Jamb and threshold assembly with watertight seals

DETAILED DESCRIPTION The present invention, in one preferred embodiment thereof, comprises a door jamb and threshold assembly that forms a watertight seal at the bottom corners of a door when the door is closed.
The assembly comprises a pair of spaced vertical side jambs and a door sill and threshold assembly that spans the bottom ends of the jambs.
A head jamb spans the tops of the side jambs to frame the opening.
Flexible rubber or foam weather stripping is provided around the periphery of the opening and is positioned so that it becomes compressed between the stop of the jambs and a closed door to provide a seal around the periphery of the door.
A rubberized or foam pad is fixed to the side jambs at each of the bottom ends thereof where the jamb meets the threshold and sill assembly.
The pad has a tapered portion that is positioned to be compressed between the bottom of the outside vertical edge of the door and the door jamb when the door is closed to provide a seal.
In addition, the pad includes a projection that is positioned between the fixed and flexible legs of the weather stripping at the bottom corners of the side jambs.
When the entryway door is closed, the weather stripping seals around the perimeter of the door as usual.
At the bottom corners of the door, the projections of the pads between the legs of the weather stripping reinforces the weather stripping in this region causing it to bear with greater force and seal better against the door.
A portion of the projection formed as a part of the pad extends downwardly beyond the lower extent of the door to reinforce the weather stripping that rests against the front edge of the threshold cap beneath the closed door.
Thus, when the door is closed, the weather stripping at the bottom corners of the door is compressed tightly against the door and the continuation of the weather stripping below the door is compressed tightly against the front of the threshold cap.
In addition, the portion the weather stripping that spans the space between the bottom of the door and the threshold cap is pressed into and conforms to the shape and contours of the space
