Abstract
A drain assembly for a faucet includes a lift rod configured to be carried by the faucet and actuated relative to the faucet. A lever arm is configured to actuate a drain plug. A coupling device includes a first coupling portion coupled to the lift rod, a second coupling portion coupled to the lever arm, and a living hinge coupling the first coupling portion to the second coupling portion. The living hinge facilitates actuation of the lever arm and the drain plug upon actuation of the lift rod.

A drain assembly for a faucet, the drain assembly comprising:
- a lift rod configured to be carried by the faucet and actuated relative to the faucet;
- and
- a lever arm configured to actuate a drain plug;
- a coupling device comprising:
- a first coupling portion coupled to the lift rod;
- a second coupling portion coupled to the lever arm;
- and
- a living hinge coupling the first coupling portion to the second coupling portion and facilitating actuation of the lever arm and the drain plug upon actuation of the lift rod.
A drain assembly for a faucet, the drain assembly comprising:
- a lift rod configured to be carried by the faucet and actuated relative to the faucet;
- and
- a lever arm configured to actuate a drain plug;
- a coupling device comprising:
- a first coupling portion coupled to the lift rod, the first coupling portion comprising:
- a collet disposed about the lift rod, the collet comprising a concave tapering surface and a first threaded surface;
- a retainer comprising a conical portion receiving the lift rod and including a convex tapering surface, the retainer further comprising a second threaded surface, the second threaded surface being engagable with the first threaded surface of the collet to cause the convex tapering surface to engage the concave tapering surface of the collet to urge the conical portion to engage the lift rod and thereby secure the retainer to the lift rod;
- a second coupling portion coupled to the lever arm;
- and
- a leg portion coupling the first coupling portion to the second coupling portion and facilitating actuation of the lever arm and the drain plug upon actuation of the lift rod.
