ABSTRACT:
A hinge mechanism for a toilet bowl seat or seat lid has improved control of rotation due to torque exerted by a cam member working with a compression spring and slider, such that the torque varies depending on the angle of the seat or seat lid to the plane of the toilet bowl. The slider and cam member are mounted on a shaft having an axially directed oval hole in which a complementary shaped hinge pin is received to connect the seat and the seat lid to the mechanism. A stop mechanism prevents the shaft from turning beyond a predetermined angle.
