Abstract: A compact powered lift toilet for assisting a person in rising from or being seated upon a toilet by duplicating the natural motions of the human body. The toilet set accomplishes three separate motions simultaneously: (1) vertical translation, (2) horizontal translation, and (3) rotation. A sun and planet gear mechanism lifts and moves forward the front of the toilet seat while a lever action on the rear of the toilet seat causes the rear of the seat to rise and tilt forward with respect to the front of the seat. Both the sun and planet gear and the rear lever action are effected by a single linear actuator.
