Pressure (snap-in) flange for installing toilets

1. A pressure flange for installing toilets comprising:

a sealing ring disposed so as to make direct contact with a bottom of a toilet base;

a rigid main column configured to connect the toilet to a sewer line in a bathroom facility, the column having an upper tube section with a larger inner diameter section above a vertical tube section having a smaller inner diameter;

the column having an oval shaped collar at a top of the upper tube section, the oval shaped collar having oppositely extending ears;

a flex-line type pressure gasket disposed around at least the vertical tube section of the column, the pressure gasket comprising an accordion or corrugated-type of gasket that enables the pressure gasket to be fitted into the sewer line by applying downward pressure, wherein the pressure gasket further comprises a bottom lip that extends below and engages a bottom edge of the vertical tube section to prevent the pressure gasket from slipping when inserting the pressure flange into the sewer line; and

wherein the pressure flange can be installed without the use of tools by pushing the pressure flange down into the sewer line in the bathroom and tightening and connecting the pressure flange with anchor bolts and wing nuts to a toilet base.

2. The pressure flange for installing toilets as in claim 1 , wherein the upper tube section and vertical tube section are defined in a common tubular component, the oval shaped collar disposed above the tubular component.

3. The pressure flange for installing toilets as in claim 1 , wherein the sealing ring is made of rubber and is disposed in a ring-shaped cavity defined in a top of the oval shaped collar around an opening to the upper tube section.

4. The pressure flange for installing toilets as in claim 3 , further comprising curved stops located radially outward of the ring-shaped cavity such that the sealing ring seals against the toilet base without forcing or altering the structure of the pressure flange.

5. The pressure flange for installing toilets as in claim 1 , wherein the pressure flange is connected to the toilet, thereby making the toilet and the pressure flange become a single unit prior to pressing the pressure flange into the sewer line.

6. The pressure flange for installing toilets as in claim 1 , wherein the pressure gasket is preferably made of flexible corrugated or ribbed PVC, enabling it to be slid or inserted into the sewer line.

7. The pressure flange for installing toilets as in claim 1 , further comprising anchor bolt guides in the ears of the oval shaped collar.

8. The pressure flange for installing toilets as in claim 1 , wherein the main column is configured to be pressed into a rigid circular down pipe that accesses the sewer line.

9. The pressure flange for installing toilets as in claim 1 , further comprising a ring-shaped cavity defined in a top of the oval shaped collar around an opening to the upper tube section, and anchor bolt holes defined in the ears of the oval shaped collar radially outward of the ring-shaped cavity.

10. The pressure flange for installing toilets as in claim 1 , wherein the upper tube section has an inner diameter with sufficient space to accommodate toilets with varying water outlet diameters and water outlet heights in standard toilets.

11. The pressure flange for installing toilets as in claim 10 , wherein the upper tube section has an extension length between the oval shaped collar and the vertical tube section to accommodate toilets with varying water outlet depths.

12. A pressure flange for installing toilets comprising:

a sealing ring disposed so as to make direct contact with a bottom of toilet base;

a rigid main column configured to connect the toilet to a sewer line in a bathroom facility, the column having an upper tube section with a larger inner diameter section above a vertical tube section having a smaller inner diameter;

the column having an oval shaped collar at a top of the upper tube section, the oval shaped collar having oppositely extending ears;

a flex-line type pressure gasket disposed around at least the vertical tube section of the column, the pressure gasket comprising an accordion or corrugated-type of gasket that enables the pressure gasket to be fitted into the sewer line by applying downward pressure, wherein the pressure gasket further comprises a bottom lip that extends below and engages a bottom edge of the vertical tube section to prevent the pressure gasket from slipping when inserting the pressure flange into the sewer line;

wherein the pressure flange can be installed without the use of tools by pushing the pressure flange down into the sewer line in the bathroom and tightening and connecting the pressure flange with anchor bolts and win nuts to a toilet base; and

wherein the bottom lip of the pressure gasket extends radially into the vertical tube section and engages against an inner wall of the vertical tube section to further prevent the pressure gasket from slipping when inserting the pressure flange into the sewer line.

13. The pressure flange for installing toilets as in claim 12 , wherein the pressure gasket has a top end engaged against the upper vertical section of the main column which allows the exterior gasket to stay upright without folding and in the correct position when inserting it into the sewer line.
