Hinge pin for lavatory seat and/or lid

A hinge pin for pivotally mounting at least one of a toilet seat and a toilet lid to a toilet or surrounding structure, comprising:

• a first hinge pin component having a cylindrical outer end, a semicylindrical inner end with a flat joining surface and a shoulder between the outer end and the inner end;
• a second hinge pin component having a cylindrical outer end, a semicylindrical inner end with a flat joining surface and a shoulder between the outer end and the inner end;
• a semicylindrical linking member with a flat linking surface dimensioned to link the first hinge pin component and the second hinge component when they are axially aligned with their inner ends facing each other and the linking surface in contact with each joining surface, wherein the assembled linking member and first and second hinge components define a center section of the hinge pin having a circular cross section;
• and
• a plurality of fasteners configured to couple the linking member to each of the first and second hinge pin components.

A method of assembling at least one of a toilet seat and a toilet lid for pivotable movement relative to a toilet or surrounding structure, comprising:

• inserting a first hinge pin component having a cylindrical end from an inboard side distally through a first opening in at least one of the toilet seat and toilet lid;
• inserting a second hinge pin component having a cylindrical end from an inboard side distally through a second opening in at least one of the toilet seat and toilet lid, the second opening being opposite and axially aligned with the first opening;
• positioning a linking member to overlap each of the first hinge pin component and the second hinge pin component;
• and
• coupling the linking member to the first hinge pin component and the second hinge pin component to form a one-piece hinge pin assembly.
