Abstract: A door closer device for connection between a door leaf and a door frame serves to automatically close the door after opening. The device has a housing that is received in the door leaf and a chain have one end connected inside the housing and the other end connected to the door frame. A spring connects the chain to the housing and serves to urge the chain into the housing bore. The chain links are pivotally connected plates with opposed side edges arranged such that a side edge of a link faces a corresponding side edge of an adjacent link. Each side edge defines a first portion and a second portion. The facing first portions of adjacent links are adapted to come into abutment when the links are arranged such that the longitudinal axis of the chain extends substantially in a straight line so as to prevent the links from pivoting in a first direction. The facing second portions of adjacent links are adapted to come into abutment when the links are pivoted in a second direction opposite to the first direction such that the articulation is limited and the links describe a line that substantially follows an arc.
