Abstract
Abstract A toilet seat and cover assembly wherein the pivot axis in the seat is a considerably greater distance above the seat bottom than from the plane of the seat back edge, so that the back edge of the seat will be spaced a substantial distance above the top surface of a toilet bowl upon which the seat is mounted, when the seat is swung about its pivot to an upright position. The seat, cover and hinge posts are pivotally connected by removable hinge pins having yieldable means to prevent accidental displacement.
