Abstract

A door assembly comprises a rectangular door frame that has a first, second, third, and fourth frame member. The first frame member has an outer surface that has a first pair of parallel slots. A first parallel flange protrudes from and perpendicular to the outer surface between the parallel slots. A vane extends from the first frame member to the second frame member between the third and fourth frame members. The vane has a first end that includes a pair of parallel flanges fitted into the parallel slots such that a rear surface of the first planar flange is arranged between rear edges of the first parallel flanges. A bar is mounted to the rear surface of the first planar flange and configured to hold the rear edges of the first parallel flanges in substantially the same plane as the rear surface of the first planar flange.

First claim

What is claimed is:

1. A door assembly comprising:
a rectangular door frame having a first, second, third, and fourth frame member;
an outer surface of the first frame member having a first pair of parallel slots
a first planar flange arranged between the first pair of parallel slots and protruding out from and perpendicular to the outer surface;
a vane extending from the first frame member to the second frame member between the third and fourth frame members, a first end of the vane including a first pair of parallel flanges fitted into the first pair of slots such that a rear surface of the first planar flange is arranged between rear edges of the first parallel flanges, wherein the first pair of parallel flanges are straight, wherein the vane comprises:
a cavity into which a flexible insulating strip is inserted, wherein a cross-sectional form of the flexible insulating strip is a hexagon; and
a tab that secures the flexible insulating strip in place in the cavity;

a bar mounted to the rear surface of the first planar flange and configured to hold the rear edges of the first parallel flanges in a substantially same plane as the rear surface of the first planar flange, wherein the bar is mounted to the first planar flange by a bolt through the bar and first planar flange;
a second pair of parallel slots on the outer surface of the first frame member;
a second planar flange arranged between the second pair of parallel slots and protruding out from and perpendicular to the outer support surface;
wherein the second planar flange is offset from the first planar flange in a first dimension by a first amount, wherein a length along the first dimension corresponds to the space between the third frame member and the forth frame member, and wherein the second planar flange is positioned relative to the first planar flange such that the bar rests on a rear surface of the second planar flange when the bar is mounted to the rear surface of the first planar flange;
a third planar flange;
wherein the second frame member is positioned opposite the first frame member with respect to the door frame and comprises a first sub member releasably attached to a second sub member, the first sub member comprising a third pair of parallel slots, the third planar flange arranged between the third pair of parallel slots and protruding out from and perpendicular to an outer surface of the first sub member;
a second end of the vane comprising a second pair of parallel flanges fitted into the third pair of parallel slots such that a rear surface of the third planar flange is arranged between rear edges of the second pair of parallel flanges, wherein the second pair of parallel flanges is straight;
a second bar mounted to the rear surface of the third planar flange and configured to hold the rear edges of the second parallel flanges in a substantially same plane as the rear surface of the third planar flange; and
a fourth planar flange, offset from the first planar flange in the first dimension by a second amount, different than the first amount, and in a second dimension, wherein a length along the second dimension corresponds to a thickness of the door assembly.
