Overflow cap and assembly
An overflow assembly including an overflow cap and a locking ring is described that allows liquid (e.g., water) being received or collected in a plumbing fixture (e.g., a bathtub) to flow into an overflow pipe in an effective, aesthetically pleasing manner using components that are easier to install than some conventional solutions. The locking ring has a threaded inner surface that is designed to be threaded onto an externally threaded end of the overflow pipe that is extended through a wall of the plumbing fixture to secure the overflow pipe with respect to the wall. The overflow cap may then be pressed onto the externally threaded end of the overflow pipe, such that it engages the externally threaded end via engagement tabs. The overflow cap can be removed from the end of the overflow pipe by rotating the cap to unthread it from the threaded end of the overflow pipe.
1. An overflow assembly configured to engage an overflow pipe, the overflow assembly comprising:
an overflow cap including:
a main portion defining an outer surface and an inner surface, wherein the outer surface is configured to be visible to a user in an installed position in which the overflow cap is engaged with an overflow pipe;
a peripheral extension extending transversely from a periphery of the main portion and configured to extend towards a wall through which the overflow pipe is engaged, wherein the peripheral extension defines at least one opening configured to be in fluid communication with the overflow pipe for receiving overflow liquid therethrough; and
a plurality of discrete engagement tabs, each engagement tab extending from the inner surface of the main portion and away from the inner and outer surfaces, wherein each engagement tab is spaced inwardly from the peripheral extension and is substantially parallel to an inner surface thereof; and
a locking ring comprising a threaded inner surface configured to be threaded onto an externally threaded end of the overflow pipe, wherein the locking ring is configured to secure the overflow pipe with respect to the wall,
wherein the overflow cap is configured to be pressed onto the externally threaded end of the overflow pipe following engagement of the locking ring with the overflow pipe, wherein the overflow cap is configured to engage the externally threaded end of the overflow pipe via the plurality of engagement tabs, wherein the inner diameter of the peripheral extension is larger than the outer diameter of the locking ring, and wherein the peripheral extension of the overflow cap does not contact the locking ring.
2. The overflow assembly of claim 1 , wherein the peripheral extension defines at least two openings configured to be in fluid communication with the overflow pipe for receiving overflow liquid therethrough.
3. The overflow assembly of claim 1 , wherein the overflow cap further comprises at least one spacer extending from the inner surface of the main portion and away from the inner and outer surfaces, wherein the spacer is configured to abut an edge of the externally threaded end of the overflow pipe in the installed position so as to maintain a space between the inner surface of the main portion and the edge of the externally threaded end of the overflow pipe.
4. The overflow assembly of claim 1 , wherein the main portion further defines at least one slot extending between the inner and outer surfaces of the main portion, wherein the at least one slot is in fluid communication with the overflow pipe.
5. The overflow assembly of claim 1 , wherein the locking ring comprises an outer surface defining a plurality of grooves configured to provide a gripping surface to the user for installing the locking ring onto the overflow pipe.
6. The overflow assembly of claim 1 , wherein each engagement tab of the overflow cap defines an outward-facing surface facing the peripheral extension and an inward-facing surface facing away from the peripheral extension, wherein the inward-facing surface defines a plurality of teeth configured to slidingly engage the externally threaded end of the overflow pipe.
7. The overflow assembly of claim 6 , wherein the overflow cap is configured to be disengaged from the externally threaded end of the overflow pipe via rotation of the overflow cap with respect to the overflow pipe.
8. An overflow cap configured to engage an overflow pipe that includes a locking ring attached thereto, the overflow cap comprising:
a main portion defining an outer surface and an inner surface, wherein the outer surface is configured to be visible to a user in an installed position in which the overflow cap is engaged with an overflow pipe;
a peripheral extension extending transversely from a periphery of the main portion and configured to extend towards a wall through which the overflow pipe is engaged, wherein the peripheral extension defines at least one opening configured to be in fluid communication with the overflow pipe for receiving overflow liquid therethrough; and
a plurality of discrete engagement tabs, each engagement tab extending from the inner surface of the main portion and away from the inner and outer surfaces, wherein each engagement tab is spaced inwardly from the peripheral extension and is substantially parallel to an inner surface thereof,
wherein the overflow cap is configured to be pressed onto an externally threaded end of the overflow pipe and is configured to engage the threaded end of the overflow pipe via the plurality of engagement tabs, wherein the inner diameter of the peripheral extension is larger than the outer diameter of the locking ring, and wherein the peripheral extension does not contact the locking ring.
9. The overflow cap of claim 8 , wherein the peripheral extension defines at least two openings configured to be in fluid communication with the overflow pipe for receiving overflow liquid therethrough.
10. The overflow cap of claim 8 further comprising at least one spacer extending from the inner surface of the main portion and away from the inner and outer surfaces, wherein the spacer is configured to abut an edge of the threaded end of the overflow pipe in the installed position so as to maintain a space between the inner surface of the main portion and the edge of the threaded end of the overflow pipe.
11. The overflow cap of claim 8 , wherein the main portion further defines at least one slot extending between the inner and outer surfaces of the main portion in fluid communication with the overflow pipe.
12. The overflow cap of claim 8 , wherein each engagement tab defines an outward-facing surface facing the peripheral extension and an inward-facing surface facing away from the peripheral extension, wherein the inward-facing surface defines a plurality of teeth configured to slidingly engage the threaded end of the overflow pipe.
13. The overflow cap of claim 12 , wherein the overflow cap is configured to be disengaged from the threaded end of the overflow pipe via rotation of the overflow cap with respect to the overflow pipe.
