Abstract
A mounting assembly to couple a water tank to a water closet is disclosed. The mounting assembly includes a threaded bolt, tubular elastomeric seal member and fastening means. The elastomeric member has centering ribs formed around its outer surface, a flanged head at one end and the other end is bifurcated. When the bolt is inserted therethrough, the elastomeric member expands in the tank mounting opening and the bifurcated end diverges to form a pair of latching tabs to prevent removal of the elastomeric seal member and bolt from the tank mounting opening.
Claims2
A mounting assembly adapted to couple a water tank to a water closet, said assembly comprising:
- an elastomeric seal member having a tubular body, one end of which is formed having a flanged head, the diameter of which is greater than the diameter of a tank mounting opening formed in the base of said water tank, and the other end is bifurcated, said bifurcated end portions having slots formed therebetween that extend longitudinally from said associated end to the midportion of said tubular body, said tubular body having an axial passage formed therethrough, and at least one longitudinal extending centering rib integrally formed on its external surface is positioned between said flanged head and one of said bifurcated end slots;
- a bolt having an elongated shank which is threaded at one end and a flanged head formed at the other end is telescopically positioned in said passageway of elastomeric member;
- and
- fastening means to threadedly connect said threaded end of said bolt when said tank and water closet are coupled together and to press said bifurcated end portions between the water tank and the water closet in order to form lateral stops that prevent said bolt and said seal member from removal from the water tank.
