Toggle-type door stop device in particular for an automobile vehicle
First Claim
1. A toggle-type door stop device in particular for an automobile vehicle comprising two links for pivotally mounting respectively to a fixed part for example a body, and to a door which is pivotally mounted on the fixed part, the links being interconnected to pivot about a pivot axis so as to be capable of occupying selectively a folded position, corresponding to closure of said door, and an unfolded position corresponding to an opening of said door, a first of said links being extended beyond said pivot axis to form two semi-cams each of which defines at least one stop notch, cam follower means located outside the second of said links for cooperation with the stop notches of said semi-cams and movably mounted on said second link, elastically yieldable means carried by said second link and biasing said cam follower means into contact with said semi-cams, said semi-cams being capable of creating a retention in cooperation with said cam follower means when opening said links, said retention being capable of being overcome in opposition to the action of said elastically yieldable means for allowing said links to return to said folded position of said links.

Abstract
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.
