ABSTRACT:
A device for assisting invalids into and from a seated position, e.g., over a toilet. The device has a frame and a seat hingedly attached at the front thereof to a support member which is vertically slidable on the frame. A stop is associated with the hinge to prevent the seat from pivoting below the horizontal attitude. An extendable arm is connected at one end to the frame and, at the other end thereof, to the seat between the hinge and the center of gravity. Control means selectively activates extension of the arm to initially vertically elevate the seat in the horizontal attitude, and then to pivot the seat upwardly to assist an individual seated thereon into a standing position; or activates retraction of the arm to initially pivot the seat into a horizontal attitude, and then to vertically lower the seat in a horizontal attitude to assist an individual into a seated position. The extendable arm may be electrically, pneumatically or hydraulically operated, and the device may be portable and adapted to be positioned over a conventional toilet.
