いるのが実情である。<<Prior Art>> For wheelchair users with lower limb disabilities, transferring between a wheelchair and a bed is one of the most difficult daily tasks. In these tasks, those with healthy upper arms can perform independent transfers by training their hands and arms, but they are often accompanied by risks such as falls and falls. For this reason, people living in wheelchairs often require the assistance of a caregiver, and the caregiver usually picks them up or carries them in their arms, which puts a heavy burden on the caregiver. be.

従来、これらの移乗を助ける補助装置として、
天井走行あるいは床走行のリフト装置等があり、
これらによつてベツド、車椅子の移乗が行なわれ
ている。 Conventionally, as auxiliary devices to assist with these transfers,
There are lift devices that run on the ceiling or on the floor.
These are used to transfer people to beds and wheelchairs.
