Abstract
A molded seat assembly comprises an insert having an upper and a lower surface, a peripheral edge, and a ridge disposed adjacent to the peripheral edge. A seat portion comprised of a plastic material is molded directly to the insert whereby the plastic material contacts the peripheral edge, the ridge, the upper surface melts or softens the peripheral edge, the ridge and the upper surface forming both a cohesive bond and a locking engagement between the seat portion and the insert.
Claims26
A molded seat assembly comprising:
- an insert having an upper and a lower surface, a peripheral edge, and a ridge disposed adjacent to said peripheral edge;
- and
- a seat portion comprised of a plastic material molded directly to said insert whereby said ridge is adapted to prevent the flow of the plastic material beyond said ridge.
A method of making a molded seat assembly, said method comprising the steps of:
- a) disposing an insert into an orifice of a mold, the mold having an inner surface defining an outer surface of a seat body, wherein said insert includes a peripheral edge which is adapted to be partially embedded in the outer surface of the seat body and wherein said insert includes a ridge disposed adjacent to said peripheral edge;
- b) disposing a parison of plastic material into said mold;
- and
- c) molding said plastic material by blowing pressurized gas into said parison thereby simultaneously forcing said material against said mold inner surface and said insert, thereby forming said seat body, said plastic material engulfing said peripheral edge and forming a locking engagement between said seat body and said peripheral edge, said ridge limiting the flow of plastic material to a area adjacent to said peripheral edge.
