ABSTRACT:
This invention relates to a device ensuring automatic closure of pivoting doors and for holding them in open position. The device includes a fixed box mounted on the door (or frame) and supporting a pivoting arm subjected to the action of a return element. A fixed slide rail is mounted on the frame and a connecting element is positioned between the pivoting arm and the slide rail. The connection between the pivoting arm and the slide rail is obtained by way of a sliding rod, retractable inside the arm. The rod is adapted to be blocked automatically when it projects from the arm by a determined length corresponding to a given degree of opening of the door.
