However, according to the technique of Patent Document 1, at the time of transfer, it is necessary to incline the horizontal support base toward the wheelchair side with the care recipient on it, so that the care recipient may be heavy or may be covered. There was a risk that smooth transfer would not be possible if the caregiver was in poor health.

Therefore, an object of the present invention is to provide a care bed that allows the care recipient to transfer smoothly while reducing the burden on the caregiver and the care recipient without changing the posture as much as possible.

In order to solve the above problems, the nursing care bed of the present invention includes a bed unit having a floor portion on which the care recipient lies down, a transfer unit having a body holding portion that is detachably combined with the floor portion, and a floor. A plurality of first rods having an elevating mechanism for individually raising and lowering a portion and a body holding portion and a trolley for transportably supporting the floor portion and the body holding portion, and the floor portions parallel to each other through a predetermined gap. It is characterized in that the body holding portion includes a plurality of second rod-shaped members arranged in a gap from the vertical direction by an elevating mechanism.

At this time, the transfer unit may be configured to include a frame that collectively supports a plurality of second rod-shaped members, and the frame may be provided so as to be inclined with respect to the horizontal plane.

It is also possible to configure the trolley to include a first slide mechanism that slides the body holding portion horizontally along the lateral direction of the floor portion.

Further, the transfer unit may be configured to include a support portion that supports the frame and a second slide mechanism that slides the support portion horizontally along the longitudinal direction of the transfer unit.

According to the nursing care bed of the present invention, since the plurality of second rod-shaped members of the body holding portion are configured to be arranged in the gap between the first rod-shaped members from the vertical direction by the elevating mechanism, the body holding portion is provided by the elevating mechanism. It can be separated vertically from the floor. Therefore, it is possible to transfer the care recipient to the transfer unit while maintaining the posture of the care recipient, and it is possible to reduce the burden on the caregiver and the care recipient, which is an excellent effect. In addition, the transfer unit can usually be integrated with the bed unit and can be made compact by using an elevating mechanism.

Hereinafter, an embodiment in which the present invention is embodied in a nursing bed will be described with reference to the drawings. The nursing care bed 1 shown in FIGS. 1 and 2 includes a bed unit 2 having a floor portion 21 on which the care recipient lies down, and a transfer unit 3 provided with a body holding portion 31 that is detachably combined with the floor portion 21. It is composed of a trolley 4 that supports the floor portion 21 and the body holding portion 31 in a transportable manner. In addition, the nursing bed 1 includes a first slide mechanism 6 that slides the body holding portion 31 horizontally along the lateral direction of the floor portion 21. The bed unit 2 includes a pair of inner scissor lifts 24 that raise and lower the floor portion 21, and the transfer unit 3 includes a pair of outer scissor lifts 34 that raise and lower the body holding portion 31.

Here, the pair of inner scissor lifts 24 and the pair of outer scissor lifts 34 function as elevating mechanisms for individually raising and lowering the floor portion 21 and the body holding portion 31. Further, the outer scissor lift 34 and the inner scissor lift 24 are provided in parallel, and when the body holding portion 31 is slid toward the floor portion 21 by the first slide mechanism 6, the inner scissor lift 24 becomes the outer scissor lift 34. It is housed along the inside. The inner scissor lift 24 and the outer scissor lift can hold the floor portion 21 and the body holding portion 31 at predetermined heights, respectively.

The floor portion 21 of the bed unit 2 is composed of a plurality of first rod-shaped members 22 parallel to each other through a predetermined gap 23, and a frame 25 that horizontally supports the plurality of first rod-shaped members 22. Further, the frame 25 is supported by a pair of inner scissor lifts 24.

The body holding portion 31 of the transfer unit 3 is a plurality of frames 35 (35a, 35b, 35c, 35d) that collectively support a plurality of second rod-shaped members 32 arranged in the gap 23 and a plurality of second rod-shaped members 32. ), The arms 36 (36a, 36b) that incline the frame 35a with respect to the floor surface 5, the joints 37 that connect the frames 35 to each other, the joints 37'that connect the arms 36 to each other, and the support that supports the frame 35. A second slide mechanism 39 for horizontally sliding the support portion 38 along the longitudinal direction of the transfer unit 3 is provided with the portion 38 (see FIG. 4). Further, the plurality of frames 35 are provided so as to be tiltable with respect to the horizontal plane, and the frames 35a, 35b, 35c, and 35d are held at different tilt angles.

Next, in the nursing bed 1 configured as described above, a method of separating the floor portion 21 and the body holding portion 31 and a method of transforming the body holding portion 31 into a chair form will be described with reference to FIGS.

As shown in FIG. 3A, the nursing bed 1 is configured by combining the bed unit 2 and the transfer unit 3.
