Description:

FIELD OF THE INVENTION

[0001] The present invention generally relates to toilet bowls. More particularly, the invention relates to a toilet bowl with built in over flow protection.

BACKGROUND OF THE INVENTION

[0002] It has been highly desirable to create a toilet bowl that offers an overflow protection mechanism. While many inventions have been disclosed, all prior art inventions have at least one of two drawbacks, if not both. Prior art overflow protection devices are either expensive, very difficult to repair or maintain, or both. Early patents show flotation devices blocking off the supply, but utilize springs or other biasing means to locate them, and are not replaceable. Another prior art invention uses a flapper and float mechanism to stop the supply. The more recent prior art type overflow protection devices use electronics combined with mechanical devices to detect overflow conditions and stop the supply. No prior art inventions which applicant is aware of combine both ease of maintenance and minimal cost to manufacture.

SUMMARY OF THE INVENTION

[0003] In one aspect, the invention generally provides a toilet bowl with an overflow protection device disposed within. Such toilet bowl with the overflow protection device disposed within includes a first chamber having a predetermined shape. A first passageway is disposed in such toilet bowl and has a fluid connection to a source of fluid. A second passageway is disposed in such toilet bowl and has a fluid connection to a passageway for drainage of the contents of such bowl. A third passageway is disposed in such toilet bowl and has a fluid connection to such first passageway for allowing a fluid from such first passageway to pass to a first end of a predetermined plurality of flushing passageways disposed in the toilet bowl. A fourth passageway is disposed in such toilet bowl and has a first end in fluid communication with the third passageway, and a second end in fluid communication with such first chamber. A means is disposed within the fourth passageway for blocking a flow of fluid from such first passageway to such third passageway when the fluid level in such first chamber reaches a predetermined level.

OBJECTS OF THE INVENTION

[0004] A primary object of the present invention is to provide a toilet bowl with an overflow protection device disposed within that offers a means for blocking the supply of fluid when the fluid in the bowl reaches a predetermined level.

[0005] It is another object of the present invention to provide a toilet bowl with an overflow protection device disposed within that offers cost savings.

[0006] It is a further object of the present invention to provide a toilet bowl with an overflow protection device disposed within that offers ease of maintenance.

[0007] It is yet another object of the present invention to provide a toilet bowl with an overflow protection device disposed within that offers a minimum of moving parts.

[0008] It is still a further object of the present invention to provide a toilet bowl with an overflow protection device disposed within that offers over flow protection in which all devices are located internal to the bowl assembly.

[0009] In addition to the above-described objects and advantages of the toilet bowl with an overflow protection device disposed within, various other objects and advantages of the present invention will become more readily apparent to persons who are skilled in the same and related arts from the following more detailed description of the invention, particularly, when such description is taken in conjunction with the attached drawing figures and the appended claims.
