Abstract:
The present invention relates to a hand-jamming prevention hinge for a door, the hand-jamming prevention hinge comprising: a first hinge portion which is perpendicularly provided on an inner surface of a plate-shaped first base having one or more bolt holes and a certain thickness so as to be fixed to each of upper and lower portions of a door frame by using bolts, and includes a pinion gear formed in a fan-shape; a housing, which is formed in a square pillar shape having one open side and an empty inside, provided on a surface of a plate-shaped second base having one or more bolt holes and a certain thickness to be fixed on each of upper and lower side surfaces of a door by using bolts; and a second hinge portion which includes a rack gear rotationally moved while being engaged with the pinion gear and rotated about the pinion gear as a rotary shaft, and is provided on an inner circumferential surface of the housing. Thus, the hand-jamming prevention hinge for a door is capable of reducing and minimizing an interval between the door frame and an outside gap of the door by opening the door while restricting the turning radius of the door.
