9. The control unit that controls the solenoid, and can perform various controls such as sequence control and microcomputer control. Therefore, the bed according to the present embodiment can of course be remotely operated, and for example, a design can be made in which all the operations are automatically performed by pressing the "carry for sick person" button on the remote controller.

Since this embodiment has the above-mentioned structure, the following operational effects are exhibited.

A sick person sleeps on the bed in a state where the wheelchair and the bed frame 1 are fitted and connected to each other and the bed surface is flat.
In this state, the column 27 with casters is grounded on the floor surface.

The base frame 31 of the wheelchair is positioned at a predetermined position of the bed, that is, below the sick person placing portion 10 constituting the bed. Then, the sick person is positioned on the sick person placing portion 10.

Subsequently, for example, a signal is sent to the control unit 58 by remote control, and the motor 29 is operated by the signal from the control unit 58 to extend the four lifting legs 28 and raise the bed to a predetermined height. The telescopic rod 22 is extended and the L-shaped arm rod 24 is activated to tilt the U-shaped frame portion 16 to a desired angle. At this time, the hook rod 53 pivotally attached to the gripping rod 33 is locked to the upper rod of the backrest portion 7, and the projecting and retracting rod 50 is a locking pin.
Since it is not located between 46, the backrest 7 is in a free state. Therefore, as the U-shaped frame portion 16 tilts, the backrest portion 7 also tilts at the same time. Then, a signal from the control unit 58 causes the motor 29 of the lifting leg 28 to
, The bed frame 1 is lowered, the support body 45 is placed on the receiving body 43, and the pin 47 is fitted into the locking receiving body 44 to form a wheelchair, and the bed frame body 1 is further lowered. Then, the lateral rod 5 and the lateral rod fitting portion 6 are disengaged from each other, and the bed frame 1 and the wheelchair are separated.

Then, the solenoid is operated in response to a signal from the control section 58 so that the locking rod 20 projecting by projecting the footrest 9 is immersed, and then the locking rod 21 is manually pushed on the wheelchair. The upper swinging body 32 and the lower swinging body 42 are slid out from the receiving hole 59, the left and right levers of the lower swinging body 42 and the locking rods 38 of the projecting frame 37 are locked to bend the foot rest 9.

Subsequently, the hook 53 and the upper bar of the backrest 7 are unlocked, the projecting and retracting bar 50 is positioned between the desired locking pins 46, and the backrest 7 is fixed at the desired angle.

Then, the wheelchair is pulled out from the introduction opening 3 of the bed frame 1. In this case, the wheel assembly of the wheelchair 41
Wheel and the rear wheel 34 are grounded, and the steering wheel 36
Since it is not grounded, the wheelchair can be pulled out linearly from the bed frame 1. Further, since the guide roller 49 is in contact with the guide rod 48, the wheelchair can be reliably pulled out linearly also at this point.

[0037] When the wheelchair drawer is completed, pedal 40
The wheel of the pedal 40 is lifted by pressing, and the wheelchair is supported by the front and rear wheels 34 and the steering wheel 36, and the sick person is transported to a desired place by the wheelchair. At this time, since the steered wheels 36 are pivotally supported by the curved support rod 35 which is curved rearward, the straightness of the wheelchair is maintained.

When the sick person put on the wheelchair returns, first, the motor 29 is operated by the signal from the control unit 58, the elevating leg 28 is contracted to lower the bed frame 1, and then the pedal 40 is depressed to depress the pedal 40. The wheels are grounded and the steering wheels 36 are floated. In this state, the wheelchair is pushed to introduce the wheelchair into the bed frame 1 through the introduction opening 3, and the stopper plate 54 contacts the front surface of the lateral rod fitting portion 6. Stop pushing the wheelchair at the contact position. In this position of the wheelchair, the lateral rod 5 of the wheelchair is located above the lateral rod fitting portion 6 of the bed frame 1.

In this state, when the motor 29 is operated by the signal from the controller 58 to raise the bed frame 1, the pin 47 is moved.
Is disengaged from the lock receiving body 44 and the wheelchair base frame 31
When the bed frame 1 is further raised, the horizontal rod 5 and the horizontal rod fitting portion 6 are engaged with each other to connect the patient placement portion 10 and the bed frame 1 to each other. To be done. In this state, the gripping rod 33 is moved, the hook rod 53 is locked to the upper rod of the backrest portion 7 and the projecting and retracting rod 50 is pulled out from between the locking pins 46, and the backrest portion 7 is set in a free state, and is set at a predetermined angle. The backrest 7 is brought into contact with the fixed U-shaped frame 16.

Subsequently, the engagement between the locking rod 38 and the left and right levers of the lower sliding body 42 is released to bring the seat 8, the upper sliding body 32, and the lower sliding body 42 into a flat state, and the locking rod is fitted into the receiving hole 59. 21 is inserted and the foot rest 9
The foot rod 9 so that the locking rod 20 does not bend.
Is mounted on the locking rod 20 and supported. Next, the upper half of the bed, which is composed of the backrest portion 7 and the U-shaped frame portion 16, is slid by a signal from the control portion 58 to flatten the bed surface, and the bed frame body 1 to a predetermined height. A series of operations are completed by lowering.

When the telescopic rod 23 is moved by a signal from the control unit 58, the L-shaped arm rod 26 is slid, and the slidable L-shaped arm rod 26 swings the upper body 25a to move the upper body 25a and the lower body 25b. The pivoting portion of and moves upward, the lower body 25b slides on the mounting plate body 18 toward the bed head mounting portion side, and the bending body 25 bends. The upper body 17a connected by the connecting rod 19 is also moved by the movement of the upper body 25a, so that the left and right bending bodies 17 and 25 are simultaneously bent upward and the lower body 17a is bent.
b and 25b slide to the bed head mounting side. This bent body 17
With the bending of 25 and sliding of the lower bodies 17b and 25b, the locking rod 20
As a result, the foot rest 9 of the wheelchair, which is placed on the bending bodies 17 and 25 and is connected by fitting the lower bodies 17b and 25b and the receiving holes 59, is also bent.

Therefore, even if the backrest portion 7 and the U-shaped frame portion 16 tilt, the sick person on the bed can be firmly held in position without sliding.

[0043]

Since the present invention is constructed as described above,
When moving a sick person who is sleeping in a bed to a desired place, the sick person can be made to sit in a wheelchair even if the caregiver does not hold the sick person, and thus the sick person can be placed without any burden on the sick person. (EN) Provided is an excellent bed-fitting wheelchair that can be moved.
