedcloth, and are fixed to the mat at two places at the upper end near the center of the lower back of the lower limb and one place at the lower end. By attaching the button, it can be turned up, returned and restored almost completely after use, automatically and without wrinkling of the mattress.

Further, by suturing an elongated triangular band-shaped cloth at the center of the back side of the lower limb of the laying cloth, an excessive force concentrated on a part of the laying cloth during use is not applied, so that the durability of the laying cloth can be improved. .
