Door skin, a method of etching a plate for forming a wood grain pattern in the door skin, and an etched plate formed therefrom
View Patent ↗The present invention is directed to a door skin having an exterior surface with an woodgrain pattern formed therein, and an etched plate for use as an embossing plate or with a molded die set, for forming the woodgrain pattern in the door skin. The exterior surface has outer portions lying on a first plane, spaced grooves recessed from the plane of the outer portions, and halftone portions. The halftone portions have spaced protrusions defined by channels, wherein the channels are recessed from the plane of the outer portions.
1. A molded article, comprising:
a molded door skin having an exterior surface;
variably spaced grooves formed into and running side-by-side along the exterior surface; and
halftone portions formed into the exterior surface defined by a plurality of intersecting channels that define a grid pattern,
wherein said spaced grooves are disposed on opposite sides of said halftone portions.
2. The molded article of claim 1 , wherein said grooves and said halftone portions form a wood grain pattern.
3. The molded article of claim 1 , wherein the grooves comprise a first set of grooves having an arrowhead-like configuration and a second set of grooves having a non-intersecting, variably spaced groove pattern.
4. The molded article of claim 1 , wherein the grooves have a variable depth.
5. The molded article of claim 1 , wherein the grooves have a greater depth than the halftone portions.
6. The molded article of claim 1 , further comprising stain applied to the door skin.
7. The molded article of claim 6 , wherein a variable amount of stain is retained by the grooves.
8. A door comprising:
a perimeter frame;
the door skin of claim 1 attached to a first side of the perimeter frame; and
a second door skin attached to a second side of the perimeter frame.
9. A molded article comprising:
an exterior surface having outer portions laying on a first plane;
halftone portions formed in the exterior surface defined by spaced protrusions and a plurality of intersecting channels in a grid pattern configured to simulate a wood tone, and
variable spaced grooves formed in and running side-by-side along the exterior surface, said spaced grooves being disposed on opposite side of said halftone portions.
10. The molded article of claim 9 , wherein the spaced protrusions are box shaped.
11. The molded article of claim 9 , wherein the spaced protrusions are cylindrical.
12. The molded article of claim 9 , wherein the intersecting channels have a depth between about 0.001 inches and about 0.003 inches.
13. The molded article of claim 9 , wherein the grooves comprise a first set of grooves having an arrowhead-like configuration and a second set of grooves having a non-intersecting, variably spaced groove pattern.
14. The molded article of claim 9 , wherein the molded article is formed from a material selected from the group consisting of sheet molding compound, medium density fiberboard, hardboard, fiberboard, and a thermoplastic material.
15. A molded article comprising:
a door skin having an exterior surface;
halftone portions formed in the exterior surface defined by spaced protrusions and a plurality of intersecting channels in a grid pattern configured to simulate a wood tone, and
variably spaced grooves formed in and running side-by-side along the exterior surface, said spaced grooved running along a side of said halftone portions.
16. The molded article of claim 15 , wherein the grooves have a variable depth.
17. The molded article of claim 15 , wherein the grooves comprise a first set of grooves having an arrowhead-like configuration and a second set of grooves having a non-intersecting, variably spaced groove pattern.
18. The molded article of claim 17 , wherein the second set of grooves is located over a stile of the door skin.
