Abstract

An inflatable pool is includes a floor drain having a drainage conduit and two sealing plug. The drainage conduit includes a midsection pipe having an oblong cross section, an inlet cap having a truncated profile, and an outlet cap that transitions from the oblong profile of the midsection to a cylindrical profile.

First claim

What is claimed:

1. An inflatable pool comprising: a first internal wall; a second external wall positioned outside of the first internal wall; a floor that cooperates with the internal wall to define a water cavity; and a floor drain in communication with the water cavity, the floor drain including a drainage conduit having an inlet end positioned in the floor in a location spaced apart from and horizontally interior of the first internal wall and an outlet end positioned horizontally external of the first internal wall, a first sealing plug removably coupled to the inlet end to block drainage of water from the water cavity when coupled to the inlet end and permit drainage of water from the water cavity when removed from the inlet end, and; wherein the drainage conduit includes a midsection pipe positioned between the inlet end and the outlet end, the midsection pipe has a flat portion extending in a direction between the inlet and outlet ends and a rounded portion positioned adjacent to the flat portion extending in a direction between the inlet and outlet ends.

2. The inflatable pool of claim 1 , wherein the inlet end includes a soft portion and a hard portion that is harder than the soft portion, the soft portion being sealingly coupled to the floor and configured to receive the first sealing plug.

3. The inflatable pool of claim 1 , wherein the inlet end includes a conical portion having a wide end and a narrow end positioned between the first sealing plug and the wide end of the conical portion.

4. The inflatable pool of claim 3 , wherein the wide end of the conical portion includes a substantially circular base and a plurality ribs extending radially inwardly from the substantially circular base.

5. The inflatable pool of claim 3 , wherein the drainage conduit includes a longitudinal axis, the wide end of the conical portion includes a substantially circular base and a plurality of ribs that extend in a direction perpendicular to the longitudinal axis of the drainage conduit.

6. The inflatable pool of claim 1 , wherein the flat portion of the midsection pipe is substantially parallel to the floor of the inflatable pool.

7. The inflatable pool of claim 1 , wherein the drainage conduit includes an inlet cap positioned over an inlet end of the midsection pipe and an outlet cap positioned over an outlet end of the midsection pipe.

8. The inflatable pool of claim 7 , wherein the outlet cap transitions from an oblong profile covering the midsection pipe to a cylindrical profile.

9. An inflatable pool comprising: a first internal wall; a second external wall positioned outside of the first internal wall; a floor that cooperates with the internal wall to define a water cavity; and a floor drain in communication with the water cavity, the floor drain including a drainage conduit having an inlet end positioned in the floor in a location spaced apart from and horizontally interior of the first internal wall, an outlet end positioned horizontally external of the first internal wall, and a midsection pipe having at least a portion inside of the second external wall and outside of the first internal wall, the portion of the midsection pipe having an oblong profile having a major axis and a minor axis, the major axis extending in a direction substantially parallel to the floor of the inflatable pool, and the minor axis extending in a direction substantially perpendicular to the floor of the inflatable pool; wherein the midsection pipe includes a flat portion extending in the longitudinal direction and a rounded portion extending in the longitudinal direction, the minor axis extends through the flat portion and the major axis extends through the rounded portion.

10. The inflatable pool of claim 9 , wherein the floor drain further includes an inlet cap having a truncated conical profile and an outlet cap transitioning from an oblong profile positioned over a portion of the midsection pipe to a cylindrical profile.

11. The inflatable pool of claim 10 , wherein the inlet cap includes an oblong profile that transitions into the truncated conical profile.

12. The inflatable pool of claim 11 , wherein the inlet cap further includes a cylindrical profile that transitions into the truncated conical profile.

13. The inflatable pool of claim 12 , wherein the cylindrical profile of the inlet cap has a central axis that is substantially parallel to the first internal wall and the oblong profile of the inlet cap has a major axis and a minor axis, the minor axis is substantially parallel to the central axis of the cylindrical profile of the inlet cap and the major axis is substantially perpendicular to the central axis of the cylindrical profile of the inlet cap.

14. The inflatable pool of claim 10 , wherein the oblong profile of the midsection pipe includes a central longitudinal axis and the cylindrical profile of the outlet cap includes a central longitudinal axis, the central longitudinal axis of the oblong profile is vertically positioned between the central axis of the cylindrical profile and a bottom of the inflatable pool.

15. The inflatable pool of claim 10 , wherein the first internal wall defines a first substantially cylindrical projection and the second external wall defines a second substantially cylindrical projection positioned outside the first substantially cylindrical projection, the inlet cap is entirely positioned within the first substantially cylindrical projection, and the outlet cap is positioned at least partially within the second substantially cylindrical projection.

16. An inflatable pool comprising: a first internal wall; a second external wall positioned outside of the first internal wall; a floor that cooperates with the internal wall to define a water cavity; and a floor drain in communication with the water cavity, the floor drain including a drainage conduit having an inlet end and an outlet end, the inlet end being positioned in the floor in a location spaced apart from and horizontally interior of the first internal wall, and the outlet end being positioned horizontally external of the first internal wall, an inlet cap positioned over the inlet end, an outlet cap positioned over the outlet end, and a plug, the inlet cap having a truncated cone-shaped body portion having a substantially circular base and a plug-receiving portion having an opening sized to receive the plug to block the passage of water from the water cavity through the drainage conduit, the truncated cone-shaped body portion expanding outwardly from the plug-receiving portion to the substantially circular base; wherein the inlet end includes a conical portion having a wide end and a narrow end positioned between the first sealing plug and the wide end of the conical portion.

17. The inflatable pool of claim 16 , wherein the inlet cap further includes a plurality of radially extending ribs extending radially inwardly from the truncated cone-shaped body portion.

18. The inflatable pool of claim 17 , wherein the drainage conduit has a longitudinal axis and the inlet cap further includes a plurality of ribs extending perpendicular to the longitudinal axis.

19. The inflatable pool of claim 16 , wherein the floor includes an upper layer and a lower layer, perimeter portions of the upper layer and lower layer being joined and interior portions of the upper and lower layers being spaced apart, the opening of the plug-receiving portion being positioned between an adjacent portion of the first internal wall and an adjacent portion of the joined perimeter portions of the upper and lower layers of t
