Title:
APPARATUS FOR GUIDING ROTATION OF GEAR HINGE PART IN ROTARY DOOR
Document Type and Number:
WIPO Patent Application WO/2021/034067
Kind Code:
A2
Abstract:
The present invention relates to an apparatus which can guide the stable rotation, between a first support bracket connected and fixed to a support frame side of a doorcase and a second support bracket connected and fixed to a door side, of a gear hinge part constituting a rotary door, and relates to an apparatus for guiding the rotation of a gear hinge part of a rotary door, wherein the compressive stress and tensile stress generated in a lower end gear hinge part below the neutral axis of the door and in an upper end gear hinge part above the neutral axis of the door, respectively, by a rotational moment applied to the gear hinge part through a second support bracket due to the weight of the door is minimized. Thus, not only can the ability of the door to open and close with precision be achieved and maintained, damage to components or the generation of friction noise due to friction generated in a door hinge can be minimized.
