Abstract
Abstract This disclosure pertains to an aid for invalids facilitating their ability to be seated and unseated from a water closet utilizing a pair of horizontally disposed arm rests and a hinged commode seat whose elevation and angular position above the water closet is under the manual control of the invalid. A manually operated lever enables a spring to bias the arm rests and the seat in an uppermost position for use by the invalid in the standing position. Manipulating the lever permits the arm rests to descend and the seat to assume a horizontal position with the spring resisting the downward forces exerted on the arm rests and the seat, by the user, as he is gently lowered into a seated position. Re-manipulation of the lever causes the spring to urge th arm rests in an upward position, and the seat to assume a near vertical position thereby aiding the invalid to achieve a standing posture.
