Abstract
The present invention provides for an improved toilet for flushing bodily waste materials. This toilet includes a secondary drain that communicates liquid that is backing up during a potential overflow situation into a conventional drainage sewer without any modification to that sewer.
Claims16
A toilet comprising:
- a waste-receiving basin;
- a primary drain having a primary drain inlet that is in fluid communication with said basin;
- a secondary drain having a secondary drain inlet that is in fluid communication with said basin and is located above said primary drain inlet;
- and
- a discharge collar having a contiguous outer wall sized to be received within a sewer discharge pipe, wherein said primary drain and said secondary drain independently run through said collar within said outer wall.
2 more elements
A toilet for flushing bodily waste into a sanitary discharge pipe, said toilet comprising:
- a structural body portion having a waste-receiving basin with a waste outlet formed in a lower end of said basin;
- a collar extending downwardly from an underside of the structural body portion, the collar comprising a tubular wall having inner and outer surfaces, wherein said inner surface defines a fluid passage and said outer surface is sized to be received within said sanitary discharge pipe;
- a primary drain interconnecting said basin waste outlet and said fluid passage;
- and
- a secondary drain having an inlet hole formed in said basin above said waste outlet, the secondary drain passing through the collar between the inner and outer surfaces.
2 more elements
A toilet for flushing bodily waste into a sanitary discharge pipe, comprising:
- a structural body portion having a waste-receiving basin with a waste outlet opening formed therein;
- a collar extending downwardly from an underside of the structural body portion, the collar comprising a tubular wall having a thickness between inner and outer surfaces, wherein said inner surface defines a fluid passage and said outer surface is sized to be received within said sanitary discharge pipe;
- a primary drain formed in the structural body portion having a primary drain inlet that is in fluid communication with said waste outlet opening, said primary drain terminating at and is in fluid communication with said fluid passage;
- and
- a secondary drain having water inlet means formed in said basin above said waste outlet, the secondary drain passing through the structural body portion and running through the thickness of the tubular wall adjacent to, but apart from, the fluid passage.
2 more elements
A toilet that is fluidly coupled to a sewer drainage pipe, said toilet comprising:
- a structural body portion having a waste-receiving basin with a basin outlet opening at a lower end thereof;
- a primary drain that is fluidly coupled to said basin at said basin outlet opening and which passes through said body portion and terminates at a primary drain passage;
- a tubular collar extending downwardly from a bottom end of said body portion, said collar having contiguous inner wall which defines said primary drain passage and a contiguous outer wall;
- and
- a secondary drain that fluidly couples said basin to said sewer drainage pipe, said secondary drain including:
- inlet means that is disposed within said basin above said basin outlet opening;
- and
- an overflow drain passageway which runs within and through said collar between said outer wall and said primary drain passage;
- 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 through said overflow drain tube and into said sewer drainage pipe.
6 more elements
A method of forming an anti-overflow feature in a toilet having a primary drain running from a waste-receiving basin to a sewer drainage pipe, comprising:
- extending a tubular collar from an underside of a structural body portion of said toilet, said tubular collar having an outer wall which is sized to be received within said drainage pipe and an inner wall which defines an outlet for said primary drain;
- and
- running a secondary drain from said basin and through said collar between said outer wall and said primary drain outlet, wherein waste water in said basin will rise within said basin and pass through said secondary drain into said sewer drainage pipe if said primary drain is blocked.
