Abstract

Disclosed is a friction ring including a body and a contact member. The body is configured to couple the friction ring to at least one of a faucet assembly or a faucet valve assembly. The contact member is disposed on the body. The contact member is configured to slidably engage with a valve stem of the faucet valve assembly. The contact member is further configured to press against the valve stem to increase a frictional force between the contact member and the valve stem over a full range of movement of the valve stem.

First claim

What is claimed is:

1. An assembly, comprising:
a friction ring including:
a body configured to couple the friction ring to at least one of a faucet assembly or a faucet valve assembly; and
a contact member disposed on the body, the contact member configured to slidably engage with a valve stem of the faucet valve assembly, wherein the contact member is configured to press against the valve stem to increase a frictional force between the contact member and the valve stem over a full range of movement of the valve stem,
wherein the contact member defines an aperture, and wherein a size of the aperture is configured to decrease in response to a contact force between the contact member and the valve stem.

2. The assembly of claim 1 , wherein the body defines an opening configured to receive the valve stem, and wherein the contact member is configured to apply a contact force to the valve stem in a substantially perpendicular orientation relative to a central axis of the valve stem.

3. The assembly of claim 1 , wherein the friction ring is configured to prevent self-movement of the valve stem under an applied force resulting from a weight of a faucet handle that is coupled to the valve stem.

4. The assembly of claim 1 , further comprising a latch disposed on the body and extending radially outward from a central axis of the body, and wherein the latch is configured to rotatably couple the friction ring to at least one of the faucet assembly or the faucet valve assembly.

5. The assembly of claim 1 , wherein the contact member is integrally formed with the body as a single unitary structure.

6. The assembly of claim 1 , further comprising:
a faucet, including:
a faucet body;
a faucet valve assembly disposed substantially within the faucet body, the faucet valve assembly comprising a valve stem extending through a body opening in the faucet body, the valve stem pivotably coupled to the faucet valve assembly; and
a faucet handle coupled to the valve stem.

7. An assembly, comprising:
a friction ring including:
a body configured to couple the friction ring to at least one of a faucet assembly or a faucet valve assembly; and
a contact member disposed on the body, the contact member configured to slidably engage with a valve stem of the faucet valve assembly, wherein the contact member is configured to press against the valve stem to increase a frictional force between the contact member and the valve stem over a full range of movement of the valve stem,
wherein the contact member is one of a plurality of contact members disposed on the body, and wherein two of the contact members are configured to slidably engage with the valve stem on opposing sides of the valve stem.

8. The assembly of claim 7 , wherein the two contact members together define a gap, and wherein a width of the gap between the contact members increases with increasing distance from a central axis of the body.

9. The assembly of claim 7 , wherein the body defines an opening configured to receive the valve stem, and wherein the contact member is configured to apply a contact force to the valve stem in a substantially perpendicular orientation relative to a central axis of the valve stem.

10. The assembly of claim 7 , wherein the friction ring is configured to prevent self-movement of the valve stem under an applied force resulting from a weight of a faucet handle that is coupled to the valve stem.

11. The faucet assembly of claim 10 , wherein the contact member defines an aperture, and wherein a size of the aperture decreases in response to a contact force between the contact member and the valve stem.

12. The faucet assembly of claim 11 , wherein the size of the aperture is approximately constant throughout a full range of motion of the valve stem.

13. The assembly of claim 7 , further comprising a latch disposed on the body and extending radially outward from a central axis of the body, and wherein the latch is configured to rotatably couple the friction ring to at least one of the faucet assembly or the faucet valve assembly.

14. The assembly of claim 7 , wherein the contact member is integrally formed with the body as a single unitary structure.

15. The assembly of claim 7 , further comprising:
a faucet, including:
a faucet body;
a faucet valve assembly disposed substantially within the faucet body, the faucet valve assembly comprising a valve stem extending through a body opening in the faucet body, the valve stem pivotably coupled to the faucet valve assembly; and
a faucet handle coupled to the valve stem.

16. A faucet assembly, comprising:
a faucet body;
a faucet valve assembly coupled to the faucet body and comprising a movable valve stem;
a faucet handle coupled to the valve stem; and
a friction ring including a body and a contact member disposed on the body, the contact member comprising an arcuate wall that is slidably engaged with the valve stem,
wherein the contact member is a first contact member of a plurality of contact members disposed on the body, the plurality of contact members further comprising a second contact member coupled to the body on an opposing side of the valve stem as the first contact member, wherein the first contact member and the second contact member together define a gap, and wherein a width of the gap between the first contact member and the second contact member increases with increasing distance from a central axis of the body.
