Continuous threshold assembly with modular interlocking substrate sections

A threshold assembly for an entryway, said threshold assembly comprising:

• an elongated substrate having inside and outside edges and being formed from at least two substrate sections joined together in end-to-end relationship;
• the substrate sections being formed of recycled plastic and a filler selected from the group consistent of rice hull and wood flour;
• a sill mounted to and at least partially covering said substrate, said sill defining a sill deck supported by said substrate and an upstanding dam disposed between said inside and outside edges of said substrate;
• and
• wherein a nosing portion of said substrate extends along said inside edge of said substrate, the nosing portion of said substrate and the dam portion of said sill forming walls of an upwardly open channel extending along said threshold assembly and further comprising a threshold cap positioned within said upwardly open channel to underlie a closed door of an entryway in which said threshold is installed.

A threshold assembly comprising:

• at least a first and second substrate section;
• the first substrate section having at least one protruding element along at least one end of the first substrate section;
• the second substrate section having at least one slot along at least one end of the second substrate;
• the protruding element of the first substrate section being slidingly engaged in end-to-end relationship with the slot of the second substrate section wherein the two substrate sections are in substantially the same plane during engagement;
• the at least first and second substrate sections, are disposed at least partially beneath a sill and being capable of being affixed between bottom ends of a plurality of jambs to form a doorway;
• an upwardly open channel formed at least in part by one of the sill and substrate sections;
• and the assembly forming a threshold and capable of being positioned between the plurality of jambs.
