  • Portable patient conveyor and methods related thereto
    Patent number: 7540043
    Abstract: This patent document discusses assemblies and methods for transferring a subject from a first surface to a second surface. In varying examples, an assembly includes a first roller and a second roller. An assembly frame rotatably supports the rollers and, in some examples, longitudinally extends from a frame first end to a frame second end. A belt is coupled to the first and second rollers in such a matter that the assembly frame is positioned, at least in part, between the rollers and surrounded by the belt. A motor, powered by a power source, is coupled to the belt via the first or second roller. In one such example, the motor is coupled with a portion of a first roller inner surface. In another example, an outer surface of one or both of the rollers include belt driving projections matable with projection receiving portions disposed on a belt underside surface.
