The disadvantages of the conventional lift are fixed type and it requires a separate space for storage. The position of the lift head is fixed so that the body support mechanism may fluctuate or move when the direction is changed and passenger may feel uneasy. In order to solve this problem, first of all, it is necessary to develop a foldable lift that can be folded up when it is not needed, and folded when it is not needed. The next step is to include a sliding feature that allows you to move from bed to a wheel chair or chair. The lift head must be structured so that it can be seated in a wheelchair or a chair precisely outside the bed width of 90cm. To do this, the lift head must be at least 100 cm long and have adequate durability. In addition, the body support mechanism is shaky or rotates to make the occupant uneasy. It is structured so that the direction of the lift head can be placed in the longitudinal direction of the bed, and the flexible device and the spreader bar can support more stably can be resolved.
