Automatic toilet seat lid raising and lowering device

Abstract

A toilet seat lid raising and lowering device relies on a motion sensor to trigger its operation. A housing containing the sensor, a motor and a spool is removably attached to a toilet tank. Upon detecting a user approaching the toilet area, the sensor sends an activation signal to the motor causing the motor to rotate the spool. A line is attached to the spool at one end and to the seat lid at a second end such that the rotation of the spool causes the line to raise the seat lid to an open position slightly angled from the tank. Once a user exits the toilet area, the motor returns to a neutral position allowing the spool to rotate in an opposite direction thereby lowering the seat lid by means of gravity. Resistance between the motor and spool prevent the seat lid from “crashing” to a closed position.
