ABSTRACT:
A door closing hinge device includes two flaps for attaching to a door frame and a door panel, a seat and a housing attached to the flaps. A follower is slidably disposed in the housing, and includes an inclined surface for engaging with an inclined surface of the seat, and for moving the follower up and down relative to the housing when the follower and the housing are rotated relative to the seat. A guiding device may guide the follower to move up and down relative to the housing, and a forcing device may force the follower and the door panel to rotate relative to the door frame back to an original position where the inclined surfaces of the seat and the follower are engaged with each other.
