Kinematic hinge with asymmetric pin hole

Abstract

A kinematic hinge with asymmetric pin hole is described. The pin hole includes two separated flat surfaces arranged at a relative angle to form a V-shape. The flat surfaces provide respective two kinematic contact points with a surface of a hinge pin arranged within the pin hole. A centerline of the V-shape is in a plane that is parallel to a plane of a hinge leaf associated with the asymmetric pin hole. A centerline of the V-shape is in a plane that intersects the plane of associated hinge leaf. The pin hole includes a teardrop shape provided by two arc segments joined by tangent line segments. Further included is a split V-block having two distant flat surfaces and corresponding rounded surfaces. The asymmetric pin hole is implemented in one or both hinge leaves of the kinematic hinge. The hinge pin is rigidly attached to one of the two hinge leaves.
