Abstract

L'invention concerne un mécanisme de verrouillage côté cabine qui comprend un élément crochet côté verrouillage supporté de manière rotative par une porte côté cabine (11A), et un élément crochet de fixation qui est disposé sur une cage (10) et vient en prise de manière libérable avec l'élément crochet côté verrouillage. Une paire de portes côté cabine (11A, 11B) ont des sections de chevauchement (311A, 311B) qui se chevauchent mutuellement dans un état verrouillé dans lequel les portes côté cabine (11A, 11b) sont verrouillées par le mécanisme de verrouillage côté cabine. Un intervalle de verrouillage est formé entre l'élément crochet côté verrouillage et l'élément crochet de fixation dans l'état verrouillé. La longueur (L3) du chevauchement entre les sections de chevauchement est supérieure à la longueur (L1) de l'intervalle de verrouillage dans la direction d'ouverture/fermeture de la paire de portes de cabine.
