Abstract

Abstract A toilet has first and second hinges equidistantly spaced on opposite sides of a medial plane of the toilet with each hinge including a vertical hinge post having a horizontal pivot hole receiving a tubular pivot sleeve extending unitarily from a cover hinge body member with a pivot shaft of a seat hinge extending into the pivot sleeve for pivotal movement. The seat hinge and cover hinge each have outwardly extending spikes inserted in mounting bores in the seat and cover with the spikes having protrusions for retention in the mounting bores and being oriented at an acute angle to and flaring outwardly in reverse manner with respect to the medial plane with the post and hinge components being formed of fiberglass reinforced polypropylene.
