Abstract

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.

Dependent claims

A toilet covering hinge assembly, comprising:

a pair of spaced apart hinge receiving elements, each said hinge receiving element having a bore which is alignable with a hinge axis;
a pair of hinge post elements, one corresponding to each hinge receiving element, each of said hinge post elements being axially insertable into the bore of the corresponding hinge receiving element;
two of said elements being suitable to be connected to the rearward portion of a toilet, and the other two of said elements being suitable to be connected to the rearward portion of a first covering member;
a carriage;
at least one of said elements being fixed to the carriage, said carriage being slidable along the hinge axis to restrain said one of said elements against rotation;
and
said elements and bores being fashioned so as to permit a key-in-slot type connection between each hinge post element and the corresponding hinge receiving element to capture the first covering member on the toilet and to capture the slidable element and carriage axially by inserting the hinge post elements into the corresponding hinge receiving elements and rotating the covering member about the hinge axis, thereby locking the hinge post elements and the hinge receiving elements together;
wherein the carriage is slidable along the hinge axis to assemble or disassemble the key in slot connection associated with the carriage only when the covering member is in an assembly position in which the key and slot associated with the carriage are in angular registration with one another.
