Abstract: A hydraulically operated commode seat assembly provides lowering a handicapped person from a standing position to a seated position through a natural range of movement. The assembly includes a hydraulic cylinder that operates on household water pressure. A control device for the hydraulic cylinder which controls the position of the seat. A linkage mechanism connected to a support arrangement for one seat includes a dog leg linkage connected to the hydraulic cylinder. The device is free standing and is designed to have a lifting capacity of 885 lbs. The primary use of the device is in helping physically limited persons to safely and comfortably lower themselves to a sitting position or raise themselves to a standing position with little or no assistance, and this is accomplished by either raising or lowering the pressure in the hydraulic cylinder using the control device.
