The door stop device comprises two pivotally interconnected links for pivoting, one link, to a door and, the other link, to a fixed part on which the door is pivotally mounted. The links are capable of being unfolded and folded when opening and closing the door. A first link is extended beyond its pivotal connection to the other link by two semi-cams. Each of the semi-cams defines a stop notch. A cam follower movably mounted in the second link is capable of engaging the stop notches under the action of a spring in the second link to create a retention in the course of the unfolding of the links. This retention may be overcome to permit the return of the links to their folded position. |
