Benefits of technology

"This invention is a toilet chair that can help elderly, disabled, or obese people stand up after using the toilet. It can lower a person onto the toilet and then gently lift them up to a position where they can stand up. This invention can restore self-reliance and dignity to people who have difficulty rising from a toilet seat or chair. It can also reduce the time and effort of caregivers, hospital assistants, or rest home nurse managers."

Problems solved by technology

The search of prior art has revealed only assisted-lift toilet chairs, using spring-loaded devices, which can only offer partial assistance to a person attempting to rise from a toilet seat.
None of the prior art devices offers 100% lifting capability.

Embodiment Construction

Preferred Embodiment FIGS. 1,2,3,4

[0040] The search of prior art revealed only spring-assisted toilet chairs, which provide only partial lifting assistance when a person attempts to arise from the seated position on a toilet. We found no toilet chair in existence which could lift 100% of a 500-pound person's weight to a near-standing position. This invention, which is powered by two electrically-powered actuators, permits an elderly, disabled or obese person to sit down and arise from a toilet seat by simply moving the electric switch to the UP or DOWN positions. The toilet seat of the power lifting toilet chair is mounted on top of a power lifting seat frame, which is lifted upward and tilted forward by two actuators attached to each side. The actuators and lifting linkages are positioned such that the power lifting toilet chair can be placed over and around a toilet bowl and operated without touching the toilet bowl. The actuators are suspended by brackets from the main chair cros...

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.
