Door jamb for flush in-swing door

A door jamb for interfacing with an in-swing door installed at a door opening defined at least in part by said doorjamb, the in-swing door having a front surface, a latch face and a hinge face, said door jamb comprising:

• a) first and second, spaced side wall segments adapted to be attached to opposite sides of a wall stud at the door opening;
• b) third, fourth, fifth and sixth contiguous wall segments located between said first side wall and said second side wall segments, said third and fourth wall segments forming a protrusion at their juncture, said protrusion and said first side wall segment being offset from each other and thereby defining a space (d10) adapted to be filled with a wall finishing material;
• c) said fourth wall segment extending parallel to and spaced from said sixth wall segment such that said fourth, fifth and sixth wall segments together form a stepped surface against which a complimentary shaped door latch face surface of the in-swing door is positioned when in the closed position and wherein the door front surface lies closely adjacent said protrusion to create a flush finish of the door front surface with the wall surrounding the door opening along said door jamb first side wall segment with said jamb protrusion lying closely adjacent said latch face front edge, the interface between said door jamb and in-swing door allowing the in-swing door to be pivoted from the closed position to open in a direction directed against the door front surface and toward the plane in which said second wall segment lies.
