Abstract: A door closer has a first arm (4, 14) which is pivotally attached to the door case (2), a second arm (5, 15) which is pivotally attached to the door leaf (1), the opposite ends of the two arms being pivotally connected to each other (at C), and a spring biased driving device (6, 16) which is pivotally attached partly to the door case (at E), partly to the linkage system formed by the arm (4, 5; 14, 15). According to the invention the driving device (6, 16) is pivotally attached to the second arm (5, 15) at a distance from its joint (6) on the first arm (4, 14), and its joint (E) on the door case is located between the joints (A and B respectively) of the first and second arms (4, 5; 14, 15) on the door case and the door leaf respectively, the joint (B) of the second arm (5, 15) being located closest to the hinge joint (D) of the door.
