Doors assembly and an improved method for making a doors sill assembly

A door sill assembly constructed and arranged to be mounted along a lower edge of the doorway between first and second side jambs installed in a doorway located at an exterior of a building in conjunction with a door panel movable between open and closed positions with respect to the doorway, said door sill assembly comprising:

• a sub-sill having a peripheral wall including a bottom wall, first and second end walls extending generally upwardly from said bottom wall at opposing end portions of said sub-sill, a rear wall extending generally upwardly from and generally longitudinally between said end walls, and a front wall extending generally upwardly from and generally longitudinally between said end walls opposite said rear wall, said walls of said sub-sill providing interior surfaces that cooperate to define an open fluid-receiving trough extending between said front and rear walls and said first and second end walls, said peripheral wall having one or more openings formed therethrough to allow fluid in the trough to drain from the trough to the building exterior when said door frame assembly is installed in the doorway with said front wall facing the building exterior, said end and rear walls being constructed and arranged to prevent fluid in the trough from flowing into the building interior,
• a tread structure mounted to said sub-sill so as to cover said sub-sill, said tread structure and said sub-sill being constructed and arranged such that fluid flowing over said tread structure towards building interior is directed into the trough of said sub-sill and then is allowed to drain out from said trough to the building exterior through the one or more openings in the peripheral wall of said sub-sill,
• said door sill assembly being constructed and arranged such that the opposing end portions of said sub-sill connect with the first and second side jambs with portions of the first and second side jambs extending inside said first and second end walls, respectively, and downwardly into said trough adjacent opposing end portions of said tread structure so that fluid flowing over said tread structure towards the building interior adjacent to said first and second side jambs is allowed to flow downwardly into the trough of said sub-sill between said tread structure and said side jambs and then is allowed to drain out from said trough to the building exterior through the one or more openings in the peripheral wall of said sub-sill.

• a tread structure mounted to said sub-sill so as to cover said sub-sill, said tread structure and said sub-sill being constructed and arranged such that fluid flowing over said tread structure towards building interior is directed into the trough of said sub-sill and then is allowed to drain out from said trough to the building exterior through the one or more openings in the peripheral wall of said sub-sill,
• said first and second side jambs and said door sill assembly being constructed and arranged such that said first and second side jambs connect to the opposing end portions of said sub-sill with portions of said first and second side jambs extending inside said first and second end walls, respectively, and downwardly into said trough adjacent opposing end portions of said tread structure so that fluid flowing over said tread structure towards the building interior adjacent to said first and second side jambs is allowed to flow downwardly into the trough of said sub-sill between said tread structure and said side jambs and then is allowed to drain out from said trough to the building exterior through the one or more openings in the peripheral wall of said sub-sill;
• and
• a door panel constructed and arranged to be mounted to said door frame assembly for movement between an open position wherein said door panel uncovers the doorway to allow passage therethrough and a closed position wherein said door panel covers the doorway to prevent passage therethrough.

A door frame assembly constructed and arranged to be installed in a doorway located at an exterior of a building in conjunction with a door panel movable in a generally rectilinear manner between open and closed positions with respect to the doorway, said door frame assembly comprising:

• first and second side jambs constructed and arranged to be mounted along first and second generally vertically extending sides of the doorway;
• a door sill assembly constructed and arranged to be mounted along a lower edge of the doorway between said first and second side jambs, said door sill assembly comprising:
• a sub-sill having surfaces defining an interior fluid receiving space which has one or more openings to allow fluid therein to drain therefrom to the building exterior when said door frame assembly is installed in the doorway, said sub-sill being constructed and arranged to prevent fluid in the fluid receiving space from flowing into the building interior,
• a tread structure mounted to said sub-sill so as to cover said sub-sill, said tread structure and said sub-sill being constructed and arranged such that fluid flowing over said tread structure towards building interior is directed into the fluid receiving space of said sub-sill and then is allowed to drain out to the building exterior through said one or more openings,
• said tread structure providing a door panel supporting lip extending generally upwardly therefrom, said lip being constructed and arranged such that the rectilinearly movable door panel can be mounted on said lip and supported thereby for generally rectilinear movement between opened and closed positions, said tread structure having structure that cooperates with said lip to define a groove extending alongside said lip rearwardly thereof, said groove being configured to guide fluid flowing over said lip towards the opposing ends of said tread structure for drainage to the exterior of the building;
• said first and second side jambs and said door sill assembly being constructed and arranged such that said first and second side jambs connect to the opposing end portions of said sub-sill in such a manner that fluid flowing over said tread structure towards the building interior adjacent to said first and second side jambs is allowed to flow downwardly into the fluid receiving space of said sub-sill between said tread structure and said side jambs and then is allowed to drain out to the building exterior through said one or more openings.
