Abstract
A seat lifter attachment for a toilet base including a mounting bracket resting on and attached to a rear upper surface portion of said toilet base by clamping action of a toilet seat and a second portion extending downwardly along one side of said toilet base. A first pivot fixedly has an axis extending outwardly from the second portion and a second pivot is mounted on and extends outwardly from the second portion. A pivotal actuator lever arm is mounted for pivotal movement on the second pivot and toilet seat lifter is pivotally mounted on the first pivot for pivotal movement on the second pivot and is engageable with the toilet seat for effecting movement of the toilet seat from a lower horizontal position to a lifted vertical position in response to the pivotal movement of the pivotal actuator lever arm. A displacement motion multiplying drive connection between the actuator lever arm and the pivotable toilet seat lifter causes rotation of the pivotable seat lifter through a rotation displacement approximately double rotation of said actuator lever arm.
