When rotated, the supporting legs 34 come into contact with the floor surface and the rotating frame 29 is held in a substantially horizontal state. Note that this support leg 34 can also be made adjustable in extension and contraction.

In addition, the reference numeral 35 in the figure is a front screen, 36 is a rear screen, 37 is a lever for switching up and down the cams 21 and 22 for raising and lowering, 38 is a switching lever for the turning cam 10,
Reference numeral 39 indicates a steadying pipe for the pin 32.

Next, to explain the operation of the above example, a urethane mat 40, a mattress 41 and a sheet 4 are placed on the bed 3.
A handicapped person who cannot move with his knees bent is placed on the bed in the center as shown by the solid line in Figure 7, and a comforter is placed over him.

In this state, if you want to turn the patient over for nursing care such as changing sheets or diapers, do the following:

First, to turn over to the right side, turn over cam 10
When the motor 7 is rotated in the direction of arrow B with the switching lever 38 and the motor 7 is reversed, the threaded cylinder 9 moves to the front side in the direction of arrow A, and the bell crank 11a
is actuated to rotate the left rotation pipe 5a in the direction of the arrow C, and swing the right push-up arms 6a, 6a whose bases are fixed thereto upward, to move the center row A of the bed 3. Push up the right side of the bed 3 to make it bend as shown in the imaginary diagram in FIG. Therefore, a disabled person with bent knees who was lying face up on the bed can turn over to the right by tilting the center row A of the bed 3 as shown in the imaginary diagram in FIG. At this time, the knee part will be in a position to extend outward from the bed 3 as shown by the imaginary line in FIG. 43, a blanket, etc., the knee part is supported by this auxiliary bed base 25a, and is kept in an extremely stable state.

In addition, when turning over to the left, it is best to switch the turning cam 10 in the direction opposite to the direction of the arrow B and similarly reverse the motor 7. At this time, the bell crank 11b is operated and the right rotation pipe 5b is rotated. Rotate in the direction of arrow D and push up the left arm 6b, 6b.
This pushes up the left side of the center row A of the bed, causing the sleeping person to turn over to the left. In this case, the knee portion will protrude to the right side of the bed, but the auxiliary bed 25b will receive the knee portion and hold it in a stable state.

Next, to return to the original state, simply rotate the motor 7 in the normal direction to bring the bed base 3 into a horizontal state, and then rotate it a little to the right or left side to return to the horizontal state again. You can return to your position.

In addition, to explain the operation of the auxiliary bed bases 25a and 25b of other examples shown in FIGS. 4, 5, and 6, in a normal state, the rotating frame 29 is set upright and the pin 32 is fixed. It is inserted into the locking hole 33 of the frame 28 and fixed, and used as a safety frame.
At this time, the supporting legs 34 are held suspended from the lining frame 31.

Next, when turning over, remove the pin 32, rotate the rotation frame 29 together with the lining frame 31 outward, and set the supporting legs 34 upright on the floor, as shown in FIG. The rotation frame 29 is set to maintain a substantially horizontal state. Then, by placing a cushion 43, a blanket, etc. on this rotating frame 29, and turning the person with bent knees to this side, this rotating frame 29 can be used as the aforementioned auxiliary bed base. Next, when the safety frame is not used, by pushing the supporting legs 34 below the bed frame 3 and rotating the rotation frame 29 further outward and downward from the horizontal position, the dual-purpose safety frames 26a and 26b can be moved to the outside of the bed frame 1. It can be hung and stored in the room, making nursing easier.

Next, to raise the upper body of a sleeping person,
Pin 1 that fits into cam hole 22a of cam 22 for up-and-down
6a is pushed up by the lever 37 to engage the stepped portion, and the motor 7 is reversed to move the threaded cylinder 9 in the opposite direction of arrow A to the rear side beyond the front-rear intermediate position of the threaded shaft 8. Drive arm 16, pipe 1
7. The front rotating pipe 13a is rotated in the direction of the arrow H via the interlocking arm 18, the rod 20, and the arm 19, and the bed 3 is rotated by the front push-up arms 23, 23...
The front side A row part of is bent upward. For this reason,
It can raise the upper body of a sleeping person.

In addition, when it is desired to swing the leg side upward, a pin 15a that fits into the cam hole 21a of the cam 21 for raising and lowering is used.
When the lever 37 is pushed up to engage the step part and the motor 7 is reversed as described above, the rear rotation pipe 13b is rotated in the direction of the arrow via the drive arm 15. The side d-row portion is pushed up by the rear push-up arm 24, and the leg side can be swung upward.

As described above, with the above-described structure, a disabled person whose knees remain bent can be easily turned over by bending the bed, and the knee can be easily turned over when the patient is turned over. Even if a part of the knee protrudes from the bed, this knee part can be supported by the auxiliary bed, and the person with a disability can be kept in a comfortable tossing and turning position without becoming unstable.
The effect is such that the safety of the bed for turning over can be sufficiently ensured.
