At this time, since there is no relative speed difference between the sick person and the belt 7 of the wheelchair or the bed and between the belt 7 and the telescopic floor means 4A or the telescopic support means 4, no frictional resistance is generated. In addition, the body can be smoothly replaced without rubbing or damaging the body or shifting its position.

The telescopic support means 4 of the wheelchair is completely shortened,
When the telescopic floor means 4A of the bed is completely extended, the sick person or the like is put on the bed from the wheelchair. Thereafter, the wheelchair is pulled out from the front end of the bed, and a horizontal handrail frame is attached to the front of the bed. When a futon or the like is used, if the sick person or the like and the futon are used as a set in a bed and a wheelchair, the above-described smooth transfer can be maintained. However, although it takes a lot of time for mounting, it may be used only on the bed.

Contrary to the above, when the sick person or the like is transferred from the bed to the chair, the above procedure is reversed.

[0061]

According to the first aspect of the present invention, when an object located at a specific position on one mounting device is replaced with a specific position on another mounting device, the object is lifted and moved. With little artificial force without the need to perform any action such as letting it (ie, without changing the position and orientation of the article on the device)
Labor saving can be performed.

According to the second aspect of the present invention, when transferring a sick person or the like with reduced motor function from one of them to the other between a bed and a wheelchair, the sick person or the like is lifted and moved. It can be performed labor-saving with small artificial power without requiring any action such as making the patient sick, etc. In this case, since the posture change of the sick person etc. on the bed or wheelchair is hardly necessary, a large posture change is prohibited.
