ABSTRACT:
A self-closing door device includes a torsion bar which is connected at its ends between the hinged side of the door and the door jamb. The torsion bar is arranged to twist about as well as bend along its longitudinal axis and in a manner which tends to decelerate the door as the door approaches its closed position.
