A door frame with a substantially continuous sealing surface supports a door with a substantially continuous sealing member mounted thereon. A stepped U-shaped frame member has an opening at one end that is closed with a square-cut member, such as a threshold. The frame, threshold and hinges mounted on the frame provide a substantially continuous sealing surface. The bores of the hinge knuckles may be matched with bushings in the bores, so that the bushings must be properly oriented. The heads of the bushings may have at least two steps or raised contact surfaces and at least two indentations or depressed contact surfaces. When the doors are opened, the steps on their bushings in the pivoting hinge leaves drop into the indentations in the adjacent fixed hinge leaf and hold the door in position.

A door assembly comprising:a frame assembly designed and adapted to define a substantially unbroken sealing surface around substantially the entire periphery of said frame assembly; and a first door having a substantially continuous sealing member mounted on said first door; said sealing member being designed and adapted to engage said sealing surface and thereby provide a substantially continuous seal around said door when said door is closed; wherein said frame assembly has one or more frame notches, further comprising:a second door and a plurality of hinge assemblies supporting said first door and said second door, said hinge assemblies comprising: a stepped fixed hinge leaf, designed and adapted to be mounted in said frame notch and having an outwardly facing edge with one or more hinge leaf notches; a first hinge leaf designed and adapted to support said first door; and a stepped, second hinge leaf designed and adapted to support said second door and to pivot into said hinge leaf notch when said second door is pivoted into a closed position, whereby sections of said second hinge leaf, said fixed hinge leaf and said frame are substantially coplanar and define a portion of said substantially continuous sealing surface. 3. A door assembly according to claim 2 herein said door assembly comprises a prime door and a screen door and said second hinge assembly supports said screen door.4. A door frame assembly comprising:a stepped, U-shaped frame member having: a first, laterally facing section designed and adapted to be mounted to a structure; a second, outwardly facing section designed and adapted to define a sealing surface; a third, exterior terminating section; and a stepped, square cut threshold having: a outwardly facing section that is substantially coplanar with said outwardly facing section of said frame member; and an outer section that extends outward from said outwardly facing section and has an end that is square cut with and substantially coplanar with an end of said exterior terminating section, whereby there is a space between the end of said outer section of the threshold and the third exterior terminating section of said U-shaped frame member; and a plug attached to at least one of said threshold and said frame member, and closing said space. 5. A door according to claim 4 wherein said plug comprises nylon.6. A door assembly having at least one hinge assembly mounted on a door frame, said hinge assembly comprising:a mounting plate having an upper fixed knuckle and a lower fixed knuckle, each of said knuckles having bores with a common axis; stepped bushings with first sections mounted in said bores and second sections that are larger than said bores, said bushings being inserted into said bores so that the larger section of one bushing is above the upper knuckle and the larger section of another bushing is above the lower knuckle; a hinge leaf having a leaf knuckle that is positioned between and has a bore that is substantially coaxial with the bores of said upper fixed knuckle and said lower fixed knuckle; a stepped leaf bushing having a first section mounted in said leaf bore and a second section that is larger than said leaf bore, said leaf bushing being inserted into said leaf bore so that said second section of said leaf bushing is below said leaf knuckle and is supported by the bushing mounted in the lower knuckle; and a metallic pin extending through said bushings, whereby said hinge leaf can pivot with respect to said mounting plate with minimal metal-to metal wear between said knuckles, and between said pin and said knuckles; said bores comprising narrower orienting grooves and at least one wider orienting groove with a bottom that is wider than a bottom of said narrower orienting groove; and the bodies of said bushings comprising narrower orienting ribs designed to fit into said narrower orienting grooves, and at least one wider orienting rib designed to fit into said wider orienting groove. 7. A door assembly according to claim 6 wherein said bores have at least two of said wider orienting grooves and the bodies of said bushings have at least two of said wider orienting ribs.8. A door assembly according to claim 6 wherein said heads of said bushings comprise contact surface on the opposite side of the heads from the bodies of the bushings, and said contact surfaces comprise at least two raised contact surfaces, at least two depressed contact surfaces, each of said depressed contact surfaces being between two of said steps, with inclined surfaces between said steps and said valleys.9. A door assembly according to claim 8 wherein said steps are substantially flat and coplanar, and said valleys are substantially flat, coplanar and parallel to said steps.10. A door assembly to claim 9 wherein said inclined surfaces have a substantially constant slope.11. A door assembly according to claim 6 further comprising at least one annular plug inserted into the opposite end of one of said bores from the larger end of the bushing inserted into said bore.12. A door assembly according claim 11 wherein said annular plugs are inserted into the opposite ends of all of bores in the hinge knuckles of said assembly from, and said metallic pin extends through all of said plugs and bushings.13. A door assembly according to claim 6 wherein said bushings comprise acetal plastic.14. A door assembly comprising:a door with a door groove designed and adapted to support a weather seal; a hinge leaf having a leaf groove designed and adapted to support a weather seal, said leaf groove being aligned with the door groove; and a weather seal extending through the door groove and the leaf groove; wherein said door comprises an edge member having an arm extending therefrom and said door groove comprises a slot with a cruciform cross-section in said arm; and said leaf groove comprises a cruciform slot. 15. A door assembly according to claim 14 wherein said weatherseal comprises a cruciform section designed and adapted to be mounted in said grooves, and a serpentine section extending from said cruciform section.16. A door assembly according to claim 15 wherein said cruciform section of said weather seal comprises polypropylene and said serpentine section comprises a thermoplastic elastomer, and said polypropylene and said thermoplastic elastomer are co-extruded to form said weather seal.17.
