Patent ID: 7331067

Claim:
A toilet seat lifting and lowering apparatus for lifting and lowering a toilet seat of a toilet, comprising: A) a foot pedal; B) a torque transfer mechanism comprising a first part and a second part; C) a first lever arm having first and second ends, said first end rigidly attached to said first part of said torque transfer mechanism and at said second end to said foot pedal; D) a second lever arm having first and second ends, said first end of said second lever arm rigidly attached to said second part of said torque transfer mechanism and slidingly attached at said second end of said second lever arm to said toilet seat; and E) said first and second parts of said torque transfer mechanism are in contact with one another; characterized in that when said toilet seat is in a horizontal position a downward force on said foot pedal produces a rotation of said first part of said torque transfer mechanism which by its engagement with said second part of said torque transfer mechanism produces an opposite rotation of said second part of said torque transfer mechanism causing said toilet seat to lift to a raised position, and wherein when said toilet seat is in its raised position an upward force applied under said foot pedal produces a rotation of said first part of said torque transfer mechanism which produces an opposite rotation of said second part of said torque transfer mechanism causing said second lever arm to move said toilet seat to its horizontal position, said first and second parts of said torque transfer mechanism comprising first and second cams.
