  • Publication number: 20210330524
    Abstract: A transport apparatus has a mobile chassis, a lifting mechanism, two armpit supports structured and operated mirror-symmetrical to one another, and two seat assemblies. The lifting mechanism includes a lifting arm for assembling a chest rest and two lifting racks, and a linear actuator driving the lifting arm to pivot upward or downward. The armpit supports are assembled on the lifting racks and transversely extend toward a rear of the mobile chassis. The seat assemblies are assembled on the mobile chassis. Each of the seat assembly has a seat plate driven to rotate by a drive motor to form a seat. The weak person can be moved directly by the transport apparatus with voice command or with a remote control. Since the weak person is not moved by the care workers, the weak person can be moved in an easier and safer way.
