Power lifting toilet chair

Abstract

The power lifting toilet chair is a toilet chair which provides 100% lifting capability for up to a 500-pound obese or elderly or disabled person or recovering hospital patient to sit down on a toilet unaided and to rise unaided after using the toilet. The power lifting toilet chair, which stands over and around an existing toilet bowl, can be used without removal of the existing toilet seat. However, for semi-permanent applications, the existing toilet seat would best be removed. The power lifting toilet chair was designed to be powered either by two electrically-powered actuators ( 12 ) or by two manually-operated non-electric actuators ( 46 ). The non-electric embodiment of the power lifting toilet chair will allow production and use of this invention by elderly, obese or disabled persons or patients in remote or underdeveloped regions without access to electrical power.

1 . A power lifting toilet chair which stands over and surrounds a toilet bowl, comprising: 
 a. a chair frame made of metal, wood, plastic, fiberglass, vinyl or or composite materials, having removable rotatable wheels mounted thereunder for enabling said chair frame to roll about a surface,    b. one or more force-generating devices mounted to said chair frame for producing lifting means, and    c. a plurality of lifting members connecting the force-generating devices to a lifting seat frame, which has a toilet seat mounted on top    whereby said lifting seat frame and said toilet seat with a 500-pound occupant will be lowered gently over said toilet bowl, then lifted gently upward and simultaneously tilted forward from a resting position over said toilet bowl until said occupant arrives at a near-standing position.
