Abstract

L'invention décrit un ascenseur (1) qui comporte une cage (5) d'ascenseur, une cabine (3) pouvant être déplacée verticalement dans la cage (5) d'ascenseur et plusieurs portes palières (7) agencées à différentes hauteurs dans la cage d'ascenseur pourvues respectivement d'un encadrement de porte (8) stationnaire et d'au moins un vantail (6) pouvant être déplacé horizontalement. Chaque porte palière (7) comporte un mécanisme de déverrouillage (13) au moyen duquel l'ouverture de la porte palière (7) doit être verrouillée et déverrouillée lorsqu'un élément d'actionnement (19) du mécanisme de déverrouillage (13) est actionné. Le mécanisme de déverrouillage (13) comporte un premier et un deuxième élément de verrou (15, 17), le premier élément de verrou (15) étant disposé par ex. contre le vantail (6) de la porte palière (7) et le deuxième élément de verrou (17) étant disposé par ex. contre l'encadrement de porte (8) de la porte palière (7) ou à un autre vantail. Le premier et le deuxième élément de verrou (15, 17) peuvent être déplacés l'un par rapport à l'autre entre une première position et une deuxième position dans une direction de déverrouillage (35) perpendiculaire à l'horizontale en déplaçant l'élément d'actionnement (19). Le premier et le deuxième élément de verrou (15, 17) s'engrènent l'un dans l'autre dans la première position par complémentarité de forme de telle sorte qu'un déplacement horizontal du vantail (6) par rapport à l'encadrement de porte (8) est bloqué. Dans la deuxième position, le premier et le deuxième élément de verrou (15, 17) sont libérés de la complémentarité de forme. Le mécanisme de déverrouillage (13) selon l'invention peut être construit selon une structure très simple et, grâce à la possibilité de l'actionner avec un mécanisme d'actionnement (11) semblable à un robot, on peut se passer d'un ajustement précis coûteux de composants d'un mécanisme d'ouverture (2) de portes palières.
