Toilet seat lifter with flusher
First Claim
Patent Images
1. A toilet seat raising mechanism comprising;
- an input line for connection with a water supply line under pressure;
a seat actuator adapted for moving a toilet seat between a lowered position and a raised position in response to changes in the pressure, wherein the seat actuator places the toilet seat in the lowered position when the pressure is at a first pressure level and the seat actuator places the toilet seat in the raised position when the pressure is at a second pressure level;
a first control for causing a first change in the pressure in the seat actuator from a first pressure level to a second pressure level in response to a first activation input;
a second control operating in response to a second input to selectively place the input line in communication with a drain and thereby causing a second change in the pressure from the second pressure level towards the first pressure level; and
a flush actuator for flushing a toilet in response to an operation of the second control.

Abstract
A mechanism for raising and lowering a toilet seat in response to actuation of foot pedals. An actuation cylinder with a contained piston is connected between the toilet bowl and the toilet seat. Water from the supply line for the toilet is routed to the actuator cylinder when a seat up pedal is depressed and causes the piston to extend out of the actuation cylinder and raise the seat. Operation of a flush pedal causes the water within the actuation cylinder to drain so that the toilet seat lowers. A mechanical linkage from the flush pedal to the flush mechanism of the toilet links toilet flushing to the seat lowering action, ensuring that the seat is lowered after each flush.
