  • Publication number: 20210277709
    Abstract: A door having a finger pinch prevention function is provided that can prevent a finger jamming accident between a door frame and a door by making sure that there is no gap between the door frame and the door coupled to one side of the door frame, in the process of opening and closing the door. The door has an effect of preventing a finger from being caught because a gap does not occur in a corner portion where the door and a coupling frame abut, even when the door is opened or closed, by combining the coupling frame coupled to one side of the door frame and the door through a hinge. Furthermore, by configuring a cover in the corner portion where the coupling frame and the door abut, the hinge is not exposed to the outside, so that the appearance can be seen appealing.
