Abstract

A door assembly allows one to easily and freely change a hinged side and an opening direction of a door when or after a resident moves into a house. Detachable inner frames having doorstop portions, flat portions, and locking nails are mounted to locking grooves in left and right vertical outer frames around spacers and a door main body is mounted to a heelpost side flat portion through hinges. By dividing a doorframe into the vertical outer frames and the inner frames, in order to change a hinged side of the door, the inner frames are pulled out from the vertical outer frames and inserted into the locking grooves in the vertical outer frames after changing orientation of the inner frames according to the hinged side or exchanging the inner frames for the inner frames suitable for the hinged side and the opening direction to thereby easily change the hinged side of the door main body.

Dependent claims

A hinged door frame kit for forming a door frame structure installable in a wall opening, comprising:

a door;
an outer frame body including right and left vertical outer frame members respectively having right and left inside faces which when installed in the wall opening have said left and right inside faces perpendicular to a plane of the wall opening and opposing one another;
an inner frame;
said inner frame including a heelpost side inner frame member configured to hingeably accept said door, said heelpost side inner frame member being installable to both said right and left inside faces;
said inner frame including a door end side inner frame member installable to both said right and left inside faces;
a pair of locking grooves formed in parallel over a full length in a longitudinal direction of the left and right inside faces;
said heelpost side inner frame member and said door end side inner frame member being integrally formed of a door stop portion thereof and a flat portion thereof that extends from said door stop portion;
locking nails formed along opposing sides said heelpost side and door end side inner frame member;
said locking nails being detachably insertable into said locking grooves such that:
said heelpost side inner frame member is installable in both said left and right vertical outer frame members when said left and right vertical outer frame members are already installed in said wall opening;
and
said door end side inner frame member is installable in both said left and right vertical outer frame members when said left and right vertical outer frame members are already installed in said wall opening;
thereby said heelpost side inner frame member and said door end side inner frame member are interchangeable between installation in said left and right vertical outer frame members when said left and right vertical outer frame members are already installed in said wall opening;
and
spacers disposed between said left and right outer vertical frame members and both said heelpost side and door end side inner frames.
