a bolt extending through the mounting member and configured to extend through an opening in the toilet bowl for securing the mounting member to the toilet bowl, the bolt including a head that is seated within the mounting member, the bolt engaging an inner surface of the mounting member to prevent rotation of the bolt relative to the mounting member; and
a nut threadable onto the bolt to secure the hinge post to the toilet bowl, the nut having a first segment threadable onto the bolt, a second segment, and a shear segment connecting the first and second segments, the shear segment having a lower torque resistance than the first and second segments such that the shear segment breaks when torque applied to the second segment reaches a predetermined amount.
7. The hinge assembly of claim 6 , wherein the bolt includes a splined section that engages the inner surface of the mounting member to prevent rotation of the bolt relative to the mounting member.
8. The hinge assembly of claim 6 , wherein the mounting member is molded over the bolt.
9. The hinge assembly of claim 6 , wherein the mounting member is formed of plastic and the bolt is formed of metal.
10. The hinge assembly of claim 6 , further comprising a bushing configured to extend into and conform to the shape of the opening in the toilet bowl, and wherein the bolt extends through the bushing.
11. The hinge assembly of claim 10 , wherein the bushing and the mounting member are formed as a single piece.
12. A hinge assembly for a toilet seat, the hinge assembly comprising:
a hinge post for pivotally supporting the toilet seat on a toilet bowl;
a bushing configured to extend into an opening in the toilet bowl, the bushing including a plurality of projections extending radially outward therefrom, the plurality of projections configured to deform as the bushing is inserted into the opening in the toilet bowl to conform to the shape of the opening;
a bolt connectable to the hinge post for securing the hinge post to the toilet bowl, the bolt extending through the bushing and being configured to extend through the opening in the toilet bowl; and
a nut threadable onto the bolt to secure the hinge post to the toilet bowl, the nut having a first segment threadable onto the bolt, a second segment, and a shear segment connecting the first and second segments, the shear segment having a lower torque resistance than the first and second segments such that the shear segment breaks when torque applied to the second segment reaches a predetermined amount;
wherein the bolt is connectable to the hinge post by a quick release mechanism.
13. The hinge assembly of claim 12 , wherein the plurality of projections includes four projections spaced approximately ninety degrees apart around the bushing.
14. The hinge assembly of claim 12 , wherein the quick release mechanism includes a mounting member connected to the bolt and a mechanism for releasably connecting the hinge post to the mounting member, and wherein the bushing is part of the mounting member.
15. The hinge assembly of claim 14 , wherein the bolt extends through an aperture of the mounting member such that a head of the bolt is seated in the mounting member.
16. The hinge assembly of claim 15 , wherein the mounting member includes a splined inner surface that engages a splined section of the bolt to prevent rotation of the bolt relative to the mounting member.
17. The hinge assembly of claim 14 , wherein one of the hinge post and the mounting member includes a movable projection, the other of the hinge post and the mounting member defines a recess, and the mechanism for releasably connecting the hinge post to the mounting member includes a locking member that is movable relative to the hinge post between a locked position and an unlocked position, and wherein the locking member holds the movable projection in the recess when in the locked position to secure the hinge post to the mounting member.
18. A toilet comprising:
a toilet bowl having an opening;
a toilet seat;
a hinge post for pivotally supporting the toilet seat on the toilet bowl, the hinge post including a bushing that extends into the opening in the toilet bowl, the bushing including a plurality of projections extending radially outward therefrom, at least some of the projections being deformed by insertion of the bushing into the opening in the toilet bowl so that the bushing conforms to the shape of the opening;
a bolt connectable to the hinge post for securing the hinge post to the toilet bowl, the bolt extending through the bushing and the opening in the toilet bowl; and
a nut threadable onto the bolt to secure the hinge post to the toilet bowl, the nut having a first segment threadable onto the bolt, a second segment, and a shear segment connecting the first and second segments, the shear segment having a lower torque resistance than the first and second segments such that the shear segment breaks when torque applied to the second segment reaches a predetermined amount;
