## Abstract

The invention provides a mechanism to lift a toilet seat. A depressable foot pedal connects to a rod which rod is connected to the lid of the toilet seat. When the pedal is depressed, the rod lifts and thus lifts the lid of the toilet seat. A second depressable foot pedal connects to a second rod which is connected to the toilet seat. When the second pedal is depressed the rod lifts and thus lifts the toilet seat.

## Claims

### Claim 1

A hands free toilet device, comprising:
a toilet having a back, a base and two sides; two paper dispensers; a first depressable foot pedal connecting to a first rod which first rod is connected to a lid of a toilet seat and a second depressable foot pedal connects to a second rod which rod connects to the toilet seat,
wherein depression of a first depressable pedal lifts the first rod which lifts the lid of the toilet seat and wherein depression of the second depressable foot pedal lifts the second rod which second rod lifts the toilet seat, and wherein the lid of the toilet is attached to a tank or to the center portion of a pivot between toilet seat hinges and wherein the device further comprises two lever extensions at the back, one extension on each side of the toilet seat, and wherein each extension uses toilet seat hinges as fulcrum to lift the toilet seat, and wherein the extensions guide paper towards the toilet seat from the paper dispensers at both sides of the toilet at the base of the tank.

### Claim 2 (depends on 1)

The hands free toilet device of claim 1 further comprising weights at the ends of the extensions wherein the weights at the ends of the extensions serve as counterweights for the toilet seat, and wherein the extensions hold a link for a cylindrical rod folded to work as a cam, and wherein this folded rod connects the extensions with a pedal at the bottom side of the toilet bowl,
wherein a portion of the folded rod is displaced up and down through a static ring connected to the toilet bowl, and
wherein the folded portion of the rod operates as a cam and produces a semicircular movement at a top of the rod, and
wherein the top of the rod becomes a follower that pulls the extensions down to the side by a second cam mechanism between the top part of the rod and the link.

### Claim 3 (depends on 2)

The hands free toilet device of claim 2 wherein the distance from the link to the hinges is proportional to the size of the folded portion of the cylindrical rod, wherein the rod portion acts as a cam directly connected to the extensions, and the cylindrical rod is straight and works as a follower between the lever and the extensions wherein the top part of the rod works as a follower and the cam works as a link creating one single cam mechanism.

### Claim 4 (depends on 1)

The hands free toilet device of claim 1 having one extension, one cam, one follower and no static ring, and wherein a folded rod or the straight rod is pulled down at the bottom by a lever having an axis as fulcrum and an angle less than 180 degrees, and wherein the lever transports the force from the toilet bowl to perpendicularly below the link that is attached to the extensions, and wherein this lever has a pedal at the front of the toilet where force is applied, and the axis runs through the bottom side of the toilet bowl, and when force is applied to the pedal, the lever at the back pulls down the bottom part of the rod, and wherein when the pedal is released, the toilet seat slowly comes down due to the gravity and the counterweight on the extensions.
