Abstract: A toilet seat and lid, each comprising a rigid insert injection molded of thermoplastic material. Each insert is then over-molded by injection molding with a thermoplastic elastomeric material which provides the outer surface of the seat and lid. The inserts are dimensioned with respect to their over-molded surfaces to be smaller than the finished seat and lid and are designed to give maximum strength to the seat and lid. Each insert is shaped to promote the flow of the over-mold material and to minimize shrinking, swelling or distortion of the insert. The elastomeric material is preferably chemically compatible with the inserts to allow a chemical as well as a mechanical bond to take place. The over-molded material provides the desired soft, non-slip, warm to the touch outer characteristics of the seat and lid.

Abstract: A toilet hinge for hingedly mounting a seat and/or cover on a toilet bowl comprises a hinge part which includes resiliently yieldable fingers for cooperative engagement with the hinge pin. The hinge part contains a circular aperture having a circumferential extent greater than 180.degree. but less than 360.degree., with the resiliently yieldable fingers extending from the aperture at a circumferential opening in the aperture. The resiliently yieldable fingers define a throat within which the hinge pin is received in response to downward loading applied to the seat and/or cover. The resilient yielding of the fingers allows the seat and/or cover to assume full support on the bowl rim so that the undesired stress levels in the parts, including the hinges, are avoided. When the downward load is removed, the resiliently yieldable fingers urge the hinge pin back into the aperture, thereby slightly elevating the rear of the seat and/or cover.
