Abstract

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. 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.

First claim

We claim:

1. A door assembly including a door frame member, said door assembly comprising:
(a) at least one door panel; and
(b) the door frame having a plurality of frame members including a header and at least a pair of side jambs; wherein at least one frame member of the plurality of frame members includes
(i) a core; and
(ii) at least one top piece having one or more hollow enclosed cavities, said top piece adjoining said core to form a structural member with said core, said top piece including a rabbet portion and extending along a width of the core from one side of the core to an opposite side of the core to cover a distal end of the core at a distal end of the rabbet portion, and a stop portion, wherein said core extends the length of the top piece between the distal end of the rabbet portion and a distal end of the stop portion.

2. The door assembly of claim 1 including a trim profile.

3. The door assembly according to claim 1 , including a lower portion formed of a decay resistant material.

4. The door assembly according to claim 1 , wherein said top piece is a composite of cellulosic material and at least one other material.

5. A door assembly, said door assembly comprising:
(a) a door frame member including:
(i) a core;
(ii) a top piece adjoining said core to form a structural member with said core, wherein said top piece includes an enclosed hollow portion, and a stop portion and a rabbet portion adjoining to form a slot, the top piece extending along a width of the core from one side of the core to an opposite side of the core to cover a distal end of the core at a distal end of the rabbet portion, wherein said core extends the length between the distal end of the rabbet portion and a distal end of the stop portion; and

(b) a vertically oriented trim profile mating with said core and said top piece.

6. The door assembly according to claim 5 , wherein said door frame member is a door jamb.

7. The door assembly according to claim 5 , wherein said door frame member is a mullion.

8. A door frame member for a door frame assembly, comprising:
a hybrid jamb member including:
(a) a core,
(b) a top piece formed of a rigid extrusion of a cellulosic-plastic composite material,
(c) wherein said top piece aligns with said core along the length of the core, a rabbet portion of the top piece extending along a width of the core from one side of the core to an opposite side of the core to cover a distal end of the core at a distal end of the rabbet portion, and a stop portion, wherein said core extends the length of the top piece between the distal end of the rabbet portion and a distal end of the stop portion, and
(d) at least one enclosed hollow portion formed in the top piece between a top of the top piece and a base of the top piece.

9. The door frame member according to claim 8 including a trim profile, a length of the trim profile perpendicularly fitted to the length of said core and a length of said top piece.
