A door hinge for supporting a door (30a, 30b) to a door jamb (10a, 10b) and being operable between a first, closed configuration and a second, fully open configuration, the door hinge comprising: a body part for attaching to a door jamb (10a, 10b), wherein the body part includes a first jamb face and a second jamb face which is generally orthogonal to the first jamb face so as to be mortisable in the door jamb (10a, 10b); a door part for attaching to a door (30a, 30b), wherein the door part includes a door front face so as to be mortisable in the door (30a, 30b); and a pivot coupling which pivotally connects the door part to the body part, wherein the pivot coupling comprises: a first arm which is coupled to the body part about a first fixed pivot axis and to the door part about a first displaceable pivot axis, the first fixed pivot axis being located outwardly of the first jamb face, and the first displaceable pivot axis being displaced from a first location when the hinge is in the closed configuration to a second location along and away from the first jamb face when the hinge is in the fully open configuration; and a second arm which is coupled to the body part about a second fixed pivot axis and to the door part about a second displaceable pivot axis, the second fixed pivot axis being located inside the body part, and the second displaceable pivot axis being displaced from a first location when the hinge is in the closed configuration to a second location along and away from the first jamb face when the hinge is in the fully open configuration; wherein the door front face is generally parallel to and faces in a first direction towards the first jamb face when the hinge is in the closed configuration and generally orthogonal to the first jamb face and faces in a second direction when the hinge is in the fully open configuration. a body part for attaching to a door jamb (10a, 10b), wherein the body part includes a first jamb face and a second jamb face which is generally orthogonal to the first jamb face so as to be mortisable in the door jamb (10a, 10b); a door part for attaching to a door (30a, 30b), wherein the door part includes a door front face so as to be mortisable in the door (30a, 30b); and a pivot coupling which pivotally connects the door part to the body part, wherein the pivot coupling comprises: a first arm which is coupled to the body part about a first fixed pivot axis and to the door part about a first displaceable pivot axis, the first fixed pivot axis being located outwardly of the first jamb face, and the first displaceable pivot axis being displaced from a first location when the hinge is in the closed configuration to a second location along and away from the first jamb face when the hinge is in the fully open configuration; and a second arm which is coupled to the body part about a second fixed pivot axis and to the door part about a second displaceable pivot axis, the second fixed pivot axis being located inside the body part, and the second displaceable pivot axis being displaced from a first location when the hinge is in the closed configuration to a second location along and away from the first jamb face when the hinge is in the fully open configuration; wherein the door front face is generally parallel to and faces in a first direction towards the first jamb face when the hinge is in the closed configuration and generally orthogonal to the first jamb face and faces in a second direction when the hinge is in the fully open configuration. a first arm which is coupled to the body part about a first fixed pivot axis and to the door part about a first displaceable pivot axis, the first fixed pivot axis being located outwardly of the first jamb face, and the first displaceable pivot axis being displaced from a first location when the hinge is in the closed configuration to a second location along and away from the first jamb face when the hinge is in the fully open configuration; and a second arm which is coupled to the body part about a second fixed pivot axis and to the door part about a second displaceable pivot axis, the second fixed pivot axis being located inside the body part, and the second displaceable pivot axis being displaced from a first location when the hinge is in the closed configuration to a second location along and away from the first jamb face when the hinge is in the fully open configuration; wherein the door front face is generally parallel to and faces in a first direction towards the first jamb face when the hinge is in the closed configuration and generally orthogonal to the first jamb face and faces in a second direction when the hinge is in the fully open configuration.
