Abstract
A fully concealed, self-closing hinge for mounting a cabinet door to open through an angle of about 175 degrees on a cabinet frame, the hinge having only two pivoted links and three pivot axes. One link is connected to pivot relative to the door about one axis, the other link is connected to pivot relative to the frame about a second axis, and the two links are connected together to pivot relative to one another about the third axis. All three axes intersect one another at a common point on the hinge axis of the door in all positions of the door and constrain the door to swing in an arc about the hinge axis while enabling wide-angle opening of the door.
