[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A care bed according to the present invention will be described below with reference to an embodiment shown in the drawings. FIG. 1 shows an example of a nursing bed according to the present invention, in which a bed body 1 is divided into a left and right half-bed section 1A integrated with the main body and a movable half-bed section 1B. It has a configuration.
End plates 2 and 3 are provided at front and rear ends in the longitudinal direction, and side plates 4 and 5 are attached to both left and right sides.

[0008] Of the left and right half-bed portions 1A and 1B, the movable half-bed portion 1B is supported by a chassis 6, and a pair of left and right casters 7, 7; , 7 are attached. As shown in FIG. 2, the half-bed portion 1B is detachable from the half-bed portion 1A integrated with the main body, and can be moved to an arbitrary position via the chassis 6.

When the half bed portion 1B is mounted on the half bed portion 1A side, fixing stoppers 8, 8 are provided on the main body side to fix the position. The side plates 5 of the half bed portion 1B are provided on both left and right sides, and these side plates 5 and 5 have a lower end side as a pivot point (rotation fulcrum). , And a position that hangs down (hanging position).

The half-bed portion 1B which can be separated from the main body as described above can be used as a stretcher while maintaining a horizontal bed shape. (FIGS. 3 and 4), a sofa (FIG. 3), a reclining bed, and the like.

Since the half-bed portion 1B functions as a wheelchair, a sofa or a reclining bed, the middle portion in the longitudinal direction is divided into a seat portion 10, a head portion from the seat portion 10 is a back portion 11, and a lower portion is a lower limb portion 12. ing. Further, as shown in FIG. 3 and FIG.
5, the upper limb 12 is turned upright with the boundary with the seat 10 as a rotation fulcrum, and the lower limb 12 is rotated at the boundary with the seat 10 by a rotation of the handle 16. It is designed to hang down.

When the vehicle is in a wheelchair state as shown in FIGS. 3 and 4, the left and right side plates 5, 5 become armrests, and the end plates 3 are provided.
Is also used as a footrest. In addition, cutout holes 13 are provided on the left and right sides on the upper end side of the back portion 11, and these cutout holes 13 serve as a push portion of a wheelchair.

In the nursing care bed of the present invention described above,
When the half bed units 1A and 1B are in the mounted state,
When the back portion 11 of the half bed portion 1B is to be erected, it is preferable that the back portion of the half bed portion 1A is also erected at the same angle at the same time. In addition, half bed part 1A and 1B
It is preferable that the height can be adjusted by simultaneously moving the entire height up and down in a state where the two are mounted on each other.

FIG. 5 shows the back 11 and the lower limb 1 described above.
2 illustrates an example of a mechanism for refracting and displacing 2.
As shown in FIG. 5, a gear box 17 is fixed on the chassis 6, and a portion of the seat 10 of the half-bed portion 1 </ b> B is supported thereon via a support 20 and a cam 21. The gear box 17 incorporates a reduction gear group (not shown), and the above-described turning operation handles 15 and 16 are attached thereto. The telescopic link 18 is provided between the rear end of the gear box 17 and the back surface of the back part 11.
7 between the front end of the lower leg 7 and the back of the lower limb 12
The telescopic link 18 is formed by a pair of links 18a and 18b screwed together in the longitudinal direction, and the telescopic link 19 is formed by a pair of links 19a and 19b screwed together in the longitudinal direction. The relative rotation between them causes expansion and contraction via screwing.

In the operation mechanism described above, the handle 15
Is rotated, the rotational force is transmitted to the telescopic link 18 via the reduction gear in the box 17. In the telescopic link 18, the link 18a or 18 is connected via a bevel gear (not shown).
b, the rotational force is transmitted to both links 18a, 18b.
Moves relative to each other in the axial direction through mutual screwing, and the telescopic link 1
The overall length of 8 is expanded and contracted. When the telescopic link 18 is extended from the state shown in FIG. 5, the back portion 11 in the horizontal state stands up until the angle α with respect to the horizontal direction becomes 90 degrees. The upright angle α can be adjusted to an arbitrary angle within a range up to 90 degrees by the number of rotations of the handle 15.

When the handle 15 is rotated, the cam 21 also rotates 90 degrees, and the front side of the seat 10 is tilted upward. At this time, the inclination angle γ with respect to the horizontal direction is not particularly limited, but is preferably set within 40 degrees. The inclination of the seat portion 10 is such that when the handle 15 is rotated in the reverse direction to return the back portion 11 in the horizontal direction, the seat portion 10 returns to the horizontal state in conjunction with the rotation.

When the other handle 16 is turned,
As in the case of the telescopic link 18, the rotational force is transmitted to the telescopic link 19 via the reduction gear. In the telescopic link 19, since both links 19a and 19b are screwed together, they relatively move in the axial direction, and the entire length of the telescopic link 19 expands and contracts. When the telescopic link 19 is contracted from the state of FIG. 5, the lower limb portion 12 hangs down until the angle β with respect to the horizontal direction becomes 90 degrees. The hanging angle β can be adjusted to an arbitrary angle within a range up to 90 degrees by the number of rotations of the handle 16.

The above-mentioned back 11, lower limb 12, and seat 10
Is an example of a case where the handles 15 and 16 are manually operated, but these may be electrically operated.
The telescopic links 18 and 19 do not necessarily need to be a combination of mutually screwing links, and for example, a hydraulically operated cylinder may be used.

Since the nursing care bed of the present invention is configured as described above, when the standing angle α of the back 11 and the hanging angle β of the lower limb 12 are bent to a large angle, the half bed 10
Can be turned into a wheelchair, can be turned into a sofa when bent at a slightly smaller angle, and can be turned into a reclining bed when bent at a smaller angle. In addition, the back 11 and the lower limb 12
When it is horizontal with 0, it can be a stretcher.

According to the nursing care bed of the present invention, when the patient on the bed is to be transferred to a wheelchair or the like, it may be slightly laterally moved in the width direction while lying down. Since it is only necessary to perform an operation for changing the shape, the transfer operation of the patient can be easily performed without heavy labor.

[0021]

As described above, according to the present invention, one half of the bed can be separated, and the half bed portion is divided into a seat portion, a back portion, and a lower limb portion. Since it is possible to hang down and function as a wheelchair, it is possible to transfer the patient to the wheelchair only by slightly laterally moving the patient on the bed in the width direction. Further, the half bed portion can be used as a sofa or a reclining bed by arbitrarily adjusting the standing angle of the back portion or the hanging angle of the lower limb portion, or can be used as a stretcher by keeping the whole flat surface.
