Sink and drain for sink
Sinks and drains for sinks permitting the attachment of the drain to the sink such that the drain is substantially disposed below the top surface of the sink basin, and such that there is no discernable separation between the base of the sink basin and the drain when viewed from above the sink. A method of making a sink such that there is no discernable separation between the base of the sink basin and the drain when viewed from above the sink.
1. A sink comprising:
a sink basin having a sidewall and a base in a bottom portion thereof, the base including a drain opening;
a first drain entry portion integrally formed from the base and extending from the bottom portion at the drain opening;
a second drain entry portion including a first end portion with a radially outwardly extending flange configured to connect to the base at the first drain entry portion, and
a second end portion opposite the first end portion;
a bracket including a lip configured to engage the flange; and
a fastener attaching the bracket to the base to thereby hold the first end of the second drain entry portion to the first drain entry portion with the lip engaged with the flange.
2. The sink of claim 1 , wherein the bracket is ring-shaped and is sized and shaped to surround the first end portion.
3. The sink of claim 2 , wherein the lip is circular and defines an annular space with the bottom portion that is sized and shaped to receive the flange.
4. The sink of claim 1 , wherein the fastener includes a threaded fastener.
5. The sink of claim 4 , wherein the threaded fastener includes one of a screw and a bolt.
6. The sink of claim 5 , further comprising an anchor disposed within a bore of the base, wherein the fastener is threadably received by the anchor to attach the bracket to the base.
7. The sink of claim 6 , wherein the anchor is one or more of press-fit, glued, and threaded into the base.
8. The sink of claim 1 , further comprising a gasket disposed between the flange and the base.
9. The sink of claim 1 , further comprising:
a flange plate having an inner edge portion and an outer edge portion, the inner edge portion forming a drain opening that permits water from the second drain entry portion to flow through the flange plate, the outer edge portion extending to the second drain entry portion;
a first seal formed at a first junction of the outer edge portion of the flange plate and the second drain entry portion;
a drain pipe fluidly connected to the inner edge portion of the flange plate around the drain opening;
a second seal formed at a second junction of the drain pipe and the inner edge portion of the flange plate;
a strainer; and
a removable drain basket that includes a stopper, the stopper being selectively placeable between a lowered position, in which the stopper covers the strainer to plug the drain opening, and a raised position, in which water from the second drain entry portion flows around the stopper and through the drain opening.
