The sliding member made of leather or synthetic rubber is provided on one end surface between the end surface and the concave arc end surface of 0b or on both end surfaces to facilitate smooth rotation of both.

 Next, the operation of the above example will be described in detail.

A handicapped person or an elderly person sleeps on the bed 20 with the upper half of the body on the front bed 20a side from the waist and the legs on the rear bed 20b in an upward state. From this lying posture, the posture of raising the upper body and eating or the posture of descending to the floor 41 side on the right side (the left hand side when the person sleeping in the upward direction is the target), or the caregiver on the right side carry or carry it up. When the user wants to take a posture to move, the cam pin 19 is previously inserted into the left hole 18a of the lateral frame 18 as shown in FIGS. 6 and 7, and the screw shaft 12 is rotated counterclockwise by the motor 10 to rotate the screw cylinder 13 To move forward. Then, first, the cam roller 35 mounted via the bracket 33 on the side of the waist support frame 21a becomes the cam body.
The cam roller 36, which is scooped up by 37 and is attached to the back support frame 21b side via the bracket 34, comes into contact with the front surface of the cam body 38 to support each as shown in the operation steps of FIGS. 16 to 18. The frames 21a and 21b are rotatably actuated so that they are in the posture shown in FIGS. 21 and 22 in which the upper body for eating or reading is raised. Incidentally, if only this posture is adopted, it is not necessary to insert the cam pin 19 into the hole 18a or 18b.

Next, the motor 10 is further rotated from this state to
When 13 is moved forward, the cam pin 19 is fixed to the bed fixed frame 1
The fixed cam 9a on the left side is brought into contact with the displaced portion in the cam groove (a) and the motor 10 is mounted as shown in FIG. 15 from the state of FIG. 13 through the state of FIG. The frame 16 and the rotating frame 6 integrated with the frame 16 rotate to the right side (arrow E side) with respect to the fixed frame 1 to the state shown in FIGS. 12 to 15. When the state shown in FIG. 14 is reached during this rotation, the relative position between the cam rollers 35, 36 and the cam bodies 37, 38 is in the state shown in FIG. 18, and when the screw cylinder 13 is further advanced, The drive side including the motor 10 integrated with the frame 6 side rotates about 45 degrees from the state shown in FIGS. 14 to 15 and about 90 degrees from the initial state. Then, at the time of the final rotation of about 45 degrees, the relative position between the cam rollers 35 and 36 and the cam bodies 37 and 38 is operated from the state shown in FIG. 18 to the state shown in FIG. At the same time that the frame 21b side is slightly rotated rearward, the waist receiving support frame 21a side becomes slightly rearward, and then the back receiving support frame 21b side stands up again and at the same time the waist receiving support frame 21a side becomes horizontal. That is, the sleeping person finally goes into the posture shown in FIG. 23 through the state shown in FIG.

Incidentally, in order to return the original bed from the posture shown in FIG. 23 so as to be in the front-back direction, the motor 10 is rotated to the right (reverse rotation to the above), and the operation reverse to the above is carried out. You can keep the posture as it is. In addition, in order to reverse the rotating frame 6 and reverse the standing side, the cam pin 19
It is advisable to thrust the into the other hole 18b and fit it into the cam groove (b) of the right fixed cam 9b.

Therefore, in the operating process of the front bed 20a from FIG. 22 to FIG. 23, the waist support frame 21a and the back support frame 21b are operated to the state shown in FIGS. 18 to 20 as described above. Therefore, the person on the couch swings the thigh portion near the waist on the couch supported by the distal end side of the waist support frame 21a slightly upward, and the foot side is entirely fixed on the rear couch part 20b on the fixed side. Not only is it prevented from rotating while being rubbed, but also the foot on the side opposite to the rotating direction is prevented from being caught by the rear bed 20b, which is the fixed side, and twisting the foot. Also, at this time, if only the waist support frame 21a is swung up, the person on the bed will be excessively bent and will have difficulty,
The back support frame 21b is slightly tilted rearward, and then the waist support frame 21a is returned to the horizontal state, and at the same time, stands upright again.

Therefore, it is possible to raise the back of a person sleeping in the posture shown in FIG. 22, and finally turn the bed to the side of the bed and lower the feet to the floor as shown in FIG. Then, in order to get off on the floor in the posture shown in FIG. 23, the rotating handrail portion 29b on the rear end side of the handrail 29 is operated as shown in FIG. When set by hanging, the rotating handrail portion 29b approaches the left and right sides of the person who is going to stand up, so that the rotating handrail portion 29a is gripped and the power of the hand makes it possible to easily stand up while shifting the body away from the bed.
