  • Patent number: 4856123
    Abstract: A toilet apparatus for use with bed ridden patients comprises a frame which provides an upper horizontal patient support so that the patient can be transferred from a lying condition in a bed onto the support. A back portion of the support then pivots about a point on a line with the waist of the occupant to define a back portion move to a vertical position and a seat portion rolls along a cam track to a lowered position together with a leg rest portion which pivots downwardly. The occupant therefore takes up the seated condition and can make use of toilet facilities attached to the seat portion. The pivot point retains the center of gravity of the patient at the level of the frame so that little lifting or lowering force is required.
