Patent ID: 7757312

Claim:
An anti-overflow bathroom fixture that is fluidly coupled to a sewer drainage pipe, said fixture comprising: a structural body portion having a waste receiving basin that includes an upper rim and which holds an amount of water at a certain water level; a primary drain that is fluidly coupled to said basin and which terminates at a drain passage in a tubular collar extending downwardly from a bottom end of said body portion, said collar having an inner surface which defines said drain passage, a cylindrical outer surface and a thickness between said outer surface and said inner surface and is fluidly coupled to said sewer drainage pipe; and a secondary drain that fluidly couples said basin to said sewer drainage pipe, said secondary drain including: inlet means that are disposed within said basin between said rim and said certain water level; an overflow drain tube that is approximately one half inch in inside diameter and is in fluid communication with said inlet means; and a discharge port that is in fluid communication with said overflow drain tube and is disposed within and runs through said thickness of said collar; wherein said collar projects downwardly into said sewer drainage pipe such that a lower end of said outer surface is telescopically received within said sewer drainage pipe when said collar is fluidly coupled to said sewer drainage pipe, whereby said inlet means permits rising waste water to flow from said basin into said overflow drain tube and out of said discharge port to said sewer drainage pipe.
