ABSTRACT:
A conveyance apparatus, and more particularly, an improvement of a transfer aid mechanism which allows a patient to be transferred from a bed to a wheelchair, for example, is disclosed. The transfer aid mechanism according to the invention includes casters disposed at four locations on a frame, and a drive mechanism which is elevatable with respect to the frame. When required, the drive mechanism is lowered to bring its drive wheel into contact with a floor, and when the drive wheel is driven for rotation under this condition, the transfer aid mechanism may be moved back and forth by utilizing the drive wheel alone. Accordingly, a travelling movement of the transfer aid mechanism is facilitated if there is a carpet laid over the floor or there is a step in the floor.
