Abstract

A plumbing fixture having a multi-color appearance includes a first portion including a first finish having a first appearance and a second portion including a second portion having a second appearance that differs from the first appearance. The plumbing fixture further includes a transition region between the first portion and the second portion, wherein the appearance of the third region is graduated from the first appearance to the second appearance between a first end of the transition region adjacent the first portion and a second end of the transition region adjacent the second portion. The plumbing fixture has an ombré appearance as a result of the graduated transition between the first portion and the second portion.

First claim

What is claimed is:

1. A plumbing fixture having a multi-color appearance comprising:
a first vacuum deposition coating comprising a first finish having a first appearance;
a second vacuum deposition coating comprising a second finish having a second appearance that differs from the first appearance;
a gradient region between the first vacuum deposition coating and the second vacuum deposition coating defined by varying intensities of the first and second vacuum deposition coatings, wherein the appearance of the gradient region is graduated from the first appearance to the second appearance between a first end of the gradient region adjacent the first vacuum deposition coating and a second end of the gradient region adjacent the second vacuum deposition coating; and
whereby the plumbing fixture has an ombre appearance as a result of the graduated transition between the first coating and the second coating.

2. The plumbing fixture of claim 1 , wherein the plumbing fixture is selected from the group consisting of a faucet, a faucet handle, water piping, a hose, a sink, a bathtub, a whirlpool, and a spa.

3. The plumbing fixture of claim 1 , wherein the varying intensities of the first and second vacuum deposition coatings comprise the first vacuum deposition coating at a first percentage in a range of about 5% to about 95% with the remaining balance as a second percentage of the second vacuum deposition coating.

4. The plumbing fixture of claim 1 , wherein the first finish and the second finish are selected from at least one of polished chrome, brushed chrome, polished French gold, polished titanium, brushed titanium, polished rose gold, polished modem gold, polished tungsten, polished modem brass, satin titanium, polished satin chrome, satin bronze, polished brass, satin brass, oil-rubbed bronze, polished nickel, brushed nickel, or matte black.

5. The plumbing fixture of claim 1 , further comprising:
a priming layer on the plumbing fixture disposed between the plumbing fixture and the first finish or between the plumbing fixture and the second finish.

6. A multi-color plumbing fixture comprising:
a first vacuum deposition coating having a first appearance;
a second vacuum deposition coating having a second appearance that differs from the first appearance;
a gradient portion extending between the first vacuum deposition coating and the second vacuum deposition coating defined by varying intensities of the first and second vacuum deposition coatings, wherein the gradient portion has an appearance that transitions in graduated fashion from the first appearance at a first end thereof adjacent the first vacuum deposition coating to the second appearance at a second end thereof adjacent the second vacuum deposition coating; and
wherein the multi-color plumbing fixture is selected from the group consisting of a faucet, a faucet handle, water piping, a hose, a sink, a bathtub, a whirlpool, and a spa.

7. The plumbing fixture of claim 6 , wherein the first appearance comprises a first finish and the second appearance comprises a second finish.

8. The plumbing fixture of claim 7 , wherein the first finish and the second finish are selected from at least one of polished chrome, brushed chrome, polished French gold, polished titanium, brushed titanium, polished rose gold, polished modem gold, polished tungsten, polished modern brass, satin titanium, polished satin chrome, satin bronze, polished brass, satin brass, oil-rubbed bronze, polished nickel, brushed nickel, or matte black.

9. The plumbing fixture of claim 6 , wherein the varying intensities of the first and second vacuum deposition coatings comprise a first percentage of the first vacuum deposition coating in a range of about 5% to about 95% of the first appearance with the remaining balance as a second percentage of the second appearance.

10. A method of coating a plumbing fixture, comprising:
depositing a first coating on the plumbing fixture;
selectively applying a masking material in a graduated fashion over at least a portion of the first coating to define a gradient from a first portion of the plumbing fixture that is substantially completely covered by the masking material to a second portion of the plumbing fixture that has substantially no masking material;
depositing a second coating over the masking material; and
removing the masking material from the plumbing fixture such that the plumbing fixture has a surface finish including a gradient region representing a gradual transition between the first coating and the second coating;
wherein selectively applying the masking material in a graduated fashion comprises spraying the masking material at varying intensities,
wherein the first coating and the second coating are selected from at least one of physical vapor deposition coatings, chemical vapor deposition coatings, chemical vapor deposition coatings and atomic layer deposition coatings.

11. The method of claim 10 , wherein the gradient region comprises a first percentage of the first coating and a second percentage of the second coating.

12. The method of claim 11 , wherein the first percentage is in a range of about 5% to about 95% with the remaining balance as the second percentage.

13. The method of claim 10 , wherein the first coating defines a first finish having a first appearance, and wherein the second coating defines a second finish having a second appearance that is different from the first appearance.

14. The method of claim 10 , wherein the masking material includes at least one of molybdenum disulfide, tungsten disulfide, boron nitride, or graphite.

15. The method of claim 10 , wherein the masking material comprises a material with a low outgassing rate suitable for vacuum deposition.
