ABSTRACT:
A coordinate-type hoist device for lifting a handicapped person and allowing the person to move throughout a room. The device consists of two fixed rails disposed parallel to each other and presumably near the ceiling of the room. Two transverse rails ride along the fixed rails, and a "crab" rides along the two parallel transverse rails. The crab contains a motor arrangement for raising and lowering at least two hoisting straps. By using the apparatus, a handicapped person can sit or lie in a device to which the hoisting straps can be attached. Thereafter the crab motor can raise the hoisting straps to lift the patient, who can then move about the room by moving the crab along the transverse rails, and/or moving the transverse rails along the fixed rails. Alternatively, these crab and rail mvoements can be motor controlled. Limit switches are provided to prevent jamming and overloads, and a low voltage control system is utilized of safety purposes.
