A hinge device for corotation is provided to prevent an impact resulting from the opening and shutting of door in a double-way rotary door in which the door is consecutively folded. A hinge device for corotation comprises a first bracket(10a) and a second bracket(10b) located opposite to each other in adjacent doors and each equipped with a fixed pin(21) and a movable pin(23) sliding relative to the fixed pin, a shaft(30) arranged between the first bracket and the second bracket, and a torque generator including a first link member(50a) and a second link member(50b). The first link member is combined to the three points formed by the fixed pin of the first bracket and the movable pin of the second bracket around the shaft. The second link member intersects the first link member and combined to the three points formed by the fixed pin of the second bracket and the movable pin of the first bracket. The first and the second link member have elasticity. |
