Abstract
A pivotal-axis changing hinge has a stationary leaf, a pivoting leaf, a pintle assembly and a cam. The pivoting leaf and stationary leaf are respectively connected securely to a cover having a rear edge and a keyway and a base having an elongated gudgeon. A parabolic edge is formed at an edge near the elongated gudgeon. The pintle assembly is mounted through the keyway and pivotally through the elongated gudgeon to allow the leaves to pivot along a pivotal axis of the pintle assembly. The cam is mounted on the pintle assembly, rotates simultaneously with the pintle assembly and has a protrusion mounted slidably on the parabolic edge to move the pintle assembly and the cover perpendicularly away from the base when the cover is pivoting. Consequently, the proximal edge of the cover is kept from colliding with the base and the rotating angle of the cover is expanded.
