Abstract
A pair of hinges have cases mounted at the very corners of a cabinet opening to define a pivot axis for a door. The cases are relatively narrow in the direction from front to back but of significant size at the region of the corner whereby the cabinet is braced by the hinge cases. Quadrilateral links are pivoted by and extend frontally of the corresponding cabinet cases to move in spaced parallel planes without interference. The hinge leaves for the door have cases accommodated in slots at the back of the door that extend perpendicular to the pivot axis. These cases pivotally mount the other ends of the quadrilateral links for movement without interference. By virtue of the staggered arrangement, a door movement in excess of 90.degree. is readily provided. A spring for self closing operation is accommodated in the case for one of the hinge leaves.
