Pop-up drain assembly
First Claim
1. A drain stopper, comprising:
- an elongated body having a longitudinal axis, the body comprising two or more longitudinal fins for centering the body in a drain pipe, wherein the fins project radially and define an outermost circumference of the body;
a cap on one end of the body for providing a seal;
a magnet holder extending longitudinally from one of the fins away from the cap end; and
a magnet or a magnetic material received in the magnet holder, wherein the magnet holder, the magnet or the magnetic material has an outer surface approximately and substantially aligned with the outermost circumference of the body, and wherein the magnet or magnetic material is elongated and has a longitudinal axis that is radially offset from and substantially parallel to the longitudinal axis of the body.

Abstract
A pop-up drain assembly for a sink has drain piping, a stopper in the drain piping and a pivot rod for opening and closing the stopper, which tends not to clog because the pivot rod is not within a fluid flow path. In one embodiment the stopper has flow diverter plates that channel fluid flowing through the drain piping away from the pivot rod so that hair, waste and debris does not catch on and accumulate on the pivot rod. In another embodiment the stopper and the pivot rod are engaged through magnetic coupling, and the pivot rod does not protrude into the fluid flow path. The stopper is preferably variable in length for adjustment to fit different distances from the pivot rod to the top of the drain piping.

4. A drain stopper operable with a pop-up drain assembly having a drain pipe that has a pivot rod port, wherein the drain stopper is in a vertical position while in operation, the drain stopper comprising:
-
a body that has a length, a longitudinal axis, an upper end, a lower end, a magnet holder and a magnet or a magnetic material received in or on the magnet holder, wherein the magnet holder extends toward or to the lower end of the body, wherein the magnet holder or the magnet or magnetic material provides a longitudinal outermost side portion of the body that is sized and designed to place the magnet or magnetic material adjacent to the pivot rod port, wherein the magnet or magnetic material is elongated and has a longitudinal axis, and wherein the longitudinal axis of the magnet or magnetic material is oriented vertically while in operation and is offset radially from the longitudinal axis of the body; and a cap received on the upper end of the body. - View Dependent Claims (5)
