Door assembly
A door assembly and a frame member for a door assembly. The door assembly may include at least one door panel and a door frame having a plurality of frame members including a header and a pair of side jambs. The invention may also be considered a frame member including a storage compartment. The frame member may include a core; and a top piece adjoining the core to form a structural member. The core and the top piece may be a composite of cellulosic material and at least one other material. The top piece may be a two-piece top piece and may include hollow cavities. Also disclosed are door jamb frame members and mullion frame members.
1. A door assembly comprising:
a core including a channel, wherein said channel includes openings,
a two-piece top piece having one or more enclosed hollow cavities with said openings extending from an interior side of said core through to the enclosed hollow cavities, said top-piece including a top piece base having excerpts so that the base is a discontinuous base along the length of a frame member, and the top-piece adjoining said core to form a structural member with said core;
said two-piece top piece including a removable top piece cover, and
a storage compartment formed within one or more of the enclosed hollow cavities, the storage compartment adapted to house door components;
wherein the storage compartment and components are accessible when the removable top piece cover is removed.
2. The door assembly of claim 1 including a trim profile.
3. The door assembly according to claim 1 , wherein the door assembly includes a lower portion formed of a decay resistant material.
4. The door assembly according to claim 1 , wherein said two-piece top piece is a composite of cellulosic material and at least one other material.
5. The door assembly according to claim 1 , wherein said excerpts are adapted to provide a space for inclusion of a component within the frame member.
6. The door assembly according to claim 5 , including a stop portion and a rabbet portion, and wherein said rabbet portion is generally L-shaped and a proximate end of said stop portion overlaps a corresponding proximate end of said rabbet portion.
7. The door assembly according to claim 6 , the distal end of said rabbet portion including an overlap of the sides of the underlying core.
8. The door assembly according to claim 5 , wherein said two-piece top piece is a cellulosic-plastic composite.
9. The door assembly according to claim 8 , wherein the amount of cellulosic material in said cellulosic-plastic composite is between about 20 wt. % and about 70 wt. % of the weight of said cellulosic-plastic composite.
10. The door assembly according to claim 8 , wherein the thickness of the two-piece top piece is between about 10% and about 50% of the thickness of said frame member.
11. The door assembly according to claim 5 wherein said frame member is a door jamb.
12. The door assembly according to claim 5 wherein said frame member is a door mullion.
13. The door assembly according to claim 5 including:
the top piece cover having a downwardly projecting outer leg, a midleg, and an inner leg, and
the top piece base having an upwardly projecting outer leg, a mid leg, and an inner leg,
wherein the outer leg of the top piece cover mates with the outer leg of the base and the mid leg of the top piece cover and the mid leg of the base are configured to contact each other in a bias position, securing the top piece cover to the base.
