A door hinge arrangement for a door is provided including a hinge bearing and a hinge pin adapted to be received in the hinge bearing and being rotatable in the hinge bearing about a vertical axis of the hinge pin. The hinge pin has a protruding cam portion extending perpendicular to the axis and the hinge bearing has a recess formed in a side wall to receive a length of the cam portion when the hinge pin is in a first angular orientation relative to the hinge bearing corresponding to a closed position. When the hinge pin is rotated relative to the hinge bearing to a second angular orientation, the cam acts against the recess to translate the axis of the pin from a first axial position to a second axial position, such that the hinge pin will first be translated laterally as the hinge pin is rotated, and then the hinge pin will be rotated about the second axial position.
