Abstract
A dual swing hinge structure includes two fixed base frames each having a receiving groove and a pivot hole extending across the receiving groove, a first bracket, which has two coupling arms respectively inserted into the receiving grooves of the base frame and pivotally coupled to the pivot holes of the base frames with pivot pins and a mounting plate fastened to a first movable member, a second bracket, which has two coupling arms respectively pivotally coupled to the pivot pins that pivotally secure the first bracket to the base frames and a mounting plate fastened to a second movable member, and two first retaining members and two second retaining members respectively affixed to the coupling arms of the first bracket and the coupling arms of the second bracket and respectively coupled to the pivot pins for imparting a different torque force to the pivot pins such that the first bracket is immovable when the second bracket is biased relative to the base frames, and the second bracket is moved with the first bracket relative to the base frames when the first bracket is biased relative to the base frames.
