Abstract

A drain assembly for use with a faucet including a lift rod, a lever arm, and a coupler operably coupling the lift rod and the lever arm.

Claims

1. A drain assembly for use with a faucet, the drain assembly comprising:

a lift rod;

a lever arm; and

a coupler including a center portion, an upper leg connected to the center portion and extending laterally in a first direction, a lower leg connected to the center portion below the upper leg and extending laterally in the first direction, the upper leg including a first opening and the lower leg including a second opening alignable with the first opening for receiving the lift rod, the upper leg and the lower leg being biased away from each other for frictionally engaging the lift rod, the coupler further including a receiver extending laterally in the first direction from the center portion and receiving the lever arm, the receiver including a first leg, a second leg, a tab coupled to the first leg and the second leg, and an opening defined between the first leg, the second leg, and the tab, such that the lever arm is received within the opening and is positioned vertically intermediate the upper leg and the lower leg of the coupler and horizontally intermediate the center portion of the coupler and the lift rod.

2. The drain assembly of claim 1, wherein the receiver, the upper leg, and the lower leg are integral with the center portion of the coupler.

3. The drain assembly of claim 2, wherein the coupler is formed of spring biased steel.

4. The drain assembly of claim 1, wherein the receiver extends laterally in the same direction as the upper and lower legs.

5. The drain assembly of claim 1, wherein the upper leg is angled upwardly relative to the center portion of the body, and the lower leg is angled downwardly relative to the center portion of the body.

6. The drain assembly of claim 4, wherein the upper leg and the lower leg are angled from the center portion by approximately 45 degrees.

7. The drain assembly of claim 1, wherein the lift rod includes a lower member, an upper member, and a lift rod coupler coupled to the upper member and the lower member.

8. The drain assembly of claim 1, further comprising a drain plug operably coupled to the lever arm such that movement of the lift rod causes corresponding movement of the drain plug.

9. A drain assembly for use with a faucet, the drain assembly comprising:

a lift rod defining a first axis;

a lever arm defining a second axis; and

a coupler including a center portion extending substantially parallel to the first axis, an upper leg connected to the center portion and extending laterally in a first direction and longitudinally up, and a lower leg extending laterally in the first direction and longitudinally down, the upper leg and the lower leg being biased away from each other, the upper leg including a first opening having an outer edge and the lower leg including a second opening having an outer edge and alignable with the first opening for receiving the lift rod, the bias of the upper leg and the lower leg causing the outer edges of the first opening and the second opening to frictionally engage the lift rod, the coupler further including a receiver extending laterally in the first direction from the center portion and including a first leg spaced apart from a second leg to define an opening to receive the lever arm such that the second axis is substantially perpendicular to the first axis and the lever arm is horizontally intermediate the center portion of the coupler and the lift rod.

10. The drain assembly of claim 9, wherein the coupler is formed of spring biased steel.

11. The drain assembly of claim 9, wherein the receiver, the upper leg, and the lower leg are integral with the center portion of the coupler.

12. The drain assembly of claim 9, wherein the lift rod includes a lower member, an upper member, and a lift rod coupler coupled to the upper member and the lower member.

13. The drain assembly of claim 9, further comprising a drain plug operably coupled to the lever arm such that movement of the lift rod causes corresponding movement of the drain plug.

14. A coupler for a drain assembly, the coupler comprising:

a center portion;

an upper leg connected to the center portion and extending laterally in a first direction, the upper leg including a first opening;

a lower leg extending laterally in the first direction, the upper leg and the lower leg being biased away from each other, the lower leg including a second opening alignable with the first opening to receive a lift rod; and

a receiver extending laterally in the first direction from the center portion and including a first leg spaced apart from a second leg to define an opening configured to receive a lever arm, the lever arm configured to be positioned horizontally intermediate the center portion and the lift rod,

wherein the coupler includes a first state and a second state, the upper leg and the lower leg being biased away from each other in the first state, and the upper leg and the lower leg being pinched toward each other to resist the biasing away from each other in the second state such that the first opening is aligned with the second opening to receive the lift rod in the second state and frictionally engage the lift rod in the first state.

15. The coupler of claim 14, wherein the receiver, the upper leg, and the lower leg are integral with the center portion.

16. The coupler of claim 15, wherein the center portion, the receiver, the upper leg, and the lower leg are formed of spring biased steel.

17. The coupler of claim 14, wherein the upper leg and the lower leg are angled from the center portion by approximately 45 degrees.

18. A method of connecting a drain assembly comprising the steps of:

providing a coupler including a center portion and opposing upper and lower legs connected to the center portion, the upper and lower legs having a bias away from each other;

placing a lever arm within a receiver of the coupler, the receiver including a first leg, a second leg, a tab coupled to the first leg and the second leg, and an opening defined between the first leg, the second leg, and the tab, such that the lever arm is received within the opening and is positioned vertically intermediate the opposing upper and lower legs of the coupler and horizontally intermediate the center portion of the coupler and a lift rod;

pinching the opposing upper and lower legs of the coupler to oppose the bias thereby aligning openings formed within the legs;

inserting the lift rod within the openings of the legs of the coupler; and

releasing the opposing legs of the coupler to allow the bias of the legs to frictionally engage the lift rod.

19. The method of claim 18, further comprising the step of slidably adjusting the coupler along the lift rod by pinching the opposing legs, thereby adjusting the position of the lever arm.
