Title (EN) ELEVATOR DOOR INTERLOCK
(FR) VERROUILLAGE DE PORTES D'ASCENSEUR
Abstract:
(EN) An elevator door interlock has a position indicator at each landing. There is an elongate vane (30) pivotally mounted in a fixed position with respect to the car door (14) for movement between a first position, preferably several degrees rotated from the perpendicular, and a second position, generally perpendicular to the surface of the door (14). The interlock (12) also includes a swing latch (32) comprising a latch arm (34) and a contact plate (36). A stop plate (38) is mounted in a fixed position with respect to the elevator car (10). The vane (30) is mounted on a spring-biased hinge (48-50) such that the contact plate (360) extends into the place of the stop plate (38) to prevent further opening of the elevator door (14, 16).
(FR) L'invention concerne un système de verrouillage de portes d'ascenseur à indicateur de position sur chaque palier. Une palette allongée (30) est montée pivotante dans une position fixe par rapport à la porte de la cabine d'ascenseur (14), pour se déplacer entre une première position, de préférence en rotation de plusieurs degrés par rapport à la perpendiculaire, et une seconde position, généralement perpendiculaire à la surface de la porte (14). Le système (12) comprend aussi un verrou bascule (32) ayant un bras de verrouillage (34) et une plaque de contact (36). Une plaque d'arrêt (38) est montée en position fixe par rapport à la cabine d'ascenseur (10). La palette (30) est montée sur charnière à ressort (48-50), de sorte que la plaque de contact (360) s'étende sur l'emplacement de la plaque d'arrêt (38) pour empêcher la poursuite de l'ouverture de la porte de l'ascenseur (14, 16).
