A hinge assembly for adjustably mounting a toilet covering member to the rear of a toilet is disclosed. In one form, a hinge block has a compartment with serrations to adjustably receive a bushing with complementary serrations. A mounting bolt is placed through an opening in the hinge block and the bushing for engagement with a nut to secure the hinge assembly to the toilet. In one embodiment, the hinge block supports opposing hinge brackets for the toilet covering member with the hinge pin trapped by the mounting of one of the brackets. In an especially preferred form, the hinge assembly is employed with a cover and a toilet having matching curved front portions.

A one piece gasket for a toilet which eliminates the use of separate sealing washers and spacing devices is disclosed. The one piece gasket is formed with flange portions extending from a central sealing portion and has upstanding connectors (with fastener through bores) extending from the flange portions. The connectors can have an enlarged washer head and a bumper element. The washer heads provide an expansion fit into tank fastener holes for preliminary positioning of the gasket. In a preferred manner, the washer heads are of a frusto-conical configuration.

A hinge assembly for mounting a toilet covering member to the rear of a toilet so as to permit rotation of the covering about a hinge axis between an up and a down position is disclosed. In one form, a pair of hinge posts are mounted to the rear of the toilet which extend along a hinge axis. Each of a pair of hinge receiving elements are mounted to the toilet covering and has a bore which is alignable with one of the hinge post elements along the hinge axis. The hinge post elements have lugs axially spaced apart from stops and the bores in the hinge receiving elements are key-hole shaped to permit a key and slot type connection between the hinge post elements and the hinge receiving elements. The toiet covering member is captured on the toilet by axially inserting the hinge post elements into the corresponding bores and rotating the hinge post elements relative to the hinge receiving elements about the hinge axis to lock the elements together. In one embodiment, the hinge post elements extend in the same direction and are fixed. In another embodiment, they extend in opposite directions and are axially slidable relative to one another.

A flush valve connectable to a wall of a toilet tank is disclosed. In one embodiment, there is a non-circular outlet formed in the bottom wall of the tank. There is also a resilient seal bearing against an upper surface of the bottom wall, the seal surrounding the outlet and having a central bore aligned therewith. A flush valve is provided having a housing that extends through the seal bore and outlet. The housing also has an outwardly extending flange above the seal to trap the seal against the bottom wall, and a radially outwardly extending projection below the bottom wall. The housing is rotatable between a first position in which the projection can pass vertically through the outlet, and a second position where the projection can catch under the bottom wall. In another embodiment, there is a stop member formed on the outside of the housing below the resilient seal and above the projection, the stop member being suitable to interact with the periphery of the outlet to limit rotation of the housing relative to the outlet.
