HINGE MECHANISM

摘要

To provide a hinge which achieve durability, good feeling, size and weight reduction, for portable phones or laptop computers which require to be smaller and lighter. A hinge mechanism that generates a stress at the start and end points of arbitrary opening and closing range can be constructed by causing one cam set of two cam sets in which a rotating cam 4 and a fixed cam 5 engage only one time in 360° to generate a stress at the start point of the rotating range or opening and closing range of the hinge mechanism, and causing the other cam set to generate a stress at the end point of the rotating or opening and closing range. The hinge mechanism of the present invention achieves durability, good feeling, and size and weight reduction.
