Patent ID: 8286307

Claim:
A multi-staged hinge assembly, comprising: a spindle having a first portion and a second portion; an elastic device being disposed on the first portion and adapted to provide an axial thrust towards the second portion; a first movable component comprising a first inner periphery to define a first axial hole for the first movable component to be penetrated through the second portion of the spindle; a second movable component comprising a second inner periphery to define a second axial hole for the second movable component to be penetrated through the second portion of the spindle, in which the second movable component is adjacent to the first movable component and opposite to the elastic device; and a third movable component comprising a third axial hole for the third movable component to be penetrated through the second portion of the spindle and to be connected with an end of the second movable component, in which the end is opposite to the other end of the second movable component abutting against the first movable component; wherein the spindle has a non-circular cross-section, in which the first inner periphery has a shape corresponding to the non-circular cross-section, the second inner periphery is circular, and the third axial hole has a cross-section which is circular, therefore, the first movable component is adapted to travel in a non-rotating displacement toward a direction away from the first portion when the first movable component is subjected to the axial thrust, while the second movable component is adapted to travel in a non-displacing rotation in response to an action resulting from the first movable component, the third movable component is capable of traveling in the non-displacing rotation along with the second movable component.
