Abstract: The present invention includes a floor mounted toilet with a mechanical lift device comprising an adjustable linkage assembly connected between a foot pedal and a torque arm of a torque rod. The torque rod is affixed to the toilet seat to rotate the toilet seat. Applying a pedal force raises the toilet seat to a raised seat angle. A floor mounted base member rotationally supports the foot pedal and rigidly supports a vertical member carrying a pivot plate of the linkage assembly to rotate about a pivotal axis. The initial force to raise the toilet seat is adjusted by changing the first length of an upper rod of the linkage assembly. The raised seat angle is adjusted by the second length of a lower rod of the linkage assembly. The first and second lengths are adjusted by providing length adjusting devices, such as a turnbuckle.
