Abstract

See full text

The present invention relates to a device capable of guiding a stable rotational actuation between a first support bracket fixedly connected to a supporting frame side of a door frame and a second support bracket fixedly connected to the door side in a gear hinge unit constituting a rotating door, specifically, in a door hinge in which a gear hinge unit is provided between the first support bracket fixedly connected to the support frame side of the door frame and the second support bracket fixedly connected to the door side, by minimizing the compressive stress generated in the lower gear hinge unit under a neutral axis of the door and the tensile stress generated in the upper gear hinge unit above the neutral axis of the door by the rotational moment applied to the gear hinge unit due to the load of the door, it is possible not only to secure and maintain the correct opening/closing performance of the door, but also to minimize damage to parts caused by friction or friction noise in the door hinge.
