Abstract:
1. A hinge assembly comprising: a stationary member having a position protrusion; a rotating member defining a receiving depression to receive the position protrusion; and a pivotal shaft comprising a shaft portion and an elastic portion integrally formed with the shaft portion, the shaft portion having a first end and an opposite second end, the elastic portion being hemispherical and having a top integrally formed on the second end of the shaft portion and an opposite bottom facing toward the first end and surrounding the shaft portion; wherein the pivotal shaft is made of amorphous alloy, the stationary member and the rotating member are positioned on the pivotal shaft from the first end, the position protrusion is received in the receiving depression; the rotating member is non-rotatable relative to the pivotal shaft, and the stationary member is rotatable relative to the pivotal shaft; the bottom of the elastic portion axially resisting against the rotating member thereby providing an axial force pushing the rotating member to firmly engage with the stationary member.
