Abstract

The present invention relates to a door skin comprising an exterior surface having outer portions lying on a first plane, spaced grooves recessed from the plane of the outer portions, and tonal portions having a planar area and a plurality of spaced depressions recessed from the plane of said planar area. The present invention is also directed to a method of etching a plate, for use with a molded die set, for embossing a wood grain pattern in the door skin, and the etched plate formed therefrom.

First claim

What is claimed is:

1. A door, comprising
a peripheral frame; and
at least one door skin attached to a side of the peripheral frame, the door skin having a stainable exterior surface comprising stiles, rails, and panels with molded grooves and molded tonal portions stainable with a stain, the molded grooves of the at least one door skin configured with variable depths and lengths relative to one another and variably spaced with respect to one another to collectively simulate an appearance of a naturally appearing wood grain tick pattern, the molded tonal portions of the at least one door skin comprising depressions configured to receive and retain sufficient stain to simulate an appearance of darkened naturally occurring wood grain background tone.

2. The door of claim 1 , wherein a first area of the stainable exterior surface has a first density of the molded tonal portions, wherein a second area of the stainable exterior surface has a second density of the molded tonal portions, and wherein the first density differs from the second density so that when stain is received and retained in the molded tonal portions the first and second areas simulate naturally occurring wood background tones having different degrees of darkness.

3. The door of claim 1 , wherein the molded grooves have a greater depth than the depressions.

4. The door of claim 1 , wherein the at least one door skin comprises a sheet molding compound, polystyrene, or polypropylene.

5. The door of claim 1 , wherein the at least one door skin comprises medium density fiberboard or hardboard.

6. The door of claim 1 , wherein the molded grooves extend parallel to one another.

7. The door of claim 1 , wherein the stainable exterior surface further comprises outer portions lying between the molded grooves.

8. The door of claim 7 , wherein the outer portions are planar with one another, and wherein the grooves are recessed from the outer portions by between about 0.005 inch to about 0.015 inch.

9. The door of claim 1 , wherein the molded tonal portions form an outer planar area.

10. The door of claim 9 , wherein bases of the depressions are recessed between about 0.001 inch and about 0.003 inch from the outer planar area.

11. A door, comprising
a peripheral frame; and
first and second door skins attached to opposed sides of the peripheral frame, each door skin having a stainable exterior surface comprising stiles, rails, and panels with molded grooves and molded tonal portions stainable with a stain, the molded grooves of the at least one door skin configured with variable depths and lengths relative to one another and variably spaced with respect to one another to collectively simulate an appearance of a naturally appearing wood grain tick pattern, the molded tonal portions of the at least on door skin comprising depressions retaining a sufficient amount of the stain to simulate an appearance of darkened naturally occurring wood grain background tone.

12. The door of claim 11 , wherein a first area of the stained exterior surface has a first density of the molded tonal portions retaining a first amount of the stain to provide a first tone, wherein a second area of the stained exterior surface has a second density of the molded tonal portions retaining a second amount of the stain to provide a second tone, and wherein the first tone differs from the second tone to simulate multiple naturally occurring wood background tones of different degrees of darkness.

13. The door of claim 11 , wherein the molded grooves have a greater depth than the depressions.

14. The door of claim 11 , wherein the door skin comprises a sheet molding compound, polystyrene, or polypropylene.

15. The door of claim 11 , wherein the door skin comprises medium density fiberboard or hardboard.

16. The door of claim 11 , wherein the molded grooves extend parallel to one another.

17. The door of claim 11 , wherein the stained exterior surface further comprises outer portions lying between the molded grooves.

18. The door of claim 17 , wherein the outer portions are planar with one another, and wherein the grooves are recessed from the outer portions by between about 0.005 inch to about 0.015 inch.

19. The door of claim 11 , wherein the molded tonal portions form an outer planar area.

20. The door of claim 19 , wherein bases of the depressions are recessed between about 0.001 inch and about 0.003 inch from the outer planar area.
