Abstract:
1. A rotational hinge comprising: a first casing linkage; a second casing linkage; a hinge linkage; and a synchronization linkage that extends in a first direction and a second direction to form a bend, wherein the synchronization linkage is coupled to the first casing linkage and the second casing linkage and synchronizes a fixed rotational axis and a moving rotational axis that provides one or more degrees of rotation, wherein the first casing linkage comprises a first shaft and the second casing linkage comprises a second shaft, each include shafts to which the synchronization linkage is coupled, wherein a distance between a central axis of the first shaft and an axis passing through a first coupling point of the synchronization linkage to the first shaft is different from a distance between a central axis of the second shaft and an axis passing through a second coupling point of the synchronization linkage to the second casing linkage.
