Abstract
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 two-piece 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 door assembly may further include at least one adjacent panel. Also disclosed are door jamb frame members and mullion frame members.
Claims22
A door assembly, said door assembly comprising:
- (a) at least one door panel;
- and
- (b) a door frame having a plurality of frame members including a header and a mullion;
- wherein the mullion includes
- (i) a core;
- and
- (ii) at least one top piece adjoining said core to form a structural member with said core and wherein said top piece is a composite of cellulosic material and plastic material,
- wherein the amount of cellulosic material in said cellulosic-plastic composite is at least 20 wt. % of the weight of said cellulosic-plastic composite when a thickness of the top piece is at least 10% of the thickness of the at least one frame member,
- wherein said core includes a stop portion and a rabbet portion and said core is entirely enclosed within said top piece.
A door assembly, said door assembly comprising:
- (a) a door frame having a plurality of frame members including a header and a side jamb;
- wherein at least one frame member includes:
- (i) a core having a raised portion;
- and
- (ii) a two-piece top piece adjoining said core to form a structural member with said core and said top piece is a composite of cellulosic material and at least one other material;
- (b) a first piece of said two-piece top piece having a distal end covering a distal end of said core, said distal end of said first piece extending in an L-shape over a top of the core and having a proximal end terminating at the raised portion of the core with the distal end terminating flush with a bottom of the core;
- (c) a second piece of said two-piece top piece having a second distal end covering an opposite distal end of said core, said second distal end extending in an L-shape over a raised top of the core to a second piece proximate end, the second piece proximate end terminating in an overlapping and non-planar position with the proximate end of the first piece with the distal end terminating flush with a bottom of the core,
- and wherein a slot is interspersed between said first piece and between said second piece so that the first piece and second piece are discontinuous one with the other.
