Abstract

L'invention concerne un dispositif (32) pour retenir une porte en position ouverte, qui comporte : un premier élément de prise (40), qui pivote à l'intérieur d'un trou pivot (24) autour d'un premier axe (X1) en même temps qu'une tige articulée (14), à mesure que la porte est ouverte et fermée ; et un second élément de prise (66), qui peut pivoter autour d'un second axe (X2), parallèle au premier axe. Quand la porte approche d'une position ouverte (FIG. 4d), un élément saillant de prise (62-1) glisse sur le second élément de prise (66) et entre en prise avec celui-ci, et fait pivoter et repousse cet élément vers l'extérieur d'une trajectoire de déplacement contre la force de pression d'un ressort. Si l'on essaie de fermer la porte à partir de la position ouverte, le second élément de prise (66) entre en prise avec l'élément saillant de prise (62-1) de manière à arrêter le pivotement de celui-ci, et à retenir la porte en position ouverte. La ligne d'action d'une deuxième force (F2), au moyen de laquelle l'élément saillant de prise fait pivoter le second élément de prise contre la force de pression du ressort lorsqu'on ferme la porte, est réglée de manière à se déployer suivant une trajectoire plus proche du second axe (X2) que la ligne d'action d'une première force (F1), au moyen de laquelle l'élément saillant de prise fait pivoter le second élément de prise contre la force de pression du ressort lorsqu'on ouvre la porte.
