CA 2251134

A simplified elevator car door lock assembly locks an elevator car door if the car is outside a landing zone and there is an attempt to open those doors. The car doors are connected to the hoistway doors by a pair of vanes (34, 36) mounted on the car door and a pair of rollers (29a, 29b) mounted on the hoistway door. A third vane (38) is attached to the car door and follows a cam path on the car door to lock the car doors if the car is not in a landing zone. Conversely, the third vane senses if the car is in a landing zone and does not lock the car door if it is moved.

Un ensemble de verrouillage simplifié pour portes de cabine d'ascenseur bloque les portes de la cabine d'ascenseur si cette dernière ne se situe pas au niveau d'une zone palière et si quelqu'un tente d'ouvrir lesdites portes. Les portes de la cabine sont connectées aux portes du compartiment par une paire de palettes (34, 36) montées sur la porte de la cabine et une paire de galets (29a, 29b) montés sur la porte du compartiment. Une troisème palette (38) est fixée à la porte de la cabine et suit un chemin de came sur la porte de la cabine pour bloquer les portes de la cabine si cette dernière ne se situe pas au niveau d'une zone palière. Inversement, si la troisième palette détecte la présence de la cabine dans une zone palière, elle ne bloque pas la porte de la cabine si quelqu'un la manoeuvre.
