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.
