  • Toilet seat lifter with flusher
    Patent number: 6907621
    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.
